Summary

EPA is proposing to approve, or conditionally approve, all or 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 Ventura County, California (“Ventura County”) ozone nonattainment area. The two SIP revisions include the “Final 2016 Ventura County Air Quality Management Plan,” and the Ventura County portion of the “2018 Updates to the California State Implementation Plan.” In today's action, the EPA refers to these submittals collectively as the “2016 Ventura County Ozone SIP.” The 2016 Ventura County Ozone SIP addresses the nonattainment area requirements for the 2008 ozone NAAQS, including the requirements for an emissions inventory, attainment demonstration, reasonable further progress, reasonably available control measures, contingency measures, among others; and establishes motor vehicle emissions budgets. The EPA is proposing to approve the 2016 Ventura County Ozone SIP as meeting all the applicable ozone nonattainment area requirements except for the contingency measure requirement, for which the EPA is proposing conditional approval. In addition, the EPA is beginning the adequacy process for the 2020 motor vehicle emissions budgets in the 2016 Ventura County Air Quality Management Plan through this proposed rule.
