EXHIBIT G WATER INFORMATION <br /> 1 . General <br /> The Marcovich Mining Resource is within the floodplain and floodway of the South Platte River. <br /> There is a return irrigation ditch that traverses from east to west through the center of the site. <br /> Stock ponds have been constructed south of this ditch and are filled by return irrigation water <br /> from the parcel sound of the permitted area. Mining within the floodway will be conducted with <br /> no filling or stockpiling above the natural ground grade. Groundwater is located roughly five feet <br /> below the natural grade. All groundwater onsite is part of the South Platte River alluvial aquifer. <br /> Prior to mining, a slurry wall will be installed around the perimeter, as shown on Map C-3. These <br /> slurry walls will be for the development of water storage reservoirs following reclamation. <br /> Asphalt Specialties is committed to protecting the hydrological balance and water quality at the <br /> site. <br /> 2. Water Quality Protection <br /> The primary concerns surrounding water quality protection at the Marcovich Mining Resource <br /> site are the potential impacts to the surface and groundwater from sediment, hydraulic fluids, <br /> and diesel fuel. Sediment will be controlled through the use of stormwater retention within the <br /> disturbance area through the life of the mine. The site will be graded in a manner that maintains <br /> all surficial flows within the disturbed area, in turn containing all sediment and unwanted <br /> discharges from leaving the site. Hydraulic fluids and diesel fuels will be contained within <br /> vehicles that follow best practices of maintenance; these practices include regular inspections of <br /> vehicles, hydraulic lines, and any other potential spill sources. Diesel fuel or other oils will not be <br /> stored on-site. <br /> Any surface water discharges from the site will be sampled in accordance with the NPDES <br /> discharge permit. All discharge will be via the approved Outfall, the proposed location of which <br /> is shown on Map C-3. <br /> Marcovich Gravel Pit <br /> May 2024 G-1 El Lewicki 8(Associates <br />
