OFFSITE NOTIFICATION REGARDING A MINOR FISH KILL IN THE COOLING LAKE DUE TO INCREASING SUMMER TEMPERATURES
The following text is a portion of a facsimile received from the licensee:
"... this notification is being made pursuant to 10CFR50.72(b)(2)(xi) and Exelon Reportability Manual Section SAF 1.9. At 1528 CST on 07/21/01, 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 increase, the cooling lake temperature increased to 97°F, beyond the threshold at which point species susceptible to increased temperature begin to perish. It was communicated to the Illinois Department of Natural Resources that approximately 2,000 fish, mainly Gizzard Shad, had perished."
The licensee notified the NRC resident inspector.
