Narrative
On june 20, 2019, at approximately 0813 hrs pst, upon arrival to belridge station for work on the plains belridge meters, gauger discovered a crude oil release coming from pump #5. The source of the release was visible from the nipple of the relief valve. The gauger responded immediately by shutting down and isolating pump #5 from the system. Spill calculation estimates based on the footprint of the spill are 21 barrels of crude oil to concrete containment pad and zero outside of secondary containment. Internal and external notifications were made. At 0840 hrs pst, cal oes was notified, control number 19-39666. At 0847 hrs pst, cupa kern county was also notified. All crude oil product was promptly recovered via vacuum truck and reinjected into the system at continental station. Failed fitting has been sent to the lab for failure analysis; the results will be reported in a supplemental report to this 7000.1 report. _________________________________________________________________________________________________________________________ this narrative includes a correction to original narrative: control number 19-3966. Supplemental/final report updates: part g6 - equipment failure, question 6 - equipment failure sub-cause: other: changed from "under investigation" to "see narrative" part h narrative description of the accident- the metallurgical report supports the conclusion that the failure of the relief valve was caused by fatigue cracking in the area of the threaded outlet nipple associated with the relief valve. The report further indicates that specific location of the fatigue cracking was coincident with a change in section thickness as well as corrosion, factors that both result in a localized stress concentration. The metallurgical analysis concluded that there was no obvious indications of variations in microstructure (I.E. Manufacturing defects) that would account for the failure. Upon evaluating the operation of belridge station, a determination has been made to eliminate the threaded coupling which is susceptible to fatigue and install new relief valves with welded flanges. The failed relief valve has been replaced along with six other relief valves at this pump station with welded fittings. This concludes the findings and investigation for this incident.
