Narrative
Nustar pipeline control center was notified of visible vapors above the ground near valve site 5-10 in marion county, missouri. Nustar employee arrived on site and confirmed leak. Work crew arrived on site, excavated and found buried stopple tee leaking from side seam weld. Plans were then made to weld on additional stopple tees to allow from removal of failed existing stopple tee. Estimated release volume is 10 barrels or less. Line segment was immediately shut down and isolated. All appropriate internal notifications made. External regulatory notification to nrc was made. 190 cubic feet of soil was removed and taken to the nustar center station location to be land farmed. This stopple tee was installed by a contactor in 2000. Currently our welders are nustar employees who are trained and skilled in detecting similar issues that would lead to weld failure.
