Narrative
Local emergency responder notified control center via telephone on 3/17/2014 at 22:40 of petroleum odor in the area. Local operating personnel were contacted by the control center at 22:49, were dispatched to location to investigate the odor complaint and arrived onsite at 00:45 on 3/18/2014. After a search of the area the release of crude oil from the hebron to lima segment was confirmed at 01:02 on 3/18/2014 by local operating personnel at mp 807. Just prior to the call into the control center from the local emergency responder, a delivery upstream of the hebron to lima segment had begun at approximately 22:34 on 3/17/2014. Therefore, the 20" hebron to lima segment was not running and was under static pressure at time of release confirmation. After receiving the call and learning of the approximate location of the odor complaint the control center took the precautionary measure of closing the upstream and downstream motor operated valves to isolate a sub segment of the hebron to lima segment between mp 802 and 808. Valves were confirmed closed at approximately 23:29 on 3/17/2014. Upon excavation of the failed section of pipe a crack of undetermined cause (at the time was found). A plidco clamp was installed over the failed section of pipe. Integrity pressure test was successfully completed on 3/23/14 and the line segment was restarted later that day at 16:53 under a 20% pressure reduction in operating pressure. On 4/15/2014 the failed section of pipe was cut out and replaced. Subsequent to the permanent repair the line was restarted and continues to operate under a PHMSA instituted 20% reduction in operating pressure. The results of the metallurgical analysis indicates that the pipe section leaked at a colony of axially oriented, interlinked near-neutral-ph stress corrosion cracks that were located at a dent. A total of 756.89 yards of contaminated soil was removed from the site. All times noted above are et.
