This rule codifies in the regulations the prior approval of North Dakota's underground storage tank program and incorporates by reference approved provisions of the State's regulations. The Environmental Protection Agency (EPA) uses the regulations entitled, "Approved Underground Storage Tank Programs," to provide notification of the approval status of State programs and to incorporate by reference into the Code of Federal Regulations (CFR) those provisions of the State's regulations that are approved and that the EPA will enforce under the Resource Conservation and Recovery Act (RCRA). The EPA previously provided notification and opportunity for comments on the Agency's decisions to approve the North Dakota underground storage tank program, and the EPA is not reopening the decisions, nor requesting comments, on the approval of the North Dakota program, as published in the Federal Register documents specified in Section I.C of this document.
