(Name and address of Applicant)

401 of the Federal Clean Water Act, the State may,

and wildlife, recreation, critical habitats, wetlands
and other natural resources under its jurisdiction.
Procedural and interpretive regulations governing
the scope of the Department’s certification, public
comment, hearings and appeals are in Title 47,
Series 5A.

description which details the activity proposed for
the wetland, river or stream to be affected.

Mountain Valley Pipeline, LLC (Mountain Valley) has
proposed to construct the Mountain Valley Pipeline
Project (Project), a natural gas pipeline that is
approximately 304 miles in length and is 42-inches in
diameter – traversing 11 counties in West Virginia and
six counties in Virginia. The design objective of the
project is to provide timely, cost-effective access to the
growing demand for natural gas for use by local
distribution companies, industrial users, and power
generation facilities in the mid-Atlantic, southeastern,
and Appalachian regions. The proposed project route
would begin at the existing Equitrans, LP transmission
system near the Mobley processing facility in Wetzel
County, West Virginia and extend to the Transco Zone 5
Compressor Station 165 in Pittsylvania County, Virginia.
In addition to the pipeline itself, the project would
nclude three compressor stations facilities, which have
been completed along the route in West Virginia, as well
as other ancillary facilities that are required for the safe
and reliable operation of the pipeline.
While significant efforts were made to avoid wetlands
and streams along the entire route, in select
circumstances there are environmental effects that are
deemed unavoidable. In West Virginia, the proposed
project route would consist of approximately 197 miles
of pipeline, which is roughly 65% of the total pipeline
route, and three compressor stations. The Mountain
Valley project team has proposed to utilize a
125-feet-wide temporary right-of-way to safely construct
the pipeline and a 50-feet-wide permanent right-of-way
in order to properly maintain and safely operate the
pipeline once in-service. Due to the various constraints
of siting and constructing, Mountain Valley anticipates
that the project will have temporary impacts to
approximately 21,107 linear feet of streams and 10.2
acres of wetlands in West Virginia during the
construction phase. Given the size and scope of the
project throughout the state, it is estimated that
approximately 1,116 linear feet of streams and 2.2 acres
of wetlands would be permanently impacted in West
Virginia. Mountain Valley proposes to mitigate all
proposed permanent stream and wetland impacts (lost
or converted) through the use of mitigation bank credits,
including 691 stream mitigation credits and 2.2 wetland
mitigation credits in West Virginia. 

It is anticipated that the Project will have the following:

The designated use of all streams proposed for crossing
¯ Category A – Water Supply
¯ Category B – Propagation and Maintenance of Fish/Other Aquatic Life
¯ Category C – Water Contact Recreation

The designated use for wetlands proposed for crossings (this includes resources that are crossed more than once) are:
¯ Category B-4 – Wetlands: 260 crossings
