The Air District’s Board of Directors approved the proposed updates to the Transportation Fund for Clean Air Regional Fund Policies for Fiscal Year Ending 2020 on June 5, 2019.

New: FYE 2020 TFCA Regional Fund Policies and Evaluation Criteria

On June 5, 2019, following a public comment period, the Air District's Board of Directors approved proposed updates to the Transportation Fund for Clean Air (TFCA) Regional Fund Policies and Evaluation Criteria for Fiscal Year Ending (FYE) 2020. A copy of the approved policies can be downloaded from the “Resources” section below. Funding opportunities for the FYE 2020 cycle will be announced later this summer.

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. 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. Sixty percent of TFCA funds are awarded by the Air District through the TFCA Regional Fund to eligible programs implemented directly by the Air District, referred as Air District-sponsored programs.


Each year, the Air District's Board of Directors approves the allocation of new TFCA funds for the eligible project categories and the updates to the policies that govern the use of the funds through the TFCA Regional Fund. On April 3, 2019, the Board approved the allocation of $14 million in new TFCA revenue that will be available in FYE 2020. On June 5, 2019, the Board approved updates to the policies for FYE 2020.

TFCA funds are made available by the Air District through grant programs on a first-come, first-served or competitive basis. While public agencies are eligible to apply to all TFCA grant programs, private entities are eligible to apply for only vehicle-based TFCA project funding.  

Eligible project categories include:

  • Trip reduction (for public agencies only) – the operation of commuter shuttle and ridesharing services, and pilot trip reduction projects.
  • Clean air vehicles and infrastructure (for all entities) – the purchase or lease of new alternative fuel vehicles and the installation or construction of alternative fuel infrastructure.
  • Bicycle facilities (for public agencies only) - the construction of new bikeways, and the installation of new bike parking facilities, e.g., lockers and racks.

TFCA projects are evaluated on the basis of their effectiveness at reducing criteria pollutant emissions from on-road mobile sources and other criteria described in the application guidance released when a TFCA grant program is open to accept applications for a project category. TFCA funded projects are required to undergo a fiscal audit following completion. Reports on project effectiveness and the audit results are reviewed annually by the Air District’s Board of Directors and made available to the public.

 How to Apply

Solicitations for each project category are issued in phases throughout the year and may be either competitive or non-competitive (first-come, first-served). Guidance and application materials for each project category are available via the webpage links shown below:
