environmental impacts. Mining activities did not impact the recharge areas of the T~ventymile Sandstone aquifer <br />nor result in disturbance of the actual stream channel of any major area drainage, By minimizing the total amount <br />~f area which was disturbed, the resultant potential groundwater impacts were minimized. The overall effect on <br />the area groundwater hydrologic system will be dependent on the long-term hydrologic characteristics of the <br />reclaimed backfill areas. <br />The areas of disturbance are bounded by surface drainage features, which channel and convey limited runoff from <br />snowmelt in upland areas through the Eckman Park Mine area. Minimal stream channel disturbance resulted from <br />mining-related activities; no major drainage diversion channels were constructed <br />As noted iit the response under Section 780.11, the operation plan reflected direct sidecasting of excavated spoil <br />tnaterial into adjacent draws or previous cuts. This operating method minimized the area of disturbance, limited <br />the surface area of spoils exposed to <br />• <br />n <br />U <br />1996 Permit Ren.
