Carl Moyer Program

May contain: vehicle, transportation, truck, bus, bulldozer, and tractor

Program Objectives 
To improve the quality of the air in the Antelope Valley by funding local, cost-effective projects to upgrade heavy-duty equipment (GVWR greater than 14,000 lbs.) using proven technologies and procedures that reduce oxides of nitrogen (NOx), particulate matter (PM) and reactive organic gases (ROG).  Diesel exhaust is a serious public health risk, considered the number one airborne carcinogen in California, responsible for 70 percent of the cancer risk in CA from toxic air contaminants, and a major contributor to lung and heart problems. Funding is provided by California Air Resources Board’s (ARB) Carl Moyer Memorial Air Quality Standards Attainment Program and DMV Surcharge Fees. Approximately $1 billion dollars has been awarded to date to eligible projects in the past 20 years reducing emissions by approximately 8,500 tons.

Eligible projects include:  Replacement, Repower, Retrofit (Highest Level PM and NOx reductions), TRU Retrofit and Idling Reduction Retrofit.  NOTE**On-road projects are limited due to regulation and/or having 10 or fewer vehicles, GVWR less than 26,000lbs.  In addition ALL projects must operate a minimum of 75% in California and 50% within the District.  Agriculture Off-Road projects are unlimited.  Off-Road Construction equipment for Large Fleets are limited**

It is recommended to call the AVAQMD grants coordinator to discuss project eligibility and estimate of grant benefit before submitting an application.  Non-compliant equipment/fleet is ineligible.

Off-Road Agricultural Equipment Replacement, Repower or Retrofit for 25hp or more

  • Uncontrolled, Tier 1 or Tier 2 fully functional, self-propelled off-road equipment to be scrapped and replaced with newer current emission standard engine.

Off-Road Compression Ignited Equipment Replacement, Repower or Retrofit for 25 hp or more

  • Off-Road Equipment: Construction, mining, rental, airport ground support and other industries
  • Small Fleets 2,500 hp or less (Limited Funding Opportunity thru Dec. 31, 2025)
  • Med. Fleets 2,501 to 5,000 hp (Limited to Replacement with Zero Emissions)
  • Lrg. Fleets > 5,000 hp (Limited to Replacement with Zero Emissions)
  • Off-Road Large-Spark Ignition Equipment (Limited to Replacement with Zero Emissions or other Alternative Fuel).

Portable and Stationary Equipment (Repower and/or Retrofit)

  • Tier 1 and Tier 2 - Limited opportunity

Emergency Vehicles (Fire Apparatus) Replacement

  • Eligible projects include, but are not limited to pumpers, ladder trucks, and water tenders in which a new or used replacement vehicle with an engine meeting the current model year California emission standard replaces an older, more polluting fire apparatus. The older, replaced vehicle must be destroyed. A fire truck reuse option is also available on a case-by-case basis. The fire truck reuse option allows fire departments to give away the existing old vehicle and destroy another older vehicle in its place
  • GVWR > 14,000 lbs.
  • Auxiliary Engines are ineligible
  • Up to 80% in grant funding (less may actually be awarded depending on the results of the cost-effectiveness evaluation).

Funding Availability 
For 2024 there is a projected $2m  in Carl Moyer Program funds available for eligible projects.  Project applications are accepted on an open basis.  Projects are selected based on competitive review of emission reductions, cost-effectiveness, viability, surplus to regulation, and operations within the AVAQMD for the purpose of local emission reductions.

Project Selection 
To be eligible for funding proposed projects must meet the requirements of the most recently approved ARB Carl Moyer Memorial Air Quality Standards Attainment Program guidelines and advisories.
