On May 13, 2026, we attended the South Coast Air Quality Management District’s (South Coast AQMD) Second Public Webinar on the WAIRE Mitigation Program. Here is what you need to know.

Program Background

South Coast AQMD is currently developing the WAIRE Mitigation Program, which will provide incentive funding for eligible NOx and Diesel Particulate Matter emission reduction projects at warehouses and surrounding communities. The program will be funded through mitigation fees collected by South Coast AQMD under the WAIRE Rule.

Year One: A Simplified Approach

South Coast AQMD staff is currently developing the first year of the WAIRE Mitigation Program and plans to keep the program “as simple as possible in its first year.” To that end, South Coast AQMD anticipates funding only purchased Class 4-8 zero-emission (ZE) vehicles, ZE off-road yard trucks, and electric charging/hydrogen fueling stations during the first year of the program.

One important note: all charging or fueling infrastructure funded under the program, except for infrastructure solely for charging or fueling off-road yard trucks, must be “publicly accessible.” South Coast AQMD is currently evaluating the definition of publicly accessible.

What Is Not Expected to be Funded in Year One

South Coast AQMD does not anticipate offering funding in the first year for:

• Leased ZE or near-ZE vehicles
• Energy storage projects
• Green hydrogen projects
• Electric transport refrigeration unit (eTRU) charging projects

Future Years & Application Timeline

For future years, South Coast AQMD staff is currently evaluating whether they will provide funding for:

• Leased ZE vehicles
• Low NOx trucks
• Class 2b and Class 3 delivery vehicles
• Decommissioning of diesel fueling equipment, if paired with ZE charging infrastructure

South Coast AQMD tentatively plans to open the Grant Management System for application intake in August 2026.

Looking Ahead

We will continue to monitor developments related to the WAIRE Mitigation Program and other air quality programs.
