M.Sc. / The Merriespruit Tailings dam disaster killed seventeen (17) people and covered a part of Virginia with approximately 2.5 million cubic metres of tailings, causing such an emotional uproar that all resources were focused on repairing the dam and addressing some of the social issues. Little attention was given to the environment. The identified need in this study was therefore to investigate the consequences of the disaster on the environment, a need which derives from the uniqueness of this particular disaster and its consequences. The Department of Minerals and Energy require the submission of an Environmental Management Program Report (EMPR) on all prospecting and mining operations. It is clear that, in the compilation of such an EMPR, Harmony Gold Mine neglected to establish a Management Plan to regulate the physical impact of the disaster on the environment, mainly because no attention was given to disasters in the Aide-Memoir. A Management Plan was established by adapting existing formats of management plans to the uniqueness of this disaster. By following the procedure stipulated in the Management Plan it can be ensured that Environmental Management requirements will be effectively integrated into either the project management actions and contracts or operational systems and processes for the following issues: • Water management • Storm water control • Waste management • Dust • Aesthetics and socio-economic implications • Rehabilitation of the area. The investigation showed that the disaster exerted a definite negative influence on the environment, which can be managed by taking preventative measures stipulated in the Management Plan. However, one of the main issues identified in this study is that storm water management has been problematic for a period of time. It is therefore noted that some attention should be given to establishing a wetland system to contain the storm water runoff. Although this study does not focus on the socio-economic impacts in detail, it is recommended that these impacts are considered as it is evidently problematic. The primary aim of this study was to compile an EMP in order to manage, and possibly mitigate, the physical impact of the disaster on the immediate environment, an aim which clearly was accomplished. Harmony Gold Mine can benefit from the compilation of this EMT, as management goals were set and feasible means of achieving them were specified.
