Narrative
At 7:17 on november 20, 2019, enterprise personnel identified a small pin hole leak inside the chime on tank 1024 in el dorado terminal that resulted in a 4 gallon release of gasoline. During the evaluation of the costs of emptying and cleaning the tank in order to perform analysis and repairs, it was determined that the costs would surpass $50,000 on november 21, 2019, making it a reportable nrc leak. The tank will remain out of service until it is inspected and repairs are made. Investigation and metallurgical analysis determined that under-deposit oxygen corrosion was the likely cause. Repairs are underway to return to service. A liner will be installed to prevent recurrence. Initial nrc update was placed on november 21, 2019 at 10:45. 48 hour nrc update #1264577 was placed on november 22, 2019 at 08:28.
