EXHIBIT G WATER INFORMATION <br /> 1. General <br /> The site is a dry alluvial terrace of Hard Scrabble Creek. It is currently rangeland. Portions of the <br /> site are located within the 100-YR floodplain, as identified by FEMA.No fill above the original <br /> grade is planned by this operation. The creation of an excavation within the floodplain will act as <br /> a hydrologic sink in the event of the flood, likely reducing flooding downstream. <br /> Surface water flows drain naturally from the east to the west towards Hard Scrabble Creek. <br /> During mining, runoff that occurs within the disturbed area will all be routed to the active mining <br /> pit. This is accomplished by using elevation barriers such as the pit highwalls and the topsoil <br /> berm/windrows on the pit perimeter. No sediment will be allowed to leave the site and cloud any <br /> downstream waters. The site will not affect existing water rights, as the pit will not expose <br /> groundwater and will not store stormwater for more than 72 hours. After reclamation, <br /> stormwater encountered in the mining 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. 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 Yevoli Cobblestone Pit. This well was permitted for domestic use <br /> by Charles Gutierrez and Jack Beedle. This well (252214) reaches a depth of 105 feet, and thus <br /> will not be affected by mining activities, since those stop at a depth of 25 feet. Additionally, <br /> there will be no groundwater exposure as part of this operation, and therefore there is no <br /> dewatering on site. <br /> Yevoli Cobblestone Pit Grey,Ix.sck,and �ssncialrs PI I <br /> August 2018 G-1 <br />
