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.
 
01/01/2004APPLICATION OF LDR TO DELISTED WASTESMemo
 Description: A delisting only absolves the generator from the obligation of handling the waste as hazardous. If hazardous waste is granted a delisting prior to generation, LDR requirements would not apply. If waste is generated and subsequently delisted, the generator must comply with applicable Part 268 requirements before disposal. A generator may file petition for variance from Part 268 requirements.
 
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).
 
06/01/2002RCRA Hazardous Waste Delisting: The First 20 YearsPublication
 Description: This report documents an evaluation of the outcomes and impacts of the hazardous waste delisting program, conducted by the United States Environmental Protection Agency under the Resources Conservation and Recovery Act (RCRA). The report describes the rationale for conducting a program evaluation, the results and outcomes of the delisting program, and other findings and issues raised in this evaluation. This evaluation was undertaken as part of EPA's implementation of the Government Performance and Results Act (GPRA) of 1993. That statute requires federal agencies to include program evaluations in the strategic planning process.
 
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.
 
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.
