Clean Air Act Approval and Promulgation of Prevention of Significant Deterioration (PSD) and General Permitting Provisions Implementation Plan for Arizona State Pinal County Air Quality Control District

EPA is promulgating direct final approval of portions of a requested State Implementation Plan (SIP) revision submitted by the State of Arizona on behalf of Pinal County for the purpose of meeting requirements of the Clean Air Act, as amended in 1990 (CAA or the Act) with regard to general permitting and prevention of significant deterioration (PSD) programs in areas of Pinal County that are in attainment of the national ambient air quality standards (NAAQS). The requested revision was submitted by the State to satisfy certain Federal requirements for an approvable SIP. EPA is taking this action to approve the portions of Pinal's rules identified below into the SIP for the purpose of meeting the PSD and preconstruction permitting requirements of 40 CFR 51.160 through 51.164 and 51.166, under the authority granted by 40 CFR 51.105. Approval of Pinal's rules for the purposes of meeting the nonattainment preconstruction permitting requirements of 40 CFR 51.165 will take place under a separate action. This action does not in any way imply that Pinal's nonattainment permitting provisions meet the requirements of Sec. Sec. 171, 172, 173, 181, 182, 187, or 189 of the CAA. Failure on Pinal's part to submit rules which meet the requirements of 40 CFR 51.165 may trigger sanctions as provided for under Sec. 179 of the Clean Air Act.
