~~ Exhibit Page 26 • gravity for dewatering purposes is returned to the Dolores River, no net impact on river flow is anticipated. 7. Project water requirements: Water use for extracting and processing aggregates from Line Camp will be low. The Home Ditch provides water for irrigation of pasture and hay grass form 54.7 acres total, including 39.9 acres in the field in which the 19.1 acre permit area is located. The 39.9 acres has a historic consumptive use of 63.4 acre-feet per year, or 1.59 acre-feeUacre. Since, during actual mining operations, a minimum of six acres will be disturbed and not require irrigation, at least 9.62 acre-feet of water will be available each year, assuming all other areas are irrigated (including reclaimed areas and stockpiles). The general location and configuration of the site increase the likelihood of good soil moisture conditions to reduce dust and the need to use water for dust control. Use of dust control chemicals will also reduce water use on site. If materials are washed, water will be recycled, reducing use and discharge, as well as protect water quality. For evaluation purposes, based on the assumptions listed below, the estimated operating losses of water for the Line Camp Pit are shown in this tables Table G-3.

(Production of 200,000 tons per year would reduce this by about 50 percent, to about 9acre-feet.) • maximum affected areas are completely open and require application of water for the entire period of their use. • no precipitation during any operations on site. • no dust control chemicals be used. • no water from off-site be used for dust control. As ground water is exposed (by mining below the water table) and water is retained in surface impoundments, normally a substitute water supply plan is required to be prepared and e Based on assumptions as discussed in Exhibit M. ~ When water table is more than 1 foot below surface, without pumping or gravity flow discharge.
