On June 18, 2012, the Environmental Protection Agency (“EPA”) posted in the Federal Register, Vol. 77, No. 117, 36342, its Final Rule adopting several new aircraft engine emission standards for oxides of nitrogen (“NOx”) for aircraft turbofan or turbojet engines with rated thrusts greater than 26.7 kilonewtons (kN), or in common parlance, commercial passenger and freighter aircraft normally used at airports across the United States.  The rule applies only to the manufacture of new aircraft engines, not to retrofit of existing aircraft engines. 

The EPA’s stated purpose in enacting the new rule is two-fold.  First, NOx is strongly correlated with nitrogen dioxide (“NO2”) which is a “criteria pollutant” under the EPA’s National Ambient Air Quality Standards (“NAAQS”), and is an important precursor gas in the formation of ozone and secondary particulate matter (“PM2.5”) which are common air pollutants in urban areas where airports are often located.  Second, the new rule will bring United States’ emissions standards into consistency with those established by the International Civil Aviation Organization (“ICAO”), see ICAO Annex 16, Vol. II, 2010 that the U.S. helped to develop and supports as part of the international process. 

The rule contains six major provisions.

On March 28, 2012, the Environmental Protection Agency (“EPA”) and Department of Justice (“DOJ”) announced their first settlement of an enforcement action addressing Federal Clean Air Act (“CAA”) violations in the marine engine manufacturing and ship building industries.  Under that settlement, Coltec Industries, Inc. (“Coltec”) and National Steel and Shipbuilding Company (“National Steel”) have agreed to pay a civil penalty of $280,000 and spend approximately $500,000 on an environmental project to resolve alleged violations of the CAA and the EPA’s marine diesel engine air rules.  Coltec is a subsidiary of EnPro Industries, Inc. and operates Fairbank Morse Engines which supplies marine propulsion and ship service systems to the United States Navy and Coast Guard.  National Steel is a subsidiary of General Dynamics which designs and builds support ships, oil tankers and dry cargo carriers for the United States Navy and commercial markets.
