EXHIBIT D MINING PLAN(CONT) MINING PLAN MAP EXHIBIT C-1 - MINING PLAN MAP shows the approximate direction of mining as it progresses across the site. Initially the plan is for having 180 acres ± of disturbance bonded in Phases 1, lA and 3 to allow for flexibility during mining. This 180 acre area will include stripped, partially mined, partially reclaimed areas . The Plant Site, materials stockpile areas, armored banks where needed and future reservoir areas . As mining progresses across these Phases some parts of the areas will remain undisturbed while other areas will be either, stripped, mined, partially reclaimed or totally reclaimed Under this initial plan Phase lA will be mined and used as settling pond area. The interior slopes will be mined 3h to lv so only backfilling, resoiling and seeding would be needed. Phase 1 would have the slurry wall installed but not certified; all exterior slopes will be graded except where next to the working face . The in-progress items like working face and adjoining slope areas, the bank armoring and reclaiming stripped area will be limited but move from Phase to Phase as Mining progresses . Bank Sloping will not exceed 2600 feet, leaving final grading from %: 1 to 3 : 1 . Bank armoring material will be recycled concrete with all surface exposed rebar removed. LGE will commit to having enough material to armor a minimum of 1000 feet reservoir bank on the mine at one time . The 2350 cubic yards needed for a 1, 000 foot long section will be stored adjacent to the armoring area and parallel to the rivers flow. The armoring will be installed as the final slopes are constructed using the method and volumes shown in the Bank Armoring Plan presented in the APPENDIX. The area needing resoiling would be a maximum of 30 . 0 acres, this includes the pre-mining stripped area and the area above-water around the reservoir that need to be resoiled, graded and seeded. EXHIBIT L- RECLAMATION COSTS contains the acreages, volumes and estimated unit costs that explain the work needed to reclaim the disturbance when this is taking place. Of the 643 . 30 acres ± in the permit area, approximately 508 acres ± will be disturbed by mining. This mining plan details the development of the mine site with 2 options . Option A will has a series of eight (8) developed water storage reservoirs using slurry walls around each reservoir. Option B has six (6) lined water storage reservoirs, due to some of the reservoirs being combined if some existing oil and gas wells and pipelines can be relocated or are abandoned and removed. MAP EXHIBIT F - RECLAMATION PLAN MAP -OPTION A and MAP EXHIBIT F - RECLAMATION PLAN MAP - OPTION B show how these options will be developed. More detail is discussed in the following text . The methods discussed below will fit each option unless otherwise stated. Technical Revisions will be filed when needed to incorporate various items from Option B. As stated above, most of the Option B changes are related to oil and gas facility relocations and removals . Other possible Option B changes could occur if the landowners want to start development of facilities related to their developed water storage in a reservoir phase - such as pump houses, inlet/outlet structures, rip-rap - and don' t want to wait for DRMS permit acreage release .
