The Carl Moyer Program was established in 1998 as a partnership between the California Air Resources Board (ARB) and local air districts. The grant program was designed to fund the incremental cost of cleaner-then-required heavy-duty engines. Originally, the program targeted the reduction of oxides of nitrogen (NOx) emissions, but now includes the reduction of Particulate Matter (PM) and Reactive Organic Gases (ROG). Legislative modification in 2004 expanded the program to include projects that reduce emissions from agricultural sources, light-duty vehicles, and on-road fleet modernization.

The Carl Moyer program provides incentives to purchasers of diesel low-emission on- and off-road medium and heavy-duty trucks, buses, agricultural pumps, for repowering, rebuilding or retrofitting used diesel equipment with cleaner engines.

The 2011 Carl Moyer Guidelines can be reviewed at CARB's website.

The District administers the Carl Moyer Program through a Policies and Procedures Manual approved by the Governing Board annually. The Policies and Procedures Manual for Year 15 (2013) Carl Moyer Program was approved on February 28, 2013.
