2. 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
3. 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
4. Typical Ausgrid network Projects
that are covered by an EIA
Distribution substations
Kiosks
Pole transformers (PT)
Distributors
Underground cables
Overhead power lines
5. 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

6. 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
7. 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

the EIA Document provisions to be reviewed

10. Ausgrid proposed Network project
located at Yerroulbin st Birchgrove
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
16. Amended EIA Document for Yerroulbin st
Birchgrove (Not all pages shown)
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
Please see the following 5
slides showing the plan

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

23. 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
24. 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.
25. 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
26. 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
