# Bay Area Air Quality Management District

The Bay Area Air District (BAAD), formerly Bay Area Air Quality Management District or BAAQMD, is a public agency that regulates the stationary sources of air pollution in the nine counties of California's San Francisco Bay Area: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, southwestern Solano, and southern Sonoma. The BAAD is governed by a 24-member Board of Directors composed of elected officials from each of the nine Bay Area counties. The board has the duty of adopting air pollution regulations for the district. It is one of 35 Air Quality Management Districts in California.
The District launched the now-current name and brand logo in January of 2025.

## History

The first meeting of the Bay Area Air Pollution Control District (as it was initially known) board of directors was on November 16, 1955, possessing the duty of regulating the sources of stationary air pollution in the San Francisco Bay Area, that is, most sources of air pollution with the exception of automobiles and aircraft.

Citizens wishing to use wood burning appliances during winter months now must check if a Spare the Air alert is in effect, which would prohibit residential wood burning, with certain exemptions.

## Governing board

The Air District's board of directors is made up of 24 locally appointed representatives from 9 Bay Area counties. Each county's population determines the number of representatives on the Board, as follows:
* < 300,000: 1 representative each (Marin and Napa)
* 300,000-750,000: 2 representatives each (Solano and Sonoma)
* 750,000-1,000,000: 3 representatives each (San Francisco and San Mateo)
* >1,000,000: 4 representatives each (Alameda, Contra Costa, and Santa Clara)
Board members are appointed by their County's Board of Supervisors and/or their County's City Selection Committee.
In addition, the Board has 12 standing committees on which the board members sit.

## Uses of data

BAAD oversees regional data on air pollution and has the authority to declare Spare the Air alerts, when residents should take extra precautions when going outside and may be prohibited from engaging in activities such as burning. 511 Contra Costa built an RSS feed using these data, and released an iPhone application to alert people with allergies or other environmental sensitivities about air quality alerts.
