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

EPA is taking direct final action granting limited approval and limited disapproval of revisions to the California State Implementation Plan (SIP). The revisions concern two rules from the South Coast Air Quality Management District (SCAQMD). This final action will incorporate these rules into the federally approved SIP. The intended effect of finalizing this action 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 rules control VOC emissions from active and inactive landfills. Thus, EPA is finalizing a simultaneous limited approval and limited disapproval of the rules under CAA provisions regarding EPA action on SIP submittals and general rulemaking authority because the rules, while strengthening the SIP, also do not fully meet the CAA provisions regarding plan submissions and plan requirements for nonattainment areas.
