    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 protoype 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.

    Summary and Analysis of the Highway Diesel Fuel 2003 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 2003. In general, this preliminary information indicates 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.

    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.
