Noise and Vibration CEMP Sub-plan Advisian 2 of 42

Synopsis

The Noise and Vibration Construction Environmental Management Plan (CEMP) Sub-plan has been

prepared by Advisian to identify environmental risks associated with noise and vibration and how

those identified risks will be managed and mitigated for Stage 2 construction activities for the Eden

Breakwater Wharf Extension herein referred to as Stage 2 of “the Project”. The Project is to be

carried out by NSW Department of Industry (the Principal).

Specifically, the Noise and Vibration CEMP Sub-plan has been prepared to address the

requirements of Conditions C3b and C4 of the Infrastructure Approval (SSI 7734) and details how

the performance outcomes, commitments and mitigation measures specified in the Environmental

Impact Statement (EIS) and Response to Submissions (RTS) Report prepared during the planning

approval stage of the Project, as well as the relevant terms of the Infrastructure Approval, will be

implemented and achieved during construction. In accordance with Condition C17, the

requirements of the Noise Construction Monitoring Program in Condition C10a, C11, C12 and C13

have been incorporated into this Sub-plan.

1 Introduction

1.1 Purpose and Objectives of the Sub-plan

Advisian has prepared a Construction Environmental Management Plan (CEMP) to identify the

environmental risks and detail how those identified risks will be managed and mitigated for all

construction activities for the Eden Breakwater Wharf Extension herein referred to as “the Project”.

The CEMP also addresses the relevant requirements of the Infrastructure Approval and other

applicable approvals and permits.

This Noise and Vibration CEMP Sub-plan has been prepared by Advisian to address the

requirements of Conditions C3b and C4 of the Infrastructure Approval (State Significant

Infrastructure (SSI) Approval No 7734) and detail how the performance outcomes, commitments

and mitigation measures specified in the Environmental Impact Statement (EIS) and Response to

Submissions (RTS) Report prepared during the planning approval stage of the Project, as well as

the relevant conditions of the Infrastructure Approval, will be implemented and achieved during

construction. Further, in accordance with Condition C17, the requirements of the Noise

Construction Monitoring Program in Conditions C10a, C11, C12 and C13 have been incorporated

into this Sub-plan.

Construction of the Project will be delivered in two stages under two separate contracts by a

Dredging Contractor (Stage 1) and a Marine Structures Contractor (Stage 2). The two Contractor’s

activities on-site will occur in series: that is, there will be only one Contractor on-site at any one

time. A description of the Project, including staged construction is provided in Section 1.3. This

Noise and Vibration CEMP Sub-plan applies to Stage 2 of construction and forms part of the CEMP

for the Project.

This Noise and Vibration CEMP Sub-plan has been prepared in consultation with the Bega Valley

Shire Council (BVSC), NSW Environment Protection Authority (EPA) and the Project’s Community

Consultative Committee (CCC). The details of the consultation undertaken are set out in Section 2

with copies of written correspondence between the Principal and the agencies and stakeholders

provided in Appendix A.

The objectives of this Noise and Vibration CEMP Sub-plan are to:

Ensure all Contractor(s) and Project personnel clearly understand their environmental

obligations under the relevant Project approvals, permits and licences in relation to noise and

vibration;

Enable the Project to comply with the relevant Commonwealth and State Government

requirements and all relevant Australian standards;

Describe the management/mitigation measures and requirements as detailed in the CEMP, EIS

(and as amended by the RTS Report) and all other approvals, permits and licences to ensure

noise and vibration risks are minimised to As Low As Reasonably Practicable (ALARP); and


Detail the required Noise Monitoring Program required during construction activities relating

to Stage 2.

This Noise and Vibration CEMP Sub-plan and appended Noise Monitoring Program, have been

developed in consideration of the following relevant guidelines:

NSW Interim Construction Noise Guideline; and

Assessing Vibration: A Technical Guideline (DECC 2006).

1.3 Project Description

The Project comprises the extension of the existing Eden Breakwater Wharf and dredging of the

approach channel and berth pocket with offshore disposal, to accommodate the berthing of cruise

ships of up to 325m in length.

Key features of the Project include:

Extension of the existing wharf by approximately 95m;

Installation of three mooring dolphins and two berthing dolphins;

Installation of new landside bollards to restrain the ship’s bow;

Dredging of approximately 231,500m3 of in-situ material (including over-dredging allowance);

Transport and placement of the dredge material at an offshore disposal site;

Installation of minor services (lighting, power, potable water and emergency water); and

Installation of navigational aids.

The Eden Breakwater Wharf is located in Snug Cove, Eden, New South Wales and the offshore

disposal site is approximately 6 nautical miles offshore from Twofold Bay.

As described above, construction of the Project will be delivered in two stages (as described in the

Staging Report, Revision 0, 24 July 2017 for more detail) with only Stage 2 construction activities

the subject of this Noise and Vibration CEMP Sub-plan.

Key Stage 2 construction activities potentially leading to adverse noise and vibration impacts relate

to piling activities.

Piling to construct the new wharf deck will constitute 78 steel piles, which will be driven to a design

toe level (level into the seabed) by a piling hammer lifted by a crane mounted either on a barge or

from the existing wharf. Prefabricated headstocks will then be installed by crane onto the piles.

Rock anchors may be installed in some piles, depending on pile refusal level. Three to four piles will


support each of the headstocks (or bents). Prefabricated concrete deck panels will then be lifted

into place, spanning across two adjacent headstocks (or bents). Once all deck panels have been

installed, gaps will be filled with a gap filler product, before an in-situ concrete topping slab is

installed and minor services are fitted to the deck.

Three mooring dolphins and two berthing dolphins will also be installed along the fender line

(berthing face). Each dolphin will consist of six steel tubular piles driven into the seabed by a piling

hammer suspended from a crane mounted on a barge. Once the piles are established, the pre-

fabricated dolphin modules will be installed with bollards on each of the decks, access platform,

safety ladders and hand railings fitted. Panel fenders will be installed on the berthing dolphins.

Onshore, three bollards will be installed, consisting of six piles per bollard. Finally, the navigational

tower will also require a single pile.

A total of 127 piles will be required and it is anticipated that piling will occur over approximately six

months.

During the installation of the piles, a vibro-hammer will be utilised at commencement of driving in

some areas. These piles will be installed to maximum achievable depth with the vibro hammer,

prior to use of the hydraulic hammer to complete the install. Due to the required pile loads, and

the expected geotechnical conditions, as well as the requirement for load testing, all piles will

require driving with a hydraulic hammer; however the extent of this will be minimized through the

use of the vibro-hammer. This approach will not be possible for all piles, due to the presence of

rock from bed level in some areas, however, this approach will be adopted wherever possible.

The key reference documents for a detailed description of the existing noise and vibration

environment are Section 9.6 of the EIS (Advisian 2016), Appendix K of the EIS – Noise, Vibration

and Air Quality Assessment and Addendum Report (PEL 2016a and PEL 2016b).

Further detail relating to the construction activities for the Project is contained within the CEMP

prepared under Conditions C1 and C2 of the Infrastructure Approval.


2 Stakeholder Consultation

BVSC, the EPA and the CCC (the then Community Liaison Group) were consulted during the

preparation of the EIS, CEMP and RTS for the Project and provided feedback during DP&E’s

assessment of the Project.

The Infrastructure Approval Part C - Construction Environmental Management, requires

preparation of a CEMP and a number of CEMP Sub-plans and Construction Monitoring Programs

to be prepared in consultation with relevant government agencies.

As required by Conditions C3 consultation regarding this Noise and Vibration CEMP Sub-plan was

undertaken by the Principal (and Contractor as relevant) with the BVSC, the EPA and CCC. As

required by C12, consultation regarding the Construction Noise Monitoring Program was

undertaken by the Principal with BVSC and the EPA. Their requests and the Principal’s response are

outlined in Table 2-1.

Table 2-1 Noise and Vibration Sub-plan Agency requests and Principal’s response

Agency Request Response

BVSC No requests received. N/A

NSW EPA Recommendation to consider a

formalised ongoing review process

of all employed noise and vibration

management and mitigation

practices throughout Stage 2, to

ensure changes in construction

activities continue to meet best

management practice and

appropriately consider impacts on

noise to sensitive receivers.

The Project has developed and

implemented a Construction

Compliance Monitoring Program, in

which regular (weekly) formal checks

are completed against commitments

and management measures. Further,

continuous noise monitoring during

piling, the implemented community

communications strategy, and the

dedicated Project Communications

Advisor will ensure that impacts to

noise sensitive receivers can be

managed effectively throughout the

Project.

CCC A member of the committee

explained that many businesses of

the Port Precinct close by 3pm, and

requested if the construction

program could be modified to

consider this.

The daily program cannot be altered

everyday to pile only after 3pm due

to the many other aspects

influencing when piling will be

scheduled that day, as it has the

potential to significantly draw out

the overall program. However, the

Contractor can commit to

accommodating businesses as much

as possible, whilst still adhering to


Agency Request Response

the overall Project program.

Copies of all written correspondence and minutes of the CCC Meeting in which the Noise and

Vibration CEMP Sub-plan was discussed, are contained in Appendix A.


3 Noise and Vibration Management

3.1 Permitted Hours of Work

In accordance with Condition E9 of the Infrastructure Approval, Construction must only be

undertaken during the following standard construction hours:

a. 7:00am to 6:00pm Mondays to Fridays, inclusive; b. 8:00am to 1:00pm Saturdays; and c. At no time on Sundays or public holidays.

Except in the following circumstances:

i. For the delivery of materials required by the NSW Police Force or other authority for

safety reasons;

ii. Where it is required in an emergency to avoid injury or the loss of life, to avoid

damage or loss of property or to prevent environmental harm; and

iii. Where different construction hours are permitted or required under an EPL in force in

respect of the Construction, in which case those construction hours must be complied

with (not relevant for this Stage of work).

3.2 Traffic Noise

A road traffic assessment completed by PEL (PEL 2016a) did not identify any exceedances of

guideline noise levels due to the increase to existing traffic noise levels for day time construction

hours. Due to the above described permitted work hours, little to no construction traffic will occur

in evening and night time hours.

All regular suppliers (such as concrete truck drivers) will be required to undergo a Project-specific

truck induction to familiarise themselves with the Project’s requirements such as approved

transport routes and noise mitigation outlined in this Noise and Vibration CEMP Sub-plan.

Irregular delivery drivers will be forwarded a copy of the approved transport routes and permitted

delivery times along with their contract/purchase order.

3.3 Underwater Noise Assessment

Underwater piling noise is characterised based on the size of the pile and piling method utilised.

Table 3-1 summarises the characteristics of piling noise (PEL 2016a).


Table 3-1 Impact Piling Noise Characteristics (source: PEL 2016a)

PEL undertook an underwater construction noise impact assessment (PEL 2016a), which describes

the predicted underwater noise measurements, based on measurements undertaken as part of the

construction of the Naval Wharf at the Port (McCauley et al 2002). The piling methods for this

Project are considered similar to the work conducted at the Naval Wharf and therefore PEL

predicted underwater noise levels would be similar. These are shown in the below table.

Table 3-2 Impact Piling Underwater Noise Predictions (Source: PEL 2016a)

3.3.1 Underwater Noise Monitoring

Marine species’ responses to underwater noise include changes in vocalisation, resting, diving and

breathing patterns, changes in mother-infant spatial relationships and avoidance of the noise

source (PEL 2016a). The framework for management and mitigation of underwater noise impact

from piling activities includes observation zones, shut-down zones and soft-starts. These

procedures are outlined in the Project’s Aquatic Ecology CEMP Sub-plan (Revision 1, 9 August

2017).

Monitoring of underwater noise is not required for the Project. In the event that underwater noise

impacts from piling are shown to be impacting marine species, the Monitoring Improvement

Procedure outlined in the Project’s Aquatic Ecology CEMP Sub-plan (Revision 1, 9 August 2017) is

to be followed.

3.4 Above-water Noise Assessment

An assessment of the predicted above-water noise levels associated with piling activities, and the

noise monitoring that will be conducted is described in detail in the Construction Noise Monitoring

Program, which is detailed in Section 5 of this Noise and Vibration CEMP Sub-plan.

3.5 Above-water Vibration

A Construction Vibration Assessment conducted by PEL (2016a) predicted vibration levels of plant

at a range of distances. Table 3-3 presents a summary of these predicted levels, based on 200kNm

hammer operating at full capacity.


Table 3-3 Predicted Vibration Levels (Source: PEL 2016a)

These results indicate that vibration levels at the nearest potentially impacted hillsides, adjacent to

wharf, could potentially reach 2-3mm/s during piling at refusal. However, typical vibration levels of

less than 1mm/s are expected, though vibration testing will confirm the predicted levels (refer to

Section 3.5.3).

3.5.1 Human Comfort

When vibration comprises repeated events, each of a similar value and duration, a Vibration Dose

Value (VDV) may be calculated. Acceptable values for impulsive vibration in the range of 1-80Hz

are provided in the Assessing Vibration a Technical Guideline (DECC 2006). These are shown in

Table 3-4, of which only the daytime values are of relevance to Stage 2 of the Project.

Table 3-4 Acceptable Vibration Dose Values for Intermittent Vibration (m/s1.75

) (Source: PEL

2016a, as derived from EPA 2006)

Predicted VDV’s were calculated by PEL (2016a) and compared with the Guidelines (EPA 2006), for

the nearest sensitive receiver (located 250m from the Project). The results are provided in Table 3-5

and will be confirmed following vibration testing (refer to Section 3.5.3).


Table 3-5 Predicted Vibration Dose Levels (Source: PEL 2016a)

3.5.2 Building Damage

Given the absence of an Australian Standard, PEL (2016a) conducted a Vibration Assessment on

Building Damage based on the German Standard (DIN 4150-3-1999 Structural Vibration – Part 3

Effects of vibration on structures). The recommended limits from DIN4150 are shown above in Table

3-3 and compared to the predicted vibration levels of plant at a range of distances. The results of

these predictions show that vibration levels are not expected to cause any building damage. These

predictions will be confirmed following vibration testing (refer to Section 3.5.3).

3.5.3 Vibration Testing

Vibration testing was a recommendation of the PEL (2016a) report given predicted vibration levels

were highly conservative and could vary significantly with site-specific ground conditions.

Therefore, a Senior Acoustic Engineer from PEL will undertake vibration testing at the

commencement of piling to confirm the predicted vibration levels described.

Testing will include measurements at decreasing distances from the nearest sensitive receivers

toward the piling activities to estimate site-specific vibration propagation. Testing will occur over a

two-week period at the commencement of piling.

Testing will involve the following steps:

Measurements using a vibration monitor with triaxial accelerometer;

The accelerometer coupled to the ground/structures with consideration to AS2775 Mechanical

vibration and shock – Mechanical mounting of accelerometers;

Determination of vibration dose values and peak particle velocities in accordance with

Assessing Vibration: A Technical Guideline (DEC 2006); and

Reporting, including date, time and location of monitoring, the name of the person

conducting the monitoring, the peak particle velocity and vibration dose value.

Following completion of the testing a report summarising the findings compared to the relevant

guideline vibration levels will be completed.


4 Management Control Measures

An Environmental Risk Analysis was undertaken during the preparation of the EIS to identify

potential environmental impacts associated with the construction (and operation) of the Project.

The Environmental Risk Analysis also considered the proposed mitigation and management

measures for the Project and residual risks following their implementation. Noise and vibration was

one of the four key environmental risks identified in the Environmental Risk Analysis (Advisian

2016).

As part of the Project requirements (as described in Section 5 of the CEMP), an Environmental Risk

Assessment (ERA) has been developed in relation to Stage 2 construction activities to form part of

the Project Risk Assessment. The CEMP contains this ERA and identifies key environmental risks

applicable to Stage 2 construction activities and management controls to ensure that any risks are

managed to ALARP. The ERA identifies noise and vibration and associated risks as low-medium.

The Contractor will implement reasonable and practicable measures to avoid or minimise impacts

to the environment and community that may arise from the Project. The Contractor will ensure that

work is performed in a way that minimises impacts on the natural environment and complies with

the CEMP and related procedures, relevant legislation, regulations and rules, licences, approvals

and Project commitments made by the Principal.

In line with Condition E10 of the Infrastructure Approval, respite periods will be provided given

noise is expected to exceed the Highly Affected Noise level of 75dBLAeq, 15 minute during piling

activities. The timing of respite was discussed in consultation with the CCC, and the following

arrangements have been agreed during piling activities:

Planned respite from pile driving for a 1 hour duration during the period of 12:00pm and

2:00pm; and

Non-scheduled respite during natural breaks in construction activities, such as while resetting

for piles.

Specific control measures required to manage environmental impacts during the construction

works are described in the CEMP and must be complied with by all Contractor(s), as relevant to

5 Noise Construction Monitoring Program

This section forms the Noise Construction Monitoring Program required by Condition C10a and in

accordance with Condition C17 of the Infrastructure Approval.

The Monitoring Program has been prepared in consultation with BVSC and EPA. The details of the

consultation undertaken are set out in Section 2 with copies of written correspondence between

the Principal and the agencies provided in Appendix A.

5.1 Baseline Data

Baseline noise monitoring was conducted by acoustic specialists, Pacific Environment Limited (PEL)

between 10 December and 19 December 2015 (PEL 2016a). Monitoring was conducted at three

locations (Figure 5-1, Table 5-1); L1, L2 and L3. L1 was selected to be representative of the existing

traffic noise conditions as it is located just next to Albert Terrace; the only route that connects the

port with the rest of the town and inland. L2 and L3 are considered representative of the two Noise

Catchment Areas (NCA1 and NCA2).

Figure 5-1 Noise Catchment Areas and Noise Monitoring Locations (source: PEL 2016a).


Table 5-1 Noise Monitoring Locations, MGA Zone 55 (source: PEL 2016a)

The existing acoustic environment was characterised by a combination of long term (unattended)

(refer to Table 5-2) and short term (attended) (refer to Table 5-3) noise measurements.

Table 5-2 Short term (attended) Noise Measurement Results (source: PEL 2016a)


Table 5-3 Long term (unattended) Noise Monitoring Results (source: PEL 2016a)

Noise monitoring indicated a semi-rural environment, strongly influenced by intermittent noise

sources such as traffic and activities around the port (commercial and industrial) and that the

acoustic environment is slightly different depending on the Noise Catchment Area (PEL 2016a).

Full details of the baseline study are detailed in the Noise, Vibration and Air Quality Assessment

report prepared by PEL (PEL 2016a).

Further noise monitoring has been undertaken more recently during Stage 1 Construction

activities. It was concluded that the baseline noise environment was generally similar to the

monitoring results described in the PEL (2016a) Report.

No further baseline data is proposed to be collected in relation to noise for the Project.

5.2 Project Specific Noise Levels

Project-specific noise management levels were determined by PEL (2016a) using the baseline

results described in Section 5.1, a summary of which are provided in Table 5-4.

Table 5-4 Project Specific Construction Noise Management Levels, dB(A) (source: PEL 2016a)

5.3 Above-water Noise Assessment

A construction noise assessment was completed by Pacific Environment Limited (PEL) (2016a) for

the Project. Those relating to Stage 2 construction activities only will be discussed.


Stage 2 construction activities were modelled via two scenarios; piling (shown below as Scenario 3)

and wharf extension construction works (shown below as Scenario 4), both during daytime hours.

The indicative construction fleet for the modelling is shown in Table 5-5. Predicted construction

noise from piling and wharf construction works were determined for each of the identified

sensitive receivers (PEL 2016a) (refer to Figure 5-2 and Figure 5-3). Full predicted noise levels for

the relevant construction scenarios are available in PEL 2016a, with a summary shown below in

Table 5-8 and Table 5-9, noting that for impact piling within Scenario 3, a +5dB impulsivity penalty

was applied as per the Interim Construction Noise Guideline (ICNG) (DECC 2009). Relevant noise

levels have been presented with a magnitude of noise exceedance (refer to Table 5-8), with red

indicating the predicted noise level that exceeds the “Highly Noise Affected” (>75dB(A) criteria).

The below predicted noise levels (refer to Table 5-8 and Table 5-9) form the compliance levels for

Stage 2 construction activities.

Table 5-5 Indicative Construction Fleet for Noise modelling (source: PEL 2016a)

Noise sources were assessed during a 15 minute period, assuming the worst case scenario (running

continuously) with the exception of those shown in Table 5-6.

Scenario 4 relates to wharf extension construction works for nearby sensitive receptors (source: PEL

2016a).



Table 5-9 Predicted Construction Noise, where Scenario 3 relates to piling activities and

Scenario 4 relates to wharf extension construction works for extended receptors (source: PEL 2016a)

5.4 Above Water Noise Monitoring

As a result of the predicted noise levels and level of predicted exceedances above the Project-

specific noise management levels during piling (Scenario 3 described in Section 5.3), above-water

noise monitoring will be undertaken during piling activities.

Details of the Construction Noise Monitoring Program can be found in Appendix B, and is

summarised below.

Continuous noise monitoring shall be undertaken at two of the same (or close to, pending

resident-approval of the location) monitoring locations as the baseline and Stage 1 monitoring

locations (Figure 5-4) to verify noise levels during piling compared with the predicted noise levels

shown in Section 5.3. Where predicted noise levels are not being achieved, it will serve as

notification for the Project to review the implemented mitigation measures, or to temporarily halt

works and provide further respite.


Figure 5-4 Noise monitoring locations during piling works

Construction noise levels during piling will be monitored via a combination of attended (for the

first two weeks of piling) and unattended (throughout the duration of piling) noise measurements.

Sound level meters (Figure 5-5) will include 1/3 octave frequency data and/or audio capture to

allow acoustic engineers to filter extraneous data and target piling noise sources to assist in the

determination of piling noise contribution to the measured levels.


Figure 5-5 Example noise loggers to be used for noise monitoring

Monitoring will include:

Operator attended 15 minute measurements both during and outside piling activities at

locations representative of the nearest monitoring locations and sensitive receivers for the first

two weeks of pile driving works.

Unattended background noise measurements in consideration to AS1055.1. Monitoring will be

continuous over the period of piling. The noise loggers with telemetry reporting will upload

and save data every 15 minutes, to allow for remote viewing through a password protected

website.

Prevailing meteorological conditions over the monitoring period from the nearest Bureau of

Meteorology (BoM) automatic weather station(s).

All monitoring loggers will be calibrated by a NATA testing laboratory with infield checks of

instrument calibration. Calibration certificates shall be provided for record retention purposes.

5.4.1 Attended Monitoring

For the first two weeks of pile driving works, operator attended 15 minute measurements will be

undertaken both during and outside piling activities (during the daytime) at locations

representative of the nearest monitoring locations and sensitive receivers. The date, time and

location of monitoring will be recorded, in addition to the name of the person conducting the

monitoring and details of site activity, environmental noise characteristics and weather being

noted.


Statistical descriptors will be recorded for 15 minute intervals, including LAeq, LA10, and LA90 levels.

5.4.2 Un-attended Monitoring

Unattended continuous noise monitoring will occur throughout piling activities. With data logging

to be collected over 15 minute statistical intervals for LAmax, LA1, LA10, LAeq, and LA90 descriptors. Data

will be presented as daily noise logger graphs.

Remote data download will be available via mobile internet (statistical descriptors for the standard

monitoring intervals, eg LAeq, 15 minute) to facilitate review of unattended noise levels and compliance

limits, in addition to informing any noise related enquiries or complaints. This will enable Project

staff to verify noise levels within a shorter time period (within several hours of a complaint or

enquiry).

5.5 Reporting of Monitoring Results

A high-level summary of noise (and vibration) monitoring results will form part of the Contractor(s)

weekly report described in Section 7.2 of the CEMP, detailing any noise and vibration related

incidents and details of any noise and vibration management reviews.

Formal monthly noise monitoring reports will be prepared, including:

Monitoring methodology;

Monitoring results and observations;

Instrument set calibration certificates;

Graphical presentation of all unattended noise logging data; and

A summary of any recommended or additional noise mitigation measures implemented and

an evaluation of their effectiveness.

Further detail relating to noise monitoring and vibration measurements will be included in the

Contractor(s) Environmental Management Monthly Report to the Principal described in Section 7.4

of the CEMP.

5.6 Monitoring Improvement Procedure

Where predicted noise levels are not being achieved, it will serve as notification for the Project to

review the implemented mitigation measures and work practices, or to temporarily halt works and

provide further respite.

Reviews of the Noise Construction Monitoring Program will be undertaken as relevant, where

deficiencies, non-conformances or issues are identified as a result of Contractor(s) and Principal

environmental inspections and audits, or community complaints. Following the identification of an

alternative management measure(s) that are considered to improve noise and vibration impacts,

relevant procedures and plans will be updated, and submitted to the ER for consideration and

approval under Infrastructure Approval Condition A16(j).


6 Reporting

Routine reporting must be undertaken in accordance with the CEMP, including:

Minutes

MEETING Community Consultative Committee (CCC) - Eden Breakwater Wharf Extension Project

MEETING NO. 26 –Extraordinary General Meeting DATE Wednesday, 13 December 2017

LOCATION The Auditorium – Eden Fishermen’s Club

TIME 6.00pm

ATTENDEES Gail Ward, John Aveyard, Richard Lamacraft, Leanne Scott, Simon Wakefield, Mike Crandell, Mark Lomas, Greg Thomson, Glenn Vardy, Chantel Steele, Tony Matthews, Rob Davis, Tomas Rooney, Coral Reynolds

APOLOGIES Megan Cleary, Kell Dillion, Natalie Godward, Debbie Meers, Dr Denis Lawrence, Graham Stubbs, Rob Bain, Andrew Dooley

PREPARED BY Coral Reynolds

1. Acknowledgement to Country, welcome and apologies

Simon thanked attendees for coming to the meeting and acknowledged the traditional custodians and peoples of the Country, both land and sea, and paid his respects to Elders past and present. Simon also acknowledged meeting apologies.

2. Stage 2 overview

Mike provided an overview of Stage 2 works which included a discussion of the works to be undertaken as follows:

Dolphins – 30 piles

Wharf – 78 piles with approximately 23 rock sockets to be bored

Onshore bollards -15 piles with approximately15 rock sockets to be bored

Navigation Tower – 1 to 3 piles

Services installation

Line marking activities

Approved construction hours o Monday to Friday 7am to 6pm o Saturday 8am to 1pm o Sunday and Public Holidays – No Work o Additional rostered days off during the year.

Richard asked about the tug working and turbidity in the Port. Mike advised there were high spots on the seabed and that these high spots were being removed which has caused minor turbidity levels. Richard asked if the turbidity would be an issue for the Mussel Farm. Greg advised that the modelling that has been undertaken has shown that settling of the sediment would be relatively quick. It was discussed that a toxic algal bloom forced the temporary closure of the Mussel Farm prior to dredging commencing and the temporary closure is not related to dredging or any direction given to the mussel farm by the Department. The Mussel Farm has chosen to undertake maintenance on their vessels and harvest/grow out mussels from the Boydtown mussel farm during the dredging campaign. . Leanne suggested that additional communications should be prepared to communicate this to the community. John asked about the scour protection being laid and how to know if the mattresses were being laid in the right place. Mike advised there was a grid pattern being followed and that laying the mattresses was similar to paving. In addition, detailed hydrographic surveys were also being undertaken to ensure correct alignment, and that divers were under the water to guide the

Page 2 of 5

mattresses into place. Rob advised the hydrographic survey is being done weekly and that Waterways were approximately a quarter of the way through the works.

3. Review of Stage 2 Construction Environmental Management Plan sub-plans

Mike advised the group that under the project’s Infrastructure Approval the Traffic, Access and Transport and Noise and Vibration sub-plans must be prepared in consultation with the CCC, the Bega Valley Shire Council and the Environment Protection Agency (EPA). These sub-plans will be sent to Environmental Representative for endorsement prior to being submitted to the Secretary of the Department of Planning and Environment (DP&E) for approval. It is envisaged that these sub-plans will not be approved until late February.

4. Traffic, Access and Transport sub-plan Rob Davis introduced himself as the Project Manager and Tomas Rooney as Lead Engineer for Waterway Constructions. Rob provided an overview of the sub-plan as follows:

Plan purpose/overview

Truck routes - proposed routes for 19m semi-trailers and articulated vehicles, 12.5m heavy rigid vehicles and 18.7m truck and dog, and for medium rigid vehicles and small rigid vehicles

Hours, duration and truck movements per day

Marine construction and vessel mooring zones

Minimising disruption to Port businesses

Pedestrian access arrangements

Managing public safety.

Transport routes Rob discussed the proposed routes using Calle Calle, Chandos, Museum, Barclay and Mitchell streets. Richard asked if there would be enough visibility at the intersection of Imlay and Wirriga Streets as this is quite dangerous. Rob advised he will review these routes and this intersection with his team. Greg confirmed with the group that traffic and transport assessment has been undertake to confirm safe access. Hours and truck movements per day Rob advised there will be up to 20 movements per day on some days such as concrete pours taking place but this would not happen every day. John asked who the concrete suppliers will be for the project. Rob advised that Waterway Constructions is currently negotiating this. It was also noted that truck drivers will undergo the site specific induction which included truck routes.

Management measures The following management measures were discussed:

Providing delivery instructions and access routes to suppliers along with purchase orders or provided separately prior to dispatch of materials for delivery

Providing regular suppliers (i.e. concrete trucks) with a site specific truck induction

Ensuring delivery vehicles do not park on public roads, and instead park within the Project site boundary

Developing a Vessel Interaction Management Plan to manage barge movements to and from the Port/Construction Site

Preparing anchor layouts for the main barge spreads and provide to Port Stakeholders as part of ongoing consultation

Ensuring regular consultation with the Port of Eden Harbour Master during construction to ensure maintenance of safe navigation for shipping.

Page 3 of 5

Site deliveries and access to Shelly Beach was discussed as well as managing safety by keeping pedestrians separate from vehicles. The marine works area/zone was discussed with marker buoys on anchors. These drawings will be updated regularly and provided to the Harbour Master.

Richard asked about the pedestrian crossings at the Port and that he had witnessed pedestrians nearly being hit by vehicles. Greg advised he would follow up on ownership of the different crossings at the Port and would advise them of the near misses.

Noise monitoring Construction noise levels during piling will be monitored via a combination of attended (for the first two weeks of piling) and unattended (throughout the duration of piling) noise measurements. Monitoring will include:

Operator attended 15 minute measurements both during and outside piling activities at locations representative of the nearest monitoring locations and sensitive receivers for the first two weeks of pile driving works. The date, time and location of monitoring will be recorded, in addition to the name of the person conducting the monitoring and details of site activity, environmental noise characteristics and weather being noted.

Unattended background noise measurements in consideration to AS1055.1. Monitoring will be continuous over the period of piling. The noise loggers with telemetry reporting will upload and save data every 15 minutes, to allow for remote viewing through a password protected website.

Rob showed the CCC images of the Casilis barge and how piling will be done on the barge, the Calliope barge which is due to arrive closer to piling commencement, and the Kochi barge.

Leanne asked how many piles will be going into hard rock. Rob advised that it is expected that they will be hitting hard rock for the on-shore bollards and some of the piles on the wharf. However, a smaller hammer will be used for some of these piles reducing noise impacts. Tony noted that when piles hit hard rock, drilling is then undertaken. Respite periods Rob discussed respite periods as follows:

Planned respite from pile driving for a 1 hour duration between 12pm and 2pm

Page 4 of 5

Non-scheduled respite during natural breaks in construction activities, such as while resetting for piles

Moving barge/rig position

Setting up the gate

Rigging the pile for lifting

Lifting the pile into the gate

Disconnecting the pile (rigging gear)

Lifting the hammer onto the pile

Driving the pile (20 min to 90 min)

Two crib breaks per day. Mike advised that there are 135 piles to be driven and that some days only one pile may be driven. Tony advised there will be days when only set up will take place and there may be days when more than one pile will be driven. Gail noted that some businesses at the Port are not open after 3pm. Leanne asked the possibility of modifying the program and being flexible to business owners. Rob advised that Waterway Constructions will accommodate businesses as much as possible whilst still adhering to the program. John asked how loud the piling will be. The meeting discussed the piling previously undertaken at the Navy Wharf, and noise type and loudness. Vibration and testing Rob discussed the following:

Current predicted vibration modelling (based on the modelling previously done by Pacific Environment Limited (PEL) shows that vibration levels should be well below the guidelines

A Senior Acoustic Engineer from PEL will undertake vibration testing at the commencement of piling over a two week period to confirm predicted vibration levels

Testing will include measurements at decreasing distances from the nearest sensitive receivers toward the piling activities to estimate site-specific vibration levels.

Testing will involve the following steps:

Taking measurements using a vibration monitor with a triaxial accelerometer which will be coupled to the ground and/or structures

Determining the vibration dose values and peak particle velocities in accordance with Assessing Vibration: A Technical Guideline (DEC 2006)

Reporting, including date, time and location of monitoring, the name of the person conducting the monitoring, the peak particle velocity and vibration dose value.

Following completion of testing, a report, summarising the findings compared to the relevant guideline vibration levels, will be completed. Mike discussed utilising PEL through the EIS period and dredging. Rob noted that if there are higher than predicted levels of vibration other mitigation measures may be investigated and implemented after the testing period. Leanne asked if the same consultation will be in place as there was for the dredging. Coral advised this will be the case. Management measures The following management measures were discussed:

Implementation of respite periods (planned and unplanned)

Where possible, plant and equipment will be selected that can be fitted with options to minimise noise such as covers, mufflers, shrouds, etc

Page 5 of 5

Plant and equipment will be turned off and not left idling when not in use

Plant and equipment will be well maintained and serviced regularly to ensure it is not generating excessive noise

Use of high pressure washes to green cut concrete instead of using pneumatic scabblers

A concreting work method statement will be developed with consideration for minimising noise, such as care to be taken not to contact the pile with the concrete pokers during the concrete works

Site induction protocols will include awareness of noise generating activities and mitigation measures that are to be implemented

Piling work method statement shall be developed and implemented during piling works

Soft-start procedures for piling operations will be developed and implemented during piling works

Noise monitoring will be undertaken during piling activities

The community will be notified by the department in the lead up to noise intensive activities commencing such as piling

Works will be scheduled wherever possible to minimise the number of noisy plant and equipment operating at any one time.

Mike noted that by having a soft start procedure for piling the noise levels will gradually increase as the pilling increases from half blows to full blows.

6. Questions Glenn noted that larger piles to be delivered by water and stored at the laydown area at the Navy Wharf with only some of the smaller piles to be delivered by road. Leanne asked if mid-April is a definite commencement date for piling. Rob advised that this date is highly likely. Glenn noted that delivery of the piles is the critical path for the project. Simon noted that DP&E approval of plans will be occurring concurrently and that DP&E has been notified that these plans will be submitted shortly for their review. John asked if scour protection was running to schedule. Mike advised that scour protection works are on schedule to be completed in late January - early February and there will be a slight lull in works before Stage 2 commences. Glenn advised the sweeper dredge will come back at the end of the project to flatten out any lumps on the seedbed caused by the piling barge anchoring. Gail asked if work activities will have to be reduced with the arrival of cruise ships in the next week. The meeting discussed the exclusion zone in place around the divers and the works. Glenn noted that a large number of deliveries to site had been made to minimise the number of vehicles at the Port on a cruise day.

7. Next steps

Simon advised attendees that they will be sent the draft minutes and presentation for review and if they have any queries to direct these to Coral. Simon reiterated that the sub-plans once endorsed by the ER will then be submitted to the Secretary of DP&E for approval.

8. Next Community Consultative Committee meeting

Simon advised that the next CCC meeting will be held on 31 January 2018 and thanked the CCC for attending. Gail asked about the project shutting down over the Christmas period and was advised this will be from 22 December to 8 January. The meeting closed at 7.05pm.

1 Eden Breakwater Wharf Extension – Construction Piling Noise and Vibration Monitoring Program

Waterways plans to conduct piling including vibratory and impact piling during standard construction

hours over an estimated 40 week period, with an anticipated start of Q2 2018.

The Infrastructure Approval requires a Noise Monitoring Program for the piling works. The Construction

Environmental Management Plan (CEMP) for the works requires vibration testing to confirm levels at

sensitive receivers as a result of the piling activities.

This program has been prepared with consideration to the requirements of the Infrastructure Approval

and CEMP. This program will be used to confirm vibration levels and monitor noise at surrounding

sensitive receivers and structures in Eden, and assist Waterways in the management of noise and

vibration impacts.

2 Scope of Work

Our proposed Scope of Work for the Project is outlined in the following sections.

Project Inception

Project kick-off meeting (teleconference)

Preparation of monitoring safety documentation

Preparation of monitoring equipment

Baseline Noise Environment

The background noise environment will be confirmed based on the monitoring completed for the Port of

Eden Redevelopment Noise, Vibration and Air Quality Assessment (Pacific Environment 2016) and the

more recent monitoring program (September to November 2017) undertaken for the Stage 1 works

(Pacific Environment 2017). A brief report will be provided, and will include review of:

Operator attended 15 minute measurements during the proposed day time construction hours, at

locations representative of the monitoring locations and sensitive receivers.

Previous unattended background noise measurements (Pacific Environment 2016, 2017).

Intensive Piling Noise and Vibration Monitoring

Prior to commencement of piling activities a Senior Acoustic Engineer will be deployed to Eden, full

time, to assess noise and vibration from piling activities. It is anticipated that intensive monitoring will be

completed within a 2 week period from the commencement of piling.

The objectives of the intensive monitoring will be as follows:

Identify potential noise and vibration impacts from piling activities.

Confirm piling vibration levels and level of impact at sensitive receivers

Simultaneous confirmation of piling noise emissions and level of impact at sensitive receivers.

Investigate any noise and vibration related complaints

Provide noise and vibration mitigation and management recommendations as required.

Prepare an assessment report of noise and vibration impacts for the first 2 weeks of piling.

Vibration Testing (2 week intensive)

It is understood that up to 100 piles will be driven along the length of the breakwater wharf, and 16 larger

piles for the dolphin structures. A Senior Acoustic Engineer will undertake vibration testing to confirm

vibration impacts from piling activities. This would include vibration testing at increasing distance from

the piling activities towards sensitive receivers (buildings and structures), in order to estimate site

specific vibration propagation and estimate site specific safe working distances.

Data will be collected during the first two weeks of piling, and will include:

Vibration testing to be conducted at increasing distanced from the piling activities towards

sensitive receivers and structures.

Vibration dose values and peak particle velocities will be determined in accordance with Assessing

Vibration: A Technical Guideline (DEC, 2006), and safe working distances established for the

activities.

Measurements will be completed using a vibration monitor with a triaxial accelerometer.

The accelerometer would be established with consideration to AS 2775. Mechanical vibration and

shock - Mechanical mounting of accelerometers.

Noise Monitoring

Noise Monitoring (2 weeks intensive) Pacific Environment will install telemetry noise loggers at two representative receiver locations for the

ongoing monitoring of the ambient noise environment and piling activities. These locations are

representative of noise affected receivers in surrounding catchment areas and are presented in Figure

1. The loggers will remain on site for the duration of piling activities, and data will be used in conjunction

with baseline noise information conducted for previous stages of the project, including the dredging

background noise investigations. This data would be supplemented by attended noise monitoring during

this period to validate predicted impacts from piling activities for the intensive two week period.

Data will be collected for the duration of piling, and will include:

Operator attended 15 minute measurements during daytime periods at locations representative

of the nearest monitoring locations and sensitive receivers during the initial 2 week monitoring

period.

Continuous unattended noise logging at two locations representative of the nearest monitoring

locations, consistent with the receivers identified in the Port of Eden Breakwater Wharf Noise and

Vibration Assessment (Pacific Environment 2016) and the Night Dredging Protocol (Pacific

Environment 2017).

Noise monitoring would be undertaken with consideration to the method detailed in Australian

Standard (AS) 1055.1:1997 Description and Measurement of Environmental Noise.

Unattended and attended measurements will be performed using Class 1 sound level meters,

such as Acoustic Research Labs NGARA and NTI Audio XL2 hand held meters. These

instruments are able to provide 1/1 and 1/3 octave spectral analysis on statistical descriptors which

to assist with the removal of extraneous noise sources.

o The unattended noise loggers with telemetry reporting upload noise data every 15

minutes. The data is saved and available for viewing over password protected website.

Meteorological conditions over the monitoring period will be collected from the nearest Bureau of

Meteorology automatic weather station.

The intensive period is anticipated to be of 2 weeks duration, and it is envisioned that the bulk of the

attended monitoring to confirm the extent of noise impacts can be completed within this period of

monitoring. Following this period data collection and reporting will occur remotely.

review and analysis on a weekly basis with reports prepared on a monthly basis for the remainder of

the period of works.

Data will be collected for the duration of piling, and will include:

Unattended noise measurements at two locations. Site visit for instrument calibration check and

maintenance checks on a monthly basis.

Measurements will be performed using Class 1 sound level meters, such as Acoustic Research

Labs NGARA.

Logging equipment will be capable of real-time data upload to the cloud. Remote data download

will be completed and daily checks to ensure ongoing functionality of noise monitoring equipment.

Meteorological conditions over the monitoring period will be collected from the nearest Bureau of

Meteorology automatic weather station.

Monthly reporting of noise monitoring results.

o Piling activities are anticipated to be readily identifiable via remote data analysis.

3 Methodology

The determination of noise compliance and vibration impact involves monitoring and measurement to

determine the contribution of the piling noise sources excluding extraneous noise sources such as;

traffic, fauna (birds and insects) and other industrial noise sources, and determination of site specific

values of vibration over distance.

Baseline noise monitoring investigations completed to date as part of the Port of Eden Breakwater Wharf

environmental management reporting, including baseline investigations for the previous dredging works,

will be used to supplement current measurement data.

Vibration Testing

Intensive Vibration Monitoring The vibration testing methodology will involve the following steps:

Vibration testing to be conducted over a two week period at decreasing distances from sensitive

receivers and structures towards the piling activity (approximately 10 m to 250 m, dependent on

location suitability).

Measurements will be completed using a vibration monitor with triaxial accelerometer.

Accelerometer will be coupled to the ground/structures with consideration to AS 2775. Mechanical

vibration and shock - Mechanical mounting of accelerometers.

Vibration dose values and peak particle velocities will be determined with consideration to

Assessing Vibration: A Technical Guideline (DEC, 2006).

In the event of identification of vibration impacts above anticipated levels, a recommendation will

be made to reduce vibration levels via modification to the piling method.

Reporting will involve date, time and location of monitoring, name of person conducting the

monitoring, PPV and VDV.

Reporting A summary report will be prepared to fulfil the requirements of the CEMP for the intensive vibration

testing. The reporting will include:

Details of vibration testing methodology.

Testing results and observations.

Instrument set calibration certificates.

A summary of measured vibration levels with consideration to predicted levels.

A summary of any vibration management recommendations.

Remote data download via mobile internet (statistical descriptors for the standard monitoring intervals

eg LAeq, 15minute and LA1 1 minute) implemented to facilitate ongoing compliance assessment and review of

unattended noise levels in the event of a complaint. This can be used to remotely verify noise levels

within a shorter time period (within several hours of a complaint event).

Piling activities are anticipated to be readily identifiable through statistical analysis and observation of

trends. This will reduce the ongoing operational component of the monitoring, as data can be sourced

remotely and processing can be completed without ongoing presence of acoustic consultant.

Monthly reports will be prepared to fulfil the requirements of the CEMP. The reporting will include:

Details of monitoring methodology.

Monitoring results and observations.


Summaries of measured noise levels, including graphical presentation of all unattended noise

logging data, a summary of any complaints received, including their nature and time.

A summary of any additional noise mitigation measures implemented, and an evaluation of the

effectiveness of any response measures implemented.

The review and analysis of unattended monitoring data will include download, reporting and analysis of

measured noise levels and trends on a monthly basis with daily monitoring graphs presented and

analysed.
