The objective of the project is to develop a wind farm in order to generate electricity to feed into the national grid. The project is also in line with the government’s commitment to provide renewable energy as an alternative energy source to those currently utilized. Having received Environmental Authorisation (EA) for the EIA process, it is required that the EMPr is to be finalised and submitted to the Department of Environmental Affairs (DEA) as the determining authority for final approval prior to construction. A Final Environmental Management Programme (EMPr) is a detailed plan for the implementation of the mitigation measures to minimise the negative environmental impacts highlighted in the Final Environmental Impact Report (FEIR) (dated 13th April 2012). The Final EMPr will contribute to the preparation of the contract documentation between the Project Company and the contractor(s) that will carry out construction, by developing clauses to which the contractor(s) must adhere for the protection of the environment. The Final EMPr for the proposed project will include a construction environmental monitoring plan specifying how the construction of the project is to be carried out. The Final EMPr describes the mitigation measures that need to be undertaken to ensure environmental good practice during the pre-construction, construction, operational and decommissioning phases of the proposed project. The Noupoort Wind Farm (here after referred to as the proposed project) is located in the Northern Cape Province of South Africa and falls under the Umsobomvu Local Municipality in the greater Pixley ka Seme District Municipality, Northern Cape Province. Noupoort is approximately 53 km south east of the town of Colesberg, 35km north of Middelburg and 55km south west of Hanover town. The final layout of the Noupoort Wind Farm is shown in Figure i below. The Noupoort Wind Farm will have a capacity of 80MW and will consist of 35 wind turbines. The wind turbines will have a hub height of up to 120m. The rotor diameter will be up to 120m. The wind turbines will not be fixed and will be able to rotate to catch prevailing winds. The foundation of each wind turbine will be approximately 20m x 20m. The footprint for each wind turbine will therefore be approximately 400m². A hard standing area, of approximately 2 400m², for crane usage will accompany each wind turbine. Hence, the total footprint for each wind turbine and the associated hard standing area will be approximately 2 800m². The foundation will be up to approximately 2.5m deep. The wind turbines will be connected by underground cabling (approximately 1m deep) except where the cable cannot be buried. In this instance an overhead power line will be used. To connect the wind farm to the national electricity grid, a 132kV overhead power line will be constructed that will route from the substation on site towards the south west where it will tie into an existing 132kV overhead power line that routes into Noupoort. The power line will be approximately 13km in length. A substation will be constructed on the wind farm site which will occupy an area of 100m x 100m (approximately 10 000m²). An access road will be constructed that will be 6-10m wide. The roads will be gravel roads and will include turning circles for large trucks and passing points A temporary lay-down area is to be established which will be approximately 5 000m² (including an access route and contractor’s site). Other infrastructure will include an administration and warehouse building that will occupy an area of up to 5 000m². Figure i: Noupoort Wind Farm Final Layout The Project Company appointed SiVEST (Pty) Ltd to undertake and compile the Final EMPr in an effort to ensure environmental best practice by describing the mitigation measures that need to be undertaken to ensure environmental good practice during the pre-construction, construction, operational and decommissioning phases of the proposed project. This EMPr has been compiled in line with the recommendations in the above-mentioned FEIR, the Environmental Authorisation (EA), dated 29 October 2012 including subsequent minor amendments, from the DEA as well as from issues identified by SiVEST Environmental Division. Additionally, the following specialist walk-down studies as well as monitoring studies were undertaken and the proposed mitigation measures and recommendations were integrated into the Final EMPr (including final layout): . Twelve Month Avi-faunal Monitoring Assessment; . Twelve Month Bat Monitoring Assessment; . Avi-faunal Walk-down Assessment; . Biodiversity Walk-down Assessment; and . Heritage Walk-down Assessment. The EMPr has set out the conditions for the implementation of mitigation measures as well as the environmental management for all personnel involved in the project. The stipulated mitigation measures are described in detail for the per-construction, construction, operational and decommissioning phase of the proposed project. It also outlines the roles and responsibilities of all personnel involved in the proposed project.
