The final ruling, which mandates cleaner diesel fuel and an additional 90% reduction in nitrogen oxide (NOx) and particulate matter (PM) emissions beginning in 2007 represents a milestone for EPA. Mandel emphasized that the nationwide availability and use of ultra low sulfur diesel fuel is a prerequisite to engine makers ability to introduce the advanced aftertreatment devices needed to achieve EPA's emission goals. Engine manufacturers will use new aftertreatment technologies to achieve both NOx and PM reductions.
EMA, however, expressed concern that the final rule may not provide the flexibility needed to assure a technologically feasible and cost effective program.
