AMES, Iowa – July 2, 2021 – The Iowa Department of Transportation is now accepting grant applications for the U.S. Environmental Protection Agency’s Fiscal Year 2021 Diesel Emission Reduction Act Program (DERA) for diesel fleets in the state of Iowa.  

As part of the Energy Policy Act of 2005, DERA is designed to achieve significant reductions in diesel emissions among on-road and non-road vehicles and equipment, including school buses, medium- and heavy-duty transit buses and trucks, marine engines, locomotives, and other nonroad vehicles, engines, and equipment.

Iowa school districts, transit systems, company fleet managers or other interested parties should go to the DERA grant website to read the program information guide and find out more about the grant process and previous DERA awards.

Applications are being accepted through Sept. 10, 2021.  

The total amount of available DERA funds in Iowa is $857,288, which includes a base grant amount of $342,915 and an Environmental Protection Agency matching incentive bonus of $171,458. In addition, the state is matching that base grant amount with monies from Iowa’s Volkswagen Environmental Mitigation Trust Fund settlement.
