UNITED STATES OF AMERICA
FEDERAL ENERGY REGULATORY COMMISSION
Mountain Valley Pipeline, LLC.
Docket No. CP19-14-000
NOTICE OF AVAILABILITY OF THE
FINAL ENVIRONMENTAL IMPACT STATEMENT FOR THE PROPOSED
SOUTHGATE PROJECT
(February 14, 2020)
The staff of the Federal Energy Regulatory Commission (FERC or Commission),
with the participation of the cooperating agencies listed below, has prepared a final
environmental impact statement (EIS) for the Southgate Project (Project) proposed by
Mountain Valley Pipeline, LLC. (Mountain Valley) in the above -referenced docket.
Mountain Valley requests authorization to construct and operate about 75.1 miles of natural
gas transmission pipeline, one new compressor station, and accompanying facilities that
would provide about 375 million cubic feet per day of available capacity for transport from
the City of Chatham, in Pittsylvania County, Virginia to a delivery point with Dominion
Energy North Carolina (DENC), formerly PSNC, 1 near the City of Graham in Alamance
County, North Carolina.
The final EIS assesses the potential environmental effects of the construction and
operation of the Southgate Project in accordance with the requirements of the National
Environmental Policy Act (NEPA). As described in the final EIS, the FERC staff concludes
that approval of the Project would result in some adverse environmental impacts; however,
these impacts would be reduced to less -than -significant levels because of the impact
avoidance, minimization, and mitigation measures proposed by Mountain Valley and those
recommended by staff in the EIS.
The United States Army Corps of Engineers (COE) and the U.S. Department ofthe
Interior Fish and Wildlife Service (FWS) participated as cooperating agencies in
preparation of this EIS. Cooperating agencies have jurisdiction by law or special expertise
with respect to resources potentially affected by the proposal and participate in the NEPA
analysis. The cooperating agencies provided input into the analyses, conclusions, and
recommendations presented in the EIS. Following issuance of the final EIS, the
cooperating agencies will issue subsequent decisions, determinations, permits, or
authorizations for the Project in accordance with each individual agency's regulatory
requirements.
Following a January 2, 2019 merger, Dominion Energy, Inc. acquired PSNC and changed the company
name to Dominion Energy North Carolina.

Docket No. CP19-14-000
The COE would use this EIS in their regulatory process, and to satisfy compliance
with NEPA and other related federal environmental laws (e.g., the National Historic
Preservation Act).
The EIS addresses the potential environmental effects of the construction and
operation of the following project facilities:
' J • about 75.1 miles of new 24-inch and 16-inch diameter natural gas pipeline
located in Pittsylvania County, Virginia, and Rockingham and Alamance
Counties, North Carolina;
• one new 28,915 horsepower compressor station (Lambert Compressor
Station) in Pittsylvania County, Virginia;
• four interconnects or tie-ins with facilities operated by Mountain Valley, East
Tennessee Gas, and DENC; and
• ancillary facilities including pig launchers and receivers, mainline block
valves (MLV), and cathodic protection beds.
The Commission mailed a copy of the Notice of Availability of the final EIS to
federal, state, and local government representatives and agencies; elected officials;
environmental and public interest groups; Indian Tribes; potentially affected landowners
and other interested individuals and groups; and newspapers and libraries in the area of the
Project. The final EIS is available in hard copy at libraries in the area of the Project and in
electronic format. It may be viewed and downloaded from the FERC's website
(www.ferc.gov), on the Environmental Documents page
(https://www.ferc.gov/industries/gas/enviro/eis.asp). In addition, the final EIS may be
