Public comment period opens for the TFCA Policies Commencing FYE 2027
The Air District is currently accepting public comments for the TFCA Policies. For the first time, these Policies will guide the use of both the 60 Percent Fund that is administered by the Air District, and the 40 Percent Fund, which is passed through and administered by the designated public agency in each of the nine Bay Area counties (collectively referred to as the “administering agencies”). Based on input from stakeholders, Air District staff will prepare a final draft of the proposed updates to the Policies for consideration by the Air District’s Board of Directors at a meeting that is tentatively scheduled for October 2025. The adopted Policies will govern the use of the TFCA Funds starting from July 1, 2026, for a year or more.
Webinar
Interested parties are strongly encouraged to view the webinar before submitting comments.
A webinar has been scheduled to provide background on the TFCA program, discuss the proposed updates, review the public comment process and the timeline, and obtain stakeholder feedback.
Please note that registration is required for participation in the webinar and early registration is encouraged.
- July 30, 2025 from 11AM to 12PM PT (register)
