Logan Wash Mine TR No. 4 <br />The Guardian® tackifier will be applied with the hydro-mulch materials. No fertilizer will be <br />applied during seeding. Fertilizer may be applied in subsequent years if needed. <br />Biosol® was selected as an amendment for the slope terraces to accelerate the growth process in <br />the harsh south-facing, steep-sloped environment. Biosol® is an organic fertilizer obtained from <br />a fungal biomass (mycelium) that is produced from the production of penicillin. The fertilizer <br />exhibits slow-release properties of nitrogen and is believed to stimulate natural soil microbial <br />biomass, humus, and root mass. <br />Terrace construction and transplanting is scheduled for the Lower Dump during the fall of 2003. <br />Current Status <br />The installation ofhand-excavated terraces and seeding of the terrace was completed on the <br />Lower Dump during the summer of 2003. Seedling planting is approximately 50 % complete. <br />2.2 Upper Waste-Rock Slope (Area la) <br />The Upper Waste-Rock Slope (Upper Dump) refers to the portion of Area 1 a immediately north <br />of Area 3 and west of Area 2 on Exhibit F. The Upper Dump is estimated to consist of 6.5 acres <br />of steeply sloping (in excess of 35 degrees) waste rock material. The slope extends from the <br />northern portion of the Upper Bench at an elevation of approximately 7,825 ft to the Lower <br />Bench at an elevation of approximately 7,575 ft. <br />Proposed Reclamation <br />The initial Plan calls for revegetation of Area la by hydro-seeding methods with no top soil <br />added. As discussed above for the Lower Waste-Rock Slope, OOSI does not believe direct <br />hydro-seeding of the steep, south-facing slope will be an effective reclamation method. OOSI <br />therefore intended to propose to reclaim the Upper Waste-Rock Slope in a similar manner as the <br />Lower Dump slope, as described above. However, initial efforts by OOSI to construct hand- <br />excavated terraces on the Upper Dump proved unsuccessful. It was found that the areas on the <br />Upper Dump that contained sufficient fine material to support plant growth is also very non- <br />cohesive and terraces would not maintain integrity. <br />Therefore, OOSI proposes to install small hand-excavated "pockets" or holes in select areas on <br />the Upper Dump. The pockets will be approximately 2-ft wide by 1-ft deep. Pockets will be <br />installed where the waste rock material has a sufficient component of fine soil-like material to <br />support vegetation growth. The pockets will be constructed in groups so as to form vegetated <br />island areas. Terrace seeding of species shown in Table 1 and transplanting of plants shown in <br />Table 2 will be implemented on the Upper Dump similar to procedures discussed for the Lower <br />Dump. Seeding will be conducted by hydro-mulching methods, with efforts concentrated on the <br />pocketed areas. Transplanted plants will be installed in additional pockets in and around the <br />hydro-mulched vegetated islands. <br />Western Water & Land, Inc. 3 <br />
