In 1970 California legislation was passed that placed the primary responsibility of controlling air pollution at the local level. Following this action, the San Luis Obispo County Board of Supervisors formed the APCD and became the APCD Board. In 1995, the APCD Board was expanded to include representation from all incorporated cities throughout the county. Today the APCD Board consists of twelve members, five County Supervisors and one city council member from each of the seven incorporated cities. The Board is the decision making body for the District and is responsible for adopting rules, setting policies and providing direction on important air quality issues impacting the county.
The San Luis Obispo APCD is one of 35 air districts located throughout California. Since air pollution does not recognize boundary lines, the air districts work collectively to develop a comprehensive approach to reduce air pollution in California. The California Air Pollution Control Officers Association is an organization that facilitates discussion among the network of air districts on critical air pollution issues facing the state. Many Air District employees are active members of the CAPCOA. Visit the California Air Resources Board website to learn more about the air pollution history of California.
