The Federal Energy Regulatory Commission allowed Columbia Gas Transmission LLC to extend construction work to finish its 2.7-Bcf/d Mountaineer XPress natural gas system expansion, but not by as much as the company requested.
In a Feb. 15 letter, FERC granted the TransCanada Corp. subsidiary authorization to extend regular construction activities to 7 a.m. to 10 p.m. ET seven days a week at the Sherwood, White Oak, Mount Olive, Lone Oak, Ceredo and Elk River compressor station sites. The commission found that the request complied with an environmental condition of its December 2017 certificate order.
Columbia Gas received much of what it asked for, but not all. In letters to FERC in early February, the company requested permission to work 24/7 at the site of the Mount Olive compressor station to meet an in-service target for the more than $2 billion project in the fourth quarter.
In late January, FERC gave Columbia Gas approval to begin construction on three compressor stations, including Mount Olive, as well as nonmechanized tree clearing in upland areas. FERC approved the project, along with affiliate Columbia Gulf Transmission LLC's approximately $674 million Gulf XPress gas project, at the end of December 2017.
Mountaineer XPress is designed to deliver gas to Columbia Gulf at a Leach, Ky., interconnect and to the TCO Pool hub on the Columbia Gas system. The project will consist of 164.5 miles of new 36-inch-diameter pipeline running through Marshall, Wetzel, Tyler, Doddridge, Ritchie, Calhoun, Wirt, Roane, Jackson, Mason, Putnam and Cabell counties in West Virginia; six miles of new 24-inch-diameter pipeline in Doddridge County; 0.4 mile of 30-inch-diameter replacement pipeline on a line in Cabell County; and abandonment of segments of the line.
The project would also include bidirectional tie-in facilities in Marshall and Doddridge counties; new compressor stations in Doddridge, Calhoun and Jackson counties; and modifications to compressor stations in Marshall, Wayne and Kanawha counties in West Virginia. (FERC docket CP16-357)
