Narrative
On july 16, 2019, at approximately 10:40 hrs pst, while conducting routine cp survey inspections at 228th and nicolle street, torrance basin pipeline employees identified a hydrocarbon odor to which they investigated by checking surrounding areas and subsequently identified a crude oil release in the vault. Immediately, the employee uplined internal notifications to management and the pipeline control center to shut down the pipeline. In addition, the upstream and downstream valves were isolated further securing this segment of the pipeline. Spill calculation estimates based on the footprint of the vault are approximately 7.8 barrels of crude oil. All crude oil product was promptly recovered via vacuum truck and reinjected into the system at torrance meter station. Appropriate external notifications were made; at 11:40 hrs pst, cal oes was notified, control number 19-4536. At 11:54 hrs pst, cupa los angeles county was also notified. On july 26, 2019 tbp notified nrc due to potentially reaching $50,000 for repair and/or soil removal and disposal expenses, nrc report #1253299. On july 28, 2019, a 48-hr notification was made with no changes, nrc report #1253431. The source of the release was from a pinhole located on a deadleg lateral 4 inch pipeline. This 4 inch lateral connected to an active 10 inch mainline m-131. The pinhole was at the 4:00 o'clock position of the pipe upstream of the flange. Initially, a pressure containing clamp was placed over pinhole to stop the release. The final repair was removing the deadleg which took place on july 31, 2019. The cause of the pinhole is believed to be internal localized corrosion. Samples of the fluid and sediment have been collected and sent to the lab for testing. The results of these tests will be reported in a supplemental report to this 7000.1 report. __________________________________________________________________________________________________________________________ this narrative includes a correction to original narrative: ...Pinhole located on a 25' deadleg lateral 4 inch pipeline, g-29. Supplemental report updates: part g1 corrosion failure, question #7 - type of corrosion (changed from other/yes/undetermined until liquid and sediment lab results are received) to (corrosive commodity, water drop-out/acid, and microbiological) part h narrative description of accident- torrance basin pipeline (tbp) has received lab results from enhanceco for the fluid and sediment samples taken at the through-wall area. The evidence produced from the lab, for the sample taken at the pin hole, indicates the following characteristics; microbiological (presence of mic associated bacteria), water drop-out/acid (low ph-acidic) and corrosive commodity (low ph-acidic). The corrosion appears to have started from the crude sitting in an existing corrosion cell between the 3:00 and 9:00 positions for an extended period of time. The absence of flow, cleaning pigs, and chemical inhibition on this deadleg lateral line may have contributed to the continuation of corrosion until the through-wall penetration occurred. Shortly after the release, this deadleg was removed; however, additional actions to be taken by tbp include: ensuring the mainline is inhibited per design; ensuring the line does not shut down for excessive periods; running a cleaning pig program, and removing any other unnecessary deadlegs. This concludes the findings and investigation for this incident.
