Incident Narrative

ON MAY 6, 2020 AT APPROXIMATELY 10:00 A.M., OPERATIONS PERSONNEL DISCOVERED A SPILL OF CRUDE OIL FROM THE METER SKID AT BARTHOLOMEW PUMP STATION. THE SPILL WAS THE RESULT OF A LOW DRAIN 1"" BALL VALVE BEING OPENED ALLOWING OIL TO FREE FLOW INTO A SITE SUMP WHICH ULTIMATELY OVERFLOWED INTO A SKID PAN. ONCE AT CAPACITY, THE SKID PAN THEN ALLOWED THE FREE-FLOWING OIL TO SPILL ONTO THE LANDSCAPE IN THE FACILITY. DUE TO A RECENT RAINFALL EVENT, THE OIL THEN FLOWED OFFSITE THROUGH A CULVERT INTO A ROADSIDE DITCH BEFORE FINALLY BEING CONTAINED IN A SECTION OF A DRAINAGE DITCH ON AN ADJACENT LANDOWNER'S PROPERTY. AT A LATER TIME ENLINK PERFORMED A ROOT CAUSE ANALYSIS AND REVIEWED ALL PERTINENT DATA AND CONCLUDED, SINCE NO ONE HAD DONE ANY MAINTENANCE OR REPAIRS ON THIS SKID, OPERATOR ERROR WAS NOT A FACTOR. THE FACILITY PERIMETER FENCING SHOWS NO SIGNS OF BREAKING AND ENTERING, RULING OUT SABOTAGE/VANDALISM. THE TEAM DETERMINED THE ROOT CAUSE WAS MORE LIKELY THAN NOT CAUSED BY A FAILED HIGH-LEVEL SUMP SWITCH, ALONG WITH THE VALVE GOING TO ATMOSPHERE NOT BEING PROPERLY LOCKED OR CAR SEALED, ALLOWED PRODUCT TO OVERFILL THE SUMP, IN TURN ALLOWING PRODUCT TO ESCAPE INTO A NEARBY NON-FLOWING DRAINAGE DITCH.
