The Environmental Protection Agency (EPA, also the Agency or we in this preamble) today is granting a petition submitted by the Southeastern Public Service Authority (SPSA) and Onyx Environmental Services (Onyx) to exclude (or delist), on a one-time basis, a combustion ash from the lists of hazardous wastes. After careful analysis, we have concluded that the petitioned waste does not present an unacceptable risk when disposed of in a Subtitle D (nonhazardous waste) landfill. This exclusion applies to combustion ash previously generated at the SPSA Power Plant in Portsmouth, Virginia, which is currently located at the SPSA Regional Landfill in Suffolk, Virginia. Accordingly, this final rule conditionally excludes a specific volume of the petitioned waste from the requirements of the hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when the petitioned waste is disposed of in a Subtitle D landfill which is permitted, licensed, or registered by a State to manage municipal or industrial solid waste.
