                                EXECUTIVE SUMMARY
      REGULATORY IMPACT ANALYSIS OF LAND DISPOSAL RESTRICTIONS FOR
                 NEWLY IDENTIFIED WASTES AND HAZARDOUS SOIL

       This report, a regulatory impact analysis, estimates the costs, economic impacts,, and
benefits due to the Land Disposal Restrictions (LDRs) for newly identified wastes and hazardous
soil.  The rule has been developed by EPA as part of its legislative mandate to restrict the land
disposal of hazardous wastes where necessary to protect human health and the environment.

ES.l   WASTES AFFECTED BY THE RULE
       The rule would set land disposal treatment standards for the following wastes:
       •     organic toxicity characteristic wastes (RCRA waste codes D018 to D043);
       •     organic toxicity characteristic (D018 to D043)  hazardous soil;
       •     organic toxicity characteristic (D018 to D043)  hazardous debris;
       •     characteristic pesticide wastes that were not previously hazardous using the EP
             leaching procedure (D012 to D017);
       •     coke  production wastes (K141, K142, K143, K144, K145, K147, and K148); and
       •     chlorotoluene wastes (K149, K150, and K151).

       In addition, the rule establish universal treatment standards (UTS). These standards will
update nearly all current concentration-based treatment standards with constituent-specific UTS
concentrations.  The quantity of wastes affected by the rule are shown in Exhibit ES-1.

ES.2   COST  AND ECONOMIC IMPACTS OF RESTRICTING THE LAND DISPOSAL OF PHASE D
       WASTES
       Using data available from EPA's  1992 survey of facilities  that manage TC wastes, EPA
was able to develop  facility-specific cost estimates for the post-regulatory treatment of these
wastes  EPA examined the data for each wastestream and assigned an appropriate treatment
technology for the post-regulatory alternatives.  In addition to organic TC wastes, the Phase n
rule affects coke by-product and chlorotoluene wastes, and EPA conducted a facility-specific cost
analysis for these affected waste streams.

            rates, which EPA assumes are indicative of iteady itate generation.                       .         .

          b/ As part of toe Advance Notice of Rulemaking for the PbaK D LDRs, EPA requeued data on the D012 lo D017 pesticides that exhibit the
          ~ toaciry cbancterbtic using the Tosojry Cbaracterislic Leaching Procedure (TCLP) but not the Emotion Procedure (EP). EPA received
            no data in response to this request, and it n assuming that this wast* volume will be negligible.
          c/ Although there are large wastewater and nonwasuwater volumes of coke by-productt, none of these volumes is "p**"^ to be bmd
          " disposed. On-site processes coostioiting trauncnt (it, coking) are Ibe man economical mamigement method for these wastes and are
            currently widely practiced among coke and tar refining facilities.

          d/ The affected universe b defined here as the universe of all wastes to which the UTS apply that are estimated to have cost impacts from the
          ~ change in treatment levels.

          tt In addition, up to 7 minion tons of an previously regulated waste could be affected by the streamlining effect of the VIS. See disamton in •
            Chapter 3. _ ' _ ' _

Executive Summary                                                                  Page ES-3
       ES.2.1 Cost of the Rule
       Exhibit ES-2 summarizes the results of the cost analysis. In total, the Phase IILDR rule
would have an incremental annual cost of $191 to $219 million (representing accounting or not
accounting for waste minimization savings).  Sixty-seven percent of this cost would be for the
treatment of organic TC nonwastewater wastes,  and 16 percent and 17 percent would be for the
treatment of organic TC hazardous soil and debris. In addition, there may be a potential savings
of $1 million, associated with previously regulated waste affected by UTS and modifications to the
recycling definition. The cost savings associated with waste minimization is estimated to be $25
million. Finally, the streamlining effect of UTS  on the treatment of previously regulated waste
presents a savings ranging from $0 to $55 million for incinerable wastes and  $0 to $41 million for
wastes suitable for physical/chemical treatment.

       ES.2.2 Economic Impacts of the Rule
       For the 14 captive (i.e., non-commercial) facilities in the TC capacity database, only one
company would experience serious economic impacts when considering the ratio of incremental
compliance cost to cost of operations.
       Since no costs are associated with the treatment standards for coke by-products, no
economic impacts are expected. Economic impacts for facilities that generate chlorinated toluene
wastes are such that no facilities are expected to experience significant impacts as a result of the
rule.

ES.3   BENEFITS OF RESTRICTING THE LAND DISPOSAL OF PHASE n WASTES
       EPA's analysis of the benefits of the Phase II LDRs  addresses only TC wastes.  These
wastes dominate the  other newly identified wastestreams covered  by the Phase II LDRs  in terms
of volume and  costs.. EPA  evaluated  three types of benefits  for this RIA:  reduction  in human
health  risks via the ground-water  pathway, reduction in human health  risks via the air pathway,
and positive effects on the value of properties near waste management  facilities.

       ES.3.1  Human Health Risk Reduction — Ground-Water Pathway
       EPA  analyzed baseline human health risks, i.e.,risks posed by untreated  TC wastes
managed in Subtitle C landfills as well as post-regulatory risks. The difference in risks between
the baseline and the  post-regulatory  condition is a measure of the benefits of the rule.
       Exhibit ES-3  presents the estimates of the baseline and post-regulatory individual cancer
risk across all facilities.  The results are  presented in terms of a cumulative frequency distribution
indicating the. percentile level  associated with an individual risk level across all facilities.  As the
exhibit shows, the high-end baseline  risk estimate  is between one  and  two orders of magnitude
higher than the central tendency estimate across the distribution.  About ten  percent  of the
individual risk values indicate baseline lifetime excess individual cancer risk exceeding 10"6 under
high-end assumptions, with almost five percent  exceeding 10"4.  About six percent  of the
individual risk values exceed 10"6 in the baseline  using central tendency  assumptions,  including
about two percent which exceed 10"4. In the post-regulatory case, about five percent of the
individual risk indicate excess cancer risks above  10"6, and  about  one percent  exceed  10"4.
       EPA's modeling  also indicated estimated  that non-caner effects were  low.  Using central
tendency assumptions, the 99th percentile baseline exposure level is less than the reference  dose.
Under high-end assumptions, about two percent of the  distribution  exceeds a hazard  index of
unity, indicating the potential for adverse non-cancer effects.  Post-regulatory non-cancer risk,
however, is insignificant.
       The central tendency  estimate of baseline population cancer risk is on the order  of 0.24
cases per year.  The post-regulatory population cancer risk is about  0.02 cases per year.  In other
words, the rule reduces 0.22 cases per year, or 92 percent of the baseline cancer cases.

        ES.3.2 Human Health Risk Reduction—AirPathway
        Constituents  contained in TC waste, soil, and debris  may be emitted to air through
volatilization and dust entrainment.  Reducing the concentrations  of TC constituents through the
Phase  II LDR  treatment  standards significantly reduces the  potential  for air emissions, and the
risks posed  by those  air emissions.                                                   .
        In the  baseline, 26 of the  35 modeled facilities (74 percent)  have individual  cancer risks
exceeding  10"6 at the high-end individual location:  16 have  risks between 10"6 and  10"4, and  10
facilities have  risks greater than 10"4.  The  highest value is 5 x 10"3.  For the high-end individual
location, the non-cancer  risk ratio exceeds  one at only one facility.  Note that these high-end
values represent  risks to  a hypothetical,  and not an actual, individual.
        The final regulation effectively reduces individual cancer risk.  At the  high-end individual
location, eight facilities have risks exceeding 10"6; the highest individual  risk is 8 x 10"6.  Doses  of
all non-carcinogens are well below reference  doses.
        Exhibit ES-4 presents  population risks. The central  tendency estimate of baseline
population cancer risk is on the order of 0.037 cases per year. The post-regulatory  population
          ^
cancer risk is about 0.0002 cases per year.  In other words, the rule reduces 0.036 cases per year,
or 99 percent  of the baseline cancer cases.

        ES.3.3 Effects on Property Values
        Treating  organic  TC wastes would allow them to be  disposed of  in Subtitle D (i.e., non-
hazardous)  waste facilities rather  than in Subtitle C (i.e, hazardous)  waste facilities.  To estimate
the potential benefit  resulting from changes in property values that  would occur if Subtitle C
facilities were  replaced by Subtitle D facilities, EPA modified a hedonic  pricing/land value study
and applied it to the universe of affected facilities. The premise of hedonic property value
analysis is that housing prices are determined by a range of  attributes of the house,  its site, and its
neighborhood.   If one attribute  included in the analysis is  an environmental  characteristic, the
effect  of that  characteristic  on price can be used to estimate the benefits from changes in the
level of that characteristic  (e.g. a  change in the distance to a waste  site).
        For the purpose  of estimation, EPA assumed that  each of the  30 captive non-CBI Subtitle
C sites would be converted  to or  replaced  with a Subtitle D facility under the LDRs. Using U.S.
Census Bureau data, EPA estimated  the value and density of owner-occupied houses in the

ES.4  LIMITATIONS OF THE ANALYSIS
       The analysis has  several limitations in scope and methodology.  EPA is not considering the
impacts of the rule with  regard to lab packs or newly regulated characteristic pesticide waste, as
standards  for these wastes are being changed slightly.  Also, EPA  is not considering the  effects
that  may be associated with universal standards for all listed wastes or recycling provisions being
promulgated.                                    .      '         .        ~
       More important,  the cost, economic impacts, and benefits  analyses have limitations
resulting from both methodology  and available data.  Some limitations overestimate  costs and
benefits, others underestimate values, and  some limitations introduce uncertainty where  the
direction of bias is unknown.  Sections 3.3,4.3, and 5.4 of this document detail the limitations of
the analysis.

(Section 3QQ4(g)).1  This section of RCRA specifies a schedule for the restriction of certain land
disposal practices of hazardous wastes and directs the Environmental Protection Agency (EPA) to
develop a regulatory framework for implementing the land disposal restrictions program.
       This report, a regulatory impact analysis, estimates the costs, economic impacts,  and
benefits which are due to the Land Disposal Restrictions (LDRs) for newly identified wastes.
This document fulfills the requirements of Executive Order No. 12866. This executive order
requires EPA to determine whether the regulatory action  is "significant" and therefore subject to
OMB review and the requirements of the Executive Order.  This document also fulfills the
requirements of the Regulatory Flexibility Act (at 5 U.S.C. 601  et seq.V which requires  federal
agencies to assess the effects of regulations  on small entities and to examine regulatory
alternatives that may bring about any adverse economic effects on these small entities.

1.1    LEGISLATIVE MANDATE AND EPA ACTIONS IN RESPONSE TO THE LAND DISPOSAL
       RESTRICTION PROVISIONS OF HSWA
       Through HSWA, Congress directed  EPA to restrict the continued land disposal of RCRA
hazardous waste and to develop a regulatory framework for implementing the land disposal
restrictions by specified dates.  As part of this statutory direction, HSWA authorized EPA to
promulgate regulations restricting the land disposal of hazardous wastes where necessary to
protect human health and the environment.
       In addition,  HSWA directed EPA to promulgate treatment standards that would
substantially diminish the toxicity of hazardous wastes or reduce the likelihood of migration of
hazardous constituents from the waste (RCRA Section 3004(m)). Treatment standards may be
   1 As defined in the statute and regulatory framework, land disposal includes, but is not limited to, disposal in
landfills, surface impoundments, land treatment facilities, waste piles, salt dome formations, salt bed formations,
underground mines or caves, as well as treatment or storage in surface impoundments. Underground injection, a
regulated form of land disposal, is addressed in a separate RIA which accompanies the proposed rule.

technology-based (i.e., specified treatment methods that must be employed before land disposal)
or concentration-based (i.e., specified concentration levels that must be attained before land
                              i
disposal). EPA's preference, whenever possible, is to establish concentration-based treatment
standards, because this allows the regulated community greater flexibility in complying with the
land disposal restrictions.
       EPA's progress has been in accordance with the schedule set forth in HSWA. As
required, EPA submitted to Congress a schedule for promulgating land disposal restrictions
regulations for scheduled wastes on May 28, 1986 (51 FR 19300).
       On November 7,1986 (51 FR 40572), EPA promulgated the land disposal restrictions rule
that is referred to as the "framework" rule.  This rule set forth much of EPA's land disposal
restriction policy as well as treatment standards and effective dates for spent solvents and dioxin-
containing hazardous wastes.
       On July 8, 1987 (52 FR 25760), EPA promulgated the "California List" land disposal
restrictions. In this rule, treatment standards were established for liquid and non-liquid hazardous
wastes containing halogenated organic compounds (HOCs), and for liquid hazardous waste
containing polychlorinated biphenyls (PCBs).  Also, the statutory prohibitions on the land disposaT
of corrosive wastes and dilute HOC wastewaters were codified, and the hard hammer provisions
took effect for free cyanides and California  List metals. (The hard hammer provisions in RCRA
Section 3004 stipulated that land disposal of specified wastes would be banned  altogether if EPA
did not promulgate treatment standards within given time periods.)
       EPA promulgated the First Third scheduled wastes rule on August 18, 1988 (53 FR
31138).  Treatment standards  and effective dates for relatively high volume, intrinsically hazardous
wastes were established in that rule. EPA promulgated the Second Third scheduled wastes rule
on June 23, 1989 (54 FR 26594) and the Third Third scheduled wastes rule on June 1,1990 (55
FR 22520).
       In addition to the above rules, for which specific deadlines were enacted in HSWA,
Congress directed EPA to promulgate standards for all newly listed and identified wastes (i.e.,
wastes brought into the RCRA system after the enactment of HSWA in 1984)  six months after
promulgating listing rules.  These newly identified and listed wastes are being addressed in  phases.
The first phase, which addressed a group of newly identified wastes and all hazardous debris, was

promulgated on August 18, 1992 (57 FR 37194). This RIA document accompanies the rule for
the second phase, which covers a different set of newly identified wastes, including organic toxicity
characteristic (TC) wastes, characteristic pesticide wastes that were not previously hazardous using
the EP leaching procedure, coke production or by-product wastes, and chlorotoluene waste.  The
Phase II rule has been under development for several years, and the final rule reflects EPA's
consideration of comments received on the Phase n proposed rule (58 FR 48092).
       On September 25, 1992, the United States Court of Appeals for the District of Columbia
Circuit ruled on the various petitions for review filed against EPA regarding the Third Third
rule.2 The principal holdings of the case with respect to characteristic wastes, under EPA's
reading of the opinion, are that (1) EPA may require treatment under RCRA section 3004(m) to
more stringent levels than those at which wastes are identified as hazardous; (2) section 3004(m)
requires that treatment standards address both short-term and long-term potential hazards posed
by hazardous wastes, and consequently must result in the destruction and removal of hazardous
constituents as well as removal of the characteristic property; and (3) situations where
characteristic hazardous wastes are diluted, lose their characteristic^), and are then managed in
centralized wastewater management land disposal units (e.g., surface impoundments or injection
wells) are legal only if it can be demonstrated that hazardous constituents are reduced or
destroyed to the same extent they would be pursuant to otherwise applicable RCRA treatment
standards.
       EPA is taking the position that to minimize the short- and long-term potential hazardous
posed by hazardous waste, it is necessary to promulgate treatment standards  for the underlying
constituents (i.e., non-TC code carrying constituents) likely to be present in characteristic wastes.
Not all characteristic wastes will be affected by the Phase n rule, however.  EPA will address
characteristic wastes managed in Clean Water Act (CWA) systems, CWA-equivalent systems, or
Class I Safe Drinking Water Act (SDWA) injection wells in a later rulemaking.

                      CHARACTERIZATION OF AFFECTED WASTES

       To assess the costs and benefits of setting treatment standards for the waste and
contaminated soil addressed in the Phase II LDR final rule, EPA first estimated the quantity of
affected waste and soil. In general, the waste and soil affected by the land disposal restrictions
are those currently disposed of in landfills, surface impoundments, or land treatment facilities;
they may  also be stored or treated in waste piles. The Phase II rule also will affect some wastes   •
currently  regulated under the LDR program because of new regulatory modifications.
       EPA discusses the waste affected by the Phase II LDR rule in two parts of this chapter.
In Section 2.1, we discuss waste newly affected  by the Phase II rule.  In  Section 2.2, the Agency
discusses waste already regulated by the LDR program that will be affected by the two changes in
the regulations: the promulgation of universal treatment standards (UTS), and a modification  of
the definition of recycled materials.  Exhibit 2-1 summarizes the  quantities of all wastes affected
by the Phase II LDR rule. In brief, the rule will bring into the LDR program an annual quantity
of nearly  300,000 tons of waste, and it will change existing requirements for roughly 11,000 tons
being generated annually.

2.1    AFFECTED WASTES NEWLY REGULATED BY THE LDRs
       The rule will set land disposal treatment standards for the following newly identified and
listed wastes:

       •      organic toxicity characteristic wastes  (RCRA waste codes D018 to D043);1

       •      organic toxicity characteristic (D018  to D043) hazardous  soil;

       •      organic toxicity characteristic (D018  to D043) hazardous  debris;
   'The Phase II LDR rule covers organic TC wastewaters as.well as organic TC nonwastewaters, soil, and debris.
However, it excludes from its scope wastes managed in CWA. or UlC-regulated units (LDR standards for these wastes
will be included in a future rulemaking). Because virtually all wastewaters are managed in CWA or UlC-regulated units,
EPA assumes wastewaters are affected by the Phase n rule.

          b/ As part of the Advance Notice of Rulemaking for the Phase II LDRi, EPA requested data on the D012 to D017 pesticides that exhibit the
            tozicity characteristic using the Toscity Characteristic Leaching Procedure (TCLP) but not the Extraction Procedure (EP). EPA received
            no data in response to this request, and it b assuming that this waste volume will be negligible.

       •      characteristic pesticide wastes that were not previously hazardous using the EP
              leaching procedure (D012 to D017);

       •      coke production wastes (K141, K142, K143, K144, K145, K147, and K148); and

       •      chlorotoluene wastes (K149, K150, and K151).

       2.1.1   Organic Toxicity Characteristic Wastes
       EPA added 26 waste codes representing organic contaminants (i.e., D018 to D043) to the
toxicity characteristic as part of the toxicity characteristics revisions rule (March 29, 1990, at
55 FR 11796).  The Phase II final rule sets treatment standards for wastes and soil that exhibit
the characteristic for these waste codes.  To gather information about the generation and
management practices of organic TC wastes, EPA conducted a census of facilities land disposing
these wastes (OMB Information Collection Request Number 1605).

       Design ofEPA's 1992 Survey of Organic Toxicitv Characteristic Wastes Managed in
       Land Disposal Units (TC Survey)
       In the spring of 1992, EPA conducted a  census of all facilities  that manage newly
identified TC organic wastes in land disposal units or dispose of these wastes in underground
injection wells.  This survey was an important source of information for the RIA; it is described in
detail in Appendix A, and summarized below.
       The primary purpose of the survey was to obtain  estimates of the quantities,
characteristics, and management practices of newly identified organic TC wastes (D018-D043) that
would be managed in land disposal units (i.e., landfills, land treatment units, surface
impoundments, waste piles and underground injection wells) from 1992 to 1995.  The survey
focused on waste disposal systems because the land disposal restrictions apply only to those wastes
destined for land disposal. The Agency understands that many TC wastes are currently treated
(e.g., incinerated) despite the absence of regulatory standards.
       For each facility, EPA requested wastestream specific data on  newly identified TC organic
wastes and information about on-site land disposal units and treatment and recovery systems.

Page 2-4                                                             Characterization of Wastes


       EPA identified the universe primarily based on those facilities which had submitted permit
modifications or received interim status for managing newly identified organic TC wastes (DO 18-
D043).  EPA used four major data sources to identify facilities suspected of managing these
wastes in land disposal units:

       •      National Survey of Hazardous Waste Treatment, Storage, Disposal, and Recycling
              Facilities (TSDR Survey);

       •      Resource Conservation and Recovery Information System (RCRIS);

       •      Compliance information compiled by EPA Regional Offices; and

       •      Underground injection well information compiled by the EPA Office of Water,
              Underground Injection  Control Branch (UICB).

       The TSDR survey was used to  identify the  type of land disposal units at TSDR facilitieB
RCRIS provided information on whether owner/operators had submitted a Part A or Part B
application for changes in management practices (i.e., because the facility was receiving newly
identified TC wastes as of September 5, 1991).  In  addition, OSW had obtained from each EPA
region a list of facilities that  had submitted Part A  applications or Part B modifications for the
generation or management of organic TC wastes.  Using this information EPA verified the data
provided by the TSDR Survey and RCRIS, and also identified 50 additional survey participants.
EPA identified the facilities disposing of newly identified TC wastes in underground injection
wells from information provided by UICB. Also, EPA assumed that many commercial facilities
would manage organic TC wastes; consequently, all commercial landfills and surface
impoundments were included as potential survey participants.
       EPA initially identified 400 facilities as potential survey participants. Each facility was first
called to verify that the facility was managing TC wastes in land disposal units.  Based upon this
screening, EPA identified 140 facilities that might manage organic TC wastes in land disposal
units. Of the 140 questionnaires mailed, 5 were not returned.  Forty-four facilities responded that

they do not land dispose TC wastes, and 91 facilities confirmed that they manage organic TC
wastes in land disposal units.  EPA compiled the data provided by these 91 facilities in a database
used for the RIA and capacity analyses for the Phase II LDR rule.  More information on the TC
Survey and the associated database used for analyses can be found in the background document
                                        	              O
on the capacity analysis for the Phase II LDRs Final Rule , located in the docket.

        Use of the TC Survey for this Analysis
        The survey requested information on all organic TC wastestreams, even those not affected
by the rule (e.g., wastewaters managed in UIC units).  For this analysis EPA has selectively used
the information developed from the TC Survey.  The Agency separated responses from facilities
with all organic TC wastes managed exclusively in CWA or UlC-permitted units as well as all TC
wastes which also are described with a RCRA listed waste code.  EPA applied a series of filters
to the remaining wastestreams to obtain the subset of wastestreams reported in the TC Survey
that will be affected by the Phase II LDR rule.
        Exhibit 2-2 indicates the effect these filters have in  reducing the total volume of waste
that should be considered as affected by the Phase II LDR rule.  The TC survey includes data on
740,000 tons of TC organic waste that is land disposed in units other than CWA or UlC-
permitted units.  Nearly 60 percent of these wastes, or 430,000 tons per year carry a listed waste
code (e.g., F037, petroleum refining waste) in addition to a TC code.  The Phase II LDRs will
require that listed wastes that also carry an organic TC characteristic code to meet  treatment
standards  for all constituents included in the UTS table.  Thus, it is possible for a listed waste,
such as K048  (dissolved air flotation float  from the petroleum refining industry), that also carries
the TC code for benzene (D018) to require treatment for more than the 15 constituents included
in the K048 BDAT-derived treatment standards. (See 40 CFR 268.41 and 268.43 for the current
requirements for K048 waste.). After a wastestream-specific review of the data, EPA determined
that in nearly  all cases, meeting the treatment standards based on the listed code would also meet
the treatment standards that will result from the Phase II LDRs.  Thus, to achieve a more
accurate estimate of the quantity of TC waste affected by the rule, wastes carrying  both listed and

characteristic codes should be subtracted from the total quantity of TC wastes if they do not
require further treatment as a result of the Phase n rule (see Exhibit 2-2).  EPA identified only
290 tons per year of nonwastewater and 290 tons per year of soil with both listed and
characteristic codes that would require additional treatment because of underlying constituents
that would have to be treated to reach UTS  levels.
       The quantities EPA is using in its cost analysis are based on projections made from data in
the TC Survey for the year 1995.  Because EPA  used 1995 as representative steady state volumes,
it discounted waste that would be  generated  in 1995 due to the closure of surface impoundments.
EPA did not consider roughly 20,000 tons per year of reported waste in its projection of steady
state generation because the waste was generated as part of surface impoundment closures. EPA
does not expect additional surface impoundment  closures generating TC organic waste to occur
since the four-year minimum technology retrofit periods (under authority of RCRA 3005(j)(6))
for both the TC identification rule and the F037  and F038 listing will expire by early  1995.
However, these volumes may require treatment in the first year following promulgation of the
rule, therefore increasing the estimated cost of the rule in that year.
       The final subset of the TC survey  that EPA used for its cost analysis consisted of
approximately 167,000 tons of nonwastewater, 94,000 tons of soil, and 34,000 tons of  debris.
These  quantities are the sum of 569 nonwastewater streams, 266 soil streams, and 569 debris
streams.3
       After culling out wastes  as described  above, 47 facilities remained.  Eight of these facilities
provided confidential business information (CBI) data.  Of the 39 non-CBI facilities,  17 (or 44
percent) were petroleum refineries, and an additional 12 (31 percent) were commercial waste
management facilities.  Exhibit 2-3 indicates how quantities of TC waste affected by the Phase n
LDRs  are distributed across SIC codes. Exhibit 2-4 indicates how quantities of TC waste affected
by the  Phase n LDRs are distributed across states. Because three of these facilities did not
provide data (e.gl, constituent concentrations) necessary for the benefits analysis, only 36 were
used to produce the results included in  Chapter 5 of the RIA.
   ^The quantities used in this analysis vary slightly from those in the accompanying capacity analysis. The capacity
analysis reports 223,000 tons of non-wastewater, 70,000 to 120,000 tons of soil, and 34,000 tons of debris. The difference
between the non-wastewater  quantities used here and in the capacity analysis stems from our using 1995 projections (as
opposed to 1994) and our exclusion of closure wastes.

Characterization of Wastes                                  '                         Page 2-11


The survey found that the vast majority of TC nonwastewaters are currently managed off-site.
The most frequently reported constituent in the organic TC wastes was benzene; the most
common waste code among nonwastewaters was D018, constituting 61 percent of the volume
requiring off-site commercial treatment. Exhibit 2-5 presents the distribution of affected waste by
waste code.

       2.1.2   Coke By-products and Chlorotoluene Wastes
       The coke by-product wastes hazardous waste listing rule, promulgated on August 18, 1992
(57 FR 37284), identified seven hew hazardous waste codes - K141, K142, K143, K144, K145,
K147, and K148.  Although there are large wastewater and nonwastewater volumes of coke by-
products, none is expected to be land disposed.  On-site processes constituting treatment (i.e.,
coking) are the most economic management method for these wastes and are widely practiced
among coke and tar refining facilities.
       EPA estimates that there are approximately 30 tons of chlorotoluene wastes (i.e., K149,
K150, K151) land disposed per year.

2.2    Wastes Already Regulated by the LDRs and Affected by Regulatory Changes

       2.2.1   Wastes Affected by Universal Treatment Standards
       The Phase II LDR rule will establish universal treatment standards (UTS). These
standards will update nearly all current concentration-based treatment standards with constituent-
specific UTS concentrations.  While the Phase n rule sets UTS levels for both wastewaters and
nonwastewaters, EPA expects that the UTS levels will have negligible cost effects on wastewaters,
given that nearly all listed-waste wastewaters are managed in tanks and never land disposed.
However, EPA evaluated the impacts of applying UTS levels to hazardous nonwastewaters.
        EPA assembled a database of the current concentration-based standards (i.e., BDAT
standards)  and a database of the universal treatment standards.  EPA then merged these
databases on a waste-code basis to determine the specific waste codes and constituents for which
treatment standards would be changing. EPA determined that treatment standards for one or
more constituents would change for 155 waste codes, and that in all 498 waste code/constituent

Characterization of Wastes                                                            Page 2-13


treatment standards would be altered. Appendix 8 shows which constituents will be changing for
each of these waste codes.
       Using engineering judgment* EPA evaluated what shifts in management practices the
changes in concentration-based standards for these 155 waste codes would cause.  EPA
determined that relatively few waste codes would be significantly affected, i.e., allow the use of a
different treatment, and that only two parameters, total and amenable cyanide concentrations,
would be responsible for all shifts in management practices.
       EPA believes that the lack of impact of implementation of the UTS standards is due to
two causes.  First, generally the direction of all concentration-based standards for the constituents
within a treatability group must be the same before a waste can be managed differently. That is,
constituent standards, must either decrease or remain the same if a less stringent treatment is to
be allowed.  It would not work, in general, if some constituent standards decrease while others
increase.  Second, stabilization is usually the most preferable way of treating contamination with
metal constituents, regardless of the concentration-based treatment standard that must be
attained.
       EPA identified twelve waste codes that had existing treatment standards for cyanide for
which concentration standards would be increased (i.e., become less stringent) by a factor of 10 or
more:  F011, F012, P021, P029, P030, P063, P074, P098, P099, P104, P106, and P121.  EPA used
1991 Biennial Reporting System (BRS) data to determine which wastestreams carried one or
more of these waste codes. Exhibit 2-6 presents these wastestreams and indicates how  EPA
arrived at its estimate of the quantity of waste affected by the UTS.  For each wastestream
included in Exhibit 2-6, EPA again applied engineering judgment, this time to determine if the
combined treatment standards for the wastestream, based on all the waste codes present, would
allow a  less expensive treatment, typically stabilization, to take the place of the BDAT treatment,
alkaline chlorination.  Very, often, the pressure of an origin waste code not exhibiting cyanide,
                                                                   \
would dictate that treatment based on incineration would still be required; thus there would be no
change in treatment technologies. EPA's analysis indicates that a total of 1,209 tons of waste
could have been treated using a less expensive treatment technology in 1991 if the UTS had been
in place.  EPA  assumes that this result is the best projection for the future quantity of waste that
will be affected by use of the UTS.

       2.2.2   Wastes Affected by Modifications to Hazardous Waste Recycling Regulations
       The Phase II LDR rule also broadens the scope of an existing exclusion to the definition
of solid waste to allow certain materials to be recycled in an environmentally beneficial manner.
This section provides a brief background of historical developments related to the definition of
solid waste before explaining how EPA assessed what types of waste will be affected by changes in
the regulations.
       In the January 4, 1985, final rule (50 FR 639), known as the LDR framework rule, EPA
promulgated an exclusion from the definition of solid waste for secondary materials that are
recycled in a "closed loop" (i.e., returned to the original production process in which' the material
was generated).  According to the framework rule, to be considered a closed-loop process three
conditions must be met:

       (1)    The  secondary material must be returned to the original process
              without undergoing significant alteration or reprocessing;

       (2)    The  production process to which the unreclaimed materials are
              returned must be a primary production process (i.e., a process that
              uses  raw materials as the majority of its feedstock, as opposed to a
              secondary process that uses spent or scrap materials as the majority
              of its feedstock); and

       (3)    The  secondary material must be returned as a feedstock to the
              original production process and must be recycled as part of the
              process, as opposed to an ancillary process.

       The Phase II LDRs will make it easier for industry to recycle materials in an
environmentally beneficial manner by removing the second of the three conditions above. The
Agency expects that the only effect of this change will be for K069 wastes (emission control dust
from secondary lead smelting), since this is the only waste from a secondary process listed as
hazardous.

       To determine the quantity of K069 affected by this change, EPA analyzed data from the
1991 BRS database.  Exhibit 2-7 indicates the quantities of K069 generated in 1991 and how they
were managed. .EPA expects that the result of the modification to the exclusion of the definition
of solid waste will be to allow recycling for all waste with K069 only. Wastestreams with codes in
addition to K069 were included only if the additional codes corresponded to characteristic levels
of constituents regulated by the BDAT standards for K069 (i.e., lead and cadmium).  K069
wastestreams with other codes (e.g., D010 for selenium toxicity) were not included in this analysis.
Exhibit 2-7 indicates that 4,402 tons of affected K069 were generated in 1991. Of this amount,
921 tons (i.e., 614 plus 298 plus 9) were recovered through recycling processes such as high
temperature metals recovery (HTMR) and secondary smelting. Accordingly, EPA assumes the
quantity of K069 potentially affected by the Phase fi LDR rule is the remaining 3,841 tons of
K069.  In  light of the modifications to the definition of solid waste, this quantity of K069 now will
be suitable for management using recovery technologies. Nine facilities account for the affected
waste.

2.3    EFFECTS OF WASTE MINIMIZATION
              In the Phase II Proposed Rule, the Agency accounted for the effects of waste
minimization directly in the volumes used in the RIA from the TC Survey database. Where
respondents to the survey indicated that they were in the process of (or had near-term plans to)
reduce their waste volumes through waste minimization activities, these estimated reductions were
      1                                                          \
subtracted from the overall volumes on a facility-specific basis.  These adjusted volumes became
the basis for the regulatory analysis of the Phase n standards.
       However, in the RIA for the proposed rule, the Agency raised two concerns regarding its
accounting of waste minimization. The first concern was the absence of waste minimization as a
potential least-cost compliance alternative for the regulated community in the RIA.  The second
issue raised was effectively whether the waste minimization identified in the TC survey should be
assigned as a part of the baseline scenario or the post-regulatory scenario in the RIA.  In other
words, would the waste minimization activities identified in the TC survey have been implemented
in the absence of the Phase n rule.

       For this Phase H Final Rule RIA, the Agency performed a separate waste minimization
analysis.  Using the TC Survey as its basis, the Agency performed a more detailed accounting of
waste minimization, which also addressed the concerns in the proposed rule analysis. The section
below describes the methodology and presents the results behind this waste minimization
accounting.

       23.1           Methodology
       The methodology for the waste minimization analysis follows six steps:

      " (1)    Develop a profile of the industries affected by the Phase n rule that indicated
              plans for waste minimization in the 1992 TC Suvey Database.

       (2)    From the industry profile, select industries to examine in the waste minimization
              analysis which would be representative of the TC waste universe.

       (3)    Make telephone data verification calls to facilities within the industries identified
              in Step 2.

       (4)    For the facilities participating in the verification, determine the cost components
              for the post-regulatory and waste minimization scenarios for all wastestreams.

       (5)    Estimate the total costs/cost savings for the waste minimization and the post-
              regulatory (i.e.: without waste minimization)  scenarios.

       (6)    Extrapolate results to TC waste universe, and determine overall cost/cost savings as
              the difference between the post-regulatory and waste minimization scenarios.
                          "                      '                     '
       The first three steps focus on the characterizing the waste subject  to minimization and are
discussed in greater detail below.  The last three steps focus on estimating the cost impacts of
waste minimization.  These impacts are  presented 4n detail in Chapter 3.

Page 2-20	Characterization of Wastes


       Step 1.  Develop a profile of the industries affected by the Phase II rule that indicated
plans for waste minimization in the 1992 1C Suvey Database.  The Agency employed the TC
Survey to construct the industry profile for the waste minimization analysis.  However, not all of
the wastestreams represented in the TC Survey are amenable to waste minimization.  Therefore,
the Agency eliminated wastestreams to derive the relevant universe for the waste minimization
analysis.
       The TC survey contains 316,000 tons of TC wastes that are subject to the Phase n rule.
(This is equivalent to the volume after Reduction 1 discussed in Section 2.1.1.)  As all of the
waste subject to the Phase n rule is not amenable to waste minimization, waste  minimization was
not considered for wastestreams from the closure of surface impoundments, remediation-derived
wastestreams, wastestreams described as soil, and wastestreams described as  sporadically generated
debris. These wastes were eliminated based on the assumption that they are one-time generated
wastes and annual waste minimization cost savings would be small, if any. Exhibit 2-8 shows
pictorially how the TC waste tonnage was reduced from 316,000 tons to the "reduced data set" of
197,000 tons.                                                                 ,
       The "reduced data set" was then divided into three sections based on the facility name I
knowledge of what that facility does:  (1) commercial TSDs, (2) CBI, and (3) industrial waste
generator/treater. The largest potential for waste minimization is  present at the industrial waste
generator/treater.
       Commercial TSDs receive waste from generators. The waste minimization potential at the
commercial TSDs itself is minimal.  The Agency examined the possibility of  tracing these waste
volumes to the generator through use of the Biennial Reporting Survey (BRS).  However, early
effort on this approach proved ineffective,  and refinements would have been time consuming,
with uncertain results. The Agency acknowledges that  there are potentially large savings from
waste minimization which is not accounted for due to this limitation.  Appendix  I presents the
large quantity wastestreams reported by commercial TSDs that were characterized for waste
minimization potential.
       For CBI facib'ties, no wastestream specific information was publicly available (i.e.: no
information was non-CBI).  The CBI universe of generated waste was assumed to be similar to
the non-CBI generated waste, and the cost savings from the non-CBI analysis were extrapolated

to the CBI wastes.
       The results of this data analysis identified 86 non-CBI facilities that responded to the 1992
TC survey.  Approximately 87 percent of the facilities that remained were in the petroleum
refining industry and the organic chemical manufacturing industry.
       Step 2. From the industry profile, select industries to examine in the waste
minimization analysis that would be representative of the TC waste universe.  As the petroleum
refining and organic chemical industries represented the 87% of the volume of wastes subject to
the Phase n TC LDRs,  these two industries were selected to represent the universe of TC wastes
for the purposes of the waste minimization analysis. From these two industries, 16 facilities were
identified that both land dispose of their TC wastes on-site and had indicated that they are
pursuing or plan to undertake waste minimization activities.
       The decision  to concentrate on these facilities for phone contact was based primarily on
two considerations.  First, it was believed that facilities that relied on on-site treatment, primarily
land farming or other land application, such as surface impoundments, would have a more
immediate need, with the imminent promulgation of the Phase n TC LDR treatment standards,
to institute waste minimization activities necessary to reduce the volume of TC wastes pro
The fact that these facilities had also indicated on the TC survey that they were pursuing or were
planning to  undertake waste minimization lent support to this consideration.
       Second, the waste volumes  generated by these facilities were deemed sufficiently
representative of the universe of the TC wastes subject to the Phase n TC LDRs to extrapolate
any cost savings from the minimization of .these wastes to the remaining balance of the wastes
deemed amenable to waste minimization. This consideration took into account that a major
component of the newly identified  TC wastes was various tank bottoms from crude oil storage and
from various intermediate distillate storage.

       Step 3. Make telephone data verification calls to facilities within the industries
identified in Step 2.  To confirm the information on waste minimization provided in the 1992 TC
survey, EPA attempted to contact the 16 facilities mentioned above. In addition, if the facilities
were willing to provide cost savings information, such data would be collected from up to nine
facilities.                                 •      '

       The Agency developed a telephone protocol to verify the information in the TC survey
database concerning facilities planning to perform waste minimization on Phase n wastestreams.
The telephone protocol and the results from the telephone calls are documented in Appendix J.

       2.3.2   Results of Waste Minimization on Affected Universe

       The waste minimization analysis found that approximately 21,000 tons of waste would not
need to be treated due to waste minimization activities.  This total quantity represents 14,100 tons
of petroleum refinery tank bottoms, 6,400 tons of petroleum refinery lime sludges, and 65 tons of
regenerated spent catalyst.  The effects of waste minimization on each of these waste types are
discussed in greater detail below.

       "Reduced Data" The "reduced data" contains 197,000 tons.  Exhibit 2-9 presents this
"reduced data" broken out by industry, generation category and physical form. Of this "reduced
waste", 35 percent is associated with CBI facilities; 46 percent is associated with commercial
treatment, storage, and disposal facilities  (TSDs); the remaining 19 percent is associated with
industrial waste generator/treater.  The petroleum and petrochemical industry accounts for 87
percent of the waste at industrial facilities. The waste at the industrial waste generator/treater has
the highest potential for determining cost savings from waste minimization.
       The generation category of "tank clean out" is a derivative of the replacement of surface
impoundments with tank systems.  The waste quantity in this category is the estimated quantity of
sludge generated in these tank systems.  Because waste minimization would take place before
wastestreams entered the tank system, and the type of waste entering the tank systems is not well
known, the waste minimization potential  of these wastes was not evaluated.

       Petroleum and Petrochemical Industry Analysis. Routinely generated wastes (8,000 tons)
are dominated by a single large wastestream.  Shell Oil - Wood River (survey 27) reported a 6,400
ton dewatered lime sludge generated from treatment of benzene contaminated groundwater,
dewatered in a filter press. The facility plans to perform waste minimization on this wastestream.
A follow up phone  call was made to the facility (see Section 3.2) to verify  this information.

       Sporadically generated wastes (13,350 tons) are dominated by "tank bottoms."  Eight "tank
bottom" streams account for 13,270 tons. Three petroleum refiners indicated waste minimization
of tank bottom wastes were being planned or considered.

       Additional Tank Bottom Wastestreams.  The TC Survey database was searched to find
additional "tank bottom" wastestreams. A total of 22 additional streams were found by searching
the waste description field for "tank bottom." Of these, six were wastewaters, two were soils, and
one was a wastewater treatment sludge. The remaining 13 streams from various industries range
in quantity from 0.5 tons to 281 tons and sum to a total of 738 tons.  These tank bottoms were
not included in the waste minimization calculations.

       Catalyst Wastestreams. Conversations with two petroleum refiners involved future plans
to recycle catalyst wastestreams. Therefore, the waste description field of,the TC Survey database
was searched for catalyst wastestreams.  Five wastestreams were found.  The largest was 232 tons
of "OHC catalyst and HC1 filter elements" generated by Georgia Gulf Corp. The next largest was
40.5 tons of "spent catalysts and support material from  petroleum and refining" generated by
Mobil Oil.  Marathon Petroleum generated  12.5 tons of "replacement of catalyst from 77C
reactor." Ashland Chemical Co generated 7.5 tons of "catalysts fines  from VGO reactor, catalyst
change." Vulcan Chemical generated 3.9 tons of "spent EDC catalyst from the production of
EDC," however, this wastestream is not in the spreadsheet because it also contains a listed waste
code.

       Organic Chemical Industry. The Agency was unable to contact any facilities that would
participate in the verification of data, and therein be included in the waste minimization analysis.

2.4    LIMITATIONS OF THE ANALYSIS
       In this RIA, EPA is not considering the impacts of the rule with regard to lab packs or
newly regulated characteristic pesticide waste (D012-D017).  The standards for these classes of
wastes vary only slightly from the original standards, and thus, no significant costs or benefits are

-------
Page 2-26                                                             Characterization of Wastes


expected.  In addition, these waste volumes are expected to be negligible when compared with
other wastes addressed in the Phase n rule.
       EPA has used data from the TC Survey and the BRS to characterize the affected
universe.  Both of these data sources have limitations. For instance, hazardous debris was not
formally defined by EPA until July 1992, several months after information for both of the data
sources used was submitted. Databases such as the TC Survey and the BRS may also be
inconsistent with each other because of differences in the information submitted and the
procedures used for structuring data.
       EPA queried the 1991 BRS to estimate the quantity of solids, sludges, and soils that have
only organic TC wastecodes (i.e., D018-D043). This query indicated a total quantity of 193,000
tons, with 70 percent  of this comprised of D018 streams.  This estimate compares well with the
estimates based on the TC survey that are used in this RIA.
       EPA's projections of TC waste volumes take into account waste management process
modifications indicated in the TC Survey.  To the extent that plans for modifications have
changed, EPA's estimates for TC wastes may err.  Underestimates and overestimates could resulL
from changes in waste management operations that were not indicated in the TC Survey.
       Finally, the RIA overlooks some degree of regulation of the land disposal of TC wastes
that may presently be occurring. California has enacted legislation that requires that treatment of
wastes containing volatile and semi-volatile contaminants before land disposal.  The legislature of
California has postponed the effective date of this regulation until January 1,1995,4 and so EPA
believes that these regulations should not -be reflected in the affected universe considered for the
RIA.

         COSTS OF RESTRICTING THE LAND DISPOSAL OF PHASE U WASTES

       In this chapter, EPA estimates the incremental cost of restricting the land disposal of
Phase n wastes by estimating both the costs attributable to post-regulatory management of the
waste and the costs associated with the current (or baseline) management of the same waste. The
incremental cost is the difference between the post-regulatory cost and the baseline management
cost.

3.1    COST ANALYSIS METHODOLOGY
       Because of differences in available data, EPA developed separate methodologies for each
type of waste affected.  The discussion that follows describes EPA's methodologies for this
analysis.

       3.1.1   Organic Toxicity Characteristic Waste
       The organic toxicity characteristic wastes addressed in the Phase II LDR rule and the
description of available data were discussed in the previous chapter.  Using the data from the TC
Survey, EPA was able to develop facility-specific cost estimates for the post-regulatory treatment
of these wastes. EPA approached this part of the cost analysis using the following five steps:

Step 1.        Create a subset of the TC Survey (and its resulting database) for a more efficient
              cost analysis by removing wastes that are not affected by the Phase n LDR rule
              (e.g., wastewaters).

Step 2.        For each wastestream in the resulting cost analysis database, review all available
              information and assign treatment technologies under the post-regulatory scenarios.

Step 3.        Collect appropriate unit cost information for treatments assigned.

Step 4.        Calculate testing and recordkeeping costs.

Step 5.        Create a model to process data and summarize results.

These steps are discussed in detail below.

       Step 1. Create a subset of the TC survey database for a more efficient cost analysis.
The original TC survey database described in Chapter 2 contained 91 facilities and over 900
wastestream records. Many of these wastestreams (e.g., organic TC wastewaters managed in
CWA permitted units, are unaffected by the Phase n LDR rule, as discussed in Chapter 2;
consequently, EPA removed them in developing a subset of the database for use in the cost
analysis.  In addition, EPA removed any waste streams for which the projected 1995 generation
was zero. Exhibit 3-1 summarizes the subset of the TC survey database used for the cost analysis.
The subset contained facility-specific data for each of the 47 facilities that EPA determined would
be affected by the Phase n LDR rule.  These data included over 700 wastestream groups, which
represented combinations of physical form and waste code, consisting of 295,000 tons of affected
waste, soil, and debris.

       Step 2. For each wastestream in the resulting cost analysis database, review all
available information and assign treatment technologies.  For the organic TC wastestreams in
the data  subset used for the cost analysis, EPA reviewed data records, including the original
completed questionnaires, for each wastestream and made  a wastestream-speciGc determination of
the treatment technology required to achieve the  universal treatment standards promulgated in
the Phase n LDR rule for  the TC constituents as well as for any underlying constituents.  EPA
assumed  that the treated wastes would be disposed of in a  Subtitle D landfill.  The baseline
management practice was in all cases land disposal at the facility.1

       —     In assigning technologies to treat TC nonwastewaters. EPA followed general
              guidelines on how these wastes would be treated. For oily TC nonwastewaters,
              such as wastes that are derived from hydrocarbon, olefin or petroleum production .
   1 EPA used the designation "landfill-oflsite" for wastes disposed of at commercial facilities receiving wastes from
generators.                                                      •

(tank bottoms, gasoline, oil-water emulsions), depending on the oil content, EPA
assumed that any of the following technologies would be employed: fuel
substitution, chemical treatment, critical fluid extraction, thermal desorption, or
biodegradation.  However, EPA assumed that TC wastes from hydraulic oils or
transformer oils would require incineration in a TSCA-pennitted incinerator.

For volatile TC organics, EPA assumed that low temperature thermal desorption,
critical fluid extraction, fuel substitution or biodegradation would reach the
required levels. For pesticides and other halogenated TC wastes either high
temperature thermal desorption or critical fluid extraction  followed by incineration
of residues was assumed.

Finally, EPA assumed incineration could always meet the treatment levels.
However, where certain contaminants exist, incineration was less likely to be used:
volatile toxic  metals (particularly As, Hg, Se, Pb); toxic nonmetal-oxide formers; (
corrosive gas-forming halogens; high sodium,  calcium, or silicates in the waste; ana—
corrosive inorganic compounds.  For residues from incineration, EPA generally
believes that  low temperature thermal desorption would be used for uncombusted
volatiles, and stabilization for metals.  Where several technologies applied for a
wastestream,  EPA generally chose the least costly technology.

For soil contaminated with organic TC wastes, the approach was similar to that
used for nonwastewaters: treatment was selected that would meet  the universal
treatment standards in the Phase n LDR rule. To estimate the cost of treating
organic TC soil, EPA first reviewed the TC survey database to select the most
likely waste treatment.  EPA reviewed the waste description, constituent, and
waste management information on each soil wastestream.  For soils contaminated
only with volatile organic compounds, EPA assumed that vapor extraction or some
form of thermal desorption would be used in both soil treatment alternatives.  If
the waste description or constituent information indicated  that toxic metals were

Costs                                                                               Page 3-5


              present, EPA generally assumed that the residual from treating the organic would
              require stabilization.  EPA assumed that semi-volatiles, non-volatile, and complex
              mixtures of contaminants would generally require incineration. In cases where a
              survey respondent indicated specific plans for treating the waste, EPA assumed this
              treatment would be selected. EPA did not adjust the data to account for the
              potential use of treatability variances for contaminated soil.

              To determine treatment under each regulatory scenario for debris contaminated
              with TC wastes. EPA used a'n approach similar to that described above for soils.
              However, for debris more emphasis was placed on the waste matrix. For instance,
              EPA assumed that combustible wastes (e.g., contaminated rags and fabric filters)
              would be incinerated, as would complex mixtures of relatively small objects. EPA
              also assumed that washing or chemical extraction would be used for larger objects
              that would require a great deal of size reduction to allow thermal desorption or
              incineration.

       After technology assignments were made, EPA determined whether in the post-regulatory
scenario treatment would occur on-site or off-site.  EPA relied on the on-site/off-site designations
in the current TC survey database (as developed by the capacity program branch); these
designations show that over 99 percent of the TC wastes will be treated off-site (i.e., at
commercial facilities). These designations were completed at the time the data were collected as
part of an extensive review of survey responses, including follow-up telephone conversations with
facility contacts. For this RIA, EPA reviewed each facility's permit status from a recent RCRIS
inventory to determine if any of the facilities designated in the database as "off-site for treatment"
had active RCRA permits, or have applied for a RCRA permit for on-site treatment. EPA found
only one facility that had been issued a RCRA treatment permit, and eight others that had
applied for treatment permits.  For these nine facilities, EPA changed the designations to "on-site
for treatment."               •
       To make its analysis more efficient, EPA examined the number of wastestreams and
volumes of waste for each of three categories, nonwastewater, soil, and debris, and determined a

-------
Page 3-6
wastestream volume threshold above which over 95 percent of the affected volume would be
accounted for. The thresholds were 80 tons per year per wastestream for nonwastewaters, 100
tons per year for hazardous soil, and 25 tons per year for hazardous debris.  For these waste
streams, a speciflc technology was not assigned; rather, an average treatment cost developed for
each physical form was used. These average costs were calculated by first examining the waste
streams with specific technology assignments and calculating the average for each category.  By
employing these thresholds, EPA was able to reduce the need for wastestream-specific technology
assignments, while still accounting for more than 95 percent of the waste volume. Average  costs
were also assigned to wastestreams that did not have sufficient data to make a technology
determination, as was often the case.

       Step 3. Collect appropriate unit cost information for treatments assigned. Once
wastestream-specific technology assignments were made, EPA estimated the unit costs for each  .
treatment technology. EPA examined several studies and sources for unit costs (see Appendix C
for more discussion of unit cost and their sources). First, EPA conducted a thorough literature^
search to determine costs and prices that have been effective over the past two years.  In
addition, EPA reviewed .nearly 100 Superfund RODs which were signed in 1993 to evaluate
information given about the cost of remediation and off-site treatment.  Finally, EPA contacted
eight commercial treatment suppliers who provide customers with thermal treatment and
stabilization for organic TC waste. When necessary, EPA used off-site unit costs from "1990
Survey of Selected Firms in the Hazardous Waste Management Industry," Final Report, July 1992,
U.S. EPA Office of Policy Analysis (OPA), or EPA's "Cost and Economic Impact Analysis of
Land Disposal Restrictions for Newly Listed Wastes and Contaminated Debris (Phase I LDRS)
                              *
Final Rule," June 30,1992.  Because vendor price quotes and  literature sources usually report
unit costs as a range, EPA took the mid-point of each range and then averaged multiple sources,
if necessary, to determine a single unit cost for each technology.
       The unit costs employed in this analysis assume subtitle D disposal for treated TC wastes.
Since virtually all the waste is currently disposed of at commercial facilities (see discussion above),
EPA assumed that transportation costs would be the same in both the baseline and  post-
regulatory scenarios.  Finally, when data allowed, as was  the case for commercial incineration

prices, EPA adjusted its unit cost values to reflect economics of scale for treating large quantity
wastestream.

       Step 4. Calculate testing and recordkeeping costs. The development of testing and
recordkeeping costs  is discussed in detail in section 3.1.4. For organic TC wastes, EPA applied
the appropriate baseline and post-regulatory testing costs for each wastestream as well as a
facility-specific recordkeeping cost.

       Step 5. Create a model to process data and summarize  results.  EPA developed a series
of spreadsheets and  datasets to store the data.  Data manipulation was then performed using SAS
software as well as Lotus 1-2-3.  For each wastestream in the database, EPA determined the cost
of the baseline and post-regulatory management practice.  For example, if a nonwastewater
wastestream of 1,000 tons per year had a baseline management cost of $75  per ton and a post-
regulatory cost of $1,000 per ton for the standards set in the Phase n LDR rule, the
corresponding total costs for the wastestream would be $75,000 in the baseline and $1,000,000 in
the post-regulatory scenario. The incremental treatment cost in  the post-regulatory scenario
would be $925,000.
       Costs for each wastestream were summed for each facility by waste  form  and post-
regulatory treatment technology. Testing and recordkeeping costs were added to the sum of all
treatment costs to determine a total cost per facility.

       3.1.2  Other Regulated Waste
       In addition to organic TC wastes and previously regulated hazardous soil, the Phase n
LDR rule affects coke by-product and chlorotoluene wastes.  EPA conducted a facility-specific
cost analysis for these affected waste streams.
       Based on an economic analysis of coke  by-product waste management performed for the
Coke By-Products Listing Final Rule,2 EPA believes that generators of these wastes will recycle

Products (Coking and Tar Refining) Industry, Final Report, June 1992.

rather than dispose of their waste in Subtitle C landfills.  Therefore, EPA believes no coke by-
product wastes wijl be affected by this rule.
       For chlorotoluene wastes, the baseline practice was assumed to be on-site disposal in a
Subtitle C unit. The post-LDR waste management method was assumed to be commercial
Subtitle C incineration.  The price, including transportation, is $1,320 per ton ($1,200 per ton for
incineration and $120 per ton for transport of waste 500 miles).

       3.1.3   Baseline Management Practices
       For wastes newly regulated by the LDRs, EPA assumed that the baseline management
practice is land disposal in a unit meeting Subtitle C requirements. The 40 CFR Part 264
requirements for such units include the installation of a liner and leachate detection and removal
system.  In addition, the units must have, provisions for ground-water monitoring, corrective
action, closure, post-closure care, and financial responsibility.
       For wastes currently regulated by the LDRs but affected by universal treatment standards,
EPA assumed that the baseline management practice is compliance with treatment standards us
the best demonstrated available technologies (BDATs) described in LDR technical  background  —
documents.  For K069,  baseline management practices are explicitly indicated in Exhibit 2-7,
based on analysis of 1991 BRS data.

       3.1.4   Testing and Recordkeeping Gists
       In addition to post-regulatory treatment costs,  EPA considered testing and recordkeeping
costs. (Testing and recordkeeping costs were included in the facility-specific cost estimates
developed for organic TC wastes.)  There are three times that testing might occur in the context
of the LDRs. First, testing may be needed to identify a waste as hazardous (e.g., TCLP);  this
would occur in the baseline scenario. Second, testing  may be needed in the post-regulatory
scenario prior to treatment to determine the number and concentration of constituents for which
treatment standards are set. Third, testing may be needed to determine in the post-regulatory
scenario if a wastestream meets concentration-based treatment standards.
       For this RIA, EPA assumes that generators of characteristic wastes will test each
wastestream in the baseline to determine the "waste's RCRA status, and they will then use their

knowledge of the waste to determine LDR applicability and underlying hazardous constituents.
EPA further assumes that waste-generating processes have a four-year effective life; i.e., after
four years a given process undergoes significant modification such that its wastestream must be re-
characterized. Generators of listed hazardous waste will not test before treatment, but will apply
their knowledge of the waste to determine LDR applicability.         .
       Post-treatment testing to demonstrate compliance is required for  wastes with
concentration-based  treatment standards and will be performed after each waste load  is treated.
EPA assumes that for regularly generated nonwastewaters, four waste loads are treated annually,
and for hazardous soils and debris, one waste load is treated annually.

       TC Nonwastewaters.  For TC nonwastewaters, all underlying constituents must be treated
to universal standard levels.  Therefore, the waste must be tested before  treatment to identify
underlying constituents. EPA assumes that a test for all F039 constituents would be conducted.
After treatment, the waste must be tested for those constituents identified in the first test, both
the original TC constituents and the underlying constituents. Based on the TC survey, EPA
estimates that the average wastestream will need to be tested for five constituents.
                                    •4
       Phase II Newly Listed Wastes.  The coke production wastes (i.e., K141-K145,  K147, and
K148) and the chlorotoluene wastes (i.e., K149-K151) will not require  a pre-treatment test
because generators can use their knowledge of the waste to determine applicability of the LDRs.
After treatment, these wastes will require testing to determine that the concentration  standards
have been met.  For each waste, there are ten or fewer volatile or semi-volatile organic regulated
constituents.                                                                        .

       Soil.   For newly regulated soil, pre-treatment testing for all F039  constituents must be
conducted to identify the number and concentration of constituents present.  After treatment, the
soil must be tested for those constituents initially determined to be present Based on the TC
survey, EPA estimates that the average wastestream will need to be tested for five constituents.

       Debris.  Newly regulated debris is the only debris affected by the rule and is not subject to
any testing requirements. Generators can use their knowledge of the waste to determine the
required treatment, and as long as the treatment is conducted properly, there is no testing
required to demonstrate compliance.

       Exhibit 3-2 presents the estimated incremental testing costs attributable to the Phase II
LDR rule.  In developing the estimates, EPA made several assumptions.  For each test, EPA
assumes that there is one waste sample and one QA/QC sample.  For each test, EPA also
assumes that a test for all FQ39 constituents is equivalent to a test for all the universal standard
constituents, although there are some small differences between the two sets of constituents.
EPA based testing costs on several sources including a March 4,1993, letter from Texaco to the
RCRA Docket TTCA, Emergency Rule Notice; an API letter to the RCRA Docket HWEP, for
the HWIR proposed rule; and EPA's testing cost analysis done in support of the HWIP.
       The Information Collection Request (ICR) for this rule, being prepared by EPA,
estimates that-the recordkeeping cost is $346 per wastestream. It is estimated to take one hour to
develop and submit the required notification and one quarter of an hour to retain copies of thi
documentation and notification.  EPA estimates that modifications to the waste analysis plan
required under 40 CFR 268.7 may cost each facility an additional  $350 in recordkeeping costs.

       3.1.5   Previously Regulated Wastes Affected by UTS
       EPA has identified one type of previously regulated wastes that may be affected by the
UTS: cyanide-bearing wastes. For these wastes, the Phase n LDR rule may potentially result in
a cost savings. The approaches used to estimate these savings are described below (also see the
discussion in Chapter 2).
       Cyanide-bearing wastes may be  affected because the UTS for cyanide is higher (less
stringent) than previous BDAT standards for some cyanide-bearing waste codes.  EPA identified
twelve waste codes that had existing treatment standards for cyanide that would be increased by
over a factor of ten.  EPA then used 1991 BRS data to determine which wastestreams carried one
              N
or more of these codes. For each wastestream, EPA applied engineering judgement to determine
if the combined treatment standards for the wastestream would allow a less expensive treatment,
i.e., stabilization, to take the place of the BDAT treatment, alkaline chlorination.
       In addition, the new consistency provided by the UTS will  help streamline the treatment
and management of all RCRA waste.  This streamlining can, in fact, result in significant cost
savings. For example, one commenter, DOW Chemical Co., reported that the UTS will result j
an annual savings of $366,000 for one of their plants because it will eliminate the need for
campaign burning, i.e., processing an individual wastestream through an incinerator so as not to
commingle residues.3 This plant has a rotary kiln processing 15,000 tons per year; thus, the
savings associated with the streamlining effect of UTS would be $24 per ton of waste incinerated.
EPA examined all prior LDR rules and determined that 2.3 million tons of waste annually would
require incineration.  Thus the maximum  potential savings associated with the streamlining effect
of UTS could  be as high as $55 million per year (2.3 million tons per year times $24 per ton).
EPA further extrapolated  this information to wastes undergoing physical/chemical treatment
because EPA believes that these types of treatment may also be conducted in campaigns.  EPA
estimates that  approximately 5 million tons per year of waste are treated by physical/chemical
treatment.  Because physical/chemical treatment costs are roughly  one-third of incineration costs,
EPA assumes  the savings associated with  the streamlining effect of UTS would be reduced
proportionally (i.e., $8 per ton).  Therefore, the maximum potential savings for wastes suitable for
   'EPA notes that it received many comments suggesting the UTS would increase costs. In general, however, these
commenters were assuming that the treatment of underlying constituents would be required for listed wastes. EPA
believes this erroneous assumption was the basis of their estimate of increase cost •

-------
Costs                                                                              Page 3-13


physical/chemical treatment could be as high as $41 million per year (5.1 million tons per year
times $8 per ton). Thus the total maximum potential savings would be $96 million per year. EPA
realizes that this characterization of savings resulting from the streamlining effect of UTS is based
on an analysis employing broad assumptions and therefore regards the estimate as the maximum
potential savings.  However, EPA believes that it is possible that there may be additional cost
savings resulting from the streamlining due to factors such as reduced labor requirements or
recordkeeping needs.

        3.1.6  Previously Regulated Wastes Affected by Recycling Modifications
        EPA has identified one type of previously regulated wastes that may be affected by the
recycling modifications: K069 wastes. For these wastes, the Phase n LDR rule may potentially
result in a cost savings. The approaches used to estimate these savings  are described below (also
see the discussion in Chapter 2).
        EPA determined that K069 wastes (emission control dust from secondary lead smelting)
would be affected by the Phase n provision redefining the recycling definition to  allow recycling
of secondary process wastes.  To estimate the potential cost savings, EPA used 1991 BRS data to
determine the quantities of K069 waste currently being managed under a variety of treatment
technologies.  EPA then used unit cost data for the treatment technologies to estimate the total
treatment cost avoided by the Phase n rule.               .    .

        3.1.7  Waste Minimization
        As discussed in Section 2,3 of this RIA, EPA performed a separate wziste minimization
analysis for the Phase n Final Rule RIA.  Using the TC Survey as its basis, the Agency
performed a more detailed accounting of waste minimization, which also addressed  the concerns
in the proposed rule analysis.  The characterization of wastes subject to minimization was
discussed in, Section 2.3. This section addresses the methodology used to assess the cost impacts
of waste minimization.

        The methodology for the waste minimization analysis follows six steps:

-------
       (1)    Develop a profile of the industries affected by the Phase n rule that indicated
              plans for waste minimization in the 1992 TC Survey Database.

       (2)    From the industry profile, select industries to examine in the waste minimization
              analysis which would be representative of the TC waste universe.

       (3)    Make telephone data verification calls to facilities within the industries identified
              in Step 2.
                    f
       (4)    For the facilities participating in the verification, determine the cost components
              for the post-regulatory and waste minimization scenarios for all wastestreams.

       (5)    Estimate the total costs/cost savings for the waste minimization and the post-
              regulatory (i.e.: without waste minimization) scenarios.
       (6)    Extrapolate results to TC waste universe, and determine overall cost/cost savi
              the difference between the post-regulatory and waste minimization scenarios.
The first three steps pertain to waste characterization and were discussed in detail in Section 2.3.
The last three steps pertain to the cost impacts of waste minimization and are discussed in detail
below.

       Step 4. For the facilities participating in the verification, determine the cost
components for the post-regulatory and waste minimization scenarios for all wastestreams.  The
costing methodology is designed to capture the true costs of waste minimization.  The
methodology addresses the capital investment costs, the operating costs, and maintenance costs
associated with implementing waste minimization technologies and operating practices.  If
information on regulatory and legal/liability costs could be obtained from the data verification
activity described above, such costs (and savings) would also be included in the cost calculations.

-------
Costs                                                                               Page 3-15


       The first step in the developing the potential costs (and cost savings) for waste
minimization activities was to identify the specific pollution prevention action that industry
planned to employ. For example, several petroleum refiners indicated in the TO Survey that by
dewatering tank bottoms (a D018 waste stream) and separating out sand/grit-type material, the
resultant oils could be re-introduced  to the feedstock for processing.
       Based on the database analysis and verification phone contacts, the following waste
minimization alternative actions were identified:

       •      Recycle of petroleum refinery oil storage tank bottoms;
       •      Reuse of petroleum refinery lime sludges as cement kiln feedstock; and
       •      Regeneration of spent catalysts.

       After identifying these waste  minimization activities, EPA developed conceptual
engineering flowsheets to depict the  action and identify potential costs for capital equipment and
operation.  The specific investment costs for each alternative were obtained and developed under
the following categories:

       •      Depreciable Capital Expenditures - Equipment, Materials, Site Preparation,
              Installation, Engineering/Procurement.

       •      Expenses - Start-up, Permitting (if available), Salvage, Training  (if appropriate),
              Working Capital, Disposal, Raw Materials, Utilities, Labor, Maintenance,
              Insurance.
                                                   %
       •      Operating Revenues - Eliminated Expenses, By-product Revenues.

       •      Economic Factors - Lifetime of Activity, Escalation Rate, Discount Rate.

       In Exhibit 3-3, EPA present the basis for each of the above factors.  An example
worksheet for calculating the investment costs and savings are shown on Exhibit 3-4.  The table

investment costs and allow comparison of alternative approaches to meeting the Phase n Rule
(i.e., invest in waste minimization techniques or simply treat the Phase n wastes by conventional
end-of-pipe technologies).                                         .

       Step 5. Estimate the total costs/cost savings for the waste minimization and the post-
regulatory (i.e.: without waste minimization) scenarios.  The net annualized waste minimization
savings were calculated by summing the separate annualized waste minimization cash flows for
each cost  element, adjusting the annualized cost for tax liabilities, and subtracting the adjusted
result from the post-regulatory compliance annualized costs (Exhibits 3-4 and 3-5). A 34 percent
corporate tax rate was assumed and capital equipment was depreciated on a double-declining-
balance method.  Both the pre-tax and post-tax net annualized savings are discussed.  Escalation
rates of 4 percent and discount rates of 7.5 percent were used for all cost elements.  The net
present value was calculated by dividing the  net annualized savings by an annualization factor that
is a function of the discount rate and life of the project. The project life equals the life
expectancy of the principle equipment item in the waste minimization alternative.
       Worksheets for each level, cost summary and financial calculations were used to insure all
costs are accounted for to the extent possible. Exhibit 3-5 presents an example worksheet for
adjusting potential costs and cost savings for taxes.
       Because tank bottom dewatering was performed at a number of facilities with significantly
different wastestream volumes, EPA created a series of model plants and developed individual
costs (normalized per ton of waste) for each model plant.  The costs were then graphed to
facilitate interpolation and  extrapolation of potential costs and cost savings for actual plants. For
example, a cost survey was developed for potential costs/cost savings for recycling of tank bottoms
at petroleum refineries where the wastestream volume ranged from 35 tons per year up to 5,280
tons per year.

       Step 6. Extrapolate results to TC waste universe, and determine overall cost/cost
savings as the difference between the post-regulatory and waste minimization scenarios. The
Agency calculated the annualized savings for each of the wastestreams, including extrapolating it

to the CBI volumes. The waste volumes which were included in the waste minimization analysis
made up 35% of the total on-site treated, non-CBI, non-wastewater, non-sporadically generated
wastes.  For CBI data, EPA used the "unit savings" calculated for the on-site treated, non-CBI,
non-wastewater, non-sporadically generated wastes, and applied it to 35% percent of the total
volume of CBI on-site treated, non-CBI, non-wastewater, non-sporadically generated wastes.

33,    RESULTS OF THE COST ANALYSIS
       Exhibit 3-6 summarizes the results of the cost analysis.  In total, the Phase IILDR rule
would have an incremental annual cost of $191 to $219 million (representing accounting or not
accounting for waste minimization savings).  Sixty-seven percent of this cost would be for the
treatment of organic TC nonwastewater wastes, and 16 percent and 17 percent would be for the
treatment of organic TC hazardous soil and debris.  In  addition, there may be a potential savings
of $2 million, associated with previously regulated waste affected by UTS and modifications to the
recycling definition.  The cost savings associated with waste minimization is estimated to be $25
million. Finally, the streamlining effect of UTS on the treatment of previously regulated waste
presents a savings ranging from $0 to $55 million for incinerable wastes and $0 to $41 million fat
wastes suitable for physical/chemical  treatment.                       -

       3.2.1   Organic TC Wastes and Other Newly Regulated Wastes
       As described above in Section 3.1.1., EPA conducted a facility-specific cost analysis for
those facilities managing organic TC waste.  Exhibit 3-7 shows a breakdown of results for all
organic TC wastes, i.e., nonwastewater, soil,  and debris. In Exhibit 3-7, there are estimates for
testing and fecordkeeping as well as  for treatment; all costs were derived on facility-specific
information.  These facility-specific costs are presented in Exhibit 3-8. In addition, Exhibit 3-9
presents detailed information on waste characteristics and baseline and post-regulatory treatment
costs. For each facility, this exhibit presents the waste quantity, the baseline and post-regulatory
treatment technologies and unit costs, total baseline, post-regulatory, and incremental treatment
costs, sorted by post-regulatory treatment technology and waste form.  Summaries of costs by SIC
code and state are also provided in Exhibits 3-10 and 3-11.                                •

•/  Cost livings associated with wast* minimization can b* attributed to the Phase II rula when a facility, 1n facing
Tocreased Mast* management costs under Phase 'II.  has an option that, while Incurring Incremental costs, can produce a
positive financial  return as compared to management under the Phase II cost structure.  However, EPA does not have
sufficient Information to claim that all waste minimization Investments are 100 percent attributable to the Phase II
rule.  To reflect this uncertainty, EPA presents  the total cost of the rule both with end without the potential cost
savings.

       Since EPA believes no coke by-product wastes will be landfilled as a result of the coke by-
product listing rule (August 18, 1992, at 57 FR 37284), EPA estimates that no costs will be
associated with the treatment standards for coke production wastes.  The incremental cost  for
chlorinated toluenes is estimated to be less than $0.1 million annually.
       The unit cost for the treatment of TC nonwastewaters averages $1,050 per ton. (The
average baseline cost is $30 million/year divided by 167,000 tonsfyear  = $180/ton)4. For TC
hazardous soils and debris, the unit treatment costs average $560 and $1,300 per ton, respectively.
       While the total incremental cost for the 47 facilities in the cost analysis is $219 million, the
average cost per facility differs substantially between captive (i.e., non-commercial) and
commercial  facilities. For the non-CBI captive facilities, the average  incremental compliance cost
for captive facilities is $1.4 million. (The range is  from $4,000 to $13 million, with a standard
deviation of $2.5 million.)  For the non-CBI commercial facilities, the average incremental
compliance  cost is $8.8 million.  (The range is from $300,000 to $22 million, with a standard
deviation of $7.7 million).
       The significance of the distinction drawn here relates primarily to the possible economic
impacts caused by the costs incurred. For the captive facilities, the potential for pass through of
costs is determined by the structure of the markets for the products associated with the
generation of the wastes affected by the Phase n LDR rule. There would be large variation in
elasticity, which determines the degree to which cost pass through is possible.  For commercial
firms, the primary market is for the waste management service.  The elasticity of demand for
waste management services might be expected to be more consistent  across commercial facilities.

       3.2.2 Previously Regulated Wastes Affected by UTS and Recycling Modifications
       As described in Sections 3.1.5 and 3.1.6, EPA estimated cost savings associated with less
stringent treatment standards for some cyanide-bearing wastes and avoided treatment costs for
K069 wastes due to the recycling definition.  Wastestream-speciGc data for cyanide wastes  is
presented in Exhibit 3-12.  As this exhibit shows, the baseline treatment cost for these wastes is
$66.6 million, and the post-regulatory cost is $66.5 million. In .other words, an incremental savings
   4 This compares well with EPA's estimated compliance cost of the TC identification rule, which estimated an
incremental compliance cost of $160Aon, in 1992 dollars. From U.S. EPA Background document Toricitv Characteristic

       3.2 J   Sensitivity Analyses for Organic TC Wastes
       Permit Modification Costs.  EPA conducted a sensitivity analysis to determine whether
permitting costs for the nine facilities for which it had originally assumed on-site treatment based
                                             >
on permit information in the RCRIS database would incur significant permit modification
EPA reviewed an earlier analysis to estimate permit modification costs on a per facility basis.
earlier analysis, conducted, in part, to support RCRA reauthorization and the corrective action
studies, assumed, that for on-site treatment, the permit application and process would cost $60,000
over the first two years, there would be no further modifications, and a renewal cost of $23,000
would be realized every five years.
       EPA applied this schedule of payments to the RIA analysis by assuming the following.
Since eight facilities have only submitted the first part of the permit application, they will need to
"modify" their application immediately (i.e., adjust the Part B application before submittal).  EPA
did not consider new operating costs associated with modified permits, such as worker training.
EPA assumed, conservatively, that permit modification would cost the same as a full application,
namely $60,000 in the first year.  EPA further assumed that renewals would take place every five
years for twenty years, roughly, the effective life of the treatment process.  Thus, EPA assumed
the facility-specific schedule of payments would be as follows:

       While this schedule of payments is conservative, for example, realizing the full $60,000 in
year one rather than over two years, EPA believes it approximates the order of magnitude of
permitting costs likely to be associated with this rule.
       Exhibit 3-14 shows the per facility present value and annualized cost and the total annual
incremental cost for six scenarios.  EPA calculated the costs for both eight and nine affected
facilities for three discount rates: 4 percent, 6 percent, and 10 percent. The period of over which
the cost is annualized is 20 years in all scenarios.

       The total annual incremental cost due to permit modifications ranges from $70,000 to
$99,000.  This would have no significant effect on the overall cost of the rule as developed in the
RIA, since the total annual incremental cost of the rule is $219 million.  The permit modification

costs associated with these nine facilities would increase the total cost of the rule by 0.05 percent
at the most, an effect well within the rounding error for the RIA cost calculation.

       TC Waste From Closures. EPA conducted a sensitivity analysis to determine the effect on
results of including the costs incurred as a result of TC waste generated during closure.  EPA
approached this order-of-magnitude estimate by reviewing the analysis of contaminated soil
conducted as part of EPA's HWIP analysis. According to EPA's earlier studies, as presented in
the HWIP analysis, of the total 2.1 million tons/year of affected soil, 160,000 tons/year are a result
of RCRA closures.  The ratio of RCRA closure-derived soil to all other remediation soil, then, is
0.16 to 1.94 (i.e., 2.1  minus 0.16). Using this ratio, EPA estimated the quantity of TC closure-
derived soil by multiplying the total quantity of TC hazardous soil, 94,000 tonstyear, by 8.25
percent (i.e., 0.16/1.94), calculating 8,000 tonstyear of closure-derived TC soil.
       Since EPA's estimated incremental annual cost for TC hazardous soil is $35 million, based
on 94,000 tons per year (i.e., $370 per ton), then an additional 8,000 tons of closure-derived TC
soil would have an associated incremental annual cost of $2.9 million. This would increase the
total cost of the rule by roughly one percent.  Exhibit 3-15 plots incremental cost as a function
the quantity of closure-derived TC waste.                               .
       This order-of-magnitude estimate encompasses four limiting assumptions. First, EPA
assumes that only soil will be generated in significant amounts during closure.  Second, EPA
assumes that the proportion of closure-derived TC soil to other remediation TC soil is the same
as the ratio  for all hazardous soil (i.e., including non-TC soil).  Third, EPA assumes the
technologies used for closure-derived TC soil will be the same as for TC remediation soil. A final
limitation is that it is impossible to determine how much overlap there is between the estimate of
hazardous soil reported in the HWIP analysis and the 94,000 tolas/year of newly  regulated TC
hazardous soils.  This indeterminable overlap affects the accuracy of EPA's estimate.

       Testing Costs. For its cost estimate, EPA assumes that there is one waste sample and one
QA/QC sample for each test performed. EPA also performed a sensitivity analysis of the testing
cost for affected TC wastes in which it varied (1) the frequency with which waste is tested for
identification, and (2) the number of wasteloads which are treated, and thus require testing, each

year. TC wastes must be tested to determine the underlying hazardous constituents. In the RIA,
EPA assumed that waste-generating processes have a four-year effective life; i.e., after four years
a given process undergoes significant modification such that its wastestream must be re-
characterized. For this sensitivity analysis, EPA varied the effective life of waste-generating
processes for TC nonwastewaters from 3 months to 10 years.  EPA assumed each TC soil
wasteload must be tested for identification purposes since TC soil is not generated by a specific
process.  EPA also varied the number of wasteloads tested per year.  For TC nonwastewaters,
the number of wasteloads tested each year varies from 1  to 12. Since EPA implicitly assumed
that soil is generated at one-fourth the frequency of TC nonwastewaters, the frequency of testing
for TC soil wasteloads ranges from once every four years to three times each year.
       Exhibit 3-16 presents the results of the sensitivity analysis.  Given the parameters specified
above, the total testing cost could range from $800,000 per year to $11.2 million per year, or a
negative  one percent to a positive four percent incremental change in the total cost of the rule.

       3.2.4   Waste Minimization of Organic TC Wastes

       The total cost savings estimate for the waste minimization analysis of the Phase n Rule
was approximately $25 million annually.  This is  made up of $22 million from tank bottoms
savings, and $3 million from lime sludges savings.  A description of these savings is provided
below.

       Recycle of Tank Bottoms. Oil product storage tank bottoms (referred to as tank bottoms
hereafter) represents one of the largest wastestreams in the database readily amenable to waste
minimization.  A number of alternative waste minimization alternatives were considered:

       •      Storage tank mixing to reduce deposition,
       •      Sludge coking, and
       •      Phase separation by centrifuge and recycle of recovered feedstock.

       Phase separation by centrifuge was selected as the most viable alternative due to its
applicability across all types of oil product tank bottoms and its general applicability in facilities of
various design.  Storage tank mixing and sludge or centrifuge solids coking are still viable
alternatives that may be implemented separately to, or in conjunction with, centrifuging on a
facility-specific basis to further reduce tank bottoms or solids disposal. They are, however, not
considered within this case study.
       A decanter type centrifuge was selected due to its ability to accept virtually any type of
pumpable liquid/solid mixture and its ability to operate in a continuous mode.  The decanter type
centrifuge is capable of a 98.5 percent oil/water/solids separation while producing a sludge cake in
excess of 40 percent solids.  For this case study a more conservative 90 percent oil/water
separation and a 95 percent solids removal with a 30  percent solids cake is assumed.  The
conceptual design is a three-phase (water, oil, and solids) decanter centrifuge with a 30 gallon per,
minute (gpm) capacity, mounted on a trailer with a 1,000 gallon feed surge tank, a 1,000 gallon oil
product tank, a five cubic yard dumpster for solids storage, and appropriate pumps and level
controllers. The initial capital investment costs were  calculated to be about $200,000 with a
salvage value of about $39,000 after a  15 year life;
       The oil product stream from the centrifuge is returned to the process stream as a resource
with a value of $16.00 per barrel. The water phase is discharged to the industrial sewer, and the
solids are disposed by either landfilling, if non-hazardous, at a cost of $75 per ton, or off-site
incineration, if hazardous, at a cost of $1,280 per ton. As the total quantity of wastewater treated
at the database facilities is not known, it is not possible to assign an incremental treatment cost to
the water phase.  It is suspected that the incremental cost would be insignificant.
       The potential annualized costs of the waste minimization alternative were calculated for
tank bottom quantities representative of the range of facility tank bottom generations in the
database -200 tons, 500 tons, 1,000  tons, and 5,000 tons per year. The annualized costs of the
post-regulatory compliance alternative, incineration and subtitle D disposal, are calculated over
the same project life as the waste minimization alternative (15 years) at the same escalation rate
and discount rate.  Both  annualized costs were adjusted for corporate tax liability. The net7
potential waste minimization annualized savings were calculated by subtracting the waste

minimization alternative costs from the post rule compliance alternative costs for the four tank
bottom quantities indicated above.
       Exhibit 3-17 provides the annualized pre-tax costs and savings associated with the waste
minimization alternative and the post-regulatory compliance alternative for various quantities of
tank bottoms representative of the generators found in the database. Column A (and E)
represents the quantity of tank bottoms, i.e., 200 tons per year.  Column B is the annualized pre-
tax cost of the waste minimization alternative (centrifuging) for the various quantities of tank
bottoms shown in Column A, i.e., $50,831 for annual tank bottom quantities of 200 tons per year.
Column C is the annualized pre-tax cost for incinerating (post-regulatory compliance alternative)
the post-Phase II Rule hazardous tank bottoms assuming no waste minimization is performed, i.e.,
$337,243 for annual tank bottom quantities of 200 tons per year.  Column D is the net annualized
pre-tax savings realized in implementing the waste minimization alternative and is calculated by
subtracting the waste minimization cost (Column B) from the incineration cost (Column C), i.e.,
$337,243 minus $50,831 equals $286,412 of net annualized pre-tax savings for minimizing 200 tons
of tank bottoms per year.  Column F is the annualized factor (AF) calculated using the formula
shown in Exhibit 3-4. The net present value, NPV, (Column G) is calculated by dividing the net
annualized  pre-tax savings (Column D) by the annualized factor, AF, (Column F). Column H is
the net annualized pre-tax savings on a per ton of tank bottom basis obtained by dividing the net
annualized  pre-tax savings (Column D) by the tonnage of tank bottoms (Column E). Likewise,
Column I is the net present value on a per ton of tank bottom basis obtained by dividing the net
present value (Column G) by the tonnage of tank bottoms (Column E).
       The net annualized pre-tax waste minimization savings ranged from $286,412 for 200 tons
of tank bottom per year to $7,804,774 for 5,000 tons of tank bottoms. A graph of the  potential
net annualized pre-tax savings per tank bottom quantities is shown in Exhibit 3-18.  The data
points are approximately linear and represent  a potential pre-tax annualized savings of about
$1,560 per  ton of tank bottoms.  The pre-tax net present value (NPV) ranged from $2,528,192 for
200 tons of tank bottoms to $68,893,674 to 5,000 tons of tank bottoms.

       The net annualized post-tax waste minimization savings ranged from $187,370 for
minimizing 200 tons of tank bottoms per year to $5,150,000 for minimizing 5,000 tons of tank

       Reuse of Lime Sludge. One petroleum refinery indicated they produced a 6,400 TPY
dewatered lime sludge from groundwater treatment that was contaminated with benzene and
petroleum liquids.  The facility stated that a cement kiln was willing to accept the sludge as
feedstock at a cost to the refinery.  The cost per ton was not given. Therefore, a cost of $50 per
ton was assumed based oh the cost for lime ($50/ton from Chemical Prices March 18,  1994).
Assuming no annual change in the charge for the lime sludge, reuse of the lime sludge would cost
$465 per ton less than end-of-pipe treatment. The annualized potential cost savings is $3,000,000.

       Regeneration of Contaminated Catalysts.  The TCDMS showed two refineries were
instituting regeneration of contaminated spent catalysts rather than waste disposal.  One refinery
stated they realized a savings of $37 per ton of catalysts by regenerating rather than disposing of
the catalyst.  Four refineries reported previous waste disposal of spent catalyst.  However, the
total volume for all four facilities was less than 65  tons per year. Potential savings were
determined to be insignificant. Note that one facility with 270 tons per year of spent catalyst
waste was instituting waste minimization; however, the catalyst wastestream was not listed in
TCDMS.

       Other Factors Affecting the Results. The  work assignment methodology was directed at
estimating the cost savings to industry from waste minimization  associated with compliance to the
Phase n LDR rule.  The analysis only covered newly identified TC wastes that were being
regulated  under this rule.  However, a significant percentage of these TC wastes are not amenable
to source  reduction or recycling waste minimization activities because they are:

       •      Wastes generated from closures and corrective actions.
       •      Wastes generated from remediation activities.
       •      Contaminated soils and debris.

-------
Costs                                                                                Page 3-43


       Among the reasons these wastes are not amenable to waste minimization activities include:

       •      These wastes are generally not routinely generated.

       •      Particularly in the case of contaminated media and closure and remediation wastes,
              the wastes are generated as a result of releases to the environment, and as such,
              once  the release has occurred and the wastes have been generated, there is little
              or no opportunity for minimization.

       •      Particularly in the case of contaminated media, it is often  the case that the
              concentration of the contaminant(s) of concern is too low to be economically
              recovered.

       It is important to note for this analysis that even though  many of the newly identified TC
wastes are  not amenable to waste minimization activities, other wastes subject to the Phase n
LDRs, such as residuals from manufacture of chlorotoluenes and coke, are amenable to waste
minimization activities.
       These estimates likely understate savings potential for two reasons. First, discussions with
regulated facilities suggest that there are newly regulated TC wastes being minimized that are not
included as part of the cost baseline developed for the Phase n  RIA. Savings associated with
these wastestreams have not been integrated into our savings estimate because of a desire to
maintain consistency with the cost analysis.  Second, we have given only cursory consideration to
wastes received by commercial  TSDs. The analysis presented in Appendix A indicates three of
the largest wastestreams received by TSDs have the potential for waste minimization.  In most
cases, there is insufficient information to determine the waste minimization potential for these
wastes at the generator level.  Since these wastes represent roughly half of the universe of newly
regulated waste, they may present additional waste minimization savings potential.

33    LIMITATIONS OF THE ANALYSIS
       Both the data used for this analysis and the methodologies developed have limitations.
The most important limitations are addressed below.

       •     The use of on-site/off-site treatment designations provided by the Capacity
              Programs Branch in their database (over 99 percent of the TC waste is designated
              for off-site treatment) may not reflect long-term management.  To the extent that
              EPA overestimated the quantity shipped off-site for treatment, EPA overestimated
              the cost of the rule.

       •     Our unit costs are based on off-site treatment and our earlier work for on-site
              treatment (see section 3.1.1).  Since there are wide ranges of unit costs for each
              technology, EPA has used the mid-point of the range.  To determine the effect of
              the wide range  of unit costs, EPA has run its model using the low end of the range_
              and the high end.  EPA found that the annual incremental cost of $219 million
              TC wastes should be viewed as a best estimate with a range of error from 60
              percent below this value ($87 million) to 65 percent above this value ($360
              million).
                        I               .
       •     The main source of unit costs are vendor quotes and are "prices" charged for
              treatment services. These prices measure the "cost" to waste generators who ship
              waste off-site or who hire on-site vendor services. Since these prices are
              determined by market factors, they are typically higher than the actual cost of
              treatment. Moreover, since these prices can include transfer payments—such items
              as insurance, interest, and profit in excess of full competition—they may
              overestimate the true social costs.                                         .

       •     For TC nonwastewater waste, EPA have removed all quantities that have both a
              "D" waste code and a RCRA listed waste code.  While over 400,000 tons of waste
              were reported'as listed and characteristic, the  data rarely reported the constituents

-------
Costs                                                                              Page 3-45

                              ,x                     '
              present in the wastestream. Consequently, EPA assumed that treatment by the
              listed waste standard would also treat all underlying constituents to required levels.
              EPA acknowledges that this lack of data may create a significant false negative; to
              that extent, the analysis may underestimate the true cost of the rule.

       •      When assigning treatment technologies for cost estimation purposes, EPA assigned
              nonwastewater, soil, and debris streams to thermal desorption technologies. While
              the Agency believes that thermal desorption may have future application to the
              treatment of RCRA wastes, it acknowledges that currently there are no permitted
              thermal desorption units in operation. Therefore, EPA conducted a sensitivity
              analysis to estimate the effect on treatment costs if thermal desorption were not
              available.

              To conduct the sensitivity analysis, EPA first determined the total tonnage of each
              waste form that had been assigned to thermal  desorption or to a combination of
              thermal desorption and other technologies (e.g., thermal desorption followed by
              stabilization)  (see Appendix C for current percentages). For soils, the thermal
              desorption category had been combined with soil vapor  extraction technologies
              because of similar unit costs and applicability.  Because  these wastes were never
              specifically assigned to one of the two specific technologies, EPA assumed that
              half would be treated by thermal desorption. EPA then selected alternative
              technologies to be used if thermal desorption were not available.  For
              nonwastewater and soil, EPA selected incineration, and for debris, EPA selected
              extraction. In cases where a treatment train had been assigned, EPA assumed that
              only the thermal desorption portion would change and the remaining elements
              (e.g., stabilization) would be unchanged.

              Using unit costs from the main analysis for thermal desorption and the alternative
              technologies (see Appendix D), EPA estimated the cost increase for each waste
              form. For nonwastewaters, the cost for treating the affected wastestreams

-------
Page 3-46
              increased from $21 million to $53 million; for soil, the cost increased from $13
              million to $30 million; and for debris, the cost increased from $2 million to $4
              million.  In summary, the total treatment costs increased from $37 million to $87
              million, or an increase of $50 million.

              This cost increase reflects the potential underestimate of costs if thermal
              desorption was not employed for treating these wastes. In addition, this sensitivity
              analysis shows what the costs of the rule may be immediately following
              promulgation of the rule (i.e., before thermal desorption capacity, or other less
              costly treatment,  comes on line).

Economic Impacts                                 ,                                  Page 4-1


                                       CHAPTER 4
          ECONOMIC IMPACTS OF PHASE H LAND DISPOSAL RESTRICTIONS

       The economic impacts of the rule are measured as the difference between the likely
expenses that result from regulatory compliance and the industrial activity that would continue in
the absence of regulation (i.e., baseline conditions).  EPA typically considers economic impacts
based on the private cost of regulation evaluated on a facility-specific basis.

4.1    ECONOMIC IMPACTS METHODOLOGY
       Economic impacts for facilities managing organic TC wastes were evaluated on a facility-
specific basis, limited only by the extent that data were available.  This economic analysis is based
on 20 of the 47 facilities for which costs were determined on a facility-specific level.  EPA
estimated the economic effects by comparing incremental annual compliance costs to two financial
measures: revenue, and cost of operations (i.e., cost and expenses).  The most recent financial
data available were obtained from Standard & Poor's Corporation Records, Dunn and
Bradstreet's Million Dollar Directory, and Disclosure Information Services.
       Since EPA believes that no costs will be associated with the treatment standards for coke
by-products in the proposed rule, no economic impacts will be associated with the regulation of
these wastes. Economic impacts of compliance for facilities currently land disposing chlorotoluene
waste were evaluated on a facility-specific basis. EPA estimated the economic effects by
calculating  the ratio of the incremental annual before-tax compliance costs to the value of
production. Baseline and compliance before-tax annualized costs were  srimated for each facility
using the unit costs, prices, and waste quantities presented in the cost analysis. Data on total
sales for facilities that generate chlorinated toluene wastes were obtained from Dun & Bradstreet

42    RESULTS OF THE ECONOMIC IMPACTS ANALYSIS
       For the 14 captive companies (i.e., companies with non-commercial or captive landfills that
receive the company's wastes) in the TC capacity database, only one company would have a ratio
of incremental compliance cost to cost of operations greater than one tenth of one percent; all
other facilities would experience even lower econqmic impacts. See Tables 4-1 and 4-2 for

results.  Note that Table 4-2 presents the logarithm of the ratio; in this way it provides an
estimate of the order of magnitude of the effect  For example, the ratio of revenues to
compliance cost for the first facility has a log of 5.07. That is, revenues are 5 orders of
                                                           j
magnitude, ~ 100,000 times, greater than the cost of compliance. Similarly, the ratio of
compliance cost to cost and expenses has a log of -4.99. That is, the compliance cost is 5 orders
of magnitude less, or 0.00001 times the non-regulatory cost and expenses.
       Since no costs are associated  with the treatment standards for coke by-products, no
economic impacts are expected.  Economic impacts for facilities that generate chlorinated toluene
wastes are calculated based on the before-tax annualized incremental costs. The results of the
analysis, however, are aggregated since the data used in the analysis are propriety.  Based on a
ratio analysis of incremental.cost to total sales, none of the facilities that generate these wastes is
expected to experience significant impacts as a result of the proposed rule.

43    LIMITATIONS OF THE ANALYSIS
       Both  the data used for this analysis and the methodologies developed have limitations.
The most important limitations are addressed below.                                        '

       •      Not all the facilities in the  TG capacity database, the primary data source for this
                                                                                         4
              analysis, make financial information publicly available.

       •      Five captive companies with public financial information have more than one
              facility; there is no way to determine economic effects at the facility level. Thus;
              our analysis is limited to company-wide economic effects. To the extent that
              companies cannot redistribute the cost of compliance among facilities, our analysis
              may not identify faculties with economic effects at the local level.

Economic Impacts                                                                    Page 4-5
              Financial data are based on the last year reported and may not accurately predict
              longer-term company results.

              EPA estimated the economic impacts of the proposed rule for non-commercial
              facilities. In attempting to determine costs associated with commercial facilities,
              EPA matched BRS data for generators sending waste off-site to commercial
              facilities identified in the TC Survey.  The results were ir conclusive because data
              from these two sources were inconsistent and left a large percentage of waste
              unaccounted for. Therefore,  due to data limitations, for the commercial facilities
              that receive waste from off-site generators, EPA did not look at cost pass-through
              scenarios to estimate if any generators would be affected by the proposed rule.

              No small businesses or entities were identified in the TC capacity database,
              however, they may be impacted by commercial  facility pass-throughs.  EPA did not
              examine this effect

               BENEFITS OF PHASE U LAND DISPOSAL RESTRICTIONS

       This chapter discusses EPA's analysis of the benefits to society associated with the Phase
II LDR final rule. While the RIA for the Phase H rule quantifies a number of benefits, there are
potential benefits attributable to the rule that are unable to be quantified at this time.  These
potential benefits are grounded in the basic premise of the LDR program, that the only
permanent solution to management of hazardous wastes is significant reduction of toxicity in such
waste through treatment  Such treatment offers benefits to human health and the environment
over the long-term.
       EPA quantified three types of benefits for the Phase n rule:

       •     reduction in human health risks via the ground-water pathway,

       •     reduction in human health risks via the air pathway, and

       •     potential positive effects on the value of properties near waste management
             facilities.

       In  addition, EPA's benefit analysis covers only TC wastes. These wastes dominate the
other newly regulated wastestreams covered by the Phase H LDRs in terms of volume and costs.
Moreover, the data needed to evaluate the Phase n rule benefits were more readily available and
of much higher quality for the TC wastes' attributes (e.g., concentration, volume) than for the
other Phase n wastes.

5.1    HUMAN HEALTH RISK REDUCTION — GROUND-WATER PATHWAY
       One of HSWA's primary LDR goals is protecting human health.  To that end EPA
analyzed human health risks posed by TC wastes under the baseline scenario, that is with no
LDRs in place, as well as under the post-regulatory scenario.  The difference in risks from the
baseline to the post-regulatory scenario is one measure of the benefit of the rule. The benefits
estimated in this analysis focus on the long-term benefits associated with the permanence of waste
treatment. However, this assessment is limited to benefits realized under average or reasonably
expected conditions.  It is not able to estimate the benefits associated with more extreme
scenarios, such as a catastrophic landfill containment system failure or karst aquifer settings.
Under these extreme cases, the benefits of the Phase n LDR would be greater.
       The fundamental concept underlying EPA's approach for assessing ground-water risk
reduction is that Subtitle C containment is completely effective in the short-term, i.e., over a
period of about 30 years after liner and cover installation.  During this period, no leachate is
released to ground water, and Subtitle C regulation achieves its goal of reducing risk to human
health and the environment Over the longer term, however, containment systems eventually
and, because the waste in the unit has not been treated, constituents are released to the
environment This release, and its resulting ground-water contamination, may not be detected by
owner/operators, and could continue unaddressed by corrective action, closure, or other programs.
This longer-term risk (i.e.', occuring in the future) would be reduced by the LDRs.

       5.1.1   Approach
       EPA used similar but slightly different approaches to calculate risks to hypothetical
individuals and population risks across all facilities. The approaches are described below.

Individual Risks
       EPA's basic approach involves the following seven steps:

 (1)   Analyze waste concentration data from the TC survey database to estimate waste
       concentrations.

-------
Benefits                                                                     .        Page 5-3


  (2)   In cases where respondents reported total waste concentrations, rather than Toxicity
       Characteristic Leaching Procedure (TCLP) concentrations, use the Organic Leaching
       Model (OLM) to estimate leachate concentrations.
                                                                                      \
  (3)   Calculate the mean concentration of each constituent at each facility, weighted across the
       volume of all TC wastes managed at that facility.

  (4)   Calculate the risk that would be posed by consumption of leachate, for both cancer and
       non-cancer effects, at each facility.

  (5)   Develop a set of dilution/attenuation factors (DAF) to represent the effect of fate and
       transport processes in a ground-water system.

  (6)   Portray the full range of waste concentrations, environmental settings, and exposure
       conditions at facilities managing TC wastes by dividing the distribution of risks posed by
       consumption of leachate by the DAF distribution to yield  a predicted risk distribution at
       exposure wells across all facilities.

  (7)   To simulate the post-regulatory scenario, reset the leachate concentration in Step 1 with
       the universal standard concentrations.  Replace the DAF distribution for Subtitle C
       facilities (from Step 5) with a DAF distribution for Subtitle D facilities, because the
       treated TC residues will not need to be managed as hazardous wastes.  Recalculate risks
       to estimate the incremental risk reduction between the baseline and post-regulatory levels.

       The following discussion is keyed to the steps listed above.

       Step 1. Develop concentration data from the TC survey to represent waste
concentrations. The TC capacity  database covers several hundred wastestreams, each containing
one or more constituents, disposed of at nearly 100 facilities. To  develop the analytical sample,

Page 5-4


EPA dropped wastestreams with insufficient data or not subject to regulation as TC
nonwastewaters. The following wastestreams were deleted:

       •      wastestreams that only include wastewater,

       •      wastestreams with no TC volume information,

       •      wastestreams that include listed wastes (F-, K-, P-, or U-codes),

       •      wastestreams with no useful constituent information,

       •      wastestreams that are nonwastewater and not regulated by Phase n,

       •      wastestreams that do not exceed TC levels for D018-D043.
 After these wastestreams were dropped, the final sample of facilities that disposed of TC
 nonwastewaters contained 36 facilities. Benefits from this set of facilities were extrapolated to the
 universe of facilities managing nonwastewaters, i.e., 47 facilities.
        EPA's guidance for conducting risk assessments1 calls for development of both a central
 tendency risk estimate and a high-end risk estimate.. The central tendency estimate is intended to
 produce an estimate that is based on most likely values of all component parameters. The high-
 end estimate is intended to correspond to the high-end portion of the risk distribution, i.e., it is
, based on conservative values for input parameters. For this RIA, one of the factors that is most
 important in determining risk is constituent concentration in the waste,  and there is considerable
 uncertainty in the concentrations reported in the TC Survey.  For this reason, the Agency
 developed central tendency and high-end estimates of ground-water risk based on varying the
 constituent concentrations in the waste.

       The central tendency and high-end estimates differ in two ways.

       •      One of the survey questions called for information on waste concentrations, and
              did not specify whether respondents should report bulk concentration or
              concentration in the TCLP extract.  Based on the concentration values and the
              units that were reported, it appeared that many respondents reported bulk (total)
              concentrations. For the central tendency estimate, EPA interpreted-based on the
              units and the concentrations that were reported—that some of the responses
              applied to bulk concentrations .  For the high-end estimate, EPA assumed that all
              responses are in terms of TCLP  concentration.

       •      The survey asked for average, minimum, and maximum concentrations. For the
              central tendency, EPA used average concentrations where they were reported, and
              maximum concentration divided by 2 otherwise. For the high end, EPA used the
              maximum concentration where reported, and average concentration otherwise.

Each of the two sets of waste concentration estimates were carried through the remaining steps of
the risk analysis (note that step 2 pertains only to the central tendency estimate).

       Step 2.  Where respondents reported total concentrations, rather than TCLP
concentrations, use the OLM to predict leachate concentrations. EPA assumed that the TCLP
accurately predicts long-term leaching behavior  of wastes in the environment, i.e., that the TCLP
leachate concentration is equal to the long-term average leachate concentration. For the central
tendency scenario, in situations where EPA believed that survey responses were probably in terms
of total (bulk) waste concentration rather than TCLP concentrations,  EPA used the OLM to
predict leachate concentrations. EPA has used  this technique in a variety of other applications,
including the delisting program and several other RIAs.  The OLM equation may be represented
as

where L is the leachate concentration [mg/I], C is the bulk waste concentration [rag/kg], and S is
the constituent water solubility [mg/!].
       Appendix G provides the calculated leachate concentrations for each constituent at each
of the sample facilities, under the central tendency scenario.

       Step 3. Calculate the mean concentration of each constituent at each facility, weighted
across the tonnage of all TC wastes managed at that facility.  EPA assumed that, at each facility,
all TC wastes would be managed in the same landfill unit, and that the average concentration for
the unit would be the weighted average across all of the TC wastes. Note that in some cases TC
wastes are co-disposed with other wastes; nevertheless, for purposes of this analysis, EPA did not
attempt to evaluate complex interactions with non-TC wastes.

       Step 4. Calculate the risk that would be posed by consumption of leachate, for both
cancer and non-cancer effects, at each facility.  EPA assembled values for oral toxicity from its
Integrated Risk Information System (IRIS), for both cancer and non-cancer effects. Using
standard assumptions for body weight (70 kg), water intake (2 liters per day), and exposure
duration (nine years), EPA calculated the cancer risk that would be posed by drinking undiluted
leachate at each facility.  For non-carcinogens, the Agency calculated the hazard  index, i.e., the
ratio of exposure dose to the reference dose.  Within each facility, EPA summed the cancer risk
across constituents, and the hazard index across constituents.  This yielded values for risk, at the
facility level,  prior to any accounting for fate  and transport processes.
       In general, for each facility, one constituent  dominated all others in terms of risk. Exhibit
5-1 presents the principal constituents posing cancer risk in the central tendency  baseline for each
of the 36 sample facilities.  It also provides their post-regulatory leachate concentrations (i.e.,  the
universal standard). Central tendency concentrations for all constituents are provided in
Appendix G.  Note that at 25 of the 36 faculties (70 percent), the risk-driving constituent is
benzene.  No other constituent appears more than twice as the principal risk-driver.  Exhibit 5-2

presents similar information for the constituents dominating non-cancer risk.  Only 16 of the 36
sample facilities had constituents contributing to non-cancer risks; the remaining 20 facilities were
assumed to have no non-cancer risks. At two of the 16 facilities, the non-cancer risk-driver was
an inorganic metal (e.g., nickel). At two other facilities, the risk-driver was an organic chemical
that was not regulated under the TC rule (toluene, ethylbenzene).

       Step 5. Use a dilution/attenuation factor (DAT)  to represent the effect of fate and
transport processes in a ground-water system.  In this step, EPA divided the facility risk by the
DAF distribution to yield a frequency distribution of predicted risks at exposure wells.  The DAF
distribution used in this analysis was determined by scaling the DAF distribution  used  in the TC
rule2  to reflect the effect of Subtitle C containment, after some level of system failure.
       There are several important timing assumptions that are implicit in the use of the DAF
distribution.  First, as previously mentioned, the  releases are assumed  to occur at some point in
the future when the containment systems fail; this  is likely to be at least 30 years after installation
of the cover and liner. Second, the approach assumes that the releases occur after ground-wa
monitoring and corrective action have ceased; otherwise,  these activities would be likely to reduce
the baseline risk at  most facilities.  Third, the DAF distribution was developed using a steady-state
model; the model predicts concentrations at a downgradient well,  assuming that there  is an
infinite source of contaminant in the waste. The model predicts equilibrium concentrations at the
well, i.e., concentrations after the constituent has had sufficient time to travel downgradient. The
time needed to attain this equilibrium can vary from months to millennia, depending on ground-
water velocity, distance to the exposure well, and the retardation factor of the contaminant (i.e.,
the velocity of the contaminant relative to the ground water that is carrying it). The benefit
analysis is oriented to long-term benefits; as this discussion makes clear, the baseline risks may be
posed over a period of decades to centuries. Nevertheless, for the TC rule the infinite source and
steady-state assumptions were deemed reasonable by the  Agency for purposes of regulating TC
constituents, and for the Phase n LDR RIA they are reasonable for estimating the potential
benefits due to related ground-water contamination in the long term.
   2This distribution is based on the facility, environmental, and exposure characteristics of municipal (Le., Subtitle'
landfills.                                                   .

       To account for the effect of Subtitle C containment (e.g., cover and liners), EPA assumed
that in any environmental setting, the DAF is inversely proportional to the infiltration rate.  For
the Corrective Action RIA, EPA developed a set of estimates of the effectiveness of caps and
liners. The Agency estimates that about 30 years after installation a Subtitle C cap is about 80
percent effective and a liner is about 85 percent effective. Thus, the liner would be the limiting
factor for net infiltration through the landfill. Using the figure of 85 percent effectiveness, the
percentage of infiltration passing through the landfill would be 100 percent less 85 percent, or 15
percent Thus, multiplying calculated infiltration by 0.15 would reflect the effect of Subtitle C
containment that is no longer at peak effectiveness. This approach assumes that  after about 30
years after the operating period ends, the owner/operator no longer inspects the cap; nor does
anyone replace or  repair the cap.
       The table below displays the upper quartile of the DAF distribution used  in this analysis,
including both the set of DAFs developed for the TC  rule (which addressed management of
wastes in Subtitle D facilities), and the adjusted set used for this RIA (i.e., the values from the
TC rule divided by a factor of 0.15 to account for the  effectiveness of a Subtitle C containme
system over the very long term). The set of DAFs used to simulate baseline conditions at Subtitle
C units are higher than those for the Subtitle D units, indicating a higher level of protection in
the Subtitle C units than in the Subtitle D units.

       Additionally, to estimate distributions of individual risks, EPA assumed that 23 percent of
the facilities have downgradient exposure wells. This is based on Subtitle C data from the

-------
Benefits          	             Page 5-11


Corrective Action RIA database,3 which covers facility-specific information collected for a
stratified random sample of 79 facilities. The data indicate that 23 percent of treatment, storage,
and disposal facilities had downgradient private or public wells in the direction of ground-water
flow.4  To account for this, EPA scaled its risk estimates by assuming that the DAFs apply only
at 23 percent of the facilities, and at all others there is no human exposure via ground water.

       Step 6. Portray the full range of waste concentrations, environmental settings, and
exposure  conditions at facilities managing TC wastes by dividing the distribution of risks posed
by consumption of leachate by the DAF distribution to yield a predicted risk distribution at
exposure  wells across all facilities managing untreated TC wastes. This step was conducted by
using SAS software to combine DAF and facility leachate risk distributions to generate a
nationwide distribution of ground-water risks associated with facilities managing TC
nonwastewaters.  (See Exhibit 5-3 for a graphic representation of this step).  The DAF
distributions were not sampled randomly (e.g., with a Monte Carlo approach) but rather at
predetermined intervals, i.e., at two percent intervals across the entire frequency distribution.
These  were combined with each  of the discrete facility-specific leachate risk values to produce
1,800 risk estimates (i.e., 36 leachate risks divided by 50 DAFs each).  These values were used to
generate an intermediate individual risk output  distribution covering the full range of DAFs and
waste characteristics reported at  faculties.  Note that these individual risk distributions represent
risks to a  hypothetical receptor, and not to real people.
       As discussed under Step 5, the Agency assumed that only 23 percent of the facilities were
expected  to have down-gradient wells.  However,  the facilities without down-gradient exposures
(i.e., 77 percent) could not be identified on a site-specific basis because the available data on
downgradient wells provided only the overall percentages. To account for this when calculating
probability distributions for individual risk, EPA assumed that the intermediate distribution
derived from all 36 faculties applied only to the upper 23 percent of the final distribution. In

other words, all individual risks below the 77th percentile of the Goal distribution were assumed to
be zero (because of no exposures), the first percentile value from the intermediate distribution
corresponds to (approximately) the 78th percentile of the final distribution, and the 100th
percentile of the intermediate distribution would be equivalent to the 100th percentile of the final
distribution.
              t

       Step 7. Using the same framework as for the baseline calculations, develop a
distribution of risks for facilities managing TC wastes for the post-regulatory scenario. The
post-regulatory scenario assumes that all hazardous constituents will be treated to universal
standards, and that the wastes will be disposed of in Subtitle D landfills following treatment.
       EPA assumed that the post-regulatory leachate concentration would be equal to the
universal treatment standard (UTS).  For each constituent, EPA determined the UTS. If the
UTS was lower than the baseline concentration, the UTS was used as the leachate concentration.
These post-regulatory leachate concentration values were divided by their toxicity benchmarks and
summed by facility, as described earlier for step 4, to calculate risks that would correspond to
drinking leachate at each facility.
       These  risks were then combined with a DAF distribution to generate a distribution of risks
at exposure wells.  As discussed earlier, the DAF distribution for the baseline  analysis was
calculated by adjusting the DAF distribution used in the TC identification rule to reflect the
effect of Subtitle C containment. Because post-treatment disposal would not be in a Subtitle C
unit, EPA used the TC rule's DAF distribution when calculating post-regulatory exposure
concentrations.
       For the post-regulatory scenario, there is no difference in the central tendency estimate
and the high-end estimate, i.e., they both use the same sets of waste concentrations.

Population Risks                                                                           .
       EPA's approach for estimating  population risks involves nine steps:

(1-5)  Develop concentration data from the TC survey to represent waste concentrations and
       calculate the risk posed by consumption of the leachate, and  use a dilution/attenuation

       factor (DAF) to represent the effect of fate and transport processes in a ground-water
       system.  These steps are identical to the first five steps used to calculate individual risks.

(6)    Calculate the population exposed to ground water at each of the 36 facilities.

(7)    Integrate the risk level over the exposed  population and DAF distribution to calculate
       population risks for each facility.

(8)    Calculate total population risks for the affected universe of facilities.

(9)   . Calculate total population risks under for the post-regulatory scenario and develop
       incremental benefit estimates for the rule..

       As noted, the first five steps are identical to those use to calculate individual risks. The
following discussion details steps six through nine.

       Step 6.  Calculate the population exposed to ground water at each of the 36 facilities.
Although EPA bad population density data for the Phase n LDR sample facilities, data on
populations exposed to ground water were not available. However, EPA had both population
density and exposed population data for sample facilities included in the Corrective Action RIA.
EPA combined these data sources, as  shown in Exhibit 5-4, to estimate the population exposed to
ground water at each facility, using the following three steps:

       (1)     Using data in the GEMS database, EPA calculated the local (i.e., within 3 km)
              population density for each of the 36 facilities.

       (2)     Using data collected for the Corrective Action RIA, EPA examined the
              relationship between the local population density and the population exposed to
              ground water. For each of 52 facilities included in the Corrective Action RIA
              sample, EPA determined the local population density within 2 km  (population

               density data was not available to 3 km) and the total exposed population. The
               total exposed population was determined by identifying all public and private wells
               located in a 90 degree sector in the direction of ground-water flow within a two
               mile radius of the facility. For many faculties, the exposed population was zero.5

               Based on these data, EPA determined an average ratio of exposed population to
               total population within the 90 degree ground-water exposure sector for low-density
               (less than 1,000 people per square kilometer) and high-density (more than 1,000
               people per square kilometer) settings. For each case, the average exposed
               population was  calculated by averaging all exposed population values (including
               zero exposure values).  Similarly, the average total population was calculated by
               averaging the facility-specific populations (calculated as the product of the density
               and the sector area). For low-density settings, EPA estimated that the population
               exposed via ground water would be approximately 0.4 times the total population.^
            '   For high-density settings, EPA estimated that the population potentially exposd^H
               via ground water would be approximately 0.05 times the total population. The
               exposed population in high-density areas is less than in low-density areas because
               these areas are  more likely to use public water supplies drawing from sources
               sufficiently distant from the contaminant source to not be impacted.

       (3)    . EPA multiplied the facility-specific total populations within the ground-water
               exposure  sector for the 36 sample facilities by the exposure ratios to estimate the
               hypothetical exposed population for each facility.

       Step 7. Integrate the risk level over the exposed population and DAF distribution to
calculate population risks for each facility.  For all facilities, EPA sampled the DAF distribution
over 100 intervals (i.e., at each percentile) to generate a series of 100 DAF values.  Then, for
each facility, EPA multiplied the leachate risk level by the DAF and the incremental population
   *The method for estimating individual risk accounts for situations where there are. no downgradient wells by adjusting
the DAF distribution (see step 5, above). For estimating population risks, facilities with no downgradient wells are
included in the computation of average well-using population density.

(i.e., l/100th of the total population) and summed over all increments to calculate the total
population risk level.  (See Exhibit 5-5 for a graphic representation of this step).

       Step 8. Calculate total risks for the affected universe.  EPA estimated cancer and non-
cancer effects for the affected universe based on the facility-specific risk levels, using the
following approach:

       •      For cancer risks, EPA first summed the 36 facility-specific values. This value was
              then multiplied by (47/36) to scale from the 36 modeled facilities to the 47
              facilities in the affected universe.

       •      For non-cancer effects, EPA examined the DAF-adjusted  ratio of the exposure
              concentration to the appropriate threshold value for each of the 36 facilities. If
              the ratio exceeded unity, EPA assumed the entire population to be exposed;
              otherwise, EPA assumed the exposed population to be zero.  EPA then summed
              these populations and scaled up the total to represent 47 facilities.

       Step 9. Calculate risks for the post-regulatory scenario and calculate incremental
benefit estimates.  Using the same approach used to, calculate baseline risks, EPA calculated post-
regulatory risks using the same assumptions used for the individual-risk analysis. Note that
because the effectiveness of containment is assumed to be less in the post-regulatory case
(Subtitle D) than in the baseline case (Subtitle C), post-regulatory risks may actually rise if
treatment does not significantly decrease the leachate concentration. The post-regulatory risk was
then subtracted from the baseline scenarios to estimate the incremental benefit

       5.1.2  Results
       This section presents results for the baseline risks  (under both central tendency and high-
end assumptions) and the post-regulatory scenario.  For each case, distinct results for individual  •
cancer and non-cancer risk are presented. The section concludes with population risk estimates.

Individual Risks

       Exhibit 5-6 presents the estimates of the baseline and post-regulatory individual cancer
risk across all facilities.  The results are presented in terms of a cumulative frequency distribution
indicating the percentile level associated with an individual risk level across all facilities.  These
individual risk values represent the 1,800 different combinations of facilities and DAFs that were
statistically combined for this analysis, which have been compressed over the top 23 percent of the
distribution  to account for facilities with no downgradient wells. As the exhibit shows, the high-
end baseline risk estimate is between one and two orders of magnitude higher than the central
tendency estimate across the distribution. About ten percent of the individual risk values indicate
baseline  lifetime excess individual cancer risk exceeding 10"6 under high-end assumptions, with
almost Gve percent exceeding 10"4. About six percent of the individual risk values exceed  10"6 in
the baseline using central tendency assumptions, including about two percent which exceed 10*4.
In the post-regulatory case, about five percent of the individual risk values indicate excess cancer
risks above  10"*, and about one percent of the risk values exceed 10*4. A single-value (i.e., not a
distribution) estimate for central  tendency risk may be estimated as the 50th percentile of the
central tendency curve, i.e., zero  because most facilities are not expected to have downgradient
wells.  Similarly, a single-value estimate for high-end risk may be estimated as the 90th percentile
of the high  end curve, i.e., approximately 2.0 x 10"7.
       Exhibit 5-7 presents the estimated baseline and post-regulatory non-cancer risk.  Using
central tendency assumptions, the 99th percentile baseline exposure level is less than the
reference dose. Under high-end assumptions, about two percent of the distribution exceeds a
hazard index of unity, indicating the potential for adverse non-cancer effects. Post-regulatory
non-cancer  risk, however, is insignificant.
                                                                     i
Population Risks

       Population cancer risks are presented in Exhibit 5-8. The estimated baseline population
cancer risk is 0.24 cases per year for the central tendency scenario. The post-regulatory
population cancer risk is about 0.022 cases per year.  In other words,  the rule reduces 0.22 cancer

cases per year with respect to the central tendency baseline, that is, 92 percent of the baseline
cancer cases. Note that for some specific facilities, the post-regulatory risks are higher than in the
baseline. This is because the reduction in risk effected by treatment was less than the increase in
risk associated with Subtitle D, rather than  Subtitle C, disposal.
       Population risks for non-cancer effects are presented in Exhibit 5-9. Two of the 36
facilities had exposure-to-threshold ratios above unity in the baseline case, resulting in a total
scaled population of 2,038. In the post-regulatory scenario, however, no facilities exceeded a ratio
value of unity.  Therefore,  all of the non-cancer baseline risk is eliminated.

5.2    HUMAN HEALTH RISK REDUCTION—AIR PATHWAY
       Constituents  contained in TC waste, soil, and debris may be emitted to air through
volatilization or dust entrainment. Reducing the concentrations of TC constituents according to
the Phase II LDR treatment standards would significantly reduce the potential for air emissions,
and the risks posed by those air emissions.  The goal of the air pathway risk analysis is to
characterize baseline risk and the reduction in baseline risk resulting from the Phase n LDR rule.
This analysis focuses on the benefits in average or expected situations.  In more extreme cases
(e.g., catastrophic meteorological conditions or emissions from explosions) the benefits of the rule
would be greater.

       5.2.1 Approach
       The Agency's approach employed seven steps:

  (1)   Develop bulk waste concentration data from the TC capacity database to represent waste
       concentrations.

  (2)   In cases where respondents  reported TCLP concentrations, rather than bulk
       concentrations, use the Organic Leaching Model (OLM) to back-calculate bulk
       concentrations.

  (3)   Calculate the mean concentration of each constituent at each facility, weighted across the
       volume of all TC wastes managed at that facility.

  (4)   Calculate the unit area where TC wastes are managed.

  (5)   Estimate emissions due to volatilization and dust entrainment for each constituent at each
       facility.

  (6)   Using an integrated atmospheric dispersion/exposure/risk model, evaluate atmospheric
       transport for each constituent Estimate exposures for each constituent at a series of
       downwind points corresponding to potential exposure locations.  Calculate individual and
       population cancer and non-cancer risk.

  (7)   Simulate the post-regulatory scenario.

       The following discussion is keyed to the steps listed above.

       Steps 1 through 3. Calculate constituent concentrations.  The approach for these steps is
essentially identical to that described for the ground-water risk analysis in section 5.1.1, except
that EPA used total concentrations rather than TCLP concentrations in the air analysis.  Exhibit
5-10 presents the facility-averaged waste concentrations for each constituent at each facility, for
both the baseline and post-regulatory scenarios.

       Step 4. Calculate the unit area where TC wastes are managed. EPA assumed that (1)
nonwastewater TC wastes are managed in landfills, (2) landfills have a working depth of 4 m, and
(3) the working area can be calculated by dividing annual waste volume (in m3) by 4 m. Unit
area is an input to the emission calculations and dispersion calculations in steps 5 and 6,
                                                                            \
respectively.

       Step 5. Estimate emissions due to volatilization and dust entrainment for each
constituent at each facility. EPA used the volatilization algorithms first described  in Hwang and
Falco (1986)6 and subsequently adopted in the Risk Assessment Guidance for Superfund
(RAGS) and MMSOILS model.  This volatilization model is based on a mass balance of the
chemical that is transported by diffusion in the vapor phase where the vapor phase and soil
adsorbed phases of the chemical are assumed to be in equilibrium. The model is. generally used
for uncovered sites where the contaminant is adsorbed to the soil. The emission rate, N, is
calculated as the average emission rate over a time interval, from  time equals 0 to t, as

                                       vW      Kd   XF1
       The effective diffusion parameter is calculated as

       The definitions and values of parameters are as follows:

       Cs      =  adsorbed chemical concentration in soil (1,000 rug/kg)
       DJ      =  diffusion coefficient of compound in air (0.1 cm2/s)
       H      =  Henry's law constant (0.2294 dimensionless)
       Kg     =  soil-water partition coefficient (7.0 ml/g)
                 (using fog of 0.02 and Y^ of 347.6664 ml/g)
       N      =  mass flux (g/s/cm2) (calculated)
       R      =  gas constant (8.2E-05 [atm m3]/[mol K]),
       t       =  time (sec) (scenario dependent)

       To predict dust entrainment from wind erosion and vehicular traffic, EPA also used
approaches adopted for the MMSOILS model.7  The equation used to represent the wind
erosion of inhalable particulates, PM10, is
PM10 .   = 0.036  (l-VG )
                          wind
                                                    w
                                                   —    F (x)  ASXF2
                                                   U
                                                     t
The empirical equation used to represent the emission factor for particulates, E^ (kg/VKT),
from an uncovered landfill per vehicle kilometers traveled per hour, VKT, is
                    Emv  = 0.36 (1.7) JL  x     ()°-7  ft0-                          (5)
                      mv        •     ' 12    48 ^2.T    V       365
The average hourly emission due to vehicle traffic is then estimated as
                                    =  1,000 (glkg) *EmvxVKT                      (6)
Definitions of parameters used in these equations follow:

  AS         = area of site (hectares),,
  E,^       = emission factor from an unpaved road per vehicle- kilometer of travel (kg/VKT),
  F(x)       = plotted function (dimensionless),
  PM10wind  = emission rate for inhalable particulates, less than 10 urn, (g/hr), from wind
                erosion
  PM 10veb   = emission rate for particulates less than 10 urn, (g/hr), from vehicle traffic
   7The approach for wind erosion is taken from Cowherd, C. et al., Rapid Assessment of Exposure to Paniculate
Emissions from Surface Contamination, prepared for EPA, Office of Health and Environmental Assessment, 1985. The
source of the approach for dust from vehicular traffic (e.g., trucks unloading washes on a landfill area) is CompUati
Air Pollutant Emission Factors, Volume 1: Stationary Point and Area Sources, 4 edl, USEPA/OAQPS,  1985.

  pe         = number of days per year with at least 0.01 inches of precipitation (daysfyear),
  S          = mean vehicle speed (km/hr),
  s          = percent silt content of road surface (percent),
  uw         = mean annual wind speed (m/s),
  ut         = threshold velocity at 7 m height (m/s),                .          ,
  VG        = fraction of contaminated surface with vegetative cover (dimensionless),
  VKT       = average vehicle kilometers of travel per hour on unpaved road, (# veh. x km/hr),
  W         = mean vehicle weight (Mg),
  w         = mean number of wheels per vehicle (#),
  x          = dimensionless ratio (x=0.886 ut/u),
  XF2       = units conversion factor (104 m2/ha).

       EPA employed a mass balance check to assure that, on an annual basis, the mass emitted
through volatilization and paniculate entrainment does not exceed the mass disposed of. The
Agency limited emissions due to volatilization based on a simple vapor pressure constraint.
Specifically, EPA back-calculated the emission rate that would be sufficient to produce vapor
saturation given an air flow corresponding to an assumed mixing height of 2 cm, wind velocity of
2.25 m/sec, and unit width calculated as the square root of the unit area. This rate was never
limiting; even if the mixing height is reduced to 2 mm, it would limit emissions for only two
constituent/facility combinations.

       EPA used concentrations from the TC Survey database as input for its calculations on
paniculate entrainment EPA assumed that all wastes are similar to soils in terms of properties
relevant to volatilization and wind erosion.

       Step 6. Evaluate atmospheric transport, exposure, and risk.  For  this step, EPA relied
on GAMS (the Graphical Exposure Modeling System [GEMS] Atmospheric Modeling Subsystem)
to evaluate atmospheric transport for each constituent, estimate exposures  for each constituent at
a series of downwind points corresponding to potential exposure locations, and calculate
individual and population cancer and non-cancer risk. The following discussion summarizes the

-------
Page 5-36
approach for this step; for a more detailed discussion of GEMS and GAMS, along with an
example of the input specifications and model output for a sample facility, see Appendix H.
       GAMS provides an automated link between the location of a facility and the meteorologic
and population data sets needed to estimate atmospheric dispersion and population risk,
respectively.   It  is based the Industrial Source Complex Model - Long Term (ISCLT) and other
widely accepted and frequently applied atmospheric dispersion and risk assessment models.
GEMS is housed on the VAX Cluster of computers at EPA's National Computer Center (NCC).
       GAMS estimates annual average concentrations, annual exposure, and lifetime  and annual
cancer risk.  For this RIA, EPA modeled the source as a square-shaped area source, with
estimated site-specific area as calculated  in step 4.  Other methods and assumptions include

       •      Meteorological data. EPA used the facilities' zip codes, as reported in the TC
              Survey, as the basis for specifying facility locations. GAMS contains data on the
              centroid of each  zip code; for this analysis, EPA assumed that facilities are loca
              at these centroids.  The model can identify all nearby "stability array" meteoroL
              stations for which the National Oceanic and Atmospheric Administration has
              logged data. EPA  used meteorological data from the closest available station.
              The data cover wind speed, wind direction, atmospheric stability, and related
              factors.

       •      Exposure assumptions.  The Agency assumed that the receptor height is 2 meters
              above ground level. For most other exposure-related factors, EPA employed the
              default assumptions used  in the model's exposure algorithms, i.e., body weight is 70
              kg, inhalation rate is 20 m3/day, exposure occurs 24 hours per day, indoor air
              concentrations are  equal to outdoor concentrations, and receptors are exposed for
              the full duration  of their lives (70 years).  EPA calculated exposures for each
              constituent at each facility.

       •      Toxicity data. For  carcinogenic constituents, EPA combined the estimated
              exposures with cancer potency factors to calculate cancer risk (as a probability).,

-------
Benefits	.                  Page 5-37


              For non-carcinogens, EPA calculated the ratio of the predicted dose to the
              reference dose (RfDs) — the result is termed the "non-cancer risk ratio."  For each
              site, the Agency summed the cancer  risk across all carcinogenic constituents, and
              the non-cancer ratio across all non-carcinogens.

       •      Site-specific population data. The Agency used the GEMS Geodata Handling
              procedure to obtain 1990 census data within the area circumscribed by a radius of
              50 kilometers from the facility centerpoint  The 50-km circle is subdivided into
              160 sectors, as defined by 16 wind vectors and 10 distances from the source.
              GAMS calculates the mean annual average concentration for each sector, and, by
              using the exposure assumptions and risk calculation method described above,
              estimates the individual risk for receptors in the sector.  The model stores
              information on the geographic centroid of each census tract; the entire population
              of that tract is assumed to bear the risk for the air modeling sector in which the
              census tract centroid is located.  In this way, EPA calculated the estimated cancer
              cases (incremental to the background cancer rate  due to other causes) for each
              census tract, and summed across these  tracts for each facility. For non-
              carcinogens, EPA tabulated, for each facility, the number of people with a non-
              cancer risk ratio exceeding one.

       •      High-end individual. GAMS employs an algorithm to identify the location with the
              highest annual average concentration within the modeling boundary (i.e., within 50
              km from the source).  For ground-level, ambient-temperature sources such as the
              landfills modeled for this RIA, this distance tends to be  on the order of 20 to 40
              meters from the source8, along the wind vector where the atmosphere is stable
              most  frequently.  EPA calculated the individual risk for  a hypothetical receptor at .
              this location for each facility.
   'The reason it is not closer is that the receptor height is assumed to be 2 m above the ground.

-------
Page 5-38
       EPA extrapolated the risks from the 35 (facility-specific results are presented for only 31
facilities because 4 of the facilities were determined to not be generating affected wastes in 1995)
modeled facilities to the universe of 47 facilities managing TC nonwastewaters and soils.
Uncertainty is introduced by this extrapolation; the risks at the 12 facilities that were not modeled
may be higher or lower than risks  at the facilities that were modeled.

       Step 7.  Simulate the regulatory alternatives.  In this step, EPA reset the bulk
concentrations in steps 1 through 3 with concentrations that would leach at the universal
treatment standard concentrations. EPA then recalculated risks; the incremental risk reduction
between the baseline and the post-regulatory scenario is the human health benefit, for the
atmospheric pathway, for the regulation.

       5.2.2  Results
       Exhibits  5-11 and 5-12 provide results  for the air pathway, for the baseline and post-  ^^
regulatory scenario.  In the baseline, 26 of the 35 modeled faculties (74 percent) have individil^B
cancer risks exceeding 10"6 at the high-end individual location:  16 have risks between 10"6 and 10*
4, and 10 facib'ties have risks greater than 10"4. The highest value is 5 x  10"3.
       For  the high-end individual location, the non-cancer risk ratio exceeds one at only one
facility.
       The final regulation effectively reduces individual cancer risk. At the high-end individual
location, eight facilities have risks  exceeding 10"6; the highest individual risk is 8 x 10*6. Doses of
all non-carcinogens are well below reference doses.
       Exhibit 5-13 presents total population  risks for cancer and non-cancer affects, and Exhibit
5-14 presents facility-specific cancer risks. As with the high-end individual, the regulation
effectively reduces virtually all of the baseline population risk of cancer and non-cancer effects.
       The Agency conducted some sensitivity analysis on emission rates, which directly affect
estimated risks.  Based on the work EPA did on the proposed and final rule RIAs, the Agency
has determined  that estimated risks are more sensitive to underlying estimates of volatilization
release rates. The emission rate for volatilization far exceeds the rate for release via dust

entrainment for almost all constituents in this analysis, and thus the sensitivity analysis focuses on
volatile emissions.
       Subtitle C permits usually require daily cover for land disposal units. The analysis assumed
all units were uncovered, overstating the rate of volatilization. On the other hand, EPA also
assumed that the waste is deposited in the landfill only one time per year, at the beginning of the
year, rather than being replenished periodically. In the volatilization algorithm used in this
analysis, the time-weighted average emission rate is inversely proportional to the square root of
the duration of the averaging period.  In other words, the shorter the time period of interest, the
higher the emission rate for that period, all else being  equal. The assumptions on cover and
frequency of waste deposition interact in a complex way, and to some extent may offset each
other.
       Exhibit 5-15 shows the relationship between volatilization rate and (1) the frequency with
which waste is placed and (2) the duration for which the waste is left uncovered. The first row
shows the conditions used in the analysis (i.e., waste deposited once per year and left uncovered);
subsequent rows show how emissions would vary under different assumption!; on how frequently
the waste is placed and how lor., waste is left uncovered  For purposes of calculating relative
emission rates in this table, emissions while the waste is covered are assumed to be zero.  Note
that this sensitivity analysis assumed that the active area of the waste disposal unit does not

assumption becomes lass and less realistic, as the depth of waste would get thinner and thinner.

       In the TC Survey, EPA did not collect information on the frequency of waste deposition
and the duration waste is uncovered. As the table shows, as the waste is placed more frequently
and left uncovered for longer periods, the emission rate is higher and thus the baseline risks (and
benefits of the rule) are higher. If waste is placed every operating day, and is left uncovered for 4
to 8 hours (or longer), then the baseline risks and benefits would be higher than those described
earlier in this section. At a waste placement frequency of about once per week,  if the wastes are
uncovered for about 4 to 8 hours, the baseline risks are roughly the same as those described
above. If the wastes are placed less frequently, (e.g., quarterly or monthly), then the baseline
risks and benefits may have been overstated in the results described above.
       In addition to the general  analytic limitations described in section 5.4.2, one caveat 'is
particularly important for the sensitivity analysis on volatile emissions. The algorithm used to
estimate emissions is based on an  assumption that there is an infinite depth of contaminated soil
which acts as the source of volatilization. Holding the area of the waste management unit and
the volume of waste annually deposited in the unit constant, as  the frequency of waste deposition

increases, the layer of contaminated waste becomes thinner^and thinner, and .the infinite depth
assumption becomes less and less valid.  As a result, applying the algorithm to the scenarios with
frequent waste deposition (e.g., 250 times per year) is a less valid application than those for less
frequent waste deposition, and the estimated emission rates for the high-frequency scenarios may
overstate emissions.

S3    EFFECT OF LDRs ON PROPERTY VALUES
       This section discusses another potential benefit of treating toxicity characteristic (TC)
nonwastewaters.  Treating these wastes may allow them to be disposed of in Subtitle D (non-
hazardous) waste facilities rather than in Subtitle C (hazardous) waste facilities, and may reduce
the total number of hazardous waste sites required. Both kinds of waste sites are disamenities;
they impose costs on the surrounding residents, including health risks and nuisance effects like
noise, odor, and traffic. However, since hazardous waste sites are perceived by the public as
riskier than non-hazardous sites, the costs they impose are higher. Replacing hazardous waste
sites with non-hazardous waste sites would then produce a benefit for residents, near these si
       EPA has conducted a preliminary analysis of these potential benefits, described in this
section.  The costs imposed by waste sites have been estimated in numerous studies through  their
effect on surrounding residential property values.  Property values reflect the effects of
surrounding amenities  and disamenities and can be used to estimate the values of these effects to
residents. EPA has based its analysis of the potential property value benefits of TC waste
treatment on a review  of these studies.

       53.1   Methodology
       The studies EPA reviewed use hedonic analysis to estimate the effect of waste sites on
property value.  The premise of hedonic property value analysis is that housing prices are
determined by a range of attributes of the house,  its site, and its neighborhood. The technique •
uses multiple regression analysis to determine the separate  effects of each factor on housing price.
If one attribute included in the analysis is an environmental characteristic, the effect of that
characteristic on price  can be used to estimate the benefits from changes in the level of that
characteristic (e.g. a change in the level of air pollution or in the distance to a waste site).

-------
Benefits	'	Page 5-45


       One of the attributes captured in a bedonics study is how the level of potential personal
health risk affects housing prices. In capturing health risk as an attribute that affects housing
prices, the study double-counts potential benefits quantified for health risk from the ground-water
and air pathways. Therefore, the study presented in the RIA is a supplemental benefits analysis,
not meant to be added to other beneGts quantified for the Phase n rule.
       Many analyses exist on the.effect of waste sites on property value. Some have studied
hazardous waste sites and some non-hazardous waste sites. However EPA is aware of only one
study, by Thayer et al.,9 that explicitly compares the effects of these two kinds of sites. EPA has
therefore based its analysis on this study.  Thayer et al. use the hedonic method to determine the
effect of distance from hazardous and non-hazardous waste sites on housing purchase prices.
They use a data set from Baltimore, Maryland, containing 2,323 observations of housing
transactions.  Data on waste facilities are from EPA records of treatment, storage and disposal
facilities.  The authors first estimate the effect of all waste sites on housing value, measured in
dollars per mile. They then use dummy variables to distinguish the effects of hazardous and  non-
hazardous waste sites.
       The basic results of the Thayer study are comparable to those of other studies. As
distance from any waste site (hazardous or non-hazardous) increases, housing value increases, all
other factors held constant.  Thayer et al. estimate an increase of $1,300 to $1,700 per mile
(depending on the functional form of the regression equation).  Other hedonic property value
studies that EPA reviewed showed estimates in the range of $2,000 to $5,000 per mile for
hazardous and non-hazardous waste sites. Given the inherent variation in the results of bedonic
property value studies, Thayer et al.'s findings are similar to those of other authors. The fact that
they are  somewhat lower than the other studies surveyed suggests that EPA's use of the Thayer
study may yield conservative estimates of the property value benefits  of hazardous waste
treatment
       EPA defined a specific scenario to evaluate the potential benefits of treating TC
nonwastewaters. Using information from the TC Survey, EPA identified 47 facilities expected to
generate TC nonwastewaters, soil and debris in 1995.  EPA eliminated the 17 commercial facilities

 (including CBI facilities) from this group, assuming that commercial facilities would continue to
 manage a variety of wastes, including hazardous wastes.  The remaining 30 facilities were
 industrial sites, likely to be managing fewer wastestreams on site.  For the purpose of estimation,
 EPA assumed that each of these 30 Subtitle C sites would be replaced with or convert to a
 Subtitle D facility. In effect, this approach assumes that the Thayer et al. study's hazardous waste
 facilities can be equated with Subtitle C land disposal facilities.
        The results of the Thayer study suggest that, for each owner-occupied house within a one-
 mile radius of a facility, replacing the Subtitle C site with a Subtitle D site would result in a
 benefit of $517 dollars.  The mean value of houses in the study sample was $105,600, so this
 benefit is equivalent to 0.49 percent of the Value of each house.  Using U.S. Census Bureau
 data,10 EPA estimated the value and density (i.e., houses per square mile) of owner-occupied
 houses in the region in which each site is located. From these data, EPA calculated the expected
 number of houses within one mile of each site, the expected benefit per household for each site,
 and total benefits for each site.  For example, one facility in the TC Survey is located in Port
 Arthur, Texas.  EPA estimates that the average density of houses in EPA's  Region VI is 425
 per square mile, or 1,335 houses within a circle with a one-mile radius. An estimate of the
 average value of a house in Region VI is $72,000; 0.49 percent of this value (the expected benefit
 per household) is $350. Thus, the total estimated benefit for this facility is  about $470,000. The
 sum of benefits across all 30 sites produced an estimate of the total property value benefit of
 treating the TC wastes.

        53.2   Results
        Exhibit 5-16 shows the results of this preliminary analysis. EPA estimates benefits per
 house of TC waste treatment ranging from $320 to $450 for houses near the 27 facilities, and
 benefits per facility ranging from $470,000 to $1.1 million.  The total benefits, summed across
 facilities, are estimated to be about $20 million (1993 dollars).

5.4    LIMITATIONS OF THE ANALYSIS

       This analysis is subject to many limitations, some of which tend to understate benefits,
others to overstate benefits, and some introducing uncertainty, but having no clear bias either
way.  Below, EPA lists some of the principal limitations of the analysis, and notes the likely
direction of bias where it is known.                      .

       5.4.1   Ground Water Risk Analysis

       Factors that overstate benefits:

       •      The DAF distribution used to estimate baseline risks was determined by beginning
              with the Subtitle D DAF distribution derived for the TC rule and adjusting it to
              represent a Subtitle C landfill with some degree of failure.  The failure
              assumptions used simplify an extremely complex set of phenomena and have the
              effect of applying a scaling factor to the DAFs. EPA considers it likely that the
              assumptions tend to underestimate the true effectiveness of Subtitle C
              containment. This assumption tended to overestimate the baseline risks, while the

-------
Page 5-48
              post-regulatory risks were not affected. Thus the total ground-water benefits were
              probably overstated.

       •      The infinite source and steady-state assumptions used to develop the original
              DAFs for the TC rale are conservative.  In reality, there may not be sufficient
              mass of constituent to act as an infinite source of contaminant. (A related point is
              that although the Agency did provide a mass balance check within the air risk
              pathway, it did not design the analysis to produce an inter-media mass balance
              check, i.e., it did not constrain mass so that the sum of air emissions and leachate
              releases must be less than the total mass of constituents disposed). Moreover, it
              may take centuries or millennia to attain equilibrium concentrations in a ground-
              water system, so the baseline risks may not occur until some point in the very
              distant future.
       •      The approach does not account for ground-water monitoring and corrective
              in the baseline. Existing regulations require that hazardous waste land disposal
              units conduct monitoring during the operating, closure, and post-closure periods.
              If containment systems fail while the monitoring is underway, and contamination is
              detected in ground water, this would trigger corrective action. The corrective
              action program would reduce risks, thus reducing the baseline risk level.  Thus, the
              benefits of the LDRs are overstated to the extent that the baseline risks  are
              reduced by corrective action.

       •      The approach does not take into account the effect of taste or odor thresholds, or
              water supply monitoring, which can alert receptors to the presence of
              contaminants and can lead to a halt in exposures. Therefore, the approach
              calculates risks for cases where exposure is unlikely to occur (i.e., the contaminant
              would be detectable by routine public water supply monitoring, and so the water
              would not be consumed).  This effect will be more significant in the baseline case
              because the concentrations are higher.  Therefore, the baseline risks may tend

-------
Benefits                                                                            Page 5-49


              be overestimated and the approach may tend to overestimate the benefits of the
              rule.

       •      Approximately 72 percent of the estimated ground-water population cancer risk
              comes from a wastestream that is approximately 95 percent PCBs.  As PCB
              isomers have a high soil-water partition coefficient, and thus cannot be expected to
              migrate any appreciable distance in ground water, the use of a generic DAF (i.e.,
              not a constituent-specific DAF) would result in an over-estimation of the benefits
              for this wastestream, and thus for the rule. However, the Agency does have
              reason to believe that PCBs migrate in soil when they are in the presence of
              solvents, and the remaining five percent of this particular wastestream does contain
              solvents.

       •      The central tendency estimate for the groundwater pathway has been overstated by
              employing an assumption of two liters per day rather than using 1.4 liters per day.

       •      The DAF distribution used in the RIA was not mathematically corrected to extend
              from the one mile  distance used in the TC analysis to the two miles used for this
              analysis. Therefore, EPA performed a sensitivity analysis reanalyzing the ground-
              water risk, considering only wells within a one-mile radius.  The alterations and
              results of this analysis are provided in Appendix K of the RIA. In summary, the
              revision changed the central tendency cancer cases per year from 0.22 to 0.18, and
              changed the non-cancer exposed population from 2,038 to 1,136.

       Factors that understate  benefits:

       •      One assumption in estimating the post-regulatory risks was that the leachate
              concentration could be represented by the universal  standard for each constituent.
              Because the universal standard represents a maximum allowable concentration in
              the post-regulatory case, it is  possible that safety factors in the treatment process

-------
Page 5-50
9eyj^
              or treatment of other constituents may reduce constituent concentrations to below
              the universal standards for some constituents. In these cases, our approach will
              underestimate the benefits of the rule.

       •      The TC capacity database did not provide comprehensive data for each of the
              regulated facilities.  Because EPA's approach focused on the highest-risk
              constituent for each facility, additional information on relatively low-level
              constituents would not be significant However, the exclusion of high-
              concentration or more  toxic constituents would tend to underestimate baseline
              risks and thus underestimate benefits.

       Factors with an indeterminate  effect on benefits:

       •      Leachate concentrations in the environment are assumed to be equal to TCLP
              concentrations reported in the TC survey.  It is not clear how closely the
              simulates actual long-term leaching behavior.

       •      The EPACML model used to calculate the DAF distribution assumes steady-state
              ground-water flow in a homogeneous, isotropic medium.  Because exposures to
              contaminated ground water may be time sensitive, and because actual
              hydrogeologic conditions  are often complex, this approach is limited in its ability to
              account for these factors. The steady-state assumption tends to overstate actual
              exposure concentrations;  the direction of bias associated with assuming
              homogeneous, isotropic media is not known.

       •      The DAF distribution used in this analysis was calculated by examining the
              environmental and exposure parameters associated with Subtitle D landfills.  While
              the DAF was adjusted  to account for the increased effectiveness of a Subtitle C
              landfill to limit leachate flow, the distribution was still fundamentally based on
              Subtitle D data.  Differences in location and surrounding land use between

Benefits                                                                             Page 5-51


              Subtitle D and Subtitle C landfills may result in differences to the DAF
              distribution. The direction and magnitude of the effects of these differences is
              uncertain.

       5.4.2   Air Risk Analysis

       Factors that overstate benefits:

       •      This analysis assumed that all constituent mass was available for volatilization.  In
              reality, only a portion of the mass would volatilize because some would leach into
              ground water or be transported by surface runoff.

       •      EPA did not estimate the air emissions and risks attributable to the treatment of
              waste in the post-regulatory alternatives.           '

       •      EPA assumed that indoor air concentration are equal to outdoor concentrations.
              In some situations, indoor air concentrations are not equal to outdoor air
              concentrations.  This can occur when (1) there is an indoor source of pollutant in
              which case concentrations are higher indoors, .(2) the pollutant is extremely
              reactive (e.g., ozone) and degrades rapidly indoors, and (3) the pollutant is from
              an outdoor source, and is associated with particulates. In the latter case,
              concentrations are often lower indoors than outdoors. Most of the emissions of
              concern for the Phase H LDR RIA are volatile emissions. None of the
              constituents is extremely reactive, and the source is not indoors.  Thus, it is
              reasonable to assume that indoor air concentrations are equal to outdoor air
              concentrations.  Nevertheless, this assumption  may slightly overstate baseline risks
              and benefits.

       •      EPA assumed continuous exposures over a seventy-year period.  Over the course
                                                     ^
              of the period, many people would spend much of their time away from home,  and

-------
Page 5-52
              many others would move to a different location. Thus, this assumption would
              overstate baseline risk (and risk reduction benefits) for these people.

       •      One of the facilities modeled to estimate air benefits includes a large wastestream
              generated from the clean-out of a surface impoundment. Because this stream is
              not expected to be generated in 1995, benefits associated with emissions from the
              stream will tend to overestimate the benefits of the rule.

       Factors that understate benefits:

       •      The analysis assumes one wastestream per facility.  To compute constituent
              concentrations for this one wastestream, EPA averaged the concentrations of each
              constituent across all TC wastestreams at the facility.  This generally decreased the
                  A
              concentration of a given constituent, often below TC regulatory levels, because
              concentrations were averaged across even those wastestreams that do  not cont
              the constituent.

       Factors with an indeterminate effect on benefits:

       •      The population risks were linearly extrapolated from the 35 facilities modelled to
              the 47 facilities known to exist in the universe.  Risks at the 12 facilities not
              modelled might be over- or understated, depending on how well the sample
              represents their waste volumes, constituent concentrations, and other factors.
              Approximately one-half of the TC wastes are sludges or debris, and these materials
              will volatilize organics differently than soil. However, EPA simulated air emissions
              by modeling all waste material as soil. For some sludges this is a reasonable
              assumption, while for other sludges and debris the assumption is less valid.

-------
Benefits      	•	Page 5-53


       •      The volatilization model assumes an infinite depth of contamination. Although the
              mass balance check in the analysis prevents more mass from volatilizing than is
                                                      • *
              present in the unit, the limitations inherent to the volatilization model apply to the
              analysis.

       •      Unit area was assumed to equal the annual volume of waste managed divided by a
              depth of four meters. Unit areas are therefore likely to have been over- and
              underestimated. The area is a key variable in the analysis, especially for the dust
              entrainment computation.

       •      EPA simulated air risks by assuming facility-specific population distributions and  by
              assuming on-site. landfill disposal.  However, the Agency determined that
              approximately 47 percent of the TC nonwastewaters were being managed in
              surface impoundments according to the 1992 TC survey. Because most of these
              impoundments are expected to close, these wastes are likely to be send to off-site
              locations for landfill disposal.   The Agency, therefore, examined the benefit results
              for the air pathway for 95 percent of the volume that was assigned to surface
              impoundment management by the 1C Survey. This volume was responsible for
              approximately 4 percent of the incremental benefits for the air pathway.
              Therefore, given available data, EPA believes that the uncertainty with regard to
              disposal location has no practical effect on the air benefits pathway results.

       •      The Agency  11 modeled land treatment units as landfills to calculate air emissions.
              This may either under- or over-state the risks from these facilities.

       5.4.3   Property Value Analysis
       As discussed in section 5.3, this is a preliminary analysis and EPA presents it to illustrate
the scale of potential property value benefits from TC waste treatment, rather than to measure
these benefits precisely.  The analysis has the following specific limitations:

       Factors that overstate benefits:

       •      A major assumption in the analysis is that it assumes that the effect of the LDRs
              for TC wastes can be represented as a conversion of Subtitle C to Subtitle D sites.

       •      Estimates of the numbers of houses near.facilities were based on estimates of
              house density in metropolitan areas.  For sites in small towns or rural areas, these
              estimates may overstate the actual numbers of houses affected.

       Factors that understate benefits:

       •      The distance beyond which waste sites have no significant effect on housing prices
              is uncertain. This analysis assumes no effect occurs beyond one mile from sites;
              other assumptions could significantly increase estimates of benefits.

       Factors with an indeterminate effect on benefits:

       •      The analysis is based on one study using data from one city, Baltimore, Maryland.

       •      The hedonic method itself produces uncertain results.  Though it is widely used
              and accepted, practitioners recognize that its results may vary significantly

               depending on the data and analytical methods used, residents' perceptions of
               environmental effects, and other factors.11

        •      Housing density and value data were not available for each town or city where
               facilities were located.  Instead, EPA used data for major cities reported in  the
               American Housing Survey since 1987, and averaged these data for this analysis.

       QUESTIONNAIRE FOR FACILITIES THAT LAND DISPOSE NEWI Y-iOENTIFIED
             ORGANIC WASTES EXHIBITING THE TOXICITY CHAHACTERISTIC
                                      INTRODUCTION
 Purpose of the Survey
   The U.S. Environmental Protection Agency's
Office of Solid Waste (OSW) is currently
developing regulations that will restrict the land
disposal of certain wastes exhibiting the
Toxicity Characteristic (TC)  (i.e., newly-
identified organic TC wastes: RCRA codes
0018 through 0043).  In preparation for the
land disposal restrictions (LDRs) of these
wastes, OSW is conducting a capacity analysis
to identify 1) the volume of newly-identified
organic TC wastes that will  require treatment
as a result of the LORs, and 2) the availability
of treatment/recovery systems to manage
newly-identified organic TC  wastes to meet
treatment standards. The results of this
analysis will be used to support EPA's
determination on whether to grant a national
capacity variance from the statutory date of the
LORs for newly-identified organic TC wastes.1

  To estimate the quantity of newly-identified
organic TC wastes that are  currently land
disposed and, therefore, may require treatment
upon promulgation of the LDRs, OSW is
conducting a focused data collection effort
This effort consists of a questionnaire for
facilities with land disposal units that are
permitted or have interim status to land
dispose the newly-identified organic TC
wastes.  [NOTE: LAND DISPOSAL UNITS REFER
TO UNITS USED TO TREAT, STORE, OR DISPOSE
HAZARDOUS WASTES IN OR ON THE LAND.
LAND DISPOSAL UNITS INCLUDE LANDFILLS,
SURFACE IMPOUNDMENTS,  LAND TREATMENT
UNITS, WASTE PILES, AND UNDERGROUND
INJECTION WELLS.]  Under Section 3007 of the
Resource Conservation and Recovery Act
(RCRA), 42 USC 6927, you are required to
provide EPA with the information requested in
this questionnaire.
  The purpose of this data collection effort is
to determine 1) the volumes of newly-identified
organic TC wastes that will require treatment
as a result of the LDRs. and 2) the availability
of on-site treatment and recovery systems to
manage newly-identified organic TC wastes.
(EPA is undertaking a separate effort to
evaluate the commercial availability of
treatment and recovery systems to manage
newly-identifjf 3 ar^snic TC wastes.)

How We P|«n to Collect thi* Information

  We have prepared  this questionnaire as a
guide for data collection. The questions in
each section of the questionnaire suggest a
format to present the  answers.  We expect
respondents to provide the data in the most
convenient means available.  Examples of
alternative ways to answer the questionnaire
include sending computer printouts or copies
of internal  records and downloading electronic
data                                 -

  We are providing contractor support to
assist facilities  in responding to the
questionnaire and we plan to work closely with
you. Prakash Ramaswamy of ICF Incorporated
has already contacted your facility and will
serve as your primary contact.  After you have
read through the questionnaire, but before you
begin to assemble the information, we
encourage you to contact Prakash
Ramaswamy at (703)  934-3426. Also, please
feel free to call Bengie Carroll or Pan Lee, U.S.
EPA, Capacity  Programs Branch at (703) 308-
8440.

Who Should Respond
                         • ' "
  Only facilities that have managed the newly-
identified organic TC  wastes in  land disposal
    1The LDRs are effective when promulgated unless the Administrator grants a national capacity variance from
me otherwise applicable date and establishes a different date (not to exceed two yeairs bayond the statutory
deadline) based on...the earliest date on which adequate alternative treatment, recovery, or disposal capacity which
protects human health and the environment will be available (RCRA Section 3004(h)(2)).  Case-by-case extensions
of the variance may also be granted to facilities demonstrating that there is a  binding contractual commitment to
construct or otherwise provide alternative capacity but due to circumstances beyond the applicant's control,
alternative capacity cannot reasonably be made available by the effective date (RCRA Section 3004(n)(3)).

questionnaire.  Newty-tdentjfied organic TC
wastes are defined as those wastes that have
an EPA hazardous waste code of DOIB
through 0043 in 40 CFR 261.24. Each waste
code corresponds to an  organic constituent
determined by the-Toxicity Characteristic
Leaching Procedure (TCLP) to exceed the
promulgated regulatory level. The codes and
corresponding constituents are listed in
Appendix A.

  Facilities that do not land dispose newly-
identified organic TC wastes (Le., do not
dispose, store, or  treat newly-identified organic
TC wastes in landfills, surface impoundments,
land treatment units, waste piles, or
underground injection wells) only need to
complete Section  I of this questionnaire.

QUESTIONNAIRE FOR FACILTTTES THAT LAND DISPOSE NEWLY-IDENTIFIED ORGANIC TC WASTES
Section II.     UNO DISPOSAL UNITS

   This section requests information on the land disposal units at your facility.  For the capacity
analysis, we compare the total volume of wastes that are placed in or on the land prior to the effective
date of the standard with the total national capacity capable of meeting the LOR treatment standards.
The data you provide will be used to determine the volumes of wastes that are placed in or on the
land.  We will use your responses on specific units to determine whether the volumes managed in the
units will be included in the demand for needed treatment as a result of the  LDFts.  For example,

units. We will use this information and the proposed LDR treatment standards for TC wastes to assign
each waste stream to an appropriate treatment train such that the waste will meet the proposed
treatment standards.  Although we use facility specific information to estimate the national demand for
treatment as a result of the LDRs, this assignment is for analytical purposes only. We are not making
any a priori judgements on how your facility wHI actually respond to the LDRs.

QUESTIONNAIRE FOR FACILITIES THAT LAND DISPOSE NEWLY-IDENTIFIED ORGANIC TC WASTES
Section IV.    TREATMENT OR RECOVERY SYSTEMS FOR MANAGING NEWLY-IDENTIFIED
              ORGANIC TC WASTES
   Did the facility treat or recover newly-identified organic TC wastes, including TC-contaminated
   soil and debris, in 1991 or does the facility have plans to treat or recover newly identified TC
   wastes, including TC-contaminated soil and debris, during 1992 to 1995?    *

   LJ Yes: Copy and complete Section IV for each treatment or recovery system used for or
             planned to be used for managing the newfy-identified organic TC wastes.  For
             planned uses of a particular system, onfy indicate those treatment or recovery
             systems, that in your judgement, are,appropriate for managing organics and are
             capable of treating the wastes to the characteristic levels.  Assign a unique number
             to each system and indicate the number on each page.

   LJ No:  Proceed to Section V.
   This section requests information on on-site treatment or recovery systems mat are being used or
could be used to manage organic TC wastes.  Following promulgation of the LDRs for TC wastes,
some on-site systems will be used to treat wastes that are currently being managed in land disposal.
units. We will use the information in this section to determine the availability of on-site treatment
systems for managing TC wastes requiring treatment following promulgation of the LDRs. Therefore,
based on this information, we will adjust the total national volumes of TC waste that wfll require off-site
commercial treatment  Although we use facility-specific information for the capacity analysis, we are
not making any judgements on how your facility will actually manage wastes following promulgation of
the LDRs (i.e., our use of the information is for analytical purposes only).

   For each treatment or recovery system, Questions 42 through 53 request information on the
operational status of the system, the types and quantities of wastes being managed, and the
limitations and potential obstacles in the use of the system for TC wastes.  Questions 54 through 56
address whether the system can treat newly-identified organic TC wastes to or below the
characteristic levels.

               EXAMPLE CALCULATIONS FOR ESTIMATING EMISSIONS
                     (HUMAN HEALTH BENEFITS - AIR PATHWAY)
       Listed below is the step-by-step approach, with example calculations, that was used for
calculating emissions in estimating benefits from the air pathway.  For the sake of example, these
calculations are based on a hypothetical source scenario and use equations and parameter values
in the Phase n LDR benefits analysis, for all equations, the parameters are defined at the end of
this appendix.
Hypothetical Source Scenario

       A waste containing benzene at a concentration of 1,000 ppm «•- .c miration is being
managed at a Subtitle C landfill. The total waste volume managed in *iie landfill is 16,200 cubic
meters. Assuming a depth of 4 meters, the surface area of the landfill i  about 4,050 square
meters.

Calculations Used to Estimate Total Emission Rates

       The "total emission rate" is the sum of the volatilization emission and participate emission
rates. The only paniculate emissions considered in the analysis are those due to wind and
vehicular traffic. The emissions resulting from other mechanical disturbance!, such as loading and
unloading operations and daily spreading operations are ignored because they result in very low
emissions compared to volatilization emissions for TC constituents.

        A* Volatilization Emissions



        The volatilization algorithm described by Hwang and Falco1 is used to calculate N, the

 mass flux (g/s/cm2) from uncovered landfills.

       B.  Estimate Particulate Emissions


       The empirical equations described in Cowherd2 are used for estimating emissions due to

wind, and an EPA source3 is used for estimating emissions from vehicu  «r traffic.  Calculations

showing paniculate emissions from wind erosion and vehicular traffic are shown below.


       B.1    Particulate Emissions due to Wind Erosion


       The equation used to represent the wind erosion of inhalable particulates, PM10wind, is
                                                lpr[V(i)X..XF2

       B.2    Particulate Emissions due to Vehicle Traffic

       The empirical equation used to represent the emission factor for particulates,
(kg/VKT), from an unpaved landfill per vehicle kilometers traveled per hour, VKT, is
                                                                                       <»>
The average hourly emission due to vehicle traffic, PM10veb, is then estimated as
                                   - 1,000 fc/fc) x Emv x VKT                      (9)

       The total emission rate, N^, is calculated as the sum of the emission rates from
volatilization emissions and paniculate emissions from wind erosion and mechanical disturbances.
Note that the emission rate from volatilization is the product of mass flux (N) and unit area

       Ntot   = [N x AJ + [( PM10wind + PM10veh )  x q x (1/3600)]

a.     The Phase II  rule Mill set treatment standards for TC wastes at "universal standard" levels.  For
       organics, universal standards will be based on totals analysis (i.e.,  ng/kfl), and for BetaIs
       universal standards will be based on leechate analysis (i.e., «g/l).  Post-regulatory concentrations
       for organics  in this appendix have been calculated by applying the Organic Leachate Model (OLN) to
       the totals concentrations in drafts of the Phase II LDRs rule.

b.     The risk specific doses (RSDs) in this appendix are based on 10   excess lifeline cancer risk.

                          Overview of the GEMS/GAMS Model
i
       The Graphical Exposure Modeling System (GEMS) is a computerized information
management tool designed to allow quick analysis of environmental problems. GEMS has
evolved, since its development in 1981, into a system that combines the power of over 40 different
modeling and statistical analytical tools into one easy-to-use system. GEMS ties together several
previously discrete analysis tools into a coordinated system that allows for multiple types of
analysis.  It facilitates the extraction and manipulation of data from several component databases
and models.  GEMS is used primarily to assess the fate of chemicals released to the environment
and to determine the extent of hunian exposure and  resultant risk.  GEMS allows the user to:

       •     Estimate chemical properties:                                     •
       •     Assess the fate of chemicals in receiving environments:
       •     Model resulting chemical concentrations;
       •     Determine the number of people potentially exposed; and
       •     Estimate the resultant human exposure and risk.

       GEMS is housed on the VAX Ouster of computers at the National Computer Center
(NCC).  Once an account with the NCC has been opened. GEMS can be accessed using a
personal computer and a modem by dialing into the mainframe. The system uses several
environmental models to simulate the migration of chemicals through air. soil, groundwater. and
surface water. The fate of a chemical can be evaluated using a model for one media or
multimedia. The key steps involved in using GEMS are: (1) choosing a model; (2) data inp
running the model: and. (4) viewing output tables.

       GEMS provides four different models to estimate concentrations of chemicals released
into the air.  These four models are: GEMS Atmospheric Modeling Subsystem (GAMS).
INtegrated PUFF (INPUFF), PoinT PLUme (PTPLU), and BOXMOD.  In general. BOXMOD
and PTPLU are used as screening-level models and GAMS and INPUFF are  used for more
refined analysis. For the current modeling task. GAMS was selected as the atmospheric model
since it is the only non-screening model that estimates annual average concentrations, annual
exposure, and lifetime and annual cancer risk.  In addition, GAMS incorporates the Industrial
Source Complex Long-Tenn (ISCLT) model. Furthermore, GAMS can consider up to twenty
source categories with up to nine emission type entries within each category for an unlimited
number of source locations for modeling.

       ISCLT is EPA's state-of-the-art atmospheric  model that combines and enhances various
dispersion model algorithms into a computer program that can be used to assess the air quality
impact of emissions from a wide variety of sources associated with an industrial source complex
ISCLT may be used as either a screening or a detailed model to estimate atmospheric
concentration or deposition values. It is possible to estimate the population exposed to various

Substances, U.S. EPA, March 1989 and 'GAMS Version 3.0 User's Guide,' Office of Pesticides and Toxic

levels of pollutant concentration through the integration of ISCLT within GAMS.  ISCLT is
implemented in GAMS to estimate annual average concentrations around each source on a polar
coordinate system.  Concentration estimates are calculated at three points along the centerline of
each sector segment.  ISCLT accepts stack, area, and volume source types: for the Phase II LDR
RIA. EPA simulated area sources.

       The GAMS Exposure and Risk Estimation (GAMSERE) procedure is used to generate
exposure and risk estimations* based on the results of ISCLT modeling. Two basic types of
GAMS reports. Comptabs and Digests, can be generated from GAMSERE.  The Comptabs are
comprehensive tables of results that can be tabulated by a combination of source category and
emission type, by source category, by emission type, and across all source categories and emission
types. The exposure and dosage tables give cumulative population exposed by concentration
level, and the risk tables give population exposed; order of magnitude risk levels, and excess cases
of cancer.

       The Digests contain total results compiled by source category. An Exposure Digest
contains the maximum, minimum, and weighted average estimated concentrations: the total
modeled population: and the total exposure by source category.  The Risk Digest contains
population at risk by order of magnitude risk levels and by source category. The Cases Digest
contains the modeled population, the weighted average individual risk, the total number of
estimated lifetime excess cancer cases, annual incidence, the maximum exposed individual risk, and
the number of persons exposed at the maximum risk  by source category. For further information
on GEMS/GAMS, refer to "GEMS User's Guide." Office of Toxic Substances. U.S. EPA, March
1989 and "GAMS Version 3.0 User's Guide," Office of Pesticides and Toxic Substances, U.S.

                       Waste Minimization Commercial TSD Analysis

       The data in the spreadsheet were sorted by industry and 1995 quantity.  The commercial
TSDs associated with the 15 lines with the largest 1995 quantity were then analyzed in the TCDMS
according to their potential for waste minimization.

       One TSD reported receiving a sporadically generated 17,865 ton wastestream from
       a  chemical  company with no waste description.  Based on  available physical
       information (75 percent solids, 5 percent water, and 20 percent oil and grease values
       reported in TCDMS) the waste minimization potential for this wastestream cannot
       be determined.

       Another TSD reported receiving a routinely generated 13,351 ton primary wastewater
       treatment sludge from an unknown facility containing vinyl chloride left over from the
       conversion to polyvinyl chloride. The only physical chemical data reported in TCDMS
       was  a TOC (total organic carbon) value of 15  percent and an EOX  (extractable
       organic halide) value of 640 ppm. The generating facility may have significant waste
       minimization potential. However, the available information is insufficient to quantify
       any savings.

       A third TSD  reported receiving three routinely generated wastestreams totaling
       25,350 tons from a hazardous waste incinerator described as incinerator ash. Waste
       codes  D018, D022, D019, D021,  D020,  and  D023 are  associated  with these
       wastestreams.  The waste minimization potential at a well operated hazardous waste
    .   incinerator is minimal. Last minute changes to the cost analysis data eliminated this
       wastestream from the Phase n rule cost analysis because listed waste codes were
       combined with TC codes in these streams.

       This third TSD also reported receiving a routinely generated 3,670 ton wastestream
       from a petroleum refinery described as an oil/water separator sludge with benzene and
       polymers.  No physical chemical property data was reported.  However, a note was
       made that the polymers affect the treatability of this wastestream. This wastestream
       has significant potential for waste minimization; however, the available  information
       is insufficient to establish a case study to quantify the savings.

       A fourth TSD reported receiving a routinely generated 10,222 ton wastestream from
       a hazardous waste treatment facility described as "CHEM  PAC, treatment of
       hazardous and nonhazardous wastes."  Because this waste appears to be a residual
       from waste treatment operations, waste minimization potential is minimal.

       These seven wastestreams account for 72 percent of the routinely generated, and 80 percent
of the sporadically generated, nonwastewater waste reported as received by TSDs.

       An evaluation of the debris received by TSDs was attempted. Two TSDs account for 19,410
tons or 81.6 percent of the debris reported One hazardous waste landfill reports wastestream
number 1 as 9,245 tons.  However,  in  the TCDMS no  waste  descriptions are provide for any

-------
wastestreams and no wastestream number 1 is reported.  Another hazardous waste landfill accounts
for the remaining 10,165 tons. However, no wastestreams are present in TCDMS for survey number
2.

                Summary of Waste Minimization Analysis Telephone Contacts


       Presented below are the results of telephone contacts made as a follow-up to the Toxicity
Characteristic (TC) waste survey conducted in 1992. Sixteen facilities were contacted for
information on waste management activities for newly listed TC waste subject to EPA's Phase n
rule-making. Exhibit J-l presents the protocol for the, telephone contacts.

Chemical Company A • This facility indicated that it manages the following nonwastewater waste
streams affected by the TC rule: lube oil sludge; several liquid, solid, and byproduct streams, and
dirt contaminated with TC organics, i.e., D018.  Waste minimization activities were being
conducted on several of the liquid and sludge byproduct streams. The waste minimization
activities consist of recycling two liquid TC wastes in one plant that would otherwise be
incinerated. The facility also removed one piece of equipment that generated a TC sludge that
was previously incinerated.  The facility reported that approximately 1,050 tons of waste were
reduced as a result of waste minimization efforts. The facility stated that it saved approximately
$215,000 ($205/tbn) in 1993 by employing waste minimization on its waste streams.

Chemical Company A indicated that economic considerations were the overriding impetus for
waste minimization activities. The TC rule did play a minor role  in driving the waste minimization
activities.

Petroleum Refinery A -  This facility indicated that its crude tank bottoms (D018) are affected by
the TC rule. The major thrust of the waste minimization activities consists of source control.
Other efforts involve putting the crude tank bottoms through a centrifuge and extracting the
benzene and recycling it back to the refinery.  A lime sludge (D018) is generated that is
dewatered and sent to a cement kiln as raw material substitute. The facility pays the kiln to
accept the waste and the waste's the transportation costs. The facility estimates that  12,000 tons
of lime sludge are reduced at the plant (the major portion due to source control).  Shell estimates
that the economic  benefit due to waste minimization is $250,000 per year.
                                                 \

Petroleum Refinery A indicated that the waste minimization efforts are strictly driven by
economics which is in turn driven by the TC rule that requires treatment of hazardous wastes to
LDR standards.                              •

Petroleum Refinery B - This facility reported managing D018 streams that included catalysts (160
tons/1993), tank bottoms (206  tons/1993), and activated carbon (13 tons/1993). However, none of
these waste  streams were reported on the 1992 survey.  The facility reported that it found it
difficult to employ waste minimization on these wastes.  D018 catalysts and activated  carbon are
sent to offsite regeneration.  However, the facility anticipated that the Phase n LDR standards
would make the vendors less likely to accept these materials.

       The facility cited the Phase n LDR treatment standards as being the driving force  behind
its waste minimization plans.

Chemical Company B • This facility managed  a D028 waste stream. Waste minimization activities
have been instituted since 1988. These include process changes and segregation of nonhazardous
and hazardous waste streams.  The D028 generation in 1993 was 2,600 tons versus 5,550 tons in

-------
 1988 for an annual cost savings of $304,000 (or about $100 per ton).  Current plans include an
 additional reduction of 80 percent by 1999 for an estimated future cost savings of $1,125,000 (or
 about $500 per ton).

       Hie facility stated that its primary reason for employing waste minimization activities were
 economic, such as for product recovery, rather than the Phase n rule itself.

 Petroleum Refinery C - This facility indicated that several of its waste streams are affected by the
 TC rule. These waste streams are: butamen catalyst (D018); benzene organic sludge from tank
 cleaning operations; butamen drier catalyst from alkylation of crude oil in gasoline refining;
 benzene organic sludge from tank cleaning operations (600 tons); and, DAF and API sludge
 (2,400 tons). Of-these waste streams, the benzene sludge was land farmed (this activity is
 suspended until a permit is granted), and the DAF and API sludge is used as raw materials in the
 coker feed. The estimated economic benefit from the land fanning of the D018 benzene sludge
 was $570/ton.  An additional savings of $600/ton for the DAF and API sludge is realized using
 these materials as feedstock for the coker rather than disposing of these materials as wastes.

 Chemical Company C • This facility indicated that its wastes affected by the TC rule were
 catalysts.  By employing offsite regeneration,  it eliminated this waste stream in 1993, a reduction
 of 270 tons. However, this waste stream is not part of the 1992 survey information.

       The facility cited the Phase n LDR treatment standards as being the driving force behind
 its waste minimization plans.

 Petroleum Refinery D - This facility indicated its D018 wastestream as tank bottoms. Waste
 minimization activities attempted on these wastes have not been successful.

              Sensitivity Analysis of Ground-Water Population Risk Assumptions
       This appendix details the sensitivity analysis performed on the radius used for the ground-
water benefits analysis.  The DAF used in the analysis was first developed for the TC Rule RIA
and considered only those drinking water wells within one mile of a facility. For the Phase n
LDR RIA, the DAF distribution was applied to wells within two miles of a  facility. The DAF was
not mathematically corrected to extend from the one mile distance used in the TC analysis to the
two miles used for this rule.  Therefore, EPA performed a sensitivity analysis reanalyzing the
gfoundwater risk, considering only wells within a one-mile radius. This appendix is organized into
two sections: the first explains the approach and die second presents the results of the analysis.
                                   ,.                                     *
Approach

       As is explained in Step 6 of Section 5.1.1 of the RIA, EPA estimated exposed populations
by (1) determining the number of people exposed to contaminated ground-waiter via wells located
within two miles of facilities from the corrective action RIA sample, (2) using these numbers,
along with population density values for the corrective  action sample facilities, to calculate ratios
of total to exposed populations, and  (3) applying these ratios to the Phase n sample facilities.

       EPA tested the sensitivity of the radius used to calculate exposed populations by
determining the number of people exposed to contaminated ground water via wells located within
one mile of facilities from the corrective action RIA sample.  As a result of this change, the total-
to-exposed-population ratios also changed. The base analysis assumed that, for low-density
settings, 0.4 times the total population  in the  90 degree, two-mile sector would be exposed, and
that 0.05 times the total population would be exposed in high-density settings.

       Using estimates based on  a one-mile radius, EPA calculated that, for low-density settings,
1.4 times the total population in the  90 degree, one-mile sector would be exposed, and that 0.1
times the total population would be exposed in high-density settings. The seemingly counter-
intuitive ratio for the low-density scenario (i.e., the exposed population is greater than the total
population)  is caused by the effects of  a large public supply well that is located within one mile of
one of the corrective action sample facilities.  Under the two-mile approach, 10 of the 37 low-
density facilities had ground-water exposures, totalling 57,210 exposed people out of a total
population in the two-mile sectors of 91,240 people.  Furthermore, of the 57,210 exposures,
52,500 were associated with a public well at one facility.  Under the one-mile scenario, nine of the
facilities have exposures, totalling 56,780 people. As with the two-mile scenario, this total is
dominated by exposures from the same single facility.  The total population under the one-mile
scenario, however, is only 22,810  (i.e., one-fourth of the two-mile scenario because the same
densities are assumed). Because the decrease of total exposed population is much less that the
decrease in the total potential population, the ratio is increased such that it exceeds unity. Note
that the final ratios used in the analysis represent the average of the facility-specific ratios, rather
that the ratio of the total exposed population to the total potential population. However, looking
at the totals helps to explain the general trend.

-------
       Using these revised ratios, the Agency estimated total exposed populations for each of the
Phase II sample facilities. Note that while the ratios increase, the total affected populations
decrease because, assuming a uniform population density, the total population within one mile is
only one-fourth of the total population within two miles.

Results

       Under the base approach (as was shown in RIA Exhibit 5-8), the rule reduces 0.22 cancer
cases per year with  respect to the central tendency baseline or, in other words, 92 percent of the
baseline cancer cases.  For non-cancer effects (as was shown in RIA Exhibit 5-9) two of the 36
facilities  had exposures above threshold doses, totalling 2,038 exposed people.

       The results of the sensitivity analysis indicate that, under the one-mile approach, the rule
reduces 0.18 cancer cases per year with respect to the central tendency baseline or, in other
words, 91 percent of the baseline cancer cases. For non-cancer effects the same two facilities, had
exposures above threshold doses, now totalling 1,136 exposed people.
