Narrative
At approximately 6:00 am on june 20, 2011, the station operator conducting a drive through inspection of the hendrick tank farm observed a large stain at the surface of the 24" suction fill line of tank 323. The control room was immediately notified and the pipeline was shutdown by 6:02 am. Surface soils were removed, and a localized corrosion hole approximately .750" in diameter was found at the low lying point of the pipeline segment. A temporary clamp was applied and the pipeline was put back in service at 9:00 am. The failed section of the pipe was cut out and replaced and sent to a third party lab to identify the cause of the metal loss. Test results determined the failure was due to acid producing bacteria (apb) corrosion at the 6 o'clock position which is due to bacteria usually being found in water; water would accumulate at this point of the pipeline. To minimize the possibility of recurrence, the line was replaced with a new line. The old line was 0.330"w.T and the replacement line is 0.375"w.T. Biocide treatments will also be increased from once a quarter to a monthly basis. This failure released 275 barrels of crude oil. The amount released was calculated using a spill calculation sheet which measures the width and depth of the saturated soil and amount collected by vacuum truck.
