This is a concurrent report of a 24-hour report that was made to the
Tennessee Department of Environment and Conservation (
TDEC) regarding an unauthorized storm water discharge. As permitted by the State of
Tennessee, emulsified vegetable oil was being injected into ground water wells located on the North Site of
NFS property. At approximately 11:00 [EDT], Environmental Safety was notified of a cloudy oil substance that was observed in the west storm water ditch. Injections were immediately ceased and immediate corrective actions were implemented. Oil absorbent pads and socks were deployed and samples were collected. Before noon on 8/29/2018, the cloudy substance was observed at the discharge of the storm water ditch into Martins Creek. Because of the discoloration observed at the entrance to Martins Creek, this event required a 24-hour notification to
TDEC (made at 16:15 on. 8/29/18) and a five day written report will be submitted. Analysis of the
grab samples indicated no radioactive material release.
The licensee notified the NRC Resident Inspector.
