The public comment period for TFCA Regional Fund Policies for FYE 2021 (“FYE 2021 Policies”) has closed. The Air District will review the comments received and prepare a draft of the FYE 2021 Policies to be presented to the Air District’s Board of Directors for consideration. Once approved, the FYE 2021 Policies will be available in the “Resources” section below.


Vehicle emissions contribute to unhealthy levels of ozone, also known as "smog," and particulate matter.

In the Bay Area, tailpipe emissions from the transportation sector account for approximately 40 percent of the criteria air pollutants and greenhouse gases, or GHGs, emitted. Significant emissions reductions from the on-road transportation sector are key to helping the Bay Area attain state and federal ambient air quality standards and GHG emission reduction targets.

In 1991, the California State Legislature authorized the Air District to impose a $4 surcharge on cars and trucks registered within the Air District’s jurisdiction to provide grant funding to eligible projects that reduce on-road motor vehicle emissions. The statutory authority for the Transportation Fund for Clean Air, or TFCA, and requirements of the program are set forth in California Health and Safety Code Sections 44241 and 44242. 

Sixty percent of TFCA funds are awarded by the Air District through the TFCA Regional Fund, and to eligible programs implemented directly by the Air District, referred as Air District-sponsored programs. Each year, the Air District’s Board of Directors considers the allocation of new TFCA funds and the proposed updates to the policies. Solicitations and Call for Projects are issued following the Board’s approval.

The remaining forty percent of this funding is passed through to the designated agencies of the nine Bay Area counties through the County Program Manager Fund and is awarded by these agencies to TFCA-eligible projects located within those counties.

TFCA Regional Fund Policies for FYE 2021

Every fiscal year since the TFCA program began in 1991, the Air District has updated the TFCA Regional Fund Policies and Evaluation Criteria. The Air District is currently reviewing public comments received and developing a final draft of the TFCA Regional Fund Policies and Evaluation Criteria for Fiscal Year Ending 2021, or “FYE 2021 Policies.”

Air District staff will bring the final draft of the proposed FYE 2021 Policies for consideration by the Air District’s Board of Directors at a meeting that is tentatively scheduled for June 2020. The adopted FYE 2021 Policies will govern the use of the TFCA funds from July 1, 2020 through June 30, 2021.

The draft revisions to FYE 2020 Policies and Evaluation Criteria for FYE 2021 that were released for public input earlier this year are available in the “Resources” section below.

Board Approved TFCA Regional Fund Policies and Evaluation Criteria for FYE 2020

On June 5, 2019, following a public comment period, the Air District's Board of Directors approved proposed updates to the TFCA Regional Fund Policies and Evaluation Criteria for FYE 2020. A copy of the approved policies can be downloaded from the “Resources” section below.
