Transportation for Clean Air



In 1991, the California Legislature passed AB 434 and AB 414 which permitted the Bay Area Air Quality Management District (hereinafter the “Air District”) to collect a fee of up to $4 per vehicle per year for reducing air pollution from motor vehicles and for related planning and programs. This legislation requires the Air District to allocate 40% of the revenue to an overall program manager in each county. The overall program manager must be designated "by resolutions adopted by the county board of supervisors and the city councils of a majority of the cities representing a majority of the population." The Napa County Transportation and Planning Agency (NCTPA) is the designated Program Manager for Napa County.

NCTPA annually allocates funds generated under AB 434. The monies are placed into a fund known as Transportation Fund for Clean Air (TFCA). Projects must be beneficial to air quality and be cost effective. The BAAQMD is responsible for administering the Bay Area Regional TFCA program and partners with NCTPA to administer the 40% Program Manager TFCA Funds.
