Context: Environmental Noise Assessment Near Cobar Mine Operations

A recent mining noise monitoring project was completed near Cobar, NSW, targeting rural properties located adjacent to an active mine. The objective was to conduct an environmental noise assessment aligned with NSW EPA requirements, capturing real-world sound levels near operational haul routes and infrastructure.

The surrounding region combines remote bushland with sparse rural development, making rural noise receivers especially sensitive to industrial activity. The monitoring was conducted to support compliance with the Protection of the Environment Operations Act 1997 and project-specific consent conditions.


Field Note: Flooding Impact on Site Access

During the mobilisation phase, temporary flooding caused access delays to the monitoring site. The image below shows floodwaters encroaching across the road shoulder, requiring rerouting and postponement of the equipment setup by several hours.

Despite the interruption, the team completed setup and initiated unattended noise logging without compromising the integrity of the assessment. Monitoring was adjusted to align with operational hours and meteorological conditions once access was restored.


Methodology: Cobar NSW Noise Monitoring Approach

The mining noise monitoring setup was designed to capture worst-case conditions:

✅ Type 1 precision sound level meter installed near key rural noise receivers
✅ Weather-protected microphone mounted on tripod
✅ 24-hour unattended noise logging with timestamped data
✅ Wind speed, temperature and direction logged concurrently
✅ Photo documentation and GPS reference of the monitoring location

This methodology ensured the environmental noise assessment met EPA and site-specific regulatory expectations.


Compliance Objectives

✅ Verify that mining activity in Cobar NSW did not exceed regulated acoustic limits
✅ Identify potential areas for mitigation or future management
✅ Support transparency in compliance reporting for mining approvals
✅ Establish a record of unattended noise logging under realistic environmental conditions

Regional Insight – Mining in Cobar NSW

Cobar NSW is a well-known resource district where extractive industry operations often run near sensitive land uses. Acoustic impacts can become more pronounced due to open terrain and low background noise. Accurate mining noise monitoring and environmental noise assessments are essential to maintain compliance, especially for rural noise receivers located along haul corridors or close to infrastructure.
