Use D-8 w/universal blade. Cost is $0.52/cy. <br />2 Rip to a depth of 2.0 feet all azeas prior to 4 $5,643 <br /> topsoiling. Cost = $250/acre for 22.57 acres <br />3 Spread topsoil on reclaimed azea from stockpile 11 $8,060 <br /> 22.57 acres @ 6 inches average thickness (15500 <br /> cy). Use D-8 w/universal blade. Cost is $0.52/cy. <br />4 Spread topsoil on reclaimed azea from topsoil 12 $9,100 <br /> berms azound the perimeter of [he mine. (17500 <br /> cy). Use D-8 w/universal blade. Cost is $0.52/cy. <br />5 Final grading and harrowing of topsoil, upper zone 19 $5,890 <br /> only, (15500 cy @ $0.38/cy). <br />6 Seed, mulch, fertilize (22.57 acres@ $700/acre) 4 $15,800 <br /> Drill seed on flat areas. Mulch at 1.5 tons per acre <br /> on rangeland azeas. <br /> Total Direct Costs 122 days $105,333 <br /> DMG Costs (19.5% x direct costs) $20,540 <br /> Total Bond Amount $125,873 <br />3. Revegetation Plan <br />There will be two revegetation seed mixes which will need to be applied to the reclaimed Halodorson <br />Sand and Gravel Mine. The seed mix which will be applied to the slopes of the pit as well as the flat <br />areas on the perimeter of the pit will use the seed mix shown below in Table E-4. This seed mix was <br />developed based on apost-mining use of dry rangeland. It should be more than adequate to control <br />erosion for the site and provide good cover. The second seed mix which will be applied to the flatter <br />bottom of the pit will be the same irrigated crop which were growing on the land previous to mining. <br />Haldorson Sand and Gravel Mine 27 <br />
