The FAA last week issued the final environmental impact statement for the New York, New Jersey, Philadelphia airspace redesign, a major project that seeks to reduce delays in and out of the New York and Philadelphia metropolitan areas. While the document doesn’t list a preferred alternative, all indications are that the agency will choose the integrated airspace alternative, the preferred alternative from the draft environmental impact statement issued earlier this year. Regardless of its decision, the agency must wait a minimum of 30 days before issuing the record of decision, which will identify the final preferred alternative. If it’s the integrated airspace alternative, the agency will likely approve further noise mitigation measures. Those measures will lead to the development of routes in and out of airports, including New Jersey’s Teterboro. When pilots will begin flying the new routes is “difficult to forecast” according to an FAA spokesman. The agency still faces a number of legal challenges from area residents upset over noise concerns.
