NSW EPA Fines Perilya $30,000 Over Dust Management Failures

NSW EPA fines Perilya $30,000 for dust management failures at Broken Hill mine

NSW EPA Dust Enforcement at Broken Hill Mine

On 27 March 2026, the NSW Environment Protection Authority (EPA) issued a $30,000 penalty notice to Perilya Broken Hill Ltd following a routine inspection at its Southern Operations mine along Broken Hill’s Line of Lode. EPA officers observed visible dust pollution across multiple areas of the facility, with no dust suppression measures operating at the time despite prevailing dry and windy conditions. The penalty was issued under the Protection of the Environment Operations Act 1997 (POEO Act) for failure to comply with the environmental protection conditions attached to the site’s Environmental Protection Licence (EPL).

This enforcement action carries weight beyond its immediate financial penalty. Broken Hill’s Line of Lode is one of the world’s largest and richest lead and zinc ore bodies, with silver as a significant by-product. The naturally elevated concentrations of lead in the local soils and ore bodies mean that airborne dust at this site is not a routine nuisance issue. It is a direct vector for toxicological exposure to the surrounding community. NSW EPA Director Operations Scott Kidd made this point explicitly, stating: “Dust generated by metalliferous mining, including iron, copper, gold, silver and zinc, can pose risks to air quality, human health and the environment. Given the surrounding environment and the mine’s proximity to the community, dust management should be a top priority.”

For environmental professionals working in site contamination, mine rehabilitation, remediation contracting, and environmental management, this enforcement action is a clear signal that written compliance plans are not sufficient. Regulators are actively verifying whether physical controls are actually operating in real-world meteorological conditions, not simply whether they are documented in an approved plan. This distinction has significant practical implications for how environmental management plans are structured, audited, and enforced across the sector.

Key details of the enforcement action and site context

The $30,000 penalty was applied under the POEO Act following direct observation by EPA officers during a routine, unannounced site inspection. The inspection found that dust suppression equipment, including water carts and sprinklers, was not in operation across multiple areas of the Southern Operations facility, notwithstanding conditions that clearly warranted active controls. The absence of any operating suppression measures during dry and windy weather was the central basis for the penalty. This is not an allegation based on modelled exceedances or monitoring data alone. Regulators witnessed visible dust pollution directly, which places the evidential burden very clearly on the operator.

Perilya’s Southern Operations mine extracts lead, zinc, and copper mineralisation from the Line of Lode deposit. The geological character of this ore body means that dust generated during mining, haulage, and processing activities carries a heavy metals load that is materially different in toxicological significance to dust at a construction or civil works site. The EPL issued to Perilya included an Environmental Improvement Program that was incorporated into the licence in May 2020. This program covered air quality controls, noise impacts, and surface water management, among other operational areas. Perilya completed all required actions under this program by May 2022. The May 2026 penalty therefore relates to operational practices occurring after the formal improvement program had been discharged, which highlights that completing a mandated program does not provide ongoing protection from enforcement if day-to-day operational controls lapse.

The practical distinction the EPA is drawing here is between documented compliance and demonstrated compliance. An EPL condition requiring dust suppression is not satisfied by having water carts on-site. It is satisfied by those carts being deployed and operating when conditions demand it. This is an operationally demanding standard, particularly for large metalliferous mining operations where multiple concurrent work areas require simultaneous management. For a site like Southern Operations, which is located in proximity to residential areas of Broken Hill, the community exposure risk amplifies the regulatory focus. Lead in particular has well-established toxicological effects at low blood lead levels, especially in children, and there is no safe threshold for lead exposure under current scientific understanding. This is why the EPA’s approach to dust at Broken Hill is more aggressive than it might be at a comparable site in a remote or industrial setting.

It is also worth noting that the penalty amount, $30,000, sits within the range available to the EPA for notices issued without court proceedings under the POEO Act. More serious or repeated contraventions can attract substantially higher penalties through the Land and Environment Court, where maximum penalties for corporations can reach into the millions of dollars per offence. The $30,000 figure should not be read as the ceiling of the EPA’s enforcement toolkit, but rather as a first-response regulatory instrument used in this instance. Continued non-compliance would be likely to attract escalating action.

Australian context: regulatory frameworks governing dust at metalliferous mine sites

The regulatory framework governing dust management at metalliferous mine sites in New South Wales draws on several overlapping instruments. The primary statutory obligation is the general duty under the POEO Act to prevent pollution of the environment. Specific operational requirements are then set out in an EPL, which is tailored to the individual site’s risks, commodities, location, and operating conditions.

NSW EPA Fines Perilya $30,000 Over Dust Management Failures at Broken Hill Metalliferous Mine

On 27 March 2026, the NSW Environment Protection Authority (EPA) issued a $30,000 fine to Perilya Broken Hill Ltd for failing to adequately manage dust pollution at its Southern Operations lead, zinc, and copper mine. During a routine site inspection along Broken Hill’s 'Line of Lode', EPA officers observed visible dust pollution across multiple areas of the facility. Notably, no dust suppression measures (such as water carts or sprinklers) were operating at the time, despite the prevailing dry and windy conditions.

The environmental improvement program incorporated into the EPL in May 2020 covered air quality controls, noise impacts, surface-water management, and more — not only air quality and surface-water controls. All required actions under this program were completed by Perilya in May 2022.

Why it matters for environmental professionals and their clients

For site contamination practitioners, environmental managers, and remediation contractors, this penalty serves as a critical reminder of the regulatory focus on airborne contaminant pathways:
