Title | Spill of Sewage Sludge |
Event Description | At approximately 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on November 19, 2007, waste treatment operators noticed that the sewage sludge pump transferring material to the LLR press, located at the Waste Treatment Facility, had split and that sludge material had been released. The volume of sludge material that was released is estimated to be less than 150 gallons. The material was released in the pump house and flowed to a gravel area north of the pump house and extended into a storm water drainage ditch. A small quantity of material appeared to collect in the ditch, but did not flow off-site. Operators contained the spilled material and cleaned the affected areas in less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
Facility sewage is of low activity due to natural content and the possible presence of trace material due to trace contamination in the associated piping system. The material is known to be << [much less than] 30 pCi/g [picoCuries per gram]. The total activity spilled including natural background is estimated to be less than 6 uCi [microCuries] using a maximum concentration of 10 pCi/g and 150 gallons of material. Both values are conservative. A study is in progress to determine if licensed material was actually present. On November 20,2007, as required by our VPDES Permit Number 0003697, the Virginia Department of Environmental Quality was notified of this non-permitted release to the environment. BWXT is making this concurrent notification in accordance with 10 CFR 70 Appendix A(c). There was no other potentially hazardous material released. The licensee notified the NRC Resident Inspector. |
