Narrative
On wednesday, may 19, 2021, at 1500, medallion's control center operator noticed what appeared to be a spill on the camera system during the afternoon review of the system. The control center immediately reviewed the station's scada screens and alarms but did not find an indication of a leak. On-duty controllers then dispatched field personnel to investigate. A leak was confirmed and isolated at 1525 by local operations personnel. The manual valves on each side of the 3" bypass control valve were closed to isolate the leak. The control center notified the medallion response team of the incident. The initial response team arrived on location and completed delineation of the spill volume, and determined the leak met the accident reporting requirements at 16:45 on may 19. The investigation indicates that the initial release occurred when the composition gasket on a 3" control valve manufactured by cvs controls ltd failed, model v-100. The failure was the result of normal wear of the gasket located on the bottom of the valve. To prevent recurrence operations personnel replaced the v-100 3" control valve with a control valve that does not have the composite gasket orientated in the same position, reducing the potential for wear on the gasket. Soil remediation continued at the site until thursday, june 10th. Soil samples confirmed the contaminated soil has been removed and remediated to meet closure requirements. All of the released crude oil was recovered via vacuum trucks and soil remediation.
