Narrative
During a routine switch from tank #15 to tank #18 at colorado city, the mov on tank #18 failed due to a stripped valve stem nut. Therefore the valve was showing to be in the open position for scada yet was actually closed. This event triggered the manifold relief system and oil backed up the thermal relief line into an atmospheric funnel for the relief valve used for sampling and onto the concrete containment. The mov was repaired and the thermal relief valve funnel was removed and replaced with piping to the sump drain line. The system was evaluated for any additional atmospheric thermal relief valves and all valves were replaced with piping to the sump drain line.
