Title | Offsite Notifiection Due to Inadvertent Chemical Discharge |
Event Description | At 1920 [EST] on 2-19-11, a chemistry technician notified the Shift Manager that more than the expected amount of Sodium Bisulfite was inadvertently added to the Circulating Water System discharge. The Spill Prevention Control & Countermeasures (SPCC) Plan was referenced for required actions. 17 additional gallons of Sodium Bisulfite was discharged to surface waters of Lake Michigan. This amount of Sodium Bisulfite is less than the reportable quantity of 417 gallons per the SPCC Plan. However, since it was released to surface water (Lake Michigan), a notification to the District Water Quality Division (DWQD) was made at 2020 [EST] by the site's Senior Environmental Specialist (SES). The DWQD requested that additional notifications be made to state (Pollution Emergency Alert System - PEAS) and local (911 operator) agencies. PEAS was notified at 2020 [EST] by the SES and Van Buren County dispatch (911) was notified by the Control Room staff at 2047 [EST].
The licensee notified the NRC Resident Inspector. |
