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.

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.

RCRA 110,113 (59%) ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) Land Disposal Restrictions Key Words: Case-by-case extension; LDR;soil;toxicity characteristic "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). (January 1993 Monthly Hotline Report) Subtitle D Key Words: MSWLF; Subtitle D "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 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "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. ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Effective Date Delayed for Certain MSWLFs" (cont'd) The above summary represents an overview of the new federal compliance 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) Key Words: Federal agency; procurement guidelines; recycling; Subtitle D "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 and purchase $10,000 or more worth of a product designated in a EPA guideline during the current fiscal year, or purchased $10,000 or more worth of a designated item or functionally equivalent items during the preceding fiscal year, are required to comply with RCRA §6002. (August 1993 Monthly Hotline Report) TSDFs Key Words: Closure; interim status; TSDF "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, ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Closure Timetable Following Termination of Interim Status" (cont'd) 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)). (June 1993 Monthly Hotline Report) Key Words: Containment building; generator accumulation; TSDF "Containment Buildings as Independent Hazardous Waste Management Units" 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? ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Containment Buildings as Independent Hazardous Waste Management Units" (cont'd) 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 generator accumulating hazardous wastes solely in containers, in tanks, or on drip pads in accordance with 40 CFR §§262.34(a)(l)(i), (ii), or (iii) is not required to comply with the standards for containment buildings specified in §262.34(a)(l)(iv). (November 1993 Monthly Hotline Report) Key Words: Containment building; interim status; permit; TSDF "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 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Containment Buildings at Permitted and Interim Status Facilities" (cont'd) 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, 10 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Containment Buildings at Permitted and Interim Status Facilities" (cont'd) §§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 Report) Key Words: Groundwater; MCLs; permit; TSDF "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? 11 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) Used Oil "The Use of Maximum Contaminant Levels (MCLs) In Groundwater Monitoring" (cont'd) ANSWER: Yes, MCLs, promulgated under the SDWA, that have not been codified in Table 1 of §264.94(a)(2) may be used as concentration limits when establishing the GWPS in the facility's permit by designating them as ACLs under §264.94(a)(3). EPA encourages the use of these MCLs in developing ACLs under §264.94(a)(3). (May 1993 Monthly Hotline Report) Key Words: Hazardous waste definition; ignitability characteristic; mixture; toxicity characteristic; used oil "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 12 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Mixtures of Used Oil and Characteristic Hazardous Waste" (cont'd) 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).

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 Hotline Report) Waste Identification Key Words: Closed-bop; exclusion; hazardous waste definition; recycling; tank "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)? 13 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "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 Report) Key Words: Exemption; hazardous waste definition; natural gas condensate "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 14 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Natural Gas Condensate: Regulatory Status" (cont'd) 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) Key Words: Commercial chemical product; hazardous waste definition; P081 "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 15 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Nitroglycerine Pills as Commercial Chemical Products" (cont'd) ingredient that will cause a waste to fall within, or be excluded from, the listing. In this example, the pills constitute a formulation containing 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. (September 1993 Monthly Hotline Report) Key Words: Hazardous waste definition; sample; testing; toxicity characteristic "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. Outlined in section 8.4 of Method 1311(Part 261, Appendix II), maximum 16 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Sample Holding Times and Validity of Analytical Results" (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 Subtitle C.

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 chlorophenoxy compounds. The listing description of F027 includes discarded unused formulations containing compounds derived from tri-, 17 ------- RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) "Unused Formulations of Agent Orange" (cont'd) tetra-, or pentachlorophenol. Since Agent Orange contains a compound derived from the synthesis of trichlorophenol (i.e., 2,4,5-T), it is appropriately classified as F027 upon disposal. (June 1993 Monthly Hotline Report) Key Words: F005; hazardous waste definition; K086; solvent "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.)

Financial responsibility; local government; UST Regulated Substances Key Words: Mineral spirits; regulated substance: UST "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.

ANSWER: Part 280 does apply to underground tanks containing mineral spirits. The underground tank regulations apply to any UST holding 19 ------- UNDERGROUND STORAGE TANKS (UST) "Mineral Spirits as a Regulated Substance Under the UST Regulations" (cont'd) regulated substances. The term "regulated substance" is defined as any CERCLA hazardous substance (except RCRA hazardous wastes) and 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 petroleum USTs under Part 280. (December 1993 Monthly Hotline Report) 20 ------- SUPERFUND (SF) Cleanup Requirements Key Words: DNAPL; groundwater; remediation; solvent "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 ------- SUPERFUND (SF) "Dense Nonaqueous Phase Liquid (DNAPL) Contamination at Superfund Sites" (cont'd) 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 22 ------- SUPERFUND (SF) "Dense Nonaqueous Phase Liquid (DNAPL) Contamination at Superfund Sites" (cont'd) an engineering perspective, consistent with EPA guidance (OSWER Directive 9234.2-25).

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 ------- SUPERFUND (SF) "Land Disposal Restrictions as ARARs at Superfund Sites" (cont'd) AOC, or when wastes are excavated from an AOC, placed in a separate hazardous waste management unit such as an incinerator or tank that is 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 Hotline Report) Key Words: Cooperative agreement; NCP; remediation; state program "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 24 ------- SUPERFUND (SF) "State Authority in Selecting the Remedy at State-lead Superfund Sites" (cont'd) National Contingency Plan (NCP), "EPA believes that, although Congress contemplated an increased role for states in the remedial process through the enactment of CERCLA §121(f), it should retain primary responsibility 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 Hotline Report) Financial Key Words: Liability; PRP; settlements "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 ------- SUPERFUND (SF) "De Micromis Superfund Settlements" (cont'd) funds for site cleanup while eliminating further negotiation and litigation 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). 26 ------- SUPERFUND (SF) "De Micromis Superfund Settlements" (cont'd) 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. (September 1993 Monthly Hotline Report) Key Words: Exemption; liability; recycling; used oil "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 ------- SUPERFUND (SF) "Liability Exemption Under CERCLA for Service Station Dealers 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.

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 ------- SUPERFUND (SF) "Accelerating Superfund Cleanups" (cont'd) 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, Numbers 1-5, December 1992), as well as Guidance on Implementation of the Superfund Accelerated Cleanup Model (SACM) under CERCLA and the NCP (publication number 9203.1-03; July 7,1992). EPA also publishes intermittent bulletins on the progress of pilot projects involving presumptive remedies under publication number 9203.1-021 (Volume 1, Numbers 1-3, April through August 1992). These guidance documents are available from the National Technical Information Service (NTIS).

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).

(March 1993 Monthly Hotline Report) 31 ------- EMERGENCY PLANNING AND COMMUNITY RIGHT-TO-KNOW ACT (EPCRA) Emergency Planning and Release Notification Key Words: CAS number; commercial chemical product; hazardous chemical; hazardous substance; toxic chemical "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 ------- EMERGENCY PLANNING ACT (EPCRA) AND COMMUNITY RIGHT-TO-KNOW "Chemicals Listed with Multiple Chemical Abstract Service Numbers" (cont'd) allowing the chemical to be located with any assigned number. The misassigned numbers are deleted as registry numbers, but remain on file for 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 registry file system to display the name, synonyms, and characteristics 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) Key Words: Emergency planning; facility emergency coordinator; LEPC "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 34 ------- EMERGENCY PLANNING AND COMMUNITY RIGHT-TO-KNOW ACT (EPCRA) "Designation of Facility Emergency Coordinator" (cont'd) the SERC, the statute provided a grace period for naming the emergency coordinator until September 17,1987, or 30 days after the LEPC was formed. There is no longer any reason for this grace period and it is no longer applicable. At this time, the period for appointing the LEPCs has passed. Since the emergency planning notification for newly regulated facilities is to be provided to the SERC and the LEPC, the name of the facility coordinator should also be provided at the time the facility provides its emergency planning notification under §302(c). (July 1993 Monthly Hotline Report) Hazardous Chemical Inventory Reporting "Polymer Pellet Reporting Under §§311 and 312" 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) Key Words: Exclusion; hazardous chemical; manufactured solid; polymer pellet; Tier l/ll 35 ------- EMERGENCY PLANNING AND COMMUNITY RIGHT-TO-KNOW ACT (EPCRA) Key Words: Mixture; proprietary compound: Tier l/ll "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 36 ------- EMERGENCY PLANNING AND COMMUNITY RIGHT-TO-KNOW ACT (EPCRA) "Proprietary Compounds and EPCRA §§311/312 Reporting" (cont'd) there is no information reasonably available to the owner or operator to make this determination, the regulations do not require reporting the 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. (December 1993 Monthly Hotline Report) Key Words: Exemption; manufactured solid; sheet metal; Tier l/ll "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 ------- EMERGENCY PLANNING AND COMMUNITY RIGHT-TO-KNOW ACT (EPCRA) "Sheet Metal Reporting and the Exemption for Manufactured Solids Under §§311/312" (cont'd) equal to 500 pounds or the threshold planning quantity, whichever is lower. The entire weight of the items to be altered (the non-exempt items) is counted toward the threshold, not just the weight of the hazardous chemical in the section of the item on which work is done. The weight of the entire piece of sheet metal is used because the sheet is the manufactured item; the exemption cannot apply to a portion of a manufactured item.

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.

If a facility is reporting by establishment, should the quantity reported in Section 4.1 represent the maximum quantity at the establishment or the maximum quantity for the entire facility? ANSWER: If a Form R is being submitted for "part of a facility" (i.e., an establishment or group of establishments), the range code selected for the maximum amount of a toxic chemical on-site should be reflective of the establishment or group of establishments, not of the entire facility. (April 1993 Monthly Hotline Report) Key Words: Form R; personal use exemption: TRI "Personal Use Exemption and Refrigerants" QUESTION: Would toxic chemicals used as refrigerants in a facility's air conditioning unit be exempt from EPCRA §313 reporting under the personal use exemption (40 CFR §372.38(c)(3))? ANSWER: Yes, if the air conditioning unit is used solely for the purpose of maintaining employee comfort, the toxic chemicals used in the unit would be exempt from EPCRA §313 reporting under the personal use exemption. If, however, the air conditioning unit is integral to the facility's operation or activity (e.g., maintaining constant temperature and humidity for machinery or cold storage rooms), then the toxic chemicals used in the unit would not be exempted from EPCRA §313 reporting.

ANSWER: Cobalt-60 with CAS number 10198-40-0 is not on the list of toxic chemicals under EPCRA §313. The listed toxic chemical is cobalt with CAS number 7440-48-4. As such, Cobalt-60 is not reportable under EPCRA §313.

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 Hotline Report) Key Words: Form R; pollution prevention; release; TRI "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.

The requirements for the petition process that will be used to add or delete chemicals from the final list is also included in this proposed rule. Comments must be submitted by March 22, 1993. Citation: October 20,1993 (58 £E 54190) "Risk Management Programs for Chemical Accidental Release Prevention" SUMMARY: EPA published a proposed rule under the Clean Air Act provisions for accidental release prevention. The rule proposes regulations that would require development and implementation of risk management programs at facilities that manufacture, process, use, store, or otherwise handle regulated substances in quantities that exceed specified thresholds. Comments must be submitted on or before February 16,1994. The first in a series of public meetings on this rule will be held on November 30,1993, from 9 am to 5 pm, at Temple Mica, 600 M Street, SW, Washington, DC. A notice will be published in the Federal Register with more information on additional public hearings. 64 ------- EMERGENCY PLANNING AND COMMUNITY RIGHT-TO- KNOW ACT (EPCRA) ACCIDENTAL RELEASE PREVENTION PROGRAM (CAA §112(r)) (cont'd) Final Rules Citation: November 2,1993 (58 EB 58548) "Hydrogen Fluoride Study; Report to Congress" SUMMARY: EPA announced the availability of the study of commercial and industrial uses of hydrofluoric acid and the hazards it may present to human health and the environment, as mandated by CAA §112(n)(6). Comments must be submitted on or before December 15,1993. 65 ------- 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. 67 ------- KEY WORD INDEX ARAR "Land Disposal Restrictions as ARARs at Superfund Sites" p. 23 (S) Boilers and industrial furnaces (BIFs) 58 FR 59598;
