            INTRODUCTION
The Resource Conservation and Recovery Act (RCRA)/Superfund (SF)/Office of
Underground Storage Tanks (OUST) and Emergency Planning and Community Right-to-
Know (EPCRA) Hotlines were established to respond to inquiries from the regulated
community and the public concerning waste management and disposal regulations. The
Hotline also serves as a referral point on the availability and distribution of program
related documents and published materials.

This document is a compilation of Questions and Answers and Federal Register summaries
from individual Monthly Hotline Reports for the period of January to December 1992.  It is
divided into three parts:  Questions and Answers, Federal Register summaries, and Indices
to the questions, according to subject matter, regulatory and statutory citations.

It is important that the reader be aware of the purpose and limitations of the information
in this document.  Neither the questions nor the Federal Register summaries are intended to
fully represent or be used in place of the regulations. This document can be used by its reader
to explore the application of the regulations in different scenarios or to shed light on
complex issues. For an understanding of the actual regulatory requirements in any given
situation, the reader must consult the appropriate sections of Title 40 of the Code of Federal
Regulations (CFR), pertinent Federal Registers and EPA guidance documents, as  well as
relevant State regulations.

            PART  1:   QUESTIONS  AND  ANSWERS
This section contains a compilation of all the questions and answers from individual
RCRA/Superfund/OUST and EPCRA Hotline Monthly Reports for the period of
January to December 1992. The questions in these reports arise from actual Hotline
calls. While the number of questions represent only a small fraction of the total
questions received, they do represent commonly asked or significant questions received
by the Hotline. During 1992 the Hotline responded to over 200,000 questions regarding
EPA regulations, programs, guidance documents, and other related matters. Of the
207,781 questions received, over two thirds of the questions concerned regulatory
information and nearly one quarter wanted EPA documents. Nine percent of the queries
were not within the  Hotline's purview to answer and were referred to an appropriate
information source.  Figure 2 breaks down the questions by program area. The RCRA
program received the highest number of questions, nearly 60 percent. The number and
type of questions in  this report reflect the percentages cited in Figure 2.

The answers to the questions have undergone program and legal review and often reference
other pertinent sources of information such as CFR citations, Federal Register notices, and
Agency memoranda. These explanations and examples of regulatory application are for
informational purposes only, and do not represent the issuance of formal policy or in any
way affect  the implementation of the regulations.

Keywords are provided in the left-hand margin at the beginning of each question.  The
month the question  appeared in the "Hotline Monthly Report" is cited at the end of the
entry. To pinpoint a subject or topic more specific than the general regulatory area
headings, please use the Indices in Part 3. The questions in this section are grouped by EPA
program area, then further grouped  under broad, general regulatory areas and titles.

Key Words:

Funding: reauthorization
"Funding for the RCRA  Program  and  RCRA Reauthorization"

QUESTION: What is the current status of the funding for the Resource
Conservation and Recovery Act (RCRA) program? When will the RCRA
statute be reauthorized?

ANSWER: When the Hazardous and Solid Waste Amendments of 1984
(HSWA) amended RCRA, §2007(a) authorized funding for the RCRA
program through September 30,1988. There have been no changes made to
§2007(a) since 1984. Instead, funding for the RCRA program has been
provided through an annual Congressional  "de-facto" appropriations
process. Through this process, Congress is able to appropriate money to EPA
without going through the lengthy process of reauthorizing the statute. If
Congress does not appropriate money, the funding for the program would
expire. EPA's authority to regulate pursuant to RCRA, however, is
separate from all funding issues and would not be affected. Several
different bills addressing various solid  and hazardous waste issues have
been introduced in the House  and the Senate.  (January 1992 Monthly
Hotline Report)

Clarification: These bills were introduced during the 102nd Congress.
Comprehensive RCRA reauthorization bills had not been introduced during
the 103rd Congress as of the publication of the Annual Report.

"Resource Conservation and Recovery Information System
(RCRIS)"

QUESTION:  What is RCRIS?

ANSWER: The Resource Conservation and Recovery Information System
(RCRIS) is a major national information system that helps EPA Regions
and States in the daily operations and implementation of the RCRA
Subtitle C program.  As of December 1991, it was fully implemented by all
Regions and States, effectively superseding the Hazardous Waste Data
Management System (HWDMS). RCRIS also tracks data previously
contained in the Corrective Action Reporting System (CARS). Both
HWDMS and CARS were archived in January 1992.

RCRIS is both a program management and inventory system of RCRA
hazardous waste handlers. RCRIS captures identification and location
data for all handlers of hazardous waste and a wide range of information
on hazardous waste treatment, storage, and disposal facilities regarding
permit and closure status, compliance with Federal and State regulations,
and cleanup (corrective action) activities.

                            ANSWER: Data are collected from notification forms and permit
                            applications submitted by hazardous waste handlers, as well as from
                            information gathered at inspections. EPA Regions and RCRA-authorized
                            States enter information directly into RCRIS. Core data from the Regions
                            and States are then uploaded to the RCRIS National Oversight database
                            monthly for use by EPA Headquarters in its oversight of the RCRA program
                            and to respond to public requests for information.  (March 1992 Monthly

"Accumulation Time for Hazardous Waste Importers"

QUESTION: A U.S. hazardous waste broker wishes to import hazardous
waste by truck from Mexico into the United States. Assuming the shipment
passes U.S. Customs, the broker wishes to accumulate the hazardous waste
at a warehouse near the border for 45 days in order to consolidate several
shipments before transporting the hazardous waste to a designated TSDF.
According to 40 CFR §262.60, an importer of hazardous waste must comply
with the generator requirements of 40 CFR Part 262.  Section 262.20 also
requires the importer to comply with certain manifesting requirements
specific to imports (§262.60(b)). Once the waste is imported into the United
States, can the importer accumulate hazardous waste (per §262.34) at or
near the point of entry to the United States (e.g., in a warehouse) for 90
days or less without a permit or interim status prior to shipping it to the
designated TSDF?

ANSWER:  Although it is correct that importers must comply with Part
262, Standards Applicable to Generators, including the special
requirements of Part 262, Subpart F, importers cannot accumulate hazardous
waste under §262.34. Ninety-day accumulation under §262.34 applies only
to generator accumulation on-site, and is not applicable to this situation.
Sections 262.20 and 262.60 require the importer to prepare a hazardous
waste manifest for the waste shipment, using the importer's name and the
name of the foreign generator in the generator box. At the time the
manifest is initiated (at the point of entry into the United States) the
waste shipment is already in transportation, and the manifested
hazardous waste must proceed to the facility designated on the manifest to
accept the hazardous waste. Under §263.12, the hazardous waste may be
stored during the normal course of transportation to the designated facility
at a transfer facility for 10 days or less, provided that the hazardous waste
is packaged in accordance with DOT packaging regulations.  (August 1992
Monthly Hotline Report)

Key Words:

Containment building;
generator accumulation;
interim status; LDR
notification; permit;
treatment
QUESTION: According to the March 24,1986, Federal Register, generators
may treat hazardous waste in accumulation tanks or containers in
conformance with the requirements of §262.34 and Subparts J or I of Part 265
without obtaining a permit or interim status (51 FR 10168).  In the August
18,1992, Federal Register (57 FR 37194), EPA promulgated standards for a
new hazardous waste management unit known as a containment building
(Parts 264 and 265, Subpart DD), and amended §262.34 to allow generators
to accumulate hazardous waste on-site in containment buildings for 90 days
or less without a permit or interim status (§262.34(a)(iv); 57 FR 37264).
May generators accumulating hazardous waste in containment buildings in
compliance with §262.34 and Part 265, Subpart DD treat the waste without
obtaining a permit or interim status?

ANSWER:  A generator accumulating hazardous waste in a containment
building for less than 90 days in compliance with §262.34 and Part 265,
Subpart DD (the technical standards for interim status containment
buildings) may treat these hazardous wastes in the containment building
without obtaining a permit or interim status as long as thermal treatment is
not involved. The August 18,1992, Federal Register states that §262.34 has
been revised to exempt generators from permitting requirements when
accumulating or treating hazardous waste on-site in containment buildings
(57 FR 37242 and 37253). Generators who accumulate or treat hazardous
waste in containment buildings must comply with the general Part 262
regulations, as well as the following requirements in accordance with
§262.34(a)(l)(iv): comply with Subpart DD of 40 CFR Part 265; place in
the facility's operating record a certification by a professional engineer
that the building complies with the design standards specified in 40 CFR
§265.1101; and maintain in the facility's files documentation showing no
hazardous wastes remain in the unit for longer than 90 days (57 FR 37264).

If a generator chooses to treat a prohibited hazardous waste in containment
buildings, however, and is conducting such treatment in order to meet
applicable Part 268, Subpart D treatment standards, he or she must comply
with the waste analysis plan requirements of §268.7(a)(4).  Section
268.7(a)(4) has been modified to reflect the addition of containment
buildings to §262.34 as accumulation/treatment units (57 FR 37270).

Thermal treatment is regulated by the specific standards for incinerators
(Part 265, Subpart O), boilers and industrial furnaces (Part 266, Subpart H),
and thermal treatment (Part 265, Subpart P), and is therefore not eligible
for the §262.34 permit exemption even if the treatment occurs inside a
containment building. (August 1992 Monthly Hotline Report)

"Fluorescent Light  Bulbs as Debris"

QUESTION: The May 15,1992, Federal Register (57 FR 20766)
promulgated a generic one-year, case-by-case extension of the land disposal
restrictions (LDR) effective date for most hazardous debris.  Debris
qualifying for this extension may be land disposed without meeting the
applicable Part 268, Subpart D treatment standards, provided  the landfill
or surface impoundment in which the hazardous debris is placed meets
minimum technological requirements (§268.5(h)(2)). Do used fluorescent
light bulbs that exhibit a prohibited characteristic (e.g., exhibit the
toxicity characteristic (TC) and the extraction procedure toxicity
characteristic (EP) for mercury) meet the definition of  debris and therefore
qualify for  the case-by-case  extension?

ANSWER:  Used fluorescent light bulbs are considered debris and are
eligible for  the generic one-year case-by-case extension. The May 15, 1992,
Federal Register (57 FR 20767)  established this extension for materials
that meet the definition of debris found in the Third Third final rule (55 FR
22650; June 1, 1990) and that are contaminated with hazardous  waste (with
the exception of debris contaminated with solvent, dioxin, and nonliquid
California List wastes).  This definition of debris includes materials that
are primarily nongeologic in origin, such as grass, trees, stumps,  shrubs, and
man-made  materials. In August 1992,  EPA established alternative
treatment standards for hazardous debris in 40 CFR §268.45 and
promulgated regulatory definitions of debris and hazardous debris in
§§268.2(g) and (h), respectively. The definition of debris in §268.2(g)
classifies as debris solid materials exceeding a 60 mm particle size that are
intended for disposal and that are manufactured  objects, plant or animal
matter, or natural geologic material (with several exceptions specified in
§268.2(g)) (57 FR 37222; August 18, 1992). This definition also includes
mixtures of debris with other materials provided that  the debris comprises
the primary material present based on a visual inspection (57 FR 37224).
Although the May 1992 Federal Register uses the definition of debris found
in the Third Third final  rule, EPA has stated that  the case-by-case
extension applies to materials meeting either definition of debris (57 FR
37242). Fluorescent light bulbs, which are man-made (manufactured)
materials exceeding a 60 mm particle size, meet both definitions when
intended for discard, and thus qualify for the one-year case-by-case
extension, provided the generator or facility owner/operator complies with
the recordkeeping requirements outlined in the May 15,1992, Federal
Reeistcr  (57 FR 20769).

"Fluorescent  Light Bulbs as  Debris"  (cont'd)

Even if the fluorescent light bulbs are broken into pieces that have a
particle size of less than or equal to 60 mm, the pieces are still eligible for
the one-year case-by-case extension.  Broken light bulbs meet the June 1,
1990, Federal Register definition of debris, which does not contain a
minimum particle size criterion for materials other than  indigenous rocks
(55 FR 22650); therefore, regardless of the diameter of the pieces, broken
light bulbs are considered debris for purposes of the generic one-year case-
by-case extension. (September 1992 Monthly Hotline Report)

Clarification: After  expiration of the case-by-case extension, these
materials may or may not be subject  to the debris standards.  At that time
the June 1,1990, Federal Register definition of debris will no longer be
applicable.

"One-Time  Notification  Requirement  Under  §268.7(a)(6)"

QUESTION: A manufacturer generates a listed, restricted waste which is
piped directly to a wastewater treatment unit exempt from RCRA
regulation under §§264.1 (g)(6), 265.1(c)(10), and 270.1(c)(2)(v).  After
treatment, the listed  waste is discharged directly to a POTW pursuant to
§261.4(a)(l)(ii).  Because the  waste is never managed in  accumulation tanks
or containers regulated under §262.34, it is not subject  to "substantive
regulation" as defined in the March 24, 1986, Federal Register (51 FR 10152-
3), and so is not counted in determining generator status (i.e., conditionally
exempt, small quantity, or large quantity generator). Which Part 268 land
disposal restrictions  notification requirements, if any, apply to this waste?

ANSWER: The generator must comply with the one-time notification
requirement under §268.7(a)(6). This section states, "[i]f a generator
determines that he is managing a restricted  waste that is excluded from the
definition of hazardous or solid waste or exempt from Subtitle C regulation,
under 40 CFR 261.2-261.6 subsequent  to the point of generation, he must
place a one-time notice stating such generation, subsequent exclusion from
the definition of solid or hazardous waste or exemption from Subtitle C
regulation, and the disposition of the  waste, in the facility's file"
(emphasis added).  In the scenario presented above, the  waste is generated
during the manufacturing process and becomes excluded from the definition
of solid waste at the point of discharge to the POTW (§261.4(a)(l)(ii)); in
other words, subsequent to the point of generation (see 56 FR 3866;
January 31,1991). Therefore, the one-time notification requirement of
§268.7(a)(6) would apply even if, prior to discharge, the  generator does not
manage the waste in  a manner that subjects it to substantive regulation (i.e.,
the generator does not accumulate the waste in tanks or containers regulated
under §262.34).  (July 1992 Monthly Hotline Report)

"Medical Waste Tracking  Act Demonstration  Program"

QUESTION: What is the status of the Medical Waste Tracking Act
demonstration program, laid out in 40 CFR Part 259?

ANSWER: In response to the Medical Waste Tracking Act of 1988 (which
amended RCRA by adding Subtitle J), EPA established a two-year
demonstration program to track medical waste.  The program began June 22,
1989, and ended June 22,1991. Five States participated in the program:
Connecticut, New Jersey, New York, Puerto Rico, and Rhode Island. The
program has expired and only some of the Federal recordkeeping
regulations are currently in effect.

Section 11008 of RCRA required EPA to submit to Congress two interim
reports and a final report on medical waste management and the
demonstration program. The first and second interim reports were
submitted in May 1990 and December 1990. The first interim report
summarized information that was then available from the  tracking
program and outlined an agenda for additional research on  each of the 12
specific areas concerning medical waste that were identified in the Act.
The second interim report provided a research update and forecast on each
of these subject areas. The third and final report will summarize all the
information gathered, evaluate the success of the demonstration program,
and outline options for managing medical waste. The final report is
currently under Agency review and completion is expected late in 1992.
After EPA submits the final report, Congress will review the results of the
two-year program and determine the most appropriate course of action for
medical waste management. (February 1992 Monthly Hotline Report)

"Municipal  Solid  Waste Characterization"

QUESTION: How much municipal solid waste (MSW) is generated in the
United States each year?  What is the breakdown of the material by
category (e.g., plastics, paper, glass) and how much of each material is
recovered through recycling or composting?

ANSWER:  According to the EPA publication Characterization of
Municipal Solid Waste in the United  States: 1992 Update, in 1990 we
generated 195.7 million tons of municipal solid waste, or 4.3 pounds per
person per day. The municipal solid waste stream is broken down by
category in  the chart below.  These 1990 statistics show that the largest
component of the municipal solid waste stream is paper and paperboard
(37.5 percent) and the second largest is yard trimmings (17.9 percent).

                           Update (PB92-207 166) also summarizes how municipal solid waste is
                           managed (e.g., landfill, combustion, recovery). In 1990, the total amount of
                           material recovered from the municipal solid waste stream was 33.4 million
                           tons, or 17.1 percent. Combustion facilities handled 31.9 million tons, or 16.3
                           percent of the municipal solid waste generated. The remaining 130.4
                           million tons, or 66.6 percent of the municipal solid waste generated, were
                           sent to landfills.  By the year 2000, EPA projects that the amount of
                           municipal solid waste generated will reach 222 million tons, or 4.5 pounds
                           per person per day.  EPA continues to emphasize the importance of source
                           reduction and recycling as the first and second priority components of the
                           waste management hierarchy, and projects that the recovery rate for
                           municipal solid waste will increase to between 20 and 30 percent in 1995 and
                           between 25 and 35 percent in 2000.

"Municipal  Solid Waste Landfill Criteria"

QUESTION: On October 9,1991, EPA issued a final rule establishing
minimum national standards for municipal solid waste landfills
(MSWLFs). Most provisions of the rule will be effective October 9,1993 (56
FR 51017). All MSWLF units that receive waste after October 9, 1991 (the
date the rule was published), but stop receiving waste prior to the effective
date must still meet certain final cover requirements at closure. If a landfill
consists of three cells, and two of the cells closed before October 9,1991, is
the entire landfill subject to the new final cover requirements or just the one
cell that received  waste after the date of publication?

ANSWER: The new final cover requirements only apply to the third cell
that continued to receive waste after the publication date of the final rule
for MSWLFs. The regulations state that the new final cover standards
apply to MSWLF units receiving waste after October 9, 1991 (40 CFR
§258.1). Each landfill cell constitutes a separate MSWLF unit. The two
cells (units) which stopped receiving waste before publication of  the final
rule are not subject to the new final cover requirements or any other Part 258
requirement. The cell that continued to receive waste between the
publication date in 1991 and the effective date in 1993 is subject only to the
final cover requirements of 40 CFR §258.60(a). In addition to the new final
cover standards, all Part 258 requirements will apply to the third MSWLF
unit if it continues to receive waste after October 9,1993. Note that states
may have more stringent requirements regarding final cover, closure
requirements, and solid waste facilities in general. (November 1992

"Groundwater  Monitoring  at  Newly Regulated  Facilities"

QUESTION: The regulations in 40 CFR Part 265, Subpart F require owners
and operators of interim status surface impoundments, landfills, and land
treatment units to implement groundwater monitoring programs. Section
265.92 requires  these facilities to establish initial background
concentrations for three groups of indicator parameters.  Background
concentrations are established based on the results of quarterly groundwater
sampling during the first year. For newly regulated interim status
facilities or units, when must the background concentrations be
established - during the first year of interim status, or the first year the
groundwater monitoring system is operating?

-------
RESOURCE  CONSERVATION  AND  RECOVERY  ACT  (RCRA)
                           ANSWER: Owners and operators of newly regulated interim status
                           facilities or units must begin establishing background concentrations for the
                           indicator parameters in §§265.92(b)(l)-(3) as soon as the groundwater
                           monitoring system is installed. These facilities then have one year from
                           the date the system is operable to establish these background levels.
                           When interim status is triggered, §270.73(d)(2) requires owners and
                           operators of land disposal facilities to certify compliance with all
                           applicable groundwater monitoring requirements within 12 months.  Land
                           disposal facilities that do not certify compliance with these requirements
                           within 12 months automatically lose interim status. The September 27,
                           1990, Federal Register (55 FR 39411) clarifies §270.73(d)(2) by stating that
                           facilities newly subject to the Part 265, Subpart F groundwater monitoring
                           requirements must complete site characterization and design and
                           installation of groundwater monitoring systems within 12 months of
                           receiving interim status (also see October 1985 Hotline Monthly Report
                           question on loss of interim status). In other words, a newly regulated
                           interim status facility must have  characterized the hydrogeology of the
                           site and installed a groundwater monitoring system capable of determining
                           the facility's impact on groundwater quality by the end of the first year of
                           interim status at the latest.

                           Once owners or operators have completed the installation of groundwater
                           monitoring systems, they must then immediately begin establishing
                           background concentrations for the three groups of indicator parameters
                           specified in §§265.92(b)(l)-(3). These background concentrations are
                           established during the first year of operation of the groundwater
                           monitoring system. For newly regulated facilities or units, background
                           concentration levels must be established by the end of the second year of
                           interim status at the latest (sooner if the facility's groundwater monitoring
                           system was installed and operating before the end of the first year of
                           interim status).  For example, a facility with a surface impoundment that
                           became subject to RCRA regulation for the first time because of the TCLP
                           final rule had until September 25, 1991 (one year after the effective date of
                           the regulations), to certify that a groundwater monitoring system was
                           installed.  The facility then has until September 25, 1992, to establish
                           background concentration levels pursuant to §265.92. If this facility
                           finished installing its groundwater monitoring system before September 25,
                           1991 (e.g., on July 15,1991), background concentrations for the indicator
                           parameters would have to be established within one year of the date the
                           groundwater monitoring system became operable (by July 15,1992).  (April

"Groundwater Monitoring  Resampling  Requirements"

QUESTION: Owners or operators required to establish a compliance
monitoring program under 40 CFR §264.99 must sample all groundwater
monitoring wells located at the point of compliance for any chemical
parameter or hazardous constituent specified in the permit pursuant to
§264.99(a) at least semiannually, and for all Appendix IX constituents at
least annually (§§264.99(f) and (g)). If the groundwater contains any
additional Appendix IX constituents that are not already identified in the
facility permit as monitoring constituents, the owner or operator must report
the results of the analysis to the Regional Administrator within seven
days or resample within one month after the initial sampling.  If the owner
or operator chooses to resample, must he or she resample for all Appendix
IX constituents?

ANSWER: The owner or operator is not required to resample for all
Appendix IX constituents. Since the purpose of resampling is to verify the
presence of the additional constituents discovered in the initial sampling,
resampling is only performed on those Appendix IX constituents the owner
or operator wishes to contest.  If the owner or operator chooses to resample
and confirms the presence of the new constituents within seven days of the
second sampling, he or she must report the concentrations of these
additional constituents to the Regional Administrator and, through a
permit modification, add them to the monitoring list required by
§264.99(a)(l). The owner or operator must then monitor for these
constituents at least semiannually pursuant to §264.99(0. If, after
resampling, the second analysis does not confirm the initial analysis, then
the "unconfirmed" constituents are not added to the monitoring list and
notification to the Regional Administrator is not necessary.  This, however,
does not exempt the facility owner or operator from the annual Appendix IX
analysis pursuant to §264.99(g). In the event that the owner or operator
chooses  not to resample, he or she must report the results of the initial
sampling to the Regional Administrator and modify  the monitoring list no
later than seven days after the initial sampling.  (June 1992 Monthly

Key Words:

Interim status; land disposal
unit; minimum technological
requirements; permit
QUESTION: The Hazardous and Solid Waste Amendments (HSWA) of
1984 created new requirements for both permitted and interim status
hazardous waste land disposal units.  Initially, to satisfy the requirements
outlined in §3004(o), EPA promulgated minimum technological
requirements (i.e., double-liners) on July 15,1985 (50 FR 28702).  EPA
subsequently proposed two rules on liners and leak detection. On March 28,
1986 (51 FR 10706), and April 17,1987 (52 FR 12566), EPA proposed
amendments to the double liner and leachate collection system standards
for landfills and surface impoundments. On May 29,1987 (52 FR 20218),
EPA proposed leak detection system requirements for landfills, surface
impoundments, waste piles, and land treatment units. This notice also
proposed to expand the double liner requirement to include waste piles.  On
January 29,1992 (57 FR 3462), EPA issued a final rule on liners and leak
detection systems encompassing all the above proposed rules. How did the
January 29,1992, final rule affect the minimum technological requirements
of RCRA §3004(o)?

ANSWER: The January 29, 1992, Federal Register finalizes EPA's proposed
actions of March 28,1986; April 17,1987; and May 29,1987; and completes
the codification of the minimum technological requirements imposed by
RCRA §§3004(o)(4) and 3004(o)(5)(A).  It also modifies previous liner and
leachate collection and removal system regulations for permitted and
interim status landfills, surface impoundments, and waste piles. In
addition, the  final rule requires owners and operators of these three types
of units to install a leak detection system, establish an action leakage rate,
develop a response action plan, and implement a construction quality
assurance program.

The following landfills, surface impoundments, and waste piles are
affected by this final rule: (1) new units for which construction commences
after January  29,1992; (2) replacement units reused after July 29,1992; and
(3) lateral expansions of units for which construction commences after July
29, 1992. The rule applies to these units regardless of their permit status,
and the Agency maintains that the permit does not act as a shield with
respect to the leak detection requirements (57 FR 3464). The regulations at
40 CFR §270.4 have, therefore, been amended to require that an owner or
operator apply for a permit modification to meet these requirements.

According to  the statute, minimum technological requirements for landfills
and surface impoundments include a double-liner and leachate collection
system, and a leak detection system.  Minimum technological requirements
for waste piles include a leak detection system.  The final rule expanded
the double-liner requirements to waste piles (57 FR 3472).
                                                                                          13

                            "Liners  and  Leak Detection Systems  for  Hazardous Waste
                            Landfills,  Surface  Impoundments, and Waste  Piles" (cont'd)

                            The Agency has determined that a leachate collection and removal system
                            meeting the standards in the final rule fulfills the statutory requirement for a
                            leak detection system. Therefore, a unit's leachate collection and removal
                            system between the top and bottom liners is also its leak detection system.

                            The leak detection system must be designed to detect, collect, and remove
                            leaks at the earliest practicable time. It must be constructed of materials
                            that are compatible with the waste and are strong enough to resist pressure
                            gradients, designed and operated to  minimize clogging, and constructed with
                            a minimum bottom slope of one percent. The drainage layer may be granular
                            or synthetic.  A granular drainage layer must be a least 12 inches thick, and
                            have a minimum hydraulic conductivity of IxlO'^ cm/sec for waste pile and
                            landfill units, or IxlCH cm/sec for surface impoundment units.  Synthetic
                            drainage layers must have a hydraulic transmissivity of 3x10"^ m2/sec for
                            waste pile and landfill units, or 3xlO~4 m2/sec for surface impoundment units.
                            The system requires a sump of sufficient size to collect and remove liquids
                            efficiently and to prevent liquids from backing up into the drainage layer.
                            Variances for alternative system design are available. Landfill and waste
                            pile units also require a  leachate collection  and removal system immediately
                            above the top liner which  ensures that the leachate depth on the top liner
                            does not exceed one foot.

                            The double-liner system  comprises a top and bottom liner. The top liner is
                            the liner directly above the leak detection system. It must be designed to
                            prevent migration of hazardous constituents into the liner during the active
                            life of the unit and during the post-closure period (e.g., a geomembrane
                            liner). The bottom liner must be a composite liner consisting of an upper
                            component (e.g., geomembrane) designed to prevent the migration of
                            hazardous constituents into the liner, underlain by at least 3 feet of
                            compacted  soil material  with a hydraulic conductivity of no more than
                            IxlO"'7 cm/sec.

                            Each unit requires a site-specific action leakage rate and a site-specific
                            response action plan. The action leakage rate is based  on the maximum
                            leakage rate that the leak detection system can remove without the fluid
                            head on the bottom liner exceeding one foot. When the action leakage rate
                            is exceeded, the response action plan must specify actions to be taken to
                            ensure that the leakage does not migrate out of the unit.

                            To ensure that the constructed unit meets or exceeds all design criteria and
                            specifications, a construction quality assurance (CQA) program must be
                            implemented. A CQA program must include a test fill for compacted soil
                            liner components, unless waived.  It also requires a certification by a
                            registered professional engineer that the CQA plan has been successfully
                            carried out and the liner  system meets the design and construction
                            requirements.

"Rebuttable Presumption  for  Used Oil"

QUESTION: According to the recycled used oil management standards in 40
CFR Part 279, any used oil containing more than 1,000 ppm of total halogens
is presumed to have been mixed with a listed hazardous waste and
therefore is subject to RCRA Subtitle C hazardous waste regulation. This
presumption may be rebutted by demonstrating that the used oil does not
contain hazardous waste. According to §279.10(b)(l)(ii), one way to make
this demonstration is to show that the used oil does not contain significant
concentrations of any of the halogenated hazardous constituents listed in
Appendix VIII of Part 261.  What is meant by the term "significant
concentrations"?

ANSWER: There is no regulatory definition of significant concentrations.
The Federal Register of November 29,1985, however, does provide
guidance on the term as it relates to hazardous halogenated solvents.
Specifically, EPA has stated that a level of 100 ppm of individual solvent
compounds is generally considered a significant concentration. Thus, one
may try to rebut the presumption by showing that less than 100 ppm of any
individual hazardous halogenated constituent listed as a hazardous spent
solvent in 40 CFR §261.31 is present (50 FR 49176; November 29,1985).

This 100 ppm level applies only to concentrations of halogenated solvent
constituents and cannot be applied to all hazardous halogenated
compounds. For example, if a used oil contains 1,000 ppm total halogens,
and some of the halogens are pesticide compounds, the presumption of
mixing would not necessarily be overcome by showing that each pesticide is
present at levels less than 100 ppm. Showing that individual hazardous
halogenated solvents are present at levels less than  100 ppm also will not
automatically rebut the presumption, as other site-specific factors must be
considered in making such a determination. For example, if documentation
shows that used oil has been mixed with a listed hazardous waste, that
mixture would be considered a hazardous waste pursuant to the mixture rule
in 40 CFR §261.3(c)(2)(iv), regardless of the level of halogenated
constituents present. (December 1992 Monthly Hotline Report)

"Alcohol-Content  Exclusion  for  the Ignitability Characteristic"

QUESTION:  A generator produces a wastestream with a flash point of 54
degrees Celsius that contains the following three components: water (77
percent), alcohol (13 percent), and a nonalcoholic liquid component (10
percent).  According to the "alcohol exclusion" in 40 CFR §261.21(a)(l), the
characteristic  of ignitability will  not apply to  an aqueous solution that
contains less than 24 percent alcohol and which has a flash point less than
60 degrees Celsius. Does the presence of a nonalcoholic component cause the
aqueous solution to be regulated  as an ignitable waste (D001)?

ANSWER: No, the additional nonalcoholic liquid component will not
cause the wastestream to be regulated as a D001 waste. Despite the
presence of the nonalcoholic liquid component, the wastestream continues to
qualify for the alcohol exclusion  in 40 CFR §261.21(a)(l). According to the
May 19,1980, Federal Register (45 FR 33108), EPA originally intended for
the alcohol exclusion to exempt alcoholic beverages and some types of latex
paints, which exhibit low flash points due to the alcohol content, but do not
sustain combustion because of the high water content. The alcohol exclusion
in 40 CFR §261.21(a)(l), however, is not limited to those wastes mentioned
in the May 19,1980, Federal Register. It applies to all aqueous solutions
containing less than 24 percent alcohol, even if additional nonalcoholic
components are present. EPA clarified in the June 1,1990, Federal Register
(55 FR 22543) that the term "alcohol" in §261.21(a)(l) refers to any alcohol
or combination of alcohols.  The  Agency notes, however,  that if the alcohol
is one of those alcohols specified  in EPA hazardous waste codes F001-F005
and has been used for its solvent properties, the waste must be evaluated to
determine if it should be classified as an F-listed spent solvent waste.

The alcohol exclusion for the ignitability characteristic was adopted from
the Department of Transportation's (DOT) definition of "combustible
liquids" in 49 CFR §173.115(b). The alcohol exclusion in 49 CFR
§173.115(b)(2)(ii) applies to aqueous solutions containing 24 percent or less
alcohol by volume which contain no less than 50 percent water. Since EPA
originally intended to be consistent with DOT regulations when
promulgating the alcohol exclusion in §261.21(a)(l), the 50 percent water
stipulation may be applied to the ignitability characteristic. Therefore,
as clarified  in an internal EPA memorandum, for the purpose of the
ignitability characteristic in §261.21(a)(l), "aqueous" means a solution
containing at least 50 percent water by weight. (July 1992 Monthly Hotline

"'Aqueous'  as Applied to the  Corrosivity Characteristic"

QUESTION: According to 40 CFR §261.22, a solid waste exhibits the
characteristic of corrosivity if it has either of the following properties:

•   It is aqueous and has a pH less than or equal to 2.0 or greater than or
     equal to 12.5 (§261.22(a)(l))

•   It is a liquid which corrodes steel at a rate greater than 6.35 mm
     (0.250 inch) per year (§261.22(a)(2)).

Many aqueous wastes are liquids. Must aqueous liquid wastes be evaluated
for both pH and rate of steel corrosion?

ANSWER: While nonaqueous liquids need only be tested using the steel
corrosion test, aqueous liquids must be evaluated for both pH and rate of
steel corrosion.  If an aqueous liquid has a pH less than or equal to 2.0 or
greater than or equal to 12.5, or corrodes steel at a rate greater than 6.35 mm
per year, it is regulated as a corrosive waste (D002). Therefore even if an
aqueous liquid  passes the §261.22(a)(l) pH test  (pH greater than 2.0 and
less than 12.5), if it corrodes  steel at a rate greater than 6.35 mm per year, it
exhibits the characteristic of corrosivity.

According to  the background document for this  characteristic, Corrosivity
Characteristic: Identification and Listing of Hazardous Waste Under
RCRA Subtitle C, Section 3001. an aqueous waste with a pH between 2.0 and
12.5 may, under certain conditions, corrode steel at a rate greater than 6.35
mm per year.  Several factors influence the rate  of metal corrosion. In
addition to pH, other important factors include temperature,  metal(s)
involved, and aeration and composition of the corrosive medium.

The background document indicates that although alkaline solutions, in
practice, do not severely damage steel, "... a corrosive material with a pH
less than 4.0 will cause iron to dissolve rapidly." In other words, although
an aqueous waste in liquid form that has a pH between 2.0 and 4.0 (i.e., an
acidic solution) passes the pH test, the waste may nonetheless fail  the
steel corrosion test and be regulated as a corrosive (D002) hazardous waste.

Although there is no regulatory definition of the term "aqueous," for
purposes of the corrosivity characteristic an aqueous waste is defined as a
waste for which pH is measurable.  Since not all liquid wastes are in a form
amenable to pH measurement, this operational definition of aqueous
implies that the presence or absence of measurable dissociated hydrogen
ions divides the universe of liquid wastes into two mutually exclusive
categories:  aqueous and nonaqueous.  While all liquid wastes must be
evaluated for rate of steel corrosion, those liquid wastes classified as
aqueous are subject to both the pH and steel corrosion tests. The background
document explains that those who generate or manage a waste can best
determine whether it is in a form suitable for pH measurement, and
therefore an aqueous waste requiring the pH test.

                             (cont'd)

                             This working definition of aqueous means that aqueous wastes can be in
                             nonliquid form.  Suspensions, sols, or gels for which pH is measurable are
                             examples of aqueous nonliquids. The background document for the
                             corrosivity characteristic states that, during a pH determination, the form
                             of the waste should be taken into account. As nonaqueous liquids are subject
                             to the steel corrosion test only, aqueous nonliquids only require evaluation
                             for pH. Therefore, by definition, an aqueous nonliquid with a pH greater
                             than 2.0 and less than 12.5 cannot be regulated as D002, since §261.22(a)(2)
                             applies only to liquids that corrode steel.

                             The operational definition of aqueous for the characteristic of corrosivity
                             differs from the meaning of aqueous as the term applies to the ignitability
                             characteristic. Under §261.21(a)(l), aqueous solutions containing less than
                             24 percent alcohol  by volume are excluded  from regulation as ignitable
                             liquids. In an internal Agency memorandum clarifying this exclusion, an
                             aqueous solution is defined as a solution which contains at least 50 percent
                             water by weight.  Applying this 50 percent water stipulation to define
                             "aqueous" in the context of §261.22(a)(l) is inappropriate. Instead, for
                             purposes of the corrosivity characteristic, aqueous means in a form
                             amenable to pH measurement.  (September 1992 Monthly Hotline Report)

                             QUESTION:  Beryllium is listed in 40 CFR §261.33(e) as an acutely
                             hazardous waste (P015).  Does the P015 listing apply to all forms of unused
                             beryllium that are discarded?

                                The hazardous waste listing P015 applies only to unused commercial
                             chemical product beryllium dust that is discarded  (see §261.33(d) for a
                             definition of commercial chemical product). On May 19,1980, beryllium
                             dust was listed in an interim final rule as an acutely hazardous waste in 40
                             CFR §261.33(e) because of its acute toxicity to humans when inhaled (45 FR
                             33084). The listing was finalized on November 25,1980 (45 FR 78532). In
                             the April 22, 1988, Federal Register, which made technical  corrections to
                             the list of commercial chemical products in §§261.33(e) and (f), the word
                             "dust" was inadvertently omitted from  the listing (53 FR 13382). Despite
                             this omission, the  applicability of the listing remains unchanged. The
                             April 22, 1988, Federal Register was intended only to amend certain
                             typographical errors in the hazardous waste lists. EPA never proposed to
                             change the listing from "beryllium dust" to "beryllium" and does not intend
                             the listing to apply to beryllium.  Therefore, despite this typographical
                             error in 40 CFR §261.33(e), the scope of the listing remains unchanged, and
                             the hazardous waste code P015 applies only to beryllium dust. (November

"Commercial  Chemical Product  Definition  in  §261.33"

QUESTION: A manufacturer intends to discard an unused formulation
which contains two chemicals that serve as active  ingredients. Only one of
the chemicals is listed in 40 CFR §261.33.  A comment in §261.33(d) states
that "[t]he phrase 'commercial chemical product or manufacturing
chemical intermediate having the generic name listed in...1 refers to a
chemical substance which is manufactured or formulated for commercial or
manufacturing use and which consists of the commercially pure grade of the
chemical, any technical grades of the chemical that are produced or
marketed, and all formulations in which the chemical is the sole active
ingredient." (Emphasis added.) Does the term "sole active ingredient"
refer only to chemicals which  are listed in §§261.33(e) and (f)? If a product
contains two active ingredients, only one  of which is listed, would the
discarded product be regulated as a P- or U-listed  waste?

ANSWER: The discarded formulation would not be regulated as P- or U-
listed waste when discarded. In order to  be regulated as a P- or U-listed
waste, a waste must meet all of the listing criteria. The listings in §261.33
do not include chemical mixtures where the listed chemical is not the sole
active ingredient, and do not apply to chemicals that have been used for
their intended purpose (54 FR 31335; July  28,1989). In the scenario
described above, while the discarded formulation meets the criterion of
being unused, it contains more than one active ingredient.  It is not necessary
for a chemical to be listed in §§261.33(e) or (f) in order to meet the
definition of an active ingredient.  An active ingredient is  defined as a
compound or mixture that performs the function of the product. "Sole active
ingredient" means the active ingredient is the only chemically active
component for the function of the product. If a formulation has more than
one active ingredient, the formulation, when discarded, would not be
within the scope of the listing in §261.33,  regardless of whether only one or
both active ingredients are listed.

Generators, however, must be sure to correctly determine whether a
particular constituent performs the function of the product, or only serves an
ancillary function, such as mobilizing or preserving the active ingredient.
For example, fillers, solvent carriers, propellants, and other components
with no pesticidal role are functionally inert in pesticide formulations and
therefore are not active ingredients. In cases where a hazardous constituent
from §§261.33(e) or (f) is a functionally inert component of  a commercial
chemical product, e.g., a solvent carrier, its presence does not prevent the
formulation containing another P- or U-listed constituent as the sole active
ingredient from being a P- or U-list waste (internal Agency memorandum
dated May 3,1989). (March 1992 Monthly Hotline Report)

"Filters  Used  to  Reclaim  CFC Refrigerant"

QUESTION:  While servicing air conditioners, a facility generates spent
CFC-11 which exhibits the toxicity characteristic for carbon tetrachloride
(D019). The generator reclaims the used refrigerant for subsequent reuse,
and during the reclamation process generates contaminated filters which
also exhibit the TC for carbon tetrachloride.  According to §261.4(b)(12),
the used CFC refrigerant is exempt from the definition of hazardous waste
if it is going to be reclaimed for further use.  If the spent filters are being
discarded, would they also be excluded from regulation as a hazardous
waste under §261.4(b)(12) since they are generated by the reclamation of an
excluded waste?

ANSWER: As explained in the February 13,1991, Federal Register (56 FR
5910), the purpose of the exclusion provided in §261.4(b)(12) is to encourage
the recycling and reuse of CFC refrigerants and discourage the practice of
venting them to the air. Wastes derived  from the CFC reclamation process
itself, however, are not exempt, and the filters would not be covered by the
exclusion. Since the filters exhibit the toxicity characteristic, they must be
managed as hazardous waste. Any other residues generated by the
reclamation process would also need to be evaluated for characteristics,
either through testing or application of knowledge.  (September 1992

"Hydrochlorofluorocarbons  Used in  Degreasing"

QUESTION:  According to 40 CFR §261.31, chlorinated fluorocarbons
(CFCs) used in degreasing are classified as FOOl.  EPA included CFCs used in
degreasing in the FOOl listing because of concern for their potential
contribution to the depletion of stratospheric ozone. Are
hydrochlorofluorocarbons (HCFCs) used in degreasing also regulated as
FOOl?
                             ANSWER: Because the FOOl listing description includes all chlorinated
                             fluorocarbons, hydrochlorofluorocarbons used in degreasing operations are
                             also classified as FOOl. Of course, the solvent formulation must meet the 10
                             percent (by volume) before-use criterion in the FOOl listing. Hydrogenated
                             fluorocarbons (HFCs), however, are not included in the scope of the FOOl
                             listing.  (December 1992 Monthly Hotline Report)

"Lead Used as  Shielding in Low-Level  Radioactive Waste
Disposal"

QUESTION: A generator of low-level radioactive waste places the waste
in lead or lead-lined containers.  These containers, used to dispose of
radioactive waste, also serve as  shielding. Would the containers, once
disposed of in a landfill, be regulated as a mixed waste under both RCRA
(because the containers exhibit  the toxicity characteristic for lead) and the
Atomic Energy Act (because they contain radioactive waste)?

ANSWER:  No, the containers or container liners would not be regulated as
a mixed waste if their primary use is for shielding in disposal operations.
Because the containers would be fulfilling their intended  use and thus
would not be considered discarded under RCRA, they do not meet the
definition of a solid waste (40 CFR §261.2(c)(l)(ii)).  Since the containers
would not meet the definition of solid waste, they would not meet the
definition of hazardous waste. A 1987 internal Agency memorandum states,
"[i]n this instance, containers or liners may be analogous to commercial
chemical products (e.g., pesticides) where as a product, their normal use is
placement on the land. Therefore, lead whose primary use is shielding in
low-level waste disposal operations is not subject to Federal hazardous
waste regulations when placed on the land as part of its normal  commercial
use." In this example, the containers are not subject to RCRA and are not
regulated as mixed waste. The radioactive waste would, however, be
subject to any applicable Atomic Energy Act regulations.

EPA notes, however, that "...lead containers and liners may be equally
hazardous to human health and the environment when placed in the
ground independent of [the] legal classification as a waste or container.
Therefore, EPA recommends that all lead containers and lead liners be
managed in an environmentally  safe manner (e.g., managed in a permitted
hazardous waste facility or treated such that  it no longer exhibits its
characteristic)" (OSWER Directive 9432.00-2; October 4, 1989).  (May 1992

"Perchloroethylene  Used in  Dry Cleaning"

QUESTION:  A dry cleaner uses a 50 percent perchloroethylene
(tetrachloroethylene) mixture in her cleaning process.  Since
tetrachloroethylene appears in the listing descriptions for both F001 and
F002, would the spent solvent mixture be classified as F001 or F002?

ANSWER: Spent tetrachloroethylene used in dry cleaning is classified as
F002 (40 CFR §261.31).  The background listing document for F002 identifies
certain industries that generate spent halogenated solvents meeting the
F002 listing (Identification and  Listing of Hazardous Waste, 55261.31 and
261.32 -- Listing of Hazardous Waste, page 41).  According to this document,
tetrachloroethylene used in laundry and dry cleaning operations is
regulated as F002. Of course, the spent solvent formulation must meet the 10
percent (by volume) before-use criterion in the F002 listing. Furthermore,
the F001 listing is, by its terms, limited to spent solvents "used in
degreasing."  (October 1992 Monthly Hotline Report)

"Reclaimed  Commercial Products:  Regulatory  Status"

QUESTION: The owner of a facility collects used railroad ties that were
treated with a wood preservative containing creosote.  When the owner has
accumulated a sufficient amount of railroad ties he bakes them to draw out
the creosote. Once this process is  complete, the reclaimed creosote can be
used as a wood preservative without further processing. A drum of this
creosote leaked into the soil. How is the resulting contaminated soil
regulated upon disposal?

ANSWER: The creosote-contaminated soil must be managed as U051.  The
recovered creosote formulation is classified as a product because the
creosote has been reclaimed from the railroad ties and requires no
additional processing before it can be beneficially used (40 CFR 261.3(c)(2)).
Upon leaking into the soil, the creosote  is classified as a solid waste
pursuant to §261.2(b). The generator must then determine whether this
solid waste is a hazardous waste.  Sections 261.33(e) and (f)  designate
certain commercial chemical products as hazardous wastes when discarded.
Specifically, §261.33(d)  defines  commercial chemical product in part as
any commercial or technical grade of a product, or any formulation in which
the listed chemical is the  sole active ingredient. Assuming  the reclaimed
creosote is the only chemically active component for the function of the
wood preservative (i.e., the sole active ingredient), and  the discarded
material meets the definition of a solid  waste per §261.2(b), the discarded
creosote is classified as U051.  Since the soil is contaminated with U051, it
is subject to regulation as  a hazardous waste in accordance with EPA's
"contained-in" policy, which requires all media (i.e., debris, soil,
groundwater, sediment) that contain listed hazardous wastes to be
managed as listed hazardous wastes. The soil, therefore, would have to be
handled as a  hazardous waste (U051) until it is decontaminated or until
the hazardous waste is  delisted (see, for example, 56 FR 24444, 24456;
May 30,1991). (November 1992 Monthly Hotline Report)

Key Words:

Bevill; oil; transportation
QUESTION: An oil production facility uses gathering pipelines to
transport oil from its production site to a site owned by another facility.
The oil has already undergone initial oil/water separation.  Waste forms
in the gathering lines during the transportation of the oil. Is the waste
that forms subject to the hazardous waste exclusion at 40 CFR §261.4(b)(5)?

ANSWER: The answer depends on the ownership of the oil at the time the
waste forms.  Section 261.4(b)(5) excludes drilling fluids, produced waters,
and other wastes associated with the exploration, development, or
production of crude oil, natural gas, or geothermal energy from the
definition of hazardous waste.  Waste generated after legal custody of the
oil changes hands during transportation will not meet the exclusion because
it is not intrinsic to the exploration, development, or production of crude oil.

The July 6,1988, Federal Register (53 FR 25446, footnote 1) defines
associated wastes as those wastes other than produced water, rigwash, and
drilling muds and cuttings that are intrinsic to exploration, development,
and production of crude oil and natural gas. The Report to Congress:
Management of Wastes from the Exploration, Development, and Production
of Crude Oil. Natural Gas, and Geothermal Energy, VOL 1 of 3  (EPA/530-
SW-88-003-A, Dec. 1987) states on page 11-17 that "[t]he phrase
'intrinsically derived from the primary field operations' is intended to
differentiate exploration, development, and production operations from
transportation (from the point of custody transfer or of production
separation and dehydration) and manufacturing operations." Accordingly,
any waste generated after a change in the custody of the oil, or, in the
absence of the change  in custody after the initial oil/water separation, is
not subject to the §261.4(b)(5) hazardous waste exclusion because it is not
intrinsic to the exploration, development, or production of crude oil.

                             FR 619) discusses this exclusion and states that "[w]hen secondary

                             materials are functioning as raw materials...and, thus,  are not wastes." A

                             substitute for a commercial product is not being directly used (or reused), and
                             so would not qualify for this exclusion. (May 1992 Monthly Hotline Report)

"Speculative Accumulation Calculation"

QUESTION:  In March 1991, a facility generated 200 kg of sludge that
exhibited the  toxicity characteristic (TC) for lead (D008). The operator of
the facility placed these materials in storage to await reclamation of lead.
At that time, the facility was not accumulating any other recyclable
materials.  Since the sludge will be reclaimed, it is not considered a solid
waste while stored prior to reclamation (40 CFR §261.2(c)(3)). On
December 31, 1991, the facility still had not recycled any of this material.
Is the sludge accumulated speculatively under §261.1(c)(8), since 75 percent
was not recycled in the year, and therefore subject to management as a solid
and hazardous waste?

ANSWER: No, the sludge would not be accumulated speculatively.
Although it is accumulated before being recycled, it is not accumulated
speculatively  if the person accumulating it can show that (1) the material
is potentially recyclable and has a feasible means of being recycled, and (2)
during the calendar year (commencing on January 1) the amount of material
that is recycled or sent for recycling equals at least 75 percent of the amount
of  that material accumulated at the beginning of the period (§261.1(c)(8)).
A facility owner/opera tor must show that he or she has recycled 75 percent
of  the material in storage on January 1 of that year.  "Under this provision,
the amount of material turned over in a year is critical, not the total
amount accumulated at the end of the year" (48 FR 14490; April 4,1983).

                           For the above facility, the amount of material in storage on January 1,1991,
                           was zero, so on December 31,1991, the operator does not have to show that
                           any amount was recycled during the calendar year. On January 1,1992,
                           however, 200 kg of D008 sludge are in storage. Thus, the facility must be
                           able to show that 75 percent of this material, or 150 kg, has been recycled or
                           sent for recycling by December 31,1992. If the operator cannot demonstrate
                           this 75 percent recycling rate, the sludge remaining in storage is said to be
                           accumulated speculatively and becomes subject to regulation as a solid
                           waste. Because it exhibits a characteristic, the generator must begin to
                           handle the material  as a hazardous waste. The Agency notes  that "this
                           approach could allow essentially a free year to accumulate where a
                           generator starts a year with little or no waste" (48 FR 14490; April 4, 1983).
                           The period of one calendar year starting on January 1 was selected,
                           however, to facilitate enforcement and achieve uniformity (50 FR 635;
                           January 4,1985).

                           In making the above calculation, the 75 percent requirement applies to all
                           materials of the same class being recycled in the  same way. If this facility
                           also generated a by-product that exhibited the TC for chromium (D007)  and
                           reclaimed  it, the owner/operator would make a separate speculative
                           accumulation calculation for this by-product (50 FR 635-6; January 4,1985).

                           The RCRA regulations provide that certain materials, which would
                           otherwise be considered hazardous waste, will not be regulated as solid
                           waste (and therefore hazardous waste) when they are reclaimed
                           (§261.2(c)(3)). The requirement that  materials accumulated speculatively
                           be regulated as solid waste was  intended to prevent abuse of this
                           exemption. It is only applicable to certain situations, including the
                           reclamation of characteristic sludges and by-products, materials used or
                           reused as ingredients, commercial product substitutes,  black liquor, sulfuric
                           acid, and precious metals reclamation. The rule is not applicable to spent
                           materials being reclaimed, listed sludges being reclaimed, or listed by-
                           products being reclaimed, because these materials are already considered
                           solid wastes when awaiting recycling (50 FR 635; January 4,1985). It also
                           does not apply to commercial chemical products that are stored prior to
                           reclamation, because, by definition, these materials are not regulated as
                           solid wastes until they are abandoned or intended for discard (48 FR 14489;
                           April 4, 1983). (February 1992 Monthly Hotline Report)

QUESTION: According to 40 CFR §§264.1 (g)(6), 265.1(c)(10), and
270.1(c)(2)(v), wastewater treatment units (WWTUs) as defined in §260.10
are exempt from Parts 264/265 permitted and interim status requirements
for treatment, storage, and disposal facilities.  If the WWTU itself is
exempt from Subtitle C regulation, what is the status of the hazardous
waste that it treats?

ANSWER: As stated in an internal Agency memorandum, "[o]nly the
wastewater treatment unit (i.e., the tank) is exempt; the exemption does
not 'follow' or attach to the waste." Consequently, all applicable
hazardous waste management standards apply to the waste prior to
treatment in  the WWTU, and to any residue generated by the treatment of
that waste. In other words, solid waste resulting from the treatment of a
listed hazardous waste in an exempt WWTU will remain a listed
hazardous waste, and solid waste resulting from the treatment of a
characteristic hazardous waste in an exempt unit will remain hazardous as
long as the solid waste continues to exhibit a characteristic (§§261.3(c)
and (d)). (June 1992 Monthly Hotline Report)

QUESTION: Should regulations promulgated pursuant to the Occupational
Safety and Health Act (OSHA) be designated as applicable, relevant and
appropriate requirements (ARARs) during the selection of a Superfund
remedy?  Must workers at a CERCLA site comply with OSHA regulations?

ANSWER:  OSHA requirements are directly applicable under NCP (40 CFR
§300.150), and should not be designated as an ARAR. CERCLA §121(d)(2)
states that when determining cleanup levels, applicable  or relevant and
appropriate requirements may be drawn from any Federal environmental
law or any State environmental or facility siting law that is more stringent
than any Federal standard. The National Contingency Plan states that,
"...EPA believes that OSHA is more properly viewed as an employee
protection law, rather than an 'environmental' law, and thus the  process in
CERCLA §121 (d) for the attainment or waiver of ARARs would not apply
to OSHA standards" (55  FR 8679; March 8, 1990).

Workers at CERCLA  sites, however, must comply with certain OSHA
standards. CERCLA  §lll(c)(6) and SARA §126 charged  the Department of
Labor (DOL) with writing health and safety regulations that would apply
to workers responding to emergency releases of hazardous substances or
engaged in hazardous waste operations. In response, DOL developed the
OSHA employee protection regulations found at 29 CFR §1910.120. These
requirements were then incorporated by reference into the CERCLA
regulations at 40 CFR §300.150.

Other OSHA employee protection regulations which have not been
specifically incorporated into CERCLA regulations may also apply to
CERCLA sites.  For example, 29 CFR §1910.180(b) established specific
safety regulations pertaining to lifting cranes. These regulations  would
have to be complied with during a site remediation requiring the  use of a
crane, but would not be designated as ARARs. CERCLA site workers would
be required to comply because of DOL's authority to regulate the
workplace, not because of CERCLA requirements. (June 1992 Monthly

Key Words:

Construction completion;
de-linking policy; National
Priorities List
QUESTION:  What is the significance of the Construction Completion
category on the National Priorities List (NPL), and how was it affected by
recent modifications to the NPL deletion process?

ANSWER: EPA realized that the number of sites deleted from the NPL
did not accurately reflect the amount of Superfund work completed and the
extent of threats actually mitigated at Superfund sites. Due to the frequent
need to conduct complex, long-term remedies and the stringent regulatory
deletion criteria, sites must remain on the NPL despite the fact that
extensive remedial actions have taken place and the site may no longer
present a threat to human health and the environment. In order to more
accurately communicate progress toward cleaning up NPL sites, EPA
established (1) the Construction Completion category, which allows EPA to
specifically designate sites that are in the final stage of the remedial
process, and (2) a policy change which facilitates more rapid deletion of a
site from the NPL when cleanup is complete.

On March 8,1990 (55 FR 8699), EPA promulgated the revised National
Contingency Plan (NCP), which stated that EPA had the authority to
place NPL sites into designated categories (40 CFR §300.425(d)(6)).  This
new regulatory language prompted the establishment of  the Construction
Completion category, which consists of sites that are close to being deleted.
The category included (1) those sites for which a Notice  of Intent to Delete
had been published; (2) sites awaiting the five-year review required by
CERCLA §121(c) after the completion of a remedial action; and (3) sites
undergoing long-term remedial actions (primarily groundwater cleanups) at
which the construction phase of the activity is complete.

The Construction Completion category no longer includes sites that are
awaiting the five-year review; EPA removed that requirement from the
deletion process (56 FR 66601). For several years, EPA's policy was to
retain sites on the NPL until it completed a review five  years after
initiation of the remedial action. The review was to confirm that the
remediation is protective of human health and the environment.  Although
CERCLA §121 (c) requires that a five-year review take place, the statute
does not specify that the review must take place prior to NPL deletion.
The decision to delay deletion until after the five-year review arose from
the EPA Administrator's June 1989 Management Review of the Superfund
Program (also known as the "90-Day Study"). Subsequent experience and
28

-------
                      SUPERFUND  (SF)
"National  Priorities List Construction  Completion Category  and
Site  Deletion"  (cont'd)

analysis have shown that including the five-year review as part of the
NPL deletion criteria was confusing to the public.  Inclusion meant that
even though many sites no longer presented a health threat and were
otherwise eligible for deletion, the sites had to remain on the NPL.  EPA
determined that the Superfund program would operate more efficiently if
the NPL deletion process and the five-year review process were separated,
or "de-linked." On December 24,1991, EPA published the de-linking
policy, stating that deletion is no longer deferred pending the completion of
the five-year reviews. This change allows sites to be deleted from the NPL
as soon as the requirements specified in the Record of Decision are met.
Sites may be restored to the NPL immediately, if deemed necessary, at the
time of the five-year review.

EPA first placed sites into the Construction Completion category when the
February 11, 1992, NPL final rule was published (56 FR 5598). At that time,
14 NPL sites were given the special classification.  On January 16,1992,
EPA issued a Federal Register notice clarifying the Construction
Completion designation  and placing an additional 11  sites into the category
(57 FR 1873). This designation does not exempt a site from the deletion
procedures found at 40 CFR §300.425(e), but does signify that major progress
has been made at the site.  In order for a site to be shifted into the
Construction Completion category, the site must have an approved interim
or final close-out report.  Thus, the Construction Completion category
consists of (1) sites with  an operating remedy in place that will take many
years to complete (such as groundwater pump-and-treatment), and (2)  sites
that are cleaned up and will most likely be deleted when the required
public notice and State consultation process has been completed.

Separating the five-year  review requirement from the deletion process and
placing sites into the Construction Completion category are procedural
changes that do not affect implementation of the regulations. The
importance of these policies is that they streamline the deletion process,
and highlight the NPL sites where health risks have been significantly
reduced.  These changes should provide a more effective method of
demonstrating to the public the progress and achievements of the Superfund
program. (March 1992 Monthly Hotline Report)

"Off-Site Policy  and  Subtitle  D  Regulations"

QUESTION:  A CERCLA site is undergoing remediation, which is producing
soil and debris. Analysis of the soil and debris indicates they do not
contain RCRA hazardous waste (i.e., they are nonhazardous waste).  Due to
the conditions at the site, however, the soil and debris will have to be
disposed of off-site. Is it permissible under the existing CERCLA off-site
policy (OSWER Directive 9843.11, November 13, 1987, PB91-139 287) to
dispose of nonhazardous soil and debris from a CERCLA site at a  municipal
solid  waste landfill regulated by RCRA Subtitle D?

ANSWER: If nonhazardous waste generated during remediation of a
CERCLA site is not otherwise regulated (i.e., by the Toxic Substances
Control Act, the Atomic Energy Act, or other applicable Federal and state
laws), a lead agency can direct this waste to be disposed of at a Subtitle D
municipal solid waste landfill facility that meets the requirements set by
the November 13, 1987,  off-site policy. The off-site policy, promulgated
pursuant to CERCLA §121(d)(3), provides  that CERCLA hazardous
substances, pollutants, and contaminants (CERCLA waste) transferred off-
site are sent only to facilities determined to be environmentally sound.

To meet the objectives of the off-site policy,  the lead agency must make a
determination about the acceptability of the facility that  is to receive the
CERCLA waste. To be considered acceptable to receive CERCLA  waste
under the off-site policy, a Subtitle D facility must be in compliance with
all applicable Federal or state regulations, and all environmentally
significant releases from the Subtitle D facility must be controlled by a
corrective action program under the applicable Federal  or state authority.
To ensure compliance with these standards, facilities designated to receive
CERCLA wastes must be inspected by the appropriate regulatory agency
prior  to the planned receipt of CERCLA waste. Information about the
acceptability  of a particular facility to receive CERCLA waste may be
obtained by calling the Regional Off-Site Coordinator (ROC) of the Region
in which  the facility  is  located.

The regulatory authority for municipal solid waste landfills rests
primarily with state and local governments. In October 1991, EPA
promulgated  a rule requiring owners and operators of Subtitle D municipal
solid  waste landfills to comply with a comprehensive set of Federal
minimum standards (56 FjR 50978; October 9,1991). Owners and operators
must  comply with these new requirements by October 9,1993. These
regulations, which include  location restrictions,  facility  design and
operating criteria, groundvvater monitoring and corrective  action
requirements, financial assurance requirements, and closure and post-closure
care requirements,  are codified at 40 CFR Fart 258.  (August 1992 Monthly

"Removal Activities  Considered  in  HRS  Scoring"

QUESTION: Part of a site has been cleaned up prior to the calculation of a
Hazard Ranking System (HRS) score. Can the contamination that was
removed be eliminated from inclusion in the HRS calculation?

ANSWER:  The HRS, which  evaluates threats to human health and the
environment from hazardous waste sites, is the principal mechanism for
placing uncontrolled hazardous waste sites on the National Priorities List
(NPL).  In certain circumstances it is possible for contamination that has
been removed prior to HRS scoring to be excluded from the calculation.

The original HRS (47 FR 31180; July 16, 1982) based the evaluation of
scoring factors on initial site conditions that existed prior to any response.
Pursuant to SARA §105(c), EPA proposed to revise the HRS methodology
(53 FR 51962; December 23, 1988). In the revised HRS, which was finalized
on December 14,1990 (55 FR 51532), EPA changed its policy to allow
calculation of waste quantities  to be based on current conditions. Reductions
in quantity of waste through timely removal actions are now considered in
the calculation of the HRS score. The Agency believes that when
implemented correctly, consideration of removal actions in HRS scoring is
likely to increase incentives for rapid, early action by responsible parties.
Early cleanup actions reduce risks to the public and allow for more cost-
effective expenditure of the fund.

A response action must meet three criteria to be considered a  "qualifying
removal" for HRS purposes: (1) wastes must have been physically removed
from the site; (2) those wastes  must be disposed of or destroyed at a facility
permitted under RCRA, TSCA, or the NRC; and (3) the removal action must
have occurred  prior to the cutoff date applicable to the site (which
corresponds to the start of the site inspection at the site).  The first
criterion, physical removal, is  required to ensure that the effects of
responses not reducing waste quantities (such as providing alternate
drinking water supplies or relocating citizens) are not considered in
calculating an HRS score (55 FR 51568). In such cases, EPA believes the
initial contamination should be considered in scoring sites, so  the HRS score
will reflect remaining impacts. The second criterion, disposal in an
appropriate facility, ensures that wastes and their associated risks are not
simply moved from one uncontrolled location to another. The criterion
pertaining to the timing of the action ensures that EPA does not have to
recalculate site scores continually to reflect removal actions. To do so would
be unduly burdensome, and would disrupt the site assessment process.

                             "Removal Activities Considered  in HRS  Scoring"  (cont'd)

                             In calculating HRS scores, EPA will only consider qualifying removal
                             actions conducted prior to the start of a site inspection (SI). The SI start
                             date is also referred to as the cutoff date applicable to the site. Because of
                             the difference in site assessment activities for different types of sites (e.g.,
                             EPA-lead, State-lead, Federal  facilities), criteria for determining the
                             appropriate cutoff date differ among sites.  For Federal facility sites, the
                             cut-off date is 18 months after the site is placed on the Federal Facilities
                             Docket. For non-Federal facility sites, the Agency historically has not
                             tracked SI dates, so the SI cutoff date may be determined by several
                             analogous events.  Generally, the SI cutoff date for non-Federal facility
                             sites is the date that the workplan development for the first SI began. The
                             Agency now tracks SI start dates in CERCLIS; thus the SI start date entered
                             in CERCLIS will be used with increasing frequency in the future.

                             For sites with multiple Sis,  the SI cut-off date is keyed to the first SI;
                             however, EPA may establish a later cutoff date under certain
                             circumstances.  For example, if a wholesale change in site sampling
                             strategy occurs, considering removals is unlikely to disrupt the site
                             assessment process. EPA may also consider establishing a  later cutoff date
                             if the SI process lasts for more than four years. Follow-up sampling
                             conducted to gather information for the revised HRS should not be used to
                             determine a new cutoff date, even if more than four years have elapsed,
                             because the bulk of the sampling generally will have been conducted
                             previously.

"Core Program Cooperative  Agreements"

QUESTION: What are Core Program Cooperative Agreements?

ANSWER: CERCLA §104(d)(l) authorizes EPA to award cooperative
agreements with States, political subdivisions, and Federally recognized
Indian tribes. A Core Program Cooperative Agreement (CA) is a legal
instrument EPA can use to transfer funds to a State, Federally recognized
Indian tribe, or a State's political subdivision to support CERCLA
implementation activities. EPA intends the Core Program to help lay the
groundwork for the implementation of the integrated EPA-State/tribe
approach to meeting Superfund goals.

The regulations regarding State, political subdivision,  and Federally
recognized Indian tribe involvement in the Superfund program are found in
the National Contingency Plan at 40 CFR §300.515. The requirements for
CAs are discussed in the June 5,1990,  Federal Register (55 FR 22994), and
codified at 40 CFR Part 35, Subpart O, Cooperative Agreements and
Superfund State Contracts for Superfund Response. These funds are not
assignable to specific sites, but are intended to develop and maintain
participation in the CERCLA response program.  All activities that are not
site-specific and that are necessary to  support a recipient's Superfund
program are eligible for Core Program funding.  Examples include the
development of recordkeeping systems, the general coordination of
administration and/or management activities associated with removals,
and the development of a 20-year State Waste Capacity Assurance Plan.
The number of Core Program CAs has  increased from 3 in 1987 to 46 in 1991.
States are required to provide a 10 percent cost share for Core Program
awards. (January 1992 Monthly Hotline Report)

"Interest  Rates  on Superfund Cost  Recovery Actions"

QUESTION:  EPA is authorized by CERCLA §111 to expend Superfund
monies to finance response actions in order to facilitate cleanup of Superfund
sites. The Agency can then take enforcement action to recover costs from
potentially responsible parties (PRPs) at the site pursuant to §107.  When
calculating recoverable costs, may EPA charge interest on the amount
expended? If so, how is the applicable interest rate calculated?

                            ANSWER: EPA is authorized to seek interest charges on all amounts
                            recoverable under CERCLA §107(a)(4). Recoverable amounts under
                            §107(a)(4) include costs not inconsistent with with the National
                            Contingency Plan which are incurred during the process of conducting a
                            removal action, remedial investigation/feasibility study (RI/FS), or
                            remedial design and remedial action activity (RD/RA). In addition,
                            §107(a)(4) authorizes EPA or other Federal agencies to recover damages for
                            injury to, destruction of, or loss of natural resources, and the costs of any
                            health assessment or health effects studies carried out under §104(i). EPA
                            may also recover its oversight costs, legal costs, and indirect costs in
                            accordance with CERCLA authorities.

                            The interest EPA seeks from PRPs on outstanding debts from monies spent to
                            clean up Superfund sites, as well as the interest EPA earns on the fund
                            itself, are determined by the Treasury Department each year using a one-
                            year constant average  of interest rates paid on U. S. Treasury MK bills. The
                            interest rates for fiscal years 1985 through 1992 are as follows:
1985
1986
1987
1988
10.82%

8.47%
7.99%
5.70%
                             Each fiscal year begins on October 1 and ends on September 30 of the
                             following year. When calculating cost recovery amounts, EPA applies the
                             interest rate from the date EPA issues a demand letter or the date of any
                             fund expenditure. Even if EPA has not made a specific demand for payment,
                             interest is still recoverable from the date EPA incurred the costs (see U.S. v.
                             Bell Petroleum Services, Inc., 734 F. Supp. 771, 784). If a cost recovery action
                             takes place over a number of years, interest on the outstanding balance is
                             recalculated using the new fiscal year's interest rate until EPA receives full
                             payment. (July 1992 Monthly Hotline Report)

QUESTION: What is the process for distributing and accessing Superfund
publications?

ANSWER: There are several sources for Superfund documents and document

National Technical Information Service (NTIS), and the Public
Information Center (PIC).  Each resource plays a different role in the
distribution of Superfund documents and information.

"Accessing Superfund  Publications"  (cont'd)

The Superfund Document Center is the primary source of Superfund
documents for EPA staff. It is also the Office of Emergency and Remedial
Response's (OERR's) official publication clearinghouse and, as such, sets
publication standards for all Superfund documents. The Document Center
reviews the document preparation process with authors, ensures that the
document conforms to OERR standards, and coordinates reproduction,
printing, and distribution. The Superfund Document Center houses
Superfund program documents (series 9200-9300) and Enforcement program
documents (series 9800-9900), and has organized these documents into a
catalog entitled Compendium of Superfund Program Publications, which
includes brief summaries of individual documents. The Superfund Document
Center can distribute documents to EPA employees only.

The Superfund Docket is the public viewing location for rulemaking
materials that support the Office of Solid Waste and Emergency Response's
Superfund program. These rulemaking materials include Superfund Federal
Register notices, public comments, the Agency's response to comments, and
background reference materials. The Comprehensive Environmental
Response, Compensation, and Liability Act of 1980 as amended by the
Superfund Amendments and Reauthorizetion Act of 1986 is available for
viewing at  the Superfund Docket.  National Priorities List site
documentation, including Records of Decision, Hazardous Ranking System
scoring  packages, and Administrative Records, are also located at the
Superfund Docket. The Superfund Document Center (Room M-2514) and the
Superfund Docket (Room M-2427) are located at: U.S. EPA, 401 M Street,
SW, Washington, DC 20460.  Hours of operation are 9:00 a.m. to 4:00 p.m.,
Monday through Friday.

In order to be responsive to extensive public demand, EPA has placed all
current, publicly available Superfund documents with NTIS for
distribution. Because NTIS receives no  Congressionally appropriated
funds, the public must purchase  these documents.  For information about the
full range of available Superfund documents, the Compendium of Superfund
Program Publications (Order No. PR-881) is available free of charge from
NTIS.* Those documents added to the Superfund collection since the
preparation of the Compendium may be searched on line in the NTIS
Bibliographic Database, which  is available through several of the
commercial database vendors. The new NTIS standing-order service is the
best way to stay current  with Superfund program developments. (April
1992 Monthly Hotline Report)

*Addition:  The compendium, which is published annually, is
supplemented by a quarterly update bulletin also available at NTIS for no
charge.

"Community  Environmental  Response Facilitation  Act"

QUESTION: On October 19,1992, Congress amended CERCLA §12(Xh)
under the Community Environmental Response Facilitation Act (Public Law
102-426) to expedite the sale of federal land that is determined to be
uncontaminated. What are the provisions of this amendment?

ANSWER: Congress passed the Community Environmental Response
Facilitation Act (CERFA) in response to concern over the adverse economic
conditions that often result from the closing of certain federal facilities.
Transferring federal property to the private sector is often a lengthy
process due to the concern over possible hazardous substances on the
property, and the delay in remediating environmental contamination. The
purpose of CERFA is to identify federal land and properties offering the
greatest opportunity for reuse and redevelopment, expedite necessary
remedial and corrective actions,  make the property available for sale, and
ensure the continued liability of the federal government when appropriate.

Under §120(h) of CERCLA, whenever the U.S. government enters into a
contract to sell or transfer federal property, a notice  must be placed in the
contract for sale reporting any hazardous substance  that has been stored for
a year or more, known to be released, or was disposed of on the property.
When the government sells property, a similar notice must be placed in the
deed, as well as a  covenant that all necessary remedial action has been
taken by the time of the transfer. EPA promulgated regulations at 40 CFR
Part 373 specifying the content of the notice (55 FR 14208; April 16,1990).
CERFA adds to the provisions of §120(h) by requiring the federal
government, within specified deadlines, to identify "uncontaminated"
property where hazardous substances or petroleum products have not been
released, disposed of, or stored for more  than a year.

This identification process includes a detailed search of federal
government records and  title documents; aerial photographs; a visual
inspection; a physical inspection; reasonably obtainable federal, state, and
local records of adjacent facilities; interviews with current or former
employees; and sampling, if appropriate. The EPA Administrator or the
appropriate state official must concur with the results of the identification
at NPL and non-NPL sites, respectively.  Pursuant to §120(h) of CERCLA,
the sale of the property will not  terminate the federal government's
liability.  CERFA stipulates that any undiscovered  environmental
problems with respect to any hazardous substances, petroleum, or petroleum
derivatives present on the property at the time of the sale or transfer of the
property remain the responsibility of the federal government and provides
that deeds must contain access provisions to allow for such response actions.

                            Section 120(h)(3)(B) requires that each deed for transferred federal
                            property contain a covenant warranting that "all remedial action" has been
                            taken with respect to any hazardous substance remaining on the property.
                            Section 4 of CERFA specifies that all remedial action has been taken when
                            the construction and installation of an approved remedial design has been
                            completed.  The federal agency must demonstrate that the remedial design
                            is operating properly and successfully.  (December 1992 Monthly Hotline

"Reportable Quantity for Metallic Compounds  Under the CAA
Amendments"

QUESTION: CERCLA §103(a) requires any person in charge of a vessel or
facility, upon learning of any release of a hazardous substance in quantities
equal to or exceeding a reportable quantity (RQ) in a 24-hour period, to
immediately notify the National Response Center. EPA determines
appropriate RQs for every hazardous substance designated pursuant to
CERCLA §101(14), and codifies these quantities at 40 CFR §302.4. The
Agency did not establish RQs for many generic classes of metallic
compounds (e.g., nickel, mercury, and lead compounds) because it would be
virtually impossible to develop standard RQs that would take into account
the varying characteristics of all the specific  compounds within each class
(50 FR 13461; April 4,1985). Therefore the CERCLA reporting requirements
are triggered by the release of a specific compound listed in 40 CFR §302.4,
but not by a release of these generic classes of compounds.

Pursuant to CERCLA §102(b), substances added to the hazardous substance
list receive a statutory RQ of one pound until EPA designates a final RQ.
The 1990 amendments to §112 of the Clean Air Act designated a group of
generic classes of metallic compounds (e.g., lead compounds, mercury
compounds, nickel compounds) as hazardous substances. Does this mean
that these metallic compounds now have a statutory RQ of one pound, or
would EPA's original determination exempt these releases from CERCLA
reporting requirements?

-------
                  SUPERFUND   (SF)
                            ANSWER: EPA's original determination of no reportable quantity remains
                            in effect for those generic compound categories designated as hazardous air
                            pollutants under §112 of the Clean Air Act Amendments (CAAA) of 1990
                            that were on the CERCLA hazardous substances list prior to the enactment
                            of the CAAA (EPA correspondence; August 23,1991). The generic classes of
                            compounds for which this applies are antimony, arsenic, beryllium,
                            cadmium, chromium, cyanides, lead, mercury, nickel, and selenium
                            compounds. Although releases of these generic classes of compounds do not
                            require CERCLA §103(a) notification, the owner or operator of a vessel or
                            facility can still be held liable for costs incurred in responding to their
                            release (50 FR 13461;  April 4, 1985).

                            Cobalt compounds, glycol ethers, manganese compounds, fine mineral fibers,
                            and polycyclic organic matter were also designated as hazardous air
                            pollutants in the CAAA. Since RQ determinations have not been
                            previously made for these compounds, they are automatically assigned the
                            one pound RQ pursuant to CERCLA §102(b).  EPA is currently evaluating the
                            physical, chemical, and toxicological properties of these compounds to
                            determine whether final RQs should be assigned to these categories.

"Heating Oil UST  Exclusion"

QUESTION: A company stores diesel fuel in an underground tank. The
diesel fuel is burned as a substitute for heating oil in an on-site furnace. The
definition of underground storage tank (UST) in 40 CFR §280.12 excludes any
tank used for storing heating oil for consumptive use on the premises where
stored. Does the underground tank storing diesel fuel meet this exclusion?
Would it meet the exclusion if the fuel is burned in a combustion engine?

ANSWER: An underground tank storing diesel fuel will meet this exclusion
if the diesel fuel will be substituted for heating oil; i.e., burned in a unit
designed to use heating oil. The exclusion to the definition of UST in
§280.12 has two parts: the definition of heating oil and the scope of
consumptive use.  A tank must meet both parts to be excluded.

Heating oil is defined in §280.12 as No.  1, No. 2, No. 4-light, No. 4-heavy,
No. 5-light, No. 5-heavy, and  No. 6 technical grades of fuel oil; residual
fuel oils (including Navy Special Fuel Oil and Bunker C); and fuel oil
substitutes such as kerosene and diesel fuel when used for heating purposes
(53 FR 37117; September 23, 1988). A tank storing  diesel fuel that will be
burned as an alternative to one of these eight types of heating oil in a unit
designed to burn heating oil is excluded from the definition of UST. If, on
the other hand, the diesel fuel is being used for some other purpose, such as
to power an internal combustion engine or an emergency generator, the tank
would not meet this exclusion. The question of whether tanks associated
with emergency power generators are excluded from the UST definition
under the heating oil exclusion is discussed on page 37118 of the September
23, 1988, Federal Register,  which specifically addresses such tanks.  The
language indicates that the use of heating oil itself is not limited to
heating, but may include other on-site uses, such as emergency generators.
This discussion does not incorporate or address the stipulation that USTs
containing fuels other than heating oil are only exempt if the fuel is burned
as a substitute for heating oil in units designed for heating oil. Therefore,
the language on page 37117 should be consulted for tanks containing other
fuels such as diesel fuel.

The second part of the exemption involves the meaning of consumptive use.
The exclusion applies to heating oil used at the same site where it is stored,
but not to heating oil that is stored prior to resale, marketing, or
distribution.  Consumptive  use of heating oil is not limited to  burning in a
heater, but instead is defined as any on-site use (53 FR 37117). Therefore,
the §280.12 exclusion from  the definition of UST applies to (1) tanks storing
one of the eight technical grades of fuel oil prior to any on-site use, and (2)
tanks storing fuel oil substitutes prior to use for on-site heating purposes
only. (October 1992 Monthly Hotline Report)

"Calculating the  Inventory Control  Standard"

QUESTION: According to 40 CFR Part 280, Subpart D, new underground
storage tank (UST) systems and existing systems of certain ages must be
fitted with release detection. One of the options to satisfy this requirement
combines tank-tightness testing at specified periods with monthly
inventory control, which consists of reconciling tank measurements against
delivery and dispensing quantities. Section 280.43(a) requires that this
method detect releases of "...at least 1.0 percent of flow-through plus 130
gallons on a monthly basis...." How is the 1.0 percent plus 130 gallons of
flow-through calculated?

ANSWER:  In order to determine whether a release has been detected, an
owner/operator must first determine the flow-through quantity; in other
words, the amount of regulated substance moving through the UST system
during any  given month. Flow-through may be calculated using either the
amount added to or the amount dispensed from the tank, as long as the same
measure is used consistently.

After establishing the flow-through quantity, the owner/operator next
computes 1.0 percent of that quantity, and  then adds 130 gallons.  Written
mathematically, the standard may be expressed as (0.01 x flow-through) +
130 gallons. The owner/operator then compares the result against the
cumulative  overage or shortage for the month to  determine if a leak has
been detected. For example, suppose 7,000 gallons of gasoline are dispensed
from an UST during September. Although 8,000 gallons were delivered
during September, the owner/operator always bases flow-through on the
quantity dispensed; therefore the flow-through quantity  is 7,000 gallons.
One percent of 7,000 gallons is 70 gallons, to which 130 gallons are added,
totaling 200 gallons ((0.01 x 7,000) + 130 = 200). The resulting 200 gallons
can then be compared against the cumulative overage or shortage for the
month to determine the presence of a leak. The margin for error allowed by
§280.43(a) helps reduce the frequency of false positive results from
temperature variations and measuring inaccuracies (a detailed discussion
can be found at 53 FR 37157; September 23,1988). More information on
inventory control is available in Detecting  Leaks: Successful Methods Step

"Temporary Closure of an  UST"

QUESTION: A company owns an underground storage tank that is
regulated under 40 CFR Part 280. Although regulated substances are not
being added to or dispensed from the tank (i.e., the tank is out of service),
the company plans to use the tank in the future.  With what operating
requirements must the owner/operator comply during the period the UST is
not in use?

ANSWER: When an UST is temporarily closed, an owner/operator must
continue operation and maintenance of corrosion protection, if a corrosion
protection system is present, in accordance with §280.31.  The
owner/operator must also demonstrate  financial  responsibility if its
compliance date in §280.91 has passed until the tank system is properly
closed per §280.109, and, as appropriate, follow release confirmation,
release notification, and corrective action procedures (§280.70(a)).   During
temporary closure, tanks may either continue to store regulated substances
or be emptied. If the tank stores regulated substances during temporary
closure, the owner/operator must also continue release detection. As
explained in the preamble to the September 23, 1988, Federal Register (p.
37182), however, release detection is not required during temporary closure
if the UST has been emptied in accordance with the procedures in
§280.70(a).  Of course,  those USTs that are not yet required to have release
detection according to  the schedule in §280.40(c) (note that the schedule
indicates that December 22, 1993, is the last release detection  deadline),
and those USTs that are deferred from release detection under §§280.10(c)
and (d) also are not required to have release detection when temporarily
closed.

An UST system that does not comply with the corrosion protection
standards in either §280.20 or §280.21 may remain in temporary closure for
a maximum of 12 months without prior approval from the implementing
agency. An extension may be granted by  the implementing agency.  Owners
and operators must complete a site assessment in accordance with §280.72
before applying  for an extension. If an extension is not granted, an UST
system must either meet the corrosion protection standards for new or
upgraded tanks after 12 months of temporary closure, or be permanently
closed (§280.70(c)). (December 1992 Monthly Hotline Report)

"States Authorized  for  the Underground  Storage Tank (UST)
Program"

QUESTION: Section 9004 of the Resource Conservation and Recovery Act
(RCRA) enables EPA to approve State underground storage tank (UST)
programs to operate in lieu of the Federal UST program. To qualify for final
approval, a State program must be "no less stringent" than the Federal
program and provide for adequate enforcement in accordance with
§§9004(a) and (b) of RCRA. To date, how many States have received final
approval?

ANSWER:  Currently, six States have  received final approval to operate
the UST program in lieu of EPA. The States are Georgia, Mississippi, New
Hampshire, New Mexico, North Dakota, and Vermont. Authorized States
have primary enforcement responsibility, although EPA retains the right
to conduct inspections under §9005 of RCRA and to take enforcement actions
under §9006 of RCRA. As of March 1992, EPA has issued tentative
determinations to grant approval to two other States, Maine and
Maryland, to operate the Federal UST  program. A tentative
determination, like a proposed rulemaking, is followed by a comment
period and requires a subsequent action granting or denying approval.
Maine and Maryland are expected to receive approval during 1992.

States without UST program approval may have a  Memorandum of
Agreement with their EPA Regional Office which  allows them to
implement specific parts of the UST regulations on behalf of the Region.
Questions regarding the contents of any agreement should be addressed to
the appropriate State agency.  (March 1992 Monthly Hotline Report)

QUESTION: A Local Emergency Planning Committee (LEPC) must be
representative of different groups and organizations, as described in §301(c)
of the Superfund Amendments and Reauthorization Act (SARA) Title III.*
It states that, at a minimum, an LEPC must include "...representatives from
each of the following groups or organizations: elected State and local
officials; law enforcement, civil defense, firefighting,  first aid, health,
local environmental, hospital, and transportation personnel; broadcast and
print media; community groups; and owners and operators of facilities
subject to the requirements of this subtitle."  Does an LEPC have to consist of
one individual representative from each group and organization, or can one
member of an LEPC represent more than one group or organization listed?

ANSWER: In order for an LEPC to properly carry out its duties, such as
developing and distributing an emergency plan and responding to public
comment, it must consist of representatives from different groups and
organizations as described in §301 (c). One member of an LEPC can be the
representative for more than one group or organization, but the LEPC must
include representatives from all the groups and organizations listed in the
statute. For example, a member of the LEPC could be both the community
group representative and the hospital representative, assuming that person
is involved in both organizations.  (January 1992 Monthly Hotline Report)

"Pesticides Toward  TPQ Under SARA Section  302"

QUESTION: SARA §302 requires owners and operators of facilities that
have extremely hazardous substances (EHS's) present above the threshold
planning quantity (TPQ) to participate in emergency planning (40 CFR
§355.30). If a facility has a pesticide sprayed on its grounds without first
being stored at the facility, must the amount of EHS present in the
pesticide that has been applied be counted towards the TPQ?

ANSWER:  Under SARA §302, an owner or operator must identify any
EHS's that are present at the facility and, for each EHS, determine the
amount present.  If the amount present equals or exceeds the EHS's TPQ,
then the facility is subject to emergency  planning requirements.  In this
specific example, the facility would not  count the amount of EHS present in
the soil toward the EHS's TPQ because it is not present in a contained
structure. The definition of facility (40  CFR §355.20) includes all buildings,
equipment, structures, and other stationary items that are located on a
single site or on contiguous or adjacent sites and which are owned or
operated by the same person. This includes man-made structures in which
chemicals are purposefully placed or removed through human means such
that it functions as a containment structure for human use.  Once it is
applied, the residual pesticide does not have to be applied toward the
threshold determination. It can be considered no longer "present at the
facility." This does not, however, exempt the owner or operator from
emergency planning requirements for EHS's present above their TPQ at the
facility, such as any EHS in a pesticide  that is brought on-site prior to
application, stored, or present anywhere  else at the facility. (February

"Consumer Product Exemption  Applied to §§311 and 312"

QUESTION: Pennsylvania restricts the use of a product that is packaged
for distribution and use by the general public by requiring users within the
State to obtain a license. This product requires a material safety data
sheet under OSHA, and thus may be subject to the reporting requirements of
the Emergency Planning and Community Right-to-Know Act, EPCRA §§311
and 312. Does this product meet the consumer product exemption under the
definition of hazardous chemical, which is "...any substance to the extent it
is used for personal, family, or household purposes, or is present in the same
form and concentration as a product packaged for distribution and use by the
general public" (40 CFR §370.2)?

ANSWER: Any substance that is in the same form and concentration as a
product packaged for distribution and use by the general public is exempt
from the definition of hazardous chemical and is not reportable under
EPCRA §§311 and 312. This exception to the definition of hazardous
chemical under EPCRA has been referred to as the "consumer product
exemption." If a license is required for use of a product, it may not be
considered a consumer product. In this case, the determining factor is
accessibility of the product by the general public. If any private citizen can
obtain a license for use of the product, then it is considered a consumer
product. If some private citizens cannot obtain the license, then the use of
the product is limited to facilities that can  obtain the license; thus the
product does not meet the consumer product exemption.  If the restricted
product is present at a facility above the applicable reporting threshold,
then it is reportable under EPCRA §§311 and 312.  Reporting on this product
may vary from State to State depending on the requirements and
limitations in obtaining a license for use. (May 1992 Monthly Hotline

"Activity  Indices and Production Ratios"

QUESTION:  For the purposes of reporting in Section 8.9 of the Form R (40
CFR §372.85), a facility must provide a ratio of the reporting year
production to prior year production, or provide an "activity index" based on
a variable  other than production that is the primary influence on the
quantity of the reported toxic chemical recycled, used for energy recovery,
treated, or disposed of. How should one-time or batch processors determine
an activity index or production ratio for reporting in Section 8.9 of the
Form R?

ANSWER: A one-time processor in its first year of using a toxic chemical
should report "NA" in Section 8.9 of the Form R. If a one-time processor uses
a toxic chemical on a yearly basis but in different products, applications,
and quantities, then a production ratio based on production or application
involving the toxic chemical should be calculated as follows: (production
involving the toxic chemical in the  current year •*• production involving the
toxic chemical in the prior year).

Batch processors should calculate a ratio based on campaigns involving the
toxic chemical from year to year as follows:  (campaign production in the
current year + campaign production in the prior year). (August 1992

"Article  Disposal  After  Use"

QUESTION:  A facility subject to §313 of the Emergency Planning and
Community Right-to-Know Act assembles circuit boards and other
"articles" to create a larger finished product by soldering them together.
During assembly, the individual circuit boards retain their article status
and are therefore excluded  from §313 reporting under 40 CFR §372.38(b).  If
the final product does not meet manufacturing specifications and is disposed
of, do  the  individual pieces retain  their article status?  Is disposal of the
finished product considered a release for purposes of completing the Form
R?

ANSWER: The individual circuit board  pieces retain their article status
as long as the item being disposed  of is still recognizable as an article. As
stated in the final rule on §313 reporting (53 FR 4507; February 16,1988),
"toxic chemicals in an item that qualifies as an article are not subject to
reporting even if the facility disposes of the article after use." The
disposal of the final product in this scenario, therefore, would not be
considered a release.  (September 1992 Monthly Hotline Report)

"Catalyst as an  Article"

QUESTION: A facility uses a catalyst containing a listed toxic chemical in
a fixed bed reactor. The catalyst is in the form of cylindrical or trilobed
extrudates (pellets) in specific sizes. It is used to promote a chemical
reaction and is not physically altered during use.  The spent catalyst is sent
off-site to be reclaimed. Can the catalyst be exempted as an article under
§313 of the Emergency Planning and Community Right-to-Know Act?

ANSWER:  No. The catalyst is manufactured to a specific shape or design
and has end use functions dependent upon that shape;  however, EPA
believes that releases occuring during use and transfer operations would
prevent it from meeting the article definition. Such catalysts usually
contain dust-size material that is not the same size and shape of the
pellets.  The likely releases would be dust emissions and spills that occur
during charging and removing the catalyst from the reactor. Such
operations are part of the normal conditions of processing and use that must
be considered under the article definition.  The spent catalyst sent off-site
for recycling does not itself constitute a release that invalidates the article
exemption, as long as all of the toxic chemical is recycled.  The facility
should also consider whether any on-site regeneration of the catalyst
results in the toxic chemical being released in wastestreams. (March 1992

"Estimating  Releases for  §313"

QUESTION: For purposes of reporting on the Form R under §313 (40 CFR

and other potential emission points and, in turn, uses these measurements to
estimate releases.  Should the facility report the basis of the estimate as
"M" (monitoring), or "E" (emission factors) in §5.1 of the Form R?

ANSWER: The facility should enter "M" (monitoring) in §5.l.B.  The Form
R instructions state that "M" is used when "...the estimate is based on
monitoring data or measurements for the toxic chemical as released to the
environment and/or off-site facility." The basis of the estimate should be

"Laboratory Activities Exemption  Under EPCRA §313"

QUESTION:  A manufacturing facility operates several on-site
laboratories and shops (e.g., machine shops, glass blowing shops) that
support the laboratories' activities.  Assuming the activities in the
laboratories are exempt under 40 CFR §372.38(d), are the toxic chemicals
used in the shops also exempt from threshold and release determinations?
If the shops also support some nonexempt laboratory activities, would they
be required to account for the fraction of chemicals used for nonexempt
purposes?

ANSWER: In either case the toxic chemicals used in the shops would not be
exempt from threshold and release determinations. The fact that the
shops support exempt laboratory activities does not exclude the toxic
chemicals  used in the shops from threshold and release determination.  The
laboratory activities exemption in §372.38(d) applies to toxic chemicals
that are manufactured, processed, or otherwise used for certain purposes
such as research or quality control in a laboratory under the supervision of a
technically qualified individual. This exemption  does not exempt the
facilities themselves, it only exempts those toxic chemicals that  are
manufactured, processed, or otherwise used in certain laboratory activities
from threshold and release determinations required under EPCRA §313.
Specifically, §372.38(d)(3) states that the exemption does not apply to
"activities  conducted outside the laboratory." (October 1992 Monthly

Should the 2,000 pounds be counted toward determination of the
manufacturing threshold under §313 of the Emergency Planning and

ANSWER:  The 2,000 pounds are exempt from the threshold determination
for manufacturing under the laboratory use exemption (40 CFR §372.38(d))
because the toxic chemical was manufactured in a laboratory under the
supervision of a technically qualified individual.  The facility will count

"Light  Bulb Stem Disposal"

QUESTION: A facility subject to §313 of the Emergency Planning and

are disposed of. There is a lead "button" in each light bulb stem which is
disposed of.  Is this button considered an article and therefore exempt from
threshold and release calculations under 40 CFR §372.38(b)?

ANSWER: No, the lead buttons from crushed light bulbs would not be
considered articles and the lead would not be exempt from threshold and
release calculations. Disposal of a toxic chemical, however, is not  a
covered activity (i.e., manufactured, processed, or otherwise used).
Therefore the lead in these buttons would not  be counted toward any
threshold. The facility would only be required to report the release of lead
buttons if a threshold for lead was exceeded by a covered activity
elsewhere at the facility. (September 1992 Monthly Hotline Report)

being smelted when determining the maximum amount on-site?

ANSWER:  When determining the maximum amount on-site for Part II,
Section 4 of the Form R, the facility must aggregate all nonexempt forms of
the toxic chemical. Toxic chemicals present in waste as well as in scrap
metal are not exempt from reporting on the Form R. The amount of the toxic

reacts with other  chemicals in the processing stream. If, on the other hand,
phosphoric acid exiting in the wastestream reacts with other chemicals
present in the wastestream to a pH above 6, it would be reported as a

QUESTION: A facility covered under §313 of the Emergency Planning and

During production the facility uses adhesives that contain solvents such as

Would the facility count the amount of solvent remaining in the shoes
toward the 25,000-pound processing threshold?

ANSWER: No. The amount of solvent used in the adhesive would count
toward the 10,000-pound otherwise use threshold. Since the retention of
the solvents in the adhesives used to produce the shoes is unintentional, it
would not be considered processed.  Thus, the facility would file a Form R if
it meets a 10,000-pound otherwise use threshold for the acetone or toluene
in the adhesive. (January 1992 Monthly Hotline Report)

"Reclamation  as  Processing Under  EPCRA §313"

QUESTION: A reclamation facility receives waste solvents containing an
EPCRA §313 toxic chemical from a separate facility that generated the
wastes (the generating facility).  The reclamation facility reclaims the
toxic chemical and returns it, as a product, to the generating facility.  For
the purpose of EPCRA §313 threshold determinations, is the reclamation
facility processing the toxic chemical?

ANSWER: The term "process" is defined at 40 CFR §372.3 as "...the
preparation of a toxic chemical, after its manufacture, for distribution in
commerce."  The final rule implementing the EPCRA §313  regulations (53
FR 4506; February 16, 1988) further clarifies this definition by stating that
"[t]he process definition focuses on the incorporation of a chemical into a
product that is distributed in commerce."

By reclaiming the toxic chemical and returning it to the generator, the
reclamation facility  has prepared the chemical for distribution in
commerce by incorporation of the chemical into a product.  Therefore, the
reclamation facility  is  processing the toxic chemical in the waste solvent it
receives. Assuming the reclamation facility is a manufacturing facility
with 10 or more full-time employees, it is required to report under EPCRA
§313 for the toxic chemical if it exceeds an activity threshold (e.g.,
processing more than 25,000 pounds) during the course of a calendar year.

"Recycle/Reuse  Activity  Under  §313"

QUESTION: Refractory bricks containing 12,000 pounds of lead are

Community Right-to-Know Act?  Also, are releases of lead from the bricks
during reporting year 1991 subject to release reporting on the Form R (40 CFR
Part 372) if no new bricks are added during the calendar year?

ANSWER: The lead contained in the bricks is considered "otherwise used"
since it is not incorporated into the final product.  The facility would count
the amount of lead in the bricks that are added to the reaction vessel only
for the year in which the bricks are installed.  In answer to the second
question, if the 10,000-pound threshold is exceeded, then all releases of
lead would be reported. Neither the lead contained in the refractory bricks
in the inventory (i.e., not yet installed), nor in-place lead contained in
bricks (i.e., installed in a previous year) are to be included in threshold
determination for the reporting year in question.  If no bricks are installed

"Release  Reporting  of Process-Generated  Dusts"

QUESTION:  A facility subject to §313 of the Emergency Planning and
Community Right-to-Know Act processes items containing listed §313 toxic
chemicals.  During processing, dusts are released to air withing the facility
and some of this dust settles out within the facility (on rafters, equipment,
floors and in adjacent rooms). If a processing threshold is met, how would
the facility report the releases of the toxic chemicals present in the dust on
the Form R in section 5?

ANSWER:  The facility must account for the amount of the toxic chemical
released to various environmental media. Reporting of releases is based on
the entire calendar year.  If during the year an amount in dusts that settle
out are collected and disposed of, then this would be reported as an amount
disposed of on-site or off-site in the appropriate section of Form R (e.g., if
the dusts are sent off-site for disposal they  would be reported in Part II,
Section 6.2). Any amount of toxic chemical in dusts that remain airborne
would be reported as a fugitive release.  Amounts released that settle out on
facility structures or equipment that are not collected and  disposed of
should be reported in Section 5.5.4 of Form  R as a release to land on-site.

"Remedial  Action for  Pollution  Prevention"

QUESTION: Is dredging a lagoon (or surface impoundment) containing a
§313 toxic chemical once every five years (routine procedure) considered a
remedial action under the Pollution Prevention Act? If so, how should
releases from the dredging be reported in §8.8 of the Form R (40 CFR Part
372)?

ANSWER: Because the dredging of the lagoon (or surface impoundment)
occurs routinely every five years, it is not considered a remedial action
under the Pollution Prevention Act, and accordingly, releases from the
dredging should not be reported as releases from remedial actions.  Instead,
releases resulting from dredging would be reported in §5 or §6 of the Form R,
depending on the ultimate disposition of the chemical.  (June 1992 Monthly

"Reporting  on  Polymeric Lead Compounds"

QUESTION: A polymeric lead compound is processed at a facility in excess
of the 25,000-pound threshold during the reporting year. Is a polymer that
contains lead as a part of its infrastructure considered to be a lead compound
under §313 of the Emergency Planning and Community Right-to-Know Act?

ANSWER: The polymer would be considered to be a lead compound.
According to Directive 4 on compounds and mixtures in the Toxic Chemical
Release Inventory Reporting Package for 1990, a compound is any
combination of two or more chemicals where the result is (in whole or in
part) a product of a chemical reaction. In the formation of a compound, the
reactant chemicals lose their individual chemical identities.  Polymers
formed as nonreversible reaction products are an example of a compound.
Since this polymer is a compound, under §313 (40 CFR §372.22(h)), a
polymeric lead compound processed at a facility would count toward the
threshold determination for lead compounds. (August 1992 Monthly
Hotline Report)

"Routine Maintenance Exemption Under  EPCRA §313"

QUESTION: An EPCRA §313 toxic chemical is used to clean a process-
related tower at a manufacturing facility.  Is this use of the chemical
exempt from threshold  and release calculations under the routine janitorial
and facility grounds maintenance exemption of 40 CFR §372.38(c)(2)?

ANSWER:  Materials used to maintain process-related equipment at a
facility (e.g.,  cleaners and lubricants) are not exempt under §372.38(c)(2).
Because the tower is process-related, the exemption does not  apply.  This
exemption only applies to the use of products that are similar in type or
concentration to consumer products and are specifically used for routine
janitorial or facility grounds maintenance.  (October 1992 Monthly Hotline
Report)

Structural Component Exemption Under  EPCRA §313

QUESTION: A manufacturing company paints on-site buildings as part of
its routine facility maintenance.  The solvent in the paint is an EPCRA §313
toxic chemical. The paintbrushes used to paint the buildings are cleaned
with a solvent that is also an EPCRA §313 toxic chemical. Is the solvent
used to clean the brushes subject to threshold and relase calculations under
§313?

ANSWER: The structural component exemption set out at 40 CFR
§372.38(c)(l) applies to the solvent in the paint used to paint the facility.
It also applies to the solvent used to clean the paintbrushes since this is
part of the painting process.  Likewise, any paint and cleaning solvent
residues would not be subject to threshold or release calculations.  (October

QUESTION: Chemicals are routinely added to or deleted from the existing
EPCRA §313 list of toxic chemicals.  When must I begin providing a
supplier notification (40 CFR §372.45) for a newly added chemical? What
about chemicals that were covered for calendar years 1987 and 1988?

ANSWER:  For a chemical added on or after January 1 and before December
1 of any calendar year, supplier notifications are to be provided with the
first shipment of the chemical in the following calendar year and every
year thereafter.  For example, a chemical added on April 1,1991, requires a
notification beginning with the first shipment of the chemical in the 1992
calendar year.

For a chemical added on or after December 1 of any calendar year and
before January 1 of  the next calendar year, supplier notifications are to be

"TDI  Thresholds and  Releases"

QUESTION:  A facility has three separate process streams: one containing
2,4-toluene diisocyanate (TDI), with CAS number 584-84-9; the second
containing 2,6-TDI, with CAS number 91-08-7; and the third containing TDI
(mixed isomers), with CAS number 26471-62-5. In the past, the list of §313
toxic chemicals included 2,4-TDI and 2,6-TDI. On December 1,1989, TDI
(mixed isomers) was added to the list. How should a facility calculate the
thresholds and releases for each isomer and for the mixture of TDI? If the
facility knows the composition of the mixture, should it  total the amount of
the pure 2,4-TDI and 2,6-TDI with the amount in the mixture to determine
if the thresholds for the individual isomers have been met?

ANSWER:  Because the §313 list of toxic chemicals includes listings for
pure 2,4-TDI, pure 2,6-TDI, and  TDI  (mixed isomers), the facility should
calculate the thresholds separately for each stream. The components of
the mixture should not be applied to the thresholds of pure isomers.  If the
individual thresholds are not met, no reporting is necessary.  If the
individual thresholds are exceeded, the facility may file a single report
for TDI (mixed isomers) and include the total releases and transfers of all
three process streams, or file three separate reports (40 CFR Part 372).

Concentration; de minimis
"Threshold  Determination  Based  on the  Range  of
Concentration  Given  on the MSDS"

QUESTION: A facility regulated under §313 of the Emergency Planning
and Community Right-to-Know Act (EPCRA) uses a chemical mixture that
contains a listed §313 toxic chemical. The concentration of the toxic
chemical is given as a range on the material safety data sheet (MSDS). If
the maximum and minimum concentrations are above and below the de
minimis concentration level, how can the facility determine quantities for
§313 compliance (40 CFR Part 372)?

ANSWER: The amount of the chemical in the mixture that is above the de
minimis level, and therefore counts toward the threshold, can be assumed
to be proportional to the  ratio of the amount above de minimis concentration
to the amount of the total concentration range. The concentration of the
chemical in the mixture that is not exempt is the average of the de minimis
level and the maximum concentration.

For example, assume that a facility manufactures 10 million pounds of a
mixture containing 0.25-1.20 percent of a toxic chemical that is subject to a 1
percent de minimis exemption. The quantity of that mixture subject to
reporting is:

10,000,000 Ibx (1.20-1.00) = 2.105.263 Ib nonexempt mixture
             (1.20-0.25)

This 2,105,263 pounds of nonexempt mixture is multiplied by the average
concentration above the de minimis, which is 1.1 percent, or
                                                       1.20+1.00
                                                            2


                                                  2,105,263 x 0.011 = 23,158 Ib

                            In this example, the amount of chemical that counts toward a threshold is
                            23,158 pounds. (July 1992 Monthly Hotline Report)

"Threshold  Determination  Under  Section 313"

QUESTION:  A facility covered under §313 of the Emergency Planning and
Community Right-to-Know Act manufactures and repairs airplanes. Prior
to beginning any repair work, any fuel remaining in the airplane's fuel
tanks is emptied by service personnel at the  facility. After the repairs are
completed, the airplane is refueled with fuel removed from the airplane's
fuel tanks and/or new fuel. Should the owner/operator of the
manufacturing and repair facility consider the toxic chemicals present in
the fuel when making §313 threshold and release calculations?

ANSWER: Yes.  For purposes of §313 threshold and release calculations,
the toxic chemicals present in the fuel would be considered to be processed
because they are being further distributed in commerce. Thus, the toxic
chemicals present in the fuel are subject to the 25,000 Ib processing
threshold. (February  1992 Monthly Hotline Report)

"TRI  Facility  Location"

QUESTION: A facility regulated under §313 of the Emergency Planning

When the physical  location is  listed as  the mailing address, the mail is
returned to the sender by the Post Office.  For reporting on the Form R,
Section 3.1, what should the facility list as its mailing address?

ANSWER: The reporting year 1991 Form R contains a separate field for
mailing addresses.  The facility should enter  its mailing address in this
field if it is different  from the facility's  physical address. The facility
must always enter its physical  address in the appropriate section of the
Form R (40 CFR Part 372).  (March 1992 Monthly Hotline Report)

"Wastepile  Releases Under  EPCRA  §313"

QUESTION: A facility continually places material containing a toxic
chemical on the land in a pile during a calendar year. The facility is
intending to have the pile hauled off-site during the next calendar year.
Must the facility report the toxic chemical in the pile as released to land
for the calendar year in which it places the material in the pile?

ANSWER:  (In the following answer, it is assumed that the material is
being transferred off-site for the purpose of disposal, treatment, energy
recovery, or recycling.)

Material that is added to a pile during a calendar year does not have to be
reported, for that calendar year, as a release to land if the  pile was used
only for temporary storage. EPA will consider that the pile was used for
temporary storage if the facility routinely made off-site transfers of
material from the pile during that calendar year.  The  facility should be
able  to demonstrate that they conducted such routine transfers.

If a facility did not make such routine transfers during a calendar year in
which  material was added  to the pile, EPA will consider  that the pile was
for disposal, and the quantity of toxic chemical placed on the pile during
that  calendar year and present at the end of that year must be reported as a
release to land, regardless of the facility's intention to  transfer the
material off-site in an ensuing year. If, in an ensuring year, such material is
transferred off-site, the movement would be counted as a transfer off-site
even though this entails double counting.  (November 1992 Monthly

"Timing  of  Surface Impoundment Retrofitting  Under the Land
Disposal  Restrictions"

SUMMARY: This proposal clarifies the deadline by which surface
impoundments receiving wastes that are newly identified or listed as
hazardous must be brought into compliance with the minimum
technological requirements (MTR) established in RCRA §3004(o)(l)(A).
The proposal would give all surface impoundments up to four years from the
date of compliance to comply with the MTR.

"Proposed Hazardous  Waste  Identification Rule"

SUMMARY:  This rule proposed amendments to RCRA regulations for
hazardous waste identification. The Agency presented two options.  The
first would establish Concentration-Based Exclusion Criteria (CBEC) or
exemption levels for constituents found in certain wastes. The second option
would expand the number of hazardous constituents listed under the
toxicity characteristic and is referred to as the Expanded Characteristic
Option, or ECHO. Comments will be accepted until July 29,1992. This
proposed rule was withdrawn on October 30,1992 (57 FR 49280).

"Land  Disposal Restrictions 'No  Migration' Variances"

SUMMARY: This rule proposes EPA's interpretation of the "no migration"
variance to the Congressionally mandated restrictions on land disposal of
hazardous waste. EPA also proposed new requirements for petitioning EPA
and demonstrating that there will be "no migration" from a land disposal
unit. Comments on this proposed rule must be received on or before
September 25,1992.

SUMMARY: In response to the January 9,1992, proposed rule on LDR for
newly listed wastes and hazardous debris ( 57 FR 958), EPA  received
numerous comments regarding the availability of treatment capacity for
hazardous debris.  Most of the commenters indicated that it will be
extremely difficult if not impossible to meet the proposed standards for
hazardous debris, or the existing standards by May 8, 1992, when the
national capacity variance for  most debris expires.  Under 40 CFR §268.5,
EPA therefore approved a generic, one-year extension of the LDR effective
date applicable to all persons managing hazardous debris. This rule
became effective on May 8, 1992.

            PART  3:   INDICES
This section provides three indices to help you select and access the questions and answers
in Part 1 and the Federal Register summaries in Part 2. The first index references the
questions and FR summaries by subject. The questions and FR summaries that address that
topic are listed below each subject. For example, to find questions dealing with light bulbs,
you would look in the subject index for the word "light bulbs" and find two questions
referenced under that subject: "Fluorescent Light Bulbs as Debris" and "Light Bulb Stem
Disposal." The reference provides the page number for full text and is coded with a capital
letter to indicate the relevant program (i.e., R=RCRA, S=Supcrfund, U=UST, and
E=EPCRA).

The second index organizes the questions and FR summaries by regulatory citation,
beginning with 40 CFR Part 261. This index is useful for identifying questions affecting
specific portions of the regulations.  For example, under the heading "40 CFR Part 281 -
Approval  of State Underground Storage Tank Programs" is a question entitled "States
Authorized for the Underground Storage Tank (UST) Program" and a Federal Register
notice from January 3, 1992, regarding final approval of the UST program for the state of
Vermont.

Similarly,  the third index organizes the questions by statutory citation.  For example, the
question entitled "Article Disposal After Use" is referenced under "Section 313 - Toxic
Chemical  Release Forms."

These three indices allow the reader flexibility in  searching  for a specific topic or  getting
an overview of the scope of the questions by selecting the approach most useful to the
reader.
                                                                             75
