Volume: use 14'X14' portal (considering over - break) <br />(14'X14'X60') = 11,760 cubic feet; 11,760 cubic feet / 27 cubic feet/ cu. yd. <br />= 436 cubic yards. <br />Re- contouring: The pre- disturbance slope (natural slope) at the portal bench averages 2.3H:1V. <br />RGS plans to re -slope the cut slope above the portal bench to about pre — disturbance <br />conditions. The out -slope of the portal bench (fill area) will also be re- sloped to about 2.3H:1V. <br />As shown on the sketches provided, there will be a relatively flat area in the middle of the <br />reclaimed bench. This area will be graded at about 2 -3% away from the cut slope. The portal <br />bench access road will be re- contoured back to pre- construction topography. <br />The development waste rock dump will be graded to 2H:1V final slopes. <br />All other reclaimed areas will be graded back to about their original configuration. Positive low - <br />gradient drainage will be maintained. <br />Reclaim areas: All new disturbance and reclaimed areas that are disturbed will be reclaimed. <br />Approximately 6 inches of soil medium will be scraped off all disturbed or re- disturbed areas <br />and pushed into windrows around the property perimeter. Soil medium removed from the <br />portal bench area will be pushed into a windrow at the base of the bench toe. There may not <br />be 6 inches of growth medium available from the slopes that will be disturbed around the <br />portal bench. The soil medium will be seeded with the approved interim seed mix, stabilized <br />and left in -place until reclamation. The soil medium will be replaced (4 inches) over the <br />disturbed area. Due to the new landforms created by the portal bench and waste rock dump <br />and the possible lack of soil medium to be salvaged, there may be a shortage of soil medium. <br />Any additional soil medium needed for reclamation will be borrowed from the tailings area and <br />brought to the site. It is estimated that 5.6 acres where soil medium will be replaced. See <br />Figure 3. <br />Certain facilities will remain as permanent structures. The areas occupied by these structures <br />will not be reclaimed. <br />The following structures and facilities will remain as permanent: <br />➢ Administration Building <br />➢ Potable Water Tank <br />➢ Electrical Sub - Station <br />➢ Main Access Road & Parking Area <br />➢ Water & Sewer Hookups and Pipelines & Pump House <br />1 R- 1c8'_Response to PAR Letter 1 &S.c1oc 9/26 /2011 <br />9 <br />
