Incident Narrative

**THIS A SUPPLEMENTARY REPORT TO UPDATE THE TOTAL DAMAGE AND REPAIR COST IN PART D.2. A TYPO WAS ALSO FOUND IN THE 1-CALL TICKET NUMBER FOR THE WORK IN PART G3.9, THE REPORT INCORRECTLY STATED 2014062791 WHEN IT SHOULD HAVE BEEN 2018062791. THIS SUPPLEMENTARY REPORT WILL BE THE LAST REPORT FILED FOR THIS EVENT. ** A CONTRACTOR WAS INSTALLING A NEW GAS PIPELINE TO REPLACE AN EXISTING GAS PIPELINE. THE CONTRACTOR HIT A SERVICE LINE, AND PULLED THE SERVICE TAP OFF THE EXISTING MAIN. THREE HOUSES IN THE VICINITY OF THE LINE HIT WERE EVACUATED AND ELECTRIC POWER WAS SHUT OFF. VALVES COULD HAVE BEEN CLOSED TO PROMPTLY ISOLATE THE LEAK, AND IF THIS WAS DONE, THE INCIDENT REPORTING CRITERIA WOULD NOT HAVE BEEN MET. CLOSING VALVES WOULD HAVE RESULTED IN LOSS OF GAS SERVICE TO OVER 2000 CUSTOMERS INCLUDING 2 HOSPITALS. UGI MADE THE DECISION TO ALLOW THE GAS TO VENT TO A SAFE AREA WHILE A TEMPORARY BYPASS WAS INSTALLED. THE NRC WAS CALLED WHEN GAS LOSS CALCULATIONS INDICATED THAT OVER 3000 MCF WOULD BE VENTED. THE COST OF INSTALLING THE BYPASS ALSO EXCEEDED $50,000.
