"ON AUGUST 9, 2019 AT APPROXIMATELY 14:28 HOURS CONSUMERS ENERGY WAS NOTIFIED OF DAMAGE TO A 6"" STEEL MEDIUM PRESSURE NATURAL GAS PIPELINE LOCATED NEAR 3340 W. TIENKEN, ROCHESTER HILLS, MICHIGAN (OAKLAND COUNTY). A CONSUMERS ENERGY GAS SERVICE WORKER (GSW) ARRIVED AT APPROXIMATELY 14:50 HOURS CONFIRMING DAMAGE TO THE PIPELINE AND REQUESTED A DISTRIBUTION CREW. THE DAMAGE LOCATION AND SURROUNDING AREAS WERE CONTINUOUSLY MONITORED UNTIL REPAIRS WERE COMPLETED. FURTHER INVESTIGATION DETERMINED A CONTRACTOR BORING CONDUIT FOR ELECTRIC HAD PREVIOUSLY EXPOSED AND SUCCESSFULLY CROSSED THE PIPELINE. HOWEVER DURING THE PULL BACK THEIR BORE SHOT APPEARED TO FLEX UPWARD RESULTING IN LOSS OF CLEARANCE AND SUBSEQUENT DAMAGE TO THE NATURAL GAS PIPELINE. THE DISTRIBUTION CREW ARRIVED ONSITE AT APPROXIMATELY 16:57 HOURS. MUELLER CONTROL FITTINGS WERE INSTALLED TO ISOLATE THE DAMAGE SEGMENT AND A PLIDCO BOLTED SPLIT SLEEVE FITTING USED AS A TEMPORARY REPAIR.
