Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision; South Coast Air Quality Management District

EPA is taking direct final action to approve revisions to the California State Implementation Plan (SIP). The revisions concern rules from the South Coast Air Quality Management District (SCAQMD). These revisions concern the New Source Review requirements and the methodology for calculating facility allocations for oxides of nitrogen (NO<INF>X</INF>) and oxides of sulfur (SO<INF>X</INF>) for sources subject to the Regional Clean Air Incentives Market (RECLAIM) program in the SCAQMD. This approval action will incorporate these rules into the Federally approved SIP. The intended effect of approving these rules is to regulate the construction and modification of stationary sources and the calculation of RECLAIM facility allocations in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). 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 permitting in nonattainment areas.
