Narrative
On august 24th, 2022, at approximately 1:00 pm, dominion energy north carolina (denc) responded to a ruptured gas main near the intersection of I-40 and rock quarry road, in raleigh, nc. When the denc first responder arrived, emergency responders had already taken control of the area. The third-party excavator, a subcontractor of the company doing work on the interstate, had pierced the 12-in steel, distribution pressure main while installing sound barrier panels along the interstate row. The excavator did not have a locate ticket. The contractor did call in a locate request after the main had been damaged. The leak was stopped by installing stopper fittings at approximately 12:30 am. Gas blew for approximately 12 hours. Denc management decided to make a PHMSA notification due to the concern that our repair costs would exceed $129,300 and that this event would be considered significant in nature. Repairs have been completed and the line is back in service.
