depending on the condition of the Creek at closure. GIR will photograph the Creek and banks during the <br /> summer of 2021 to document original conditions. Creek banks will be regraded as necessary and <br /> revegetated. Photographs will inform creek bank revegetation. GIR may use species listed in Table 2 <br /> initially to prevent erosion of the bank but will include willows and alders, sedges, and shrubs during <br /> creek bank revegetation. <br /> 1 .6 Wetlands <br /> The wetlands (0.224-acres(9,748 sq.ft.)) around Coon Track Creek will be reclaimed by replanting with <br /> native wetland species (See Exhibit D, Section 1.9). Species may include those listed in Table 3. Willows <br /> and shrubs will be hand planted. <br /> 1 .7 Roads <br /> The new road between Cross and Caribou mines will be reclaimed. The new road between the Cross <br /> and Caribou mines will be approximately 885 feet in length by 30 feet in width,with an additional 5 feet <br /> of disturbance on both sides of the road.The total area of the road and disturbance area equals 0.609 <br /> acres.The Coon Track Creek culvert along with all other road structures (anchors, riprap,foundations) <br /> will be removed along with road base and materials. These materials will be disposed of in an approved <br /> facility such as the Republic Services Foothills Landfill (approximately 29.5 miles to the east). Road <br /> materials along the portion of the road traversing the wetland will be removed and disposed of in an <br /> approved facility such as the Front Range Landfill in Erie, Colorado (approximately 40 miles east). The <br /> remainder of the road will be re-graded to approximate the original topography. Berms will be knocked <br /> down and regraded with the surrounding area. Additional fill material will be used as necessary to fill <br /> the road cuts and restore the slopes to natural contours. Roads will be revegetated in accordance with <br /> Exhibit D,Sections 1.8 and 1.9. <br /> The Caribou Level 300 road (approximately 0.0006 acres) will be regraded and tilled prior to <br /> revegetation in accordance with Exhibit D, Section 1.9. <br /> 1 .8 Soil Preparation and Revegetation <br /> Surfaces for revegetation will be roughed to gain a mechanical bond between the subgrade and the <br /> replaced topsoil. Where the subgrade is of acceptable quality, it may include disc plowing the topsoil <br /> and subgrade together where there is access and safety is not compromised. Where equipment can <br /> operate without compromising safety,the seedbed will be loosened (four to six inches (4" to 6") deep) <br /> and smoothed. At locations where equipment cannot operate, the seedbed will be prepared by hand, <br /> scarifying to a minimum depth of one inch (1") (DRMS 2009). <br /> GIR will replace topsoil in as even a manner as equipment allows.Topsoil will be sourced locally in <br /> Nederland, CO. Because of the thin soil types at this site, there is no available site soil for reclamation. <br /> Soil amendments will be as recommended by the local NRCS. Currently, they recommend that if soil <br /> tests are not performed,forty(40) pounds per acre of each of the major nutrients(nitrogen and <br /> phosphoric acid [H3PO41) be applied. They also recommend a combination of mulch or other organic <br /> matter and a nutrient source such as well-cured feedlot or barnyard manure be applied.The <br /> recommended application rate should be at least twenty (20) tons per acre,evenly spread.The manure <br /> 7 <br />
