Narrative
On 11/27/2023 at 15:46, facility contractors working nearby noticed crude in the containment dike of tank 2660. The leak was coming from the suction/fill line inside the tank dike. Approximately, 120 barrels of crude oil was released into the containment dike. Clean-up crews were dispatched and removed free product and contaminated soil. The failed pipe was temporarily repaired with a clamp. Accident cause has yet to be determined. A supplemental report will be submitted once the pipe is removed and analyzed. Supplemental report: tank 2660 was isolated, drained, cleaned and degassed in 2022 for internal 653 inspection and was not returned to service subsequent to the inspection. The dedicated suction/fill line for this tank became a dead leg after the tank was removed from service from the tank shell valve to the booster pump. Subsequent to the initial mechanical clamp application to control the release the failed section of the suction fill line was fully removed from the ground and the internal surface examined. The visual examination determined the cause was internal corrosion. The remaining section of associated piping is above ground, capped, drained and isolated from the system. The remaining section will be removed in the near future. Dead leg management program is in place for the facility and as tanks move to out of service status and are scheduled to remain in that status associated piping will be removed to prevent future, similar type failures.
