| Title | Reportable Quantity of Waste Acid Released Onsite |
| Event Description | A second-shift Waste Treatment operator discovered acidic wastewater (a mixture of nitric acid, hydrofluoric acid and water) discharging from a sump on the Bay 5A Pickle Acid Scrubber pad at approximately 10:30 PM on 10/16/2007. The acidic wastewater ran downhill onto the roadway to the north and eventually onto a concrete pad near the bottom of the hill. By the time of the discovery, or very shortly thereafter, the overflow stopped. The operator notified area supervision and verified that all valves and pumps at the Waste Treatment facility were functioning normally and wastewater was being received in the equalization tanks.
Estimates on 10/17/2007 by Environmental Engineering of the amount of flow discharged to the line versus the amount received at Waste Treatment, combined with visual observation of the spill area, suggest that approximately 275 gallons of acidic wastewater were released from the trench, of this amount, approximately 25 gallons potentially reached uncovered surfaces adjacent to the road (gravel/grass). This was deemed to be a Reportable Quantity of a hazardous substance and appropriate notifications were made to the National Response Center (Notification #851841), the EPA Region 11 Consent Order Coordinator and the Virginia Department of Environmental Quality. The spill area was neutralized with soda ash and thoroughly rinsed. The small gravel/grass areas that may have been impacted are being assessed for additional remediation as necessary. BWXT will notify the NRC Resident Inspector. |
