The Carl Moyer Memorial Air Quality Standards Attainment Program provides incentive grants for cleaner-than-required engines, equipment, and other sources of pollution providing early or extra emission reductions. Eligible projects include cleaner on-road, off-road, marine, locomotive, and stationary agricultural pump engines. The program provides monetary grants to private companies and public agencies to clean up their heavy-duty engines beyond that required by law through retrofitting, re-powering, or replacing their engines with newer and cleaner engines.
The Tuolumne County Air District receives $200,000 annually for local engine retrofit and replacement projects. Each year, the district accepts applications year-round for funding on a first-come, first-served basis.
