Narrative
At approximately 11:30 a.M. On june 18, the landowner reported seeing dead vegetation accompanied by an ammonia odor to magellan personnel. Magellan treated the notice as an investigation event and promptly shut down the line. The line was excavated, and the release was found consisting of a pinhole release in the long seam of the pipe. A temporary repair was made by installing a plidco clamp. The pipe segment was cut out and sent to a laboratory for metallurgical analysis, and new, pre-tested pipe installed in its place. Metallurgical analysis determined the leak was due to a penetrator type through-wall lack of fusion defects in the erw seam. Approximately 400 cubic yards of impacted soil was remediated. This revised supplemental-final report was filed at the request of the central region to correct errors in the previous report bearing the revision date of 3-31-2015.
