The document provides a detailed risk assessment and mitigation matrix for various mining-related activities, including water abstraction, infrastructure construction (roads, pipelines, and slabs), and underground mining. It focuses on the impacts on wetland systems (specifically S1, S2, S4, S7, S8, S9, S10, S12, S13, and S14) and groundwater, outlining measures such as the use of Class C liners, groundwater monitoring, and rehabilitation plans to prevent habitat transformation and pollution.

• Water abstraction from supply wells (CBH2D and CBH3S) is expected to cause groundwater drawdown and the formation of a dewatering cone, which may reduce the recharge of wetland resources and affect communities reliant on surface and groundwater.
• Underground mining activities and voids pose a risk to multiple wetland systems (1, 2, 3, and 4) and seep wetlands (S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S12, S13, and S14) through groundwater drawdown, requiring monitoring of inflows and the use of grouting to manage excessive inflows.
• The construction and operation of surface infrastructure—including the main workshop platform, RoM stockpile slabs, and office blocks—can lead to the degradation of grasslands, wetlands, and riverine habitats through site clearing, soil disturbance, and increased runoff.
• To prevent subsurface water pollution from the pollution control dam (PCD) and associated tanks, the document mandates the installation and maintenance of Class C liner systems.
• The construction of access roads for heavy and light vehicles through seep wetland S2 is mitigated by installing connecting pipes to maintain hydrological connectivity between wetland areas on opposite sides of the road.
• Post-mining mitigation for infrastructure and mining voids includes the treatment and release of decant water, the removal of contaminated materials to certified disposal sites, and the implementation of a wetland rehabilitation plan (Appendix U).
• The Bio-Mite Sewerage treatment plant and associated storage are identified as risks for potential spillage, with a requirement to remove humus to a licensed site in Piet Retief.
