About the Clean Heavy-Duty Vehicles Program

The Inflation Reduction Act invests $1 billion to replace existing non-zero-emission heavy-duty vehicles with zero-emission vehicles, support zero-emission vehicle infrastructure, and to train and develop workers.

At least $400 million will be used to fund projects serving communities located in an area in nonattainment with the  National Ambient Air Quality Standards. The EPA is offering funding to eligible recipients to replace existing non-zero-emission Class 6 and 7 heavy-duty vehicles with eligible Class 6 and 7 zero-emission vehicles. To support zero-emission vehicle adoption and deployment, funding may also be used for:

  • zero-emission vehicle refueling infrastructure;
  • workforce development and training; and
  • project implementation costs.

The EPA has announced a new Notice of Funding Opportunity (NOFO) in April 2024, which offered up to $932 million in funding for eligible clean heavy-duty vehicles. The application period closed at 11:59PM (ET) on July 25, 2024. The EPA anticipates notifying selectees by November 2024 and awarding the grants by February 2025.

Application Documents

The 2024 Clean Heavy-Duty Vehicles Grant Programs NOFO included information on how to prepare and submit an application package. All application packages must have been received by 11:59 PM (ET) on Thursday, July 25, 2024. via Grants.gov in order to be considered for EPA funding. 

Application Reference Material

*The intent of the School Board Awareness Certification and Electric Utility Partnership Template listed as supplemental application forms for the CHDV Grant Program is to ensure awareness of all parties involved in the potential new bus project. These documents are not binding, meaning that applicants do not need to complete a full utility analysis or otherwise fully commit to proceeding with the potential new bus project prior to being selected for funding. For the School Board Awareness Certification, an authorized representative may include, for example, the Superintendent or their representative, who could sign the form after notifying an appropriate person at the Board of the application for the potential new bus project. This early communication is meant to provide notice and the EPA fully expects that grant awardees and their appropriate school board will have additional communications as needed as part of the award acceptance process. If applicants are unable to complete the cost estimate, scope of utility upgrades, and/or time estimate on the required Electric Utility Partnership Template by the application deadline, but have been able to complete the rest of the template, including all signatures, a partially completed form can be submitted with the intent to complete the form by award notification, if selected.

If an applicant has not received a response from their local utility(ies) after repeated attempts to discuss the Utility Partnership Template, then they may submit the document with signatures from all parties involved in the application except for the utility, with the understanding that there will be continued outreach with the utility after the application deadline. During application review, the EPA may reach out to request an updated copy of this form that includes all required signatures. The EPA expects all the appropriate signatures to be present at the time of award, and omission of these signatures may compromise an applicant’s selection status. The applicant should also email the CHDV Helpline with the following information: name of the utility, name of utility point of contact they’ve been working with (or attempting to work with), and information on when the applicant attempted to contact the utility about the Partnership Template with no response.

Application Process

Applicants were required to submit applications electronically to the EPA through Grants.gov. The Grants.gov registration process required that your organization have a Unique Entity Identifier (previously known as the DUNS number) and a current registration with the System for Award Management (SAM.gov); the process of obtaining both could take a month or more for new registrants.

Potential applicants without a Grants.gov account are encouraged to initiate the Grants.gov registration process ahead of the release of the Notice of Funding Opportunity since the registration process can take a month or more.

Organizations applying to this funding opportunity must also have an active the System for Award Management registration. If you have never done business with the Federal Government, you will need to register your organization in SAM.gov. If you do not have a SAM.gov account, then you will create an account using the government sign in service 1 (login.gov) to complete your System for Award Management registration. The registration is FREE. The process for entity registrations includes obtaining Unique Entity ID (UEI), a 12-character alphanumeric ID assigned an entity by SAM.gov, and requires assertions, representations and certifications, and other information about your organization. Please review the Entity Registration Checklist for details on this process. It is recommended to begin the System for Award Management registration process prior to applying to this grant competition; registration may take more than a month to complete.

Applicants with existing Grants.gov accounts are encouraged to check the status of your System for Award Management account and address any account issues in advance of applying.

Please note that System for Award Management registrations do expire, and inactive accounts must re-register to be able to submit an application. If you have done business with the Federal Government previously, you can check your entity status using your government issued UEI to determine if your registration is active. The System for Award Management requires you renew your registration every 365 days to keep it active. Applicants must ensure that all registration requirements are met in order to apply for this opportunity through Grants.gov and should ensure that all such requirements have been met well in advance of the application submission deadline.
