About the Clean Heavy-Duty Vehicles Program
The Inflation Reduction Act of 2022 directed EPA to establish a Clean Heavy-Duty Vehicles grant program to incentivize and accelerate the replacement of existing internal combustion engine heavy-duty vehicles with zero-emission vehicles. To support zero-emission vehicle adoption and deployment, CHDV grant program funding may also be used for:
- zero-emission vehicle refueling infrastructure;
- workforce development and training; and
- project implementation costs.
The Inflation Reduction Act made available $400 million for EPA to award grants for projects that serve one or more communities located in designated nonattainment areas where air pollution levels persistently exceed the National Ambient Air Quality Standards.
Notice of Funding Opportunity - Closed
EPA announced a Notice of Funding Opportunity in April 2024, which offered grant funding for eligible zero-emission school buses and vocational vehicles, infrastructure, and associated workforce training and development.
All electronic application packages were due through Grants.gov no later than Thursday, July 25, 2024 at 11:59PM (ET) to be considered for funding. EPA is no longer accepting applications for CHDV grant funding. Refer to the CHDV Grant Program Awards page for information on awards made under this grant funding opportunity.
