<br />(a) Please provide a more detailed description of the mining methods that will be employed [o extract <br />clay from this site. Tltis should include a general schematic diagram for each phase showing the <br />mining direction, the location of overburden, product and topsoil stockpiles, dimensions of the <br />proposed disturbances within each phase, etc. Also, [he application makes reference to "phases" <br />(1-4) and the map shows "areas" (A-H). Please explain how these hvo terms are related and <br />include both terms on the map and in the text of the application, orjust utilize one term to describe <br />the mining units. <br />(c) Under this section (water diversions and impoundments) the application indicates that no surface <br />or subsurface water rights will be affected during the mining operation, however, surface runoff <br />may be affected during precipitation events since disturbed area drainage will be mixed with <br />undisturbed surface area drainage, thereby, creating the potential for excessive erosion and <br />sedimentation to occur. The operator may want to install upland diversions to divert surface <br />runoff away from the disturbed areas, and/or install sediment traps below the disturbed areas to <br />capture any excess sediment that could be carried away during heavy precipitation events. Please <br />describe how the surface water will be managed to prevent excessive erosion and sedimentation. <br />(f) Please identify on the mining plan map where the topsoil stockpiles that will be used during <br />reclamation will be located. <br />6.4.5 EXHIBTT E- Reclamation Plan <br />The reclamation plan that is included in this application is substantially adequate. Based upon the pre- <br />operational inspection and [he CDOW report included with the application, it was noted that a majority of <br />the site is wooded or partially wooded. However, the seed mix does not include any woody species and <br />the reclamation plan does not call for replacing any woody vegetation. It was suggested during the <br />inspection that some woody species should be included in the seed mix and the CDOW report also <br />suggests using woody species in the seed mix. In addition, the suggestion by the BLM to use the trees and <br />woody plants that are removed in advance of mining as slash over the reclaimed areas is a good one. <br />These plants will provide a potential seed source as well as protection for small seedlings. Please revise <br />the existing seed mix to include at least one woody species and one or two desirable fortis. <br />6.4.6 EXIIIBIT F- Reclamation Plan Mao <br />This section is adequate as submitted. <br />6.4.7 EXHIBIT G- Water Information <br />As noted before, surface runoff could present a slight problem with respect to off-site sedimentation. <br />Please identify measures that will be taken to minimize erosion and potential off-site damage. <br />6.4.8 EXHIBIT H- Wildlife Information <br />No comment. <br />
