CHARLEROI, PA Ė As Marcellus Shale gas production has increased, various companies have begun to install new pipelines to move the methane and gas liquids out of the tri-state area near Pittsburgh.
FERC, the Federal Energy Regulatory Commission, approved Dominion Transmissionís Appalachian Gateway Project on June 16, 2011.

Dominion activates W.Va. gas pipeline

September 5, 2012 - Officials with Virginia-based Dominion announced the activation of the company's Appalachian Gateway Project, which will send gas from the Ohio Valley to markets along the Eastern Seaboard. The pipeline project consists of 110 miles of 20-inch, 24-inch and 30-inch diameter pipeline. The Appalachian Gateway Project will transport natural gas produced in West Virginia and southwest Pennsylvania to where it can be sold to customers in the Northeast and Mid-Atlantic. Source: The Intelligencer

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.

Appalachian Gateway Project near Charleroi PennsylvaniaThe 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.

EXCERPTS FROM FERC DOCUMENT
JUNE 16, 2011

Docket No. CP10-448-000

Complete document:

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.

Dominion proposes 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.

Dominion also 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 station.

Alpha Companies 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.
