Narrative
Magellan personnel discovered an area of pooled crude oil on the surface above magellan's north el dorado to to cushing 8-inch crude oil pipelineat a location inside magellan's boyer tank farm/pump station. The investigation at the site revealed two separate points of crude oil release on the pipe body. The defective pipe was subsequentially replaced with a new segment of pipe. The portion of the line that is inside the boyer facility was hydrostatically tested and returned to service. Metallurgical analysis of the segments of pipe where the anomalies were found determined the root cause of the release was from external corrosion. The impacted soil was removed and replaced with clean soil. The impacted soil was remediated in accordance with company and state guidelines.
