Exhibit D <br />Reclamation Plan <br />JD -6 Mine Permit Amendment <br />M -1977 -310 <br />Cotter Corporation will restore the affected areas in accordance primarily with DOE's <br />lease requirements on the JD -6 lease and DRMS requirements. The land will he <br />reclaimed for range and wildlife habitat to meet DOE's directive to return the land as <br />closely as possible to the pre- mining land use. <br />This area of Montrose County is zoned agricultural -open. The current land use is <br />predominantly mining and grazing, as is the majority of the land in the near vicinity of <br />the mine site. The proposed post- mining land use for range and wildlife habitat should <br />improve forage and habitat for both wildlife and stock. <br />Mine Waste and Portal Area <br />The reclamation plan for the mine waste and portal area is to remove the dry building that <br />is located near the portal area, and re- contour the waste dump on the north end to a 3:1 <br />slope using a D -6 dozer or equivalent. The southeastern side of the waste dump will be <br />graded to a 2:1 slope by using a Cat 315 excavator or equivalent to move the material <br />near the crest back toward the center of the waste dump to achieve a 2:1 final slope, and <br />minimize the waste material moving into the drainage on the eastern side of the mine <br />waste dump. The remaining sides of this mine waste area will be re- contoured to a <br />211:1 V slope using a D -6 dozer or equivalent, which will allow it to more readily blend in <br />with the surrounding topography. <br />The mine portal will be backfilled with material immediately below the ore pad area and <br />other mine waste material to a depth where competent ground is encountered, and then <br />mine waste will be graded into the hillside around the portal area. Once re- contouring of <br />portions of the mine waste dump is complete,the previously stockpiled soil cover material <br />will be spread out to lightly cover the mine waste material prior to seeding. This <br />approach has been used at quite a few previously reclaimed DOE /Cotter reclamation <br />efforts, and has proven to be very effective with this type of mine waste material when <br />available soil is limited, as is the case here. <br />At this time it is anticipated that the south facing slope of this mine waste dump will be <br />pocked using a Cat 315 excavator, or equivalent, following placement of soil cover <br />material. The south facing slope will be pocked in an effort to enhance the moisture <br />retention potential, and hence the re- vegetation potential of this portion of the mine waste <br />dump. Experience in the immediate vicinity indicates that pocking the side of the waste <br />dump, or some equivalent roughening of the slope, will provide a more sustainable re- <br />vegetation effort. <br />Once the re- contouring is completed the stockpiled soil cover material from this area will <br />be spread over the recontoured waste material. The depth of this soil cover material is <br />anticipated to be 1 " -3 ", but will be dependant on the amount of silt material salvaged <br />from the catchment pond prior to reclamation. <br />D -1 <br />
