Lnchhearl <br />Executive Dueclor <br />Michael B. long <br />^ivi Sion D~reaor <br />As per your request, I reviewed the information submitted by Jim <br />Stover concerning his re-iteration of our meeting of April 7, 1995. <br />My comments are as follows: <br />1. I believe that the full suite parameter lists for both surface <br />and groundwater should include hardness due to the more <br />prevalent use of Table Value Standards (TVS) in water quality <br />determinations. <br />2. I recall discussing that if the mine was to be located in the <br />D seam that the B seam could potentially be monitored as the <br />first aquifer below the lowest seam to be mined and the <br />Rollins could be monitored From the existing well at a minimum <br />frequency. Reading Jim's memo, I am not sure whether or not <br />he is currently thinking along these lines. <br />Other than the above, I agree with his re-iteration. If you have <br />questions let me know. <br />
