Exhibit C—Mining Plan <br /> (a) Mining Dates <br /> Mining will commence upon completion of the entire permitting process,which may be on or before <br /> September 15, 2007. Mining is anticipated to last of 20 years with an initial possible immediate production <br /> of 20,000 to 30,000 ton during the first year. Production at the site will be mainly for rip-rap and larger <br /> boulders for river stabilization projects.The site is remote with a limited commercial market and rock and <br /> boulder production for local projects may place as materials are needed and then selectively scaled from the <br /> outcrop. <br /> Mining will begin along the reclaimed margins of the previous DRM&S Permit#M-1994-022.The flatter <br /> elevation area at the top of the access ramp will be used as before for an operations/temporary stockpiling <br /> area. Mining will start and follow the limits of the previously disturbed areas and will move along the <br /> general existing slope and (rock) high-wall (very slowly) extending the disturbed area to the west and north. <br /> The fractured and weathered rock(possible upper 2 to 4 feet to solid un-weathered bedrock)will be <br /> removed off the slopes or scaled off eh more sheer faces as/when necessary. Due to the nature of the <br /> outcrop,the sheer faces and limited annual production from the site the total disturbed area at the end of <br /> 20 years would be less than 6 acres. (Note: the 20 yr. limit line on Exhibit E Map) <br /> Process equipment operation at the site would be temporary.The operations area is restricted so <br /> equipment may be mobilized as contracted material or stockpiles are needed. Estimated mining activities at <br /> the site would average less than 180 days per year.The number of days the mine operates depends on <br /> demand for the material that are sold. As demands increase the days of operation increase,as the demand <br /> decreases the days of operations will also decrease.Weather such as cold, rain, snow, and heat will affect <br /> days of operation.These materials are used mainly for river stabilization projects. We have another gravel <br /> pit that also requires our time. <br /> (b) Topsoil—soil suitable as a plant growth medium <br /> All of the soil within the 8.14 proposed permit area, as mapped and described by the U.S.D.A.Soil <br /> Conservation Service in this area of Moffat County consists of soils belonging to the Ustorthents,Fridgid— <br /> Borolls Complex,25—75%slopes.These soils at the site are very well drained and have very little water <br /> holding capacity. Soil depth is shallow and thin and grades to un-weathered bedrock. Permeability is slow <br /> and runoff is high. Due to the steep slopes and limited soils and vegetation the area is unsuitable for <br /> livestock grazing although wildlife and livestock do occasionally use some of the side and upper slopes. <br /> There is very little topsoil/surface soil at the site.The proposed mine area is predominately weathered <br /> basalt outcrop and bedrock and has been assigned a "none" rating as an ecological site by the NRCS.Any <br /> and all topsoil and/or suitable surface material including some possible crusher fines will be reserved for site <br /> reclamation.The folded bedded basalt outcrop material at the site forms very high angle slopes and cliffs of <br /> bare rock with no topsoil. (see photos) <br /> All of the soil within the .62 proposed permit storage area the Evabot Yamo Complex of soil is a loam soil <br /> that has H1—H3 as a loam soil that is 60" deep. With the depth of topsoil being that deep and being a <br /> storage area not a mining area the plan is to clean up all the storage from the surface with very little topsoil <br /> removal. Loosen the compacted soil then seed the disturb area. <br /> (c) Thickness of overburden or quantity of waste rock <br /> Overburden within the 8.14 proposed permit area is minimal and is sufficient quality(fractured and <br /> weathered basalt mixed rock)to be used in base course and fill material. Material below the salvageable <br /> surface/topsoil horizon will be mined and hauled unless used onsite for access ramps or storm-water berms. <br /> There will be no stockpiles of waste rock or overburden. Boulders and large rip-rap may be mined and/or <br /> scaled from steeper areas as needed. Some scaling and rock fall mitigation will be done as necessary on the <br /> higher angle slopes and cliffs above the county road. Rock fall and slide rock will be collected from the slope <br /> toe and roadside to assist in county maintenance. <br />
