Transportation Fund for Clean Air

TFCA Program Information

Read NVTA’s most recent TFCA Audit Report. 

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 administrator in each county. The county Program Administrator 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 Valley Transportation Authority (NVTA) is the designated Program Administrator for Napa County.

Annually, NVTA allocates the money generated under AB 434. The dollars are placed in the Transportation Fund for Clean Air (TFCA). Projects must be beneficial to air quality and be cost effective. The Air District is responsible for administering the TFCA Regional Fund program in the Bay Area and partners with NVTA to administer the remaining TFCA 40% Fund.

Program guidance and cost effectiveness requirements are updated annually. The Fiscal Year Ending 2025 program guidance can be viewed here: TFCA County Program Administrator Guidance FYE 2025
