Efforts by EPA to Implement the Heavy-Duty Highway Diesel Program

Since the standards were finalized in 2001, EPA has worked to ensure a smooth transition. EPA has sponsored workshops and technology review panels, and issued progress reports and technical amendments to the standards. In late 2005, EPA began working with the Clean Diesel Fuel Alliance, a group of more than 20 industry, government and consumer organizations. The Alliance will provide information on the benefits of ULSD and cleaner-burning diesel cars, trucks and buses. For more information about the Clean Diesel Fuel Alliance, see http://www.clean-diesel.org.

On this page you will find basic and consumer information about the Highway Diesel Rule (the "2007 Highway Rule") heavy-duty engines, and diesel fuel.
