EXHIBIT G -WATER INFORMATION <br /> This information provided in this Exhibit is intended to satisfy the requirements outlined in Section <br /> 6.4.7 of the Colorado Mined Land Reclamation Board Construction Material Rules and <br /> Regulations: <br /> (a) Locate on the map (Exhibit C) tributary water courses, wells, springs, stock water <br /> ponds, reservoirs and ditches <br /> Water well permit no. 244775. The Cache La Poudre River is approximately 1,200 feet to <br /> the south. Please refer to Exhibit C for locations of water courses in close proximity to the <br /> site, including wells, springs, stock water ponds, reservoirs and ditches. <br /> (b) Identify all known aquifers <br /> The Site is underlain by the Cache La Poudre River alluvial aquifer. <br /> (c) Show how water from dewatering operations or runoff from disturbed areas, piled <br /> material and operating surfaces will be managed to protect against pollution of either <br /> surface or groundwater both during and after the operation. <br /> Please refer to the Mining Plan Map in Exhibit C of this application. Mine areas will drain <br /> internally. Uncontrolled releases of surface water in disturbed areas will not occur. <br /> Stormwater collected in the active mine area will be managed through the dewatering <br /> system. <br /> (d) Estimate project water requirements including flow rates and annual volumes for the <br /> development, mining and reclamation phases of the project. <br /> Protected Use And Consumption: Annual evaporative depletions will be the evaporation <br /> from up to 4000 feet of 4-foot wide de-watering trench. The total area of exposed water is <br /> 0.5 acres. The gross annual evaporation at the gravel mine is 38.5 inches according to <br /> NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States. <br /> Monthly evaporative losses are determined using percentages specified by the State <br /> Engineer's Office for locations below 6,300 feet. The nearest weather station is in Windsor <br /> where the average annual precipitation is 13.97. Effective precipitation, that part of historical <br /> precipitation which was consumed by native vegetation on land to be covered by water <br /> surface, is conservatively estimated to be 70 percent of the total precipitation. The annual <br /> average effective precipitation at the property is estimated to be 9.78 inches. When <br /> subtracting the effective precipitation from the gross evaporation yields, the net annual <br /> evaporation is 28.72 inches, or 2.39 acre-feet per acre. The annual amount of evaporation <br /> from open water surfaces is 1.20 acre-feet. <br /> Mining Production &Operations: Bestway Concrete &Aggregates expects to extract a <br /> maximum of 500,000 tons annually of aggregate material from the site. The water retained <br /> in the 500,000 tons will be replaced pursuant to the Substitute Water Supply Plan (SWSP). <br /> The total annual amount of water retained in the gravel product from mining activities totals <br /> 14.71 acre-feet. <br /> Bestway Concrete&Aggregates—Lee Amendment-N La Poudre Mine—MLRB 112 Permit Application <br /> Exhibit G- 1 <br />
