I The temporary upland diversion above the aspen test plot area was being re-worked at <br />the time of the inspection to correspond with the design specified in TR-45, depicted <br />on Exhibit 13-2. The steep light use road that originally provided access to the site has <br />been eliminated and topsoiled and will need to be seeded. <br />Aspen Test Plot schedule of work this year includes selection of aspen saplings to be <br />transplanted, installation of the irrigation system, grading of the plot area to eliminate <br />rills and establish uniform 4 foot soil thickness, planting of selected aspen saplings <br />along with Planting List 3 shrubs, seeding with Seedmix 6, and completion of fence <br />construction. A minor revision(s) to the appropriate SCC permit(s) will be submitted by <br />August 1, 2004, to designate the aspen sapling harvest locations, and describe <br />measures that will be taken to minimize and repair associated d'fsturbance. <br />Although not a component of the current aspen study, the operator has committed to <br />the establishment of an aspen "farm plot" by clear-cutting a suitable area of mature <br />aspen forest. Two to three acres would be cut during the 2004/2005 dormant period. <br />The purpose is to stimulate suckering to provide a source of sufficient numbers of <br />aspen saplings for use in future mine site plantings. Specific location(s) and <br />specifications for the treatment area(s) need to be selected and defined this summer <br />and should be included in the above referenced minor revision or other appropriate <br />revision to be submitted by August 1, 2004. <br />Slides and Damage <br />The slide area on the east side of the ridgeline that occurred in 2001 during active <br />operations of the ridgeline pit appears stable, with no apparent cracking or slumping. <br />Seeded grasses are establishing well, and there is minimal erosion. <br />A number of areas of settling and slumping were observed on recently graded highwall <br />slopes in the "A" Pit area, older graded and revegetated areas of the "D" Pit, and slopes <br />adjacent to Sediment Ponds 016 and 016A. These areas are described in previous <br />sections of this report, and will be inspected by DMG's staff engineer as a part of the <br />May inspection. <br />13 <br />
