Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, San Diego Air Pollution Control District

EPA is taking direct final action on a revision to the California State Implementation Plan. The revision concerns a rule from the San Diego Air Pollution Control District (SDAPCD). This approval action will incorporate this rule into the federally approved SIP. The intended effect of approving this rule 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 rule controls VOC emissions from organic solvents. Thus, EPA is finalizing the approval of this revision 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.
