EXHIBIT G -Water Information <br /> a) Test pitting performed at the Koskie site shows that groundwater is deeper than approximately 15 feet; <br /> therefore, it is anticipated that no groundwater will be encountered at the site. In order to avoid exposing <br /> groundwater and to facilitate surface water drainage out of the pit,the pit excavation will not be deeper than <br /> approximately 15'feet which will be slightly higher than the bench terrace located directly east of and <br /> adjacent to the Koskie site. Weld County will stay approximately 2 feet above the groundwater elevation in <br /> order to prevent the exposure of groundwater. According to information obtained from the State Engineer's <br /> Office,the Koskie site is not located within a designated groundwater basin. <br /> b) There are no FEMA-designated floodplains or floodways on the portion of the Koskie site which is proposed <br /> for mining activities. <br /> c) There are no existing or planned surface water impoundments at the Koskie site. Water needs for gravel <br /> mining and processing operations are expected to minimal;water for dust control can be obtained and <br /> hauled from County-owned wells which have been permitted for such purposes. It is anticipated that less <br /> than 4,000 gallons of water per year will be necessary for dust control purposes. No water is anticipated to <br /> be used during the mining or reclamation phases. <br /> d) There are no irrigation structures on the Koskie property. <br /> e) There is one well, Well Permit No. 293366,which is located on the property but outside of the mine permit <br /> area. According to the well permit,the well is used for livestock watering and has a pumping rate of 2 <br /> gallons per minute(gpm). The well is pumped via a windmill and the water is stored in a water tank. <br /> Mining is not expected to impact the well or the water supply because groundwater will not be intercepted. <br /> Furthermore,the well and windmill will be covered under a structures agreement. <br /> f) Since groundwat r will not be encountered,there will be no need for dewatering the site. Any stormwater <br /> that falls on the s�te will be directed east along its historical flow path towards Lone Tree Creek. A CDPHE <br /> Stormwater Construction permit will be obtained for this site and best management practices will prevent the <br /> migration of sediment or other pollutants off-site. <br /> g) The mining operation is not expected to impound stormwater. The mining area will be bermed to divert <br /> stormwater around the permit area and prevent any stormwater from running into the pit. Any stormwater <br /> falling directly into the pit will be diverted and released back to the stream within 72 hours in order to <br /> comply with State of Colorado water law. <br /> M:\Mining\Koskie\DRMS Application\Koskie Application Exhibits 7-9-14.doc <br /> 7/9/2014 <br />
