Narrative
After recently undergoing an API 653 inspection, tank 74 was being refilled when the release was discovered. Approximately 240 barrels of crude were released and completely contained within the tank dike. Product was cleaned up. As designed by the manufacturer, the water draw valve did not have an easy identifiable hard stop indication, which allowed the technician to break the welds and open the valve beyond the fully open position. The valve has been replaced. Note: a precautionary nrc report (#1177220) was made due to preliminary cost estimates being near $50,000. Additionally, a confirmation report (#1177386) was submitted within 48 hours to clarify that costs would not exceed $50,000 and therefore the initial nrc report was not required.
