EPA is taking final action to approve state implementation plan (SIP) revisions submitted by the State of California to provide for attainment of the particulate matter (PM-10) national ambient air quality standards (NAAQS) in the Los Angeles-South Coast Air Basin and the Coachella Valley Area, and to establish emissions budgets for these areas for purposes of transportation conformity.
