a medium significance even though the impact will not be reversible and is of a permanent nature. Temporary wetland zones that are still impacted are former agricultural lands that have no biodiversity value. Mitigation • Development should not be considered within wetland boundaries and their associated buffer zones; • Interventions and mechanisms should be included in the proposed development to reduce the impact of stormwater on the wetland; • An ecologically sensitive stormwater management plan will be required to attenuate flood peak events and prevent excessive erosion; and • The natural open spaces in the proposed layout should be connected to adjacent natural open spaces. 14.5 Cumulative impact of hydrological modifications and stormwater Source of the impact: Hardened surfaces will impact negatively on the wetlands, as the construction of impermeable layers on the surface will prevent infiltration and ultimately result in reduced seepage yields. Description of the impact Increased stormwater runoff with an associated increased erosion potential are also directly related to the expansion of hardened surface inside a catchment. Interventions and mechanisms can be included in the development to facilitate a higher percentage of infiltration (e.g. porous pavements). Significance The significance of the impact is expected to be of a medium significance without mitigation, this due to removal of vegetation and the construction of hard surfaces. With mitigation the significance of the impact will be of a low significance even though the impact will not be reversible and is of a permanent nature. Mitigation • Development should not be considered within wetland boundaries and their associated buffer zones; • Interventions and mechanisms should be included in the proposed development to reduce the impact of stormwater on the wetland; • An ecologically sensitive stormwater management plan will be required to attenuate flood peak events and prevent excessive erosion; and • The natural open spaces in the proposed layout should be connected to adjacent natural open spaces. 14.6 Cumulative destruction of sensitive habitat Source of the impact: Development of sensitive habitat types and the impact of development on sensitive habitat types, such as road infrastructure etc. This will result in the fragmentation of species and habitats associated with important landscape elements such as wetlands and ridges that function on a landscape scale as corridors. EIA-REP-325d-11 October 2012 159
Description of impact: The most sensitive habitats of ecological significance on the site are the riverine habitats and the rocky outcrops and associated steep slopes. If impacted they will deteriorate downstream use and water quality and impact on the hydrology of the site. Impacts will also affect natural faunal migration and movement down these linear systems which act as corridors in the landscape. From an ecological point of view it is also very important that this report is taken into consideration when planning and layouts are determined. These sensitive areas have been demarcated as part of the specialist studies. There is no development on rocky outcrops, footprints are minimal, and therefore impact without mitigation is medium. Significance The significance of the impact is expected to be of a high significance without mitigation, this due to the destruction of sensitive habitats that support a high ecological functioning site to allow for the mining of the proposed development. With mitigation the significance of the impact will be reduced to that of a medium significance even though the impact will not be reversible and is of a permanent nature. Mitigation • Footprint size should be kept at a minimum so as to maintain as much natural vegetation cover as possible; • Only vegetation indigenous to the area should be considered for landscaping purposes; and • Wastewater limit values applicable to discharge of wastewater into watercourses as stipulated by the Department of Water Affairs should be strictly adhered to. 14.7 Cumulative impact of faunal habitat and displacement Source of the impact Destruction of faunal habitat and the displacement of species from their traditional home ranges during the operational phases of the proposed opencast and underground coal mine. Description of the impact Faunal species could be displaced during the operational phase. This could result in higher than normal social, grazing and browsing pressures on areas that would otherwise not have these impacts. This could result in degraded vegetation cover in areas that the life stock has moved to and a depauperation in the associated habitat i.e. from trampling, erosion, grazing or browsing and other forces. Significance The significance of the impact is expected to be of a medium significance without mitigation, this due to the displacement of faunal species from their habitats on site to allow for the mining of the proposed development. With mitigation the significance of the impact will be reduced to that of a low significance. Mitigation • Minimising the loss of flora and fauna in areas that are not directly affected by the new development; • Reduce the levels of disturbance on the area during mining; • All mining areas should be suitably top soiled and vegetated as soon as is possible after mining; and EIA-REP-325d-11 October 2012 160
