Digital Train Radio System Como Site Review of Environmental ...

Given the site characteristics and the scope and size of the proposed work, t is anticipated that
erosion and sediment risks are minimal and can be effectively managed through the
implementation of standard measures outlined in the Landcom/Department of Housing
Managing Urban Stormwater, Soils and Construction Guidelines (the Blue Book) (Landcom
2004).
No operational impacts are expected.
Possible Control Measures
A site specific erosion and sediment control plan will be prepared as part of CEMP. This plan
will detail appropriate erosion and sedimentation control measures which will be implemented
during the construction phase. The measures will include, but not be limited to those outlined
below.
• All spoil not being used for backfilling will be transferred directly to skip bins or stockpiled
appropriately.
• Appropriate stockpiling of materials will take place away from drainage lines, waterways
and drains.
• Any soil that may be contaminated or weed infested will be stockpiled separately before
being removed from the site.
• Sediment fences and bunds will be installed and inspected regularly.
• The tracking of soils on public roads will be prevented by using appropriate shaker
grids/wheel wash facilities.
• Soil will be removed from public roads and other paved areas using dry street sweepers or
other measures.
• Disturbed areas will be replanted, if required.
During maintenance activities, any spills will be attended to and treated in an appropriate and
timely fashion in accordance with normal RailCorp management procedures.
4.2 Water Quality and Hydrology
Existing Situation
The nearest water body is the Georges River, approximately 40 metres away, which forms part
of the Georges River catchment. The suburban stormwater system is along the main roads (i.e.
Cremona Road) and some stormwater drains may be present around the construction footprint.
The groundwater depth and quality are not known
In addition to sediment-rich runoff, construction activities can generate contaminated water,
such as:
• liquid waste from non-destructive excavation;
• water from spills, and from washing equipment and tools;
