Clean Air Act Approval and Promulgation of Emission Reduction Credit Banking Provisions; Implementation Plan for California State Mojave Desert Air Quality Management District

EPA is taking direct final action on revisions to the California State Implementation Plan (SIP). The revisions concern rules from the Mojave Desert Air Quality Management District (MDAQMD or the District). This approval action will incorporate these rules into the federally approved SIP. The intended effect of approving these rules is to control air pollution in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act) with regard to new source review (NSR) in areas of MDAQMD that are not in attainment of the national ambient air quality standards (NAAQS). Thus, EPA is finalizing the approval of these revisions into the California SIP under provisions of the CAA regarding EPA action on SIP submittals, SIPs for national primary and secondary ambient air quality standards and plan requirements for nonattainment areas.
