Incident Narrative

AT 15:34, THE CONTROL CENTER CONTROLLER NOTICED THE MANCHESTER DISCHARGE PRESSURE HAD DROPPED. WITHIN 2 MINUTES THE CONTROLLER RECIEVED THE FIRST SUMP LEVEL INDICATION. THE DISCHARGE PRESSURE COUPLED WITH THE SUMP HAD ALL INITIAL INDICATIONS OF A LEAK. THE CONTROLLER IMMEDIATELY TRENDED THE FLOW OUT OF MANCHESTER, BOTH AT THE METER AND THE GILLIS CHECK. THERE WAS A SLIGHT GAIN AT THE MANCHESTER METER, AND SLIGHT DROP AT THE GILLIS CHECK METER. WITHIN THE NEXT TWO MINUTES THE CONTROLLER SAW TWO ADDITIONAL SUMP INDICATIONS THAT GAVE HIM CONFIRMATION WE HAD A PROBLEM. THE CONTROLLER IMMEDIATELY TRIED CONTACTING THE FIELD PIPELINER TO SEE IF THERE WAS ACTIVITY (PROVING) AT THE STATION AND THEY HAD JUST FORGOTTEN TO CALL THE CONTROL CENTER. AT THAT POINT 15:42, THE CONTROLLER SENT A STOP TO THE PUMP AND INITIATED BLOCK IN AND TANK CLOSURE, THE CONTROLLER MADE CONTACT TO THE FIELD WITH PHONE. SECONDARY PIPELINER, HAD A BRIEF CONVERSATION ABOUT WHAT HE SAW AND THAT THE SYSTEM WAS SHUT DOWN. THE PIPELINER RESPONDED TO THE SITE. THE CONTROLLER HAD THE PUMP'S DOWN AND THE TANK BLOCKED IN. THE CONTROLLER SUBSEQUENTLY INITIATED SHUT DOWN AT TEPETATE AND DISABLED THE PERMISSIVE PUMP AT GILLIS TRYING TO ISOLATE THE LA01 SEGMENT. AFTER SOME DISCUSSION WITH THE CONSOLE SUPERVISOR AND LEAD CONTROLLER, THE CONTROLLER INITIATED CLOSURE OF MOV 01 AT TEPETATE JUST TO ENSURE TOTAL ISOLATION ON THE SEGMENT.
