navistar and epa timeline
2001: The Environmental Protection Agency enacted a rule requiring a 95 percent reduction in the emissions of nitrogen oxide from heavy-duty diesel engines. Manufacturers have until 2010 to comply.
2004: The EPA patented a heavy-duty diesel engine process to reduce emissions through a Cooperative Research and Development Agreement with Navistar. Navistar pays undisclosed licensing fees to use this technology.
2010: Manufacturers’ engines must comply with the EPA’s emissions policies. Navistar’s new engine still does not meet requirements, so they use banked emissions credits to buy more time.
2011: At the end of 2011, Navistar announced it will run out of banked emissions credits in 2012 and the engines still are not compliant.
January 2012: The EPA passes a rule to permit manufacturers of heavy-duty diesel engines to pay nonconformance penalties in exchange for the right to sell noncompliant engines.
May-June 2012: A group of petitioners led by Mack Trucks Inc. sued the EPA, arguing that the fines Navistar pays are too lenient and that they were not given notice of the ruling before they became compliant with emissions regulations. The court ruled against the EPA, which now must re-evaluate their noncompliance penalties.
