OGT FIELD OPERATIONS PERSONNEL WORKING AT THE ONEOK GAS STORAGE DEPEW STORAGE FACILITY WERE THE FIRST TO RECOGNIZE THE EVENT AND NOTIFIED GAS CONTROL WITHIN FIVE MINUTES. GAS CONTROL CONFIRMED THIS ALSO WITH THE DATA COMING IN ON THEIR SCADA SCREENS. OGT PERSONNEL WERE DISPATCHED TO THE SITE ARRIVING AT 1120 HOURS. LOCAL LAW ENFORCEMENT AND FIRE DEPARTMENT ALSO RESPONDED. THERE WERE NO FATALITIES OR INJURIES. THE 10.7 MILE PIPE SEGMENT WAS ISOLATED AT 1155 HOURS. NATURAL GAS SERVICE WAS DISRUPTED TO 48 UTILITY CUSTOMERS IN MILFAY AND 13 RURAL FARM TAP CUSTOMERS WERE ALSO IMPACTED. A NEW SECTION OF PIPE WAS INSTALLED AND THE PIPELINE RETURNED TO SERVICE ON JANUARY 9, 2014. UPDATE: THIRD PARTY FAILURE ANALYSIS DETERMINED THE FAILURE WAS CAUSED BY GENERAL AND INTERGRANULAR EXTERNAL CORROSION THAT OCCURRED UNDER COLD APPLIED TAPE COATING. THIS CAUSED A REDUCTION IN THE PIPELINE WALL THICKNESS TO THE POINT THE MATERIAL WAS NO LONGER CAPABLE OF CONTAINING THE GAS PRESSURE AND FAILURE OCCURRED.\n\nPHMSA trend classification: significant incident, not serious.\n\nPHMSA standardized cause: CORROSION — EXTERNAL.\n\nPHMSA indexed costs: $418,165 reported total cost, $242,632.781 in 1984 dollars, $456,441.515 in current-year dollars.\n\nPHMSA trend flags, standardized causes, and indexed costs are analytical fields added to operator-reported incident data. They do not represent final agency causal findings.","truncated":false,"body_characters":2096}
