EXHIBIT D MINING PLAN (CONT) include but is not limited to conveyors, crushers and screen plants . A scale and scale house shall be used at the mine during its life. As much as possible, the surface drainage will be maintained in the same direction as it now exists . The proposed sloping plan for the excavated area should eliminate any concerns of erosion occurring from the site . Most of the water used on site will be for dust control used on haul roads or with sand and gravel processing. Please refer to EXHIBIT G WATER for the discussion of how water will be used at the site, the estimated yearly needs and the source of said water. The 2 large irrigation ditches that cross the site and the Cannon return flow ditch will not be impacted by the mining operation. All interior pit slopes will be maintained with a pit ward attitude so that historic drainage patterns can be maintained. This same slope management plan will prevent any offsite slides or other disruptions . Isolation berms or ditches will be constructed around the mine as needed to prevent stormwater from contacting the disturbed areas . All stormwater contacting the disturbed area will be retained on site and allowed to evaporate or soak into the underlying gravel . No U. S . Army Corps of Engineers, 404 permit is necessary, as mining will not impact waters of the U.S. While there are ditches and a non determined wetland area between them, these areas will not be disturbed by mining or reclamation. MINING TIME TA BL E.V This estimated mining timetable is based on an average year, and L.G. Everist expects some years to vary widely from the average. If there are changes in the mining timetable, we will discuss the reasons for the change in the annual report that follows the change and modify it at that time if needed.
