## Abstract

EPA today approves the State Implementation Plan (SIP) submitted by the State of California for the purpose of bringing about attainment in the Mammoth Lakes Planning Area (MLPA) of the national ambient air quality standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM<INF>10). The ``moderate'' area SIP was submitted by the State to satisfy certain Federal requirements in the Clean Air Act for an approvable nonattainment area PM<INF>10 plan for the MLPA. The intended effect of approving this plan is to regulate emissions of PM<INF>10 in accordance with the requirements of the CAA, as amended in 1990.
