# Notice of Lodging of Proposed Consent Decree Under the Clean Air Act
On October 6, 2016, the Department of Justice lodged a proposed Consent Decree with the United States District Court for the District of Columbia in the lawsuit entitled *United States* v. *Detroit Diesel Corporation,* Civil Action No. 1:16-cv-01982.
The government's complaint alleges that Detroit Diesel violated the Clean Air Act by introducing into commerce 7,786 heavy-duty diesel engines for use in trucks and buses in model year 2010 without a valid EPA-issued certificate of conformity demonstrating conformance with Clean Air Act standards to control nitrogen oxide (NO <sub>X</sub> ) emissions. The complaint also alleges that the engines did not conform to emission standards applicable to model year 2010 engines.
The Consent Decree requires Detroit Diesel to spend $14.5 million on mitigation projects to reduce NO <sub>X</sub> emissions and other pollutants, including replacing high-polluting diesel school buses and locomotive engines with models that meet current emissions standards. Detroit Diesel will also pay a civil penalty of $14 million.
