The Environmental Protection Agency (EPA) (also, "the Agency" in this preamble) is granting a petition submitted by Sandvik Special Metals (Sandvik), in Kennewick, Washington to exclude (or "delist") up to 1,500 cubic yards of F006 wastewater treatment sludge per year from the list of Federal hazardous wastes. The EPA has decided to grant the petition based on an evaluation of waste-specific information provided by Sandvik and a consideration of public comments received. This action conditionally excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when disposed of in a Subtitle D landfill permitted, licensed, or registered by a State. The rule also imposes testing conditions for waste generated in the future to ensure that this waste continues to qualify for delisting. Subject to state- only requirements within the State of Washington, or federally- authorized or state-only requirements in other states where the subject wastes may be disposed of, Sandvik's petitioned waste may be disposed of in a Subtitle D landfill which is permitted, licensed, or registered by a State to manage municipal solid waste, or non-municipal non- hazardous waste.
