Exhibit D (Cont) <br /> Mining Plan <br /> 1976 there is little or no topsoil on the site for this area . <br /> This pre-law area is outlined on Map Exhibit C. <br /> The soils are designated as map units : CaE-Cascajo gravely <br /> sandy loam, 5 to 25% slopes, OdA-Oterodry sandy loam, dry, 1 to <br /> 4% slopes, OrD-Otero Gravely sandy loam, 3 to 90 slope and RfB- <br /> Rocky Ford silty clay loam, 1 to 3a slopes. See the soils map in <br /> the NRCS report for how the soils are distributed on the permit <br /> area. More detail information including, the soils description <br /> and engineering qualities, can be found starting on page 24 in <br /> this application. <br /> Based on the soils report and on site observations there are <br /> sufficient quantities of soil available to reclaim the slope from <br /> the original surface to the mine floor or on areas where the <br /> growth medium was present when mining started. On the pre-law <br /> disturbed lands the area will be graded and graveled so the <br /> landowner can use it as they wish. <br /> The soils in this area when salvaged and replaced should be <br /> capable of growing vegetation consistent with what is there now. <br /> The average depth of topsoil on the site according to the NRCS <br /> report is 10 to 12 inches deep . Using 10 . 0 inches as the average <br /> we calculate there should be a minimum of 11, 300 YD3 of growth <br /> medium available for resoiling the slopes around the mine floor . <br /> Be assured that enough growth medium will be retained on the site <br /> to assure reclamation and revegetation is successful on those <br /> areas that have soil on them now. On the old mine area no soil <br /> will be replaced since none exists now, rather the area will be <br /> graveled to stabilize it . The growth medium stockpiles will be <br /> located around the excavation (their approximate locations are <br /> shown on the MINING PLAN MAP to reduce the haul distances when <br /> reclamation starts . If the soil and overburden stockpiles remain <br /> undisturbed for more than one year a cover crop of Western <br /> Wheatgrass at a rate of 2 pounds-pls/100 sq-ft will be planted on <br /> them. <br /> MINING PLAN <br /> We anticipate the life of this mine to be between 10 <br /> and 15 years depending on the amount of material in the mine and <br /> the market demand. The site is currently used as an existing <br /> gravel mire and material storage yard for construction material <br /> obtained from other sources besides the mine . The storage area <br /> on the old mine floor is used to clean and process the material <br /> 8 <br />
