Narrative
On august 5, 2013, operations personnel from another pipeline company discovered liquid product in a valve vault situated near the northeast corner of the kinder morgan (km) terminal located at 2000 east sepulveda boulevard in carson, ca. Km began investigating the release the source of the release. After further investigation, km determined the release was from tesoro logistics operations llc's line t07, and on august 14, 2013, notified tesoro logistics operations llc (tesoro logistics) of a leak on line t07. On august 15th, tesoro logistics isolated the leak by installation of a clamp and provided updated notifications to agencies. Line t07 was repaired and returned to service on august 19, 2013. A metallurgical analysis determined that the segment of pipe that failed leaked at a region of wall loss from external pitting corrosion. Based on the location (8:30 o'clock position) and morphology, tesoro logistics concluded the corrosion initiated at an area of disbonded coating that was likely caused by external mechanical damage, such as excavation equipment hitting the line. Periods of sub-criteria cathodic protection (cp) levels and the presence of corrosive soil were also determined to be contributing factors to the failure. Approximately 130 barrels of jet fuel were recovered. The release did not impact the surface water of the dominguez channel. Cost estimates include a multi-year remediation effort.
