Carl Moyer Program

carl moyer program 2

The Carl Moyer Program was established in 1998 as a partnership between the California Air Resources Board (CARB) and local air districts. This grant program provides funding for replacing, repowering, or retrofitting eligible heavy-duty engines with cleaner-than-required technology.

The Funding Agricultural Replacement Measures for Emission Reductions (FARMER) Program provides funding through local air districts for agricultural harvesting equipment, heavy-duty trucks, agricultural pump engines, tractors, and other equipment used in agricultural operations. The FARMER Program is supported in part by California Climate Investments, a statewide program that puts billions of Cap-and-Trade dollars to work.

At this time we are still unsure when applications will be available in 2021 for Carl Moyer and FARMER Program funding. Funding may be pushed back this year due to statewide funding delays.

The application period for Year 22 of the Carl Moyer Program and Year 3 of the FARMER Program closed on July 10, 2020. The forms below are for informational purposes and may change in the future.

Off Road Equipment Program (Ag Tractors, Off-Road Ag Equipment, Class 7 Diesel Forklifts, Off-Road Construction Equipment [must comply with In-Use Off Road Regulation], Large Spark Ignited Equipment [must comply with LSI Regulation], Portable Equipment)
Off Road Equipment Repower and Retrofit (including Portable and Stationary Ag. Engine Repowers, Pump Electrification)
On Road Heavy-Duty Vehicle Program (Ag Trucks, School Buses, Emergency Fire Apparatuses, Heavy Duty Truck Retrofit and Replacement [limited opportunities due to Truck and Bus Regulation])

Please review instructions and application forms carefully and attach all required documents. If you have questions, please call us for assistance. Incomplete applications will be returned and risk being excluded from consideration.

CARB produced a document to assist applicants subject to state regulations (Truck and Bus Rule, In-Use Off-Road Regulation, etc.) with determining eligibility. Applications subject to a state regulation must go through a compliance check prior to funding.

For questions, more information, or to be notified of future funding opportunities, call Jason Mandly at (530) 332-9400, extension 108, or email
