MINING PLAN EXHIBIT D (CONT) <br />Processing equipment may include but is not limited to conveyors, <br />crushers and screen plants. A scale and scale house as well as <br />shop and maintenance buildings may also be built at the mine <br />during its life. No blasting will take place at this mine. <br />As much as possible, the surface drainage will be maintained <br />in the same direction as it now exists. The proposed sloping <br />plan for the excavated area should eliminate any concerns of <br />erosion occurring on the site. <br />On a typical operation of this type we may use 2 to 3 ac -ft <br />of water per year. Most of the water used for dust control will <br />be used on haul roads. Please refer to EXHIBIT G - WATER for the <br />discussion of how water will be used at the site and the source <br />of said water. <br />There are no ditches crossing the site and no surface or <br />subsurface water will be impacted by the mining operation. All <br />interior pit slopes will be maintained with a pit -ward attitude <br />so that historic drainage patterns can be maintained. This same <br />slope management plan will prevent any offsite slides or other <br />disruptions. Isolation berms or ditches will be constructed <br />around the active mining area to prevent stormwater from contact- <br />ing the disturbed area. All stormwater contacting the disturbed <br />area will be retained on site and allowed to evaporate or soak in <br />to the underlying gravel. No U.S. Army Corps of Engineers, 404 <br />permit is necessary, as there are no water bodies on the site nor <br />are there any wetland areas. <br />MINING TIMETABLE <br />This estimated mining timetable is based on an average year <br />and Walsenburg Sand and Gravel, CO. expects a specific year to <br />vary widely from the average. If there are changes in the mining <br />timetable we will discuss the reasons for the change in the <br />annual report that follows the change and modify it at that time. <br />ESTIMATED MINING TIMETABLE <br />11 <br />ACRES + <br />OPTION <br />ESTIMATED <br />YEARS <br />TOTAL <br />AREA <br />TOTAL <br />MINED <br />MINED <br />100% <br />MINED <br />SLOPES <br />#1 <br />28 -38 <br />26.73 <br />22.85 <br />17.34 <br />5.51 <br />#2 <br />29 -38 <br />26.73 <br />22.85 <br />18.20 <br />4.65 <br />#3 <br />30 -40 <br />26.73 <br />1 22.85 <br />1 19.51 <br />3.34 <br />11 <br />
