| Event Description | On October 14, 2008, Westinghouse received the vendor chemical laboratory analysis for the Total Suspended Solids (TSS) parameter result for the October 1st, 2008, NPDES liquid effluent 24-hour composite sample. The sample result indicated that the wastewater discharged from the Westinghouse Columbia plant to the Congaree River during the 24-hour period preceding the October 1st sampling contained 64.07 pounds of TSS, which exceeds the Daily Maximum permit limit of 64.0 pounds per day.
Preliminary information indicates the parameter exceeded the permit limit due to dredging of lagoon solids during the week preceding the October 1st sample. It should be noted that process samples taken the day before did not indicate a problem with TSS prior to discharge. Typical averages for TSS in 2008 are 12.3 pounds per day, which is well below the permit daily average limit of 32 pounds per day. The dredging campaign has since been completed, and the following weekly sample analysis (dated October 8, 2008), indicates that TSS values are back to normal, around 15 pounds. Liquid discharges from the Columbia Plant are regulated with regard to chemical pollutants through the SC-DHEC/EPA administered NPDES permit SC#0001848. WEC is required to notify SC-DHEC of non-compliance conditions which exceed any daily maximum effluent limitation. ' 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.' Liquid discharges from the Columbia Plant are regulated with regard to chemical parameters through the SC-DHEC/EPA NPDES Permit #SC0001848. Liquid effluent discharges are being temporarily halted while reviews are being conducted to verify no potential for recurrence of the event. The event will be entered into the plant's Corrective Action Process and a thorough review will be performed to identify the cause of the event. The problem was identified by Westinghouse EH&S personnel. At no time was the health or safety to any employee or member of the public in jeopardy. SC-DHEC has been notified. |
