EPA Partially Approves, Disapproves California's Air Quality Plan for San Joaquin Valley

The Environmental Protection Agency (EPA) has taken final action to partially approve and disapprove California's state implementation plan (SIP) revisions to address Clean Air Act (CAA) requirements for the 1997 annual fine particulate matter (PM 2.5) national ambient air quality standards (NAAQS) in the San Joaquin Valley PM 2.5 nonattainment area. The EPA approved the 2013 base year emissions inventories but disapproved other key elements of the plan.
