• Maintain the area by doing regular site inspections ensuring the establishment of vegetation and the eradication of alien invader species; and • Reinstate natural drainage patterns disrupted by mining wherever possible. All of the topsoil must be utilised as a growing medium in the rehabilitation process of the site, in other words it must be spread over all prepared areas (ripped to a depth of 300mm and sloped) and be re-vegetated with seeds found within the area or prepared in such a way as to satisfy the agricultural requirements of the area and/or the land owner. It is imperative that rehabilitation occurs concurrently with mining activities, as topsoil, containing seeds from plants within the area, degrades over time with the result that the soil environment becomes unfavourable for germinating seeds. 3.3 Closure processes The closure objective is to ensure that all the significant impacts have been mitigated against. All rehabilitated areas will be left in a stable, self sustainable state. Proof of this will be submitted at closure. The closure objectives for the Usutu opencast coal mine can be summarised as follows: • Make all areas safe for both humans and animals; • Make all areas stable and sustainable; • Ensure impact on any water bodies, water courses and catchment areas have been avoided or minimised; • Rehabilitate disturbed areas as soon as possible; and • Minimise the impact on the local community. With specific reference to the ground water environment, the following closure objectives should be pursued: • Rehabilitation of the surface infrastructure where necessary to minimize infiltration into the underground water regime (the philosophy of concentration and containment); and • Rehabilitation to minimise contamination of surface water resources (the philosophy of dilution and dispersion). When and if necessary suitable structures and or systems are to be put, and kept in place to limit contamination of water resources to concentrations in accordance with the Target Water Quality Ranges for human consumption. The goals upon decommissioning and closing of the Usutu opencast coal mine will include that all significant impacts have been mitigated and that there are no alterations to the environment that are apparent as far as is practically possible. All land will be rehabilitated to a state that facilitates compliance with current national environmental quality objectives including air quality objectives and water quality guidelines.

3.4 Storage of ore The Run of Mine stockpile will store a maximum of 80 000 ton of ore at any one time, at a steady state in the beginning, a stockpile will be built of up to 30 000 tons so as to start up the contractor. The topsoil and subsoil will be removed and stockpiled separately. Ore will be stockpiled near the processing plant on a pre-prepared area, where soils will be treated, compacted and provided with adequate Bitumen product to prevent seepage of acid drainage. The stockpile areas will be connected to evaporation ponds which will also be lined to ensure impermeability. Ore will be stockpiled for a maximum of two to three months, or until the operations at Portion 6A of the Farm Jan Hedriksfontein ends. The water collected in the evaporation ponds will be used for dust suppression on the mine. 3.5 Waste rock dump After the ore is extracted, waste rock will be placed on the waste rock dump by means of a conveyor belt. The waste rock dump will be positioned near the plant area. It is estimated that the ROM waste rock dump would be approximately 1 000 000m 3 . The footprint of the waste rock dump is calculated to be 600m by 800m with a height of 30m; therefore the total volume is estimated at approximately 14 400 000m 3 . The position of the waste rock dump is planned to reduce the initial hauling distance, at a position where it can be used to for the rehabilitation of the final void. EIA-REP-325d-11 October 2012 4. LEGAL FRAMEWORK FOR THE PROPOSED DEVELOPMENT This section includes a list of Acts applicable to this project and a brief description of the relevant aspect(s) of the relevant Acts. The aim of this component of the report is to provide a brief overview of the pertinent policies as well as legal and administrative requirements applicable to the proposed development of the Usutu Coal Colliery. The legislative motivation for this project is underpinned by the Constitution of South Africa (Act No. 108 of 1996), which states that: The State must, in compliance with Section 7(2) of the Constitution, respect, protect, promote and fulfil the rights enshrined in the Bill of Rights, which is the cornerstone of democracy in South Africa. Section 24 of the Constitution states: 24. Environment.-Everyone has the right- (a) to an environment that is not harmful to their health or well-being; and 50
