KOCH PIPELINE COMPANY, L.P.

Incident Narrative

WHILE PERFORMING A ROUTINE MAINTENANCE EXCAVATION ON 1/26/12 TO EXPOSE A BURIED 6"" PROPANE PIPELINE FROM AN IN-LINE INSPECTION TOOL RUN, SMALL BUBBLES WERE DISCOVERED COMING FROM THE SOIL. ONCE THE PIPELINE WAS FULLY EXPOSED, THE SOURCE APPEARED TO BE A PINHOLE IN THE PIPELINE CAUSING A RELEASE FROM THE DOWNSTREAM PART OF A WELD+ENDS. AT THIS LOCATION THERE WERE A PAIR OF WELD+ENDS SEPARATED BY 13 FEET OF CONNECTING PIPE. THE RELEASE WAS LOCATED ON THE UPSTREAM WELD+ENDS. THE RELEASE WAS SO SMALL NO VAPOR CLOUD FORMED. THE MAINTENANCE EXCAVATION WAS LOOKING FOR 2 DENTS THAT WERE SEVERAL FEET AWAY FROM BOTH WELD+ENDS AND THE 13 FEET OF CONNECTING PIPING. PIPELINE WAS IN A NORMAL SCHEDULED SHUTDOWN PRIOR TO THE TIME THE RELEASE WAS DISCOVERED AND PRESSURES WERE STABLE WITHIN A NORMAL OPERATING RANGE. BOTH WELD+ENDS WITH THE 13 FEET OF CONNECTING PIPE WERE REMOVED. THE INVESTIGATION HAS BEEN COMPLETED AND THE CAUSE OF THE RELEASE WAS FROM FILLET WELDING (NO BEVELED EDGE) THAT DID NOT COMPLETELY CLOSE UP ON THE END OF THE WELD+ENDS. AS OF MAY 23, 2014, KOCH PIPELINE COMPANY, L.P. (KPL) IS STILL WAITING FOR AGENCY CLOSURE.
