The Environmental Protection Agency (EPA or ``Agency'') proposes to approve portions of two state implementation plan (SIP) revisions submitted by the State of California to meet 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 San Joaquin Valley (SJV) Serious nonattainment area. Specifically, the EPA proposes to approve the State's Serious area plan for the 2012 annual PM<INF>2.5</INF> NAAQS, submitted May 10, 2019, for all Serious PM<INF>2.5</INF> area requirements (except contingency measures), including emissions inventories, best available control measures, demonstrations of attainment and reasonable further progress, quantitative milestones, and motor vehicle emission budgets. We may, however, reconsider this proposal if, based on new information or public comments, we find that the State has not satisfied the statutory criteria for a Serious area PM<INF>2.5</INF> attainment plan. The EPA also proposes to disapprove the portions of the State's Serious area plan, and the contingency provisions of a third SIP submission regarding residential wood burning, that pertain to the Serious area contingency measurement requirements for the 2012 annual PM<INF>2.5</INF> NAAQS.
