Though the San Joaquin Valley was initially classified as serious nonattainment for the 1997 8- hour ozone standard,the USEPA approved reclassification to extreme nonattainment in the a Federal Register on May 5,2010(effective June 4,2010). d The State 8-hour ozone standard was approved by the GARB on April 28,2005,and became effective May 17,2006. e On September 25,2008,the USEPA redesignated the San Joaquin Valley to attainment for the a PM10 National Ambient Air Quality Standard(NAAQS)and approved the PM10 Maintenance Plan. f The San Joaquin Valley is designated nonattainment for the 1997 PM2.5 federal standards.The USEPA designated the San Joaquin Valley as nonattainment for the 2006 PM2.5 NAAQS on November 13,2009(effective December 14,2009).

While all criteria pollutants are a concern of the SJVAPCD, a project's air quality impacts are considered significant if they would violate any of the state air quality standards. Ozone precursors, PM10 emissions,and toxic air contaminants are emphasized in the review of applications for an Authority to ConstrucvPermit to Operate. Federal and state air quality regulations also require regions designated as nonattainment to prepare plans that either demonstrate how the region will attain the standard or that demonstrate reasonable improvement in air quality conditions.As noted,the SJVAPCD is responsible for developing attainment plans for the SJVAB for inclusion in California's SIP. The SJVAPCD's primary means of implementing air quality plans is by adopting and enforcing rules and regulations. Stationary sources within the jurisdiction are regulated by the SJVAPCD's permit authority over such sources and through its (emir 5-26 0
