A major U.S. natural gas pipeline project has been delayed again as developer Equitrans Midstream Corp. pursues new permits for the troubled conduit.
The Mountain Valley Pipeline is now estimated to start up in the second half of 2023 and will cost $6.6 billion, the company said Tuesday in a statement. That’s up from a previous forecast of $6.2 billion. Until late last year, Equitrans expected the pipeline to start operating by this summer. It was originally expected to be in service in 2018, and the cost estimate has roughly doubled since the project was announced in 2014.
