<br /> <br />Banks and Gesso, LLC <br />Initial mining operations will include stripping; excavation of the dewatering trenches, <br />sedimentation pond and sump areas; and developing the process water ponds. After <br />the topsoil and overburden has been stripped, raw material will be excavated utilizing <br />front-end loaders. Material may be loaded on a field conveyor in the mining area and <br />conveyed back to the processing plant. Some materials may be excavated with <br />scrapers or loaded into off-road haul trucks for transport to the plant site. Material may <br />also be pushed up with a bulldozer for handling by front-end loaders. <br />Earthmovinp Oaerations -Rule 6.4.4 (b) <br />Earthmoving operations will begin with the grubbing of agricultural vegetation. Stripped <br />topsoil and grubbed agricultural vegetation will initially be stored in stockpiles for later <br />use in reclamation. Visual screening berms will be selectively constructed on the <br />perimeter of the property and will be planted with temporary seed mixes identified in <br />Exhibit E. During subsequent stripping operations, overburden from one area may be <br />placed directly, to near final grade, in other areas being concurrently reclaimed. <br />An average depth of approximately 7' of overburden exists over the entire area proposed <br />of mining. This is underlain by an average of approximately 40' of sand and gravel. <br />Thus the total depth of excavation throughout the property will be approximately 47 feet. <br />Water Diversions and Impoundments -Rule 6.4.4 (c) <br />Stormwater from all areas of surface disturbance will be directed by grading and shallow <br />ditches toward the mine's dewatering systems. A CDPS permit will be obtained from the <br />Colorado Department of Public Health and Environment for the dewatering operations. <br />Aggregate processing water will be separate from the de-watering and stormwater <br />systems. With evaporation and product moisture losses, there should be no need to <br />discharge processing water. Moreover, some de-watering discharges will be diverted <br />back to the processing water system. During mining operations the silt ponds will be <br />located in the southeastern portion of the property adjacent to the plant area. The ponds <br />will be maintained below existing grades so that any precipitation will be retained in this <br />area. <br />Nix Property Sand and Gravel Mine.CDMG.112 Permit 20075.WD <br />Owens Brothers Concrete Company May 2001 <br />7 <br />
