MINING PLAN EXHIBIT D(CONT) <br /> south side is used by the property owners as undeveloped open <br /> lands and to the north across the Huerfano River the property <br /> owners have irrigated grasslands . The Perrino' s have a ranch <br /> yard and house on the northwest side of the permit area and own a <br /> school house on the access road east of the house area. At this <br /> time both structures will remain so we plan to establish a mining <br /> setback of 200 feet from the main structures in those areas . <br /> Along the north side of the terrace is a near vertical face <br /> that exists along the transition area from the rangeland down to <br /> the river bottom. The area north of that is river bottom land. <br /> This face appears to have been created by past flood events on <br /> the Huerfano River. It is marked by erosion channels where <br /> water has run off the rangeland into the river bottom. No <br /> disturbance will take place north of the permit line in the river <br /> bottom or on the existing slope into the river. <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 around the mine area to delineate the permit <br /> boundary. The north line for the Affected Lands/Permit Line is <br /> the southern R.O.W. line for the San Isabel Electric Association <br /> powerline . The powerline ROW is 25 feet each side of the power <br /> poles . <br /> The existing, on site road is gravel with graded runoff <br /> ditches on each side . <br /> It is 20 feet wide <br /> with a slight crown to allow for drainage. This road will be <br /> maintained for use as a haul route and access for the property <br /> owners . Any runoff from the road will be retained on site and <br /> allowed to soak into the ground or evaporate. The road will be <br /> maintained for the life of the mine and a scale and scale house <br /> will be placed on the road near the access point . <br /> ends . , <br /> 7 (Revised 6/1/17) <br />
