  • Length: 165 miles / 266 km
  • Status: Operating
  • Start Year: 2018


Mountaineer XPress Gas Pipeline would add 165 miles of pipeline to West Virginia. Mountaineer XPress received its final Environmental Impact Statement (EIS) from the Federal Energy Regulatory Commission (FERC) in July of 2017. As of January 2018, the project has yet to receive additional approvals from other agencies before FERC can issue an authorization for Mountaineer XPress to begin construction.

In October 2018 service began on part of the pipeline, delivering 386 million cubic feet per day (mmcfd).[4]

Environmental Impact

In November 2018 TransCanada's subsidiary Columbia Gas agreed to pay $122,500 for 16 environmental violations that have occurred during construction of the pipeline, including failing to keep sediment-laden water from running off the site, and preventing against erosion.[5]

Expansion Project Background

In January 2019, FERC approved putting an additional 119 miles of the pipeline into service.[4] The exact route remains to be determined.
