Understanding NSW Industrial Noise Management
The mining industry is a crucial driver of economic development, particularly within the rich mining heritage of New South Wales. Over the years, mining has been a key contributor to the state's economic wellbeing, providing around 40,000 jobs. At the core of this economic engine lie coal, gold, and copper, serving as the state's most valuable export commodities. By paying billions in mining royalties to the state government, mining companies in NSW contribute substantially to vital infrastructure and services, including roads, hospitals, schools, and law enforcement.
While the mining industry presents economic opportunities, it also faces significant challenges and responsibilities. In every jurisdiction, including New South Wales, stringent rules and regulations govern mining endeavours to ensure mining activities are conducted responsibly and sustainably. The NSW Environment Protection Authority (EPA) oversees these regulations, particularly focusing on noise management to protect both people and the environment from excessive industrial noise.
Those overseeing machinery noise at mine sites must understand these regulations to stay compliant and avoid potential penalties. This article will discuss these regulations and outline how Minetek can assist in achieving noise reduction to meet EPA standards.
The Role of NSW's EPA in Mining Operations
Before we move forward, let's take a moment to better understand the role of NSW's EPA. This governmental body is tasked with safeguarding the environment and public health across New South Wales. Its responsibilities include regulating various activities that could impact the environment, such as air and water pollution, waste management, and land use. It is also responsible for overseeing industrial noise.
Under Schedule 1 of the Protection of the Environment Operations Act 1997 (POEO Act), the EPA regulates noise from licensed industrial premises, including mines. If noise levels exceed the set limits due to the occupier's failure to maintain or operate the plant properly or handle materials efficiently, the EPA can issue noise control notices, prevention notices, and noise abatement directions to address the issue.
The penalties for non-compliance can be significant:
Under the POEO (Noise Control) Regulation, the EPA also oversees the specifications for noise labels to ensure compliance with standards.
This underscores the necessity for mines in NSW to strictly adhere to environmental standards to evade regulatory penalties and, crucially, uphold their social license to operate. Compliance with EPA regulations not only mitigates legal risks but also promotes sustainable practices that safeguard the well-being of workers and nearby communities while preserving natural habitats.

Mines operating across the region must take proactive measures, such as noise reduction technologies provided by companies like Minetek, to uphold environmental standards and secure the sustainable future of mining operations in New South Wales.
Minetek's Solutions for Noise Reduction
Mining operations often involve a range of machinery, each contributing to a significant accumulated noise level. For instance, core extraction tools such as drills or Stageloaders typically operate within the range of 90 – 110dB, while haulage trucks emit noise levels around 90-100 dB. Minetek steps in as a crucial partner for mining sites in New South Wales, facilitating the achievement of reduced noise levels to align with EPA standards, all without compromising operational efficiency or profitability.
Minetek specialises in creating the world's quietest mining machines, capable of reducing noise levels by up to 50%. This reduction not only mitigates potential harm caused by excessive noise but also ensures compliance with regulatory and community noise expectations. Our solutions are highly adaptable, allowing for noise attenuation in mining machinery while preserving essential aspects like machine integrity, airflow, and maintenance access. Backed by extensive experience in sound auditing and testing, coupled with our consultative approach, we instill confidence in mining operations that their machinery will meet both regulatory and community noise standards, securing support from key stakeholders for future expansions.
Our proven track record speaks for itself. Minetek has developed sound packages for over 90 different OEM models, and over 1,800 mining machines are already equipped with Minetek sound packages. These include renowned brands such as Liebherr, Komatsu, Caterpillar, Hitachi, Terex, Sandvik, LeTourneau, Epiroc, and NHL.
What's more, we offer a comprehensive suite of noise testing services, encompassing compliance testing compliant with ISO 6393/6395 standards, sound intensity testing, mobile fleet screening, and evaluation of operator noise exposure. Working closely with our clients, we create practical mitigation solutions that match the specific needs of each mining company, ensuring compliance with safety, regulatory, and community expectations.
As part of our sound attenuation, Minetek manufactures industrial exhausts for mining machinery and leading OEMs. These exhausts are engineered with sound reduction properties tailored to each machine's acoustic frequency. Our exhausts leverage technology and simulation programs to target specific frequencies while offering substantial heat reduction capabilities.
Final Thoughts
With Minetek's Sound Attenuation and Noise Reduction solutions, mining companies across New South Wales can ensure compliance with stringent EPA regulations and mitigate the risk of regulatory penalties. Those responsible for managing mining machinery can rest assured, knowing they are safeguarding nearby communities, and the environment.
