The following comments and answers to the adequacy review are found below: <br />I) Exhibits "A", `B", & "C"- No Comment. <br />II) Exhibit "D° Mining Plan <br />A} The Blue Dashed Line shown on all the maps submitted depicting the Special <br />Use Pemit Boundary (SUP) is indeed the same as the Boundary depicting the <br />112 c Division of Reclamation, Mining and Safety (DBMS) Permit Boundary. It <br />was a mistake on the drawings that should have been corrected. However it is the <br />same and the operator commits to this as the official 112c Boundary. <br />B) As you apply point out the total phased acres add up to 164 acres leaving <br />16 acres unaccounted for in the Pemritted area Enclosed is a revised Mining Plan <br />Map, which now shows the areas, not included before on the original maps. <br />Please see the revised Mining Plan Map that now shows the areas in question <br />crosshatch and added to the phased area total acreage in the Estimated Mining <br />Timetable. The areas shown will be used for stockpiles or haul roads to facilitate <br />miring and transportation. <br />C) This mine site is projected to be in operation until the year 2040, in <br />the futwe it might be advantageous to consider using portable overland <br />conveyors to transport the materials to the process azea. The conveyors that <br />would be utilized do not need powed in place concrete foundations therefore no <br />extra cost to remove them should be related to the reclamation. <br />D) Item 6.4.4 (b) Exhibit "D" states that "all earth moving will be done <br />with equipmenti suitable for this type of operation including the following types: <br />crawler dozer, wheel loaders, earthmoving scrapers, excavator, dragline, and haul <br />tracks of various sizes up to and including units with a 20 ton capacity." The <br />dragline is only' one option that could be used to strip the overbwden if is ever <br />needed, this would only occw if the overbwden seam became very thick which is <br />unlikely on this site. There is no need excavate any deeper than 18 to 20 feet <br />
