2.3 Requirements of the Request for Additional Information

FollowingreferraloftheproposaltotheEPAunderSection38oftheEnvironmentalProtectionAct1986,theEPAissuedanotice(EPA,2018)requestingPTAprovideadditionalinformationforreferralassessment.Thisincludedthepreparationofa:

Noise and vibration management plan (NVMP) to detail proposed noise and vibrationmanagementmeasures.

Constructionenvironmentalmanagementplan(CEMP)todetailproposedmanagementandmitigationactionsforeachofthePreliminaryKeyEnvironmentalFactors.

The CEMP is a separate document and includes the management and mitigation of noise andvibrationsgeneratedbytheproposalconstructionworks.

ThisNVMPissubmittedinaccordancewiththefollowingcriteria:

Railway operation (noise) - State Planning Policy 5.4 Road and Rail Transport Noise andFreightConsiderationsinLandUsePlanning(thepolicy).

Railwayoperation(vibration)-MinisterialStatement629,whichrelatedtotherailwaysouthofButlerStation(MinisterialStatement629).

Railway station operation - The Environmental Protection (Noise) Regulations 1997 (theregulations).

2.4 Rationale and Approach in Meeting the Environmental Objective

2.4.1 Noise and Vibration Modelling and Assessment

The resultsof thenoisemodellingandassessment informthemanagementapproach formeetingthe NVMP requirements stated in Section 2.3. The identified management actions, managementtargets and proposed review and revision of management actions are aligned with the overallproposedmanagementapproach.

Anoiseandvibrationassessmentwasundertaken, inaccordancewith thepolicy,byLloydGeorgeAcoustics(January2018),toassessthelikelytransportationnoiseandvibrationlevels,resultingfromtheproposal,onsensitivereceptors.

Whilethepolicystatesthat“transportinfrastructureprovidersshoulddesignmitigationmeasurestoachievethenoiselimit”(60dBLAeq(Day)atgroundfloorlevel,basedonthepredictedfuture(15to20years) scenarios, the noise assessment designed mitigation to achieve the policy target of 55 dBLAeq(Day)wherever practicable using noise barriers up to a height of 4metres, unless the sensitivereceptorincorporatesspecificnoisemitigationwithintheconstructionofthebuildingfacade.

NoisemodellingfortheoperationoftheproposalwasundertakenusingthecomputerprogrammeSoundPLAN8.0andincorporatingtheNordicRailPredictionMethod(KildeRep.130)algorithm.ThealgorithmhadbeenmodifiedtoreflectlocalconditionsandtrainsusingtheMETRONETrailnetwork.The3-dimensionalcomputermodelling includedexistingtopography integratedwiththeproposed



designoftherailway,whichhasbeendesignedtobeinacutting,between4-7mbelowgroundlevel,forthemajorityofthealignment. Variables includedexpectedtrain lengthsandspeeds,expectednumberoftrainmovements,existingnoisesensitivepremises,futureresidentialdevelopmentsandexistingnoisebarriers.

Thetrainconfigurationusedinthemodellingassumedalltrainswere6-carsets,havingalengthof150metres. Itwas assumed that 75 trainmovements occurred in each direction during the dayperiod(6:00a.m.to10:00p.m.)and22trainmovementsoccurredineachdirectionduringthenightperiod(10:00p.m.to6:00a.m.)

Thetrainspeedsused inthemodellingwasbasedonsimulationplotsundertakenbyAustralisRailConsulting.Thespeedsrangedfrom55km/hcomingintostationsto130km/honstraightsections.

Forthepurposesofmodelling,allbuildingswereassumedtobesinglestoreyandhaveaheightof4.0 metres. Considering the type of buildings constructed in the area and the fact that theassessmentisundertakenatgroundfloorlevel,thisapproachwasconsideredtobereasonable.

Existing noise walls were considered in the model; however, noise mitigation that has beenincorporated intoasubdivisiondesignaspartoftheDevelopmentApplicationprocess,whichmayincludenoisebarriers,specifiedfacadeprotectiononcertainlots,oracombinationofbothwerenotincludedinthisassessment.

Calibrationofthenoisemodelwasundertakenassumingapassingnoiselevelfromatraintravellingat130km/hof87dBLAmax.ThismeasurementdatawasobtainedduringthecommissioningofnewtrainsoperatingontheJoondalupline.

Thekeyassumptionsanduncertaintiesassociatedwiththenoisemodellinginclude:

Numberoftrainmovementiscorrect.

Trainspeedsareasmodelled.

Daytimenoiselevelswillbemorethan5dBabovethenighttimelevels.

Groundlevelsatexistingandproposedsensitivereceiversareassurveyedordesigned.

Noise control measures assigned to existing residential development along the alignmentareconstructedasspecified.

Noisewallsforfutureresidentialdevelopmentsareconstructedasspecified.

The assessment of noise from the railway stations will be undertaken during the detailed designstageofthestations.

ThevibrationassessmentwasbasedonmeasuredvibrationlevelsadjacenttotheNorthernSuburbsRailwayundertakenbyHerringStorerAcoustics.Theassessmentconsideredtheprofileofthetrack(straight,bend,etc)anddistancefromthetracktothesensitivereceptor.

Theattenuationofvibrationlevelsoccurswithdistancefromthesourceandthedampingpropertiesofthegroundmaterial. Basedonthemeasuredvibrationlevels,thedistancesrequiredtoachieve



the criterion of Curve 1.4 in Australian Standard 2670.2-1990 “Evaluation of human exposure towhole-bodyvibration;Part2:Continuousandshock-inducedvibrationinbuildings(1to80Hz)are:

NearStation-50metres

Insidebend-55metres

Outsidebend-40metres

StraightTrack-40metres

Thesedistancesassumethetrainwillbetravellingathighspeeds.

Thekeyassumptionsanduncertaintiesassociatedwiththevibrationpredictionsinclude:

Vibrationmeasurementresults fromtheexistingrailwaytranslate to theproposedrailwaydesignandgroundconditions.

2.4.2 Noise and Vibration Modelling and Assessment Results

TheresultsofthenoisemodellingshowedthatthePolicynoisetargetwasexceededatanumberofreceiverlocationsandassuch,noisemitigationisrequiredtobeincorporatedintothedesignoftherailwaytoachievethiscriterion,wherepracticable.

ForthePTA,theonlypracticablenoisemitigationmeasureavailableistoinstallnoisebarriersalongtherailreserveboundary,wherepracticable,atallidentifiednoisesensitivepremises.Forreasonsofpracticability,noisewallshavebeenlimitedtoaheightof4metresabovegroundlevel.

The recommendednoisewalls are presented inFigures 2-2 to 2-7. While these noisewalls havebeen designed to achieve the Policy noise target, wherever practicable, they do not take intoconsideration other mitigation measures, such as house facade protection, which are permittedunder the Policy. For example, where urban development includes the requirement for facadeprotectiononcertain lots,higherexternalnoise levelsarepermittedand thereforea reduction intheheightofthenoisewall,ortheeliminationofthewall,wouldbeconsideredacceptable.

2.4.3 Management Approach

Themanagementapproachfornoisehasbeeninformedbythepolicyandindustrybestpractice.

ForvibrationtheapproachisidenticaltoMinisterialStatement629(relatingtotherailwaysouthofButler Station), which references Australian Standard AS2670.2-1990: Evaluation of humanexposuretowholebodyvibration-Part2:Continuousandshockinducedvibrationinbuildings(1to80Hz). ThisStandardcharacterisessources (ofvibration)whichoperate intermittently,butwhichwouldproducecontinuousvibrationifoperatedcontinuously,suchasrailwaytrains.

2.4.4 Rationale for Choice of Management Targets

The rationale for the choice of management targets to achieve the environmental objectives foramenityisdetailedbelow:

Themanagement target foroutdoornoisehasbeendevelopedby theWesternAustralianPlanning Commission in the policy based on emissions of road or rail transport noise asreceivedatanoise-sensitivelanduse,namely:

o for new road or rail infrastructure proposals, at 1 m from the most exposed,habitablefaçadeofthebuildingreceivingthenoise,atgroundfloorlevelonly;and

o for new noise-sensitive development proposals, at 1 m from the most exposed,habitable façade of the proposed building, at each floor level, andwithin at leastoneoutdoorlivingareaoneachresidentiallot.

In the application of these outdoor noise criteria to new major transport projects, theobjectivesofthePolicy isthatthenewinfrastructurebedesignedandconstructedsothatnoiseemissionsareatalevelthat-

o Provides an acceptable level of acoustic amenity for existing noise-sensitive landusesandfortheplanningofnoise-sensitivedevelopments;

o Isconsistentwithotherplanningpoliciesandcommunityexpectations;and

o Ispracticablyachievable.

Themanagement targets forground-bornevibration resulting fromthe trainpass-byswasgiven in theMinisterialStatement629for theexistingrailwaysouthofButlerStation.TheMinisterial Conditions required that the proponent meet specific vibration criteria withreference to the Australian Standard AS 2670.2-1990: Evaluation of human exposure towholebodyvibration-Part2:Continuousandshockinducedvibrationinbuildings(1to80Hz). This Standard characterises sources (of vibration) which operate intermittently, butwhichwouldproducecontinuousvibrationifoperatedcontinuously,suchasrailwaytrains.The preferredmethod of assessing the influence of continuous vibrations is to assess therootmeansquare(RMS)valueoftheweightedparticleacceleration.Intermsofvibrationalenergy,bothparticleaccelerationandvelocityareidentical.

Themanagementtarget fornoiseresultingfromoperationoftherailwaystations isbasedon the requirements and assigned levels contained within the Environmental Protection(Noise)Regulations1997.
