Description of impact Fauna and flora within the area may be disturbed by the mining activities on the site and on the property as a whole e.g. firewood collection, flower picking interfering with wildlife etc. This, if not controlled properly can lead to an impoverished ecosystem and reduction in biodiversity. Significance: The impact is considered to have a medium significance based on the impact identification matrix. The key impact is that human encroachment during the operational phase could disturb the occurrence of flora and fauna on the site. Mitigation measures have been set out in the Environmental Management Plan (See Annexure 5: Environmental Management Programme (EMPr)). The impacts will become more pronounced if the suggested mitigation measures are not implemented. Mitigation: • Minimising the loss of indigenous flora and fauna in areas that are not directly affected by the new development; • Reduce the levels of disturbance on the area during construction; 137
• All construction areas should be suitably top soiled and vegetated as soon as is possible after mining; • Disturbed surfaces to be rehabilitated must be ripped, and the area must be backfilled with topsoil or overburden. • 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 rehabilitation purposes; and • Wastewater limit values applicable to discharge of wastewater into watercourses as stipulated by the Department of Water Affairs and Forestry should be strictly adhered to. 13.4 Noise 13.4.1 Increased Noise and vibration Table 31: Assessment of the possible impacts on Noise and Vibration during the construction and operational phase Activity Noise generation on site during the construction and operational phase Nature of the impact Receiving environment Magnitude Weighting factor (WF) Mitigation Efficiency (ME) Significance Significance With Mitigation (WM) EIA-REP-325d-11 October 2012 Blasting and construction activities which generate noise that exceeds the current ambient noise levels experienced over the site and surrounding areas Machine operators and workers, surrounding communities 138 Status - Extent (footprint; site; regional; national; international) REGIONAL Intensity (low; medium; high) LOW Duration (short; short-med; medium; long; permanent) LONG-TERM Probability (Improbable; possible; likely; highly likely; definite) HIGHLY LIKELY WF (low; low-medium; medium; medium-high; high) LOW MEDIUM ME (high; medium-high; medium; low-medium; low) MEDIUM HIGH Without mitigation (WOM) With mitigation (WM) LOW (Extent + Intensity + Duration + Probability) x Weighting Factor (3 + 1+ 4+ 4) x 2 = 24 Low to Medium WOM x ME = WM 24 x 0.4 = 9.6 Low Source of the impact: Possible sources of disturbing noise of the Vunene Colliery (Pty) Ltd are listed in table 30. Of these sources, those with the greatest potential to be disturbing are: • Increase noise levels from vehicular traffic and other equipment associated with the construction of the proposed mine; and • Vibrations and noise associated with blasting.
