The Resource Conservation and Recovery Act of 1976, as amended (RCRA), authorizes the United States Environmental Protection Agency (EPA) to grant approval to states to operate their underground storage tank programs in lieu of the federal program. The EPA codifies its decision to approve state underground storage tank programs and incorporate by reference those provisions of the state statutes and regulations that EPA has approved. This action codifies the prior approval of South Carolina's underground storage tank program, which EPA approved on August 28, 2002, and incorporates by reference approved provisions of South Carolina's statutes and regulations.
