| ENS 55566 | 8 November 2021 13:05:00 | At 1015 CST, a report was made to the State of Nebraska Department of Environment and Energy (NDEE) based on the analytical report for soil samples from the area surrounding the removed FO-10, Auxiliary Boiler Fuel Oil Storage Tank. The tank was removed as part of Fort Calhoun Station decommissioning and soil samples were tested due to historical information from a similar tank removal earlier this year (June 2021). The soil contamination levels are from the historic use of the tank. The contamination levels (of Volatile Organic Compounds) are above the lab reporting limits and thereby reportable to the State of Nebraska Department of Environment and Energy. There was no contamination noted in the groundwater samples. The NDEE will determine what, if any, remediation may be required. The state NDEE requested the District utilize their Spill Form because this is the simplest method of State notification for tanks exempted due to 40 CFR280.10(c)(4). No active petroleum spills are in progress and appropriate remediation actions will be taken in accordance with Nebraska State regulation and guidance. The licensee will notify NRC Region 4 personnel. |
