The Environmental Protection Agency (EPA) is proposing to approve portions of two 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 portion of the "2016 Ozone Plan for the 2008 8-Hour Ozone Standard" ("2016 Ozone Plan") that addresses the requirement for a base year emissions inventory. Second, the EPA is proposing to approve the portions of the "2018 Updates to the California State Implementation Plan" ("2018 SIP Update") that address the requirements for a reasonable further progress (RFP) demonstration and motor vehicle emissions budgets (MVEBs) for the San Joaquin Valley for the 2008 ozone standards. Lastly, the EPA is proposing to conditionally approve portions of the 2018 SIP Update that address the requirement for contingency measures for failure to meet RFP milestones or to attain the NAAQS by the applicable attainment date. The proposed approval is conditional because it relies on commitments by the State air agency and regional air district to supplement the contingency measure portion of the 2018 SIP Update with submission of an additional contingency measure within one year of the EPA's final conditional approval.
