EXHIBIT D MINING PLAN (coNT) <br /> development of the mine site with 2 options . Option A will has a <br /> series of eight (8) developed water storage reservoirs using slurry <br /> walls around each reservoir. Option B has six (6) lined water <br /> storage reservoirs, due to some of the reservoirs being combined if <br /> some existing oil and gas wells and pipelines can be relocated or <br /> are abandoned and removed. <br /> MAP EXHIBIT F - RECLAMATION PLAN MAP -OPTION A and MAP EXHIBIT F - <br /> RECLAMATION PLAN MAP -OPTION B show how these options will be <br /> developed. More detail is discussed in the following text . The <br /> methods discussed below will fit each option unless otherwise <br /> stated. Technical Revisions will be filed when needed to <br /> incorporate various items from Option B. As stated above, most of <br /> the Option B changes are related to oil and gas facility <br /> relocations and removals . <br /> Other possible Option B changes could occur if the landowners <br /> want to start development of facilities related to their developed <br /> water storage in a reservoir phase - such as pump houses, <br /> inlet/outlet structures, rip-rap - and don' t want to wait for DRMS <br /> permit acreage release. In this optional case, L.G. Everist would <br /> have already reclaimed the reservoir phase (including liner <br /> certification, final grading of the reservoir slopes, and initial <br /> seeding) , but the phase acreage is not yet released from the DRMS <br /> permit (due only to vegetation growth) . L.G. Everist would file <br /> Technical Revisions as needed to incorporate the changes . <br /> Please refer to MAP EXHIBIT C-1 - MINING PLAN MAP during review of <br /> the following text for the location of the areas discussed. <br /> At any given time, mining and reclamation may be occurring in <br /> one or more phases to accommodate the blending of materials, the <br /> natural progression of mining from one Phase to the next, and the <br /> relocation of the processing plant and settling ponds . This <br /> "concurrent reclamation" allows for reclamation work being <br /> completed in one phase while mining begins in another phase . <br /> The "direction of mining" arrows on MAP EXHIBIT C-1 -MINING PLAN MAP <br /> show the applicant ' s best guess on how mining will progress through <br /> the mine areas at this time. Natural ground conditions and <br /> unforeseen circumstances may necessitate changes to the mining <br /> direction throughout the life of the mine. <br /> The RECLAMATION COST ESTIMATE- EXHIBIT L is based on an estimated <br /> disturbance area when the mine has been open for a few years . The <br /> acreage disturbed may increase or decrease as mining progresses . <br /> If it increases, a Technical Revision will be filed to adjust the <br /> bond amount to cover the changed cost estimate . <br /> Initial mine development will begin on the south end of Phase <br /> 3 and in Phase 1A where the topsoil and overburden will be stripped <br /> L.G Evenst,Inc Ragsdale Reservoirs May 5,2020 <br /> 9 <br />
