Exhibit C <br />(e) Major Components of the mining operation. <br />The haul road through the permitted site and the area of borrow <br />excavation are the only components of the mining operation. <br />Once the topsoil has been salvaged and the haul road <br />constructed, excavation/hauling operations will begin. The <br />borrow material will be excavated using large backhoeslloaders <br />and placed directly into truck -trailer hauling units for <br />transporting to the job site on WCR 49 immediately next to the <br />borrow site <br />Excavation of the borrow materials will proceed in a west to <br />east direction. The side slopes of the final excavation are to be <br />at a maximum gradient of 3:1 (horizontal to vertical). As the <br />borrow material is being removed, the excavation in the area of <br />the final slopes will be done at this 3:1 gradient. <br />(f) Dimensions of land disturbance. <br />The area of land disturbance is rectangular in configuration. <br />The dimensions of the disturbed area are roughly 600 feet x <br />580 feet, this includes the area of the topsoil berm at the top of <br />the excavation slopes. These dimensions result in an area of <br />8.0 acres. <br />(g) Haul road dimensions. <br />An existing haul road will be used to get to our permitted <br />boundary. <br />(h) Water use. <br />The only water to be used in conjunction with the borrow site <br />operation, will be water applied to the on-site roads for dust <br />control. Approximately 8,000 gallons of water per day will be <br />used for dust control. The source of this supply will be the same <br />as the project's water source along Weld County Road 49 <br />Page 2 of 4 <br />
