EXHIBIT E <br /> 2.1 Soil Management, Erosion, and Sediment Control <br /> Sustainable soil management and erosion control are essential for maintaining land quality during construction and <br /> mining activities.Key strategies include preserving topsoil for reclamation,implementing tailored surface water drainage <br /> systems to prevent erosion,and controlling dust through track-out mats and regular water spraying.Native grasses will be <br /> planted on disturbed areas to stabilize soil,support ecological health,and manage noxious weeds.Additionally,low-noise <br /> equipment will be utilized to minimize environmental impact,promoting long-term sustainability. <br /> 1. Topsoil Preservation <br /> Effective soil management and erosion control are essential for sustainable land use.A primary strategy in this process <br /> is the preservation of topsoil.During construction and other land-disturbing activities,topsoil will be carefully <br /> removed and stockpiled separately to facilitate its reuse in reclamation efforts. Proper storage techniques,such as <br /> covering with geotextile fabric or establishing a protective cover crop,will maintain the soil's fertility and structure, <br /> preventing compaction or erosion during storage. <br /> 2. Surface Water Management <br /> Surface water management is crucial for reducing erosion potential and preserving soil integrity. Designing tailored <br /> drainage systems to manage surface water flow will prevent erosion effectively. These systems will be adapted to the <br /> site's natural water flow patterns,with attention to mitigating effects of heavy rainfall. By channeling water away from <br /> vulnerable areas and regulating flow rates,these systems minimize soil erosion and sediment displacement,thereby <br /> protecting water quality in nearby streams and rivers by reducing sediment runoff. <br /> 3. Dust and Erosion Reduction <br /> Dust and erosion control are vital components of soil management. Track-out mats will be installed at major road <br /> entrances,exits,and mining block entrances to reduce soil and dust transport off-site.Regular water spraying will <br /> control dust on exposed soil surfaces,improving air quality and visibility. In erosion-prone areas,physical barriers like <br /> silt fencing and coir logs will trap sediment and slow water flow,further mitigating erosion risks. <br /> 4. Erosion Control Plantings <br /> Erosion control plantings are an effective soil stabilization method. Quick-growing cover crops or grasses will be <br /> established on bare or disturbed soil to provide immediate erosion protection. These plants help anchor soil with their <br /> root systems,reducing the risk of soil displacement by water or wind.Additionally,these plantings contribute organic <br /> matter to the soil,enhancing soil health and promoting biodiversity. By incorporating erosion control plantings <br /> into soil management practices,the project will foster resilient landscapes that support long-term environmental <br /> sustainability and reduce erosion and sedimentation impacts. <br /> To further control dust,track-out mats will be used at roadways,mining block entrances,and the wash plant. State- <br /> of-the-art equipment with low sound emissions will also be employed in mining operations and the recovery plant to <br /> minimize environmental impact. <br /> 31 <br /> HARDROCK/METAL MINING REGULAR(112)APPLICATION Au Pt Industries LLC I PO Box 1424-Edwards,Colorado 81632 1970 306 1 784 <br />
