About the Clean Heavy-Duty Vehicles Program

The Inflation Reduction Act of 2022 directs EPA to establish a Clean Heavy-Duty Vehicles (CHDV) 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.

More than $400 million will be used to fund projects that serve one or more communities located in areas designated as being in non-attainment with the National Ambient Air Quality Standards.

Notice of Funding Opportunity - Closed

The 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 nby no later than Thursday, July 25, 2024 at 11:59PM (ET) to be considered for funding. The EPA is no longer accepting applications for CHDV grant funding. Refer to the CHDV Selections page for information on tentative selections made under this grant funding opportunity.

Eligible Activities

Eligible activities and costs for the 2024 Clean Heavy-Duty Vehicles grant program include:

  • The incremental cost of replacing a non-zero-emission Class 6/7 heavy-duty vehicle with an eligible Class 6/7 zero-emission vehicle;
  • The purchase and installation of refueling infrastructure that will support vehicles replaced under this program;
  • Driver/mechanic training related to the maintenance and operation of new technologies, and vehicle warranties; and
  • Costs directly related to the implementation, management, and oversight of the project, including recipient and subrecipient personnel and benefits, contractual services, consulting on vehicle deployments, travel, supplies, and indirect costs.

Eligible Applicants

The following entities are eligible to apply under the 2024 Clean Heavy-Duty Vehicles Grant Program:

  • States, including U.S. territories
  • Municipalities, including public school districts
  • Indian Tribes
  • Nonprofit school transportation associations

Note that while third-party contractors, such as transportation service providers and vehicle and charging equipment manufacturers, were not eligible to apply directly, they may still participate in the CHDV Grant Program by encouraging potential applicants to apply and working with grantees through the bidding process after grants are awarded.

Eligible Vehicles

Eligible vehicles under the 2024 Clean Heavy-Duty Vehicles Grant Program include:

  • Class 6 and Class 7 school buses under a School Bus Sub-Program
  • Class 6 and Class 7 box trucks, cargo trucks, emergency vehicles, refuse/recycling haulers, shuttle buses, step vans, transit buses, utility vehicles, and other vocational vehicles under a Vocational Vehicles Sub-Program.

Eligible Existing Vehicles to be Replaced

To be eligible for replacement, existing vehicles must:

  • Be a Class 6 or Class 7 heavy-duty vehicle with Gross Vehicle Weight Rating between 19,501 lbs to 33,000 lbs.
  • Be fully operational at the time of application submission. An operational vehicle should be able to start, move, and have all necessary parts to be operational.
  • Be an engine model year 2010 or older diesel-powered vehicle that will be scrapped if selected for funding. If a fleet has no eligible EMY 2010 or older diesel-powered vehicles, the fleet can either:
    1. Scrap an EMY 2010 or older non-diesel internal combustion engine (ICE)-powered vehicle;
    2. Scrap, sell, or donate an EMY 2011 or newer diesel or non-diesel ICE-powered vehicle; or
    3. Move an EMY 2011 or newer diesel or non-diesel ICE-powered vehicle to a “reduced service” fleet and scrap an EMY 2010 or older reduced-service vehicle in its place.

Additional requirements for vehicles being replaced through the School Bus Sub-Program include that vehicles must:

  • Be a Class 6 or Class 7 school bus that has provided bus service to a public school district for at least three days/week on average during the 2022/2023 school year at the time of applying, excluding emergency-related school closures.

Additional requirements for vehicles being replaced through the Vocational Vehicles Sub-Program include that vehicles must:

  • Have accumulated at least 7,000 miles/year during each of the two years prior to replacement.
    • The mileage of two vehicles may be combined to reach 7,000 miles/year where two or more vehicles will be replaced by a single vehicle.
    • For Tribal and territory applicants, the mileage minimum is 5,000 miles/year during each of the two years prior to replacement.
    • If a vehicle does not meet the mileage requirement, the applicant can demonstrate that the vehicle has idled at least 500 hours/year during the two years prior to replacement.

Eligible New Replacement Vehicles

To be eligible as a replacement, new vehicles must:

  • Be a zero-emission vehicle
  • Be a Class 6 or Class 7 heavy-duty vehicle
  • Be an engine model year 2023 or newer that is certified to conform with all applicable Federal Motor Vehicle Safety Standards
  • Be ordered only after receiving official notification of award for EPA funding
  • Be purchased, not leased or leased to own
  • Not be manufactured or retrofitted with, or otherwise have installed, a power unit or other technology that creates air pollution within the vehicle
  • Not be purchased or otherwise subsidized with other federal grant funds
  • For this funding opportunity, it has been determined that school buses are not subject to Build America, Buy America provisions. EPA Project Officers can provide additional information to grantees on the applicability of BABA provisions to vocational vehicle projects. Please refer to the Grantee Resources page for additional information.

Eligible Infrastructure

Electric Charging Infrastructure

Eligible electric infrastructure is limited to installations and upgrades behind the electric meter. This can include, but is not limited to, charging equipment (such as alternating current Level 2 charging equipment, direct-current fast charging equipment, or vehicle-to-grid enabled equipment); design and engineering; installation costs such as trenching, wiring, and electrical upgrades, labor, and permitting; and related intelligent equipment and software designed to monitor vehicle and infrastructure performance (such as telematics or charge management software).

  • EPA funds must not be used for any infrastructure costs associated with work on the utility’s side of the electrical meter.
  • All AC Level 2 charging infrastructure purchased under this program must be EPA ENERGY STAR certified at the time of purchase. The EPA strongly recommends that all other charging infrastructure funded under this program be listed by a Nationally Recognized Testing Laboratory. The EPA also strongly encourages recipients to consider long-term fleet electrical needs when installing charging equipment. Installing additional electrical capacity on the customer side of the meter to support future charging needs (e.g., purchasing and running additional electrical conduit during trenching and wiring upgrades) is an allowable use of funds.
  • All electricians installing, operating, or maintaining EVSE are required to be certified from the Electric Vehicle Infrastructure Training Program, or another program approved by the EPA in consultation with the Department of Labor and Department of Transportation. For projects requiring more than one electrician, at least one electrician must meet the requirements above. Recipients should request and maintain proof of EVITP certification from their electricians for purposes of project audits.
  • Applicants should be aware that Build America, Buy America requirements apply to eligible vehicle charging infrastructure equipment.

Fueling Infrastructure

Eligible fueling infrastructure includes fueling infrastructure for new hydrogen fuel cell vehicles, including, but not limited to, storage tanks, liquid and gaseous pumps and vaporizers, compressors, heat exchangers, chillers, piping and pipelines within the relevant facility, and high-pressure dispensers (including hose, nozzles, and meters) needed to fuel the new hydrogen fuel cell electric vehicles funded under the project.

  • Under the CHDV Grant Program, Build America, Buy America domestic sourcing requirements apply to eligible vehicle fueling infrastructure equipment. Please refer to the Grantee Resources page for additional BABA-related information.
