Review of Trash fuel by 97 percentt0. The EPA rule was the most significant mobile Collection source initiative since the 1970 Clean Air Act Amendments establishing the U.S. Mobile Source Emission Control Program. Impacts Beginning with the 2007 model year, 100 percent of the on -road diesel heavy duty engines (HDEs) are required to use a diesel particulate filter and 50 percent of the engines are required to use nitrogen oxide (NOx) exhaust control technology. Beginning with the 2010 model year, 100 percent of the on -road heavy -duty diesel engines will require NOx exhaust technology. Figure 2 below provides an illustration of the improvements in engine emissions that have occurred over the last 25 years. With the 2010 standards the emissions from model year 2010 HDE's will be a small fraction of what they were less than 10 years ago.

There are no requirements that fleet operators, including trash haulers, comply with the standards within any specific time period. Relying 10 As of 2006, refiners and importers nationwide are required to ensure that at least 80% of the volume of the highway diesel fuel they produce or import is ultra low sulfur diesel (ULSD) compliant. By 2009 95% of diesel fuel will have a sulfur limit of 15 parts per million (ppm). By December 1, 2010 100% of the diesel fuel sold will need to meet that limit. ULSD fuel enables the use of cleaner technology diesel engines and vehicles with advanced emission control devices, resulting in significant improved air quality. Section 2 - 8
