Box 177 <br /> Silverton, CO 81433 <br /> contact William B. Goodhard <br /> Resident Manager <br /> Identification of Lands <br /> Surface tailings pond and mine waste dumps located at head of Placer Gulch, San Juan <br /> County, Colorado. Work also to be done for closure of#1 level of Gold Prince Mine. Lands are <br /> included in SGC's Stormwater Permit #COR-040061. See attached map. <br /> Identification of the Waters of the United States Potentially Affected <br /> Water flows from above the property into Placer Gulch and joins the Animas River at Animas <br /> Forks. See attached map. <br /> Physical Description of Conditions <br /> The site is a historic mine and mill which operated around the turn of the century. Prior to <br /> the ore being shipped to Animas Forks via aerial tram, it appears that some milling was done on site. <br /> The historic milling activity left a small tailings pond which is partially uncovered and allows for <br /> snowmelt and rain waters to cross, and potentially pass through, the tailings. Waste dumps occurring <br /> on the property and bordering the stream also are not covered. The number one portal has a closure <br /> bulkhead in place to prevent entry; however, it needs to be reinforced to create a water retaining <br /> bulkhead. The flow through the mine workings would then be reduced as the tunnel will no longer <br /> be a natural drain for the overlying area. It is possible that the water could backup and flow into the <br /> Sunnyside Mine via old drifts and raises. This water is of similar or better quality than that projected <br /> to flow into the mine pool from other sources and the quantity is relatively insignificant in <br /> comparison. Therefore no adverse impact would be anticipated if this were to occur. <br /> 1 <br />
