r? <br />U <br />• Because water will be imported from an area about 15 miles downstream and will <br />be consumptively used within the Study Area Boundary, with the exception of <br />minor water used for domestic purposes, there will be no water added to local <br />drainages or extracted from the local hydrologic system for operation of the mine. <br />• Mine inflow water, normally tributary to streams that drain this portion of the <br />Book Cliffs, will be discharged to a dry unnamed tributary below the proposed <br />portal at an average maximum rate of 50 gpm. The expected water quality of the <br />mine water is comparable, if not better, to surface water that currently drains from <br />the area (East Salt Creek). <br />• Mine discharge water will probably flow less than 1,000 feet from the portal and <br />not leave the permit area as surface water. This analysis does not consider losses <br />due to evaporation/transpiration, which could be considerable during certain <br />seasons, and decrease the surface water flow distance. <br />• Because there will be no discharges to drainages within the Study Area Boundary, <br />there will not be any impact to possible AVFs located more than 6 miles <br />downstream of the Study Area Boundary. There will be no water discharges or <br />withdrawals from tributaries to Big Salt Creek. <br />• Based on these facts, AVFs located in the East Salt Creek and Big Salt Creek drainages <br />should not be considered adjacent areas, as defined by the regulations. Therefore, there <br />are no AVFs within and adjacent to the proposed Study Area Boundary for the Red Cliff <br />Mine. <br />• <br />ERO Resources Corp.
