• <br />• <br />prior to mining. The existing access road will be left for the landowner's use. However, the <br />location of the proposed leach field will be stripped of topsoil. Once the leach field is <br />constructed, the topsoil will be replaced and the area seeded with the approved seed mix and <br />mulched as soon as ground conditions allow or the following fall. <br />If there is insufficient topsoil available for site reclamation, topsoil will be purchased to make up <br />any topsoil deficit. <br />The attached soil survey shows soil unit 6102A with available soils to 22 inches, gravelly sandy <br />loam. Unit 7702B has soil suitable for site reclamation, 0 -5 inches sandy loam. The other on -site <br />soil units (7700B and 7755B) are too shallow and rocky to be recoverable (0 -2 inches cobbly silt <br />loam). These are high mountain soils in an area of non -acid host rock. <br />There are no other changes to the existing and approved permit. <br />(ii) State at what point in the mining plan the site will be seeded. <br />Explain how the seedbed will be prepared to eliminate compacted <br />conditions. State the type, application rate, and soil incorporation <br />methods of fertilizer application, if any: <br />No site reclamation will begin (other than leach field reclamation) until the underground mining <br />activity is complete. Once site reclamation begins, the mine operational buildings and structures <br />may be removed, to include the Caribou office /shower building, snow roof, fuel tanks, the new <br />office /dry facility, and Cross ore storage shed. (The new sewer line and leach field will be left as <br />constructed) These structures will be dismantled and removed from the site at the cessation of <br />mining operations and before the grounds are graded to final contour and plant growth material <br />replaced. All materials resulting from structure demolition will be hauled to an approved landfill <br />for disposal. All remaining explosives will be disposed according to regulation and approved <br />methods. Any remaining fuels, lubricants, toxic substances (if any) will be disposed in approved <br />facilities. Any concrete foundations and paved areas will be broken up and buried on site. <br />(Calais reserves the right to retain facilities and structures as part of the post mining land use at <br />the request of the landowner. If facilities and structures are left as part of the post mining land <br />use, they will meet Boulder County building and zoning codes.) <br />The remaining disturbances, including the Cross and Caribou surface parking areas, will be <br />ripped and scarified as needed, recontoured, as necessary, for drainage control, and integrated <br />into the surrounding undisturbed topography, then have a plant growth medium replaced. The <br />road will be left for the post mining land use, at the request of the land owner. (Calais reserves <br />the right to retain all or some of the parking areas at the request of the land owner.) <br />If buildings, facilities and parking area are removed, the ground surfaces will be reclaimed to <br />meet the post - mining land use goal of forest land and residential. The area will be graded to <br />Page 32 <br />
