KCM pollutionThe Zambia Environmental Management Agency has issued compliance orders to eight mining firms on the Copperbelt.

Mopani Copper Mines was ordered to comply with the limits for effluent discharged through the main mine drain into Mufulira Stream and through the Frikkers’ Lake Outlet into Chibuluma Stream, and to install monitoring equipment for all parameters.

Konkola Copper Mines must ensure that all limits for effluents and emissions are adhered to, especially for sulphur dioxide and cadmium, which were found to be 10.3 and 13.4 times above statutory limits, respectively. In addition, the mine was directed to stop discharging pregnant liquor solution into the pollution control dam, to install online monitoring equipment, to restore flow channels and continuously de-silt in Chingola, Mushishima and Mutimpa Streams, to conduct an environmental impact assessment of Chingola and Mushishima Streams as well as Hippo Pool, to investigate why the groundwater is non-compliant for parameters such as pH, manganese and total suspended solids, to develop a programme to clean up the groundwater, to complete a water recycling project at Mutimpa Tailings Dam, and to stop discharging effluent from Mutimpa Tailings Dam containing parameters above the legal limits – all with varying deadlines between now and May 2017 (more details are known about the compliance order for Konkola due to leaked documents from the mining firm’s legal department).

Chambishi Copper Mine in Kalulushi was ordered to keep the levels of cobalt and total suspended solids discharged from the new dam into Chambishi Stream within limits, and to install online effluent monitoring equipment on the main mine drain to Tailings Dam 6, before the effluent gets mixed with that from other facilities.

Chambishi Metals must submit returns, and install online monitoring equipment on the effluent drain to Tailings Dam 6, before the effluent gets mixed with that from other facilities.

Chambishi Copper Smelter in Kalulushi was directed to install online effluent monitoring equipment on the smelter and acid plant drains.

Sino-Metals Leach in Kalulushi must construct proper settling ponds for effluents, and install online monitoring equipment.

Bolo Mining in Kalulushi must ensure that all effluents are compliant with limits. Bolo was also ordered to install online monitoring equipment, and to drill boreholes around the tailings dam to allow for monitoring of groundwater.

Hui Fan Company in Kalulushi was ordered to immediately stop its concentrator and illegal discharge of tailings in the decommissioned Tailings Dam 1, to clean up the Bwafwano Stream, and to redesign its tailings storage facility, complete with an undated environmental impact assessment.
