Addendum to <strong>EMPR</strong> for Concessions 8(a), 9(a) and 8(b) 40Mitigation Measures and Management ActionsManagement actions should include:- Maintain high safety standards and employ “good housekeeping” onboard the vessel.- Ensure that stringent waste management practices are in place onboard vessels.- Ensure that oil spill contingency plans, adequate insurances and internationallyaccepted onboard environmental management systems are in place for the miningvessels. These should incorporate plans for emergencies.4.3.6 Onshore Gravel ProcessingThe land-based operations associated with the project will be located in Sand Bay to the southof the town of Hondeklipbaai, and will extend from a few metres to a few hundred metresinshore of the high water mark.The reclamation dam, processing facility and associated infrastructure will be located withinthe non-operational Hondeklipbaai Mine property managed by the Trans Hex Group. Theterrestrial footprint of the project is therefore embedded in previously disturbed areas, and inmost cases will utilise existing infrastructure.The gravel processing and accommodation facilities at Hondeklipbaai fall into the Spoeg Rivercatchment area. As fresh water consumption at the plant site and accommodation facilitieswill be restricted to that necessary for domestic use, the fresh water demand is thusinsignificant. No watercourse is impacted by the operations of the gravel processing facility.Tailings from the processing facility will be transported by truck and trailer to an old miningexcavation on the Hondeklipbaai Mine. As vehicles will use mainly tertiary gravel roads, theimpact of gravel-transporting vehicles on existing traffic densities is negligible. Public usage ofthese roads is limited, and interaction between mining vehicles and other traffic is thereforeinsignificant.Construction of Treatment Plantand Reclamation AreaConstruction will be accompaniedby:- the clearing of vegetation, soiland associated biota,- potentially impacting localisedpopulations of endemic and nearendemicplant species,- establishment of infrastructure(treatment plant and offices,power, water and fuel supply,handling and storage),- visual impacts of associatedinfrastructure, reclamation pond,tailings heaps etc.StatusProbabilityConfidenceExtentDurationIntensitySignificanceNegativeHighly probable; although the area isalready severely disturbed, establishedvegetation is present.HighSite-specific.Medium- to Long-term; restoration ofdisturbed areas and successful restorationof plant communities usually takes >1 year,even where intervention is intensive.Mild; although the total area of vegetationaffected is relatively large, the vegetationand soils have already been impacted.LowNamagroen Prospecting & Investments October 2008
