• A walled concrete platform, dedicated store with adequate flooring or bermed area should be used to accommodate chemicals such as fuel, oil, paint, herbicide and insecticides, as appropriate, in wellventilated areas. • Storage of potentially hazardous materials should be above any 100-year flood line, or as agreed with the Environmental Controlling Officer. These materials include fuel, oil, cement, bitumen etc. • Surface water draining off contaminated areas containing oil and petrol would need to be channelled towards a sump which will separate these chemicals and oils. • All materials prone to spillage are to be stored in appropriate structures with impermeable flooring. • Portable septic toilets are to be provided and maintained for construction crews. Maintenance must include their removal without sewage spillage. • Under no circumstances may ablutions occur outside of the provided facilities; • No uncontrolled discharges from the construction crew camps to any surface water resources shall be permitted. Any discharge points need to be approved by the relevant authority. • In the case of pollution of any surface or groundwater, the Regional Representative of the Department of Water Affairs must be informed immediately. • Store all litter carefully so it cannot be washed or blown into any of the water courses within the study area. • Provide bins for staff at appropriate locations, particularly where food is consumed; the construction site should be cleaned daily and litter removed. • Conduct ongoing staff awareness programs so as to reinforce the need to avoid littering.

Description of impact: Construction phase: It should be noted that the mine is located in an area classified as a high yield area that needs to be conserved. During the construction phase, the catchment yield (mean annual runoff) will be affected as construction activities within the footprint of the mining area could cause pollution. This water needs to be retained in a pollution control or storm water dam which will result in a decrease in storm water runoff. Operational phase: Opencast and proposed underground mining activities will increase the surface water pollution threat. Water found or contained within the open pit to be used for re-cycling and for coal washing purposes is characterised by elevated levels of nitrate, sodium, sulphate, hardness and conductivity. Exposure of “fresh” weathered overburden materials to natural elements such as water and oxygen might have the potential to accelerate the acidification of pyritic material by the generation of Acid Rock Drainage (ARD) leachate with the concomitant decrease in pH and mobilization of metals such as Fe, Al and Mn. Significance: The impact on surface water quality will be negative, possible of medium term duration low magnitude, may extent from the site and is of low significance overall. Mitigation will be required. Mitigation: • Prevention of overspill of mining activities, and associated activities into the surrounding streams and rivers. Implementation of the necessary monitoring and management programmes to ensure the integrity of all water resources in the area during the construction, and operational lifespan of the mine; • Containment of return waters in a clay lined return water dam; • Re-cycling of contaminated runoff waters from lined settling and evaporation dams; • Sealing of process waters circuit and containment structures; • Separate clean and dirty water systems; and • Provide sufficient storage capacity to contain contaminated waters i.e. adopt a zero discharge policy.
