| Title | Environmental Impact During Service Water Mollusk Biocide Treatment |
| Event Description | During Service Water mollusk biocide treatment, divers in Lake Ontario found approximately 20 Goby fish dead near the intake structure. Nine Mile Point Unit 2 Operating License Appendix B, Environmental Protection Plan, paragraph 4.1 requires a 24-hour notification of any occurrence of an unusual or important event that indicates or could result in significant environmental impact causally related [to] plant operations. This fish kill may have been caused by the chemical injection line being dislodged above the intake structure. Chemical injection was secured when the mispositioned line was discovered. The New York State DEC [Department of Environmental Conservation] was notified in a related report of the unexpected injection site of the chemical.
The NRC Resident inspector has been notified. |
