                               EXECUTIVE  SUMMARY

     This  document  supports  the  final  rule  for  the  Third Third of the wastes
scheduled for restriction from land disposal under section 3004(m) of  the
Resource Conservation and Recovery Act (RCRA) as amended by the Hazardous and
Solid Waste Amendments of 1984 (HSWA)   It presents the estimates of the
quantities of wastes that will require alternative treatment and recovery
prior to land disposal.  It also presents estimates of alternative treatment
and recovery capacity available to manage wastes restricted from land
disposal, taking into account the demands already placed on that capacity by
previous land disposal restrictions.

     To date,  the  Land Disposal  Restriction Program has  promulgated  final
rules on the land disposal (treatment or storage in waste piles; treatment,
storage, or disposal in surface impoundments; and disposal in landfills, land
treatment units, and underground injection) of solvent and dioxin-containing
wastes, California  list wastes, and wastes from the First Third and Second
Third of the "scheduled" wastes.   This final rule provides land disposal
restrictions for waste codes not regulated under the previous rules.

Legal Background

     The Hazardous  and Solid Waste  Amendments  (HSWA)  to  RCRA,  enacted  on
November 8, 1984, set basic new priorities for hazardous waste management.
Land disposal, which has been the most widely used method for managing
hazardous waste, is now the least preferred option.  Under HSWA, the U.S
Environmental Protection Agency (EPA) must promulgate regulations restricting
the land disposal of hazardous wastes according to a strict statutory
schedule.  As of the effective date of each regulation, land disposal of
untreated wastes covered by that regulation is prohibited unless it can be
demonstrated that there will be no migration of hazardous constituents from
the disposal unit for as long as the waste remains hazardous.

     HSWA's  schedule  divided hazardous wastes  into  three  broad categories
The first category, which contained wastes restricted under regulations issued
on November 7, 1986, includes generic solvent and dioxin wastes.  The second
category, whose final rule was issued on July 8, 1987, covers wastes

                                      E-l

-------
originally listed by the State of California and adopted intact within HSWA.
The "California list" comprises the following classes of wastes:  liquid
hazardous wastes with a pH of less than or equal to 2.0 (acidic corrosive
wastes); all liquid hazardous wastes containing free cyanides, various metals,
and polychlorinated biphenyls (PCBs) exceeding statutory concentration levels;
and all wastes (liquid, sludge, or solid) containing halogenated organic
compounds (HOCs) in concentrations greater than or equal to specified
statutory levels.  All other hazardous wastes fall into the last category,
referred to as "scheduled" wastes.  HSWA requires EPA to promulgate
regulations for these wastes on a timetable that would restrict at least
one-third of them by August 8, 1988, at least two-thirds of them by June 8,
1989, and the remainder by May 8,  1990, i.e., the First, Second, and Third
Third scheduled wastes, respectively.

      Under  the  Land Disposal  Restriction Program, EPA must identify  levels  or
methods of treatment that substantially reduce the toxicity of a waste or the
likelihood of migration of hazardous constituents from the waste.   Where
possible, EPA prefers to define treatment in terms of performance (i.e.,
levels  of treatment, expressed as a concentration of hazardous constituents in
residuals from treatment) rather than in terms of specific treatment methods.
HSWA requires, however, that levels specified in the regulations be
demonstrated and available.  Accordingly, EPA's standards are generally based
on the  performance  of the best demonstrated available technology (BOAT),  as
documented by treatment data collected at well-designed and well-operated
systems using that  technology, or are based on data derived from the treatment
of similar wastes that are as difficult or more difficult to treat.

      The land disposal restrictions are  effective immediately upon
promulgation unless  the Agency grants a national variance from the statutory
date because of a lack of available capacity.  For every waste group, EPA
considers, on a national basis, both the capacity of commercially available
treatment or recovery technologies and the quantity of restricted wastes
currently sent  to land disposal for which on-site capacity is not available.
If EPA  determines that adequate alternative treatment or recovery capacity  is
available for a particular waste or waste group, the land disposal restriction
goes  into effect immediately   If not, EPA establishes an alternative
                                      E-2

-------
effective date based on  the earliest  date on which adequate  treatment  or
recovery capacity will be available,  or  two-years, whichever  is  less.

Summary of Capacity Analyses  for Previous Rules

      Estimates  of the  need for,  and availability of,  alternative hazardous
waste management  capacity for previous land disposal restrictions rules are
described below.

Solvents and Dioxins

      EPA promulgated the first rule under the  Land Disposal  Restriction
Program on November  7, 1986  (51 FR  40572).  This rule established treatment
standards expressed  as concentrations in waste extracts for spent solvent
wastes  (F001-F005) and wastes contaminated with dioxin (F020-F023 and
F026-F028).  It prohibited  land disposal of wastes in these categories unless
they  contain less than the  specified  concentrations.

      EPA's  original  capacity analysis for solvent  wastes,  based  on  the RIA
Mail  Survey, indicated shortfalls in  available capacity for wastewater
treatment and incineration.   The Agency  therefore granted a two-year national
capacity variance for Comprehensive Environmental Response, Compensation,  and
Liability Act (CERCLA) wastes and RCRA corrective action wastes,  small
quantity generator wastes,  and all  wastes containing less than 1 percent total
F001-F005 solvent constituents.  When the initial analysis was later
reevaluated using TSDR Survey data, however, EPA found that capacity was
adequate for these wastes.

      The original capacity analysis for  dioxin-containing  wastes showed that
there was no available incineration capacity for these wastes.   The November
7, 1986, rule,  therefore, also granted a two-year national capacity variance
for these wastes.  Current  capacity estimates for these wastes are unchanged.

California List Wastes

      The California list defines  wastes  in terms of general  characteristics
rather  than waste codes.   It  covers classes of wastes originally listed by the
                                      E-3

-------
State of California and adopted intact within HSWA, including all liquid
hazardous wastes with a pH of less than or equal to 2.0 (acidic corrosive
wastes), all liquid hazardous wastes containing free cyanide, metals, or PCBs
in concentrations greater than or equal to limits specified in HSWA, and all
hazardous wastes (liquid, sludge,  or solid) containing HOCs in amounts greater
than or equal to limits specified in HSWA.

      EPA promulgated  its  final rule  on the California  list wastes on July  8 ,
1987 (52 FR 25760).  For HOC wastes,  EPA specified incineration as the
required treatment and did not set a concentration-based limit for treatment.
For PCB wastes, the Agency specified thermal  treatment  in accordance with 40
CFR 761.60 as the treatment standard.  For acidic corrosive wastes,  the Agency
prohibited all land disposal of wastes with a pH of less than or equal to 2.0,
but did not specify a treatment standard.   The final rule did not establish
prohibition levels for metal or cyanide wastes,  so the  prohibition limits
specified in the statute took effect.

      The capacity  analysis  for the California list rule was originally based
on the RIA Mail Survey, which indicated that  incineration capacity for HOC
wastes was inadequate.  The Agency had therefore granted a two-year national
variance for HOC wastes.  Capacity was found  to  be adequate for all other
California list wastes.  The HOC  variance  was rescinded on November 8,  1988,
however, because the later capacity analysis  using the  TSDR Survey found
incineration capacity to be adequate  and  the  variance unnecessary.

First Third Wastes

      EPA promulgated  the  final rule  for First Third wastes on August 17,
1988.  The capacity analysis conducted for First Third  wastes indicated that
adequate treatment capacity exists for all First Third  wastes except the
following:

      •     Petroleum refining wastes  (K048, K049,  K050, K051,
           K052),  for  which BOAT  is sludge incineration or solvent
           extraction;
      •     High zinc (greater than of equal to 15 percent zinc)
           electric arc furnace dust  (K061),  for which  BOAT is high
           temperature metals recovery; and
                                     E-4

-------
     •     Mercury cell chlorine production waste (K071), for which
           BOAT is acid leaching.

     The  Agency therefore granted two-year national  capacity variances  to  all
these wastes.   In the case of high zinc K061 wastes, however, it required
these wastes to be treated to meet the standard for  low zinc wastes based on
stabilization during the  variance period.

Underground  Injected Wastes

     EPA  has promulgated  three  final rules restricting  the  underground
injection of certain wastes.  The first final rule,  promulgated on July 26,
1988, addressed solvent and dioxin wastes.  Using the TSDR Survey data,  EPA
found that capacity was adequate for underground injected solvent wastes
containing greater than or equal to  1 percent total F001-F005 solvent
constituents, for which the BOAT technology was incineration; thus, no
variance was granted to these wastes.

     On the  other hand,  the  TSDR Survey  data  indicated  that  alternative
treatment capacity is inadequate for underground injected solvent wastes
containing less than or equal to 1 percent total F001-F005 solvent
constituents, for which the BDAT technology is wastewater treatment.   The
Agency  therefore  granted  a national  capacity variance for these wastes until
August  8, 1990.

     In addition,  the  Agency also found  that  no dioxin-containing  wastes are
being underground injected, so no alternative treatment capacity is required
for these wastes, and they were not  granted a capacity variance

     The  second final  rule,  promulgated  on August 16, 1988  (53  FR  30908),
addressed underground injection of California list wastes and certain First
Third wastes (K049-K052,  K062, K071, and K104).  This analysis showed
inadequate alternative treatment capacity  for almost all underground injected
California list wastes, the only exceptions being for liquid wastes containing
greater than 50 ppm PCBs  and liquid  and nonliquid wastes containing greater
than 1,000 ppm  of HOCs, all of which require incineration.  It also found that
alternative  treatment capacity is inadequate for all underground injected
First Third  wastes covered by the rule.  EPA therefore granted national
                                      E-5

-------
capacity variances until August 8, 1990, for all underground injected First
Third wastes and all underground injected California list wastes for which
treatment capacity is inadequate.

      On June  14,  1989  (54  FR  25416), EPA published  its  regulatory  approach
for underground injected First Third wastes not included in the August 16
rule.  Where BOAT standards had been promulgated under the First Third final
rule  (August 17, 1988), the approach proposed to adopt those standards by
reference.

      In the case  of  dilute K016 (<1 percent) wastewaters, EPA  found  that
insufficient capacity- exists for treatment and therefore granted a national
capacity variance.  In all other cases,  adequate treatment capacity exists for
all underground injected First Third wastes for which BDAT treatment standards
have been promulgated and EPA did not grant any other variances.

Second Third Wastes

      EPA published the  final  rule for Second Third wastes on June  23, 1989.
The capacity analysis conducted for this rule showed that sufficient capacity
exists to treat all wastes that are currently land disposed in surface units.
However, in order to allow time,  if needed, for modifications to treatment
systems, EPA delayed implementation of the cyanide standards for the
electroplating wastes (F006,  F007, F008, and F009) for 30 days.  In addition,
for heat treating wastes (F011 and F012),  EPA delayed implementation of the
cyanide standards until December 8,  1989.  to allow time for generators to
segregate these wastes for proper treatment.  Between July 8, 1989, and
December 8, 1989.  however, heat treating wastes were subject to the cyanide
standards applicable to electroplating wastes.

      For underground injected Second Third  wastes, the  capacity analysis
showed that capacity shortages exist for wastes requiring liquids combustion,
steam stripping followed by biological treatment,  and alkaline chlorination
and chemical precipitation.  Consequently,  EPA granted a two-year national
capacity variance to underground injected F007 wastes requiring alkaline
chlorination and chemical precipitation; K009 wastes requiring steam stripping
followed by biological treatment;  and K011, K013,  and K014 wastes requiring

                                      E-6

-------
liquids combustion.  Furthermore, in order to allow time, if needed,  for
modifications to treatment systems, EPA delayed implementation of  the  cyanide
standards for the electroplating wastes (F006, F007, F008, and F009)  for  30
days.  In addition, for heat treating wastes  (F011 and F012), EPA  delayed
implementation of the cyanide standards until December 8, 1989, to allow  time
for generators to segregate these wastes for proper treatment.  Between July
8, 1989, and December 8, 1989, however, heat treating wastes will be subject
to the cyanide standards applicable to electroplating wastes.

Third Third Rule

      EPA is  promulgating the  Third  Third  rule of  land disposal restrictions
(LDRs) to set treatment  standards for all Third Third wastes, including all
First Third and Second Third wastes that were "soft hammered," soil and
debris, multi-source leachate, and mixed radioactive wastes.

      For surface-disposed wastes,  the  capacity analysis  showed that
alternative capacity shortages exist for certain wastes requiring acid
leaching followed by chemical precipitation,  combustion of sludges and solids,
mercury retorting,  thermal recovery, and vitrification.   For deepwell-disposed
wastes, alternative capacity shortages exist for certain wastes requiring acid
leaching followed by chemical precipitation,  alkaline chlorination, biological
treatment followed by chemical precipitation, chemical oxidation followed by
chemical precipitation,  chemical oxidation followed by chromium reduction and
chemical precipitation,  chromium reduction followed by chemical precipitation,
mercury retorting, neutralization, and wet-air oxidation.  The comprehensive
lists of surface-disposed and deepwell-disposed wastes receiving variances are
found in Table 1 and Table 2.

      For soil and debris,  there  is  not enough treatment  capacity  for  wastes
whose BOAT is based on incineration, inorganic solids debris treatment,
mercury retorting and vitrification.  Therefore,  EPA is granting a national
capacity variance for all soil and debris whose BDAT is based on these
technologies.

     For multi-source leachate, the capacity analysis  shows  that  there is a
lack of capacity for the promulgated treatment technologies  for surface-
disposed nonwastewaters and deepwell-disposed wastewaters  containing organics
(i.e., combustion of sludge/solids, wet air oxidation  followed by  carbon
adsorption followed by chemical precipitation, and biological treatment
followed by chemical precipitation).  EPA is granting  a national capacity
variance to surface-disposed multi-source leachate organic nonwastewaters and
deepwell-disposed multi-source leachate wastewaters.

     For mixed radioactive wastes, EPA is granting a national capacity
variance for all wastes being surface-disposed.   EPA is not granting  a
variance for mixed radioactive wastes that are underground injected,  because
EPA currently has no information on these wastes.

Data Sources for the Current Capacity Analysis

TSDR Survey

     The TSDR Survey was originally mailed to approximately 2,400
RCRA-permitted or interim status facilities in August 1987.  Since that date,
an additional 225 new or previously overlooked facilities have been included.
To date,  over 2,500 surveys have been received,  reviewed for completeness and
accuracy,  and analyzed.

Generator Survey

     The  National Survey of Hazardous Waste Generators  (the Generator  Survey)
was designed to gather  data on waste generation  and exempt hazardous waste
treatment and recovery  capacity,  and it includes  detailed hazardous waste
characterization data.   For this  final  rule,  these data were used primarily to
verify generation of some  large volume  wastes and unique waste mixtures
reported  as  land disposed.

Leachate  Data

     The  Agency used two primary data sources to  perform the capacity  analysis
for multi-source leachate:   the TSDR Survey and  the Generator Survey.  The

                                     E-10

-------
Agency analyzed data on  the volumes of multi-source  leachate  generated  and
managed, including data  on the facility  schematics.  In addition  to  data
included in the surveys,  the Agency used additional  data from the hazardous
waste management industry submitted as part of  the leachate study plan.
(Appendix A describes these data sources in further  detail.)

Radioactive Waste Data

     The Department of Energy  (DOE) provided data on the generation  and
treatment of mixed radioactive wastes at 21 DOE facilities.   Information
sources for non-DOE mixed radioactive wastes included the TSDR Survey,
Generator Survey, published studies of mixed radioactive wastes, surveys and
reports for states and interstate compacts for managing low-level mixed
radioactive wastes, and  telephone contacts with government representatives and
industry officials.   (Appendix B describes these data sources)

Methodology for Capacity Analysis

     To evaluate the  adequacy  of alternative treatment capacity for  specific
waste categories, EPA first puts restricted wastes into "treatability groups"
that require  similar  treatment or management practices; for instance, all
wastes  requiring sludge  incineration would be placed in the same treatability
group.  Where  wastes  present particular  problems in  treatment, the Agency may
identify "treatment trains" of multiple  technologies operating in sequence.
Volumes of wastes in  each treatability group are adjusted to  reflect the
November 1988  deadline regarding minimum technology  requirements for surface
impoundments.  The net total volume of currently land disposed hazardous waste
requiring alternative treatment capacity becomes the required capacity  for
that treatability group.  EPA  then assigns the volumes of waste in each
treatability  group to treatment technologies or treatment trains.

     Determinations of available capacity take  several factors into  account.
Some treatment processes will  generate various  treatment residuals,  which then
have to be assigned to,  and accounted for within, other treatability groups.
Available capacity--the  difference between currently utilized capacity  and the
total capacity of the treatment system--must take into account the commercial
status  of each facility  managing waste within a treatability  group:

                                     E-ll

-------
     •    Available treatment capacity at on-site facilities used
          exclusively by the waste generator cannot be considered
          available to other generators;
     •    All commercially available capacity at commercial
          facilities is considered fully available to any generator

     Capacity analysis begins at the facility level and aggregates upward
toward the national level, assigning available excess capacity by observing
the above rules.  For example, available capacity at private treatment systems
applies only to wastes currently land disposed at the same site.  Remaining
wastes are assigned to commercial capacity.

     The analysis for each regulation within the Land Disposal Restriction
Program accounts for the sequential and cumulative effects of all previous
regulations and for projected capacity changes after 1986, as reported in the
TSDR Survey.  Solvents and dioxins were considered first,  followed by
California list wastes, First and Second Third promulgated wastes, and
finally, Third Third wastes.  Available capacity has been assigned first to
all affected surface disposed wastes and then to all underground injected
wastes.  EPA sets this priority because it believes that land disposal in
surface units may represent a greater threat to human health and the
environment than does underground injection.

Results of the Capacity Analysis

     For the types of treatment and recovery needed to meet Third Third rule
standards, Table 3 shows the commercial capacity remaining to manage all Third
Third wastes.  This takes into account the capacity already allocated to other
wastes under all previous land disposal restrictions.  Remaining capacity for
Third Third wastes is estimated by subtracting requirements for previously
restricted wastes from the capacity currently available.  This table
represents the most current data available to the Agency.

     In the Third Third proposed rule, EPA determined that 25 million gallons
of First Third Wastes required alkaline chlorination followed by chemical
precipitation.  This estimate was based on an analysis performed for the
                                     E-12

Second Third final rule to determine the volume of generated F006 wastes  that
may exceed the promulgated cyanide standards and therefore require treatment
for cyanides.  An analysis o'f the TSDR Survey data for the Second Third final
rule, showed that only 4 percent of F006 wastes that were genreated at TSDR
facilities may, as a worst-case scenario, contain cyanide concentrations  above
the revised standards.   Generator Survey data indicated that less than 2
percent of the volume of F006 at generator facilities have a cyanide
concentration above the treatment standard or had unknown concentration
levels.  In addition to analyzing the TSDR and Generator Survey data set,  EPA
also reviewed F006 data submitted by several commenters during the public
comment period for the Second Third rule.  One commenter submitted data
indicating that only 9 percent of 88 waste stream samples from a variety of
generators had total cyanide concentrations above the revised treatment
cyanide.  The second commenter's data showed that only 4 percent (2 out of 47
samples) had cyanide concentrations above the revised treatment standard.
Based on this data, EPA assumed for a worst-case analysis,  for the Second
Third final rule and the Third Third proposed rule,  that approximately ten
percent of cyanide waste streams would require treatment.   For the Third Third
final rule, EPA has revised the baseline estimate from ten percent to four
percent.  Consequently, the volume of First Third wastes requiring alkaline
chlorindation followed by chemical precipitation capacity has been revised.

     Using the remaining capacity for Third Third wastes as a baseline,
Table 4 shows the capacity needs for all Third Third wastes that are  not
underground injected (including leachate).  contaminated soils or debris,  or
mixed radioactive wastes.   This table shows that insufficient capacity
currently exists for some volumes of surface disposed Third Third wastes
Insufficient capacity exists for the following technologies:   acid leaching
followed by chemical precipitation,  sludge/solid combustion,  mercury
retorting,  thermal recovery, and vitrification.1  Consequently,  EPA is
granting variances to the following surface-disposed wastes:   D009,  K106,
P065, P092, and U151 low mercury nonwastewaters; F039 multi-source leachate
nonwastewaters; K048,  K049,  K050,  K051,  and K052 nonwastewaters;  D009,  K106,
        Volumes  of wastes assigned to these technologies have either technology-
based  or  concentration-based   treatment  standards.    Although  wastes  with
concentration-based  standards  can  be treated  with  other  technologies,  for
capacity analysis purposes,  volumes were  assigned to these BDATs.

P038, and U136 nonwastewaters.  EPA  is not granting a national capacity
variance for any other surface-disposed Third Third wastes.

     Table 5 allocates capacity to underground injected Third Third  wastes
after removing capacity  for surface-disposed wastes that are not receiving  a
variance.  The table shows shortfalls in available capacity for acid leaching
followed by chemical precipitation,  alkaline chlorination, biological
treatment  followed by chemical precipitation, chemical oxidation followed by
chemical precipitation,  chemical oxidation followed by chromium reduction and
chemical precipitation,  chromium reduction followed by chemical precipitation,
mercury retorting, neutralization, and wet-air oxidation.   As a result, EPA is
granting a two-year national capacity variance to the following underground
injected wastes:  D003 cyanide wastewaters and nonwastewaters; D003  sulfide
wastewaters and nonwastewaters; D003 explosive/reactive wastewaters  and
nonwastewaters; D007 wastewaters and nonwastewaters; D009 nonwastewaters; D002
wastewaters and nonwastewaters; K011 and K013 wastewaters, and K014
wastewaters and nonwastewaters; and  F039 multisource leachate wastewaters
EPA  is not granting a national capacity variance to any other underground
injected Third Third wastes.

     Table 6 allocates capacity to Third Third soil and debris wastes after
removing capacity for both surface-disposed and underground-injected wastes.
The  table  shows shortfalls in available capacity for incineration,  inorganic
solids debris treatment, mercury retorting, and vitrification.  As a result,
EPA  is granting an extension of the  effective date for certain First,
Second,and Third Third contaminated  soil and debris for which the treatment
standards  today are based on incineration, inorganic solids debris treatment,
mercury retorting or vitrification.

     Table 7 shows available treatment capacity for mixed radioactive wastes
and  the quantities requiring treatment.  The table shows shortfalls  for
available  capacity for stabilization, surface deactivation followed  by
encapsulation, combustion, incineration followed by ash stabilization,

injection of mixed radioactive wastes, EPA is not promulgating a national
capacity variance to those mixed radioactive wastes that are underground

indicating the capacity needs for  each surface disposed or underground

                                1.   INTRODUCTION

     This section  contains  a  brief  summary  of  the  legal background on the Land
Disposal Restriction  Program,  a summary  of  the results of capacity analyses to
support prior restrictions, and an  introduction  to  the capacity analysis for
those wastes analyzed for this final  Third  Third rule.

     Section 2 contains  the detailed  results of  the capacity analysis for the
Third Third final  rule.  Section  3  includes a  capacity analysis for each waste
code.  Section 4 details the  Agency's capacity analysis methodology   Section
5 lists the references used to prepare this document.

1.1  Legal Background

1.1.1     General  Requirements Under  HSWA

     The Hazardous and Solid  Waste  Amendments  of 1984 (HSWA),  enacted on
November 8, 1984,  amended the Resource Conservation and Recovery Act (RCRA) of
1976 in several significant ways.   Among other initiatives, the amendments
require the Environmental Protection  Agency (EPA) to promulgate regulations
restricting the land  disposal of  hazardous wastes according to a strict,
detailed schedule.  This effort is  generally referred to as the Land Disposal
Restriction Program.

1.1.2     Schedule for Developing Restrictions

     HSWA set a strict schedule for establishing treatment standards, based
generally on priorities  related to  the volume  and  intrinsic hazards of
different types of wastes.  Two groups received  early attention:  (1) solvent
and  dioxin wastes,  to be regulated  within 24 months of HSWA's passage, and (2)
the  so-called "California list" wastes,  to  be  regulated within 32 months   The
solvent/dioxin waste  group  identified in HSWA  includes those solvent wastes
covered under waste codes F001, F002,  F003, F004, and F005, as well as the
dioxin-containing  wastes covered  under waste codes  F020, F021, F022, and F023
(RCRA section 3004(e))   The  final  dioxin regulation also established
treatment standards for  F026,  F027, and  F028.
                                      1-1

-------
     The California list wastes, a  group  of wastes originally  listed  by  the
State of California and adopted  intact within HSWA,  include  liquid hazardous
wastes containing metals, free cyanides,  PCBs,  acidic  corrosives  (pH  of  less
than or equal to 2.0), and any liquid or  nonliquid hazardous waste containing
halogenated organic compounds (HOCs) above 0.1  percent (1,000  ppm) by weight.

     Priorities for all other hazardous wastes  listed  under  RCRA  section 3001
were established separately, based  on considerations of volume and  intrinsic
hazard, in a formal schedule submitted to Congress on  November 8, 1986 (RCRA
section 3004(g)(l)).  This schedule requires all  final land  disposal
restrictions to be in place by May  8, 1990.  Consistent with the  requirements
of HSWA, EPA divided all other listed hazardous wastes into  three groups (the
"Thirds"), to be regulated in successive  stages over a period  of  66 months
from the passage of HSWA on November 8, 1984.

      The overall schedule for the Land Disposal Restriction  Program is as
 follows:
      •    Solvents and dioxins:   Final  standards  promulgated on
           November 7,  1986.
      •    California list wastes:   Final  standards  promulgated on
           July 8,  1987.
      •    "First Third"  scheduled wastes:   Final  standards
           promulgated on August 8,  1988.
      •    "Second Third" scheduled wastes:   Final standards
           promulgated on June 8,  1989.
      •    "Third Third"  scheduled wastes:   Final  standards
           promulgated on May 8,  1990.

 1.1.3     Variance from the  Schedule

      The land disposal restrictions are effective when promulgated unless the
 Administrator grants a national capacity  variance and establishes a different
 date, not to exceed two years beyond the  statutory  deadline,  based on "the
 earliest date on which adequate alternative treatment or  recovery capacity
 which protects human health  and the environment will be available" (RCRA
 section 3004(h)(2)).  In addition,  case-by-case extensions  can be granted by
 EPA for up to one year (renewable once) from a ban  effective date if
                                      1-2

-------
applicants demonstrate alternative capacity is not available, and  that  they
have entered into a binding contract to construct or otherwise provide
alternative capacity

1.2  Summary of Previous Land Disposal Restrictions

     Capacity analyses to support previous land disposal restrictions were
performed using the best data available at the time to develop national
estimates of both the amount of waste land disposed and the available
alternative commercial treatment and recovery capacity.  Analyses of affected
wastes considered the combination of waste code, physical/chemical form, and
type of restricted management practice to determine the amount of alternative
capacity required.

1.2.1     Solvents and Dioxins

     The Land Disposal Restrictions Program began with the promulgation of the
solvents and dioxins rule on November 7, 1986 (51 FR 40572).  The final rule
included spent solvent wastes (F001-F005) and dioxin-containing
wastes (F020-F023 and F026-F028), and established treatment standards
expressed as concentrations in the waste extract.  The rule prohibits land
disposal of solvent and dioxin wastes unless the wastes contain less than the
specified concentrations of hazardous constituents.

     Initially. EPA used the 1981 Regulatory Impact Analysis (RIA) Mail
Survey1 to identify the volume of land disposed solvent wastes  subject to the
restrictions.  Although EPA did not establish required treatment technologies
for these wastes, EPA used the physical and chemical characteristics that were
reported for each waste stream to identify the technology or technologies that
EPA assumed would be used to meet the treatment standards.  The waste volumes
were distributed among the applicable technologies as shown below:

     After  identifying  the required alternative capacity for solvent wastes,
EPA analyzed the available commercial capacity for these technologies.

     Analysis of available commercial capacity (supply) and required capacity
(demand) showed shortfalls in available capacity for wastewater treatment and
incineration.  Consequently,  EPA  granted a two-year national capacity variance
to CERCLA and RCRA corrective action wastes;  small quantity generator (SQG)
wastes; and all wastes  containing less than 1 percent total F001-F005 solvent
constituents, i.e., solvent-water mixtures,  solvent-containing sludges,  and
solvent-contaminated soil (40 CFR 268.30 and the Background document for
solvents final rule).2

     EPA determined the volume of dioxin-containing waste generated annually
and affected by the restrictions.  Incineration capacity for these dioxin
wastes was  determined to be inadequate; therefore, a two-year national
capacity variance was granted (51 FR 40617).

     The final rule for the First Third Wastes, published on August 17,  1988
(53 FR 31138), included a reanalysis of available and required treat-
ment capacity for solvent wastes  using data from EPA's new data set based on
the results of EPA's National Survey of Hazardous Waste Treatment, Storage,
Disposal, and Recycling Facilities (the TSDR Survey).  The results of this

reanalysis demonstrated that adequate capacity exists  for solvent wastes    EPA
therefore allowed the capacity variances to expire on  November 8, 1988

1.2.2     California List

     Unlike the solvents and dioxins rule, the California list rule is not
waste code specific.  The California list includes all liquid hazardous waste
with a pH of less than or equal to 2.0 (i.e., acidic corrosive waste); all
liquid hazardous wastes containing free cyanide, metals, or polychlorinated
biphenyls (PCBs) in concentrations greater than or equal to those specified in
40 CFR 268.32; and all hazardous wastes (liquid or nonliquid) containing
halogenated organic compounds (HOCs) in amounts greater than or equal to the
levels specified in 40 CFR 268.32.

     The California list final rule was promulgated on July 8, 1987
(52 FR 25760).  This rule required the use of specific technologies rather
than the establishment of performance-based standards  for California list PCB
wastes and certain California list HOC wastes. 'Specifically, the rule
requires incineration in accordance with 40 CFR Part 264, Subpart 0, or Part
265, Subpart 0, for HOC wastes (except HOC wastewaters) and thermal treatment
in accordance with 40 CFR 761.60 or 761.70 for PCB wastes.  EPA codified the
statutory prohibition level (RCRA section 3004(d)(2))  for acidic corrosive
wastes (those with a pH of <2.0), but did not promulgate a treatment standard
for these wastes.  The final rule did not establish prohibition levels for
metal or cyanide wastes; therefore, upon promulgation, the RCRA section
3004(d)(2) statutory levels became effective.

     EPA originally used data from the 1981 RIA Mail Survey3 to determine the
maximum potential volume of land disposed waste subject to the California list
restrictions.  To determine the required alternative treatment capacity for
these waste volumes, EPA identified those technologies that it believed would
generally be used to treat California list wastes.  EPA then determined the
commercially available alternative treatment capacity  for these wastes.

-------
     A comparison of required and available treatment capacity for the
California list wastes for which a BDAT has been established showed that
incineration capacity for HOC wastes was inadequate.  Consequently, EPA
granted a two-year national capacity variance to HOC wastes requiring
incineration.  On the other hand,  EPA determined that adequate capacity for
PCS wastes did exist and thus did not grant a variance for these wastes.   EPA
believes that acidic corrosive,  cyanide, and metal wastes can be treated  to
below the California list statutory levels by tank treatment methods including
neutralization, cyanide oxidation, chromium reduction, and chemical
precipitation.  Furthermore, since the rule applies only to liquid wastes,
they may still be land disposed after being rendered non-liquid.
Consequently. EPA believed that adequate capacity for these wastes exists  and
did not grant a capacity variance for them.'1

     The final rule for the First Third wastes,  however,  included a reanalysis
of required  and available treatment capacity for California list HOC wastes
based on the TSDR Survey data.  The results indicated significant changes  in
waste management practices and capacity, specifically, substantial increases
in commercial incineration capacity.  As a result,  EPA determined that
capacity variances were no longer needed for HOC wastes,  except for
HOC-contaminated soils, and therefore rescinded the California list HOC
variance effective November 8, 1988.

1.2.3     First Third Wastes

     On August 17, 1988, the Agency published the final rule for the First
Third wastes.  This final rule promulgated treatment standards for some of the
First Third  wastes.  The remaining First Third wastes for which treatment
standards were not established were covered by the soft hammer requirements.

     EPA used the TSDR Survey data set to determine affected waste volumes
requiring alternative capacity and available commercial treatment/recovery
capacity   Required alternative capacity was then compared with available

commercial treatment/recovery  capacity.   This  comparison showed adequate
capacity for all  First Third wastes  except  petroleum refining wastes  (K048,
K049, K050, K051, and K052) for  which BOAT  is  sludge incineration or  solvent
extraction; high  zinc (greater than  or equal to  15  percent  zinc)  electric  arc
furnace dust (K061)  for which  BOAT is high  temperature  metals recovery; and
mercury cell chlorine production waste (K071)  for which BOAT  is acid  leaching.
Consequently, EPA granted  a two-year national  capacity  variance to  K048-K052
and K071 wastes.  EPA also granted a two-year  national  variance from  the high
temperature metals recovery-based standards to high zinc K061 wastes, but  in
the interim required these wastes to meet the  standard  for  low zinc K061 based
on stabilization.5

1.2.4     Underground Injected Wastes

     EPA has promulgated three final rules restricting  the underground
injection of certain wastes.   The first of these rules,  published on July 26,
1988 (53 FR 28118),  restricted solvent and dioxin wastes.  For  this final
rule, EPA used the results of  the TSDR Survey  to perform an analysis of
required and available treatment/recovery capacity.  The  results of the
analysis showed inadequate capacity  for the volume  of underground injected
solvent wastes containing  less than  1 percent  total  F001-F005  solvent
constituents for  which the BOAT  standard  is based on wastewater treatment
(steam stripping, biological treatment, wet-air oxidation, or carbon
adsorption)   Consequently, EPA  granted a two-year  national capacity variance
from the treatment standard until August  8,  1990, to underground injected
solvent wastes containing  less than  1 percent  total  F001-F005 solvent
constituents that are disposed of by injection in Class  I wells.

     Conversely,  the analysis  also showed that adequate  capacity did exist for
 he volume of solvent wastes containing greater than or  equal  to 1 percent
total' F001-F005 solvent constituents  for  which the  BDAT  standard is based on
incineration.   Consequently,  these wastes were restricted from underground
injection on August  8,  1988.    Furthermore, available data showed that no

-------
dioxin wastes are being injected,  and thus the Agency did not grant a variance
from the August 8,  1988,  effective date for restricting the underground
injection of these wastes.

     The second final rule  (53 FR 30908)  restricted the underground injection
of California list wastes and certain First Third wastes, specifically K062,
K049-K052, K071,  and K104.   For this rule, the Agency used data from the
Hazardous Waste Injection Well Data Base  (HWIWDB) and the TSDR Survey to
perform a capacity analysis for these wastes.   This analysis showed inadequate
capacity for all underground injected California list wastes except for those
containing greater than 50  ppm polychlorinated biphenyls (PCB) requiring
thermal treatment and wastes containing HOCs greater than 1,000 ppm requiring
incineration or reuse as fuel.  Furthermore, the analysis identified
insufficient capacity for all the First Third wastes subject to the rulemaking
(K062, K049-K052, K071, and K104).   EPA granted a two-year national capacity
variance to underground injected California list wastes (except PCB wastes
greater than 50 ppm and HOC wastes greater than 1,000 ppm) and K049-K052,
K062, K071, and K104 wastes.

     EPA published its approach for the remainder of the underground
injected First Third wastes on June 14, 1989 (54 FR 25416).

     EPA established effective dates for those underground injected First
Third wastes for which BOAT has been established but were not addressed in the
August 16, 1988,  final rule for underground injection wastes discussed
previously   EPA determined that sufficient capacity exists for K019 and K030
wastes for which BOAT is biological degradation, and for concentrated K016
wastes (>1 percent) and K103 wastes for which BDAT is liquid incineration.
However, for dilute K016 (<1 percent) wastes for which BDAT is biological
treatment followed by wet-air oxidation,  EPA determined that sufficient
capacity does not exist.  Consequently, for K019, K030, K103, and concentrated
K016 (>1 percent) underground injected wastes, EPA did not grant a national
capacity variance.  For dilute K016 (<1 percent) underground injected wastes,
however, EPA did grant a national capacity variance until August 8, 1990.

-------
1.2.5     Second Third Wastes

     On June 23, 1989, EPA  finalized  treatment  standards  for  some of  the
Second Third wastes,  for  some  of  the  First  Third wastes previously subject  to
the soft hammer provisions,  and also  for  some of the wastes that were
originally Third Third wastes.

     For the Second Third final rule  (54  FR 26594), EPA used  the TSDR Survey
to estimate the volume of affected wastes requiring alternative capacity and
the amount of available commercial capacity.  The results of  this analysis
showed that adequate  commercial capacity  does exist for all Second Third
wastes currently surface  disposed (i.e.,  treatment or storage in waste piles;
treatment, storage, or disposal in surface  impoundments;  and  disposal by land
treatment and in landfills).   However,  in order to allow  time for facilities
to adjust existing cyanide  treatment  processes  to operate more efficiently,
EPA decided to grant  a 30-day  extension for F006 nonwastewaters and for F007 ,
F008, F009, F011, and F012  wastes (both wastewaters and nonwastewaters).

     In addition, because F011 and F012 heat treating wastes  are often
commingled with F006, F007,  F008, and F009  electroplating wastes, EPA expects
that they will have to be segregated  and  treated separately.  To allow some
time to adjust processes  to segregate these heat treating (F011, F012) and
electroplating wastes (F006, F007, F008,  and F009), EPA deferred the total and
amenable cyanide standards  for F011 and F012 heat treating wastes until
December 8, 1989.  However,  between July  8,  1989, and December 8, 1989,  these
wastes will be subject to the  same cyanide  standards as the electroplating
wastes (F006, F007, F008, and  F009).

     The analysis also showed  that inadequate commercial  capacity existed for
the volume of underground injected wastes requiring liquid incineration or
reuse as fuel, cyanide destruction, and wastewater treatment  for organics.
Consequently, EPA granted a two-year  national capacity variance to underground
injected K011, K013,  and  K014  nonwastewaters, for which BOAT  is incineration;
to underground injected K009 wastewaters, for which BOAT  is steam stripping
                                      1-9

-------
and/or biological treatment; and to underground injected F007 wastes,  for
which BOAT is cyanide destruction.6

     In addition, as previously mentioned, EPA granted a thirty day variance
from the cyanide standards to F006 nonwastewaters and F007, F008, and  F009
wastewaters and nonwastewaters.  EPA deferred the cyanide standards for  F011
and F012 until December 8, 1989.  However, between July 8, 1989, and December
8, 1989, F011 and F012 wastes will be subject to the same cyanide standards as
the electroplating wastes (F006, F007,  F008, and F009).

1.3  Introduction to the Third Third Final Rule

     Today the Agency is promulgating treatment standards for a major  part of
the Third Third wastes as well as for First Third wastes and Second Third
wastes which were previously under soft hammer restrictions.   These wastes
include contaminated soils and some California list HOCs.   In addition to the
three Thirds, this final rule also accounts for multi-source leachate  and
mixed radioactive wastes.  These wastes, hereafter referred to as Third  Third
promulgated wastes are listed in Table 1-1 along with their designation  of the
Third group in which each individual waste was originally scheduled.

1.3.1  Surface-Disposed Wastes

     In the case of non-soil wastes, the analysis determined that available
capacity is less than required capacity for some surface-disposed wastes and
underground injected wastes.  Five treatment technologies fail to meet the
capacity requirements of surface disposed non-soil wastes:  acid leaching
followed by chemical precipitation; combustion of sludge/solids; mercury
retorting; thermal recovery; and vitrification.  Consequently, EPA is  granting
a national capacity variance for the following surface-disposed wastes:  D009,
K106, P065, P092, and U151  low mercury nonwastewaters; F039 raulti-source
leachate nonwastewaters  and K048, K049, K050, K051, and K052 nonwastewaters;
D009, K106, P065, P092,  and U151 high mercury nonwastewaters; D008 lead  acid

nonwastewaters; and D004, K031, K084, K101, K102,  P010, P011, P012, P036,
P038, and U136 nonwastewaters.  EPA is granting  these wastes a two-year
national capacity variance, except for K048, K049, K050, K051, and K052
petroleum-refining nonwastewaters.  EPA  is  granting K048-K052 petroleum-
refining nonwastewaters a six-month national capacity variance.

1.3.2  Deepwell-Disposed Wastes

     Nine commercial technologies also have less than the required capacities
for underground injected wastes.  EPA is granting  a two-year national capacity
variance for the following wastes:  D003 cyanide wastewaters and
nonwastewaters; D003 sulfide wastewaters and nonwastewaters; D003
explosive/reactive wastewaters and nonwastewaters; D007 wastewaters and
nonwastewaters; D009 nonwastewaters; D002 wastewaters and nonwastewaters; K011
and K013 wastewaters and K014 wastewaters and  nonwastewaters; and F039 multi
source leachate wastewaters.

1.3.3  Soil and Debris

     In the case of contaminated soils,  the capacities of four treatment
technologies did not meet the capacity needs of  the waste volumes requiring
treatment.  EPA is promulgating today an extension of the effective date for
certain First, Second, and Third Third contaminated soil and debris for which
the  treatment  standards promulgated today are  based on incineration, inorganic
solids debris  treatment, mercury retorting, or vitrification.

1.3.4  Mixed Radioactive Wastes

     In the analysis of mixed radioactive wastes,  EPA determined that there is
currently a treatment capacity shortfall for all mixed radioactive wastes that
are  surface-disposed.  Consequently, EPA is granting a two-year national
capacity variance for all surface-disposed  mixed radioactive wastes.  EPA has
no information on the deepwell-disposal  of  mixed radioactive wastes and,
therefore, is  not granting a national capacity variance for  these wastes.

                         2.  CAPACITY ANALYSES RESULTS

     This section presents  general  discussions  of  the  source(s) of data and
the methodology used for  the  capacity  analyses  in  support  of  the  final Third
Third rule.  Also presented are  the results  of  the  analyses of required and
available capacity conducted  for this  rule,  as  well as  for previous land
disposal restrictions.

2.1  General Methodology

     To evaluate the adequacy of alternative treatment  capacity for specific
waste categories, EPA  first puts restricted  wastes  into  "treatability groups"
that require similar treatment or management practices;  for instance, all
wastes requiring sludge incineration would be placed in  the same  treatability
group.  Where wastes present  particular  problems in treatment, EPA may
identify "treatment trains" of multiple  technologies operating in sequence.
Volumes of wastes in each treatability group are adjusted  3  reflect the
November 1988 deadline regarding minimum technology requirements  for surface
impoundments.  The net total  volume of currently land disposed hazardous waste
requiring alternative  treatment  capacity becomes the required capacity for
that treatability group.   EPA then  assigns the  volumes of  waste in each
treatability group to  treatment  technologies or treatment  trains.

     Determinations of available capacity take  several  factors into account,
some treatment processes  will generate various  treatment residuals, which then
have to be assigned to, and accounted  for within,  other  treatability groups.
Available capacity--the difference  between currently utilized capacity and the
total capacity of the  treatment  system--must take  into  account the commercial
status of each facility managing waste within a treatability  group:
     •    Available  treatment  capacity at  onsite  facilities used exclusively
          by  the waste  generator  cannot be considered  available to other
          generators .
     •    All  commercially available  capacity at  commercial facilities  is
          considered fully available  to any generator
                                      2-1

-------
     Capacity analysis  begins at the facility level and aggregates upward
toward the national level,  assigning available excess 'capacity by observing
the above rules.   For example,  available capacity at private treatment systems
applies only to wastes  currently land disposed at the same site.  Remaining
wastes are assigned to  commercial capacity.

     Each regulation within the Land Disposal Restriction Program accounts for
the sequential and cumulative effects of all previous regulations and for
projected capacity changes  after 1986,  as reported in the TSDR Survey.
Solvents and dioxins were considered first,  followed by California list
wastes, First Third promulgated wastes,  Second Third promulgated wastes, and
Third Third promulgated wastes.  Available capacity has been assigned first to
all affected surface-disposed wastes, (including surface-disposed multisource
leachate and residuals  from their treatment), then to all underground injected
wastes (including underground injected multisource leachates and residuals
from their treatment),  and finally to soil and debris wastes.  EPA sets this
priority because it believes that land disposal in surface units may represent
a greater threat to human health and the environment than does underground
injection.  Mixed radioactive wastes are considered separately because only
select facilities handle this type of waste.

2.1.1     Data Set Development
     (1)  National Survey of Hazardous Waste Treatment. Storage. Disposal, and
          Recycling Facilities

          (a)  Background.   To improve the quality of data used for capacity
analyses of hazardous waste volumes and management practices in support of the
land disposal restrictions, EPA conducted the National Survey of Hazardous
Waste Treatment, Storage, Disposal, and Recycling Facilities (the TSDR
Survey).  The TSDR Survey was designed as a census of RCRA-permitted or
interim status treatment, disposal, and recycling facilities, with no
weighting factors for statistical extrapolations to project national
estimates.  The survey also included a sample of storage-only facilities.  The
survey results thus provide a comprehensive source of data on waste volumes
land disposed and treatment, recovery, and disposal capacity.
                                      2-2

-------
     Receipt of the completed  surveys was  followed by extensive  technical
review and detailed analysis of  the  facility responses,  including facility
contact when necessary.  Certain facility  responses and  data elements derived
from the facility-level analysis were then incorporated  into a specialized
capacity data base  (a  series of  data sets) developed on  land disposal
facilities and commercial  treatment  and recovery facilities.  (See Section 4
for a detailed discussion  of the capacity  data base.)

          (b)  Schedule and status.  The TSDR Survey was originally mailed to
over 2,400 facilities  in August  1987.  Facilities were allowed 60 days to
complete and return the surveys.   Since August 1987, an  additional 225
facilities that either were initially overlooked or are  new have been
identified and sent the TSDR Survey.  Over 2,500 facilities had returned their
surveys by the deadline for review and analysis of data  to support this final
rule .

     A total of 475 facilities reported onsite land disposal/land placement
(surface disposal and  underground injection) of 63 billion gallons of RCRA
hazardous wastes during 1986,  the baseline year for the  survey.   All data were
reviewed and have been included  in the data set used to  support this final
rule.

     A total of 236 facilities with  commercial treatment/recovery technologies
in 1988 have completed and returned  surveys, accounting  for a maximum of 11.4
billion gallons per year of commercial hazardous waste alternative capacity in
1988.  Some of these facilities  also reported land disposal onsite and are
included among the 475 facilities noted above.

     One hundred and ninety-five facilities reported having commercial
processes in 1988 other than combustion, mostly wastewater treatment capacity.
that may be applicable as  alternative treatment/recovery of Third Third
promulgated wastes, accounting for a maximum capacity of 8.7 billion gallons
of commercial noncombustion treatment/recovery capacity  in 1988.

     Sixty facilities  reported commercial  combustion processes (incineration
or reuse as fuel) that may be  applicable for burning hazardous waste currently
being land disposed, accounting  for  a maximum capacity of 499 million gallons
                                      2-3

of commercial liquid combustion capacity and 68 million gallons of commercial

sludge and solid combustion capacity in 1988.


     A total of 15 commercial treatment/recovery facilities have not returned

their surveys to date.  To fill known data gaps, these late facilities were
contacted to gather critical capacity information;  where available, other data

sources were also used.


          (c)  Technology capacity information.  The TSDR Survey was designed

to provide comprehensive information on all current and planned hazardous
waste treatment, disposal, and recycling processes  at all RCRA-permitted and
interim status facilities, including information on exempt processes at these

facilities (e.g., recycling, wastewater treatment).1  The  baseline  year for
the survey was 1986.  Information was requested on  any planned changes to
existing processes, including closures, and any new processes planned prior to

1992.


     The survey included the following information  on treatment and recycling
processes, including those taking place in land placement units:
     •    General categories
          (including new or planned
           processes)
     •    Key parameters
     •    Waste types

Planned changes through 1992
       Exceptions  include  totally enclosed  treatment  facilities  (TETFs)  and
closed loop recycling (CLR),  which were  not required to be reported.  Also, the
TSDR Survey did  not  gather  information on facilities having  exempt processes
only.

          (d)  Waste volumes  land disposed.  The TSDR Survey was also designed
to provide information on  the  types and quantities of all RCRA hazardous waste
managed, by specific land  disposal/placement practices, at all RCRA-permitted
and interim status facilities.  The survey provides  limited but adequate
characterization data (refer  to Subsection 4.1.2, Treatability Analysis) to
assess the treatability potential of  the wastes and  to identify applicable
alternative treatment/recovery technologies, including:

     •    RCRA waste code  (or  codes,  if more than one is applicable);
     •    Waste description  (physical/chemical form  and qualitative
          information on hazardous characteristics and constituents);
     •    Industry description (general description  of the industries that
          generated each type  of waste at a facility);
     •    Quantity that entered land  disposal/placement in 1986; and
     •    Residual information (whether this waste was actually a residual
          from onsite hazardous waste management operations).

     The TSDR Survey also  provides valuable detailed information on  the
individual units in which  land disposal/placement is occurring, including
plans for closures and upgrading/retrofitting to meet the minimum technology
requirements.  Through review  of the  questionnaire responses and the facility
schematics,  it is possible to  track individual waste streams managed in more

           (e)  Overview of data handling, technical review, and quality

assurance.  Extensive technical review of TSDR Survey data was required to

ensure completeness, consistency, and accuracy on a per-facility basis.  To

achieve this goal,  the review process was designed to promote the consistent

and efficient  identification and resolution of any errors, inconsistencies,

and omissions, including any required facility follow-up.  The review

procedures were  comprehensive and required the consideration and analysis of

the facility responses to essentially every question in the survey (if

applicable to  that  facility) , as well as the review of general and detailed

schematics of  all onsite hazardous waste management operations.  The detailed

review procedures are presented  in  the  report Technical Review Procedures  for
the TSDR Survey.*

     All surveys from TSDR  facilities with  onsite  land disposal/placement
(whether private or commercial)  or  commercial treatment/recovery operations
were considered critical  for  support of the  land disposal restrictions.
Therefore, they were categorized as "priority" surveys and were given
immediate technical review  and analysis,  including facility contact to resolve
any major technical problems  discovered in  their responses.  The required  data
entry forms were completed  for either land  disposal/placement and/or
commercial treatment/recovery, and  the  survey package underwent a preliminary
quality control (QC) -review by the  technical supervisors.  As part of this
preliminary QC, the supervisor then worked with the reviewer to correct or
resolve any problems identified  during  the  survey review.  Every survey
underwent preliminary QC  review.  (See  Technical Review Procedures for the
TSDR survey for details on  the survey screening, distribution, and review
procedures . )5

     Treatability assessments of each land disposed waste stream were then
conducted, as described in  Subsection 4.1.2, Treatability Analysis to identify
potentially applicable alternative  technologies.

     The last step in the review process  involved a detailed,  or final,  QC on
approximately 25 percent  of the  surveys.  (See Quality Assurance Plan for the
TSDR survey for detailed  information on QC procedures.)6   After  QC,  the
technical review/analysis was considered  to be complete.

on wastes land disposed at the site to include in the capacity analysis.   The
facility indicated that records of 1986 were not available which could supply
the detailed information.

     EPA requested additional information and CWM-Emelle responded by
providing data from their 1987 Alabama Department of Environmental Management
Facility Hazardous Waste Biennial Report and other statistical information on
management of hazardous waste at the facility.  These data were included in
the TSDR Survey data base, and have been used to revise capacity analysis  for
the prior rules and to prepare the capacity analysis for this final rule.

     These data provide information on waste streams managed at the site in
1987, not 1986 as in the TSDR Survey.   It is considered, however,  to be the
best information available from the facility to estimate the required
capacity   The data describe over 3,000 waste streams received or generated at
the facility, including a brief description of the waste,  the handling method,
the applicable RCRA waste code(s),  and the volume of the waste received or
generated.

     The handling method represents the disposition of the waste stream as of
the end of 1987.  The handling method in over 99 percent of the waste streams
received and/or generated was disposed in landfills.   These waste  streams
require alternative treatment.  Other handling methods specified were for
storage and thermal treatment.  Because these are not land placement methods,
these waste streams did not require alternative treatment.

     The data for each waste stream were evaluated and a waste description
code was assigned to each waste stream reported to be landfilled.   The main
source of information used to assign waste description codes was the
description of the waste stream and the RCRA waste codes.   A detailed
discussion of this procedure may be found in Section 4.1.   Treatability
assessments of each landfilled waste stream were then conducted,  as described
in Subsection 4.1.2, to identify potentially applicable alternative
technologies.

     (2)  National Survey  of  Hazardous  Waste  Generators
          (a)  Background.  The  primary purposes  of  the Generator Survey were
(1) to gather waste characterization data  on  hazardous waste streams generated
in the United States and  (2)  to  gather  information about exempt treatment and
recovery processes at  generation facilities used  to  manage these wastes.  Late
in 1987, Generator Surveys were  sent to approximately 10,000 hazardous waste
generator facilities.   Over 300  additional facilities were sent Generator
Surveys in a second mailing of surveys  in  early 1988.  These facilities were
considered representative  of  the hazardous waste  generators in their States
(based on the 1985 Biennial Report  data).  They included all facilities that
were sent a TSDR  Survey as well  as  the  largest  (non-TSDR) hazardous waste
generators in each State,  including the 1,000 largest generators in the U.S

          (b) Schedule and status.   The Generator Survey consisted of nine
questionnaires  (Questionnaires GA through  GI).  Questionnaire GA requested
general facility  information  and information  about waste minimization
practices, hydrogeology,  and  solid  waste management  units (SWMUs).
Questionnaire GB  requested waste characterization and minimization data for
each hazardous waste stream generated at a facility, and Questionnaire GI
requested information  on  tanks used to  manage hazardous waste.   The remaining
questionnaires asked for  information about specific  exempt treatment and
recovery operations.   As  with the TSDR  Survey, historical data for calendar
year 1986 activities and  estimated  data for planned  (treatment and recovery)
activities through 1992 were  requested.

          (c)  Uses.   For  this final rule, data from the Generator Survey were
used for two primary purposes (a report containing the Generator Survey data
used to support this rule  is  contained  in  the public docket).7   First,  EPA
used Generator Survey  data to authenticate some larger volume wastes reported
as land disposed.  EPA used the  Generator  Survey  data to compare the amount
generated vs. the amount  reported as being land disposed in the TSDR Survey
The Generator Survey data  were also used to determine if unusual mixtures
reported as being land disposed  in  the  TSDR Survey were generated as mixtures

     (3)   Multi-Source Leachate Data Sources
          EPA used two primary data sources to perform the capacity analysis
for multi-source leachate:   The TSDR Survey and the Generator Survey.  EPA
analyzed data on the volumes of multi-source leachate generated and managed,
including data on the facility schematics.   In addition to data included  in
the surveys, EPA used additional data from the hazardous waste management
industry submitted as part of the leachate study plan (Appendix A describes
these data sources in further detail).

     (4)  Mixed Radioactive Waste Data Sources
          Mixed radioactive waste data sources included data provided by the
Department of Energy (DOE), the TSDR Survey, Generator Survey, surveys and
reports for states and interstate compacts, published studies of mixed
radioactive wastes, and phone contacts with government representatives and
industry officials.  Attachment B-l of Appendix B describes these data sources
in more detail.  The DOE data provided information on mixed radioactive wastes
at 21 DOE facilities.  Data on each waste included annual generation rates and
quantities of mixed radioactive wastes in storage.  Also included is
information on DOE teatment units at each facility,  including treatment
capacity and types of wastes handled.

     The quantities of mixed radioactive wastes generated at DOE facilities
were determined to constitute a large portion of all mixed radioactive wastes
generated, based on an analysis of the DOE data set and the non-DOE mixed
radioactive waste  information.  Consequently, the capacity analysis focused
primarily on the data provided by DOE.

     (5)  Other Data Sources
          Additional data sources were used when necessary to fill data gaps.
One such data source was the EPA Office of Drinking Water's (ODW's) Hazardous
Waste Injection Well Data Base (HWIWDB) .   The HWIWDB was used to estimate the
volume of some underground injected wastes for which the TSDR Survey did not
have data.8  Other data were obtained from published literature  (as. described
in Subsection 4.1.2).

-------
     For some critical  elements  of the  capacity  analysis,  EPA  updated  the TSDR
Survey data.  The  amount  of sludge/solid combustion  capacity was  one such
update.  In the TSDR  Survey,  facilities were  asked to  provide  data  on  planned
hazardous waste treatment systems,  including  combustion  systems.  Using data
obtained from EPA  headquarters and regional personnel  and  from facility
contacts, EPA determined  which units  were now on-line, which were experiencing
delays, which were not  going to  be built, etc.   In addition, using  data
obtained from facility  contacts,  EPA  updated  data on certain P and  U-coded
waste streams reported  in the TSDR Survey as  being land  disposed  in large
volumes.  EPA gathered  data on the current volume, physical/chemical
characteristics, generating source(s),  and management  of these  wastes.   These
updated data were  used  to adjust the  capacity analyses for these wastes

2.1.2     Capacity Analysis Methodology

     This section  presents a brief description of EPA's  capacity analysis
methodology.  A detailed  explanation  of the methodology  is contained in
Section 4.

     EPA assesses  capacity requirements by comparing "required" capacity with
"available" capacity.   The following  sections briefly  describe how required
and available capacities  were determined.

     (1)  Required Capacity
          Required capacity,  or  capacity demand, consists of those volumes of
wastes currently land disposed that will require alternative treatment or
recovery when they are  restricted from  land disposal,  and also  includes the
residuals generated by  treatment of these wastes.  The waste streams
potentially affected  by the land disposal restrictions were identified by type
of land disposal,  including treatment,  storage,  or disposal in  a surface
impoundment; treatment  or storage in  a  waste  pile; disposal by  land treatment;
and disposal in a  landfill or an underground  injection well.  Unlike the
previous land disposal  restrictions in  which  underground injected wastes were
considered under a separate rule, both  surface disposed  and underground
injected wastes are included in  the Second Third and Third Third Final rules.
                                      2-11

-------
     Salt dome formations, salt bed formations, and underground mines  and
caves are additional methods of land disposal that are affected by  this
rulemaking.  Since insufficient information is available to document the
volume of wastes disposed of by these three methods, they are not addressed  in
the analysis of volumes and required alternative capacity.

     The volumes of waste reported in the TSDR Survey as land disposed in  1986
that require alternative treatment/recovery capacity were adjusted  to reflect
the fact that treatment in surface impoundments after November 1988 may be
conducted only in impoundments meeting minimum technological requirements.
Volumes of waste that were reported as undergoing treatment in impoundments
meeting these requirements in 1988, or in impoundments being replaced by tank
systems by 1988, were dropped from further analysis.  Residuals from the
treatment of these wastes in minimum technology impoundments or tanks were
assumed to require further treatment prior to land disposal and therefore are
included in the capacity analysis for this final rule.   The waste volumes
requiring alternative capacity were identified by RCRA waste code(s) and by
their land disposal ban regulatory status (i.e., solvents and dioxins,  First
Third, Second Third, Third Third, and California list).   A detailed discussion
of this methodology is presented in Subsection 4.1.1.

     To determine the type of alternative capacity required by the affected
wastes, a "treatability analysis" was performed on each waste stream.   Wastes
were placed into "treatability groups" using the waste code, the physical/
chemical form data, and information on prior management and the type of land
disposal, and then considering the identified BDAT technologies.   For example,
all wastes requiring liquid incineration would be placed in the same
treatability group.  The physical/chemical form data were provided by the
facility using qualitative technical criteria, not regulatory definitions.
For example, liquid wastes were identified as "highly fluid" rather than as
"wastes failing the Paint Filter Liquids Test."

     Waste groups (i.e., waste streams described by more than one waste code)
present special treatability concerns because they often contain constituents
requiring different types of treatment (e.g., organics and metals).  To treat
these wastes, a treatment train must be developed that can treat all waste
types in the group.  A more detailed description of the treatability analysis
                                     2-12

-------
methodology, including  treatment  train development,  is presented  in
Subsection 4.1.2.

     A number of the  treatment  technologies  to which wastes have  been assigned
create treatment residuals  that will  require further treatment prior to land
disposal (e.g., stabilization of  incinerator ash)    In these
cases, EPA has estimated  the amount of residuals  that would be generated by
treatment of the original volume  of waste and has  included these  residuals in
the volumes requiring treatment capacity.  A more  detailed description of the
determination of residual volumes is  presented
in Subsection 4.1.2(4).

     For a number  of  wastes, BDAT includes treatment of incinerator scrubber
water.  Based on TSDR Survey responses,  the RCRA-permitted incinerators have
adequate air pollution  control  devices (APCDs) (including scrubber water
treatment at those facilities with wet scrubbers), and therefore no additional
analysis of the volume  of scrubber water was made.  However, if the resultant
scrubber water treatment  sludge would likely require further treatment (e.g.,
stabilization) , these residuals were  included in  the volumes requiring
treatment capacity.

      (2)  Available Capacity
          To obtain estimates of  available capacity  that could be compared
with  the capacity  requirements  of affected wastes, a "systems" approach was
taken.  A system is defined as  one or more different processes used together
in one or more different  units  to treat  or recover hazardous waste.  The
capacity of the treatment/recovery system may be  limited by the capacity of
one or more of the unit processes within the system.  The available capacity
of the system  is determined by  subtracting the utilized capacity  of the system
from  the maximum capacity of the  system.  A  detailed discussion of system
capacity determination  can  be found in Subsection 4.2.2.

      Comparing required capacity  with available capacity begins at the
facility level and moves  to the national level, as dictated by the available
capacity and commercial status  of applicable treatment/recovery systems.  The
available capacity of systems identified as private  is considered only when  it
is BDAT, and only  for the wastes  reported as being land disposed  at that
                                      2-13

-------
facility   Waste volumes assigned to onsite BDAT technologies are not
considered in the national totals of required commercial capacity.

     The remaining volumes of waste still requiring treatment capacity are
added to determine the national demand for commercial capacity of each
alternative technology   Consequently, all estimates of capacity presented
in this document represent commercially available (not private) capacity.

     By comparing the required capacity with the available commercial
capacity, EPA can identify capacity shortfalls and make determinations
concerning variances.  The comparative capacity analysis accounts for the
sequential and cumulative effects of previous land disposal restrictions,
capacity variances, and projected capacity changes after 1986 (the baseline
year).  Solvents and dioxin wastes were assigned to available capacity first,
followed by California list HOCs (other than those that are also First Third
or Third Third promulgated wastes),  First Third promulgated wastes,  Second
Third promulgated wastes, and finally Third Third promulgated wastes.  In
addition, available capacity was first assigned to all affected wastes land
disposed in "surface" units (i.e., waste piles,  surface impoundments,
landfills, and land treatment), and then to underground injected wastes.   EPA
believes that land disposal in surface units may represent a greater threat to
human health and the environment than does the underground injection of
wastes.

2.2  Results

     The following subsections present the results of the capacity analyses
conducted for this final rulemaking and previous rulemakings.   All land
disposed hazardous wastes, including those capable of being treated onsite in
BDAT systems and wastes stored only in land disposal units, are included in
the overview tables.  As mentioned earlier, land disposed wastes capable of
being treated onsite in a BDAT system have not been included in the national
estimates of required capacity; therefore, only commercially available
capacity is presented in this document.  In addition,  the amount of commercial
capacity available for each rulemaking always considers the amount used by
previous rulemakings.

2.2.1     All RCRA Wastes

     Table 2-1 presents estimates of the volumes of RCRA wastes  that  are
surface land disposed annually.  These volumes were compiled by  adding all
waste stream volumes managed by treatment, storage, or disposal  in surface
land disposal units.  Separate waste volumes are shown for storage and
treatment in waste piles; treatment, storage, and disposal in surface
impoundments; and disposal in landfills and land treatment units.  The
baseline data for determining the volumes in Table 2-1 were the  1986  data from
responses to the TSDR Survey.  These reported 1986 volumes were  adjusted by
subtracting the volumes of waste managed in treatment surface impoundments
that have undergone closure and have been replaced by tanks or that have been
retrofitted to meet minimum technology requirements. (Data reported in tons
were converted to gallons (using the conversion factor of 240 gallons/ton,
based on the density of water), to allow comparisons to available capacity in
a standard unit).

     To avoid double-counting of wastes that underwent more than one
management operation in the same type of unit (e.g., storage and treatment in
a waste pile) , the following procedures were used:

     •    In tabulating volumes of waste managed in surface
          impoundments and waste piles, any wastes that underwent
          treatment in an impoundment or waste pile were reported in
          the "treatment" volume.
     •    Wastes stored in a surface impoundment or waste pile that
          never underwent treatment in the impoundment or waste pile
          were reported in the "storage only" volumes.
     •    In tabulating surface impoundment volumes, wastes that
          were disposed of in surface impoundments but not also
          treated in the impoundment were included among "disposal"
          surface impoundment volumes.

     Not represented in the estimates in Table 2-1 are volumes of surface land
disposed waste from facilities that did not return their TSDR Surveys before
April 1989 or did not provide sufficient data on land disposal.  Based on the
limited information provided by these facilities, EPA estimates  that  these
facilities accounted for approximately 8 million gallons of land disposed
waste in 1986.  This represents less than 1 percent of the reported 1988

adjusted volume of surface  land  disposed hazardous  waste.   Sufficient  data
were not available to determine  specific management practices  and RCRA waste
codes associated with these volumes.

2.2.2     Solvents

     For the First Third  final rule  promulgated August  8,  1988, EPA performed
a reanalysis of required  and  available  treatment capacity  for  surface  land
disposed solvent wastes.9   This  subsection summarizes the results of that
analysis.  The capacity analysis for underground injected wastes was performed
for a separate rulemaking.

     Table 2-2 presents estimates of the volume of  solvents  that are surface
land disposed annually, by  management practice  and  by type  of  land
disposal unit.  The  same  procedures  described for the analysis of all  RCRA
wastes were used for estimating  solvent volumes.  The entire volume of any
waste stream, for both single waste  streams  and waste groups (waste described
by more  than one waste code), was considered if the waste stream
contained any solvent wastes.

     The volume of surface  land  disposed solvent wastes requiring alternative
commercial treatment capacity is less than the  volume of solvents land
disposed.  This is because  EPA has assumed that the 13 million gallons of
solvent  wastes that  were  only stored in impoundments or waste piles do not
require  alternative  treatment capacity  (although they may require alternative
storage  capacity) because they are treated or disposed of elsewhere.
Furthermore, the facility-level  waste treatability  and technology capacity
analyses conducted on solvent wastes being land disposed determined that 34
million  gallons of these  wastes  either  had already  been treated using  the BOAT
technology or could  be treated onsite,  and therefore were not  included in the
volumes  requiring alternative commercial treatment/recovery  capacity.  Based
on this, EPA estimates that 52 million  gallons  of solvent wastes will  require
alternative treatment/recovery capacity on a commercial basis.  This volume

includes 25 million  gallons  of  soil; therefore,  it  is  estimated  that  only
27 million gallons of nonsoil solvent wastes will require alternative
commercial treatment capacity.10  Finally,  EPA estimates that treatment of
this 27 million gallons will generate 4 million  gallons of waste residuals
that will also require additional alternative  treatment capacity

     Table 2-3 presents the  estimates of available  commercial capacity for the
alternative technologies that are applicable to  solvent wastes.  Also
presented are the estimates  of  annual surface  land  disposed waste volumes that
require alternative  commercial  capacity based  on the facility-level
treatability and capacity analyses  (not including contaminated soils or
underground injected wastes)    As evident from the  table, EPA determined that,
based on the new data available from results of  the TSDR Survey,  there was
adequate capacity for all of the solvent wastes  that will require alternative
capacity.u

2.2.3     Nonsolvent RCRA Wastes Containing Halogenated Organic Compounds
          (HOCs)

     For the First Third final  rule, EPA performed a reanalysis of required
and available treatment capacity for California  list HOCs.12  This subsection
summarizes the results of that  analysis.  The  capacity analysis for
underground injected wastes was performed for  a  separate rulemaking.

      Tables 2-4 through 2-6 present estimates of annual surface  land disposed
volumes for nonsolvent RCRA wastes  that are potential California  list wastes
containing HOCs at concentrations of 1,000 mg/kg or greater.   Separate tables
are presented for total HOC wastes, HOC wastes that are also First Third
     10  Note:    Originally  an  additional  16  million  gallons  of  solvent -
contaminated wastewater treatment sludge was deemed to require incineration.  The
sludge,   however,   results  from  the  treatment  of  multisource  leachate  and
consequently is evaluated under this  final  rule  and  is not  now subject to the
solvents rule.

promulgated wastes,  and all other HOC wastes.  The same procedures used  for
tabulating all RCRA wastes apply to HOC volumes.  However, the total volume
for each management practice in Tables 2-4 through 2-6 represents the  sum of
all single HOC waste streams (in that table's regulatory group) and all  waste
groups containing at least one potential HOC waste (in that table's regulatory
group) but containing no solvents.

     The volume of land disposed HOC wastes requiring alternative commercial
treatment capacity is less than the volume of HOC wastes land disposed.  This
is because the facility-level treatability and capacity analyses conducted on
the HOC wastes being land disposed determined that 3 million gallons of  these
wastes could be treated onsite and therefore were not included in the  volume
requiring alternative commercial treatment capacity.  Based on this, EPA
estimates that 18 million gallons of HOC wastes will require alternative
treatment capacity on a commercial basis.  This volume includes 6 million
gallons of soils  (2 of the 6 million gallons of HOC soils were assigned  to
onsite treatment); therefore, it is estimated that only 12 million gallons of
nonsoil HOC wastes will require alternative commercial treatment capacity.

      Table 2-7 presents the results of the facility-level treatability  and
capacity  analyses for non-Third Third promulgated HOC-containing wastes  (not
including underground injected waste volumes).  To eliminate double-counting,
this  table does not include wastes that contain First Third promulgated  wastes
or solvents.  In addition,  those HOC wastes that are also Third Third
promulgated wastes have been included in  the capacity analysis for Third Third
promulgated wastes and not here.

      Based on the data from the TSDR Survey, EPA determined that adequate
capacity  exists for the volume of HOC wastes requiring combustion.
Consequently,  EPA rescinded  the national  capacity variance previously  granted
 to these  wastes.13

2.2.4     First Third Wastes

     In support of the First Third final rule, EPA performed facility-level
treatability and capacity analyses on First Third waste streams.1'1   This
subsection documents the results of the capacity analysis for the First Third
wastes.  As previously mentioned, the First Third final rule did not include
underground injected wastes.

     (1)  All First Third Wastes

          Table 2-8 presents the estimates of all First Third wastes (as
listed in 40 CFR 268.10) that are surface land disposed annually, by
management practice and by  type of disposal unit.  The total volume for each
category in Table 2-8 represents the sum of all single First Third waste
streams and all waste groups containing at least one First Third waste but no
solvents.  This prevents double-counting of multiple waste streams that
contain both First Third wastes and solvents.
      (2)  First Third Wastes for which Formal Treatment Standards have been
          Promulgated
          Table  2-9 presents estimates of the annual volume of First Third
wastes surface land disposed for which treatment standards were promulgated,
by management practice and by type of disposal unit.  These wastes are
referred  to hereafter as First Third promulgated wastes.  The same procedures
described for the analysis of all RCRA wastes were used for estimating First
Third promulgated waste volumes.  The total volume for each category in Table
2-9 represents the sum of all single First Third promulgated waste streams and
all waste groups containing at least one First Third promulgated waste but no
solvents.  This  prevents double-counting of multiple waste streams that
contain First Third promulgated wastes and solvents.

a First Third promulgated wastes  are  those  wastes  for  which treatment
  standards were finalized on August 8,  1988.
                                     2-28

-------
     The volume of land disposed First  Third  promulgated wastes  requiring
alternative commercial treatment capacity  is  less  than  the volume  of  First
Third promulgated wastes  land disposed.  This is because EPA has assumed that
35 million gallons of the 45 million  gallons  that  were  only stored in
impoundments or waste piles do not  require  alternative  treatment capacity
because they are treated  or disposed  of elsewhere  (although they may  require
alternative storage capacity).  The 10  million gallons  of  "stored  only" wastes
that do require alternative capacity  were  determined  to have undergone
"long-term storage" and therefore would not have been reported elsewhere as
treated or disposed of.   Furthermore, the  facility-level waste treatability
and technology capacity analyses conducted  on First Third wastes being land
disposed determined that  341 million  gallons  of these wastes either had
already been treated or could be treated onsite using the BDAT technology and
therefore do not require  alternative  commercial treatment capacity    This
volume includes 290 million gallons of  wastewater  from  one facility assigned
to onsite dewatering in tanks.

     Table 2-10 presents  estimates  of available commercial capacity for the
alternative technologies  applicable to  the  First Third promulgated wastes.
Also presented are the estimates of annual  land disposed waste volumes
requiring alternative commercial capacity,  excluding  First Third promulgated
wastes that are underground injected  or soils contaminated with First Third
promulgated wastes which  were granted a two-year capacity variance.   In most
cases, adequate capacity  was available  to  treat all of  the First Third
promulgated wastes and mixed waste  groups  containing  a  First Third promulgated
waste.

     As Table 2-10 shows, four technologies had required capacity  exceeding
the available capacity:   acid leaching  of  sludges, high temperature metals
recovery, solvent extraction, and combustion  of sludges/solids.

     BDAT for K071 was identified as  acid  leaching of the sludge.  Because of
the shortfall of acid leaching capacity, EPA  granted  a  two-year national
capacity variance for K071 wastes.

     High temperature metals  recovery (HTMR)  was  identified  as  the BOAT  for
"high zinc" K061  (i.e., K061  containing  >15 percent  zinc).   Because  of the
shortfall of HTMR capacity, EPA  granted  a  two-year capacity  variance  to  the
HTMR standard for high  zinc K061.   However, during this  two-year variance
period, EPA is requiring  that high  zinc  K061  meet the  standard  for low zinc
K061, which is based on stabilization.   Therefore, 63  million gallons of K061
waste have been "double-counted"  on Table  2-10 under both stabilization and
HTMR.

     The required capacity  for the  combustion of sludges/solids was divided
into two numbers:   the  total  amount of waste  that requires sludge/solid
combustion, 162 million gallons,  and the amount of First Third promulgated
waste other than K048-K052  waste  that requires sludge/solid  combustion,
8 million gallons.  The BOAT  standard for  K048-K052 was also based on solvent
extraction, however, and  thus the required capacities  for these technologies
are presented as  ranges on  Table  2-10.   The total volume of  K048-K052 wastes
requiring capacity  has  been determined to  be  154 million gallons.
Consequently, because of  a  shortfall of  sludge/solid incineration and solvent
extraction capacity, EPA  granted a  two-year national capacity variance for
K048-K052 wastes.

     (3)  Soft Hammer Wastes  from the First Third Final Rule

          The First Third soft hammer wastes  for which treatment standards
were not promulgated in the First Third  final rule (i.e., "soft hammer"  First
Third wastes) include F006  wastewaters,  F019, K004, K008, K011 wastewaters,

from che First Third final rule were promulgated in the Second Third  final
rule.   Treatment standards for the remainder are being promulgated  in today's
final  rule.

2.2.5           Underground Injected Solvent Wastes

     On July 26, 1988 (53 FR 28118), EPA published the final rule regulating
underground injection of F001-F005 solvents and of F020-F023 and F026-F028
dioxin wastes.  The results of the capacity analysis for these wastes  are
presented in Table 2-11.

     EPA used the data resulting from the TSDR Survey to estimate the  amount
of required alternative commercial treatment capacity.   For this rule, EPA
estimated that 317 gallons of solvent wastes are underground injected
annually.  The TSDR Survey does not contain detailed data on the concentration
of contaminants in wastes; however, based on waste descriptions, EPA estimated
that at least 260 million gallons were solvent-water mixtures containing less
than 1 percent total F001-F005 solvent constituents at the point of
generation.  The appropriate treatment for these wastes was identified as
wastewater treatment for organics (steam stripping, carbon adsorption,
biological treatment, or wet-air oxidation).  Using the TSDR Survey, EPA
identified only 55 million gallons of available commercial wastewater
treatment for organics.  Consequently, EPA granted a national capacity
variance for solvent-water mixtures with less than 1 percent total F001-F005
solvent constituents until August 8, 1990.

     EPA estimated that the remaining 57 million gallons of underground
injected solvent wastes contained F001-F005 constituents in concentrations
greater than or equal to 1 percent at the point of generation.   The BOAT
standard for these wastes is based on the performance of liquid combustion.
Using the TSDR Survey, EPA identified 338 million gallons of available liquid
combustion capacity.  EPA, therefore, did not grant a national capacity
variance to those wastes.

     EPA determined that F020-F023 and F026-F028 dioxin wastes were not being
underground injected and that restricting them would have a negligible effect
on available treatment capacity; EPA, therefore, did not grant a two-year
capacity variance to these wastes.

2.2.6     Underground Injected California List Wastes

     On August 16, 1988, EPA published its regulatory approach for underground
injected California list wastes.  The results of the capacity analysis for
these wastes are shown on Table 2-12.  This subsection summarizes the capacity
determinations for each California list waste type.

     (1)  Free Cyanides
          For this rule, EPA determined that 1.36 billion gallons of cyanide
wastes are underground injected annually.  EPA estimated that at least 170
million gallons of this waste exceeded the statutory prohibition level of
1,000 mg/1.  Using the TSDR Survey, EPA identified only 16 million gallons of
available cyanide oxidation capacity.  Consequently,  EPA granted a national
capacity variance to underground injected California list cyanide wastes until
August 8, 1990.

     (2)  Metals
          EPA estimated that 234 million gallons of waste exceeding the
California list standards for metals (other than chromium) are underground
injected annually.  Using the TSDR Survey available at the time,  EPA
identified 128 million gallons of available commercial chemical precipitation
capacity.  Consequently, EPA granted a national capacity variance to
underground injected California list metal-bearing wastes until August 8,
1990.

     (3)  Chromium wastes

     EPA identified 105 million gallons of wastes with chromium levels
exceeding the California list limits.  EPA also identified an additional 237
million gallons of wastes that could potentially exceed the chromium levels.
Using the TSDR Survey, EPA determined that 79 million gallons of chromium

c At the time the California list rule went into effect,  the available
  capacity for chemical precipitation was determined to be  128 million
  gallons.  As a result, 234 million gallons of waste requiring chemical
  precipitation were granted a two-year national capacity variance.  Since
  promulgation of the California list rule, EPA has received additional
  information.  The  364 million gallons reported today is based on this
  additional information.
                                      2-35

-------
reduction, chemical precipitation, and settling or filtration capacity was
available to treat these wastes.  Thus, EPA decided to grant a national
capacity variance to underground injected California list chromium wastes
until August 8, 1990.

     (4)  Corrosives
          EPA identified over 1 billion gallons of underground injected acidic
corrosive (pH <2) wastes subject to the California list prohibitions.  Using
the TSDR Survey, EPA identified only about 36 million gallons of available
commercial neutralization capacity.  Consequently, EPA granted a national
capacity variance to underground injected California list corrosive wastes
until August 8, 1990.

     (5)  Halogenated Oreanic Compounds (HOCs)
          EPA divided California list HOC wastes into two subgroups:
concentrated HOC wastes containing greater than or equal to 10,000 mg/1 (1
percent) HOC constituents, and dilute wastewaters with HOC concentrations
between 1,000 and 10,000 mg/1.  In addition,  wastes that qualify as both HOCs
and First Third promulgated wastes were included with the First Third
promulgated wastes and not with the HOCs to avoid double counting.

     EPA determined that the volume of concentrated HOC wastes being
underground injected was substantially less than the amount of available
liquid combustion capacity (the specified BDAT for these wastes).   EPA,
therefore, did not grant a national capacity variance to underground injected
California list wastes with HOC concentrations greater than or equal to 10,000
mg/1.

     Using the TSDR Survey, EPA identified 245 million gallons of underground
injected dilute HOC wastewaters (HOCs between 1,000 and 10,000 mg/1).  EPA
identified only 55 million gallons of available wastewater treatment capacity
applicable to these wastes (steam stripping,  carbon adsorption, biological
treatment, or wet-air oxidation).   Consequently, EPA granted a national
capacity variance to underground injected dilute California list HOC
wastewaters until August 8, 1990.
                                     2-36

-------
     (6)  Polvchlorinated Biphenyls (PCBs)
          EPA identified 25,000 gallons of underground  injected PCBs; however,
EPA does not believe that these wastes exceed the statutory prohibition level
of 50 ppm.  Furthermore, data from both the TSDR Survey and the RIA Mail
Survey indicate that treatment capacity for these wastes  (liquid combustion)
substantially exceeds the volume injected.  EPA, therefore, did not grant a
national capacity variance to underground injected California list PCB wastes.

2.2.7     Underground Injected First Third Wastes

     EPA's regulatory approach for underground  injected First Third wastes was
outlined in two parts.  The first part, published on August 16, 1988 (53 FR
30908), covered underground injected K049-K052, K062, K071, and K104 wastes.
EPA's published regulations on the remaining underground  injected First Third
wastes were published on June 14, 1989 (54 FR 25416).   Table 2-13 summarizes
the capacity analyses for Underground Injected  First Third wastes.

     (1)  K062 Wastes
          EPA determined that between 128 and 148 million gallons of K062
wastes, spent pickle liquor, are underground injected each year   The BOAT
standard for K062 wastes is based on chromium reduction, chemical
precipitation, and sludge dewatering.  Using the TSDR Survey,  EPA identified
only 79 million gallons of available chromium reduction capacity.
Consequently, EPA granted a national capacity variance  to K062 wastes until
August 8, 1990.

     (2)  K049. K05Q. K051. and K052 Wastes
          K049-K052 are petroleum refining wastes.  The BOAT standard for
these wastes is based on sludge incineration or solvent extraction followed by
stabilization.  EPA determined that about 656,000 gallons of these wastes are
underground injected annually.  Based on the limited treatment capacity
available, and the decision to allocate available treatment first to surface
disposed wastes, EPA granted a national capacity variance to underground
injected K049-K052 wastes until August 8, 1990.

-------
     (3)  K104 Wastes
          K104 wastes are wastewaters  generated  from  production  of
nitrobenzene and aniline.  The  BOAT  standard  for K104 wastes was based on
solvent extraction followed by  steam stripping and  carbon  adsorption.  The
TSDR Survey indicates that nearly  57 million  gallons  of K104 are being
underground injected each year.  EPA,  however, identified  only 1 million
gallons of available solvent  extraction  capacity.   Consequently, EPA granted a
national capacity variance to underground  injected  K104 wastes until August 8,
1990.

     (4)  K071 Wastes
          K071 waste is brine purification muds  from  mercury cell production
of chlorine.  The BDAT standard for  K071 is based on  acid  leaching followed by
chemical oxidation, dewatering  of  sludges, and sulfide precipitation of metals
in the effluent.  Although EPA  determined  that only about  45,000 gallons of
K071 waste is underground injected each  year, EPA believes that there is
inadequate capacity to treat  these wastes.  Consequently,  EPA granted a
national capacity variance to underground  injected  K071 wastes until August 8,
1990.

     (5)  K016 Wastes
          K016 waste is heavy ends or  distillation  residues from the
production of certain halogenated  hydrocarbons.   The  BDAT  standard for dilute
(less than 1 percent) K016 wastes  is based on biological treatment followed by
wet-air oxidation; for K016 wastes in  concentrations  equal to or greater than
1 percent, the BDAT standard  is based  on liquid  combustion.  Using the TSDR
Survey, EPA identified 118 million gallons of underground  injected dilute
(less than 1 percent) K016 wastes.   EPA  did not  identify any available
capacity for dilute K016 wastes.   Consequently,  EPA granted a national
capacity variance to underground injected  dilute (less than 1 percent) K016
wastes until August 8, 1990.

     Using the TSDR Survey, EPA identified only  170,000 gallons of underground
injected concentrated K016 wastes  (greater than  1 percent) and 281 million
gallons of available liquid combustion capacity   EPA, therefore, did not
grant a national capacity variance to  underground injected concentrated
(greater than 1 percent) K016 wastes.
                                      2-39

-------
     (6)   K019  Wastes
          K019  is heavy ends or distillation residues 'from the production of
ethylene  dichloride.   EPA determined that only 65,000 gallons of relatively
dilute K019 wastes are being underground injected and that the most
appropriate treatment would be biological degradation.  Using the TSDR Survey,
EPA identified  47 million gallons of available biological treatment capacity.
EPA, therefore, did not grant a national capacity variance to underground
injected K019 wastes.

     (7)   K030  Wastes
          K030  is column bottoms and heavy ends from production of
trichloroethylene and perchloroethylene.  Using the TSDR Survey. EPA
identified 30,000 gallons of underground injected K030.  As with K019, EPA
determined that the underground injected K030 waste is relatively dilute and
is best treated by biological treatment.  EPA, therefore, did not grant a
national capacity variance for underground injected K030 wastes.

     (8)  K103 Wastes
          K103 wastes are residues from the production of aniline.  EPA
determined that 31,560 gallons of K103 waste was being underground injected
annually.  EPA believes that these wastes are relatively concentrated and
would  therefore require liquid combustion.  EPA identified 281 million gallons
of  available liquid  combustion capacity.  EPA, therefore, did not grant a
national capacity variance to underground injected K103 wastes.

2.2.8      Second Third Wastes
           In support of the  Second Third final rule,  EPA performed facility-
level  treatability and capacity analyses on Second Third waste  streams.15
This  subsection  documents  the results  of the  capacity analysis  for the Second
Third  wastes.

     ( 1)  Overview
          EPA finalized  its  regulatory  approach  for  Second  Third wastes on
June 8, 1989. 16   However, EPA did not set standards for all  Second Third
wastes at that time, but instead  allowed  the  soft  hammer  requirements  to  take
effect for those Second  Third wastes  for  which standards  were not promulgated.
In addition, EPA established treatment  standards for  some "soft hammer" First
Third wastes as well as  some wastes  that  were originally  Third Third wastes.

     (2)  All Second Third Wastes
          Table 2-14 presents the estimates of all Second Third wastes  (as
listed in 40 CFR 268.10)  that are land  disposed annually, by management
practice and by type of  disposal  unit.  The total volume  for each category in
Table 2-14 represents  the sum of  all  single Second Third  waste streams and all
waste groups containing  at least  one  Second Third waste but no solvents or
First Third wastes.  This prevents double -counting of multiple waste streams
that contain both Second Third  wastes and solvents or First Third wastes.

     (3)  Second Third Wastes for Which Formal Treatment  Standards Have Been
Promulgated.

          Table 2-15 presents estimates of the volume of  Second Third
promulgated wastes  land  disposed  annually, by management  practice and by type
of land disposal unit.   These estimates include the entire volume of any waste
stream, for both single  waste streams and waste groups, if  the waste stream
contained any Second Third promulgated  waste but no solvent, First Third waste
for which a standard has been finalized,  or California list HOC wastes.  The
estimates also include volumes  for waste  streams containing soft hammer First
Third wastes and Third Third wastes  for which treatment standards were
promulgated in the  Second Third rule.

     The volume of  land  disposed  Second Third promulgated wastes requiring
alternative commercial treatment  capacity is  less  than the  volume of Second
Third promulgated wastes land disposed.   This is because  EPA has assumed that
the 4 million gallons  that were only  stored in impoundments or waste piles do
not require alternative  treatment capacity because they are treated or

disposed of elsewhere (although they may require alternative storage capacity
for more detail on "stored only" waste volumes see Subsection 4.1.1)
Furthermore, the facility-level waste treatability and technology capacity
analyses conducted on Second Third promulgated wastes being land disposed
determined that 22 million gallons of these wastes either had already been
treated or could be treated onsite using the BDAT technology and therefore do
not require alternative commercial treatment capacity.

     Based on this analysis, EPA estimates that 598 million gallons of Second
Third promulgated wastes will require alternative commercial treatment
capacity.  EPA estimates that treatment of the 598 million gallons will
generate 5 million gallons of waste residuals that will require additional
alternative treatment capacity.

     (4)  Surface Disposed Second Third Promulgated Wastes
          Table 2-16 shows the estimates of the volume of surface land
disposed Second Third promulgated wastes that require alternative'commercial
treatment recovery capacity.  These estimates are based on the results of the
TSDR Survey.

     A comparison of required and available treatment/recovery capacity shows
adequate capacity for all surface disposed Second Third promulgated wastes.
However, in order to allow time for facilities to adjust existing cyanide
treatment processes to operate more efficiently,  EPA determined to grant a
30-day variance from the cyanide standards for F006 nonwastewaters and F007,
F008,  and F009 wastewaters and nonwastewaters.

     In addition, because F011 and F012 heat treating wastes are often
commingled with F006, F007,  F008,  and F009 electroplating wastes, EPA expects
that they will have to be segregated and treated separately.  In order to
allow some time to adjust processes to segregate these heat treating (F011,
F012) and electroplating wastes (F006, F007,  F008, F009),  EPA deferred the
total and amenable cyanide standards for F011 and F012 heat treating wastes
until December 8, 1989.  However,  between July 8, 1989, and December 8, 1989,
these wastes were subject to the same cyanide standards as the electroplating
wastes  (F006, F007, F008, F009).

     EPA did not grant a national capacity variance to any other surface
disposed Second Third promulgated wastes.

     (5) Underground Injected Second Third Promulgated Wastes
         Table 2-17 presents the amount of required and available commercial
treatment recovery capacity for underground injected Second Third promulgated
wastes.  The amount of available commercial capacity presented is that amount
remaining after accounting for surface disposed Second Third wastes.  The
amount of available commercial capacity and most of the required capacity were
estimated using the TSDR Survey.  For some waste codes for which the TSDR
Survey did not contain data on the volume being underground injected, EPA used
the Office of Drinking Water's (ODW's) Hazardous Waste Injection Well Data
Base (HWIWDB) to estimate the volume of these wastes underground injected.17

     The table shows shortfalls in available capacity for cyanide destruction,
incineration, and wastewater treatment of organics.  Treatment standards based
on alkaline chlorination were promulgated for F007, F008,  F009,  F011, F012,
F019, P013, P021, P029, P030, P063, P074, P098, P099,  P10A, P106, and P121
wastes.  EPA estimates that about 126 million gallons per year of underground
injected Second Third promulgated wastes will require alkaline chlorination.
However, one F007 waste stream accounts for 126 million gallons  per year of
the required capacity.  Excluding this stream,  adequate capacity exists to
treat the small volumes required for the remainder of these wastes.
Consequently, of the waste requiring alkaline chlorination, EPA  granted a two-
year national capacity variance only for F007 wastes,  which are  underground
inj ected.

     In addition, as previously mentioned, EPA granted a 30-day  variance from
the cyanide standards to F006 nonwastewaters and F007,  F008,  and F009
wastewaters and nonwastewaters.  EPA also deferred the cyanide standards for
F011 and F012 until December 8, 1989.  However, between July 8,  1989, and
December 8, 1989, F011 and F012 wastes were subject to the same  cyanide
standards as the electroplating wastes (F006, F007, F008,  and F009).

     The treatment standard for K009 nonwastewaters is ba=ad on  incineration;
for wastewaters it is based on steam stripping followed by biological
treatment.   In the capacity analysis for K009 wastes, only wastewaters were'
identified as requiring alternative treatment.  Table 2-17 shows that
insufficient wastewater treatment capacity exists for the volume of K009 waste
that is underground injected.   EPA therefore granted a two-year national
capacity variance to underground injected K009 wastewaters.

     The treatment standard for K011 and K013 nonwastewaters is based on
incineration.  Table 2-17 shows that insufficient capacity exists for the
volume of underground injected K011 and K013 nonwastewaters requiring
incineration.  EPA therefore granted a national capacity variance to
underground injected K011 and K013 wastes.

     EPA determined that sufficient capacity exists for the remainder of the
underground injected Second Third promulgated wastes.   However, as previously
mentioned,  to allow time (if any is needed)  for facilities to adjust existing
cyanide treatment processes to operate more  efficiently,  EPA determined to
grant a 30-day variance from the cyanide standards for F006 nonwastewaters and
F007, F008, and F009 wastewaters and nonwastewaters.

     In addition, because F011 and F012 heat treating wastes are often
commingled with F006,  F007,  F008,  and F009  electroplating wastes, EPA expects
that they will have to be segregated and treated separately.   To allow some
time to adjust processes to segregate these  heat treating (F011, F012) and
electroplating wastes (F006, F007,  F008,  F009),  EPA deferred the total and
amenable cyanide standards for F011 and F012 heat treating wastes until
December 8, 1989.  However,  between July 8,  1989, and December 8, 1989. these
wastes will be subject to the same cyanide  standards  as the electroplating
wastes (F006, F007,  F008, F009).

2.2.9     Determination of Available Capacity for the Third Third Final Rule
     This section presents EPA's determination of the amount of commercial
treatment capacity available for Third Third promulgated wastes.

     (1)  Effects of Previous Land Disposal Restrictions
          Table 2-19 shows the effects of previous land disposal restrictions
on available capacity for the Third Third final rule.  The table shows EPA's
latest estimate of available capacity for each technology.  The table also
presents the amount of capacity required by each of the previous land disposal
restrictions in order of promulgation.  The amount required by previous rules
is subtracted from the available capacity for each technology to determine the
amount remaining, and therefore available, for the Third Third promulgated
wastes.

     The 1989 data included in the available capacity analysis of the proposed
Third Third rule were based on facility projections made in 1987 as reported
in the TSDR Survey and limited facility contacts.   For the final rule, EPA
contacted facilities that anticipated additional available capacity for 1989
to verify projected capacities reported in the TSDR Survey.  For alkaline
chlorination followed by chemical precipitation 1989 data have been adjusted
to reflect this new information.

     In addition to the above mentioned revision EPA also revised the
available capacity estimate for combustion of sludge and solids.  During the
public comment period for the proposed Third Third rule, EPA received several
comments on available sludge/solid combustion capacity.   Commenters indicated
that EPA had omitted available units, included units that may not actually be
available, and incorrectly estimated capacity for some units.   Sources of
suggested error included new operating parameters resulting from permits
issued since the TSDR Survey, and new hazardous fuel blending and burning
techniques that increase capacity for reusing sludges and solids as fuel.
Since the statutory deadline for incineration permit decisions passed in
November of 1989, EPA agreed that recent permits could have affected national
incineration capacity   As a result, EPA has obtained updated information from
EPA regional and state environmental regulatory offices (and in a few cases
incineration facility's themselves) and has reevaluated available sludge/solid
combustion capacity based on these data.
                                     2-50

-------
     EPA also made revisions  to available capacity estimates for four
technologies required for the final Third Third rule.  These technologies
include:  1) alkaline chlorination, 2) biological treatment followed by
chemical precipitation;  3) chromium reduction  followed by chemical
precipitation; and 4) chemical precipitation.

     Due to a mathematics error in the Third Third proposed rule, EPA has
revised the available capacity estimate for combustion of liquids.  This
revision had no effect on capacity variances for the final rule.

     (2)  Impacts of Third Third Final Rule on California List HOCs
          The California list final rule for HOCs was not waste code specific,
but instead regulated all hazardous wastes containing HOCs above a specified
concentration.  Consequently, EPA's capacity analysis for HOCs included some
Third Third wastes.  Table 2-19 presents the available capacity for Third
Third Wastes  including Third  Third HOCs.  However, today's final rule is waste
code specific and therefore some overlap exists between the California list
HOC final rule and the Third  Third final rule.  In addition, some of the
technologies  to which Third Third wastes were  assigned for the California list
final rule may not be appropriate as  a result  of today's final rule.

     EPA has  therefore decided to reanalyze all California list HOC wastes
subject to this proposal and  has included these wastes in the estimates of
required capacity as a result of the  Third Third final rule.  In order to
avoid double  counting these wastes, however, EPA has subtracted these wastes
from required capacity estimates for  the California  list HOC final rule

2.2.10    Third Third Promulgated Wastes

     (1)  Overview
          EPA is today promulgating its regulatory approach for Third Third
wastes   In addition, EPA is  promulgating standards  for "soft hammer" First
and Second Third wastes, as well as some wastes that were originally included
as California list HOCs. Those wastes for which EPA is today setting
treatment standards  are  listed in Table 1-1.   These wastes will hereafter be
referred to  as Third Third promulgated wastes.  Waste code-specific capacity
analyses for  the Third Third  promulgated wastes are presented in  Section  3.

     Table 2-20 presents estimates of the volume of Third Third promulgated
wastes land disposed annually, by management practice and by type of land
disposal unit.  These estimates include the entire volume of any waste stream,
for both single waste streams and waste groups, if the waste stream contained
any Third Third promulgated waste but no solvent, or First or Second Third
waste for which a standard has been finalized.  The estimates also include
volumes for waste streams containing soft hammered First and Second Third
wastes for which treatment standards are being promulgated today, as well as
Third Third promulgated wastes previously restricted as California list HOCs

     The volume of land disposed Third Third promulgated wastes requiring
alternative commercial treatment capacity is less than the volume of Third
Third promulgated wastes land disposed.  This is because EPA has assumed that
the 77 million gallons that were placed in short-term storage in waste piles
do not require alternative treatment capacity because they are treated or
disposed of elsewhere (although they may require alternative storage capacity;
for more detail on the approach for "stored only" waste volumes, see
Subsection 4.1.1).  Furthermore, the facility-level waste treatability and
technology capacity analyses conducted on Third Third promulgated wastes being
land disposed determined that 79 million gallons of these wastes either had
already been  treated or could be treated onsite using the BOAT technology and
therefore do not require alternative commercial treatment capacity

     Based on this analysis, EPA estimates that 5,546 million gallons of Third
Third promulgated wastes will require alternative commercial treatment
capacity.  This volume includes 30 million gallons of soils, which are
discussed in  a separate section of this document; therefore, it is estimated
that 5,516 million gallons of nonsoil Third Third promulgated wastes will
require alternative commercial treatment capacity.  Finally, EPA estimates
that treatment of the 5,546 million gallons will generate 86 million gallons
of waste residuals that will require additional alternative treatment
capacity

      (2)  Surface Disposed Third Third Wastes
          Table  2-21 presents the estimates of available commercial capacity
applicable  to surface disposed Third Third promulgated wastes.  The amount  of
available commercial capacity presented is that amount remaining after

accounting for previous land disposal  restrictions  (see Table  2-19)   Table
2-21 also shows the estimates of  the volume  of  surface disposed Third Third
promulgated wastes that will require alternative commercial  treatment recover-.-
capacity as a result of this final  rule  (i.e.,  required capacity excluding
soil and debris).

     A comparison of required and available  treatment/recovery capacity shows
adequate capacity for most of the surface  disposed  Third Third promulgated
wastes.  However, EPA has determined that  insufficient capacity currently
exists for some volumes of surface-disposed  Third Third promulgated wastes.
Insufficient capacity exists for  the following  technologies:   acid leaching
followed by chemical precipitation, sludge/  solid combustion, mercury
retorting, thermal recovery, and  vitrification.  Consequently, EPA is
promulgating a national capacity  variance  for D009,  K106, P065. P092, and U151
low mercury nonwastewaters; F039  multi-source leachate nonwastewaters;  K048 ,
K049, K050, K051, and K052 nonwastewaters; D009, K106, P065, P092, and U151
high mercury nonwastewaters; D008 lead acid  batteries in storage areas prior
to secondary smelting; P087 wastewaters  and  nonwastewaters;  and D004, K031,
K084, K101, K102, P010, P011, P012, P036,  P038, and U136 nonwastewaters.  EPA
is granting these wastes a two-year national capacity variance, except for
K048-K052 nonwastewaters.  EPA  is granting K048-K052 petroleum-refining
nonwastewaters a six-month national capacity variance.

     EPA is not promulgating a  national  capacity variance for any other
surface-disposed Third Third promulgated wastes.  Section 3  1 contains a
detailed capacity analysis for  each Third  Third promulgated  waste code.

     (3)  Underground Injected  Wastes  Included  in Third Third  Rule
     Table 2-22 presents the amount of required and available  commercial
treatment recovery capacity for underground  injected  Third Third promulgated
wastes.  The amount of available  commercial  capacity  presented is that  amount
remaining after accounting for  surface-disposed Third Third  promulgated
wastes

treatment followed by chemical precipitation, chemical oxidation followed by
chemical precipitation, chemical  oxidation followed by chromium reduction and

reactive wastewaters and nonwastewaters; D007 wastewaters and nonwastewaters;
D009 nonwastewaters; D002 wastewaters and nonwastewaters; K011 and K013
wastewaters and K014 wastewaters  and nonwastewaters; and F039 multi-source
leachate wastewaters.

     EPA is not granting a national  capacity variance for any other
underground injected Third Third  promulgated wastes.

     (4)  Soil and Debris

     Table 2-23 presents the amount  of required and available commercial
treatment recovery capacity for  soil and debris wastes.  The  amount of
available commercial capacity presented is that amount remaining after
accounting for surface-disposed  and  underground injected Third Third
promulgated wastes.

     The table shows shortfalls  in  available capacity for incineration,
inorganic solids  debris treatment,  mercury retorting, and vitrification.  EPA
is therefore promulgating an extension of the effective date for certain
contaminated soil and debris for  which the treatment standards promulgated
today are based on incineration,  inorganic solids debris treatment, mercury
retorting, or vitrification.  RCRA  section 3004(h)  (2) allows the
Administrator to  grant an extension  to the effective date based on the
earliest date on  which adequate  alternative capacity will be available, but
not to exceed  two-years ".  .after the effective date of  the prohibition which
would otherwise apply under subsection  (d),  (e),  (f),  or  (g)."  For First
Third and Second  Third wastes that  have heretofore been  subject to the  "soft
hammer" provisions but for which treatment standards are being promulgated
today, EPA  is  interpreting  the statutory language "   .effective date  of the
                                      2-59

prohibition that would otherwise apply"  to be the date treatment standards are
promulgated for these wastes  (i.e., May  8, 1990), rather than the date on
which "soft hammer" provisions  took effect (i.e., August 8,  1988, and June 8,
1989, respectively).  EPA  finds this  the best interpretation for two reasons
Extensions of the effective date are  based on the available  capacity of the
BDAT for the waste, so it  is  reasonable  that such an extension begin on the
date on which treatment  standards based  on performance of  the BDAT are
established.  Furthermore, EPA  does not  intend,  in effect  to penalize
generators of First Third  and Second  Third wastes by allowing less time (i.e.,
28 months and 37 months, respectively) for the development of needed capacity,
while generators of Third  Third wastes in the same treatability group are
allowed the maximum 48 months (assuming  capacity does not become available at
an earlier date).  The promulgated capacity extension would  therefore commence
for  First, Second, and Third  Third wastes on May 8, 1990, and would extend (at
maximum) until May 8, 1992.

     For the purpose  of  determining whether a contaminated material is subject
to this capacity extension, soil is defined as materials that are primarily
geologic in origin, such as silt,  loam,  or clay, and that  are indigenous to
the  natural geological environment.   In  certain  cases, soils will be mixed
with liquids or  sludges.   EPA will determine on  a case-by-case basis whether
all  or portions  of such  mixtures should  be considered soil  (52 FR 31197,
November 8, 1986) .

     Debris is  defined as  materials  that are primarily non-geologic in origin
such as grass,  trees, stumps, shrubs, and manmade materials  (e.g., concrete,
clothing, partially buried whole or  crushed  empty drums, capacitors, and other
synthetic manufactured  items)

     Debris may  also  include  geologic materials  (1)  identified  as  not
 indigenous  to  the natural  environment at or  near the  site,  or  (2)  identified
as  indigenous  rocks exceeding a 9.5  mm sieve  size  that  are greater than  10
percent by  weight,  or that are  at  a  total level  that, based on  engineering
judgement,  will affect  performance of available  treatment  technologies.   In
many cases,  debris  will  be mixed with liquids  or sludges.   EPA will determine
 on a case-by-case basis  whether all  or portions  of  such mixtures should be
 considered debris.
                                      2-61

-------
     Analysis of the TSDR Survey data indicated that a volume of approximately
21 million gallons of soil contaminated with wastes subject  to  this proposal
were land disposed in 1986.   However, the Superfund remediation program has
expanded significantly since that time.   Plans for remediation  at Superfund
sites indicate that the excavation of soil and debris requiring treatment
(including incineration and subsequent land disposal) will be far greater in
1990 than in 1986.  Because of the major increase in the Superfund remediation
program, EPA believes that capacity is still not adequate for combustion of
Third Third contaminated soil and debris.  In addition, the TSDR Survey
indicates that inadequate capacity exists for soils requiring incineration or
mercury retorting.  A two-year extension of the effective date is promulgated
for Third Third contaminated soil and debris for which BDAT is incineration,
inorganic solids debris treatment, mercury retorting, or vitrification.

     EPA notes that if soil and debris are contaminated with Third Third
prohibited wastes whose treatment standard is based on incineration and also
with other prohibited wastes whose treatment standard is based on a non-
combustion type of technology, the soil  and debris would remain eligible for
the national capacity variance.  This is because the contaminated soil and
debris would still have to be treated by some form of combustion technology
that EPA has evaluated as being unavailable at present.  However,  there is one
exception to this principle.  If the soil and debris are contaminated with a
prohibited waste (or wastes) that is no  longer eligible for a national
capacity extension, such as certain types of prohibited solvent wastes, then
the soil and debris would have to be treated to meet the treatment standard
for that prohibited waste (or wastes).   Any other interpretation would result
in EPA's extending the date of prohibition beyond the dates established by
Congress, and therefore beyond EPA's legal authority.

     (5) Mixed Radioactive Wastes
         Table 2-24 presents the amount  of required and available treatment
and recovery capacity for mixed radioactive wastes.   The table shows
shortfalls in available capacity for stabilization,  macroencapsulation,

chlorination, alkaline chlorination followed by chemical precipitation,
treatment of reactives, metals recovery, amalgamation, chromium reduction

followed by chemical precipitation, chemical precipitation, and sulfide
precipitation.  The table also shows a capacity shortfall for soil and debris
contaminated with mixed radioactive wastes.  EPA is therefore granting a  two-
year national capacity variance for First Third, Second Third, and Third  Third
mixed radioactive wastes.

     EPA has defined a mixed radioactive as any matrix containing a RCRA
hazardous waste and a radioactive waste subject to the Atomic Energy Act  (53
FR 37045, 37046, September 23, 1988).   Regardless of the type of radioactive
constituents that these wastes contain (e.g.,  high-level, low-level, or
transuranic),  they are subject to RCRA hazardous waste regulations, including
the land disposal restrictions.

     Radioactive wastes that are mixed with spent solvents, dioxins, or
California list wastes are subject to  the land disposal restrictions already
promulgated for those hazardous wastes.  EPA has determined, however,  that
radioactive wastes that are mixed with First Third and Second Third wastes,
will be included in the Third Third rulemaking (40 CFR 268.12(c)).   Thus,
today's rule addresses radioactive wastes that contain First Third, Second
Third, and Third Third wastes.

     The Department of Energy (DOE) provided data on the generation and
treatment of mixed radioactive wastes  at 21 DOE facilities.  Information  in
Table 2-24 is based on the DOE data.  Other sources for non-DOE mixed
radioactive wastes included the TSDR Survey, Generator Survey, published
studies of mixed radioactive wastes, surveys and reports for states and
interstate compacts for managing low-level mixed radioactive wastes, and
telephone contacts with government representatives and industry officials.
Appendix B describes these data sources in more detail.

     Appendix B of this background document also provides a detailed
discussion of how these data were analyzed.  In general, the first step in the
analysis was a DOE facility-by-facility analysis of mixed radioactive waste
generation.  Generation numbers were developed in groups based on BDATs or
equivalent treatment technologies.  For each treatment technology,  the
quantity of mixed radioactive wastes requiring treatment included the annual
                                     2-64

generation rate and the amount  of  mixed radioactive waste  in storage  requiring
treatment.

     Once generation numbers were  developed,  they were  compared  to available
DOE on-site treatment capacity  to  determine  the  net treatment  capacity for
each technology at each DOE facility.   With  this step accomplished, aggregates
of net treatment capacity  for each treatment  technology were developed for all
of DOE, which indicated a  capacity shortfall.

     Analysis of non-DOE mixed  radioactive waste generation  could not be
performed in a detailed systematic manner, as  data presentation  and definition
varied greatly from source to source.   Available data were analyzed to
determine the types and quantities of  mixed radioactive  wastes generated at
non-DOE facilities.  As a  result of this  analysis,  EPA  determined that the
non-DOE generation of mixed radioactive wastes would have no significant
impact on the outcome of the capaacity analysis  for the  Third Third final
rule, as the quantity of non-DOE mixed radioactive wastes requiring treatment
is less than one percent of the quantity  generated at DOE facilities.   In
addition, RCRA waste codes found in non-DOE mixed radioactive wastes are also
found in DOE mixed radioactive  wastes,  so no  additional  treatability groups
had  to be identified.

     No significant non-DOE treatment  capacity was identified  in the analysis.
Consequently, there is currently a capacity  shortfall for non-DOE mixed
radioactive wastes.

     Because a capacity shortfall  currently  exists for  DOE and non-DOE mixed
radioactive wastes, EPA is granting a  national capacity variance for  all
surface-disposed mixed radioactive wastes.   EPA has no  information on the
underground injection of mixed  radioactive  wastes.  Consequently, EPA is  not
granting a national capacity variance  for mixed radioactive  wastes  that  are
underground injected.
