Executive SummaryNeed for the ProposalTransport for New South Wales (TfNSW) currently operates an analogue train radio systemknown as MetroNet for operational communications between signallers and train drivers. Thissystem has reached the end of its serviceable life and requires replacement. The New SouthWales Government and TfNSW have begun work on the implementation of a Digital Train RadioSystem (DTRS) which will replace this analogue system and address a number ofrecommendations from the Waterfall Special Commission of Inquiry. The DTRS will be a securedigital train radio system designed to provide reliable voice and data communications on aGlobal Systems Mobile – Railway (GSM-R) platform.The DTRS will provide 100% radio coverage across the 1,455 kilometres electrified rail network.The DTRS has an expected design life of at least 15 years. UGL Infrastructure has beencontracted to design, construct, commission and maintain the DTRS.Proposal DescriptionThe proposal at Hurstville West Portal is for a new outdoor Distributed Base Station (DBS) siteand additional installations within Hurstville Station. The DBS site is referred to as OutdoorLocation 2 and the two installations at Hurstville Station and Apparatus Room are referred to asEquipment Location 3 and 4. A 10 metre monopole and associated antennas (at OutdoorLocation 2) will be installed in a cleared, gravel area about 10 metres north of the EasternSuburbs and Illawarra Line. Hurstville Station is about 130 metres east of the proposed OutdoorLocation 2 site.The proposal also includes installation of a DBS and power cabinet at the end of Platform 3 and4 of Hurstville Station and Yagi antennas mounted on the west end portal of the HurstvilleStation Tunnel (Equipment Location 3).A DTRS cabinet will also be installed in the Hurstville Apparatus Room 40 metres north-west ofOutdoor Location 2, at Equipment Location 4.A DTRS site has been assessed and approved at Outdoor Location 1 at Hurstville, henceOutdoor Location 1 at Hurstville will not be discussed in this REF.The proposed work for Outdoor Location 2 will involve the elements listed below.A 10 metre high monopoleTwo Yagi antennas to be mounted on the 10 metre monopoleFibre optic cable connection from the mast to existing pit approximately 6 metres away andthen via existing cable routes to the DBS /power cabinet to be installed at end of Platform 3and 4.Page 4 of 75

Equipment Location 3 comprises:Two Yagi antennas mounted on the soffit (underside of the ceiling) of the west end portal ofthe tunnelDBS/power cabinet installed at end of Platform 3 and 4Fibre optic cable connection from DBS/power cabinet located at the end of Platform 3 and 4to the Apparatus Room (Equipment Location 4)Two radio remote units (RRU) will be installed next to the cabinet.Equipment Location 4 at Hurstville Apparatus Room comprises:DTRS cabinet to be installed within the Apparatus Room 40 metres north-west of OutdoorLocation 2Fibre optic cable connection from the Apparatus Room to the TfNSW fibre terminationcabinet and from the Apparatus Room to the DBS/power cabinet located at the end ofPlatform 3 and 4.Approval ProcessThe proposal is being assessed under Part 5 of the Environmental Planning and AssessmentAct 1979 (EP&A Act) which requires TfNSW to consider the environmental impacts of theproposal.This Review of Environmental Factors (REF) has been prepared to address the requirements ofthe EP&A Act. It assesses the potential environmental impacts of the proposal within thecontext of Clause 228 of the Environmental Planning and Assessment Regulation 2000 (EP&ARegulation) and the Threatened Species Conservation Act 1995 (TSC Act). The requirementsof the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBCAct) are also considered.Environmental Impact AssessmentThe benefits of the proposal cannot be achieved without some degree of environmental impact.The impacts resulting from construction and operation of the facility have been assessed in thisREF. This REF identifies that, subject to the implementation of mitigation measures, potentialenvironmental impacts can be controlled and reduced to acceptable levels and would notsignificantly affect the environment.The main environmental issues relate to construction impacts such as erosion andsedimentation risks as well as short-term traffic, air quality and noise issues for nearbyreceivers. Such impacts will be managed through the implementation of a ConstructionEnvironmental Management Plan (CEMP) and site-specific ECM.In the long term, a new monopole and the new antennas will be introduced into the visuallandscape. The 10 metre high monopole will be screened from residential receivers by largePage 5 of 75

uildings and vegetation to the south of the rail corridor. The top of the monopole may be visibleto some nearby businesses on the north side of the railway corridor as there is no screening.Electromagnetic energy (EME) impacts have also been considered and the EME levels for theproposal will be well within the limits set by the Australian Radiation Protection and NuclearSafety Agency (ARPANSA).Environmental ManagementFollowing determination of the project, construction works will be undertaken in accordance withthe program wide CEMP and site specific ECM. The CEMP and ECM will further detail REFmitigation measures and will be prepared in accordance with the following:Guideline for the Preparation of Environmental Management Plans (Department ofInfrastructure, Planning and Natural Resources, 2004)The Environmental Management Plan for DTRS (UGL Infrastructure, 2010)TfNSW Guide to Environmental Control Map (2012).The following sub-plans are proposed in the REF and will be prepared concurrently with theCEMP and/or ECM as appropriate:Erosion and Sediment Control PlanWater Management PlanWaste Management PlanTraffic Management Plan.The program wide CEMP and site specific ECM will be reviewed and approved by TfNSW priorto the commencement of construction..Page 6 of 75

1 Introduction1.1 Background to the ProjectTfNSW currently operates an analogue train radio system known as MetroNet for operationalcommunications between signallers and train drivers. This system has reached the end of itsserviceable life and requires replacement. The New South Wales Government and TfNSW havebegun work on the implementation of a Digital Train Radio System (DTRS) which will replacethis analogue system and address a number of recommendations from the Waterfall SpecialCommission of Inquiry regarding communications in NSW rail operations and within RailCorp.Following the establishment of TfNSW, RailCorp became an operating agency within TfNSW.TfNSW is now the proponent for the DTRS.The primary objectives of the DTRS project are to:Provide continuous radio coverage across the entire electrified rail network;Replace and improve on the current MetroNet communications system;Provide a technology platform for future development of the Automatic Train Protectionsystem; andAdopt best management and administrative practices while complying with the principles ofecologically sustainable development.The DTRS will provide secure and reliable voice and data communications via a GlobalSystems 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 thenetwork and the number of services using it. It will be compatible with communications systemsused by other users of the network, e.g. freight operators.The DTRS will provide 100% radio coverage along approximately 1455 kilometres of theelectrified rail network, including along approximately 70 kilometres of tunnel and has anexpected design life of at least 15 years.The DTRS will include:A main switching centre at a CBD location;A geographically separated back-up switching centre at Homebush;On-train equipment in approximately 675 train cabs;About 250 base transceiver stations (BTS) as well as other base stations in tunnels;Approximately 65 dispatcher terminal units; andCapability to provide staff with handheld terminals.Page 7 of 75

The DTRS will provide continuous radio coverage across the entire electrified rail network foron-train radios and permit at least 14 simultaneous voice calls from each base station.DTRS systems are now widely used as a standard by major rail operators in Europe and Asia.In Australia, GSM-R is being installed on the Melbourne train network by the VictorianGovernment.1.2 Background to the Hurstville West Portal siteThe proposed distributed base station (DBS) at Hurstville West Portal is part of the DTRS that isbeing developed across the electrified rail network. The proposal at Hurstville West Portal is fora new outdoor DBS site within the railway corridor, associated facilities at Hurstville Station andwithin the Hurstville Apparatus Room, which together will provide coverage along a section oftrack between the east and west end portals of the Hurstville Station Tunnel and partially on thewestern side of Outdoor Location 2 along the Eastern Suburbs and Illawarra Line.A DTRS site has been previously assessed and approved at Outdoor Location 1 at Hurstville;hence Outdoor Location 1 at Hurstville will not be discussed in this REF.The Hurstville West Portal DBS is one of about 250 radio facilities which will provide anenhanced, efficient and reliable communication system for the electrified railway network.1.3 Location and Land UseSite NameStreet AddressProperty DescriptionRailway LineHurstville West PortalIn the rail corridor, off Forest Road via the station car parkaccess road Hurstville NSW 2220Eastern Suburbs and Illawarra LineEastern Suburbs and Illawarra LineChainage 15+924Site Co-ordinatesOutdoor Location 2Local Government AreaNSW State ElectorateCatchmentNearest Railway StationLatitude: -33.966316Longitude: 151.100776Reference system: GDA94Hurstville City Council (near border of Kogarah City Council)OatleyGeorges River (Oatley Bay Subcatchment)HurstvillePage 8 of 75

The proposed DBS site at Outdoor Location 2 is on the northern side of the rail corridor about130 metres northwest of Hurstville Station (refer Figure 1 and Figure 2). The site is in a clearedgravel area about 10 metres from the railway line (refer Figure 3).The site is within the Hurstville Local Government Area (LGA) and the proposed work will beundertaken on land in Zone No.3 (b) – City Business Centre.Land around the Outdoor Locatio 2 site is used for the purposes listed below.• To the northwest and east continues the rail corridor, then Forest Road which runs parallelto the railway line. Beyond are businesses along the major roads, and residential dwellingsbeyond.• A Baptist Union of New South Wales church is 177 metres north, The Church of ChristHurstville is 220 metres northeast, and the Hurstville Presbyterian Church is 320 metresnortheast. The Salvation Army 260 metres northwest and the Church of the Living God is340 metres northwest.• To the south is the railway line and corridor, a small area of businesses and denseresidential development beyond that. The nearest residential receiver to Outdoor location 2is approximately 80 metres southwest.• To the east is the Hurstville Pre-School and Occasional Care Centre within the Westfieldshopping centre, approximately 330 metres away on the corner of Park Road and CrossStreet.• There are no hospitals or aged care facilities located within 500 metres of the proposedsite.There is adequate vehicle and plant access to the site through the existing railway gates off thestation car park access road from Forest Road.Hurstville Railway Substation, located approximately 50 metres northwest of the proposedOutdoor Location 2 site, is a heritage item listed on the Hurstville Local Environmental Plan(LEP) and RailCorp S170 Heritage Register. O’Briens Estate Urban Conservation Area,Hurstville, listed on the non-statutory Register of the National Estate as an Indicative Place islocated on the opposite side of railway tracks approximately 40 metres to the south. TheHurstville Hotel and Belmonte’s Pizza Shop are both locally listed heritage items and are 65metres and 106 metres away to the north, respectively.A few clusters of mature trees line the southern side of the rail corridor along Waniora Street.The proposed works are wholly within the rail corridor. The closest waterway is Poulton Creeklocated roughly 1 kilometre to the southwest and is part of the Georges River catchment.Page 9 of 75

2 Statutory Position and RequirementsThe description of the proposed works and the associated environmental impacts has beenundertaken in the context of Clause 228 of the Environmental Planning and AssessmentRegulation 2000 (EP&A Regulation), the Threatened Species Conservation Act 1995 (TSC Act),and the (Commonwealth) Environment Protection and Biodiversity Conservation Act 1999(EPBC Act). In doing so, this REF helps fulfil the requirements of Section 111 of theEnvironmental Planning and Assessment Act 1979 (EP&A Act), that TfNSW must examine andtake into account, to the fullest extent possible, all matters affecting or likely to affect theenvironment by reason of the activity. The legislative framework relevant to the proposed worksand associated approvals is set out in the following sections.2.1 Environmental Planning and Assessment Act 1979The proposal comprises an ‘activity’ for the purposes of Part 5 of the EP&A Act. As thedetermining authority for the purposes of Part 5 of the EP&A Act, TfNSW must examine andtake into account to the fullest extent possible all matters affecting or likely to affect theenvironment by reason of that activity, in accordance with Section 111 of the EP&A Act.To document TfNSW’s considerations under Part 5 of the EP&A Act, TfNSW is required toprepare a Review of Environmental Factors (REF), which includes mitigation measures tomanage and minimise impacts on the environment. The REF document will be exhibited andmade publicly available. During the exhibition period, the community are encouraged to makesubmissions to TfNSW on the proposal and potential environmental impacts.Prior to determining whether or not to proceed with the project, TfNSW will consider issuesraised in submissions and respond to community feedback. TfNSW may propose changes tothe proposal and detail these in the determination report. The determination report would bemade available to the public on the TfNSW website (www.transport.nsw.gov.au/projects).Should TfNSW determine to proceed, the proposal would be constructed and operated inaccordance with the mitigation measures proposed in the REF, determination report andconditions of approval.Page 15 of 75

2.2 State Environmental Planning Policy (Infrastructure) 2007The ISEPP provides a consistent planning regime for infrastructure and the provision ofservices across NSW, along with providing for consultation with relevant public authoritiesduring 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 whatland the activity is permissible.Section 76 of the EP&A Act states that “if an environmental planning instrument provides thatspecified development may be carried out without the need for development consent, a personmay carry the development out, in accordance with the instrument, on land to which theprovision applies.” However environmental assessment of the development may neverthelessbe required under Part 5 of the EP&A Act.2.3 Confirmation of Statutory PositionClause 79(1) of the ISEPP provides:“Development for the purpose of a railway or rail infrastructure facilities may becarried 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, antennasand power and DBS cabinets), which is consistent with the definition of a rail infrastructurefacility under Clause 78, which includes “signalling, train control, communication and securitysystems”.In addition Clause 114(1) provides:“Development for the purposes of telecommunications facilities (including radiofacilities) may be carried out by a public authority without consent on land.”The proposal also meets the definition of a telecommunication facility under Clause 113 of theISEPP. TfNSW is classified as a public authority under Section 4 of the EP&A Act.Accordingly, this proposal (construction of a new DBS at Hurstville West Portal) is beingassessed under Part 5 of the EP&A Act. TfNSW is the proponent and determining authority asper the provisions of Section 110 of the EP&A Act.Page 16 of 75

2.4 Other Relevant Environmental Planning InstrumentsState Environmental Planning Policy No. 14 Coastal WetlandsThe proposed site is not located within an area covered by this SEPP and therefore no furtherconsideration of SEPP 71 is required.State Environmental Planning Policy No. 19 Bushland in Urban AreasThis SEPP protects and preserves bushland within certain urban areas, as part of the naturalheritage or for recreational, educational and scientific purposes. Hurstville LGA is listed inSchedule 1 as an area where bushland needs to be preserved. However, the proposed workwill not require the removal of native vegetation, so no further consideration of this SEPP isrequired.State Environmental Planning Policy No. 26 Littoral RainforestsThe proposed site is not located within an area covered by the SEPP and therefore no furtherconsideration of SEPP 26 is requiredState Environmental Planning Policy No. 44 – Koala Habitat ProtectionThe proposed site is not in an LGA nominated or classified by this SEPP as habitat for koalas,and is, therefore, not subject to the provisions of SEPP 44.State Environmental Planning Policy No. 55 – Remediation of LandSEPP 55 provides for a consistent state-wide planning approach to the remediation ofcontaminated land. The policy states that land must not be developed if it is unsuitable for aproposed use because it is contaminated. If the land is unsuitable, remediation must take placebefore the land is developed. If contaminated land is encountered during the construction worksa suitable remediation plan will be developed, if required.State Environmental Planning Policy No. 71 – Coastal ProtectionThe proposed site is not located within an area covered by this SEPP and therefore no furtherconsideration of SEPP 71is required.State Environmental Planning Policy (Major Development) 2005This SEPP identifies certain developments which are deemed major projects. The proposal isnot listed in this SEPP.State Environmental Planning Policy (State and Regional Development) 2011The proposal is not listed in the SEPP and has not been declared as State SignificantInfrastructure or State Significant Development under the SEPP.State Environmental Planning Policy (Sydney Drinking Water Catchment) 2011The site is in the Georges River catchment and is not part of a drinking water catchment. ThisSEPP does not apply to the proposal.Page 17 of 75

Hurstville City Council Local Environmental Plan 2012The proposed site is in the Hurstville LGA and is subject to the Hurstville Local EnvironmentalPlan 2012 (Hurstville LEP). The proposed works will be undertaken in the rail corridor, and is inZone No.3 (b) – City Business Centre.Development for the purposes of public utility undertakings is permissible without consent underClause 9 - Table of the Hurstville LEP.As the ISEPP overrides the development consent requirements of any LEP, the proposal canproceed without development consent (refer Section 2.2 for more detail and Section 2.3 formore detail).2.5 Other NSW LegislationCrown Lands Act 1989The proposed work will not be undertaken on crown land and the provisions of this Act are notapplicable to the proposal.Electricity Supply Act 1995The Electricity Supply Act 1995 and Electricity Supply (General) Regulation 2001 set out certainnotification and procedural requirements in relation to excavation.Section 63Z provides:(1) A person must not commence to carry out excavation work to which this sectionapplies, or authorise such excavation work to be commenced, unless the person hasfirst:(a) contacted the designated information provider and requested information as to thelocation and type of underground electricity power lines in the vicinity of the proposedwork, and(b) complied with reasonable procedures of the designated information provider as tothe manner of contacting the designated information provider and the information to beprovided 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 adistribution network service provider, is excavation work to which section 63Z of the Actapplies…(b) excavation that is, or is carried out in connection with, an activity within the meaningof Part 5 of the Environmental Planning and Assessment Act 1979.Page 18 of 75

Consultation with the relevant service provider will occur in accordance with these provisions.Heritage Act 1977Section 57(1) of the Heritage Act 1977 lists the types of activities/works that require approvalfrom the Heritage Council when working on/in an item/place listed on the State HeritageRegister. An application for an exemption can also be made under some circumstances.Approval from the Heritage Council is also required under Section 139 of the Heritage Act 1977prior to the disturbance or excavation of land if a project will, or is likely to result in, a relic beingdiscovered, exposed, moved, damaged or destroyed.The proposed work will not be undertaken within or close to state listed heritage items.Therefore approval under the Heritage Act is not required. More information about heritage isincluded in Section 4.6.National Parks and Wildlife Act 1974The excavating, moving or exhibiting of Aboriginal objects requires a permit under Section 87 ofthe National Parks and Wildlife Act 1974 (NPW Act). The harming or desecrating of Aboriginalobjects or places is an offence under Section 86 of the NPW Act. Under Section 90, anAboriginal 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 siteand no known items or places will be affected by the proposed work. Further, the likelihood ofuncovering Aboriginal heritage items is considered low (refer Section 4.6). Safeguards havebeen proposed to address circumstances if an unexpected find occurs.All native birds, reptiles, amphibians and mammals, except the dingo, are protected in NSWunder the NPW Act. The harming of protected fauna is prohibited under the NPW Act, but anexemption applies in relation to things that are essential to the carrying out of an activity towhich Part 5 of the EP&A Act applies and where the determining authority has complied withthe provisions of that part. Potential impacts to fauna are considered in Section 4.4.Protection of the Environment Operations Act 1997The Protection of the Environment Operations Act 1997 (POEO Act) provides a licensingframework for certain activities as defined in Schedule 1 of the POEO Act. The proposal is notconsidered to fall within the definition of Section 33 ‘Railway systems activities’ of Schedule 1.As such, the proposal does not require an environment protection licence (EPL) under thePOEO Act.Roads Act 1993Under Section 138 of the Roads Act 1993, a person must not “erect a structure or carry out awork in, on or over a public road, or dig up or disturb the surface of a public road...” other thanPage 19 of 75

with the consent of the appropriate roads authority. However, clause 5(1) in Schedule 2 of theAct states that public authorities do not require consent for works on unclassified roads.The proposal does not require any work to be undertaken in, on or over a classified road.Therefore, approval from Roads and Maritime Services (RMS) will not be required.Threatened Species Conservation Act 1995The Threatened Species Conservation Act 1995 (TSC Act) is directed at conserving threatenedspecies, populations and ecological communities of animals and plants. Based upon desktopsources, threatened species, populations, endangered ecological communities are not likely tooccur at the site and further consideration under the Act is not required.Native Vegetation Act 2003The Native Vegetation Act 2003 (NV Act) manages the clearing of native vegetation in NSW.Section 25(g) of the NV Act provides that any clearing that is part of an activity that ispermissible without consent does not require approval under the Act.Nevertheless, RailCorp’s guideline for the vegetation management in rail corridors provides aframework for compliance with this Act.The proposed works do not include native vegetation clearing and therefore provisions of theAct do not apply.2.6 Commonwealth LegislationEnvironment Protection and Biodiversity Conservation Act 1999The primary legislation at the Commonwealth level is the Environment Protection andBiodiversity Conservation Act 1999 (EPBC Act). Part 3 of the EPBC Act requires approval fromthe Commonwealth Minister for Sustainability, Environment, Water, Population andCommunities if a development is likely to have, or will have, a significant effect on a matter ofNational 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.Page 20 of 75

The proposed work will not affect matters of national environmental significance.Commonwealth land will not be affected, either directly or indirectly, as a result of this proposal.Consideration of the EPBC Act factors is included in Table 4 in Section 4.19.Commonwealth Telecommunications ActTo operate the DTRS, TfNSW will have a Telecommunication Licence and so will have certainrights under the relevant Commonwealth Legislation. In particular, TfNSW will be able to installlow impact facilities without reference to local or state approvals processes.However, the Telecommunications (Low-impact Facilities) Determination 1997 defines a lowimpact facility as:Panel, Yagi or other like antenna:(a)Not more than 2.8 metres long; and(b) If the antenna is attached to a structure — protruding from the structure by not more thanthree metres.Since this DTRS site includes the installation of a pole greater than three metres, it is not a lowimpact facility and so will be assessed under Part 5 of the EP&A Act.2.7 Ecologically Sustainable DevelopmentEcologically sustainable development (ESD) entails using, conserving and enhancing thecommunity’s environmental resources in a manner that sustains and improves ecologicalprocesses and, hence, the quality of life for present and future generations. The basis forachieving ESD involves the application of four principles:the precautionary principle;intra- and inter-generational equity;conservation of biological diversity and ecological integrity; andimproved valuation and pricing of environmental resources.TfNSW is committed to ensuring its projects are consistent with the principles of ESD and thesehave been considered for this proposal (refer Table 1).Table 1Consideration of ESD for the proposalESD PrincipleApplication to the proposalPrecautionary principleThe site selection and design process aims to avoid areas wherethere will be a significant environmental impact or impacts that areirreversible. The site selected is within a previously disturbed areain the rail corridor. In addition, some of the potential impacts arereversible as the monopole, cabinets and Yagi antennas can bePage 21 of 75

ESD PrincipleApplication to the proposalremoved if no longer required.Adverse impacts associated with the site and construction will beminor and measures to reduce impacts identified within this REFwill be implemented during construction.Intergenerational equityConservation ofbiological diversity andecological integrityImproved valuation andpricing of environmentalresourcesThis proposal and the overarching DTRS project will contributetowards TfNSW’s strategic benefits for current and futuregenerations, including safer public transport, by improving on thecurrent communications system, providing coverage and reliablecommunications services to all parts of the electrified rail networkand acting as the basis for the introduction of an Automatic TrainProtection System.The economic, social and safety considerations of the DTRS havebeen integrated with the consideration and assessment ofpotential environmental impacts regarding the development andoperation of the DTRS.The proposed site is on disturbed land that has been previouslycleared. Major clearing or other disturbance to the biodiversity oritems of ecological significance of the area is not required. Theproposed activity is not expected to result in loss of biodiversity orecological integrity.TfNSW recognises the value of environmental sustainability andwill minimise the impact of its activities by ensuring appropriatemitigation measures are implemented for all aspects of the DTRSproject.

It will be subjected to additionalapproval.These components are described in the sections below. Plan drawings are provided inAppendix 2. All aspects of the proposal will be earthed in line with all relevant standards.Page 23 of 75

3.1.2 DBS SiteDTRS CabinetThe DTRS cabinet will be placed within the Apparatus Room (Equipment Location 4) 40 metresnorth-west of Outdoor Location 2. The cabinet will be approximately 1855 millimetres high by600 millimetres long by 450 millimetres wide, and will be placed on a steel plinth with aminimum height of 200 millimetres to allow for the management of cables entering the cabinet.The DTRS cabinet will include the following equipment:Direct current (DC) distribution (including electromagnetic interference filter and surgeprotection);Transmission interface (Huawei PTN910);Fibre optic distribution frame; andMonitoring and reporting capability of power cabinet conditions (Media Converter).DBS/Power cabinetThe DBS power cabinet will be placed on the end of Platform 3 and 4 of Hurstville Station(Equipment Location 3). The cabinet will be approximately 1700 millimetres high by 1000millimetres long by 880 millimetres wide. It will be placed on a steel plinth with a minimumheight of 200 millimetres to allow for the management of cables entering the cabinet. The powersupply will enter the cabinet via conduit located at the rear of the cabinet.The cabinet will consist of the following:Alternating current (AC) and earth terminations;A transfer switch (mains and generator positions);Surge protection;A general purpose outlet;A low voltage disconnect;Rectifier modules;A controller/supervisory module;Ethernet Media Converter to accommodate optical fibre transfer of supervisory information;A DC distribution rack;Optical Distribution Frame for fibre optical fibre connections;RF field monitoring devices;48V-12V DC-DC converters;A socket inlet for external generator input is provided in case of mains failure; andPage 24 of 75

Batteries (with the capability of providing a minimum of 12-15 hours’ back-up).MonopoleA 10 metre monopole will be erected in the rail corridor approximately 10 metres from thenorthern side of the track (Outdoor Location 2). Two Yagi antennas will be mounted 9 metresabove the ground with azimuths of 125° and 300°. The antennas will be installed to have a zerodegree tilt, but will be able to be remotely adjusted to different degrees of tilt, without the needto climb the monopole for such adjustments.3.1.3 Power SupplyThe proposed power supply is yet to be confirmed. It will be subjected to additional approval.3.1.4 Fibre OpticsOptical fibre will run in a new trench (approximately six metres long) from the Outdoor Location2 monopole to an existing pit, and then via existing cable routes to the new DBS/power cabinetat the end of Platform 3 and 4.Optical fibre will run through the existing cable route from the DTRS cabinet inside HurstvilleApparatus Room to the existing pit near the end of the Platform 3 and 4. Then approximatelyseven metres trenching will be required for the fibre to connect from the existing pit to theDBS/power cabinet and RRU at the end of the Platform 3 and 4.3.1.5 EarthingThe earthing installation will comprise six earth stakes at a pre-determined distance apart. Oncethese earth stakes have been installed, the system will be tested and modified if needed. Theinitial extent of the trenching for earthing grid will be around 20 metres. However, it can beextended up to five metres if the results show that the earthing arrangement is insufficient.3.2 Construction MethodologyConstruction of the DBS facility will require the use of approximately 60 square metres of land atOutdoor Location 2 and 20 square metres of land at Equipment Location 3 within the railcorridor. This area will allow for the monopole and DTRS cabinet to be installed.The monopole foundation will require an excavation approximately five metres deep with adiameter of one metre. This will result in approximately five cubic metres of excavated materialwhich may include rock.Installation of the fibre optic cables will require excavation of trenches approximately 1000millimetres maximum depth and 500 millimetres wide.The indicative construction methodology of the facility will include elements outlined below.Non-destructive excavation before construction to establish underground installations.Site establishment.Page 25 of 75

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 concrete slab brought to site for 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 monopole sections using trucks and riggers.Assembly of monopole and attachment of antenna mounts and cables before erection ofthe 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 facilityto the electrical supply and optical fibre communications cable.Installation and commissioning of radio equipment, batteries, antennas, cables and otherequipment.Materials used for construction and installation include concrete, gravel, a steel plinth, steelmounts, antennas, batteries, cables and radio equipment. It is not envisaged that chemicals orhazardous materials will be used during construction.The majority of material brought to the site will remain there once installed. Excess material willbe removed and reused, recycled or disposed of. Any excess concrete will be removed. Allexcavated material not required for backfilling will be stockpiled, removed from site anddisposed of at a licensed facility or used elsewhere on the site.The following equipment will potentially be used during construction.Pile borerHiab truck 10TTrencher (chain digger)ExcavatorsBobcatVacuum excavator (Sucker Truck)Wacker packerEarth rod drillConcrete delivery truckPage 26 of 75

Delivery truck VLC (semi-trailer)1.5 tonne come-a-long17 metre slingAssorted slings and shacklesAssorted large spanners and hand toolsHydraulic pack and ramPortable generator (with RCD)Cable stripping toolsHydraulic hole punch (sized to suit cable gland)Crimpers ratchet typeBattery drillMultimeterElectrical hand toolsHand digging tools (shovels etc.)The skip bin and site compound area will be located within the rail corridor near the site ifrequired. The construction process will require an average of four to six vehicle movements anda team of three to six people on site per day.3.3 Timing and CostingConstruction is planned to begin mid 2013 and construction activities will require four to sixweeks. The bulk of work may require to be undertaken in non-consecutive work days.Proposed construction timing:Standard working hoursEvening/weekends/out of hours:Monday to Friday 7.00am to 6.00pmSaturday 8:00am to 1:00pmNight work from 8:00pm to 4:00am is required forcable connection and antenna installation work atHurstville Station.The DTRS project has an overarching value of $225 million. This includes the design, supply,and installation of the DTRS on the electrified rail network plus a five-year life supportcomponent.Page 27 of 75

3.4 Alternatives to the DTRSA number of alternatives already used by the state government or available commercially wereinvestigated. The government alternatives were the existing MetroNet system or theGovernment Radio Network (GRN).The existing MetroNet communication system was not deemed a feasible solution for thereasons 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 costof 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 TfNSWpersonnel.It could not meet interoperability requirements.The Department of Commerce’s Government Radio Network (GRN) was not deemed a feasiblesolution 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% radiocoverage across the rail network.The network is both inside and outside the rail corridor.GRN would require a substantial upgrade, including new base stations, to ensure 100%radio coverage across the rail network.The cost of this upgrade is comparable to the development of an entire new network.The radio communications marketplace responded with three systems: APCO-25, TerrestrialTrunked Radio (TETRA) and GSM-R.APCO-25 is a proven standard for emergency services but was rejected for the reasons listedbelow.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 mobilesubscribers’ 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 reliability requirements.It is not scalable in regard to the future growth of the rail network.Page 28 of 75

TETRA is also a proven emergency services communications system and is deployed in anumber metropolitan rail networks. However, it was rejected for the reasons listed below.This application is confined primarily to underground metro networks that are notcomparable to the electrified rail network.It relies on a dispatch terminal for functionality, which does not meet reliability requirements.It does not meet the interoperability requirements.There is no commercialised Automatic Train Protection solution available.GSM-R was deemed the platform most suitable for the electrified rail network and systemrequirements for the reasons listed below.It is the only rail-specific communications standard and has the highest levels of safety andreliability in its design.It is an open standard with a large number of equipment suppliers.It achieved a higher level of compliance with the functional requirements when compared tothe other systems.It is deployed by major rail operators in Europe and Asia, some with networks comparablein size and complexity to the electrified rail network.It operates on a spectrum of 1800 MHz which was available for purchase by TfNSW. Theother options would have required the leasing of a radio spectrum from atelecommunications licence holder.It is a scalable network that can grow in step with the electrified rail operations and network.It is compatible with the Australian Rail Track Corporation’s communication system.It provides a platform for future enhancements and increased operational safety, including aLevel 2 Automatic Train Protection System, as per the recommendations of the Waterfallinquiry.It will deliver the best value for money solution with the least risk.3.5 Alternatives to the Hurstville West Portal siteThe following options were considered for the development of the Hurstville West Portal site:• To do nothing; or• Install the antennas on existing communication facilities in the Hurstville area.The do nothing option was rejected for the reasons listed below.• The inability to meet the requirement of 100% radio coverage across the electrified railnetwork.Page 29 of 75

• A ‘black spot’ in the DTRS network, resulting in a significant safety issue in the event of anemergency call or a train incident.• The increasing maintenance costs of the MetroNet facility and the limited reliability foradequate operation for the next 10 – 15 years.None of the existing communications facilities were in a suitable position or offered the requiredheight to provide adequate coverage to the rail network, and as such were not selected for thisproposal.Other infrastructure options were considered, but were not feasible for the proposal.• The proposed monopole is less obtrusive, requires less space and will be cheaper tomaintain than a lattice tower or guyed mast. A monopole also uses a foundation designthat is better suited given the spatial limitations within the rail corridor. The monopole isthinner at the top and less obtrusive than a lattice tower, helping to minimise the visualimpacts of the proposal.• The monopole can be installed using a hinge mechanism, which removes the need forlarge cranes.The installation of a walk-in equipment hut would use more space and be more expensive. Theuse of outdoor cabinets was the most suitable solution given the limited space, cost andminimisation of environmental impacts.Radio frequency modelling also indicated that a new DBS further west of Hurstville Stationwould not provide adequate coverage to the rail corridor.3.6 Justification of the Preferred OptionIt was decided to construct a DBS at the proposed location because it will enable the site to beconsistent with the whole DTRS network. Consistent technology choice will enable TfNSW toimprove its existing quality of service, reliability and emergency responsiveness. The reasonsfor selecting the technology are discussed above.The Hurstville West Portal site was selected due to its ability to cover the section of trackbetween Carlton and Penshurst. The proposed antenna height of nine metres is the minimumheight required to provide optimum radio frequency coverage for these sections of trackThe proposed site is also close to existing fibre and has good construction and maintenanceaccess. The proposed work will not require the removal of native vegetation.The proposed Outdoor Location 2 is located near the Apparatus Room west of the station. Thesite accommodates the equipment, has ready access without the need for scheduled trackpossession and provides a local power source.Page 30 of 75

In summary, a higher pole, or an additional DTRS facility would be required if the site was to berelocated. It was decided that the preferred option would offer the least impact on the localenvironment while still meeting operational requirements.Page 31 of 75

4 Environmental Impact and Risks4.1 Landforms, Geology and SoilsExisting SituationThe proposed site is inside the railway corridor approximately 10 metres north of the railwayline. The proposed DBS site is in a cleared gravel area. The geology comprises WianamattaGroup of black to dark-grey shale and laminite, underlain with Liverpool subgroup of shale withsome sandstone beds. The soil is of the Glenorie soil landscape type, which is comprised ofshallow to moderately deep Red Podzolic Soils, Red and Brown Podzolic Soils, and YellowPodzolic Soils, and has high erosion potential once exposed.NSW Acid Sulfate Soils (ASS) risk mapping provided by the NSW Office of Environment andHeritage (OEH) indicates the proposed site is in an area of no known occurrence and noexpected occurrence of ASS.A geotechnical review has not yet been undertaken for Outdoor Location 2. This review will becompleted prior to construction to anticipate the presence of contaminated material on site andto confirm the site is suitable for the proposed use. Prior to construction UGL will confirm groundconditions by:On-site inspections during pre-construction site reviews to confirm desk-top studypredictions.Potential ImpactsApproximately 60 square metres and 20 square metres will be disturbed at Outdoor Location 2and Outdoor Location 3 respectively during construction of the proposed DBS site. Excavatedsoil and rock will be stockpiled and removed from the site if it cannot be used elsewhere on thesite. The foundation for the monopole will result in about five cubic metres of spoil (not includingtrenching). The trenches for the cables will be backfilled upon completion.Excavation and trenching activities may result in erosion if appropriate mitigation measures arenot in place. Soil erosion has the potential to destabilise landforms and deposit sediments indrainage systems and waterways. Sediment deposition and fine particles in suspension withinwaterways have direct impact on water quality and aquatic life.Given the site characteristics and the scope and size of the proposed work, it is anticipated thaterosion and sediment risks are minimal and can be effectively managed through theimplementation of standard measures as outlined in the Landcom/Department of HousingManaging Urban Stormwater, Soils and Construction Guidelines (the Blue Book) (Landcom2004).No operational impacts are expected.Page 32 of 75

Control MeasuresSite specific Erosion and Sediment Control measures will be identified as part of ECM. Theproposed measures will be in accordance with the ‘Blue Book’ (Managing Urban Stormwater:Soils and Construction 4 th Edition (Landcom, 2004), and will be implemented during theconstruction phase. The measures will include, but not be limited to, those outlined below.All spoil will be transferred directly to skip bins or stockpiled appropriately.Appropriate stockpiling of materials will take place away from drainage lines, waterwaysand drains.Soil that may be contaminated or weed infested will be stockpiled separately before beingremoved 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 shakergrids/ballast pads.Soil will be removed from public roads and other paved areas using dry street sweepers orother measures.Disturbed areas will be reinstated, if required.During maintenance activities, spills will be attended to and treated in an appropriate andtimely fashion in accordance with TfNSW procedures.4.2 Water Quality and HydrologyExisting SituationThe nearest waterway, Poulton Creek (which flows into Oatley Bay), is about one kilometresouthwest of the site and forms part of the Georges River catchment. The suburban stormwatersystem is situated along the main roads (i.e. access driveway off Forest Road) and some drainsmay be close to the construction footprint.Flood mapping for the proposed site location is not provided by Hurstville City Council, howevergiven the locations topography and proximity to waterways, flood risk is considered to be lowPossible RisksThere is a risk that the local underground water table may be reached and groundwater mayappear during pile boring activities. While this is not expected to occur at this site due to thedistance from the site to the nearest body of water, it remains the major risk in respect of waterquality and hydrology. The CEMP and Water Management Plan will contain procedures tomanage this risk if it eventuates.Page 33 of 75

Potential ImpactsIn addition to sediment rich runoff, the following wastewater types can be generated byconstruction activities:Liquid waste from non-destructive excavation;Water from spills;Sewage from the site facilities; andWater collected in trenches and the pit.Without appropriate safeguards, contaminants such as liquid waste generated during nondestructiveexcavation may reach nearby drains and discharge into local waterways. Thesecontaminants may have the potential to harm aquatic life and affect the quality of waterdownstream. However, the risk of such occurrence would be minimised through implementationof measures provided in the control measures listed below.Rain or groundwater may enter the excavations. If inappropriately managed, sediment-ladenwater could be discharged into local water bodies and/or the nearby stormwater system.No operational impacts are expected. The works will not affect the landform or the flow of waterin the area.Control MeasuresDuring construction water quality impacts will be minimised through a range of control measuresin addition to the erosion and sedimentation controls included in Section 4.1. The water qualitymeasures will include, but will not be limited to those outlined below.A Water Management Plan will be prepared before construction begins to determine themost appropriate method for water disposal should groundwater be encountered during pileboring activities.A geological engineer will be present during the boring of the pile and work will ceaseimmediately if groundwater is encountered. The water will be tested according to industrystandards to determine the presence of contaminants or other materials. This will determinethe most appropriate method of water disposal. If water is encountered, special constructionmethodologies will be adopted to prevent a continuing flow of groundwater to the surface.Ensure construction materials are not left in the vicinity of stormwater drains.Trenches and excavations will be covered to prevent rainwater entering.Plant and equipment will be checked regularly for oil leaks.Plant and equipment will not be refuelled on site.Wash down areas will be located away from waterways and drainage lines.Page 34 of 75

Liquid waste generated during non-destructive excavation will be removed from the-site fortreatment and disposal.4.3 Air QualityExisting SituationHurstville City Council’s State of the Environment Report 2009-2010 reported that the regionalair quality in Hurstville was largely ‘good’. Local air quality is influenced predominantly by trafficemissions.Potential ImpactsLocal and regional air quality can be affected during construction by dust, construction vehicleemissions and odour. Dust may be generated from the disturbance of soils or poorly maintainedstockpile areas, which can affect human health or property. Poorly maintained vehicles canproduce 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 anddiesel). Fuel use will emit greenhouse gases with about 2.3 to 2.7 kilograms of carbon dioxideequivalent (CO 2 -e) per litre of fuel consumed (DEWHA 2008). In addition, indirect and thirdparty emissions will be generated as a result of energy used to produce materials (for examplesteel and concrete) – which is known as ‘embodied energy’.During operation, electricity will be required to power the facility, but the energy use will formonly a small contribution to TfNSW’s overall greenhouse gas emissions.Control MeasuresAir quality impacts throughout construction will be minimised through a range of controlmeasures which will include, but will not be limited to, those outlined below.Plant and equipment will be maintained in accordance with manufacturers’ specifications.Regular inspection of plant and equipment will be undertaken to ascertain that fittedemission controls are operating efficiently.Plant or machinery will not be left idling.Stockpiles will be maintained and contained appropriately, which could include covering orregular watering to minimise dust.Trucks transporting spoil and other waste materials from site will be covered appropriately.Disturbed areas will be rehabilitated as soon as practicable.Page 35 of 75

4.4 BiodiversityExisting SituationBased on a search within a one kilometre buffer of the proposed site, there are 21 species offauna, nine species of flora, 14 migratory bird species, and two threatened ecologicalcommunities are listed as threatened under the Environment Protection and BiodiversityConservation Act 1999 (EPBC Act). These species or their habitat may occur in the search area(refer Appendix 3). Based on a search within a 10 kilometre buffer of the proposed site, thereare recordings of 102 threatened fauna species, 56 threatened flora species and 24endangered ecological communities listed under the Threatened Species Conservation Act1995 (TSC Act) within the search area (refer Appendix 3). State mapping indicates that theSuperb Fruit-dove (threatened species in NSW) has been sighted approximately 140 metresnorth of Outdoor Location 2.The immediate area around the site has been cleared previously. There is an area of maturetrees along the southern side of the rail corridor along Woniora Road. RailCorp IllawarraVegetation Mapping - Allawah to Hurstville does not identify flora or fauna in the vicinity of thesite that require specific protection measures.RailCorp Sensitive Site Register did not identify sensitive areas close to the proposed site.There are 89 species of noxious weeds identified in the Hurstville LGA. Weed control isenforceable by Hurstville City Council, as the local control authority under the Noxious WeedsAct 1993. RailCorp vegetation mapping also indicates that Blackberry and Olive are found onthe proposed site.Potential ImpactsWhile there are threatened species known to be present in the searched area, the site is in adisturbed area within the rail corridor, an area where there is no bushland or dense vegetation.Threatened species Superb Fruit-dove has been sighted 140 metres to the north of Location 2however the sighted location is a busy carpark and only one known sighting has been recorded.It is therefore unlikely that there is a nesting area near the sighted location. No impact to thethreatened species is expected.The works are not expected to impact on listed threatened species or threatened ecologicalcommunities. Given the absence of suitable habitat, it is unlikely that threatened fauna specieswill be present in the area.As such, the proposed works will not affect, threaten or have a significant impact on ecologicalcommunities, plants or animals listed under the EPBC Act and/or TSC Act. Referral to theCommonwealth Minister for Sustainability, Environment, Water, Population and Communitiesfor further consideration or approval in relation to potential flora and fauna impacts associatedwith the works is not considered necessary. Similarly, the preparation of a Species ImpactPage 36 of 75

Statement under NSW legislation to further consider the impacts of the proposal on threatenedplants or animals is not considered necessary.Excavation work has the potential to affect nearby trees if roots are damaged during excavationor equipment collides with trees. The nearest trees are about 20 metres from the site, whichshould be a sufficient distance to avoid adverse impacts.No native vegetation will be removed however some grass will be cleared.Once soil has been disturbed there is the potential for the spread of weeds. Noxious weeds areknown to occur in the Hurstville area.With regard to fauna, the work will not remove native vegetation or other features considered aspotential habitat for fauna (threatened or otherwise). Animals could potentially fall into an opentrench and become trapped or injured. Trapped animals could be accidentally entombed duringthe backfilling of trenches.No operational impacts are expected.Control MeasuresImpacts on flora and fauna throughout construction will be minimised through a range of controlmeasures which will include, but will not be limited to, those outlined below.If threatened flora or fauna species are identified on site, work will stop immediately. Aspotter/catcher or botanist will be engaged to survey the site, in conjunction with TfNSW’sEnvironmental Officer, and advise on species managementNo native vegetation will be removed.Root cutting will be avoided.Care will be taken to minimise the spread of weeds. Appropriate management and disposalof noxious weeds will be undertaken in consultation with Hurstville City Council, if required.The work site will be inspected for trapped or injured fauna at the start of each day.Trenches/excavations will be covered at the end of each day and inspected before they arebackfilled to ensure that no fauna species are harmed.4.5 Noise and VibrationExisting SituationThe adjacent railway line and local traffic are the major sources of noise in the area.The closest residential receivers to the Outdoor Location 2 site are residents on Woniora Roadapproximately 80 metres southwest of the proposed site. Other receivers include the BaptistUnion of New South Wales church, The Church of Christ Hurstville, Hurstville PresbyterianChurch, Salvation Army, Church of the Living God and Hurstville Pre-School and OccasionalCare Centre within the Westfield shopping centre (refer Section 1.3 for more information). ThePage 37 of 75

other receivers are the Hurstville Station commuters and commercial businesses approximately25 metres away.Construction NoiseThe Interim Construction Noise Guideline (ICNG) (DECC 2009) defines noise managementlevels (measured in decibels) for residential receivers and other types of receivers includingcommercial and industrial premises, places of worship and schools.The ICNG states:Where the predicted or measured L Aeq, 15 min is greater than the noise affected level, theproponent should apply all feasible and reasonable work practices to meet the noiseaffected levelThe proponent should also inform all potentially affected residents of the nature of works tobe carried out, the expected noise levels and duration and contact detailsFor works above the highly affected noise criteria, respite periods may be required, and forworks outside standard hours there needs to be a strong justification and negotiation withthe community (DECC 2009).Noise associated with the proposal is likely to be generated by construction trucks, machineryand, in particular, boring activities required to establish the foundations for the monopole. Theseactivities will be of a short duration.Construction is expected to take six weeks and all work is expected to be undertaken duringstandard working hours. The key noise-generating activity, the pile boring, is expected to beundertaken during one day.Given this, background noise monitoring and the establishment of noise management levels forsensitive receivers is proposed. A qualitative construction noise assessment has beenundertaken (refer Table 2).In addition, the ICNG prescribes a highly noise affected criteria of 75 dBA L Aeq, 15min, at nearbyresidential receivers which is the point at which there may be strong community reaction tonoise. Given the offset distance, it is unlikely that sensitive receivers will experience a noiselevel above the highly affected level of 75 dBA L Aeq, 15min during the noisiest works.Page 38 of 75

Discomfort effects are not expected given the types of machinery required for constructionworks. Similarly, structural damage to buildings is not expected as the nearest buildings areadjacent to the railway and already experience vibration from trains on a regular basis.Operational Noise and VibrationNo operational impacts are expected.Control MeasuresConstruction works will adopt Best Management Practice (BMP) and Best Available TechnologyEconomically Achievable (BATEA) practices as described in the Interim Construction NoiseGuideline (ICNG) (DECC 2009) and be carried out in accordance with TfNSW’s ConstructionNoise Strategy.Control measures to minimise noise and vibration impacts will include, but will not be limited to,those outlined below.Maximise the offset distance between noise plant items and sensitive receiversOrient plant and equipment away from sensitive receiversAvoid the simultaneous operation of two or more noise plant items in close vicinity andadjacent to sensitive receiversCarry out loading and unloading away from sensitive receiversWhere necessary, use structures to shield sensitive receivers from noise sourcesProvide periods of respite if high noise generating activities occur for extended periods.In addition, the community will be notified of the works and their duration and provided withcontact details before work begins. Any noise complaints received will be addressed by theProject Manager as soon as possible.4.6 HeritageExisting SituationA search for non-Aboriginal heritage items was completed by consulting the followingdatabases: Hurstville LEP and Kogarah LEP, State Heritage Register, State Heritage Inventory,Australian Heritage Database, (including Commonwealth Register of the National Estate), worldheritage sites and RailCorp’s Section 170 Heritage and Conservation Register.There are some heritage items around the proposed area (refer Appendix 3). They include:• Hurstville Railway Substation is a local and RailCorp S170 Heritage listed item, and islocated approximately 40 metres northwest of the proposed DBS site on the accessdriveway off Forest Road.Page 41 of 75

• O’Briens Estate Urban Conservation Area, Hurstville is listed on the non-statutory Registerof the National Estate as an Indicative Place. The area is located on the opposite side ofrailway tracks, approximately 40 metres south of proposed DBS site.• The Hurstville Hotel is a locally listed heritage item and located approximately 65 metresnorth of the proposed DBS site on Forest Road.• Belmonte’s Pizza Shop is a locally listed heritage items and located approximately 106metres north of the proposed DBS site on Forest RoadA search for known items of Aboriginal heritage value was undertaken for the proposed site,(with a 200 metre buffer) using OEH’s Aboriginal Heritage Information Management System(AHIMS). No Aboriginal sites or places were found at the location or its surrounds.Potential ImpactsAll work will be undertaken away from known items and outside the boundaries of heritageitems. The proposed monopole is not expected to interrupt or block views of the heritage listeditems or affect the heritage significance of these items. The works are unlikely to have animpact on known items or places of non-Aboriginal heritage value. No permits or approvals arerequired.The construction works will not impact known items of Aboriginal heritage significance.The potential to uncover unidentified Aboriginal heritage items during construction is low. Thesite is in an area that has been disturbed previously.Control MeasuresImpact on heritage throughout construction will be minimised through a range of controlmeasures, which will include, but will not be limited to, those outlined below.If a non-Aboriginal historical relic is discovered, all work likely to affect it will cease and theProject Manager will be contacted. TfNSW staff and the Office of Environment and Heritagewill be notified as required. An investigation will be undertaken by a suitably qualifiedarchaeologist to identify suitable measures to reduce the impact on the relic discoveredbefore work resumes.Should Aboriginal heritage items be uncovered, all work in the vicinity will cease and theProject Manager and TfNSW staff will be notified immediately. The OEH will be notified inaccordance with the National Parks and Wildlife Act 1974. The Local Aboriginal LandCouncil will be notified and an assessment by an archaeologist will be arranged todetermine the significance of the objects and other requirements before work resumes.4.7 WasteOverviewPage 42 of 75

TfNSW is required to manage waste in accordance with the Waste Avoidance and ResourceRecovery Act 2001 (WARR Act). The waste hierarchy (Avoid, Reuse, Recycle, EnergyRecovery and Disposal) should be followed for all projects.Potential ImpactsThe main waste streams that may be generated during construction include:Spoil from excavation;ConcreteAsphalt;Vegetation;Packaging;General litter including glass, plastic, metal and paper waste;Wiring; andWastewater from non-destructive excavation.No operational impacts are expected.Control MeasuresA Waste Management Plan will be prepared as part of the CEMP to detail waste types andquantities as well as methods for segregation, handling, storing and disposal. Furthermore,waste impacts will be minimised through a range of control measures, (consistent with theWARR Act) which will include, but not be limited to, those outlined below.All waste will be classified in accordance with the Waste Classification Guidelines (DECC2009) and transported to a place that can lawfully accept the waste.Material that may be classified as a hazardous waste will be dealt appropriately and inaccordance with TfNSW procedures.Packaging will be minimised, where possible and where the safety and delivery of servicesis not compromised.Wherever possible, suitable excavated spoil will be reused on site for backfilling,landscaping and other purposes.Spoil or waste material tracked onto roads will be swept up immediately.Adequate numbers of bins and waste containers will be placed at the site. The site managerwill ensure bins are not overflowing and are appropriately covered.Waste water generated by non-destructive excavation will be taken off site for treatmentand disposal.Page 43 of 75

All waste will be removed from the site when work is completed.4.8 Contaminated LandExisting SituationAn initial investigation has been carried out for potential land contamination. The investigationincluded:A visual inspection for signs of potential land contamination;A search of the NSW Environmental Protection Authority (EPA) register of contaminatedsites;A search of RailCorp records; andA review of all materials to be used at the site to establish their potential for landcontamination.Due to the historical and ongoing use of the site as part of the rail corridor, the followingpotential sources of contamination may be present in the vicinity of the site:Fuel and oil spills and engine emissionsRail corridor maintenance activities, such as application of pesticides and herbicidesBrake liningsHistorical cables / pipework ducting and former site structures, with potential asbestoscontaining materialsFabric of old rolling stockImported fill.The initial investigation identified signs of potential land contamination close to the proposedsite. A small pile of waste (construction materials including cement bricks, old paint can withsuspected dried cement, low density board and sand material) was observed directly adjacentto the area of proposed construction (refer to Figure 4). No soil discoloration or odours werenoticed.RailCorp does not have any record that the site is contaminated. There are no EPA registeredcontaminated sites near the vicinity of the proposed DBS site.Page 44 of 75

Figure 4Area of potential land contamination adjacent to proposed sitePotential ImpactThe small area of construction waste adjacent to the proposed site within the railway corridorwill be assessed and removed prior to the construction.The limited investigation cannot exclude further potential contamination as the result ofunknown past activities, either on the site or in the vicinity. There is a risk that contaminantscould be encountered during the proposed work. If encountered, contaminants may pose a riskto the health of workers and the environment in general.Control MeasuresThe risk of encountering unknown contaminants during excavation will be managed inaccordance with TfNSW procedures, the CEMP, the ECM and land contamination legislation.Control measures to manage contamination risks will include, but not be limited to, thoseoutlined below.The small area of construction waste adjacent to the proposed site within the railwaycorridor will be assessed and removed prior to the construction.During excavation, site workers will look for signs of potential contamination such as thepresence of waste and/or other imported materials, odours, soil colouring, floating layers ingroundwater etc.If any contamination is encountered, or suspected, the work will be immediately stoped andthe site fenced off. The site will be investigated and validated and work will only resumePage 45 of 75

after approval from HSE Manager is obtained. Contaminated soil will be segregated in aspecial container before classification and disposal.The CEMP will further detail the proposed control measures.4.9 Hazardous MaterialsPotential ImpactsConstruction, operation and maintenance of the proposed facility will not require the use ofhazardous chemicals and/or materials.If not properly used, chemicals may present a risk to the safety of workers and the environmentin general. Safe use of hazardous chemicals is regulated and subject to numerous standards,including a need for a dangerous goods licence.Control MeasuresIf hazardous materials are required for any unforeseen reason, a hazardous wastemanagement plan would be prepared. The plan will detail terms applying to the purchase,storage, use, handling and disposal of such materials.The impact of hazardous materials will be minimised through a range of control measuresincluding, but not limited to, those outlined below.Hazardous materials will be properly classified and managed in accordance withrequirements for their particular class.An evaluation of alternative materials will be undertaken before use of chemicals isapproved.Hazardous materials will be transported, stored and used in accordance with thecorresponding material safety data sheets which will be available on the site.Hazardous materials will be stored in a locked and bundled area at the site; incompatiblechemicals will not be stored together.No fuels will be stored on site. Refuelling will be undertaken at off-site facilities.Adequate spill prevention, containment and response measures (e.g. drip trays) will beprovided on site if needed.Construction personnel will be trained in spill containment and response procedures.All storage and handling equipment on site will be maintained properly.4.10 Visual Aesthetics and Urban DesignExisting SituationPage 46 of 75

The visual landscape surrounding the proposed site includes the Eastern Suburbs and IllawarraLine and associated overhead power lines. There is vegetation lining the southern fence of therail corridor.Residential dwellings are about 80 metres away on Woniora Road.Potential ImpactsDuring construction the visual environment will be temporarily altered through the presence oftemporary work buildings, plant and equipment, such as trucks.While the site is operational, a new 10 metre high monopole will be introduced into the visualenvironment. The DTRS cabinet will be located within the Apparatus Room 40 metres northwestof Outdoor Location 2 and the DBS/power cabinet will be located within the west portal ofthe Hurstville Station Tunnel and will therefore not be visible to the public. The DBS/powercabinet will be located within the portal and surrounded by a retaining wall and will also be outof site of the public. The Yagi antennas that are proposed to be mounted to the west end portalof the tunnel will be of similar colour to the tunnel.A photomontage of the new monopole at Outdoor Location 2 is provided as a guide in Figure 5.Visually sensitive receivers in the vicinity of the site include the residential dwellings on WonioraRoad located approximately 80 metres to the southwest of the site. There are tall commercialbuildings and an area of mature trees that line the railway corridor which will block the view ofthe proposed monopole from these receivers.The new monopole will be 10 metres in height and will be visually similar to the existingoverhead power lines and infrastructure within the railway corridor.The potential visual impact of the proposal is considered to be low.Page 47 of 75

Figure 5View of proposed facility looking west across the rail corridorControl MeasuresVisual impact will be minimised through a range of control measures which will include, but willnot be limited to, those outlined below.The work area shall be maintained in an orderly manner.All temporary signage associated with the works must be appropriately displayed.All work equipment and materials will be contained within the designated boundaries of thework site.All waste generated during the course of the works will be removed from the work areas assoon as practicable or at the end of each work day and disposed of in accordance with themeasures identified for ‘Waste’.On completion of work, all vehicles, materials and refuse relating to the works will beremoved and the site reinstated to the pre-work condition if not better.4.11 Land UseExisting SituationThe proposed site is on land owned by TfNSW and zoned for the purposes of City BusinessCentre under the Hurstville LEP. The land where the new monopole and cabinets are to besituated and where trenching is required is not actively used for TfNSW activities (i.e. an accessPage 48 of 75

oute or storage area). The immediate neighbouring land uses are mainly residential andcommercial.Potential ImpactsThe proposal will not affect or alter the current use of the site or the immediate surrounding areaas a rail corridor. It will not have effects on the use of the neighbouring properties.Control MeasuresNo specific control measures are required.4.12 Socio-Economic EffectsExisting SituationThe proposed site is in the Hurstville LGA which, according to the 2011 census the suburb ofHurstville has a population of around 26,040. Hurstville is a residential and commercial suburb.The railway line bisects the suburb of Hurstville in an area where there are number of differentland uses. Residential receivers, commercial facilities and Hurstville Station are in closeproximity to the proposed DBS site.Potential ImpactsSocial and economic considerations typically focus on the effect on the local community as awhole, and on local businesses. Amenity issues such as noise, visual impacts and traffic aresome of the key areas that can affect the community and are discussed in detail in sections 4.5,4.10 and 4.14.Construction is unlikely to have an adverse effect on nearby businesses, as work will be withinthe rail corridor. Noise impacts will be temporary (less than six weeks). There will be no traffic oraccess changes for businesses or residents.The site will be appropriately fenced off during construction. In operation, the facility will befenced off and pose only a minimal risk to public safety.There will be positive long term effects resulting from the proposal, as the new DTRS willprovide a more effective communication service and improve the safety of the rail network.There may be minor short-term positive impacts for the surrounding area as a result of the needfor materials, transport, food, services and accommodation.The DTRS project has a capital value of approximately $225 million and will generate over 100jobs over the life of the project.Control MeasuresIn addition to the control measures proposed in the noise, traffic and visual sections, othercontrol measures are outlined below.Page 49 of 75

Nearby residents and businesses will be informed about the nature and timing of works.Signage will notify the public about the works.Appropriate fencing around the site will help maintain public safety during construction andoperation.4.13 Electromagnetic Energy (EME)OverviewElectromagnetic energy (EME) is the energy stored in an electromagnetic field. RadiofrequencyEME refers to the EME generated by radio waves. EME is a factor of everyday life and isemitted by natural sources such as the sun and earth, and by man-made sources operating onradio waves (e.g. TV and radio broadcasts), baby monitors, model planes, mobile phone basestations and radio communications facilities.The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has established aradiation protection standard specifying limits for continuous exposure of the general public andoccupational workers to radio frequency emissions.Potential ImpactsEME levels emitted by the new DBS have been estimated at 1.5 metres above ground level atvarious distances from the proposed antennas. It should be noted that the actual EME levelswill be significantly less than predicted due to path losses and the fact that the DBSautomatically minimises transmitter power to serve only established phone calls. The maximumcumulative EME level at 1.5 metres above the ground is estimated to be 0.029% of theARPANSA exposure limits. There are likely to be negligible EME impacts during operation. TheEME report is included at Appendix 4.Control MeasuresThe various elements will be located in areas that are not accessible by the public. However,the following control measures will also minimise health and safety risks.Appropriate signage will be placed around the site to warn people of the potential hazards.All people required to work around occupationally hazardous radio frequencies willundergo RadHaz training.4.14 Traffic and AccessExisting SituationAccess to the proposed site will be via an existing TfNSW access gate on an access road thatconnects to Forest Road, directly adjacent to the site. The land is suitable for vehicle use duringthe construction period and there is no need to develop a new access track or road.Page 50 of 75

Potential ImpactsDuring construction, there will be an increased number of vehicles using the local streets,however, the anticipated increase in the volume of traffic is relatively small (about four to sixtruck movements per day).As works are to take place in the rail corridor access changes to local roads or access todriveways are not expected.Vehicular traffic in the rail corridor will be limited to concrete and delivery trucks for the DBS andpower cabinets and the monopole sections and trucks with pile boring or trenching equipment.These trucks are not large enough to prevent access via the access gate.There will be some traffic movement associated with vehicles that will need to access the sitefor maintenance requirements. However, the volume of traffic will be very small and will notadversely impact on the surrounding road network. It is proposed that the monopole andantennas be accessed via an elevated work platform or through the use of a ladder and duallard system.Control MeasuresImpacts associated with traffic and access will be minimised through a range of controlmeasures, which will include, but will not be limited to those outlined below.A Traffic Management Plan will be developed for the site.A dilapidation survey will be completed prior to construction commencing.Pavement or road surfaces damaged during construction will be restored when work isfinished.The Traffic Management Plan will ensure compliance with Australian Standard AS1742.3-2002 Manual of uniform traffic control devices – traffic control devices on roads.4.15 Utilities and ServicesExisting SituationThere is a fibre pit six metres north of the proposed site. The railway track is approximately 10metres south of the proposed site. There are railway stanchions along the railway track. Noother services have been identified in close proximity of the site.Potential ImpactsThe facility will be connected to the existing electricity supply and fibre network and does notrequire connections to water or gas.There are a number of public utilities near the site and there is the potential for some known orunknown services to be impacted during excavation. Depending on the service, outages orinterruptions could affect nearby properties or the rail network.Page 51 of 75

Control Measures• Ensure that a Dial Before You Dig call and a services search are undertaken to identifyservices.• Public utility providers will be consulted to minimise impacts during utility relocations orreadjustments.4.16 Light spillThere may be some light spill impacts during the proposed works since the night work isproposed for cable connection and antenna installation at the station. However, there is no newpermanent lighting proposed. Light sources will not be directed to residential properties andthere is dense vegetation screening surrounding the sites.4.17 Demand on ResourcesConstruction materials are readily available and will be sourced from local contractors wherepossible.4.18 Cumulative Environmental EffectsCumulative impacts often result when several different construction projects are scheduled forsimilar times and locations.A search of the Department of Planning and Infrastructure’s Major Projects register wasundertaken, which identified a Mixed-use Development project on Treacey Street approximately480 metres east of the site has been determined and approved. However, even if the twoprojects were to take place simultaneously, it is unlikely that there will be cumulativeenvironmental effects due to the distance between the two sites.The Planning and Development website for Hurstville LGA was undertaken and identifies arecently-listed construction project on Forest Road approximately 88 metres east of theproposed site. However, due to its recent listing, it is unlikely that the two projects will take placeat the same time. The Planning and Development website for Kogarah LGA was undertakenand did not identify any projects in close proximity to the site.There is also a risk of cumulative impacts if unscheduled work, e.g. emergency work by otherutilities or developers, is required. Such situations will be monitored and addressed by theProject Manager.The Hurstville West Portal DBS site is one of a large number of radio communications facilitiesbeing installed across the electrified rail network as part of the DTRS project. In terms oflocalised cumulative construction impacts, the nearest construction for the DTRS project will beat the Hurstville Outdoor Location 1 site, which is about 540 metres east of the proposed sitewithin the railway corridor. Even if both facilities were constructed simultaneously, it is not likelyPage 52 of 75

cumulative noise or local traffic impacts will result as the access gate for Outdoor Location 1 isoff Hill Street, and the access driveway for Outdoor Location 2 is off Forest Road.Overall this work, as part of the DTRS project, will result in significant benefits by providing amore effective communications systems for the rail network. The GSM-R system is in usearound the world and allows for continuous communications coverage, the capacity to makesimultaneous calls and greatly improved emergency calling capabilities. Once active, the DTRSwill provide a more effective communications system that will assist in the safe and efficientoperation of the electrified rail network.Control Measures• Any other major development or works planned in the vicinity of the site will be furtherinvestigated before construction begins.• Consultation with Hurstville City Council, Kogarah City Council and other relevantstakeholders regarding other developments will be undertaken on an ongoing basis.Page 53 of 75

Appendix 1: Principles from the TelecommunicationsFacilities GuidelinesPrinciple 1: A telecommunications facility is to be designed and sited to minimise visualimpact.Principle(a) As far as practical, a telecommunicationsfacility that is to be mounted on an existingbuilding or structure should be integrated withthe design and appearance of the building orstructure.(b) The visual impact of telecommunicationsfacilities should be minimised, visual clutter isto be reduced particularly on tops of buildings,and their physical dimensions (includingsupport mounts) should be sympathetic to thescale and height of the building to which it is tobe attached, and sympathetic to adjacentbuildings.(c) Where telecommunications facilitiesprotrude from a building or structure and arepredominantly backgrounded against the sky,the facility and their support mounts should beeither the same as the prevailing colour of thehost building or structure, or a neutral coloursuch as grey should be used.(d) Ancillary facilities associated with thetelecommunications facility should bescreened or housed, using the same colour asthe prevailing background to reduce itsvisibility, including the use of existingvegetation where available, or newlandscaping where possible and practical.ProposalThe Yagi antennas at Location 4 will bemounted to the existing west end portal of thetunnel and will be integrated into the designand appearance of the structure.The design and site selection process aimedto minimise visual impact. This has beenachieved by selecting a location inside the railcorridor where there is already a level ofdisturbance, the presence of verticalstructures as well as trees along the edge ofthe rail corridor. The selection of a monopoleand antenna mounting system that isunobtrusive with minimal visual bulk will alsominimise visual impact.The Yagi antennas that are proposed to bemounted to the west end portal of the tunnelwill be of similar colour to the tunnel.The DTRS cabinet will be located within theApparatus Room 40 metres north-west ofOutdoor Location 2 and will be out sight of thepublic. The DBS/power cabinet will be locatedwithin the portal and surrounded by a retainingwall and will also be out of site of the public.Page 66 of 75

Principle(e) A telecommunications facility should belocated and designed to respond appropriatelyto its rural landscape setting.(f) A telecommunications facility located on, oradjacent to, a State or local heritage item orwithin a heritage conservation area, should besited and designed with external colours,finishes and scale sympathetic to those of theheritage item or conservation area.(g) A telecommunications facility should belocated so as to minimise or avoid theobstruction of a significant view of a heritageitem or place, a landmark, a streetscape, vistaor a panorama, whether viewed from public orprivate land.(h) The relevant local government authoritymust be consulted where the pruning, lopping,or removal of tree or other vegetation wouldcontravene a Tree Preservation Orderapplying to the land or where a permit ordevelopment consent is required.(i) A telecommunications facility that is nolonger required is to be removed and the siterestored, to a condition that is similar to itscondition before the facility was constructed.(j) The siting and design oftelecommunications facilities should be inaccordance with relevant Industry DesignGuides.ProposalThe proposed site is not in a rural area. It is inthe rail corridor adjacent to a residential andcommercial area.The proposed DTRS site is not located withinor adjacent to a Heritage item.The proposed facility will not block orsignificantly obstruct views of heritage items orother landmarks of state significance.The proposed monopole is less than 500millimetres wide at the top and will not have aheadframe supporting the antennas. Themonopole will not represent a dominantstructure in the view lines of people occupyingthe residential properties in the surroundingarea.No native vegetation will be removed.Should the facility ever become redundant, thevarious elements will be decommissioned andremoved. Following removal, the land will berestored as close as practicable to itscondition before work began.The proposed design has been completedusing “best industry practice” and complieswith the relevant standards regardingstructural engineering, EME and constructionprocedures.Page 67 of 75

Principle 2: Telecommunications facilities should be co-located wherever practical.Principle(a) Telecommunications lines are to belocated, as far as practical, underground orwithin an existing underground conduit orduct.(b) Overhead lines, antennas and ancillarytelecommunications facilities should, wherepractical, be co-located or attached to existingstructures such as buildings, public utilitystructures, poles, towers or other radiocommunications equipment to minimise theproliferation of telecommunication facilitiesand unnecessary clutter.(c) Towers may be extended for the purposesof co-location.(d) The extension of an existing tower mustbe considered as a practical co-locationsolution prior to building new towers.(e) If a facility is proposed not to be colocatedthe proponent must demonstrate thatco-location is not practicable.(f) If the development is for a co-locationpurpose, then new telecommunications facilitymust be designed, installed and operated sothat the resultant cumulative levels of radiofrequency emissions of the co-locatedtelecommunications facilities are within themaximum human exposure levels set out inthe Radiation Protection Standard.ProposalThe fibre connections for the DTRS network willbe in existing conduits or in new undergroundconduits wherever feasible or possible.Co-location on other communications towershas been considered. No other towers weredeemed appropriate or in a location to providesufficient network coverage, as such a newmonopole is proposed (refer Section 3.5).The proposal does not involve the use of anexisting tower. The extension of existing towersin the area was considered and deemedunsuitable.The proposal does not involve the use of anexisting tower.There are no suitable communications towersin the target coverage area that would satisfythe coverage objectives as well as the networkrequirements of the DTRS project.Co-location is not proposed.Page 68 of 75

Principle 3: Health standards for exposure to radio emissions will be met.Principle(a) A telecommunications facility must bedesigned, installed and operated so that themaximum human exposure levels toradiofrequency emissions comply withRadiation Protection Standard.(b) An EME Environmental Report shall beproduced by the proponent of developmentto which the Mobile Phone Network Codeapplies in terms of design, siting of facilitiesand notifications.The Report is to be in the format required bythe Australian Radiation Protection NuclearSafety Agency (ARPANSA). It is to show thepredicted levels of electromagnetic energysurrounding the development comply withthe safety limits imposed by the AustralianCommunications and Media Authority andthe Electromagnetic Radiation Standard, anddemonstrate compliance with the MobilePhone Networks Code.ProposalThe proposed facility will comply with theARPANSA standard in relation to humanexposure to EME. An EME report has beencompleted and is found at Appendix 4.This report demonstrates compliance with theARPANSA standard for the operation of a radiocommunications facility in Australia.The proposal is not for a mobile phone networkand is not subject to the Code for theDevelopment of Mobile Phone NetworkInfrastructure commonly known as the ACIFCode.An EME report has been completed and isfound at Appendix 4.Principle 4: Minimise disturbance and risk, and maximise compliancePrinciple(a) The siting and height oftelecommunications facility must comply withrelevant site and height requirements specifiedby the Civil Aviation Regulations 1988 and theAirports (Protection of Airspace) Regulations1996 of the Commonwealth. It must notpenetrate obstacle limitation surface shown onrelevant Obstacle Limitation Surface Plan thathas been prepared by the operator of anProposalThe provisions of the Civil AviationRegulations 1988 and the Airports (Protectionof Airspace) Regulations 1996 wereconsidered during the design and sitingprocess. There is no need for the installationof a warning light or aircraft navigation light, asthe proposal does not penetrate the ObstacleLimitation Surface.Page 69 of 75

PrincipleProposalaerodrome or airport operating within 30kilometres of the proposed development andreported to the Civil Aviation Safety AuthorityAustralia.(b) The telecommunications facility is not tocause adverse radio frequency interferencewith airport, port or Commonwealth Defencenavigational or communications equipment,including the Morundah CommunicationFacility, Riverina.(c) The telecommunications facility andancillary facilities are to be carried out inaccordance with the applicable specificationsof the manufacturers for the installation ofsuch equipment.(d) The telecommunications facility is not toaffect the structural integrity of building onwhich it is erected.(e) The telecommunications facility is to beerected wholly within the boundaries of aproperty where the landowner has agreed tothe facility being located on the land.(f) The carrying out of construction of thetelecommunications facilities must be inaccordance with all relevant regulations of theBlue Book – ‘Managing Urban Storm water:Soils and Construction’ (DECC 2008), or itsreplacement.(g) Obstruction or risks to pedestrians orvehicles caused by the location of the facility,construction activity or materials used inconstruction are to be mitigated.TfNSW will operate the radio facility with itsown spectrum and the facility will not causeinterference with other networks. All radiotransmitters will use the frequency assigned toTfNSW for the exclusive use of TfNSW.The installation and operation of the radioequipment and antennas will be carried out inaccordance with the manufacturers’specifications.The proposed facility will not be connected toan existing building.The proposed facility will be inside the railcorridor that is owned by TfNSW. TfNSW isthe proponent of the network and agrees tothe use of the land for the proposed radioequipment.The activities associated with construction andinstallation will be done in accordance withsediment controls, erosion controls,stormwater controls and other controlsoutlined in the Blue Book (refer Section 4.1).Construction activities will take place in the railcorridor and changes to traffic and access arenot expected.Traffic changes will be implemented inaccordance with an approved TrafficManagement Plan.Page 70 of 75

PrincipleProposalThere will be no risks to traffic or pedestriansduring the operation of the proposal.(h) Where practical, work is to be carried outduring times that cause minimum disruption toadjoining properties and public access. Hoursof work are to be restricted to between 7:00amto 6:00pm, Mondays to Fridays, 8:00am to1:00pm Saturdays, with no work on Sundaysand public holidays.(i) Traffic control measures are to be takenduring construction in accordance withAustralian Standard AS1742.3-2002 Manual ofuniform traffic control devices – Traffic controldevices on roads.(j) Open trenching should be guarded inaccordance with Australian Standard Section93.080 – Road Engineering AS1165 – 1982 –Traffic hazard warning lamps.(k) Disturbance to flora and fauna should beminimised and the land is to be restored to acondition that is similar to its condition beforethe work was carried out.(l) The likelihood of impacting on threatenedspecies and communities should be identifiedin consultation with relevant state or localgovernment authorities and disturbance toidentified species and communities avoidedwherever possible.(m) The likelihood of harming an AboriginalPlace and / or Aboriginal object should beidentified. Approvals from the Office ofEnvironment & Heritage (OEH) must beobtained where impact is likely, or AboriginalAll work associated with the development andinstallation of the DBS site will generally occurbetween 7:00am to 6:00pm, Mondays toFridays, 8:00am to 1:00pm Saturdays. Nightwork from 8:00pm to 4:00am is required forcable connection and antenna installationwork at Hurstville Station.A Traffic Management Plan will be developedand implemented during construction andinstallation activities. The procedures andmitigation measures in the plan will ensurecompliance with Australian StandardAS1742.3-2002 Manual of uniform trafficcontrol devices – Traffic control devices onroads (Refer Section 4.14).There will be no open trenches outside the railcorridor and all trenches will be covered orfilled so that they are not open overnight.No native vegetation will be removed. Theland will be reinstated to its original conditionprior to construction.The proposed activities do not require theremoval of native vegetation. A search ofthreatened species has been completed (referAppendix 3) and there is not expected to besignificant impact on threatened species.A search of the AHIMS has been completedand there are no known items or places ofarchaeological significance on the site or inthe immediate surrounding area.Page 71 of 75

Principleobjects are found.(n) Street furniture, paving or other existingfacilities removed or damaged duringconstruction should be reinstated (at thetelecommunications carrier’s expense) to atleast the same condition as that which existedprior to the telecommunications facility beinginstalled.ProposalIf suspicious items or objects are found duringexcavation, work will cease immediately andthe OEH will be consulted and works will notre-commence until OEH have granted theirconsent.Any street furniture, paving or other existingfacilities affected by the construction works willbe reinstated at the end of construction to atleast the same condition they were in beforework began.Page 72 of 75
