KOCH PIPELINE COMPANY, L.P.

Incident Narrative

ON SEPTEMBER 29, 2014 AT APPROXIMATELY 16:45, KOCH PIPELINE COMPANY, L.P., (""KPL"") WAS NOTIFIED BY ITS AERIAL PATROL PILOT OF POSSIBLE SHEEN ON THE SURFACE OF A FLOODED PASTURE OVER THE RIGHT-OF-WAY. KPL DISPATCHED LOCAL OPERATORS TO THE SITE AND THE PIPELINE CONTROL CENTER (""PCC"") WAS NOTIFIED. LEAK DETECTION DID NOT INDICATE ANYTHING ABNORMAL, SO THE LINE WAS NOT SHUT DOWN AT THIS TIME. KPL OPERATORS WALKED THE AREA TO DETERMINE IF ANY CRUDE WAS ON OR WITHIN THE VICINITY OF THE RIGHT-OF-WAY. FURTHER, THE OPERATORS CONDUCTED PROBING TO 12""-15"" ON TOP OF THE RIGHT-OF-WAY. THE VISUAL INSPECTION DID NOT INDICATE A RELEASE. ON SEPTEMBER 30, 2014, KPL OPERATORS RETURNED TO THE SITE TO WALK THE VICINITY AND TO COMPLETE FURTHER INVESTIGATION. KPL EXCAVATED AROUND THE PIPELINE. PRODUCT DID NOT POOL IN THE EXCAVATIONS, AND THERE WERE NO INDICATIONS OF A RELEASE. HOWEVER, KPL OPERATING PERSONNEL MADE THE DECISION TO SHUT DOWN THE LINE ON SEPTEMBER 30, 2014 AT 15:52. A SAMPLE OF THE STANDING WATER (WITH SHEEN) WAS COLLECTED BY NAISMITH ENGINEERING (""NEI"") ON SEPTEMBER 30TH, 2014, AND SUBMITTED FOR LABORATORY ANALYSIS. KPL PRESSURE TESTED THE LINE SEGMENT UP TO 49 PSI ON SEPTEMBER 30, 2014 AT APPROXIMATELY 18:17. THE PRESSURE TEST CONTINUED FOR NEARLY 18 HOURS WITH ONLY A 1 PSI PRESSURE DROP. THE RESULTS OF THE PRESSURE TEST DID NOT INDICATE A RELEASE. AFTER EVALUATING THE RESULTS OF THE PRESSURE TEST AND VISUAL INSPECTIONS, THE LINE WAS RESTARTED ON OCTOBER 1, 2014 AT 12:07. DURING THE RESTART, A LEAK WAS DISCOVERED. THE PCC WAS CONTACTED TO SHUT THE LINE DOWN OCTOBER 1, 2014 AT 12:29. THE RESULTS OF THE LABORATORY SAMPLE FROM THE WATER WERE RECEIVED ON OCTOBER 2, 2014 AND INDICATED THE SHEEN ON THE WATER WAS LIKELY COMPOSED OF CRUDE OIL. THE PIPELINE HAS BEEN REPAIRED/REPLACED AND HAS BEEN RESTARTED.
