1 Introduction and Overview1.1 Purpose of This ReportThis Submissions Report documents and considers submissions received regarding theproposed Warrawee Substation. The report also provides an overview of the Review ofEnvironmental Factors (REF) process and document, the REF exhibition process and arevised statement of commitments which reflects the main issues identified by thesubmissions from the community and Ku-Ring-Gai Council.1.2 Project OverviewRailCorp is carrying out a program of infrastructure works across the Sydney rail network toincrease the capacity and reliability of the electrical system that powers trains, namely theTraction Supply Upgrade (TSU) Program. The upgrade will also meet the electrical demandsof the new generation air-conditioned fleet, the Waratah trains, to enable increased patronageof public transport.As part of the TSU program, a new Substation is proposed within the rail corridor atBrentwood Avenue, Warrawee.The proposal is of a type that meets the definition of an electricity transmission or distributionnetwork under Clause 40 of the ISEPP. Under Clause 41(1) of the ISEPP, development forthe purpose of an electricity transmission or distribution network may be carried out by or onbehalf of an electricity supply authority or public authority without consent on any land.As the proposal forms part of an electricity transmission or distribution network and it is to beundertaken by or on behalf of a public authority (RailCorp), the proposal is permissible withoutconsent under Clause 41 of the ISEPP.As the determining authority, RailCorp is responsible for assessing the findings of the Reviewof Environmental Factors (REF), and the submissions report to determine whetherrequirements for assessment under Part 5 of the EP&A Act have been met.Page 5

1.3 Scope of the proposalKey features of the proposal are summarised in Table 1.1.Table 1.1Building sizeKey features of the proposalBuilding footprint of approximately 284 m 2 . The total area in which thesubstation (including building, hardstand areas, and driveways) wouldbe located on is approximately 1170 m 2 .Facilities to beprovided insidethe buildingThe following facilities would be included in the substation building:• Two incoming 33kV feeders• Two physically separate 33kV switchboards and associatedswitchgear• Two 33kV/600V rectifier transformers• Two 600V/1500V DC rectifiers• Two 600V/415V auxiliary transformers• One 0.5mH 4000A reactor• DC circuit breaker cubicles for the following:- Two 1500V DC rectifier DC circuit breakers- Four 1500V DC feeder DC circuit breakers- One DC 1500V DC for an harmonic filter- One test bay, with spare DC circuit breakers• Four three position isolating and rail connect switches in the1500V DC isolating switch area• One common equipment panel• One rail earth contactor panel• One main negative bar for traction return, one control negativebar, voltmeter test rail in 1500V DC switch area and one earth bar• Auxiliary power supply and reticulation via distribution board• Battery room• Communications services including VoIP phones• Site electrical services include site lighting• Earthing of high voltage and low voltage systems and bonding ofstructure components.Page 6

Building formThe design provides for a skillion roof to Brentwood Avenue to visuallybalance the narrow building and the relatively tall walls. Walls are facebrick and would include carefully located penetrations for doors andventilation louvres. It is proposed that external face bricks would beselected for resistance to graffiti, and that mortar joints would bestruck flush to facilitate cleaning.A retaining wall is required at the southern end to allow even gradelevelling of the site.Facilitiesadjoining thebuilding• Transformer yard• Link yard• Concrete hardstand surrounding the building, providing parkingand loading/unloading areas for service vehicles• Transformer and reactor compounds are proposed as concreteblockworkUtilityconnections• An undertrack crossing to allow conduits to be installed• Connection to Council’s stormwater system• Connection to sewer• Relocation of existing RailCorp services within the rail corridorStormwatercontrols anddrainageThe transformer and reactor would be located within a bunded area tobe constructed in accordance with relevant Australia Standards andMaterial Safety Data Sheets. This would ensure that any spills arecontained. The bunded area would contain an oil/water separator toallow the oil to be selectively removed and disposed of.An oil/water separator would be installed on the inlet to the pit thatwould capture runoff from the bunded areas. Water would bedischarged to the stormwater network and oil from the pit would bepumped out for offsite disposal.A new drainage system is proposed to divert the existing open drainpast the new substation building.LightingSecurityAccessExternal security lighting would be installed in a manner whichminimises light spill to areas beyond the site boundary.Security fencing around the substation and the bunded yards wouldbe compliant to RailCorp standards for substation fencing. Fencingaround the substation would be 2.7 metres tall and would beconstructed of weld mesh panels. The fencing would be toppedcroctop only. All steel fence members are galvanised and thenfinished in black powdercoat.Two accesses to the site from Brentwood Avenue would be provided.These would be two concrete driveways. The southern access wouldprovide access to Bunded Yard No. 1 and the substation building. Thenorthern access would provide access to Bunded Yard No. 2 and thesubstation building.Page 7

Fuel/chemicalstorage on site• Approximately 3,100 litres of oil would be stored within thereactor.• Approximately 11,000 litres of oil would be contained within thetransformers.1.4 Studies undertakenTo assess any impacts of the project, the following specific environmental studies have beenundertaken:• Noise and vibration• Flora and fauna1.5 Need and Benefits of the ProjectThe substation is part of the TSU program of electrical upgrading works associated with therollout of the new fleet of Waratah trains to the CityRail network. Once fully operational, thesubstation will provide more power to run trains in this region and reduce the risk of disruptionto rail services by improving service reliability.Based on the power requirements of the new and existing rolling stock, RailCorp modelled thepower demand across the network to identify infrastructure that would require upgrading. Theassessment of the electrical network on the North Shore Line found the existing sectionbetween Gordon and Hornsby would not meet the expected power requirements without anadditional substation between Turramurra and Warrawee.RailCorp then modelled various proposals until the optimum engineering solution wasachieved. The modelling indicated that a new substation would be required to replace theexisting Turramurra Sectioning Hut, utilising its connection to the overhead wiring.The substation is limited to be located within 200 metres of this location to minimise thepotential for arcing (Sparking) between the different sections of the overhead wiring resultingfrom voltage variances that occur in long lengths of cable that could cause the overheadwiring to burn down.1.5.1 Project ImpactsThe key impacts that could potentially result from the implementation of the project wouldinclude:• Noise and Vibration• Traffic and Access• Hydrology and Flooding• Flora and Fauna• Visual Impact and Lighting• Heritage• Socio Economic• Air Quality• Soil and Groundwater Contamination• Land Use• Security• Greenhouse GasPage 8

These impacts are discussed in detail in Chapter 3 of the REF. A complete summary of thekey identified impacts and proposed management commitments are provided in theStatement of Commitments Chapter of this document (Chapter 4). It has been determinedthat provided these commitments are implemented, the identified impacts can be mitigatedsuch that the environmental impacts associated with this project are not significant.1.6 Conclusions of the Review of Environmental FactorsProcessThrough the REF process, and consultation with the local community and Ku-Ring-GaiCouncil, it has been possible to identify the environmental, social and economic impacts thatthe construction and operation of the Warrawee Substation would have in the local area andacross the wider Sydney region.Whilst some impacts would occur with the development of this project, these impacts can bemitigated such that they do not have a significant detrimental environmental effect. Thebroader positive impacts to transport in the North Shore Sydney region and to the widerSydney rail network justify the identified localised impacts.The REF document details the proposed control measures that are to be implemented duringthe construction and operation of the facility, and through the public exhibition process andconsultation with Ku-Ring-Gai Council these measures have been expanded to addressconcerns raised. These expanded measures are listed in Chapter 4 of this SubmissionsReport and will also be required to be implemented along with any Conditions of Approval thatwould be attached to the project determination.Provided the mitigation measures identified in the Conditions of Approval are implementedduring the construction and operational phases of the development, these impacts areconsidered acceptable and the total net impact of the development of this project will bepositive.1.7 Approval Pathway1.7.1 Statutory RequirementsIn New South Wales, proposals such as the Warrawee Substation are subject to theEnvironmental Planning and Assessment Act (EP&A Act), 1979 and relevant instruments thatare created under it. The Act sets out the processes for obtaining planning approval andrelated matters.As the proposal is covered by the State Environmental Planning Policy (Infrastructure), 2007(Infrastructure SEPP) which broadly aims to facilitate the effective delivery of infrastructureacross New South Wales, this project is to proceed for assessment under the Part 5 pathway.The proposal includes mitigation measures which have been incorporated into the designensuring that there will not be significant environmental impacts. The Infrastructure SEPPprovides that development for certain rail infrastructure facilities can be carried out withoutplanning approval thus overriding the Council zoning and Local Environmental Plans (LEPs).1.7.2 Determination ProcessUnder Part 5 of the EP&A Act, RailCorp is the proponent and the determining authority of theProject. The assessment and approval process for the Project is illustrated in Figure 1.2below. As the determination authority, RailCorp will assess the findings of the environmentalPage 9

assessment process, the REF document and the Submissions Report to determine whetherrequirements for assessment under Part 5 of the EP&A Act have been met.RailCorp will also consider all community and Council comments received during thesubmissions period to determine whether these comments have been appropriatelyaddressed in the Submissions Report. Following this review process, RailCorp will make adetermination as to whether to proceed with the project, in line with the provisions of Part 5 ofthe EP&A Act.Should the project proceed, approval conditions would be attached to the determination toensure potential impacts identified in the REF and submissions processes are adequatelyaddressed and mitigated.Figure 1.2 – Determination PathwayRailCorp develop a pre-concept design and RailCorp determine approvalprocess for the project being a part 5 assessment.GHD on behalf of RailCorp undertakes environmental assessment of the project,consults with Council and prepares the REF under Part 5 of the EP&A Act.REF placed on public exhibition and written submissions invited from thecommunity.Submissions responded to and summarised in the submission report forRailCorp.WE ARE HERERailCorp assesses the REF and submissions report and determines the project.2 Exhibition ProcessThe REF for the Warrawee Substation was placed on public exhibition on the RailCorpwebsite with notification of the local Council and residents within a 250 metre proximity havebeen consulted on the proposed works as part of RailCorp’s responsibility as a DeterminingAuthority. Residents and the Council have had the opportunity to comment on the REF for theproposed project.Extension of the community notification zone was made to include Cherry Street, St JamesLane and Laurel Avenue. Knox Grammar and St James Church were contacted and offered abriefing.On 18 May, at the request of residents, approximately 20 owners including nine householdshad the opportunity to meet with RailCorp representatives to discuss community concernsand issues regarding the proposed Substation.Initial outcomes of this community consultation were as follows;Page 10

3.3 Response to submissions3.3.1 Why is the substation being constructed in the area chosen? Hasthere been research into an alternative location?Issue Addressed: Location of SubstationAddressing Submissions: 2, 3, 5, 8, 11, 12, 14, 15, 19, 21, 22, 23, 26, 27, 28, 30, 32, 33, 34, 37, 38,and 39.RailCorp is undertaking a program of works across Sydney to increase the capacity andreliability of the electrical network. The TSU program is delivering vital enabling works tomeet the power requirements of the new Waratah fleet, and to support the transition to 100%air-conditioned fleet with all trains becoming 8-car sets.Based on the power requirements of the new and existing rolling stock, RailCorp modelled thepower demand by undertaking a number of power studies across the network to identifyinfrastructure that would require upgrading. The assessment of the electrical network on theNorth Shore Line found the existing section between Gordon and Hornsby would not meet theexpected power requirements without an additional substation between Turramurra andWarrawee.Section 6.4 of the TSU Power Study 5 Scope of Works (Version 1.03) dated 17 January 2008States:A new 2*5MW substation is to be built at Warrawee. Existing early designdocumentation indicates tat that the substation shall be built at NS21+460 and theTurramurra Section Hut shall be decommissioned. The proposed Warraweesubstation shall feed the same overlaps as the existing Turramurra Section Hut.Substations are required to be located within 200 metres of the overhead wiring connectionpoint to minimise the potential for arcing (sparking) between the different sections of theoverhead wiring (resulting from voltage variances that occur in long lengths of cable) thatcould cause the overhead wiring to burn down.If there is not a suitable location within 200 metres either side of the overhead wiringconnection point RailCorp would have to undertake an extensive analysis to identify a feasibledistance to locate the substation from the overhead wiring connection point. The analysisconsiders the effects of the rolling stock power requirements, topography of the rail line, timetabling including train frequency and stopping patterns, tack layout and surroundinginfrastructure that interfaces with the earthing system of the substation.Turramurra Sectioning Hut is located on the eastern side of the rail corridor between CherryStreet and Brentwood Avenue at Warrawee. It connects to the overhead wiring at 21.28km to21.34km from Sydney Terminal.RailCorp assessed the rail corridor within a 400 metre building envelope (200 metres eitherside of the required overhead wiring connection point) for suitable locations to place theproposed substation. The assessment confirmed that there were no suitable locations on theWestern side of the corridor due to construction and access difficulties associated with thesteep embankments and in close proximity (less than 5 metres) to adjacent residences. Therail corridor on the Eastern side of the corridor, near the existing section hut was found to betoo narrow and in close proximity (less than 5 metres) to adjacent residences in CherryStreet.The only site within 400 metre building envelope that can accommodate the proposedbuilding is the parcel of land on the Eastern side of the corridor at the end of BrentwoodAvenue. This site has the advantage of being furthest away (approx. 20 metres) fromadjacent residences. The site also provides access for ongoing maintenance.Page 15

Given the analysis to identify distances beyond the 400 metre building envelope takes inexcess of six months to complete, utilises scarce critical resources and there is a suitablelocation within the 200 metres of the overhead wiring connection point, RailCorp considersthe Brentwood Avenue site as the only suitable site from an engineering and the optimum sitefrom a community impact perspective.3.3.2 How will RailCorp ensure our properties will not be impacted uponby construction activities or the operation of the substation?Issue Addressed: Construction Noise and Vibration, CompensationAddressing Submissions: 1, 3, 5, 7, 12, 17, 19, 24, 26, 29, 30, 34 and 39.A property dilapidation report will be provided to the immediately adjacent residents, prior toconstruction commencing and at the completion of construction works. It is not expected thatthe construction works will cause any structural damage to properties in the immediatevicinity, however if final dilapidation report indicates damage due to project works, these willbe repaired.If residents feel that damage has been caused to their property (during the constructionperiod) as a result of construction activities, RailCorp will carry out an inspection comparingresults to the initial dilapidation report and any damage due to project works will be repairedby RailCorp.3.3.3 The areas around Brentwood Ave and Hastings St are frequentlyused by many school children and their families not only foraccess to local schools but for travelling by rail to other schoolsalong the line. How will RailCorp ensure their safety?Issue Addressed: Pedestrian Management and SafetyAddressing Submissions: 1, 3, 6, 7, 8, 14, 17, 18, 19, 22, 24, 26, 28, 29, 30, 33, 34, 36, and 39.RailCorp has outlined the control measures in section 3.12 of the REF ‘Traffic & Access.’The following control measures would be implemented to minimise impacts on the traffic andtransport network:• A traffic management plan would be developed in consultation with Council to detailtraffic control measures along Brentwood Avenue and Hastings Road. This would beincorporated into the construction environmental management plan;• Access along the pedestrian path adjacent to the corridor to be maintained at alltimes during construction;• A designated heavy vehicle route would be identified within the traffic managementplan. Heavy vehicles accessing the site would be required to use this route;• Vehicle movements to and from the site to be minimised during school start and endtimes;• Liaison with Ku-Ring-Gai Council is required to confirm the design, location andapproval requirements for the proposed site accesses;• Signage and traffic control devices would be installed to alert motorists andpedestrians to changes to local traffic conditions during the construction period; and• Oversized vehicle movements would be discussed with RMS and NSW Police prior tothem occurring.RailCorp will discuss with Council the option of extending the footpath in Brentwood Avenue.No members of the project team will be permitted to park within Brentwood Avenue, and notrucks will park in the street (with the exemption of special loads). In this regard, there will bezero tolerance to workers vehicle problems in Brentwood Avenue.Page 16

In addition, traffic control officers will be engaged to ensure safe pedestrian and vehicularmovements during the construction period. The Traffic and Pedestrian Management plans willbe available upon request.3.3.4 Street parking is limited and the street is very narrow. How willconstruction parking be managed?Issue Addressed: Traffic ManagementAddressing Submissions: 1, 3, 6, 7, 8, 10, 11, 12, 14, 16, 17, 18, 19, 24, 25, 26, 27, 28, 29,30, 33, 34, 36, 37, and 39.RailCorp has outlined the control measures in section 3.12 of the REF ‘Traffic & Access.’At the peak of the construction period, it is anticipated that approximately 20 staff would beworking on the site. Under a worst-case scenario, it is assumed that all of these staff woulddrive to the site in separate cars. This short term increase in vehicular movements is unlikelyto have a significant effect on the function of the local road network. There would be on-siteparking, however during the worst case scenario, construction staff may be required to park inthe surrounding streets.Project staff and workers will be encouraged to travel by rail to the site where possible.In addition, a traffic management plan will be developed in consultation with Counciladdressing parking issues. It is envisaged that most construction parking will occur on-siteand public transport is to be used when possible.3.3.5 The project has obviously been in planning for some time now,why has the community only been consulted now with only a 21day exhibition period to submit submissions?Issue Addressed: Consultation Process, and Project Approval ProcessAddressing Submissions: 3, 5, 7, 8, 11, 12, 13, 14, 15, 16, 22, 23, 24, 27, 33, 34, 36, 37, 38The consultation process commenced when the proposed design was progressed sufficientlyenough to enable the REF to be finalised and placed on exhibition.RailCorp representative’s door knocked a 250m radius around the site of the proposedWarrawee substation on 3 May 2012 and provided the REF on the RailCorp internet site.Residents, groups and Government authorities were given a 21 day notification period asrequired under the SEPP Infrastructure (until 23 May 2012) to make their comments on theREF. RailCorp’s Traction Supply Upgrade (TSU) Program Manager and Community RelationsManager met on site with residents on 18 May 2012 to discuss the proposed project andresidents concerns. At the request of residents, this exhibition period was extended until11.59pm, 7 June 2012. RailCorp also extended the consultation area from 250 metres toapproximately 500 metres around the proposed site.For the purposes of Part 5 of the Environmental Planning and Assessment Act 1979 (EP & AAct) and the State Environmental Planning Policy (SEPP) (Infrastructure) 2007, a publicauthority (such as a government department, council or state owned corporation), likeRailCorp, can be both the proponent of a project and the determining authority that isresponsible for approving that project, and does not require Council approval.The objective of the SEPP (Infrastructure) legislation, under the Department of Planning is toassist the NSW Government, local councils and the communities they support by simplifyingthe process for providing infrastructure in areas such as education, hospitals, roads, railways,emergency services, water supply and electricity delivery.Page 17

All written submissions received during the extended public exhibition period, including latesubmissions, regarding the proposed Substation will receive an individual response to theirsubmission.
