eadily dispersed with no significant impact on the marine ecology. Similarlyin the event of exposure of cement directly into the marine environmentany chemical pollution is expected to be readily dispersed with and impactsare expected to be of low significance to the marine ecology in the area.Potential impacts from this source will need to be mitigated by providingneighbouring abalone farms with adequate warning regarding the timing ofall casting, and blasting activities such that they can be on standby and cantake appropriate action (e.g. temporarily turning off intake pumps) in theevent of an accident (e.g. spillage of wet concrete directly into the sea).The construction activities will involve the use of heavy vehicles andmachinery in the coastal zone and there is a potential for hydrocarbonspills. Suitable management mechanisms must be implemented to mitigatethis risk and contingency plans in the event of accidental spills must beprepared. This should include measures required to ensure that no stormwater from the site be allowed to enter the sea.StatusExtentDurationIntensityProbability ofoccurrenceCumulative impactprior to mitigationSignificance prior tomitigationDegree to which impactcan be mitigatedProposed mitigationProbability ofoccurrence withmitigationCumulative impact withmitigationSignificance withmitigationNegativeLocalMedium termMediumProbableLowLOWLow All fuel and oil is to be adequately stored and no leaking vehicles are tobe permitted on site.
