MINING PLAN EXHIBIT D(CONT) <br /> engineering qualities, can be found starting on page 25 in this <br /> application. <br /> Based on the soils report and on site observations there are <br /> sufficient quantities of soil available to reclaim the disturbed <br /> lands to their present condition. The soils in this area when <br /> salvaged and replaced should be capable of growing vegetation <br /> consistent with what is there now. The average depth of topsoil <br /> on the site according to the NRCS report is 0 to 5 inches deep. <br /> Using 3. 0 inches as the average we calculate there should be a <br /> minimum of 8, 070 YD3 of growth medium available for resoiling the <br /> disturbed area. In addition, there is from 0 inches to 9 feet of <br /> overburden on most of the site. Much of this overburden will be <br /> retained and used to rebuild slopes . If needed, it could be <br /> transformed into growth medium to supplement topsoil needs . Be <br /> assured that enough growth medium will be retained on the site to <br /> assure reclamation and revegetation is successful. The topsoil <br /> and overburden stockpiles will be located around the excavation <br /> (their approximate locations are shown on the MINING PLAN MAP) to <br /> reduce the haul distances when reclamation starts. If the soil <br /> and overburden stockpiles remain undisturbed for more than one <br /> year a cover crop of Western Wheatgrass at a rate of 2 pounds- <br /> pls/100 sq-ft will be planted on them. <br /> MINING PLAN <br /> Of the 81 . 40 acres ± in the permit area a maximum of 76. 66 <br /> acres ± will be disturbed by the mining operation. Presented in <br /> this mining plan are detail plans for developing the mine under <br /> 2 different options . The first will be to create slopes around <br /> the site as shown on the EXHIBIT F-1 -RECLAMATION PLAN MAP. This <br /> option leaves the Perrino House Area and the School House Area as <br /> undisturbed islands in the mining area with 3h to lv slopes on <br /> the 3 mined sides of the islands. Option 2 would remove the <br /> Perrino House Area and the School House Area, and leaves a 3h to <br /> 1 v slope along the north side of the permit as shown on the <br /> ExHIBITF-2-RECLAMATION PLAN MAP. The existing slope along the north <br /> line will not be disturbed. A 25 foot setback will be maintained <br /> along the powerline in addition to the 25 feet side ROW so mining <br /> will not take place within 50 feet for the power poles . <br /> The method of mining discussed below will fit each option <br /> unless otherwise stated. Please use the RECLAMATION PLAN MAPS during <br /> review of the following text for the areas discussed. They show <br /> 8(Revised 8/12/21) <br />
