Exhibit D <br /> Page 16 <br /> • Years 6- 10 Mining Activity(West Portion Section 3 and Shift Over to Section 11) <br /> Year 6 and early Year 7 will complete mining within the north pit,with pit advance to the west being <br /> limited by the presence of oil and gas infrastructure. Mining will then shift to the southeast pit, starting in <br /> the southern portion of Section 2 in the latter portion of Year 7,advancing in a southerly direction toward <br /> TMDZ-1, at which time mining shifts over to the southwest pit,opening that area during the latter portion <br /> of Year 10. <br /> Year 6: The Year 6 mining activity is anticipated to be carried out along the western extent of Section 3, <br /> followed by the start of Year 7,which effectively completes active mining within Section 3,as pit advance <br /> approaches(and terminates at)the fenced boundary line delineating the presence of the major oil and gas <br /> infrastructure along the western edge of Section 3. Planned production over the projected 79.5-acre mine <br /> block is set at approximately 5.1 million tons for the year.Approximately 67,000 cubic yards of growth <br /> medium are slated for use in concurrent reclamation,while approximately 61,000 cubic yards are <br /> anticipated to be added to TS-1,bringing the cumulative total of TS-1 stored material to approximately <br /> 500,000 cubic yards. Some 886,000 cubic yards of process discard are projected to be placed in the PDS, <br /> bringing the total volume in the PDS to approximately 5.3 million cubic yards. <br /> Year 7: Only a minor portion of the Year 7 mining activity is anticipated along the extreme western edge <br /> of Section 3,and during Year 7 mining activity shifts over to the eastern/southeastern mining area,with a <br /> new box cut in the southern quarter of Section 2(south of the processing plant area). Mining advance <br /> continues in a southerly direction toward the Section 2/Section 12 common line. Planned production over <br /> the projected 136-acre is set at approximately 5.1 million tons for the year. Approximately 171,000 cubic <br /> yards of growth medium are slated for use in concurrent reclamation,while approximately 46,000 cubic <br /> yards are anticipated to be added to TS-1,bringing the cumulative total of TS-1 stored material to <br /> approximately 546,000 cubic yards. Some 880,000 cubic yards of process discard are projected to be <br /> placed in the PDS,bringing the total volume in the PDS to approximately 6.2 million cubic yards. <br /> Year 8: The Year 8 mining activity,carried out in the northern portion of Section 12,encompasses further <br /> advance to the south,with a gradual narrowing of the pit due to the presence of major oil and gas <br /> infrastructure features located to the west of the pit area. Planned production over the projected 135.1-acre <br /> mine block is set at approximately 5.1 million tons for the year. Approximately 171,000 cubic yards of <br /> growth medium are slated for use in concurrent reclamation,while approximately 46,000 cubic yards are <br /> anticipated to be added to TS-1,bringing the cumulative total of TS-1 stored material to approximately to <br /> its anticipated peak volume of approximately 592,000 cubic yards. Some 884,000 cubic yards of process <br /> discard are projected to be placed in the PDS,bringing the total volume in the PDS to approximately 7 <br /> million cubic yards. <br /> Year 9: The Year 9 mining activity similarly continues the southerly advance through the east-central <br /> portion of Section 12,with a continued narrowing(west to east)of the pit. Planned production over the <br /> projected 129.2-acre mine block is set at approximately 5.1 million tons for the year. The full extent <br /> (approximately 211,000 cubic yards)of pre-strip growth medium is slated for use in concurrent <br /> reclamation,in addition to approximately 4,000 cubic yards to be taken from TS-1,bringing the <br /> cumulative total of TS-1 stored material to approximately 588,000 cubic yards. Some 882,000 cubic yards <br /> of process discard are projected to be placed in the PDS,bringing the total volume in the PDS to <br /> approximately 7.9 million cubic yards. <br /> Colorado Sand Company II, LLC <br /> Kersey Mine Construction Material Regular(112)Operation Reclamation Permit Application <br /> June 7,2024 <br />
