Mountain Valley Pipeline, LLC; Notice of Schedule for the
Preparation of an Environmental Assessment for the Mountain Valley
Pipeline Boost Project
On October 23, 2025, Mountain Valley Pipeline, LLC (Mountain
Valley) filed an application in Docket No. CP26-14-000 requesting a
Certificate of Public Convenience and Necessity pursuant to Section
7(c) of the Natural Gas Act to construct and operate certain natural
gas pipeline facilities. The proposed project is known as the Mountain
Valley Pipeline Boost Project (Project) and would provide about 600,000
dekatherms of natural gas per day from interconnection points with
Equitrans, L.P. and EQM Gathering Opco, LLC to delivery points on the
Mountain Valley Pipeline Mainline system and Mountain Valley Pipeline
Southgate system.
On November 5, 2025, the Federal Energy Regulatory Commission
(Commission or FERC) issued its Notice of Application for the Project.
Among other things, that notice alerted agencies issuing federal
authorizations of the requirement to complete all necessary reviews and
to reach a final decision on a request for a federal authorization
within 90 days of the date of issuance of the Commission staff's
environmental document for the Project.
This notice identifies Commission staff's intention to prepare an
environmental assessment (EA) for the Project and the planned schedule
for the completion of the environmental review.\1\ The EA will be
issued for a 30-day comment period.
---------------------------------------------------------------------------
\1\ For tracking purposes under the National Environmental
Policy Act, the unique identification number for documents relating
to this environmental review is EAXX-019-20-000-1767605403.

---------------------------------------------------------------------------
\2\ The Commission's deadline applies to the decisions of other
federal agencies, and state agencies acting under federally
delegated authority, that are responsible for federal
authorizations, permits, and other approvals necessary for proposed
projects under the Natural Gas Act. Per 18 CFR 157.22(a), the
Commission's deadline for other agency's decisions applies unless a
schedule is otherwise established by federal law.
If a schedule change becomes necessary, additional notice will be
provided so that the relevant agencies are kept informed of the
Project's progress.
Project Description
Mountain Valley proposes to make modifications to three existing
compressor stations (CS) and construct and operate the new Swann CS.
The Project would consist of the following facilities:
<bullet> installation of one additional natural gas turbine and
auxiliary facilities to add an additional 23,470 horsepower (hp) to the
Bradshaw CS in Wetzel County, WV;
<bullet> relocation of existing blowdown silencers and installation
of one additional natural gas turbine and auxiliary facilities to add
an additional 52,500 hp to the Harris CS in Braxton County, WV;
<bullet> relocation of existing blowdown silencers and installation
of two additional natural gas turbines and auxiliary facilities and
upgrades to two existing natural gas turbines to add an additional
52,880 hp to the Stallworth CS in Fayette County, WV;
<bullet> installation of a new compressor station with three
natural gas turbines, for a total of 136,900 hp at the Swann CS in
Montgomery County, VA; and
<bullet> installation of a new pig launcher and receiver,\3\
mainline valve, and auxiliary facilities at the Swann CS.

Background
On November 19, 2025, the Commission issued a Notice of Scoping
Period Requesting Comments on Environmental Issues for the Proposed MVP
Boost Project (Notice of Scoping). The Notice of Scoping was sent to
affected landowners; federal, state, and local government agencies;
elected officials; environmental and public interest groups; Native
American tribes; other interested parties; and local libraries and
newspapers. In response to the Notice of Scoping, the Commission
received comments from 11 non-governmental organizations, five
municipalities, two counties, four state agencies, one federal agency,
three companies, six state-elected officials, one Congressmember, and
more than 80 individuals. The primary issues raised by the commenters
are concerns regarding groundwater, waterbodies, wildlife, traffic, air
emissions, noise and vibration effects, compressor station site and
facility alternatives, pipeline safety associated with the increased
capacity, human health, climate change, segmentation, and the length of
the

scoping comment period. All substantive comments will be addressed in
the EA.
The U.S. Army Corps of Engineers, Huntington District, is a
cooperating agency in the preparation of the EA.
