Exhibit D (Cont) <br /> Mining Plan <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 off site stormwater from <br /> contacting the disturbed area. All stormwater contacting the <br /> disturbed area will be retained on-site and allowed to evaporate <br /> or soak into the underlying gravel . No U.S . Army Corps of <br /> Engineers 404 permit is necessary, as there are no jurisdictional <br /> water bodies on the site nor are there any wetland areas that <br /> will be disturbed by mining or reclamation. EXHIBITG-WATER contains <br /> a letter from the Corps for your review. <br /> MINING TIMETABLE <br /> This estimated mining timetable is based on an average year <br /> and Colorado Backhoe Service expects a specific year to vary <br /> 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 /> ACRES + <br /> ESTIMATED TOTAL TOTAL MINED MINED <br /> YEARS AREA MINED 100% SLOPES <br /> 8-10 25 . 12 10 . 67 8 . 57 2 . 10 <br /> 12 <br />
