On January 24, 2019, the California Air Resources Board adopted the 2018 Plan for the 1997, 2006, and 2012 PM2.5 Standards (2018 PM2.5 Plan) for the San Joaquin Valley. The 2018 PM2.5 Plan addresses multiple federal PM2.5 ambient air quality standards. On May 28, 2020, CARB will consider a revision to the California SIP to revise an emissions reductions commitment in the 2012 PM2.5 Plan to support U.S. EPA’s evaluation of the 2018 PM2.5 Plan.
This page provides links to documentation relevant to the 2018 PM2.5 Plan. Additional CARB and District documentation will be posted here as they become available.
