GHD | Report for Lockhart Shire Council - Government Dam levee, 2315983 | 1

1. Introduction

1.1 The proposal

Lockhart Shire Council (Council) is proposing to construct a levee bank at Government Dam as part of the flood mitigation works for Lockhart. The proposal also includes constructing a channel and berm east of Lockhart – Collingullie Road (see Figure 1-1). The proposal is required to protect residential properties to the south of Brookong Creek flooding, following two severe flood events in October 2010 and March 2012.

Following these flood events, Council engaged the services of WMAwater to undertake studies leading to the development of a Floodplain Risk Management Plan (FRMP) for Lockhart in 2014 (WMAwater 2014a). Detailed designs for flood mitigation works were subsequently completed by GHD (2016) for a number of mitigation options.

The proposal is for the construction of one of these options – the construction of a levee bank at Government Dam.

Council has engaged GHD to prepare a Review of Environmental Factors (REF) to assess the potential environmental impacts of the proposal.

For the purposes of this REF, the following definitions are used:

The ‘proposal’ or ‘proposal site’ - refers to the area required for the construction of the proposal, including construction activities and construction vehicle access. It includes the construction footprint, site compound, stockpile sites and any areas that would be disturbed (see Figure 1-1)

The ‘study area’ refers to the area of impact and any additional areas, which are likely to be affected by the proposal, either directly or indirectly. Generally, the study area includes the area up to 500 metres from the proposal site.

The ‘locality’ refers to the area within a 10 kilometre radius of the proposal.

1.2 Purpose of this report

This review of environmental factors (REF) has been prepared by GHD on behalf of Council to assess the potential environmental impacts of the proposal. For the purposes of the proposal, Council is the proponent and determining authority under Part 5 of the Environmental Planning and Assessment Act 1979 (EP&A Act).

The purpose of the REF is to describe the proposal, to document the likely impacts of the proposal on the environment, and to detail mitigation measures to be implemented as part of the proposal.

The proposal has been assessed in the context of clause 228 of the Environmental Planning and Assessment Regulation 2000, the Threatened Species Conservation Act 1995 (TSC Act) and the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). In doing so, the REF helps to fulfil the requirements of section 111 of the EP&A Act that Council examine and take into account to the fullest extent possible, all matters affecting or likely to affect the environment by reason of the activity.

The findings of the REF would be considered when assessing:

Whether the proposal is likely to have a significant impact on the environment and therefore the necessity for an Environmental Impact Statement to be prepared and


approval to be sought from the Minister for Planning and Environment under Part 5.1 of the EP&A Act.

The significance of any impact on threatened species as defined by the TSC Act, in section 5A of the EP&A Act and therefore the requirement for a Species Impact Statement.

The potential for the proposal to significantly impact on a matter of national environmental significance or Commonwealth land and the need to make a referral to the Australian Government Department of the Environment and Energy (DotEE) for a decision by the Commonwealth Minister for the Environment on whether assessment and approval is required under the EPBC Act.

The proposal


2. Needs and options considered

2.1 Need for the proposal

Lockhart experiences regular flooding from Brookong Creek and also from major overland flow. The March 2012 and October 2010 flood events surpassed all previous events in terms of both magnitude and damage. The March 2012 event is the largest flood event in Lockhart’s history, reaching 2.1 metres on the Green Street causeway gauge. About 67 houses and 31 commercial/public sector building were flooded above floor level. The flood was caused by flooding from Brookong Creek and overland flows.

The objective of the proposal is to protect residential properties to the south of Brookong Creek from flooding.

2.2 Alternatives and options considered

A number of flood modification options were put forward to the community and included as part of the FRMP (WMAwater 2014a), including:

1. Modification of Lockhart Government Dam

2. Levee to the rear of Galore Street

3. Increased capacity of the Oaklands Railway Bridge and Reid Street Bridge

4. Diversion of Milbrulong flow south of Lockhart by increasing culvert capacity

5. Regular removal of debris from Brookong Creek to reduce blockage

6. Levee behind properties on Urana Street to stop Brookong Creek flooding

7. Creation of a channel along Brookong Street.

Options 1,4 and 7 were investigated further with advanced concept designs completed by GHD in 2016. These options included the following:

Option G3 - Extension and upgrade of Government Dam. This is essentially a levee bank

Option C2 – Construction of a new drain and culvert at Lockhart – Collingullie Road on the north eastern fringe of Lockhart

Option M1 – Construction of a diversion channel on the east side of Lockhart, including upgrade of cross drainage structures such as culverts.

Option G3 and C2 were combined and together became known as the Government Dam Levee option This is the preferred option. This option includes the following features:

Construction of a levee along Government Dam

Installation of additional pipe culverts under Lockhart – Collingullie Road

Construction of a channel and berm on the eastern side of Lockhart – Collingullie Road.

The do nothing option would involve leaving the Government Dam area as is with no installation of flood mitigation measures. This option would not improve the flooding characteristics of the area south of Brookong Creek during a flood event and therefore no protection would be provided for residential properties to the south. This option would not meet the objectives of the proposal and is therefore not the preferred option.


2.3 Preferred option

The preferred option is the construction of the Government Dam levee, due to the better benefit/cost ratio as well as the higher level of flood mitigation. In flood events, the levee will provide protection to the residential properties on the south side of the levee.


3. Description of the proposal

3.1 The proposal

Council proposes to construct a formal levee bank at Government Dam, in Lockhart, to protect properties to the south of Brookong Creek from flooding. The proposal includes construction of a levee along Government Dam, installation of additional pipe culverts under Lockhart – Collingullie Road to increase their water carrying capacity, and construction of a channel and berm on the east side of Lockhart – Collingullie Road (see Figure 1-1 and Appendix F).

A temporary site compound and stockpile site would be established within the proposed levee site.

It is anticipated that construction of the proposal would take about three months.

3.2 Design

3.2.1 Design criteria

The design of the proposal has used the following design criteria:

860 metre embankment length

Typical embankment height of two metres

Embankment level of 157.7 metres Australian Height Datum (AHD) (west end) to 158.0 metres AHD (east end) (0.5 metre freeboard above the 100 year Average Recurrence Interval (ARI) flood level)

Embankment top width of two metres

Embankment slopes at four horizontal to one vertical for both wet and dry sides

One percent Annual Exceedance Probability (AEP) flood level of 157.2 metres AHD

35 metre wide spillway at 155.5 metre AHD

Spillway discharges from the north-west corner of the basin towards Brookong Creek.

3.2.2 Levee at Government Dam, west of Lockhart - Collingullie Road

The detailed design has been prepared consistent with the WMAwater concept design proposal and the approved GHD advanced concept design (see Appendix F). This is based on a design which achieves a levee crest with 500 millimetres of freeboard above the 100 year ARI flood level.

In flood events, the levee will provide protection to the residential properties on the south side of the levee. Outflows will initially be confined to the spillway within a flood level range of 155.5 metres AHD (spillway crest) to 156.0 metres AHD (natural overflow threshold to the north of the spillway).

Design flood levels at the spillway end of the levee are:

5 year ARI flood level 156.5 metres AHD

100 year ARI flood level 157.2 metres AHD.

The spillway crest level is set close to natural surface at the same level as the existing informal spillway. The spillway will be of earthen construction, owing to the low velocities and flow across the spillway.


A low flow pipe would be positioned at the western end of the levee to allow outflow into Brookong Creek.

3.2.3 Channel and berm in TSR, east of Lockhart – Collingullie Road

The work on the eastern side of Lockhart – Collingullie Road (see Appendix F), including the culvert work under the road comprises the following:

Installation of two cell precast 900 millimetre diameter pipe culverts under Lockhart – Collingullie Road to supplement the existing 1200 millimetre pipe

A channel and berm on the upstream (east) side of the road.

The channel and berm are designed to direct water from the east side of Lockhart – Collingullie Road, through the culvert under the road, and behind the levee to avoid water travelling through the town. The maximum height of the berm is about 970 millimetres.

The alignment of the proposal on the east side of Lockhart – Collingullie Road has been altered from the concept design to avoid impacts on trees and a threatened ecological community; however, the design of the proposal would remain the same as the existing concept design (see Appendix F).


3.3 Construction activities

3.3.1 Work methodology

Pre-construction activities

Construction would be undertaken by Council in accordance with a construction environmental management plan (CEMP).

Pre-construction activities would include:

Site establishment (fencing, site compound and stockpile sites)

Establish work site boundaries

Installation of environmental control measures and erosion and sediment controls, including clean and dirty water diversions

Set up stockpile sites for storing materials

Establishment of site compound including site office and toilet facilities

Establishment of turning area for vehicles, plant and equipment

Set up temporary traffic controls.

Construction activities

Levee construction activities would include:

Remove soil, trees, vegetable matter and other debris from the proposed levee footprint

Undertake cut and fill earthworks operations to construct levee to new levels. Earthworks will involve placement of some imported fill material

Install gabion mattress over spillway area.

Locate and adjust a 25 millimetre water service as necessary

Install the low flow pipe (under the levee – see Appendix F) and control pit structure. This will include excavation of fill around and above pipes, construction with concrete, placement of bedding material, installation of precast pipe culverts, installation of precast pit and valve, and installation of concrete headwalls with gabion outlet protection

Use and disposal of excavated material, spoil and unsuitable material including the following:

– Excavated material would be used for levee construction, with additional material imported from local borrow sites

– Unsuitable materials that cannot be re-used would be transported to a licensed disposal facility.

Culvert drainage construction activities would include:

Remove soil, vegetable matter and other debris from the vicinity of the pipes

Construct two new pipe culverts adjacent to the existing pipe culvert. This may include excavation of road material adjacent to the existing pipe, placement of bedding material, installation of precast pipes, placement and compaction of gravel, and installation of concrete headwalls and outlet protection gabions

Regrade culvert inlet and outlet channels within the road reserve to permit free drainage where required


Replacing existing line-marking, raised pavement markers, guideposts and signage.

Channel and berm construction activities would include:

Remove soil, vegetable matter and other debris from the vicinity of the channel footprint

Potential relocation of Telstra underground cabling where identified in the drawings and on site as necessary.

Undertake earthworks to shape the channel and berm, including cut and fill operations and compaction of the finished surfaces

Undertake topsoil and seeding of the channel and berm

Site clean-up and rehabilitation, including:

– Removing excess material from stockpile sites

– Removing temporary stockpile sites

– Revegetating disturbed areas

– Removing temporary erosion and sedimentation controls, following stabilisation of disturbed areas

– Removing temporary traffic controls

– Reinstate fences and gates as appropriate.

Construction hours

It is anticipated that the proposal would typically be completed within the following hours:

Monday to Friday: 7am to 6pm.

Saturday: 7am to 1pm.

Sunday and Public Holidays: no work.

Plant and equipment

Plant and equipment needed for the proposal would include:

Water carts Scraper

Pad foot roller Backhoe

Steel drum roller Grader

Excavator Bitumen sprayer

Loader Aggregate spreader

Trucks Whacker plate

3.3.2 Earthworks

Earthworks will include:

About 5,642 cubic metres of cut for construction at Government Dam levee

About 6,729 cubic metres of fill for construction at Government Dam levee

About 1,249 cubic metres of fill from Treasure Street spoil site for construction at Government Dam levee

About 48 cubic metres of cut for channel and berm construction in TSR


About 1,106 cubic metres of fill for channel and berm construction in TSR

About 1,065 cubic metres of fill from Treasure Street spoil site for channel and berm construction in TSR

The majority of fill required for the proposal would be gained on site from Government Dam (see Appendix F). The balance of fill would be gained from an existing build-up of spoil located between Treasure Street and Brookong Creek on the west side of Lockhart. It is proposed that this would be removed to natural ground level as part of the proposal. About 2,314 cubic metres of spoil from the site would be used as fill for construction of the levee and channel and berm (see Figure 3-1 - orange shaded area).


Figure 3-1: Treasure Street spoil site


3.3.3 Materials

The following materials would be required for the construction of the proposal:

320 square metres of gabion mattress for protection downstream of spillway

320 square metres of geofabric for under gabions

66 metres of 450 millimetre diameter low flow pipe

29 metres of 900 millimetre diameter pipe for culvert plus various associated materials

Bedding sand, road base and seal.

Water may be required during construction to achieve required earthworks moisture content, and to supress dust. If required, water would be sources from water supply mains in the area.

3.3.4 Construction traffic management and access

Vehicle movements

The proposal would generate a number of heavy vehicle movements through the transport of machinery, fuel, general provisions and materials. The majority of vehicle movements would be for the transport of spoil form Treasure Street to the Government Dam site.

The number of heavy vehicle movements required to transport spoil from Treasure Street to the proposal site would be about 100 over the three month construction period. Two trucks would cart about 50 loads of spoil each over the duration of the construction period.

Light vehicles would be required to transport staff to and from the proposal site. Light vehicles would also be used in various roles on site.

Traffic management

Traffic controls would be put in place for works in the vicinity of Lockhart – Collingullie Road, including, levee construction in the road reserve, table drain work and the installation of the additional culverts. Traffic controls would be in accordance with the Australian Standard 1742.3-2002: Manual of Uniform Traffic Control Devices and the NSW Roads and Maritime Services ‘QA Specification G10 Traffic Control at Worksites’. For culvert works, traffic may be restricted to one lane, or alternatively redirected onto a side track in the road reserve on the southern side of the road. The proposal would be unlikely to cause any significant disruption to traffic.

Construction access management

Construction access to the proposal site would be via Lockhart – Collingullie Road. Vehicle movements form the Treasure Street spoil site would also be via Lockhart – Collingullie Road, via Brookong Street and East Street.

3.4 Compound and stockpile site

A temporary site compound and stockpile site would be established within the Government Dam site.

In general, the facilities at the compound site would include toilet facilities, secure bunded areas for the storage of fuels and chemicals and designated parking and waste management areas. A site office will be established if required.

The stockpile site would be required for storing construction materials. The stockpile site would be located:

Located in areas not prone to flash flooding and more than 40 metres from a watercourse


Located more than 100 metres from occupied residences on Galore Street

Located in areas previously disturbed that do not require the clearing of native vegetation where possible

Located in plain view of the public to deter theft and illegal dumping

Stockpiles would be located outside the drip line of trees and would be on level ground wherever possible.

The stockpile site would be temporary for the period of construction and would be rehabilitated before the completion of construction.

3.5 Public utility adjustment

There is an existing 25 millimetre water service located along the southern boundary of the Government Dam site. The service is to be located on site prior to the commencement of works and the depth adjusted if necessary beneath the levee.

A Telstra utility is located in the eastern road reserve of Lockhart – Collingullie Road, and also south-east through the Travelling Stock Reserve (TSR). The contractor is required to locate the Telstra services prior to construction and modify the channel to avoid the utility if necessary.

3.6 Property acquisition

The majority of construction would take place on Crown Land in the form of the Town Common (Government Gam site) and a TSR managed by Local Land Services - Riverina, and within Council owned road reserve. A small portion of the proposal east of the TSR is located in private land, with the land owner in agreement of the proposal. There will be a need for land acquisition for creating an easement for the channel and berm footprint within the portion of private land.


4. Statutory and planning framework

4.1 Environmental Planning and Assessment Act 1979

4.1.1 Overview

The Environmental Planning and Assessment Act 1979 (EP&A Act) provides the statutory basis for planning and environmental assessment in NSW. The Minister for Planning and Infrastructure, statutory authorities and local councils are responsible for implementing the EP&A Act. The EP&A Act provides the framework for environmental planning and development approvals and includes provisions to ensure that the potential environmental impacts of a development are assessed and considered in the decision making process.

The need or otherwise for development consent is set out in environmental planning instruments – State Environmental Planning Policies (SEPPs), or Local Environmental Plans (LEPs).

4.1.2 Part 5 environmental assessment and determining authority

The proposal constitutes an activity and is permissible without development consent under State Environmental Planning Policy (Infrastructure) 2007 (ISEPP) (see section 4.2.1). The proposal is therefore subject to Part 5 of the EP&A Act.

Part 5 of the EP&A Act provides for the control of ‘activities’ that do not require development consent or the approval of the Minister for Planning and Infrastructure.

Section 110 of the EP&A Act defines ‘determining authority’ as follows:

‘determining authority means a Minister or public authority and, in relation to any activity, means the Minister or public authority by or on whose behalf the activity is or is to be carried out or any Minister or public authority whose approval is required in order to enable the activity to be carried out.’

The EP&A Act’s definition of ‘public authority’ (section 4) includes: ‘(a) a public or local authority constituted by or under an Act’.

For the purposes of the proposal, Council is the determining authority in accordance with the EP&A Act (see section 4.2.1).

The duties of the determining authority are set out in section 111 of the EP&A Act. Section 111(1) requires that a determining authority ‘…examine and take into account to the fullest extent possible all matters affecting or likely to affect the environment by reason of that activity.’

Section 112 provides that a determining authority shall not approve or carry out an activity that is likely to significantly affect the environment (including critical habitat) or threatened species, populations or ecological communities, or their habitats, unless it has considered an environmental impact statement in respect of the activity. In addition, if the proposal was to be carried out on land that is critical habitat, or if the determining authority decides the proposal would be likely to significantly affect a threatened species, population or ecological community or its habitat, then it must obtain and consider a species impact statement.

Section 5A of the EP&A Act includes an assessment of significance, which uses seven factors to assist in determining if the proposed development or activity ‘is likely to have a significant effect on threatened species, populations or ecological communities, or their habitats’. These seven factors must be taken into account by a consent or determining authority when considering a development proposal or development application. This enables a decision to be


made as to whether there is likely to be a significant effect on the species, population or ecological community, and hence if a species impact statement is required.

This REF has been prepared to consider whether the proposal would have a significant impact on the environment under Section 111 of the EP&A Act. Factors that need to be taken into account when considering the likely impact of an activity on the environment are outlined in clause 228 of the EP&A Regulation and are discussed in Appendix A.

4.2 State Environmental Planning Policies

4.2.1 State Environmental Planning Policy (Infrastructure) 2007

State Environmental Planning Policy (Infrastructure) 2007 (ISEPP) aims to facilitate the effective delivery of infrastructure across the State.

Clause 50(1) of the ISEPP states that development for the purpose of flood mitigation work may be carried out by or on behalf of a public authority without consent on any land. This includes development for any of the following purposes if the development is in connection with flood mitigation work:

Construction works

Routine maintenance works

Environmental management works.

Therefore, the proposed construction works for flood mitigation is permitted without consent.

4.3 Local planning instruments

4.3.1 Lockhart Local Environment Plan 2012

The provisions of the Lockhart Local Environmental Plan 2012 (Lockhart LEP) do not apply to the proposal due to the application of the ISEPP. Nevertheless, consideration is given below to the provisions of the LEP.

The proposal is located within the RU1 – Primary Production land use zone and flood mitigation works are generally prohibited in the RU1 – Primary Production zone.

While the proposal may remove a small area of land zoned under the RU1 – Primary Production zone for the construction of the flood mitigation measures, it would not alter the current land use in the zone.

4.4 Other relevant state legislation

4.4.1 Crown Lands Act 1989

The Crown Lands Act 1989 is the current legislation for the administration of State lands in NSW. The objects of this Act are to ensure that Crown land is managed for the benefit of the people of New South Wales and in particular to provide for:

A proper assessment of Crown land

The management of Crown land having regard to the principles of Crown land management contained in this Act

The proper development and conservation of Crown land having regard to those principles


The regulation of the conditions under which Crown land is permitted to be occupied, used, sold, leased, licensed or otherwise dealt with

The reservation or dedication of Crown land for public purposes and the management and use of the reserved or dedicated land

The collection, recording and dissemination of information in relation to Crown land.

Section 155 (1) of the Crown Lands Act 1989 states that a person shall not, without lawful authority, clear, dig up or cultivate public land. As such, any flood mitigation works within Crown land that includes these activities would require approval from the NSW Department of Industry - Lands. The Town Common is under the care of the Common Trust. An approval letter has been received from the Common Trust for the proposal. The TSR is under the care of the Local Land Services - Riverina and approval has been granted (see consultation correspondence in Appendix I).

4.4.2 Water Management Act 2000

The Water Management Act 2000 controls the carrying out of activities in or near water sources in NSW, the extraction and use of water and the construction of works such as dams and weirs. ‘Water sources' are defined as a river, lake, estuary, place where water occurs naturally on or below the surface of the ground or NSW coastal waters.

Under section 91D(1) of the Water Management Act 2000, an approval is required to construct or use flood work. A flood work includes the following:

Work that is situated in or near a river, estuary or lake, or within a floodplain; and

Affects the flow of water to or from a river, estuary or lake, or the distribution or flow of floodwater in times of flood, because of its size or configuration; and

Includes all associated pipes, valves, metering equipment and other equipment.

A local council does not need to obtain a flood work approval if the flood work is constructed or used in accordance with a development authorisation granted by a Council and the work is:

Located in an area to which a council plan or study applies, or

Not located in a floodway or Zone A or D under a floodplain management plan.

The proposal would occur on waterfront land adjacent to Brookong Creek and is considered flood work due to the construction of a levee. Council is exempt from the need to obtain a flood work approval for the proposal as Council is the proponent and a floodplain risk management study and associated plan has been developed in accordance with the Floodplain Development Manual.

4.4.3 Roads Act 1993

The objectives of this Roads Act 1993 are:

To set out the rights of members of the public to pass along public roads

To set out the rights of persons who own land adjoining a public road to have access to the public road

To establish the procedures for the opening and closing of a public road

To provide for the classification of roads

To provide for the declaration of the RMS and other public authorities as roads authorities for both classified and unclassified roads


To confer certain functions (in particular, the function of carrying out road work) on the RMS and on other roads authorities

To provide for the distribution of the functions conferred by this Act between the RMS and other roads authorities

To regulate the carrying out of various activities on public roads.

Under Section 138 of the Roads Act 1993 a person must not “erect a structure or carry out a work in, on or over a public road, or dig up or disturb the surface of a public road” otherwise than with the consent of the appropriate roads authority. The proposal would involve work on Lockhart-Collingullie Road for the installation of additional culvert structures. As Council is the road authority, no additional consent is required.

4.4.4 Protection of the Environment Operations Act 1997

The Protection of the Environment Operations Act 1997 (POEO Act) establishes, amongst other things, the procedures for issuing of licences for environmental protection on aspects such as waste, air, water and noise pollution control. The owner or occupier of premises engaged in scheduled activities is required to hold an environment protection licence and comply with the conditions of that licence.

The proposal would not involve any scheduled activities listed under Schedule 1 of the POEO Act, therefore an application for an environment protection licence is not required.

With appropriate erosion and sediment controls implemented, the proposal is unlikely to cause water pollution. Therefore, an environment protection licence under the POEO Act is not required.

The POEO Act creates a number of pollution offences. If a ’pollution incident’ were to occur during the proposal causing or threatening ’material harm’ to the environment, Council would be obliged to notify the NSW Environment Protection Authority (EPA) immediately.

4.4.5 Fisheries Management Act 1994

The Fisheries Management Act 1994 (FM Act) aims to conserve, develop and share the fishery resources of the State for the benefit of present and future generations including conserving fish stocks and fish habitat and promoting ecologically sustainable development.

The FM Act requires an assessment of whether threatened species of fish and aquatic vegetation, populations or ecological communities are likely to be affected by the proposal. If a significant impact on a threatened species, population or ecological community is likely, a species impact statement must be completed and consultation with the NSW Department of Primary Industries (Fishing and Aquaculture) is required.

The Act lists key threatening processes under Schedule 6 that are likely to impact on watercourses and threatened biota, including degradation of native riparian vegetation along NSW watercourses, and installation and operation of in-stream structures and other mechanisms that alter natural flow regimes of rivers and streams.

The FM Act requires a permit for certain work including dredging, reclamation or work that blocks fish passage. The proposal would not involve work in Brookong Creek and is unlikely to require a permit under the FM Act.

4.4.6 National Park and Wildlife Act 1974

The National Parks and Wildlife Act 1974 provides the basis for legal protection and management of Aboriginal sites within NSW, and for the management of National Parks estate.


Section 90 of the Act specifies that the Director-General may issue an Aboriginal heritage impact permit in relation to a specified Aboriginal object, place, land, activity or person, or specified types or classes of these. An Aboriginal heritage impact permit may be issued subject to conditions, or unconditionally.

Aboriginal heritage impact permits must be obtained before the commencement of any project that would, or would be likely to, impact on Aboriginal objects or places. A specialist heritage assessment was conducted for the proposal, which identified a number of Aboriginal heritage items in the vicinity of the Government Dam levee (see section 6.8). The proposal will be altered in order to avoid any impacts on these items.

4.4.7 Threatened Species Conservation Act 1995

The Threatened Species Conservation Act 1995 (TSC Act) lists a number of threatened species, populations and ecological communities to be considered in deciding whether there is likely to be a significant impact on threatened biota, or their habitats. If any of these could be impacted by the proposal, an assessment of significance that addresses the requirements of section 5 of the EP&A Act must be completed to determine the significance of the impact.

The potential for impacts on ecology have been considered in section 6.1. The assessment concludes that the proposal would be unlikely to have a significant impact on any threatened species, populations or ecological communities listed under the TSC Act. A species impact statement is therefore not required.

4.4.8 Noxious Weeds Act 1993

The objectives of the Noxious Weeds Act 1993 include:

Identify noxious weeds in respect of which particular control measures need to be taken, and specifying those control measures

Specify the duties of public and private landholders as to the control of those noxious weeds

Provide a framework for the state-wide control of those noxious weeds by the Minister and local control authorities.

Under this Act, noxious weeds have been identified for local government areas and assigned control categories. Part 3 provides that occupiers of land (including owners of land) have responsibility for controlling noxious weeds on the land they occupy.

Two noxious weeds were identified in the study area, identified in section 6.1. The potential impacts of the proposal relating to noxious weeds, and site specific safeguards, are included in section 6.1.

4.4.9 Heritage Act 1977

The Heritage Act 1977 (Heritage Act) is concerned with all aspects of heritage conservation ranging from basic protection against indiscriminate damage and demolition of buildings and sites, through to restoration and enhancement.

Heritage places and items of particular importance to the people of NSW are listed on the State Heritage Register. Only those heritage items that are of State significance are listed on the State Heritage Register. Approval under Section 60 of the Heritage Act may be required for impacts to a listed heritage item.

None of the items listed on the State Heritage Register are present within the study area.


4.5 Commonwealth Legislation

4.5.1 Environment Protection and Biodiversity Conservation Act 1999

Under the EPBC Act a referral to the Australian Government is required for proposed actions that have the potential to significantly impact on matters of national environmental significance or the environment of Commonwealth land. The impacts of the proposal on matters of national environmental significance are considered in chapter 6 and Appendix A of this REF.

This REF finds that the proposal is unlikely to have a significant impact on any matters of national environmental significance. Accordingly, the proposal has not been referred to the Australian Government Department of the Environment and Energy.

4.6 Confirmation of statutory position

An assessment of the relevant statutory planning instruments has concluded that the proposal can be assessed under Part 5 of the EP&A Act, by Council as the proponent and determining authority.


5. Consultation

5.1 Community involvement

5.1.1 Consultation conducted for Floodplain Risk Management Study

A community consultation program was carried out for the Lockhart Floodplain Risk Management Study (WMA Water 2014a), which included:

Questionnaire distribution

Community consultation open day

Flood Risk Management Committee meetings

Public exhibition of the draft final Flood Study and Floodplain Risk Management Study and Plan.

Consultation was also conducted during the Flood Study completed by WMAwater (2014b) to assess the flood experience of the community and gather additional data.

The community input to the Floodplain Risk Management Study, was used to guide the outcomes of the study and has ultimately influenced the development of the flood mitigation measures proposed for the Lockhart area, including the proposal.

5.1.2 Ongoing community consultation

Consultation has been undertaken with the community and affected residents. Property owners located in the vicinity of the proposal site would be notified before the commencement of construction.

5.2 ISEPP consultation

Clauses 13 to 16 of the ISEPP require that public authorities undertake consultation with councils and other public authorities for certain activities when proposing to carry out development without consent.

The proposal does not trigger any of the requirements for ISEPP consultation under these clauses. Formal ISEPP consultation is not required.

5.3 Government agency and stakeholder involvement

5.3.1 Information provided to government agencies

Consultation on the REF has been undertaken with government agencies that may have an interest in the proposal. Consultation was conducted by written notification requesting comments or issues to be addressed during the preparation of the REF. A consultation letter and map were issued on 31 January 2017. Agencies notified included:

Department of Primary Industries – Water

Local Land Services - Riverina.

Email responses were received from both agencies (see Appendix I). Issues raised in the response are summarised in section 5.3.2


5.3.2 Issues raised by government agencies

An email response to consultation was received from Local Land Services. There are no perceived issues for Local Land Services, stating they would like to be informed when the work is starting to avoid the area with travelling stock until work is completed. There would be no impact on stock access and water.

An email response was received by Water NSW, who have taken responsibility for water compliance issues from Department of Primary Industries – Water. It was advised that Council would be exempt from requiring a flood work approval for work on the floodplain on the basis that (see section 4.4.2 for further details):

Council are the determining authority

Development consent under the EP&A Act will be sought

A flood risk plan in accordance with the Floodplain Development Manual has been completed.


6. Environmental assessment

6.1 Biodiversity

6.1.1 Methodology

Desktop review

The assessment included a review of background ecology information obtained from database searches and reviews. These searches included:

OEH Atlas of NSW Wildlife database– licensed data for Lockhart local government area. Search of all terrestrial threatened flora and fauna species (within a 10 kilometre radius of proposal site) (searched January 2017) (OEH 2017a).

OEH (2017b) NSW threatened species, online profiles.

DotEE (2017a) EPBC Act Protected Matters Search Tool – for a 10 kilometre radius around the proposal site (searched January 2017).

DotEE (2017b) Species profile and threats database, online profiles.

DPI – noxious weed declarations – Lockhart LGA control area (DPI 2017) (searched January 2017).

Field surveys

Flora and fauna field surveys were conducted by two ecologisst on 12 January 2017. Where appropriate, field surveys were conducted in accordance with the ‘Threatened Biodiversity Survey and Assessment: Guidelines for Developments and Activities Working Draft’ (DEC 2004).

The primary objectives of the field surveys were to:

Determine the presence and/or potential for threatened flora and fauna species, populations, ecological communities, listed under the NSW TSC Act and Commonwealth EPBC Act, and their habitats to occur in the study area.

Determine the value of the habitat in the study area for flora and fauna species, particularly for threatened species and species of conservation significance, and describe potential impacts that would result from the proposal.

Describe the flora and fauna species, habitat, populations and ecological communities in the study area in relation to their occurrence and quality in the locality. This included ground truthing, reference to aerial photographs and vegetation mapping.

Determine the condition and extent of vegetation removal required for the proposal.

Survey effort for this proposal is summarised in Table 6.1.

Table 6.1: Survey effort for ecology/biodiversity

Survey method Effort Flora plot (see Figure 6-1) Two 20 metre by 50 metre plots (with a nested 20

metre by 20 metre plot) in the study area. Flora transect A flora survey transect along the entire length of

the proposal site. Fauna habitat assessment Potential fauna habitat identified within areas of

potential vegetation clearing and adjacent areas.


Survey method Effort Opportunistic fauna observations Opportunistic fauna observations for all fauna

species encountered during flora surveys and habitat assessment.

Flora

Flora surveys were conducted in the study area using plot surveys (see Figure 3-1 for location of spoil site where plot 1 was conducted and Figure 6-1 for location of plot 2 in the proposal site) and random meandering transect surveys.

Two 20 metre by 50 metre flora survey plots were surveyed. Within the plot, the following vegetation and habitat characteristics were recorded:

Description of vegetation

Groundcover species and abundance

Any signs of previous disturbance and grazing.

A flora survey transect was surveyed along the entire length of the proposal site. As rare plants often exist in discrete populations in specific areas, a random search can increase the probability of finding rare plant populations. A random search effort also encompasses a greater portion of the landscape, as the search is not limited to specific areas (only the stratification unit), and is useful in surveying difficult terrain and irregular shaped search areas.

Vegetation mapping

Surveys of vegetation communities along the proposal site were undertaken to characterise vegetation formation, class, structure and condition. Plant community composition is especially important for those areas that have the potential to be a threatened ecological community.

Flora surveys enabled determination of the composition and extent of ecological communities occurring in the study area. The study area was investigated by random meandering transect to identify vegetation communities present and to identify any areas with the potential to be classified as a threatened ecological community.

Native vegetation in the study area was initially assigned a vegetation community name based on observed floristic and structural characteristics. Intact native vegetation communities were defined according to NSW Plant Community Type (PCT) classifications used in the OEH Vegetation Information System (OEH 2017c).

Introduced or highly modified native vegetation was defined based on structure and species composition.

All vegetation communities were mapped using aerial photographic interpretation guided by the field survey results and GPS data.

For areas with the potential to classify as a threatened ecological community, an analysis was undertaken using the criteria for classification under the TSC Act and EPBC Act.

Survey timing and potential limitations

Surveys were undertaken outside the optimal survey period for some species. Surveys were undertaken in mid-January 2017. Many plant species are not detectable at these times of the year because they have finished flowering or have not yet flowered. For threatened flora species that were not detectable at the time of the survey, but which had the potential to occur at the site, an assessment was made of the suitability of the habitat for the species and its likelihood of occurrence.


Some fauna species are mobile and transient in their use of resources. Consequently, it is likely that not all species either resident or transitory to the site would have been recorded during field surveys. The disadvantage of this limitation was reduced by undertaking database searches, and by assessing the habitat value of the study area for threatened and migratory species known to occur in the wider area to determine their likelihood of occurrence.

This survey was not designed to enable all species, either resident or transitory to the study area, to be detected. Instead it was aimed at providing an overall assessment of the ecological values of the study area with particular emphasis on threatened and migratory species to allow an assessment of the potential impacts of the proposal. For those species of conservation significance that were not detected but with the potential to occur in the study area, an assessment of the likelihood of their occurrence was made based on known habitat requirements.

Fauna

Fauna surveys comprised a habitat assessment for all fauna groups, observations of fauna signs and opportunistic observations of fauna during flora surveys. Fauna habitat resources were assessed to identify areas of potential habitat within the study area. Specific resources such as shelter, basking, roosting, nesting and foraging sites for birds, bats, arboreal mammals, amphibians, ground-dwelling mammals and reptiles were noted.

Habitat assessment

Habitat details recorded included presence or absence of:

Hollow-bearing trees (arboreal mammals, hollow-nesting birds and microchiropteran bats)

Woody debris (birds and reptiles)

Feed trees (e.g. Allocasuarina spp. and mistletoe)

Waterbodies (amphibians)

Nests (birds)

Rocky outcrops (reptiles)

Other features likely to provide potential habitat for threatened fauna.

Searches for potential mammal, amphibian, and reptile habitat were undertaken and recorded during flora surveys.

Birds

Species observed at other times (such as during flora surveys) were recorded as opportunistic observations.

Observations of fauna signs

Any indirect evidence of fauna (e.g. scats, feathers, fur, tracks, dens, nests, scratches, chew marks and owl wash) was recorded and/or photographed.

Assessment of the likelihood of occurrence of listed biota

An assessment of the likelihood of occurrence and possibility of impact was completed for listed species, populations and ecological communities with the potential to occur in the study area.

In assessing which of these species, populations and ecological communities are ‘likely’ to occur within the study area (as described in ‘Threatened Biodiversity Survey and Assessment: Guidelines for Developments and Activities Working Draft’) (DEC 2004) the following factors were taken into consideration:


The presence of potential habitat within the study area.

Condition and approximate extent of potential habitat within the study area.

Species occurrence within the locality and region (including results of current and previous surveys and results of database searches and literature review).

In addition, the possibility of impact by the proposal on threatened biota likely to occur, or be present was assessed, and therefore whether an EP&A Act assessment of significance and/or EPBC Act significance assessment is required to assess the significance of the impact.

Assessment of the potential impacts on listed biota

An assessment of significance was completed for an ecological community identified as being likely to be impacted by the proposal (Weeping Myall Woodland).

Potential impacts on the TSC Act listing of the ecological community were assessed in accordance with the Assessment of Significance included in section 5A of the EP&A Act, with reference to DECC (2007) (see Appendix D).

Potential impacts on the EPBC Act listing of the ecological community were assessed in accordance with the EPBC Act Policy Statement ‘Matters of National Environmental Significance: Significant impact guidelines 1.1’ (DotE 2013) (see Appendix D).

6.1.2 Existing environment

Flora species

Field surveys identified 70 flora species, of which 34 are native and 36 are introduced (see Appendix B).

The proposal occurs in Crown Land known as the Lockhart Town Common, roadside reserve along Galore Street, and in a TSR to the south east of Lockhart-Collingullie Road. The levee footprint occurs in an area previously cleared of native vegetation with the groundcover dominated by introduced species including Wild Oats (Avena fatua), Spear Thistle (Cirsium vulgare) and Barley Grass (Hordeum leporinum). Commonly occurring native species include Bluebushes (Maireana species) and Plains Grass (Austrostipa aristiglumis), which dominates the groundcover in the area of the proposed spillway.

Mature trees occur outside the proposed footprint of the levee and include River Red Gum (E. camaldulensis), Yellow Box (E. melliodora) and White Cypress Pine (Callitris glaucophylla). There are scattered paddock trees and small clumps of Grey Box in the Town Common, and roadside reserve of the Lockhart-Collingullie Road and Galore Street. Planted trees also occur along the roadside reserve of Lockhart-Collingullie Road, and include species such as Belah (Casuarina cristata).

The channel and berm footprint for the TSR traverses mostly cleared open paddock and a small patch of remnant woodland. The dominant tree species in the TSR is Weeping Myall (Acacia pendula) and individual trees of this community occur as a mixed age stand of old trees, middle age trees and some regeneration. The groundcover is dominated by native species, including Plains Grass and Speargrass (Austrostipa scabra), with Barley Grass (Hordeum leporinum) the most common introduced species occurring.

The Treasure Street spoil site is highly disturbed and dominated by introduced groundcover species such as Wild Oats. Native species that occur sporadically include Hairy Panic (Panicum effusum) and Windmill Grass (Chloris truncata). There are no trees or shrubs located in the area the spoil would be taken from.


Shrubs were sparse throughout the study area with only a one native shrub species recorded, Western Silver Wattle (Acacia decora).

No threatened flora species listed under the TSC Act or EPBC Act were recorded in the study area.

Noxious weeds

Two species listed as noxious for the Lockhart Shire Council control area were identified during the field surveys; White Horehound (Marrubium vulgare) and Lippia (Phyla canescens) (DPI 2017). Both species are class 4 locally controlled weeds, meaning the growth of the plant must be managed in a manner that continuously inhibits the ability of the plant to spread. Lippia must not be sold, propagated or knowingly distributed except incidentally in hay or Lucerne.

Plant Community Types

Plant Community Types (PCTs) in the study area are shown in Figure 6-1.

The woodland in the TSR where the channel and berm would be constructed classifies as the PCTID 26 - Weeping Myall open woodland of the Riverina Bioregion and NSW South Western Slopes Bioregion. This PCT in the TSR is dominated by Weeping Myall and forms part of a State and Commonwealth listed endangered ecological community of:

TSC Act - Myall Woodland in the Darling Riverine Plains, Brigalow Belt South, Cobar Peneplain, Murray-Darling Depression, Riverina and NSW South Western Slopes bioregions

EPBC Act – Weeping Myall Woodland.

The Commonwealth listing advice for this community has more condition restrictions than the NSW listing. However, the patch of Weeping Myall Woodland south of Lockhart-Collingullie Road meets the definition of both the NSW and Commonwealth listing for this community due to the predominantly native understorey and presence of overstorey regeneration. This community occurs in the study area and proposal site east of Lockhart – Collingullie Road (see Figure 6-2).

The eastern end of the proposed channel and berm east of Lockhart – Collingullie Road runs parallel to a small patch of Grey Box (Eucalyptus microcarpa). These trees occur as four isolated paddock trees in a grazed paddock dominated by introduced groundcover species. The woodland in the study area dominated by Grey Box with White Cypress Pine classifies as PCTID 80 – Western Grey Box – White Cypress Pine tall woodland on loam soil on alluvial plains of NSW South Western Slopes Bioregion and Riverina Bioregion. Trees and groundcover of this community form part a State and Commonwealth listed endangered ecological community:

TSC Act - Inland Grey Box woodland in the Riverina, NSW South Western Slopes, Cobar Peneplain, Nandewar and Brigalow Belt South bioregions

EPBC Act – Grey Box grassy woodlands and derived native grasslands of south-eastern Australia.

The Commonwealth listing advice for this community has more condition restrictions than the NSW listing. The Grey Box Woodland in the study area is part of the NSW listing of the community but does not qualify as part of the Commonwealth listing of the community due to the degraded understorey.

Woodland in the northern section of the study area, which is dominated by River Red Gum and/or Yellow Box and contains a grassy groundlayer classifies as PCTID 74 – Yellow Box – River Red Gum tall grassy riverine woodland of NSW South Western Slopes Bioregion and Riverina Bioregion. This community does not classify as a threatened ecological community.

Fauna

Fauna species

Surveys undertaken by GHD identified 17 fauna species, of which only one was introduced, the Common Starling (Turdus merula) (see Appendix B). The trees within the study area provide habitat for a number of bird species and all fauna species recorded during surveys were birds.

Commonly recorded birds included Australian Raven (Corvus coronoides), Willie Wagtail (Rhipidura leucophrys) and Australian Magpie (Cracticus tibicen). One threatened species was recorded during surveys; the Grey-crowned Babbler (Pomatostomus temporalis temporalis), which is listed as vulnerable under the TSC Act. The species was heard calling within the TSR and then observed in a Grey Box tree in the road reserve of Galore Street.

No mammals were recorded during field surveys; however native mammals likely to occur include the Eastern Grey Kangaroo (Macropus giganteus), Common Brushtail Possum (Trichosurus vulpecula) and White-striped Freetail Bat (Tadarida australis). Introduced mammals likely to occur include the Fox (Vulpes vulpes), Cat (Felis catus) and European Rabbit (Oryctolagus cuniculus).

No amphibian species were heard calling within the study area, this is likely to have been due to high temperatures experienced during the survey period. The dams and creek in the study area provide potential habitat for amphibians to occur.

No species of reptile were recorded during surveys, however species likely to occur include skinks such as the Tree Skink (Egernia striolata) and snakes such as the Eastern Brown Snake (Pseudonaja textilis).


Fauna habitat

Fauna habitat in the study area occurs mainly in remnant native vegetation along roadsides and Brookong Creek, in the Town Common and TSR, and in woodland north of the Town Common. There is marginal habitat provided by mixed introduced and native grasslands through the surrounding heavily grazed paddocks

Remnant vegetation in the study area provides potential foraging and breeding habitat for a variety of bird species.

Grey-crowned Babblers, and other species, are likely to use vegetation corridors in the study area as movement corridors. The connectivity of these corridors aids in facilitating the movement of a range of fauna across the landscape, including woodland birds, mammals and other fauna.

Hollow-bearing trees occur throughout the study area. Hollow-bearing trees in the study area are likely to provide potential roosting and nesting habitat for microchiropteran bats (such as the White-striped Freetail Bat), arboreal mammals (such as the Common Brushtail Possum) and a range of woodland birds.

Grassland areas in the study area are likely to provide foraging habitat for mammals such as the Eastern Grey Kangaroo. Grassy areas are also likely to provide foraging habitat for woodland birds, including threatened species such as the Superb Parrot (Polytelis swainsonii).

Woody debris in the study area is likely to provide suitable habitat for commonly occurring reptiles such as skinks and snakes.

Likelihood of occurrence of threatened biota

TSC Act listed biota

The literature review, database search and field surveys identified three ecological communities, five flora species, 17 birds, seven mammals, two reptiles and two frogs listed under the TSC Act that could potentially occur in the locality (see Appendix C).

Of these, two ecological communities and one bird species listed under the TSC Act were recorded and/or have a high or moderate likelihood of occurrence in the study area (see Appendix C). These biota are listed in Table 6-2.

For those species, populations or ecological communities for which the likelihood of occurrence was recorded, high or moderate, an EP&A Act assessment of significance (Appendix D) was prepared to assist in determining the significance of the potential impacts of the project on threatened biota. These assessments conclude that the project is unlikely to significantly impact on any threatened biota listed under the TSC Act.

EPBC Act matters of NES

The literature review, database search and field surveys identified two ecological communities, three flora species, five birds and two mammal species listed under the EPBC Act that could potentially occur in the locality (see Appendix C).

Of these, one ecological community and one bird species listed under the EPBC Act were recorded or have a high or moderate likelihood of occurrence in the study area (see Appendix C). These biota are listed in Table 6-2.

For those species, populations or ecological communities for which the likelihood of occurrence was recorded, high or moderate, significant impact guidelines were prepared to assist in determining the significance of the potential impacts of the project on matters of NES (Appendix


D). These assessments conclude that the project is unlikely to significantly impact on any threatened biota listed under the EPBC Act.

Potential direct impacts

Construction

Native vegetation/habitat removal

The proposal would remove the following areas of native vegetation (see Figure 6-1):

Weeping Myall Woodland in the form of groundcover species – about 500 square metres (0.05 ha)

One isolated Weeping Myall tree (not part of the endangered community)

Four Grey Box trees

Six planted Acacias

Six planted Belah trees

The removal of Weeping Myall Woodland is from within the TSR and includes a 10 metre corridor for the channel and berm construction (Figure 6-2). Removal of the community would be limited to grassland, with trees to be retained. The grassland has been substantially modified by grazing and does not contain a high diversity of native flora species, however still classifies as the EPBC Act listed community due to the patch containing a predominantly native understorey.

Tree removal occurs from within the road reserve of Galore Street and at its intersection with Lockhart – Collingullie Road (Figure 6-3).

The loss of native vegetation may represent a loss of foraging and movement habitat for fauna species, including birds such as the Grey-crowned Babbler; however, this would be minor given the much greater extent of habitat in the study area and the small area of mostly paddock trees over an introduced groundlayer to be removed. The trees to be removed are unlikely to provide important habitat for fauna species and no hollow-bearing trees would be removed.

In all other parts of the proposal site, the groundcover vegetation to be removed is dominated by introduced species (Figure 6-4).

Potential indirect impacts

Water quality, chemical and fuel impacts on flora and fauna

The proposal has the potential to cause impacts to native flora and fauna through spills of fuels and chemicals. This may occur during refuelling operations or during preparation and use of chemicals for weed management. Spills could potentially contaminate habitat for species dependent on drainage lines.

The proposal site is in the vicinity of Brookong Creek and Government Dam, however with the implementation of safeguards it is unlikely that the proposal could cause sedimentation or water quality impacts which could reach downstream waterbodies.

The proposal could also potentially affect flora through spray drift during application of herbicides.

These impacts would be unlikely to be substantial due to the limited area of impact and the implementation of safeguards detailed in section 6.1.4.

Weeds

The groundcover vegetation in the study area contains a range of introduced species including two declared noxious species. The proposal has the potential to introduce and further spread weeds in the study area through the movement of machinery and light vehicle traffic and disturbance associated with vegetation removal and earthworks. The proposal has the potential to spread the two noxious weeds recorded into new areas and to introduce new noxious weed species to the area.

The implementation of safeguards detailed in section 6.1.4 would limit the potential for the spread of weeds associated with the proposal.


Disturbance of fauna

The proposal has the potential to temporarily affect the use of the study area by fauna as a result of increased disturbance during construction. The use of machinery may temporarily deter some fauna species such as birds from using potential habitat in the study area during construction.

Cumulative impacts

The proposal would cause impacts additional to those that have occurred due to previous land use activities in the study area; including agricultural activities and construction and maintenance of roads (e.g. Lockhart-Collingullie Road) and utilities. Other works that may contribute to cumulative ecological impacts in the study area include loss of vegetation through maintenance of linear infrastructure such as roads and powerlines. Given the small scale of vegetation removal involved, and the degraded nature of the groundcover vegetation proposed to be removed, it is unlikely that the proposal would cause significant cumulative ecological impacts.

Key threatening processes

One key threatening process listed under the TSC Act and EPBC Act is relevant to the proposal; clearing of native vegetation. This includes the Weeping Myall ecological community and a small number of trees as described above.

Summary of impact assessment

The literature review, database search and field surveys identified a number of species and two ecological communities listed under the EPBC Act and/or TSC Act known or likely to occur in the study area. Of these, only Weeping Myall Woodland has the potential to be impacted by the proposal. Impacts to listed fauna are likely to be negligible.

Weeping Myall Woodland and Grey Box woodland are listed as endangered ecological communities under the TSC Act and EPBC Act. The Grey-crowned Babbler is listed as vulnerable under the TSC Act. An assessment of significance (7 part test) was applied under section 5A of the EP&A Act and a significance assessment as detailed in the policy statement Matters of National Environmental Significance: Significance impact guidelines 1.1 (DEWHA 2009) was used to assist in determining if a significant impact is likely (see Appendix D).

The assessment found that the proposal would be unlikely to have a significant impact on this species and communities due to the small scale of vegetation removal involved.

The proposal is unlikely to impact on any other threatened ecological communities or threatened species due to the minor nature of impacts of the proposal, its location in a previously disturbed environment, the small area of native vegetation to be removed, and the presence of additional, higher quality habitat outside of the proposal site.

6.1.4 Safeguards and management measures

Impact Safeguard Responsibility and timing

Loss of native vegetation habitat

All staff will be inducted and informed of the limits of vegetation clearing and the areas of vegetation to be retained. Areas of vegetation not to be removed will be clearly marked prior to construction

Council and Project manager

Pre-construction



Pre-clearing surveys will be completed to establish exclusion zones and on-ground identification of specific habitat features to be retained (e.g. hollow-bearing trees)

Temporary exclusion fencing will be erected to prevent encroachment and clearing of remnant vegetation beyond the construction footprint

Stockpiles of construction materials, fill or vegetation will be restricted to existing cleared areas and not within areas of adjoining native vegetation

Where possible, the detailed design of the proposal will incorporate measures to minimise vegetation removal, particularly Weeping Myall Woodland


Removal of native vegetation will be minimised wherever possible

Pruning or lopping of limbs will be conducted in preference to tree removal wherever possible.

Spread of weeds

A weed management plan will be prepared before works commence, to be implemented before, during and after the works. The plan would include measures to prevent the spread of weeds, particularly noxious species in the study area including:

– Horehound

– Lippia

Declared noxious weeds will be managed according to requirements under the NSW Noxious Weeds Act 1993

Soil disturbance will be avoided as much as possible to minimise the potential for spreading weeds and generating sediment.

Vehicle and machinery wash/brush downs may be required to ensure that noxious weed species are not spread to previously non-infested areas, particularly remnant native vegetation.

Project manager

Pre-construction and construction

Chemical and fuel impacts on native vegetation

Any herbicides used for weed control will be applied to the manufacturer's specifications and as outlined in the manufacturers Material Safety Data Sheet

Broad spectrum non-selective herbicides (residual herbicides) will not be used. Herbicides selected for use will be appropriate for the species being treated

Spraying of herbicides will not be undertaken in windy weather or within such distance of a watercourse as will permit any of the herbicide to enter the water

Safeguards for preventing and managing spills of fuels and chemicals will be implemented as detailed in section 6.2 of this REF.

6.2 Topography, geology and soils


Topography and geology

The study area is located in the Brookong Plains Mitchell Landscape, which is comprised of Quaternary alluvial plains (Mitchell 2002). This landscape is 93 percent cleared and is therefore considered an over-cleared landscape (>70 per cent cleared). The general elevation is 170 metres above sea level. Local relief is less than 10 metres (Mitchell 2002).

The geology of the study area falls within an unnamed geological unit from the Quaternary period. This unit comprises unconsolidated riverine deposits of clay, silt, sand and gravel, and includes flood plains and black soil plains (NSW Department of Mineral Resources 2002).

The terrain of the study area is generally flat to gently undulating due to its location on the floodplain of Brookong Creek. Elevation is about 157 metres above sea level.

Soils

Soil types

The Brookong Plains Mitchell Landscape contains red-brown texture-contrast soils (Mitchell 2002).

The geotechnical investigation conducted for the proposal found silty clay, clayey silt and gravelly silt material. Some of the clays found on site are generally considered to be ‘potentially moderately to highly dispersive’ (Aitken Rowe 2016).

Acid sulphate soils

There are no known occurrences of acid sulphate soils in the study area. Based on mapping of acid sulphate soils for NSW (OEH 2013), it is unlikely that these would occur in the study area. Acid sulphate soils are generally confined to coastal areas, although they can occur at inland locations where there is poor drainage. No such environments are known to be present in the study area.

Soil contamination

A search of the EPA contaminated land register did not find any declared contaminated sites located in or near the study area. Search results are provided in Appendix E.


Land use in the study area is characterised by residential and rural properties. These land uses indicate minimal potential for contamination in the study area. Agricultural practices dominate the landscape outside the study area.


Topography and soils

Vegetation removal

About 1.5 hectares of groundcover vegetation would be removed as part of the proposal. Vegetation removal and large areas of cut and fill would expose soils to weathering processes, increasing the risk of erosion and sedimentation. Disturbed areas along the proposal site would be revegetated after construction completion.

Earthworks

The proposal would involve earthworks over the length of levee construction, as well as for the channel and berm. The proposal would involve cut and fill earthworks over an area of about 1.5 hectares, which would potentially affect topography and soils.

The topography in the vicinity of the proposal site would change from being generally flat with only a gentle slope to the top of the dam from the south, to having a relatively abrupt levee structure with sloping batters, in addition to a channel structure on the east side of Lockhart – Collingullie Road. The topsoil layer and a proportion of the surficial geology would be removed, exposing the underlying geologic layers. The volume of material proposed to be excavated at the proposal site is 5,690 cubic metres. In addition, about 2,314 cubic metres would be excavated from the Treasure Street spoil site. The change to the topography would be minimised by constructing gently sloping batters at the proposal site. Excavation at the Treasure Street spoil site would return the site to its natural topography by removing the excess spoil previously dumped there.

The construction of the levee has the potential to impact on soils and landforms. Loose fill and/or soil may be eroded during rainfall events by runoff, increasing the potential for mass movements of soils and sedimentation of local drainage lines. This may in turn influence the vegetation and habitat of adjacent areas by smothering groundcover vegetation and changing soil surface characteristics.

Construction of the spillway

The proposed construction of the spillway at the eastern end of the Government Dam site, through Brookong Creek, has the potential to cause destabilisation of the creek banks, soil erosion and sedimentation of the creek. The existing creek channel has been altered by the creation of the dam and is relatively shallow with low banks. The spillway would be constructed with gabion mattresses to protect the integrity of the creek and minimise erosion potential, and construction would be undertaken with consideration of potential soil erosion impacts.

Vehicle movements, including machinery and support vehicles

Machinery and support vehicles used for the construction of the proposal would be driven off road and would have the potential to transport excess material onto sealed roads.

Stockpiling

Excavated material would require stockpiling before being used to construct the levee and berm. Inadequately stabilised stockpile material could erode in periods of high rainfall or windy conditions. This risk would be managed by constructing the levee and berm simultaneously with the excavation of material required, minimising the need for stockpiling.


Soil contamination

There is potential for chemical and fuel spills during construction, which may result in localised contamination of soils. The potential for contamination is considered to be low provided the safeguards and management measures outlined in section 6.2.3 are implemented.

6.2.3 Safeguards and mitigation measures


Soil erosion, sedimentation and water quality

A soil and water management plan will be prepared as part of the CEMP for the proposal in accordance with the Blue Book - Soils and Construction - Managing Urban Stormwater Volume 1 (Landcom 2004) and Volume 2D (DECC 2008a)

The soil and water management plan will include but not be limited to:

– A primary erosion and sedimentation control plan and a maintenance schedule for ongoing maintenance of temporary erosion and sediment controls

– An incident emergency spill plan which will include measures to avoid spillages of fuels, chemicals, and fluids onto any surfaces or into any adjacent/nearby waterways

If considered necessary, an accredited soil conservationist may be engaged to provide advice during development and implementation of the soil and water management plan. The soil conservationist may regularly review and inspect works throughout the construction phase.

Project manager

Pre-construction

Soil erosion and sedimentation

Construction of the levee spillway will not occur during periods of flow in the Brookong Creek

Sediment and erosion controls will be installed before the commencement of earthworks.

Erosion and sedimentation controls will be checked and maintained regularly during construction

High risk soil erosion activities such as earthworks will not be undertaken immediately before or during high rainfall or wind events

Topsoil excavated at the proposal site will be stockpiled separately for reuse in landscaping and rehabilitation works

Erosion and sediment control measures will be maintained until the works are complete and areas are stabilised by revegetation.

Project manager

Construction



Soil and water contamination

All fuels, chemicals, and liquids will be stored at least 50 metres away from any drainage lines and bunded fuel trailers and utility vehicles. If storage in the compound site is necessary, fuels, chemicals and liquids will be stored in an impervious bunded area

The refuelling of plant and planned maintenance of machinery and plant will be undertaken 50 metres away from waterways

Visual monitoring of local water quality (ie turbidity, hydrocarbon spills/slicks) will be undertaken on a regular basis to identify any potential spills or deficient erosion and sediment controls. A record will be kept of these inspections

Emergency spill kits will be kept on-site at all times

All staff will be inducted about incident and emergency procedures and made aware of the locations of emergency spill kits

Should a spill occur during construction, the emergency spill plan will be implemented. The EPA will be notified as per Part 5.7 of the POEO Act.

6.3 Flooding, drainage, water quality and groundwater


Flooding

Flooding within Lockhart is caused from both Brookong Creek and major overland flooding from flow paths meeting manmade structures. Numerous flood events have occurred at Lockhart including 1931, 1934, 1939 and 1974, with major floods occurring in October 2010 and March 2012.

Hydrology and water quality

Hydrology

The study area drains via Brookong Creek, which flows from north to south through the township of Lockhart and discharges into Urangeline Creek, which drains to the Murray River via Billabong Creek and the Edward River. Brookong Creek is fed by numerous small ephemeral creek and drainage lines. At Lockhart, Brookong Creek has a catchment area of approximately 150 square kilometres. Brookong Creek is located in the western end of the proposal site.

Surface water quality

In the Lockhart Shire, there are six creeks that are classified as protected streams, including Brookong Creek. Water quality is largely influenced by adjacent land use with water clarity being


poor due to sediment runoff into the creeks and the creeks moving sediment load. Brookong Creek also receives licensed discharge from the Lockhart treatment works (LSC 2012).

Agricultural runoff may contain farm chemicals and fertilisers that degrade water quality. Agricultural runoff may also contain manure from stock, which can increase:

Biochemical oxygen demand

Levels of nutrients such as nitrogen

Levels of bacteria such as faecal coliforms.

Operation of roads leads to the build-up of contaminants (such as oil and heavy metals) on road surfaces and roadside corridors. Sediment pollution also occurs from unsealed roads, such as the eastern section of Galore Street.

Groundwater

There are no registered groundwater bores located in the study area or locality of the proposal..

In general, the depth to the watertable would vary with season, rainfall, elevation, proximity to creeks and presence of aquifers. The watertable may be closer to the ground surface in the vicinity of Brookong Creek, however, due to the nature of the works it is unlikely the watertable would be intercepted during construction.


Flooding

The proposal would provide an enhanced level of flood protection for the township of Lockhart. The levee is based on a design which achieves a levee crest with 500 millimetres of freeboard above the 100 year ARI flood level. In flood events, the levee will provide protection to the residential properties on the south side of the levee. Combined with the channel and berm on the east side of Lockhart – Collingullie Road there would be reductions in peak flood level exceeding 0.3 metres in some areas and many areas would no longer experience flooding. The proposal would reduce the average annual damage caused from flooding.

Surface water quality

The introduction of pollutants from construction of the proposal into the surrounding environment, if uncontrolled, could potentially have the following impacts on the water quality of drainage lines and dams:

Increased sediment load and organic matter causing adverse impacts to water quality in drainage lines and dams, such as increased turbidity. Provided safeguards and management measures are implemented, the proposal would be unlikely to contribute significant amounts of sediment and organic matter

Gross pollutants (large waste items) entering drainage lines and dams in the study area

Reduced water quality in drainage lines and dams due to an influx of man-made substances.

Construction activities could introduce additional materials to the local drainage lines and dams, particularly during high rainfall events. Contaminants could include rubbish and construction materials, and fuel or chemicals from accidental spills. Spills could occur during refuelling or through leaking of hydraulic and lubricating oil from plant and equipment.

The potential for construction water quality impacts to the surrounding drainage lines and dams is considered to be moderate due to the potential for soil erosion and sedimentation during construction.


Groundwater

The proposal requires excavation to about a depth of one metre below the ground surface for the levee construction to provide a levee key where required. The watertable was not encountered during the geotechnical investigation. It is generally unlikely that groundwater would be encountered during excavation. The proposal would be unlikely to have any substantial effect on groundwater systems during construction.


Impact Safeguard Timing and responsibility

Water quality and contamination

Safeguards and mitigation measures relevant to water quality and contamination are included in section 6.2.3.

Flooding Council will inform the local community of the benefits to be provided by the proposal in regards to flooding.

6.4 Landuse and property


Land uses in the study area consist of (see Figure 1-1):

Rural holdings used for agriculture including grazing and cropping

Residences to the south of the proposal site

Town Common forms the proposal site

TSR to the east of the proposal site

Lockhart town centre south of the proposal site

Existing roads, including Galore Street, Urana Street, Lockhart-Collingullie Road and East Street.

The proposal site is predominantly located on Crown Land, comprising the Town Common at the Government Dam site and a TSR east of Lockhart – Collingullie Road. The Town Common is under the care of the Common Trust.


Property acquisition

The Lockhart Town Common, where the Government Dam site is located, has an Aboriginal Land Claim lodged against it. Council is currently in the process of gaining approvals for construction. An approval letter has been received from the Common Trust. It is anticipated that there will be a need for land acquisition for creating an easement for the levee footprint.

The Aboriginal Land Claim is unlikely to be resolved in the near future to allow for prompt construction. An appeal has been lodged with the Aboriginal Land Council due to the project being for flood mitigation works that are of a relatively high priority. The proposal has been advanced on the priority list for assessment with the Aboriginal Land Council (S. Farrell pers. comm.).

The TSR east of Lockhart – Collingullie Road is managed by Local Land Services - Riverina. A small portion of the proposal east of the TSR is located in private land, with the land owner in


agreement of the proposal. There will be a need for land acquisition for creating an easement for the channel and berm footprint. About 0.1 hectares of private land would be acquired for the proposal.

The land to be acquired for the proposal is unlikely to substantially affect its current use due to the low grade of the batters of the levee and berm, and the shallow channel to be constructed. Stock would still be able to graze over the area as per the existing conditions.

The land to be acquired would not impact the use of surrounding land in the long term, however there may be some disruption to the immediate surroundings during construction.

Indirect impacts on land use

The proposal has the potential to indirectly affect land use through impacts relating to soil and water contamination, air quality and noise. These impacts are assessed in sections 6.2.3, 6.5.5 and 6.6.3. The proposal is unlikely to cause significant long-term indirect impacts to land use.



Property acquisition

All property acquisition will be undertaken in accordance with the Land Acquisition (Just Terms Compensation) Act 1991

Affected landowners and stakeholders, including the Common Trust and Local Land Services - Riverina, will be consulted on an ongoing basis regarding the status and timing of acquisition and construction

Ongoing consultation will occur with the LAC to track progress of the appeal against the Aboriginal Land Claim.

6.5 Noise and vibration

A separate noise and vibration assessment of the proposal was undertaken (GHD 2017c) and is provided in Appendix G. The outcomes of the assessment are summarised in this section.

6.5.1 Methodology

Overview

The study area for the noise and vibration assessment includes residential sensitive receivers south and south-west of the proposal site (see Figure 6-5).

To assess the potential noise and vibration impacts arising from construction and operation of the proposal, an assessment has been undertaken with consideration to the following:

Interim Construction Noise Guideline (ICNG)) (DECC 2009)

Road Noise Policy (RNP) (DECCW 2011)

Assessing Vibration: A Technical Guideline (DEC 2006).

Noise monitoring

Noise monitoring was undertaken from 12 January to 19 January 2017 in the backyard of 7 Galore Street, Lockhart, south of the Government Dam site (see Figure 6-5). Noise monitoring


was undertaken to determine background noise levels for the noise assessment. Monitoring was undertaken at the above location, which was secure from theft and vandalism and considered representative of the ambient environment in the vicinity of the proposal site.

Noise monitoring was undertaken using a Rion NL-52 environmental noise logger within calibration. The instrument was programmed to accumulate environmental noise data continuously over sampling periods of 15 minutes for the entire monitoring period.

The data collected by the equipment was downloaded and analysed, and any invalid data removed. Invalid data generally refers to periods of time where average wind speeds were greater than 5 m/s, or when rainfall occurred during the monitoring period.

Noise source emissions

The anticipated plant and equipment to be used during construction is shown in Table 6.3 with the corresponding noise emission sound power levels. Noise levels for equipment have been obtained from AS2436 – 2010 Guide to noise and vibration control on construction, demolition and maintenance sites. Other equipment than that modelled may be used, assuming they would produce similar noise emissions.

Backhoe 104

Excavator 107

Front end loader 113

Grader 110

Roller 108

Scraper 116

Truck/ Water cart 107

Noise modelling

For each construction scenario, the noise levels at the modelled sensitive receivers in the vicinity of the proposal have been predicted. Noise modelling was undertaken using SoundPLAN (v7.4). SoundPLAN is a computer program for the calculation, assessment and prognosis of noise exposure.

Noise criteria

Project specific construction noise criteria

The ICNG (DECC 2009) provides guidance for assessing construction noise. The ICNG outlines standard hours for construction activities as Monday to Friday: 7 am to 6 pm, Saturday: 8 am to 1 pm and no work on Sundays or public holidays.

The ICNG acknowledges that the following activities have justification to be undertaken outside the recommended standard construction hours assuming that all reasonable and feasible mitigation measures are implemented to minimise the impacts to the surrounding sensitive land uses:


The delivery of oversized plant or structures that police or other authorities determine to require special arrangements to transport along public roads

Emergency work to avoid the loss of life or damage to property, or to prevent environmental harm

Works where a proponent demonstrates and justifies a need to operate outside the recommended standard construction hours

Works which maintain noise levels at receivers to below the noise management levels outside of the recommended standard construction hours.

Table 6.4 and Table 6.5 detail the ICNG construction noise management levels at sensitive land uses and residences near the proposal, where:

The noise affected noise management level represents the point above which there may be some community reaction to noise. Where the predicted or measured LAeq(15min) is greater than the noise affected level, the proponent should apply all feasible and reasonable work practices to meet the noise affected level. The proponent should also inform all potentially impacted residents of the nature of works to be carried out, the expected noise levels and duration, as well as contact details

The highly noise affected level represents the point above which there may be strong community reaction to noise. Where noise is above this level, the relevant authority (consent, determining or regulatory) may require respite periods by restricting the hours that the very noisy activities can occur, taking into account:

– times identified by the community when they are less sensitive to noise (such as before and after school for works near schools, or mid-morning or mid-afternoon for works near residences)

– if the community is prepared to accept a longer period of construction in exchange for restrictions on construction times.

Traffic noise criteria

The RNP provides traffic noise target levels for residential receivers in the vicinity of existing roads (Table 6.7). These levels are applied to construction works to identify potential impacts as a result of noise produced by construction traffic and the potential for reasonable and feasible mitigation measures to be applied.

If road traffic noise increases as a result of construction work lies within 2 dB(A) of current levels then the objectives of the RNP are met and no specific mitigation measures would be required.

Vibration criteria

Human comfort

6.5.2 Human comfort

Vibration has been assessed based on the criteria in Assessing Vibration: a technical guideline. British Standard (BS) 6472 – 1992, Guide to Evaluation of Human Exposure to Vibration in Buildings (1 Hz to 80 Hz) is recognised by the guideline as the preferred standard for assessing the ‘human comfort criteria’.

Typically, construction activities generate ground vibration of an intermittent nature. Intermittent vibration is assessed using the vibration dose value. Acceptable values of vibration dose are presented in Table 6.9 for sensitive receivers.

Whilst the assessment of response to vibration in BS 6472-1:1992 is based on vibration dose value and weighted acceleration, for construction related vibration, it is considered more appropriate to provide guidance in terms of a peak value, since this parameter is likely to be more routinely measured based on the more usual concern over potential building damage.

Humans are capable of detecting vibration at levels which are well below those causing risk of damage to a building. The degrees of perception for humans are suggested by the vibration level categories given in BS 5228.2 – 2009, Code of Practice Part 2 Vibration for noise and vibration on construction and open sites – Part 2: Vibration, as shown below in Table 6.10.

Table 6.9: Human comfort intermittent vibration limits (BS 6472-1992)

Table 6.10: Guidance on effects of vibration levels for human comfort

(BS 5228.2 – 2009)

Vibration level Effect

0.14 mm/s Vibration might be just perceptible in the most sensitive situations for most vibration frequencies associated with construction.

0.3 mm/s Vibration might be just perceptible in residential environments.

1.0 mm/s It is likely that vibration at this level in residential environments will cause complaints, but can be tolerated if prior warning and explanation has been given to residents.

10 mm/s Vibration is likely to be intolerable for any more than a very brief exposure.

Cosmetic damage

BS 7385 Part 2– 1993 Evaluation and measurement for vibration in buildings Part 2 provides criteria to assess the effects of transient vibration on structures. DIN4150 has criteria for particular reference for heritage structures however note BS 7385 states the following:

“A building of historical value should not (unless it is structurally unsound) be assumed to be more sensitive.”

Important buildings which are difficult to repair (such as heritage buildings) may require special consideration on a case-by-case basis particularly if a dilapidation report indicates they are structurally unsound. The DIN vibration criteria is presented below in Table 6.11 for consideration for the case of any identified structurally unsound buildings.

The proposal is located to the north-east of Lockhart, south of Brookong Creek. The land use surrounding the site is rural, with residential receivers located to the south and south-west.

Construction noise and vibration impacts have been assessed for 101 sensitive receivers (see Figure 6-5). Other sensitive receivers (such as educational institutes, places of worship and hospitals) within Lockhart are located over one kilometre from the construction zone. These receivers are also acoustically shielded by preceding rows of houses. The only non-residential receiver considered in the assessment is a Church on Ferrier Street.


Rating background levels and ambient noise levels are summarised in Table 6.12. The ambient noise levels are typical of a rural area with low background noise levels and few sources of artificial noise.

Noise

Construction noise levels have been predicted during standard construction hours at modelled sensitive receivers for each construction scenario. Impacts to sensitive receivers have the potential to occur where sensitive receivers experience noise higher than the relevant construction noise management level.

The predicted number of receivers exceeding the relevant construction noise management levels is presented in Table 6.13.

Table 6.13 Number of receivers exceeding the construction noise

management levels

Construction noise management level

Backhoe Excavator Front end loader Grader Roller Scraper Truck/water cart

40 (standard hours) 50 68 100 90 74 101 68

The results indicate that, without mitigation, construction noise may exceed the noise management levels at sensitive receivers during standard construction hours. The worst affected receivers lie along Galore Street, with a direct line of sight to the construction zone.

The highly noise affected criteria is not predicted to be exceeded at any identified sensitive receivers.

For the noisiest construction equipment (scraper), the above noise impact zones have been mapped and are shown in Figure 6-6.

The magnitude of off-site noise impact will be dependent upon a number of factors including the intensity and location of activities, the type of equipment used, the background noise levels during the construction period, the prevailing weather conditions and the movement of construction equipment within the construction corridor.

Vibration

Structural damage

With consideration to the building damage criteria for typical buildings, the expected magnitude of ground vibrations should not be sufficient to cause damage to standard buildings within 12 metres of the works or heritage buildings within 24 metres of the works. The impact will depend on the size of equipment used.

No standard dwellings or heritage structures have been identified within the safe working buffer distances. Specific structural damage vibration mitigation measures are not required for the proposal.

Human comfort

The nearest residential receivers are over 50 metres from the proposal area. Human comfort impacts from the proposal are not anticipated for vibratory rollers up to six tonnes. Specific vibration mitigation measures are not required for the proposal.

Construction noiseClearly audibleModerately intrusiveHighly intrusive




Construction noise and vibration impacts

A noise and vibration management plan will be prepared as a sub plan to the construction environmental management plan. The plan will include proposed environmental control measures for all high noise and vibration generating activities

A community relations program would be prepared as part of the CEMP to ensure that sensitive receivers are informed on the progress of the construction works. Notifications would be undertaken in accordance with the community liaison program.

Pre-construction

Contractor and Council

Construction noise from inappropriate practices

Inductions for the work crew would include the specific noise issues and mitigation measures required for the site. The induction would include:

– all relevant project specific and standard noise mitigation measures

– relevant approval conditions

– permissible hours of work

– location of nearest sensitive receivers

– construction employee parking areas

– designated loading/ unloading areas and procedures

– site opening/closing times (including deliveries)

– behavioural practices including:

– avoiding the use of outdoor radios when working outside the recommended standard hours

– avoiding shouting and slamming doors

– where practical, operating machines at low speed or power and switching off when not being used rather than left idling for prolonged periods

– minimising reversing alarms

Avoiding dropping materials from height and avoiding metal to metal contact on material.

Construction

Contractor

Construction noise impacts

Where the predicted and/or measured construction noise is greater than the noise affected level, works would be conducted in accordance with the ICNG and all reasonable and feasible practices would be undertaken to minimise noise

Construction

Contractor



Site setup and dismantling would occur during standard work hours, reducing noise impacts to sensitive receivers where possible. The site setup would seek to maximise the distance between plant and equipment and any residences and other noise sensitive receivers where practicable. For example, vehicle movements and generator storage would be located as far as possible from residences

Use quieter noise emitting construction methods where practicable

Machines found to produce excess noise compared to industry best practice would be removed from the site or stood down until repairs or modifications can be made

Ensure that truck engine brakes usage is minimised when entering or leaving the work sites or work areas adjacent to residential properties and on construction traffic routes

Any noise complaints would be addressed immediately in accordance with a standard resolution procedure. Property owners/occupiers potentially impacted by the construction works would be informed in advance of the proposed work and provided a contact phone number for any complaints or concerns during the construction period.

6.6 Air quality


Air quality

The proposal site is located in an urban, semi-rural setting just off the Lockhart-Collingullie Road, adjacent to properties used for agriculture. Sources of air pollution in the study area are likely to include:

Emissions from vehicles on local roads

Dust from vehicles travelling on unsealed roads

Dust from agricultural activities

Smoke from paddock stubble burn-off in agricultural areas, as well as from wood fires.

Search results from the national pollutant inventory managed by DotEE (2017c) indicate there are no industrial facilities in the local government area.

The nearest industrial facilities to emit pollutants are in Urana and Uranquinty. None of these facilities are located in or near the study area. The closest facilities are the Uranquinty Power Station in the east, approximately 45 kilometres from the proposed levee bank site and the


Butherwah Urana Piggery to the south east, approximately 42 kilometres from the proposal site. The most commonly reported atmospheric emissions are:

Total volatile organic compounds

Ammonia

Sulphur dioxide

Carbon monoxide

Oxides of nitrogen

Particulate matter 10.0 micrometre.

Sensitive receivers

Sensitive receivers with the potential to be affected by air quality impacts during construction of the proposal include residents near the proposal site. A number of residences are located along Galore Street, approximately 80 metres from the proposed levee bank (see Figure 1-1).


Construction

During construction the following activities would potentially result in air quality impacts:

Clearing of groundcover vegetation

Earthworks

Stripping and stocking topsoil

Transport and handling of soils and materials.

Use of construction vehicles, generating exhaust fumes.

Potential air quality impacts during construction would predominantly be from the generation of dust. Dust generation could result in health impacts to nearby receivers.

Given the close distances of the proposed earthworks to sensitive receivers, it is expected the proposal would cause temporary air quality impacts at residences.

Dust could be generated by construction vehicles accessing the proposal site along the unsealed access tracks in the Town Common and TSR. The impacts of dust generation would be short-term, during the construction phase only and would be controlled using the safeguards detailed in section 6.6.3.

Machinery and other construction vehicles would emit exhaust fumes. The impact of these emissions would be temporary in nature and limited to the construction phase.

Overall, potential air quality impacts during construction would be moderate and short-term.



General air quality impacts

Construction activities will be managed to minimise the emission of dust, smoke, and other substances.

Construction

Contractor

Dust Air quality impacts relating to dust generated by construction vehicles will be monitored

Construction



Exposed surfaces will be watered regularly to minimise dust emissions, if required

During periods of high winds, dust generating activities will cease

Stabilisation of disturbed surfaces will take place as soon as practicable

Areas that may generate dust will be managed to suppress dust emissions

Measures such as road watering will be carried out to minimise dust impacts for residences, if required.

Contractor

Other emissions

Plant and machinery will be turned off when not in use as much as possible and will be fitted with emission control devices complying with Australian Design Standards

Construction plant and equipment will be maintained in a good working condition in order to limit impacts on air quality

No burning of any materials will occur

During transportation, loads will be adequately covered.

Construction

Contractor

6.7 Landscape and visual


The landscape character of the study area is generally defined by urban development to the south and rural properties used for agriculture to the north, east and west. The study area is located on the floodplain of Brookong Creek, and is therefore generally flat, with the exception of the dam structures.

There is remnant native woodland vegetation north of the Government Dam proposal site and scattered paddock trees throughout the site. Mixed age remnant woodland is present in the TSR. Native woodland in the study area provides an aesthetic visual character.

Key receivers in the study area include residences along Galore Street and surrounding streets. The proposal site would also be visible from Lockhart – Collingullie Road (see Figure 1-1).


Construction

Visual impacts during construction would generally be associated with:

Plant and equipment

Earthworks

Establishment of the site compound and stockpile site.


These have the potential to temporarily affect views for residents and local road users.

Residents would be affected by views of the construction of the proposal, including earthworks, construction plant and equipment and the compound and stockpile site.

The visual impacts of construction works would be temporary and relatively small-scale. It is anticipated that reinstatement of disturbed areas would reduce the visual impacts in the short to medium term after construction.

Operation

The construction of proposal would potentially impact upon visual amenity, particularly for residents along Galore Street that run along the Government Dam site. The proposed levee would add a new feature to the site and remain visible for residents during operation, with a height of about two metres. It is unlikely, however, that the levee would cause any substantial obstruction of existing views due to the presence of the existing dam structure.



Visual impacts of proposal

The footprint for construction works will be kept to a minimum to minimise earthworks and maintain existing groundcover vegetation wherever possible

Sites disturbed by earthworks will be rehabilitated as soon as possible after construction.


Council and contractor

Visual impacts of construction works

The work site will be left in a tidy manner at the end of each work day.

6.8 Aboriginal heritage

Aboriginal heritage assessments for the proposal was completed by Mark Saddler (2016 and 2017). The reports are included in Appendix H.

6.8.1 Methodology

Review of existing information A desktop search of the following databases was conducted:

OEH Aboriginal Heritage Information Management System (AHIMS). Searches of the AHIMS database included:

– Search completed on 13 December 2016 with a buffer of 200 metres, centred on the levee upgrade portion of the proposal site

– An extensive search of the site was also completed on 15 December 2015.

Field survey

The Government Dam and TSR study area was surveyed by Mark Saddler on 22 December 2016 and 9 March 2017 respectively. The survey included an inspection of the area surrounding the proposed levee location for objects of potential Aboriginal cultural heritage value.


All mature trees old enough to bear cultural scarring and all ground surface exposures were inspected. Notes on the vegetation, disturbance, land-use and archaeological potential were made within the survey area.


Lockhart township falls on the southern boundary of the Wiradjuri Country. Watercourses are likely to have formed an important focus for traditional Aboriginal activities. Brookong Creek, which runs through the town, may have been a landscape feature of significance for the local Aboriginal community, providing opportunities for fishing and hunting.

The archaeology of the Lockhart Shire is part of a distinctive pattern found on the Riverine Plain. Artefacts that have been found on the Riverine Plain include fired clay balls and stone tools. Scarred trees are widespread at various locations throughout the shire and burials are also common (LSC 2012).

The AHIMS extensive search conducted identified four sites located within the Town Common, in the vicinity of the proposal site, comprising the following (see Figure 6-7):

Two scarred trees

A mound (oven)

An open camp site.

The subsequent site survey identified an additional eight Aboriginal sites, all comprising modified / scarred trees (see Figure 6-7). The survey also re-recorded the two scarred trees and the mound (oven) and open camp site identified in the AHIMS extensive search. The mound and open camp site were both recorded as earth mounds.

There is some ambiguity in the GPS coordinate locations of the Aboriginal sites recorded during the recent survey, with the AHIMS sites identified during the extensive search. All records can be seen on Figure 6-7.

The area has been heavily impacted by cattle and machinery, which has damaged previously recorded Aboriginal sites.

The Lockhart Town Common also has an Aboriginal Land Claim lodged against it.

Proposal site



The study area contains 12 Aboriginal sites in total. None of these sites are located within the footprint of the proposed levee, however, the proposal has the potential to damage these sites during construction activities such as vehicle and machinery movement and placement of the stockpile and compound site.

The proposal also has the potential to impact on land subject to an Aboriginal Land Claim. The claim is unlikely to be resolved prior to construction commencing, however, an approval to construct is being sought as an exemption due to the high priority of the proposal.



Impacts to known Aboriginal sites

All previously recorded Aboriginal sites within 40 metres of the proposal site would be identified on site by an Aboriginal heritage advisor and fenced prior to construction commencing

All site staff would be informed of the location and significance of the Aboriginal heritage sites prior to construction commencing

Should the footprint of the proposal be likely to impact on an item of Aboriginal heritage, the footprint would be altered in order to avoid the item

The stockpile and compound site would be located at least 20 metres away from Aboriginal sites.

Pre-construction

Potential impacts to unexpected finds

In the event of an unexpected find of an Aboriginal heritage item (or suspected item), all works in the vicinity of the find must cease and the site supervisor will be contacted immediately for advice on how to proceed

If the origin of the find cannot be determined quickly, or if it is determined that the find is of Aboriginal origin, immediately notify the following authorities or personnel of the discovery:

– OEH (Queanbeyan Office): ph. 131 555 or (02) 9995 5555.

– Wagga Wagga Local Aboriginal Land Council (LALC): ph. (02) 6921 4095.

Facilitate, in co-operation with the appropriate authorities and Wagga Wagga LALC:

– The recording and assessment of the finds

Construction




– Fulfilling any legal constraints arising from the find(s). This will include complying with OEH directions

– The development and conduct of appropriate management strategies. Strategies will depend on Aboriginal consultation and the assessment of the significance of the find(s).

Where the find(s) are determined to be Aboriginal objects as defined by the NPW Act, any re-commencement of construction related ground surface disturbance may only resume in the area of the find(s) following compliance with any consequential legal requirements and gaining written approval from OEH (as required).

Potential impacts to unexpected human remains

Cease all ground surface disturbance in the area of the find(s) immediately by notifying machinery operators in the immediate vicinity of the find(s). Also avoid touching the discovered remains

Inform the site supervisor as soon as possible to organise for a qualified professional opinion (usually the police in the first instance)

Create a buffer zone of 50 metres by 50 metres around the find spot. No authorised entry or earth disturbance will be allowed until the discovery has been assessed.

Construction contractor and Council

6.9 Non-Aboriginal heritage

6.9.1 Methodology

Heritage databases were searched on 8 January 2017 to identify any heritage items recorded in the study area, including the following:

Australian Heritage database, for items and places of national heritage significance.

NSW State Heritage Inventory, for items and places of State heritage significance.

Heritage Schedule 5 of the Lockhart LEP for zoning and local heritage information.


History of European settlement

The following information is sourced from Lockhart Shire Council (2015).

The Lockhart area was first visited by Europeans when the party of explorers led by Charles Sturt travelled through the area in 1829, during their exploration of the Murrumbidgee and Murray Rivers. Settlement followed soon after. Historic settlement in the study area is closely related to the pastoral and agriculture activity that has characterised the region’s economy.


Brookong, Grubben, Mittagong and Urangeline Stations once controlled major areas of the Lockhart district. Brookong Station, with more than 480,000 acres, was the scene of a famous shearers strike in 1888, which paved the way for the trade union movement.

Of the large shearing sheds which once dominated these stations, only the Urangeline woolshed stands today in its entirety as a reminder of the days of large stations and Australian reliance on the wool industry.

The Lands Department subdivided substantial areas of former leasehold land into small holdings of about 200 hectares or a little more. It was not long before most of the station owners also subdivided substantial areas of freehold land into small blocks and by 1915 the bulk of the land within Lockhart Shire was held by small settlers. The town of Lockhart, which was to become Shire Headquarters, was only surveyed in 1897.

When the Lockhart Shire was formed in 1906 there were no lengths of constructed road. Stone crossings had been constructed at some creek crossings. There were dilapidated timber bridges across some larger creeks and there may have been short, scattered sections of formed roads. Most of the older roads were just well worn tracks and, with the division of the large stations into farms, generally from 200 to 300 hectares, an extensive network of roads was required to give access to the individual holdings.

Heritage sites

One listed heritage item is located in the study area; St Mary’s Catholic Church, which is located in Ferrier Street, south-west of the proposal (see database searches in Appendix E).

The Lockhart Conservation Area is located just outside of the study area to the south-west of the proposal, covering an area of Green Street. This area was listed because of its continuous lines of veranda posts on both sides of the main street in the central area, making it a good example of the turn of the century architecture.


No sites with the potential to be of non-Aboriginal heritage significance were identified during field investigations. It is unlikely that the proposal would cause any impacts to items of non-Aboriginal heritage.



Potential impacts to unexpected finds

In the event of an unexpected find of a non-Aboriginal heritage item (or suspected item), all works in the vicinity of the find must cease and the site supervisor will be contacted immediately for advice on how to proceed

Works will not recommence until the heritage value and associated protection and any approval requirements have been determined

Council will notify OEH if any item (or suspected item) of non-Aboriginal heritage is found during construction to determine the appropriate course of action.

Contractor


6.10 Traffic access


The proposal site is located adjacent to Galore Street and Lockhart – Collingullie Road. Figure 1-1 shows the location of roads in relation to the proposal site.


Construction of the proposal would be undertaken so that impacts to traffic would be minimised as much as possible.

Construction access to the proposal site would be via Lockhart – Collingullie Road. The berm closing off the eastern end of Galore Street would be removed to provide vehicle access to the Government Dam site and to allow for construction of the levee. Vehicle movements from the Treasure Street spoil site to the proposal site are anticipated to be via Brookong Street and East Street then Lockhart – Collingullie Road.

The proposal would generate a number of heavy vehicle movements through the transport of machinery, fuel, general provisions and materials across the duration of the project. The number of heavy vehicle movements required to transport spoil from Treasure Street to the proposal site would be approximately 100, with two trucks carting about 50 loads of spoil each over the duration of the construction period.


This number of vehicle movements generated by the proposal would be unlikely to significantly affect traffic on local roads.

Traffic controls would be put in place for works along Lockhart – Collingullie Road. During the construction period, traffic would be restricted to one lane or alternatively redirected onto a side track in the road reserve on the southern side of the road. This would be determined during construction. The proposal would be unlikely to cause any significant disruption to traffic.

Property access

There would be changes to the property access for the Town Common during construction and operation. The alignment of the levee would follow the existing access track within the Government Dam site where the gate access is located. The gate would be removed during the construction period and reinstated about 1.5 metres to the west of the toe of the new levee. All other access would be maintained throughout construction.



Construction impacts to traffic

A traffic management plan would be prepared in accordance with the Australian Standard 1742.3-2002: Manual of Uniform Traffic Control Devices and the NSW Roads and Maritime Services ‘QA Specification G10 Traffic Control at Worksites’

The traffic management plan would include measures to provide safe access points to work areas from the adjacent road network, safety barriers where necessary, temporary speed restrictions when

necessary, specific controls for partial road closures and changed road conditions, adequate sight distances and prominent warning signage. The plan would also include measures to restrict public access to the proposal site.

Construction impacts to traffic and property access

The traffic management plan would be implemented during construction

All fences and gates would be reinstated to the same standard as existing prior to completion of the proposal.

6.11 Socio-economic

6.11.1 Existing Environment

The town of Lockhart is located about 60 kilometres south-west of Wagga Wagga. The town provides essential services, such as medical and community facilities, shopping and schools.

2016 Census data

The 2011 Census (ABS 2012) provides the following core demographic data about the Lockhart LGA:

At the time of the 2011 Census there were 2,998 people in the Lockhart LGA

The number of dwellings was 1,334, with an average household size of 2.5

The proportion of people aged 19 years or under was 25.6 per cent

The proportion of people aged 60 years or older was 19.6 per cent

The median weekly household income was $868

The proportion of households with two motor vehicles was 36.1 per cent

People of Australian Aboriginal descent comprised 2.7 per cent of the population.

The top employment industries for the Lockhart LGA (ABS 2011) are provided in Table 6.14.

Table 6.14: Top employment industries for the Lockhart LGA

Industry Number employed Percentage of people employed

Managers 455 34.1

Technical and trades 151 11.3

Professionals 148 11.1

Clerical 141 10.6

Labourers 120 9.0


The area surrounding Lockhart mainly comprises rural land use. In 2016 the agriculture, forestry and fishing industry employed 381 people, or 28.6 per cent of all people employed in the Lockhart LGA (ABS 2011).

Land uses in the study area are listed in section 6.4. Land use in the study area is characterised by urban development to the south and agricultural land use, including grazing and cropping to the north, east and west.

Flooding

Community consultation was an important element of both the flood study and FRMP completed by WMAwater (2014a, 2014b). Consultation was undertaken to assess the flood experience of the community, gather data and keep the community informed of the progress of potential mitigation and management measures proposed. Following the 2010 and 2012 floods, questionnaire distribution and interviews were also conducted by the State Emergency Service.

Flood events in the town have both high economic and social impacts, with damage being caused to numerous residences, businesses and properties in flood prone areas. The March 2012 event is the largest flood event in Lockhart’s history, reaching 2.1 metres on the Green Street causeway gauge. About 67 houses and 31 commercial/public sector building were flooded above floor level.

Hydraulic modelling indicates that flooding along Galore Street due to creek breakouts on the southern bank of Lockhart Government Dam is possible for events as small as the five year ARI. For the one per cent AEP flood, up to 18 homes are likely to become inundated in addition to significant flooding of property lots in the region. This event would inundate much of Lockhart with overland flows from the Milbrulong region likely to cause flooding in the regions bordering East Street and Brookong Street. This would restrict access to the town making Lockhart a high flood island.

High risk regions are situated bordering Brookong Creek, Urana Street, Galore Street, Ferrier Street and lower Green Street. Urana Street experiences the most dangerous flood characteristics in the region with deep, high velocity flows.


During construction there would be a potential reduction in amenity for rural residences as a result of construction activities. Potential impacts on amenity have been assessed in the following sections of the REF:

Land use and property (section 6.4)

Noise and vibration (section 6.5)

Air quality (section 6.6)

Visual (section 6.7).

Some land acquisition would be required, which has the potential to affect one private land holder and Crown Land, although this is expected to be minimal (see section 6.4).

Beneficial impacts

The proposal would provide an enhanced level of flood protection for the people of Lockhart, properties and infrastructure. There would be reductions in peak flood level exceeding 0.3 metres in some areas and many areas would no longer experience flooding. Most of Lockhart would see about a 0.1 metre reduction in peak flood level. The average annual damage for residential and commercial properties would be reduced by $164,000 with these combined mitigation measures. About 91 percent of the reduction in damages in due to reduced flood


affectation of residential properties (WMAwater 2014a). The Government Dam levee alone is expected to provide a $140,000 reduction in average annual damage.



General impacts to properties

Potentially affected property owners will be contacted before the commencement of works. Residents will be notified via door knocks or letter box drops providing information on the proposed works, working hours and a contact name and number should any complaints wish to be registered.

Council

6.12 Waste management

6.12.1 Policy setting

Council is committed to ensuring responsible management of unavoidable waste and to promoting the reuse of such waste through appropriate measures. This is done in accordance with the resource management hierarchy principles contained in the Waste Avoidance and Resource Recovery Act 2001. The resource management hierarchy principles in order of priority as outlined in the Waste Avoidance and Resource Recovery Act 2001 are:

Avoidance of unnecessary resource consumption

Resource recovery (including reuse, reprocessing, recycling and energy recovery)

Diversion of Green waste, metal waste and E-waste

Disposal

Chemclear implemented in 2017 to collect unwanted agricultural chemicals.

By adopting the above principles, Council encourages the most efficient use of resources and reduces cost and environmental harm.


The proposal is unlikely to generate large quantities of waste. Waste would potentially be generated from the following sources, some of which would be recycled or reused:

Green waste from vegetation clearing (native and introduced vegetation). Noxious weed material would be separated from native green waste

Chemicals and oils

Waste water from wash-down and bunded areas

Excess construction materials

Redundant erosion and sediment controls

Paper and office waste from site and management facilities

General waste from staff (lunch packaging etc).

The potential to reuse materials would be investigated during detailed design. The largest quantity of waste expected to be produced would be from excavation activities.


Liquid and solid waste would be removed by tanker or truck and disposed of off-site at a facility that is licensed and able to accept those wastes for storage, reuse or disposal. Fuel and chemical storage areas would be bunded and protected in accordance with the specifications set out by OEH and WorkCover.

Any spoil material that cannot be used on site would be classified in accordance with the ‘Waste Classification Guidelines’ (EPA 2014) and disposed of at an approved materials recycling or waste disposal facility.

Materials not reused would be removed to a licensed or approved facility. The impacts of waste generation at the site are considered to be low, and would be minimised.



General waste impacts

A waste management plan will be included in the CEMP.

Contractor

General waste impacts

Resource management hierarchy principles will be followed:

– Avoid unnecessary resource consumption as a priority

– Recover resources as far as is practicable (including reuse of materials, reprocessing, and recycling and energy recovery)

– Disposal is undertaken as a last resort (in accordance with the Waste Avoidance and Resource Recovery Act 2001).

Site inductions will be undertaken (and recorded) by a site supervisor for all staff, to provide a thorough knowledge of all key environmental/safety issues, including waste disposal protocols

Wastes will be managed and classified in accordance with the ‘Waste Classification Guidelines’ (EPA 2014) and managed in accordance with the POEO Act

All waste will be disposed of at appropriately approved and licensed facilities

Garbage receptacles will be provided and recycling of materials encouraged. Rubbish will be transported to an appropriate waste disposal facility.

Where appropriate, excess materials will be disposed of according to the following (in order):

– Use remaining materials as directed by Council and Contractor

– Disposal at an approved materials recycling or waste disposal facility

– As otherwise provided for by the relevant waste legislation.

Waste material will not be left on site once the works have been completed.

6.13 Climate change

6.13.1 Policy setting

Climate change refers to the warming temperatures and altered climatic conditions associated with the concentration of greenhouse gases in the atmosphere. There is a need to understand climate change and the effect it could have on all existing and potential new projects and infrastructure. In NSW, responses to climate change are provided in various policy and guideline documents such as the NSW Greenhouse Plan (NSW Government 2005b).

The Intergovernmental Panel on Climate Change produces global climate change projections. In Australia both the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Bureau of Meteorology (BOM) have produced regional downscaled projections for Australia. In 2008 the NSW Government published refined climate change projections for each region in NSW. This work was carried out by researchers at the Climate Change Research Centre, University of New South Wales.


Existing climate

The Lockhart area receives an average annual rainfall of 442.2 millimetres. Rainfall is spread evenly throughout the year with a maximum in June (BOM 2017).

The mean maximum temperature for Urana, the closest weather station, is 23.7 degrees celsius. The mean minimum temperature is 9.5 degrees celsius (BOM 2017).

Climate change

The former Department of Environment, Climate Change and Water (now OEH), in partnership with the Climate Change Research Centre at the University of New South Wales, developed regional climate projections for NSW based on preliminary analyses of global modelling data. The projections have been developed for ‘State Plan regions’ throughout NSW (OEH 2014). The proposal occurs in the Murray Murrumbidgee Region, which includes the NSW side of the Murray River, as well as the Murrumbidgee and Lachlan Rivers.

By 2039, annual rainfall in the Murray Murrumbidgee Region is projected to increase in summer and autumn and decrease in spring. Severe fire weather is projected to increase across the region during spring and summer, and decrease during autumn.

Maximum temperatures are projected to increase in the near future by 0.4 to one degrees celsius and in the far future by 1.5 to 2.5 degrees celsius. The number of hot days is projected to increase, while the number of cold nights will decrease.



Potential impacts of climate change on the proposal

Climate change impacts on rainfall are likely to alter flooding intensity; however peak flood levels are generally relatively insensitive to increases in rainfall. Locations that are directly affected by flooding from Brookong Creek are the most sensitive to predicted climate change impacts, with increased peak levels of over 0.3 metres experiences upstream of the Brookong Creek bridges for a 30 percent increase in rainfall (WMAwater 2014a).

Fluctuations in rainfall and temperature caused by climate change are expected to be variable in nature. There is the potential for climate change to cause short-term and long-term impacts. Impacts could therefore occur during both the construction and operation phases of the proposal.

Construction

Increases in temperatures may reduce work capacity and increase the risk of heat stress for site workers.

There may be impacts to various construction activities from climate change, such as increased temperatures interfering with the laying concrete.

There may be an increase in extreme weather events, such as intense rainfall interfering with construction timeframes or dry, hot weather conducive to generation of dust.

Increased summer rainfall may result in increased flooding and erosion risks at the site and associated sediment loss.

Operation

Increases in temperature may affect the integrity of the levee and other aspects of the proposal in the long-term. This may occur either directly or through evaporative changes and changes in soil moisture content and soil instability, which in the long term may affect structures.

Changes in rainfall intensity may result in the following impacts in the long term:

Increased potential for localised flooding

Drainage and stormwater impacts

Changes to flora and fauna species and distribution, including pest and weed species

Erosion impacts, resulting in sediment loss from the site

Watercourse impacts, including changes to channel structure and other characteristics near the proposal site resulting from changed hydrological conditions.

Potential impacts of the proposal on climate change

Construction

Impacts of the proposal on climate change during construction would include the release of the following greenhouse gases:

Carbon dioxide may be generated from land clearing (decomposition of cleared vegetation)

Carbon dioxide and nitrous oxide would be generated from liquid fuel use in plant and vehicles (diesel, petrol) during construction and disposal and transport of materials

Methane would be released from landfilling any carbon based waste


Various greenhouse gas emissions would be associated with the extraction and production of materials used in the construction of the levee upgrade.

Operation

Maintenance activities would be undertaken along the levee as necessary. Maintenance activities are expected to be infrequent and there would therefore be a negligible change in vehicle emissions resulting from maintenance activities for the proposal.



Flooding from extreme rainfall events

Detailed design, including drainage requirements, would take into consideration the effect of climate change on the proposal.

Council

Greenhouse emissions

Investigations into opportunities for reducing greenhouse emissions during construction and operation of the proposal would be undertaken during the detailed design and construction planning phase.

Investigation of alternative fuels and power sources would be undertaken and implemented, where appropriate

Energy efficiency and related carbon emissions of vehicle and plant equipment would be considered, where possible

Material and waste supply and departure scheduling would be undertaken to optimise full loads and minimise required vehicle trips

Clearing of vegetation would be minimised where feasible.

Construction

Contractor


6.14 Demands on resources


The proposal would require the use of a number of resources, including:

Resources associated with the operation of construction machinery, and motor vehicles (this includes a variety of resources, the major one being diesel and petrol)

Fill required to meet design levels, which would be obtained from the proposal site and the Treasure Street spoil site

Other materials required for the construction of various components of the proposal including culverts and pipes

Material required for road surfaces and infrastructure (road base, paints, solvents, asphalt, spray seal, sand, concrete, aggregate, steel etc)

Construction water (for concrete and dust suppression). This would be likely sourced from the local potable supply.

The quantities of materials required for the proposal are detailed in section 3.3.3.

The materials required during the proposed construction works are not currently restricted resources. However, materials such as metals and fuels are considered non-renewable and would be used conservatively.

Materials would be sourced from local and commercial suppliers, where possible. Excess materials would be disposed of in accordance with safeguards and management measures outlined in section 6.14.2.



Resource consumption

The procurement of materials would be limited to the quantities required for the proposal

Procurement would endeavour to use materials and products with a recycled content where that material or product is cost and performance effective.

Construction

Contractor

6.15 Cumulative impacts


Developments in the locality with which the proposal has the potential to have cumulative impacts include:

Agricultural development, including grazing and cropping, which has transformed the land in the study area over the last 170 years

Maintenance of linear infrastructure projects including roads, powerlines and services that have been constructed in the study area and locality.

There are no other known major developments occurring concurrently or planned in the locality.



The developments outlined in section 6.15.1 above would be likely to have cumulative impacts in relation to ecology (see section 6.1.3), soils and water quality, visual amenity and air quality impacts.

Disturbance associated with the proposal could facilitate the spread of weeds in the study area, which is already heavily influenced by the spread of weeds associated with agricultural development.

The proposal would be likely to have relatively minor cumulative impacts in relation to these factors.


It is considered that the potential for adverse cumulative impacts is most effectively addressed by the application of the individual safeguards recommended throughout the REF. a summary of all recommended safeguards is in Table 6.15.

6.16 Summary of adverse effects

The main adverse effects of the proposal would include:

Removal of about 500 square metres of grassland that forms the threatened ecological community Weeping Myall Woodland

Removal of about 17 native trees (one Weeping Myall, four Grey Box, six planted Wattles, six planted Belah trees)

Potential for soil erosion and water quality impacts during construction of the levee bank, channel and berm

Potential construction noise impacts on nearby residences

Potential for a reduction in air quality caused by the generation of dust during construction

Other changes in amenity and environmental risks including visual impacts and waste


Table 6.15: Summary of safeguards and management measures.


Biodiversity - Loss of native vegetation habitat


Pre-clearing surveys will be completed to establish exclusion zones and on-ground identification of specific habitat features to be retained (e.g. hollow-bearing trees)

Temporary exclusion fencing will be erected to prevent encroachment and clearing of remnant vegetation beyond the construction footprint

Stockpiles of construction materials, fill or vegetation will be restricted to existing cleared areas and not within areas of adjoining native vegetation

Where possible, the detailed design of the proposal will incorporate measures to minimise vegetation removal, particularly Weeping Myall Woodland


Removal of native vegetation will be minimised wherever possible

Pruning or lopping of limbs will be conducted in preference to tree removal wherever possible.

7. Environmental management

This chapter describes how the proposal would be managed to reduce potential environmental impacts throughout construction and operation. A framework for managing the potential impacts is provided with reference to environmental management plans. The licence and/or approval requirements required before construction are identified.

7.1 Environmental management plan

A number of safeguards and management measures have been identified in order to minimise adverse environmental impacts, including social impacts, which could potentially arise as a result of the proposal. Should the proposal proceed, these management measures would be applied during the construction of the proposal.

A construction environmental management plan (CEMP) and relevant environmental sub-plans would be prepared to describe safeguards and management measures identified. These plans would provide a framework for establishing how these measures would be implemented and who would be responsible for their implementation.

The plans would be prepared before the construction of the proposal. The CEMP would be a working document, subject to ongoing change and updated as necessary to respond to specific requirements.

7.2 Licensing and approvals

The proposal would require the following approvals:

Table 7.1: Summary of licensing and approval required

Requirement Timing Approval is required from the Aboriginal Lands Council for work in the Government Dam site that has an Aboriginal Land Claim on it.

Pre-construction

Under section 155 (1) of the Crown Lands Act 1989 consent would be required for works within Crown land that are not located within an existing easement. Consent would need to be obtained from the Local Land Services for the TSR and the Common Trust for the Town Common.

Consent has been granted from the Local Land Services for work in the TSR. Consent has been granted from the Common Trust for work in the Town Common


8. Conclusion

This chapter provides the justification for the proposal taking into account its biophysical, social and economic impacts, the suitability of the site and whether or not the proposal is in the public interest. The proposal is also considered in the context of the objectives of the EP&A Act, including the principles of ecologically sustainable development as defined in schedule 2 of the Environmental Planning and Assessment Regulation 2000.

8.1 Justification

The proposal is required to provide an enhanced level of flood protection for residences south of Brookong Creek, in Lockhart. The Government Dam levee is based on a design which achieves a levee crest with 500 millimetres of freeboard above the 100 year ARI flood level. In flood events, the levee will provide protection to the residential properties on the south side of the levee. Combined with the channel and berm east of Lockhart – Collingullie Road there would be reductions in peak flood level exceeding 0.3 metres in some areas and many areas would no longer experience flooding. The average annual damage caused from flooding would also be decreased

There would be a number of adverse environmental impacts as a consequence of the proposal. These impacts are mostly considered short-term, being directly related to construction activities.

The primary impacts during construction include:

Removal of about 500 square metres of grassland that forms a threatened ecological community (Weeping Myall Woodland)

Removal of about 17 native trees

Potential for soil erosion and water quality impacts during construction of the levee bank, channel and berm

Potential construction noise impacts on nearby residences

Potential for a reduction in air quality caused by the generation of dust during construction

Other changes in amenity and environmental risks including visual impacts and waste.

Due to the small scale of the proposal and the proposed design measures and safeguards, the proposal would be unlikely to cause significant environmental impacts during construction.

Where possible, impacts would be avoided or minimised through the implementation of site-specific safeguards. The proposal is unlikely to have a significant long-term impact on the environment or the community. On balance, it is considered that the adverse environmental impacts of the proposal are outweighed by the benefit of the proposal and that the proposal is therefore justified.

8.2 Objects of the EP&A Act

The objects of the EP&A Act are listed in Table 8.1.


Table 8.1: Objects of the EP&A Act

Object Comment

5(a)(i) To encourage the proper management, development and conservation of natural and artificial resources, including agricultural land, natural areas, forests, minerals, water, cities, towns and villages for the purpose of promoting the social and economic welfare of the community and a better environment.

The proposal would remove about 500 square metres of grassland that forms the threatened ecological community Weeping Myall Woodland and about 17 native trees. The proposal could potentially cause the further spread of weeds in the study area.

The proposal has the potential to cause impacts to residences in the study area during construction through noise and generation of dust.

5(a)(ii) To encourage the promotion and co-ordination of the orderly economic use and development of land.

Council is undertaking consultation and environmental assessments required to properly plan and develop the proposal without undue impacts to the local economy.

The increased flood protection achieved by the proposal would benefit the economy by reducing the potential damages and economic impacts caused by floods.

5(a)(iii) To encourage the protection, provision and co-ordination of communication and utility services.

Water and communications utility services exist in the vicinity of the proposal, as detailed in section 3.5. Council would consult with the relevant service providers to address issues relating to potential public utility adjustment.

5(a)(iv) To encourage the provision of land for public purposes.

The proposal would temporarily affect access to the Town Common and TSR during the construction period. Although access would still be available to the general area, the construction site would be closed to public access for the construction period.

5(a)(v) To encourage the provision and co-ordination of community services and facilities.

The proposal is unlikely to substantially affect the use of community facilities by the public.

5(a)(vi) To encourage the protection of the environment, including the protection and conservation of native animals and plants, including threatened species, populations and ecological communities, and their habitats.

The proposal would remove about 500 square metres of grassland that forms the threatened ecological community Weeping Myall Woodland and about 17 native trees (not part of the threatened community). The proposal could potentially cause the spread of weeds in the study area. The proposal would be unlikely to have a significant impact on any listed species, population or ecological community.

5(a)(vii) To encourage ecologically sustainable development.

Ecologically sustainable development is considered in Sections 8.2.1 – 8.2.4 below.

5(a)(viii) To encourage the provision and maintenance of affordable housing.

Not relevant to the project.

5(b) To promote the sharing of the responsibility for environmental planning between different levels of government in the State.

including the Aboriginal community. Issues raised during consultation in relation to the proposal have been addressed during the environmental planning and assessment process.

8.2.1 The precautionary principle

This principle states that “if there are threats of serious or irreversible damage, lack of scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation”.

The environmental consequences of the proposal have been assessed as accurately as possible using appropriate specialists in relevant disciplines where required. The assessment process involved computer flood modelling, analysis and interpretation of the potential environmental impacts associated with the proposal. This process has enabled the impacts of the proposal to be predicted within a reasonable degree of certainty. All predictions, however, contain a degree of variability, which reflects the variable nature of the environment.

The proposed works are not anticipated to result in serious or irreversible damage. Under the proposal, as a requirement of the CEMP, environmental monitoring will be undertaken as a precautionary measure to reduce any uncertainty regarding the potential for environmental damage. No mitigation measures or management mechanisms would be postponed as a result of a lack of information.

8.2.2 Intergenerational equity

The principle states that ”the present generation should ensure that the health, diversity and productivity of the environment is maintained or enhanced for the benefit of future generations”.

The proposal would have a major long-term benefit for future generations by providing increased flood protection for residents of Lockhart. This would reduce the likelihood of flood damages and the associated economic costs and disruption to the community.

The proposal would benefit future generations by ensuring that proposed works do not give rise to significant long-term adverse impacts. Potential impacts would be minimised by the implementation of appropriate safeguards.

Should the proposal not proceed, the principle of intergenerational equity may be compromised, as future generations would inherit a sub-standard level of flood protection. The community would be at risk of suffering damages from floods that could otherwise be protected against.

8.2.3 Conservation of biological diversity and ecological integrity

This principle states that the “diversity of genes, species, populations and communities, as well as the ecosystems and habitats to which they belong, must be maintained and improved to ensure their survival”.

An assessment of the existing local environment has been undertaken in order to identify and manage any potential impacts of the proposal on local biodiversity. The proposal would involve the removal of about 500 square metres of Weeping Myall Woodland, which provides habitat for native fauna and flora species. The proposal is considered unlikely to significantly impact on any species, population or ecological community listed under the TSC Act or EPBC Act.

An ecological assessment and appropriate site-specific safeguards are provided in section 6.1.4 of this REF. Safeguards include consideration of design impacts upon biodiversity, vegetation management and weed management.


8.2.4 Improved valuation, pricing and incentive mechanisms

This principle requires that “costs to the environment should be factored into the economic costs of a project”.

The REF has examined the environmental consequences of the proposal and identified mitigation measures for areas which have the potential to experience adverse impacts. Requirements imposed in terms of implementation of these mitigation measures would result in an economic cost to Council. The implementation of mitigation measures would increase both the capital and operating costs of the proposal. This signifies that environmental resources have been given appropriate valuation.

The design for the proposal has been developed with an objective of minimising potential impacts on the surrounding environment. This indicates that the concept design for the proposal has been developed with an objective to minimise environmental impacts.

8.3 Conclusion

Council proposes to construct a levee bank at Government Dam as part of the flood mitigation works investigated for Lockhart. The proposal also includes constructing a channel and berm east of Lockhart – Collingullie Road.

The proposal is required to increase the level of flood protection for residents south of Brookong Creek and would achieve a levee crest with 500 millimetres of freeboard above the 100 year ARI flood level.

The proposal is subject to assessment under Part 5 of the EP&A Act. The REF has examined and taken into account to the fullest extent possible all matters affecting or likely to affect the environment by reason of the proposed activity.

The proposal as described in this review of environmental factors best meets the project objectives but would still result in impacts relating to biodiversity, soils, land use, noise and air quality.

Adverse environmental effects would be minimised through the implementation of safeguards and mitigation measures outlined in this review of environmental factors.

The proposal would have beneficial impacts by providing increased flood protection for residents of Lockhart. This would reduce the likelihood of flood damages to residents and the associated economic costs and disruption to the community.

On balance, it is considered that the adverse environmental impacts of the proposal are outweighed by the beneficial effects and that the proposal is therefore justified.

This review of environmental factors concludes that the proposal is unlikely to have a significant impact on any species, population or ecological community listed under the Threatened Species Conservation Act 1995. A species impact statement is not therefore required.

This review of environmental factors finds that the proposal is unlikely to have a significant environmental impact and therefore an Environmental Impact Statement is not required. Approval from the Minister for Planning and Infrastructure under Part 5.1 of the Environmental Planning and Assessment Act 1979 would not be required.

This review of environmental factors finds that the proposal is unlikely to have a significant impact on any matter of national environmental significance listed under the Environment Protection and Biodiversity Conservation Act 1999. A referral to the Commonwealth Department of Sustainability, Environment, Water, Population and Communities is not therefore required.

Appendices


Appendix A – Consideration of clause 228 (2) factors and matters of natural environmental significance

Clause 228(2) factors In addition to the requirements of the guideline ‘Is an EIS required?’ as detailed in the REF, the following factors, listed in clause 228(2) of the Environmental Planning and Assessment Regulation 2000, have also been considered to assess the likely impacts of the proposal on the natural and built environment.

Factor Impact

a. Any environmental impact on a community?

Residences in the study area would potentially be affected during construction by noise from construction plant, machinery and vehicles as well as air quality impacts through generation of dust. Visual impacts would occur from earthworks, the compound and stockpile site and machinery. These impacts would be short-term and would be minimised through the implementation of safeguards detailed in sections 6.5.5, 6.6.3 and 6.7.3.

Short-term minor negative

The proposal would not affect the use of the Crown Land and rural land by the property owner in the long term, although there would be minor temporary restrictions to use of the land during construction.

Short and long-term minor negative

The construction of the proposal would have low long-term visual impacts through the excavation of the site and construction of the levee and berm. These impacts would be minimised by the low grade of the batters and rehabilitating the proposal site following construction.

Long-term minor negative

The proposal would increase the level of flood protection for residents in Lockhart, reducing the potential for flood damages and the associated economic costs and disruption to the community.

Long-term positive

b. Any transformation of a locality?

The construction of the proposal would have low long-term visual impacts through the excavation of the site and construction of the levee and berm. These impacts would be minimised by the low grade of the batters and rehabilitating the proposal site following construction.


c. Any environmental impact on the ecosystems of the locality?

The proposal would remove about 500 square metres of grassland that forms the threatened ecological community Weeping Myall Woodland and about 17 trees. The proposal could potentially cause the further spread of weeds in the study area. Safeguards to minimise impacts would be implemented as described in section 6.1.4. The proposal would be unlikely to have a significant impact.


d. Any reduction of the aesthetic, recreational, scientific or other environmental quality or value of a locality?

Residences in the study area would potentially be affected during construction by construction impacts as detailed in (a) above.


e. Any effect on a locality, place or building having aesthetic, anthropological, archaeological, architectural, cultural, historical, scientific or social significance or other special value for present or future generations?


The proposal has the potential to impact on sites of Aboriginal heritage value that are present in the Government Dam site. Safeguards to avoid or minimise impacts on heritage would be implemented as detailed in sections 6.8.4 and 6.9.4.

Nil

f. Any impact on the habitat of protected fauna (within the meaning of the National Parks and Wildlife Act 1974)?

The proposal would remove 500 square metres of Weeping Myall Woodland and 17 trees, which provides habitat for native fauna protected under the NPW Act, including species listed as threatened under the TSC Act, as described in (g) below. The ecological assessment found that the proposal would be unlikely to impact fauna species due to the limited vegetation removal required and the presence of additional habitat in the study area. Safeguards would be implemented as described in section 6.1.4.


g. Any endangering of any species of animal, plant or other form of life, whether living on land, in water or in the air?

The proposal would remove 500 square metres of Weeping Myall Woodland that forms a threatened ecological community in addition to 17 trees. The proposal could potentially cause the spread of weeds in the study area. The proposal would be unlikely to endanger any species of animal, plant or other form of life. Safeguards to minimise impacts would be implemented as described in section 6.1.4.


h. Any long-term effects on the environment?

The proposal could potentially cause minor long-term ecological impacts as described in (g) above.


The proposal would increase the level of flood protection for residents in Lockhart, as described in (a) above.

Long-term positive

i. Any degradation of the quality of the environment?

Residences in the study area could potentially be affected by construction impacts as described in (a) above.


The proposal would have a minor impact on the quality of the environment through the ecological impacts described in (g) above.


j. Any risk to the safety of the environment?

There is potential for safety to be reduced during the construction of the proposal. Traffic management safeguards described in section 6.10.3 would address safety risks in relation to work near roads. Standard safety measures would be implemented to restrict public access to the proposal site during construction.


k. Any reduction in the range of beneficial uses of the environment?

The proposal would acquire land from a private property zoned for rural uses; however it would not impact surrounding land uses in the long term. The construction of the proposal would not affect the long-term use of this land, although there would be minor temporary restrictions to the use of the land during construction.


l. Any pollution of the environment?

Galore Street residences could potentially be affected by construction impacts as described in (a) above.



During construction the proposal could potentially result in soil and water pollution, including pollution of the drainage lines in the study area. Pollution could result from sedimentation or chemical and fuel spills. Management of soil and water quality impacts would be undertaken in accordance with the safeguards outlined in section 6.2.3.


Waste generated during construction could also pollute the environment. Waste would be managed in accordance with the safeguards outlined in section 6.12.3.


m. Any environmental problems associated with the disposal of waste?

The proposal would be unlikely to generate contaminated waste during construction. Other waste streams generated during construction are common and would pose no difficulty in their disposal. Waste would be recycled wherever possible. Waste would be managed in accordance with the safeguards outlined in section 6.12.3.

Nil

n. Any increased demands on resources (natural or otherwise) that are, or are likely to become, in short supply?

All resources required for the proposal are readily available and are not in short supply.

Nil

o. Any cumulative environmental effect with other existing or likely future activities?

The cumulative effects of the proposal are discussed in section 6.15. Short-term cumulative impacts relate to soils and water quality, visual amenity and air quality impacts. The proposal would be likely to have relatively minor cumulative impacts in relation to these factors.


Long-term cumulative impacts relate to biodiversity and land use impacts. The proposal would be likely to have relatively minor cumulative impacts in relation to these factors.


p. Any impact on coastal processes and coastal hazards, including those under projected climate change conditions?

The proposal is not located within a coastal area, and would not cause any impact on coastal processes and coastal hazards.

Nil

Appendix C – Likelihood of occurrence An evaluation of the likelihood and extent of impact to threatened and migratory fauna recorded from within the Lockhart LGA (TSC Act threatened species); and within a 10 kilometre radius of the proposal site (EPBC Act threatened and migratory species). Records are from a search of the Office of Environment and Heritage (OEH) Wildlife Atlas, and the EPBC Environmental Reporting Tool available from the Department of the Environment and Energy (DotEE) website. Ecology information has been obtained from the Threatened Species Profiles on the NSW OEH website (http://www.environment.nsw.gov.au/threatenedspecies/) and from the Species Profiles and Threats Database on the Commonwealth DotE website (http://www.environment.gov.au/cgi-bin/sprat/public/sprat.pl).

Likelihood of occurrence in study area

Recorded – The species was observed in the study area during the current survey

High – It is highly likely that a species inhabits the study area and is dependent on identified suitable habitat (i.e. for breeding or important life cycle periods such as winter flowering resources), has been recorded recently in the locality (within 10 kilometres) and is known or likely to maintain resident populations in the study area. Also includes species known or likely to visit the study area during regular seasonal movements or migration

Moderate – Potential habitat is present in the study area. Species unlikely to maintain sedentary populations, however may seasonally use resources within the study area opportunistically or during migration. The species is unlikely to be dependent (ie. for breeding or important life cycle periods such as winter flowering resources) on habitat within the study area, or habitat is in a modified or degraded state. Includes cryptic flowering flora species that were not seasonally targeted by surveys and that have not been recorded

Low – It is unlikely that the species inhabits the study area and has not been recorded recently in the locality (within 10 kilometres). It may be an occasional visitor, but habitat similar to the study area is widely distributed in the local area, meaning that the species is not dependent (i.e. for breeding or important life cycle periods such as winter flowering resources) on available habitat. Specific habitat is not present in the study area or the species are a non-cryptic perennial flora species that were specifically targeted by surveys and not recorded

None – Suitable habitat is absent from the study area.

Grey Box grassy woodlands and derived native grasslands of south-eastern Australia

E E Predominantly occurs on the drier edge of the temperate grassy eucalypt woodland belt (375-700 mm rainfall) ranging from central New South Wales through northern and central Victoria into South Australia. Grey Box Grassy Woodlands usually occur in flat to undulating landscapes, such as plains, low slopes and rises, or occasionally in drainage depressions. Patches of this community tend to occur on relatively productive soils.

Recorded – the study area contains small patches of Grey Box Woodland. Grey Box trees to be removed are paddock trees. Only NSW form of community occurs as canopy trees.

Natural grasslands of the Murray Valley Plains

CE - It typically occurs on a landscape of flat alluvial lowland plains with heavy-textured grey, brown and red clays. Distribution is primarily in the southern parts of the Riverina bioregion, with occurrences also on the Wimmera plains of the Murray Darling Depression bioregion. Other outlying occurrences are also in the Murray Darling Depression bioregion and the NSW South.

None – the understorey is dominated by introduced species with scattered paddock trees. The community does not occur.

Seasonal herbaceous wetlands (freshwater) of the temperate lowland plains

CE - Mainly occur on the lowland plains of Victoria, south-eastern South Australia (SA), and southern New South Wales (NSW). In some places the plains may be broken by local areas of higher relief, (e.g. stony rises on the Victorian Volcanic Plain), or grade into hills, (e.g. where plains grade into the Victorian Midlands bioregion).

None – No natural wetlands occur. Wet areas are farm dams.

Weeping Myall woodlands

E E The Weeping Myall Woodlands occurs on the inland alluvial plains west of the Great Dividing Range in NSW and QLD. It occurs in the Riverina, NSW South Western Slopes, Darling Riverine Plains, Brigalow Belt South, Murray-Darling Depression, Nandewar and Cobar Peneplain Interim Biogeographic Regionalisation for Australia (IBRA) bioregions.

Recorded – The community is present in the TSR in the study area and due to the removal of grassland that forms the community the proposal would impact on the community.

Flora

A spear-grass Austrostipa wakoolica

E E Grows on floodplains of the Murray River tributaries, in open woodland on grey, silty clay or sandy loam soils; habitats include the edges of a lignum swamp with box and mallee; creek banks in grey, silty clay; mallee and lignum sandy-loam flat; open Cypress Pine forest on low sandy range; and a low, rocky rise. Associated species include Callitris glaucophylla, Eucalyptus microcarpa, E. populnea, Austrostipa eremophila, A. drummondii, Austrodanthonia eriantha and Einadia nutans. Known from the locality.

Low – Suitable habitat may be available for this species in the wider locality but no suitable potential habitat would be impacted by the proposal.

Claypan Daisy Brachyscome muelleroides

V V Occurs in seasonally damp situations such as shallow depressions and around the margins of swamps, lagoons and clay pans, on heavy grey cracking clays to lighter clay loam soils, in grassland, grassy woodland and open forest habitats, growing in association with various grasses and seasonal aquatic plants such as Marsilea species. Known from the locality, most recent record 1951.

Low – Suitable habitat may be available for this species in the wider locality but no suitable potential habitat would be impacted by the proposal.

Small Scurf-Pea Cullen parvum

- E The species grows in grasslands and grassy woodlands. These sites are subject to irregular flooding, and have relatively rich soils derived from alluvium. An exception is the population near Shelford, which grows on rocky clay soils derived from basalt. Known from the locality, most recent record 2007.

Low – Suitable habitat exists within the study area for this species. However due to the highly disturbed nature of habitat to be impacted, an impact on potential habitat is not likely.

Pine Donkey Orchid Diuris tricolour

Black Falcon Falco subniger

- V The Black Falcon is widely, but sparsely, distributed in New South Wales, mostly occurring in inland regions. In New South Wales there is assumed to be a single population that is continuous with a broader continental population, given that falcons are highly mobile, commonly travelling hundreds of kilometres. The Black Falcon occurs as solitary individuals, in pairs, or in family groups of parents and offspring.

Most recent records from 1994.

Low – Species may forage or hunt within the wider study area but potential habitat would not be impacted by the proposal.

Brolga Grus rubicunda

- V Brolgas forage in dry grassland or ploughed paddocks or even desert clay pans, they are dependent on wetlands too, especially shallow swamps, where they will forage with their head entirely submerged.

Low – area to be impacted does not contain suitable potential habitat and is not wetland habitat.

It is still abundant in the northern tropics, but very sparse across the southern part of its range. Most recent records from 2004.

Brown Treecreeper (eastern subspecies) Climacteris picumnus victoriae

- V Found in eucalypt woodlands (including Box-Gum Woodland) and dry open forest of the inland slopes and plains inland of the Great Dividing Range. The species mainly inhabits woodlands dominated by stringybarks or other rough-barked eucalypts, usually with an open grassy understorey, sometimes with one or more shrub species, and is also found in mallee and River Red Gum Forest bordering wetlands with an open understorey of acacias, saltbush, lignum, cumbungi and grasses. They are usually not found in woodlands with a dense shrub layer. Most recent records from 2004.

Low – lack of woodland vegetation the study area and subject site. Removal of paddock trees unlikely to be suitable habitat for species.

Bush Stone Curlew Burhinus grallarius

E E The curlew likes to roost and nest in grassy woodlands of Buloke, gum or box with low, sparse grassy or herb understorey. Nests are usually beside a fallen log, which probably makes it harder for foxes to find. Curlews prefer a sparse understorey so they can see predators while foraging for insects.

Low – Suitable habitat for this species is not available within the study area or area to be impacted.

Dusky Woodswallow Artamus cyanopterus

- V The Dusky Woodswallow is often reported in woodlands and dry open sclerophyll forests, usually dominated by eucalypts, including mallee associations. It has also been recorded in shrublands and heathlands and various modified habitats. The ground cover may consist of grasses, sedges or open ground, often with coarse woody debris. Birds are also often observed in farm land, usually at the edges of forest or woodland or in roadside remnants or wind breaks with dead timber. Most recent records from 1994.

Low - lack of woodland vegetation the study area and proposal site. Removal of paddock trees unlikely to be suitable habitat for species.

Diamond Firetail Stagonopleura guttata

- V Diamond Firetails prefer rough grassy woodland as a habitat, and can be found on the outskirts of the suburbs. They are much less sociable than other native finches but sometimes group together in small flocks. They do not appear to be able to cope with the suburban habitat. Diamond Firetails are found in open grassy woodland, heath

Flame Robin Petroica phoenicea

- V The Flame Robin prefers forest and woodland habitats up to about 1800 m above sea level. In winter, birds move to lower and more open areas, including gardens. In NSW it breeds in upland moist eucalypt forests and woodlands, often on ridges and slopes, in areas of open understorey. It migrates in winter to more open lowland habitats such as grassland with scattered trees and open woodland on the inland slopes and plains.


Low - lack of woodland vegetation the study area and proposal site. Removal of paddock trees unlikely to be suitable habitat for species.

Fork-tailed Swift Apus pacificus

Mi - Migratory marine visitor to eastern Australia. The Fork-tailed Swift is almost exclusively aerial, flying from less than 1 m to at least 300 m above ground and probably much higher. It is a highly nomadic and dispersive species which feeds on insects in the air. The species occurs over inland plains, and settled areas, including towns, urban areas and cities. The species mostly occurs over dry or open habitats, including riparian woodland and tea-tree swamps, low scrub, heathland or saltmarsh. The species is also found in treeless grassland and sandplains covered with spinifex, open farmland and inland and coastal sand-dunes. Known from the wider subregion.

Low - lack of woodland vegetation the study area and proposal site. Removal of paddock trees unlikely to be suitable habitat for species and the species is mostly aerial.

Glossy Black Cockatoo Calyptorhynchus lathami

- V The glossy black-cockatoo lives in coastal woodlands and drier forest areas, open inland woodlands or timbered watercourses where casuarinas (or sheoaks), its main food trees, are common. Scientists think that glossy black-cockatoos prefer to live in rugged country, where extensive clearing has not taken place. Brigalow scrub or hilly rocky country containing casuarina species tend to be their preferred habitat in inland NSW. Most recent records from 2008.

Low – The study area has been extensively cleared and doesn’t contain Casuarina feed tree species the cockatoo feeds on.

Grey-crowned Babbler (eastern subspecies) Pomatostomus temporalis temporalis

- V Inhabits open Box-Gum Woodlands on the slopes, and Box-Cypress-pine and open Box Woodlands on alluvial plains. Flight is laborious so birds prefer to hop to the top of a tree and glide down to the next one. Birds are generally unable to cross large open areas.

The species was recorded in the study area during surveys.

Recorded – The species was recorded in the study area during surveys.

Hooded Robin (south-eastern form) Melanodryas cucullata cucullata

- V Prefers lightly wooded country, usually open eucalypt woodland, acacia scrub and mallee, often in or near clearings or open areas. Requires structurally diverse habitats featuring mature eucalypts, saplings, some small shrubs and a ground layer of moderately tall native grasses. Most recent records from 2004.

Low - Suitable potential habitat that is structurally diverse does not occur in the area to be impacted by the proposal.

Little Eagle Hieraaetus morphnoides

- V Occupies open eucalypt forest, woodland or open woodland. Sheoak or Acacia woodlands and riparian woodlands of interior NSW are also used. Nests in tall living trees within a remnant patch, where pairs build a large stick nest in winter.

Previously recorded in 1994.

Low - Species may enter the study area in search of food, however the species is unlikely to rely on the trees to be removed as habitat.

Painted Honeyeater Grantiella picta

V V Inhabits Boree/ Weeping Myall (Acacia pendula), Brigalow (A. harpophylla) and Box-Gum Woodlands and Box-Ironbark Forests. The Painted Honeyeater is nomadic and occurs at low densities throughout its range. During the winter it is more likely to be found in the north of its distribution. Known from the wider subregion.

Low - this species is dependent upon mistletoes for foraging of which none were observed in the area to be impacted. Potential habitat unlikely to be impacted.

Satin Flycatcher Myiagra cyanoleuca

Spotted Harrier Circus assimilis

- V The Spotted Harrier is found in open wooded country in tropical and temperate Australia, particularly in arid and semi-arid areas. Also occurs in grassy open woodland including Acacia and mallee remnants, inland riparian woodland, grassland and shrub steppe. It is found most commonly in native grassland, but also occurs in agricultural land, foraging over open habitats including edges of inland wetlands.


Low - The proposal site contains open woodland near ephemeral waterways that the species may use for foraging but the removal of paddock trees is unlikely to impact the species.

Superb Parrot Polytelis swainsonii

V V The species inhabits Box-Gum, Box-Cypress-pine and Boree Woodlands and River Red Gum Forest. In the Riverina the birds nest in the hollows of large trees (dead or alive) mainly in tall riparian River Red Gum Forest or Woodland. On the South West Slopes nest trees can be in open Box-Gum Woodland or isolated paddock trees. Species known to be used are Blakely’s Red Gum, Yellow Box, Apple Box and Red Box. May forage up to 10 km from nesting sites, primarily in grassy box woodland.

Known from the wider subregion.

Low – Suitable habitat exists within the study area; however the species is unlikely to be impacted due to the minimal vegetation removal required.

Varied Sittella Daphoenositta chrysoptera

- V Inhabits eucalypt forests and woodlands, especially those containing rough-barked species and mature smooth-barked gums with dead branches, mallee and Acacia woodland. The Varied Sittella is sedentary and inhabits most of mainland Australia except the treeless deserts and open grasslands. Distribution in NSW is nearly continuous from the coast to the far west.

Previously recorded in 1994.

Low - The proposal site does not contain suitable woodland habitat for this species and the six trees to be removed are unlikely to be habitat for this species.

Mammals

Squirrel Glider Petaurus norfolcensis

- V Inhabits mature or old growth Box, Box-Ironbark woodlands and River Red Gum forest west of the Great Dividing Range and Blackbutt-Bloodwood forest with heath understorey in coastal areas. Prefers mixed species stands with a shrub or Acacia midstorey. Require abundant tree hollows for refuge and nest sites. Previously recorded in 1920.

Low – the vegetation in the study area has been largely cleared. The isolated trees to be removed are unlikely to support this species due to a lack of connectivity.

Grey-headed Flying Fox

V V The Grey-headed Flying-fox requires foraging resources and roosting sites. It is a canopy-feeding frugivore and nectarivore, which utilises vegetation communities including rainforests, open forests, closed and open woodlands, Melaleuca swamps and Banksia woodlands. It also feeds on commercial fruit crops and on introduced tree species in urban areas. The primary food source is blossom from Eucalyptus and related genera but in some areas it also utilises a wide range of rainforest fruits. None of the vegetation communities used by the Grey-headed Flying-fox produce continuous foraging resources throughout the year. As a result, the species has adopted complex migration traits in response to ephemeral and patchy food resources. Known from the wider locality.

Low – Suitable foraging habitat is not found within the study area. Species may be a seasonal vagrant.

Bats

Corben’s Long-eared Bat Nyctophilus corbeni

Appendix D – Assessments of significance

EP&A Act Assessments of Significance Section 5A of the EP&A Act lists seven factors that must be taken into account in the determination of the significance of potential impacts of an activity on ‘threatened species, populations or ecological communities (or their habitats)’ listed under the TSC Act. The ‘7 part test’ is used to determine whether an activity is ‘likely’ to impose ‘a significant effect’ on threatened biota and thus whether a species impact statement (SIS) is required. Should the 7 part test conclude that a significant effect is likely, an SIS must be prepared.


Weeping Myall Woodland

a) in the case of a threatened species, whether the action proposed is likely to have an adverse effect on the life cycle of the species such that a viable local population of the species is likely to be placed at risk of extinction,

A threatened species is not the subject of this assessment of significance.

b) in the case of an endangered population, whether the action proposed is likely to have an adverse effect on the life cycle of the species that constitutes the endangered population such that a viable local population of the species is likely to be placed at risk of extinction

An endangered population is not the subject of this assessment of significance.

c) in the case of an endangered ecological community or critically endangered ecological community, whether the action proposed:

i) is likely to have an adverse effect on the extent of the ecological community such that its local occurrence is likely to be placed at risk of extinction, or

The proposal would remove about 500 square metres of grassland from within the Weeping Myall Woodland community. The vegetation removal would be comprised of groundcover dominated by native species, with no trees to be removed. The vegetation to be removed is located within an area disturbed by grazing and agricultural activities due to its use as a TSR, and therefore the groundcover in the area, while dominated by native species, contains a low diversity.

The proposal would affect only a minor fraction of the woodland in the study area, which is located along road reserves in the locality, including the Lockhart – Collingullie Road, and within the TSR. The vegetation removal would not result in the complete removal of any stand of Weeping Myall Woodland from within the study area. Large areas of the community would not be cleared, with removal to be limited to groundcover vegetation.

The removal of a relatively small area of the community would be unlikely to have an adverse effect on the extent of the Weeping Myall Woodland ecological community such that its local occurrence would be likely to be placed at risk of extinction.

ii) is likely to substantially and adversely modify the composition of the ecological community such that its local occurrence is likely to be placed at risk of extinction

The groundcover vegetation of most of the proposal site has previously been disturbed due to agricultural land use activities in the TSR, and while dominated by native species, contains a

low diversity. The proposal has the potential to modify the composition and further degrade the ecological community by creating conditions conducive to the spread of weed species. This could occur through general disturbance from machinery and vehicles, and foot traffic. These conditions could lead to the introduction and spread of invasive species.

The proposal could also lead to an increase in the spread of weeds in Weeping Myall Woodland through edge effects associated with disturbance. This is of particular concern due to the Commonwealth listing of the ecological community, which requires a native dominated understorey to maintain their listing. The existing presence of weeds in the study area is likely to have occurred through disturbance created by the construction of linear infrastructure and agricultural land uses in the study area. It is likely therefore that further development would increase the potential for weeds to further invade areas of the community. This could lead to a further decline in the quality of Weeping Myall Woodland in the study area.

The proposal also has the potential to result in pathogen spread, particularly during construction. Pathogens have the potential to modify the composition of the community, however, no pathogens were observed during the surveys. Safeguards detailed in section 6.1 would be put in place to stop pathogen introduction and reduce the spread of weeds. Due to the small area likely to be impacted by the proposal, and the retention of all trees within the community, the proposal would be unlikely to substantially and adversely modify the composition of the ecological communities.

d) in relation to the habitat of a threatened species, population or ecological community:

i) the extent to which habitat is likely to be removed or modified as a result of the action proposed, and

The proposal would remove about 500 square metres of grassland from within the Weeping Myall Woodland community. The vegetation removal would be comprised of groundcover dominated by native species, with no trees to be removed. The proposal would not remove woody debris.

The proposed vegetation removal is likely to represent a small fraction of the community in the study area, which is located along road reserves in the locality, including the Lockhart – Collingullie Road, and within the TSR.

ii) whether an area of habitat is likely to become fragmented or isolated from other areas of habitat as a result of the proposed action, and

Fragmentation of the vegetation in the locality has previously occurred through the development of surrounding areas for agriculture, residential properties and for the construction of linear infrastructure (such as transmission lines and roads). These developments have created barriers to movement for some fauna species, particularly those that are limited by dispersal abilities and habitat preferences.

The proposal is unlikely to further fragment woodland habitat throughout the study area as the majority of vegetation removal is comprised of groundcover vegetation that would be allowed to regenerate following completion of the proposal, and only scattered trees not from the Weeping Myall community would require removal.

The proposal is unlikely to increase the distance between mature trees and would not create additional gaps in the canopy, as trees to be removed are largely comprised of scattered trees and plantings with only one tree over 40 centimetres in diameter at breast height to be removed. The trees to be removed do not form part of the Weeping Myall community. The proposal would

not remove any large areas of native vegetation, sever any important corridors or otherwise isolate any areas of habitat. Woody debris would be maintained.

iii) the importance of the habitat to be removed, modified, fragmented or isolated to the long-term survival of the species, population or ecological community in the locality


The proposal would not result in the clearing of large patches or create new barriers through previously undisturbed patches. Vegetation to be removed represents a small fraction of the habitat likely to be available for the community in the locality. The habitat to be removed would therefore not put the long-term survival of the ecological communities in the locality at risk.

e) whether the action proposed is likely to have an adverse effect on critical habitat (either directly or indirectly)

The proposal would not affect any habitat listed on the critical habitat register.

f) whether the action proposed is consistent with the objectives or actions of a recovery plan or threat abatement plan

There is no state recovery plan for Weeping Myall Woodland. However, the OEH (2017) Threatened Species website identifies a number of actions that need to occur to recover the community that are relevant to the proposal:

Conduct integrated weed control

Ensure no further loss of Myall Woodland.

The proposal is not consistent with the recovery actions for the community, as it involves the clearing and/or modification of areas of the community. However, specific avoidance measures have been taken to avoid impacts as far as possible. The impacts are likely to be minor and are unlikely to interfere with the recovery of any of the community. The proposal will not increase fragmentation to any significant extent. Specific mitigation measures are proposed to manage key threats such as weeds.

g) whether the action proposed constitutes or is part of a key threatening process or is likely to result in the operation of, or increase the impact of, a key threatening process

The proposed action constitutes one listed key threatening processes relevant to the Weeping Myall Woodland ecological community:

Clearing of native vegetation – The proposal would remove about 500 square metres of groundcover from within the Weeping Myall Woodland community. This is unlikely to represent a significant loss of the ecological community, for the reasons detailed above.

Conclusion

The proposal would be unlikely to cause a significant ecological impact on the Weeping Myall Woodland ecological community because:

Clearing would be limited to groundcover vegetation within a previously disturbed area, with trees to be retained

The area of vegetation to be removed is minimal compared to the area of habitat available within the study area and locality.

EPBC Act Assessments of Significance

1) Are there any matters of national environmental significance located in the area of the proposed action?

The following MNES are known or likely to occur in the area of the proposed action:

Weeping Myall Woodlands (Endangered)

2) Considering the proposed action at its broadest scope, is there potential for impacts on matters of national environmental significance?

The proposal would remove about 500 square metres of grassland from within the Weeping Myall Woodland community. The vegetation removal would be comprised of groundcover dominated by native species, with no trees to be removed. The vegetation to be removed is located within an area disturbed by grazing and agricultural activities due to its use as a TSR, and therefore the groundcover in the area, while dominated by native species, contains a low diversity. This would not result in the complete removal of vegetation and habitat resources within the proposal site, or any complete patch of Weeping Myall Woodland. Large areas of the community would not be cleared, with removal to be limited to groundcover vegetation.

Due to the minor nature of impacts and the small area of native vegetation to be removed, the proposal is unlikely to impact on any other matters of national environmental significance.

Are any impacts of the proposed action on matters of national environmental significance likely to be significant impacts?

Safeguards and mitigation measures have been prepared with the aim of minimising impacts of the proposal on the ecology of the study area and on Matters of NES. These are detailed in section 6.1 of this report.

Endangered ecological community – Weeping Myall Woodland

An action is likely to have a significant impact on a critically endangered or endangered ecological community if there is a real chance or possibility that it will:

Reduce the extent of an ecological community;

The proposal would remove about 500 square metres of grassland from within the Weeping Myall Woodland community, as listed under the EPBC Act. The vegetation removal would be comprised of groundcover dominated by native species, with no trees to be removed. The vegetation to be removed is located within an area disturbed by grazing and agricultural activities due to its use as a TSR, and therefore the groundcover in the area, while dominated by native species, contains a low diversity.

The proposal would affect only a minor fraction of the woodland in the study area, which is located along road reserves in the locality, including the Lockhart – Collingullie Road, and within the TSR. The vegetation removal would not result in the complete removal of any stand of Weeping Myall Woodland from within the study area. Large areas of the community would not be cleared, with removal to be limited to groundcover vegetation.

The removal of a relatively small area of the community would be unlikely to have an adverse effect on the extent of the Weeping Myall Woodland ecological community.

Fragment or increase fragmentation of an ecological community, for example by clearing vegetation for roads or transmission lines; Fragmentation of the vegetation in the locality has previously occurred through the development of surrounding areas for agriculture, residential properties and for the construction of linear infrastructure (such as transmission lines and roads).

The proposal is unlikely to further fragment woodland habitat throughout the study area as the majority of vegetation removal is comprised of groundcover vegetation that would be allowed to regenerate following completion of the proposal, and only scattered trees that do not form part of the community would require removal. Woody debris would be maintained.

The proposal is unlikely to increase the distance between mature trees and would not create additional gaps in the canopy, as trees to be removed are largely comprised of scattered trees and plantings with only one tree over 40 centimetres in diameter at breast height to be removed (not from the community). The proposal would not remove any large areas of native vegetation, sever any important corridors or otherwise isolate any areas of habitat.

It is unlikely that the project would result in significant further fragmentation or isolation of this ecological community. Disturbance is likely to be minimised by the implementation of the safeguards and mitigation measures outlined in section 6.1.

Adversely affect habitat critical to the survival of an ecological community;


The proposal would not result in the clearing of large patches or create new barriers through previously undisturbed patches. Vegetation to be removed represents a small fraction of the habitat likely to be available for the community in the locality. The habitat to be removed would therefore not put the long-term survival of the ecological communities in the locality at risk.

Modify or destroy abiotic (non-living) factors (such as water, nutrients, or soil) necessary for an ecological community’s survival, including reduction of groundwater levels, or substantial alteration of surface water drainage patterns;

The vegetation in the study area is likely to be important in intercepting water infiltrating to the water table in the wider study area. However, no major issues are evident in the study area with salinity risks or similar and therefore the proposal would be unlikely to affect groundwater. Surface water drainage patterns would be impacted by the proposal as the construction of the levee, channel and berm would be designed to prevent severity of flooding south of Brookong Creek. This is only likely to occur during high rainfall and flooding events. The majority of vegetation removal is in previously degraded areas. Works on slopes would be undertaken with precaution and safeguards in place to minimise the risk of damage and erosion.

The proposal would be unlikely to modify or destroy abiotic (non-living) factors necessary for the ecological community’s survival.

Cause a substantial change in the species composition of an occurrence of an ecological community, including causing a decline or loss of functionally important species, for example through regular burning or flora or fauna harvesting;

The groundcover vegetation of most of the proposal site has previously been disturbed due to agricultural land use activities in the TSR, and while dominated by native species, contains a low diversity. The proposal has the potential to modify the composition and further degrade the ecological community by creating conditions conducive to the spread of weed species. This could occur through general disturbance from machinery and vehicles, and foot traffic. These conditions could lead to the introduction and spread of invasive species.

The proposal could also lead to an increase in the spread of weeds in Weeping Myall Woodland through edge effects associated with disturbance. This is of particular concern due to the Commonwealth listing of the ecological community, which requires a native dominated understorey to maintain its listing. The existing presence of weeds in the study area is likely to have occurred through disturbance created by the construction of linear infrastructure and agricultural land uses in the study area. It is likely therefore that further development would increase the potential for weeds to further invade areas of the community. This could lead to a further decline in the quality of Weeping Myall Woodland in the study area.

The proposal also has the potential to result in pathogen spread, particularly during construction. Pathogens have the potential to modify the composition of the community, however, no pathogens were observed during the surveys. Safeguards detailed in section 6.1 would be put in place to stop pathogen introduction and reduce the spread of weeds. Due to the small area likely to be impacted by the proposal, and the retention of all trees within the community, the proposal would be unlikely to substantially and adversely modify the composition of the ecological communities.

Cause a substantial reduction in the quality or integrity of an occurrence of an ecological community, including, but not limited to:

Assisting invasive species, that are harmful to the listed ecological community, to become established; or:

The proposal has the potential to further facilitate the introduction and spread of weed species. This could occur through general disturbance from machinery, vehicles, and foot traffic. These conditions could lead to the spread of invasive species such as White Horehound and Lippia.

The proposal could also lead to an increase in the spread of weeds in Weeping Myall Woodland through edge effects associated with disturbance, which is of particular concern in the Commonwealth areas of Weeping Myall Woodland that require a dominant native understorey to maintain their listing. The existing presence of weeds in the study area is likely to have occurred through disturbance created by the development of linear infrastructure and agricultural land uses in the study area. It is likely therefore that further development would increase the potential for weeds to further invade the remaining areas of Weeping Myall Woodland. This could lead to a decline in the quality of Weeping Myall Woodland in the study area. However, mitigation measures would be put in place to reduce spread of weeds that increase the degree of weed infestation of the ecological community such that the proposal would be unlikely to substantially and adversely modify the composition of the ecological community.

Causing regular mobilisation of fertilisers, herbicides or other chemicals or pollutants into the ecological community which kill or inhibit the growth of species in the ecological community; or

The proposal may require the use of herbicides; however, the following safeguard would be implemented:

A construction environmental management plan (CEMP) would be developed before the commencement of the works.

This would include a weed management plant and requirement for personnel and vehicles to be managed in a way that reduces the potential for the spread of weeds. The proposal also has the potential to result in chemical and fuel spills; however, with the implementation of safeguards, the proposal would be unlikely to kill or inhibit the growth of species in the ecological community, other than where appropriate.

Interfere with the recovery of an ecological community.

There is no national recovery plan for Weeping Myall Woodland. However, the OEH (2017) Threatened Species website identifies a number of actions that need to occur to recover the community that are relevant to the proposal:

Conduct integrated weed control

Ensure no further loss of Myall Woodland.

The proposal is not consistent with the recovery actions for the community, as it involves the clearing and/or modification of areas of the community. However, specific avoidance measures have been taken to avoid impacts as far as possible. The impacts are likely to be minor and are unlikely to interfere with the recovery of any of the community. The proposal will not increase fragmentation to any significant extent. Specific mitigation measures are proposed to manage key threats such as weeds

Conclusion

A significant impact on Weeping Myall Woodland is not likely because:

Clearing would be limited to groundcover vegetation within a previously disturbed area, with trees to be retained

The area of vegetation to be removed is minimal compared to the area of habitat available within the study area and locality.

The EPBC Act protects the environment on Commonwealth land, the environment from the actions taken onCommonwealth land, and the environment from actions taken by Commonwealth agencies. As heritage values of aplace are part of the 'environment', these aspects of the EPBC Act protect the Commonwealth Heritage values of aCommonwealth Heritage place. Information on the new heritage laws can be found athttp://www.environment.gov.au/heritage

This part of the report summarises other matters protected under the Act that may relate to the area you nominated.Approval may be required for a proposed activity that significantly affects the environment on Commonwealth land,when the action is outside the Commonwealth land, or the environment anywhere when the action is taken onCommonwealth land. Approval may also be required for the Commonwealth or Commonwealth agencies proposing totake an action that is likely to have a significant impact on the environment anywhere.

A permit may be required for activities in or on a Commonwealth area that may affect a member of a listed threatenedspecies or ecological community, a member of a listed migratory species, whales and other cetaceans, or a member ofa listed marine species.

- non-threatened seabirds which have only been mapped for recorded breeding sites

- migratory species that are very widespread, vagrant, or only occur in small numbers

- some species and ecological communities that have only recently been listed

Not all species listed under the EPBC Act have been mapped (see below) and therefore a report is a general guide only. Where available datasupports mapping, the type of presence that can be determined from the data is indicated in general terms. People using this information in makinga referral may need to consider the qualifications below and may need to seek and consider other information sources.

For threatened ecological communities where the distribution is well known, maps are derived from recovery plans, State vegetation maps, remotesensing imagery and other sources. Where threatened ecological community distributions are less well known, existing vegetation maps and pointlocation data are used to produce indicative distribution maps.

- seals which have only been mapped for breeding sites near the Australian continent

Such breeding sites may be important for the protection of the Commonwealth Marine environment.

Threatened, migratory and marine species distributions have been derived through a variety of methods. Where distributions are well known and iftime permits, maps are derived using either thematic spatial data (i.e. vegetation, soils, geology, elevation, aspect, terrain, etc) together with pointlocations and described habitat; or environmental modelling (MAXENT or BIOCLIM habitat modelling) using point locations and environmental datalayers.

The information presented in this report has been provided by a range of data sources as acknowledged at the end of the report.Caveat

This report is designed to assist in identifying the locations of places which may be relevant in determining obligations under the EnvironmentProtection and Biodiversity Conservation Act 1999. It holds mapped locations of World and National Heritage properties, Wetlands of Internationaland National Importance, Commonwealth and State/Territory reserves, listed threatened, migratory and marine species and listed threatenedecological communities. Mapping of Commonwealth land is not complete at this stage. Maps have been collated from a range of sources at variousresolutions.

- threatened species listed as extinct or considered as vagrants

- some terrestrial species that overfly the Commonwealth marine area

The following groups have been mapped, but may not cover the complete distribution of the species:

Only selected species covered by the following provisions of the EPBC Act have been mapped:

Where very little information is available for species or large number of maps are required in a short time-frame, maps are derived either from 0.04or 0.02 decimal degree cells; by an automated process using polygon capture techniques (static two kilometre grid cells, alpha-hull and convex hull);or captured manually or by using topographic features (national park boundaries, islands, etc). In the early stages of the distribution mappingprocess (1999-early 2000s) distributions were defined by degree blocks, 100K or 250K map sheets to rapidly create distribution maps. More reliabledistribution mapping methods are used to update these distributions as time permits.

If a site does not appear on the record it may still be affected by contamination. For example:

• Contamination may be present but the site has not been regulated by the EPA under the Contaminated Land Management Act 1997 or the Environmentally Hazardous Chemicals Act 1985.

• The EPA may be regulating contamination at the site through a licence or notice under the Protection of the Environment Operations Act 1997 (POEO Act).

• Contamination at the site may be being managed under the planning process.

More information about particular sites may be available from:

• The POEO public register• The appropriate planning authority: for example, on a planning certificate issued by the

local council under section 149 of the Environmental Planning and Assessment Act.

See What's in the record and What's not in the record.

If you want to know whether a specific site has been the subject of notices issued by the EPA under the CLM Act, we suggest that you search by Local Government Area only and carefully review the sites that are listed. This public record provides information about sites regulated by the EPA under the Contaminated Land Management Act 1997, including sites currently and previously regulated under the Environmentally Hazardous Chemicals Act 1985. Your inquiry using the above search criteria has not matched any record of current or former regulation. You should consider searching again using different criteria. The fact that a site does not appear on the record does not necessarily mean that it is not affected by contamination. The site may have been notified to the EPA but not yet assessed, or contamination may be present but the site is not yet being regulated by the EPA. Further information about particular sites may be available from the appropriate planning authority, for example, on a planning certificate issued by the local council under section 149 of the Environmental Planning and Assessment Act. In addition the EPA may be regulating contamination at the site through a licence under the Protection of the Environment Operations Act 1997. You may wish to search the POEO public register

Glossary

Term Description

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

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

dB Decibel is the unit used for expressing the sound pressure level (SPL) or power level (SWL) in acoustics.

dBA Decibel expressed with the frequency weighting filter used to measure ‘A-weighted’ sound pressure levels, which conforms approximately to the human ear response, as our hearing is less sensitive at low and high frequencies.

DECC Department of Environment and Climate Change

DECCW Department of Environment, Climate Change and Water

EPA Environment Protection Authority

Groundborne vibration

Groundborne vibration is vibration transmitted from source to receiver via the medium of the ground.

ICNG Interim Construction Noise Guideline (DECC, 2009).

INP Industrial Noise Policy (EPA, 2000).

LA90(period) The A-weighted sound pressure level that is exceeded for 90% of the time over which a given sound is measured. This is considered to represent the background noise e.g. LA90(15 min).

LAeq(period) Equivalent sound pressure level: the steady sound level that, over a specified period of time, would produce the same energy equivalence as the fluctuating sound level actually occurring.

LAmax(period) The maximum sound pressure level over a specified period of time.

Mitigation Reduction in severity.

Noise sensitive receiver

An area or place potentially affected by noise which includes: a residential dwelling. an educational institution, library, childcare centre or kindergarten. a hospital, surgery or other medical institution. an active (e.g. sports field, golf course) or passive (e.g. national park) recreational

area. commercial or industrial premises. a place of worship.

Rating Background Level

The overall single-figure background level representing each assessment period (day/evening/night) over the whole monitoring period. This is the level used for assessment purposes.

RNP Road Noise Policy (DECCW, 2011).

Tonality Noise containing a prominent frequency or frequencies characterised by definite pitch.

Vibration The variation of the magnitude of a quantity which is descriptive of the motion or position of a mechanical system, when the magnitude is alternately greater and smaller than some average value or reference. Vibration can be measured in terms of its displacement, velocity or acceleration. The common units for velocity are millimetres per second (mm/s).


1. Introduction

1.1 Overview

Lockhart Shire Council (‘Council’) is proposing to extend and raise the southern bank of the Lockhart Government Dam following severe flooding from Brookong Creek in October 2010 and March 2012 (the ‘proposal’).

As part of the proposal, GHD Pty Ltd (GHD) was engaged by Council to prepare an Review of Environmental Factors which includes an assessment of potential noise and vibration impacts from the construction of the levee bank.

Background noise monitoring was undertaken at one location with consideration to the NSW Industrial Noise Policy (INP) (EPA, 2000).The noise and vibration impact assessment has been undertaken with consideration to the following guidelines:

Assessing Vibration: a Technical Guideline (DEC, 2006)

Interim Construction Noise Guideline (ICNG) (DECC, 2009)

Road Noise Policy (RNP) (DECCW, 2011).

1.2 Scope

The noise impact assessment scope of works was as follows:

Initial desktop review and site visit to identify sensitive receivers

Long term background noise monitoring was undertaken for a period of one week at one location representative of the surrounding sensitive receivers in the suburban area to the south west of the proposal

The noise monitoring data was used to establish construction noise criteria based on the Interim Construction Noise Guideline (2009). Weather data over the monitoring period was obtained from the nearest Bureau of Meteorology Automated Weather Station

Construction noise impacts were assessed with consideration to the Interim Construction Noise Guideline as follows:

– Construction noise modelling was undertaken to predict the impacts at the sensitive receivers

– Impacts against the construction noise criteria were assessed.

Construction vibration impacts were assessed against Assessing Vibration: A Technical Guideline

Construction traffic noise impacts were assessed against the NSW Road Noise Policy criteria based on supplied traffic generation and existing traffic volumes.

Where required, mitigation measures were specified to minimise impact at sensitive receivers.

2. Existing environment

The proposal is located to the north-east of Lockhart, south of the Brookong creek. The location of the proposed Levee is shown in Figure 1. The land use surrounding the site is rural, with residential receivers located to the south and south-west of the construction zone.

2.1 Sensitive receivers

Noise and vibration sensitive receivers are defined based on the type of occupancy and the activities performed in the land use. Sensitive noise and vibration receivers could include:

residences

educational institutes

hospitals and medical facilities

places of worship

passive and active recreational areas such as parks, sporting fields, golf courses (Note that these recreational areas are only considered sensitive when they are in use or occupied)

commercial or industrial premises.

Residential receivers have been identified to the south and south-west of the construction zone. Other sensitive receivers (such as educational institutes, places of worship and hospitals) within Lockhart are located over 1 kilometre from the construction zone. These receivers are also acoustically shielded by preceding rows of houses. The only non-residential receiver considered in the assessment is the Church on Ferrier Street.

Sensitive receivers selected for modelling and assessment purposes are detailed in Table 2-1 and shown graphically in Figure 1.

2.1 Background noise monitoring methodology

Noise monitoring was undertaken from 12 January to 19 January 2017 in the backyard of 7 Galore Street, Lockhart, located south of the Government Dam site. The monitoring location is shown in Figure 1.

Noise monitoring was undertaken to determine background noise levels for the noise assessment. Monitoring was undertaken at the above location, which was secure from theft and vandalism and considered representative of the ambient environment in the vicinity of the proposal site.

Noise monitoring was undertaken using a Rion NL-52 environmental noise logger within calibration. The instrument was programmed to accumulate environmental noise data continuously over sampling periods of 15 minutes for the entire monitoring period.

Prior to deployment, a calibration check was performed on the noise monitoring equipment using a sound level calibrator with a sound pressure level of 94 dBA at 1 kHz. At completion of the measurements, the meter’s calibration was re-checked to ensure the sensitivity of the noise monitoring equipment had not varied. The equipment was found to be within the acceptable tolerance of ± 0.5 dBA.

The data collected by the equipment was downloaded and analysed, and any invalid data removed. Invalid data generally refers to periods of time where average wind speeds were greater than 5 m/s (at 10 m, or 7 m/s at microphone height), or when rainfall occurred. Meteorological data for the monitoring period was obtained from the nearest Bureau of Meteorology Weather Station to the site, at Narrendra Airport.

2.2 Summary of noise monitoring results

Rating background levels and ambient noise levels are summarised in Table 2-3. Daily noise level charts for the entire monitoring period are presented in Appendix A. A detailed description of the acoustic terms can be found in the glossary at the start of this report.

The ambient noise levels are typical of a rural area with low background noise levels and few sources of artificial noise.

3. Compliance criteria

The noise and vibration compliance criteria during operation and construction of the Proposal are presented in the following section as follows:

Construction noise criteria (Section 3.1)

Construction vibration criteria (Section 0)

3.1 Construction noise criteria

3.1.1 Construction noise management levels

The ICNG outlines standard hours for construction activities as Monday to Friday: 7 am to 6 pm, Saturday: 8 am to 1 pm and no work on Sundays or public holidays. The ICNG acknowledges that the following activities have justification to be undertaken outside the recommended standard construction hours assuming that all reasonable and feasible mitigation measures are implemented to minimise the impacts to the surrounding sensitive land uses:

the delivery of oversized plant or structures that police or other authorities determine to require special arrangements to transport along public roads

emergency work to avoid the loss of life or damage to property, or to prevent environmental harm

works where a proponent demonstrates and justifies a need to operate outside the recommended standard construction hours

works which maintain noise levels at receivers to below the noise management levels outside of the recommended standard construction hours.

Table 3-1 and Table 3-2 detail the ICNG construction noise management levels at sensitive land uses and residences near the proposal, respectively, where:

The noise affected noise management level represents the point above which there may be some community reaction to noise. Where the predicted or measured LAeq(15min) is greater than the noise affected level, the proponent should apply all feasible and reasonable work practices to meet the noise affected level. The proponent should also inform all potentially impacted residents of the nature of works to be carried out, the expected noise levels and duration, as well as contact details

The highly noise affected level represents the point above which there may be strong community reaction to noise. Where noise is above this level, the relevant authority (consent, determining or regulatory) may require respite periods by restricting the hours that the very noisy activities can occur, taking into account:

– times identified by the community when they are less sensitive to noise (such as before and after school for works near schools, or mid-morning or mid-afternoon for works near residences)

– if the community is prepared to accept a longer period of construction in exchange for restrictions on construction times.

A strong justification would typically be required for works outside the recommended standard hours. The proponent should apply all feasible and reasonable work practices to meet the noise affected level. Where all feasible and reasonable practices have been applied and noise is more than 5 dBA above the noise affected level, the proponent should consult with the community.

3.1.3 Traffic noise criteria

The Road Noise Policy provides traffic noise target levels for residential receivers in the vicinity of existing roads (Table 3-4). These levels are applied to construction works to identify potential impacts as a result of noise produced by construction traffic and the potential for reasonable and feasible mitigation measures to be applied.

The application notes1 for the Road Noise Policy state that “for existing residences and other sensitive land uses affected by additional traffic on existing roads generated by land use developments, any increase in the total traffic noise level as a result of the development should be limited to 2 dB above that of the noise level without the development. This limit applies wherever the noise level without the development is within 2 dB of, or exceeds, the relevant day or night noise assessment criterion.”

If road traffic noise increases as a result of construction work lies within 2 dB(A) of current levels then the objectives of the Road Noise Policy are met and no specific mitigation measures would be required.

3.2 Construction vibration criteria

3.2.1 Human comfort

Vibration has been assessed based on the criteria in Assessing Vibration: a technical guideline. British Standard (BS) 6472 – 1992, Guide to Evaluation of Human Exposure to Vibration in Buildings (1 Hz to 80 Hz) is recognised by the guideline as the preferred standard for assessing the ‘human comfort criteria’.

Typically, construction activities generate ground vibration of an intermittent nature. Intermittent vibration is assessed using the vibration dose value. Acceptable values of vibration dose are presented in Table 3-5 for sensitive receivers.

1http://www.environment.nsw.gov.au/noise/roadnoiseappnotes.htm 12 December 2012


Whilst the assessment of response to vibration in BS 6472-1:1992 is based on vibration dose value and weighted acceleration, for construction related vibration, it is considered more appropriate to provide guidance in terms of a peak value, since this parameter is likely to be more routinely measured based on the more usual concern over potential building damage.

Humans are capable of detecting vibration at levels which are well below those causing risk of damage to a building. The degrees of perception for humans are suggested by the vibration level categories given in BS 5228.2 – 2009, Code of Practice Part 2 Vibration for noise and vibration on construction and open sites – Part 2: Vibration, as shown below in Table 3-6.

Table 3-5 Human comfort intermittent vibration limits (BS 6472-1992)

Night 0.13 0.26

Table 3-6 Guidance on effects of vibration levels for human comfort

(BS 5228.2 – 2009)

Vibration level Effect

0.14 mm/s Vibration might be just perceptible in the most sensitive situations for most vibration frequencies associated with construction.

0.3 mm/s Vibration might be just perceptible in residential environments.

1.0 mm/s It is likely that vibration at this level in residential environments will cause complaints, but can be tolerated if prior warning and explanation has been given to residents.

10 mm/s Vibration is likely to be intolerable for any more than a very brief exposure.

3.2.2 Cosmetic damage

BS 7385 Part 2– 1993 Evaluation and measurement for vibration in buildings Part 2 provides criteria to assess the effects of transient vibration on structures. The cosmetic damage criteria transient vibration are detailed in Table 3-7, noting a 50% reduction for continuous vibration in the case of dynamic magnification due to resonance. DIN4150 has criteria for particular reference for heritage structures however note BS7385 states the following:

“A building of historical value should not (unless it is structurally unsound) to be assumed to be more sensitive.”

Important buildings which are difficult to repair (such as heritage buildings) may require special consideration on a case-by-case basis particularly if a dilapidation report indicates they are structurally unsound. The DIN vibration criteria is presented below in Table 3-8 for consideration for the case of any identified structurally unsound buildings.

4.1.1 Construction timing

It is anticipated that the construction works for the proposal would be undertaken during the recommended standard construction hours adopted as follows:

Monday to Friday: 7 am to 6 pm.

Saturday: 8 am to 1 pm.

Sundays and Public Holidays: no work.

It is anticipated that construction of the proposal would take about three months.

4.1.2 Construction process

– Unsuitable materials that cannot be re-used would be transported to licensed disposal facilities

Culvert Drainage work, including:

– Remove soil, vegetable matter and other debris from the vicinity of the pipes.

– Construct two new pipe culverts adjacent to the existing pipe culvert. This may include excavation of road material adjacent to the existing pipe, placement of bedding material, installation of precast pipes, placement and compaction of gravel, and installation of concrete headwalls, and outlet protection gabions.


– Regrade culvert inlet and outlet channels within the road reserve to permit free drainage where required.

– Replacing existing line-marking, raised pavement markers, guideposts and signage.

Channel and Berm Construction, including:

– Remove soil, vegetable matter and other debris from the vicinity of the channel footprint.

– Undertake earthworks to shape the channel and berm, including cut and fill operations and compaction of the finished surfaces.

– Undertake topsoil and seeding of the channel and berm

Potential relocation of Telstra underground cabling where identified in the drawings and on site as necessary.

Site clean-up and rehabilitation, including:

– Removing excess material from stockpile sites

– Removing temporary stockpile sites

– Revegetating disturbed areas

– Removing temporary erosion and sedimentation controls

– Removing temporary traffic controls

– Reinstate fences and gates as appropriate.

4.2 Construction noise impacts

4.2.1 Construction noise modelling methodology

Construction scenarios have been created based on construction equipment likely to be operating for the relevant construction activities. Noise levels for equipment have been obtained from AS2436 – 2010 Guide to noise and vibration control on construction, demolition and maintenance sites unless otherwise stated and are provided in Table 4-1. Other equipment than that modelled may be used assuming they would produce similar noise emissions.

For each construction scenario, the noise levels at the modelled sensitive receivers in the vicinity of the proposal have been predicted.

Noise modelling was undertaken using SoundPLAN (v7.4). SoundPLAN is a computer program for the calculation, assessment and prognosis of noise exposure. SoundPLAN calculates environmental noise propagation according to ISO 9613-2 ‘Acoustics – Attenuation of sound during propagation outdoors’.

The following noise modelling assumptions were made:

surrounding land was modelled assuming a mixture of hard and soft ground with a ground absorption coefficient of 0.75

atmospheric absorption was based on an average temperature of 10 °C and an average humidity of 70%

atmospheric propagation conditions were modelled with noise enhancing wind conditions for noise propagation (downwind conditions) or equivalently a well-developed moderate ground based temperature inversions

modelled scenarios take into account the shielding effect from surrounding buildings and structures on and adjacent to the site. Attenuation from built up areas was included away from the site


noise sources were modelled assuming noise propagation in the 500 Hz octave band frequency as per ISO 9613-2

noise sources for each scenario are in some cases modelled at different locations. As such the noise modelling assesses the noise source at multiple locations and takes the maximum LAeq received noise level.

4.2.2 Construction noise impacts

Construction noise levels have been predicted during standard construction hours at modelled sensitive receivers for each construction scenario. The noise levels are tabulated in Appendix B. Impacts to sensitive receivers have the potential to occur where sensitive receivers experience noise higher than the relevant construction noise management level.

The predicted number of receivers exceeding the relevant construction noise management levels is presented in Table 4-2.

Table 4-2 Number of receivers exceeding the construction noise

management levels

Construction noise management level

Backhoe Excavator Front end loader Grader Roller Scraper Truck/water cart

40 (standard hours) 50 68 100 90 74 101 68

The results indicate that, without mitigation, construction noise may exceed the noise management levels at sensitive receivers during standard construction hours. The worst affected receivers lie along Galore Street, with a direct line of sight to the construction zone.

The highly noise affected criteria is not predicted to be exceeded at any identified sensitive receivers.

Noise impacts at sensitive receivers have been classified based on the Construction Noise Strategy (TfNSW, 2012) into the following categories relative to the background noise levels:

Clearly audible: 10 to 20 dBA above the day time rating background level of 30 dBA

Moderately intrusive: 20 to 30 dBA above the day time rating background level of 30 dBA

Highly intrusive: More than 30 dBA above the day time rating background level of 30 dBA.


The number of receivers within these construction noise impact zones (as defined above) are presented in Table 4-3.

Table 4-3 Number of receivers within identified construction noise impact

zones

Moderately intrusive 13 24 34 29 26 41 24

Highly intrusive 1 2 13 4 2 21 2

For the noisiest construction equipment (scraper), the above noise impact zones have been mapped and are shown in Figure 2.

The magnitude of off-site noise impact will be dependent upon a number of factors including the intensity and location of activities, the type of equipment used, the background noise levels during the construction period, the prevailing weather conditions and the movement of construction equipment within the construction corridor.

Additional mitigation measures and safeguards detailed in section 5 have been recommended, where feasible and reasonable, to reduce noise impacts.

4.2.3 Site compounds

A temporary site compound and stockpile site would be established within the Government Dam site.

In general, the facilities at the compound site would include toilet facilities, secure bunded areas for the storage of fuels and chemicals and designated parking and waste management areas. A site office will be established if required.

The stockpile site would be required for storing construction materials. The stockpile site would be located away from the residences on Galore Street to minimise noise impacts.

The stockpile site would be temporary for the period of construction and would be rehabilitated before the completion of construction.

Temporary noise impacts associated with heavy vehicle movements and equipment laydown may occur on residential receivers located on Galore Street. The noise impacts are not expected to be significant in duration.

4.3 Construction traffic

The proposal would generate a number of heavy vehicle movements through the transport of machinery, fuel, general provisions and materials. The majority of vehicle movements would be for the transport of spoil form Treasure Street to the Government Dam site.

The number of heavy vehicle movements required to transport spoil from Treasure Street to the proposal site would be approximately 100, with two trucks carting about 50 loads of spoil each day over the duration of the construction period.


A significant increase in traffic volumes would be needed in order to increase road traffic noise by 2 dBA (a doubling in traffic corresponds to an approximate 3 dBA increase).

Construction access to the proposal site would be via Lockhart – Collingullie Road and local roads in Lockhart. There are forecast to be 18 truck movements per hour using this route. There is the potential for exceedances to the road noise criteria at approximately 20 m from the road. Existing traffic data is not available therefore the increase in traffic noise cannot be calculated however it is likely that the vehicle movements would not be significant when compared with the existing vehicle numbers in the area. As a result, significant noise impacts from construction traffic movements are not expected however the mitigation measures recommended in Section 5 should be considered where feasible and reasonable.


4.4 Construction vibration

Table 4-4 outlines typical vibration levels for vibration generating equipment associated with the construction of the proposal. Potential vibration impacts would be limited to the construction period.

4.4.1 Construction vibration impacts

Energy from equipment is transmitted into the ground and transformed into vibration, which attenuates with distance. The magnitude and attenuation of ground vibration is dependent on the following:

the efficiency of the energy transfer mechanism of the equipment (i.e impulsive; reciprocating, rolling or rotating equipment)

the frequency content

the impact medium stiffness

the type of wave (surface or body)

the ground type and topography.

Safe working buffer distances to comply with the human comfort, cosmetic damage and heritage structural damage criteria have been provided in Table 4-5.

Table 4-5 Vibration safe working buffer distances, m

Activity1 Human comfort Structural damage

Heritage building/structure

Standard dwellings




Note 1: These distances have been sourced from the Construction Noise Strategy (TfNSW, 2012)

4.4.1.1 Structural damage

With consideration to the building damage criteria for typical buildings, the expected magnitude of ground vibrations should not be sufficient to cause damage to standard buildings within 12 metres of the works or heritage buildings within 24 m of the works. The impact will depend on the size of equipment used.

No standard dwellings or heritage structures have been identified within the safe working buffer distances. Specific structural damage vibration mitigation measures are not required for the proposal.


4.4.1.2 Human comfort

The nearest residential receivers are over 50 m from the proposal area. Human comfort impacts from the proposal are not anticipated for vibratory rollers up to 6 tonnes. Specific vibration mitigation measures are not required for the proposal.

General mitigation measures and safeguards are provided in section 5.


5. Mitigation

Construction activities are predicted to exceed the construction noise management levels for the proposal. The measures provided below would be implemented to minimise potential construction noise impacts. Consultation and cooperation with the neighbours of the site will assist in minimising uncertainty, misconceptions and adverse reactions to noise.

Construction noise mitigation measure

Site inductions Inductions for the work crew would include the specific noise issues and mitigation measures required for the site. The induction would include:

all relevant project specific and standard noise mitigation measures

relevant approval conditions

permissible hours of work

location of nearest sensitive receivers

construction employee parking areas

designated loading/ unloading areas and procedures

site opening/closing times (including deliveries)

behavioural practices including:





– avoiding dropping materials from height and avoiding metal to metal contact on material.

Where the predicted and/or measured construction noise is greater than the noise affected level, works would be conducted in accordance with the ICNG and all reasonable and feasible practices would be undertaken to minimise noise.


Site setup and dismantling would occur during standard work hours, reducing noise impacts to sensitive receivers where possible. The site setup would seek to maximise the distance between plant and equipment and any residences and other noise sensitive receivers where practicable. For example, vehicle movements and generator storage would be located as far as possible from residences.

Use quieter noise emitting construction methods where practicable.

Machines found to produce excess noise compared to industry best practice would be removed from the site or stood down until repairs or modifications can be made.

Ensure that truck engine brakes usage is minimised when entering or leaving the work sites or work areas adjacent to residential properties and on construction traffic routes.


Construction noise mitigation measure

Any noise complaints would be addressed immediately in accordance with a standard resolution procedure. Property owners/occupiers potentially impacted by the construction works would be informed in advance of the proposed work and provided a contact phone number for any complaints or concerns during the construction period


6. Conclusion

Construction noise impacts associated with the Lockhart Government Dam extension have been assessed.

Construction activities during recommended standard construction hours are predicted to exceed the noise affected construction noise management level at sensitive receivers for most construction activities. Reasonable and feasible construction noise mitigation measures have been recommended, which would minimise noise impacts at potentially affected receivers.

There is potential for exceedances to the road noise criteria at approximately 20 m from the road due to construction traffic noise. However it is likely that the vehicle movements would not be significant when compared with the existing vehicle numbers in the area. As a result, significant noise impacts from construction traffic movements are not expected.

Human comfort and structural damage vibration impacts from the proposal are not anticipated. Specific vibration measures are not required for the proposal.

The proposal should be acceptable from an acoustic perspective assuming the recommended mitigation measures are implemented.

Travelling Stock Reserves (TSRs)

Travelling Stock Reserves (TSRs) are parcels of Crown land reserved under legislation for use by travelling stock. Local Land Services is responsible for the care, control and maintenance of almost 500,000ha of TSRs in NSW.

TSRs provide pasture reserves for travelling or grazing stock. These reserves can be beneficial in times of drought, bushfire or flood. They are also used for public recreation, apiary sites and for conservation.

Local Land Services manages the land to strike a balance between the needs of travelling or grazing stock and the conservation of native species.

The role of Local Land Services role in managing TSRs includes:

Authorising and monitoring stock, recreation and apiary site use

Controlling noxious weeds

Controlling pest animals and insects

Provision and maintenance of fencing, watering points and holding yards

Consideration of land management and animal health legislation.

Local Land Services has developed the first draft state‐wide planning framework for TSRs to support the future management of this land. We are now keen to hear from the public with their opinions on how to manage TSRs in the future. We want to understand the values people hold important for TSRs, including biodiversity and Aboriginal cultural heritage values.

The draft state‐wide framework allows for the development of TSR regional management plans to facilitate more consistent and transparent management, resourcing and reporting.

Aboriginal objects: Aboriginal objects are physical evidence of the use of an area by Aboriginal people. They can also

be referred to as 'Aboriginal sites', 'relics' or 'cultural material'.

Aboriginal objects include:

* Physical objects, such as stone tools, Aboriginal‐built fences and stockyards, scarred trees and the remains of fringe camps * Material deposited on the land, such as middens * The ancestral remains of Aboriginal people.

Handicrafts made by Aboriginal people for sale are not 'Aboriginal objects' under the NPW Act.

Known Aboriginal objects and sites are recorded on OEH's Aboriginal Heritage Information

Management System (AHIMS). If you find a site you should report it to us.

Protecting Aboriginal objects and places:

You will need to exercise due diligence in determining whether your actions will harm Aboriginal

objects. The Due Diligence Code of Practice for the Protection of Aboriginal Objects in NSW

http://www.environment.nsw.gov.au/resources/cultureheritage/ddcop/10798ddcop.pdf

This link will explain and provide practical guidance about what due diligence means. Anyone who

exercises due diligence in determining that their actions will not harm Aboriginal objects has a

defence against prosecution for the strict liability objects offence if they later harm an Aboriginal

object.

An Aboriginal Heritage Impact Permit (AHIP) can be issued by OEH under Part 6 of the NPW Act

where harm to an Aboriginal object or Aboriginal place cannot be avoided. An AHIP is a defence to

a prosecution for harming Aboriginal objects and/or Aboriginal places if the harm was authorised

by the AHIP and the conditions of that AHIP were not contravened.

Find out about AHIPs, due diligence and care agreements see Information on Aboriginal Heritage

Impact Permits. http://www.environment.nsw.gov.au/licences/Section87Section90.htm

5

Purpose of code of practice for Due Diligence.

This code of practice is to assist individuals and organisations to exercise due diligence when

carrying out activities that may harm Aboriginal objects and to determine whether they should

apply for consent in the form of an Aboriginal Heritage Impact Permit (AHIP). The National Parks

and Wildlife Act 1974 (NPW Act) provides that a person who exercises due diligence in

determining that their actions will not harm Aboriginal objects has a defence against prosecution

for the strict liability offence if they later unknowingly harm an object without an AHIP.

The NPW Act allows for a generic code of practice to explain what due diligence means. Carefully

following this code of practice, which is adopted by the National Parks and Wildlife Regulation

2009 (NPW Regulation) made under the NPW Act, would be regarded as ‘due diligence’. This code

of practice can be used for all activities across all environments.

This code sets out the reasonable and practicable steps which individuals and organisations need

to take in order to: 1 identify whether or not Aboriginal objects are, or are likely to be, present in

an area 2 determine whether or not their activities are likely to harm Aboriginal objects (if

present) 3 determine whether an AHIP application is required.

If Aboriginal objects are present or likely to be present and an activity will harm those objects,

then an AHIP application will be required. Information about the permits and how to apply for

them can be obtained through the Department of Environment, Climate Change and Water

(DECCW) website at

www.environment.nsw.gov.au/licences/index.htm.

Site Report and Recommendations.

22/12/2016

Lockhart Dam, Lockhart, NSW.

On my site inspection on the 22/12/2016, I inspected a large area known as Lockhart Dam at Lockhart NSW. The place instantly felt welcoming and with the feeling that many people have visited and lived at this inviting area. This area I believe was inhabited by Wiradjuri people and was a place where many camped and lived over a long period of time.

In this area, I noticed many species of bird including Grass Parrots, Willy Wag Tail, Eagles, Rainbow Lorikeet, Galah, Cockatoo and White Winged Chough to name a few.

The water way also contains many water animals including Yabby, small fish, Dragon Flies and a large array of Butterflies and bees.

The area also has good regrowth of salt bush, some native water rush plants and young tree suckers.

The water way and remaining pockets of water holes are beginning to choke up with a plant known as, Water Primrose, all though not a weed, it needs to be under control and allow the natural flow of the creek when rain does come again.

This area has been heavily impacted by cattle and machinery. Previously recorded Aboriginal sites have been damaged and driven over, this needs to stop and actions taken to stop this from happening again.

In this area, a proposed levy bank may be constructed which will assist in flood mitigation that will greatly help the local community in times of heavy rain. I would insist that all Aboriginal Sites are treated with respect and that any work in this area take into consideration any impact on these very important sites. I would also ask that cattle and horse are to be excluded from this area and that protective fencing be erected around the scar trees.

I would also ask for the planting of native trees that would enhance the area for both people and bird life. Some Bull Oak trees would also add to the area and may assist in the habitat for Glossy Black Cockatoo.

A construction of walking tracks in this area would help to enhance visitor engagement as well as some bird hides where people who enjoy watching and photographing birds can sit and enjoy what Wiradjuri people have done for over 60,000 years.

This would add another dimension to attracting people and wildlife to Lockhart which in turn will add to the local economy.

I would be happy to assist when the plans are draw for the levy bank in the future with regards to Aboriginal site protection.

Procedures to work around Aboriginal sites can be found at this link, http://www.aboriginalheritage.org/sites/legislation/

Travelling Stock Reserves (TSRs)

Travelling Stock Reserves (TSRs) are parcels of Crown land reserved under legislation for use by travelling stock. Local Land Services is responsible for the care, control and maintenance of almost 500,000ha of TSRs in NSW.

TSRs provide pasture reserves for travelling or grazing stock. These reserves can be beneficial in times of drought, bushfire or flood. They are also used for public recreation, apiary sites and for conservation.

Local Land Services manages the land to strike a balance between the needs of travelling or grazing stock and the conservation of native species.

The role of Local Land Services role in managing TSRs includes:

Authorising and monitoring stock, recreation and apiary site use

Controlling noxious weeds

Controlling pest animals and insects

Provision and maintenance of fencing, watering points and holding yards

Consideration of land management and animal health legislation.

Local Land Services has developed the first draft state‐wide planning framework for TSRs to support the future management of this land. We are now keen to hear from the public with their opinions on how to manage TSRs in the future. We want to understand the values people hold important for TSRs, including biodiversity and Aboriginal cultural heritage values.

The draft state‐wide framework allows for the development of TSR regional management plans to facilitate more consistent and transparent management, resourcing and reporting.

Aboriginal objects: Aboriginal objects are physical evidence of the use of an area by Aboriginal people. They can also

be referred to as 'Aboriginal sites', 'relics' or 'cultural material'.

Aboriginal objects include:

* Physical objects, such as stone tools, Aboriginal‐built fences and stockyards, scarred trees and the remains of fringe camps * Material deposited on the land, such as middens * The ancestral remains of Aboriginal people.

Handicrafts made by Aboriginal people for sale are not 'Aboriginal objects' under the NPW Act.

Known Aboriginal objects and sites are recorded on OEH's Aboriginal Heritage Information

Management System (AHIMS). If you find a site, you should report it to us.

Protecting Aboriginal objects and places:

You will need to exercise due diligence in determining whether your actions will harm Aboriginal

objects. The Due Diligence Code of Practice for the Protection of Aboriginal Objects in NSW

http://www.environment.nsw.gov.au/resources/cultureheritage/ddcop/10798ddcop.pdf

This link will explain and provide practical guidance about what due diligence means. Anyone who

exercises due diligence in determining that their actions will not harm Aboriginal objects has a

defence against prosecution for the strict liability objects offence if they later harm an Aboriginal

object.

An Aboriginal Heritage Impact Permit (AHIP) can be issued by OEH under Part 6 of the NPW Act

where harm to an Aboriginal object or Aboriginal place cannot be avoided. An AHIP is a defence to

a prosecution for harming Aboriginal objects and/or Aboriginal places if the harm was authorised

by the AHIP and the conditions of that AHIP were not contravened.

Find out about AHIPs, due diligence and care agreements see Information on Aboriginal Heritage

Impact Permits. http://www.environment.nsw.gov.au/licences/Section87Section90.htm

5

Purpose of code of practice for Due Diligence.

This code of practice is to assist individuals and organisations to exercise due diligence when

carrying out activities that may harm Aboriginal objects and to determine whether they should

apply for consent in the form of an Aboriginal Heritage Impact Permit (AHIP). The National Parks

and Wildlife Act 1974 (NPW Act) provides that a person who exercises due diligence in

determining that their actions will not harm Aboriginal objects has a defence against prosecution

for the strict liability offence if they later unknowingly harm an object without an AHIP.

The NPW Act allows for a generic code of practice to explain what due diligence means. Carefully

following this code of practice, which is adopted by the National Parks and Wildlife Regulation

2009 (NPW Regulation) made under the NPW Act, would be regarded as ‘due diligence’. This code

of practice can be used for all activities across all environments.

This code sets out the reasonable and practicable steps which individuals and organisations need

to take in order to: 1 identify whether or not Aboriginal objects are, or are likely to be, present in

an area 2 determine whether or not their activities are likely to harm Aboriginal objects (if

present) 3 determine whether an AHIP application is required.

If Aboriginal objects are present or likely to be present and an activity will harm those objects,

then an AHIP application will be required. Information about the permits and how to apply for

them can be obtained through the Department of Environment, Climate Change and Water

(DECCW) website at

www.environment.nsw.gov.au/licences/index.htm.

Site Report and Recommendations.

09/03/2017

Cemetery Reserve TSR, Lockhart, NSW.

On my site inspection on the 09/03/2017, I inspected an area known as Cemetery Reserve TSR at Lockhart NSW.

The area also has some regrowth of salt bush and Burri (Boree Trees) and young tree suckers.

These trees need protection and perhaps the area would benefit from more plantings.

This area has been heavily impacted by cattle and machinery. Over many years this place was used for thousands of sheep and cattle so the area is badly in need of restoration.

I would suggest that the planting of native trees that would enhance the area for both people and bird life would greatly assist in this areas restoration. Some Bull Oak trees would also add to the area and may assist in the habitat for Glossy Black Cockatoo (Yuyung)

In this area, a proposed levy bank may be constructed which will assist in flood mitigation that will greatly help the local community in times of heavy rain. I would insist that all Aboriginal Sites are treated with respect and that any work in this area take into consideration any impact on these very important sites. I would also ask that cattle and horse are to be excluded from this area and that protective fencing be erected around the scar trees.

A construction of walking tracks in this area would help to enhance visitor engagement as well as some bird hides where people who enjoy watching and photographing birds can sit and enjoy what Wiradjuri people have done for over 60,000 years.

This would add another dimension to attracting people and wildlife to Lockhart which in turn will add to the local economy.

I would be happy to assist when the plans are draw for the levy bank in the future with regards to Aboriginal site protection.

Hi Leigh, Further to our telephone conversation this afternoon I can confirm that the proposed levee at the site known as Government Dam (Brookong Creek) on the northern outskirts of Lockhart would be exempt from requiring a Floodwork Approval on the basis that (as you have advised);

1. Council are the proponents; and 2. Development Consent under EP & A Act will be sought.

It is understood WMA Water have produced a flood risk plan in accordance with the Floodplain Development Manual. For your file. Regards Clare Clare Purtle Senior Water Regulation Officer Important: As a result of NSW water reforms, many functions previously provided by DPI Water have transferred to WaterNSW, effective 1 July. These functions include customer interactions for licencing, compliance and billing – as well as all in‐field services and metering operations. Customers will experience streamlined, more convenient and efficient services. Over the coming months, you will begin to see WaterNSW branded materials for these services.

Hi Leigh, Your enquiry has ended up with me.

I have attached a document regarding exemptions. Can you advise your thinking behind your thought that this bank is exempt. Is the bank for the protection of the town? Will it have Development consent? I Council the proponent? This information will help me provide a better response to you. Regards Clare

Dear Bob,

I had directed my below initial enquiry to Tim Smith, not realising that he had moved on. I was given you contact details from the Queanbeyan office and was wondering if you might be able to help with the below enquiry.

GHD have been working with Lockhart Shire Council to assist them in developing flood management options as a result of extensive flooding in the shire in March 2012 and October 2010.

WMAwater prepared a Floodplain Risk Management Study and Plan for Lockhart Shire Council in 2014. GHD has since been working with Council to further develop the proposed management options developed in the report prepared by WMAwater.

We are currently preparing an REF for one of these options. The option involves construction of a levee at a site known as Government Dam on Brookong Creek on the northern outskirts of Lockhart. I wanted to check with you about the requirement for a flood work approval under the Water Management Act 2000 (replacing the controlled works under the Water Act 1912).

From what I can tell, I think it may be exempt from requiring a flood work approval. However, I’d like to get your opinion on this if possible. I will still forward through a formal consultation letter, but just wanted to gauge your opinion in the interim.

Attached is a map of the proposed location of the Government Dam levee. If you require a copy of the Floodplain Risk Management Study, please let me know and I can forward it via a separate large file transfer.

Thank you for your assistance on this matter
