## Abstract

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern the recision of rules from the San Luis Obispo County Air Pollution Control District (SLOCAPCD) and the South Coast Air Quality Management District (SCAQMD). The intended effect of this action is to bring the SLOCAPCD and the SCAQMD State Implementation Plans (SIP) up to date in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). EPA is finalizing the approval of these recisions 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.
