On June 10, 2009, the U.S. Court of Appeals for the District of Columbia Circuit denied twelve consolidated petitions challenging the FAA’s decision to redesign the airspace surrounding airports in New York, New Jersey, and Philadelphia.  In an unpublished opinion, the court in County of Rockland v. FAA rejected each of the claims presented by the petitioners, including arguments based on NEPA, the Department of Transportation Act Section 4(f), and the Clean Air Act.
