vim, o~ ~~ / 7 ~' • I. Mining Plan 111 lllllllllllll lfl The material to be mined is of various quality sand and gravel. For this reason, the progression of the mine is based on the demand for a particular commodity at a given time. Prior to extraction of the material to be sold, ail topsoil and subsoil suitable as a growth medium will be stripped by a scrapper and stockpiled on site. The topsoil and subsoil is to be segregated and 'stockpiled separately. The depth of topsoil ranges from 0"-18". The depth of sub- soil or overburden ranges from 18" to 10 feet. The depth of the gravel is from 9-20 feet. Currently material is stockpiled on the site whieh includes a stockpile containing approximately 25,000 cubic yards of top- soil. The amount of area affected by mining has averaged I to 2 acres per year. Equipment to be used in the mining operation includes a scrapper, loader, D-8 cut, and, as needed, a portable crushing and screening plant. II. Reclamation The timetable for the area to be mined is such that a given area will be mined for its particular value when there is a market demand. However, once extraction of material has been completed, the area will be regraded, retopsoiled, and reseeded within one growing season of the completion of mining. Post mining contours will not exceed 3:1 slopes. The area will be retop- soiled with 6" - 12" of salvaged .topsoil. The operator intends to use manure as an amendment to the soil. The manure wilt be disced into the soil. At the time of reclamation if it is determined that soil amendments such as phosphorous or nitrogen need to 6e added, they will be added. Also, after the seed has been drilled, straw mulch will be used if it is deemed necessary. The. area is to be grazed after reclamation, however, grazing will noL be allowed until 'the Mined Land Reclamation Board and the Soil Conservation Scr~ice have been consulted and approve a grazing grogram. This means reclaimed areas will need to be fenced~to prevent grazing. The seed mix is: Western Wheatgrass 3 lb. P.L.S_/Acre Side Oats'Gramma 5 lb. P.L.S./Acre Blue Gramm ;5 lb.
