The Environmental Protection Agency (EPA) is granting a petition submitted by Samsung Austin Semiconductor (Samsung) to exclude from hazardous waste control (or delist) a certain solid waste. This final rule responds to the petition submitted by Samsung to have the copper filter cake from the electroplating process excluded, or delisted from the definition of a hazardous waste. The Copper filter cake is listed as F006, wastewater treatment sludges from electroplating operations. The basis of the listing is cadmium, hexavalent chromium, nickel, and cyanide (complexed). After careful analysis and evaluation of comments submitted by the public, the EPA has concluded that the petitioned wastes are not hazardous waste when disposed of in Subtitle D landfills. This exclusion applies to the copper filter cake generated at Samsung Austin Semiconductor's Austin, Texas facility. Accordingly, this final rule excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when disposed of in Subtitle D landfills, but imposes testing conditions to ensure that the future-generated wastes remain qualified for delisting.
