Cause detail: APPROXIMATELY 0.26 BBLS OF CRUDE OIL WERE RELEASED AS A RESULT OF A ROOF DRAIN FAILURE, INSIDE OF A TANK, AT PLAINS TEN MILE FACILITY. PLAINS OPERATOR IMMEDIATELY ISOLATED BOTH ROOF DRAINS UPON DISCOVERY. THE FAULTY ROOF DRAIN WILL REMAIN LOCKED OUT AND ISOLATED UNTIL THE TANK CAN BE REMOVED FROM SERVICE FOR FURTHER INVESTIGATION AND REPAIRS. PART C, NUMBER 2 WAS REVISED FROM TERMINAL/TANK FARM TO BREAKOUT TANK OR STORAGE VESSEL. SUPPLEMENTAL NARRATIVE: THE TEN MILE TANK REFERENCED IN THE REPORT IS STILL IN SERVICE AS OF 8/22/2018. THE ROOF DRAIN THAT LEAKED IS ONE OF TWO THAT THE TANK CURRENTLY HAS, TO REMOVE WATER FROM THE ROOF. THE 4' DRAIN IS THE DRAIN THAT LEAKED, BUT THE TANK HAS A 6' DRAIN CURRENTLY IN SERVICE. THERE ARE ALSO SECONDARY PUMPS WHICH WILL REMAIN ON THE ROOF IN CASE OF AN EMERGENCY. THE PUMP LINES RUN TO FRAC TANKS POSITIONED NEXT TO THE TANK. PLAINS DOES NOT FEEL THERE IS AN IMMEDIATE NEED TO REMOVE THE TANK FROM SERVICE DUE TO THE WORKING ROOF DRAIN AND SAFETY PRECAUTIONS PUT IN PLACE TO MITIGATE RAIN OR AN EMERGENCY. WE WILL NOT KNOW THE ROOT CAUSE OF THE FAILURE UNTIL THE TANK IS TAKEN OUT AND REPAIRS ARE MADE. THE TANK WILL REMAIN IN SERVICE UNTIL EITHER THE SCHEDULED OOS 653 INSPECTION IN APRIL 2024, OR UNTIL IT IS DEEMED AN APPROPRIATE TIME TO TAKE IT OUT.
