The Coherex storage tank and loading area at the Ten Mile Barge site is visually inspected to <br /> assure the integrity of the tank and its containment berm. <br /> 6.0 Groundwater <br /> Groundwater issues at hard rock mine sites are regulated by the DMG. Climax personnel have <br /> worked closely with the DMG to develop an adequate monitoring program. Specifics of this <br /> program including background analytical results are presented in Appendix K. Additional <br /> information regarding aquifers, faulting in the Climax area, and hydrogeology is located in Section <br /> 8 of the Mining and Reclamation Permit. Information also is located in the 1989 Amendment to <br /> the Mining and Reclamation Permit. <br /> 6.1 Background and Program <br /> The groundwater program at the Climax Mine entailed drilling four (4) monitoring wells and <br /> conducting sampling and analysis of those wells (Appendix K). The first two wells were <br /> completed in 1984 in the Ten Mile Creek valley below the Mayflower tailing impoundment. The <br /> • third well, located in the Eagle River watershed between the Robinson Dam and Eagle Park <br /> Reservoir, was installed in late 1993. Likewise, the fourth well was drilled and completed in late <br /> 1993 in the Arkansas River watershed at the southwest corner of the gravel pit. Groundwater <br /> has been monitored in the Eagle River and Arkansas River watersheds since late 1993. <br /> Monitoring of these wells occurs quarterly. During the third quarter of 1995, the DMG will <br /> determine the level of groundwater monitoring required at Climax. This determination will be <br /> based upon an analysis of the monitoring data submitted by Climax. <br /> 6.2 Groundwater Quality <br /> Groundwater wells presently are sampled on a quarterly basis (this rate is subject to regulatory <br /> change). Analytical data from the fourth quarter, 1993 through the fourth quarter, 1994 are <br /> presented in Appendix K. The long term data including the data in Appendix K strongly support <br /> the position that no impact to groundwater has occurred in the Ten Mile drainage. Given the <br /> history of the Climax Mine, groundwater does not appear to have been impacted in any of the <br /> affected drainages. <br /> 7.0 Surface Water <br /> • Information relative to surface water containment and control facilities, surface water the <br /> quality, <br /> 36 <br />
