Narrative
On may 18, 2021, at approximately 1016 hrs. Pdt, a torrance pipeline company (tpc) operator conducting facility rounds arrived at eptc meter station. Upon arrival, the operator discovered crude oil product on the ground inside the facility. The operator immediately contacted his supervisor; tpc supervisor arrived on site at approximately 1033 hrs. Pdt. Cleanup and recovery crew were dispatched to the facility to commence response efforts. Initial estimates approximately 1 barrel of crude oil to soil. Internal and external notifications were promptly made. On may 18, 2021, at 1042 hrs. Pdt, cal oes was notified - control number #21-2652. At approximately 1052 hrs. Pdt, nrc was notified - report #1305340. On may 20, 2021, a 48-hour report to nrc was made - report #1305563; no changes to report at that time. The source of the release, a two-inch thermal relief line with a through wall pinhole at the 6 oclock position was located and secured as ongoing cleanup was performed. The thermal relief line was replaced and permanently repaired. An investigation is underway to determine the cause of the release; a supplemental report will be submitted. ________________________________________________________________________________________________________________________ supplemental / final report updates: updated part d, items 8a-8g updated part g1, ic, items 6-13 updated part h, narrative description of the accident: torrance pipeline company has concluded its investigation and has identified the cause of the release. As initially reported at the 6 oclock position, a through wall pinhole was identified. Based on visual field examination and non-destructive flexoform phased array and conventional ultrasonic evaluation, it has been confirmed to be an isolated internal corrosion pit. Initial mitigative action was to replace the failed two-inch thermal relief line with a new two-inch thermal relief line. Additional mitigative actions include implementation of weekly operator/line rider facility visits and inspections inside all remote meter station sites. Future potential implementations include development of a facility integrity inspection standard in addition to evaluating remote meter/pump stations and prioritizing future facility integrity inspections of deadleg, no flow or low flow piping. This concludes the investigation and actions taken for this incident.
