Dulles Environmental Studies
The Metropolitan Washington Airports Authority (Airports Authority) is currently undertaking a capital improvement program, called d2, to provide new facilities and replace and upgrade existing aircraft, passenger, and support facilities at Washington Dulles International Airport.
Several separate studies look at the potential environmental impacts of three major proposed project groups: 1) a new concourse, a new airport passenger train system, and associated projects that will replace the existing Concourse C/D complex and the mobile lounge shuttles; 2) a replacement, modernized airport traffic control tower; 3) and two new runways and associated projects.
The studies are prepared in compliance with the National Environmental Policy Act (NEPA) of 1969, as amended, the regulations of the President's Council on Environmental Quality (CEQ) for NEPA compliance, and Federal Aviation Administration (FAA) Orders 1050.1E and 5050.4A. NEPA requires federal agencies to consider a wide array of potential environmental effects when proposing actions including: noise; compatible land use; social and socioeconomic characteristics; air quality; water quality; geology and soils; historic, architectural, archaeological, and cultural resources; biotic communities; endangered and threatened species; wetlands; floodplains; coastal zone management; coastal barriers; wild and scenic rivers; prime and unique farmland; energy; light emissions; visual aesthetics; solid waste, hazardous waste, and pollution prevention; and design, art, and architecture. These studies are decision-making tools that analyze the potential environmental effects of a proposed action and its alternatives and provide a forum to address both regulatory and public concerns.
