The “Emergency/Risk Mitigation Power Purchase Procurement Programme (2000MW): National” has also been designated the status of a Strategic Integrated Project (SIP) under the Infrastructure Development Act, 2014 by the Presidential Infrastructure Coordinating Commission. SIPs are considered to be projects of significant economic or social importance to South Africa as a whole or regionally that give effect to the national infrastructure plan and for this reason, can be expeditiously implemented through the provisions of the enabling Act. At the time of this report, the preferred bidder status had not been confirmed. The Karpowership project will generate electricity from two floating mobile Powerships moored in the Port of Ngqura. Three ships will be berthed at any one time, during the project’s 20 year lifespan (as per the RMIPPPP requirements) - a Floating Storage Regasification Unit (FSRU) and two Powerships. A Liquefied Natural Gas Carrier will supply the Liquefied Natural Gas (LNG) to the FSRU over a one-to-two day period approximately every 20 to 30 days. The LNG is then converted to Natural Gas (NG) and pumped from the FSRU to the Powership via a gas pipeline. The proposed design capacity for the Powerships is 540MW, which comprises 27 gas reciprocating engines having an approximate heat input of over 10MW each. The three steam turbines have a heat input of 15.45MW each. The power that is generated is then converted by the on-board High Voltage substation and the electricity evacuated via a 132kV transmission line over a distance of approximately 7.5km to Eskom Dedisa Substation which feeds into the national grid. Two alternative mooring sites are being considered. The first option is to position the two Powerships in a closer position to the transmission line on land. The second is to position the two Powerships further away from the land and the connection to the transmission line. The depth of the water in which the ships will be positioned is approximately 14m. The gas pipeline that connects from the FSRU to the Powerships will be routed along small portions of the seabed but predominantly on the eastern side of the breakwater. From one of the Powerships, an electricity tower and lines will connect to a sub-station and into the national grid. The Project triggers a number of activities listed under the National Environmental Management Act 107 of 1998 (NEMA) which require environmental authorisation prior to commencement. Because these listed activities include activities described in the Environmental Impact Assessment (EIA) Regulations Listing Notice 2 of 2014 (as amended), the process that is required to be applied to the application for environmental authorisation is Scoping and Environmental Impact Reporting (S&EIR). The procedural requirements for S&EIR are set out in the EIA Regulations, 2014 (as amended). Scoping has already been concluded with the acceptance of the Scoping Report, including the plan of study for the EIA by the competent authority, namely the Department of Environment, Forestry and Fisheries (DEFF) on 6 i January 2021. This draft EIA Report is part of the EIR phase and has been distributed for comment for a 30-day period as part of the public participation process. The objectives of the EIA process is, through a consultative process with Interested and Affected Parties (I&APs), including relevant organs of state, to: determine the policy and legislative context within which the activity is located and document how the proposed activity complies with and responds to the policy and legislative context; describe the need and desirability of the proposed activity, including the need and desirability of the activity in the context of the development footprint on the approved site as contemplated in the accepted scoping report; identify the location of the development footprint within the approved site as contemplated in the accepted scoping report based on an impact and risk assessment process inclusive of cumulative impacts and a ranking process of all the identified development footprint alternatives focusing on the biophysical, social, economic, heritage and cultural aspects of the environment; determine the- nature, significance, consequence, extent, duration and probability of the impacts occurring to inform identified preferred alternatives; and degree to which these impacts can be reversed; may cause irreplaceable loss of resources, and can be avoided, managed or mitigated; identify the most ideal location for the activity within the development footprint of the approved site as contemplated in the accepted scoping report based on the lowest level of environmental sensitivity identified during the assessment; identify, assess, and rank the impacts the activity will impose on the development footprint on the approved site as contemplated in the accepted scoping report through the life of the activity; identify suitable measures to avoid, manage or mitigate identified impacts; and identify residual risks that need to be managed and monitored. The EIA process, including public participation, and findings are reported on in the draft EIA Report, in particular, Chapters 7, 8 and 9. Once the public participation process has been concluded, the draft report will be revised taking into consideration the I&APs’ comments. The Final EIA Report will then be submitted to DEFF for consideration, and a decision either to grant or refuse environmental authorisation will be made. All registered I&APs will be notified of this decision and of their opportunity to appeal. The following issues and potential impacts have been identified and assessed in respect of the various alternatives in the EIA: Powerships and FSRU and Liquefied Natural Gas Carrier (LNGC) Disturbance to marine habitat; Disturbance to the sediment from mooring infrastructure; Reduction in ambient air quality from increased atmospheric emissions; Safety risk from potential leakage of LNG; Safety risk of storage of NG within the Port; Increase in noise pollution; Change in water temperature ii Provision of additional electricity; Contributions to climate change; Socio-economic impacts; Marine traffic congestion and accidents; Visual Impacts Gas Pipeline Disturbance to marine and estuarine habitat; Impact on coastal environment; and Potential leakage of LNG. Transmission Line, Switching Station and Temporary laydown area for gas pipeline installation Impacts on indigenous vegetation and species of conservation concern; Disturbance to the terrestrial ecosystem; Impacts on fauna and avifauna; Altered hydrology and geohydrology; Impact on aquatic system; Increase in noise pollution; Change in hydropedological processes; Destruction of wetlands, watercourses, estuarine areas; Destruction of cultural heritage and palaeontological resources; Disturbance to properties and existing services; and Provision of additional electricity. Visual Impact The assessment was conducted with specialists’ input, and includes the identification of mitigation measures and an evaluation of their effectiveness. These assessment findings are used to determine the preferred alternatives and provides the basis for the EAP’s opinion as to whether the proposed activity should be authorised or not, and if so, the conditions that should be made in respect of such authorisation. Should authorisation be granted, the applicant will need to comply with the Environmental Management
