| Title | Notification to Sc-Dhec Concerning Exceedance of Biological Oxygen Demand (Bod5) Limit |
| Event Description | On January 28, 2009, the composite sample from our waste treatment facility analyzed by our NPDES certified vendor laboratory indicated that wastewater discharged from the Westinghouse Columbia plant (to Congaree River) during the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period contained 60.8 pounds of BOD5 (56 mg/l BOD5) which exceeded the Daily Maximum Permit Limit of 60 # of BOD5 per day. The daily average for BOD5 discharges during January was approximately 23.6 pounds per day and is within permit limitations (30 #/D). Other BOD5 results for the month were less than 12 # BOD5/day.
Following recognition of the problem on 2/3/09, Westinghouse immediately responded to evaluate the waste treatment facility including the sanitary package plant, the sanitary lagoon, process lagoons, and final discharge tanks. All systems were operating properly and producing clear effluent with no unusual odors or solids present. Waste treatment operations logs were inspected and no unusual problems were noted. All dissolved oxygen results for the month of January were greater than 10.0 mg/l indicating satisfactory performance of the wastewater treatment facility. Visual analysis of the entire waste treatment facility on 2/3/09 indicated that all processes were operating normally and no problems were being experienced. Investigation samples for BOD5 were collected on 2/3/09 from process source locations prior to the final discharge. All precursor investigation BOD5 samples were analyzed to contain less than 11.0 mg/l BOD5. Based on our information and discussions with [South Carolina - Department of Health and Environmental Control (SC-DHEC)], we are reporting the exceedance data, but believe the sample was anomalous (or contaminated) due to the lack of any elevated source of BOD5 (based on investigation samples) or process upsets noted in the entire waste treatment facility. Westinghouse remains deeply committed to continuous compliance with all NPDES requirements. |
