Narrative
Magellan's northern district office was notified of a reported sheen on water in a drainage ditch by the minnesota pollution control agency. The northern district office informed magellan's operations control center whereupon the line was immediately shut down. Up-and-down stream valves were closed and a ground search was conducted which included excavating the line in the vicinity of the reported sighting. A large rock was discovered immediately under the pipeline. When the rock was removed a leak was discovered on the bottom of the pipe which had been resting on the rock. Metallurgical analysis determined the cause of the release as a through the wall crack in a bottom side deformation anomaly that grew from mechanical damage on the inside surface of the pipe.
