Project Details Page i EMP AMENDMENT FOR GROOTEGELUK COAL MINE, LIMPOPO PROVINCE: Environmental Impact Assessment and Environmental Management Programme June 2010 PURPOSE OF THE EIA & EMP REPORT In order to adequately provide for the growing electricity demand within South Africa, Eskom Holdings Limited is in the process of constructing a new coal-fired power station southwest of the existing Matimba Power Station in the Lephalale area. This power station is to be known as the Medupi Power Station and will have a maximum installed capacity of 4 800 MegaWatts (MW). Coal to fuel the Medupi Power Station will be provided to Eskom from the Grootegeluk Coal Mine by Exxaro Resources (Pty) Ltd. The Grootegeluk Coal Mine is an existing mine (Mining Right Reference No.: 5/3/2/50) located in the Limpopo Province approximately 21 km west of the town Lephalale on the farms Grootegeluk 459 LQ, Hierontrent 630 LQ, Leeuwdrift 312 LQ, Enkelbult 462 LQ, Daarby 485 LQ and Turfvlakte 463 LQ (refer to Figure 1.1). In order for Grootegeluk mine to supply coal to the new Medupi Power Station, the following will be constructed by Eskom: » A coal silo at the mine. » A coal feed conveyor belt between the mine and the power station. This conveyor will cross the Farm Turfvlakte for which Exxaro hold the prospecting and mining rights. » An access road to be utilised during construction and operation of the coal silo and conveyor. In terms of the Minerals and Petroleum Resources Development Act (MPRDA; Act No. 28 of 2002) and National Environmental Management Act (NEMA; Act No. 107 of 1998), Exxaro is required to undertake an Environmental Impact Assessment (EIA) process to amend the mine’s current approved Environmental Management Programme (EMP) to include the coal silo, coal conveyor and access road. The EIA undertaken for the power station included an assessment of the coal conveyor. This study will therefore be used as the basis for the EMP amendment process required to be undertaken in accordance with the MPRDA. The first phase of an EIA was the Scoping Phase, during which issues associated with the proposed development were identified and evaluated to highlight the significant issues that may require further investigation and assessment in the EIA. The purpose of this EIA and EMP Report provides an assessment of these potential impacts as well as recommends management measures for the mitigation of these impacts. Purpose of the Scoping Report Page ii EMP AMENDMENT FOR GROOTEGELUK COAL MINE, LIMPOPO PROVINCE: Environmental Impact Assessment and Environmental Management Programme June 2010 This EIA and EMProgramme Report consists of the following sections: Part 1: Background to the Project » Chapter 1 provides background to the proposed project and the EIA process » Chapter 2 provides an overview of the proposed project » Chapter 3 outlines the EIA process which was followed for the proposed project Part 2: Environmental Impact Assessment » Chapter 4 provides a description of the environment which may be potentially affected by the proposed project » Chapter 5 provides an assessment of the potential impacts associated with the proposed project, including recommendations for mitigation of potentially significant impacts and an impact statement regarding the proposed project Part 3: Environmental Management Programme » Chapter 6 presents the Environmental Management Programme, including details of the planned monitoring and environmental management for the construction and operation of the conveyor and associated infrastructure Appendices: Includes technical and supporting documentation, including specialist reports undertaken for the EIA and EMP.
