Executive Summary
61/16529/52778
Main Roads Western Australia (Main Roads WA) commissioned GHD Ply Ltd to
complete a Preliminary Environmental Impact Assessment (PEIA) for the Wiluna to
Magellan Section of the Goldfields Highway (618- 626 SLK and 636 to 647 SLK).
An increase in traffic along the highway associated with the Magellan Mine has lead to
an increase in maintenance costs of the highway. The highway is predominantly unsealed and Main Roads is proposing to seal a 15 km section from Wiluna to the
minesite.
A number of desktop assessments including database, literature reviews and consultation with State Government Departments were undertaken to determine the
potential environmental impacts of the development. These included identification and reporting of:
t Rivers, water catchments and drainage;
t Vegetation- Declared Rare and Priority Flora, Clearing;
t Weed management;
t Fauna;
t Aboriginal heritage;
t European heritage;
t Land use; and
t Construction phase impacts.
This PEIA indicates that the potential for environmental impact is considered to be
minimal. However, as requested by the Department of Conservation and Land
Management a flora and opportunistic fauna investigation was completed on the 81" to
91" of August 2005, and 291
" August 2005 to determine of any Declared Rare or Priority Flora species will be impacted. No Declared Rare Flora or Priority Flora were observed during the flora survey.
Up to seven registered Aboriginal sites were identified within close proximity to the
highway. A Section 18 Clearance under the Aboriginal Heritage Act {1972) has been granted via the Department of Indigenous Affairs. However, clearance for borrow pits
must be determined in conjunction with the Department of Indigenous Affairs.
No issues identified during the development of this assessment require referral to the
Environmental Protection Authority or referral to the Commonwealth under the auspices of the Commonwealths Environmental Protection and Biodiversity
Conservation Act (1999).
Wiluna to Magellan Section Preliminary Environmental Impact Assessement and Biological Survey
1. Introduction
61/16529/52778
Main Roads Western Australia (Main Roads WA) commissioned GHD Ply Ltd to
complete a Preliminary Environmental Impact Assessment (PEIA) associated with the
Wiluna to Magellan section of the Goldfields Highway. The specific sections of road
under scrutiny are 618- 626 SLK and 636 to 647 SLK (i.e. a distance of approximately
19 km of which Main Roads is proposing to seal15km).
The project location is depicted in Figure 1.
This PEIA has been prepared in accordance with Main Roads project brief and:
1 describes the significant aspects of the existing environment;
1 details the primary environmental and social impacts of the proposed works; and
1 provides recommendations for:
additional investigations that may be required to clarify the expected
environmental impacts of the proposed works;
developing appropriate management measures during the development of the
project design; and
- obtaining the necessary statutory approvals.
Based on the information provided by Main Roads, relevant stakeholders and database/literature reviews, the environmental and social aspects considered and
discussed in this PEIA include:
1 Rivers, water catchments and drainage;
1 Vegetation- Declared Rare and Priority Flora, Clearing;
1 Weed management;
1 Fauna;
1 Aboriginal heritage;
1 European heritage;
1 Land use; and
1 Construction phase impacts.

The Main Roads WA study brief required the desktop investigation to assess a number of issues. However, some of these issues are considered not be relevant to this study. Table 1 identifies these issues and reasons why they were not assessed.
Table 1 Environmental Issues Considered Not Relevant
Issue Reason for non - assessment
Air quality The development comprises of sealing and existing road. Air quality emissions are considered to be negligible.
Dust There are no sensitive receptors that will be impacted by the proposed works. It is assumed that Construction Environmental Management Plan will be produced to manage this issue.
Dieback Dieback is considered not to be an issue based on the location of the project area.
Noise and vibration
Visual amenity
Contaminated sites
Wiluna to Magellan Section
Noise and vibration are considered not to be an issue based on the lack of sensitive receptors in the project area.
Visual impact is considered to minimal.
The project area is isolated and is surrounded predominantly by pastoral leases. As the project comprises of sealing an existing road, it is unlikely that any contaminated sites exist in the project area.

2. Project Description and Justification
61/16529/52778
Main Roads has indicated that the Wiluna- Magellan section of the Goldfields
Highway is predominantly gravel and the development of the Magellan Minesite has increased the amount of traffic using the road. This has lead to an increase in
maintenance activities with a corresponding increase in costs. Main Roads WA is
proposing to seal a 30 km section of the highway from Wiluna to the minesite entrance.
It is proposed that roadworks will consist of subgrade preparation and basecourse
preparation using imported material from borrow pits. The potential basecourse pits
are located within 2 km of the existing road at 635 SLK (LHS) and between 613 and 618 SLK (both LHS and RHS). Borrow pits for subgrade are proposed to be located
within 500 m of the existing highway at an interval of 1 km.
It is also proposed to improve and/or construct drainage to the north of the existing road. The road will be built as low as practicable possibly to a level of 300 mm above
the existing ground level with multiple floodways to take sheet flow, especially at SLK 636-638.
Water will be sourced from a new bore located near the Magellan Minesite at 639.5 SLK RHS.
Concept design drawings are contained within Appendix A.

3. Environmental Impacts and Management
61/16529/52778
The following section identifies the environmental and social issues that are considered
to be relevant to the project, including descriptions of the existing environment.
Photographs of project site have been provided by Main Roads and they are shown in Appendix B.
3.1 Natural Environment
3.1.1 Climate
The closest meteorological station is located at Wiluna. The recorded climatic data is summarised as follows:
Wiluna Weather Station
Mean Annual Maximum Temperature Range
Mean Annual Minimum Temperature Range
Mean Annual Rainfall
Mean Annual Raindays per year
Mean Daily Evaporation
37.8 De (January) & 19.2 °e (July)
22.9 De (January) & 5.3 °e (July)
256mm
41.5
6.4mm
(Source -Bureau of Meteorology Climatic Averages of Australian Sites)
3.1.2 Geology and Soils
Marti nick McNulty Ply Ltd (1999) state that most of the study area is underlain by "Archaean gneiss and granite which is traversed by remnant belts of steeply dipping
metavolcanic greenstone and metasedimentary whitestone. The granitoids typically
form large monoliths or flat pavements, whereas the greenstones form elongate subdued hills and rugged strike ridges.
Most of the underlying bedrock, particularly along palaeodrainages, is obscured by alluvial, colluvial, aeolian and calcrete deposits. The thickness of these deposits varies
from a thin veneer to more than 20m.
Leached coarse grained red earths and red sands are the most extensive soils in the region and they are mainly derived from weathered rock on the old plateau. Shallow
red earths are widespread siliceous hard-pan (or Murchison Cement) occur on tributary
alluvial plains but the lower plains can also have calcareous and saline soils. Saline
soils have a powdery consistency due to dispersed carbonates, are brown in colour
and alkaline in nature. Shallow, stony soils are found extensively on hill slopes and
plateau surfaces and stone pavements are widespread even on lower soil covered slopes with leached soils.
Wituna to Magellan Section Preliminary Environmental Impact Assessement and Biological Survey

61/16529/52778
Within the study area, alluvial soils are typically restricted to valleys. Such valleys are
not common and consequently alluvial soils are not widespread in the study area and
the sands that characterise sand plains and Wanderrie banks".
3.1.3 Rivers, Wetlands and Drainage
The concept design drawings (refer Appendix A) indicate that West Creek is located at
622.5 SLK and a small, unnamed creek is located at 611.75 SLK. Main Roads WA is
also aware of possible sheet flow drainage between 636- 638 SLK. Please note that field investigation revealed that the section of road at West Creek is already sealed.
Recommendation 1:
It is recommended that Main Roads drainage design does not direct runoff towards the
creeks identified at 622.5 SLK and 611.75 SLK.
Recommendation 2:
It recommended that Main Roads design and construct the works to maintain existing
surface water drainage patterns.
Recommendation 3:
It is recommended that Main Roads design and construct the project with appropriate
erosion control measures to reduce the potential for scour.
3.1.4 Environmentally Sensitive Areas (ESA's)
The Department of Environment on-line database indicates that no ESA's will be
impacted by the proposed works.
3.1.5 Vegetation, Declared Rare and Priority Flora, Threatened Ecological Communities and Vegetation Clearing
Vegetation
Marti nick McNulty (1999) state that the project site is within the Austin Botanical District
(after Beard, 1990). The predominant vegetation is comprised of low woodlands and tall shrublands of Acacia aneura (Mulga) on red brown loams over siliceous hardpans,
and scattered shrub lands of Acacia aneura on gently undulating sandplains, and
mallee (Eucalyptus kingsmil/i) over hummock grasslands. In the vicinity of the Wiluna,
mosaics of woodlands of Acacia aneura and saltbush (Atriplex spp.) are common on
greenstone terrain.
Halosarcia spp. (samphire) and halophytic shrublands (Maireana and Scleroleana
spp.) occur in the low lying alluvial areas with saline soils and they are characterised
by chenopods, either as herbaceous shrubs in landscape units that have been stripped
of lateritised rock, leaving landforms of shallow stony plains and breakaways. Open
mulga with dense shrubs near drainage lines are also characteristic of the area.
Most communities have well developed shrub layers with various species of
Eremophila. Spinifex (mainly Triodia basedowit) forms the only extensive grassland,
with the annual grass Aristida arenaria and the perennial tussock grasses Danthonia
Wiluna to Magellan Section Preliminary Environmental Impact Assessement and Biological Survey

61/16529/52778
bipartita and Eragrostis lanipes also being common. After winter rains !orbs and
ephemerals, mostly composite, become short-lived elements of most plant
communities.
The effects of grazing by domestic and feral animals at levels which are not
sustainable, account for much of the soil and vegetation degradation that is evident in
the region.
Declared Rare and Priority Flora Species
The Department for Conservation and Land Management (CALM) was consulted to
determine the presence of any Declared Rare or Priority Flora Species that may exist in the project area. Table 1 indicates the results of the search and Table 2 provides a
description of the conservation codes.

X: Declared Rare Flora -Presumed Extinct Taxa
1: Priority One - Poorly known Taxa
2: Priority Two - Poorly Known Taxa
3: Priority Three - Poorly Known Taxa
Description
Taxa which have been adequately searched for and are deemed to be in the wild either rare, in danger of extinction, or otherwise in need of special protection, and have been gazetted as such.
Taxa which have not been collected, or otherwise verified, over the past 50 years despite thorough searching, or of which all known wild populations have been destroyed more recently, and have been gazetted as such.
Taxa which are known from one or a few (generally <5) populations which are under threat, either due to small population size, or being on lands under immediate threat, e.g. road verges, urban areas, farmland, active mineral leases, etc., or the plants are under threat, e.g. from disease, grazing by feral animals, etc. May include taxa with threatened populations on protected lands. Such taxa are under consideration for declaration as 'rare flora', but are in urgent need of further survey.
Taxa which are known from one or a few (generally <5) populations, at least some of which are not believed to be under immediate threat (i.e. not currently endangered). Such taxa are under consideration for declaration as 'rare flora', but are in urgent need of further survey
Taxa which are known from several populations, and the taxa are not believed to be under immediate threat (i.e. not currently endangered), either due to the number of known populations (generally >5), or known populations being large, and either widespread or protected. Such taxa are under consideration for declaration as 'rare flora' but are in need of further survey.
4: Priority Four- Rare Taxa Taxa which are considered to have been adequately surveyed and which, whilst being rare (in Australia), are not currently threatened by any identifiable factors. These taxa require monitoring every 5-10 years.
The geographical coordinates of the flora species have been plotted in Figure 1. It is
clear that none of the recorded flora species are within the study sites.

Weeds
Table 3 indicates the weed species that were identified by Martinick McNulty Ply Ltd in
1999. However, there are no widespread infestations of weeds within the study area.

Small stands of the troublesome weed Emex australis (doublegee) were found throughout the study area.
Further Works
As requested by CALM, a flora survey was completed on the 81h to gth of August 2005
(with a supplementary survey undertaken 291h August 2005), by a qualified botanist, to
determine the presence of declared rare or priority flora within the study sites. The flora and faun report is included at Appendix G and summarised in Section 4.
Recommendation 4:
It is recommended that Main Roads develop a Topsoil and Weed Management Program to minimise the spread of weed species during the construction of the project.
Clearing of Native Vegetation
Main Roads WA provided GHD with the proposed 13 borrow pit locations. It is
estimated that 59 hectares of vegetation will be removed as part of the development
based on the area of the borrow pits and a 2m widening of the road over 15km.
The Environment Branch of Main Roads WA has informed GHD that works associated with existing road developments are exempt from the Environmental Protection
(Clearing of Native Vegetation) Regulations 2004 until January 2006. Main Roads WA
has indicated clearing for stockpiles would occur between June and August 2005. However, if clearing is required after January 2006, a clearing permit under the
Environmental Protection (Clearing of Native Vegetation) Regulations 2004 may be
required.

61/16529/52778
3.1.6 Fauna
The Western Australian Museum's fauna database was accessed to determine the
likely presence of fauna in the study area. The results of database search are shown in Appendix D.
The Wildlife Conservation (Specifically Protected Fauna) Notice 2005 administered by
CALM was examined to identify any protected fauna that may be present in the study area. The Dasycercus cristicauda (Mulgara) was identified as Schedule 1 species
(fauna that is rare or likely to be extinct).
As this project is predominantly sealing an existing road, it is unlikely that Dasycercus cristicauda will be impacted.
The Commonwealth Department of Environment and Heritage's Matters of National
Environmental Significance database was accessed to determine the presence of any
fauna species that may impacted by the proposed works.
The search identified the following fauna species:
I Slender- billed Thornbill;
I Princess Parrot;
I Great Desert Skink;
I Oriental Plover;
I Fork -tailed Swift;
I Great Egret; and
I Rainbow Bee- eater.
The project consists of sealing an existing road. None of the above mentioned species should be impacted. Therefore referral to the Commonwealth under the Environmental
Protection and Biodiversity Conservation Act (1999) is not considered to be required.
Recommendation 6:
It is recommended that Main Roads WA ensure that Contractor's are aware of potential fauna in the project area. It is also recommended fauna management strategies
through normal Main Roads WA policies and standards be incorporated into the
contract documentation.
Wiluna to Magellan Section 10 Preliminary Environmental Impact Assessement and Biological Survey
4. Field Survey
61/16529/52778
As requested by CALM, surveys of the flora and vegetation in conjunction with an
opportunistic fauna survey within the proposed borrow pit and basecourse pit sites as well as 25m either side of the centreline of sections (618- 626 SLK and 636-647
SLK) were conducted by a qualified botanist and zoologist on the s'" and 91" of August
2005, and on the 291" August 2005 (Magellan Mine Intersection; 635.00 SLK).
Drainage, land use and landscape features were also noted at each site.
The vegetation and flora surveys recorded the vegetation types, species richness and
dominance. The surveys included a consideration of the presence of Declared Rare
Flora and Priority Flora and the condition and weed status of the vegetation was noted.
A list of species was generated for each pit site and road alignment sections.
The results of the Field Survey are located in Appendix G, and summarised below.
4.1 Vegetation
The predominant vegetation comprised of woodlands of Acacia aneura (Mulga), over
shrub layers of Eremophila species, Senna species and hummock grasses. Mulga
occurs with dense shrubs occurred near the drainage lines, with annual species
prevalent in these areas. Samphire communities occurred in low-lying alluvial areas with saline soils.
The vegetation condition was assessed in accordance with the Keighery (1994) Vegetation Condition Rating. A description of this rating scale is included in the field
survey report. The vegetation ranged from "Good to Excellent" condition, with most
areas in "Very Good" condition. Generally, the area exhibits soil and vegetation degradation from grazing by livestock and feral goats and previous land clearing
activities (including timber harvesting and small scale mining operations). There is little
evidence of weed invasion with only three species of weed recorded for the area.
4.1.1 Threatened Ecological Communities
No Threatened Ecological Communities were recorded from the survey.
4.2 Flora
A total of 110 taxa representing 36 families of flora were identified during the survey.
The families that were the most represented at the survey sites were:
• Asteraceae (daisies): 13 taxa
• Myoporaceae (poverty bushes): 12 taxa
• Poaceae (grasses): 10 taxa
• Mimosaceae (wattles): 9taxa,and
• Chenopodiaceae (saltbush, bluebush): Btaxa

61/16529/52778
4.2.1 Significant Flora
No Declared Rare or Priority Flora were recorded during the flora survey.
4.2.2 Weeds
Only three species are identified as an exotic or introduced/ornamental species:
Sonchus o/eraceus (Sowthistle), and two species of Cuscuta (Lesser Dodder). Sa/sola
kali (Roly poly) is a native species often described as a weed plant (Hussey eta/.,
1997), and was also located in this survey. None of the weed species recorded are
listed as Declared Plants by the Department of Agriculture.
Given the lack of weed species recorded from this flora survey, it is suggested that
hygiene practices be maintained to ensure that no other weeds and undesirable plant
species are introduced to the region. Given the remoteness of the location, the maintenance of a minimal weed presence through best practice procedures should be
relatively straightforward.
4.3 Site Survey Descriptions
The Site Descriptions, including vegetation types, condition, landscape features and potential impacts of basecourse or borrow pit activities is detailed in the Flora and
Fauna report attached at Appendix G.
4.4 Fauna
An opportunistic fauna survey was conducted in conjunction with the flora survey. In
total, 25 bird species, three mammal species and one reptile were observed. None of the species observed are considered as Rare of Priority species by CALM, or listed as significant under the Environmental Protection Biodiversity Conservation Act 1999.
4.5 Habitat Value
As individual sites, the development of the proposed basecourse pits will not impact severely on the existing animal habitat of the area. Due to a disruption in the natural
overland flow of water bringing nutrients to the grove, changes are likely for downslope mulga grove structure.

5. Social Environment
61/16529/52778
5.1.1 European and Natural Heritage
The databases of the Heritage Council of Western Australia and the Commonwealth's
Australian Heritage Place Inventory were accessed to determine the presence of any
European heritage sites that may be impacted by the proposed works.
No European heritage sites have been identified in the vicinity of the project area.
5.1.2 Aboriginal Heritage
An Aboriginal heritage field survey was not undertaken as part of this PEIA.
Investigations via the Department of Indigenous Affairs on-line databases determined
that ten Registered Aboriginal heritage sites are within five kilometres either side of the Goldfield's Highway (refer to Figure 1 ). A copy of the report is attached in Appendix F.
The Martinick McNulty report developed in 1999 indicates that seven sites were identified and that a Section 18 Clearance under the Aboriginal Heritage Act (1972)
should be obtained.
Subsequent work completed by Martinick McNulty {1999b) applied for the Section 18 Clearance, which was approved by the Department of Indigenous Affairs.
Correspondence in this regard is contained within Appendix C. However, it is not clear if borrow pits are covered under the Clearance.
Recommendation 5:
It is recommended that Main Roads adhere to the conditions placed under the Section 18 Clearance of the Aboriginal Heritage Act (1972), namely:
1 Main Roads W A fence those portions of sites 8036, 15815, 15817 that are not impacted by the proposed roadworks in order to avoid inadvertent damage;
1 Roadworks be confined to the areas covered by the existing road and road verges;
1 Movement and access by the workforce beyond the fenced area be prohibited and the workforce be instructed accordingly; and
1 It is also recommended that Main Roads confirm with the Department of Indigenous
Affairs whether borrow pits are also contained within the Section 18 Clearance.

61/16529/52778
5.1.3 Land Use
Martinick McNulty (1999) state that the dominant landuse in the study area is
agriculture, predominantly cattle, sheep and to a lesser extent goats. The road
traverses through six pastoral leases being:
1. Sherwod;
2. Killara;
3. Mooloogool;
4. Parco;
5. Lake Way; and
6. Millibillie.
Marti nick McNulty consulted with the landholders and the only concern was stock
losses due to damaged fences at Mooloogool Station.
The Department of Industry and Resources (DoiR) 'Tengraph' database was accessed to determine mining tenements in the project area.
The search revealed that five mining tenements may be impacted by the prosed works.
The tenements are:
I E53/1015;
I E53/111 0;
I M53/600;
I M53/1 003; and
I M53/78.
Recommendation 6:
It is recommended that Main Roads further consult with the pastoral lease holders prior to construction and recommend management actions to ensure that there are no stock
losses as part of the construction contract.
Recommendation 7:
It was recommended by DoiR that Main Roads liaise with mining tenement holders prior to the commencement of works.

61/16529/52778
5.2 Pre - construction and Construction Phase Impacts
Potential environmental and social impacts likely to require consideration during the
construction phase of the project include:
1 Damage to public property (particularly fencing);
1 Clearing;
1 Weeds;
1 Topsoil management;
1 Dust management;
1 Traffic safety and access;
1 Fire management;
1 Fuel and chemical storage; and
1 Rubbish disposal.
These issues will be managed through Main Roads construction phase environmental
management measures. The development of a construction phase Environmental
Management Plan, which addresses pre-construction issues will ensure the
implementation of all project specific environmental and social impact measures.
Recommendation 8:
It is recommended that standard Main Roads WA environmental management
standards be incorporated into contract documentation.

6. Consultation
61/16529/52778
As specified by Main Roads W A, no community consultation was undertaken.
However, GHD consulted with the Department of Agriculture, Department for Conservation and Land Management and the Department of Environment. A copy of
the correspondence received is contained within Appendix C.
Mr Jim Addison- Senior Technical Officer, Department of Agriculture (Kalgoorlie District Office).
The Department of Agriculture comments centre on any modifications to surface
hydrology created by the earthworks i.e.
1 Water deprivation of down-slope vegetation which may lead to death of
trees/shrubs;
1 Concentration of overland flows through culverts/floodways which might predispose down-slope soil surfaces to accelerated erosion; and
1 Department of Agriculture would expect the project to require clearing permits if
more than one hectare of vegetation is to be cleared. During that application process these surface hydrology issues may receive more attention.
Mr Brad Barton- Department of Conservation and Land Management (Goldfield Region).
1 A search of the CALM's Kalgoorlie Regional database also determined that the
Priority 1 species, Stackhousia c/ementii can be found along drainage lines;
1 There does not appear to be any known issues relating to restricted vegetation
community types that will be impacted by the project; and
1 A field survey by a suitably qualified botanist will be required to determine if any of
these species are likely to be disturbed during the completion of the project.
- A qualified GHD botanist and zoologist completed a flora and opportunistic
survey of the proposed borrow and base-course pit locations and sections of road upgrade on the 81
h and g'h of August 2005.
- A supplementary field survey was undertaken on the 291h August 2005.

61/16529/52778
Mr Tim Marelich- Department of Environment (Kalgoorlie Regional Office).
1 It is recommended by DoE that Main Roads WA consult the Environmental
Protection (Clearing of Native Vegetation) Regulations 2004 and provide some
explanation in the assessment as to which parts of the clearing are exempt from
requiring a permit and which parts may require a permit.
1 Dust generation is a potential issue of concern. Information should be provided on
the measures that will be put in place to control dust during construction activities.
1 A licence is required to extract groundwater in the Goldfields Groundwater Area. If water from road construction is to be extracted from Magellan's bore, a letter should
be provided by Magellan authorising the use of the water. It should also stipulate
the estimated quantity to be used. If the volume is significant enough a licence
amendment may be required.

7. Environmental Approvals
61/16529/52778
7.1 Commonwealth Approvals
No environmental impacts identified during the preparation of this PEIA warrant the
referral of the project to the Commonwealth Minister for the Environment under the provisions of the Environmental Protection and Biodiversity Conservation Act (1999).
7.2 Government of Western Australia
The Department of Environment (DoE) are responsible for administering the Environmental Protection Act (1986). This project consists of sealing an existing road.
This PEIA indicates that environmental and social impacts are minimal and formal
assessment by the DoE is considered not to be required.

8. Recommendations
61/16529/52778
Recommendation 1:
It is recommended that Main Roads drainage design does not direct runoff towards the
creeks identified at 622.5 SLK and 611.75 SLK.
Recommendation 2:
It recommended that Main Roads design and construct the works to maintain existing surface water drainage patterns.
Recommendation 3:
It is recommended that Main Roads design and construct the project with appropriate erosion control measures to reduce the potential for scour.
Recommendation 4:
It is recommended that Main Roads develop a Topsoil and Weed Management
Program to minimise the spread of weed species during the construction of the project.
Recommendation 5:
It is recommended that Main Roads adhere to the conditions placed under the Section 18 Clearance of the Aboriginal Heritage Act (1972), namely:
1 Main Roads WA fence those portions of sites 8036, 15815, 15817 that are not
impacted by the proposed roadworks in order to avoid inadvertent damage;
1 Roadworks be confined to the areas covered by the existing road and road verges; and
1 Movement and access by the workforce beyond the fenced area be prohibited and
the workforce be instructed accordingly.
1 It is also recommended that Main Roads confirm with the Department of Indigenous
Affairs whether borrow pits are also contained within the Section 18 Clearance.
Recommendation 6:
It is recommended that Main Roads further consult with the pastoral lease holders prior
to construction and recommend management actions to ensure that there are no stock losses as part of the construction contract.
Recommendation 7:
It was recommended by DoiR that Main Roads liaise with tenements holders prior to
the commencement of works.
Recommendation 8:
It is recommended that standard Main Roads WA environmental management
standards be incorporated into contract documentation.

Preliminary Environmental Impact Assessment Goldfields Highway (Wiluna to Magellan) and Coolgardie-Esperance Highway (Emu Rocks)
Thank you for your fax and subsequent email of the 8 June 2005 detailing the preliminary Environmental Impact Assessment for the above mention projects.
As explained to you during our telephone conversation on the same day the Department of Conservation and Land Management (CALM) has legislative responsibility in these areas with regard to the Conservation and Land Management Act 1984 and the Wildlife Conservation Act 1950.
CALM Goldfields Region has reviewed your documentation and information supplied by CALM's Wildlife Branch and provide the following comments;
• Wiluna
Eremophila congesta P I, Eremophilajlaccida subsp clementii PI, Ewy omyrtus injlata P l are all found within the local area and listed on Wildlife Branch's database search. The additional record of Stackhousia clementii P l (found along drainage lines) is recorded on our regional database.
There does not appear to be any known issues relating to restricted vegetation community types that will be impacted by this project.
Field surveys by a suitably qualified botanist will be required to determine if any of these species are likely to be disturbed during the completion of this project.

Goldfields-Esp H'way
Prostanthera splendens Pl, Philotheca apiculata P2 and Phebalium clavatum P2 are all known from the local area (and noted on our regional database and not Wildlife branch's database search) and if the project involves any areas around the margins of salt lakes then Halosarcia jlabelliformis P 1 and Pityrodia sp Yilgarn P3 need to be considered.
There does not appear to be any known restricted vegetation community types that occur in the area that this project will impact upon.
Field surveys by a suitably qualified botanist will be required to determine if any of these species are likely to be disturbed during the completion of this project.
The creation of a new borrow pit for earthworks and pavement material and access to a "naturally occurring ridge" as a gravel source for this project requires a floristic survey by a suitably qualified botanist to assess vegetation and floristics.
For all floristic surveys it is a requirement that voucher specimens be collected and submitted to the Western Australian Herbarium.
There are no known outbreaks of soil borne diseases (e.g. Dieback) in the Goldfields Region, however machinery should be cleaned of soil prior to transport to the work locations to reduce the risk of the spread of disease and weeds.
In general the activities do not impact on CALM estate and no issues should exist with minor widening of either area of road corridor.
Please contact Brad Barton at this office should you need additional information.
Yours faithfully

Andrew.
I have had a quick look at the proposal you forwarded to me on June 8th regarding the Goldfields Highway and Coolgardie-Esperance Highway Roadworks
Clearing of Native Vegetation
I believe that the main area of concern to the DoE based on the information you have provided is the clearing of native vegetation that is proposed to occur as part of the road widening and realignment activities as well as the borrow pit (section 1.3).
I suggest that you consult the Environmental Protection (Clearing of Native Vegetation) Regulations 2004 and provide some explanation in your assessment as to which parts of the clearing are exempt from requiring a permit and which parts may require a permit. If a permit is required it is good to get the application in early.
Dust
Dust generation is a potential issue of concern. Information should be provided on what measures will be put in place to control dust during construction activities. I am assuming the a portion of the water being used for construction will be used for dust suppression purposes.
Groundwater Extraction
A licence is required to extract groundwater in the Goldfields Groundwater Area. If water from road construction is to be extracted from Magellan's bore a letter should be provided by Magellan authorising the use of the water. It should also stipulate the estimated quantity to be used. If the volume is significant enough a licence amendment may be required.

Greetings Andrew Any concerns we might have would centre on any modifications to surface hydrology created by the earthworks. The two major issues are;
1. water privation of down-slope vegetation which may lead to death of trees/shrubs 2. concentration of overland flows through culvertslfloodways which might predispose down-slope soil surfaces to accelerated erosion
The Wiluna-Magellan project will be the more critical in these regards as landscapes in the area have relatively low water infiltration rates and can be subjected to intense summer storms.
I would expect both projects to require clearing permits if more than one hectare of vegetation is to be cleared. During that application process these surface hydrology issues would receive more attention.
I apologise for the brief nature of this response but time presses

61/16529/52778
Bush Forever Vegetation Condition Rating Scale {2000)
This scale recognises a level of intactness of vegetation which is defined by the
following:
1 completeness of structural levels;
1 extent of weed invasion;
1 historical disturbance from tracks and other clearing or dumping;
1 the potential for natural or assisted regeneration.
The scale therefore consists of six rating levels as below :
1. Pristine or nearly so. No obvious signs of disturbance.
2. Excellent. Vegetation structure intact, disturbance affecting individual
species, and weeds are non-aggressive species.
3. Very Good. Vegetation structure altered, obvious signs of disturbance.
4. Good. Vegetation structure significantly altered by very obvious signs of
multiple disturbance, retains basic vegetation structure or ability to
regenerate it.
5. Degraded. Basic vegetation structure severely impacted by disturbance.
Scope for regeneration but not to a state approaching good condition
without intensive management.
6. Completely degraded. The structure of the vegetation is no longer intact
and the area is completely or almost without native species.

1. Introduction
61/16529/54071
During the development of the Preliminary Environmental Impact Assessment (PEIA)
the Department of Conservation and Land Management requested flora and
opportunistic fauna surveys be undertaken for the proposed upgrade for the Wiluna to
Magellan Road. Main Roads Western Australia (Main Roads WA) commissioned GHD
to undertake a fiora and opportunistic fauna surveys within the proposed borrow pit and basecourse pit sites as well as 25 m either side of the centreline of sections (618-
626 SLK and 636-647 SLK). Surveys were conducted by a qualified botanist and zoologist on the 81
h and g'h of August 2005, and on the 291h August 2005 (Magellan
Mine Intersection; 635.00 SLK). Drainage, landuse and landscape features were also
noted at each site.
The vegetation and fiora surveys recorded the vegetation types, species richness and dominance. The surveys included a consideration of the presence of Declared Rare
Flora and Priority Flora and the condition and weed status of the vegetation was noted.
Goldfields Highway- Wllunna to Magellan Section Flora and Fauna Report
2. Vegetation
61/16529/54071
The vegetation was similar to that detailed by Martinick McNulty (1999) for the area.
The predominant vegetation comprised of woodlands of Acacia aneura (Mulga), over
shrub layers of Eremophila species, Senna species and hummock grasses. Mulga
occurs with dense shrubs occurred near the drainage lines, with annual species
prevalent in these areas. Sam ph ire communities occurred in low-lying alluvial areas
with saline soils.
The vegetatiqn condition was assessed in accordance with the Keighery (1994)
Vegetation Condition Rating. A description of this rating scale is included below. The vegetation ranged from "Good to Excellent" condition, with most areas in "Very Good"
condition. Generally, the area exhibits soil and vegetation degradation from grazing by livestock and feral goats and previous land clearing activities (including timber
harvesting and small scale mining operations). There is little evidence of weed
invasion with only three species of weed recorded for the area.
The vegetation and landscape features at each pit site and road alignment sections are
discussed in more detail below. Photographs of the pit site are located in Appendix A.
2.1 Vegetation Extent, Type and Status
A vegetation type is considered to be under-represented if there is less than 25 percent
of its original distribution remaining. Table 1 indicates the native vegetation types
represented at the site, their regional extent and reservation status as drawn from Shepherd eta/ (2002). None of the vegetation types recorded from the area are
under-represented.
Mulga woodlands and shrublands remain possibly the best represented of remnant
native vegetation communities. Much of this has to do with the fact that locations
where mulga is dominant species lies outside the Intensive Land-use Zone of Shepherd eta/ (2002). Mulga generally occurs in the pastoral regions of Western
Australia. While mulga communities will be impacted by livestock grazing and
movement, clearing for agricultural purposes is relatively minimal.
Mulga has been harvested in large volumes, particularly for use in the construction of
fencing. Such practices were observed scattered throughout the survey area, where
stumps of mulga trees harvested at some stage in the past.
The construction of basecourse pits will remove the entire vegetative communities
present at these sites.

Ecological communities are defined as 'naturally occurring biological assemblages that
occur in a particular type of habitat' (English and Blythe, 1997). Threatened Ecological
Communities {TECs) are ecological communities that have been assessed and
assigned to one of four categories related to the status of the threat to the community,
i.e. Presumed Totally Destroyed, Critically Endangered, Endangered, and Vulnerable.
Some TECs are protected under the Commonwealth Environmental Protection and Biodiversity Act, 1999 (EPBC Act). Although TECs are not formally protected under
the State Wildlife Conservation Act 1950, the loss of, or disturbance to, some TECs
trigger the EPBC Act. The Environmental Protection Authority's position on TECs states that proposals that result in the direct loss of TECs are likely to be formally
assessed.
No Threatened Ecological Communities were recorded from the survey in any of the basecourse pit, borrow pit or road alignment sections investigated.
2.3 Vegetation Condition
The vegetation at the study sites was given a condition rating based on the Keighery
Vegetation Condition Rating Scale (Keighery, 1994 ). The ratings in this scale are
described as follows:
Goldfields Highway~ Wilunna to Magellan Section Flora and Fauna Report

61/16529/54071
1. Pristine or nearly so.
2. Vegetation structure intact, disturbance affecting individual species, and weeds are
non-aggressive species.
3. Vegetation structure altered, obvious signs of disturbance.
4. Vegetation structure significantly altered by very obvious signs of multiple
disturbance, retains basic vegetation structure or ability to regenerate it.
5. Basic vegetation structure severely impacted by disturbance. Scope for
regeneration but not to a state approaching good condition without intensive
management.
6. The structure of the vegetation is no longer intact and the area is completely or
almost without native species.
Condition Ratings are allocated to each site examined in this survey.

3. Flora
61/16529/54071
Plants that could not be confidently named in the field were collected, pressed and
compared with Western Australian Herbarium specimens for formal identification. Collections of specimens that may have been Priority Species were made to ensure their correct identification. Plant specimens were also collected from the existing basecourse pits for an examination of likely colon ising species. Weed species (where present) were also collected to ensure correct identification and examined for their potential as Declared Plant species.
A list of all taxa collected and identified is provided in Appendix B. A total of 110 taxa representing 36 families of flora were identified during the survey. The final list is likely to be a reasonable reflection of plant species present, with annual species observed at
their flowering peak during the survey periods (August).
The families that were the most represented at the survey sites were:
J Asteraceae (daisies): 13 taxa
J Myoporaceae (poverty bushes): 12 taxa
J Poaceae (grasses): 1 o taxa
J Mimosaceae (wattles): 9 taxa, and
J Chenopodiaceae (saltbush, bluebush): 8 taxa
Individual genera were also dominant across the study sites, notably:
J Eremophila:
J Acacia:
J Senna:
J Plilotus:
12 recognisable taxa
9 recognisable taxa
6 recognisable taxa, and
5 recognisable taxa.
3.1 Significant Flora
No Declared Rare or Priority Flora were recorded during the flora survey.
3.2 Weed Species
Of the taxa recorded, only three species are identified as an exotic or introduced/ornamental species: Sonchus oleraceus (Sowthistle), and two species of Cuscuta (Lesser Dodder). Sa/sola kali (Roly poly) is a native species often described as a weed plant (Hussey et at., 1997), and was also located in this survey. None of the
weed species recorded in the Martinick McNulty survey were recorded in this survey.
Given the lack of weed species recorded from this flora survey, it is suggested that hygiene practices be maintained to ensure that no other weeds and undesirable plant species are introduced to the region. Given the remoteness of the location, the

maintenance of a minimal weed presence through best practice procedures should be
relatively straightforward.
3.2.1 Declared Weeds
Declared weeds are those which have been listed by the Department of Agriculture
under the Agriculture and Related Resources Protection Act (1972) as being of
particular significance, usually because of their risk to agriculture. If these species are present, the landowner or manager is required to carry out weed control to a specified
extent and to prevent the further spread or movement of them.
No Declared species were present in the study area.

5. Fauna
61/16529/54071
A field survey was carried out by qualified zoologist in conjunction with the flora survey
to examine the habitats present and their condition and to carry out an opportunistic survey of the fauna.
A full list of fauna observed can be found in Appendix C. In all, 25 bird species, 3
mammal species, no frog species and 1 reptile species were observed.
5.1 Expected Fauna
Western Australian Museum records indicate that 26 bird species, 10 mammal
species, 1 frog species and 43 reptile species have been observed in the vicinity of the
Goldfields Highway between Meekatharra and Wiluna. As the study areas are small (maximum 13 hectares) it is unlikely that any official WA Museum fauna surveys have
been specifically conducted for these sites.
Nomenclature
Field observations were undertaken using a range of references, and the nomenclature
for taxonomic orders and animal names was sourced on information provided by the
Western Australian Museum's online FaunaBase program (Western Australian Museum, 2005).
5.1.1 Significant Fauna
The conservation status of fauna species is assessed under State and Commonwealth
Acts; in particular the Wildlife Conservation Act 1 950; Wildlife Conservation (Specially
Protected Fauna) Notice 2003, and the Commonwealth Environmental Protection and Biodiversity Conservation (EPBC) Act 1999.
The significance levels for fauna used in the EPBC Act are those recommended by the
International Union for the Conservation of Nature and Natural Resources {IUCN) {Table 2).

Taxa whose survival depends upon ongoing conservation measures. Without these measures, a conservation dependent taxon would be classified as Vulnerable or more severely threatened.
Data Deficient (Insufficiently Know) Taxa suspected of being Rare, Vulnerable or Endangered, but whose true status cannot be determined without more information.
Least Concern Taxa that are not considered Threatened
Table 3 CALM Conservation Codes for Gazetted Fauna
Conservation Description Code
Schedule 1 " ... fauna that is rare or likely to become extinct, are declared to be fauna that is in need of special protection."
Schedule 2 " ... fauna that is presumed to be extinct, are declared to be fauna that is in need of special protection."
Schedule 3 " ... birds that are subject to an agreement between the governments of Australia and Japan relating to the protection of migratory birds and birds in danger of extinction, are declared to be fauna that is in need of special protection."
Schedule 4 " ... fauna that is in need of special protection, otherwise than for the reasons mentioned [in Schedule 1 - 3]"
In addition to these species with a formal gazetted conservation status (Table 3), the
CALM also maintains a Priority list of species that are restricted, vulnerable or too
poorly known to be considered for gazetting (Table 4). These species have no special
protection, but their presence would normally be considered. The taxon needs further
survey and evaluation of conservation status before consideration can be given to
declaration as threatened fauna. These may be trigger species in the Federal
Environmental Protection and Biodiversity Conservation (EPBC) Act 1999.

Table 4 Conservation Codes for Priority Fauna
Conservation Description Code
Priority 1 Taxa with few, poorly known populations on threatened lands.
Priority 2 Taxa with few, poorly known populations on conservation lands. Taxa which are known from few specimens or sight records from one or a few localities on lands not under immediate threat of habitat destruction or degradation, e.g. national parks, conservation parks, nature reserves, State forest, vacant Crown Land, water reserves, etc.
Priority 3 Taxa which are known from few specimens or sight records, some of which are on lands not under immediate threat of habitat destruction or degradation.
Priority 4 Rare taxa. Taxa which are considered to have been adequately surveyed and which, whilst being rare (in Australia), are not currently threatened by any identifiable factors. These taxa require monitoring every 5- 10 years.
Priority 5 Taxa in need of monitoring. Taxa which are not considered threatened but are subject to a specific conservation program, the cessation of which would result in the species becoming threatened within five years.
A listing of Rare and Priority species in the Department of Conservation and Land Management (CALM) rare fauna database for the general Meekatharra-Wiluna area was obtained {Table 5). This is combined with significant fauna species generate through an EPBC Act Protected Matters database search.

5.2 Observed Fauna
An opportunistic fauna survey was conducted in conjunction with the flora survey. In
total, 25 bird species, three mammal species and one reptile were observed. A fauna
list is attached in Appendix C. None of the species observed are considered as Rare
of Priority species by CALM, or listed as significant under the EPBC Act.
Two introduced species were observed, these were the European Rabbit and the Feral
Goat.
5.3 Habitat Value
All proposed sites for material extraction are located in slightly upland areas. No water
sources, natural or otherwise, were seen in the vicinity of the sites. Evidence exists that given enough rainfall, gullies and ephemeral creeklines adjacent to and running
through the sites would flow, and potentially hold water in small pools before
evaporating.
Goldfields Highway- Wilunna to Magellan Section Flora and Fauna Report

61/16529/54071
As individual sites, the development of the proposed basecourse pits will not impact
severely on the existing animal habitat of the area. Due to a disruption in the natural
overland flow of water bringing nutrients to the grove, changes are likely for downslope
mulga grove structure.
Also of note, at existing basecourse pits are a large number of reptile scratchings and
burrows present in piles of pushed up material. The reason for this is that the natural
soil condition of these areas is particularly stony, and burrowing activities through the
softer, pushed up material is easier for resident reptiles. While this report does not
advocate unnecessary disturbance of natural ground, it is interesting to note the
response by fauna to more advantageous conditions.
Similarly, the excavation of the basecourse pits will alter the natural runoff regimes of
the areas, increasing the pooling capacity of significant runoff, and providing a temporary water resource for local fauna populations.
