Cause detail: A NIGHT PUMPER (CONTRACTOR WORKING FOR THE OPERATOR) ARRIVED AT THE HAWKINSON/WHITMAN PUMP SITE ON THE NIGHT OF 08/30/22 AT APPROXIMATELY 11:50 PM AND DISCOVERED A PUMP PROBLEM. THIS SITE OPERATES TWO 50 BBL PUMPS THAT ARE PIPED TOGETHER, ALTHOUGH ONLY ONE PUMP WAS RUNNING AT THE TIME OF THE INCIDENT. THE CHECK VALVE ON THE DISCHARGE SIDE OF THE INACTIVE PUMP WAS LEAKING AND ALLOWING FLOW THROUGH THE SEAL AND INTO THE SUMP BOX.
