R. for Proposed Rock Tunnel Pad Expansion Permit C-017-81 Dear Candace, The following information is for a technical revision to expand the rock tunnel pad area. The idea is to permit it • now and be able to fill this area with rock as it comes out - of the tunnel. As you can see by the layout of the buildings they will eventually cover this area. The buildings are pro posed to be constructed during the next 2 to 5 years (bath- house then office). The fill will be constructed the same as the main tunnel refuse pile, using standard engineering prac- tices and under the supervision of Tom Johansen, P.E. The lifts will range from approximately 1 foot on the outslopes to 2 feet maximum in the interior. The grading and compaction will be done by D-8 Caterpillar tractor. All vegetation will be removed and all topsoil will be excavated and stored on the existing (west) tunnel topsoil pile. Estimate 8" to 12" depth and approximately 700 cu. yds. (toe of existing slope to toe of new slope). As soon as the fill is completed the outslope will be covered with 12"+ of surplus topsoil from the No. 3 mine road slump area in spring of 1987. The area will then be revegetated using the 8,000' seed mix and the tunnel reclamation plan procedures. The small drainage paralleling the toe of the existing slope will be diverted south as it exits from the 36" CMP that goes under the road to the tunnel wells (see map). This drainage has a very flat slope--2 to 3 percent-- and when diverted this slope will be maintained, thus not requiring any 142
