Narrative
Approximately seven barrels of crude oil were released within facility boundaries from the 12 inch suction line of pump 5 at dominguez hills station. The date and time of the release (06/30/2020 at 14:55) is indicative of the earliest possible time the release could have started, as it was the last time the station had been inspected and confirmed no oil was being released. A supplemental report will be submitted pending further investigation into the cause of the incident. Supplemental narrative: after the third party failure analysis was completed, it was determined that microbiologically-influenced corrosion (mic) is suspected of initiating or assisting the pitting attack based on the morphology of the pitting and the presence of acid-producing bacteria (apb), iron-oxidizing bacteria (iob), and denitrifying bacteria (dnb) found in the corrosion products. The confinement of the pitting between the 11:00 and 1:00 position is likely due to the lower flow velocity at this position compared to other clock positions in the elbow. A section of the vertical pipe upstream, the elbow, and the horizontal section of the pipe downstream were replaced to prevent re-occurrence. Supplemental narrative (2): wall thickness was updated (part c, q3.B) according to the range (.380 - .405 inches) provided by the third party analysis.
