The M5 East Motorway includes a 4 km long tunnel
that is ventilated through a single exhaust stack system.
The exhaust stack is located in Turrella and is designed
to remove all motor vehicle exhaust emissions from
the tunnel. In the first half of 2002, immediately after
the opening of the tunnel, NSW Health received over
80 complaints from local residents who believed their
health was being affected by the stack exhaust.
Monitoring in the local area showed that pollutant
levels had not changed, so there was no apparent
cause for the symptoms.
After consultation with key
stakeholders and experts, NSW Health developed
a multi phase investigation strategy to examine the
health concerns and symptoms of the local residents.
This report is of Phase 1 of that strategy
