Air quality
Protecting air quality is essential to our operations and we are committed to minimising emissions and dust to safeguard the environment and nearby communities.
Our commitment
We are committed to minimising adverse air quality impacts associated with our operations and where possible protect the environment through the efficient use of natural resources.
Our approach
Our business undertakes operational activities which generate dust and other air emissions. These activities include drill and blast, load and haul, and ore processing.
We manage dust in line with Environmental Protection Act 1986 (WA) and relevant licence conditions. We take practical steps to control air emissions, aiming to prevent fugitive dust and reduce its impact on vegetation, soil and local amenities. Measures include the use of water carts and dust suppressants on high traffic areas, physical barriers and sprinklers at material transfer points on our processing infrastructure and loading facilities, and a sealed private haul road at our Onslow Iron operations to reduce wheel-generated dust from our haulage fleet.
Under the National Environment Protection (National Pollutant Inventory) Measure 1998, facilities generating emissions of any of the 93 substances regulated under the scheme are required to report volumes to state and territory environment protection agencies. MinRes reports listed emissions annually to the National Pollutant Inventory (NPI) for facilities exceeding reporting thresholds.
Key documents
To support our commitment, we have established a robust framework of policies, standards and procedures:
