Exhibit Page 17 <br />backfill as the initial step in reclamation, to create stable slopes, cover shale overburden, and provide a <br />relatively smooth terrain suited for grazing. This will include filling ravines to expand the top of the mesa, with <br />suitable toe stable slopes. Backfilling is expected to vary from 1 to 30 feet in depth, based on needs. See <br />cross-sections in Exhibit E-1. If backfilling is done in areas that are not mined, vegetation and sufficient topsoil <br />to replace topsoil on the backfilled area will be removed prior to backfilling. <br />Grading to control erosion, siltation and prevent damage (3.1.5(3)) <br />Grading will be done so that erosion and sediment is controlled on affected lands and so that there is no <br />damage to areas outside the effected land. All highwalls (mining faces) will be eliminated, and final slopes will <br />be below the angle of repose to prevent potential slides or other damage on affected lands or outside the permit <br />boundary. Temporary grading, including berms, rock check dams, swales, etc. may be incorporated during <br />mining and reclamation as necessary. As much as possible, there will be no discharge from disturbed areas. <br />Reclamation, as much as possible, will result in a series of closed basins with small (1 acre or less) recharge <br />basins, rather than having all water flow off the mesa top. In some cases, existing ravines will be filled with <br />excess overburden to create larger upland, relatively flat areas, for grazing land, and to reduce erosion <br />downstream. <br />Performance as soon as feasible (3.1.5(4)) <br />For most of the affected area, the time between initial disturbance and final reclamation will vary from five years <br />to one year. Because of requirements for work areas (see Mining Plan), some areas will have reclamation <br />delayed until suitable and sufficient area to relocate plant and stockpile areas is available. Backfilling, grading, <br />and placement of topsoil should be accomplished within one year of completion of extraction and relocation of <br />any work areas (including stockpiles) from a given area, with seeding to follow as soon as possible based on <br />recommendations (See Exhibit J). <br />Refuse and acid•forming or toxic producing materials (3.1.5(5)) <br />No acid-forming or toxic producing materials are anticipated to be exposed, mined, or processed at this site. <br />Any excess materials after crushing and screening, including product not processed or sold at the time of <br />closure, will be incorporated into backfill, except for any stockpile of material left for landowner use after <br />reclamation and release. <br />Holes, etc. (3.1.5(6)) <br />There are no drill holes, auger holes, adits or shafts to reclaim. <br />Maximum slopes (3.1.5(7)) <br />All areas, including basins, former headwalls, and berms, shall have slopes not exceeding 3H:1V. Slopes as <br />proposed are compatible with surrounding conditions and land use. <br />Use of farm equipment (3.1.5(8)) <br />As pastureland, no use is anticipated, but slopes are compatible with such use in the area, such as mowing, <br />seeding, or weed control. <br />Notice of other backfill (3.1.5(9)) <br />The Applicant will comply with this requirement to notify the Division if other backfill is used. <br />Prevention of unauthorized release of pollutants to surface water (3.1.5(10)) <br />The Applicant will handle mined material to be disposed of on-site in a way to prevent unauthorized release of <br />pollutants to surface water, and comply with this requirement. <br />Prevention of unauthorized release of pollutants to groundwater (3.1.5(11)) <br />The Applicant will handle material mined, handled, or disposed of on-site in a way to prevent unauthorized <br />release of pollutants to groundwater, and comply with this requirement. <br />General water hydrology and water quality (3.1.6(1)) <br />Hydrology and water quality issues are addressed at length in Exhibit G. The Applicant will comply with <br />applicable water and water rights laws and regulations, and water quality laws and regulations. No dredge or fill <br />in waters of Colorado or the United States is proposed, and no temporary or large siltation structures will be <br />placed except as required by pennits, and will be removed in accordance with those permits. <br />
