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 />
