Incident Narrative

ON FEBRUARY 19, 2021 AT APPROXIMATELY 9:30 AM CST, A TECHNICIAN CONFIRMED A RELEASE OF CRUDE OIL NEAR MAINLINE VALVE 12-55-V-1 ON LINE 55 IN THE FLANAGAN TERMINAL. THE EDMONTON CONTROL CENTER WAS NOTIFIED, AND LINE 55 WAS IMMEDIATELY SHUT DOWN. UPON INVESTIGATION IT WAS DETERMINED THAT APPROXIMATELY 23.5 GALLONS HAD LEAKED OUT FROM THE BODY BLEED CONNECTION TO THE VALVE AND DID NOT MEET NRC REPORTING CRITERIA. THE CAVITY DRAIN VALVE WAS REPLACED AND THE LINE WAS RETURNED TO SERVICE LATER THAT DAY. ON FEBRUARY 23, 2021 AN ASSESSMENT OF THE STATUS OF CLEAN-UP WAS MADE AND IT WAS DETERMINED THE RELEASE AMOUNT WAS APPROXIMATELY 40 GALLONS OF CRUDE OIL AND WOULD REQUIRE NRC NOTIFICATION. INITIAL NRC NOTIFICATION WAS MADE ON FEBRUARY 23, 2021 AT 6:07 PM CST (NRC #1298834). A 48-HOUR UPDATE WAS MADE TO THE NRC ON FEBRUARY 25, 2021 AT 3:35 PM CST (NRC# 1299005). THE ORIGINAL RELEASE AMOUNT WAS LARGELY IDENTIFIED BY PRODUCT STAINING OF SURFACE WITH ONLY SMALL POCKETS OF FREE OIL. FROZEN GROUNDS DELAYED THE DISCOVERY OF THE ADDITIONAL PRODUCT DUE TO OIL THAT TRAVELLED ABOVE A CLAY LAYER AND BELOW THE FROST WHICH IS 12"" TO 16"" DEEP WHICH EXPANDED THE IMPACT AREA AND COST ASSOCIATED WITH THE RELEASE. ALL CONTAMINATED SOIL HAS BEEN CLEANED UP AND PROPERLY DISPOSED OF. THE CAUSE OF THE RELEASE WAS DETERMINED TO BE DUE TO TEMPERATURE CHANGES FROM FREEZE TO THAW OF THE GROUND CAUSING MOVEMENT OF THE BURIED PIPE NIPPLE.
