Incident Narrative
"ON MAY 12TH AT 0555, THE PIPELINE SUPERVISOR SENT OPERATIONS PERSONNEL TO INVESTIGATE A LEAK INDICATION. AT AROUND 0630, A POSSIBLE GAS LEAK WAS VISUALLY IDENTIFIED AND OPERATIONS PROCEEDED TO ISOLATE THE PIPELINE. BY 0707, THE DOWNSTREAM AND UPSTREAM MANUAL VALVES WERE CLOSED, ISOLATING THE PIPELINE. AT 0900, OPERATIONS WAS ABLE TO SAFELY APPROACH THE LEAK SITE AND DETERMINED THE LEAK SIZE AND ORIGIN. BASED ON THE SIZE OF THE LEAK, ENTERPRISE CALCULATED THAT THE RELEASE VOLUME EXCEEDED 3 MMSCF AND THE NRC WAS IMMEDIATELY NOTIFIED. ON MAY 13TH LINE 15 WAS EXCAVATED AND ENTERPRISE CONFIRMED THE RELEASE WAS DUE TO A FAILURE OF A 3RD PARTY CHECK VALVE CAP. THE CHECK VALVE WAS REMOVED AND THE CONNECTION WAS CAPPED."
