EXECUTIVE SUMMARY

OVERVIEW

Environmental Resources Management Australia Pty Ltd (ERM) was engaged by Transport for NSW (TfNSW) to complete a noise and vibration impact assessment for construction and operational aspects of the Wentworthville Station Easy Access Upgrade (the Proposal). The Proposal is part of the Transport Access Program (TAP), an initiative by TfNSW to provide a better experience for public transport customers by delivering accessible, modern, secure and integrated transport infrastructure where it is needed most.

ASSESSMENT METHODOLOGY

The assessment was completed to achieve a scope of works that allowed for the successful identification of potential receptors situated in the vicinity of site emission sources and identification of significant noise and vibration generating plant, equipment and/or activities associated with the project and their likely/known emissions.

ERM qualitatively assessed potential impacts associated with construction road traffic noise and vibration, and operational noise and vibration. No impacts are anticipated. A quantitative construction noise and vibration impact assessment was then completed by predicting noise levels via modelling and by estimating vibration levels based on ERM test data. The predictions were completed for applicable assessment scenarios, developed based on construction data provided by TfNSW.

ERM quantified existing ambient and background noise levels in the area via measurement and developed construction noise and vibration criteria in accordance with recognised NSW standards and guidelines as applicable to the project activities.

Noise management goals were established for works within standard hours of construction and for works that may be required outside the standard recommended hours. The applicable noise management goals are summarised in Table E.1.

1. An internal noise goal of 45 dB(A) has been established by applying a correction factor of 20 dB(A) to convert from internal to external noise criteria and allow simplified comparison to noise levels predicted via modelling at external assessment locations

2. Commercial 70 dB(A) Noise Affected Management Level applies at the ground floor.


IV

RESULTS AND FINDINGS

Resultant noise and vibration levels were compared to project-specific criteria or management levels at each receptor location. Exceedances of the applicable noise affected and highly noise affected management levels have been identified. The results are discussed below:

• the daytime Noise Affected Management Level (50 dB) applicable at residential (dwelling) receptors for works within the recommended standard hours of construction will be exceeded by up to 41 dB(A) at the most affected receptor, which is 51 dB(A) above the daytime background L90 noise level. On average, noise levels will exceed this criteria by up to 16 dB for all assessed construction scenarios

• for 21 of the 56 assessed scenarios and construction areas the Highly Noise Affected Management Level (75 dB) applicable at residential (dwelling) receptors during the daytime will be exceeded by up to 16 dB(A) at the most affected receptor

• the daytime Noise Affected Management Level (45 dB) applicable at residential (dwelling) receptors for works outside the recommended standard hours of construction will be exceeded by up to 46 dB(A) at the most affected receptor, which is 51 dB(A) above the daytime background L90 noise level. On average, noise levels will exceed this criteria by up to 21 dB for all assessed construction scenarios

• the evening Noise Affected Management Level (43 dB) applicable at residential (dwelling) receptors for works outside the recommended standard hours of construction will be exceeded by up to 48 dB, which is 53 dB(A) above the evening background L90 noise level

• the night time Noise Affected Management Level (38 dB) applicable at residential (dwelling) receptors for works outside the recommended standard hours of construction will be exceeded by up to 53 dB, which is approximately 58 dB(A) above the night time background L90 noise level. The highest noise level exceedances are predicted for Scenario 14b which is associated with works in very close proximity to the mixed commercial/dwelling receptors situated south of the site

• the Noise Affected Management Level applicable at commercial and other sensitive receptors will be exceeded by up to 23 dB(A) at the most affected receptor. On average, and for the majority of receptors, noise levels will comply with the criteria for all assessed construction scenarios.

The predicted noise levels identified above are typical of construction works and activities undertaken in the vicinity of, and in close proximity to, residential and commercial precincts.


V

Although a number of exceedances are identified these are associated with predicted 15 minute noise values calculated via modelling for the purposes of the assessment, in accordance with the NSW Department of Environment and Climate Change – NSW Interim Construction Noise Guideline (ICNG), July 2009 and 7TP-ST-157/2.0. These values do not represent a constant noise emission that would be experienced by the community on a daily basis throughout the project schedule. The predicted noise levels will only be experienced for limited periods of time when works are occurring; they will not be experienced for full daytime, evening or night time periods.

Any impacts associated with these works will be temporary and do not represent a permanent impact on the community and surrounding environment.

Some noise from construction sites is inevitable, such that the ICNG focuses on minimising construction noise impacts, rather than only on achieving numeric noise levels. These results and noted exceedances identify that best-practice construction noise management and control techniques will be required to reduce noise levels as far as practicable. To minimise impacts additional noise control, mitigation and management measures are also warranted. These will need to be implemented in conjunction with a community and stakeholder consultation and notification processes.

TfNSW have developed their own best-practice techniques for managing construction noise and vibration, and implementing feasible and reasonable mitigation measures. These are documented in 7TP-ST-157/2.0 which also identifies the thresholds by which impacts can be qualified and the level of mitigation and management required for each stage of works. These thresholds also identify the level of community consultation required. The mitigation and management measures provided by TfNSW are consistent with the intent and recommendations of the INCG developed for managing construction noise and vibration, and implementing feasible and reasonable mitigation measures.

In accordance with the requirements of the ICNG and 7TP-ST-157/2.0 suitable recommendations, which can be practically implemented on site, are provided in Chapter 8. Construction noise levels will be reduced and impacts minimised with the successful implementation of these recommendations. Impacts may not be reduced to negligible levels for all receptors during all construction activities; however the recommendations are designed to ensure that any residual impacts are minimised as far as is practically achievable.

RECOMMENDATIONS

Based on these findings ERM has recommended construction noise and vibration control mitigation, management measures and/or monitoring options suitable for the significance of the predicted impacts and designed to minimise impacts as far as is feasible and reasonable.


VI

It is recommended that the standard noise mitigation measures and monitoring requirements presented in Section 6 of NSW Government – Transport for NSW (TfNSW) Construction Noise Strategy (7TP-ST-157/2.0), dated April 2013 be adopted for all works undertaken as part of the Proposal. The management, source control and path control measures applicable to air-borne noise should be implemented. Ground-borne noise impacts are not anticipated and therefore measures applicable to this acoustical factor do not apply. These measures will achieve the 8 dB noise level reduction applied to modelling completed for this assessment and will assist to reduce impacts associated with the works on the surrounding community.

It is recommended that TfNSW confirm the type and sensitivity of first floor receptors situated south and south-west of the site. Some locations south of the station were identified to be potentially of mixed use, with a commercial property (shop) on the ground floor, with potential residential (dwelling) receptors located above the shop on the first floor.

It is recommended that plant, equipment and machinery noise levels should not exceed the maximum allowable noise levels for construction equipment presented in Table 2 of 7TP-ST-157/2.0 or those presented in this report, whichever is the lowest value. This will insure that noise levels above those predicted here do not occur. Where values lower than those modelled are achieved, a noise level reduction to the predicted values presented in this report will occur. For example, if equipment is selected so that an overall reduction of 10 dB is achieved, then noise levels at nearby receptors will also reduce by approximately 10 dB.

It is recommended that the safe working distances for vibration intensive activities be applied to all works undertaken as part of the Proposal, where applicable. Importantly, where vibration intensive works are undertaken within 50m of a residential (dwelling) receptor an inspection of off-site vibration should be completed to determine if vibration levels are perceptible. If they are not perceptible, then no further action is required. If they are perceptible, then the management, source control and path control measures applicable to ground-borne vibration, or respite periods, should be implemented.

The assessment has identified that works undertaken outside the recommended standard hours for construction will generate potentially intrusive noise emissions with the potential to exceed the Noise Affected Management Levels. Section 8 of 7TP-ST-157/2.0 identifies a method by which additional mitigation measures may be considered and developed depending on the extent of the exceedance and comparison to existing background L90 noise levels.

Table E.2 presents a comparison of the highest predicted noise levels at residential (dwelling) receptors to the applicable assessment period background noise level. The exceedances are highlighted for applicable construction scenarios. The full set of resultant noise levels (for each receptor and scenario) are presented in Annex C of this assessment. Based on this set of results and the recommended additional mitigation measures that should apply according to Table 5 of the 7TP-ST-157/2.0, ERM has determined what measures will be required for each period and construction scenario. These findings are as presented in Table E.3.

CONCLUSION

No further recommendations for noise and vibration control, mitigation, management measures or monitoring options are provided for construction road traffic noise and vibration, and operational noise and vibration, to those already implemented.

Construction noise and vibration levels will be reduced and impacts minimised with the successful implementation of the recommendations provided in Chapter 8 of this report. Impacts may not be reduced to negligible levels for all receptors during all construction activities; however the recommendations presented here will ensure that any residual impacts are minimised as far as is practically achievable. No further recommendations to those presented in this report are provided.

1 INTRODUCTION

This report has been prepared by Environmental Resources Management Australia Pty Ltd (ERM) on behalf of Transport for NSW (TfNSW). It presents the methodology, findings and any recommendations for the noise and vibration impact assessment completed for construction and operational aspects of the Wentworthville Station Easy Access Upgrade (the Proposal).

1.1 PROJECT DESCRIPTION

The Proposal is part of the Transport Access Program (TAP), an initiative by TfNSW to provide a better experience for public transport customers by delivering accessible, modern, secure and integrated transport infrastructure where it is needed most. The main objectives of the TAP include:

• modern interchanges that support an integrated network and allow seamless transfers between all modes for all customers

• modern buildings and facilities for all modes that meet the needs of a growing population

• stations that are accessible to the disabled, ageing and parents with prams;

• safety improvements including extra lighting, help points, fences and security

• measures for car parks and interchanges, including stations, bus stops and wharves

• signage improvements so customers can more easily use public transport and transfer between modes at interchanges

• other improvements and maintenance such as painting, new fencing and roof replacements.

1.1.1 Proposed Works

The Proposal includes the following indicative key scope items:

• demolition of existing stairs and retail outlet

• services diversion and/or relocation to accommodate new infrastructure, including high voltage lines

• four new lifts and stairs at each new station entrance, and at both platforms

• canopies to stairs and entrance areas

• creation of a new concourse between platform lifts, including canopy over widened concourse and provisions for a future retail concession booth


2

• building modifications to provide accessible customer and staff areas/facilities including a new family accessible toilet and a new communications equipment room

• station power supply upgrade, adjustment to lighting, and augmentation of station communication systems associated with the new infrastructure

• modifications to passenger information systems and ticketing facilities

• station precinct upgrade and enhanced interchange provisions including adjustment to pedestrian crossing facilities at the Kingsway and Wentworth Avenue, access improvements such as footpath widening and kerb realignment, disability parking, kiss & ride parking, improvements to bus stand and taxi stand shelters, and bicycle parking facilities.

1.1.2 Proposed Hours for Construction

The standard NSW construction hours are:

• 0700 to 1800 Monday to Friday; 0800 to 1300 Saturday

• No work on Sundays and Public Holidays.

Construction works associated with the Proposal will generally be undertaken during the daytime period and within the recommended standard hours of construction. Some activities will be required outside these standard hours, to coincide with track possessions.

During track possessions, works will generally be undertaken on weekends with a limited number of activities required to be completed at night. Works that are required during track possessions are proposed to occur on approximately eight to twelve occasions over the 24 month construction period. When out of hours works are required, the highest noise or vibration generating activities will be carried out during the daytime where existing noise levels are the highest and people are less likely to be disrupted by noise and vibration from construction.

1.1.3 Justifying Out Of Hours Work

Where construction work has to be carried out in close proximity to an operational rail network (while simultaneously maintaining a safe working environment and minimising disruption to commuters) the need for work to be undertaken outside the standard hours often arises.

Construction work during standard daytime periods can be highly disruptive to commuter services and road traffic on major roads, as is the case for most infrastructure and transport projects.


3

In many cases, work that needs to be carried out safely in close proximity to the live rail network or station platforms can only be undertaken during periods of scheduled track work (i.e. track possessions) which are typically scheduled during periods of lower commuter use (i.e. overnight, weekends and holiday periods).

Additionally, where interfaces exist between transport projects and other transport (e.g. road) and utility (e.g. water, sewer, and telecommunications) infrastructure, construction during the standard hours may not be possible due to the need to avoid unacceptable impacts on traffic or water, power or communications services. For these reasons, it is desirable (or unavoidable) for the Proposal works work to be scheduled outside the standard hours.

1.1.4 Site Understanding

Wentworthville station is located approximately 26 km north-west of the Sydney Central Business District (CBD) and approximately 3 km north-west of Parramatta in NSW.

The station itself is bounded on Wentworth Avenue to the north and The Kingsway to the south with residential receptors to the north, the existing rail precinct to the east and some residential receptors, a mixed residential and commercial precinct to the south and residential receptors to the west and north-west.

The site and surrounding area, local area road network and other items of importance to this noise and vibration impact assessment are identified in Figure 1.1. This locality map also includes the receptors adopted for assessing noise and vibration levels; these are described in more detail in Chapter 2 of this report.

1.2 SCOPE OF THIS ASSESSMENT

To successfully assess noise and vibration associated with the Proposal, the following scope of work has been completed:

• review and validate relevant project data and information as considered relevant to the assessment scope

• review and confirm all potential receptors situated in the vicinity of potential project emission sources

• identify significant noise and vibration generating plant, equipment and/or activities associated with the project and their likely/known emissions and develop applicable assessment scenarios

• develop noise and vibration criteria in accordance with recognised NSW standards and guidelines as applicable to project activities

• complete a quantitative noise impact assessment by predicting project noise levels (via modelling) for the scenarios developed

• complete a quantitative vibration impact assessment by estimating project levels for the scenarios developed

• compare the resultant levels to the project-specific criteria or management levels at each receptor location and identify any exceedances and determine the magnitude and significance of any impacts

• recommend control mitigation, management measures and/or monitoring options suitable to the significance of the predicted impacts and designed to minimise impacts as far as is feasible and reasonable.

1.2.1 Construction Road Traffic – Noise and Vibration

ERM has reviewed the proposed construction road traffic requirements and potential temporary emission sources associated with the Proposal works to determine any potential impacts. This review focused on the location, route and quantity of vehicle movements and trips, and the likely change in acoustical environment that additional road traffic could generate.

This review has identified that construction road traffic associated with the Proposal is minimal when compared to existing traffic on surrounding public roads. Construction road traffic associated with the Proposal has limited or no potential to generate continuous elevated levels of noise and vibration at the closest and/or potentially most affected sensitive receptors or structures located off-site.

The magnitude and significance of any impacts assessed in accordance with the NSW Department of Environment, Climate Change and Water – NSW Road Noise Policy (RNP), March 2011 would be negligible, if any at all.


6

As such a quantitative assessment is not considered warranted for construction road traffic noise and vibration aspects of the Proposal and has been excluded from the assessment.

1.2.2 Operations – Noise and Vibration

ERM has reviewed the proposed operational emission sources associated with the Proposal to determine any potential impacts. This review focused on the location and potential emission of any new or upgraded sources, and the likely change in acoustical environment that the source could generate.

This review has identified that operational activities associated with the Proposal have limited or no potential to generate noise and vibration that would be perceptible at the closest and/or potentially most affected sensitive receptors or structures located off-site.

The magnitude and significance of any impacts assessed in accordance with the following guidelines would be negligible, if any at all:

• NSW Environment Protection Authority – NSW Environmental Noise Management – Industrial Noise Policy (INP), January 2000 and relevant application notes

• NSW Environment Protection Authority – NSW Rail Infrastructure Guideline (RIG), May 2013

• NSW Department of Environment, Climate Change and Water – NSW Road Noise Policy (RNP), March 2011

• German Institute for Standardisation – DIN 4150 (1999-02) Part 3 (DIN4150-3) – Structural Vibration - Effects of Vibration on Structures

• British Standard BS7385: Part 2-1993 (BS 7385) - Evaluation and Measurement for Vibration in Buildings — Part 2 – Guide to Damage Levels from Ground-borne Vibration, dated 1993

• NSW Department of Environment and Conservation – NSW Environmental Noise Management – Assessing Vibration: a Technical Guideline (the NSW Vibration Guideline), February 2006.

As such a quantitative assessment is not considered warranted for operational noise and vibration aspects of the Proposal and has been excluded from the assessment.

2 EXISTING ENVIRONMENT

This chapter describes the sensitive receptors that have been identified in proximity to the site; the measurement approach adopted to quantify existing levels representative of their location and measurement results; and the results of environmental noise measurements and logging.

All sound pressure levels presented in this chapter are in decibels referenced to 2 x 10-5 Pa.

2.1 SENSITIVE RECEPTORS

ERM has identified the following sensitive receptors to be the closest and/or potentially most affected locations situated in close proximity to Wentworthville station.

In each case ERM identified (during the preliminary acoustics survey of the site) where a property includes potential receptors in single or multiple storey buildings. Assessment heights of 1.5 metres, 4.5 metres, 7.5 metres, 10.5 metres, 13.5 metres and 16.5 metres have been utilised for predicting noise levels for single storey and up to six storey buildings. Importantly, some locations south of the station were identified to be potentially of mixed use, with a commercial property (shop) on the ground floor, with potential residential (dwelling) receptors located above the shop on the first floor. These locations are clearly highlighted.

These locations do not represent all potential receptors located in the vicinity of Wentworthville station but have been selected by ERM for the purposes of this impact assessment. These locations are considered to be representative of locations that will experience the highest impacts associated with the proposed upgrade works.

Construction noise and vibration associated with the Proposal works has been assessed at the locations and heights identified in Table 2.1. These same locations and their proximity to the site are identified as R1 to R31 in Figure 1.1 of Chapter 1.

2.2 EXISTING NOISE ENVIRONMENT

A key element in assessing environmental noise impacts is an understanding of the existing ambient and background noise levels in the vicinity of the closest and/or potentially most affected receivers situated in proximity to the site. The noise environment in the vicinity of existing residential and commercial receptors is best described as ‘urban’, being an area with an acoustical environment that:

• is dominated by ‘urban hum’ or industrial source noise

• has through traffic with characteristically heavy and continuous traffic flows during peak periods

• is near commercial districts or industrial districts

• has any combination of the above, where ‘urban hum’ means the aggregate sound of many unidentifiable, mostly traffic-related sound sources.

2.3 MEASUREMENT METHODOLOGY

In accordance with NSW noise guidelines, ambient and background noise levels are measured in the absence of the site under assessment and are used to develop noise criteria for residential receptors to which site noise level contributions (typically determined via modelling) are compared to1.

To quantify existing noise levels ERM conducted short-term operator attended noise measurements and long-term unattended noise logging at representative receptors, located near Wentworthville station.

The attended measurements and unattended logging were completed by trained ERM personnel (under the remote guidance of a qualified acoustics engineer) in accordance with the requirements specified in the NSW Environment Protection Authority – NSW Environmental Noise Management – Industrial Noise Policy (INP), January 2000 and relevant application notes; applicable parts of Standards Australia AS1055–1997™ (AS1055) – Description and Measurement of Environmental Noise and other relevant Australian and international standards for environmental noise monitoring.

1 Existing vibration levels are not required to be measured as vibration criteria are fixed values that do not depend on the existing conditions. This section focuses on the existing noise environment.


15

2.3.1 Short-Term Operator Attended Noise Measurements

Short-term operator attended noise measurements were completed at four locations around the site, identified as A1 to A4 in Figure 1.1 of Chapter 1. These locations were selected by the ERM operator whilst in the vicinity of the site (during a preliminary acoustical survey that was completed) to better understand the broader acoustical environment.

Each measurement was of 15 minutes duration and time synchronised to the noise logging device to allow for comparison of measured values at a range of acoustically different locations. The measurement device was set to show instantaneous noise levels throughout each measurement, which noise events noted by the operator and acoustical and statistical parameters recorded by the device at the end of the measurement. As a minimum Lmax, Lmin, Leq, L1, L10 and L90 values were captured.

2.3.2 Long-Term Unattended Noise Logging

Long-term unattended noise logging was completed at one location at a residential receptor situated in proximity to the site, identified as L1 in Figure 1.1 of Chapter 1. The logger was deployed on Tuesday, 3 November 2014 and collected on Tuesday, 11 November 2014, a total continuous logging period of approximately eight days.

This location was selected by the ERM operator whilst in the vicinity of the site and during a preliminary acoustical survey that was completed. This location was preferred for logging as it allowed the measurement of existing ambient and background noise levels that are considered representative of the broader acoustical environment at the majority of residential receptors situated in close proximity to Wentworthville station.

The logging device was set to record acoustical and statistical parameters at 15 minute intervals for a period of ten days. As a minimum Lmax, Lmin, Leq, L1, L10 and L90 values were captured.

At the conclusion of logging the captured noise data was combined with meteorological data from the nearest Bureau of Meteorology (BOM) Automated Weather Station (AWS) to exclude any values that exceeded the rain and wind thresholds for noise logging analysis. The nearest BOM AWS is situated at Sydney Olympic Park (Archery Centre (ID: 66212)) and measures meteorological data at a height of 22 metres above ground level. As such, any data recorded during periods of rain or when wind speeds that exceeded 7.5m/s (approximately equal to 5m/s at microphone height, 1.5 metres above ground level) has been excluded.


16

2.3.3 Measurement and Logging Equipment

The measurement and logging equipment used to complete the assessment complied with the requirements of Standards Australia AS IEC 61672.1–2004™ (AS61672) – Electro Acoustics - Sound Level Meters Specifications Monitoring or Standards Australia AS1259.2-1990™ (AS1259) – Acoustics – Sound Level Meters – Integrating/Averaging as necessary.

Each device had current National Association of Testing Authorities, Australia (NATA) calibration certificates, with certification at intervals not exceeding two years at the time of use.

The equipment used for this assessment was as follows:

• 1 x SVANTECH 957 (Type 1) Sound Level Meter

• 1 x Brüel & Kjær 2250 (Type 1) Sound Level Meter

• 1 x ARL Ngara (Type 1) Environmental Noise Logger

• 1 x SVANTECH (Type 1) Sound Level Calibrator

• 1 x Brüel & Kjær (Type 1) Sound Level Calibrator.

Instrument calibration was checked prior to monitoring and again at the conclusion with no difference noted between the two measurements. The sound level calibrator used complied with the requirements of Standards Australia AS/IEC 60942:2004/IEC 60942:2003 (IEC60942) – Australian Standard™ – Electroacoustics – Sound Calibrators.

2.4 MEASURED EXISTING NOISE LEVELS

This section presents the measured noise levels from short-term operator attended noise measurements and long-term unattended noise logging completed adopting the methodology described above.

2.4.1 Operator Attended Noise Measurement Results

The results of short-term operator attended noise measurements completed on Tuesday, 4 November and Tuesday, 11 November are presented in Table 2.2. Each measurement was time synchronised to the noise logging device and a comparison of measured L90 values is provided to validate the logging data for the broader community.

Discussion

The measured ambient and background noise levels presented in Table 2.2 vary significantly, which is to be expected in an urban or suburban environment with existing traffic and industrial/commercial emissions sources. These sources dominated the acoustical environment at the majority of locations, with other sources of noise observed such as wind-blown vegetation, domestic animals, residential activities, airplanes passing overhead. Meteorological conditions were generally calm with light winds for the majority of measurements.

Comparing the measured L90 from operator attended noise measurements to the measured (time synchronised) L90 from unattended noise logging identifies that background noise levels were generally lower at the logger location, than at other locations within the broader community. Therefore, no correction has been applied to the measured overall noise levels presented in Section 2.4.2. The noise logging data is conservatively is representative of the majority of the community.


18

2.4.2 Unattended Noise Logging Results

The results of long-term unattended noise logging completed between Tuesday, 3 November 2014 and Tuesday, 11 November 2014 are presented in Table 2.3.

ERM notes that, following exclusion of data due to wind and rain, only six samples were captured for the daytime period. Given the dominance of existing transportation noise, and existing commercial and industrial emission sources this is not considered significant.

Noise Logging Charts

Noise logging charts which visually present the noise data captured in 15 minute samples (and meteorological data used to exclude any erroneous samples) are provided in Annex B.

All sound power levels presented in this report (e.g. noise levels assigned to specific sources) are decibels referenced to 10-12W.

3.2 POLICY SETTING

In NSW, noise pollution is regulated through the Protection of the Environment Operations Act 1997 (POEO Act) as the key piece of environment protection legislation. Noise pollution is defined under the POEO Act as:

‘the emission of offensive noise, which means noise that by reason of its level, nature, character or quality, or the time at which it is made, or any other circumstances, is harmful (or is likely to be harmful) to or interferes unreasonably (or is likely to interfere unreasonably) with the comfort or repose of a person outside the premises from which the noise is emitted’.

Under the POEO Act, the ‘POEO (Noise Control) Regulation 2008’ addresses common noisy activities that occur in residential situations; it limits the time of day that noisy articles (such as lawn mowers, stereos and leaf blowers) are permitted to be heard in neighbouring residences, however it does not specify noise limits and an applicable approach for the assessment of existing sites.

Various noise and vibration assessment guidelines endorsed by NSW regulators provide a guideline framework and methodology for deriving acceptable levels and standard methods for assessing and measuring construction impacts with due regard to the POEO Act.

3.2.1 Relevant Documents, Standards and Guidelines

This assessment has been undertaken with due regard to and in accordance with the following documents, standards and guidelines:

• NSW Department of Environment and Climate Change – NSW Interim Construction Noise Guideline (ICNG), July 2009

• NSW Government – Transport for NSW (TfNSW) Construction Noise Strategy (7TP-ST-157/2.0), dated April 2013


20

• Standards Australia AS 2436–2010™ (AS2436) – Guide to Noise and Vibration Control on Construction, Demolition and Maintenance Sites

• British Standard BS7385: Part 2-1993 (BS 7385) - Evaluation and Measurement for Vibration in Buildings — Part 2 – Guide to Damage Levels from Ground-borne Vibration, dated 1993



3.2.2 EPA – Interim Construction Noise Guideline

The NSW Department of Environment and Climate Change – NSW Interim Construction Noise Guideline (ICNG), July 2009 presents an accepted method by which construction noise and vibration impacts may be assessed for a range of receptor types for works completed in NSW.

The ICNG focuses on minimising construction noise impacts, rather than only on achieving numeric noise levels, and recognises that some noise from construction sites is inevitable. The ICNG encourages organisations involved with construction, maintenance or upgrading works (such as transport projects) to develop their own best-practice techniques for managing construction noise and vibration, and implementing feasible and reasonable mitigation measures.

3.2.3 TfNSW – Construction Noise Strategy

The NSW Government – Transport for NSW (TfNSW) Construction Noise Strategy (7TP-ST-157/2.0), dated April 2013, was developed to address the assessment requirements documented in the ICNG. Document 7TP-ST-157/2.0 also identifies the thresholds by which impacts can be qualified and the level of mitigation and management that is required for each stage of works.

The mitigation and management measures provided by TfNSW are consistent with the intent and recommendations of the INCG for own best-practice techniques to be developed for managing construction noise and vibration, and implementing feasible and reasonable mitigation measures.

3.3 NOISE MODELLING

Brüel & Kjær’s Predictor 7810 (Version 8.14) noise modelling software package was utilised to calculate noise levels using the International Organisation for Standardisation (ISO) 9613-2:1996 (ISO9613:2) - Acoustics - Attenuation of Sound during Propagation Outdoors - Part 2: General Method of Calculation noise propagation algorithms (international method for general purpose, 1/1 octaves). For sound calculated using the ISO9613 standard, the indicated accuracy is ±3dBA at source to receiver distances of up to 1000m and unknown at distances above 1000m.

The Predictor software package allows topographic details to be combined with ground regions, water, grass, significant building structures etc. and project-specific assessment locations, to create a detailed and accurate representation of the site and surrounding area.

The noise model allowed for the quantification of noise levels from multiple sources, based on sound pressures or sound pressure levels emitted from each. The model computed the noise propagation in the assessment area of influence to specifically quantify A-weighted decibels, dBA.

The construction noise model was developed to include likely noise emission sources associated with the twelve construction scenarios described in Chapter 2.

3.4 VIBRATION PREDICTIONS

As is apparent in the relevant standards and guidelines for evaluating the effect of vibration on humans or structures, there is no defined calculative process that may be followed to precisely predict vibration levels at a given assessment location.

Unlike noise which travels through air, the transmission of vibration is highly dependent on substratum conditions between the source/s and receiver. Also dissimilar to noise travelling through air, vibration levels diminish quickly over distance, thus an adverse impact from vibration on the broader community is not typically expected.

Vibration levels in this case have been estimated via calculation based on the proposed construction activities and plant that are likely to be in use. These predictions have been made for a range of representative source to receiver distances to assess impacts; and inform mitigation and management measures and safe work distances for intensive activities.


22

3.4.1 Calculative Method

Vibration calculations have been made with reference to measured test vibration events and levels from the ERM database, as identified in Figure 3.1.

These test values are calibrated to the known project plant, equipment and/or activities under assessment, and allow project vibration levels to be extrapolated from the source (closest Project emission area) to the assessment distance. The following ERM vibration test data and extrapolation equations were used prior to a calibration factor being selected and applied.

Figure 3.1 ERM Vibration Test Data

Guidance Note

Unlike noise, vibration attenuates quickly over distance. Structural damage impacts are not typically anticipated for receivers at distances greater than 50 metres. Furthermore human annoyance impacts are not typically anticipated for receivers at distances greater than 100 metres.

4 PROJECT–SPECIFIC MANAGEMENT LEVELS

This chapter presents the project-specific noise management levels and vibration criteria that have been adopted to assess potential construction impacts at off-site receptors.

4.1 CONSTRUCTION NOISE MANAGEMENT LEVELS

The project-specific ‘Noise Affected Management Levels’ have been determined with due regard to the NSW Department of Environment and Climate Change – NSW Interim Construction Noise Guideline (ICNG), July 2009 utilising the measured ambient and background noise levels described in Chapter 2 for residential receptors.

The ‘Highly Noise Affected Management Level’ also applies to residential receptors during standard daytime hours and is a fixed value of 75 dB(A). The remaining noise management levels were developed for each sensitive receptor type as applicable.

All project-specific noise management levels identified in Table 4.1, each value is expressed as the LAeq, 15 minute noise level parameter.

4.2 CONSTRUCTION VIBRATION CRITERIA

The project-specific vibration criteria have been determined with due regard to the:



ERM also considered British Standard BS7385: Part 2-1993 (BS 7385) - Evaluation and Measurement for Vibration in Buildings — Part 2 – Guide to Damage Levels from Ground-borne Vibration, dated 1993. However DIN 4150-3 provides a more conservative method by which structural damage can be assessed. Compliance with DIN4150-3 structural damage guideline values also identifies compliance with the BS 7385 transient vibration guide values for cosmetic damage.

All project-specific vibration criteria are identified in Table 4.2 to Table 4.4. The full set of structural damage guideline values are identified in Figure 4.1, which illustrates the frequency versus velocity scale that applies to the assessment of vibration in accordance with DIN4150-3.

5 ASSESSMENT SCENARIOS

Assessment scenarios have been developed based on the 39 construction activities described in Chapter 1. The plant, equipment, and/or machinery with the potential to generate noise and vibration impacts at the closest and/or potentially most affected sensitive receptors or structures located off-site have been considered in each case.

The 39 construction assessment scenarios are identified in Table 5.1 and have been adopted for the purposes of predicting noise levels and estimating vibration and comparison to management levels and criteria. The scheduled works required during standard construction hours only or works required during standard hours or during track possession are highlighted.

Table 5.1 also presents the ‘Sound Power Level’ (LW) allocated to each item of equipment and the overall fleet LW value is summarised in Table 5.2. This source data has been has been determined based on actual or representative LW data from the maximum permissible values presented in the NSW Government – Transport for NSW (TfNSW) Construction Noise Strategy (7TP-ST-157/2.0), dated April 2013. Where data from 7TP-ST-157/2.0 did not accurately describe the equipment or activity being undertaken, the maximum values from Standards Australia AS 2436–2010™ (AS2436) – Guide to Noise and Vibration Control on Construction, Demolition and Maintenance Sites have been adopted.

Sound Power Level (LW) is a measure of the total power radiated by a source. The Sound Power of a source is a fundamental property of the source and is independent of the surrounding environment. This differs from Sound Pressure Level (LP) which is the level of sound pressure; as measured at a distance by a standard sound level meter with a microphone. This differs from LW in that this is the received sound as opposed to the sound ‘intensity’ at the source.

6 NOISE ASSESSMENT

The chapter presents the noise assessment completed for the proposed construction works associated with the Proposal.

6.1 PREDICTED CONSTRUCTION NOISE LEVELS

A summary of predicted construction noise levels for residential and other sensitive receptors is presented in Table 6.1 to Table 6.3 for each assessment scenario.

Preliminary (unmitigated) noise modelling was first completed and then an overall 8 dB reduction in noise levels incorporated into the model. This value was determined following review of the standard mitigation measures described in the NSW Government – Transport for NSW (TfNSW) Construction Noise Strategy (7TP-ST-157/2.0), dated April 2013, which are required for all transport projects.

This 8 dB value was determined for the Proposal works by comparing the average of maximum, mid-point and minimum noise emission values presented in Standards Australia AS 2436–2010™ (AS2436) – Guide to Noise and Vibration Control on Construction, Demolition and Maintenance Sites for similar types of plant and equipment that are proposed to be used as part of the Proposal. This approach has been adopted to accurately estimate the likely effect of all project-specific and standard 7TP-ST-157/2.0 mitigation measures in the noise model.

For each scenario the lowest predicted value, arithmetic average of predicted values and highest predicted value is presented to provide a simplified discussion of results. The results are presented for residential (dwelling) receptors and for all other sensitive receptors. Predicted values are compared to the applicable Noise Affected Management Levels for residential receptors and other sensitive receptors to determine any exceedances and to inform any recommendations.

The full set of predicted LAeq, 15 minute noise levels is presented in Annex C. Noise contour maps for Scenario 4 (which is predicted to generate the highest average noise level, potentially affecting the most receptors) and Scenario 14b (which is predicted to generate the highest noise levels at any receptor) are presented in Figure 6.1 and Figure 6.2.

6.2 SUMMARY OF FINDINGS

The results presented in Table 6.1 to Table 6.3 identify the following:

• the daytime Noise Affected Management Level (50 dB) applicable at residential (dwelling) receptors for works within the recommended standard hours of construction will be exceeded by up to 41 dB(A) at the most affected receptor, which is 51 dB(A) above the daytime background L90 noise level. On average, noise levels will exceed this criteria by up to 16 dB for all assessed construction scenarios

• for 21 of the 56 assessed scenarios and construction areas, the Highly Noise Affected Management Level (75 dB) applicable at residential (dwelling) receptors during the daytime will be exceeded by up to 16 dB(A) at the most affected receptor

• the daytime Noise Affected Management Level (45 dB) applicable at residential (dwelling) receptors for works outside the recommended standard hours of construction will be exceeded by up to 46 dB(A) at the most affected receptor, which is 51 dB(A) above the daytime background L90 noise level. On average, noise levels will exceed this criteria by up to 21 dB for all assessed construction scenarios

• the evening Noise Affected Management Level (43 dB) applicable at residential (dwelling) receptors for works outside the recommended standard hours of construction will be exceeded by up to 48 dB, which is 53 dB(A) above the evening background L90 noise level

• the night time Noise Affected Management Level (38 dB) applicable at residential (dwelling) receptors for works outside the recommended standard hours of construction will be exceeded by up to 53 dB, which is approximately 58 dB(A) above the night time background L90 noise level. The highest noise level exceedances are predicted for Scenario 14b which is associated with works in very close proximity to the mixed commercial/dwelling receptors situated south of the site

• the Noise Affected Management Level applicable at commercial and other sensitive receptors will be exceeded by up to 23 dB(A) at the most affected receptor. On average and for the majority of receptors, noise levels will comply with the criteria for all assessed construction scenarios.

6.2.1 Discussion

The predicted noise levels identified above are typical of construction works and activities undertaken in the vicinity of and in close proximity to residential and commercial precincts.

Although a number of exceedances are identified these are associated with predicted 15 minute noise values calculated via modelling for the purposes of the assessment, in accordance with the NSW Department of Environment and Climate Change – NSW Interim Construction Noise Guideline (ICNG), July 2009 and 7TP-ST-157/2.0. These values do not represent a constant noise emission that would be experienced by the community on a daily basis throughout the project schedule. The predicted noise levels will only be experienced for limited periods of time when works are occurring; they will not be experienced for full daytime, evening or night time periods.

Any impacts associated with these works will be temporary and do not represent a permanent impact on the community and surrounding environment.

Some noise from construction sites is inevitable, such that the ICNG focuses on minimising construction noise impacts, rather than only on achieving numeric noise levels. These results and noted exceedances identify that best-practice construction noise management and control techniques will be required to reduce noise levels as far as practicable. To minimise impacts additional noise control, mitigation and management measures are also warranted. These will need to be implemented in conjunction with a community and stakeholder consultation and notification processes.

TfNSW have developed their own best-practice techniques for managing construction noise and vibration, and implementing feasible and reasonable mitigation measures. These are documented in 7TP-ST-157/2.0 which also identifies the thresholds by which impacts can be qualified and the level of mitigation and management required for each stage of works. These thresholds also identify the level of community consultation required. The mitigation and management measures provided by TfNSW are consistent with the intent and recommendations of the INCG for developed for managing construction noise and vibration, and implementing feasible and reasonable mitigation measures.

In accordance with the requirements of the ICNG and 7TP-ST-157/2.0 suitable recommendations, which can be practically implemented on site, are provided in Chapter 8. Construction noise levels will be reduced and impacts minimised with the successful implementation of these recommendations. Impacts may not be reduced to negligible levels for all receptors during all construction activities; however the recommendations are designed to ensure that any residual impacts are minimised as far as is practically achievable.

7 VIBRATION ASSESSMENT

The chapter presents the vibration assessment completed for the proposed construction works associated with the Proposal.

Broadly, the resultant vibration levels (at distance from the source) align with the safe work distances for vibration intensive plant, as presented in the NSW Government – Transport for NSW (TfNSW) Construction Noise Strategy (7TP-ST-157/2.0), dated April 2013.

These results identify that vibration management measures are warranted for the construction works occurring in close proximity to receptors. Suitable recommendations, which can be practically implemented on site, are provided in Chapter 8. Further discussion of the results is provided below.

7.1 PREDICTED PPV VIBRATION VALUES

Peak Particle Velocity (PPV) refers to the instantaneous value of the distance travelled by a particle per unit time in a medium that is displaced from its equilibrium state by the passage of a sound or vibration wave. It is expressed using the ‘mm/s’ parameter. In this case the highest particle velocity for a particular vibration event over the three standard measurement axes is provided.

ERM has calculated Peak Particle Velocity (PPV) levels for potential vibration generating activities as identified in Table 7.1. In this case these potential activities are limited to jackhammering and an excavator (20 tonne) with hammer attachment, both associated with upgrade works. These are the only activities with the potential to generate impacts. ERM has adopted a conservative approach to predicting vibration levels, which means there is no significant difference in estimated values anticipated between jackhammering and excavator hammering works.

These predictions were based on the assessment methodology described in Chapter 3 and the type of plant, equipment and machinery presented in Chapter 5 for each of the construction assessment scenarios.

7.2 HUMAN COMFORT (IMPULSIVE VIBRATION) AND STRUCTURAL DAMAGE

Perceptible vibration levels refer to the value at which a receiver or building occupant may ‘feel’ the vibration generated by an activity and 0.2mm/s is typically considered to be the human threshold for perception of vibration.

The results presented above identify that the potential for perceptible levels of vibration to occur is minimal for works more than 50 metres from a receptor. Where works are completed within 50 metres of a receptor, perceptible levels of vibration may be generated but will remain below the:

• human comfort limiting impulsive criteria – minimum criteria value of 2.8mm/s for residences at night time

• structural damage limiting criteria – minimum criteria value of 3mm/s for dwellings and buildings of similar design and/or use.

7.2.1 Human Comfort (Intermittent Vibration)

It is also important to consider potential impacts associated which intermittent vibration events which occur frequently throughout an assessment period. Intermittent vibration is assessed using a Vibration Dose Value (VDV), which is a concept outlined in NSW Department of Environment and Conservation – NSW Environmental Noise Management – Assessing Vibration: a Technical Guideline (the NSW Vibration Guideline), February 2006.


57

VDV is a calculative approach to assessing the impact of intermittent vibration or extended periods of impulsive vibration. VDV requires the measurement of the overall weighted RMS (Root Mean Square) acceleration levels over the frequency range 1Hz to 80Hz. To calculate VDV the following formula is used:

25.0

0

4 )(

= ∫

T

dttaVDV

Where VDV is the vibration dose value in m/s1.75, a (t) is the frequency-weighted RMS of acceleration in m/s2 and T is the total period of the day (in seconds) during which vibration may occur.

Predictions for VDV are possible however they have an inherent level of uncertainty due to the number of calculative elements, which are difficult to determine for a quantitative impact assessment.

To provide a quantitative assessment ERM has selected three potential scenarios for vibration events. The purpose of this assessment is to identify that with management of vibration generating activities, impacts can be reduced to negligible levels.

The resultant VDV levels are presented in Table 7.2.

Discussion

The results presented in Table 7.2 identify that with the implementation of the safe work distances for vibration intensive plant, as presented in 7TP-ST-157/2.0 and with suitable management measures to control and limit perceptible vibration events, impacts will be minimal and site works will be able to comply with the preferred VDV guideline values (m/s1.75) applicable to intermittent vibration.

7.3 GROUND-BORNE NOISE

Based on the type of plant and equipment proposed to be use, the predicted vibration levels presented above and the type of activities that are required to be undertaken as part of the Proposal, it is unlikely that ground-borne noise will be generated. Impacts associated with this acoustical factor (that is typically associated with tunnel boring works etc.) are not anticipated.

8 RECOMMENDATIONS

This chapter presents any recommendations for noise or vibration control mitigation, management measures or monitoring options.

ERM has qualitatively assessed potential impacts associated with construction road traffic noise and vibration, and operational noise and vibration. No impacts are anticipated and as such no further recommendations for noise and vibration control, mitigation, management measures or monitoring options are provided here, to those already implemented.

The focus of this chapter is construction noise and vibration associated with the Proposal that have the potential to generate impacts at the closest and/or potentially most affected sensitive receptors or structures located off-site.

8.1 CONSTRUCTION NOISE & VIBRATION OBJECTIVES

The overall objective of construction noise and vibration management is to limit impacts on nearby receptors. This can be achieved by implementing the requirements of the NSW Government – Transport for NSW (TfNSW) Construction Noise Strategy (7TP-ST-157/2.0), dated April 2013 which reflects the intent and purpose of the NSW Department of Environment and Climate Change – NSW Interim Construction Noise Guideline (ICNG), July 2009.

Therefore, the following hierarchical approach should be used as far as practicable:

• where site noise levels are above goals or criteria, implement reasonable and feasible good practice environmental controls to minimise noise and vibration emissions and/or exposure duration at affected receptors

• where the use of best practice environmental control mitigation measures do not adequately address exceedances of goals or criteria, adopt alternative measures to minimise impacts on the community

• liaise with the local community regarding scheduled works which are predicted to have increased impacts.

8.2 STANDARD MITIGATION MEASURES AND MONITORING REQUIREMENTS

It is recommended that the standard noise mitigation measures and monitoring requirements presented in Section 6 of 7TP-ST-157/2.0 be adopted for all works undertaken as part of the Proposal. The management, source control and path control measures applicable to air-borne noise should be implemented. Ground-borne noise impacts are not anticipated and therefore measures applicable to this acoustical factor do not apply do not apply. These measures will achieve the 8 dB noise level reduction applied to modelling and


61

will assist to reduce impacts associated with the works on the surrounding community.

It is recommended that TfNSW confirm the type and sensitivity of first floor receptors situated south and south-west of the site. ERM reiterates some locations south of the station were identified to be potentially of mixed use, with a commercial property (shop) on the ground floor, with potential residential (dwelling) receptors located above the shop on the first floor.

It is recommended that plant, equipment and machinery noise levels should not exceed the maximum allowable noise levels for construction equipment presented in Table 2 of 7TP-ST-157/2.0 or those presented in this report, whichever is the lowest value. This will insure that noise levels above those predicted here do not occur. Where values lower than those modelled are achieved a noise level reduction to the predicted values presented in this report will occur. For example, if equipment is selected so that an overall reduction of 10 dB is achieved, then noise levels at nearby receptors will also reduce by approximately 10 dB.

It is recommended that the safe working distances for vibration intensive activities be applied to all works undertaken as part of the Proposal, where applicable. Importantly, where vibration intensive works are undertaken within 50m of a residential (dwelling) receptor an inspection of off-site vibration should be completed to determine if vibration levels are perceptible. If they are not perceptible, then no further action is required. If they are perceptible, then the management, source control and path control measures applicable to ground-borne vibration, or respite periods, should be implemented.

8.3 APPLYING ADDITIONAL MITIGATION MEASURES

The assessment has identified that works undertaken outside the recommended standard hours for construction will generate potentially intrusive noise emissions with the potential to exceed the Noise Affected Management Levels. Section 8 of 7TP-ST-157/2.0 identifies a method by which additional mitigation measures may be considered and developed depending on the extent of the exceedance and comparison to existing background L90 noise levels.

Table 8.1 presents a comparison of the highest noise levels predicted at residential (dwelling) receptors for each assessment scenario to the applicable assessment period background noise level. Construction scenarios which are predicted to generate noise levels be within the four mitigation ranges are listed. Based on this set of results and the recommended additional mitigation measures that should apply according to Table 5 of the 7TP-ST-157/2.0, ERM has determined what measures will be required for each period and construction scenario. These findings are as presented in Table 8.2.

9 CONCLUSION

ERM was engaged by TfNSW to complete a noise and vibration impact assessment for construction and operational aspects of the Proposal as part of the Transport Access Program (TAP), an initiative by TfNSW to provide a better experience for public transport customers by delivering accessible, modern, secure and integrated transport infrastructure where it is needed most.

The assessment was completed to achieve a scope of works that allowed for the successful identification of potential receptors situated in the vicinity of site emission sources and identification of significant noise and vibration generating plant, equipment and/or activities associated with the project and their likely/known emissions. ERM quantified existing ambient and background noise levels in the area and developed noise and vibration criteria in accordance with recognised NSW standards and guidelines as applicable to the project activities, and developed applicable assessment scenarios.

ERM qualitatively assessed potential impacts associated with construction road traffic noise and vibration, and operational noise and vibration; no impacts are anticipated. A quantitative construction noise and vibration impact assessment was then completed by predicting noise levels via modelling and by estimating vibration levels based on ERM test data. The predictions were completed for applicable assessment scenarios. Resultant noise and vibration levels were then compared to project-specific criteria or management levels at each receptor location and any exceedances identified. Based on these findings ERM has recommended noise and vibration control mitigation, management measures and/or monitoring options suitable to the significance of the predicted impacts and designed to minimise impacts as far as is feasible and reasonable.

No further recommendations for noise and vibration control, mitigation, management measures or monitoring options are provided for construction road traffic noise and vibration, and operational noise and vibration, to those already implemented.

Construction noise and vibration levels will be reduced and impacts minimised with the successful implementation of the recommendations provided in Chapter 8 of this report. Impacts may not be reduced to negligible levels for all receptors during all construction activities; however the recommendations presented here will ensure that any residual impacts are minimised as far as is practically achievable. No further recommendations to those presented in this report are provided.

Acoustics Glossary


A1

A.1 ACOUSTICS - GLOSSARY OF TERMS, DEFINITIONS AND METHODOLOGY

A.1.1 What Is Noise And Vibration?

Noise

Noise is often defined as a sound, especially one that is loud or unpleasant or that causes disturbance2 or simply as unwanted sound, but technically, noise is the perception of a series of compressions and rarefactions above and below normal atmospheric pressure.

Vibration

Vibration refers to the oscillating movement of any object. In a sense noise is the movement of air particles and is essentially vibration, though in regards to an environmental assessment vibration is typically taken to refer to the oscillation of a solid object(s). The impact of noise on objects can lead to vibration of the object, or vibration can be experienced by direct transmission through the ground, this is known as ground-borne vibration.

Essentially, noise can be described as what a person hears, and vibration as what they feel.

A.1.2 What Factors Contribute To Environmental Noise?

The noise from an activity, like construction works, at any location can be affected by a number of factors, the most significant being:

• how loud the activity is

• how far away the activity is from the receiver

• what type of ground is between the activity and the receiver location e.g. concrete, grass, water or sand

• how the ground topography varies between the activity and the receiver (is it flat, hilly, mountainous) as blocking the line of sight to a noise source will generally reduce the level of noise

• any other obstacles that block the line of sight between the source to receiver e.g. buildings or purpose built noise walls.

A.1.3 How To Measure And Describe Noise?

Noise is measured using a specially designed ‘sound level’ meter which must meet internationally recognised performance standards. Audible sound pressure levels vary across a range of 107 Pascals (Pa), from the threshold of hearing at 20µPa to the threshold of pain at 200Pa. Scientists have defined a statistically described logarithmic scale called Decibels (dB) to more manageably describe noise.

To demonstrate how this scale works, the following points give an indication of how the noise levels and differences are perceived by an average person:

• 0 dB - represents the threshold of human hearing (for a young person with ears in good condition)

• 50 dB – represents average conversation

• 70 dB – represents average street noise, local traffic etc.

• 90 dB – represents the noise inside an industrial premises or factory

• 140 dB - represents the threshold of pain – the point at which permanent hearing damage may occur.

A.1.4 Human Response to Changes in Noise Levels

The following concepts offer qualitative guidance in respect of the average response to changes in noise levels:

• differences in noise levels of less than approximately 2 dB(A) are generally imperceptible in practice, an increase of 2 dB is hardly perceivable

• differences in noise levels of around 5 dB(A) are considered to be significant

• differences in noise levels of around 10 dB(A) are generally perceived to be a doubling (or halving) of the perceived loudness of the noise. An increase of 10 dB is perceived as twice as loud. Therefore an increase of 20 dB is four times as loud and an increase of 30 dB is eight times as loud etc

• the addition of two identical noise levels will increase the dB level by about 3 dB. For example, if one car is idling at 40 dB and then another identical car starts idling next to it, the total dB level will be about 43 dB

• the addition of a second noise level of similar character which is at least 8 dB lower than the existing noise level will not add significantly to the overall dB level


A3

• a doubling of the distance between a noise source and a receiver results approximately in a 3 dB decrease for a line source (for example, vehicles travelling on a road); and a 6 dB decrease for a point source (for example, the idling car discussed above). A doubling of traffic volume for a line source results approximately in a 3 dB increase in noise, halving the traffic volume for a line source results approximately in a 3 dB decrease in noise.

A.1.5 Terms To Describe The Perception Of Noise

The following terms offer quantitative and qualitative guidance in respect of the audibility of a noise source:

• Inaudible / Not Audible - the noise source and/or event could not be heard by the operator, masked by extraneous noise sources not associated with the source. If a noise source is ‘inaudible’ its noise level may be quantified as being less than the measured LA90 background noise level, potentially by 10 dB or greater

• Barely Audible – the noise source and/or event are difficult to define by the operator, typically masked by extraneous noise sources not associated with the source. If a source is ‘barely audible’ its noise level may be quantified as being 5 - 7 dB below the measured LA90 or LAeq noise level, depending on the nature of the source e.g. constant or intermittent

• Just Audible – the noise source and/or event may be defined by the operator. However there are a number of extraneous noise sources contributing to the measurement. The noise level should be quantified based on instantaneous noise level contributions, noted by the operator

• Audible - the noise source and/or event may be easily defined by the operator. There may be a number of extraneous noise sources contributing to the measurement. The noise level should be quantified based on instantaneous noise level contributions, noted by the operator

• Dominant – the noise source and/or event are noted by the operator to be significantly ‘louder’ than all other noise sources. The noise level should be quantified based on instantaneous noise level contributions, noted by the operator.

The following terms offer qualitative guidance in respect of acoustic terms used to describe the frequency of occurrence of a noise source during an operator attended environmental noise measurements:

• Constant – this indicates that the operator has noted the noise source(s) and/or event to be constantly audible for the duration of the noise measurement e.g. an air-conditioner that runs constantly during the measurement


A4

• Intermittent – this indicates that the operator has noted the noise source(s) and/or event to be audible, stopping and starting intervals for the duration of the noise measurement e.g. car pass-bys

• Infrequent – this indicates that the operator has noted the noise source(s) and/or event to be constantly audible, however; not occurring regularly or at intervals for the duration of the noise measurement e.g. a small number of aircraft are noted during the measurement.

A.1.6 How To Calculate Or Model Noise Levels?

There are two recognised methods which are commonly adopted to determine the noise at particular location from a proposed activity. The first is to undertake noise measurements whilst the activity is in progress and measure the noise, the second is to calculate the noise based on known noise emission data for the activity in question.

The second option is preferred as the first option is largely impractical in terms of cost and time constraints, notwithstanding the meteorological factors that may also influence its quantification. Furthermore, it is also generally considered unacceptable to create an environmental impact simply to measure it. In addition, the most effective mitigation measures are determined and implemented during the design phase and often cannot be readily applied during or after the implementation phase of a project.

Because a number of factors can affect how ‘loud’ a noise is at a certain location, the calculations can be very complex. The influence of other ambient sources and the contribution from a particular source in question can be difficult to ascertain. To avoid these issues, and to quantify the direct noise contribution from a source/site in question, the noise level is often calculated using noise modelling software packages. The noise emission data used in each noise model of this assessment has been obtained from ERM’s database of measured noise emissions.

A.1.7 Acoustic Terminology & Statistical Noise Descriptors

Environmental noise levels such as noise generated by industry, construction and road traffic are commonly expressed in dB(A). The A-weighting scale follows the average human hearing response and enables comparison of the intensity of noise with different frequency characteristics. Time varying noise sources are often described in terms of statistical noise descriptors. The following descriptors are commonly used when assessing noise and are referred to throughout this acoustic assessment:

• Decibel (dB is the adopted abbreviation for the decibel) – The unit used to describe sound levels and noise exposure. It is equivalent to 10 times the logarithm (to base 10) of the ratio of a given sound pressure to a reference pressure


A5

• dB(A) - unit used to measure ‘A-weighted’ sound pressure levels. A-weighting is an adjustment made to sound-level measurement to approximate the response of the human ear

• dB(C) – unit used to measure ‘A-weighted’ sound pressure levels. C-weighting is an adjustment made to sound-level measurements which takes account of low-frequency components of noise within the audibility range of humans

• dB(Z) or dB(L) – unit used to measure ‘Z-weighted’ sound pressure levels with no weighting applied, linear

• Hertz (Hz) - the measure of frequency of sound wave oscillations per second. 1 oscillation per second equals 1 hertz

• Octave – a division of the frequency range into bands, the upper frequency limit

• 1/3 Octave – single octave bands divided into three parts

• Leq - this level represents the equivalent or average noise energy during a measurement period. The Leq, 15min noise descriptor simply refers to the Leq noise level calculated over a 15 minute period. Indeed, any of the below noise descriptors may be defined in this way, with an accompanying time period (e.g. L10, 15 minute) as required

• Lmax - the absolute maximum noise level in a noise sample

• LN - the percentile sound pressure level exceeded for N% of the measurement period calculated by statistical analysis

• L10 - the noise level exceeded for 10 per cent of the time and is approximately the average of the maximum noise levels

• L90 - the noise level exceeded for 90 per cent of the time and is approximately the average of the minimum noise levels. The L90 level is often referred to as the “background” noise level and is commonly used as a basis for determining noise criteria for assessment purposes

• Sound Power Level (LW) - this is a measure of the total power radiated by a source. The Sound Power of a source is a fundamental property of the source and is independent of the surrounding environment

• Sound Pressure Level (LP) - the level of sound pressure; as measured at a distance by a standard sound level meter with a microphone. This differs from LW in that this is the received sound as opposed to the sound ‘intensity’ at the source


A6

• Background noise – the underlying level of noise present in the ambient noise, excluding the noise source under investigation, when extraneous noise is removed. This is described using the LA90 descriptor

• Ambient noise – the all-encompassing noise associated within a given environment. It is the composite of sounds from many sources, both near and far

• Cognitive noise – noise in which the source is recognised as being annoying

• Masking – the phenomenon of one sound interfering with the perception of another sound. For example, the interference of traffic noise with use of a public telephone on a busy street.

Industrial Noise Policy Terminology

• Assessment Background Level (ABL) - is defined in the INP as a single figure background level representing each assessment period (day, evening and night). Its determination is by the tenth percentile method (of the measured LA90 statistical noise levels) described in Appendix B on the INP

• Rating Background Level (RBL) - is defined in the INP as the overall single figure background level representing each assessment period (day, evening and night) over the whole monitoring period (as opposed to over each 24hr period used for the ABL). This is the level used for assessment purposes. It is defined as the median value of:

• all the day assessment background levels over the monitoring period for the day;

• all the evening assessment background levels over the monitoring period for the evening; or

• all the night assessment background levels over the monitoring period for the night.

• Extraneous noise – noise resulting from activities that are not typical of the area. Atypical INP activities may include construction, and traffic generated by holiday periods and by special events such as concerts or sporting events. Normal daily traffic is not considered to be extraneous

• Most affected location(s) – locations that experience (or will experience) the greatest noise impact from the noise source under consideration. In determining these locations, one needs to consider existing background levels, exact noise source location(s), distance from source (or proposed source) to receiver, and any shielding between source and receiver


A7

• Noise criteria – the general set of non-mandatory noise level targets for protecting against intrusive noise (for example, background noise plus 5 dB) and loss of amenity (for example, noise levels for various land uses)

• Noise limits – enforceable noise levels that appear in conditions on consents and licences. The noise limits are based on achievable noise levels which the proponent has predicted can be met during the environmental assessment. Exceedance of the noise limits can result in the requirement for either the development of noise management plans or legal action

• Project Specific Noise Levels – target noise levels for a particular noise generating facility. They are based on the most stringent of the intrusive criteria or amenity criteria. Which of the two criteria is the most stringent is determined by measuring the level and nature of existing noise in the area surrounding the actual or propose noise generating facility

• Compliance – the process of checking that source noise levels meet with the noise limits in a statutory context

• Non-compliance – development is deemed to be in non-compliance with its noise consent/ licence conditions if the monitored noise levels exceed its statutory noise limit by more than 2 dB

• Feasible and Reasonable measures – feasibility relates to engineering considerations and what is practical to build; reasonableness relates to the application of judgement in arriving at a decision, taking into account the following factors:

• noise mitigation benefits (amount of noise reduction provided, number of people protected);

• cost of mitigation (cost of mitigation versus benefit provided);

• community views (aesthetic impacts and community wishes); and

• noise levels for affected land uses (existing and future levels, and changes in noise levels).

• Meteorological Conditions – wind and temperature inversion conditions

• Temperature Inversion – an atmospheric condition in which temperature increases with height above the ground

• Adverse Weather – weather effects that enhance noise (that is, wind and temperature inversions) that occur at a site for a significant period of time (that is, wind occurring more than 30% of the time in any assessment period in any season and/or temperature inversions occurring more than 30% of the nights in winter).

A.2 VIBRATION - GLOSSARY OF TERMS, DEFINITIONS AND METHODOLOGY

A.2.1 How to Measure and Control Vibration

Vibration refers to the oscillating movement of any object. In relation to construction projects, ground-borne vibration is the most likely outcome of works and potentially has three (3) effects on vibration sensitive receivers, these are:

• ground-borne vibration that may cause annoyance

• ground-borne vibration that may have adverse effect on a structure e.g. a building

• regenerated noise due to ground-borne vibration.

Each of these potential effects can be assessed in accordance with the relevant standard. Perceptible levels of vibration often create concern for the surrounding community at levels well below structural damage guideline values; this issue needs to be managed as part of the vibration monitoring program.

Vibration is typically measured using specific devices that record the velocity or acceleration at a designated receiver location – usually being the closest premises to works. Modern vibration monitoring devices will typically capture amplitude data for the three (3) orthogonal axes being, the transverse, longitudinal and vertical and also the frequency at which the measured vibration event occurs. Monitoring of this level of detail enables analysis of significant vibration events to determine compliance with relevant guidelines such as the NSW Department of Environment, Climate Change and Water - Vibration: A Technical Guideline and German Standard DIN4150 Structural vibration - Part 3: effects of vibration on structures.

Vibration propagates in a different manner to noise and can be difficult to control depending on the frequency of the source in question, although identifying the strategy best suited to controlling vibration follows a similar approach to that of noise. This includes elimination, control at the source, control along the propagation path and control at the receiver and/or a combination of these, such as no work/respite periods.

A.2.2 Vibration Descriptors

The following terms are often used to describe measured vibration levels.

• Parameter – an attribute with a value - for example, weighting;

• Particle Velocity – the instantaneous value of the distance travelled by a particle per unit time in a medium that is displaced from its equilibrium state by the passage of a sound or vibration wave;


A9

• Peak Component Particle Velocity (PCPV) – is the highest (maximum or peak) particle velocity which is recorded during a particular vibration event over the three (3) axes. PCPV is measured in the unit, mm/s;

• Phase – the relative position of a sound wave to some reference point, the phase of a wave is given in radians, degrees, or fractions of a wavelength;

• Acceleration – the change in velocity over time. Acceleration is dependent on the velocity and the frequency of the vibration event (velocity is a vector), as such acceleration changes in two ways - magnitude and/or direction. Acceleration is measured in the unit; m/s2;

• Perceptible – vibration levels that a receiver of building occupant may ‘feel’. 0.2mm/s is typically considered to be the human threshold for perception of vibration;

• Geophone or accelerometer – the transducer/device typically used to measure vibration;

• Damage – is defined in DIN 4150-3 (1999-02) Structural vibration - Effects of vibration on structures to include minor non-structural effects such as cosmetic damage or superficial cracking in paint or cement render, the enlargement of cracks already present, and the separation of partitions or intermediate walls from load bearing walls;

• Vibration Dose Value (VDV) – a concept outlined in Vibration: A Technical Guideline by the NSW Department of Environment and Climate Change & Water, which is a calculative approach to assessing the impact of intermittent vibration or extended periods of impulsive vibration. VDV require the measurement of the overall weighted RMS (Root Mean Square) acceleration levels over the frequency range 1Hz to 80Hz. To calculate VDV the following formula (refer section 2.4.1 of “the guideline”) is used:

25.0

0

4 )(

= ∫

T

dttaVDV

Where VDV is the vibration dose value in m/s1.75, a (t) is the frequency-weighted RMS of acceleration in m/s2 and T is the total period of the day (in seconds) during which vibration may occur;

• MIC - Maximum Instantaneous Charge or explosive charge mass (kg) detonated per delay (any 8ms interval); and

SD (m) - The scaled distance for air-blast and ground vibration from the charge to the receiver.
