Executive Summary
Need for the Proposal
Transport for New South Wales (TfNSW) currently operates an analogue train radio system
known as MetroNet for operational communications between signallers and train drivers. This
system has reached the end of its serviceable life and requires replacement. The New South
Wales Government and TfNSW have begun work on the implementation of a Digital Train Radio
System (DTRS) which will replace this analogue system and address a number of
recommendations from the Waterfall Special Commission of Inquiry. The DTRS will be a secure
digital train radio system designed to provide reliable voice and data communications on a
Global Systems Mobile – Railway (GSM-R) platform.
The DTRS will provide 100% radio coverage across the 1,455 kilometre electrified rail network.
The DTRS has an expected design life of at least 15 years. UGL Infrastructure has been
contracted to design, construct, commission and maintain the DTRS.
Proposal Description
The Stanwell Park Tunnel distributed base station (DBS) includes a new outdoor DBS at
Location 1, and a Yagi antenna mounted to the west portal of Stanwell Park Tunnel at Location
2. Location 1 is located about 390 metres east of Stanwell Park station in a cleared, grassy area
about 100 metres from the east portal of the Stanwell Tunnel.
The proposed work will involve the elements listed below.
• A 10 metre high hinged mast at Location 1;
• Two Yagi antennas mounted on the hinged mast;
• DBS cabinet on a slab two metres from the hinged mast;
• One Yagi antenna mounted on an antenna support to the west portal of the Stanwell Park
Tunnel at Location 2;
• Leaky feeder to be installed at the crown of the tunnel running approximately 150 metres
through the tunnel;
• Power is yet to be determined. It will be subject to additional approvals;
• Conduit feeder cables to connect to the fibre supply, installed at a depth of at least 600
millimetres; and
• Other associated and necessary activities to ensure the proper functioning of the radio
communications facility including earthing, safe access, signage and bollards for vehicle
protection.
Page 4 of 72

Approval Process
The proposal is being assessed under Part 5 of the Environmental Planning and Assessment
Act 1979 (EP&A Act) which requires TfNSW to consider the environmental impacts of the
proposal.
This Review of Environmental Factors (REF) has been prepared to address the requirements of
the EP&A Act. It assesses the potential environmental impacts of the proposal within the
context of Clause 228 of the Environmental Planning and Assessment Regulation 2000 (EP&A
Regulation) and the Threatened Species Conservation Act 1995 (TSC Act). The requirements
of the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC
Act) are also considered.
Environmental Impact Assessment
The benefits of the proposal cannot be achieved without some degree of environmental impact.
The impacts resulting from construction and operation of the facility have been assessed in this
REF. This REF identifies that, subject to the implementation of mitigation measures, potential
environmental impacts can be controlled and reduced to acceptable levels and will not
significantly affect the environment.
The main environmental issues relate to construction impacts such as erosion and
sedimentation risks as well as short-term traffic, air quality and noise issues for nearby
receivers. Such impacts will be managed through the implementation of a program wide
Construction Environmental Management Plan (CEMP) and site specific Environmental Control
Map (ECM).
In the long term, a new tilted mast will be introduced into the visual landscape. The hinged mast
and its antennas will not be bulky and will be completely screened by vegetation along the rail
corridor. The sites will not be visible to residential receivers. Electromagnetic energy (EME)
impacts have also been considered and the EME levels for the proposal will be well within the
limits set by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).
Environmental Management
Following determination of the project, construction works will be undertaken in accordance with
the program wide CEMP and site specific ECM. The CEMP and ECM will further detail REF
mitigation measures and will be prepared in accordance with the following:
Guideline for the Preparation of Environmental Management Plans (Department of
Infrastructure, Planning and Natural Resources, 2004)
The Environmental Management Plan for DTRS (UGL Infrastructure, 2010)
TfNSW Guide to Environmental Control Map (2012).
The following sub-plans are proposed in the REF and will be prepared concurrently with the
CEMP and/or ECM as appropriate:

Erosion and Sediment Control Plan
Water Management Plan
Waste Management Plan
Traffic Management Plan.
The program wide CEMP has been approved by TfNSW. The site specific ECM will be
reviewed and approved by TfNSW prior to the commencement of construction.

1 Introduction
1.1 Background to the Project
TfNSW currently operates an analogue train radio system known as MetroNet for operational
communications between signallers and train drivers. This system has reached the end of its
serviceable life and requires replacement. The New South Wales Government and TfNSW have
begun work on the implementation of a Digital Train Radio System (DTRS) which will replace
this analogue system and address a number of recommendations from the Waterfall Special
Commission of Inquiry regarding communications in NSW rail operations and within RailCorp.
Following the establishment of TfNSW, RailCorp became an operating agency within TfNSW.
TfNSW is now the proponent for the DTRS.
The primary objectives of the DTRS project are to:
Provide continuous radio coverage across the entire electrified rail network
Replace and improve on the current MetroNet communications system
Provide a technology platform for future development of the Automatic Train Protection
system
Adopt best management and administrative practices while complying with the principles of
ecologically sustainable development.
The DTRS will provide secure and reliable voice and data communications via a Global
Systems Mobile – Railway (GSM-R) platform. It will be used by train controllers, train drivers,
train guards and signallers. The system is designed to allow for growth in both the size of the
network and the number of services using it. It will be compatible with communications systems
used by other users of the network, e.g. freight operators.
The DTRS will provide 100% radio coverage along approximately 1,455 kilometres of the
electrified rail network, including along approximately 70 kilometres of tunnel, and has an
expected design life of at least 15 years.
The DTRS will include:
A main switching centre at a CBD location
A geographically separated back-up switching centre at Homebush
On-train equipment in approximately 675 train cabs
About 250 base transceiver stations as well as other base stations in tunnels
Approximately 65 dispatcher terminal units
Capability to provide staff with handheld terminals.
Page 7 of 72

The DTRS will provide continuous radio coverage across the entire electrified rail network for
on-train radios and permit at least 14 simultaneous voice calls from each base station.
DTRS systems are now widely used as a standard by major rail operators in Europe and Asia.
In Australia, GSM-R is being installed on the Melbourne train network by the Victorian
Government.
1.2 Background to the Stanwell Park Tunnel site
The proposed distributed base station at Stanwell Park Tunnel is part of the DTRS that is being
developed along the electrified rail lines. The proposal at Stanwell Park Tunnel includes a new
10 metre tilted mast and two attached Yagi antennas at Location 1 and a Yagi antenna mounted
at Location 2. The proposal will provide coverage between the Stanwell Park Tunnel South
Portal DBS site and Tree Tops DBS Site.
The Stanwell Park Tunnel DBS locations are one of about 250 radio facilities which will provide
an enhanced, efficient and reliable communication system for the electrified railway network.

Stanwell Park
The proposed hinged mast at Location 1 is on the southern side of the rail corridor about 390
metres east of Stanwell Park Station (refer Figure 1, 2 and 3). Location 1 is in a cleared, grassy
area about 100 metres from the east portal of the Stanwell Park Tunnel.
The sites are within the Wollongong Local Government Areas (LGA). The proposed work will be
undertaken on land in Zone SP2 – Rail corridor.
Land around the sites is used for the purposes listed below.
• To the north and west is the rail corridor followed by dense bushland associated with the
Illawarra State Conservation Area and Stanwell Park Coastal Conservation Area and
further north, the Garden of Peace.
• To the south is dense bushland with a small clearing approximately 200 metres away, and
then railway line beyond. To the southeast is a residential dwelling approximately 220
metres from the proposed Location 1.
• To the east is a small area of bushland and the Stanwell Park Station, followed by the
township of Stanwell Park.
• There are no child care centres, aged care facilities, schools or hospitals within 500 metres
of the proposed site.
Page 9 of 72

There is adequate vehicle access to both locations via a dirt road off Railway Crescent and the
access track is suitable for construction vehicle access.
Stanwell Park Rail Viaduct over Stanwell Creek is a state and locally listed heritage item and is
located approximately 70 metres west of Location 2 and approximately 270 metres west of
Location 1. The Stanwell Park Underbridge forms part of the Railway Viaduct and is a local and
state listed heritage item. No works will be undertaken within the curtilage of these items.
Mature trees surround the site along the railway corridor however both site locations are located
within previously cleared grassy areas. In addition all areas of new trenching are also located
within cleared grassy areas. RailCorp Biodiversity Mapping indicates Location 1 is within an
area of slashing and Location 2 is within an area of medium height weeds.
The closest waterway is the Stanwell Creek located roughly 116 metres to the southwest of
Location 2 and 230 metres southwest of Location 1 and flows into the Tasman Sea.

1.4 Consultation
The consultation activities for the proposed work are outlined below. These measures are
designed to assist in informing stakeholders of the proposal. These activities also assist TfNSW
in meeting its obligations under the State Environmental Planning Policy (Infrastructure) 2007
(ISEPP). Consultation activities and work practices will be undertaken in accordance with
community relation protocols and requirements as per TfNSW’s Communications Management
Plan.
Three main consultation activities will take place.
1) Communication with local councils and other regulatory authorities
Consultation with the local council and other regulatory authorities is required by the ISEPP.
Council and any relevant government authorities will be contacted and a link to this document
provided.
2) Communication with residents and businesses within a 500 metre radius of works
Consultation with nearby residents, schools and other community facilities is required. A
number of consultation activities will be undertaken and are outlined below.
Page 12 of 72

A letter will be sent to all properties within a 500 metre radius detailing the DTRS project
and the scope of works proposed for the Stanwell Park Tunnel DBS site. The letter will also
provide advice on where copies of the REF can be viewed.
This REF will be on public exhibition for 21 days. The REF will be accessible via
www.transport.nsw.gov.au/projects.
• Face to face consultation will be undertaken with nearby residents. Residents will be
advised of the proposal and provided with information about where they can obtain the
REF and the mechanisms via which they can provide feedback.
• A project information line will be established for the community to obtain further information
during business hours.
Community relations for the Stanwell Park Tunnel DBS proposal will specifically be targeted at:
• Residents along Railway Crescent and part of Lawrence Hargrave Drive.
• There are no community facilities within 500 metres of the proposed site.
3) Notification and community relations prior to construction, during construction and
during commissioning works with Council and nearby community.
Subject to planning approval, the nearby community and Council will be advised of the
determination.
The nearby community and Council will also be provided with notification at least five days
before any construction work/site establishment work begins. This information will include
specific detail regarding activities, works hours, traffic control measures and
compound/assembly location.
Further consultation with the community during this phase of project may also include face-toface
communication with nearby community members.
Summary
Feedback received during pre-construction consultation will be taken into consideration and
included in the project determination report. This report, along with the REF, will be used to
determine whether the development should process and what, if any, changes need to be
made.

2 Statutory Position and Requirements
The description of the proposed works and the associated environmental impacts has been
undertaken in the context of Clause 228 of the Environmental Planning and Assessment
Regulation 2000 (EP&A Regulation), the Threatened Species Conservation Act 1995 (TSC Act),
and the (Commonwealth) Environment Protection and Biodiversity Conservation Act 1999
(EPBC Act). In doing so, this REF helps fulfil the requirements of Section 111 of the
Environmental Planning and Assessment Act 1979 (EP&A Act), that TfNSW must examine and
take into account, to the fullest extent possible, all matters affecting or likely to affect the
environment by reason of the activity. The legislative framework relevant to the proposed works
and associated approvals is set out in the following sections.
2.1 Environmental Planning and Assessment Act 1979
The proposal comprises an ‘activity’ for the purposes of Part 5 of the EP&A Act. As the
determining authority for the purposes of Part 5 of the EP&A Act, TfNSW must examine and
take into account to the fullest extent possible all matters affecting or likely to affect the
environment by reason of that activity, in accordance with section 111 of the EP&A Act.
To document TfNSW’s considerations under Part 5 of the EP&A Act, TfNSW is required to
prepare a Review of Environmental Factors (REF), which includes mitigation measures to
manage and minimise impacts on the environment. The REF document will be exhibited and
made publicly available. During the exhibition period, the community are encouraged to make
submissions to TfNSW on the proposal and any potential environmental impacts.
Prior to determining whether or not to proceed with the project, TfNSW will consider issues
raised in submissions and respond to community feedback. TfNSW may propose changes to
the proposal and detail these in the determination report. The determination report will be made
available to the public on the TfNSW website (www.transport.nsw.gov.au/projects).
Should TfNSW determine to proceed, the proposal will be constructed and operated in
accordance with the mitigation measures proposed in the REF, determination report and any
conditions of approval.

2.2 State Environmental Planning Policy (Infrastructure) 2007
The State Environmental Planning Policy (Infrastructure) 2007 (ISEPP) provides a consistent
planning regime for infrastructure and the provision of services across NSW, along with
providing for consultation with relevant public authorities during the assessment process.
The ISEPP provides for the development of certain activities for a range of infrastructure types.
The ISEPP indicates whether an activity is permissible with or without consent, and on what
land the activity is permissible.
Section 76 of the EP&A Act states that “if an environmental planning instrument provides that
specified development may be carried out without the need for development consent, a person
may carry the development out, in accordance with the instrument, on land to which the
provision applies.” However environmental assessment of the development may nevertheless
be required under Part 5 of the EP&A Act.
2.3 Confirmation of Statutory Position
Clause 79(1) of the ISEPP provides:
“Development for the purpose of a railway or rail infrastructure facilities may be
carried out by or on behalf of a public authority without consent on any land.”
The proposal is for the installation of a new base transceiver station (new hinged mast,
antennas and power and DBS cabinets), which is consistent with the definition of a rail
infrastructure facility under Clause 78, which includes “signalling, train control, communication
and security systems”.
In addition Clause 114(1) provides:
“Development for the purposes of telecommunications facilities (including radio
facilities) may be carried out by a public authority without consent on land.”
The proposal also meets the definition of a telecommunication facility under Clause 113 of the
ISEPP. TfNSW is classified as a public authority under Section 4 of the EP&A Act.
Accordingly, this proposal (construction of a new DBS at Stanwell Park Tunnel) is being
assessed under Part 5 of the EP&A Act. TfNSW is the proponent and determining authority as
per the provisions of Section 110 of the EP&A Act.

2.4 Other Relevant Environmental Planning Instruments
State Environmental Planning Policy No. 14 – Coastal Wetlands
The proposed site is not located within an area covered by the SEPP and therefore no further
consideration of SEPP 14 is necessary.
State Environmental Planning Policy No. 19 – Bushland in Urban Areas
This SEPP protects and preserves bushland within certain urban areas, as part of the natural
heritage or for recreational, educational and scientific purposes.
Wollongong LGA is not listed in Schedule 1 as an area where bushland needs to be preserved
so no further consideration of this SEPP is required.
State Environmental Planning Policy No. 26 – Littoral Rainforests
The proposed sites are outside the littoral protection areas designated in the Littoral Rainforests
SEPP, so no further consideration of this SEPP is required.
State Environmental Planning Policy No. 44 – Koala Habitat Protection
Wollongong LGA is listed in Schedule 1 as an area possessing habitat or feed trees for koalas.
However, the proposed work will not require the removal of koala habitat or feed trees, so no
further consideration of this SEPP is required
State Environmental Planning Policy No. 55 – Remediation of Land
SEPP 55 provides for a consistent state-wide planning approach to the remediation of
contaminated land. The policy states that land must not be developed if it is unsuitable for a
proposed use because it is contaminated. If the land is unsuitable, remediation must take place
before the land is developed. The presence of contamination will be determined during
excavation works and a suitable remediation plan will be developed, if required.
State Environmental Planning Policy No. 71 – Coastal Protection
The proposed sites are within the coastal protection zone designated in the Coastal Protection
SEPP. Due to the nature and scale of the proposed works along with the control measures laid
out in Section 4, the proposed works will not compromise the aims of the coastal protection
policy. No further consideration of the SEPP is required.
State Environmental Planning Policy (Major Development) 2005
This SEPP identifies certain developments which are deemed major projects. The proposal is
not listed in this SEPP.
State Environmental Planning Policy (State and Regional Development) 2011
The proposal is not listed in the SEPP and has not been declared as State Significant
Infrastructure or State Significant Development under the SEPP.
Page 16 of 72

State Environmental Planning Policy (Sydney Drinking Water Catchment) 2011
The site is in the Tasman Sea catchment and is not part of a drinking water catchment. This
SEPP does not apply to the proposal.
Wollongong Local Environmental Plan 2009
The proposed site is in the Wollongong LGA and is subject to the Wollongong Local
Environmental Plan 2009 (Wollongong LEP). The proposed works will be undertaken in the rail
corridor, which is in Zone SP2 – Infrastructure.
Development that is ordinarily incidental or ancillary to development for that purpose is
permissible in Zone SP2 - Infrastructure with consent, under Part 2 of the Wollongong LEP.
As the ISEPP overrides the development consent requirements of any LEP, the proposal can
proceed without development consent (refer Section 2.2 and Section 2.3 for more detail).
2.5 Other NSW Legislation
Crown Lands Act 1989
The proposed work will not be undertaken on Crown land and the provisions of this Act are not
applicable to the proposal.
Electricity Supply Act 1995
The Electricity Supply Act 1995 and Electricity Supply (General) Regulation 2001 set out certain
notification and procedural requirements in relation to excavation.
Section 63Z provides:
(1) A person must not commence to carry out excavation work to which this section
applies, or authorise such excavation work to be commenced, unless the person has
first:
(a) contacted the designated information provider and requested information as to the
location and type of underground electricity power lines in the vicinity of the proposed
work, and
(b) complied with reasonable procedures of the designated information provider as to
the manner of contacting the designated information provider and the information to be
provided by the person in connection with the person’s request for information, and
(c) allowed a reasonable period for the requested information to be provided.
Clause 104B of the Electricity Supply (General) Regulation 2001 provides:
(1) Work of the following kind that is carried out within the distribution district of a
distribution network service provider is excavation work to which section 63Z of the Act
applies…
Page 17 of 72

(b) excavation that is, or is carried out in connection with, an activity within the meaning
of Part 5 of the Environmental Planning and Assessment Act 1979.
Consultation with the relevant service provider will occur in accordance with these provisions.
Heritage Act 1977
Section 57(1) of the Heritage Act 1977 lists the types of activities/works that require approval
from the Heritage Council when working on/in an item/place listed on the State Heritage
Register. An application for an exemption can also be made under some circumstances.
Approval from the Heritage Council is also required under Section 139 of the Heritage Act 1977
prior to the disturbance or excavation of land if a project will, or is likely to result in, a relic being
discovered, exposed, moved, damaged or destroyed.
The proposed work is to be undertaken about 70 metres from Stanwell Park Rail Viaduct, which
is listed as a state heritage item; however the proposed work is not within its heritage curtilage.
Therefore approval under the Heritage Act is not required. More information about heritage is
included in Section 4.6.
National Parks and Wildlife Act 1974
The excavating, moving or exhibiting of Aboriginal objects requires a permit under Section 87 of
the National Parks and Wildlife Act 1974 (NPW Act). The harming or desecrating of Aboriginal
objects or places is an offence under Section 86 of the NPW Act. Under Section 90, an
Aboriginal heritage impact permit may be issued in relation to a specified Aboriginal object,
Aboriginal place, land, activity or person or specified types or classes of Aboriginal objects,
Aboriginal places, land, activities or people.
There are no Aboriginal objects or places known to occur in the immediate vicinity of the site
and no known items or places will be affected by the proposed work. However, due to the dense
and undisturbed nature of the bushland surrounding the site, the likelihood of uncovering
Aboriginal heritage items is considered moderate (refer Section 4.6). Safeguards have been
proposed to address circumstances if an unexpected find occurs.
All native birds, reptiles, amphibians and mammals, except the dingo, are protected in NSW
under the NPW Act. The harming of protected fauna is prohibited under the NPW Act, but an
exemption applies in relation to things that are essential to the carrying out of an activity to
which Part 5 of the EP&A Act applies and where the determining authority has complied with
the provisions of that part. Potential impacts to fauna are considered in Section 4.4.
Protection of the Environment Operations Act 1997
The Protection of the Environment Operations Act 1997 (POEO Act) provides a licensing
framework for certain activities as defined in Schedule 1 of the POEO Act. The proposal is not
considered to fall within the definition of Section 33 ‘Railway systems activities’ of Schedule 1.
As such, the proposal does not require an environment protection licence (EPL) under the
POEO Act.
Page 18 of 72

Roads Act 1993
Under Section 138 of the Roads Act 1993, a person must not “erect a structure or carry out a
work in, on or over a public road, or dig up or disturb the surface of a public road...” other than
with the consent of the appropriate roads authority. However, clause 5(1) in Schedule 2 of the
Act states that public authorities do not require consent for works on unclassified roads.
The proposal does not require any work to be undertaken in, on or over a classified road.
Therefore, approval from Roads and Maritime Services (RMS) will not be required.
Threatened Species Conservation Act 1995
The Threatened Species Conservation Act 1995 (TSC Act) is directed at conserving threatened
species, populations and ecological communities of animals and plants. Due to the dense and
undisturbed nature of the bushland surrounding the site, there is potential for threatened
species, populations, and endangered ecological communities to occur at the site. However, the
removal or pruning of native tree species is not proposed and control measures will be put in
place to ensure that there will be no impact on threatened species, populations and ecological
communities of animals and plants and further consideration under the Act is not required.
Native Vegetation Act 2003
The Native Vegetation Act 2003 (NV Act) manages the clearing of native vegetation in NSW.
Section 25(g) of the NV Act provides that any clearing that is part of an activity that is
permissible without consent does not require approval under the Act.
Nevertheless, RailCorp’s guideline for vegetation management in rail corridors provides a
framework for compliance with this Act.
No native vegetation will be affected as part of the proposed works.
2.6 Commonwealth Legislation
Environment Protection and Biodiversity Conservation Act 1999
The primary legislation at the Commonwealth level is the Environment Protection and
Biodiversity Conservation Act 1999 (EPBC Act). Part 3 of the EPBC Act requires approval from
the Commonwealth Minister for Sustainability, Environment, Water, Population and
Communities if a development is likely to have, or will have, a significant effect on a matter of
National Environmental Significance (NES).
For the purposes of the EPBC Act, matters of NES are defined as:
• world heritage properties;
• national heritage places;
• Ramsar wetlands;
• nationally threatened species and ecological communities;
Page 19 of 72

• migratory species;
• commonwealth marine areas; and
• nuclear actions.
The proposed work will not affect any matters of national environmental significance.
Commonwealth land will not be affected, either directly or indirectly, as a result of this proposal.
A summary of EPBC factors is included in Table 4.
Commonwealth Telecommunications Act
To operate the DTRS, TfNSW will have a Telecommunication Licence and so will have certain
rights under the relevant Commonwealth Legislation. In particular, TfNSW will be able to install
low impact facilities without reference to local or state approvals processes.
However, the Telecommunications (Low-impact Facilities) Determination 1997 defines a low
impact facility as:
Panel, Yagi or other like antenna:
(a)
Not more than 2.8 metres long; and
(b) If the antenna is attached to a structure — protruding from the structure by not more than
three metres.
Since this DTRS site includes the installation of a pole greater than three metres, it is not a low
impact facility and so will be assessed under Part 5 of the EP&A Act.
2.7 Ecologically Sustainable Development
Ecologically sustainable development (ESD) entails using, conserving and enhancing the
community’s environmental resources in a manner that sustains and improves ecological
processes and, hence, the quality of life for present and future generations. The basis for
achieving ESD involves the application of four principles:
the precautionary principle;
intra- and inter-generational equity;
conservation of biological diversity and ecological integrity; and
improved valuation and pricing of environmental resources.
TfNSW is committed to ensuring its projects are consistent with the principles of ESD and these
have been considered for this proposal (refer Table 1).

Table 1
Consideration of ESD for the proposal
ESD Principle
Application to the proposal
Precautionary principle
The site selection and design process aims to avoid areas where
there will be a significant environmental impact or impacts that are
irreversible. The site selected is within a previously disturbed area
in the rail corridor. In addition, some of the potential impacts are
reversible as the hinged mast and cabinets can be removed if no
longer required.
Adverse impacts associated with the site and construction will be
minor and measures to reduce impacts identified within this REF
will be implemented during construction, as far as practicable.
Intergenerational equity
This proposal and the overarching DTRS project will contribute
towards TfNSW’s strategic benefits for current and future
generations, including safer public transport, by improving on the
current communications system, providing coverage and reliable
communications services to all parts of the electrified rail corridor
and acting as the basis for the introduction of an Automatic Train
Protection System.
The economic, social and safety considerations of the DTRS have
been integrated with the consideration and assessment of
potential environmental impacts regarding the development and
operation of the DTRS.
Conservation of
biological diversity and
ecological integrity
The proposed site is on disturbed land that has been previously
cleared. Major clearing or other disturbance to the biodiversity or
items of ecological significance of the area is not required. The
proposed activity is not expected to result in loss of biodiversity or
ecological integrity.
Improved valuation and
pricing of environmental
resources
TfNSW recognises the value of environmental sustainability and
will minimise the impact of its activities by ensuring appropriate
mitigation measures are implemented for all aspects of the DTRS
project. The potential environmental costs of the proposal have
been considered in conjunction with the costs of design,
construction and operation.

3 Description of the Proposal
3.1 Scope of Proposed Works
3.1.1 Summary
The outdoor DBS site at Stanwell Park Tunnel will consist of the following components:
A 10 metre high hinged mast at Location 1;
Two Yagi antennas mounted on the hinged mast;
DBS cabinet on a slab two metres from the hinged mast;
One Yagi antenna mounted nine metres high to the west portal of the Stanwell Park Tunnel
at Location 2;
Leaky feeder to be installed through the tunnel for approximately 150 metres; and
Power is yet to be determined. It will be subject to additional approvals.
fibre
These components are described in the sections below. Plan drawings are provided in
Appendix 2. All aspects of the proposal will be earthed in line with all relevant standards.
3.1.2 DBS Site
The DBS cabinet will be placed on a precast concrete slab and will be oriented to the east. The
cabinet will be approximately 1,700 millimetres high by 1,000 millimetres long by 880 millimetres
wide, and will be placed on a steel plinth with a minimum height of 200 millimetres to allow for
the management of cables entering the cabinet. The DBS cabinet will include the following
equipment:
DBS equipment (transceiver modules, transmission equipment, controller etc.);
Direct current (DC) distribution (including electromagnetic interference filter and surge
protection);
Transmission interface (Huawei PTN910);
Fibre optic distribution frame;
6 Ethernet Ports for RailCorp’s use; and
Field monitoring device for radio frequency coverage. This requires a 12V DC input so is
installed with a 48V to 12V DC power converter.
The cabinet will also house the power equipment including:
Alternating current (AC) and earth terminations;
Page 23 of 72

Transfer switch (mains and generator positions);
Surge protection;
General purpose outlet;
Low voltage disconnect;
Rectifier modules;
Controller/supervisory module;
DC distribution rack; and
Batteries (with the capability of providing a minimum of four hours’ back-up).
3.1.3 Hinged Mast
A 10 metre tilted mast will be erected approximately two metres to the northwest of the DBS
cabinet in the rail corridor. Two Yagi antennas will be mounted 10 metres above the ground with
azimuths of 65° and 275°. The antennas will be installed to have a zero degree tilt, but will be
able to be remotely adjusted to different degrees of tilt, without the need to climb the hinged
mast for such adjustments. Location 2 will include one Yagi antenna pole mounted on west end
portal at nine metres with an azimuth of 215°.
3.1.4 Power Supply
Power is yet to be determined. It will be subject to additional approvals.
3.1.5 Fibre Optics and Leaky Feeder
Fibre will be connected from Location 1 to the existing pit near the north-eastern end of tunnel
portal via the conduit located within the tunnel. Approximately 100 metre trenching is required to
connect the fibre from the cabinet to the conduit at the tunnel portal
Fibre will run through an existing route from the existing pit near north-eastern end of the tunnel
portal to the existing pit near south-western end of the tunnel portal, and then back to DTRS
network. No native vegetation will be removed, only grass will be cleared.
3.1.6 Earthing
The earthing installation will comprise six earth stakes at a pre-determined distance apart. The
grid will be nominally four by two metres; placing the six earth stakes two metres apart. Once
these earth stakes have been installed, the system will be tested and modified if needed. The
initial extent of the trenching for earthing grid will be around 20 metres. However, it can be
extended up to five metres if the results show that the earthing arrangement is insufficient.
3.2 Construction Methodology
Construction on the DBS facility will require the use of approximately 200 square metres of land
for Location 1 within the eastern side of the rail corridor. This area will allow for the erection of
the hinged mast and the slab containing the DBS cabinet.
Page 24 of 72

Construction on the DBS facility will require the use of approximately 50 square metres of land
for Location 2 within the eastern side of the rail corridor.
The area of ground disturbance at the Location 1 is likely to be in the vicinity of five square
metres. The hinged mast foundation will require an excavation approximately five metres deep
with a diameter of one metre. This will result in approximately five cubic metres of excavated
material which may include rock.
Installation of the fibre optic cables at Location 1 will require excavation of trenches
approximately 100 metres long and approximately 500 millimetres deep and 1,000 millimetres
wide. Approximately three metres of trenching will be required to run fibre cables from the DBS
cabinet to a new half pit near chainage SW56+466. Approximately 95 metres of trenching will
be required to run from the new half pit towards another half pit at near chainage SW56+541
and approximately two metres of trenching will required to connect from this half pit towards an
existing pit. It is expected there will be no impacts to native vegetation as none will be removed.
At Location 2, an elevated work platform with hi-rail function will be used to install the mast at
the west portal. Drilling will be required on the wall for mounting the mast.
The indicative construction methodology of the facility will include elements outlined below.
Non-destructive excavation before construction to establish underground installations.
Site establishment.
Excavation of the foundation for the hinged mast using excavator, drills or auger.
Delivery and pouring of concrete on site for the hinged mast foundation.
Installation of concrete slab brought to site for DBS cabinet.
Excavation of trenches for power and fibre optic cables.
Installation of conduit within trenches, followed by installation of cables within conduits.
Backfilling of trenches.
Transport and installation of the hinged mast sections using trucks and riggers.
Assembly of the hinged mast and attachment of antenna mounts and cables before erection
of the pole using the built in hinge joint.
Connection of fibre optic cables to the transformer and communications pit, respectively.
Installation of earth grid using drills, shovels or excavator and connection of the radio facility
to the electrical supply and optical fibre communications cable.
Installation and commissioning of radio equipment, batteries, antennas, cables and other
equipment.
Page 25 of 72

Materials used for construction and installation include concrete, gravel, a steel plinth, steel
mounts, antennas, batteries, cables and radio equipment. It is not envisaged that chemicals or
hazardous materials will be used during construction.
The majority of material brought to the site will remain there once installed. Excess material will
be removed and reused, recycled or disposed of. Any excess concrete will be removed. All
excavated material not required for backfilling will be stockpiled, removed from site and
disposed of at a licensed facility.
The following equipment will potentially be used during construction.
Pile borer
Hiab truck 10T
Trencher (chain digger)
Excavators
Bobcat
Vacuum excavator (Sucker Truck)
Wacker packer
Earth rod drill
Concrete delivery truck
Delivery truck VLC (semi-trailer)
1.5 tonne come-a-long
17 metre sling
Assorted slings and shackles
Assorted large spanners and hand tools
Hydraulic pack and ram
Portable generator (with RCD)
Cable stripping tools
Hydraulic hole punch (sized to suit cable gland)
Crimpers ratchet type
Battery drill
Multimeter
Electrical hand tools
Hand digging tools (shovels etc.)
Page 26 of 72

The skip bin and site compound area will be located within the rail corridor near the site if
required. The construction process will require an average of four to six vehicle movements and
a team of three to six people on site per day.
3.3 Timing and Costing
Construction is planned to begin in mid-year 2013 and construction activities will require four to
six weeks. The bulk of work may require to be undertaken in non-consecutive work days.
Proposed construction timing:
Standard working hours
Monday to Friday 7.00am to 6.00pm
Saturday 8:00am to 1:00pm
Evening/weekends/out of hours:
The leaky feeder and cable installation through
the tunnel will be carried out from 6:00am
Saturday 6 July 2013 to 6:00 pm Sunday 7 July
2013, during scheduled track possession.
The DTRS project has an overarching value of $225 million. This includes the design, supply,
and installation of the DTRS on the electrified network plus a five-year life support component.
3.4 Alternatives to the DTRS
A number of alternatives already used by the state government or available commercially were
investigated. The government alternatives were the existing MetroNet system or the
Government Radio Network (GRN).
The existing MetroNet communication system was not deemed a feasible solution for the
reasons listed below.
It uses out-dated technology and cannot be expanded due to its limited capacity.
It does not have the ability to support the requirements of Automatic Train Protection.
It only has one main supplier and this, combined with obsolete technology, means the cost
of using and maintaining the MetroNet system is increasing at a substantial rate.
It cannot facilitate a communications platform that can be used by all necessary TfNSW
personnel.
It cannot meet interoperability requirements.
The Department of Commerce’s Government Radio Network (GRN) was not deemed a feasible
solution for the reasons listed below.
It has to be shared with other NSW Government agencies.
Page 27 of 72

Priority is given to emergency services which could result in a failure of 100% radio
coverage across the rail network.
The network is both inside and outside the rail corridor.
GRN would require a substantial upgrade, including new base stations, to ensure 100%
radio coverage across the rail network.
The cost of this upgrade is comparable to the development of an entire new network.
The radio communications marketplace responded with three systems: APCO-25, Terrestrial
Trunked Radio (TETRA) and GSM-R.
APCO-25 is a proven standard for emergency services but was rejected for the reasons listed
below.
It has no proven history of usage in a rail environment.
It does not support a functional addressing system that maps train run numbers to mobile
subscribers’ numbers, which is a key requirement.
It does not meet the interoperability requirements.
It relies on a dispatch terminal for functionality, which does not meet TfNSW’s reliability
requirements.
It is not scalable in regard to the future growth of the rail network.
TETRA is also a proven emergency services communications system and is deployed in a
number metropolitan rail networks. However, it was rejected for the reasons listed below.
This application is confined primarily to underground metro networks that are not
comparable to the electrified rail network.
It relies on a dispatch terminal for functionality, which does not meet reliability requirements.
It does not meet the interoperability requirements.
There is no commercialised Automatic Train Protection (ATP) solution available.
GSM-R was deemed the platform most suitable for the electrified rail train network and system
requirements for the reasons listed below.
It is the only rail-specific communications standard and has the highest levels of safety and
reliability in its design.
It is an open standard with a large number of equipment suppliers.
It achieved a higher level of compliance with the TfNSW functional requirements when
compared to the other systems.
It is deployed by major rail operators in Europe and Asia, some with networks comparable
in size and complexity to the electrified rail network.
Page 28 of 72

It operates on a spectrum of 1800 MHz which was available for purchase by TfNSW. The
other options would have required the leasing of a radio spectrum from a
telecommunications licence holder.
It is a scalable network that can grow in step with the electrified rail operations and network.
It is compatible with the Australian Rail Track Corporation’s communication system.
It provides a platform for future enhancements and increased operational safety, including a
Level 2 Automatic Train Protection (ATP) System, as per the recommendations of the
Waterfall inquiry.
It will deliver the best value for money solution with the least risk.
3.5 Alternatives to the Stanwell Park Tunnel site
The following options were considered for the development of the Stanwell Park Tunnel site:
• To do nothing; or
• Install the antennas on existing communication facilities in the Stanwell Park Tunnel area.
The do nothing option was rejected for the reasons listed below.
• The inability to meet the requirement of 100% radio coverage across the electrified rail
network.
• A ‘black spot’ in the DTRS network, resulting in a significant safety issue in the event of an
emergency call or a train incident.
• The increasing maintenance costs of the MetroNet facility and the limited reliability for
adequate operation for the next 10 – 15 years.
None of the existing communications facilities were in a suitable position or offered the required
height to provide adequate coverage to the rail network, and as such were not selected for this
proposal.
Radio frequency modelling also indicated that a new DBS at Stanwell Park Tunnel Station
would not provide adequate coverage to the rail corridor. Another site would then be required,
increasing costs and environmental risks.
Other infrastructure options were considered, but were not feasible for the proposal.
• The proposed hinged mast is less obtrusive, requires less space and will be cheaper to
maintain than a lattice tower or guyed mast. A hinged mast also uses a foundation design
that is better suited given the spatial limitations within the rail corridor. The hinged mast is
thinner at the top and less obtrusive than a lattice tower, helping to minimise the visual
impacts of the proposal.
Page 29 of 72

• The hinged mast can be installed using a hinge mechanism, which removes the need for
large cranes.
• The installation of a walk-in equipment hut would use more space and be more expensive.
The use of outdoor cabinets was the most suitable solution given the limited space, cost
and minimisation of environmental impacts.
Alternative sites further north and further south were examined but were rejected due to the
following reasons:
• Installing poles/masts further north or south would create a gap in coverage to the leaky
feeders within the tunnel portal.
3.6 Justification of the Preferred Option
It was decided to construct a DBS approximately 360 metres west of Stanwell Park station
using GSM-R technology because it will enable the site to be consistent with the whole DTRS
network. Consistent technology choice will enable TfNSW to improve its existing quality of
service, reliability and emergency responsiveness.
The Stanwell Park Tunnel Location 1 site was selected due to its ability to cover the section of
track between the east end portal of Stanwell Park Tunnel to Stanwell Park and Location 2 was
selected for its ability to cover the section of track between the west end portal of the tunnel to
Tree Tops. The proposed antenna height of 10 metres at Location 1 and nine metres at
Location 2 is the minimum height required to provide optimum radio frequency coverage for
these sections of track.
The proposed site has good construction and maintenance access. The proposed work will not
require the removal of native vegetation.
In summary, a higher pole, or an additional DTRS facility would be required if the site was to be
relocated. It was decided that the preferred option would offer the least impact on the local
environment while still meeting operational requirements.

4 Environmental Impact and Risks
4.1 Landforms, Geology and Soils
Existing Situation
The proposed sites are inside the existing railway corridor. The Location 1 site is in a cleared,
grassy area and Location 2 is on an antenna support erected on the tunnel portal wall. The
geology comprises Clifton Subgroup of fine to medium-grained quartz-lithic sandstone to
lenticular shale interbeds. The soil is of the Watagan soil landscape type, which is comprised of
shallow to deep Lithosols/Siliceous Sands, and Yellow Podzolic soils on sandstones and steep
slopes.
NSW Acid Sulphate Soils (ASS) risk mapping provided by the NSW Office of Environment and
Heritage (OEH) indicates the proposed site is in an area of no known occurrences.
A desktop geological review was undertaken for this site. This review did not anticipate the
presence of ASS or contaminated material on site and found the site was suitable for the
proposed use. Since no contaminants are expected, the standard control measures described
below are deemed adequate for this site. Prior to construction UGL will confirm ground
conditions by:
On-site inspections during pre-construction site reviews to confirm desk-top study
predictions.
Potential Impacts
Approximately 200 square metres will be disturbed during construction of the proposal. The
foundation for the tilted mast and the trenches for the cables will result in about five cubic
metres of spoil. The trenches for the cables will be backfilled upon completion.
Excavation and trenching activities may result in erosion if appropriate mitigation measures are
not in place. Soil erosion has the potential to destabilise landforms and deposit sediments in
drainage systems and waterways. Sediment deposition and fine particles in suspension within
waterways have direct impact on water quality and aquatic life.
Given the site characteristics and the scope and size of the proposed work, it is anticipated that
erosion and sediment risks are minimal and can be effectively managed through the
implementation of standard measures as outlined in the Landcom/Department of Housing
Managing Urban Stormwater, Soils and Construction Guidelines (the Blue Book) (Landcom
2004).
No operational impacts are expected.
Page 31 of 72

Control Measures
Site specific Erosion and Sediment Control measures will be identified as part of ECM. The
proposed measures will be in accordance with the ‘Blue Book’ (Managing Urban Stormwater:
Soils and Construction 4 th Edn (Landcom, 2004), and will be implemented during the
construction phase. The measures will include, but not be limited to, those outlined below.
All spoil 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/ballast pads
Soil will be removed from public roads and other paved areas using dry street sweepers or
other measures
Disturbed areas will be reinstated, if required
During maintenance activities, any spills will be attended to and treated in an appropriate
and timely fashion in accordance with TfNSW procedures.
4.2 Water Quality and Hydrology
Existing Situation
The nearest waterway, Stanwell Creek, is about 116 metres southwest of the Location 2 and
flows directly into the Tasman Sea. The suburban stormwater system is situated along the main
roads (i.e. Lawrence Hargrave Road) however there are none within close distance to the
proposed site. The groundwater depth is not known and no data is available, however due to
the topography and elevation of the proposed site, it unlikely that groundwater will be
encountered during construction.
According to Wollongong Council, 1 in 100 year (ARI) flood mapping indicates the site is not
within a flood prone area.
Page 32 of 72

Possible Risks
There is a risk that the local underground water table may be reached and groundwater may be
encountered during pile boring activities. While this is not expected to occur at this site, it
remains the major risk in respect of water quality and hydrology. The CEMP, ECM and Water
Management Plan will contain procedures to manage this risk if it eventuates.
Potential Impacts
In addition to sediment rich runoff, the following wastewater types can be generated by
construction activities:
Liquid waste from non-destructive excavation;
Water from spills;
Sewage from the site facilities; and
Water collected in trenches and the pit.
Without appropriate safeguards, contaminants may reach nearby drains and discharge into
local waterways. These contaminants may have the potential to harm aquatic life and affect the
quality of water downstream. However, the risk of such occurrence would be minimised through
implementation of measures provided in the control measures listed below.
Rain or groundwater may enter the excavations. If inappropriately managed, sediment-laden
water could be discharged into local water bodies and/or the nearby stormwater system.
No operational impacts are expected. The works will not affect the landform or the flow of water
in the area.
Control Measures
During construction water quality impacts will be minimised through a range of control measures
in addition to the erosion and sedimentation controls included in Section 4.1. The water quality
measures will include, but will not be limited to those outlined below.
A Water Management Plan will be prepared before construction begins to determine the
most appropriate method for water disposal should groundwater be encountered during pile
boring activities.
A geological engineer will be present during the boring of the pile and work will cease
immediately if groundwater is encountered. The water will be tested according to industry
standards to determine the presence of contaminants or other materials. This will determine
the most appropriate method of water disposal. If water is encountered, special construction
methodologies will be adopted to prevent a continuing flow of groundwater to the surface.
Ensure construction materials are not left in the vicinity of stormwater drains.
Trenches and excavations will be covered to prevent rainwater entering.
Page 33 of 72

Plant and equipment will be checked regularly for oil leaks.
Plant and equipment will not be refuelled on site.
Wash down areas will be located away from waterways and drainage lines.
Liquid waste generated during non-destructive excavation will be removed from the-site for
treatment and disposal.
4.3 Air Quality
Existing Situation
Wollongong City Council’s State of the Environment Annual Report 2011-2012 reported that the
regional air quality in Wollongong was largely ‘good’. Local air quality is influenced by domestic
and industrial emissions and prevailing weather conditions.
Potential Impacts
Local and regional air quality can be affected during construction by dust, construction vehicle
emissions and odour. Dust may be generated from the disturbance of soils or poorly maintained
stockpile areas, which can affect human health or property. Poorly maintained vehicles can
produce excess emissions.
The works will require energy to power vehicles (e.g. construction, delivery and staff vehicles)
and construction plant. The energy requirements will primarily be in the form of fuel (petrol and
diesel). Fuel use will emit greenhouse gases with about 2.3 to 2.7 kilograms of carbon dioxide
equivalent (CO 2 -e) per litre of fuel consumed (DEWHA 2008). In addition, indirect and third
party emissions will be generated as a result of energy used to produce materials (for example
steel and concrete) – which is known as ‘embodied energy’.
During operation, electricity will be required to power the facility, but the energy use will form
only a small contribution to TfNSW’s overall greenhouse gas emissions.
Control Measures
Air quality impacts throughout construction will be minimised through a range of control
measures which will include, but will not be limited to, those outlined below.
Plant and equipment will be maintained in accordance with manufacturers’ specifications.
Regular inspection of plant and equipment will be undertaken to ascertain that fitted
emission controls are operating efficiently.
Plant or machinery will not be left idling.
Stockpiles will be maintained and contained appropriately, which could include covering or
regular watering to minimise dust.
Trucks transporting spoil and other waste materials from site will be covered appropriately.
Page 34 of 72

Disturbed areas will be rehabilitated as soon as practicable.
4.4 Biodiversity
Existing Situation
Based on a search within a one kilometre buffer of the proposed site Location 1, there are
25 species of fauna, 8 species of flora, 11 migratory bird species and one endangered
ecological community listed as threatened under the Environment Protection and Biodiversity
Conservation Act 1999 (EPBC Act). Based on a search within a one kilometre buffer of the
proposed site Location 2, there are 20 species of fauna, 8 species of flora, 15 migratory bird
species and one endangered ecological community listed as threatened under the Environment
Protection and Biodiversity Conservation Act 1999 (EPBC Act). These species or their habitat
may occur in the search area (refer Appendix 3). Based on a search within a 10 kilometre buffer
of the proposed sites, there are recordings of 58 threatened fauna species, 41 threatened flora
species and 11 endangered ecological communities listed under the Threatened Species
Conservation Act 1995 (TSC Act) within the search area (refer Appendix 3).
The immediate area around the outdoor sites has been cleared previously. There are mature
trees surrounding the two locations. RailCorp's Illawarra Vegetation Mapping Map 5 - Loftus to
Port Kembla identified the threatened Sooty Owl approximately 400 metres from Location 2.
RailCorp Sensitive Site Register identified native vegetation associated with Nature Reserves
adjacent to the proposed locations. This has been identified as the Illawarra state conservation
area.
There are 90 species of noxious weeds identified in the Wollongong LGA. Weed control is
enforceable by Wollongong Council, as the local control authority under the Noxious Weeds Act
1993. RailCorp vegetation mapping also indicates that Lantana, Crofton, and Turkey Rhubarb
are found on the proposed site.
Potential Impacts
While there are several threatened species known to be present in the Wollongong LGA, the
site is in a disturbed area adjacent to the rail corridor.
Tree cutting or pruning is not required for this site, and all areas of new trenching are also
located within cleared grassy areas. No native vegetation will be removed however grass will be
cleared.
The works are not expected to impact on listed threatened species or EECs. The Sooty Owl has
been sighted approximately 400 metres from Location 2. No impacts on this species is expected
as a result of the proposed work. Although there is dense vegetation surrounding the sites, the
locations are within the railway corridor in an area previously disturbed, therefore it is unlikely
that threatened fauna species will be present in the area.
Page 35 of 72

As such, the proposed works will not affect, threaten or have a significant impact on ecological
communities, plants or animals listed under the EPBC Act and/or TSC Act. Referral to the
Commonwealth Minister for Sustainability, Environment, Water, Population and Communities
for further consideration or approval in relation to potential flora and fauna impacts associated
with the works is not considered necessary. Similarly, the preparation of a Species Impact
Statement under NSW legislation to further consider the impacts of the proposal on threatened
plants or animals is not considered necessary.
Excavation work has the potential to affect nearby trees if roots are damaged during excavation
or equipment collides with trees. Location 1 is about seven metres away from the nearest trees
and Location 2 is about five metres away from the nearest trees which should be a sufficient
distance to avoid adverse impacts as excavation works are not required for this site.
Once soil has been disturbed there is the potential for the spread of weeds. Noxious weeds are
known to occur in the Stanwell Park area.
With regard to fauna, the work will not remove native vegetation or other features considered as
potential habitat for fauna (threatened or otherwise). Animals could potentially fall into an open
trench and become trapped or injured. Trapped animals could be accidentally entombed during
the backfilling of trenches.
No operational impacts are expected.
Control Measures
Impacts on flora and fauna throughout construction will be minimised through a range of control
measures which will include, but will not be limited to, those outlined below.
If threatened flora or fauna species are identified on site, work will stop immediately. A
spotter/catcher or botanist will be engaged to survey the site, in conjunction with TfNSW’s
Environmental Officer, and advise on species management.
No native vegetation will be removed.
Root cutting will be avoided.
Measures will be implemented to stop the spread of weeds. Appropriate management and
disposal of noxious weeds will be undertaken in consultation with Wollongong Council, if
required.
The work site will be inspected for trapped or injured fauna at the start of each day.
Trenches/excavations will be covered at the end of each day and inspected before they are
backfilled to ensure that no fauna species are harmed.

4.5 Noise and Vibration
Existing Situation
The adjacent railway line and traffic are the major sources of noise in the area.
The closest receivers to Location 1 are residents on Railway Crescent approximately 220
meters east. There are no schools, child care centres, hospitals, churches or churches within
500 metres of the proposed site (refer Section 1.3 for more information). The closest receiver
for Location 2 is the same resident as Location 1, approximately 420 metres east of Location 2.
Construction Noise
The Interim Construction Noise Guideline (ICNG) (DECC 2009) defines noise management
levels (measured in decibels) for residential receivers and other types of receivers including
commercial and industrial premises, places of worship and schools.
The ICNG states:
Where the predicted or measured L Aeq, 15 min is greater than the noise affected level, the
proponent should apply all feasible and reasonable work practices to meet the noise
affected level
The proponent should also inform all potentially affected residents of the nature of works to
be carried out, the expected noise levels and duration and contact details
For works above the highly affected noise criteria, respite periods may be required, and for
works outside standard hours there needs to be a strong justification and negotiation with
the community (DECC 2009).
Noise associated with the proposal is likely to be generated by construction trucks, machinery
and, in particular, boring activities required to establish the foundations for the mast. These
activities will be of a short duration.
Construction is expected to take six weeks and the majority of the work is expected to be
undertaken during standard working hours. Installation of the leaky feeder and cable will require
scheduled track possession (out of hours work from 6:00am Saturday 6 July 2013 to 6:00 pm
Sunday 7 July 2013). The key noise-generating activity, the pile boring, is expected to be
undertaken during one day during standard working hours.
Given this, background noise monitoring and the establishment of noise management levels for
residential receivers is not proposed. Nevertheless, a qualitative construction noise assessment
has been undertaken (refer Table 2).
In addition, the ICNG prescribes a highly noise affected criteria of 75 dBA L Aeq, 15min, which is the
point at which there may be strong community reaction to noise. Given the offset distance, it is
unlikely that sensitive receivers will experience a noise level above the highly affected level of
75 dBA L Aeq, 15min during the noisiest works.

Operational Noise and Vibration
Due to the nature of the operational activities on the site no operational impacts relating to noise
and vibration are expected.
Control Measures
Construction works will adopt Best Management Practice (BMP) and Best Available Technology
Economically Achievable (BATEA) practices as described in the Interim Construction Noise
Guideline (ICNG) (DECC 2009) and be carried out in accordance with TfNSW’s Construction
Noise Strategy.
Control measures to minimise noise and vibration impacts will include, but will not be limited to,
those outlined below.
Maximise the offset distance between noise plant items and sensitive receivers
Orient plant and equipment away from sensitive receivers
Avoid the simultaneous operation of two or more noise plant items in close vicinity and
adjacent to sensitive receivers
Carry out loading and unloading away from sensitive receivers
Where necessary, use structures to shield sensitive receivers from noise sources
Provide periods of respite if high noise generating activities occur for extended periods.
In addition, the community will be notified of the works and their duration and provided with
contact details before work begins. Any noise complaints received will be addressed by the
Project Manager as soon as possible.
4.6 Heritage
Existing Situation
A search for non-Aboriginal heritage items was completed by consulting the following
databases: Wollongong LEP, State Heritage Register, State Heritage Inventory, Australian
Heritage Database, (including Commonwealth Register of the National Estate), World Heritage
Sites and RailCorp’s Section 170 Heritage and Conservation Register.
The following heritage items are located in the vicinity of the proposal:
The Stanwell Park Coastal Conservation Area is on the non-statutory Register of the
National Estate as an indicative place and surrounds both locations.
Stanwell Park Rail Bridge (Viaduct) is also in the Register of the National Estate as an
indicative place, as well as listed in the RailCorp s.170 Heritage Register, State Heritage
Register and Wollongong LEP, and is about 70 metres west from Location 2.
Page 40 of 72

A search for known items of Aboriginal heritage value was undertaken for the proposed site,
(with a 200 metre buffer) using OEH’s Aboriginal Heritage Information Management System
(AHIMS). No Aboriginal sites or places were found at the location or its surrounds (refer
Appendix 3).
Potential Impacts
All work will be undertaken within the rail corridor and the proposed work will be undertaken
away from the heritage items listed above and outside the boundaries of heritage items. No
permits or approvals are required. As such, the works are unlikely to have an impact on known
items or places of non-Aboriginal heritage value.
The construction works will not impact known items of Aboriginal heritage significance.
The potential to uncover unidentified Aboriginal heritage items is low. The site is in an area that
has been disturbed previously. However, there is some potential for previously unidentified
items to be uncovered during construction.
Control Measures
Impact on heritage throughout construction will be minimised through a range of control
measures, which will include, but will not be limited to, those outlined below.
If a non-Aboriginal historical relic is discovered, all work likely to affect it will cease and the
Project Manager will be contacted. TfNSW staff and the Office of Environment and Heritage
(OEH) will be notified as required. An investigation will be undertaken by a suitably qualified
archaeologist to identify suitable measures to reduce the impact on the relic discovered
before work resumes.
Should Aboriginal heritage items be uncovered, all work in the vicinity will cease and the
Project Manager and TfNSW staff will be notified immediately. The OEH will be notified in
accordance with the National Parks and Wildlife Act 1974. The local Aboriginal Land
Council will be notified and an assessment by an archaeologist will be arranged to
determine the significance of the objects and other requirements before work resumes.
4.7 Waste
Overview
TfNSW is required to manage waste in accordance with the Waste Avoidance and Resource
Recovery Act 2001 (WARR Act). The waste hierarchy (Avoid, Reuse, Recycle, Energy
Recovery and Disposal) should be followed for all projects. No current waste has been identified
on site.
Potential Impacts
The main waste streams that may be generated during construction include:
Spoil from excavation;
Page 41 of 72

Concrete
Asphalt;
Vegetation;
Packaging;
General litter including glass, plastic, metal and paper waste;
Wiring; and
Wastewater from non-destructive excavation.
No operational impacts are expected.
Control Measures
A Waste Management Plan will be prepared as part of CEMP to detail waste types and
quantities as well as methods for segregation, handling, storing and disposal. Furthermore,
waste impacts will be minimised through a range of control measures, (consistent with the
WARR Act) which will include, but not be limited to, those outlined below.
All waste will be classified in accordance with the Waste Classification Guidelines (DECC
2009) and transported to a place that can lawfully accept the waste.
Material that may be classified as a hazardous waste will be managed appropriately and in
accordance with TfNSW procedures.
Packaging will be minimised, where possible and where the safety and delivery of services
is not compromised.
Wherever possible, suitable excavated spoil will be reused on site for backfilling,
landscaping and other purposes.
Spoil or waste material tracked onto roads will be swept up immediately.
Adequate numbers of bins and waste containers will be placed at the site. The site manager
will ensure bins are not overflowing and are appropriately covered.
Waste water generated by non-destructive excavation will be taken off site for treatment
and disposal.
All waste will be removed from the site when work is completed.
4.8 Contaminated Land
Existing Situation
An initial investigation has been carried out for potential land contamination. The investigation
included:
A site walk over and visual inspection for potential signs of land contamination;
Page 42 of 72

A search of OEH register of contaminated sites;
A search of RailCorp records; and
A review of all materials to be used at the site to establish their potential for land
contamination.
RailCorp does not have record or evidence that the site can be contaminated. There were no
contaminated sites near the vicinity of the proposed DBS site.
Hazardous materials will not be used during construction and operation and, therefore, the
proposed work will not result in new site contamination.
Potential Impact
Although not identified as part of the initial investigation, the limited desktop investigation cannot
exclude potential contamination as the result of unknown past activities, either on the site or in
the vicinity. There is a risk that contaminants could be encountered during the proposed work. If
encountered, contaminants may pose a risk to the health of workers and the environment in
general.
Control Measures
The risk of encountering unknown contaminants during excavation will be managed in
accordance with TfNSW procedures, the CEMP and land contamination legislation.
Control measures to manage contamination risks will include, but not be limited to, those
outlined below.
During excavation, site workers will look for signs of potential contamination such as the
presence of waste and/or other imported materials, odours, soil colouring, floating layers in
groundwater etc.
If any contamination is encountered, or suspected, the work will be immediately stoped and
the site fenced off. The site will be investigated and validated and work will only resume
after approval from HSE Manager is obtained. Contaminated soil will be segregated in a
special container before classification and disposal.
4.9 Hazardous Materials
Potential Impacts
Construction, operation and maintenance of the proposed facility will not require the use of
hazardous chemicals and/or materials.
If not properly used, chemicals may present a risk to the safety of workers and the environment
in general. Safe use of hazardous chemicals is regulated and subject to numerous standards,
including a need for a dangerous goods licence.
Control Measures
Page 43 of 72

If hazardous materials are required for any unforeseen reason, a hazardous waste
management plan would be prepared. The plan will detail terms applying to the purchase,
storage, use, handling and disposal of such materials.
The impact of hazardous materials will be minimised through a range of control measures
including, but not limited to, those outlined below.
Hazardous materials will be properly classified and managed in accordance with
requirements for their particular class.
An evaluation of alternative materials will be undertaken before use of chemicals is
approved.
Hazardous materials will be transported, stored and used in accordance with the
corresponding material safety data sheets which will be available on the site.
Hazardous materials will be stored in a locked and bundled area at the site; incompatible
chemicals will not be stored together.
No fuels will be stored on site. Refuelling will be undertaken at off-site facilities.
Adequate spill prevention, containment and response measures (e.g. drip trays) will be
provided on site if needed.
Construction personnel will be trained in spill containment and response procedures.
All storage and handling equipment on site will be maintained properly.
4.10 Visual Aesthetics and Urban Design
Existing Situation
The visual landscape surrounding the proposed site includes the South Coast Line and
associated overhead power lines. There is vegetation surrounding the corridor largely
associated with the Illawarra Conservation Area to the west.
Residential dwellings are about 220 metres east from Location 1 and about 420 metres east
from Location 2 on Railway Crescent.
Potential Impacts
During construction the visual environment will be temporarily altered through the presence of
temporary work buildings, plant and equipment.
While the site is operational, a new 10 metre high tilted mast will be introduced into the visual
environment. The 1.7 metre high cabinet and a small mast mounted on west end of portal will
be of little visual significance.
A photomontage of the new hinged mast and portal mounted mast is provided as a guide in
Figure 5 and Figure 6..
Page 44 of 72

Visually sensitive receivers in the vicinity of the site include residential receivers located
approximately 220 metres to the east of the Location 1 and approximately 420 metres east of
Location 2. There is dense vegetation providing screening for the residential receivers from both
locations. No residential receiver will have a direct view of the masts.
The potential visual impact of the proposal is considered to be low.
Figure 5
View of hinged mast at Location 1 looking southwest along the eastern
side of the rail corridor
Page 45 of 72

Figure 6
View of Location 2 facing the western end tunnel portal
Control Measures
Visual impact will be minimised through a range of control measures which will include, but will
not be limited to, those outlined below.
The work area shall be maintained in an orderly manner.
All temporary signage associated with the works must be appropriately displayed.
All work equipment and materials will be contained within the designated boundaries of the
work site.
All waste generated during the course of the works will be removed from the work areas as
soon as practicable or at the end of each work day and disposed of in accordance with the
measures identified for ‘Waste’.
On completion of work, all vehicles, materials and refuse relating to the works will be
removed and the site reinstated to the pre-work condition if not better.
4.11 Land Use
Existing Situation
The proposed sites are on land owned by TfNSW and zoned for the purposes of a railway under
the Wollongong LEP. The land where the new tilted mast and cabinets are to be situated and
Page 46 of 72

where trenching is required is not actively used for TfNSW activities (i.e. an access route or
storage area). The immediate neighbouring land uses are mainly bushland with some
residential dwellings to the west and southwest.
Potential Impacts
The proposal will not affect or alter the current use of the site or the immediate surrounding area
as a rail corridor. It will not have effects on the use of the neighbouring properties.
Control Measures
No specific control measures are required.
4.12 Socio-Economic Effects
Existing Situation
The proposed site is in the Wollongong LGA, which in the 2006 census had a population of
around 184,000. Coalcliff and Stanwell are mostly residential suburbs with small commercial
areas.
The railway line runs along the boundary of Stanwell Park through dense bushland.
Potential Impacts
Social and economic considerations typically focus on the effect on the local community as a
whole, and on local businesses. Amenity issues such as noise, visual impacts and traffic are
some of the key areas that can affect the community and are discussed in detail in sections 4.5,
4.10 and 4.14.
Construction is unlikely to have adverse effect on nearby businesses, as work will be within the
rail corridor. Noise impacts will be temporary (less than six weeks). There will be no traffic or
access changes for businesses or residents.
As some work may be undertaken during scheduled trackwork, some activity may occur on
weekends to minimise interruptions to train services as a result of the work.
The site will be appropriately fenced off during construction. In operation, the facility will be
fenced off and pose only a minimal risk to public safety.
There will be positive long term effects resulting from the proposal, as the new DTRS will
provide a more effective communication service and improve the safety of the rail network.
There may be minor short-term positive impacts for the surrounding area as a result of the need
for materials, transport, food, services and accommodation.
The DTRS project has a capital value of approximately $225 million and will generate over 100
jobs over the life of the project.
Page 47 of 72

Control Measures
In addition to the control measures proposed in the noise, traffic and visual sections, other
control measures are outlined below.
Nearby residents and businesses will be informed about the nature and timing of works.
Signage will notify the public about the works.
Appropriate fencing around the site will help maintain public safety during construction and
operation.
4.13 Electromagnetic Energy (EME)
Overview
Electromagnetic energy (EME) is the energy stored in an electromagnetic field. Radiofrequency
EME refers to the EME generated by radio waves. EME is a factor of everyday life and is
emitted by natural sources such as the sun and earth, and by man-made sources operating on
radio waves (e.g. TV and radio broadcasts), baby monitors, model planes, mobile phone base
stations and radio communications facilities.
The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has established a
radiation protection standard specifying limits for continuous exposure of the general public and
occupational workers to radio frequency emissions.
Potential Impacts
EME levels emitted by the proposal have been estimated at 1.5 metres above ground level at
various distances from the proposed antennas. It should be noted that the actual EME levels
will be significantly less than predicted due to path losses and the fact that the DBS
automatically minimises transmitter power to serve only established phone calls. The maximum
cumulative EME level at 1.5 metres above the ground for location 1 is estimated to be 0.015%
of the ARPANSA exposure limits. The maximum EME for location 2 is estimated to be 0.0083%
of the safe ARPANSA exposure limits. EME impacts are unlikely when the facility is operational.
The EME report is included at Appendix 4.
Control Measures
The various elements will be located in areas that are not accessible by the public. However,
the following control measures will also minimise health and safety risks.
Appropriate signage will be placed around the site to warn people of the potential hazards.
All people required to work around occupationally hazardous radio frequencies will
undergo RadHaz training.
Page 48 of 72

4.14 Traffic and Access
Existing Situation
Access to the both locations will be via an existing dirt road and TfNSW locked double access
gate at the Stanwell Park Station 500 metres north-east from the Location 1. The land is
suitable for vehicle use during the construction period and there is no need to develop a new
access track or road. It is estimated that TfNSW staff and contractors currently use the gate and
access track around 14-20 times a year.
Potential Impacts
During construction, there will be an increased number of vehicles using the local streets;
however, the anticipated increase in the volume of traffic is relatively small (about four to six
truck movements per day).
As works are to take place in the rail corridor access changes to local roads or access to
driveways are not expected.
Vehicular traffic in the rail corridor will be limited to concrete and delivery trucks for the DBS
cabinets and the hinged mast sections and trucks with pile boring or trenching equipment.
These trucks are not large enough to prevent access via the access gate.
There will be some traffic movement associated with vehicles that will need to access the site
for maintenance requirements. However, the volume of traffic will be very small and will not
adversely impact on the surrounding road network. It is proposed that the hinged mast and
antennas be accessed via an elevated work platform or through the use of a ladder and dual
lard system.
Control Measures
Impacts associated with traffic and access will be minimised through a range of control
measures, which will include, but will not be limited to those outlined below.
A Traffic Management Plan will be developed for the site
Dilapidation survey to be completed prior to construction commencing
All pavement and road surfaces damaged during construction will be restored when work is
finished
The Traffic Management Plan will ensure compliance with Australian Standard AS1742.3-
2002 Manual of uniform traffic control devices – traffic control devices on roads.
4.15 Utilities and Services
Existing Situation
There is a number of existing services such as electricity, fibre and sewer close to the proposed
site. There are overhead power lines within the area of proposed work and a site specific Safe
Page 49 of 72

Work Method Statement (SWMS) will describe the hazards and control measures associated
with working in the vicinity of high voltage power lines.
Potential Impacts
The facility will be connected to the existing electricity supply and fibre network and does not
require connections to water or gas.
There are a number of public utilities near the site and there is the potential for some known or
unknown services to be impacted during excavation or relocation/connections. Depending on
the service, outages or interruptions could affect nearby properties or the rail network.
Control Measures
• Ensure that a Dial Before You Dig call and a services search are undertaken to identify
services.
• Consult with public utility providers to minimise impacts during utility relocations or
readjustments.
4.16 Light spill
Construction lighting will be required to enable the proposed work to install the cable and feeder
connections within the tunnel during the scheduled track possession. Light spill impacts are not
anticipated as residential receivers are located over 200 metres from both locations. There will
be no new permanent lighting proposed.
4.17 Demand on Resources
Construction materials are readily available and will be sourced from local contractors where
possible.
4.18 Cumulative Environmental Effects
Cumulative impacts often result when several different construction projects are scheduled for
similar times and locations.
A search of the Department of Planning and Infrastructure’s Major Projects register was
undertaken and no major projects were identified in the vicinity of the proposed site. A search of
Wollongong Council’s major development applications register and the TfNSW projects website
did not identify large projects nearby that might be constructed at a similar time.
There is also a risk of cumulative impacts if unscheduled work, e.g. emergency work by other
utilities or developers, is required. Such situations will be monitored and addressed by the
Project Manager.
The Stanwell Park Tunnel DBS site is one of a large number of radio communications facilities
being installed across the electrified network as part of the DTRS project. In terms of localised
Page 50 of 72

cumulative construction impacts, the nearest construction for the DTRS project will be at the
Tree Tops DBS site, which is more than 400 metres south of the proposed site. Even if both
facilities were constructed simultaneously, it is not likely cumulative noise or local traffic impacts
will result.
Overall this work, as part of the DTRS project, will result in significant benefits by providing a
more effective communications systems for the TfNSW network. The GSM-R system is in use
around the world and allows for continuous communications coverage, the capacity to make
simultaneous calls and greatly improved emergency calling capabilities. Once active, the DTRS
will provide a more effective communications system that will assist in the safe and efficient
operation of TfNSW’s electrified rail network.
Control Measures
• Other major development or works planned in the vicinity of the site will be investigated
before construction begins.
• Consultation with Wollongong City Council and other relevant stakeholders regarding other
developments will be undertaken on an ongoing basis.

4.20 Summary of Control Measures
Landforms, Geology and Soils
All spoil will be transferred directly to skip bins or stockpiled appropriately
Appropriate stockpiling of materials will take place away from drainage lines,
Page 55 of 72

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/ballast pads
Soil will be removed from public roads and other paved areas using dry street
sweepers or other measures
Disturbed areas will be reinstated, if required
During maintenance activities, any spills will be attended to and treated in an
appropriate and timely fashion in accordance with TfNSW procedures.
Water Quality and Hydrology
A Water Management Plan will be prepared before construction begins to determine
the most appropriate method for water disposal should groundwater be encountered
during pile boring activities.
A geological engineer will be present during the boring of the pile and work will cease
immediately if groundwater is encountered. The water will be tested according to
industry standards to determine the presence of contaminants or other materials. This
will determine the most appropriate method of water disposal. If water is encountered,
special construction methodologies will be adopted to prevent a continuing flow of
groundwater to the surface.
Ensure construction materials are not left in the vicinity of stormwater drains.
Trenches and excavations will be covered to prevent rainwater entering.
Plant and equipment will be checked regularly for oil leaks.
Plant and equipment will not be refuelled on site.
Wash down areas will be located away from waterways and drainage lines.
Liquid waste generated during non-destructive excavation will be removed from thesite
for treatment and disposal.
Air Quality
Plant and equipment will be maintained in accordance with manufacturers’
Page 56 of 72

specifications.
Regular inspection of plant and equipment will be undertaken to ascertain that fitted
emission controls are operating efficiently.
Plant or machinery will not be left idling.
Stockpiles will be maintained and contained appropriately, which could include
covering or regular watering to minimise dust.
Trucks transporting spoil and other waste materials from site will be covered
appropriately.
Disturbed areas will be rehabilitated as soon as practicable.
Biodiversity
If threatened flora or fauna species are identified on site, work will stop immediately. A
spotter/catcher or botanist will be engaged to survey the site, in conjunction with
TfNSW’s Environmental Officer, and advise on species management.
No native vegetation will be removed.
Root cutting will be avoided.
Measures will be implemented to stop the spread of weeds. Appropriate management
and disposal of noxious weeds will be undertaken in consultation with Wollongong
Council, if required.
The work site will be inspected for trapped or injured fauna at the start of each day.
Trenches/excavations will be covered at the end of each day and inspected before
they are backfilled to ensure that no fauna species are harmed.
Noise and Vibration
Maximise the offset distance between noise plant items and sensitive receivers
Orient plant and equipment away from sensitive receivers
Avoid the simultaneous operation of two or more noise plant items in close vicinity and
adjacent to sensitive receivers
Carry out loading and unloading away from sensitive receivers
Where necessary, use structures to shield sensitive receivers from noise sources
Provide periods of respite if high noise generating activities occur for extended
Page 57 of 72

periods.
Heritage
If a non-Aboriginal historical relic is discovered, all work likely to affect it will cease and
the Project Manager will be contacted. TfNSW staff and the Office of Environment and
Heritage (OEH) will be notified as required. An investigation will be undertaken by a
suitably qualified archaeologist to identify suitable measures to reduce the impact on
the relic discovered before work resumes.
Should Aboriginal heritage items be uncovered, all work in the vicinity will cease and
the Project Manager and TfNSW staff will be notified immediately. The OEH will be
notified in accordance with the National Parks and Wildlife Act 1974. The local
Aboriginal Land Council will be notified and an assessment by an archaeologist will be
arranged to determine the significance of the objects and other requirements before
work resumes.
Waste
All waste will be classified in accordance with the Waste Classification Guidelines
(DECC 2009) and transported to a place that can lawfully accept the waste.
Material that may be classified as a hazardous waste will be managed appropriately
and in accordance with TfNSW procedures.
Packaging will be minimised, where possible and where the safety and delivery of
services is not compromised.
Wherever possible, suitable excavated spoil will be reused on site for backfilling,
landscaping and other purposes.
Spoil or waste material tracked onto roads will be swept up immediately.
Adequate numbers of bins and waste containers will be placed at the site. The site
manager will ensure bins are not overflowing and are appropriately covered.
Waste water generated by non-destructive excavation will be taken off site for
treatment and disposal.
All waste will be removed from the site when work is completed.
Contaminated Land
During excavation, site workers will look for signs of potential contamination such as
Page 58 of 72

the presence of waste and/or other imported materials, odours, soil colouring, floating
layers in groundwater etc.
If any contamination is encountered, or suspected, the work will be immediately stoped
and the site fenced off. The site will be investigated and validated and work will only
resume after approval from HSE Manager is obtained. Contaminated soil will be
segregated in a special container before classification and disposal.
Hazardous Materials
Hazardous materials will be properly classified and managed in accordance with
requirements for their particular class.
An evaluation of alternative materials will be undertaken before use of chemicals is
approved.
Hazardous materials will be transported, stored and used in accordance with the

Appendix 1: Principles from the Telecommunications
Facilities Guidelines
Principle 1: A telecommunications facility is to be designed and sited to minimise visual
impact.
Principle
(a) As far as practical, a telecommunications
facility that is to be mounted on an existing
building or structure should be integrated with
the design and appearance of the building or
structure.
(b) The visual impact of telecommunications
facilities should be minimised, visual clutter is
to be reduced particularly on tops of buildings,
and their physical dimensions (including
support mounts) should be sympathetic to the
scale and height of the building to which it is to
be attached, and sympathetic to adjacent
buildings.
(c) Where telecommunications facilities
protrude from a building or structure and are
predominantly backgrounded against the sky,
the facility and their support mounts should be
either the same as the prevailing colour of the
host building or structure, or a neutral colour
such as grey should be used.
(d) Ancillary facilities associated with the
telecommunications facility should be
screened or housed, using the same colour as
the prevailing background to reduce its
visibility, including the use of existing
vegetation where available, or new
landscaping where possible and practical.
Proposal
Location 2 involves the installation of a Yagi
antenna to the west portal of the Stanwell
Park Tunnel and will be integrated with the
design and appearance of the tunnel
structure.
The design and site selection process aimed
to minimise visual impact. This has been
achieved by selecting a location inside the rail
corridor where there is already a level of
disturbance, the presence of vertical
structures as well as trees along the edge of
the rail corridor. The selection of a tilted mast
and antenna mounting system that is
unobtrusive with minimal visual bulk will also
minimise visual impact.
Location 2 involves the installation of a Yagi
antenna to the west portal of the Stanwell
Park Tunnel and will be designed to match as
best as possible the appearance of the tunnel
structure in terms of colour.
The outdoor cabinets will be adjacent to the
base of the hinged mast. The cabinets will be
less than two metres high.

Principle
(e) A telecommunications facility should be
located and designed to respond appropriately
to its bushland landscape setting.
(f) A telecommunications facility located on, or
adjacent to, a State or local heritage item or
within a heritage conservation area, should be
sited and designed with external colours,
finishes and scale sympathetic to those of the
heritage item or conservation area.
(g) A telecommunications facility should be
located so as to minimise or avoid the
obstruction of a significant view of a heritage
item or place, a landmark, a streetscape, vista
or a panorama, whether viewed from public or
private land.
(h) The relevant local government authority
must be consulted where the pruning, lopping,
or removal of tree or other vegetation would
contravene a Tree Preservation Order
applying to the land or where a permit or
development consent is required.
(i) A telecommunications facility that is no
longer required is to be removed and the site
restored, to a condition that is similar to its
condition before the facility was constructed.
(j) The siting and design of
telecommunications facilities should be in
accordance with relevant Industry Design
Guides.
Proposal
The proposed site will be located and
designed to respond appropriately to its
bushland landscape setting.
The visual elements of the proposal are not on
or within a heritage item. The site is within the
Stanwell Park Coastal Conservation Area
which is on the non-statutory Register of the
National Estate as an indicative place. The
BTS design is sympathetic in design and scale
to the conservation area, as far as practical.
The proposed facility will not block or
significantly obstruct views of heritage items or
other landmarks of state significance.
The proposed tilted mast is less than 500
millimetres wide at the top and will not have a
headframe supporting the antennas. The tilted
mast will not represent a dominant structure in
the view lines of people occupying the
residential properties in the surrounding area.
No native vegetation will be removed.
Should the facility ever become redundant, the
various elements will be decommissioned and
removed. Following removal, the land will be
restored as close as practicable to its
condition before work began.
The proposed design has been completed
using “best industry practice” and complies
with the relevant standards regarding
structural engineering, EME and construction
procedures.

Principle 2: Telecommunications facilities should be co-located wherever practical.
Principle
(a) Telecommunications lines are to be
located, as far as practical, underground or
within an existing underground conduit or
duct.
(b) Overhead lines, antennas and ancillary
telecommunications facilities should, where
practical, be co-located or attached to existing
structures such as buildings, public utility
structures, poles, towers or other radio
communications equipment to minimise the
proliferation of telecommunication facilities
and unnecessary clutter.
(c) Towers may be extended for the purposes
of co-location.
(d) The extension of an existing tower must
be considered as a practical co-location
solution prior to building new towers.
(e) If a facility is proposed not to be colocated
the proponent must demonstrate that
co-location is not practicable.
(f) If the development is for a co-location
purpose, then new telecommunications facility
must be designed, installed and operated so
that the resultant cumulative levels of radio
frequency emissions of the co-located
telecommunications facilities are within the
maximum human exposure levels set out in
the Radiation Protection Standard.
Proposal
The fibre connections for the DTRS network
will be in existing conduits or in new
underground conduits wherever feasible or
possible.
Co-location on other communications towers
has been considered. No other towers were
deemed appropriate or in a location to
provide sufficient network coverage, as such
a new tilted mast is proposed (refer Section
3.5).
The proposal does not involve the use of an
existing tower. The extension of existing
towers in the area was considered and
deemed unsuitable.
The proposal does not involve the use of an
existing tower; however the extension of
existing towers in the area was considered
and deemed unsuitable (refer Section 3.5).
There are no suitable communications
towers in the target coverage area that would
satisfy the coverage objectives as well as the
network requirements of the DTRS project.
Co-location is not proposed.

Principle 3: Health standards for exposure to radio emissions will be met.
Principle
(a) A telecommunications facility must be
designed, installed and operated so that the
maximum human exposure levels to
radiofrequency emissions comply with
Radiation Protection Standard.
(b) An EME Environmental Report shall be
produced by the proponent of development
to which the Mobile Phone Network Code
applies in terms of design, siting of facilities
and notifications.
The Report is to be in the format required by
the Australian Radiation Protection Nuclear
Safety Agency (ARPANSA). It is to show the
predicted levels of electromagnetic energy
surrounding the development comply with
the safety limits imposed by the Australian
Communications and Media Authority and
the Electromagnetic Radiation Standard, and
demonstrate compliance with the Mobile
Phone Networks Code.
Proposal
The proposed facility will comply with the
ARPANSA standard in relation to human
exposure to EME. An EME report has been
completed and is found at Appendix 4.
This report demonstrates compliance with the
ARPANSA standard for the operation of a
radio communications facility in Australia.
The proposal is not for a mobile phone
network and is not subject to the Code for the
Development of Mobile Phone Network
Infrastructure commonly known as the ACIF
Code.
An EME report has been completed and is
found at Appendix 4.
Principle 4: Minimise disturbance and risk, and maximise compliance
Principle
(a) The siting and height of
telecommunications facility must comply with
relevant site and height requirements specified
by the Civil Aviation Regulations 1988 and the
Airports (Protection of Airspace) Regulations
1996 of the Commonwealth. It must not
penetrate obstacle limitation surface shown on
relevant Obstacle Limitation Surface Plan that
has been prepared by the operator of an
Proposal
The provisions of the Civil Aviation
Regulations 1988 and the Airports (Protection
of Airspace) Regulations 1996 were
considered during the design and siting
process. There is no need for the installation
of a warning light or aircraft navigation light, as
the proposal does not penetrate the Obstacle
Limitation Surface.

Proposal
aerodrome or airport operating within 30
kilometres of the proposed development and
reported to the Civil Aviation Safety Authority
Australia.
(b) The telecommunications facility is not to
cause adverse radio frequency interference
with airport, port or Commonwealth Defence
navigational or communications equipment,
including the Morundah Communication
Facility, Riverina.
(c) The telecommunications facility and
ancillary facilities are to be carried out in
accordance with the applicable specifications
of the manufacturers for the installation of
such equipment.
(d) The telecommunications facility is not to
affect the structural integrity of building on
which it is erected.
(e) The telecommunications facility is to be
erected wholly within the boundaries of a
property where the landowner has agreed to
the facility being located on the land.
(f) The carrying out of construction of the
telecommunications facilities must be in
accordance with all relevant regulations of the
Blue Book – ‘Managing Urban Storm water:
Soils and Construction’ (DECC 2008), or its
replacement.
(g) Obstruction or risks to pedestrians or
vehicles caused by the location of the facility,
construction activity or materials used in
construction are to be mitigated.
TfNSW will operate the radio facility with its
own spectrum and the facility will not cause
interference with other networks. All radio
transmitters will use the frequency assigned to
TfNSW for the exclusive use of TfNSW.
The installation and operation of the radio
equipment and antennas will be carried out in
accordance with the manufacturers’
specifications.
Location 2 involves the minimally invasive
attachment of a Yagi antenna to the west end
portal of the Stanwell Park Tunnel, and will not
affect it’s structurally integrity pre- or postconstruction.
The proposed facility will be inside the rail
corridor that is owned and used by TfNSW.
TfNSW is the proponent of the network and
agrees to the use of the land for the proposed
radio equipment.
The activities associated with construction and
installation will be done in accordance with
sediment controls, erosion controls,
stormwater controls and other controls
outlined in the Blue Book (refer Section 4.1).
Construction activities will take place in the rail
corridor and changes to traffic and access are
not expected.

Principle
Proposal
accordance with an approved Traffic
Management Plan
There will be no risks to traffic or pedestrians
during the operation of the proposal.
(h) Where practical, work is to be carried out
during times that cause minimum disruption to
adjoining properties and public access. Hours
of work are to be restricted to between 7:00am
to 6:00pm, Mondays to Fridays, 8:00am to
1:00pm Saturdays, with no work on Sundays
and public holidays.
(i) Traffic control measures are to be taken
during construction in accordance with
Australian Standard AS1742.3-2002 Manual of
uniform traffic control devices – Traffic control
devices on roads.
(j) Open trenching should be guarded in
accordance with Australian Standard Section
93.080 – Road Engineering AS1165 – 1982 –
Traffic hazard warning lamps.
(k) Disturbance to flora and fauna should be
minimised and the land is to be restored to a
condition that is similar to its condition before
the work was carried out.
(l) The likelihood of impacting on threatened
species and communities should be identified
in consultation with relevant state or local
government authorities and disturbance to
identified species and communities avoided
wherever possible.
Out of hours work will occur from 6:00am
Saturday 6 July 2013 to 6:00 pm Sunday 7
July 2013 is required for leaky feeder and
cable installation through the tunnel.
All other works associated with the
development and installation of the DBS site
will occur between 7:00am to 6:00pm,
Mondays to Fridays and 8:00am to 1:00pm
Saturdays.
A Traffic Management Plan will be developed
and implemented during construction and
installation activities. The procedures and
mitigation measures in the plan will ensure
compliance with Australian Standard
AS1742.3-2002 Manual of uniform traffic
control devices – Traffic control devices on
roads (Refer Section 4.14).
There will be no open trenches outside the rail
corridor and all trenches will be covered or
filled so that they are not open overnight.
No native vegetation will be removed. The
land will be reinstated to its original condition
prior to construction.
The proposed activities do not require the
removal of native vegetation. A search of
threatened species has been completed (refer
Appendix 3) and there is not expected to be
significant impact on threatened species.
Page 68 of 72

Principle
(m) The likelihood of harming an Aboriginal
Place and / or Aboriginal object should be
identified. Approvals from the Office of
Environment & Heritage (OEH) must be
obtained where impact is likely, or Aboriginal
objects are found.
(n) Street furniture, paving or other existing
facilities removed or damaged during
construction should be reinstated (at the
telecommunications carrier’s expense) to at
least the same condition as that which existed
prior to the telecommunications facility being
installed.
Proposal
A search of the AHIMS has been completed
and there are no known items or places of
archaeological significance on the site or in
the immediate surrounding area (refer
Appendix 3).
If suspicious items or objects are found during
excavation, work will cease immediately and
the OEH will be consulted and works will not
re-commence until OEH have granted their
consent.
Any street furniture, paving or other existing
facilities affected by the construction works will
be reinstated at the end of construction to at
least the same condition they were in before
work began.
