MINING PLAN EXHIBIT D(CONT) <br /> The site is currently used as rangeland and consists of a <br /> gravel terrace paralleling the southern side of the Huerfano <br /> River valley. The usable materials on this site ranges from 5 to <br /> 50+ feet deep. The soil covering the gravel averages 0 to 5 <br /> inches deep with a layer of overburden ranging from 0 inches to 9 <br /> feet deep . <br /> The permit boundary starts in the southwest corner at a <br /> point east of the north/south fence north of the gate . The fence <br /> lines on the west, south and east sides do not lie on the <br /> ownership lines so they will be located and then a shallow ditch <br /> will be placed on the inside edge of the lines to delineate the <br /> permit boundary to the top of the bluff on the north. The north <br /> line will be the center of the Huerfano River. <br /> The existing on site road is gravel with graded runoff <br /> ditches on each side . It is 20 feet wide with a slight crown to <br /> allow for drainage . This road will be maintained for use as a <br /> haul route and access for the property owners . Any runoff from <br /> the road will be retained on site and allowed to soak into the <br /> ground or evaporate . The road will be maintained for the life of <br /> the mine and a scale and scale house will be placed on the road <br /> near the access point . <br /> SOILSAND OVERBURDEN <br /> The SOILS MAP in EXHIBIT I shows the soil types as delineated by <br /> the National Resource Conservation Service (NRCS) obtained from <br /> the internet WSS web site . The information contained in EXHIBIT I/J <br /> will provide background levels for the site as reclamation begins <br /> on the entire area. <br /> There are 5 types of soils found on the site . These soils <br /> are typical throughout the Huerfano River valley. They have no <br /> unusual qualities and three of the soils will not be disturbed by <br /> mining. <br /> The three undisturbed soils are designated as map units : 22- <br /> Glenberg sandy loam, 0 to 20 slopes, 24-Haverson clay loam, 0 to <br /> 30 slopes, and EL-Ellicott-Las Animas complex, 0 to 20 slopes. <br /> The other two, 77-Schamber-Midway complex, 3 to 250 slope and 92- <br /> Willowman, Complex 0 to 20 slopes cover the area to be mined. <br /> See the soils map in the NRCS report for how the soils are <br /> distributed on the permit area. More detail information <br /> including, the soils description and engineering qualities, can <br /> be found starting on page 25 in this application. <br /> 7 <br />
