EIA-REP-325d-11 October 2012 14. CUMULATIVE IMPACTS (Reg 31(2)(l)) Cumulative impacts as illustrated below, occur because of the combined effect of incremental changes caused by other activities together with the particular project. In other words, several developments with insignificant impacts individually may, when viewed together, have a significant cumulative adverse impact on the environment. Development Development Impact 1 Impact 2 Figure 15: The identification of cumulative impacts The following cumulative impacts have been identified in terms of the proposed development: • Cumulative impacts on traffic as a result of more heavy vehicles making use of the roads in the immediate area; • Cumulative impact: decrease in air quality in the immediate surroundings of the mine • Cumulative loss of wetland functionality as a result of an increase in pollutants; • Cumulative impact on wetland function and ecology; • Cumulative impact of hydrological modifications and stormwater; • Cumulative impact of faunal habitat and displacement; • Cumulative impact on natural migratory routes and faunal dispersal patterns and • Cumulative impacts on the decreased quality of the water sources in the area as a result of contaminants being released into water sources. 14.1 Cumulative impact: increased traffic volumes within the mine and surrounding communities Source of impact: Traffic will increase in and around the proposed development. The increase of especially heavy vehicles movements surrounding the Vunene Colliery (Pty) Ltd project, such on National and Provincial roads which are in the vicinity of the mining complex and link up to the project area. In addition to this traffic within the mine area itself will also be a contributing fact towards cumulative impacts from an increase in traffic. Description of the impact: The proposed development entails the set up of mining activities as well as the construction of mine related infrastructure. Due to the nature of the activity it is likely that there will be a cumulative increase in vehicular traffic within the mine and just outside the boundary of the mine. The cumulative impacts emanating from the increase in traffic may become apparent during the operational phase of the Usutu opencast and underground coal mine. Temporary access roads could also contribute significantly to dust impacts, spills and erosion and loss of soil resources. 155 Impact A
Significance of impact: The transport of materials, people and goods may present the only significant impact. The movement of vehicles on the local roads within the surrounding communities may result in damage to roads from movement of heavy vehicles. Despite the potential cumulative impacts from the traffic increase it is not anticipated that the impact will have a ranking higher than medium for as long as the internal road are not in close proximity to the adjacent communities. As long as the roads are internalised, it is not anticipated that the cumulative impact of traffic will be significant. Mitigation: • Only main roads should be used; • Where feasible vehicles should not operate on public roads during peak hours; • Vehicles should adhere to the speed limit of the road; • Heavy vehicles should always travel with their head lights switched on; • Heavy vehicles should not stop on the road to pick up hitchhikers – No stopping on the road approaching the mine will be allowed; • Limit the extent and degree of change to the biophysical and socio-economic environment; and • Communicate with and acknowledge concerns of the I&APs and mitigate where possible. 14.2 Cumulative impact: decrease in air quality in the immediate surroundings of the mine Source of impact: • Materials handling operations with mining are predicted to result in significant fugitive dust emissions including the transfer of material by means of tipping, loading and off-loading trucks; • Wind erosion from exposed areas – significant emissions arise due to the mechanical disturbance of granular material from open areas and storage piles; • Primary washing and drying operations represent significant dust generating sources if uncontrolled; • Particulate emissions will result from the entrainment of loose material from the paved road surface due to the vehicle traffic. Description of impact: Dispersion simulations should be executed for the proposed operational phase. Previous experience with coal mines indicated that PM10 and TSP should be assessed. The predicted concentrations for these pollutants are discussed below. In order to account for cumulative impacts, measured PM10 concentrations from the mines surrounding the Ermelo community should be used. The annual average concentration of 52µg/m 3 is used to reflect the background concentrations at the Usutu opencast and underground coal mine. PM10 The predicted mitigated daily average ground level concentrations for the proposed operations at the Vunene Colliery (Pty) Ltd facility do not exceed the daily current South African standard of 180µg/m 3 or the proposed South African standard of 75µg/m 3 at the mine boundary or the sensitive receptor sites.
