Exhibit G — Water Information <br />Paul Banks and Associates, LLC <br />Overview <br />The Debeque Sand and Gravel Resource is an alluvial deposit located adjacent to the <br />floodplain of the Colorado River. Test pits at the proposed reclamation permit site show <br />an average groundwater depth approximately 5 feet below the land surface across the <br />site. <br />Based on standard practices, no adverse quantitative or qualitative effects to surface <br />waters are expected to result from the proposed Debeque Sand and Gravel Resource. <br />Notably, an existing "gravel pit lake" occupies land immediately west of the proposed <br />operation, but that lake is held in common ownership and will be able to absorb any <br />fluctuations in water level. Groundwater effects on wells in the area will be minimal. <br />Water Requirements <br />Water demand at the proposed construction materials operation will be generated by (a) <br />worker demands for potable water, (b) dust control, (c) process water (e.g., aggregate <br />washing), and (d) augmentation or temporary substitute supplies for depleted waters due <br />to evaporation. <br />Water demands at the site are calculated based on an assumed maximum working <br />season of 240 days. Potable and sanitary uses for an estimated 10 on -site employees <br />will require approximately 0.1 acre -feet per year (33,000 gallons). Dust control creates a <br />demand of approximately 2.4 acre -feet (783,000 gallons), or approximately 5,000 <br />gallons on each working day at the mining site. Process water will be obtained from <br />dewatering water and recycled water. The Applicant has confirmed the availability of <br />augmentation water from several local sources, well in excess of any potential <br />augmentation or substitute supply requirement. <br />The operation may also include a concrete and /or asphalt plant facility, but this water <br />demand is not specifically linked to the Reclamation Permit. <br />Potable and sanitary water needs will be supplied by bottled water and portable toilets. <br />Debeque Sand and Gravel Resource 11019 <br />Oldcastle Southwest Group, Inc. 16 November 2011 <br />
