Narrative
On july 15, 2017 at approximately 10:15 cdt, an operation technician called the cushing control center (ccc) to report heavy crude oil on the basin pond located southwest of manifold 227 in the cushing south terminal. The ccc notified the on-call personnel manager who started the incident communication process. Enbridge on-site personnel estimated the release to be approximately 451 barrels of heavy crude oil located in the pond and corresponding ground area. While the #3 header between manifold 227 and 229 was not in operational use and was isolated, a loto of additional hand valves was completed to further isolate the suspected leak location in order to begin the recovery process and safely determine the exact release location. It was determined that the release point occurred on a below grade 20" transfer line (pressurized dead leg segment) running between manifolds 227 and 229. The release point was noted to be in the 6:00 position. The cause of the release is internal corrosion. Nde and product testing was conducted to verify the leak cause. The dead leg piping was permanently removed from service in september 2017. All crude oil was contained on enbridge property within the basin pond containment area (southwest of tank #3332) and clean-up was completed on july 22, 2017. Approximately 371 barrels of product was recovered and returned to the system with the remaining 80 barrels of crude oil and contaminated soil being properly deposed of. External notifications were made to nrc on july 15, 2017 at 12:18 cdt (#1184164) and the oklahoma corporation commission (occ) # 18517-ogd-010341. The nrc follow-up (#1184349) was placed on july 17, 2017 at 15:15 cdt.
