1 .3 Waste Rock Piles <br /> There are three existing waste rock piles(Exhibit E, Map 7).The majority of the waste rock will be <br /> eliminated prior to reclamation. GIR has entered into an agreement to deliver waste rock to Colorado <br /> Aggregate Recyclers in Golden CO (approximately 22 miles to the south east). GIR will retain <br /> approximately 20,000 yards of waste rock on site for site needs. <br /> The waste rock pile foot prints will require reclamation if the waste rock has been repurposed,once <br /> mining ceases.The waste rock pile foot prints are estimated not to exceed 0.99 acres.Their locations <br /> are shown on Exhibit E—Maps 6 and 7. Waste rock pile footprints will be reclaimed in accordance with <br /> the procedures in Exhibit D, Section 1.8. <br /> If at closure not all waste rock has been repurposed,the remaining waste rock piles will be contoured to <br /> provide mechanically stable piles that are visually compatible with the landscape and support <br /> revegetation. Slopes of the waste rock piles will be 3H:1V to prevent wind and water erosion.Void <br /> spaces within the top layer of the waste rock will be filled with suitable subsoil that will facilitate <br /> revegetation.The waste rock pile will be covered with a 2-ft thick topsoil mixture to support <br /> revegetation with native grasses. Runoff along the slope will be controlled with erosion and sediment <br /> control structures to minimize rill and gully formation, especially prior to establishment of vegetation. <br /> 1 .4 Ponds <br /> All five ponds (1, 2, 3A, 36, and 3C) will be reclaimed. After mining ends, water in the ponds will be <br /> allowed to evaporate. Any remaining water will be removed,tested and disposed off-site at Publicly- <br /> Owned Treatment Works such as the Nederland Sewage Treatment plant(approximately 5.8 miles <br /> south). Any sediment on the liners will be sampled and removed if required by regulatory requirements <br /> and disposed of in an approved facility.The pond liner will be removed and disposed off-site at an <br /> approved facility such as Republic Services Foothills Landfill (approximately 29.5 miles to the east).The <br /> pond areas will be filled in as necessary with waste rock to 2 feet below the surface, covered with <br /> topsoil, regraded to provide positive drainage to prevent ponding, and revegetated in accordance with <br /> Exhibit D, Sections 1.8 and 1.9. Pond slopes will be less than 2:1.The area of the ponds is approximately <br /> 0. 245 acres. <br /> Liners were removed from Ponds 3 A and B in 2019. Approximately 8 cubic yards of sediment was <br /> removed. GIR anticipates similar amounts will be removed from the other three ponds (4 cy per pond) <br /> and approximately 2 cy from Ponds 3A and 3B on closure. <br /> 1 .5 Coon Track Creek <br /> The road over and culverts in Coon Track Creek will be removed. Concrete and rock used in the <br /> construction of the road will be removed. Concrete will be disposed of at an approved facility such as <br /> the Republic Services Foothills Landfill (approximately 29.5 miles to the east).The Creek and Creek <br /> banks will be restored to as near to original conditions as possible (See Exhibit D,Sections 1.8 and 1.9). <br /> To restore flow conditions, natural rock and boulders, steps, or other techniques, may be used <br /> 6 <br />
