"AT APPROXIMATELY 2:15 AM, AT DCP MIDSTREAM WILBREEZE PUMP STATION LOCATED NEAR EDNA, TX, THE SHUTDOWN VALVE ESD120 INADVERTENTLY WENT CLOSED CAUSING A THERMAL RELIEF VALVE TO LIFT AND VENT APPROXIMATELY 34.6 BARRELS OF NGL TO ATMOSPHERE. THE OPERATOR AT THE HOUSTON CONTROL CENTER CALLED AN NGL TECHNICIAN AT APPROXIMATELY 2:30 AM TO INVESTIGATE. THE NGL TECHNICIAN ARRIVED AT THE SITE AT 3:20 AM AND BEGAN TO INVESTIGATE THE CLOSURE AND RETURNED THE VALVE TO THE OPEN POSITION. AT APPROXIMATELY 3:30 AM, THE TECHNICIAN SAW A FLAME ON TOP OF THE VENT STACK. IT IS PRESUMED THAT STATIC ELECTRICITY OR A LIGHTNING STRIKE FROM A STORM IN THE AREA IGNITED THE NGL VAPORS ON TOP OF THE VENT STACK.
