Incident Narrative

"ON JANUARY 19, 2026, AT 12:45 MST, THE CONTROL CENTER ATTEMPTED TO SHUTDOWN AND ISOLATE LINE 40 IN RESPONSE TO AN UNRELATED ALARM AT FAULKNERS COULEE STATION (UPSTREAM OF EAGLE BUTTES STATION). DURING ISOLATION, THE EAGLE BUTTES SUCTION VALVE (SP0352 13 40 V 1 / MLV 23A) FAILED TO CLOSE, AND A TECHNICIAN WAS SENT TO EAGLE BUTTES STATION. AT 14:51 MST, THE TECHNICIAN ARRIVED AT EAGLE BUTTES STATION AND DISCOVERED CRUDE OIL ON THE GROUND NEAR THE VALVE. THE CONTROL CENTER WAS NOTIFIED AND PROCEEDED TO ISOLATE THE AREA BY CLOSING ADDITIONAL UPSTREAM AND DOWNSTREAM VALVES. THE SOURCE OF THE RELEASE WAS FOUND TO BE A LEAKING VALVE STEM SEAL, WITH AN INITIAL ESTIMATE OF APPROXIMATELY 25 GALLONS OF CRUDE OIL BEING RELEASED. REGION MANAGEMENT WAS NOTIFIED AND THE NRC WAS CONTACTED AT 16:21 MST (REPORT #1453058), BASED ON INITIAL CLEANUP COST ESTIMATES EXCEEDING REPORTING THRESHOLDS. TECHNICIANS WERE MOBILIZED TO THE SITE TO BEGIN INITIAL CLEANUP, AND CONTRACTORS WERE MOBILIZED THAT EVENING. A HYDROVAC TRUCK ARRIVED ON JANUARY 20, 2026, AT 03:00 MST AND RECOVERED THE REMAINING RELEASED PRODUCT, COMPLETING CLEANUP ACTIVITIES. THE 48-HOUR NRC UPDATE WAS MADE ON JANUARY 21 AT 14:53 MST (REPORT #1453153), REVISING THE RELEASE VOLUME TO 3 BARRELS. THE INVESTIGATION DETERMINED THE CAUSE TO BE NORMAL WEAR OF THE VALVE STEM SEAL FROM YEARS OF SERVICE. THE VALVE STEM WAS REPACKED AND RETURNED TO SERVICE."
