Rival Engine Manufacturers Challenge Conformity Certificates Issued to Navistar

摘要

The Environmental Protection Agency disregarded a prior federal appellate court decision when it refused to revoke certificates of conformity that allowed Navistar Inc. to exceed nitrogen oxides emissions standards for its engines, other engine manufacturers argued Sept. 11 (Daimler Trucks N. Am. LLC v. EPA, D.C. Cir., No. 12-1179, oral arguments 9/11/13). The EPA should have revoked Navistar's certificates of conformity after the U.S. Court of Appeals for the District of Columbia Circuit vacated an interim final rule that would have allowed the company to pay penalties for producing heavy-duty diesel engines through 2012 that do not meet the nitrogen oxides emissions standard, Christopher Handman, a partner at Hogan Lovells LLP representing rival manufacturers, told the court during oral arguments.
