123August 2010 884811.3 Decommissioning Phase11.3.1 Soils and Land CapabilityInitial ImpactThe initial impact remains as assessed in Section 11.1.1, a High impact.Additional ImpactDuring the rehabilitation and closure phase the waste disposal site will be capped. Even withproper rehabilitation, the soils will never completely recover unless the waste material isremoved from the site. However the additional impact at this stage is a Low – Positiveimpact. This impact rating will be the same for all three alternatives but due to the smallerfootprint from Alternative 3, this alternative will have the least impact on soil. Soils will beimported to the site and the site will be re-vegetated.Cumulative ImpactThe cumulative impact during the decommissioning phase remains as assessed in section11.1.1 since the additional impact and the initial impact occur in the same area. Thereforethe impact remains a High impact.Mitigation MeasuresThe mitigation measures remain as assessed in Section 11.1.1 for all three alternatives.Residual ImpactThe residual impact during the decommissioning phase remains as assessed in 11.1.1.Therefore the impact remains a Moderate impact.Table 44: Impact Rating Matrix for Soils during the Decommissioning Phase.Type of Significance Spatial Temporal Probability RatingImpactInitial VERY HIGH Study site Long Term Is Occurring 3.7- HighAdditional LOW IsolatedsitesLong Term Could occur 1.3- Low –PositiveCumulative HIGH Study site Long Term Will occur 3.3- HighResidual HIGH Study site Long Term Very Likely 2.7- ModerateZITHOLELE CONSULTING
