<br />However, the New Elk and Golden Eagle Mines do affect cumulatively the flow in <br />the Purgatoire River and the alluvial aquifer system. It was noted in the <br />Findings Document for these two mines that due to the poor quality and limited <br />use of water in the area these effects will have little impact on the <br />surrounding water use. It was also determined that the degradation of water <br />quality in the aquifers will not impact ground water use. <br />The assessment of the probable cumulative impacts of all anticipated coal <br />mining in the area on the hydrologic balance, as described in Rule 2.05.6(3), <br />has been made by the Division and the operations proposed in the application <br />have been designed to prevent damage to the hydrologic balance outside the <br />permit area. <br />The proposed operation is in compliance with the requirements of this section. <br />XI. Climatological Information and Air Resources - Rules 2.04.8 <br />n nr ni n~i~~ n nr rii~ ~-.~ n i~ <br />The climatological section can be found in Section 2.04.8 of the permit <br />application. The applicant has obtained an initial approval for emission <br />permit from the Colorado Department of Health. <br />The proposed operation is in compliance of this section. <br />XI I. Soils- Rules 2:04:9; 2:U5;3(5); 2:05;4(2)(d) and 4.06 <br />Baseline soil information is presented on pages 2.04.9 (pages 1-5) of Volume I <br />and Exhibits (H) and (G) of Volume III. Information regarding topsoil removal <br />and storage is provided on Sections 2.05.3(5) and 2.05.4 of the permit <br />application Volume I. The two major types of soil at the proposed Rimrock <br />mine are the Ayon and Capulin Groups. The A and B horizon soil types from <br />each soil group were sampled and analyzed by the CSU soil testing laboratory <br />for pH, texture, Iron, Copper, Calcium, Magnesium, Sodium, Zinc, Phosphorus <br />and sodium adsorption ration (SAR). The A horizons averaged 6 1/4" in depth <br />in the four test locations. Since 15" of topsoil is required for reclamation <br />the Division has agreed with the operator to salvaging all of Lhe A and B <br />horizons of the Capulin soil and only the A horizon of the Ayon soil. In <br />addition, soil in ephemeral drainage bottort~s which averages up to 60" deep <br />wiii be salvaged. The addition of the drainage bottom soil, which is <br />considered to be suitable topsoil, will be sufficient to satisfy the 15" <br />topsoil cover required for the reclamation. This trans]ates into <br />approximately 10,775 cubic yards of Ayon soil and 32,260 cubic yards of <br />Capulin soil plus streambed soil Since the operator will be stripping only 1 <br />1/2 acres at a time and direct hauling it to backfilled areas there will be <br />one topsoil stockpile northeast of the pit area (Exhibit KK). It will be the <br />only topsoil pile in the permit area. <br />The applicant has demonstrated that sufficient suitable topsoil materials are <br />available to reclaim the area with an average depth of 15" of topsoil. <br />The proposed operation is in compliance with this section. <br />- 15 - <br />
