The Resource Conservation and Recovery Act of 1976, as amended (RCRA), authorizes the U.S. Environmental Protection Agency (EPA) to grant approval to states to operate their underground storage tank programs in lieu of the federal program. 40 CFR part 282 codifies EPA's decision to approve state programs and incorporates by reference those provisions of state statutes and regulations that will be subject to EPA's inspection and enforcement authorities under sections 9005 and 9006 of RCRA subtitle I and other applicable statutory and regulatory provisions. This rule codifies in part 282 the prior approval of North Dakota's underground storage tank program and incorporates by reference appropriate provisions of state statutes and regulations.
