EXHIBIT G WATER INFORMATION <br /> 1. General <br /> The site is in the upper alluvial terrace of the Eagle River. The river is roughly 700 feet to the <br /> north at its closest. The site is currently rangeland.None of the site is within area floodplains. <br /> The Oldcastle gravel pit known as the Gypsum Ranch Pit and US-6 are between the river and the <br /> Tower Pit. <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. All water from the disturbed area will drain to the bermed active pit and cannot leave the <br /> site. Fuel leakage is also not a problem since all fuel tanks on site will have secondary <br /> containment as well as strict procedures for spill prevention and control. <br /> According to searches on the Division of Water Resources database, there is one well within 600 <br /> feet of the mining pits of the Tower Pit. It is a well located on the Eagle County Regional Airport <br /> property. This well (015023-F) reaches a depth of 92 feet, and thus will not be affected by <br /> mining activities, since those stop at a depth of 60 feet. Additionally,there will be no <br /> groundwater exposure as part of this operation, and therefore there is no dewatering on site. <br /> Tower Pit X(.ek IcN cf and 1sxK Hti•.1'1,1 <br /> October 2018 G-1 <br />
