August 2010 40 8848The approval letter received from the GDARD from the Scoping Phase stated thatAlternative 3 (100 metre buffer) was the preferred alternative, and at that stage alternative 3would allow for an additional 3 years airspace. This is no longer the situation and the threealternatives have been re-evaluated as follows:• Alternative 1: Extension of the waste disposal site footprint with a 0 metre buffer zone(no distance between waste disposal site and surrounding land users), the site will havean additional 3,221,113 m³ of airspace available with an additional estimated lifespan ofapproximately 8 years;• Alternative 2: Extension of the waste disposal site footprint with a 50 metre buffer zoneThe site would gain an extra 2,576,113 m³ of airspace and have an additional lifespan ofapproximately 6-7 years; and• Alternative 3: Extension of the waste disposal site footprint with a 100 metre buffer zone.An addition of 710,475 m³ airspace would be available and the expected additional life ofthe waste would be approximately 1-2 years.Alternative 3 initially seemed viable and preferable, with the smallest footprint for theproposed extension as an intermediate solution prior to the new waste disposal beingestablished. However, on evaluation of the recent calculations it is evident that thisalternative is no longer feasible since it will not accommodate the disposal requirements forthe area until the new site is commissioned and it is therefore no longer the preferredalternative but is fatally flawed. Regardless of this fatal flaw it is included in the impactassessment for consistency and information purposes.The three alternatives are illustrated in Figure 10.ZITHOLELE CONSULTING
