The DEIS evaluates the environmental, economic, cultural, and social Fact Sheet # 1 – Project Overview impacts of the proposed Project’s alternatives. It discloses a Project's Fact Sheet # 2 – Scoping Process economic, environmental, and social impacts in order to inform the public as well as the agency's decision making in choosing an Fact Sheet # 3 – Preferred Alternative Alternative to implement. Details of the Preferred Alternative can be found on the Project website at www.hudsontunnelproject.com. Public participation is a critical part of the environmental review process required by NEPA. A DEIS is now available for public review and comment. Public hearings will be held during the public comment period, and comments may also be submitted via the Project website, via email and by mail. The public comment period will continue until August 21, 2017. After the public comment period on the DEIS closes, FRA and NJ TRANSIT will consider all comments and will prepare a Final EIS (FEIS).
