Background
AB 2766, chaptered in 1990, allows air districts to collect $4 on each annual vehicle registration within their borders, one potential use of these funds is to reduce emissions caused by mobile sources. Yolo-Solano AQMD uses a portion of this revenue for the Clean Air Funds, which seeks to enhance the power of each dollar by directing money to the most cost-effective, impactful projects.
Through separate legislation, the air district also receives AB 8 property tax revenue s in the northeastern portion of Solano County. The District uses a portion of these funds in the Clean Air Fund program in Solano County. Funding levels for the Clean Air Funds program can change each year.
Proposals can be made in one of four categories: clean technologies and low-emission vehicles; alternative transportation; transit; and public education. Yolo-Solano AQMD staff evaluates project proposals based on a number of criteria and makes recommendations to two Board committees: the Yolo Clean Air Funds Committee and the Solano Clean Air Funds Committee. Each committee makes funding recommendations to the full Board, with a final Board vote typically taking place in June. Funds are then allocated for the following fiscal year.
Applicants awarded Clean Air Funds are required to submit a progress report every 6 months of during implementation and a final report to the District one year after project completion.
