2007 Ozone SIPs for Northern California

Resources

Planning Links

This page updated December 2, 2004.

In July 1997, U.S. EPA established a new federal 8-hour standard for ozone of 0.085 parts per million.  U.S. EPA designated fifteen areas in California that violate the federal 8-hour ozone standard on April 15, 2004.  Each nonattainment areas' classification and attainment deadline is based on the severity of its ozone problem.  Northern California nonattainment areas and attainment deadlines are:  San Joaquin Valley (2013), Sacramento Region (2013), San Francisco Bay Area (2007), Eastern Kern County (2009 - 2014), Western Nevada County (2009 - 2014), Central Mountain Counties (Amador and Calaveras) (2009 - 2014), Southern Mountain Counties (Tuolumne and Mariposa) (2009 - 2014), Butte County (2009 - 2014), and the Sutter Buttes (2009 - 2014).
SIPs demonstrating attainment of the new federal ozone standard must be adopted by the local air districts and ARB, and submitted to U.S. EPA by June 15, 2007.  ARB, air districts, and other key stakeholders are coordinating development of local SIPs through the Northern California 8-Hour Ozone SIP Working Group.  The Working Group provides a forum for the sharing of technical information and for ensuring that each area's SIP is consistent with attainment throughout the region.
