Narrative
As crews were excavating yard piping at gasconade station, they noticed a small amount of oil on top of the 6" drain line that runs to the sump near the unit #4 suction line. Directly above where they noticed the oil is a 2" threaded elbow, where it was confirmed the oil came from. As the station technician was on his way to shut down unit #4, the nipple gave out and oil started filling the excavation area. Gasconade station was locked out and the control center contacted in order to bypass the station. Approximately 60 gallons were released into the ditch. The free product was collected and the contaminated soil removed from the excavation area. The repair was completed by removing the failed pipe section and installing a schedule 160 2" plug on the welded threadolet at the bottom of the unit 4 suction header, and on the 2" elbow to the 6" drain line.
