August 2010 39 88486 TECHNOLOGY REVIEW / ALTERNATIVES CONSIDEREDThe Integrated Environmental Management (IEM) Guidelines (DEA) state that information onreasonable alternatives should be provided. The following alternatives have been consideredand are discussed in more detail below:• Site alternatives;• Design alternatives; and• “No-go” alternative.Alternatives are different means of meeting the general purpose and need of a proposedactivity. Alternatives may involve location (site), activity, process or technology, temporal orthe no-go alternatives. Alternatives relevant to the project have been detailed below.6.1 Site AlternativesThere are no site alternatives as the activity is for the extension and decommissioning of anexisting site. It is proposed that the current waste disposal site be upgraded and extendedwith the view to closure.6.2 Design AlternativesThree different design alternatives were considered in the Scoping Phase of the project(2008). The three alternatives were 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 3,651,113 m³ of airspace available with an additional estimated lifespan ofapproximately 9 years;• Alternative 2: Extension of the waste disposal site footprint with a 50 metre buffer zone.The site would gain an extra 3,006,113 m³ of airspace and have an additional lifespan ofapproximately 7-8 years; and• Alternative 3: Extension of the waste disposal site footprint with a 100 metre buffer zone.An addition of 1,140,475 m³ airspace would be available and the expected additional lifeof the waste would be approximately 3 years.The EIA for the proposed Boitshepi Waste Disposal Site was initiated in January 2007. Theproject has been on-going for almost three years and throughout this period waste has beenand continues to be disposed of at Boitshepi. As a result some of the information that hasbeen provided in earlier phases of this project is outdated and no longer applicable,therefore certain capacity and lifespan calculations are no longer correct and out byapproximately two years and required re-evaluation.ZITHOLELE CONSULTING
