Incident Narrative
"A 13 GALLON (1 GALLON RECOVERED, 12 GALLONS CLEANED UP) CRUDE OIL RELEASE OCCURRED ON TUE, APR 7 AFTER A MAINLINE PUMP MAINTENANCE (P812). WHEN THE PUMP WAS PUT BACK INTO SERVICE, A 1 INCH BALL VALVE USED TO DRAIN PUMP SUCTION PIPING INTO A SUMP WAS NOT FULLY CLOSED AND CRUDE OIL WAS ENTERING THE DRAIN SYSTEM. CONNECTED TO THE SAME DRAIN PIPING IS A NEARBY METER PROVING LOOP CATCH BASIN WHICH ALSO HAS A 1 INCH BALL VALVE USED TO DRAIN CRUDE OIL TO THE SAME SUMP. THE CATCH BASIN DRAIN VALVE WAS LEFT IN THE OPEN POSITION AND CRUDE OIL BACK-FED THROUGH THE DRAIN PIPING INTO THEN OUT OF THE CATCH BASIN, THIS IS WHERE THE RELEASE OCCURRED. UNDER NORMAL CIRCUMSTANCES, CRUDE OIL WOULD DRAIN TO THE SUMP; HOWEVER, THE SYSTEM WAS SLOW TO DRAIN BECAUSE OF A OBSTRUCTIONS, E.G. PARAFFIN, DEBRIS FROM PUMP DRAINS, ETC."
