Project Overview

Columbia Pipeline Group is proposing to construct and operate approximately 165 miles of various diameter pipeline, three new compressor stations, modifications to three existing compressor stations and one regulating station. The Mountaineer XPress project (MXP) would provide an additional 2.7 billion cubic feet per day capacity of firm transportation service from the Marcellus and Utica production areas to markets on the Columbia Gas Transmission system, including markets in western West Virginia, TCO Pool, and other mutually agreeable points. 

The Mountaineer XPress project will facilitate continued use of a domestically-produced, low-cost source of energy that yields significantly lower emissions than its alternatives while reducing the nation’s dependence on foreign providers.

Project Components

In addition the construction of the new pipeline, the project will include the following major components:

  • New compressor stations constructed in Calhoun, Doddridge, and Jackson Counties
  • Modifications to CPG's existing Lone Oak Compressor Station in Marshall County, requiring one new gas-fired compressor unit and piping modifications
  • Modifications to the existing Ceredo Compressor Station in Wayne County requiring two new gas-fired compressor units and piping modifications
  • Modifications to the existing Elk River Compressor Station in Kanawha County requiring one new gas-fired compressor unit and piping modifications

Project Benefits

The Mountaineer XPress Pipeline project is a significant financial investment in the state of West Virginia. According to an economic impact study conducted by Witt Economic LLC, close to 9,000 jobs will be created during the length of this project. In addition to the jobs created, the project will also generate new tax revenue for vital local services

MXP projected expenditures have economic impacts directly on the counties transverse by the pipeline. These counties will benefit from increased property tax revenues both during construction and after the pipeline is placed in service. Upon completion of the project these counties will have a permanent increase in their property tax revenues, which can be used to support county services and local education.

Working Closely with Residents and the Community

Columbia has already begun extensive outreach to landowners and communities in areas where the Mountaineer XPress project will be constructed. Prior to construction, this project will undergo a comprehensive and transparent environmental review overseen by the Federal Energy Regulatory Commission. Throughout the review period, the Mountaineer XPress project team will continue to work closely with landowners, local officials and communities to provide up-to-date information and ensure community involvement in the process.

Focus on Safety and the Environment

In addition to generating substantial local economic benefits, the Mountaineer XPress project will be designed, constructed and operated with a core focus on safety and respect for landowners and local natural resources. Columbia’s efforts to meet and exceed safety and environmental standards have earned the company awards and recognition from the U.S. Fish and Wildlife Service and the American Gas Association.

Columbia anticipates initiating construction in the fall of 2017, with a targeted in-service date of October 31, 2018.
