Board Members and Duties (AB 423)

California Assembly Bill AB 423

California Assembly Bill 423 (Gloria, 2019) amended State law to restructure and expand the governing board of the San Diego County Air Pollution Control District. AB 423 adds specified duties to the District and requires the California Air Resources Board (ARB) to conduct a program audit of the District.  The District's goal is to comply with AB 423 while aligning services to available resources to maintain fiscal stability.  More information on the new State requirements is provided below.


Since 1955, the 5-member County of San Diego Board of Supervisors has served as the District's governing board, known as the Air Pollution Control Board.  As of March 1, 2021, AB 423 requires the appointment of a new 11-member governing board consisting of:
