Air Plan Approval; California; Eastern Kern Air Pollution Control District; Reclassification

Under the Clean Air Act, the Environmental Protection Agency (EPA) is granting a request by the State of California to reclassify the Eastern Kern County ("Eastern Kern") nonattainment area from "Moderate" to "Serious" for the 2008 ozone national ambient air quality standards (NAAQS). In connection with the reclassification, the EPA is establishing a deadline of no later than 12 months from the effective date of reclassification for submittal of revisions to the Eastern Kern portion of the California State Implementation Plan (SIP) to meet certain additional requirements for Serious ozone nonattainment areas. The EPA has already received SIP revision submittals addressing most of the additional SIP requirements.
