Narrative
Approximately 165 barrels of crude oil were released from the pump 9 discharge station piping at china grove station. The date and time of the release (part a q4) is indicative of the earliest possible time the release could have started, as it was the date/time that the pump had started. The cause of the release was attributed to external corrosion as a result of stay current inference. To prevent future incidents, an interrupted close interval cathodic protection survey will be performed to determine the cause of the stray current and ensure that other facility piping does not have stray current interference. Supplemental narrative: updated the nominal diameter of the failed section of pipe to 10" (part c q3.A). Supplemental narrative (2): the cause of the release was attributed to external corrosion, likely from stay current inference as indicated by the pit morphology. The type of stray current interference is not known (part g1 q2a). To prevent future incidents, a cis survey was conducted and results indicated that the incident location met criteria. Additionally, in 2022, non-destructive testing inspections will be conducted for select pipeline segments within the facility.
