Narrative
On 6/28/18, magellan's contractor was excavating for a targeted ili rehabilitation dig location at mp 170.2 on the midland to corsicana 16". Upon excavating, the rehab crew encountered product contaminated soil. Work was stopped and magellan personnel were notified. The pipeline was shut down and isolated. Affected soil at the release site was excavated and properly disposed. Fresh soil was brought in to replace the removed impacted soil. A pinhole leak was found to be at the 12:00 position on the pipe where a cathodic protection test lead had been cadwelded to the pipeline by a previous pipeline operator and left uncoated. Localized external corrosion occurred in the uncoated area of the pipe to the extent that a small corrosion pinhole developed. Coating surrounding the external metal loss was removed and a fully welded type b steel reinforcement sleeve was installed to repair the leak. Approximately 10 cubic yards of soil were remediated.
