Location detail: 10.55

Cause detail: EXCAVATION DAMAGE BY THIRD PARTY

Cause detail: LOCATING ISSUE

Cause detail: FACILITY NOT MARKED DUE TO INCOMPLETE MARKS AT DAMAGE LOCATION

Cause detail: CONTRACTOR, WHO WAS CLEANING DITCH BY EXCAVATION, GRABBED A ONE-INCH TAP VALVE WHICH PULLED THE THREADS CAUSING LEAK. 2-15-18 REVISE PER PHMSA'S INSTRUCTIONS. *APPROXIMATELY 10-1-2015, RANDY'S DIRT SERVICES (WICKOFF DRAINAGE DISTRICT/CITY OF) APPARENTLY DAMAGED A 1" BRANCH CONNECTION. *ON 3-2-16 AT 16:15, FARMER NOTIFIED GULF SOUTH OF POTENTIAL LEAK. *ON 3-2-16 AT 16:20, LEAK CONFIRMED AND CONFIRMED DISCOVERY THAT REPORTING CRITERIA WAS MET (SINCE SMALL GAS LEAK OF UNKNOWN DURATION, ASSUMED 3 MMCF GAS LOSS). DUE TO THE LIMITED NATURE OF GAS LOSS COMING THROUGH THE 1" BRANCH CONNECTION, PRESSURE WAS LOWERED BY 20% AND REPAIR WAS SCHEDULED. *ON 3-4-16 AT 13:00, PIPELINE WAS SHUT DOWN AND REPAIRED. 3-5-2018 REVISE IN RESPONSE TO PHMSA EMAIL. GULF SOUTH ASSUMES THAT THE DAMAGE TO THE PIPE OCCURRED AS PART OF EXCAVATION THAT OCCURRED ON 10-1-2015, BUT THAT IS ONLY AN ASSUMPTION. IN OUR OPINION, THE SUB-CAUSE IS BY PREVIOUS DAMAGE DUE TO EXCAVATION. BASED ON THE FACT THAT WE ASSUME POSSIBLE LEAKAGE OCCURRED AS EARLY AS 10-1-2015, GULF SOUTH ASSUMED THE GAS LOSS EXCEEDED 3 MMCF, THEREFORE, CREATING AN INCIDENT. THE DATA PROVIDED IS ATTEMPTING TO REFLECT THIS UNDERSTANDING OF THIS INCIDENT. A PIPELINE MARKER WAS LOCATED WITHIN APPROXIMATELY 10-FEET OF THE DAMAGED PIPE. 5-2-18 REVISE IN RESPONSE TO PHMSA EMAIL. GULF SOUTH'S ASSETS WERE CLEARLY MARKED WITH PIPELINE MARKERS BUT THE ONE CALL WAS IMPROPERLY CLEARED. THE ONE CALL TICKET WAS RECEIVED ON 10-1-2015 AND THE POSITIVE RESPONSE WAS DELIVERED ON 10-2-2015 SO THE BEST SPECULATION IS THAT THIS INCIDENT OCCURRED ON 10-2-2015. RESPONSES TO PART G HAVE BEEN REVISED TO PROPERLY REFLECT THIS. PART A HAS BEEN REVISED TO REFLECT THAT THE DATE AND TIME OF THE INCIDENT WAS 10-2-2015 WHEN WE BELIEVE THE DAMAGE LIKELY OCCURRED. THE TIME IS 12:00 BECAUSE WE HAVE NO WAY TO DETERMINE THE CORRECT TIME SINCE WE DIDN'T KNOW UNTIL 3-2-2016 THAT DAMAGE HAD OCCURRED.
