Incident Narrative

DURING NORMAL STATION ROUNDS ON JANUARY 14, 2019 AT APPROXIMATELY 9:05 FIELD PERSONNEL DISCOVERED A LEAK ON THE INLET VALVE TO THE RECEIPT METER AT BROOKE STATION. CONTROL CENTER WAS NOTIFIED AND THE INBOUND STREAM WAS SHUT DOWN AND THE RECEIPT METER ISOLATED. THE LEAK WAS COMING FROM A CRACKED 3/4"" NIPPLE LOCATED ON THE THERMAL RELIEF AROUND THE METER INLET VALVE BODY. AT APPROXIMATELY 10:37 IT WAS DETERMINED THAT THE REPORTING THRESHOLD FOR VOLUME RELEASED HAD BEEN MET. TX RRC WAS NOTIFIED OF THE RELEASE AND CASE # 1917 WAS ASSIGNED. AFTER THE SYSTEM WAS SHUT DOWN THE METER WAS DRAINED AND LO/TO WAS APPLIED. CLEAN UP OF FREE PRODUCT BEGAN. ALL CONTAMINATED SOIL WAS REMOVED AND REMEDIATED ON SITE. CLEAN BACKFILL WAS BROUGHT IN. THE CRACKED NIPPLE WAS REMOVED. IT WAS DETERMINED THAT THE NIPPLE WAS AN EXTRA FITTING AND NOT REQUIRED FOR THE PROPER OPERATION OF THE THERMAL RELIEF. THE NIPPLE WAS REPLACED WITH AN ALTERNATIVE 1/2"" HEAVIER FITTING ON THE THERMAL RELIEF SYSTEM ON BOTH SIDES OF THE METER INLET VALVE. A SECOND IDENTICAL INLET VALVE WAS INSPECTED AND A SIMILAR NIPPLE INSTALLATION SETUP WAS REPLACED AS DESCRIBED ABOVE. THESE ACTIONS COMBINED WITH DAILY MONITORING BY OPERATIONS PERSONNEL WILL AID IN PREVENTION OF A RECURRENCE. THERE WAS NO INDICATION OF VIBRATION OR OUTSIDE FORCE TO HAVE CAUSED THE NIPPLE FAILURE. THE PIPELINE AND METER WERE RESTARTED AT APPROXIMATELY 14:35. OPERATION WAS MONITORED TO ENSURE ALL REPAIRS WERE SUCCESSFUL AND NO ADDITIONAL LEAKS WERE IDENTIFIED.
