Grading and Backfilling <br /> The mining will leave no highwalls on the property. No acid forming or toxic materials are used <br /> in the mining. There will be no auger holes, adits or shafts left on the property. The operator <br /> will utilize concurrent reclamation in this operation. <br /> The grading will result in a smooth ground surface on the eastern portions of the property <br /> planned for pasture land, and in the proposed shoreline for the reservoir. The perimeter of the <br /> reservior will be graded and revegetated to blend with the existing topography. Disturbance to <br /> areas outside the excavation limits will be minimized to the natural vegetation conditions. The <br /> grading will be completed with effort taken to minimize the amount of ground surface disturbed <br /> while matching existing grades. Care will be taken to preserve existing trees and shrubs. <br /> The shoreline will be backfilled to a 3H:1V maximum sideslope and will be concurrent with <br /> mining, as material becomes available. <br /> Topsoil <br /> An abundance of lime soils and overburden is available for the backfilling and grading of the <br /> eastern area. The reclamation operation will utilize topsoil and overburden stripped on-site. <br /> The western half of the site contains 6 to 8 feet of lime soils.and overburden and topsoil that will <br /> be stockpiled on-site. This material is from Great Western Sugar Company's abandoned <br /> sediment settling areas. Sediment washed from sugar beets was deposited in these settling <br /> basins. The sediment has been tested and is safe. Attachment E2 is a letter from the Larimer <br /> County Health Department that states this. Attachment E3 is lab results from test done on the <br /> sediment. <br /> Water <br /> Disturbance of the area will be done to minimize the effect on the prevailing hydrologic balance <br /> as follows: <br /> a) The operator shall comply with all applicable Colorado water laws. <br /> b) The operator shall comply with all applicable Federal and State water quality laws and <br /> regulations. <br /> c) The operator shall comply with all Federal and State requirements for dredge and fill. <br /> d) The operator shall regrade all sediment or siltation structures after mining is completed. <br /> The operation will] not affect groundwater quality on or off site. The operator will comply with <br /> all state groundwater quality standards. <br /> Due to the absence of any pollutants used or generated in this mining operation, groundwater <br /> quality monitoring is not proposed for this operation. <br />
