Location detail: 3.70 Cause detail: PREVIOUS DAMAGE DUE TO EXCAVATION ACTIVITY Cause detail: MISCELLANEOUS ROOT CAUSES Cause detail: PREVIOUS DAMAGE Cause detail: TENNESSEE GAS PIPELINE (TGP) COMPANY'S GAS CONTROL BEGAN RECEIVING PHONE CALLS FROM LAND OWNERS ABOUT A PIPELINE RUPTURE IN THE COMMUNITY OF TRAPP NEAR CLAY CITY, KY, SHORTLY AFTER MIDNIGHT ON SEPTEMBER 21, 2011. RESPONDING TGP PERSONNEL DISCOVERED THAT A FAILURE HAD OCCURRED IN THE HOWARD CREEK CROSSING ON LINE 100-2 AT 105-2+3.70. POST INCIDENT INVESTIGATION REVEALED THAT EXCAVATION EQUIPMENT HAD BEEN USED A FEW DAYS PRIOR TO THE INCIDENT AT THE CREEK CROSSING. MARKS ON THE PIPE INDICATED STRIKES BY THE EXCAVATION EQUIPMENT, LEAVING GOUGES ON THE PIPE'S SURFACE. METALLURGICAL ANALYSIS CONFIRMED THE INITIAL FIELD CONCLUSION THAT THE FAILURE RESULTED FROM MECHANICAL DAMAGE TO THE PIPE. THE FAILED PIPELINE HAS NOT BEEN REPAIRED. SINCE IT IS NOT NEEDED FOR MAINTAINING SERVICE UNDER CURRENT LOAD DEMANDS, REPAIR IS DELAYED UNTIL OPPORTUNITY FOR FAVORABLE WEATHER. PHMSA trend classification: significant incident, not serious. PHMSA standardized cause: EXCAVATION DAMAGE — PREVIOUS DAMAGE DUE TO EXCAVATION. PHMSA indexed costs: $198,100 reported total cost, $138,557.044 in 1984 dollars, $171,849.019 in current-year dollars.
