Daimler Trucks North America, et al. v. EPA

The EPA promulgated an interim final rule (IFR) authorizing it to issue certificates of conformity to diesel truck engines manufacturers for 2012 and 2013 model-year engines notwithstanding the engines did not conform to EPA's emission standard for nitrogen oxides promulgated under section 202(a) of the Clean Air Act (CAA), 42 U.S.C. 7521(a) - provided the manufacturer paid the government a non-conformance penalty (NCP) as established in the IFR. After notice and comment, EPA replaced the IFR with a final NCP rule establishing new and higher NCPs. Daimler petitioned for review of the IFR on both procedural and substantive grounds, as well as EPA's issuance to manufacturer Navistar four 2012 model year certificates of conformity. The court concluded that, with the publication of the Final NCP Rule, Daimler's challenge to the certificates was moot and dismissed the petition for review.
