This page last reviewed March 6, 2014


On May 22, 2008, the Air Resources Board (ARB) approved the San Joaquin Valley Unified Air Pollution Control District’s (District) 2008 PM2.5 State Implementation Plan (Plan). The Plan sets out the strategy to attain the federal 1997 Annual PM2.5 standard by 2015. ARB amended the SJV 2008 annual PM2.5 Plan on April 28, 2011. The revisions updated the rulemaking calendar and  transportation conformity budgets, and revised reasonable further progress tables and associated reductions for contingency purposes. With these revisions, U.S. EPA approved the 2008 SJV PM2.5 Plan on November 9, 2011, except for the contingency measures. To resolve the contingency measure disapproval, the District adopted an update to the contingency measures on June 20, 2013. ARB approvedthis update on June 27, 2013.
