ACKGROUND

Established pursuant to the Energy Policy Act of 2005, the Diesel

Emissions Reduction Act (DERA) is a voluntary program that

incentivizes vehicle, engine and equipment owners to retrofit exist-

ing heavy-duty diesel vehicles, engines and equipment with new

technology, or replace vehicles, engines and equipment through the

disbursal of federal and state grants and rebates. The DERA pro-

gram generally targets older, dirtier, diesel engines that lack mod-

ern emissions control systems to be upgraded with new tech-

nologies, such as vehicle and/or engine replacements with new die-

sel, alternative fuel, and zero emissions engines or idle reduction

technologies. Funding opportunities for diesel emissions reduction

projects are provided through an annual appropriation by Congress

to the DERA program. The U.S. Environmental Protection Agency

(EPA) administers the DERA program within the Office of Trans-

portation and Air Quality. EPA awarded the first DERA grants in

2008 and continues to award DERA grants and rebates each fiscal

year.
