Narrative
On october 12, 2017 contract crews were on-site to perform excavation of an anomaly that was discovered during an ili tool run. While beginning excavation, the crew encountered contaminated soil and identified a pinhole leak. A repair clamp was immediately installed to stop the release and repair the anomaly. The contaminated soil was cleaned-up and disposed of. The cause of the external corrosion is due to wax coating inadequacies, the cp environment and tool technology capabilities.
