Dept. of Natural Resource <br /> The following points will be incorporated in the Red <br /> Jasper Granite operation as per our conversation of <br /> October 25 , 1982 . <br /> (1 ) The proposed 50 ' High hall to be left on the Southern <br /> side of the quarry (Southern portion of the Red Area <br /> Map 2) will be segmented at the 2S ' level with a bench . <br /> Bench width will equal blade width , but will not be <br /> less than 10 feet . The bench should slope 1 -2% for <br /> drainage and be inclined 1 - 2 feet toward cut slopes . <br /> The top portion of the high wall will be pulled back <br /> to a 1 . 2S to 1 slope . (Figure 1) <br /> (2) The pad (working surface) will be constructed so <br /> that it dips 1 - 2% to the northwest in order to drain <br /> into the tallus area below the pad . <br /> (3) It is anticipated that the shortage of topsoil will <br /> limit the full coverage of the mined area at the <br /> prescribed depth of 8 -10" of topsoil . Therefore , it <br /> is proposed that the topsoil will be replaced on the <br /> mined area at a depth of 8 -10" in areas where pockets <br /> of topsoil will be stable and have less chance of <br /> eroding (i . e . , near the High hall and away from the <br /> Callus drainage areas) . This selective placement of <br /> topsoil will insure the best chance for vegetation <br /> establishment . <br /> Sincerely , <br /> William R. Beavers <br />
