Water quality in side canyons of the river should not be <br /> effected by mining operations because of limited surface disturbance <br /> contributing to water quality deterioration. <br /> Assessments of springs and seeps (Appendix 4 ) and area water <br /> users (Appendix 5) indicate that mining at the New Elk and Golden Eagle <br /> Mines should not effect current uses of surface and ground waters. <br /> 4. 0 MITIGATIVE MEASURES <br /> Various designs of mine operations and facilities have been <br /> incorporated to minimize disturbance of area hydrologic functions at <br /> the New Elk and Golden Eagle Mines. <br /> The primary mitigative measure is the surface water control <br /> plan which is discussed in the mine permit application. This plan <br /> provides for the implementation of ditches and impoundment structures <br /> which control the quantity and quality of runoff generated from the <br /> mine affected area. These affected areas include mine discharges, <br /> refuse disposal areas , coal stockpiles and sediment control from <br /> disturbed areas. <br /> A spill prevention control plan has been prepared and can be <br /> implemented as situations arise . Generally , the plan calls for <br /> containing any potential spills ( i .e . , oil, diesel fuel, gasoline, <br /> etc. ) and preventing the material from contaminating surface and/or <br /> ground water. <br /> Reclamation plans have been developed to restore surface <br /> lands and drainage. These plans are discussed in detail in the mine <br /> permit application. <br /> A survey of all water users of both surface and ground water <br /> has been made and an assessment of potential impacts completed. This <br /> information is contained in the mine permit application and Appendix 5 <br /> of this report. No major changes have been observed since the survey <br /> 18 <br />
