Logan Wash Mine TR No. 4 <br />the mine, a significant amount of vegetation has naturally established itself along the margins of <br />the access roads. Because of this, OOSI proposes to rip the road surfaces, recontour unvegetated <br />berms to blend with surrounding topography, and revegetate the disturbed surface using a range <br />drill or broadcast methods, depending on soil conditions. Straw mulch will be crimped into the <br />surface following seeding. If crimping is not practicable due to rocky soils, the straw will <br />applied as a hydro-mulch material at a rate of 2,000 lbs per acre and tackifier will also be <br />applied. The following table shows the reclamation materials proposed for use on reclamation of <br />roads. <br />Road Reclamation Materials <br /> <br />Material Application Rate <br />lbs er acre <br />Seed mix (Table 1) 17.5 <br />Straw mulch (option 1) 2,000 <br />Mat fiber hydro-mulch (o tion 2 2,000 <br />Guardian® (tackifier) 60 <br />No fertilizer a lied during seedin - <br />No shrub transplanting - <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 />Current Status <br />Approximately 25% of the Upper Bench access road was scarified and seeded during the <br />summer of 2003. This includes the section nearest to the Upper Bench itself. The Lower Bench <br />access road and the Lower and Upper main access roads have not yet been reclaimed. <br />4.0 Chain-link Rock Protection <br />During mine construction, the upper bench headwalls were secured by chain-link netting to <br />protect the bench from serious rock falls. This netting is still in place and will be removed. The <br />netting covers an upper highwall that is approximately 100 ft high and 200 ft long. Two lower <br />highwall sections are approximately 75 ft high by 500 ft long and 80 ft high by 60 ft long. The <br />upper highwall section of netting is bolted to the rock outcrop with metal banding and rock bolts. <br />The metal banding extends the full length of the highwall at two different elevations, <br />approximately 40 ft apart. A partial rock-bolted band fastens the netting on the lower highwall. <br />Proposed Reclamation <br />OOSI will remove the chain-link netting from the vertical portion of the highwal]s and dispose of <br />the waste material at an onsite location (place in the L-1 Drift). The chain-link netting will be <br />cut in sections, working from the top of the highwall to the bottom. Any loose metal-banding <br />and rock bolts will also be cut from the face. Existing exposed anchor posts will also be cut at <br />Western Water & Land, Inc. 7 <br />
