• -4- • MINING PLAN EXHIBIT D Mining operations shall be a simple removal process in a dry alluvial setting of moderate to gently slopping surface topography wherein the gravel and sand to be removed is found at the surface and continues downward for the full depth of the mining operations. From 12" to 36" of top soil shall be removed and stockpiled for reclamation purposes on the eastern boundary of the pit. As conditions require, the mined substances will be pushed into the pit by bulldozers working outward from the center of an existing pit, or front-end loaders will remove materials directly from the pit walls at the bottom of the pit. Wh~are removal can be effected by the first method, sufficient slope will be maintained at all times to permit the movement of equipment from ground level to the floor of the pit in the area of operations. Where 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 boundari~=_s 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 the pit, bulldozers will be used to consolidate the mined materials into stockpiles. From this point, front-end loaders will be used to load the mined materials into dump trucks for removal from 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 which time we will immediately start on reclamation. Water wi.Ll not be used in conjunction with this operation. No ground water will be disturbed. No crushing, screening, washing, or mixing will be taking place at the location. Stockpil~zs will be on East and West boundaries as shown on maps, Exhibit C & E.
