1 <br />' Permanent, Man-made Structures Outside Permit Area <br />' All permanent man-made structures within 200 feet of the permit area are <br />shown on Exhibit E, Mining/Reclamation Map. The site is fairly remote. The <br />only significant, valuable or permanent man-made structure within 200 feet of <br />the affected land is Tiger Road (County Road 6). <br />' Hydrology <br /> As illustrated on Exhibit A (Legal Description and Location Map) and <br /> Exhibit E (the Mining/Reclamation Map) the permit area occupies dredge <br /> mining spoils (tailing). As such, the area is on the valley floor and the Swan <br /> River (quite a small creek at this elevation) runs adjacent to the site. The Swan <br />' River was disturbed by historic mining from above this site all the way to the <br /> Blue River (about 5 miles). There are no other ditches, reservoirs, or ponds that <br />' would receive drainage directly from the affected area. <br /> The operation will adhere to all applicable State and Federal water <br /> quality and water quantity laws and regulations. RILC is cognizant of the <br />' potential phosphorus problem in Dillon Reservoir. No chemicals will be used at <br /> this site. <br /> i <br />l <br />f <br />t <br />h <br />t <br />t <br /> ma <br />y <br />wo <br />ee <br />an approx <br />e <br />Mining of the placer tailing will not get closer t <br /> (vertical) to the water table. <br />1 <br /> Wildlife <br />t <br /> The Rock Island Operation is on the main Fork of the Swan River. <br /> Colorado Cutthroat Trout have been found in the North Fork of the Swan River. <br />' The confluence of the North Fork with the Main Fork is about one-quarter mile <br /> upstream of this site. The dredge tailing in the Main Fork has prohibited the <br />' upstream migration of Brook Trout to the North Fork through the years and has <br />effectively isolated the species. As indicated below, this operation will not affect <br /> this situation. <br /> Alex Chappell (Colorado Division of Wildlife) inspected and commented <br /> on the Alpine Rock Swan River Resource application in 1993 which included <br />t this specific site. His comments with regard to that application were: <br /> "Due to previous mining there is little wildlife utilizing this area. The <br /> dominant species are beaver, fox and coyotes. Previous disturbance <br />' precludes the area for deer and elk habitat. This project site is below the <br /> cutthroat trout reclamation area and will not have an impact on <br />' restoration efforts. Mining will not expose groundwater or disturb the <br />' 4 <br />
