Exhibit D <br /> Page 15 <br /> The Year 3 mining activity will continue the westerly advance across Section 3, and is anticipated to <br /> encompass approximately 93.0 acres,with an anticipated ROM production of approximately 5.1 million <br /> tons.Approximately 888,000 cubic yards of process discard are anticipated to be produced and placed <br /> within the PDS during Year 3. <br /> • Year 4 Mining Activity(Central Portion of Section 3) <br /> Year 4 pre-strip(of growth medium)is anticipated to generate an estimated 122,000 cubic yards of <br /> material,of which an estimated 88,000 cubic yards is anticipated to be dedicated to ongoing concurrent <br /> reclamation,with an estimated 34,000 cubic yards slated to go to the long-term storage stockpile(TS-1). <br /> This would result in approximately 54 acres of incremental reclamation(largely within the Year 3 mining <br /> block),while bringing the total reclaimed acreage to approximately 96 acres and the cumulative stored <br /> volume within TS-1 to approximately 396,000 cubic yards. <br /> The Year 4 mining activity will continue the westerly advance across the center of Section 3,and is <br /> anticipated to encompass approximately 76.1 acres,with an anticipated ROM production of approximately <br /> 5.1 million tons.Approximately 888,000 cubic yards of process discard are anticipated to be produced and <br /> placed within the PDS during Year 4. <br /> • Year 5 Mining Activity(West-Central Portion of Section 3) <br /> Year 5 pre-strip(of growth medium)is anticipated to generate an estimated 114,000 cubic yards of <br /> material, of which an estimated 71,000 cubic yards is anticipated to be dedicated to ongoing concurrent <br /> reclamation,with an estimated 43,000 cubic yards slated to go to the long-term storage stockpile(TS-1). <br /> This would result in approximately 44 acres of incremental reclamation(largely within the Year 4 mining <br /> block),while bringing the total reclaimed acreage to approximately 140 acres and the cumulative stored <br /> volume within TS-1 to approximately 439,000 cubic yards. <br /> The Year 5 mining activity will continue the westerly advance from the center of Section 3, and is <br /> anticipated to encompass approximately 71.0 acres,with an anticipated ROM production of approximately <br /> 5.1 million tons.Approximately 881,000 cubic yards of process discard are anticipated to be produced and <br /> placed within the PDS during Year 5. <br /> Limited-scale"advance"reclamation will be carried out on a portion of the PDS,which, at the end of Year <br /> 5 is estimated to contain a total volume of approximately 4.4 million cubic yards,encompassing an <br /> approximately 50-acre area at an estimated height of approximately sixty-three(63)ft Thus,as measured <br /> from its pit floor foundation,the waste stockpile feature should rise approximately 30 to 33-ft above the <br /> surrounding natural topography. Successive lifts will be established such that a 3H: 1V or 5H:l V side- <br /> slope(on active areas),consistent with the material's natural angle of repose,is maintained. <br /> Note: At the end of Year 5,CSC has estimated total disturbance to be on the order of 557 acres, of <br /> which 182 acres will have been subject to concurrent reclamation (and as such, in the post-reclamation <br /> monitoring and maintenance phase),thus leaving approximately 375 acres that would be classified as yet- <br /> to-be reclaimed. <br /> Colorado Sand Company II, LLC <br /> Kersey Mine Construction Material Regular(112)Operation Reclamation Permit Application <br /> June 7,2024 <br />
