Incident Narrative

AT 7:40 AM 6/4/12 COMPANY INSPECTOR WAS AT STATION FOR ONGOING CONSTRUCTION PROJECTS AND FOUND OIL LEAKING FROM THE BOTTOM OF A 16' 150# ANSI FLANGE ON A SPOOL IN THE STATION SUCTION MANIFOLD. HE IMMEDIATELY CALLED THE CONTROL CENTER AND ADVISED THEM OF THE SPILL AND TOLD THEM NOT TO START ANYTHING AT THE STATION (AS IT WAS DOWN). HE THEN INITIATED EMERGENCY RESPONSE TO NOTIFY ADDITIONAL COMPANY PERSONNEL AND GET THEM EN-ROUTE. HE ALSO CALLED VACUUM TRUCK CONTRACTOR. HE THEN BEGAN ISOLATION OF THE AFFECTED FLANGE BY CLOSING THE NEAREST VALVES TO THE SUCTION MANIFOLD. HE CLOSED VALVE V1446 BOOSTER PUMP DISCHARGE VALVE AND FOUND ALL OTHER VALVES CONNECTED TO MANIFOLD ALREADY CLOSED, INCLUDING THE INLET VALVES OF THE STATION DISCHARGE METERS. VACUUM TRUCK WAS USED TO EMPTY MANIFOLD CONNECTED TO AFFECTED FLANGE. AS ADDITIONAL COMPANY PERSONNEL ARRIVED ALL FREE OIL WAS PICKED UP FROM SURFACE AND REMAINING RESIDUE WAS COVERED WITH SPHAG SORB TO ABSORB REMAINING OIL. IMPACTED SOILS WERE PICKED UP AND MOVED TO REMEDIATION SITE. THERE WAS LITTLE IMPACT BELOW SURFACE AS GROUND WAS VERY WET FROM RECENT RAINS. SPOOL WAS REMOVED AND CREW FOUND THAT GARLOCK GASKET MATERIAL HAD FAILED AT THE BOTTOM OF THE FLANGE. A NEW 16' 150# VALVE WAS INSTALLED IN PLACE OF SPOOL AND NEW GASKETS WERE INSTALLED. PRELIMINARY INVESTIGATION POINTS TO OVERPRESSURE DUE TO THERMAL EXPANSION. CONTROL ROOM OPERATIONS DATA CONFIRMS THAT EL DORADO STATION HAD BEEN SHUT DOWN ON 6/3/12 AT 11:02 AM FOR A SCHEDULED SHUT DOWN. CONTROLLER ON DUTY FOLLOWED THE PROPER PROCEDURE FOR THE SHUTDOWN, INITIATING THE PROPER COMMANDS TO THE PROPER EQUIPMENT UNTIL THE TANK VALVE MOV 1419 (THAT THE PROCEDURE CALLS FOR TO BE CLOSED) DID NOT RESPOND. CONTROLLER SENT TWO OTHER COMMANDS TO SAME VALVE BUT IT DID NOT RESPOND. AT THIS POINT THE CONTROLLER DECIDED TO CLOSE THE METER INLET VALVE (MOV 1449) INSTEAD. HE DID NOT INITIATE AN AOC NOR DID HE CALL ANYONE OUT TO INVESTIGATE. BY DOING THIS HE ISOLATED THE SUCTION MANIFOLD AND ASSOCIATED PIPING FROM THE PRESSURE RELIEF SAFETIES. ADDITIONAL THERMAL RELIEFS WERE INSTALLED ON METER INLET VALVES BEFORE STATION WAS RESTARTED.
