            INTRODUCTION
The Resource Conservation and Recovery Act (RCRA)/Underground Storage Tanks (UST),
Superfund, and Emergency Planning and Community Right-to-Know Act (EPCRA) Hotline
was established to respond to inquiries from the regulated community and the public
concerning waste management, disposal, and emergency planning and response regulations.
In addition, the Hotline serves as point of contact for the Radiation Sites Cleanup Program
and the risk management program under the Clean Air Act §112(r). The Hotline also
functions 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 1993. 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 understand 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 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
Monthly Hotline Reports for the period of January to December 1993.  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 1993 the Hotline responded to
almost 200,000 questions regarding EPA regulations, programs, guidance documents, and
other related matters.  Of the 198,572 questions received, over two  thirds of the
questions concerned regulatory information and nearly one quarter were requests for EPA
documents.  Six 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 questions and answers have undergone technical 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 Monthly Hotline Report is cited at the end of the
entry. The questions in this section are grouped by EPA program area, then further grouped
under broad, general regulatory areas and titles. To pinpoint a subject or topic more specific
than the general regulatory area headings, please use the Indices in Part 3.

"Soil Case-by-Case  Extension"

QUESTION: EPA established a generic case-by-case extension of the
land disposal restrictions effective date for soils contaminated with
Third Third wastes that have treatment standards based on
incineration, vitrification, or mercury retorting in the October 20,1992,
Federal Register (57 FR 47772).  This extension allows soils
contaminated with these wastes to be land disposed without meeting
Part 268, Subpart D treatment standards provided that the generator or
owner/operator complies with certain recordkeeping requirements (57
FR 47775-47776). Treatment standards for both arsenic (D004) and lead
(D008) were promulgated in the Third Third final rule.  Since the
treatment standard for D004 is based on vitrification (55 FR 22556; June
1, 1992), soil that exhibits the toxicity characteristic (and the
characteristic of EP toxicity)  for arsenic qualifies for the case-by-case
extension.  The treatment standard for D008 (lead) is based on
stabilization (55 FR 22565); soil that  exhibits the toxicity
characteristic (and EP) for D008  only does not qualify for the extension.
Does soil that exhibits the TC (and EP) for both lead and arsenic
qualify for the generic case-by-case extension?

ANSWER:  Soil that exhibits the TC (and EP) for both lead and arsenic
qualifies for the generic soil case-by-case extension, and need not be treated
to meet either the lead (D008) or the arsenic (D004) treatment standard
until May 8, 1993. When soil is contaminated with two or more Third Third
wastes, the soil qualifies for the October 20, 1992, generic case-by-case
extension as long as at least one of the Third Third wastes with which it is
contaminated has a treatment standard based on incineration, vitrification,
or mercury retorting, or if it is contaminated with radioactive mixed waste.
Soil that is contaminated with an eligible Third Third waste and a  Second
Third waste also qualifies for the case-by-case extension, since the
maximum period allowable for capacity extensions under RCRA §3004(h) is
four years, and four years have not yet passed since the treatment standards
for Second Third wastes were promulgated. If soil is contaminated with a
Third Third waste that is eligible for the  extension and a solvent, dioxin,
California list, or First Third waste, however, the soil must meet the
treatment standard for the non-Third Third waste before it can be land
disposed. Any other interpretation would result in EPA extending the date
of a prohibition beyond  the dates established by Congress, and therefore
beyond EPA's legal authority (see the June 1,1990, Federal Register:

                      RESOURCE CONSERVATION  AND  RECOVERY  ACT
                      (RCRA)
                            "Soil Case-by-Case  Extension"  (cont'd)

                            55 FR 22650).  For example, if soil is contaminated with D004 and an F-
                            listed spent solvent waste (e.g., FOOD, the soil must be treated to meet
                            the F001 treatment standard prior to disposal.

                            Note that EPA promulgated treatment standards for four newly listed
                            F002 and F005 solvent constituents in the Third Third final rule (1,1,2-
                            trichloroethane; benzene; 2-ethoxyethanol; and 2-nitropropane).
                            Unlike all other F001-F005  spent solvent wastes which had treatment
                            standards promulgated in the November 7,1986, Federal Register
                            (51 FR 40572), these newly listed F002 and F005  solvents are considered
                            Third Third wastes. F002-  and  F005-contaminated soil that contains
                            one or more of the four newly listed solvent constituents and no other F-
                            listed solvent constituents is eligible for  the soil case-by-case extension,
                            since the nonwastewater treatment standards for these F002 and F005
                            constituents are based on incineration (see 55 FR 22577-22578).

"Effective Date  Delayed  for Certain MSWLFs"

QUESTION:  EPA promulgated criteria for municipal solid waste landfills
in 1991 to provide minimum national performance standards and to reduce
the risk of harmful effects of solid waste on human health and the
environment (56 FR 50978; October 9,1991). Codified at 40 CFR Part 258,
the municipal solid waste landfill (MSWLF) regulations require landfill
owners and operators to comply with specific location restrictions,
operating criteria, design criteria, groundwater monitoring and corrective
action, closure and post-closure care, and financial assurance criteria. These
regulations establish a schedule of compliance for owners and operators
that spans several  years.  EPA recently issued a rule changing the effective
dates of the federal MSWLF criteria for certain landfills (58 FR 51536;
October 1,1993). What specific changes to the MSWLF criteria were
finalized?

ANSWER: EPA recognized that a variety of circumstances made
compliance with the MSWLF criteria's October 9, 1993, deadline difficult
for certain MSWLF owners and operators. Landfills in smaller communities
have encountered  the most difficulty meeting the deadline, despite good-
faith efforts, because financial conditions, legal challenges, and geography

                     "Effective  Date  Delayed  for  Certain MSWLFs" (cont'd)

                     have created significant obstacles to compliance. To provide regulatory
                     relief for owners and operators, EPA has changed some of the effective
                     dates of the MSWLF criteria. Specifically, limited extensions have been
                     provided for these existing smaller landfills and for landfills accepting
                     waste resulting from the flooding in the Midwest. Additional extensions
                     also have been granted to all landfills required to comply with the
                     financial assurance and final cover regulations.

                     The Part 258 regulations required existing landfills to comply with most
                     requirements by October 9,1993. EPA has extended the compliance date for
                     eligible small landfills to April 9, 1994. Eligible landfills are those that
                     accept less than 100 tons of solid waste per day; are located in a state that
                     has submitted an application to EPA for approval of its permit program by
                     October 9,1993, or are located on Indian lands or Indian country; and are not
                     on CERCLA's National Priorities List.

                     In the October 1,1993, final rule, EPA also provided some regulatory relief
                     for MSWLFs accepting waste resulting from the flooding in the Midwest.
                     The effective date may be extended up to April 9,1994, for existing
                     landfills regardless of size, if a landfill owner or operator's state
                     determines that an extension is needed to manage flood-related waste from
                     federally designated disaster areas. These states also may allow their
                     landfills up to six more months (beyond April 9,1994) to comply with the
                     federal regulations. Federal disaster areas covered by this extension are in
                     the states of Illinois, Iowa, Kansas, Minnesota, Missouri, Nebraska, North
                     Dakota, South Dakota, and Wisconsin.

                     For all landfills, the requirement to obtain financial assurance has been
                     delayed from April 9,1994, to April 9,1995. EPA believes that the
                     extension will allow adequate time to promulgate a financial test for local
                     governments and an additional mechanism for corporations. EPA also has
                     extended the time allowed to install  a final cover for those landfills that
                     cease receiving waste before the effective  date of the regulations.  A final
                     cover that meets the federal criteria in 40 CFR §§258.60(a) or (b) must be
                     installed in most cases by October 9,1994.

                     In response to a court decision, the exemption from groundwater monitoring
                     requirements for very small, arid, and remote landfills has been removed.
                     The effective date for landfills  previously qualifying for the exemption is
                     October 9, 1995. EPA is still committed to investigating alternative
                     groundwater monitoring requirements for this group and will continue to
                     examine this issue.

                            dates. EPA strongly encourages owners and operators of MSWLFs to consult
                            with  their state or tribal government as they may have earlier effective
                            dates or other requirements. (October 1993 Hotline Monthly Report)

"Procurement  Requirements Applicable to Government
Agencies"

QUESTION: One of the primary objectives of the Resource Conservation
and Recovery Act (RCRA) is to conserve valuable material and energy
resources (§1003(a)). Because the collective purchasing power of federal,
state, and local governments has significant potential to expand markets
for products made with recovered materials, RCRA §6002 requires
government procuring agencies, when purchasing EPA-designated items, to
select items with the highest amount of recovered  material content
practicable. All  federal agencies must  review and revise all of their
specifications for products to eliminate language which discriminates
against the use of recovered materials.  In addition, each procuring agency
subject to §6002 must establish an affirmative procurement program for each
item designated by EPA. How does a government agency determine
whether or not it must comply with the requirements of §6002?

ANSWER: A government agency should answer the following three
questions to determine if it is subject to the requirements of §6002. First,
does the government agency meet the definition of a procuring agency? The
definition of procuring agency includes federal agencies, as well as state
and local government agencies using federal funds, and their contractors.
Specifically, RCRA §1004(17) defines a  procuring agency as "...any federal
agency, or any state agency or agency of a political subdivision of a state
which is using appropriated federal funds for such procurement, or any
person contracting with any such agency with respect to work performed
under such contract." For purposes of this definition, the use of
appropriated federal funds includes the use of federal funds commingled
with state or local funds.

The second question is, does the government agency purchase a product
designated in an EPA guideline? The affirmative procurement program
requirements in  §6002 are limited to products specifically designated by
EPA procurement guidelines. Procuring agencies, however, are encouraged
to establish affirmative procurement programs for other  available items
made with recycled materials. In addition to designating which items are
covered by §6002, EPA procurement guidelines provide recommendations for
government agencies to carry out the responsibilities of §6002. To date, EPA
has issued five procurement guidelines.  The guidelines are found in 40 CFR

-------
        RESOURCE  CONSERVATION  AND  RECOVERY  ACT
                                                               (RCRA)
                            "Procurement Requirements  Applicable  to  Government
                            Agencies"  (cont'd)

                            Parts 248,249, 250,252 and 253, and provide recommendations for the
                            procurement of building insulation, cement and concrete containing fly ash,
                            paper and paper products, re-refined lubricating oil, and retread tires,
                            respectively.

                            Finally, does the government agency purchase $10,000 or more worth of a
                            product designated in an EPA guideline during the course of the current
                            fiscal year or did the agency purchase $10,000 or more worth of a
                            designated item or functionally equivalent items during the preceding
                            fiscal year? Each guideline specifies how "functional equivalence" should
                            be interpreted to determine whether the government agency has reached
                            the $10,000 threshold. If the answer to all three of the above questions is
                            yes, the agency must comply with the requirements of §6002. In other
                            words, government agencies that meet the definition of a procuring agency

"Closure Timetable  Following Termination of  Interim  Status"

QUESTION: According to 40 CFR §270.73(g), interim status terminates on
November 8, 1992, for any facility, other than a land disposal or
incinerator facility, that achieved interim status prior to November 8,
1984, unless the facility's owner or operator submitted a RCRA Part B
permit application by November 8, 1988. A hazardous waste tank storage
facility has operated under interim status since 1982, but the facility's
owner/operator failed to submit a Part B permit application prior to the
1988 deadline.  Assuming the facility does not have an approved closure
plan, what deadlines must the owner/operator meet in submitting a closure
plan and conducting closure activities in accordance with Part 265, Subpart
G, following the loss of interim status in November  1992?

ANSWER: Because the owner/operator failed to submit a Part B permit
application prior to November 8, 1988, the tank storage facility loses
interim status on  November 8,1992 (§270.73(g)). Section 265.112(d)(3)
requires the owner/operator to submit a closure plan to the Regional
Administrator no later than 15 days after termination of interim status,

                            except when a permit is issued simultaneously. Accordingly, the
                            owner/operator of the tank storage facility was required to submit a closure
                            plan no later than November 23,1992.

                            Assuming the facility's closure plan is approved after November 8,1992,
                            the date of approval of the closure plan triggers the series of deadlines for
                            subsequent activities. Within 90 days following approval of the closure
                            plan, the owner/operator of the tank storage facility must treat, remove
                            from the facility, or dispose of on-site all hazardous wastes in accordance
                            with the approved closure plan (§265.113(a)).  Similarly, within 180 days
                            following approval of the closure plan the owner/opera tor must complete
                            closure activities in accordance with the approved closure plan
                            (§265.113(b)).  The Regional Administrator may approve longer time
                            periods if the owner/opera tor makes certain demonstrations, specified in
                            §§265.113(a)(l) and 265.113(a)(2) for treatment, removal, or disposal of
                            hazardous wastes and in §§265.113(b)(l) and 265.113(b)(2) for completion of
                            closure  activities.

                            After final closure of the tank storage facility is complete, the
                            owner/operator has up to 60 days to submit a certification of closure to the
                            Regional Administrator (§265.115).  This document, signed by both the
                            owner/operator and an independent registered professional engineer,
                            certifies that the facility has been closed in accordance with the
                            specifications of the approved closure plan.  Within 60 days after receiving
                            a satisfactory certification of  closure, the Regional Administrator will
                            notify the owner/operator in writing that he/she is no longer subject to
                            financial assurance requirements for final closure (§265.143(h)).

QUESTION:  EPA recently promulgated standards for a new hazardous
waste management unit called a containment building under 40 CFR Parts
264 and 265, Subpart DD (57 FR 37194; August 18,1992). EPA also amended
§262.34(a)(l),  allowing large quantity generators to accumulate and treat
hazardous wastes on-site in containment buildings for 90 days or less
without a permit or interim status. Must large quantity generators
accumulating  hazardous waste in containers or tanks under
§§262.34(a)(l)(i) or (ii) now construct containment buildings to house their
container or tank accumulation areas?

                            ANSWER: No, the new containment building regulations do not affect
                            hazardous waste container, tank, or drip pad management standards at
                            generator facilities and treatment or storage facilities operating under
                            permits or interim status.  EPA developed the containment building
                            standards to provide large quantity generators and treatment and storage
                            facilities with a new management unit for bulky, nonliquid hazardous
                            wastes (e.g., lead-bearing materials from batteries) not amenable to
                            accumulation, storage, or treatment in containers or tanks.  Although a
                            containment building can serve as a secondary containment system for
                            hazardous waste tanks under certain conditions, there is no federal
                            regulatory requirement to house existing containers, tanks, or other RCRA
                            hazardous waste management units within a containment building (57 FR
                            37215; August 18,1992). Containment buildings are intended to serve as
                            independent hazardous waste management units. A large quantity

"Containment  Buildings at Permitted  and  Interim  Status
Facilities"

QUESTION: EPA recently promulgated regulations for containment
buildings, a new type of hazardous waste management unit used for
treatment and storage of hazardous wastes.  What procedures must
permitted and interim status facilities follow when adding containment
buildings?

ANSWER: On August 18,1992, EPA promulgated a rule defining and
establishing management standards for a new type of unit called a
containment building (57 FR 37194; August 18,1992). A facility operating
under a RCRA permit may seek to add containment buildings to its
permitted operations in two situations — it may seek to convert existing
units (e.g., enclosed waste piles) to containment buildings, or it may seek to
construct new containment buildings. With respect to the first situation,
EPA believes that many facilities will convert their existing enclosed
waste piles to containment buildings (57 FR 37218). This will require a
Class 2 modification (57 FR 37218; 40 CFR §270.42, Appendix I, Item I, 6).
Construction to implement Class 2 changes generally may commence 60 days
after submission of the permit modification request (§270.42(b)(8)). If the
Agency does not respond within 90 days (or 120 days if the Agency requests

                            an extension), the facility is automatically authorized to conduct the
                            requested activity for 180 days.  During this time, the facility is required to
                            comply with applicable Part 265 standards in conducting the activity
                            (§270.42(b)(6)(iii)).  The construction of new containment buildings requires
                            a Class 2 or 3 permit modification, depending on whether the addition of
                            the buildings increases the facility's containment building storage or
                            treatment capacity by more than 25 percent (57 FR 37281; §270.42, Appendix
                            I,  Item M, 1).  Class 3 modifications are required at facilities with no
                            existing containment building capacity.  Class 3 permit modifications
                            require formal EPA approval; there is no deadline for Agency action and no
                            provision for automatic authorization in the absence of an Agency decision
                            (53 FR 37919).

                            Permitted facilities may apply for a temporary authorization under
                            §270.42(e). A temporary authorization may be granted for up to 180 days
                            and may be reissued for an additional 180 days provided that the facility
                            has submitted a request for a permit modification. Requests for temporary
                            authorization must demonstrate compliance with Part 264 standards and
                            also meet the  criteria in §270.42(e) for approval.

                            A facility operating under interim status may add new treatment processes
                            or additional treatment or storage capacity, such as containment buildings,
                            by using existing procedures for changes during interim status under
                            §§270.72(a)(2)  and (a)(3).  The facility must submit a revised Part A permit
                            application and a justification explaining the need for the change, which
                            must be approved by EPA before implementing any construction. According
                            to §270.72(b), changes generally may not be made if they amount to
                            reconstruction of the hazardous waste management facility.  The Agency
                            considers the facility "reconstructed" if the capital investment for the
                            changes to the facility exceed 50 percent  of the capital cost of a
                            comparable, entirely new hazardous waste management facility (57 FR
                            37242). The reconstruction limit does not apply, however, if the changes
                            are made in order to treat or store in tanks, containers, or containment
                            building provided that the changes are made solely to comply with Part
                            268  (§270.72(b)(6)).

                            Containment buildings are not considered newly regulated units. In the
                            August 18,1992, Federal Register, EPA simply reclassified existing units,
                            which may have been classified as indoor waste piles or certain
                            miscellaneous units, as containment buildings in order to facilitate
                            treatment of hazardous debris and other wastes. The procedural provisions
                            for newly regulated units are thus not applicable to owners and operators of
                            facilities that want to construct containment buildings.  For instance,

                            §§270.42(g) and 270.72(a)(6), which allow continued management of
                            hazardous wastes in newly regulated units without prior Agency action,
                            cannot be used to add containment buildings to a facility. Likewise,
                            facilities that do not currently manage hazardous waste and want to begin
                            managing hazardous waste in containment buildings or to construct
                            containment buildings for the management of hazardous waste may not gain
                            interim status. The facility must first obtain a RCRA permit before any
                            construction or waste management activities may begin (57 FR 36241-36242).

                            Generators also may add containment buildings for accumulating and
                            treating hazardous wastes. Under §262.34, generators may accumulate or
                            treat hazardous waste in on-site tanks or containers for up to 90 days
                            without a permit as long as the applicable Part 265, Subpart I (for
                            containers) or Subpart J (for tanks) standards are followed. The August 18,
                            1992, Federal  Register also applied this provision to containment buildings.
                            The units must be in compliance with Part 265, Subpart DD standards, and
                            with certain recordkeeping requirements. (June 1993 Monthly Hotline

"The  Use of Maximum  Contaminant Levels (MCLs) in
Groundwater  Monitoring"

QUESTION: Part 264, Subpart F outlines three phases of groundwater
monitoring for permitted land-based hazardous waste management units:
detection monitoring (§264.98), compliance monitoring (§264.99), and
corrective action monitoring (§264.100). When a facility enters into
compliance monitoring, the groundwater protection standard (GWPS) is
established in the facility permit.  Setting the GWPS involves designating
hazardous constituents (§264.93), concentration limits (§264.94), point of
compliance (§264.95), and the compliance period (§264.96). One of the
following must be used in developing the concentration limits for the
hazardous constituents: the background level of hazardous constituents
found at the facility (§264.94(a)(D), the maximum contaminant levels
(MCLs) in Table 1 of §264.94(a)(2), or an alternate concentration limit
(ACL) established in accordance with §264.94(a)(3).  MCLs were originally
established pursuant to the Safe Drinking Water Act (SOWA). Some of
these MCLs were incorporated into Table 1 of §264.94(a)(2) on July 26,1982
(47 FR 32274). Since 1982, several MCLs have changed under the SDWA
regulations, but  those changes have not been incorporated into Part 264,
Subpart F. In addition, there are a number of MCLs that have never been
incorporated into Table 1 of §264.94(a)(2). Can MCLs that have not been
codified in Table 1 of §264.94(a)(2) be used as concentration limits  when the
groundwater protection standard is established in the facility permit?

"Mixtures  of Used Oil and  Characteristic Hazardous  Waste"

QUESTION: A manufacturer generates used oil that exhibits the toxicity
characteristic (TC) for lead (D008). On one occasion, the used oil is mixed
with an unlisted spent solvent that is hazardous due to the characteristic
of ignitability (D001) and the TC for benzene (D018). On another occasion,
the used oil is mixed with a spent solvent that is hazardous solely because
it exhibits the characteristic of ignitability (D001).  After mixing, both
wastestreams exhibit only the TC for lead and are sent to be burned for
energy recovery in an industrial boiler.  Do both mixtures qualify for
regulation as used oil under 40 CFR Part 279 standards for used oil
management?

ANSWER:  The first mixture must be managed as hazardous waste (D008)
and the second mixture must be managed as used oil. Section 279.10(b)(2)
specifically addresses mixtures of used oil and characteristic wastes,
drawing a critical  distinction between the two mixtures described above.
The first mixture  is addressed in §279.10(b)(2)(i), which states that a
mixture of characteristic hazardous waste and used oil must be handled as
a hazardous waste if it displays any characteristics of hazardous waste.
This section applies to any mixture of used oil and characteristic hazardous
wastes, other than wastes that are hazardous solely because they exhibit
the characteristic of ignitability.  Since the first mixture contains a
characteristic hazardous waste that is hazardous because of ignitability
and toxicity, and the mixture continues to display the TC for lead, it is
considered hazardous waste. In order to qualify for classification as used
oil, this mixture must be free of all characteristics, including those
originating from the used oil (D008) and those stemming from the
hazardous waste (D001 and D018).

Section 279.10(b)(2)(iii) addresses the second mixture and is more specific.
It dictates that a mixture of used oil and a characteristic hazardous waste,
which is hazardous solely because it displays the characteristic of

                            ignitability, may continue to be managed as used oil provided that the
                            resulting mixture is not ignitable. Since the second used oil/waste mixture
                            is no longer ignitable, it is classified as used oil, even though it still
                            displays the TC for lead (D008).

                            The difference in these two scenarios is that used oil that is mixed with a
                            characteristic hazardous waste (other than a solely ignitable waste) must
                            be free of all characteristics to qualify for classification as used oil,
                            whereas used oil that is mixed with a waste that is hazardous solely due
                            to ignitability needs only to be void of the ignitability characteristic to be
                            considered used oil. The difference in the two scenarios is critical because
                            used oil often inherently exhibits a characteristic of hazardous waste.

                            The standards in Part 279, while tailored to used oil handling, do not
                            negate the requirements placed on handlers by the hazardous waste
                            regulations, and mixing an ignitable waste with used oil to render the
                            waste nonhazardous constitutes treatment of hazardous waste and is subject
                            to all applicable hazardous management standards, including permitting
                            (50 FR 49180; November 29,1985).

                            Note that Part 279 standards, other than those related to burning and
                            marketing, are effective March 8,1993, in unauthorized states only and in
                            authorized states they are not effective until those states amend their
                            program to incorporate the standards.  Standards regarding the marketing
                            and burning of used oil for energy recovery are simply transferred from
                            existing Part 266 regulations and remain in effect. (February Monthly

"Closed-Loop Recycling  Exclusion"

QUESTION: Under the closed-loop recycling exclusion in 40 CFR
§261.4(a)(8), secondary materials that are reclaimed and returned to the
original process or processes in which they were generated are excluded
from Subtitle C of RCRA, provided they are reused in the production
process and the criteria in 40 CFR §261.4(a)(8) are met. Would secondary
materials managed in a  system that includes  storage in open-top tanks fall
within the exclusion in §261.4(a)(8)?

                            "Closed-Loop  Recycling  Exclusion" (cont'd)

                            ANSWER: Secondary materials managed in a system that includes storage
                            in open-top tanks may qualify for the closed-loop recycling exclusion as long
                            as the system meets the four requirements in §261.4(a)(8). EPA views
                            closed-loop recycling operations as an integral part of production processes,
                            not as distinct waste management operations (51 FR 25443; July 14,1986).
                            Typically, owners or operators of such closed-loop recycling operations
                            handle the secondary materials as commodities; i.e., in a manner designed
                            to avoid loss or release. Although EPA does not preclude owners or
                            operators from storing secondary materials in open-top tanks under the
                            closed-loop recycling exclusion, there are other factors that prevent most
                            materials, especially volatiles, from being stored in them. These factors
                            include possible contamination from rain or dust and the threat of explosive
                            conditions. Owners or operators of open-top tanks should therefore ensure
                            secondary materials are managed as valuable materials prior to
                            reclamation in order for the tank to be considered a part of a closed-loop
                            recycling system and excluded under §261.4(a)(8).  Determinations
                            regarding the closed-loop recycling exclusion are usually case-specific.
                            Thus, if EPA discovers a situation where highly volatile materials are
                            stored in an open-top tank and large volumes of the materials are lost prior
                            to reclamation, the exclusion may not apply because the secondary
                            materials are not being managed to prevent loss or release prior to
                            reclamation, causing the material to become regulated as a waste under
                            Subtitle C of RCRA (51 FR 25443; July 14,1986). (February Monthly Hotline

"Natural  Gas  Condensate:  Regulatory  Status"

QUESTION:  Drilling fluids, produced waters, and other wastes associated
with the exploration, development, and production of crude oil, natural
gas, and geothermal energy are exempt from the definition of hazardous
waste under 40 CFR §261.4(b)(5). Natural gas condensate is a light
hydrocarbon liquid that sometimes forms through condensation of natural
gas (hydrocarbon) vapors when natural gas is conveyed through a pipeline.
Does natural gas condensate fall within the scope of this exemption when
discarded?

ANSWER: Natural gas condensate meets the exemption in §261.4(b)(5) if
it is produced by activities related  to the exploration, development, and
production of natural gas.  It does not meet the exemption if it is produced by
other activities, such as post-production transportation.  While not a
drilling fluid or a produced water, natural gas condensate can be produced
by activities associated with locating natural gas, removing it from the

                            ground, or purifying it. Natural gas is usually removed from the ground
                            using an array of wells in one gas field. The natural gas from all wells is
                            then aggregated and often sent to a gas plant to remove impurities such as
                            water. This removal of impurities is considered a necessary part of the
                            production process, and any .wastes resulting from natural gas operations up
                            through this point are exempt.

                            If condensate forms in a pipeline carrying natural gas from the gas field to
                            the gas plant, this natural gas condensate is exempt as an associated waste
                            under §261.4(b)(5). The key is that the activity producing the natural gas
                            condensate must be uniquely associated with natural gas exploration,
                            development, or production operations for the exemption to apply.  Natural
                            gas production operations encompass all processing facilities up to and
                            including the gas plant, but not beyond.

                            If the natural gas condensate is generated by transportation or
                            manufacturing operations beyond the production process, it is not exempt
                            and would be regulated as a hazardous waste when discarded if it displays
                            one or more characteristics of hazardous waste (58 FR 15284; March 22,
                            1993).  For example, if condensate forms in a pipeline transporting the
                            natural gas from the gas plant to market, this natural gas condensate is not
                            exempt since it is generated during post-production transportation and not
                            production operations. (July 1993 Monthly Hotline Report)

"Nitroglycerine Pills  as Commercial Chemical Products"

QUESTION:  A pharmaceutical company manufactures pills that contain a
low percentage  of nitroglycerine, with inert ingredients making up the
remainder of the content. The manufacturer must throw away a batch of
pills that has exceeded  its shelf life.  When discarded, are the pills a
hazardous waste? If so, what waste code would apply?

ANSWER:  The pills discarded by the manufacturer are a hazardous waste
with the waste code P081. Several hundred commercial chemical products
are listed in 40 CFR §§261.33(e) and (f).  Nitroglycerine is listed in
§261.33(e) with the waste code P081. The Comment in §261.33(d) defines
the term "commercial chemical product" as unused chemicals that are
either (1) pure or technical grades, or (2) formulations that contain the
listed chemical as the only active ingredient. The P- and U-listings apply
to such unused formulations of commercial chemical products regardless of
the concentration of the sole active ingredient; except for the listings for
warfarin and salts (P001 and U248) and zinc phosphide (P122 and U249),
there is no critical percentage or cut-off concentration of the sole active

                            nitroglycerine as the sole active ingredient. Since the pills have not been
                            used for their intended purpose (simply incorporating the nitroglycerine
                            into the formulation does not constitute use), and nitroglycerine is the only
                            component serving the function of the product (i.e., as medicine), the
                            discarded pills are appropriately classified as hazardous waste P081.

"Sample Holding Times and Validity of Analytical Results"

QUESTION: When characterizing waste as hazardous or nonhazardous
under RCRA Subtitle C, §262.11 provides that a generator has the option of
either applying knowledge of the hazardous characteristics of the waste or
testing the waste.  If the generator chooses to test a waste to determine if it
exhibits the toxicity characteristic under 40 CFR §261.24, the Toxicity
Characteristic Leaching Procedure - Method 1311 (TCLP) must be used to
generate a waste extract. This extract is then analyzed  for the 39
constituents listed in Table 1 of §261.24.  To ensure that accurate results are
obtained, there are specific quality control measures for the extraction and
analysis procedures, including limits on  the amount of time samples can be
held during testing.  When these sample holding times are exceeded, can
the results of constituent analysis on a TCLP extract still be used to
determine if a waste exhibits  the toxicity characteristic?

ANSWER:  When sample holding times are exceeded,  TCLP analytical
results will be considered the minimum  amount that could leach from the
waste; an identical sample analyzed within the prescribed holding times
might yield higher concentrations of toxicity characteristic constituents
(Part 261, Appendix II, §8.4). EPA's  manual Test Methods for Evaluating
Solid Waste: Physical/Chemical Methods (SW-846, Second Edition)
defines sample holding time as the storage time allowed between field
collection of a sample and completion of analysis in a laboratory.  Specific
maximum holding times are set for quality assurance and quality control
purposes.  Certain constituents in waste, such as volatile organic compounds,
can degrade or volatilize over time.  When constituents in a sample are lost
through these natural chemical processes, analytical measurements become
inaccurate. To limit sample degradation, maximum holding times are
developed based on the propensity of the waste constituents to degrade or
volatilize.  General guidelines for sample holding times are presented in
Volume 1, Chapters 2, 3, and 4 of SW-846, and additional method-specific
requirements may appear in the individual test methods themselves.

                            (cont'd)

                            TCLP sample holding times range from a total of 28 days for volatiles to 360
                            days for metals.  These overall time frames are further broken down,
                            specifying the length of time allowed for each step in the analytical
                            process. For example, volatile samples are allowed 14 days for leachate
                            extraction and another 14 days for constituent analysis, while the
                            breakdown for semivolatiles allows 14 days for leachate extraction, 7 days
                            for extract preparation, and 40 days for constituent analysis. When sample
                            holding times are exceeded, measurements may be inaccurate and the TCLP
                            analysis may be  invalid or inconclusive.

                            When analysis is conducted after a sample holding time is exceeded,
                            however, the results may still have limited applicability.  Because some
                            constituents are  lost through volatilization or degradation while awaiting
                            testing, constituent concentrations in expired samples will be lower than if
                            the sample were fresh. If a sample exceeds a recommended holding time
                            and analysis demonstrates that concentrations are above the regulatory
                            threshold for one or more constituents, then these concentrations can be
                            treated as minimum values and the waste is hazardous for the toxicity
                            characteristic.  No further testing is required.  If, on the other hand, a
                            sample exceeds a recommended holding time and analysis demonstrates
                            that concentrations are below the regulatory threshold for one or more
                            constituents, further testing may be necessary to demonstrate that the waste
                            is nonhazardous. If the generator chooses to conduct further testing,
                            additional samples would be required to ensure accurate measurement of
                            constituents and to provide a definitive waste determination under RCRA

"Unused  Formulations of Agent Orange"

QUESTION: During the Vietnam War an estimated 44 million pounds of
the herbicide Agent Orange were formulated for use as a defoliant.
Currently there are several United States military posts in possession of
unused formulations of this herbicide. Upon disposal, would the herbicide
Agent Orange be regulated as a hazardous waste under RCRA Subtitle C?

ANSWER: Unused formulations of Agent Orange would meet the F027
hazardous waste listing when disposed  of.  The active herbicidal
components of Agent Orange are equal quantities of 2,4,-
dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid
(2,4,5-T), which are both derived from the synthesis of chlorophenols and

"Waste Classified As Both  F005 and K086"

QUESTION: An ink manufacturer mixes inorganic pigments containing
chromium and lead in a tub.  After the ink is removed for use, the mixing tub
is cleaned with a solvent wash that contains 80 percent toluene prior to use.
The cleaning produces waste washes and sludges. When discarded, how
should the ink manufacturer classify the washes and sludges?

ANSWER:  The resulting washes and sludges generated from cleaning the
mixing tub would be classified as both F005 and K086.  The F005 listing
applies to spent nonhalogenated solvents containing, before use, 10 percent
or more by volume of one or more of a number of listed solvents, including
toluene. The K086 listing covers solvent washes and sludges, caustic washes
and sludges, and water washes and sludges generated by cleaning tubs and
equipment used in the formulation of ink from pigments, dryers, soaps, and
stabilizers containing chromium and lead.  According to the background
listing document for K086 (Identification and Listing of Hazardous Waste
S5261.31 and 261.32 - Listing of Hazardous Waste), when a tub used in
formulating ink from pigments containing chromium and lead is washed
with a solvent that will meet one of  the F001-F005 listings when spent, the
resultant solvent-wash wastes are considered hazardous wastes under the
applicable F-listing and the K086 listing. If a caustic or water wash is used
to clean the mixing tub instead of a solvent wash, the F005 listing would not
apply since solvents were not used.

Regardless of the type of wash used, for purposes of Part 268, the ink
manufacturer will also need to determine if the waste wash (K086) exhibits
any characteristics pursuant to 40 CFR §262.1 l(c). The waste must then
meet the applicable Part 268, Subpart D treatment standards for each
waste code that is subject to the land disposal restrictions under Part 268
prior to disposal in a Subtitle C facility. (Note the exception in §268.9(b)
for prohibited wastes that are both  listed and characteristic, where the
treatment standard for the listed waste operates in lieu of the treatment
standard for the characteristic waste if the treatment standard for the
listed waste addresses the constituent that causes the waste to exhibit  the
characteristic.) (May 1993 Monthly  Hotline Report)

"UST Financial Responsibility:  Local  Governments"

QUESTION: Local governments that own or operate underground storage
tanks (USTs) are subject to the same financial responsibility requirements
that apply to privately owned and operated USTs (40 CFR Part 280,
Subpart H). What is the compliance date by which local governments must
demonstrate financial responsibility?

ANSWER: On October 26,1988, EPA promulgated regulations creating a
variety of mechanisms that owners and operators of USTs could use to
demonstrate financial responsibility (53 FR 43322). The Agency realized,
however, that some of the mechanisms (e.g., the corporate test of self-
insurance) were not appropriate for use by local governments. As a result,
the Agency developed a rule that would establish four additional
mechanisms to help local governments comply. The Agency also extended
the compliance date for local governments to demonstrate financial
responsibility to one year after the promulgation of these four additional
mechanisms (55 FR 46022).

EPA published a final rule on February 18,1993, which added a worksheet
test, a bond rating test, a governmental guarantee, and a fund balance test to
the allowable financial responsibility mechanisms  (58  FR 9026).  For
purposes of calculating the compliance date, the mechanisms were
considered promulgated as of the publication date, February 18,1993.
Local governments must therefore  demonstrate financial responsibility by
February 18,1994, one year after the publication of the  new mechanisms.

                           petroleum, including crude oil or any fraction thereof that is a liquid at
                           standard temperature and pressure (HSWA §9001(2) and 40 CFR §280.12).
                           Mineral spirits, also known as stoddard solvent, naphtha, or white spirits,
                           is a refined petroleum distillate from the light end of crude oil. It is not
                           specifically identified as a hazardous substance under CERCLA §101(14).
                           Mineral spirits, however, is considered a petroleum fraction. Underground
                           tanks containing mineral spirits are therefore subject to regulation as

"Dense Nonaqueous  Phase Liquid  (DNAPL) Contamination  at
Superfund  Sites"

QUESTION: Groundwater remediation at Superfund sites can be much more
difficult when contaminants such as chlorinated solvents (e.g.,
tetrachloroethylene, methylene chloride, carbon tetrachloride), creosote,
coal tar, wood preserving wastes (e.g., pentachloro-phenol), and some
pesticides are present in their undiluted form.  These contaminants are
examples of compounds classified as dense nonaqueous phase liquids
(DNAPLs). What are dense nonaqueous phase liquids? How can the
likelihood of DNAPL presence at a Superfund site be estimated? What
special precautions must be taken when DNAPLs are suspected to be present
in the subsurface, and how should remediation be approached?  Are there
different cleanup standards for DNAPLs?

ANSWER: Dense nonaqueous phase liquids are contaminants that are
immiscible with and more dense than water in their undiluted form,
meaning they sink in water. A contaminant that is immiscible with water
does not readily mix with water, but  does slowly dissolve in it.  Other
contaminants such as crude oil, fuels, and other petrochemicals are light
nonaqueous phase liquids (LNAPLs)  which are less dense than water, hence
they float on the water table. DNAPLs, because of their dense nature,
migrate vertically downward, driven by gravity through soil and
groundwater. Once in the ground, DNAPL migration is influenced by
hydrogeologic features such as soil layering, impermeable layers, or
bedrock, and DNAPLs can penetrate fractures in clay layers or bedrock. As
DNAPLs migrate through the subsurface, a portion becomes trapped in pore
spaces or fractures in the soil, while the portion not trapped can continue to
migrate downward. The DNAPL that becomes trapped in the soil is called
residual DNAPL, while the portion of the contaminant that can continue to
migrate or form pools on impermeable layers (like clay) is called free-
phase DNAPL. Once the contaminant becomes dissolved in the   ,
groundwater, it enters the aqueous (or dissolved) phase and is no longer
categorized as a DNAPL.  The following figure provides further
clarification.

DNAPLs' strong tendency toward vertical migration can make site
characterization difficult.  The methods recommended for estimating the
likelihood of DNAPL contamination at Superfund sites include reviewing
the historical use of the site to determine if DNAPL chemicals were used,
stored, or disposed of; measuring the  relative concentration of contaminants
                                                                                        21

                            DNAPLs' strong tendency toward vertical migration can make site
                            characterization difficult. The methods recommended for estimating the
                            likelihood of DNAPL contamination at Superfund sites include reviewing
                            the historical use of the site to determine if DNAPL chemicals were used,
                            stored, or disposed of; measuring the relative concentration of contaminants
                            present in the soil; and measuring the relative concentration of
                            contaminants dissolved in groundwater for those contaminants that are
                            DNAPLs in their undiluted form (OSWER Directive 9355.4-07FS).

                            When DNAPLs are present in the subsurface, special precautions should be
                            taken during site characterization. When characterizing the subsurface,
                            EPA recommends that bore holes be drilled first in areas that are least
                            likely to contain DNAPLs, such as areas away from suspected sources (this
                            is referred to as an "outside-in" strategy).  Drilling in suspected DNAPL
                            areas should be minimized. When drilling in site areas where DNAPLs are
                            suspected, drilling should cease when an impermeable layer such as clay is
                            encountered. If the bore hole penetrates the impermeable layer and free-
                            phase DNAPL is present, then the gravity-driven DNAPL will migrate
                            down the hole. EPA also recommends that noninvasive methods such as
                            geophysical or geochemical surveys be used to characterize subsurface
                            conditions in order to reduce the number of bore holes needed for this
                            purpose, and to minimize the risk of causing further DNAPL migration.

                            When DNAPL contamination is confirmed or highly suspected, the
                            recommended approach to remediation at Superfund sites is to (1) contain
                            the dissolved contamination plume, (2) contain or isolate areas containing
                            subsurface DNAPLs from the dissolved plume, (3) extract the free-phase
                            DNAPL to the extent possible, (4) where appropriate, restore groundwater
                            in the dissolved plume to its current or potential use, and (5) consider using
                            innovative cleanup technologies to remove as much DNAPL source material
                            as possible.  EPA also recommends that containment of the contamination
                            plume be implemented as an early action.

                            The cleanup standards for the remediation of DNAPL-contaminated
                            groundwater are dependent on the current or potential use of the
                            groundwater. For example, groundwater that is a potential future source of
                            drinking water usually must meet chemical-specific cleanup standards that
                            are relevant and  appropriate for drinking water. Such cleanup standards
                            are generally attainable over site areas where only dissolved contaminants
                            are present in groundwater. For those site areas where DNAPLs are present
                            in their undiluted form and cannot be removed, it may be appropriate to
                            consider waiving cleanup standards due to technical impracticability from

"Land Disposal Restrictions as ARARs at Superfund Sites"

QUESTION: During a remedial investigation at a National Priorities List
(NPL) site, activities generate soil contaminated with a restricted RCRA
hazardous waste. The soil is stored in containers within the area of
contamination (AOC) for several months, and subsequently returned to its
source. Does this on-site disposal activity require compliance with RCRA
land disposal restrictions (LDR)?

ANSWER: In order to trigger LDR, on-site disposal activity must constitute
placement of a restricted waste in a land disposal unit. According to the
National Contingency Plan (NCP), placement occurs when wastes from
different AOCs are consolidated into one AOC, when wastes are moved out
of an AOC (for treatment or storage) and returned to the same or different
                                                                                       23

                            within the AOC, and then redeposited into the same AOC (55 FR 9759;
                            March 8, 1990).

                            The NCP further states that placement does not occur when wastes are
                            treated in situ, capped in place, consolidated within the AOC, or processed
                            within the AOC to improve its structural stability (but not in a separate
                            hazardous waste management unit, such as a tank). The scenario presented
                            in this question does not constitute placement because the definition of a
                            hazardous waste management unit, such as a tank). The scenario presented
                            in this question does not constitute placement because the definition of a
                            hazardous waste management unit (40 CFR §260.10) states that "[a]
                            container alone does not constitute a unit; the unit includes the containers
                            and the land or pad upon which they are placed." Therefore, returning
                            waste that has been stored within the AOC in containers (not tanks or other
                            RCRA-regulated units) to its source does not constitute land disposal, as
                            long as the containers are not managed in such a manner as to constitute a
                            RCRA storage unit as defined in 40 CFR §260.10. (January 1993 Monthly

"State Authority  in  Selecting the  Remedy  at  State-lead
Superfund  Sites"

QUESTION: CERCLA §121(0 provides for "substantial and meaningful"
involvement by each state in the initiation, development, and selection of
remedial actions to be undertaken at Superfund sites in that state. In
addition, CERCLA §104(d)(l) provides for states to assume the lead at
Fund-financed sites through Cooperative Agreements. The lead agency is
responsible for preparing the Record of Decision (ROD) and other primary
documents. If a state is designated as the lead agency at a Fund-financed
site and there is controversy over the remedy, does the final authority over
remedy selection  rest with EPA or the state agency?

ANSWER:  EPA  retains final decision-making authority in selecting the
remedy at Fund-financed sites even when the state is the lead agency.
Before a state may proceed with a Fund-financed response action, EPA must
first concur with  and adopt the ROD. Pursuant to 40 CFR §300.515(e)(2)(ii),
unless EPA's Assistant Administrator for Solid Waste and Emergency
Response or Regional Administrator concurs in writing with a state-
prepared ROD, EPA is not deemed to have approved the state decision and
the remedy may not be initiated.  According to the preamble to the

                            for the federal Superfund program." In addition, the NCP notes that
                            retaining authority for final remedy selection within EPA (rather than
                            dispersing it among the 50 states and EPA) furthers the goal for consistent
                            implementation of remedies at sites (55 FR 8666,8783). (June 1993 Monthly

"De  Micromis Superfund Settlements"

QUESTION:  EPA generally chooses not to pursue enforcement activities
against those potentially responsible parties (PRPs) who contributed only
minuscule amounts of hazardous substances to a Superfund site. Despite this
policy, very small PRPs remain vulnerable  to  third-party contribution
actions in which larger PRPs sue to recover cleanup expenses. The mere
legal fees incurred by minor PRPs in such contribution suits may easily
exceed the portion of cleanup costs they could expect to pay under a typical
EPA settlement or judgment.   How can very  small PRPs achieve fair
resolution of their Superfund liability and protection from contribution
actions?

ANSWER: PRPs who contributed only minuscule amounts of hazardous
substances to a Superfund site are called "de micromis" parties. De
micromis is a term EPA coined to denote PRPs who  made a minuscule
contribution to a Superfund site and to distinguish  them from de minimis
PRPs. De micromis PRPs may be eligible for de micromis settlements with
EPA that provide resolution of liability and contribution protection. De
micromis settlements form a subset of de minimis waste contributor
settlements. De minimis settlements are used to expeditiously resolve the
liability  of PRPs who meet the statutory eligibility criteria of CERCLA
§122(g)(l)(A). A de minimis waste contributor PRP's contribution of
hazardous substances to a site must be minimal in amount and toxicity
relative to other hazardous substances at the facility. The total value of a
de minimis settlement must also represent only a minor portion of overall
response costs for the site in question. De minimis settling parties typically
provide EPA with a cash payment commensurate with their contribution of
waste to a site. EPA typically grants the settling parties a covenant not to
sue for past and future civil liability relating to the cleanup, as well as
contribution protection. De minimis waste contributor settlements generate
                                                                                          25

                             costs for both the PRPs and EPA.

                             Since the de micromis settlement is a type of de minimis settlement, PRPs
                             seeking to resolve their liability as de micromis contributors must meet the
                             CERCLA §122(g)(l)(A) eligibility  criteria described above. In addition,
                             PRPs qualify for de micromis settlements only if their hazardous substance
                             contribution is below a maximum cut-off level established on a case-by-case
                             basis for each Superfund site. EPA's Guidance on CERCLA Settlements
                             with De Micromis Waste Contributors (OSWER Directive 9834.12; NTIS
                             PB93 963 619) provides some examples of how de micromis contribution cut-
                             off levels might be determined. A typical cut-off level is 0.001 percent of
                             the total hazardous substance contribution; however, EPA has wide
                             latitude in selecting a level appropriate to the site using a variety of
                             equitable factors. For example, when PRPs have contributed only
                             municipal solid waste to a site, the de micromis cut-off level may be
                             adjusted to account for the relatively low toxicity of their hazardous
                             substance contributions.  In general, de micromis PRPs include small
                             businesses, nonprofit organizations, and other entities that do not use
                             significant amounts of hazardous substances. Although federal agencies
                             and industrial PRPs can qualify as de micromis parties if they meet all
                             eligibility requirements, de micromis settlements are never available to
                             owners or operators of Superfund sites.

                             The payment amounts required of de micromis parties are usually based on
                             the percentage  of their contribution to overall site contamination. When
                             all PRPs have contributed similar hazardous substances to a site, the de
                             micromis settlement determination can be fairly straightforward. For
                             example, a typical de micromis PRP responsible for 0.0001 percent of total
                             hazardous substances at a site  would pay that percentage of overall
                             cleanup costs. If maximum site response costs were estimated at 30 million
                             dollars, the de micromis party  would settle with EPA for 30 dollars.
                             Because contribution percentages are not always accurate indicators of a de
                             micromis party's responsibility for contamination, payment calculation can
                             be adjusted to reflect site-specific factors. For example, when de micromis
                             parties have  contributed only household waste to a site, their settlement
                             payment calculation may be adjusted to reflect the comparatively low
                             toxicity of their contribution. A PRP's inability to pay can also be
                             considered when calculating settlement amounts.  EPA typically grants the
                             de micromis PRP a covenant not to sue, which includes a reopener clause
                             allowing EPA to pursue enforcement action if new information should arise
                             regarding the party's eligibility for the de micromis settlement. De
                             micromis settlements also provide protection from third-party contribution
                             suits under CERCLA §§113(f) and  122(g)(5).

                             Under traditional Superfund enforcement policy, minuscule hazardous
                             substance contributors were not usually notified of their potential liability.
                             EPA generally chose not to expend enforcement resources pursuing such PRPs.
                             EPA's current policy is to exercise its discretion to enter into de micromis
                             settlements in a number of situations. EPA may elect to identify eligible de
                             micromis parties and offer them protection from third-party contribution
                             actions through a de micromis settlement early in the enforcement process.
                             Community relations mechanisms can be used to publicize the availability
                             and benefits of de micromis settlements in such situations. EPA can also
                             offer de micromis settlements later in the Superfund process to eligible
                             parties already threatened or involved  with contribution suits. Finally,
                             qualified parties may at any time approach EPA and seek liability
                             resolution and contribution protection through de micromis settlements.

"Liability Exemption Under CERCLA for  Service Station  Dealers
Managing  Used Oil"

QUESTION:  CERCLA §114(c) exempts service station dealers from certain
CERCLA liability provisions, specifically response costs, damages, and
injunctive relief resulting from a release or threatened release of recycled
used oil, if the dealer meets specific requirements. The exemption is
applicable to  generator liability under §107(a)(3) and transporter liability
under §107(a)(4), and covers claims for both cost recovery under §107 and
the injunctive relief provision in §106(a). The service station dealer (SSD)
could still be held responsible for both injunctive relief under §106 and cost
recovery under §§107(a)(l) and (2) arising from owner and operator
liability.  What requirements must an SSD meet in order to qualify for this
exemption?

ANSWER:  A service station dealer must satisfy three requirements to
qualify for the exemption under CERCLA §114(c). First, the dealer must
meet the definition of an SSD, which is defined in CERCLA §101(37) as any
person who owns or operates a filling station, garage, or similar retail
establishment that derives most of its business from fueling and servicing
motor vehicles.  The term also includes any government agency that
establishes a facility solely for the purpose of accepting used oil. To meet
the SSD definition, the  owner or operator  must also accept used oil from do-
it-yourself (DIY) used oil handlers (i.e., people who remove used oil from
household appliances or change their own oil) and deliver that used oil to
a recycling facility.

The second requirement under §114(c)(l)(A) limits the exemption to used oil
that is not mixed with  a CERCLA hazardous substance. Section 114(c)(2)
does allow the SSD to presume that certain used oil received from a DIY
                                                                                           27

                            Managing Used Oil" (cont'd)

                            generator has not been mixed with a hazardous substance. The presumption
                            specifically states that the used oil must be removed from the engine of a
                            light duty motor vehicle or a household appliance, and must be presented
                            to the SSD by the owner of the vehicle or appliance for collection,
                            accumulation, and delivery to a  used oil recycling facility.

                            The third requirement in §114(c)(l)(B) limits the exemption to used oil
                            managed in compliance with regulations or standards promulgated pursuant
                            to RCRA §3014 and other applicable authorities. Although this exemption
                            has been part of CERCLA since the Superfund Amendments and
                            Reauthorization Act was passed  in 1986, SSDs were not eligible to assert
                            the exemption because comprehensive used oil management standards were
                            not promulgated until 1992 (57 FR 41566,41583). In 1985, EPA promulgated
                            standards pertaining to burning used oil for energy recovery (40 CFR Part
                            266, Subpart E), but these standards did not include requirements for
                            corrective action for releases of used oil. The used oil management
                            standards must provide corrective action standards in order to be considered
                            comprehensive and trigger applicability of the liability exemption
                            (CERCLA §114(c)(4)).  On September 10,1992, however, EPA issued
                            comprehensive standards for the management of recycled used oil, codified
                            as 40 CFR Part 279, under the authority of RCRA §3014 (57 FR 41566). In
                            the rule, EPA prescribes standards for generators, collectors, transporters,
                            processors, burners, and marketers of used oil that is being recycled. The
                            new Part 279 standards also require corrective action by incorporating
                            release response requirements into the regulations and by cross-referencing
                            both 40 CFR Part 280, Subpart F for releases from underground storage tanks
                            and 40 CFR Part 112 for spill prevention, control, and countermeasures.

                            SSDs in states without an authorized RCRA program are eligible for the
                            liability exemption as  of March  8, 1993, the effective date of the new Part
                            279 standards (§114(c)(4)). Because Part 279 was promulgated under RCRA
                            authority, RCRA- authorized states need  to adopt the new used oil
                            regulations before they become  effective  in that state.  SSDs in authorized
                            states still qualify for the exemption, however, if they can demonstrate
                            compliance with new Part 279 standards, regardless of the state's
                            authorization status (57 FR 41583).

                            Once the three requirements outlined in CERCLA §114(c) have been met, an
                            SSD can qualify for the liability exemption. Section 114(c)(l), however,
                            only exempts SSDs from generator and transporter  liability, not from
                            liability as owners and operators of a facility. Thus, the exemption
                            applies only to releases at facilities to which the SSD has sent its used oil
                            for recycling or for management prior to recycling, not releases at the SSD's
                            own facility. (May 1993 Monthly Hotline Report)

"TAGs Status  at  Superfund Sites Deferred to  RCRA"

QUESTION: EPA, under the authority of CERCLA §117(e), may award a
technical assistance grant (TAG) of up to $50,000 to qualifying groups of
individuals affected by a National Priorities List (NPL) site to obtain
assistance in interpreting and disseminating information related to site
activities. When a site is listed  or proposed for listing on the NPL, EPA
has the "discretion to use its authorities under CERCLA, RCRA, or both to
accomplish appropriate cleanup at a site" (55 FR 8698; March 8,1990). A
proposed or listed NPL site thus could be deferred to RCRA corrective
action authorities for cleanup.  What is the status of a TAG  awarded at a
proposed NPL site that is subsequently deferred to RCRA jurisdiction? Does
the TAG remain valid, or must the grant money be returned to the
Superfund?

ANSWER: As a policy, EPA does not provide TAGs for sites likely to be
deferred to another authority.  Nevertheless, once a TAG is appropriately
awarded at a site, it will remain valid until the site no longer requires
cleanup attention or poses a threat to human health and the environment.

Continuation of TAGs at sites that are deferred to RCRA is consistent with
the objective of community involvement in the Superfund program. The
January 3,1990, memo from Don Clay to Norman Mineta states that
"...terminating the grants based on administrative decision, rather than on
cleanup of the sites, would convey a message entirely inconsistent with our
commitment to public and community involvement in the process of cleaning
up the nation's hazardous waste sites." If cost recovery action is initiated
for the site, however, the cost of the TAG will be included in the recovery
action. (July 1993 Monthly Hotline Report)
"Accelerating  Superfund  Cleanups"

QUESTION: What is the Superfund Accelerated Cleanup Model (SACM),
and how is it being implemented? Is information about the initiative
available?
                            ANSWER: SACM, a new process for conducting Superfund site cleanups,
                            expands the use of the removal program to accelerate the pace of cleanups.
                            The overall goal of SACM is to speed cleanups and increase efficiency in
                            the Superfund process. Under SACM site assessment activities will be
                            consolidated to support both short-term cleanup activities and long-term
                            remedial actions.  EPA is testing the new model within the framework of
                                                                                        29

                            CERCLA and the National Contingency Plan (NCP). This ensures that
                            cleanups continue to be protective of human health and the environment
                            and to allow for appropriate public involvement.

                            Implementation of SACM initiatives are the responsibility of the newly
                            created Regional Decision Teams (RDTs). These teams decide whether a
                            response is necessary, provide cross-program coordination of response
                            planning, and ensure that response actions are consistent with the
                            requirements contained in CERCLA and the NCP. These RDTs are currently
                            responsible for implementing 13 pilot projects focused on use of SACM at
                            several Superfund sites. At some of these pilots presumptive remedies are
                            being used. This concept identifies cleanup techniques proven to be
                            effective, and applies these  techniques at sites with similar conditions,
                            reducing the amount of time spent on selecting alternatives. Presumptive
                            remedies are currently being applied at pilot projects involving wood
                            treatment, municipal landfill, solvent, and groundwater sites. SACM
                            implementation does not change the Superfund program's emphasis on
                            enforcement first. When applying the principles of SACM, EPA is
                            dedicated to maximizing potentially responsible party (PRP) involvement.

                            EPA has made considerable effort to communicate the progress, goals,
                            objectives, and expectations  for implementing SACM to federal and state
                            agencies, environmental groups, and the general public.  EPA published a
                            series of fact sheets under publication number 9203.1-051 (Volume 1,

"Revitallzation  Initiatives  for  Superfund"

QUESTION: What are the latest developments in EPA's Superfund
revitalization effort? How can information about this initiative be
obtained?

ANSWER:  In early 1992, EPA announced an initiative aimed at
revitalizing the Superfund program by focusing on the goal of reducing the
greatest amount of risk to human health and the environment in an
30

-------
                   SUPERFUND  (SF)
"Revitalization Initiatives for Superfund" (cont'd)

expedited, cost-effective manner. The Superfund Revitalization Office,
consisting of EPA Headquarters and Regional personnel and representatives
from other federal agencies was created to coordinate this initiative.
Multiple EPA offices including the Superfund Revitalization Office, the
Office of Emergency and Remedial Response, the Office of Waste Programs
Enforcement, and the Office of Enforcement are working toward this
common goal.

The objective of the revitalization plan is to make the Superfund process
more effective, efficient, and equitable. To improve program effectiveness
and accelerate the cleanup of Superfund sites, EPA is rethinking the way
sites are evaluated and addressed. To better communicate the successful
completion of cleanup activities to the public, EPA recategorized sites
presently or formerly on the National Priorities List (NPL) and created the
Construction Completion List (most recently published on March 2,1993; 58
FR 12142). EPA is also improving the effectiveness of Superfund risk
assessment and risk management. To achieve efficiency in contracts
management procedures, EPA developed and implemented a long-term
contracting strategy, improved the alternative remedial contracting
strategy award fee process and lowered program management costs, and is
developing several useful tools to enhance the speed and quality of the
contract lab program analytical services. EPA targeted early enforcement
as an important part of the equity initiative with increased use of de
minimis settlements, study of mixed funding options, and  voluntary
cleanups. To test different aspects of  the revitalization effort, EPA
initiated 32 pilot projects which address over 60 Superfund sites.

In order for EPA to communicate its achievements to the public and solicit
suggestions on how to make more improvements, an outreach strategy has
been developed. Public forums are being held around the country involving
representatives of states, local governments, industry, environmental
groups, and the general public. The next forum is scheduled for
May 19 and 20,1993, in Dallas. To provide guidance on Superfund
revitalization initiatives EPA published a fact sheet entitled Smart
Moves in Superfund: Revitalization One Year Later (publication number
9202.1-021, January 1993) EPA also published the Compendium of Good
Ideas: Volumes 1 and 2 (publication numbers 9202.1-10-1 and 9202.1-10-2,
March 1993) which compiles information from meetings with each
Regional office, including innovative ideas, successes, lessons learned, and
concerns for the Superfund program. These guidance documents are
available from the National Technical Information Service (NTIS). For

"Chemicals Listed  with  Multiple Chemical Abstract Service
Numbers"

QUESTION: The Chemical Abstract Service (CAS) maintains a
computerized filing system that contains two main index files. The
chemical abstract (CA) file provides bibliographic information referencing
chemicals appearing in over 9,000 journals, papers, and symposiums from
1967 to the present. The CA file is an important tool for people interested
in learning about the research, patents, and uses for specific chemicals. The
chemical registry number file assigns CAS registry numbers to unique
chemicals for purposes of identification. Assigning a CAS number to a
particular chemical facilitates managing and regulating that chemical by
universally identifying it with a specific number.  Only one CAS number is
assigned to each chemical.  If chemicals are to be assigned only one CAS
number, why are some chemicals listed with multiple Chemical Abstract
Service (CAS) numbers in 40 CFR Table 302.4 and the Title III List of Lists?

ANSWER: There are two possible reasons for a chemical to have multiple
numbers. The CAS numbers could refer to different forms of a chemical
where each is considered unique for its  particular properties and
characteristics.  The CAS registry number file includes the registry number,
synonyms, chemical structure, and molecular formula for each chemical
recorded in the  file. If specific research has been done on a particular form
of a chemical, a separate CAS number may be assigned to that particular
form to facilitate the search process in the CA file. For example, sodium
hypochlorite is listed with two CAS numbers, 7681-52-9 and 10022-70-5.
The former refers to hypochlorous acid, the sodium salt form of sodium
hypochlorite, while the latter refers to  the pentahydrate form of sodium
hypochlorite. Both forms could be called sodium hypochlorite, thus
sodium hypochlorite has, in effect, two CAS numbers.

A chemical also may be listed with multiple CAS numbers when multiple
numbers have been inadvertently assigned to the same chemical. This
multiple assignment can occur when forms of a chemical are originally
believed to be unique, but after further  review by chemists are identified as
the same chemical.  In this case, all the CAS numbers are cross-referenced,
                                                                                     33

                            referencing purposes.  The CAS number first assigned is the more accurate
                            number to use when denoting the chemical. Although all of the numbers
                            will find the chemical, only the more accurate number will prompt the CAS

                            associated with the chemical. Chromic acid, listed with CAS numbers
                            1115-74-5 and 7738-94-5, illustrates this situation. After further review by
                            chemists, the second CAS number, 11115-74-5, was deleted as a registry
                            number, but remains on file for future reference. CAS number, 7738-94-5 is
                            the more accurate number to identify chromic acid because it was the first
                            registry number assigned.  (February 1993 Monthly Hotline Report)

        "Designation  of Facility Emergency Coordinator"

        QUESTION: According to EPCRA §303(d)(l) and 40 CFR §355.30(c), the
        owner or operator of a facility must designate a representative to
        participate in the local emergency planning process as a facility emergency
        coordinator. The regulatory deadline for notifying the Local Emergency
        Planning Committee (LEPC) of this representative is on or before September
        17,1987, or 30 days after establishment of the LEPC, whichever is earlier.
        If a facility first becomes subject to the emergency planning requirements
        after September 17,1987, when must the owner/operator of this newly
        regulated facility provide notification designating the emergency response
        coordinator?

        ANSWER: A facility that becomes subject to the emergency planning
        requirements of EPCRA after September 17,1987, must provide the name of
        its coordinator  to the LEPC within 60 days. This is the same deadline
        provided under EPCRA §302(c) for a newly subject facility to notify the
        State Emergency Response Commission (SERC) and LEPC that it is subject to
        emergency planning.

        The different deadline under §303(d)(l) for providing the name of the
        emergency coordinator to the LEPC was only to provide for transition at the
        time EPCRA was enacted. The statutory deadline for the §302(c)
        emergency planning notification to the SERCs was May 17,1987, a few
        months prior to the August 17,1987, date on which the LEPCs were required
        to be operational. Thus, the emergency planning notification had to be
        given to the SERCs before the LEPCs were formed. Since notification of the
        designated facility emergency coordinator is provided to the LEPC and not

                           QUESTION: If polymers are in pellet form and require material safety
                           data sheets, are they exempt from the definition of hazardous chemical
                           under SARA §311(e)(2)?

                           ANSWER:  The §311(e)(2) exemption from the definition of hazardous
                           chemical applies to "[a]ny substance present as a solid in any manufactured
                           item to the extent exposure to the substance does not occur under normal
                           conditions of use." Polymers in pellet form are manufactured items in a
                           solid state and would not normally be a source of any hazardous chemical
                           exposure, therefore the polymers in pellet form are normally exempt (52 FR
                           38344; October 15, 1987). Altering the solid state of the pellets (e.g., as part
                           of a manufacturing process) creates a potential for exposure  and would cause
                           the polymers to become subject to the hazardous chemical threshold
                           determinations (40 CFR §370.20(b)). When determining whether a
                           threshold has been met, the weight of the polymer pellets "in process" are
                           no longer exempted as solid manufactured items and should be added to the
                           weight of the polymers not in pellet form and not otherwise exempt. If at
                           any one time the polymers not subject to an exemption exceed the
                           thresholds, then hazardous chemical reporting is required  (40 CFR Part
                           370). (February 1993 Monthly Hotline Report)

"Proprietary  Compounds  and  EPCRA §§311/312  Reporting"

QUESTION: A facility is storing a product mixture on-site. Under OSHA
regulations, the facility is required  to retain a  material safety data sheet
(MSDS) for the mixture. According  to the MSDS, the mixture contains a
zinc compound, but no specific chemical identity or concentration
information is provided. OSHA regulations allow chemical manufacturers
to withhold this information from the MSDS under a trade secrecy claim
(29 CFR §1910.1200(i)).  From the MSDS, the owner/operator cannot tell
whether the proprietary compound  is a hazardous chemical (such as zinc
silicofluoride) or an extremely hazardous substance (such as zinc
phosphide).

To comply with EPCRA §§311 and 312 reporting requirements, the facility
must determine whether this mixture exceeds the appropriate inventory
threshold level. How would the facility make  this determination?  Once a
quantity is calculated, should it be compared to the hazardous chemical
threshold of 10,000 pounds, or should the facility owner or operator assume
the compound is an extremely hazardous substance (EHS) and apply the
lower threshold?

ANSWER:  Pursuant to 40 CFR §§370.28(a)(l) and (2), a facility may report
on a mixture as a whole or on each hazardous component of the mixture.
The option of reporting by components, however, is not available if the
components are not known.  In this case, since the MSDS contains no
information on the concentration of the proprietary zinc compound, the
facility must report the mixture as a whole.

The next step in evaluating whether a facility is required to report under
EPCRA §§311 and 312 is to compare the quantities stored on-site to the
appropriate threshold level codified in 40 CFR §370.20(b). For hazardous
chemicals that  are not  EHSs, reporting is required if the facility has over
10,000 pounds on-site at any one time. For extremely hazardous substances,
reporting is necessary  if the facility has the chemical on-site in quantities
over 500 pounds or the threshold planning quantity (whichever is lower).
                            In this scenario, the specific identity of the chemical is not available to
                            the facility owner or operator.  Because the facility receives an MSDS for
                            the mixture, the owner or operator knows that the mixture contains a
                            hazardous chemical. While the owner or operator has a duty to make all
                            reasonable efforts to determine whether or not the substance is an EHS, if

                            mixture as an EHS. For the zinc compound mixture, the facility could
                            assume the mixture contains a hazardous substance and apply the 10,000-
                            pound threshold level to the overall weight of the mixture. In addition,
                            the facility must state that it is "unknown" whether the mixture contains
                            an EHS by writing this in the appropriate box on the applicable form.

"Sheet  Metal  Reporting  and the  Exemption  for Manufactured
Solids  Under  §§311/312"

QUESTION:  A facility stores and processes sheet metal that contains a
hazardous chemical requiring a material safety data sheet (MSDS) under
OSHA's Hazard Communication Standard (29 CFR §1910.1200(c)). The
sheet metal, when in storage, is considered a manufactured solid and is
therefore excluded from the definition of hazardous chemical under EPCRA
§311(e)(2). Does this exclusion still apply when the sheet metal is cut,
welded, or brazed?

ANSWER: The exclusion for manufactured solids in EPCRA §311(e)(2)
applies to "[a]ny substance present as a solid in any manufactured item to
the extent exposure to that substance does not occur under normal conditions
of use."  Sheet metal is considered a "manufactured item" which is
typically present as a solid. To determine whether or not the sheet metal
falls under this exemption, the owner/operator of the facility must
determine the extent of exposure to the substance under normal conditions of
use at that facility. Storing, welding, and cutting can all be considered
"normal conditions of use" at a facility.  In this example, only the sheet
metal in storage is exempt under §311(e)(2) because it does not create a
potential for exposure to a hazardous chemical. Cutting, welding, brazing,
or otherwise altering the form of the sheet metal does create a potential for
exposure, negating the exclusion under §311(e)(2) and subjecting the weight
of the maximum amount of sheet metal used in this fashion at any time to
reporting requirements under 40 CFR  §370.20(b).

The regulations at 40 CFR §370.20(b) state that a facility must submit an
MSDS and a Tier I form (or Tier II form) for any hazardous chemical present
at a facility in an amount greater than 10,000 pounds and for any extremely
hazardous substance present at the facility in an amount greater than or
                                                                                        37

"Light Fixtures as Structural Components Under EPCRA §313"

QUESTION: To reduce the use of polychlorinated biphenyls (PCBs) at a
facility, the owner/operator removed the light fixtures equipped with
PCB-filled ballasts and replaced them with light fixtures free of PCBs.
The ballasts were disposed of off-site. Must the owner/opera tor report the
PCBs found in the light fixture ballasts as otherwise used when making
EPCRA §313 threshold and release determinations, or would this use of
PCBs be exempt under 40 CFR §372.38(c)?

ANSWER: For purposes of EPCRA §313, the term "otherwise use" means
any use of a listed toxic chemical at a facility that does not fall under the
definitions of "manufacture" or "process" (40 CFR §372.3). In developing
the definition of otherwise use, EPA exempted certain uses of toxic
chemicals to narrow the types of activities covered by the threshold (40
CFR §372.38(c)).  The structural component exemption limits the definition
of otherwise use by excluding those activities involving toxic chemicals
found at a facility in passive structures or equipment (53 FR 4500, 4506;
February 16, 1988). The PCBs found in the light fixture ballasts are
structural components of the facility and are therefore excluded from
EPCRA §313 threshold and release determinations pursuant to 40 CFR
§372.38(c)(l). Reporting the off-site disposal of these PCBs is not required
under EPCRA §313. (November 1993 Monthly Hotline Report)

however, the air conditioning unit is integral to the facility's operation or

"Repackaging  as Processing"

QUESTION: A manufacturing facility receives shipments of an EPCRA
§313 listed toxic chemical in rail cars. The toxic chemical is transferred
from the rail cars into large tank trucks for distribution to customers. The
.quantity of the toxic chemical held in the tank trucks is approximately
equivalent to the amount held in the rail cars.  Would the transfer of the
toxic chemical from the rail cars to the tank trucks be considered
repackaging and therefore included in processing threshold
determinations?

ANSWER:  All activities involving the  preparation of a listed toxic
chemical, after its manufacture, for distribution in commerce are to be
included in the processing threshold determination for that chemical. The
Agency defines processing to include "...the preparation of a chemical for
distribution  in commerce in a desirable form, state, and/or quantity (i.e.,
repackaging)..." (53 FR 4506; February 16,1988). The act of removing a toxic
chemical from one container and placing it in another is considered
repackaging, regardless of the size of the containers involved.  As such, the
facility must include any amounts transferred from the rail cars to the tank
trucks in its  processing threshold for that chemical.  (March 1993 Monthly

"Reporting 'Not Applicable'  in  Section 8.8 of the  Form R"

QUESTION: On the Form R, a facility owner/operator must provide
information about routine and nonroutine releases for each reported toxic
chemical. Specifically, in Section 8.8, an owner/opera tor must report the
quantity of any release of a toxic chemical into the environment or
transferred off-site as a result of a remedial action, catastrophic event, or
one-time event not associated with production processes.  If the facility did
not experience any such release or transfer, must the owner/opera tor report
zero, or may the owner/operator report "not applicable" (NA) in Section
8.8?

ANSWER: While either notation, NA or zero, may be entered in  Section
8.8 of the Form R, they are not synonymous. If a remedial action,
catastrophic event, or one-time event not associated with production
processes results in a release into the environment or an off-site transfer of
the toxic chemical and the annual  aggregate release was less than 0.5
pound, then a facility owner/operator should enter zero in Section 8.8. An
owner/operator should only report NA for Section 8.8 on the Form R if no
release or transfer occurred as a result of these activities. (July 1993

            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 key word. For example, to find questions dealing with solvents,
you would look in the key word index for the word "solvent" and find two questions
referenced under that subject: "Dense Nonaqueous Phase Liquid (DNAPL) Contamination at
Superfund Sites" and "Waste Classified as Both F005 and K086." 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=Superfund, U=UST, and E=EPCRA).

The second index organizes the questions and FR summaries by regulatory citation,
beginning with 40 CFR Part 238.  This index is useful for identifying questions affecting
specific portions of the regulations.  For example,  under the heading "40 CFR Part 248-250,
252,253 - Guidelines for Federal Procurement" is a question entitled "Procurement
Requirements Applicable to Government Agencies" and a Federal Register notice from
October 22,1993, regarding procurement guidelines and guiding principles.

Similarly,  the third index organizes the questions by statutory citation.  For example, the
question entitled "Maximum Quantity Reporting of §313 Establishments" 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.
