accumulation at the slope base,and reduce hydrostatic pressure that could lead to slope failure. <br /> 5.4 Monitoring and Maintenance <br /> Continuous monitoring will use both manual and technological methods,including slope stability radar,to assess the <br /> structural health of slopes consistently. Regular maintenance strategies,guided by ongoing assessments,will ensure slope <br /> stability throughout the mining process,with management practices adjusted as necessary to respond to any changes in <br /> slope conditions <br /> • Continuous Monitoring:Utilization of manual and technological methods,including slope stability radar,to continu- <br /> ously monitor the structural health of slopes;when necessary. <br /> • Maintenance Strategies: Regular maintenance based on ongoing assessments will ensure that the slope remains stable <br /> as mining progresses,adjusting management practices in response to any changes in slope condition. <br /> 5.5 Environmental Considerations <br /> 5.5.1 Erosion Control <br /> Erosion control strategies align with Rule 3.1 of the CDRMS regulations,focusing on stabilizing disturbed surfaces and <br /> minimizing environmental impact. The project employs geotextiles,native vegetation,silt fences,and fiber rolls as part of <br /> a comprehensive erosion control plan.Revegetation efforts,guided by Rule 3.1.10,include the use of a tailored native seed <br /> mix to restore soil stability and support ecological recovery. <br /> • Use of Geotextiles: Geotextiles are permeable fabrics which,when used in association with soil,have the ability to sep- <br /> arate,filter,reinforce,protect,or drain. They are employed on slopes to enhance soil stability and prevent soil erosion <br /> by stabilizing the ground and facilitating vegetation growth. <br /> • Vegetation for Slope Stabilization: Imprint seeding of native grasses and shrubs will be used to help with stabilization. <br /> • Native Grass Specific Seed Mix: To effectively stabilize slopes and prevent erosion,a tailored seed mix is used. This <br /> mix includes: <br /> Indian Ricegrass-22% <br /> Bluebunch Wheatgrass- 18% <br /> Thickspike Wheatgrass- 17% <br /> Slender Wheatgrass- 17% <br /> Basin Wildrye- 15% <br /> Needle&Thread-6% <br /> Rubber Rabbitbrush-5% <br /> • Seeding Rate: The seeding rate is set at 3.0 Pure Live Seed(PLS) per acre to ensure adequate coverage and soil binding. <br /> This mix is chosen for its resilience and effectiveness in local soil and climatic conditions of Colorado. <br /> • Silt Fences and Fiber Rolls: These are installed perpendicular to water flow to intercept runoff,trap sediment,and <br /> reduce runoff velocity. Fiber rolls,or erosion logs,made of organic materials help in capturing and breaking down <br /> sediment. <br /> s <br /> HARDROCK/METAL MINING REGULAR(112)APPLICATION Au Pt Industries LLC I PO Box 1424-Edwards,Colorado 81632 1970 306 1 784 <br />
