steeper than 3:1. However, as per approved TR No. 7 (under Rule 6.5),the final reclamation of the <br /> hillsides will meet all slope requirements and Approximate Original Contour(AOC). If necessary, the <br /> stability of replace topsoil on graded slopes will be assured by roughing in final grading to eliminate <br /> slippage zones.The proposed road will meet slope requirements. Other than the hillside and the road, <br /> there will be no significant areas of reclaimed slopes.Areas adjacent to mineshafts and portals will be <br /> stable but may be steeper than 2:1. Runoff along slopes will be controlled with erosion and sediment <br /> control structures to minimize rill and gully on slopes (See Exhibit D, Section 1. 12). <br /> Because this is an underground mining operation,there will be no highwalls.There will be some rock <br /> faces where shafts occur(an existing shaft and the Cross Mine Decline portal).Grading will be <br /> conducted on the contour where it does not pose a safety hazard to operators and equipment. <br /> During site reclamation, BMP storm water control practices will be in place to control erosion and <br /> siltation. Slides and other damage should not be a factor since only small areas will likely need to be <br /> graded. <br /> 1 .11 Remaining Site Features <br /> The following mine components will remain after reclamation: <br /> Main Parking Area New Potable Water Pipe <br /> Secondary Parking Area New Sanitary Water Pipe <br /> Subsurface Drinking Water Supply Line Existing Septic Tank and Leach Field <br /> Offices and Dry Room Cross Shop <br /> Cross Cabin Cross Ore Building <br /> NOAA Shed Munitions Bunker(North) <br /> Hazardous Materials Shed Caribou Conex Storage Bay <br /> New Septic Tank and Leach Field <br /> Wildlife use will be incidental and not part of the post mining land use. <br /> 1 .12 Erosion Control Features <br /> The surface areas that will require stabilization include any remaining waste rock piles, areas around the <br /> ponds and stream, and other areas where buildings have been removed. Appropriate storm water <br /> controls will used to retain and filter runoff sediment from the piles. Any exposed areas not disturbed by <br /> on-going mining operations will be seeded with the topsoil mix. All roads and parking areas will be <br /> surfaced with appropriately sized waste rock or purchased crushed rock. <br /> All remaining ditches and sediment control facilities will be reclaimed following the specifications in this <br /> amendment and applicable Mined Land Reclamation Board regulations. <br /> All storm water control structures and facilities will be removed and the areas reclaimed once the major <br /> areas of site reclamation are successfully revegetated and stabilized so that storm water controls may <br /> 11 <br />
