Narrative
Call was received by control center at 20:38 on 6/7/2015 from a landowner noting a petroleum type odor in a field several miles upstream from wortham. Control center shutdown pipeline at 20:42. Pipeliner was dispatched to the site and confirmed that there was a small volume of crude oil released at mp 264. The area was excavated and after removing the coating from the pipe a pinhole type pit was observed in the center of a larger diameter corrosion pit. The volume out was estimated at one barrel. Because of soil saturation levels in the area due to recent heavy rainfall all of the oil surfaced and there was very little soil contamination. A plidco clamp was installed and the line was restarted on 6/9/2015 at 08:12 under a 20% reduction in operating pressure that was previously established due to PHMSA mandate. The plidco clamp has since been removed and a new section of piping has been installed. The system continues to operate under the 20% reduction in operating pressure.
