Background 

### In December2012, the San Joaquin Valley Air Pollution Control District (District) adopted a SIP for the 35 ug/m3 24-hour PM2.5 standard (2012 PM2.5 Plan). The 2012 PM2.5 Plan was developed to meet requirements specified by the United States Environmental Protection Agency (U.S. EPA) PM2.5 Implementation Rule based on Subpart 1 provisions ofthefederal Clean AirAct (Act). In January 2013, ARB approved the 2012 PM2.5 Plan. In the time between the 2012 PM2.5 Plan adoption by the District in December2012 and the ARB hearing in January 2013, the D.C. Circuit Court determined that U.S. EPA erred in solely developing its implementation rule for PM2.5 underthe Subpart 1 general provision ofthe Act without considering the more specific particulate matter provisions in Subpart 4. The Court remanded the rule back to U.S. EPA to address the Subpart 4 provisions. During the January 2013 ARB hearing, the Board determined it was appropriate to approve the 2012 PM2.5 Plan at thattime and later provide any necessary supplemental information once U.S. EPA provided guidance in response to the D.C. Circuit Court decision.In 2014, U.S. EPA classified the San Joaquin Valley under Subpart 4 as a moderate nonattainment area forthe 35 ug/m3 24-hour PM2.5 standard and directed the State to submit a SIP bytlie end of2014 thatwould meetthe moderate area requirements. Also, U.S. EPA directed states to follow the existing guidance for PM1 0 SIP implementation under Subpart4. On September 18, 2014, the District adopted the "Supplemental Document: Clean Air Act Subpart 4: The 2012 PM2.5 Plan forthe 2006 PM2.5 StandardandDistrictRule 2201 (NewandModified StationarySource Review)" (Supplemental Document). The Supplemental Document demonstrates thatthe existing 2012 PM2.5 Plan satisfies the Subpart 4 requirements for a moderate PM2.5 nonattainment area. The Supplemental · Document also includes the District's request that the San Joaquin Valley be classified as a serious PM2.5 nonattainment area under Subpart 4 consistentwith the attainment demonstration in the 2012 PM2.5 Plan. The Supplemental Document provides the information U.S. EPA needs to approve the 2012 PM2.5 Plan under Subpart 4 consistent with the DC Circuit Court direction to U.S. EPA. PROPOSED ACTION Staff has reviewed the Supplemental Document and concluded that the 2012 PM2.5 Plan meets the requirements ofSubpart 4 ofthe Act for moderate PM2.5 nonattainment areas. Staff recommends thatthe Board approve the Supplemental Document and direct staffto submit itto U.S. EPA as a revision to the California SIP. Copies ofthe ARB staff report will be available on September 22, 2014. These may be obtained from ARB's Public Information Office, 1001 I Street, First Floor, Environmental Services Center, Sacramento, California, 95814, (916) 322-2990.
