Cushing east facility was making a delivery of crude oil on the 16-inch c66 pipeline to magellan when a leak was discovered near the north manifold. The line was immediately shutdown and notifications were made. There were no injuries and no water was impacted as a result of this leak. It is estimated that 75 bbls of oil was released. The leak was not on the c66 pipeline. It was in the north manifold area on a dead leg of piping. After excavting the line, the leak appears to be internal corrosion on an elbow in the line. The pipe was shipped 10/11/2012 to a lab in houston for metallurgical testing. Attached is the failure analysis report. The leak occurred on a dead leg as indcated in the attached site drawing. Attached are photo's of the leak site, incident investigation report, deadleg action plan, site drawing, and failure analysis report from stress engineering. The dead leg action plan has assessed 18 dead legs to be removed or drained. There are 10 dead legs ranked as high risk - 8 of these has been completed. The remaining items on the plan will continue to be drained or removed from service.
