| kill involved approximately 7,500 young fish (mainly catfish and minnows |
| approximately 2" to 5" in length). The majority of these fish were |

| found in the Mississippi River. |
| |
| The licensee notified both the state and Goodhue County. The licensee also |
| plans to notify the NRC resident inspector. In addition, a press release |
| may be issued because this may be a media sensitive event. |

| PLANNED OFFSITE NOTIFICATION REGARDING HIGH EFFLUENT CHLORINE CONCENTRATION |
| IN THE SEWAGE TREATMENT PLANT OUTFALL |
| |
| The licensee stated that the sewage treatment plant effluent chlorine |
| concentration exceeded the SPDES permit allowable limit of 2 ppm. The |
| chlorine concentration was measured at 20 ppm. Preliminary evaluation |
| indicates that chlorine was improperly diluted when the supply tank was |
| recharged. The duration that the effluent chlorine concentration exceeded |
| the allowable limit is currently estimated to be no longer than 4 hours. |
| The sewage treatment plant outfall ultimately leads to Lake Ontario. |
| |
| The licensee plans to notify the New York State Department of Environmental |
| Conservation. The licensee has notified the NRC resident inspector. |
