93August 2010 884811.1.4 Surface waterInitial ImpactThe initial impact to surface water was investigated visually and no surface water sampleswere taken. An impact to surface water would have a HIGH significance locally in the shortterm and therefore the initial impact is rated as Moderate.Additional ImpactDuring construction vegetation clearing will take place exposing the soil to erosion elementsthat could potentially be washed into local surface water bodies resulting in an increase inturbidity and sedmentation of local resources, particularly the vlei to the south of the site.Additionally heavy vehicles will be present on site with the potential for hydrocarbon spillageand leakeage. The impact is therefore of a HIGH significance that could occur duringconstruction in the short-term, therefore the impact is rated as a Moderate impact.Cumulative ImpactThe cumulative impact will remain as assessed in the initial and additional sections.Mitigation MeasuresThe following mitigation measures are proposed during construction:• Divert storm water through sediment traps and then divert all water with cut-off drainstowards established trenches.• Ensure that all machinery on site is in a good working order and does not have leaks;• Hydro-carbons should be stored in a bunded storage area or in designated facilities atthe Boitshepi Waste Disposal Site;• No efueling shall take place on site;• No maintenance of machinery to be done on site, but to be done at the site’s demarcatedarea for this;• Spill-sorb or a similar type of product must be used to absorb hydrocarbon spills in theevent that such spills should occur;• Care must be taken to ensure that in removing vegetation adequate erosion controlmeasures are implemented;• Ensure that storm water control measures are incorporated into the waste disposal sitedesigns prior to the start of construction;ZITHOLELE CONSULTING
