Funded Projects

Examples of what this program has supported.

FY2025 A total of 58 projects were awarded that are expected to replace over 1,200 school buses and over 700 vocational vehicles (including street sweepers, utility trucks, refuse haulers, bucket trucks, box trucks, transit buses, step vans, fire and rescue vehicles, and other vocational vehicles). Program oversight and compliance has been integral from the start of the program. For example, the EPA has provided trainings for grantees on: 1) compliance with EPA and Federal grant requirements, 2) completing Quality Assurance Projection Plans for compliance with reporting requirements, and 3) completing progress reports to ensure that the EPA can appropriately review project progress . Grantees are working to procure new vehicles, which includes completing the competitive procurement process and signing contracts with vendors or sub-recipients. A subset of grantees are using grant funds to award rebates to local private fleets and are thus working to review and accept applications for their rebate program.

Program Objective

Section 60101 of the Inflation Reduction Act of 2022 (or IRA) amended the Clean Air Act by inserting section 132 (42 U.S.C. 7432) to authorize the EPA to make awards of grants to eligible recipients for up to 100 percent of the costs for replacing an eligible vehicle with a new, cleaner heavy-duty vehicle; purchasing, installing, operating, and maintaining infrastructure needed to charge, fuel, or maintain cleaner vehicles; and other activities related to the deployment of cleaner heavy-duty vehicles. IRA appropriated $1 billion for the program, $400 million of which must be spent on projects to replace eligible vehicles that serve 1 or more communities located in an air quality area designated as nonattainment for any air pollutant. The EPA’s objectives for the Clean Heavy-Duty Vehicles Program are to: (1) reduce air pollution, especially in non-attainment areas; and (2) encourage the sustainable deployment of new, cleaner Class 6-7 vehicles.
