The licensee provided the following in accordance with their operating license Appendix B, Environmental Protection Plan.
At approximately 2100 hrs. on 2/27/04, the Illinois Department of Natural Resources (IDNR) contacted Exelon corporate environmental personnel and informed them there was a fish loss on Clinton Lake. Corporate personnel notified Clinton Power Station personnel at 2130 hrs.
An inspection on the lake shoreline on 2/28/04 occurred from 0800 to 1200 hrs by station personnel.
The inspection revealed a total of several hundred deceased fish over several locations. The species predominantly observed were gizzard shad. As followup, the final tally of fish affected will be determined after further communication by CPS environmental personnel working with IDNR.
The fish appeared have been deceased 3-5 weeks, based on observed decomposition. This 3-5 week time period closely coincides with Clinton Power Station's shutdown on 2/3/04 for refueling outage C1R09.
The Licensee notified the NRC Resident Inspector.
