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

EPA is taking direct final action on revisions to the California State Implementation Plan (SIP.) These revisions concern rules from the following districts: the Mojave Desert Air Quality Management District (MDAQMD) and the South Coast Air Quality Management District (SCAQMD). This approval action will incorporate these rules into the federally approved SIP. The intended effect of approving these rules is to regulate emissions of volatile organic compounds (VOCs) in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). The revised rules control VOC emissions from wood product coating operations. 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.
