The EPA is responsible for actively regulating a diverse range of processing and manufacturing chemical industries, metallurgical industries, and environmentally relevant heavy industries Statewide.
These industries include large smelters (ferro alloy, aluminium and zinc), cement and lime kilns, superphosphate fertiliser manufacture, foundries, premix bitumen plants, alkaloid and pyrethrum extraction and processing, bearing manufacturing, waste oil treatment/refining and specialist chemical works.
In view of the diverse nature of these industries, there are a broad range of environmental issues that may be associated with some activities, including:
- site contamination (largely historical)
- groundwater contamination and treatment where necessary
- industrial wastewater treatment and disposal
- discharge water quality
- atmospheric emission quality
- noise, dust and odour emission management
- waste management and recycling
- industrial landfill management
The EPA sets environmental conditions through Permits and EPNs to manage the environmental aspects of each activity.
