The Environmental Protection Agency announced a plan last April 15 to dramatically reduce non-highway diesel emissions. The proposal would affect construction, agricultural and industrial equipment. Engines used in such equipment were not included in the consent decree signed by makers of on-highway engines, which reduced emissions effective Oct. 1, 2002. The plan for non-highway equipment would begin with new engines in 2008 and would be fully implemented by 2014.
The proposal would reduce soot emissions or particulate matter by more than 90 percent and, for the first time, incorporate advanced emission controls into non-road equipment. Diesel sulfur content would be cut 99 percent, according to an agency statement. For more information, visit this site.
