Narrative
On january 6, 2010 at approximately 19:30 local time, enbridge operations at the superior terminal observed a small show of oil near the line 4 manifold relief valve area while performing routine rounds. Superior pipeline maintenance immediately responded and a vacuum truck and absorbent pads were used to collect the free product (approximately 20 gallons). A ground thaw unit was set up to facilitate excavation to investigate the leak source. The source of the leak was found to be a cracked auxiliary pipe on a crossover valve located within the terminal. The auxiliary piping associated with the crossover valve was repaired. The cause of the leak was determined to be 'natural force' damage caused by cold temperatures and subsequent frost heave in the area.
