2. Background

2.1 Purpose of the proposal

The clearance is for the establishment of a solar farm.

2.2 Background

Yates Electrical / Green Gold develop small solar farms producing power into the electricity grid; between 2 and 10ha around South Australia . In most cases the sites selected for the solar farms are placed on low valued farming land however, on occasions, land that is deemed suitable due to its proximity to the national power grid and connection suitability are selected for development. This land may contain native vegetation on all or part of the land.

This site is one of those where connection and line capacity is exceptional due to existing infrastructure from previous coal fired power generation and the electricity distribution network. The solar panels have a operating life of approximately 30years. The proposed development covers 4 allotments previously zoned as potential residential blocks. These allotments have been interfered with over time with a drainage line, soil dumping and people accessing the site by 4 x 4 / motorbikes with many tracks across the land. During the development of the coal fired PowerStation (now closed) a road past this site was created with Eucalyptus trees planted as part of a beautification program. Many of these trees have died due to high soils salinity. Over years site has naturally regenerated with saline tolerant species as parts of the land are influenced by groundwater seepage via tidal movement after the landscape was altered during previous industrial use of the general area. The site works will again modify the land form by creating a relatively flat land to build on. This application is over 4 adjoining allotments needed to make up the desired area to take advantage of the existing poles and wire infrastructure remaining from the dismantled coal fired generation plant therefore complete clearance will occur. The proposed project has gone through a planning process with the assistance of Planning Chambers with development application approved by Port Augusta Council.

About this Solar Farm

1. The following provides technical information about the solar farm and justification for the project.

a) Northern Power station road solar farm is rated at 4.4MW, and will generate approx. 11,332MWh,.

b) The farm will be connected to the main grid via overhead power lines which will be extended if

necessary (please refer to site plans), and the power will be sent to nearby substations to feed local

demand. The electricity will be sold in the wholesale market via retailers.

c) This parcel was chosen due to its close proximity to distribution substations and relative strong

electricity networks in the local area.

d) The solar farms will be decommissioned after its 30-40 year lifespan with all structures removed

and land returned to its original conditions. Natural regeneration of species will occur during this

time. This process of natural regeneration is already occurring on other sites cleared for solar

farms.

e) As part of the process of approvals SAPN (South Australian Power Networks) must review the

demand requirements of the network and the existing infrastructure to handle the power load.

They approve all projects prior to the other businesses assisting work on their areas of expertise. f) Network works in a very complicated and dynamic way. All generations connected to the grid are

sent to a pool of the National Electricity Market. Because all consumptions draw power from this pool, It would be impossible to identify the electricity consumed comes from which generator. Demand and supply of energy also fluctuates significantly over a period of time, therefore, the network service provider/regulatory bodies can never provide the information of which area needs X amount of generation.

g) SAPN ultimately approve the connection. The connection is based on the networks capacity to accept the power we are generating. The location is very important and not all parts of the network can accept a large amount of generation.

h) As a whole the state has insufficient supply available especially in heat waves, adding generation to the network will assist with taking the demand from the network

2. Building impacts on the site

a) The site will be fenced with a 1.8m high chain security fence replacing the existing fence.. All

activities will occur within this fenced off area.

b) The Northern Power station road site access will be via access gate on Northern Power Station

Road without impacting on native vegetation.

c) No additional roads are required as all materials and equipment will be delivered via Local

Government Roads.

d) Location of lay down area or material storage is part of the site plan/ clearance area contained

within the fenced off boundary.

e) The natural vegetation in this area is deemed low fire risk (the vegetation types are recommended

for high fire risk areas). The screening vegetation proposed is a requirement of the Port Augusta

council and have been selected because they are local native species and meet the guidelines for

plant species/ heights around power lines.

f) The reason for placing the solar farm where it is proposed is to reduce impacts as much as possible

and utilise existing infrastructure. Northern Power Station, existing overhead line will be extended

to site to allow for HV cable connection. These poles will be constructed alongside the dirt road to

the south of property

g) Our planning involves a team of 5 businesses who consider all engineering requirements, planning

and environmental during weekly meetings. This experienced team has considered all connections

to all services i.e. communications, water, sewer/septic. There will be 2 water tanks (22500 litres

each) placed at 2 corners within the fenced off area, to provide water for the screen plantings.

h) All activities are contained within the proposed fenced off site plan. The clearance area is contained

within the fenced off area.

i) Port Augusta council has approved this application - refer to attachment 4 and 5.

3. Method

3.1 Flora assessment

A desktop review of possible species at the site was conducted using Nature maps, which provided the rating under

the NP&W 1972 and again reviewed using the Atlas of living Australia to identify other species that maybe present at

the site which enabled reviewing and referencing species listed on the EPBC act 1999 site.

The Bushland Assessment Field Datasheet was used to collect information from the site using the Bushland

Assessment Manual as a guide to fill out the Bushland Assessment Score sheet.

The Flora assessment was conducted at the time (2hrs) of site visitation using the process outlined in the Bushland

Assessment Manual. The vegetation association on the site were found to be homogeneous.

Further Flora assessment was conducted during a more comprehensive analysis some 4 months after the initial

review.

Samples of species requiring further identification were taken and identified by Dr Geoffrey Bishop using

identification books and internet searches.

No flora species were identified as listed under the NP&W 1972 or EPBC Act.

3.2 Fauna assessment

Our Fauna assessment was based on the site time spent on site identifying and writing down any species viewed or

observed during this time (2hrs). We used binoculars or visual sightings to spot fauna species.

Further assessments were conducted once it was considered either level 3 (seriously at variance) or level 4 clearance

was possible. This analysis included identifying any trails through the vegetation, markings, scratching, scats, and

diggings over 4 hours. The most noticeable species were Kangaroos x 4 and Rabbits (holes on the edge of the

proposed clearance area)

We also conducted a reconnaissance of the general area over 2 hrs to identify any potential fauna species.

In the office further review was made by:

• Desktop pre-review using The Atlas of Living Australia

• Species analysis via Nature Maps and Atlas of Living Australia (5km radius of site)

• Possible habitat use and clearance impacts developed from numerous sources including; 1. AofLA information on web 2. EPBC Act web review 3. NP&WS list 4. Birds Australia 5. Birds in Backyards 6. IUCN Red List of Threatened species

Discussions with colleagues regarding the proposed clearance and potential EPBC act referrals or potential habitat

loss or threats to rated species, it was agreed that the condition of the vegetation and impact of the clearance on

species using the vegetation was unlikely.

4. Assessment Outcomes Provide information on the following assessment criteria. For more information see the NVC’s Guide for Applications to Clear Native Vegetation.

4.1 Vegetation Assessment General description of the vegetation, the site and matters of significance

Provide a general description of the site including the following;

• Vegetation present,

The vegetation on the site has been modified over time with signs of past human activities such as building roads and other flat areas for industrial activities which has changed the drainage of the landscape. There has been a drainage line cut through the collective allotments and tracks through the existing vegetation causing modification.

The vegetation proposed to be cleared appears to be a representative of a regenerative coastal samphire community and is in fair to good condition given past history.

Some trees and shrubs have been planted along the Southern Boundary

• Landform, geography and soils

This area has had a history of modification and change during the building of Coal fired power generation and associated infrastructure. The local vegetation has not been treated as an asset in the past.

A small corner of allotment 10 is effected by a landlocked, tidal seepage issue.

Soils are moderate salty loam to extreme saline clay. The soils are not suitable for food production.

• Provide the Database search (BDBSA, EPBC, AoLA) results plus direct observations, or incidental records of or suitable habitat for NP&W Act listed species or EPBC Act listed species. If present, the location of these matters must be identified on a map.

Species provided in tables as attachments.

No NP&W Act listed species were found.

No EPBC Act listed species were observed on site, however the environment changed significantly some 2000m away to the West where the land form changes to the top of the Gulf

Details of the vegetation associates/scattered trees proposed to be impacted

Vegetation associations are present, on the site ;

4.2 Requirements of the Regulation

Provide information on how the proposed clearance meets the requirements of the regulation.

i. Identify the regulation under which the proposed clearance is applicable and demonstrate that it

meets all the criteria of the regulation contained in Division 5 and Schedule 1

Identify the applicable regulation and demonstrate the proposed clearance being undertaken in accordance with the requirements of the regulation.

The clearance would take place under Regulation 12(34) Infrastructure

Principles of Clearance (Schedule 1 of the Act) analysis Analysis Indication

No or Yes

a) It comprises a high level of diversity of plant species (patches of vegetation only) > 20

b) It has significant habitat for wildlife No (After review)

c) It includes plants of a rare, vulnerable or endangered species No

d) The vegetation comprises the whole, or a part, of a plant community that is rare, vulnerable or endangered (patches of vegetation only)

No

e) It is significant as a remnant of vegetation in an area which has been extensively cleared

No

f) It is growing in, or in association with, a wetland environment No

g) It contributes significantly to the amenity of the area in which it is growing or situated.

No

ii. Risk Assessment - determine the level of risk and provide information to support the risk assessment– see Guide for Applications to Clear Native Vegetation

Identify the level of risk of the application in accordance with Table 1 of the Guide for Applications to Clear Native Vegetation. This must include considerations of the following.

• Patch size = 9.77ha • Total Biodiversity Score = 572.57

Using table 1 of the Guide for Applications to Clear Native Vegetation the total biodiversity score is greater than 250 however is less than 2500 therefore the Risk Level is 4 seriously at variance with principles of clearance 1(b) of the act applies

of 30


iii. Provide any other information that demonstrates that the clearance complies with any relevant NVC guidelines related to the activity.

Escalating matters for consideration

The native plant species diversity score is 30 therefore clearance would be considered seriously at variance with Principle 1a of the NV act.

The threatened species score is 0.04 and a unit biodiversity score of 58.60 clearance would be considered at variance with Principle 1b of the NV act

No rare, vulnerable or endangered flora species were identified

Additional Information / Justification for clearance

1. The species identified within 5km of the site by AofLA give a false impression of the importance of this sites vegetation to threatened species given with possible only 3 species relying on the site and given the % of vegetation association remaining.

2. The project site is a combination of 4 parcels of Vacant Land with a planning classification of Rural Residential/ Rural living Allotments. This means each parcel of land could be built on (STCA / house and shedding), fenced and utilized by grazing livestock, horses or other human pursuits therefore losing a majority of the existing vegetation.

3. Further investigations indicate these allotments could be further subdivided (STCA) for additional houses or buildings further degrading the site.

4. This site is one of those where connection and line capacity is exceptional due to existing infrastructure from previous coal fired power generation and the electricity distribution network and associated 33kV poweline and substation infrastructure.

5. Investment in this site has been considerable, land purchase $240K along with engineering and planning costs of $225K. Build cost is around 4 - 5 million. Significant loss of income would occur if not approved with no income from that business.

Site restoration

6. During historical activities within this area (powerstation development) these sites have been cleared and vegetation damaged. The samphire/Chenopod vegetation association is extremely good at reclamation of degraded saline environments in this part of South Australia.

7. The area to be cleared will be allowed to regenerate after the installation of the solar panels. The natural regeneration process and the extent of species diversity is unknown, however given revegetation experience from samphire /chenopod landscape restoration it is expected this site to recover by 80% due rainfall concentration off the panels and low impact maintenance.

8. We are currently monitoring regrowth of native vegetation at a site at Port Pirie where the solar farm has been established. After just 8 months good examples of native vegetation recovery can be found. Due to the salinity on the site we are confident good species recovery of the site.

4.3 Address the Mitigation Hierarchy

When exercising a power or making a decision under Division 5 of the Native Vegetation Regulations 2017, the NVC must have regard to the mitigation hierarchy - see the Guide for Applications to Clear Native Vegetation

The NVC will assess the measures taken to avoid and minimize impacts on biodiversity and rare or threatened species or ecological communities within the property or immediate vicinity of the development.

Demonstrate how the clearance proposal addresses the following:

a) Avoidance – outline measures taken to avoid clearance of native vegetation such as making adjustments to the location, design, size or scale of the activity in order to reduce the impact.

This application covers 4 adjoining allotments; needed to make up the desired area to take advantage of the existing poles and wire infrastructure remaining from the dismantled coal fired generation plant. To do this complete clearance will occur.

Clearance for the security fence around the site and clearance to make the site workable.

All native vegetation will be damaged in some way during the development process due to the undulating nature of the site because the site needs to be leveled as part of the development process.

b) Minimization – if clearance cannot be avoided, outline measures taken to minimize the extent, duration and intensity of impacts of the clearance on biodiversity to the fullest possible extent. Yates Electrical/ Green Gold has experience in making sites ready for the installation of the panels. In some instances we use rolling the existing vegetation or we slash the existing vegetation or we lightly scalp the site. The fence perimeter will be scalped leaving roots in the soil for regrowth. As this site is undulating some of the land will be lightly scalped (NO roots systems removed) whilst other undulating areas will be covered with soil (cut and fill) in order to provide a flat surface to build / erect the panels. Areas that can be scalped (enabling regrowth) will be identified by to be scalped (by Environments by Design) with direction provided to the operators of machinery working on the site.

c) Rehabilitation or restoration – outline measures taken to rehabilitate ecosystems that have been degraded, and to restore ecosystems that have been degraded, or destroyed by the impact of clearance that cannot be avoided or further minimized, such as allowing for the re-establishment of the vegetation. It is well known sites containing chenopod and samphire species are very good at natural regeneration once disturbance has occurred. Given this site has been disturbed many years ago one would expect the same to occur, although shading of the panels my change the tolerance of some species to handle the shade. Bare areas will have native seeds spread over them after installation of the site is completed with further seeding into the winter months. A monitoring program of the site will demonstrate changes over time. We expect it to recover to a vegetation association and species representation that currently exists. Current analysis of another site similar to this is demonstrating early recovery after just 8 months. A visual screen around the perimeter of the block using Melaleuca halmaturorum and Atriplex nummularia will be planted.

d) Offset – any adverse impact on native vegetation that cannot be avoided or further minimized should be offset by the achievement of a significant environmental benefit that outweighs that impact. The NVC will only consider an offset once avoidance, minimization and restoration have been documented and fulfilled. The SEB Policy explains the biodiversity offsetting principles that must be met.

of 30


5. Significant Environmental Benefit A Significant Environmental Benefit (SEB) is required for approval to clear under Division 5 of the Native Vegetation Regulations 2017. The NVC must be satisfied that as a result of the loss of vegetation from the clearance that an SEB will result in a positive impact on the environment that is over and above the negative impact of the clearance. The Data Report must propose how the SEB will be achieved in accordance with the SEB Policy and Guide, by providing the following information.

DETERMINATION OF THE SEB OBLIGATION
