The Environmental Protection Agency (EPA) is proposing to approve in part and disapprove in part portions of a state implementation plan (SIP) revision submitted by the State of California to meet Clean Air Act (CAA or "Act") requirements for the 1997 annual fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or "standards") in the San Joaquin Valley PM<INF>2.5</INF> nonattainment area. Specifically, the EPA is proposing to approve the 2013 base year emissions inventories in the submitted SIP revisions. Because the area did not attain by the State's projected attainment date of December 31, 2020, the EPA is proposing to disapprove the attainment demonstration and related elements, including the comprehensive precursor demonstration, five percent annual emission reductions demonstration, best available control measures (BACM) demonstration, reasonable further progress (RFP) demonstration, quantitative milestone demonstration, and contingency measures. The EPA is also proposing to disapprove the motor vehicle emission budgets in the plan as not meeting the requirements of the CAA and EPA regulations.
