Diesel Emissions Reduction Grant Program

The Ohio Environmental Protection Agency administers a Diesel Emissions Reduction Grant Program for the purpose of reducing emissions from diesel engines in trucks, school and transit buses, marine fleets, and locomotives, as well as highway construction equipment. Eligible entities may use this funding for:

  • Projects related to certified engine configurations, including new, rebuilt, or remanufactured engine configurations the U.S. Environmental Protection Agency or the California Air Resources Board has certified;
  • The purchase or use of hybrid electric and alternative fuel vehicles that are allowed under U.S. Federal Highway Administration Congestion Mitigation and Air Quality (CMAQ) Improvement program guidance; or
  • Installation of verified technology including pollution control devices, retrofits, and development of truck stop electrification and auxiliary power units.
To be eligible for funding, fleets must operate at least 65% of the time in Ohio counties that have been designated nonattainment or maintenance for particulate matter (PM) 2.5 and/or ozone. Private fleets are eligible, but they must establish a public-private partnership with a government organization that is eligible for CMAQ funds in order to apply for funding. A minimum 20% non-state and non-federal funding match is required. For more information, including application periods, see the Diesel Emissions Reduction Grant Program website.
