Narrative
On july 22, 2015 at approximately 1:25 pm, a gauger discovered approximately 14 barrels of oil on the ground near the line 6a ultrasonic flow meter at the superior terminal. The gauger contacted the edmonton control center and line 6a was shutdown. The superior plm was dispatched to begin clean up and excavate to determine the leak source. It was discovered that the small diameter piping on the line 6 valve 6-ov-6c, which is on the suction side of the line 6 station, had failed. The two seat packing pipes had broken off at the point where they entered into the valve body. All six piping assemblies were schedule 80 and have been replaced with schedule 160. The fittings (elbow) have also been upgraded from a 2000 # rating to a 3000 # rating. Further investigation revealed that the release was due to frost heaving the small diameter piping assemblies. Approximately 380 cubic yards of contaminated soil have been hauled away to an approved landfill.
