Exhibit D <br /> 6.3.4 Reclamation plan: <br /> (a) The Reclamation Plan shall describe the timing, procedures,criteria, and <br /> materials that will be used to reclaim the affected land to the proposed future land <br /> use.This Plan is correlated with Exhibit E— Map 6: <br /> (a) Specify at what point in the mining plan and to what depth(s) <br /> overburden will be replaced in relation to ongoing extraction: <br /> There is no overburden removal. Therefore, there will be no overburden to replace. What waste rock <br /> is generated may be given to Boulder County Road and Bridge Department and/or the U.S. Forest <br /> Service for use in road construction or used on-site. Any waste rock remaining at the conclusion of <br /> mining will be reclaimed in place and/or disposed underground, once the appropriate agency <br /> approvals are obtained. <br /> (b) Specify the maximum gradient of the reclaimed slopes(horizontal: <br /> vertical). If the Application proposes slopes steeper than 3:1,the <br /> Operator/Applicant must include a justification that supports steeper slopes <br /> for the proposed post mining land use, and demonstrates compliance with the <br /> applicable performance standards of Section 3.1: <br /> At the Idaho Tunnel hillside, the vertical slope is currently steeper than 3:1. However, as per <br /> approved TR No. 7, the final reclamation of the hillside will meet all slope requirements and <br /> Approximate Original Contour (AOC). The proposed road will meet slope requirements. Other <br /> than the hillside and the road, there will be no significant areas of reclaimed slopes. <br /> (c) Specify the measures that will be taken to revegetate the site,if applicable, <br /> including: <br /> (i) State the thickness of the plant growth medium to be replaced.Sample and <br /> analyze available soils sufficiently to establish quantity and quality: <br /> Plant growth medium will be replaced to a depth of between 6 and 8 inches. Most of the plant <br /> growth medium available for revegetation will come from soils located uphill, directly south of the <br /> surface facilities. This area will likely not be disturbed until final site reclamation. The topsoil <br /> removal area will then be regraded, prepared for seeding and seeded and mulched. <br /> The proposed areas of waste rock storage have historically been used for placement of waste <br /> rock in the past. As such, there is no topsoil in these areas to remove. In addition, the proposed <br /> road will be through an area where no soil is present. The proposed waste rock pile at The <br /> Caribou mine will remain a rocky area, as it was prior to mining. The existing access road will be <br /> left for the landowner's use. <br />
