Narrative
On august 7, 2020 at approximately 6:44 am cdt operations technicians discovered crude oil seeping up near valves 206-b-301 and 206-b-302 in manifold 206 within the cushing north terminal. After hydro excavation the source was determined to be a pinhole in the heat affected zone on the flange side of the weld between the tee fitting and flange connected to valve 206-b-301. The affected tee fitting was removed and blinds were installed. This section of pipe has been idle since it was replaced with a new manifold. Approximately 1 barrel of oil was released. All free oil was recovered and contaminated soils removed. A metallurgical analysis was completed and identified internal corrosion on the tee as the cause of the pinhole release.
