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 25% 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.

  • Agriculture and Construction Equipment
  • Uncontrolled, Tier 1 or Tier 2 fully functional, self-propelled off-road equipment to be scrapped and replaced with newer current emission standard engine.
  • Small Fleets: Limited opportunities
  • Large/Medium Fleets: Very Limited opportunities

Off-Road Compression Ignited Equipment Repower or Retrofit

  • Off-Road Equipment: Construction, mining, rental, airport ground support and other industries
  • Small Fleets 2,500 hp or less thru Dec. 31, 2025
  • Med. Fleets 2,501 to 5,000 hp thru Dec. 31, 2019
  • Lrg. Fleets > 5,000 hp (Limited to Replacement Only with Tier 4)
  • Off-Road Large-Spark Ignition Equipment Retrofit or New Electric
  • Limited Projects: Forklifts, Sweeper/Scrubbers, Industrial Tow Tractors, Airport Ground Support Equipment
  • Small Fleets: 1st Off-Road Regulation compliance date is January 1, 2019.  The final compliance date is January 1, 2028.  Funding opportunities through December 31, 2025.
  • Medium Fleets: 1st Off-Road Regulation compliance date January 1, 2017.  The final compliance date is Janaury 1, 2023.  Funding opportunities through December 31, 2019.
  • Large Fleets: Final compliance date January 1, 2013.  After January 1, 2017 Large Fleets may receive one additional or first opportunity for funding.
  • All other Projects: Aerial lifts, construction, mining, other industrial (Unlimited)

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 2018 there is a projected $725,540 in Carl Moyer Program funds available for eligible projects.  Project applications are accepted on a continual 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.
