Narrative
On may 17, 2017 at approximately 17:47 cdt, an estimated 125 barrels of crude oil was released from the temporary trap that was installed to run a smart tool on tank line 1049 in the cushing north terminal. The released product remained on enbridge property and was recovered from secondary containment in the tank dike area. This release occurred while enbridge and contractor personnel were preparing to perform an inline inspection of tank line 1049. Tank 1049 had been isolated from tank line 1049 and a temporary trap and valve had been installed on the tank line in order to accommodate this tool inspection. Once the tool was loaded into the trap, the crew noticed oil coming from the trap prior to the trap door being closed. The crew was not able to fully close the trap door while the product was being released. The cushing control center was contacted at 17:49 cdt to isolate the trap. All crude oil was contained on-site within the tank berm area and clean-up was completed on may 18, 2017. Remediation consisted of removal and replacement of the temporary valve. The tank line and tank were placed back in service on may 19, 2017. Appropriate notifications were made with the original call to the nrc at 19:08 cdt (ncr #1178607) and the 48-hour follow-up on may 19, 2017 at 08:43 cdt (nrc# 1178745). In addition, the oklahoma corporation commission (occ) was notified on may 18, 2017 at 10:08 cdt (#18517ogdo10239).
