We action proactive strategies to ensure effective noise management outcomes
Port Waratah incorporates noise controls into the design and operation of our plant and equipment, as well as the scheduling of work, the systems and procedures that direct our daily operations and long-term noise improvement strategies.
Ongoing compliance is demonstrated through our noise monitoring programme. Throughout 2020, we maintained full regulatory compliance with noise-related conditions specified in development consents.
Good progress was achieved with the Carrington Terminal’s multi-year Conveyor Drive Strategy, with upgrades to another set of primary and secondary stockyard conveyor drives in 2020.
Carrington Real-time Noise Monitoring Technology
Since the Real-time Noise Monitoring Trial commenced at Carrington Terminal in 2019, we have successfully demonstrated the ability to identify 10 separate noise sources using the technology.
We also identified that noise from our Carrington Terminal operations does not dominate the local noise profile, and therefore it has been an ongoing challenge to develop a reliable method of identifying onsite noise issues impacting adjacent residential areas. The trial identified that while background noise does increase and decrease in line with the Terminal’s operating status, the overall change in background noise is unlikely to be noticeable in residential areas in combination with other non-Port Waratah noise sources.
Throughout 2020, we focussed on trying to identify noises that may concern nearby neighbours, such as faulty idlers or alarms, as these noises typically have a higher pitch than normal operational noise. However, the practicality of this method proved to be challenging due to the variability in these types of noise. In 2021, we will review the trial outcomes, looking at how we can consolidate learnings and drive improvement.
