As a follow-up to our July 14, 2011 post entitled “EPA Proposes Rule to Set Standards for Nitrogen Oxide Emissions From Aircraft Engines,” on July 27, 2011 the Environmental Protection Agency (“EPA”) published the proposed rule setting nitrogen oxide emissions standards for aircraft engines in the Federal Register (76 Fed. Reg. 45,012). The United Nations’ International Civil Aviation Organization (“ICAO”) has previously endorsed the emissions standards and engine manufacturers have begun conforming to the published standards. The EPA believes that the emissions standards will reduce nitrogen oxide emissions at takeoff and landing by 100,000 tons between 2014 and 2030.

The rule’s release date was July 6, 2011 (130 DEN A-7, 7/7/11) and the EPA will accept comments on the proposed rule through September 26, 2011 at Regulations.gov (Docket Number: EPA-HQ-OAR-2010-0687). A public hearing will be held on August 11, 2011 at the Sheraton Chicago O’Hare Airport Hotel in Rosemont, Illinois at 9:30 a.m. As this issue progresses, please check back to this blog for future posts.
