March 2, 1994 -5- 933-2714 <br />' ~ Groundwater in the Bulldog Mine area probably flows southeast along the fault that trends <br />down Windy Gulch and dischazges to Willow Creek at the confluence with Windy Gulch. <br />Water quality samples taken in Willow Creek above and below Windy Gulch do not indicate <br />any measurable impacts from mine dischazge. <br />' The elevation of the lowest Bulldog Mine portal at elevation 9360 is above the water table, <br />which was encountered in the mine at elevations below 9200 feet. Thus, resaturation of the <br />lower portions of the mine workings will not result in discharge out of the portal. <br />Homestake will conduct a spring and seep survey this summer to confirm that the mine has <br />not caused any new seeps or impacted any existing seeps. The spring and seep survey will <br />be conducted in Windy Gulch at elevations below about 9200 feet, which is the highest level <br />' that the water table could be at based on observations during mining. <br />We trust that this information adequately documents the hydrogeologic conditions associated <br />with the Bulldog Ivfine. Contingent upon the results of the spring and seep survey indicating <br />no significant impacu from the mine, it is our understanding from the February 10, 1994 <br />' meeting that the Colorado Department of Health will release the existing dischazge permit. <br />Should you have any questions regarding this information please contact me or Jerry Rowe <br />with Golder Associates at (303) 980-0540. <br />Sincerely, <br /> <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br />COMPANY <br />Corporate Manager, Environmental Affairs <br />LR/sa <br />Attachments: 1. <br />2. <br />4. <br />5. <br />6. <br />Quad Map <br />Photographs <br />Geologic Map <br />Mine Map <br />Water Quality Data Plots <br />Laboratory Results <br /> <br />
