MINING PLAN AND TIMETABLE EXHIBIT D(CONT) area will include stripped, partially mined, partially reclaimed, the Plant Site area, materials stockpile area, settling pond fa- cility and the slurry wall around future reservoir areas . As mining progresses across the property some parts of the property will remain undisturbed while other areas will be either stripped, mined, partially reclaimed or totally reclaimed. The EXHIBIT C-1 -MINING PLAN MAP provides information of how the Phases will develop during mining. Initially the 205 acres would include having stripped and partially mined Phase 1, the 50 acre Plant Site and installed the slurry wall around Phase 1 . Much of the 205 acres would be within the highwater line of the reservoirs that would be covered with water and would need no soiling or revegetation. This amount of disturbance may change as the mine develops but prior to exceeding the initial 205 acres, a Techni- cal Revision will be filed to increase the bond and allow for more disturbance. This map shows the estimated location of the final slopes around the perimeter of the entire areas to be mined. The esti- mated reservoir highwater line, bank areas to be armored, the top of mining slope and slurry wall locations are shown. It also shows the maximum working face (highwall) for each Phase and the estimated cut/fill volume per foot to grade the working face highwall back to 3h to lv. No more than 1000 feet of total per- manent bank sloping will be needed (500 ' on each side of highwall) . The volume to complete the backfilling on the exte- rior slopes is shown. In Phase 2 this volume will be greater because any area mined within 300 feet of the river bank will be backfilled so a 300 foot setback can be maintained when the res- ervoirs are built . This river bank excavation area will be done in 500 feet or less section that will not be left open for more the 12 months before backfilling, sloping and armoring begins in any given section. Of the 472 . 40 acres ± in the permit area, approximately 388 . 12 acres ± will be disturbed by mining. Within the disturbed area 364 . 71 acres will be mined. The 23 . 41 acres of unmined area will be the setback margins between the slurry wall and the top of slope into the reservoirs . This area will contain roads for access to the reservoir areas during and after mining. EXHIBITF- RECLAMATION PLAN MAP shows how the reservoirs will be developed. As mining progresses a reservoir area will be sold and a condition of the sale may require LGE to permit the owner of the L.G. EVERIST, INC-WEST FARM RESERVOIRS May 2023 10
