Clean Air For All: Moyer/FARMER/CAPP Grants

(Updated 1/9/2022)

The San Diego County Air Pollution Control District launched the Clean Air for All Grant Campaign to help businesses, nonprofits, and government agencies swap their polluting heavy machinery and equipment for electric and low carbon emission alternatives.

The application period is closed as Friday, January 7, 2022 at 5 p.m.  

This Clean Air for All solicitation is for three grant programs:

Carl Moyer Memorial Air Quality Standards Attainment Program (Moyer), Funding Agricultural Replacement Measures for Emission Reductions (FARMER), and Community Air Protection Program (CAPP). Grant applicants are not required to familiarize themselves with these funding sources as District staff will match projects with the most appropriate funding program.

Funding is also available for Goods Movement Emission Reduction Program (GMERP)-eligible on-road projects (such as replacing Class 5 through 8 heavy-duty diesel trucks that move goods and infrastructure for truck electrification/hydrogen fueling) and commercial harbor craft replacement, repower, or retrofit projects; the GMERP details and Notice of Funding Availability are found at: GMERP
