## Abstract

This action amends the emission standards for turbine engine powered airplanes to incorporate the standards promulgated by the United States Environmental Protection Agency (EPA) on June 18, 2012. This amendment fulfills the FAA's requirements under the Clean Air Act Amendments of 1970 to issue regulations ensuring compliance with the EPA standards. This action revises the standards for oxides of nitrogen and test procedures for exhaust emissions based on International Civil Aviation Organization standards, and for the identification and marking requirements for engines.
