Accident Classified As: Below Reportable Quantity (BRQ)
The external floating roof on the Tank 1 crude tank sunk and exposed contents of the tank to the environment. A leak developed from Tank 1 floor area and released oil to the ground inside of the containment area. Foam was applied to the top of the tank to mitigate potential vaporization of hydrocarbons. Mitigation efforts are ongoing to empty the tank and the majority of oil has been emptied from the tank. Water has been successfully introduced to vessel to float the oil later off the tank floor. Currently, oil is no longer leaking to the ground.
Root cause investigation has not been completed. Follow-up report will be submitted within 60 days.
