<br /> <br /> <br /> <br />Mr. William Thurston <br />- 2 - <br />4. Specify the thickness of the deposit to be mined. <br />Octoaer 31, 1986 <br />5. Describe the major components of the mining operation such as: roads and <br />access routes, pit, shop/maintenance, plant, processing and office <br />facilities. These components must be located on Exhibit E - Map. <br />6. Specify the dimensions of any existing or proposed roads that ill be used <br />for the mining operation. Describe any improvements necessary on fisting <br />roads and the specifications to be used in the construction of new roads. New <br />or improved roads must he included as part of the permitted acreag . <br />7. Specify haw much water will be used in conjunction with the op ration, and <br />the source of this water. <br />8. If ground water will be encountered and/or surface water interc pted or <br />disturbed, describe how mining will affect the quantity and quality of the <br />surface or ground water and the methods to be used to minimize dist rbance to <br />the surface and ground water systems including proposed sediment-co tainment <br />systems. <br />9. The crusher location must be shown on Exhibit E. <br />EXHIBIT D - Reclamation Plan <br />1. Specify when the overburden will he replaced in relation to ong ing <br />extraction. We recommend that you consider backfilling and establi hing the <br />final reclaimed grade on previously mined areas at least once per y ar. If <br />you backfill and reduce slopes as soon as practicable, then you wil generally <br />be increasing the efficiency of the operation by minimizing the han ling of <br />overburden, hastening reclamation and release of the financial warr my back <br />to you. <br />2. Specify the maximum gradient of reclaimed slopes (horizontal ertical). <br />We recommend 5:1 or gentler for purposes of stability and revegetat'on <br />establishment. If you propose steeper slopes you should include a <br />justification that supports the proposed post-mining land use and d monstrates <br />compliance with the applicable performance standards of Rule 6. <br />3. Specify any ponds, streams, roads and buildings that will remai after <br />reclamation. These features must be shown on the Exhibit E - Map. <br />4. What are the volumes of overburden and topsoil needed for recla~ation and <br />available on the site? <br />Please provide greater detail on the source of imported overburden. <br />
