EXHIBIT G Water Information See existing and proposed pit drainage discussion and maps in Exhibit C4,Drainage. Butala maintains Colorado Discharge Permit System (CDPS) COG500476 water discharge permit with CDPHE for two discharge points to the Arkansas River. Both have flows recorded and are sampled tested twice monthly with all results submitted to CDPHE/Water Quality Division.All surface outflow from the property passes through those discharge points. Seep water and stormwater drainage is constantly controlled in the pits. Wet material is difficult to dry screen, slows production and yields sandy cobble rock. Therefore, ditches and culverts are in use at all time to cut off seepage and to channel surface flows. These directed flows are kept away from any chance of contamination by shop repairs, parked equipment or fueling stations. Water quality testing is very sensitive and we are always looking for ways to avoid contamination. Our water quality consultant,Pinyon Environmetal,has recommended several construction efforts to avoid runoff contact with slag near the river. These projects are awaiting COE 404 permitting and should be underway in 2024. Pinyon performs the CDPHE required testing plus random testing of ditches, springs and seep areas. Sources of contaminants is always in discussions. All drainage from the property is directed to settling ponds that include meandering courses and weirs to retard any debris or contaminants. These ponds remain clean for at least five years between cleaning because the water throughput is clean form filtering through cobbly layers. Separate settling ponds are used to clean discharge from the sand wash plant. The plant uses pumped water from the last settling pond along the river,near Discharge Point 00IA. After the wash water passes through ponds and across weirs,it is discharged to the river at at point 002A. The plant operated in warm weather only and is in use approximately 15 weeks per year. The throughput of sand is 140 tons per hour and water is pumped at 600 GPM through spray bars. Wet sand is dewatered by a twin screw auger and sand is stacked by conveyor. Our facilities operate in concurrence with a SWPPP which includes pollutant such as fuels,motors, chemicals, etc. If a spill occurs, any product involved is pulled from inventory and treated according to the conditions. Site contaminations are dug up and removed or treated. Operators are trained to check equipment for leaks daily. We can not afford to contaminate our decorative products. Our sand wash plant uses pumped water from the last settling pond along the river. EXHIBIT H Wildlife Information Wildlife species: Mule deer, Coyote, Fox,rabbit, Richardson ground squirrel,Deer mouse, Skunk, Bushytail wood rat, magpie, raven, crow, Stellar's Jay, Sparrows, Nitehawk, Hairy woodpecker, mountain bluebird. Wildlife conditions are relatively unchanged since 1977 application: "This area is mostly biologically sterile because of past smelter activity. Because of this, wildlife impacts will be negligible." (Jack Vayhinger&Willy Travnicek) Reclamation shall promote wildlife through revegtation.
