Narrative
The station operator observed oil in the dike of tanks 21 and 22 during daily location inspection. The lines were isolated and free standing oil was removed prior to excavation. Line was hydro excavated and the leak was clamped the following morning. 1500 feet of 24 inch pipe from manifold a to tank #23 was removed and replaced. Line was put back into service on june 22, 2012. The removed pipe was sent to lab for metallurgical analysis. Metallurgical report on the pipe indicated internal corrosion was the reason for the leak. Additional corrosion inhibitor has been added to the injection point for this area to assist in mitigating the internal corrosion. Remediation was completed on the remaining contamination.
