Reclamation of this area will consist of reseeding the <br />dump area with grasses, shrubs and trees. Vegetation has re-established ~~ <br />on the dump area during the idle years. It is not planned. to level <br />r <br />the settling ponds as they will continue to settle suspended solids ~ ~T,<<.•' <br />from the discharge water after activity underground ceases; thereby, N °° i~ „ C <br />removing these materials prior to discharge into Four Mile Creek. ,,.." ~~,• ~,d <br />~, <br />In time, the ponds will fill to capacity but the flow will continue <br /> to be directed to Four Mile Creek. The larger culvert (36") to <br /> control the flow. of drainage from the hillside will be removed when <br /> no longer needed for rail haulage from the tunnel. <br /> 5. Mill Area - The area of greatest disturbance will <br /> be the tailings stack in the 12.7 acres south of the Mill building. <br /> The tailings will be stacked in this area at the. average rate of <br /> 2.5' per year. To prevent wind erosion, the exposed surfaces will <br /> be controlled by chemical stabilizers and immediate placement of <br />C topsoil and seeding the south slope. <br />• <br /> Drainages from the basin north of the Mill will be con- <br />\ r¢`~'F~ <br />rS <br /> ~ <br />trolled by diversion ditches around the stacking area. These are f'~ ~ ~, <br />a• <br /> ~k <br />calculated to accommodate the. 100 year flood and will be designed <br /> fora PQ of 163 CFS. The crossection wiTi be i2' wide at the bottom, <br /> 3' deep anc~.have a 1.5 to 1 side slope. <br /> Reclamation will be a continuing process during the <br />• operating period and the fina] seeding and berming to prevent wind <br /> erosion will be necessary on the top of the pile when operations <br /> cease. <br /> Maintenance of the area will be planned fora period ~ co ~ <br /> of 10-15 years as recommended by the SCS. <br /> {{ ~l <br />V <br />C <br />-~-•~ u04382 <br />
