Digital Train Radio System Kingsgrove BTS Site Review of ...

Potential Impacts
It is highly unlikely that the site can be contaminated by known activities or by contaminants
migrating from the known contaminated site.
However, the limited investigation cannot exclude potential contamination as the result of
unknown past activities, either on the site or in the vicinity. There is a risk that contaminants
could be encountered during the proposed work. If encountered, contaminants may pose a risk
to the health of workers and the environment in general.
Control Measures
The risk of encountering unknown contaminants during excavation will be managed in
accordance with RailCorp procedures, the Environmental Management Plan for DTRS project
and land contamination legislation.
The impact of potential contaminants will be minimised through a range of control measures
including, but not limited to, those outlined below.
During excavation, site workers will look for signs of potential contamination such as the
presence of waste and/or other imported materials, odours, soil colouring, floating layers in
groundwater etc.
If any contamination is encountered or suspected, work will stop immediately and the site
will be fenced off.
Any potential contamination will be investigated and work resumed only after approval from
the Health, Safety & Environment (HSE) Manager is obtained.
The site will be validated before work begins.
Contaminated soil will be segregated in a special container before classification and
disposal.
The CEMP will further detail the proposed control measures.
