The pad fill that is placed above the ADS will be inert waste rock. A raised berm will be <br /> created at the upstream end of the fill and ADS inlet to intercept gulch flows. The margin <br /> of the both(upper and lower)pads' surfaces will be bermed for stormwater containment <br /> (the berm will be at least 3 feet high as a safety requirement). The lower pad surface will <br /> be graded at 1%slope to direct any precipitation falling on the pad and upper slope to a <br /> stormwater pond at the downgradient end of the lower pad(see map). Although the <br /> waste rock will be very porous and most precipitation will percolate into the dump and <br /> gulch,the stormwater pond will have a designed outlet and riprapped spillway,to control <br /> sediment. Any overflow from the stormwater pond will be conveyed by riprapped ditch <br /> to the invert of the gulch at the ADS pipe outlet below the toe of the dump. Straw wattles <br /> or similar sediment control structure will be staked below the toe of all placed dump <br /> material, and around all stockpiled soil. <br /> The outslope of the waste rock dump will be graded to no steeper than 2:1 (H:V). During <br /> mining, the pad slope will be maintained at 2:1. Someday if the 300 or 400 Level <br /> workings intercept the Gold Links Mine workings,which will allow sending ore out of <br /> the Gold Links portal instead of trucking it down Halls Gulch,the waste dumps will not <br /> expand any more. After the dump and pad have reached the full size,and the dump <br /> outslope configuration is permanently established, soil will be placed there from the <br /> stockpile and seeded. <br /> The features of the waste rock pad will include a portable steel building on skids to <br /> contain equipment, and store materials and fluids. The building will be approximately <br /> 8x20 ft. The pad will also contain a wheeled air compressor and materials storage area. <br /> The portal will remain as permanent. Other site features, such as portable equipment, <br /> piled materials, ventilation fan, etc.,will be removed at the conclusion of the mining <br /> stage. <br /> All fluids, such as fuel, other hydrocarbons, antifreeze,etc., will be stored the building, in <br /> their original labeled containers, and adequate impermeable secondary containment will <br /> be provided. These materials will be removed at the conclusion of mining and <br /> reclamation. <br /> In stage one mining,the 400 Level workings will advance. For the second stage of the <br /> mining plan,the 300 Level adit will be reopened and tunnel driven(see Exhibit E maps). <br /> Since it is anticipated that new tunneling to connect to existing underground workings <br /> will be limited,there will be little waste rock to be mucked out and placed on the pad. <br /> All roads to be used to access both portal levels on the site currently exist and will remain <br /> as permanent features,per the landowner's wishes. Drainage controls on the site, such as <br /> underdrains and berms will also remain to help ensure the longterm stability of the roads <br /> and the site. <br />
