• PROBABLE HYDROLOGIC CONSEQIIENCES <br />The mines will have negligible effect upon the hydrologic regime of East Salt Creek. The area <br />disturbed is small, sedimentation and surface water systems have functioned well for over ten <br />years. The inherent poor quality of surface water in the area is the result of site speciSc <br />environmental factors not from any impact caused by the mines. <br />Most storm events that have exceeded the design criteria required by DMG have not been a <br />problem for the system to handle. The effect that the mine has on the groundwater hydrology of <br />East Salt Creek has been decreased further since water is now being imported to the mine and no <br />further dewatering will take place until water in 001 North Section backs up to the seals and is <br />drained to the water sump or water is intersected east of the current workings. <br />if there are questions or if I can be of further assistance please contact me. <br />Sincerely, <br />M. Walters <br />Manager of Mine Services <br />i <br />• <br />AHR -97 Page-5 2-6-98 <br />
