SMUGGLER MIME SITE r~ Sa EXHIBIT B significant gullies entering or leaving the permit area. As described in Section B-3.0, ante, the soils are permeable and because of the southern exposure of the site the amount of mn-on from the slopes above is slight. The only significant surface water entering the site is direct precipitation. The site has withstood the test of time (I 10 years) without interceptor or diversion channels and very little erosion has occurred. The site has been maintained and easily handles runoff due to direct precipitation. There are two or three nominal, old erosion gullies down the face of the No. 2 Dump to the main mine bench where thunderstorm events and/or spring thaw have created sufficient runoff through the years to concentrate waters. The top of the No. 2 Dump will be regraded to drain back into the mountain to eliminate water draining over its face. Water tends to puddle on the main mine bench which has been compacted by vehicular traffic through the years. This situation is more nuisance to visitors than an environmental problem. It will be resolved by grading the area to drain into the large depression in the main mine bench. The elevation of ground water in the Smuggler Mine is approximately 105 feet below the collar of the Smuggler shaft. The elevations of the Clark and No. 2 Tunnels are 65 to 70 feet above the collar of the Smuggler shaft. Therefore, these mine entrances are approximately 170 to 175 feet above the phreatic surface. The Smuggler mine is dry above the flooded levels. At present, there is no plan to reopen the levels ofthe mine that are flooded. Mine development will be restricted to the levels above the water table. There is no record of the water in the lower levels of the mine being analyzed. The quality of the off-site ground and surface waters is quite good as reported in the FRED C. HART & ASSOCIATES, INC., REMEDIAL INVESTIGATFON/FEASIBILITY STUDY (1986). This IS COIISiStent Wlth the findings and classification of the Water Quality Control Commission, Colorado Dept of Health, acting under the state and federal Clean Water Acts, of "High Quality Waters -Class 2" for the upper reaches of the Roaring Fork River. See CLASSIFICATIUNS & NUMERIC STANDARDS FOR UPPER COLORADO RIPER BASIN & NORTFI PLATTE RIVER (PLANNING REGION 12) (WATER QUALITY CONTROL COMM'N, COLO. DEPT. OF HEALTH, 1993). B-6.0 Wildlife Wildlife use of this site is typical of sites immediately adjacent to populated areas on the outskirts of other Colorado mountain towns. Deer, fox, coyote, woodchuck, various bird species, elk, and raccoon are common. The occasional mountain lion and bear surely pass through the site. No threatened or endangered species are known to inhabit the area. Deer and elk use of the site is common which demonstrates that these species are not bothered by the existing level of activity at the site. 13 - SMUGGLER MINE SITE
