Environmental Impact Assessment
Awareness TrainingBy
David King
Why do we need an EIA in Ausgrid
Due to the Environmental Planning legislation (Environmental Planning and Assessment Act 1979)
All new work requires an assessment
To ensure that the environment is considered
As an environmental planning instrument / tool
To consider ecologically Sustainable Development
Why do we need an EIA in Ausgrid network construction & maintenance
Consequences of breaching the legislation
Severe penalties For corporations , Directors, Managers and individuals
Fines up to 1.1m – EP& A NSW planning $5m – POEO – NSW Pollution $5.5m – EPBC – Federal environmental Up to 7 years Jail Remediation and other additional costs
Typical Ausgrid network Projects that are covered by an EIA
Distribution substations Kiosks Pole transformers (PT)
Distributors Underground cables Overhead power lines
Typical Activities covered in an Ausgrid EIA
Construction Excavation Traffic disruptions After hours works Vegetation clearing Using heavy machinery Storing materials &
equipment Staging areas Discharging water
Operation Construction Noise Handling oil Oil filled equipment EMF
Maintenance Traffic disruptions Excavation Vehicle access
Things to be aware of about Ausgrid EIA document
EIA is a legal Document EIA will be used in court as evidence for and
against you EIA Is a document to be taken seriously by both
parties and will form part of the contract with the Construction Company
The Ausgrid EIA Worksheet is divided basically into four tables following
Table 1 – project details including a description of the environment where the works will take place
Table 2 – possible approval and licences which may be required
Table 3 - sensitive areas and issues that be affected by the project. etc. sulphate soils
Table 4 – Project specific environmental controls that are required in addition to the controls already listed in Environmental handbook
Typical Ausgrid network project that required the EIA Document provisions to be reviewed

The following EIA did not address the issue of the close proximately of the harbour foreshore and the associated risk in polluting this prestige area. This issue was raised at the pre-works and the EIA was amended

New EIA addresses the issue of the waterways and has requested that an Erosion and sedimentation plan to be produced and approved by Environmental services group

Another project that the EIA Document needed to be revised due do to the changes in the scope of works

Ewos St Cronulla CCO016191
The proposed Low Voltage jointbay original position was to be excavated adjacent the pole. Unfortunately due to the location of the existing cable this would have raised the issue of maintaining pedestrian access and also the bending radius / length of the existing cable in the jointbay
With consultation with the field service representative it was proposed the jointbay be moved into the park area to follow the existing cable
Ewos St Cronulla CCO016191
Unfortunately the EIA only covered the excavation works in the carriageway & footway area.
The EIA did not address the issue of the close proximately of the waterway and the associated risk in polluting this prestige area.
Ewos St Cronulla CCO016191
The issue was raised with the field service representative and work in the park was put on hold until the matter was resolved.
Outcome was to minimise the impact of the works . Additional sediment measure was initiated in the park area and the jointbay was only excavated on the morning of the commissioning of the new cable . Backfilled same day
Summary EIA documents are legal
documents EIA document are to minimise
the risks to Ausgrid & the environment
If the EIA document supplied with the Ausgrid works order does not cover or seems not to cover the proposed work please refer the matter to your Ausgrid representative assigned to that project
Be aware of your Ausgrid responsibilities -see environmental code of conduct
Not banana bread was harmed in the produce of this presentation
