EPA Proposes Approval of California's Plan to Address PM2.5 NAAQS in Los Angeles-South Coast Air Basin

The Environmental Protection Agency (EPA) is proposing to approve California's state implementation plan (SIP) revisions to address Clean Air Act requirements for the 2006 24-hour fine particulate matter (PM 2.5) national ambient air quality standards (NAAQS) in the Los Angeles-South Coast Air Basin, and to reclassify the area as a Serious nonattainment area due to its inability to meet the standard by the applicable attainment date.
