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 in the area flows to the north with ultimate drainage to the northeast, 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 at the site will <br /> 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 <br /> within 600 feet of the mining pits of the Base Products Gravel Pit#2. These three wells are <br /> permitted by New Castle and are to the southeast of the Base Products Pit#2, as shown on <br /> Map C-1. Depth to groundwater of each well are as follows: 254749-49 feet completed, static <br /> water depth 24 feet-5,780 feet in elevation, constructed 2004 for monitoring and sampling <br /> (shale at 36 feet); 254684-62 feet completed, static water depth 51 feet-5,750 feet in <br /> elevation, constructed 2004 for monitoring and sampling (shale at 54 feet); and 254683-60 <br /> feet completed, no water was encountered during well construction, current surface elevation <br /> -5750 feet, constructed 2004 for monitoring and sampling (shale not encountered). <br /> The maximum mining depth is to 5700 feet in elevation. Based on landowner experience, the <br /> water source for the above-mentioned wells does infiltrate to the site. The three wells above <br /> show shallow water depths, however, this phenomenon is likely from infiltration from irrigation <br /> wells because the alluvial aquifer of the Uncompahgre River is significantly below the levels of <br /> these wells. <br /> Base Products Gravel Pit 2 <br /> April 2022 G'1 Lewicki&Associates <br />
