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. The permittee is committed to protecting the prevailing <br /> hydrological balance and water quality at the site. <br /> 1. General <br /> There are no natural waterways within the Mystic Soil affected area. Groundwater is at least 80 <br /> inches below the natural grade. Lateral Forty-seven of the Farmers Union Canal borders the <br /> north side of the permit area. <br /> 2. Water Quality Protection <br /> The main concerns regarding water quality are potential impacts to Lateral Forty-seven of the <br /> Farmers Union Canal and the groundwater aquifer from sediment,hydraulic fluids, or diesel fuel. <br /> Sediment will be controlled through the use of stormwater retention within the disturbance area <br /> throughout the life of the mine. All stormwater runoff and surface water flows from the local <br /> drainage area will be collected with control measures built around the site. This includes mine <br /> slopes and the stormwater berms. This will contain all sediment within the site and prevent its <br /> unattended discharge from the site. Hydraulic fluids and diesel fuels will be contained within any <br /> vehicles through the use of best practices of maintenance and regular inspections of vehicles, <br /> hydraulic lines, and any other potential sources of spills. Diesel is proposed to be stored on-site <br /> in one 500 gallon double walled tank,the additional wall acting as the required secondary <br /> containment. Inadvertent spills that occur during fueling or refilling operations will be cleaned <br /> up immediately utilizing spill kits located adjacent to all fueling areas. A set back of 500 feet <br /> from Lateral Forty-seven of the Farmers Union Canal will be maintained to prevent contaminates <br /> from entering it. <br /> 3. Floodplain <br /> No 100-YR FEMA3 floodplain encompasses the mining area. <br /> 3 Federal Emergency Management Agency <br /> Mystic Soil <br /> November 2020 G-2 c. �Awerk.and lssadalCs Yt.i.i <br />
