Under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is proposing to grant requests by the California Air Resources Board (CARB) to reclassify three nonattainment areas in California from "Moderate" to "Serious" for the 2015 ozone national ambient air quality standards (NAAQS). These three areas are herein referred to as the Eastern Kern, Sacramento Metro, and Western Nevada nonattainment areas. In connection with the reclassification, the EPA is proposing to establish deadlines for submittal of revisions to the Eastern Kern, Sacramento Metro, and Western Nevada portions of the California state implementation plan (SIP) to meet additional requirements for Serious ozone nonattainment areas.
