Narrative
On 08/31/17 at approximately 07:55 local operating personnel discovered crude oil contained within the tank dike of 4701. The roof drain was closed and the release was stopped. After an inspection of the tank, no integrity issues were found with the floating roof. It has been determined that the roof drain was clogged which resulted in abnormal water accumulation on the roof causing crude oil to come up through the leg sleeves. At the time of discovery, the initial cost for repair and clean-up was estimated to be $20,000. Once a visual was placed on the floating roof that estimate was above the $50,000 threshold and the nrc call was immediately placed. 48 hour update number 1189123.
