On October 1, 2015, the U.S. Environmental Protection Agency (EPA) strengthened the National Ambient Air Quality Standards (NAAQS) for ground-level ozone, lowering the primary and secondary ozone standard levels to 70 parts per billion (ppb). The South Coast Air Basin is classified as an “extreme” non-attainment area and the Coachella Valley is classified as a “severe-15” non-attainment area for the 2015 Ozone NAAQS. The 2022 AQMP will be developed to address the requirements for meeting this standard.
