Starting March 14, 2025, South Coast AQMD will accept applications for funding to replace older, heavy-duty diesel engines and equipment with cleaner alternatives, such as electric, alternative fuel, or cleaner diesel technologies. 

The Carl Moyer Memorial Air Quality Standards Attainment (or Carl Moyer) Program supports cleanerthan- required engines, vehicles, and equipment. The Surplus Off-Road Opt-in for NOx (or SOON) program focuses on reducing emissions beyond the requirements of state regulations. Since 1998 and 2008, these programs have helped improve air quality by encouraging equipment owners to upgrade to cleaner technologies ahead of regulatory deadlines. The Carl Moyer Program can also help support installation of zero-emission infrastructure. 

Who Can Apply?
Any public or private heavy-duty on-road or off-road project that reduces emissions of NOx, PM, or ROG is eligible. Applications must be submitted online by 1:00 PM PST on Tuesday July 1, 2025. 

Funding Details:
Grant amounts de pend on the cost-effectiveness and emissions benefits of the project.
