Air Quality

Monitoring of air quality at Cadia Valley Operations (Cadia) is managed in accordance with the Cadia Air Quality Monitoring Program (Cadia AQMP) which was approved by NSW Department of Planning and Environment in July 2014.

Air Quality monitoring is conducted using Tapered Element Oscillating Microbalance (TEOM) monitors and Dust Deposition Gauges.

Monitoring undertaken includes:

  • PM10 Ambient Dust Monitoring
  • Deposited Dust Monitoring
  • Visual Dust Monitoring
  • Meteorological Monitoring

PM10

PM10 is monitored using Tapered Element Oscillating Microbalance (TEOM) monitors, which measure average PM10 concentration every 15 minutes, continuously

Deposited Dust

Dust deposition monitoring is conducted using dust deposition gauges (DG). The gauges are collected once per month.

Visual Assessment

Visual dust is monitored during routine inspections and when complaints are received. Where excessive dust generation has been identified, mitigation measures will be implimented.

The following table shows the parameters for monitoring in the Cadia Air Quality Monitoring Program:
