EXHIBIT G <br /> WATER INFORMATION <br /> Based on the geotechnical report prepared by Terracon on 2/25/2020, groundwater occurs at an average <br /> elevation of 5,543 feet. The actual depth to groundwater varies throughout the site and, as outlined in the <br /> mining plan,the bottom depth of the mine will stay at least 2' above the groundwater elevation at all times. <br /> In the event that groundwater rises enough during the wet season to be exposed, the exposed areas will <br /> immediately be buried to 2' of coverage and mining in those locations will cease immediately. Therefore, <br /> no groundwater will be exposed at the site. <br /> Water usage for this site will consist of 20,000 gallons per day for dust control. This water will be trucked <br /> from offsite as needed.Additional water needed will be drinking water for mine workers that will be brought <br /> in from offsite as bottled water. <br /> A National Pollution Discharge Elimination System (NPDES) permit is not required for this site as there <br /> are no chemicals in use and there is no discharge of water or other fluids to the environment. The mined <br /> area will be graded such that all stormwater discharge will be contained to the pit where it will seep back <br /> into the ground. <br /> When it comes to protecting the groundwater system from potential spills of fuel,oil,lubricants,etc.,Kiewit <br /> takes environmental compliance very seriously on all of its jobs and fixed facilities. Kiewit commits to <br /> fully comply with the EPA Spill Prevention Control and Countermeasure(SPCC)regulations(40 CRF 112) <br /> for this mine. In addition to compliance with these requirements,Kiewit has a written Environmental Policy <br /> and Program and requires all to follow this program. As part of our commitment to the environmental <br /> compliance,we will comply with all applicable environmental permits and regulations. <br /> Some of the Best Management Practices(BMPs)in the site-specific SPCC plan and Kiewit Environmental <br /> Policy and Program include: <br /> • The onsite lube truck will be stored in a large concrete pan that has curbs on all sides when not in <br /> use to contain possible spills. <br /> • On site fuel tanks shall be double walled tanks or have secondary containment around them. <br /> • The facility would have spill kits located near where equipment would be working or maintained. <br /> • The equipment used on site will be kept in good working order. Daily equipment checks are <br /> completed by operators and the equipment is maintained regularly by Kiewit's own fleet <br /> mechanics. <br /> • Regular environmental inspections of the site by the mine manager and Kiewit environmental staff <br /> to ensure environmental compliance is adhered to by all workers. <br /> During mining, all cells will be internally graded in order to ensure run-off from the disturbed area, <br /> stockpiles, and operating surfaces do not enter the surface stream system. During final reclamation of the <br /> site,the mined areas will be graded and sloped to drain naturally to Lone Tree Creek as shown in Exhibit <br /> F. <br /> The groundwater system will not be impacted by the mining operation. No dewatering will occur. <br /> Two small ponds exist within mining cell 9 and mining cell 12. According to data available from the <br /> Colorado Division of Water Resources, there are no water rights or well permits associated with these <br /> Kiewit <br /> DRMS 112 Permit Application <br /> Page G-1 <br />
