Exhibit E <br /> Page 5 <br /> Topsoil Segregation,Preservation,and Replacement <br /> The initial eight(8)years of mining operations(i.e.,as associated with growth medium pre-strip)will contribute(in <br /> large part)to a build-up in the total volume of the TS-I stockpile sufficient to accommodate fmal site closure <br /> requirements;however, limited volumes(i.e., the remainder)will be dedicated to initial(concurrent)reclamation <br /> efforts. The TS-1 peak volume of approximately 592,000 cubic yards of material is anticipated to be reached in Year <br /> 8,with a minor decline(in total volume)occurring thereafter,while maintaining sufficient volume to address fmal <br /> site reclamation obligations. <br /> Under steady-state conditions(and once sufficient pit void has been developed to accommodate early-stage <br /> placement of material in TS-1 and the PDS,respectively), it is anticipated that the material balance will approximate <br /> that depicted in Table E-1: Reclamation Sequence and Projected Material Balance.Concurrent reclamation will <br /> be carried out in a manner that allows pre-stripping of growth medium in advance of the pit progression with that <br /> same material being back-hauled to previously mined out areas and/or TS-1,as per requirements. In general,pre- <br /> stripping will be limited in areal extent in order to minimize the potential for wind-borne dust generation and erosion <br /> concerns; a typical pre-strip area will generally comprise approximately 15-to 20 acres,typically immediately in <br /> front of the advancing active mine face. <br /> The TS-1 stockpile will be established with 5H: 1 V(nominal)side slopes to ensure long-term stability while <br /> facilitating(interim)revegetation efforts. Temporary seeding(and reseeding,as may be required)will be utilized to <br /> establish and sustain an interim vegetative cover,which in turn will enhance the feature's resistance to wind-borne <br /> and/or precipitation induced erosional effects.At its full build-out capacity of approximately 592,000 cubic yards, it <br /> is estimated that the TS-1 stockpile will occupy an approximately 21-acre footprint area(refer to Exhibit D-2: Mine <br /> Plan). <br /> It is anticipated that concurrent reclamation will commence in Year 3 and continue through to the end of LOM(i.e., <br /> Year 20)on an annual basis. Accordingly,growth media will be removed in advance of mining and subsequently <br /> directly placed behind mining activities in a nominally equivalent thickness of 8 to 12-inch depth. Seeding of this re- <br /> established growth medium will occur,typically each fall. <br /> Stabilization,Grading,and Compaction of Spoil <br /> There will be no "spoil"generated during the mining activities conducted at the Kersey Mine, as there is no <br /> "overburden",per se. Only the aforementioned"growth medium" overlies the target sand resource that is to be <br /> mined. Aspects pertaining to pre-stripping(salvage), stockpiling,and stabilization are addressed above. <br /> With concurrent reclamation(under steady-state conditions), virtually all growth medium generated by pre- <br /> stripping(in advance of mining)will be placed atop a prior year's(mined out)pit floor,except as may be otherwise <br /> noted in Table E-1: Reclamation Sequence and Projected Material Balance. In areas where the sand resource <br /> base is less than the nominal 30-ft thickness(resulting in the mining of an incrementally larger surface area to <br /> accommodate annual ROM requirements), surplus growth medium will generally be transported to the TS-1 long- <br /> term stockpile. <br /> In the pre-strip operation,the material will be excavated utilizing front-end loaders and/or hydraulic excavators.Due <br /> to the nature of the material(and the method of excavation),the material will remain in a loose, unconsolidated <br /> Colorado Sand Company II, LLC <br /> Kersey Mine Construction Material Regular(112)Operation Reclamation Permit Application <br /> June 7,2024 <br />
