Narrative
On 10/24/2017 the control center notified field personnel that thomas station shut down at 11:25 due to an lel alarm. Field personnel were dispatched and arrived on site at 11:45 and discovered oil on the ground and notified the control center to fully shut down the pipeline system. Approximately 20 barrels were released with 3 barrels entering an unnamed pond adjacent to the station property. Trrc was notified on 10/24/2017 at 12:24 and incident #1649 assigned. The water impact was not discovered until approximately 15:10 and nrc notification was made at 15:51 cst on 10/24/2017 and report #1194198 issued. All free product was recovered via vacuum truck from station property and pond and contaminated soil was excavated for onsite remediation. Further investigation & excavation revealed a pinhole in the piping at the 6 o'clock position and a plidco clamp was installed. The station was returned to service on 10/25/2017. Nrc 48 hour update was made on 10/26/2017 at 13:27 and report #1194375 issued. The failed section of piping saw infrequent flow due to operational setup of the station and at the time of the failure was isolated from the mainline operation. Subsequent to the temporary repair the failed section of pipe was cut out and examined in the field. Internal corrosion was determined to be the cause of the failure. To prevent future recurrence the entire section of piping has been removed and the design has been reconfigured to eliminate the section that saw infrequent flow and remaining necessary piping has been moved above ground.
