The staff of the Federal Energy Regulatory Commission will prepare an environmental impact statement (EIS) on the Mountaineer XPress Project (MXP), involving construction and operation of facilities by Columbia Gas Transmission LLC in 14 counties in the western portion of West Virginia.
The commission said in a Nov. 18 notice that it will use this EIS in its decision-making process to determine whether the project is in the public convenience and necessity. Scoping comments on what should be covered in the EIS will be taken until Dec. 17.
Columbia plans to construct and operate approximately 167 miles of 36-inch and 24-inch-diameter pipeline; construct three new compressor stations and three regulator stations; and modify three existing compressor stations and other existing appurtenant facilities in West Virginia. The MXP would provide about 2.7 billion standard cubic feet per day of natural gas transportation capacity from production areas to markets on the Columbia system. Columbia has entered into firm contracts for over 88% of the MXP capacity.
The MXP would consist of the following facilities:
- construction of 161.1 miles of new 36-inch-diameter pipeline and associated equipment (main-line valves, pigging facilities, etc.), located in Marshall, Wetzel, Tyler, Doddridge, Ritchie, Calhoun, Wirt, Roane, Jackson, Mason, Putnam, and Cabell counties, West Virginia;
- construction of 6.3 miles of 24-inch-diamter pipeline in Doddridge County (the Sherwood Lateral);
- construction of three new compressor stations and related equipment in Doddridge County (Sherwood Compressor Station), Ritchie County (White Oak Compressor Station), and Jackson County (Mt. Olive Compressor Station);
- construction of three new regulator stations and associated equipment in Marshall County (the Leach Interconnect), Doddridge County (Sherwood Lateral Regulator), and Cabell County (the Saunders Creek Tie-in);
- replacement of two sections of existing 30-inch-diameter pipeline, 1,295 feet and 814 feet in length, in Cabell County;
- installation of additional compression at the anticipated Lone Oak Compressor Station (Marshall County), Elk River Compressor Station (Wayne County), and Ceredo Compressor Station (Kanawha County) – all of which are under review in other commission dockets; and
- construction and/or installation of other related equipment.
