Diesel Emissions Reduction Act (DERA) authorizes the U.S. Environmental Protection Agency (EPA) to allocate funds to states for the establishment of clean diesel projects that will reduce diesel emissions in areas of concern using cost-effective projects. The amount of funding available for allocation and the project requirements can change from year to year.
The 2015 grant is the seventh DERA allocation for the State of Iowa. The DNR - Air Quality Bureau created a competitive DERA grant program to help fund voluntary diesel exhaust reduction projects in areas where some of the highest ozone and PM2.5 concentrations in the state occur.
The Department received two (2) proposals meeting all qualification requirements, requesting funds totaling $227,500. To reduce mobile diesel engine emissions in as many Iowa locations as possible, the Department negotiated with both parties to make a slight decrease in their requested DERA funding so that both projects could proceed. When completed, the projects have the potential to cumulatively reduce NOx, PM2.5, HC, and CO emissions from diesel exhaust by over 90%. In December 2015, the DNR – Air Quality Bureau awarded DERA funding for the following projects:
Plymouth County: $55,000
Plymouth County will replace two 2002 International tandem trucks with two new 2016 tandem trucks. The Class 8a trucks are used to primarily haul material and plow snow from roads. Recipient will provide a match of funds estimated at $215,000.00.
City of West Des Moines: $125,500
The City of West Des Moines will replace a 1995 E-One fire engine with a new fire engine that will meet current diesel emission standards. The replaced fire engine will be a “first out” vehicle for response to emergencies within the City of West Des Moines and used as needed to assist other area communities in emergency situations. Recipient will provide a match of funds estimated at $541,500.00.
There are two different programs – the State program and the National program. Additional information on the DERA Program is available at
Eligible vehicles for DERA grant funding may include buses, medium or heavy duty trucks, non-road engines, equipment, or vehicles, marine engines, and locomotives. The vehicles must have been manufactured between 1991 and 2006 and meet certain remaining useful life requirements. Retrofit technologies that are verified and certified by EPA or California Air Resource Board (CARB), are eligible for 100 percent reimbursement with DERA grant money.
