ENS 42213 | 21 December 2005 02:15:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Minor Chemical Spill | Notified the Pennsylvania Department of Environmental Protection ( PA DEP) at 2115 of an onsite chemical leak, some of which ended up being discharged to the environment (Ohio River). A small hydrazine spill onsite was directed to the onsite chemical waste sump. The chemical waste sump was at that time being reprocessed to the water treating clarifier. The clarifier effluent is directed to filters and eventually to the onsite reverse osmosis unit and demineralizer train. The waste effluent of the reverse osmosis unit is directed to the clarifier settling basin, which in turn is routed directly to the Ohio river. The chemical analysis of the clarifier settling basin indicated 132 ppb hydrazine. The information reported to the PA DEP essentially stated that BVPS had a minor onsite chemical spill that is not EPA reportable. However, since hydrazine was detected in outfall 103 (The clarifier settling basin) under the requirements of the National Pollutant Discharge Elimination System (NPDES) permit we are required to report this to the PA DEP. We do not expect harm to the environment. No offsite emergency response is required. The licensee notified the NRC Resident Inspector. |
