Air quality plans provide an overview of the region's air quality and identify the pollution-control measures needed to expeditiously attain and maintain air quality standards. The District's plans include the San Diego Regional Air Quality Strategy (RAQS), addressing State requirements, and the San Diego portion of the California State Implementation Plan (SIP), addressing federal requirements.
The District actively solicits participation in the RAQS development process through its public workshop and public notice process. Workshops are held to discuss proposed rules and their potential impact so that any necessary revisions can be made in the early stages. Public notices are published to advise the public of an upcoming action. Citizens are encouraged to review the proposed actions and submit their comments to the District. For more information regarding Governing Board meetings, please see Governing Board Agendas & Meetings.
2022 Regional Air Quality Strategy (RAQS)
Ozone is a ground-level air pollutant formed when emissions from motor vehicles, industrial plants, consumer products, and other sources interact under the influence of sunlight and heat. Ozone pollution levels have declined significantly in the region, however the region does not yet meet the state ozone standards.
To comply with State law, the District must prepare an updated State Ozone Attainment Plan ("Regional Air Quality Strategy" or RAQS) to identify possible new actions to further reduce emissions. Initially adopted in 1992, the RAQS identifies measures to reduce emissions from sources regulated by the District, primarily stationary sources such as industrial operations and manufacturing facilities. Last updated in 2016, the RAQS is periodically updated to reflect updated information on air quality, emission trends, and new feasible control measures.

The California Clean Air Act (CCAA) of 1988 requires the air districts to endeavor, achieve and maintain the state ambient air quality standards by the earliest practicable date and develop plans for attaining the state ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide standards.
In compliance with the CCAA, the San Diego County Air Pollution Control District prepared and submitted the 1991 Regional Air Quality Strategy (RAQS) to address San Diego County's nonattainment status for ozone. The RAQS is designed to make expeditious progress toward attaining the state ozone standard and contains preliminary implementation schedules for control programs on stationary sources, transportation, indirect sources, and a vehicle/fuels program.

Climate and Pollution
The U.S. Environmental Protection Agency (EPA) has established
National Ambient Air Quality Standards (NAAQS) for six criteria
pollutants, which are known to be harmful to human health and welfare.
These criteria pollutants are:
Carbon Monoxide (CO)
Nitrogen Dioxide (NO2)
Particulate Matter (PM)
Sulfur Oxides (SOx)
The federal Clean Air Act (CAA) requires plans which identify how nonattainment areas will attain and/or maintain the NAAQS. The CAA requires the EPA to review each plan, any plan revisions, and to approve the plan/revisions if consistent with the CAA. Key elements of these plans include emission inventories, emission control strategies and rules, air quality data analyses, modeling, air quality progress and attainment or maintenance demonstrations.
The San Diego County Air Pollution Control District (District) has prepared an Attainment Plan for San Diego County (Attainment Plan), demonstrating how the region will further reduce air pollutant emissions in order to attain the current National Ambient Air Quality Standards for ozone in the future. Approved by the District Board on October 14, 2020, and the California Air Resources Board on November 19, 2020, the plan was submitted by CARB on January 8, 2021 for EPA's consideration as a revision to the California State Implementation Plan (SIP) for attaining the ozone standards.
