Pease provfde a description of the reclamation to be performed at <br />Waste Rock Disposal Area D. The upper surface of each waste rock <br />disposal area should be graded to encourage drainage in a cantroiled <br />menner, <br />RESPONSE: As discussed on page E-1, the reclamation to be performed at Waste <br />Rock Disposal Area D will be the same as previously approved for the <br />other waste rock disposal areas. This reclamation plan is as follows. <br />The dump will be treated with an overall 3H:1V outslope. This <br />outslope will be achieved during construction by end dumping to a <br />maximum 50 foot height and then placing a 75 foot setback to achieve <br />a 3H:1V overall slope. The dump outslopes will be regraded upon <br />completion. The outslopes will be graded to eliminate all but a 15- <br />ft wide (dozer width) area of each bench. This area will allow for <br />bench access and sediment collection and erosion control. The upper <br />surface of each waste rock disposal area will be graded to encourage <br />drainage. Where possible, the waste rock disposal areas will be <br />reclaimed concurrent with waste rock placement. As each lift 1s <br />placed, the outslope along with the previous bench may be reclaimed, <br />as long as the seasonal conditions permit reclamation. Topsoil will <br />be applied to the dumps. The areas for topsoil placement will be <br />prepared and seeded using the basic procedures outlined in the <br />approved permit, Exhibit E. <br />
