Narrative
On tuesday, september 3, 2013, nustar's control room in san antonio, tx received a low-suction alarm on nustar's 8-inch 53p three rivers to san antonio (south) pipeline system. The three rivers pump station was automatically shut down on the alarm, and the pump station discharge valve was closed. Throughout the evening of september 3rd and early morning of september 4th, nustar personnel drove the entire pipeline segment from three rivers, tx to nustar's san antonio south terminal checking immediate response areas. On wednesday, september 4, 2013, nustar personnel discovered a release on the row of the pipeline approximately 0.5 miles north of hwy 72 near three rivers, tx. The accident occurred in a rural, non-hca location in live oak county, tx. Approximately 2,752 barrels of gasoline was released, and approximately 817 barrels have been recovered to-date. The affected pipe segment was removed and replaced on thursday, september 5, 2013. The affected pipe segment was sent to a third party metallurgical laboratory for analysis. The rupture was caused by external corrosion underneath tape coating applied over the girth weld region. The corrosion was isolated to the pipe beneath the tape coating. The corrosion progressed to a depth where the remaining wall thickness was unable to contain the internal pressure.
