Narrative
On july 18, 2014, at 2200 hours, the centurion pipeline (cpl) control center (ccc) initiated a startup of a customer lact unit and observed a failure to build pressure on the awc to seminole 8 inch line. A tech was dispatched and the lact was restarted to confirm normal operation. The lact was operating normally, so it was shut down until integrity of the line could be confirmed in the morning. Functional checks of the equipment at seminole began at 0730 hours on 07/19/14. At 0850 hours , mike warren, west region manager, contacted the centurion aerial patrol contractor to request a fly over the suspected leak of the pipeline. At 14:28, the pilot reports that he spotted a leak at mp 49.5. Cpl techs were contacted to respond to the site and to close the upstream mainline valve at mp 43. Ccc shut down and inhibited the customer lact at 1428 hours. At 1458 hours, vacuum trucks were called to the site. At 1515 hours ccc opens seminole station back pressure valve to allow for drain-in to that station ( approximate 300 feet elevation drop to station). At 1658 hours, the land owner ( xto) was notified of the leak. At 1740 hours, becky moore notified texas railroad commission by phone to report leak. At 1650 hours, cutty cunningham notified nrc of leak by phone. Techs at the site observed that oil was being pulled back into the valve body by gravity feed to the station. At 2049 hours, approximately 145-150 bbls were recovered by vacuum truck. At 2050 hours, oil pickup was completed. The plidko temporary clamp used has maintained stable operation. Centurion delayed a final repair pending a smart pig run to determine if portions of the pipe might need to be replaced. Once that decision and repair is completed, centurion will file its final report. A final report was received from the internal inspection, a rehabilitation plan was published and several cutouts were accomplished, including pipe in the location of the release.
