4. The seeding operation shall be by drilling when possible (but will more likely be broadcast <br />due to steep rocky slopes) with a drill spacing of 8 - 12 inches and a planting depth of/e to <br />'/z inch, As stated above in 2, 2-ton straw mulch/acre and weed control will be as <br />necessary. Seedbeds will be firm and clean tilled as possible with the limited rocky <br />surface material available at the site. Final slopes in unconsolidated material graded to <br />no steeper than 2:1. Steeper slopes in competent bedrock may be steeper but should <br />blend-in with the natural terrain and must be stable. All level areas and graded slopes <br />to be seeded and vegetated. No shrub or tree species will be planted at the site. Seeding of <br />stockpiled topsoil for stabilization will be broadcast and raked by hand using the same <br />recommended seed mix as above. Recommended seedbed preparation date is Tate June with <br />July 1 [o I S recommended for seeding. <br />(d} There will be no ponds, streams or other impoundments cons[mcted as part of reclamation <br />activities. The future use of the site is planned as rangeland/wildlife habitat. All permanent <br />man-made structures shown on the Exhibit E and Exhibit L Maps will remain. <br />(e) There will be no waste rock dumps, underground openings, plant facilities and/or buildings <br />constructed or used during the mining activities and as such no reclamation treatment is <br />necessary for these items. S[ormwater control features such as berms ditches and silt fences <br />will be used as part of active mining activities. Silt fencing will be removed prior to the final <br />grade operation of reclamation and disposed of offsite. Berms, ditches and haul road will be <br />incorporated into the final grade prior to topsoil application. The final grade as possible at <br />such a vertically outcropping site will have a general slope of 2:1 max in unconsolidated <br />material. It is not planned to completely mine the entire proposed 8.14 acres. Activities will <br />disturb approximately 3 acres total. Since lazge boulders are planned to be mined at the site <br />existing single or multiple large boulders and rock may be lifted from the surface anywhere <br />within the 8.14 acres (if desired and accessible). <br />(t) Reclamation Costs: After a period of 20 years the site will have reached a point of <br />approximately 3 acres maximum disturbance. Generally, by that date, lower slopes will have <br />already been graded up to a final high-wall Location and final reclamation activities will <br />commence. It is estimated that a total of one week will be required for the final reclamation <br />of the site. Most reclamation at the site will be scaling the high-wall and re-grading the <br />flatter operations area and lower slopes Approximately 40 hours of bulldozer time will be <br />required [o establish the 2:1 slopes {and less), remove and incorporate any sediment berms <br />and ditches, and provide a final grade and place surface material/topsoil. An additional 2 days <br />is estimated for seedbed preparation and seeding. Rock scaling may take a single day as most <br />weathered rock would have been removed already down to the competent bedrock via the <br />mining. <br />Total reclamation costs are as follows: <br />Bulldozer (D-6 incl. Mob) - 40 hours @ t 25/hour = $5000.00 <br />Tractor (with disc) - 10 hours @ 95/hour = $ 950.00 <br />Tractor (with seed drill) - 10 hours @ 90/hour = $ 900.00 <br />Rock Scaling - I day @800/day = $ 800.00 <br />Seed Mix - 33 PLS for 3 acres = $ 400.00 <br />6 ton Straw Mulch - applied/crimped 250/ton = $ 1500.00 <br />Total estimated reclamation cost = $ 9550.00 <br />This cost estimate includes fuel, mobilization, operator and associated labor. <br />
