GPC is committed to the ongoing control and improvement of air quality associated with port activities. Data collected from sites around Gladstone allows us to assess and actively control dust impacts. We monitor particulate concentrations, wind speed, wind direction, temperature and relative humidity.
How we monitor air quality
Three compliance and nine operational real time monitors are positioned around RG Tanna Coal Terminal (RGTCT), Barney Point Terminal (BPT) and in various community locations.
The monitors are designed to provide accurate real-time data on particulate concentrations, wind speed and direction at each location.
We also maintain a network of dust deposition gauges (DDGs) that measure the quantity of coal dust, mineral dust, plant and insect material settling in an area and are a good indication of the effectiveness of our coal dust emission management measures.
Dust mitigation
GPC uses various dust suppression measures to minimise dust emissions from our operations, including:
- water cannons and misting sprays on coal conveyors and stockpiles
- wind breaks established using direct seeding techniques or planting
- watering on unsealed and sealed roads used by GPC vehicles
- covering loads prior to travelling on public roads.
