EXHIBIT G WATER INFORMATION <br /> 1 . General <br /> The Delta Paving Gravel Pit is within 200 feet of the Gunnison River. The Relief Ditch and <br /> Broad Ax Ditch traverse the site, and an area of potential wetlands exists in the north near the <br /> river. The northern portion of the site is within the 100-year floodplain and partially within the <br /> floodway. Mining will not be taking place within the floodway, and appropriate setbacks are <br /> maintained from all waterways, as can be seen Map C-2. Groundwater is located roughly four to <br /> five feet below the natural grade as part of the shallow aquifer of the Gunnison River. Multiple <br /> groundwater wells are located on site, supplying the water for consumptive use at the Delta <br /> Paving operation. Grand Junction Pipe & Supply Co. is committed to protecting the hydrological <br /> balance and water quality at the site. <br /> 2. Water Quality Protection <br /> The primary concerns surrounding water quality protection at the Delta Paving site are the <br /> potential impacts to the surface and groundwater from sediment, hydraulic fluids, and diesel <br /> fuel. Sediment will be controlled through the use of stormwater retention within the disturbance <br /> area through the life of the mine. The site will be graded in a manner that maintains all surficial <br /> flows within the disturbed area, in turn containing all sediment and unwanted discharges from <br /> leaving the site. Hydraulic fluids and diesel fuels will be contained within vehicles or with <br /> adequate storage methods that follow best practices of maintenance; these practices including <br /> regular inspections of vehicles, hydraulic lines, and any other potential spill sources. Diesel fuel <br /> will be stored on-site in double walled tanks with secondary containment. Fuel storage will be <br /> stored away from exposed groundwater and other waterways. Spill kits will be located near all <br /> fueling areas to clean up inadvertent spills as soon as possible. An SPCC plan will be in place <br /> to prevent oil discharges and establish a response procedure in the event of spills. <br /> Any surface water discharges from the site will be sampled in accordance with the NPDES <br /> discharge permit. The discharge permit, COG500444, requires sampling at Outfall 001A <br /> (mapped in C-1 and C-2) as defined in Table G. <br /> Delta Paving Gravel Pit G-1 Lewicki&Associates <br /> September 2022 <br />
