EPA notes industry progress on 2007 emission regs

| 6/26/2002

In a June "Highway Diesel Progress Review," the Environmental Protection Agency (EPA) reports there's progress being made by diesel engine manufacturers, emission control makers, and the petroleum refining industry toward meeting tough regulations of the 2007 Highway Diesel program.

The EPA regulations call for a reduction in particulate matter and oxides of nitrogen that are 90 percent and 95 percent below current standards. The standards are based on use of high-efficiency catalytic exhaust emission control and other devices. In addition, refiners are developing technologies to reduce the sulfur level of diesel fuel.

As part of the review, EPA met with engineers from more than 20 companies affected by the 2007 regulations. "Every major engine manufacturer that we visited told us that they expect to have emission-compliant products in 2007," the review noted. "Moreover, some refining companies are ahead of schedule and will be capable of producing significant volumes of 15 ppm sulfur diesel fuel as early as next year."

EPA said International Truck and Engine Company has already certified an engine with a catalyzed diesel particulate filter that meets the 2001 standards for use in fleets where 15 ppm diesel fuel is already available.
