RECLAMATION PLAN EXHIBIT E (CONT.) <br />times. When mining resumes the highwall mining method will again <br />be used. <br />Since the slopes around the perimeter of the mined area will <br />be mined to their final rates, only minor amounts of slope work <br />will be necessary when mining ends. This will also insure, that <br />if mining ceases before the resource is exhausted, only a minor <br />amount of work would have to be done to finish reclamation on the <br />disturbed area. <br />The placement of the soil stockpiles around the perimeter of <br />the mined area or direct placement on the final slopes as strip- <br />ping takes place will also reduce the cost to reclaim the site if <br />mining ended prematurely. By using this method the topsoil only <br />has to be handled once and reclamation will run concurrent with <br />mining. Placing the topsoil where it will be needed for reclama- <br />tion will reduce the distance it has to be moved. <br />There are sufficient amounts of topsoil so the mined area <br />can be resoiled to an average depth of 10 inches. Remember that <br />this will only be done IF the material is available. We will use <br />the available topsoil salvaged from the stripping process and <br />will not haul additional soils onto the site for revegetation. <br />This is especially true on the floor of the old mining area where <br />no topsoil exists at this time. Some growth medium was stored on <br />the east side of the old mine area and that will be used for the <br />old mine area. Existing soils in place have been capable of <br />producing a good cover of native grasses suitable for grazing <br />purposes when not abused. EXHIBITI/J describes the current cover in <br />the terms of yearly production typically found on the soils found <br />on the site. Our site specific investigations suggest it is <br />close to the NRCS report numbers which will be used as background <br />information as reclamation progresses. One sure way of determin- <br />ing reclamation success is to compare the reclaimed areas with <br />surrounding undisturbed rangeland areas. If they match, the <br />revegetation is successful. <br />As outlined in the MININGPLAN, 36.78 acres ± of the permitted <br />area will be disturbed as a result of mining. Of this area 5.82 <br />acres is in the pre-mined area and the remaining 30.96 acres is <br />in the new area. Since there are no stages in the permit, <br />reclamation will run concurrent with mining. As mining pro- <br />gresses across the property some parts of the property will <br />remain undisturbed while other areas will be stripped, mined, and <br />either partially reclaimed or totally reclaimed. The MININGPLANMAP <br />-EXHIBITGI shows how the pit will look when approximately 45% is <br />14
