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 /> The site is 1.45 miles north of the South Platte River, and .45 miles north of the Riverside <br /> Intake Canal. There is one lined storage pond within the permit boundary in the east of the <br /> site. Please refer to Exhibit C for locations of water courses in close proximity to the site, <br /> including wells, springs, stock water ponds, reservoirs and ditches. <br /> (b) Identify all known aquifers <br /> Groundwater was not encountered at the site borings except in isolated areas. <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-2 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 /> Dewatering will be accomplished by digging a sump, generally along the base of the mine <br /> slope, which will hold a floating pump. The pump will have an HDPE discharge line that will <br /> be routed to one of the comingled discharge points located at the site. The pump will be <br /> powered by a diesel generator housed in the active mine area. The Operator will apply for <br /> and receive a comingled stormwater and process water discharge permit prior to dewatering <br /> at the site. <br /> (d) Estimate project water requirements including flow rates and annual volumes for the <br /> development, mining and reclamation phases of the project. <br /> Water needs estimated below provide for sustained production as detailed in the Mining <br /> Plan. The Operator will adjust water supplies to account for actual demand, avoid waste, <br /> and continuously comply with laws and regulations of the Division of Water Resources and <br /> any other water agency having jurisdiction over the operation. <br /> Mining Production & Operations: <br /> An estimated 4.0 acre-feet of water per year will be used for dust control based <br /> (approximately) on 5,900 gallons per day for 5 days a week for 10 months. <br /> (e) Indicate the projected amounts of the water sources to supply project water <br /> requirements <br /> 70 Ranch—Section 25 Sand Mine—MLRB 112 Permit Application <br /> Exhibit G- 1 <br />
