Hydraulic conductivity for the undisturbed rock types present at the site, in-situ before mining, ranges from 10-2 - <br />10+2 gallons per day per square foot (as reported by Freeze and Cherry (1979)) due to joints and fractures in the <br />rock. The existence of the underground mine workings provide a direct hydraulic conduit for groundwater beneath <br />the site. <br />The Argo Tunnel, the major drainage for the area, lies approx. 1,500 feet directly below the site. The Argo Tunnel <br />drainage is monitored, collected, and treated at the Argo Tunnel Treatment Facility located in Idaho Springs. This <br />tunnel was constructed in the early 1900's to access and drain the mines in this vicinity. The portal is located near <br />the center of Idaho Springs. <br />Baseline groundwater quality is carefully observed at the Argo Tun iel by the US EPA and the CDPHE. Sample <br />data is included in Exhibit C. <br />The proposed affected area currently does not produce any surface discharge and no discharge will result from the <br />proposed operation. It must be remembered that the dump is being removed and the site is being reclaimed. <br />6.3.2(d) <br />Wildlife Statement: <br />Letter from CO Div. of Wildlife attached in the appendix of this Exhibit B <br />Appendix to Exhibit B <br />1.
