6.33 Exbibit C-Mining Plan <br />6.3.3 (a) <br />The proposed starting date to start this pit will be May 2007 and the ending date is <br />expected to be May 2017 due to the amount of materials located at the site. <br />6.3.3 (b) <br />The estimated depth to which the soil is suitable as plant growth medium is <br />approximately 12 to 49 inches. There will be enough plant growth medium stored to <br />reclaim the site. Once the pit is exhausted, there will be a minimum of 12-15 inches <br />cover of plant growth medium placed over the reclaimed azea. There will be a limited <br />sale of "top soil". <br />The pit will be stripped of the available topsoil by loaders. The top soil will be stored in <br />the Western and Southern corner of the 9.98 acre site as depicted on the Mine Plan Map, <br />Exhibit E until it is needed for reclamation. This location keeps the topsoil out of the <br />way of mine traffic and waterways. <br />The stockpiles will be seeded to reduce soil erosion. The operator will keep the topsoil <br />free of any contaminates, which would cause toxic or acid-forming materials. <br />6.33 (c) <br />It is estimated that the thickness of the overburden to the deposit to be mined will vary <br />from one foot to ten feet. The overburden will be stored in the Western portion of the pit. <br />6.3.3 (d) <br />The thickness of the deposit to be mined will vary from six feet deep to thirteen feet deep. <br />The data result from the Harkin Report (a copy is enclosed in the original submission) <br />found the groundwater depth to be between ten and eighteen feet. The applicant is <br />committed not to interfere with ground water in anyway by not excavating deeper than <br />the groundwater level (which varies from 10-18 feet) and allowing for a substantial gap <br />between the groundwater level and the depth of excavation. The operator will adjust the <br />depth of excavation, as he gets closer to Hazdscrabble Creek, to avoid exposing <br />groundwater. The applicant understands that if ground water is exposed, the operation <br />must cease immediately and the applicant must seek remedial action through a substitute <br />water plan or augmentation plan. <br />On 3/26/07 three test holes were dug on the site down to a depth of approximately 17 <br />feet. The Fremont County Engineer was on-site to determine if groundwater was <br />exposed. Groundwater was not found at this depth. <br />6.3.3 (e) <br />
