South Coast AQMD began accepting applications in January 2023 for the Carl Moyer Memorial Air Quality Standards Attainment (Carl Moyer) Program and the Surplus Off-Road Opt-in for NOx (SOON) Program.

The Carl Moyer and SOON Programs focus on cleaning the air by providing incentive funding for the replacement of older heavy-duty diesel equipment with electric, alternative-fuel, or cleaner diesel technologies. Any heavy-duty on-road or off-road project including infrastructure, public or private, which results in NOx, PM, or ROG emission reduction is eligible to apply.

Approximately $51 million is available to support projects within South Coast AQMD’s jurisdiction. Applications are due on May 9th. For more information, full descriptions of eligibility requirements and to apply on-line, please visit our Carl Moyer webpage.
