How we monitor air quality
Twelve real time monitors are positioned around RG Tanna Coal Terminal (RGTCT), Barney Point Coal Terminal (BPCT) and in community locations to provide GPC with data every two minutes, allowing us to assess and control dust generation impacts on the community and to ensure compliance with our licence conditions.
The monitors are designed to provide accurate and immediate data on particulate concentrations, wind speeds and directions to pinpoint the location of emission sources, allowing the activation of sprinkler systems to prevent potentially high dust emissions.
We also maintain a network of dust depositional gauges (DDGs) in and around our operations and the community. The gauges measure the quantity of coal dust, mineral dust and plant or insect material settling in the area and are a good indication of the success of our coal terminal’s in reducing our coal dust emissions.
We have 25 DDGs located in and around our main operational sites at RGTCT, Port Central including BPCT, the Gladstone Marina and in 12 community locations.
Real time air quality data
We use various dust suppression measures to minimise dust emissions from our operations, including:
- water sprays on coal conveyors and stockpiles
- wind breaks established using direct seeding techniques
- watering or applying dust suppressant to unsealed roads used by GPC vehicles
- watering or applying dust suppressant to truck loads
- covering loads prior to travelling on public roads
- installation of dust extraction equipment on conveyors and shiploaders
