| Title | Environmental Event - Unusual Fish Kill |
| Event Description | Unusual fish kill on both unit's intake trash racks. Approximately 80-100 Skate (Cow Nosed Rays) dead on intake racks. The apparent cause was low oxygen levels in the bay water. This event appears to be an unusual environmental event per CCNPP's NPDES permit paragraph N, page 12 for impingement. This event is reportable per Tech Spec Appendix B Section 4.1 for significant environmental events.
The licensee contacted the Maryland Department of the Environment. The licensee will notify the NRC Resident Inspector.
Update: Unusual fish kill on both unit's intake trash racks. Approximately 80-100 Skate (Cow Nosed Rays) dead on intake racks. The apparent cause was low oxygen levels in the bay water. This event initially appeared to be an unusual environmental event per CCNPP's NPDES permit paragraph N, page 12 for impingement. Upon further review, the unusual environmental event threshold was not met since the fish kill was not substantial enough to cause a modification to plant operations. This event is reportable per Tech Spec Appendix B Section 4.1 for significant environmental events. Correction: The Maryland Department of the Environment notification will follow within 30 days per the NPDES permit [and therefore being reported per 50.72(b)(2)(xi), Offsite Notification, by the licensee]. The licensee notified the NRC Resident Inspector of this update. |
