Permit Renewal Application: ID-9-0036 PIN: NS75-0006 Entergy Nuclear Vermont Yankee Vernon, Vermont

Dear Ms. Dewald and Mr. Wender:

As part of the review of the application for renewal of ID-9-0036, I have checked the effluent and groundwater data which was submitted. As you know, the groundwater data is used for determining compliance of the indirect discharges with the Aquatic Permitting Criteria. I have found several data entry errors and inconsistencies which should be corrected. While most of the errors are minor, including some data rounding discrepancies, it is important to have an accurate data set prior to subsequent calculations.

Only the pages of the summary report which need to be changed should be re-submitted. Upon receipt of a complete response to this letter processing of the application for renewal will continue.

I have also reviewed the text of "Summary of Effluent and Groundwater Monitoring Data 2000 - 2004" contained in Attachment 3 of the application.

Under Section 2.2 it is stated that Escherichia coli (monitoring) was added to determine the effectiveness of disinfection of the septic tank effluent. There is no disinfection of the septic tank effluent provided.

Monitoring for E. coli provides information on the removal of these organisms by passage through the biological mat in the leachfield and through unsaturated soils below.

Under Section 3.2 it is stated that TKN sampling for groundwater was replaced by sampling for N03/NO2 as N in 2003. Actually, the permit requires sampling only for nitrate nitrogen. See also the discussion for ammonia nitrogen (Section 3.8).

ID-9-0036 Permit Renewal Application August 12, 2005 Page 4 Thank you for pointing out the errors in the current permit under Section 3.14. These will be corrected in the permit renewal.

Ifyou have any questions regarding this letter, please feel free to contact me at 802-241-3824. Please be aware, however, that I will be out of the office until August 2 5 t.

PIN: NS75-0006 Re: Groundwater and Effluent Data Corrections

Dear John,

Thank you for summarizing the inconsistencies and errors you discovered in the five-year data summary tables included in Entergy Nuclear Vermont Yankee's IDP renewal application. In each case, the discrepancy, error, of omission has been reconciled. As you pointed out, many were the result of rounding to fewer decimal places than displayed on the laboratory data sheets while others were typos. In preparing the five-year summary for submission with the renewal application, I was unaware that effluent samples had been atypically collected in January 2001 but the data was readily available and I have included the summary table herein (Table 5). I have expanded your table by adding an additional column titled resolution and, as requested, am including the affected pages. The affected values within these pages are highlighted in purple.

Please call if you have any questions or concerns with this updated information.

Sincerely, 1I~J."e Lynt* DeWald Samuel A. Wender IV Environmental Specialist Chemistry Superintendent
