The Indiana Department of Environmental Management (IDEM) announced the availability of funding for the next round of grants for Indiana’s DieselWise Program.
$750,000 will be available through the U.S. EPA Diesel Emission Reduction Act (DERA) program to clean air projects designed to reduce diesel emissions from onroad and nonroad vehicles and equipment across Indiana.
The program centers around the replacement of diesel-powered vehicles, equipment and engines with cleaner solutions. Vehicles under the program include transit buses, school buses, refuse haulers and construction equipment. Additionally, the program will fund eligible replacement of diesel engines or gensets in marine vessels and locomotives.

Awards will be distributed in amounts ranging from $50,000 to $250,000. The DieselWise Program in Indiana has implemented clean diesel projects on nearly 4,000 vehicles across the state, an investment totally over $25 million.
Public and private entities may submit applications. The request for proposals is due Feb. 28, 2025. Indiana will only accept electronic grant proposals submitted in PDF format along with the DieselWise Indiana Fleet spreadsheet in Excel or another similar format to Shawn M. Seals at SSeals@idem.IN.gov.
