In 1946, the California Legislature enacted the first air pollution control
law authorizing the formation of county air pollution control districts.
Los Angeles
County opened the first air pollution control office in early 1947 and Santa Clara
County followed soon after.

By 1950, it was evident that pollution overflowed political boundaries, and that a
single-county district was not the answer for the Bay Area. In 1955, the Bay Area Air
Pollution Control Law was adopted, establishing the Bay Area Air Pollution Control
District as the first regional air pollution control agency in the nation.

1959

The Motor Vehicle Pollution Control Board (MVPCB) is established by the state of
California, later renamed the California Air Resources Board (ARB).
