PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
Executive summary This preliminary environmental assessment (PEA) has been prepared to support a development application (DA) by Elysian WF Pty Ltd (EWF) for the Elysian Wind Farm proposal (Elysian), which meets the threshold for state significant development (SSD) under the State Environmental Planning Policy (State and Regional Development) 2011. The proposed Elysian development would comprise about 32 wind turbines and supporting ancillary infrastructure, with a generating capacity of between 180 MW and 200 MW.
This PEA presents the preliminary wind farm design, and environmental assessment and management information to assist the Department of Planning and Environment (DP&E) in assessing the proposal and the request for Secretary’s Environmental Assessment Requirements (SEARs) that must subsequently be addressed in an environmental impact statement (EIS).
The proposed development site is on the ridgeline in the regions of Kybeyan and Tuross, approximately 22 km north-east of the village of Nimmitabel, NSW. Nimmitabel is a regional township of about 320 residents (ABS, 2016b). The surrounding areas of Kybeyan and Tuross are communities of less than 100 residents (ABS, 2016a).
The site is entirely within the Cooma-Monaro Local Government Area (LGA), is zoned as RU1- Primary Production under the Cooma-Monaro Local Environmental Plan (LEP) 2013 and cover an area of about 1220 ha (12.20 km2), comprising rolling farmland, woodland and forested land. The development site extends about 7 km north/south, and 3 km east/west at the widest point. The topography of the proposal site is variable. North-south elevation ranges from about 1210 m AHD to 1062 m AHD, the highest point located near Tuross Road to the north of the development site. East-west elevation ranges from about 1210 m AHD to 1030 m AHD.
The proposed Elysian development would comprise about 32 wind turbines, with a maximum energy output of between 180 MW and 200 MW. The turbines would have:
• an approximate rotor diameter between 150 m and 170 m • an approximate hub height of between 145 m and 155 m • a planned tip height maximum (ground to tip of vertical blade) of 230 m.
Each turbine would comprise three, up to 85 m blades, which would create a maximum swept area per turbine of about 22,698 m2. The turbines would be connected to each other and to the collection substation via underground transmission lines. The collection substation would be connected to the national grid via:
• the existing 22 kV Essential Energy (EE – asset manager) Nimmitabel-Kybeyan transmission line, which would need to be upgraded to 132 kV to accommodate the additional base load.
• The existing Nimmitabel to Cooma (Polo Flat) 132 kV transmission line, which is currently only strung on one side; therefore, the Project would utilise the un-strung side of this transmission line.
The proposal leverages the strategic advantages of the market and the wind resources present at the Elysian Wind Farm site. The layout of the Elysian Wind Farm will continue to be refined as the environmental and heritage constraints of the site become known and as detailed studies are undertaken to support the EIS.
EWF considered many factors and constraints during site selection, including:
• availability of a suitable wind source • the feasibility of the site accommodating enough wind turbine generators to make the development economically
viable • the available capacity of, and ease of connection to the national grid • suitable access for each wind turbine generator • local land use and proximity to residences • potential interaction with nationally and locally significant areas relating to environment, biodiversity and
Aboriginal and non-Aboriginal heritage.
Optimisation of the turbine layout considered other constraints including radio communication links and cadastral data for adjacent state forest boundaries were addressed. Wind data is also being collected from two meteorological masts installed within the site boundary. Other environmental, geotechnical and logistical constraints may further modify a wind farm layout as the design develops.

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd

As an alternative to proceeding with the proposal, EWF considered investing in renewable energy developments or operational facilities elsewhere. However, the lost opportunity to produce renewable wind energy on this site would be contrary to the current legislative context which is encouraging investment in clean energy generation to combat climate change, and to provide improved energy security.
To inform this PEA, EWF undertook a program of community and stakeholder consultation focussed on: • immediate neighbours (property boundaries) • neighbours within up to 3.1 km of the proposed wind turbines • neighbours along the proposed transmission easement corridor • key State government agencies and local Councils.
Wind energy developments in NSW are subject to various Commonwealth and state legislation, State Environmental Planning Policies (SEPPs), and local Environmental Plans. The PEA has considered legislative context for the proposal.
The identified environmental constraints have informed the turbine layout of the proposed development. Key issues for consideration at the scoping stage of the environmental impact assessment (EIA) are based on the standard SEARs for wind energy projects and include:
• landscape and visual impact • ecological impact • Aboriginal and cultural heritage impact • access and transport of turbines and associated infrastructure and building material to the site • noise and vibration • aviation • telecommunications • health • bushfire • blade throw • water and soil impact • waste management.
Landscape and visual
Of the 34 dwellings identified within the visual magnitude buffer (3100 m):
• 3 (~9%) dwellings would not have visibility of any turbines • 4 (~12%) dwellings would have visibility of one turbine only • 7 (~21%) dwellings would have visibility of up to two turbines • 2 (~6%) dwellings would have visibility of up to three turbines • 18 (~53%) dwellings would see four or more turbines.
Of the 17 dwellings identified between 3100 m and 8000 m from any turbine, three have views of multiple turbines within more than one 60 degree viewshed.
Noise and vibration
The noise interrogation for the proposed Elysian development concluded:
• noise modelling in accordance to the Wind Energy: Noise Assessment Bulletin was undertaken to inform the PEA • all non-stakeholder and stakeholder dwellings are located more than 500 m from any of the proposed turbines,
which accords with the WHO guidelines • the topography of and adjacent to the site in the north-east may provide natural noise attenuation to buffer noise
propagated by the turbines, especially to the receivers along Tuross Road • receivers may experience elevated noise levels during construction of the proposed Elysian development;
however, construction activities are temporary, and over a short-duration, and would be conducted in accordance to the relevant construction noise and vibration guidelines
• noise levels and perceived noise levels may fluctuate in response weather conditions, e.g., high wind speeds would result in faster turbine rotation, which may lead to higher mechanical noise levels

• wind speed and direction may influence affect noise levels at receiver locations • noise generated by wind turbines can often not be discriminated from noise generated by standard rural and
agricultural practices (e.g., machinery operation, farm vehicles, bores and pumps, livestock) • some vibration impacts associated with the construction of the wind farm may occur; however, the proposed
development site is relatively isolated from nearby properties, which assists in the separation of the source of any construction related vibrations from sensitive receivers
• aside from impacts during construction, operation of the proposed development is not anticipated to result in ongoing vibration impacts.
Biodiversity
The findings of the desktop biodiversity assessment determine the following potential impacts from the proposed Elysian development:
• the project will directly and indirectly impact four threatened ecological communities through the direct clearing of vegetation. Vegetation removal that may be required for the proposed works would likely contribute to loss of parts of the TECs affecting habitat and potentially resulting in further fragmentation of communities within the locality
• hollow-bearing trees provide habitat for threatened species such as forest owls, woodland and forest birds and microbats, which may occur within the study area. As such, the proposal has the potential to remove these tree hollows impacting on threatened species that may utilise them as habitat
• construction of turbines and their access roads may clear logs and debris used by threatened fauna such as the Spotted-tailed Quoll (Dasyurus maculatus) and Striped Legless Lizard (Delmar impar)
• the operation of the wind turbines has the potential to directly impact upon threatened birds and bats. Direct impact would take the form of birds and bats being struck by the turbines blades when moving within or through the wind farm
• the wind farm may create a barrier to movement along the forests of Eastern Australia. Species such as the White-throated Needle-tail (Hirundapus caudacutus) will migrate latitudinally across Australia, preferentially moving over forested areas such as Wadbilliga National Park
• the wind farm may create a barrier to movement longitudinally for some threatened bird species. The Flame Robin (Petroica phoenicea) for example, can migrate to the coastal lowlands in the winter
• priority weeds are likely to occur in parts of the study area. Continued weed invasion and encroachment could have potentially severe consequences for the habitat of flora and fauna occurring in the area
• there is also potential for vegetation within the study area to be classified as koala habitat; this includes ‘potential koala habitat’ based on identification of feed tree species in accordance with State Environmental Planning Policy No 44 – Koala Habitat Protection
• potential sediment, nutrient and pollutant run-off into adjacent vegetation and fauna habitat • noise and vibration disturbances to fauna • temporary light disturbance to fauna during the construction stage of the work.
Traffic and transport
The traffic and transport assessment determined that historical and existing development and commercial activities in the region include the Snowy Hydro scheme and commercial logging, which suggests that local road infrastructure would be able to accommodate turbine and other infrastructure deliveries with or only minor modification. For example, the most likely route from Cooma to the proposed Elysian development site requires a left turn from Polo Flat Road onto Numeralla Road. This intersection would likely require modification to accommodate delivery of the proposed development infrastructure.
Alternatively, goods may be transported to Nimmitabel via the existing OSOM route; however, this route would also require a sharp (90-degree) left turn from Monaro Highway onto Bombala Street. Further investigations would be required to confirm if this intersection could accommodate the delivery of the proposed development infrastructure. This intersection has established buildings and roundabout, therefore any required modification to it could be costly.
Health and safety
The health and safety assessment included aviation, telecommunications, health, bushfire, blade throw and blade glint.

During preparation of the EIS further consultation will be required with AirServices Australia and CASA during the preparation of the EIS due to the proximity of the proposed Elysian development to the Canberra to Mallacoota flight path. AirServices Australia and CASA require advance advice about the project, and monthly updates during construction. The CASA would, as necessary refer the project to the Royal Australian Air Force (RAAF) Aeronautical Information Service (AIS) for inclusion of the turbines in the Tall Structures Database for Australia.
Wind farms may cause electromagnetic Interference (EMI) which can reduce signal strength and coverage of mobile phones, radio and aircraft navigation systems. Wind farm development may cause EMI in the following ways:
• near-field effects where the signals within the generator and nacelle cause interference; however, this has been mostly overcome with technological advances in turbine design
• diffraction where a turbine reflects or absorbs a signal • reflection / Scattering where the turbine obstructs the signal and causes interference or distortion (Bacon, 2002).
Exclusion zones (Fresnel zones) would be required around radio communication signals and near-field exclusion zones from radio towers.
Digital TV which has been delivered throughout Australia is not impacted by ghosting associated with wind turbines. There can be some associated reduction to service strength; however, this can be overcome by upgrading dwellings to a directional aerial which is able to disregard refracted signals from turbines. Satellite TV services (pay TV and TV delivered by the VAST service) are not impacted unless the direction of the dish antenna directly aligns with a turbine.
A specialist consultant has been engaged to prepare a report on telecommunications and EMI. This report would be used to inform the EIS.
Repeated exposure to high noise levels may cause stress, annoyance and sleep disturbance. Wind farms generally do not generate high audible noise levels, with measured levels between 30 to 45 dB(A) up to about 1500 m. Wind farms do generate infrasound and low frequency noise however exposure to this type of noise has not been shown to adversely impact health outcomes.
The current NHMRC research concludes that there may be some noise impact on residences within 1500 m of a wind farm which should be further investigated. An Acoustic Consultant will be engaged during the formal EIS process to prepare a detailed noise impact assessment to determine the impact (if any) on sensitive residential receivers within proximity of the proposed development.
An awareness of the risk of fires is important for any development in rural or regional Australia. Fires are a risk to life and property. Given the recent history of bushfires at the proposed Elysian development site, bushfires may be a threat to the project. Access to the wind farm site, and individual turbines would be improved to facilitate adequate response times for fire events should they occur. Identification of bushfire risks, consequences and likelihood of occurrence is addressed in the Snowy Monaro Bush Fire Risk Management Plan (SMBFMC, 2009), which should be referenced during subsequent deign and environmental assessment.
Aboriginal heritage
The requirements of efficient wind farm establishment are such that the locations of proposed turbines often coincide with topographic elements that have higher archaeological potential, likewise access roads often follow crest and/or level topography for ease of construction. The suite of proposed locations examined in this study fits that coincident model in large measure, and as such the majority of proposed turbine locations should be subject to a detailed field inspection prior to development occurring. This inspection should take the form of an Aboriginal Cultural Heritage Assessment, following the requisite guidelines and standards issues by the NSW Office of Heritage and Environment.
Prior to such inspection the proponent should examine the design of the proposed development with reference to more detailed topographic information (for example, LiDAR generated contour maps) in order to determine if any proposed turbine locations and or access tracks are now on, or are able to be moved to, topography with a slope of >70, as this would place any such turbine / compound in zones of lower archaeological sensitivity.
Water
There are several ephemeral creeks and streams that transect the proposed Elysian development site, and several semi-permanent informal dams, along Tuross Road for example. Design of any crossings would need to consider potential blockages and be able to withstand overtopping without scouring across the road surface or downstream embankment.
Creek crossings will need to ensure they have capacity for significant events without creating or exacerbating erosion potential. Culvert designs will need to ensure the downstream apron is as wide and flat as possible with long-term stable

scour protection to reduce concentrated flows and scour velocities. There is also mapped key fish habitat (KFH) within the site which would need to be considered in detail during the EIS.
There are no registered groundwater bores located within the proposed Elysian development site; however, given the history of grazing at the site, it is likely that unregistered groundwater bores occur within the proposal boundary. This would be assessed during the EIS.
Soils
Investigations undertaken to inform this PEA suggest that the potential for site contamination is low; however, it is still suggested the management methods be considered.
Waste
Given the isolated nature of the proposed Elysian development site, appropriate management, storage and disposal of waste during both construction and operation of the wind farm is an important consideration. To minimise waste generation on-site, contractors and employees would be encouraged to efficiently order construction and office waste, reuse and recycle waste where possible and appropriately dispose of waste which is unable to be reused on-site by way of regular commercial collection by licenced contractors.
Waste generated by construction and operation of the proposed development would be minimal and that the site can be appropriately managed to prioritise recycling and reuse of materials where possible and minimise impact on landfill. The proposed development is expected to generate minimal waste during operation. However, waste will be an important consideration once the Elysian development matures and must be decommissioned.
Cumulative impacts
The significant +50 km of separation between the proposed Elysian development and the closest turbine in the Boco Rock wind farm would minimise cumulative visual impact. Boco Rock Wind Farm is not visible, even in good weather, from high points on the proposed Elysian development site. Topography and vegetation between the sites provide interruption of the viewshed.
It is anticipated that the proposed Elysian development would have the following beneficial impacts on the local and regional area:
• contribution to the local economy through creating jobs for contractors during construction and ongoing employment during operation
• demand for secondary services in the local area during construction • securing additional renewable energy sources to meet electricity demand in the wider community.

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
1 Introduction This preliminary environmental assessment (PEA) has been prepared to support a development application (DA) by Elysian WF Pty Ltd (EWF) for the Elysian Wind Farm proposal (Elysian), which meets the threshold for state significant development (SSD) under the State Environmental Planning Policy (State and Regional Development) 2011. The proposed Elysian development would comprise about 32 wind turbines and supporting ancillary infrastructure, with a generating capacity of between 180 MW and 200 MW.
1.1 Purpose of this document This PEA presents the preliminary wind farm design, and environmental assessment and management information to assist the Department of Planning and Environment (DP&E) in assessing the proposal and the request for Secretary’s Environmental Assessment Requirements (SEARs) that must subsequently be addressed in an environmental impact statement (EIS). This PEA provides:
• a description of the proposal including the proposed design • a description of the proposed site and surrounding environs • statutory framework relevant to securing project approvals • a preliminary environmental and social impact assessment • proposed safeguards and management measures to address potential short- and long-term impacts from the
proposal.
Some of the assessments that informed this PEA provide more detail than is typically required at the PEA stage, to more accurately portray the potential impacts associated with the development, with the intent of satisfying some of the required SEARs at an early stage of the development proposal. This more detailed approach also accommodates seasonality requirements of ecological assessments typically imposed by the Office of Environment and Heritage (OEH).
1.2 Proponent details EWF is a wholly-owned subsidiary of Alinta Energy. Alinta Energy is the fourth largest energy retailer in Australia and is targeting to support the development of 1000 MW of renewable energy by 2020. Details of the proponent are provided in Table 1-1

2 Proposal identification 2.1 Location The proposed development site is on the ridgeline in the regions of Kybeyan and Tuross, approximately 22 km north-east of the village of Nimmitabel, NSW. Nimmitabel is a regional township of about 320 residents (ABS, 2016b). The surrounding areas of Kybeyan and Tuross are communities of less than 100 residents (ABS, 2016a).
The site is entirely within the Cooma Monaro Local Government Area (LGA), is zoned as RU1- Primary Production under the Cooma-Monaro Local Environmental Plan (LEP) 2013. Collectively the site covers an area of about 1220 ha (12.20 km2), comprising rolling farmland, woodland and forested land. The development site extends about 7 km north/south, and 3 km east/west at the widest point. The topography of the proposal site is variable. North-south elevation ranges from about 1210 m AHD to 1062 m AHD, the highest point located near Tuross Road to the north of the development site. East-west elevation ranges from about 1210 m AHD to 1030 m AHD. North-south and east-west elevation profiles are shown in Figure 2-1and Figure 2-2. The locations, relative to the proposed wind farm, of these transects are shown in Appendix A.
Figure 2-1. North-south elevation profile
Figure 2-2. East-west elevation profile
Site access may be possible via Tuross Road and several private tracks which intersect the proposal site at various locations. A detailed traffic and transport assessment would be completed to inform the EIS. The indicative turbine layout is provided in Figure 2-4.
2.2 Development overview The proposed Elysian development would comprise about 32 wind turbines, with a generating capacity of between 180 MW and 200 MW. The turbines would have:
• an approximate rotor diameter between 150 m and 170 m • an approximate hub height of between 145 m and 155 m

• a planned tip height maximum (ground to tip of vertical blade) of 230 m.
Each turbine would comprise three, up to 85 m blades, which would create a maximum swept area per turbine of about 22,698 m2. The turbines would be connected to each other and to the collection substation via underground transmission lines. An indicative turbine layout is provided in Figure 2-4.
The collection substation would be connected to the national grid via the existing 22 kV Essential Energy (EE – asset manager) Nimmitabel-Kybeyan transmission line; however, this line would need to be upgraded to 132/22 kV to accommodate the additional base load. This would provide a benefit to local residents by ensuring enhance electricity supply to existing connections, and additional capacity for future connections as required. It is anticipated that the total number of masts associated with the upgraded transmission line would be reduced; however, the masts would be taller and therefore a wider easement would be required. The existing transmission easement is well defined and maintained, free of vegetation and largely follows the alignment of Kybeyan Road. It is anticipated that to accommodate a 132 kV transmission line, a 40 m wide easement would be required; however, this would need to be determined based on subsequent discussions with Essential Energy. At this stage, the approvals for the transmission line upgrades would be considered in the EIS for the project.
The Nimmitabel-Kybeyan transmission line joins to the existing 132 kV Cooma to Steeples Flat transmission line. This transmission line (97R/2) was designed as a dual circuit line (i.e., one circuit each side of the masts); however, currently, only has one circuit installed. EWF have approval in principal from Essential Energy to install a second circuit to accommodate the additional base load from the Elysian development. Due to the existing structure, installation of a second circuit would not require redesign or widening of the existing easement.
The proposed transmission connections are shown in Figure 2-5.

2.3 Major wind farm infrastructure components 2.3.1 Wind turbine (tower and blades)
Wind turbines harness the power of the wind and use it to generate electricity. This is achieved through wind turning the blades around a rotor. The rotor is connected to the main turbine shaft, which rotates a generator to create electricity. The detailed design for the proposed development has yet to be finalised and as such the turbine type has not been decided. However, both the commonly used double fed induction generator (DFIG) and the direct drive turbine would be considered. The main features of the wind turbines include:
• three variable speed blades for main shaft rotor control • upwind design (nacelle rotates into the wind) • power converter on the rotor side of the generator (power exited through slip rings and carbon brushes) for
variable speed grid synchronisation and power quality movements • Nacelle which house the main shaft, gearbox (in DFIG) and generator • blades • hub which connects the blades to the main shaft • tower section which connects the nacelle • in built step-up transformer.
The turbine blades convert kinetic energy from the wind into mechanical energy through the rotor hub and into the main turbine shaft. Blades composed of stronger composite materials allow for increased length, which in turn allows for a greater amount of wind energy to be captured, and ultimately a greater amount of electricity generated per rotation. Such advances in blade materials and technology have led to increased cost-efficiencies for wind energy developments.
The blades essentially lift and rotate when wind is blown over them, causing the rotor to spin. The blades are connected into a motor or hydraulic pitch actuator, which allows the blades to change angles and convert more, or less of the available energy depending on wind speeds. Each blade is equipped with a lightning conductor on the tip end, which channels lightning strikes to an earthing point, thus protecting the internal electrical systems. Figure 2-6 provides a

2.3.2 Nacelle
The nacelle is a housing that encloses the gearbox, generator, transformers, motors, brakes, electronic components, wiring, and hydraulic and lubricating oil systems. It is typically constructed of steel and fibreglass and has weather monitoring equipment located on top, which provides data on wind speed and direction to assist the automatic operation of the wind turbine.
2.3.3 Footings Three types of foundations may be considered for the turbines, pending the results of geotechnical investigation of ground conditions at the site. These may include:
• slab (gravity) foundations, which would involve excavating about 450 m3 of ground material to a depth of about 2 m. About 200 m3 of this material may, if suitable, be reused as fill around the turbine base. A slab foundation would involve installing shuttering and steel reinforcement, prior to pouring concrete
• slab plus rock anchor foundations, which would involve excavating about 300 m3 of ground material to a depth of about 2 m. These foundations also require shuttering and steel reinforcement, plus rock anchor piles to a depth of about 20 m. Concrete is then poured and once cured, the rock anchors are stressed and secured
• single mono-pile foundation (rock anchor), which would involve excavating about 50 m3 of ground material using a rock drill to a depth of about 10 m. About 30 m3 of this material may, if suitable, be reused as fill around the pile. Once excavated, a tubular pile with a tower flange is inserted and concrete poured in situ.
EWF would undertake detailed geotechnical investigations during pre-construction work to determine the appropriate foundation to use for the development. The geotechnical conditions of the proposed development site may warrant the use of several foundation types. Excavation areas provided are a guide only and may change depending on geotechnical conditions encountered on site.
2.3.4 Monitoring masts EWF has installed 2, 110 m meteorological monitoring masts to collect additional wind and meteorological data.
2.3.5 Access roads Where required, roads would be upgraded, widened or constructed to accommodate material transportation and access to each turbine within the project area.
2.3.5.1 External roads
External roads may require upgrades or maintenance to facilitate construction traffic loads and maintenance during operations. A detailed traffic and transport assessment would be undertaken to inform the EIS, and once the Elysian design, infrastructure components, and materials and equipment entry points are better defined. Required approvals would be obtained by EWF prior to commencement of work.
2.3.5.2 Internal roads
Where possible, EWF intends to use existing internal access roads/tracks rather than establishing additional roads. Access roads in general would be 5 m wide, but some portions may be required to be up to 12 m wide during construction to allow an appropriate splay for turbine shaft and blade delivery, and construction vehicle access. The site will require connecting roads between wind turbines and hardstand areas. The site roads network would be rationalised and, where possible traverse ridgelines or plateaus. A gradient criterion would be implemented to ensure safe access for delivery of project infrastructure. The roads would be surfaced with compactable, engineered base material with suitable drainage. Materials would be sourced locally where possible and in consultation with the local councils. Material from excavation will be reused as much as possible for backfilling roads and platforms. Importing material from outside the Site will be minimised.
2.3.6 Utility requirements
2.3.6.1 Electricity
During construction, generators would provide electricity for site activities. Electricity would be used mainly in the local site offices. Generators might also be used during the pre-commissioning phase to start turbine testing prior to the grid being available at the on-site substation. The type of generator to be used was not known at the time of preparation of
Proposal identification

this PEA; however, EWF would aim to select a generator type that minimises emissions and use of petroleum hydrocarbons.
During operation, electricity would be taken from the grid and no additional generators would be required.
2.3.6.2 Water
A hydrological assessment would be undertaken to confirm the availability of a feasible water resource for construction and operation of the project. Further information on water resources near the proposed Elysian site is provided in Section 6.8.
2.3.6.3 Sewerage
EWF would provide potable ablutions for use on-site during construction.
2.3.7 Hardstand Each wind turbine construction area will have a temporary hardstand area of about 45 m2 adjacent to each wind turbine for cranes to use during construction. Clearing of native vegetation to construct access roads and hardstand areas would be avoided where possible. If clearing is unavoidable, EWF would appropriately manage clearing to minimise vegetation disturbance. The hardstand areas will be maintained throughout the operational life of the wind farm and used principally for the periodic maintenance of the wind turbines.
2.3.8 Temporary site compound / laydown area
A temporary construction operations area of about 5 ha would be established during the construction period. Construction machinery and turbine components may be stored in a laydown area. The laydown area would be made by levelling and temporary compaction of top surface and fencing.
2.4 Major electrical infrastructure 2.4.1 Generator transformer The wind turbine generators typically produce electricity at nominally 0.69 kV which is increased to 33 kV by the transformer located either in the nacelle, the base of the tower or close to the base of the tower on a concrete pad. The output from each of the turbines would be directed via 33 kV cables to the 33 kV / 132 kV collector substation.
The generator transformer may be oil-filled or a dry type depending on the final wind turbine design. Where oil-filled transformers are used, appropriate measures will be incorporated to prevent any oil loss reaching local water courses. The oil volume used for generator transformers would be approximately 1000 L.
2.4.2 Collection substation The onsite collection substation will be located on a one-hectare (approx.) platform and would comprise electrical equipment such as:
• 33kV/132kV transformer(s) • surge arrestors • voltage transformers • current transformers • circuit breakers • disconnectors.
The substation will be connected to an existing EE 22 kV transmission line, which will require upgrading to a 132 kV line to accommodate the additional base load. This upgrade would also provide a more reliable electricity supply for the local community.
A control building would be located next to the substation, but within the 1 ha platform described above. The control building would house all the electronic devices, e.g., the supervisory control and data acquisition, and the control and automated systems.
During construction and operation, the substation would be surrounded by a security fence to keep visitors away from electrical devices.

2.4.3 Overhead and underground cables
Underground cables would be installed between turbines and from the turbines to the substation, to connect the turbines to the grid. The cable alignments would follow the road layout as closely as possible to avoid additional environmental disturbance.
Overhead cables would be used to connect the substation to the existing Nimmitabel-Kybeyan transmission line.
2.4.4 Maintenance facility A maintenance facility would be built next to the substation. This building would store spare parts for the turbines and substation and small quantities of diesel fuel in suitably designed storage units. The design of the maintenance facility would be finalised during the design development phase.
2.4.5 Connectivity to the grid The wind farm would be connected to the grid via the existing EE Nimmitabel-Kybeyan 22 kV transmission line, which will be upgrade to a 132/22 kV line to accommodate the additional base load. The Nimmitabel-Kybeyan transmission line enters the proposed development site at the west. The upgrade 132 kV transmission line would then be connected to the Nimmitabel-Cooma transmission line to the substation at Polo Flat. The proposed connection is shows in Figure 2-8.
EWF have commenced the Application to Connect and approval process with EE.
2.4.6 Battery storage The proposed development may include battery storage at the connection point and provide firming capability to the output of the wind profile. The battery storage facility would cover approximately one hectare of land and be located within the development boundary.
2.5 Development phases The proposed development would comprise seven stages:
1. stage 1 - detailed design and contract development 2. stage 2 – pre-construction, comprising activities such as detailed geotechnical investigations, road upgrades
required for access requirements during construction, site preparation (e.g., topsoil stripping) construction of works facility, erection of signage
3. stage 7 – construction works, likely to be about 18-24 months 4. stage 4 – commissioning, including pre-commissioning checks, collector sub-station energising, commissioning of
turbines, turbine pre-testing 5. stage 5 – operational phase, expected to be initially 25 years, with potential thereafter to repower project
infrastructure for a further 25 year operating life 6. stage 6 – servicing and maintenance 7. stage 3 - decommission – once the operational life of the wind farm has expired, the infrastructure may be
recommissioned or decommissioned, and the site rehabilitated to its current land capacity for ongoing agricultural or alternative land use.
These stages would be discussed in further detail in the EIS. The development timeframe is dependent on planning approvals; however, the proponent has indicated a preferred construction commencement date late in 2020.

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
3 Development justification and alternatives considered 3.1 Global and regional agreements on emissions reduction The Paris Agreement, ratified 4 November 2016, was established under the United Nations Framework Convention on Climate Change to reduce emissions of greenhouse gases to minimise impacts from climate change. One of the primary objectives of the agreement was to encourage development which will reduce greenhouse gas emissions and improve climate resilience to halt the projected increase in global temperatures to less than 2 °C above pre-industrial levels.
As a signatory to the agreement, the Australian Government set a target to reduce greenhouse gas emissions by 26-28 per cent below 2005 levels by or before 2030. To achieve this target, the government is encouraging technological innovation and expanding the clean energy sector (Australian Government, 2016a). Investment in the renewable energy sector is promoted by the Renewable Energy (Electricity) Act 2000 and the Large-scale Renewable Energy Target (LRET). The LRET seeks to secure 23.5 per cent or 33,000 GWh of Australia’s electricity generation from renewable sources by 2020 (Australian Government, 2016b).
At the state level, the NSW Renewable Energy Action Plan (NSW Government, 2013) seeks to attract investment in the renewable energy sector to meet the national target of 20 per cent renewable energy generation by 2020. While at a regional scale, The South East and Tablelands Regional Plan 2036 aims to encourage investment in the renewable energy sector and position the region as a hub of renewable energy excellence.
The NSW Government is providing funding for programs that will help households, businesses and communities benefit from clean energy as NSW transitions to a modern and secure energy system. The State government is helping to promote reliable, clean and affordable energy supply through $30 million for regional community energy projects and increase NSW’s energy capacity by prioritising Energy Zones in the Central-West, South West and New England regions of NSW, which will become a driving force to deliver affordable energy into the future (NSW Govt, 2018).
3.2 Energy reform in Australia Nationally, there are currently 83 clean energy projects in construction or due to start construction, which will deliver over $20 billion in investment, 14,678 MW of renewable energy, and create about 13,514 direct jobs. NSW share of this is 23 project, 3485 MW of renewable energy, $4327 million in investment, and 2120 direct jobs (CEC, 2019). Reform in Australia’s energy sector over the past 5 years has been driven largely by the decarbonisation of energy supply, and the decentralisation and changing energy demand (Figure 3-1).
Wind power is currently the cheapest source of large-scale renewable energy (IRENA, 2018). Recent technological advancements in the sector mean that wind turbines are now larger, more efficient and make use of intelligent technologies (CEC, 2018a). In 2017, wind farms produced 33.8 per cent of Australia’s renewable energy, supplied 5.7 per cent of Australia's electricity and, for the first time ever, contribute almost equal the amount of electricity as hydro energy (CEC, 2018a).
The proposal leverages the strategic advantages of the market and the wind resources present at the Elysian Wind Farm site. The layout of the Elysian Wind Farm will continue to be refined as the environmental and heritage constraints of the site become known and as detailed studies are undertaken to support the EIS.

Figure 3-1. Cumulative generation capacity entry and exit 20136-2017 (Deloitte, 2018)
3.3 Site selection EWF considered many factors and constraints during site selection, including:
• availability of a suitable wind source • the feasibility of the site accommodating enough wind turbine generators to make the development economically
viable • the available capacity of, and ease of connection to the national grid • suitable access for each wind turbine generator • local land use and proximity to residences • potential interaction with nationally and locally significant areas relating to environment, biodiversity and
Aboriginal and non-Aboriginal heritage.
These factors are considered at a local, regional and national context to build a comprehensive understanding of the key issues as the project develops. A summary of the outcomes of this constraint’s investigation is provided in Table 3-1 and Table 3-2 respectively.
Table 3-1. Site selection criteria – preferable site conditions
PREFERABLE SITE CONDITION INVESTIGATION OUTCOMES
Optimal wind resources
The NSW Department of Industry (Resources and Energy Division) has collated information from various sources to produce maps of renewable energy across the State (NSW Government, 2016). Based on a review of these maps, the proposed development site is likely to encounter winds of enough speed and constancy, particularly in elevated areas, surrounded by a smooth and gently rolling land, which promote acceleration of wind speed. The rounded, undulating hills within and adjacent to the proposed Elysian development site offer high wind speed-up due to the topography, and the wind resource map
Development justification and alternatives considered

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd

PREFERABLE SITE CONDITION INVESTIGATION OUTCOMES
suggests that the average wind speed around the Elysian development site is 6.3-10.2 ms-1 (NSW Government, 2016).
Suitable land Use of agricultural land located along ridgelines, providing an elevated platform to erect turbines and capture kinetic wind resources and convert to mechanical energy to integrate into the grid via an existing transmission line.
Residents
A critical consideration in site selection was the rural nature of the site and generally low population density of the region. This reduces the potential for impact disturbance particularly in relation to noise and visual impacts.
The Elysian development would introduce an additional source of revenue and industry to the area, improving regional resilience to bushfires, drought and periods of downturn in agricultural demand.
Capacity to rehabilitate The proposed development works are in keeping with the RU1 - Rural Land zoning. Following decommissioning, it is anticipated that the Elysian site would be used for agricultural purposes.
Proximity to electrical network An existing EE transmission line enters the proposed development site in the west. Connection to this would involve the installation of overhead powerlines and an associated easement.
Connection capacity
EWF have commenced consultation with EE (the asset manager) regarding the proposed connection of the Elysian proposal. At the time of finalising this PEA, EE had confirmed there is capacity available for connection. The consultation process and subsequent verification is ongoing.
Regional skills
Where possible, the development of the Elysian proposal would use existing labour resources from the Cooma Monaro region. Technicians and trade workers make up 14 per cent of the regional workforce, with a further 12 per cent identified as labourers (ABS, 2016a). These resources would also be used, where possible, during operations, servicing and maintenance.
Table 3-2. Site selection criteria – constraints
AREAS OF CONSTRAINT SITE OBSERVATION
Disturbed terrain
The landscape of the development site is disturbed. The site has a history of logging, bushfires and selective clearing for agricultural purposes. Pockets of native vegetation are likely to be impacted by the works; however, the landscape is robust with a demonstrated history of reliance and a capacity for renewal.
Potential residences
There are several dwellings within and adjacent to the proposed development area. These dwellings are comprised of rural residential homesteads, and storage and maintenance facilities associated with agriculture and grazing practices.
Waterways
The site has access to surface water at several locations.
There are mapped key fish habitat within the site, in the north near proposed turbines T7 and T9, and west near proposed turbines T16, T25, T26 and T28. Based on the design at completion of the PEA, none of proposed turbine locations are within 10 m of key fish habitat.

AREAS OF CONSTRAINT SITE OBSERVATION
Aboriginal/non-Aboriginal heritage significance
Initial AHIMS searches (28 March 2019) indicate at least one record of Aboriginal heritage within 1 km of the proposed development site. Several heritage databases were interrogated to assess non-Aboriginal heritage values of the site. These included the State Heritage Register, S170, the Commonwealth Heritage List and the Cooma-Monaro LEP.
Residential zones There is no residential zoning within or adjacent to the proposal development site; however, there are several residential properties in proximity to the site. These properties include associated properties and host properties.
Conservation
This selection of the proposed development site considered environmental and social constraints, which have been further investigated in this PEA to optimise the proposed turbine layout. Environmental and social considerations are discussed in detail in Section 6.
3.4 Preliminary turbine layout The turbine layout is an important consideration in the planning of the site. If wind turbine generators are positioned too close together, they can adversely impact efficiency in energy production and mechanical loads. As such, optimizing wind turbine generator spacing is important so that turbulence and wake interference is minimised. Optimisation of the turbine layout considered other constraints including radio communication links and cadastral data for adjacent land areas. Wind data is also being collected from two meteorological masts installed within the site boundary. Other environmental, geotechnical and logistical constraints may further modify a wind farm layout as the design develops. Preliminary wind data from the site is provided in Table 3-3.
Table 3-3. Preliminary site wind data
VARIABLE DETAILS
Annual mean wind speed [m/s] 8.0
Weibull A 9.1
Weibull k 2.0
Annual mean temperature (°C) 10.6
Annual mean air density (kg/m3) 1.08
3.5 Alternatives considered As an alternative to proceeding with the proposal, EWF considered investing in renewable energy developments or operational facilities elsewhere. However, the lost opportunity to produce renewable wind energy on this site would be contrary to the current legislative context which is encouraging investment in clean energy generation to combat climate change, and to provide improved energy security.
Additionally, the suitability of the site to accommodate a feasible wind energy development, has been determined, and it is likely that if EWF did not invest in this opportunity, others would.
Specifically, the following conclusions justified the decision to proceed with the design development and approvals for the project:
• wind profile consistent to support a feasible wind energy development • proximity to transmission lines to facilitate connection to the grid • separation from residential properties and low regional population density • available water resources • existing access via Kybeyan Road to facilitate delivery of turbine components and construction materials

• favourable topography.
Based on an anticipated generating capacity of between 180 and 200 MW, the local, regional and global benefits outlined in Table 3-4 can be expected.
Table 3-4. Benefit summary
BENEFIT ELYSIAN ENERGY FORECAST
Energy production The project would generate 600 GWh of renewable energy annually. This would support the initiatives developed to reach Australia’s renewable energy targets.
Carbon reduction
Australia’s energy sector is transforming to sustainably meet the electricity needs and objectives of the future. The decarbonisation of the energy sector will only be successful through the concurrent investment in renewable energy generation projects. The Elysian development proposal would provide a sustainable, renewable energy source direct to the national grid, and aligns with the principles of the Clean Energy Council and other industry bodies and guidelines.
Local jobs
Between 50 and 250 direct jobs would be generated throughout the 18-24 month construction phase of the Elysian development proposal. Ongoing employment opportunities would also arise from operation, servicing and maintenance requirements for of the project.
Economic injection The Nimmitabel region would experience economic benefit from increased local spending during construction and operation of the Elysian development proposal.
Consultation

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
4 Consultation The NSW Government’s Wind Energy Guideline (the Guideline) provides the community, industry and regulators with guidance on the planning framework for the assessment of large-scale wind energy development proposals that are SSDs (DPE, December 2016). Consultation with communities and other stakeholders forms an integral part of the assessment process for SSD wind energy projects, and would be a core focus of activity, alongside detailed environmental assessment, supporting development of the Elysian development proposal.
4.1 Consultation To inform this PEA, EWF undertook a program of community and stakeholder consultation focussed on: • immediate neighbours (property boundaries) • neighbours within up to 3.1 km of the proposed wind turbines • neighbours along the proposed transmission easement corridor • key State government agencies and local Councils.
4.1.1 Communication and stakeholder engagement program EWF completed community and stakeholder communications and engagement that meets current best practice guidelines, as identified by DP&E and recent successful wind development benchmarks set in NSW. The subsequent preparation of a Community and Stakeholder Engagement Plan (CSEP) and engagement activities throughout the EIS will be guided by these initial consultations, desktop research, and the SEARs. The following benchmark criteria would shape EWF continued approach:
1. early and ongoing engagement that places an emphasis on face-to-face consultation 2. on-going access to complete and clear information about the proposal and its potential impacts and benefits 3. respectful listening and understanding, including potential for landowner and community benefit sharing 4. proactive and collaborative involvement of the community and key stakeholders throughout the design
development process.
Early consultations, including engagement with DP&E and Snowy Monaro Council will be used to guide the development of the CSEP. The community and other stakeholders have been, and will continue to be, proactively informed of progress of the development at each milestone by use of communications tools such as an innovative interactive website, workshops and face-to-face meetings, printed materials, drop-in style information sessions and other events.
The CSEP would include:
• a description of the project and locality • the SEARs and project timeline • the purpose of stakeholder communication and consultation • the communication and engagement approval process • the approach to communication and consultation • mapping of stakeholder issues and interests • communication and consultation methodology • specification of communication and consultation tools and techniques • preliminary communications messaging • schedule of communication and consultation resources, activities and events. • schedule of target milestones and reporting outcomes.
Consultation would meet best practice guidelines, including the Wind Energy Guideline for State significant wind energy development (DPE, 2016c) and would be delivered across three phases of project development, as follows:
1. Phase 1, scoping consultations (underway) which has been used to inform this PEA and the preliminary design and development of the CSEP, including the SEARs and the detailed preparation of the Community and Stakeholder Engagement Plan (CSEP).
Consultation

2. Phase 2, pre-EIS consultation will not commence before completion, approval and resourcing of the CSEP, including the tools and activities specified to adequately inform and enable preparation of the EIS and the meeting of critical project milestones.
3. Phase 3, EIS public exhibition represents the third and final stage of pre-approval consultations. Phase 3 will commence with preparation of the Elysian Wind Farm draft EIS and proposed design for public exhibition. Phase 3 consultation will enable the key features, benefits, impacts and mitigations of the proposal, informed by Phases 1 and 2 of consultation, to seamlessly coalesce into a shared understanding of Elysian Wind Farm.
4.1.2 Purpose of the PEA consultations The purpose of the stakeholder communication and consultation process is to:
• identify potential impacts to drive better siting and design • provide meaningful, respectful and effective engagement across the development process • encourage benefit sharing with the community • provide greater accountability for the management of impacts over the life of the project.
4.2 Consultation activities undertaken to date The identification of neighbouring properties and dwellings for the Elysian Wind Farm was undertaken through:
• discussion with participating landholders and neighbours • desktop mapping and Geographic Information Systems (GIS) • driving of local roads.
Twenty three neighbouring (i.e., non-stakeholder) dwellings were identified within 3000 m from any of the proposed wind turbine locations. EWF has sought to identify these landholders in order to make contact and commence communication.
Identification of neighbouring landholders was undertaken through:
• discussion with participating landholders and known neighbours • identification of addresses from mailboxes • white pages telephone searches • telephone contact • other local contacts.
Additional consultation was undertaken with residences outside of the 3000 m buffer from any wind turbine. EWF has commenced a database of these stakeholders and a log of communication activities has been recorded (Appendix B).
To date, much of the stakeholder communication methodology has involved telephone calls, email, face-to-face meetings and the mailing of the first project brochure to the immediate and local properties.
EWF has contacted key state agencies and local government stakeholders, including:
• NSW Dept of Planning, Industry and Environment • National Parks and Wildlife • Snowy Monaro Regional Council.
4.2.1 Telephone
Contacting local landholders by telephone has been successful to date. Of critical importance is the fact that many landholders are often only contactable after hours due to reception issues and on-farm commitments. Landholders often discuss their preferred contact method and timing at the first contact. Many landholders do not have mobile telephones, although this is gradually changing.
The project may improve the local area mobile reception for the benefit of the local community through the provision of fibre optic communications lines to the site, with the potential to erect aerials for mobile communication and data.

4.2.2 Email
Email contact of many stakeholders has proven successful for state agency and local government representatives. Email is an effective method of communicating with stakeholders on project progress.
4.2.3 Face-to-Face This is the most effective, but most time-consuming method of communication and engagement with stakeholders and community. Most of the face-to-face meetings held to date have been one-to-one, so deep and effective engagement can occur with strong understanding achieved between the parties.
At the time of lodging this PEA, Willy Willy had engaged face-to-face with the following organisations:
• Lions Club, Nimmitabel • Nimmitabel Post Office • Bellz Café, Bombala Street, Cooma • Nimmitabel Advancement Group • Nimmitabel Common • Nimmitabel Chamber of Commerce • Country Women Association • Nimmitabel Men’s Shed • Federal Hotel Nimmitabel • Nimmitabel Country Club.
These organisations were provided with flyers detailing the proposed development.
EWF hosted representatives of NSW Department of Planning, Industry and Environment, NSW Environment Protection Authority, and Snowy-Monaro Regional Council at an information session in Nimmitabel (at the Royal Arms Hotel on 30 October, 2019). EWF provided an overview of the project, including activities undertaken to date, and then showed the representatives around the proposed development site. Following the site visit, the group reconvened at the Royal Arms Hotel to de-brief and for EWF to field further specific queries.
Lately, EWF have engaged directly with up to 13 neighbouring landowners to discuss the use of their land to install temporary noise monitoring equipment and provide a general update on the project. EWF have also distributed project flyers through Cooma-Monaro Shire Council to all rate payers in the catchment area to capture non-resident land owners in the local area, and distributed posters at strategic locations in Nimmitabel.
4.2.4 Direct Mail The EWF team has utilized a preliminary information brochure to inform the local community of the project proposal. This brochure was hand-mailed to over 80 mailboxes in the local area during April 2019. Using a feedback telephone number and email, members of the community previously unknown to the team have been revealed, improving the effectiveness of the engagement process. It is expected that this technique will be utilized again due to the ease of access to property mailboxes along the local road network.
4.2.5 Communications and Engagement Log A stakeholder communications and engagement log has been developed to record contact details, records of meetings and communications, as well as information on the meeting purpose and content. Actions for next steps for each meeting are also proposed. EWF are interested to adopt a new Customer Relationship Management (CRM) system to better record meeting information and content. Investigations into the optimum system for the project are underway.
A summary of the consultation undertaken is provided in Appendix B. Addresses have been excluded for privacy.
4.3 Stakeholder issues and interests As discussed, the NSW Government supports the development of a sustainable wind energy industry. NSW is naturally endowed with valuable wind resources, by international standards, with many of the best areas located near existing electricity transmission infrastructure. Wind developments generate dependable clean energy, while stimulating regional economic activity, jobs growth and improved social and environmental outcomes. (DPE, 2016c).

KEY ISSUES RAISED
• How does the greater community benefit?
4.5 Next steps EWF will continue to adopt the fundamental methodologies of telephone, email, face-to-face and print mailer. The preference for the methodology, will be driven by individual stakeholders. In addition to these methods, it is proposed to develop further tools in increase and encourage local engagement and participation. These tools will include:
• website with project details and updates • hotline (free call number) • brochure of Frequently Asked Questions (FAQs) • email updates • public displays.
4.5.1 Project Website It is envisaged that the project website would comprise the following
• project background − why Kybeyan? − why wind? − what are the drivers of this project?
• project summary • project specifications
− turbine layout − capacity − emissions reduction summary
• frequently asked questions • project schedule • contact details for more information • how to support the project • request for more information [email protected].
The project website is presently under construction and expected to be installed during Quarter 3, 2019.
4.5.2 Project Hotline This avenue will be more important as the project develops more closely to construction, however it will be possible to link the hotline to the existing EWF phones for urgent community enquiries. The project hotline is expected to be installed Quarter 3, 2019.
4.5.3 Brochures and Tech Sheets It is expected that several brochures and technical sheets will be developed and released as more information is developed and the project progresses. A revised project brochure will be prepared and released when more information is confirmed in relation to expected generation and local grid capacity. A frequently asked questions brochure will also be prepared to reflect the website information and the information collected during the community engagement process.
4.5.4 Public Displays and Exhibitions EWF will conduct a minimum of 2 days of public displays and exhibitions in both the local community and potentially in the regional centre of Cooma. It is expected that the public displays will be able to show the critical elements of the wind farm impacts including:
• final project layout including turbine locations, grid connection route and access roads • visual amenity, including:

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
5 Planning instruments and context 5.1 Context for wind energy development Wind energy developments in NSW are subject to various Commonwealth and state legislation, State Environmental Planning Policies (SEPPs), and local Environmental Plans. The following section details of the legislative context for the proposal.
5.2 Commonwealth legislation 5.2.1 Environmental Protection and Biodiversity Conservation Act 1999
The Environment Protection and Biodiversity Conservation Act 1999 (the EPBC Act) is the Australian Government’s central environmental legislation. It provides a legal framework to protect and manage nationally and internationally important flora, fauna, ecological communities and heritage places — defined in the EPBC Act as matters of national environmental significance.
Under the EPBC Act, a referral to the Australian Government is required for proposed actions that have the potential to significantly and adversely impact on matters of national environmental significance (MNES) or on Commonwealth land.
The EPBC Act streamlines the national environmental assessment and approvals process and promotes ecologically sustainable development through the conservation and sustainable utilisation of natural resources.
Section 6.4 (Biodiversity) provides a discussion of relevant matters protected under the EPBC Act.
5.2.2 Aboriginal and Torres Strait Islander Heritage Protection Act 1984 The Aboriginal and Torres Strait Islander Heritage Protection Act 1984 (ATSIHP Act) assists in the preservation and protection of places, areas and objects of significance to Aboriginal Australians. The ATSIHP Act only applies to areas and objects of indigenous heritage that are of national or international significance or that are located on land owned or managed by the Commonwealth.
Unlike similar NSW legislation, the ATSIHP Act is not designed to protect areas and objects of scientific and historical interest. Instead, the ATSIHP Act can be used by the Minister in certain circumstances to override NSW planning approvals and prevent an activity from occurring by making a declaration to protect an area or object. Section [x] of this PEA summarises the heritage assessment undertaken.
Section 6.7.1 (Aboriginal Heritage) provides a summary of items relevant to the ATSIHP Act.
5.2.3 Civil Aviation Safety Regulations 1998
The Civil Aviation Safety Regulations 1998 requires notification be provided to the Civil Aviation Safety Authority (CASA) as wind farm infrastructure can present a hazard to low flying aircraft.
Section 6.6.1 describes how the project would comply with the CASA Regulations.
5.3 NSW state legislation 5.3.1 Environmental Planning and Assessment Act 1979
The Environmental Planning and Assessment Act 1979 (EP&A Act) is the principal legislation guiding land use development in NSW, including state significant development (SSD) such as proposed development.
The primary of objective of the Act is to promote the social and economic welfare of the community, and a better environment through the proper management, development and conservation of the State’s natural resources. This includes capturing kinetic wind energy for the purposes of contributing to the state and national electricity grid. The Act also promotes the orderly economic development of land.
The Elysian development meets the threshold for SSD and is required to be assessed under Part 4 of the EP&A Act. In the case of an SSD, the consent authority would be the Independent Planning Commission (if the development is of a kind for which the Commission is declared the consent authority by an environmental planning instrument) or the Minister (if the development is not of that kind) (Division 4.2, Section 4.5 of the EP&A Act).
An application for SSD must grant consideration to the matters within Section 4.15 of the EP&A Act, including the provisions of relevant environmental planning instruments, proposed instruments that have been the subject of public
Planning instruments and context
26
PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
consultation, development control plans, planning agreements and statutory regulations. Additionally, consideration must be granted to the likely impacts of the development, suitability of the site, any submissions received and the public interest.
Clause 4.41 of the EP&A Act clarifies that development consent for SSD includes authorisations under the following statutory provisions, meaning that separate planning approval processes do not apply:
• a permit under section 201, 205 or 219 of the Fisheries Management Act 1994 • an approval under Part 4, or an excavation permit under section 139, of the Heritage Act 1977 • an Aboriginal heritage impact permit under section 90 of the National Parks and Wildlife Act 1974 • a bush fire safety authority under section 100B of the Rural Fires Act 1997 • a water use approval under section 89, a water management work approval under section 90 or an activity
approval (other than an aquifer interference approval) under section 91 of the Water Management Act 2000.
5.3.2 NSW Environmental Planning and Assessment Regulation 2000 The NSW Environmental Planning and Assessment Regulation 2000 (EP&A Regs) identifies the standard requirements for the preparation of an EIS and the factors that are required to be considered when undertaking the impact of an activity on the environment.
EWF are obliged to consider Clause 228 of the EP&A Regs regarding identifying environmental impacts. The factors specified under this clause include matters such as impacts on residential and ecological communities, impacts on the visual quality and property values of the locality, impact on protected fauna and long-term environmental impacts. Additionally, the NSW Wind Energy Guidelines for State Significant Development (2016) outlines matters for consideration in any application of this nature, including:
• strategic context (Section 3) • visual impacts (Section 6.2) • noise impacts (Section 6.3) • biodiversity (Section 6.4) • traffic and transport (Section 6.5) • hazards and risks
− aviation safety (Section 6.6.1) − telecommunications (Section 6.6.2) − health (Section 6.6.3) − bushfire hazard (Section 6.6.4) − blade throw (Section 6.6.5)
• decommissioning • cumulative impacts (Section 6.10).
5.3.3 Protection of the Environment Operations Act 1997 The Protection of the Environment Operations Act 1997 (POEO Act) provides an integrated system for the licensing of polluting activities with the objective of protecting the environment. The Environment Protection Authority (EPA) must be notified when a ‘pollution incident’ occurs that causes or threatens ‘material harm’ to the environment. A Plan of Management for the operation of the Site will provide procedures for notification to the EPA in the event of a pollution incident.
The proposed development is a ‘scheduled activity’ under Schedule 1, 17(1) ‘electricity works (wind farms)’ and therefore requires an Environment Protection License (EPL) to be obtained under Section 48 of the POEO Act. Elysian Wind Farm would need to obtain an EPL from the NSW EPA prior to the commencement of operations.
5.3.4 Biodiversity Conservation Act 2016
The Biodiversity Conservation Act 2016 (BC Act) and its supporting regulations commenced on 25th August 2017. The BC Act repeals the Threatened Species Conservation Act 1995 (TSC Act) along with other natural resource management legislation, while retaining the TSC Act species list. The BC Act sets out the assessment framework for threatened species and ecological communities for Division 5.1 activities (amongst other types of development).
Planning instruments and context
27
PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
The BC Act, together with the Biodiversity Conservation Regulation 2017, outlines the framework for addressing impacts on biodiversity from development and clearing. It establishes a framework to avoid, minimise and offset impacts on biodiversity from development through the Biodiversity Offsets Scheme (BOS).
Part 7.9 of the BC Act requires that the significance of the impact on threatened species, populations and endangered ecological communities listed under the BC Act or Fisheries Management Act 1994 (FM Act), are assessed using a five-part test. Where a significant impact is likely to occur, a Species Impact Statement (SIS) or Biodiversity Assessment Report (BAR) must be prepared in accordance with the Secretary’s requirements.
5.3.5 Rural Fires Act 1997 The Rural Fires Act 1997 (Rural Fires Act) aims to prevent, mitigate and supress bush and other fires whilst protecting people, property and infrastructure from damage whilst having regard to the principles of ecological sustainable development. Under Section 63, public authorities must take all practicable steps to prevent the occurrence and spread of bushfires on or from land vested in or under its control or management.
Consultation is required to be undertaken with the Rural Fire Service (RFS) and local Fire Brigades to determine the features required to minimise the threat of fire to the Site.
Bushfires are a known hazard in the Cooma-Monaro LGA, particularly along the Great Dividing Range. The Elysian development proposal site is largely mapped as Category 1, with a few areas of Category 2. Bushfire risk would be considered in the context of the Rural Fires Act at all levels of the development process, from project design through to decommissioning.
5.3.6 National Parks and Wildlife Act 1974
The National Parks and Wildlife Act 1974 (NPW Act) governs the care, control and management of national parks, nature reserves, Aboriginal areas and historic sites including areas vested with the Environment Minister. The objectives of the Act include the conservation of nature, objects, places or features such as habitats, biological diversity, landforms and places of Aboriginal, social or historical value. These objectives are achieved by applying principles of ecologically sustainable development. The management principles for national parks include promoting public awareness, making provisions for sustainable visitor use and the conservation of biodiversity, ecosystem function, natural landscape and cultural value.
An approval for SSD precludes the requirement to separately apply for an Aboriginal Heritage Impact Permit (AHIP) under Section 90 of the NPW Act; however, we anticipate such matters will be addressed in the relevant referral process during the assessment of the EIS.
The Elysian development proposal site is situated between the Wadbilliga National Park, and the Kybeyan State Conservation Area. No land within the proposed site boundary are designated NSW National Parks and Wildlife Services Estates. As such, the environmental assessment would need to consider the interactions of the wind turbine infrastructure on the amenity and function of the nearby NSW National Parks and Wildlife Services Estates.
5.3.7 Fisheries Management Act 1994 The Fisheries Management Act 1994 (FM Act) is in place to conserve fish stocks, habitats and threatened species, populations and communities, to preserve fishery resources for future generations.
In the exemptions under Section 89J(1)(b) of the EP&A Act, an approval for the proposal as SSD would negate the requirement for permits under Section 201, 205 and 219 of the FM Act. Nonetheless, the construction and operation of the proposed development may affect fish passage or cause adverse impact to threatened fish species and we anticipate a referral to the Department of Primary Industries and Office of Environment and Heritage (OEH) would be required.
5.3.8 Water Management Act 2000 The objectives of the Water Management Act 2000 are to provide for the sustainable and integrated management of the State’s water sources for the benefit of both present and future generations. We note that the provisions of Section 4.41 of the EP&A Act clarify that an approval by the Minister for SSD prevails over the requirement for a water use approval under Section 89, a water management approval under Section 90 and an activity approval under Section 91 of the Water Management Act.

5.3.9 Native Vegetation Act 2003
The Native Vegetation Act 2003 (NV Act) aims to prevent broad scale clearing, protect native vegetation of high conservation value and improve conditions of existing native vegetation.
5.3.10 Contaminated Land Management Act 1977 The Contaminated Land Management Act 1977 (CLM Act) establishes a process for investigating and (where appropriate) remediating land that the EPA considers to be contaminated significantly enough to require regulation under Division 2 of Part 3. Furthermore, under Section 60 a person whose activities have contaminated land or a landowner whose land has been contaminated is required to notify the EPA when they become aware of the contamination.
5.3.11 Roads Act 1993 The Roads Act 1993 (Roads Act) sets out rights of members of the public to pass along public roads, establishes procedures for opening and closing a public road and provides for the classification of roads. It also provides for the declaration of WCC and other public bodies as roads authorities for both classified and unclassified roads and confers certain functions (particularly function of carrying out roadwork).
5.3.12 Soil Conservation Act 1938 The Soil Conservation Act 1938 allows for conservation of soil resources and erosion management. Notices can be issued under Section 15A to control erosion or degradation.
The installation of the turbine infrastructure and roads would require cut and fill of existing soil throughout the site. Raw aggregate to make concrete would be imported to the site; however, excavated soil would remain on site for rehabilitation and re-contouring of the site.
5.3.13 Crown Lands Management Act 2016 The Crown Lands Management Act 2016 (Crown Lands Act) provides for the ownership, use and management of Crown Lands. Crown land is land that is vested by the Crown, or was acquired under the Crown Settlement Acts, and is land that is dedicated for a public purpose, such as a cemetery, or land that is sold or lawfully contracted to be sold under consideration of the Crown. The Crown Lands Act ensures that the appropriate environmental, social, cultural heritage and economic aspects be considered when decision-making about Crown lands.
The proposed Elysian Wind Farm site sits adjacent to Crown land, and there are several Crown reserves and Crown tenures within a 10 km radius of the project boundary.
5.4 Environmental Planning Instruments The following Environmental Planning Instruments (EPIs) are relevant to the proposed development according to Section 79C(1)(a)(i), as it applies to the development under Section 89H of the EP&A Act.
5.4.1 State Environmental Planning Policy (State and Regional Development) 2011 Subject to Schedule 1 State significant development – general of SEPP (State and Regional Development) 2011 (SSD SEPP), electricity generating facilities are deemed SSD where they have an output of 30 MW or more and a capital investment value (CIV) of more than $30 million.
The proposed development has a maximum output of 200 MW and a CIV of more than $30 million. As such, the proposal is deemed SSD and is to be referred to the Minister, and if required, the Planning Assessment Commission (PAC) for consideration.
5.4.2 State Environmental Planning Policy (Infrastructure) 2007
The provisions of SEPP (Infrastructure) 2007 (ISEPP) are relevant to the proposal in providing widened zoning permissibility for the delivery of certain infrastructure. In this instance, Clause 34(1) provides prescribed zones within which a wind farm is permissible with consent.
An electricity generating facility is not defined within the ISEPP, so the relevant definition is within the Standard Instrument – Principal Local Environmental Plan as follows:
Planning instruments and context
29
PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
““electricity generating works means a building or place used for the purpose of making or generating electricity”.
The Elysian development site is zoned as RU1- Primary Production under the Cooma-Monaro LEP 2013. The proposed development is contained within the RU1 zone, the assessment buffer area captures E1 zoned land.
In relation to Clause 34(1) of the ISEPP, the RU1 zones are defined as ‘prescribed rural zones’, permitting the proposed electricity generating facility (wind farm) on the Site as development with consent. The widened permissibility of the ISEPP prevails beyond the relevant LEP controls and is to be relied upon for the proposed development.
5.4.3 State Environmental Planning Policy (Rural Lands) 2008 The purpose of SEPP (Rural Lands) 2008 is to facilitate the orderly and economic use and development of rural lands and to implement measures to reduce land use conflicts. The proposed development meets the rural planning principles of Clause 7 of SEPP (Rural Lands) 2008 as it presents an opportunity to introduce a sustainable economic activity to the site and wider locality.
The Rural Planning Principles also require consistency with applicable regional strategies, including the South East and Tablelands Regional Plan, prepared by the DP&E. The proposal is consistent with this regional plan which aims to grow the regional economy and jobs by encouraging investment in various sectors including renewable energy and indicates that renewable energy is a “priority growth sector” for the region. The proposal is also consistent with the NSW Renewable Energy Action Plan (2013) which seeks to attract investment in renewable energy to meet the national target of 20 per cent energy generation by 2020.
5.4.4 State Environmental Planning Policy No. 55 – Remediation of Land
SEPP No. 55 – Remediation of Land (SEPP 55) requires the consent authority to consider whether the land is contaminated, and if the land is contaminated whether it is suitable in its contaminated state or following remediation works.
5.4.5 Local Environmental Plans
5.4.5.1 Cooma-Monaro Local Environmental Plan 2013
The proposed Elysian development site is wholly located within the Cooma-Monaro LEP area. As discussed, the proposed development is consistent with the objectives of relevant land zoning under this LEP. The objectives of relevance to the proposed development encourage sustainable primary industry production and a diversity in primary industry enterprises, whilst minimising impacts on adjoining land uses. The wind farm will provide a new and sustainable renewable industry which will diversify the types of economic activity offered within the area and will allow the land beneath the turbines to continue to be used for traditional farming purposes, if desired.
The objectives of RU1 zoning include to:
• encourage sustainable primary industry production by maintaining and enhancing the natural resource base. • encourage diversity in primary industry enterprises and systems appropriate for the area. • minimise the fragmentation and alienation of resource lands. • minimise conflict between land uses within this zone and land uses within adjoining zones. • encourage land uses that are unlikely to generate significant additional traffic relative to the capacity and safety
of a road or create or increase a condition of ribbon development on any road. • encourage land uses that are unlikely to create unreasonable or uneconomic demands for the provision or
extension of public amenities or services. • protect the water quality of receiving watercourses and groundwater systems. • protect the visual landscape values of the rural area.
The proposed development is not prohibited in the RU-1 land use zone and are permitted with consent, indicating that the proposal would be compatible with this land zoning. During the construction stage of the works, clearing and excavation would be required for turbine footing, hardstand areas access tracks, substations and control buildings. These activities would be temporary, and cleared or modified land would be rehabilitated at the end of the proposed developments operational life. The impact footprint of the proposal would allow for dispersed agricultural activities to continue concurrently to wind farm operational.

The proposed development site is about 2.5 km from land zoned as E1- National parks and Nature Reserves. The objectives of this zone are to:
• enable the management and appropriate use of land that is reserved under the NPW Act or that is acquired under Part 11 of that Act.
• enable uses authorised under the NPW Act • identify land that is to be reserved under the NPW Act and to protect the environmental significance of that land
The only activities permitted in this zone are those authorised under the NPW Act. the proposed development would not impact land within the E-1 National Parks and Nature Reserves land zone.
The proposal does not contain heritage items identified under Schedule 5 – Environmental Heritage of the Cooma Monaro LEP 2013. A due diligence Aboriginal heritage assessment has been completed for the EWF and concludes that further investigation is required to confirm the former use of the site by Aboriginal people and the possible presence of archaeological deposits or scatters.
The indicative turbine layout is shown in Figure 2-4. Once the selection of wind turbine locations has been finalised, the earthworks required for site preparation, foundations and road construction would be assessed in accordance with Clause 6.1 – Earthworks of the Cooma Monaro LEP 2013 to minimise impacts on the environment, neighbouring uses and items of cultural and heritage significance.
Clause 6.3 – Terrestrial Biodiversity of the Cooma Monaro LEP 2013 relates to the conservation and protection of native flora, fauna and associated ecological processes. This clause is relevant to the proposal which is mapped in the Cooma Monaro LEP 2013 as possibly containing ecologically diverse habitat. A preliminary biodiversity review of the site has been undertaken in Section 6.2 of this report.
The Site also contains mapped areas of identified Riparian Land (Appendix C) and, accordingly, the provisions of Clause 6.6 – Riparian Land and Watercourses are applicable to the development. Clause 6.6 requires the consent authority to consider the impact of the proposal on:
• the water quality and flows within the watercourse • species, habitats and ecosystems of the watercourse • stability of the bed and banks of the watercourse • the free passage of fish and other aquatic organisms • any future rehabilitation of the watercourse and riparian areas.
The proposed development may adversely impact waterways and riparian areas. EWF would undertake further assessment to avoid, minimise and manage adverse impacts associated with the development.
The site includes areas mapped under Clause 6.8 of the Cooma Monaro LEP 2013 as having potential landslide risk due to the topography of the site. A geotechnical assessment would accompany the EIS to ensure the wind turbines and associated infrastructure are designed and sited to avoid or minimise environmental impact.
In principle, the proposal satisfies the relevant provisions of the Cooma Monaro LEP 2013 and overarching aims of the plan which promote environmental sustainability and the orderly and economic use of land.
5.5 Other policies and plans The matters to be addressed in the EIS are specified in the SEARs. In addition to the SEARs, key reference documents setting out planning criteria for wind farm projects include:
• NSW Government (2016) Wind Energy: Assessment Policy. Department of Planning and Environment, NSW Government, Sydney, New South Wales
• NSW Government (2016) Wind Energy: Visual Impact Assessment Bulletin. Department of Planning and Environment, NSW Government, Sydney, New South Wales

These documents have informed the assessments within this PEA, particularly the potential environmental impacts associated with the proposal.
5.6 Approvals required prior to commencement The EP&A Act states that various approvals and authorisations which would ordinarily apply to the development are not required for SSD. Aside from these exemptions, EWF would be required to obtain the following approvals prior to the commencement of the works:
• referral of proposed Controlled Action under Section 133 of the EPBC Act • reporting of tall structures to AirServices Australia, CASA and RAAF under the Civil Aviation Regulations 1988 • consent from Department of Lands • environmental Protection Licence from the EPA under Section 48 of the POEO Act • dangerous goods transportation licences for vehicles and drivers (if more than 500 L or 500 kg of dangerous goods
are required to be delivered to the Site) • over size over mass (OSOM) approvals for the transport of turbines and associated infrastructure to the site • an approval under Section 138 of the Roads Act 1993 to permit the construction of roadway connection to public
roads • water use approval under the Water Management Act 2000 to take water from the spring dam for concrete
batching and for construction activities occurring within 40 m of a waterway.

6 Assessment of key issues The purpose of this section is to identify potential environmental impacts specific to the context of the proposed Elysian development. The identified environmental constraints have informed the turbine layout of the proposed development. Key issues for consideration at the scoping stage of the environmental impact assessment (EIA) are based on the standard SEARs for wind energy projects and include:
• landscape and visual impact • ecological impact • Aboriginal and cultural heritage impact • access and transport of turbines and associated infrastructure and building material to the site • noise and vibration • aviation • telecommunications • health • bushfire • blade throw • water and soil impact • waste management.
Each of these key issues have been addressed in the following sections.
6.1 Landscape and visual assessment The Wind Energy: Visual Impact Assessment Bulletin (DPE, 2016) (VIA Bulletin) provides a guideline for consideration of visual impacts of a proposed wind farm. Visual impacts are an important consideration due to the colour, height, and typical location of wind farms within expansive rural areas, which are ordinarily characterised by open rural landscapes.
The VIA Bulletin suggests that the visual impact of turbines is relative to the characteristics and value of the existing landscape, the extent to which the landscape is to be changed and the perception by the community. Visual impact is predominately a qualitative assessment, which is difficult to numerically measure; however, studies of visual impact are typically based on a maximum visual extent of 8 km, beyond which turbines recede into the background (Sullivan et al., 2012; Bishop, 2000; Shang and Bishop, 1999).
To assist with determining viewpoints that should be considered for detailed visual assessment in the EIS, the VIA Bulletin relies on two preliminary assessment tools which measure visual magnitude, and cumulative impacts arising when multiple turbines are visible from a single receiver. This section provides consideration of these preliminary assessment tools to develop an understanding of the landscape within which the proposed Elysian development is to be located.
6.1.1 Landscape context
6.1.1.1 Topography & Local Context
The proposed development site follows a ridgeline of the Great Dividing Range, near Wadbilliga National Park (2.5 km to the east) and the Dangelong Nature Reserve (2.5 km to the west). The topography of the site is variable. North-south elevation ranges from about 1210 m AHD to 1062 m AHD, the highest point located near Tuross Road to the north of the development site. East-west elevation ranges from about 1210 m AHD to 1030 m AHD.
The proposed development site covers an area of about 1220 ha and is zoned RU1- Primary Production under the Cooma-Monaro LEP 2013. Much of the site is disturbed, with evidence of logging, clearing for agricultural practices and recent fire scars. The local area is predominantly used for agricultural purposes, specifically cattle and sheep grazing, with dwellings mostly clustered to the north and north-east of the proposed Elysian development site.
6.1.1.2 Vegetation cover
The proposed development site comprises several vegetation types at varying densities, ranging from rocky areas with limited canopy, dense areas with a 10-15 m tree canopy, flat cleared landscapes, boggy areas and regenerating areas that have been previously logged or have evidence of fire.

6.1.2 Assessment Requirements
The VIA Bulletin requires the following assessment to be undertaken as part of the PEA:
• community consultation to determine key landscape features and viewpoints within the area • mapping of key landscape features • outcomes of the application of the preliminary screening tools provided by the VIA Bulletin, which comprise:
− visual magnitude: consideration of the proposed height of turbines and distance from viewpoints where a turbine is located within the visual magnitude buffer, detailed consideration of the visual
impact is required for the proposed 230 m high turbines, a visual magnitude of 3100 m applies identification of host/stakeholder dwellings and non-associated neighbouring dwellings within 3100 m
of any turbine − multiple wind turbine tool - consideration of the cumulative visual impact of existing, proposed and approved
wind turbines as 60-degree segments within a 360-degree, 8.0 km radius from a viewpoint.
The VIA Bulletin also encourages the use of GIS software to develop a zone of visual influence, taking into consideration turbine location and local topography. This has also been included in our assessment.
6.1.3 Preliminary Consultation Outcomes The VIA Bulletin emphasises the importance of early consultation to:
• establish the key landscape features, areas of scenic quality and key public viewpoints valued by the community • allow the community to rank those features and scenic quality to high, moderate or low visual significance
Assessment of key issues
40
PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
• inform landholders about the proposed development area, likely corridors, preliminary turbine layouts and access routes
• inform the community about the proposed project, listen to community’s concerns and suggestions for alternative siting and location designs, and discus potential visual impacts.
The proponent has consulted with Cooma Monaro Shire Council to gain an understanding of valued local viewpoints and scenic quality. During a briefing meeting held with senior Council representatives on 22 January 2019, the following matters were discussed:
• wind energy development in the area can be divisive and Council/Councillors tend to field many queries about proposed developments from residents
• important to consult regularly with Council and keep elected representatives informed • Council representatives identified no notable public viewpoints in the proposed development area • residents of Numeralla should also be considered in consultation (along with those of Nimmitabel, Kybeyan and
Tuross).
Following preliminary consultation, a high-level map detailing key landscape features was developed. Figure 6-8 identifies the following key elements within the visual catchment:
• important public view points within the landscape • host dwellings • non-host dwellings • land zonings under Cooma Monaro LEP • Tuross Falls Lookout • Wadbilliga National Park • Kybeyan State Conservation Area • NSW State Forest Logging Area • public roads • transmission lines.
6.1.4 Preliminary Visual Assessment
6.1.4.1 Visual Magnitude Assessment
The visual magnitude is determined by a ratio of turbine height and distance. This assessment establishes the visual extent of turbines relative to dwellings and key public view points and is useful in identifying which viewpoints may require further assessment in the EIS.
Figure 6-9 shows the visual magnitude assessment based on a maximum wind turbine generator tip height of 230 m, creating a visual magnitude or extent of 3100 m. Dwellings and viewpoints within this 3100 m magnitude buffer required further consideration and assessment. The Tuross Falls Lookout ad Wadbilliga National Park and the Kybeyan State Conservation Area – Picnic Area are within the 8 km visual catchment.

6.1.4.2 Multiple Turbine Assessment
An assessment was undertaken to consider the cumulative impact on residential dwelling or key viewpoints where multiple wind turbines may be visible. This assessment was undertaken for all dwellings within 8.0 km of the proposed development, as per the VIA Bulletin.
Figure 6-11 shows residential properties and viewpoints within 8.0 km of a turbine for the proposed Elysian development. Note, that at the time of preparation of this PEA there were no other wind energy developments within 8.0 km of these dwellings. As such, the cumulative assessment only considered the turbines associated with the proposed Elysian development.

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
6.1.4.3 Zone of Visual Influence
A preliminary zone of visual influence was established based on the maximum wind turbine tip height of 230 m and basic local topography. The result of this assessment is provided in Figure 6-12. Note, this assessment does not consider screening by vegetation and only uses publicly available, 10 m topographical contours rather than confirmed survey data. Therefore, it is likely to be an overestimate. Nonetheless, due to the surrounding topography and ridgelines, this assessment confirms that wind turbines are unlikely to be visible from the dwellings closest to the wind farm, particularly along the northern extent of the proposed development site.
With reference to the Bulletin, sensitive land designations include:

No residences in the localities relevant to the proposed development are considered to be within sensitive lands as described in the Bulletin. The Tuross Falls Lookout at Wadbilliga National Park and the Kybeyan State Conservation Area – Picnic Area are within the 8km visual catchment and are considered to be sensitive lands. However, as outlined in the previous section, it is unlikely that the turbine would be visible from these locations due to aspect, topography, elevation and screening from vegetation.

6.1.6 Conclusions and need for further assessment
Of the 34 dwellings identified within the visual magnitude buffer (3100 m):
• 3 (~9%) dwellings would not have visibility of any turbines • 4 (~12%) dwellings would have visibility of one turbine only • 7 (~21%) dwellings would have visibility of up to two turbines • 2 (~6%) dwellings would have visibility of up to three turbines • 18 (~53%) dwellings would see four or more turbines.
Of the 17 dwellings identified between 3100 m and 8000 m from any turbine, three have views of multiple turbines within more than one 60 degree viewshed.
Further detailed assessment of landscape and visual impacts to these and other relevant dwellings and public viewpoints would be undertaken for the EIS.

6.2 Noise and vibration Establishing wind energy developments is a key component of the NSW Government’s initiative to increase renewable energy generation across the state. Wind energy generation requires reliable wind resource, but areas that support this are often quiet, rural areas.
Research has shown that wind energy operations in Australia typically have limited impact on the ambient noise environment within a locality. National Health and Medical Research Council (NHMRC) Information Paper: Evidence on Wind Farms and Human Health (2015) concluded that:
“There is consistent evidence that noise from wind turbines―whether estimated in models or using distance as a proxy―is associated with annoyance, and reasonable consistency that it is associated with sleep disturbance and poorer sleep quality and quality of life. However, it is unclear whether the observed associations are due to wind turbine noise or plausible confounders.”
EWF acknowledge that the DP&E Wind Energy: Noise Assessment Bulletin requires a noise impact assessment (NIA) to be provided to determine the extent of noise impact for a wind energy development proposal. This would be undertaken by a specialist noise and vibration consultant during preparation of the EIS.
6.2.1 Applicable legislation
The following legislation and guidelines are applicable to the consideration of noise impacts associated with the proposed development:
• Wind Energy: Noise Assessment Bulletin (2016), NSW DP&E • Noise Policy for Industry (2017), NSW EPA • Interim Construction Noise Guidelines (2009), NSW DECC • Road Noise Policy (2011), DECCW • Noise Guidelines for Wind Farms (2009) South Australian EPA • Guidelines for Community Noise (1999) World Health Organisation • Assessing vibration: a technical guideline (2006), NSW Government.
The South Australian EPA Noise Guidelines for Wind Farms 2009 (SA EPA Guidelines) have been adopted by the DP&E in the Wind Energy: Noise Assessment Bulletin (DPE, 2016b). These documents set a base noise criterion of 35 dB(A) and allow for more elevated criteria in circumstances of higher background noise.
6.2.2 Existing environment Wind turbines create aerodynamic noise and mechanical noise. Aerodynamic noise is generated by airflow around the rotating blades of the turbine, creating a swishing sound. Mechanical noise is associated with gearbox and transmission paths within the nacelle housing. There may also be humming and other operational noises from substations.
Noise criteria defined in the Wind Energy: Noise Assessment Bulletin (DP&E, 2016) include:
“The predicted equivalent noise level (LAeq, 10 minute), adjusted for tonality and low frequency noise in accordance to these guidelines, should not exceed 35 dB(A) or the background noise (LA90, 10 minute) by more than 5 dB(A), whichever is the greater, at all relevant receivers for wind speed from cut-ins to rates power of the wind turbine generator and each integer wind speed in between.”
Minimum noise criteria defined in the Wind Energy: Noise Assessment Bulletin (DP&E, 2016) are:
• 35 dB(A) for non-stakeholder dwelling • 45 dB(A) for stakeholder dwellings.
In NSW, the criteria for acceptable noise levels (35 dB(A)) is generally achieved through setback distances between 800 m and 1500 m (NSW, 2016b). These recommendations do not account for specific site conditions, such as landscape features, topography and aspect. Figure 6-13 shows the average distances at which compliance with different noise standards would be achieved.

Figure 6-13. Conceptual diagram showing representative distances for noise objectives (DPE, 2016b)
The Wind Energy: Noise Assessment Bulletin (DP&E, 2016) recommends that the NIA include noise modelling at each receiver location, including stakeholder and non-stakeholder dwellings. As the ultimate turbine locations for the proposed Elysian development have yet to be determined, noise modelling cannot be undertaken, and therefore has not been included in this PEA. As such, the Guidelines for Community Noise (WHO, 1999) were deemed the most appropriate to apply to the PEA.
The WHO guidelines permit:
• a night-time noise level of up to 45 dB(A) • a noise level of up to 5 dB(A) over background noise, for residences which have entered into an agreement with
the wind farm developer/operator.
Notably, the criteria are not intended to restrict wind farm noise to inaudible levels but rather provide indicative distances to achieve acceptable noise levels for environmental and personal health.
There is often a perception that noise generated by wind turbines can be discriminated from noise generated by standard rural and agricultural practices (e.g., from farm machinery operation, farm vehicles, bores and pumps, livestock). Figure 6-14 provides a simplified schematic of the noise impact associated with wind turbine infrastructure, including a comparison with other types of noise generated in a rural environment. Given that the nearest dwellings are more than 500 m from the proposed Elysian turbine locations, the noise impact to dwellings from the proposed development is anticipated to be below the WHO 45dB(A) guideline value.

Figure 6-10 and Figure 6-11 presented dwelling within 3100 m and 8000 m, respectively. The closest non-stakeholder dwelling is 510 m from the nearest turbine. The nearest stakeholder dwelling is 550 m from the nearest turbine.
A preliminary noise assessment was prepared to predict the potential noise levels of the proposed development site at nearby sensitivity receptors within 12 km of a proposed turbine location. the preliminary noise assessment can be found at Appendix D.
The purpose of the preliminary assessment the potential operational noise levels of the proposed WTGs at nearby sensitive receptor locations. The information from preliminary noise assessment be used to inform future planning assessment of the proposed wind energy farm.
A conservative sound power level of 109 dB(A) was used for the preliminary calculations, as it is common for new WTGs installed in Australia to be fitted with serrated trailing edges (STEs), which assist in reducing sound power levels. The predictions are based on the WTGs operating at rated power and for the receptor being downwind of the wind farm. Lower noise levels would generally be expected for lower wind speeds and for situations where the receptor is not downwind of the wind farm.
A summary of the preliminary noise predictions is provided in Table 6-2. The highest predicted noise levels were 41 dB(A) which occurred at two locations. These predictions are within the Wind Energy: Noise Assessment Bulletin and WHO guidelines. A preliminary noise contour map is provided in Figure 6-15. Please note that this assessment has not taken into consideration background noise levels and noise dissipation that would occur through environmental interactions.

The applicable construction noise goals for the wind farm are provided within the NSW Interim Construction Noise Guideline. This guideline states that ameliorative measures may be required during construction to protect the acoustic amenity of residents where construction is to commence for an extended period, or in circumstances where noise sensitivity may be greater.
Construction of the proposed Elysian development is anticipated to take 18-24 months. Intensive construction works would be centred on small areas near the base of each turbine, therefore construction noise is unlikely to continually impact any one residential property.
Construction will generally be undertaken during daytime hours; however, some OSOM deliveries may need to occur at night to minimise traffic impact. Night deliveries will be restricted to single, isolated events and the only dwellings likely to be adversely affected are the stakeholders. As these are stakeholder dwellings, they should reasonably expect some disturbance during construction of the proposed development.
Rock crushing may also be required to create raw aggregate for construction or improvements to internal roads within the proposed development site. If required, this will be undertaken in the concrete batching area located near turbine 30 and would only occur during daytime hours.
Construction (and decommissioning) activities are temporary, therefore noise associated with these works will neither be extensive, nor cause ongoing nuisance to residents. Moreover, the separation between the proposed turbine locations and the nearest non-stakeholder residences, provides a buffer between the proposed development site and residential properties to maintain appropriate noise levels during construction works.
Vibration
Activities such as truck deliveries, blasting and rock crushing may cause some temporary and local vibration; however, these activities would be temporary and of short-duration. The specifics are yet to be determined and as such would be assessed during the EIS. It is assumed that a small number of dwellings (both stakeholder and non-stakeholder) would experience limited, temporary vibration impacts during construction and decommissioning.
The Assessing vibration: a technical guideline (DP&E, 2006) provides guideline values for continuous, transient and intermittent vibration events that are based on a vibration dose value (VDV) rather than a continuous vibration level. The VDV is dependent upon the level and duration of the short-term vibration event and the number of events occurring during the daytime or night-time period. Table 6-3 presents recommended VDVs for vibration of an intermittent nature (i.e., construction works where more than three distinct vibration events occur).

Structural damage vibration limits are based on Australian Standard AS 2187: Part 2-2006 Explosives – Storage and use - Part 2: Use of Explosives and British Standard BS 7385 Part 2-1993 Evaluation and measurement for vibration in buildings Part 2. These standards provide frequency-dependent vibration limits related to cosmetic damage, noting that cosmetic damage is very minor in nature, is readily repairable and does not affect a building’s structural integrity. The recommended vibration limits from BS7385 for transient vibration for minimal risk of cosmetic damage to residential and industrial buildings is shown in Table 6-4.

6.2.3 Summary of findings and potential impacts
The PEA noise interrogation for the proposed Elysian development is summarised as:
• the layout of the proposed Elysian development has yet to be determined, and as such noise modelling in accordance to the Wind Energy: Noise Assessment Bulletin could not be undertaken to inform the PEA. Modelling would be undertaken to inform the EIS once the turbine layout has been finalised
• all non-stakeholder and stakeholder dwellings are located more than 500 m from any of the proposed turbines, which accords with the WHO guidelines
• the topography of and adjacent to the site in the north-east may provide natural noise attenuation to buffer noise propagated by the turbines, especially to the receivers along Tuross Road
• receivers may experience elevated noise levels during construction of the proposed Elysian development; however, construction activities are temporary, and over a short-duration, and would be conducted in accordance to the relevant construction noise and vibration guidelines
• noise levels and perceived noise levels may fluctuate in response weather conditions, e.g., high wind speeds would result in faster turbine rotation, which may lead to higher mechanical noise levels
• wind speed and direction may influence affect noise levels at receiver locations • noise generated by wind turbines can often not be discriminated from noise generated by standard rural and
agricultural practices (e.g., machinery operation, farm vehicles, bores and pumps, livestock) • some vibration impacts associated with the construction of the wind farm may occur; however, the proposed
development site is relatively isolated from nearby properties, which assists in the separation of the source of any construction related vibrations from sensitive receivers
• aside from impacts during construction, operation of the proposed development is not anticipated to result in ongoing vibration impacts.
6.2.4 Recommendations and further assessment Based on the findings of the noise assessment presented in this PEA, key recommendations for the next stage of environmental assessment include:
• ongoing community engagement with stakeholder and non-stakeholder dwellings • characterisation and refinement of background noise landscape through input assumptions, e.g., wind turbine
sound power level, ground terrain, topography, hardness, etc. • baseline noise monitoring at relevant receptors to quantify the existing ambient noise environment, including wind
speed regression • the proponent should investigate noise optimised operation of the wind turbines • targeted baseline noise assessment and modelling at receiver sites to fully understand the environmental risks and
impacts that may arise from the proposed Elysian development • the wind farm noise predictions should be updated to in accordance with the finalised layout and WTG selections

• carry out background noise monitoring at the nearest receptors to establish a baseline against which future operational monitoring can be undertaken to verify compliance
• develop and implement appropriate noise agreements are in place with associated receptors • construction and decommissioning timetables should schedule work within standard hours to limit noise and

6.3 Biodiversity An ecological investigation into the proposed Elysian development was prepared by SMEC Australia in 2019 and included preliminary fauna and habitat assessments. A summary of key findings is presented below.
6.3.1 Applicable legislation and literature review The biodiversity component of the PEA is being assessed under the following legislation:
• Environmental Planning and Assessment Act 1979 (EP&A Act) • Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) • Biodiversity Conservation Act 2016 (BC Act) • OEH (2013). Compilation map: Biometric vegetation types and endangered ecological communities of the
Shoalhaven, Eurobodalla and Bega Valley local government areas. A living map. Version 2.0. Technical Report. NSW Office of Environment and Heritage, Queanbeyan.
• Tozer et al. (2010) Native vegetation of southeast NSW: A revised classification and map for the coast and eastern tablelands. Cunninghamia 11(3): 359-406.
6.3.2 Existing environment
6.3.2.1 Desktop review
The likelihood of occurrence for threatened plant and animal species, populations and ecological communities was determined for a 10 km radius around each of the proposed wind turbines. The ecological records were obtained from the Office of Environment and Heritage (OEH) Atlas of NSW Wildlife database and the Commonwealth Department of the Environment and Energy (DOEE) Protected Matters Search Tool. These records and an assessment of the habitat within the study area were used to determine the likelihood that any listed threatened species, populations, ecological communities, or their habitats could occur.
A review of the existing vegetation mapping was also conducted to determine the vegetation communities predicted to occur around the proposed wind farm. Two broad-scale mapping sources were reviewed:
• Native vegetation of south-east NSW: a revised classification map for the coast and eastern tablelands. Version 1.0. (Tozer et al., 2010)
• OEH’s Compilation Map: Biometric Vegetation Types and Endangered Ecological Communities of the Shoalhaven, Eurobodalla and Bega Valley Local Government Areas (OEH, 2013).
Vegetation communities described in the broad-scale vegetation mapping were cross referenced with potential PCT determinations using OEH’s BioNet Vegetation Classification (VIS 2.1) and Vegetation Types database.
6.3.2.2 Site inspection
An initial inspection of the proposed development site was undertaken by two SMEC ecologists on the 12 December 2018. The purpose of the inspection was to gain a basic understanding of the biodiversity features of the study area to inform the detailed design of future surveys. A rapid assessment of broad vegetation types, patterns, and conditions present onsite was also carried out.
The site inspection revealed that some of the proposed wind farm site is recovering from a fire, resulting in dense epicormic growth on the larger eucalyptus trees. Recent logging of timber has also occurred in this area.
A second site inspection was carried out in May 2019. This inspection identified two areas of vegetation clearing in the areas that the proponent had installed the meteorological monitoring masts. The vegetation clearing near the southern mast involved the removal of several large canopy trees. The clearing near the northern mast comprised an area of about 1 hectare and cleared all vegetation community strata. The vegetation cleared near the northern mast appears to conform to the scientific determination of Tablelands Basalt Forest EEC; however, a full assessment was not undertaken.
Neither the installation of the meteorological masts, nor the clearing associated with these areas, were assessed as part of this PEA. The proponent has advised SMEC that they had the legal right to clear these areas. The proponent also advised SMEC that the main host landowner is planning on returning overgrown and neglected areas of their land to grazing land/pasture, which would involve clearing of regrowth, trees and shrubs. These activities are independent of the wind farm development and have not been considered by SMEC.

6.3.2.4 Threatened ecological communities
The desktop assessment identified seven threatened ecological communities predicted to occur within 10 kilometres of the proposed Elysian development. A brief description of each threatened community and its status under the EPBC and BC Acts has been provided below.
1. Montane Peatlands and Swamps of the New England Tableland, NSW North Coast, Sydney Basin, South East Corner, South East Highlands and Australian Alps Bioregions Conservation status: Endangered under both the EPBC and BC Acts
The Montane Peatlands community with sediments that are peaty or have a large amount of organic sediments. These sediments usually occur in poorly drained areas or in the headwaters of streams and creeks. This community is comprised of a variable layer of shrubs with soft-leaved sedges, grasses and forbs. Unusually for a wetland, this community may contain more than trace-amounts of the hummock peat-forming mosses, Sphagnum spp.
Common shrub species include - Baeckea gunniana, B. utilis, Callistemon pityoides, Leptospermum juniperinum, L. lanigerum, L. myrtifolium, L. obovatum, L. polygalifolium, Epacris breviflora, E. microphylla and E. paludosa.
Common sedges and grasses include - Carex appressa, C. fascicularis, C. gaudichaudiana, Poa costiniana and P. labillardieri.
Other forbs and herbs that have been recorded in this community include - Drosera spp., Geranium neglectum, Gratiola spp., Mitrasacme serpyllifolia and Ranunculus spp.
2. Natural Temperate Grassland of the South Eastern Highlands Conservation status: Critically Endangered under the EPBC Act This community is confined to the Southern Tablelands where it has been recorded at a range of topographical positions, on a variety of substrates and at various altitudes (anywhere from 500 m to 1200 m above sea level). The community is often found with cold air inversions that inhibit the growth of trees.
Natural Temperate Grassland is a grassland community dominated by a range of perennial grasses such as Poa sieberiana (Snowgrass), Themeda triandra (Kangaroo Grass) and River Tussock species. In highly intact sites, this community can contain a large range of herbaceous species from many plant families, including daisies (Asteraceae), peas (Fabaceae), lilies (Liliaceae)and orchids (Orchidaceae).
3. Tableland Basalt Forest in the Sydney Basin and South East Highlands Bioregions Conservation status: Endangered under the BC Act Tablelands Basalt Forest has been recorded on loam or clay soils associated with basalt or less frequently, alluviums and fine-grained sediments and granites that produce fertile soils. This community is found at altitudes between 600 m and 900 m above sea level, on hilly and undulating terrain with mean annual rainfall varying between 750 mm and 1100 mm.
Tableland Basalt Forest is an open eucalypt forest with a variety of canopy species including - Eucalyptus viminalis, E. radiata, E. dalrympleana subsp. dalrympleana and E. pauciflora. The shrub layer is sparse consisting of species such as Acacia melanoxylon, A. dealbata and the smaller Rubus parvifolius. The ground cover varies considerably because of past disturbances such as agricultural clearing, grazing and fires.
4. Tablelands Snow Gum, Black Sallee, Candlebark and Ribbon Gum Grassy Woodland in the South Eastern Highlands, Sydney Basin, South East Corner and NWS South Western Slopes Bioregions Conservation status: Endangered under the BC Act This community occurs as an open forest or woodland, or as a derived grassland where the trees have been removed but the ground layer has remained intact. The community has commonly been recorded on valley floors, the margins of frost hollows and on the foot slopes and undulating hills. It occurs on a variety of substrates, including basalt, granite, colluvium and alluvium.
As the name suggests the main tree species are Eucalyptus pauciflora (Snow Gum), E. rubida (Candlebark), E. stellulata (Back Sallee) and E. viminalis (Ribbon Gum) which can occur either alone or as a mixed assemblage. A shrub layer is often present including species such as Melicytus sp. 'Snowfileds' (Gruggly-bush) and Melichrus urceolatus (Urn Heath). A grassy ground-cover is common in this community consisting of Themeda australis (Kangaroo Grass), Poa spp. (snow-grasses), Austrostipa spp. (spear-grasses) and Rytidosperma spp. (wallaby-grasses). Other herb and forbs such as Leptorhynchos squamatus (Scaly-buttons), Chrysocephalum apiculatum (Common Everlastings) and Asperula conferta (Native Woodruff) occur in this community.

5. Araluen Scarp Grassy Forest in the South East Corner Bioregion Conservation status: Endangered under the BC Act This community occurs on sandy loams derived from granite, usually on steep slopes between 200 and 700 metres in altitude. Mean rainfall is approximately between 890 and 1000 mm annually. The structure of the community varies depending on land management practises; the overstory and/or mid-storey may be absent. Araluen Scarp Grassy Forest in the South East Corner Bioregion an open forest or grassy woodland dominated by Maiden's Gum (Eucalyptus maidenii), Yellow Box (E. melliodora) and Forest Red Gum (E. tereticornis) in the canopy. Rough-barked Apple (Angophora floribunda), White Stringybark (E. globoidea) and Black Wattle (Acacia mearnsii) are common associated overstorey species. An open shrub layer may contain Tree Violet (Hymenanthera dentata), Sweet Pittosporum (Pittosporum undulatum) and various vines and climbers. The grassy ground-layer is generally sparse and may contain species such as Weeping Grass (Microlaena stipoides), Common Tick-trefoil (Desmodium varians), Creeping Beard Grass (Oplismenus imbecillis), Sickle Fern (Pellaea falcata) and Prickly Starwort (Stellaria pungens). Many other plant species are likely to occur, as outlined in the scientific determination.
6. Upland Wetlands of the New England Tablelands (New England Tableland Bioregion) and the Monaro Plateau (South Eastern Highlands Bioregion) Conservation status: Endangered under the EPBC Act This community occurs on basaltic, occasionally granitoid or silcrete derived soils in the New England and Monaro Tableland regions, as their name suggests. The wetlands occur in natural depressions ranging from semi-permanent to ephemeral. Persistence depends on hydrological variations in the catchment, rainfall and disturbances. The community structure ranges from closed to medium-dense sedge land and grasslands, occurring on the shores of open water, or extending across shallow or dry wetlands. Plant diversity ranges depending on persistence of the wetland. No trees or shrubs occur in this community.
7. White Box-Yellow Box-Blakely's Red Gum Grassy Woodland and Derived Native Grassland Conservation status: Critically Endangered under the EPBC Act and Endangered under the BC Act This community is found on relatively fertile soils of the tablelands and western slopes of NSW. The community occurs between altitudes of 170 m and 1200 m and receives between 400 and 800 mm of rain annually. This community is structured as a woodland, and occasionally a forest formation. Eucalyptus albens, E. melliodora and E. blakelyi characterise the over storey. Intact sites contain a high diversity of plant species at all strata levels, particularly grasses and a very high diversity of herbs. Most common understory species include Kangaroo Grass (Themeda australis), Poa Tussock (Poa sieberiana), wallaby grasses (Austrodanthonia spp.), spear-grasses (Austrostipa spp.), Common Everlasting (Chrysocephalum apiculatum), Scrambled Eggs (Goodenia pinnatifida), Small St John's Wort (Hypericum gramineum), Narrow-leafed New Holland Daisy (Vittadinia muelleri) and blue-bells (Wahlenbergia spp.).
6.3.2.5 Soil landscapes
The soils occurring within the project boundary are from the Anembo, Round Hill, Duck Hole Creek, Upper Tuross and Celeys Creek soil landscapes. A description of each landscape in context of the wider locality has been provided.
Anembo
The Anembo soil landscape occurs on undulating rises, plains and broad valley flats on the granitics of the Upper Kybeyan River and Kydra Creek, the Jibolaro Creek-Guinea Creek area, Boggy Plain and the Upper Cowra Creek – Celeys Creek area. Shallow soils (<50 cm) are well-drained Earthy sands while moderately deep soils (50 – 150 cm) are well-drained Red Podzolic Soils and Red Earths on crest and upper slopes. Yellow Soloths, poorly drained Brown Podzolic soils and Gleyed Podzolic soils can occur between 50 and 150 cm on mid-slopes and lower slopes. Deeper soils occur as poorly to very poorly drained Alluvial soils and Brown clays, especially on alluvial flats and drainage depressions (OEH, 2019).
Round Hill
The Round Hill soil landscape occurs on moderately inclined to steep hills overlaying various granitics. This soil landscape has been recorded downstream of Boggy Plain near the Kybeyan Trig area with isolated examples in upper Kydra Creek, the Kybeyan River, the Numeralla River and near Peak View. Soils less than 15 cm from the surface have been recorded

as rapidly drained Lithosols. Slightly deeper soils (30 – 90 cm) change to rapidly to well-drained Earthy Sands and well-drained Yellow Earths. Soils deeper than 80 cm occur as Red Podzolic Soils or as Yellow Podzolic soils on moderately steep slopes (OEH, 2019).
Duck Hole Creek
The Duck Hole Creek soil landscape occurs on undulating hills and the rises of the Adaminaby Group sediments and metasediments. Example locations include the hills between Waratah and Duck Hole Creek, and the area between upper Greens Creek and Mowitts Swamp. Shallow soils (<70 cm) consist of moderately well-drained Red Earths, Brown Earths, and as structured Red Earths on crests and upper slopes. Moderately deep soils (>80 cm) occur as moderately drained Red Earths and Yellow Soloths on the mid-slopes of hills. On lower slopes and drainage depressions, moderately deep soils occur as imperfectly drained Yellow Soloths and Gleyed Yellow Duplex Soils (OEH 2019).
Upper Tuross
Adaminaby Group sediments and metasediments occurring as part of rolling low hills and hills underlie the Upper Tuross soil landscape. This soil landscape has been mapped on the Kybeyan Range from upper Greenlands Swamp to the upper reaches of the Kybeyan River. Shallow and moderately deep soils are characterised by moderately well-drained stony Brown Earths with Red Earths occurring on crests and upper slopes. The moderately well drained Brown Earths extend into depressions and drainage lines (OEH, 2019).
Celeys Creek
The Celeys Creek soil landscape occurs on low hills supported by the granitics of the Celeys Creek area, the upper Numeralla River, Kybeyan, Big Badja River and Kydra Creek area. Well-drained Earthy Sands, Lithosols and Massive Brown Earths occur within 30 cm of the surface. Well-drained Yellow Podzolic Soils can also be found within 100 cm of the surface on crest and upper slopes. Moderately deep to deep (>100 cm) soils comprise of poorly drained Black Earths with Alluvial Soils occurring on flats and drainage lines (OEH, 2019).
6.3.2.6 Threatened flora
No threatened flora species were recorded during the site inspection. However, 13 threatened flora species are considered to have a moderate to high likelihood of occurring within the study area (Table 6-6).

No NSW-listed vulnerable fauna species or federal listed species were recorded during the site visit. However, large hollow-bearing trees were identified within the proposed development site. These may serve as habitat for threatened species. There is also potential for vegetation within the study area to be classified as koala habitat; this includes ‘potential koala habitat’ based on identification of feed tree species in accordance with State Environmental Planning Policy No 44 – Koala Habitat Protection.

6.3.3 Potential impacts
Based on the findings of the desktop assessment and site inspection, the potential impacts to biodiversity from the proposed Elysian development may include:
• the project will directly and indirectly impact four threatened ecological communities through the direct clearing of vegetation (Figure 6-17). Vegetation removal that may be required for the proposed works would likely contribute to loss of parts of the TECs affecting habitat and potentially resulting in further fragmentation of communities within the locality
• hollow-bearing trees provide habitat for threatened species such as forest owls, woodland and forest birds and microbats, which may occur within the study area. As such, the proposal has the potential to remove these tree hollows impacting on threatened species that may utilise them as habitat
• construction of turbines and their access roads may clear logs and debris used by threatened flora such as the Spotted-tailed Quoll (Dasyurus maculatus) and Striped Legless Lizard (Delmar impar)
• the operation of the wind turbines has the potential to directly impact upon threatened birds and bats. Direct impact would take the form of birds and bats being struck by the turbines blades when moving within or through the wind farm
• the wind farm may create a barrier to movement along the forests of Eastern Australia. Species such as the White-throated Needle-tail (Hirundapus caudacutus) will migrate latitudinally across Australia, preferentially moving over forested areas such as Wadbilliga National Park
• the wind farm may create a barrier to movement longitudinally for some threatened bird species. The Flame Robin (Petroica phoenicea) for example, can migrate to the coastal lowlands in the winter
• priority weeds are likely to occur in parts of the study area. Continued weed invasion and encroachment could have potentially severe consequences for the habitat of flora and fauna occurring in the area
• there is also potential for vegetation within the study area to be classified as koala habitat; this includes ‘potential koala habitat’ based on identification of feed tree species in accordance with State Environmental Planning Policy No 44 – Koala Habitat Protection
• potential sediment, nutrient and pollutant run-off into adjacent vegetation and fauna habitat • noise and vibration disturbances to fauna • temporary light disturbance to fauna during the construction stage of the work.

6.3.4 Recommendations
Impacts to biodiversity is considered a key issue for the SEARs and a detailed biodiversity impact assessment would accompany all stages of the design and EIS. Biodiversity impacts related to the proposal would be assessed in accordance with section 7.9 of the BC Act, the Biodiversity Assessment Method (BAM) and documented in a Biodiversity Development Assessment Report (BDAR). The BDAR must include information in the form detailed in the BC Act (s6.12), Biodiversity Conservation Regulation 2017 (s6.8) and BAM, unless OEH and the Department of Environment and Planning determine that the proposed development is not likely to have any significant impacts on biodiversity values. A referral to the Department of Environment and Energy may be required to satisfy assessment obligations under the EPBC Act.
Further assessment of the proposed Elysian development’s impacts on biodiversity would include:
• a detailed impact assessment as required under the BC Act and the EPBC Act for any threatened species, populations and ecological communities considered likely to be present in the study area. It is important to note that there is currently no bilateral agreement for biodiversity assessments that meet the requirements under both the BC Act and EPBC Act. As such, a separate assessment to satisfy EPBC assessment requirements may be needed.
• investigations as to potential for design to avoid impacts on TECs and any other threatened biota (or their habitat), as far as practicable.
• identification of PCTs requiring offsetting. • measures of the impact to ecosystem credits and species credits of the project on biodiversity values at the
development site • credit profiles for ecosystem credits and species credits at the development site. • a credit price for payment to the Biodiversity Conservation Trust (BCT) as an indication of offset costs. • level 1 bird and bat strike assessment (at a minimum).

6.4 Traffic and transport The standard SEARs for wind energy development require the consideration of traffic and transport impacts associated with the construction and operation of any wind farm. The ensuing EIS would be accompanied by a detailed traffic and transport study, including assessment of type and number of vehicle movements, impacts on road network functionality, and identification of required road upgrades and modifications.
As the proposed Elysian development is still in the preliminary design phase, the receival port and haulage route for delivery of wind turbines and associated infrastructure to the proposed development site has not yet been confirmed. However, it is anticipated that large components likely to be manufactured overseas, such as the wind turbine generators, would enter Australia at Port Kembla. The Port of Eden may be used as an alternate entry point; however, while the route from Eden to the development site has been assessed (albeit for smaller length blades) storage at the Port of Eden is limited. As such, the Port of Eden is not being considered at this time.
Similarly, the source and location of materials such as sand, that would be used for construction purposes, is not yet known. Noting these limitations, this section of the PEA will provide a high-level overview of the information that would be prepared and submitted with the EIS for the Elysian Wind Farm.
6.4.1 Applicable legislation
The relevant statutory framework for the consideration of traffic and transport impacts of the proposed development include: • Roads Act 1993 • Dangerous Good (Road and Rail Transport) Act 2008 • Road Transport (Mass, Loading and Access) Regulation 2005 • NSW Road Noise Policy.
6.4.2 Existing environment It is anticipated that the wind turbine infrastructure for the proposed Elysian development would be received through Port Kembla and transported to the site via a feasible route capable of accommodating oversize and over-mass (OSOM) vehicles. The selected transportation route would be confirmed in consultation with the haulage contractor, NSW Roads and Maritime Service, and Snowy Monaro Regional Council.
There is an approved OSOM transport route from Port Kembla to Cooma, via the Hume Highway, Federal Highway, Sutton Road and Monaro Highway. Arrangements would need to be made with Snowy Monaro Regional Council for the transit of goods on local roads from Cooma to the proposed Elysian development site.
The route would likely comprise: Tom Thumb Road, Springhill Road, Masters Road, Southern Freeway, Mt Ousley Road, Picton-Wilton Road, Hume Highway, Federal Highway, Majura Road, Monaro Highway, Polo Flat Road, Snowy Mountains Highway, Steeple Flat Road, Old Bega Road, Kybeyan Road. This route is shown in Figure 6-18.
Other wind energy developments that were proposed in proximity to Elysian have assessed this route for suitability of delivering of wind turbine components to the project site. These developments were proposing blades slightly smaller than those proposed for Elysian, but as an indication the route assessment highlighted that several intersections would require upgrades to allow clearance for blades of this length. These intersections were primarily on exit from Port Kembla through Mount Ousley Road, and entry to the site along through Cooma, Steeple Flat and Old Bega Road. Once the wind turbine components have been selected and exact dimensions of all equipment is known, a detailed route study and road survey would be undertaken.

6.4.3 Potential impacts Historical and existing development and commercial activities in the region include the Snowy Hydro scheme and commercial logging, which suggests that local road infrastructure would be able to accommodate turbine and other infrastructure deliveries with or only minor modification. For example, the most likely route from Cooma to the proposed Elysian development site requires a left turn from Polo Flat Road onto Numeralla Road (Figure 6-20). This intersection would likely require modification to accommodate delivery of the proposed development infrastructure.
Alternatively, goods may be transported to Nimmitabel via the existing OSOM route; however, this route would also require a sharp (90-degree) left turn from Monaro Highway onto Bombala Street (Figure 6-21). Further investigations would be required to confirm if this intersection could accommodate the delivery of the proposed development infrastructure. This intersection has established buildings and round-a-bout, therefore any required modification to it could be costly.
The remainder of the likely haulage route does not appear to have any obstructions. Some minor modifications would be required at the site entry points from Kybeyan Road. There may also be requirements for culvert and bridge upgrades along the proposed route. These would be discussed with Council or the relevant authority once identified.

6.5 Hazards and Risks The following section provides a preliminary assessment of hazards and risks, as identified in the SEARs and the NSW Wind Planning Guidelines. This assessment has been used to identify further areas for investigation in the EIS, and aspects that may require input from specialist consultants.
6.5.1 Aviation SMEC has undertaken a preliminary review of the potential adverse impact of the proposed Elysian development on aeronautical operations in the area (Table 6-8). A detailed assessment in accordance with the Civil Aviation Safety Regulations 1998 (CASA Regulations) would be undertaken as part of the EIS.
6.5.1.1 Location and potential impacts
The proposed Elysian development site is approximately 115 km south of Canberra Airport, 50 km east of Snowy Mountains (Cooma) Airport, and 80 km north-west of Merimbula Airport (Figure 6-22). A detailed assessment of relative blade height would accompany the formal aviation assessment as part of the EIS, once a LiDAR survey of the site is completed. Potential aeronautical impacts on local aerodromes are summarised in Table 6-8.
Table 6-8. Potential aeronautical impacts on local aerodromes (Cooma, Merimbula)
IMPACT DISCUSSION OUTCOME
Light emission and reflection
The CASA Manual of Standards (MOS) indicates that light emission and reflection from infrastructure may impact aerodromes within 6 km of a wind farm.
The proposed Elysian development site is not located within 6 km of an aerodrome. No further consideration is required.
Obstacle Limitation Surfaces (OLS)
OLS set by the CASA MOS for Cooma and Merimbula Airports is 15 km from the runway end.
The proposed Elysian development site is more than 15 km from the runway at Cooma and Merimbula Airports. No further consideration is required.
Procedures for Air Navigation Services – Aircraft Operations Surfaces (PANS-OPS)
The location of the proposed Elysian development presents a potential hazard to aviation under the International Civil Aviation Organisation (ICAO) Document 8168 Ops/611.
Further consultation would be required with the Civil Aviation Safety Authority (CASA) during the preparation of the EIS.
Minimum Safe Altitude (MSA) Surfaces
The proposed Elysian development site is located within the MSA surface buffer around Cooma Airport and is on the periphery of the MSA surface area around Merimbula Airport.
Further consultation would be required with the Civil Aviation Safety Authority (CASA) during the preparation of the EIS.
Distance Measuring Equipment (DME) / GPS Arrival Surfaces
DME / GPS Arrival Surfaces allow aircraft to step down in altitude after passing critical obstructions on route to a destination airport.
The proposed Elysian development site may be located within the Arrival Sector B surface for Cooma Airport. The maximum proposed turbine height infringes the Arrival Surface.
Further consultation would be required with the Civil Aviation Safety Authority (CASA) during the preparation of the EIS.

Minimum obstacle clearance (MOC) is based on the crusing altitude of existing flight paths (Figure 6-22) and the maximum turbine height above sea level. It is important to understanding aviation risk as it provides an assessment of the maximum height of the wind turbines against the minimum safe flying altitudes of the routes. The maximum elevation of the tubrines must also be assessed against the lowest safe altitude (LSAlt) for nearby flight paths to detemine whether modification to the flight path or altiude is required.
The preliminary review undertaken by SMEC has identified that the proposed Elysian development site is located within proximity of air route W716: Canberra – Mallacoota. A detailed survey of the site has not yet been undertaken, therefore the relative height of turbines above ground level cannot be calculated accuately at this time. This will be undertaken as part of the complee aeronautical assesssment that will accompany the EIS.
6.5.1.2 Recommendations
During preparation of the EIS further consultation will be required with AirServices Australia and CASA during the preparation of the EIS due to the proximity of the proposed Elysian development to the Canberra to Mallacoota flight path. AirServices Australia and CASA require advance advice about the project, and monthly updates during construction. The CASA would, as necessary refer the project to the Royal Australian Air Force (RAAF) Aeronautical Information Service (AIS) for inclusion of the turbines in the Tall Structures Database for Australia.

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd

6.5.2 Telecommunications
6.5.2.1 Existing services
The standard SEARs for wind farms require consideration of the possible effect on telecommunications systems. The turbines may cause interference with TV and radio communication services, mobile phone services and point to point microwave radio communication services situated within proximity to the site. Telecommunications services often use the same ridgelines that provide an optimum location for wind turbines.
There is a broadcasting tower is located on Brown Mountain, about 30 km south of the Site. Brown Mountain contains ABC Radio National, ABC News Radio, ABC Classic FM and Triple J radio broadcasting. Brown Mountain previously contained transmission points for analogue television stations; however, this transmission point was decommissioned in the transfer to digital TV. Brown Mountain also contains Point to Point radio communication services for Telstra, NSW Police, NSW Rural Fire Service (RFS), NSW State Emergency Services (SES), NSW OEH and two-way mobile bases for NSW Police, NSW RFS and SES. Local FM stations broadcast from Emerald Hill, near Nimmitabel, about 22 km southwest of the site. Digital television is broadcast to Nimmitabel via the Mt Roberts broadcast site which transmits digital services from ABC, SBS, CBN (Prime), WIN (channel 9) and CTC (Southern Cross Austereo).
6.5.2.2 Potential impacts
Wind farms may cause electromagnetic Interference (EMI) which can reduce signal strength and coverage of mobile phones, radio and aircraft navigation systems. Wind farm development may cause EMI in the following ways:
• near-field effects where the signals within the generator and nacelle cause interference; however, this has been mostly overcome with technological advances in turbine design
• diffraction where a turbine reflects or absorbs a signal • reflection / Scattering where the turbine obstructs the signal and causes interference or distortion (Bacon, 2002).
Exclusion zones (Fresnel zones) would be required around radio communication signals and near-field exclusion zones from radio towers.
Digital TV which has been delivered throughout Australia is not impacted by ghosting associated with wind turbines. There can be some associated reduction to service strength; however, this can be overcome by upgrading dwellings to a directional aerial which is able to disregard refracted signals from turbines. Satellite TV services (pay TV and TV delivered by the VAST service) are not impacted unless the direction of the dish antenna directly aligns with a turbine.
A specialist consultant has been engaged to prepare a report on telecommunications and EMI. This report would be used to inform the EIS.
6.5.3 Health The Standard SEARs for wind energy development require environmental assessment of wind farms to “consider and document any health issues having regard to the latest advice of the National Health and Medical Research Council and identify potential hazards and risks associated with electric and magnetic fields (EMF)”. This section provides a brief review of available literature on the impacts of wind farms on human health in Australia.
6.5.3.1 Potential impacts
The National Health and Medical Research Council (NHMRC) Information Paper: Evidence on Wind Farms and Human Health (2015) undertook a review of evidence on a range of health effects that could potentially arise from living near a wind energy development including noise, shadow flicker and electromagnetic radiation. The NHMRC concluded that “there is no consistent evidence that wind farms cause adverse health effects in humans”; however, also notes that “further high quality, independent research into health outcomes of residents within 1,500 m of wind farms is warranted”.
A summary of the findings of NHMRC (2015) on each of the studied health effects is provided in Table 6-9.

Table 6-9. Wind farms and human health (NHMCR, 2015)
HEALTH EFFECT NHMRC CONCLUSION ELYSIAN WIND FARM
Physical and mental health
Noise associated with wind farms is generally low. There is no direct evidence that exposure to wind farm noise affects physical or mental health outcomes of nearby residents.
Further investigation is recommended for residences within 1500 m of a turbine.
A formal Acoustic Assessment within the EIS will review noise impacts on dwellings located within 1500 m of a turbine, or other buffer distance deemed appropriate based on local topography and monitoring.
Annoyance
Regular exposure to noise may result in annoyance and stress which may increase the occurrence of cardiovascular disease.
However, the NHMRC notes that there is no conclusive evidence of a connection between reported annoyance due to wind farm noise. Reported annoyance due to wind farm noise may be due to pre-existing bias held by observers.
No further action required.
Sleep disturbance
It is well established that chronic sleep disturbance impacts health.
However, the NHMRC notes that there is limited objective evidence linking noise generated by wind turbines to sleep disturbance.
Further investigation is recommended for residences within 1500 m of a turbine.
A formal Acoustic Assessment within the EIS will review noise impacts on dwellings located within 1500 m of a turbine, or other buffer distance deemed appropriate based on local topography and monitoring.
Quality of life NHMRC notes that there is inconsistent evidence of a direct correlation between wind farm noise and quality of life.
No further action required.
Infrasound and low frequency noise
NHMRC notes that there is no direct evidence of infrasound or low frequency noise from wind farms impacting human health outcomes.
No further action required.
Perception of wind farm noise
NHMRC notes that recorded noise levels associated with wind farms tend to be in the range of 30 to 45 dBA at 500 m to 1500 m from a turbine. Beyond 1500 m, recorded noise levels reduce below an intrusive level. Perception of noise beyond 1500 m may be due to the unique properties of noise generated by wind farms such as “whoosh” and “thump” sounds.
A formal Acoustic Assessment within the EIS will review noise impacts on dwellings located within 1500 m of a turbine, or other buffer distance deemed appropriate based on local topography and monitoring.
Shadow flicker
NHMRC notes that there is insufficient evidence of a correlation between shadow flicker generated by wind turbines and poor health outcomes.
The risk of shadow flicker resulting in a seizure in a person with photosensitive epilepsy is considered extremely low.
No further action required.
Electromagnetic Radiation (EMR)
NHMRC concludes that there is no consistent evidence of adverse health outcomes associated with the level of low-frequency EMR that is emitted from wind farms.
No further action required.

6.5.3.2 Recommendations
It is established that repeated exposure to high noise levels may cause stress, annoyance and sleep disturbance. Wind farms generally do not generate high audible noise levels, with measured levels between 30 to 45 dB(A) up to about 1500 m. Wind farms do generate infrasound and low frequency noise however exposure to this type of noise has not been shown to adversely impact health outcomes.
The current NHMRC research concludes that there may be some noise impact on residences within 1500 m of a wind farm which should be further investigated. An Acoustic Consultant will be engaged during the formal EIS process to prepare a detailed noise impact assessment to determine the impact (if any) on sensitive residential receivers within proximity of the proposed development.
6.5.4 Bushfire Bushfires and grassfires are common throughout Australia and are an intrinsic part of Australia’s environment. Similarly, informal seasonal back-burning is widely practiced in the region. Bushfires and grassfires warrant consideration during the proposed development of Elysian, as the proposed wind farm is located near heavily forested areas of the Wadbilliga National Park and the Dangelong Nature Reserve. Although the proposed site comprises largely disturbed land, with a history of logging and selective clearing, there have been fires at the site. Plus, there is strong evidence of recent burning throughout the proposed Elysian development site.
An awareness of the risk of fires is important for any development in rural or regional Australia. Fires area risk to life and property. The NSW bushfire prone land (BFPL) dataset was used to further investigate preliminary bushfire risk at the proposed Elysian development site. The site is largely mapped as Category 1, which is the highest risk for bushfire; however, there are areas of Category 2 (lower risk that Category 1). The national parks areas near the site are identified as bushfire vegetation Category 1. Bushfire risk would need to be considered in the context of the Rural Fires Act (Figure 6-23).
Activities or events that are linked to fire risk for wind energy construction and operation include:
• human error (arson, cigarette butts, etc.) • incidental (backfiring vehicles and machinery, welding, blade strike from earth moving machinery, etc.) • turbine malfunction • dryland lightning strikes • targeted back burning becoming uncontrolled.
Human error is the most likely cause of fire during both the construction or operation phases of the development. Fire may ignite from spark-causing equipment (e.g., grinders, welders, mowers, graders, motor vehicles), other hot works, smoking (discarded cigarette), or spontaneous combustion of wood chip piles or mulch or due to the inappropriate storage of combustible materials such as chemicals.
There is a potential for fire to occur associated with the project infrastructure including the powerlines, substation and the wind turbines. For example, although unlikely, the nacelle or other housing may ignite because of an electrical or mechanical fault. Fire within a nacelle could spread during adverse weather conditions. Due to the height of the nacelle, physically extinguishing the fire may be difficult. Local NSW RFS brigades may require additional training and specialised equipment to fight a wind turbine fire. A fire originating within the proposed development site could also spread beyond the site boundaries.
Given the recent history of bushfires at the proposed Elysian development site, bushfires may be a threat to the project. The host landowners all currently implement bushfire risk reduction practices, including clearing of overgrown access tracks, maintaining protection zones around infrastructure, and maintenance of bushfire ‘fuel’ loads. Identification of bushfire risks, consequences and likelihood of occurrence is addressed in the Snowy Monaro Bush Fire Risk Management Plan (SMBFMC, 2009), which should be referenced during subsequent design and environmental assessment. A detailed assessment of bushfire risk and required asset protection zones would be undertaken during development of the EIS.

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd

6.5.5 Blade throw and blade glint
Turbine rotor failure may cause blade throw, which is required to be assessed in the SEARs for wind farms. Turbine rotor failure may result in the partial or complete detachment of a turbine blade. The likelihood of a blade throw incident is low; however, this impact is discussed for completeness.
Blade glint is the direct reflection of the sun on wind turbine infrastructure and results from the reflectivity of the white coloured tower, nacelle and blade components of the turbine. Most manufacturers of wind turbine infrastructure treat the turbine with materials with low reflectivity coating to minimise glint and potential nuisance. EWF understands that treating the blades in such a manner is ordinarily seen as an acceptable method in the approval of wind energy developments in NSW.
6.5.5.1 Blade throw
The likely distance or range of blade throw is dependent on the release velocity and turbine tip speed. A variety of competing techniques are used to calculate the range of blade throw and the appropriate distances turbines should be setback from residential properties (Rogers et al., 2012; Larwood, 2005). There have been limited incidences of blade throw or failure in modern wind turbine infrastructure. Academic studies suggest the turbine failure rate is in the range of 1 in 1,000 to 1 in 10,000 turbines (Larwood, 2005). Based on this probability, the chances of a blade throw incident at the proposed Elysian development site are considered very low.
Historically, appropriate setbacks have been calculated at a rate of 1.25 to 3 times the overall turbine height; however, as modern turbines offer higher reliability and reduced potential of blade throw, there is considerable evidence now to suggest that the concept of blade throw, and associated setback requirements be revisited (Larwood, 2005; Rogers et al., 2011). To date, there are no Australian guidelines for blade throw distances or calculation. Blade throw incidents studied by Larwood resulted in a maximum throw distance of approximately 100 m for a whole modern blade, and up to 500 m for blade fragments.
EWF would consider setback rates in its final wind farm planning. At present, the minimum distance between a turbine and a dwelling is 3.61 times the overall proposed turbine height. This is compliant with the setback rates calculated in the literature. All dwellings have a minimum 500 m setback distance from turbines; therefore, we consider the risk of blade throw to be low and able to be overcome by planning.
Because of recent engineering development in wind farm technology, the likelihood of blade throw has been significantly reduced. The location of the proposed site and separation of infrastructure from residential properties has reduce risk, and further analysis of this potential impact or development of management methods is considered unnecessary at this time.
6.5.5.2 Blade glint
There is no specific legislation in NSW regarding blade glint; however, the following documents provide some guidance to the assessment of glint in wind farm proposals:
• the VIA Bulletin states:
“the direct reflection of the sun from the wind turbine structure (glint) is to be minimised through appropriate turbine treatments (such as the use of low sheen and matt finishes).”
• the now repealed, draft NSW Planning Guidelines: Wind farms (2011), similarly states:
“The impact of ‘blade glint’ from wind turbines on neighbours’ houses within 2 km of a proposed wind turbine should be assessed. Blade glint refers to the regular reflection of sun off rotating wind turbine blades. Blades should be finished with a low reflectivity surface treatment to ensure that glint is minimised.”
A 2 km buffer, as suggested in the now repealed 2011 guidelines, has been adopted as a reasonable physical extent for the consideration of blade glint.
As suggested in the relevant assessment guidelines, blade glint is minimised by use of low-reflective finishes on all turbine infrastructure. The location of turbine infrastructure, including the distance from residences and roads, is also an important management method. The proposed turbines are located a minimum of 500 m from major roads, including Tuross Road and 940 m from the nearest non-stakeholder dwelling.

6.6 Aboriginal Heritage The Aboriginal heritage assessment comprised:
• a search of the NSW Office of Environment and Heritage (OEH) Aboriginal Heritage Management System (AHIMS) database to determine if there had been any archaeological material recorded in the subject land
• a landscape assessment to determine if there are landforms with a high potential to contain Aboriginal objects and to what extent they coincide with proposed tower locations
• preliminary impact assessment and recommendations for further work required.
6.6.1 Applicable legislation and literature review
6.6.1.1 The National Parks and Wildlife Act 1974 (NSW)
In NSW, Aboriginal heritage objects and places are protected mainly by the National Parks and Wildlife Act 1974, which contains provisions making it illegal to harm Aboriginal objects and Aboriginal places without appropriate defence or permission. The Act is administered by the NSW Office of Environment and Heritage (OEH). Under definitions provided in the Act:
• Aboriginal object means any deposit, object or material evidence (not being a handicraft made for sale) relating to the Aboriginal habitation of the area that comprises New South Wales, being habitation before or concurrent with (or both) the occupation of that area by persons of non- Aboriginal extraction and includes Aboriginal remains
• Aboriginal place means any place declared to be an Aboriginal place under section 84.
If Aboriginal Objects are harmed, there are two levels of offence that Individuals or corporations may be faced with. Knowingly or deliberately harming or desecrating Aboriginal places/objects is the higher of the two levels. Lower level offences are known as ‘strict liability’ offences, that is to say they are offences regardless of whether or not the offender knew they were harming an Aboriginal object or desecrating an Aboriginal place. A person or corporation may have a defence against such prosecution where they have:
• an Aboriginal Heritage Impact Permit (AHIP) authorising the harm (s.87(1)) • exercised due diligence to establish Aboriginal objects will not be harmed (s.87(2)).
Due diligence may be demonstrated by following requirements described in the National Parks and Wildlife Regulation 2009 (the Regulation) or a code of practice adopted or prescribed by the NPW Regulation (s.87(3)).
6.6.1.2 The Due Diligence Code of Practice for the Protection of Aboriginal Objects in NSW 2010
The Due Diligence Code of Practice for the Protection of Aboriginal Objects in New South Wales (the Code) describes the process that must be followed to demonstrate due diligence in assessing potential harm to Aboriginal objects by a proposed development or action. The Due Diligence Code sets out steps required to assess whether or not proposed activities may impact Aboriginal objects. These are:
• step 1. Will the activity disturb the ground surface? • step 2a. Search the AHIMS database and use any other sources of information of which you are already aware • step 2b. Is the Activity in an area or areas where landscape features indicate the presence of Aboriginal objects • step 3. Can any harm or the activity itself be avoided? • step 4. Desktop assessment and visual inspection • step 5. Further investigations and impact assessment.
Addressing these questions will determine whether or not Due Diligence obligations for the protection of Aboriginal objects are satisfied. If they are not, further approval (an AHIP) under the NPW Act is required, and this may be a recommendation of the Due Diligence study.
6.6.2 Existing environment
6.6.2.1 Ethnohistorical
Ethnohistorical records are documentary pieces of evidence that record observations of Aboriginal people by early European explorers and settlers. They are useful in the reconstruction of the picture of Aboriginal life before the European settlement. Like all historical records they fall into different categories of direct observation and include, for example:

PRELIMINARY ENVIRONMENTAL ASSESSMENT Elysian Wind Farm Prepared for Elysian WF Pty Ltd
31 March 2020
• journals from explorers and early European occupants of the area – including surveyors, and government officials (direct and contemporary observations recorded close to the time of the event)
• later reminiscences by long-time residents or travellers; • secondary documentation by writers who did not actually observe events or people but were told about them by
people who did observe events.
In research and heritage management studies ethnohistorical records are examined with two main purposes. The first, and most practically applied, is to inform researchers of the range of material remains that could reasonably be expected to occur in any given study area, and where that material might occur. So, for example, where an early observer describes how Aboriginal people in the local area made fine canoes out of sheets of bark cut with stone hatchets, one might reasonably include scarred trees to the types of archaeological site that could be expected in the area and realise that ground stone hatchet heads might occur in the artefact assemblage. The second main use of ethnohistorical records in such studies is to add a human element to the research and analysis of archaeological materials and places.
While ethnohistorical records are a valuable resource in the reconstruction of a picture of pre- European Aboriginal life and material culture, there are limitations to their use. One of the primary limitations is that by their nature they are the sporadic records of untrained observers of varying quality and reliability, as opposed to systematic studies. Further, they are products of their times and, like any observation or historical description, they can be value laden. As a further caution it is to be noted that changes to traditional Aboriginal society and life ways in south east Australia were rapid after the arrival of Europeans in 1788, so it is unlikely that the earliest recordings of Aboriginal people in a given area were of a people completely unchanged by European influence - either through being ravaged by European disease or having contact with European material possessions. Diseases (notably small pox and influenza) were carried out from Sydney by Aboriginal people and infected the wider Aboriginal population prior to their contact with Europeans.
For the purposes of this study, ethnohistorical records are informative in terms of predicting and explaining the sorts of sites that might occur in the study area, analysing archaeological material that might be found, and in assessing significance.
The study area is situated in a territory generally acknowledged as Ngarigo country (Howitt 1904, Tindale 1974, Flood 1980). Documentary evidence regarding Aboriginal people is relatively sparse, surprisingly so, given the acknowledgment that Aboriginal people were closely associated with the earlier phases of European exploration and settlement (English 1985: 21). It has been suggested that the scarcity of references to Aboriginal people in explorer’s journals is the result of deliberate avoidance of them by Aboriginal people (Lea-Scarlett 1968).
Some material culture is described in the early documentation. The observed tools and possessions included spears (barbed and unbarbed), spear throwers, clubs, shields, boomerangs, stone axes, yam sticks, bark vessels, canoes, apparel made from skins (possum and kangaroo), shell and stone scrapers, bone needles, and bark huts (Wright 1923, Helms 1895, Bennett 1834, all in Flood 1980:49-60). Stone axes in particular were said to be highly prized with men rarely going anywhere without them tucked into a fur belt around the waist (Graham 1863). Bark was a material in ubiquitous use for a number of purposes, primarily shelter, containers and canoes. In the early to mid-1830’s Edward John Eyre purchased a land grant that he called ‘Woodlands’ which bounded on the Molonglo River between Queanbeyan and Captains Flat. He records Aboriginal people being employed to cut sheets of bark to assist in the construction of a shearing area. He records:
The bark was cut from the box or stringy bark trees by the blacks who are very skilful and expeditious in doing it. Having selected a suitable tree, the black fellow begins by cutting a ring round the tree thro’ the bark to the wood, just where the lower end of the sheet of bark is intended to be. He next cuts with his tomahawk little steps in the bark about half an inch deep, about two feet apart, alternately on the right and left, into which he puts his great toe as he mounts from one to the other, pressing his feet and legs against the trunk…. For tho’ he uses his hands in catching hold of the tree from time to time as he rises, yet he can stand on these little notches alone and keep both hands free to use in whatever he may be about. In smaller sized trees that he can grasp with his arms he will run up as rapidly as possible without cutting steps or aid of any kind. Having ascended to the requisite height he again cuts a ring around the tree where the top of the sheet of bark is to be and then, gradually descending, makes a perpendicular or longitudinal cut straight down from the upper ring to the lower one. With small pointed sticks he again mounts and inserting them on each side of the perpendicular cut between the bark and the wood, he gradually loosens the former from the latter until at last he gets it stripped off in one unbroken piece forming, when stretched out flat, a sheet from six to twelve feet square, according to the size of the tree. To prevent the bark from cracking when being thus stretched out it is heated inside with fire, just as a cooper heats a cask to make the staves bend as he wishes. The same means are used to bend the

bark into shape when required for a canoe…I have often seen canoes made of a single piece of bark capable of holding six or eight people. Generally, these were cut from large river gum trees…When dry these sheets of bark retain their flat shape - are from an inch to an inch and a half thick – quite impervious to any rain and, of course, most useful in the construction of temporary dwellings, sheds or other buildings. A single sheet properly stretched out and propped up with sticks forms and admirable shelter for the night from any rain, and is constructed by a black fellow, where the proper trees are to be found, in a very few minutes (Eyre 1984:55-56).
Aboriginal food items recorded in the ethnohistoric literature include possum, bandicoot, snakes, various macropods, wombats, emus, brolgas and other birds, lizards, 'native cats', fish, yabbies, mussels, Bogong moths, yams, berries and grass seeds. (Bennett 1834, Bluett 1954). In addition, the author of this report has personally observed and gathered large clusters of very large field mushrooms in the Kybeyan area, which would have easily been a source of seasonal abundance.
The ceremonial and ritual aspects of the lives of local Aboriginal people were rich and intricate. Class and totem systems are recorded for Aboriginal people of the region (Howitt 1904:101-102). Men’s initiation ceremonies, variously called the Kuringal or Bunan involved tooth evulsion and ceremonies inside earthen mounds. (Howitt 1904: 563-565).
Local burial customs included binding of the body into a foetal position and interment with all the deceased’s weapons and implements. Howitt records “spears and nets were included; even in one case a canoe was cut into pieces so that it could be put in the grave. Everything belonging to a dead person was put out of sight” (Howitt 1904:461-462). In the region burials have also been recorded in caves and hollow trees (White and Cane 1986:44). Clark recorded oral history from near Boorowa suggesting that Aboriginal people had been buried at the base, and at the top of a hill, the latter of which occurred between large broken rocks. He specifically notes “from the top of the hill one has a commanding view of the surrounding country side” (Clark 1977:16). This description has analogies to Wright’s description of the burial of Hon Yong (Onyong) who wrote “His grave was on top of a rocky hill…A tunnel about six feet long was excavated and his body was inserted, with his spears (broken in half), his shield, nulla, boomerang, tomahawk, possum rug and other effects (Wright 1923:57).
The dislocation of Aboriginal people in the face of the European settlement appears to have been rapid and traumatic. Smallpox was observed at Yass in 1844, and it is highly likely that the disease had reached the Southern Tablelands at a somewhat earlier date, although possibly not before 1830. Other diseases against which the Aborigines had no immunity included measles and influenza (Flood 1980: 32). In a little over fifty years after the first European incursion into the area, the fully traditional way of life had disintegrated. (Andrews 1979).
While the purely traditional way of life passed, the descendants of those people retain their Aboriginal tribal identity. They are genuinely concerned about the preservation of their cultural heritage.
The ethnohistorical record provides the following information that informs the preparation of this study.
1. the local area contains a range of resources that are recorded in the ethnographic record 2. the last phase of traditional Aboriginal life ceased in approximately the mid 1880’s, so sites like stone artefact
scatters date to a time before this 3. bark was used for many traditional purposes; the occurrence of scarred trees is a possibility although the
widespread clearing and logging would have compromised the potential for large numbers of scarred trees to be found
4. given the traditional and semi-traditional activities that were undertaken in the area into the late 19th century, the occurrence of European materials as part of the Aboriginal archaeology is a possibility (for example, glass or ceramic flaked artefacts).
6.6.2.2 Archaeological
The broader region of south east NSW has been occupied by Aboriginal people for at least 21,000 years. Human occupation at Birragai rock shelter has been dated to ~21,000 Before Present (BP) (Flood et al 1987), Burrill Lake rock shelter near Ulladulla has been dated to ~20,000BP (Lampert 1971) and Bulee Brook 2 in the south coast hinterland has been dated to ~19,000BP (Boot 1996a & b, 2002), these three sites all providing a reasonably consistent picture of the time human occupation of the region becomes archaeologically visible.
Flood’s pioneering archaeological work in the NSW high country emphasised the potentially seasonal nature of occupation, concentrating on ethnohistorical accounts of Bogong moth collection (Flood 1980). She suggested that Ngarigo people occupied the lower hinterland during winter and moved into the high country in summer to collect the moths. Despite arguments refuting the importance of Bogong moths as a seasonal staple (Chapman 1977, Bowdler

1981) or that it was a resource that fostered social cohesion and exchange rather than being a staple food (Kamminga et al 1989), seasonal use of the highlands continues to be the main interpretation of local Aboriginal occupation.
Heffernan and Boot conducted a wide ranging study of the South East Forests (Heffernan and Boot 2000). In a survey transect along Kybeyan Road they recorded eight open artefact scatters and five isolated finds. Dearling (2004) undertook a study of a number of nature reserves and state conservation areas in environmental/ topographic locations similar to the present study area. Among the areas he inspected the following are particularly relevant:
• Kybeyan Nature Reserve: three open artefact scatters and two isolated artefacts (14 artefacts in total) all within a large grassy clearing, crossed by drainage lines, soaks, and minor wetlands. Seven stone materials were recorded, although the small number of artefacts overall makes the sample difficult to draw extensive conclusions. The materials were chert (28.6%), quartz (28.6%), silcrete (14.3%2), indurated mudstone, chalcedony, volcanic, and unknown (each 7.1%).
• Kybeyan SCA: One quartzite broken flake was recorded. • Dangelong Nature Reserve/Mowles Creek: six open artefact scatters and three isolated (116 artefacts in total).
Most were found close to the junction of the Numeralla River and Granny’s Flat Creek. The largest site at Mowles Creek contained 44 artefacts. Eight stone materials were recorded- silcrete (71%), quartz (14.5), chert (7.3), volcanic (3.6%), and Indurated mudstone (3.6%).
• Coornatha Nature Reserve: This study area contained one artefact scatter and one isolated artefact (total five artefacts). The isolated find was located in the area of basalt in the south east corner of the Nature Reserve. Two stone materials were recorded, Chert (60%) and Quartz (40%).
At the ‘Warratah’ property at Kybeyan Dearling (2007) recorded seven Aboriginal archaeological sites, with an overall a total of 53 stone artefacts. Quartz was the dominant stone material, with chalcedony, chert, silcrete andvolcanic artefacts also recorded (Dearling 2007:29). These sites were associated with low gradient terrain, either spur crests or valley floors, with raised level terrain in proximity to water exhibiting the greatest artefact densities (Dearling 2007:27-28). In a re-examination of part of this study area, Williams (2017) relocated Dearling’s site WK-2 recording 31 flaked stone artefacts and further recorded a new site ‘WK-9’, an artefact scatter with 21 artefacts. Both of these artefact clusters were found on locally raised spurs in association with Greens Creek, a small permanent watercourse.
In 2005 Dibden undertook an assessment of a proposed fence alignment at ‘Lone pine’, in Wadbilliga National Park, ~7km south of the present study area. The fence was ~5.5km in length, traversing a range of landforms and vegetation. Seven archaeological sites were recorded mainly in association with spur crests and drainage depression topographic features of low gradient. One major site consisted of more than 80 artefacts over a 200m x 10m area on a knoll and spur crest. Materials recorded included silcrete, quartz, quartzite, volcanic and chert (Dibden 2005:20).
Dibden (2009) undertook an assessment of the Boco Rock Wind Farm west of Nimmitabel, recording Aboriginal stone artefacts at 56 locations. Elevated, relatively level ground close to the Maclaughlin River was found to be the most archaeologically sensitive terrain. Higher terrain such as plateau and high ridge lines exhibited stone artefacts, but at a far reduced density. A total of 237 artefacts were recorded, with quartz and silcrete being the dominant stone materials (Dibden 2009: Appendix 1).
Dibden undertook an archaeological assessment of proposed maintenance work on Wadbilliga Road in Wadbilliga National Park (Dibden 2010). The project assessed the potential impact of widening the existing road by ~1.5m over a total of 5.5km. The project required the installation of nine culverts and removal of 16 trees (Dibden 2010: 3). The study recorded Aboriginal cultural material in the form of stone artefacts at five locations, some of which were revisits to sites recorded some years previously. An extensive scatter of cultural material was located across the area of 2 previously recorded sites (Dibden 2010: 35). The scatter was recorded as occurring over 690m on the east side of the Wadbilliga River, with an earlier recording by Boot noting 1185 artefacts (Dibden 2010:35). The remaining four locations were isolated artefacts, and these objects were found in disturbed contexts and topographic locations not conducive to camp site locations.
In 2015 Dibden undertook an assessment of proposed work on the Kybeyan Radio Tower and Tuross Falls Road in Wadbilliga National Park (Dibden 2015). The purpose of the project was to assess sections of Tuross Falls Road where Aboriginal objects were known to occur, in addition to the small area of proposed disturbance at the Kybeyan Radio tower (Dibden 2015:35). Of the seven site locations investigated, stone artefacts were observed at three, with no objects found at four previously recorded locations. The Kybeyan radio tower location exhibited no archaeological material.
CHMA (2016) undertook a preliminary assessment of a proposed wind farm ~25km south of the present study area. Engaged to provide a preliminary heritage assessment of the wind farm footprint as it was then designed, the sample

survey recorded 13 previously unrecorded sites, termed GH1-GH13 inclusive, and five Potential Archaeological Deposits (PADs) (GH PAD1-5). Of the sites recorded, four were open artefact scatters and nine were open artefact scatters with associated PADs. Approximately 160 stone artefacts were observed (CHMA 2016:40-41), noting that the preliminary nature of the study precluded detailed recording and precise counts.
The study found that where good visibility coincided with broad, open flat crests or saddles within a reasonable distances of water sources cultural material was found, suggesting a widespread scatter of material over those landforms (CHMA 2016:39). A subsequent more detailed archaeological survey was undertaken in 2017 which identified an additional 22 sites including scatters of artefacts, isolated artefacts, potential archaeological deposits scarred trees and a potential quarry (Williams 2018:16-24). 730 stone artefacts were recorded with nine stone materials represented and sixteen technological categories of artefact recorded. Quartz and silcrete artefacts were recorded in approximately equal proportions although there were twice the number of quartz cores and core fragments as there were of silcrete. This suggests that quartz artefacts were created from more readily available and/or smaller nuclei and that silcrete was a more curated material. It was concluded that the archaeological evidence recorded suggested regular use of the study area as a transitory landscape (Williams 2018:31). Evidence of Aboriginal occupation was widespread in locations that offered level to gently sloping topography, but archaeological evidence in the form of artefact scatters also occurred in areas of steeper gradient close to permanent water sources.
The majority of archaeological studies in the area have overwhelmingly recorded scatters of stone artefacts, but other types of archaeological sites have been recorded on the Monaro. In 1991 the remains of two Aboriginal people were discovered eroding out of the bank of Rock Flat Creek at Bunyan ~10km north of Cooma. Despite heavy disturbance it was intimated the people were buried side by side at the same time. Grave goods were found with the human remains, including red ochre, two pebble hammer/anvil stones, five bone points made of kangaroo fibulae eight macropod mandibular rami and 327 pierced kangaroo teeth – all upper incisors pierced to allow them to be strung (Feary 1996).
In 1988 Comber undertook an examination of four quarry/reduction sites between Bredbo and Cooma (Comber 1988). Two of the quarries (A and B) are tabular chert, one (C) was basaltic andesite and one (D) was dacite.
6.6.2.3 AHIMS
A search of the OEH AHIMS register was undertaken on 28/03/2019, over a ~1,295 km2 area centred approximately on the proposed extent of turbines. Within this boundary there were 107 previously recorded sites, only one of which occur within 1 km of a proposed turbine location. The nearest known site to a proposed turbine is site 62-2-0412 (WK-7) which is ~300 m east north east of proposed turbine 30. The locations of these previously recorded sites are illustrated in Figure 6-24.

6.6.2.4 Artefact scatters
These are a very common site type and consist of stone artefacts found scattered on the ground surface and are often referred to as an open camp site. In most archaeological contexts, an artefact scatter has been deflated by erosion, or it more typically involves a sub-surface deposit of varying depth. Artefact scatters may represent :
• the evidence of camp sites, where everyday activities such as habitation, preparation and consumption of food and storage of tools have occurred
• hunting or gathering events • other events spatially separated from a camp site (e.g. tool production or maintenance) • transitory movement through the landscape.
The detection of artefact scatters depends upon conditions of surface visibility and ground disturbance and post depositional change through either sediment accumulation or surface erosion. Vegetation cover and deposition of sediments generally obscures artefact scatter sites and prevents their detection during surface surveys. High levels of ground disturbance can also obscure or remove evidence of a site. Isolated finds are single artefacts.
They may be representative of simple, singular discards or may be all that is visible within a site, with other material either obscured from view or buried beneath the surface. The ability to observe surface archaeological material at a site will change with altered environmental conditions, therefore visits to the same site at different times almost always result different observations. Artefact scatters might occur in any area with low gradient but will be most dense and easily detectable on level, raised, well drained locations close to water sources or other resource zones such as wetlands.
6.6.2.5 Scarred trees
Scarred trees are those from which the bark has been removed for the manufacture of containers, shields or canoes. Small scars may also represent toe-holds cut into a tree to enable climbing. They are a common site type in the river flood plain corridors. It would be unlikely that scars in this location would be the result of canoe manufacture, so those that are the result of making containers or shelters would be more likely. Scarred trees might occur at any location where mature native trees remain.
6.6.2.6 Burials
Human burials have only rarely been discovered in the region, but those discovered have been found in deeper soil of creek margins (Feary 1996). It is unlikely that any surface survey would detect human burials, and the turbine locations are on high points that will in all likelihood have thin soil profiles, but as the area is drained by several creeks which may require crossing by connecting tracks and/or power cables it is possible that this site type may occur in land subject to disturbance by the establishment of the development.
6.6.2.7 Stone quarries
Hiscock and Mitchell (1993: 19-23, 32) have defined an Aboriginal quarry as being the location of an exploited stone source. This definition was adopted by them as it took in the widest possible range of sites related to stone procurement strategies. As well as including areas exhibiting visible evidence of exploitation, this definition can be extended to areas where procurement techniques have left little or no evidence of activity. Aboriginal stone quarries may range from large, well organised sites and cover may hectares (e.g. the Mount William greenstone quarries, McBryde 1984) to simply locations of cobbles or pebbles which can be easily collected as required (cf. Gould 1977:162-8, Jones and White 1988:57-8,). The underlying geology of the subject area is not one where an Aboriginal quarry would be expected, but stone hatchet quarries are a possibility.
6.6.2.8 Potential archaeological deposits (PADs)
PADs may be defined using topographic and/other environmental variables where it is considered highly likely that archaeological material may occur under the ground, but surface visibility is poor.
6.6.3 Potential impacts The majority of proposed turbine locations to coincide with ridge line features such as crests, knolls and plateaux. Previous archaeological studies in the region identify these elements as having higher concentrations of archaeological material than surrounding sloping topography and in fact in hilly to undulating terrain serve to focus human activity in smaller areas of low gradient. This archaeological material is in the main scatters of stone artefacts of varying density. Where areas of low gradient coincide with watercourses archaeological occurrences become more frequent and denser. As these proposed turbines occur at high points in the landscape their archaeological potential is lessened by distance

to fresh water, but prior studies have also shown that water sources can occur at higher points in the landscape, particularly on plateau type elements (cf. Williams 2018:19).
6.6.4 Recommendations The requirements of efficient wind farm establishment are such that the locations of proposed turbines often coincide with topographic elements that have higher archaeological potential, likewise access roads often follow crest and/or level topography for ease of construction. The suite of proposed locations examined in this study fits that coincident model in large measure, and as such the majority of proposed turbine locations should be subject to a detailed field inspection prior to development occurring. This inspection should take the form of an Aboriginal Cultural Heritage Assessment, following the requisite guidelines and standards issues by the NSW Office of Heritage and Environment.
Prior to such inspection the proponent should examine the design of the proposed development with reference to more detailed topographic information (for example, LiDAR generated contour maps) in order to determine if any proposed turbine locations and or access tracks are now on, or are able to be moved to, topography with a slope of >70, as this would place any such turbine / compound in zones of lower archaeological sensitivity.
The Preliminary Aboriginal Heritage Assessment Report is provided in Appendix E.

6.7 Water and soils 6.7.1 Water The proposed development site sits predominately along the ridgelines and therefore, the is limited potential for flooding. The access roads will, however, cross many minor creek alignments near the headwaters of those systems. As the proposed Elysian Wind Farm project site is in a woodland environment, organic material including tree branches are likely to be mobilised during rainfall events.
The nearest rain gauge operated by the Bureau of Meteorology is at Nimmitabel (site 070067; data from 1894 to 2016), about 21 km from the proposed development site at an elevation of 1100 m, which is similar in elevation to many areas of the proposed site. Average annual rainfall at Nimmitabel is 694 mm. Mean monthly rainfall ranges from 45.7 mm in August to 68.7 mm in January (Table 6-10). Mean monthly data indicates that rainfall is relatively consistent throughout the year, with high rainfall in winter and summer months, and less in spring and autumn.

There are several ephemeral creeks and streams that transect the proposed Elysian development site, and several semi-permanent informal dams, along Tuross Road for example (Figure 6-25). Design of any crossings would need to consider potential blockages and be able to withstand overtopping without scouring across the road surface or downstream embankment.
Creek crossings will need to ensure they have capacity for significant events without creating or exacerbating erosion potential. Culvert designs will need to ensure the downstream apron is as wide and flat as possible with long-term stable scour protection to reduce concentrated flows and scour velocities. There is also mapped key fish habitat (KFH) within the site which would need to be considered in detail during the EIS.
There are no registered groundwater bores located within the proposed Elysian development site (WaterNSW search date: 10 January 2019); however, given the history of grazing at the site, it is likely that unregistered groundwater bores occur within the proposal boundary. This would be assessed during the EIS.

6.7.2 Soils
Detailed geotechnical investigations have not yet been conducted, and therefore could not inform the PEA. However, a desktop assessment was used to interrogate soils and geology for the PEA.
The proposed Elysian development site is situated on Yalgatta Granodiorite geological unit. Soils are of the Lower Dovonian around, 400 million years old. Crusts are shallow and generally unfractionated to weakly fractionated (NSW Seamless Geology). There is no risk for Acid Sulfate Soils at the proposed Elysian development site. The overall land soil capability is rated as ‘Severely limited’ (Figure 6-26).

There are several soil landscapes within the proposal development area. These landscapes are associated with several characteristics and limitations, which are outlined in Table 6-11. These landscapes are generally used for sheep and beef production and demonstrate variable erodibility, waterlogging and fertility.
Based on the details of the proposed development known at the time of producing this PEA, these soil constraints appear to be manageable. Factors affecting erosion during construction and access in wet conditions (particularly along informal and/or unsealed roads) and means to control erosion during construction and operation will need to be considered during the design stage and during the process of refining the turbine locations.

6.7.2.1 Potential impacts and recommendations
Investigations undertaken to inform this PEA suggest that the potential for site contamination is low; however, it is still suggested the following management methods be considered:
• ACM removed and disposed by an adequately licenced contractor • baseline assessment of water quality of the creeks within the proposed development site to allow any changes to
water quality be monitored and appropriately addressed • development and implementation of a Construction and Environmental Management Plan (CEMP) including
measures to minimise runoff and sedimentation of creeks and streams within the proposed development site • CEMP would include measures to minimise soil disturbance and ensure polluted and sediment laden water is not
discharged into downstream waterways • avoid clearing vegetation on areas likely to erode and contribute to degrading water quality, where possible • restrict construction vehicles to access roads where possible to reduce disturbance of soil which may increase the
sediment load of runoff • undertake water quality monitoring prior to commencing works to provide a baseline for monitoring of the
proposed development site during construction and operation. Water quality testing should include total

suspended solids, total phosphorus, total nitrogen, pH, electrical conductivity, temperature, enterococci, and turbidity -especially during / after rainfall events
• water quantity assessment to confirm suitability for abstraction during construction, if this option is maintained • sealing of relevant access roads, or sheeting of roads with suitably sized gravel to avoid erosion in susceptible areas • stabilise and rehabilitate / revegetate disturbed areas as soon as practicable • installation of rainwater collection tanks for use by the proposed development site office • development of an unexpected finds protocol • preparation of a Hazardous Materials Management Plan prior to the commencement of construction on the
proposed development site detailing storage arrangements for fuels, oils and other substances • placement of liquid storage areas away from waterways and drainage channels, and within bunded areas to
minimise pollution incidents resulting from spills.
We do not predict that water management issues would adversely constrain the feasibility of the proposed Elysian development. Existing creeks within the site present an opportunity to use a locally available resource in construction to eliminate the need to transport water to the site. EWF would obtain all required licences to use water for construction purposes under separate application.

6.8 Waste 6.8.1 Waste streams There are no registered contaminated sites from the National Pollutant Inventory (NPI) within the proposed Elysian development area, nor are there any records of naturally occurring asbestos. There is the potential for the site to have buried rubbish and informal landfills from past agricultural practices, which can contain contaminates such as herbicides, disused batteries and heavy metals. If these are encountered during construction without appropriate management measures in place, they may present health issues.
While waste generated by the ongoing operation of the proposed development would be minimal, we anticipate that construction waste would need to be appropriately managed to minimise safety, fire and environmental hazards (Table 6-12).
Table 6-12. Indicative waste streams
WASTE TYPE GENERATED BY STRATEGY FOR REUSE OR DISPOSAL
Excavated material Excavating for footings, access roads and levelling for substations
Reuse for backfilling and road construction if possible.
Cleared vegetation Clearing and trimming of vegetation Mulching and reuse on-site
Timber Formwork, packaging Reuse where possible or dispose of in a Council-approved landfill
Excess concrete Inefficient ordering / on-site batching
Recycle or dispose of in a Council-approved landfill
Scrap metal Reinforcement and cut-off Collect and recycle
Waste oil, lubricants Maintenance of turbines Dispose through commercial chemical contractor
Office waste Site office Reuse on-site, recycle through contractor
Sanitary waste systems Temporary toilet facilities (e.g. Port-a-loo) Managed through contactor
General rubbish Construction workers Sorted for recycling and/or disposed of in a Council-approved landfill, Contractor to collect
6.8.2 Potential impacts and recommendations Given the isolated nature of the proposed Elysian development site, appropriate management, storage and disposal of waste during both construction and operation of the wind farm is an important consideration. To minimise waste generation on-site, contractors and employees would be encouraged to efficiently order construction and office waste, reuse and recycle waste where possible and appropriately dispose of waste which is unable to be reused on-site by way of regular commercial collection by licenced contractors.
Waste generated by construction and operation of the proposed development would be minimal and that the site can be appropriately managed to prioritise recycling and reuse of materials where possible and minimise impact on landfill. The proposed development is expected to generate minimal waste during operation. However, waste will be an important consideration once the Elysian development matures and must be decommissioned.
A detailed Waste Management Plan (WMP) would be completed as part of the EIS.

6.9 Cumulative impacts The Wind Energy Guideline requires consideration of the cumulative impact the proposed development and any other existing constructed or approved wind farms may have on the local area in relation to visual amenity, noise, biodiversity and traffic.
The significant +50 km of separation between the proposed Elysian development and the closest turbine in the Boco Rock wind farm would minimise cumulative visual impact. Boco Rock Wind Farm is not visible, even in good weather, from high points on the proposed Elysian development site. Topography and vegetation between the sites provide interruption of the viewshed.
The VIA Bulletin requires the establishment of a ‘visibility distance zone’ - a range of distance zones from selected viewpoints where turbines and ancillary infrastructure would be visible. It is anticipated that the VIA in the EIS would not need to assess any view corridors in the two sites, and from viewpoints further afield looking back at the two sites, as the wind farm sites are not within 8 km of each other.
It is anticipated that the proposed Elysian development would have the following beneficial impacts on the local and regional area:
• contribution to the local economy through creating jobs for contractors during construction and ongoing employment during operation
• demand for secondary services in the local area during construction • securing additional renewable energy sources to meet electricity demand in the wider community.
6.9.1 Management We do not anticipate that cumulative impacts associated with the introduction of a second wind farm to the area would generate the need for specific management practices.
6.9.2 Predicted Outcome We predict that the separation between the proposed Elysian development and Boco Rock wind farm is enough to ensure that there are no cumulative effects arising within the local environment. As such, EWF does not anticipate further consideration of this impact is required.
Figure 6-27 shows the distance and terrain between the proposed Elysian development and Boco Rock wind farm, which is the closest constructed or approved existing wind farm to the proposed development site, located more than 50 km to the south-west. As Boco Rock Wind Farm is located more than 8 km away from the proposed development site, a detailed cumulative impact assessment including this wind farm is not considered warranted; however, this will be assessed further in the EIS.

8 Conclusion The proposed Elysian wind energy development presents an opportunity to increase renewable energy output in NSW. As discussed in this PEA, minimising adverse impacts on the local community has, and will continue to be, a key consideration in the design and layout of the proposed Elysian development turbine layout. Design development to date has sought to minimise potential adverse impacts on nearby national parks and reserves, considered the location of turbines and roads to minimise potential adverse impacts on the environment, threatened species and their habitats, and appropriate location of turbine infrastructure to minimise the visual intrusiveness of the proposed wind farm on residential and from key public viewpoints.
EWF is committed to minimising potential long term economic, visual and environmental adverse impacts on the local area and changes that may be required in consultation with state agencies and the DP&E would continue to be undertaken. EWF is also committed to continue to work with residents and preliminary consultation with the community has shown support for the project.
This proposed site is favourable for the development of a wind farm with:
• consistent and adequate wind speed • proximity to high voltage transmission lines and uncomplicated connection to the existing electricity grid • isolation from residential properties and high population densities • proximity to natural water sources • ready access to existing highway infrastructure for construction, turbine delivery and emergency access • limited clearing required of natural wooded vegetation.
We respectfully request that the detailed discussion presented in this document be considered in the preparation of site-specific SEARs.

Appendix B Communications Log
Elysian Wind Farm community protocol: Since 2017 the then proponents of the wind farm development have been in dialogue with neighboring properties regarding the development and participation. A number of the neighboring and surrounding properties are not permanently habited as they are weekenders, bush block, holiday units or managed/owned by farming conglomerates. Consequently, it has not been possible to contact a number of residents at the property as they were not present when representatives visited, gates were locked and contact details not traceable by ordinary means. Snowy Monaro Council has sent a notice and news letter to all rate payers within the catchment area of the wind farm in order to capture nonresident dwelling owners. About 100 flyers/brochures has been distributed up and down Tuross road, Kybeyan road including sides roads such as Green and Hain’s rd. and to relevant properties from Kybeyan road to Nimmitable along the proposed transmission easement. There have been very few concerns raised in response to visits, telephone conversations and flyer distribution. Mostly the people are positive or agnostic only one has expressed to be against renewables in general but not hostile to the development. The local mailman and publican in Nimmitable have been consulted with regards to identification of dwellings and their owner and occupation status. He has not mentioned that any concerns have been raised or discussed with him on his mail route nor at his pub. Both pubs and the café in Nimmitable are informed about the development and their opinions sought. A number of local’s have been or are involved in various activities at the Dawson farm and the development in general. These are local’s that have business activities across the broader Kybeyan and Tuross area and are in regular contact with the residence of the great area. Several business and community groups in Nimmitable has been met face to face and information about the project has been exchanged. Based on the proponents and associate’s activities we are confident that the broader community is well informed about the proposed development. During the next phase of the development community engagement is planned to be ramped up and public information meetings will be conducted to inform the local residents about the proposed development and the impact it may have on the area.

1 Introduction This letter contains updated information about preliminary noise level predictions from the proposed Elysian wind farm at nearby sensitive receptor locations. It presents predicted levels at the receptors and a noise contour map with noise levels in dB(A). The objectives of this assessment are to undertake a preliminary assessment of noise from the wind farm operation to inform future planning stage assessments. The assessment is based on wind turbine noise criteria determined in accordance with the NSW Wind Energy: Noise
Assessment Bulletin (NSW Bulletin).
2 Background levels and criteria Background noise level monitoring was conducted in 6 locations (see Appendix A) in December 2019 and January 2020. The data has been analysed in accordance with the NSW Bulletin and the results correlated with hub height wind speed at the wind farm site are provided in Table 1. Table 1 Measured background levels

The predicted equivalent noise level (LAeq,10 minute), adjusted for tonality and low frequency noise in
accordance with these guidelines, should not exceed 35 dB(A) or the background noise (LA90,10 minute) by
more than 5 dB(A), whichever is greater, at all relevant receivers for wind speed from cut-in to rated power of
the wind turbine generator and each integer wind speed in between.

Based on the above, Table 2 presents the criteria for each of the logging locations for wind speeds from 3 to 14 m/s, which corresponds to the range of cut-in to rated power of typical wind turbines. Table 2 Criteria based on background noise measurements

As the background levels were generally under 30 dB(A), the criteria for most locations and wind speeds will be 35 dB(A), with the exception of higher wind speeds at Location 1 and Location 6. At 9 m/s, which corresponds to the lowest wind speed at which many wind turbines reach their maximum sound power level, the noise criterion is 35 dB(A) for all monitoring locations.
3 Preliminary assessment of wind turbine noise
3.1 Prediction methodology SMEC has advised that the potential Wind Turbine Generator (WTG) model would be similar to a Vestas V162-5.6 MW, which has the following properties: • Rotor diameter of 162 m • Serrated trailing edge • A maximum sound power level of 104.0 dB(A) • A hub height of 149 m • A planned tip height maximum (ground to tip of vertical blade) of 230 m Table 3 presents the octave band sound power level spectrum upon which this assessment is based, which correspond to the sound data of a 5.6 MW WTG at the lowest rated power wind speed of 14 m/s.

To predict wind farm noise levels from Elysian Wind Farm, an environmental noise model has been developed in SoundPLAN version 8.1 environmental noise prediction software. The noise model implements the ISO 9613-2:19961 prediction algorithm with corrections as recommended by the UK Institute of Acoustics A Good Practice Guide to the
Application of ETSU-R-97 for the Assessment and Rating of Wind Turbine Noise (Good Practice Guide) In accordance with standard prediction procedures for wind farm noise, predictions have been undertaken on the basis of the following parameters: • WTG and residence locations as per the coordinates detailed in Appendix A. • Topographical contours provided by ELVIS - Elevation - Foundation Spatial Data. • Ground absorption factor of 50% representing mixed reflective and absorptive ground. This corresponds to a
value of G = 0.5 in accordance with ISO 9613-2:1996. • Receiver height of 1.5 m above ground. • Temperature of 10˚C and relative humidity of 70%. • +3 dB applied to the predicted noise level from any WTG where concave topography observed as per the UK
Institute of Acoustics Good Practice Guide definition • Topographical shielding limited to 2 dB. • Application of a 1 dB uncertainty factor to the predicted noise levels to account for any future variation in WTG
sound power level. This prediction methodology is in accordance with that recommended by the UK Institute of Acoustics Good Practice Guide with the exceptions that: • The Good Practice Guide recommends a receiver height of 4 m above ground rather than 1.5 m above ground.
A receiver height of 4 m above ground would increase predicted noise levels by approximately 1.5 dB. • The Good Practice Guide recommends that 2 dB be subtracted from predicted noise levels to adjust predicted
Leq noise levels to the assessed L90 noise levels. As in the UK, the SA Guidelines also use the L90 metric to quantify wind turbine noise levels but this correction has not been adopted for this assessment.
Given that the above two changes effectively negate each other, the predicted noise levels using the adopted methodology are considered to be consistent with the IoA Good Practice Guide. It is also noted that this methodology has been shown to accurately predicted downwind noise levels for Australian sites with sloping or relatively flat topography.2
3.2 Preliminary prediction results Table 4 on the following page presents the predicted wind turbine noise levels for the preliminary layout at each receptor within 12 km of a WTG location. The predictions are based on the WTGs operating at rated power and for the receptor being downwind of the wind farm. Lower noise levels would generally be expected for lower wind speeds and for situations where the receptor is not downwind of the wind farm. The highest predicted noise level is 41 dB(A) (for a non-associated receptor). A noise contour map showing the predicted noise level contours for the preliminary layout is included as Appendix A. Further planning stage assessments will be carried out and the following will be considered: • Updated wind farm noise predictions to reflect the finalised layout and WTG selections. • Ensuring appropriate noise agreements are in place with associated receptors.

For this high-level preliminary assessment, receptors that are predicted to have a noise level greater than 35 dB(A) have been highlighted in blue. These receptors are flagged as likely risk of exceedance and would require measures to address the predicted exceedance. Such measures would generally involve: • Implementing appropriate agreements with the landowners of these locations. • Altering the wind farm layout to reduce the predicted noise level to 35 dB(A) by relocating or removing WTGs. • Curtailing wind turbine operation under specific conditions by operating WTGs at lower sound power level
modes. Note that curtailment requirements for particular turbines may be significant if a reduction of more than 2 dB is required at a particular receptor.

Preliminary Aboriginal Heritage Assessment: Elysian Windfarm, Kybeyan, NSW

1. INTRODUCTION
1.1 Background
This document is a preliminary archaeological assessment of the proposed ‘Elysian’ wind farm (EWF) at
Kybeyan, ~23km north east of Nimmitabel, south east NSW (Figure 1). It considers issues relating to
Aboriginal heritage to the extent required to prepare a Preliminary Environmental Assessment for the EWF
development. Located in the Snowy-Monaro Regional Council LGA, the study area comprises the footprint
of 30 proposed tower locations and connecting infrastructure. The study is a desktop assessment using the
results of prior larger local studies to inform an analysis of archaeological potential.
Access Archaeology & Heritage (AAH) was engaged by Elysian Wind Farm to prepare the assessment.
1.2 The Nature of the Development
At the time of preparing this document there are thirty wind turbine tower locations proposed (Figure 2).
These locations will each have a development footprint of between 0.5 to 1 Ha, and access tracks will need
to be created to the majority with the current layout requiring ~23.5km of linking access tracks (~7ha of
footprint).
1.3 Project Objectives
The objectives of this project were:
Undertake a search of the NSW Office of Environment and Heritage (OEH) Aboriginal Heritage
Management System (AHIMS) database to determine if there had been any archaeological material
recorded in the subject land.
To undertake a landscape assessment to determine if there are landforms with a high potential to
contain Aboriginal objects and to what extent they coincide with proposed tower locations.
Complete a report on the assessment and present recommendations for any further work required.

2. LEGISLATIVE FRAMEWORK 2.1 The National Parks and Wildlife Act 1974 (NSW)
In NSW, Aboriginal heritage objects and places are protected mainly by the National Parks and Wildlife Act
1974 (NSW) (the Act) which contains provisions making it illegal to harm Aboriginal objects and Aboriginal
places without appropriate defence or permission. The Act is presently administered by the NSW Office of
Environment and Heritage (OEH). Under definitions provided in the Act:
Aboriginal object means any deposit, object or material evidence (not being a handicraft made for
sale) relating to the Aboriginal habitation of the area that comprises New South Wales, being
habitation before or concurrent with (or both) the occupation of that area by persons of non-
Aboriginal extraction, and includes Aboriginal remains.
Aboriginal place means any place declared to be an Aboriginal place under section 84.
If Aboriginal Objects are harmed, there are two levels of offence that Individuals or corporations may be
faced with. Knowingly or deliberately harming or desecrating Aboriginal places/objects is the higher of the
two levels. Lower level offences are known as ‘strict liability’ offences, that is to say they are offences
regardless of whether or not the offender knew they were harming an Aboriginal object or desecrating an
Aboriginal place. A person or corporation may have a defence against such prosecution where they have:
An Aboriginal Heritage Impact Permit (AHIP) authorising the harm (s.87(1))
Exercised due diligence to establish Aboriginal objects will not be harmed (s.87(2))
Due diligence may be demonstrated by following requirements described in the National Parks and Wildlife
Regulation 2009 (the Regulation) or a code of practice adopted or prescribed by the NPW Regulation
(s.87(3)).
2.2 The Due Diligence Code of Practice for the Protection of Aboriginal Objects in NSW 2010
The Due Diligence Code of Practice for the Protection of Aboriginal Objects in New South Wales (the Code)
describes the process that must be followed to demonstrate due diligence in assessing potential harm to
Aboriginal objects by a proposed development or action. The Due Diligence Code sets out steps required to
make an assessment of whether or not proposed activities may impact Aboriginal objects. These are:
Step 1. Will the activity disturb the ground surface?
Step 2a. Search the AHIMS database and use any other sources of information of which you are
already aware
Step 2b. Is the Activity in an area or areas where landscape features indicate the presence of
Aboriginal objects
Step 3. Can any harm or the activity itself be avoided?
Step 4. Desktop assessment and visual inspection
Step 5. Further investigations and impact assessment
Addressing these questions will determine whether or not Due Diligence obligations for the protection of
Aboriginal objects are satisfied. If they are not, further approval (an AHIP) under the NPW Act is required,
and this may be a recommendation of the Due Diligence study.
2.3 The Environment Planning and Assessment Act 1979
The Environment Planning & Assessment Act (NSW) 1979 (EPAA) establishes a planning structure that requires
consideration of environmental impacts of new projects, including impact to Aboriginal cultural heritage. A
proposal classified as State Significant Development (SSD) or State Significant Infrastructure (SSI) under the
EPAA is exempt from the requirement to obtain AHIPs to undertake works that may harm Aboriginal Objects.
Definitions of harm outlined in the NPWA are obviated once a development is classified as SSD or SSI and
permission instead rests with the Secretary of the Department of Planning and Environment.
Preliminary Aboriginal Heritage Assessment: Elysian Windfarm, Kybeyan, NSW
June 2019 Page 5
In this process the EPAA requires consideration of possible impact to cultural heritage that may arise from
development activities and while formal AHIPs are not required a formal assessment process must be
documented and it is current practice for this process to follow standards and guidelines established by NSW
OEH for these purposes, in particular those steps outlined in Aboriginal Cultural Heritage Consultation
Requirements for Proponents 2010.
3. ENVIRONMENTAL BACKGROUND The proposed tower locations follow, broadly, the Kybeyan Range, itself part of the Great Dividing Range
which forms the watershed between drainages flowing eastwards to the sea, and those flowing westward
into the Murray-Darling basin – in this instance via minor creeks into the Numeralla River and on into the
Murrumbidgee River. It is on the very eastern edge of the Monaro region, part of the Eastern Uplands of
south eastern Australia (Jennings and Mabbutt 1977). The location is placed into a further subdivision of the
eastern uplands, being Monaro Tableland region of the Kosciuszkan Uplands Province (Pain et al 2011:19).
Containing four distinct sub-regions, the Monaro is an area of high tablelands and mountains (Costin 1954,
Flood 1980). It is bounded by the Kosciuszko Highland in the west, the coastal escarpment in the east and
the Victorian border in the south (Taylor 1994). The northern boundary is less distinct than the other
boundaries, with some researchers including the land up to and including Canberra and Queanbeyan, and
others defining the northern boundary around Bredbo (Tylor 1994:1). The four Monaro areas described by
Costin (1954) are alpine, sub-alpine, montane and tableland, with the study area located in the Tableland.
All of the proposed turbine locations are underlain by early Devonian Glenbog Granodiorite, although the
wider area is geologically complex (Figure 4). Granodiorite is not a stone normally associated with
manufacture of stone artefacts, although the Adaminaby group formations have potential to contain pockets
of material suitable for this purpose, and indeed a source of good quality quartz and chalcedony has been
recorded near Tuross Falls (Dearling 2007).

The proposed tower locations are situated on high knolls, ridges and saddles to take advantage of elevated
topography. These higher points of topography are generally of lesser agricultural value and therefore have
not been subject to clearing and retain a cover of native eucalypt forest vegetation. Logging has occurred
through parts of the area.
4. ARCHAEOLOGY OF THE LOCAL AREA 4.1 Ethnohistory.
Background and Limitations
Ethnohistorical records are documentary pieces of evidence that record observations of Aboriginal people by early
European explorers and settlers. They are useful in the reconstruction of the picture of Aboriginal life before the
European settlement. Like all historical records they fall into different categories of direct observation and include, for
example:
journals from explorers and early European occupants of the area – including surveyors, and government
officials (direct and contemporary observations recorded close to the time of the event);
later reminiscences by long-time residents or travellers;
secondary documentation by writers who did not actually observe events or people but were told about them
by people who did observe events.
In research and heritage management studies ethnohistorical records are examined with two main purposes. The first,
and most practically applied, is to inform researchers of the range of material remains that could reasonably be
expected to occur in any given study area, and where that material might occur. So, for example, where an early
observer describes how Aboriginal people in the local area made fine canoes out of sheets of bark cut with stone
hatchets, one might reasonably include scarred trees to the types of archaeological site that could be expected in the
area, and realise that ground stone hatchet heads might occur in the artefact assemblage. The second main use of
ethnohistorical records in such studies is to add a human element to the research and analysis of archaeological
materials and places.
While ethnohistorical records are a valuable resource in the reconstruction of a picture of pre- European Aboriginal life
and material culture, there are limitations to their use. One of the primary limitations is that by their nature they are the
sporadic records of untrained observers of varying quality and reliability, as opposed to systematic studies. Further,
they are products of their times and, like any observation or historical description, they can be value laden. As a further
caution it is to be noted that changes to traditional Aboriginal society and life ways in south east Australia were rapid
after the arrival of Europeans in 1788, so it is unlikely that the earliest recordings of Aboriginal people in a given area
were of a people completely unchanged by European influence - either through being ravaged by European disease or
having contact with European material possessions. Diseases (notably small pox and influenza) were carried out from
Sydney by Aboriginal people and infected the wider Aboriginal population prior to their contact with Europeans.
For the purposes of this study, ethnohistorical records are informative in terms of predicting and explaining the sorts of
sites that might occur in the study area, analysing archaeological material that might be found, and in assessing
significance.
.
Ethnohistory Summary
The study area is situated in a territory generally acknowledged as Ngarigo country (Howitt 1904, Tindale 1974, Flood
1980). Documentary evidence regarding Aboriginal people is relatively sparse, surprisingly so, given the
acknowledgment that Aboriginal people were closely associated with the earlier phases of European exploration and
settlement (English 1985: 21). It has been suggested that the scarcity of references to Aboriginal people in explorer’s
journals is the result of deliberate avoidance of them by Aboriginal people (Lea-Scarlett 1968).
Some material culture1 is described in the early documentation. The observed tools and possessions included spears
(barbed and unbarbed), spear throwers, clubs, shields, boomerangs, stone axes, yam sticks, bark vessels, canoes,
apparel made from skins (possum and kangaroo), shell and stone scrapers, bone needles, and bark huts (Wright 1923,
1 Material Culture is that part of the culture of a people physically expressed or evident in the things they made and used. It might include tools, ornaments, clothing, and structures.

Helms 1895, Bennett 1834, all in Flood 1980:49-60). Stone axes in particular were said to be highly prized with men
rarely going anywhere without them tucked into a fur belt around the waist (Graham 1863). Bark was a material in
ubiquitous use for a number of purposes, primarily shelter, containers and canoes. In the early to mid 1830’s Edward
John Eyre purchased a land grant that he called ‘Woodlands’ which bounded on the Molonglo River between
Queanbeyan and Captains Flat. He records Aboriginal people being employed to cut sheets of bark to assist in the
construction of a shearing area. He records:
The bark was cut from the box or stringy bark trees by the blacks who are very skilful and expeditious in doing it.
Having selected a suitable tree the black fellow begins by cutting a ring round the tree thro’ the bark to the wood,
just where the lower end of the sheet of bark is intended to be. He next cuts with his tomahawk little steps in the
bark about half an inch deep, about two feet apart, alternately on the right and left, into which he puts his great toe
as he mounts from one to the other, pressing his feet and legs against the trunk…. For tho’ he uses his hands in
catching hold of the tree from time to time as he rises, yet he can stand on these little notches alone and keep both
hands free to use in whatever he may be about. In smaller sized trees that he can grasp with his arms he will run
up as rapidly as possible without cutting steps or aid of any kind. Having ascended to the requisite height he again
cuts a ring around the tree where the top of the sheet of bark is to be and then, gradually descending, makes a
perpendicular or longitudinal cut straight down from the upper ring to the lower one. With small pointed sticks he
again mounts and inserting them on each side of the perpendicular cut between the bark and the wood, he
gradually loosens the former from the latter until at last he gets it stripped off in one unbroken piece forming, when
stretched out flat, a sheet from six to twelve feet square, according to the size of the tree. To prevent the bark from
cracking when being thus stretched out it is heated inside with fire, just as a cooper heats a cask to make the
staves bend as he wishes. The same means are used to bend the bark into shape when required for a canoe…I
have often seen canoes made of a single piece of bark capable of holding six or eight people. Generally these
were cut from large river gum trees…When dry these sheets of bark retain their flat shape - are from an inch to an
inch and a half thick – quite impervious to any rain and, of course, most useful in the construction of temporary
dwellings, sheds or other buildings. A single sheet properly stretched out and propped up with sticks forms and
admirable shelter for the night from any rain, and is constructed by a black fellow, where the proper trees are to be
found, in a very few minutes (Eyre 1984:55-56)
Aboriginal food items recorded in the ethnohistoric literature include possum,
bandicoot, snakes, various macropods, wombats, emus, brolgas and other birds,
lizards, 'native cats', fish, yabbies, mussels, bogong moths, yams, berries and grass
seeds. (Bennett 1834, Bluett 1954). In addition, the author of this report has
personally observed and gathered large clusters of very large field mushrooms in the
Kybeyan area, which would have easily been a source of seasonal abundance.
The ceremonial and ritual aspects of the lives of local Aboriginal people were rich and
intricate. Class and totem systems are recorded for Aboriginal people of the region
(Howitt 1904:101-102). Men’s initiation ceremonies, variously called the Kuringal or
Bunan involved tooth evulsion and ceremonies inside earthen mounds. (Howitt 1904:
563-565).
Local burial customs included binding of the body into a foetal position and interment
with all the deceased’s weapons and implements. Howitt records “spears and nets
were included; even in one case a canoe was cut into pieces so that it could be put in
the grave. Everything belonging to a dead person was put out of sight” (Howitt
1904:461-462). In the region burials have also been recorded in caves and hollow
trees (White and Cane 1986:44). Clark recorded oral history from near Boorowa
suggesting that Aboriginal people had been buried at the base, and at the top of a hill, the latter of which occurred
between large broken rocks. He specifically notes “from the top of the hill one has a commanding view of the
surrounding country side” (Clark 1977:16). This description has analogies to Wright’s description of the burial of Hon
Yong (Onyong) who wrote “His grave was on top of a rocky hill…A tunnel about six feet long was excavated and his
body was inserted, with his spears (broken in half), his shield, nulla nulla, boomerang, tomahawk, possum rug and
other effects…” (Wright 1923:57).

The dislocation of Aboriginal people in the face of the European settlement appears to have been rapid and traumatic.
Smallpox was observed at Yass in 1844, and it is highly likely that the disease had reached the Southern Tablelands at
a somewhat earlier date, although possibly not before 1830. Other diseases against which the Aborigines had no
immunity included measles and influenza (Flood 1980: 32). In a little over fifty years after the first European incursion
into the area, the fully traditional way of life had disintegrated. (Andrews 1979).
While the purely traditional way of life passed, the descendants of those people retain their Aboriginal tribal identity.
They are genuinely concerned about the preservation of their cultural heritage.
The ethnohistorical record provides the following information that informs the preparation of this study.
1. The local area contains a range of resources that are recorded in the ethnographic record;
2. The last phase of traditional Aboriginal life ceased in approximately the mid 1880’s, so sites like stone
artefact scatters date to a time before this;
3. Bark was used for many traditional purposes, the occurrence of scarred trees is a possibility although the
widespread clearing and logging would have compromised the potential for large numbers of scarred trees
to be found.
4. Given the traditional and semi-traditional activities that were undertaken in the area into the late 19th
century, the occurrence of European materials as part of the Aboriginal archaeology is a possibility (for
example, glass or ceramic flaked artefacts).
4.2 Archaeological Background
The broader region of south east NSW has been occupied by Aboriginal people for at least 21,000 years. Human
occupation at Birragai rock shelter has been dated to ~21,000 Before Present (BP) (Flood et al 1987), Burrill
Lake rock shelter near Ulladulla has been dated to ~20,000BP (Lampert 1971) and Bulee Brook 2 in the south
coast hinterland has been dated to ~19,000BP (Boot 1996a & b, 2002), these three sites all providing a
reasonably consistent picture of the time human occupation of the region becomes archaeologically visible.
Flood’s pioneering archaeological work in the NSW high country emphasised the potentially seasonal nature of
occupation, concentrating on ethnohistorical accounts of Bogong moth collection (Flood 1980). She suggested
that Ngarigo people occupied the lower hinterland during winter and moved into the high country in summer to
collect the moths. Despite arguments refuting the importance of Bogong moths as a seasonal staple (Chapman
1977, Bowdler 1981) or that it was a resource that fostered social cohesion and exchange rather than being a
staple food (Kamminga et al 1989), seasonal use of the highlands continues to be the main interpretation of local
Aboriginal occupation.
Heffernan and Boot conducted a wide ranging study of the South East Forests (Heffernan and Boot 2000). In a
survey transect along Kybeyan Road they recorded eight open artefact scatters and five isolated finds.
Dearling (2004) undertook a study of a number of nature reserves and state conservation areas in environmental
/ topographic locations similar to the present study area. Among the areas he inspected the following are
particularly relevant:
Kybeyan Nature Reserve: three open artefact scatters and two isolated artefacts (14 artefacts in total)
all within a large grassy clearing, crossed by drainage lines, soaks, and minor wetlands. Seven stone
materials were recorded, although the small number of artefacts overall makes the sample difficult to
draw extensive conclusions. The materials were chert (28.6%), quartz (28.6%), silcrete (14.3%2),
indurated mudstone, chalcedony, volcanic, and unknown (each 7.1%).
Kybeyan SCA: One quartzite broken flake was recorded.
Dangelong Nature Reserve/Mowles Creek: six open artefact scatters and three isolated (116 artefacts
in total). Most were found close to the junction of the Numeralla River and Granny’s Flat Creek. The
largest site at Mowles Creek contained 44 artefacts. Eight stone materials were recorded- silcrete
(71%), quartz (14.5), chert (7.3), volcanic (3.6%), and Indurated mudstone (3.6%).
Preliminary Aboriginal Heritage Assessment: Elysian Windfarm, Kybeyan, NSW
June 2019 Page 9
Coornatha Nature Reserve: This study area contained one artefact scatter and one isolated artefact
(total five artefacts). The isolated find was located in the area of basalt in the south east corner of the
Nature Reserve. Two stone materials were recorded, Chert (60%) and Quartz (40%).
At the ‘Warratah’ property at Kybean Dearling (2007) recorded seven Aboriginal archaeological sites, with an
overall a total of 53 stone artefacts. Quartz was the dominant stone material, with chalcedony, chert, silcrete and
volcanic artefacts also recorded (Dearling 2007:29). These sites were associated with low gradient terrain, either
spur crests or valley floors, with raised level terrain in proximity to water exhibiting the greatest artefact densities
(Dearling 2007:27-28). In a re-examination of part of this study area, Williams (2017) relocated Dearling’s site
WK-2 recording 31 flaked stone artefacts and further recorded a new site ‘WK-9’, an artefact scatter with 21
artefacts. Both of these artefact clusters were found on locally raised spurs in association with Greens Creek, a
small permanent watercourse.
In 2005 Dibden undertook an assessment of a proposed fence alignment at ‘Lone pine’, in Wadbilliga National
Park, ~7km south of the present study area. The fence was ~5.5km in length, traversing a range of landforms
and vegetation. Seven archaeological sites were recorded mainly in association with spur crests and drainage
depression topographic features of low gradient. One major site consisted of more than 80 artefacts over a
200m x 10m area on a knoll and spur crest. Materials recorded included silcrete, quartz, quartzite, volcanic and
chert (Dibden 2005:20).
Dibden (2009) undertook an assessment of the Boco Rock Wind Farm west of Nimmitabel, recording Aboriginal
stone artefacts at 56 locations. Elevated, relatively level ground close to the Maclaughlin River was found to be
the most archaeologically sensitive terrain. Higher terrain such as plateau and high ridge lines exhibited stone
artefacts, but at a far reduced density. A total of 237 artefacts were recorded, with quartz and silcrete being the
dominant stone materials (Dibden 2009: Appendix 1).
Dibden undertook an archaeological assessment of proposed maintenance work on Wadbilliga Road in
Wadbilliga National Park (Dibden 2010). The project assessed the potential impact of widening the existing road
by ~1.5m over a total of 5.5km. The project required the installation of nine culverts and removal of 16 trees
(Dibden 2010: 3). The study recorded Aboriginal cultural material in the form of stone artefacts at five locations,
some of which were revisits to sites recorded some years previously. An extensive scatter of cultural material
was located across the area of 2 previously recorded sites (Dibden 2010: 35). The scatter was recorded as
occurring over 690m on the east side of the Wadbilliga River, with an earlier recording by Boot noting 1185
artefacts (Dibden 2010:35). The remaining four locations were isolated artefacts, and these objects were found
in disturbed contexts and topographic locations not conducive to camp site locations.
In 2015 Dibden undertook an assessment of proposed work on the Kybeyan Radio Tower and Tuross Falls Road
in Wadbilliga National Park (Dibden 2015). The purpose of the project was to assess sections of Tuross Falls
Road where Aboriginal objects were known to occur, in addition to the small area of proposed disturbance at the
Kybeyan Radio tower (Dibden 2015:35). Of the seven site locations investigated, stone artefacts were
observed at three, with no objects found at four previously recorded locations. The Kybeyan radio tower location
exhibited no archaeological material.
CHMA (2016) undertook a preliminary assessment of a proposed wind farm ~25km south of the present study
area. Engaged to provide a preliminary heritage assessment of the wind farm footprint as it was then designed,
the sample survey recorded 13 previously unrecorded sites, termed GH1-GH13 inclusive, and five Potential
Archaeological Deposits (PADs) (GH PAD1-5). Of the sites recorded, four were open artefact scatters and nine
were open artefact scatters with associated PADs. Approximately 160 stone artefacts were observed (CHMA
2016:40-41), noting that the preliminary nature of the study precluded detailed recording and precise counts.
The study found that where good visibility coincided with broad, open flat crests or saddles within a reasonable
distances of water sources cultural material was found, suggesting a widespread scatter of material over those
Preliminary Aboriginal Heritage Assessment: Elysian Windfarm, Kybeyan, NSW
June 2019 Page 10
landforms (CHMA 2016:39). A subsequent more detailed archaeological survey was undertaken in 2017 which
identified an additional 22 sites including scatters of artefacts, isolated artefacts, potential archaeological
deposits scarred trees and a potential quarry (Williams 2018:16-24). 730 stone artefacts were recorded with
nine stone materials represented and sixteen technological categories of artefact recorded. Quartz and silcrete
artefacts were recorded in approximately equal proportions although there were twice the number of quartz cores
and core fragments as there were of silcrete. This suggests that quartz artefacts were created from more readily
available and/or smaller nuclei and that silcrete was a more curated material. It was concluded that the
archaeological evidence recorded suggested regular use of the study area as a transitory landscape (Williams
2018:31). Evidence of Aboriginal occupation was widespread in locations that offered level to gently sloping
topography, but archaeological evidence in the form of artefact scatters also occurred in areas of steeper
gradient close to permanent water sources.
The majority of archaeological studies in the area have overwhelmingly recorded scatters of stone artefacts, but
other types of archaeological sites have been recorded on the Monaro. In 1991 the remains of two Aboriginal
people were discovered eroding out of the bank of Rock Flat Creek at Bunyan ~10km north of Cooma. Despite
heavy disturbance it was intimated the people were buried side by side at the same time. Grave goods were
found with the human remains, including red ochre, two pebble hammer/anvil stones, five bone points made of
kangaroo fibulae eight macropod mandibular rami and 327 pierced kangaroo teeth – all upper incisors pierced to
allow them to be strung (Feary 1996).
In 1988 Comber undertook an examination of four quarry/reduction sites between Bredbo and Cooma (Comber
1988). Two of the quarries (A and B) are tabular chert, one (C) was basaltic andesite and one (D) was dacite.
4.3. AHIMS search.
A search of the OEH AHIMS register was undertaken on 28/03/2019, over a ~1,295km2 area centred
approximately on the proposed extent of turbines. Within this boundary there were 107 previously recorded
sites, only one of which occur within 1km of a proposed turbine location. The nearest known site to a proposed
turbine is site 62-2-0412 (WK-7) which is ~300m east north east of proposed turbine 30. The locations of these
previously recorded sites are illustrated in Figure 4.
4.4. Site Location Model
Pursuant to the above, the following types of sites were considered to have potential to occur in the inspection
area:
Artefact scatters
These are a very common site type and consist of stone artefacts found scattered on the ground surface and are
often referred to as an open camp site. In most archaeological contexts, an artefact scatter has been deflated by
erosion, or it more typically involves a sub-surface deposit of varying depth. Artefact scatters may represent :
the evidence of camp sites, where everyday activities such as habitation, preparation and consumption
of food and storage of tools have occurred;
hunting or gathering events;
other events spatially separated from a camp site (e.g. tool production or maintenance); or
transitory movement through the landscape.
The detection of artefact scatters depends upon conditions of surface visibility and ground disturbance and post-
depositional change through either sediment accumulation or surface erosion. Vegetation cover and deposition
of sediments generally obscures artefact scatter sites and prevents their detection during surface surveys. High
levels of ground disturbance can also obscure or remove evidence of a site. Isolated finds are single artefacts.
They may be representative of simple, singular discards or may be all that is visible within a site, with other
material either obscured from view or buried beneath the surface. The ability to observe surface archaeological
material at a site will change with altered environmental conditions, therefore visits to the same site at different
times almost always result different observations. Artefact scatters might occur in any area with low gradient, but
Preliminary Aboriginal Heritage Assessment: Elysian Windfarm, Kybeyan, NSW
June 2019 Page 11
will be most dense and easily detectable on level, raised, well drained locations close to water sources or other
resource zones such as wetlands.
Scarred trees
Scarred trees are those from which the bark has been removed for the manufacture of containers, shields or
canoes. Small scars may also represent toe-holds cut into a tree to enable climbing. They are a common site
type in the river flood plain corridors. It would be unlikely that scars in this location would be the result of canoe
manufacture, so those that are the result of making containers or shelters would be more likely. Scarred trees
might occur at any location where mature native trees remain.
Burials
Human burials have only rarely been discovered in the region, but those discovered have been found in deeper
soil of creek margins (Feary 1996). It is unlikely that any surface survey would detect human burials, and the
turbine locations are on high points that will in all likelihood have thin soil profiles, but as the area is drained by
several creeks which may require crossing by connecting tracks and/or power cables it is possible that this site
type may occur in land subject to disturbance by the establishment of the development.
Stone Quarries
Hiscock and Mitchell (1993: 19-23, 32) have defined an Aboriginal quarry as being the location of an exploited
stone source. This definition was adopted by them as it took in the widest possible range of sites related to stone
procurement strategies. As well as including areas exhibiting visible evidence of exploitation, this definition can
be extended to areas where procurement techniques have left little or no evidence of activity. Aboriginal stone
quarries may range from large, well organised sites and cover may hectares (e.g. the Mount William greenstone
quarries, McBryde 1984) to simply locations of cobbles or pebbles which can be easily collected as required (cf.
Gould 1977:162-8, Jones and White 1988:57-8,). The underlying geology of the subject area is not one where
Aboriginal quarries would be expected, but stone hatchet quarries are a possibility.
Potential Archaeological Deposits (PADs)
PADs may be defined using topographic and/other environmental variables where it is considered highly likely
that archaeological material may occur under the ground, but surface visibility is poor.
5. METHODS The Aboriginal Heritage Information Management System (AHIMS) site register was consulted to determine
if any sites had been previously recorded in, and near, the subject area, this included both basic and
extensive searches.
Previous archaeological studies were reviewed to familiarise the consultant with local archaeology, and recent investigations in the area. Aerial (satellite) imagery was consulted as a guide to topographic assessment. The assessment of topographic location was undertaken with recourse to publicly available topographic maps with contours at 10m intervals on the NSW Spatial Information Exchange platform (SIX Maps). Tower locations were pin pointed by identifying GDA coordinates of each tower in QGIS ad transferring those to the coordinate tool in SIX Maps.

6. REGISTER SEARCH AND SITE ASSESSMENT
6.1 AHIMS Search
A search of the AHIMS register maintained by NSW OEH was undertaken on 14 December 2018 over an
area of ~1,295 square kilometres (~36km x ~36km) centred approximately on the proposed extent of the
turbines. This search showed 107 sites recorded previously in that area (Figure 4 and Attachment 1). This
suite of sites comprised occurrences of surface stone artefacts with only two exceptions. There were:
62-3-0061, Grinding Grooves at Back River,
62-3-0063, Scarred Tree at Queens Pound on Wadbilliga River.

The analysis summarised in Table 1 shows the majority of proposed turbine locations to coincide with ridge
line features such as crests, knolls and plateaux. Previous archaeological studies in the region identify
these elements as having higher concentrations of archaeological material than surrounding sloping
topography and in fact in hilly to undulating terrain serve to focus human activity in smaller areas of low
gradient. This archaeological material is in the main scatters of stone artefacts of varying density. Where
areas of low gradient coincide with watercourses archaeological occurrences become more frequent and
more dense. As these proposed turbines occur at high points in the landscape their archaeological potential
is lessened by distance to fresh water, but prior studies have also shown that water sources can occur at
higher points in the landscape, particularly on plateau type elements (cf. Williams 2018:19).

7. CONCLUSION
The requirements of efficient wind farm establishment are such that the locations of proposed turbines often
coincide with topographic elements that have higher archaeological potential, likewise access roads often
follow crest and/or level topography for ease of construction. The suite of proposed locations examined in
this study fits that coincident model in large measure, and as such the majority of proposed turbine locations
should be subject to a detailed field inspection prior to development occurring. This inspection should take
the form of an Aboriginal Cultural Heritage Assessment, following the requisite guidelines and standards
issues by the NSW Office of Heritage and Environment.
Prior to such inspection the proponent should examine the design of the proposed development with
reference to more detailed topographic information (for example, LiDAR generated contour maps) in order to
determine if any proposed turbine locations and or access tracks are now on, or are able to be moved to,
topography with a slope of >70, as this would place any such turbine / compound in zones of lower
archaeological sensitivity.

8. DUE DILIGENCE DECISION PROCESS
This decision matrix has been developed by the NSW OEH as one that provides satisfactory process for the
purposes of undertaking due diligence (NSW DECCW 2010:10).
Preliminary Aboriginal Heritage Assessment: Elysian Windfarm, Kybeyan, NSW
June 2019 Page 16
9. RECOMMENDATIONS. Pursuant to the information provided above, it is recommended that:
1. Prior to development the proposed turbine locations, compounds and ancillary works footprint should be subject to a detailed archaeological assessment complying with standards, guidelines and any other conditions issued by the NSW State Government.
2. Prior to the completion of the study noted in Recommendation 1 the proponent should avoid undertaking, commissioning or allowing ANY ground disturbing work or vegetation clearing associated with this development.
3. Where such ground disturbing work is unavoidable prior to the issue of overall approvals, the proponent should prepare a Due Diligence Aboriginal Heritage Assessment in accordance with NSW OEH standards and guidelines.
The proponents, their employees and agents are reminded that the National Parks and Wildlife Act (NSW) 1974 (as amended) is a strict liability act and under its provisions it is an offence to destroy, deface or otherwise disturb an Aboriginal Object without first obtaining the consent of the Director General of the NSW NPWS.
