MINING PLAN EXHIBIT C (cont) <br /> the mine floor for use in reclamation. The operator will replace <br /> as much topsoil as salvaged, but this may be only enough to <br /> replace an average of 4 to 6 inches on the disturbed area. If <br /> the soil stockpiles remain undisturbed for more than one growing <br /> season a cover crop of Western Wheatgrass will be planted at a <br /> rate of 3 . 0 lbs pls/200 Ft2. <br /> As mining progresses into the deposit, the working face will <br /> be mined near vertical and will not exceed 550 feet long nor 40 <br /> feet high. The exterior slopes will be mined 3h to lv as mining <br /> reaches the mining limits . Resoiling and shaping will run <br /> concurrent with mining so that if mining ended prematurely only <br /> the working face and floor would need grading and resoiling. <br /> Of the 9. 90 acres ± in the permit area, approximately 8 . 67 <br /> acres ± will be mined, 1 .23 acres ± will be setbacks around the <br /> mined area or access road. These setbacks are shown on the Map <br /> Exhibits and are 15 feet wide where the mine abuts the Zuege' s <br /> land and 25 feet adjacent to adjoining owner property. They will <br /> be used as growth medium storage areas . This will leave a 25+ <br /> foot deep hole in the surrounding land with a gently sloping <br /> floor as shown on the Reclamation Plan Map-Exhibit E-3. <br /> Gravel processing may take place on the mine but in most <br /> cases the material will be hauled offsite as pit run material for <br /> use on projects in the vicinity. <br /> This mine will operate intermittently so when mining ends <br /> the working face will be temporarily graded 2 : 1 so it is stable <br /> during the inactive time period. The Reclamation Map shows the depth <br /> as 25 feet but it is believed the deposit may be deeper so the <br /> final floor may be deeper than shown. If this happens, a Techni- <br /> cal Revision will be filed to change the final depth. <br /> The material will be used to supply construction aggregates <br /> including road base and pit-run material for use on the land and <br /> for sale to other parties . The land will remain rangeland as <br /> mining progresses and once reclamation is complete the area will <br /> be reseeded so it will have the same use as now exists . <br /> The mine will be sloped so all surface water runoff can be <br /> contained on the site until reclamation is complete. The nature <br /> of the material will allow any surface accumulations of water to <br /> soak into the ground. All stormwater on the site will be di- <br /> rected into the active mine area and there will be no discharge <br /> or impounding of water for more then 72 hours . <br /> Zuege Mine, LLC Zuege Pit <br /> June 11, 2024 17 <br />
