Mining Waste Exclusion and Definition
of Designated Facility
AGENCY: Environmental Protection
Agency.
ACTION; Proposed rule.	
SUMMARY: In today's notice, EPA
proposes to permanently remove seven
of the 20 conditionally retained mineral
processing wastes from the Bevill
exclusion. Wastes removed from the
exclusion will become subject to
hnardous waste regulations if they are
found to exhibit a hazardous
characteristic or are otherwise identified
or listed as hazardous. In compliance
wllh « Court order, the Agency will
finalize the scope of the Bevill exclusion
for the 20 mineral processing wastes by
January 15,1990. The seven wastes
proposed for removal from the Bevill
exclusion are: roast/leach ore residue
from primary chromite production,
process wnstewater from coal
gasification, furnace off-gas solids from
elemental phosphorus production,
process waatewater from hydrofluoric
acid production, process wastewater
from primary lead processing, sulfate
process waste acids from titanium
dioxide production, and sulfate process
waste solids from titanium dioxide
production. Wastes remaining within the
exclusion will be addressed hi a Report
to Congress and subsequent Regulatory
Determination by January 31,1991.
 * In addition, today's notice contains a
  Sroposnl to modify the RCRA subtitle C
  efMUon of "designated facility" for
purposes of clarifying the requirements
for completing hazardous waste
shipment manifests for transporting
wastes from one state where they are
regulated as hazardous to another in
which they are not regulated as
hazardous.
   Section 3Q01(bH3HA)(ii)  of the
Resource Conservation and Recovery
 Act (RCRA) excludes "solid waste from
 the extraction, beneficiation, and
 processing of ores and minerals" from
 regulation as hazardous waste under
 subtitle C of RCRA, pending completion
 of certain studies by EPA.  In 1980, EPA
 interpreted this exclusion (on a
 temporary basis) to encompass "solid
 waste from the exploration, mining,
 milling, smelting, and refining of ores
 and minerals" (45 FR 70619, November
 19,1980).
   EPA proposed the  criteria by which
 mineral processing wastes would be
evaluated for continued exclusion on
October 20,1988 (53 FR 41288) and
proposed revisions to the criteria on
April 17,1989 (54 FR 15316). On August
18 (see 54 FR 36592; September 1,1989),
EPA published the final criteria, and
took final action on the Bevill status of
all but 20 mineral processing waste
streams.  The Agency conditionally
retained  these 20 mineral processing
wastes within the exclusion from
subtitle C regulation provided by sectibn
3001(b)(3)(A)(ii) of RCRA pending
collection and analysis of additional
information.
DATES: EPA will accept public
comments on this proposal until
November 9,1989. The Agency will hold
a public hearing on October 27,1989
from 9:00 a.m. to 5:00 p.m., unless
concluded earlier.
ADDRESSES: Requests to speak at the
public hearing should be submitted in

   and minerals" (45 FR 76619r November
   19,1980).
     EPA proposed the criteria by wMcn
   mineral processing wastes would be
   evaluated for continued exclusion on
   October 20; 1988 [53 FR 41288) and
   proposed revisions to the criteria on
   April 17, 1989 (54 FR 15318). On
   September 1,1989 (see 54 FR 36592) '
   EPA provided the final Bevill exclusion
   criteria. (See section II of this preamble
   for a complete presentation of the
   definitions of mineral processing and
   beneficiation Wastes and the high
   volume and low hazard criteria.)
    The September rulemaking also
   finalized the Bevill status of nine
   mineral processing waste streams that
   had been proposed either for retention
   within or removal from the exclusion in
  the April 1989 notice. EPA temporarily
  retained for study in the July 1990 Report
  to Congress five wastes within the Bevill
  exclusion:  •    ,
   1. Slag from primary  copper
  processing.
   2. Slag from primary lead processing.
   d. Ked and brown muds from bauxite
  processing.
   4. Phosphogypsum from phosphoric
  acid production.
   5. Slag from elemental phosphorus
  production.
   EPA permanently removed the
 remaining four wastes from the Bevill
 exclusion:
   1. Acid plant and scrubber blowdown
 from primary copper processing -
   2. Acid plan£ blowdown from primarv
 lead processing.
   3. Furnace scrubber blowdown from
 elemental phosphorus production.
   4, Air pollution control scrubber
.blowdown from primary tin processing
   In addition, the Agency modified the
list of mineral processing wastes
proposed for conditional retention in
April 1989. In the September 1989
rulemaking, the Agency conditionally
retained 20 mineral processing wastes

                                   one state is shipped to a facility in a
                                   second state that has not yet regulated
                                   the waste as hazardous. (In fact, EPA
                                   currently interprets the definition of
                                   "designated facility" in this manner.)
                                      EPA solicits public comment on the
                                   data used to make the proposed Bevill

                                    criteria were made final in the
                                    September 1 rule, and were developed
                                    following and in response to comments
A. Definition of Mineral Processing and
Beneficiation
  For purposes of this rule, mineral
processing wastes are generated by
operations downstream of beneficiation
(as defined by the September 1,1989
rule) and originate from a mineral
processing operation as defined by the
following elements:
   (1) Excluded Bevill wastes must be
solid wastes as defined by EPA.
   (2) Excluded solid wastes must be
uniquely associated with mineral
   production.                  ,
     11. Basic oxygen furnace and open
   hearth furnace slag from carbon steel
            or   process waste solids from
    titanium telrachloride production.
      13, Slag from primary zinc processing.
    The Agency will take final action on the
    S» .of *c Bevill exclusion for mineral
    processing wastes by January 15, 1990.
      In addition, the Agency is today
    proposing a clarification to the
    definition of "designated facility to
    alleviate any confusion that the public

                                       This rule proposes the final Bevill
                                     exclusion status of 20 conditionally
                                     retained mineral processing wastes,
                                     based upon information collected by or
                                     submitted to the Agency during recent
                                     months. EPA will take final actioni onL_
                                     the proposed wastes by January 15,1990.
                                     At that time, the final boundaries of the
                                     Bevill exclusion for mineral processing
                                     wastes will be established.
                                        EPA will conduct a detailed study of
                                     all mineral processing wastes retained
                                     within the final Bevill exclusion   .
                                     boundaries. EPA will summarize the
                                     findings of these studies in a Report to
                                     Congress to be submitted by July 31,
                                     1990.
                                        Six months, after submission of this
                                      report, the Agency will publish a
                                      Regulatory Determination stating
                                      whether any of the studied wastes
                                      merits regulation under subtitle C of
                                      RCRA as hazardous wastes, or that such
                                       regulation is unwarranted.

                                       II. The Bevill Exclusion Definitions and
                                       Criteria
                                         On August 18,1989 (See 54 FR 36592;
                                       September 1,1989), EPA finalized the
                                       definitions of mineral processing and
                                       beneficiation wastes and the high
                                       volume and low hazard criteria that the

     would provide that if a waste is sent to
     an authorized state where the waste is
     nol  regulated as hazardous, then the
     designated facility must be a facility
     allowed by the state to accept the
   [Exeas^

 operations that possess all of the
 following attributes:
   a. Follow beneficiation of an ore or
 mineral (if applicable);
   b. Serve to remove the desired
 product from an ore or mineral, or from
 a beneficiated ore or mineral, or
 enhance the characteristics of ores or
 minerals, or beneficiated ores or
 minerals;
   c. Use mineral-value feedstocks that
 are comprised of less than 50 percent
 scrap materials;
    d. Produce either a final mineral
 product or an intermediate to the final
 product; and                    ,
    e. Do not combine the product with
  another material that is not an ore or ^
  mineral, or beneficiated ore or mineral
  (e.g., alloying), do not involve
  fabrication or other manufacturing
  activities, and do not involve further
  processing of a marketable product of
  mineral processing.
    (4) Residuals from treatment of
   excluded mineral processing wastes
   must be historically or presently
   generated and must meet the high
   volume and low hazard criteria in order
   to retain excluded status.  .
     Beneficiation operations include
   crushing, grinding, washing, dissolution,
   crystallization, filtration, sorting, sizing,
   drying, sintering, pelletizing, briquettmg,
   calcining to remove water and/or
   carbon dioxide, roasting in preparation
   for leaching (except where the roasting/
   leaching sequence produces a final or
   intermediate product that does not
   undergo further beneficiation or
   processing), gravity concentration,
   magnetic separation, electrostatic
    separation, flotation, ion exchange,
    solvent extraction, electrowinning,
    precipitation, amalgamation, and heap,
    dump, vat, tank, and in situ leaching.
      Processing operations generally
    follow beneficiation and include
    techniques that often destroy the  ore or
    mineral, such as smelting, electrolytic
    refining, and acid attack or digestion.

    EPA wishes to emphasize that
  operations following the initial
  "processing" step in the production
  sequence are also considered processing
  operations, irrespective of whether they
  involve only the techniques defined
  above as beneficiation. In addition,
  leaching operations that are not
  followed by additional beneficiation/  :
  processing operations are also defined
  as processing operations. Therefore,
  solid wastes arising from such
  operations are considered mineral
  processing wastes, rather than-
  beneficiation wastes.

  B. The High Volume Criterion  "
    High volume mineral processing
  wastes are defined as [1) non-liquid
  mineral processing wastes that were
  generated at an average annual rate
  greater than 45,000 metric tons per year
  per facility during any year between
  1983 and 1988, and (2} liquid mineral
 _ processing wastes that were generated
  at an average annual rate greater than
  1,000,000 metric tons per year per
  facility during any year between i983
  and 1988.
   For the purposes of today's proposed
  rule, EPA used the volume criterion for
  non-liquids to determine if bath, solid
  (e.g., slag,phosphogypsumj and semi-
  solid (e.g., wasfewater treatment sludge)
  materials are high volume. EPA used the
 volume criterion for liquids to determine
 whether wastewaters and other aqueous
 wastes are high volume. EPA employed
 professional judgment in deciding which
 criterion to apply to particular waste
 streams.

 c. The Low Hazard Criterion

 1. The Toxicity and Mobility  Test
   A high volume mineral processing
 waste is not low hazard and, therefore,
 is not eligible for.the temporary
 exclusion from subtitle C requirements"
 provided by the Bevill Amendment
 under the following conditions:
   » Available data indicate that waste
 extracts obtained using EPA Method
 1312 and analyzed using established
 SW-846 method's contain concentrations
 of arsenic, barium, cadmium, chromium,
 lead, mercury, selenium or silver that
 exceed 10Q times the MCL for the
 constituent at two or more, facilities that
'generate the waste, unless:
  i. The waste is generated at five or
 more facilities;, and
  ii. Substantial additional relevant data
 are available and the preponderance of
 these additional data indicate that the
 waste should be considered low hazard,
 wheret
  a. Relevant data are defined as data
 that result from analysis of waste
                            extracts obtained by EPA Methods 1310,
                            1311, and 1312,. ASTM Test Method
                            D3987-81, or comparable procedures -
                            that the Agency has reason to believe
                            produce reliable and representative
                            data; and
                             . b. To be considered substantial, the
                            additional data must characterize the
                            waste at 3 plants (other than the plants
                            where Method 1312 results exceed 100
                            times the MCLs) or at least half of the
                            facilities that generate the waste (other
                            than the plants where Method 1312
                            results exceed ItJO times the MCEs),
                            whichever number of plants is larger.
                              • Constituent concentrations
                            measured in waste sample extracts
                            obtained using Method 1312 are used to
                            determine facility-level values as
                            follows:                  ' '   .
                             i. If data for only one sample of the
                            waste are available, then these data
                            determine the facility-level constituent
                          , concentrations; and
                             ii. If data on two OF more samples are
                           available, then the lower bound of the
                           80 percent confidence interval of the
                           mean of the data * serves as the facility-
                           level constituent concentrations, where
                           the confidence interval is calculated for
                           each waste for each constituent using all
                           results (from all plants generating the
                           waste) available from testing of the
                           waste using Method 1312.

                         .  2. The pH Test
                             A high volume 'mineral processing
                          waste is not low hazard and, therefore,
                          is not eligible for the temporary       "
                          exclusion from subtitle C requirements
                          provided by the BeviH Amendment
                          under the following circumstances:
                             e Fewer than five facilities generate
                          the waste and the pH (determined as
                          required by 40 CFR 261.22) is less than
                          one fl.O) or greater than 13.5 at two or
                          more facilities that generate the waste,
                          or if five or more facilities generate the
                          waste and the pH is less than one (1.0J
                          or greater than 13.5 at 50 percent or
                          more of the facilities that generate the
                          waste.
                            •- pH values measured for waste
                          samples are used to determine facility-
                          level values for individual candidate
                          low hazard wastes as follows:
                            i. If a datum for only one sample from
                          a facility is available, this datum
                          determines the facility-level pH; and
                            1 The 80 percent confidence interval is
                          recommended (guidance) in Chapter 0 on sampling
                          in SW-848 as the confidence interval to be used for
                          evaluating whether wastes pasa or fail regulatory
                          thresholds. Because the low hazard criterion is
                          being used as a screening, teat to remove, wastes
                          that are clearly not low hazard from the Bevill
                          exclusion, EPA fa using the /onrer bound of the 80
                          percent confidence interval So compare with the
                          relevant standards.
    ii. If data on two samples from a
  facility are available, the lower value
  determines the facility-level pH,- and
    iii. If data on more than two samples
  from a facility are available, the median
  value defines the facility-level pH.

  III. Oveiview of Twenty Conditionally
  Retained Mineral Processing Wastes

    This section provides brief
  descriptions of each, of the conditionally
  retained mineral processing wastes. The
  purpose of this discussion is to identify
  the facilities and processing operations
  that generate the waste streams, and,
  where applicable, the component parts
  comprising particular waste streams.
  EPA has previously conditionally
  retained these wastes within the Bevill
  exclusion,  and today is proposing either
  to retain them within or withdraw them
  from the exclusion, based upon the final
  high volume and low hazard criteria
  discussed above. Accordingly, the
  Agency is not seeking public comment
  upon these waste descriptions, but only
  upon the volume and hazard data
  underlying these proposed Bevill
  exclusion decisions. To clarify the scope
  of this and previous notices, in today's
  proposal the Agency generally refers to
  specific wastes arising from
  "processing" or "production"
  operations, as opposed to the more
  specific terminology (e.g., smelting,
 refining) used in the previous proposed
 and final rules. Thus, for example,
 copper or lead slags are generated by
 primary "processing," rather than by
 primary "smelting" or "smelting/
 refining."

 A. Roast/Leach Ore Residue from
 Primary Chromite Production
   The primary chromite industry
 processes chromite ore to produce
 sodium chromate and dichromate, the
 latter of which is the starting point for
 most chromium chemicals used in
 electroplating, chromium metal,
 pigments, dyes, inks, photography,
 leather and wood preserving. The
 hydrometallurgicai process involves
 roasting, leaching, neutralization with
 sulfuric. acid, and filtering; insoluble
 dregs remain {i.e., the chromite ore
 roast/leach residue) that are expected to
 contain traces of soluble chromium. Two
 companies operate one facility each that
 generates chromite ore roast/leach
 residue.

B. GasifierAsh from coal Gasification

  Coal gasification is the process of
converting low grade coal and lignite to
synthetic natural gas of pipeline quality.
The only commercial coal gasification
plant in full operation, in the United

-------
39302
Federal Register / Vol. 54, No.  184 / Monday, September 25,  1989 / Proposed Rules
Slates is the Dakota Gasification
Company's Great Plains Coal
Gasification Plant, located at Beulah,
Mercer County, North Dakota. This
plant employs the Lurgi High Pressure
Coal Gasification Technology.
  Run-of-mino lignite coal is crushed
Slid fed to each gnsifier; steam and
oxygen are introduced at the bottom of
each gasifier to effect the coal
gasification reactions. Ash discharged
from, the gtslfiers is quenched and
slutead by a water jet down a sloped
«li%eway to one of two wet wells and
then pumped to one of two dewatering
bins. Water From the dewatering bins is
recycled within the system and the
dewatercd^osi/ierosA, with a moisture
content of approximately 15 percent, is
discharged and trucked back to the mine
for disposal.
C, Process  Wastavfater front Coal
CaslJicaUon
  Following the processing steps
described above, the hot crude product
gm leaving the gasifiers is cleaned of tar
and dust by cooling in quench vessels,
steam generators, and coolers (See "B.
Gasifier Ash from Coal Gasification"
above for introduction and discussion of
previous steps). The gas stream, which
consists of methane, ethane, hydrogen,
hydrogen sulfide, carbon monoxide,
cnrbon dioxide, and nitrogen, is then
purified of hydrogen sulfide and carbon
dioxide. The purified gas  is methanated
lo convert all the carbon monoxide and
a portion of the carbon dioxide by
reaction with hydrogen to produce
methane. After the methanation step,
the product gas is compressed and dried
for delivery to the pipeline.
   The remaining gas liquor stream is
referred to by the operator of this
facility as "stripped gas liquor or
wastewatcr." The reported management
practice is to include this process
wastewator as part of the makeup water
delivered to the cooling tower.
Df Calcium Sulfate Wastewater
Treatment Plant Sludge from Primary
Capper Processing
   Facilities that process copper ore
cqneenlra to generate various aqueous
waste streams which are typically
 Ipated; the effluent is often released,
and the sludge is either disposed of or
recycled to recover the mineral value.
Two types of wastewater treatment are
known to ba employed at present. These
two types, one using sodium hydroxide
 and the other using calcium oxide or
 hydroxide (lime), generate very different
 proportions of sludge, because sodium
 hydroxide typically precipitates very
 little sludge. Treatment using lime as the
 neutralizing agent generates a relatively
                          large quantity of sludge known as
                          calcium sulfate sludge. At least two
                          facilities are known to use lime and
                          generate calcium sulfate wastewater
                          treatment plant sludge. At least one
                          other facility is known to use sodium
                          hydroxide for wastewater treatment.

                          E. Slag Tailings from Primary Copper
                          Processing
                            The  process of smelting copper ores to
                          fuse the metal value and separate the
                          bullion from the impurities generates
                          slag. Often this slag contains copper at a
                          higher percentage than the original ores.
                          Consequently, several copper processing
                          facilities reprocess this slag using
                          beneficiation-like activities (e.g.,
                          crashing, grinding, washing, and
                          flotation). As a result of this
                          reprocessing, or slag concentration, a
                          residue referred to as slag tailings from
                          primary copper processing is generated.
                          According to industry sources, this     _,
                          material is presently managed along
                          with tailings from beneficiation
                          operations, which are claimed to be very
                          similar with respect to physical and
                          chemical characteristics. Two facilities
                          are believed to generate slag tailings
                          from primary copper processing. One
                          smelter and refinery presently uses a
                          Noranda slag concentrator; the other
                          smelter and refinery employs a mill
                          which crushes, grinds, and floats the
                          slag from the flash furnace, thereby
                          generating slag tailings.

                          F. Furnace Off-Gas Solids from
                          Elemental Phosphorus Production
                             Elemental phosphorus is produced in
                          five plants in Tennessee, Idaho, and
                          Montana. The plants are supplied by
                          nearby phosphate reserves which
                           constitute their principal feed source.
                          Phosphorus, obtained by reduction of
                          phosphate rock, is oxidized to produce
                           high purity phosphoric acid for specialty
                           uses and is^ converted into a variety of
                           phosphorus-containing chemicals and
                           metallic phosphides.
                             Sized phosphate rock, or sintered/
                           agglomerated phosphate rock fines are
                           charged to an electric arc furnace
                           together with coke as a reductant and
                           silica  as a flux. The reduction generates
                           a calcium silicate slag and
                           ferrophosphorus, which are tapped, and
                           carbon monoxide off-gases, which
                           contain volatilized phosphorus. This
                           furnace off-gas materials stream is
                           typically processed to remove
                           impurities, which generates the furnace
                           offgas solids. Phosphorus is removed
                           from the gas stream by condensation in
                           the presence of recirculating water
                           above the melting point of phosphorus.
                           The recirculating water is neutralized,
                           and a purge of "mud" and soluble
impurities is removed and disposed;
these are separate and may be
distinguished from the furnace off-gas
solids. Furnace off-gas solids are
generally referred to as roaster residue,
evaporator residue, precipitator slurry,
or treater dust, depending on the method
of processing the off-gas to remove
impurities.

G. Fluorogypsum from Hydrofluoric
Acid Production

  Hydrofluoric acid, produced at three
facilities in the United States, is used in
a variety of chemical processing and
manufacturing operations. In the
production process, acid-grade fluorspar
is reacted with sulfuric acid in a heated
retort to produce hydrogen fluoride gas.
This gas is purified by scrubbing, and
the hydrogen fluoride gas is condensed.
The chemical is marketed as anhydrous
hydrogen fluoride, a colorless fuming
liquid, or it may be absorbed in water to
form hydrofluoric acid, usually 70
percent hydrogen fluoride. The material
remaining in the retort furnace is
calcium sulfate, commonly known as
fluorogypsum. This waste stream is
stacked in gypsum stacks at one facility;
treated, impounded, dredged, and
landfilled at a second facility; and
stacked and sold at a third facility.

H. Process Wastewater from
Hydrofluoric Acid Production

  The production of hydrofluoric acid
results in the generation of large •
quantities of process wastewater from
cooling, condensing, and fluorogypsum
transport (see "G. Fluorogypsum from
hydrofluoric acid production" above for
an introduction and process
description). Much of the wastewater is
typically recirculated to the system
although part of this waste may be
treated and discharged.

I. Air Pollution Control Dust/Sludge
from Iron Blast Furnaces

  Iron is a basic metal used in diverse •
industrial applications. Iron is a primary
material for most land vehicles and
mobile equipment, ships, and
machinery,  almost all large structures,
 tanks, pressure vessels, piping, and a
variety of cans and containers.
   Iron is produced from ore either by
 blast furnaces or by one of several
 direct reduction processes. The modern
 blast furnace consists of a refractory-
 lined steel shaft in which the charge is
 continuously added to the top through a
 gas seal and preheated air is blown
 through the tuyeres at the bosh near the
 bottom, to be emitted as combustible
 gas (top gas). Molten iron and slag are
 intermittently tapped from the hearth at

                                                                         39303
   the bottom. The top gases emitted from
   the blast furnace must be treated before
   release. Air pollution control (APC)
   devices generate either APC dusts, in
   cases where baghouses or electrostatic
   precipitators are used, or APC sludges,
   in cases where wet scrubbers are used.
  /. Iron Blast Furnace Slag
    Iron blast furnace slag, tapped from   '-
   blast furnaces, is removed and either
   disposed or processed and sold (see "I.
   Air pollution control dust/sludge from
   iron blast furnaces" above for the iron
   sector introduction and process
   description).

  K, Process Wastewater from Primary
  Lead Production
    Lead is ranked fifth in tonnage among
  major metals, after iron, copper,
  aluminum, and zinc. Major properties of
  the metal include: low melting point,
  ease of casting, high density, low
  strength, ease of fabrication, acid  •
  resistance, and chemical stability.
  Traditio'nal uses of lead include storage
  batteries, and sheet lead or cable
  sheathing. Consumption of lead has
  markedly declined recently because of
  the decline in the use of lead for
  gasoline additives. Five lead facilities
  were operating in 1988, consisting of one
  smelter, one refinery, and three smelter/
  refineries.
   Lead processing includes smelting and
  refining. Smelting involves several
  successive processes that convert
  prepared lead ore concentrate into
  impure lead bullion ready for refining.
  Sintered lead ore is introduced into a
  blast furnace with coke, limestone, and
  other fluxing materials. Next, lead
  bullion is drossed. Finally, the drossed
  lead bullion is decopperized. The initial •
  step in the refining process is softening.   .
 .The softened lead bullion is then
  desilvered to remove gold and silver.
  Calcium and magnesium are  then added
  to remove bismuth. Finally, the lead
  bullion is mixed with fluxes to remove
  the remaining impurities..
   Process wastewater is generated at
' many points in the smelting and refining
 of lead, and, for purposes of this rule,
 includes waters generated by slag or
 speiss granulation, contact cooling, and
 at some plants, neutralized acid plant
 blowdown effluent. This waste stream
 does not, however, include wastewaters
 from upstream beneficiation operations
 such as sintering. Industry sources have
 indicated that solids are settled out and
 the water is reused.

 L. Air Pollution Control Dust/Sludge
 from Lightweight Aggregate Production
   Lightweight aggregate is a building
 material that is used in concrete in place
 , of normal stone, and for other purposes.
  Concrete made with lightweight
  aggregate has about the same strength,
  but weighs approximately one-third less
  than normal concrete.
    Lightweight aggregate is made by  ,
  heating certain types of clay, shale, and
  slate in a rotary kiln to a temperature of
  at least 1,950 °F, forcing the materials to
  expand or "bloat". The rotary kilns that
  are used at lightweight aggregate
  facilities and the process itself are very
  similar to those employed in the
  production of cement and lime.
    During production operations, large
 volumes of gas leave the kiln, typically
 containing particulate.matter which
 must be removed using either.dry
 collection techniques or wet scrubber's
 [i.e., APC dust/sludge).

 M. Process Wastewater From Primary
 Magnesium Processing by the
 Anhydrous Process
   Magnesium, a light but relatively
 strong metal, is used as a component of
 transportation equipment, castings, and
 wrought products. The largest use of  ,
 magnesium is in manufacturing -,
 aluminum-base alloys which in tum.are
 used in applications such as beverage
 cans and auto parts.
   There are three active magnesium
 primary processing facilities in the
 United States. Two of the facilities use
 an electrolytic process, and one facility
 uses a silicothermie process.
   The anhydrous process uses calcium
 chloride to remove impurities from the
 brine. After removal of solid impurities,
 the solution is concentrated and then
 solidified as magnesium chloride . •
 crystals in a spray dryer. A heated
 reactor is used to remove impurities and
 the resultant molten magnesium chloride
 is sent to a electrolytic cell where
 crystals are formed. The magnesium
 crystals are recast into ingots.  Process
 wastewaters generated during the
 anhydrous process are acidic (pH<2)
 and are managed in evaporation ponds.

 M Process Wastewater from Phosphoric
 Acid Production

  Commercial grade phosphoric acid
 from wet processing is used primarily as
 a feedstock for the production of
 ammoniated fertilizers and in animal
 feed, with a small portion going to
 chemical processing operations. In the
 wet method, the phosphate rock is
 dissolved in phosphoric acid, to which   '
 sulfuric acid is added. The slurry from
 this operation is sent to filters where the
 solids are collected, washed, and sent to
phosphogypsum stacks. Process
wastewaters are generated at several
points in the wet process, including
phosphogypsum  transport, phosphoric,:
   acid concentration, and phosphoric acid
   temperature control and cooling (e.g.,
   barometric condensers and flash
   coolers).

   O. Basic Oxygen Furnace and Open
   Hearth Furnace Air Pollution Control
   Dust/Sludge From Carbon Steel
   Production

   . The steel industry is'composed of
   three sectors. Large integrated steel
   companies—with blast furnaces able to
   produce iron and basic oxygen furnaces
  further processing iron into steel-
   account for approximately 80 percent of
   the raw steel production. This sector
  produces much of the iron ore, coal, and
  limestone needed in its plants. The
  capacity of these plants has been
  reduced over the past few years.
  Minimills, or market mills, typically use
  electric furnaces and continuous casting
  to produce a limited range of products
  from scrap; specialty mills produce
  relatively small quantities of high
  quality, high value products. Neither of
  these last two sector types produce
  Bevill wastes because they do-not
  typically use ores or minerals as their
  primary feedstockfs). All contemporary
  steelmaking processes convert iron,
  scrap, or direct-reduced iron, or
  mixtures of these, into steel by a refining
  process that lowers the carbon and
  silicon content and removes impurities,
  mainly phosphorus and sulfur. The
  excess oxygen is then neutralized by
.  adding deoxidizing elements such as
  manganese, silicon, or aluminum.
  Exhaust gas from the open hearth and
  basic oxygen furnaces is scrubbed to
  remove gases and particulate matter.
  The scrubbers may be dry collection
  devices, resulting in air pollution control
  dust or wet scrubbers, resulting in a
  sludge (i.e., APC dust/sludge).

 P. Basic Oxygen Furnace and Open
 Hearth Furnace Slag from Carbon-Steel
 Production

   In the open hearth process—the
 dominant steelmaking method in the
 U.S. between 1908 and 1969—a
 relatively shallow bath of metal is
 heated by a flame that passes over the
 bath from burners at one end of the
 furnace while the hot gases resulting
 from combustion are used at the other
 end of the furnace to heat checker-brick
 regenerators (see "O. Basic oxygen
 furnace and open hearth furnace Air
 Pollution Control Dust/Sludge from
 carbon steel production" for additional
process details). Slag is generated
 during the refining process and is
removed and sold or disposed.       .  ;
   The most recently developed      ' ' •
steelmaking. process is the basic oxygen

proctss. In this process, a jet of pure
oxygen Is Injected into the molten metal "
by a Innce of regulated height in a basic
refractory-lined converter. Excess
carbon, silicon, and other reactive
elements are oxidized during the
controlled blows, and fluxes are added
to form a slag which is removed and
processed and sold or disposed.
Q. Sulfat® Process Waste Acids from
Titanium Dioxide Production
  Titanium dioxide is the major end
product manufactured from the
processing of titanium-bearing minerals,
principally ilmcnite and rntile. In
addition, synthetic rulile and titanium-
bearing slagi are used as a feedstock for
producing titanium dioxide pigment.
Environmental problems associated
with the sulfate process led to a closure
of several sulfate pigment plants and
conversion to chloride process
technology at other facilities; in the
United States most of the production
(nine of 11 plants) is by the chloride
process (though sulfate processes
generate half the world's production).
About SO percent of the total U.S.
consumption of TiO* is used hi paints,
while about 25 percent is used in paper
coating. Plastics markets have been
Increasingly important and constitute
about 18 percent of the U.S.
consumption.
  The sulfate process is currently used
by two companies, each owning one
plant. The process uses ilmenite, treated
with strong sulfuric acid at temperatures
up to 180 *C, as a feedstock. The
resultant reaction produces hydrated
Iron sulfate and titanium oxysulfate
(TIOSO<). The sludge is removed, and
the liquid is evaporated in a vacuum.
After cooling, the crystallized hydrous
Iron sulfate is filtered, and the filtrate
concentrated to over 200 gm/1. Low-
lempcralure heating of the TiOSCh
solution results in hydrolysis to titanyl
hydroxide (TIO(OH)*) and sulfuric acid,
a major waste acid stream. The
precipitate is washed with water and
weak sulfuric acid, a second waste acid
stream, to remove trace elements
(particularly heavy metals) and calcined
 to TfOt at 1,000 'C. The highly acidic
waste streams of the sulfate process and
 residual solids are the primary waste
 slnrtms from this process.

S. Chloride Process Waste Solids from  '
Titanium Tetrachloride Production

  Titanium tetrachloride is the major
end product manufactured from the
processing of titanium-bearing minerals,
principally ilmenite and rutile. In
addition, synthetic rutile and titanium-
bearing slags are used as a feedstock for
producing titanium tetrachloride. Most
of the titanium tetrachloride is used to
produce titanium dioxide, the remainder
is used to produce  titanium metal or
chemicals. One firm operates four
titanium tetrachloride plants, while
another operates three facilities, and
four others operate one each. Three of
the companies that own only one plant
principally produce titanium metal.
  The chloride process involves
fluidized roasting and chlorination of
rutile,  synthetic rutile, slag, or
beneficiated ilmenites at about 1,000 °C.
The product formed is a titanium
tetrachloride. This is a volatile chloride
and is collected. The nonvolatile
chlorides are disposed. Further
purification includes the separation of
volatile vanadium  oxychloride by
mineral oil complexing and H2S
reduction. To form titanium dioxide, the
purified TiCU is oxidized with fuel and
ah1 at 985 °C, and the chlorine gas is
recycled. Waste solids are generated as
part of the acid stream from air pollution
control treatment of off-gases.

T. Slag from Primary Zinc Processing

  Zinc is used in many industries for
several purposes. The construction
industry accounts  for approximately 45
percent of zinc consumption, followed
by transportation,  20 percent;
machinery, 10 percent; electrical, 10
percent; and chemical and other
industries 15 percent. Slab zinc is
primarily used for galvanizing and
electrogalvanizing, as well as zinc-base
alloys, brass and bronze alloys, and
rolled zinc.
   Zinc metal production uses either
electrolytic techniques or
pyrometallurgical  techniques to produce
slab from unrefined ore. Only one
facility currently produces zinc using
pyrometallurgy. The pyrometallurgical
zinc smelting process uses a retort and
 condensation operation.  The zinc
 concentrate is first roasted, then
 sintered. The sinter product is retorted
 in a furnace, which drives the zinc off in
 gaseous form. The zinc is condensed
 and refined. The material remaining in
 the retort furnace  is the primary zinc
 processing slag. Part of this slag is re-
 processed to recover mineral values,
 while the remainder is disposed.
 IV. Application of Bevill Exclusion
 Criteria
   EPA applied the Bevill exclusion
 criteria to each of the 20 conditionally
 retained mineral processing wastes in a
 three-step process. First, the Agency
 applied the high volume criteria to the
 available waste generation data for the
*20 wastes. In the second step, the
 Agency applied the low hazard criterion
 to the available waste characteristics'
 data for the wastes. Finally, the Agency
 combined the results from the first two
 steps to determine the proposed Bevill
 status  of the 20 conditionally retained
 mineral processing wastes. Each step is
 discussed separately below.

 A. High Volume Criterion

 1. Methodology

    There were two major sources of
 waste  generation data for the 20
 conditionally retained mineral
 processing wastes: EPA's 1989 National
 Survey of Solid Wastes from Mineral
 Processing Facilities, and data
 submitted in response to EPA's requests
 for public comments published in recent
 proposed mineral waste rulemakings. As
 EPA explained in the September 1 final
 rule, the Agency conditionally retained
 all wastes which appeared to meet the
 high volume  criterion based upon
 information submitted in public  *
 comments on the October and April
 NPRMs. Since, however, the data in
 these public  comments was unsworn
 and unverified, EPA committed to
 evaluating the National Survey data for
 this proposal to confirm the information
 found in public comment. The National
 Survey data  were not available in time
 for use in the September 1 final rule.,
    EPA conducted the National Survey of
 Solid Wastes from Mineral Processing
 Facilities during 1989 under the
 , authority of RCRA §§.3001 and 3007.
 These Sections give EPA the power to
 require facilities to furnish information
  about their generation and management
 , of certain solid wastes (as defined in
  CFR Part 261) for use in regulatory
  development. This past spring, EPA
  collected data from over 200 facilities,
  focusing on 47 wastes generated or.
  received by mineral processing facilities
  that the Agency thought, at the time,
  might be  large volume wastes. The data
  collected include general facility
  information  (e.g., ownership, location,
  and mineral processing operations);
  waste generation characteristics;
  processing units, wastewater treatment
  plants, surface impoundments, and other
  residuals management units that receive
  a candidate  special waste;
  environmental monitoring; and other

-------
                                                                 September 25, 1989  /  Proposed Rules
                                                                        3S305
 related information. The data only cover
 waste generation and management
 practices occurring in 1988,
   The second source of data consists of
 data voluntarily submitted to the
 Agency by the mineral processing
 industry in comments on recent
 rulemakings. The 47 special wastes .
 included in the survey reflected the
 Agency's view of the universe of
 potential Bevill wastes at the time of the
 development of the survey instrument hi
 the fall of 1988. Since that time, the-  -
 Agency has added several wastes to the
 list of candidate special wastes, often in _
 response to data submitted by the
 mineral processing industry—-these
 wastes, therefore, were not included in
 the survey. In these cases, the Agency
 relied on the industry-supplied data in
 order to make its determination of Bevill
 status. In addition, the Agency used the
 industry-supplied data to supplement
 the data obtained in the survey in order
 to determine the highest average annual
 generation rate between 1983 and 1988.
  For each of the conditionally retained
 wastes, EPA divided the total 1988
 sector-wide waste generation quantity
 obtained in the survey by the number of
 facilities that generated the waste
 during 1988. For wastes that did not
 meet the high volume threshold for 1988,
 EPA analyzed the responses to the
 survey questionnaire in more detail, to
 determine whether the 1988 data might
 be anomalous (e.g., production and
 waste generation rates were below
 normal due to plant renovations or labor
 strikes]. The Agency then reviewed the
 information submitted in public
 comment (the basis for many of the
 proposed conditional exclusions]  in an
 attempt to reconcile  any significant
 discrepancies. In cases where
normalized waste generation data as
reported for 1988 are in reasonable
agreement with the information
  submitted in public comment, the
  Agency has accepted the waste
  generation rates provided by
  commenters and concluded that the
  waste(s) in question pass the high
  volume criterion. In cases where these
  data are not in agreement, however,
  EPA has tentatively concluded that the
.  materials in question are not high
  volume mineral processing wastes, and,
  accordingly, has proposed to remove'
  them from the Bevill exclusion in today's
  notice. The data and calculations
  underlying EPA's determinations of high
  and low volume mineral processing
  wastes are presented in a background
  document that may be found in the
  docket for this proposed rale.
   Representatives of facilities that
 generate wastes  that have been
 proposed for removal from Bevill on the
 basis of volume that believe that the
 data that they submitted for 1988 do not
 reflect waste generation rates
 throughout the period from 1983 to 1988
 must submit information fully
 documenting this claim by the close of
 the public comment period for this
 proposal November 9,1989.
 Documentation should include a
 description of the production process(es)
.generating the waste (a process flow
 diagram is strongly recommended], the
 specific pointfs] in the mineral
 processing sequence that give rise to the
 waste, the waste generation rate and
 physical state (including percent solids),
 and management practice information
 (through final disposition of the material
 in question].

 2. Results of Applying the High Volume
 Criterion
  Table 1 summarizes the results of
 applying the high volume criterion to the
 available waste generation data for the
20 conditionally retained wastes. The
 average waste generation data reported
 in Table 1 do not, in all cases, reflect
 information collected from all facilities
 generating a particular waste, because
 in responding to the National Survey,
 many facility operators designated-their
 waste generation rates Confidential
 Business Information (CBI]. In no case,
 however, would including CBI waste
 generation data in this table influence
 the results of EPA's application of the
 high volume criterion, i.e., the CBI data
 hi EPA's possession support the
 determinations that the Agency has
 made here regarding compliance with
 the Bevill mineral processing wastes
 high volume criterion.
   Of the 14 non-liquid mineral
 processing wastes, only two were not
 generated at an average annual rate
 greater than 45,000 metric tons per year,
 during one or more years between 1983
 and 1988. These two wastes, therefore,
 fail the high volume criteria and do not
 qualify for the Bevill exclusion:
   1. Furnace off-gas solids from
 elemental phosphorus production
   2. Sulfate process waste solids from
 titanium dioxide production
   Of the six liquid-mineral processing
 wastes, three were not generated at an
 average annual rate greater than
 1,000,000 metric tons per year, during at
 least one year between 1983 and 1988.
 These wastes, therefore, fail the high
 volume criteria and do not qualify for
 the Bevill exclusion:
   1. Process wastewater from coal
 gasification
   2. Process wastewater from
 hydrofluoric acid production
   3. Process wastewater from primary
 lead processing
  In summary, 15 of the 20 conditionally
retained wastes satisfy the high volume
criterion. The Agency proposes to
remove the conditional Bevill status for
the five low volume wastes listed above.

  90 percent of the regulatory level.
~" Because no Method 1312 constituent
  concentrations exceed 100 times MCLs
  for this waste, EPA concludes that it
  passes the low hazard criterion.
    e. Slag Tailings from Primary Copper
  Processing. Two primary copper
  smelters were included in the sampling
•  study. From each facility, one sample of
  slag tailings was collected and
  analyzed. Most constitutents measured
  were below detectable limits using the
  SPLP method, but some detectable
  levels were noted (e.g., for lead).
  Because no Method 1312 constituent
  concentrations exceed 100 times MCLs
  for this waste, EPA concludes that it
  passes the low hazard criterion.
   f. Furnace Off-Gas Solids From
 Elemental Phosphorus Production. Two
 facilities were included in the sampling
  study. One sample  of off-gas solids from
 each facility was collected and
 analyzed. Most constituents were below
 detectable limits using the SPLP method,
 but some detectable levels  were noted.
 The SPLP procedure for cadmium
 generated values from about 5 percent
 up to 249 percent of the regulatory level
 (100 times MCL). Lead analysis
 concentrations ranged from about 10 to
 20 percent of the regulatory level.
 Because the lower 80th percentile
 confidence limit for all constituent
 concentrations was below 100 times
 MCLs for this waste, EPA concludes that
 it passes the low hazard criterion.
   g. Fluorogypsum from Hydrofluoric
 Acid Production. Three facilities were
 included in the sampling  study. One
 sample of fluorogypsum from each
 facility was collected and analyzed.
 Most constituents were below
 detectable limits. Barium was found at
 below 1 percent of the regulatory level
 (100 times the MCLs) in the SPLP
 procedure. Cadmium levels ranged from
 below detectable to 6 percent of the
 regulatory levels in  the three samples.
 Chromium and lead levels were similar,
 ranging from below detection up to
 about 60 percent of  the regulatory level.
 Mercury was found in concentrations of
 about 2 percent of the regulatory level in
 the SPLP procedure. Because no Method
 1312 constituent concentrations exceed
 100 times MCLs for this waste, EPA
 concludes that it passes the low hazard
 criterion.
  h. Process Wastewater From
Hydrofluoric Acid Production. Two _  ' -
facilities were included in the sampling
study. One sample of wastewater from
each facility was collected and
analyzed. Most constituents were below
detectable limits. Arsenic levels ranged
from 2 up to 20 percent of the regulatory
level (100 times the MCLs), while barium
levels were at or below 1 percent of the
  regulatory level. Chromium
  concentrations were from 20 to 56
  percent of the regulatory level in both
^  procedures. Lead was found from 10 to
  61 percent of the regulatory level for the.
  SPLP procedure. Mercury levels were
  below 1 percent of the regulatory level.
  Because no Method 1312 constituent
  concentrations exceed 100 times MCLs
  for this waste, and because all pH
  measurements of the waste were greater
  than 1.0, EPA concludes that it passes
  the low hazard criterion.
    /. Air Pollution Control Dust/Sludge
  From Iron Blast Furnaces. Four facilities
  were included in the sampling study.
  One sample from each of three facilities,
  and two samples from the remaining
  facility were collected and analyzed, for
  a total of five samples. Most
  constituents were below detectable
  limits for the SPLP method. Barium
  levels ranged from below detection to .
  about 1 percent of the regulatory level.
  Cadmium aiid lead were not detected.
  Mercury levels ranged from below
  detection up to 1 percent of the
  regulatory level. Because no Method
  1312 constituent concentrations exceed
  100 times MCLs for this waste, EPA
  concludes that it passes  the low hazard
  criterion.
   / Iron Blast Furnace Slag. Four
  facilities were included in the sampling
  study. One sample  of slag from each of
  two facilities was collected and
  analyzed, while two samples from the
  third facility,  and three samples from the
  remaining facility, were collected and   •
  analyzed, for a total of seven samples.
 Most constituents were below
 detectable limits. Barium and mercury
 levels ranged from below detection to
 about 1 percent of the regulatory levels.
 Because no Method 1312 constituent
 concentrations exceed 100 times MCLs
 for this waste, EPA concludes that it
 passes the low hazard criterion.
   k. Process Wastewater from Primary
 Lead Processing. Three facilities were
 included in the sampling study. From
 each facility, one sample of wastewater
 was collected and analyzed. Most •
 constituents measured were below
 detectable limits. Arsenic levels ranged
 from two to 400 percent of the regulatory
 level (100 times the  MCLs). Barium
 concentrations were below three
 percent of the regulatory level when
 detected. Cadmium levels ranged from
 33 percent up to almost 700 percent of
 the regulatory level. Lead ranged from
 about five percent up to about 145
 percent of the regulatory level. Mercury
 concentrations were generally not
 detectable, and did not exceed 1 percent
 of the regulatory level otherwise.
 Selenium levels ranged from below
 detection up to about 13 percent of the
  regulatory level. All field pH  -
  measurements were above 1.0. Because
  the lower 80th percentile confidence
  limit for a constituent exceeds
  regulatory levels at two different
  facilities (arsenic and cadmium,
  respectively), i.e., two facilities fail the
  low hazard criterion, EPA tentatively
  concludes that this waste stream fails
  the low hazard criterion.
    L Air Pollution Control Sludge/Solids.
  From Lightweight Aggregate Production.
  Two facilities were included in the
  sampling study; however, the data from
  one facility are CBI and cannot be
  reported. One sample of sludge was
  collected and analyzed from the non-
.  CBI facility. Again, all constituents
  except barium were below detectable
  limits using the SPLP method. Barium
  levels for this facility were below 1
  percent of the regulatory level,. Because
  no Method 1312 constituent
  concentrations exceed 100 times MCLs
  for this waste, EPA concludes that it
 • passes  the low hazard criterion.
    m. Process Wastewater From Primary
  Magnesium Processing by the
  Anhydrous Process. One primary
  magnesium processing facility was
  included in the sampling study. From
  this facility, one sample, of wastewater
  was collected and analyzed. Most
  constituents were not above detectable
  levels. Barium, chromium, and lead were
  below detection. Mercury was detected
,  in the sample, but at less than 1 percent
  of the regulatory level. Because no
  Method 1312 constituent concentrations
 . exceed  100 times MCLs for this waste,
  and because all field pH measurements
  were above 1.0, EPA concludes that the
 waste passes the low hazard criterion.
   n. Process Wastewater From
 Phosphoric Acid Production. Two
 facilities were included in the sampling
 study. Three samples of wastewater
 from one facility, and four samples from
 the other facility were collected and
 analyzed, for a total of seven samples.
 Most constituents were below
 detectable limits. Arsenic levels ranged
 from below detectable to about 38
 percent  of the regulatory level, while
 barium concentrations ranged from
 below detection up to about l.percent of
 regulatory levels. Cadmium and
 chromium concentrations ranged from
 about 20 percent up to about 60 percent
 of the regulatory levels. Lead values
 ranged from below detection up to about
 3 percent of the regulatory level.
" Mercury concentrations were below
 detection limits. Because no Method
 1312 constituent concentrations exceed
 100 times MCLs for this waste, and
 because all field pH measurements were

above 1.0, EPA concludes that the waste
passes the low hazard criterion.
  o, Basic Oxygon and Open Hearth
Furnace Air Pollution Control Dust/
Sludge From Carbon Steal Production.
Three futilities were Included in the
wtmpling study. One sample from each
of the first two facilities and two
samples from the third facility were
collected and analyzed, for a total of
four samples. Must constituents were
below detcqteble limits. When barium
«nd mercury levels were detectable,
Ihty remained below 1 percent of the
regulatory levels. Cadmium  and lead
concentrations wore below detection.
Because no Method 1312 constituent
concentrations exceed 100 times MCLs
for this waste, EPA concludes that it
pusses the low hazard criterion,
  fk Basic Oxygen and Open Hearth
Furnace Slag From Carbon Steel
Production* Three facilities were
included in the sampling study. One slag
sample from the first facility, two
samples from the second facility, and
thrw  samples from the third facility
wcrt  collected and analyzed, for a total
of six samples. Most constituents were
below detectable limits. Barium and
mercury concentrations ranged from
below detection to well below 1 percent
of the regulatory levels. Selenium was
below detection. Because no Method
1312 constituent concentrations exceed
100 times MCLs for this waste, EPA
concludes that it passes the  low hazard
criterion.
  q, Sulfate Process Waste Acids From
Titanium Dioxide Production. Two
facilities were included in the sampling
study. From each facility, one sample of
waste acids, was collected and analyzed.
Most  constituents were below
detectable limits. Chromium levels,
                                      however, were found to range from
                                      about 700 percent to 1600 percent of the
                                      regulatory level, i.e., exceeded the
                                      regulatory level at both facilities.
                                      Concentrations of selenium also exce'ed
                                      the criterion at one facility. This waste,
                                      as sampled, also had an extremely low
                                      pH. Because of this uniformly Ipw pH
                                      (< 1) and the relatively high metals
                                      concentrations, EPA has tentatively
                                      concluded that this waste fails the low
                                      hazard criterion.
                                        r. Sulfate Process Waste Solids From
                                      Titanium Dioxide Production. Two
                                      facilities were included in the sampling
                                      study. From each facility, one sample of
                                      waste solids was collected and
                                      analyzed. Concentrations of all
                                      constituents evaluated for the low
                                      hazard criterion were below detectable  ,
                                      limits and regulatory levels. Because no
                                      Method 1312 constituent concentrations
                                      exceed 100 times the  MCLs for this
                                      waste, EPA concludes that it passes the
                                      low hazard criterion.
                                        s. Chloride Process Waste Solids
                                      From Titanium Tetrachloride
                                      Production. Three facilities were
                                      included in the sampling study. From
                                      eaph facility, one sample of waste solids
                                      was collected and analyzed. Most
                                      constituents measured were below
                                      detectable limits. Barium levels ranged
                                      from below detectable up to 2.5 percent
                                      of the regulatory level (100 times the
                                      MCLs). Chromium levels ranged from
                                      below detection up to 2,000 percent of the
                                      regulatory levels.  Lead levels ranged
                                      from below detection up to about 1,000
                                      percent of the regulatory level. Even
                                      when mercury levels were detectable in
                                      the SPLP procedure, they did not exceed
                                      1 percent of the regulatory level. Silver
                                      levels were generally below detection
                                      f9r both procedures, but did range up to
30 percent of the regulatory level in the
SPLP procedure. Importantly, the
constituent concentrations that
exceeded regulatory levels for this
waste all came from the same sample,
and only the lower 80th percent
confidence intervals for constituents
applied to this facility exceed regulatory
levels. Therefore, because only one
facility failed the low hazard criterion
while two facilities passed, EPA has
concluded that this waste stream passes
the low hazard criterion.
  t. Slag From Primary Zinc Processing.
The single facility from this sector
known to generate this waste was
included in the sampling study. From
this facility, one sample of slag was
collected and analyzed. Only one
constituent (barium) was found at
•detectable levels, but its concentration
was below 1 percent of the regulatory
level. Because no Method 1312
constituent concentrations exceed 100
times MCLs for this waste, EPA
concludes that it passes the low hazard
criterion.

3. Summary of Results
  Table 2 summarizes the results of
applying the low hazard criterion to the
available waste generation data for the
20 conditionally retained wastes. The
sampling data indicate that all but three
of these wastes satisfy the low hazard
criterion. Accordingly, EPA is proposing
to remove the following wastes from the
conditional Bevill exemption, pending a
final  rulemaking by January 15,1990:
  1. Roast/leach ore residue from
primary chromite production
  2. Process wastewater from primary
lead processing
  3. Sulfate process waste acids from
titanium dioxide production

 C. Consolidation of Results
   In order for a mineral processing
 waste to qualify for continued retention
 in the Bevill exclusion, it must meet both
 the high volume and the low hazard
 criteria. Combining the results from the
 volume and hazard assessments yields
 the proposed list of temporarily
• excluded mineral processes wastes,
 which are presented and discussed in
 section V, below.

 V. Proposed Bevill Status of Twenty
 Conditionally Retained Mineral
 Processing Wastes

 A, Wastes Proposed for Retention
 within the Exclusion

   Based on applying the Bevill exclusion
 criteria to the available data for each of
 the 20 conditionally retained wastes,
EPA proposes to retain 13 mineral
processing wastes within the exclusion,
and remove the remaining seven. The
proposed status of each of the 20 wastes
and the basis for EPA's proposed Bevill
exclusion decisions are presented in
Table 3. The list of temporarily excluded
Bevill mineral processing wastes in the
proposed regulatory language below (40
CFR 261.4(b)(7) [i)-(xviii)) includes 18
wastes: the five retained in the
September 1 final rule and the 13
proposed for retention today.

B. Wastes Proposed for Removal from
the Exclusion
  EPA proposes to permanently remove
the remaining seven wastes from the
Bevill exclusion:
  1. Roast/leach ore residue from
primary chromite production
  2. Process wastewater from coal
gasification
  3. Furnice off-gas solids from
elemental phosphorus production
  4. Process wastewater from
hydrofluoric acid production
  5. Process wastewater from primary
lead processing
  6. Sulfate process waste acids from
titanium dioxide production
  7. Sulfate process waste solids from
titanium dioxide production
  EPA will make final Bevill exclusion
decisions on these wastes by January 15,
1990. The Agency solicits public
comment on the data used in today's
proposed rule. The Agency will not,
however, respond to comments that
concern the content of the actual
criteria; these criteria are now in final
form.

VI, Regulatory Implementation and
Effective Dates of the Final Rule
  In accordance wilh the March 14,1989
order of the U.S. Court of Appeals for
the D.C, Circuit, EPA intends to finalize
this proposed rule by January 15,1900.
(See En viroiimental Defense Fund v.
EPAt 852 F.2d 1318 (D.C. Cir. 1988)). As
of the effective date of the final rule (i.e.,
six months after the final rule appears in
the Federal Register), all mineral
processing wastes that have been
conditionally excluded from regulation
under Subtitle C of RCRA since 1980,
except the thirteen wastes described
above in Section V, may be subject to
Subtitle C requirements in those states
that do not have authorization to
administer their own hazardous wastes
program in Heu of EPA. Generators,
transporters, and treatment, storage, and
disposal (TSD) facilities in authorized
states wilt be subject to RCRA
requirements imposed as a result of the
final rale only after the state revises its
program to adopt equivalent
requirements and EPA authorizes the
revision.
  The requirements imposed as a result
of removing the temporary exclusion
include; determining  whether the solid
waste(s) exhibit hazardous
characteristics (40 CFR 282.11)  and, for
those wastes that are hazardous;
obtaining an EPA identification number
for managing hazardous wastes (40 CFR
282,34): complying with recordkeeping
and reporting requirements (40 CFR
282,40-282.43); and obtaining interim
status and seeking a  permit (or
modifying interim status, including
permit applications or modifying a
permit, as appropriate) (40 CFR Part
270),
A, Section 3010 Notification
  Not later than 90 days after
publication of the final rule, all persons
who generate, transport, treat, store, or
dispose of wastes that are removed from
temporary exclusion by that rule and
fire characteristically hazardous under
40 CFR part 281 subpart C will  be
required to notify either EPA or an
authorized state of these activities
pursuant to section 3010 of RCRA.
Notification instructions are set forth  in
                          45 FR 12746. Persons who previously
                          have notified EPA or an authorized state
                          of their activities pursuant to Section
                          3010 of RCRA, i.e., persons who
                          previously have notified EPA or an
                          authorized state that they generate,
                          transport, treat, store or dispose of
                          hazardous waste and have received an
                          identification number (see 40 CFR
                          262.12, 263.11 and 265.1) need not re-
                          notify.2 Persons without EPA
                          identification numbers  are prohibited
                          from transporting, offering for transport,
                          treating, storing, or disposing of
                          hazardous wastes.
                            The Agency views the section 3010
                          notification requirements to be
                          necessary in this case because it
                          believes that many persons that manage
                          the wastes coming into subtitle C
                          regulation today have not previously
                          notified EPA and received an EPA
                          identification number.
                          B. Definition of Designated Facility
                            The Agency has received a number of
                          inquiries regarding waste shipments
                          from a state where a waste is subject to
                          hazardous waste regulations to a state
                          where the waste is not yet regulated as
                          hazardous. This situation can arise
                          when EPA lists or identifies a new
                          waste as hazardous under its pre-
                          HSWA authority. In such a case, the
                          waste is subject to RCRA hazardous
                          waste regulations only in those states
                          that do not have interim or final
                          authorization to operate the RCRA
                          program. In a state authorized by EPA to
                          operate a hazardous waste program in
                          lieu of the Federal program under the
                          authority of section 3006 of RCRA, the
                          waste would not be subject to RCRA
                          requirements until the state revises its
                          program to classify the waste as
                          hazardous and received authorization
                          for these requirements. This set of
                          circumstances results from the fact that
                          RCRA allows states a specified time to
                          adopt new regulations in order to
                          minimize disruptions to the
                          implementation of authorized state
                            2 Under the Solid Waste Disposal Amendments of
                           1980, (Pub. L. 96-462) EPA was given the option of
                           waiving the notification requirement under section
                           3010 of RCRA following revision of the section 3001
                           regulations, at the discretion of the Administrator.
 programs. In contrast, this situation does
 not occur when the wastes are newly
 listed or identified pursuant to the
 HSWA authorities since Congress
 specified that HSWA provisions are to
 be implemented by EPA in all states
 until such time as states are authorized
 to implement the new regulations.
   There are two recent EPA rulemakings
 that listed or identified additional
 wastes pursuant to pre-HSWA
 authority. (1) Six Metal Smelting
 Wastes, 53 FR 35412, September 13,
 1988, and (2) Bevill Mining Waste
 Exclusion final rule 54 FR 36592,
 September 1,1989. In addition, today's
 proposed rule on the 20 conditionally
 exempt Bevill wastes could lead to a
 final rule that brings additional wastes
 into RCRA Subtitle C jurisdiction. These
 three rulemakings will result in the
 scenario described above.
   Generators of hazardous waste have
 asked the Agency whether they can ship
 the waste to a facility in a state where it
 is not regulated as hazardous and, if so,
 how they should manifest their waste.
 EPA's generator regulations require a
 generator of hazardous waste to
 "designate on the manifest one facility
 which is permitted to handle the waste
 'described on the manifest." (See 40 CFR
 260.20). The regulations clearly state
 that the facility designated on the
 manifest is the "designated facility"  as
 defined in § 260.10. (See the direct
 reference in the definition of
 "designated facility" to the manifest  ,
 requirement in § 262.20.)
   A designated facility as currently
 defined in 40 CFR 260.10 must either (1)
 have an EPA permit (or interim status)
 in accordance with Parts 270 and 124, (2)
 have a permit from a State authorized in
 accordance with part 271, or (3) be a
 recycling facility that is regulated under
 § 261.6(c)(2) or subpart F of part 266, and
 must also be designated on the manifest
 by the generator pursuant to § 262.20. It
 has become apparent that when
 promulgated in 1980, the definition of
 "designated facility" did not
 contemplate the above situation which
 has potentially broad impacts on the
, RCRA program. EPA's current
 interpretation of this manifest

                                                                       "39311
 requirement is that the authorized state
 determines which facilities are allowed
 to accept the waste. However, since
 questions on this issue have arisen, the
 Agency is using this opportunity to seek
 public; comment and, based on these    ;.-
 comments, to promulgate clearer
 regulatory language.
  The Agency has decided to propose a
 clarification of the definition of
 "designated facility" to alleviate any
 confusion that the public and the
 regulated community may have over its
 applicability. Today's proposal would
 provide that if a waste is sent to an
 authorized State where the waste is not
 considered hazardous, then the
 designated facility must be a facility
 allowed, by the State, to accept the
 waste. This regulatory change would
 only apply to the situation where a
 hazardous waste in one state is shipped
 to a second state that has not yet been
 authorized to regulate the waste as
 hazardous. The effect of the proposed
 rule change would be to clarify the
 Agency's position that the management
 standards of the receiving state are the
 standards applicable to the treatment,
 storage, or disposal of the waste.
  It should be further emphasized that
 the effect of this new provision would
 be limited to a temporary period of time
 following an EPA regulatory action that
 newly identifies a hazardous waste
 pursuant to pre-HSWA authority. All
 authorized states are required to adopt
 EPA's new waste listings and
 identifications by specified deadlines
 (generally one to two years after the
 applicable "cluster" deadline for state
 authorization). Once a state has
 obtained authorization for the new
 waste listings, all RCRA waste
 management standards will apply. The
 phase-in period allowed for state
 adoption  of Federal program changes is
 a basic premise of pre-HSWA state
 authorization. Commenters should also
 be aware that since state programs are
 allowed to include provisions which go
'beyond the Federal program, any
 existing state requirements would
 continue to be applicable and
 enforceable by the state during this
 interim period.
  Without a mechanism to allow
 phasing-in of RCRA standards, new
 Federal program requirements—
 particularly new waste listings or
 identifications—could result in
 unworkable situations. Generators in
 unauthorized states may not be able to
 find a facility that is eligible to take their
 newly listed or identified wastes. This
 could occur if there are no facilities
 within the state that qualified for interim
 status or received a permit modification
for the new waste. Alternatively, if the-
generator has an existing arrangement
to send its waste to a facility in an
authorized state, the receiving facility
would Jiave no opportunity to gain
interim status until its state adopts the
waste stream as hazardous. EPA
believes that the phase-in of the RCRA
program that has been established for
state assumption of the new Federal
requirements is essential for a workable^-
national hazardous waste management
system.-
  The Agency solicits comments on this
proposed clarification of the definition
of "designated facility." In particular,
EPA would like to know if generators
and waste management facilities have
encountered problems with their waste
shipments to  authorized states as
discussed above.
  The Agency also solicits comments on
alternative approaches to this problem.
One option would be to  require  the
receiving facility to be permitted,
licensed, registered, or otherwise subject
to a prior approval program by a state to
manage municipal or industrial solid
waste. This would be similar to the
existing requirement for small quantity
generator-waste in § 261.5(g)(3).
However, this option may present some
of the same drawbacks as the existing
"designated facility" definition in that it
might not be clear-what constitutes an
adequate state-prior approval scheme.
  This proposed clarification will not
alter the requirement that a generator
offer his Waste only to transporters who
have EPA identification numbers. (See
40 CFR 262.12(c)). Thus, if a newly listed
waste is transferred between
transporters in a state where the waste
is not yet hazardous, both transporters
should be identified on the manifest.
The initial transporter would still be
required to keep the copy of the
manifest on file.
  In order to ensure that the waste
reaches the designated facility, EPA is
proposing to require that the generator
arrange that the designated facility
owner or operator sign and return the
manifest to the generator, and that out-
of-state transporters  sign and foward
the manifest to the designated facility.
The return of the manifest to the
generator will "close the loop" on the
disposition of the generated waste and
allow the generator to attempt to resolve
any discrepancies in the manifest, as
required by 40 CFR 262.42. This new
requirement parallels the requirements
in 40 CFR 264.71 and 265.71. However,
as opposed to those sections, which
require the receiving facility to return
the manifest,  the proposed § 262.23(e)
puts the burden on the generator to
 ensure the return of the manifest when
 the waste is sent to a facility in a state
 not yet authorized to treat the waste as
 hazardous. EPA believes that this
 approach is appropriate,  since the
 facility receiving the waste and any out-
 of-state transporters may not be subject
 to subtitle C regulation, if they do not
 otherwise handle any RCRA hazardous
 wastes. It should be noted that with this
 approach the designated  facility and
 out-of-state transporters would not be
 required to obtain EPA identification
 numbers since the waste  is not
 hazardous in their state. (Of course,
 once the state becomes authorized to
 treat the particular waste as hazardous,
 the facility would need a RCRA subtitle
 C permit (or interim status) to continue
 managing the waste and all transporters
 would need EPA identification
 numbers.)
 , The Agency intends to  review the
 comments on today's proposed changes
 to the "designated facility" definition,
 and will promulgate a final rule with the
 associated mining waste  final rule. EPA
 believes that it is important to clarify
 the existing regulation so that the
 parties affected by non-HSWA waste
 identifications and listings know the
 status of these wastes and the
 management standards that apply to
 them if they cross state borders. A minor
 technical correction is also included in
 the proposed language of "designated
 facility" to clarify that an interim status
 facility in an authorized state may be a
 designated facility. EPA believes that it
 is universally understood that these
 interim status, facilities can accept
 hazardous waste shipments, and this
 was the original intent of the provision.
 Therefore, in the first sentence of the
 proposal a parenthetical clause is added
 with the words "or interim status".

 C. Compliance Dates

 \. Interim Status and Permit
 Modifications in Unauthorized States

  Facilities that currently treat, store, or
 dispose of wastes that have been
 removed from temporary  Bevill
 exclusion and are characteristically
 hazardous under 40 CFR part 261,
 subpart C, but have not received a
 permit pursuant to section 3005 of RCRA
 and are not operating pursuant to
 interim status, may be eligible for
 interim status (see section
 3005(e)(l)(A)(ii) of RCRA, as amended).
 In order to operate pursuant to interim
 status, such facilities must submit a
 Section 3010 notice pursuant to 40 CFR
 270.70(a) within 90 days of publication
 of the final rule, and must submit a Part
A permit application within six months

Federal Register / Vol. 54, No. 184 / Monday, September 25, 1989  /  Proposed Rules
of publication of tha final rule. Under
section 3005{e)(3), land disposal
facilities qualifying for interim status
under section 3005(e}(l)(A)(5i) must also
submit a Part B application and certify
that the fuclllty is fa compliance with all
applicable ground water monitoring and
financial responsibility requirements
within 18 months of publication of the
final rule. If tha facility fails to do so,
interim status will terminate on that
date.
  Completion of final permit application
will require individual facilities to
ttevttlop and compile information on
their on-sfte waste management
operations Including, but not limited to
Ina following activities: ground-water
monitoring (If wa&te management on
land is involved); manifest systems,
racordkocping, and reporting? closure,
and possibly, post-closure requirements;
and financial responsibility
requirements. The permit applications
may also require development of
engineering plans to upgrade existing
facilities. In addition, many of these
facilities will, in the future, be subject to
land disposal restrictions (LDR)
standards. As explained on September
1, EPA considers wastes which would
be brought under subtitle C regulation
by today's proposal to be "newly
identified** wastes for purposes of
establishing LDR standards under
section 3004(g)(4) of RCRA. (54 FR
M024). Under EPA regulations, LDR
standards must require treatment of the
affected wastes to a level or by a
method that reflects the use of Best
Demonstrated Available Technology
(BOAT) before the wastes can be
disposed on the land. Thus, one future
implication of today's proposed rule
fund the eventual final rule) will be the
ban on land disposal of these wastes
unless they are appropriately treated
prior to such disposal. EPA will further
address LDR standards for non-Bevill
mineral processing wastes within the
context of the upcoming "Third Third"
proposal.
  All existing hazardous waste
management facilities (as defined in 40
CFR 270.2) that treat, store, or dispose of
hazardous wastes covered by today's
proposed rule, and that are currently
operating pursuant to interim status
under section 3005(e) of RCRA, must file
with EPA an amended part A permit
application within six months of the
publication of the final rule, in
accordance with § 270.72{a).
  Under current regulations, a
hazardous waste management facility
that has received a permit pursuant to
Section 3005 may not treat, store, or
dispose of the wastes removed from
                          temporary exclusion by today's
                          proposed rule and which are
                          characteristically hazardous under 40
                          CFR part 261, subpart C when the final
                          rule becomes effective until a permit
                          modification allowing such activity has
                          occurred in accordance with § 270.42.
                          Consequently, owners and operators of
                          such facilities will want to file any
                          necessary applications with EPA well
                          before the effective date of the final rule.
                          EPA has recently amended its permit
                          modification procedures for newly listed
                          or identified wastes. (See 40 CFR
                          270.42(g).) For more details on the permit
                          modification procedures, see 53 FR
                          37912, September 28,1988.

                          2. Interim Status and Permit
                          Modifications in Authorized States
                            Until the state is authorized to
                          regulate  the wastes excluded from •
                          temporary exclusion by today's
                          proposed rule and which are hazardous
                          under 40 CFR part 261, part C, no permit
                          requirments apply and facilities lacking
                          a permit need not seek interim status.
                          Any facility treating, storing, or
                          disposing of these wastes on the
                          effective date of authorization of the
                          state to regulate these wastes under
                          RCRA may qualify for interim status
                          under applicable state law. Note  that in,
                          order to be no less stringent than the
                          Federal program, the state "in
                          existence" date for determining interim
                          status eligibility may not be later than
                          the effective date of EPA's authorization
                          of the state to regulate these wastes.
                          These facilities must provide the
                          required 3010 notification within 90 days
                          of publication of the final Federal rule as
                          described above and must also provide
                          the state's equivalent of a part A permit
                          application as required by authorized
                          state law.
                            Finally, RCRA section 3005(e) (interim
                          status) or any authorized state analog
                          will apply to  waste management
                          facilities qualifying for state interim
                          status. For those facilities managing
                          wastes under an existing state RCRA
                          permit, state  permit modification
                          procedures will apply.
                          VII. Effect on State Authorizations
                            This proposed rule will not be
                          effective in RCRA authorized states
                          until the  state program amendments are
                          effective, because its requirements are
                          not being Imposed pursuant to the
                          Hazardous and Solid Waste
                          Amendments of 1984. Thus, this removal
                          from temporary exclusion will be
                          applicable six months after publication
                          of the final rule only in those few states
                          that do not have final  authorization to
                          operate their own hazardous waste
                          programs in lieu of the Federal program.
In authorized slates, the reinterpretation
of the regulation of non-excluded
processing wastes will not be applicable
until the state revises its program to
adopt equivalent requirements under
state law and receives authorization for
these new requirements. (Of course, the
requirements will be applicable as state
law if the state law is effective prior to
authorization).
  Assuming that EPA makes final the
scope of the Bevill exclusion by January
15,1990, as planned, states that have
final authorization would be required
(40 CFR 271.21{e)) to revise their
programs to adopt equivalent standards
regulating non-Bevill mineral processing
wastes that exhibit hazardous
characteristics as hazardous by July 1,
1991 if only regulatory changes are
necessary, or by July 1,1992 if statutory
changes are necessary.  These deadlines
can be extended by up to six months
(i.e., until January 1,1992 and January 1,
1993, respectively) in exceptional cases
(40 CFR 271.21(e)(3)). Once EPA
approves the revision, the state
requirements become RCRA Subtitle C
requirements in that state. States are not
authorized to regulate any wastes
subject to today's proposal until EPA
approves their regulations. Of course,
states with existing standards that
address these wastes may continue to
administer and enforce  their regulations
as a matter of state law.
  Currently unauthorized states that
submit an official application for final
authorization less than  12 months after
the effective date of the final rule may
be approved without including an
equivalent provision (i.e., to address
non-Bevill mineral processing wastes) in
the application. However, once
authorized, a state must revise its
program to include an equivalent
provision according to the requirements
and deadlines provided at 40 CFR
271.21(e).
VIII. Economic Impact Screening
Analysis Pursuant to Executive Order
12291
  Sections 2 and 3 of Executive Order
12291 (46 FR 13193) require that a
regulatory agency determine whether a
new regulation will be "major" and, if
so, that a Regulatory Impact Analysis
(RIA) be conducted. A major rule is
defined as a regulation  that is likely to
result in one or more of the following
impacts:
  (1) An annual effect on the economy
of $100 million or more;
  (2) A major increase hi costs or prices
for consumers, individuals, industries,
Federal, State, and local government
agencies, or geographic regions; or

  (3) Significant adverse effects on
competition, employment, investment,
productivity, innovation, or on the    :

enterprises to compete with foreign-
based enterprises in domestic or export
markets.
  When final, today's proposed rule will
complete the Agency's revised
interpretation of the Bevill Mining
Waste Exclusion for mineral processing
wastes, previously proposed under
Court-ordered deadline on April 17,1989
(54 FR 15345). The first part of this
reinterpretation, dealing with the vast •
majority of individual small volume
waste streams, was made final on
September 1,1989. The preamble to the
September rule presented the results of
the Agency's economic impact screening
analysis, covering scores of small
volume mineral processing wastes, and
examining cost impacts associated with
39 potentially hazardous small volume
wastes in detail. This analysis indicated
a total annual compliance  cost for
subtitle C waste management of about
$54 million. As indicated in Section V of
this preamble, today's proposed rule
would remove seven additional
processing wastes from the Bevill
exclusion and subject them to coverage
under existing subtitle C regulations if
they exhibit hazardous characteristics.
  Consistent with Executive Order
12291, the Agency has completed a
preliminary economic impact screening
analysis for the seven mineral
processing wastes proposed for removal
from the Bevill exclusion in today's
proposed rule. Results of thijs analysis
suggest that five of the seven waste
streams are likely to exhibit hazardous
characteristics at some or  all of the
facilities that generate them, and that
nine minerals processing facilities in
five different commodity sectors are
likely to incur compliance  costs if the
Bevill status of these wastes is
permanently removed. The Agency,
estimates that total annual compliance
costs will be on the order of $5 million,
and.would thus not indicate that today's
proposal is a "major rule"  according to
the-first criterion  of E.O.12291.
   In addition, for reasons,  set out below,
EPA does not predict a substantial
increase in costs  or prices for consumers
or a significant effect on international
trade or employment in connection with
today's proposal. One or two individual
mineral processing facilities may
experience moderate compliance costs
which could affect their ability to   '  '
compete in their respective commodity
sectors. On balance, the Agency does
not believe that today's proposed rule
constitutes a major rule as defined by
E.0.12291.
  The following paragraphs of this
section present the Agency's economic
impact screening approach,
assumptions, and results in more detail.

A. Approach
  The Agency's screening analysis was
based on a modification of the
procedure used to develop the cost and
economic impacts of the September 1,
1989 final rule, details of which are.
provided in the technical background
document for that rule.3 The major
differences between the two analyses
are that in this instance, EPA conducted
facility-specific, rather than sector-wide
analyses, and used newly available
waste characteristics, generation, and
management data collected through the
Agency's recent sampling effort and
industry survey. These new data
allowed EPA to characterize waste
streams and current and prospective
management trains much more
accurately for the seven wastes studied
for today's proposed rule.
  Because many of these site-specific
data have been designated Confidential
Business Information (CBI) by company
respondents, EPA has not provided
information in this preamble or in the
supporting technical background
document * on facility-specific waste  .
generation rates or management
practice assumptions, in order to
prevent unauthorized release of
company-specific information. For
presentation purposes, however, the
Agency has developed proxies for some
of the confidential information (e.g.,
commodity production rates) from
published sources,5 and has used and
reported this information in the  analysis
presented below.
  Waste characteristics for the seven
wastes were ascribed based on EPA
waste sampling data. In contras.t to the
criteria and test procedures used to
determine whether the wastes are "low
hazard" for purposes of today's
proposal, the approach used here
employed EP toxicity test results and
standard hazardous waste characteristic
tests (e.g., corrosivity limits of pH
between 2.0 and 12.5), because these are
the tests and regulatory levels that will

 be used to determine whether wastes
 will be regulated under Subtitle C after
 removal from the Bevill exclusion.,
 Although wastes were not sampled at
 every facility generating each waste
 type, EPA used the conservation
 assumption that if a  waste type
 exhibited one or more hazardous
 characteristics at one sample facility,
 then it would exhibit the same
 characteristics (i.e., pass or fail) at all
 facilities generating  the same waste,
 unless there was specific sampling
 evidence  to the contrary. Therefore, EPA
 may have overestimated costs and
 impacts for some facilities and sectors
 for which sampling was not
 comprehensive for all facilities.
   Of the seven waste streams reviewed,
 the preliminary screening assessment
 suggests that two—process wastewater
 from coal gasification and sulfate
 process waste solids from titanium
 dioxide production—are not likely to
 test hazardous under current
 characteristic test procedures.
 Accordingly, EPA has assumed in the
 economic screening  analysis that the
 facilities generating  these two wastes
 will experience no compliance cost
 impacts associated with potential
 subtitle C regulation of these wastes.
 The remaining five waste streams were
 considered hazardous at all facilities, for
 the characteristics specified, as follows:
   •  Chromite roast/leach ore residue—
 EP toxic for chromium.
   •  Element phosphorus off-gas solids
 (from wet collection)—EP toxic for
 cadmium.
   •  Hydrofluoric acid process
 wastewater—Corrosive.
   •  Primary lead process wastewater—
 EP toxic for arsenic, cadmium, and lead,
 corrosive.
   •-Titanium dioxide sulfate process
 waste acids—EP toxic for chromium,
 corrosive.
   These commodity sectors and wastes
 were then further analyzed in terms of
 current (baseline) management
 practices.
   As in the previous screening analysis
 for the September rule, the Agency
 developed baseline  and subtitle C
' treatment scenarios for the wastes to be
 withdrawn from the Bevill exclusion and
 estimated the incremental costs incurred
 by each sector in treating the wastes as
 hazardous under RCRA. In contrast to
 the previous analysis, however, EPA
 simulated costs for baseline
 management practices on a site-specific
 basis using the actual data provided for
 each of the 13 potentially affected
 facilities  in the five  sectors studied.
 Subtitle C management practices were
 developed as before, using knowledge of

-------
 89314       Federal Register / Vol. 54, No. 184 / Monday. September 25, 1989  /  Proposed Rules
 subtitle C requirements and best
 engineering judgment
   EPA determined that five of the 13
 facilities analyzed on the basis of
 company-provided data are currently
 managing hazardous wastes in
 compliance with current subtitle C
 requirements, and thus might not incur
 additional costs if this rule is
 promulgated in its present form. For
 example, if an affected facDity already
 has one or more appropriate waste
 management units with approved
 subtitle C permits and sufficient
 capacity to manage a newly non-Bevill
 characteristic waste, then the regulatory
 compliance costs associated with
 removing the waste from the Bevill
 exclusion would be a small fraction of
 what they would be otherwise, and
 would consist primarily of incremental
 operating and maintenance fas opposed
 to capital construction and closure)
 coats. The data used to establish these
 bnicline waste management
 assumptions were obtained from
 responses to EPA's 1987-88 National
 Survey of Hazardous Waste Treatment,
 Storage, Disposal, and Recycling
 Facilities (TSDR Survey], The methods
 used to organize and manipulate these
 data are described in a technical
 background document to the September
 1 final rule.*
  Other information sources also
 indicate that compliance costs
 associated with this rule will be lower
 than would be predicted using standard
 waste management assumptions. Data
 from the National Survey of Solid
 Wastes from Mineral Processing
 Facilities indicate that current practice
 for managing many of the wastes
{particularly the wastewaters) proposed

 for removal in today's NPRM includes
 treatment in a wastewater treatment
 plant, direct discharge via NPDES
 permit provisions, and/or recycling to
 the process generating the waste in
 question. EPA has reviewed this
 information, and used it to develop
 baseline and subtitle C compliance
 scenarios for this analysis. As a result,
 estimated compliance costs at several of
 the facilities affected by today's
 proposal are zero, i.e., removal of the
 waste from Bevill will impose no
 operational or economic impacts.
 B. Aggregate and Sector Compliance
 Costs
  The impact screening analysis
 projects that nine facilities in five
 different mineral processing commodity
 sectors will be affected directly by
 today's proposed rule. Another four
 facilities, one each in the chromite and
 titanium dioxide sectors, and two in the
 lead sector, are believed to be
 unaffected by virtue of already
 incorporating Subtitle C (or equivalent
 NPDES wastewater treatment) practices
 in their current waste management
 systems. In aggregate, the total  impact of
 today's rule is  estimated to be about $5.2
 million per year.
  EPA cost estimates for individual
 facilities are presented by sector in
 Table 4. Two sectors, titanium dioxide
 and chromite, are expected to
 experience aggregate sector impacts in
 excess of $1 million annually. Within
 each of these two sectors, all of the cost
 impacts are predicted to fall on one of
 the two facilities, with the other
 producer's waste management costs
 being unaffected by removal from the
 Bevill exclusion. The hydrofluoric acid
 manufacturers (Allied Signal and
Pennwalt) would experience cost
 increases of about $500,000 and $200,000,
respectively. The primary lead
producers, Asarco and Doe Run, would
 experience compliance cost impacts of
 $41,000 and $235,000, respectively.
 Estimated cost impacts for individual
 primary lead facilities range from zero
 to $201,000 annually, depending on
 current management practices and
 plant-specific waste characteristics. The
 two (of five) elemental phosphorus
 plants that are expected to experience
 impacts have total estimated
 incremental costs of $179,000 annually,
 with the vast majority ($173,000)
 imposed on the facility owned by
 Occidental Chemical Corporation.

  At four facilities, estimated
 compliance costs are zero, i.e., removal
 of the facility's candidate special waste
 from the Bevill exclusion, will impose no
 cost or economic impacts. This is
 primarily due to the current
 management practices being employed
 at these four facilities. The unaffected
 TiO2 facility (Kemira) is a fully
 permitted RCRA subtitle C management
 facility; examination of data from EPA's
 TSDR survey reveals that the permits
 and waste management units necessary
 to handle the newly non-Bevill waste as
 a regulated hazardous waste are already
 in place. At the unaffected chromite
 facility (American Chrome and
 Chemical), EPA survey and sampling  •
 data indicate that the waste goes
 directly to a wastewater treatment
 system (exempt from subtitle C), which
renders the waste material (both solids
and effluent) non-hazardous. Therefore,
the facility can continue to manage the
waste under current practice,
irrespective of Bevill status. Similar
considerations indicate that two of
Asarco's primary lead facilities (Omaha
and Glover) would also be unaffected
by today's proposed rule (waste
generation and management data have.
been designated CBI by Asarco).

assumed that the DuPont facility not experience impacts from this rule.

C. Economic Impacts
  EPA's screening-level analysis of
economic impact compared the
magnitude of compliance costs for each
affected facility to the estimated value
of shipments. This ratio provides a first
approximation of the extent to which -
the profitability of firms, or,
alternatively, commodity prices, or other
measures of national impact may be
adversely affected by the imposition of
regulatory compliance costs.
1. Impacts on Commodity Sectors

  Economic impacts, expressed as  the
ratio of annual compliance costs to
annual value of shipments, are
displayed in Table 5. Sectors or facilities
with ratios above one percent were
considered vulnerable to moderate to
significant financial impacts arid were
evaluated in more detail in terms of
market and industry factors that might
affect the ultimate incidence and impact
of the costs.                         -
  As seen in Table 5, only two facilities
(one each in the titanium dioxide
(sulfate), and sodium chromate/
bichromate sectors) are predicted to
experience impacts* above the one
percent level, both at around 1.5 percent.
This level of impact is regarded as
moderate. The two elemental
phosphorus (FMC and Occidental),
primary lead (Asarco and Doe Run), and
hydrofluoric acid producers (Allied-
Signal and Pennwalt) examined in this
study are expected to experience only
minor economic impacts. Obviously,
firms and facilities already in
compliance and with compliance costs.
of zero (i.e., Kemira, American Chrome
and Chemical, and Asarco) will not
experience any economic impacts
associated with this rule.
  To further explore the economic  :
impact of today's proposal, EPA has
examined some of the factors that affect
the ability of affected firms to pass
through prospective compliance costs to
product consumers in the form of higher
prices. These factors include absolute
price levels, major end users of the
mineral commodity, competition from
imports and substitutes, secondary
production, and flexibility in other
production cost factors. These are
discussed for each of the two affected
sectors in the paragraphs below.
  a. Titanium dioxide. Titanium dioxide
is used in pigments for paints and
surface coatings, paper manufacturing,
and plastics. Half of titanium dioxide
production is consumed in pigments,
where its competitive position is strong.
Demand for high-quality paper also
favors titanium dioxide.
  The domestic industry supplies most
of the titanium dioxide used in the U.S.,
with imports exceeding exports by'only
a moderate degree. As a result, titanium
dioxide is in a relatively strong market
position. Producers using the sulfate
process, however, are in a minority and
account for only one eighth of domestic
production. It is not likely that the one
affected producer could establish a
premium for its product and would
therefore be limited in the extent to
which it could recover cost increases.
  b. Sodium chromate and bichromate,
Sodium chromate and bichromate are
used in a number of applications,
including chrome pigments for paints.
Derivative chrome pigments have
excellent performance characteristics
and have experienced gains in certain
applications, such as traffic paints and -
automotive coatings. The U.S. is a net
exporter of sodium chromate and
bichromate.
  Given the low level of import
competition and the small number of
producers in the domestic industry, the
one affected producer is apt to have a
reasonably good prospect of recovering
production cost increases.

If so, regulatory alternatives that
eliminate or mitigate the impacts must
he considered.
  In the preamble to the September final
rule, the Agency presented a description
of and the results from a comprehensive
screening analysis to determine the
potential for significant small business
impacts imposed by the reinterpretation
of the Mining Waste Exclusion. The
analysis conducted for today's proposal
was conducted using identical
procedures. These are outlined very
briefly below and are described mqre
fully in the'technical background
document to the September final rule.
  The Agency has concluded that
today's  proposed rule will not have a
significant adverse impact on a
substantial number of small mineral
processing companies, because there are
no small businesses in the sectors that
are expected to experience impacts from
today's  proposed rule.
A. Definition of Affected Small Entities
  Today's proposal would impose
impacts only on the facilities in the five
commodity sectors that generate wastes
that would be removed from the Bevill
exclusion and that could fail any of the
  Agency's tests for hazardous waste
  characteristics. Based upon the
  information contained in the responses
  to the industry survey and EPA waste
  sampling results, the five mineral
  commodity sectors and nine facilities
  most likely to face subtitle C compliance
  costs have been identified in section
  VIII of this preamble.
    For purposes of defining "small
  business" firms, EPA has again relied on
  the standard definitions of the Small
  Business Administration (SBA) as
:  published at 13 CFR ch. 1, part 121. For
  the industries in question, SBA employs
  a basic employment-based definition,
  with the small business cut-off value  for
  total company employment ranging
  between 500 and 1,000 employees,
  depending upon the specific industry in
  question.
    For the affected mineral processing
  facilities identified!above in section VIII,
  EPA conducted a comprehensive RFA
•  business ownership screening analysis
  for those mineral commodity sectors
  estimated to incur economic impacts
  associated with today's proposed rule.
  All potentially affected plants and
  businesses were examined individually.
  Facility location and ownership
information was obtained as in the
previous analysis  in support of the
September 1 final  rule (see 54 FR 36592).
Data on the employment size of affected
firms were obtained from published
sources [e.g., Standard & Poors, Dun &
Bradstreet). The Agency then compared
reported company employment to the
Small Business Administration's (SBA's)
definition of a small business for each
sector's SIC code  to determine the
number of small businesses, if any, in
that sector. SBA defines small
•businesses as less than 1000 employees
or less than 750 employees for most of
the SIC codes.      .

B. Results                    .

  As shown in table 7, EPA believes
that all of the firms that might be
affected by .today's proposal are large
businesses, according to the SBA's
company size criterion. Accordingly, the
Agency concludes that there will not be
a significant (or, in fact, any) adverse
impact on a substantial number of small
mineral processing companies as a
result of this rulemaking.
