|The new natural gas pipeline
will stretch 109-miles, consisting of 20, 24 and 30-inch diameter
pipeline. The pipeline will carry Marcellus Shale gas from West
Virginia and southwestern Pennsylvania to an interconnection with
Texas Eastern in Westmoreland County, Pennsylvania.
Pipeline route of
Appalachian Gateway Project
from West Virginia
Appalachian Gateway Project also includes four new compressor
stations producing a total of about 17,000 horsepower. Work began on
this project in 2011 with completion set for September 2012.
Dominionís Appalachian Gateway
pipeline will cross under the Monongahela River between Carroll and
Rostraver townships near Charleroi, Pa. Excavation of an underwater
trench beneath the Mon River for the concrete-lined pipe was delayed
in late-2011 by high water.

Appalachian Gateway pipeline can be found further down this page.

JUNE 16, 2011
On June 1, 2010,
Dominion Transmission, Inc. (Dominion) filed an application under
section 7(c) of the Natural Gas Act (NGA) to construct, operate, and
maintain natural gas pipeline and compression facilities in West
Virginia and Pennsylvania. As part of its proposed Appalachian
Gateway Project, Dominion seeks authorization to construct 109 miles
of pipeline, to add four new compressor stations, and to upgrade two
existing compressor stations. Dominion also seeks approval to
integrate its existing TL-263 Expansion Project facilities with
these new facilities and to charge incremental rates for firm
service on the new and existing facilities. The proposed project
will enable Dominion to transport 484,260 dekatherms per day (Dth/d)
from supply areas in West Virginia and Pennsylvania to an
interconnection with Texas Eastern Transmission, LP (Texas Eastern)
in Westmoreland County, Pennsylvania.
to construct and operate the following pipeline segments: (1) TL-570
Ext. 1 - 4.9 miles of 20-inch-diameter pipeline in Kanawha County,
West Virginia, looping an existing Dominion line; (2) TL-492 Ext. 5
- 6 miles of 24-inch-diameter pipe in Greene County, Pennsylvania,
also looping an existing Dominion pipeline; (3) TL-590 - 42.3 miles
of 30-inch-diameter pipeline in Marshall County, West Virginia, and
in Greene County, Pennsylvania; (4) TL-591 - 54.2 miles of
24-inch-diameter pipeline in Greene, Washington, Allegheny, and
Westmoreland Counties, Pennsylvania; (5) TL-596 - 0.5 miles of
16-inch-diameter pipeline in Wetzel County, West Virginia; (6)
TL-597 - 0.1 miles of 10-inch-diameter pipeline in Wetzel County,
West Virginia; (7) TL-598, 0.3 miles of 16-inch-diameter pipeline in
Harrison County, West Virginia; and (8) TL-599, 0.4 miles of
16-inch-diamter pipeline in Harrison County, West Virginia.
proposes to construct and operate the following compression
facilities: (1) the Burch Ridge Station in Marshall County, West
Virginia - a new 6,446 horsepower (hp) facility on the proposed
TL-590 pipeline that will compress gas and enable it to flow back
into Dominionís existing TL-377 pipeline; (2) the Chelyan Station in
Kanawha County, West Virginia - a new 4,735 hp facility at a former
compressor station site; (3) the Morrison Junction Station in
Harrison County, West Virginia - a new 1,775 hp facility to send
gathered gas into Dominionís existing TL-283 pipeline; (4) the Lewis
Wetzel Station in Wetzel County, West Virginia - a new 3,550 hp
facility to receive gas from Dominionís existing TL-283 pipeline and
send it into its existing TL-430 pipeline; (5) the Schutte Station
in Doddridge County, West Virginia - an existing facility to be
upgraded by recylindering an existing unit; and (6) the Pepper
Station in Barbour County, West Virginia - a new 1,775 hp
transmission compressor unit at an existing gathering compressor
do not oppose the proposed project, but raise concerns which they
state will be satisfied if the Commission requires Dominion to
implement mitigation and monitoring measures to ensure that the
proposed pipeline will not significantly conflict with, or be
affected by, past, present, or future subsurface mining activities.
Protesting parties raise similar concerns.
