Subject:
Byron Station' Radiological Environmental Monitoring Program NRC Dockets 50-454/455
Dear Mr. Keppler:
The Radiological Environmental Monitoring Program for Byron Station i
has been revised. During a recent in-house quality assurance audit, it was noted that the control dairy farm in the environmental program was improperly placed. The control dairy has been changed to adhere to the Radiological Environmental Technical Specifications. The new dairy, BY-17, is located in the least prevalent wind direction, approximately 9 miles from the station.
A copy of the revised Radiological Environmental Monitoring Program for Byron Station is attached.
If you have any questions concerning this change, please feel free to call.
Sincerely.
Irene M. John Nuclear Licensing Administrator enclosure cc:
