Purpose of Noise Assessment

To protect the health and wellbeing of residents and local communities, and minimise effects on noise, having regard to relevant limits, targets or standards

[EES Scoping requirements – Amenity and Environmental Quality]

Methodology underpinning Noise Assessment

Baseline

  • Measurements: Existing Ambient and Traffic noise

Criteria

  • NIRV (Noise from Industry in Regional Victoria)
  • Other guidelines (VIC EPA, NSW EPA)

Assess

  • Model Scenarios
  • Comparison of predicted noise level with criteria

Mitigate

  • Consultation with industry experts
  • Mitigation targeted to reduce highest noise levels

Predicted noise levels comply with evening period NIRV limit for day/evening activities at all locations, for all scenarios Predicted noise levels comply with night period NIRV limit for night activities at most locations, for most scenarios (two exceptions of 1dB exceedance)

Mitigate - Proposed mitigation measures

Proposed that some items will not

  • perate at night in Year 1 without

prior confirmation from measurements that they can achieve the night criteria Examples:

  • Haul trucks (overburden)
  • Overburden support dozer
  • FEL at overburden
  • Water truck at overburden
  • Amphirolls

Plant-based mitigation packages - examples

Noise Monitoring and Management Plan

Development of noise management plan

  • Framework for managing

noise within the community

  • Noise compliance

monitoring

  • Validation of equipment

emissions

  • Reporting and verification
