Mount Isa has one of the largest, most intensive air quality monitoring networks of any city in Australia. Our Air Quality Control (AQC) operators use data captured at monitoring points located across our community to monitor emissions and observe emerging weather patterns.

Our extensive monitoring network is regularly reviewed to ensure we are capturing the most comprehensive and accurate data for air quality management in the community.

In 2014, we finalised an expansion of Mount Isa's air quality monitoring network.

The expanded network is helping us to better pinpoint the source of emissions and understand the factors causing them to impact on particular areas of our community at any given time. Having access to this specific data assists us to fine-tune our controls and introduce more efficient air quality management techniques.

​Inside Air Quality Control (AQC)

The calculations, monitoring requirements and limits for effectively managing sulphur dioxide emissions are technically complex, and take into consideration a number of variable factors. These include understanding and predicting the interaction of emissions with various atmospheric, weather and ground conditions, which can change rapidly.

Our AQC operators provide daily forecast and planning advice to our smelter operations, and use real-time air quality data to monitor emissions, working both proactively and reactively to minimise the impact of sulphur dioxide in our community and ensure compliance with our regulatory limits.

Depending on the outcomes of their investigations, the AQC may escalate action following the alert process.
