Updated 4/19/2021


Public comment period is open for TFCA Regional Fund Policies for FYE 2022 until March 22, 2021. Webinars are scheduled for March 2 and March 9, 2021. 


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.

Public Comment Period Open for TFCA Regional Fund Policies for FYE 2022

Every fiscal year since the TFCA program began in 1991, the Air District has updated the TFCA Regional Fund Policies and Evaluation Criteria.

As an initial step to updating the policies for the next fiscal year, the Air District is currently accepting public comments for the development of the TFCA Regional Fund Policies and Evaluation Criteria for Fiscal Year Ending 2022 (“FYE 2022 Policies”). Based on input from stakeholders, Air District staff will prepare a final draft of the proposed FYE 2022 Policies for consideration by the Air District’s Board of Directors at a meeting that is tentatively scheduled for June 2021. The adopted FYE 2022 Policies will govern the use of the TFCA funds from July 1, 2021, through June 30, 2022.

The draft Policies and Evaluation Criteria for the FYE 2022 (with redlined changes from FYE 2021) is available in the “Resources” section below.


Interested parties are strongly encouraged to attend a webinar before submitting comments.

Two webinars have been scheduled to provide background on the TFCA program, review the current fiscal year policies, discuss initial proposed updates, review the public comment process and the timeline, and obtain stakeholder feedback.

Please note that registration is required for participation in the webinars and early registration is encouraged, as the webinars are held online and limited to 100 attendees.

  • Webinar 1: March 2, 2021, from 10 AM to 11 AM PST (Register)
  • Webinar 2: March 9, 2021, from 2 PM to 3 PM PST (Register)
