40 A pparatus and Materials
4.1 Extractor—For purposes of this test.
an acceptable extractor is one that will
impart sufficient agitation to the mixture to
(1) prevent stratification of the sample and
extraction fluid and (2) ensure thai all sample
surfaces are continuously brought into
contact with well-mixed extraction fluid.
Examples of suitable extractors are shown in
Figures 1-3 of this method and are available
from: Associated Designs & Manufacturing
Co.. Alexandria. Virginia; Clas-Col
Apparatus Co.. Terre Haute. Indiana:
Millrpore. Bedford. Massachusetts: and
Rexnerd. Milwaukee. Wisconsin.
4.2 pH meter or pH controller—Accurate
to O.OS pH units with temperature
compensation.
4.3 Filter holder—Capable of supporting a
0.45-tim Ulter membrane «od of withstanding
the pressure needed to accomplish
separation. Suitable filter holders raage from
simple vacuum units to relatively complex
systems lhat-can exert up to 5.3 4g/cor1 (75
psi) of presume. The iype of filter bolder used
depuds upon the properties of the mixture to
be filtered. Filler holders known to EPA and
deemed suitable for use are listed in Table 1.
4.4 Filter membrane—Filter trwmbnme
suitable for conducting the required filtration
shall be fabricated from a material that (11 is
not physically dunned by the waste material
to be filtered and (2} does aet Absorb or teach
the chemical species for which a waste's EP
extract will be analyzed. Table 2 lists filter
media known to the agency to be suitable for
solid waste testing.
4.4.1 In cases of doubt about physical
effects on the filter, contact the filter
manufacturer to determine if the membrane
or the prefllter is adversely affected by the
particular waste. If no information is
available, submerge the filter in the waste's
liquid phase. A filler that undergoes visible
physical change after 48 hours (i.e- curls.
dissolves, shrink*, or swells) is unsuitable for
use.
4.4.2 To test for absorption or leaching by
the filter
4.4.2.1 Prepare a standard solution of the
chemical species oi interest.
4.4JL2 Analyze the standard for its
concentration of the chemical speoes.
4.4.13 Filter the standard and reanalyze.
If the concentration of the filtrate differs from
that of. the original standard, then the filter
membrane leaches or absorbs ant or more of
the chemical apecies and is not usable in this
test method.
4.5 Structural integrity tester—A device
meeting the specifications shown in Figure 4
and having a 3.18-cm (1.25-in) diameter
hammer weighing 0.33 kg (0.73 Ib) with a free
fall of 15.24 cm (6 in) shall be used. This
device is available from Associated Design
and Manufacturing Company, Alexandria.
VA 22314. as Part No. 125. or it may be
fabricated to meet these specifications.
5S> Reagents
5.1 Reagent grade chemicals shall be used
in all tests. Unless otherwise indicated, it is
intended that all reagents shall conform to
the specifications of the Committee on
Analytical Reagents of the American
Chemical Society, where such specifications
are available. Other grades may be used.
provided it is lint ascertained that the
reagent is of sufficiently high purity to permit
its use without lessening the accuracy of the
determination.
5.2 Reagent water. All references to water
in this method refer to reagent water, as
defined in Chapter One.
5J Acetic acid (6.SN1. CH>COOH. This
can be made by diluting concentrated glacial
acetic acid (17.5N) by adding 57 ml glacial
acetic acid to 1.000 ml of water and diluting
to 2 liters. The glacial acetic acid must be of
high purity and monitored for impurities.
5.4 Analytical standards should be
prepared according to the applicable
analytical methods.
6.0 Sample Collection. Preservation, and
Handling
6.1 All sample* must be collected using a
sampling plan that addresses the
considerations discussed in Chapter Nine of
this mapn^|
6.2 Preservatives must not be added to
samples.
0.3 Samples can be refrigerated if it is
determined that refrigeration will not affect
'.he integrity of 4he sample.
"0 Procedure
7.1 If the waste does not contain any free
liquid, go to Sup 73. If the sample is liquid or
multiphase, continue as follows. Weigh filter
membrane and prefUter to ±0.01 g. Handle
membrane and prefilters with blunt curved-
tip forceps w vacnnrn tweezers, or by
applying suction with « pipet.
7.2 Assemble filter holder, membranes.
and pretiltgis following the manufacturer's
instructions. Place the 0.4t-pm membrane on
the support screen and add prefilters in
ascending order of pore size. Do not prewet
filter membrane.
7.3 Weigh out a representative subsample
of the waste (100 g minimum).
7.4 Allow slurries to stand, to permit the
solid phase to settle. Wastes that settle
slowly may be centrifnsed prior to filtration.
7.5 Wet the fii*«r wtth s small portion of
the liquid phase from the waste or from the
extraction mixture. Transfer the remaining
maiensl to the filter bolder and apply
vacuum or gentle pressure (10-15 psi) until all
liquid passes through the filter. Stop filtration
when air or pressurizing gas moves through
the membrane. If this point is not reached
under vacuum «r gentle pressure, slowly
increase the pressure in 10-psi increments to
75 psi. Halt fUtrsuon when liquid flow stops.
This liquid will constitute part or all of the
extract (refer to Step 7.16). The liquid should
be .refrigerated until time of analysis.
Note: OH samples or samples containing oil
are treated in exactly the same way as any
other sample. The liquid portion of the
sample is filtered and treated as part of the
EP extract. If the liquid portion of the sample
will not pass through the filter {usually the
case with heavy oils or greases), it should be
carried through the EP extraction as a solid.
7.6 Remove the solid phase and Glter
media and. while not allowing them to dry.
weigh to ± 0.01 g. The wet weight of the
residue is determined by calculating the
weight difference between the weight of the
Filters (Step 7.1) and the weight of the solid
phase and the filter media.
7.7 The waste will be handled differently
from this point on. depending on whether it
contains more or less than 0.5% solids. If the
sample appears to have <0.5% solids.
determine the percent solids exactly (see
Note below) by the following procedure:
7.7.1 Dry the filter and residue at 80 'C
until two successive weighings yield the
same value.
7.7.2 Calculate the percent solids, usms
she following equation:
weight of
filtered solid
and filters
tared weight
of filters
solids
initial weight of
waste material
Nates This procedure is used onry to
determine whether the solid must be
extracted or whether it can be discarded
unekiracied. It is not used in T°l'-"1°''nB the
amount of water or acid to use in the
extraction step. Do not extract solid material
that has been dried at 80 *€. A new sample
will have to be used for extraction if a
percent solids determination «'performed.
7.8 If the solid constitutes 3 J cm1 or passes through a 95-
mm (0.375-in.) standard sieve, the operator
shall proceed to Step 7.11. If the surface urea
is smaller or the particle sue larger than
specified above, the solid material shall lie
prepared for extraction by crushing, cutting.
or grinding the material so that it passes
through a 9-5-mm (0.375-in.) sieve or. if the
material is in a smgJe pteoe. by subjecting the
material to the "Structural Integrity
Procedure" described in Step 7.10.
7.10 Structural Integrity Procedure (SIP).
7.10.1 Cat a 3.3-cm diameter by 7.1 -cm
long cylinder from the waste maienal. If the
waste hat been treated using • fixation
process, the wsste may be cast in the form of
a cylinder end allowed to cure for 30 days
prior to testing.
7JOJ Place waste into sample holder snu
assemble the tester. Raise the hammer to its
maximum height and drop. Repeat 14
additional times.
7.10.3 Remove solid material from tester

7.12 Pla' e the appropriate amount of
material (n fer to Step 7.11) into the extractor
and add 1'. times its weight with water.
7.13 After the solid material and

the solution shall be decreased to 5.0
±0 2 by slowly adding 0.5N acetic acid.
If the pH is <5.0. no acetic acid should
be added. The pH of the solution shall
b: monitored, as described below.

Where:
V = mL water to be added.
W = Weight in g of solid charged to extractor.
A = mL of 0.5N acetic acid added during

7.15 The material in the extractor
shall be separated into its component
liquid and solid phases in the following
manner
7.15.1 Allow slurries to stand to
permit the solid phase to settle (wastes
that are slow to settle may be
centrifuged prior to nitration) and set up
the filter apparatus (refer to Steps 4.3
and 4.4).
7.15.2 Wet the filter with a small
portion of the liquid phase from the
waste or from the extracted mixture.
Transfer the remaining material to the
filter holder and apply vacuum or gentle
pressure (10-15 psi) until all liquid
passes through the filter. Stop filtration
when air or pressurized gas moves
through the membrane. If this point is
not reached under vacuum or gentle
pressure, slowly increase the pressure in
10-psi increments to 75 psi. Halt
filtration when liquid flow stops.
7.16 The liquids resulting from Steps
7.5 and 7.15 shall be combined. This
combined liquid (or waste itself, if it has
< 0.5% solids, as noted in Step 7.8) is
the extract and shall be analyzed for the
presence of any of the contaminants
specified in 40 CFR 261.24 using the
analytical procedures as designated in
Step 7.17.
7.17 The extract is then prepared
and analyzed using the appropriate
TABLE 1.—EPA-APPROVED FILTER HOLDERS
analytical methods described in
Chapters Three and Four of this manual.
Notr. If the EP extract includes two phi^l
concentration of contaminants is determin^
by using a simple weighted average. For
example: An EP extract contains SO mL of oil
and 1.000 mL of an aqueous phase.
Contaminant concentrations are determined
for each phase. The final contamination
concentration is taken to be:
SO X contaminant
cone, in oil
1.000 X
contaminant cone.
of aqueous phase
1050
Note: in cases where a contaminant was
not detected, use the MDL in the calculation.
For example, if the MDL in the oily phase is
100 mg/L and 1 mg/L in the aqueous phase.
the reporting limit would be 6 mg/L (rounded
to the nearest ing). If the regulatory threshold
is 5 mg/L the waste may be EP toxic and
results of the analysis are inconclusive.
7.18 The extract concentrations are
compared with the maximum
contamination limits listed in 40 CFR
281.24. If the extract concentrations are
greater than or equal to the respective
values, the waste then ia considered to
exhibit the characteristic of Extraction
Procedure Toxicity.

56 FR 5910-5915
February 13, 1991
(RCRA Cluster I, HSWA Rule)
Note: This Revision Checklist addresses an interim final rule which suspends the Toxicity
Characteristic (TC) rule (see 55 FR 11798, March 29, 1990, Revision Checklist 74) for certain
used Chlorofluorocarbon refrigerants which exhibit the toxicity characteristic and which are recycled.
The exemption only applies if the refrigerants are reclaimed for reuse. This interim final rule
provides for a standard which is narrower in scope than would be imposed in the final TC rule.
Thus, States are not required to mandate this narrower-in-scope standard V, and the affected
citation is designated as optional. Section 3009 of RCRA, however, provides that States may
impose requirements that are broader in scope or more stringent than those imposed under
Federal regulations.

SUMMARY: On March 29. 1990, the
Environmental Protection Agency (EPA)
promulgated revisions to the toxicity
characteristic, one of several
characteristics used to identify waste
regulated as hazardous under Subtitle C
of the Resource Conservation and
Recovery Act (RCRA). Since the
promulgation of the Toxicity
Characteristic (TCI. the Agency has
received information that the rule's
immediate application may cause _
certain used chlorofluorocarbon (CFC)
refrigerants to be subject to hazardous
waste regulations becanse-tfaey exhibit

Objecting used CFC refrigerants to
Subtitle C regulations will promote
continued or increased venting.

substances in the stratoaphere^As a
result of this new information and to
allow time for gathering additional
information and giving all relevant facts
careful consideration, the Agency is

L Background
A.' Refrigeration System Operation
Vapor compression refrigeration
systems typically use CFC ret
as the working fluid. The most
refrigerants include CFC-11. tZ. 114, 802
and HCFC-22. These cycles arvdoead
systems, relying on the ability to
continually compress and evagasxctfae
refrigerants to provide the proper he*t
transfer for cooling.
CFC-11 is typically a liquidat room
temperature, but because its botilBf
point is around 75 *P. it volatilizes
easily. An infrequently used refrigerant.
CFC-113, also has a high boilingpaint
(117 *F). However, the other more
common refrigerants, such as CEC-12
and HCFC-22. have very low bofllag
points (—21 and —41 degrees P •
respectively), which causa thearte

B. RCRA Applicability
• . ; RCRA regulations apply to materials
' : that an solid wastes (including solids,
liquids, semi-solids, and contained
-yasesl. as that term is defined in 40 CFR
vrJZ8L2. Used Refrigerants are considered
r ipent materials, and if reclaimed, are
solid wastes under 40 CFR 281.2(c)(3).
However, a limited subset of used
refrigerant Le~ those which an used or
assaad without prior reclamation, are
s*ta*faject to regulation under the
RCRA hazardous waste program (see 40
CFR261.2(e)(l)(ii)).
. On March 29, 1990 (55 FR 11798), EPA
promulgated the Toxicity Characteristic
Jo replace the EP toxicity characteristic.
:(Tha TC want into effect September 25,
'1980.) The Toxicity Characteristic is
used to identify solid wastes which are
identified as hazardous based on the
pretence of constituents that may leach

the docket there is no documentation of

determine whether used CFC
refrigerants are TC hazardous. EPA also
solicits comment on whether the
suspension should be extended to
hydrofhiorocarbon (HFC) refrigerants.
which are being used as refrigerants (for
example, in mobile air conditioning
systems): EPA has no data at all on
whether MFCs would exhibit any
hazardous waste characteristics when
removed from refrigeration systems.
C. Previous EPA Actions on
Rfffrtgfnnts
The issue of RCRA applicability to
refrigerants being recycled has bee*
discussed previously; see the July 28.
19V Federal Register notice (54 FR
31335) describing the states of recycled
refrigerants under the I960 Federal
hazardous waste regulations. Under the
regulations in place from 1900 to 1880.
recycled refrigerants were unlikely to be
Federally regulated es nazardoas
wastes because they would not have
exhibited any of the «fr«f^p*»*p«MM of
hazardous waste, nor did they fit any of
the hazardous waste listing descriptions.
However, as discussed above, the TC
regulation promulgated on Match 28.
1980. wkich added new constituents to
the Toxicity Characteristic, may change
the RCRA regulatciy states of those
recycled refrigerants containing carbon
tetrachloride or other Toxkity
Characteristic constituents.
No commenters on the original
Toxicity Characteristic proposal raised
the issue of possible negative impacts
on recycling of used refrigerants if they
were to become regulated as hazardous
wastes. One reason this may have
occurred ie that at .the time ef IBM
original TC proposal flon* It. Iff* ««e
51 FR 21648) most refrigerants were
being vented and recycling was not
feasible.
EPA has taken a related action tinder
the Clean Air Act by issuing an
Advanced Notice of Proposed
Rutemaking (ANPRM) on May 1.1990
(55 FR 18258) to develop a national CFC
and halon recycling program. Some
commenters on that notice raised
concerns about RCRA applicability to
recycled refrigerants and described
potential disruption of recycling markets
if refrigerant is managed as a hazardous
waste under RCRA. However, the
commenters did not specifically mention
the Toxicity Characteristic.
D. Regulations under the Clean Air Act
The recently enacted amendments to
the Clean Air Act require EPA. by 1992.
to isaae regulations regarding the use
and disposal of certain CFCs in
appliances and industrial process
refr jgKMtirm anita. The regulations ntust
include IBQ uuementB to1
recapture and recycling and ensure sale
disposal. The asneadraeats. as a general
nun. also prohibit venting of certain
CFCs to the environment
The new Clean Air Act authority is
the Agency's best available tool to limit
CFC emiseieas. The Clean Air Act
authority enables the Agency to regulate
the handling, recycling, reuse and
disposal of CFCs by refrigerant
recyden. service technicians and
equipment owners and manufacturers.
When EPA proposes and finalizes a
prohibition on venting
chlorofluorocarbons under the Clean Air
Act and the prohibition becomes
effective, the Agency will reconsider the
issae of RCRA applicability to used CFC
refrigerants being recycled.
II. Application of Existing Regulatory
Framework
A. Definition of Solid Waste
One of the first questions that arises
in determining RCRA applicability to
refrigeration system maintenance and
repair is whether a material is a solid
waste. The hazardous waste regulations
of RCRA Subtitle C apply to materials
that are "solid wastes." which are
defined in RCRA section 1004(27) as
* * * discarded material including 10110.
liquid, semi-solid or contained gawons
material muMng from indtutriaL
commercial, mining, and agricultural
operations, and from community achvitiei
Contained gases thus clearly are solid
wastes under RCRA, whereas
uncontemed gases not associated with
solid waste management units are
outside of RCRA.
As stated in the July 28,1969 Feden
Register (54 FR 31336). EPA's regulatil
classify the used refrigerants as spent
materials that are solid wastes when
reclaimed. (The refrigerants must be
collected as a contained gas under this
scenario.) See 40 CFR 261.2(cM3). If the
waste also exhibits a characteristic of a
hazardous waste, it is a hazardous
waste in addition to being a solid waste.
Thus, the equipment servicer who must
remove the chlorofluorocarbon
refrigerants in order to service the
equipment must decide whether to vent
them (and thus avoid hazardous waste
regulatory requirements) or collect them
and possibly be required to manage
them as hazardous wastes. EPA is
concerned that, if the refrigerants are
regulated as hazardous wastes, most
servicers will vent the material rather
than collect it for recycling.
B. Refrigerant Handlers' RCRA
Requirements
This section presents the hazardous
waste requirements for handlers ef used
CFC refrigerants being reclaimed, if
those used CFC refrigerants were to be
classified as hazardous wastes because
they exhibit the ToKiciry Characteristic.
The requirements described here era
suspended by today's action (discul
farmer m section IV of this notice).*
Currently, the owners of refrigeration
equipment using CFC refrigerant as die
heat transfer fluid are considered
haurdous waste generators if the used
CFC refrigerant exhibits the
characteristic of Toxicity, and if they
collect the used CFC refrigerant for
reclamation or disposal. In addition.
parties who repair or maintain the
refrigeration equipment under contract
with the equipment owners would be
"co-generators" if their actions produced
hazardous waste, or caused it to be
subject to regulation (see 45 FR 72026,
October 30.1890). Parties co-generating
hazardous waste must arrange among
themselves who is to take responsibility
for managing the hazardous waste,
although all parties remain potentially
liable for hazardous waste
mismanagement
As of September 25.1990. generators
who generate more than 1000 kg of
hazardous waste per month must
manege their TC hazardous wastes
according to the requirements in 40 CFR
parts 261 and 262 and other relevant
parts of the hazardous waste
regulations. For generators of 1QO-UOO
kg of hazardous waste per month
effective date fat managing TC
hazardous wastes according to the
hazardous waste icquiieaiciits is March
29.1991. (Generators of lees than 109kg
-------
012 Federal Register / VoL 56, No. 30 / Wednesday. Febrnary 13.
Rules and Regulations
hazardous waste per month an
conditionally exempt from hazardoui
waste management standards.)
In a scenario in which the
refrigeration equipment servicer collects
the CFC refrigerant and transports it
from a large quantity generator's site for
recycling, that servicer acts as a
transporter (in addition to being a co-
generator) and must comply with the
requirements in 40 CFR part 263 if the
used CFC refrigerant exhibits a
hazardous waste characteristic.
Transporters may hold hazardous
wastes at "transfer facilities" for up to
ten days, consistent with activities
undertaken in the normal course of
transportation, without needing a RCRA
storage permit
As of September 25.1990, the
recycling facility accepting CFC
refrigerants that are hazardous wastes
from large quantity generators (greater
than 1000 kg/month) must meet the
definition of a "designated facility."
which requires that the facility either
has a permit or interim status, or meets
certain other conditions as a recycling
facility (see 40 CFR 200.10 for the
definition of designated facility).
IIL IstiiM Arisinf From the TC Rule
A. Impacts on Recycling Market*
EPA has received information since
promulgation of the TC indicating that
certain companies currently recycling
CFC refrigerants may stop doing so if
they must manage the CFC refrigerants
as hazardous wastes. See Items No. 2-7
in the public docket for this notice.
These companies and other groups
generally cite the cost and complexity of
the hazardous waste regulations, along
with specific RCRA requirements such
as manifesting, and other requirements
that may be imposed at the local level
as a result of the hazardous waste
requirements (i.e~ rezoning refrigerant
distribution centers as hazardous waste
transfer stations), as reasons that
recycling will Himini«h or cease.
Although EPA is still evaluating the
merits of the arguments presented by
the parties submitting this information.
EPA is concerned that some of the
results suggested may cause serious
environmental harm, the nature and
significance of which EPA did not
explore during the TC rulemaking. EPA
is concerned that the increased
requirements associated with regulating
refrigerants as hazardous wastes will
result in increased venting. EPA has not
considered the feasibility of
administrative options to reduce the
impacts on recycling of these materials
under current RCRA regulations.
Therefore. EPA is suspending
application of the rule in order to have
time to evaluate these issues.
In order to evaluate these issues, EPA
is soliciting public comment on whether
handling used CFC refrigerants as a
hazardous waste is causing or will cause
a decrease in current recycling rates,
and whether the decrease (if any) is or
will be occurring for the reasons these
parties put forward, or for other reasons.
To assess the potential impacts of the
hazardous waste regulations on used
CFC refrigerant recycling. EPA will
consider information on the universe of
used CFC refrigerant handlers (numbers
of facilities reclaiming, number of
faculties that use the CFC-11 and other
refrigerants and would be classified as
generators if the CFC refrigerants were
hazardous wastes, and how many
transporters there an currently). Finally,
EPA is soliciting comment on whether
the concerns can be redressed by
phased compliance rather than
exemption, and on whether alternative
approaches (such as streamlined
permitting, or reduced manifesting
requirements) could be used to reduce
any adverse recycling impact of RCRA
regulations.
Under RCRA, there is a requirement
to obtain • permit prior to beginning
construction of a new hazardous waste
management facility (if the facility did
not manage hazardous wastes prior to
the effective date of regulations for
those hazardous wastes—see 40 CFR
270.10(0). This requirement exists for
facilities that intend to treat ston. or
dispose of hazardous wastes from
generators other than conditionally
exempt small quantity generators. (In
the case of used CFC refrigerants, if
such facilities hadbegun storing and
reclaiming used CFC refrigerants prior
to September 25,1990. and met certain
other requirements, they would be able
to obtain "interim status" and would
have been able to continue storing and
reclaiming after September 25. However.
it appears that few parties were aware
of the TCs potential application to used
CFC refrigerants.) EPA believes that this
requirement may act as a deterrent to
firms contemplating entering the OKC
reclamation market after the effective
date of the TC rules. EPA notes that the
preceding discussion applies only to the
facilities actually conducting the
reclamation or reprocessing of the
refrigerants, and not to all refrigeration
equipment owners who have used
refrigerants that can be reclaimed.
In addition to potential requirements
on reclaimed refrigerants, other factors
may be influencing the reclamation/

satisfy nil environmental, health, and
safely concerns. For instance, a
premature selection of an alternative
that is less energy efficient would result
in increases in carbon dioxide and other
Hir pollutants which may cause
increases in global warming.
Recycling CFCs provides the
opportunity for industry to postpone or
even avoid entirely the need to retire
prematurely or retrofit equipment. The
Agency estimates that a recycling
program in the major air conditioning
and refrigeration sector*, fully
implemented by the early 1990's. could
rrsult in a net saving of over 159.000
metric tons of CFCs by the year 2000.
Complying with RCRA regulations may
increase venting of CFC refrigerants.
and thus increase the cost of the
Agency's CFC phaseout regulations. The
Agency discussed the potential for
increasing the costs of a recycling
program if there art: delays in its
implementation in an advance notice of
proposed rulemaking published on May
I. 1990 (55 FR 18256).
C. Environmental Concerns
In the ANPRM of May 1.1990 (55 FR
18250). the Agency described the human
health and environmental risks of CFCs.
An EPA analysis shows that chlorine
levels will continue to increase from
current levels of 3.0 to about 4.0 parts
per billion (ppb) despite • pha*»out in
production of controlled substances by
the year 2000. The Antarctic ozone hole
was discovered at chlorine levels of
approximately 2.5 ppb: natural chlorine
levels are .7 ppb. Earlier reductions in
CFCs before 2000 would reduce the
environmental risks (described below)
even as chlorine levels continue to
increase over the next decade.
The largest environmental impact
from emissions of CFC* come* from the
chlorine'* ability to deplete the ozone
layer, and thereby increasing the
amount of ultraviolet radiation reaching
the earth's surface. EPA believe* that an
increase in UV radiation will result In
increased death* from ikin cancer.
increased incidence of cataract*.
reduction in the function of the body'*
Immune system, and damage to crop*.
CFC* are also suspected greenhouse
gates
Recycling provide* an opportunity to
delay or reduce the increase in chlorine
level*. Indeed, estimates bated on
preliminary EPA analysis of a proposed
recycling program indicate that one-
third of all CFC* could be recycled by
the turn of the century. Recycling may
reduce the peak rale of chlorine loading
to the stratosphere.
The Agency is currently investigating
the impact that recycled CFCs may have
S-OSI9W QODXOONI2-FEB-4I IOI72U
on the ozone layer. Since these
chemicals are difficult to destroy, it is
likely that they will be eventually
released although at a later point in
time.* F.PA is investigating the impact of
their eventual release on peak chlorine
concentrations. Recent scientific
evidence suggests that a reduction of the
peak chlorine concentrations may more
than proportionally reduce ozone
depletion.1 It is likely that delayed or
reduced release of CFCs due to
recycling over the next 30 'o 40 years
will lower the peak of chlorine
concentration.
The Agency is promulgating today's
interim final rule with the belief that this
action will encourage used refrigerant
recycling. EPA is interested in hearing
from commenler* who have evidence on
the effect of this exemption. EPA is also
interested in evidence of harmful
environmental or health effects other
than those discussed in thin rulemaking.
Because EPA is attempting to balance
the potential environmental harm
caused by disruption to emerging
refrigerant recycling market* against the
potential environmental harm caused by
removing thit waiteitream from RCRA
subtitle C regulatory control. EPA is
asking for commenter* to provide any
available information to aid in
evaluating the human health and
environmental effect* of the*e action*.
D. Time Conside.vtiont
Of paramount concern to the Agency
it mitigating the potential for significant
advene health and environmental
impact*, a* discussed above, while
investigating these issues further. Under
the Clean Air Act amendment*, a
prohibition on venting mu*t become
effective by July 1.1982. Thus because of
the potential seriousness of the risk*
po*ed by CFC refrigerant venting. EPA.
believe* that Immediate action to
temporarily postpone the RCRA
regulation of the** material* pending
further Investigation 1* warranted to
mitigate the potential health and
environmental effect*. EPA is exercising
it* authority under the good cause

with potentially serious impacts on
stratospheric ozone levels that are
contrary to the public's best interest.
IV. Suspension of TC Requirements
A. Eligible Refrigerants
The refrigerant* that are eligible for
(hi* exemption are those
chlorofluorocarbons that are recycled
and that were used a* the heal transfer
fluid in a refrigeration cycle in totally
enclosed heat transfer equipment. These
chlorofluorocarbon* include CFC-11.
CFC-113, and the other
chlorofluorocarbon refrigerants.
including IICFC*. Example* of the
equipment in which these
chlorofluorocarbons may be used
include mobile air conditioning systems
(e.g.. those used in mass transit
vehicle*), mobile refrigeration
(refrigerated truck* and rail car*), and
commercial and industrial air
conditioning and refrigeration sytlem*.
The requirement* imposed by the TC are
suspended for such refrigerants by
today'* interim final action. The spent
CFC* that are being reclaimed will not
be regulated a* a Federal hazardous
waste a* a result of today's action
(unless a future determination to do *o,
I* made). Thui. the hazardous waste
regulatory requirement* for generator*.
transporter*, and recycler* of u*ed
chlorofluorocarbnn* that are being
reclaimed (discussed in lection II.R of
this notice) are suspended, effective
February 5.1981.
B. Rational* for Sutpttuion
A* a mult of the new information
provided In thi* notice, and to allow
adequate time lo collect additional data
and give careful consideration to all the
relevant liaue* and regulatory option*.
the Agency I* today promulgating an
Interim final rule that suspends the TC
rule for handler* of u*ed CFC
refrigerant* being recycled. Tt •
suspension will allow lime for
individual* to submit comments on the
various issues raised in this proposal,
and It will allow the Agency time to
consider all information concerning
lhe*e operation*. Had the Agency been
aware of this issue during the comment
period on the TC proposal, the Agency
would have carefully considered the
impact* and consequences of the TC
and determined the appropriate action
at thai time. Faced with new
information concerning the potential
adverse environmental impact* caused
by the TC. EPA weighed the benefits of
-------
5914 Federal Register / Vol 56VNo. 30 / Wedne«d«y,!,Febniaryvl3.U9» / Rules and Regulationa
the rule as applied to CFC refrigerants
against the potential public health
consequences of applying the rule to
CFC refrigerants in the interim while
EPA considers the new information, in
this case, due to the environmental and
health consequences from ozone
depletion. EPA believes that the public
interest may be better served by
suspending the rule to evaluate the
consequences. EPA solicits public
comment on its decision to suspend the
TC regulation for used CFC refrigerants
being reclaimed.
V. State Authorization
A. Applicability of Rules in Authorized
States
Under section 3006 of RCRA. EPA
may authorize qualified States to
administer and enforce the RCRA
program within the State. Following
authorization. EPA retains enforcement
authority under sections 3008,3013. and
7003 of RCRA. although authorized
States have primary enforcement
responsibility. The standards and
requirements for authorization are found
in 40 CFR part 271.
Prior to the Hazardous and Solid
Waste Amendments of 1964 (HSWA). a
State with final authorization
administered its hazardous waste
program in lieu of EPA administering the
Federal program in that State. The
Federal requirements no longer applied
in the authorized State, and EPA could
not issue permits for any facilities that
the State was authorized to permit.
When new, more stringent Federal
requirements were promulgated or
enacted, the State was obliged to enact
equivalent authority within specified
time frames. New Federal requirements
did not take effect in an authorized
State until the State adopted the
requirements as State law. In contrast
under RCRA section 3006(g) (42 U.S.C.
6826(g)), new requirements and
prohibitions imposed by HSWA take
effect in authorized States at the same
time that they take effect in
nonauthorized States. EPA is directed to
carry out these requirements and
prohibitions in authorized States,
including the issuance of permits, until
the State is granted authorization to do
so. While States must still adopt
HSWA-related provisions as State law
to retain final authorization. HSWA
applies in authorized States in die
interim.
B. Effect on State Authorizations
EPA considers this rule to be part of
the TC rule, and thus also a HSWA rule.
As a result EPA will implement the
provision* of today's rule in audiorized
States until their programs are modified
to adopt the final toxicity characteristic
and the modification is approved by
EPA. Implementation of today's rule
beyond the date of a State's receiving
final authorization for the toxicity
characteristic depends upon actions
taken by the State, as discussed below.
EPA will implement the provisions of
today's rule in unauthorized States.
Today's rule suspends the
requirements imposed in the final
Toxicity Characteristic regulation (see
55 FR11798, March 29,1990) for certain
CFC refrigerants being recycled. The
Toxicity Characteristic was
promulgated pursuant to a HSWA
provision and must be adopted by
States which intend to retain final
authorization. However, today's rule
provides for a standard which is
narrower in scope than would be
imposed in die final Toxicity
Characteristic for certain CFC
refrigerants which may fail the
characteristic and an recycled. In order
to promote recycling operations, today's
rule provides that these wastes would
not be hazardous wastes under the
Federal regulations, and States would
not be required to mandate their
management as such in order to retain
their RCRA authorization. However.
Section 3009 of RCRA provides that
States may impose requirements that
an broader in scope or more stringent
than those imposed under Federal
regulations. States, whether using RCRA
authorities (e.g\, authorities under State
law when States have received final
authorization to implement the toxidty
characteristic provisions in lieu of their
implementation by EPA), or other State
authorities under other statutes, may
impose hazardous waste requirements
on such operations, or may require other
more stringent conditions upon
management of these wastes.
VL Additional Information
A. Executive Order 12291—Regulatory
Impact*
Under Executive Order 12291, EPA
must determine whether a regulation is
"major." and therefore subject to the
requirement of a Regulatory Impact
Analysis. The overall effect of today's
rule would be to suspend requirements
imposed by the final Toxicity
Characteristic rule for certain CFC
refrigerant recycling operations. There
are no sampling or analysis
requirements in today's rule. The net
effect of this rule is to extend cost
savings to certain segments of the
potentially regulated community.
Consequently, no regulatory impact
analysis is required.
B. Regulatory Flexibility Act
Pursuant to the Regulatory Flexibility
Act 5 U.S.C. 601-612. whenever an
agency is required to publish a General
Notice of Rulemaking for any proposed
or final rule, it must prepare and make
available for public comment a
regulatory flexibility analysis that
describes the impact of the rule on small
entities (i.e., small businesses, small
organizations, and small governmental
jurisdictions). No regulatory flexibility
analysis is required, however, if the
head of the Agency certifies that the rule
will not have a significant impact on a
substantial number of small entities.
The suspension of the Toxicity
Characteristic requirements for certain
limited CFC recycling activities in this
rule is deregulatory in nature and thus
will only provide beneficial
opportunities for entities thatmay be
affected by the rule. Accordingly. 1
hereby certify that this regulation will.
not have a «ignifirant economic impact
on a substantial number of small
entities. This regulation, therefore, does
not require a regulatory flexibility
analysis.
C. Paperwork Reduction Act
Than are no reporting, notification, or
recordkeeping (information) provisions
in this rule. Such provisions* were they
included, would be submitted for
approval to the Office of Management
and Budget (OMB) under the Paperwork
Reduction Act 44 U.S.C. 3501 et seq.

RCRA REVISION CHECKLIST 85
Burning of Hazardous Waste in
Boilers and Industrial Furnaces
56 FR 7134-7240
February 21, 1991
(RCRA Cluster I, HSWA and non-HSWA provisions)
1) There are numerous typographical and technical errors in the final rule addressed by this checklist;
where they are obvious, we have noted them. On July 17, 1991 (56 FR 32688; Revision Checklist 94)
extensive corrections were made to the final rule addressed by this checklist because of the many
typographical and other errors found in the February 21, 1991 final rule. The Agency also published a
second technical correction on August 27, 1991 (56 FR 42504; Revision Checklist 96), which reversed the
revisions to 265.112(d)(2), 265.113(a) and 265.113(b) made by the final rule addressed by this present
checklist, which contains these revisions as published in that February 21, 1991 (56 FR 7134) final rule.
States are cautioned not to make the corrections to 265.112(d)(2), 265.113(a) and 265.113(b) as requested
by this checklist. Otherwise those corrections will have to be undone when Revision Checklist 96 is applied
for. Finally, Revision Checklists 111 (57 FR 38558; August 25, 1992) and 114 (57 FR 44999; September
30, 1992) made several technical amendments to the BIFs rule. Because of the extent of the technical
corrections made to the rule addressed by Revision Checklist 85, States are strongly encouraged to use the
Consolidated Boilers and Industrial Furnaces Checklist, which consolidates this present Boilers and Industrial
Furnaces rule with subsequent revisions made to it. A Consolidated Checklist which consolidates all final
BIFs rules through December 31, 1991 (i.e., Revision Checklists 85, 94, 96 and 98 (56 FR 33874;
September 5, 1991) is currently available on the SRPB Electronic Bulleting Board System. That
consolidated checklist will be part of SPA 12. The consolidated checklist will be updated as part of
subsequent SPAs as additional final rules addressing the BIFs rule are promulgated. For example, a
Consolidated Checklist which consolidates changes to the Federal code through June 30, 1993, including
Revision Checklists 85, 94, 96, 98, 105 (57 FR 27880; June 22, 1992), 111 (57 FR 38558; August 25,
1992) and 114 (57 FR 44999; September 30, 1992) will be developed as part of SPA 14.
2) States applying for Revision Checklist 85 are urged to adopt required Revision Checklists 94, 96, 111
and 114 changes at the same time the requirements addressed by Revision Checklist 85 are adopted.
States that have already adopted the provisions addressed by Revision Checklist 85 are strongly
encouraged to apply for the Revision Checklists 94, 96, 111, and 114 provisions as soon as possible.
3) Note that on September 5, 1991 (56 FR 43874; Revision Checklist 98), an administrative stay was
published affecting this final rule, by delaying when the permit standards become effective for coke ovens
burning certain hazardous wastes from a coke by-products recovery process. The changes addressed by
Revision Checklist 98 are optional. However, the final rule addressed by Revision Checklist 105 (June 22,
1992; 57 FR 27880) removed the September 5, 1991 administrative stay. Thus States should either not
adopt the administrative stay or, if they choose to adopt the stay, state in their regulations that this stay
ends on June 22, 1992.
4) The regulations addressed by this checklist typically do not make a distinction between the various types
of burning devices. However, the provisions in the regulations as they apply to sludge dryers, carbon
regeneration units, infrared incinerators, and plasma arc incinerators are non-HSWA requirements, while the
regulations as they apply to all other types of burning devices are HSWA provisions. EPA will implement
the HSWA requirements in authorized States until the States modify their programs and such modifications
are approved by EPA. The non-HSWA requirements are applicable only in those States that do not have
authorization. In authorized States, the non-HSWA requirements will not be applicable until States revise
their programs to adopt equivalent requirements under State law.

Burning of Hazardous Waste In Bolters and
Industrial Furnaces
AQINCY: Environmental Protection
Agency (EPA).
ACTION: Final rule.
SUMMARY: Under this final rule, the
Environmental Protection Agency (EPA)
is expanding controls on hazardous
waste combustion to regulate air
emissions from the burning of hazardous
waste in boilers and industrial furnaces.
Currently, such burning is exempt from
regulation. EPA is promulgating this
final rule after considering public
comment on rules proposed on May 6,
1987, plus the comments on EPA's
supplemental notices of October 26.1989
and April 27.1990.
These rules control emissions of toxic
organic compounds, toxic metals,
hydrogen chloride, chlorine gas, and
paniculate matter from boilers and
industrial furnaces burning hazardous
waste. In addition the rules subject
owners and operators of these devices
to the general facility standards
applicable to hazardous waste
treatment, storage, and disposal
facilities. Further, today's final rule
subjects hazardous waste storage units
at regulated burner facilities to part 264
permit standards. Burner storage
operations at existing facilities are
generally now subject only to interim
status standards under part 265.
Finally, today's rule takes final action
on two pending petitions for rulemaking:
(1) based on a petition by Dow Chemical
Company. EPA is designating halogen
acid furnaces as industrial furnaces
under § 260.10: and (2) based on a
petition by the American Iron and Steel
Institute, EPA is classifying coke and
coal tar fuels produced by recycling coal
tar decanter sludge, EPA Hazardous
Waste No. KO87, as products rather
than solid waste. The rule also makes
several technical corrections to
regulations dealing with loss of interim
status for facilities that achieved interim
status as of November 7,1984.
EFFECTIVE DATE This final rule is
effective on August 21.1991. Technical
corrections to 1270.73 are effective on
publication.
The incorporation by reference of
certain publications listed in the
regulations is approved by the Director
of the Federal Register as of August 21.
1991.
ADDRESSES: The official record for this
rulemaking is identified as Docket
Numbers F-87-BBFP-FFFFF and F-89-
BBSP-FFFFF. and is located in the EPA
RCRA Docket room 2427.401M Street
SW., Washington. DC 20460. The docket
is available for inspection from 9 a.m. to
4 p.m.. Monday through Friday, except
on Federal holidays. The public must
make an appointment to review docket
materials by calling (202) 475-4327. The
public may copy up to 100 pages from
the docket at no charge. Additional
copies cost $.15 per page.

EPA is planning to conduct six two-
day implementation workshops
beginning in mid February in the
following cities: San Francisco, CA;
Dallas. TX: Kansas City. KS; Atlanta,
GA: Chicago, IL; and Philadelphia. PA.
The purpose of the sessions is to explain
responsibilities of owner/operators
burning hazardous waste under this
rule. The first day will be open only to
government representatives involved in
implementation, compliance, and
enforcement of these regulations. The
second day is open to the public.
Preregistration is required to assure a
reservation. Same day registration will
be allowed as space is available.
Interested parties should call 919-549-
0722 to obtain further information and
get on the mailing list for notices.

Part Onr Background
I. Legal Authority
These regulations are promulgated
under authority of sections 1006, 2002,
3001 through 3007, 3010, and 7004 of the
Solid Waste Disposal Act of 1970, as
amended by the Resource Conservation
and Recovery Act of 1976, the Quiet
Communities Act of 1978, the Solid
Waste Disposal Act Amendments of
1980. and the Hazardous and Solid
Waste Amendments of 1984,42 U.S.C.
6905. 6912. 6921 through 6927, 6930. and
0974.
II. Overview of the Final Rule
A. Controls for Emissions of Organic
Compounds
Today's rule requires boilers And
industrial furnances to comply with the
same destruction and removal efficiency
(DRE) standard currently applicable to
hazardous waste incinerators: 99.9999%
DRE of dioxin-listed waste, and 99.99%
DRE for all other hazardous wastes. In
addition, the rule controls emissions of
products of incomplete combustion
(PICs) by limiting flue gas
concentrations of carbon monoxide
(CO), and'where applicable.
hydrocarbons (HC) to ensure that the
device is operated under good
combustion conditions. Finally.
emissions testing and health-risk
assessment is required for chlorinated
dioxins and furans for facilities meeting
specified criteria where the potential for
significant concentrations may exist.
B. Controls for Emissions of Toxic
Metals
The rules establish emission limits for
10 toxic metals listed in appendix VIII of
40 CFR part 261 based on projected
inhalation health risks to a hypothetical
maximum exposed individual (MEI). The
standards for the carcinogenic metals
(arsenic, beryllium, cadmium, and
chromium) limit the increased lifetime
cancer risk to the MEI to a maximum of
1 in 100.000. The risk from the four
carcinogens must be summed to ensure
that the combined risk is no greater than
1 in 100.000. The standards for the
noncarcinogenic metals (antimony.
barium, lead, mercury, silver, and
thallium) are based on Reference Doses
(RfDs) below which adverse health
effects have not been observed.
-------
.7338 Jdbmil &*&ti»T / Vol. 56. Wo. .35 ./ Thursday. Febiuary '21, 1991 / Roles *nd .-Regulations
The standards are implemented
through a three-tiered approach.
Compliance with any tier'is •acceptable.
The tiers are strutted -to allow-higher
emission rates (and feed rates) as-the
owner or operator elects to conduct
more site-specific testing and analyses
(e.g., emissions testmg,.dispersion
modeling). Thus, the feed rate limits
under each of the tiers are derived
based on differentdevels at.itte-opECific
inrbTmatioiLrekted:to:racility .design
and surrounding -terrain. Under Tier J,
the 'Agency has provided very
conservative-waste feed rate limits in
"reference" tables as a function of
effective stack height-and terrain and
land use in the vicinity of the stack and
assumed reasonable, worst-case
dispersion. The owner or operator
demonstrates compliance by waste
analysis, not emissions testing or
dispersion modeling. Consequently, 1he
Tier I feed rate limits are based on an
assumed reasonable, wont-case
dispersion scenario, and an assumption
that all metals fed to .the device are
emitted (Le., no partitioning to&ottom
ash or product and no removal by an air
pollution control «yatem (APCS)).
Under Tiflr.JI..the tjwnw or operator
conducts emissions testing {bul-nnt
dopanian-modeling) to.getrredit far
partitioning to-bottom aahiorpraduct
and APCB removal efficiency. Thus, the
Agency has developed conservative
emission rate limits in reference tables,
again as a function of effective stack
height and terrain and land use in the
vicinity of the stack. The Agency also
assumed reasonable, worst-case
dispersion-under Tier II.
Under Tter.nL.rhe owner OT operator
would conduct emissions testing and
site-specific dispersion modeling to
demonstrate that the actual (measured)
emissions do not exceed acceptable
levels considering actual (predicted)
dispersion.
The standards are implemented
through limits-on specified .operating
parameters, including hazardous waste
feed.tate and metals composition, ieed
rate of metals Irom all feed-Streams,
combustion chamber temperature, and
APCS-specific.parameters.
C. Controls for Emissions of Hydrogen
Chloride and Chlorine Gas
The rule* control emissions of
hydrogen chloride (HCl) and free
chlorine (Cl«) underthe same general
approach as that used formetals. The
owner and operator must comply with
and implement the HCl and Ck controls
in the same-manner as for metal*.
D. Emission Standards for Particulate
Matter
The ruleaiimit pazticulate:maiter (EM)
emissions of 0.08 gr/dscf. corrected to 7
percent oxygen (Ox). This is the same
standard-that currently applies to
hazardous waste incinerators and is
intended to supplement the risk-baaed
metals controls. (Metals emissions are
generally controlled by limiting feed
rates of metals and controlling PM.)
Compliance with the standard-is
demonstrated by emissions testing,-and
the standard is implemented ;by
operating bmrts m-the:permit -on
parameters including: ash content of
feed.streams, feed-rate of specific leed
streams, and air pollution control
system operating parameters. All boilers
and industrial furnacesmuatcomply
with the standard; inwever, cement and
aggregate kilns need not monitor the ash
feed rate of all feed-streams to
demonstrate compliance wim-the
standard given that paniculate matter
from these devices is generated
primarily from raw materials..Instead.
the rule provides that these device*
must comply with the operating limits
on the participate matter control system
to ensure continued operation at level*
achieved during the compliance test
(under-interim status) or-trial bum
(under the.parlB permit application).
E. Permitting Procedures
The final.rule requires similar
permitting procedures for regulated -Bffs
that apply to hazardous waste
incinerators. For example, owners and
operators are required to-submit* part B
permit application for evaluation in
order to be eligible-for an operating
permit Permit applications will be
called on a schedule considering .the
relative hazard to human health and
enviroment the facility poses compared
to other storage, treatment and disposal
facilities within the Director'* purview.
F. ControlJJuring Interim Status
Today's final rule requires boilers and
industrial furnaces-that have interim
status to comply with substantive
emissions controls for metals. HCL CU.
particulates, and CO (and. where
applicable. HC and dioxins and furans).
Owners and operators must certify
compliance with the emissions controls
under a prescribed schedule, establish
limits on prescribed operating
parameters, and operate within those
limits throughout interim status.
G. Units Exempt from Air Emissions
Standards
The rule conditionally exempts irom
regulation the following devices: (1)
Boilers and industrial himaae* that'burn
small quantities -of Hazardous -waste fuel)
(i.e., die small quantity burner
exemption), and,that operate the device
under prescribed conditions; (2)
smelting, melting, and refining Jurnaces
that process .-hazardous waste solely for
the purpose of metal reclamation and
not partially for destruction orenergy
recovery; and (3) coke ovens itthe only
hazardous waste they process is K087.
The small quantity:bumer
exemption—as provided in section
3004(q)(2)(B)—is « risk-based exemption
specifically-alluded to in the •statute. The
exemption is provided only to
hazardous waste fuels generated on-aite,
and is conditioned ana number .of
requirements, including a one-time
notification and recordkeeping.
The Agency is also providing a
temporary exemption for metal
reclamation -furnaces from today's
burner standards -until we determine
haw beat to apply rules designed lor
combusion process to noncombusion.
metal reclamation operation*..(It.should
be noted that section 3004(q) requires
EPA to issue niles controlling air
emissions from-devices burning

not apply to devices burning .hazatdouj
wast* for the «ole purpose of material '
lenovery. Although EPA has aumority to
issue suchTegulations, -the section
3004(q) deadline does not apply). To
distinguish between waste that are
processed solely for metal reclamation
rather than (partial) destruction, .the
final rule considered (.hazardous waste

refining furnace with a total
concentration of appendix VULipext 281

between processing for material
recovery and burning for energy
recovery, the.final rule considers*

reclamation furnace .with a -heating
value exceeding 5,000 Btu/lb to be
burned at least partially for energy
recovery. Metals reclamation furnaces
claiming the exemption must notify the
Agency, sample and analyze their
hazardous wastes to document
compliance with the condition* of the
exemption, and iceep .records of such
documentation.

rule if the only-hazardous -waste they

Federal RegUter / Vol. 56. No. 35 / Thursday, February 21. 1991 / Rules and Regulations 7137
other materials, it would be anomalous
to assert RCRA control over the coking
process.
H. Pollution Prevention Impacts
This rule provides an incentive to
reduce the generation of metal and
chlorine-bearing hazardous waste at the
source given that the metals and HC1
emissions controls will be implemented
by additional requirements attendant to
the disposal of those wastes, i.e.. feed
rate limits for individual metals and
total chlorine. These requirements are,
in essence, tied to the economics of
disposing of given volumes of waste
since feed rates depend, in part, on the
volume of waste the facility operator
needs to burn. Thus, the metals and HC1
controls do not simply require a percent
reduction in emissions, irrespective of
the volume and rate of incoming waste
streams. Rather, the controls are health-
based and, thus, provide limits on
emissions rates of metals and HG that
would be implemented by feed rate
limits.
Waste generators who send their
waste to industrial furnaces such as
cement kilns and light-weight aggregate
kilns that act as commercial waste
management facilities will have the
incentive to reduce the generation of
metal and chlorine-bearing wastes
because waste management fees are
likely to increase for such waste given
that the burner has a fixed metal and
chlorine feed rate allotment (due to
prescribed feed rates and facility
operating conditions). Wastes with
extremely high metals content may no
longer be acceptable for burning in
many cases unless the waste generator
reduces the metals content of the waste.
Any alternative for the disposal of such
wastes may be unavailable or the costs
of such treatment may be high enough to
create the incentive to reduce waste
generation rates at the source. This is a
typical scenario for pollution prevention
measures to be undertaken by waste
generators.
Similarly, generators who bum their
wastes on site also have the incentive to
reduce the generation of metal and
chlorine-bearing wastes given that the
rule will provide a fixed feed rate
allotment for their boiler or industrial
furnace.
IU. Relationship to Other Rules
A. Regulations to be Promulgated Under
the New Clean Air Act
Title in of the recent Clean Air Act
Amendments of 1990, amending section
112 of the Act dealing with hazardous
air pollutants, potentially addresses
many of the same sources that would be
regulated under today's rule. That
section requires the Agency to develop a
list of major and area sources of
hazardous air pollutants (a major source
is a stationary source that has the
potential to emit up to 10 tons per year
of a hazardous air pollutant, or 25 tons
per year of a combination of such
pollutants, and area sources are other
stationary sources emitting hazardous
air pollutants), and to develop
technology-based controls for such
sources over specified time periods. See
Clean Air Act amended sections 112(c),
and (d). Additional controls shall be
imposed within eight years after
promulgation of each of these
technology-based standards, if such
controls are needed to protect public
health with an ample margin of safety,
or to prevent adverse environmental
effect (Cost energy, and other relevant
factors must be considered in
determining whether regulation is
appropriate in the case of environmental
effects.) In addition, if the technology-
based standards for carcinogens do not
reduce the lifetime excess cancer risk
for the most exposed individual to less
than one a million (10-6), then EPA must
promulgate health-based standards. See
amended section 112(f)(2)(A).
It is premature for the Agency to
attempt to provide a definitive opinion '
on the relationship of these provisions to
today's rule. Sources covered by the
present rule may not ultimately be
required to be further regulated under
amended section 112, In this regard,
amended section 112(n)(7) provides that
if sources' air emissions are regulated
under subtitle C, "the Administrator
shall take into account any regulation*
of such emissions * * * and shall to the
maximum extent practicable and
consistent with the provisions of this
section, ensure that the requirements of
such subtitle and this section are
consistent" Thus, at a minimum,
Congress was concerned about the
potential for duplicative regulation and
urged the Agency to guard against it
Since the Agency regards today's rules
as protective (based on present
knowledge), it may be possible to avoid
further air emissions regulation. (EPA
notes, however, that these sources will
likely be listed as major sources, and the
Agency will study whether further
emissions controls are required in the
course of implementing amended section
112.)
B. April 27.1990 Proposed Incinerator
Amendments
On April 27.1990 (55 FR17862). EPA
proposed amendments to the existing
hazardous waste incinerator standard*
of subpart O. part 264 to make the
incinerator standards conform to the
emissions standards being promulgated
today for boilers and industrial furnaces
burning hazardous waste. The proposed
rule would add emission standards for
products of incomplete combustion (i.e..
carbon monoxide and hydrocarbon
limits), metals, and hydrogen chloride
and chlorine gas.
In the proposed rule for incinerators.
EPA also proposed to revise or to add
definitions for a number of thermal
treatment devices: Industrial furnace,
incinerator, plasma arc and infrared
incinerators. Those definitions are being
promulgated in today's rule. In addition,
EPA proposed in the incinerator
rulemaking to clarify the regulatory
status of carbon regeneration units.
Those clarifications are also
promulgated in today's final rule.
Finally, EPA proposed to revise the
definition of principal organic hazardous
constituents (POHCa) used to
demonstrate destruction and removal
efficiency (ORE). The revised definition
would allow the Director on a case-by-
case basis to approve as POHCs
compounds that are neither constituents
in the hazardous waste nor organic.
That revised definition of POHC is
finalized in today's rule as a part of the
ORE standard to control organic
emissions from boilers and industrial
furnaces.
C. July 18,1990 Proposed Amendment to
Definition of Wastewater Treatment
Unit to Exempt Sludge Dryers
On July 18,1990 (see 55 FR 29280),
EPA proposed to clarify the regulatory
status of sludge dryers to make it clear
that sludge dryers that meet the
definition of a tank and that were a part
of a wastewater treatment unit wen
exempt from RCRA regulation even if
they heretofore met the definition of an
incinerator. Today's final rule
promulgates a definition of sludge dryer
and revises the definition of incinerator
to explicitly exclude sludge dryers. See
Part Four, section II of today's preamble.
D. Land Disposal Restriction Standards
In the May 8,1987 proposal the
Agency indicated that once the present
rules became final the Agency would
amend certain of the land disposal
restriction standards that specified
incineration as • treatment standard (at
that time, the standard for HOCs under
the California list rule), to also include
burning in boilers and industrial
furnaces. See 52 FR at 17021. Since that
time, the issue has become more
involved. In particular, significant issues
regarding the relationship of the Bevill
amendment and land disposal
-------
JIM Federal RjgUter / Vol. 56. .No. .35 / Thursday. February .21. .1981 / Rules and Regulations
restrictions exist (which the Agency in

considering this issue). The Agency
believes it inappropriate to try and

The-Agency believes that
approximately 75 industrial furnaces
hum over one-million tons of hazardous
waste annually. The regulated universe
appears to comprise approximately 40
cementldlns. 18 light-weight aggregate
kilns. andlS halogen acid furnaces.
Each of these types of furnaces is
described.below.
A. Cement Kilns
Cement kilns are-horizontal inclined
rotating cylinders, refractory lined and
internally fired, to calcine a blend of
BOX limestone .and 20% shale to produce
Portland cement There ht a wet process
and a dry process for producing cement.

Dry kilns with a preheater or
precalciner often use.a by-pass duct to
remove from 5 to 30% of the kim off-
gases from the main. duct. The by-pass
gas is pa«sed;through a separate air
pollution control system to remove
particulate matter. By-pass.dust is not
reintroduced into the kiln system to
avoid a build-up of metal salts that can
affect product quality.
Some cement kilns .bum.hazaidous
waste fuels to replace.from 25 to.75% of
normal fossil fuels. Most kilns bum
liquid waate,fuals but several burn small
(e^:six«allon) containers of viscous or
solid hazardous\waste fuels-Containers
have been fired into the upper. -raw
material end of theMn and at the
midpoint of the kiln.
Several cement companies have also
expressed an interest in using solid

today'* rule, a facility may bum (or
proceis) hazardous watte solely as a
bona fide ingredient during interim
status beginning with the effective date
of the rule. If a waste is burned partially
for destruction or energy recovery,
however, it is not burned solely as an
ingredient and special restrictions apply
during interim status (see discussion
below). EPA considers a waste to be
burned at least partially for destruction
if it contains a total of 500 ppm or more
by weight of nonmetal hazardous
constituents listed in appendix VIII, part
261. Further. EPA considers a waste to
be burned at least partially for energy
recovery if it has a heating value of 5,000
Btu/lb or more.
Today's rule does not allow burning of
a waste for the purpose of destruction
during interim status prior to
certification of compliance (see
§ 266.103(c)) with all applicable
emission standards. Further, the rule
applies special requirements during
interim status on owners/operators who
feed hazardous waste into a kiln system
at any location other than the "hot" end
where product is discharged. Hazardous
waste burned (processed) solely as an
ingredient however, is not subject to the
special requirements because emissions
from such burning would not pose an
adverse effect on human health and the
environment*
B. Ught-Weight Aggregate Kilnt
Light-weight aggregate (LWA)
describes a special use aggregate with a
specific gravity much less than sand and
gravel which is used to produce
insulation and nonstructural and light-
weight concrete. LWA is produced much
like cement but the feedstocks are
special clays, pumice, scoria, shale, or
slate.
The LWA kiln is configured much like
a cement kiln. The raw material is
crushed and introduced at the upper end
of a rotary kiln. In passing through the
kiln, the materials reach temperatures of
1.900 to 2.100'F. Heat is provided by a
burner at the lower end of the kiln
where clinker is discharged.
LWA kilns are also major sources of
paniculate emissions and are equipped
with wet scrubbers, fabric filters, or
electrosatic precipitators. Wet scrubbers
dominated the industry until recently.
Many facilities are now converting to
dry systems to reduce the cost of residue

management by recycling the collected

LWA kilns that bum hazardous waste
fuel typically bum 100% liquid
hazardous waste fuels.
C. Halogen Acid Furnaces
The Dow Chemical Company (DOW)
filed a rulemaking petition with EPA on
March 31,1986, in accordance with the
provisions of 40 CFR 280.20, requesting
that EPA designate their halogen acid
furnaces (HAFs) as industrial furnaces.
HAFs are typically modified firetube
boilers that process secondary waste
streams containing 20 to 70 percent
chlorine or bromine to produce a
halogen acid product by scrubbing acid
from the combustion gases. Currently
HAFs that produce steam meet the
definition of a boiler while HAFs that do
not generate steam meet the definition
of an incinerator even though they use
hazardous waste as a fuel and as an
ingredient to produce halogen add
product Today's rule designates HAFs
that do not generate steam as an .
industrial furnace for the reasons given
below.
DOW petitioned the Agency to
designate their HAFs as industrial
furnaces after the Agency changed the
definition of incinerator in 1985 from a
"purpose of burning test" to a "design
test" and developed new classifications
for boilers and industrial furnaces. The
Agency inadvertently did not designate
HAFs as industrial furnaces at the time
which potentially left certain HAFs
operating not in compliance with the
incinerator standards promulgated in
1981. Although HAFs (prior to today's
rule) technically meet the definition of
incinerator, the Agency has indicated its
intention since receiving the DOW
petition to correct the problem and to
properly designate HAFs as industrial
furnaces.
On May 6.1987 (52 FR17033), EPA
proposed to grant this petition and to
add halogen acid furnaces (HAFs) to the
list of devices that are designated as
industrial furnaces under 40 CFR 260.10.
On April 27.1990 (55 FR 17917), the
Agency proposed changes to the
proposed designation of HAFs as
industrial furnaces. With modifications
based on additional information and
comments, today's rule adds HAFs to
the list of devices that are included in -
the definition of an industrial furnace
under 260.10.
In today's rule. EPA is defining an
"industrial furnace" in 260.10 as an
enclosed device that uses thermal
treatment to recover (or produce)
materials or energy as an integral
component of a manufacturing process.1
EPA has previously designated 11
devices as industrial furnaces: (1)
Cement kiln* (2) lime kilns: (3)
aggregate kilns (including light-weight
aggregate kilns and aggregate drying
kfini used in the asphaltic concrete
industry); (4) phosphate kirns; (5) coke
ovens; (6) blast furnaces; (7) smelting,
melting, and refining furnaces; (8)
titanium dioxide chloride process
oxidation reactors; (9) methane
reforming furnaces; (10) pulping liquor
recovery furnaces; and (11) combustion
devices used to recover sulfur values
from spent sulfuric acid.
The industrial furnace definition in
260.10 also provides criteria and
procedures for adding devices to the list.
A device may be defined as an
industrial furnace if it meets one or more
of the following criteria: (1) The device
is designed and used primarily to
recover material products: (2) the device
is used to bum or reduce raw materials
to make material products; (3) the device
is used to bum or reduce secondary
materials as effective substitutes for raw
materials in processes that use raw
materials as principal feedstocks; or (4)
the device is used to burn or reduce
secondary materials as ingredients in
industrial processes to manufacture
material products.
As explained below, the basis for
designating HAFs as industrial furnaces
under i 280.10 is that HAFs are integral
components of a manufacturing process.
they recover materials and energy, and
they meet two of the criteria (1 and 4)
described above for classifying a device
as an industrial furnace.
1. Current Practices
Information available to EPA
indicates that at least 3 companies in
the United States operate at least 30
devices that may be halogen acid
furnaces. These devices typically
process chlorinated or brominated
• secondary materials with 20 to 70
percent halogen content (by weight) to
produce an acid product either
hydrogen chloride (HC1) or hydrogen
bromide (HBr), both of which have e
halogen content that ranges from 3 to
• This definition of industrial furnace is the
revised definition aa noticed OB April V. 1980 (SS FR
17SSS). The previous definition read "an enclosed
device using controlled Oaaa oombMtion to recover

These secondary materials typically
hr.v-- as-fired heating values of
a.. ximately 9,000 Btu/lb and are
tyr Jly produced on site.
Some of the HAFs currently in use are
modified firetube boilers that generate
and export steam. These KAFs meet the
definition of a boiler under S 260.10. and.
thus, will be regulated as boilers. The
remaining HAFs. although modified
firetube boilers, do not generate steam
and thus do not meet EPA's definition of
a boiler. Today's rule classifies these
nonboiler HAFs as industrial furnaces.
For the remainder of this discussion, the
term "HAF" refers to these nonbciler
HAFs.
2. Designation of HAFs as Industrial
Furnaces
o. Dow's Petition. On March 31.1986,
the Dow Chemical Company (DOW)
filed a rulemaking petition with EPA in
accordance wilh the provisions of 40
CFR 260.20, requesting that HAFs at
Dow Chemical be designated as
industrial furnaces. EPA proposed to
grant this petition in the May 6,1987
proposal. Today's rule includes HAFs in
the definition of an industrial furnace
under § 260.10. Further background
discussion on DOW's petition is
contained in the May 6,1987 proposed
rule.
b. May 1987 and April 1990 Proposed
Rules. EPA proposed to designate HAFs
as industrial furnaces for the reasons
discussed in the May 6,1987 proposed
rule. To ensure that a particular device
was an industrial furnace involved in
bonafide production of acid * as an
integral component of a manufacturing
process, and was not an incinerator
equipped with hologen emissions
removal devices, the 1987 proposed HAF
definition required that: (1) The furnace
by located on site at a chemical
production facility; (2) the waste fed to
the device be halogenated: and (3) the
acid product from the device contain at
least 6 percent halogen acid.
Based on comments received on the
1987 proposal and on further
consideration by the Agency, EPA
proposed revisions to the HAF definition
in the April 1990 notice. These revisions
were proposed for two reasons: (1) To

better clarify the differences between
HAFs and incinerators equipped with
wet scrubbers to control halogen acid
emissions, and (2) to better reflect
industry practice.
To ensure that a particular device is
an integral component of a chemical
manufacturing process, the April 1990
proposal included requirements that at
least SO percent of the acid product be
used on site and that any off-site waste
fed to '.he HAF be generated by a SIC
2C1 (inorganic chemicals) or SIC 286
(organic chemicals) process. To ensure
that the waste is burned as a bona fide
ingredient to produce the halogen acid
product, the April 1990 proposal also
required that each waste fed to the HAF
have an "as-generated" halogen content
of at least 20 percent. In addition, to
better reflect industry practice, the 1990
proposal required that the acid product
have a halogen acid content of 3 percent
rather than 6 percent, an amount that
still clearly distinguished the HAF acid
product from incinerator scrubber water,
which has an acid content of well below
1 percent. Finally, EPA proposed in
April 1990 to list hazardous waste fed to
a HAF as inherently waste-like to
ensure that halogenated waste fed to a
HAF (and the HAF itself) would be
subject to regulation. This would
preclude a claim that the secondary
materials were used as ingredients to
make a product, and, thus, not a solid
waste under { 261.2(e)(l)(i).
c. Summary of Public Comments.
Commenters on the 1987 and 1990
proposed rules objected to the
requirements that 50 percent of the acid
product be used on site and that any off-
site waste feed be limited to SIC 281 or
286 processes. The commenters argued
that minimum specifications on the
halogen content of the feed and/or the
acid content of the HAF product are
sufficient to distinguish bonafide HAF
operations from incinerator operations.
and that the requirement that a
substantial portion of the product be
used on site serves only to limit the
legitimate treatment of halogenated
wastes and the sale of bona fide HAF
products without being necessary to
protect human health and the
environment
After consideration of these
commenters' concerns, the Agency
believes that both the proposed off-site
restriction for waste fed to HAFs and
the proposed on-site acid product use
restriction are indeed unnecessary to
ensure that HAFs are integral
components of manufacturing processes.
The Agency agrees with the commenters
that the requirements specifying the
minimum halogen content of the watte
feed and the minimum halogen acid
concentration of the HAF product are
sufficient to ensure that HAFs are
integral components of a manufacturing
process (i.e., the process of halogen acid
production). EPA is not adopting these
proposed conditions given that air
emissions from HAFs will be regulated
under today's rule, that these proposed
conditions were directed at how to
classify these devices rather than how
to ensure their safe operation, and that
HAF operations (as properly controlled)
are environmentally advantageous in
that they utilize acid values rather than
dispose them and therefore should not
needlessly be discouraged. Today's rule.
therefore, does not restrict the use of
HAF waste feeds generated off site or
require that any percentage of the acid
product be used on site.
In today's rule, the Agency considers
a bona fide HAF operation as one in
which a secondary material with a
minimum as-generated halogen content
of 20 percent by weight is processed into
an acid product with a minimum
halogen content of 3 percent by weight.
The acid product must be used in a
manufacturing process either on site or
off site. The Agency maintains that this
approach will allow the legitimate
processing of highly halogenated
secondary materials into usable
products but will still clearly distinguis
HAF product acid from incinerator
halogen acid scrubber water.
Upon review of other comments
submitted on the 1987 and 1990
proposed rules, the Agency has
identified several issues pertaining to
HAFs that require clarification in the
regulations. Specifically, these issues
concern: (1) The regulation of chlorine
emissions from HAFs. (2) the operation -
of HAFs under the special operating
requirements (SOR) exemption for
boilers, and (3) the designation of
hazardous waste fed to HAFs as
inherently waste-like material.
One commenter to the 1987 proposed
rule requested that the Agency clarify its
position on limiting inorganic halide
salts in feedstocks to boilers and
industrial furnaces. The Agency has
established limits on emissions of HCI
and Cli from industrial furnaces, and a
HAF operator, like any other industrial
furnace operator, must comply with
these HCI and Cb emission standards.
To demonstrate compliance under the
Tier I feed rate screening limits, a HAF
operator must include inorganic chlorine
as part of the total chlorine fed to the
device. The Agency believes that this
requirement is justified because recenj
testing indicates that even thermally 1
stable compounds such as NaCl are
-------
Federal Register / Vol. 56, No. 35 / Thursday, February 21, 1991 / Rules and Regulations 7141
converted with high efficiency to HC1
under laboratory conditions that
simulate incineration.'
Another commentex to the 1987
proposal stated that HAFs are unjustly
excluded from the automatic waiver of a
trial burn to demonstrate 99.99%
destruction and removal efficiency
(ORE) when operated under the special
operating requirements (SORs). The
Agency acknowledges the commenter's
concern, but notes that all industrial
furnaces, including HAFs, are ineligible
for the automatic ORE trial bum waiver.
The Agency stated in the preamble to
the 1987 proposal that modified boilers
that produce and export steam (and thus
meet EPA's definition of boiler in
§ 260.10) would be regulated as boilers.
In such a case, the unit may be eligible
for the automatic waiver of the ORE trial
bum, which applies only to boilers. Any
halogen acid furnace that is a modified
fire-tube boiler not meeting the
definition of a boiler in 1260.10.
however, would not be eligible for the
automatic waiver. The Agency's reasons
for applying the automatic ORE trial
'jura waiver only to boilers are
discussed further in Section II.C.2.d of
this preamble.
Several commenters expressed
concern that the April 27,1990 proposal
required a minimum heating value of
5,000 Btu/lb for secondary materials fed
to HAFs. Today's final rule does not
require a minimum heating value on
secondary materials fed to HAFs.
Although the Agency understands that
most wastes burned in HAFs have a
heating value greater than 5,000 Btu/lb
and. so. that HAFs are engaged in
energy recovery as well as materials
recovery, not all wastes meeting the
minimum halogen limit also have a
heating value normally associated with
energy recovery. The Agency believes
that HAFs need not be required to
recover both material and energy values
from every hazardous waste fed to the
device to meet the definition of an
industrial furnace, and that the
regulations adopted today for HAFs
ensure that they will be operated in a
protective manner even if energy values
are not recovered.
Commenter's misconceptions
regarding a minimum heating value for
secondary materials may have arisen
from the Agency's proposal pursuant to
§ 261.2(d)(2) to list hazardous waste fed
to HAFs as inherently waste-like
material. In today's rule, the Agency is
listing as inherently waste-like any
secondary material fed to HAFs that is
* U.S-EFA. Laboratory Method to Eatlmtte

IncintrtUoo of • Wutt. Ftbruuy ItBO.
identified or listed as a hazardous waste
under 40 CFR part 261. subparts C and
D. Without such materials being
designated as inherently waste-like,
HAFs burning hazardous wastes solely
as ingredients (i.e., wastes that have low
heating value and therefore, are not
burned partially for energy recovery) to
produce an acid product might not be
regulated because the material they are
burning might not be a solid waste
pursuant to }261-2(e)(l)(i). However.
HAFs that burn hazardous wastes with
high heating values (i.e.. greater than
5.000 Btu/lb). would be subject to
today's rule even without listing them as
inherently waste-like because these
wastes are considered under
S 261.2(e)(2)(ii) to be burned et least
partially for energy recovery. For
reasons discussed in the April 27.1990
proposed rule (55 FR17892), the Agency
believes that such an inconsistent result
would not provide adequate protection
of human health and the environment
(the wastes burned by HAFs are some
of the most toxic generated and
regulation of emissions from burning
these wastes certainly is needed to
protect human health and the
environment). Moreover, there are
significant elements of treatment
associated with burning in HAFs: toxic
organic compounds are destroyed rather
than recovered, and the burning if
conducted improperly could become
part of the waste disposal problem.
Because the materials burned in HAFs
meet the criteria of 12812(d) for
inherently waste-likely materials, EPA
today is adding to the list of inherently
waste-like materials under 1261.(d)(2)
secondary materials fed to HAFs that
are listed or identified as hazardous
waste under subparts C or D of part 261.
While HAFs will not be precluded from
burning secondary materials with low
heating values, today's listing will
prevent the HAFs that burn this material
and the material itself from being
unregulated. As a result in all cases,
hazardous waste fed to HAFs, and the
HAFs themselves, will be subject to
hazardous waste regulations under
today's final rule.
d. Basis for Designating HAFs as
Industrial Furnaces. EPA has defined an
industrial furnace in 1260.10 as any of
the specifically-designated enclosed
devices that are integral components of
a manufacturing process and that use
thermal treatment to accomplish
recovery of materials or energy. To date.
11 types of devices have been
designated as industrial furnaces. The
industrial furnace definition also
provides criteria for adding devices to
the list As discussed above, these
criteria include: (1) The design and use
of the device primarily to accomplish
recovery of material products; (2) the
use of the device to burn or reduce raw
materials to make a material product (3)
the use of the device to burn or reduce
secondary materials as effective
substitutes for raw materials in
processes using raw materials as
principal feedstocks; and (4) the use of
the device to bum or reduce secondary
materials as ingredients in an industrial
process to make a material product. As
explained below, HAFs, meet the
definition of an industrial furnace as
well as two of the above criteria, (1) and
(4), for designating additional devices as
industrial furnaces.
HAFi an Integral Components of a
Manufacturing Process. HAFs are
commonly located on-site at large scale
chemical manufacturing processes that
reclaim primarily secondary materials
generated on-«ite and that typically use
the halogen acid product on-site. In
these cases, the Agency believes the
device should clearly be considered an
integral component of the manufacturing
process and. thus, eligible for
designation as an industrial furnace.
The situation is less clear when the
device receives halogen-bearing
secondary materials from off-site or if
the halogen acid product is sent off-site.
In these situations, the Agency believes,
nonetheless, that the device should be
considered an integral component of a
manufacturing process and. thus.
eligible for consideration as an
industrial furnace provided that the
device is located on the site of a
manufacturing process and that the
halogen acid product is used by a
manufacturing process.
HAFs Recover Material* and Energy.
EPA believes that HAFs recover
materials and energy to produce a bona
fide product Production of halogen acid
(a 3 to 20 percent halogen acid solution)
from the combustion of chlorine-bearing
secondary materials constitutes
materials recovery in the context of the .
designation of HAFs as industrial
furnaces. HAFs can also be considered
to bum secondary material as
ingredients in an industrial process to
make a material product (i.e.. the
product halogen acid). As discussed
above, chlorine-bearing secondary
materials an burned to produce the
halogen add product for nee in a
manufacturing operation.
HAFs alto recover energy. Moat
halogen-bearing secondary materials
reclaimed in HAFs are burned partially
for energy recovery because substantial.
usable heat energy is released by the
materials during combustion. The

industrial furnace need not involve any
export of energy. Rather, energy
recovery in an industrial furnace is
based on the burning of materials with
substantial heating values (greater than
5.000 Btu/lb) in a manner that results in
the release of substantial usable heat
energy. See 50 FR 49171-49174
(November 29.1985).8
HAFs Meet Industrial Furnace
Criteria. The Agency beleives that
HAFs meet two of the above criteria
(i.e., criteria (1) and (4)) for designating
devices as industrial furnaces. EPA
believes that restrictions on the halogen
content of waste streams fed to HAFs
and on the halogen content of the acid
product ensure that the HAF is: (a)
Designed primarily to recover halogen
acid (and so is not engaged in
incineration); and (b) used to burn
secondary materials as ingredients in
the process of halogen acid production
to produce a material product (i.e., the
product halogen acid).
Addition of HAFs to List of Industrial
Furnaces. EPA believes that HAFs are
integral components of a manufacturing
process and that they are designed and
operated to recover materials and
energy. For these reasons EPA is today
adding to the list of devices designated
as industrial furnaces under J 260.10
HAFs defined as furnaces that: (1) Are
located at the site of a manufacturing
process; and (2) process hazardous
wastes with a minimum as-generated
halogen content of 20 percent by weight
to produce an acid product with a
minimum halogen content of 3 percent
by weight and where the acid product is
used in a manufacturing process.
e Interim Status for HAFs. HAFs that
are in existence on the effective date of
today's rule are eligible for interim
status like other boilers and industrial
furnaces burning for energy or material
recovery. Although certain HAFs may
technically have met the amended
definition of incinerator, EPA believes
that there was legitimate confusion as to
such unit's operating status. These
devices would not have been
incinerators under the original 1980
* Wt note •• discussed previously In the text that

definition of incinerator because their
primary purpose was not destruction of
waste. When EPA amended that
definition in 1985 to adopt a definition
based on the unit's design rather than its
operating purpose, the Agency did not
intend to regulate HAFs as incinerators
and noted that the regulatory change
was not intended to (or expected to)
affect the number and identity of
regulated incinerator units. See 50 FR
625 (Jan. 4,1985). Moreover, given that
many HAFs met the definition of boiler,
it would have been anomalous and
unintended for some HAFs to be subject
to full regulation and others to be
unregulated (until the present rules were
adopted). Given these circumstances,
the Agency is rinding pursuant to
§ 270.10(e)(2) that there was substantial
confusion as to which HAF owners and
operators were required to submit a part
A application and that this confusion is
attributable to ambiguities in the subtitle
C rules. Accordingly, such owners and
operators may submit part A
applications by the effective date of
today's regulation.
We note that this policy on interim
status eligibility date does not apply to
other devices that are currently subject
to regulation as an incinerator but claim
to be an industrial furnace subject to the
BIF rule and its interim status eligibility
date. An example is an aggregate kiln
that currently burns hazardous waste
for the purpose of treatment
(destruction) and. so, is subject to the
incinerator standards of subpart O.
parts 264 and 265. There is no ambiguity
about the regulatory status of such a
device given that the Agency clearly
intended for such burning to be subject
to the incinerator standards, and the
Agency's rules have always so stated.
Thus, the date for interim status
eligibility for such facilities is the 1981
date for incinerator interim status.
D. Smelting. Melting, and Refining
Furnaces Burning Hazardous Waste to
Recover Metals
In the October 1989 supplement to the
proposed rule, EPA solicited further
comment on an appropriate regulatory
regime for smelting furnaces burning
hazardous waste for the exclusive
purpose of material recovery. See 54 FR
43733. This issue was closely connected
with the question of jurisdictional
limitations on the Agency's authority to
regulate industrial furnaces burning
secondary materials for material
recovery, discussed under the rubric of
indigenous wastes. Id. at 43731-32. The
Agency noted generally that where it
did not perceive jurisdictional
limitations on its authority, it regarded
regulation of organic emissions from
smelting furnaces as unnecessary given
the normal absence of organics in the
material fed to the unit We also
indicated concern at the prospect of
regulating emissions of metals that were
hot attributable to the processing of
hazardous waste, and accordingly
solicited comment as to a means of
determining when burning of hazardous
waste resulted in emissions in excess of
those from processing other materials in
the device. Id. at 43733. With respect to
a test for determining-when wastes are
indigenous, the Agency reproposed a
fairly broad test that would have had
the effect of excluding many wastes and
devices from the Agency1.! jurisdiction,
but would have distinguished between
wastes being burned for the purpose of
conventional treatment, and for the
purpose of material recovery treatment.
These proposals proved extremely
controversial. Perhaps more importantly,
after the proposal was issued, the
question of indigenous waste was the
partial subject of the District of
Columbia Circuit Court of Appeals'
decision API v. EPA. 906 F. 2d 728 (DtC.
Cir. 1990). In that decision, the court
stated that the Agency had been overly
restrictive in interpreting the
jurisdictional limitations imposed by the
statutory definition of solid waste based
upon the court's earlier opinion in
American Mining Congress v. EPA, 8241
F. 2d 1177 (D.C. Cir. 1987). That earlier
opinion, the court held, is limited to
situations involving continuous
recycling processes that are not part of
the waste disposal problem, and
certainly does not mandate the type of

and directed the Agency to rethink
whether any type of indigenous

The court's opinion, as well as the
many comments on this issue, raise
complex issues that EPA has not yet
resolved. (In this regard, the Agency

apply to devices burning for the purpose
of material recovery. H. Rep. No. 198,
98th Cong.. 1st Sess. 40. and so the
court-ordered December 31.1990
issuance date does not apply.) In
particular, the Agency is presently
studying the question of jurisdiction as
part of a comprehensive effort to
determine if the Agency's rules on
recycling should be amended (either as
a regulatory matter or as part of RCRA
reauthorization). In the interim.
however, the Agency does not believe it
prudent to apply regulations to a whole
potential class of devices and wastes
that the Agency has not fully evaluated
(since these situations would have been
excluded from regulation under the
proposal). See provision for conditional
deferral of smelting, melting, and
refining furnaces under { 266.100(c). In
addition, because EPA has placed most
of its efforts into issuing the mandated
portion of these regulations as soon as
possible, the Agency has not resolved
the questions of how to regulate raised
in the 1989 notice even for the class of
smelting furnaces where authority
would have existed under the proposed
view of indigenous waste. The issue of
whether material recovery is a form of
"treatment" is also presently submitted
for decision to a panel of the DC Circuit
in Shell Oil v. EPA (No. 80-1532). and
the Agency believes it prudent to await
the court's ruling.
Another reason for deferring
regulation of these devices is that the
Agency wishes to study further whether
regulation under the Clean Air Act may
be more appropriate than RCRA
regulation. Smelting, melting, and
refining furnaces have been traditional
subjects of Clean Air Act regulation.
and with the advent of amended section
112 of the Clean Air Act Amendments of
1990, technology-based controls on toxic
air emissions are likely to apply to these
devices. Given that in many instances
the principal risks potentially posed by
air emissions from these devices would
come from the nonhazardous waste
portion of feed (see 54 FR at 43733). and
that Clean Air Act regulation may result
in control of individual toxics, the
Agency believe* that further study of the
most appropriate means of regulation is
warranted. (The Agency specifically
requests information on other devices
that may bum hazardous waste solely
for metal recovery. EPA will use such
information to consider whether the
deferral for smelting, melting, and
refining furnaces should be broadened
provided that the principles stated here
apply to the other devices as well.)
At the same time, EPA is concerned
that this deferral not become a license
for sham recycling activities, or for
operations motivated by conventional
treatment objectives rather than
recovery purposes. Accordingly, the
Agency has crafted this deferral
narrowly. First only smelting, melting,
and refining furnaces (as used in the
§ 280.10 definition of "industrial
furnace") burning hazardous waste
solely to recover metals would be
eligible for this deferral. In the unlikely
event that one of these devices would be
used to recover organics or nonmetal
inorganics. EPA believes that
substantial amounts of organics would
be destroyed showing that the purpose
of the activity was either conventional
treatment or energy recovery. (The
Agency notes specifically that it intends
to include as a smelting, melting, or
recovery furnace the types of high
temperature metal recovery devices
used as the basis for the land disposal
prohibition treatment standard for
waste KO61. and other similar devices.)
Second, sham recovery operations
would be viewed as conventional
treatment operations and would require
a permit to control emissions. Although
it is difficult to quantify When
operations are sham, two fundamental
notions are that any waste involved
must contain economically viable
amounts of metals to recover (the best
objective measure would be the same or
greater levels of metal as in normal
nonhazardous feed stocks), and that the
person recovering the metal be in the
business of producing metals for public
sale (whether to an ultimate user or for
further processing or manufacture). See
also S3 FR at 522 (Jan. 8.1988). The
limitations on Btu level and levels on
toxic organics discussed below are
further efforts to ensure that only bona
fide metal recovery activities be
deferred from emissions regulation at
this time.
Third, today's regulations are deferred
only when these devices bum (process)
hazardous waste exclusively for metal
recovery and not partially for
destruction or energy recovery as well.
To implement this policy, today's rule
provides that a waste with • heating
value of 5.000 Btu/lb or more (either as-
generated or as-fired) is burned (at least
partially) as a fuel. The heating value
limit is based on the Agency's long
standing sham recycling policy (48 FR
11157 (March 18,1983)) that wastes with
a heating value of 5.000 Btu/lb or more
are considered to be fuels. See also 50
FR at 49171-173 (Nov. 29.1985) (partial
burning for energy recovery is covered
by section 3004(q) and Btu-rich wastes
are burned at least partially for that
purpose).
Finally, only wastes that contain less
than 500 ppm total toxic organic
constituents listed in appendix VIII. part
261, will be considered to recover
metals. EPA believes that it is important
to have an objective measure to
determine when burning is for metal
recovery, and that a 500 ppm level is
within the zone of reasonable values
that the Agency could select for this
purpose. As noted in the supplemental
proposal in a closely related context, a
500 ppm level for total toxic organic
constituents reasonably distinguishes
wastes destined for material recovery
from wastes burned for nonrecovery
purposes because: (1) It represents a
concentration of material far exceeding
trace levels (generally measured in
single digit parts per million (ppm) or
tens of ppm); (2) this level of hazardous
constituents could create an incremental
health risk if burned inefficiently, or
with inadequate emission controls; and
(3) this level is high enough to indicate
that an objective of burning is waste
treatment—destroying nontrace level
organics—as opposed to material
recovery. (The Agency's earlier proposal
dealt with the question of when a waste
might be considered to be indigenous to
an industrial furnace burning for
material recovery, and considered the
issue of whether these devices were
burning for a material recovery purpose,
and proposed the 500 ppm level adopted
in this rule as a means of objectively
ascertaining that purpose. 54 FR 43731.)
In order to be informed of persons
claiming this deferral, and in order to
decrease potential abuse of the deferral.
the Agency is requiring that all persons
notify the Agency if they assert that
their smelting, melting, or refining
furnaces are deferred from regulation
when burning hazardous wastes
because the purpose of the activity is
metal recovery. In addition, all such
persons have to keep records
documenting the basis for the claim (i.e..
that the wastes meet the Btu and total
toxic organic constituent thresholds, the
wastes contain recoverable levels of
metals, and the device is indeed
engaged in producing a metal product
for public use). Sampling and analysis
procedures specified in SW-846 must be
used to make these determinations.
These conditions are consistent with
existing I 281.2(f) which requires that all
persons claiming to be exempt or
excluded from regulation because of a
recycling activity to have the burden of
proof demonstrating that they are
entitled to the exemption or exclusion.
In addition, the Agency notes that a
consistent recommendation of state and
regional officials at the Agency's recent

standard for MWls also served as a
^surrogate to control emissions of toxic
petals. 54 FR 52219. In contrast today's
rule has separate emission standards for
each toxic metal.) We are not prepared
to do that at this time, however, because
we have not conducted the studies to
establish an appropriate PM standard
that represents best demonstrated
technology (BUT). Although many
boilers and industrial furnaces may be
able to achieve a PM standard lower
than 0.08 gr/dscf (in fact the PM NSPS
for specific types of BBFs is lower than
0.08 gr/dscf), we are not certain that all
BIFs can meet a standard of 0.015 gr/
dscf. This is because some industrial
furnaces have a very high (uncontrolled)
particulate loading due to entrained
particles of raw materials. Examples are
cement kilns and light-weight aggregate
. kilns. Hence, a single PM standard of
0.015 gr/dscf cannot now be
promulgated.
The Agency firmly believes that the
0.08 gr/dscf PM standard, when used as
a supplement to the risk-based metal
controls provided by today's rule,
provides protection of human health and
the environment Given that hazardous
waste burned in BIFs could contain
virtually unlimited concentrations of
toxic metals, the Agency believes that
Iriak-based standards are needed to
supplement the PM standard for
hazardous waste burning irrespective of
whether the PM standard represents
best-demonstrated technology. Even
under a PM standard as low as 0.015
gr/dscf, a large fraction of the PM
emitted from a hazardous waste
combustion device could be comprised
of toxic metals that could result in
substantial health risk.
Nonetheless, the Agency will consider
if additional PM controls are warranted
to control emissions of toxic metals. In
that evaluation, the Agency will
consider whether the additional
controls, if any, should be promulgated
in the future under the new Clean Air
Act See discussion in section IILA of
part One of this preamble. Finally, we
note that permit writers also could
impose a lower PM standard where
facts warrant pursuant to the omnibus
permit authority in section 3005(c)(3).»

A. Basis for Final Rule
Particulate matter (PM) is controlled
from combustion sources to limit
emissions of toxic metals and PM per se
(i.e.. because of human health and
ecological impacts associated with PM
that does not contain toxic metals). In
the May 6,1987 proposed rule, EPA
suggested that a PM emission standard
was not needed for boilers and
industrial furnaces because the risk-
based metals controls provide adequate
control of metals emissions. The Agency
reasoned that a standard intended to
control PM per se would be more
appropriately applied to these sources
under authority of the Clean Air Act
rather than RCRA.
EPA received numerous comments on
the May 8,1987 proposed rule suggesting
the need for a particulate standard for
boilers and furnaces burning hazardous
waste. Many commenters believed that
notwithstanding the risk-based metals
controls, unregulated PM emissions with
adsorbed toxic metals and organic
compounds could pose a significant
heath risk. In addition, three
commenters suggested that EPA address
the issue of particulate control during
soot-blowing cycles when levels of
particulate emissions are 4 to 7.2 times
the level of emissions under normal
operation. The Agency carefully
considered these comments and
subsequently determined that the risk-
based metals standards should be
supplemented with a PM standard to
provide a common measure of control
for metals. This decision was based in
part on a consideration of commenters'
concerns about the limitations of risk-
based metals standards. See 54 FR
43720-21. Hence, the Agency
subsequently proposed a particulate
emissions standard of 0.08 gr/dscf
(grains/dry standard cubic foot)
corrected to 7% oxygen in the October
26.1989 supplement to the proposed
rule. The standard would be applicable
to all boilers and industrial furnaces not
governed by a more stringent (NSPS or
SIP) standard.
1. Alternatives Considered. In
selecting the standard for boilers and
industrial furnaces, the Agency
considered the following alternatives:
(1) Apply the current NSPS standard for
steam generators burning waste: (2)
apply the applicable NSPS: or (3) apply
the existing hazardous waste incinerator
standard. These options are discussed in
the 1989 supplemental notice (54 FR
43720).
Many commenters supported the
proposed particulate standard of 0.08
gr/dscf. Several commenters, however,
opposed this limit arguing against
imposing a standard appropriate for
incinerators on boilers and furnaces.
Still other commenters suggested mat
the 0.08 gr/dscf limit did not go far
enough in protecting the public health.
These respondents argued for a lower
limit comparable to that the Agency
proposed for municipal waste
incinerators.
The Agency continues to believe that
the 0.08 gr/dscf PM standard, when used
as a supplement to the risk-based metal
controls provided by today's rule,
provides substantial protection of
human health and the environment
2. Basis for Standard. Today's rule
promulgates the proposed particulate
emission limit of 0.08 gr/dscf because,
as a supplement to the risk-based metals
controls, it provides a common measure
of protection from particulate emissions
from boilers, industrial furnaces, and
incinerators burning hazardous waste.
In addition to providing control of
particulate metals and adsorbed organic
compounds, the 0.08 gr/dscf standard
should also ensure that the Clean Air
Act's National Ambient Air Quality
Standard (NAAQS) for particulates is
achieved in most cases. An analysis of
existing sites shows that emissions of
particulates at 0.08 gr/dscf could result
in MEI levels of up to 30% of the
maximum daily PM«o (particulate matter
under 10 microns) NAAQS (150 mg/m*).
If background particulate levels at a site
are high (i.e., the site is in a attainment
area), particulate emissions from the
device should also be addressed as part
of the State Implementation Plan (SIP)
(as they are now for hazardous waste
incinerators in particulate non-
attainment areas). Therefore, although
the 0.08 gr/dscf standard may not
ensure compliance with the NAAQS in
every situation, this issue will be
addressed by the SIP since the facility
would be. by definition, in a non-
attainment area for particulate
emissions.
B. Interim Status Compliance
Procedures
Facilities operating under interim
status must comply with the PM
emission standard. By the effective date
of the rule, owners/operators must
submit a certification of precompliance
that documents their use of engineering
judgment to show that considering feed
rates of ash from all feed streams,
partitioning of ash to bottom ash or
product and the PM removal efficiency
of the air pollution control system
(APCS), PM emissions are not likely to
exceed the 0.06 gr/dscf limit Owners
and operators must also establish and
provide with the precompliance

0. Controls for Emission* of Toxfe
Organic Compounds
Burning hazardous waste that
contains toxic organic compounds (Le.,
organic compounds listed in appendix
Vm of 40 CFR part 261) under poor
combustion conditions can result in
substantial emissions of the toxic
compounds originally present in the
waste as well a* other compounds, due
to partial but incomplete combustion of
the constituents in the waste. The
quantity of toxic organic compounds
emitted depends on the concentration*
of the toxic compounds in the waste, the
waste firing rate (i.e.. the percentage of
total fuel provided by the hazardous
waste to the boiler or industrial
furnace), and the combustion conditions
under which the waste is burned The
risk posed by the emissions depends on
the quantity and toxidty of the
compounds emitted and on the •««M«n*
levels to which persons an exposed.

basis for these standards is discussed

A. DRE Standard
As proposed, the Agency is
promulgating a 99.9098% ORE
standard ll for those acutely hazardous
wastes listed because they contain
dioxin " (and waste mixed with those-
wastes), and a 98.99 percent ORE
performance standard for all other
waste*. This standard is protective, it
can be readily achieved by boilers and
industrial furnaces, and it will ensure
that the Agency's controls an

industrial furnaces, and incmeralots)
that pose similar risks.

actually occurring. It however, during
the permit process, it appears that a
high-risk scenario may exist permit
officials may use the omnibus permit
authority1* of section 3005(c)(3) of the
Resource Conservation and Recovery
Act (RCRA) codified at f 270.32(b)(2) to
develop permit requirements, as
necessary, to protect human health and
the environment (e.g* by requiring a
99.9999 percent ORE. by limiting the feed
rate of particular toxic compounds, or
by setting a mass emissions rate).
1. Selection of POHCs for ORE Testing
In the April 27,1990 proposed rule to
amend the incinerator standards (55 FR
17890), EPA outlined die considerations
to be made by applicants and permitting
officials in selecting POHCs for ORE
trial burns. Given that the ORE
implementation procedures for boilers
and industrial furnaces (BIFs) are
identical to those for incinerators, the
discussions in the incinerator proposed
rule are pertinent to this rule.
A major factor in selecting a POHC
for DRE testing is its incinerability
relative to other toxic organic
compounds. A number of indices can be
used to predict incinerability including
heat of combustion, autoignition
temperature, thermal stability under
excess oxygen conditions, and thermal
stability under low oxygen
(substoichiometric) conditions. An
incinerability ranking based on thermal
stability at low oxygen concentrations
(TSLoOj) shows promise and is
currently seeing widespread use in
incinerator permits. A number of
commenters responded to EPA's request
for comment on the use of the TSLoCs
index for POHC selection. In general.
they raised no problems with use of the
index. Their main concern appeared to
be that EPA choose one index and apply
it consistently.
The Agency, however, is not requiring
the use of a particular index. Due to the
various "failure modes" different
organic compounds are susceptible to
during the destruction process in a
combustion device, and the evolving
state of knowledge in this area, the
Agency feels that the POHC selection
process is technically complex and that
it should involve a number of

considerations, rather than simply one
incinerability ranking. Thus. EPA
instead recommends that permit writers
and applicants consider these indices
and other relevant factors and use their
judgment and applicable guidance on a
case-by-case basis to select POHCs for
the trial bum.
2. Use of POHC Surrogates
A number of laboratory-scale, pilot-
scale, and field-scale tests have been
conducted to investigate the use of
nontoxic tracer surrogates (e.g, sulfur
hexafhioride (SF«)) rather than POHCs
selected from appendix VIE of part 261.
Sulfur hexafluoride, in particular, shows
promise as a conservative tracer
surrogate for compounds which are
susceptible to the thermal failure mode
(i.e.. it is difficult to destroy unless
sufficiently high temperatures are
reached). It is readily available
commercially, and is inexpensive and
nontoxic. POHCs that are listed on
appendix VOL especially in situations
where spiking is required to increase
concentrations in a waste for ORE
testing, are often difficult to obtain, are
expensive, and are a health hazard to
operators. Sampling and analysis
techniques for SF« are well documented
because of its long use as a tracer gas
for monitoring ambient air and are more
straightforward (simpler) and less
expensive than sampling techniques for
appendix VOL part 261, compounds (e.g.,
VOSTandMMS).
Numerous commenters responded to
EPA's request for information on an
approach for simplifying and
standardizing DRE testing. Commenters
supported standardization of DRE
testing provided the approach is
equitable for all boilers, industrial
furnaces, and incinerators. Comments
were received in support of all three
approaches proposed by EPA ("POHC
soup," surrogates, and specific waste
analysis). Commenters generally
supported use of surrogates in lieu of
extensive waste analysis for design of
DRE tests. Other commenters suggested
using a limited number of major waste
constituents as POHCs. such as carbon
tetrachloride. perchloroethylene.
trichloroethylene. and
monochlorobenzene. until it can be
shown that a universal surrogate, such
as sulfur hexafluoride (SF*), is
comparable in demonstrating DRE
performance. Sulfur hexafluoride was
recommended by some commenters as a
good surrogate choice based on the high
accuracy of results with the compound
and ease of use.
However, since the April 27 proposed
rule, data have become available
showing cases where other organic
compounds were more difficult to
destroy than SF* under conditions of
low oxygen. This is consistent with
theory, since SF* can be destroyed under
conditions of high temperature and low
oxygen relatively easily compared to
compounds which need oxygen to
decompose. Thus, although SF* appears
to show promise as a surrogate for
testing the thermal failure mode because
of its stability at high temperatures, it
does not appear to be adequate as a
"universal" surrogate, since it does not
test for low oxygen or "mixing" failure.
Nevertheless, today's rule explicitly
allows the use of surrogate, nontoxic
compounds for selection as POHCs for
DRE testing. As for any other type of
POHC, the use of such compounds must
be approved on a case-by-case basis by
permit officials based on technical
support provided by the applicant. The
applicant's trial burn plan must
adequately document the correlation
between the DRE of the surrogate
compound and the DREs of the
appendix Vffl compounds anticipated to
be burned at the facility under the
facility's permit.
3. Waiver of DRE Trial Bum for Boilers
Operating Under the Special Operating
Requirements
In 1987, the Agency proposed to waive
the trial burn requirement to
demonstrate DREs for boilers that
operate under special operating
requirements (SOR). The SOR required
that in addition to meeting the proposed
100 ppmv CO limit a qualifying boiler
must: (1) Burn at least 50 percent fossil
fuel in the form of oil gas, or coal; (2)
operate at a load of at least 25 percent
of its rated capacity; (3) bum hazardous
waste fuel with an as-fired heating value
of at least 8,000 Btu/lb; and (4) inject the
hazardous waste fuel through an
acceptable atomization firing system.
The SOR were based on the results of
nonsteady-state boiler testing. From
these results, the Agency believed that
boilers operating under the SOR would
maintain a hot stable flame conducive
to maintaining high combustion
efficiency, resulting in maximum
destruction of organic constituents in
the hazardous waste fuel. The Agency
believed that these boilers would
achieve at least 09.99 percent DRE, and
therefore, a trial burn to demonstrate
DRE would not be necessary.
The Agency continues to believe that
boilers operating under die SOR will
achieve 99.99 percent DRE. However.
based on comments received on the
proposed SOR and on further
examination of the previous steady-

state and nonsteady-state boiler test
results, the Agency has made the
following modifications to the SOR:
(1) Limit eligibility for the waiver to
nonstoker, watertube boilers;
(2) Revise the requirement that the
boiler fire 50 percent fossil fuel or fuels
derived from fossil fuel to include tail
oil, to allow permit officials to approve
on a case-by-case basis other
nonhazardous fuels with combustion
characteristics comparable to fossil fuel,
and to requirs for all such primary fuels
(i.e., fossil fuels, tall oil, and other fuels
approved on a case-by-case basis) a
minimum heating value of 8,000 Btu/lb;
(3) Clarify that the hazardous waste
fuel fired must have an as-fired heating
value of 8,000 Btu/lb and require that
each fuel fired in the burner where
hazardous waste is fired must have an
as-fired heating value of 8.000 Btu/lb;
(4) Increase the minimum load
requirement from 25% to 40%; and
(5) Eliminate the lower viscosity
requirements for the hazardous waste
and decrease the upper viscosity limits
for the hazardous waste to 300 seconds,
Saybolt Universal (SSU), measured at
the as-fired temperature of the fuel.
As proposed in 1987, boilers with a
trial burn waiver under the SOR must
meet the Tier I CO limit of 100 ppmv »•
and must comply with all other
requirements of the final rule (e.g.,
metals standards, PM limit).
The revised SOR are presented below,
along with the basis for the revisions.
a. The Boiler Must Be a Nonstoker,
Watertube Boiler. Commenters stated
that the nonsteady-state testing of only
three stoker and firetube boilers is
insufficient to determine whether 99.99
percent ORE would always be achieved
under the SOR. Commenten also
maintained that the stoker and firetube
boilers tested were not representative of
all types and sizes.
The Agency agrees that there is
limited data demonstrating that stoker
and firetube boilers can achieve 99.99%
ORE under the SOR. In the Agency's
steady-and nonsteady-state testing, only
three firetube boilers and one stoker
boiler were tested under steady-state
conditions, and one stoker boiler wai
tested under nonsteady-state conditions.
The remainder of the boilers tested were
watertube boilers.
The results from one of the firetube
boiler tests generally support the ability
of firetube boilers to achieve 99.99
" Boiler* complying with the Tin U PIC control*
where CO level* exceed 100 ppmv ut not eligible
for the automatic waiver of the ORE thai bum. This
it beceuie the ORE test data uaed to support the
waiver wai obtained for bollen operating at CO
level* below 100 ppmv.
percent ORE, but this boiler was
specially designed to combust
hazardous waste. The Agency is
concerned whether more conventionally
designed firetube boilers could easily
achieve this level of ORE. DREs could
not be calculated at one of the other
firetube boiler tests due to inadequate
waste feed levels, and sampling and
analytical problems occurred at the
third firetube boiler test The stoker
boiler tested under steady-state
conditions did not demonstrate 99.99
percent ORE. In addition to the limited
data for these boiler types, a greater
potential exists for poor distribution of
combustion gases and localized cold
spots in firetube and stoker boilers that
can result in poor combustion
conditions. This is because these boilers
generally burn fuels with a large and
variable particle size on a bed, thus,
making even distribution of combustion
air difficult Therefore, the final rule
precludes stoker or firetube boilers from
the automatic waiver of a ORE trial
burn.
b. A Minimum of 50 Percent of the
Fuel fired to the Boiler Must Be High
Quality "Primary" Fuel Consisting of
Fossil Fuels or Fuels Derived From
Fossil Fuels, Tall Oil, or, if Approved on
a Case-By-Case Basis, Other
Nonhazardous Fuel Comparable to
Fossil Fuel, and All Such Primary Fuels
Must Have a Minimum As-Fired
Heating Value of 8,000 Btu/lb. Thirteen
commentera found the 50 percent fossil
fuel requirement to be overly restrictive.
In particular, one commenter proposed
that the requirement be rephrased to
allow the burning of no more than 50
percent hazardous waste in mixtures
such that nonhazardous waste fuel
supplements can be fired. Another
commenter suggested eliminating the
fossil fuel requirement for wastes that
have heating values comparable to fossil
fuels. Eleven commentera supported the
burning of high quality non-fossil fuels,
such as tall oil (i.e., fuel derived from
vegetable and rosin fatty acids) and the
by-products derived from the fractional
distillation of tall oil. Many of these
commenters said they have burned
these materials and claimed they have
heating values and combustion
characteristics similar to fossil fuels.
Three commentera requested that the
burning of wood wastes as a primary
fuel be allowed. One of these
commentera presented the results from
six trial burns for wood waste boilers
which demonstrated that combustion
zone temperatures in these types of
boilers are consistent and that a hot
stable flame conducive to the
destruction of organic constituents in
the waste is present under these
conditions.
Based on the comments and
information presented regarding the use ,
of tall oil (i.e., tall oil burns like
commercial fuel oil), the Agency is
revising the 50% primary fuel
requirement to include tall oil. Also, the
Agency believes that the combustion of
other nonhazardous fuels that have
heating values of at least 8,000 Btu/lb
(representing the lower heating value
range of most sub-bituminous coals),
and combustion characteristics similar
to fossil fuels, will ensure a hot stable
flame conducive to the destruction of
organic constituents in the waste. An
owner/operator who is planning t6 burn
such a fuel supplement must present
information on the supplement's
combustion characteristics for the
Director's review. Concerning wood
wastes, the Agency continues to believe
that these wastes may not provide the
hot stable combustion zone conditions
needed to achieve 99.99 percent ORE.
Due to the higher flue gas moisture,
excess air. CO levels, and lower furnace
temperatures accociated with wood *
firing, the potential for less than 99.99
percent ORE exists. Therefore, boilers
that fire wood wastes must demonstrate
ORE capabilities through a trial burn.
The 50 percent minimum primary fuel
requirement on a total heat or volume
input basis, whichever results in the
greater volume of primary fuel, also is
needed to ensure appropriate
combustion zone conditions. This limit
was based on the maximum levels of
hazardous waste burned in the boilers
tested by EPA under nonsteady-state
conditions.
Finally, the Agency recognized that
the term "fossil fuel" can include peat or
other fuels with heating values below
8,000 Btu/lb. Because the test data used
to support the waiver were from boilers
fired with primary fuels with heating
values higher than 8,000 Btu/lb, the final
rule applies the minimum 8,000 Btu/lb
as-fired heating value limit to all fuels.
including fossil fuels, used to meet the
minimum 50% primary fuel requirement.
c. Boiler Load Must Beat Least 40
Percent Several commenters addressed
the proposed minimum load level of 25
percent Only one commenter
considered it to be too low. This
commenter advocated an 80 percent
load requirement unless high efficiency
combustion can be demonstrated at the
trial bum. One commenter considered
the 25 percent requirement to be
arbitrary, but within current practice.
Another commenter recommended that
the level be more flexible for multiple
burner boilers. One commenter
-------
Federal Register / Vol. 58. No. 35 / Thursday. February 21. 1991 / Rules and Regulations 7149
recommended that the requirement to
maintain a boiler load of 25 percent be
eliminated if the Btu value of the wastes
burned is equivalent to that of coal
thereby providing the heat input
necessary to sustain normal combustion
operations.
Boiler testing conducted at a load as
low as 28 percent has demonstrated that
certain boilers can achieve 99.99 percent
DRE when operated at low loads.
However, due to concerns related to
flame stability, combustion control, and
heat transfer effects associated with
load turndown on some boilers, the
Agency has raised the boiler load limit
from 25 percent to 40 percent of design
load. Operation of some boilers at loads
of less than 40 percent can result in
significantly higher excess air levels and
localized decreases in flame
temperatures, in addition, most of the
boilers tested to develop the operating
requirements operated at loads above
40%. Therefore, limiting the boiler to 40%
is more consistent with the available
test data. If an owner/operator expects
to operate a unit at a lower load while
firing hazardous waste, a thai bum to
demonstrate 99.99 percent DRE is
required.
d. The Heating Value of the
Hazardous Waste Fuel Must Be at Least
3.000 Btu/lb. As-Fired, and Each Fuel
Fired in a Burner Where Hazardous
Waste Is Fired Must Have a Heating
Value of at Least 8.000 Btu/lb. As-Fired.
Eleven commenten expressed concern
that the "as-fired" requirement proposed
in 1987 will require the blending of
wastes that have heating values of less
•nan 8,000 Btu/lb with other wastes
and/or tne primary fuel before
atomization. Four commenters
documented a number of problems with
blending low Btu wastes, including
immisciuility and other mixing
problems, increased quantity of
materials requiring handling, difficulty
of controlling feed during unit upsets.
and impracticality for coal-fired
systems. Five commenters requested
that the heating value be determined on
a total-burner basis, as a composite of
primary fuel and waste. Three
additional commenters recommended
that the minimum heating value of
wastes be lowered to 5.000 Btu/lb.
The Agency agrees that waste fuel
blending can present problems in some
instances. However, the Agency is
concerned that allowing low Btu wastes
to be fired separately from the fuel and
then atomized in the flame region of the
burner might make it difficult to ensure
good atomization. proper feed system
operation, and. consequently, adequate
combustion of the hazardous waste.
Therefore, the 8.000 Btu/lb requirement,
which represents the lower range of
heating values of fossil fuels, applies to
the as-fired heating value of the
hazardous waste and to the as-fired
heating value of any other fuel fired in
the same burner with the hazardous
waste.17
If hazardous waste with a heating
value below 8.000 Btu/lb " is mixed with
the "primary" fuel to meet the as-fired
minimum heating value for hazardous
waste of 8.000 Btu/lb, that quantity of
primary fuel may not be counted toward
the 50% primary fuel requirement. This
is because the purpose of requiring 50%
of the fuel to be "primary" fuel is to
ensure a hot stable flame to combust
the hazardous waste. If a portion of the
primary fuel is blended with the
hazardous waste to increase the heating
value of the hazardous waste as-fired.
then that portion of the primary fuel is
not providing the hot. stable flame.
The following example shows how
this requirement will work. Suppose a
boiler is fired with 70% primary fuel arid
30% hazardous waste, and that half of
the primary fuel is blended with the
hazardous waste to achieve an as-fired
heating value of 8.000 Btu/lb. This boiler
would not be eligible for the automatic
waiver of the DRE trial bum because it
is fired with only 35% primary fuel (half
of the 70%) that is not blended with the
hazardous waste to meet the minimum
as-fired heating value limit of 8,000 Btu/
Ib.
e. The Hazardous Waste Must Be
Fired with an Atomization System.
Seven commenten argued that lower
viscosity limits are unnecessary. Three
commenters stated that it is common to
atomize wastes well below 150-200 SSU,
and that No. 2 oil has a viscosity of 32.8-
37.9 SSU at 100 'F. One commenter
indicated that the upper viscosity limits
appear high for the atomization systems
specified. One commenter disagreed and
said that the high limits are in the
correct range. Six commenten
expressed concern that the particle size
limits are overly restrictive. One

commenters stated that diverse waste
streams can be handled to achieve good
destruction without particle size limits.
Another commenter disagreed with EPA
by stating that they are not familiar with
nozzles designed for particle sizes as
small as 200 mesh. Three commenten
said the waste viscosity should be left to
the discretion of the owner/opera tor
since it is industry practice to operate at
viscosities which provide optimum
atomization.
Based on the commenters' arguments.
the Agency has eliminated the lower
viscosity requirements and reduced the
upper limit to 300 SSU (Seconds, Saybolt
Universal) measured at the as-fired
temperature of the hazardous waste. We
eliminated the lower level because, after
consideration of comments and re-
evaluation, we believe that the concern
stated at proposal—formation of a fog at
low viscosity levels which could result
in poor combustion conditions—is not
likely to occur. At proposal, the Agency
established upper viscosity limits
ranging from 300 to 5.000 SSU. *
depending on the type of atomization
system. Commenters noted that, as a
practical matter, wastes with ai-fired
viscosities greater than 300 are not fired
in an atomization system. These
modifications will give facilities the
flexibility to preheat wastes before
atomization and are consistent with
general industry practice for good
atomization.
Regarding particle size limits the final
rule establishes the proposed limits.
When high pressure air or steam
atomizers, low pressure atomizers, or
mechanical atomizers, 70% of the waste
must pass a 200 mesh (74 micron)
screen. When a rotary cup atomizer is
used. 70% of the waste must pass a 100
mesh (150 micron) screen. These mesh
sizes are consistent with the design
droplet size of the atomizers.
Owners/operators of boilers who
propose to fire hazardous waste outside
these viscosity and particle size limits
must conduct a DRE trial burn.
B. PIC Controls
The burning of hazardous waste, like
virtually any combustion process,
results in emissions of incompletely
burned organic compounds, or products
of incomplete combustion (PICs). PICs
can be unbumed organic compounds
that were present in the waste, thermal
decomposition products resulting from
organic constituents in the waste, or
compounds synthesized during or
immediately after combustion. If a
device is operated under poor
combustion conditions, substantial
emissions of PICs can result (even if
-------
7150 Federal Register / Vol. 56. No. 35 / Thursday. February 21. 1991 / Rules and Regulations
99.99% ORE is demonstrated for POHCs;
this just means that the POHC is not
being emitted in its original form).
However, it should be noted that
estimates of risk to public health
resulting from PICs, based on available
emissions data, indicate that PIC
emissions do not pose significant risks
when BIFs and incinerators are operated
under good combustion conditions.
Nonetheless, the Agency is concerned
about the potential health risk from PICs
because the available information has
serious limitations. It is very difficult to
identify and quantify emissions of
thousands of different compounds, some
of which are present in minute
quantities. Although elaborate and
expensive sampling and analytical
techniques have been developed that
can identify many PICs, many others
cannot be identified and quantified with
current techniques. Further, health
effects information adequate to conduct
a health risk assessment considering
exposure via direct inhalation is not
currently available on many organic
compounds that may be emitted from
combustion systems. Finally, the
available public health and
environmental risk assessment tools are
incomplete. Data ere currently available
to conduct indirect exposure analyses
(e.g., exposure via the food chain,
drinking water, dermal exposure) on
only a few orsanic compounds, and it
will be some time before the Agency
will be able to quantify impacts on
ecological resources on a site-specific
basis for purposes of establishing
emissions standards.
Given the limited information about
the hazards that PIC emissions may
pose. EPA believes it is prudent to
require that boilers and industrial
furnaces operate at a high combustion
efficiency to minimize PIC emissions.
EPA is promulgating today a two-
tiered approach to control PICs as
discussed in the October 29.1989.
supplemental notice (54 FR 43721-28).
Under Tier I. CO is limited to 100 ppmv.
Under Tier II. the Agency is providing
an alternative standard. The facility
need not meet the 100 ppmv CO limit
provided the facility can demonstrate
that the hydrocarbon (HC)
concentration in the stack gas does not
exceed a good operating practice-based
limit of 20 ppmv. The alternative CO
limit under Tier II must be established
during the test burn based on the
average over all runs of the highest
hourly rolling average for each run.
1. Use of a CO Limit to Control PICs.
Generally accepted combustion
theory hold* that low CO flue gas levels
combined with low CO flue gas levels
combined with low excess oxygen levels
indicate a boiler, industrial furnace, or
incinerator is operating at high
combustion efficiency. Operating under
high combustion efficiency helps to
ensure minimum emissions of unturned
(or incompletely burned) organics. In the
first stage of the combustion of
hazardous waste fuel, the POHCs
thermally decompose in the flame to
form other, usually smaller, compounds
termed products if incomplete
combustion. In this first stage of
combustion, these PICs also decompose
to form CO.
The second stage of combustion
involves the oxidation of CO to COt
(carbon dioxide). The CO to CCs step is
the slowest (rate-controlling) step in the
combustion process because CO is
considered to be more thermally stable
(difficult to oxidize) than other
intermediate products of the combustion
of hazardous waste constituents.
Because fuel is being fired continuously,
these combustion stages occur
simultaneously.
Thus, in the waste combustion
process, the "destruction" of POHCs is
independent of flue gas CO levels. CO
flue gas levels cannot be correlated with
DREs for POHCs, and may also not
correlate well with PIC destruction.
Although some emissions data indicate
a weak correlation between CO and
PICs, the data generally indicate that
there is a relationship between the two
parameters: When CO is low. PIC
emissions are relatively low. The
converse may not hold: when CO is
high, PICs may or may not be high.
Low CO is an indicator of the status
of the CO to COj conversion process.
the last rate-limiting oxidation process.
Because oxidation of CO to COt occurs
after the destruction of a POHC and its
(other) intermediates (PICs), the absence
of CO is a useful indication of POHC
and PIC destruction. The presence of
high levels of CO in the flue gas is a
useful indication of inefficient
combustion, and at some level of
elevated CO flue gas concentration, is
an indication of the failure of the PIC
and POHC destruction process.
EPA believes it is necessary to limit
CO levels to levels that are indicative of
high combustion efficiency because the
precise CO level that indicates
significant failure of the PIC and POHC
destruction process is not known. In
fact, this critical CO level may depend
on site-specific and event-specific
factors (e.g., fuel type, fuel mix, air-to-
fuel ratios, and the rate and extent of
changes in these and other factors that
affect combustion efficiency). EPA
believes that limiting CO levels is also
reasonable because: (1) It is a widely
practiced approach for monitoring
combustion efficiency—some boilers
and industrial furnaces are already
equipped with CO monitors, and many
are equipped with flue gas oxygen
monitors; (2) the monitors may pay for
themselves through fuel savings
resulting from operation of the boiler or
industrial furnace closer to maximum
combustion efficiency; and (3) well-
designed and well-operated boilers and
industrial furnaces can readily be
operated in conformance with either the
100 ppmv CO limit under Tier I. or the 20
ppmv HC limit under Tier II.
2. Tier I PIC Controls: 100 ppmv CO
Limit
a. Basis for the 100ppmv CO Limit.
The May 6,1987 proposed rule would
have applied the same CO emission
limits to all boilers and industrial
furnaces: a lower limit of 100 ppmv over
an hourly rolling average and a 500.
ppmv limit over a 10-minute roiling
average. The hazardous waste feed
would be shut off automatically if either
limit was exceeded. However, the
hazardous waste would be cutoff
immediately once the 500 ppmv limit
was exceeded while the waste feed
would be cutoff within 10 minutes if the
100 ppmv limit was exceeded. Further if
the hazardous waste feed was cutoff
more than 10 times in a month, the
proposed rule would have prohibited
further hazardous waste burning
pending review and approval by
enforcement officials. The lower limit of
100 ppmv was selected as representative
of steady-state high efficiency
combustion conditions resulting in PIC
emissions that would not pose a
significant risk. The higher limit of 500
ppmv was proposed to limit the
frequency of emission spikes that
inevitably accompany routine
operational "upsets." such as load
changes and start-ups of waste firing.
While two commenters stated that the
proposed 100 ppmv CO limit is arbitrary,
six commenters supported the Tier I CO
limit of 100 ppmv. One commenter
supported both the 100 ppmv CO limit
over an hourly rolling average, and the
500 ppmv CO limit over a 10-minute
rolling average. Three additional
commenters also expressed support for
the 500 ppmv CO limit over a 10-minute
rolling average. Three other commenters
supported a 500 ppmv CO limit over an
hourly rolling average, and stated that a
maximum 1,000 ppmv CO limit can be
included in addition to a 10-minute
average.
Many commenters opposed the CO
trigger limits and associated limits on
the number of waste feed cutoffs
-------
Federal Register / Vol. 56, No. 35 / Thursday, February 21. 1991 / Rules and Regulations 7151
proposed in May 1987. Primarily.
commenters objected to one set of CO
emission limits as applicable to all
boilers and industrial furnaces. Further.
they argued that PIC emissions will not
be significant if. when the waste feed is
cutoff, the combustion chamber
temperatures are maintained while the
waste remains in the chamber. Six
commenters argued that the trigger
limits will result in increased NO,
emissions. One commenter stated that
NO, and CO cannot be lowered
simultaneously, and added that many
low NO, boilers may not be able to meet
these CO limits. As an alternative, one
commenter stated that a higher Tier I
CO limit should be allowed for less
toxic emissions; however, this
commenter did not provide an
alternative approach for identifying the
toxicity of emissions. One commenter
suggested that EPA retain two
alternatives to the CO standard:
establishing an alternative standard
based on nonmethane. ethane
hydrocarbon (NMEHC) emissions, and a
case-by-case risk assessment approach.
As a result of these and other
comments and further evaluation. EPA
is promulgating the Tier 1 limits based
on a maximum hourly rolling average
CO limit of 100 ppmv. corrected to 7
percent flue gas oxygen content. If this
limit is exceeded, the hazardous waste
feed must be automatically and
immediately cutoff. The final rule does
not restrict the number of waste feed
cutoffs because: (1) Combustion
chamber temperatures must be
maintained after a cutoff; and (2) the
number of cutoffs will be minimized by
allowing CO concentrations to be
averaged over a 60-minute period (i.e..
the hourly rolling average) and by the
recommended use of pre-alanns to
provide time to remedy the problem or
to allow a staged waste cutoff before
reaching the CO limit. Nonetheless, the
Agency retains the authority to limit the
frequency of cutoffs as the facts
warrant. See 5 266.102(e)(7)(ii). The final
rule does not include the proposed 500
ppmv rolling average over a 10-minute
limit on CO because we do not believe it
is needed given that the final rule
requires immediate waste feed cutoff
when the 100 ppmv hourly rolling
average limit is exceeded. In addition,
several commenters argued that the 500
ppmv limit was arbitrary.
In addition. EPA it promulgating
alternative (Tier II) standards (discussed
below), as discussed in the October 1989
supplemental notice, for control of PIC
emissions from boilers and industrial
furnaces. The Agency believes that the
alternative controls will allow facilities
flexibility in meeting both the PIC
controls and NO, emissions standards
(imposed under different regulatory
authorities) simultaneously. The Agency
believes that the alternative, Tier II
standards for control of PIC emissions
are needed to address issues and
concerns raised by commenters on the
proposed rule.
The 100 ppmv CO limit promulgated
today for Tier I is indicative of steady-
state (i.e.. normal), efficient combustion
conditions. The time-weighted average
for the CO limit is provided to
accommodate the CO spikes that
inevitably occur during routine "upsets,"
such as when hazardous waste fuel
firing starts, when there is a load change
on an industrial boiler, or when the
composition of fuels varies. Given that
CO is a sensitive indicator of overall
combustion conditions, and that it may
be a conservative indicator of POHC
and PIC destruction. EPA is
implementing CO control limits based
on time-weighted averages of
exceedances rather than implementing
fixed CO limits. Fixed limits that do not
acknowledge inevitable CO spikes and
that do not give owners and operators
time to adjust combustion conditions
actually could result in greater
emissions of PICs because each time
hazardous waste firing is interrupted,
CO concentrations increase, and
emissions of incompletely burned
organics may also increase. (Note,
however, that there is a requirement to
maintain combustion chamber
temperature after a waste feed cutoff
while waste remains in the chamber that
is intended to minimize HC emissions
after a cutoff.) Thus, any controls on CO
must balance the effects of organic
emissions that may result from overly
stringent CO limits that require frequent
waste feed interruptions with the effects
of emissions resulting from less stringent
controls that acknowledge inevitable
CO spikes.
The Agency has considered whether
the 100 ppmv CO limit is. in fact, too
stringent given that we acknowledge the
limit was chosen from within the range
of reasonable values that may be
considered indicative of good
combustion conditions—50 to 250 ppmv.
We attempted to obtain CO/time
profiles from a number of well-operated
devices to determine the percentage of
time the facilities operated within
particular CO ranges.1* We thought to
use this data to predict the frequency of
waste feed cutoffs that would be
required at various CO limits.
Unfortunately, the analyses could not be
conducted because the facilities we
evaluated were operating under specific
CO limits and their CO levels never
exceeded those limits when burning
hazardous waste. We found that the
facilities learned to comply with the CO
limits they had to meet.
Moreover, we believe that the 100
ppmv CO limit is reasonable for a
number of reasons. Not only is it within
the range of CO levels that are
indicative of good combustion
conditions, but the Agency believes that
it is not too low because: (1) It is higher
than the technology-based 50 ppmv CO
level EPA requires for boilers burning
waste PCBs (see 40 CFR part 761); (2) it
is higher than the CO limits included in
many hazardous waste incinerator
permits; 20 (3) the Agency explicitly
encourages the use of pre-alanns to
minimize the frequency of automatic
waste feed cutoffs:" and (4) the.limit is
implemented on an hourly rolling
average basis which allows and
minimizes the effects of short-term CO
spikes.
We also note that the Agency may
soon promulgate regulations for
municipal waste combustors (MWCs)
that among other controls, may limit CO
concentrations to 50,100. or 150 ppmv
(as proposed), depending on the type of
MWC over a four hour rolling average
and dry-corrected to 7% oxygen. The
MWC limits are technology-based—they
represent levels readily achievable by
well-designed and well-operated units.
EPA does not believe that the MWC
limits present a conflict with the 100
ppmv (with provisions for an alternative
higher limit if HC concentrations are
less than 20 ppmv) limit for BIFa under
today's rule. The Agency is confident

ppmv CO limit will ensure protection of
human health and the environment.
As stated above, the CO limits are
based on a flue gas oxygen content of 7
percent One commenter indicated that
EPA's reasoning for using the CO
correction of 7 percent oxygen is not
clear. The commenter believes the 7
percent correction factor is unfair for
thermal units which, under normal
conditions, need to operate at oxygen
levels greater than 7 percent, yet operate
with low levels of CO and HCa. EPA
believes that correcting CO Ieveh for
flue gas oxygen conlm! is necessary
because without this correction, high CO
flue gas concentrations could be dftnted
by high rates of excess oxygen, in
today's rute. EPA is requiring that CO be
corrected to a fine gas oxygen content of
7 percent because the majority of boilers
and industrial furnaces achieve high
combustion efficiency at optimum floe
gas oxygen levels Tanging from S percent
to 10 percent The optinmm oxygen level
to achieve high combustion efficiency
for « given device will vary depending
on factors such M fuel mix and boiler
load. In general, large combustion
devices (in terms of heat input capacity)
have optimum oxygen requirements on
the low end of the range of oxygen
content while smaller units require
higher oxygen levels. EPA believe* that
a correction level of 7 percent is
reasonable since this oxygen level is in
the middle of the range of typical
operation for ail devices and since the
majority of devices burning hazardous
waste fuels have moderate neat input
capacities (e«, 20-150 MM Btn/hr). In
addition, 7 percent oxygen is the
reference level for the existing
particuiate standard for hazardous
waste iodneraton under 40 CFR
264.343(c).
Moreover, the oxygen level to which
CO values ere corrected is not
significant since the CO levels far all
facilities ere corrected to a common
basic. If the oxygen catrection,
were changed from 7% to aome other
value, then theoretically, die CO limit
would have to be edjueted eooordinglf,
aad the effect on individual iaciHJties
would remain the same.

Compliance with the Tier I CO Limit.
The Agency considered a number of
alternative approaches for evaluating
CO readings during trial burns to
determine compliance with the 100
ppmv limit, including: (1) The time-
weighted average (or the average of the
hourly rolling averages); (2] the average
of the highest hourly rolling averages for
all trial burn runs; or (3) the highest
hourly rolling average. The time-
weighted average alternative provides
the lowest CO level that could
reasonably be used to determine
compliance, and the highest hourly
rolling average alternative provides the
highest CO level that could reasonably
be used. EPA is requiring the use of the
most conservative of these approaches,
the highest hourly rolling average
approach, for interpreting trial burn CO
emissions for compliance with the 100
ppmv Tier I limit (This approach is
conservative because trial burn CO
levels are compared to the maximum
CO allowed under Tier I—100 ppmv.)
EPA believes this conservative
approach is reasonable since
compliance with the Tier I CO limit
allows applicants to avoid the Tier II
requirement of evaluating HC emissions
to provide the additional assurance (or
confirmation) that HC emissions do not
exceed levels representative of good
operating practice.
3. Tier II PIC Controls: Limits on CO and
HC
a. Need for Tier II PIC Controls.
Commenters indicated that several
types of boilers and many cement kilns
will not be able to meet the (Tier I) 100
ppmv CO limit proposed in May 1967
even though HC concentrations will not
be high at elevated CO levels. For
example, boilers that bum residual oil or
coal typically operate with CO emission
levels above the Tier 1100 ppmv CO
limit because of inherent fuel
combustion characteristics, equipment
design constraints, routine transient
combustion-related events, requirements
for multiple fuel flexibility, and
requirements for compliance with NO,
emission standards established under
the Clean Air Act Attempts to reduce
CO emissions from these devices to
meet the Tier I limit could prove
unsuccessful. In addition, there is a
possibility that thermal efficiency could
be adversely affected if these attempts
are successful.
Similarly, industry and trade groups
for the cement industry voiced strong
opposition to the 100 ppmv CO limit for
cement kilns. These commenters
indicated that some cement kilns.
especially modem precalciners,
routinely emit CO above the Tier 1100
ppmv limit In general, commenters
indicated that while the Tier I limit may
be appropriate for combustion devices
in which only fuel (fossil or hazardous
waste) enters the combustion chamber.
it is inappropriate for cement kilns and
other product kilns in which massive
amounts of feedstocks are processed.
These feedstocks can generate large
quantities of CO emissions which are
unrelated to the combustion efficiency
of burning the waste and fuel. Whereas
all the CO from boilers and some
industrial furnaces is combustion-
generated, the bulk of the CO from
product kirns can be the result of
process events unrelated to the
combustion conditions at the burner
where wastes are introduced.19
Therefore, limiting CO emissions from
these combustion devices to the Tier I
100 ppmv level may be difficult and may
not be warranted as a means of
minimizing risk from PICs.
In summary, commenters argued that
these are specific instances and classes
of combustion devices for which the
Tier I CO limit would be difficult or
virtually impossible to meet and thus
this limit is inappropriate since EPA has
not established a direct correlation
between CO emissions, PIC emissions.
and health risks.
In light of these concerns, commenters
suggested that EPA establish CO limits
for specific categories of combustion
devices based on CO levels achieved by
units operating under best operating
practices (BOP). The Agency considered
this approach but determined that
equipment-specific CO trigger limits
would be difficult to establish and
support and would not necessarily
provide adequate protection from PIC
emissions. Nonetheless, EPA believes
that the CO limits should be flexible to
avoid major economic impacts on the
regulated community since no direct
correlation has been established
between exceeding the 100 ppmv CO
limit and increasing health risks from
PIC emissions. EPA believes, however.
that at some elevated CO level PIC
emissions would pose significant risk.
At this time. EPA is unable to identify •
precise CO trigger level since the trigger
level may vary by the type and design of
the combustion device and the fuel mix
used in the device. Consequently, EPA
has established a two-tiered approach to
control PICs. Under Tier I. CO is limited
to 100 ppmv or less, as discussed above.
Under Tier II. CO levels can exceed 100
ppmv provided that the owner or
operator demonstrate that the HC
concentration in the stack gas does not
exceed a good operating practice-based
limit of 20 ppmv (except that the
Director may establish under
5 266.104(f) an alternative HC limit for
furnaces that feed raw material
containing organic matter and. thus.
cannot meet the 20 ppmv limit).
Under Tier II. the CO limit for a
facility is based on the levels achieved
during a successful compliance test. The
Agency originally proposed two
alternative approaches for establishing
HC emission limits under the Tier II
waiver, a health-based approach and a
technology-based approach. These two
alternatives and EPA's rationale for
selecting the technology-based approach
for the final rule are discussed below.
Before moving to those discussions.
however, it may be useful to summarize
the conclusions of an evaluation by
EPA's Science Advisory Board of the
proposed PIC controls.
b. Comments by EPA's Science'
Advisory Board (SAB). We present
below a summary of SAB's
conclusions *• on the scientific support
for EPA's proposed PIC controls and
EPA's response:
• SAB: The Agency has not
documented that PICs from hazardous
waste combustion can cause significant
health risk to human health or the
environment.
—EPA Response: While the Agency
agrees that available data do not
show that PICs are likely to pose a
significant health risk. EPA's
emissions testing to date has been
able to identify and quantify only as
much as 60% of the organic
compounds being emitted during any
test During many of EPA's tests, less
than 5 to 10% of organic emissions
were characterized. The Agency is
concerned that this large fraction of
uncharacterized organic emissions
could be comprised of compounds that
can pose significant health risk.
Therefore, the Agency believes that
PICs have the potential to present a
hazard and should be controlled.
• SAB: It is prudent to control PICs
given the inability to show that they do
not pose a health risk because of
limitations of sampling and analytical
techniques and health and
environmental impact assessment data
and methodologies.

Containing organic matter), reported as_

dry basis.
The Agency considered whether to
establish provision for a case-by-case
waiver of the 23 ppmv KG limit based
either on health-risk assessment or
technical feasibility (i.e.. feasibility of
providing combustion conditions to
minimize fciei-senerated HQ. The final
rule does not provide for a waiver of the
20 ppmv HC Unit as an indicator of
ireod ccrr.bastion conditions and
minuTum fuel-generated PIC emissions.
(The final rule does, however, allow the
Director to establish under the part B
permit proceedings an alternative HC
limit for industrial furnaces (e.g, cement
kilns, lieht-wfiipht aggregate kilns) to
account for hydrocarbons that are
emitted from trace levels of organic
matter in the raw material. Any
alternative HC limit established for a
furnace wul ensure that fuel-generated
hydrocarbons (hazardous waste and
ether fuels) are less than 20 ppmv by
establishing the HC limit based on HC
concentrations when the system is
desicned and operated under good
combustion conditions without burning
hazardous waste.17 See section ILJL5 of
kPart Three of this preamble for more
'discussion of the alternative HC limit lor
industrial furnaces.)
EPA did not provide a waiver of the
HC limit in the final rule because: (1)
The Agency believes, and SAB concurs.
that a site-specific, health risk
assessment approach to establishing HC
limits (e-g., a waiver of the 20 ppmv
Hmit) is not scientifically supportable:
and (2) a technology-based waiver is not
supportable because well-designed and
operated hazardous waste combustion
devices can readily meet a 20 ppmv HC
limit
Several commenters disagreed with
EPA that both CO and HC should be
monitored, stating that it is unnecessary
• o monitor CO if HC is monitored. The
.\a«icy continues to believe that it is

emission levels may respond more
quickly to process upsets than HC
levels, the apparent redundancy in
requiring both CO and HC monitoring is
warranted to ensure protection of
human health.
Another commenter added that HC
monitoring could be supplemented by
frequent testing for common PICs that
respond poorly to HC monitors, such as
carbon tetrachloride. formaldehyde.
perchlorethylene, and chlorobenzene. At
this time, the Agency believes that
continuous HC monitoring combined
with CO monitoring is adequate in most
cases to detect when the facility is
operating under combustion upset
conditions (this is another reason.
however, that monitoring both CO and
HC is reasonable when CO levels
exceed the level normally indicative of
good combustion— 100 ppmv). We note
that as discussed in section fJ.D below
the final rule requires a hot HC
monitoring system (Le., unconditioned
gas sample heated to a minimum of ISO
*C) which ensures m'"irmim loss of
organic compounds. Nonetheless, the
Agency is currently developing sampling
and analytical techniques to
continuously monitor indicator organic
compounds such as more suggested by
the commenter.
e. Basis for Firm! Rule. EPA believes
that the 20 ppmv HC limit in the final
rule for the Tier n PIC controls is
representative of an HC limit that
distinguishes between good and poor
combustion conditions. (When a facility
operates under poor combustion
conditions. PIC emissions can increase
and may result in adverse health effects
to exposed individuals.) This HC limit is
within the range of values reported in
the Agency's data base for hazardous
waste incinerators, boilers, and
industrial furnaces that bum hazardous
waste, and the limit is also protective of
human health based on risk assessments
conducted for 30 incinerators. See 34 FR
43723. Under Tier II. HC must be
monitored continuously, recorded en an
hourly rolling average basis, reported as
ppmv propane, and corrected to 7
percent oxygen on a dry basis. In
addition, CO must be monitored
continuously, corrected to 7 percent
oxygen on a dry basis, recorded on e.r.
uourly rolling average basis, and may
not exceed the limit established during
the test bum (i.e.. the average over all
runs of the highest hourly rolling
average for each run).
4. Special Requirements for Furnaces
The final rule provides several special
requirements for industrial furnaces
stemming from the fact mat: (1) Some
industrial furnace*, notably cemant
kilns, are not able to meet the 20 ppmv
HC limit because trace levels of organic
matter in raw materials can emit
substantial levels of hydrocarbons: and
(2) the PIC controls may not be
protective for furnaces (e-g.. cement
kilns and mineral wool cupolas) that
feed hazardous waste at locations other
than where normal fuels are fired. These
special requirements are discussed
below.
a. Alternative HC Limit EPA
requested comment on whether
alternative HC limits may be
appropriate for certain industrial
furnaces. See 54 FR 43724 {Oct 28.1989)
A number of commenters *• requested
that EPA allow cement loins, light-
weight aggregate kilns, and lime kilns
that cannot meet the 20 ppmv HC limit
because of the hydrocarbons generated
by trace levels of organic materials in
the normal raw materials to establish a
site-specific alternative HC limit that
does not allow HC levels when burning
hazardous waste to be significantly
higher than when burning normal fuels.
processing normal raw materials, and
producing normal products in a system
that is designed and operated to
minimize hydrocarbon concentrations in
stack gas. Nineteen commenters pointed
out that baseline HC emrnion levels
from cement kilns can be attributed to
the naturally-occurring raw materials
that are used in the production of
cement Use of shale as a raw material.
for example, can result in HC emissions
from kerogens in the shale. Use of fly
ash as a source of iron and silica could
result in increased CO emissions from
partial oxidation of free carbon in the fly
ash. Commenters claim that
approximately 6 to 10 cement plants
may not be able to comply with the HC
limit of 20 ppmv even though they
generate minimal HC from sources other
than raw materials (e.g.. hazardous
waste fuels, other fuels, organic
compounds in slurry water). The organic
compounds in normal raw materials
would not ordinarily be hazardous, so
.hat their emissions (e.g., through
volatilization) would not raise the types

Fwknl Rttistar / VoL 56, No. 35 / Thursday, February 21. 1991 / Rules and Regulation*
The Agency believe* that it will be
possible in some situations to develop
an approach on a case-by-case basis to
effectively implement an alternative HC
limit under the principle stated above.
(If the 20 ppmv HC limit were health-
based, the Agency would be more
reluctant to develop an alternative to it.
Given, however, that the limit is a
measure of combustion efficiency, the
Agency believes it reasonable to
develop an alternative means for this
class of furnaces to demonstrate
combustion efficiency.) The Agency
considered a number of approaches to
establish an alternative HC level and
determined in the time available that
none appeared to be workable in all
situations. The Agency is therefore
adopting a more individualized
approach in the present rule that allows
permit writers to establish an
alternative HC limit (i.e.. a HC limit that
exceeds 20 ppmv) in a facility's
operating permit and allows permit
writers to grant an extension of time to
comply with the HC limit during interim
status, based on the following showings:
(1) For cement kilns, the kiln is not
equipped with a by-pass duct that meets
the requirements of f 206.104(0(1); (2)
the applicant demonstrates that the
facility is designed and operated to
minimize hydrocarbon emissions from
fuels and raw materials: (3) the
applicant develops an approach to
effectively monitor over time changes in
the operation of the facility that could
reduce baseline HC levels—for example.
changes in raw materials, fuels, or
operating conditions—which could
result in establishing a new baseline
and corresponding adjustment of the HC
limit: and (4) the applicant demonstrates
that the hydrocarbon emissions are not
likely to pose a significant health risk.
See i 266.104(0(2). We explain these
provisions in more detail below, along
with an explanation of which provisions
apply during interim status and which
are part of permit application and
issuance.
Interim Status Facilities. Today's rule
requires facilities operating in interim
status to comply with CO and. if
required, a 20 ppmv HC limit within 18
months of the rule's date of
promulgation. The rule provides for a
case-by-case extension from these
requirements (as well as the paniculate.
metals, and HC1/CU standards) "if
compliance is not practicable for
reasons beyond the control of the owner
or operator." See i 286.103(c)(7)(ii). The

unable to achieve the 20 ppmv HClimit
because of organics present at baseline
conditions (i.e.. when the facility is
designed and operated to minimize HC
emissions from raw materials and fuels
while producing normal products under
normal operating conditions and when
no hazardous waste is burned) may be
eligible for the extension of time
provided the following conditions are
satisfied:
1. The applicant for the extension of time
must have submitted a complete part B
permit application. The application must
include the following information pertinent to
the question of an alternative HC limit (a)
Documentation that the system is designed
and operated to minimiM HC emissions from
all sources when the baseline level is
established and when hazardous wasta is
burned; (b) documentation of the baseline HC
flua gas concentrations when the facility is
operated to minimize HC emissions and
when feeding normal raw materials and
normal fuels to produce normal products
under normal operating conditions and when
not burning hazardous waste: (c) a test
protocol to confirm the baseline HC (and CO)
level: (d) a trial burn protocol to demonstrate
that when hazardous wasta is burned. HC
(and CO) concentrations do not exceed the
baseline level: and (e) a procedure to show if
and when HC emissions from nonhazardoua
watte sources may decrease (in which case,
the overall HC limit might be adjusted
downward after a new baseline is
established). See i 270.22(b). (The
substantive basis for these requirements is
explained in more detail below.)
2. During interim status, the applicant must
not only conduct emissions testing when
burning hazardous to certify compliance with
all remaining emissions controls—dioxins
and furans. PM. metals, and Hd/Clt—but
also establish and comply with interim limit*
on CO and HC presented in the part B permit
application as levels the applicant has
determined by testing (without burning
hazardous waste) are baseline levels. We
note that the Director may not have time
during the review of the extension request
(and a preliminary review of the part B
application) to confirm the adequacy of the
mtenm CO and HC limits proposed by the
applicant. Moreover, to do so would require
the types 01 oversight of test protocols.
emissions testing, and review of data that
will be applied under the permit process.
Thus, the interim limits are subject to
revision based on (confirmation) testing in
support of the operating permit. Nonetheless.
EPA believes that establishing interim CO
and HC limits and requiring the owner/
operator to comply with them until a permit
is issued (or denied) is reasonable and
provides a measure of protection of human
health and the environment
It should be noted that the Agency does not
believe that it is possible to establish an
alternative HC limit during interim status.
This is because the level of interaction
between an applicant and permit writer over
evaluation of the venous protocols to
establish a HC baseline and determine whan
it should be reduced, plus conducting test
burns to confirm the HC b^f*1"" and that
HC levels do not increase when I
waste is burned, plus conducting a healf
risk assessment for organic emissions \
hazardous wasta is bunted are beyond the*
scope of interim status. Consequently, the
rule is structured so that the alternative HC
limit (if warranted) would be established as
part of the permit and the interim status
certification of compliance deadline can be
extended, if the Director finds this is
warranted, while the permit is being
processed. The Director may also make the
extension of **m* conditionai on the ^"**
estimated to process the permit application or
other factors, and can be conditioned on
operating conditions than ensure the facility
will operate in a manner that protects human
health and the environment Any such
condition would be embodied in an interim
status extension determination that is
enforceable as a requirement of subtitle C
(much aa conditions in a closure plan an
enforceable), and would be documented in an
administrative record for the determination.

and data documenting compliance with

§ 270.22(b). First the applicant must

including raw materials and fuels.
Examples of situations where the
system is not designed and operated to
minimize HC (and CO) levels during
baseline testing are when: (1) Coal is
mixed with raw material which is fed
into a cement kiln preheater such that
the coal can contribute to HC emissions:
(2) cement kiln slurry water contains
enough organic compounds to
significantly contribute to HC emissions:
(3) weste fuels such as tires are burned
in a manner that could contribute to HC
emissions: (4) the furnace is not
operated and designed to minimize
emissions of hydrocabons emitted from •
raw material (in general the more
quickly the raw material is exposed to
elevated temperatures, the lower the
hydrocarbon emissions): and (S) normal
fuels are not burned under good
combustion conditions.
Second, the applicant must pr

CO and HC levels. These proposed
baseline levels also serve as interns
values tinder which the facility must
operate under a conditional time
extension for certification of compliance
with the HC standard until permit
issuance (or denial). The proposed
baseline levels must be supported by
emissions testing under baseline
conditions (ue- when die facility ia
designed and operated to minimize HC
emissions from raw materials and fuels
while producing normal products under
normal operating ftmAMmm and whea
no hazardous waste is burned). Baseline
levels must be determined from test
data as die average over all vatid runs
of the high»«t hourly rolling average
value for each run. This is the same
approach specified by the rule to
determine Limits on other opera ting
parameters (eg- maximum feed rate
limits, maximum temperatures, etc). EPA
believes that this approach is workable
for cement kilns *° given that
commeniers have asserted that •when
hazardous waste is burned,
hydrocarbon levels do not increase and
often deccease. As disousnari in section
1I.E of Part Three of the preamble. HC
levels from a cement kiln-with HC levels
of 66 to 70 ppmv when burning coal
decreased to 38 to 43 ppmv when
burning hazardous waste fuel If the
facility cannot install continuous
monitors for HC (and CO and oxygen) in
time to conduct these baseline tests
prior to submittal of the permit
application (which must be sufficiently
prior to 13 months after promulgation of
the rule to give the Director time to
consider whether to grant the time
extension), the facility may use portable
monitors. We note that the HC
monitoring system must be a hot
unconditioned system. In addition, we
note that different baseline values may
be necessary for different modes of
operation if the baseline HC (or CO)
level changes significantly under those
modes of operation. Examples are when
the raw material mix is changed to make
a different cement product or when
different fuels are burned.
Third, the applicant must develop
emissions testing protocols to: (1)
Confirm the baseline HC and CO levels
proposed in the permit application (and
under which the facility must operate in
interim status upon receipt of an
extension of time to comply with the HC
limit and until an operating permit is

demonstrate that when hazardous
waste is burned, HC and CO levels do
not exceed baseline levels (and
emissions of other pollutants do not
exceed allowable levels). If a baseline
HC or CO level is to be established for
more than one mode of operation, a
baseline confirmation test (comprised of
at least three valid runs) must be run for
each mode.
Fourth, the applicant must develop an
approach to effectively monitor over
time changes in the operation of the
facility that could sjgaificaatly reduce
baseline HC or CO levels. If baseline
levels are significantly reduced, then the
alternative HC and CO limits dial apply
when burning hazardous waste must
also be reduced. Such changes could
include: (1) Changes in the
concentration of organic matter in raw
materials; (2) changes ia the
concentration of organic matter in the
raw material mix due to changes in the
mixture of raw materials needed to
produce different types of product; (3)
changes in fuels; and (4) changes ia die
concentration of organic compounds in
slurry water used for a wet cement kiln.
The approach must be workable and
enforceable.
EPA is requiring this condition in
Order tO aVOid g«*ahli«hinn g high

also lowering die HC limit, potentially
allowing die hazardous waste to be
burned under poor combustion
conditions creating high, but undetected.
HC levels (i.e., hazardous waste could
be burned under poor combustion
conditions and could be emitting high
HC levels even though die HC limit was
not exceeded). (The Agency notes that
the problem of establishing a HC
baseline and for determining when die
baseline might change for this type of
industrial furnace is more difficult than
determining when die raw material
baseline changes in documenting when
co-combustion of hazardous waste with
raw materials in a BeviU device might
affect the composition of residues. See
section Xm of Part Three of die
preamble. This is because, in die case of
die HC baseline, not only must die raw
materials' and fuels' composition be
monitored, but the units design and
operating conditions as well to
determine whether die baseline has
changed. Thus, the rule provides for
more '"fot-nrtinn in establishing Kaolin*
conditions and determining when they
change for assessing alternative HC
limits forcemeat kilns than it does when
making determinations as to whether co-
combustion of hazardous waste can
remove residues from eligibility for
exclusion under the Bevill amendment.)
Finally, EPA is concerned that
hazardous waste burning may affect the
type and concentration of organic
compounds emitted from an industrial
furnace that has elevated HC
concentrations attributable to raw
materials. For example, die chlorine in
the hazardous waste may result in
higher concentrations of chlorinated
organic compounds. Therefore, the rule
requires die owner or operator, as part
of die permitting process, to use state-of-
the-art emissions testing procedures and
risk assessment to demonstrate that
organic emissions are not likely to pose
unacceptable health risk. The owner or
operator must c'viuc* emissions testing
during die trial burn to identify and
quantify the organic compounds listed in
appendix Vm, part 281. that may be
emitted using test procedures specified
by die Director on a caaa-by-case basis.
As noted above, aldaough EPA does not
believe such risk-based approaches to
be adequate as die basis for a national
risk-based PIC standard. w« think the
approach is part of die best means of
assuring that cement kilns combust
hazardous waste fuels properly in those
instances where HC levels ate greater
than 20 ppmv as a result of organics in
normal raw material feed.
Two sampling and analysis
approaches dial the Director may use
are discussed below. One protocol
involves die following steps to identify
and quantify concentrations of organic
compounds in stack emissions:
1. Sample volatile organic compounds using
the VOST train of Method 0030 as prescribed
in SW-MB. Analytical work it conducted
using GC/MS according to Method SOW in
SW-646.
2. Sample semi-volatile organic compounds
using the sampling train preacribed in
Method 0010 in SW-64B. Analytical work it
conducted using GC/MS according to Method
8270 in SW-B46.
3. Sample aldehydes and ketoaes using «n
impinger train with 2-4-di-nitro-pinnyl
hydrazina. (2-4-DNPH) in the impinger
solution as prescribed in Method 0011 in the
Methods Manual, and analysis of impinger
solution by high performance liquid
chramatography (HFiQ «• specified in
"Analysis for Aldehydes and Ketones by
High Performance Liquid Chromstography" in
the Methods Manual.
Another protocol is a screening
approach that has been described in die

To select an appropriate protocc. the
Director will consider the state-of-".a-
art of sampling and analytical
techniques and the expected nature of
organic emissions considering emissions
data or other information.
We note that under this PIC risk
assessment, emission rates must a.--.o be
determined for the 2,3.7.8-chlorinat':d
tetra-octa congeners of chlorinated
dibenzo-p-dioxins and dibenzofura.-;s

The risks from these congeners must be
estimated using the 2.3,7,8-TCDD
toxicity equivalence factor prescribed in
"Procedures for Estimating the Toxicity
Equivalence of Chlorinated Dibenzo-p-
Dioxin and Dibenzofuran Congeners" in
Methods Manual.
The owner or operator must then
conduct dispersion modeling to predict
the maximum annual average ground
level concentration of each such organic
compound. On site ground level
concentrations must be considered if a
person resides on-site: otherwise, only
off-site concentrations may be
considered. Di.-oersion modeling must
be conducted in conformance with
EPA's Cuidelir" on Air Quality Models.
EPA's "Hazarr 'us Waste Combustion
Air Quality Scr -ming Procedure"
provided in Mr'nods Manual, or EPA's
Screening Procedures for Estimatinn Air
Quality Impact of Stationary Sources.
The Methods Manual and the Guideline
on Air Quality Models are incorporated
in today's rule as appendices IX and X.
respectively, to part 266. The Screening
Procedures document is incorporated by
reference in § 260.11.
Stack heights exceeding good
engineering practice (GEP. as defined in
40 CFR Sl.lOO(ii)) may not be used to
predict ground level concentrations. See
section V.B.1.C of Part Three of this
preamble.
If the owner or operator applies for an
alternative hydrocarbon limit for more
than one industrial furnace such that
emissions from the furnaces are from
more than one stack, emissions testing
must be conducted on all such stacks
and dispersion modeling must consider
emissions from all such stacks.
To demonstrate that the
noncarcinogenic organic compounds
listed in appendix IV of the rule do not
pose an unacceptable health risk, the
predicted ground level concentrations
cannot exceed the levels established in
that appendix.
To demonstrate that the carcinogenic
organic compounds listed in appendix V
of the rule do not pose an unacceptable
health risk, the sum of the ratios of the
predicted ground level concentrations to
the levels established in the appendix
cannot exceed 1.0. This is because the
acceptable ambient levels established in
appendix V are based on a 10"* risk
level. To ensure that the summed risk
from all carcinogenic compounds does
not exceed 10~* (i.e.. 1 in 100.000) the
sum of the ratios described above must
be used. (We note that the 2.3.7.8-TCDD
toxicity equivalency factor is to be used
to estimate the risk from 2.3.7,8-
chlorinated CDDs/CDFs, and the risk
from these congeners must be added to
the risk from other PICs to ensure that
the summed risk does not exceed 1 in
100.000.)
To demonstrate that other compounds
for which the Agency does not have
adequate health effects data to establish
an acceptable ambient level are not
likely to pose a health risk, the predicted
ambient level cannot exceed 0.1 fig/m*.
This is the Sth percentile lowest
reference air concentration for the
compounds listed in appendix IV of the
rule.
b. Feeding Waste at Locations other
than the Hot End. If hazardous waste is
fed into an industrial furnace at
locations other than the "hot" end
where the product is normally
discharged and where fuels are
normally fired, the rule requires the
owner/operator to monitor HC
irrespective of whether CO levels do not
exceed the Tier I limit of 100 ppmv and
to comply with special restrictions
during interim status. These provisions
are discussed below.
Mandatory HC Monitoring.M Except
as indicated below, facilities that fire
hazardous waste into an industrial
furnace at locations other than the "hot"
end where the product is normally
discharged and where fuels are
normally fired must comply with tfflVC
limit even if CO levels do not exceed the
Tier I limit of 100 ppmv. See f 266.104(d).
This is because the Agency is concerned
that the hazardous waste could
conceivably be fired at a location in a
manner such that nonmetal compounds
in the waste may be merely evaporated
or thermally cracked to form pyrolysis
by-products rather than completely
combusted. If so. little CO may be
generated by the process and. thus.
monitoring CO alone would r.ot ensure
that HC emissions were minimized.
However, if hazardous waste is
burned (or processed) solely as an
ingredient HC monitoring is not
automatically required because
emissions of nonmetal compounds are
not of concern. This is because the
metals emissions controls will ensure
that metals emissions do not pose a
hazard. (The rule establishes the
restrictions discussed below because we
are concerned that the interim status
controls on organic emissions may not
be protective when hazardous waste is
fed at locations other than the "hot" end
of a furnace.) See discussion in section
VILH of Part Three of this preambj&Jor
when a waste is considered to be
burned solely as an ingredient.**'
Interim Status Restrictions. In
addition to requiring HC monitoring
when hazardous waste is fed into a
furnace at locations other than the "hot"
end where the product is discharged arid
where fuels are normally fired, today's
rule applies other restrictions to
hazardous waste burning during interim
status. See i 266.103(a)(5). The
hazardous waste may not be fed at any
location where combustion gas
temperatures are less than 1800 *F. and
the owner or operator must demonstrate
that adequate oxygen is present to
combust the waste. In addition, for
cement kilns, the hazardous waste must
be fed into the kiln itself. These
requirements are provided to ensure
adequate destruction of the waste given
that the ORE standard (which requires a
demonstration by trial bum that organic
constituents in the waste are destroyed)

is not applicable during interim status.
Like the requirement for mandatory HC
monitoring, however, these restrictions
do not apply if the hazardous waste is
burned (processed] solely as an
ingredient. For further discussion, see
section VII.H of Part Three of this
preamble.
5. Special Considerations for Cement
Kilns
a. Monitoring in the By-Pass Duct of a
Cement Kiln. The final rule provides
that cement kilns with by-pass ducts
may monitor CO and. if required. HC
concentrations in the by-pass duct. Most
precalciner and some preheater kilns
are equipped with by-pass ducts where
a portion (e.g.. 5-30%) of the kiln off-gas
is diverted to a separate air pollution
control system (APCS) and, sometimes,
a separate stack. A portion of the kiln
gases are so diverted to avoid a build-up
of metal salts that can adversely affect
the calcination process. Dust collected
from the by-pass APCS is usually
disposed of while dust collected from
the main APCS is usually recycled back
into the kiln to make the clinker product.
Several comments were received
regarding sampling at cement kilns. Five
commenters suggested that HC (and CO)
measurements should be allowed in the
by-pass duct rather than in the main
stack because: (1) The by-pass gas is
representative of the kiln off-gas; and (2)
this approach would preclude the
problem of nonfuel HC emissions from
the raw material exceeding the 20 ppmv
limit. The raw material would be heated
and partially calcined in the precalciner
or preheater and HC from that process
would be emitted from the main stack.
The by-pass duct draws the kiln off-gas
prior to the precalciner or preheater and,
so. would not be affected by that
process.
Another commenler specifically
supported monitoring CO (and HC. if
required) only in the bypass duct
provided that hazardous waste is fed
only to the kiln and not to the preheater
or precalciner.
The Agency conducted testing »* at a
cement kiln to gather information
relevant to ihe issue of HC monitoring in
the bypass duct for preheater and
precalciner cement kilns. The data
showed that the gases in the bypass
duct are representative of the
combustion of waste in the kiln.
Based on this test data end public
comment, the final rule allows CO and.
where required. HC monitoring in the
bypass duct of a cement kiln provided
that: (1) Hazardous waste is fired only
into the kiln (i.e., not at any location
downstream from the kiln exit relative
to the direction of gas flow); and (2) the
bypass duct diverts a minimum of 10% of
kiln off-gas. See { 266.104(g). The 10%
diversion requirement is based on
engineering judgment that, at this level
of kiln-gas diversion, the bypass gas will
be representative of the kiln off-gas.
Industry representatives indicate " that
the bypass duct capacity of most
facilities actively involved in burning
hazardous waste exceeds the 10% limit.
b. Use of Hazardous Waste as Slurry
Water for Wet Cement Kilns. Some kiln
operators have inquired as to what
regulatory standards apply, if any, if
hazardous wastes are used as slurry
water. The Agency does not regard the
practice as an excluded form of
recycling. The Agency has long been
skeptical of claims that hazardous
wastes are "recycled" when they
substitute for very commonly available
and economically marginal types of raw
materials. In particular, the Agency has
been skeptical that liquid hazardous
wastes serve as a substitute for water.
Cf. 48 FR at 14489 (April 4.1983). In the
case of hazardous waste used as slurry
water, the hazardous constituents in the
waste are ordinarily unnecessary to the
claimed recycling activity and are being
gotten rid of through the slurrying
process. Given the possibility of
hazardous levels of air emission is high,
the practice certainly can be part of the
waste disposal problem. Consequently,
the Agency regards such practice as a
form of waste management subject to
regulation under today's rule.
EPA considered prohibiting the use of
hazardous waste as slurry water for wet
cement kilns because of concern that
toxic organic constituents in the waste
could be volatilized and emitted without
complete combustion. The final rule
does not prohibit using (or mixing)
hazardous waste with slurry water
because we believe that the controls
provided by the rule both during interim
status and under a RCRA operating
permit adequately address the hazard
that the practice may pose.
If hazardous waste is fed into any
industrial furnace during interim status
at a location other than the hot. product
discharge end. combustion gas
temperatures must exceed 1800 *F at the
point of introduction, and the owner or
operator must document that adequate
oxygen is present to combust organic
constituents in the waste. See discussion
above. EPA believes that these

von Seebich. Southdown. Inc.. to Owight Hiustick.
EPA.
restrictions will, as a practical matter.
preclude use of hazardous waste in
slurry water during interim status.
Although these restrictions on
hazardous waste burned at locations
other than the hot end of an industrial
furnace do not apply under a RCRA
operating permit, the permit proceedings
will ensure that organic constituents in a
hazardous waste that is fed into the kiln
in slurry water (or in the slurry itself)
will be destroyed. The Director will
require that toxic nonmetal constituents
in the waste are destroyed to a 99.99%
destruction and removal efficiency, and
that adequate oxygen is present to
completely destroy the organic
compounds.
C. Automatic Waste Feed Cutoff
Requirements
Today's rule requires that boilers and
industrial furnaces combusting
hazardous waste be equipped with
automatic waste feed cutoff systems to
limit emissions of hazardous compounds
during combustion "upset" situations
and to ensure stable combustion
conditions. The automatic waste feed
cutoff system must be connected to the
CO and HC monitoring system, such
that an exceedance of a CO or HC limit
would trigger a cutoff of the waste feed.
Additionally, the automatic waste feed
cutoff system must engage when other
key operating conditions deviate from
specified unit operating limits, which are
determined during compliance testing or
which are based on manufacturer
specifications. See 55 266.102(e)(7)(ii)
and 266.103(g).
Some commenters disagreed with the
proposed automatic waste feed cutoff
requirements. One commenter argued
against any waste feed cutoffs for light-
weight aggregate kilns. Six commenters
expressed concern that waste feed
cutoffs would increase the instability of
the combustion conditions and would
possibly increase air emissions. Three
commenters requested a controlled
waste feed reduction over several
minutes rather than an automatic waste
feed shutoff. Three commenters
suggested different levels of CO
emissions be set for waste feed cutoffs.
The Agency acknowledges that there
can be performance and other problems
associated with automatic waste feed
cutoffs, and recognizes that they may be
undesirable for some applications. For
example, when the facility operates
without the use of hazardous waste fuel
use of fossil fuel is increased, and the
opportunity is lost for safe disposal of
hazardous waste. Further. HC emissions
may actually increase if the automatic
waste feed cutoff is triggered frequently
-------
7160 Fedanl Register / Vol. 58. No. 35 / Thursday. February 21. 1991 / Rules and Regulation*
even though combustion chamber
temperatures must be maintained while
hazardous waste or residues remain in
the combustion chamber. However, the
Agency continues to believe that
automatic waste feed cutoff systems are
necessary to avoid advene effect on
human health and the environment that
couid result if hazardous waste is fired
into the device when it is operating
under combustion upset conditions.
To address the concerns raised by
commenters, EPA recommends
installing ore-alarm systems that alert
an owner/operator of potential
problems and provide time either for
corrective measures to be taken or for a
staged cutoff of the hazardous waste
feed. Thus, the use of pre-aJarms should
minimize waste feed cutoffs. In addition,
we have included in the ruie seme
additional requirements related to waste
feed cutoffs and restarts, as discussed
below.
One commenter stated that cutoffs are
inappropriate for combustion devices
where the waste is destroyed
immediately upon injection into the
combustion chamber (e.g.. devices that
burn liquid wastes), or if the combustion
conditions supported by the waste fuel
continue to destroy residual waste after
waste feed cutoff. The Agency continues
to believe that the best method for
returning a combustion system to good
operating conditions, thereby
minimizing unacceptable emissions, is to
stop the input of hazardous waste.
Further, the burden associated with
automatic cutoffs should not be
substantial because frequent automatic
waste feed cutoffs should not occur
given that the parameters tied into the
automatic cutoff system may be
monitored on an hourly rolling average
basis (which allows high values to be
offset by low values) and that the
Agency recommends the use of pre-
alarms to warn the operator of a
pending cutotf (which may give the
operator time to take corrective
measure to avoid an automatic cutoff).
in the event of a waste feed cutoff.
monitoring for CO and HC (and other
operating parameters far which limits in
the permit are based on a roiling
averase basis) must ccnr.nue. and the
was'.s feed cannot b« restarted until CO
and HC levels (and levels of the other
parameter* i come within allowable
limits. See i 266.102(e);ri(,i). (For permit
operating conditions not established on
a roiling average basis, tr.3 Director will
specify, on a case-by-case basis, an
adequate penod of time during which
the parameters must remain within
permit limi's to demonstrate steady-
state operation prior to restarting the
hazardous waste feed.) In addition.
consistent with the April 27,1990
incinerator amendments proposal, the
provision of the final boiler and
industrial furnace rule requiring
compliance with the permit operating
conditions slates that compliance must
be maintained at any time there is waste
in the unit See 9 286.102(e)(l). This
language clarifies that activation of the
automatic waste feed cutoff does not
relieve the facility of its obligation to
comply with the permit conditions if
there is waste remaining in the unit
(such as in a rotary kiln). Thus, for
example, the air pollution control
system must continue to be operated
within the applicable permit conditions.
Furthermore, after a cutoff, the
temperature in the combustion chamber
must be maintained at levels
demonstrated during the compliance test
for as long as the hazardous waste or
residue remains in the combustion
chamber. The Agency believes this
temperature requirement will help
ensure that hydrocarbon emissions will
be minimized after a cutoff.
To comply with this requirement the
operating permit must specify the
minimum combustion chamber
temperature after a waste feed cutoff
while waste remains in the combustion
chamber. An uninterruptable burner
using auxiliary fuel (i.e., nonhazardous
waste fuel) of adequate capacity may be
needed to maintain the temperature in
the combustion chamber(s) and to allow
destruction of the waste materials and
associated combustion gases left in the
system after the waste feed is
automatically cut off. The safe startup of
the burners using auxiliary fuel requires
approved burner safety management
systems for prepurge. pilot lights, and
induced draft fan starts. If these safety
requirements preclude immediate
startup of auxiliary fuel burners and
such startup is needed to maintain
temperatures (i.e.. if the combustion
chamber temperatures drop
precipitously after waste feed cutoff).
the auxiliary fuel may have to be burned
continuously on "low fire" during
nonupset conditions.
Furthermore § 23e.lOC!e)(7)(ii)(D)
requires that the combustion gases must
continue to be routed through the air
pollution control system as iong as
waste remains in the unit. One et'fect of
this clarifying requirement, in
combination with the requirement to
maintain compliance wun permit
conditions as long as there is waste in
•he unit, is that opening of ar.y type of
air pollution control system bypass
stack while there is waste in the boiler
or furnace would be a violation of the
permit (unless the facility demonstrates
compliance with the performance
standards during the trial burn, wit)
vent stack open).
Although we believe that such
emergency bypass stacks are not
prevalent on boilers and industrial
furnaces, our discussion of this topic in
the preamble to the incinerator
amendments at 55 FR17890 (April 27.
1990) would also apply to any boiler or
industrial furnace with such a bypass or
vent stack. We received a number of
comments from the incinerator industry
expressing concern that use of a bypass
stack for safety purposes would be
considered a violation. We agree that
there can be mitigating circumstances to
warrant the use of a bypass stack and
do not discredit their use as a lafety
device. However, the Agency continues
to believe that the facility can and
should implement measures to minimize
situations where use of the emergency
vent stack is necessary.
One commenter stated that the use of
hazardous waste should be prohibited
during startup or shutdown periods for a
cement kiln until normal operating
temperatures an achieved. The final
rule does not restrict hazardous waste
burning during kiln startup or shutdown
provided that the compliance (or trial
bum) coven those periods of
operations. In other words, hazaro^vv
waste may be burned during startupTmd
shutdown if the facility demonstrates
conformance with the standards during
those operations.
Another commenter argued that
accurate measurement of combustion
chamber temperature for some
combustion devices will be difficult.
Because of this difficulty, the final rule
does not require that this temperature be
directly measured in the combustion
chamber if an owner/ operator can
demonstrate to permitting officials that
the combustion chamber temperature
correlates with a more easily measured
downstream gas temperature.
One commenter agreed with EPA's
revised proposal not to limit the number
of automatic waste feed cutoffs, but
disagreed with EPA's requirement that
combustion chamber temperatures must
be maintained at the levels that
occurred during the trail bum for the
duration of time that the waste remains
in the combustion chamber. This
commenter believed that electric utility
boilers and other burning devices will
have difficulty in accurately measuring
combustion chamber temperatures. For

temperatures be maintained. EPA
believes that the flexibility that the final
rule allows for monitoring combustion
chamber temperature and in setting the
frequency of waste feed cutoffs as
discussed above should address this
commenter's concerns.
Another commenter supported the
proposed 10 times per month limit on the
number of automatic waste feed cutoffs
and the proposed requirement that any
facility exceeding that frequency would
be required to cease burning hazardous
waste, to notify the Director, and not to
resume burning hazardous waste until
reauthorized by the Director. Another
commenter supported monthly cutoff
limits because they would provide an
incentive for the facility to take
corrective measures to preclude
frequent cutoffs. Some commer.ters
stated that this requirement is overly
restrictive.
After careful consideration. EPA has
decided to modify this requirement for
the following reasons: (1) The Agency
does not have data indicating a specific
frequency of cutoffs which would be
unacceptable at all boilers and furnaces
given that the combustion chamber
temperature and other conditions are
maintained as described above; (2) the
Agency believes that operating costs
associated with cutoffs will provide
sufficient incentive to encourage
owners/operators to minimize
automatic waste feed cutoff incidents;
and (3) the recommended use of pre-
alarm systems will reduce the number of
waste feed cutoffs. However, the final
rule allows the Director to use his
discretion to determine whether a limit
on the frequency of cutoffs is warranted
at a specific facility.
Waste Feed Restarts. Today's rule
provides that when the automatic waste
feed cutoff is triggered by a CO limit or
when applicable, an HC exceedance, the
waste feed can be restarted only when
the hourly rolling average CO/HC levels
meet the permitted limits (e.g.. 100 ppmv
for CO under Tier I).
The Agency proposed two alternative
approaches for restarting the waste feed
when a cutoff is triggered by a CO
exceedance: (1) Restart the waste feed
after an arbitrary 10-minute time period
to enable the operator to stabilize
combustion conditions: or (2) restart the
waste feed after the instantaneous CO
level meets the hourly rolling average
limit. Eight commenters supported
restarting the waste feed after the
instantaneous CO level meets the permit
limit. Five commenters suggested that
waste feed can be restarted once the
instantaneous CO level meets the hourly
roiling average limit The Agency
considered the comments, but continues
to believe that allowing a waste feed
restart after the hourly rolling average
equals or falls below the permitted limit
is preferable. After the waste feed is
cutoff, the facility will be burning
nonhazardous waste (typically fossil
fuel), which should result in CO and HC
levels well below the allowable limits.
Therefore, the hourly rolling average
should fall below the permitted limit
within a relatively brief period of time.
Allowing the waste feed to be restarted
when the instantaneous CO level has
dropped to the permitted level may not
be desirable, because restarting the
waste feed immediately may trigger
another cutoff due to a CO spike when
the waste feed is restarted.
Three commenters supported the
proposed approach to require the HC
hourly rolling average to be met before
restarting the waste feed cutoff because
of a HC exceedance. Three commenters
opposed this approach. Instead, these
commenters suggested a 10-minute
waiting period be used. EPA considered
these comments but continues to believe
that meeting the hourly rolling average
is a conservative approach and is
appropriate after a HC exceedance,
because the HC is a better surrogate for
toxic organic emissions than CO.
D. CEM Requirements for PIC Controls
The final rule promulgates the
proposed performance specifications for
continuously monitoring CO. HC, and
oxygen. See Methods Manual for
Compliance with the BIF Regulations,
incorporated as appendix IX of part 266
in today's rule. The performance
specifications for HC monitoring,
however, include specifications for both
hot and cold monitoring. Although hot
monitoring is generally required by the
final rule, cold monitoring may be used
for interim status facilities if they certify
compliance with the emissions
standards within 18 months of
promulgation of the rule. Even if cold
monitoring is used to certify initial
compliance, however, hot monitoring is
required for these facilities when they
recertify compliance and when they are
issued a RCRA operating permit
One commenter stated that an HC
monitoring system is readily available
for continuous emissions monitoring
(CEM), while five commenters
maintained that HC analyzers have
serious operational problems. Several
commenters requested that alternate HC
CEM methods be allowed, specifically
monitors with non-dispersive infra-red
(NDIR) detectors rather than the
required flame ionization detector (FID).
One commenter noted that EPA has not
validated the FID method for HC
analysis nor has it provided any critical
discussion of the current methods of HC
analysis.
The Agency considered the use of
NDIR detectors for HC monitoring but
believes that NDIR systems have
limitations compared to FID systems.
EPA believes that FID systems are more
sensitive than NDIR systems and that an
equivalent response is not found with
NDIR detectors. The final rule requires
the use of FID detectors for HC
monitoring.
Four commenters recommended
monitoring nonmethane hydrocarbons
(NMOC) as opposed to "total" HC
because methane, which is
predominately emitted from fuel
sources, has a high FID response factor.
Furthermore, these commenters would
like EPA to require testing for specific
PICs that respond poorly to HC monitors
during test burns. One commenter stated
that HC monitors can be varied easily to
detect NMOC. EPA does not agree with
either suggestion. The Agency is
requiring HC monitoring to indicate
whether the device is operating under
good combustion conditions. W«
acknowledge that the largest fraction of
organic compounds that the HC
monitoring system required by the final
rule will detect for facilities operating
under good combustion conditions will
be compounds that are relatively
nonhazardous (e.g., methane). In
addition, some hazardous compounds,
particularly highly chlorinated
compounds) will be under-reported.
Thus, although the promulgated
approach would not be adequate for the
purpose of assessing the risk that HC
may pose from a given facility, the
approach is adequate for its intended
purpose—a measure of whether the
facility continues to operate within good
combustion conditions. This is because
EPA's emissions testing has shown that
when combustion conditions
deteriorate, the compounds that are
readily detected by the promulgated HC
monitoring system increase
correspondingly.
In addition, if a NMOC system were
used, the 20 ppmv HC limit would have
to be lowered to account for the
methane fraction that would no longer
be counted. Commenters did not provide
support for so adjusting the proposed
HC limit Further, the Agency is
concerned that NMOC detectors may
not be able to provide continuous data
due to the time required for methane
separation. The Agency has also found
that HC CEMs are more durable than
NMOC CEMs. and thus less prone to
reliability problems. As a result, the
Agency has concluded that HC CEMs
are more likely to provide a continuous

indication of combustion conditions

Hot Versus Cold HC Monitoring
Systems. Except as indicated below, the
final rule requires the use of e hot or
unconditioned HC monitoring system
that must be maintained at a
temperature of at least 150 *C until the
sample gas exits the detector. See
performance specifications in Methods
Manual for Compliance with the BIF
Regulations (incorporated in today's rule
as appendix IX of part 266). Given.
however, that the technology has just
recently been demonstrated sa to be
continuously operational on hazardous
waste combustion devices, the final rule
allows the use of a conditioned gas
monitoring system during the initial
phase of interim status operations.

CO and HC within 18 months of
promulgation of the final rule may use a
conditioned gas system. Facilities that
elect to obtain the automatic 12-month
extension (or a case-by-case extension)
of the 18-month certification deadline.
however, may not use a conditioned gas
system because the additional time
provided by the extension will also
provide time to install an unconditioned
HC monitoring system. These facilities
must demonstrate compliance with the
HC limit using an unconditioned gas
monitoring system. Further, facilities
that certify initial compliance using a
conditioned gas (cold) system must use
an unconditioned gas (hot) system when
they recertify compliance within three
years of certifying initial compliance.
EPA is requiring the use of a hot
monitoring system because it represents
best demonstrated technology given that
a larger fraction of HC emissions can be
detected with a hot system. As
discussed at proposal, a hot HC
monitoring system can detect a
substantially lamer fraction of
hydrocarbon emissions than a cold
system. This is because the cold system
-.ises a eas conditioning system that
removes semi- and nonvolatile
hydrocarbons and a substantial fraction
of water-soluble volatile hydrocarbons.
EPA received numerous comments
regarding gas conditioning (heated
versus unheated) for HC monitoring.
Eiaht r.ommenters are in favor of gas
conditioning. The purpose of gas
conditioning is to remove moisture from
the combustion gases that can degrade
instruments or plug sample lines.
Sample conditioning, however, can also
remove some of the water soluble
hydrocarbons and the semi- and
nonvolatile hydrocarbons in the flue gas
such that methane and other
nonhazardous volatile hydrocarbons are
frequently the dominant constituents
measured by the detector. Some
commenters were concerned that fewer
PICs would be detected by a
conditioned (i.e., cooled) monitoring
system. However, one commenter stated
that even though the constituents
contributing most of the hypothetical
risk are relatively nonvolatile they are
relatively nondetectable through an
unconditioned (heated) monitoring
system because of their halogen content.
As discussed at proposal, the Agency
is using HC monitoring to implement the
technology-based HC limit of 20 ppmv
as an indicator of good combustion
conditions. The HC monitor ia not used
in an attempt to quantify organic
emissions for risk assessment purposes.
Emissions testing has shown that during
combustion upset conditions, both the
hot and cold HC monitoring systems
detect an increase in HC levels because
under upset conditions there is a
substantial increase in hydrocarbon
compounds that are readily detected by
either monitoring system.37
One commenter suggested that, rather
than specifying a range of 40-64 *F for
operation on the conditioner as
proposed, a specific conditioning
temperature (32 *F) should be required
to precisely define the conditioned
sampling procedure. We agree that a
minimum temperature should be
specified rather than the range. The final
rule allows a conditioned monitoring
system during the initial phase of
interim status, and requires that the
sample gas temperature must be
maintained at a minimum of 40 *F at all
times prior to discharge from the
detector. EPA selected a minimum
temperature of 40 *F from the range of 40
to 64 *F to ensure that moisture was
effectively removed from the gas sample
to preclude plugging and fouling
problems with the monitoring system.
Three commentera suggested that the
HC limit of 20 ppmv be re-examined
because gas conditioning temperatures
or other changes in the measurement

method may influence ths amount of HC
measured. Given that the 20 ppmv I
is based primarily on test burn datj
using heated (i.e., unconditioned)
monitoring systems, the Agency
considered lowering the 20 ppmv limit
when a coid (i.e.. conditioned)
monitoring system is used. (Limited field
test data indicate that a heated system
would detect from 30% to 400% more of
the mass of organic compounds than a
conditioned system.) We believe.
however, that the 20 ppmv HC limit is
still appropriate when a conditioned
system is used because: (1) The data
correlating heated vs conditioned
systems are very limited: (2) the data on
HC emissions are limited (and there
apparently is confusion in some cases as
to whether the data were taken with a
conditioned or unconditioned
monitoring system); and (3) the Agency's
risk methodology is not sophisticated
enough to demonstrate that a HC limit
of 5 or 10 ppmv using a conditioned
system rather than an unconditioned
system is needed to protect human
health and the environment Th'e SAB "
also concurs with this view. (More
detailed responses to comments on this
issue are found in a separate
background document)

Studies conducted by the Agency 40
and others 41 during development of
regulations for municipal waste
combustors (MWCs) concluded that PM
control devices operated at
temperatures greater than 450 *F have
the potential for emitting elevated levels
of CDD/CDF. At these temperatures,
precursor organic materials and chlorine
in the flue gas can be catalyzed by PM
captured in the PM collection device to
form CDD/CDF. Based on these
findings, the Agency proposed to restrict
the combustion of hazardous waste in
BIFs that operate with PM control
device temperatures greater than 450 *F.
A number of commenters opposed the
proposed limitation on the flue gas
temperature to less than 450 *F. Several
commenters pointed out technical
distinctions among types of boilers and
industrial furnaces that affect the ability
of a unit to change flue gas temperature
and the potential of an ESP to form
CDD/CDF. For example, many boiler
and industrial furnaces either combust
wastes that are very low in chlorine or
that have high levels of chlorine capture
within the process (e.g., cement kilns).

As a result the CDD/CDF emission
potential will vary for different boilers
and industrial farnanm. as well aa
between boilers and industrial furnaces
and MWCs. Commenters also stated
that there is no direct evidence of CDD/
CDF emissions from several types of
boilers and industrial furnaces, and that
compliance testing to demonstrate 99.90
percent ORE of POHCs and continuous
monitoring of CO and HC levels is
adequate to ensure minimal emissions of
organic compounds.
The Agency has reviewed the
available data on the theory of CDD/
CDF formation as well as CDD/CDF
emissions from BIFs. Based on this
review, the Agency agrees that most but
not necessarily all, BIFs burning
hazardous waste have low CDD/CDF
emission rates. For example, EPA
recently tested a cement kiln burning
hazardous waste that operates with an
ESP at a temperature of 500-500 *F and
found it to have relatively high CDD/
CDF emissions.4* (EPA conducted a risk
assessment however, that estimated the
increased lifetime cancer risk to the
hypothetical maximum exposed
individual from the CDD/CDF emissions
ranged from 7 in 10,000,000 to 2 in
1,000.000 without burning hazardous
waste and from 2 In 1,000,000 to 4 in
1.000,000 when burning hazardous
waste, well under the 1 in 100.000 limit
established in today's rule.) The Agency
suspects that the elevated CDD/CDF
concentrations in the stack gas at this
cement kiln are the result of the ESFs
operating temperature and the level of
HC precursor material in the flue gas.
HC concentrations ranged from 66 to 70
ppmv (measured with a hot system,
reported as propane, and corrected to
7% oxygen, dry basis) without
hazardous waste burning and from 38
ppmv to 63 ppmv with hazardous waste
burning. (We note that to continue
burning hazardous waste under today's
rule, the Director must establish during
the part B permit proceedings an
alternative HC level for this kiln based
on a demonstration by the applicant that
HC levels are not higher when burning
hazardous waste than under normal
conditions and that the facility is
designed and operated to minimize HC
emissions from all sources—fuels and
raw materials. At certification of
compliance with the emissions controls
other than the HC limit this facility
must also propose a HC concentration
limit for the remainder of interim status
(until that limit or another limit is
established under permit proceedings)

that will ensure that HC levels when
hazardous waste is burned will not be
higher than baseline levels (Le, HC
levels when the system is designed and
operated to minimize HC emissions from
all sources, when burning normal fuels
and feeding normal raw materials to
produce normal products, and when not
burning hazardous waste).) In addition,
trial bum emissions testing must
demonstrate that emissions of organic
compounds are not likely to result in an
increased lifetime cancer risk to the
hypothetical maximum exposed
individual exceeding 1 in 100.000. See
S 266.104(f) and discussion in section
Q.B.4.b of part three of this preamble.)
There may be other factors that
influence CDD/CDF levels at this
facility (and other facilities), but this is
uncertain. In addition, the exact HC
concentration in combustion gas below
which elevated CDD/CDF
concentrations will not occur is
unknown.
The Agency continues to believe that
the operating temperature of the PM
control device (andHC concentrations
in flue gas) plays a significant role in
CDD/CDF emissions. For a given HC
concentration in the flue gas, the
available data suggest that the potential
for elevated CDD/CDF emissions is low
if the PM control device operates at
temperatures of leu than 450 *F or
above 750 *F. Consequently, today's rule
does not require BIFs with PM control
devices operating at temperatures
outside of the 450-750 *F window to
determine CDD/CDF emission rates
(unless it is an industrial furnace with
HC levels greater than 20 ppmv).
Owners and operators of units operating
within the temperature window,
however, are required to conduct stack
testing to determine CDD/CDF emission
rates and to conduct a risk assessment
using prescribed procedures to
demonstrate that the estimated
increased lifetime cancer risk to the
hypothetical maximum exposed
individual is less than 1 in 100,000.
The Agency notes that the final rule
municipal waste combustors (MWCs)
may take a slightly different approach to
control dioxin and furans by limiting
temperatures at the inlet of the PM air
pollution control system to within 30 *F
of those achieved in a dioxin/furan
compliance test The preamble to that
rule, however, will probably continue to
note the possibility of dioxin/furan
formation in the temperature range of
230 *C (450 *F). In today's rule, the
Agency believes that using temperature
and HC levels as a trigger to dioxin/
furan testing and risk assessment will be
fully protective of human health and the

implement than the MWC approach.
ni. Risk Assessment Procedures
The Agency uses assessment of health
risk to develop and implement the final
rules for metals, hydrochloric acid (HC1),
and chlorine gas (Cla). Specifically, the
Agency has used risk assessment to: (1)
Establish ambient air concentrations of
appendix VHI compounds that do not
pose an unacceptable health risk for
purposes of this rulemaking; and (2)
establish risk-based, conservative feed
rate and emissions Screening Limits for
metals and HC1. In addition, if facilities
fail the Screening Limits or elect to
conduct dispersion modeling to obtain
less conservative limits, the rule allows
facilities to use site-specific dispersion
modeling to establish emission limits,
and ultimately feed rate limits for metals
and chlorine.
To establish health-based acceptable
ambient concentrations for
noncarcinogenic toxic metal and
nonmetal compounds (except for HC1.
Cla and lead). EPA converted oral
reference doses to reference air
concentrations (RACs) by assuming
average breathing volumes and body
weights, and by applying a safety and a
background level factor. See 54 FR at
43756. Health-based concentrations for
carcinogenic pollutants were derived by
converting cancer potency factors, or
slopes (unique for each carcinogen), into
Risk Specific Doses (RSDs) at a risk
level of 1 in 100,000.** Since carcinogens
are assumed to pose a small but finite
risk of cancer even at very low doses,
the RSD reflects a certain risk level.
corresponding to 1 chance in 100,000. or
10"* excess risk of cancer for the
maximally exposed individual if
exposed continuously to multiple
carcinogenic chemicals for a 70-year
lifetime. RACs for HCl and Cla are
based on inhalation data, and a RAC for
lead is based on the National Ambient
Air Quality Standard (NAAQS).
To establish the Screening Limits for
metals and HCl. air dispersion modeling
was applied to back-calculate maximum
acceptable feed rates and stack
emissions rates from risk-based.
acceptable ambient concentrations.
These calculations were performed for
various terrain types, effective stack
heights, and land use classifications.
The resulting permissible Screening
Limits reflect plausible, reasonable
worst-case assumptions about a generic
facility that are not site-specific. The
Screening Limits process provides a
rapid and convenient risk-based
mechanism to determine compliance.
Conservative assumptions used to
estimate health impacts exposure in the
Screening limit process include: (1) Use
of reasonable, worst-case estimate of
dispersion of stack emissions; and (2)
for the Tier I feed rate Screening Limits,
assuming that all metals and chlorine
fed into the BIF in all feedstreams are
emitted (i.e., there is no partitioning to
bottom ash or product and not removal
by an air pollution control system.44 See
52 FR 17002 (May 8,1987) and 54 FR
43729 (October 26.1989). Thus,
assumptions and the Screening Limits
tend to err intentionally on the side of
protecting human health.4*
If emission levels exceed the
Screening Limits (or if the owner/
operator so elects), the rule allows a
facility to conduct its own site-specific
air dispersion modeling in order to
establish metals. HCl. and Cb emission
limits. Incorporation of site-specific
information allows less conservative
assumptions (than the reasonable worst-
case, nonsite-specific defaults) to be
used in the dispersion models.
Consequently, site-specific air
dispersion modeling may predict lower
ambient concentrations than the
nonsite-specific modeling reflected in
the Screening Limits, thus allowing
higher emissions and feed rate limits.
A. Health Effects Data
1. Carcinogens
Health effects evaluations for
carcinogens have been summarized in
Part Three. I. D, "Evaluation of Health
Risk" in the April 27.1990 proposal (see
55 FR 17873). To summarize briefly, in
contrast to noncarcinogens. carcinogens
are assumed to present a small but finite
risk of causing cancer, even at very low
doses. The slope of the dose-response
curve in the low dose region is assumed
to be linear for carcinogens. Because of

this, the slope of the curve in the low
dose region may be used as an estimate
of carcinogenic potency. The unit risk is
defined as the incremental lifetime risk
estimated to result from exposure of an
individual for a 70-year lifetime to a
carcinogen in air containing 1 microgram
of the compound per cubic meter of air
(pg/m1). At an air concentration of 1 fig/
mj, the cancer potency slope is
numerically equivalent to the unit risk.
Thus, at a preselected risk level, the
corresponding air concentration which
would cause that risk may be calculated
by dividing the desired risk level by the
unit risk value. Although the resulting
value represents an air concentration
with units of pg/m'. this concentration
is referred to as the Risk Specific Dose
(RSD).
When exposed to more than one
carcinogen, the Guidelines for
Carcinogenic Risk Assessment (51 FR
33992 (September 24,1986)) recommend
adding risks from the individual
carcinogens to obtain the aggregate risk
(i.e.. cancer risks from exposure to more
than one carcinogen are assumed to be
additive). For today's rule, the Agency
has proposed that an aggregate risk
level for metals (i.e.. arsenic beryllium.
cadmium, and hexavalent chromium) of
10~*is appropriate because it would
limit the risk level for individual
carcinogens to the order of 10~*. The
Agency points out however, that in
selecting the appropriate risk level for a
particular regulatory program, it
considers such factors as the particular
statutory mandate involved, nature of
the pollutants, control alternatives, fate
and transport of the pollutant in
different media, and potential human
exposure. See. e.g.. 54 FR at 38049 (Sept.
14,1989). Particular factors bearing on
the Agency's choice here include the
wide array and potentially large
volumes of carcinogenic pollutants that
can be emitted by these devices (unlike
the situation in such rules as the
benzene NESHAP when a single
pollutant with well-understood effects
was at issue), the need to guard against
environmental harm as well as harm to
human health, potential synergistic
effects of the carcinogens emitted by

1990, influences the Agency'* choice of a
conservative risk target in this rule.
These same factors can also influence
'choice of a risk level where the Agency
is making site-specific determinations.
The following section discusses
comments on health effects data on
carcinogens.
o. Unit Risk Factors/Risk Specific
Doses. A few commenters argued for
deletion of category C carcinogens from
consideration in the risk assessment
process.
Given that the carcinogenic metals
arsenic, beryllium, cadmium, and
hexavalent chromium are classified as
either A or B carcinogens, this
discussion pertains only to the C
nonmetal appendix VIII compounds for
which the Agency established KT'RSDs
for purposes of implementing the low
risk waste exemption, risk assessments
for cement kilns with HC levels
exceeding 20 ppmv, and health-based
limits for Bevill excluded waste.
As a conservative element in the risk
assessment process, and especially for
purposes of implementing an exemption
from some of the emission controls, EPA
does not believe that exposure to
category C carcinogens should be
ignored at this time for those chemicals
with cancer potency slopes. The
classification schemes categorize
^chemicals based upon weight of the
levidence. not carcinogenic potency.
"Therefore, a highly potent carcinogen
may be classified in the C category and
present a threat to health.
b. Quality of the lexicological Data
Base. Several commenters questioned
the quality and extent of the toxicology
data base and EPA's selection of
specific studies used to calculate the
cancer potency factors and unit risk
values for a particular chemical. For
example, one commenter noted that the
molecular species of a metal compound
emitted from an incinerator may be
markedly different from the metallic
complex actually tested for
carcinogenicity and used to calculate
that metal's cancer potency factor. This
would distort the risk assessment
process. This same commenter argued
that beryllium oxide, which would be
formed preferentially at the extreme
temperatures of a furnace, is relatively
inert compared to the molecular
complex of beryllium which forms the
basis of the cancer potency factor.
Another commenter contended that in
general the less water soluble (and.
therefore, less bioavailable) metallic
oxides are emitted from incinerators
whereas the metallic species tested for
cancer were more water soluble and
jbioavailable (i.e.. absorbable into the
'organism).
EPA acknowledges the concern that
the metal complex tested for
carcinogenicity in animal* reflects that
to which humans are exposed. However,
the particular metal complex being
emitted may not have been tested in
animals. In such cases, it is sometimes
necessary to use that toxicologicai data
which is available (on the same metal
but complexed with a different ligand),
limitations notwithstanding, until
appropriate data on the complex of
concern become available. EPA believes
the use of the available data base will
result in risk assessment methodology
that is protective of human health and
the environment.
Moreover, EPA notes that soluble
metallic salts may also be emitted under
some conditions (e.g., metallic
chlorides). For screening purposes, the
conservative assumption that soluble
(i.e., bioavailable) metallic complexes
are emitted, is assumed to protect
health. For the site-specific risk
assessment option, historical or test
burn data may be used to identify
probable emitted metallic species. If
permit officials conclude during the
permit process that appropriate fate,
transport and toxicologicai data exist
for the actual emitted complex to
support risk assessment this could then
be used in the site-specific risk
assessment option.
c. High DOM to Low Dose
Extrapolation. Several commenters
questioned the scientific merit of
extrapolating from high dose
experimental data to low dose cancer
risks using existing statistical models,
asserting that the process is not
biologically-based and is extremely
conservative (i.e.. overly health-
protective): Two commenters asserted
that the linearized multistage model
should not be applied to non-genotoxic
carcinogens because such "carcinogens"
promote rather than initiate cancer, thus
acting as a classical toxicant with a
threshold. These commenters
maintained that a chemical such as
chloroform, which they claim is non-
genotoxic (i.e., has not tested positive in
mutation assays), would have a
threshold below which there is no risk
of cancer. Another commenter argued
that biological evidence indicates •
threshold for arsenic-induced cancer
due to its known benefit as an essential
trace element at low doses. This same
commenter asserted that hexavalent
chromium (Cr+6) is quickly converted
in the body to the essential trace
element Cr+3 and. therefore, should be
treated as a "threshold carcinogen."
The Agency is following closely
recent developments in scientific
consensus regarding the basic molecular
biology of cancer. EPA will revise its
guidelines for carcinogen risk
assessment and other guidance
documents, to reflect developing
scientific theory on high to low dose
extrapolation threshold effects, and
other related issues. Until that time. EPA
will continue to use its current
approach, believing that a more
conservative approach is warranted in
the face of uncertainty.
d. Chromium Oxidation State. Several
commenters argued that the current
proposal does not differentiate
chromium in the +8 oxidation state
from chromium +3. They contend that
most chromium emitted from boilers.
industrial furnaces, and incinerators
exists in the +3 state. Consequently, the
proposed approach, which assumes that
all chromium is +8. may overstate risks
drastically. The commenters
recommended that EPA assume that
only a fraction of the chromium emitted
by incinerators exists in the +6
oxidation state.
EPA concludes that assuming that
100% of the chromium is in the
hexavalent oxidation state is •
conservative assumption taken in the
face of limited data. In a test •• of
hazardous waste incinerator emissions
under varying levels of total chlorine in
the waste burned, a high percentage of
the total chromium emitted was in the
hexavalent state under certain
conditions. Until more data is available.
showing consistently lower proportions
of Cr** under a variety of combustion
conditions, EPA believes it is health-
protective to assume that chromium
from incinerator emissions exists in the
hexavalent state. Facilities may elect to
conduct emissions testing to determine
the actual emission rate of Cr*'.
e. Additive Ritkt. One commenter
criticized EPA's selection of 10~* as the
acceptable aggregate risk level (for
carcinogenic metals) for deriving
screening limits, and claimed the
selection is arbitrary and inconsistent
with other EPA policy. EPA policy, the
commenter notes, has traditionally
embraced a range of risks from 10~' to
10~4, with the final EPA-selected risk
level dependent upon site-specific
conditions (i.e., characteristics and size
of the exposed population).
EPA's rationale for selecting 10~* risk
for the MEI is described in the October
26,1980 supplemental notice (54 FR
43754). In summary. EPA continues to
believe that the aggregate cancer risk to

-------
7168 Federal Register / Vol. 56. No. 35 / Thursday, February 21. 1991 / Rules and Regulations
the MEI of 10~* for metals is appropriate
because: (1) It provides adequate
protection of public health: (2) it
considers weight of evidence of human
carcinogenicity; (3) it limits the risk from
individual Group A and B carcinogens to
risk levels on the order of 1CT*: and (4) it
is within the range of risk levels the
Agency has used for hazardous waste
regulatory programs. See also the
discussion in section III.A.l of part three
above.
2. Noncarcinogens. For toxic
substances not known to display
carcinogenic properties, there appears to
be an identifiable exposure threshold
below which adverse health effects
usually do not occur. Noncarcinogenic
effects are manifested when these .
pollutants are present in concentrations
great enough to overcome the
homeostatic. compensating, and
adaptive mechanisms of the organism.
Thus, protection against the adverse
health effects of a toxicant is likely to be
achieved by preventing total exposure
levels that would result in a dose
exceeding its threshold. Since other
sources in addition to the controlled
source may contribute to exposure.
ambient concentrations associated with
the controlled source should ideally take
other potential sources into account.
Therefore, the Agency has
conservatively defined reference air
concentrations (RACs) for
noncarcinogenic compounds that are
defined in terms of • fixed fraction of
the estimated threshold concentration.
The RACs for lead and hydrogen
chloride, however, were established
differently, as discussed below. The
RACs established in today's final rule
are identical to those proposed. (See
appendix H of the Supplement to
Proposed Rule at 54 FR 43762 (October
26.1989)). (The Agency notes that it
does not intend for RACs to be used as
a means of setting air quality standards
in other contexts. For instance, the RAC
methodology does not imply a decision
to supplant standards established under
the Clean Air Act)
We note, however, that the RACs
proposed in appendix H of the
supplement to proposed rule (and
promulgated today as appendix IV to
the rule) included both Agency-verified
and unverified values. Unverified values
are subject to revision as the Agency's
Reference Dose Workgroup continues to
establish verified inhalation RfDs.
(Occasionally, the Agency may also
revise verified values based on new and
significant information.) Since the
supplemental notice, the Workgroup has
established inhalation RfDs for eight
compounds on proposed appendix H
(and promulgated appendix IV to the
rule). The basis for the newly-verified
RfDs is set forth in the Health Effects
Assessment Summary Tables. Fourth
Quarter—FY90, U.S. EPA. OERR 9200 6-
303 (90-4). September 1990.*7
Consequently. RACs based on those
RfDs are different from the proposed
and promulgated RACs. The RACs
based on verified inhalation RfDs are
shown in the table below. EPA will use
the omnibus permit authority of
§ 270.32(b)(2) to use these revised RACs
where the facts warrant.**

RACs have been derived from oral
reference doses (RfDs) for those
noncarcinogenic compounds listed
appendix VIII of 40 CFR part 261 (except
for lead. HC1. and Cli) for which the
Agency considers that it has adequate
health effects data. An oral RfD is an
estimate (with an uncertainty of perhaps
an order of magnitude) of a daily oral
dose (commonly expressed with units of
mg/kg-day) for the human population
(including sensitive subgroups) that is
likely to be without an appreciable risk
deleterious effects, even if exposure
occurs daily for a lifetime. Since these
oral RfDs are subject to change. EPA
will undertake rulemakings as necessary
if the derivative RACs change in a way
that affects the regulatory standard (see
also the discussion of this issue in the
Boiler/Furnace supplemental notice
published on October 26.1989 at 54 FR
43718). We note that in the interim
before any such rulemaking is complete.

and as discussed above, permit officials
may use the omnibus permit authority *•
of the statute to consider revised hea
effects data in establishing permit
conditions.
The Agency's rationale for using oral
RfDs as a basis for RAC-derivation is
described in 54 FR 43755 (October 26.
1989). EPA believes the approach to
derive RACs is reasonable because: (1)
the RfDs are verified by an EPA
workgroup whose decisions are subject
to public review: (2) the verification
process addresses long term (lifetime)
exposure: (3) the RfDs are based on the
best available information meeting
specific scientific criteria; (4) the most
sensitive individuals are considered:
and (5) the RfD determination takes into
account the confidence in the quality of
the information on which they are
based. Nevertheless, the Agency's
Inhalation RfD Workgroup is developing
reference dose values (concentrations)
for inhalation exposure for several
chemicals, and some an currently
available. As reference concentrations
are established by the Workgroup, the
Agency will consider the need to change
the RACs established in today's rule as
discussed above.
The final rule regulates HC1 emissions

term) RAC of 7 »ig/m».»° The RAC jj

resulting from exposure to HC1.
Background levels were considered to
be insignificant given that there are not
many large sources of HCl and that this
pollutant generally should not be
transported over long distances in the
lower atmosphere.
The Agency also proposed a short-
term (i.e.. 3-minute exposure) RAC for
HCl. The Agency agrees with
commenters. however, that the proposed
RAC was not technically supportable.
See discussion in section V of part three
of this preamble. Consequently, the final
rule does not establish a short-term RAC
for HCl.
To consider the health effects from
lead emissions, we adjusted the
National Ambient Air Quality Standard
(NAAQS) by a factor of one-tenth to
account for background ambient levels

^and indirect exposure from the source in
•question. Thus, although the lead
FNAAQS is 1.5 fig/ms, for purposes of
this regulation, sources could contribute
only up to 0.15fig/m*. Given, however.
that the lead NAAQS is based on a
quarterly average, the equivalent annual
exposure is 0.09 WJ/m*.
Finally, section 109 of the Clean Air
Act (CAA) requires EPA to establish
ambient standards for pollutants
determined to be injurious to public
health, allowing for an adequate margin
of safety. Secondary NAAQS, also
authorized by section 109, must be
designed to protect public welfare in
addition to public health, and, thus, are
more stringent. As discussed above, the
Reference Air Concentration (RAG)
used in today's rule for Lead is based on
the Lead NAAQS. As the Agency
develops additional NAAQS for toxic
compounds that may be emitted from
hazardous waste incinerators, we will
consider whether the acceptable
ambient levels (and, subsequently, the
feed rate and emission rate Screening
Limits) ulimately established under this
rule should be revised. We note again
that the reference air concentration
values (and risk-specific dose values for
carcinogens] presented here in no way
preclude the Agency from establishing
wAAQS as appropriate for these
^compounds under authority of the CAA.
a. Derivation of Oral RfDs/HACs.
Many commenters responded to the
issue of derivation of oral RfDs/RACs.
questioning the scientific basis for the
oral RfDa and conversion of RfDs to
RACs. Some commenters stated that use
of oral RfDs do not factor in differences
in routes of exposure (e.g., absorption,
first-pass effects) when extrapolating
from oral to inhalation routes of
exposure. As discussed above, we
acknowledge the limitations of
developing RACs from oral RfDs but
coniinue to believe the approach used is
reasonable and the best available
approach until the Agency's Inhalation
RfD Workgroup can provide inhalation
values.
Other commenters directed their
comments exclusively to lead, indicating
that the lead RAC was arbitrary. EPA
has based the lead RAC on the National
Ambient Air Quality Standard
(NAAQS). This was done in part
because no reference dose or cancer
potency slope is currently available for
this metal. The final rule uses 10%,
rather than 25% as is used for other
compounds, as an apportionment factor
Has proposed) because the Agency is
particularly concerned with: (1) The
possible high contribution of lead
exposure by indirect pathways,
particularly in urban environments; and
(2) the growing concern of low level lead
exposure in children since the Isad
NAAQS was established. (The Agency
currently plans to propose to readjust
the lead NAAQS in 1991.)
b. Apportionment. Some commenters
questioned EPA's proposal apportioning
75% of the RfD to other non-specified
sources, thus causing the RAC to
correspond to 25% of the RfD. The
commenters indicated that the figure of
75% from other sources was arbitrary
and could vary from one chemical to
another. They suggested that unless
other sources of exposure were
identified, the RAC should reflect 100%
of the RfD.
EPA has chosen a fraction (25%) of the
RfD to serve as the basis for the RACs
because indirect pathways, known to
contribute to risks, are not quantified in
these regulations. Even apart from
exposures contributed by sources
separate from the boiler, industrial
furnace, or incinerator, indirect
pathways from emissions from these
devices themselves may contribute 75%
or more to risk. Such indirect (i.e., non-
inhalation) pathways include deposition
of emitted chemicals on: (1) Gardens
and crops directly consumed by
humans: (2) meadows used for grazing
by beef cattle and other edible livestock;
and (3) meadows and fodder used by
dairy cattle (and subsequent milk
consumption by humans).
Such real exposures, which are not
quantified in these rules, are accounted
for by the allowance for 75%
contribution from other sources.
Moreover, it is questionable whether
any single facility should be allowed to
consume 100% of an individual's
exposure allowance, above which any
further exposure might cause adverse
health effects.
B. Air Dispersion Modeling
The Agency used air dispersion
modeling to develop the Screening
Limits and dispersion modeling is
available as the exposure assessment
component of the site-specific risk
assessment option. A more extensive
discussion of air dispersion modeling is
included in the 1939 supplemental notice
(see 54 FR 43752-54). This discussion
focuses on derivation of Screening
Limits wherein the dispersion models
are used to "back-calculate" emission
rates from acceptable ground level
concentrations. The section is also
applicable to dispersion modeling used
for the risk assessment option (where
ground level concentrations are
predicted from estimated emissions
rates). The reader is referred to this
discussion for further information about
air dispersion modeling. It should be
noted that for the purposes of the risk
assessment option, more site-specific
information may be used in place of
some of the conservative default
assumptions used to derive the
Screening Limits, generally resulting in
lower predicted ambient air
concentrations.
1. Option for Site-Specific Modeling
In responding to this provision in the
proposal, many commenters argued for
procedures which would allow greater
flexibility in the air dispersion modeling
process. Many commenters seemed to
confuse the issues of dispersion
modeling used for the Screening Limits.
and modeling for the site-specific risk
assessment. EPA concedes that many
assumptions used to develop the
Screening Limits are, by design,
conservative to ensure that the Limits
are protective in most cases. These
assumptions do not apply, however,
when an owner or operator conducts
site-specific dispersion modeling under
the Tier in standards. For site-specific
dispersion modeling, procedures
specified in EPA's Guideline on Air
Quality Models must be used.
2. Terrain-Adjusted Effective Stack
Height
Two commenters stated that in
adjusting the stack height to account for
local terrain and differentiating for
terrain in the screeing limits, EPA is
"double counting" the influence of
terrain unnecessarily. One commenter
added that such terrain adjustment of
stack height is not supported by the
current EPA Guideline on Air Quality
Models (Revised) and should be
eliminated.
EPA acknowledged this "double
counting" of terrain in the supplement to
the proposed rule (54 FR 43759), stating
that this additional conservatism is
necessary to account for the wide range
of terrain complexities encountered at
real facilities. EPA continues to believe
that this double counting is necessary.
Without this conservatism, additional
criteria would have to be added to the
existing list (see 1266.106(b)(7)) for
determining when the screening limits
may not be conservative and, thus, may
not be used. Commenters did not
propose (and provide support for)
additional criteria for determining when
the use of less conservative screening
limits would be appropriate. Further.
EPA believes that additional criteria
would complicate and delay the
implementation of the rule by placing
additional burden on regulatory
officials. Moreover, if a facility cannot
-------
7166 Federal Register / Vol. 56, No. 35 / Thursday, February 21. 1991 / Rules and Regulations
meet the screening limits, then site-
specific dispersion modeling may be
used to demonstrate compliance with
the Tier III standards. Detailed.
comprehensive dispersion modeling
generally costs less than $5,000 and,
thus, should not pose a substantial
burden. In fact many BIPs have already
conducted such modeling to comply
with applicable standards under the
Clean Air Act. Finally, the final rule
minimizes the burden of dispersion
modeling by allowing the use of
screening models.
3. Conservatism in Screening Limits
Five commenters stated that EPA's
approach to setting the screening limits
ia overly conservative and illustrated
this by calculating the difference in
estimated ground level concentrations
using site-specific information as
opposed to the default assumptions
recommended for the Screening Limits.
It should be noted that the Agency
would expect that the use of site-
specific information would lead to
higher emission limits than under the
screening limits. However, the Agency
developed feed rate and emission rate
screening limits with the intent of
minimizing the need of site-specific
dispersion modeling and thus reducing
the burden of demonstrating compliance
with the emissions standards. To ensure
that the limits are protective in most
cases, however, the Agency derived the
limits using conservative assumptions.
The Agency believes that although the
assumptions are reasonable, they would
likely limit emissions by a factor of 2 to
20 times lower than would be allowed
by site-specific dispersion modeling (54
FR 43758).
4. CEP Stack Height.
Two commenters stated that EPA
should not impose a CEP stack height
limitation for existing stacks. The
commenters went on to state that EPA.
should allow modeling of emissions at*
actual stack height for existing stacks
or. at a minimum, adopt a grandfather
provision to exclude GEP from applying
to stacks constructed prior to December
:i. 1970. One commenter also indicated
that EPA should recognize that the stack
height used for conducting a site-specific
dispersion modeling analysis may
exceed CEP formula height, as allowed
under section 123 of the Clean Air Act
The Agency maintains that in
complying with the metals and HC1/C1*
controls credit will not be allowed for
slack heights greater than GEP. GEP
stack heights are determined in a
nanner consistent with the Guideline
for Determination of Good Engineering
Practice Stack Height (Technical
Support Document for the Stack Height
Regulations), Revised (EPA 450/480-
023R).
EPA's position here is consistent with
the prohibition on using physical stack
height in excess of GEP in the
development of emission limitations
under EPA's Air Program at 40 CFR
51.118 and 40 CFR 51.164. Stack heights
higher than GEP cannot be used for
compliance purposes because such
stacks merely provide added dispersion
and dilution of ambient levels. EPA
prefers that pollutants be removed from
the stack gas to avoid build-up of
persistent pollutants (e.g., metals) in the
environment and subsequent indirect
exposure through, for example, the food
chain. In addition, better dispersion of
emissions of carcinogenic compounds
can merely expose larger populations to
(albeit lower) concentrations of
pollutants and may not decrease the
aggregate population risk (i.e.. cancer
incidents/year in the affected
population).
5. Plume Rise Table
One commenter recommended that
EPA extend Table F-2 (plume rise) and
Tables E-l through E-10 (feed rate and
emissions screening limits) of the
October 26.1989 supplemental notice to
account for the high flow rates typical of
many cement plant stacks. Another
commenter stated that the effective
stack height of most utility boilers
exceeds the maximum stack height
contained in Tables E-l through E-10.
One commenter indicated that the
plume rise values presented in Table F-
2 are not conservative for conditions of
neutral atmospheric stability at average
to high wind speeds or for stable
atmospheric conditions at all typical
wind speeds. This commenter added
that the screening limits based on Table
F-2 plume rise may not be conservative
for regions having complex terrain.
For the final rule, the plume rise
values presented in Table F-2 of the-
supplement to the proposed rule were
revised and the table was expanded to
include higher stack exit flow rates
indicative of cement kiln stacks (exit
flow rates were increased up to a level
of 200 ma/s). See appendix VI to the
final rule. The plume rise table values
were originally developed based on
plume rise equations presented in the
1979 User's Guide to the Industrial
Source Complex (ISC) model. The plume
rise formulation in the ISC model has
since been changed to correspond to the
way other EPA models determine plume
rise. Consequently, the entire table was
revised, based on conservative
application of the updated neutral and
stable buoyant plume rise equations.5'
The revised values of plume rise
represent the lowest value of
conservative stable buoyant and neutral
buoyant plume rise for each flow rate/
temperature level.
The range of terrain-adjusted effective
stack heights, shown in Tables E-l
through E-10 of the supplemental notice.
was not increased beyond the height of
120 meters. This height was determined
to be the maximum terrain-adjusted
effective stack height based on the stack
parameter and site location data used in
the development of the dispersion
coefficients (as described in appendix F
of the proposed, supplemental rule).
Facilities with terrain-adjusted effective
stack heights that exceed 120 meters
have the option of conducting site-
specific dispersion modeling to
demonstrate compliance.
6. Compliance by Manipulating Effective
Stack Height
One commenter claimed that facilities
may elect to circumvent compliance by
manipulating their effective stack
heights. This commenter added mat
additional exposures could result from
the increased dispersion from taller
stacks. The Agency acknowledges that
an owner or .operator could increase
physical stack height up to the GEP
maximum to achieve better dispersion
and hence a higher allowable emission
rate. The Agency maintains, however,
that it is more protective of human
health and the environment (see
discussion in section IH.B.4 above) and
it may be more cost-effective to upgrade
emission control equipment to state-of-
the-art control, rather than to increase
stack height, particularly given that the
Agency plans to consider in the future
whether additional controls are needed
to better control metals emissions. See
discussion in section I of Part Three of
this preamble.
7. Effect of HC1 Emissions on Acid Rain
One commenter disagreed with the
use of Screening Limits for HC1 which
are based solely upon effective stack
height terrain and land use. This
commenter maintained that this
approach ignores the effects of HC1 in
atmospheric reactions and acid rain.
Addressing potential effects of HC1 in
atmospheric reactions and acid rain is
beyond the scope of this rule. The
screening limits were developed to

8. Building Wake Effects
One commenter stated that emissions
limits based on effective stack height,
terrain, and land use would not be
conservative in cases where stacks are
subject to building wake effects. This
commenter added that only
consideration of building wake effects
will lead to conservative concentrations
for stacks influenced by nearby
structures and recommended that site-
specific dispersion modeling be required
in all cases where the "Guideline for Air
Quality Models (Revised)" indicates the
necessity for consideration of building
wake effects.
The development of the conservative
dispersion coefficients incorporated an
eleventh hypothetical source in order to
represent facilities whose release
heights do not meet good engineering
practice and whose plumes would thus
be subject to building wake effects (54
FR 43752). In addition, the Agency
acknowledges that the dispersion
coefficients used to establish the Tier 1
and II Screening Limits may not be
conservative in extremely poor
dispersion conditions or when the
ambient-air receptor is located close to
.the source and has therefore defined
five situations for which the permit
writer should require site-specific
dispersion modeling (34 FR 43754).
Furthermore, the Agency is reserving the
right tc require that a site-specific
dispersion modeling analysis be
conducted, irrespective of whether the
facility meets the specific Screening
Limits. Thus, the permit writer has the
option of overruling use of Tier I or II. if
a probability exists that application of
this methodology would not be
protective of the health-based
s'andards. The Tier III approach of
conducting site-specific dispersion
modeling requires incorporation of
building wake effects, as necessary, in
the modeling analysis. The Tier I and 0
Screening Limit methodology was not
further modified to account for these
factors, as it already embodies repeated
use of conservative assumptions.
C. Consideration of Indirect Exposure
and Environmental Impacts
1. Ir. direct Exposure
During the proposal stages of these
regulations, a few commenters
recommended incorporating indirect
exposure pathways into the risk
assessment process. Indirect exposure is
defined, in these regulations, as any
exposure pathway other than direct
inhalation of emissions from • boiler or
industrial furnace. One commenter
maintained that emissions such as
metals, chlorinated dioxins, and furans
would be environmentally persistent
and able to enter the food chain after
deposition on the ground (including
crops, pasture land, surface waters).
Consequently, the commenter argued
that indirect exposures should be
factored into the risk assessment.
EPA recognizes that the contribution
of indirect pathways may be significant.
However, the Agency believes that other
conservative procedures, such as
apportioning 75% of exposures to either
indirect pathways or other emission
sources (that can contribute to
background levels) in the calculation of
RACs, will help offset the contribution
of indirect pathways. Another
significant source of conservatism.
offsetting the contribution of indirect
pathways, is represented by the inherent
uncertainty, and consequent
conservatism, in the models used to
estimate unit risk values. Use of the MEI
in the Screening Limits procedure
comprises yet another conservative
element in the risk assessment process
which would offset direct estimation of
indirect pathway exposure. Therefore.
the Agency has not modified the risk
assessment process to address indirect
pathways.
2. Non-human Health Related
Environmental Impacts
One commenter noted that for many
pollutants, environmental standards for
certain flora and fauna may be more
stringent than for humans. Therefore,
the effect on non-human receptors
should not be ignored in the regulations
and the environmental risks should be
evaluated.
EPA is concerned about the potential
effects of BIF emissions on non-human
receptors. While some environmental
standards are available for the
protection of environmental receptors
(notably EPA water quality criteria for
aquatic organisms), methods for
quantifying exposure and defining
acceptable levels for non-human
receptors are still largely in the
developmental stages. Thus, until these
critical procedures are better
established, the Agency is not requiring
such an evaluation at this time.
However, as noted earlier, some of the
conservatism in the human health risk
assessment is designed to compensate
for the absence of direct environmental
standards.
D. Acceptable Risk Level for
Carcinogens
Today's rule limits the incremental
lifetime cancer risk to the hypothetical
maximum exposed individual (MEI) to
10~*. This risk level is within the range
of levels historically used by EPA in its
hazardous waste and emergency
response programs—10"4 to 10" *.
Under the rule, we are limiting the
aggregate risk to the MEI from
carcinogenic metals to 10~*. and the
aggregate risk from carcinogenic organic
compounds (dioxins and furans and
other PICs under provisions of the
alternative HC limit) to 10~*. This will
limit in most cases the risk from
individual carcinogenic compounds to
levels on the order of 10~* but below
10~*. The rule does not require that the
risk from carcinogenic organic
compounds be added to the risk from
carcinogenic metals. This is because the
Agency does not believe it is
appropriate to sum the risk from metals
(i.e., arsenic, beryllium, cadmium, and
chromium) that are known or probable
human carcinogens (Group A or B
carcinogens under the weight-of-
evidence approach) with the risk from
organic compounds, many of which, are
possible human carcinogens (Group C
carcinogens).
In selecting a 10" * aggregate risk
threshold level for this rule, we
considered risk thresholds in the range
of 10~* to 10'4, the range the Agency
generally uses for various aspects of its
hazardous waste programs.
We considered limiting the aggregate
risk of the MEI to 10~* but determined
that this risk threshold would be
unnecessarily conservative for the
purpose of this rule. In reaching this
determination, we considered that, at an
aggregate risk level of 10"*, the risk level
for individual metals would be on the
order of 10"', which we believe is overly
conservative for this rule.
Alternatively, we considered limiting
the aggregate risk to the MEI to 10~4. An
aggregate risk threshold of NT'would
result in limiting the risk level for
individual carcinogens on the order of
10~*. We did not select a 10~* aggregate
risk threshold for this proposed rule for
a number of reasons. In selecting the
appropriate risk level for a particular
regulatory program, the Agency
considers such factors as the particular
statutory mandate involved, nature of
the pollutants, control alternatives, fate
and transport of the pollutant in
different media, and potential human
exposure. The Agency believes that a
10" • risk level is appropriate for this rule
because: (1) The rule limits emissions
considering only direct exposure via
inhalation of dispersed emissions. Other
routes of exposure (e.g., soil ingestion,
uptake through the food chain) are not
accounted for by this methodology,
-------
7170 Federal Register / Vol. 56, No. 35 / Thursday, February 21. 1991 / Rules and Regulations
which means the risk is somewhat
higher. (2) the carcinogenic metals that
the rule controls are Group A or B (i.e..
known or probable) human carcinogens;
(3) we are concerned about the potential
risks posed by the unknown pollutants
these devices can emit—i.e., products of
incomplete combustion (PICs);5* and (4)
ths 10"' risk level does not result in a
PJ •: that poses a substantial burden on
th< regulated community given that it is
neither a. major rule as defined by
Executive Order 12291 nor will it
significantly impact small entities.
When the proposed regulations were
published and comments were solicited
from affected parties, several
commenters responded to the issue of
acceptable risk levels for exposure to
carcinogens. These commenters
questioned the basis of 10"' as
representing an acceptable risk level.
They maintained that the discussion in
the rule, serving as the rationale or
justification for selecting this level of
risk, was inadequate. Others- asserted
that the selected acceptable level of
cancer risk was not consistent with
other regulations (specifically. 10-~4
cancer risk to the MEI was used to set a
national emission standard (NESHAP)
for benzene, and 10~* for individuals
living "some distance from the source").
The Agency continues to believe that
the aggregate cancer risk to the MET of
l

categories of waste combustion
facilities.)
Many commenters responded broadly
on the impact of assumptions and
uncertainty in risk assessment. While
generally supporting the concept of risk
assessment some asserted that EPA's
proposed assumptions were too
conservative regarding estimated
emission levels, dispersion modeling.
and health impact estimation. Further,
they maintained that assumptions were
not well enough justified and the
conservative bias used for each of the
multiple assumptions required in a risk
assessment tends to accumulate,
resulting in gross over-estimation of
health impacts. Some of the specific
assumptions that commenters
considered too conservative are
discussed in the following paragraphs.
Two commenters asserted that
emission control technology should not
be assumed absent when estimating
emission levels. One commenter
recommended that sensitivity analysis
be incorporated into the risk assessment
process. This commenter also
recommended incorporation into the risk
assessment of population mobility (i.e..
time spent away from the site), facility
lifetimes less than 70 years, and an
attenuation factor for time spent
indoors, rather than assume 24 hr/day,
70-year exposure.
Many of the respondents argued that
economic impacts resulting from overly-
conservative risk assessments are
substantial To avoid some of the
default assumptions is also burdensome
in the commenters' judgment requiring
trial burns, emissions measurements,
slag and product assays, and detailed
air quality dispersion modeling.
Although many of the assumptions
discussed by the commenters are
conservative in nature, it is difficult to
determine how leas conservative
assumptions could be used in light of the
considerable associated uncertainty.
Much of the conservatism referred to
originates from assumptions used to
derive screening levels. When screening
levels are derived, either (1) No site-
specific information is available (nor
may be assumed if the procedure is
intended to screen a variety of sites); or
(2) incorporation of site-specific
information in the derivation of
screening levels would so complicate
the process as to render it prohibitively
time-consuming and defeat its utility as
a screen. Thus, in light of the uncertainty
(i.e.. no site specific-information),
conservative assumptions are used to
derive the screening limits that EPA
believes to be protective of human
health and the environment
If the facility fails to meet the
screening criteria, the option of site-
specific risk assessment is still
available. For site-specific risk
assessment more realistic and less
conservative assumptions may be
incorporated, reflecting actual site or
facility conditions.
V. Controls for Emissions of Toxic
Metals
The Agency has identified 12 toxic
metals in appendix VIII of 40 CFR part
261 that may pose a hazard to human
health and the environment: antimony,
arsenic, barium, beryllium, cadmium,
hexavalent chromium, lead, mercury,
nickel, selenium, silver, and thallium.
Five of these metals (or their
compounds) are known or suspected
carcinogens: arsenic, beryllium.
cadmium, hexavalent chromium, and
nickel.
Many of these toxic metals are
contained in hazardous waste that is
burned in boilers and industrial
furnaces. Many hazardous waste fuels
contain metals at levels orders of
magnitude higher than levels found in
No. 6 fuel oil Metal-bearing wastes
typically used as fuel in boilers and
industrial furnaces include spent
halogenated and nonhalogenated
degreasing solvents used for metals
cleaning, paint manufacturing wastes,
and other organic liquid wastes with
high heating values. Currently, metals
emissions from the burning of these
wastes are not controlled under RCRA
for boilers and the types of industrial
furnaces that burn hazardous wastes.
Emissions of carcinogenic metals can
potentially result in increased lifetime
cancer risks of greater than IX10"* and
emissions of noncaicinagenic metals
such as lead can result in ambient levels
that result in adverse health effects.
Today's final rule promulgates the
controls as discussed in the October
1989 supplement to the proposed rule
(see 54 FR 43728-29)." See 1266.106.

10 metals that could reasonably be
expected to be in the waste. The metals
excluded from analysis must be
indentured and the basis for their
exclusion explained to ensure that there
is adequate justification for not _

The standards are implemented
through a three-tiered approach.
Compliance with any tier is acceptable.
The tiers are structured to allow higher
emission rates (and feed rates) as the
owner or operator elects to conduct
more site-specific testing and analyses
(e.g., emissions testing, dispersion
modeling). Thus, the feed rate limits
under each of the tiers are derived
baaed on different levels of site-specific
information related to facility design
and surrounding terrain. Under tier I
(see i 286.106(b)), the Agency has
provided conservative waste feed rate
limits in reference tables as a function of
effective stack height and terrain and
land use in the vicinity of the stack The
owner or operator demonstrates
compliance by waste analysis, not
emissions testing or dispersion
modeling. Consequently, the Tier I feed
rate limits an based on an assumed
reasonable, worst-case dispersion
scenario, and an assumption that all
metals fed to the device are emitted (i.e.
no partitioning to bottom ash or product.
and no removal by an air pollution
control device (APCD)).

developed conservative emission rate
limits in reference tables, again as a
function of effective stack height and
terrain and land use in the vicinity of the
stack. The Agency also assumed
reasonable, worst-case dispersion under
Tier II.
Under Tier III (see § 266.10S(d)), the
owner or operator elects to conduct
emissions testing and site-specific
dispersion modeling to demonstrate that
the actual (measured) emissions do not
exceed acceptable levels considering
actual (predicted) dispersion.
The metals controls apply both to
facilities applying for a part B operating
permit and to facilities operating during
interim status. See section VII of part
Three of this preamble for discussion of
how the standards apply during interim
status.
A. Background Information
The following sections summarize
EPA's regulation of metals emissions
from boilers and industrial furnaces
under other statutes, the 1987 proposed
rule and comments received on that
proposal, and the basis for the 1989
revision to the proposed rule and
comments received on that revised
approach.
1. Metal Standards Under Other Statutes
As discussed below. EPA has
promulgated standards applicable to
boilers and industrial furnaces under
other statutes for some but not all of the
13 toxic metals controlled by today's
rule. Under the Clean Air Act (CAA),
EPA established National Emissions
Standards for Hazardous Air Pollutants
(MESHAPS) for arsenic, beryllium, and
mercury for certain categories of sources
(»0 CFR part 81). These emission
standards were developed considering
the quantities and types of metals
emissions from various source
categories, current control practices, and
the economic impacts of reducing
emissions. In addition. EPA has
established National Ambient Air
Quality Standards •• (NAAQS) for lead
and paniculate matter. These ambient
standards are implemented by states
under the State Implementation Plan
(SIP) program to control major sources
of lead and paniculate emissions. Hie
Agency does not believe that lead
emissions standards have been
" We nott that the reference tit concentration

Air Act.
established under the SIPs for any
boilers and for many industrial furnaces
that burn hazardous waste fuels (e.g.,
cement and light-weight aggregate kilns)
because they are not major lead emitters
as defined under the NAAQS. Therefore.
EPA believes that today's metals
controls are not redundant to existing
Agency standards, and. thus, are
necessary to ensure adequate protection
of human health and the environment.
Participate emission standards.
however, established under the SIPs in
confonnance with the paniculate.
NAAQS, or by EPA as New Source
Performance Standards (NSPS). do
apply to some boilers and industrial
furnaces that bum hazardous waste.
The paniculate standards generally limit
metals emissions to the extent that
state-of-the-art paniculate control
technologies will allow. High efficiency
electrostatic precipitatora (ESPs) or
fabric filters are usually required to
meet these standards. However, these
paniculate emission standards may not
adequately control metals emissions
from the burning of hazardous wastes in
many boilers and industrial furnaces for
service reasons: (1) The particulate
standards do not apply to gas and oil-
fired boilers (which represent a large
number of hazardous waste fuel
burners); (2) smaller coal-fired boilers
are not subject to NSPS standards and
may not be required under the SIPs to be
equipped with ESPs or fabric filters: (3)
large volumes of hazardous waste fuels
are burned by light-weight aggregate
kilns that are equipped with low-
pressure wet scrubbers that may not be
highly efficient at collecting particulates
in the less than 1 micron range, the size
range that contains the bulk of the
particulate metals: and (4) the risks
posed by metals emissions from these
boilers and industrial furnaces that are
equipped with ESPs. fabric filters, and
wet scrubbers can increase
substantially when hazardous waste
fuel is burned since the levels of some
metals, particularly chromium and lead.
can be much higher in hazardous waste
than in coal.
2.1987 Proposed Rule
The 1987 proposed rule would have
established a four-tiered standard to
control emissions of arsenic, cadmium.
hexavalent chromium, and lead. Each
tier represented a standard protective
on its own. and demonstration of
compliance with any Tier would have
been sufficient Tiers I through III
established hazardous waste metals
concentrations, feed rates, and emission
screening limits, respectively, as a
function of device type and thermal
capacity. Tier IV would have provided
for site-specific dispersion modeling to
demonstrate that when the screening
limits were exceeded, emissions would
nevertheless not pose an unacceptable
health risk. Data available to the
Agency indicated that only four of the 12
toxic metals listed in appendix VIE of
part 281 were likely to be present in
hazardous waste burned in boilers and
industrial furnaces at levels posing a
significant health risk. The permit writer
would have determined on a case-by-
case basis if any of the other toxic
metals were present at levels posing a
significant risk.
Public comments submitted on the
1987 proposal stated that EPA's
database on the metals composition of
hazardous waste was both limited and
out of date in light of the Agency's data
collection efforts at that time and the
HSWA statutory requirement to pretreat
waste that heretofore had been land
disposed. As a result of HSWA. more
hazardous waste is being burned, and
pretreamtent operations are often likely
to involve combustion. The hazardous.
waste burned currently and in the future
in boilers and industrial furnaces may
include toxic metals other than the four
targeted for regulation in the 1987
proposal. Therefore, the Agency
requested comment in the October 1989
supplemental notice on expanding the
list of regulated metals to include all 10
appendix Vffl metals. (Nickel and
selenium were not included as discussed
above.) In addition, if standards for all
of the toxic metals were included in the
rule, the burden on permit writers would
actually be reduced because explicit
standards would be provided for all
metals of potential concern. Without
explicit standards, permit writers would
have to rely on the omnibus permit
authority of the statute to add permit
conditions as necessary to protect
human health and the environment
Using the omnibus permit authority can
involve a lengthy and cumbersome.
interaction between permit officials and
the applicant
3.1989 Supplement to Proposed Rule
Based on public comments submitted
on the 1987 proposed rule and on
additional evaluation of the risk
assessment approach used for the
proposal, the Agency discussed in the
1989 supplemental notice whether to (1)
expand the list of metals for which
emissions standards would be
established in the rule to include all the
toxic metals listed in appendix VIII of
part 261 (except nickel and selenium, for
the reasons discussed above); (2)
establish the screening limits as a
function of effective stack height

terrain, and land use rather than as a
function of device type and capacity;
and (3) rather than provide the screening
limits in the rule itself as proposed in
1987, provide them in a guidance
document that would be entitled "Risk
Assessment Guideline (RAG) for
Permitting Hazardous Waste Thermal
Treatment Devices".
a. Expanded List of Metals. In the
1989 supplemental notice. EPA proposed
to expand the list of metals for which
emissions standards would be
established in the rule to include
antimony, arsenic, barium, beryllium.
cadmium, hexavalent chromium, lead.
mercury silver, and thallium. Thus, of
the 12 toxic metals listed in appendix
VIII. only selenium and nickel would not
be controlled for reasons discussed
above. Today's final rule establishes
standards for all 10 metals. We note that
the controls apply only to metals that
are present in the hazardous waste feed
at detectable levels using procedures
specified in SW-846. See { 286.106(a).
b. Revised Basis for Screening Limits.
In the 1989 supplemental notice. EPA
also proposed to revise the bases for the
feed rate and emission rate screening
limits to correlate them with stack
height and terrain and land use in the
vicinity of the facility because these
parameters more directly relate
emission controls to key parameters that
affect the dispersion of emissions, and
ultimately, ambient levels (i.e.. more so
than the proposed approach of
correlating the screening limits to device
type and heat input capacity). When
developing the Tier I through Tier III
screening limits proposed in 1987. the
Agency made a simplified assumption
that effective stack height correlated
with thermal capacity (e.g., if the
thermal capacity of one device was 10
percent greater than the thermal
apacity of another, the effective stack
height was also 10 percent greater). The
Agency acknowledges that this
assumption may not always hold. Stack
helflht is often more a function of the
height of nearby buildings and
surrounding terrain than a function of
:he heat input capacity of the device.
Thus, the fmal ru;e correlates the Tier I
.2iid Tier i! screening limits to stack
height, terrain, and land use.
c. Establishing the Screening Limits in
:i-e Rule. As originally proposed in 1987.
the iinal rule incorporates the Tier 1 feed
rate screening limits and the Tier II
emissions race screening limits in the
rule itseif rather than in a separate
guidance document. Our concern (and
many commenters concurred) is that a
guidance document would not earn- the
'.veight of a regulation—permit writers
would be free to accept or reject the
guidance (i.e., in this case, the screening
limits and the reference air
concentration (RACs) and risk-specific
dose (RSD) values used to develop the
limits). In addition, permit writers would
be obligated to justify use and
appropriateness of the guidance on a
case-by-case basis. This would place a
substantial burden on the permit writer
and result in inconsistent and perhaps.
inappropriate permit condition!. Finally,
implementing the emission standards
during interim status as required by the
final rule would be virtually impossible
without incorporating the screening
limits and RACs and RSDs in the rule.
We note that revisions to the RACs
and RSD values will undoubtedly need
to be made over time as the Agency
obtains additional health effects
information on the regulated pollutants.
and corresponding revisions to the
screening limits will be made by formal
ruiemaking (i.e., proposed revisions.
opportunity for pubu'c comment and
promulgation of final revisions). In the
interim, however, permit writers may
apply stricter limits than contained in
the rule (if the facts justify it) pursuant
to the omnibus permit authority ** in
section 3005(c)(3).
In the 1989 proposal as a possible
alternative to monitoring waste feed
rates and compositions. EPA requested
comment on using the results of
analyses of emission control residues to
monitor compliance with the metals
emission standards. Several
commenters supported this approach.
The final rule allows for this or other
alternative approaches to implement the
metals controls. See section 1V.C.4 of
Part Three of the preamble.
B. How the Standards Work
1. Tier III Standards
Tier HI standards are discussed first
because the Agency believes that the
majority of facilities will elect to comply
with these standards rather than the
Tier I cr Tier II screening limits to obtain
more flexible permit limits. The Tier III
standards (see § 26B.108(d)) require: (1)
Emissions testing to determine actual
emissions taking into account
partitioning of metals to combustion gas
versus ash or product: and removal of
metals from flue gas by the air pollution
control system (APCS): and (2) site-
specific dispersion modeling to take into
account actual, predicted dispersion
conditions at the facility.
To comply with the Tier ffl standards,
predicted ambient concentrations of the
carcinogenic metals, arsenic, beryllium.
cadmium, and hexavalent chromium at
the hypothetical maximum exposed
individual (MET) may not result in an
increased cancer risk of more than 1 in
100.000. The risk from each metal must
be summed to ensure that the summed
risk does not exceed 1 in 100.000. As
proposed, the final rule establishes a
risk-specific dose (RSD) for each metal
at the 10-* (i.e.. 1 in 100.000) risk level. If
a person is exposed to the 10~6 RSD (an
ambient air concentration) over a
lifetime, the probability of increased
cancer incidence is not expected to
exceed 1 in 100.000. To ensure that the
summed risk from the four carcinogens
is no greater than 1 in 100.1)00, the ratios
of the predicted ambient concentration
to the 10~* RSD must be summed for all
metals to demonstrate that the sum does
not exceed l.O.*7
For the noncarcinogenic metals.
antimony, barium, mercury, silver, and
thallium, predicted MEI ambient air
concentrations may not exceed the
reference air concentrations (RACs), as
proposed The RAC for lead is based on
10% of the National Ambient Air Quality
Standard (NAAQS) for lead, as
proposed. One commenter stated that
the lead RAC may be appropriate for
facilities in urban areas but that it is not
appropriate for rural areas with low
background lead levels. This commenter
suggested a waiver of the lead RAC
where a facility can show that measured
ambient air lead levels do not exceed
the NAAQS. Although this approach is
reasonable, the final rule does not
include a waiver provision for the lead
RAC based on site-specific ambient air
monitoring ** because: (1) the lead

(OAQPS) would make this approach
impracticable: (3) a waiver provision
would add extra complexity to the rule;
and (4) such a waiver would make
eventual further regulation under
amended section 112 of the Clean Air
Act more likely.
a. Emissions Testing. Stack emissions
tasting for metals must be conducted in
conformance with "Methodology for the
Determination of Metals Emissions in
Exhaust Gases from Hazardous Waste
Incineration and Similar Combustion
Processes" (Multiple Metals Train)
provided in section 3.1 of Methods
Manual for Compliance with the BIF
Regulations (incorporated in today's rule
as appendix IX of part 266).
b. Dispersion Modeling. Dispersion
modeling must be conducted in
conformance with EPA's "Hazardous
Waste Combustion Air Quality
Screening Procedure" provided in
Methods Manual for Compliance with
the BIF Regulations or EPA's Guideline
on Air Quality Models (Revised) which
are incorporated in today's rule as
Appendices IX and X. respectively, of
Part 2C6, or "EPA SCREEN Screening
Procedure" as described in Screening
Procedures for Estimating Air Quality
Impact of Stationary Sources. The latter
document is incorporated by reference
in today's final rule at { 260.11. The
Guideline on Air Quality Models is the
Agency's primary guide for dispersion
modeling. The "Hazardous Waste
Combustion Air Quality Screening
Procedure" is included in EPA's
Guidance on Metals and Hydrogen

hazardous waste combustion facilities.
is also included in that document The
data base used in the derivation is the
same as that used for deriving the Tier I
and Tier II screening limits as
summarized in the October 26.1989
supplement to the proposed BIF rule (54
FR 43752). Finally, the EPA SCREEN
screening procedure has been in general
use since 1988 when it was developed
by EPA's Office of Air Quality Planning
and Standards. It has been used by
Regional Offices, States, and sources for
air dispersion modeling required by EPA
air regulations.
If a user determines that there is an
inconsistency between either of the
screening procedures discussed above
and EPA's Guideline on Air Quality
Models, the Guideline shall have
primacy.
c. CEP Stack Height As proposed.
stack heights used to demonstrate
conformance with the final rule may not
exceed Good Engineering Practice (GEP)
as defined in 40 CFR part Sl.lOO(ii).
d. MEL As proposed, the hypothetical
MEI concentration is the maximum
annual average ground level
concentration at an off-site location. On-
site MEI locations need not be used to
demonstrate conformance with the
standards, unless a person resides on-
site.
e. Bubble Approach for Multiple
Stacks. Given that the standards for
metals (and HC1 and Cl») are health risk-
based, the final rules are implemented
using a limited "bubble" approach at
proposed. Under the limited bubble
approach, emissions from all hazardous
waste combustion stacks at a facility
subject to metals and chlorine feed rate
limits must be considered in
demonstrating conformance with the
acceptable ambient levels. This includes
all boilers and industrial furnaces
regulated under today's rule, and also
those RCRA-regulated incinerators and
thermal treatment units where feed rate
or emission limits have been established
for metals, chlorine. HC1, or Cli by EPA.
(The Agency considered expanding the
bubble to consider other stack emissions
such as from nonhazardous waste
incinerators or process stacks, out
believes that effective implementation
would be difficult given the different
types and levels of regulatory control
end procedures applicable to a variety
of stack emission sources.)
To implement the bubble approach.
dispersion modeling must consider
emissions from all regulated stacks (see
discussion above) to predict the
maximum annual average off-site
ground level (i.e.. MEI) concentration of
each metal. The MEI location will
generally vary for each metal.
2. Tier II Standards
See 5 266.106(c). The final rule
incorporates the Tier II emission rate
screening limits (see appendix I of the
final rule) as presented in the 1989
supplemental notice as a function of
terrain-adjusted effective stack height
and noncomplex versus complex terrain •
and urban versus rural land use in the
vicinity of the facility. The limits were
back-calculated from the RACs and 10~*
RSDs established by today's rule using
reasonable, worst-case dispersion ^
scenarios. Conformance with the Tier !•
emission rate screening limits is
demonstrated by emissions testing (i.e..
the facility's actual emissions are
compared to the maximum allowable
screening limits).
The methodologies for determining
terrain-adjusted effective stack height
and terrain type are established in
§5 266.106(0) (3) and (4), and the
methodology for determining land use in
the vicinity of the stack are provided in
"Simplified Land Use Classification
Procedures for Compliance with Tier I
and Tier n Limits in Methods Manual for
Compliance with the BIF Regulations
(incorporated in today's rule as
appendix IX of part 266).
a. Special Requirements for
Carcinogens. We note that the Tier II
emission rate screening limit* for the
carcinogen metal* arsenic, beryllium.
cadmium, hexavalent chromium, are
back-calculated from the 10~* RSD for
each metal. Thus, if the actual emission
rate of one of those metal* was at the
Tier II screening limit the resulting risk
to the MEI is estimated to be 1 in
100,000. Given that the rule require* that
the summed risk for all carcinogenic
metals cannot exceed 1 hi 100,000. the
ratio* of the actual emission rate to <
Tier II allowable emission rate for all i
the carcinogenic metals must be
summed and the sum cannot exceed 1.0.
b. Bubble Approach for Multiple
Stacks. Although we believe that most
facilities will use Tier III dispersion
modeling to demonstrate conformance
with the metals (and HC1 and Cl.)
controls when they have multiple stacks
to obtain credit for actual dispersion
conditions. Tier II (or Tier I) may be
used. To use the Tier I feed rate limits or
Tier II emissions rate limits for multiple
stacks, the owner/operator must
conservatively assume that all
hazardous waste is fed to the source
with the worst-case stack (i.e..
considering dispersion). The worst-case
stack must be determined from the
following equation *• as applied to each
stack:

c. Facilities Ineligible To Use the Tier
11 (and Tier I) Screening Limits. The
screening limits wen back-calculated
from the RACi and NT* RSDs
established by today'i rule using
dispersion modeling scenarios that the
Agency considers reasonable, worst-
case dispersion scenarios. However,
dispersion characteristics at a particular
facility may, in fact provide worse
dispersion of emissions than used to
calculate the screening limits.
Consequently, the final rule, as
discussed in the 1989 supplemental
notice, establishes criteria for facilities
that are ineligible to use the screening
limits. See { 266.106(b)(7).
3. Tier I Standards
See 4 266.106(b). The final rule
incorporates the Tier I feed rate
screening limits (see appendix 1 to the
rule! as presented in the 1989
supplemental notice as • function of
terrain adjusted effective stack height
and noncomplex versus complex terrain
and urban versus rural land use in the
vicinity of the facility. Conformance
with the Tier I feed rate screening limits
is demonstrated by sampling and
analysis of all feed streams (hazardous
waste, other fuels, and raw materials).
By complying with the conservative
Tier 1 feed rate screening limits.
applicants burning hazardous waste
with very low concentrations of metals
would not have to conduct emissions
testing. The feed rate limits are back-
calculated from the emission screening
limits, assuming that all metals present
in feedstreams an emitted to the
atmosphen. Thus, no metals an
assumed to partition to the bottom ash
or product and no allowance is made
for removal of metals from the stack gas
by an air pollution control system.
Consequently, the Tier 1 feed rate
screening limits an equivalent to the
Tier II emission rate screening limits
and are provided in the same table in
appendix I to the rule. (At proposal the
feed rate and emission rate screening
limits were provided in separate tables
because the Agency presented the limits
m different units—Ib/hr (pound per
hour) for feed rate limits, and g/s (grams
per second) for emission rate limits. To
avoid confusion and for simplicity.
however, the final rule combines the
Tier I and II screening limits and
presents the limits in g/hr (grams per
hour)).
The Tier II discussions above on
special requirements for carcinogens
also applies to the Tier 1 feed rate limits.
Thus, to demonstrate conformance with
the feed rate limits for the carcinogenic
metals, the sum of the ratios of the
actual feed rate to the Tier I allowable
feed rate for all of the carcinogenic
metals must be summed, and the sum
cannot exceed 1.0.
In addition, the Tier II discussions
above on the bubble approach for
multiple stacks and criteria for facilities
that are ineligible to use the screening
limit apply to the Tier I feed rate
screening limits as well.
Finally, we note that the Tier I feed
rate limits may be adjusted upward to
reflect site-specific dispersion modeling.
This is a hybrid of Tien I and IE. See
$ 266.106(e). Under this approach, site-
specific dispersion modeling may be
conducted using the procedures
discussed above to back-calculate
allowable emission rates for each metal.
These allowable emission rates then
become the adjusted feed rate limits.
Given that emissions testing is not
conducted under this modified Tier I
approach, no credit is given for
partitioning of metals to bottom ash or
product or removal by the air pollution
control system.
C. Implementation
As discussed above, EPA developed a
three-tiered standard to ensure that
metals emissions do not pose an
unacceptable risk to human health and
the environment Tier I consists of
conservative feed rate screening limits.
Tier II establishes conservative emission
rate screening limits, and Tier in allows
the use of site-specific air dispersion
modeling to demonstrate compliance.
The decision of which tier to use
depends on the physical characteristics
of the facility and surrounding terrain.
on the anticipated waste compositions
and feed rates, and on the level of
resources available for conducting the
analysis. It is acceptable to use. different
tiers to comply with the standards for
different metals.
1. Tier I Implementation
The Tier I feed rate limits are
implemented by sampling and-analysis
as necessary and flow rate monitoring
of each feedstream (i.e.. hazardous
waste, other fuels, and raw materials) to
ensure that the total feed rate of each
metal does not exceed the Tier I limit on
either an hourly rolling average or
instantaneous basis (i.e., at any time),
except as provided for the carcinogenic
metals and lead as discussed below.
a. Special Procedures for
Carcinogenic Metals. Given that for the
carcinogenic metals, the sum of the
ratios of the actual feed rates to the Tier
I allowable feed rates cannot exceed 1.0,
there an no fixed feed rate limits for
individual carcinogenic metals. Rather,
the operator must ensure that on an
hourly rolling average or instantaneous
basis (or as allowed below for
carcinogenic metals and lead) that the
mixture of carcinogenic metals fed into
the BIF does not exceed allowable
levels. To demonstrate conformance
with this standard, the operator must (1)
Know the concentration of metals in
each feedstream and the Dow rate of
each feedstream: (2) calculate on an
hourly rolling average or instantaneous
basis (or as allowed below for
carcinogenic metals and lead) the sum
of the ratios of the actual feed rate to
the allowable feed rate; and (3) ensure
that the sum of the ratios for all
carcinogenic metals (on an hourly
rolling average or instantaneous basis or
as allowed below) does not exceed 1.0.
b. Averaging Periods. As discussed in
the 1989 supplemental notice, the final
rule provides an alternative averaging
period to the hourly rolling average or
instantaneous basis for the carcinogenic
metals arsenic, beryllium, cadmium, and
chromium, and for lead. For these*
metals, an averaging period not to
exceed 24 hours (i.e.. 24-hour rolling
average) may be used provided that the
feed rate at any time (Le.,
instantaneously) does not exceed 10
times the feed rate on an hourly rolling
average basis. The Agency believes that
an averaging period greater than an
hourly rolling average is reasonable
given that the metals controls an based
on lifetime exposures. However, the
Agency is concerned that averaging
periods greater than 24 hours may be
difficult to enforce. A ten-fold higher
emission rate should not pose adverse
health effects from short-term exposures
for the carcinogenic metals because the
24-hour rolling average would not
exceed the level that could pose • 10'*
health risk over a lifetime of exposure
and the threshold (i.e.. noncancer)
health effect would not be likely at
exposures only ten times higher than the
10~* RSD. A ten-fold higher
instantaneous ambient level for lead
should not pose adverse health effects
given that the acceptable ambient level
for long-term exposure to lead (i.e.. the
lead RAC) is based on only 10% of the
National Ambient Air Quality Standard.
We do not believe that • similar
approach for the other noncarcinogenic
metals would be appropriate given the
uncertainty in the level of protection
provided by the long-term acceptable
ambient (e.g.. the RACs are based on
oral RfDs converted 1 to 1 to inhalation
values).

2. TferD ImplementatioB
Confonnance with the Tier II emission
rate screening limits is based on
emissions testing (see section IV.B.l.a)
using the Multiple Metals Train
prescribed in Methods Manual for
Compliance with the BIF Regulations
(incorporated in today's rale as
appendix IX of part 280}. The Tier II
emission limits are implemented by
permit limits on the following
parameter* based on operations during
the trial burn:
• Maximum feed rate of each metal in
total feedstreams (e.g.. hazardous waste.
raw material, other fuel), except a»
discussed below
• Maximum feed rate of each metal in
total hazardous waste feedatreamr
• Maximum feed rate of each metal in.
all pompabie hazardous waste
feedstreams;
• Maximum feed rate of total

hazardous waste:
• Maximum feed rate of chlorine in
total feedstreams;
• Maximum production rate in
appropriate units (e.g.. total heat input
pounds of steam prodcced. raw material
feed rate);
• Maximum temperature at the inlet
to the air pollution control system
(APCS);
• Maximum, combustion chamber
tempeiaturer and
• Key parameters to ensnre proper
operation of the APCS.
The approach that most be used to
measure these parameters and the
approach to establish limits on each
parameter based on trial bum data is
specified in f 208.102(e)(6r.
In addition, the permit must specify
sampling and analysis procedure* far alt
feedstreams and all flow rates of all
feedstreams must be continuously
monitored and recorded.
The final rule establishes limits on
these parameters because they can
affect metals esoisaion*. The feed rate of
metals in both total hazardous-wasta
feeds and pumpable hazardous1 waste
feeds is limited because the physical
form of the waste (e.g, solid vs liquid)
can affect the partitioning of the mttal
between bottom ash, (for a boiler) or
product (for a furnace) and. combustion
gas entering the PM control system.
Metals partition to the combustion gas
more readily when fired in a liquid or
pumpable form.
The rale limits the metal feed rate
from total feedstreams to account for
metals in raw materials and
nonhazardons fuels. When added to the
emissions from hazardous waste.
r.oncarcinogenic metals from these
source* can cause the MB
concentration to exceed the threshold
level for health effects and carcinogenic
metals from these source* can cause the
MEI concentration to exceed the
incremental lifetime cancer risk limit for
the rule of 1 in 100.000. Thus, these
controls ensure that banting hazardous
waste does not result in unacceptable
risk*.
The rule limits the chlorine feed rata
because chlorine can increase the
volatility of metals, thus increasing the
rate of partitioning to the combustion

3. Tier III Implementation
Confonnance with Tier III is
demonstrated by emissions testing and
site-specific dispersion modeling
showing that ambient levels of metals
do not exceed allowable levels. Permit
limits are established for the same
parameters as required for Tier D.
4. Special Requirements for Furnace*
that Recycle Collected Paniculate
Matter
Metal emissions are not feasibly
monitored on a continuous bam. Thnss
soow other means of demonstrating
canpfisnee is necessary. For neat type*
of BIT* compliance is demonstrated by
monitoring feed rates of metals front all
feedstreams. EPA requested comment
on- whether approaches other than
monitoring feed rates of metala may be
more appropriate to implement the
metals controls. See 54 FR 43760-(Oct
26,1980). A aumber of commenters
argued that the material balance
approach for implea*Bting the metal*
control* was impractical and
nonconaervative for cement kirn*. The
material balance approach for metals
limits the feed rate of each metal in
three types of feeds: (1) Pumpabie
hazardous waste; (2> total haurdou*
waste; and (3) total feedstreams.
Although limiting the feed rata of each
metal in the total hazardous waste feed
and the pumpable hazardous waste feed
was workable, commenters argued that
limiting the feed rate of metals in total
feedstream* wa* impractical for cement
kilns because of the variety of raw
materiel* they feed. Raw material* to- a

Of avun more concern, to the Agency*
however, is the fact that the matBrial

total hazardous waste, recycled dust
and total feedstreams would be limited.)
We did not adopt this approach
because: (1) The recycled dust is an
internal recycled stream so that limits
on the recycled dust coupled with limits
on other feedstreams would probably
correlate with metals emissions in the
kiln off-gas, but not necessarily with
stack emissions; and (2) during an
emissions test when metals are spiked.
the system will not be in equilibrium
and we do not know enough about metal
behavior in the system to determine
whether the metals feed rate in the dust
would be higher or lower after reaching
equilibrium (i..e., we did not know
whether this approach would be
conservative).
To address this concern that the
material balance approach to
implementing metals controls is not
likely to be conservative (i.e., protective)
for furnaces that recylce dust, today's
rule requires owners and operators of
such devices to comply with one of three
alternatives: (1) Daily monitoring of
ed PM to ensure that metals
do not exceed limits that relate
centration of the metal in the
collected PM to emitted PM; (2) daily
stack sampling for metals; or (3)
conditioning of the furnace system prior
to compliance testing to ensure that
metals emissions are at equilibrium with
metals feed rates. We discuss each of
these procedures below.
We note first however, that today's
rule gives owners and operators the
option of selecting one of these methods
only during interim status. The Director
will determine under the part B permit
application proceeding which of these
methods (or whether another method)
may be more appropriate on a case-by-
case basis considering the facts. See
§ 266.106(f). In addition, we note that
experience with these methods during
interim status may indicate the need to
refine them for use under a RCRA
operating permit Finally, we note that
'.his provision of the permit standards is
not limited to furnaces that recycle
collected PM. (However, the methods
discussed below may be used during
interim status only by furnaces that
recycle collected PM.) The permit
standards provide this flexibility
because, although we believe that these
^ethods (as they may be refined with
Hcperience) or other methods that
adequately address the concerns
described below must be required for
systems that recycle collected PM. the
first two methods (i.e., monitoring
collected PM or daily stack sampling)
may be preferable for other types of
devices as well. This is because these
first two alternative methods address
not only the special problem caused by
recycled PM but also the problem of the
difficulty (and imprecision) associated
with limiting metals emission rates by
the material balance approach given the
variability of waste and raw material
matrices and variability of the
concentrations of metals in feedstreams.
a problem that also exists for these
furnaces and will exist for other devices
as well.40
a. Monitoring Metals in Collected PM.
This approach will control metals
emission rates by establishing limits on
all of the parameters discussed above
for implementing the Tier n and Tier m
controls, except for limits on the feed
rate of each metal in total feedstreams.
In lieu of that parameter, the final rule
limits the concentration of each metal in
collected PM. See "Alternative
Methodology for Implementing Metals
Controls" in Method Manual for
Compliance with the BEF Regulations
(incorporated in today's rule as
appendix IX of part 266). The
concentration limit is calculated by
determining the maximum allowable
concentration of each metal in the
emitted PM and by empirically relating
the concentration of the metal in the
emitted PM to the concentration of the
metal in collected PM (i.e., the
enrichment factor). The maximum
allowable concentration of each metal
in the emitted PM is determined by
dividing the allowable emission rate for
the metal in pounds per hour by the
applicable PM standard " in pounds per
hour. The enrichment factor (i.e..
concentration of a metal in emitted PM
divided by the concentration in
collected PM) is determined initially by
a series of 10 emissions tests over a two-
week period. Quarterly testing is
required thereafter to determine if the
enrichment factor changes substantially.
If so. the series of 10 emissions tests
must be conducted again to establish the
revised enrichment factor.
EPA acknowledges certain potential
limitations to this approach: (1) The
Agency has limited data to support the
main assumption of this approach—that
the enrichment factor will remain
constant over the range of normal
operating conditions that occur between
the initial series of 10 tests to establish
the enrichment factor and the quarterly
confirmation teats; and (2) that a
problem with emissions is detected after
the fact However, we have built into the
approach conservative features that
should address concern about whether
the enrichment factor may change over
time. First, the approach assumes that
the facility is always operating at its
maximum allowable PM emission limit
Although allowable metal
concentrations in collected PM would be
higher when the facility operates at
lower PM emission levels, the limits do
not change. Thus, for example, for every
10% the facility operates under its PM
standard, the limit on metals
concentrations in collected PM are
conservative (lower than necessary) by
10%. Second, the enrichment factor is
statistically determined based on test
data as the lower of: (1) Twice the
enrichment factor at the 95% confidence
level: or (2) the enrichment factor at the
99% confidence level. Where then is .
significant scatter in the data, twice the
enrichment factor at the 95% confidence
level is likely to govern. Thus, when the
enrichment factor varies significantly
during the 10 tests, not only is the
enrichment factor based on the 95%
confidence level but an additional
margin of safety is provided by doubling
the factor at the 95% confidence level for
purposes of determining the metal limit
in collected PM."
As for detection after the fact
sampling of collected dust is required
every eight hours to form a daily
composite sample. The operator is
allowed up to 48 hours to analyze the
daily composite '* given that the
analytical procedures can take 24 to 48
hours even for on-site laboratories. In
addition, if the sample fails the
concentration limit for a metal, the
operator may analyze two duplicate
samples that he may have elected to
obtain to determine if the failed sample
is an outlier. Analyses of these back-up
samples will also take up to 48 hours.
Thus, it could take up to four days to
confirm that a dust sample has failed the

status compliance testing) is required to
demonstrate the performance
capabilities of a system and to establish
the operating limits of a facility for the
duration of the operating permit.
Compliance limits will be based on the
operating conditions and emission rates
observed during the trial burn.
Therefore, to obtain the most flexible
compliance limits, an owner/operator
should conduct test burns and the trial
burn under worst-case conditions (those
that maximize emissions without
exceeding the established limits). These
conditions include feeding the waste
used in the trial bum at a feed rate and
metals concentration that reflect the
highest levels expected in present or
future operations.
Spiking with Metals. To achieve the
maximum allowable concentration of
metals, the owner/operator may wish to
spike the waste to artificially high
concentrations of the metals during the
pre-trial burn period and during the trial
burn. However, the owner/operator may
not feed metal* at levels higher than
those documented in the part B permit
application as those not likely to result
in emissions exceeding allowable levels.
Permit officials will consider this
documentation in establishing pre-trial
bum permit conditions for new permits.
6. Monitoring and Analysis
Requirements
a. Emissions Testing. Emissions
testing and analysis for metali must be
conducted using "Methodology for the
Determination of Metal Emissions in
Exhaust Gases from Hazardous Waste
Incineration and Similar Combustion
Processes" provided in Methods Manual
for Compliance with the BIF
Regulations ". incorporated in today's
rule as appendix IX of part 266. The
methodology describes the use of a
multiple metals sampling train. The
methodology also describes and
provides references to the appropriate
analytical techniques in Test Methods
for Evaluation Solid Wastes (SW-846).
incorporated by reference in { 260.11.
that must be used to analyze samples.
b. Analysis of Feedstreams.
Feedstrcams must be analyzed for each
of the 10 regulated metals that could
reasonably be expected to be in the
hazardous waste. If a particular metal is
excluded from the analysis, the basis for
exclusion must be documented and
included in the operating record.
Methods for sampling and analysis of
feedstreams for metals are prescribed in
SW-646.
D. Interim Status Compliance
Requirements
As prescribed in $286.103. and
discussed in section VII of part three of
this preamble, boilers and industrial
furnaces operating under interim status
must comply with the metals emissions
standards during interim status.
V. Controls for Emissions of Hydrogen
Chloride and Chlorine Gas
Today's final rule uses a three-tiered
regulatory approach to limit HC1 and CU
emissions (see i 268.107), an approach
identical to that used to control
noncarcinogenic toxic metals emissions.
A. Background Information
In the 1987 proposed rule. EPA stated
its intention to develop risk-based HC1
emission standards in the same format
and for the same reasons as the
proposed metals emission limits. The
HC1 emission limits for a particular
device would have been based on the
device type and capacity, and on the
type of surrounding terrain. In the 1989
supplemental notice. EPA discussed an
alternative approach to make the
standards a function of stack height
terrain, and land use rather than a
function of device type and capacity.
The reasons for the change were the
same as those described above in the
discussion of the metals standards.
Controls on CU were proposed on
April 27.1990 (55 FR17866) because CU
can be emitted from devices burning
chlorinated wastes if insufficient
hydrogen is available (i.e.. from other
hydrocarbon compounds or water
vapor) to react with all of the chlorine
present in the waste. In recent tests *T of
a cement kiln. EPA found that
approximately 50% of gaseous chlorine
emissions were in the form of CU (and
the other 50% was in the form of HC1). In
the April 1990 proposal the Agency
proposed a CU RAC of 0.4 ug/ra *.
In the 1989 supplemental notice. EPA
also discussed the possibility of using
continuous HC1 monitors in lieu of the
waste feed analysis approach for
monitoring HC1 emissions are likely to
be close to allowable emissions. The
Agency continues to believe that this is
a reasonable approach and believes that
it can be effectively implemented during
the permit process as necessary using
the omnibus authority.**
B. Response to Comments
The Agency received a number of
comments on the proposed HC1 and CU
controls as discussed below.
1. Short Term Hd RAC
A number of commenters stated that
the Agency's support for the proposed 3-
minute RAC for HC1 was inadequate.
The Agency is currently developing a
new methodology for evaluating health
effects data to develop a no-adverse-
effect short-term exposure level.**
Given that the new methodology has not
been approved by the Agency, today's
final rule does not establish a short-term
RACforHCl.
We note that the Tier I chlorine feed
rate limits proposed in the 1989
supplemental notice were based on the
short-term HC1 RAC because the short-
term exposure RAC provided more
restrictive feed rate limits than the long-
term RAC Consequently, the 1989
proposed chlorine feed rate limits are
not included in today's final rule. In
establishing the Tier I feed rate limits
for chlorine in today's final rule, the
Agency considered both the long-term
HC1 RAC (i.e. 7 ug/m *) and the dt
RAC (i.e.. 0.4 fig/m »). and the
partitioning between the two pollutants
in stack gases. Given that the Agency
has tested for CU emissions at only two
facilities, and at one of the facilities
more than 50% of the chlorine
partitioned to CU. the Agency
conservatively assumed in calculating
feed rate limits that 100% of the chlorine
would be partitioned to CU. Because the
CU RAC is more than an order of
magnitude lower than the HQ RAC. the
Tier I chlorine limits were based on
100% conversion of chlorine to CU. If
applicants believe that this assumption
is too conservative, they may conduct
emissions testing to document CU and
HC1 emission rates.
2. Need for CU Controls
Many commenters stated that CU
controls are unnecessary. One
conunenter believed that very little
hydrogen is needed to react with CU to
form HC1. Another conunenter believed
that operating conditions for boilers and
industrial furnaces are not conducive to
the formation of CU. Another conunenter
stated that the proposed limits to control

HC1 emissions will provide adequate
control of CI» emissions as well.
The Agency does not agree with these
commenters. As discussed above.
emissions testing indicates that a
substantial fraction of gaseous chlorine
can be emitted in the form of CIj. In
addition, the HC1 controls may not be
adequate to control Cli emissions.
Because Ct, has a much lower solubility
in water than does HC1. the use of wet
scrubbers as the principle emissions
control device for HC1 is not likely to
significantly reduce emissions of CU. CU
emissions can be controlled, however.
by increasing the hydrogen content of
feedstreams (e.g., by adding steam) or
by decreasing the feed rate of chlorine.
Moreover. EPA does not believe that
high CI> emissions relative to HC1
emissions is a widespread occurence.
3. HC1 Emission Test Procedures
A number of commenters who own or
operate cement kilns expressed concern
that EPA's HC1 stack sampling and
analysis procedure (see section 3.3 in
Methods Manual for Compliance with
the BIF Regulations) was inappropriate
because it counted as HC1 chlorine in
inorganic chloride salts and chloride
iona that are emitted as ammonium
chloride. The Agency has determined70
that the filter in the sample probe, in
fact effectively removes fine paniculate
chloride salts so that they do not
interfere with the HC1 determination.
The Agency agrees, however, with
commenters that the procedure may
consider as HC1 chloride ions that are
emitted as ammonium chloride.7'
Although the Agency has not developed
a sampling and analysis procedure that
would correct this problem, we do not
believe that any such over-reporting of
MCI will cause a cement kiln to exceed
the HCI standard. This is because the
highly alkaline particulate matter
resulting from the limestone raw
materials effectively neutralizes much of
the chlorine generated from hazardous
waste fed into the kiln.
4. Technology-Based HCI controls
Several commenters stated that
technology-based HCI emission controls
applicable to hazardous waste
incinerators (i.e.. 99% reduction of
emissions in the stack gas) should also
apply to BIFs. As discussed in the
proposed rule, the Agency continues to
believe that a 99°5 reduction standard

Kiln et Hannibal MO. December 1390. Document
No. EPA/S30-SW-91-017.
for BIFs to control HCI emissions may
be neither technically feasible nor
necessary to protect human health and
the environment. The Agency believes
that the process chemistry of some
industrial furnaces (e.g., cement kilns]
generally results in low HCI emissions
and concerns about tube corrosion
generally limit HCI concentrations in
boiler emissions. Given the low
uncontrolled HCI concentrations in
many BIFs. a 99% reduction standard in
addition to the health-based standard
required by today's final rule, may not
be cost-effective. Commenters did not
provide data or information that would
support the need for, and the cost-
effectiveness of a technology-based
standard in addition to the health-based
standard provided by the final rule.
We note that the Agency is currently
developing health effects data for two
other acid gases: hydrogen fluoride and
hydrogen bromide.
C. Implementation
Procedures for implementing the HCI
and CU controls are virtually identical to
those for the metals controls discussed
above.
1. Emissions Testing
Collection and analysis of HCI and
CU in stack gas emission samples must
be conducted according to the
procedures prescribed in section 3.3 of
the Methods Manual for Compliance
with the BIF Regulations. (Methods
Manual) incorporated in today's rule as
appendix IX of part 266. The Methods
Manual describes two procedures for
sampling emissions for HCI and CU:
Methods 0050 and 0051. Method 0050
collects a sample isokinetically and is.
therefore, particularly suited for
sampling at sources emitting acid
particulate matter (e.g.. HCI dissolved in
water droplets), such as those controlled
by wet scrubbers. Method 0051 uses a
midget impinger train sampling method
designed for sampling sources of HCI
and CU emissions not in particulate
form. Samples collected using either
method must be analyzed using Method
9057 which is also described in the
Methods Manual.
2. Wastes Analysis
Methods for sampling and analysis of
feedstreams for total chlorine and
chloride are described in detail in SW-
846.
3. Interim Status Compliance
Requirements.
As discussed in section VII of part
three of this preamble, boilers and
industrial furnaces operating under
interim status must comply with the HCI
and CU emissions standards during
interim status.
VL Nontechnical Requirement!
As proposed, the final rule requires
BIFs to comply with the nontechnical
standards applicable to other hazardous
waste treatment, storage, and disposal
facilities. These nontechnical standards
address the potential hazards from
spills, fires, explosions, and unintended
egress; require compliance with the
manifest system to complete the cradle
to grave tracking system: ensure that
hazardous wastes (and hazardous
residues) are removed from the site
upon closure; and ensure that the
owners and operators are financially
capable of complying with the
standards. BIFs burning hazardous
waste fuels that operate storage
facilities must already comply with
these standards under existing
S 266.35(c).
We also note, in particular, that
owners and operators of BIFs are
subject to the waste analysis
requirements of 11 264.13 and 265.13 by
reference. See || 286.102(a)(2)(ii) for
permitted facilities and 266.103(a)(4)(ii)
for interim status facilities. Before a
waste is stored or burned, the owner or
operator must obtain a detailed
chemical and physical analysis of a
representative sample of the waste
sufficient to enable the owner or
operator to comply with today's rule.
The nontechnical standards provided
in today's rule are identical to those that
currently apply to hazardous waste
incinerators. In today's rule.
S 266.102(a)(2) applies these standards
to permitted BIFs and 1266.103(a)(4)
applies these standards to BIFs
operating in interim status.
Finally, we note that as proposed.
today's rule applies the same controls
on fugitive emissions that currently
apply to hazardous waste incinerators.
The controls apply to facilities operating
under a permit (see I 266.102(e)(7)(i)
and. on the effective date of the rule, to
facilities operating under interim status
(see 1266.103(h)). The controls provide
for alternative control strategies
including: (1) Keeping the combustion
zone where hazardous waste is burned
(or where emissions from such burning
may migrate) totally sealed: and (2)
maintaining the combustion zone
pressure lower than atmospheric
pressure.
VTL Interim Status Standards
In addition to the nontechnical
standards discussed above, today's f^
rule requires facilities with interim
status to comply with substantive
-------

^mission controls for metals. HCl Cla
Ksrticulates. and CO (and, where
'applicable. HC and dioxins and furana).
Owners and operators must certify
compliance with the emissions controls
under a prescribed schedule, establish
limits on prescribed operating
parameters, and operate within those
limits throughout interim status.
Given that interim status requirements
are self-implementing, the Agency has
developed comprehensive interim status
requirements to ensure that the
standards are implemented effectively.
To assist the regulated community in
complying with the requirements. EPA is
developing a guidance document
entitled Interim Status Guidance
Document for BIFs (ISCO). The guidance
document will be available shortly after
publication of the final rule in the
Federal Register. The ISGD will
summarize the provisions of the rule.
provide example forms that may be used
to submit data and information required
by the certifications of precompliance
and compliance (see discussions below),
and provide guidance on developing a
compliance test protocol. To provide
further assistance to the regulated
community, EPA plans to conduct a
series of workshops open to the public
o explain how the interim status
tandards work. The workshops are
scheduled to begin shortly after
publication of the final rule in the
Federal Register. To obtain a copy of the
ISGD or information on the dates and
locations of the workshop, contact the
sources identified at the beginning of
this preamble under "FOR FURTHER
INFORMATION CONTACT".
The following sections summarize
how the interim status standards work.
.A. Certification Schedule
l. Certification of Precompiiance
The BIF rule is effective 6 months
after the date of promulgation. By the
Directive date, an owner/operator must
submit a certification of precompliance
providing prescribed information
supporting a determination that
emissions of individual metals. HCl. Cl».
and paniculates are not likely to exceed
a.iowable levels. See t 266.103(b)(2). For
certification of orecompliance. the
owner,' operator must use engineering
judgment to evaluate available
miormauon and data (cr must use EPA-
rrcscnbed default data provided in
aecticr.s 6.0 and 9.0 of Methods Manual
for Compliance with the BIF
Reculaiiar.8. incorporated in today's rule
| AS Appendix IX of part 2S6) to determine
that, under the operating limits (for EPA*
prescribed parameters) that the owner/
operator establishes, emissions are not
likely to exceed the allowable emissions
provided by §§ 286.105.266.106. and
286.107. The owner and operator must
then comply with these operating
conditions (see discussion in section
VII.B below) submitted in the
precompliance certification during the
interim status period of operation until a
revised precompliance certification is
submitted or until a certification of
compliance is submitted as discussed
below.
In addition, by the effective date of
the rule, the owner or operator must
submit a notice for publication in a
major local newspaper of general
circulation providing the general facility
information prescribed by
§ 266.103(b)(6). The information that
must be provided in the notice includes:
The name and address of the owner and
operator of the facility, the type of
facility, the type and quantity of
hazardous waste burned: the location
where the operation record of the
facility can be viewed: a notification
that a facility mailing list is being
established so that interested parties
may notify the Agency that they wish to
be placed on the mailing list to receive
future information and notices about the
facility, a brief summary of the RCRA
regulatory system for BIFs: and the
address of the EPA Regional Office
where additional information on the
RCRA regulatory system may be
obtained. EPA is requiring this public
notice to ensure that the local citizenry
is aware that the BIF la burning
hazardous waste and that to the extent
desired, the local citizenry may become
better informed about the facility
operations through site inspections and
review of data in the operating record.
In turn, this opportunity for local
involvement in facility operations
should provide an added incentive for
the owner and operator to comply with
the spirit and letter of the interim status
standards.
EPA notes that facilities that meet the
definition of "in existence" of
5 206.103(a)(l](ii) but that are not
burning hazardous waste on the
effective date of the rule must
nonetheless submit a certification of
precompliance based on planned
operations. The certification may be
revised at any time in the future if
necessary. See § 266.1Q3(b)(8).
2. Certification of Compliance
Within 13 months of promulgation, the
owner/operator must conduct
compliance testing '* and submit a
certification of compliance with the
standards for individual metals
(5 266.106). HCl and Cb (| 266.107).
particulates (i 286.105), and CO, and.
where applicable. HC and dioxins/
furana (i 266.104 (b) through (e)). The
certification of compliance is based on
emissions testing and establishes
operating limits for EPA-prescribed
parameters based on the compliance
test See ( 286.103(c)(l).
If the owner/operator cannot submit
the certification of compliance within 18
months of promulgation however, he
must either, (l) Notify the Director that
he is taking an automatic 12-month
extension under which hazardous waste
burning is limited to a total of 720 hours:
(2) obtain a case-by-case extension of
time for reasons beyond his control: or
(3) stop burning hazardous waste and
begin closure of the hazardous waste
portion of the facility. See
§ 286.103(c)(7).
The case-by-case time extension will
be provided by the Director if he
determines that the owner or operalor
has made a good faith effort to comply
with the requirements in • timely
manner but for reasons beyond his/her
control are not able to meet the
certification of compliance deadline.
Reasons could include inability to
complete modifications to an air
pollution control system in time to
conduct the compliance test to support
the certification, or a major, unplanned
outage of the facility (e.g.. need to
replace refractory in a kiln) just prior to
scheduled compliance testing, or as
discussed earlier, HC levels attributable
to organics in raw materials. The
Director may use his discretion to
determine the length of the extension.1*
The Director also may impose
conditions that ensure that the boiler or
industrial furnace will be operated in a
manner that protects human health and
the environment provided that the
Director documents the basis for adding
such a condition and provides the
applicant opportunity to comment on it.

In addition, we note that a case-by-
case extension may be requested and
granted for any interim status
certification deadline under { 266.103 (c)
or (d). A case-by-case extension may be
granted after an owner/operator has
elected to take the 12-month automatic
extension, an extension may be granted
if the owner/operator cannot comply
with the recertification schedule (see
discussion below), and an existing
extension may be extended.
3. Recertification
Owners and operators must
periodically conduct compliance testing
and recertify compliance with the
standards for individual metals. HCl and
CU participates, and CO, and. where
applicable. HC and dioxins/furans
within three years of the previous
certification while they remain in
interim status (i.e., until an operating
permit is issued under f 270.66). See
§ 266.103(d). EPA is requiring
recertifications primarily to ensure that
air pollution control systems do not
deteriorate over time.
4. Failure to Comply with the
Certification Schedule
If the owner or operator does not
comply with the certification schedule,
all hazardous waste burning must cease
as of the date of the missed deadline.
and closure must commence. See
§ 266.103(e). Any burning of hazardous
waste by such a device after failure to
comply with the certification schedule
must be under a RCRA operating permit.
See § 270.66.
To comply with the certification
schedule, complete and accurate
certifications of precompliance and
compliance must be submitted by the
applicable deadlines. (Although the
deadline for certification of compliance
may be extended (see | 266.103(c)(7)),
the deadline for certification of
precompliance may not be extended.) In
addition to terminating interim status if
the owner and operator do not comply
with the certification schedule, EPA will
also take appropriate enforcement
action.
When closing a BIF. all hazardous
waste and hazardous waste residues.
including, but not limited to, ash.
scrubber water, and scrubber sludges.
must be removed from the affected BIF.
In addition, the owner/operator must
comply with the general interim status
closure requirements of {§ 285.111-
£65.115, as amended. These
requirements, which are incorporated by
reference into today's rule, specify
closure performance standards:
submission of and compliance with a
written closure plan: disposal or
decontamination of equipment
structures, and soils: and certification
procedures for closure.
We note that under amended
§ 265.112(d)(2), for an owner or operator
who fails to submit a complete
certification of compliance by the
applicable compliance deadline
(including the automatic 12-month
extension or the case-by-case extension
under § 266.103(c)(7)(i), the date that he
"expects to begin closure" is within 30
days after the applicable deadline.
Therefore, for example, for an owner
who takes the automatic 12-month
extension, the closure notification
requirements of § 265.112(d)(l) or the
closure activity requirements of
§ 265.113 would not be triggered unless
and until the owner fails to submit a
complete certification of compliance by
the 12-month extended deadline and a
case-by-case extension beyond the 12-
month extension was not obtained.
For any other BIF owner or operator
closing during interim status operation
(i.e.. one who closes between the
effective date of the rule but before the
interim status compliance deadline of 18
months after promulgation of the rule, or
one who submits a complete
certification of compliance by the
applicable 18-month compliance
deadline, the 12-month automatic
extension, or case-by-case extension.
and closes during interim status), the
date when he "expects to begin closure"
under i 265.112(d)(2) will remain either
within 30 days after the date on which
any hazardous waste management unit
receives the known final volume of
hazardous waste, or if there is a
reasonable possibility that the unit will
receive additional hazardous waste, no
later than one year after the date on
which the unit received the most recent
volume of hazardous waste.
5. Development of the Certification
Schedule
In the 1989 supplemental notice, the
Agency requested comment on
alternative schedules for requiring
compliance with the emissions
standards during interim status. The
Agency selected a certification deadline
of 18 months (with provision for
extensions) because we believe that
most facilities will be able to install the
necessary monitoring equipment
conduct any precompliance testing that
may be necessary, and conduct
compliance testing within that time
period. Although 18 months from the
date of promulgation is a fairly short
period of time, we note that Agency
staff have made numerous public
presentations and have had numerous
discussions T4 with the regulated M
community, including, in particular. thj|
development of interim status
compliance procedures. Thus, facility
owners/operators have had some
advance indication of the general
regulatory approach taken in the final
rule.
The Agency received a comment that
the air emission standards for cement
kilns should be instituted more quickly
than the schedule proposed. The
commenter believed that accelerating
the schedule will not place an excessive
burden on these facilities because the
regulations were proposed far enough in
advance for cement kilns to come into
compliance. The Agency has considered
this comment and: (1) Sees no
compelling reason to single out cement
kilns from other BIFs for an accelerated
schedule: and (2) continues to believe
that an IB-month compliance period is
representative of the time required to
implement necessary plant design or
process modifications, install monitoring
and compliance equipment conduct
facility compliance testing, and submit a
certification of compliance testing that
documents key operating limits during
the remainder of the interim status
period. In fact the Agency is concer
that in some situations, where, for
example, the air pollution control
system may need to be modified, an 18-
month deadline may not provide enough
time to complete modifications, "shake-
down" the system, conduct pre-
testing '*, conduct compliance testing.
and analyze test data and submit a
certification of compliance. Thus, the
final rule includes provisions for time
extensions to all certification deadlines
except for certification of precompliance
under § 266.103(b).
B. Limits on Operating Parameters
Limits on operating parameters during
interim status are established at
certification of precompliance and at
certification of compliance following
emissions testing 18 months (unless
extended) after promulgation of the rule.
The operating conditions can be revised
prior to certification of compliance by
submitting a revised certification of
precompliance. The operating conditions
can be revised after certification of

compliance by conducting emissions
testing and submitting a revised
certification of compliance.
After the effective date of the rule and
prior to certification of compliance with
the emissions standards based on
emissions testing, a facility may operate
only under those conditions for which
the facility has submitted a
"precompiiance" certification
demonstrating that emissions of
individual metals, HC1. CU, and
participates are not likely to exceed
allowable levels. The operating
conditions for which limits are
established by precompiiance are (see
§ 266.103(b)(3)):
• Feed rate of each of the 10 metals
in:
—Total feed streams, except for
furnaces that recycle collected
particulate matter (see discussion in
section VI1.I below)
—Total hazardous waste feed streams
—Total pumpable hazardous waste feed
streams:
• Total feed rate of chlorine and
chloride in all feed streams:
• Total feed rate of ash in all feed
streams, except for cement and light-
weight aggregate facilities for which ash
content of feed streams is not an
operating parameter
• Total feed rate of hazardous waste
and feed rate of pumpable hazardous
waste; and
• Maximum capacity in appropriate
units such as heat input steam
production, or raw material feed rate.
In addition, the following parameters
must be considered in demonstrating
precompiiance and must be
continuously monitored (and records
maintained in the operating log) when
monitoring systems are installed (see
§ 266.103(b)(6)):
• Maximum combustion zone
temperature:
• Maximum flue gas temperature
entering the PM APCS: and
• Limits for APCS-specific operating
parameters.
Once a facility has conducted
compliance testing and certified
compliance with the emissions
standards, limits for all of the above
parameters, as well as for CO (and.
where applicable. HC) are established
based on the compliance test and
remain in force until recertification
under new conditions. See
S 266.103(c)(l).
C. Automatic Waste Feed Cutoff
Upon certification of compliance, an
automatic hazardous waste feed cutoff
system must engage when the limits
(established in the certification) for the
following operating parameters are
exceeded (see { 266.103(g)):
• Total feed rate of hazardous waste
and feed rate of pumpable hazardous
waste;
• Limits on CO and, where
applicable. HC
• Maximum production rate in
appropriate units such as heat input
steam production, or raw material feed
rate:
• Maximum combustion zone
temperature;
• Maximum flue gas temperature
entering the PM APCS: and
• Limits for APCS-specific operating
parameters.
Facilities operating during interim
status after certification of compliance
must test the automatic waste feed
shutoff system once every 7 days to
ensure that it is operating properly,
unless an owner/operator can document
that weekly testing will result in unsafe
conditions. See S 266.103(j)(3). In all
cases, testing at least every 30 days is
required. Owners/operators are
required to document the results of
these tests and all automatic waste feed
shutoffs that occur during normal
operations.
D. Sham Recycling Policy
The BIF rules supersede the Agency's
sham recycling policy (see 48 FR11157
(March 16.1983)) after the owner or
operator certifies during interim status
compliance with the emissions
standards for metals. HCL CU.
participates, and CO (and. where
applicable, HC and dioxins and furans).
Thus, after certification of compliance, a
BIF may bum hazardous waste (other
than waste fed solely as an ingredient or
solely for material recovery) with a
heating value lower than the 5.000 Btu/
Ib limit generally considered heretofore
to be the minimum for a legitimate
hazardous waste fuel. Although the
Agency considers such burning to be
treatment we believe that confonnance
with the emissions standards upon
certification of compliance under
S 266.103(c) will ensure protection of
human health and the environment
(Prior to today's rule, BIFs burning a
hazardous waste that was not
considered to be a legitimate fuel were
subject to the subpart O incinerator
standards of parts 264 and 265.
assuming burning was not for some
other legitimate recycling purpose, such
as material recovery.)
Although we indicated above that a
BIF may bum hazardous waste for the
purpose of treatment upon certification
of compliance, today's rule allows BIFs
to bum such hazardous waste for a total
period of time not to exceed 720 hours
prior to certification of compliance. See
S 266.103(a)(6). The rule allows such
burning only for purposes of compliance
testing (and pretesting to prepare for
compliance testing) to determine that
the device can comply with the
emissions standards while burning
waste for treatment. The rule limits such
burning to a total of 720 hours because
we believe that period of time is
adequate to complete any pretesting and
compliance testing, and it is the same
period of time that new BIFs may burn
hazardous waste during the pretrial
burn period under S 270.66(b)(l).
The Agency discussed three options in
the 1989 supplemental notice for
superseding the sham recycling policy:
Rescinding the sham recycling policy on
the effective date of the final rule;
rescinding the sham recycling policy
when a facility comes into compliance
with the interim status emission
standards; or leaving the sham recycling
policy in effect until a RCRA operating
permit is issued.
The Agency received comments.
supporting all three of the options. Eight
commenters supported the first option.
rescinding the sham recycling policy on
the effective date of the final rule,
because the policy is considered
guidance. Eight commenters supported
the second option, rescinding the sham
policy when facilities come into
compliance with the interim status
emission standards, because the
standards are protective of human
health and the environment. Five
commenters supported the third option.
leaving the sham recycling policy in
effect until a facility is issued a RCRA
operating permit because the permit
writer oversight during the permit
process is necessary to ensure that a •
facility complies with the appropriate
regulations.
The Agency believes that the
procedures required for certification of
the interim status emissions standards
are adequate to ensure effective
implementation and enforcement of the
standards. The only emissions standard
applicable to permitted facilities that is
not required during interim status is the
destruction and removal efficiency
(ORE) standard requiring a trial bum to
demonstrate 99.99% ORE. The Agency
does not believe that this is necessary
because emissions testing of boilers and
industrial furnaces indicates that
facilities with CO and HC levels within
the limits established by today's rule
also are likely to achieve 99.99% ORE.
It should be noted that in rescinding
the sham recycling policy for these types
of regulated boilers and industrial
furnaces, the Agency is not altering in
-------
TIM FsdenJ Register / Vol 56. No. 35 / Thursday, February 21 IflM / Rules and Repdati
any way what secondary materials are
defined as solid and hazardous wastes
when burned for legi&mate energy
recovery. Thus, all spent materials,
sludges, and by-products are solid
wastes when burned for recovery, as are
off-specification commerical ^harniml
products which are burned as fuels (or
used as a component of fuels) in lieu of
their original intended use. See
S1281.2(c)(2) and 261.33. (Non-listed
hazardous commercial chemical
products (La, those that exhibit a
characteristic but are not listed in
I 261.33) are likewise solid wastes when
they are recycled in ways that differ
from their normal use. SO FR at 14219
(April It 1985).) With respect to the
issue of what constitutes a normal
manner of use for an off-specification
commercial chemical product that h"«
some Btu value, or the issue of when
such a material is used "in lieu of {its]
original intended use" (S 261.33) and so
is a solid and hazardous waste, the
Agency notes that not every type of
burning ostensibly for energy recovery
is considered to qualify. Inappropriate
modes of burning thus do not render
such materials non-wastes. For example,
if ignitable off-specification natural gas
condensate is burned as a motor fuel or
reactive jet fuel (U133, hydrazme) is
burned as conventional fuel oil, such
materials are solid and hazardous
wastes and subject to subtitle C
controls. This is because the mode of
burning is not at all like these materials'
original intended use.
E Submiitai of Part B Applications
Permit writers wifl require owners and
operators to submit part B applications
for operating permits on a schedule
considering the relative hazard to
human health and environment the
facility poses omapared to other storage,
treatment and disposal facilities within
the Director's purview.
F. ORE Testing
As proposed, testing to demonstrate
99.90% destruction and removal
efficiency (ORE) of organic compounds
in die waste is not required under
interim status. The complexity and costs
of ORE testing, as well aa the
substantial interaction needed between
owners/operators and regulatory
officials, make such testing
impracticable during interim status. EPA
expects that the control requirements for
CO and HC will result in low levels of
emissions of organic compounds.
G. Chlorinated Dioxint and Parana
As proposed, hazardous, waste
containing or derived from any of the
following dienan lasted wastes cannot be-
burned in a boiler or industrial furnace
operating under interim status: EPA
Hazardous Waste Nos. FOzQ. F02L FQ22,
F023, F02B. and F027. Burning these
dioxin-containing wastes during interim
status is prohibited because boilers and
industrial furnaces cannot be assumed
to achieve the 99.9999 percent ORE
required for these wastes.
Even though these wastes may not be
burned during interim status,
chlorinated dioxins and furans may be
emitted as PICs under certain conditions
(i.e.. when the PM control device is
operated within the temperature range
of 450-750'F. or when HC
concentrations exceed 20 ppmv) as
discussed in section ILE of part three of
the preamble. EPA believes that the
emissions testing and risk assessment
requirements of | 266.104(e) can be
effectively implemented during interim
status without significant EPA
interaction. Thus, the rule requires, the
owner or operator to certify compliance
with those requirements, as applicable.
H. Special Requirement* for Aunoce*
Today's rule provides special interim
status requirements for industrial
fumances that feed hazardous waste,
except hazardous waste fed soferjr as an
ingredient** at locations other than the
"hot" end when the product is
discharged and fuels an normally find
to ensure adequate combustion of
hazardous waste prior to conducting a
trial burn during the part B permit
process (see f 266.103(aH5)) as foQows:

(2) the owner or operator must
determine (and include such
determination in the operating record)
that there is sufficient oxygen present to
combust the waste: (3) the continuous
hydrocarbon monitoring control*
provided by i 266.104(d) apply: and (4)
for cement Irilna, hazardous waste must
be fed into the kirn itself;
EPA established a minimum
temperature of 1600 *F for the location of
hazardous waste firing and is requiring
that the owner/operator demonstrate
that adequate oxygen is present to
sustain combustion given that it is
generally accepted that organic
compounds are readily destroyed at
temperatures above 1800 *F hi the.
presence of adequate oxygen. The
demonstration of adequate oxygen is
particularly important for cement fains
because they are operated dose to
stoichiometric oxygen levels (i.e.. with
little excess oxygen in the Itiht) to
efficiently maintain the Kigh
temperatures necessary to calcine and
sinter the raw materials. Although -
higher excess oxygen levek would
better ensure more complete combustion
of fuels, operating at higher oxygen
levels is less thermally efficient and
reduces the kiln production capacity.
In addition, continuous hydrocarbon^
(HC) monitoring is required to •
demonstrate that HC levels do not "
exceed the regulatory limit of 20 ppmv
on a hearty roiling average basis (or
alternative level established andar
i 28&104(f)) irrespective of whether the
CO level is less than 100 ppmv where
HC monitoring is not normally required.
See I 266.103(a)(5). EPA is requiring HC
monitoring because of the concern that
CO monitormg alone may not be an
adequate indicator of good combsBtion
conditions when hazardous waste is fed
at locations other than where
(nonhazardous) fuels are normally find.
See discussion in part three, section
HB.4.a of this preamble. Continuous
monitoring of HC and compliance wim
the applicable operating limit is required
upon certification of compliance (or. for
fumances that feed raw materials
containing organic matter and that
receive a time extension to certify
compliance, upon receipt of the time
extension."
The Agency considered whether the
hydrocarbon controls were redundant to
the operating requirements specified
above and concluded that HC
monitoring is needed to effectively

Federal Register / Vol. SO. No. 35 / Thursday. February 21. 1991 / Rules and Regulation* 7185
plement and enforce the controls on
tic emissions. Although the
Derating requirements alone should be
adequate to limit organic emissions,
absent HC monitoring there would be no
continuous verification that the
operating requirements were, in fact,
adequate and that the owner/operator
maintained compliance with the
operating requirements.
Finally, the rule requires that
hazardous waste be fired into a cement
kiln itself to ensure that the waste is not
introduced at a location that may not be
conducive to complete combustion of
the waste. For example, cement
companies have considered burning
hazardous waste in the precalciner of a
cement kiln. Although such practices
may prove during the permit process to
be acceptable. EPA has not tested
emissions from a kiln burning waste at
locations other than in the kiln itself,
and is concerned that complete
combustion of organic constituents may
not be ensured Thus, burning hazardous
waste in a cement kilns precalciner is
not allowed during interim status. (This
restriction is limited to cement kilns
because this is the only type of kiln of
which the Agency is aware where
hazardous waste may be fired at a
ocation that is clearly not designed for
Yimum combustion conditions. A
_ nent kiln precalciner is designed
primarily to achieve calcining of raw
materials and may not provide adequate
combustion of hazardous waste.)
The special requirements do not apply
to hazardous waste that is burned
(processed) solely as an ingredientT*
because such waste does not contain
significant levels of hazardous nonmetal
constituents (i.e., compounds listed in
appendix VIII. part 261) and. thus.
nonmetal emissions will not pose
significant risk to human health and the
environment. (Metal emissions will be
adequately controlled by today's rule
irrespective if where the waste is fed
into the system because metals are
controlled by a PM control device.)
Thus, emissions of nonmetal compounds
are not of concern when a waste is
burned (processed) solely as an
ingredient. EPA considers a waste to be
burned solely as an ingredient in a kiln
if it is not burned partially as a fuel.or

for conventional treatment (i.e.,

waste that is fed to boilers and
industrial furnaces to be burned at least
partially for energy recovery and not as
an ingredient if it has a heating value of
5,000 Btu/lb or greater, as-generated.
and at least partially for treatment (i.e..
destruction) if it contains more than a
total of 500 ppm (by weight) of appendix
VUI. part 261, nonmetal hazardous
constituents. See 54 FR at 43731-32
where EPA discussed use of a 500 ppm
standard for distinguishing between
recycling activities tantamount to
production and those constituting
conventional treatment
The Agency notes in addition that it
ordinarily does not consider metal-
bearing wastes hazardous wastes to be
used as ingredients when they are
placed in industrial furnaces
purportedly to contribute to producing a
product (The use of metal-bearing
wastes for material recovery is
discussed earlier in the preamble, and
this discussion does not deal with the
issue of when such wastes are burned
for legitimate material recovery in
industrial furnaces.) To be considered
legitimate use as an ingredient it would
normally need to be demonstrated to
EPA (or an authorized State) pursuant to
§ 261.2(f) that the hazardous metal
constituents in the waste ara necessary
for the product (i.e.. ara contributing to
product quality) and are not present in
amounts in excess of those necessary to
contribute to product quality. See 50 FR
at 638 (Ian. 4.1985). This would
normally require some demonstration
that these hazardous metal constituents
do not render the product unsafe for its
intended use. (The other sham recycling
criteria discussed frequently by EPA
would also have to be satisfied. See.
e.g.. 53 FR at 522 (Jan. 8.1988).) The
types of uses of hazardous wastes in
industrial furnaces to produce waste-
derived products of which the Agency is
aware, such as using hazardous wastes
to produce aggregate or cement (the
Agency is not actually aware of cement
kilns using hazardous wastes ostensibly
as ingredients, although some facilities
have contemplated engaging in the
practice) do not appear to satisfy these
criteria. In addition, the Agency notes
the discussion earlier in this preamble
(in the context of hazardous waste used
as slurry water) to the effect that the
more common and less valuable the raw
material the hazardous waste is
replacing, the mora likely the activity is
to be some form of surrogate treatment
/. Special Metals Controls for Furnaces
that Recycle Collected Particulate
Matter
For reasons discussed in section
IV.C.4 of this preamble, the final rule
requires owners and operators of
furnaces (e.g., cement kilns, light-weight
aggregate kilns with dry paniculate
matter (PM) control systems) that
recycle collected PM back into the
furnace to implement the metals
emissions controls of i 266.106 (c) or (d)
under one of the three alternative
methods. The discussion in section
IV.C.4 of the preamble summarizes
procedures for certification of
compliance under the methods. For
certification of precompliance, the
standard procedures will be used for
both the "daily emissions testing"
option, and the "conditioning prior to
compliance testing" option.
Precompliance procedures are different
however, for the "monitoring metals in
collected PM" method, as discussed
below.
Under the "monitoring metals hi
collected PM" method, operating limits
will be established for all of the
parameters listed in section VDLB. above
except for the feed rate limit on each
metal in total feedstraams. In lieu of that
parameter, the special procedures limit
the concentration of each metal in
collected PM. See "Alternative
Methodology for Implementing Metals
Controls" in Methods Manual for
Compliance with the BIF Regulations
(incorporated in today's rule as
appendix IX of part 266).
For certification of precompliance, the
owner/operator must estimate the
enrichment factor for each metal using
engineering judgment or EPA prescribed
default values. EPA default values are
100 for mercury and 10 for all other
metals. The enrichment factors are then
used to calculate precompliance dust
metal concentration limits using the
allowable emission rate for each metal
and the applicable PM standard using
the same procedures applicable for
certification of compliance. Daily (or
weekly for noncritical metals) analysis
of dust samples is required. If more than
3 of the previous 60 samples fail, the
owner/operator must notify the
Director. The owner/operator is then
allowed to bum hazardous waste for up
to 720 hours before a revised
certification of precompliance must be
submitted that revises the estimated
enrichment factors and establishes
revised precompliance dust metals
concentration limits. The revised
enrichment factors must be based on
testing or engineering judgment using

data or information not considered in
the original estimate.
/. Recordkeeping
Over the period of interim status,
facilities will be required to generate
and maintain data and records designed
to demonstrate routine compliance with
established limits on operating
parameters. These records must be
sufficient to allow a RCRA inspector to
review and evaluate recent and past
operation of the facility for compliance
purposes. Records must be maintained
for a period of three yean or until an
operating permit is issued under
§ 270.68. whichever is later.
Vin. Implementation of Today's Rule
There are three types of treatment
storage, and disposal facilities (TSDFs)
which may be affected by today's rale:
(1) Facilities which are subject to RCRA
permit requirements for the first time as
a result of today's rule; (2) facilities
which are already operatiag wider
interim status; and (3) facilities that
have been issued a RCRA permit The
following sections describe the
compliance obligations for facilities that
have units subject to permitting due to
today's rule.
A. Newly Regulated Facilities
Prior to receiving a permit newly
regulated facilities (La* facilities which
only contain the types of units newly
regulated by today's final rule) must
qualify for interim status by the effective
date of the rule in order to continue
managing hazardous wastes in units
newly regulated by today's rule. To
obtain interim status, the eligible facility
must meet three criteria: {!) On the
effective date of the BIF rule, the facility
moat be "in existence" with respect to
hazardous waste burning or processing
activities; (2) within 90 days of the date
of publication, the owner or operator
must notify EPA or an authorized State
(if not previously required to do so) of
the facility's hazardous waste burning or
processing activities: and (3) within 180
days of the date of publication, the
owner or operator must submit part A of
the permit application.
1. Definition of "In Existence".
To meet the definition of an existing
facility, die boiler or industrial furnace
must either be in operation burning or
processing hazardous waste on or
before the effective date of the rule, or
construction of the facility (including the
hazardous waste burning or processing
equipment) must have commenced on or
before the effective date of the rule. See
1266.103

Federal Register / Vol. 56, No. 35 / Thunday, February 21, 1991 / Rules and Regulations 7187
November 8.1988). See RCRA section
300S(c)(2).
EPA amended iti regulations on July
IS, 1985 to incorporate these and other
HSWA changes. See 50 FR at 28703.
EPA's intention in promulgating these
amendments was simply to reflect the
new statutory provisions; for the most
part the Agency simply codified into the
regulations the new HSWA language. Id.
at 28703. In light of the largely
ministerial nature of the regulations, and
in view of the need to move quickly to
incorporate HSWA. EPA published
these 1985 regulations without
opportunity for public comment Id. (The
D.C. Circuit eventually sustained the
legality of these procedures in United
Technologies Corp. v. EPA, 821 F.2d at
714 (D.C. Cir. 1987).)
Section 270.73 (f), (g) sets forth the
dates on which interim status for
incinerators and other non-land disposal
facilities terminates if the facilities fail
to submit their part B applications.
However, in contrast to the HSWA
amendments, the sections by their term*
apply to all incinerator and other non-
land disposal facilities, instead of being
limited only to those facilities which had
obtained interim status on November 8,
1984. the date of the HSWA
amendments. In fact it is impossible for
units newly subject to regulation after
the specified dates for submission of
part B permit applications (such as the
boilers and furnaces regulated by
today's rule, or certain facilities newly
subject to regulation under the recent
Toxicity Characteristic rule) to comply
with the rules as codified. EPA did not
intend for these rules to deviate from
statutory language. As the preamble to
the 1985 codification regulations stated.
the Agency simply intended for section
270.73 (f). (g) to reflect the HSWA
termination-of-interim status provisions.
Id. at 28723.
The Agency is today making a
technical correction to these sections to
correct this mistake, and to avoid the
unintended (and possibly illegal) result
that large classes of newly regulated
units are ineligible for interim status
because they failed to submit part B
applications at a time they were
unregulated. EPA is proceeding without
proposing the correction for public
comment and believes that public
comment is unnecessary, for the
following reasons: (1) This correction
simply conforms the language of the
regulations to the Agency's original
expressed intent in promulgating the
1985 regulations, which themselves were
validly promulgated without the
opportunity for comment (2) this
correction simply conforms the
regulations to HSWA's plain language;
(3) the amendment conforms the
regulations to the Agency's actual
practice in implementing the regulations
and RCRA 3005(c)(2); (4) the amendment
is necessary to avoid rendering units
newly regulated after specified part B
permit application submittal dates from
being ineligible for interim status even
though they meet ail of the statutory
interim status eligibility criteria; and (5)
the amendment can be viewed as an
interpetative rule, which does not
require prior notice and public comment
C. Permitted Facilitiet
Some permitted facilities contain
boiler and furnace units that are newly
subject to subtitle C regulation as a
result of today's rule. These permitted
facilities must therefore submit permit
modifications to EPA Regional offices,
and comply with federal permit
modification procedures in order to
continue to manage hazardous waste in
these units. The modification will be
processed under Federal permit
modification procedures rather than
authorized state procedures because
this rule is promulgated under HSWA
authority.*0 However, because the
permit undergoing modification is most
likely a jointly issued EPA-state RCRA
permit a copy of the modification
request should also be submitted to the
state if it is an authorized state.
1. Amendment to 1270.42(g)
Today's rule contains a new permit
modification procedure in 1270.42 for
the addition of any newly regulated
waste management units used to
manage hazardous wastes (SM
{ 270.42(g)). This two-step procedure
essentially allows the permittee to notify
the Agency of its newly regulated
boilers and furnaces using the Class 1
permit modification procedures, and to
continue to handle hazardous wastes.
Subsequently, the permittee must submit
a Class 2 or 3 permit modification
request to initiate a permanent change
to the permit The self-implementing
interim status standards of 1286.103
would apply until the permit waa
modified using the Class 2 or 3
modification procedures. This new
permit modification provision only
applies to newly regulated units that
were not previously subject to the
permitting requirements of subtitle C of
RCRA.
Today's new permit modification
provision for newly regulated units is
•• Bxo»pt bowavar. tht proviafcMa far (Me*
dtyan, canoQ fayatMFatioQ mitt, tanvno
IndMMton. and plaama tie tndnaratara an not

essentially identical to the special
procedure in 1270.42(g) for newly
regulated wastes. The purpose of
today's amendment is to extend the
same opportunities and procedures that
are available for newly regulated waste
streams (and any units used to manage
them) to those situations where the unit
becomes newly regulated in absence of
a new waste identification. (See 53 FR
37922, September 28,1988.) EPA believes
that the same rationale applies to newly
regulated types of units, and is therefore
clarifying this provision hi today's rule.
Without the procedure in 9 270.42(g),
the facility would need to obtain an
approved permit modification if the
facility were to continue managing
hazardous wastes past the effective date
of today's rule, which establishes
management standards for boilers and
industrial furnaces. If the modifications
wen not approved within six months.
these facilities would be barred from
handling hazardous wastes, disrupting
the ongoing operations of many of these
facilities as well as other RCRA
facilities that would then need to
manage the wastes. As discussed below.
EPA believes that the addition of •
boiler or industrial furnace to a facility's
permit is a Class 3 modification.
Because of the time allowed for
preparation of the modification request
by the facility and public participation
in the permit modification procedures,
the Agency would be unable to review
and make a final determination on the
modification request in the six month
period.
Today's technical correction rectifies
a potential inequity between permitted
facilities and newly regulated facilities.
Newly regulated facilities are required
only to submit part A of the permit
application, and submit the RCRA
section 3010 Notification form, if
necessary, to obtain interim status. Both
activities can be easily completed by the
effective date of today's rule, allowing
them to continue operations, while
permitted facilities, who have undergone
the scrutiny of the permitting process,
would likely be barred from doing so.
2. Procedures to Modify Permits
Under today's new procedures in
{ 270.42(g). a unit that is "in existence"
as a unit by managing hazardous waste
on or before the effective date of today's
rule must submit a Class I modification
by that date. Essentially, this
modification is a notification to the
Agency that the facility is managing
hazardous wastes in these newly
regulated units. It could consist of a
revised part A application form-clearly
indicating all activities that are newly
-------
7138 Federal Register / VoL 56. No. 35 / Thursday, February 21, 1991 / Rules and Regulations
regulated as a result of today's rule. As
part of the Class 1 procedure, the
permittee must also notify the public
regarding the modification within 90
days of submittal to the Agency.
Next, within 180 days of the effective
date, the permittee must submit a Class
2 or 3 modification request to the
Agency. It is at this time that the
detailed part B information must be
submitted. The Agency believes that the
Class 3 permit modification procedures
are mostly likely applicable to the
addition of boilers or industrial furnace
units. The Class 3 modification requires
an initial public notice by the facility
owner of the modification request, a 60
day public comment period, and an
informal meeting between the owner
and the public within the 60 day period
After the end of the 60 day public
comment period, the Agency will
develop a draft permit modification.
open a second public comment period of
45 days and hold a public hearing. After
the public comment period, the Agency
will make a final decision on the
modification request
Today's rule also amends appendix I
to { 270.42 to classify the permit
modifications for boilers and industrial
furnaces. Section L is revised to include
boilers and industrial furnaces with
incinerators, and to specify additional
permit conditions to conform with
today's rule (and the conditions added
to incinerator permits under the
omnibus authority of 1270.32(b)(2). For
more information on these permit
modification procedures, see S3 FR
37912, September 2& 198&
D. Addition of Storage Units as Direct
Transfer Facilities That Obtain Interim
Status
As discussed in section XILC of part
Three of this preamble, the requirements
for boilers and industrial furnaces an
being promulgated under section 3004(q)
of RCRA, which is a HSWA provision.
As a result under section 3008(g). EPA
will implement these requirement* in
both authorized and unauthorized States
until the State is authorized to
implement these requirements in lieu of
EPA. Based on comments received
during the rulemaking. EPA is aware
that many interim status facilities
newly-regulated under this rule may
wish to add storage units to their
facilities in the future rather than.
continue direct transfer operations
(direct firing of the burner from the
transport vehicle). Furthermore. EPA
recommends that facilities install tanks
and reduce or eliminate direct transfer
practices because of the additional
hazards associated with the practice. As
discussed in more detail below, EPA
believes that such units can be added to
the facility without awaiting complete
permitting.
1. Unauthorized States
Facilities that wish to shift to storage
from direct transfer operations and that
are located in unauthorized states, will
generally be able to add such units to
the facility as a change in interim status
under 40 CFR 270.72(a)(3). In order to
qualify for addition of units under this
provision, the facility must: (1) Obtain
interim status for the boiler or industrial
furnace; and (2) submit a revised part A
application to the EPA Regional Office
prior to adding the storage units with a
justification for the change. Because
EPA strongly encourages the
discontinuation of direct transfer
operations at boilers and industrial
furnaces, EPA believes that the addition
of storage units at such facilities
constitutes a change necessary to meet
federal requirements under 40 CFR
270.72(a)(3)(u). The Regional Office must
approve the interim status change,
unless it is covered by amended
S 270.72(a)(6) just discussed. Although
40 CFR 270.72(b) limits the extent of an
addition that can be made during
interim status, the addition of associated
storage units under today's rule would
be exempt from this limitation pursuant
to $ 270.72(b)(2).
2. Authorized States
Interim status facilities located in
authorized states that wish to
discontinue direct transfer operations
will also generally be able to add such
units to the facility pursuant to 40 CFR
270.72(a)(3). In states which are not
authorized to implement the HSWA
storage requirements for boilers and
industrial furnaces, the procedure for
adding storage units at new interim
status boilers or industrial furnaces is
the same as described above for
facilities located in unauthorized states.
Because EPA is implementing both the
rule promulgated today and the
associated storage requirements in such
states, the federal rules governing
changes in interim status apply to both
the boilers and industrial furnaces and
the addition of associated storage
facilities.
In states which have been authorized
to implement the HSWA storage
requirements for boilers and industrial
furnaces, facilities newly regulated
under today's rule must comply with the
authorized state requirements
concerning the addition of associated
storage units. In some cases, the
authorized state may require the facility
to obtain a permit prior to constructing
or operating such storage units.
E. Compliance with BIF Versus
Incinerator Rules
Existing rules (see i 266.31(c)) require
that cement kilns burning hazardous
waste that are located in urban areas
must comply with the hazardous waste
incinerator standards. In addition,
existing rules allow owners/Operators
of any boiler or industrial furnace to
obtain an incinerator permit These
provisions exist because the Agency had
not yet established regulatory controls
for BEFi. In fact the statutory provision
(section 3004(q)(2)(c)) requiring that
cement kilns in urban areas be regulated
as incinerators states that the "* * *
regulations remain in effect until the
Agency develops substantive standards
for cement kilns burning hazardous
waste." Therefore, on the effective date
of the BIF rule, both of these regulatory
provisions will be rescinded except as
discussed below.
Commenters questioned what
regulations should more appropriately
apply under three scenarios: (1) If a BIF
is operating in interim status under the
subpart O, part 265, incinerator
standards; (2) if a BIF has already been
issued an incinerator operating permit
under subpart O. Part 264; and (3) if a A
BIF has previously submitted a part B •
application for an incinerator permit ancr
the permit review process has
progressed substantially by the effective
date of the BIF rule. A BIF currently
operating under the interim status
incinerator regulations must comply
with the BIF regulations on their
effective date in lieu of the incinerator
regulations so that it is subject to the
more stringent BIF rule. A BIF currently
operating under an incinerator permit
will continue under that permit until it is
reviewed or the permit term otherwise
expires. At that time, the BIF rule will
apply. Although the Agency's general
policy is that BIFs are to be regulated
only under the BIF rules, we believe
permit officials should use their
discretion to determine whether to grant
exceptions for the third situation given
the protectiveness of the standard*, and
the desirability of avoiding further delay
and expense by having to duplicate the
permit process under these BIF rules.
For example, if a BIF is operating under
the incinerator interim status standard*
but has submitted part B of the
incinerator permit and the permit
proceedings have progressed
substantially, the Director may continue
processing the permit (and issue it) ™
under the incinerator standards and use

omnibus authority il to add conditions
to the permit as necessary to conform
with the BIF rule.
DC. Permit Procedures
A. Part B Information
As proposed on May 6,1987 (52 FR
17015), S 270.22 provides specific
information requirements for part B of
the permit application. Paragraph (a)
requires a trial bum to demonstrate
conformance with the performance
standards of S S 266.104 through 266.107.
except where the trial bum is waived.
Although the regulatory language is
substantively the same as proposed, it
has been restructured for clarity, by
specifying the documentation required
to support a waiver from each type of
trial bum: ORE trial burn, paniculate
matter trial burn, metals trial bum. and
HQ/Cb trial bum.
In addition, the rule specifics under
S 270.22(a)(6) that owners and operators
may submit data from previous
compliance testing of the device, or from
testing of similar boilers or industrial
furnaces burning similar wastes, in lieu
of a trial bum provided that the data is
determined adequate and sufficient
documentation of similarity is provided.
Paragraph* (b) through (e) were added
to 1270.22 to provide information
requirements related to other regulatory
provisions being promulgated today for
boilers and industrial furnaces.
Paragraph (d) requires information
describing the automatic waste feed
cutoff system. Paragraph (e) requires
owners and operators using direct
transfer operations to feed hazardous
waste from transport vehicles directly to
the boiler or industrial furnace to submit
information supporting conformance
with the direct transfer standards at
S 266.111. Under paragraph (e), owners
and operators that claim their residues
are excluded from regulation under
§ 266.112 must submit information
adequate to demonstrate conformance
with those provisions.
B. Special Forms of Permits
As proposed, the final rule adds
S 270.66 to subpart F of part 270. This
section establishes special forms of
permits (see discussion below) for new
boilers and new industrial furnaces, and

sets forth requirements for the various

depending on applicable trial burn
requirements. This section also
establishes trial burn procedures.
Finally, this section discusses special
procedures for permitting existing
facilities. Although these provisions
were described in the preamble to the
proposal, at 52 FR 17016, they are
described briefly below, in order to
highlight minor changes from the
proposed requirements.
1. Permits for New Boilers and Industrial
Furnances.
Paragraph (b) specifies four operating
periods of a permit for a new facility.
The provisions have been restructured
from those proposed in recognition of
the fact that all boilers and industrial
furnaces subject to a permit must
undergo some type of trial burn.
Although a facility could conceivably
meet the requirements for a waiver of
the DRE trial burn, participate matter
trial burn, metals trial bum, and HCl/Qa
trial bum. all regulated facilities must
demonstrate conformance with the
carbon monoxide, and where applicable.
hydrocarbon limits or 5 266.104.
In addition, minor revisions to this
section have been made to make the
permit process for new boilers and
industrial furnaces consistent with the
way the hazardous waste incinerator
permitting process is implemented, to*
one permit with four periods of
operations rather than an individual
permit for each period of operation.
Thus, the final rule provides for
permits addressing four periods of
operation for all boilers and furnaces:
The pre-trial burn period, the trial bum
period, the post-trial bum period, and
the final permit period.
Conditions addressing compliance
with each performance standard (or
corresponding waiver requirement) will
be set in the permit for each period of
operation. Applicants must submit a
statement with part B of the permit
application that suggests the condition*
necessary to operate in conformance
with the performance standards of
S 5266.104 through 266.107. For those
performance standards for which a trial
bum is required, the Director will use
his engineering judgment and
consideration of the applicant's
proposal, in setting operating condition*
in the permit sufficient to meet the
performance standards. Once the trial
bum data are available, they will be
used to modify, if necessary, the final
operating conditions in the permit For
those performance standards for which
a trial burn demonstration is not
required (for example, when the
applicant has chosen to comply with
Tier I of the metals limitations under
{ 266.106(b)), appropriate conditions (in
the above example, metals feed rate
limits specified under § 266.102(e)(4))
will be set for all periods of operation.
The pre-trial bum period begins with
initial introduction of hazardous waste
into the boiler or industrial furnace and
extends for the minimum time required,
not to exceed 720 hours of hazardous
waste burning, to bring the device to a
point of operational readiness to
conduct a trial burn. This period may be
extended once by the Director if good
cause is shown. The trial bum period
covers the period when the trial bum is
conducted. This period is followed by
the post-trial bum period, which extends
for the minimum time necessary to allow
analysis, data computation, and
submission of the Mai bum results and
modification of the permit by the
Director if necessary to reflect the trial
bum results. Such modifications will
proceed under the permit modification
provisions at § 270.42.
Paragraph (c) specifies information
that must be included in the trial burn
plan. Paragraph (d) establishes trial
bum procedures, including criteria for
approval of trial bum plans and
requirements for submission of trial
bum data. Paragraph (e) establishes
procedures for selection of POHCs when
a DRE trial bum is required. Finally,
paragaph (f) establishes the
determinations that the applicant must
make based on the trail bum results—
the data, analyses, and computations
that must be submitted to support
conformance with the applicable
emissions standards.
2. Permit Procedures for Interim Status
Facilities.
Applicants owning or operating
existing boilers or industrial furnaces
will be permitted under i 270.66(g). This
paragraph addresses submission of trial
bum plans and trial bum data for
existing boilers and furnaces. These
provisions differ from the proposal in
that they specifically require that the
applicable trial burn data be submitted
and considered prior to permit issuance.
This language conforms with the
January 30,1989 change to the
hazardous waste incinerator regulations
promulgated at 54 FR 4288 providing
clarification of this point.
X. Exemption of Small Quantity Burner
Section 3004(q)(2)(B) of RCRA
provides EPA with explicit authority to
exempt from regulation facilities that
burn small quantities of hazardous
-------
7190 Federal Register / Vol 56. No. 35 / Thursday, February 21. 1991 / Rules and Regulations
wastes if the wastes are burned at the
same facility at which they are
generated. The Administrator is to
ensure that such waste fuels are burned
in devices designed and operated in a
manner sufficient to ensure adequate
destruction and removal to protect
human health and the environment
The Agency has carefully evaluated
the risks posed by small quantity
burning snd concluded that a
conditional exemption for small quantity
turners should be allowed where
hazardous waste combustion poses
insignificant risk. A discussion of the
original May 1987 proposal and the
subsequent October 1989 proposed
revisions is presented below.
On May 6.1987 (52 FR 17034). the
Aaency proposed to exempt facilities
that burn small quantities of hazardous
wjsie that they generate on site because
even in the absence of regulatory
control, the health risk posed by such
burning would not be significant
Eligibility for the exemption would have
been base on the quantity of waste
burned per month, established as a
function of device type and thermal
capacity. In order to be exempt in
addition to restricting the quantity of
waste burned, a facility was required to
notify the Regional Administrator that it
is a small quantity burner. Limit the
maximum instantaneous waste firing
rate to 1% of total fuel burned, and
refrain from burning acutely toxic waste
containing dioxin.
On October 26.1989 (54 FR 43730), the
Agency proposed several revisions to
the exemption in the 1987 notice. Rather
than establish hazardous waste quantity
limits as a function of device type and
capacity, EPA proposed quantity limits
that vary as a function of effective stack
height The exempt quantities proposed
in October 1989. and promulgated today.
include several changes to the risk
assessment methodology. In particular.
the quantities are based on evaluation
of risks from hydrocarbon (HC)
emissions instead of a PIC/POHC ratio
as originally proposed. This change was
made to better account for organic
emissions from combustion, in addition.
the procedures for evaluation of
facilities with multiple stacks were
revised to reduce over-regulation in
these situations.
A. Response to Comments
Numerous commenters to the 1987 and
1989 proposals objected to conservatism
of the calculated quantity Limits and/or
the 1% limit on hazardous waste firing.
The commenters stated that the
assumptions used in calculating the
exempt limits are overly conservative.
and that the 1% limit on firing of
hazardous waste it based on unrealistic
and unjustifiable conclusions. The
commenters. however, did not provide
data or analysis to support their
arguments that assumptions used in the
small quantity burner exemption (SQBE)
calculations and conditions (including
limits on the waste to be burned) for
exemption eligibility were too
restrictive. Absent technical support for
alternate approaches, the Agency
continues to believe that the approach
proposed in October 1989 is reasonable
and Appropriate. In addition, using less
conservative assumptions to derive the
exempt quantities could allow relatively
large amounts of hazardous waste to be
burned, a result somewhat at odds with
the statutory language referring to small
"quantities" of hazardous waste. See
J 265.108(a)(2) which limits the
maximum hazardous waste firing rate at
any time to 1% of the total fuel
requirements of the device on a volume
basis. See also I 266.108(a)(3) which
requires the hazardous waste to have a
minimum heating value of 5.000 Btu/lb,
as-generated, to ensure that the
exemption is limited to fuels as intended
by section 3004(q)(2)(3) and to ensure
adequate destruction of toxic organic
constituents.
One commenter requested credit for
the presence of air pollution control
devices (APCDs). The Agency believes
that it is no appropriate to allow credit
for APCDs because, without
requirements for an oversight of the
operation and maintenance of the
devices, there is no assurance that
collection efficiencies are being met
Four commenters to the 1987 proposal
urged EPA to delete the small quantity
burner exemption. These commenters
were concerned that the large number of
boilers and industrial furnaces burning
hazardous waste that do not have to
meet any design requirements would
have a detrimental effect on human
health and the environment. The Agency
continues to believe that the exemption
is protective of human health and the
environment because it is health-based,
incorporating quantity limits and
conservative assumptions designed to
be protective regardless of size and
location of the device, or conditions of
operation.
Two commenters stated that the
exemption should apply to facilities that
generate hazardous waste at off-site
facilities under the same ownership and
operational control. The Agency is
concerned, however, that contrary to
Congress's intent this approach could
allow a large quantity generator to
distribute their hazardous wastes in
small quantities to TSDFs (including
entities that are parent corporations.
joint ventures, subsidiaries of the
generator, etc.) that would then bum the
wastes without regulation.
Consequently, the final rule limits the
exemption to facilities that burn only
hazardous waste generated on-site.
One commenter to the 1987 proposal
urged the Agency to clarify that the 1%
limit on the hazardous waste firing is to
be applied only to unmixed hazardous
waste fuel not to a mixture of
hazardous and non-hazardous fuel The
Agency acknowledges the ambiguity in
the proposed rule language and intended
the proposal to require that the quantity
determination take into account only the
hazardous waste fuel prior to mixing
with a nonhazardous waste fuel
Today's final rule contains language to
that effect and requires the exempt
facility to keep records to document that
the quantity of hazardous waste prior to
mixing with a nonhazardous fuel
complies with the quantity limitations.
Six commenters to the 1988 proposal
suggested that quantity limits be baaed
on \% of the total fuel burned and not
the stack height which relies upon
dispersion only. The Agency, however.
continue* to believe that terrain-
adjusted stack height is the important
criterion, because it is possible that
even a 1% limit with large dispersion
and low stack height could pose a
threat to human health and the
environment
B. Basis for Today's Final Rule
In order to calculate allowable
exempt quantities under today's rule.
worst-case dispersion coefficients
(based on incinerator modeling), and an
HC unit risk factor of 2 x 10~* m'/jig
(baaed on a 10~* risk limit) wen
assumed, as proposed in the October
1989 supplemental notice. Allowable
emission rates of hydrocarbons (HCs)
were then back-calculated as a function
of effective stack height terrain type,
and land use. The assumption used in
this back-calculation was an HC
concentration in the stack gas of 150
ppmv at 99.99% ORE. Finally, the exempt
quantities were calculated using the HC
emission rates and an empirically-
derived ratio of combustion gas volume
to mass of waste. The most conservative
allowable emission rates calculated for
each stack height were then used as the
established quantity limits.
A detailed description of the
methodology used to derive quantity
limit* for the exemption is available in
the docket for the supplemental notice.
Aa mentioned above, the use of |
effective stack height to determine
eligible quantity limits reflect* one of
the revision* proposed in the October

Fodertl Register / Vol. 56, No. 35 / Thursday, February 21, 1991 / Rules and Regulations 7191
28.1989 supplemental notice. The
Agency notes that we have not
established separate exempt quantity
limits for the different terrain types and
land use classifications. Rather, the
revised quantities are based on
assumptions of terrain and land use that
result in the lowest (i.e., most
conservative) exempt quantities. We
believe that this conservative approach
is appropriate given that there would be
no EPA or State agency oversight of an
operator's determination of a facility's
terrain and land use classification. Some
key assumptions used to arrive at the
quantity limits are described below.
EPA evaluated the risks posed by
emissions of organic compounds, metals,
and hydrogen chloride, the parameters
controlled in the substantive regulations
promulgated in today's rule.** The
analysis demonstrates that the risks
posed by organic emissions from waste-
as-fuel activities are overwhelmingly
dominated by the risks posed by
carcinogenic (as opposed to
noncarcinogenic) waste constituents.
Accordingly, the initial evaluation
performed in support of the small
quantity burner exemption focused
exclusively on carcinogenic risks, on the
assumption that controls ensuring
insignificant risks from organic
carcinogenic emissions will ensure
protection against non-cardnogenic
releases. This assumption was
confirmed by evaluating the potential
risks from metals and hydrogen chloride
that would result when those quantities
of waste indicated by the risk analysis
for organic carcinogens were burned.
The risks from burning small
quantities of hazardous waste are
determined primarily by the following
factors:
• Composition of the waste stream
being burned:
• Toxicities and concentrations of
hazardous constituents in the waste
stream:
• Destruction and removal efficiency
achieved by the device:
• Local meteorology, which influences
the amount of dispersion of stack
emissions;
• Clustering and size of sources: and
• The effective stack height of the
device.
The values of these parameters can
and do very widely. Reasonable, worst-
case assumptions were made for these
parameters in the Agency's calculations
of exempt quantities and evaluation of
risks. In the risk analysis, EPA assumed
an acceptable cancer risk level of 1.0 X

10~* to an individual residing for 70
years at the ground level point of
maximum exposure to reasonable,
worst-case stack emissions. Reasonable,
worst-case dispersion coefficients based
on effective stack heights were used.
The dispersion coefficients were those
developed in the risk analysis for the
proposed amendments to the hazardous
waste incinerator regulations (See 54 PR
43752 and 55 FR17871). The dispersion
coefficients differ by terrain type, land
use, and effective stack height Separate
calculations were made for noncomplex
and complex terrain and urban and rural
land use. resulting in three different sets
of quantity eligibility limits for each
effective stack height. The rationale for
the assumptions used in the risk
analysis is discussed below.
1. Composition of Hazardous Waste
Stream
Composition data on hazardous
waste-derived fuels is scarce.
Information gathered by the mail
questionnaire survey and other industry
contacts indicate that most of the
materials burned are organic solvents
that are usually classified as hazardous
based on ignitability and/or toxicity.
The actual concentrations of
carcinogens in wastes burned by 21
facilities during EPA's field testing
program for boilers and industrial
furnaces ranged from 0 to 17% with an
average of approximately 4%.
The quantity of PICs measured In EPA
test burns was found to be independent
of specific POHC species and was •
function of hydrocarbon (HC] content of
the fuel only. This is supported by
comparisons made by MRI of PICs from
hazardous waste and fossil fuel
combustion. Since it is impossible to
differentiate between the PICs from fuel
and those from hazardous waste during
most tests, it was assumed that the
boilers in the EPA test burns were using
fuels of 100% HC and all PICs are the
result of hazardous waste burning.
Additionally, HC emissions are
presumed to be an acceptable
measurement of PICs; historic data
indicate that HC measures from 75 to
95% of all PICs emitted.
The hazardous waste was assumed to.
contain concentrations of cadmium.
chromium, nickel and lead that wen
obtained from the state sampling report*
of the Keystone Cement Company.
Arsenic, barium, and mercury
concentrations were based on 90th
percentile levels from the Engineering
Science Background Document
2. Toxicity of Hazardous Constituents
The average unit risk of those PICs
that were identified during EPA trial
burns was 1.0x10"* m'/pg. However, it
is likely that the PICs resulting from
incineration under the 99% DRE
assumption for the small quantity burner
analysis would have a higher toxicity
than those measured under the 99.99%
DRE in the EPA boiler tests. EPA
therefore estimates the unit risk for total
HCs to be 2.0X10'* mVpg. This
corresponds to a carcinogenic potency
of Qi* =0.07 for hydrocarbons (HC). As
explained in the October 1986 notice,
this potency factor was used rather than
a Qi* value of 1.0 for products of
incomplete combustion as originally
proposed in the May 6,1987 proposed
rule because the Agency was concerned
about possible nonconservative features
of PIC estimation. (See 54 FR 43730.)
3. Destruction Efficiency
The burner destruction efficiency
determines the quantity of unburned
hazardous wastes that will be emitted
from the stack. Assumed values for
boiler and furnace performance were
selected based upon review of test data
generated in support of this rule and
based on the professional judgment of
Agency staff members familiar with the
destruction and removal efficiencies
(DRE) typically achieved by boilers. It
was assumed that, in the worst case.
boilers and furnaces would only achieve
99% DRE •* of organic constituents. This
represents a very poorly performing
combustion device. In fact as explained
previously, most boilers and furnaces
can be expected to achieve 99.99% DRE
of organic waste constituents even when
operated under less than optimal
conditions.
4. Assumptions Regarding Metals and
Chlorine in Waste Fuels
A similar reasonable, worst-case
analysis was performed to evaluate the
potential risks posed by emissions of
toxic metals (including carcinogens) and
hydrogen chloride from small quantity
burners. As a result it was determined
that at the volume cut-offs specified by
the exemption and the assumed waste
concentrations as discussed above,
metals emissions caused by cofiring of
hazardous wastes would not pose a
significant risk. The analysis also
considered hydrogen chloride emissions
assuming a chlorine content of 50% in
the hazardous waste fuel The chlorine

content in actual hazardous wastes
seldom exceeds 3%; however, the
highest chlorine content measured in a
hazardous waste fuel fired in a boiler of
which EPA is aware was 43%. Predicted
ground level concentrations of HC1 also
did not exceed the reference aid
concentrations.
The assumptions used to determine
the effect of local meteorology/
dispersion and the clustering of sources
(stacks at the facility) are discussed in
the following section.
C. How the Exemption Is Implemented
1. Use of Terrain-Adjusted Effective
Stack Height
In the 1987 proposal, the Agency used
a set of assumptions about local
meteorology, dispersion modeling,
terrain conditions, etc., to determine
eligible quantity limitations. As
mentioned above, today's rule uses
terrain-adjusted effective stack height
along with the most conservative
assumptions of terrain and land use to
determine quantity limits for exemption
eligibility. See § 266.108.
2. Multiple Stacks
As explained in the October 1989
notice, in today's final rule the exempt
quantities for a facility with multiple
stack* from boilers or industrial
furnaces burning hazardous waste are
limited according to the following
equation:
n Actual Quantity Burnedu)
T _ .
i»1 Allowable Quantity Bumedu)
Where:
• n means the number of stacks
• Actual Quantity Burned, meanj tbt
waste quantity per month burned in
stack "I"
• Allowable Quantity Burned, meant the
maximum allowable exempt quantity for
lUck "l"
For example, if a site had two stacks
with effective stack heights [ESH] of 30
end 10 meters, the following equation
would hold:
X Y
— + —

Whew
• 140 and 40 an the exempt quantities

10 meters, respectively
• X Is the waste quantity burned in the
device with the 30 meter stack
• Y is the waste quantity burned In the
device with the 10 meter stack
In this example, if Y is burning 15
gallons/month, then X could burn no
more than 87.5 gallons/month.
D. Wastes Ineligible for Exemption
Boilers and furnaces burning
hazardous waste fuels containing or
derived from any of the following
dioxin-containing hazardous wastes are
not eligible for the exemption: EPA
Hazardous Waste Nos. F020, F021. F022.
F023. FO28. and F027. See
S 266.108(a)(4). Given the toxicity of
these wastes, EPA does not believe it is
appropriate to exempt facilities burning
them from regulation. Hazardous waste
fuels containing or derived from these
dioxin-containing wastes must be
burned at a 99.9999% destruction and
removal efficiency (ORE). We cannot
expect boilers and furnaces to achieve
that level of ORE when operating
outside of the Agency's regulatory
system.
£ Exemption of Associated Storage
Hazardous fuel storage practices prior
to burning vary from site to site. Many
facilities burning relatively large
quantities of hazardous waste fuels hold
the fuels in a storage system and then
pump the waste fuels through a
dedicated line into the combustion zone
of the boiler. Other facilities mix
hazardous waste fuels with other fuels
(typically virgin fuel oil) in • storage/
mixing tank prior to burning the blended
material. These tanks are not feasibly
emptied of hazardous waste every 90
days and so are in most cases ineligible
for the generator accumulation
provisions in § 262.34.
Under today's rule, facilities storing
unmixed hazardous waste fuels are
responsible for complying with all
applicable standards for the storage of
the hazardous waste fuel. Owners and
operators that are eligible for the small
quantity burner exemption and who mix
toxic hazardous waste fuels would.
however, be exempt from the storage
standards after such mixing, as
proposed. See $ 268.101 (c)(2). The basis
for this exemption is discussed below,
The Agency is promulgating an
exemption for storage of such storage/
mixing tanks (for small quantity
burners) in order for the small quantity
burner exemption in section
3004(q)(2)(6) to have a practical
application. Congress evidently
envisioned a class of facilities capable
of burning small amounts of hazardous
wastes safely absent regulation and
viewed such burning as a superior
means of managing these small amounts
of waste. Furthermore, assuming that
small quantity waste storage is
conducted safely, the Agency assui
that Congress also envisioned
exemption of the storage since
permitting storage would discourage
safe on-site burning just as much as
regulating the burning itself.
We believe that storage of small
amounts of hazardous wastes mixed
with virgin fuels would pose no
significant incremental risks over
storage of the virgin fuels. The monthly
volumes of hazardous waste hie!
covered by the small quantity burner
exemption, for example, represent less
than 1% of the fuel flow rate through
these tanks. Under these circumstances,
we think the statutory exemption can
reasonably be read to encompast this
limited class of storage practices as
well.
We note further that the Agency is
studying other situations where
hazardous waste-containing mixtures
may not be appropriately subject to
regulation and will consider whether to
issue rules addressing the issue . -
genetically. It appears to us justifiable to
address the question for the limited
class of burning facilities in advance of
other types of situations because
Congress has singled out small quantity
burning facilities for exemption whei
appropriate. We note further that to/
extent these small quantity waste-vi
fuel tanks are underground storage
tanks (as defined in RCRA section
9001(1)), they would be subject to
regulation under Subtitle I if they
contain petroleum.
F. Notification ojid Recordkeeping
Requirements
As proposed in the October 28.1989 •
supplemental .notice, the final rule
requires (conditionally) exempt small
quantity burners to provide a one-time
written notification to EPA (see
§ 266.108(d)) of their status as a small
quantity burner and a certification that
they are in compliance with the
requirements of 1266.108. To assist
enforcement efforts, the owner or
operator must also indicate in the
notification the maximum allowable
quantity that may be burned per month
as provided by { 266.108(a)(l). In
addition, the final rule requires small
quantity burners to keep records to
document that they comply with the
conditions of the exemption including:
quantities of hazardous waste burned
per month; quantities of hazardous
waste and other fuels burned at any
time to demonstrate conformance witim
the 1% hazardous waste firing rate lifl
and heating value of the hazardous ™
waste).

XL Exemption of Low-Risk Waste from
IpRE Standard and Partkulate Matter
^Emission SUndud
The final rule define* two type* of
"low-risk" wastes: (1) waste that is low
risk with respect to feed rate of
hazardous (Le.. appendix VHL part 281)
nonmetal constituents and, thus, is
exempt from the requirement to
demonstrate 9959% ORE; and (2) waste
that is low risk with respect to both
nonmetal constituents and metals (i.e-,
the waste meets the Tier 1 feed rate
limits for metals provided by
J 266.106(b)) and, thus, is exempt from
both the ORE standard and the 0.08 gr/
dscf particulate standard. See | 280.109.
The following sections explain these
exemptions and how they operate.
A. Exemption from Compliance with the
ORE Standard
In the May 6. 1987 proposed rule, the
Agency proposed a risk-based, site-
specific waiver of the ORE trial bum
and the flue gas CO limits for facilities
burning waste that poses insignificant
health risks absent those controls (52 FR
17002). Today's final rule retains the
exemption from the ORE standard, but
requires the facility to monitor CO
continuously and to comply with the
Tier I PIC controls of 126&104(b) (Le,
CO cannot exceed the 100 ppmv limit on
an hourly rolling average basis).
In the 1987 proposal. EPA explained
the basis for the ORE exemption for
boilers or industrial furnaces that burn
low-risk waste (52 FR 17002). After
further consideration, however, the
Agency believes that controls on
emissions of PICs are needed. This is
because a waste with low levels of toxic
organic constituents can nonetheless
pose significant health risk if it is burned
under poor combustion conditions
conducive to formation of PICs. Toxic
PICs can form from poor combustion of
nontoxic organic compounds.
The final rule does not allow a burner
to operate under the alternative CO limit
provided by S 266.104(c). which allows
higher CO levels provided that HC
levels do not exceed 20 ppmv, because
the Agency believes that only those
devices operating under best
demonstrated technology combustion
conditions should be granted an
exemption from the ORE requirement
(We note that this is consistent with the
CO restriction for the automatic waiver
of the ORE trial burn for boilers
operating under the special operating
conditions provided by f 266.110.)
Devices operating at CO levels above
100 ppmv on an hourly rolling average
are not operating under best
demonstrated technology combustion
conditions even if they can show that
hydrocarbon levels do not exceed 20
ppmv (or the HC limit established under
S 268.104(0). As discussed at proposal
(see 54 FR 43723 c.3). the 20 ppmv HC
level represents a demarcation between
good and poor combustion conditions.
HC levels under best demonstrated
technology combustion conditions
would generally be less than 5 ppmv on
an hourly rolling average basis.
B. Exemption from Compliance with the
Particulate Standard
Today's final rule provides a waiver
of the particulate standard for facilities
that both obtain the DRE standard
waiver and meet the Tier I requirement*
for all metals. (Because the PM standard
guards against risks from both adsorbed
organic compounds and metals, only
facilities with waste that is low risk for
both organic constituents and metals an
eligible for the PM waiver.)
The basis for imposing a particulate
standard on boilers and industrial
furnaces firing hazardous waste, a*
explained hi the October 28,1989
supplemental notice (54 FR 43710), is
primarily the concern over adsorption of
toxic organic* and metals onto the
emitted particulates. Consequently, the
Agency believes that an exemption from
the particulate standard for boiler* and
industrial furnaces is appropriate
provided that the facility can
demonstrate that emissions of toxic
organic* and metals do not pose
unacceptable human health risk*.
C. Eligibility Requirements
Three eligibility requirement* for the
low-risk waste exemption were detailed
in the 1987 proposed rule. Many
commenten objected to the first of these
requirements, that 50 percent of the fuel
fired in the boiler or industrial furnace
must consist of oil. natural gas, coal, or
other fossil fuels derived from these
fuel*. These commentera requested that
EPA allow the cofiring of various other
fuels, including tall oil off-specification
fuel oils, and wood chips.
Although some of these fuel* may
provide a hot stable flame that will
support good combustion, the Agency is
concerned that others may not In
today'* rule, the Agency is requiring for
this exemption the same condition* on
the primary fuel a* required for the
special operating requirement* for
boilers seeking the automatic waiver
from a DRE trial burn (see section HA3
of part three of this preamble): a
minimum of 50% of the fuel fired to the
boiler must be high quality "primary"
fuel consisting of fossil fuel* or fuels
derived from fossil fuels, tall oil. or, if
approved by the Director on a case-by-
case basis, other nonhazardous fuel
comparable to fossil fuel, and all such
primary fuels must have a minimum as-
fired heating vahie of 8.000 Btu/lb.
The two remaining eligibility
requirement*, that the hazardous waste
must have an as-fired heating value of at
least 8,000 Btu/lb, and that the waste
must be fired into the flame zone of the
combustion chamber, are being
promulgated as proposed in 1987. The
reasons for these requirements are the
same as discussed in section ILA.3 of
part three of this preamble in the
context of the automatic waiver of the
DRE trial bum for boiler*.
D. How the Low-Risk' Waste Exemption
Works
1. Constituents of Concern
The low-risk waste exemption is
intended to exempt a waste from either
or both the DRE standard and the
particulate standard if the owner/
operator demonstrate* that absent
regulatory controls (i.e, under a
reasonable, worst-case emissions -
scenario), emissions from the facility
will not result in ambient level* of toxic
organic compound* and/or metals that
exceed acceptable levels. The organic
constituents of concern are the
hazardous organic compound* listed in
appendix Vm of 40 CFR part 261 and the
metal* of concern are the 10 regulated
metal*.
2. Estimation of Worst-Case Emissions
The requirements for estimating
wont-case emissions were discussed in
the May 1987 proposed rule and are
being promulgated in today's rule with
slight modifications.
To estimate reasonable, wont-case -
emissions of toxic organic constituent*
in hazardous waste fuel an owner or
operator must (1) Identify every
nonmetal appendix VIH constituent that
could reasonably be expected to be
found in the waste: and (2) assume a
reasonable, worst-case destruction and
removal efficiency (DRE) for each
constituent of 99.9 percent in calculating
the wont-case emissions (by
considering waste concentration and
feed rate) from the stack for each
constituent This assumed DRE of 99.9
percent is less conservative than the
proposed 99 percent assumption in the
1987 notice. The Agency is making this
change in response to the many
commenten who objected to the 98
percent DRE assumption. Specifically.
the commenten' objection waa that 99J0
percent was the wont DRE measured by
the Agency in it* non»teady-etete testing
of boiler* operated 'irMVt* intentionally
-------
7194 Federal Register / Vol. 58, No. 35 / Thursday, February 21, 1991 / Rules and Regulation*
upset (i.e., high CO and smoke)
conditions. The Agency believes that
changing the assumed ORE from 99
percent to 99.9 percent is justified
because today's rule, unlike the 1987
proposal does not provide a waiver of
the continuous CO emission monitoring
(GEM) requirements. Compliance with
continuous CO monitoring requirements
will ensure that these devices do not
operate under upset conditions and will
achieve a ORE of at least 99.9 percent
The Agency has eliminated the
proposed requirement that emissions of
products of incomplete combustion
(PICs) be estimated using a ratio of PICs
to principal organic hazardous
constituents (POHCs). As explained hi
the April 1989 notice (54 FR 43730), use
of the PIGPOHC ratio may not be a
conservative method for estimating PIC
emissions.
An estimate of worst-case emissions
is not necessary for metals. To be
eligible for the exemption from the
participate standard, the waste must be
low-risk with respect to organic
compounds and must meet the Tier I
metals feed rate limits. See 1266.106(b).
Those metals feed rate limits assume
that all metals fed into the device are
emitted.
3. Dispersion Modeling
Dispersion modeling must be used to
predict the maximum annual average
ground level concentration of each toxic
nonmetal compound La the waste using
procedures identical to those required to
implement the Tier III metds controls.
See 26e.l09(a)(2)(iii)(A).
4. Acceptable Ambient Levels
Predicted maximum annual average
ground level concentrations of each
toxic nonmetal compound may not
exceed levels the Agency proposed as
acceptable for purposes of this rule. The
acceptable ambient concentrations wen
developed for carcinogenic and
noncarcinogenic compounds using die
same procedures used to develop the
RACs and 10~* RSDs for the 10 toxic
metals.
To demonstrate that the
noncarcinogenic nonmetal compounds
listed in appendix IV of the rule do not
pose an unacceptable health risk, the
predicted ground level concentrations
cannot exceed the levels established in
that appendix.
To demonstrate that the carcinogenic
nonmetal compounds listed in appendix
V of the rule do not pose an
unacceptable health risk, the sum of the
ratios of the predicted ground level
concentrations to the levels established
in the appendix cannot exceed 1.0. This
is because the acceptable ambient levels
established in appendix V are based on
a 10"' risk level To ensure that the
summed risk from all carcinogenic
compounds does not exceed 10~» (i.e., 1
in 100.000), the sum of the ratios
described above must be used.
To demonstrate that other compounds
for which the Agency does not have
adequate health effects data to establish
an acceptable ambient level are not
likely to pose a health risk, the predicted
ambient level cannot exceed 0.1 M8M*
This is the 5th percentile lowest
reference air concentration for the
compounds listed in appendix IV of the
rule.
5. Constituents with Inadequate Health
Effects Data
At the time of the 1987 proposal, the
Agency had data adequate for
establishing RACs and RSDs for only
about 150 of the over 400 compounds
listed in appendix vm, part 261. In the
preamble to the May 1987 proposal, EPA
stated that to be eligible for the
exemption, health effects data (i.e*
RACs and RSDs) must be available for
each constituent in the waste. In
response to comments concerning the
inadequacy of current health effects
data to establish a RAC or RSD for a
large number of compounds, we have
established in today's rule a
conservative RAC value for such
constituents determined as the 5th
percentile lowest RAC for all of the
nonmetal appendix VDL part 281.
constituents—0.1 jig/m* (see note to
appendix IV of the final rule). EPA
believes that this approach will be
protective of human health and the
environment and will not unreasonably
restrict owners/operators from
eligibility for the exemption,
XIL Storage Standards
A. Permit Standards for Storage
Under the administrative controls for
hazardous waste marketers, burners,
and blenders of hazardous waste burned
in boilers and industrial furnaces
promulgated on November 29,1985. and
codified in subpart D of part 286, EPA
subjected existing burner storage
facilities (effective May 29,1986) to only
the interim status standards of part 265.
The permit standards of part 284 were
not applied to existing storage facilities
in order to avoid two-stage permitting,
given that today's rule for permitting
boiler and industrial furnace facilities
was under development at that time.
The Agency wanted to avoid requiring a
boiler or industrial furnace owner or
operator to obtain a permit for then*
hazardous waste fuel storage facility
and to soon thereafter obtain another
permit for operation of the boiler or
industrial furnace under today's rule.
Today's rule does, therefore, subject
such existing burner storage facilities to
the permit standards of part 284. See
{ 266.101(c).
Numerous comments on the May 6,
1987 proposed rule to subject burner
storage units to the permit standards of
part 264 agreed that the interim status
standards currently in force are not
adequate and permit standards are
needed Several commenters were
concerned about the potential
mishanding of waste fuels stored on-site
in and around residential areas. One
cbmmenter requested that prebum
transport and storage regulations for
hazardous waste apply to all hazardous
waste blends, mixtures, or diluted
hazardous materials.
With the promulgation of today's rule.
all hazardous waste storage units will
be subject to applicable part 264 and 265
standards. Since hazardous waste
storage units standards are designed to
be protective of human health and the *
environment regardless of the location
of the facility, on-site storage associated
with boilers and Industrial furnaces
burning hazardous waste is not
restricted to areas in or around
residential areas. These standards apply.
to the storage of any hazardous waste
blends, mixtures, or dilutions that will
be burned at these facilities, due to the
"mixture rule" of 40 CFR 281A Whereas
nonindustrial boilers were previously
prohibited from burning hazardous
wastes unless they were operated in
conformance with the incinerator
standards of subpart O of parts 264 or
285, today's rule eliminates the
distinction between industrial and
nonindustrial boilers. Consequently,
today's rule establishes standards that
are protective when hazardous waste is
burned in any boiler.
One commenter recommended that
the final rule allow the 90-day "on-site"
accumulation provision to include
wastes received at the DIP from off-site.
company-owned locations. The 90-day
accumulation provision referred toby
the commenter is contained in 40 CFR
28i34(a) and only applies to generators
of hazardous wastes. The Agency does
not intend to apply this provision to
hazardous waste treatment storage, or
disposal facilities.
B. Consideration of Requirement for
Liquid Waste Fuel Blending Tank*
In the October 26,1980 supplemental
notice, the Agency requested comment
on a requirement that all boiler and
industrial furnaces use blending and
surge storage tanks (Le, other than other
-------
Federal Register / Vol 56, No. 35 / Thursday, February 21, 1991 / Rules and Regulations 7195
•modei of watte fuel transfer) to avoid
Bow interruptions and waste
Stratification which could affect the
ability of a combustion device to meet
performance standards. The majority of
commenten opposed requiring blending
and surge storage tanks for BIFs and
suggested that such a requirement
would not be necessary to ensure
compliance with performance
standards. Several commenters believed
that a uniform requirement for tanks,
containers, and/or surge tanks may not
be universally appropriate. These
commenters noted that some secondary
materials such as lead add batteries,
flue dust and various scraps and slags
cannot be transferred to furnaces from a
tank or container system. Another
commenter suggested that in some
instances, such as feeding incompatible
wastes, direct transfer may be
preferable due to health and safety
concerns. A few commenten concurred
with this view, but felt that storage and
blending tanks should be required in all
other instances. One commenter
suggested that storage tanks should be
required only if transport vehicles do
not meet Department of Transportation
requirements, secondary containment it
not used in transfer operations, and if
Operations are not covered by site-
•petific contingency or SPCC plans. One
Commenter agreed that hazardous
wastes should generally be fed from
storage tanks and supported a final rule
that would allow a "window of
opportunity" to install storage tanks,
thus providing an incentive for a
company to reduce their reliance on
direct burning from transport vehicles.
In today's rule, the Agency is not
requiring storage and blending tanks for
boilers and industrial furnaces burning
hazardous waste because we continue
to believe that such tanks are not
requisite to demonstrating conformance
with the emission standards of
8I 260.104 through 266.107. However, as
indicated in the supplement to the
proposed rule. EPA believes that
facilities that install blending and
storage tanks may be better able to
control flow interruptions and waste
stratification. Consequently, boilers and
industrial furnaces with blending and/or
storage tanks may operate with greater
efficiency and thereby may more readily
meet performance standards for
emissions.
We also note that, once an owner/
operator is in interim status, the part A
application may be revised to convert
Ifrom direct transfer operations to the
Pise of storage units. See discussion in
section VTILD of Part Three of the
preamble.
C. Standards for Direct Transfer
Operations
In the October 28.1989, supplement to
the proposed rule. EPA identified
permitting authorities' concerns about
the practice of feeding hazardous waste
fuels directly from transport vehicles to
boilers and industrial furnaces. These
concerns included: (1) The potential for
fires, explosions, and spills during
transfer operations; and (2) the
stratification of waste in the transport
container and the potential for waste
fuel flow interruptions which, in turn,
could affect the ability of the burner to
consistently provide efficient
combustion of the waste. EPA requested
comment on two approaches to regulate
direct transfer operations. One approach
was for permit writers to use the RCRA
omnibus authority to establish
additional permit conditions as
necessary to ensure adequate protection
of human health and the environment
from such operations. The other
approach was to require that facilities
burning hazardous waste use blending
and surge storage tanks to avoid the
flow interruptions and waste
stratification, which would address
permit writers' concerns.
In the April 27.1990 Federal Register
notice, EPA noted that commenten on
the October 1989 notice stated that
controls on transfer operations were
needed during interim status. As a
result, the Agency requested comment
on the need and appropriateness of
regulating direct transfer operations
under interim status standards for
containen and tank systems of subparts
I and I of part 265. EPA received
numerous comments in response to
these solicitations. The majority of
commenten recommended that EPA
allow direct transfer with proper
controls and restrictions, such as: (1)
Allow direct transfer approval for
facilities granted interim status or a
RCRA operating permit; (2) establish
direct transfer standards similar to
subparts I and) of 40 CFR part 265 for
facilities with a contingency or SPCC
plan; and (3) allow direct transfer during
test burns alone. Some respondents
suggested that instead of allowing direct
transfer. EPA should require storage and
blending tanks for all facilities burning
hazardous waste.
The Agency is today promulgating
standards regulating direct transfer
operations. See i 266.111. The Agency
believes that these standards will
adequately address potential risks to
human health and the environment
EPA considers direct transfer
operations to be a part of the hazardous
waste firing system, not a storage
activity. Hence, facilities that are not
subject to the burner standards of
S i 266.102 (permit standards) or 266.103
(interim status standards) are not
subject to the direct transfer standards.
Examples of facilities not subject to the
direct transfer standards are small
quantity burners exempt from regulation
under I 266.108, metals reclamation
furnaces deferred under | 266.100(c),
and coke ovens exempt under
S 266.100(b)(4).
These direct transfer standards
reference extensively the subpart I
container standards and the subpart I
tank standards of parts 264 and 265 and
will apply equally to facilities operating
under a permit as well as those
operating under interim status. The
regulations address the area in which
transport vehicles are located and
piping and other ancillary equipment
(termed "direct transfer equipment" in
today's rule) used to transfer waste from
the vehicle to the burner. The standards
provide general operating requirements
and controls on equipment integrity,
containment and detection of releases,
response to leaks or spills, design and
installation of new direct transfer
equipment and closure.
1. General Operating Requirements
Facilities that directly transfer
hazardous waste to boUen and
industrial furnaces from transport
vehicles must comply with general
operating requirements that specify safe
management practices for handling
incompatible wastes, spill prevention
controls, and automatic waste feed
cutoffs. These general operating
requirements apply to both
containerized and bulk hazardous
waste. General performance standards
for safe operation in today's rule include
measures for conducting direct transfer
operations such that fire, explosion.
violent reactions, and other conditions
that could threaten human health or the
environment do not occur. Direct
transfer from open-top containen is
prohibited. Direct transfer equipment
which is any device that distributes,
meters, or controls hazardous waste
flow between a transport vehicle and a
BIF. must also be closed except when
necessary to add or remove the waste.
Safe management practices for handling
incompatible wastes are also required.
Transport vehicles or direct transfer
equipment holding ignitable or reactive
hazardous waste must be located at
least 50 feet from the receiving facility's
property IUM*

2. Inspections and Recordkeeping
All equipment and areas where direct
transfer occurs must be inspected hourly
for leaks during direct transfer
operations. Control equipment direct
transfer equipment monitoring data, and
other equipment ensuring compliance
with direct transfer standards must also
be inspected hourly. Finally, the rule
provides recordkeeping requirements to
document results of inspections.
We note thst only daily inspection is
required under subpart J of parts 264
and 265 for tank systems (i.e., piping.
valves and other direct transfer
equipment). EPA is requiring hourly
inspections of direct transfer operations
because, unlike tank systems that use
hard piping, direct transfer operations
use flexible hoses and quick change
coupling devices that have a greater
potential for leaks or spills.
3. Equipment Integrity
Equipment integrity requirements
address direct transfer equipment (e.g.,
piping or conveyors from the transport
vehicle to the burner). The standards
promulgated today require the transfer
of waste to other equipment if
equipment holding hazardous waste
leaks or is in poor condition, and specify
safe management practices for
transferring wastes to other containers
or transport vehicles. An assessment is
required of existing direct transfer
equipment that does not meet the
secondary containment requirements
discussed below to determine if the
direct transfer equipment is leaking or
unfit for use and must be certified by a
qualified, registered professional
engineer. If equipment is found to be
leaking or unfit for use. the owner/
operator must comply with the
requirements addressing responses to
leaks or spills.
4. Cont&inment and Detection of
Releases
The rule requires secondary
containment for underground direct
transfer equipment. See { 266.111(e)(l).
Inspections and leak tests of direct
transfer equipment and recordkeeping
requirements are also required. Existing
direct transfer equipment subject to the
secondary containment requirements of
§ 265.193 (by reference in 8 266.111(e)(l)
of today's rule) must comply with those
secondary containment requirements
within two yean after the effective date
of the rule. EPA believes that two yean
(30 months from promulgation) is a
reasonable amount of time to enable
wnen and operators to retrofit existing
equipment with secondary containment
as necessary given that direct transfer
operations generally do not involve the
use of extensive equipment subject to
secondary containment
5. Response to Leaks or Spills
Action required to be followed in the
event of a leak or spill are based on
those required in subpart), part 265. See
I 266.11(e)(5). Should a leak or spill
occur, equipment use must cease (to
prevent the Cow or addition of wastes
into the direct transfer equipment or
secondary containment system) and the
system must be inspected to determine
the cause of the release. The waste must
be removed from the direct transfer
equipment or secondary containment
system and visible releases to the
environment must be contained. In the
event of a leak or spill the Director must
be notified of the incident in writing.
Secondary containment repair, or
closure of the leaking equipment and
certification of major repairs must be
provided.
6. Design and Installation of New
Equipment
New direct transfer equipment must
meet the design and installation
standards specified in today's rule as
defined in 8 265.192 for tank systems.
See | 266.111(e)(4) in today's rule
referencing that section. The standard*
include: Specifications for assessing the
design of new direct transfer equipment:
backfill requirements for new
underground direct transfer equipment
tightness tests; equipment support and
protection requirements; corrosion
protection; and written certification that
these requirements have been met
7. Closure
Today's rule applies by reference the
closure requirements for direct transfer
equipment provided by { 265.197 (except
paragraphs (c)(2) through (c)(4)). See
5 286.111(e)(6). That section requires the
removal or decontamination of waste
residues, system components, and
contaminated soils, structures, and
equipment
XHL Applicability of the Bevill
Exclusion to Combustion Residues
When Burning Hazardous Waste
Under the Agency's existing
regulations, wastes that are derived
from the treatment of listed hazardous
wastes are also considered to be
hazardous unless and until they are
delisted (see 40 CFR 261.3(c)(2) and
(d)(2)J. The combustion or processing of
hazardous waste in a device that uses
elevated temperatures as the primary
means to change the chemical physical
or biological character or composition of
the hazardous waste, is a type of
treatment no matter what type of davice
is used in the process, or for what
purpose the waste is burned or
processed. Accordingly, under the
Agency's existing rules, residues from
thermal combustion (or processing) of
listed hazardous wastes remain the
listed hazardous wastes until they are
delisted.
When the device burning hazardous
waste is (1) a boiler burning primarily
coal or other fossil fuels. (2) an
industrial furnace processing primarily
ores or minerals, or (3) a cement kiln
processing primarily raw materials, the
applicability of the Bevill exclusion must
be considered (see RCRA section
300l(b)(3)(A)(i-iii)). The Bevill exclusion
refers to residues resulting from burning
or processing certain materials whereby
the residues are not considered to be
hazardous waste at this time because
they require special study to determine
whether they should be regulated under
subtitle C.
To determine whether the Bevill
exclusion continues to apply when the..
devices described above bum or process
hazardous waste, today's final rule
promulgates the case-by-case
determination involving a two-part test
as discussed in the October 1989
supplement to the proposed rule. See
i 266.112. Under this test owners and
operators must determine on a site-
specific basis whether the co-
combustion of hazardous waste has
significantly affected the character of
the residue. The residue is considered to
be significantly affected if both: (1)
Concentrations of toxic (appendix VIIL
part 261) compounds in the waste-
derived residue an significantly higher
than in normal (i.e.. without burning/
processing hazardous waste) residue:
and (2) toxic compounds are present in
the waste-derived at levels that could
pose significant risk to human health. If
the case-by-case determination
demonstrates that the residue has been
significantly affected (or if the owner or
operator does not obtain data and
Information adequate to support a
demonstration that the residue has not
been significantly affected), such
derived-from residues are subject to
regulation as hazardous waste because
the residues are no longer the type of
material Congress commanded the
Agency to study before regulation. Such
residues are no longer deemed to be
from processing ores or minerals.
burning fossil fuels, or making cement
Rather, they are from treating hazardous
waste.

basis for applying the Bevill exclusion to
derived-from residues, the evolution of
-------
Fatten* Register / Vol. 56, No. 35 / Thursday, February 21, 1991 / Roles and Regulations 7197
^he Agency's interpretations on the
Applicability of the Bevill exclusion to
'waste-derived residues, and how
today's case-by-case determination
works.
A. Basis for Applying the Bevill
Exclusion to Derived-From Residues
A number of comments questioned
whether the Agency has the legal
authority to determine that some
residues from coprocessing hazardous
waste with Bevill raw materials could
remain excluded under the Bevill
amendment pending completion of the
section 8002 studies. Because the
Agency's previous determination of this
question (50 PR 49190 (Nov. 29.1985))
could have been more fully explained,
the Agency has decided to reopen the
question in this rule and to respond to
the public comments.
The Agency's consistent position on
this issue is that so long as the
processing of hazardous waste does not
significantly affect the character of the
waste residues as high volume/low
hazard, then those wastes can remain
excluded under the Bevill amendment
Put another way, the wastes can
potentially remain the type of material
that Congress told the Agency to study
before imposing subtitle C regulation.
Instead of focusing on the question of
whether coprocessing hazardous waste
affects the composition of the residues
from a Bevill device, some commenters
would have it that the mixture and
derived-from rules apply to the residues,
so that the residues are subject to
subtitle C (assuming listed wastes are
coprocessed) regardless of the actual
effect of burning hazardous waste. At
the least the statute does not compel
this result In the case of utility boilers
burning fossil fuels, the statute states
explicity that wastes "generated
primarily from the combustion of coal or
other fossil fuels" is to be excluded. See
section 3001(b)(3)(A)(i). Thus, some type
of co-combustion is expressly
authorized. With respect to the two
remaining categories of Bevill waste
(wastes from processing ores and
minerals and cement km dust), the
Bevill amendment (section
3001(b)(3)(A}) does not use the term
"primarily", but does not expressly
address the question of whether the
exemption applies when the residues
are produced in part from burning
hazardous waste. Thus, read literally,
dust from a cement kiln that bums
hazardous waste along with normal raw
materials could be termed "cement kiln
dust" •«
If there were doubt on this point the
Agency is convinced that it is dispelled
by the 1984 amendments. Sections
3004(q)(l) and 3010(a) both state
explicitly that "(n)othing in this
subsection shall be construed to affect
or impair the provisions of section
3001(b)(3)" (the Bevill amendment). This
language would be meaningless unless it
allowed some residues from Bevill
devices burning hazardous wastes
(specifically hazardous waste fuels) to
remain within the scope of the Bevill
amendment Although commenters
argued, based on passages from the
legislative history, that the provision
should not be given this natural
meaning, the Agency does not find the
argument persuasive. Rather, the
legislative history appears to state that
Bevill devices burning hazardous waste
fuels will be subject to the emission
standards developed pursuant to section
3004(q). See H. Rep. No. 198,98th Cong.
1st Sess. 41: S. Rep. No. 284,98th Cong.
1st Sess. 37. Today's rules accomplish
that result
At the same time, the Agency is
concerned about reading the Bevill
amendment in a manner that gives it
undue scope, such as by allowing Bevill
devices to serve as a dumping ground
for other hazardous wastes. We do not
view the interpretation adopted today
as allowing the exemption to have
undue scope. In the first place.
emissions from the Bevill device itself
are regulated. Second, the facility
becomes subject to the facility-wide
corrective action provisions of sections
3008(h) and 3004(u) by virtue of
regulation of the combustion activity.
Thus, potential problems relating to
mismanagement of waste residues must
be evaluated and addressed no later
than during the permitting process.
Most importantly, the Agency believes
that the reading adopted strikes a
reasonable balance between the terms
of the Bevill amendment and other
provisions and regulations relating to
hazardous waste management A
reading that would disqualify residues
from the Bevill amendment if any
hazardous waste is burned in the device
would exalt form over substance by
barring from Bevill eligibility a residue
that was not discernably affected by
burning hazardous waste. Given that
such material could be exactly the high
volume/low hazard residue that
Congress told the Agency to study
before regulating, EPA does not agree
with an interpretation that automatically
forecloses it from Bevill status.11 In
addition, use of Bevill devices for
combusting hazardous wastes provides
needed treatment capacity for a number
of hazardous wastes, and the Agency
would be reluctant to adopt an
interpretation that discouraged safe
processing of hazardous waste by
necessarily Imposing hazardous waate
disposal costs on residues that might not
be affected by the hazardous waste
combustion.
For all of these reasons, therefore, the
Agency is reading the statute in a way
that does not automatically disqualify
residues from coprocessing hazardous
wastes in Bevill devices from eligibility
for Bevill exempt status.
B. Evolution of Interpretations
To determine whether the Bevill.
exclusion continues to apply when the
devices described above •• burn
hazardous waste fuel the Agency stated
in 1985 (see 50 FR 49190 (Nov. 29,1985))
that the exclusion continues to apply as
long as the hazardous waste is burned
for energy recovery (i.e., not for
destruction). The underlying principle
for this determination was that when
hazardous waste is used as fuel the
character of the residue would continue
to be determined by the Bevill material
(e.gn coal, ores or minerals, or cement
raw materials) being burned or
processed. Thus, the residue should
remain within the Bevill exclusion
pending special study before it could be.
regulated under subtitle C.
In the May 0,1987 proposed rule (52
FR 17012-013), the Agency suggested
refining these determinations to address
residues from industrial furnaces
processing ores or minerals and that
also process hazardous waste for
material* recovery, and residues from
cement kilns that may process
hazardous waste as an ingredient
" EPA doeenoi accept the argument that the

7198 Federal Register / VoL 56, No. 35 / Thursday, February 21. 1991 / Rules and Regulations
Under that proposal, such residues
would remain within the Bevill
exclusion provided that at least 50
percent of the raw material fed to the
device consisted of a virgin ore. mineral.
or normal raw material. However.
residues from devices burning
hazardous waste for the purpose of
destruction (i.e.. for neither energy nor
materials recovery) would not qualify
for the Bevill exclusion.
The Agency has evaluated these
interpretations of the applicability of the
Bevill exclusion to waste-derived
residues in light of its stated principle
that residue that results from cobuming
hazardous waste and Bevill raw
materials should remain within the
Bevill exclusion provided that the
character of the residue is determined
by the Bevill material (i.e., the residue is
not significantly affected by the
hazardous waste). As discussed in the
October 1989 supplement to the
proposed rule (54 PR 43733-36), the
Agency does not believe that its data
base for making these interpretations is
sufficient to ensure that, in every case,
the residue would not be significantly
affected by the hazardous waste.
Further, the Agency has reconsidered
whether the interpretation that residues
generated by the subject devices when
burning waste for destruction are not
within die Bevill amendment is
consistent with the stated principle.
Consequently, the Agency proposed in
the supplemental notice to require case-
by-case determinations of the effect of
burning hazardous waste on residuals.
That case-by-case approach is
promulgated in today's rule.
C. Case-By-Case Determinations
We discuss below which devices are
eligible for the Bevill exclusion of
residues and how the two-part test
works for determining whether
combustion of the waste has
significantly affected the residue.
1. Eligible Devices
Until further studies were completed.
Congress intended to exclude from
subtitle C regulation residues from: (1)
Devices that burn primarily fossil fuel;
(2) industrial furnaces that process ores
or minerals: and (3) cement kilns. As the
Agency reads these provisions, to be
eligible for exclusion from subtitle C
regulation under the Bevill amendment
the waste-derived residue must be
generated from: (1) A boiler burning
primarily coal *T (2) an industrial
furnace processing primarily ores or
minerals (otherwise, residues could not
be said to come from processing ores
and minerals, but rather from processing
other materials), or (3) a cement kiln
processing primarily raw materials. To
implement the provision that, to be
eligible for the Bevill exclusion the
device must burn primarily Bevill
material. EPA is requiring that a boiler
must bum at least 50 percent coal an
industrial furnace must process at least
50 percent ores or minerals, and at least
50 percent of the feed stock to a cement
kiln must consist of normal raw
materials. This requirement also
confirms the Agency's long-standing
interpretation that the Bevill exclusion
applies only to primary facilities and not
to secondary facilities such as
secondary smelters.** See { 286.112(a).
2. Two-Part Test
Today's rule requires a case-by-case
determination as to whether the
hazardous waste being burned or
processed significantly affects the
character of the residue with respect to
inorganic and organic toxic (i.e..
appendix VllL part 261) constituents.
The residue is considered to be
significantly affected if both: (1)
Concentrations of toxic (Appendix VIII)
compounds in the waste-derived residue
are significantly higher than in normal
(i.e., without burning/processing
hazardous waste) residue: and (2) toxic
compounds are present in the waste-
derived residue at levels that could pose
significant risk to human health. Part
One of the test need not be conducted if
the waste-derived residue passes Part
Two of the test (i.e.. if the health-based
concentration limits are not exceeded).
Such a waste would still meet the high
volume/low hazard Bevill threshold
a. Part One—Comparison with
Normal Residues. Part One of the test
requires a comparison of hazardous
waste-derived residues with normal
residues to determine if toxic
compounds are present at statistically
significant higher levels. See
5 266.112((b)(l). The toxic compounds of
concern are any compound listed on
appendix VIIL part 261. that may
reasonably be expected to be a
constituent in the hazardous waste plus
the list (see appendix VIII to the rule), of

procedures are provided in Test
Methods for Evaluating Solid Waste.
Physical/Chemical Methods (SW-C46)
incorporated by reference in $ 260.11(a).
The rule requires the use of a
statistical test to compare the
concentrations of toxic constituents in
samples of normal (without burning/
processing hazardous waste) residues
with samples of waste-derived residues.
In the statistical test the 95th percent
confidence interval about the mean of
the normal residue concentrations (using
a "t" distribution) is used to determine
the upper 95th percent confidence
interval about the mean. Procedures that
must be used to determine the upper
95th percent confidence interval about
the mean are prescribed hi "Statistical
Methodology for Bevill Residue
Determinations" in Methods Manual for
Compliance with the BIF Regulation,
incorporated in today's rule as appendix
IX of part 266. A minimum of ten
composite samples must be obtained
and analyzed to represent the normal
residue in order to effectively calculate^
the upper 95th percent confidence
interval about the mean. This is the
concentration that the waste-derived
residue may not exceed to pass Part
One of the test The waste-derived
residue must be characterized by
composite samples with a composite
period not to exceed 24 hours to ensure
that residues are managed properly and
promptly (i.e.. as exempt residues or
hazardous waste) and to provide for
effective enforcement The sampling
approach must be based on (and be
consistent with) representative sampling
protocols described in SW-846 and must
be documented by recordkeeping.
If operating conditions change so that
concentrations of toxic compounds in
normal residue may (would have)
decrease(d). the owner and operator
must re-establish the "baseline"
concentrations in normal residue and
use the lower baseline levels for the test
This is necessary to ensure that owners/
operators do not use the most
contaminated raw materials in order to
burn more hazardous waste, and then
switch back to their normal raw
materials.

b. Part Two,—Comparison With
Health-Based Limits. Part Two of the
test requires a comparison of the
concentration of toxic constituents in
the waste-derived residues with health-
based limits the Agency has established
in appendix VII to the rule. The
comparison is made to determine if
toxic compounds in the waste-derived
residue are present at levels higher than
the health-based limits. The toxic
compounds of concern are the same as
for Part One of the test—any compound
listed on appendix VIII. part 261. that
may reasonably be expected to be a
constituent in the hazardous waste plus
the list (see appendix Vin to the rule) of
organic compounds that are common
products of incomplete combustion
(PICs) from burning hazardous waste.
The total concentration of each
nonxnetal compound of concern in the
waste-derived residue must be
compared with the health-based limit In
addition, the concentration of each
metal of concern in an extract from the
Toxicity Characteristic Leaching
Procedure (TCLP) must not exceed the
health-based limits.
The Agency does not have adequate
health effects data (e.g.. MCLs. RfDs,
unit risk values) to establish health-
based limits for many compounds listed
in appendix VUL part 261.
Consequently, we have conservatively
established a health-based limit for such
compounds based on the 5th lowest
percentile value of the health-based
values for nonmetal compounds
established in appendix VII to the rule.
That value is 0.002 ug/kg. This is the
same approach EPA used to establish a
RAC for compounds where insufficient
health effects data were available to
establish a RAC or RsD for the
compound.
The rule requires the use of total
concentrations of nonmetal compounds
rather than extract concentrations for
the test of health significance because of
burning toxic nonmetal compounds in
these devices should be to destroy the
compounds. (Use of total nonmetal
concentrations thus serves as a partial
check that combustion is being
conducted properly.] The health-based
limits for the metals in appendix VII of
the rule are the Toxicity Characteristic
(TC) limits (see I 281.24) for those
metais for which TC limits have been
established. To establish health-baaed
limits for the other metals, the Agency
applied the came 100 fold dilution factor
to leachate concentrations used to
establish the TC limits. The Agency has
also used this same dilution factor in
assessing whether mineral processing
wastes satisfy the low hazard prong of
the Bevill test See 54 FR 38630 (Sept 1,
1989).
To determine if the concentrations of
toxic compounds in the waste-derived
residues are higher than the health-
based limits, owners and operators must
obtain and analyze composite samples
of waste-derived residues with a
composite period not to exceed 24 hours.
The sampling approach must be based
on (and be consistent with]
representative sampling protocols
described in SW-846 and must be
documented by recordkeeping.
D. Recordkeeping
Owners and operators must maintain
for a period of three years records of
sampling and analyses of residues to
support claims that the waste-derived
residue retains the Bevill exclusion.
E. Other Consideration*
l. Generic Determinations
In the October 26,1988 supplement to
the proposed rule, the Agency requested
data and information that it could use to
support: (1) Generic determinations of
levels of toxic constituents in normal
(i.e.. generated without burning/
processing hazardous waste) residues:
and (2) generic determinations that
certain waste-derived residues are not
significantly affected by burning/
processing hazardous waste, and, thus.
remain excluded without the need to
make the case-by-case demonstration.
a. Normal Residues. After review of
comments on the 1989 supplemental
notice, the Agency concluded that it is
not practicable to establish generic
concentrations of toxic constituents in
normal residues. Commenten noted that
then were so many site-specific
variables that affect the concentration of
toxic constituents in normal residues
that this approach was not workable.
Variables include the type of industrial
furnace, type of fuels burned, and type
and source of raw materials used by
industrial furnaces. The Agency initially
considered establishing generic
concentration levels in normal residues
to avoid giving an advantage to facilities
that use fuels or raw materials with high
(i.e.. higher than normal for the industry)
levels of toxic constituents. Normal
residues from such facilities would have
high levels of toxic constituents. Thus.
waste-derived residues from such
facilities could also have high levels of
toxic constituents. Consequently, such
facilities could burn/process hazardous
waste with high levels of toxic
constituents without losing the Bevill
exclusion of residues. We note that
enforcement officials will give priority
consideration to those facilities whose
residues fail part 2 (health-based limits)
of the test to determine Bevill
applicability and rely on part 1
(comparison with normal residues) to
retain the exclusion. Owners and
operators must be able to support at
any time, that the nonhazardous waste
feedstreams being fed into the device
when hazardous waste is fired are the
same (or would not decrease the
concentrations of toxic constituents in
residues) as those Tired when the
concentrations of toxic constituents in
normal residues were determined. If the
concentrations of toxic constituents in
nonhazardous feedstreams decrease
significantly from those concentrations
when the normal residue was generated
for purposes of establishing normal
concentrations of toxic constituents (or
if design or operating conditions change
such that levels of toxic constituents in
normal residue could decrease
significantly), then the owner/operator
must establish new. lower,
concentrations for normal residue.
b. Excluded Residues. The Agency
also concluded that it is not practicable
to make generic determinations that
certain waste-derived residues are not
significantly affected by burning or
processing of hazardous waste and, so,
remain excluded. This approach is not
workable given that the exclusion would
have to be conditioned on a number of
factors including: (1) The composition.
foetTrlte, and method of feeding the
/harzardoui waste: (2) the type of device;
(3JJheycomposition. feed rate, and
- method of feeding any other fuels: and
(3) the composition, feed rate, and
method of feeding any raw materials.
The data base to support such
determination is not available.
Moreover, any such generic exclusion
that is necessarily conditioned on so
many factors would be of little practical
use to the regulated community given
the variability of normal operations.
2. Burning for Destruction
The case-by-case approach to
determine the effect of cobuming on
residues from Bevill devices focuses on
the residues that are actually generated
rather than on the purpose for which the
hazardous waste is burned. Thus,
residues generated from burning
hazardous waste in boilers and
industrial fumances for the purpose of
destruction *° an eligible to retain the

Bevill exclusion. The Agency's historic
approach to the issue of cogenerated
residues has been to focus on the
character of the residues to ascertain
what determines their character—the
Bevill material or the hazardous waste
being burned/processed (see 50 FR
49190 (November 29.1987)). The statute
itself does not directly specify that the
purpose of the burning is a relevant
criterion, but instead states that certain
types of waste are excluded from
subtitle C regulation pending completion
of required special studies. Since the
Bevill devices would still be engaged in
the Bevill activity, and composition of
the residues would potentially be
unaffected, the Agency sees no absolute
bar to allowing Bevill status for such
residues.

units. Today's rule defines carbon
regeneration unit and incinerator (see
§ 260.10) to ensure that both direct flame
and nonflame thermal carbon
regeneration units are regulated as
thermal treatment units under the
interim status standards of part 285.
subpart P. and the permit standards of
part 264 subpart X.
One commenter expressed concern
that the thermal treatment standards of
subpart X were vague. EPA disagrees
and points out that subpart X. part 264
coven miscellaneous hazardous waste
management units that do not or may
not fit the description of any of the units
covered by other pnrt 264 regulations.
Without subpart X, these unregulated
units could only operate as interim
status facilities and could not be fully
permitted, thereby preventing the
construction of new units or some
expansions of existing units. EPA
recognized that some types of new units
that were not previously allowed to be
constructed could reduce risks to human
health and the environment from the
management of hazardous waste.
Promulgation of subpart X generic
permitting standards was intended to
allow such construction and flexibility
for technical development and
innovation and to cover diverse
technologies and units. The subpart X
standards specify that health and
environmental safety must be a primary
concern during the management of
hazardous wastes in miscellaneous
units. If the need arises, the Agency may
develop specific technology standards in
the future (see 52 FR 48964, December
10,1987). Although several commentera
supported the application of part 264,
subpart O incinerator standards to
direct flame and nonflame devices, EPA
has decided against this since
demonstration of confonnance with the
ORE standards (and the proposed CO/
THC standards) may not be achievable
or warranted for carbon regeneration
units considering the relatively low
levels of toxic organic compounds
adsorbed onto the activated carbon.
B. Definition of Carbon Regeneration
Unit and Revised Definition of
Incinerator
Several commenters requested that
EPA consider revising the definition of a
carbon regeneration unit so that certain
units used for air emissions control wet
oxidation, and general recycling, would
not be regulated. Activated carbon unit*
used as air emission control devices of
gaseous industrial process emission!
will not necessarily be regulated
because trapped organics in such
columns are not hazardous wastes
because the gas originally being treated
is not a solid waste (it is an uncontained
gas ••). and therefore any condensed
organics do not derive from treatment of
a hazardous waste. (The nongas
residues from these devices could be
hazardous wastes if they are listed or if
they exhibit a characteristic, however.)
However, regeneration or reactivation of
carbon used to control air emissions
from hazardous waste treatment,
storage, or disposal facilities (e.g.. under
40 CFR parts 264 and 265, subpart AA.
June 21.1990.55 FR 25454) is subject to
regulations as a RCRA thermal
treatment unit.
We considered whether other units
truly are engaged in reclamation, or
whether the regeneration of the carbon
is just the concluding aspect of the
waste treatment process that
commenced with the use of activated
carbon to adsorb waste contaminants,
which are now destroyed in the
"regeneration" process (just as rinsing

out a container of hazardous waste is a
stage in the storage process and does
not constitute recycling of the
container). Irrespective of whether these
units are better classified as waste
treatment or recycling units (or whether
the units are flame or nonflame devices),
we are concerned, as indicated above,
that emissions from the regeneration
process can pose a serious hazard to
public health if not properly controlled.
and therefore are clarifying today that
they are regulated as thermal treatment
units.
We note that this revision also applies
to those carbon regeneration units that,
while in active service treating
wastewater, meet the definition of
wastewater treatment units in { 280.10.
Such units are exempt from RCRA
permitting standards while treating
wastewater. However, these units are
not exempt from RCRA regulation when
they are being regenerated because they
are not treating wastewater during the
regeneration process. Rather, the
activated carbon columns themselves .
are being treated thermally. The thermal
regeneration unit is subject to part 285,
subpart P (existing units) or part 264,
subpart X (new units).
C. Units in Existence on the Effective
Date of the Rule are Eligible for Interim
Status
Although certain carbon regeneration
units may technically have met either
the 1980 or 1985 definitions of
incinerator, the Agency believes that
then has been legitimate doubt as to
these units' regulatory status (which is
why the Agency undertook this
rulemaking to clarify the status). The
units might potentially have been
classified as incinerators, thermal
treatment units, or perhaps exempt
recycling units. It would also have been
confusing to interpret the rules in a
manner that carbon regeneration units
were not all regulated in the same way,
given that their functions and activities
are roughly identical whether or not the
units are direct-fired. In fact the most
natural classification of these units, and
the one the Agency intended, is as
thermal treatment units. (EPA does not
believe that these are recycling units,
but rather that regeneration is a
continuation of the waste treatment
process, that process consisting of
removal of pollutants by adsorption
followed by their destruction. Ncr does
the Agency believe that incinerator
standards make technical sense for
these devices, as noted above). In
addition, few if any of these units have
actually been regulated as incinerators
in practice.
-------
Federal togutet / Vol 56. No. 35 / Thursday, February ZL. 1991 / Rules and Regulations 7201
For these reasons. EPA is Ending
pursuant to § 270.10(e)(2) that there was
substantial confusion as to which
owners or operators of carbon
regeneration units were required to
submit a part A application and that this
confusion is attributable to ambiguities
in the subtitle C rules. Accordingly, such
owners and operators may submit part
A applications by the effective date of
today's regulations and be eligible for
interim status under pan 265, subpart P
(assuming they meet remaining
requirements for interim status
eligibility, and the facility is not already
subject to interim status for other units).
U. Sludge Dryers
In today's rule, the Agency is
clarifying the regulatory status of sludge
dryers. In particular, the rule adds a
definition of "sludge dryer" to $ 260.10
and amends the definition of
"incinerator" in § 260.10 to specifically
exclude sludge dryers.
On November 17.1980 (45 FR 76074),
EPA suspended the applicability of the
RCRA permitting requirements (40 CFR
part 122, which is now codified as part
270) and hazardous waste management
facility standards (40 CFR parti 284 and
265) to owners and operator* of devices
meeting the definition of "wastewater
treatment unit" in 40 CFR 280JO and
270.2.
Since promulgation of this wastewater
treatment unit exclusion from RCRA
permitting requirement*, the Agency has
received numerous requests to
determine if certain types of units
satisfy the definition of "wastewater
treatment unit" and. therefore, would
not require a RCRA permit. Many of
these requests have concerned the
regulatory status of thermal treatment
units, particularly sludge dryers.
Commenters have also requested
clarification of the regulatory status of
sludges from thermal treatment units.
Most of the requests have been from
owners and manufacturers of sludge
dryers. The Agency believes that
approximately 40 sludge dryers are
currently being used in the metal
finishing industry to dehydrate metal
hydroxide sludges (EPA Hazardous
Waste F006) generated in the treatment
of wastewater.
In response to these inquiries. EPA
distributed policy memoranda to the
Regional offices explaining that a sludge
dryer is included within the scope of the
wastewater treatment tank exclusion.
provided that it meets the definition of
"wastewater treatment unit" (See
OSWER Policy Directives 9501S2-1A
and 950&51-1A. available upon request
from tha RCRA Hotline.) In addition.
with respect to the status of Uw sludges
themselves, they are hazardous waste if
identified or listed (including by
application of the mixture and derived-
from rules) and are subject to regulation
when removed from the tanks.
Despite the original November 17.
1980 preamble discussion and the policy
clarification, the regulatory status of
sludge dryers has continued to be
unclear. One reason for the confusion is
because it is not clear whether a sludge
dryer satisfies the third component of
the definition of wastewater treatment
unit (i.e.. whether it meets the definition
of a "tank" or "tank system"). The
Agency has determined that sludge
dryers that are integrally equipped with
feed or discharge hoppers that provide
for an accumulation of waste satisfy the
definition of "tank system." '* Based on
information available to EPA at this
time, it appears that most sludge dryers
are so equipped. (Those sludge dryers
that are not so designed may still be
considered tanks, but a case-by-case
decision must be made.) The Agency
has also determined that other types of
equipment not obviously meeting the
"tank" definition, such as presses.
filters, sumps, and other types of
processing equipment are covered
within the meaning of the term "tank" or
"tank system" when used in the context
of this exclusion (see OSWER Policy
Directive 9503.52-lA).
Another reason that tha regulatory
status of sludge dryers has been the
subject of many questions may be
because some sludge dryers technically
meet the current definition of an
"incinerator." although EPA never
intended to regulate direct-flam* (or
nonflame) sludge dryers as incinerators.
When EPA amended tha definition of
"incinerator" to use physical design
criteria rather than a primary purpose
test (i.e> purpose of burning) to define
an incinerator, it did not intend to bring
sludge dryers under regulatory control
a* incinerators. (See 50 FR 625, |anu*ry
4.1985. indicating that the revised
definition would not bring large
numbers of devices other than
incinerators under incinerator
standards.) Under the former primary
purpose definition, sludge dryers were
not incinerators. Although under the
1985 revised definition of incinerator
sludge dryers could be classified as
incinerators, this was not EPA's
intention. The Agency is clarifying this
ambiguity by clearly regulating all

nonexempt sludge dryers (i.e.. those not
meeting the definition of "wastewater "
treatment unit" under today's rule, as
discussed below) under the interim
status standards of part 285, subpart P
('Thermal Treatment"), and the permit
standard* of part 284. subpart X
("Miscellaneous Units"). See 55 FR
17866 (April 27.1990) for details. Given
that such units managing hazardous
waste always were subject to some type
of regulation, they are not newly eligible
for interim status as a result of today's
clarification.
Even though as a result of this
amendment sludge dryers are
potentially subject to regulation under
subpart P of part 265 and subpart X of
part 284 as other thermal treatment
units, sludge dryers that meet the
$ 260.10 definitions of "wastewater
treatment unit" and "tank" or "tank
system" continue to be exempt
wastewater treatment units under
{§ 264.1(g)(6) and 283.1(c)(10). The
Agency believes that virtually all sludge
dryers meet the tank/tank system
definition and. therefore, would be
exempt when used as part of a
wastewater treatment system.
A. July 1990 Proposed
To better clarify the regulatory status
of shidge dryer*, the Agency proposed
on July 18,1990 (55 FR 29280) a
definition for "sludge dryer" to clearly
distinguish them from other thermal
treatment units: Sludge dryer means any
enclosed thermal treatment device that
is used to dehydrate sludge and that has
a maximum total thermal input of 1.500
Btu/lb of sludge treated on a wet-weight
basis.
In the same notice, the Agency also
proposed to amend the definition of a
wastewater treatment unit to say that
sludge dryers were the only thermal
treatment devices (heretofore) meeting
the definition of a wastewater treatment
unit that were exempt from regulation.
Today's rule clarifies that sludge
dryers meeting tha definition of a
wastewater treatment unit are exempt
from regulation (by promulgating a
definition of sludge dryer and revising
the definition of incinerator to exclude
sludge dryers). EPA also proposed a
further clarification that other devices
that use heat to treat wastewaters were
not to be considered eligible for the
wastewater treatment tank exemption.
The Agency indicated without
discussion, that it had not intended for
such units to be eligible for the
exemption and mat the proposal was a
simple clarification which reflected
common understanding within the
Agency and the regulated community.
-------
7202 Federal Regbter / VoL 56, No. 35 / Thursday, February 21. 1991 / Rulet and Regulations
Commenters disagreed with this
asseismeat of the regulations, and the
Agenc- has since studied the issue in
more c ":th. It appears that the Agency
was mi.-.aken in its assessment both of
the current intended scope of the rule
and of common understanding of what
the rule covers. With respect to such
devices as evaporators and steam
strippers used in wastewater treatment
the Agency has in fact traditionally
regarded such units as eligible for the
wastewater treatment exemption. See 55
FR at 25467 (June 21.1990). Commenters
likewise indicated their understanding
that current rules exempt such devices.
Given the narrow scope of the
proposal, the clear indication that any
change would not be a clarification of
existing rules (as indicated) but rather a
potentially far-reaching alteration, and
the absence of any discussion (or study)
of whether a substantive change in
regulatory status of these devices is
warranted, EPA cannot go forward.
Consequently, we are not adopting any
other part of the definition of
wastewater treatment unit discussed in
the 1990 notice.
B. Summary of Public Comments
EPA received comments regarding the
status of sludge dryers in response to
the April 27,1990 BIF notice and the July
18,1990 notice discussed above.
Many of the Commenters to these
notices supported the inclusion of sludge
dryers in the wastewater treatment unit
(WWTU) definition. The commenters,
however, requested clarification on
whether units similar to sludge dryers
(e.g.. evaporators) would also be eligible
for the WWTU exclusion. As discussed
above, other devices using heat that
meet the definition of wastewater
treatment unit would continue to be
exempt from RCRA regulation (except,
of course, an incinerator, boiler, or
industrial furnace burning hazardous
waste).
Eleven commenters to these proposals
stated that the maximum 1.500 Btu/lb
thermal input requirement in the sludge
dryer definition is too low. Citing low
thermal efficiencies (especially for
indirect-fired dryers), these commenters
recommended thermal input
requirements ranging from 1.700 to 3,300
Btu/lb.
After consideration of the
commenters' concerns and further
review of the technical background
information on the thermal input limit,
the Agency is today revising the thermal
input limit to 2,500 Btu/lb wet sludge.
"he Agency believes that depending on
the nature of the treatment system, the
thermal input to a bonafide sludge
dryer (i.e., • device that is not an
incinerator) can be as high as 2.500 Btu/
Ib.
Several commenters also requested
that EPA clarify that the total thermal
input limit was not to include the
heating value of the sludge itself given
that a number of sludges that are dried
have as-fired heating values of 1,000 to
2.700 Btu/lb. The Agency agrees. The
final rule explicitly excludes the heating
value of the sludge from the 2£00 Btu/lb
limit on thermal input With this
clarification, however, we note that the
primary purpose test—dehydration—is
the primary distinction between a
sludge dryer and an incinerator. This is
because a sludge incinerator can readily
meet the thermal heat input limit of 2.500
Btu/lb when the heating value of the
sludge itself is not included. However,
the primary purpose of a sludge dryer is
dehydration while the primary purpose
of an incinerator is volume reduction to
produce an ash residue. Thus, we
believe that the definition in today's rule
adequately distinguishes between
sludge dryers and incinerators.
Nevertheless, it should be noted that
any person claiming the wastewater
treatment unit exemption for a sludge
dryer must have documentation to
support that the primary purpose of the
device is to dehydrate sludge, not to
destroy sludge to produce an ash
residue.
The Agency received many responses
to its request for comments on whether
it is necessary to specify a minimum
percent volume reduction in the
definition of a sludge dryer. Although
one commenter stated that a percent
volume reduction should be specified in
the sludge dryer definition, twelve of the
commenters stated that such a
requirement would be arbitrary,
confusing, unworkable, and costly to
enforce. Two of the commenters stated
that a minimum percent weight
reduction would be more appropriate. In
today's rule, the Agency has decided not
to specify a minimum percent volume
(or weight) reduction in the definition of
a sludge dryer. The Agency believes that
such a specification would be difficult to
support and would not be needed to
distinguish sludge dryers from
incinerators.
Several commenters stated that the
Agency should address emissions of
volatile organics from units such as
sludge dryers. In addition, two
commenters recommend a 1,000 Btu/lb
thermal input limit for the device to
control volatile emissions from sludge
dryers. EPA recognizes the need to
address volatile emissions from sludge
dryers and intends to evaluate
alternatives for regulating these units at
a later date. However, because this rule
simply clarifies that EPA intended for
sludge dryers that meet the definition of
a wastewater treatment unit to be
exempt from the RCRA rules, it would
be inappropriate to address volatile
organic emissions at this time.
Nonetheless, sludge dryers that do not
meet the definition of a wastewater
treatment unit (e.g., sludge dryers that
are not a part of a wastewater treatment
facility that is subject to regulation
under either section 402 or 307(b) of the
Clean Water Act) are subject to
regulation as thermal treatment units
under subpart X of part 264. Under those
standards, the Agency may apply
controls on volatile organic (and other)
emissions as necessary to protect
human health and the environment
After considering comments on the
proposed sludge dryer definition, EPA is
today promulgating the following
definitions:
Sludge dryer means any enclosed
thermal treatment device that is used to
dehydrate sludge and that has a
maximum total thermal input excluding*
the heating value of the sludge itself, of
2,500 Btu/lb of sludge treated on a wet-
weight basis.
Incinerator mean* any enclosed
device that (1) uses controlled flame
combustion and neither meets the
criteria for classification as a boiler,
carbon regeneration unit or a sludge
dryer, nor is listed as an industrial
furnace: or (2) meets the definition of
infrared incinerator or plasma arc
incinerator.

A. AISI Petition
The American Iron and Steel Institute
(AISI) petitioned EPA with respect to
the practice of recycling tar decanter
sludge by the following means:
1. Applying the sludge to coal prior to
or just after charging the coal into the
coke oven; and
2. Combining the sludge with coal tar
prior to its being sold.
The coke and the coal tar are often

9 281.2(c)(2)(t)(B). These hazardous
waste fuels have been exempt from
regulation under | 291.6(a)(3)(vii) and 50
FR 49170-171 (November 29. 1985). The
AISI has requested that EPA not classify/
such coke or coal tar as solid wastes.
AISI submits that recycling the decanter
sludge in this manner does not

Federal Regular / Vol 56. No. 35 / Thursday. February 21. 1991 / Rules and Regulations 7203
Scantly affect the concentration of
: metal and organic constituents of
5e coke or coal tar. EPA has indicated
that waste-derived fuels could be
classified as products under such
circumstances, "since the more waste-
derived fuels from a process are like
products from the same process
produced by virgin materials, the less
likely EPA is to classify the waste-
derivsd fuel as a waste." SO FR 49189
(Nov. 29,1985). To support its request,
the AISI submitted data on the metals
and organic constituents in coke, coal
tar, and tar decanter sludge both with
and without sludge recycling, the data
and the Agency's response are
discussed below.
B. Process Description
Coke used for making iron is
manufactured through the destructive
distillation of coal in ovens. A typical
oven holds aproximately 13 tons of coal
which is heated to a temperature of
about 2000'F. Generally 20 to 100 ovens
are located adjacent to each other in a
"coke oven battery." The destructive
distillation or "coking" process takes
about 15-18 hours. During that time
period, about 20-35 percent of the coal is
converted to coke oven gas (COG)
•hnsisting of water vapor, tar. light oils.
Havy hydrocarbons, and other chemical
Compounds. The COG is collected from
the top of the coke oven and. in most
cases, sent to the by-product plant via
the coke battery main. The COG is then
cleaned by removing wastes and by-
products prior to being burned, generally
in the coke oven under-filing system. As
a first step in the COG cleaning process,
the coal tars, consisting of heavy
hydrocarbons, are condensed from the
gas. In addition, most of the participate
that escapes from the ovens is collected
in the tar. This paniculate is believed to
consist principally of coal fines. The
particulate or solids are then removed
from the tar in the tar decanter. The coal
tar is then burned as fuel or sold for UM
in various products such as roofing
cement The sludge has been listed as
EPA Hazardous Waste No. K087 and is
disposed of or recycled either by mixing
with coal prior to being charged to the
coke oven or mixing with coal tar after
physical processing (grinding) prior to
sale.
Approximately 8-12 gallons of tar are
produced per ton of coke. In addition.
approximately one pound of tar
decanter sludge is produced for every 40
pounds of tar produced.
fe Basit for Approval of the AISI
petition
The AISI submitted data from metal
and organic chemical analyses for the
coke, coal tar, and tar decanter sludge
from four plants. The Agency reviewed
these results and determined the
following:
1. The recycling of tar decanter sludge
by application to the coal charge does
not appear to have a significant effect
on the chemical composition of coke:
2. The organic chemical composition
of the tar decanter sludge does not
appear to be significantly different from
the coal tar; and,
3. The concentration of one metal,
lead, in the sludge appears to be slightly
higher than in the coal tar. However, the
increase does not appear to be
statistically significant due to the high
variability of the concentration values.
Based on the above and the fact that
there is such a small quantity of sludge
relative to the quantity of coke and coal
tar produced by the coking process. EPA
believes that sludge recycling, as
described here, does not significantly
affect the concentration of toxic metals
and organic constituents in coal tar or
coke. Furthermore, coke, coal tar, and
the decanter tank tar sludge are similar
materials formed in a single process and
contain the same contaminants. In this
circumstance, when the coke and the
decanter tank tar sludge are very nearly
the identical substance and. moreover.
come from a single process, the Agency
is warranted in exercising its discretion
to determine that this management of
the sludge is "not part of the waste
diposal problem", and hence that the
coke product is no longer a RCRA solid
waste. American Mining Congress v.
EPA. 907 F. 2d 1179,1186 (D.C Cir. 1990).
Therefore, in today's rule. EPA is
classifying such coke and coal tar as
products, not wastes. Aa a result the
coke and coal tar will be excluded under
40 CFR 261.4 from the definition of solid
waste and not subject to RCRA
hazardous waste management
regulations, when used as a fuel. A
necessary corollary to this action is also
to exclude the coking process from
regulation when K087 is used as an
ingredient to produce coke. Given that
K087 is for practical purposes just like
other materials used to produce coke
and comes the the same process as
these other materials, it would be
anomalous to assert RCRA control over
the coking process. Again, this form of
sludge management—which is the same
as raw material management—does not
appear to EPA to be part of the waste
disposal problem.*4 (In addition, coke

of the Clean Air Act and RCRA

views RCRA regulation of this practice
as inappropriate in any case.)
This exemption applies only to the
waste-derived fuels and only when
derived from tar decanter sludge. K087.
Thus the tar decanter sludge. K087. is
subject to full RCRA regulation prior to
recycling. In addition, the exemption
does not extend to coke or coal tar
produced from hazardous waste (e.g.,
spent solvents) other than tar decanter
sludge, EPA Hazardous Waste K087.
IV. Regulation of Landfill Gns
In the November 29,1985 final rules
regulating hazardous waste burned for
energy recovery, the Agency indicated
that gas recovered from hazardous
waste landfills that is burned for energy
recovery in boilers or industrial furnaces
is not regulated under the waste-as-fuel
rules. 50 FR 49171. EPA took this action
in order to study further the extent to
which there might be jurisdictional
limits on the Agency's authority under
section 3004(n) of RCRA to regulate
gaseous emissions from hazardous
waste. Id In today's rule, we are
amending this language slightly by
indicating that the exemption also
applies to gas recovered from solid
waste landfills. Therefore, gas recovered
from a solid waste landfill that exhibits
a hazardous characteristic would also
be exempt from today's rule when
burned for energy recovery in a boiler
and industrial furnace.
In addition, the Agency solicited
comment in the May 6,1987 proposed
rule, on whether the hydrocarbon phase
of the condensate removed from
recovered gas should also be exempt
from regulation when burned as fuel (52
FR 17021). Two commenters responded
that the condensate contains chemical
constituents similar to fossil fuels such
as kerosene or gasoline and that the
handling and burning of the gas
condensate poses no significant hazard
to human health. The commenters
encouraged the Ageny not to regulate
the hydrocarbon phase of the landfill
gas condensate unless the hydrocarbons
exhibit a subtitle C characteristic of a
hazardous waste. However, data ou
condensate composition provided by
one respondent was vague and
represented only one source of
condensate. Absent adequate data EPA

Facilities that wish to burn a landfill gas
condensate may consider whether they
are eligible for the small quantity burner
exemption promulgated in this rule.
V. Definitions of Infrared and Plasma
Arc Incinerators
Today's rule establishes definitions
for infrared and plasma arc incinerators
and revises the definition of incinerator
to explicitly include these devices. As
discussed in the April 27.1990 proposed
amendments to the incinerator
standards (55 FR at 17869-70), EPA is
clarifying that these devices are
incinerators rather than (other) thermal
treatment units subject to regulation
under subpart X of part 264 (or subpart P
of part 265 for interim status units)
because: (1) although these devices use
nonflame sources of thermal energy to
treat waste in the primary chamber, they
invariably employ controlled flame
afterburners to combust hydrocarbons
driven off by the primary process (and,
thus, they meet the definition of an
"incinerator" under (260.10); and (2) the
incinerator standards are workable and
protective for these units.
We note that today's action merely
.arifies the regulatory status of these
devices. It does not subject them to
regulation for the first time: they have
been regulated since 1980. Thus, interim
status is not reopened for these devices.

enforcement authority under sections
3008.7003 and 3013 of RCRA. although
authorized States have primary
enforcement responsibility.
Prior to the Hazardous and Solid
Waste Amendments of 1984 (HSWA). a
State with final authorization
administered its hazardous waste
program entirely in lieu of EPA
administering the Federal program in
that State. The Federal requirements no
longer applied in the authorized State,
id EPA could not issue permits for any
-adlities in the State which the State
was authorized to permit When new,
more stringent Federal requirements
were promulgated or enacted, the State
was obliged to enact equivalent
authority within specified time frames.
New Federal requirements did not take
effect in an authorized State until the
State adopted the requirements as State
law.
In contrast under section 3006(g) of
RCRA. 42 U.S.C. 6926(g). new
requirements and prohibitions imposed
by HSWA take effect in authorized
States at the same time that they take
effect in nonauthorized States. EPA is
directed to carry out those requirements
and prohibitions in authorized States,
including the issuance of permits, until
the State is granted authorization to do
so. While States must still adopt
HSWA-related provisions as State law
to achieve or retain final authorization,
the HSWA applies in authorized States
in the interim.
The majority of today's rule is
promulgated pursuant to section 3004(q]
of RCRA. a provision added by HSWA.
(The provisions that are not
promulgated pursuant to HSWA are the
provisions for sludge dryers, carbon
regeneration units, infrared incinerators,
and plasma arc incinerators.) Therefore,
the Agency is adding the requirements
(except the non-HSWA provisions) to
Table 1 in i 271.1(j) which identifies the
Federal program requirements that are
promulgated pursuant to HSWA and
that take effect in all States, regardless
of their authorization status. States may
apply for either interim or final
authorization for the HSWA provisions
identified in Table 1. as discussed in the
following section of this preamble.
B. Effect on State Authorizations
As noted above, EPA will implement
the majority of the provisions of today's
rule in authorized States until they
modify their programs to adopt these
rules and the modification is approved
by EPA. Because these provisions of the
rules an promulgated pursuant to
HSWA. a State submitting a program
modification may apply to receive either
interim or final authorization under
section 3008(g)(2) or 3000(b),
respectively, for these provisions on the
basis of requirements that are
substantially equivalent or equivalent to
EPA's. The procedures and schedule for
State program modifications for either
interim or final authorization are
described in 40 CFR 271.21. It should be
noted that all HSWA interim
authorizations will expire January 1,
1993. (See | 271.24(c).)
The provisions of today's rule that an
not promulgated pursuant to HSWA—
provisions for sludge dryers, carbon
regeneration units, infrared incinerators,
and plasma an incinerators—are not
effective in authorized States. Thus,
these requirements will be applicable
only in those States that do not have
final authorization. In authorized States,
the requirements will not be applicable
until the State revises its program to
adopt equivalent requirements under
State law.
40 CFR 271.21(e)(2) requires that
States that have final authorization must
modify their programs to reflect Federal
program changes, and must
subsequently submit the modifications
to EPA for approval. The deadline by
which the State must modify its program
to adopt the HSWA portion of today's
rule is July 1.1993 if a statutory change
is not needed, or July 1,1994 if a
statutory change is needed. The
deadline by which the State must
modify its program to adopt the non-
HSWA portion of today's rule is July 1.
1992 if a statutory change in not needed,
or Jury 1,1993 if a statutory change is
needed These deadlines can be
extended in certain cases (40 CFR
271.21(e)(3)). Once EPA approves the
modification, the State requirements
become Subtitle C RCRA requirements.
States with authorized RCRA
programs may already have
requirements similar to those in today's
rule. These State regulations have not
been assessed against the Federal
regulations being promulgated today to
determine whether they meet the tests
for authorization. Thus, a State is not
authorized to implement these
requirements in lieu of EPA until the
State program modification is approved.
Of course, States with existing
standards may continue to administer
and enforce their standards as a matter
of State law.
In implementing the Federal program
for the HSWA portion of today's rule.
EPA will work with States under
cooperative agreements to minimize
duplication of efforts. In many cases,
EPA will be able to defer to the States in
their efforts to implement their
programs, rather than take separate
actions under Federal authority.
States that submit their official
applications for final authorization less
than 12 months after the effective date
of these standards are not required to
include standards equivalent to these
standards in their application. However,
the State must modify its program by the
deadlines set forth in i 271.21(e). States
that submit official applications for final
authorization 12 months after the
effective date of these standards must
include standards equivalent to these
standards in their application. 40 CFR
271.3 sets forth the requirements a State

IL Regulatory Impact*
A. Cost Analysis
I. background
publication of the proposed
regulations in May 1987, the Agency
cxjunined the projected compliance
cojits. economic impacts, and risk
reductions associated with the proposed
rules. This effort consisted of a detailed
elimination of the pre-proposal draft as
it was drafted in mid-1988 and a
supplement prepared in late 1986 •* that
exiimined several changes in tax policy
anil regulatory approach that occurred
aftijr the first analysis was completed.**
The analyses estimated that of the
approximately 1.000 BIFs identified as
firing hazardous wastes, approximately
20 percent were likely to discontinue
buiaing hazardous wastes because of
the rules, 60 percent would burn small
amounts of waste and would qualify for
the small quantity burner exemption
(SCjBE], and the remaining 15 percent
would obtain full permits. Because the
Fund IS percent of devices represent
larjje facilities, however, the impact on
the total quantity of waste burned
»Jd be small For example, under the
ise case" scenario, although 20
rcent of the devices would
discontinue burning hazardous wastes
and a number of other devices would
reduce the quantity of hazardous waste
they combust in order to qualify for the
SQ13E. only 3 percent of the quantity of
wante combusted in the absence of
regilations would be diverted to other
devices. The mid-1986 analysis
estimated that under this scenario, the
aggregate after-tax cost of compliance to
Individual firms would be $&2 million
per year and that the before-tax social
cost would be $8.2 million per year.
Uruter other sets of assumptions (Le>
othisr scenarios), these costs were likely
to t« higher, but in all cases were
estimated to be less than $100 million
per year.
Based on these analyses, the Agency
concluded that the total social costs,
impact on market competition, and die
impact on small businesses were such
thai; the proposed regulations did not
constitute a major rule, and that a
formal Regulatory Impact Analysis as
described in Executive Order 12291 was
not required.

Wwte A> Foal Twhakal Steader*". >«nuiy 10B7.
A number of comments on the
economic analysis were received from
affected businesses and other groups.
Most of these commenters contended
that the cost of compliance had been
underestimated by the Agency. Based
on these comments, as well as changes
made in the final regulation compared to
the proposed requirements, the Agency
has reexamined and updated the earlier
analyses.
2. Revised Cost Analysis
As indicated earlier, there have been
a number of changes made in the
regulations mat are expected to increase
the tost of compliance." In addition, the
Federal tax code was changed in late
1986. the cost of goods and services to
the economy as a whole has increased
due to inflation, and the estimated cost
of specific requirements associated with
the BIF regulations have been
reexamined. The new analysis focused
on assessing the impact of changes in
compliance costs on typical facilities,
and did not reexamtne the impact of
these changes on the selection of
regulatory options by individual
facilities. In addition, no effort was
made to explicitly examine the impact of
the final rules on the economic
competitiveness of individual firms or
industries, nor on the reduction in public
health risks.
The primary changes that have
occurred hi the regulations subsequent
to proposal have been revised
requirements for continuous emission
monitoring of CO and HC; addition of
the PM standard, interim status
compliance procedures, and limits on
emissions of several additional metals
and Ck and increases inrecordkeeprng.
sampling, and analysis requirements.
The impact of these changes plus the
impact of tax code changes and inflation
on the before- and after-tax costs of the
BIF regulations axe summarized in Table
1. When combined with the original
"base case" cost estimates prepared in
198*. the revised cost estimate for the
promulgated rule is $15.2 million per
year before taxes and $10.3 million per
year after-taxes.
The increased cost for CO and HC
monitoring reflects the costs for
installation of a more comprehensive
CO monitoring system than was
originally estimated and the cost of
installing HC monitors on an estimated
20 devices (primarily cement kilns) that
will operate under the Tier II CO and
HC limits. The zero cost increase
associated with the PM emission
standard reflects the expectation that
BIFs complying with the metals
standards will achieve the O.08 gr/dscf
standard, and that most existing
industrial furnaces and some boilers are
already subject to this emission level (or
a more stringent level] as the result of
State Implementation Plans or New
Source Performance Standards. As a
result no incremental increase for
compliance with the PM emission limit
is projected
Tha additional costs for interim status
compliance reflects the increase in
annualized costs (over a 10 year period)
for preparation of the precompliance
and compliance certification packages
(including compliance testing) by
approximately 150 BIFs. The additional
cost for the CU standard is based on the
incremental cost of analysis for Cli
beyond that already required to
determined HC1 emissions.
The increase in annual recordkeeping.
sampling, and analysis costs reflects a
reassessment of the estimated costs in
the 1986 analysis. These increased costs
reflect a before-tax increase of
approximately $2.4 million for
recocdkeeping anH S0£ million for
sampling and analysis.
The impact of the 1986 tax code
changes was to reduce the p»atyn«l tax
rate imposed on before-tax profits and.
thus, has the affect of increasing the
impact of compliance costs oa afteMax
profits. As a result the change in the
1986 tax coda is to increase the after-tax
cost of the regulations by an estimated
$0.6 million per year. The increase in
costs due to inflation reflects an
estimated increase in compliance cost of
20 percent between the time of the
initial analysis (based on 1985 dollars)
and 1990.

(6) Measuring paramenters and
establishing limits based on trial bum
data—{1} General requirements. As
specified in paragraphs (e)(2) through
(e)(5) of mis section, each operating
parameter shall be measured, and
permit limits on the parameter shall be
established, according to either of the
following procedures:
(A) Instantaneous limits. A parameter
may be measured and recorded on an
instantaneous basis (i.e., the value that
occurs at any time) and the permit limit
specified as the time-weighted average
during all valid runs of the trial burn; or
(B) Hourly rolling average. (1) The
limit for a parameter may be established
and continuously monitored on an
hourly rolling average basis defined as
follows:
(i] A continuous monitor is one which
continuously samples the regulated
parameter without interruption, and
evaluates the detector response at least
once each 15 seconds, and computes
and records the average value at least
every 60 seconds.
(/i) An hourly rolling average is the
arithmetic means of the 60 most recent
1-minute average values recorded by the
continuous monitoring system.
(2) The permit limit for the parameter
shall be established based on trial bum
data as the average over all valid test
runs of the highest hourly rolling
average value for each run.
(ii) Rolling average limits for
carcinogenic metals and lead. Feed rate
limits for the carcinogenic metals (i.e,
arsenic, beryllium, cadmium and
chromium) and lead may be established
either on an hourly rolling average basis
as prescribed by paragraph (e)(6)(!) of
this section or on (up to) a 24 hour
rolling average basis. If the owner or
opeator elects to use an average period
from 2 to 24 hours:
(A) The feed rate of each metal shall
be limited at any time to ten times the
feed rate that would be allowed on an
hourly rolling average basis;
(B) The continuous monitor shall meet
the following specifications:
(1) A continuous monitor is one which
continuously samples the regulated
parameter without interruption, and
evaluates the detector response at least
once each 15 seconds, and computes
and records the average value at least
every 60 seconds.
(2) The rolling average for the selected
avenging period is defined as the
arithmetic mean of the most recent one
hour block average for the average
period. A one hour block average is the
arithmetic mean of the one minute
averages recorded during the 60-minnte
period beginning at one minute after the
beginning of preceding clock hour and
-------
7212 Federal Register / VoL 56. No. 35 / Thursday. February 21. 1991 / Rulei and Regulations
(C) The permit limit for the feed rate
of each metal shall be established based
on trial bum data as the average over all
valid test runs of the highest hourly
rolling average feed rate for each run.
(iii) Feed rate limits for metals, total
chloride and chlorine, and ash. Feed
rate limits for metals, total chlorine and
chloride, and ash are established and
monitored by knowing the concentration
of the substance (i.e., metals, chloride/
chlorine, and ash) in each feedstream
and the flow rate of the feedstream. To
monitor the feed rate of these
substances, the flow rate of each
feedstream must be monitored under the
continuous monitoring requirements of
paragraphs (e)(6) (i) and (ii) of this
section.
(Jv) Conduct of trial bum testing. (A)
If compliance with all applicable
emissions standards of §{ 266.104
through 266.107 is not demonstrated
simultaneously during a set of test runs,
the operating conditions of additional
teat runs required to demonstrate
compliance with remaining emissions
standards must be as close as possible
to the original operating conditions.
(B) Prior to obtaining test data for
purposes of demonstrating compliance
with the emissions standards of
{{ 266.104 through 266.107 or
establishing limits on operating
parameters under this section, the
facility must operate under trial bum
conditions for a sufficient period to
reach steady-state operations. The
Director may determine, however, that
industrial furnaces that recycle collected
participate matter back into the furnace
and that comply with an alternative
implementation approach for metals
under { 286.106(0. need not reach steady
state conditions with respect to the flow
of metals in the system prior to
beginning compliance testing for metals
emissions.
(C) Trial bum data on the level of an
operating parameter for which a limit
must be established in the permit must
be obtained during emissions sampling
for the pollutant(s) (i.e.. metals. PM.
HCl/Cls. organic compounds) for which
the parameter must be established as
specified by paragraph (e) of this
section.
(7) General requirements—{i) Fugitive
emissions. Fugitive emissions must be
controlled by:
(A) Keeping the combustion zone
totally sealed against fugitive emissions:
or
(B) Maintaining the combustion zone
pressure lower than atmospheric
pressure; or
(C) An alternate means of control
demonstrated (with part B of the permit
application) to provide fugitive
emissions control equivalent to
maintenance of combustion zone
pressure lower than atmospheric
pressure.
(ii) Automatic waste feed cutoff. A
boiler or industrial furnace must be
operated with a functioning system that
automatically cuts off the hazardous
waste feed when operating conditions
deviate from those established under
this section. The Director may limit the
number of cutoffs per an operating
period on a case-by-case basis. In
addition:
(A) The permit limit for (the indicator
of) minimum combustion chamber
temperature must be maintained while
hazardous waste or hazardous waste
residues remain in the combustion
chamber,
(B) Exhaust gases must be ducted to
the air pollution control system operated
in accordance with the permit
requirements while hazardous waste or
hazardous waste residues remain in the
combustion chamber and
(C) Operating parameters for which
permit limits an established must
continue to be monitored during the
cutoff, and the hazardous waste feed
shall not be restarted until the levels of
those parameters comply with the
permit limits. For parameters that may
be monitored on an instantaneous basis,
the Director will establish a minimum
period of time after a waste feed cutoff
during which the parameter must not
exceed the permit limit before the
hazardous waste feed may be restarted.
(Hi) Changes. A boiler or industrial
furnace must cease burning hazardous
waste when changes in combustion
properties, or feed rates of the
hazardous waste, other fuels, or
industrial furnace feedstocks, or
changes in the boiler or industrial
furnace design or operating conditions
deviate from the limits as specified in
the permit
(8) Monitoring and Inspections, (i) The
owner or operator must monitor and
record the following, at a minimum,
while burning hazardous waste:
(A) If specified by the permit feed
rates and composition of hazardous
waste, other fuels, and industrial
furnace feedstocks, and feed rates of
ash. metals, and total chloride and
chlorine;
(B) If specified by the permit carbon
monoxide (CO), hydrocarbons (HC), and
oxygen on a continuous basis at a
common point in the boiler or industrial
furnace downstream of the combustion
zone and prior to release of stack gases
to the atmosphere in accordance with
operating requirements specified in
paragraph (e)(2)(ii) of this section. CO,
HC. and oxygen monitors must be
installed, operated, and maintained in
accordance with methods specified in
appendix DC of this part.
(C) Upon the request of the Director.
sampling and analysis of the hazardous
waste (and other fuels and industrial
furnace feedstocks as appropriate),
residues, and exhaust emissions must be
conducted to verify that the operating
requirements established in the permit
achieve the applicable standards of
§§ 266.104.266.105.266.106, and 286.107.
(ii) All monitors shall record data in
units corresponding to the permit limit
unless otherwise specified in the permit
(iii>The boiler or industrial furnace
and associated equipment (pumps,
values, pipes, fuel storage tanks, etc.)
must be subjected to thorough visual
inspection when it contains hazardous
waste, at least daily for leaks, spills,
fugitive emissions, and signs of
tampering.
(iv) The automatic hazardous waste
feed cutoff system and associated
alarms must be tested at least once
every 7 days when hazardous waste Is
burned to verify operability, unless the*
applicant demonstrates to the Director
that weekly inspections will unduly
restrict or upset operations and that less
frequent inspections will be adequate.
At a minimum, operational testing must
be conducted at least once every 30
days.
(v) These monitoring and inspection
data must be recorded and the records
must be placed in the operating record
required by 1284.73 of this chapter.
(9) Direct transfer to the burner. If
hazardous waste is directly transferred
from • transport vehicle to a boiler or
industrial furnace without the use of a
storage unit the owner and operator
must comply with | 266.111.
(10) Recordkeeping. The owner or
operator must keep in the operating
record of the facility all information and
data required by this section for not less
than three years.
(11) Closure. At closure, the owner or
operator must remove all hazardous
waste and hazardous waste residues
(including, but not limited to. ash,
scrubber waters, and scrubber sludges)
from the boiler or industrial furnace.

the facility in the certification of
precompliance under paragraph (b) of
this section.
(iv) Determination of operating limits
based on all valid runs of the
compliance test for each applicable
parameter listed in paragraph (c)(l) of
i!iia section using either of the following
procedures:
(A) Instantaneous limits. A parameter
may be measured and recorded on an
instantaneous basis (i.e.. the value that
occurs at any time) and the operating
limit specified as the time-weighted
average during all runs of the
compliance test: or
(B) Hourly rolling average basis. (2)
The limit for a parameter may be
established and continuously monitored
on an hourly rolling average basis
defined as follows:
(/) ;•. continuous monitor is one which
continuously samples the regulated
parameter without interruption, and
evaluates the detector response at least
once each 15 seconds, and computes
und records the average value at least
every 60 seconds.
(if) An hourly rolling aveiage is the
arithmetic mean of the 60 most recent 1-
minute average values recorded by the
continuous monitoring system.
(2) The operating limit for the
parameter shall be established based on
compliance test data as the average
over ail test run* of the highest hourly
rolling average value for each run.
(C) Rolling average limits for
carcinogenic metals and lead. Feed rate
limits for the carcinogenic metals (i-e..
arsenic, beryllium, cadmium and
chromium) and lead may be established
cither on an hourly rolling average basis
as prescribed by paragraph (c)(4)(iv)(B)
of this section or on (up to)« 24 hour
rolling average basis, if the owner or
operator elects to use an averaging
period from 2 to 24 hours:
(/) The feed rate of each metal shall
be limited at any time to ten times the
feed rate that would be allowed on a
hourly rolling average basis:
p) The continuous monitor shall meet
the following specifications:
(/) A continuous monitor is one which
continuously samples the regulated
parameter without interruption, and
evaluates the detector response at least
once each 15 seconds, and computes
and records the average value at least
every 60 seconds.
(h] The rolling average for the
selected averaging period is defined as
the arithmetic mean of the most recent
one hour block averages for the
averaging period. A one hour block
average is the arithmetic mean of the
one minute averages recorded during the
60-minute period beginning at one
minute after the beginning of preceding
clock hour, and
[3) The operating limit for the feed
rate of each metal shall be established
based on compliance test data as the
average over all test runs of the highest
hourly rolling average feed rate for each
run.
(D) Feed rate limits for metals, total
chloride and chlorine, and ash. Feed
rate limits for metals, total chlorine and
chloride, and ash are established and
monitored by knowing the concentration
of the substance (i.e.. metals, chloride/
chlorine, and ash) in each feedstream
and the flow rate of the feedstream. To

fugitive emissions, and signs of
tampering.
(3) The automatic hazardous waste
feed cutoff system and associated
alarms must be tested at least once
every 7 days when hazardous waste is
burned to verify operability, unless the
owner or operator can demonstrate that
weekly inspections will unduly restrict
or upset operations and that less
frequent inspections will be adequate.
Support for such demonstration shall be
included in the operating record. At a

Budget under control number 2050-0073)
§266.104 Standards to control organic
(a) ORE standard—<1) General.
Except as provided in paragraph (a)(3)
of this section, a boiler or industrial
furnace burning hazardous waste must
achieve a destruction and removal
efficiency (ORE) of 99.99% for all organic
hazardous constituents in the waste
feed. To demonstrate confonnance with
this requirement 99.99% ORE must be
demonstrated during a trial bum for
each principal organic hazardous
constituent (POHC) designated (under
paragraph (a)(2) of this section) in its
permit for each waste feed. ORE is
determined for each POHC from the
following equation:
ORE:
[ i-Wtit
I w.
XlOO
where:
W „= Matt feed rate of one principal
organic hazardout constituent (POHC) in
the hazardous watte fired to the boiler or
industrial furnace: and
W ,*= Mass emission rate of the same
POHC present in ttack gas prior to
release to the atmosphere.
(2) Designation of POHCs. Principal
organic hazardous constituents (POHCs)
are those compounds for which
compliance with the ORE requirements
of this section shall be demonstrated in
a trial bum in confonnance with
procedures prescribed in { 270.66 of this
chapter. One or more POHCs shall be
designated by the Director for each
waste feed to be burned. POHCs shall
be designated based on the degree of
difficulty of destruction of the organic
constituents in the waste and on their
concentrations or mass in the waste
feed considering the results of waste
analyses submitted with part B of the
permit application. POHCs are most
likely to be selected from among those
compounds listed in part 261. appendix
VIH of this chapter that are also present
in the normal waste feed. However, if
the applicant demonstrates to the
Regional Administrator's satisfaction
that a compound not listed in appendix
Vffl or not present in the normal waste
feed is a suitable indicator of
compliance with the ORE requirements
of this section, that compound may be
designated as a POHC Such POHCs
need not be toxic or organic compounds.
(3) Dioxin-listed waste. A boiler or
industrial furnace burning hazardous
waste containing (or derived from) EPA
Hazardous Wastes Nos. F020. F021,
F022. F023, F026, or F027 must achieve a
destruction and removal efficiency
(DRE) of 99.9999% for each POHC
designated (under paragraph (a)(2) of
this section) in its permit This
performance must be demonstrated on
POHCs that are more difficult to bum
than tetrra-. penta-. and
hexachlorodibenzo-p-dioxins and
dibenzofurans. DRE is determined for
each POHC from the equation in
paragraph (a) of this section. In addition.
the owner or operator of the boiler or
industrial furnace must notify the
Director of intent to burn EPA
Hazardous Waste Nos. F020, F021. F022.
F023, F028. or F027.
(4) Automatic waiver of DRE trial
bum. Owners and operators of boilers
operated under the special operating
requirements provided by f 266.110 are
considered to be in compliance with the
DRE standard of paragraph (a)(l) of this
section and are exempt from the DRE*
trial bum.
(5) Low risk waste. Owners and
operators of boilers or industrial
furnaces that bum hazardous waste in
compliance with the requirements of
1266.109(a) an considered to be in
compliance with the DRE standard of !
paragraph (a)(l) of this section and an
exempt from the DRE trial burn.
(b) Carbon monoxide standard. (1)
Except as provided in paragraph (c) of
this section, the stack gas concentration
of carbon monoxide (CO) from a boiler
or industrial furnace burning hazardous
waste cannot exceed 100 ppmv on an
hourly rolling average basis (i.e.. over
any 60 minute period), continuously
corrected to 7 percent oxygen, dry gas
basis.
(2) CO and oxygen shall be
continuously monitored in confonnance
with "Performance Specifications for
Continuous Emission Monitoring of
Carbon Monoxide and Oxygen in
Hazardous Waste Incinerators. Boilers.

(3) Compliance with the 100 ppmv CO
limit must be demonstrated during the
trial bum (for new facilities or an
interim status facility applying for a
permit) or the compliance test (for
interim status facilities). To demonstrate
compliance, the highest hourly rolling
average CO level during any valid run of
the trial bum or compliance test must
not exceed 100 ppmv.
(c) Alternative carbon monoxide
standard. (1) The stack gas
concentration of carbon monoxide (CO)

(4) The alternative CO standard is
established based on CO data during
the trial burn (for a new facility) and the
compliance test (for an Interim status
lacility). The alternative CO standard is
ihe average over all valid runs of the
liighest hourly avenge CO level for each
tun. The CO limit is implemented on an
hourly rolling average basis, and
continuously corrected to 7 percent
(ixygen. dry gas basis.
(d) Special requirement* for furnaces.

Appendices IV and V of this part list the
acceptable ambient levels for purposes
of this rule. Reference air concentrations
(RACs) are listed for the
noncartinogenic metals and 10'* risk-
specific doses (RSDs) are listed for the
carcinogenic metals. The RSD for a
metal is the acceptable ambient level for

metal using the dilution factor for the
maximum annual average ground level
concentration predicted by dispersion
modeling in conformant with
paragraph (h) of this section: and

(A) Back-calculating from the RSD
provided in appendix V of this part to
determine the allowable emission rate
for each metal if that metal were the
only carcinogenic metal emitted using
the dilution factor for the maximum
annual average ground level
concentration predicted by dispersion
modeling in confonnance with
paragraph (h) of this section: and
(B) If more than ona carcinogenic
metal is emitted, selecting an emission
limit for each carcinogenic metal not to
exceed the emission rate determined by
paragraph (f)(2)(ii)(A) of this section
such that the sum for all carcinogenic
metals of the ratio of the selected
emission limit to the emission rate
determined by that paragraph does not
exceed 1.0.

efficiency. That is. assume that 0.1
percent of the mass weight of each
constitutent fed to the device is emitted.
(iii) For each constituent identified in
paragraph (a)(2)(i) of this section, use
emissions dispersion modeling to predict
the maximum annual average ground
level concentration of the constituent.

(1) Comparison of waste-derived
residue with normal residue. The waste*
derived residue must not contain
appendix VIII. part 261 constituents
(toxic constituents) that could
reasonably be attributable to the
hazardous waste at concentrations
significantly higher than in residue
generated without burning or processing
of hazardous waste, using th« following
procedure. Toxic compounds that could
reasonably be attributable to burning or
processing the hazardous waste
(constituents of concern) include toxic
constituents in the hazardous waste,
and the organic compounds listed in
appendix vm of this part that may be
generated as products of incomplete
combustion. Sampling and analyses
shall be in confonnance with procedures
prescribed in Tett Methods for
Evaluating Solid Waste. Physical/
Chemical Methods, incorporated by
reference in 1280.11(a) of this chapter.
(i) Normal residue. Concentrations of

about the mean of the concentration in
the normal residue shall be considered
-------
7228 Federal Register / Vol. 56, No. 35 / Thursday, February 21, 1991 / Rules and Regulations
the statistically-derived concentration in
the normal residue. If changes in raw
materials or fuels reduce the
statistically-derived concentrations of
the toxic constituents of concern in the
normal residue, the statistically-derived
concentrations must be revised or
statistically-derived concentrations of
toxic constituents in normal residue
must be established for a new mode of
operation with the new raw material or
fuel. To determine the upper 95%
confidence level about the mean of the
concentration in the normal residue, the
owner or operator shall use statistical
procedures prescribed in "Statistical
Methodology for Bevill Residue
Determinations" in appendix DC of this
part
(ii) Waste-derived residue.
Concentrations of toxic constituents of
concern in waste-derived residue shall
be determined based on analysis of
samples composited over a period of not
more than 24 hours. The concentration
of a toxic constituent in the waste-
derived residue is not considered to be
significantly higher than in the normal
residue if the concentration in the
waste-derived residue does not exceed
the concentration established for the
normal residue under paragraph (b)(l)(i)
of this section; or
(2) Comparison of waste-derived
residue concentrations with health-
based limits—(i) Nonmetcl constituents.
The concentrations of nonmetal toxic
constituents of concern (specified in
paragraph (b)(l) of this section) in the
waste-derived residue must not exceed
the health-based levels specified in
appendix VD of this part If a health-
based limit for a constituent of concern
is not listed in appendix VII of this part
then a limit of 0.002 micrograms per
kilogram or the level of detection (using
analytical procedures prescribed in SW-
846). whichever is higher, shall be used:
and
(li) Metal constituents. The
concentration of metals in an extract
obtained using the Toxicity
Characteristic Leaching Procedure of
S 261.24 of this chapter must not exceed
the levels specified in appendix Vn of
this part and
(c) Records sufficient to document
compliance with the provisions of this
section must be retained for a period of
three years. At a minimum, the following
shall be recorded:
(1) Levels of constituents in appendix
VTJL part 261. that are present in waste-
derived residues;
(2) If the waste-derived residue is
compared with normal residue under
paragraph (b)(l) of this section:
(i) The levels of constituents in
appendix VnL part 261, that are present
in normal residues; and
(ii) Data and information, including
analyses of samples as necessary,
obtained to determine if changes in raw
materials or fuels would reduce the
concentration of toxic constituents of
concern in the normal residue.

Removal of Strontium Sulfide from the
List of Hazardous Wastes; Technical Amendment
56 FR 7567-7568
February 25, 1991
(RCRA Cluster I, Non-HSWA Rule)
Note: 1) Because of an error in the amendatory language in the rule (53 FR 43881, October 31,
1988, Revision Checklist 57) removing strontium sulfide from the list of hazardous wastes, this
chemical was not removed from §261.33 or Part 261, Appendix VIII. This technical amendment
corrects that error by removing strontium sulfide from the two lists. States which have not
adopted the changes addressed by Revision Checklist 57, but intend to remove strontium sulfide
from their lists of hazardous waste, are strongly encouraged to adopt these technical amendments
at the same time the Revision Checklist 57 provisions are adopted. States already adopting the
Revision Checklist 57 changes are encouraged to ^adopt the Revision Checklist 86 amendments as
soon as possible.
2) This is a conditionally optional checklist. States choosing to not remove strontium sulfide
from their hazardous waste lists should not adopt the changes addressed by this present checklist.
However, those States which choose to remove this waste must adopt the changes addressed by
Revision Checklist 86 to assure that strontium sulfide has been properly removed from the State's
hazardous waste lists and appendices.

SUPPLEMENTARY INFORMATION: In tha
initial hazardous waste regulations
implementing section 3001 of RCRA, the
Agency listed as hazardous "emission
control dust/sludge from secondary lead
smelting" (EPA Hazacdaua Waste No.
K069). Thia totk« wee kotended to apply
to the lead-rich particdate captured by
secondary lead smelting air pollution
control devices utilized for control of
participate matter. See Background
Document for Listing of Hazardous
840-42. Thp iiieral language of the listing
regulation, however, encompasses not
only this lead-rich residue, but sludge*
captured by other types of air emission
control equsjKMit which sh*d*n arc
unlike the waste EPA intended to list hi
terms of physical form, vohime
generated, and toxiciry.

Extraction Procedure (EP): tm docket to
today's rule for biatnicai and recant
analytical data. To the Ageaoy'a
knowledge. Exide is the only secondary
lead smelter ihal generates this type of
slurry.
However, (he language of the JCD89
listing regulation captures the slurry
since it is a type of "sludge", i.e. a
reflMoe of a poasoon confrol process
(see | 26e.Mfl. The slurry is not the
waste the Agency meant to list. It ia not
generated by an air emission control
device used chiefly to control lead
emisaions and omvr particulace, it i* not
amenable to recovery in the secondary
lead process, it is not a dust, it ia
gozaated so lower volume* then the
typical KOS9 waata, and it contains
significantly tawer caacentrationa of
lead and other twbc aetala thaii the
typical K088 waate. Eidde prorided data
showing mat (he levels of lead (910
ppm) aitd cndainai (l£7 ppm) in irs
sledge are far below the level given m
the Agency's Background Document for
listing K069 (53,000 to 120,000 ppm lead.
aad 340 to 900 ppm cadmium).
Leachable concentrations of lead and
other toxic metals ia the starry are also
significantly less than in the usual K009
vrffste. Exide provided extensive
analytical data collected from 1989 to
1991 clearry demonstrating that
teachable levels ef toxic metals are low.
Specifically, approxunatery 100 EP
measurements of reachable metals taken
in 1989 show that cadmium, lead, and
chromium are asoally far below the
toxidty characteristic levels; the mean
EP value (at the 95th percentile upper
confidence limits) for these metals are
less than one tenth (i.e., 10-fold less
than) the characteristic levels. The
levels of leachment metals for typical
K069 wastes gjren to the Background
Document exceeded the characteristic
lerek by factors of 5 to 230 for
cadmram, 50 to 468 for lead, and 1 to 240
fordvouiiuuL Exide also provided more
recent TCLP measurements of its waste
obtained in 1996 and 19§1 that show
even longer teveb of reachable cadmium
and lead. Of nineteen TCLP samples, all
were less than one tenm of the
characteristic lerers. See the duuket to
today's rale for further details of this
analysis.
EPA inaenaa in fcaaear axtare to
propose to amend the language of the
K069 listing to clarify the scope of the
listing to excluded* sludges generated by
air pollution devices that are not a
plant's chief means of controlling tad
emissions. In the interim, however, the
Agency has determined tc great a
limited administrative stay of the KOCfl
listing pursuant to * U.S.C. 70S.1 in order
that the listing not apply to the slurry
waste generated by the Exide acid gu
scrubber or to any other similar waste
(if such • waata should oriaf). The
Agency Is taking tkia actoa aot onljr

199S2
Federal Register / Vol. 56, No. 84 / Wednesday, May 1. 1991 / Rules and Regulations
would not be listed if the Agency were
approaching the issue de novo, but also
because Exide is presently incurring
significant treatment and disposal costs
for this slurry (particularly as a result of
recently-promulgated treatment
standards issued as part of the Land
Disposal Restriction Third regulation, at
(55 FR 22568) (June 1.1990)) which
potentially jeopardize the company's
continued ability to operate. Given that
the listing appears to also apply
inappropriately to the waste, and other
lead-bearing materials, and that Exide's
recovery process specifically aids in
meeting the Land Disposal Restriction
treatment standards for lead acid
batteries, EPA finds that justice requires
issuance of a limited administrative
stay. See 5 U.S.C. 70S. For the same
reasons, EPA finds that grant of a stay is
necessary to prevent irreparable harm to
Exide, will not impede EPA's
administration of the subtitle C program
(which will continue to apply to all K069
wastes that EPA intended to list), and is
in the public interest
Accordingly, the Agency is issuing
this administrative stay of the K069
listing so that it does not apply to the
slurry generated by acid gas air
pollution control devices at Exide/
General Battery Reading, Pennsylvania
facility. The listing continues to apply to
Exide's (and. all other secondary lead
smelters') dusts generated by participate
matter air pollution control devices. The
administrative stay will remain in effect
until 30 day* after completing of
rulemaking dealing with the scope of the
K069 listing. If EPA takes further action
effecting this stay, EPA will publish a
notice of the action in the Federal
Register.

A. Background
On November 2,1990 (55 FR 46354)
the Environmental Protection Agency
(EPA) promulgated regulations under the
Resource Conservation and Recovery
Act (RCRA) adding two wastes to the
list of hazardous wastes under 40 CFR
261.31. Those wastes, designated as
F037 and F038, are generated in the
primary and secondary separation of
oil/ water/solids from petroleum
refinery process waste water and oily
cooling wastewaters.
Development of listings for sludges
generated in the primary and secondary
treatment of process wastewaters and
oily cooling wastewaters in the
petroleum refining industry has been a
long process, dating back ten years.
Prior to promulgation of the final
regulation, notices were published
regarding primary and secondary
treatment sludges on November 2,1980
(45 FR 74893). February 11.1985 (50 FR
5637), and April 13,1988 (53 FR 12182).
In the November 2,1990 final rule, the
preamble discussed the scope of the
listing and described those process and
oily cooling wastewaters generating the
listed waste (55 FR 46364). The preamble
indicated that "oily cooling waters" for
the purposes of the listing included
once-through cooling water from C. (six
carbon) hydrocarbons and heavier
operations. However, since publication
of the final rule, the Agency has teamed
that the inclusion of non-contact once-
through cooling water (as opposed to
once-through contact cooling water) in
the definition of oily cooling waters
unintentionally may extend the F037 and
F038 listings to wastes that are not
similar in constituent concentration to
others included in the listing. The
American Petroleum Institute (API)
provided data, which is included in the
docket for today's notice, that supports
the conclusion that sludges from non-
contact once-through cooling waters are
not similar to other primary and
secondary oil/water/solids separation
sludges generated at petroleum
refineries and should, therefore, be
excluded from the listings.
Consequently. EPA has determined that
sludges from once-through, non-contact
cooling water should not be listed and is
therefore today amending the listing
description.
In addition, the Agency today is
revising the definition of wastes subject
to the F038 listing for petroleum refinery
secondary (emulsified) oil/water/sou'ds
separation sludge, to clarify an
ambiguity in the listing description/The
revised language clarifies that b
sludges and floats generated in
aggressive biological treatment
defined in 40 CFR 261.31{b)(2)(i), and not
included in the F038 listing, are excluded
from the scope of that listing. It was not
EPA's intent to include those floats in
the F038 listing, and today's rule adds
language to clear up any confusion on
this issue.
B. Interim Final Rule
1. Non-Contact Once-Through Cooling
Water
Section 3001 of RCRA requires EPA to
list particular hazardous wastes that
must be subject to the RCRA hazardous
waste management system. Regulations
listing specified wastes must be based
on EPA-developed criteria codified at 40
CFR 261.11. The Hazardous and Solid
Waste Amendments of 1984 (HSWA),
among other provisions, added a new
secton 3001(e)(2) directing EPA to make
a determination whether or not to list as
hazardous a number of wastes.
including refinery wastes. In the
previously published notices, the
Agency explicitly discussed the
inclusion of cooling waters from C» and
heavier operations in the scope ofjhe
listings (see 53 FR 12164, April 12
However, the notice did not indl
that cooling water included non-cTJTTiac
once-through cooling water, which is
segregated wastewater used for cooling
that does not come in contact with oil.
Further, the Agency did not request
comment or data on the composition of
non-contact once-through cooling water
in any of the notices. Further, the cost of
managing such wastes was not analyzed
when EPA evaluated the regulatory
impact of the listings.
After publication of the final rule. EPA
received comments from the regulated
community contending that waste
produced in oil/water/solids separation
of non-contact once-through cooling
water is not similar in constituent
concentration to other wastes included
in the listing. As noted above, API
submitted data supporting their
contention that non-contact once-
through cooling water should not have
been included in the definition of oily
cooling waters.
The Agency's inclusion of once-
through cooling water from Ct (six
carbon) hydrocarbons and heavier
operations in the definition of oily
cooling waters was based on a 1969 API
petroleum refinery waste dispos
manual that was developed pric
implementation of current Clean^SJKer
Act (CWA) requirements. Discussion of
-------
Federal Register / Vol. 56, No. 92 / Monday, May 13. 1991 / Rale* and Regulation* 21957
liquid wMtM in the manual described
"once-through cooling water from
surface condensers and coolers handling
oil which will not vaporize rapidly on
exposure to air (Ct and heavier)" as one
t;/pe of oily cooling waters. The manual
indicated that such oily cooling waters
wen of concern because they can
can tain minor oil contamination from
sources such as spills or leaks in heat
exchange equipment. The manual made
a clear distinction between oily cooling
waters and oil-free cooling wastewaters,
such as once-through cooling water from
surface condensers and coolers which
normally handle gaseous products (Ct
a ad lighter).
In response to CWA requirements
rdated to surface water discharges that
were promulgated after publication of
the manual API contends that refineries
h we changed processes and adapted
their facilities to separate non-contact
once-through cooling water from other
wastewaters. Thus, these wastewaters
ai-e segregated from other oily
wastewaters. As a result sludges from
treatment of these wastewaters for the
most part contain metals (e.g.. arsenic.
n ckel. lead, and chromium) at much
lower levels than found in other primary
and secondary oil/water/solids
separation sludges. Further, the API
data indicate that the semivolatile
constituents of concern (e.g., benzene.
bi!nzo(a)pyrene, and chrysene), when
present are detected at levels at least
ICO times less than the average found in
olher wastes included in the F037 and
Fl)38 listings.
Based on the comments received by
the Agency after promulgation of the
November 2,1990 final rule. EPA has
concluded that wastes from the
separation of non-contact once-through
cooling water are significantly different
from the sludges the Agency intended to
lint as F037 and F038 and, thus, should
not be included in the scope of these
lintings. The Agency, however, is not
making a final listing determination on
these wastes and may, in the future,
evaluate sludges generated from non-
contact once-through cooling waters.
Today, the Agency is promulgating an
interim final rule that amends the listing
definitions for F037 and F038 to exclude
shdge generated from non-contact
once-through cooling waters that are
segregated for treatment from other
process or oily cooling wastewaters. It
should be noted that non-contact once-
through cooling waters that are mixed
with the wastewaters that will generate
the listed waste or with any other listed
hazardous waste become subject to
Subtitle C regulations under the mixture
rule (40 CFR 281.3(a)(2)(iv)). It also
should be noted that these wastewaters,
and any sludges generated from them,
could still exhibit one or more of the
characteristics of hazardous waste, and
if so. would be subject to appropriate
RCRA Subtitle C controls.
2. Floats Generated in Aggressive
Biological Treatment
The Agency also has learned that the
F038 listing description published in the
final rule on November 2.1990 could be
misinterpreted to include floats
generated during or after aggressive
biological treatment. Today's rule
further revises the F038 listing definition
to clarify that the F038 listing for
petroleum refinery secondary
(emulsified) oil/water/solids separation
does not include floats generated in or
downstream from aggressive biological
treatment units. EPA believes this was
clearly implicit in its discussion in the
final rule. The Agency spelled out in
detail what units were aggressive
biological treatment units in the
preamble to the final rule (see 55 FR
46358, November 2,1990) and
promulgated a detailed definition for
such units under 40 CFR 281.31(b)(2)(i).
The Agency believes its intent was plain
in both the preamble discussion and the
regulatory language. However, the
Agency agrees that some potential for
misinterpretation may exist and.
therefore, is clarifying the listing
description.
The Agency used the term "[a]ny
sludge and/or float" to describe the
listed F038 waste in the definition at 40
CFR 261.31 (55 FR 46396). This phrase
indicated the Agency's intent to regulate
all sludges and floats generated in the
physical and/or chemical separation of
oil/water/solids in process wastewaters
and oily cooling wastewaters. However,
the Agency used the term "sludges" to
describe the waste generated in an
aggressive biological treatment unit not
included in the listing. By failing to
include "and/or floats" the Agency did
not mean to suggest floats generated in
aggressive biological treatment unite
remained within the scope of the listing
as well However, because of the
potential for some confusion, the
Agency is amending the definition of
F038 specifically to exclude floats .
generated in aggressive biological
treatment unite from the F036 listing.
EPA today is soliciting comments on
its action today. In particular, the
Agency is seeking additional date that
would support or refute APTs contention
that non-contact once-through cooling
waters are substantially different from
other wastewaters included in the
definition of oily cooling waters, and
comment on the date the Agency has
received to date.
C. State Authority
1. Applicability of Rules in Authorized
States
Under Section 3006 of RCRA. EPA
may authorize qualified States to
administer and enforce the RCRA
program within the State. Following
authorization. EPA retains enforcement
authority under section 3006, 3013, and
7003 of RCRA. although authorized
States have primary enforcement
responsibility. The standards and
requirements for authorization are found
in 40 CFR part 271.
Prior to HSWA. a State with final
authorization administered its
hazardous waste program in lieu of EPA
administering the Federal program in
that State. The Federal requirements no
longer applied in the authorized State.
and EPA could not issue permits for any
facilities that the State was authorized
to permit When new. more stringent
Federal requirements were promulgated
or enacted, the State was obliged to
enact equivalent authority within
specified time frames. New Federal
requirements did not take effect in an
authorized State until the State adopted
the requirements as State law. In
contrast under RCRA section 3006(g) (42
U.S.C. 6926(g)), new requirements and
prohibitions imposed by HSWA take
effect in authorized States at the same
time that they take effect in
nonauthorized States. EPA is directed to
carry out these requirements and
prohibitions in authorized States.
including the issuance of permits, until
the State is granted authorization to do
so. While Steles must still adopt
HSWA-related provisions as State law
to retain final authorization, HSWA
applies in authorized States in the
interim. Consequently. In light of today's
revision. Table 1 in 40 CFR 271.l(j) also
has been amended. Table 1 identifies
Federal program requirements
promulgated pursuant to HSWA that are
effective regardless of a Stele's
authorization status.
2. Efftct on State Authorizations
EPA will implement the provisions of
today's interim final rule in authorized
States until their programs are modified
to adopt the final listings for primary
and secondary oil/water/solids
separation sludge and die modification
to the State's program is approved by
EPA. See discussion in the final rule at
55 FR 46381 (November 2,1990). In
nonauthorized Steles EPA will, of
-------
21958
Federal Register / Vol. 5«, No. 92 / Monday, May 13, 1991 / Roles and Regulations
course, implement the provisions of
today's rule.
As previously noted, the primary and
secondary oil/water/solids separation
sludge listings were promulgated
pursuant to a HSWA provision and must
be adopted by States that intend to
retain final authorization. However,
today's rule revises and narrows the
scope of the listing for primary and
secondary oil/water/solids separation
sludge from that of the final regulation
as promulgated. Today's interim final
rule (1) excludes non-contact, once-
through cooling water from the F037 and
F038 listings and (2) does not include
within the scope of the F038 listing floats
generated in or after aggressive
biological treatment units.
Consequently, such wastes are not
hazardous wastes for the purposes of
Federal regulation and regulation of
these wastes is not required. At the
same time, under section 3009 of RCRA,
States remain free to impose more
stringent requirements than those
imposed under Federal regulations. As a
result, States, as authorized by State
statute, may chose to regulate the
wastes from non-contact once-through
cooling wastes or aggressive biological
treatment units or may require other
more stringent conditions upon
management of these wastes.
D. CERCLA Designation and Reportable
Quantities
AH hazardous wastes listed in 40 CFR
261.31 through 281.33. as well as any
solid waste that meets one or more of
the characteristics of a RCRA hazardous
waste (as defined at 40 CFR 281.21
through 281.24). are hazardous
substances under the Comprehensive
Environmental Response,
Compensation, and Liability Act of 1980
(CERCLA), as amended, pursuant to
CERCLA section 101(14). Therefor*, the
waste streams that were listed as
hazardous waste in the November 2.
1990 rule (55 FR 46354) will, on the
effective date of the rule. May 2.1991,
automatically become hazardous
substances. CERCLA hazardous
substances are listed in Table 302.4 at 40
CFR 302.4 along with their reportable
quantities (RQs).
Under CERCLA section 103(a). the
person in charge of a vessel or facility
from which a hazardous substance has
been released in a quantity that equals
or exceeds its RQ shall immediately
notify the National Response Center of
the release. In addition to the reporting
requirements under CERCLA, section
304 of the Emergency Planning and
Community Right-to-Know Act of 1966
(EPCRA) requires owners or operators
of certain facilities to report the releases
of a CERCLA hazardous substance or
Extremely Hazardous Substance (EHS)
to State and local authorities. EPCRA
Section 304 notification must be given
immediately after the release of an EHS
in the amount of an RQ or more to the
community emergency coordinator for
each local emergency planning
committee (LEPC) for an area likely to
be affected by the release, and to the
State emergency planning commission
of any State likely to be affected by the
release.
With the revision of the definitions of
waste subject to the F037 and F038
listings, as discussed previously hi
today's notice, the Agency is revising
the F037 and F038 listings in 40 CFR
302.4 and the codified list of CERCLA
hazardous substances.
Under Section 102(b) of CERCLA. all
hazardous wastes newly designated
under RCRA will have a statutory RQ of
one pound unless and until the RQ is
adjusted by regulation under CERCLA.
The November 2.1990 rule provided that
the RQ for the newly added FD37 and
F038 wastes would be one pound until
revised under a CERCLA rulemoking.
On March 27.1991. the Agency
published a separate rulemaking under
CERCLA (55 FR 12826), which proposed
to adjust the RQ for these wastes at one
pound. The changes in today's rule do
not change the proposed RQs.
E. Regulatory Requirements
1. Regulatory Impact Analysis
Under Executive Order 12291, EPA
must determine whether a regulation is
"major" and therefore subject to the
requirements of a Regulatory Impact
Analysis. The overall effect of today's
rule is to narrow the definition of those
wastes subject to the F037 and F038
hazardous waste listings for petroleum
refinery primary and secondary oil/
water/solids separation sludge. The net
effect of this proposal is to extend cost
savings to the regulated community.
Consequently, no regulatory impact
analysis is required.
2. Regulatory Flexibility Act
Pursuant to the Regulatory Flexibility
Act 5 U.S.C. 601-612. whenever an
agency is required to publish a General
Notice of Rulemaking for any proposed
or final rule, it must prepare and make
available for public comment a
regulatory flexibility analysis that
describes the impact of the rule on small
entities (i.e., small businesses, small
organizations, and small governmental
jurisdictions). No regulatory flexibility
analysis is required, however, if the
head of the Agency certifies that die rule
will not have a significant tmpactj
substantial number of small enr
The narrowing of the defuiitic

refinery primary and secondary oil/
water/solids separation sludge (F037
and F038) promulgated today is
deregulatory in nature and thus will
only provide beneficial opportunities for
entities that may be affected by the rule.
Accordingly, I hereby certify that this
regulation will not have a significant
economic impact on a substantial
number of small entities. This
regulation, therefore, does not require a
regulatory flexibility analysis.
3. Paperwork Reduction Act
There are no reporting, notification, or
recordkeeping (information) provision in
this rule. Such provisions, were they
included, would be submitted for
approval to the Office of Management
and Budget (OMB) under the Paperwork
Reduction Act 44 U.S.C 3501 et sea.

SumiMlNTARY INFORMATION: Snapper-
grouper species, including wreckfiah, are
managed under the FMP, prepared by
the South Atlantic Fishery Management
Council (Council), and its Implementing
regulations at 50 CFR part 648, under the
authority of the Magnuaon Fishery
Conservation and Management Act
(Magnuson Act).
In accordance with procedure*
approved in Amendment 3 to the FMP,
the Council recommended and NOAA
published a proposed rule changing the
wreckfish annual quota (56 FR 14496,
April 10.1991). That notice (1) described
the framework procedure of the FMP
through which the Council
recommended the change; (2) specified
the change; and (3) described the need
and rationale for the change. Those
descriptions and specification* are not
repeated here. No comments were
received on the proposed rule.
The Regional Director, Southeast
Region. NMFS, concurs that tha
Council's recommended wreckfiah quota
i* necessary to protect the resource aad
finds that it is consistent with the goal*
and objectives of the FMP. In addition,
NOAA finds that it is consistent with
the Magnuson Act and other applicable
law. Accordingly, the Council's
recommended wreckfish quota is
implemented for the fishing year mat
commenced April 16.1991.
Because this change in quota ts for a
fishing year that ha* already
commenced the Assistant
Administrator for Fisheries. NOAA.
finds for good catue, namely, to provide
effective conservation and management
of the wreckfiah resource, that it is
impracticable and contrary to the public
interest to delay for 30 days the effective
date of this rule under the provisions of
section 563(d)(3) of the Administrative
Procedure Act

Final Regulatory Determination for
Special Wastea From Mineral
Processing (Mining Waste Exclusion)
AGENCY: Environmental Protection
Agency.
ACTION: Final regulatory determination
and final rule.
SUMMARY: Today's action presents the
Agency's final regulatory determination
required by section 3001(b)(3)(C) of the
Resource Conservation and Recovery
Act (RCRA) for 20 special wastes from
the processing of ores and minerals.
EPA has concluded that regulation
under Subtitle C of RCRA is
inappropriate for alt 20 of the special
wastes that were studied. EPA plans to
address 18 of the wastes under subtitle
0. possibly in the program being
developed for mining wastes. For the
remaining two wastes (phosphogypsum
and process waste water from
phosphoric acid production), EPA plans
to proceed with the development and
promulgation of a program under the
Toxic Substances Control Act (TSCA)
that will address their management,
including possible regulations
concerning waste minimization/
pollution prevention for these wastes. In
addition, EPA plans to use existing-
authorities under either RCRA Section
7003 or CERCLA section 106 to address
any site-specific ground-water
contamination problems that are
believed to pose substantial and
imminent endangerment to human-
health or the environment. EPA has also
decided to postpone consideration of a
possible ban on the utilization of one of
the special wastes, slag from elemental
phosphorus production in construction
and/or land reclamation.
The rationale and salient facts used
by the Agency to arrive at these
decisions are provided below.

I. Background
A. Statutory Authority
Today's notice is issued under the
authority of section 3001(b)(3)(C) of
RCRA. which requires that after
completion of the Report to Piaiflroeii
mandated by section 8002(p) of RCRA.
the Administrator must determine
whether or not subtitle C regulation of
the special study wastes is warranted.
Wastes for which the exclusion it*
retained will continue to be subject to
regulation under RCRA Subtitle D as
solid wastes.
B. History of the Mining Waste
Exclusion
In October, 1980, RCRA was amended
by adding section 3001(b)(3)(A){H) to
exclude "solid waste from the
extraction, beneficiation, and processing
of ores and minerals" from regulation a*
hazardous waste under subtitle Cof
RCRA, pending completion of a study
and a Report to Congress required by
section 8002 (f) and (p) and a
determination by the EPA Administrator
either to promulgate regulations ander
subtitle C or that such regulation! err
enwarranted and that the exclusion
should continue (as required by suction
3001(bH3)(C}). EPA modified its
hazardous waste regulations in
November 1980 to reflect this "Mining
Waste Exclusion," and issued a
preliminary, and quite broad,
interpretation of the scope of its
coverage. In particular. EPA interpreted
the exclusion to include "solid waste
from the exploration, mining, miffing,
smelting and refining of ores and
minerals" (45 FR 78618, November 1ft,
1980).
In 1984. EPA was sued for failing to
submit the Report to Congress and make
the required regulatory determinatkm.br
the statutory deadline (Concerned •
Citizens ofAdamstown v. EPA No. 84-
3041. D.D.O, August 21.1985). In
responding to this lawsuit, the
explained that it planned to propose a
narrower interpretation of the scope of
the Mining Waste Exclusion, so that it
would encompass fewer wastes, and,
nsoposed to the Court two schedules^
One for completing the section 8002
studies of extraction and beneficiation
wastes and submitting the Report to
Congress addressing these wastes, and
one for proposing and promulgating a
reinterpretation for mineral processing
wastes. In so doing, the Agency, in
effect, split the wastes that might be
eligible for exclusion from regulation
into two groups: Mining (mineral
extraction and beneficiation) wastes.
and mineral processing wastes. The
Court agreed to this approach and
established a schedule for the two tasks.
On December 31.1985. EPA published
the required Report to Congress on solid
wastes from mineral extraction and
beneficiation, and on July 3,1988 (51 FR
24498) published a determination that
regulation of such wastes under subtitle
C of RCRA was not warranted. Since
the determination was made, the
Agency has been developing a tailored
regulatory approach for these wastes
under RCRA subtitle 0.
In keeping with its Court-ordered
dkective to reinterpret the Mining
Waste Exclusion for mineral processing
wastes, in October, 1985, EPA proposed
to narrow the scope of the Exclusion
mineral processing wastes to incluc
only a few specific waste streams I
BO FR 40292, October 2,1985). However.
the Agnacy did not specify the criteria
that it used to identify these wastes, or
to distinguish them from other wastes
that were not identified as being eligible
for the exclusion. In response to this ,
proposal, many companies and industry
organizations "nominated" wastes that
they believed were eligible for the
regulatory exemption. Faced with an
inability at that time to articulate
criteria that could be used to distinguish
exempt from non-exempt wastes and the
approaching Court-ordered deadline for
Gnat action. EPA withdrew its proposal
on October 9.1988 (51 FR 36233).
In July, 1988, the court in
Bnrifonnental Defense Fund v. EPA.
862 PJd 1318 (D. C. Cir. 1988). cert.
denied, 109 S. Ct. 1120 (1989) held that
EPA's withdrawal of its 1985 proposal
was arbitrary and capricious, and
ordered EPA to reinterpret the scope 01
the Exclusion for mineral processing
wastes. In particular. EPA was directed
by the court to restrict the scope of the
Exclusion as it applied to mineral
processing wastes to include only "lnrge
wjlume. low hazard" wastes. In a series
of rmusnaking notices. EPA has. c
the past three years, established
-------
Federal Regbter / Vol 5ft Na> 114 / Thuraday. June 13. 1901 / Rute» *ad Regulations 27381
boundaries of the Mining Waste
Exclusion for mineral processing wastes.
hat articulated the criteria that were
used to define "mineral processing," and
haa evaluated whether individual
wastes are large volume and low hazard
and, thus, eligible for the temporary
exclusion provided by RCRA section
3001(b)(3)(A)(iJ). This rulemaking
process was completed with the
publication of final rules on September
1.1989 (54 FR 36592) and January 23.
1990 (55 FR 2322). With the completion
of these notices, the Agency established
that the temporary exemption from
subtitle C requirements established by
the Exclusion for mineral processing
wastes and. therefore, the scope of the
Report to Congress, was limited to 20
specific mineral processing wastes.
EPA then prepared and submitted a
detailed and comprehensive Report to
Congress addressing the 20 special
mineral processing wastes, in
compliance with the Court-ordered
deadline. In addition to the explicit
consideration of the eight study factors
listed at section 8002(p) of RCRA, the
Agency included in the Report a
proposed regulatory status for each of
the 20 special wastes. Thus, the Report
serves both as an information source
and as a tentative indication of the
Agency's final determination.
Accordingly, and In compliance with
statutory directive, the Report.the data
and analyse* that underlie it and the
comments received on it have served as
the primary basis for the regulatory
decisions that are articulated in today's
notice.
EPA did not complete the regulatory
determination within the six month
statutory deadline. As a result the
Environmental Defense Fund Bled a new
RCRA citizen's suit which was settled
by consent decree. EOF v. EPA. No. fl-
0429 (D.D.C Mar. 4.1991). Under the

2. Study Factors
The RTC addressed the following
eight study factors isquired by section
8002(p) of RCRA:
1. The) sources and volume* of such
materials generated per yean
2. Preaent disposal and utilization
practices:
3. Potential danger to human heahb
and the environment from the disposal
and reuse of such materials;
4. Documented cases in which danger
to human health or the environment ha»
been proved;
5. Alternatives to current disposal
methods:
8. The costs of such alternatives;
7. The impacts of these alternative* on
the use of phosphate rock, uranhm on.
and other natural resource*; and
6\ The current and potential utilization
of such material*.
In addition, the statute suggests that
the Administrator may review studies
and other actions of other federal and
state agencies, and invite participation
by other concerned parties, including
industry and other federal and state
agencies, with a view toward avoiding
duplication of effort
The Agency's approach in preparing
this Report was to combine certain
study factors, for purposes of analysis
and exposition, into seven sections. The
first section provides a brief overview of
the industry, including the types of
production processes used and the
number and location of operating
facilities that generate one or more of
the mineral processing special wastes.
The second section summarizes
information on waste characteristics.

a. Approach 1: Application of the RCRA
Section 8002(p) Study Factors
1. Wastes EPA Tentatively
Recommended to Remain Under RCRA
Subtitle D
Using the study factors listed in RCRA
section 8002(p), EPA examined: (1) The
potential for and documented danger to
human health and the environment; (2)
the need for additional regulations; and
(3) the costs and impacts of subtitle C
regulation for the 20 special wastes.
EPA's analysis did not merely evaluate
whether the wastes should be treated as
hazardous in light of the criteria under
subtitle C for other wastes, but took into
account Congress' desire to examine
"special wastes" in a different light
EPA's analysis suggested that regulation
under subtitle C of RCRA would be
inappropriate for the following 16
mineral processing wastes:
• Red and brown muds from bauxite
refining:
• Treated residue from roasting/
leaching of chrome ore;
• Gasifier ash from coal gasification;
• Process wastewater from coal
gasification:
• Slag from primary copper
processing:
• Slag tailings from primary copper
processing;
• Slag from elemental phosphorus
production;
• Iron blast furnace slag;
• Basic oxygen furnace and open
hearth furnace slag from carbon steel
production;
• Air pollution control dust/sludge
from iron blast furnaces;
• Air pollution control dust/sludge
from basic oxygen furnaces and open
hearth furnaces from carbon steel
production;
• Huorogypsum from hydrofluoric
acid production;
• Process wastewater from primary
magnesium processing by the anhydrous
process;
• Process wastewater from
phosphoric acid production;
• Phosphogypsum from phosphoric
acid production; and
• Slag from primary zinc processing.
Three of these sixteen wastes (treated
residue from roasting/leaching of
chrome ore: process wastewater from
coal gasification: and slag tailings from
primary copper processing) were found
not to pose an actual or potential danger
to human health and the environment
The thirteen remaining wastes were
identified as having some actual or
potential hazard associated with current
management practices or plausible
mismanagement scenarios, and so were
further evaluated.
EPA found that the potential risk
associated with slag from primary zinc
processing, process wastewater from
primary magnesium processing by the
anhydrous process, air pollution control
(APC) dust/sludge from iron blast
furnaces and from basic oxygen and
open hearth furnaces used to make
carbon steel, red and brown muds from
bauxite refining, elemental phosphorus
slag, and gasifier ash from coal
gasification, was comparatively low;
that is, the Agency found that
management of these materials did not
present a substantial hazard to human
health or the environment. In particular.
no documented damages attributaJ^B|
these wastes were identified. In V^p
addition. State regulations are in effect
for the one primary magnesium facility
and revised/strengthened regulations
have been proposed for the primary zinc
processing facility. EPA also found that
several facilities recycle rather than
dispose of ferrous metal production APC
dust Therefore, the Agency found that
subtitle C regulation was not
appropriate. In the case of elemental
phosphorus slag, the Agency found that
while there appeared to be some
significant hazards associated with use
of the material in construction
applications (that is, off-site utilization).
the best means of dealing with this
problem was through the use of
authorities provided by RCRA section
3001(b)(3)(B)(iii) (which allows for
special controls from phosphate rock
mining and mineral processing wastes)
rather than through imposition of the
subtitle C hazardous waste management
standards.
EPA identified four wastes that did
not exhibit a hazardous characteristic
(with the exception of one sample of
copper slag at one facility) but for which
documented cases of adverse
environmental impacts that af
surface water were identified at
one facility:
-------
Federal Register / Voh 5ft No. 114 / Thursday. |uac 13. 19» f Rules and Regulations 27S03
• Iron blast furnace slag;
• Slag from primary copper
processing;
• Basic oxygen furnace and open
hearth furnace slag from carbon steel
production: and
• Fluorogypsum from hydrofluoric
acid production.
For ad four wastes, however, these
surface water releases (one of which
occurred via ground water) have been .
and/or are being addressed under
existing regulatory authorities at the
state and/or federal level Therefore, the
Agency concluded that regulation of
these four wastes as hazardous would
not provide additional protection to
human health or the environment
justifying the elimination of the special
status of these wastes; thus, subtitle C
regulation wat not considered
appropriate.
Pbosphogypsum and phosphoric acid
process wastewater were also of
concern because damage case
information Indicated that both closed
and currently active phosphogypsum
stacks (in which both the
phosphogypsum and the wastewater are
managed) and wastewater cooling
ponds have caused ground-water
contamination at IS of the 16 facilities
for which monitoring data are available.
The available waste composition data
indicated that phosphogypsum tested EP
toxic at one of the ten facilities with
available data, and process wastewater
exhibited the characteristic of
corrosivity at most facilities and the EP-
toxiciry characteristic at some facilities.
However. EPA also estimated that the
total industry-wide, incremental
annualized cost of either full subtitle C
regulation or the Subtitle C-Minus
scenario " for phosphogypsum and
process wastewater. as compared to the
Subtitle D-Plus scenario * developed for
cost estimating purposes, could exceed
$500 million and $50 million
respectively, and could significantly
affect several facilities. The Report
estimated that economic impacts
associated with subtitle C or C-Minus
regulation at these facilities were
expected to be significant and it was
unlikely that these facilities could pas*
along their higher costs. As a result EPA
tentatively concluded that regulation for
these wastes was most appropriate
under RCRA subtitle D.

2. Wastes EPA Tentatively Considered
for Regulation Under RCRA Subtitle C
orD
EPA found, based on the information
available at that time, that the remaining
four wastes (calcium suifate wastewater
treatment plant shidge from primary
copper processing, slag from primary
lead processing, process wastewater
from hydrofluoric acid production, and
chloride process waste solids from
titanium tetrachloride production) have
posed or may pose a danger to human
health or the environment. Available
data indicated that all four of the wastes
exhibit one or more of the
characteristics of hazardous wastes. In
particular. EPA found that all of the
wastes except process wastewater from
hydrofluoric acid production exhibit the
characteristic of EP toxiciry at at least
one facility; process wastewater from
hydrofluoric acid production was found
to be corrosive at all facilities where rt
is generated. In addition, damages
associated with these wastes were
documented as follows: (1) Current lead
slag management practices have
resulted in surface water contamination:
(2) ground-water contamination that
may in part be attributable to calcium
suifate sludge from primary copper
processing was found at one of the two
facilities that generate the waste; and (3)
ground-water contamination that may in
part be attributable to chloride process
waste solids from titanium tetrachloride
production was identified at at least one
facility that generates this waste.
Furthermore, the Report stated that the
Agency was not confident that current
practices and regulations are adequate
to prevent further danger to health or
the environment from these four wastes.
Nevertheless. EPA tentatively
concluded that regulation of three of the
four wastes as hazardous (calcium
suifate wastewater treatment plant
sludge from primary copper processing,
slag from primary lead processing, and
chloride process waste solids from
titanium tetrachloride production).
under full subtitle C was not appropriate
due to cost considerations. The
Agency's basis for this finding was a
cost comparison between full subtitle C
and the D-Plus scenario (with Subtitle
D-Plus including subtitle D requirements
similar to those being developed for
extraction and beneficiation wastes)
that snowed that the coats for fid)
subtitle C regulation would be
significantly higher and the associated
impacts would be more significant at
nearly all facilities than the estimated
costs of regulation under the Subtitle D-
Plus scenario.
For process wastewatw from
hydrofluoric acid production. EPA found
that the estimated compliance costs for
regulation under rail subtitle C and
regulation under die Subtitle D-Plus
scenario were comparable and that the
likely economic impacts were not
expected to be significant Based on
these factors, EPA tentatively concluded
that process wastewater from
hydrofluoric acid production may
warrant regulation under subtitle C.
On the other hand, EPA also
estimated the cost of managing these
four wastes under a subtitle C scenario
that utilizes the flexibility provided by
RCRA section 3004(x) (Subtitle C-
Minus).* The Agency then compared die
costs for Subtitle C-Minus regulation
(rather than full subtitle C regulation) to
the estimated costs that might result
from regulation under a subtitle 0
program similar to those being
developed for extraction and
beneficiation wastes (Subtitle D-Plus).
EPA found that the estimated costs for
the Subtitle C-Mirms and Subtitle D-Plus
scenarios are comparable for nearly all
facilities. Assuming a Subtitle C-Minus
scenario, EPA tentatively concluded 'hat
all four wastes might warrant regulation
under subtitle C
b. Approach £• Application of the RCRA

Additional ConaJderatiom
Sections 3001(b)(3) and 8002(p) of
RCRA and the decision in
Environmental Defense Fundv. EPA.
852 P.2d 1909 (D.C. Clr. 1988) make it
clear that the Agency may and should
consider the specific factors of section
8002(p) (1MB) in making its decision
regarding the appropriate regulatory
status of special wastes. In addition, the
Agency stated In the Report that in
making its regulatory determination, it
might be appropriate to consider other
factors relating to the broader goals and
objectives of the Agency and RCRA.
such as developing and maintaining
strong stale mining and mineral
processing waste regulatory programs
and facilitating implementation of
federal programs.
Accordingly. EPA stated in the Report
to Congress that In order to facilitate
both development and maintenance of
strong state programs and
implementation of any federal
regulations that may be necessary for
mineral processing wastes. It slight be

appropriate to regulate all 20 of the
special wastes under subtitle D of
RCRA. In addition, the Report stated
that some mining and mineral
processing wastes might be excluded
from any further federal regulation
under RCRA.
In light of these considerations, the
results of Approach 2 indicated that it
might be appropriate for the waste
streams identified under Approach 1 for
potential subtitle C (full C or C-Minus)
regulation not be subject to the
hazardous waste management
standards, but instead to be retained
within the Mining Waste Exclusion. If
such a finding was appropriate. EPA
stated that it would need to be
conditioned on the premise that major
steps be taken to control releases from
the facilities generating these waste
streams. Some corrective measures are
already being taken under a variety of
Agency authorities (e.g., RCRA,
Superrund, CWA) and more can and
would be undertaken. EPA also asserted
that the states must act to address the
most immediate problems posed by
these wastes, as well as any of the other
mineral processing special wastes that
have been found in the Report to pose
significant actual or potential hazard to
human health or the environment. To
assist in this effort. EPA pledged to
provide technical and other resource
support to the involved states to
improve their programs. If near term
actions did not result in adequate
control of such wastes, EPA would then
take action to reconsider its regulatory
determination and could designate
certain waste streams as subtitle C
hazardous wastes.
4. Public Comment Process
With publication of the Report to
Congress, EPA initially established a 60-
day public comment period that ended
on September 28,1990. In response to
requests from several commenters.
however, EPA extended the comment
period to October 19.1990. In addition. •
public hearing on the Report was held in
Washington. OC on October 17.1990.
EPA received 91 sett of written
comments prior to the close of the
comment period and eight late
comments. All individual comments and
a transcript from the public hearing are
available for public inspection in the
docket (Docket No. F-90-RMPA-FFFFF).
The docket also contains a summary of
all the comments presented at the
hearings or submitted in writing. EPA's
responses to those comments are
provided in the docket as well as in
appendix A to this regulatory
determination.
D. Supplemental Analysis and Notice of
Data Availability
Supplemental analyses were
conducted on five wastes that were
addressed in the Report to Congress,
including gasifier ash and process
wastewater from coal gasification, basic
oxygen furnace and open hearth furnace
air pollution control dust/sludge, and
phosphogypsum and process
wastewater from phosphoric acid
production. A Notice of Data
Availability (NODA). which announced
the availability of this information, was
published in the Federal Register on
January 7,1991.
A 30-day public comment period was
provided, which closed on February 6,
1991. As in the case of the Report to
Congress, EPA received requests that it
extend the comment period. However,
EPA did not extend this comment period
because of the need to proceed with the
regulatory determination process at
expeditiously as possible and because
the Agency believed that the comment
period provided was adequate. In
addition. EPA took steps to ensure that
commenters could make the maximum
use of the time available. For example.
EPA made the supplemental data
publicly available as soon as possible.
immediately following Agency
signature, rather than waiting until the
NODA was published in the Federal
Register. Also, at the request of industry,
EPA delayed the start of the public
comment period until after the holidays.
Included in the new data was
information on phosphoric acid process
wastewater and phosphogypsum
concerning generation and management
of these wastes, the engineering
feasibility and cost of alternative waste
management practices, waste
characteristics, ground water monitoring
data, and state regulations. The Agency
specifically solicited comments on the
engineering feasibility and accuracy of
cost estimates for the alternative waste
management practices presented as part
of the new data.
The Agency received 22 written
comments addressing the NODA. All of
the comments are available for public
inspection in Docket No. F-91-RM2A-
FFFFF. Agency responses to the
comments are provided in the docket
and appendix B to this regulatory
determination.
II. Factors Considered in Making tha
Regulatory Determination
The RCRA statute, as amended,
directs EPA to make a regulatory
determination for the special study
wastes based upon its Report to
Congress and comments received from
interested parties. The statute contains
the following eight study factors:
1. The sources and volumes of s|
materials generated per year
2. Present disposal and utilization
practices;
3. Potential danger, if any, to human
health and the environment from
disposal and reuse of such materials;
4. Documented cases in which danger
to human health or the environment has
been proved;
5. Alternatives to current disposal
methods;
6. The costs of such alternatives;
7. The impact of those alternatives on
the use of phosphate rock and uranium
ore, and other natural resources; and
8. The current and potential utilization
of such materials.
In addition. RCRA section 8002(p)
suggests that EPA review studies and
actions of other federal and state
agencies, and invite participation from
concerned parties, including industry
and other federal and state agencies in
an attempt to avoid duplication of effort.
EPA has complied with the
Congressional mandate in developing
the required Report to Congress and
soliciting and incorporating comments
received from affected parties. In
making today's regulatory
determination, the Agency has ;
upon the analysis of the eight stu|
factors described as "Approach 1'TTTthe
RTC, modified slightly in response to
public comments. EPA believes that this
approach is most consistent with
Congressional intent. To the extent that
the Agency were otherwise to conclude
that subtitle C regulation was warranted

factors and information. EPA believes.

already embodied within the contours of
the inquiry that Congress intended for
EPA to make in the Report and
regulatory determination. The Report
identifies (1) the development and
maintenance of strong state mining and
mineral processing regulatory programs.

federal mining regulatory progranus. the

Section 8002(p)(5) instructs EPA l

disposal methods" at a factor in
developing the Report and regulatory
determination. Certainly, consideration
of alternative state regulatory schemes,
in addition to federal schemes, is
contemplated by this section. Also,
facilitation of a potential integrated
federal mining program was actually
considered by EPA in its cost estimates
(reflected in the "Subtitle D-Plus
scenario").
Nonetheless, EPA does not believe
that it should rely on "possible"
improved state programs to determine
that subtitle C is not warranted unless
EPA is confident that such programs are
being developed and can address the
problems associated with mineral
processing wastes that may pose a
significant risk. Thus, EPA believes that
section 8002(p) requires that EPA not
consider these factors in a way that
would supplant any decision the Agency
makes under the decision making
methodology outlined in Approach 1.
In any event. EPA notes that the issue
is effectively moot As discussed below.
EPA has determined, on the basis of
Approach 1. that subtitle C is not
appropriate for any of the 20 wastes
analyzed. Thus, even if EPA were to
employ Approach 2 as outlined in the
Report it would not change any of the
decisions made today.
In "Approach 1," the Agency
evaluated the RCRA section 8002(p)
study factors by first assessing the need
for additional regulatory controls (or
absence thereof), then evaluating the
options for appropriate requirements
that could be applied to each Individual
waste stream for which additional
controls might be in order, and. finally,
estimating the associated costs and
impacts. In applying the decision
criteria, EPA believes that the factors
that are most important in establishing
the regulatory status of the special
wastes should be given major emphasis.
Therefore, potential risks posed and
documented damages caused by the
wastes, the need for additional
regulations, and the costs and impacts
that would be associated with more
stringent regulatory controls are the
focus of the three steps in the analytical
process. The reason for this is that in the
absence of a realistic showing of a
potential risk and/or documented
damages from current management (or
in appropriate cases, plausible
mismanagement), EPA believes that
Congress would not intend to eliminate
the special status of these wastes by
imposing hazardous waste regulation
under RCRA Subtitle C; if greater
regulatory controls may be appropriate
because of significant potential or
documented danger, the costs and
impacts of regulatory controls are the
critical factors in determining whether a
given alternative would conform to
Congress' expressed goals for these
wastes (adequate protection of human
health and the environment and
continued operation of the affected
industries).
The overall decision making process
as described in the RTC was left
basically intact for the purpose of this
regulatory determination. However, a
number of specific changes have been
made to the individual decision criteria
in response to public comments; these
changes are detailed below, and address
the specific questions considered in this
step-wise process, as well as how the
answers to these questions interact
when deciding whether to go from one
step to the next
The modified step-wise process that
the Agency applied to the available
information is outlined below.
Step 1. Does management of this waste
pose human health/environmental
problems? Might current practices causa
problems in the future?
Critical to the Agency's decision
making process is whether the special
waste either has caused or may cause
human health or environmental damage.
To resolve these issues, EPA has posed
the following key questions:
1. Has the waste, as currently
managed, caused documented human
health impacts or environmental
damage?
2. Does EPA's analysis indicate that
the waste may pose a significant risk to
human health or the environment at any
of the sites that generate it (or in off-site
use), under either current management
practices or plausible mismanagement
scenarios?
3. Does the waste exhibit any of the
characteristics of hazardous waste?
In the RTC. EPA concluded that
further evaluation was necessary if the
answer to any of these three questions
was yes. However, numerous
commenters argued that several of the
damage cases included in the RTC do
not represent today's conditions, for a
variety of reasons, that the risk
assessment conducted for the RTC tends
to overstate risk, and that the leachate-
concentrations measured using the EP
leach test overestimate actual leachate
concentrations. Although EPA disagrees
with many of the specific points made
by commenters in support of these
arguments, as discussed In appendix A
to this preamble, the Agency believes
that a more flexible decision making
approach is warranted in response to
the general concerns expressed.
Concluding that further evaluation is
necessary if the answer to just one of
the above questions is yes, without
taking into account the overall certainty
and conservativeness of that answer
relative to the answers to the other
questions, could unnecessarily lead the
Agency into Step 2 of the decision
making process.
Therefore, for this regulatory
determination. EPA answered each of
these questions and then considered the
combined answers as a whole in
deciding whether further evaluation was
necessary. A fundamental concept in
this approach was that no one question
is more significant in reaching a
decision regarding potential hazard than
the others, as the answer to one
question could offset, somewhat, the
answer to another. That is. rather than
following a very rigid approach of
proceeding to Step 2 if the answer to just
one question was yes, the Agency
considered how the answers traded off.
taking into account each answer's
supporting weight of evidence and
certainty.
For example, the scenario for a given
waste could be that (1) there was not a
documented damage case that could be
•attributed to the waste with reasonable
certainty (Le.. the answer to question 1
was no); (2) the reasonably conservative
risk analysis provided a sound basis for
concluding that the potential for human
health and environmental problems was
low under current management
practices-or plausible mismanagement
scenarios (l.e.. the answer to question 2
was no); and (3) the waste exhibited the
toxicity characteristic using the EP leach
test (i.e., the answer to question 3 was
yes), but only rarely and never for
samples analyzed using the Synthetic
Precipitation Leaching Procedure (SPLP).
Under this scenario, EPA would have
reached an overall low hazard
conclusion because the balance of the
information supporting the answers to
questions I and 2 effectively outweighs,
in the Agency's judgment the answer to
questions.
By following this approach, the
Agency considered all of the relevant
Information in making its decision on
the potential for each waste to pose
human health and environmental
problems. If this analysis led the Agency
to conclude that there is a reasonable
potential for problems, then EPA
concluded that further evaluation was
necessary. If the conclusion was that the
potential for problems is low. then the
Agency determined that regulation of
the waste under RCRA subtitle C is not
appropriate. EPA believes that this
"balancing" approach to the analysis in
-------
2730S Federal Bagfater / Vol. SB. No. 114 f Thnraday. June 13. 1991 / Roles and Regulations
Step 1 allow* EPA to determine with
more precision the actual hazards posed
by those wastes, consistent with the
intent of the Bevill Amendment. 852 F.2d
at 1314. EPA also notes that this
analysis does not precisely match the
approach EPA uses to lilt or identify
non-special wastes as hazardous, but is
more conservative in the direction of not
imposing regulation unless the potential
risk justifies elimination of special
status.
Step 2. Is more stringent regulation
necessary and desirable?
If the waste has caused or may
potentially cause human health or
environmental impacts as determined in
Step 1, then EPA concluded that an
examination of alternative regulatory
controls was appropriate. Given the
context and purpose of the study, die
Agency focused on an evaluation of the
likelihood that such impacts might
continue or arise in the absence of more
stringent regulation, and whether
subtitle C would be an efficient
mechanism for controlling these •
impacts. Specifically, the Agency posed
three questions:
1. Are current practices adequate to
limit contaminant release and
associated risk?
2. Are current federal and state
regulatory controls adequate to address
the management of the waste?
3. Will Subtitle C effectively address
problems associated with the waste
without imposing significant
unnecessary controls that are
inconsistent with the special status of
the waste?
Due to changes made in response to
public comments, these questions differ
from the questions presented Cor Step 2
in the RTC, in two ways. First, the
Agency eliminated a question
concerning the likelihood of new
facilities opening IB the future and
generating and managing a special
waste in a different environmental
setting than those examined in the RTC.
The Agency acknowledges that this ia •
relevant issue and considered it in die
Report to Congress for each industry
and waste that was stadiad. However.
EPA agrees with public oommeateis that
an analysis of this issue relies largely ea
conjecture about the potential
conditions thai might exist at a new
facility, if OM were to open. Therefore,
the Agency believes that the potential
for problems at hypothetical new
facilities is less importaat than the other
factors considered in the Hflfima
making process, and did not f-^B«iidsr
the question explicitly ia developing the
regulatory determination.
Second, several comnenters argued
that subtitle C regulation, evei with
Section 3004(x) fiexibiicty, would impeae
numerous prescriptive standards that
would not necessarily be needed to
control the problems at a given facility
or across a commodity sector. While
EPA disagrees with many of the specific
points made by these commenters in
support of their arguments, as presented
in the appendices to this preamble, lite
Agency agrees that the suitability of
subtitle C controls relative to the
magnitude and extent of the problera(i)
defined in Step 1 is an important issue tn
the decision making process and the
approach ia also consistent with EPA's
previous approach to making regulatory
determinations under the Bevill
Amendment which focused on whether
subtitle C even with the use of Section
3004(x). might be too " cumbersome and
uncertain" to accomplish the goals at
effective regulation of the risks from
special wastes, or put another way,
whether subtitle C is the right
"template" for regulating the special
wastes at issue. 852 F.2d at 1313, 1315.
Therefore, the Agency added the third
question listed above for the purpose of
developing today's regulatory
determination.
EPA considered the answers
developed for these questions together
with the answers to the questions
addressed in Step 1 to reach aa overall
conclusion on the need for further
evalaation, If current practices or
existing regulatory control were found
to be adequate, or Subtitle C would net
be an effective regulatory ahematrve.
and if the potential for actual furore
impacts was considered low (e.g.,
existing facilities in remote locations,
low ttketihood of actual risk, adequate
federal or state regulatory eontrott
already exist), then the Agency
concluded that the waste should not be
regulated under Subtitle C. Otherwise,
further examination of regulatory
alternatives was considered necessary.
Step 3. What would be the operational
and economic consequences of a
decision to regulate a special waste
under Subtitle C?
If, based upon the previous two stepa.
EPA believed that a waste might be •
candidate for regulation under subtitle
C, then the Agency estimated and
evaluated die costs and impacts of two
regulatory alternatives diat an ba*ed
upon subtitle C and one regulatory
alternative mat reflects one possible
approach that might be taken under
RCRA subtitle 0 ("Subtitle D-Pfa»").
Two evamatioas wen performed. The
first focused oa the '
distribution, and significance of the
incremental costs of regulation under
full Subtitle C as compared to the
Subtitle D-Pios scenario for each
potentially afracted facility. The se^
focused on incremental costs and
impacts associated with regulation
under a modified subtitle C ("Subtitle C-
Minus") scenario, that incorporates
waste management standards based
upon site-specific risk potential, as
compared to Subtitle D-Plus. The key
questions in the Agency's decision
making process for both comparisons
were as follows:
1. Are predicted economic Impacts
associated with the fall subtitle C (or
Subtitle C-Kfimrs in the case of the
second comparison) scenario significant
for any of the affected facilities?
2. Are these impacts substantially
greater than those that would be
experienced wider the Subtitle D-Plus

Federal Register / Vol. 56. No. 114 / Thursday. June 13. 1991 / Rules and Regulations 27307
presented in EPA's July 1990 Report to
Congress and January 1991NODA.
EPA has decided that regulation under
subtitle C is inappropriate for all 20 of
the mineral processing wastes. For nine
of the wastes, no comments were
received that objected to EPA's
tentative determination in the Report to
Congress that regulation under subtitle
C for these wastes is unwarranted.
These nine wastes include:
(1) Red and brown muds from bauxite
refining;
(2] Treated residue from roasting/
leaching of chrome ore;
(3) Gasifier ash from coal gasification:
(4) Process wastewater from coal
gasification;
(5) Pluorogypsum from hydrofluoric
acid production;
(6) Iron blast furnace slag;
(7) Basic oxygen furnace and open
hearth furnace slag from carbon steel
production;
(8) Slag tailings from primary copper
processing; and
(9) Process wastewater from primary
magnesium processing by the anhydrous
process.
For the remaining eleven wastes, EPA
received at least one comment arguing
that subtitle C regulations should be
promulgated. EPA's determination
rationale for each of these wastes
follows.
Slag From Primary Copper
Processing. An examination of available
information regarding copper slag leads
to the following findings regarding the
three key questions outlined above for
Step I in the Agency's decision making
process.
First copper slag rarely, if ever,
exhibits a hazardous waste
characteristic. Only one sample out of
70 exceeded EP-toxicity regulatory
levels, for cadmium and lead. The
Agency agrees with commenters that the
accuracy of the one sample is
questionable, because the cadmium
concentrations in the EP leachate
extract are inconsistently high compared
to concentrations in the total sample
analysis.
Second, although one commenter
pointed out that the slag contains a
number of constituents in
concentrations that exceed the
conservative risk screening criteria used
in the Report to Congress, these
concentrations by themselves do not
demonstrate that the slag poses •
significant hazard. An examination of
the slag management practice* and
environmental conditions at the 10
active primary copper facilities
indicates that copper slag currently
generated at these facilities poses an
overall low risk to human health and the
environment This is largely due to the
fact that most of the active facilities are
located in areas with low-risk
environmental and exposure
characteristics (e.g., very low
precipitation and net recharge, large
depths to ground water, large distances
to surface water, and great distances to
potentially exposed populations). As
pointed out by several commenters, with
whom EPA agrees, the Agency's risk
modeling for copper slag was very
conservative (tending to overestimate
risks) and supports a conclusion that the
slag poses low risks as currently
managed.
Finally, following careful review of
the information and public comments on
the copper slag damage cases, EPA
believes that the damages documented
in the RTC for copper slag resulted from
unusual circumstances that generally do
not represent current management
practices. For example, the damages at
Commencement Bay (Puget Sound) were
caused by the use of copper slag, as well
as other wastes, as fill in a wetland or
tideflats area. The nearby copper facility
that generated the slag is now inactive,
and the ten active primary copper
processing facilities are generally
concentrated in arid areas where it is
very unlikely that slag could be
disposed of in a wetland. Similarly, at
the inactive copper facilities in Midvale,
UT and El Paso, TX. environmental
contamination has been caused by the
co-management of slag from copper,
lead, and/or zinc processing since the
late 1800's. Based on the available
damage case information, survey
responses, and public comments, EPA
believes that these cases do not reflect
the industry norm today. In addition.
EPA presently does not have damage
case information that suggest* that
current copper slag management
practices are causing problems.
Based on these findings, EPA
concludes that current management of
copper slag does not appear to pose
significant human health or
environmental hazards, and current slag
management practices appear unlikely
to cause problems in the future. A* a
result Federal regulation under subtitle
C is not appropriate. Given this finding,
EPA did not evaluate the questions
addressed in Steps 2 and 3 of the
decision making methodology.
Slag From Elemental Photphomt
Production. Addressing the questions in
Step 1 of the decision making process,
the information included in the RTC and
provided in public comments leads to
the following major findings for
elemental phosphorus slag.
First elemental phosphorus slag does
not exhibit any of the four
characteristics of hazardous waste. One
commenter contends that the slag is
intrinsically dangerous because it is
radioactive and contains toxic
constituents. EPA agrees that the
radionuclide content may pose a direct
radiation threat when the slag is used
off-site. (See further discussion on this
issue later in this section and in section
IV.) However, the slag contains few
chemical constituents that exceed the
RTC's conservative risk screening
criteria by a significant margin, and
none exceed regulatory levels that
would qualify the slag for subtitle C
controls.
Second, current on-site slag
management practices and
environmental conditions at the five
active elemental phosphorus facilities
generally pose a low risk via the ground-
water and surface water exposure
pathways. Significant risks via these
pathways are limited by the low
concentrations of potentially harmful
constituents in slag leachate and the
generally large size of slag particles that
limit stormwater erosion potential. In
addition, the potential for the slag piles
to cause significant impacts-to surface
water is precluded by the relatively
great distance (more than 500 meters) to
the nearest water body at two facilities,
the use of stormwater run-off controls at
the slag piles at two facilities, and the
large flow and assimilative capacity (30
cubic meters per second or 1.058 cubic
feet per second) of the creek closest to
the fifth facility. As the RTC and one
commenter point out one of the sites is
located within a mile of a wetland, one
site overlies an area of karst terrain, and
one facility is located in a National
Forest While these facts are pertinent
the Agency believes, based on all the
evidence, that existing management
practices for elemental phosphorus slag
should not significantly threaten these
environments through the ground-water
and surface water pathways, given the
small potential for releases to these
media.
Moreover, although one commenter
points out that ground-water
contamination has been observed at
three of the five active facilities,
available information on the
documented damages at elemental
phosphorus facilities indicates that the
ground-water contamination is due to
other wastes and waste management
practices (e.g., historic unlined ponds
used to store process wastewater). This
supports the above finding that on-site
management of the slag does not pose a
significant ground-water risk.
On-site management at three
facilities, however, may pose a
-------
2730S Federal Register / Vot 56, No. 114 / Thursday, June 13, l«9t / Rule* and Regulation
moderate risk via the air exposure
pathway due to the chromium, cadmium.
and uranium-238 concentrations in the
slag. Although the vitrified nature and
generally large size of particles tends to
limit wind erosion, there is some
evidence that dust from slag piles may
be blown into the air and potentially
lead to exposures. As noted in the RTC
and reiterated by one commenter. three
of the facilities are located in fairly
densely populated areas and three are
located in agricultural areas where
airborne deposition and subsequent
food chain exposures are possible.
Based on these findings. EPA
concludes that current on-site
management practices for elemental
phosphorus slag do not appear to pose a
significant ground-water or surface
water risk and are not lively to cause
significant problems through these
pathways in the future. However, there
is some potential for airborne releases
and resulting impacts; because of the
Agency's desire to fully evaluate all
potential risks, the Agency proceeded to
Step 2 of its decision making process to
evaluate whether more stringent
regulation is necessary and desirable.
In this step, EPA made three bask
findings:
• The relatively low to moderate risk
from the on-site management of
elemental phosphorus slag la expected
to continue hi the future in the absence
of subtitle C regulation given current
waste management practices and
environmental conditions at the five
active facilities. The slag characteristics
and existing management practices at
the five active facilities are unlikely to
change significantly.
• None of the states where elemental
phosphorus slag is generated
specifically apply fugitive dust control
requirements to slag piles. However.
adequate authority and mechanisms
already exist under the Clean Air Act to
control this dust. For example, the
National Ambient Air Quality Standards
include a standard for the airborne
concentration of particulate matter, and
the dust could be controlled under the
National Emission Standards for
Hazardous Air Pollutants, if necessary.
• Regulation under subtitle C would
impose significant and specific
requirements (e.g.. linen, caps, ground-
water monitoring) that are directed at
controlling releases/risks that do not
appear to exist or are otherwise
controlled and. thus, are not appropriate
given the special status of the waste.*
Baaed on these combined findings
from Steps 1 and 2, EPA concludes that
regulation of elemental phosphorus slag
under subtitle C is not appropriate under
the circumstances. (Accordingly, EPA
did not proceed to Step 3 of its decision
making process.) EPA plans to further
examine the potential impacts of fugitive
dust emissions from elemental
phosphorus slag piles and will
determine whether controls for these
releases are needed, and if so. whether
they can be developed mnder the Clean
Air Act
The Agency is uncertain about the
potential gamma radiation exposures
and risks associated with off-site use of
elemental phosphorus slag in
construction and land reclamation. As
discussed in more detail in section FV of
this preamble, the Agency has
postponed any decisions about the
significance of this risk and the need for
additional control of off-site uses
pending more extensive review. In
response to comments. EPA
acknowledges that the RTC is in error in
its statement that radon emissions from
elemental phosphorus stag pose
significant risks, as other EPA studies
clearly show that the slag is not a
significant source of radon emissions.
However, the fact that radon gas
emissions from elemental phosphorus
slag an inconsequential does not
eliminate concern about the potential for
direct exposure to gamma radiation
emitted from the slag.
SlagFraa Primary Zinc Pnceiaiag.
Regarding the question* raised in Step 1
of the Agency's decision making
process, a careful review of the RTC
information and public comments on
zinc slag leads to the following out*
conclusions.
Based on available data, zinc slag
frequently exhibits EP-toxicity, as 25 of
37 samples contained lead in
concentrations that exceed the EP-
toxteity regulatory level by a factor of
between 6 and 13. Using the SPLP test.
however, lead concentrations never
exceeded the EP toxicity regulatory
level although the SPLP test has been
shown on occasion to underestimate the
amount of teachable lead in a sample.
At the same time, based on a review
of existing waste management practices
and predictive modeling results. EPA
believes that zinc slag, as currently
managed at the sole active factittr in
Monaca. PA. poses an overall low risk
to human health and the environment
For example, the Agency predicts that
metals leached from sine stag at Am
Monaca facility would be largely bound

to subsurface soil and would aot reach
the deep naeable aquifer within 200
yean. Even if a shallower aquifer exisls
at t-.z Mle as die RTC and one
cotn-sster suggest, any shallow gru^
water that may become contaminated
with siag leachate is Ukerf to discharge,
without being withdrawn for human use,
into the adjacent Ohio River via the
steep bluff adjoining the site. The Ohio
River is very large at this point, and EPA
modeling predicts that it can readily
assimilate any chronic loading of
contaminants that may occur, and any
such release would be controlled
through permitting under the Clean
Water Act
A portion of the zinc slag is also sold
for use at off-site locations as road
gravel or construction aggregate, and
another portion is stockpiled until it caa
be sold for off-site use as a source of
iron. Given the high concentrations of
lead measured in EP leach tests of zinc
slag, EPA recognizes that possible off-
site use locations may be more
condoerw to releases and risks than the
existing processing facility in Monaca,
PA. although the Agency has no
evidence that such risks are occurring or
would occur, m fact the Agency did not
discover any damages attributable to
such slags used off-site.
Third. EPA did not discover any
damage cases attributed to zinc si
the Monaca facility. Damage case
studies at inactive sites did demonstrate
the potential lor surface water
contamination via stormwater run-off
from zinc slag piles, however. While
these cases demonstrate the potential
for problems if zinc slag is not properly
controlled, they do not by themselves
indicate that more stringent controls are
needed for slag at the one active facility.
la fact, the lack of documented damage
associated with the active facility
supports the conclusion that zinc slag as
currently managed at that facility poses
a low risk. One cosameater argued that
the lack of damage case data from the
active facility may be a reflection of the
inadequacy of the facility's
environmental monitoring system, and
not the absence of actual damage.
However, the Agency believes that slag
at the Monaca facility does not pose a
threat, principally because the slag
composition at the Monaca facility is
not considered comparable to diet of the
inactive facilities, Le« it arises from
feedstocks earring a different chemical
composMea. It saoold also be noted that

evidence of damages resulting from the
management of zinc slag.
The Agency considered these findings,
by themselves, to be insufficient to
support a final regulatory determination.
Although on-site risks and damages at
the sole active facility are low. the
elevated EP leachate concentrations (as
well as difficulties in interpreting the
low SPLP leachate concentrations) and
the prospect of zinc slag being managed
at off-site locations that may present a
problem prompted the Agency to
proceed to Step 2 of its decision making
process to determine whether more
stringent regulation is necessary and
desirable. In answer to the questions
addressed in Step 2. the Agency found
that:
• The waste management practices
and environmental conditions that
currently limit the potential for
significant threats to human health acd
the environment at the Monaca facility
are expected to continue in the future in
the absence of subtitle C regulation.
Similarly, management practices at off-
site locations would not be expected to
change significantly. The characteristics
of the slag are also unlikely to change in
the future.
• EPA's recently promulgated
stormwater regulations (55 FR 47990,
November 16* 1980} under the Clean
Water Act will minimize the potential
for adverse impacts of stormwater run-
off from zinc slag piles in the future.
• The only potential problem
associated with these slags that EPA
has identified is with their off-site use or
disposal However, the Agency has no
evidence that such, use or disposal is
resulting in environmental damage.
Control under subtitle C would impose
tiignificant and specific requirements
(e.g., liners, closure and post-closure
care) that are directed at controlling
teleases/risks that do not appear to-
exist or are otherwise controlled and,
thus, are not appropriate given the
special status of the waste.
Finally, the Agency notes that the State
cif Pennsylvania has proposed
regulations that would impose more
stringent environmental controls on the
en-site management and off-site use of
zinc slag, although the exact nature and
extent of these controls cannot be
predicted with certainty. The proposed
rule would require generators to certify
tiat they have attempted to reuse andV
or recycle the slag before disposal ami
v/ould require permits to contain
provision* for liners, leachate collection
systems, monitoring wells, and disposal
ofleachsrte.
Beees) on these combined, findings
from Steps 1 and 2. EPA concluded that
regulation of sine slag under subtitle C t>
inappropriate under the circumstances.
(As a result the Agency did not proceed
to evaluate the questions addressed in
Steo 3 of its decision malting process.)
Air Pollution Control (APC) Dust/
Sludge From Iron Blast Furnaces,
Addressing the questions in Sfep 1 of the
decision making process, the
information provided in the RTC and in
public comments on the RTC leads to
the following findings for this waste.
First. EPA found that lead
concentrations measured in iron blast
furnace APC dust/sludge leachate using
the EP leach test only occasionally
exceeded the EP-toxicity regulatory
level (4 out of 70 samples from 3 out of 16
facilities with data). In addition, the
waste is recycled (completely at one
facility and partially at another) at two
of the three facilities where the waste
was found to be EP-toxic. Although lead
concentrations determined by SPLP
analyses never exceeded the EP toxidty
regulatory level the Agency has
difficulty interpreting these
measurements because the SPLP test
has been shown on occasion to
underestimate the amount of teachable
lead in s sample.
At the same time, based on an
examination of the site specific
conditions at 15 of the 26 facilities that
generate this waste, current
management practices and
environmental conditions are highly
variable, with the potential for
contaminant releases existing at some
sites. For example, there is potential for
ground-water contamination at five
facilities that manage at least some of
the dust/sludge in surface
impoundments, although the low EP
leachate concentrations at these
facilities (none exceeded the EP-toxicity
regulatory levels) would appear to
suggest that any such contamination
would not likely be significant The
dot/sludge also consists of small
particles that are amenable to release
and transport via stormwater and wind
erosion when the wsste is managed in
exposed piles. Due to site-specific
management practices and
environmental conditions, there appear*
to be some potential for migration into
surface water at four facilities and a
potential for airborne releases and
exposures at seven facilities.
One commenter argued that risks
posed by this waste could be
substantially higher than repotted,
because, as the commenter pointed out.
the RTC did not consider the site-
specific conditions at all active fatiattesv
inactive facilities that could be
reactivated in the future, end potential
new facilities. While the commenter
raises a good point the Agency notes
that the sample of facilities examined hi
the RTC represents more than half (15)
of the 26 active facilities and seven of
the ten states where active facilities are
located. Furthermore, the conditions
examined in the RTC represent a wide
diversity of management practices and
environmental conditions. Specifically.
all known management practices for the
dust/sludge were represented by the 15
sample facilities, including disposal
methods (landfills and ponds) and
temporary storage methods (storage
pads and transfer areas), such as might
be present at facilities that recycle the
waste or send it off-site for disposal.
Some of these units are equipped with
engineered controls to prevent releases
(e.g., liners and run-off controls}, while
others are not In terms of
environmental conditions, the facilities
examined represent a variety of depths
to ground water, net recharge rates,
distances to surface water, and
proximities to potential receptors. As a
consequence, the Agency believes that
the faculties examined reasonably
represent the conditions that might exist
at the other facilities. EPA thus believes
that the hazards that were evaluated
reflect the diversity and nature of
hazards posed by iron blast furnace
APC dust/sludge at the other facilities.
Finally, despite the Agency's
theoretical conclusions about the
potential for iron blast furnace APC
dust/sludge to be released into the
environment at tome facilities, EPA did
not find any riatn»g« cases attributable
to this waste, which EPA believes to be
significant when evaluating the actual
hazards posed by special wastes. One
commenter alleged that there are such
documented damage cases, but that EPA
did not discover them because it did not
review files for inactive sites and other
key information sources. However, as
stated in the Agency's responses to
comments on the RTCs analytical
methodology (see appendix A of this
preamble), the Agency maintains the
view that its damage case investigation
effort for these and other wastes was
comprehensive and thorough. The
Agency closely evaluated the specific
information sources referenced by the
commenter and. though the information
clearly shows environmental problems
at ferrous metal production facilities,
EPA does not believe thai the damages
can be attributed ID the special wastes
studied in the Report to Congress. For
example, surface water and ground-
water impacts were found related to
"slag landfills" at two facilities, but the
landfills contained a number of co-
disposed wastes, incfading sludges, fly
-------
27310 Federal Register / Vol 50, No. 114 / Thursday. June 13. 1991 / Rules and Regulations
ash, waste acid, and coke plant tars, all
of which may have contributed to the
observed impacts.
In summary, this waste exhibits
hazardous waste characteristics only
rarely—only three facilities out of 18
with data generate dust/sludge that
exhibits the toxicity characteristic, and
even then the data suggest that the
waste exhibits the characteristic only
occasionally. Moreover, the waate is
recycled (completely at one facility and
partially at another) at two of the three
facilities where it occasionally exhibits
the toxicity characteristic. The Agency
recognizes that existing waste
characteristics, management practices,
and environmental conditions could
lead to releases at selected facilities.
However, the low EP leachate
concentrations at most facilities, and the
lack of documented cases of damage
attributable to the dust/sludge indicate
that the potential effects of such
releases are not of sufficient magnitude
to warrant removal of the special status
of these wastes. In addition. EPA's
recently promulgated stormwater
regulations (55 FR 47990, November 16,
1990) under the Clean Water Act will
minimize the potential for adverse
impacts of stormwater runoff from the
dust/sludge. Based on these findings,
EPA concludes that regulation of this
waste under subtitle C is inappropriate
under the circumstances. (Accordingly,
the Agency did not evaluate the
questions addressed in Steps 2 and 3 of
its decision making process.)
Basic Oxygen Furnace and Open
Hearth Fumaca Air Pollution Control
(APC) Dust/Sludge From Carbon Steel
Production. Based on a review of
information in the RTC, supplemental
analysis, and public comments on steel
APC dust/sludge. EPA's responses to
the questions in Step 1 of the decision
making process are basically the same
as those outlined above for iron blast
furnace APC dust/sludge. Specifically:
• Steel APC dust/sludge appear* to
be EP-toxic only rarely. Of seven
samples analyzed from five facilities.
the concentration of selenium exceeded
the EP-toxicity regulatory level in only
one sample, and in this on* case, only
by a factor of 1.5. Selenium
concentrations as determined by SPLP
analyses did not exceed the EP-toxicity
level
• Based on an examination of the
site-specific conditions at 11 facilities
that generate the dust/sludge, current
management practices and
environmental conditions are highly
variable, with the potential for
contaminant releases existing at certain
facilities. Like the iron blast furnace
APC dust/sludge, however, there
appears to be only a minor potential for
ground-water contamination at a few
facilities that manage the steel APC
dust/sludge in impoundments. The steel
APC dust/sludge consists of small
particles that would be amenable to
release and transport via stonnwater
and wind erosion if the waste is not
properly controlled.
• EPA did not identify a single case of
documented damage that can be
attributed to steel APC dust/sludge.
Based on these findings, EPA
concludes that subtitle C regulation for
steel APC dust sludge is inappropriate
under the circumstances that exist
(Therefore, the Agency did not employ
Steps 2 and 3 of its decision making
methodology.) The basic rationale for
this conclusion is the same as that for
iron blast furnace APC dust/sludge.
That is, the dust/sludge rarely if ever
exhibits a characteristic of hazardous
waste. Although existing management
practices and environmental conditions
have the potential for environmental
releases at certain facilities (although no
evidence exists that such contamination
has occurred or would occur), the
waste's low contaminant concentrations
and lack of damage cases indicate that
the potential for adverse effects is not of
sufficient magnitude to warrant removal
of the special status of the waste. Thus.
to the extent that additional controls
may be justified, and state management
controls an deemed to be inadequate,
EPA may pursue appropriate controls
for steel APC dust/sludge management
under the Subtitle D program being
developed for mineral extraction and
beneficiation wastes.
Calcium Sulfate Wastewater
Treatment Plant Sludge From Primary
Copper Processing. In the Report to
Congress. EPA tentatively recommended
subtitle C regulation for this waste
under Approach IB. However. EPA
received data in comments indicating
that only one facility now generates and
disposes of this sludge. In addition, as
outlined in section II of this preamble,
the Agency modified Step 2 of it»
decision making methodology in
response to public comments to
deemphasize consideration of potential
threats that could exist at any new
facilities that open in the future in favor
of the other Step 2 factors, in light of the
speculative nature of EPA's predictions
regarding industry expansion. The
possibility of expansion was an
important factor contributing to the
RTCs Subtitle C recommendation for
this waste. EPA. therefore, has
reconsidered the RTC tentative
recommendation, focusing only on the
remaining active generator (located in
Garfield. UT).
Addressing the three questions
considered in Step 1 of the decision
making process:
• The sludge at the Garfield facjj
EP-toxic for arsenic (7 out of 7 sac
average 44 times the regulatory levelJT
cadmium (6 of 7 samples average 3 times
the regulatory level), and selenium (7 of
7 samples average 5 times the regulatory
level). SPLP leach test concentrations.
however, were below the subtitle C
regulatory levels for all of the samples
analyzed.
• One commenter argued that calcium
sulfate sludge poses a large risk that
should be controlled under subtitle C:
however, based on a review of existing
management practices and the arid
setting of the Garfield facility, EPA
believes that the hazards associated
with calcium sulfate sludge at this site
are low. Predictive modeling that
accounts for the low net recharge and
high evaporation rate, depth to ground
water, and clayey subsurface at the site
indicates that the potential for ground-
water contamination is very low.
Similarly, the potential for significant
surface water contamination is
negligible given the great distance of the
sludge management units to the nearest
surface water body (over 2 miles to the
Great Salt Lake), and windblown
dusting is significantly limited by the
surface crust that forms on the dr
sludge.
• No cases of documented dar
caused by the sludge at the one active
facility were discovered by EPA.
Even though the site-specific risk
findings and lack of damage cases
indicate that management of the sludge
does not pose human health or
environmental problems, the high
intrinsic hazard of the sludge compelled
EPA to consider additional factors
before reaching a final regulatory
determination. Therefore, EPA
proceeded to Step 2 of its decision
making process to examine whether
more stringent regulation is necessary
and desirable.
In Step 2, EPA found that current
practices at the Garfield facility appear
adequate to limit contaminant releases
and associated risks in the future in the
absence of subtitle C regulation. The
sludge is well managed at present and
the potential for releases appears to be
precluded by the environmental
conditions at this site. Specifically.
potential release* to ground water are
significantly limited by the site's very
arid setting (liquids discharged to
impoundment* along with the sludge are
expected to quickly evaporate and little
precipitation and recharge is i
to carry contaminants to the
-------
Federal Regnter / Vcl. 5fl£ No. 114 / Thursday; June 13, 199T / Rules and Regulations 27811
subsurface), clayey subsurface, and
depth to ground water (8 meters to the
water table and 90 meters to the
uppermost uaeable aquifer). Because die
nearest surface water near the sludge
units, the Great Salt Lake, is over two
miles away, significant releases to
surface water also should not be a
problem. Finally, the potential for
significant releases to air is limited
because a surface crust forms on the
dried sludge, largely preventing the
wind from blowing dust into the air, and
because the dried sludge is exposed to
the wind only temporarily before it is
stabilized and buried in an on-site
landfill.
EPA also found in Step 2 that existing
state regulatory programs provide only
limited controls over the management of
calcium sulfate sludge. Some
commenters argued that the RTC's
analysis of state regulations
significantly understates the regulatory
requirements applicable to copper
processing wastes. However, upon
further consideration of available
information and communication with
state officials. EPA concludes that the
states have been regulating copper
processing wastes, including calcium
sulfate sludge, only to a limited extent
However, as discussed below, the
Agency does not believe, based on
available information, that this limited
regulation has resulted in any
environmental problems.
Finally, EPA also concluded in Step 2
that Subtitle C regulation of calcium
sulfate wastewater treatment plant
sludge would impose significant and
specific requirements (e.g., linen, caps,
ground-water monitoring) that are
directed at controlling releases/risks
that do not appear to exist or are
otherwise controlled and. thus, are not
appropriate given the special status of
the waste.
Based on these combined findings
from Steps I and 2, EPA concluded that
existing sludge management practice* at
the one facility in question currently
limit the potential for damages.
Therefore, considering all of these
findings together, EPA concludes that
subtitle C regulation of calcium sulfate
sludge is inappropriate given the
existing circumstances. (Accordingly,
EPA did not evaluate the question*
addressed in Step 3 of its decision
making methodology.) EPA may address
the generation and management of this
sludge under the subtitle O program
under development for the mining
industry.
This subtitle D determination differs
from the RTC's tentative
recommendation for two reasons. Pint
potential human health and
environmental problems at one copper
processing facility were dropped from
consideration because public comments
indicate that the facility no longer
generates and disposes of calcium
sulfate stodge. Second, the Agency
agreed with commenters that concerns
expressed in the RTC about potential
problems at new facilities that may open
in the future are somewhat speculative.
Therefore, EPA did not place as much
weight on these concerns in making the
regulatory determination as it did in the
RTC.
Chloride Process Waste Solids from
- Titanium Tetrachloride Production. In
the RTC, EPA tentatively recommended
subtitle C regulation for this waste
under Approach IB. However,
additional data submitted in public
comments and reanalysis of the RTC
data indicate that the waste is not EP-
toxic for lead as indicated in the RTC •
and. therefore, is EP-toxic only for
chromium. In addition, this waste would
currently be exempt from subtitle C
regulation by 40 CFR 261.4(b)(6), which
exempts wastes that are hazardous only
because they exhibit the EP toxitity
characteristic for chromium, contain
only trivalent chromium, and are
managed in non-oxidizing environments.
For these reasons, EPA decided to
reevaluate the RTC's tentative
conclusions.
Considering the three questions in
Step 1 of the Agency's decision making
process, the Agency has made the
following findings. First, the waste is
characteristically hazardous only as a
result of its chromium content, which is
currently exempted from regulation
under subtitle C of RCRA by
S 261.4(b)(8](i)(A). In addition, chromium
concentrations in the waste solids
measured using the SPLP leach test are
below the EP-toxicity regulatory levels.
as indicated by further analysis of the
RTC data and information submitted in
comments.
Second, based on an examination of
existing conditions at the nine active
titanium tetrachloride facilities, EPA
found that current management of the
waste solids may allow contaminants to
migrate in the environment at certain
sites, but that the potential for this
migration to cause significant impacts is
low. For example, there appears to be a
potential for leachate from this waste to
reach ground-water at half of the sites,

but predictive modeling at the "most
sensitive" site indicates that
contaminant concentrations at the
property boundary would be below
drinking water standards. Similarly, the
Agency's modeling predicts that
concentrations of contaminants in
surface waters near the sites would be
well below human health and
environmental protection benchmarks,
and that the risks associated with the
inhalation of windblown dust from the
waste solids piles would be negligible.
One commenter argued that the risks
posed by this waste are sufficiently high
to warrant regulation under subtitle C.
In particular, the commenter argued that
chemical concentrations (e.g., of
chromium, lead, radium, and arsenic) in
the waste solids could be much higher
than the few samples examined in (he
RTC. that the wastes threaten fragile
ecosystems near several of the facilities.
and that drinking water threats could
exist if private wells were installed
closer to existing facilities. While EPA
agrees there is always a possibility that
the waste could contain higher chemical
concentrations than those reported, the
Agency used 17 samples from 7 facilities
and believes the resulting
characterization of the waste is
adequate. The Agency also recognizes
that several sites are located near
"fragile" ecosystems: Six of the nine
active facilities are located within 1,600
meters (1 mile) of a wetland, one is
located within 2,600 meters of an
endangered species habitat, and three
are located within 1,600 meters of a
National Park, Wildlife Refuge, or
Recreation Area. However, the Agency's
conservative modeling predicts that it is
very unlikely that contaminants
released from the waste solids
management units could migrate to
these areas in harmful concentrations.
Finally. EPA's ground-water modeling
for the "worst-case" facility predicts
that contaminant concentrations at the
property boundary are below health-
baaed and ground-water protection
criteria. Therefore, it does not appear
that releases to ground water would
pose a serious threat to the
environments surrounding each plant.
Third. EPA found no documented
cases of damage attributable to titanium
tetrachloride waste solids. No evidence
of damages was uncovered in the RTCs
comprehensive review of all nine active
and two inactive titanium facilities, and
no new damage case information was
submitted in public comments.
Based on these findings. EPA
concludes that regulation of titanium
tetrachloride waste solids under RCRA
Subtitle C is inappropriate under the
-------
27312 Federal Register / Vol. 56, No. 114 / Thursday. June 13. 1991 / Rules and Regulations
circumstances. (Accordingly, the Agency
did not evaluate Steps 2 and 3 of the
decision making methodology.) Current
on-site management practices do not
appear to pose a significant risk. In
addition, management practices are
likely to be improving because the
waste is currently comanaged with
waste acids from titanium tetrachloride
production, a waste that recently
became subject to subtitle C controls.
EPA plans to follow closely the changes
in management practices that are
expected to result from the change in
regulatory status of the waste acids.
changes that in some cases may result in
management of the waste solids in units
subject to subtitle C requirements. At
those facilities where the waste is not
managed in units regulated under
subtitle C. EPA believes that releases
that may occur can be adequately
addressed under subtitle 0 given the
special status of these wastes. In
addition, in the final Toxicity
Characteristic rulemaking, EPA
indicated that it would re-evaluate the
trivalent chromium exemption in
§ 261.4(b)(6) (55 FR11812. March 29.
1990). If EPA finds that this exemption is
not protective of human health and the
environment and if an examination of
titanium tetrachloride waste
management shows any continuing or
new problems, the Agency will
reconsider this subtitle D determination
for chloride process waste solids from
titanium tetrachloride production.
Today's subtitle 0 determination is
warranted and differs from the RTC's
tentative recommendation primarily due
to changes in the data base used to
characterize the waste, such that the
waste only exhibits the toxicity
characteristic of hazardous waste for
chromium and is exempt from subtitle C
regulation. As discussed above.
consideration of changes in management
practices for waste solids that are
expected as a result cf the classification
of waste acids from titanium
tetrachloride production as a hazardous
waste supports a subtitle 0 decision. In
addition, if the decisionmaking process
had been carried to Step 2, the fact that
the Agency modified Step 2 of its
decisionmaking methodology (in
response to public comments) to
deemphasize consideration of potential
threats that could exist at any new
facilities that open in the future, would
also have contributed to the change
from the subtitle C tentative
recommendation in the RTC to today's
subtitle D regulatory determination.

however, provided a clearer picture of
the three damage cases presented in the
Report and the risks associated with one
facility's practice of shipping its slag off-
site for disposal. EPA. therefore.
reconsidered the RTC's tentative
recommendation to account for this
additional information.
Addressing Step 1 in the Agency's
decision making process, which
evaluates whether management of the
waste poses human health or
environmental problems. EPA made four
basic findings. First, lead slag is EP-
toxic using results of the EP leach test:
EP-toxicity leach tests show that lead
exceeded the regulatory level at all five
active facilities in a total of 27 out of 101
samples; the maximum lead
concentrations exceeded the regulatory
level by a factor of 19. Cadmium
concentrations exceeded the regulatory
level at two facilities, by as much as a
factor of seven. Arsenic, mercury, and
selenium concentrations also exceeded
the regulatory levels at the one facility
that is only a refinery (the other
facilities are either combined smelters
and refineries or, in the case of one
facility, only a smelter). No samples
analyzed using the SPLP test contained
contaminants in concentrations above
the EP-toxicity regulatory levels;
however, the SPLP test has been shown
on occasion to underestimate the
concentration of teachable lead in a
sample.
Second, current practices for
managing lead slag at the five active
lead processing facilities appear to limit
the potential for significant impacts
caused by the slag. The potential for
lead slag to cause significant surface
water contamination at all but one
facility is limited by the use of control
systems that retain and treat stormwater
run-off from slag piles prior to discharge.
or by an expected small contaminant
loading that is well within the
assimilative capacity of nearby water
bodies and is subject to control under
the Clean Water Act. Risk modeling
indicates that stormwater erosion of a
lead slag pile at one facility could result
in surface water contamination.
However, due to releases to ground
water from unlined wastewater ponds at
this facility, the site is presently being
cleaned up under the Superfund
program, and any potential surface
water impacts associated with erosion
from the slag pile will be addressed as
part of the site's overall Superfund
response. EPA's recently promulgated
stormwater regulations (55 FR 47990.
November 16.1990) under the Clean
Water Act will also minimize the
potential for adverse impacts of
stormwater runoff from lead slag.
The Agency's modeling indicates
it is possible for some contaminants to
leach from lead slag piles at two of the
active facilities and migrate into
underlying ground water. However.
increased on-site concentrations of
constituents in ground water are
expected to be well within applicable
drinking water standards. Air pathway
modeling also indicates that it is very
unlikely for lead slag piles to cause
harmful concentrations of contaminants
in the air at the nearest residences. One
commenter contends that lead slag
should be regulated under subtitle C
because windblown dust from slag piles
could pose a significant risk by resulting
in an accumulation of contaminated
dust in residential areas where people
could be exposed directly. However, a
Remedial Investigation/Feasibility
Study at the facility in East Helena. MT
has shown that slag management is a
very minor contributor to windblown
particulate matter and accumulated dust
in the site environs.7 As much as 95
percent of the lead particulate matter
measured in air near the East Helena
facility was found to come from ore
processing areas and other sources, not
the slag piles.
Third, there is a greater potentia^^V

although the Agency has no evidence
that such management does present a
substantial hazard. Although the total
quantity of slag that is shipped to these
off-site landfills represents only 3
percent of the total quantity of slag that
is generated, the slag that is shipped off-
site is the highly concentrated refinery
slag that is consistently EP-toxic for
mercury, lead, cadmium, arsenic, and/or
selenium.
Fourth, historical slag management
practices have clearly caused ground-
water contamination at one site, but
steps have since been taken to help
prevent this contamination from
occurring in the future. The RTC
reported damage cases at two other lead
facilities, but close examination of the
RTC data and information submitted in
public comments has eliminated one of
the damage cases and called the other
one into question. Specifically, EPA's
ongoing Superfund evaluation at the
lead facility in East Helena. MT has

Federal Register / Vol. 56, No. 114 / Thursday. June 13, 1931 / Rules and Regulations 27313
demonstrated that ground-water
contamination at that site has been
caused by two on-site wastewater
impoundments. Contribution to the
problem from the lead slag pile is
thought to be limited, though further
study is planned. At the other site,
located in Boss, MO, observed ground-
water contamination is not clearly
attributable to slag, as it too may have
been caused by nearby wastewater
impoundments. The Agency's risk
modeling predicts that ground-water
contamination from the slag pile at this
site is unlikely.
Based on these findings, EPA
concludes that the potential for lead slag
to cause significant impacts is limited by
the current management practices and
conditions at the five active facilities,
but there is some potential for adverse
impacts that may be caused by the off-
site disposal of relatively small
quantities of lead slag from one facility.
Therefore, EPA proceeded to Step 2 of
its decision making process to evaluate
whether more stringent regulation is
necessary and desirable. In this step of
the process, EPA found that:
• Current practices at the off-site
landfills that are receiving lead slag for
disposal may not be adequate to limit
contaminant release and associated
risk. As mentioned above, these are
municipal landfills that may or may not
be adequately equipped to contain
contaminant migration from lead slag.
• In Nebraska, where all of the
present off-site disposal of slag takes
place, the slag could continue to be
managed at off-site locations in the
future with minimal state regulation.
The other states where primary lead
processing occurs have varying degrees
of regulatory control. The State of
Missouri, for example, where three
facilities are located, has recently
developed strengthened permitting.
closure, maintenance, and financial
assurance requirements for facilities
that manage mineral processing wastes.
In addition, stormwater run-off from
lead slag piles into nearby surface
waters is subject to control under the
Clean Water Act in all three states
where the slag is currently managed.
• Because subtitle C regulation would
subject the slag to strict hazardous
waste management standards, it would
prevent the disposal of slag in municipal
landfills. However, a subtitle C
determination for this waste would also
impose significant and specific
requirements for on-site management
(e.g.. liners, closure and postclosure
care, ground-water monitoring) that are
directed at controlling releases/risks
that do not appear to exist or are
otherwise controlled at the five active
lead processing facilities and. thus, are
not appropriate given the special status
of the waste. In particular, the Agency
does not believe that it is appropriate to
subject the entire industry to stringent
subtitle C controls when any potential
problems appear to be associated
primarily with only 3 percent of the lead
slag that is currently produced.
Based on the combined findings from
Steps 1 and 2, EPA concludes that
regulation of the waste under subtitle C
is inappropriate under the
circumstances. (Accordingly, EPA did
not proceed to evaluate the questions
addressed in Step 3 of its decision
making process.) The Agency, therefore,
will work to ensure that both on-site and
off-site slag management practices are
adequately protective under subtitle D
and under the Clean Water Act. In
particular. EPA will investigate further
the offsite disposal practices used by the
Omaha facility to determine the extent
to which slag is currently co-disposed
with municipal waste. If the
management of this waste does prove to
be problematic, EPA may, for example,
classify co-disposal of the slag with.
municipal wastes as open dumping
under RCRA section 4004. Open
dumping is a prohibited practice under
criteria promulgated under section 4004.
This determination differs from the
RTC's tentative recommendation
primarily because the Agency closely
reexamined the three lead slag damage
cases discussed in the Report to
Congress in response to public
comments. As outlined above, this
examination determined that controls
have already been established at one
site to address the problem, that another
case appears to be mainly if not entirely
due to wastes other than lead slag, and
that attribution of the third case to slag
management practices is questionable.
Therefore, an important factor in
tentatively recommending Subtitle C
regulation in the RTC has been removed.
Process Wastewater From the
Production of Hydrofluoric Acid. EPA
tentatively recommended subtitle C
regulation for hydrofluoric (HF) acid
process wastewater under Approach 1A
and IB in the Report to Congress.
Additional data submitted in public
comments and follow-up with the State
of Louisiana, however, confirm that the
documented damages cited in the Report
are attributable to phosphoric acid
wastewaters. and not HF process
wastewater as reported in the RTC. EPA
also found that two of the three active
HF acid production facilities neutralize
their wastewater. Accordingly, EPA has
reconsidered the RTC's tentative
recommendation.
Reconsidering the three questions
addressed in Step 1 of the Agency's
decision making process, the Agency
reaches three basic findings. First, all
nine samples of-process wastewater
analyzed (from two of three active
facilities) exhibited the hazardous waste
characteristic of corrosiviry. However.
no constituent concentrations exceeded
EP-toxiciry regulatory levels (all eight
inorganic constituents with EP toxicity
regulatory levels were measured in
concentrations that were no more than
0.6 times the regulatory levels).
Second, as the RTC and one
commenter who argued for subtitle C
regulation pointed out, there is a
relatively high potential for process
wastewater to migrate into shallow
ground water at the three active
facilities. However. EPA does not
believe that this migration will pose
significant health risks, either because
the shallow ground water is not likely to
be used at close downgradient distances
or because the waste management units
are equipped with controls (e.g., a
monitoring well network and slurry
walls) to detect and help contain
ground-water contamination.
One commenter identified a number
of factors that would, according to the
commenter, tend to make risks higher
than presented in the RTC (e.g.. the
presence of shallow ground water, the
current lack of liners beneath existing
impoundments, the potential for changes
in population and land use patterns
leading to higher risks in the future, the
wastewater's corrosivity. and the close
proximity of each existing facility to
wetlands). All of these factors were
considered in the RTC and contribute to
EPA's concern that shallow ground
water near existing units may be
affected. However. EPA does not agree
that the RTC understates the potential
impacts associated with this
contamination, because the
concentrations of contaminants in the
wastewater are generally low. No
constituents in the wastewater were
measured in concentrations above the
subtitle C regulatory levels, and few
exceeded the highly conservative risk
screening criteria used in the RTC by
more than a factor of 10. Therefore.
although the ground-water may become
contaminated above levels of concern in
the immediate vicinity of waste
management units, contaminants are not
expected to migrate downgradient to
potential human or ecological exposure
points.
Third, new data provided in
comments appear to indicate that
shallow ground water at one of the
active facilities has been contaminated

with sulfett, total dissolved sofids
(TDS), and fluoride.* Concentrations of
sulfate and TDS in a few wells
surrounding wastewater management
units exceed upgradient concentrations
and secondary drinking water standard*
(designed to prevent an unpleasant
taste). Fluoride concentrations in the
ground .water exceed background
concentrations but do not exceed the
health-based drinking water criterion.
Contamination above the sulfate and
TDS standards appears to have
migrated at least SO meters
downgradient from the units. No
significant effect on pH has been
observed, however, even though the
very low pH of the wastewater would
appear to pose the greatest threat. In
addition, no data are available on the
concentrations of metals and other
constituents with subtitle C regulatory
levels, but any contamination by these
constituents is expected to be minor
because concentrations in the
wastewater are low, as discussed
above. No other cases of documented
damage attributable to HF acid process
wastewater are known to exist
Based on these findings, EPA
concluded that additional waste
management controls for HF acid
process wastewater might be
appropriate, and proceeded to Step 2 of
its decision making process. In this step
of the process, the Agency found that:
• Current practices at two of the three
active facilities are probably adequate
to limit contaminant release and
associated risk. One of the two manages
the wastewater in a surface
impoundment bounded by a slurry wall
and conducts ground-water monitoring.
while the other neutralizes the
wastewater prior to using it for gypsum
transport.
• It does not appear that existing
state controls adequately address the
management of this waste at all
facilities. Of the three states where
active facilities are located {LA. TX. and
KY). Louisiana appears to be most
comprehensive in its regulation of
hydrofluoric acid process wastewater.
The other two states impose less
stringent requirements, though Kentucky
recently proposed new solid waste
regulations that may address process
wasrewater more directly.
• Though the corrosivity of the
wastewater is a potential concern, it
does not appear to pose a significant
problem at the three active facilities
based on available ground-water
monitoring data. In addition, the
concentrations of RCRA Appendix VHI
constituent* in the waste are fow
enough that they ate not expected to
resoh hi exceedances of applicable
standards in ground water. Regulation
under subtitle C would also impose
significant and specific requirements
(e.g., linen, financial responsibility) that
are not appropriate given the special
status of the waste.
Based upon the combined findings of
Steps 1 and 2. EPA concludes that
regulation of process wastewater from
hydrofluoric acid production under
subtitle C is inappropriate. Although the
waste exhibits the hazardous waste
characteristic of corrosivity, the low pH
of the wastewater does not appear to
pose significant human health or
environmental hazards at the three
active facilities. Moreover, the only
constituents which were found in the
wastewater at significant levels (e.g..
sulfares, fluoride) are not listed in
appendix VIII of part 261. Thus, aside
from corrosivity, subtitle C would not
identify or list this waste as hazardous
under subtitle C. Consequently, to the
extent that stale programs are
determined to be inadequate, the
Agency plans to pursue methods within
the developing subtitle D mining wastes
program to control risks posed by this
waste. (Accordingly, EPA did not
proceed to evaluate the questions
addressed in Step 3 of its decision
making process.)
This determination differs from the
RTC's tentative recommendation
primarily because the Agency closely
reexamined the reported damage case in
response to public comments. As
outlined above, this examination
demonstrated that the damages
described in the RTC are actually
attributable to a different waste, rather
than to HF acid process wastewater.
Therefore, the primary reason for
tentatively recommending subtitle C
regulation in the RTC has been removed.
Phosphogypsum and Process
Wastewater from Phosphoric Acid
Production. The Report to Congress
considered two special wastes from
phosphoric acid production:
Phosphogypsum and process
wabtewater. EPA believes that it is
appropriate to address these two wastes
together in this regulatory
determination. Although the wastes do
not necessarily have to be co-managed.
all of the active phosphoric acid
facilities presently manage the gypsum
and wastewater together in one system.
consisting of a phosphogypsum stack
and associated impoundments.*
Therefore, it is not possible to make a
determination for one waste without, in
practice, affecting the status of the i
waste at all of the operating facihrU
addition, thoBgh the two wastes hav
distinct physical and chemical
properties, it is very difficult to attribute
environmental problems m the vicinity
of the waste management units to one
waste or the other. Moreover, given the
existing co-management of the wastes, it
is also appropriate to evaluate the two
wastes together from the standpoint of
alternative management practices and
cost/economic impacts.
In the Report to Congress, EPA
tentatively recommended Subtitle 0-
Plus regulation for both phosphogypsum
and process wastewater. Since
publishing the RTC EPA has conducted
a supplemental analysis of management
technologies and state regulations for
the two wastes, and received and
evaluated public comments on the RTC
and supplemental analysis. In addition.
in response to public comments, EPA
ha* more doseVy evaluated existing
ground-water monitoring data for the
active phosphoric acid facilities and
analyzed the potential costs associated
with the corrective action provisions in
RCRA sections 30M(u) and 3006(h). EPA
therefore reconsidered the RTC's
tentative recommendation to account for
this additional information.
AddresragStep 1 in the Agency
decision making process, which
evaluate* whether management of the
wastes pose* human health or
environmental problems, EPA made
three finding*.
First, both the gypsum and process

out of two samples of phosphogypsum
from this facility contained
concentrations of chromium that exceed
the toxicity characteristic regulatory
level, by a factor of six, on average. This
appears to be a characteristic restricted
to gypsum derived from the processing
of certain phosphate rock mined in Utah
and processed at the Rock Springs
facility. Available data indicate that the
concentrations of chromium and other
EP constituents in gypsum at facilities in
Louisiana and Florida, which process

two orders of magnitude below the
regulatory levels.
In contrast the process wastewater
routinely exhibits the hazardous waste
characteristic of corrosivity (i.e.. it has a
pH of less than 2). Out of IS facilities
with data, all process wastewater
samples examined at six facilities had a
pH less than 2 and most samples
examined at six other facilities had a pH
below 2. All of the pH values available
for the other three plants with data are
greater than or equal to 2. Process
wastewater at three out of six facilities
with data also exhibits the toxicity
characteristic. A total of 19 of 19
wastewater samples from the three
facilities contained cadmium
concentrations that exceed the
regulatory level (by a factor of four on
average), and two out of two samples
from one of the facilities also contained
chromium concentrations that exceed
the regulatory level (by a factor of two.
on average).
Second, existing practices for
managing phosphogypsum and process
wastewater appear to pose substantial
risks of environmental contamination
and impacts through the ground-water
and surface water pathways.
Considering the hydraulic head created
by gypsum stacks and process
wastewater impoundments and the net
recharge, depth to ground water, and
subsurface permeability at the 20 active
facilities, EPA believes that there is a
moderate to high potential for ground-
water contamination across the
industry. This potential for ground-water
contamination is limited significantly at
the one Wyoming facility, which has
equipped its waste management units
with synthetic liners and a seepage
collection ditch, but the units at most
other facilities are either unlined or only
lined with the clay and silt that
naturally exist in the area. EPA's
concern about potential ground-water
contamination at the 11 facilities in
Central Florida is compounded by the
presence of underlying karst in the deep
Floridan Aquifer karst is prone to form
caverns or solution cavities that can
serve as contaminant migration
pathways. Available data indicate that

either a private or public well, where
potential human exposures could occur,
within 1.600 meters (1 mile)
downgradient of the waste management
units at 14 of the 20 active facilities. In
addition. 15 of the active facilities are
located within 1,600 meters of a wetland
and 16 facilities have waste
management units within 500 meters
(less than a third of a mile) of a surface
water body where contamination could
pose ecological threats. Phosphogypsum
does not appear to pose a significant air
pathway risk. Radon emissions to the
air from gypsum stacks are controlled
under the Clean Air Act at a level
designed to ensure "acceptable" risk
within an "ample margin of safety" (see
54 FR 51654, December 15,1989).
Windblown dust releases from gypsum
stacks also appear to be effectively
precluded by the crust that forms on the
dried gypsum solids.
Third, a close examination of
available monitoring data reveals that
there are numerous cases of
documented ground-water
contamination across the industry. For
example, out of 16 facilities with data,
the phosphogypsum stacks and/or
process wastewater ponds at 13
facilities appear to have caused
groundwater contamination that
exceeds background levels and primary
(i.e.. health-based) drinking water
standards. Contamination by
constituents with toxicity characteristic
regulatory levels is seldom evident more
than 500 meters from the waste
management units, but other
contaminants with health-based limits
(gross alpha radiation, radium, and
sodium) have migrated in potentially
harmful concentrations over greater
distances. Based on a review of the
monitoring data and plant
configurations, EPA believes that
contamination above primary drinking
water standards has migrated or is
likely to migrate beyond the facility
property boundary (unless corrective
measures are implemented) at 12 of 15
facilities with data.
Based on these findings. EPA
concluded that management of
phosphogypsum and process
wastewater poses potential health and
environmental problems. Therefore, EPA
proceeded to Step 2 of its decision
making process to examine whether
more stringent regulation is necessary or
desirable. In this step. EPA found that

practices are often not adequate to limit
contaminant release and associated
risk. As discussed above, current-
management practices generally consist
of disposal or storage in large unlined
piles and ponds, typically in areas that
are conducive to ground-water
contamination,
• Current state and federal
regulations generally do not appear
adequate to control current and likely
future ground-water contamination.
Although Florida is in the process of
developing strengthened regulations, the
State presently permits the special
waste units to contaminate ground
water, usually as far as. but sometimes
beyond, the facility property boundary.
Given the intrinsic hazards of the
wastes, the widespread potential for
contaminant release and migration, and
the potential for human and ecological
exposures in the vicinity of active
facilities, EPA believes a more stringent
regulatory approach is needed.
• EPA believes that regulation under
subtitle C would impose significant and
specific requirements that are directed
at controlling the types of releases/risks
that have been documented for
phosphoric acid production wastes
across the industry.
Based on the combined findings from
Steps 1 and 2, EPA concluded that
existing management practices create
the potential for environmental
problems and that more stringent
regulation is both necessary and
desirable. EPA therefore seriously
considered subtitle C regulation for the
phosphoric acid wastes and proceeded
to Step 3 of its decision-making process
to evaluate the operational and
economic consequences of a subtitle C
determination.
In Step 3 of the decision-making
process, EPA examined the costs and
impacts of the three regulatory scenarios
examined in the RTC and the
Supplemental Analysis, and used the
insights gained thereby in deciding
whether the economic impacts of
subtitle C (or C-Minus) regulation might
cause extensive and significant
economic dislocations within the
phosphoric acid production industry.
Cost impacts were reevaluated
subsequent to release of the RTC and
were based upon an integrated
management strategy for controlling
risks posed by the two special wastes in
combination. This departure from the
Agency's initial approach was required
by new knowledge gained through
additional plant visits and analysis;
these findings are summarized in the
Supplemental Analysis and discussed
further in comment response documents.
Extensive comments received on the
Supplemental Analysis have cast doubt
upon the engineering feasibility of some
of the watte management alternatives
-------
F»aWat Renter / Vol. 5» No. 114 / Thursday, JUIM l» 199i / Rules an* Begnia4one
presented in that document.
Consequently, the Agency has based its
cost analysis in support of today's
regulatory determination on the use of
lined phosphogypsum stacks and
cooling ponds (Engineering Alternative 3
in the Supplemental Analysis). The
technology required to implement this
alternative has been amply
demonstrated (i.e., is feasible), though
the costs involved are higher than those
of some of the other alternatives
evaluated in the Supplemental Analysis.
Because EPA is not confident at present
that full subtitle C compliance is
technically feasible for existing
phosphoric acid plants, principally
because of the predicted operational
effects of the large-scale lime
neutralization required fox compliance
(the only Engineering Alternatives that
would comply with promulgated Subtitle
C Land Disposal Restrictions (LDRs) for
corrosive wastes rely on lime
treatment), the cost and impact analyses
conducted for today's notice focus
exclusively on the Subtitle C-Minus and
D-Plus scenarios.
EPA has estimated that the total
industry-wide cost of compliance with
the Subtitle C-Minus scenario (assuming
implementation of Engineering
Alternative 3) would be approximately
$465 million annually, with an additional
$15 million to $60 million required
annually for corrective action.
depending upon the analytical
assumptions employed. Estimated
annuali?.ed compliance costs for the
Subtitle D-Plus scenario are
approximately one-third lower, at about
$330 million for the industry in total:
corrective action costs under this
scenario could range from $13 million to
$48 million annually. These costs
represent from M.0 to 21.« percent of tb*
value of shipments (VOS) under Snbtitle
C-Minus. and from 6.2 to 15-2 percent of
the VOS under Subtitle D-Pkis
(excluding corrective action cost*).
depending upon the facility involved.
Costs of this magnitude exceed typical
operating margins in the affected
industry, could not be passed through.
and hence, could not be sustained over
an extended period.
As required by Section 8002(p)(7),
EPA has also conducted an analysis of
the impacts associated with the costs of
regulatory compliance Based upon the
results of this analysis, the Agency has
concluded that the costs and impacts of
regulatory compliance under th« Subtitle
C-Minus and D-Phis scenarios w«uld be
highly significant far moat phosphoric
acid facilities, witk C-Minut costs being
particularly difficult to withstand. These
costs woulid create «^>nfmMc hardship
for and threaten the centimed economic-
viability of many of (be facilities in the
industry. Consequently, the Agency has
decided that while the management of
phosphoric acid production wastes
requires additional controls, hazardous
waste controls under RCRA are too
inflexible and costly For the industry to
implement and remain economically
viable. Even a less rigorous approach
under the auspices of RCRA Subtitle D
could impose costs and impacts that the
domestic industry would find difficult to
withstand. Therefore, the Agency has
serious reservations regarding the
economic feasibility of a traditional
waste management program designed
within the contours of the RCRA statute.
Given these facts and the need for
action to address the risks posed by
phosphoric acid production processes
and associated wastes. EPA believes
that a different approach is required.
The Agency has therefore developed a
two-pronged approach to address these
wastes. First, the Agency will rely upon
existing authorities under RCRA Section
7003 and CERCLA Section 106 to
respond effectively to emergency
situations that arise. In addition. EPA
will accelerate the collection of facility-
specific information, consider the risks
posed by these facilities, and take
appropriate action to contain or
stabilize wastes at facilities that present
a risk to human health and the
environment In this manner, EPA
believes that it can respond
appropriately to any problems that arise
while developing a program that is both
adequately protective of human health
and the environment and economically
feasible and achievable for affected
industry.
Second. EPA believes that a
regulatory program specifically designed
to address the complex issues
associated with phosphoric acid
industry special wastes can be
developed under authorities affbfded by
the Toxic Substances Control Act
(TSCA). Like RCRA. TSCA providas a
mechanism to address threats posed to
human health and the environment and,
unlike RCRA Subtitle C. does not
contain prescriptive requirements.
TSCA provides the additional and
significant advantage of being broader
in scope, and explicitly allows EPA to
address various parts of the production
and waste generation process itself.
Therefore. EPA plans to proceed with
examination of this problem under
TSCA to consider how to develop •
program that will address phosphoric
acid production practices and processes
to reduce the risks posed by
phospbogypsura and process
wastewater.
The TSCA regulatory inrestigation
already underway vrifl focus on
developing risk management strategy
to reduce or eliminate risks posed by
phosphoric acid production wastes. EPA
is evaluating the chemicals and the
processes involved in phosphoric acid
production and the resulting wastes to
determine how TSCA authorities can
best be used to reduce the toxicity and/
or volume of these wastes. The Agency
will analyze the efficacy and feasibility
of some of the alternatives to current
practices that were described i:i the
Supplemental Analysis, wilh sn
emphasis on developing so-jnd methods
(in both a technical and economic sense)
of reducing the toxicity and/or the
volume of the special wastes. EPA will
assess pollution prevention
opportunities based on a phosphoric
acid life-cycle analysis, the
Supplemental Analysis, and other
information obtained during the TSCA
investigation. The investigation will also
address the risk reduction potential and
associated costs for identified regulatory
options, such as restrictions on
manufacturing, processing, or disposal.
Depending on the results of this
assessment site specific risk reduction
strategies may be considered as most
appropriate. As specific wastes or
toxicity reduction techniques are {
identified. EPA will work with the
industry to implement the most
promising alternatives as quickly as
possible. EPA believes that by
developing a tailored program under
TSCA. the Agency will be able to more
fufly explore, promote, and enforce
several promising pollution prevention
and/or source reduction ideas (e.g., •
more efficient raw product filtration,
fluosinac acid recovery) tiian would be
possible under a RCRA program.
In addition, EPA plans to further
explore and evaluate containment
strategies of vaxioas kinds, so that
whatever wastes are generated will not
resmh in contaminant releases to the
environment. If information obtained or
findings developed during the TSCA
investigation are such that RCRA could
better handle this matter, the Agency
will revisit today's regulatory
determination, and determine whether
subtitle C regulation of the phosphoric
acid special wastes remains
inappropriate.
IV. Dvcnmn TB Postpone Conside
of a Possible Ban an Elemental

In the RTC, EPA found that the-
radionuclide content and potential

radiation risk » a concern for slag Cram
elemental phosphorus production. The
primary basis for this finding was EPA's
Idaho Radionuclide Study,11 which
estimated that average life-time cancer
risks range from 4xl(T4 to 1x10"' in
Soda Springs and Pocatello, Idaho as a
result of the use of elemental
phosphorus slag in a wide range of off-
site construction applications. Based on
these findings, EPA stated in the RTC
that it planned to use the authority of
RCRA section 3001(b)(3}(B)(iii) to ban
the use of the slag in construction and/
or land reclamation when the Agency
issued its regulatory determination for
mineral processing wastes. EPA
solicited comments on the appropriate
regulatory language that should be used
and how such a ban should be
implemented.
In response, five commenters
questioned the validity of the Idaho
Radionuclide Study. The commenters
argued that the study was not conducted
according to required procedures, has
not been sufficiently peer-reviewed,
contradicts epidemic-logical studies that
show that cancer risks in Idaho are low,
and suffers from several technical flaws.
For example, according to the
commenters, the data collection
methodology was inadequate to support
valid risk estimation, the study relies on
a zero threshold low-dose risk model
that is not supported by experimental
evidence, and the study relies on aerial
radiation measurements that exaggerate
actual radiation levels. The commenters
argued, therefore, that the Idaho study
cannot be used as a basis for a decision
to ban off-site uses of the slag.
Since the release of the RTC, the
Idaho Radionuclide Study and
supporting data have been distributed
for review by industry, EPA's Science
Advisory Board (SAB), and the Ageacy
for Toxic Substances and Disease
Registry. A public hearing on the study
was also held in Soda Springs, ID OR
August 21,1990. Because of the concern*
raised, EPA has postponed its final
determination on the validity of the
itudy's conclusions until the Agency
decides how to incorporate SAB'S
'.findings and after the Agency's review
of information provided at the public
hearing is completed. In addition, the
Agency is postponing its consideration
of a possible ban on elemental
phosphorus slag utilization until it
completes its review of the technical
basis for such an action. EPA will
propose a supplemental notice at the
appropriate time.

V. Regulatory Flexibility Analysis
The Regulatory Flexibility Act (RFAJ
of 1980 (Pub. L 96-354), which amends
the Administrative Procedures Act,
requires Federal regulatory agencies to
consider "small entities" throughout the
regulatory process. The RFA requires in
section 603 an initial screening analysis
to be performed to determine whether a
substantial number of small entities will
be significantly affected by a regulation.
If so, regulatory alternatives that
eliminate or mitigate the impacts must
be considered.
EPA conducted a detailed analysis of
the facilities and companies that
generate the 20 special wastes from
mineral processing during the
preparation of the Report to Congress.
The Agency established at that time that
no companies that meet the definition of
"small business" generate any of the
special mineral processing wastes. Also,
EPA has not received any information in
public comment on the Report that
would contradict this finding, and
therefore concludes that today's action
will not adversely affect small mineral
processing companies. Consequently, an
explicit Regulatory Flexibility Analysis
is not required.
VI. Agency Initiatives
To follow up on the findings that have
resulted in today's regulatory
determination, EPA plans to continue
several initiatives that directly relate to
some of the mineral processing wastes
addressed in this regulatory
determination. These initiatives include
the following four activities:
(1) Evaluation of the radiation
exposures and risks associated with the
off-site use of elemental phosphorus
slag:
(2) Review of hazards posed by
wastes containing diffuse naturally
occurring radioactive material (NORM);
(3) development of a management
program under RCRA Subtitle D for
mineral extraction and beneficiatkm
wastes: and
(4) Development of a program under
TSCA addressing the phosphoric acid
industry.
As discussed in section IV of this
preamble, in April 1980, EPA released
the Idaho Radionuclide Study, which
provided an assessment of the direct
radiation exposures and risks
associated with the use of elemental
phosphorus slag in construction in Sod*
Springs and Pocatello, Idaho. A pubfic
hearing on the study was held in Soda
Springs. ID on August 21.1990. EPA has
also requested its Science Advisory
Board (SAB) and other scientific
organizations to review the study's
underlying data, methodology, and
conclusions. The SAB is scheduled to
issue its findings this year. When
available, EPA wiB review these
findings together with other scientific
and public inputs to define needs for
further study. Final conclusion* from
this study will be used to help evaluate
the need for any added controls on the
off-site use of elemental phosphorus
slag.
In a separate study, EPA is presently
evaluating the characteristics, risks, and
regulatory control options under TSCA
for diffuse NORM wastes. The scope of
this study is much broader than the
Idaho Radionuclide Study, and includes
phosphate and elemental phosphorus
wastes, metal mining and mineral
processing wastes (including wastes
from bauxite and aluminum, copper,
zinc, tin. titanium, and zirconium and
hafnium processing), and a variety of
other wastes (e.g* coal ash, oil and gas
production scale, water treatment
sludges, and certain consumer items).
The purpose of the study is to determine
whether the routine management of
these wastes pose a sufficient
radiological hazard to warrant
additional regulatory controls. EPA
plans to complete the study in the
summer of 1991, at which time the
Agency will begin to evaluate whether
any added controls are necessary to
limit the radiation hazards, what
authorities exist for such controls, and
what the form and substance of a
NORM waste program might be. As
appropriate, EPA wiQ evaluate
authorities and opportunities to address
NORM wastes under RCRA, the Toxic
Substances Control Act. and other
programs.
EPA is in the process of developing a
RCRA Subtitle D program for mineral
extraction and beneficiation wastes.
EPA plans to include those mineral
processing wastes determined here to
warrant regulation under subtitle D
under the regulatory "umbrella" for
extraction and beneficiation wastes,
making it the extraction, beneficiation.
and mineral processing wastes program.
As the development of this program
proceeds, the Agency may find it
necessary to control certain mineral
processing wastes, such as waste acids,
that have little in common with the
majority of extinction and beneficiation
wastes under • separate regulatory
program^

determination for the phosphoric add
wastes, EPA pUaa to proceed with an

and processes to reduce the risks posed
by these two wastes.

Appendix A—Analysis of and Response
to Public Comments on the Report to
Congress
EPA received numerous public
comments on the Report to Congress,
including comments on the overall
methodology used to evaluate the eight
study factors and comments on the
specific analysis and discussion of each
of the 20 wastes. All of the comments
are available for inspection in Docket
No. F-90-RMPA-FFFFF. EPA has
carefully considered each of these
comments in developing this regulatory
determination and includes in this
appendix responses to certain major
comments that have a particularly
significant bearing on the Agency's final
determination. All other comments and
detailed responses are included in a
supporting comment response
background document, available for
inspection in the RCRA docket.
/. Report to Congress Methodology
The Agency received a number of
comments on the Report's scope (i.e.. the
particular wastes studied) as well as the
approach that EPA used to evaluate five
of the study factors: (1) Waste
characteristics, generation, and current
management practices; (2) potential
danger to human health and the
environment; (3) documented danger to
human health and the environment; (4)
compliance costs; and (5) economic
impacts. Commenters did not raise
significant methodological issues
concerning the Agency's evaluation of
Federal and State waste management
controls or waste management
alternatives and potential utilization.
A. Scope
Several commenters took exception to
the Report's overall scope, with some
stating that the scope was too narrow
and some stating that the scope was too
broad. The commenters that argued that
the scope was too narrow said that EPA
improperly narrowed the scope of the
mining waste exclusion, leaving several
mineral processing wastes potentially
subject to subtitle C regulation when
they should have been studied further in
the Report to Congress. For example,
one commenter said that certain wastes
that exhibit a hazardous waste
characteristic, such as coal tar wastes
from historic town gas manufacturing.
constituted exempt mineral processing
wastes and should have been studied in
the Report. The commenters that
believed the scope was too broad said
that EPA wrongly studied materials that
are not solid wastes and thus not
subject to RCRA regulation, such as
some slags.
EPA believes the argument that the
scope of the Report was too narrow is
not an issue pertaining to the Report to
Congress, but rather pertains to the
scope of the Agency's final rulemakings
interpreting the scope of the exclusion
for mineral processing wastes. As EPA
explained in the preambles to the rules
as well as the Report to Congress, two
final rules established the scope of the
exemption for mineral processing, and •
EPA did not solicit further comment on
this issue in the RTC. EPA also notee
that the coal tar wastes mentioned in
the comment are no longer generated
(the last plant that manufactured gas for
municipal use using coal closed in the
1970*8) in high volumes (if they ever
were), and the Bevill Amendment
applies only to currently generate
waste and historical stockpiles of
currently generated waste. Mor
the coal tar wastes remaining from
historic town gas manufacturing are
substantially different from the coal gas
wastes studied in the Report to
Congress, as the coal tar wastes have a
different chemical makeup and were
generated by different processes.
With respect to the argument that the
scope of the Report is too broad, EPA
acknowledges that some of the
materials examined in the Report are
not always solid wastes, depending on
how they are managed in particular
instances. In fact, if they are not defined
as solid wastes under EPA's regulations.
the Agency agrees that regulation under
RCRA is not appropriate. However, the
Agency believes that all of the materials
examined are managed as a solid waste.
as defined by RCRA regulations, at least
part of the time at some facilities.
Therefore, all of these wastes were
appropriate for study in the mineral
processing report.
B. Waste Characteristics. Generation,
and Current Management Practices
One commenter argued that EPA's
consideration of waste characteristics in
the RTC did not recognize the
in composition of a given
one facility to the next. Accordinthe
commenter, this variability provides
support for a determination that subtitle
C regulation is unwarranted because
regulation under other state and federal
authorities provides the flexibility
necessary to address the geographic
variability in waste characteristics
(which subtitle C does not). For
example, data for phosphogypsum and
process wastewater from phosphate
rock processing clearly demonstrate,
according to the commenter, the
variability of characteristics of these
wastes and the relationship between
that variability and the geographic
origin of the phosphate rock being
processed. The commenter went on to
contend that the RTC used waste
characterization data only to determine
whether a waste contains constituents
at concentrations of potential concern.
ignoring the critical aspect of geographic
variability.
EPA disagrees with this comment
Waste characteristics and the
variability in chemical concentrations
from one facility to the next were
critical elements in the risk and cost
analyses, as well as in the Agen
final decision making. Specific
variability in waste compositioi
-------
Federal Regular / Vol. 5fr No. 114 / Thuryjay. June 13, 1991 / Rules and Regulations 27319
explicitly highlighted in the analysis of
each waste's intrinsic hazard, and the
facilities that were examined in the cost
and economic impact portions of the
analysis were selected as a function of
whether their wastes exhibit a
hazardous waste characteristic. If
subtitle C regulation for a given waste
warranted serious consideration based
on an analysis of the study factors, EPA
closely examined on a facility-by-
facility basis the frequency and
magnitude with which the waste
exhibits a hazardous waste
characteristic in order to reach a final
regulatory determination.
C. Potential Danger to Human Health
and the Environment
1. Leaching Procedures. Four
commenters addressed the
appropriateness of different laboratory
leach tests used to measure contaminant
concentrations in leachate from mineral
processing waste samples. Three of the
commenters objected to the RTCs use
of data generated from the Extraction
Procedure (EP) leach test. These
commenters stated that EP leachate
concentrations overestimate actual
leachate concentrations because the EP
test mimics an implausible
mismanagement scenario in which
mineral processing wastes are co-
disposed with municipal solid waste in a
municipal landfill and exposed to an
organic leaching medium. In general,
these commenters believed that
analytical results from a distilled water
leaching procedure or the Synthetic
Precipitation Leaching Procedure (SPLP)
would provide a more realistic
assessment of the teachability of metals
from mineral processing wastes under
actual field conditions. In contrast
another commenter suggested that use
of the EP leach test data is reasonable
because, among other reasons, co-
disposal with municipal wastes cannot
be ruled out for some mineral processing
wastes that are disposed off-site, and
because at the time the RTC was being
prepared, the EP leach test was the
required procedure for determining
whether a mineral processing waste
would be regulated as EP toxic if the
Bevill exemption was removed.
The Agency believes that the RTCs
use of EP leach test data for mineral
processing waste characterization and
risk assessment is reasonable for three
main reasons. First use of the EP
leachate data is a reasonably
conservative approach. While several
constituents were found to be present in
higher concentrations in EP leachate
than SPLP leacnate for some samples
that were tested naiag both procedures.
results for the two test* are often similar
(and for liquid wastes, they are-identical
since liquids are not leached, but simply
compared directly to the appropriate
regulatory concentration levels). There
are also cases where EP leachate
concentrations were found to be less
than SPLP leachate concentrations. For
example, the results of an EPA study '
analyzing the validity of the SPLP test
showed that the SPLP test has been
shown on occasion to underestimate the
amount of teachable lead in a sample.2
Other constituents that are commonly
present in higher concentrations in EP
leachate than SPLP leachate include
iron, zinc, aluminum, cadmium, copper,
and nickel. In contrast arsenic,
vanadium, molybdenum, and barium are
commonly found in higher
concentrations in SPLP leachate than EP
leachate. In addition to the fact that EP
leachate concentrations appear
reasonably conservative relative to the
SPLP concentrations, the Agency
believes use of the EP leachate data is
reasonable because mineral processing
wastes may be plausibly mismanaged in
a municipal landfill in certain cases. For
example, lead slag from one of the
primary lead processing plants, and
steel (basic oxygen furnace and open
hearth furnace) air pollution control
dust/sludge from one plant are presently
shipped off-site for disposal in a
municipal landfill. Given the existing
regulatory regime, it is not inconceivable
that other mineral processing wastes
from other facilities could be disposed in
a similar manner in the future.
Second, as noted by one of the
commenters, the EP leach test at the
time the RTC was being prepared was
the legally required procedure for
determining whether the mineral
processing wastes under study exhibit
the hazardous waste characteristic of EP
toxicity. The test that has replaced the
EP test, the Toxicity Characteristic
Leaching Procedure, assumes the same
mismanagement scenario and will also
be used to determine the toxicity of
wastes for regulatory purposes.
Third, the vast majority of available
leachate data for mineral processing
wastes are from EP leach tests. The
amount of data from other laboratory
leach tests or from samples of actual

leachate collected in the field is
insufficient to support a comprehensive
evaluation.
The Agency recognizes that there are
some uncertainties associated with
using EP leachate data to estimate the
concentrations of metals in leachate
generated from the mineral processing
wastes as they are currently managed.
As a result the differences between
measured EP and SPLP leachate
concentrations were factored into the
Agency's decision making for this
regulatory determination. Also. EPA
acknowledges that the RTC's use of EP
leachate data differs from the approach
used in the Agency's previous
rulemakings on mineral processing
wastes (reinterpreting the scope of the
Mining Waste Exclusion), but believes
the reasons outlined above provide a
sound basis for using the EP data in the
analysis leading to the regulatory
determination. In the previous
rulemakings, the Agency used limited
SPLP data in order to establish which
wastes qualified as "low hazard" and
thus were eligible for detailed study in
the RTC (I.e., use of the SPLP data was a
reasonable approach for selecting the
wastes to be studies, because wastes
that exhibit hazardous characteristics
under the SPLP test are clearly not low
hazard). For purposes of actually
conducting a risk assessment, however,
relying primarily on the EP leachate
data is a reasonable, though more
conservative approach. The overall
conservativeness of EPA's risk
assessment is discussed further below.
2. Overall Conservativeness. Five
commenters stated that the risk
assessment methodology in general
relies on overly conservative
assumptions that grossly overestimate
risk and ignore contradictory real-life
information. The commenters said the
risk screening criteria used to evaluate
the intrinsic hazard of each waste
stream's composition are ultra-
conservative, as they are based on
worst-case assumptions regarding an
unbroken chain of events that allow
contaminant release, migration through
the environment and exposure to
receptors.
While the Agency agrees that there
are elements of the risk assessment
methodology that tend to overestimate
actual risks, these overestimates are
offset somewhat by other elements of
the methodology that tend to
underestimate actual risks. The Agency
acknowledges that most of the risk
screening criteria are conservative, as
stated throughout the RTC. However.
the Agency used these criteria or.ly for
the purpose of analyzing the intrinsic
-------
27320 Federal Register / Vol. 56. No. 114 / Thursday. June 13. 1991 / Rules and Regulations
hazard of each waste stream. EPA
interpreted an exceedance of the criteria
only as an indication that the risks of a
given waste should be evaluated in
more detail, not by itself as proof that
the waste poses a significant risk. If a
waste contained constituents in
concentrations above the screening
criteria, the analysis was supplemented
with additional evaluation of conditions
at actual facilities, and then further, if
this evaluation indicated that there were
potential problems, the Agency
conducted risk modeling in order to
develop final risk conclusions. The RTC
then proceeded to evaluate the risk
conclusions together with the damage
case conclusions before reaching an
overall finding on the hazards
associated with each waste.
Overall. EPA believes that the risk
assessment, while conservative, was
reasonable in that EPA factored the
uncertainties created by key
assumptions in the risk assessment
methodology into the regulatory
decision making process for each waste
stream. The approach that EPA used to
evaluate potential human health and
environmental problems is outlined in
section II of this preamble and applied
in section ID, which presents the
rationale for the final regulatory
determination for specific wastes.
3. Modeling inadequacies. One
commenter argued that the Agency's
risk modeling was inadequate and
significantly underestimated risks
because it did not adequately consider a
number of specific factors. Important
factors that the commenter alleged were
left out or considered incorrectly include
site-specific soil-water distribution
coefficients (Kd's). the transport of
metals in ground water by colloids,
metal-organic complexing during
ground-water transport ground-water
flow through karat terrains, storm
events, evaporation and subsequent
concentration of metals in small surface
water bodies, and the transport of
contaminated storm-water run-off to
surface water bodies.
In general, EPA acknowledges these
modeling limitations but.believea most
of them were unavoidable, forced in part
by necessary limitations in the scope/
complexity of the risk assessment, as
well as by limitations in the state of
ground-water modeling as a science. For
example, the Agency agrees that Kd
values are highly site-specific, but
believes that modeling each site using
actual Kd's would have required
prohibitively extensive field
measurements and verification. As a
result, the Agency used the next best
approach—EPA used its best
professional judgment to select
representative Kd values for each site
and each contaminant, based on a
review of data in the literature and an
examination of available data on the
soil composition at each site. In
addition, with the possible exception of
a few experimental models, the Agency
is unaware of any reliable techniques
for modeling the migration of colloids or
the flow of ground water through karst.
Overall, the Agency believes that its risk
modeling approach accounts for the
factors noted by the commenter in the
best way possible, considering the
study's time limitations. When
significant factors could not be
considered in the quantitative modeling
exercise, they were considered in a
qualitative manner so as to not
compromise the overall completeness of
the risk analysis.
4. Lack of Consideration of Off-Site
Use/Disposal and Future Changes. One
commenter argued that the risk
assessment was deficient because it did
not consider the risks associated with
off-site use or disposal of the mineral
processing wastes. This same
commenter said the risk assessment is
also fundamentally flawed because it
analyzes risks only in terms of existing
conditions at each facility that generates
the mineral processing wastes, not
accounting for possible future changes
in water use patterns or population
distributions.
While the Agency acknowledges that
it did not rigorously model the risks
associated with off-site use/disposal or
possible future locations of new
facilities, it disagrees that the RTC did
not consider these factors.3 Based on a
review of the past disposal practices
and potential utilization of each waste.
only about half of the mineral
processing wastes are candidates for
off-site use or disposal, including copper
slag, elemental phosphorus slag, all four
of the ferrous metal production wastes.
fluorogypsum, lead slag,
phosphogypsum, and zinc slag. In the
case of elemental phosphorus slag, the
RTC relied on monitoring and risk
modeling conducted by EPA's Office of
Radiation Programs to evaluate the
potential radiation hazards associated
with off-site uses: as discussed in
section VI of this preamble, EPA is in
the process of re-examining the validity
of this off-site modeling for elemental
phosphorus slag. For the other wastes.
• A* diicuiMd elsewhere. EPA did examine
potential changes in exposure scenarios •« axiiting
facilities. For example, iht Agency'* riik "•~<«lii^
examined potential groundwater expotun points •!
location* closer lo the facility than known current
well locations (e.g.. at the facility boundary).
EPA evaluated the observed and
potential hazards associated with off-
site use or disposal in the context of the
wastes' damage case record and
intrinsic hazard analysis, and factoij
the results of this evaluation into I
overall hazard findings in each waste-
specific chapter of the RTC. For
example, before reaching conclusions
about the hazards posed by iron blast
furnace slag, a waste that has been
shipped off-site for disposal and a
variety of uses for decades. EPA
searched for and evaluated any
evidence of environmental damage
caused by the off-site management
practices. The conservative risk
screening criteria used to evaluate each
waste's intrinsic toxicity also were
developed using hypothetical scenarios
that might occur if the wastes were
mismanaged (e.g.. scenarios in which an
inactive waste pile is not closed or
maintained and people are allowed to
come into direct contact with the waste).
Therefore, the Agency believes that both
off-site activities and possible future
changes have been accounted for in the
overall hazard conclusion for each
waste stream. EPA also notes, however.
that, as a general matter, the use of site-
specific risk modeling and evaluation is
appropriate for high-volume special
wastes which are typically managed on-
site.
S. Treatment of Radionuclides inl
Report to Congress. One comments
claimed that EPA's treatment of
radionuclides is different with respect to
the four wastes tentatively proposed for
removal from the Mining Waste
Exclusion and the sixteen other wastes.
The commenter argued that EPA has
determined that some radionuclide risk
exists for some of the sixteen wastes but
instead of recommending subtitle C
regulation, EPA merely expressed that it
plans to further investigate the potential
for exposure and associated radiation
risk. This commenter added that if
further investigation is warranted before
regulatory action is taken on some
wastes, the same principle should apply
to all the waste*.
EPA could not evaluate the risks
associated with radioactive constituents
for all of the wastes studied in the RTC
because the necessary data were not
available. In addition, there presently
are no controls for risks from
radioactive materials under RCRA
subtitle C, as there is not • hazardous
waste characteristic test for
radioactivity and no radionuclides or
radioactivity levels are listed in
appendix VIII to 40 CFR part 261
(Hazardous Constituents). As a i
concerns about residual radioacrii
-------
Federal Register / VoL 5Q».Na. 114 / Thursday, June 13, 1981 / Rule* and Regulations 27321
would not be resolved by removal of the
Mining Waste Exclusion, because such
an action would not result in subtitle C
regulation unless the waste exhibits a
RCRA hazardous characteristic.
To the extent that data were available
on the radionuclide concentration in
various wastes, EPA believes that it
evaluated the data and made final
regulatory determinations for the wastes
in a consistent manner. That is. EPA
uniformly compared available
radionuclide concentration data for the
wastes to risk screening criteria and
developed conclusions on the intrinsic
hazard of the wastes accordingly. The
Agency then evaluated potential
radiation risk as an element in the
overall risk assessment for each waste.
and combined the risk assessment
conclusions with the other RCRA
section 8002(p) study factors in
accordance with the decision making
methodology outlined in section 0 of
this preamble in order to reach a final
regulatory determination. Therefore,
radiation risk was but one element in an
overall evaluation process, and EPA
consistently followed that process to
reach appropriate determinations for
each waste. To the extent that
radioactivity appears to be a concern for
a given waste. EPA believes that
potential radiation risks should be
addressed along with the waste's other
potential threats within the regulatory
framework determined to be appropriate
(subtitle D in all cases). In addition, EPA
is examining potential radiation risks
associated with these and other
materials in studies currently underway.
D. Documented Danger to Human
Health and the Environment
One commenter contends that many
of the damage cases cited in the RTC
are not attributable to Bevill processing
wastes. The commenter also stated that
other damage cases cited by EPA
resulted from historical management
practices that have long since been
discontinued by the mineral processing
industry. A number of commenters made
this assertion regarding specific mineral
commodity sectors and wastes as well.
The Agency reexamined the RTC data
and evaluated the information submitted
in comments and eliminated some of the
damage cases covered in the RTC for
the purpose of this regulatory
determination (see the comment-
response background document in the
docket for details). For example. EPA
has eliminated the damage cases for
lead slag at the ASARCO facility in East
Helena. MT and for hydrofluoric acid
process wastewater at the Allied facility
in Geismar. LA because available
information indicates that the
contamination documented in the RTC
is attributable to other wastes.
Furthermore, as discussed in the RTC.
inclusion in the RTC of documented
contaminant releases to the
environment due to discontinued waste
management practices does not
necessarily demonstrate that releases
from current management practices will
occur. The Agency believes, however.
that damage case information on past
waste management practices is useful in
demonstrating the potential for
environmental and human health
impacts, for two primary reasons. First
these damage cases provide information
on combinations of management
practices and site conditions that have
resulted in environmental problems.
which is useful for anticipating and
avoiding future problems. Second,
damage cases associated with past
practices, like those associated with
ongoing practices, are useful in
demonstrating the kinds of impacts that
can result when hazardous constituents
are released from the wastes. If damage
case information on past waste
management practices was available,
EPA evaluated the particular
circumstances involved to determine if
the case represents conditions that are
likely to exist today. If. in EPA's
judgment a historical damage case did
not apply to current management
practices, it was used to supplement the
risk conclusions in the sense that it
could demonstrate how problems can
occur in mismanagement scenarios, but
it was not given the full status of a
damage case in making the regulatory
determination. However, if a historical
damage case was found to represent
today's management practices, it was
considered equally with any damage
cases for current management practices
in developing the regulatory
determination.
One commenter claimed that the
Agency did not meet the standard set by
Congress that damage cases should
relate to the individual waste stream
being studied. The commenter added
that although relating damage to a
specific stream may be difficult it is
essential if an analysis is to be
meaningful.
EPA disagrees with this comment As
mentioned previously, the Agency
reexamined the RTC data and evaluated
the information submitted in comments
and eliminated some of the damage
cases covered in the RTC because the
damages could not be attributed to a
given waste stream being studied. In
some of the cases that were retained for
the purpose of this regulatory •
determination attribution to a sole
waste stream was not possible, because
wastes were co-managed, for example.
However, the Agency believes that at
least one of the special wastes being
studied was contributing to the damages
described in cases used for the
regulatory determination. This view is
based on EPA's review of available data
on waste management practices and site
conditions as reflected in state or EPA
regional regulatory files.
One commenter argued that contrary
to the Agency's position, the absence of
damage cases is not a reliable indicator
of the absence of potential hazard from
the wastes studied in the Report. The
commenter stated that the lack of
damage cases can be attributed to two
factors: Deficiencies and flaws in EPA's
methodology for identifying damage
cases, and inadequacies within state
programs for identifying damage cases.
The Agency has reviewed these
comments and maintains the view that
its damage case investigation effort was
comprehensive and thorough. Many
sources were utilized to obtain
information on facilities, including the
National Priorities Ust (NPL) and other
lists; federal, state, and local regulatory
agencies; public interest or citizen's
groups; and professional and trade
associations. In addition. EPA followed
up on general and specific examples
cited in comments and has not found
any additional damage cases. For
example, EPA has reviewed the
evidence suggested by one commenter
linking observed damage* to forroua
metal production wastes, and concludes
that any such damages are not
attributable to any of the four ferrous
metal production wastes studied in the
Report The Agency acknowledges that
although damages may have occurred at
some facilities not identified in the
Report documentation of these damages
was not available or non-existent. This
is precisely why the RTCs findings
about the hazards of each waste stream
are based on both an analysis of
damage cases and risks in the absence
of any known damages. Moreover, EPA
believes that the lack of documented
damages for a given waste stream does
not necessarily signify a lack of hazard
from that waste stream, but believes
that the attribution of damage cases to a
waste stream is the most concrete
evidence of such a hazard,
E. Estimation of Compliance Costs
1. Incorrect Coat Estimates. Several
commenters claimed that EPA had
seriously underestimated the total
compliance costs associated with
subtitle C regulations by failing to
consider several pertinent elements.
-------
27322
Federrf Register / Vol. 59, No. 114 / Thm-aday, June 13, 1991 / Rules and Regdations
including: The cumulative financial
impact of federal and state regulation*
(including the recent Bevill
rulemakings}; hydrogeological
investigations that may include the
construction of systems of ground-water
monitoring wells; location requirements
at facilities within a 100-year flood
plain; land disposal restriction
requirements: neutralization; recycling;
remedial work to control releases; and
closure activities. One commenter, on
the other hand, asserted that EPA
overstated the cost associated with
compliance by assuming that more
facilities exhibit hazardous waste
characteristics than are indicated by
available data. For example, the
commenter stated that the Agency
incorrectly assumed that wastewater at
every facility would be regulated as
hazardous, even though the wastewater
may not actually exhibit hazardous
waste characteristics at each operating
plant.
The Agency generally disagrees with
those commenters who argued that EPA
underestimated compliance costs
associated with subtitle C regulation. As
part of its analysis, EPA did, in fact,
address many of the cited compliance
cost elements. En the Report to Congress.
EPA accounted for ground-water
monitoring systems, neutralization of
wastes, location standards, land
disposal restrictions (in some cases),
and closure requirements. The
cumulative impact of previous
rulemakmgs is not relevant to the issue
of whether the special mineral
processing wastes studied in the Report
to Congress can be managed under
RCRA subtitle C without excessive
additional costs being incurred by the
regulated community. That is, the costs
and impacts of regulating non-special
mineral processing wastes under
subtitle C have no relevance to today's
regulatory determination. EPA
acknowledges that, at certain facilities.
corrective action requirements could
result in potentially significant costs for
some wastes and, thus, has given further
consideration to the associated costs
(further discussion of this issoe is
presented below).
On the other hand. EPA acknowledges
that compliance costs may be overstated
in certain instances in which wastes
were assumed to exhibit a hazardous
characteristic when in fact they may
not. The Agency used this conservative
assumption to overcome data limitations
(i.e.. a lack of EP-toxicity test data for
some facilities) and to demonstrate the
estimated magnitude of compliance
uosts at potentially affected facilities.
While actual impacts may be less
widely distributed. EPA believes that
the approach employed was a
reasonable way of demonstrating
potential impacts to industry under
subtitle C, as contemplated by the Bevill
Amendment. In addition, the assumption
of hazardousness at all facilities and the
associated cost estimates did not affect
the regulatory determination in a
meaningful way (as discussed further
below).
2. Corrective Action Costs. Several
commenters complained that EPA failed
to consider the appropriate costs
associated with corrective action. Many
of these commenters stated that by
ignoring corrective action requirements
under RCRA sections 3004(u) and
3008{h). EPA was failing to fulfill its
statutory obligation under the Bevill
Amendment, which requires EPA to
study the costs of regulating Bevill
wastes under subtitle C. A few of these
commenters recommended that EPA
revise its cost estimates to reflect
necessary corrective actioa One of
these commenters also indicated that
EPA has the information required to
determine at least the range of likely
corrective action costs.
In response to these comments. EPA
has analyzed corrective action issues in
further detail and estimated corrective
action costs at certain facilities. EPA
focused this analysis on only those
wastes for which corrective action costs
might influence the final regulatory
determination: Phosphogypsum and
process wastewater from phosphoric
acid production. These are the only
wastes for which application of EPA's
decision making methodology required
EPA to consider potential regulatory
compliance costs. If cost had been a
factor in the decision for the other 1,8
wastes, inclusion of corrective action
costs would only have added support to
the Agency's determination not to
regulate these 18 wastes under subtitle
C.
EPA's corrective action analysis
reflects the probable response to the
predominant source and type of
contamination that has been observed
at phosphoric acid facilities, namely
contamination of underlying ground-
water aquifers by the routine operation
of gypsum stack-cooling pond
complexes. The response strategy
examined by EPA involves the
installation of a ground-water
containment system consisting of
extraction wells (in some cases
supplemented by a slurry wall) around
the entire stack-pond complex. In this
manner, contaminants entering the
subsurface would be removed, thereby
preventing them from further
contaminating the affected aquifer(s).
This strategy assumes that over time,
existing contaminants present in
ground-water system would be dilut^
and/or attenuated to below MCLs (c
m part to the gradual rise in ground-
water pH caused by eliminating the
continuous introduction of acidic
process wastewater to an unlined slack/
pond system), thereby obviating the
need for active aquifer remediation
activities over the entire contaminated
area. The Agency has identified the
facilities that would likely experience
corrective action (under either a
modified subtitle C or D situation), and
has estimated the costs of implementing
the response strategy described here.
Details regarding EPA's methodology
and the results of the analysis are
provided in a Technical Background
Document that they may be found in the
supporting docket for today's notice. In
general corrective action costs are
relatively modest «, contrary to the
unsupported statements of many
commenters, and comprise
approximately tea percent of total
annualized compliance costs at the
individual facility level.
3. Land Disposal Restrictions Costs.
EPA received several comments stating
that the Agency did not include specific
estimates of cosU associated with lac
disposal restrictions as they would^
apply to mineral processing waste I
and sectors. One of these commenterT"
argued that hi the "third third" rule. EPA
designates stabilization as BOAT for
treating metal-bearing wastes, yet the
Agency does not include stabilization
costs in its RTC cost estimates. This
commenter further argued that EPA
should have considered the additional
on- and off-site disposal costs
associated with acquiring additional
land for disposal on-site and
transportation costs to a remote
location.
Contrary to these assertions. EPA did
evaluate land disposal restrictions costs
for some of the wastes addressed in the
Report to Congress, including sludges.
These materials were assumed to be
cement stabilized prior to disposal in
subtitle C landfills. Moreover, the
resulting increase in the volume of the
wastes in question was explicitly
factored into EPA's analysis, by
calculating the incremental landfill
volume required, adjusting the landfill

design accordingly, and calculating the
total cost of the necessary land disposal
unit(s) for the wastes in question. In
conducting the supplementary analysis
of the phosphoric acid sector, the
Agency also factored land disposal
restriction costs (lime treatment) into
the total costs for phosphogypsum
disposal.
BDATs were not applied, and costs,
therefore, were not calculated, for
copper, lead, and zinc slags because of
an assumption that slags, when
generated, are similar to wastes that
have been treated by vitrification (a
BOAT). For this reason, stabilization
was presumed to be an unnecessary
management method for these wastes.
(If stabilization is required, costs would
increase, but this would not have
affected the Agency's regulatory
determination.) Transportation costs
were not factored in for on-site
management because data in EPA's
possession and personal observations
made during site visits to a substantial
number of the facilities considered in
the Report demonstrate that many, if not
most, potentially affected facilities own
land of adequate size contiguous with or
close to their existing waste
management units to construct new
units of sufficient capacity.
4. Costs Associated With Replacing
Waste Management Units. Some
commenters argued that EPA failed to
consider the costs associated with
replacing subtitle C hazardous waste
disposal facilities in the future (i.e., after
the First operation is closed in year 15).
These commenters suggested that such
costs, when discounted to the present,
are significant (i.e., on the order of 25
percent of the total compliance costs).
EPA acknowledges this comment to
be true. A 15-year life without
replacement of equipment or facilities
was assumed for simplicity during the
analysis. Data provided by facility
operators in response to the 1989
SWMPF Survey and the Agency's
understanding of relevant mineral
commodity markets suggest that an
assumed 15-year operating life is not
unreasonable for some facilities. In
other cases, however, it is unclear
whether this is or is not a valid
assumption. In those cases, the
remaining life of the facilities cannot be
predicted with accuracy. EPA
acknowledges that in situations in
which the facilities would continue to
operate and would require new waste
management units periodically,
annualized compliance costs would
increase over those reported in the RTC,
even by 25 percent or more. In any
event such an increase does not effect
today's regulatory determination.
5. Accuracy of Cost Estimates. EPA
received several comments regarding
the accuracy of its cost estimates. While
many commenters argued that EPA
provided inaccurate cost estimates for
regulating the 20 special wastes, one
commenter contends that, although EPA
ignores many of the costliest elements of
the subtitle C program, the Agency's
economic analysis accurately
demonstrates the high cost impacts of
regulating Bevill wastes under subtitle
C.
In its analysis, EPA employed an
engineering design model and detailed
cost analyses to develop realistic cost
estimates of subtitle C regulation. After
review of the comments and upon
further analysis, EPA continues to stand
by its cost estimates (as modified) as
adequate and appropriate for their
intended use as input to the regulatory
determination, even though some cost
considerations were excluded from the
analysis for most wastes (e.g., corrective
action). Furthermore, EPA notes that
high costs alone are not determinative of
appropriate regulatory status. Rather.
the financial impact of such costs is the
real measure of economic feasibility.
Section F below provides additional
comments on economic impacts.
6. Maximum Flexibility.
One commenter asserted that EPA
should calculate subtitle C-Minus
compliance costs on the basis of a
realistic level of flexibility under RCRA
section 3004(x) rather than on the
maximum level of flexibility. Unless the
maximum flexibility rules can be
guaranteed, contends this commenter,
firms may be faced with the unpalatable
choice of investing in "maximum
flexibility" waste disposal facilities in
year one. only to find that they need
"full subtitle C" facilities in year three.
As was clearly stated in the RTC. the
purpose of EPA's evaluation of three
regulatory scenarios was to demonstrate
the range of potential compliance costs.
not to articulate a new regulatory
program (which was beyond the scope
of the RTC). The Agency believes that
using a hypothetical subtitle C-Minus
scenario is appropriate for considering
the feasibility of subtitle C regulation of
special mineral processing wastes.
because of the significant technical
challenges that stringent regulation of
special wastes (by definition) may pose.
Moreover, the Agency believes that the
"realistic" level of flexibility that may in
fact be appropriate needs to be
determined based on a detailed
evaluation of site-specific conditions,
which was not possible within the
context of the RTC because of data
limitations.
7. Relative Costa of subtitle C, C-
Minus, and subtitle D-Plus. Several
comments were submitted to EPA
regarding the relative costs of the
subtitle C, C-Minus. and subtitle 0-Plus
regulatory scenarios. Many of those who
commented, recognizing the different
cost implications of each scenario,
encouraged a subtitle D determination.
while others argued that because the
differences in estimated costs among the
scenarios for certain wastes are
insignificant, a subtitle C determination
should be promulgated. One commenter
argues that with little cost difference, a
subtitle C determination would offer
greater environmental protection
advantages. Another commenter stated
that the differences between subtitle C-
Minus and subtitle D-Plus regulation are
likely to be especially apparent with
respect to corrective action costs (which
EPA did not include) because inclusion
of the processing wastes under subtitle
C-Minus may expose the facilities to the
same corrective action requirements
(and costs) as those under full subtitle
C. This same commenter added that
non-hazardous wastes should not be
regulated under subtitle C (through
application of corrective action) simply
because such regulation is projected by
EPA to be only slightly more costly than
subtitle D regulations.
EPA responds that the cost of
alternative management practices is but
one of the study factors that EPA is
required to consider therefore, the
regulatory determination is not being
made on the basis of the comparative
cost difference between subtitle C and D
programs alone. The Agency does
recognize that similar corrective action
requirements might be applied under
both subtitle C and C-Minus, and has
examined the associated costs (as
discussed above).
In addition. EPA notes that the
regulatory scenarios that were used to
estimate potential compliance costs
were developed with consideration of
the environmental protection that they
would afford. Thus, it is not the case
that subtitle C regulation necessarily
would provide more environmental
protection that the other scenarios
considered. For example, in some cases.
adequately protective design and
operating standards for new waste
management units under subtitle C-
Minus and D-Plus have been defined by
EPA to be identical.
F. Estimation of Economic Impacts
1. Inaccurate Use of Price Data. One
commenter identified a specific concern
-------
27324 Federal teggtet / VoL 5ft No; 114 / Thnraday. June 13. 1991 f RViIes aad HfegBJatJons
with EPA's use of estimated mineral
•prices in 1995, with no explanation a* to
how they were derived other than thai
they were reported by an EPA
subcontractor. This commenter claimed
that EPA did not verify its data by
contracting industry sources.
Contrary to the commenter's claim.
the Agency used industry experts
retained for this purpose to estimate
projected 1995 prices. Industry and
affected facility input and review prior
to the publishing of the RTC were not
possible because of procedural
constraints. Affected parties were.
however, encouraged to review the RTC
estimates during the public comment
period. In response to comments
received. EPA has in fact made
corrections to the prices reported in the
RTC for refined lead and merchant
grade phosphoric acid, which had
resulted from calculation and
transcription errors; estimated impacts
on the corresponding facilities and
sectors have been revised in support of
today's regulatory determination. As no
alternative long-term price projections
were suggested by commenters for the
remaining primary mineral commodities.
estimated long-term real prices remain
as reported in the RTC.
Furthermore, the Agency notes two
points that reduce the importance of the
use or accuracy of the 19U5 projected
prices. First, while the prices are.
important in assessing the overall
magnitude of the economic impacts.
their accuracy will not greatly affect the
difference between or relative impacts
of subtitle C versus D regulation; that is,
the magnitude of the impacts will be
effected to a far greater extent than the
relative differences between scenarios.
Second, if the prices as used are
potentially underestimated (in many
cases, estimated 1995 prices are lower
than current prices), the impacts in the
RTC are overestimated because the
estimated value of shipments (price
multiplied by production quantity)
would be smaller and the coat as a
percentage of value of shipments,
therefore, larger. This is the case for the
majority of the sectors, and is consistent
with EPA's objective of performing a
conservative and defensible analysis.
Only in the titanium tetrachloride sector
were prices projected to increase
significantly, raising the possibility thai
EPA's estimated value of shipments was
overstated and the impacts on that
sector were, therefore, underestimated.
However, given the strength of that
sector (as evidenced by the planned
construction of several new domestic
plants). EPA believes that the long-tern
projection of prices for that sector are
reasonable and that impacts are not
significantly understated.
2. Impact on Industry. Several
commenters argued that industries
producing primary copper, lead, zinc
and elemental phosphorus would be
adversely affected by a subtitle C
regulatory determination because the
regulations would generate additional
and substantial annual fixed costs that
would have to be met regardless of
market conditions. Several of these
commenters argued that these costs are
likely to remain fixed even in periods of
slack demand, contributing to depressed
profits during such periods. A few of
these comraenters further argued that a
decreased profit margin would make the
market less desirable to investors.
thereby discouraging the overall
economic growth of the industry.
EPA recognizes that increased costs
that cannot be passed along reduce
profits at all times, irrespective of
market conditions. The costs of
adequate environmental protection are.
however, simply a component of the
total cost of doing business. In trying to
evaluate future trends and market
conditions, the Agency did conduct
qualitative analyses of sectors for which
it believed the industry was subject to
potentially significant compliance costs.
and included the results of these
analyses in the RTC. For example, die
impacts discussions for the copper.
ferrous metal, lead, phosphoric acid,
titanium tetrachloride, and zinc sectors
included examinations of both the
present and future general competitive
position of domestic producers, and the
potential for compliance cost pass-
through (discussed more fully below).
EPA believes that its discussion of
future trends and market conditions has
adequately addressed the concerns
regarding long-term impacts.
3. Pass-Through Potential Several
coaunenters indicated that EPA should
not assume that the mineral processing
industry can pass on the costs of new
regulatory requirements to the product
consumer in the form of higher prices. A
few of these commenters noted that the
world market sets the commodity prices;
if American producers raise their prices.
consumers will look to international
markets, where products could be
obtained at lower prices. These
commenters agreed that higher pricing
on mineral processing products could be
devastating to the industry.
EPA understands that higher prices in
any market can cause adverse impacts
on the affected industry. EPA believes.
however, that the commenters'
suggestions that all mineral processors
in all commodity sectors are "price
takers" having no ability to pass on cost
increases and tlieiefuie having to
absorb tnem internally, is demonstrabM
untrue. fl
In general, the pass-through of
compliance costs follows me path of
least market resistance. Where all
facilities in the affected sector face
similar compliance costs and produce
commodities for which there are few
alternative supply sources or substitute

may be true. Similar possibilities exist in

costs depends on the initial incidence of
compliance costs within the affected
sector and the concentration and

compliance costs can be passed

//. Decision making Methodology for the
Regulatory Determination
One conmenter argued that EPA's
second approach, which recommends
that the Agency not regulate any of the
wastes studied in the RTC as hazardous
because of the potential for improved
state mineral processing programs, is
not authorized by the statute, is
factually insupportable, and unlawful.
adding that the authority for EPA's
second approach does not arise from the
study factors in section 8002(p) of RCRA
and that EPA's regulatory determination
must be directed by the specific
provisions of the Bevill Amendment
This commenier further argued that
states cannot regulate mineral
processing wastes adequately without a
national hazardous waste designation,
stating that there are no federal
programs for noaaaxardous waste in
place and ao statutory authority '
ensure that state noohazardous '
programs adequately regulate mini

processing wastes. This same
conunenter stated (hat EPA's assertions
in the RTC about the success of
individual state mineral processing
waste management control efforts are
uncertain and impossible to assess at
the present, and therefore cannot
support the use of EPA's second
approach. In addition, this commenter
stated that by delaying regulatory action
with EPA's second approach. EPA
would substantially undermine the two
principal objectives of RCRA: Overall
protection of human health and the
environment and the minimization of
generation and land disposal of
hazardous waste. Finally, the
commenter argued that if the Agency
decides to consider factors beyond the
eight listed in section 8002(p), then it
must consider all objectives and goals of
the RCRA statute, not just a select few.
On the other hand, several
connnenters encouraged EPA to apply
Approach 2 to its regulatory
determination, stating that the
development and maintenance of strong
state programs and federal regulations
under other statutory authorities is. in
fact, mandated by RCRA. These
commenters further argued that the
flexibility offered by Approach 2 for
regulation of the mineral processing
industry is essential to its continued
strength and growth, which the BeviB
Amendment was enacted to ensure.
Other commenters argued that the
"other factors" discussed for Approach
2 were, in fact embodied in the study
factors and should be considered in
Approach 1.
As was stated in section II of this
preamble, EPA generally agrees that it*
regulatory determination should be
baaed on me eight study factors outlined
in section 8M2(p) of RCRA, as embodied
in the Report to Congress, a* well as the
public comments and additional
information received in response to the
Report (and developed by EPA to
supplement the Report in response to
comments). EPA also agrees that, to the
extent that the Agency were otherwise
to conclude that subtitle C regulation
was warranted based upon
consideration of ail of these factors and
information, that it would be improper
to look outside the Report to Congress.
public comments, and supplemental
technical information to justify a
different determination. Therefore. EPA
has decided not to employ Approach 2
as outlined in the Report to Congress in
making today's regulatory
determination, and has instead
employed an Approach 1 methodology
(modified slightly, as discussed in the
main text).
EPA aise agrees somewhat with
commenfers who asserted that the so-
called "additional factors" open which
Approach 2 was baaed are, in large part.
already embodied witfem the contours of
the inquiry that Congress intended for
EPA to make in the Report and
regulatory determination. The Report
identifies (1) the development and
maintenance of strong state mining and
mineral processing regulatory programs,
and (2) the facilitation of an integrated
federal mining regulatory program as the
key considerations under Approach 2.
Section 8002(p){5) instructs EPA to
consider "alternatives to current
disposal methods" as a factor in
developing the Report and regulatory
determination. Certainty, consideration
of alternative state regulatory schemes.
in addition to federal schemes, is
contemplated by this section, in
addition, facilitation of a potential
integrated federal mining program was
actually considered by EPA in its cost
estimates (reflected in the "subtitle D-
Plus scenario").
Nonetheless, EPA does not believe
that it should rely on possible improved
state programs to determine that subtitle
C is not warranted unless EPA w
confident that such programs axe being
developed and can address the
problems associated with mineral
processing wastes that may pose a
significant risk. Thus EPA disagrees that
section 8002(p) requires EPA to consider
these factors in any way that would
supplant a decision the Agency makes
under the decision making methodology
outlined in Approach 1.
In any event. EPA notes that the issue
is effectively moot. As discussed in the
section III of this preamble, EPA has
been able to make its regulatory
determination for all 20 wastes OB the
basis of a slightly modified Approach 1
alone. Subtitle C was found not to be
warranted for any of the wastes
analyzed. Thus, even if EPA were to
employ Approach 2 as originally
conceived in the Report, it would not
change any of the decisions made today.
lit Wastes for Which Regulation Under
RCRA Subtitle D is Generally Supported
Nine of the twenty special mineral
processing wastes studied in the Report
to Congress were found to pose few if
any risks to public heahh or the
environment. EPA tentatively
recommended a subtitle D regulatory
determination for these wastes in its-
Report and continue* to believe that
subtitle C regulation is unwarranted.
The Agency received no comments en
the Report suggesting a contrary
position. The nine wastes include: (1)
Red and brown muds from bauxite
refining: (2) gasifter ash from coal
gasification; (3} process wastewater
from coal gasification: (4) slag tailings
from priaaary copper processing: (5)
fluorogypsum from hydrofluoric acid
production; (6) treated residue from
roasting/leaching of ckrome ore; (7)
process wastewater from primary
magnesium processing by the anhydrous
process: (8) basic oxygen furnace and
open hearth furnace slag from carbon
steel production; and (9) iron blast
furnace slag. Therefore, the Agency is
today finalizing its decision, as proposed
in the RTC, for these nine wastes.
IV. Wastes for Which the Regulatory
Determination is Contested
EPA received numerous comments
regarding the Report's recommended
regulatory determination for 11 wastes:
(1) Slag from primary copper processing:
(2) slag from elemental phosphorus
production; (3) air pollution control
dust/sludge from iron blast furnaces: (4)
air pollution control dust/sludge from
basic oxygen furnaces and open hearth
furnaces from carbon steel production:
(5) phosphogypsum from phosphoric
acid production: (6) process wastewater
from phosphoric acid production; (7)
slag from primary zinc production: (8)
calcium sulfate wastewater treatment
plant sludge from primary copper
processing; (9) process wastewater from
hydrofluoric acid production; (10) slag
from primary lead production: and (11)
chloride process waste solids from
titanium tetiacbloride production. As
discussed in section 1.C.3 of this
preamble, the Report tentatively
recommended, based on decision
making Approach 1, that the first seven
of these wastes be regulated under
subtitle D, white the last four be
regulated under either subtitle C or D.
depending on the scenario modeled.
The comments focused on the Report's
analysis of the section 8002(p) study
factors for each of these wastes, as well
as the Report's tentative conclusions.
EPA received at least one comment
arguing that subtitle C regulation of each
of the 11 wastes is warranted The

Alternative Management Practices for
Phosphogypsum and Process
Wastewater From Phosphoric Acid
Production
A. Subtitle C-Minus and D-Plus
Scenarios as the Basis for the
Regulatory Determination
Twenty commenters questioned the
appropriateness of using the Subtitle C-
Minus and D-Plus scenarios as a basis
for the regulatory determination.
Specifically, the commenters contend
that because these two scenarios are
hypothetical and because regulatory
requirements for the scenarios have not
been established, the two scenarios
cannot be used as a basis for a
regulatory determination, and costs
estimated for these two scenarios
cannot be used to make a decision as to
whether or not regulation under the
existing subtitle C program is
warranted. Furthermore, the
commenters believed that the Agency
assumption (and cost estimates resulting
from that assumption) that certain sub-
scenarios for management of process
wastewater and/or phosphogypsum
would be identical under a C-Minus
scenario and a D-Plus scenario is
illogical. The commenters concluded
that EPA must make its decision
between the subtitle C and subtitle D
programs and not on variations (i.e.. C-
Minus and D-Plus) of the two programs.
EPA disagrees with these comments.
Section 3004(x) of RCRA allows the
Administrator to modify certain subtitle
C requirements, at his discretion, so as
to "take into account the special
characteristics" of the wastes in
question. Such modifications are
"hypothetical" and have not been
"established" to the extent that to date.
none of the special wastes to which
section 3004(x) applies have been
regulated under RCRA subtitle C. As
discussed at length in the RTC. the
Subtitle C-Minus scenarios articulated
in the RTC and in the Supplemental
Analysis represent realistic (though
maximal) application of the regulatory
flexibility provided by the statute. The
Agency has provided cost estimates for
implementation of section 3004(x)
flexibility because it believes that a
tailored subtitle C program is less costly
and may be less burdensome to industry
so as to address the risks posed by
phosphoric acid industry special wastes.
The Agency recognizes that the contours
of a prospective subtitle D program for
mineral processing wastes have yet to
be established. Nonetheless. EPA
believes that for analytical purposes, it
was appropriate to consider one
possible approach to such a program, to
estimate the costs and impacts that
would result from implementation
thereof, and to compare these estimates
to those of the other regulatory
scenarios, in order to develop an
understanding of the potential
differences between environmentally
protective approaches to special wastes
management under the provisions of the
two potentially applicable portions of
the RCRA statute. Finally, the fact that,
in the Agency's view, adequately
protective tailored approaches to waste
management under subtitle C and
subtitle D are very similar in terms of
requirements and their costs does not in
any way invalidate EPA's analysis.
Rather, this suggests only that: (1)
Current management controls are
inadequate in some cases (as discussed
at length in the RTC and elsewhere in
today's notice, (2) that even under a
Subtitle D program, certain site
conditions and waste management
practices (such as are found at many
phosphoric acid plants) would require
fairly stringent controls and changes in
current practice to adequately protect
the environment, and (3) that the
flexibility afforded by section 3004(x)
can be employed to develop
management standards that are
achievable while also ensuring
protection of human health and the
environment.
B. Technical Feasibility of Engineering
Alternatives
The Agency received comments on
several aspects of the feasibility of the
engineering alternatives (discussed in
the NODA). Several of the comments
are summarized below; the remainder
are addressed in the supporting
comment response background
document.
1. Use of Undemonstrated
Technologies. Several commenters
objected to EPA's presentation of
engineering alternatives that incorporate
certain technologies that are considered
by the industry to be undemonstrated.
unproven. and/or experimental. The
commenters contend that waste
management scenarios that utilize
undemonstrated technologies cannot be
used as alternatives to current waste
management practices under the
definition of section 8002(p) of RCRA.
The commenters contend that each of
the "Subtitle C compliance scenarios"
(Engineering Alternatives 1. 2. and 7)
incorporate one or more technologies
that are not currently demonstrated in
ng:
iratic^l
STW
the industry as feasible. These
technologies include the following:
• Segregation (hydraulic separatif
of waste management units for pr
wastewater and phosphogypsum
(Alternatives 1,2. and 7);
• Neutralization of phosphogypsum
slurry, disposal of limed gypsum on
existing stacks, and return of transport
water to the production process
(Alternatives 1, 2, and 7);
• Recovery of fluosilicic acid from the
reaction stage of phosphoric acid
production (Alternatives 2 and 7); and
• Use of cooling towers and indirect
cooling via heat exchangers to effect a
closed-loop cooling system in lieu of a
process wastewater cooling pond.
As an example of undemonstrated
technology, the commenters stated that
even though lime neutralization of
process wastewater is used at some
plants before NPDES-permitted
discharge, neutralization of all process
wastewater and subsequent recycle to
the production process has not been
successfully demonstrated at an existing
plant. Because this technology and the
other technologies are undemonstrated
in the industry in the manner in which
they are intended to be used in the
engineering alternatives, the
commenters argued that the subtitle C
engineering alternatives cannot be used
as a basis for a regulatory deter
to regulate the industry under:
EPA largely disagrees with
comments. The commenters' proposed
definition of "demonstrated" is extreme
and contrary to long-standing Agency
policy. While EPA agrees that there
must be an expectation that a given
technology will perform adequately if it
is to serve as the basis for a regulatory
decision, the Agency does not agree that
current use of the technology in the
industry being examined is necessary. In
fact, it is very often the case that
technologies and techniques that have
been developed elsewhere for different
purposes are used by the Agency for
achievement of new pollution control
standards. This type of "technology
transfer" is at the very heart of such
programs as Clean Water Act Effluent
Guidelines development and
establishment of Best Demonstrated
Available Technology (BOAT)
requirements under the RCRA Subtitle C
Land Disposal Restrictions.

technologies that comprise engineering

technologies have been demonstrated in

use ia the phosphoric acid industry ia
mam reflective oi an absence of strong
regulatory central* and associated
financial incentives than of the
feasibility or availability of the
technologies themselves. Specifically.
EPA has at least anecdotal evidence
that closed loop cooling and recovery of
FSA from the reactor/flash cooler
system have been successfully
employed in other industries and in
foreign phosphoric acid plants,
respectively.
Moreover, EPA wishes to make clear
that it believes that the commenters
have misinterpreted the Agency's
response to the statutory requirement to
examine "alternatives to current
disposal methods" and "the coals of
such alternatives" (RCRA section
8002(p), study factors 5 and 6). As
pointed out by the commenters, in the
RTC, EPA discussed a number of
alternatives to current waste
management practices, focusing on
techniques that have been applied on a
commercial scale to reduce the quantity
and/or toxicity of the special wastes-
considered in the Report The intent of
tins discussion was to achieve partial
fulfillment of study factors 5 and 8
(potential utilization) by focusing on
proven means of source redaction and
waste minimization as an alternative to
on-site waste management. For most of
the 20 special wastes considered m the
RTC, opportunities for recycling and
commercial ose are quite limited, for
various reasons. In contrast. EPA's
approach to responding to the remainder
of study factor S as welt as study factor
6 was to articulate and estimate the
costs of on-site waste management
under alternative regulatory scenarios.
The Agency believes that this context
was and is the most relevant to the key
decisions to be made (Subtitle C vs.
Subtitle D regulation) based upon the
findings of the RTC and subsequent
analysis. Thus, there is no direct linkage
between EPA's criterion for discusaioa
of a waste management alternative or
opportunity for utilization and the
development and analytical
implementation of the regulatory
scenarios presented in the RTC and the
Supplemental Analysis. Accordingly,
EPA categorically rejects the
comroenters' assertion that a given
technology, device, and/or practice must
currently be in use within the domestic
phosphoric acid industry in order for it
to be considered "technically feasible.''
The Agency further rejects the
commenters' suggestion that EPA's own
methodology as articulated ia the RTC
compels such an approach. becMS*
commenters have misconstrued the
Agency's analytical methods and
undettyiag rationale.
The Agency acknowledges that there
are significant uncertainties regarding
the operational consequences of the
lime treatment of phosphogypcum. Once
again, however, commenten have based
their arguments upon an inaccurate
interpretation of EPA's analysis. The
treatment of phosphogypsuro
contemplated in engineering alternatives
1, 2, and 7 assumes that the water being
used to slurry the gypsum from the filter
to the neutralization mixing basin would
be treated process wastewater. not the
"pond water" that is currently managed
at active facilities.
Consequently, the laboratory test
results reported by the commenters in
support of their argument are. in the
Agency's view, of questionable
relevance, and by no means
demonstrate that treated gypsom would
present significant disposal and other
operational problems.
Finally, EPA believes that the
importance of the issue of segregation of
the gypsum management and cooling
water areas within a facility's waste
management system has been
overstated by the commenters. m (he
Supplemental Analysis, EPA disctwsed
a number of different approaches for
separately addressing coHtamrnanto
contained in phosphogypsum slurry amd
contaminants condensed into cooling
waters. In no case did EPA state (or
even suggest) that a complete hydraulic
separation between gypsum
management units and cooh'ng ponds
would be either necessary or
appropriate, even under a fuH subtitle C
scenario. Indeed the Supplemental
Analysis recognizes that leachate wiO
continue to be generated for many year*
from auy existing gypsum stack. To the
extent that this leachate or gypsum
transport water (which would have been
rendered non-hazardous under
engineering alternatives 1,2, and 7)
might enter the cooling water pond
treatment or product recovery would
occur through removal of this water to
the treatment system or filter,
respectively. In either case, "co-
mingling" of separate hazardous wastes
would not occur, obviating the need for
complete hydraulic separation and any
associated undesirable effects on plant
water balance.
2. Feasibility of Lime Neutralisation.
Several commenters expressed doubt
over the engineering feasibility of Mm*
neutralization of both process
wastewater and phosphogypsnm, for
several reasons, including the limited
availability of lime to meet the demand
that would be created and the formation
of a attka gel that wooU interfere with
warte management and prod actions
peaces* operations.
Several commenters argued that the
demand for lime imposed by any of the
engineering alternatives that incorporate
lime neutraftzatkm would piece a severe
burden on the United States Kme
production industry. The comnenters
stated that implementation of
Engineering Alternative 1 (lime
neutralization of all waste streams)
would require the southeastern Imte
industry to triple its present capacity m
the first year of implementation of the
alternative to meet the additional
demand, hi addition to expressing their
uncertainty over whether this demand
could be met. the commenters also
expressed concern over potential
environmental impacts that the demand
would create, including increased
generation of carbon dioxide, increased
fuel consumption, and the need for
additional limestone strip mines.
In response to this comment EPA has
conducted additional analysis to
determine whether implementation of
Alternative 1 would impart significant
impacts on lime supply, demand, and
capacity within the relevant regions of
the country. A description of this
analysis and the results thereof may be
found in the docket1 These results
suggest several conclusions.
First, EPA agrees that adoption of
engineering alternative 1 by the entire
domestic industry would significantly
increase the demand for lime in the
regions of the country in which the
active phosphoric acid plants are
located, requiring an increase in lime
production. In the western states (Idaho
and Wyoming), this increase could
probably be met through greater
utilization of existing lime production
capacity. In the south, uniform adaption
of engineering alternative 1 would
create demand in excess of regional
supply, requiring shipments from other
parts of the country (e-g., Ohio.
Pennsylvania), installation of additional
lime capacity, and/or imports of lime
(probably from Mexico).
Second, the analysis of incremental
lime demand presented by the
commenters significantly overstates the
impacts of new regulatory requirements,
for several reasons. The estimates of
lime demand presented by the
commentea are substantially higher
than EPA'a estimates. Because the

Ptuwphoric Add Production. Prepared For the Offic*
-------
27328 Federal Register / Vol 5ft No. 114 / Thursday. June 13> 1991 / Rules and Regulations
reasons for this difference have not been
adequately explained in the materials
submitted to the Agency, EPA continues
to believe that its lime consumption
estimates for engineering alternative 1
are valid. Moreover, in comparing
demand with supply, commenters were
quite selective in terms of which states
and lime plants were defined as being
located within the same region as the
phosphoric acid plants. EPA believes
that lime produced in Virginia,
Kentucky, Illinois, Indiana, Missouri,
and Texas is also available (in a
logistical and economic sense) to the
potentially affected phosphoric acid
facilities, particularly those located in
Louisiana. Texas, and North Carolina.
Therefore, the gap berwaen potential
demand and existing supply is
substantially narrower than that
suggested by the commenters.
Third, the Agency acknowledges that
implementation of any alternative that
substantially increased the demand for
lime would result in increased energy
consumption and releases of carbon
dioxide, a "greenhouse" gas. to the
atmosphere. Because many lime and
limestone producers are operating at
levels substantially below their
capacity, however. EPA is not convinced
that opening of additional limestone
mines would necessarily be required to
any significant degree as a result of
implementation of the engineering
alternatives, though additional
production from existing mines would
clearly be needed.
Finally, and most importantly, the
comments focus on a worst-case
scenario under which every plant would
lime treat all of its special wastes.
Under a tailored subtitle C (C-Minus)
program, this is but one option among
many. EPA believes that most facility
operators, when provided with the
incentive to comply in a least-cost
manner, would develop alternatives to
lime treating all of their wastes, thus
greatly reducing the amount of lime
required and the importance of this
issue.
Commenters also stated that a
colloidal silica gel would be created
during the neutralization of process
wastewater and phosphogypsum. The
commenters argued that this gel is likely
to remain in suspension in both the
gypsum transport water and the cooling
pond process wastewater. which may
pose significant problems in the
operation of plant equipment when
these waters are returned to the
production process. In particular.
several commenters stated that the gel
would potentially "blind" (clog) the
phosphogypsum filter when the treated
gypsum transport water is returned to
the filter and reused as filter washwater,
resulting in decreased efficiency,
increased downtime, and lost
production. Commenters also indicated
that they were unaware of any
demonstrated technology to remove the
gel from the phosphogypsum filters.
EPA is not convinced that the
catastrophic operational effects
predicted by the commenters would
occur on a widespread and continuing
basis if lime treatment of the special
wastes were to be instituted,
particularly if FSA recovery were to be
practiced. Commenters have assumed
that the engineering alternatives
contemplated by EPA would involve
continual treatment of process
wastewater and phosphogypsum as they
are currently generated, when in fact the
alternatives were developed to address
management of new waste streams
having different chemical characteristics
resulting from treatment and/or product
recovery. Therefore, the appropriate
question is whether lime treatment of
process wastewater that has not
reached a high equilibrium
concentration of chemical contaminants
would result in significant gel formation.
not whether lime treatment of currently
generated "pond water" would create
such operational problems.
Nevertheless, EPA does have some
concerns about the efficacy of • lime
treatment strategy. For example, the
Agency recognizes that for a period of
time (perhaps one to two yean).
treatment of existing pond water would
occur. To the extent that gel formation
took place, operational difficulties might
be significant. Because, however.
implementation of today's decision does
not require that lime treatment be
implemented. EPA does not believe that
resolution of this issue (which would
require additional research) is necessary
prior to a determination of the
appropriate regulatory status of the
special wastes from phosphoric acid
production.
3. Feasibility of Separate
Management of Phosphogypsum and
Process Wastewater. Commenters
expressed concern over the technical
difficulty inherent in separately
managing phosphogypsum and process
wastewater so that no hydraulic
communication between the two
"circuits" is permitted. Because the
integrated management of these two
wastes is employed at all existing
facilities and is. according to the
commenters, essential to maintaining •
negative water balance (i.e., zero
discharge through NPDES outfalls), the
commenters believed that the separate
management of these two wastes is an
undemonstrated technology that cannot
be used to support a regulatory
determination. One commenter
performed a computer modeling studyTo
predict his facility's water balance
under Engineering Alternatives 1 and 7
and predicted that separate
management of process wastewater and
phosphogypsum at the facility would
require treatment and discharge of
excess process wastewater.
Commenters indicated that the potential
increase in discharge created by
segregated management would be
contrary to the objectives of the Clean
Water Act effluent guidelines as well as
NPDES requirements for the industry.
Furthermore, the commenters pointed
out that the Agency addressed neither
the feasibility nor the cost of
implementing separate management of
the wastes.
As discussed above, the Agency has
never suggested that it would require
complete hydraulic separation of the
areas dedicated to gypsum disposal and
process water cooling. In addition, the
computer simulation results submitted
by the commenter assume no changes or
adjustments in the operation of the
plant an assumption that is contrary to
standard industry practice. Plants
continually monitor water balance^
modify their water management
activities as needed to comply wit
discharge limits and operational
requirements. EPA has received no
convincing evidence that suggests that a
new water balance could not be
developed for affected plants, though
admittedly, new equipment and piping
might be necessary in some situations.
Accordingly. EPA believes that the
potential impacts on plant water
balance and associated regulatory
significance of the issue as suggested by
the commenters are substantially
overstated.
4. Land Required To Implement
Subtitle C Compliance Alternatives.
Some commenters contend that
adequate amounts of land are
unavailable to implement the subtitle C
compliance alternatives (Alternatives 1.
2. and 7); hence, the commenters stated
that implementation of these
alternatives under subtitle C is
infeasible. The commenters contend that
the implementation of tiiese alternatives
would require the construction of new
waste management and treatment units
and expansion of existing waste
management units on land that is in
addition to acreage already occupied at
the facilities. Specifically, the
commenters stated that in order I
implement Alternative t (lime
.»
itM^
-------
Federal Register / Vol. 56, No. 114 / Thursday. June 13. 1991 / Rules and Regulations 27329
neutralization of all waste streams),
additional land would be required for
(1) Extra filter capacity; (2) lime
receiving and slaking facilities; (3) a 50-
acre gypsum transport water pond; (4)
an additional SO acres of cooling ponds;
(S) a cooling water neutralization basin;
(6) a larger stack: and (7) cooling water
sludge ponds. Many of the facilities that
commented claimed that they did not
have enough land available to
accommodate all of these units, and
many of these facilities reported that
they could not purchase adjacent
property of sufficient size.
EPA continues to believe that the
availability and cost of land needed for
regulatory compliance are not critical
issues. As discussed in more detail
below, the Agency believes that the
commenters' estimates of the size of
new required waste management units
are significantly overstated. Also.
additional land required for many of the
items listed by the commenters (e.g..
extra filter capacity, lime receiving and
slaking facilities, neutralization basin) is
quite modest in extent, particularly
within the context of the vast scale of a
domestic phosphoric acid plant (all of
which are hundreds or thousands of
acres in size). Moreover, to the extent
that substantial new acreage is required
for additional waste management units,
land could be acquired that was not
adjacent to the facility, i.e.. the units
could be sited at some distance from the
plant. EPA believes that the incremental
costs of managing the phosphoric acid
wastes in this manner would be modest
because the wastes are already piped
(in slurry and liquid form) considerable
distances (hundreds of yards) at some
plants. Therefore, the Agency believes
that "extending the pipeline." even for
several miles, is not a significant issue,
from either a feasibility or cost
standpoint.
C. Costs of Engineering Alternatives
The Agency received comments on
several aspects of the estimated costs of
the engineering alternatives. Several of
these comments are summarized below;
the remainder are addressed in the
supporting comment response
background document
;. Operating Year. Commenters
argued that EPA significantly
understated the costs of the engineering
alternatives by basing its calculation of
annual incremental compliance costs
per ton of P»O» output on a 365-day
production year. The commenters
contend that it is not possible for
phosphoric acid facilities to operate 365
days in a year and that due to
necessary maintenance, facilities
operate, on average.'330 days per year.
Data submitted by individual facility
operators in EPA's 1989 National Survey
of Special Wastes from Mineral
Processing Facilities demonstrate that
most phosphoric acid plants operated
for more than 350 days in 1988.
Nonetheless, EPA recognizes that
individual production lines within a
given plant are subject to considerable
down time for maintenance and repairs.
Because the model plant used to
evaluate the engineering alternatives in
the Supplemental Analysis was based
on a single production line, the Agency
has revised its cost estimates to reflect
the commenter's suggestion that a 330
day operating year be employed.
2. Capital Cost for Neutralization
Sludge Ponds. Commenters argued that
EPA seriously understated the capital
cost of installing sludge disposal
impoundments necessary to manage the
calcium fluoride sludge that would be
generated by lime neutralization of the
cooling water component of process
wastewater. The reasons given by the
commenters are:
(1) EPA's capital cost was sufficient
for only one year of sludge storage;
(2) The capital cost does not include
the cost of acreage needed to provide
adequate residence time for settling of
solids in the treated cooling water and
(3) Lining of the impoundment was not
included and would be required.
EPA generally disagrees with this
comment. The Agency recognizes that it
did not provide complete information
concerning engineering design
assumptions in the Supplemental
Analysis; this omission occurred
because of extreme time constraints.
EPA believes that many of the
commenters' concerns arise from
incorrect (though, in many cases,
reasonable) inferences that they have.
made based upon the limited
information that was available to them.
First, the sludge settling/disposal
impoundments referred to by the
commenter were indeed designed to
accommodate a 15 year accumulation of
process wastewater treatment sludge.
For engineering alternative 1, the
impoundment was designed to contain
118.271,000 cubic feet of sludge
(generation rate of 7.8 million cubic feet
or 180 acre-feet per year). Using the
same cost engineering model as
employed for the RTC, EPA estimated
that this impoundment would cover 64
acres (80 acres total, allowing for site
preparation activities), and have a depth
of 42 feet (14 foot dug out depth, 28 foot
berm height).
Furthermore, as clearly stated in the
Supplemental Analysis, the Agency
believes that the volume-of the sludge
disposal impoundment (the vast
majority of which would be available in
the early yean of operation) coupled
with the large volume of the existing
cooling pond, would provide adequate
residence time for solids removal
(settling) from the treated process
wastewater stream. Commenters have
provided no evidence or a rationale
supporting their contention that EPA's
assumptions in this regard might be
invalid: EPA concludes, therefore, that
its approach as described in the
Supplemental Analysis was and is
reasonable. Therefore, the Agency
believes that the commenters'
suggestion that the actual area required
for treated process wastewater and
sludge management (1.272 acres versus
EPA's estimate of 80 acres) is
significantly in error.
Finally, EPA does acknowledge that
there is a distinct possibility that the
sludge settling impoundments required
under Alternative 1 would require
composite liners, at least for facilities
located in the State of Florida. Florida
ground-water protection standards
(which incorporate federal MCLs) allow
individual permit writers, at their
discretion, to require the installation of
liners under new units to ensure
adequate protection of the ground-water
resource. Because the concentrations of
lime-treated process wastewater
contaminants such as sulfate and
sodium are likely to be an order of
magnitude or more above MCLs (they
are not removed to any significant
extent by lime treatment 2), EPA has
concluded that liners would probably be
required as a permit condition for any
CaFi sludge disposal impoundment(s)
that would be built in Florida as part of
a regulatory compliance strategy.
Therefore, to the extent that such
impoundments would actually be
constructed in response to new
regulations, EPA has underestimated the
associated compliance costs in the
Supplemental Analysis.
3. Cost of Separate Management of
Phosphogypsum and Process
Wastewater. The industry commenters
stated that EPA failed to consider the
capital costs and operating and
maintenance costs involved with
separately managing the cooling water
and phosphogypsum slurry circuits. The
commenters further contend that
separate management of these waste
streams would necessitate a major
retrofit of current waste management
units at existing production facilities.

-------
2733E Federal RegUrtar / Vol. 56. No. 114 / Thmaday, June 13. 199t / Rnles and Htyriatfema
The comraenten estimated that the cost
necessary to separate the gypsum and
cooling water circuits (capital cost) at
EPA's model plant would be at least $10
million.
As discussed above, the Agency has
never stated that it would require
complete hydraulic separation of the
areas dedicated to gypsum disposal and
process water cooling. Accordingly, EPA
does not believe that a plant retrofit to
achieve separation of these areas would
be necessary or required.
D. Economic Impacts of Alternative
Waste Management Practices
In general, all of the industry
commenters considered implementation
of the various alternatives under subtitle
C to be economically intractable. Based
on their analysis of the economic
impacts they believe would be imposed
by the implementation of engineering
alternative 1, the commenters concluded
that: (1) Implementation of the
alternative would eliminate the
industry's export markets: (2) it is
possible that foreign producers could
penetrate the domestic market: and (3)
incremental compliance costs could not
be reasonably passed on to suppliers,
workers, or consumers. The commenters
believed that these conclusions would
apply equally to impacts posed by
engineering alternatives 2 and 7.
EPA recognizes that implementation
of engineering alternatives 1, 2. and 7
under a subtitle C framework would
impose cost impacts that might be
difficult for members of the domestic
industry to withstand. The reel issue,
however, is the magnitude and
distribution of the impacts that might be
imposed by tailored subtitle C
standards. Under the Subtitle C-Minus
scenario presented in both the RTC and
the Supplemental Analysis, facilities
could achieve compliance by adopting
strategies to either contain or reduce/
eliminate contaminants in their special
wastes. Presumably, they would do so in
a manner that minimized costs, given
their own operational strategies and
site-specific conditions. Therefore, the
cost estimates provided in the
Supplemental Analysis should be
viewed as upper-bound estimates; it ia
likely that actual costs and associated
impacts would be lower (at least on a
per ton ftOk basis) than those estimated
for the model plant* This fact co
with diminished relevance of the cos
impacts of full suUtffle C regulation.
suggests that many of the claims made
by commenters are overstated.
//. Other Wastes Addressed in the
Notice of Data Availability
EPA received no comments on the
additional information regarding gasifier
ash and process wastewater from coal
gasification. However, the Agency did
receive two comments addressing the
supplemental analysis of basic oxygen
furnace dust/sludge from carbon steel
production. The Agency has taken the
comments into account in developing
this final regulatory determination.
EPA's detailed responses to the
comments are available for inspection in

Notes: 1) This Revision Checklist addresses an administrative stay of three wood preserving
waste listings (F032, F034, and F035) made at 55 FR 50450 (December 6, 1990; Revision
Checklist 82). Certain drip pad management standards, the inclusion of past users of
chlorophenolic formulation in the listing description for certain F032 wastes, and the scope of
waste water with respect to wastes that do not come into contact with preservative are also being
stayed. EPA considers that both the F032 listing and the new Subpart W drip pad standards
(when applied to the management of F032 wastes) are based on HSWA authority. This
administrative stay defers EPA's implementation and enforcement of the HSWA-based
requirements. On the other hand, the listings of F034 and F035, and the Subpart W drip pad
standards that govern the management of these wastes, are considered to be based on pre-
HSWA authority. For unauthorized States, the effect of this stay will also be to defer the EPA's
implementation and enforcement of the F034 and F035 provisions. In authorized States, however,
the non-HSWA requirements will not be applicable until the State modifies its program and obtains
approval for the revisions from EPA. The F032 stay is an extension of a HSWA compliance date;
States cannot adopt extensions beyond the Federal HSWA compliance dates. For the F034 and
F035 listings, however, States could adopt reasonable compliance date extensions (e.g., stay
schedules) that extend beyond the Federal stay dates announced in this rule.
2) States may elect to adopt wood preserving waste regulations with more stringent effective
dates than those announced in this administrative stay. For this reason, Revision Checklist 91

SUMMARY: The Environmental Protection
Agency is today announcing an
administrative stay of the hazardous
waste listings F032. F034. and F035 in
process areas at wood preserving plants.
The primary effect of the stay is to
conditionally extend the effective date
of the drip pad management standards
to February 6,1992. for the upgrade of
existing drip pads and to May 6,1992.
for the installation of new drip pads.
Certain management standards for drip
pads, the inclusion of past users of
chlorophenolic formulations in the
listing description for certain F032
wastes, and the scope of wastewaters
with respect to waters that do not come
into contact with preservative are also
being stayed.
DAT!*: Effective Date: June 5.1991. For
reporting deadlines, see section VI of
this preamble.

I. Background
On December 6,1990. EPA
promulgated regulations listing as
hazardous various wastes generated
from wood preserving processes that
use chlorophenolic, creosote, and/or
inorganic (arsenical and chromium)
preservatives (55 FR 50450 (Dec ft. 1990),
adding hazardous wastes F032, F034,
and F035 to the lists of hazardous
wastes in 40 CFR 281.31). In addition,
and of particular relevance for the
present notice, the Agency promulgated
standards for a new type of waste
management unit, a drip pad (55 FR
50484-89, adding a new subpart W to
parts 264 and 265 of the regulations).
Drip pads receive drippage from treated
wood immediately after the wood is
removed from the treatment vessel Tfce
pads are eligible for 90-day generator
accumulation status under | 262.34
provided they are designed and
operated in compliance with the subpart
W standards (amended { 262.34(a)(2),»
FR 50463-84). The standards vary
somewhat for new and existing drip
pads;
Because the rule was promulgated
partially pursuant to the 1984
amendments and partially pursuant to
preexisting authorities, the requirements
take effect at different times in different
states. As a HSWA rule, the F032 listing,
of various residues from wood
preserving processes using, or that
previously used, chlorophenolic
formulations takes effect on June & 1991
in authorized and unauthorized States
(55 FR 59469-70 and RCRA section
3001(e)). Drip pads used in connection
with F032 wastes are likewise subject to-
the subpart W standards on June 6 fat all
States (Id at 50470). The F034 and P03S
listings and related management
standards do not take effect
immediately in authorized States sinca
they were not adopted pursuant to

this level «f control is either redundant
or unnecessary. ki addition. they
questioned the technical feasibi&ty of
findsjg an impermeable sealer for some
arsenical solutions.
IV. Pentachloropheool Cross-
Conlamination
A further issue that concerns the
wood preserving industry is the scope of
the F032 listing (for wastes tram
processes using pentachloropheooi as a
preservative). As promulgated, this
listing includes wastes generated by
creosote or CCA plants that previously
used chJorophenelic formulations.
Although the rules provide a procedure
whereby an individual facitity can
demonstrate that crou-ccntamioatioa is
no longer occurring (in which case the
wastes from the process would stiD be
hazardous but classified uader cither the
F034 or F03S waste codes), the industry
argues that these procedures are
potentially unnecessary and
impracticable. Furthermore, by including
potentially cross-contaminated wastes
within the scope of the F032 listing, more
facilities become subject to the June 6
deadline, since £heF032 listing takes
effect on that date in both authorized
and unauthorized States since it is a
HSWA rule. This increases the number
of wood presenting facilities potentially
unable to comply with the drip pad
standards on that date.
V. Sccoe«f the WastswatarUstfcgs
The wood preserving industry further
questioned the scope of the listing of
wood preserving wastewaters. Among
other points, they contend that certain
wastewaters are not hazardous because
the wastewaters do not come in contact
WltTl "pPOCCSV
maintain farther that processes can be
reconfigured to avoid corrtamrnation of
other water, such as rainwater. Because
the listing applies to all wastewaters,
however, these efforti would be without
point because afl the wastewaters
wouio remain imukiddud fmress and
until deKsred).
VI. Agaocy Adtiaa
A. EPA has detnramiod to wsw «n
administrative stay ef the applicability
of the FMZ. W34 and FDA biting* to &•
process ana motiving dcippage of tmesa
wastes, i.e.. (bearta potentially «evered

As explained below, this) stay ti

facilities meting certain coadMom
:ntended to limit the extension t» *ws«
facnnfes making »ona nde £rTmt4 to
comply wnli the rule. For existing ttrip
pads, the stay wffl remain m effect until'
Febreery 8.19iL and for new drip pads,
the stay wfQ remain m effect until May
B. 198E.
The Agency hn selected these dates
for the following reasons. The Agency
believes that two month* of time beyond
the Jme 8.1991. effective date is
necessary for wood preserving plants to
determine and report their definite
intentions as to compliance with the
rule. The Agency believes that up to
three additional months will be required
for all facilities intending to come into
compliance to fully investigate and
obtain the necessary funding required to
retrofit existing pads and to construct
new pads. The retrofitting of existing
drip pads win1 require less time than the
construction of new drip pads. Thus, the
Agency has allowed op to three
additional months for the retrofitting of
existing drip pads and up to six
additional months for me cuitsUiilhm
of new drip pad*. These estimates are
consistent with information supplied by
the wood preserving industry. Based on
these estimates, the Agency feels Siat
final compliance dates of February o.
1992. and May «, 1991 are reasonable
compliance dates for plants with
existing drip pads and newly
constructed drip pads, respectively.
The effect of the administrative stay is
that activities (hat would otherwise
constitute disposal of F032, F03*. or F033
wastes into the process area, or onto
existing drip pads m process areas, are
not covered by the respective wood
preservative waste listings during dm
duration of the stay. The stay is limited
to the process area, huwevei. Titos, on
listings are not stayed for P032, P004. or
P83S wastes, inchrarng soil
contaminated with these wastes, that
are removed from this area. (During the
term of the edministi afire stay, such
removal would be considered geueiatluu
of «a PJ32, FOB*, or BBSS waste. 53 PR
31147-49 (Avgust 17.198fU
As noted eoove, the Agency Intends
(and AWCT expressly agrees) that mis
limited stay should apply orrry to those
facffittat (hat intend to comply with 4m
subpart W standards and (hat are
wfRing to nrnke bona fide efforts to do
so during the stay peiiud. It obviously
makes no sense to extend dm ram's
compliance date for facilities simply
desiring to continue operations tnar SJTV

operating wKhoot a drip pad or with
defective p*ds) until they are lorcai to
ens*. Consequently, the Agency is
making 4he •slay sjppBewWe orty to thow
facilities that comply wift the
conditions desurbed below. Faitnre to
comply with these conditions means
that the listings remain in effect in
which case process area drippage can
only occur lawfully for facilities with
compliant drip pads, or for facilities in
compliance with requirements lor land
disposal of hazardous waste (or other
units meeting applicable technical
standards). It should be noted that all
portions of the rule that are not stayed
remain in effect. For example, the stay
does not affect the March 6.1991. 3010
notification deadline for generators and
TSDs handling F034 and F005 in
unauthorized states or F032 in all states.
Thus, those generators and TSDs that
were managing the foreraeotioned
wastes, that had not previously notified
the Agency of hazardous waste activity.
and that did not submit a 3010
notification to the Agency by the
deadline ace ra violation of that
requirement.

27334 Federal Register / Vol. 56. No. 114 / Thursday. June 13, 1991 / Rule* and Regulations
Person* unable to make this
demonstration would have to cease
operation by November 7,1991. (The
scheme is somewhat similar to the
statutory loss of interim status
provisions which required certain
facilities to certify that the facility was
in compliance with financial
responsibility and groundwater
monitoring requirements by a particular
date or to cease operation (RCRA
section 3005(e)(2))). EPA repeats that the
rule remains in effect for persons who
do not comply with these conditions.
EPA or the state, as appropriate, may in
its discretion, allow a facility to operate
beyond the November 6,1991. deadline:
provided, that (1) The respondent
demonstrates that it cannot meet the
November 6,1991, deadline because of
circumstances entirely beyond its
control, despite its best efforts to comply
(e.g.. its impossibility of performance is
due to corrective action being
undertaken at the wood preserving
facility pursuant to a federal or state
order or permit), and (2) such
authorization to operate is set forth in
an enforceable compliance order.
B. EPA has also decided to issue a
stay of the requirement that new drip
pads be sealed, coated, or covered with
an impermeable material
(§ 264.572(a)(4). § 265.443(a)(4)). The
Agency is taking this step because we
are now convinced that this requirement
is unnecessary for pads constructed
with a liner and leak detection system
provided the pad if maintained in good
condition with actions taken to remedy
any cracks that may develop. The liner
would provide secondary containment,
thus fulfilling the Agency's object in
developing management standards for
drip pads (55 FR at 50453). We
consequently are staying this
requirement Thus, on May a. 1992 (i.e..
the date when new pads must comply
with the regulatory standards), new
pads will not be required to be sealed,
coated, or covered with an impermeable
material. EPA also intends to initiate
ruleraaking to determine whether to
make this a permanent regulatory
change.
EPA intends, however, that this
requirement remain in place for existing
pads, once those pads are required to
comply with the regulatory standard*,
because few (if any) existing pads are
known to have liner and leak detection
systems that comply with the subpart W
standards. Thus, on February 6.1992.
existing pads must be sealed, coated, or
covered with an impermeable surface.
Because existing pads need not have
liner and leak detection systems
(II 264.571.265.441) the requirement of
an impermeable surface is necessary to
provide secondary containment (The
Agency has determined that
commercially available sealants exist
that would be appropriate for use at the
pH of preservative solutions used by the
wood preserving industry.)
C. The Agency is also staying the
portion of the rule that included wastes
from plants generating F034 or F035
wastes that previously used
chlorophenolic formulations as within
the scope of the F032 listing. Upon
reflection, the Agency realizes that
structuring the rule in this way is not
serving any useful environmental
purpose. Wastes from creosote or
inorganic arsenical wood preserving
processes that previously used
chlorophenolics are already classified
as hazardous under the F034 or F035
listings. The regulatory standards for
F032. F034, and F035 wastes are
identical so that the F032 listing does
not carry with it a stricter regulatory
regime (55 FR at 50467). The only
immediate regulatory consequence of
the F032 listing for these plants is to
make more facilities subject to the June
6 compliance date. As explained above
in the discussion on compliance dates
for drip pads, this consequence has
negative features because many
facilities that can comply with the drip
pad standards with some additional
time appear unable to do so by June 6
for legitimate reasons. Since the F032
listing does not result in different
substantive regulation for the wastes
other than the timing of the effective
date, EPA has decided to stay the scope
of the F032 listing so that it does not
cover wastes from creosote or inorganic
arsenical plants that previously used
chlorophenolic preservatives as long as
any wastes from that plant are regulated
as F034 or F035 wastes. EPA also
intends to initiate rulemaking to
determine whether to permanently
amend the F032 listing.
The Agency notes, however, that the
issue of chlorophenolic cross-
contamination will be relevant when
EPA establishes treatment standards for
the F032, F034 and F035 wastes under
the land disposal restrictions program.
The fact that a waste may be classified
as F034/F035 rather than F032 does not
prevent the Agency from promulgating
treatment standards for the
chlorophenolic formulation, and the
various dioxins and furans that may be
present in these wastes as a result of
equipment cross-contamination. Thus,
the Agency anticipates including
standards for these constituents in all of
the treatment standards for the listed
wood preserving wastes.

0. Finally, EPA has decided to stay
the listing of wastewaters so that the
listing applies only to wastewaters that
have come in contact with process
contaminants, i.e., wood preservif
solutions, spent preservatives, anc
like. It is these process contaminants
that make the wastewater hazardous.
and the Agency did not intend for the
listing to apply to uncontaminated
wastewaters (see 56 FR 21955. May 13.
1991). Thus, if wastewaters are kept
uncontaminated. they will not be (and
should not) be covered by the listing.
EPA intends to initiate rulemaking to
determine whether to make this a
permanent regulatory change.
Any wood preserver claiming that
wastewater has not come in contact
with process contaminants would have
the burden of proving that this is the
case. This is because the details of plant
operation, and in particular wastewater
management, are within the special
knowledge of the wood preserving
facility. See 50 FR at 643 (January 4.
1985) and cases there cited. The best
(and perhaps only) way of showing no
contamination would be to segregate
uncontaminated waters (for example.
non-contact cooling water) from normal
process wastes and process areas. Such
segregation also serves a useful waste
minimization function by reducing the
total volume of contaminated
wastewater. Thus, the Agency vu
today's action as creating an incc
for waste minimization. Conversely.
however, the Agency notes that if
initially uncontaminated wastewater is
mixed with contaminated wastewater
(as in a centralized wastewater
treatment system) or with process
contaminants (such as rainwater falling
on a process area drip pad), then the
entire volume of wastewater is
hazardous because of the mixture rule.
E. EPA is issuing this administrative
stay pursuant to 5 U.S.C 705 which
provides that an agency may postpone
the effective date of action taken by it
when justice so requires, pending
judicial review.1 The Agency believes
that this standard is satisfied here
because it appears to be legitimately
infeasible for a significant number of
wood preserving facilities to comply
with the drip pad standards by June 6.
In addition, the sealant requirement
for new drip pads appears unnecessary
and could add to the time needed to
comply with drip pad standards.
Inclusion of potentially cross-
contaminated wastes within the F032
listing does not serve any direct

regulatory jHPpase (given the uniform
revelatory standards ter FW2. F084, and
F035 wastes), and cauiei o«we facilities
to be subject to the June 6 effective date
with which they may be unable to
comply. Inclusion of uncontaminated
wastewaters within the scope of the
listing is not necessary to further any
legitimate environmental objective, and
so should legitimately be stayed.
At the same time, the administrative
stay is structured so as to prevent
environmental abuses from uncontrolled
drrppage during the pendency of the
stay, and is further structured to be
available only to facilities making bona
fide efforts to comply. A significant
number of wood preservers thus could
be harmed irreparably should the drip
pad standards take effect on June 6. Trie

to allow time for clean-up of drippage

also assures that the stay will be in the
public interest. The Agency
consequently find* that issuing this stay
is in the interests of instice.*
VII. Effects on State Authorisatian
The effects of the administrative stay
depend tacgery an whether the fadtity is
managing a wood preserving waste
identified by a HSWA-based listing (i.e..
the F032 wastes), as opposed to the
newly listed wastes (F034 and F035) for
which the fating derernrtnarions were
based on pre-HSWA authority.
As explained earlier. EPA considers
that both the F032 listing and the new
subpart W drip pad standards (whea
applied to the management of F032
wastes) are based on HSWA authority.
As EPA explained in the December 8.
1990 notice (see 55 FR 50469), the
HSWA-based F032 listing and related
subpart W facility standards take effect
simultaneously in all States, regardless
of their authorization status. With
respect to these HSWA-based
requirements, the effect of the
administrative stay is to defer in all
States EPA's implementation end
enforcement of these requirements

the a&HBMkrstte* ate? eebeMe.
According to the schedule for State
prognnn revisions cunteiiieu rn 40 Crit
271.21(e), the December 0,1990 Wood
Preservation Rule is subject to • My t.
1992 deadline (July 1,1993 if a statutory
change is required) for States to modify
their hazardous waste programs and
thereafter seek approval from EPA for
the program revision. Since the
administrative stay would not extend
any effective dates beyond May 6,1992.
EPA considers it very unlikely that any
State wnl have teceived approval fium
EPA to implement the December 6,1990
regulation ander RCRA authority with
earlier or more stringent effective dates
than those set out in this stay.
Nevertheless, States may Btodify their
hazardous waste programs to adopt the
Wood Preservative Rote in the interim.
While EPA encourages States to follow
the deferred affective dates announced
ia tilts stay. States may elect to
implement the role with effective dates
earlier than those imposed under this
stay, as a matter of State law.
In tne case of facilities managing FOM
and F035 wastes, the effect of the stay
depends on whether the facility is
located in aa authorized or unauahacned
State. The FOM and P035 fisting
determinations were promulgated
pursuant to pre-HSWA authority, and
EPA considers the sobpart W drip pad
standards that govern the mamgesneat
of F034 and F035 wood preserving
wastes to also be baaed on pre-HSWA
authority. According to the December 8.
1990 Rule notice, these wastes listings
and facility standards would have been
effective on June 6.1991 only in those
States that are not authorized for any
part of RCRA. EPA implements the
RCRA program in unauthorized Staiee,
and the affect of this slay will be to
defer EPA'a Jmpleiaentatioa aad
enforcement of the Wood preserving
Rule's F034 and F035 provisions m
accordance with the administrative stay
schedule.
In authorized States, the pre-HSWA
basis for the F034 and F035 listings {and
related subpart W drip pad standards)
means that these requirements cannot
be implemented as RCRA requirements
until the State has adopted the
necessary program modifications and
obtained approval for the necessary
program modifications and obtained
approval for the revisions from EPA.
The modification schedule in 40 CFR
271.20(e) requires that States modify
their programs by fuly 1.1992 (July 1.
1993 if a statutory change is required) to
adopt this regulation and thereafter seek
approval of the revisions from EPA,
Since the stay does not extend any
effective dates beyond May «, M92. it is
unlikely tsjet States will become
authorized far the FB34 and FW5 listMgs
and facility standards before the
deferred effective dates in the stay aa ve
already passed. However, facilities in
both authorized states and unauthorized
states should understand (hat slates
may adopt and implement wood
preserving regulations w a matter cf
state law, prior to obtaining EPA
approval. While EPA strongly
encourages States to fallow the deferred
effective dates announced in this stay.
States may elect to adopt wood
preserving w«ste regulations with more
stringent (e.g.. eertierj effective dates
than those atmonnced in this
administrative stay.

1 StATS is the State Authorization Tracking System which tracks States' progress in becoming
authorized for each checklist. This column was added to help the Regions and States relate data
entered in that system with the information included in this table. The "rule code" is the symbol used
in StATS to represent a particular rule or non-checklist item, e.g., State Availability of Information or
Fladioactive Mixed Waste.

3A parenthesized number implies that this is not the main rule for the indicated checklist.
However, the rule is included on the indicated checklist. Rules with parenthesized numbers are
typically technical corrections or amendments to a major final rule. These corrections are usually
close enough in time to the initial final rule that the correction was included on the checklist for the
initial rule, rather than developing a new checklist for the correction.
4While Revision Checklists 27 and 43 are optional, States which have adopted or choose to
adopt the changes addressed by Revision Checklist 27 must adopt Revision Checklist 43's changes.
5The May 2, 1986 amendments to 40 CFR 264.113 and 265.113, addressed by Revision
Checklist 24, must be adopted before or simultaneous with adopting the provisions addressed by
Revision Checklist 64. Also see Footnote 6.
6Note that, unlike other checklists which address more than one final rule, Revision Checklist 70
is not represented by each of its rules in StATS. Instead, it is represented only once as Revision
Checklist 70, rather than five separate rules. The rationale for this representation is that this checklist
is very different from the others in the program, because it represents an accumulation of small
changes to Part 124, relating to the RCRA program, spanning the six-year period from 1983 to 1989.
7Only those sections, i.e., 40 CFR 264.113 and 265.113, of Revision Checklist 24 (Amended)
recharacterized as more stringent by the June 26, 1990 correction are included in Non-HSWA Cluster
VI. All other Revision Checklist 24 provisions continue to be included in Non-HSWA Cluster II.
States which have already adopted the 264.113 and 265.113 amendments as part of their
authorization for Revision Checklist 24 in Non-HSWA Cluster II, are not affected by this correction and
do not have to submit an amended Revision Checklist 24.
3Revision Checklist 78 is in HSWA Cluster II, with the exception of the clarifying amendment to
§268.33(c) which is in Non-HSWA Cluster VI. This clarification is not immediately effective in
authorized States since the requirements are not imposed pursuant to HSWA. Thus, these
requirements are applicable only in those States that do not have interim or final authorization. In
authorized States, the requirements will not be applicable until the State revises its program to adopt
equivalent requirements under State law.
9Direct Action against insurers in RCRA §3004(t) is not delegable to the States. EPA realizes
that six States are currently "authorized" for this provision. Several States have included this
provision in their pending HSWA I revision applications. The Regions should review these provisions
and clarify with their States that, by virtue of the statute, the Federal cause of action ensured by
RCRA §3004(t) remains in effect in authorized States. This provision is not delegable because
authorized provisions of State law must operate in lieu of the Federal counterpart and, in this
situation, State law providing for a direct cause of action against insurers may augment the Federal
Action, but not supersede it.

1 Direct Action against insurers in RCRA §3004(t) is not delegable to the States. EPA realizes
that six States are currently "authorized" for this provision. Several States have included this
provision in their pending HSWA I revision applications. The Regions should review these provisions
and clarify with their States that, by virtue of the statute, the Federal cause of action ensured by
RCRA §3004(t) remains in effect in authorized States. This provision is not delegable because
authorized provisions of State law must operate in lieu of the Federal counterpart and, in this
situation, State law providing for a direct cause of action against insurers may augment the Federal
Action, but not supersede it.
2Only those sections, i.e., 40 CFR 264.113 and 265.113, of Revision Checklist 24 (Amended)
recharacterized as more stringent by the June 26, 1990 correction are included in Non-HSWA Cluster
VI. All other Revision Checklist 24 provisions continue to be included in Non-HSWA Cluster II.
States which have already adopted the 264.113 and 265.113 amendments as part of their
authorization for Revision Checklist 24 in Non-HSWA Cluster II, are not affected by this correction and
do not have to submit an amended Revision Checklist 24.
3While Revision Checklists 27 and 43 are optional, states which have adopted or choose to
adopt the changes addressed by Revision Checklist 27, must adopt Revision Checklist 43's changes.
4The May 2, 1986 amendments to 40 CFR 264.113 and 265.113, addressed by Revision
Checklist 24, must be adopted before or simultaneous with adopting the provisions addressed by
Revision Checklist 64. Also see Footnote 1.

5Revision Checklist 78 is in HSWA Cluster II, with the exception of the clarifying amendment to
§268.33(c) which is in Non-HSWA Cluster VI. This clarification is not immediately effective in
authorized States since the requirements are not imposed pursuant to HSWA. Thus, these
requirements are applicable only in those States that do not have interim or final authorization. In
authorized States, the requirements will not be applicable until the State revises its program to adopt
equivalent requirements under State law.
6The rule addressed by this checklist is a technical amendment to the final rule (53 FR 43881;
October 31, 1988; Revision Checklist 57)) that removed strontium sulfide from 40 CFR 261.33, the list
of commercial chemical products which are hazardous wastes when discarded or intended to be
discarded. States which intend to remove strontium sulfide from their hazardous wastes lists, but
have not yet adopted the changes made by Revision Checklist 57 are strongly encouraged to adopt
the changes addressed by Revision Checklists 57 and 86 at the same time. Those States that have
already adopted the Revision Checklist 57 provisions should adopt the Revision Checklist 86
amendments as soon as possible. States should note that Revision Checklist 86 is a conditionally
optional checklist. States choosing not to adopt the removal of strontium sulfide (i.e. Revision
Checklist 57) should not adopt the Revision Checklist 86 provisions. However, States which choose
to remove strontium sulfide must adopt the provisions addressed by Revision checklist 86 to be sure
that the material has been properly removed from the State's lists and appendices.

C. [This requirement applies only if States have a delisting mechanism. This
requirement is NOT OPTIONAL for such States.] State statutes and regulations provide
authority to delist hazardous waste as indicated in Revision Checklist 17 B.
(1) State statutes and regulations require that before deciding to delist a waste,
the State must consider whether any listing factor (including additional
constituents) other than those for which the waste was listed would cause
the waste to be hazardous.
Federal Authority: RCRA §3001 (f)(1); 40 CFR 260.22 as amended July 15, 1985 (50 FR
28702) and June 27, 1989 (54 FR 27114).
(2) State statutes and regulations require that there be no new temporary
delistings without prior notice and comment. All temporary delistings received
before November 18, 1984 without the opportunity for public comment and
full consideration of such comment, shall lapse if not made final by
November 8, 1986.
Federal Authority: RCRA §3001 (f)(2); 40 CFR 260.20(d) as amended July 15, 1985 (50
FR 28702).
Citation of Laws and Regulations: Date of Enactment and Adoption
Remarks of the Attorney General
D. [OPTIONAL: This is a reduced requirement.] State statutes and regulations
define hazardous waste so as to exclude waste pickle liquor sludge generated by lime

newly listed wastes, four wastes that fall into the F002 and F005 (spent solvent) waste
codes, F025, mixed radioactive/hazardous wastes, characteristic wastes, and multi-source
leachate, as well as establish revised treatment standards for petroleum refining hazardous
wastes (K048-K052) as indicated in Revision Checklists 78 and 83.
"Soft hammer" wastes are those wastes for which EPA did not promulgate treatment
standards by their respective effective dates. These wastes could continue to be
disposed of in a landfill or surface impoundment until May 8, 1990 if certain
demonstrations were made and the technology requirements of RCRA §3004(o)
were met. Other types of land disposal (e.g., underground injection) were not
similarly restricted. On May 6, 1990, wastes for which EPA had not established
treatment standards became prohibited from all types of land disposal. This latter
requirement is referred to as the "hard hammer" provision and ended the soft
hammer provisions which were in effect prior to May 6, 1990.

CONSOLIDATED CHECKLIST
•-. for the
Land Disposal Restrictions as of June 30, 1991
1) This checklist consolidates the changes to Federal code addressed by the following Land Disposal
Restrictions (LDR) checklists: Revision Checklist 34 [51 FR 40572 (November 7, 1986), 52 FR 21010
(June 4, 1987)]; Revision Checklist 39 [52 FR 25760 (July 8, 1987), 52 FR 41295 (October 27,
1987)]; Revision Checklist 50 [53 FR 31138 (August 17, 1988); 54 FR 8264 (February 27, 1989)];
Revision Checklist 62 [54 FR 18836 (May 2, 1989)]; Revision Checklist 63 [54 FR 26594 (June 23,
1989)]; Revision Checklist 66 [54 FR 36967 (September 6, 1989), 55 FR 23935 (June 13, 1990)];
Revision Checklist 78 [55 FR 22520 (June 1, 1990)]; and Revision Checklist 83 [56 FR 3864 (January
31, 1991)]. The "LDR Checklist Reference" column indicates which of these checklists have affected
each listed citation. Subsequent to promulgation of the first LDR rule (i.e., the rule addressed by
Revision Checklist 34), checklists other than the LDR checklists have also affected certain sections of
code addressed by the LDR checklists. The effects of these subsequent checklists are indicated in
footnotes. Of special note are 270.42(o)&(p) and 270.72(e). In both cases, subsequent checklists
eiither removed or redesignated these sections of code. The section numbering found in the
associated LDR final rule for these paragraphs is used, rather than the new numbering found in the
subsequent checklists.
An exception to the footnoting procedure is the effect which the Toxicity Characteristics Rule had on
the TCLP procedure. Because the new TCLP procedure is integral to the Third Third Rule
requirements (see Note 6 below), this change made by Revision Checklist 74, a non-LDR checklist, is
(noted in the LDR checklist reference column. An explanatory footnote is also included.
2) The following Part 268 sections are not delegable to States because of the national concerns
which must be examined when decisions are made relative to them: 268.5 (case-by-case effective
date extensions); 268.42(b) (application for alternate treatment method); and 268.44 (variance from a
treatment standard). "No migration" petitions under 268.6 will be handled by EPA, even though
States may be authorized to grant such petitions in the future. States have the authority to grant
such petitions under RCRA Section 3006 because such decisions do not require a national
perspective, as is the case for decisions under 268.5, 268.42(b) or 268.44. However, EPA has had
few opportunities to implement the land disposal restrictions and expects to gain valuable experience
and information from reviewing "no-migration" petitions.
3) In the past, the nondelegable sections/paragraphs of the LDR regulations have been omitted from
ttie LDR checklists because States could not assume the authority for them. However, this procedure
has led to confusion among the States on how to handle the sections/paragraphs in their code. For
this reason, the Agency has decided to include these nondelegable sections on the LDR checklists.
To differentiate these sections from the delegable portions of the LDR restrictions, asterisks precede
(a single row) and follow (a double row) each non-delegable section. If States have already filled out
a version of this Consolidated Land Disposal Restriction Checklist which does not include the
nondelegable sections, they need not fill out a revised version containing these sections. This change
in format was made only to improve clarity.

OSWER DIRECTIVE NO. 9541.00-17
CONSOLIDATED CHECKLIST: Land Disposal Restrictions (cont'd)
The Agency suggests that States incorporate the nondelegable portions of the LDR regulations into
their regulations because this incorporation aids the regulated community in knowing that the
extensions, exemptions and variances addressed by the nondelegable sections of code are available
to them. It is essential, however, that States leave the terms "Administrator", "Federal Register" and
"Agency" unchanged, i.e., States may not substitute analogous State terms for these Federal terms.
Similarly, States incorporating by reference must be careful to exclude these sections from blanket
substitutions of State terms for Federal terms. For a more complete discussion of issues surrounding
nondelegable sections, see Appendix J of the State Authorization Manual (SAM).
4) Note that while 268.40 is delegable to States, "Administrator" in the following phrase "Approved by
the Administrator under the procedures set for this in 268.42(b)" should not be replaced with an
analogous State term because it is referring to decisions under 268.42(b). Such decisions will be
made by the EPA Administrator.
5) States do not need to adopt requirements equivalent to 40 CFR 268.10, 268.11, 268.12 and
268.13 because these sections of code contain the schedule by which EPA must evaluate wastes for
land disposal restrictions. As such, these sections of code are not included in this consolidated
checklist.
6) Note that the Toxicity Characteristic Leaching Procedure (TCLP) referred to by the Third Third
Scheduled Waste Rule is the TCLP entered into the Federal code at 40 CFR 261 Appendix II by the
Toxicity Characteristic Rule (55 FR 11798, March 29, 1990) and amended at 55 FR 26986 (June 29,
1990). (Both the Toxicity Characteristic Rule and the June amendment are addressed by Revision^
Checklist 74.) The TCLP procedure previously located at 40 CFR Part 268, Appendix I and
introduced by the Solvents and Dioxins Land Disposal Restrictions Rule (51 FR 40572; November 77"
1 986; Revision Checklist 34) is the outdated version of the TCLP. Thus, States adopting the Third
Third Scheduled Waste Rule must also adopt the new version of the TCLP. If a State has already
adopted the Revision Checklist 34 TCLP, this version must be replaced with the Revision Checklist 74
TCLP. See Footnote 41 of this checklist.
7) Guidance regarding the use of the new TCLP versus the EP Toxicity Test may be found at 55 FR
22660 (June 1 , 1 990). The code (40 CFR 268.41 (a)) addressing this issue contains a serious
technical error which is discussed in Footnote 36 found at the e.nd of this checklist.
8) Adopting the alternate treatment standards for lab packs is optional. However, if a State chooses
to adopt these alternate standards, all of the requirements related to these standards must be
adopted, including all of the provisions added by the Third Third Scheduled Waste Rule (i.e., Revision
Checklist 78) at 264.31 6(f), 265.31 6(f), 268.7(a)(8), 268.7(a)(9), 268.42(c), 268.42(c)(1)-(4), and
Appendices IV and V to Part 268.

See amendment to rule addressed by Revision Checklist 39 at 52 FJR 41295 (October 27, 1987).
Paragraph 260.11 (a) is also affected by Revision Checklist 67 (54 FR 40260, September 29,
1989) and Revision Checklist 73 (55 FR 8948, March 9, 1990).
Paragraph 261.5(f)(2) is also affected by Revision Checklist 47 (53 FR 27162, July 19, 1988).
Note that the "TC Rule," Revision Checklist 74 (55 FR 11798, March 29, 1990), has also made
changes to 261.24(b).
Paragraph 261.33(c) is also affected by Revision Checklist 41 (52 FR 26012, July 10, 1987).
Note that the final rule for Revision Checklist 39 (52 FR 25787) gives Subpart E, 262.51 as the
citation for Farmers. This is not correct as the August 8, 1986 (51 FR 28664, Revision Checklist
31) final rule regarding exports changed this section and moved it to Subpart G, 262.70. This
error in the final rule was deleted when Revision Checklist 39 was developed, and the proper
citation (262.70) was used on that checklist. This error was ultimately corrected at 53 FR 27164
(July 19, 1988).
Also see technical correction to the rule addressed by Revision Checklist 34 at 52 FR 21010
(June 4, 1987).
Subparagraphs 264.13(a)(1) and 265.13(a)(1) are also affected by Revision Checklist 64 (54 FR
33376, August 14, 1989).
This code is part of the optional requirements for the alternate treatment standards for lab packs
under the Third Third Scheduled Waste Rule. If adopted, all of the requirements (i.e., 264.316(f),
265.316(f), 268.7(a)(8), 268.7(a)(9), 268.42(c), 268.42(c)(1)-(4), and Appendices IV and V to Part
268) related to these alternate treatment standards must be adopted.

A new subparagraph was introduced into the code by Revision Checklist 78. The original
subparagraph 268.1 (c)(3) was introduced by Revision Checklist 34, modified by Checklist 39, then
removed by Revision Checklist 50, with 268.1 (c)(4) redesignated as (c)(3). The redesignated
subparagraph 268.1(c)(3) was subsequently removed by Revision Checklist 66.
Subparagraph 268.1(c)(4) originated in Revision Checklist 34, was modified by Revision Checklist
39, redesignated as 268.1 (c)(3) while the original 268.1 (c)(5) was redesignated as 268.1 (c)(4) by
Revision Checklist 50, and finally removed by Revision Checklist 66.
Subparagraph 268.1 (c)(5) originated in Revision Checklist 39, and was revised by Revision
Checklist 48. This text was redesignated as 268.1(c)(4) and new 268.1(c)(5) text was introduced
by Revision Checklist 50. This subparagraph was finally removed by Revision Checklist 78.
These definitions were introduced into the code as part of 268.2(a) by Revision Checklist 34.
Revision Checklist 78 designated them as individual paragraphs 268.2(b) and (c). The text of the
old 268.2(b), introduced into the code by Revision Checklist 34, was deleted from the section by
Revision Checklist 78.
This definition was introduced into the code as part of 268.2(a) by Revision Checklist 39.
Revision Checklist 78 designated it as an individual paragraph 268.2(e).
This subparagraph was originally 268.3 when it was added to the code by Revision Checklist 34.
However, it was redesignated as 268.3(a) by Revision Checklist 78.
268.6(c) was originally introduced by Revision Checklist 34. Revision Checklist 50 redesignated
that 268.6(c) as 268.6(d) and inserted a new 268.6(c).
The original 268.6(d) was introduced by Revision Checklist 34. Revision Checklist 50
redesignated that paragraph as 268.6(g). That same checklist redesignated 268.6(c) as 268.6(d).
268.6(e) was introduced by Revision Checklist 34. Revision Checklist 50 redesignated that
268.6(e) as 268.6(h) and inserted a new 268.6(e).
268.6(f) was introduced by Revision Checklist 34. Revision Checklist 50 redesignated that 268.6(f)
as 268.6(i) and inserted a new 268.6(f).
268.6(d)-(j) were originally introduced by Revision Checklist 34. Revision Checklist 50
redesignated these paragraphs as 268.6(g)-(m).
268.6(k) was originally introduced by Revision Checklist 39. Revision Checklist 50 redesignated it
as 268.6(n).
Note that the rule addressed by Revision Checklist 78 (55 FR 22520) makes it appear as if
268.7(a)(3)(iii)-(v) were removed (see page 22687). This was~ an error and these subparagraphs
should remain in the code.

Initially, subparagraphs 268.7(a)(4)(i)-(iv) were introduced into the code by Revision Checklist 50.
Revision Checklist 78 completely changed the text of (a)(4)(i)-(iii) and removed (a)(4)(iv).
24 This subparagraph was originally 268.7(a){4) when it was added to the code by Revision Checklist
34. However, it was redesignated as 268.7(a)(5) by Revision Checklist 50.
25 268.7(a)(7) was originally 268.7(a)(6) on Checklist 50. Revision Checklist 83 inserted a new
268.7(a)(6) and redesignated the old 268.7(a)(6) as 268.7(a)(7). Revision Checklist 83 also
redesignated 268.7(a)(7)-(a)(9) as 268.7(a)(8)-(a)(10).
26 These subparagraphs were originally 268.7(b)(1) and 268.7(b)(1)(i)-(iv) when they were added to
the code by Revision Checklist 34. However, they were redesignated as 268.7(b)(4) and
268.7(b)(4)(i)-(iv) by Revision Checklist 50.
27 These subparagraphs were originally 268.7(b)(2) and 268.7(b)(2)(i)-(ii) when they were added to
the code by Revision Checklist 34. However, they were redesignated as 268.7(b)(5) and
268.7(b)(5)(i)-(ii) by Revision Checklist 50.
28 This paragraph was originally 268.7(b)(8) when it was entered into the code by Revision Checklist
50, but it was redesignated as 268.7(b)(7) by Revision Checklist 78 because the old 278.7(b)(7)
and 278.7(b)(7)(i)-(iv) were removed by Revision Checklist 78. Revision Checklist 66 corrected
268.7(b)(8) before it was redesignated by Revision Checklist 78.

*•* The notice, certification and test requirements currently found in Federal code at 268.7(c)(1) and
(c)(2) were originally addressed in paragraph 268.7(c), as introduced into the code by Revision
Checklist 34. 268.7(c) was subsequently modified by Revision Checklists 39 and 50. Revision
Checklist 39 added the testing requirements now found at 268.7(c)(2), although at the time these
requirements were still part of 268.7(c). It was Revision Checklist 50 that significantly revised the
paragraph so that the notice and certification requirements now appear at (c)(1) and the testing
requirements appear at (c)(2). The checklist reference column, then, includes all relevant
checklists for 268.7(c)(1) and (c)(2), rather than just Revision Checklist 50 which primarily affected
the formatting.
on
Subparagraphs 268.7(c)(3) and (c)(4), introduced into the code by Revision Checklists 50 and 66,
respectively, were removed from the code by Revision Checklist 78.
31 An error in the September 6, 1989 rule (54 FR 36967) makes it appear that the revisions to
268.8(a) include the removal of 268.8(a)(4). This was not the Agency's intent and 268.8(a)(4)
remains in Federal code as introduced by Revision Checklist 50.
OO
0 The 268.30(a) introduction appeared in the final rule addressed by Revision Checklist 50, but was
not changed by that rule. See Revision Checklist 50 for more information.
33 These subparagraphs were originally 268.30(c) and 268.30(c)(1)-(3) when they were introduced
into the code by Revision Checklist 34. However, Revision Checklist 50 redesignated them as
268.30(d) and 268.30(d)(1)-(3) because that checklist inserted a new paragraph at 268.30(c).

These subparagraphs were originally 268.31 (b) and 268.31 (b)(1)-(3) when they were introduced
into the code by Revision Checklist 34. However, Revision Checklist 50 redesignated them as
268.31 (d) and 268.31 (d)(1)-(3) because that checklist inserted a new paragraph at 268.31 (b).
35 While this subparagraph appeared in the final rule addressed by Revision Checklist 50, this rule
did not change this subparagraph. See Footnote 9, page 28 of Revision Checklist 50.

The current text of 268.41 (a) indicates that an extract or treatment residue of certain wastes may
be land disposed only if certain requirements are met using either the test method in Appendix I
of Part 268 or the test method in Appendix II of Part 261. Following promulgation of the March
29, 1990 Toxicity Characteristics rule addressed by Revision Checklist 74 (55 FR 11798, as
amended at 55 FR 26986), both of these appendices relate to the same test method, the TCLP.
Previously, the Part 261 appendix contained the EP Toxicity test procedures while the Part 268
appendix contained the TCLP. EPA will issue a correction to the rule for these particular
paragraphs in the near future, clarifying which procedures may be used. Until such time,
however, EPA indicates that for the specific waste exceptions listed in these paragraphs, the
TCLP can be used for measuring compliance with the treatment standards for those specified
wastes, and if the extract or treatment residue fails that test, the EP Toxicity test can be used. If
the extract or residue passes that less stringent test, then such waste is considered in compliancy
with the treatment standards. For more information related to the use of either of the two test
methods, see the discussion at 55 FR 22660 (June 1, 1990).
3 268.42(a)(3) was introduced into the code by Revision Checklist 63. Revision Checklist 78
removed this paragraph and Revision Checklist 83 added a new 268.42(a)(3).
38
268.42(a)(4) was introduced into the code by Revision Checklist 63. Revision Checklist 78
removed this paragraph.
39
3 The 55 FR 22520, June 1, 1990, code incorrectly states that a subparagraph 268.42(e) is added.
The Federal Register did not contain a 268.42(e); it only added 268.42(d).
While 268.43(b) appeared in the final rule addressed by Revision Checklist 63, the text of the
paragraph was not changed and remains the same as that introduced by Revision Checklist 50.
As background, the TCLP was originally promulgated in 268, Appendix I, on November 7, 1986
(51 FR 40572; Revision Checklist 34) for use in the Land Disposal Restrictions (LDR) program to
determine whether certain wastes require treatment prior to land disposal and to determine
whether certain treated wastes meet the applicable treatment standards. The TC rule and its
June 29, 1990 modification promulgated a revised TCLP at 261, Appendix II, with modifications
based on the Agency's own research and public comment. This TCLP is to be used in both the
TC and the LDR programs. The objective of the above footnoted revision to 268, Appendix I, is
to assure that the TCLP entered into the code by the November 7, 1986 notice (51 FR 40572;
Revision Checklist 34) is removed and replaced by the TCLP entered into the code and amended
by the final rules (55 FR 11798 and 55 FR 26986) addressed by Revision Checklist 74. The
actual placement of the TCLP within a State's code is not that important, per se; what is imporjiit
is that a State's code contains only the Revision Checklist 74 TCLP.

Paragraphs 270.42(o) and (p) were introduced into the code by Revision Checklists 34 and 39,
respectively. Subsequently, Revision Checklist 54 removed both paragraphs, though these
deletions were optional. Though EPA strongly encourages States to adopt the permit modification
rule as addressed by Revision Checklist 54, States may elect to retain paragraphs 270.42(o) and
(p). Thus, the paragraphs are included in this consolidated checklist. If States have adopted the
Revision Checklist 54 modifications, the section title should also be modified to read "Permit
Modification at the Request of the Permittee" instead of "Minor Modifications of Permits" and the
Revision Checklist 54 modifications made. States should also note that 270.42 was not required
by 271.14 to be part of a State's authorized permit program. Thus, only States which elected to
have a section analogous to 270.42 (Minor Modifications of Permits) at the time of base program
authorization need worry about the 270.42 modifications made by Revision Checklists 34 and 39.
These changes are, of course, negated if the State chooses to also adopt the Revision Checklist
54 modification.
Appendix I was introduced by Revision Checklist 54 as an optional modification to Section 270.42.
Changes to this appendix addressed by the LDR Revision Checklist 78 are relevant only if a State
has modified its code to include Appendix I as per Revision Checklist 54.
Revision Checklist 78 redesignated item B(1)(b) as item B(1)(c) and added a new B(1)(b).
This item was entered into the code as Appendix I, B(1)(b) and was redesignated as B(1)(c) by
Revision Checklist 78.
Revision Checklist 61 revised and redesignated 270.72(e) as 270.72(b). The Revision Checklist
61 changes are optional, however, some States may have retained 270.72(e) in their code as
introduced by the LDR Revision Checklist 39.
