<br />Revision q3- Page I I of 30 <br />meet the Colorado Department of Public Health and Environment's requirements for <br />a discharge permit. Construction of the settlement pond will not damage adjacent <br />properties or structures <br />(3) All surface areas and stockpiles will be protected against wind and water erosion. <br />Surface areas will be kept moist, or sprayed with magnesium chloride, to control <br />airborne pollution, and all surface areas within the site will be graded to provide <br />positive drainage towards the mine area or site retention pond. <br />3.1.7. Groundwater <br />The applicant has obtained a CDPS /ndustrial General Permit jor Sand and Gravel <br />Mini»g and Processing General Permit from the State of Colorado Water Quality <br />Control Division. The applicant will also obtain the Colorado Division of Water <br />Resources Grave! Pit Wel! Permit. The operator will comply will all permit limits <br />established by the State Agencies for these permits. <br />3.1.8. Wildlife <br />The site currently has minimal vegetation and offers little cover for wildlife species. The <br />Division of Wildlife has provide documentation which indicates the project will not <br />impact threaten or endangered species, and is not critical habitat. <br />3.1.9. Topsoiling <br />(I) The top two to six inches of soil will be removed and stockpiled in the buffer areas <br />adjacent to the mining block areas. The topsoil shall be graded such that <br />precipitation runoff is directed to the mining or retention pond area. No toxic or <br />acid-forming materials are expected to be encountered during the mining operations. <br />Therefore, no contamination with these types of materials is expected. If, in the <br />course of impotting fill to the site, material batter suited for topsoil growth medium <br />is imported, the imported soil should replace the equal amount of stockpiled topsoil <br />and the replaced soil should be used as backfill. <br />(2) Woody vegetation at the site consists of greasewood. This material will not be <br />incorporated into the topsoil used for site reclamation. <br />(3) Stockpiles of topsoil will be placed in the buffer areas adjacent to the mining area, <br />and will be the locations that will have the least amount of activity occurring during <br />the mining operations. <br />(4) The topsoil will be stockpiled adjacent to areas that will require reclamation, <br />minimizing the amount of disturbance requved. <br />(5) Slope stability concerns will not be an issue at this site, as no steep slopes are <br />anticipated or proposed. <br />(6) The "most" suitable topsoil material, the top two to six inches, is being utilized for <br />topsoil replacement. In addition, certified weed free mulch will be applied at I to 1.5 <br />tons per acre will be incorporated into the topsoil. <br />(7) Fertilizer application will be required for reclamation. The Soil Conservation <br />Service has provided us the recommended fertilizer rates based from actual soil <br />samples taken from the site. <br />(8) All topsoil materials will be spread evenly across the site, such that no piles of <br />material are left on the project site. <br />3.1.10. Revegetation <br />(I) The reclamation seed mix will provide for a diverse, low maintenance, soil cover <br />material capable ofself-regeneration. The proposed seed mix far exceeds the <br />present, and surrounding vegetation, which are primarily noxious weeds. <br />(2) The site will not be reclaimed as forest planting. <br />(3) The site will not be reclaimed for rangeland. <br />(4) The Soil Conservation Service was contacted and provided the original <br />recommended reseeding species, which was all Tall Wheatgrass. The seed mix has <br />
