<br />C~erational History of th Facility <br />The site was permitted in 1980, but actual mining did not <br />start until the mid-1980's. The mining should be <br />completed between 1995 and 2,000. Below is the narrative <br />and typical cross-section taken from the approved plan. <br />After mining the land will be reclaimed by refilling the <br />property with reject material and clean inert fill on top of <br />which will be placed a minimum of 6" of topsoil. Therefore <br />the disturbed area that will reveAetaced is the entire <br />property, or 42.75 acres. Once again a row of drought <br />resistant trees on 50' approximate centers will be placed <br />along U.S.85. <br />Except for the 10' setback areas along the abutting roads <br />that von't be mined, reject material and clean inert fill <br />material will be placed to approximately 6" below final <br />elevations. The clean inert fill will primarily be obtained <br />from the operator's other company, Siegrist Construction <br />Company, from road projects. The debris is considered inert <br />by the State Health Department and does not require a <br />Certificate of Designation (See Exhibit M - Pages 48-50). <br />The operator may also allow other contractors to dispose of <br />such debris, but the operation will not be open to the <br />general public. <br />On top of the clean fill and reject material will be placed a <br />minimum of 6" of topsoil that will then be seeded. Any <br />compacted areas, such as the scale area, will be ripped prior <br />Co replacement of topsoil and seeding. The property will be <br />gently sloped to alloy drainage to Nome Street and 132nd <br />Avenue. This area has already been subdivided into lots and <br />those lots are shown on Exhibit F, Reclamation Plan MaD, but <br />the final land use is not known. The property would be <br />suitable for residential, commercial, or some industrial <br />uses. Which will occur will be left to future decisions. <br />As with the A Phases in regards to topsoil depths, it should <br />be noted chat the thickness specified will be depths replaced <br />on prepared ground surface. Some consolidation of the medium <br />may also be expected to occur due to the equipment replacing <br />_ __ the soil and to natural processes during precipitation <br />--~ events. _ <br />" TOPSOIL MINIMU M~ L ~O <br />AREA TO BE FILLED w/SPOILS @ ~ CLEAN <br />FILL ~ <br />WATER LINE / ~ / <br />AREA WNICM MAY <br />BE EXCAVATED @ <br />BACK FLLED W/SPOIL` <br />8 CLEAN FILL. <br />
