The Environmental Protection Agency (EPA) is proposing to approve most elements of the state implementation plan (SIP) revisions submitted by 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 standards (NAAQS or "standards") in the Plumas County Moderate PM<INF>2.5</INF> nonattainment area ("Portola nonattainment area"). The SIP revisions are the "Portola Fine Particulate Matter (PM<INF>2.5</INF>) Attainment Plan" submitted on February 28, 2017, and the 2019 and 2022 transportation conformity motor vehicle emission budgets ("budgets") submitted on December 20, 2017. We refer to these submittals collectively as the "Portola PM<INF>2.5</INF> Plan" or "Plan." The EPA is proposing to approve the following elements of the Portola PM<INF>2.5</INF> Plan: The 2013 base year emissions inventories, the reasonably available control measure/reasonably available control technology (RACM/RACT) demonstration, the attainment demonstration, the reasonable further progress (RFP) demonstration, the quantitative milestones, and the budgets for 2019 and 2021. The EPA is not proposing any action at this time on the contingency measures in the Portola PM<INF>2.5</INF> Plan.
