Narrative
A release was discovered when field personnel arrived on-site to complete a facility inspection. The plug in the bottom of the unit 1 suction valve was blown out, which allowed the valve to leak. The crude had sprayed an area approximately 30 foot x 30 foot, with a total estimated volume of 3 barrels. The system was immediately shut down and the release stopped. The valve was replaced and the line was restarted. On january 6, 2017 mpl completed its investigation into the release. As a result of the investigation, mpl discovered that signs of corrosion were present on the internal threads of the valve body, but analysis could not be completed on the threaded plug as it was not recovered following the accident. Corrosion appears to have played a role in the drain plug failure.
