Abstract
The Environmental Protection Agency (EPA) is taking final action to approve a state implementation plan (SIP) revision submitted by the State of California to address Clean Air Act (CAA or "Act") requirements for the 2012 annual fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standard (NAAQS or "standard") in the Plumas County Moderate PM<INF>2.5</INF> nonattainment area ("Portola nonattainment area"). The submitted SIP revision is the State's "Proposed Portola PM<INF>2.5</INF> Plan Contingency Measure SIP Submittal" ("PM<INF>2.5</INF> Plan Revision"), which includes a revised City of Portola ordinance regulating PM<INF>2.5</INF> emission sources and the State's demonstration that this submission meets the Moderate area contingency measure requirement for the 2012 annual PM<INF>2.5</INF> NAAQS in the Portola nonattainment area. The EPA is also taking final action to approve the contingency measure element of the Moderate area attainment plan for the Portola nonattainment area, as revised and supplemented by the PM<INF>2.5</INF> Plan Revision.
