Mr. Berhan Keffelew <br />Division of Minerals and Geolobry <br />January 26, 1995 <br />Page No. 2 <br />The discharge permit has been designed in order to detect and control any point source discharges of process water. <br />The term "process water" includes any type of drainage from waste rock areas, regardless of the quality of that <br />drainage. Whether or not the discharge meets water quality standards is not a factor in de[emtining what is to be <br />permitted. Therefore, the standards are irrelevant in determining the need for a permit. Disposal of the material with a <br />high acid mine drainage potential will likely result in additional CDPS permit requirements. The Division of Minerals <br />and Geology should not factor the water quality standard into their decision on whether the material should be capped s. <br />I am unaware of a site where it has been possible to predict the quality of acid mine drainage. it is strongly <br />recommended that the DMG require that the materials be capped in such a manner as to ensure that the conditions for <br />acid mine drainage are not allowed to form. Failure to do so may well result in perpetual Vestment requirements at the <br />site. <br />We are enclosing information we obtain from South Dakota. We suggest that the material be handled similarly. <br />Sincerely, <br />~Q `~j <br />Patricia A.
