The process that was followed complies with Sections 21 and 26 of the Environment Conservation Act (Act No. 73 of 1989, as amended). This is the second stage of the EIA process, which involves a comprehensive environmental impact assessment aimed at evaluating all the significant environmental and socio-economic impacts of the proposed transmission line on the surrounding environment. This report investigated the study area, and evaluated various servitude corridors for the transmission line. A preferred corridor for the transmission line was recommended. GENERAL PROJECT DESCRIPTION Eskom proposes to develop a 400 kV transmission line to provide additional capacity to support the 400 kV network supplying the Greater Cape Region south of Bloemfontein. The application entails a proposal to secure the required servitude for the said transmission line in advance, prior to the actual construction of the line. The proposed servitude for the transmission line will be approximately 250 km in length and will occupy about 1375 ha. The underlying philosophy is to develop the transmission line within the selected corridor that takes into account the physical, biological and social environments. To this effect, three feasible alternative corridors within the entire study area were identified. I&APs proposed a fourth alternative during the public participation process. A team of specialists examined all four alternative corridors comprehensively to determine which would have the least physical, biological and socio-economic impacts. One of the proposed alternative corridors will be selected as the preferred corridor wherein the 55 m servitude can be negotiated by Eskom. THE NEED FOR THE MERCURY - PERSEUS 400 KV TRANSMISSION LINE The additional power is needed to electrify the proposed Coega Industrial Development Zone (IDZ), which is situated in the Eastern Cape Province, 20 km from Port Elizabeth. The Coega IDZ will include commercial and industrial activities, foremost of which is a new aluminium smelter that requires guaranteed energy supply. The Eastern Cape has a significant unemployment rate, which is observable in terms of the rural and urban population distribution, with statistics indicating that unemployment is greater in some urban areas. There is therefore a need to promote employment-generating initiatives in the region. To appreciate the need for the new line from a national economic viewpoint, it is necessary to briefly explain the strategic advantages of having a new transmission line to the Eastern i Prepared by Strategic Environmental Focus Eskom Transmission Mercury – Perseus 400 kV transmission line Environmental Impact Report Cape region and the potential long-term impacts of the transmission line through the region. The positive impacts of the transmission line at a regional scale also need to be seen in view of the Coega development. The Coega IDZ is to be implemented in a phased approach, and will include, among others, land uses such as businesses, commercial industrial areas, bulk import/export facilities, metallurgical areas and open spaces. A key requirement for the success of these developments proposals is the supply of power. The existing power supply network to the greater Port Elizabeth area is already considered to be unstable, and load-shedding schemes are installed. The Nelson Mandela Metropolitan Municipality has thus approached Eskom Transmission, in consultation with the Coega Development Corporation (Pty) Ltd (CDC), to provide additional power to supply the proclaimed Coega IDZ and the associated Port of Ngurha. Eskom as a major role player in the Coega Development Corporation (CDC) plans to electrify the Coega Industrial Zone (IDZ) and its associated port in the Eastern Cape, through the establishment of appropriate infrastructure. Aluminium Pechiney, the potential anchor tenant of the Coega IDZ, has recently confirmed its decision to proceed with the construction of a new aluminium smelter. One of the main criteria in the selection of the final site was the availability of guaranteed energy supply. The operation of an aluminium smelter within the Coega IDZ will require approximately 860 MW of electricity. The construction of a 400 kV transmission line will not only meet the energy supply requirements of potential Coega IDZ tenants, but will also strengthen the 400 kV network supplying the Greater Cape Region south of Bloemfontein. This will in turn secure South Africa’s national electricity grid, and in the long run contribute to national macro-economic growth. PUBLIC PARTICIPATION PROCESS A comprehensive public participation process for the EIA was a crucial mechanism that attained several goals. It informed the public and Interested and Affected Parties (I&APs) about the need for the new Transmission Line. The process was also the forum through which issues, concerns, needs and requirements of I&APs were elicited as input into the EIA. The public participation process was aimed at allowing the public to participate meaningfully and be involved at an early phase of the environmental process right from the Scoping phase and throughout the EIA. Through a process of stakeholder identification and involvement several I&APs were identified and subsequently notified of the project by various means. A number of public focus group meetings and public meetings were held in the main towns within the study area. These meetings were informative and constructive, giving I&APs an opportunity to raise concerns in a small-group environment. These concerns are addressed within this report. ii Prepared by Strategic Environmental Focus Eskom Transmission Mercury – Perseus 400 kV transmission line Environmental Impact Report The objectives of the public participation process included: • The development of a database of key stakeholders and I&APs; • The facilitation of a focussed public involvement and consultation process to ensure that I&APs contribute meaningfully to the EIA process and share information; • The investigation of the issues, concerns and corridor alternatives raised by I&APs; and • To function as an on-going data-gathering exercise that informs the EIA, the specialist studies, as well as the development of mitigation measures. A Website for the Mercury – Perseus EIA ([email protected]/eia) was set up and made accessible from 4 April 2003. The Website not only provided background information on the EIA process and the project, while allowing I&APs to register their interest / concerns, but also gave them an opportunity to ask questions and provide comments. Minutes of all public and focus group meetings are also available at this Website. A Background Information Document (BID) was developed and distributed to all I&APs. The BID was made available at the Open Days, Focus and Public Meetings throughout the EIA. The document contained information regarding the EIA process, the proposed transmission line and the Team of Consultants involved. Initial Public Meetings The first Open Day / Public Meeting took place on Wednesday 23 April 2003 at Bultfontein, while the second was conducted on Thursday 24 April 2003 at Bothaville. These meetings were the forum for informing the public of the details of the proposed transmission line as well as giving feedback on how issues raised by members of the public would be addressed in the EIA. Invitations to public meetings were sent to all parties registered on the I&AP database. Issues Register Issues and concerns raised by I&APs during the scoping exercise (January to June 2003) were captured in a draft issues register, which was included in Appendix 3 of the Scoping Report (dated 25 June 2003). Comments from potentially affected parties were received from the public throughout the EIA phase of the project. The Issues Register was subsequently updated and incorporated into Appendix A5 of the Draft EIR. Focus Group Meetings Several meetings were held in small groups with key stakeholders throughout the EIA process. These meetings were important channels through
