Narrative
At approximately 22:15 on 7/16/19 a release was identified by operating personnel at the texoma manifold sump. While making an inbound delivery switch to tank 1533 the facility line shut down due to overpressure. Preceding the overpressure, valve t385 was given an open command by local control center and indicated an open status shortly after. With open path available the operator then closed off prior delivery line up to make the switch to tank 1533. The pressure relief valves on the line activated flow into the sump and the delivery shutdown. The rate of relief overwhelmed sump pump capacity and it overflowed releasing approximately 4 bbls of crude. Osro crews were dispatched to clean up free product and remove contaminated soil for onsite remediation. Investigation revealed that the valve stem on valve t385 had separated from the gate allowing the stem to move to an open position and trigger open position status in scada. The valve is awaiting replacement and line up has been configured as to bypass this valve in the interim period until replacement. Upon removal the valve will be inspected for determination of cause of stem separation. Supplemental report will be filed after investigation is complete. Supplemental information - the valve was replaced and the failed valve was examined for cause of stem separation from gate. It was determined by visual analysis that the separation between the valve stem and gate was due to metal fatigue.
