Narrative
On friday, april 12, 2013, during a routine aerial patrol, a pilot, contracted by nustar logistics, l.P. (nustar) discovered staining on the right-of-way of nustar's 12-inch gardendale intrastate pipeline system (tx t4 permit 08433). Nustar personnel were immediately dispatched, and the pipeline segment was shutdown. The accident occurred in a rural, non-hca location in la salle county, tx. Approximately twenty-five barrels of crude oil was released, and approximately nine barrels were immediately recovered. The cause of the leak appears to be internal corrosion of the pipe's surface. The affected pipe segment was removed and replaced on friday, april 19, 2013. Update - the removed segment of pipe was examined by a third-party laboratory. The examination concluded that the leak occurred at a through-wall internal corrosion pit that formed by microbially induced corrosion (mic).
