Diesel Emissions Reduction Grants

The New Hampshire Department of Environmental Services (NHDES) provides U.S. Environmental Protection Agency Diesel Emissions Reduction Act (DERA) funding for projects that reduce diesel emissions in New Hampshire. Funding for up to 100% of eligible project costs is available for businesses, schools and school districts, municipalities, marine operators, public and private transit companies, and local or state agencies that reduce diesel emissions by converting engines to alternative fuels, retrofitting exhaust controls, purchasing new vehicles, or adding idle reduction equipment. Eligible alternative fuels include propane, compressed natural gas, and electricity. Grants will be awarded on a competitive basis, with equity and environmental justice considerations as part of the evaluation criteria. For more information, including funding amounts and how to apply, see the NHDES New Hampshire DERA Project website.

Idle Reduction Weight Exemption

Any heavy-duty vehicle equipped with an auxiliary power unit or other qualified idle reduction technology may exceed the state gross, axle, tandem, or bridge formula weight limits by up to 550 pounds. To qualify for this exemption, drivers must be able to provide proof of the idle reduction technology’s weight through written certification. Drivers must also be able to prove through demonstration or certification that the idle reduction technology is fully functional at all times.
