4. The seeding operation shall be by drilling when possible (but will more likely be <br />broadcast due to steep rocky slopes) with a drill spacing of 8-12 inches and a planting <br />depth of 1/4 to %2 inch. As stated above in 2, 2 -ton straw mulch/acre and weed control <br />will be surface material available at the site. Final slopes in unconsolidated material <br />graded to no steeper than 2:1. Steeper slopes in competent bedrock may be steeper <br />but should blend with the natural terrain and must be stable. All level areas and <br />graded slopes to be seeded and vegetated. The adjacent .62 acres will have top soil <br />removed and piled up. The area will be ripped and top soil will be redistributed and <br />drilled. No shrub or tree species will be planted at the site. Seeding of stockpiled topsoil <br />for stabilization will be broadcast and raked by hand using the same recommended seed <br />mix as above. Recommended seedbed preparation date is late June with July 1-15 <br />recommended for seeding. <br />(d) There will be no ponds, streams or other impoundments constructed as part of <br />reclamation activities. The future use of the site is planned as rangeland/wildlife habitat. <br />All permanent man-made structures shown on the Exhibit E and Exhibit L Maps will <br />remain. <br />(e) There will be no waste rock dumps, underground openings, plant facilities constructed <br />or used during the mining activities and as such no reclamation treatment is necessary <br />for these items. Storage shed on the mine site will be removed for reclamation. <br />Stormwater control features such as berms ditches and silt fences will be used as part of <br />the active mining activities. Silt fencing will be removed prior to the final grade <br />operation of reclamation and disposed of offsite. Berms, ditches and haul roads will be <br />incorporated into the final grade prior to topsoil application. The final grade as possible <br />at such a vertically outcropping site will have a general slope of 2:1 max in <br />unconsolidated material. It is not planned to completely mine the entire proposed 8.14 <br />acres. Activities will disturb approximately 3 acres total. Since large boulders and rock <br />may be lifted from the surface anywhere in the 8.14 acres (if desired and accessible). <br />(f) <br />Reclamation Costs: After a period of 20 years the site will have reached a point of <br />approximately 3 acres maximum disturbance. Generally, by the date, lower slopes will <br />have already been graded up to a final high -wall location and final reclamation activities <br />will commence. It is estimated that a total of one week will required for the final <br />reclamation of the site. Most reclamation at the site will be scaling the high -wall and re- <br />grading the flatter operations area and lower slopes (and less), remove and incorporate <br />any sediment berms and ditches, and provide a final grade and place surface <br />material/topsoil. An additional 2 days is estimated for seedbed preparation and <br />seeding. Rock scaling may take a single day as most weathered rock would have been <br />removed already down to the competent bedrock via the mining. <br />
