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