_ . -13- MINING PLAN EXlIIIIIT C Mining operations shall Ue a simple remov;il process in a dry alluvial setting of moderate to gently slopping surface topography wherein [he gravel and sand to be removed is found at the surface and continues downward for the full depth of tlic mining operations. Prom 12" to 3G" of top soil shall be removed and stockpiled for reclamation purposes on the eastern boundary of the pit. As conditions require, tt~e mined substances will Ue pushed into the pit by bulldozers worlang outward from the centcr,of an existing pit, or front-end loaders ~.aill remove materials directly from the pit walls at the bottom of the pit. idherc remova.i can be effected by the first method, sufficient slope will be maintained aC all times to permit the movement of equipment' from ground level to the floor of tl~e pit in the area of operations. lJherc removal from the bottom is required, sufficient slope will be maintained to provide latteral and subjacent support. These procedures will result in a gradual expanding of the boundaries of the pit until the boundaries of the affected area have been reached. Once gravel has been moved to or removed from the bottom of tl:e pit, bulldozers will be used to consolidate the mined materials into stockpiles. Prom this point, front-end loaders will be used to load the mined materials into dump trucks fcr removal Irom the mining area. The mine will first be opened on the northern end of the permitted area. As operations continue southward the northern area shall be reclaimed. Commencement date will be from the approval date to a time when the gravel is exhausted, at wl~icli time we will immediately start on reclamation. Water will not be used in conjunction with this operation. No ground water will be disturbed. P7o crushing, screening, washing, or mixing will be taking place aC the location. Stockpiles will be on East and West boundaries as shown on maps, Exhibit C S E.
