EXHIBIT G WATER INFORMATION <br /> 1. General <br /> Map C-1 shows the location of all identified streams, creeks, ponds, or other water courses on the <br /> surface. The only known aquifer in the area is the alluvial aquifer of the East Fork of the Arkansas <br /> River. The river runs along the north side of the proposed mining operations. <br /> 2. Surface Water <br /> The proposed disturbed areas of each pit will drain internally. No stormwater will be allowed to <br /> leave disturbed areas and flow offsite. Due to the permeable nature of the alluvium and the high <br /> altitude of the site (>10,000 ft), it is anticipated that all surface water from storms will infiltrate or <br /> evaporate. <br /> The 100-YR 24-HR storm event for this area is 3.15 inches.3 Ground water is at least 30 feet below <br /> the surface, and will provide sufficient storage space in each pit to contain all stormwater. Perimeter <br /> berms around the processing area will be maintained during mining. These berms will be at least <br /> two feet tall with 2H:1 V sideslopes. Berms will be made of topsoil and will be vegetated upon <br /> construction. See Map C-2 for their location. <br /> A Colorado Department of Public Health and Environment stormwater discharge permit will not be <br /> necessary since as discharges will leave the site. <br /> 3. Groundwater <br /> Ground water will not be exposed until a substitute water supply plan or water augmentation plan is <br /> in place from the Colorado Division of Water Resources. This application shows mining of sub- <br /> water table material and the presence of post-mining lakes as intended by the Operator. However, <br /> no ground water exposure will take place until the appropriate water source permits <br /> (SWSP/augmentation plan) are in place. Until that time, excavation will remain at least two feet <br /> s National Oceanic and Atmospheric Administration 14 Point Precipitation Frequency Estimates for Colorado; <br /> https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=co <br /> Birdseye Pit Gr",�Lewicki and As%miato,PLl C <br /> June 2019 G-1 <br />
