1.0 Introduction

The Port of Melbourne is Australias largest container and general cargo port and is managed by the Port of

Melbourne Corporation (PoMC).

The Port of Melbourne is critical to Victoria's continued economic growth and development. Port of Melbourne

handles approximately 36% of Australias container trade, and is growing at record levels and is well above pre-

Global Financial Crisis volumes. With a compound growth rate of around 6% p.a., without additional capacity

within 4 to 5 years, the Port will reach its capacity.

The Port Capacity Project will reconfigure and redevelop Webb Dock returning it to its original role as an

international container handling facility. This new container handling terminal will be capable of handling the

equivalent of at least one million containers per annum. The Port Capacity Project includes the upgrade of

Melbournes largest container port, and will include the following:

- Reconfiguration of Webb Dock as a container handling facility, which will include landscaping, screening

(noise walls), dock deepening (dredging) and container storage areas.

- Internal road configuration to improve linkages between the docks, and to redirect port traffic away from

residential areas.

- Provision of additional vehicle delivery facilities for vehicle exports and imports, including pre-delivery

inspection facilities.

- Works to parkland areas to maintain buffers between the port and public areas.

Noise is a key issue for the Port Capacity Project. The project area is bound closely on the east side with

residential area, and there are residential areas located to the west and southwest.

The Port of Melbourne Corporation is committed to effectively managing the noise impacts associated with the

redevelopment of Webb Dock. As part of this commitment, AECOM has been engaged to develop an

Environmental Noise Assessment of the operation of the redevelopment of Webb Dock (Port Capacity Project).

2.0 Project Details

2.1 Schedule

The project construction is scheduled to commence in 2013, and conclude in 2017. It is anticipated that

operations would commence in 2016.

The Project is anticipated to continuously operate 24 hours per day, although operations are expected to peakduring the Day period, and generally operate at a reduced capacity during the Night period.

2.2 Site Layout

Webb Dock East is to comprise a new international container terminal. The operation of this area will include

container movement on and off transport ships, movement and stacking of containers, and truck loading and

unloading.

A new container storage area is proposed for the area of land north of Webb Dock East. The operation of this

area will include truck loading and unloading.Automotive trade is proposed to be relocated from its current location on Webb Dock East to Webb Dock West.

The operation of this area will include car transport on and off transport ships, and will also serve as a car storage

area.

Figure 1, the Webb Dock Precinct Concept Plan, shows the proposed layout of the Port Capacity Project.

2.3 Sensi tive Receivers

Residential noise sensitive receivers are located to the east, west, and southwest of the site in Port Melbourne,

Newport and Spotswood, and Williamstown respectively. The nearest residential area is located in Port

Melbourne, approximately 30 metres east of the site.

2.4 Noise Barriers

2.4.1 Exist ing Noise Barriers

A two-metre high noise barrier is currently installed along the west boundary of Perce White reserve, between the

walking trail and the existing terminal boundary. An approximately twometre high embankment is located along

the east of Webb Dock between the Webb Dock trail and Webb Dock. These features are shown in Figure 3 and

are required to be retained to control noise from the Project. It is understood that the 2-metre barrier will be

demolished as part of the Project, and reinstated prior to commencing operations..

2.4.2 Proposed Noise BarriersProposed noise barriers have been confirmed for the site along the east of the site, to the west of Todd Road. The

height, length and position of these noise barriers have been nominated based on preliminary acoustic design

work.

The noise barriers will be constructed from either Corten Steel or concrete panels. The noise barriers that are

constructed from Corten Steel must comprise a thickness of over 3mm.

When installed, the noise barriers should have no gaps or openings.

Figure 3 shows the proposed noise barrier heights and locations for the barrier along Todd Road. It is noted that

the gap between the barriers at the Todd Road and Williamstown Road intersection is required to be maintainedto provide access for emergency vehicles and pedestrians.

These barriers are required to ameliorate noise propagation toward the nearby residential area, and have been

included in all acoustic modelling in Section 7.0.

3.0 Environmental Noise Emission Criteria

The following sections outline the noise criteria that have been used as a basis for this Report. The noise criteria

are based on the requirements of State Environment Protection Policy (Control of Noise from Commerce, Industry

and Trade) No. N-1 (SEPP N-1). The noise criteria were provided to AECOM by Port of Melbourne Corporation

for this assessment.

3.1 State Environment Protection Policy No. N-1 (SEPP N-1)

SEPP N-1 prescribes procedures for determining the statutory environmental noise limits which apply at noisesensitive locations, such as residential areas, with respect to noise due to commercial, industrial and trade

operations. The noise limits prescribed by SEPP N-1 apply to the area of land on the noise sensitive property,

which is within 10m of the noise sensitive building.

The SEPP N-1 noise limits are dependent on:

- Zoning Levels, based on the planning scheme zoning types within 70m and 200m radii of the noise sensitive

area.

- The time of day i.e. different limits apply at different times of the day.

- The background noise level (LA90) in the noise sensitive area, in the absence of noise due to commercial,industrial or trade operations.

Under SEPP N-1, noise from the source under consideration is measured so as to determine its impact over a

continuous 30-minute period. Adjustments to the measured noise level are applied to account for the effects of

duration, tonality, intermittency and impulsiveness.

Note that SEPP N-1 does not apply to noise from audible emergency or safety alarms such as the reversing

alarms that are typically located on industrial equipment. Although not strictly assessed under SEPP N-1, noise

from these sources has been discussed as part of this assessment and recommendations have been provided for

controlling noise emission from these sources.

3.3 SEPP N-1 Noise Limits

SEPP N-1 noise limits have been determined by Resonate Acoustics and provided to AECOM by Port of

Melbourne Corporation. AECOM were directed by Port of Melbourne Corporation to use the noise limits

determined by Resonate Acoustics for this assessment. AECOM were not commissioned to undertake a peer

review of noise limit determination.

The full report showing background noise monitoring locations and results, zoning level calculation, and resultant

noise limits is shown in Appendix 1. The Table below shows the measurement results, calculated Zoning Levels,

and the SEPP N-1 noise limits that were presented in the Resonate Acoustics report.

4.0 Current Operations

Currently, the site at Webb Dock East is occupied by Patrick Stevedores, Toll and Sea Road. The current

operation of this area includes automotive storage and importing facilities, which includes car transport on and off

ships.

4.1 Noise Sources

It was determined during a site visit to the areas surrounding Webb Dock, and through discussions with PoMC,

that the current main noise sources at Webb Dock include ship idling noise and car movement noise. However,the noise emissions from these sources were observed to be insignificant in terms of impacts to nearby noise

sensitive areas.

4.2 Noise Levels at Residences

During a site visit to the current Webb Dock it was confirmed that noise emissions from the current Webb Dock

East operations were not audible at Perce White Reserve, adjacent to the Dock.

Therefore, the noise levels due to current operations were not measureable and are deemed compliant with the

SEPP N-1 noise l imits at the nearest residences.

Truck movements along Todd Road were clearly audible, however, are not assessed under SEPP N-1, as traffic

on public roads is not assessable under SEPP N-1. Note that the truck movements within the proposed facility are

assessed as part of this study.

5.0 Acoustic Modelling Methodology

This section outlines the methodology that was used to undertake acoustic computer modelling and predict the

SEPP N-1 Effective Noise Levels due to the proposed Port Capacity Project. This section details the modelling

software that was used, lists the assumptions and parameters used in the modelling, and lists the Sound Power

Levels used for each noise source.

5.1 Noise Modelling Software

SEPP N-1 Effective Noise Levels due to the proposed operations were predicted using SoundPLANenvironmental noise modelling software, version 7.0. This software is capable of accurately predicting

environmental noise levels and mapping the results. SoundPLAN is used extensively worldwide, and takes a

standards-based approach to modelling.

The modelling was undertaken using the CONCAWE1 prediction method that is widely used in Australia for

predicting industrial noise, and accepted by EPA.

The CONCAWE method was originally developed for predicting the long-distance propagation of noise from

petrochemical complexes. It is especially suited to predicting noise propagation over large distances because it

accounts for a range of atmospheric conditions that can significantly influence the propagation of noise over large

distances.

5.2 Noise Modelling Parameters

The following sections outline the parameters that were put into the acoustic model to predict the noise levels at

the nearest noise-sensitive locations.

5.2.1 Site Features

Locations of features that were included in the acoustic model were determined from aerial photographs of the

area, Project Layout (GHD Drawing 31-25563 Revision B Dated 30 October 2012), and discussions with GHD

propagation of noise. Likewise, a light to moderate wind (i.e. 1 to 3 m/s) from the source to the receiver tends toassist the propagation of noise to the receiver, while the impact of noise for any receivers in the opposite directionwould be reduced. For higher wind speeds, the wind becomes too turbulent to effectively assist the propagation ofnoise, and background noise levels tend to increase, masking any increases in noise level due to wind-assistedpropagation.

Noise levels were predicted at the noise sensitive receptors based on neutral atmospheric conditions with 3 m/s

wind in direction of receiver, as this is the worst-case scenario in terms of noise propagation in this instance.

Other weather parameters were based on typical worst-case weather conditions, based on climate averages for

Melbourne taken from the Bureau of Meteorology, and were modelled as follows:

- Air pressure: 1013.25 mbar

- Relative. Humidity: 70 %

- Temperature: 10 C

- Pasquil Stability Class: D

- Wind speed: 3 m/s

- Wind direction: worst case (source to receiver)

In general, the meteorological conditions in the vicinity of Webb Dock include higher wind speeds than were

modelled. As noted above, wind speeds in excess of 3 m/s are not favourable for noise propagation due to

turbulence, and cause increased background noise levels at the receiver locations. Therefore, wind speeds of

greater than 3 m/s were not incorporated into the acoustic model.

5.2.3 Noise Source Sound Power Levels

Table 3 presents the Sound Power Levels used in the acoustic model, prior to the application of any applicable

SEPP N-1 adjustments, such as for duration.

8.0 Reversing Alarms

Audible warning alarms are not assessed under SEPP N-1. Tonal audible warning alarms, however, are often

found to cause considerable annoyance to nearby, and even more distant receivers due to the tonal and intrusive

nature of the noise that they emit.

A tonal alarm is generally more audible over greater distances than a broadband-type noise, which tends to be

masked by background noise levels more easily, and is less discernible.It is therefore recommended that consideration is given to eliminating the use of all tonal audible warning alarms

by the future international container terminal and empty container park operator..

Other options for movement alarms include implementing a spotter, visual alarms such as flashing lights, and

broadband audible alarms. Advancements have been made in in audible warning alarms, such that there are

alarms that adjust the sound output to be above the background, and alarms that focus the sound in the area

where persons may be potentially at risk, rather than emitting noise in al l directions equally.

Broadband alarms have been demonstrated to reduce noise complaints from the surrounding community on

construction sites. This is due to the broadband nature of the sound being emitted, which is masked more easily

by other background noises. Some of these alarms are also designed such that the sound is directed to the area

of risk, such that the noise emission is directed toward a residential area for a shorter period of time.

Therefore, where audible warning alarms are required on site at the future international container terminal and

empty container park, it is recommended that broadband-type audible warning alarms are implemented.

Broadband alarms, when selected appropriately, will minimise noise impact on the surrounding community but will

not reduce on-site personnel safety.

10.0 Summary

AECOM has been engaged by GHD and Port of Melbourne Corporation to conduct an acoustic assessment of the

proposed operation of the Port Capacity Project at Webb Dock.

This assessment includes investigation of the proposed port operations, and the predicted noise emissions to the

nearby noise-sensitive areas. The predicted noise emissions have been assessed in accordance with the

Victorian EPA SEPP N-1 Policy. The assessment is concentrated on predicting for compliance in relation to the

more stringent of the three SEPP N-1 noise limits, namely the Night period noise criterion.

The modelled port operation Scenarios that were determined to be compliant with the SEPP N-1 Night periodcriteria are:

- Scenario 1b, which is the traditional manual facility, which includes container movements by manned

straddle cranes from port to truck, and container forklifts operating in the empty container park. New, quiet-

type straddle cranes and container forklifts, such as electric, battery operated, or hybrid equipment are

implemented in this scenario.

- Scenario 2, which is the fully-automated facility that comprises automated stacking cranes and automated

guided vehicles. All equipment in this scenario is assumed to be electrically powered.

Additional advice has been provided in relation to noise from trucks travelling through Westgate Park and inrelation to Audible Warning alarms.

1 IntroductionResonate Acoustics was commissioned by Port of Melbourne Corporation (PoMC) to conduct

background noise monitoring in the vicinity of Webb Dock as part of the Port Capacity Project

(PCP).

Based on the results of background noise monitoring, noise criteria have been established for

noise sensitive areas (i.e. residential) in accordance with the Victorian State Environmental

Protection Policy (Control of Noise from Commerce, Industry and Trade) No. N-1 (SEPP N-1).

The Victorian Environmental Protection Authority (EPA) provides guidelines in relation to the

management of noise from construction sites in the EPA Noise Control Guidelines Publication

1254 (October 2008). Based on the results of background noise monitoring, noise level

guidelines have been established for weekend and evening works in accordance with EPA

undertaken at this location to accurately determine background noise levels in this area. The

acoustic environment in the vicinity of the measurement location was dominated by road traffic

noise from the Westgate Freeway.

Site 2 - The Strand, Williamstown

Background noise monitoring was conducted at a residential premise on The Strand,

Williamstown to accurately determine background noise levels in the Williamstown area.

Background noise levels were not assessed in Newport, as the Newport Power Station may

have had a significant adverse affect on the measured background noise levels. This monitoring

site is located on the boundary of Williamstown and Newport and was not adversely affected by

noise from the Newport Power Station. The acoustic environment in the vicinity of the

measurement location was typically quiet with no significant noise sources in the near vicinity.

Analysis of the unattended noise monitoring results and the Bureau of Meteorologys 30 minute

interval weather data for Melbourne (the nearest weather station to the unattended monitoring

locations) indicated that adverse weather existed during limited periods of the measurement

period. As such, measured data during the periods outlined in Table 5 have been excluded from

this assessment. Adverse weather is defined as periods with high wind or significant rainfall.

have had a significant adverse affect on the measured background noise levels. Background

noise monitoring data from The Strand, Williamstown was used in order to determine SEPP N-1

noise limits for Newport. This monitoring site is located on the boundary of Williamstown and

Newport and was not adversely affected by noise from the Newport Power Station.

6 SummaryResonate Acoustics was commissioned by Port of Melbourne Corporation to conduct

background noise monitoring in the vicinity of Webb Dock as part of the Port Capacity Project.

Based on the results of background noise monitoring noise limits have been established fornoise sensitive areas (i.e. residential) in accordance with the Victorian State Environmental

Protection Policy (Control of Noise from Commerce, Industry and Trade) No. N-1 (SEPP N-1).

Established noise limits are applicable to operations and dredging works associated with the

PCP. The specified noise limits are:
