' The borrow pit area south of the river will disturb a total of approximately 30 <br /> acres, including approximately 28 acres of excavation, and will be excavated for <br /> ' fill in one phase (South Borrow Pit Area). The excavation area includes <br /> approximately 12 acres of ground previously excavated by a former owner. This <br /> ' area has no pre-determined term of duration, as fill will be excavated and <br /> removed when demand requires it. <br /> Mining Methodology: <br /> North Mining Area <br /> ' After the topsoil/overburden of each approximately two-acre area to be mined in <br /> a one year time period is removed and stockpiled for reclamation, the area will be <br /> mined using a dragline to excavate raw aggregate that,will be window d <br /> adjacent to the actively mined pit. Topsoillov�rburden averages 2.5 ft. in depth <br /> ' over the area to be disturbed by mining activities. The excavation will be <br /> performed in the naturally occurring groundwater table with no de-watering of the/ c <br /> pit area. Mining of the resource adjacent to pit edges will leave slopes of 3:1 and <br /> ' 2:1 leading underwater to the base of the excavation, rather than mining to the <br /> near-vertical and backfilling with overburden or washed fines. The depth of the <br /> ' mineable portion of the deposit averages 36 ft., with greater depths existing <br /> further from the river. Mining will progress in each Phase as shown in Exhibit C. <br /> ' At anticipated sales and onsite utilization of aggregate to total approximately <br /> 50,000 tons per year, this area could take over 100 years to be completely mined <br /> and reclaimed. Reclamation will be concurrent with mining. <br /> ' 12 <br />
