Environmental Impact Statement

The Federal Railroad Administration (FRA) is preparing an Environmental Impact Statement (EIS) in compliance with the National Environmental Policy Act (NEPA) to evaluate the potential impacts on the human and natural environment resulting from the Washington Union Station Expansion Project (the Project). FRA published the Notice of Intent (NOI) to prepare the EIS for the Project in the Federal Register on November 4, 2015.

FRA released the Draft Environmental Impact Statement (DEIS) and Draft Section 4(f) Evaluation for comment from agencies and the public in June 2020.

Following public review of the DEIS, FRA paused the EIS process. During the pause, a new alternative (Alternative F) was developed in response to the 2020 DEIS comments. In July 2022, FRA identified Alternative F as the Preferred Alternative and initiated the preparation of a Supplemental Draft Environmental Impact Statement (SDEIS), Draft Programmatic Agreement (PA), and Draft Section 4(f) Evaluation to assess the potential impacts of this alternative.

On May 12, 2023, FRA released the SDEIS for public and agency comments. Comments on the SDEIS, Draft PA, and Draft 4(f) Evaluation were accepted through July 6, 2023.
