1 Introduction

1.1 Purpose of this plan

The purpose of this Project Construction Environmental Management Plan (PCEMP) is to set out the

approach, processes and standards to manage environmental protection measures during the construction

of this project, which falls under the SMC being delivered by DM.

The purpose of this PCEMP is to provide consistency in terms of structure and delivery of environmental

management that is consistent with DM’s SMC Environmental Management Plan (EMP) and any RMS

requirements and best practice.

This plan has been developed to read in conjunction with the DM SMC EMP.

Works shall be implemented in accordance with the management measures and mitigation strategies set

out in this PCEMP.

This document has been produced in accordance with the requirements of the DM SMC EMP, the approved

Project REF, RMS Specification G36, the DM Quality Plan and the Downer accredited Integrated

Management System (IMS) which DM has adopted. These procedures are accessible via the DM Integrated

Contract Management System.

The processes, safeguards and mitigation measures defined within this PCEMP shall be implemented by all

parties either directly employed by DM or subcontracted and will apply to all activities associated on this

Project.

For more detailed and specific information regarding objectives and targets, aspects and impacts,

legislative requirements, DM training and awareness, communications, monitoring, corrective action,

incident management and document control; and how they are applied to the Project, refer to the DM SMC

EMP.

Contractors as a minimum will be required to comply with the requirements of this PCEMP and may

prepare their own CEMP as required providing it meets the requirements stated in this PCEMP.

1.2 Objectives of this plan

The objectives of this plan are to:

1) Provide an over‐arching methodology to be followed to manage and mitigate potential impacts environmental impacts during construction of this project; and

2) Provide specific guidance on how to manage specific environmental issues during the completion of common construction activities.

All management actions and procedures outlined in this plan have been developed with specific

consideration to the approved REF document and the DM SMC EMP and RMS G36M Specification.




1.3 Scope of works

This Project Construction Environmental Management Plan and sub‐plans have been prepared in accordance with Roads and Maritime QA Specification G36M and AS / NZS ISO14001. It has also been prepared to comply with all legislative requirements and the REF and Decision Notice determined for this work.

This PCEMP has been developed to be specific to Overtaking Lane Site 3 (OT3) of the Bells Line of Road project. This is for the construction of an overtaking lane on Bells Line of Road, between Tadrosse Lane to Pup Road.

This PCEMP forms part of the overall environmental management system and details environmental protection measures, including:

Before site establishment and work/construction;

During works/construction;

After works/construction (including any rehabilitation activities and maintenance of erosion and sediment controls).

In particular, this PCEMP:

Describes the Project in detail including activities to be undertaken;

Describes the environmental management roles and responsibilities of personnel;

Identifies environmental aspects and impacts associated with each activity of the Project;

Provides specific mitigation measures and controls that can be applied to avoid or minimise environmental impacts.

Project details

The project will include constructing a new westbound overtaking lane on Bells Line of Road, between Tadrosse Lane to Pup Road. (refer to Figure 1 below).

The works would provide widening of the existing westbound lane (southern side), including the provision of a sealed shoulder. In some areas, road widening would require batters and cuttings to be cut back and re‐shaped. Construction is expected to commence in mid‐2016 and would take around six months to complete.

The proposal would provide a new 1.53 kilometre long westbound overtaking lane (including a 980 metre overtaking lane, 90 metre diverge and 150 metre merge taper), with key features including:

A new 3.3 metre wide travel lane to the south of the existing road formation

A new road shoulder, varying between 1 and 3 metres on the westbound lane

New road surfacing (which involves cement stabilisation and spray seal of both the new and existing pavement) along the extent of the overtaking lane

New signage and line marking

Construction of roadside batters and drainage.




Up to six ancillary sites (AS) would be used during the construction of the proposal. Some ancillary sites

have multiple sub‐sites.

The general location of each ancillary site is outlined below:

Existing Environment

Flora and Fauna

The proposal would result in clearing of around 17,700 m2 (1.77 hectares) of native vegetation which is consistent with the State‐listed TEC Blue Mountains Shale Cap Forest in the Sydney Basin Bioregion. This includes around 14,000 m2 (1.4 hectares) of high condition intact vegetation which is consistent with the federally‐listed critically endangered ecological community Turpentine Ironbark Forest of the Sydney Basin Bioregion

This project is part of a larger program of works along Bells Line of Road. This project on its own does not

trigger referral to the Commonwealth as an action under the Environment Protection and Biodiversity

Conservation Act 1999 (EPBC Act). However, the overall program of works (Kurrajong Heights to Mount

Tomah) has been referred to the Commonwealth Department of the Environment due to the cumulative

loss of Turpentine Ironbark Forest of the Sydney Basin Bioregion (vegetation listed as critically endangered

under EPBC Act), across the separate overtaking lane proposals across the Bells Line of Road. Further

information regarding this Approval is included within the Biodiversity Management Plan (Appendix C).

No threatened flora species have been confirmed and the likelihood of presence of a number of threatened plant species has been assessed as low. All species recorded at the proposal area are common, widespread species and are present in adjacent areas outside of the proposal area.

The disturbed roadside areas within the proposal area have an abundance of weed plants. There is potential for noxious and /or environmental weed species to be spread during construction.

Assessments of Significance were carried for ten fauna species under the Environmental Planning and

Assessment Act 1997 (NSW) and Environment Protection and Biodiversity Conservation Act 1999 (Cth),

concluding that there is unlikely to be a significant impact on any threatened fauna.

There are no primary feed trees for Koala within the proposal area, i.e. Monkey Gum, however there is a moderately high density of the secondary feed tree Grey Gum and evidence of Koalas reported on the south side of the road. Considerable large areas of potential habitat occur to the north and south of the proposal area, which are contiguous with the areas being impacted. The clearing of habitat will occur along the edge of very large patches and is not expected to be a significant loss of feed trees for the local population. There may be a short‐term impact to the movements of the Koala during the breeding season, however the impacts to the foraging life‐cycle is minor. The project would require the removal of about 44 hollow‐bearing / habitat trees.

The proposed widening of the road may lead to a reduced connectivity and increased risk of road‐kill at a portion of the proposal area.

Further information, including the mitigation measures detailed for flora and fauna and diagrams highlighting areas of sensitive vegetation are detailed within the Biodiversity Management Plan in Appendix C.

Noise and vibration

The proposal is located in an area consisting primarily of rural residences and agricultural enterprises. A total of 17 sensitive residential noise receivers have been identified within the proposal area. The closest is located about 30 metres from the existing road edge.

The REF indicated the potential for exceedance of the noise goals at each of the receiver locations during each phase of the works. Construction noise mitigation measures were recommended to be applied for




these locations. Given the linear nature of the work, noise levels that exceed the NMLs would not be expected to occur for long periods and worst case noise impacts would not be realised for the duration of construction.

Mitigation measures are detailed in the Noise and Vibration Management Plan in Appendix D.

Non‐Aboriginal Heritage

Four heritage items within 10 kilometres of the study area were identified in the REF:

• Greater Blue Mountains (World Heritage List and National Heritage List);

• The Mount Tomah Road Cuttings (item number 4310585), listed on the Roads and Maritime s170 register;

• Blue Mountains LEP ‐ Mount Tomah and environs heritage conservation area (MT002) and The Jungle (site only, MT010) located within the conservation area curtilage. These are both at least 10 km from the project.

The study area has been assessed as having low historical archaeological potential and it is very unlikely

that intact historical archaeological structures or deposits would be impacted by the proposal.

Aboriginal Heritage

The proposal is located near the traditional boundaries associated with the Wiradjuri, Gundungurra and Darug people. The proposal is located within an area that is known as a ‘zone of interaction’ where they intermingled (Bowdler cited in Comber, 2012). While the Wiradjuri, Gundungurra and Darug people had their own distinct spiritual beliefs and creation stories, they could communicate with each other (Comber 2009). Each nation moved within their defined territories along well‐established pathways.

A search of the AHIMS database was undertaken on the 14 April 2014 for sites within a one kilometre radius of the Bells Line of Road between Kurrajong Heights and Mt Tomah, including the proposal study area. Twenty five recorded sites were identified between Kurrajong Heights and Mount Tomah. These included 10 shelter sites, eight artefact sites, four grinding groove sites, one combined art and grinding groove site and one art site and one non Aboriginal site recording.

Of the recorded sites, none were located within 200 metres of the proposal area.

The REF determined that the project would not have direct impacts on any known Aboriginal heritage sites.

Water quality and soils

The proposal is situated along a section of Bells Line of Road that runs along a ridgeline. This ridgeline forms the boundary between the Grose and Colo River catchments to the south and north of the proposal respectively. The proposal area lies approximately 1.5 kilometres south of Wheeny Creek, a tributary of the Colo River and 760 metres north of Wilderness Brook, a tributary of the Grose River, in Kurrajong Heights. No permanent water bodies or natural drainage lines are located within the proposal area. Therefore, the proposal does not cross any major waterways and is not impacted by regional flooding.

During construction, potential impacts on water quality would be focused on erosion and sedimentation associated with clearing and earthworks. This could increase turbidity and result in a decline in the water quality of receiving waters. There are five existing culverts, which require extension for the proposal. These works have the potential to cause water pollution due to earthworks in proximity to stormwater and drainage lines.




Potential chemical or oil leaks and accidental spills associated with construction machinery could also cause localised contamination of soils.

There are no likely impacts on groundwater quantity or quality as no groundwater extraction would be

required for construction of the proposal and the water table would not be intercepted during excavation

work.

Safeguards and management measures have been proposed to address these potential impacts in Appendix B.

Air quality

There is potential for air quality emissions to cause nuisance impacts to sensitive receivers located close to

the proposed work. Seventeen residences are located adjacent to the proposal area.

Safeguards and management measures have been proposed to address these potential impacts in Appendix B.

Waste and resources

The proposed work would generate an estimated 4600 m3 of soil and rock material from the removal and reshaping of roadside batters and embankments. Construction would also generate waste streams typical of road construction work, including green waste; waste road infrastructure (eg signposts); oil and grease; waste from the demolition and general wastes and sewage from site compounds and offices.

DownerMouchel prescribes the management of contractors pursuant to DA‐ZH‐PR022 Visitor and

Contractor Management to ensure that Contractors undertake their activities in a manner which meets the

expectations of DownerMouchel’s Policies and Procedures.

Contractor Evaluations will be conducted prior to engagement and/or when there is a significant change to

scope of work being performed using DA‐ZH‐FM022.3 Contractor Evaluation Form pre‐assessment to

ensure that the contractor achieves an ‘Acceptable’ rating or approval which is ‘Conditional’ to the use of

DownerMouchel’s management system.

Specifically, contractors of DownerMouchel must register their attendance when entering or leaving the

site, notify their DownerMouchel Host or Project Manager before proceeding on to the site; and complete

the relevant inductions pursuant to DA‐ZH‐PR022 Visitor and Contractor Management.

All Contractors must obtain evidence of the online induction undertaken and present the induction

evidence/receipt to DownerMouchel Manager prior to commencement of work.

DownerMouchel Managers will issue individual Contractors with a Contractor Induction / ID Card, valid for

one year from the date of issue.

DownerMouchel will ensure that all Contractors are aware of their environmental responsibilities and

comply with the requirements of this PCEMP when performing works under the contract. This will be

achieved by:




Including the relevant environmental requirements in the contract documents;

Requiring the Contractor to develop their own CEMP for the project, which must include all relevant Contractor requirements from the REF and this PCEMP;

Requiring the Contractor to develop a (or a series) of Erosion and Sediment Control Plans (ESCPs) for the works and update as required;

Clearly communicating the contractors’ responsibilities for ensuring compliance with relevant environmental legislation, approvals, licences and permits;

Providing adequate environmental induction training;

6 Emergency preparedness and response

In the event of an incident that may have resulted in a near miss or an impact to the environment or

community, contractors must implement actions to contain the incident and advise the DM Supervisor

immediately and without delay. The Supervisor will then advise the DM EM and other senior personnel

immediately and the processes detailed below will be followed.

6.1 Incident Reporting and Investigation

In the event of an incident that may have resulted in a near miss or an impact to the environment or

community, DownerMouchel employees and contractors are expected to respond appropriately in

accordance with DA‐ZH‐PR006 Incident Reporting and Investigation Procedure.

Incidents that cause or threaten Material Harm to the environment must be externally notified to each

relevant authority by DownerMouchel Management immediately in accordance with Part 5.7 of the POEO

Act. The relevant authorities that need to be notified are listed in Table 6‐1.

Harm to the environment is material if:

It involves actual or potential harm to the health or safety of human beings or to ecosystems that is not trivial, or

It results in actual or potential loss or property damage of an amount, or amounts in aggregate, exceeding $10,000 (or such other amount as is prescribed by the regulations), and

Loss includes the reasonable costs and expenses that would be incurred in taking all reasonable and practicable measures to prevent, mitigate or make good harm to the environment.

For the purposes of Section 5.7 of the POEO Act, it does not matter that harm to the environment is caused only in the premises where the pollution incident occurs.

6.2 DownerMouchel Incident Reporting and Investigation

DownerMouchel have developed an Incident Reporting and Investigation Procedure (DM‐ OHS‐PR‐106) to

ensure incidents are managed and investigations occur in a systematic manner and that corrective actions

are identified and implemented. This reporting and investigations process will also be conducted in

accordance with DA‐ZH‐PR006 Incident Reporting and Investigation Procedure.

Where an incident occurs it may have resulted in the activation of the emergency management process, for

this reason this procedure should be read in conjunction with DM‐OHS‐PR‐107 Emergency Management.

Additionally, where there has been a significant injury or fatality this procedure shall also be read in

conjunction with DM‐OHS‐ WI‐106‐010 Managing Serious Injuries & Fatalities or Dangerous Events & DA‐

ZH‐PR151 Crisis Management.

This procedure applies to all DownerMouchel personnel and contractors and consultants procured by them

and visitors to DownerMouchel controlled sites.

6.3 RMS Incident Reporting and Investigation

DownerMouchel will notify RMS verbally as soon as practicable and, in any case in writing within 24 hours,

of any incident that has been reported to the EPA under Section 9.1 of this EMP and Part 5.7 of the POEO

Act.

All other incidents will be reported to RMS verbally as soon as practicable and, in any case, in writing within

24 hours of the incident occurring and coming to your attention, including lessons learnt from each

environmental incident. All efforts must be undertaken immediately to avoid and reduce impacts of the

incident and suitable controls put in place.

All environmental incidents, including ‘pollution incidents’; will be managed and reported in accordance

with the RMS Environmental Incident Classification and Reporting Procedure and RMS Environmental

Incident Report.

7 Risk management

Throughout the project, risks will be identified, assessed and controlled through the use of a number of

different tools outlined within DA‐ZH‐PR028 Zero Harm Risk Management, specifically risk assessments will

be recorded on form DA‐ZH‐FM028.8 Construction Risk Assessment Workshop.

The identification of the significant environmental aspects and impacts that could eventuate during

construction of the project is central to the selection of appropriate environmental safeguards.

Aspects and impacts will be identified for all construction activities that:

Have the potential to cause the discharge or release of pollutants to water, air, or land;

Impact on flora, fauna or heritage;

Have the potential to create change to the environment, including air and noise; and




Generate wastes.

The ongoing determination of environmental aspects and impacts will be achieved through the risk

management process, which results in the development of a list of environmental risks (aspects and

impacts), and a corresponding risk mitigation strategy and risk ranking for each risk. Each environmental

risk is categorised, based on the following:

The environmental aspect;

Relative scale of the potential impact;

Type of potential impact; and

Likelihood of occurrence.

The following risk assessment matrix Table 7‐1 forms part of the Zero Harm Risk Management Procedure

(DA‐ZH‐PR028), will be used when assessing environmental risk on the SMC. Table 7‐2 outlines the

Likelihood rating and Table 7‐3 outlines the consequences of harm as a result of environmental risks.




Table 7‐1 Risk Assessment Matrix

Table 7‐2 Likelihood Ratings ‐ What is the likelihood of the selected consequences occurring?




Table 7‐3 Consequence Ratings

7.1 Site Planning and Risk Assessment

In terms of risk, the identification of significant impacts associated with the aspects of this project are

detailed in Table 7‐4 below.

The aspects, impacts and potential risks associated with key construction activities have also been

identified in the EPP for medium risk (Appendix B) and in the Management Sub‐Plans for higher risk

(Appendix C and Appendix D).

The EPP and sub‐plans provide a range of measures that will be implemented to:

• Control the occurrence of the identified environmental impacts;

• Protect the environment from harm;

• Safeguard the local community;

• Satisfy the environmental requirements of the Project and relevant agencies; and




• Provide positive environmental offsets to unavoidable environmental impacts (where practical and cost effective to do so).

A program of routine maintenance will be conducted on environmental controls. Daily inspections of work

areas by Project Engineers and Site Foreman and weekly (minimum) inspections by the Environmental

Manager will provide a means for identifying maintenance requirements before they reach a critical stage.

Risk Assessment Workshop

To further develop and / or review the risk assessment, each site / activity with an Environmental Impact

Assessment (EIA) (this includes REF’s) is to conduct a facilitated risk assessment workshop. The facilitated

risk assessment workshop will be recorded on the DA‐ZH‐FM028.8 Construction Risk Assessment Workshop

form.

The purpose of the facilitated CRAW is to identify and address the environmental risks associated with

these and other activities you propose to undertake, and develop risk mitigation and management

strategies to eliminate or reduce risk exposure. These risk mitigation strategies must be consistent with the

environmental controls and management measures listed in the Protection Plans and REF.

Participants of the facilitated CRAW will include site management staff, the Site Environmental

Representative, and any personnel who will be performing the works including contractors. RMS

representative will be advised of a scheduled facilitated CRAW at least seven (7) days prior to the

workshop.

The scope of the facilitated CRAW will include but not limited to:

Review of REF prepared for the Work;

Risk assessment of the potential environmental impact identified in the REF;

Evaluation of methods to reduce the environmental risk;

Assessment of the environmental controls required; and

Assessment of the actions required to obtain the appropriate approvals.

Any perceived cumulative impacts caused from other projects in the vicinity of OT3.

8 Environmental protection

Environmental Protection Plans and Management Plans

A Biodiversity Management Plan and a Noise and Vibration Management Plan have been prepared to

address the project specific requirements and mitigation measures required to minimise impacts to flora

and fauna and noise and vibration. These are included within Appendix C.

For the remaining environmental aspects, Appendix B contains an EPP for each of the medium risk

environmental aspects that may be impacted during the construction of the work packages. These include

the identification of environmental management measures, the timing of implementation, responsible

person and how each measure would be implemented and communicated.

The mitigation measures in the EPPs have arisen from requirements of the REF, SMC EMP, RMS

Specification G36M and RMS guidelines.

The EPPs set out the environmental monitoring and management tasks to be undertaken prior to

construction, during construction and post‐construction. Where applicable, further specific control

measures and safeguards will be incorporated into the Environmental Work Method Statements for

higher risk activities.

Environmental Work Method Statements

EWMSs will be developed by DownerMouchel for high risk activities to be undertaken on site with the

potential to impact sensitive areas. For the BLoR projects, the key high risk activity will be the clearing of

vegetation that is subject to the Federal Approval issued on November 3, 2015. The key EWMSs to be

developed for the project will be (but not limited to):

Clearing and grubbing;

Transverse drainage replacement or extension; and

Survey and set out works.




9 Evaluation and performance

9.1 Monitoring / inspections

DM will undertake regular site environmental inspections to assess the adequacy and effectiveness of the

environmental mitigation measures as per DA‐ZH‐PR116 Zero Harm Inspections and Observations. Where

required, the contractor will provide appropriate resources to undertake these inspections with DM.

Site inspections by RMS Regional Environmental Staff (RES) will also be undertaken periodically. DM and

the contractor where appropriate will provide resources to undertake these inspections with RMS.

Environmental inspections are detailed further in Section 13 of the DM SMC EMP.

There are no quantitative monitoring requirements for the project, however visual monitoring for

performance will occur through the environmental inspections and Zero Harm Audits detailed within

Appendix B.

9.2 Records

The Project will maintain legible records to demonstrate compliance with this CEMP and the requirements

of the Federal Approval. Records will be maintained in accordance with the Downer Records Management

Procedure (DA‐QA‐RP006) and will include, but not limited to:

Monitoring/inspection reports

Internal audit reports

External audit reports

Reports of environmental incidents, other environmental nonconformities, complaints, action taken and follow‐up action (including complaints register)

Minutes of meetings

Induction training records

Register of Erosion and Sediment Control Plans

These records will be held for at least five years after the date of completion of the Project and will be

available to RMS staff and to authorised NSW EPA/OEH or Federal Department officers on request.

9.3 Compliance tracking

As required by Federal CoA 9, a tracking register will be maintained for the project to assess compliance

with the Federal Approval conditions. Within three (3) months of every twelve (12) month anniversary of

the commencement of construction, Roads and Maritime will publish a report on their website addressing

compliance with each of the conditions of this approval, including implementation of any management

plans as specified in the conditions.

Documentary evidence providing proof of the date of publication and non‐compliance with any of the

conditions of this approval will be provided to the Department at the same time as the compliance report

is published.




9.4 Non conformance

Environmental non‐conformances and corrective actions will be detected through processes such as

monitoring, inspections (internal and external), audits (internal and external) and receipt of complaints.

Environmental non‐conformances and corrective actions will be resolved according to the Corrective and

Preventative Action procedure (DA‐QA‐PR005).

The process for managing environmental non‐conformances will be as follows:

When an environmental non‐conformance is detected, the nature of the event will be evaluated by the EM or ESR, the effectiveness or need for new/additional controls will be reviewed and strategies identified to prevent recurrence. Corrective actions will subsequently be identified and entered into the Corrective Action Register. The Corrective Action Register will detail the non‐conformance, the corrective and preventative actions proposed and the responsibilities and timing for completion of the actions;

Where the environmental non‐conformance is associated with an inspection, audit or monitoring event, the actions will be linked to the record of that event;

Where a new non‐conformance is raised by RMS during a site inspection, or audit, a Nonconformity Notification may be issued.

Nonconformity Notifications issued by RMS will be handled in the same manner as any other non‐conformances.

Once an action is completed, the register will be updated to close the action including input of comments and completion date; and

The Corrective Action Register will be reviewed monthly by the Environmental Team (EM, ESR) to ensure actions are being completed in time.

Corrective Action Requests

If surveillance, site inspections or an audit by RMS identifies that the PCEMP does not comply with the

provisions of the contract, or RMS identifies a major environmental risk, a Corrective Action Request (CAR)

may be issued.

Environmental non‐conformances that might trigger a CAR might include:

Failing to comply with the environmental regulations or license/permit conditions

A serious breach of RMS specification requirements

Carrying out an unsafe work practice that has the potential to cause harm to the environment (i.e. near misses)

Activities that have caused actual harm to the environment not permitted by the project, or covered in the environmental assessment documentation

Deficiencies or concerns raised by client representatives and/or by state and local authorities or agencies

The process for managing a CAR issued by RMS will be the same as any non‐ conformance.




Once the CAR is rectified, the completed CAR is to be returned to RMS with seven (7) days after the CAR is

issued to DM; and the Corrective Action Register updated to close out the action.

Incident Action Close Out

In addition to the above, where an issue is of more serious nature, has been identified repeatedly or

constitutes a breach of regulatory obligations, the following will apply:

When required, the work on the identified operation or site will be stopped until remedial action is taken to eliminate the issue;

An incident report will be completed and incident logged in the incident register;

The incident report will be forwarded to the Program Manager and, if deemed non‐ compliance with the RMS Specification G36M, or RMS Project Determination;

The incident will be reported in monthly management reports to RMS;

Where the issue has been identified in an audit, a Non Compliance Report (NCR) will be used instead of an incident report, where this is considered appropriate by the Auditor.

Tracking of environmental non‐conformances and associated corrective actions will be the responsibility

of the EM or as delegated by the EM.

1. Introduction This Biodiversity Management Plan (BMP) forms part of the Project Construction Environmental

Management Plan (PCEMP) for the construction of overtaking lane Site 3 (OT3) on the Bells Line of Road

between Tadrosse Lane and Pup Road (the Project) being delivered by DownerMouchel (DM) as part of the

Stewardship Maintenance Contract with the Roads and Maritime Services (Roads and Maritime).

The purpose of this BMP is to describe how potential impacts associated with biodiversity shall be managed

during pre‐construction, construction, and post‐construction activities associated with the project. It is also

prepared in accordance with the requirements of the Federal approval (EPBC 2014/7346) issued by the

Department of the Environment on 3 November 2015. This approval was issued under sections 130(1) and

133 of the Environment Protection and Biodiversity Conservation Act 1999 (Cth) for the safety works along

Bells Line of Road, between Mount Tomah and Kurrajong Heights NSW.

Works shall be implemented in accordance with the management measures and mitigation strategies set out

within this Sub‐Plan.

This Sub‐Plan complies with and supplements the OT3 CEMP, and has been developed in accordance with

Biodiversity Guidelines: Protecting and managing biodiversity on RTA projects (Biodiversity Guidelines).

The processes defined within this Sub‐Plan shall be implemented by all parties either directly employed by

DM or subcontracted and will apply to all activities listed in the SMC.

2. Objectives The Biodiversity Guidelines prepared for the former NSW Roads and Traffic Authority (now NSW Roads and

Maritime Services) identifies biodiversity as ‘the variety of life forms, including flora and fauna, the genes

they contain and the ecosystems in which they live’.

The objectives of this plan is to:

1) provide an over‐arching methodology to be followed to manage and mitigate potential impacts to

biodiversity during the construction of OT3;

2) to provide specific guidance on how to manage biodiversity during the completion of OT3; and

3) provide a framework that complies with the conditions of the Federal Approval EPBC 2014/7346.

All management actions and procedures outlined in this plan have been developed with specific

consideration to the former RTA’s Biodiversity Guidelines.




3. Existing environment

To assess potential impacts to the existing environment, a Review of Environmental Factors was prepared in September 2015. As part of this, a Biodiversity Assessment paper was prepared. The outcomes of these assessments are outlined below.

The proposal area is entirely within an existing road corridor, however the majority of the road reserve that is unpaved is heavily vegetated and generally undisturbed. Beyond the road reserve there are around six properties adjacent that undertake horticultural practices and these areas are largely cleared and have large farm dams. There are also smaller residential plots in the central portion of the proposal areas consisting of exotic trees and shrubs and changes to the native vegetation as to be expected for these premises. In most other areas the native vegetation remains largely intact with large blocks of remanent vegetation that is connected to the conservation park system located around 1‐2 kilometres away. The Bells Line of Road has fragmented the mostly contiguous landscape of vegetation on either side. Native fauna move north‐south through this road corridor between the landscape of the Blue Mountains and Wollemi National Park areas. Data on fauna roadkill contain frequent records of roadkill between Kurrajong and Mount Tomah. These records include Spotted‐tail Quoll and Koala, both species listed as vulnerable on the EPBC and TSC acts.

3.1 Vegetation

3.1.1 Threatened ecological communities

Native vegetation in the study area is consistent with the following Commonwealth and State listed threatened ecological communities:

Blue Mountains Shale Cap Forest in the Sydney Basin Bioregion (Endangered on TSC Act)

Turpentine – Ironbark Forest in the Sydney Basin Bioregion (Critically Endangered on EPBC Act).

The distribution of vegetation communities for OT 3 is illustrated in Figures 3‐1 to Figure 3‐4.

The vegetation includes a mix of native flora species found on sandstone and shale soils, and it is likely that the study area is within a transition zone between shale and sandstone soil landscapes. The Blue Mountains Shale Cap Forest was found more in the western end of the proposal area with the Turpentine–Ironbark Forest found more within the eastern end. The canopy supports a mix of species including Turpentine (Syncarpia glomulifera), Smooth‐barked Apple (Angophora costata), White Stringybark (Eucalyptus globoidea), Mountain Mahogany (Eucalyptus notabilis) and Red Bloodwood (Corymbia gummifera). The native understorey has been removed in several patches of vegetation within the proposal area. Patches supporting an intact native understorey were limited to areas of private property outside of the proposal area to the north of Bells Line of Road. These areas are generally dominated by Parramatta Wattle (Acacia parramattensis), Graceful Bush‐pea (Pultenaea flexilis), Sweet Pittosporum (Pittosporum undulatum) and a groundcover of forbs and grasses.

The proposal area contains areas of Turpentine Ironbark Forest at the eastern end and areas of Blue Mountains Shale Cap Forest at the western end. Areas of Turpentine Ironbark Forest include fragmented patches of high and moderate condition vegetation. Moderate condition vegetation at the eastern end includes a thin strip of under scrubbed vegetation along the southern edge of the road which appears to be regularly maintained / slashed. This area has been excluded from the federal listing due to the missing mid‐storey/shrub layer, reduced condition and somewhat isolation of the patch. High conditions of federally listed




vegetation include maintained and/or disturbed areas of vegetation in the road reserve and on private property.

Areas of Blue Mountains Shale Cap Forest (federally listed) are present at the western end of the study area

and include larger intact patches along the road reserve and on adjacent private property. This community

is distinguished by the higher number of ferns, herbs and shrub species such as Native Indigo and Veined

Mock Olive. The proposal would result in clearing of around 17,700 m2 (1.77 hectares) of native vegetation

which is consistent with the State‐listed TEC Blue Mountains Shale Cap Forest in the Sydney Basin Bioregion.

This includes around 14,000 m2 (1.4 hectares) of high condition intact vegetation which is consistent with the

federally‐listed critically endangered ecological community Turpentine Ironbark Forest of the Sydney Basin

Bioregion. The areas of vegetation loss within the proposal area are shown in Appendix A – Extent of

vegetation clearing.

Assessments of Significance under the EP&A Act for the proposal have concluded that direct and indirect

impacts to the vegetation communities resulting from this proposal on its own are not significant.

3.1.2 Threated flora species

A total of 44 threatened flora species have been previously recorded or listed as having potential to occur in the locality. Of these 44 species, none were recorded in the study area during the survey. All species are considered to have either have a low or unlikely potential to be present.

3.1.3 Weeds and pathogens

Vegetation along the road corridor edge was found to contain a number of weeds declared as a noxious weed for the Hawkesbury LGA, with moderate to high infestations of the following species noted:

• Blackberry (Rubus fruticosus);

• Montbretia (Crocosmia x crocosmiiflora);

• Montipellier Broom (Genista monspessulana);

• Privet species (Ligustrum sinense and L. lucidum)

St John’s Wort (Hypericum perforatum).The flora survey also found African Lovegrass (Eragrostis curvula), an environmental weed species, along the disturbed roadside verge vegetation. Although not declared a noxious weed, African Lovegrass is an exotic invasive grass species which is included in the NSW Key Threatening Process, ‘Invasion of native plant communities by exotic perennial grasses’.

Pathogens are agents that cause disease in flora and fauna and are usually living microorganisms such as bacterium, virus, or fungus. Pathogens can be spread on footwear, vehicles and machinery. Precautions are necessary to limit the spread of pathogens during construction and maintenance works. Several pathogens known from NSW have potential to impact on biodiversity as a result their movement and infection during construction of the proposal. Of these, three are listed as a key threatening process under either the EPBC Act and/or TSC Act including:

• Dieback caused by Phytophthora (Root rot; EPBC Act and TSC Act)

• Infection of frogs by amphibian chytrid fungus causing the disease chytridiomycosis (EPBC Act and TSC Act)




• Introduction and establishment of exotic Rust Fungi of the order Pucciniales on plants of the family Myrtaceae (TSC Act).

While these pathogens were not observed or tested in the study area the potential for pathogens to occur should be treated as a risk during construction. The need for this is further enforced by the close proximity to national park areas.

3.2 Fauna

3.2.1 Threatened fauna species

The dry forest habitat is dominated by Sydney Peppermint (Eucalyptus piperita), Red Bloodwood (Corymbia

gummifera) and Smooth‐barked Apple (Angophora costata). These common canopy species, in addition to a

moderately large diversity of mid‐storey plant species particularly Banksia spp, Acacia spp and

Leptospermum spp., provide shelter and food resources for a wide range of bird and arboreal mammal

species. Common aboreal mammals reported in an adjacent survey carried out to the west of the proposal

area included Common Brushtail Possum (Trichosorus vulpecula), Common Ringtail Possum (Pseudocheirus

peregrinus), and Sugar Glider (Petaurus breviceps).

The vegetated habitat to the north provides a range of food resource for birds including nectar and insects

and provides habitat for a moderate diversity of bird species. This includes an assemblage of forest species

with common species including the Bell Miner, Brown‐headed Honeyeater, Eastern Spinebill, and White‐

throated Treecreeper. Flocks of Varied Sitella (vulnerable TSC Act) were observed to the west of the proposal

area and habitat for this insectivorous species is common and widespread in the greater study area.

Koala feed tree species in the proposal area include a low density of Mountain Mahogany (Eucalyptus

notabilis) a secondary feed species and higher proportion of White Stringybark (Eucalyptus globoidea) a

supplementary feed species. There was no evidence of koalas occurring in this location. The habitat was

categorised according to the NSW Koala Recovery Plan (DECC 2009), specifically the categories provided in

Appendix 2. On this basis the habitat in the proposal area is categorised as secondary koala habitat (class C)

in that there are no primary feed tree species present and the secondary feed tree species comprise less than

30% of the tree species present.

The feed‐tree species for the threatened Glossy Black‐cockatoo (Calyptorhynchus lathami), namely Black She‐

oak (Allocasuarina littoralis) was observed outside the road reserve to the north of the proposal area. The

species was not confirmed during the survey either through direct observation or evidence of feeding (i.e.

chewed She‐oak cones). Suitable habitat was observed to be patchy in this location.

The open forest habitat to the north of the road typically has a high structural and floristic diversity with

moderate to high abundance of shelter and food resources for fauna and is potentially important for life‐

cycle activities for a diversity of species from all fauna groups. This would include, but is not limited to, Grey‐

headed Flying‐fox (Pteropus poliocephalus), Spotted‐tailed Quoll (Dasyurus maculatus), Koala (Phascolarctos

cinereus), Gang‐Gang Cockatoo (Callocephalon fimbriatum), Glossy Black‐cockatoo (Calyptorhyncus lathami),

threatened hollow‐dependent microbats and the Powerful Owl (Ninox strenua) which have been recorded in

the locality. Losses to foraging habitat for threatened fauna species would be up to 17,700 m2 (1.77 hectares)




of high and moderate condition vegetation along the southern side of Bells Line of Road within the road

reserve and on adjacent private property.

Assessments of Significance were carried for ten fauna species under the Environmental Planning and

Assessment Act 1997 (NSW) and Environment Protection and Biodiversity Conservation Act 1999 (Cth),

concluding that there is unlikely to be a significant impact on any threatened fauna.

There are no primary feed trees for Koala within the proposal area, ie Monkey Gum, however there is a

moderately high density of the secondary feed tree Grey Gum and evidence of Koalas reported on the south

side of the road. Considerable large areas of potential habitat occur to the north and south of the proposal

area which are contiguous with the areas being impacted. The clearing of habitat will occur along the edge

of very large patches and is not expected to be a significant loss of feed trees for the local population. There

may be a short term impact to the movements of the Koala during the breeding season, however the impacts

to the foraging life‐cycle is minor. There is potential for the loss of about 44 hollow‐bearing/habitat trees,

which were identified in the REF. A comparable density of hollow‐bearing trees was observed outside the

road reserve associated with adjoining remnant habitats not impacted by the project. Impacts to hollow

nesting fauna would be expected to be low. The actual number of hollow bearing trees will be identified in

the pre‐clearing report, which will be carried out prior to clearing commencing.

To mitigate the potential for increased road‐kill to native fauna wildlife road signage would be provided

warning motorists of wildlife within the road corridor.

3.2.2 Fauna habitats

Habitats and resources for fauna are abundant and widespread and it is likely that fauna populations comprise a large diversity of resident populations in addition to a range of transient or nomadic species.

Hollow trees in the study area occur in moderate abundance. The REF for the proposal identified the removal of 44 hollow‐bearing trees in the proposal area comprising small to medium hollows. The habitat trees identified in the REF are shown in Figures 3‐1 to 3‐4, along with the vegetation types.

Figure 3‐4: Biodiversity values – OT3




4. Impacts and control measures Common construction and maintenance activities which have potential to cause impacts to biodiversity if

not properly managed include:

Over clearing of vegetation;

Hygiene management including the propagation of weeds and pathogens; and

Handling fauna if discovered.

The Biodiversity Guidelines provides guidance including recommended safeguards and procedures to

managing and maintain biodiversity while undertaking these activities. These measures, which are outlined

in the following sub‐sections below are to be applied as and when any of these activities are to be

undertaken.

4.1 Risk Assessment

A risk assessment has been carried out for the project and is included in Section 7.1 of the PCEMP. This

assessment includes potential noise and vibration impacts for given work activities.

4.2 Control measures and safeguards

The below table outlines the control measures and safeguards which will be implemented to manage

potential flora and fauna impacts.

Exclusion zones may also be installed around areas which are known

to contain weeds, pathogens or pests. The type of exclusion fencing

to be installed depends on the sensitivity of what is being excluded,

level of accessibility required, size or extent of the area to be fenced,

cost, and risk of fauna being trapped, injured or isolated. Typically,

for smaller, sensitive areas high‐visibility paraweb fencing should be

installed, whereas for larger or less sensitive areas flagging tape

erected by star pickets may be suitable.

If hollow‐bearing trees are required to be felled, the following

additional measures must also be implemented:

• A suitably qualified person is to inspect the tree prior to felling

and capture/relocate residing fauna as required.

• Equipment is to be used which allows the trees to be lowered

to the ground with minimal impact, where possible.

• Once hollow‐bearing trees have been felled, they are to be

left for a period of at least 24 hours before being moved to

allow any fauna which may be residing in the tree to escape.

This may not be possible where trees are being felled over the

road or are a road safety risk. In these instances, trees will not

be able to be left in‐situ for 24 hours after being felled.

If possible, felled hollow‐bearing trees are to be placed in adjacent

areas, in preference to being mulched.

If a tree is being cleared that was not previously identified as a

habitat tree, and hollows are noticed, clearing of the tree will stop (if

safe to do so) and clearing will not recommence until an ecologist is

present.

Appendix E ‐ Weed and Pathogen Management Procedure

Introduction

Under Section 13 of the Noxious Weeds Act 1993 (NW Act), Roads and Maritime, as a public authority, is

obliged to control noxious weeds on land that it owns and prevent noxious weeds from spreading to adjoining

properties.

Vegetation along the road corridor edge was found to contain a number of weeds declared as a noxious weed

for the Hawkesbury LGA, with moderate to high infestations of the following species noted:

Blackberry (Rubus fruticosus)

Crofton Weed (Ageratina adenophora)

Montbretia (Crocosmia x crocosmiiflora)

Montipellier Broom (Genista monspessulana)

Privet (Broad‐leaf) (Ligustrum lucidum)

Privet (Narrow‐leaf/Chinese) (Ligustrum sinense)

St John’s Wort (Hypericum perforatum)

The flora survey also found African Lovegrass (Eragrostis curvula), an environmental weed species, along the

disturbed roadside verge vegetation. Although not declared a noxious weed, African Lovegrass is an exotic

invasive grass species which is included in the NSW Key Threatening Process, ‘Invasion of native plant

communities by exotic perennial grasses’.

Weed Identification

Weeds on the site were surveyed by an ecologist as part of the Flora and Fauna assessment. Attached are

photos to assist the site team to identify any further infestations in areas not already identified.

Relevant documents

Downer safety alert – weed handling and removal.

Protocol

Weeds The following measures are to be implemented during construction and maintenance works to manage

potential biodiversity impacts arising from weeds:

As part of the pre‐clearing survey, the ecologist will identify weed infestations, and ensure they are

mapped or clearly identified on the ground, so as they are easily identifiable by the clearing and

earthworks contractor.

Where there are specific weed removal requirements identified, training will be provided to the

clearing contractor to ensure that the removal of those weeds are managed to minimise the spread

of weeds.

All plant and equipment is to be cleaned to remove any debris and materials prior to entering site.

This is necessary to minimise the risk of weeds and pathogens being transferred to the site.

All equipment used to handle weeds is to be cleaned after use.



Securely cover loads of weed‐infested materials, to ensure that it is not inadvertently dispersed to

other areas.

Dispose of all weed‐contaminated soils at appropriately licenced waste management facilities.

Separate weeds from native vegetation, where native vegetation is to be used for mulch. Do not use

weeds for mulch.

Manage localised weed issues through the application of herbicides in accordance with the Pesticides

Act 1999 (NSW), and ensure the application of any pesticide is in accordance with the

DownerMouchel SMC EMP.

Pathogens Pathogens are agents that cause disease in flora and fauna and are usually living microorganisms such as

bacterium, virus, or fungus. Pathogens can be spread on footwear, vehicles and machinery. Precautions are

necessary to limit the spread of pathogens during construction and maintenance works. Although

management measures are specific to the type of pathogen, the following general measures to limit the

spread of pathogens are to be considered where practical and feasible:

Minimise work during excessively wet or muddy conditions.

Stockpile mulch, topsoil and fill materials separately to avoid potential contamination and spread.

Avoid using site run‐off water for dust suppression.

A risk assessment will be undertaken for Phytopthora cinnamomi, exotic Rust Fungi and Chytrid fungus prior

to the commencement of work, and specific mitigation measures and procedures developed if the risk is

high. If procedures or mitigation measures are required, all personnel will be trained in the procedure, to

minimise any potential spread of pathogens.

Appendix F – Fauna Management Procedure

If fauna is encountered during works, it is important that the following management procedure is followed:

1. Stop works within the vicinity of the animal;

2. If the animal is injured, the Site Supervisor is to contact a pre‐arranged animal rescue agency/wildlife

care group/vet. The contact details will vary throughout the network.

3. If the animal is unharmed and the works can be postponed, leave the animal to vacate the site on its

own accord. If works are unable to be delayed, the Site Supervisor is to contact the licensed fauna

ecologist/wildlife carer to safely relocate the animal.

4. Works can re‐commence once the animal has been collected or relocated.

5. The Site supervisor is to keep a record of all fauna rescued and relocated during the works and passed

on to the Environmental Manager to record in a register.

6. If animals are found dead on the road, record the death in a register. Review the location where the

roadkill was found, and investigate installing mitigation measures to minimise the risk of road kill in

that location to re‐occur.

Dear Cameron,

Re: Pre-Clearance Advice – Bells Line of Road Overtaking Lane Site 3 – Tadrosse Lane

to Pup Road Project no. 22237

The following correspondence provides a summary of the methods and results of the pre-clearance survey

of vegetation designated for removal or trimming along a 1.2 kilometre stretch of Bells Line of Road

between Tadrosse Lane and Pup Road (the study area) (Appendix 1: Figure 1). The study area equates to a

total area of 3.1 hectares, inclusive of 1.76 hectares of native vegetation, 0.15 hectares of exotic trees and

shrubs and 1.19 of hardstand.

These works are planned to enable the construction of a new westbound overtaking lane as part of the

Bells Line of Road Overtaking Lane Site 3 (OT3) – Tadrosse Lane to Pup Road Project (the Project). In

pursuance of the Project, Biosis has been engaged by Hutchison Weller on behalf of DownerMouchel to

undertake a pre-clearance survey and supervise clearing works.

This assessment has been undertaken in accordance with the NSW Roads and Maritime Services (Roads

and Maritime) Bells Line of Road – overtaking lane Site 3 Tadrosse Lane to Pup Road Review of Environmental

Factors (RMS 2015), specifically to meet requirements within section 6.1.4 – Biodiversity impacts.

Furthermore, this assessment is to comply with the Roads and Maritime Biodiversity Guidelines (RTA 2011)

including the requirements of Guide 1, 2, 4, 5, 6, 7 and 9.

This assessment also complies with the following items from the Stewardship Maintenance Contract – Sydney

West Zone- Bells Line of Road, Overtaking Lane Site 3 CEMP (DownerMouchel 2016):

FF07: Habitat trees (i.e. hollow-bearing trees) will be identified during pre-clearing assessments and will be clearly

marked on-site by an ecologist.

FF08: All habitat requiring protection identified in the environmental assessments or approvals within the clearing

limits is to be identified and marked on-site by a suitable qualified person

This letter advice has been prepared to address these specifications.

The findings of the pre-clearance survey have been prepared by Biosis (qualified and experienced

ecologists), in accordance with EPBC Conditional Approval (2014/7346) (Department of the Environment

[DoE] 3 November 2015) documentation for the Project.


Methodology

The pre-clearance survey of existing vegetation to be removed or trimmed along the interface of Bells Line

of Road between Tadrosse Lane and Pup Road was undertaken on 19 April 2016 by Nicola Trulock

(Botanist) of Biosis accompanied by Cameron Weller (Environmental Scientist) of Hutchison Weller.

The pre-clearance survey consisted of the following:

Verification/identification of vegetation within the study area.

Verification/identification of weeds or weed infestations and recommendations for management.

Identification and marking of all individual habitat trees within the study area to be removed.

Check for presence of fauna habitat including tree hollows, nests, bushrock and large woody debris.

Identification and marking of any unsound trees within the study area and determination of

appropriate management.

Findings

Confirmation of biodiversity features

1.40 hectares of native vegetation present throughout the majority of OT3 is consistent with the NSW TSC

Act listed endangered ecological community (EEC), Blue Mountains Shale Cap Forest in the Sydney Basin

Bioregion (Blue Mountains Shale Cap Forest) and the EPBC Act listed critically endangered ecological

community (CEEC) Turpentine-Ironbark Forest of the Sydney Basin Bioregion (Turpentine-Ironbark Forest CEEC)

(Appendix 1: Figure 1). The Sydney Turpentine-Ironbark CEEC is in moderate condition with a canopy layer

predominantly composed of native trees consisting of Turpentine Syncarpia glomulifera, Sydney Red Gum

Angophora costata, Blue Mountains Mahogany Eucalyptus notabilis, Sydney Peppermint E. piperita, Grey Gum

E. punctata and Red Bloodwood Corymbia gummifera. The midstorey and understorey layers are dominated

by native species representative of the Sydney Turpentine-Ironbark Forest EEC such as Pultenaea scabra,

Prickly Shaggy Pea Podolobium ilicifolium, Elderberry Panax Polyscias sambucifolia, Spiny-headed Mat-rush

Lomandra longifolia, Blue Flax-lily Dianella Caerulea and. Maidenhair Fern Adiantum aethiopicum and Sickle

Fern Pellaea falcata.

The vegetation community present throughout the eastern end of OT3 is consistent with the Blue

Mountains Shale Cap Forest EEC only (ie. not conforming to EPBC Act listed Sydney Turpentine-Ironbark

CEEC), and amounts to a total area of 0.36 hectares (Appendix 1: Figure 1). The Blue Mountains Shale Cap

Forest EEC comprises of a canopy layer composed of native tree species such as White Stringybark E.

globoidea, Sydney Peppermint and Blue Mountains Mahogany and Turpentine. The midstorey and

understorey layers are dominated by native species representative of the Sydney Turpentine-Ironbark

Forest EEC such as White Dogwood Ozothamnus diosmifolium, Parramatta Wattle Acacia parramattensis and

Elderberry Panax, Spiny-headed Mat-rush, Dianella Caerulea, Pomax Pomax umbellata and Wiry Panic.

The vegetation community present at the far eastern end of OT3 is consistent with Exotic Trees and Shrubs,

amounting to a total area of 0.15 hectares (Appendix 1: Figure 1). The Exotic Trees and Shrubs community

consists of a canopy layer composed of Radiata Pine Pinus radiata over a shrub layer of Camellia Camellia sp.

overtopping an understorey predominantly comprised of exotic grasses and herbs.

A list of flora recorded throughout the study area can be found in Appendix 4: Table A.3.

Threatened species


No threatened flora or fauna species were recorded within the study area during the pre-clearance survey.

A list of fauna recorded as utilising the site during the field assessment can be found in Appendix 5: Table

A.4.

Habitat tree identification

Hollow-bearing tree identification was conducted according to RMS Biodiversity Guidelines with stags

(standing dead trees) included in the count. A total of 48 hollow-bearing trees were identified within the

study area, 42 of which are within the clearing limits along OT3 (Appendix 1: Figure 1). The remaining six

hollow-bearing trees were rooted outside of the clearing limits but bore overhanging branches which may

require trimming as part of the Project (see Appendix 3: Table A.2).

It should be noted that the observer's view from the ground was partially obscured by a number of large

canopy trees at the western end of the study area. This may have limited the identification of all hollows in

this area and it is possible hollows exist that have not been recorded.

Habitat features

Eight logs between 4 and 15 metres in length and 20 to 60 centimetres in diameter were recorded within

the western end of OT3, four of which were hollow (Appendix 1: Figure 1; Appendix 3: Table A.1). No

bushrock was recorded within the study area.

Noxious weeds

Four noxious weed species listed in the Hawkesbury City Council Local Government Area were identified

within the study area, these being Blackberry Rubus fruticosus, Broad-leaved Privet Ligustrum lucidum,

Montpellier Broom Genista monspessulana and Small-leaved Privet Ligustrum sinense (Appendix 1: Figure 1).

These noxious weed species will require management to suppress the population and prevent further

spread. Blackberry, Broad-leaved Privet and Small–leaved Privet are already known within the project area

and are covered under the current REF, whereas Montpellier Broom is addition to the project area and is

covered in the Project CEMP only. Information about this noxious weed is outlined in Table 1.

Table 1 Additional noxious weeds recorded within the study area

Scientific Name Common Name Class Legal Requirements

Genista monspessulana Montpellier Broom 3 The plant must be fully and continuously and

destroyed and the plant must not be sold,

propagated or knowingly distributed.

Suitable fauna relocation sites

Any fauna found within the study area during vegetation clearing works will be relocated in the adjacent

Blue Mountains World Heritage Area which will allow all relocated fauna to remain within their natural

home range. Any injured fauna encountered within the study area is to be taken to the closest veterinary

hospital for examination and then released to a WIRES Wildlife Carer for fostering and eventual release:

Kurrajong Veterinary Clinic (16 Old Bells Line of Road, Kurrajong, Phone: (02) 5473 1216).

Legislative implications

A total of 1.40 hectares of vegetation assessed as both Sydney Turpentine-Ironbark Forest CEEC (EPBC Act)

and as Blue Mountains Shale Cap Forest under the NSW TSC Act is to be removed subject to EPBC

Conditional Approval (2014/7346) DoE 3 November 2015 and the Project Review of Environmental Factors


(REF) approved under Part 5 of the Environmental Planning and Assessment Act 1979 (EP & A Act) (Roads

and Maritime 2015)

Furthermore, a total of 0.36 hectares of Blue Mountains Shale Cap Forest meeting NSW TSC Act criteria and

0.15 hectares of Exotic Trees and Shrubs are expected to be removed in furtherance of the Project. The

removal of this vegetation has been assessed and approved under the Project REF (Roads and Maritime

2015).

Recommendations

Based on the above findings, and the nature of works required (removal of 42 trees within the clearing

limits and trimming of six trees overhanging the clearing limits), the following recommendations are

provided:

Hollow-bearing tree removal is to be conducted under the supervision of an ecologist by qualified

arborists using the two stage process outlined in the RMS Biodiversity Guidelines (RTA 2011). All

non-habitat vegetation surrounding the marked hollow-bearing trees is to be removed, leaving the

hollow-bearing trees to remain standing for a minimum of 24 hours to allow fauna to vacate

remaining habitat. Once the minimum time period has lapsed, fell the habitat trees carefully

ensuring they are lowered with minimal impact to the ground. All felled habitat trees are to be

inspected by an ecologist prior to mulching.

Branch trimming is to be undertaken by accredited and experienced arborists using cleaned and

sterilised equipment to prevent the transmission of plant pathogens.

All green waste resulting from branch trimming is to be mulched and disposed of accordingly.

Four noxious weeds within the Hawkesbury City Council LGA, identified as Blackberry, Broad-leaved

Privet, Small-leaved Privet and Montpellier Broom, were recorded within the study area (Table 1).

Any green waste resulting from vegetation clearance in the vicinity of these noxious weeds is to be

disposed of at the nearest registered green waste disposal facility.

All vegetation to be retained is to be fenced off with accompanying signage demarcating it as an

environmental exclusion zone. All staff and contractors associated with the Project are to be made

aware of the location and extent of environmental exclusion zones during site induction and tool-

box talks.

The eight logs forming coarse woody debris are to be carefully lifted from within the clearing limits

by crane and are to placed within an adjacent environmental exclusion zones.

All fauna found within the study area during the clearing process is to be released into the nearby

Blue Mountains World Heritage Area. All injured fauna is to be taken to Kurrajong Veterinary Clinic

for examination and then handed over to a WIRES fauna carer for fostering and release.

Conclusion

This pre-clearance survey has fulfilled DownerMouchel's obligation to engage an Ecologist to undertake a

pre-clearance survey to comply with EPBC Conditional Approval (2014/7346) (DoE 3 November 2015), the

NSW Roads and Maritime Bells Line of Road – overtaking lane Site 3 Tadrosse Lane to Pup Road Review of

Environmental Factors (RMS 2015), Roads and Maritime Biodiversity Guidelines (RTA 2011) and Stewardship

Maintenance Contract – Sydney West Zone- Bells Line of Road, Overtaking Lane Site 3 CEMP (DownerMouchel

2016). Upon completion of the pre-clearance survey it has been determined that the above mentioned

recommendations are to be applied regarding the felling of 42 hollow-bearing trees, trimming of six native


trees, relocation of coarse woody debris, fauna relocation areas, correct disposal of green waste and use of

suitably qualified arborists.

1. Introduction This Construction Noise and Vibration Management Plan (CNVMP) forms part of the Project Construction

Environmental Management Plan (PCEMP) for the construction of Overtaking Lane Site 3 (OT3) on the Bells

Line of Road between Tadrosse Lane and Pup Road (the Project) being delivered by DownerMouchel (DM) as

part of the Stewardship Maintenance Contract with the Roads and Maritime Services (Roads and Maritime).

The purpose of this CNVMP is to describe how potential impacts associated with noise and vibration shall be

managed during pre‐construction, construction, and post‐construction activities associated with the project.

Works shall be implemented in accordance with the management measures and mitigation strategies set out

within this Sub‐Plan.

This Sub‐Plan complies with and supplements the OT3 CEMP, and has been developed in accordance with

Interim Construction Noise Guidelines, 2009 (ICNG).

The processes defined within this Sub‐Plan shall be implemented by all parties either directly employed by

DM or subcontracted and will apply to all activities listed in the SMC.

For information regarding objectives and targets, aspects and impacts, legislative requirements, DM training

and awareness, communications, monitoring, corrective action, incident management and document

control; and how they are applied to the Project, refer to the DownerMouchel SMC EMP.

2. Objectives The key objective of the CNVMP is to ensure that impacts to the local community and the built environment

from noise and vibration are minimised. Specific objectives include:

Identifying sensitive receivers and ensuring appropriate environmental controls and procedures are

3. Existing environment

3.1 Sensitive receivers

The project is located in an area consisting primarily rural residences and agricultural enterprises. A total of

seventeen sensitive residential noise receivers have been identified within the proposal area (as identified

by aerial photography and site visits), and are shown in Figure 3‐1. The closest is located about 30 metres

from the existing road edge.

3.2 Ambient noise

To characterise the existing noise environment for the proposal and establish the background noise levels

for construction noise management within the study area, the residential property at 2175 Bells Line of Road

was chosen and background noise monitoring undertaken over a 24‐hour period.

The daily environmental noise measurement profile for the monitoring location is shown in Table 3‐1. The

rating background level (RBL) in the table is the median of the background noise levels for the site and is used

in determining the construction noise management level (NML). The LAmax and LAeq levels provide additional

information on the existing noise environment.

Table 3‐1 Summary of monitoring results – environmental noise descriptors (dB(A))

* Where the RBL is less than 30dB(A), the RNP sets the criteria as 30 dB(A) for assessment purposes

Existing noise levels along the proposal are heavily influenced by road traffic noise and fauna influences such

as bird song. Background noise levels reduce during the night reflecting the intermittent traffic flows at this

time. However, evening and night time traffic movements have a high percentage of heavy vehicles, which

tends to maintain LAeq noise levels during these periods.

4. Noise and vibration criteria for NSW

4.1 Construction noise criteria

Construction noise management levels are determined by the NSW ‘Interim Construction Noise Guideline’

(ICNG, DECC 2009).

In general these criteria provide that, for residential receivers, the construction noise should not exceed the

background by more than 10 dB(A) during standard hours, and by more than 5 dB(A) out of hours (that is, for

night‐time works). If these levels are exceeded then receivers are considered noise affected and all

reasonable and feasible noise measures should be used to minimise noise. 75dB(A) is the level at which

receivers are considered highly noise affected.

4.1.1 Adopted project NMLs

Construction NMLs are based on the background noise level data collected during the noise monitoring. Due

to the nature of the noise environment and the varying distances from the existing road, all receivers within

the proposal area have been assigned the same background noise levels for the assessment of construction

noise impacts. This approach of grouping receivers into a single noise catchment area is a conservative

estimate of noise levels. The NMLs for the proposal are presented in Table 4‐1.

4.2 Construction vibration

4.2.1 Human comfort

Vibration from construction activities must comply with the EPA policy document Assessing vibration: A

technical Guideline (DECC 2006), which may be classified as one of the following types:

Continuous – where vibration occurs uninterrupted and can include sources such as machinery and

constant road traffic.

Impulsive – where vibration occurs over a short duration (typically less than 2 seconds) and occurs

less than three times during the assessment period, which is not defined. This may include activities

such as occasional dropping of heavy equipment or loading / unloading activities.

Intermittent – occurs where continuous vibration activities are regularly interrupted, or where

impulsive activities recur. This may include activities such as rock hammering, drilling, pile driving

and heavy vehicle or train passbys.




The proposed works will fall predominantly in the intermittent vibration category. Intermittent vibration

impacts may be present when continuous vibration sources operate sporadically throughout the assessment

period. This type of impact is assessed using vibration dose values (VDVs). Preferred and maximum VDVs for

residential receivers are summarised in Table 4‐2 Acceptable vibration dose values for intermittent

vibration (ms‐1.75).

4.2.2 Structural damage

The Australian Standard AS2187.2‐2006 Explosives – Storage, Transport and Use provides guidance for the

assessment of structural damage to buildings caused by vibration. This section of the standard is based on

the British Standard 7385: Part 2 Evaluation and measurement of vibration in buildings and is used as a guide

to assess the likelihood of building damage from ground vibration from piling, compaction, construction

equipment and road and rail traffic. The standard recommends levels at which ‘cosmetic’, ‘minor’ and ‘major’

categories of damage might occur based on the type of structure affected.

The standard uses the component Peak Particle Velocity (PPV) parameter to quantify vibration and specifies

damage criteria for frequencies within the 4 Hz to 250 Hz range for buildings. The criteria levels identified in

the standard are outlined in Table 4‐3.

Table 4‐3 BS 7385 Structural damage criteria

Group Type of structure Peak particle velocity (PPV), mm/s

4Hz to

15Hz

15Hz to

40Hz

40Hz and

above

1 Reinforced or framed structures Industrial and heavy commercial buildings 50

2 Un‐reinforced or light framed structures Residential or light commercial

type buildings 15 to 20 20 to 50 50

The levels for structural damage outlined in the standard refer to non‐continuous vibration sources and are

considered ‘safe limits’ up to which no damage due to vibration effects are expected to occur for the various

building types. Where vibration is continuous, these levels may be reduced by up to 50 per cent and

additional assessment against the standard would be necessary.

Where heritage structures are impacted, the German DIN Standard 4150‐3 Structural Vibration, Part 3:

Effects of Vibration on Structures can be used for guidance. There are no historical archaeological structures

likely to be impacted by the project (REF).




5. Impacts and control measures Common construction and maintenance activities which have potential to cause impacts to noise and

vibration if not properly managed include:

Site establishment;

Earthworks;

Road preparation ie asphalt milling;

Laying new asphalt;

Finishing works and landscaping.

Further to this, works which occur outside of standard construction hours also pose potential impacts to local

receivers.

5.1 Construction phases

The proposed activities for the overtaking lane upgrade include road widening, re‐grading sections of the

alignment, intersection upgrades, asphalting, and line marking. These activities would use a variety of

equipment throughout the duration of the works of about 6 months. Typical activities have been tabulated

in Table 5‐1 for individual construction phases, showing the expected duration of each phase.

5.2 Work hours

The majority of work will be carried out during normal hours; however the proposal would require all work

to be completed within the existing road boundary so would occur concurrently with normal road use. Some

activities may therefore be scheduled during the non‐peak periods and possibly outside of standard

construction hours. An assessment of out of hours noise impacts for the evening and night time has been

included in the consideration of noise impacts from construction activities.

Generally works outside standard hours are acceptable to the community where noise levels are below the

respective background level. However the noise of some construction activities is likely to be above the

project NMLs during the night time period and cannot be easily mitigated.

Typical activities for a road upgrade that may be required outside standard construction hours would include:

Delivery of plant and large construction equipment;

Emergency work;

Utility adjustments;

Major traffic changes;

Road tie‐in works;

Other works as required.

These activities have been assessed in accordance with the ICNG for out of hours works and are compared

to sensitive receiver NMLs for the evening and night time periods in Section 5.3.1.

5.3 Construction noise and vibration impacts

5.3.1 Construction noise

To predict the potential impacts from construction noise at a sensitive receiver location, the construction

activities were modelled. The prediction considers the closest point where works would be undertaken to a

receiver and therefore represent a worst case scenario. Predicted noise levels were then compared to the

proposal NMLs.

The predicted noise level for each receiver is presented in Table 5‐2. Table 5‐2 indicates the potential for

exceedance of the noise goals at each of the receiver locations during each phase of the works.

Construction noise mitigation measures would need to be applied for these locations, as discussed in Section

5.5.

Note: Bold text indicates values exceeding the highly noise affected level.




Table 5‐3 summarises predicted noise levels from works likely to occur outside standard hours and includes

comparison with the sleep disturbance screening criterion.

Table 5‐3 shows that the predicted levels of noise generated from works undertaken outside of standard

construction hours would be in excess of the night time NML. The actual impact would depend on the location

of the works within the corridor and the proximity to the nearest receiver. Sleep disturbance criteria are

expected to be exceeded for all receivers during the asphalting, utility adjustment and line marking works,

due to the low background noise levels at night.

Management measures to reduce potential out‐of‐hours construction noise impacts are discussed further in

Section 5.5.

5.3.2 Construction vibration

The REF determined that vibration estimations would:

Have a potential adverse impacts on human comfort within 30 metres of the vibration‐generating

activity;

Vibration would have potential adverse impacts on structures within 20 metres of the vibration‐

generating activity.

For the receiver closest to the proposed earthworks and pavement laying construction (within 20 metres),

it is that possible that vibration levels would be perceived to be high on occasion.

5.4 Risk Assessment

A risk assessment has been carried out for the project and is included in Section 7.1 of the PCEMP. This

assessment includes potential noise and vibration impacts for given work activities.

5.5 Control measures and safeguards

The below table outlines the control measures and safeguards which will be implemented to manage

potential noise and vibration impacts.

The following vibration monitoring will be undertaken:

Vibration monitoring will be carried out in response to complaints, exceedances, or for the

purpose of refining construction methods or techniques to minimise vibrations.

Where vibration is found to exceed safe levels, reduction in impacts will be achieved by changing work

methods and/or equipment, or through the provision of building protection measures where possible. In the

event a complaint relating to property damage is received, an inspection of the property would be

undertaken and an interim building condition survey prepared.

Vibration monitoring will be carried out in accordance with:

For structural damage vibration – German Standard DIN 4150 and BS 7385: Part 2 – 1993.

For human exposure to vibration – the evaluation criteria presented in the Environmental Noise
