1. Introduction 1.1 Proposal identification
Lockhart Shire Council (Council) is proposing to construct a pressure sewerage system at The
Rock. The proposal will connect properties in the existing onsite septic (or aerated) systems to a
pressure sewer reticulated network.
The pressure sewerage system has been divided into two stages; Stage A and Stage B. This
Review of Environmental Factors (REF) is for the construction of Stage A of the system Figure
1.1)
For the purposes of this assessment, the following definitions are used:
The ‘proposal’ (being assessed by this REF) refers to the proposed construction of the
pressure sewerage system (see Figure 1.1)
The ‘proposal site’ refers to the area required for the construction of the proposal,
including construction activities and construction vehicle access. The proposal site also
includes the site compound and stockpile sites and any other areas that would be
disturbed by the proposal
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 protective 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.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 2
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.

2. Needs and options considered 2.1 Need for the proposal
The properties located south of the Olympic Highway at The Rock are currently serviced by
onsite septic or aerated sewage systems. These systems are constrained by the requirement to
maintain constant grades and during high rainfall events. Excessive water from rainfall runoff
can significantly affect the performance of the receiving sewage treatment plants and can
overload transfer sewage pumping stations.
The objective of the proposal is to provide an efficient and cost-effective reticulated sewage
service for the properties located in the Stage A boundary of the proposal and to decommission
the existing onsite septic and aerated systems.
2.2 Alternatives and options considered
Two options were considered for the proposal; the do nothing option and the proposed
construction of a pressure sewerage system.
The do nothing option would involve leaving the existing onsite septic and aerated sewage
systems as is. This option would not improve the efficiency of the sewage service provided to
residents and would not provide a cost-effective benefit, as currently residents are responsible
for emptying their own systems. This option would not meet the objectives of the proposal and
is therefore not the preferred option.
2.2.1 Preferred option
The preferred option is the construction of the pressure sewerage system, due to the provision
of an efficient and cost-effective reticulated sewage service for the properties located in the
Stage A boundary of the proposal.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 5
3. Description of the proposal 3.1 The proposal
It is proposed to construct a pressure sewerage system, south of the Olympic Highway at The
Rock, to provide properties with an efficient and cost-effective sewage service. The proposal
includes installation of the pressure sewer mains progressively along the alignment, with
connection of the existing residences to the system and discharging into the existing gravity
sewer system manhole at Cornwall Street (see Figure 1.1 and Appendix E).
Stage A of the pressure sewerage system is bounded by Milne Road, Mangoplah Road, Emily
Street and the Olympic Highway and consists of about 54 existing properties plus the Kings
Own Hotel-Motel. The existing properties are currently serviced by onsite sewage systems
which would be abandoned upon commission of the new reticulated system.
The proposal would require the underboring of the Olympic Highway, managed by Roads and
Maritime Services (Roads and Maritime) and the Main Southern Railway, managed by the
Australian Rail Track Corporation (ARTC) in the north-western section of the proposal site.
A designated compound site is not required for the proposal. The existing Council depot at The
Rock would be utilised for storage of materials and compound facilities.
It is anticipated that the proposal would commence in June 2017, with construction to be
completed by December 2017. It is expected that construction would be completed on one to
two properties per day.
3.2 Design
The proposal has been designed to connect the existing and any future dwellings within the
Stage A boundary to a pressure sewerage system for discharge into the existing gravity sewer
system on the northern side of the Olympic Highway. Dwellings on the northern side of the
highway are serviced by an existing pressure sewerage system. Stage A has been designed to
accommodate the connection of an additional 237 future lots.
Key features of the proposal include:
Polyethylene pipe with diameter between 50 millimetres and 75 millimetres
Air release valves at significant high points, enclosed in a fibreglass kiosk and surrounded
by concrete filled pipe bollards
Flushing points, including an on/off switch for flushing the system when required and non-
return valves to prevent sewage back-flow
Isolation valves, to isolate individual systems from the mains if required
Boundary kit, including grinder pump for macerating sewage into fine watery slurry for
discharge and five metres of pipeline for property connection.
A barometric loop to keep odours at a reasonable level. This would be enclosed by mesh
fencing with double gates for access
Discharge into the existing gravity sewer system manhole at Cornwall Street.
The pressure sewerage system route would be excavated using open trenches where located in
road reserve and Crown Land. Designated roads, including the Olympic Highway, the Main
Southern Railway and property access along the proposal alignment would be underbored with
horizontal direction boring (HDB) methods to minimise disruption to traffic and properties during
construction. The pressure sewer mains would be installed progressively along the alignment.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 6
The construction footprint width would be about two metres either side of the pipeline with a
minimum trench width of 500 millimetres and variable pipeline depth, between 500 millimetres to
1,500 millimetres. Stage A is about 5,000 metres in total length.
The pipe would be located within the table drain for part of its alignment, between Park Street
and Hill Street. The alignment would be located adjacent to existing utilities in the vicinity (see
Appendix E).
3.3 Construction activities
It is anticipated that the construction period for the pressure sewerage system will be about six
months
3.3.1 Work methodology
Construction would be undertaken by a contractor in accordance with a construction
environmental management plan (CEMP). Construction would include the following activities:
Site establishment, including:
– Establish work site boundaries, including marking of the centreline of the alignment with
survey pegs, spray paint or similar
– Install erosion and sediment controls
– Set up temporary traffic controls as required
Installation of the pressure sewerage system, including:
– Locate existing utilities within the area of the alignment, including electricity, water main
and Telstra main
– Excavation of soil from the proposed footprint where trenching would occur,
progressively along the alignment
– Underboring roads, property accesses and the Main Southern Railway, progressively
along the alignment
– Install the sewer main progressively along the alignment. This will include excavation of
soil as indicated above, placement of bedding material, installation of polyethylene pipe,
placement of compacted sand over pipe and backfill material to surface level
– Install associated infrastructure progressively along the alignment, including flushing
points, air release valves, isolation valves, boundary kits
Construction of barometric loop, including chain mesh fence with double gates for security
(see Figure 1.1)
Decommissioning of existing on site systems, including removal or crushing of existing
tanks and back-filling the hole
Site clean-up and rehabilitation, including:
– Stabilising disturbed areas
– Removing temporary erosion and sedimentation controls
– Removing temporary traffic controls.
Construction hours
It is anticipated that the proposal would typically be completed within the following hours:
Monday to Friday: 7am to 6pm
Saturday: 8am to 1pm
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 7
Sunday and Public Holidays: no work.
Plant and equipment
Plant and equipment needed for the proposal would include:
12 tonne excavator 3 tonne excavator
Tippers Skid steer
Boring machine Utility vehicles
3.3.2 Earthworks
Earthworks will include the area to be excavated for the installation of the pipeline and
associated infrastructure. The minimum width of the trench required for the pipeline is about 500
millimetres with the total length about 5,000 metres. The area of earthworks would therefore be
a minimum of about 2,500 square metres.
There is not expected to be an excess of fill from construction activities or any fill required to be
transported to the site for construction.
3.3.3 Materials
The following materials would be required for the construction of the proposal:
PE100, PN16 Polyethylene Pipe and Fittings:
– 2010 metres of 50 mm diameter
– 2000 metres of 63 mm diameter
– 915 metres of 75 mm diameter
– 255 metres of 110 mm diameter
x5 – supply and installation of flushing kits (Type 1 Light Duty Trafficable Class B)

x50 – supply of simplex E-One Extreme PSU's, including standard control panels, tanks,
grinder pumps and accessories
x50 – installation of PSU systems
Supply and install Quad E-One Extreme PSU system at hotel site
Water may be required during construction for dust suppression. If required, water would be
sources from town 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 pipeline and associated infrastructure to the proposal site.
The number of heavy vehicle movements required to transport materials from the Council depot
to the proposal site would be approximately 700 vehicle movements over the six month
construction period. This includes 380 heavy vehicle movements.
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 all public roads. 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 works along the Olympic Highway and for underboring of the
highway, traffic may be restricted to one lane. A traffic management plan would be prepared to
ensure the proposal would be unlikely to cause any significant disruption to traffic.
Construction access management
Construction access to the proposal site would be via the Olympic Highway. The Council depot,
where materials would be stored, is on the northern side of the highway, with the majority of the
proposal site located on the southern side of the highway.
3.4 Compound and stockpile site
There would be no designated site compound or stockpile site required for the proposal. The
existing Council depot at The Rock would be utilised for storage of materials and compound
facilities.
The existing facilities at the depot include a site office, toilet facilities, secure bunded areas for
the storage of fuels and chemicals, designated parking and waste management areas.
Lengths of pipe may be stored along the pipeline route, adjacent to the trench in the section that
is being constructed. Storage would be temporary for the period of construction in each section
and any disturbed areas would be rehabilitated before the completion of construction.
3.5 Public utility adjustment
There are existing utilities located along various sections of the pipeline alignment. These
include the following:
Electricity
Water main
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 9
Telstra main
Following a survey of the study area, the existing services were located and the proposal
designed in order to avoid the utilities. This was achieved by locating the alignment adjacent to
other services and the existing table drain where required.
The contractor is required to locate the services on site prior to construction and modify the
alignment to avoid the utilities if necessary.
3.6 Property acquisition
The majority of construction would take place within Council owned road reserve. A small
portion of the proposal in the north-west is located on Crown Land in the form of a disused TSR
managed by Local Land Services. Council currently leases this land. There will be no need for
land acquisition as a formal easement would not be required.

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 EP&A Act contains three parts that impose requirements for planning approval. The main
two are as follows:
Part 4 provides for control of ‘local development’ that requires development consent from
the local Council.
Part 5 provides for control of ‘activities’ that do not require approval or development
consent under Part 4.
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
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 11
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 106 of the ISEPP states that development for the purpose of a sewage reticulation
system may be carried out by or on behalf of a public authority without consent on any land. As
the proposal is for a sewage reticulation system, it can be assessed under Part 5 of the EP&A
Act.
Therefore, the proposed construction works for the sewerage system is permitted without
consent.
4.3 Local planning instruments
4.3.1 Lockhart Local Environment Plan 2012
The proposal is located within the Lockhart Local Government Area. The environmental
planning instrument applicable to the Lockhart LGA is the Lockhart Local Environmental Plan
2012 (Lockhart LEP).
The majority of the proposal is located within the RU5 – Village land use zone, with a small
portion along Mangoplah Road in the east zoned as RU1 – Primary Production, and the
Olympic Highway and Main Southern Railway zoned as SP2 – Infrastructure.
Sewerage system works are permitted in the RU5 – Village zone with consent and prohibited in
the RU1 – Primary Production and SP2 – Infrastructure zones. However, the provisions of the
Lockhart LEP do not apply to the proposal due to the application of the State Environmental
Planning Policy (Infrastructure) 2007 (ISEPP). Nevertheless, consideration has been given to
the provisions of the Lockhart LEP.
The proposal is unlikely to alter the current land uses in the land use zones in which it occurs,
as the majority of the proposal is located underground.

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 works within Crown land that
includes these activities would require approval from the NSW Department of Industry - Lands.
The Crown Land in the north-western section of the proposal site is managed by the Local Land
Services and currently lease by Council. The Local Land Services have granted approval for the
proposal (see Appendix F).
4.4.2 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 Roads and Maritime 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 Roads
and Maritime and on other roads authorities
To provide for the distribution of the functions conferred by this Act between Roads and
Maritime 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 crossing
the Olympic Highway. As Roads and Maritime is the road authority, consent is required. Roads
and Maritime have granted approval for the proposal (see Appendix F).

4.4.3 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.
4.4.4 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.
This REF concludes that the proposal would be unlikely to have a significant effect on an
Aboriginal object or Aboriginal place (see section 6.7). An Aboriginal heritage impact permit
would therefore not be required for the proposal.
4.4.5 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 5A 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.
4.5 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.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 14
This REF finds that the proposal is unlikely to have a significant impact on any matters of
national environmental significance. Accordingly, it is considered that the approval of the
Australian Government Minister for the Environment is not required and that it is not necessary
to refer the proposal to DotEE.
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 determining authority.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 15
5. Stakeholder and community consultation 5.1 Government agency involvement
5.1.1 Information provided to government agencies
REF consultation 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 20 March 2017. Agencies notified included:
Roads and Maritime
ARTC
Local Land Services.
5.1.2 Issues raised by government agencies
An email response to consultation was received from Local Land Services (see Appendix F).
There are no perceived issues for Local Land Services.
An email response was received by Roads and Maritime, including their specifications for works
in the road reserve of classified roads (see Appendix F). Comments relevant to the proposal
include:
Road crossings shall be as near as possible to right angles to the centreline of the road and
have a minimum depth of 1.0 metre below the invert of table drains, 1.2 metres below the
road surface and 750 millimetres elsewhere in the road reserve
Thrust boring or directional boring must be used for installation of any works under a state
road unless otherwise approved by Roads and Maritime. The work should be encased in a
pipe over the full width of the road formation to allow future maintenance of the works
without road disturbance
Pipes carrying pressurised water shall be sleeved under the road formation with all
associated above ground infrastructure located outside the road reserve
All materials and work methods used during the works must comply with or exceed the
relevant AS/NZ Standard, unless otherwise approved by Roads and Maritime
Traffic Control must be in accordance with “RMS Traffic Control at Worksites Manual”
The applicant shall give at least 48 hours’ notice to Roads and Maritime before
commencement of the work.
Ongoing consultation is occurring between Council and ARTC to obtain approvals required to
underbore the Main Southern Railway.
Consideration of these comments would be included in the detailed design of the proposal.
Roads and Maritime also included the licencing requirements for works on a state road (see
section 7.2 and Appendix F).
5.2 Community involvement
Council has conducted the following community consultation:
Two public meetings in 2013 and 2014, prior to development of the concept design
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 16
Letter drop to individual residences affected by the proposal
Ongoing consultation to occur includes:
Ongoing meetings with affected residents as the proposal progresses
Door knocking once the design survey has been completed
Connection to the pressure sewerage system is not compulsory for residents. Door knocking will
enable Council to discuss the benefits of connection to the system and gauge the interest of
residents prior to construction commencing.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 17
6. Environmental assessment This chapter of the REF provides a detailed description of the potential environmental impacts
associated with the construction and operation of the proposal. All aspects of the environment
potentially impacted upon by the proposal are considered. This includes consideration of the
factors specified in the guidelines Is an EIS required? (DUAP 1999) as required under clause
228(1)(b) of the Environmental Planning and Assessment Regulation 2000. The factors
specified in clause 228(2) of the Environmental Planning and Assessment Regulation 2000 are
also considered in Appendix A. Site-specific safeguards are provided to ameliorate the
identified potential impacts.
6.1 Biodiversity
6.1.1 Methodology
Desktop review
The assessment included a review of background biodiversity 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 March 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 March 2017)
DotEE (2017b) Species profile and threats database, online profiles
DPI – noxious weed declarations – Lockhart LGA control area (DPI 2017) (searched
March 2017).
Field surveys
Flora and fauna field surveys were conducted by an ecologist on 13 March 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.
Biodiversity survey effort for this proposal is summarised in Table 6.1.

Flora
Flora surveys were conducted in the study area using plot surveys (see Figure 6.1) and random
meandering transect surveys.
One 20 metre by 50 metre flora survey plot was 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 all streets 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.
Survey timing and potential limitations
Surveys were undertaken outside the optimal survey period for some species. Surveys were
undertaken in mid-March 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.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 19
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
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. The
proposal is considered to have a low potential to impact on threatened biota likely to occur due
to the limited vegetation removal required. Therefore, no assessments of the significance of
impacts were required to be prepared.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 20
Development of safeguards and management measures
Safeguards and management measures for the proposal were developed based on the site
conditions and the potential impacts of the proposal (see 6.1.4).
6.1.2 Existing environment
Flora species
Field surveys identified 58 flora species, of which 21 are native and 37 are introduced. These
species are listed in Appendix B.
The proposal predominantly occurs in roadside reserve along its length. The footprint occurs in
an area previously cleared of native vegetation with the groundcover dominated by introduced species including Wild Oats (Avena fatua), Paspalum (Paspalum dilatatum), Kikuyu Grass
(Cenchrus clandestinus) and Bromes (Bromus spp.). Commonly occurring native species
include Red-leg Grass (Bothriochloa macra), Couch (Cynodon dactylon) and Windmill Grass
(Chloris truncata). Native groundcover species are more common further from the roadside,
adjacent to the proposal site.
Mature trees occur outside the proposed footprint of the pipeline and include Yellow Box (Eucalyptus melliodora), Blakey’s Red Gum (E. blakelyi), White Box (E. albens), Grey Box (E.
microcarpa) and White Cypress Pine (Callitris glaucophylla). Planted Plane Trees (Platanus sp.)
occur along the roadside reserve of the Olympic Highway.
The proposal footprint in the Crown Land in the north-western section of the proposal site
traverses mostly cleared open paddock, which has been heavily grazed. The scattered paddock
trees occurring are Grey Box. The groundcover is dominated by introduced species such as
Wild Oats and Bromes, with native Speargrass (Austrostipa scabra) also occurring.
Shrubs are sparse throughout the study area with only two native shrub species recorded,
Western Silver Wattle (Acacia decora) and Cootamundra Wattle (A. baileyana), which is not
locally endemic.
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; St John’s Wort (Hypericum perforatum) and Briar Rose (Rosa rubiginosa) (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.
Vegetation communities
Vegetation communities in the study area are shown in Figure 6.1. Areas of woodland that
contain a canopy dominated by Yellow Box and/or Blakely’s Red Gum, such as along
Mangoplah Road and Cornwall Street (see Figure 6.2), are classified as the threatened
ecological community White Box Yellow Box Blakely’s Red Gum Woodland (Box-Gum
Woodland), which is listed as endangered under the TSC Act and critically endangered under
the EPBC Act if more stringent criteria are met. Due to the degraded groundcover in the patch
along Cornwall Street, it only qualifies for listing under the TSC Act due to the presence of
canopy species. The proposal would be located adjacent to the Box-Gum Woodland along
Cornwall Street.
Areas of woodland that contain a canopy dominated by Grey Box, such as along Scott Street
and Milne Road, are classified as the threatened ecological community Inland Grey Box
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 21
woodland in the Riverina, NSW South Western Slopes, Cobar Peneplain, Nandewar and
Brigalow Belt South bioregions (Grey Box Woodland), which is listed as endangered under the
TSC Act. To qualify for listing under the EPBC Act more stringent criteria must be met. The
proposal would be located adjacent to the Grey Box Woodland along Scott Street, therefore a
determination of the woodland classification was not undertaken.

Fauna
Surveys undertaken by GHD identified 22 fauna species, of which three are introduced, the
Common Starling (Turdus merula), House Sparrow (Passer domesticus) and Feral Pigeon
(Columba livia). These species are listed in 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 the Galah (Eolophus roseicapillus), Sulphur-crested
Cockatoo (Cacatua galerita) and Australian Magpie (Cracticus tibicen). No threatened species
of bird were recorded during current surveys, however, the Grey-crowned Babbler
(Pomatostomus temporalis temporalis) was recorded during surveys for the environmental
planning overview (Environmental Assessments Pty Ltd, 2017). The species is listed as
vulnerable under the TSC Act and was observed foraging in Pine Street, immediately to the
west of the Stage A proposal site.
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 may have been due to high
temperatures. The dams, creek and drainage lines in the study area provide potential habitat for
amphibians.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 24
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
Burkes Creek to the north, on private properties, and within the cemetery boundary in the south-
eastern section of the study area. There is marginal habitat provided by grasslands through the
surrounding heavily grazed paddocks
Remnant vegetation in the study area provides 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 corridors for movement. 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 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.
Threatened biota
Threatened biota observed during surveys
No threatened species were recorded during current field surveys. However, the Grey-crowned
Babbler was recorded during surveys for the environmental planning overview in Pine Street,
adjacent to the proposal site.
Likelihood of threatened biota occurring in the study area
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 (see Appendix C).
6.1.3 Potential impacts
Potential direct impacts
Construction
Vegetation removal
The proposal would remove about 2,500 square metres of mostly introduced groundcover
vegetation (see Figure 6.3). Groundcover would be removed where the trench is excavated for
laying of the pipe and installation of associated infrastructure.
The loss of groundcover vegetation may represent a loss of foraging habitat for some fauna
species; however, the habitat is marginal due to the dominance of introduced groundcover
species and its previous disturbance, with better quality habitat available outside the proposal
site in the study are and locality. The groundcover would also be allowed to regenerate
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 25
following completion of the proposal. No trees would be removed by the proposal. The native
plantings predominantly comprising Lomandra and Atriplex species located along the road
reserve between Emily Street and Park Street would be avoided.
Figure 6.3: Introduced groundcover along the Olympic Highway road reserve, between Emily Street and Park Street
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 such as frogs.
The proposal site does not occur in the vicinity of any creeks or dams, however it would be
located adjacent to and within the table drain along part of its alignment. 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. The
proposal has the potential to further introduce and spread weeds in the study area through the
movement of machinery and light vehicle traffic and disturbance associated with earthworks.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 26
Two noxious weeds were identified within the study area. The proposal has the potential to
spread these weeds 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. the Olympic Highway) and utilities.. 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
No key threatening processes listed under the TSC Act or EPBC Act are relevant to the
proposal due to the removal of vegetation being limited to mostly introduced groundcover
species.
Summary of impact assessment
The literature review, database search and field surveys identified 17 birds, three mammals,
one frog, five plants and two ecological communities listed under the EPBC Act and/or TSC Act
known or likely to occur in the study area. The proposal is considered to have a low potential to
impact on threatened biota likely to occur due to the limited vegetation removal required.
Therefore, no assessments of the significance of impacts were required to be prepared.
The proposal is unlikely to impact on any threatened ecological communities or threatened
species due to the minor nature of impacts of the proposal, its location in a previously disturbed
environment, the retention of all trees, and the presence of additional, higher quality habitat
outside of the proposal site.

6.2 Soils, water quality, hydrology and groundwater
6.2.1 Existing environment
Topography and geology
The study area is located in the Brokong 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. Elevation is about 236 metres
above sea level.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 28
Soils
Soil types
The Brokong Plains Mitchell Landscape contains red-brown texture-contrast soils (Mitchell
2002).
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 (see Appendix D).
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.
Flooding
Flooding within The Rock is caused from both Burkes Creek and overland flooding from
Flowerpot Hill, which is located to the south of the town. Numerous flood events have occurred
at The Rock with records extending as far back 1891, with significant recent flooding in October
2010 and March 2012.
Hydrology and water quality
Hydrology
The township of The Rock is located on the floodplain of Burkes Creek, which is a tributary of
Bullenbong Creek, with its confluence about 25 kilometres north-west of The Rock. Burkes
Creek has a catchment area of about 630 square kilometres at The Rock and travels from east
to west through the town. The catchment extends about 45 kilometres to the south-east and
includes the towns of Mangoplah, Pulletop, Burrandana and Westby.
Surface water quality
In the Lockhart Shire there are six creeks that are classified as protected streams, including
Burkes 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. Burkes Creek
also receives licensed discharge from The Rock 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.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 29
Groundwater
There are no registered groundwater bores located in the study area of the proposal. The
nearest groundwater bore with recorded depth to watertable is about nine kilometres south-west
of the study area. The recorded groundwater level is 51.8 metres.
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 Burkes Creek, however, the proposal is not located near the creek and due to the
nature of the works it is unlikely the watertable would be intercepted during construction.
6.2.2 Potential impacts
Topography and soils
Vegetation removal
About 2,500 square metres of mostly introduced groundcover vegetation would be removed as
part of the proposal. Vegetation removal and earthworks would expose soils to weathering
processes, increasing the risk of erosion and sedimentation. Disturbed areas along the proposal
site would be stabilised after construction completion.
Earthworks
The proposal would involve earthworks over the length of the pipeline alignment for excavation
of the trench, as well as for installation of associated infrastructure such as boundary kits.
Earthworks would potentially affect soils, however is unlikely to affect topography due to the
minor nature of the works.
Where the trench is excavated, the topsoil layer and a proportion of the surficial geology would
be removed, exposing the underlying geologic layers. Loose soil, stored beside the trench to be
used as backfill, 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.
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 be store beside the trench to be used as backfill after the pipe is laid.
Loose soil material could erode in periods of high rainfall or windy conditions. This risk would be
managed by backfilling the trench immediately after the pipe is laid in each section, minimising
the storage of soil required.
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.
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:
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 30
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, particularly when construction occurs adjacent to table drains.
6.2.3 Safeguards and mitigation measures
Impact Safeguard Responsibility
and timing
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)
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.

6.3 Landuse and property
6.3.1 Existing environment
Land uses in the study area consist of (see Figure 1.1):
Rural holdings used for agriculture including grazing and cropping
Residences surrounding the proposal site
Crown Land in the north-western section of the study area
The Rock Station and Yard heritage item in the northern section of the study area
The Rock town centre north and east of the proposal site
Existing roads, including the Olympic Highway, Mangoplah Road, Scott Street, Emily
Street, Park Street, Hill Street, Cornwall Street and Milne Road
Burkes Creek located north of the study area
The Main Southern Railway in the northern section of the study area
The Country Regional Network rail line managed by John Holland in the north-western
section of the study area
The proposal site is predominantly located within Council owned road reserve. The proposal
would also be located in the Olympic Highway road reserve, managed by Roads and Maritime,
land operated by the ARTC, and Crown Land leased by Council in the west and northern
sections of the study area.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 32
6.3.2 Potential impacts
Property acquisition
The construction of the proposal would not require a formal easement along the alignment,
therefore no property acquisition is required. Concurrence from Local Land Services, who
manage the Crown Land in the north-western section of the study area, has been given for
construction of the proposal. Roads and Maritime and the ARTC has also given verbal
permission for the proposal to be constructed on their respective lands. Ongoing formal
consultation will continue to occur with Roads and Maritime and ARTC to gain the relevant
approvals prior to construction commencing.
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, 6.4.4
and 6.5.3. The proposal is unlikely to cause significant long-term indirect impacts to land use.

6.4 Noise and vibration
6.4.1 Methodology
The Interim Construction Noise Guideline (DECC 2009) states that construction works with a
duration of more than three weeks should be subject to a quantitative assessment of noise
impacts. It is anticipated that the construction period for the pressure sewerage system will be
about six months; however, the proposal would be constructed progressively along the
alignment, with construction in each area expected to occur over a period less than three
weeks.
Due to the equipment, methodology and timing, these works are only likely to generate low
levels of noise. Therefore, a qualitative assessment of the potential noise impacts of the
proposal has been undertaken.
6.4.2 Existing environment
The study area is located on the southern side of The Rock township and surrounded by
farmland. The topography of the study area is generally flat to gently undulating.
Sensitive receivers with the potential to be affected by noise impacts during construction of the
proposal include residents near the proposal site. Numerous residences are located directly
adjacent to the proposal site, with the pipeline to be generally located within the nature strip of
each property (see Figure 1.1). Existing noise levels in the study area would primarily be
influenced by passing traffic on the Olympic Highway and other local roads, trains on the Main
Southern Railway, and by other noise associated with rural town environments.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 33
6.4.3 Potential impacts
A qualitative noise assessment of potential noise sources adapted from the Interim Construction
Noise Guideline (DECC 2009) is provided in Table 6.2.
Table 6.2: Qualitative noise assessment
Noise Source Questions relating to noise heard at residences Is examination of work practices necessary?
Is noise loud in absolute terms, or relative to other noises in the area?
Does the noise include tones or impulses?
Does the noise occur at times that interfere with sleep or comfort?
Tip trucks Yes Yes, reversing alarms
No Yes
Light vehicles No Yes, reversing alarms
No No
Excavators Yes Yes, reversing alarms
No Yes
Directional drilling machine
No Yes, drilling noise No Yes
It is anticipated that the proposal would typically be completed within the following hours:
Monday to Friday: 7am to 6pm.
Saturday: 8am to 1pm.
Sunday and Public Holidays: no work.
Generally, noise impacts during construction would be intermittent and short-term. With the
implementation of the appropriate safeguards as detailed below, and considering the standard
working hours to be employed, the proposal would be unlikely to have a significant noise impact
on sensitive receivers.
6.4.4 Safeguards and management measures
Impact Safeguard Responsibility
and timing
Construction noise and vibration impacts
A noise and vibration management plan will be
prepared as a section of the construction
environmental management plan. The plan will include
proposed environmental control measures for all high

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.

– location of nearest sensitive receivers
– construction employee parking areas
– designated loading/ unloading areas and

– 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 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
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

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.
6.5 Air quality
6.5.1 Existing environment
Air quality
The proposal site is located in an urban, semi-rural setting, predominantly on the southern side
of the Olympic Highway, adjacent to residential properties and 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 Rock catchment (postcode 2655).
The most commonly reported atmospheric emissions in the catchment are:
Total nitrogen
Total phosphorus.
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. Numerous residences are located along
the length of the proposal site, predominantly along Emily Street and Scott Street (see Figure
1.1).
6.5.2 Potential impacts
Construction
During construction the following activities would potentially result in air quality impacts:
Clearing of groundcover vegetation
Earthworks
Storing spoil for backfill
Transport and handling of soils and materials
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 36
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 short term air quality impacts at residences.
Dust could be generated by construction vehicles travelling along parts of the unsealed
proposal site alignment, including the lane between Emily Street and Scott Street, and the
Crown Land. The impacts of dust generation would be short-term, during the construction phase
only and would be controlled using the safeguards detailed in section 6.5.3.
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.

6.6 Landscape and visual
6.6.1 Existing environment
The landscape character of the study area is generally defined by urban development and rural
properties used for agriculture. The study area is generally flat to gently undulating.
There is remnant native woodland vegetation located adjacent to the proposal site in the road
reserves of the Olympic Highway, Mangoplah Road, Milne Road, Scott Street and Cornwall
Street. Patches of remnant woodland also occur in the southern and western sections of the
study area on private properties, and east of the Crown Land. Native woodland in the study
area provides aesthetic visual character.
Key receivers in the study area include residences along the proposed alignment of the
pressure sewerage system. The proposal site would also be visible from the following roads
(see Figure 1.1):
Olympic Highway
Mangoplah Road
Milne Road
Scott Street
Cornwall Street
Emily Street
Hill Street
Park Street
Carson Road
Nicholas Street
Pine Street.
6.6.2 Potential impacts
Construction
Visual impacts during construction would generally be associated with:
Plant and equipment
Earthworks
Temporary storage of pipe along the alignment.
These have the potential to temporarily affect views for residents and local road users.
Residents and road users would be affected by views of the construction of the proposal,
including earthworks, construction plant and equipment and the temporary storage of pipe along
the alignment as it is being progressively laid.
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 is unlikely to greatly impact upon visual amenity for residents along
the alignment. The proposed air valves located at various points along the alignment would be
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 38
visible for residents during operation; however these are small in size and unlikely to intrude on
the amenity of the area. The barometric loop to be located in the Crown Land would be located
at least 100 metres from the nearest sensitive receiver and therefore unlikely to obstruct any
views in the study area.
It is unlikely that the proposal would cause any substantial obstruction of existing views due to
the small scale of the infrastructure to be installed and the majority of the proposal being located
underground.

6.7 Aboriginal Heritage
6.7.1 Methodology
In assessing the potential impact of the proposal on Aboriginal heritage, the Due Diligence
Code of Practice for the Protection of Aboriginal Objects in New South Wales (DECCW 2010)
was followed.
The proposal is not defined as a low impact activity under the National Parks and Wildlife
Regulation 2009 (NPW Regulation) as it involves excavation of soil. The due diligence process
is therefore relevant to the proposal.
A search of the NSW Aboriginal Heritage Information Management System (AHIMS) was
undertaken on 27 March 2017 for the proposal.
The study area generally has a high level of disturbance. Surveys were not required; as it is
likely that previous disturbance has removed any existing sites of Aboriginal heritage.
6.7.2 Existing environment
The results of the AHIMS search indicate that no Aboriginal objects or Aboriginal places have
been recorded in or near the proposal site, and no Aboriginal places have been declared in or
near the site (see Appendix D).
The study area is located within the Murray-Darling Basin. Aboriginal people have occupied this
part of Australia for up to 50,000 years, with early occupation focused on the resources of
freshwater lakes and rivers and their floodplains. The Rock is located within the boundary of
Wiradjuri Country. Burkes Creek, which runs along the northern boundary of the town, may
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 39
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 study area and proposal site have been substantially modified by agricultural activities and
the development of roads. The proposed pressure sewerage system is located in areas that
have been cleared of native vegetation. No trees that could potentially bare Aboriginal scars
would be removed by the proposal.
6.7.3 Potential impacts
The due diligence assessment process detailed in the Due Diligence Code of Practice for the
Protection of Aboriginal Objects in New South Wales (DECCW 2010) was followed for the
proposal as outlined in Table 6.3.
Table 6.3: Due diligence assessment
Due diligence matter Response
1. Will the activity disturb the ground surface or any culturally modified trees?
Yes – the proposal would disturb the ground surface for the construction of the pressure sewerage system; however the proposal site is located in previously disturbed land. No trees would be removed by the proposal.
2a. Are there any relevant confirmed site records or other associated landscape feature information on AHIMS?
The results of the AHIMS search indicate that no Aboriginal objects or Aboriginal places have been recorded in or near the study area, and no Aboriginal places have been declared in or near the study area.
2a. Are there any other sources of information of which a person is already aware?
There are no other known studies of the area relevant to the proposal.
2b. Are there landscape features that are likely to indicate presence of Aboriginal objects?
No landscape features such as rock shelters, sand dunes, permanent waterways, waterholes or wetlands are present in the study area. The proposal is located on land that has been previously disturbed by clearing and road development. Because the site has previously been disturbed, no further investigation of Aboriginal heritage is necessary.
No Aboriginal sites were identified during the current study, and the study area was assessed
as holding little potential for the existence of undetected Aboriginal sites. It is unlikely that the
proposal would have any impacts on sites of Aboriginal heritage.

6.8 Non-Aboriginal Heritage
6.8.1 Methodology
Heritage databases were searched on 28 March 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
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 41
Heritage Schedule 5 of the Lockhart LEP for zoning and local heritage information.
6.8.2 Existing environment
History of European settlement
The Lockhart Shire was proclaimed in 1906, after Charles Sturt, who was tracing the course of
the Murrumbidgee River, recorded the first European sighting of The Rock and Galore Hill. By
the 1830’s squatters were occupying large areas of land and the era of large stations and
pastoralism began (LSC 2015).
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.
Heritage sites
Three listed heritage items are located in the study area; The Rock Conservation Area, The
Rock Police Station and The Rock Station and Yard. The Rock Station and Yard is listed on the
Lockhart LEP, the state government section 170 register (The Rock Railway Precinct) and on the NSW Heritage Act 1977. The boundary for the site listed on the LEP occurs within the study
area, with the proposal site traversing through its boundary. The western boundary extent for
the site as listed under the Heritage Act 1977 is located further to the east than the LEP
boundary and therefore not within the proposal site (see Figure 1.1).
The Rock Police Station is located about 150 metres north of the proposal site on the corner of
Nicholas Street and Emily Street. The Rock Urban Conservation Area, listed on the Lockhart
LEP is located north of the proposal site. This area is unlikely to be impacted by the proposal.
6.8.3 Potential impacts
It is unlikely that any items of heritage significance would be impacted by the proposal, however
the proposal would involve construction within the gazetted boundary of The Rock Station and
Yard area, as listed under the Lockhart LEP. The proposal is unlikely to impact on any important
features of the heritage listed item and construction within the boundary would be limited to
underboring and trenching within previously disturbed land. No approvals are required for
construction to occur in the LEP listed boundary.

6.9 Traffic access
6.9.1 Existing environment
The proposal site is located in the road reserve of the Olympic Highway and numerous local
roads, including Mangoplah Road, Milne Road, Emily Street, Scott Street and Cornwall Street
(see Figure 1.1). The Olympic Highway is zoned as SP2 – Infrastructure, a state road, and
therefore the responsibility of Roads and Maritime. All other roads along the proposal site are
locally classified roads and the responsibility of Council.
6.9.2 Potential impacts
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 the Olympic Highway and the local roads
in which the proposal would be constructed adjacent to. Construction traffic would travel from
the Council depot in The Rock township north of the proposal site where construction machinery
and site facilities would be located.
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 is about 380 over the six month 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.
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 within road reserves. During the construction
period traffic speed would be reduced and potentially restricted to one lane if required. All roads
would be underbored for installation of the pipe to avoid the closure of roads and disruption to
traffic. The Olympic Highway would remain open for the duration of the construction period.
Consultation with Roads and Maritime has been undertaken to ensure the proposal would be
unlikely to cause any significant disruption to traffic. Construction methods are to be consistent
with Roads and Maritime’s requirements (see section 5.1.2).
Property access
There would be no changes to property accesses during construction and operation. Property
accesses would be underbored in order to avoid disruption to residences. All access would be
maintained throughout construction.

The area surrounding The Rock mainly comprises rural land use. In 2011 the agriculture,
forestry and fishing industry employed 11.2 per cent of all people employed in the Lockhart LGA
(ABS 2011).
Land uses in the study area are listed in section 6.3. Land use in the study area is characterised
by urban development and agricultural land use, including grazing and cropping.
6.10.2 Potential impacts
During construction there would be a potential reduction in amenity for 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 6.3)
Noise and vibration (section 6.4)
Air quality (section 6.5)
Visual (section 6.6).
The construction of the pressure sewerage system includes five metres of pipe and a boundary
kit for connection of each property to the system. While it is not compulsory for residents to
connect to the system, should they wish to do so additional pipe required to connect household
facilities to the system would be at the expense of the resident.
Potential impacts are expected to be minimal (see section 6.3).
Beneficial impacts
The proposal would provide improved sewage management facilities for the affected residents
at The Rock. The new infrastructure would provide a cost effective and efficient sewerage
system

6.11 Waste management
6.11.1 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.
6.11.2 Potential impacts
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. Noxious weed material would be separated from
native green waste
Chemicals and oils
Waste water from wash-down and bunded areas
Excess construction materials
Waste from decommissioned septic/aeration tanks by individual residences
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 proposal is
not expected to generate large amounts of waste, as excavated soil for the trench would be
used as fill once the pipe is laid.
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.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 46
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.

6.12 Climate change
6.12.1 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.
6.12.2 Existing environment
Existing climate
The Rock area receives an average annual rainfall of 565.9 millimetres. Rainfall is spread
evenly throughout the year with a maximum in June (BOM 2017).
The mean maximum temperature for Wagga Wagga, the closest weather station, is 21.8
degrees Celsius. The mean minimum temperature is 9.6 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.
6.12.3 Potential impacts
Potential impacts of climate change on the proposal
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.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 48
There may be impacts to various construction activities from climate change, such as increased
temperatures interfering with the laying of concrete for flushing points etc.
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 proposal infrastructure 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 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 pipeline.
Operation
Maintenance activities would be undertaken 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.

6.13 Demands on resources
6.13.1 Potential impacts
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)
Pipe required to construct the system, including connection to residents and the existing
gravity sewer main
Other materials required for the construction of various components of the proposal
including flushing points, boundary kits, barometric loop 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 6.11.3.

6.14 Cumulative impacts
6.14.1 Existing environment
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.
6.14.2 Potential impacts
The developments outlined in section 6.14.1 above would be likely to have cumulative impacts
in relation to soils and water quality, visual amenity, noise 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 predominantly with road
and agricultural development.
The proposal would be likely to have relatively minor cumulative impacts in relation to these
factors.
6.14.3 Safeguards and management measures
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 6.5
6.15 Summary of adverse effects
The main adverse effects of the proposal would include:
Potential for soil erosion during storage of soil from excavation of the trench, to be used as
fill for the pipeline
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.

7. Environmental management 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
Under Section 138 of the Roads Act 1993 consent would be required for works in the Olympic Highway area. Consent would be required from Roads and Maritime. A Road Occupancy Licence (ROL) is required for any works that have the potential to disrupt traffic flow on any State Road. A temporary Speed Zone Authorisation (SZA) may be applied for as part of the ROL for work requiring a temporary reduction in speed on a state road.
Consent has been granted from Roads and Maritime. A ROL must be obtained prior to work in the vicinity of the highway that would disrupt traffic flow, with a SZA required for a temporary reduction in speed on the highway. Applications for the ROL must be submitted at least ten working days prior to commencement of work.
Consent would be required from ARTC for works within the Main Southern Railway corridor.
Council is in contact ARTC regarding the project. Council are working with ARTC to provide all information required to obtain approval to construction in the Main Southern Railway corridor.
Under section 155 (1) of the Crown Lands Act 1989 consent would be required for works within Crown land. Consent would need to be obtained from the Local Land Services.
Consent has been granted from the Local Land Services for work in the Crown land leased by Council.

8. Conclusion 8.1 Justification
The proposal is required to provide improved sewerage management facilities for affected
residents of The Rock. The proposal would provide residents with an efficient and cost-effective
sewerage service.
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 2,500 square metres of groundcover that is mainly dominated by
introduced species
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. No
trees would be removed by the proposal.
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 2,500 square metres of groundcover most of which is dominated by introduced species. 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 on the local economy.
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.

Object Comment
5(a)(iv) To encourage the provision of land for public purposes.
The proposal would temporarily affect access to some residences during the construction period. These periods of delays are expected to be short in duration with affected residents notified two weeks prior to construction.
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 2,500 square metres of groundcover most of which is dominated by introduced species. 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 proposal
5(b) To promote the sharing of the responsibility for environmental planning between different levels of government in the State.
Not relevant to the proposal
5(c) To provide increased opportunity for public involvement and participation in environmental planning and assessment.
Council has undertaken consultation for the proposal as described in chapter 5. This has included consultation with stakeholders and the community.
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
involved 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.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 64
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 improved
sewerage management facilities.
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 sewerage management
infrastructure.
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 2,500 square metres groundcover which is dominated by introduced
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
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 pressure sewerage system, south of the Olympic Highway at
The Rock, to provide properties with an efficient and cost effective sewerage service. The
proposal includes installation of the pressure sewer mains progressively along the alignment,
with connection of the existing residences to the system and discharging into the existing gravity
sewer system manhole at Cornwall Street.
The proposal is required to establish modern sewerage management infrastructure and improve
facilities for the residents of The Rock.
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 65
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 REF best meets the project objectives but would still result in
impacts relating to biodiversity, soils, land use, noise, air quality and other environmental
factors.
Adverse environmental effects would be minimised through the implementation of safeguards
and mitigation measures outlined in this REF. The proposal would have beneficial impacts by
providing modernised sewerage management infrastructure to the residents of The Rock.
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 REF 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 REF finds that the proposal is unlikely to have a significant environmental impact and
therefore an Environmental Impact Statement is not required.
This REF 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.

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, machinery and temporary stockpiling of materials along the alignment. These impacts would be short-term and would be minimised through the implementation of safeguards detailed in sections 6.4.4, 6.5.3 and 6.6.3.
Short-term minor negative
The proposal would affect the use of the Crown Land in the short-term by trenching through a grazed paddock. Following completion of construction there would be no restrictions on land use.
Short-term minor negative
The construction of the proposal would have visual impacts during the construction period due to the excavation required for the pipe. These impacts would be minor and limited to the construction period.
Short-term minor negative
The proposal would improve waste management systems for multiple residents at The Rock, reducing costs of septic systems for residents and improving waste management infrastructure.
Long-term positive
b. Any transformation of a locality?
The construction of the proposal would have minor short-term visual impacts through the excavation of the site for the pipe. The impacts would be temporary, limited to the construction period and minimised by underboring roads and accesses.
Short-term minor negative
c. Any environmental impact on the ecosystems of the locality?
The proposal would remove about 2,500 square metres of predominantly introduced groundcover. No trees would be removed as part of the proposal. 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.
Short-term minor negative
d. Any reduction of the aesthetic, recreational, scientific or other environmentalquality or value of a locality?
Residences in the study area would potentially be affected during construction by construction impacts as detailed in (a) above.
Short-term minor negative
e. Any effect on a locality, place or building having aesthetic, anthropological,archaeological, architectural, cultural, historical, scientific or social significanceor other special value for present or future generations?
GHD | Report for Lockhart Shire Council – The Rock pressure sewerage system, 2316033 | 72
The proposal is unlikely to impact on any sites or sites with potential heritage or other social values. Safeguards to avoid or minimise impacts on heritage would be implemented as detailed in sections 6.7.4 and 6.8.4.
Nil
f. Any impact on the habitat of protected fauna (within the meaning of the NationalParks and Wildlife Act 1974)?
The proposal wouldn’t remove habitat of protected fauna. Nil.
g. Any endangering of any species of animal, plant or other form of life, whetherliving on land, in water or in the air?
The proposal would not endanger any species of animal, plant or other form of life.
Nil.
h. Any long-term effects on the environment?
The proposal is unlikely to cause any negative long-term effects on the environment due to the retention of all trees and the proposal site being located on previously disturbed land.
Nil
The proposal would improve waste management infrastructure, 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.
Short-term minor negative
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 6.9.3 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.
Short-term minor negative
k. Any reduction in the range of beneficial uses of the environment?
The proposal wouldn’t acquire any private property. Nil.
l. Any pollution of the environment?
Emily Street, Scott Street, Railway Street, Nicholas Street, Milne Road, Mangoplah Road and a short section of the Olympic Highway residences could potentially be affected by construction impacts as described in (a) above.
Short-term minor negative
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.
Short-term minor negative
Waste generated during construction could also pollute the environment. Waste would be managed in accordance with the safeguards outlined in section 6.11.3.
Short-term minor negative
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 6.11.3.
Nil

The railway site is part of an area designated as an urban conservation area in the Town. The railway contributes by forming a strong south-eastern boundary to the area intersecting the town at an oblique angle and crossing the significant main street also at an oblique angle. The station is located just off the axis of the main street and contributes a strong visual element to the form of the town. The station building dates from the period of the towns prosperity and is one of the few remaining unaltered structures from that period.
Note: There are incomplete details for a number of items listed in NSW. The Heritage Division intends to develop or upgrade statements of significance and other information for these items as resources become available.

Statement of significance:
Why is it an Aboriginal Place? Kengal Aboriginal Place is a Dreaming place, a lookout, and a ceremonial site for the Wiradjuri Aboriginal people and descendents.
Why is it important to Aboriginal People? The Rock Hill was traditionally known as 'Yerong', meaning the place of a male initiation site. As such, it was taboo for women and uninitiated males to enter the area, therefore, keeping knowledge of the place a secret. Ossie

Ingram, a Wiradjuri Elder, explains, 'Knowledge about the Rock Hill is not everyday knowledge - it has a spiritual meaning. It is what we are. [It is a] secret knowledgewhich relates to the making of mena place of initiation.' Kengal Aboriginal Place contains the Rock Hill or 'Kengal' (meaning 'sloping hill'), a name given to an early explorer of the region, Charles Sturt, by two Wiradjuri guides from Wantabadgery.
Kengal was created by Baiame (Biamai), the creator in Wiradjuri culture and traditional law. According to local oral histories, Biamai was sent to the Wiradjuri to teach the people how to make fire and spears. Oral histories say that when settlers arrived in the area, they said something which made Biamai (the creator) go away. Baiame left his male and female dingo companions who still today lay in wait for Baiame's return, forming the Rock Hill-Kengal in the physical landscape.
Kengal remained an important place for Aboriginal people throughout the post-1788 era, despite the impacts to the local Wiradjuri people, culture, language and population of a smallpox outbreak inadvertently brought by Eora traders in the 1790s and loss of resources due to colonial settler land claims. Wiradjuri cultural visits to Kengal continued up until the 1950s. In 1962, the area was gazetted as a nature reserve which has since helped to protect the natural values of the area.
Today, the settlements surrounding the Rock Nature Reserve-Kengal Aboriginal Place have seen a drastic increase in Aboriginal populations, which in turn has brought about an increasing appreciation and respect for the site. It continues to be a place which is often visited by local Aboriginal people to maintain and re-establish links to land and culture. Jim Ingram and David Tout explain the importance of Kengal to contemporary Aboriginal people stating, 'The Rock Hill... tells and reminds the Wiradjuri who they are, what to do and why they need to follow the Law. Many of the descendants of Wiradjuri people today forget where they come from. They don't understand what it means to be Wiradjuri.'

Description
Physical description:
What's on the ground? The Yerong Walking Trail starts at the western base of the Rock Hill and winds up to the top of the outcrop. A scar tree used to make a large shield or coolamon can be found within the boundaries of the Nature Reserve while another scar tree and two artefact scatters can be found within adjacent properties. Beyond this area there are recorded campsites, fire hearths, ochre quarries and stone arrangements.
Nature of the environment The Rock Hill or Kengal within the Rock Nature Reserve-Kengal Aboriginal Place is a large eroding outcrop of sedimentary rock and is a prominent physical feature in the Western Plains region of NSW. The area is home to Open Box and Cypress Pine Woodland as well as several plant species including the vulnerable woolly ragwort. Many plant and animal species found at Kengal today were used for traditional Wiradjuri practices and were culturally significant.

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

Dear Michael
Sewerage system at The Rock Review of Environmental Factors
Lockhart Shire Council (Council) proposes to construct a pressure sewerage system at The Rock by connecting properties within the system to a pressure sewer reticulated network. The proposal is
required to upgrade the existing onsite septic (or aerated) systems. The pressure sewerage system has been divided into two stages; Stage A and Stage B. This REF is for the construction of Stage A of the system (see Figure 1).
Stage A of the pressure sewerage system is bounded by Milne Road, Mangoplah Road, Emily Street and the Olympic Highway, and consists of about 45 existing properties plus the Kings Own Hotel-Motel. The existing properties are currently serviced by onsite sewage systems, with the objective of the proposal to
connect these properties to the proposed pressure sewerage system and abandon the existing onsite treatment systems.
The scope of the proposal includes:
Excavation of the pressure sewer system route with open trenches or in some instances with
horizontal direction boring (HDB) methods
Installation of the pressure sewer mains progressively along the alignment
Pipe diameter between 50 millimetres and 75 millimetres
About 5,000 metres in total length of new system
Construction footprint width about two metres either side of the pipeline alignment
Variable pipeline depth, between 500 millimetres to 1,500 millimetre with a minimum trench width of
500 millimetres
Discharge into the existing gravity sewer system manhole at Cornwall Street.
The proposal would cross the Olympic Highway which is zoned SP2 (infrastructure) and is managed by NSW Roads and Maritime Services. It would also cross the Main Southern Railway managed by the
Australian Rail Track Corporation. The crossing would occur in the north-western section of the proposal
2 2316033/Consultation letter_2
site via horizontal direction boring. Council has initiated the consultation process to assist in facilitating
an efficient and mutually beneficial outcome for these sections of the proposal.
Following the railway crossing the pipeline would be located in Crown Land, which is currently leased by Council.
GHD has been engaged by Council to prepare a review of environmental factors (REF) for the proposal, in accordance with of Part 5 of the Environmental Planning and Assessment Act 1979 (EP&A Act) and the NSW State Environmental Planning Policy (Infrastructure) 2007.
We would like to provide you with the opportunity to comment on the proposal to assist in preparation of the REF. It would be appreciated if your organisation could provide comments on issues that you see as needing to be addressed from your companies perspective by Monday 3 April 2017.
We would be pleased to provide further information if required. In this regard, Leigh Maloney or myself may be contacted on (02) 6923 7433 or by email melissa.cotterill@ghd.com and leigh.maloney@ghd.com

Hi Michael As previously discussed PS Solutions has been commissioned by Lockhart Shire Council to undertake the pressure sewerage system design for the Eastern side of The Rock village. The project encompasses a crossing of the Rail corridor with a 200mm PE conduit pipe and 75mm pumped sewer product pipe.
The selected location has been surveyed and detail design undertaken in accordance with ARTC and Australian Standards. Please find attached drawings.
Can you please advise the process required for formal approval of the design and construction of the crossing.
Thank you and regards
Steve

Hi Natalie As discussed please find attached a copy of selected The Rock pressure sewerage system design drawings where the service pipe is proposed to be located within the Olympic Hwy road reserve. The main has been setout being mindful of RMS requirement to locate the pipe as far from the road centreline as possible, however it cannot always be adjacent to the property boundaries due to other services and Table drains etc.
Please advise a convenient time to meet at your offices on Wednesday morning.
Thank you and regards

Hi Melissa
Thanks for your email regarding notification of the upcoming works for the Sewerage Reticulation System at The Rock and impending REF for Stage A.
Could you please advise where the pipe will be located in the Olympic Highway road reserve between Mangoplah Road and Hill Street. RMS’ preference is for the pipe to be located on the road reserve boundary or within private property.
For the purposes of planning for any associated environmental risks, I have attached RMS’ Annexure A which details our conditions and should also be incorporated into Council’s plans and designs.
Please note RMS has minimum depths for utilities in the road reserve, detailed in the annexure, and these are to minimise future conflicts with the asset during RMS maintenance works as well as protecting RMS’ assets. Please also
3
note the RMS requires the pipe to be sleeved where it crosses the Olympic Highway at Hill Street as the pipe will be carrying sewerage under pressure.
If you have any further queries please don’t hesitate to contact myself or RMS Road Maintenance Planner Nicholas Glenn on 02 69236555.
Kind regards
