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. Elam construction is committed to protecting the hydrological balance and <br /> 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 /> 3. Floodplain <br /> The majority of the site is within the 100-year floodplain while the northern portion of the site is <br /> within the floodway as reported by the Federal Emergency Management Agency. These <br /> boundaries are shown in the Exhibit C and F maps. The minimum distance maintained from the <br /> Gunnison River to excavation activities is 100 feet. Additionally, no excavation, construction, or <br /> other development will occur in the floodway. No permanent elevation of grades will take place <br /> within the 100-year floodplain. All topsoil and overburden stockpiles will be temporary during <br /> mining and will be removed during reclamation. Overall, the downstream flood impacts should <br /> remain the same or be reduced from activity at the site as the removal of material results in <br /> more storage space for flood water below the existing grade. <br /> Delta Paving Gravel Pit G-1 ®Lewicki 81 Associates <br /> April 2022 <br />
