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

EPA is taking direct final action on a revision to the California State Implementation Plan. The revision concerns a rule from the South Coast Air Quality Management District (SCAQMD). 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) and hydrogen sulfide (H<INF>2</INF>S) in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). The revised rule controls VOC and H<INF>2</INF>S emissions from refinery vacuum-producing devices or systems. 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. This direct final action will incorporate this rule into the federally approved SIP and also stop the sanctions and Federal Implementation Plan clocks, which were started on August 14, 1998 when EPA published a final limited disapproval of the State's submittal of a previous version of this Rule.
