2022 State Strategy for the State Implementation Plan (2022 State SIP Strategy)
Categories
The federal Clean Air Act requires areas that exceed the health-based national ambient air quality standards to develop State Implementation Plans (SIP) that demonstrate how they will attain the standards by specified dates.
In 2015, the United States Environmental Protection Agency (U.S. EPA) strengthened the 8-hour ozone standard to 70 parts per billion (ppb). Nineteen areas in California were designated nonattainment in 2018. CARB will be considering regional SIPs for this standard in 2022. The 2022 State SIP Strategy includes measures and commitments to reduce emissions from State-regulated sources to support attainment of the 70 ppb standard in all nonattainment areas across California.

CARB is collaborating with local air districts on development of regional SIPs and solicited stakeholder input on the development of the 2022 State SIP Strategy. This included workshops and participation in local air district outreach efforts. CARB staff finalized the 2022 State SIP Strategy and Environmental Analysis and the Board adopted on September 22, 2022.
