Incident Narrative
"ON 1/5/2019 AT 20:29, DURING ROUTINE PIGGING OPERATIONS AT THE GEISMAR PUMP STATION, A STUCK PIG WAS DISLODGED AND CAUSED THE PIG TRAP DOOR TO BREAK AWAY FROM THE ENCLOSURE. THE PIGS WERE EJECTED AND PRODUCT RELEASED TO THE ATMOSPHERE. HOUSTON CONTROL CENTER AND LOCAL OPERATIONS CLOSED AUTOMATIC AND MANUAL VALVES NEAR THE GEISMAR STATION. THE PIPELINE WAS DEPRESSURIZED AND THE PIG TRAP AREA WAS ISOLATED. THE PIG TRAP DOOR WAS REPLACED AND TESTING WAS PERFORMED TO ENSURE THE INTEGRITY OF THE ENCLOSURE PRIOR TO THE PIG TRAP BEING RETURNED TO SERVICE. INCIDENT INVESTIGATION IDENTIFIED THAT THE PIGGING PROCEDURE DID NOT CONTAIN GUIDANCE ON HOW TO DISLODGE STUCK PIGS. PART A QUESTION 14A - SHUTDOWN TIME HAS BEEN REVISED TO REFLECT COMPLETE AUTOMATIC VALVE CLOSURE. THE NRC 48-HOUR SUPPLEMENTAL CALL WAS PLACED ON JANUARY 7, 2019; NRC #1234759."
