The Compliance Operations Unit undertakes compliance audits of mining operations and exploration activities to assess whether titleholders are meeting their compliance requirements under the Mining Act 1992. Where non-compliances are identified, further enforcement action may be taken, in accordance with the Regulator's compliance and enforcement framework.

Audit reports may also identify opportunities for improvement to strengthen the compliance management activities of the titleholder.

The NSW Resources Regulator undertakes a compliance audit program to assess the level of operator compliance with Regulations. View the compliance audit program report:

Mining sites within special catchment areas

Audit report [PDF, 1489.46 KB]

During April and May 2017, three separate incidents of oil spill from transformers occurred at isolated and disused mine ventilation shaft sites within the Sydney drinking water catchment Special Areas. Each of these incidents resulted in a moderate or minor spill of oil on mining land which was reported to WaterNSW and EPA. Monitoring and water sampling, overseen by WaterNSW, was undertaken to ensure Sydney’s drinking water supply was not affected with this monitoring showing the incidents posed minimal risk to water supplies following containment and remedial actions.
