MINING PLAN EXHIBIT C <br />1. General Plan <br />The general plan is [o mine gravel from a 7.5 acre area in two phases: one 5 month period in the <br />winter of 2002-2003 and one 5 month period in the winter of 2003-2004. A total of 255,000 tons of <br />gravel will be removed from the site. Reclamation will proceed as the site is mined. <br />The property boundaries has been surveyed on site and the permit area will be surveyed prior to any <br />site disturbance. Map E-1 shows the mining plan for the site. No mining or other disturbance will <br />take place within 30 feet of any adjoining property <br />Prior to any mining operations, the sediment control system will be installed, which consists of a 1.0 <br />feet high berm made of topsoil on the south side of the property, which is meant to isolate runoff <br />water on the site until gravel excavation will make a depression which will contain all mnoff. Top- <br />soil will be removed from the Phase 1 area (3.2 acres) to a depth of 1.0 feet and will be stockpiled <br />on the southeast side of the permit area until reclamation. This volume is 3.2 acres x 1.0 feet = 5162 <br />cubic yards. The southeast stockpile area contains 5400 cy, therefore it is adequate to contain the <br />topsoil. Overburden will be stored on the northeast flat part of the permit area near the north access <br />road. These piles hold 3900 cy. Since overburden will be stripped to a thickness of 4.2 feet, the total <br />amount stripped from Phase 1 is 21680 cy. Since only 3900 cy can be stockpiled to the northeast, [he <br />difference must be stored temporarily on the Phase 2 area (17780 cy). All temporary stockpile <br />slopes will not exceed 2H:1V. Temporary sediment control will be provided for the stockpiles by <br />placing a perimeter ditch around the stockpile of 1.0 feet depth and 2H:1V sideslopes. <br />The plan will utilize two access roads to the pit bottom; each will have a gravel surface, 24 feet <br />width and slopes of approximately 6H:1V or milder. <br />The gravel will now be mined to a thickness of approximately 15-16 feet, until the Mancos Shale is <br />reached. Drilling of the site confirmed that the thicknesses given here are accurate. The total depth is <br />as follows: <br />19 Road Pit 10/02 <br />
