Our control techniques, processes and systems are world class

Our Intelligent Dust Management System (IDMS) utilises data from onsite weather stations, as well as forecast weather data from the Bureau of Meteorology, to continuously assess the potential for dust lift-off from the coal stockpiles. The IDMS automatically activates stockyard water sprays on a continual process to proactively manage optimal stockpile moisture levels. Water sprays are also utilised as required throughout all conveyor transfer operations, from train unloading through to shiploading.

A network of Real-Time Dust Monitors (RTDM) within the site boundary is used by our onsite personnel to respond to any potential elevated dust concentration measurements.

Port Waratah also routinely review the data collected by the Newcastle Local Air Quality Monitoring Network to understand Newcastle’s seasonal air quality performance. This information is shared throughout the business and is taken into consideration during operational planning.

Seasonal air quality monitoring reports for 2021, which are collated by the Department of Planning, Industry and Environment, showed that air quality results remained within national benchmarks and were recorded in the good to fair categories for the majority of the year. Port Waratah’s dust management performance was strong in 2021, recording no air quality related issues.

Case Study

Dust Monitoring now at rail loading facilities

The introduction of Real Time Dust Monitors (RTDMs) into the rail unloading facilities in 2021 has enhanced our Intelligent Dust Management System (IDMS), improving dust detection capabilities from the moment coal arrives. The baseline data captured over the year has improved our understanding of coal characteristics and the potential circumstances in which dust may be generated.

In the event that elevated dust concentrations are experienced, the IDMS is able to provide immediate notification to allow additional water sprays to be initiated to manage the coal transfer to the stockpile. Port Waratah aims to automate this process and fully incorporate the dust detection system in the dump stations into the IDMS in early 2022.
