EPA Proposes In-Use Testing of Heavy-Duty Diesel Emissions
Release Date: 06/03/2004

(06/03/04) EPA is proposing a manufacturer-run, in-use emissions testing program for heavy-duty diesel trucks. Under this program, engine manufacturers will measure emissions from their diesel engines in highway applications using portable onboard emission measurement systems. A pilot program is proposed to begin in 2005 with the fully enforceable program beginning in 2007 when the new requirements take effect. The proposal stems from a settlement agreement between EPA and the Engine Manufacturers Association that was announced in June of 2003. This cooperative effort between EMA and EPA represents a significant advance in helping to ensure that the benefits of more stringent emission standards are realized under real-world driving conditions.
