The height of each cell at any given point in time will depend on therelative rates at which material is deposited and removed for beneficial use.The worst case scenario would develop if:• No beneficial uses are developed for any of the materials and all the cells continuegrowing in height until the design storage capacity of the Boitshepi Waste Disposal Siteis reached and the facility has to be closed due to a lack of storage space for additionalmaterial.Alternative 1: Extension of the waste disposal site footprint with a 0 metre buffer zone (nodistance between waste disposal site and surrounding land users). The significance of thevisual impact without mitigation is assessed as high for alternative 1.Alternative 2 and 3: Extension of the waste disposal site footprint with a 50 metre or 100metre buffer zone. The impact will therefore be MODERATE to LOW and will be in the longterm.ZITHOLELE CONSULTING
