February 2011 118 12619ÜÜÜÜÜÜÜÜAll alien invasive species on site should be removed and follow up monitoring and removalprogrammes should be initiated once construction is complete;All construction and maintenance activities should be undertaken in accordance withEskom Transmission’s environmental best practice standards.Care should be taken not to unnecessarily disturb any birds along the servitude.The Environmental Control Officer should identify any sensitive along the servitude,particularly large terrestrial species and notify the fauna specialist of these so that advicecan be given on how to best deal with the situation.The construction of new access roads in particular should be limited to a minimum.All vehicle and pedestrian movement should be restricted to the actual construction siteand, in the case of maintenance patrols, to the actual servitude.Adhere to the ESKOM vegetation management guideline; andInstall power lines according to the ESKOM bird collision prevention guideline.Residual ImpactThe mitigation measures proposed above will ensure that the construction of the proposed powerline remains a Moderate impact but the Residual Impact remains High.12.1.4 Surface Water and WetlandsSurface water features are demarcated as sensitive because of the high variety of fauna and florathat occur in such areas. Areas such as rivers, dams and wetlands provide habitats for many plantand animal species that are endangered, which makes these areas very sensitive and of a highconservation value.Initial ImpactThere are a number of streams and drainage lines that have been dammed which may havecaused damage to downstream aquatic life. The presents of agriculture and urban areas will alsohave had an affects on surface water flow. The construction of the existing power lines have hadminimal affect on surface water flow, as they span most of these features.Table 12-9: Surface water Initial Impact Rating ScaleImpact Significance Spatial Scale Temporal Probability RatingScaleImpact to VERY LOW Isolated sites / Medium Could LowSurfacewater1proposed site1Term3happen3 1.6ZITHOLELE CONSULTING
