Long <br />Division Director <br />As per your request, I reviewed the information submitted by <br />western. Fuels Association, Inc. (WFC) for the New Horizon Mine. I <br />reviewed the original revision proposal, the Division's adequacy <br />comments and the WFC response to those comments. I also reviewed <br />the currently approved mining permit and the baseline data for many <br />of the wells located at this site. I have attempted to organize my <br />comments as they are proposed in the operators letter of September <br />27, 1995. <br />I concur with the elimination of the five groundwater wells <br />and the two surface water sites as defined by the operator in <br />items numbered 1-7. <br />I also concur, as Randy Price has done previously, with the <br />sampling frequency proposed by the operator. I will add that <br />due to this minimum amount of sampling, the operator will be <br />expected to conduct the sampling program with few, if any <br />misses. The Division should also review the data carefully to <br />determine if impacts are present and subsequently require <br />monitoring plan changes as appropriate. <br />3. I do not concur with the sampling parameters as proposed by <br />the operator. Apparently, there is no difference in sampling <br />parameters between surface and groundwater, which is <br />inappropriate. Given the minimum ameunt of samples collected, <br />it is important that the Division get a full-suite sample <br />which can be compared to baseline information. After review <br />of the information submitted by the operator and the baseline <br />data, I would approve of the following sampling parameter <br />lists. Please note the difference between dissolved (dis) <br />analysis vs. total recoverable (tot rec): <br />Groundwater <br />Alkalinity <br />Aluminum (dis) <br />Bicarbonate (dis) <br />Calcium (dis) <br />Carbonate (dis) <br />
