New Hampshire Clean Diesel Grant Program
DERA grant program aims to reduce emissions from diesel engines
The New Hampshire Clean Diesel Grant Program is funded by EPA through the Diesel Emissions Reduction Act (DERA) with additional funding from the New Hampshire VW Mitigation Trust. The program is managed by the Air Resources Division, Technical Services Bureau of NHDES. The goal of this grant program is to reduce the emissions from diesel engines in the State. Projects eligible for funding include vehicle and equipment replacement, engine replacement, idle reduction technologies, and aerodynamic technologies. Funding opportunities are guided each year by the annual DERA work plan. See the 2022 NHDES Work Plan.
Grant funding reimburses a portion of eligible project costs; the portion depends on the project type. For example, a project replacing a diesel vehicle with an electric vehicle can be reimbursed for up to 45% of the project cost; a project replacing an old diesel vehicle with a newer, cleaner diesel vehicle can be reimbursed for up to 25% of the project cost.
This program is a reimbursement program only.
The NH Clean Diesel Grant Program has received additional DERA funding!
As of February 2024, NHDES has been awarded new DERA funding. We anticipate releasing a competitive Request for Proposals (RFP) by April 2024! This will be structured and have similar requirements to the prior RFP. Please reference the documents below for guidance and contact Mobile Sources with specific project questions.
Request for Proposals for Round 4 CLOSED as of September 15, 2023. Thank you for your proposals.
NHDES requested proposals for eligible diesel emission reduction projects utilizing EPA DERA federal fiscal year 2022 funds between May 25 and September 15, 2023.
After the fourth round of the Request for Proposals, NHDES has received 18 proposals, total. Eligible proposals were evaluated by the Scoring Committee. As of November 2023, three (3) selected proposals are currently in the contracting phase and are pending approval by NH Governor & Executive Council (G&C). Neither eligibility nor selection guarantee funding. Projects must be approved by G&C before funds may be expended.
Timelines, funding amounts, scoring criteria, eligibility restrictions, and more can be found in the Request for Proposals and the EPA Program Guide, which is available through the links below.
