03/01/2013CLARIFICATION ON THE DILUTION OF LISTED F003 HAZARDOUS WASTEMemo
 Description: An F003 hazardous waste (listed solely for the characteristic of ignitability) is not a hazardous waste if the waste no longer exhibits any characteristic of hazardous waste per 40 CFR 261.3(g). However, F003 waste that is subsequently decharacterized is still subject to the Part 268 LDR requirements and may not be simply diluted as a substitute for adequate treatment (268.3) (SEE ALSO: R
 
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.
 
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.
 
02/21/2006STATE AUTHORIZATION AND GRANT OF VARIANCES Memo
 Description: The granting of a variance for partially reclaimed materials is determined on a case-by-case basis. States are authorized to implement this variance.
 
04/01/2004INTERSTATE SHIPMENTS OF WASTE LISTED SOLELY FOR IGNITABILITY, CORROSIVITY, OR REACTIVITYMemo
 Description: A transporter must have an EPA ID number, a manfiest, and comply with Part 263 if traveling through any state that recognizes the waste as hazardous. A TSDF is subject to the standards of the state where it is located.
 
02/12/2004APPLICABILITY OF THE F006 CLASSIFICATION TO WASTES FROM THE CHEMICAL ETCHING OF MAGNESIUMMemo
 Description: The applicability of hazardous waste listings is determined by the straight reading of regulatory language when specific processes are not mentioned. The F006 listing covers wastewater treatment sludges from certain electroplating operations. The listing applies to chemical etching, among other activities, and only excludes chemical etching of aluminum. Magnesium etching is not excluded, and wastewater treatment sludges generated from the chemical etching of magnesium are subject to the F006 listing. EPA's interpretation that the F006 listing applies to "common and precious metals" only applies in certain instances, but it did not affect anodizing, chemical etching and milling, or cleaning and stripping processes (SEE ALSO: 51 FR 43351; December 2, 1986). If a wastewater treatment sludge does not contain any constituents of concern for the F006 listing, the waste may be eligible for delisting.
 
08/19/2003REGULATORY STATUS OF OIL-BEARING SECONDARY MATERIALS UNDER RCRAMemo
 Description: Oil-bearing hazardous secondary materials generated from petroleum refining operations that can be legitimately recycled at petroleum refineries are excluded in 40 CFR 261.4(a)(12)(i) (SEE ALSO: 63 FR 42110; 8/6/1998). There is no minimum amount of oil required for the exclusion, but there must be recoverable amounts of hydrocarbons for legitimate recycling to occur. This exclusion applies to oil-bearing hazardous secondary materials, irrespective of whether they are listed or characteristic. Spent petroleum catalysts (K171-K172) may qualify for the exclusion. The exclusion only extends to materials actually inserted into the refinery process. The exclusion applies at the point of generation, even if preprocessing occurs, provided the conditions of the exclusion are met. The point of insertion into the refining process must be consistent with the material being recycled, and the material must be suitable for insertion. Materials may be inserted into the same refinery where they were generated or sent to another refinery. The materials cannot be sent to an intermediate non-refinery facility for processing. There is no limit on the number of transfers of the materials if recycling is legitimate and no speculative accumulation occurs. Processing equipment handling the materials is generally exempt from RCRA, since the material is excluded and the equipment is considered a process unit in 261.4(c). The processing equipment may be subject to RCRA if it contains reclamation residuals and no longer meets the process unit exclusion. The refinery does not need to own the equipment used to process and reclaim residuals to meet the exclusion.
 
12/01/2002REGULATORY STATUS OF SOLVENT RESIDUE FROM SPRAY CANSQuestion & Answer
 Description: Unused solvent removed from a non-empty spray can may meet a hazardous waste listing if the solvent is on the P or U list. The unused solvent might also exhibit a characteristic of hazardous waste. An unused solvent would not be classified as an F-listed spent solvent since it was never used. Hazardous waste determinations are the responsibility of the generator.
 
08/16/2002GENERATOR QUANTITY DETERMINATIONS FOR F006 LISTED SLUDGEMemo
 Description: A generator must include all hazardous waste that it generates when making quantity determinations. Hazardous waste generation is determined by the total volume of waste, not just by the quantity of hazardous constituents. Delisting procedures can address the regulation of low-risk, listed wastes. Provisions do not address adjusting the water content of listed waste (e.g., F006) when making quantity determinations. EPA is working with the metal finishing industry to tailor the regulations. EPA extended accumulation times for large quantity generators (LQGs) to 180 or 270 days when recovering metals from F006, and is working on other regulatory changes to encourage metal recovery (SEE ALSO: 65 FR 12377; 3/8/00).
 
07/17/2002SCOPE AND APPLICABILITY OF RCRA REGULATIONS AT WOOD PRESERVING FACILITIESMemo
 Description: Whether stormwater runoff from pentachlorophenol treated wood is a hazardous waste (e.g., F032) depends on site-specific factors. Stormwater that contacts preservative solutions or listed waste is hazardous via the contained-in policy. Precipitation runoff in storage yards is not F032 and drippage does not constitute illegal disposal, provided the facility complies with Subpart W. Steam from wood preserving equipment that condenses and settles away from the equipment is not F032, F034, or F035. A facility operating a tank-based zero discharge system is considered subject to the CWA for the purposes of the wastewater treatment unit (WWTU) definition. Drip pads are not required in storage yards, provided that any infrequent and incidental drippage is immediately responded to as outlined in the facility contingency plan. Infrequent and incidental drippage determinations are site-specific. Whether the presence of hazardous contaminants in soil indicates illegal disposal is determined on a case-by-case basis. State regulations can be more stringent.
 
01/01/2002F003 WASTES GENERATED PRIOR TO HWIR WASTE RULEQuestion & Answer
 Description: The new HWIR-Waste Rule is less stringent than the prior regulation, so states are not required to amend their authorized programs. In states authorized for the new exlcusion, wastes listed solely for exhibiting the characteristic of ignitability, corrosivity, or reactivity are no longer hazardous when they do not exhibit a characteristic. A mixture of a non-characteristic F003 waste generated after the effective date and a non-characteristic F003 waste generated before the effective date, will not carry the F003 waste code if resultant mixture is non-characteristic. If states are not authorized for 261.3(g), then the mixture would continue to carry the F003 code. (SEE ALSO: 66 FR 27266; 5/16/01)
 
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.
 
09/01/2001LAND DISPOSAL RESTRICTIONS FOR F001-F005 SOLVENT WASTESQuestion & Answer
 Description: Facilities generating F001-F005 spent solvent wastes containing carbon disulfide, cyclohexane, and methanol, along with other listed solvent constituents, need to treat only the wastewater forms of these three constituents. A facility must treat F003 and/or F005 spent solvents that contain only one or a combination of carbon disulfide, cyclohexane, and methanol to the concentration levels specified for this subcategory. If the F001-F005 waste is also characteristic, then the facility must meet the treatment standards for all UHCs including both the wastewater and nonwastewater standards for carbon disulfide, cyclohexane, and/or methanol.
 
01/26/2001VARIANCE FOR WORLD RESOURCE COMPANYMemo
 Description: EPA expects to make a final determination by the end of year regarding World Resources Company’s application for a variance from the definition of solid waste. If granted, their electroplating wastewater treatment sludge would not be a solid waste, and thus not a hazardous waste (F006).
 
02/01/2000Environmental Fact Sheet: Final Rule Promotes Metals Recovery from Waste Water Treatment Sludge (F006)Publication
 Description: This factsheet discusses the final rule to promote metals recovery from waste water treatment sludge (F006). EPA is encouraging metals recovery by allowing large quantity generators of F006 waste up to 180 days (or 270 days, if applicable) to accumulate F006 waste on site without a hazardous waste storage permit or interim status, provided that these generators meet certain conditions.
 
09/13/1999SLUDGES FROM WASTEWATER MIXTURESMemo
 Description: Wastewater treatment sludges from mixture of wastewater that is precursor to listed waste sludge and wastewater that is not precursor to listed waste sludge are covered by listing description (e.g., F006, F012, F019, K001-K007, K151, K106, K032, K035, K037, K040, K041, K044, K046, K066, K084). United States v. Bethlehem Steel Corp. decision held that F006 listing did not apply to sludges from combined wastewater streams. Bethlehem Steel decision binding only on district courts in Seventh District (independent of the mixture rule). Sludges from mixed wastewaters are RCRA hazardous wastes under mixture rule (261.3(a)(2)(iv)), regardless of the court’s decision.
 
05/12/1999ELECTROPLATING WASTEWATER TREATMENT SLUDGES FROM GRAY CAST IRON MANUFACTURING OPERATIONSMemo
 Description: Exclusion from F006 for zinc plating on carbon steel does not apply to plating on gray cast iron, a different base metal. Wastes from gray cast iron plating operations are eligible for delisting petition.
 
03/29/1999CLARIFICATION OF WOOD SURFACE PROTECTION AND WOOD PRESERVING DEFINITIONSMemo
 Description: Distinction between wood surface protection and wood preserving is based upon intent of process. Wood preserving is intended to protect physical integrity of wood. Surface protection is intended to prevent surface discoloration (SEE ALSO: 58 FR 25706; 4/27/93). Media actively managed which contain F032 waste would carry F032 listing.
 
01/01/1999PICKLING BATH CARRYOVER AND K062Question & Answer
 Description: Rinsewater contaminated with small amounts of pickling liquor carried over (carryover, dragout) to rinse tanks during normal steel finishing process is not considered K062 via the mixture rule. The pickling solution is a material in use, and is not waste until it is spent and removed from the process (SEE ALSO: RPC# 4/7/88-01; RPC# 7/28/87-02).
 
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.
 
08/18/1998STEEL PLATING PROCESS AND F006 DEFINITIONMemo
 Description: Wastewater treatment sludges from electroplating operations are F006 regardless of actual composition and constituent concentrations (even if the process does not use any of the constituents for which F006 sludges were listed, such as chromium, cadmium, nickel and cyanide). F006 exemption for aluminum or zinc-aluminum plating on carbon steel does not extend to steel plating on aluminum. Facility may petition to have waste delisted.
 
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.
 
06/01/1997AIR EMISSIONS FROM ELECTROPLATING OPERATIONSQuestion & Answer
 Description: A filter used to concentrate air emissions from electroplating line would not carry the F006 listing. The filter meets the definition of sludge, but does not result from the treatment of an electroplating wastewater. Air emissions are not wastewater.
 
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.
 
02/01/1997K061, K062, AND F006 HTMR SLAG RESIDUES AND USE CONSTITUTING DISPOSALQuestion & Answer
 Description: EPA is reevaluating the proposal on standards for management and use of slag residues derived from high temperature metals recovery (HTMR) treatment of K061, K062, and F006 wastes (12/29/94; 59 FR 67256). EPA may withdraw, repropose, or request additional comment. Use of K061, K062, and F006 slag residue as anti-skid/deicing material is prohibited. Use constituting disposal of slag residue is subject to Section 266.20(b).
 
01/21/1997REGULATORY STATUS OF ION EXCHANGE RESIN WASTEMemo
 Description: Ion exchange filter waste used in the treatment of electroplating rinsewaters is F006, even though purified water is recycled to process. An ion exchange filter is classified as a sludge. The definition of sludge is tied to type of unit in which the waste is generated.
 
12/24/1996CLASSIFICATION OF SOLVENTS ADDEDMemo
 Description: Solvent used as reactants or ingredients in a product are not F-listed spent solvents. The policy also applies to discarded unused product containing solvent. The policy applies to solvents which are added by the end user to adjust viscosity. Statements to the contrary in the Solvent Study (EPA530-R-96-017) (August 1996) and Listing Determination Background Document for the 8/14/96 solvent listing proposal (61 FR 42318) are incorrect.
 
08/30/1996CHEMICAL CONVERSION OF ALUMINUM AND WHETHER WASTEWATER TREATMENT SLUDGE GENERATED IS CONSIDERED AN F019 HAZARDOUS WASTEMemo
 Description: Sludge from an aluminum powder preparation process involving phosphating (but not zirconium phosphating) meets the F019 listing. Phosphating includes producing a mildly protective layer of insoluble crystalline phosphate on the surface of a metal. All wastewater treatment sludges from the chemical conversion coating of aluminum, except zirconium phosphating, are covered by the F019 listing, regardless of their composition and constituent concentration. (SUPERCEDES Brandes to Wozniak; 2/27/95 (RO 11940))
 
06/19/1996JURISDICTIONAL STATUS UNDER THE RCRA OF CERTAIN METAL-RICH SLUDGESMemo
 Description: Wastewater treatment sludge (F006) sent to primary smelters for copper extraction is not eligible for the Section 261.2(e) use/reuse exemption because the sludge is being reclaimed. Sludge may be eligible for a variance from the definition of solid waste under Section 260.30(c) as a partially reclaimed material needing further reclamation.
 
06/04/1996CLARIFICATION OF REQUIREMENTS INVOLVING THE COUNTING OF WOOD PRESERVING WATERS FOR BIENNIAL REPORTINGMemo
 Description: Hazardous wastewater from wood preserving plants (F032, F034, and F035) is not subject to quantity determination for the Biennial Report or for determining generator status when recycled in an on-site process without prior storage or accumulation (SEE ALSO: Section 261.4(a)(9)). If the waste is stored or accumulated prior to reuse, the generator must count the waste unless it has already been counted once.
 
03/07/1996INDUSTRIAL WIPERS AND THE HAZARDOUS WASTE IDENTIFICATION RULEMemo
 Description: Discusses possible factors to consider in a future rulemaking on disposable and reusable rags and wipers contaminated with solvents (SEE ALSO: RPC# 10/27/94-01 and RPC# 2/14/94-01).
 
07/18/1995DETERMINATION OF EQUIVALENT TREATMENT (DET) FOR F024 FOR WHICH INCINERATION IS BDATMemo
 Description: The proposed treatment of F024 using catalytic extraction processing would provide the treatment equivalent to the promulgated treatment standard, INCIN (incineration). This determination of equivalent treatment (DET) pursuant to 268.42(b) applies to specific facilities. Additional sites may be covered by a DET if the technology is expected to be commercially deployed at other sites and the company requests a DET.
 
06/30/1995DETERMINATION WHETHER SECONDARY MATERIAL TRANSPORTED TO A CANADIAN COPPER SMELTER IS A SOLID WASTEMemo
 Description: Although dewatering is reclamation, dried metal hydroxide solids in pellet powder from dewatering electroplating wastewater are F006. The listing applies even if the sludge is reclaimed further. Pellets sent to a smelter to recover metals are reclaimed, not directly used or reused, because distinct components are recovered as separate end products. The sludge is F006 before reclamation unless a variance from the definition of solid waste for partially-reclaimed wastes needing further reclamation (260.30(c)) is obtained.
 
05/25/1995REGULATORY STATUS OF A GASIFICATION UNIT PROPOSED BY TEXACO TO BE BUILT IN EL DORADO, KANSASMemo
 Description: Syngas fuel from a gasification unit at a Kansas petroleum refinery is derived from F037, K022, and K051, but is exempt fuel from refining oil-bearing hazardous waste during normal refinery operations per 261.6(a)(3)(iv) (SUPERSEDED: exemption moved to 261.6(a)(3)(iii)). The gasification unit is an exempt recycling unit. No storage permit is needed for listed feedstocks prior to recycling if the generator accumulation limit is not exceeded. This interpretation does not apply to all gasification units.
 
02/27/1995CLARIFICATION OF F006/F019 INTERPRETIVE LETTER REGARDING WASTES GENERATED FROM AN ALUMINUM COATING PROCESSMemo
 Description: Wastewater treatment sludges from anodizing aluminum in sulfuric acid are excluded from the F006 listing. Sealing and coloring anodized aluminum are not processes covered by the F006 or F019 listing if no chromates or cyanides are used. Electrodeposition with a clear acrylic film does not generate a listed hazardous waste if no chromate or cyanides are used. (SUPERCEDED BY: Bussard to Environmental Science Services; 8/30/96 (RO 14103))
 
02/16/1995RESPONSE TO PETITION ON PROHIBITION OF USE OF SLAG FROM HIGH TEMPERATURE METALS RECOVERY AS ANTI-SKID/DEICING AGENTMemo
 Description: The 266.20 use constituting disposal regulations effectively prohibit the use of slag derived from high temperature metals recovery (HTMR) of K061, K062, and F006 for anti-skid or deicing agents. HTMR residues may contain high concentrations of metals. EPA is not confident that K061, K062, and F006 used in this manner have been treated to minimize any threat.
 
02/10/1995CLARIFICATION OF THE LDR PHASE II REGULATION THAT APPEARED IN THE FEDERAL REGISTER ON SEPTEMBER 19, 1994Memo
 Description: SW-846 need not be used to demonstrate compliance with the universal treatment standards (UTS). When organic waste are combusted, nondetect values within an order of magnitude of UTS are acceptable. Notification for F001-F005, F039, D001, D002, D012-43 must include the constituents to be monitored if monitoring will not involve all UTS constituents.
 
12/01/1994ELEMENTARY NEUTRALIZATION UNITS GENERATING AND STORING NON-CORROSIVE HAZARDOUS WASTESQuestion & Answer
 Description: A tank in which corrosive-only (D002) electroplating wastewaters are treated meets the definition of elementary neutralization unit (ENU), even if the treatment process produces an F006 sludge. F006 is subject to regulation once it is removed from the tank.
 
10/27/1994REGULATORY STATUS OF INDUSTRIAL WIPERS UNDER RCRAMemo
 Description: The EPA Headquarters deferral on the determination of the regulatory status of rags and wipers to the appropriate Region or State implementing agency (SEE ALSO: RPC# 2/14/94-01) is discussed.
 
09/28/1994CLARIFICATION ON: MANIFEST DOCUMENT NUMBER; F003, F005, D001; WASTE DESTINED FOR RECYCLING; AND TREATMENT STANDARDS FOR CFCMemo
 Description: F003 and F005 waste exhibiting ignitability must carry a notification for and meet the D001 treatment standard (TS), since F003/F005 does not operate in lieu of D001 (SEE ALSO: 55 FR 22520, 22530; 6/1/90) (USE WITH CAUTION: see RPC# 3/1/94-02). The TS for chlorinated fluorocarbons (CFC) is discussed. A CFC waste may be subject to the California list prohibition for halogenated organic compounds (HOC) (SUPERSEDED: California list removed, see 62 FR 25997; 5/12/97) (SEE ALSO: RPC# 5/16/91-01). Materials that are not a solid waste (SW) when recycled are exempt even if shipped to a recycler via a TSDF. Scrap metal is both a SW and is hazardous, but is exempt if recycled. The legitimacy of recycling must be documented. Use of manifest continuation sheets is outlined.
 
09/21/1994APPLICABILITY OF F006 HAZARDOUS WASTE CODE TO NICKEL RECLAMATION PROCESS FOR ELECTROLESS NICKEL PLATING SPENT SOLUTIONSMemo
 Description: Electroless plating is not covered by the F006 listing. Spent electroless nickel solutions may be hazardous waste if mixed with a listed hazardous waste, if derived from a listed hazardous waste, or if they exhibit a characteristic. Because the scrap metal definition is based on physical form, the determination of whether nickel-plated steel wool generated during nickel-recovery is scrap metal should be made by the State or Regional office.
 
08/22/1994REGULATORY STATUS OF FOAM MATERIALS FROM THE USE OF CFCS, HCFCS, AND HFCS AS BLOWING AGENTSMemo
 Description: The attachment is an information sheet on CFC, HCFC, HFC blowing agents, solvents, and refrigerants. Foam products containing CFCs used as physical blowing agents are not listed hazardous wastes (SEE ALSO: RPC# 2/26/90-01). Spent trichlorofluoromethane and 1,1,2-trichloro-1,2,2-trifluoroethane used as solvents or reaction media are listed hazardous wastes. CFCs and HCFCs used in degreasing are F001. F001 listing description does not include HFCs. Used chlorofluorocarbon refrigerants from totally enclosed heat transfer equipment are excluded under 261.4(b)(12), provided the refrigerant is reclaimed for further use. This guidance provides the definition of treatment.
 
08/15/1994Environmental Fact Sheet: Certain Hazardous Waste Slag Uses Now Subject to RegulationPublication
 Description: This fact sheet discusses regulations that prohibits anti skid/deicing uses of high-temperature metal recovery (HTMR) slag residues derived from hazardous wastes K061, K062, and F006, as waste-derived products placed on the land. The rule does not prohibit this use when these wastes comply with all federal requirements for the land disposal of hazardous waste and does not prohibit other uses of HTMR slags that comply with EPA requirements.
 
08/02/1994CLASSIFICATION OF WASTEWATER TREATMENT SLUDGE FROM THE REVISED ""ZINC-COBALT ALLOY PLATING ON CARBON STEEL"" PROCESSMemo
 Description: The exclusion from the F006 listing for zinc plating on carbon steel applies even if zinc-cobalt alloy is used instead of just zinc.
 
08/01/1994UNUSED FORMULATIONS CONTAINING SODIUM PENTACHLOROPHENATE ARE F027Question & Answer
 Description: Sodium pentachlorophenate is a compound derived from pentachlorophenol (PCP) and therefore meets the F027 listing when discarded unused.
 
07/21/1994REGULATORY INTERPRETATION FOR ION EXCHANGE RESIN USED FOR WATER REUSE ON ELECTROPLATING WASTEWATERSMemo
 Description: The sludge definition is tied to the type of unit in which a waste is generated, not the disposition of the treated effluent or the intent of processing. Ion exchange resin used to filter electroplating wastewater is F006 regardless of whether it exhibits a hazardous characteristic. The act of filtering contaminants from wastewater is pollution control and generates a sludge, even if the intent is to reclaim the wastewater for reuse in a production process.
 
07/18/1994WASTE MINIMIZATION REQUIREMENTS OF SECTION 3002(B) OF RCRA FOR HAZARDOUS WASTE DISPOSAL FACILITIESMemo
 Description: The 3005(h) waste minimization and certification requirements apply to an owner of a landfill that generates and has a RCRA Subtitle C treatment permit for F039 leachate. If the owner is a large quantity generator (LQG) and sends the waste off-site, the owner is also subject to the 3002(b) waste minimization requirements. There is no statutory exemption from waste minimization certification for facilities generating remedial waste.
 
07/15/1994APPLICABILITY OF HAZARDOUS WASTE CODES TO A CHEMICAL POLISHING SYSTEMMemo
 Description: Discarded chemical polishing bath solution containing the oxidizer hydrogen peroxide may be ignitable (D001) because it is capable of severely exacerbating a fire by yielding oxygen to stimulate combustion. Acid baths may be corrosive (D002) due to sulfuric acid content. The chemical polishing process does not generate a listed waste if no electroplating or cyanides are used (SUPERSEDED: Memorandum, Dellinger to Waterman; May 18, 2007 (RO 14808)). Discarded baths from this process are hazardous wastes only if characteristic. Wastes that exhibit a characteristic at the point of generation may be subject to the Part 268 requirements even if they do not exhibit a characteristic at the point of disposal (261.3(d)(1)).
 
07/12/1994REGULATORY INTERPRETATION REGARDING PHOTORESIST SOLIDS (""SKINS"") GENERATED IN THE PRINTED CIRCUIT BOARD MANUFACTURING INDUSTRYMemo
 Description: Cleaning and stripping is electroplating only if associated with (i.e., in line or contiguous with) other electroplating operations. Wastes from printed circuit board manufacturing can be F006 if electroplating operations are involved. Stripping solutions or baths can be electroplating wastewaters. Photoresist solids or "skins" filtered from stripping solutions in the printed circuit board industry can be F006 sludges.
 
06/01/1994SCOPE OF SPENT SOLVENT LISTINGSMemo
 Description: EPA has not established numerical levels for solvent contamination in nonhazardous manufacturing process wastes that trigger hazardous waste regulation. If listed solvent hazardous waste in any amount is mixed with other solid waste, the mixture is listed (SEE ALSO: 261.3(a)(2)(iv) exemption; RPC# 10/20/92-02).
 
06/01/1994TECHNICAL GRADE SOLVENT FORMULATIONS AND THE F003 LISTINGQuestion & Answer
 Description: The F003 listing covers pure solvent mixtures as well as technical grade solvent formulations used for their solvent properties. Discusses the definition of technical grade. A solvent can contain de minimis concentrations of contaminants or impurities and still meet the F003 listing.
 
04/08/1994REGULATORY STATUS OF WOOD STICKERS USED FOR WOOD PRESERVING OPERATIONSMemo
 Description: Although the F032, F034, and F035 listings do not generally apply to treated wood products that are discarded, wood "stickers" (pieces of wood used during wood preserving to separate bundles of lumber) that come into contact with wood preservative are listed hazardous waste when discarded.
 
03/22/1994CLARIFICATION OF THE ""CONTAINED-IN"" POLICYMemo
 Description: Soil containing F003 (listed solely for ignitability) may be deemed to contain hazardous waste due to the presence of hazardous constituents (such as metals) even if the soil does not exhibit a characteristic under the contained-in policy (SEE ALSO: 66 FR 27266, 27286; 5/16/01). Consistent with the process for delisting wastes listed solely for a characteristic, States may consider constituents other than those for which the waste was listed when deciding if the soil still contains hazardous waste.
 
03/01/1994CLARIFICATION OF LAND DISPOSAL RESTRICTIONS (LDR) REQUIREMENTSMemo
 Description: If a waste is ignitable (D001, high total organic carbon (TOC)) and exhibits the toxicity characteristic for lead (D008), then blending and combustion as a hazardous waste fuel is not impermissible dilution, since the treatment standard for high TOC D001 requires burning. Fuel substitution alone is not sufficient. Ash from burning such metal-bearing wastes must meet the treatment standards for metals. A waste must meet treatment standards for all applicable waste codes before land disposal (SEE ALSO: 268.9(b)). The F001-F005 treatment standards apply only to the constituents used for solvent properties and which triggered the listing. Solvent constituents picked up through use are not subject to the F001-F005 treatment standards. The F005 treatment standard addresses the characteristic of ignitability and so operates in lieu of D001 treatment standard (USE WITH CAUTION: see RPC# 9/28/94 -04). The alternative debris treatment standards may be used even if the debris is contaminated with a waste code whose treatment standard is a specified technology.
 
12/01/1993APPLICABILITY OF PART 279 TO WASTE GREASEMemo
 Description: A material fits within the definition of used oil (UO) if it is used for the same purpose as used oil, mixed and managed in the same manner as used oil after use, and presents the same level of hazard as used oil (SEE ALSO: 57 FR 41574; 9/10/92). Used grease may be considered used oil, provided it is recycled and meets the 1000 ppm total halogen criteria. Used grease containing 10% or more of an F-listed solvent will typically not meet an F-listing, unless the F-listed ingredient is used for its solvent properties. Persons can rebut the presumption that the grease was mixed with a listed waste by documenting the use of F-listed solvents for other than their solvent properties. A facility burning used oil in an incinerator for disposal may be subject to maximum achievable control technology (MACT) standards.
 
10/13/1993LAND DISPOSAL RESTRICTION INTERIM FINAL RULEMemo
 Description: Discusses the applicability of the interim final rule (58 FR 29884; 5/24/93) to wastes that have one or more numerical treatment standards as well as a deactivation requirement. F001 waste that is also corrosive (D002) must be treated to meet the standards for both waste codes (including treatment for underlying hazardous constituents). Waste mixtures with common constituents of concern must meet the most stringent standard that applies. Ignitable (D001) and corrosive wastes (subject to treatment for underlying hazardous constituents) may be aggregated with other compatible wastes to facilitate treatment. Aggregating wastes for other purposes may be impermissible dilution.
 
09/01/1993HAZARDOUS WASTE RECYCLING REGULATIONS TO A PROPOSED INK RECYCLING PROCESSMemo
 Description: Waste ink is a spent material. Spent materials are solid wastes when they are reclaimed. Process recycling waste ink is not regulated under RCRA Subtitle C. The storage of waste ink prior to recycling is subject to permit standards. Whether a temporary holding area is subject to permitting is decided on a case-by-case basis. Lithographic printers may qualify as CESQGs (SEE ALSO: RPC# 9/20/93-03). Waste ink may be characteristic or listed, depending on the type of solvent used to clean the ink machine. Hazardous waste recyclers must notify EPA under RCRA 3010 and obtain EPA ID numbers. Residues from the recycling process may no longer be solid wastes if they are legitimate products. Discusses the regulatory status of reclaimed materials and legitimacy determinations.
 
06/01/1993UNUSED FORMULATIONS OF AGENT ORANGEQuestion & Answer
 Description: Unused formulations of Agent Orange meet the F027 listing when discarded because Agent Orange contains 2,4,5-T, a compound derived from the synthesis of trichlorophenol.
 
05/01/1993WASTE CLASSIFIED AS BOTH F005 AND K086Question & Answer
 Description: Washes and sludges generated from cleaning an ink pigment mixing tub using an 80 percent toluene solvent is classified as F005 and K086. For purposes of land disposal restrictions (LDR), the generator must also determine applicable characteristics.
 
04/19/1993DISCUSSION PAPER ON POSSIBLE UNIVERSAL WASTEMemo
 Description: EPA is evaluating the applicability of the household hazardous waste (HHW) exclusion to lead-based paint abatement wastes (SEE ALSO: 63 FR 70233, 70241; 12/18/98). Part 279 prohibits the storage of used oil in unlined surface impoundments and applying used oil to roads. Fluorescent bulbs may be conditionally exempt in the future. EPA does not believe that F001-F005 solvents should be included as universal wastes. EPA is currently studying other solvent wastes to determine if they merit a listing (SEE ALSO: 61 FR 42318; 8/14/96). Spent antifreeze may exhibit the toxicity characteristic for lead and/or benzene. EPA is evaluating toxicity characteristic levels for lead and pentachlorophenol (PCP). New MCLs could affect future toxicity characteristic levels. Sandblast grit from the removal of lead-based paint may be D008.
 
03/04/1993PETITION FOR EXCLUSION OF WESTERN WHEEL HOWELL F019 WASTEMemo
 Description: Wastewater treatment sludges that are generated from the treatment of contaminated rinsewaters collected from the stages prior to chromate conversion coating are not F019, provided that these wastewaters are kept separate from the wastewaters from the chromate conversion step.
 
12/24/1992CLARIFICATION ON WHAT CONSTITUTES DIOXIN RELATED MATERIALSMemo
 Description: Contains a list of waste codes that contain dioxin (F020, F022, F023, F026, F027, F028, F032, D017, D041, D042). The F-listed dioxin waste codes do not apply if waste contains dioxin but does not meet the listing description. Waste exhibits the toxicity characteristic only if the level of constituent exceeds the regulatory level. F039, K043, and K099 have land disposal restrictions (LDR) for certain dioxins and furans. If waste meets the listing description, the waste code applies even if no Appendix VIII constituents are present. For purposes of F021, a pentachlorophenol derivative includes any substance which is related structurally and can be made from pentachlorophenol (PCP), including sodium pentachlorophenate, octachlorodibenzodioxin, octachlorodiphenyl ether, and potassium pentachlorophenate. Derivatives from tri- and tetrachlorophenol include tri- and tetra-chlorophenoxy derivatives of carboxylic acids. F020 -F023, F026-F028 hazardous waste must be incinerated in an unit meeting 99.9999 DRE or burned in thermal treatment unit meeting same DRE. Waste that contains Appendix VII constituents but cannot be traced to the original process that would generate the waste meeting listing description is exempt from regulation unless characteristic.
 
12/22/1992IDENTIFICATION OF SPENT SOLVENT IN CERTAIN INDUSTRIAL PROCESSESMemo
 Description: Toluene-containing polyurethane coating used in the manufacture of marine buoys and fenders is not F005 when used to mechanically clear a spray gun nozzle (i.e., not solubilizing) as long as the solvent is not used for its solvent properties.
 
12/11/1992CLARIFICATION OF HAZARDOUS WASTE LISTINGS PERTAINING TO WOOD PRESERVING OPERATIONSMemo
 Description: Wood preserving is defined as any process intended to preserve wood from structural attack. The definition is based on intent of treatment, not on type of process. Dipping operations could be wood preserving. Sodium pentachlorophenate used as wood preservative is F032 when discarded.
 
12/01/1992HYDROCHLOROFLUOROCARBONS USED IN DEGREASINGQuestion & Answer
 Description: Hydrochlorofluorocarbons (HCFCs) used in degreasing are F001 if the concentration was 10% before use. Hydrogenated fluorocarbons (HFCs) are not F001.
 
11/04/1992CLASSIFICATION OF F003 WASTESMemo
 Description: Xylene and acetone used to remove paint is F003, even if the waste is not ignitable. The 261.3(a)(2)(iii) mixture rule exemption does not apply to nonignitable F003 that has not yet been mixed with solid waste, and does not apply to a mixture of soil and F003 that does not exhibit a characteristic (SEE ALSO: 66 FR 27266; 5/16/01). Land disposal restrictions (LDR) treatment requirements still apply to F003 waste that has been rendered nonignitable and/or nonhazardous under 261.3(a)(2)(iii). If F003 is spilled into soil, the soil must be managed as listed waste until the state or Region determines that it no longer contains hazardous waste.
 
10/20/1992REGULATORY STATUS OF WASTE GENERATED BY MCLAUGHLIN GORMLEY KING (MGK) COMPANY IN MINNESOTAMemo
 Description: F001-F005 solvents such as toluene that are used as carriers, extractants, reaction media, etc., are listed hazardous wastes when spent and separated from the process in which they were used, but other wastes that are separated from the final product containing trace amounts of solvents picked up during the production process are not F001-F005 or listed via the mixture rule.
 
10/01/1992PERCHLOROETHYLENE USED IN DRY CLEANINGQuestion & Answer
 Description: Spent tetrachloroethylene (perchloroethylene) used in dry cleaning is classified as F002. The F001 listing is limited to solvents used in degreasing.
 
09/18/1992REQUEST FOR CLARIFICATION ON F019 WASTE DETERMINATIONMemo
 Description: Wastewater treatment sludges from the conversion coating operation are F019 regardless of where in the wastewater treatment train they are generated. The listings apply regardless of whether there is prior treatment or commingling with other wastewaters, even if the sludges contain very low concentrations of hazardous constituents. The concentration-based standards under CWA are not a factor.
 
08/17/1992WASTE GENERATED DURING THE MANUFACTURE OF POLYURETHANE FOAMMemo
 Description: Wastes from the normal use or discard of toluene and polyurethane coating formulation are not F001-F005 (the solvent is used as an ingredient). If an identical formulation is used to clean a spray gun or equipment, then the resulting wastes can be F001-F005. In all cases, the waste must be evaluated for characteristics.
 
07/16/1992REGULATORY DETERMINATION - SPENT SOLVENT LISTINGS AND THE MIXTURE RULEMemo
 Description: The Shell Oil decision on the mixture rule does not affect the scope of the spent solvent listings (F001-F005). A spent solvent is not a “mixture” of solvent and its contaminants.
 
01/15/1992REQUEST FOR ASSISTANCE REGARDING F006 DETERMINATION AT THE EAGLE-PICHER COLORADO SPRINGS, COLORADO FACILITYMemo
 Description: EPA defines electroplating as the reduction or plating of metal ions on a cathodic surface. Electrolysis is not electroplating. A facility does not need to be subject to CWA electroplating effluent standards in order to generate wastes within the scope of the F006-F009 and F019 listings.
 
12/01/1991RECLAIMED SPENT WOOD PRESERVATIVE EXCLUSION IN 40 CFR 261.4(A)(9)Question & Answer
 Description: Spent wood preserving solutions that are reclaimed are no longer solid wastes and so are not derived from listed wastes F032, F034, or F035 (SEE ALSO: 63 FR 28556; May 26, 1998). Wood treated with the reclaimed preservative is not a hazardous waste when placed on land.
 
11/26/1991DISCARDED WASTEWATER AT A CORROSION CONTROL FACILITYMemo
 Description: Discarded wastewater containing methylene chloride at a corrosion control facility is a solid waste. There is insufficient information to determine if the waste is hazardous. Methylene chloride is listed under both F001 and F002.
 
11/01/1991MULTISOURCE LEACHATE (F039) WASTE CODE AS IT APPLIES TO CONTAMINATION FROM SPILLSQuestion & Answer
 Description: Water that has percolated through soils contaminated with more than one listed hazardous waste is normally F039, since spills and drips of hazardous waste which have collected in soil are normally land disposed wastes.
 
09/04/1991RCRA ARAR DETERMINATION AT MAXEY FLATS SUPERFUND SITEMemo
 Description: Vials containing waste radioactive scintillation cocktails using xylene or toluene as a reaction medium are F003 and/or F005 if they meet the applicable solvent percentage thresholds (SEE ALSO: RPC# 3/1/89-04). If they are listed or characteristic, the cocktails must be managed as RCRA hazardous wastes.
 
08/30/1991RESIDUALS MATERIALS CONTAMINATED WITH TRACE SOLVENTSMemo
 Description: Discusses solvent carryover. When a metal part is cleaned using an F-listed solvent, then air dried and blasted, the blasting grit containing trace levels of the solvent is not F001-F005 or listed via the mixture rule. If the solvent was used in excessive amounts during the initial cleaning, the solvent in the grit could be F-listed.
 
07/31/1991TC RULE HAZARDOUS WASTE DETERMINATIONMemo
 Description: Pulp and paper mill wastes should be sampled at an outlet from the bleach plant (point of generation), prior to commingling (mixing) with other wastestreams, to determine whether they exhibit the toxicity characteristic for chloroform (D022). The dilution of characteristic hazardous waste at a pulp and paper mill is acceptable for CWA compliance provided there is no specified method of treatment (58 FR 29860; 5/24/93). The definition of aggressive biological treatment (ABT) units for the purposes of the F037 and F038 listings does not apply to the exemption for biological treatment units from the surface impoundment minimum technical requirements.
 
07/05/1991APPLICABILITY OF THE “MIXTURE” RULE TO PETROLEUM REFINERY WASTEWATER SYSTEMS Memo
 Description: Addresses petroleum wastewater separation sludges. Liquid from which F037 and F038 listed sludge is generated is not itself a listed waste via the mixture rule unless the sludge is mixed with the liquid (e.g., sludge is scoured upon the introduction of the waste to the unit).
 
07/03/1991DRAFT REGION VIII POLICY ON “AGGRESSIVE BIOLOGICAL TREATMENT”Memo
 Description: Sludges formed in aggressive biological treatment (ABT) units are not F037 or F038. Only secondary or tertiary treatment units qualify as ABT units. ABT units receiving or generating toxicity characteristic hazardous waste are subject to all applicable rules. F037/F038 sludges can be formed in ABT units that are not operating properly.
 
06/01/1991ADMINISTRATIVE STAY FOR WOOD PRESERVING WASTESQuestion & Answer
 Description: Description of administrative stay of the effective date for wood preserving wastes F032, F034, and F035.
 
05/31/1991DRIPPAGE IN WOOD PRESERVING STORAGE YARDSMemo
 Description: Incidental drippage after the removal of treated wood from drip pad is not illegal hazardous waste disposal, provided the owner and/or operator responds immediately. An immediate response determination is site-specific. A facility must have a contingency plan and must keep records of the response.
 
05/29/1991ELECTROPLATING WASTESMemo
 Description: Anode bags are spent materials when removed from electroplating bath for reclamation. Spent anode bags are both reactive (D003) and F007. Bags can be washed in an accumulation tank/container without a permit under Section 262.34. Filter media, and residue from the apparatus used to filter cyanide plating bath are D003 (reactive) and F008, but not F007. A cleaning bath that does not contain cyanides is not F009.
 
05/01/1991COMPARATIVE DEFINITIONS OF F001 AND F002Question & Answer
 Description: The type of degreasing determines whether tetrachloroethylene, trichloroethylene, methylene chloride, and 1,1,1-trichloroethylene receive the F001 or F002 listings. F001 applies to large-scale industrial degreasing, and F002 applies to equipment cleaning, and smaller scale degreasing operations.
 
03/07/1991DELISTING PETITION - FUJI PHOTO FILM WASTEWATER TREATMENT SLUDGEMemo
 Description: The metal treatment process is not chemical conversion coating of aluminum (i.e., does not create F019) if it does not involve chromate compounds or oxide, phosphate, or chromate conversion.
 
02/01/1991PETROLEUM REFINERY WASTEWATER TREATMENT SLUDGE CLASSIFICATIONQuestion & Answer
 Description: Discusses the applicability of the F037 and F038 listings, primary/ secondary separation, and primary/ secondary treatment.
 
01/23/1991REGULATORY STATUS OF SOLVENT-CONTAMINATED RAGS AND WIPERSMemo
 Description: Until EPA has the resources to respond to a petition to exempt solvent-contaminated rags, wipers, and shop towels from the mixture rule, EPA believes the waste determination should be made by the state or region on a case-by-case basis since they are in the best position to make an evaluation.
 
01/01/1991CLASSIFICATION OF LEACHATE CONTAMINATED GROUND WATERQuestion & Answer
 Description: Groundwater contaminated with leachate resulting from the disposal of multiple listed wastes contains F039. F039 wastewaters destined for underground injection received a two-year national capacity variance.
 
10/17/1990PETROLEUM REFINERY SLUDGE REGULATIONSMemo
 Description: Contains EPA’s response to issues raised during the Office of Management and Budget (OMB) review of petroleum refinery sludge final rule listing F037 and F038.
 
08/17/1990CAPACITY VARIANCES FOR UNDERGROUND INJECTION FACILITIESMemo
 Description: To EPA's knowledge, all commercial facilities with hazardous waste injection (UIC) wells disposing of on-site clean-up wastes have received final approval of no-migration petitions. Deep-well injected F039 has a two-year capacity variance, whether it is injected on site or commercially off site.
 
08/15/1990TANK TREATMENT PROCESSESMemo
 Description: Circuit board manufacturing wastes can be F006 if electroplating is involved. Anodizing is electroplating. Chemical conversion coating is a non-electrical process and is not anodizing or electroplating for F006, F007, F008, F009. Wastewater is defined only for the land disposal restrictions (LDR). Containers and tanks storing hazardous waste (HW) before an off-site shipment are not wastewater treatment units (WWTUs). EPA did not intend to include containers in the definition of ancillary equipment. Generator accumulation starts when the waste first enters the container. HW sludge that is removed from a WWTU is subject to full regulation. A unit can be both a WWTU and an elementary neutralization unit (ENU). A wastewater treatment sludge is anything that precipitates or separates during treatment. F006 may be formed in an exempt unit.
 
08/02/1990APPLICABILITY OF F019 LISTING TO WASTEWATER TREATMENT SLUDGE FROM THE TIN COATING OF ALUMINUMMemo
 Description: The non-electrolytic tin phosphate coating of aluminum is chemical conversion coating. Wastewater treatment sludge from the phosphate coating process is F019, even if no hazardous constituents or characteristics are present.
 
07/31/1990MULTI-SOURCE LEACHATE AND TREATMENT STANDARDS OF LAND DISPOSAL RESTRICTIONSMemo
 Description: Waste codes not required on the manifest. A TSDF may rely on waste analysis data from the generator, but the TSDF must periodically test representative samples. A lab may certify for land disposal restrictions (LDR) as representative of the waste handler. Waste analysis parameters. Stabilization of cyanide to reduce leachability is an inappropriate treatment and generally impermissible dilution. No dilution of toxicity characteristic wastes if land disposed. Generators must determine characteristics. If a listed treatment standard addresses the characteristic, it operates in lieu of characteristic (even if less stringent). Prohibited waste only placed in a minimum technological requirement (MTR) surface impoundment if meets treatment standards, variance or extension, or 268.4. Notice and certification for de-characterized waste is sent to the implementing agency. F039 HSWA. Permitted TSDFs with F039 submit Class 1 modification by 8/8/90. Lab packs must be burned in Subpart O incinerator, not cement kilns.
 
07/25/1990THIRD THIRD REVISIONS TO F024 TREATMENT STANDARDSMemo
 Description: Pending the effective date of revised F024 treatment standards or a correction notice establishing an immediate effective date, treatment standards promulgated in the Second Third remain in effect (SEE ALSO: current 268.40).
 
06/25/1990F024 REVISED TREATMENT STANDARDSMemo
 Description: The Third Third revised the F024 treatment standard from a concentration standard to incineration. Pending effective date for new standard or correction notice establishing an immediate effective date, the Second Third treatment standard remains in effect.
 
06/20/1990CLARIFICATION OF SPENT SOLVENT LISTINGSMemo
 Description: If the total of all F001, F002, F004, or F005 solvents before use is 10% or more by volume, the waste from using solvent is listed and carries all applicable codes. F001-F005 codes can apply even if each F001-F005 constituent is under 10%. Trichloromethane (chloroform) is U044 or D022, not F-listed.
 
06/14/1990RCRA WASTE CLASSIFICATION OF LABORATORY STANDARDSMemo
 Description: F-listed solvent used to dissolve CCP to formulate lab standards use as an ingredient, not a solvent. Diluting or dissolving chemicals to make lab standard is not use. Discarded unused lab standards with P- or U-list chemicals are P-list or U-list hazardous waste if there is one active ingredient. The federal regulations do not require waste codes on the manifest, but the state may. If the waste is both listed and characteristic, it carries all applicable codes for land disposal restrictions (LDR) and incompatible waste.
 
06/13/1990USED OIL AND IDENTIFICATION OF LISTED HAZARDOUS WASTEMemo
 Description: F001-F005 "before use" is before use at the facility, not when purchased. If pure solvent was purchased, diluted below 10% concentration, and used as solvent, the waste is not F001-F005. Solvent before use has any amount F003 and 10% total F001, F002, F004, or F005, waste F003 and other applicable F001-F005 listings. The K list applies only to wastes from industrial sources in the listing description. In general, the primary SIC code for a facility does not dictate if the facility is within the K-list category. A commercially pure /technical grade undefined for the P- and U-lists. It can include purity grades marketed or in general use by industry. Part 266, Subpart E (SUPERSEDED: see Part 279) applied to used oil (UO) not mixed with listed hazardous waste burned for energy recovery. Characteristic UO recycled in manner other than burning for energy recovery is not subject to RCRA (SUPERSEDED: see Part 279).
 
06/12/1990CHEMICAL ETCHING PROCESS-HAZARDOUS WASTE IDENTIFICATIONMemo
 Description: Bright dipping is chemical etching, a type of electroplating. Wastewater treatment sludge from the bright dipping process is F006.
 
06/01/1990THE DEFINITION OF F001-F005 WASTEWATERQuestion & Answer
 Description: The terms “solvent-water mixture,” “F001-F005 wastewater,” and “aqueous solvent waste” are equivalent for the purposes of land disposal restrictions (LDR) treatment standards for solvent wastewaters (SUPERSEDED: Section 268.2(f)(1) definition of solvent-water mixture deleted, see 61 FR 15588; April 8, 1996).
 
05/03/1990PAINT SPRAY BOOTH AIR FILTERSMemo
 Description: The process wastes such as discarded paint and paint spray booth air filters containing toluene and xylene as ingredient in paint are not F001, F002, F003, F004, or F005.
 
05/02/1990ZIRCONIUM PHOSPHATING SLUDGES EXEMPTIONMemo
 Description: The exclusion from F019 listing apples to zirconium phosphating on aluminum cans when no cyanide, chromium, or other hazardous constituents are involved.
 
04/17/1990MARTIN MARIETTA - F019 WASTE LISTING DETERMINATIONMemo
 Description: Wastewater from chemical conversion coating of aluminum (electroplating waste) retains its identity while passing through the treatment train. Sludges generated in an initial treatment unit and subsequent units are all F019.
 
04/12/1990CADMIUM WASTES FROM MILITARY COATING MATERIALSMemo
 Description: Cadmium wastes from coating materials and spent sacrificial anodes generated by military operations may be F-listed electroplating, heat treating, or aluminum conversion coating wastes (F006, F019, F007, F008, F009, F010, F011, F012) or may exhibit EP (extraction procedure) Toxicity for cadmium (SUPERSEDED: see Section 261.24).
 
03/01/1990TREATMENT STANDARDS FOR METHANOL WHICH DOES NOT MEET THE F003 LISTINGQuestion & Answer
 Description: A generator need not include the methanol treatment standard in the land disposal restrictions (LDR) notification for F003 waste xylene with traces of methanol used as a fuel. The use of a solvent as a reactant or ingredient is not solvent use meeting listing (SUPERSEDED: no treatment standard on notification, see new 268.7(a)(2)).
 
02/26/1990CHLOROFLUOROCARBONS (CFCS) FROM PRODUCTION OF FOAM PRODUCTSMemo
 Description: CFCs used as blowing agents in production of foam insulation products (i.e., to physically open and expand the foam cells) are not considered used as solvents and are not F001-F005 when spent (SEE ALSO: RPC# 8/22/94-01).
 
10/20/1989DISPOSAL OR RECLAMATION OF RAGSMemo
 Description: Rags contaminated with volatiles and F-listed solvents through wipe down and cleaning processes may be incinerated or laundered (SUPERSEDED: see RPC# 2/14/94-01).
 
10/20/1989RAGS AND SIMILAR MATERIALS ABSORBING VOLATILES AND F-WASTES, HANDLINGMemo
 Description: Rags contaminated with volatiles and F-listed solvents through wipe down and cleaning processes may be incinerated or laundered (SUPERSEDED: see RPC# 2/14/94-01).
 
10/06/1989WASTEWATER TREATMENT SLUDGES CONTAINING METHANOLMemo
 Description: Wastewater treatment sludges containing small quantities of methanol are not necessarily listed or characteristic hazardous waste. Even if such waste is not hazardous under federal rules, more stringent or broader-in-scope state regulations can trigger regulation.
 
10/01/1989CLARIFICATION OF F019 LISTING AND APPLICABILITY TO OTHER WASTEWATER TREATMENT SLUDGESQuestion & Answer
 Description: Supernatant from the treatment of wastewaters from the chemical conversion coating of aluminum is not F019. Supernatant is hazardous if characteristic or if mixed with a listed sludge. Filtrate from a listed sludges is not hazardous via derived-from rule if similar to influent wastewater. Supernatant in which sludges are accidentally resuspended are listed.
 
10/01/1989CLARIFICATION OF SPENT SOLVENT LISTINGQuestion & Answer
 Description: CFC-11 (trichlorofluoromethane) used as blowing agent in the production of foam is not used for its solvent properties, and is not listed (SEE ALSO: RPC# 8/22/94-01).
 
09/22/1989TETRACHLOROETHYLENE CONTAMINATED WITH POLYCHLORINATED BIPHENYLS (PCBS)Memo
 Description: Cleaning PCBs from a transformer with solvent containing 10% or more tetrachloroethylene (PCE) before use results in F002 listed waste. Applicable TSCA PCB regulations do not supersede the RCRA regulations. If TSCA and RCRA rules conflict, the more stringent regulations take precedence. Using solvent as dielectric is not "solvent use" triggering F001-F005 listings.
 
08/23/1989REGULATORY STATUS OF F006 RECLAMATION PROCESSMemo
 Description: In order for slag residue derived from the processing of F006 and destined for use as an aggregate substitute to qualify as legitimately recycled, slag must be analogous to the normal feedstock it is replacing. The technical feasibility of using slag as substitute for aggregate does not mean slag recycling is legitimate. The state or Region determines the legitimacy of recycling on a site-specific basis. Persons claiming materials being recycled are not solid wastes must be able to document that there is a known (not potential) market for the recycled material. Discussion of sham recycling of F006 electroplating sludges. Slag derived from the treatment of F006 is also F006 in the absence of any exemptions.
 
08/21/1989P AND U-LISTED WASTESMemo
 Description: The P-and U-listings do not apply to chemicals listed in 261.33 that have been used for their intended purpose, but waste must still be evaluated for characteristics. If an unused chemical is no longer a technical or commercially pure grade due to contamination, it can still be an off-specification species of that chemical and so still meet the applicable P or U listing when discarded. Solvent CCPs that have been used for their solvent properties may meet one of F001-F005 listings.
 
08/21/1989WASTEWATER TREATMENT SLUDGES RESULTING FROM METAL CLEANING PROCESSMemo
 Description: The use of an electrical current is not a prerequisite for a process to be considered an electroplating operation for purposes of F006 listing (e.g., chemical etching does not involve an electrical current, but sludges from treating wastewaters from chemical etching meet F006 listing). Cleaning must be associated with electroplating operations for sludges from treatment of cleaning bath to be F006.
 
08/02/1989CHLOROFLUOROCARBONS (CFCS) AS REFRIGERANTS, RECYCLING OF SPENTMemo
 Description: Used CFC refrigerants are not hazardous waste F001 or F002 because they were not used as solvents, and are not U121 because they have been used. Such wastes are only hazardous if characteristic (SEE ALSO: 261.4(b)(12)).
 
08/02/1989SCOPE OF THE K051 AND K052 LISTINGSMemo
 Description: Sludges generated at bulk terminals are not typically within the scope of K051 and K052 listings (SEE ALSO: F037, F038 in 261.31). If K049, K051, or K052 wastes are shipped to a bulk terminal, wastes derived from their management meet the listings. The discharge of residuals from K049 storage to an oil-water separator could make the resulting sludge listed via the derived-from and mixture rules.
 
08/01/1989CLARIFICATION OF ELECTROPLATING LISTINGSQuestion & Answer
 Description: Definition of “electroplating operations” for F006 given in the December 2, 1986 Federal Register (54 FR 43351) and may be applied analogously to F007, F008, and F009. Electroless plating bath solutions will not meet F007, F008, and F009 listings even if they contain cyanide.
 
07/21/1989ACETONE AND METHANOL CONTAMINATED WASHWATERSMemo
 Description: When toluene is used as solvent in a production process and then recovered, trace quantities of toluene found in facility's washwaters are not normally F-listed spent solvents and do not render all facility wastewaters and sludges hazardous via the mixture rule. Using pure methanol and acetone as a drying agent to extract water from a product is solvent use, and resulting wastes are F003. If a product contains only F003 solvents before use, wastes from solvent use are F003. F003 that is nonignitable when generated is still F003 until mixed with solid waste and qualifies for 261.3(a)(2)(iii) mixture rule exemption (SEE ALSO: 66 FR 27266; 5/16/01). If a tanker truck holding P- and U-listed hazardous waste is rendered empty according to 261.7 (contents removed using "reasonable" means and less than one inch or 0.3% of tanker volume remains), water from subsequent rinsing is not regulated, even if it contains traces of P- or U-listed chemicals.
 
07/10/19891,1,1-TRICHLOROETHANE CONTAINED IN A SAND-METAL-SOLVENT MIXTUREMemo
 Description: If a metal part is degreased in F001-F005 solvent and then ground with sand, the resulting metal and sand waste containing traces of solvent is not F001-F005 or listed via mixture rule. The metal and sand mixture is considered a process waste contaminated with solvent that was not "spent" (SEE ALSO: RPC# 3/1/87-03).
 
07/06/1989SPENT CYANIDE PLATING BATH SOLUTIONS FROM SILVER RECOVERYMemo
 Description: An operation that recovers silver ions from cyanide bath is not an electroplating process, and resultant waste is not F007. Contains description of electroplating operations.
 
07/05/1989CHARACTERISTIC HAZARDOUS WASTE OR SOLID WASTE TREATMENT MAY CREATE A LISTED HAZARDOUS WASTEMemo
 Description: Waste derived from the treatment of waste listed solely for exhibiting a characteristic (e.g., F003) is listed unless mixed with solid waste and the mixture no longer exhibits a characteristic (SUPERSEDED: 66 FR 27266; 5/16/01; SEE ALSO RPC# 11/4/92-01). The treatment of nonhazardous or characteristic electroplating wastewater can generate a listed F006 sludge, whether treatment occurs at generator facility or off-site TSDF.
 
07/01/1989CLARIFICATION OF THE F009 LISTINGQuestion & Answer
 Description: The F009 listing applies only to spent cleaning and stripping baths from electroplating processes that are used after the cyanide bath, because these baths contain cyanide due to dragout (SEE ALSO: RPC# 7/12/94-01).
 
06/28/1989SOLVENT AND COMMERCIAL CHEMICAL PRODUCT WASTE STREAMSMemo
 Description: A listed solvent used to extract aqueous liquid from a product stream meets a listing when it is spent and removed from the process. An extracted aqueous wastestream which picked up trace amounts of solvent during extraction is not F001-F005. A chemical made in a lab instead of purchased from a commercial source is equivalent to a CCP and could be P-listed or U-listed when disposed. Diluting a CCP to make a lab standard is not "use" and excess diluted CCPs that are not analyzed can meet a P or U listing.
 
04/26/1989RECYCLING OF ELECTROPLATING SLUDGES (F006) FOR CEMENT/AGGREGATE MANUFACTUREMemo
 Description: Discussion of sham recycling. Lists criteria to be used in deciding whether processing of secondary material is legitimate recycling or regulated hazardous waste treatment and sham recycling. Cement kiln dust (CKD) generated when F006 is used as ingredient is only exempt if CKD chemical makeup is not significantly affected by the use of hazardous waste (SUPERSEDED: see 266.112). F006 destined for use as ingredient in aggregate, cement, or other products to be placed on the land is regulated as a hazardous waste from the point of generation forward until 266.20(b) is satisfied. Smelting or recovering metals from F006 is not subject to regulation (SEE ALSO: Part 266, Subpart H). Smelter slag residue from F006 metal recovery is hazardous waste via derived-from rule (SEE ALSO: 261.3(c)(2)(ii), 266.20(c), and 59 FR 67256; 12/29/94).
 
04/19/1989GENERATOR TREATMENT OF F006 ELECTROPLATING SLUDGEMemo
 Description: Stabilizing F006 compounds prior to thermal drying is hazardous waste treatment. A permit is not needed if the unit is exempt under 270.1(c)(2) or if treatment occurs in generator accumulation units in compliance with 262.34. A permit is required if thermal treatment of hazardous waste is involved.
 
04/14/1989PLASTIC PACKING MEDIA FROM AIR STRIPPING TOWER TREATING CONTAMINATED GROUNDWATERMemo
 Description: Volatilization qualifies as treatment. Filter material used in the treatment of F001-contaminated groundwater is subject to regulation since media contains F001 under the contained-in policy. The derived-from rule does not apply and delisting is not needed, but media must be handled as hazardous waste until handler demonstrates that it no longer contains F001.
 
04/12/1989WASTE SOLVENT-BASED GLUEMemo
 Description: A solvent used as an ingredient is not an F001-F005 spent solvent. A waste glue with a solvent ingredient is not listed.
 
03/01/1989DEFINITION OF SPENT SOLVENT Question & Answer
 Description: Cutting oil containing 80 percent 1,1,1-trichloroethane, before use, is not F002 when spent. 1,1,1-trichloroethane is used as an ingredient, which is not a use covered by the F001-F005 spent solvent listings.
 
03/01/1989SPENT SOLVENTS IN SCINTILLATION COCKTAILSQuestion & Answer

01/24/1989REGULATORY STATUS OF WASTEWATER TREATMENT SLUDGES FROM ZIRCONIUM PHOSPHATING OF ALUMINUM CANSMemo
 Description: Wastewater treatment sludges from processes involving zirconium phosphating of aluminum cans should be excluded from F019. EPA plans to modify the F019 listing to exclude these wastes. The exclusion would apply retroactively to wastes generated before promulgation of the final exclusion.
 
01/01/1989REGULATORY STATUS OF WASTEWATER TREATMENT SLUDGES FROM ZIRCONIUM PHOSPHATING OF ALUMINUM CANSMemo
 Description: Wastewater treatment sludges from zirconium phosphating of aluminum cans do not contain or form Appendix VIII constituents in hazardous concentrations and should not be hazardous waste. Proposes modifying the F019 listing (SEE ALSO: 55 FR 5340; 2/14/90).
 
12/07/1988INDUSTRIAL PLATING OPERATIONS, STATUS OF VARIOUS WASTES FROMMemo
 Description: Electroless plating is not electroplating. A facility with a recycling unit needs a permit only for hazardous waste storage prior to or after recycling unless the reclamation process involves incineration or land disposal. Partially reclaimed waste which only needs further refining before it can be beneficially used may not be a waste. Partially reclaimed material may be eligible for a variance. Discussion of the regulatory status of filter cake from treatment of plating wastes. Filter cake from thre treatment of an electroplating bath is more likely to be a spent material than a sludge (i.e., plating bath is not wastewater).
 
12/06/1988SOLVENT-CONTAMINATED WASTESTREAMS FROM A PHARMACEUTICAL MANUFACTURER; SOLVENT-CONTAMINATED WASTESTREAMS FROM PHARMACEUTICAL MANUFACTURERMemo
 Description: F001-F005 solvents used as carriers, extractants, etc. are listed hazardous waste when separated from the process in which they were used, but other wastestreams (extracted wastewaters, etc.) that picked up trace solvents during process (carryover) are not F001-F005 or listed via mixture rule once separated from process. Rinsewaters with solvent from equipment rinsing are not listed solvents. Solvents used as ingredients or reactants incorporated into products are not used as solvents and do not trigger F listings.
 
11/16/1988CASE-BY-CASE EXTENSIONS OF LAND DISPOSAL RESTRICTIONS EFFECTIVE DATESMemo
 Description: EPA is aware of special problems in storing dioxin-containing wastes since no facilities are permitted to treat or dispose of these wastes. Discussion of notice of information needed to process case-by-case extension application.
 
10/27/1988TREATMENT RESIDUALS OF CHARACTERISTIC HAZARDOUS WASTE AS A LISTED HAZARDOUS WASTEMemo
 Description: A sludge is F006 once it precipitates from an electroplating wastewater, whether at generator site or at off-site TSDF. Discussion of the derived-from rule for characteristic waste and waste listed solely for characteristic (SUPERSEDED: See RPC# 7/5/89-01; SEE ALSO: 66 FR 27266; 5/16/01). A generator is not required to identify the source of nonhazardous wastewater, but the TSDF responsible for assigning F006 to sludges. For improper waste characterization, correct the error on the manifest or reject the shipment. The generator and TSDF are potentially liable.
 
10/03/1988IMMERSION PLATING WASTEWATERS-BRONZE PLATINGMemo
 Description: The plating of copper-tin (bronze) alloy on carbon steel wire using no electrodes or electrolysis is "immersion plating" and is not electroplating operation triggering F006-F009 listings.
 
09/01/1988STILL BOTTOM WASTE GENERATED DURING THE PRODUCTION OF POLYSTYRENEMemo
 Description: Toluene used as a carrier or diluent during the production of polystyrene is used as a solvent. Still bottoms from the recovery of spent toluene are F005, even if they are generated in a closed-loop recycling process.
 
08/29/1988PENTACHLOROPHENOL AS A WOOD PRESERVATIVEMemo
 Description: EPA is considering a petition to change the designation of pentachlorophenol (PCP)-containing wastes F021 and F027 from acutely hazardous to toxic. The banning of chemicals is outside the purview of the Office of Solid Waste.

 Description: Filters from paint spray booths are not listed hazardous waste, although they may exhibit characteristics (does not address filters capturing solvents used to clean booths). if F001-F005 solvent is used to clean paint-laden filter, the resulting solution of paint and thinner is a listed hazardous waste.
 
07/21/1988CHLOROFLUOROCARBON RECYCLINGMemo
 Description: Used refrigerants meet the definition of a spent material. Used CFC refrigerant is not F-listed spent solvent but may exhibit a characteristic. Used refrigerant is not U121 or U075 because it has been used. The P-listings and U-listings do not apply to used chemicals. Cylinders containing used refrigerants to be reclaimed are solid waste (SW). Generators may use knowledge of similar operations at different facilities to characterize waste (SEE ALSO: 261.4(b)(12)). An owner of refrigeration equipment and a company or individual performing servicing may be generators of used refrigerant waste (i.e., cogenerators).
 
05/13/1988INTERPRETATION OF 40 CFR 268.7 REQUIREMENTSMemo
 Description: Listings depend on how materials are used in a process, not only on the hazardous constituents. Restricted wastes that are treated, stored, disposed on site or sent off site are subject to the testing, recordkeeping, and manifest requirements.

04/14/1988APPLICABILITY OF SOLVENT AND ELECTROPLATING LISTINGSMemo
 Description: Discarded paint, residues (scrubber water) with a solvent ingredient are not F-listed, but may be characteristic. Paint stripper is a solvent use. A sludge from metal cleaning wastewater associated with electroplating is F006. Routine cleaning, stripping not normally associated with electroplating. The purpose of cleaning, not the location, determines if associated. Metal stripping is part of electroplating. Stripped paint waste listed solely for a characteristic (F003) mixed with a solid waste is hazardous only if it is characteristic (SEE ALSO: 66 FR 27266; 5/16/01). Discussion of mixture rule wastewater exclusions (SEE: 261.3(a)(2)(iv)). F007-F009 are for cyanide electroplating solutions or where cyanides are used in the process. A spent stripping bath itself might also be F001-F005. The scale and size of aluminum chemical conversion coating operation does not affect F019.

04/01/1988DILUTION OF LAND DISPOSAL RESTRICTED WASTEQuestion & Answer
 Description: The dilution prohibition does not affect other regulatory provisions which may allow dilution. The mixing of F003 with a nonhazardous wastes in order to render it nonhazardous is a legitimate treatment. The dilution prohibition does not allow mixing as a substitute for adequate treatment (SEE ALSO: 57 FR 37210; 8/18/92).
 
04/01/1988HAZARDOUS WASTE I.D.Question & Answer
 Description: Groundwater contaminated with F001-F005 solvents is subject to Subtitle C because it contains a listed waste per the contained-in policy. If the groundwater is treated such that it no longer contains a hazardous waste, or the solvents in the groundwater are delisted, it is no longer subject to Subtitle C (SEE ALSO: 61 FR 18779; 4/29/96; 66 FR 27266; 5/16/01).
 
04/01/1988SPENT SOLVENT LISTINGSQuestion & Answer
 Description: Cutting oil containing, before use, 80 percent 1,1,1-trichloroethane and 20 percent lubricating oil is F002 when spent because 1,1,1-trichloroethane is used a a diluent for mobilizing constituents in lubricating oil (SUPERSEDED: See RPC# 3/1/89-02).
