IMPACT
ENVIRONMENTAL SAFEGUARDS
Consultation is to be carried out with all affected property owners and businesses during
detailed design and construction to develop and implement measures to mitigate
impacts on land use viability, infrastructure and severance. Consultation with local
businesses would identify appropriate management strategies to avoid or minimise
impacts on access and operations. This would include consideration of measures such
as additional signage and alternative access arrangements.
Disruptions to property access and consultation cohesion and traffic would be notified
to team landowners at least five days in advance in accordance with the relevant
community consultation processes outlined in the Traffic Management Plan.
Land use
Prior to the commencement of utility work, consultation is to occur with identified
persons and organisations that may be adversely affected by service disruptions (such
as businesses, educational and/or police facilities) to determine any special
requirements or alternative service arrangements.
Soils and geology
A Soil Management Plan is to be prepared in accordance with QA Specification G38 and
implemented as part of the CEMP. The SMP is to identify all reasonably foreseeable risks
relating to subsurface impacts and pollution associated with undertaking the activity
and describe how these risks would be managed and minimised during construction.
That would include arrangements for managing pollution risks associated with spillage
or soil contamination on the site and adjoining areas and monitoring during and postconstruction.
In addition to the implementation of general erosion, sediment and water quality control
safeguards, any sediment, washdowns, and refuelling.
Where groundwater is intercepted during construction works, it is to be managed to
minimise potential adverse impacts in accordance with the RTA Technical Guideline:
Environmental management of construction site dewatering. These may include, but
not necessarily be limited to:
- Options to collect and store groundwater to enable recharge of the water table (such
as via grassed swales);
- Where recharge is not appropriate or feasible, discharging groundwater to the surface
water drainage system following; and
- Appropriate treatment to ensure discharged water is of sufficient quality.
Prior to any dewatering activities being carried out, an approval must first be obtained
in accordance with Section 92 of the WM Act.
The rehabilitation of disturbed areas is to be carried out progressively and in accordance
with:
- Managing Urban Stormwater: Soils and Construction series;
- RTA Landscape Guideline; and
- Roads and Maritime Guideline for Batter Stabilisation Using Vegetation.
Contamination
A Contaminated Land Management Plan (CLMP) is to be prepared and implemented for
any areas of land likely to be contaminated. The CLMP is to be prepared in accordance
with relevant requirements of the Roads and Maritime Guideline for the Management of
Contamination.
If contaminated areas are encountered during construction, appropriate control
measures are to be implemented to manage the immediate risks of contamination, such
as the diversion of surface runoff, capture of any contaminated runoff or temporary
capping. All other work that may impact on the contaminated area are to cease until
the nature of the contamination has been confirmed and any necessary site-specific
controls or further actions identified in consultation with the Environment Manager and
/ or EPA.
A site-specific emergency spill plan is to be developed and include spill management
measures in accordance with the Roads and Maritime Code of Practice for Water
Management and relevant EPA guidelines. The plan would address measures to be
