Mitigation: Action/Control Responsibility Timeframe Maintain marked sections of line in high sensitivity areas with anti-collision Eskom Operation marking devices (diurnal and nocturnal diverters) to increase the visibility of the power line and reduce likelihood of collisions. Marking devices should be spaced 10 m apart, and must be installed as soon as the conductors are strung mitigation, direct mortality through collision or area avoidance by the Eskom Operation species identified may still occur. Further research and mitigation for any problematic sections of line will be needed. Perching surfaces fitted with bird guards and perch guards as deterrents must Eskom Operation be maintained. Maintenance should remain within the development footprint and Eskom Operation movement outside these areas especially into avian micro-habitats must be restricted. Driving must take place on existing roads and a speed limit of 30km/h must be Eskom Operation implemented on all roads running through the study area during the construction phase. Maintain insulation of live components at support structures. Eskom Operation Performance Minimal collision or electrocution events. Indicator Monitoring Line inspections should be ongoing for the operational life of the line. Monitor power line servitude for mortalities OBJECTIVE 3: Minimise soil degradation and erosion The soil on site may be impacted in terms of: Soil degradation including erosion (by wind and water) and subsequent deposition elsewhere is of a concern across the entire site which is underlain by fine grained soil which can be mobilised when disturbed, even on relatively low slope gradients (accelerated erosion). Degradation of the natural soil profile due to pollution. Project Component/s Power line Access roads Potential Impact Soil degradation. Soil erosion. Increased deposition of soil into drainage systems. Increased run-off over the site. Activities/Risk Poor rehabilitation of cleared areas. Sources Rainfall - water erosion of disturbed areas. Wind erosion of disturbed areas. Concentrated discharge of water from construction activity. Mitigation: Ensure rehabilitation of disturbed areas is maintained. Target/Objective Minimise soil degradation (i.e. wetting). Minimise soil erosion and deposition of soil into drainage lines.
