| Title | Offsite Notification Due to Minor Fish Kill |
| Event Description | {{#Wiki_filter:At 1300 CDST on 06/28/05, it was discovered that a minor fish kill took place in LaSalle County Nuclear Station's cooling lake, due to increased temperature. As summer air temperatures increased, the cooling lake temperature increased above 95�F, the threshold at which species susceptible to increased temperature begin to perish. It was communicated to the Illinois Department of Natural Resources, that approximately 300 fish, the majority of which were striped bass, had perished.
This notification is made in accordance with Exelon Reportability manual SAF 1.9, ENV 3.26, LaSalle County Station Facility Operating License Appendix B Section 4.1 'Unusual or Important Environmental Events,' and 10CFR50.72(b)(2)(xi). The licensee notified the NRC Resident Inspector. }} |
