Clean Diesel Fuel Alliance

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 www.clean-diesel.org.

Highway Diesel Progress Review Reports

Highway Diesel Progress Review Report 2
EPA met with more than 20 companies over the last year and a half to compile an extensive review of the progress by industry to develop clean diesel technologies for the heavy-duty 2007 diesel emissions regulations. The report documents work from a wide variety of government and industry sources to reach its conclusions regarding 2007 readiness.

EPA's review of industry progress shows that engine manufacturers are on target to introduce new engines in 2007; diesel particulate filters that reduce harmful PM emissions by more than 90% will be used by all manufacturers; NOx control will be accomplished using proven technologies, some of which are in production today; and engine manufacturers will conduct early prototype testing with trucking customers in 2005. In 2007, these new clean engines operating on the 15 ppm sulfur diesel fuel will reduce NOx emissions by 50%, reduce PM emissions by more than 90%, will substantially contribute to air quality improvement, help states meet Clean Air Act goals and further protect public health and the environment.

Highway Diesel Progress Review Report 1
The Agency has completed a comprehensive technical review of progress by 1) the manufacturers of diesel engines and emission control systems in developing technology to reduce engine exhaust pollutants, and 2) the petroleum refining industry in developing and demonstrating technologies to effectively lower the sulfur level of diesel fuel. From this review we can conclude that industry progress towards complying with the requirements of the 2007 Highway Diesel program is proceeding at a rapid rate and considering the timeframe of this report (June of 2002) and the remaining lead-time for 2007 and 2010, EPA is confident the program is on track for a successful implementation.

Summary and Analysis of the Diesel Fuel Pre-compliance Reports

Summary and Analysis of the 2008 Nonroad Diesel Fuel Pre-compliance Reports (published Sept. 16, 2008)
Refiners and importers that are planning to produce or import 15 ppm nonroad, locomotive, and marine (NRLM) diesel fuel after 2010 are required to submit annual pre-compliance reports to EPA. This document provides a summary and analysis of the reports that were received in June 2008, including some comparisons to the NRLM pre-compliance reports received in June 2007. The pre-compliance reports generally showed that:

Refiners are implementing plans to desulfurize nonroad diesel (NR) fuel by 2010 and locomotive and marine diesel (LM) fuel in 2012;
Total diesel fuel production is projected to increase from 2010 through 2014;
Refiners are utilizing the flexibilities offered by the regulations;
Total diesel fuel production in each PADD is projected to remain constant or increase; and,
Compared to the 2007 nonroad pre-compliance reports, production and importation of total highway + NRLM diesel fuel beginning June 1, 2010 decreased slightly.

Summary and Analysis of the 2007 Nonroad Diesel Fuel Pre-compliance Reports (published Jan. 17, 2008)
Refiners and importers that are planning to produce or import 15 ppm nonroad, locomotive, and marine (NRLM) diesel fuel after 2010 are required to submit annual pre-compliance reports to EPA. This document provides a summary and analysis of the reports that were received in June 2007, including some comparisons to the NRLM pre-compliance reports received in June 2006. The pre-compliance reports generally showed that:

Refiners are implementing plans to produce 15 ppm nonroad diesel (NR) fuel by 2010 and 15 ppm locomotive and marine diesel (LM) fuel by 2012;
Total diesel fuel production is projected to increase from 2010 through 2014;
Refiners are utilizing the flexibilities offered by the regulations;
Total diesel fuel production in each PADD is projected to remain constant or increase; and,
Beginning June 1, 2010, production and importation of total highway + NRLM diesel fuel are projected to increase compared to the 2006 nonroad pre-compliance reports.

Summary and Analysis of the 2006 Nonroad Diesel Fuel Pre-compliance Reports
Refiners and importers that are planning to produce or import 15 ppm nonroad, locomotive, and marine (NRLM) diesel fuel after 2010 are required to submit pre-compliance reports to EPA. This document provides a summary and analysis of the reports that were received in June 2006, including some comparisons to the NRLM pre-compliance reports received in June 2005. The pre-compliance reports generally showed that:

Refiners are putting in place plans to desulfurize nonroad diesel (NR) fuel in 2010 and locomotive and marine diesel (LM) fuel in 2010;
Refiners have projected an increase in diesel production from 2010 through 2014;
Refiners are utilizing the flexibilities offered by the regulations;,/li>
Diesel fuel volume in all PADDs are projected to remain constant or increase; and,
Refiners project an increase in expected production and importation of total highway + NRLM diesel fuel beginning June 1, 2010, compared to the 2005 nonroad pre-compliance reports.

Summary and Analysis of the 2005 Highway and Nonroad Diesel Fuel Pre-compliance Reports
Any refiner or importer planning to produce or import highway diesel fuel in 2006-2010, and/or 15 ppm nonroad, locomotive, and marine (NRLM) diesel fuel after 2010, is required to submit pre-compliance reports to EPA. The Summary and Analysis and presentation provide a summary and analysis of the reports that were received in June 2005, including some comparisons to the highway diesel reports received in June 2003 and 2004. This preliminary information (for highway diesel fuel) generally follows the trends that were found in the reports from the two previous years. The presentation was given by Chris McKenna of EPA at the 2005 ULSD Workshop (Phoenix, AZ, November 9-11, 2005).

Summary and Analysis of the Highway Diesel Fuel 2004 Pre-compliance Reports
Any refiner or importer planning to produce or import highway diesel fuel in 2006-2010 is required to submit to EPA pre-compliance reports. This document provides a summary and analysis of the reports that we received in June 2004, including comparisons to the reports received in June 2003. This preliminary information generally follows the trends that were found in the 2003 reports, namely that: 1) the industry is on target for complying with the 15 ppm sulfur standard on time; 2) highway diesel fuel production will be sufficient to meet demand; and 3) 15 ppm sulfur diesel fuel will be widely available nationwide.
