<br />Mr. Wiliam C. Thrailkill <br />u <br />-2- <br />August 30, 1984 <br />3. Rather than planting the topsoil stockpiles with a mix of Yellow <br />sweetclover and an annual small grain, I suggest that the Yellow sweetclover <br />be mixed with a perennial grass from your revegetation mixture and used to <br />stabilize the topsoil stockpiles. Atypical mixture might be 0.5 lbs. <br />PLS/acre of Yellow sweetclover and 14 lbs. PLS/acre at Western wheatgrass <br />(drilled rates}. <br />4. What is the estimated life of the mining operation? <br />\ 5. What is the estimated depth of mining on the site? <br />6. The Soil Conservation Service mentions that some of the eastern part of <br />`the planned pit area is now under water. How is this area to be mined dry (as <br />~ you have described) if water is flowing into the pit? <br />7. Will processing (crushing, screening, etc.) of product occur on site? <br />fit does occur, where will the processing area be located? <br />Exhibit D <br />1. Wildlife: Before the Board can approve this application, our Division <br />must receive an analysis of the effects of the operation on wildlife on the <br />site. Typically, this is produced by the local representative of the Colorado <br />Division of Wildlife. We do not, as a matter of Division policy, submit a <br />request for this information to the Division of Wildlife. Rather, the <br />operator supplies details of the proposed mining operation to the Division of <br />Wildlife, and their personnel produce an evaluation of the site for submittal <br />to our Division. I suggest that you begin this procedure immediately. If <br />necessary, you can use a copy of this letter as authorization to the Division <br />of Wildlife for the need for this evaluation. <br />2. Water Resources: I am still somewhat confused as to the conditions of <br />surface and ground water on the proposed permit area. Are the existing old <br />depressions filled with surface runoff water or water from an adjacent ditch <br />on a year-round basis or only sporadically? Is this a controlled situation in <br />some sense? <br />Exhibit E <br />1. Will there be enough topsoil available on site to supply the i2 to 18 <br />inch replacement depth suggested by the Soil Conservation Service? If not, to <br />what depth will topsoil be replaced? <br />2. Please elaborate further on the status of the recharge pond as part of <br />\ final reclamation. Will this pond be a permanent fixture, or will it only <br />` exist sporadically when water is diverted into it for well recharge purposes? <br />Where will the expected waterline be, and how far will revegetation extend <br />down the planned banks? <br />~3. How is the haul road to be reclaimed? <br />
