Clean Air For All: Moyer/FARMER/CAPP Grants

IMPORTANT NOTICE: The Clean Air For All Programs initial application period is currently closed.

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. Funded by the California Air Resources Board (CARB), the Clean Air For All Program has provided more than $91 million dollars in funding to projects in San Diego, successfully reducing air pollutant emissions that are early and surplus to regulatory requirements.

The Clean Air for All solicitation is for the following three grant programs:

  • Carl Moyer Memorial Air Quality Standards Attainment Program (Moyer)
  • Funding Agricultural Replacement Measures for Emission Reductions (FARMER)
  • 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.

Applications are submitted through the County's Citizen Access online application system
