Diesel Emission Reduction Project Funding

The Iowa Department of Transportation (IowaDOT) provides funding for medium- and heavy-duty on-road new diesel or alternative fuel vehicles or engine repowers and replacements, as well as off-road repowers and replacements. Both government and non-government entities that own and operate diesel fleets and equipment are eligible for funding. Vehicles and equipment that qualify for replacement or repower include:

  • Model Year (MY) 2009 or older Class 4-8 school buses, shuttle buses, and transit buses;
  • MY 1992-2009 Class 4-7 local freight trucks;
  • MY 1992-2009 Class 8 drayage trucks; and
  • Freight switchers, ferries and tugs, marine vessel shorepower, airport ground equipment, and forklifts and port cargo handling equipment.
This grant program is funded by Iowa's portion of the Volkswagen Environmental Mitigation Trust. For more information, including how to apply, see the IowaDOT Volkswagen Clean Air Act Partial Settlements website.
