Title	Offsite Notification to State Required by Npdes Permit for a Bypass Discharge
Event Description	{{#Wiki_filter:Facility: Westinghouse Electric Company LLC (WEC), Commercial Fuel Fabrication Facility, Columbia SC, low enriched (less than or equal to 5.0 wt.% U-235) fuel fabricator for commercial light water reactors. License: SNM-1107. Time and Date of Event: March 11, 2012 approximately 0900 Reason For Notification: On March 12, 2012, the Westinghouse Environmental Engineer was notified that the level readings of the South Lagoon indicated that a leak has developed in the South Lagoon liner. This liner was recently replaced. The South Lagoon is one of the lagoons used for settling solids from treated process wastewater prior to discharge. As the lagoons are located downstream of the Columbia plant wastewater radiological treatment systems, the wastewater in the lagoons is below the 10 CFR Part 20 radioactive materials discharge limits. However, the final discharge monitoring station required by the permit for chemicals are located downstream of the settling lagoons and such a leak is therefore an unanticipated bypass. The current sample analysis of the South Lagoon wastewater reflect the activity is < 4.6 x10 (-7) �Ci / ml and chemical results are within permit limits. Liquid discharges from the Columbia Plant are regulated with regard to chemical pollutants through the SC-DHEC/EPA administered NPDES (National Pollutant Discharge Elimination System) permit SC#0001848. Westinghouse is required to notify SC-DHEC of unanticipated bypass conditions in accordance with Permit. Notification to NRC is being made based on 10 CFR70 Appendix A, Section (c) Concurrent Reports: ' Any event or situation, related to the health and safety of the public or onsite personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made shall be reported to the NRC Operations Center concurrent to the news release or other notification.' As Found Condition: See reason for notification. Summary of Activity: - Liquid inflows to the South Lagoon have been rerouted to other authorized locations - Westinghouse is emptying the South Lagoon through the normal monitored effluent discharge point. - The liner vendor has been contacted and arrangements are in progress for the vendor to conduct necessary inspections and repairs as soon as practicable. - Westinghouse has initiated additional monitoring of the wells in close proximity of the South Lagoon to better assess any potential environmental impact. - The event has been entered into the plant's Corrective Action Process and a thorough review will be performed to identify the cause of the event. Conclusions - The problem was identified by Westinghouse personnel. - At no time was the health or safety to any employee or member of the public in jeopardy. - SC-DHEC has been notified. }}
