Narrative
A third party notified magellan personnel of seeing a dead spot on the ground above the line. Magellan personnel investigated and discovered a pinhole in the line wich was subsequently repaired by the installation of a full encirclement sleeve, and the line restored to operation. The pipe segment containing the defect was later replaced with new, pretested pipe and the defective specimen sent to a laboratory for metallurgical analysis which concluded the leak was due to a penetrator type through-wall lack of fusion defect in the erw seam. Approximately 800 cubic yards of impacted soil was remediated.
