February 26, 1981 Mr. J. A. Hind, Acting Chief Division of Emergency Preparedness and Operational Support Region III, Office of Inspection and Enforcement U.S. Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, Illinois 60137

Dear Mr. Hind:

This is in response to the NRC letter, Mr. W. L. Fisher to W. C. Gerstner, dated February 6, 1981, which included a Notice of Violation and Inspection Report No. 50-461/81-02.

Illinois Power Company's response for the one item of non-compliance cited is as follows:

1. The notice of violation states, in part:

" Contrary to the above, no periphyton sample was collected at location 7 during the first quarter of 1979."

Two attempts were made to collect the winter sample at location 7._ On the first attempt, in February 1979, ice cover precluded obtaining the sample; this is documented in the field notebook. Zooplankton and phytoplankton samples were. collected at location 7 in March 1979; however, because of_ differences in sample collection methods, high water conditions prevented collection of the periphyton_sanple.

This was not documented in the field notebook. Later attempts to obtain the sample were not made because it was considered that the environmental conditions present were not representative of first quarter conditions.

To avoid further noncompliances of a similar nature, a checklist system, criginally implemented during the 3rd quarter of 1980 for the collection of fishery samples, has been expanded to include all types of biological samples. A master checklist-with all these samples for each quarter will be maintained in the field notebook for the sample type. Unsuccessful attempts to collect samples will be fully documented in the respective field notebook and noted on the master checklist. Subsequent attempts will be made throughout the. sample period to obtain

, the sample. .The expanded checklist _ system was implemented on February 25, 1981.

J. A. Hind Rebruary 26, 1981 NRC Page 2 The missed periphyton sample for the first quarter of 1979 is an isolated case; Illinois Power Company has been.in full com-pliance with the requirements for periphyton sample collection since the second quarter of 1979.

I hereby affirm that the information contained in this letter is correct to the best of my knowledge.

I trust that the above actions constitute an acceptable response and will satisfactorily complete our corrective action.

Sincerely,
