§ 40200 Bay Area Air District

• •There's a special group called the Bay Area Air Quality Management District that watches over the air in certain parts of California.
• •This group used to be called the Bay Area Air Pollution Control District, but now it has a new name.
• •It covers these counties: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, and Santa Clara, plus parts of Solano and Sonoma.
• •If you see the old name in any rules or papers, it means the same thing as the new name.

You live in San Francisco and hear about rules to keep the air clean.

The Bay Area Air Quality Management District is the group making those rules for your area. Even if someone calls it the old name, they mean the same group.
