TO THE PARTY ADDRESSED: 

 The staff of the Federal Energy Regulatory Commission (FERC of Commission) has 

prepared this final supplemental environmental impact statement (FSEIS) on natural gas pipeline 

facilities proposed by Millennium Pipeline Company, L.L.C. (Millennium), Columbia Gas 

Transmission Corporation (Columbia), Empire State Pipeline and Empire Pipeline, Inc. (Empire), 

Algonquin Gas Transmission System, L.L.C. (Algonquin), and Iroquois Gas Transmission 

System, L.P. (Iroquois) in the above-referenced dockets. Collectively these proposed facilities 

are referred to as the Northeast (NE)-07 Project. 

This FSEIS was prepared to satisfy the requirements of the National Environmental 

Policy Act (NEPA), and it supplements the final environmental impact statement (FEIS) we 

issued for the Millennium Pipeline Project (Docket Nos. CP98-150 et al.) in October 2001. We 

note that other issues and environmental impacts were previously identified in our FEIS issued in 

October 2001. These have been incorporated by reference into this supplement. This FSEIS 

addresses only the issues that were not previously addressed in the 2001 FEIS for the Millennium 

Pipeline Project, such as those arising from newly proposed or modified facilities or facility 

locations, or updated information. 

The purpose of this FSEIS is to inform the public and the permitting agencies about the 

potential adverse and beneficial environmental impacts of the proposed project and its 

alternatives, and recommend mitigation measures that would reduce adverse impacts. The staff 

concludes that approval of the proposed NE-07 Project, with appropriate mitigation measures as 

recommended, would have limited adverse environmental impact. We note that our 

recommended mitigation measures would need to be included in the Commission certificate to 

address aspects of the proposal. 

Proposed Facilities

This FSEIS addresses the potential environmental effects from construction and operation 

of the following proposed facilities in Genesee, Ontario, Yates, Schuyler, Steuben, Chemung, 

Tioga, Broome, Delaware, Sullivan, Orange, Rockland, Putnam, and Dutchess Counties, New 

York; Morris County, New Jersey; and Fairfield and New Haven Counties, Connecticut.

Purpose of Proposed Facilities

The purpose of the proposed NE-07 Project is: 

• for Millennium to provide for the transportation and delivery of about 525,400 Dth/d to 

Millennium’s customers (as opposed to 714,000 Dth/d in the original certificate 

application);

commitment to the U.S. Department of Transportation and the New York Public Service 

Commission to implement an Age and Condition Program to ensure safety and continuity 

of service; 

• for Empire to provide transportation capacity for Canadian gas, and other gas supplies to 

the proposed Millennium Pipeline Project - Phase I at Corning, New York, adding about 

250,000 Dth/d of transmission capacity for downstream markets in the New York City, 

New Jersey, and New England areas; 

• for Algonquin to provide additional capacity via the Ramapo Expansion Project for 

transportation of new gas supply receipts from the Millennium Pipeline Project - Phase I; 

and specifically, to provide 125,000 Dth/d of natural gas transportation capacity for Con 

Edison and 200,000 Dth/d of transportation capacity for KeySpan, and to serve customers 

in the New York natural gas market.

Procedural Notes 

• In accordance with the Council on Environmental Quality’s (CEQ’s) regulations 

implementing NEPA, no agency decision on a proposed action may be made until 30 

days after the U.S. Environmental Protection Agency publishes a Notice of Availability 

of the FSEIS. However, the CEQ regulations provide an exception to this rule when an 

agency decision is subject to a formal internal process which allows other agencies or the 

public to make their views known. In such cases, the agency decision may be made at 

the same time the notice of the FSEIS is published, allowing both periods to run 

concurrently. The Commission decision for this proposed action is subject to a 30-day 

rehearing period. 

 The FSEIS has been placed in the public files of the FERC and is available for public 

inspection at: 

Federal Energy Regulatory Commission 

Public Reference and Files Maintenance Branch
