/~l <br />O <br />O , <br />14 r. Gilbert F. Rindahl -I_- March 21, I~Jil3 <br />3. An examination of the mininy plan map and the reclamation plan map <br />shows the topsoil beans to lie in an area that will be sloped in <br />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 duriny 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 />~~~. of the drainaye to the west of the mininy area should he shown on the <br />p ,~ <br />~; map. <br />~.~- <br />y;6. Are gravel stockpiles to be maintained in the plant area? <br />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 7-y" or 8-12" of <br />topsoil being replaced. Why uoes this rather larye 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 maxi~nu~n 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 enouyh to not <br />require blastiny fur removal. Please clarify this matter and detail <br />y, tl~e 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 u~t, or will terracing <br />' be used during the mining operation? <br />~~~~~ 6. What material underlies the material to be mined? <br />\7. Is the trianyular area to the southeast of Vollmer Road to be used in <br />' the mininy operation? <br />8. Will all access to the pit be via tl+e haul road to 131ack Forest Road, <br />'` or will there be an access to Vollmer Road, as well? <br />
