EPA stands firm on Oct. 2002 deadline
WASHINGTON, D.C. (June 11, 2001) — Rejecting arguments from diesel engine manufacturers, the U.S. Environmental Protection Agency and the Dept. of Justice said they will not delay an October 2002 deadline to meet more stringent emission standards.
The companies wanted more time for testing.
The deadline arose from consent decrees signed by heavy-duty engine manufacturers in 1998. They agreed to produce engines meeting the 2.5 g/bhp-hr standard for oxides of nitrogen (NOx) and nonmethane hydrocarbons by October 2002.
Cummins, Mack, Detroit Diesel, and Volvo have stated that they will meet the deadline using cooled exhaust gas recirculation technology, or EGR. Caterpillar has said it is using an alternative method for reducing emissions that will be ready by the fourth quarter 2003.
