Patrick, Thanks again for your attention to this matter. The proposed report looks good with the following comments:

- Each report should be annotated similar to your explanation in your 9-12-06 e-mail.

- As discussed during our conference call, where samples are drawn from different levels there will be a separate report for each level as if each level represents a different well.

- Each report should indicate the current sampling frequency or next tentative sampling date.

- Well location should be categorized in each report and reports grouped accordingly, e.g. offsite, onsite perimeter, onsite interior, along river, relation to spent fuel rod pools, etc. You may have your own better convention. Tim Rice had suggestions.

- The reports should include a cover sheet which identifies, categorizes, and indicates status of, e.g. proposed, under construction, fully developed, etc., all monitoring wells.

At what point would you recommend another conference call?

IPEC Stakeholder Bi-Weekly Well Report

JLEug.ýn!ý_qq!jýy - Fwd-._EW. IPEG Stakeholder Bi-Weekly ell He Pagle 2 11

- Fwd: FW: PEG Stakeholder Bi-Weekly Well Report Paqe 211 Sirs, Attached please find the revised IPEC Groundwater Investigation Bi-Weekly Update. This nascent report was created in order to provide monitoring well data to the stakeholders in a manner that hopefully will assist the reader in understanding the monitoring well data both in both tabular form and graphically. We are attempting to create a single report that all will find useful. Our intention is to update this report the Wednesday preceding the scheduled bi-weekly stakeholder call on Thursday. This report will contain a data chart and data table of each wells particular data. The chart will more easily show data trends and how the data relates to the maximum concentration level (MCL). The data table will provide all sample results through present, including numerical result, associated sample error (standard dev), the minimum detectable concentration (MDC) and the ratio of result to MCL (fMCL). There will be two pages for each sample location. One page for Tritium results and one page for Strontium results.

Included are two examples of how a typical page will appear. The MW-34 chart shows how a well containing elevated concentrations of H3 would appear in addition to the identification of a trend in the data. Comparing this to MW-40 we see that wells close to background or having results less than the minimum detectable concentration will still have results plotted reflecting the 'non-detect' or background level of those results.

Please review these example pages and provide feedback, as necessary.

As for the tomorrow (Wednesday 9/13) we will provide the report in it's original state until such time as we can finalize this newer revision.

Sincerely,

<<MW-34 H-3 MCL.pdf>> <<MW-40 H-3 MCL.pdf>>
