California Air Resources Board

CARB and the San Joaquin Valley Air Pollution Control District (District) developed the 2018 Plan for the 1997, 2006, and 2012 PM2.5 Standards (2018 PM2.5 Plan) to meet nonattainment area requirements under the Clean Air Act for multiple federal National Ambient Air Quality Standards for fine particulate matter (PM2.5): the 65 micrograms per cubic meter (μg/m3) 24-hour and 15 μg/m3 annual standards, the 35 μg/m3 24-hour standard, and the 12 μg/m3 annual standard. The 2018 PM2.5 Plan includes a strategy to provide for attainment of the four standards throughout the San Joaquin Valley. CARB adopted the 2018 PM2.5 Plan on January 24, 2019. This page provides links to documentation relevant to the 2018 PM2.5 Plan. Additional documentation will be posted here as it becomes available.
