Narrative
On 7/31/17 at approximately 11:21am the pipeline control center noted a decrease in pressure and associated alarms on the 10" goodrich to douglass segment of the kilgore to oti pipeline. The pipeline was immediately shutdown and field personnel notified to investigate. At approximately 11:41am the control center received a call from 2nd party contractor that was performing row mowing indicating that one of the mowers had struck the line in a shallow/exposed area and there was a release of crude oil. At approximately 12:30pm operator personnel arrived on site and determined that there was a release of crude oil and that the cost of cleanup and repairs would likely exceed $50k. Nrc was notified at 13:26 and the release was assigned report no. 1185799. A plidco mechanical clamp was installed over the failure. Follow up 48hr nrc report was filed on 8/2/17 at 13:06 and assigned report no. 1186040. Once temporary repairs were completed a static pressure test was accomplished prior to restart on 8/3/17. All free product was recovered and impacted soil was remediated on-site. Permanent repair has been accomplished via cut out and replacement and line was provided 36" of cover to aid in prevention of future recurrence.
