Final Environmental Impact Statement (FEIS) Details – Published August 11, 2005
The Federal Aviation Administration (FAA) has published the Final Environmental Impact Statement (FEIS) for two new air carrier runways, terminal facilities and other related improvements at Washington Dulles International Airport (IAD). The document is available for review online or at several regional locations listed below.

The Metropolitan Washington Airports Authority (MWAA) proposes to construct additional north-south and east-west runways, parallel and connector taxiways, and a Tier 3 concourse; extend the Automated People Mover System; enhance navigational aids and develop other associated projects.

FAA evaluated two Build Alternatives and a No-Build Alternative in the FEIS. The FEIS documents the need for additional airport infrastructure to satisfy the forecast aviation demand, analyzes multiple alternatives, including a No-Build Alternative, and identifies FAA’s Preferred Alternative (Build Alternative 3) for the proposed project at Dulles. The FEIS includes a Mitigation Program for the Preferred Alternative that describes ways that MWAA will minimize and/or mitigate for the environmental impacts associated with the Preferred Alternative. The FEIS also contains the Final Air Quality General Conformity Determination, the Preliminary Final Section 106 Report, a Coastal Zone Consistency Determination, and a finding of an unavoidable, non-significant encroachment (with mitigation) on the base 100-year floodplain.
