der of the area will be stored in the 6.0 acres that has been mined out, In this way, a large amount of <br />overburden does not need to be initially stored out of the pit area. The total soil/overburden from <br />the area is 29.78 acres x 5.8 ft = 278,000 cy. Topsoil and overburden will Likely be moved with <br />scrapers, however, it is possible that trucks and loaders may also be used. Mining will be conducted <br />with front end loaders and dozers. A portable processing plant will be located in each pit and trucks <br />will be used to haul the processed material from the pit to the staging area located in the northwest <br />corner of the permit area. Al] fines from processing will be sold, therefore, no naturals or fines will <br />be available for backfi[ling in the excavated areas. <br />The overburden from the 6.0 acres @ 4.75 feet is 45,960 cy. This amount will be stored in the 2 <br />adjacent overburden stockpiles shown on Map C-2. These stockpiles are 1.92 acres in combined <br />size and will have an average height of 10 feet, therefore, they will store 30,976 cubic yards. This <br />leaves 14,984 cy to be stored within Mining Area 1 adjacent to the initial 6.0 acres of excavation. <br />The 6.0 acre area will be mined to a slope of 2.OH1.OV to an average depth of 23.8 feet, as shown <br />in the above table. Once the initia16.0 acres is mined out, the 14,984 cy will be moved into the <br />mined area to backfill the slopes to 3H:1V. This will expose the remainder of the gravel within <br />Mining Area 1 and make it ready for mining. The gravel will then be mined from the rest of Area 1 <br />while groundwater is being pumped to the sediment pond. It is expected that groundwater will be <br />encountered within 4-5 feet of the surface on all lower bench areas (Mining Areas 1,2 and 3). <br />Topsoil and overburden stripping will then take place in Area 2. The table below shows the drill <br />data and average thicknesses for Area 2: <br />Area 2 <br />Hole # Soil/Overburden <br />Depth Gravel Thickness Total Depth <br />29 5.0 20.5 25.5 <br />40 3.5 21.0 24.5 <br />41 0.5 24.0 24.5 <br />42 5.0 19.0 24.0 <br />15 Road Pit 10/02 9 <br />
