1~~. ~7, l ~~ q ~ <br />Minino Plan <br />The material to be mined is of various quality sand and gravel. For <br />this reason, the progression of the mine is based on the demand for <br />a particular commodity at a given time. <br />Prior to extraction of the material to 6e sold, all topsoil and subsoil <br />suitable as a growth medium will be stripped by a scrapper and stockpiled <br />on site. The topsoil and subsoil is to be segregated and stockpiled <br />separately. The depth of topsoil ranges from 0"-18". The depth of sub- <br />soil or overburden ranges from 18" to 10 feet. The depth of the gravel <br />is from 9-20 feet. Currently materiai is stockpiled on the site which <br />includes a stockpile containing approximately 25,000 cubic yards of top- <br />soil. <br />The amount of area affected by mining has averaged 1 to 2 acres per year. <br />Equipment to be used in the mining operation includes a scrapper, loader, <br />D-8 cut, and, as needed, a portable crushing and screening plant. <br />II. Reclamation <br />The timetable for the area to be mined is such that a given area will be <br />mined for its particular value when there is a market demand. However, <br />once extraction of material has been completed, the area will be regraded, <br />retopsoiled, and reseeded within one growing season of the completion of <br />mining. <br />Post mining contours will not exceed 3:1 slopes. The area will be retop- <br />soiled with 6" - 12" of salvaged topsoil. The operator intends to use <br />manure as an amendment to the soil. The manure will be disced into the <br />soil. At the time of reclamation if it is determined that soil amendments <br />such as phosphorous or nitrogen need to be added, they will be added. Also, <br />after the seed has been drilled, straw mulch will be used if it is deemed <br />necessary. <br />The area is to be grazed after reclamation, however, grazing will not be <br />allowed until the Mined Land Reclamation Board and the Soil Conservation Scrvict <br />have been consulted and approve a grazing program. This means reclaimed <br />areas will need to be fenced to prevent grazing. <br />The seed mix is: Western Wheatgrass 3 ib. P.L.S./Acre <br />Side Oats Gramma 5 lb.
