02/17/2012SCOPE OF HAZARDOUS WASTE LISTING P046 (PHENTERMINE)Memo
 Description: The scope of the P046 listing does not include phentermine salts (SEE ALSO: RO 14778).
 
08/23/2010REGULATION OF UNUSED DERMAL NICOTINE PATCHESMemo
 Description: Unused dermal patches containing nicotine would be regulated as a listed hazardous waste when disposed. Nicotine in finished dosage forms, such as tablets or capsules, is regulated because it is a commercial chemical product formulation containing nicotine as the sole active ingredient. EPA views transdermal patches as an analogous dosage form. However, after the patch has been applied and removed, it has been used for its intended purpose and therefore would not be listed hazardous waste when discarded. EPA does not view dermal patches to be “manufactured articles”. This letter supersedes an earlier response that was included in a report for the RCRA, Superfund & EPCRA Hotline, RCRA/UST, Superfund and EPCRA Monthly Hotline Report, April 1995 (RO 13741, page 1).
 
05/14/2009DETERMINATION ON ZIRCONIUM OXIDE COATING PROCESS AS ALUMINUM AND THE F019 LISTINGMemo
 Description: Chemical conversion coating refers to processes used to protect metals from corrosion and to prepare for painting or other surface treatment. Specifically, four operations are within the scope of chemical conversion coating in the F019 listing - coloring, chromating, phosphating, and immersion plating. Zirconium oxide processes do not fit within these categories. The process does not use chromium or phosphate, the aluminum is not converted to an oxide but rather is coated with precipitated zirconium oxide, and does not deposit a layer of metal. While the zirconium oxide process is not covered by the F019 listing, it is possible for the resulting waste to be characteristic.
 
05/01/2008Environmental Fact Sheet: Listing Amendment for F019 Wastewater Treatment SludgesPublication
 Description: This fact sheet discusses a final rule that amended the F019 hazardous waste listing to facilitate the use of aluminum in automobiles, light trucks, and utility vehicles. Using aluminum parts produces lighter vehicles capable of increased gas mileage and decreased exhaust air emissions, including a reduction in the emission of greenhouse gases.
 
03/01/2008Hazardous Waste Listings: A User-Friendly Reference Document (Draft)Publication
 Description: This web-based document serves as a user-friendly reference to assist EPA and state staff, industrial facilities generating and managing hazardous wastes, and the general public in locating and understanding the hazardous waste listing regulations, located in 40 CFR Part 261.
 
10/15/2007SCOPE OF HAZARDOUS WASTE LISTING P042 (EPINEPHRINE)Memo
 Description: The scope of the P042 listing does not include epinephrine salts (SEE ALSO: RO 14831).
 
08/23/2007RECLAMATION OF MATERIAL RECOVERED FROM CRUDE OIL STORAGE TANKSMemo
 Description: Crude oil tank sediment from petroleum refining operations is listed hazardous waste K169. If the tank is located at or affiliated with a petroleum refinery, and the tank materials are reclaimed on-site at the petroleum refinery, the generated residuals would meet the K169 listing. Crude oil tank materials sent for legitimate reclamation would not be a solid waste. Residuals generated from off-site reclamation would represent a new point of generation, would not meet the K169 listing, and would only need to be assessed for hazardous waste characteristics. No listings apply to discarded tank sediments for crude oil storage not located or affiliated with a petroleum refinery.
 
05/18/2007REGULATORY STATUS OF WASTEWATER TREATMENT SLUDGES FROM ALUMINUM AND COPPER FINISHINGMemo
 Description: Copper etching/bright dipping is within the scope of the F006 listing. Descaling by an acidic solution removes metal from the surface and is therefore essentially chemical etching. Bright dipping is a chemical etching process (SEE ALSO: Memorandum, Straus to Sauer; January 27, 1987 (RO 11214)). Bright dipping is defined as a “specialized form of etching that is used to remove oxide and tarnish from ferrous and nonferrous materials”.
 
01/01/2007Environmental Fact Sheet: Proposed Listing Exemption for F019 Wastewater Treatment SludgesPublication
 Description: This fact sheet discusses the proposed listing exemption for F019 wastewater treatment sludges. EPA is proposing to amend the F019 hazardous waste listing in order to encourage the use of aluminum in motor vehicles, which will decrease exhaust air emissions and increase gas mileage.
 
02/01/2005Environmental Fact Sheet: Waste from the Production of Dyes and Pigments Listed as HazardousPublication
 Description: This fact sheet discusses the listing of waste from the production of certain dyes, pigments, and food, drug, and cosmetic colorants (FD&C) as EPA hazardous waste K181. EPA is using a flexible regulatory approach that focuses on total quantities of chemical constituents of concern that present the greatest risk. Specifically, the K181 listing focuses on seven hazardous constituents: aniline, o-anisidine, 4-chloroaniline, p-cresidine, 1,2-phenylenediamine, 1,3-phenylenediamine, and 2,4-dimethylaniline.
 
04/12/2004POLICY ON THE MANAGEMENT OF RINSATE FROM EMPTY CONTAINERSMemo
 Description: Even though rinse water from an “empty” container may be non-hazardous, 261.7 does not exempt rinse water because rinse water is not a waste “remaining in” an “empty” container. When residue is removed from an empty container the residue is subject to full regulation under Subtitle C if the removal or subsequent management of it generates a new hazardous waste exhibiting any characteristics identified in Part 261, Subpart C. Rinsing an “empty” container with an agent containing solvent that would be listed when discarded would cause rinsate from an “empty” container to be listed due to the nature of the rinsing agent, not the nature of the waste being rinsed from the “empty” container.
 
02/18/2004APPLICATION OF P AND U WASTE CODES TO FERTILIZERS MIXED WITH INSECTICIDES OR HERBICIDESMemo
 Description: Listings in 261.33(e) or 261.33(f) do not include chemical mixtures where the listed chemical is not the sole active ingredient, regardless of whether only one or more active ingredients are present. Note that “sole active ingredient” means the active ingredient is the only chemically active component that performs the functions of the product. When a formulated product has more than one chemical or compound as an active ingredient, the presence of a P or U chemical substance in the formulation does not render the product, when discarded, a P- or U-listed hazardous waste. Such products still need to be evaluated to determine if they exhibit any hazardous waste characteristics.
 
11/01/2003EPA Proposed Hazardous Waste Listing Determination for Dyes and Pigments Production WastesPublication
 Description: This fact sheet discusses EPA's proposed listing of nonwastewaters from the production of certain dyes, pigments, and food, drug and cosmetic (FD&C) colorants as hazardous wastes under RCRA.
 
05/16/2002REGULATORY STATUS OF VANADIUM-CONTAINING WASTE (SPENT STRETFORD SOLUTION)Memo
 Description: The consent decree in EDF v. Browner, Civ. No. 89-0598 (D.D.C.), required EPA to decide whether or not to list several categories of petroleum refining wastes and to prepare a report on other waste categories. EPA determined that sludges from the Stretford process (which contain vanadium salts), catalysts from sulfur complex and H2S facilities, and vanadium-containing Stretford or Beavon-Stretford solutions do not require listing determinations (SEE ALSO: Listing Background Document for 1992-1996 Petroleum Refining Listing Determination, Study of Selected Petroleum Refining Residuals, and 63 FR 42110; 8/6/98). Hazardous waste listing determinations are wastestream-specific, not constituent-specific. Vanadium does not present sufficient risk to provide a basis for listing. EPA is deferring the use of the persistence, bioaccumulative, and toxic (PBT) criteria for metals in its waste minimization program, since it is working to develop an Agency-wide approach. The Science Advisory Board (SAB) will review the 3MRA model, which estimates the chemical release, fate, exposure and resulting risks to human health and the environment (SEE ALSO: 64 FR 63382; 11/19/99).
 
05/06/2002REGULATORY STATUS OF SOLVENT-CONTAMINATED SHOP TOWELSMemo
 Description: EPA has not determined what regulatory action is appropriate for solvent-contaminated shop towels. EPA may provide an exclusion from the definition of solid waste for these items. States have policies for contaminated wipes, but the regulations differ from state to state. Generators have petitioned EPA for federal regulations to promote regulatory consistency. EPA is working with stakeholders to develop a proposal that ensures environmentally sound management, is cost-effective, and encourages source reduction and recycling of the hazardous solvents.
 
05/01/2002REGULATORY STATUS OF SOLVENT-CONTAMINATED SHOP TOWELSMemo
 Description: EPA may provide an exclusion from the definition of solid waste for solvent-contaminated shop towels. States have policies for contaminated wipes, but regulations differ from state to state. Generators have petitioned EPA for federal regulations to promote regulatory consistency. EPA is working with stakeholders to develop a proposal, which ensures that solvent-contaminated shop towels are managed in an environmentally sound manner at the lowest possible cost to the regulated community.
 
12/11/2001CLARIFICATION OF THE NEW MIXTURE AND DERIVED-FROM RULES FOR F003Memo
 Description: Section 261.3(g)(1) generally exempts hazardous waste originally listed as F003 if it no longer exhibits the characteristic of ignitability. Mixtures of solid waste and F003 wastes and wastes derived-from F003 are no longer hazardous and the F003 code is removed if the subsequent wastes no longer exhibit the characteristic of ignitability. F003 land disposal restrictions (LDR) requirements are still applicable to the exempted waste if it exhibited the characteristic of ignitability at the point of generation, regardless of whether it is ignitable at the point of land disposal. If a waste that meets the F003 listing contains 10% or more of the other F-listed solvents (F001, F002, F004 and/or F005) but is not ignitable or if a waste that meets the F003 listing is mixed with another listed waste and is not ignitable, then the F003 waste code would be dropped, all other waste codes would be retained.
 
11/01/2000Environmental Fact Sheet: EPA Promulgates Listing Determination for Certain Wastes from the Production of Chlorinated Aliphatics Publication
 Description: Presents background information about chlorinated aliphatics waste streams, and announces the promulgated listing.
 
09/01/2000Environmental Fact Sheet: Three Inorganic Chemicals Now Listed as Hazardous WastePublication
 Description: EPA added three wastes, K176-178, from inorganic chemical manufacturing processes to the list of hazardous waste. EPA determined that regulating these chemical wastes will protect human health and the environment by eliminating potential pathways of exposure.
 
06/01/2000REQUEST FOR CLARIFICATION OF ISSUES RAISED BY EPA'S NOVEMBER 29, 1999 MEMO ON THE "PETROLEUM REFINERY RESIDUAL LISTINGS/ SOLID WASTE DEFINITION EXCLUSION RULE" (63 FR 42110, AUGUST 6, 1998)Memo
 Description: Spent catalysts from petroleum hydroprocessors performing treating function are listed hazardous waste (K171). EPA does not consider spent catalysts from petroleum hydroprocessing reactors to be a listed hazardous waste solely because some incidental and minimal amount of hydrotreatment occurs in hydrocracking reactors. EPA reserves right to conduct listing determination on spent hydrocracking catalyst in the future. Spent hydrocracking catalyst are subject to hazardous waste characteristic determination (SEE ALSO: 66 FR 35379; 7/5/01).
 
06/01/2000REQUEST FOR CLARIFICATION, SPENT CATALYSTS FROM MOTIVA ENTERPRISES LLC, CONVENT REFINERY H-OIL UNITMemo
 Description: Spent catalysts from dual purpose petroleum hydroprocessor performing substantial hydrotreating function are listed hazardous wastes (K171) (SEE ALSO: RPC# 11/29/99-01).
 
06/01/2000SPENT CATALYSTS FROM PETROLEUM REFINING DUAL PROCESS REACTORSMemo
 Description: Spent catalysts from dual purpose petroleum hydroprocessor performing substantial hydrotreating function are listed hazardous wastes (K171 or K172). Listing does not apply to spent catalysts solely because some incidental and minimal amount of hydrotreatment occurs in unit. Spent hydrocracking catalyst are subject to hazardous waste characteristic determination (SEE ALSO: RPC# 11/29/99-01).
 
05/12/2000CLARIFICATION OF BEVILL STATUS OF ELECTRIC ARC FURNACE SLAGSMemo
 Description: EPA established criteria to determine if a process was defined as mineral processing on September 1, 1989 (54 FR 36619). Only facilities processing less than 50 percent scrap are eligible for Bevill exclusion. Most steel making “mini mills” using electric arc furnaces are not eligible for Bevill exclusion. Flue dust from steel making electric arc furnaces are listed hazardous wastes.
 
11/29/1999SPENT CATALYSTS FROM PETROLEUM REFINING DUAL PROCESS UNITSMemo
 Description: Spent catalysts from petroleum hydroprocessors performing hydrotreating or hydrorefining operations are captured by the K171 and K172 listings, regardless of whether hydrocracking also occurs in a dual purpose unit. EPA differentiates between hydrocracking and the other two petroleum hydroprocessing operations by relying upon the definitions of these processes in DOE’s Petroleum Supply Annual (PSA) (SEE ALSO: 66 FR 35379; 7/5/01).
 
10/01/1998CONTAMINATED ELECTROPLATING RINSEWATERSQuestion & Answer
 Description: Rinsewaters contaminated with plating bath solutions or stripping and cleaning bath solutions are not within the scope of the F007 or F009 hazardous waste listings. Trace amounts of plating and stripping solutions carried over to rinse tanks are not considered solid or hazardous wastes mixing with another solid waste, as these materials are in use and not wastes until spent and removed from the process. Spent rinsewaters removed from the process are regulated if they exhibit a characteristic or become mixed with a listed hazardous waste.
 
07/15/1998SPENT METHYL BROMIDE ACTIVATED CARBON IS NOT U029Memo
 Description: Spent activated carbon used to capture methyl bromide that has been used for its intended purpose is not a listed U029 hazardous waste. The P and U lists apply to unused commercial chemical products. The spent carbon may still exhibit a characteristic of hazardous waste.
 
06/01/1998APPLICABILITY OF F009 LISTING TO CLEANING TANK SLUDGEQuestion & Answer
 Description: Contaminants that settle out from electroplating cleaning bath solutions and form a sludge on the bottom of the cleaning tank are an F009 listed waste when removed from the cleaning tank. The settled materials forming the sludge are part of the spent stripping and cleaning bath solutions, and therefore, are an F009 waste.
 
06/01/1998Petroleum Refining Waste Listing Determination Notice of Data Availability (NODA) Response to Comment Document; Part IPublication
 Description: This document responds to public comments relevant to several Federal Register notices announcing data availability for the proposed listing determination for petroleum refining process wastes.
 
06/01/1998Petroleum Refining Waste Listing Determination Notice of Data Availability (NODA) Response to Comment Document; Part IIPublication
 Description: This document responds to public comments relevant to several Federal Register notices announcing data availability for the proposed listing determination for petroleum refining process wastes.

 Description: This document responds to public comments received on EPA's proposal to add several petroleum refining wastes to the RCRA list of regulated hazardous waste and not to list other petroleum refining operation wastes. Specifically, this part responds to public comments relevant to residual specific issues, such as sediments, sludges, and catalysts.
 
06/01/1998Petroleum Refining Waste Listing Determination Proposed Rule Response to Comment Document; Part IVPublication
 Description: This document responds to public comments received on EPA's proposal to add several petroleum refining wastes to the RCRA list of regulated hazardous waste and not to list other petroleum refining operation wastes. Specifically, this part responds to public comments relating to options for conditional exemptions, idled units, third party regeneration of spent catalysts, headworks exemption, waste minimization, LDR, LDR capacity determinations, environmental justice, CERCLA designation, economic alalysis and miscellaneous topics.
 
06/01/1998Petroleum Refining Waste Listing Determination: Additional Groundwater Pathway Risk Analysis; Supplemental Background DocumentPublication
 Description: This document describes the groundwater pathway analyses performed to support the petroleum refining listing determination. The analyses were designed to determine the potential exposure, via the groundwater pathway, to human receptors from petroleum refining wastes, being managed and/or disposed in land management units. The exposure is expressed in terms of the contaminant concentration at a groundwater extraction well located down-gradient from the wastemanagement unit.
 
05/19/1998PROVISIONAL ELIMINATION OF F032 WASTE CODEMemo
 Description: A provisional elimination of the F032 waste code for decontaminated equipment does not apply to contaminated soils. The original provision (55 FR 50450; 12/6/90) required new process wastes not to show any level of dioxin. The amendment (57 FR 61492; 12/24/92) specifies that facilities that switch to an alternative chemical (other than chlorophenol) are not required to identify their wastes as F032 as long as they continue to manage the waste as F034 or F035. Storage yard soils contaminated with infrequent or incidental drippage (kickback) would not carry a listing if wood preserving plants develop and implement a contingency plan for emergency response to drippage.
 
01/06/1998CLASSIFICATION OF SPILLED TOLUENE AS U220 HAZARDOUS WASTEMemo
 Description: Off-specification commercial chemical product (CCP) is an unused material that would have been a CCP if it met specifications. EPA has not set exact concentrations for a CCP to be considered off-specification. A material can be off-specification CCP if it is contaminated without being used for its intended purpose (e.g., during storage). If a material is contaminated via normal use, it would be a spent material. A spent material can regain its unused CCP status if the material is reclaimed and requires no additional processing before it can be used beneficially. Used toluene spilled from a storage tank may meet F005 listing or may exhibit a characteristic (such as ignitability).
 
10/01/1997REEXAMINATION OF PROPOSED EXCLUSION FOR OIL-BEARING RESIDUALSMemo
 Description: EPA proposed to broaden the recovered oil exclusion to include all oil-bearing hazardous wastes inserted into the refining process (60 FR 57747; 11/20/95). EPA did not intend to create a loophole from hazardous waste status for residual materials left over from the recycling process (e.g., residuals generated from deoiling excluded sludges that are not themselves reinserted into the refinery) (SEE ALSO: 63 FR 42110; 8/6/98, and new F037 listing).
 
09/03/1997HAZARDOUS WASTE LISTING DETERMINATION FOR ORGANOBROMINE PRODUCTION WASTESMemo
 Description: EPA continues to believe that solids and filter cartridges from the production of 2,4,6-tribromophenol warrant listing. In response to comments and information received since the organobromines proposal (59 FR 24530; 5/11/94) (SEE ALSO: 63 FR 24596; 5/4/98), EPA reexamined the listing decision. This letter provides notice and explanation of EPA's further evaluation of the listing. decision. EPA will accept comment on the additional information up to 30 days from the date of letter issuance (SUPERSEDED: Organobromine listings vacated; see 65 FR 14472; 3/17/00) .
 
06/01/1997USE AS INGREDIENT NOT WITHIN SOLVENT LISTINGQuestion & Answer
 Description: The use of solvent as an ingredient is not covered by the spent solvent listings. Unused product being disposed would not carry an F listing if the unused solvent had been added as an ingredient. Unused product may be P or U listed when disposed if the solvent served as the sole active ingredient in the product.
 
05/23/1997REQUEST FOR OPINION REGARDING CARBAMATE WASTE GENERATED BY CYTEC INDUSTRIES INC.Memo
 Description: The K156 listing (organic wastes from the production of carbamates and carbamoyl oximes) includes wastes from the production of methyl carbamate. Carbamate is a salt or ester of carbamic acid and methyl carbamate is the simplest ester of carbamic acid. A generator may petition for a delisting if the wastestream does not contain hazardous constituents that are the basis for listing K156. Industry may challenge a final rule during the 90 day period after the rule is promulgated (RCRA 7006(a)(1)).
 
05/19/1997RULES FOR DISPOSAL OF DISCARDED CONCRETEMemo
 Description: Concrete has not been identified by EPA as listed hazardous waste. Common concrete is not likely to exhibit any of the characteristics of hazardous waste. Authorized states can establish more stringent requirements and may have their own rules regarding nonhazardous waste or debris.
 
04/07/1997ISSUANCE OF FINAL HWIR-MEDIA RULEMemo
 Description: EPA has reached agreement with Edison Electric Institute to amend their consent decree regarding Hazardous Waste Identification Rules (HWIR). The deadline for promulgation of HWIR-waste is now April 30, 2001 (SEE ALSO: 64 FR 63382; 11/19/99). The agreement also commits EPA to issue a final rule for HWIR-Media by June 30, 1998 (HWIR-Media finalized 63 FR 65873; 11/30/98). EPA’s policy of treating violations of land disposal storage restrictions (Section 3004(j)) with reduced, federal, enforcement priority for small volumes of mixed waste, is effective through April 1998. Prior to expiration of this policy EPA will determine whether an extension is warranted. The policy does not apply to any mixed waste for which treatment is currently available, or becomes available during the term of the policy (SEE ALSO: 64 FR 63464; 11/19/99).
 
04/07/1997REPROPOSAL OF HWIR WASTE RULE AND COMMERCIAL MIXED WASTESMemo
 Description: EPA will sign notice of proposed rulemaking by October 31, 1999, for the Hazardous Waste Identification Rule for Waste (HWIR-waste) (SEE ALSO: 64 FR 63382; 11/19/99). HWIR-waste will seek comment on, among other things, an exemption from hazardous waste disposal regulation, and other regulatory relief as appropriate, for commercial mixed waste (SEE ALSO: 64 FR 63464; 11/19/99). EPA plans to finalize a decision by April 30, 2001. EPA will recommend suspension of Part B permit collection for plants subject to the Atomic Energy Act (AEA) which need the permit solely for on-site storage of mixed waste. Such plants will remain subject to interim status standards. EPA may need to extend the storage prohibition enforcement policy for mixed waste.
 
10/30/1996INCLUSION OF ADDITIONAL CHEMICAL REAGENT INTO EXISTING K062 EXEMPTIONMemo
 Description: The Section 261.3(c)(2)(ii)(A) exclusion applies only to spent pickle liquor sludge (K062) stabilized with lime. The exclusion does not apply if other treatment agents (e.g., magnesium hydroxide) are used. Expansion of the exclusion is not a priority for OSW.
 
03/13/1996USE OF THE AREA OF CONTAMINATION (AOC) CONCEPT DURING RCRA CLEANUPSMemo
 Description: Addresses the use of the area of contamination (AOC) concept during RCRA cleanups, and the relationship of an AOC to a corrective action management unit (CAMU). An AOC refers to a discrete area of generally dispersed contamination. Discusses the regulatory status of the CAMU rule in relation to the Hazardous Waste Identification Rule (HWIR)-Media and litigation (SEE ALSO: 63 FR 65873; 11/30/98). Also discusses the definition of placement.
 
10/18/1995CONCERN REGARDING EPA'S PLANS TO ""DISALLOW CONTINUED USE OF THE CORRECTIVE ACTION MANAGEMENT UNIT (CAMU) PROVISION""Memo
 Description: CAMUs should be used only if the area of contamination (AOC ) concept cannot be used. The AOC concept is independent of the CAMU rule (SEE ALSO: Hazardous Waste Identification Rule for Media (HWIR-Media), 63 FR 65873; 11/30/98).
 
10/01/1995Environmental Fact Sheet: EPA Will List 3 of 14 Residuals from Petroleum Refining ProcessesPublication
 Description: This fact sheet outlines the requirement for EPA to make a listing determination on 14 specified wastes from petroleum refining operations. The results of EPA's initial data collection effort concluded with a proposal to identify 3 of the 14 residuals as listed hazardous wastes.
 
01/01/1995Environmental Fact Sheet: Regulatory Determination Issued for Cement Kiln DustPublication
 Description: This fact sheet discusses the need for stricter management controls for cement kiln dust (CKD) and the Agency's plan to develop specific controls that prevent damage to ground and potable waste and reduce health risks associated with breathing and ingesting dust from cement kilns.
 
11/05/1993ADDITIONAL ANALYTES FOR HWIR TARGET ANALYTE LIST IN WASTEWATERMemo
 Description: Discusses the review of six potential Hazardous Waste Identification Rule (HWIR) analytes for their analytical suitability and potential to be found in wastewaters (SEE ALSO: 60 FR 66344; December 21, 1985).
 
08/15/1992Environmental Fact Sheet: Management Standards Issued to Control Potential Risks from Recycled Used Oil - No Hazardous Waste ListingPublication
 Description: This fact sheet introduces EPA management standards for all segments of the used oil recycling system. The standards apply simple controls to generators of used oil and more stringent controls to processors, refiners, and transporters of used oil. The controls, found at 40 CFR 279, diminish potential risks and make it unnecessary to list recycled used oil as hazardous waste.
 
06/15/1992Environmental Fact Sheet: Treatment Standards Finalized for 20 Newly Listed Hazardous Wastes and Hazardous DebrisPublication
 Description: This fact sheet announces land disposal restriction (LDR) rules for 20 newly listed hazardous wastes. Wastes include recent petroleum refining wastes (F037 and F038), wastes from unsymmetrical dimethylhydrazine (K107-K110), wastes from dinitrotoluene and toluenediamine (K111 and K112), wastes from ethylene dibromide (K117, K118, and K136), wastes from ethylenebisdithiocarbamic acid (K123-K126), wastes from methyl bromide (K131 and K132), and additional organic U wastes (U328, U353, and U359). The fact also describes additional components of the LDR rules, including regulations for hazardous debris and containment buildings.
 
05/15/1992Environmental Fact Sheet: No Hazardous Waste Listing for Used Oil That Is Being DisposedPublication
 Description: This fact sheet discusses a rulemaking that announces the determination that it is unnecessary to list used oil being disposed of as hazardous waste. This rule finalizes the September 1991 Supplemental Proposal to reevaluate the 1986 decision not to list used oil as hazardous waste.
 
06/07/1991SCOPE OF THE F006 LISTINGMemo
 Description: F006 wastewater treatment sludges include sludges from any type of treatment (e.g., chemical, biological, or simple settling). The domestic sewage exclusion does not extend to private or other non-municipal treatment works (SEE ALSO: FFCA added federally owned treatment works (FOTW) to the exclusion). A mixture of sewage and other wastes en route to a non-municipal treatment works does not cease to be a solid waste. The waste’s identity relevant to hazardous waste listings (i.e., F006) continues throughout the treatment works. The mixture rule exemption for laboratory wastes in 261.3(a)(2)(iv)(E) applies to laboratories discharging diverse, diluted amounts of listed toxic wastes. An electroplating shop located within a larger research and development (R&D) facility is not a laboratory, nor does it generate dilute wastewaters characteristic of an R&D laboratory.
 
06/01/1989APPENDIX VIII AND APPENDIX IXQuestion & Answer
 Description: Explains the differences between Part 261 Appendix VIII and Part 264 Appendix IX. EPA uses 261 Appendix VIII in listing hazardous wastes, but it should not be used by generators in waste identification. 264 Appendix IX is used only for groundwater monitoring at permitted facilities.
 
09/09/1988LD50 AS CRITERIA FOR LISTING HAZARDOUS WASTEMemo
 Description: The LD50 level is used to designate acutely hazardous wastes. The LD50 level is used unchanged, i.e., no extrapolation to humans.
 
07/24/1987WASTES GENERATED BY COKE AND COAL TAR PLANTSMemo
 Description: There are no solids or organics content or % water limits for “primarily aqueous” wastewater streams. Addresses the industrial wastewater discharge exclusion (261.4(b)(2)) and “commonly defined by the industry as wastewaters,” and provides examples. The wastewater treatment unit (WWTU) exemption is not for surface impoundments. Discusses “trigger” levels for possible coke by-product K-listings. The listing will be based on 261.11 criteria, which are based on potential hazards and mismanagement, but are not based directly on waste minimization.
 
05/09/1986HEALTH ASSESSMENT INFORMATION IN LISTING DECISIONSMemo
 Description: EPA uses health assessment information such as the relative carcinogenic potencies, along with other evaluations of potential exposure and mismanagement, in deciding whether a waste is hazardous.
 
05/06/1986HEALTH ASSESSMENT INFORMATION IN LISTING DECISIONS; LISTING OF TF-1, AN ELECTRICAL TRANSFORMER FLUSHING AGENTMemo
 Description: The presence of Appendix VIII hazardous constituents or a combination of P-listed and U-listed ingredients are not the only factors in the listing determination for solvent TF-1. Concentration, migration potential, persistence, quantity generated, and management history are part of the determination. To be listed under on P- or U-list it must be a pure or technical grade of a listed solvent, or contain a sole active ingredient.
 
04/21/1986REGULATORY STATUS OF SOLVENT TF-1Memo
 Description: Part 261, Appendix VIII, hazardous constituents are not the only listing determination factor for solvent TF-1, there are other factors. Solvent and PCB wastes with Appendix VIII constituents are not hazardous waste unless they are listed or characteristic. TSCA has the authority to regulate PCB handling and disposal (SEE ALSO: 261.8).
 
04/29/1985PURPOSE OF DELISING PROVISIONSMemo
 Description: Most wastes are listed because of toxic constituents. The presence of constituents for which a waste is listed is not the sole criterion for delisting. Hazardous waste (HW) mixed with nonhazardous waste is hazardous. Dilution of HW with nonhazardous diluent generally is not a reasonable treatment option (SEE ALSO: 268.3).
 
09/04/1984RESPONSIBILITY OF GENERATOR IN HAZARDOUS WASTE DETERMINATIONSMemo
 Description: The applicability of hazardous waste regulations to SULFA-CHECK spent slurry is discussed. The suggested cyanide and sulfide concentrations for reactivity are less than 10 ppm (SUPERSEDED: see RPC# 4/21/98-01). A generator does not perform determinations in 261.11(a)(2) to classify a waste as hazardous, but rather uses the process established in 262.11 to make a hazardous waste determination.
 
08/01/1983ANTINEOPLASTIC DRUGSQuestion & Answer
 Description: Discusses U-listed antineoplastic (anticancer) drugs, including Cyclophosphamide (Cytoxin), Daunomycin, Melphalan, Mytomycin C, Streptozotocin.
