._ <br />MINING PLAN <br />E%HIBIT D (CONT) <br />permit boundary as practical. This will serve to limit impacts <br />to surrounding land uses. <br />At some time it maybe necessary to mine some of the area as <br />dry pits. To do this we will excavate dewatering trenches around <br />the area in question and install a pump to dry the gravel out. <br />Where we are dry mining the material will either be moved using <br />scrapers, large haul trucks or conveyor systems to the processing <br />plant. <br />No matter what method of mining we use, additional area will <br />be stripped ahead of the mine face and the topsoil needed for <br />reclamation will be stockpiled along the setbacks around the mine <br />area. The rest will be sold or mixed with gravel to make various <br />grades of product. The salvaged topsoil will be used when <br />reclamation begins in the area where it was removed. It will be <br />needed for recoiling slopes and other areas where we have to <br />establish vegetation. By limiting the amount of area stripped at <br />any one time we will lessen the visual impacts of the mining <br />operation as much as possible. Please see MAP EXHIBIT F - <br />RECLAMATION PLAN MAP for the approximate shape of the lakes <br />when reclamation is complete. <br />The amount of land disturbed at one time will be limited to <br />that area needed for processing, batching and stockpiles (Plant <br />Site), 15.00 acres ±; stri p~pre-mining area, 10.00 acres ± and <br />no more t an 10.00 acres ± or paTtia3--ly_ reclainie~ area will need <br />reclamation.--This means that there will be 35.00 acres ± or less <br />ne~tl"ing sosome type of reclamation at any one time. Note, that any <br />area covered by water needs no reclamation except in a narrow <br />band below water, around the lake shore, where slopes have to be <br />established to no greater than 3h to lv according to State Law. <br />Th__. e.Sho~Area_is shared with the agricult~ al operatian_and_is~ <br />not included in_the_bond_since.l'~ wi71 remain when mining ends. <br />The Plant Site area will be the last area to be mined as the <br />reserves are exhausted. It may remain in the place shown on the <br />map, or moved to the next mining area if it is not practical to <br />haul raw material from the outer areas as mining progresses. <br />Since a Plant Site will be utilized throughout the life of the <br />mine it will accommodate the processing equipment and may serve <br />as a site for auxiliary uses. These uses may include an asphalt <br />batch plant, a concrete batch plant and/or a concrete casting <br />facility. <br />As mining progresses around the property the bank slopes <br />will be created in two stages. When a dredge is used the native <br />materials tend to sluff off the banks and assume an angle of /I <br />repose of 2=h to lv. This happens because the material in this ~ <br />area is unconsolidated and vertical slopes can not be maintained <br />as mining occurs. This means that to maintain a setback of 100 <br />feet when the gravel is 60 feet thick the mining line has be no ~~ ~ <br />less than 75 feet inside the setback lines to allow for the <br />sloughing. The second step will be to cover these natural slopes <br />with some of the material being mine. This will establish the <br />slopes to the prescribed 3h to lv. A dredge makes this fairly <br />simple since the material is contained in solution (water) and <br />8 <br />
