West Virginia (AP)—An independent report says the Mountain Valley Pipeline’s test failure in May resulted from a manufacturer defect, not corrosion.
The report says a manufacturer’s defect in an elbow joint caused the May 1 rupture.
A Mountain Valley owner said in a letter that the breach was the only failure during hydrostatic testing of the 303-mile pipeline.
The project began operating in June across rugged mountainsides in West Virginia and Virginia.
Environmental groups, landowners, and some elected officials have long opposed it.
