EXHIBIT G WATER INFORMATION <br /> 1. General <br /> Prior to mining, the site was a mixture of irrigated agriculture fields and rangeland. Some <br /> portions of the previously permitted property have naturally occurring oxbows and other low <br /> topography that facilitate riparian habitats. The pit is immediately west of the Mexican Gulch <br /> ditch which is directly adjacent to the Uncompahgre River to the east. The site is well outside of <br /> the FEMA identified floodplain. <br /> Surface water flows in the new area to the southeast with ultimate drainage to the east, off the <br /> terrace, towards the Uncompahgre River. However, surface water flows are extremely unlikely <br /> and surface waters are expected to infiltrate prior to accumulating and leaving the site. No <br /> sediment will be allowed to leave the site and cloud any downstream waters. The site will not <br /> affect existing water rights, since the pit will not expose groundwater and will not store <br /> stormwater for more than 72 hours. After reclamation, stormwater encountered in the mining <br /> area will continue to infiltrate or evaporate. <br /> The two principal ways that the gravel pit could affect the water quality of the area downstream <br /> are a) through poor sediment control within the site causing increased sedimentation <br /> downstream, and b) by fuel leakage from a ruptured tank. Water that is encountered in the pit <br /> will not be released from the site. The only water that will be found within the disturbed area is <br /> stormwater runoff and water hauled to the mining area and used in processing and for dust <br /> control. Once excavation of new areas begins, all water from the disturbed area will drain to the <br /> bermed pit and cannot leave the site. Fuel leakage is also not a problem since all fuel tanks on <br /> site will have secondary containment as well as strict SPCC Plan procedures for spill prevention <br /> and control. <br /> According to searches on the Division of Water Resources database, there are three wells within <br /> 600 feet of the mining pits of the Base Products Gravel Pit#1. These three wells are permitted by <br /> New Castle and are to the southeast of the Base Products Pit#1, as shown on Map C-1. Depth to <br /> groundwater of each well are as follows: 254749—49 feet completed, static water depth 24 feet <br /> —5780 feet in elevation, constructed 2004 for monitoring and sampling (shale at 36 feet); 254684 <br /> Base Products Gravel Pit 41 <br /> February 2018 G-1 <br />
