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

EPA is taking direct final action on revisions to the California State Implementation Plan (SIP). The revisions concern rule rescissions from the South Coast Air Quality Management District (SCAQMD). This approval action will rescind these rules from the federally approved SIP. The intended effect of approving these rule rescissions is to update and clarify the State Implementation Plan in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). The rule rescissions consist of obsolete rules that have been superseded or removed from the SCAQMD's regulations. EPA is finalizing the approval of these rule rescissions from 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.
