Seeding, Fertilizer, and Mulching Cost Estimates, Site Wide, Life of Mine <br />Native Seed Mix Cost @ 20#/ acre broadcast seeding rate ($17.40/#) <br />$350/acre x 62 acres seeded over life of mine = $21700 <br />Mulch applied at 2000#/acre over 62 acres, $100/acre material, $150/acre labor <br />$250 x 62 acres = $15550 <br />Fertilizer (if necessary) Material and Labor cost estimate: $200/ac Labor & Matl <br />$200 x 62 acres = $12400 <br />Subtotal, Life of Mine Seed, Mulch, Fertilizer Cost Estimate $49650 <br />Highwall Bench Reclamation/Final Configuration Cost Estimate <br />Life of Mine Highwall work will cover approximately 34 acres including ditches, topsoil <br />stockpile areas, mining benches, and rock faces. Final slope configuration will be <br />determined after fast cut of the upper mining bench, but will ultimately range from <br />between 75° and 45° depending upon rock competency evaluation. At any rate, the mine <br />benches will be graded @1% to highwail side and graded to drain to the southern ditch <br />system which diverts all snow melt and rain event to the lower pit area. All mine benches <br />will have a 3' high minimum berm left app. 8' from highwall to catch debris from the <br />highwall face and a small berm 1' high at the outside edge of the flat bench to minimize <br />run-off over the highwall face. Highwall bench reclamation plans include removal of <br />loose or unstable rock as needed, capping flat bench tops with 1" of topsoil, grading, <br />berm and ditch construction, seeding, and mulching (costs covered under above estimate) <br />A gross estimate of highwall reclamation cost in addition to those already estimated <br />under topsoil placement and seeding, fertilizer, and mulching estimates is $1000/acre, <br />based on estimates of excavator and bulldozer hours necessary to complete stabilization <br />and ditch work. 34 acres @ $1000/acre $34000 <br />Subtotal, Life of Mine Cost Estimate for Highwall Reclamation Machine Work <br />................................................................................................... $34000 <br />Other Direct Costs <br />One Acre Staging Area (900' from CR228&USHighway 511) ........................ $2000 <br />One acre road cnt backfdling, topsoiling, and seeding ................................ $3500 <br />(outside of proposed affected land boundary) <br />Mobilization/Demobilization ............................................................... $5000 <br />26 <br />
