Abstract
EPA is taking final action to approve a state implementation plan (SIP) revision submitted by the State of California to provide for attainment of the carbon monoxide (CO) national ambient air quality standards (NAAQS) in the Los Angeles-South Coast Air Basin Area (South Coast). EPA is approving the SIP revision under provisions of the Clean Air Act (CAA) regarding EPA action on SIP submittals, SIPs for national primary and secondary ambient air quality standards, and plan requirements for nonattainment areas. The demonstration of attainment in the SIP depends, in part, upon reductions from an enhanced inspection and maintenance (I/M) program for motor vehicles. Since EPA has previously granted interim approval to the California I/M program, the Agency is granting interim approval to the reasonable further progress and attainment demonstration portions of the plan.
