This direct final action, taken under the authority of the Clean Air Act (CAA or Act), corrects an error in previously promulgated rules approving certain elements of the North Carolina state implementation plan (SIP). The error relates to the North Carolina SIP's Motor Vehicle Emissions Control Standard rules and the correction removes a provision of the State's otherwise federally-enforceable regulations that could result in infringement upon the sovereign immunity of Federal facilities. The intended effect is to ensure that the North Carolina SIP is correctly identified in the applicable part of the Code of Federal Regulations and to eliminate the possibility of such infringement.
