On-Road Truck Grants

Carl Moyer / AB617 / FARMER

Information updated May 31, 2018.

The APCD’s Carl Moyer Incentive Program provides funding to help pay for projects that reduce heavy-duty diesel engine emissions prior to any regulatory requirement. Applicants may qualify for grants totaling up to $500,000, subject to cost effectiveness limits and other requirements of the program. 

Eligible project categories include:

  • On-Road Fleet Modernization Program (Fleet Mod)
  • Infrastructure for Alternative Fueling Stations, Electric Vehicle Charging: Installation of infrastructure for alternative fueling stations, and electric vehicle charging stations.

Fleet Modernization Eligibility

Eligibility for the APCD On-road Fleet Modernization program is limited.  For vehicles subject to the statewide Truck & Bus Regulation, the following eligibility requirements apply:

  • The fleet must be in compliance with the Truck & Bus Regulation.
  • If the baseline (old) truck is over 26,000 lbs. GVWR, it must be equipped with a diesel particulate filter (original equipment or aftermarket).
  • If the baseline truck is 26,000 lbs. GVWR or under, it must have an engine model year of 2004 or newer.
  • The baseline truck must have a final compliance date of January 1, 2021 or later.  The closer the compliance date is, the smaller the potential award amount will be.
  • Documentation of annual mileage is required with the application.  The lower the annual mileage, the smaller the potential award amount.
  • Trucks operating under the low-use exemption are not eligible.
  • In fleets with more than ten vehicles, the replacement vehicle must be an optional low-NOx or zero-emission technology (e.g. electric, CNG, propane), unless the baseline vehicle falls within specified vocations or locations (i.e., school buses, log trucks, low mileage work trucks, agricultural vehicles, and NOx Exempt Area vehicles).

Fleet Modernization Potential Awards

The following tables give some examples of potential grant award amounts, assuming a replacement truck meeting the current diesel engine standards (0.20 g/bhp-hr NOx).  Optional low-NOx or zero-emission projects may qualify for additional funding:

If you would like an estimate of an approximate potential award amount for your on-road project, please email the following information to

  • Old truck Gross Vehicle Weight Rating
  • Model year of the baseline (old) engine
  • Fuel type of the replacement engine (diesel, CNG, electric, etc.)
  • Annual mileage for the last two 12-month periods (from today’s date back approximately 12 months, and from that date back another 12 months)

Community Air Protection Program (AB617)

On May 23, 2018, the APCD Board authorized additional grant funding in the amount of $614.063 from California Assembly Bill 617 - Community Air Grants Program. AB 617 seeks to ensure that all Californians benefit equitably from our State's air quality and climate efforts, especially those who live in the areas of California most severely impacted by air pollution. 

Eligible projects for this funding, which will focus on under-served areas in our county, will be administered using the Carl Moyer grant program guidelines and include, but are not limited to the replacement of diesel equipment, including heavy-duty on-road vehicles (transit, waste haulers, and heavy-duty trucks), agricultural tractors and irrigation engines, and construction equipment.

Also on May 23, 2018, the APCD Board authorized $793,450 of additional grant funding for the Funding Agricultural Replacement Measures for Emission Reductions (FARMER) Program, which provides for the expenditure of funds from Assembly Bill (AB) 134 and AB 109.  These bills provide funding for agricultural harvesting equipment, heavy-duty trucks, replacement or electrification of irrigation engines, tractors, and other equipment used in agricultural operations.  These projects also must be consistent with the Carl Moyer Program guidelines.
