EXHIBIT D MINING PLAN (CONT) Of the 667 . 97 acres in the permit area, approximately 510 acres will be disturbed by mining. This mining plan details the development of the mine site with 2 options . Option A has a series of eight (8) lined water storage reservoirs using slurry walls around each reservoir. OPTIONBhas 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 releases . In this optional case, L.G. Everist would have already reclaimed the reservoir phase (including liner certification, final grading of the reservoir slopes, and initial seeding areas outside the slurry walls) , but the phase acreage is not yet released from the DRMS permit (due only to vegetation growth) . Please refer to MAP EXHIBIT C 1 - MINING PLAN MAP during review of the following text for the location of the areas discussed. At any given time, mining and 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, and the relocation of the processing plant and settling ponds . This "concurrent reclamation" allows for reclamation work being completed in one phase while mining begins in another phase . The "direction of mining" arrows on MAP EXHIBIT C 1 - MINING PLAN MAPshow the applicant ' s best guess on how mining will progress through the Phases at this time. Natural ground conditions and unforeseen circumstances may necessitate changes to the mining direction throughout the life of the mine. Any structures owned by the Cannon Land Company that will not remain after reclamation is complete will be removed and disposed of properly, this applies to all Phases . Mining started on the south end of Phase lA and progressed to the north. The setbacks to be used are shown in the table on the MAP L.G. Everist, Inc. Ragsdale Reservoirs Revised February 11, 2025 15
