| "[The] decision was made today (08/17/00) at 1130 [CDT] to notify offsite    |
| agencies concerning a large fish kill at Prairie Island.  This [was the]     |
| result of the planned zebra mussel treatment that was taking place at the    |

| The licensee stated that the event occurred on 08/16/00 and that the fish    |
| kill involved approximately 7,500 young fish (mainly catfish and minnows     |
| approximately 2" to 5" in length).  The majority of these fish were          |
| discovered in the plant's recycle canal.  However, a few dead fish were also |
| 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.                   |

| 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.         |
