Proposal details
This proposal seeks to amend the industrial sewage works Environmental Compliance Approval No. 8479-B3QHJZ, which currently regulates the sewage works for the collection, transmission, treatment, and disposal of a maximum daily flow of 2,100 cubic metres of mine water from the Sugar Zone Mine.
The amendment is for enabling year-round discharge of treated effluent into Gagegenha Lake, currently restricted to open water months and also includes the installation of a Rotating Biological Contactor (RBC) and associated sewage system at the proposed onsite workers' camp, accommodating up to 220 individuals.
The amendment also includes a waste rock dump primarily located within the North Tailings Management Facility (NTMF) catchment, with a 0.9 hectare section outside this area, which will be managed by a specially designed swale directing runoff back to the NTMF. A stormwater management plan has been developed to ensure runoff from the camp is managed within the sewage works.
