Withdrawal of Approval of Air Quality Implementation Plans and Findings of Failure To Submit Required Plans; California; San Joaquin Valley; 1-Hour and 8-Hour Ozone Extreme Area Plan Elements

摘要

EPA is withdrawing its March 8, 2010 final action approving State Implementation Plan (SIP) revisions submitted by California to provide for attainment of the 1-hour ozone National Ambient Air Quality Standards (NAAQS) in the San Joaquin Valley extreme ozone nonattainment area. In addition, EPA is withdrawing its March 1, 2012 determination that the California SIP satisfies the requirement regarding offsetting emissions growth caused by growth in vehicle miles traveled (VMT) under the Clean Air Act (CAA) for the 1997 8-hour ozone NAAQS in the San Joaquin Valley. Finally, EPA is finding that California has failed to submit required SIP revisions to provide for attainment of the 1-hour ozone NAAQS and to address the VMT emissions offset requirement for the 1997 8-hour ozone NAAQS in the San Joaquin Valley. Under the CAA, these findings of failure to submit trigger the 18-month time clock for mandatory imposition of sanctions and the two-year time clock for EPA to promulgate federal implementation plans.
