6. Explain the design of the mining phases and blocks in terms of size and mine <br />progression. Do the size of the blocks relate to annual production? Give rationale for <br />mining eastern portion first, then western side in final phases. <br />7. The mine plan narrative should state that the visual and safety buffer zones define the <br />limit of mining. <br />8. The reclamation tables show direct topsoil replacement into the previous mined-out <br />block in order to accomplish ongoing reclamation. Explain how overburden will be <br />handled as part of the procedure. Will topsoil be snipped and temporarily stockpiled in <br />order to strip overburden for direct placement into mined-out area, then pick up the <br />topaoil again for spreading over the rewntoured overburden? <br />9. Address fencing of the site, security gate, and safety mitigation as related to recreation <br />users and gun range activities. <br />] 0. Submit a smaller scale map (such as 1" = 200') that shows the mine plan layout, <br />topogaphy, gun range site, haul road route, scales, security gate, etc. <br />11. Dust control is briefly mentioned for haul mad and topsoil berms, but needs <br />expanded to describe dust control measuresused during stripping, mining, crushing, <br />stockpiling, loading and haulage. <br />12. What is the capacity of haulage tracks? <br />Please submit your response to the above items by January 20, 2006. The information is <br />needed in order to complete the environmental assessment (EA) on.the project. If you <br />have any questions or would like to discuss these items further, pease contact Bruce <br />Fowler at 244-3036. <br />Sincerely, A <br />~I~J <br />~2'Catherine Robertson <br />' Field Manager <br />Cc: Jim Komatinsky, Mesa County Planning <br />Russ Means, DMG <br />Bob Engelke <br />Walt Eldridge <br />
