In a letter sent to the U.S. Army Corps of Engineers, West Virginia’s West Virginia’s Department of Environmental Protection announced it has withdrawn a water quality certification previously issued in March for the Mountain Valley Pipeline.
“This decision will allow the agency to re-evaluate the complete application to determine whether the state’s certification is in compliance with Section 401 of the federal Clean Water Act,” said Scott Mandirola, Director of the DEP’s Division of Water and Waste Management.
The decision comes shortly before West Virginia was prepared to take legal action asking the U.S. Court of Appeals for the Fourth Circuit to uphold the certification.
The Mountain Valley Pipeline is a natural gas pipeline system that will span approximately 303 miles from northwestern West Virginia to southern Virginia and will be constructed and owned by Mountain Valley Pipeline, LLC, a joint venture between EQT Midstream Partners, LP, NextEra US Gas Assets, LLC, Con Edison Transmission, Inc., WGL Midstream, and RGC Midstream, LLC. EQT Midstream Partners will operate the pipeline and own a majority interest in the joint venture.
Once completed, the Mountain Valley Pipeline is expected to provide up to two million dekatherms per day of firm transmission capacity to markets in the Mid and South Atlantic regions of the United States. The pipeline will extend from the Equitrans transmission system in Wetzel County, West Virginia, to Transcontinental Gas Pipeline Company’s Zone 5 compressor station 165 in Pittsylvania County, Virginia.
