Banks and Gesso. LLC <br />Earthmovino Operations and Maximum Disturbance <br />Vegetation and plant growth medium will be cleared and salvaged, respectively, prior to <br />mining. Topsoil, as available, will be used to construct 6-foot screening berms in <br />selected locations. <br />Standard equipment, including excavators, backhoes, loaders, and haul trucks will be <br />used in earthmoving operations at the Grand River Park Project. <br />Site disturbance will be minimized through the phasing plan, as described above, and <br />concurrent reclamation. Based on the work methods and schedule, the operator will <br />commit to disturbance of no more than 60 acres at any one time. <br />Dewaterino <br />The Grand River Park Project mining areas will be equipped with pumps to allow for dry- <br />mining. Water impacts associated with dry-mining are discussed in Exhibit G. <br />With the active mine areas dry, a variety of mining equipment will have access to the pit <br />floor. Given only partial dewatering, mining methods will be accordingly adapted to <br />accommodate wet working areas and wet material. Should the pit floor remain wet, an <br />excavator would remain at the pre-mining ground level and progressively work the <br />mining footprint backward. In this scenario, wet pit run would be temporarily placed on <br />the immediately adjacent existing ground surface to allow for moisture to run off and <br />evaporate. After sufficient drying time, a loader would remove pit run materials and the <br />temporary drying areas would then be subject to recovery of aggregates. This <br />progressive, two-stage mining method would be used in circumstances where <br />groundwater pumping is limited due to on- or off-site constraints. <br />This plan is intended to accommodate the continued delivery of water from the Last <br />Chance Ditch and the Rising Sun Ditch to users north of the mining area(s). Ditch <br />laterals are maintained under the Exhibit C Mining Plan and may be adjusted or <br />eliminated as appropriate to provide necessary water conveyance. <br />Grand River Park Project Uo021 <br />Silt Sand & Gravel LLC 10 May 2006 <br />
