Narrative
Due to very heavy rains in the area of the facility over the course of a couple of days, the weight of the excessive water on the external floating roof exceeded the drain capacity of the storage tank roof drain system causing the roof to sink below the crude oil level in the tank at the time. A post-accident investigation performed by hmt, inc. Revealed no evidence of the roof drain being plugged up, or partially plugged up, and the drain valve at the bottom of the tank was operated in the normal, open position to allow rainfall to drain off the roof. When the crude oil got on top of the external floating roof, the reported volume drained out of the tank from the roof drain valve near the bottom of the tank. All released crude oil was completely contained within the tank's dikewall and none left the facility property. A second nrc notification was made regarding this accident. The second notification was made at 08:37am on 10/27/15. It was assigned report # 1131792.
