Carl Moyer Program (Heavy-Duty Engines)

NEW!  SCAQMD is no longer accepting applications for the Carl Moyer Program under
Program Announcement (PA) #2018-06 (PDF, 4.8MB).

We encourage you to visit this site in early 2019 for further funding updates for the Carl Moyer Program.

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 19 years, the CMP has provided $467 million in funding which has resulted in approximately 7,598 tons per year of NOx and over 222 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.

In September 2017, the Governor approved AB 134 as an amendment to the Budget Act of 2017.  Under Section 3 of this bill, $250 million will be distributed by CARB to air districts for implementation of projects pursuant to the Carl Moyer Program.  SCAQMD’s allocation of these funds is $107.5 million.  Based on a successful solicitation last year, the SCAQMD’s Governing Board approved about $51 million in eligible projects for AB 134.  This leaves a balance of approximately $50 million in AB 134 funds.  The SCAQMD anticipates the availability of AB 134 funds for eligible projects under this solicitation.  

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.
