6.4.3 EXHIBIT C - Pre-mining and Mining Plan Map(s) of Affected Lands <br />1.) This map must be signed by the registered land surveyor, professional engineer or <br />qualified person who prepared it. <br />2.) The note listed on the map states, "The orientation of the final 3:1 slope is a <br />maximum slope limit, and may vary depending on the life of the operation." Please <br />clarify, will any slopes be reclaimed steeper than a 3:1 horizontal to vertical ratio? <br />3.) Are the blue lines depicted on the map contour lines? If so, please label the various <br />elevations and indicate the contour interval. <br />4.) Exhibit G indicates a berm will be built on the north and east side of the permit area <br />to control run off from leaving the mine area. Please depict this berm on the map. <br />6.4.4 EXHIBIT D - Mining Plan <br />5.) The mining plan indicates an asphalt and concrete batch plant will be used within the <br />permit area to process the mined material. Please explain how the surface and ground <br />water system will be protected during processing of the mined material? <br />6.) Will the asphalt and concrete batch plant be portable/moveable? If not, please <br />indicate the dimensions of these structures, such as length, width and height. Will a <br />cement foundation be constructed for these units? If so, what will be their dimensions <br />(length, width and depth)? <br />7.) Exhibit L indicates a highwall will be created during the mining operation. What will <br />be the maximum length of the highwall at any given time during the operation and what <br />will be the slope? <br />8.) Exhibit G indicates a berm will be built on the north and east sides of the permit area <br />to control run off from leaving the mine area. Please indicate the dimensions of this <br />berm. <br />9.) Will topsoil and overburden be removed from the "Stock Pile Area" indicated on the <br />Exhibit C maps? <br />6.4.5 EXHIBIT E - Reclamation Plan <br />10.) Item 2f (iv) states there will be no re-vegetation. However, the designated post <br />mine land use is rangeland and item 2f(ii) states reseeding will be done per the seed mix <br />recommended by the NRCS. The Operator is obligated to establish diverse and self- <br />sustaining vegetation throughout the site prior to full site release. Please commit to re- <br />vegetating the site.
