EXHIBIT G WATER INFORMATION <br /> This exhibit discusses the water quality monitoring plan developed to protect the integrity of <br /> local surface and groundwater quality. Elam is committed to protecting the prevailing <br /> hydrological balance and water quality at the site. <br /> 1. General <br /> The entire 23 1/4 West Pit affected area is located over 300 feet from the Colorado River, east of <br /> the Wilsea Drain. The disturbance area of the site is over 400 feet from the river; a small finger <br /> of affected area that is not to be disturbed extends to the southwest towards the river and <br /> floodway. Groundwater is roughly seven feet below the natural grade and is the alluivial aquifer <br /> of the Colorado River. The 100-YR FEMA3 floodplain encompasses the entire mining area. The <br /> floodway is 30 feet to the southwest of the disturbance area, close to the river. <br /> 2. Water Quality Protection <br /> The main concerns regarding water quality are potential impacts to surface or groundwaters from <br /> sediment,hydraulic fluids, or diesel fuel. Sediment will be controlled through the use of <br /> stormwater retention within the disturbance area throughout the life of the mine. All stormwater <br /> runoff and surface water flows from the local drainage area will be collected with control <br /> measures built around the site. This includes mine slopes and the stormwater berms. This will <br /> contain all sediment within the site and prevent its unattended discharge from the site. Hydraulic <br /> fluids and diesel fuels will be contained within any vehicles through the use of best practices of <br /> maintenance and regular inspections of vehicles,hydraulic lines, and any other potential sources <br /> of spills. Diesel is proposed to be stored on-site in double walled tanks,the additional wall acting <br /> as the required secondary containment. Furthermore,the tanks will be located away from <br /> exposed ground water. Inadvertent spills that occur during fueling or refilling operations will be <br /> cleaned up immediately utilizing spill kits located adjacent to all fueling areas. <br /> s Federal Emergency Management Agency <br /> 23 114 West <br /> July 2020 G-2 Greg Lamicki and Asmciatrs PI,L(' <br />
