Résumé
The Environmental Protection Agency (EPA) is taking final action to approve or conditionally approve portions of a state implementation plan (SIP) revision submitted by California to address Clean Air Act (CAA or "Act") requirements for the 2006 and 2012 fine particulate matter (PM 2.5 ) national ambient air quality standards (NAAQS or "standards") in the Los Angeles-South Coast Air Basin ("South Coast") PM 2.5 nonattainment area. Specifically, the EPA is approving all but the contingency measure element of the submitted SIP revision as meeting all applicable Moderate area requirements for the 2012 annual PM 2.5 NAAQS, and conditionally approving the contingency measure element as meeting both the Moderate area contingency measure requirement for the 2012 annual PM 2.5 NAAQS and the Serious area contingency measure requirement for the 2006 24-hour PM 2.5 NAAQS. In addition, the EPA is approving 2019 and 2022 motor vehicle emissions budgets for use in transportation conformity analyses for the 2012 annual PM 2.5 NAAQS. The EPA is also reclassifying the South Coast PM 2.5 nonattainment area, including reservation areas of Indian country and any other area of Indian country within it
