6.) Will the asphalt and concrete batch plant be protable/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 />A: The asphalt and concrete plants are portable and moveable. <br />7.) Exhibit L Indicated a highwall will be created during the mining operation. What <br />will be the maximum length of the highwall at any given time during the operation and <br />what will be the slope? <br />A: The maximum length is 1500 feet and 40 foot high and will be vertical slopes <br />during mining. <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 />A: The berm will be constructed approximately 2' to 6' high using existing <br />strippings of topsoil. <br />9.) Will topsoil and overburden be removed from the "Stock Pile Area" indicated on the <br />Exhibit C maps? <br />A: Yes - topsoil and any overburden will be removed and stockpiled in the berm. <br />10.) Item 2f(iv) states there will be no re-vegetation. However, the designated post mine <br />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 <br />revegetating the site. <br />A: We will comply with the NRCS seed recommendation for seeding and we will <br />not be using mulch. There will be no tree or shrub planting. <br />11.) Will a sterile/non-competitive covercrop of sorghum-sudangrass be established at <br />the site to aid native grass establishment as recommended by the NRCS in the paragraph <br />below the seed mixture? The Division recommendsd following the NRCS <br />recommendation. Or, will mulch be used at the site? If so, what type will be used and <br />how many tons per acre will be applied. <br />A: We will follow NRCS recommendation. No mulch will be used. <br />12.) Will the perimeter side slopes be graded to a 3:1 horizontal to vertical ratio in Phase <br />A of the mining operation prior to mining phase B? Concurrent reclamation of the <br />perimeter slopes will likely lower the financial warranty amount.
