Significance With Mitigation (WM) EIA-REP-325d-11 October 2012 127 MEDIUM Source of impact: Mining activities and construction of an access road during the Operational Phase Description of impact: Wetland habitat in the region of the study site shelters several sensitive faunal and invertebrate species. Cumulative disturbance of the natural vegetation cover in the wetland areas and also in the surrounding landscape will result in the eventual loss of this habitat type, and consequently to the loss of the species dependant on the vegetation cover. Significance: The overall significance of the impact on the wetland habitats is considered to be medium after the implementation of mitigation measures. Mitigation: • No mining activities should take place within buffered the wetland areas or in their associated buffer zones. • Wetland areas and their associated buffer zones should be fenced during the construction phase to prevent any human activity from encroaching onto these areas. • Wetland areas outside the study area that are affected by access to the site by machinery and the labour force should also be fenced off and protected. • No animals may be trapped, hunted or handled in any way. • No vegetation may be collected or used for firewood.

Source of impact: Mining activities during the operational phase. Description of impact: The location of the study site in relation to the catchment area of water bodies surrounding the study site mean that the proposed coal mining activities potentially expose surrounding water users to severe water quality concerns. The significance of this potential impact should be quantified by means of a detailed geohydrological assessment which describes the hydrological linkages between pans and regional aquifers. Significance: The overall significance of the impact on the hydrological regime is considered to be medium after the implementation of mitigation measures. Mitigation: • In order to minimise artificially generated surface stormwater runoff, total sealing of paved areas such as parking lots, pavements and walkways should not be permitted. Permeable material should rather be utilized for these purposes. • Establish water quality parameters before mining activities commence which can serve as future benchmark data against which regular water quality monitoring can be measured to determine the impact of the mining activities on the regional aquatic resources. • Implement an ecologically-sensitive stormwater management plan that includes not allowing stormwater to be discharged directly into the identified buffer zone of the wetland area. 13.2 Air quality 13.2.1 Air Quality deterioration Table 24: Assessment of the possible impacts on air quality during the construction and operational phase Atmospheric pollution associated with coal transport, waste stockpiles, uncontrolled Activity spillages, disturbed land and vehicles on un-surfaced roads.
