Including a wash plant was covered in a prior Technical Revision and the only aspect that has <br /> changed over the years is the source of the water. The source of the water for this wash plant will be <br /> purchased water from the City of Colorado Springs that is associated with the Nixon Power Plant <br /> immediately to the south of the operation. A pipeline that was approved by the City of Colorado <br /> Springs has been installed from the power plant to the initial location of the wash plant and that <br /> waterline is located adjacent to the Colorado Springs power lines that run from the power plant <br /> northward along the eastern side of the Fountain Pit permit area. The water is pumped northward to <br /> where it makes a right angle turn westward and feeds the water supply pond and the wash plant. The <br /> water is recycled so the only loss from the system is evaporation and the water leaves in the product. <br /> So, once the system is charged the only water needed from the city is to replace what was lost to the <br /> product and to evaporation. <br /> A copy of the water lease from Colorado Springs Utility is contained in the included letter of <br /> July 22, 2020 from Abdullah Javed, E.I. of the Applegate Group to Melissa van der Poet of the <br /> Colorado Division of Water Resources. This letter pertains to an amendment to the SWSP for this <br /> operation. The letter of December 3, 2020 already in the Division's permit files in the Hydrology <br /> category contains the approval of this amendment. <br /> The water from the wash plant is fed back to a two stage settling pond system to remove <br /> sediment from the water before it is reused. Thus the sediment ponds must be periodically cleaned out <br /> of accumulated fine material washed off the gravel. This sediment can then be allowed to drain and <br /> dry. On occasion a customer may wish to purchase this very fine material, but usually it is considered <br /> waste and can be used to blend with overburden or other coarse material to create a fine growth <br /> medium that can be used on the pit floor for reclamation. <br /> This material is NOT suitable for slope reclamation as it tends to retain a considerable amount <br /> of water and on a slope the extra mass when wet can cause slumping of the 3:1 or steeper slope. (It <br /> could be used on a much more gradual slope,however.) These fines are mostly clay and fine silt <br /> particles. No flocculents will be used to settle the sediment. <br /> Product Stockpiles <br /> As the product is produced stockpiles are usually created at the location where the product <br /> exits the conveyor belt from the plant where that product is produced. However, some more coarse <br /> product is produced by other equipment and that material is stockpiled elsewhere in the vicinity of the <br /> plant. Some seams within the deposit contain larger stones that need to be separated from the finer <br /> material which is what some customers want. Although large quantities of these larger rocks are rarely <br /> encountered, small amounts of this rock is also available for purchase. <br /> Fountain Pit Technical Revision#3 - June 2022 M-1982-155 Mining Plan Page 17 of 22 <br />
