Title | Offsite Notification to North Carolina - Rain Caused Overflow of Holdup Pond to Catawba River |
Event Description | Notification is to be made to an offsite agency: North Carolina Department of Environment and Natural Resources [NCDENR]. Due to heavy rains on site, a holdup pond overflowed to the Catawba River. Holdup pond overflow included chemicals (Rotenone) used to treat macro fouling in the Standby Nuclear Service Water Pond. Notification to NCDENR will be made by telephone Saturday morning 6/29/13.
The licensee notified the NRC Resident Inspector.
Due to continued rains on site, the holdup pond continues to overflow to the Catawba River. The overflow includes a new chemical, Potassium Permanganate, used to neutralize the Rotenone treatment of the Standby Nuclear Service Water Pond. This new chemical has the potential to initially turn water purple, which is normal when applied. The North Carolina Department of Environment and Natural Resources (NCDENR) has been updated. The licensee notified the NRC Resident Inspector. Notified R2DO (Freeman). |
