The Environmental Protection Agency (EPA) recently granted a request by the State of California to voluntarily reclassify the Coachella Valley nonattainment area from "Severe-15" to "Extreme" for the 1997 8-hour ozone national ambient air quality standards (NAAQS) under section 182(b)(3) of the Clean Air Act (CAA). In this action, the EPA is proposing a schedule for the State to submit an Extreme ozone nonattainment area plan and revised title V and new source review (NSR) rules. The EPA is proposing deadlines for submittal of those state implementation plan (SIP) revisions and for implementation of the related control requirements. Under the EPA's proposed schedule, California would be required to submit these elements no later than July 10, 2020 (12 months from the effective date of the area's reclassification). We are also clarifying some language related to tribal areas that was included in our reclassification rule.
