Narrative
Magellan operations control center received a call from an inspector working for another pipeline company stating that magellan had a leak on what appeared to be a 6-inch pipeline located on the kansas city/fairfax northbound bridge. No pressure drop was detected by magellan pipeline control scada (supervisory control and data acquisition) located in tulsa, ok. The kci 6-inch line was inactive at the time of the call. As a precuation, operations control initiated the shutdown of all incoming and outgoing pipeline operations at the magellan kansas city facility. Field personnel were sent to the bridge to investigate. A subsequent investigation discovered a small drip coming from the line. The final amount determined to be released was 1 gallon. There was no confirmed trace of released product identified in the missouri river waters, as any product that reached the river would have quickly been dissipated. The national response center was called at 13:47 to report the initial release with an estimated worst case potential release of 250 bbls. A second call to the nrc was made at 16:13 to inform them the released quantity had been revised downward to an estimated 1 bbl. It was later determined that the actual quantity released was one (1) gallon, which is the amount reflected in this report. The line segment containing the feature was removed and sent to a laboratory for metallurgical analysis, and a piece of new, pre-tested pipe was installed. The metallurgical analysis determined that the leak occurred due to external corrosion between the pipeline and the bridge support which consisted of a partial encirclement bracket fillet welded to the pipe. This area was exposed to the atmosphere and crevice corrosion occurred along with atmospheric corrosion.
