Incident Narrative

AT APPROXIMATELY 6:00 PM ON JULY 26, 2011, A PASSING MOTORIST OBSERVED A SPRAY OF OIL AT KPL'S MAYO JUNCTION AND CONTACTED KPL USING THE POSTED EMERGENCY CONTACT INFORMATION. KPL PERSONNEL ARRIVED ON SITE AND CONFIRMED THE RELEASE AT 6:50 PM. CRUDE OIL WAS OBSERVED SPRAYING FROM THE BOTTOM DRAIN PLUG ON THE INGLESIDE TO VIOLA 16"" PIPELINE. KPL CALLED THE PIPELINE CONTROL CENTER TO HAVE THE PIPELINE SHUT DOWN. ONCE THE LINE WAS DOWN AND PRESSURE HAD SUBSIDED, THE VALVE WAS CLOSED STOPPING THE FLOW. A VACUUM TRUCK WAS DISPATCHED AND RECOVERED APPROXIMATELY 6 BARRELS OF CRUDE OIL. KPL'S OIL SPILL RESPONSE ORGANIZATION (OSRO) MILLER ENVIRONMENTAL WAS DISPATCHED FOR CLEAN-UP CREWS AND ROLL OFF BOXES. A PLUG WAS DISCOVERED WHICH HAD BLOWN OUT OF THE BOTTOM OF THE VALVE, APPARENTLY DUE TO INTERNAL CORROSION. A FORMAL INVESTIGATION INTO THE ROOT CAUSE IS PENDING. THE THREADS ON THE VALVE WERE INSPECTED AND A NEW BULL PLUG WAS INSTALLED ON THE VALVE. AFFECTED SOIL WAS EXCAVATED AND PLACED INTO ROLL-OFF BOXES. CONFIRMATION SAMPLES HAVE BEEN TAKEN AND CONFIRMED CLEANUP TO RRC OF TEXAS STANDARDS. BACKFILL AND SOIL DISPOSAL ARE PENDING.
