Carl Moyer Program (Heavy-Duty Engines)

NEW!  SCAQMD is no longer accepting applications for the Carl Moyer Program (CMP). 

Please check this website in early 2018 for updated information regarding new Carl Moyer funding opportunities.

The purpose of the CMP is to obtain emission reductions of Nitrogen Oxides (NOx), Particulate Matter (PM10) and Reactive Organic Gases (ROG) from heavy-duty vehicles and other equipment operating in California as early and as cost-effectively as possible. The CMP provides financial incentives to assist in the purchase of cleaner-than-required engine and equipment technologies to achieve emission reductions that are real, surplus, quantifiable and enforceable. 

CMP funding is provided via two legislative bills, SB 1107 and AB 923.  SB 1107 provides approximately $61 million per year in statewide funding, and AB 923 permits air districts in designated non-attainment areas to collect an additional two dollars in vehicle registration fees to expend on programs to reduce emissions from vehicular sources and off-road equipment. A resolution approving such fees was adopted by the SCAQMD Board on December 3, 2004. 

The Carl Moyer Program fills a critical niche in California’s strategy to achieve clean air.  In the past 18 years, the CMP has provided $410 million in funding which has resulted in approximately 6,937 tons per year of NOx and 181 tons per year of PM emission reductions throughout SCAQMD.

What's New:
The California Air Resources Board (CARB) approved new CMP Guidelines on April 27, 2017.  Some of the key changes to the CMP include establishing new cost-effectiveness limits based on consideration of technology and regulatory costs. Other changes include incorporating other public funding sources to leverage CMP funds. For future program announcements, SCAQMD will use the updated guidelines for project evaluations.

Funding Categories:
Below are the specific project categories identified for funding under the SCAQMD 2017 CMP solicitation:  

  • On-Road Heavy-Duty Vehicles, including Emergency Vehicles (Fire Apparatus)
  • Off-Road Equipment, including:
    • Marine Engine Repower
    • Shore Power (Note: Projects within port locations must be surplus to CARB’s At-Berth Regulation and approved on a case-by-case basis.)
    • Construction Equipment (Note: Current CMP Guidelines limit funding opportunities to small and medium fleets, however the SCAQMD encourages large fleets to apply under this PA since the 2017 CMP Guidelines update may include funding opportunities for large fleets.)
    • Agricultural Mobile Equipment (loaders, tractors, water pulls, etc.)
    • Locomotives
    • Cargo Handling Equipment (zero-emission projects only)
