Narrative
A contractor crew performing directional boring for water main work struck a 6-inch plastic gas distribution main during pull-back of a reaming tool. The location of the gas main had not been verified prior to the work. Dte gas emergency response personnel stopped the leaking gas from the east by installing a line stopper pressure control fitting on a 12-inch section of main, and from the west by pinching the 6-inch plastic main. Leaking gas was stopped at 23:23, some 13 hours after the damage. Repairs were completed at 04:30 on december 17, 2015, using 3 feet of new 6-inch plastic pipe and two electrofusion couplings.
