MOD 6 - transfer floor area to child care centre use (Lot 2)

I've had a look at the documentation, there are no State Heritage
concerns regarding the proposed modifications that require a formal
response from the Heritage Division.

DPE does not need to refer this project, including any future
modifications, to the Heritage Council (i.e Heritage Division of OEH),
however other Divisions of OEH may respond separately in relation to
Aboriginal Cultural Heritage.

Kind regards

Dear Sir or Madam

I refer to the Department's letter of 24 January 2019 regarding
Notification of Modification Request for the Eastern Creek Business
Hub Concept Plan, (SSD 5175 MOD 6) at Rooty Hill Road South, Eastern
Creek for `Modification to the concept approval (SSD 5175) to transfer
500m2 of gross floor area (GFA) from large format retail to the child
care centre, resulting in a child care centre with a total GFA of
1,200m2 and re-located to the south western corner of Lot 2'.
Submissions need to be made to the Department by 8 February 2019.

Please find attached a copy of Endeavour Energy's previous submission
made to the Department on 26 November 2018regarding:

* SSD 5175 MOD 4: Modification to the concept approval to amend the
stormwater drainage system, construct a new roundabout on the internal
access road between Lots 1 and 2, with associated realignment of the
lot boundaries.
* SSD 8588 MOD 2: Modify the development consent to amend the layout
of the Lot 2 car park and building envelope, to reflect the above
concept plan modification.

The recommendations and comments made therein are also valid for this
Modification Request.

As shown in the below site plan from Endeavour Energy's G/Net master
facility model (and extract from Google Maps Street View) in regards
to the proposed child care centre site there are:

* No easements benefitting Endeavour Energy (active easements are
indicated by red hatching).
* Low voltage and 11,000 volt / 11 kilovolt (kV) high voltage overhead
power lines to the opposite side of Rooty Hill Road South.
* Low voltage overhead power lines crossing Rooty Hill Road South to a
streetlight located in proximity of the site.

Please note the location, extent and type of any electricity
infrastructure, boundaries etc. shown on the plan is indicative only.
Generally (depending on the scale and/or features selected), low
voltage (normally not exceeding 1,000 volts) is indicated by blue
lines and high voltage (normally exceeding 1,000 volts but for
Endeavour Energy's network not exceeding 132,000 volts / 132 kV) by
red lines (these lines can appear as solid or dashed and where there
are multiple lines / cables only the higher voltage may be shown).
This plan only shows the Endeavour Energy network and does not show
electricity infrastructure belonging to other authorities or customers
owned electrical equipment beyond the customer connection point /
point of supply to the property. This plan is not a `Dial Before You
Dig' plan under the provisions of Part 5E `Protection of underground
electricity power lines' of the Electricity Supply Act 1995 (NSW).

Subject to the foregoing and the following recommendations and
comments (having regard that, Endeavour Energy has no objection to the
Modification Request.

* Earthing

The construction of any building or structure (including fencing,
signage, flag poles, hoardings etc.) whether temporary or permanent
that is connected to or in close proximity to Endeavour Energy's
electrical network is required to comply with Australian/New Zealand
Standard AS/NZS 3000:2018 `Electrical installations' as updated from
time to time. This Standard sets out requirements for the design,
construction and verification of electrical installations, including
ensuring there is adequate connection to the earth. Inadequate
connection to the earth to allow a leaking/fault current to flow into
the grounding system and be properly dissipated places persons,
equipment connected to the network and the electricity network itself
at risk from electric shock, fire and physical injury.

In regards to a child care centre, Endeavour Energy's Substation
Primary Design Section have previously provided the following comments
for a development application involving the construction of a child
care centre with a padmount substation located on the site.

Endeavour Energy's `Design certification checklist for ASP L3' the
design must comply with Endeavour Energy's `Earthing Design
Instruction EDI 001 - Earthing design risk assessment' in which child
care centres are regarded as a `special location' - please see the
following extract of EDI 001.



If the child care centre is in proximity of a padmount substation, the
applicant should check with the proponent and their ASP responsible
for the network connection to the site that any padmount substation
earthing has been designed to comply with the `special location'
requirements under EDI 100 ie. at the time the ASP did the design they
may not have been aware of the intended use of part of the site as a
child care centre.

* Prudent Avoidance

The electricity network is operational 24/7/365 ie. all day, every day
of the year. The electricity industry has adopted a policy of prudent
avoidance by doing what can be done without undue inconvenience and at
modest expense to avert the possible risk to health from exposure to
emissions form electricity infrastructure such as electric and
magnetic fields (EMF) and noise which generally increase the higher
the voltage ie. Endeavour Energy's network ranges from low voltage
(normally not exceeding 1,000 volts) to high voltage (normally
exceeding 1,000 volts but not exceeding 132,000 volts / 132 kV).

In practical terms this means that when designing new transmission and
distribution facilities, consideration is given to locating them where
exposure to the more sensitive uses is reduced and increasing
separation distances. These emissions are generally not an issue but
with Council's permitting or encouraging development with higher
density, reduced setbacks and increased building heights, new
development can impact on existing electricity infrastructure. Where
development is proposed in the vicinity of electricity infrastructure,
Endeavour Energy is not responsible for any amelioration measures for
such emissions that may impact on the nearby proposed development.
Endeavour Energy believes that likewise Council should also adopt a
policy of prudent avoidance by the siting of more sensitive uses away
from any electricity infrastructure - including any possible future
electricity infrastructure required to facilitate the proposed
development.

Please find attached a copy of Energy Networks Association's `Electric
& Magnetic Fields - What We Know, January 2014' which can also be
accessed via their website at http://www.ena.asn.au/.

Electric fields are strongest closest to their source, and their
strength diminishes rapidly as we move away from the source.

The level of a magnetic field depends on the amount of the current
(measured in amps), and decreases rapidly once we move away from the
source.

Typical magnetic field measurements associated with Endeavour Energy's
activities and assets given the required easement widths, safety
clearances etc. and having a maximum voltage of 132,000 volt / 132 kV,
will with the observance of these separation distances not exceed the
recommended magnetic field public exposure limits.

Endeavour Energy's Network Environment Assessment Section has provided
the following advice for a child care centre proposed in proximity of
existing electricity infrastructure.

As far as I know there are no restrictions in legislation that stop a
child care centre being placed next to an easement for electricity
infrastructure.

Prudent avoidance measures must however be implemented. Prudent
avoidance was a policy recommended by former Chief Justice of the High
Court of Australia, Sir Harry Gibbs, as a result of an inquiry he
conducted into community needs and high voltage transmission lines
including issues in relation to EMF back in 1991. The findings in the
Gibbs report are consistent with subsequent inquiries and are still
relevant today.

Prudent avoidance is defined as doing what can be done without undue
inconvenience and at modest expense to avert the possible risk to
health from exposure to new high voltage transmission facilities. In
practical terms, this means designing new transmission and
distribution facilities having regard to their capacity to produce
EMFs, and siting them having regard to the proximity of houses,
schools and the like.

Although the Gibbs report was particularly aimed at electricity
distributers to consider when placing their infrastructure, and
bearing in mind that there are childcare centres and schools adjacent
to our infrastructure in various locations right across our franchise
area, it is nonetheless Endeavour Energy's recommendation it that a
child care centre not be built adjacent to electricity infrastructure.

Should such a development proceed, the design of the child care centre
should also consider prudent avoidance measures such as any rooms
which the children will occupy (play areas, sleeping rooms, eating
areas) be arranged such that they are on the side of the site/building
which is furthest away from the electricity infrastructure.

I appreciate that not all the foregoing issues may be directly
relevant or significant to the Modification Request ie. there may end
up being no significant / high voltage electricity infrastructure on
or in proximity of the child care centre site. However, Endeavour
Energy's preference is to alert proponents / applicants of the
potential matters that may arise should development within closer
proximity of the existing and/or required electricity infrastructure
needed to facilitate the proposed development on or in the vicinity of
the site occur.

Could you please pass on a copy of this submission and the attached
resources to the applicant? Should you wish to discuss this matter, or
have any questions, please do not hesitate to contact me or the
contacts identified above in relation to the various matters. Due to
the high number of development application / planning proposal
notifications submitted to Endeavour Energy, to ensure a response
contact by email to [email protected] is
preferred.
