i <br /> The approximate timetable for the mining amendment will be totally market dependent. <br /> There are approximately 2,400,000 tons of material on-site. The average yearly sales for <br /> the operation will range between 125,000 to 250,000 tons per year. Based on these <br /> estimates, the following schedule is estimated: <br /> Description Mining Period Reclamation Period <br /> PHASE 1 1993-1998 1995-2000 <br /> PHASE 2 1998-2013 2000-2015 <br /> One lake will be created by the mining operation. This lake will have a surface area of <br /> approximately 29 acres. <br /> The sequence of mining activities to be done is as follows: <br /> 1. A dewatering ditch will be constructed around the perimeter of the phase. <br /> 2. A dewatering pump will be installed and groundwater will be discharged to the <br /> settling ponds on the north side of the pit. <br /> 3. Any topsoil or overburden encountered will be stripped and the amount needed for <br /> reclamation will be :stockpiled. <br /> 4. Sand and gravel will be extracted and transported to the plant for stockpiling. <br /> 5. Material may be processed (or not) and will be trucked from the property to end <br /> users. <br /> The overall mining plan calls for completion in approximately 20 years, Phase 1 taking <br /> five years to complete and Phase 2 taking 15 years to complete. Each phase will be <br /> divided into stages consisting of approximately three acres. Mining and reclamation of <br /> each stage will be done concurrently. <br /> When mining is completed in one stage and moves to the next stage, reclamation <br /> activities will begin immediately on the completed stage. Grading and backsloping of <br /> shorelines will be done using concurrently stripped material or stockpiled topsoil and <br /> overburden. Reseeding will be done in early spring or late fall depending on the progress <br /> of regrading. Provisions have been made to return the following year and reseed areas <br /> where previous reclamation was not successful. The estimated time between completion <br /> of a mining stage and accomplishing final reclamation of that stage is five years. <br /> D-3 <br />
