Executive Summary
Need for the Proposal
RailCorp 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 RailCorp
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 (WSCOI). 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 for approximately 1455 kilometres of the RailCorp
electrified network as well as in 66 tunnels covering approximately 70 kilometres and has an
expected design life of at least 15 years. UGL Infrastructure has been contracted to design and
construct the DTRS
Proposal Description
The Como base transceiver station (BTS) will be installed on a mild slope in an open, grassy
area within the rail corridor as part of the DTRS project. The new BTS will be situated
approximately 12.6 metres east of the south-bound track and 800 metres north of Como railway
station. It will provide communications coverage for a 4.65 kilometre section of track for trains
travelling between Oatley and Jannali on the Illawarra Line. Construction will take approximately
six weeks.
The proposal will involve the following.
• a 25 metre high monopole, with a 1.5 metre high lightning rod at the top;
• two Argus panel antennas mounted on the monopole;
• power and BTS cabinets located on a slab two metres from the monopole;
• conduit feeder cables to connect to the existing power and fibre supply, installed at a depth
of at least 600 millimetres;
• new isolating transformer, meter cabinet and distribution board as part of the power
connections.
• other associated and necessary activities to ensure the proper functioning of the RailCorp
radio communications facility including earthing, safe access, signage and bollards for
vehicle protection.

Approval Process
The proposal is being assessed under Part 5 of the Environmental Planning and Assessment
Act 1979 (EP&A Act) which requires RailCorp 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 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 impacts resulting from construction and operation of the facility have been assessed in this
REF. This REF concludes that, subject to the implementation of mitigation measures, potential
environmental impacts can be controlled and reduced to acceptable levels, therefore work will
not compromising the health, diversity and productivity of the environment for the benefit of
future generations.
The main environmental issues relate to construction impacts such as erosion and
sedimentation risks as well as short-term traffic, air quality and noise impacts for nearby
receivers. The proposed site is in a recreation area, close to the Como Marina. The heritagelisted
Como rail bridge has been converted to a pedestrian/bike path and is close to the site.
However, given that the works are to take place in the rail corridor and are of a temporary
nature (i.e. less than six weeks), impacts to surrounding land uses are expected to be minor.
In the long term, a new monopole will be introduced into the visual landscape. The antennas
and monopole will not be bulky and will be partially screened by the vegetation along the rail
corridor; however the top of the monopole may be visible to residents and recreational visitors.
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
The proposed control measures described at the end of each environmental impact section in
this REF will be incorporated into a Construction Environmental Management Plan (CEMP).
The following sub plans are proposed in the REF and will be prepared concurrently with CEMP:
• Erosion and Sedimentation Control Plan; and
• Traffic Management Plan.
The CEMP and sub plans will be reviewed by RailCorp before construction begins.

1 Introduction
1.1 Background to the Project
RailCorp 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 RailCorp
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 (WSCOI).
The primary objectives of the DTRS project are to:
• provide continuous radio coverage 100% radio of RailCorp’s electric network;
• replace and improve on the current RailCorp MetroNet communications system;
• provide a technology platform for future development of an automatic train protection
system (ATP); and
• 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 1455 kilometres of the
RailCorp electric network as well as in 66 tunnels covering approximately 70 kilometres 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;
• approximately 255 base transceiver stations (BTS) as well as other base stations in tunnels;
• approximately 65 dispatcher terminal units; and
• capability to provide staff with handheld terminals.
The DTRS will provide continuous coverage along the entire RailCorp electrified network for ontrain
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 Como site
The proposed base transceiver station (BTS) at Como is part of the DTRS that is being
developed along RailCorp’s electrified train lines. The proposal at Como is for a new BTS,
which aims to provide coverage along a 4.65 kilometre section of track for trains travelling
between Oatley and Jannali on the Illawarra Line.
The Como BTS is one of around 250 radio facilities which will provide enhanced, efficient and
reliable communication systems for the RailCorp’s electrified network.

The proposed BTS site is on the eastern side of the rail corridor approximately 12.6 metres from
the south-bound track, on the Illawarra line (Figure 2). The proposed facility will be on a mild
slope in an open, grassy area within the rail corridor (refer Figure 3). There are trees in the
vicinity and existing fences, power cabinets and overhead wires. A RailCorp building is
approximately 40 metres to the south. Como railway station is approximately 800 metres south
of the proposed site.

The heritage-listed Como rail bridge that extends across the Georges River is to the north of the
proposed site and has been converted to a pedestrian and bike path, connecting Oatley to
Como.
The site within the Sutherland Local Government Area (LGA) and the proposed work will be
undertaken on land in the Zone 21 – Railway area.
Land around the site is used for the purposes listed below.
• To the north is the rail corridor, the heritage-listed Como rail bridge (which has now been
converted to a pedestrian/bike path) and the Georges River.
• To the east is the Como Marina and Scylla Bay.
• To the south-east the railway plateau, covered with a bank of trees, falls steeply towards
the pedestrian/bike path, the Como Marina and associated businesses, the Como Pleasure
Grounds and Como swimming complex.
• To the south is a substation, Scylla Bay Reserve and a number of residential dwellings
along Cremona Road. The nearest residential receivers are approximately 240 metres from
the proposed site.
• To the south-west are residential dwellings on Como Parade and Central Parade, the
nearest residential receivers are approximately 100 metres away.
• To the west are the rail corridor and the Georges River.
Access to the site is off Cremona Road through the existing railway gate which is opposite the
entrance to Como Marina. The gate is suitable for construction vehicle access.
The climate in the area is similar to other parts of the Sydney Basin. The area experiences
extremes of climate, having a peak monthly precipitation of 114.2 millimetres in February and
the lowest rainfall in September with an average of 52.5 millimetres. The majority of the annual
rainfall occurs in the summer months. The area experiences daily average temperatures varying
from 12.3 to 21.4 degrees.
The vegetation communities around the Georges River are primarily influenced by the
distribution of shale (Cumberland Plain) and sandstone (Woronora Plateau) geologies and
dominated by banksias, eucalyptus trees and several wattle species. RailCorp’s vegetation
maps indicate a bush regeneration area in the vicinity of the BTS site.
The immediate surrounding area drains into the Georges River. The site is approximately seven
kilometres from Towra Point Nature Reserve, which is a registered Ramsar site and a wetland
of international importance.
The proposed site is also is in close proximity to a number of heritage items. The Como rail
bridge is listed on the Register of the National Estate, State Heritage Register, RailCorp’s
Section 170 Heritage and Conservation Register and the Sutherland Local Environmental Plan
(LEP). The Como Pleasure Grounds and the Como Riviera Coffee Lounge (formerly Café de

Como) at 2 Cremona Road are listed as local heritage items (and included as indicative places
on the Register of the National Estate).

1.4 Consultation
The consultation activities for the proposed work are outlined below. These measures will help
ensure stakeholders are informed of the proposal and ensure that RailCorp meets 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 the RailCorp Communications Management Plan.
Three main consultation activities will take place:
1) Communication with local councils and regulatory authorities
Consultation with the local council and other regulatory authorities is required under the SEPP
(Infrastructure) 2007. This will include notification of and liaison with Sutherland Shire
Council/other government agencies/utilities is required with regard to temporary work impacts
may have on nearby community (traffic, parks, stormwater etc).
2) Communication with residents and businesses within a 500 metre radius of works and
at nearby train station
Consultation with nearby residents, schools and other community facilities is required. A
number of consultation activities will be undertaken and are outlined below.
• Letter: a letter will be sent to all properties within a 500 metre radius detailing the DTRS
project and the scope of works that will be undertaken for the Como BTS site.
• Display of REF: the final REF will be made available at www.railcorp.info before work
begins. Council will also be given a hard copy and a link to the DTRS section of the
RailCorp website.
• “Face to face” consultation: direct consultation will be undertaken with nearby residents.
Contact will be made with these residents and they will be given opportunities to discuss
the DTRS works.
• Contact hotline: a telephone number will be provided so the community can obtain further
information.
Community relations for the Como BTS proposal will specifically be targeted at:
• residents along parts of Cremona Road, Como Parade and Central Avenue; and
• business and community facilities near the proposed site (e.g. businesses within Como
Marina and the St George Rowing Club boatshed).
3) Notification and community relations during construction and commissioning works
with Council, nearby community and commuters at Como Station.
Additional information about the upcoming work will be provided to the nearby community and
Sutherland Shire Council at least five days before work begins. This information will include
specific detail regarding activities, works hours, traffic control measures and
compound/assembly location.

Communication with the community will take place before and during construction. Activities will
include “face to face” communications with nearby community members, notifications, contact
phone number and fact sheets.
DTRS fact sheets and signage will be at Como Station.
4) Summary
Feedback received during pre-construction consultation will be compiled into a summary report
and taken into consideration. It will then be used, along with the REF, to determine whether the
development should proceed 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 have been
undertaken in the context of Clause 228 of the Environmental Planning and Assessment
Regulation 2000, 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 RailCorp 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 Environmental Planning and Assessment Act 1979 (EP&A Act) establishes the statutory
framework for planning and environmental assessment in New South Wales. Implementation of
the EP&A Act is the responsibility of the Minister for Planning and Infrastructure, statutory
authorities and local councils.
The EP&A Act contains three parts which impose requirements for planning approval:
• Part 3A provides for control of ‘major infrastructure and other projects’ that require approval
from the Minister for Planning and Infrastructure;
• Part 4 generally provides for the control of local ‘development that requires development
consent from the local Council’; and
• Part 5 provides for the control of ‘activities’ that do not require development consent and
are undertaken or approved by a determining authority.
The applicable approval process is generally determined by reference to the relevant
environmental planning instruments and other controls. These include Local Environmental
Plans (LEP) and State Environmental Planning Policies (SEPPs). Pursuant to Section 36 of the
EP&A Act there is a general presumption that a SEPP prevails over a LEP in the event of an
inconsistency.
As RailCorp is the determining authority and this site falls under the definition of activities that
do not require consent, the approval of this site will be sought under Part 5 of the EP&A Act.
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.
2.3 Confirmation of Statutory Position
Clause 79(1) of the State Environmental Planning Policy (Infrastructure) 2007 (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 monopole, antennas
and BTS 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 any land.”
The proposal also meets the definition of a telecommunication facility under Clause 113 of the
ISEPP. RailCorp is a state-owned operating entity in the transport portfolio. It is classified as a
public authority under Section 4 of the EP&A Act.
Accordingly, this proposal (construction of a new BTS at Como) is being assessed under Part 5
of the EP&A Act. RailCorp 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. 4 Development Without Consent and
Miscellaneous Complying Development
The proposal is not classified as “exempt development” or “complying development” under the
provisions of SEPP 4.
State Environmental Planning Policy No. 14 Coastal Wetlands
This policy applies to local government areas outside the Sydney metropolitan area that front
the Pacific Ocean and is, therefore, not applicable.
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. Sutherland LGA is listed in
Schedule 1 as an area where bushland needs to be preserved. However, the proposed work
will not require the removal of vegetation, and so no further consideration of this SEPP is
required.
State Environmental Planning Policy No. 26 Littoral Rainforests
This policy applies to local government areas outside the Sydney metropolitan area that front
the Pacific Ocean (the same area which SEPP 14 applies to), and is therefore not applicable.
State Environmental Planning Policy No. 44 – Koala Habitat Protection
The proposed site is not located in an area nominated or classified by this SEPP as habitat for
koalas; therefore is not subject to the provisions of SEPP 44.
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 site falls outside the coastal protection zone designated in the Coastal Protection
SEPP, and therefore does not apply.
State Environmental Planning Policy (Major Development) 2005
This SEPP identifies certain developments which are deemed major projects under Part 3A of
the EP&A Act and which are then determined by the Minister for Planning and Infrastructure.
The proposal does not meet the criteria listed in Schedule 1 Section 23 (Rail and related
transport facilities), nor does it meet any of the other requirements listed in Schedules 2, 3 or 5.
This SEPP does not apply to the proposal.
State Environmental Planning Policy (Sydney Drinking Water Catchment) 2011
The proposed site is located in the Georges River catchment and is not part of a drinking water
catchment. This SEPP does not apply to the proposal.
Sutherland Shire Local Environmental Plan 2006
The proposed site is located in the Sutherland LGA and is subject to the Sutherland Local
Environmental Plan 2006 (Sutherland LEP). The proposed works would be undertaken in the
rail corridor, which is in Zone 21 – Railway.
Development for the purposes of railways is permissible in Zone 21 - Railway without consent,
under Clause 11 of the Sutherland LEP.

The State Environmental Planning Policy Infrastructure 2007 (ISEPP) also allows for the
proposal to 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.
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 any underground electricity power lines in the vicinity of the
proposed work, and
(b) complied with any 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…
(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 Office 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.

The proposed work is to be undertaken in an area where no State heritage items are located
and approval under the Heritage Act is not required. More information on 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. Further, the likelihood of
uncovering Aboriginal heritage items is considered low (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
In accordance with Section 55 of the Protection of the Environment Operations Act 1997 (POEO
Act), RailCorp holds an Environment Protection Licence (EPL), number 12208. The EPL applies
to the NSW Rail Network as defined in the Transport Administration Act 1988 for the purposes
of ‘railway systems’, which is a scheduled activity under the POEO Act.
Under the provisions of the licence, RailCorp is required to seek a modification to the licence for
certain ‘scheduled’ activities. However, the proposed works are not listed as a scheduled
activity under the POEO Act, and hence RailCorp is not required to seek a modification to its
licence under the POEO Act. Also, the works associated with the proposal will be confined to
land on which the rail undertaking is currently being carried out. As such, the proposed works
can be undertaken without requiring a variation to the EPL. Notwithstanding, the existing licence
requires that the licensee must comply with Section 120 of the POEO Act with regard to the
pollution of waters and must manage dust-generating activities.
Contaminated Land Management Act 1997
The Act establishes a process for investigation and remediation of potentially contaminated
lands. The Act is supported by a large number of guidelines which prescribe various aspects of
assessment and management of contaminated sites.
The land contamination is addressed in Sec 4.8 of the REF.

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.
Cremona Road will be used to access the proposed site and is not a classified road under the
meaning of the Roads Act. Further, no structures or works will be erected or undertaken on
Cremona Road. Approval from the Roads and Traffic Authority 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. Threatened species,
populations, endangered ecological communities are not likely to occur at the site and further
consideration under the act is not required.
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 would 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;
• 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.

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 proposal is not considered necessary.
Civil Aviation (Building Control) Regulation 1988
The regulation controls site and height of buildings that may affect flights. Buildings must not
penetrate any obstacle limitation surface shown on any relevant Obstacle Surface Plan that has
been prepared by a potentially affected airport or aerodrome. If a building is within the obstacle
limitations, an approval from Civil Aviation Safety Authority of Australia (CASAA) must be
obtained.
The proposed site is outside the restriction zones of Mascot Airport and provisions of the
regulation do not apply.
2.7 Ecological 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 ecologically sustainable development 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.
RailCorp is committed to ensuring its projects are consistent with the principles of ESD and the
principles of ESD have been considered for this proposal (refer Table 1).

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 monopole and cabinets can be removed, if no
longer required.
Any 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.

ESD Principle
Intergenerational equity
Conservation of
biological diversity and
ecological integrity
Application to the proposal
This proposal and the overarching DTRS project will contribute
towards RailCorp’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.
The proposed site is on disturbed land that has been previously
cleared. The proposed activity is not expected to result in any loss
of biodiversity or ecological integrity.
Improved valuation and
pricing of environmental
resources
RailCorp recognises the value of environmental sustainability and
will minimise the impacts of its activities by ensuring that
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.
2.8 Other Guidelines
Consideration of the NSW Telecommunication Facilities Guideline including Broadband NSW
(DoP 2010) is a requirement when Clause 114 or Clause 115 (development of a
telecommunications facility) of the ISEPP is applied. While the provisions of Clause 114 and
Clause 115 do not apply to the proposal, the guidelines have been considered and are included
at Appendix 1.

3 Description of the Proposal
Scope of Proposed Works
3.1.1 Summary
The outdoor BTS site at Como will consist of the following components:
• a 25 metre high monopole, plus a 1.5 metre high lightning rod at the top;
• two Argus panel antennas mounted on the monopole;
• power and BTS cabinets located on a slab two metres from the monopole;
• power supply cable from a new transformer/distribution supply main switchboard
approximately 90 metres away;
• fibre optic cable connection to the existing RailCorp pit 2ATJ0472 approximately 80 metres
away; and
• other associated and necessary activities to ensure proper functioning of the facility
including earthing, safe access and signage.
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 BTS Site
BTS Cabinet
The BTS cabinet will be placed on a precast concrete slab adjacent to the power cabinet
(described below) and will be oriented to the south-east. The cabinet will be painted stainless
steel, approximately 1700 millimetres high by 1000 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 cabinet will be powered via the power cabinet
described below.
The BTS cabinet will include the following equipment:
• BTS equipment (transceiver modules, transmission equipment, controller etc);
• DC distribution (including electromagnetic interference filter and surge protection);
• transmission interface (Huawei PTN910);
• fibre optic distribution frame;
• monitoring and reporting capability of power cabinet conditions; and
• a field monitoring device for radio frequency coverage. This requires a 12V DC input so is
installed with a 48V to 12V DC power converter.

Power cabinet
The power cabinet will be placed on a precast concrete slab adjacent to the BTS cabinet
(described above) and will be oriented to the south east. The cabinet will be painted aluminium
and approximately 1700 millimetres high by 1000 millimetres long by 880 millimetres wide. It will
be placed on a steel plinth which will have a minimum height of 200 millimetres to allow for the
management of cables entering the cabinet. The power supply will enter the cabinet via conduit
located at the rear of the cabinet.
The power cabinet will consist of the following:
• AC and earth terminations;
• 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).
Monopole
A 25 metre monopole with a bored pile foundation will be erected approximately two metres to
the north-east of the BTS and power cabinets in the rail corridor approximately 13 metres from
the south-bound track. The monopole will be hinged about 1200-1400 millimetres from the base
in order to assist its erection. However, once established, the hinge will be bolted to fix the
monopole in place.
Two Argus antennas will be mounted 24 metres above the ground with azimuths of 35° and
200°. 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 monopole for such
adjustments.
3.1.3 Power Supply
The supply to the Como power cabinet will be via a new distribution supply main switch board
(DSMSB) supplied via a new single phase 25kVA isolating transformer. This will be fed from a
new metering panel. The power source is approximately 80 metres from the DTRS site at the
pedestrian tunnel abutment at Cremona Road and will be routed to the DTRS site via new
underground conduits.

3.1.4 Fibre Optics
A new fibre optic route will involve the installation of two new 12 core single-mode optical fibre
cables between the BTS cabinet and existing pit 2ATJ0472 at Chainage SW20+338 where the
fibres will be spliced to the existing RailCorp bearer network. The total length of the cable run
will be approximately 80 metres. The fibre optic route will run from the BTS cabinet via two
separate conduits in a single trench to an existing cable pit at Chainage SW20+286. The optical
fibre cables will then be routed underground via an existing pit and pipe route to existing pit
2ATJ0472.
3.1.5 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 if the results show that the earthing arrangement is insufficient
3.2 Construction Methodology
The construction of the BTS site will require the use of approximately 300 square metres of land
within the eastern side of the rail corridor. This area will allow for the erection of the monopole
and the slab containing the BTS and power cabinets.
The monopole foundation will require an excavation approximately five metres deep with a
diameter of one metre. This will result in approximately four cubic metres of excavated material
which may include rock. The soil from excavations will be stockpiled before being used for
backfilling and/or disposed of site. Soil that cannot be used for backfilling, including rocks, will
be placed into a skip bin and removed from site at the completion of construction works. All
excavations will be covered during nights.
Installation of the earth grid, power and fibre optic cables will require excavation of trenches
approximately 1000 millimetres and 500 millimetres wide. The estimated length of all trenches is
200 metres. All trenching excavation will be backfilled before work finishes for the day. If this is
not practicable, trenches will be covered overnight.
The indicative construction methodology of the proposal will include elements outlined below.
• Non-destructive excavation before construction to establish underground installations.
• Site establishment.
• Excavation of the foundation for the monopole using excavator, drills or auger.
• Delivery and pouring of concrete on site for the monopole foundation.
• Installation of precast concrete slab brought to site for BTS and power cabinets.
• 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 monopole sections using trucks, cranes and riggers.
• Assembly of monopole and attachment of antenna mounts and cables before erection of
pole using the built in hinge joint.
• Connection of power and 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.
Materials used for construction and installation include concrete, gravel, steel plinth, steel
mounts, antennas, batteries, cables and radio equipment. It is not envisaged that any chemicals
or hazardous materials will be used during construction.
The majority of materials brought to the site will remain there once installed. Any excess
materials will be removed from the site and disposed of, reused or recycled. 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 batteries to be used are sealed, limiting the risk of leaking battery acid.
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)
• Crane where required (sized to suit the
application)
• 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
• Hand digging tools (shovels etc).
• Electrical hand tools
The use of a crane is further detailed in the Site Safety Management Plan and its location
indicated on a crane map - both are part of the project documentation.
The skip bin and the site compound area will be located within the rail corridor near the site. The
construction process will require an average of six vehicle movements and a team of three to
six people on site per day.
3.3 Timing and Costing
Construction works for the proposal is planned to start in the first quarter of 2012 and scheduled
to run for a period of six weeks
Proposed construction timing:
Standard working hours
Evening/Weekends/Out of hours:
Monday to Friday 7.00am to 6pm
Saturday 8.00am to 1.00pm
No night works or out of hours works proposed
No work on Sundays/public holidays
The DTRS project has an overarching value of $225 million. This includes the design, supply,
and installation of the DTRS on the RailCorp electrified network plus a five-year life support
component.
3.4 Alternatives to DTRS
As discussed earlier, the Waterfall Special Commission of Inquiry precipitated the
recommendations regarding communications in NSW rail operations and within RailCorp. The
NSW Government then committed to a state-wide strategy for all rail communications.
RailCorp investigated a number of alternatives already used by the state government or
available commercially, looking for a system that met its own safety and reliability requirements
as well as the recommendations of the Waterfall inquiry.
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
RailCorp personnel.
• It could not 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.
• Priority is given to emergency services which could result in a failure of 100% rail
network coverage.
• The network is both inside and outside the rail corridor.
• GRN would require a substantial upgrade, including new base stations, to ensure 100%
network coverage of the rail corridor.
• 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, 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 RailCorp’s
reliability requirements.
• It is not scalable in regards 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 RailCorp’s network.
• It relies on a dispatch terminal for functionality, which does not meet the RailCorp
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 RailCorp’s 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 RailCorp 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 RailCorp’s network.
• It operates on a spectrum of 1800 MHz which was available for purchase by RailCorp.
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 RailCorp 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 Como site
The following options were considered for the development of the Como site:
• to do nothing;
• install the antennas on existing communication facilities in the Como area; or
• Install a new BTS within the rail corridor near Como Station.
The do nothing option was rejected for the reasons listed below.
• The inability to meet the requirement of 100% network coverage.
• 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 so were not selected for this
proposal.
Radio frequency modelling also indicated that a new BTS at Como railway station would not
provide adequate coverage to the rail corridor. A second site would then be required, increasing
the costs and environmental risks of the proposal.

Other infrastructure options were considered, but were not feasible for the proposal.
• The proposed monopole is less obtrusive, requires less space and is cheaper to maintain
than a lattice tower or guyed mast. The proposed monopole also uses a foundation design
that is better suited given the spatial limitations within the rail corridor. The monopole is
thinner at the top and less obtrusive than a lattice tower helping to minimise the visual
impacts of the proposal.
• The monopole can be installed using a hinge mechanism, which removes the need for
large cranes.
• The installation of a walk-in equipment hut will use more space and is more expensive. The
use of outdoor cabinets was the most suitable solution given the limited space, cost and
minimisation of environmental impacts.
3.6 Justification of the Preferred Option
Overall this work, as part of the DTRS project, will result in significant benefits by providing a
more effective communications systems for the RailCorp network. The 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 RailCorp’s electrified rail network
The proposal for a BTS at Como, 800 metres north of Como railway station was selected
because it will enable the site to be consistent with the whole RailCorp DTRS network.
Consistent technology choice will enable RailCorp to improve its existing quality of service,
reliability and emergency responsiveness. The reasons for selecting the technology are
discussed above.
The Como site was selected due to its ability to cover the section of track between Oatley and
Jannali. The proposed antenna height (i.e. approximately 25 metres) is the minimum height
required to provide optimum radio frequency coverage in these sections of track.
The proposed site is also close to existing fibre and power supplies and has good construction
and maintenance access. The proposal will not require the removal of large amounts of
vegetation and there is an adequate buffer distance (at least 100 metres) to the nearest
residential receivers.
Due to the need to provide RF coverage to the tracks on both sides of the Georges River, the
site had to be close to the bridge across the river. There were no sites on the northern side of
the river that provided adequate access for construction, hence the site is on the southern side.
The site selected provides the best access with minimal visual impact to local residences.

4 Environmental Impact and Risks
4.1 Landforms, Geology and Soils
Existing Situation
The proposed site is inside the existing railway corridor approximately 12 metres east of the
south-bound track, near the heritage-listed Como rail bridge that crosses the Georges River.
The site is in a cleared, grassy area with some surrounding trees (refer Figure 4). The
monopole and cabinets will be located at the base of an embankment that slopes from the rail
line down to the fence.
The geology comprises Hawkesbury sandstone and the soil is of the Hawkesbury soil
landscape type. Soils in this area are typically shallow and stony and present an extreme
erosion hazard.
According to the NSW Acid Sulphate Soil Maps (NSW Department of Natural Resources) the
area does not contain Acid Sulphate Soils.
Figure 4
View of site looking west towards the rail line
Potential Impacts
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 a direct impact on water quality and aquatic life.

Given the site characteristics and the scope and size of the proposed work, t is anticipated that
erosion and sediment risks are minimal and can be effectively managed through the
implementation of standard measures outlined in the Landcom/Department of Housing
Managing Urban Stormwater, Soils and Construction Guidelines (the Blue Book) (Landcom
2004).
No operational impacts are expected.
Possible Control Measures
A site specific erosion and sediment control plan will be prepared as part of CEMP. This plan
will detail appropriate erosion and sedimentation control measures which will be implemented
during the construction phase. The measures will include, but not be limited to those outlined
below.
• All spoil not being used for backfilling 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/wheel wash facilities.
• Soil will be removed from public roads and other paved areas using dry street sweepers or
other measures.
• Disturbed areas will be replanted, if required.
During maintenance activities, any spills will be attended to and treated in an appropriate and
timely fashion in accordance with normal RailCorp management procedures.
4.2 Water Quality and Hydrology
Existing Situation
The nearest water body is the Georges River, approximately 40 metres away, which forms part
of the Georges River catchment. The suburban stormwater system is along the main roads (i.e.
Cremona Road) and some stormwater drains may be present around the construction footprint.
The groundwater depth and quality are not known
In addition to sediment-rich runoff, construction activities can generate contaminated water,
such as:
• liquid waste from non-destructive excavation;
• water from spills, and from washing equipment and tools;

• sewage from site amenities; and
• water collected in trenches and the pit.
Potential Impacts
Without appropriate safeguards, contaminants (e.g. fuel/chemicals from accidental spills,
sediment from excavations and stockpiles) may reach nearby drains and discharge into local
waterways. These contaminants have the potential to harm aquatic life and affect the quality of
water downstream. However, the risk of such an occurrence is low, given the distance between
construction works and drains and rivers.
Rain or groundwater may enter excavations. If inappropriately managed, sediment-laden
groundwater/rainwater in excavations could be discharged into the local water bodies and/or the
local stormwater system.
No operational impacts expected. The proposal will not affect the landform or the flow of water
in the area.
Possible 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 may include, but will not be limited to, those outlined below.
• Ensuring construction materials are not left in the vicinity of storm water drains;
• Trenches and excavations will be covered to prevent rain water 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 off site;
• Liquid waste generated during non-destructive excavation will be removed from the-site for
treatment and disposal;
• Groundwater/rain in trenches and/or the pit will be disposed of appropriately. The following
treatment and disposal options have been identified:
• disposal at an appropriate waste facility;
• discharge to the public sewer;
• discharge to the existing storm water system;
• land application; and
• reuse for vehicle cleaning and wash down.
• If groundwater is encountered and cannot be permanently removed, a plastic sleeve will be
placed into the bore hole prior to any concrete pour.

A water management plan will be prepared before construction begins to determine the most
appropriate method for disposal of water.
4.3 Air Quality
Existing Situation
Sutherland Shire Council’s State of the Environment Report 2009-2010 reported that the
regional air quality in Sutherland Shire was largely ‘good’. Local air quality is influenced by
traffic and railway emissions.
Potential Impact
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 approximately 2.3 to 2.7 kilograms of carbon
dioxide equivalent (CO 2 -e) emitted 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 RailCorp’s overall greenhouse gas emissions.
Possible Control Measures
Air quality impacts throughout construction will be minimised through a range of control
measures, which may 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.
• Minimal work will be undertaken during high wind periods.
• Trucks transporting spoil and other waste materials from site will be covered appropriately.
• Disturbed areas will be rehabilitated after construction.

4.4 Biodiversity
Existing Situation
At a national level there are 20 species of fauna, five species of flora and 19 migratory bird
species listed as threatened under the Environment Protection and Biodiversity Act 1999 (EPBC
Act). These species or their habitat may occur in the search area (refer Appendix 3). At a state
level there are recordings of 22 threatened fauna species and 16 threatened flora species listed
under the Threatened Species Conservation Act 1995 (TSC Act) within the search area (refer
Appendix 3). Given the absence of suitable habitat, it is unlikely that any threatened fauna
species will be present in the area.
The Towra Point Nature Reserve, which is a Ramsar-listed wetland and a matter of national
environmental significance matter listed under the EPBC Act, is approximately seven kilometres
away.
The immediate area around the proposed monopole and cabinet has been cleared previously,
however, there are number of trees in the vicinity, including some within 10 metres of the
proposed base of the monopole. Some of the trenching for the power and fibre connections will
extend through a regeneration area.
There are 83 species of noxious weeds identified in the Sutherland LGA. Weed control is
enforceable by Sutherland Shire Council, as the local control authority under the Noxious
Weeds Act 1993. RailCorp vegetation mapping also indicates that Lantana is in the proposed
area.
Potential Impacts
While there are several threatened species known to be present in the Sutherland LGA, the site
is in a disturbed area adjacent to the rail corridor, an area where there is no bushland or dense
vegetation. The proposed works do not include the removal of any of the existing trees.
The works are not expected to impact any listed threatened species or endangered ecological
communities. Given the relatively minor nature of work and distances, the Tower Point Reserve
is unlikely to be affected
Excavation works have the potential to affect nearby trees if roots are damaged during
excavation or from equipment impacting trees.
Once soil has been disturbed there is the potential for the spread of weeds. Noxious weeds are
known to occur in the Sutherland area, including Lantana.
With regards to fauna, the proposal will not remove vegetation or any 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.

Possible Control Measures
Impacts on flora and fauna throughout construction will be minimised through a range of control
measures which may include, but will not be limited to, those outlined below.
• No trees will be removed during construction.
• Care will be taken to minimise the spread of weeds. Appropriate management and disposal
of any noxious weeds, will be undertaken in consultation with Sutherland Shire Council.
• The work site will be inspected for any 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.
4.5 Noise and Vibration
Existing Situation
The adjacent railway line, local traffic and noise from the various recreational facilities in the
vicinity (bike paths, river, rowing club, marina and sporting field) are the major sources of noise
in the area.
The closest receivers are commercial properties; approximately 50 metres away at the Como
Marina (refer Section 4.9). Residential receivers are approximately 100 metres away on Como
Parade and 240 metres away on Cremona Road.
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, retail and schools.
The ICNG states:
• that where the predicted or measured noise level is greater than the noise management
level, the proponent should apply all feasible and reasonable work practices to meet the
noise affected level;
• that 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; and
• that 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 is likely to be created by construction trucks, machinery and, in particular, boring activities
required to establish the foundations for the monopole. These activities will be of a short
duration.

Construction is expected to take between four and six weeks and all works will be undertaken
during standard working hours. Given this, background noise monitoring and the establishment
of noise management levels for residential receivers is not proposed. The ICNG does, however,
prescribe a highly noise affected criteria of 75 dBA L Aeq, 15min, which is the point where there may
be strong community reaction to noise. Given the offset distance and the natural vegetation
barrier, it is unlikely that dwellings, commercial premises or schools will experience a noise level
above the highly affected level of 75 dBA L Aeq, 15min during the noisiest works.
A range of standard construction noise mitigation measures is proposed to minimise noise (refer
Table 2), and the community will be notified and provided with details of the works before
construction begins.
Construction Vibration
Vibration effects from the operation of heavy machinery, such as vibratory rollers or large earth
moving equipment have the potential to cause structural disturbance or discomfort. The
proposal will not require the use of vibration-causing heavy machinery.
Discomfort effects will not be expected given the types of machinery required for construction
works and offset distances. Similarly, structural damage to buildings is not expected given the
nearest building is 50 metres away.
Operational Noise and Vibration
No operational impacts are expected.
Possible Control Measures
Construction works will adopt Best Management Practice (BMP) and Best Available Technology
Economically Achievable (BATEA) practices as addressed in the ICNG (DECC 2009).
In addition to the control measures listed in Table 2, the community will be notified of the works,
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 undertaken on 23 June 2011 consulting the
following databases: Sutherland Local Environmental Plan (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.
There are a number of heritage items around the proposed site (refer Appendix 3). These are
listed below.
• The Como rail bridge, located approximately 50 metres north of the proposed site, which
has been converted to a pedestrian and bike path and is listed on the Register of the
National Estate, State Heritage Register, RailCorp’s Section 170 Register and Sutherland
LEP heritage schedule.
• The Como Pleasure Grounds, approximately 100 metres south-east of the proposed site, is
listed as an indicative place on the Register of the National Estate and the Sutherland LEP
heritage schedule.
• Como Tidal Pool, approximately 100 metres south-east of the proposed site, is listed as an
indicative place on the Register of the National Estate.
• Oatley Underbridge which extends across the Georges River is listed on RailCorp’s
Section 170 Register.
• The Como Riviera Coffee Lounge (formerly Café de Como) is approximately 100 metres
south-east of the proposed site, and listed on the Sutherland LEP heritage schedule.
A search for known items of Aboriginal heritage value was undertaken for the proposed site,
(with a 50 metre buffer) on 20 June 2011 using the Office of Environment and Heritage’s
Aboriginal Heritage Information Management System (AHIMS). No Aboriginal sites or places
were found at the proposed location or in the surrounds (refer Appendix 3).
Potential Impacts
The works are unlikely to impact on any known items or places of non-Aboriginal heritage value.
All works will be undertaken away from known items. No permits or approvals will be required.
The construction works will not impact any 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.

Figure 5
Looking south from the Como rail bridge towards the proposed site
Possible Control Measures
Impact on heritage throughout construction will be minimised through a range of control
measures which may 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. RailCorp heritage staff and the Heritage Branch
(formerly Heritage Office), 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 RailCorp heritage staff will be notified immediately. The Manager of
the Planning and Aboriginal Heritage Section, Metropolitan Branch, Environment Protection
and Regulation Division, OEH will be notified in accordance with Section 89A of 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 any other requirements before work resumes.
4.7 Waste
Existing Situation
RailCorp 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, but the proposed activities will generate a range of different wastes.
Potential Impact
The main waste streams that may be generated during construction include:

• spoil from excavation;
• concrete;
• packaging; and
• general litter including glass, plastic, metal and paper waste.
No operational impacts are expected.
Possible 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 may include, but not be limited to, those outlined below.
• All waste will be classified in accordance with the Waste Classification Guidelines (DECCW
2009) and transported to a place that can lawfully accept the waste.
• Any material that may be classified as a hazardous waste will be dealt appropriately and in
accordance with RailCorp 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.
• Any 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.
• All waste will be removed from the site when work is completed.
4.8 Contaminated Land
Existing Situation
The site has been investigated for potential land contamination. The investigation included:
• a visual inspection for signs of potential land contamination;
• a search of NSW 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.
The initial investigation did not find any signs of potential land contamination, other than those
typically associated with rail corridors. There are no visible and/or obvious signs of

contamination in the vicinity of the site. No waste dumping, soil discoloration, odours and/or
similar were noticed.
RailCorp does not have any record or evidence that the site may be contaminated. There are no
contaminated sites in the suburb of Como listed on the NSW register.
Hazardous materials will not be used during construction and operation and, therefore, the
proposed work will not result in any new site contamination.
Possible Control Measures
It is highly unlikely that the site can be contaminated by known activities or by contaminants
migrating from the known contaminated sites.
However, the limited 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.
Risk Management and Possible Controls
The risk of encountering unknown contaminants during excavation will be managed in
accordance with RailCorp procedures, the Environmental Management Plan for DTRS project
and land contamination legislation.
The impact of potential contaminants will be minimised through a range of control measures
including, but not 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, work will stop immediately and the
site will be fenced off.
• Any potential contamination will be investigated and work resumed only when approved
by the Site Supervisor.
• A remedial action plan will be prepared before clean up operations begin.
• The site will be validated before work begins.
• Contaminated soil will be segregated in a special container before classification and
disposal.
The CEMP will further detail the proposed control measures.

4.9 Hazardous Materials
Existing Situation
Construction, operation and maintenance of the proposed facility will not require the use of any
chemicals and/or hazardous materials. However, if required for any unforeseen reason, a
hazardous materials management plan will be prepared. The plan will detail terms applying to
the purchase, storage, use, handling and disposal of such materials.
Potential Impact
If not properly used, chemicals may present a risk to the safety of workers and the environment
in general.
Safe use of chemicals is regulated and subject to numerous standards, including a need for a
dangerous goods licence.
Possible Control Measures
If hazardous materials are to be used, their impact 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 any 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 bunded area at the site;
incompatible chemicals will not be stored together.
• No fuels will be stored on site. Any 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.
The site CEMP will further detail these measures, should they be required.

4.10 Visual Aesthetics and Urban Design
Existing Situation
The visual landscape surrounding the proposed site includes the Illawarra railway line,
associated overhead power lines and communications poles (refer Figure 5). There is
vegetation lining the fence of the rail corridor, and an existing substation to the south.
The proposed site is visible to pedestrians and cyclists exiting from the Como rail bridge and
passing along the access path. The closest commercial receivers are located at the Como
Marina, 50 metres away. Residential dwellings are approximately 100 metres away on Como
Parade and Central Avenue. Residential dwellings are also approximately 240 metres away on
Cremona Road.
Figure 5
View looking towards the city and the Como Rail Bridge showing trees and rail
Potential Impacts
During construction the visual environment will be temporarily altered through the presence of
temporary work buildings, plant and equipment such as cranes and trucks.
During operation, a new 25 metre high monopole will be introduced into the visual environment.
The 1.7 metre high cabinets will be of little visual significance.
A consideration of the impact of the new monopole should consider visual sensitivity and visual
magnitude. A photomontage of the new monopole is displayed in Figure 6 and 0.
Visual sensitivity relates to the number of people who will be likely to see the facility and their
possible expectations of visual quality. For example, commercial properties are generally
considered less sensitive than private residences. The site will be in an area where there is lowmoderate
sensitivity given the distance of residential receivers and that there will be a relatively

small number with direct views of the monopole. Most of these receivers are also shielded by
vegetation and, depending on the view shed angle, only the top section of the monopole may be
visible. Pedestrians and cyclists will be able to see the monopole as they cross the Como rail
bridge and will experience and expect scenic views of the river and bridge along the access
path.
The visual magnitude is derived from scale and the level of visual contrast between the
proposed facility and the existing visual environment. The new steel monopole will be
approximately 25 metres high and close to existing overheard wires that have a similar visual
appearance. The monopole is not a bulky structure and will not be a dominant part of the visual
landscape.
Visual impact is then generally determined by reference to both visual sensitivity and visual
magnitude. Various combinations of visual sensitivity and visual magnitude produce low,
moderate and high levels of impact. For this proposal the sensitivity of the area is low-moderate
given the presence of residential receivers, along with users of the pedestrian/bike path. The
magnitude of the impact area will be low as the monopole is not bulky and is consistent with
other elements in the visual surrounds. The overall impact is considered to be low-moderate.

Photomontage looking north towards Oatley

Possible Control Measures
Visual impact will be minimised through a range of control measures, which may include, but
will not be limited to, those outlined below.
• The construction site will be kept tidy and rubbish free.
• The site will be rehabilitated as soon as possible.
• On completion of work, all vehicles, materials and refuse relating to the works will be
removed.
4.11 Land Use
Existing Situation
The proposed site is on land owned by RailCorp and zoned for the purposes of a railway under
the Sutherland LEP. The land where the new monopole and cabinets are to be situated is not
actively used for any RailCorp activities (e.g. an access route or storage area) and so the
proposal will not affect any existing uses of the land. The immediate neighbouring land uses
include recreational (Como rail bridge pedestrian/bike path) and commercial (Como Marina).
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 any effects on the use of the neighbouring land.
Possible Control Measures
No specific control measures are required.
4.12 Socio-Economic Effects
Existing Situation
The proposed site is in the Sutherland LGA, which in the 2006 census had a population of
around 205,000. The main employment areas are schools and education, cafes and restaurants
and legal and accounting. The suburb of Como is largely a residential suburb next to the
Georges River.
The Como Marina is located approximately 50 metres from the proposed site and comprises a
number of commercial premises (e.g. a mechanic and cafes). The Como Pleasure Grounds,
Como Pool Complex, St George Rowing Club boathouse and Scylla Reserve are all in the
vicinity. The Como rail bridge has been converted to a pedestrian/bike path which extends from
Oatley down to Como and along Cremona Road.
Residential dwellings are at least 100 metres south-west off Como Parade and Central Avenue
and along Cremona Avenue to the south-east.
Potential Impacts
Social and economic considerations typically focus on the effect on the local community as a
whole, and on any 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
4.10 and 4.14.
The construction of the site is unlikely to have any adverse effect to nearby
businesses/recreational facilities, as the construction will be contained within the rail corridor.
Noise impacts will be temporary (less than six weeks). There will be no major traffic or access
changes to any businesses, residents or the pedestrian/bike path.
No additional track work will be required, so there will be no additional interruptions to train
services as a result.
The site will be appropriately fenced off during construction. In operation, the site will be fenced
off, so will pose 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 rail communications service and improve the safety of the rail network.
The proposal will have minor short-term positive impacts for the wider 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 8-year period.
Possible Control Measures
In addition to the measures proposed in the noise, traffic and visual sections, the following
measures are also recommended:
• Nearby residents and businesses will be informed about the nature and timing of works.
• If any out of hours work is required, surrounding receivers will be notified at least five days
in advance.
• Signage will notify the public about the works.
• Appropriate fencing around the site will help maintain public safety during construction.
4.13 Electromagnetic Energy (EME)
Existing Situation
Electromagnetic energy (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
communication facilities.
The Australian Radiation Protections and Nuclear Safety Agency (ARPANSA) have 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 new BTS have been estimated at 1.5 metres above ground level at
various distances from the proposed antennas. The maximum cumulative EME level at 1.5
metres above the ground is estimated to be 0.031% of the ARPANSA exposure limits (Appendix
D). It is further noted that the actual EME will be significantly lower than predicted due to path
losses and because the BTS automatically minimises transmitter power to serve only
established phone calls.
Possible Control Measures
The BTS will be located in RailCorp land in an area which is not accessible by the public and
has been designed so that it cannot be climbed. However, the following control measures are
also recommended to 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.
4.14 Traffic and Access
Existing Situation
Access to the proposed site will be via an existing RailCorp access gate off Cremona Road. 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 RailCorp staff and contractors use the gate and
access track around 20-30 times a year. A pedestrian/bike path extends along the Como rail
bridge and down past the Como Marina.
Potential Impacts
During construction, there will be an increased number of vehicles using the local streets. The
volume of traffic along Cremona Road is not normally high, as it is a local road used by
residents/visitors and not a main thoroughfare. The anticipated volume of traffic is relatively
small (approximately four to six truck movements per day) and is unlikely to impact local traffic.
As works are to take place in the rail corridor near the Como rail bridge there is not expected to
be any access changes to local roads or access to driveways. An area around the pedestrian
tunnel at Cremona Road may be cordoned off to allow for electricity connection works, however
through access will be maintained. There will be no further changes required to the
pedestrian/bike path.
As there are overhead power lines that extend along the track, a clearance of three metres must
be maintained when construction vehicles access the proposed site.
There will be some traffic movement associated with vehicles that will need to access the
proposed site through the commuter car park 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 monopole and antennas be accessed via an elevated work
platform or through the use of a ladder and dual lanyard system.
No additional trackwork will be required, so there will be no additional interruptions to train
services as a result.
Possible Control Measures
Impacts associated with traffic and access will be minimised through a range of control
measures, which may include, but will not be limited to those outlined below.
• A Traffic Management Plan will be developed for the proposed works.
• A dilapidation survey will be completed before demobilisation.
• Any pavement or road surfaces that are damaged as a result of construction works will be
restored when work is finished.
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. These services should be identified before construction work begins. Several
methods, including non-destructive excavation will be used to allocate underground
installations.
Potential Impacts
The impact of non-destructive excavation has been discussed in other sections of the REF.
The proposal will be connected to the existing electricity and fibre supply and does not require
connections to any water or gas. RailCorp have an existing metered power supply and will
continue to use this existing supply. No overhead wires will need to be relocated.
A number of public utilities are in the vicinity of the site and there is potential for some known or
unknown services to be impacted during excavation or during relocation/connections.
Depending on the service, outages or interruptions could affect nearby properties or the rail
network.
Possible Control Measures
• Ensure that a Dial Before You Dig and RailCorp services search is undertaken to identify
services.
• Public utility providers will be consulted to minimise the impacts during any utility
relocations or readjustments.
4.16 Light spill
Light spill impacts will not occur as night works are not proposed. In addition, there is no new
permanent lighting proposed. No further consideration of light spill is considered necessary.

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 can result when several different construction projects are scheduled for
similar times and locations.
A search of the Department of Planning’s Major Projects register did not identify major projects
in the vicinity of the proposed site. Similarly, a search of major development applications around
the proposed area did not identify any large projects in the vicinity of the proposal and which
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 Como BTS site is one of a large number of radio communications facilities being installed
across the RailCorp network as part of the DTRS project. In terms of localised cumulative
construction impacts, the nearest proposal for the DTRS Project is the Oatley site, which is
located approximately 1.8 kilometres north-east of the proposed site. Even if both facilities were
constructed simultaneously, it is not likely to result in cumulative noise or local traffic impacts.
Proposed Control Measures
• Any other major development or works planned in the vicinity of the proposal will be
investigated before work begins.
• Sutherland Shire Council and any other relevant stakeholders will be consulted regarding
other developments will be undertaken on an ongoing basis.
4.19 Consideration of Clause 228 of EP&A Regulations and EPBC Act
Clause 228 Factors
Clause 228(2) of the EP&A Regulation 2000 details factors that must be taken into account

The proposed control measures described at the end of each environmental impact section in
this REF will be incorporated into a Construction Environmental Management Plan (CEMP).
The CEMP is the key environmental management document that the Project Manager will follow
during construction and commissioning to ensure appropriate environmental management
practices are followed.
The construction contractor will prepare the CEMP incorporating environmental mitigation
measures for construction works including the control measures specified in this REF. The
CEMP will be prepared in accordance with the Guideline for the Preparation for Environmental
Management Plans (DIPNR 2004).
A copy of this REF and the CEMP will be retained on site and produced upon request. The
CEMP will include:
• details of environmental controls to be implemented including location and timing;
• details of statutory requirements including any approvals and licences;
• assignment of responsibility for implementation and monitoring of environmental controls;
• reporting and emergency procedures;
• contact details for all site personnel and agency contacts; and
corrective action requirements and their verification.

Appendix 1: Principles from the Telecommunication
Facilities Guideline
Principle 1: A telecommunications facility is to be designed and sited to minimise visual
impact.
Principal
(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.
(e) A telecommunications facility should be
located and designed to respond
appropriately to its rural 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.
Proposal
The proposed facility does not involve
mounting antennas to a building or structure.
The design and site selection has aimed to
minimise the visual impact of the proposal.
This has been achieved by selecting a location
inside the rail corridor where there is already a
level of disturbance as well as trees along the
edge of the rail corridor. The selection of a
monopole and antenna mounting system that
is unobtrusive with minimal visual bulk has
also minimised the visual impact.
The proposal does not involve mounting
antennas to a building or structure.
The outdoor cabinets will be located adjacent
to the base of the monopole. The cabinets are
less than two metres high and will not be
visible from public access points
The proposal is not located in a rural area. It is
located in the rail corridor adjacent to a
residential/commercial land uses.
The visual elements of the proposed work are
not located on or within a heritage item.

Principal
(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 any 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 any relevant Industry
Design Guides.
Proposal
The proposal will not block or significantly
obstruct any views of heritage items or other
landmarks of state significance.
The proposed monopole is less than 500 mm
wide at the top and there is no headframe
supporting the antennas. The monopole will
not represent a dominant structure in the view
lines of people occupying the residential
properties in the surrounding area.
It is unlikely that any trees will need to be
removed however any trees that may need to
be removed will be located on RailCorp land
and are not subject to tree preservation
orders. Tree replanting will be investigated,
should tree removal be required.
Should the proposal ever become redundant,
the various elements will be decommissioned
and removed. Following the removal, the land
will be restored as close as practicable to its
condition prior to the works commencing.
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.
Principal
(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.
Proposal
The fibre connections for the DTRS network
will be located in existing conduits or in new
underground conduits wherever feasible or
possible.
The co-location of the proposal 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
monopole is been proposed.

Principal
(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 any new telecommunications
facility must be designed, installed and
operated so that the resultant cumulative
levels of radio frequency emissions of the colocated
telecommunications facilities are
within the maximum human exposure levels
set out in the Radiation Protection Standard.
Proposal
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.
There are no suitable communications
towers in the target coverage area that will
satisfy the coverage objectives as well as the
network requirements of the DTRS project
The proposal is not a co-location.
Principle 3: Health standards for exposure to radio emissions will be met.
Principal
(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 proposal 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
Principal
(a) The sitting and height of any
telecommunications facility must comply with
any 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 any obstacle limitation
surface shown on any relevant Obstacle
Limitation Surface Plan that has been
prepared by the operator of an 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 any 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
(if any) of the manufacturers for the installation
of such equipment.
(d) The telecommunications facility is not to
affect the structural integrity of any 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’ (Landcom 2004), 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.
Proposal
The provisions of the Civil Aviation
Regulations 1988 and the Airports (Protection
of Airspace) Regulations 1996 have been
considered during the design and sitting of the
proposal.
RailCorp will operate the radio facility with its
own spectrum and the facility will not cause
any interference with other networks. All radio
transmitters will use the frequency assigned to
RailCorp for the exclusive use of RailCorp.
The installation and operation of the radio
equipment and antennas will be carried out in
accordance with the manufacturer’s
specifications.
The proposal is not connected to an existing
building.
The proposed facility will be within the rail
corridor that is owned and used by RailCorp.
RailCorp are the proponents of the network
agree to the use of the land for the proposed
radio equipment.
The activities associated with the construction
and installation of the proposal will be done in
accordance with sediment controls, erosion
controls, stormwater controls and other
controls outlined in the Blue Book (refer
Section 4.1).
Most construction activities will take place in
the rail corridor. Any traffic changes will be
implemented in accordance with an approved
Traffic Management Plan.
There will be no risks to traffic or pedestrians
when the facility is operational.

Principal
(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
and 6.00pm, Mondays to 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.
(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
Proposal
All work associated with the development and
installation of the between 7.00am and
6.00pm, Mondays to Fridays and 8.00am to
1.00pm Saturdays, with no work on Sundays
and public holidays.
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).
All open trenches in the road will be guarded
as per Australian Standard Section 93.080 –
Road Engineering AS1165 – 1982 – Traffic
hazard warning lamps.
All trenches will be covered or filled so that
they are not open overnight.
Tree removal is not proposed as part of the
works. However should the works require the
removal of any trees, suitable replanting will
be undertaken upon completion of the
installation activities (refer Section 4.4).
The proposed activities do not require the
removal of significant amounts of vegetation.
A search of threatened species has been
completed (refer Appendix 3) and there is not
expected to be any significant impacts on any
threatened species.
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 there are any suspicious items or objects
found during any excavation works, the work
will cease immediately and the OEH will be
consulted and works will not re-commence
until OEH have granted their consent.
All street furniture, paving and walkways will
be reinstated at the end of construction to at
least the same condition as which they existed
prior.

Other Matters Protected by the EPBC Act
This part of the report summarises other matters protected under the Act that may relate to the area you
nominated. Approval may be required for a proposed activity that significantly affects the environment on
Commonwealth land, when the action is outside the Commonwealth land, or the environment anywhere
when the action is taken on Commonwealth land. Approval may also be required for the Commonwealth
or Commonwealth agencies proposing to take an action that is likely to have a significant impact on the
environment anywhere.
The EPBC Act protects the environment on Commonwealth land, the environment from the actions taken
on Commonwealth land, and the environment from actions taken by Commonwealth agencies. As
heritage values of a place are part of the 'environment', these aspects of the EPBC Act protect the
Commonwealth Heritage values of a Commonwealth Heritage place and the heritage values of a place on
the Register of the National Estate. Information on the new heritage laws can be found at
http://www.environment.gov.au/heritage/index.html
Please note that the current dataset on Commonwealth land is not complete. Further information on
Commonwealth land would need to be obtained from relevant sources including Commonwealth

Caveat
The information presented in this report has been provided by a range of data sources as acknowledged at
the end of the report.
This report is designed to assist in identifying the locations of places which may be relevant in
determining obligations under the Environment Protection and Biodiversity Conservation Act 1999. It
holds mapped locations of World Heritage and Register of National Estate properties, Wetlands of
International Importance, Commonwealth and State/Territory reserves, listed threatened, migratory and
marine species and listed threatened ecological communities. Mapping of Commonwealth land is not
complete at this stage. Maps have been collated from a range of sources at various resolutions.
Not all species listed under the EPBC Act have been mapped (see below) and therefore a report is a
general guide only. Where available data supports mapping, the type of presence that can be determined
from the data is indicated in general terms. People using this information in making a referral may need to
consider the qualifications below and may need to seek and consider other information sources.
For threatened ecological communities where the distribution is well known, maps are derived from
recovery plans, State vegetation maps, remote sensing imagery and other sources. Where threatened
ecological community distributions are less well known, existing vegetation maps and point location data
are used to produce indicative distribution maps.
For species where the distributions are well known, maps are digitised from sources such as recovery
plans and detailed habitat studies. Where appropriate, core breeding, foraging and roosting areas are
indicated under 'type of presence'. For species whose distributions are less well known, point locations are

collated from government wildlife authorities, museums, and non-government organisations; bioclimatic
distribution models are generated and these validated by experts. In some cases, the distribution maps are
based solely on expert knowledge.
Only selected species covered by the following provisions of the EPBC Act have been mapped:
- migratory and
- marine
The following species and ecological communities have not been mapped and do not appear in reports
produced from this database:
- threatened species listed as extinct or considered as vagrants
- some species and ecological communities that have only recently been listed
- some terrestrial species that overfly the Commonwealth marine area
- migratory species that are very widespread, vagrant, or only occur in small numbers.
The following groups have been mapped, but may not cover the complete distribution of the species:
- non-threatened seabirds which have only been mapped for recorded breeding sites;
- seals which have only been mapped for breeding sites near the Australian continent.
Such breeding sites may be important for the protection of the Commonwealth Marine environment.

Appendix 4: Electro-Magnetic Energy (EME) Reports
Refer attached document:
• DTRS-R-017-EM-0001: Como Electro-Magnetic Energy Report (APRANSA Report)

Summary of Estimated RF EME Levels around the
Rail Corp DTRS Site 17, Como NSW-2226.
Introduction: Date 29/04/2011 DTRS-R-017-EM-0001_A
Released
This report summarises the estimated maximum cumulative radiofrequency (RF) electromagnetic energy (EME) levels at
ground level emitted from the RailCorp DTRS Site 17, Como NSW-2226. Maximum EME levels are estimated in 360 circular
By: Robert Mahood
bands out to 500m from the base station. The procedures for making the estimates have been developed by the Australian
Radiation Protection UGL Infrastructure
And Nuclear Safety Agency (ARPANSA) 1 . These are documented in the ARPANSA Technical Report;
“Radio Frequency Date: EME 07/05/2011 Exposure Levels Reviewers: - Prediction Methodologies” PD,LB which is available at http://www.arpansa.gov.au
EME Health Standard
ARPANSA, an Australian Government agency in the Health and Ageing portfolio has established a Radiation Protection
Standard 2 specifying limits for continuous exposure of the general public to RF transmissions at frequencies used by mobile
phone base stations. Further information can be gained from the ARPANSA web site.
The Australian Communications and Media Authority (ACMA) 3 mandates exposure limits for continuous exposure of the
general public to RF EME from mobile phone base stations. Further information can be found at the ACMA website

Table_A: Estimation for the maximum level of RF EME at 1.5m above the ground from the proposed antennas assuming level ground. The
estimated levels have been calculated on the maximum mobile phone call capacity anticipated for this site. This estimation does not include
possible radio signal attenuation due to buildings and the general environment. The actual EME levels will generally be significantly less than
predicted due to path losses and the base station automatically minimising transmitter power to only serve established phone calls 5 . Where
applicable, particular locations of interest in the area surrounding the base station, including topographical variations, are assessed in Appendix
A “ Other areas of Interest” table on the last page.
Summary –Proposed Radio Systems
RF EME levels have been estimated from the proposed antennas at Como site. The maximum cumulative EME level at 1.5 m
above ground level is estimated to be 0.0013 % of the ARPANSA public exposure limits.

4. The EME predictions in this report assume a near worst-case scenario including:
- base station transmitters operating at maximum power (no automatic power reduction)
- simultaneous telephone calls on all channels
- an unobstructed line of sight view to the antennas.
In practice a worst-case scenario is rarely the case. There are often trees and buildings in the immediate vicinity, and cellular
networks automatically adjust transmit power to suit the actual telephone traffic. The level of EME may also be affected where
significant landscape features are present and predicted EME levels might not be the absolute maximum at all locations.
