MINING PLAN AND TIMETABLE EXHIBIT D(CONT) reservoir to start construction of facilities related to the res- ervoirs) - such as installation of pump houses, inlet/outlet structures, rip-rap, etc. This would only happen if the reservoir owner does not want to wait for DRMS permit acreage release of that Phase. In this case, L.G. Everist would have already re- claimed the reservoir phase (including liner certification, final grading of the reservoir slopes, armoring and initial seeding) , but the phase acreage is not yet released from the DRMS permit (due only to vegetation growth) . L.G. Everist would file Techni- cal Revisions as needed to incorporate the changes . At any given time, mining and "concurrent reclamation" may be occurring in one or more phases to accommodate the blending of materials, the natural progression of mining from one Phase to the next . This concurrent reclamation allows for reclamation work being completed in one phase while mining begins in another phase. The "direction of mining" arrows on EXHIBITC-1 -MINING PLAN MAP show the applicant ' s best guess on how mining will progress through the mine areas at this time. Natural ground conditions and un- foreseen circumstances may necessitate changes to the mining di- rection throughout the life of the mine. The RECLAMATIONCOSTESTIMATE-EXHIBITLis based on the Operations Stage A plan to bond for initial setup of the Plants Site and support facilities . Included is an estimate for the Operations Stage B where it is based on an estimated disturbance area when the Phase 1 has been open for a few years . The acreage disturbed may increase or decrease as mining progresses . If it increases, a Technical Revision will be filed to adjust the bond amount to cover the changed cost estimate. Mining will start on the southwest of Phase 1 and progress to the east and south until the mining limits are reached. This will leave an open working face across the Phase as shown on the MINING PLAN MAP. This face will have a 14: 1 slope and will be worked to the north, the exterior final slopes will be constructed us- ing the overburden or shale from the excavated floor material. If mining ends prematurely, the east/west working face will be re- claimed using a cut/fill sloping method instead of backfilling. The setbacks to be used in each Phase are shown in the table on the EXHIBIT C-2-STRUCTURES MAP. The aggregates will be removed and stored on the Plant Site area in Phase 4 for processing. The plan is to use conveyors or off-road haul trucks to move the ma- L.G. EVERIST, INC-WEST FARM RESERVOIRS May 2023 11
