<br /> <br />for. Gilbert F. Rindahl -"L- March 21, 1883 <br />3. An examination of the mining plan snap and the reclamation plan snap <br />shows the topsoil beans to lie in an area that will be sloped in <br />Z final reclamation. Since reclamation of phases is to be concurrent <br />with mining, and the topsoil berms are not to be disturbed until the <br />- last phase is reclaimed, please explain this discrepancy between the <br />maps. <br />4. Since the plant area and extraction process are to move from east to <br />west, with reclamation to follow mining, a haul road across the <br />mined-out phases must be maintained during the entire life of the <br />~\ mine, presumably to be reclaimed at the end of mining. This haul <br />road should be shown on the map. <br />5. Any sediment control structures (such as beans) needed for protection <br />~~, 2 X of the drainage to the west of the mining area should be shown on the <br />~;~ map. <br />~ \/6. Are gravel stockpiles to be maintained in the plant area? <br />7 Exhibit U <br />1. I note that 11-14" of topsoil is to be stripped and stockpiled. Yet <br />later statements about reclamation mention either 1-y" or 8-12" of <br />topsoil being replaced. Why noes this rather layye discrepancy exist? <br />2. The amount and classification of mining disturbance types is not <br />clearly defined. Although the plan to move in stages from west to <br />east is clear, the maximum amount of each type of disturbance (major, <br />moderate and minor) is not defined. This makes the reclamation costs <br />(in Exhibit L) difficult to justify. Please provide more detail in <br />this matter. <br />3. Presumably, the material to be mined is weathered enough to not <br />require blastiny For removal. Please clarify this matter and detail <br />the type of equipment to be used in the extraction of the weathered <br />sandstone. <br />~ 4. What will be the working face slope of the active excavation? <br />%5. Will the 25' sandstone layer be mined in one cut, or- will terracing <br />~ be used during the mining operation? <br />,n <br />h -~ 6. What material underlies the material to be mined? <br />•~ <br />~7. Is the triangular area to the southeast of Vollmer Road to be used in <br />the mininy operation? <br />•Y 8. Will all access to the pit be via the haul road to Black Forest Road, <br />'\ or will there be an access to Vollmer Road, as well? <br />
