My comments <br />regarding the groundwater portion of the AHR were forwarded to you <br />earlier. <br />1) The page numbering system for the data pages is very <br />confusing and makes it hard to find the page that one is <br />looking for. In future reports, it would facilitate <br />review, both by the Division and the public, to use <br />"normal" page numbers (e.g. 1,2,3, etc.) <br />2) On page 2 of the AHR, the operator reference a <br />conductivity-tons/a.f. ratio used to convert E.C. <br />readings to TDB. The operator should show how this <br />conversion was arrived at (i.e. provide the calculations) <br />so that the Division can verify the results. Also, the <br />operator should define "a.f.". <br />3) Table M94-2 should indicate the units for conductivity <br />and Mass Avg. <br />If you or the operator have questions, please call. <br />
