Exhibit C <br /> (e) Major Components of the mining operation. <br /> The entrance and exit for the permitted site and the area of <br /> borrow excavation are the only components of the mining <br /> operation. <br /> Once the topsoil has been salvaged and the entrance and exit <br /> is constructed, excavation/hauling operations will begin. The <br /> borrow material will be excavated using large backhoes/loaders <br /> and placed directly into truck-trailer hauling units for <br /> transporting to the job site on Lemay Avenue. <br /> Excavation of the borrow materials will proceed in an east to <br /> west direction. The side slopes of the final excavation are to be <br /> at a maximum gradient of 4:1 (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 4:1 gradient. <br /> (f) Dimensions of land disturbance. <br /> The area of land disturbance is in a trapezoid configuration. <br /> The average width of the trapezoid is 780 feet running east to <br /> west and average length is 890 feet running north to south. <br /> These dimensions result in an area of 15.5 acres of active <br /> mining area. <br /> (g) 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 Lemay Avenue in Fort <br /> Collins. <br /> (h)Groundwater/surface water occurrence or disturbance. <br /> Page 2 of 4 <br />
