Incentive Programs

There are a number of local and regional incentive programs available to agencies, businesses and consumers within the Yolo-Solano AQMD. Funding sources and timelines vary by program.

Local Programs

The Yolo-Solano AQMD administers the following incentive programs:

* Clean Air Funds

The Clean Air Funds Program allows private business, non-profit organizations and public agencies to apply for grants for projects designed to reduce emissions from motor vehicles. Projects awarded Clean Air Funds include replacing or retrofitting diesel trucks and off-road equipment that do not qualify for the regional programs, new electric vehicles, construction of pedestrian and bicycle facilities, transit projects and public information and education programs.
* AB 923 Programs

The Yolo-Solano AQMD previously ran the Clean School Bus Program. The district completed funding all qualifying retrofits and replacements in 2011-12. The Board of Directors will soon determine how additional AB 923 funds will be spent.

Regional Programs

Yolo-Solano AQMD also works to connect local businesses and public agencies with regional and statewide programs administered by the Sacramento Metropolitan AQMD and California Air Resources Board.

The regional air districts can help fleets pay for new lower emission engines, lower emission retrofits, and new equipment replacements under the AQMDs Heavy-Duty Low-Emission Vehicle Program. Private business and public agencies that use heavy-duty vehicles or mobile off-road equipment meeting specific cost-effective requirements can receive funds to defray the costs of new lower emission technologies for diesel engines. Our air quality incentive programs, administered by the SMAQMD to maximize efficiency, that are available to individuals, companies and agencies within the Yolo-Solano AQMD include the following:


The Carl Moyer Program funds eligible projects seeking to upgrade emission controls on heavy duty off-road vehicles including agricultural equipment (tractors, balers, irrigation pumps) and construction equipment (tractors, backhoes). See our Moyer Program page for more info.


* Moyer Voucher Incentive Program (VIP)

The Moyer Voucher Incentive Program (VIP) provides vouchers through AQMD-approved dealerships for the replacement of on-road heavy-duty diesel vehicles that have 2002 or older engines with cleaner emission vehicles. Applies to truck fleets with 3 or fewer vehicles that operated at least 75% in California in the past 24 months.

* Goods Movement Emission Reduction Program (GMERP)

Provides funds for vehicle replacements of Class 8 diesel on-road trucks. Applies to goods movement operation in California with at least 50 percent operation on trade corridor(s) in the past 24 months. (Note: this program is currently closed to new applications.)

Statewide Programs

The state currently funds substantial incentives for companies and agencies looking to transition their truck or bus fleet to hybrid technology, in addition to incentives for consumers who purchase clean vehicles.

* Hybrid Trucks And Buses

The Hybrid Vehicle Incentive Program provides funds to replace diesel medium to heavy-duty vehicles, including school buses, with hybrid technology vehicles.

* Clean Cars, Trucks and Vans

The Clean Vehicle Rebate Project offers rebates of up to $2,500 for consumers and agencies and businesses who purchase or lease new eligible alternative fuel vehicles including electric, plug-in hybrid electric and fuel cell vehicles. The ARB's Drive Clean website maintains a database of incentives available.

* Farm and Ranch Conservation

Administered by the Natural Resources Conservation Service, the Environmental Quality Incentive Program (EQIP) was created as a voluntary financial assistance program for farmers and ranchers to help eligible producers install or implement conservation practices on agricultural land.
