CONFIRMATORY SURVEY OF THE GROUP E EFFLUENT DISC'MRGE PATHWAY AREAS, FORT ST. VRAIN NUCLEAR GENERATING STATION

Dear Mr. Fuller:

The Nuclear Regulatory Commission staff has reviewed the Oak Ridge Institute for Science and Education's April 10, 1997, report entitled " Interim Letter Report-Confirmatory Survey of the Group E Effluent Discharge Pathway Areas, Fort St. Vrain Nuclear Station, Plattville, Colorado." The results of the survey show that one sample collected in Section D, at Flag 157, exceed the site guideline v:. lues. The sum of the fractions calculation for Co-60 and Cs-137, at this location, resulted in a value of 1.9. Please provide evidence that the averago contamination levels in these areas meet the averaging criteria in Draft NUREG/CR-5849.

If you have any questions, I can be contacted at (301) 415-6702.

Sincerely,lAL
