8.2 Groundwater—Reclamation <br /> Once mining and reclamation are completed on site,the pit pumping will cease. Permanent <br /> groundwater lakes will form as shown on Map F-1. Permanent lakes will generate evaporative <br /> losses of groundwater. However, as the Colorado River in this area is under-appropratied, no <br /> augmentation plan or substitute water supply plan is necessary. <br /> 9. Water Associated Permits <br /> Elam is applying for all necessary permits for water handling at 23 '/4 West Pit. This includes a <br /> Colorado Department of Public Health and Environment discharge permit and a Colorado <br /> Division of Water Resources gravel well permit. <br /> 10. Water Consumption and Sources for the Operation <br /> Water for dust control will be the primary consumptive use onsite during mining. Wash plant <br /> water usage is also figured into this operation. A small amount of evaporation is assumed with <br /> the sediment pond onsite. Table G-1 shows a breakdown of estimate water consumption for the <br /> operation during mining and reclamation. <br /> Water is needed for dust control during crushing/screening, dust control on disturbed areas and <br /> roads, and water consumption due to evaporation in the sediment ponds. <br /> 23 114 West <br /> October 2020 G-8 �' <br />
