Engine Exhaust Retrofit

Engine Retrofit


Status: Application Period is currently OPEN for the Carl Moyer Program.



The Carl Moyer Grant Program was established in 1998 to fund the incremental cost of cleaner-than-required heavy-duty engines. Currently, there is $10 Million available for funding Carl Moyer Program projects operating in the Sacramento Federal Ozone Nonattainment Area (SFNA), specifically in Sacramento County, Placer County, Yolo County and some parts of Solano County and southern Sutter County. The existing equipment must be self-propelled and the existing engine must be greater than or equal to 25 horsepower. The new or replacement engine must have a similar horsepower rating as the existing engine, with a maximum increase of 25% as determined by staff.

Exhaust System Retrofits. The Off-Road Engine Retrofit Program provides funds to retrofit off-road diesel engines with the highest level Verified Diesel Emission Strategy (VDECS). VDECS reduces harmful engine exhaust emissions resulting from an engine's post combustion process.
