Narrative
Approximately 7.3 barrels of crude oil were released from the 16" tank line for t1654 at nettleton station. The date and time of the release (part a q4) are indicative of the earliest possible time the release could have started based on the last date/time the release location was visited and confirmed to be no release of crude oil. The cause of the release is attributed to internal corrosion; the corrosion mechanism is under investigation. A supplemental report will be submitted pending further investigation into the corrosion mechanism and preventative measure. Supplemental: the cause of the internal corrosion is attributed to microbiologically induced corrosion (mic) and under-deposit corrosion. To prevent future incidents, the failed segment will be replaced, and the facility flow will be reviewed to determine further mitigative actions such as reducing the diameter of the pipe or introducing chemicals to the station piping.
