2007 San Joaquin Valley 8-hour Ozone Plan

This page last reviewed September 21, 2015

On October 22, 2015, the Air Resources Board (ARB) will conduct a public meeting to consider Updated Transportation Conformity Budgets for the San Joaquin 2008 Ozone, 2012 PM2.5, and 2008 PM10 State Implementation Plans (SIP).  If approved, ARB will submit the transportation conformity budgets to the U.S. Environmental Protection Agency (U.S. EPA) as a revision to the California SIP.

On June 14, 2007, the Air Resources Board (ARB) approved the San Joaquin Valley's (SJV) 2007 Ozone Plan. The plan sets out the strategy to attain the federal 1997 8-hour ozone standard by 2024. In September 2007, ARB strengthened the State's commitments to reduce emissions in the Valley in advance of the 2024 attainment date. ARB amended the SJV 2007 8-hour Ozone State Implementation Plan on July 21, 2011. The revisions updated the rulemaking calendar, updated transportation conformity budgets, and revised reasonable further progress tables and associated reductions for contingency purposes. With these revisions, U.S. EPA approved the 2007 SJV 8-hour Ozone Plan on March 1, 2012.

Below you will find links to the Valley's 2007 8-hour Ozone SIP Revisions, letters submitting the plan to U.S. Environmental Protection Agency, resolutions, and staff reports.
