National Environmental Policy Act (NEPA)

The U.S. General Services Administration (GSA) has prepared a Draft Supplemental Environmental Impact Statement (EIS) to analyze the potential impacts from the proposed Master Plan Amendment 2 to the U.S. Department of Homeland Security (DHS) Headquarters Consolidation at St. Elizabeths. The Draft Supplemental EIS has been prepared in accordance with the National Environmental Policy Act (NEPA) of 1969, Council on Environmental Quality Regulations (40 CFR 1500-1508), and GSA Public Buildings Service NEPA Desk Guide. As part of this Draft Supplemental EIS, GSA is also inviting comments on historic preservation concerns under Section 106 of the National Historic Preservation Act, 16 U.S.C. 470 et seq.

The purpose of the Master Plan Amendment 2 is to amend the 2012 Master Plan to accommodate a total of 4.1 million gross square feet (gsf) of secure office and shared-use space and 1.6 million gsf of associated parking on the St. Elizabeths West Campus in Southeast, Washington, DC. The proposed action is needed for efficiency, to reflect the current condition of the historic buildings, to reduce costs, and to accelerate the completion of the DHS consolidation. The Draft Supplemental EIS reviews the impacts and benefits of the Action Alternatives and the No Action Alternative on the human environment. The alternatives are discussed in Chapter 2 of the Draft Supplemental EIS.
