Approval and Promulgation of Air Quality Implementation Plans; State of California; Interstate Transport of Pollution; Interference With Prevention of Significant Deterioration Requirement

EPA is finalizing a limited approval and limited disapproval of a state implementation plan (SIP) revision submitted by the State of California on November 17, 2007, to address the "transport SIP" provisions of Clean Air Act (CAA) section 110(a)(2)(D)(i) for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and the 1997 fine particulate matter (PM<INF>2.5</INF>) NAAQS. Section 110(a)(2)(D)(i) of the CAA requires that each SIP contain, among other things, adequate measures prohibiting emissions of air pollutants in amounts which will interfere with any other State's measures required under title I, part C of the CAA to prevent significant deterioration of air quality. EPA is approving California's SIP revision with respect to those Districts that implement SIP- approved permit programs meeting the approval criteria and simultaneously disapproving California's SIP revision with respect to those Districts that do not implement SIP-approved permit programs meeting the approval criteria, as discussed in our May 31, 2011 proposed rule (76 FR 31263).
