7.2. Groundwater — Reclamation <br /> Permanent water storage reservoirs will be left behind, as can be seen on Map F-1. There will <br /> be no groundwater consumptive use in reclamation. <br /> 7.3. Groundwater — Slurry Wall Impact <br /> The installation of a slurry wall within the alluvial aquifer of the South Platte River creates two <br /> main potential impacts to the aquifer: the creation of local groundwater shadows or mounding <br /> that damage neighboring structures or property and the potential exacerbation of regional <br /> groundwater impacts. These impacts however are anticipated to be very localized and not <br /> impact nearby wells. Additionally, a french drain will be constructed up-gradient of the slurry <br /> walls to control groundwater mounding. The drain will direct abnormally high water to an <br /> infiltration gallery in the permit area that will return the water to the groundwater aquifer and <br /> river. <br /> 8. Water Related Permits <br /> The operator is applying for all necessary permits that have not already been acquired for water <br /> handling at the Evans Pit. This includes a discharge permit with the Colorado Department of <br /> Public Health and Environment and a gravel well permit for initial dewatering of each pod with <br /> the Colorado Division of Water Resources. <br /> 9. Water Consumption and Source <br /> Water for dust control will be the primary consumptive use at the Evans Mining Resource site. <br /> Water will be purchased from a local source during operations for consumptive uses. No <br /> ongoing water consumptive use exists in reclamation, since the water storage pod is lined. This <br /> water will be sourced from a freshwater pond in the processing area. This pond will be covered <br /> by a gravel well permit. Table G-5 summarizes the estimated water consumption for the <br /> operation throughout the year. <br /> Evans Mining Resource <br /> October 2024 G-6 101 Lewicki&Associates <br />
