Federal Energy Regulatory Commission

[Docket No. CP20-48-000]

Iroquois Gas Transmission System, L.P.; Notice of Availability of 
The Final Environmental Impact Statement for The Proposed Enhancement 
by Compression Project

    The staff of the Federal Energy Regulatory Commission (FERC or 
Commission) has prepared a final environmental impact statement (EIS) 
for the Enhancement by Compression Project (Project), proposed by 
Iroquois Gas Transmission System, L.P. (Iroquois) in the above-
referenced docket. Iroquois requests authorization to construct and 
operate natural gas transmission facilities in New York and 
Connecticut. The Project is designed to provide a total of 125,000 
dekatherms per day of incremental firm transportation service for two 
existing customers of Iroquois, Consolidated Edison Company of New 
York, Inc. and KeySpan Gas East Corporation doing business as National 
Grid.
    The final EIS assesses the potential environmental effects of the 
construction and operation of the Project in accordance with the 
requirements of the National Environmental Policy Act. The final EIS is 
not a decision document. It presents Commission staff's independent 
analysis of the environmental issues for the Commission to consider 
when addressing the merits of all issues in this proceeding.
    The final EIS responds to comments that were received on the 
Commission's September 30, 2020 Environmental Assessment (EA) and June 
11, 2021 draft EIS \1\ and discloses downstream greenhouse gas 
emissions for the Project. With the exception of climate change 
impacts, FERC staff concludes that approval of the proposed Project, 
with the mitigation measures recommended in this EIS, would not result 
in significant environmental impacts. FERC staff continues to be unable 
to determine significance with regards to climate change impacts.
---------------------------------------------------------------------------

    \1\ The Project's Environmental Assessment is available on 
eLibrary under accession no. 20200930-3011 and the draft EIS is 
available under accession no. 20210611-3022.
---------------------------------------------------------------------------

    The final EIS incorporates the above-referenced EA, which addressed 
the potential environmental effects of the construction and operation 
of the following Project facilities:
     Athens Compressor Station--installation of one new 12,000 
horsepower (hp) natural gas-fired turbine (Unit A2) in a new building 
with associated cooling, filter separators, and other facilities 
connecting to Iroquois' existing 24-inch-diameter mainline within the 
existing fenced compressor station boundary (Greene County, New York).
     Dover Compressor Station--installation of one new 12,000 
hp natural gas-fired turbine (Unit A2) in a new building with 
associated cooling, filter separators, and other facilities connecting 
to Iroquois' existing 24-inch-diameter mainline and expansion of the 
existing compressor station fenceline within the property boundary 
(Dutchess County, New York).
     Brookfield Compressor Station--construction of a control/
office building, addition of two new 12,000 hp, natural gas-fired 
turbines (Unit B1 and Unit B2) in a new building with associated 
cooling, filter separators, and other typical facilities connecting to 
Iroquois' existing 24-inch-diameter mainline. Additionally, Iroquois 
would install incremental cooling at Plant 2-A to allow for compressed 
discharge gas to be cooled, prior to being compressed at the proposed 
downstream compressors (Units B1 and B2). Iroquois would also replace 
existing turbine stacks on the existing compressor units (Unit-A1 and 
Unit-A2) and add other noise reduction measures (e.g., louvers, seals) 
to minimize existing noise at the site. Modifications at this site 
would require expansion of the existing compressor station fenceline 
within the property boundary (Fairfield County, Connecticut).
     Milford Compressor Station--addition of gas cooling to 
existing compressor units and associated piping to allow for compressed 
discharge gas to be cooled within the current fenced boundaries of the 
existing compressor station, where no gas cooling facilities currently 
exist (New Haven County, Connecticut).
    The Commission mailed a copy of the Notice of Availability of the 
Final Environmental Impact Statement for the Proposed Enhancement by 
Compression Project to federal, state, and local government 
representatives and agencies; elected officials; environmental and 
public interest groups; Native American Tribes; potentially affected 
landowners and other interested individuals and groups; and newspapers 
and libraries in the Project area. The final EIS is only available in 
electronic format. It may be viewed and downloaded from the FERC's 
website (www.ferc.gov), on the natural gas environmental documents page 
(https://www.ferc.gov/industries-data/natural-gas/environment/environmental-documents). In addition, the final EIS may be accessed by 
using the eLibrary link on the FERC's website. Click on the eLibrary 
link (https://elibrary.ferc.gov/eLibrary/search) select ``General 
Search'' and enter the docket number in the ``Docket Number'' field

provides access to the texts of all formal documents issued by the 
Commission, such as orders, notices, and rulemakings.
    In addition, the Commission offers a free service called 
eSubscription that allows you to keep track of all formal issuances and 
submittals in specific dockets. This can reduce the amount of time you 
spend researching proceedings by automatically providing you with 
notification of these filings, document summaries, and direct links to 
the documents. Go to https://www.ferc.gov/ferc-online/overview to 
register for eSubscription.
