How is air quality inside the tunnel monitored?
Tunnel and ventilation stack emission air quality must meet strict standards set by the NSW Government.
We continuously monitor the air quality within our tunnels and ventilation stacks. A system of jet fans, axial fans, ventilation tunnels and exhaust points manage air within the tunnel.
This and other information relevant to environmental management is set out in the relevant asset Operational Environmental Management Plan (OEMP). Contact us to request a copy of the OEMP.
