Carl Moyer Program (Heavy-Duty Engines)

NEW! South Coast AQMD is No Longer Accepting Applications for the
Carl Moyer Program (CMP).

Please Visit Us Again in Early 2020 for Information on Future Carl Moyer Program 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 South Coast AQMD Board on December 3, 2004. 

The Carl Moyer Program fills a critical niche in California’s strategy to achieve clean air.  In the past 20 years, the CMP has provided $390 million in funding which has resulted in approximately 7,954 tons per year of NOx and over 232 tons per year of PM emission reductions throughout South Coast AQMD.

What's New
In June 2018, the California Governor approved SB 856 that allocates funds in support of the AB 617-Community Air Protection Program.  Under this bill, $245 million are allocated for financial incentives to reduce stationary and mobile source emissions.  The project types listed in the bill include: mobile sources (including projects eligible under the CMP) with zero emission priority, charging infrastructure, especially for medium and heavy-duty vehicles, stationary sources and other projects included in the AB 617 community emission reduction plans.  The South Coast AQMD anticipates the availability of SB 856 funds for this year’s CMP.

The South Coast AQMD also anticipates receiving additional funds from the Funding Agricultural Replacement Measures for Emission Reductions (FARMER) Program for eligible projects under this solicitation. 

AB 1274 (O’Donnell) was signed by the Governor in October 2017 and resulted in the postponement of smog checks on new vehicles from Years 6 to 8, starting on January 1, 2019.  A fee of $25 per year the vehicle is exempted from smog check will be charged by DMV, and the revenues from the fee will be directed to the CMP.  As a result of AB 1274, the funding for this year’s CMP to be administered by the South Coast AQMD was increased by about $4.3 million. 

Each project will be evaluated in accordance with the latest version of the Funding Guidelines for Agencies that Administer California Climate Investments established by the California Air Resources Board, including the CalEnviroScreen tool, to identify those projects that are located within a disadvantaged and/or low-income community.  To see if a particular community is within a disadvantaged or low income community, please visit: to external website.
