Summary

The Environmental Protection Agency (EPA) is proposing to approve portions of three state implementation plan (SIP) revisions submitted by the State of California to meet Clean Air Act (CAA or "the Act") requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS or "standards") in the San Joaquin Valley, California ozone nonattainment area. First, the EPA is proposing to approve the portions of the 2016 Ozone Plan for the 2008 8-Hour Ozone Standard ("2016 Ozone Plan") that address the requirements to demonstrate attainment by the applicable attainment date and implementation of reasonably available control measures, among other requirements. Second, the EPA is proposing to approve the portions of the Revised Proposed 2016 State Strategy for the State Implementation Plan ("2016 State Strategy") related to the ozone control strategy for San Joaquin Valley for the 2008 ozone standards, including a specific aggregate emissions reduction commitment. Lastly, the EPA is proposing to approve an air district rule addressing the emission statement requirement for ozone nonattainment areas. The EPA is not taking action at this time on the portions of the San Joaquin Valley 2016 Ozone Plan that address the requirements for a reasonable further progress (RFP) demonstration, motor vehicle emissions budgets (MVEBs), a base year emissions inventory, and contingency measures for failure to attain or to meet reasonable further progress milestones. We intend to address these remaining elements in a forthcoming proposal.
