1. Introduction

1.1 BackgroundMain Roads Western Australia (Main Roads) has commissioned GHD Pty Ltd (GHD) tocomplete a desktop Preliminary Environmental Impact Assessment (PEIA) for theproposed reconstruction and geometric alteration on Muirs Highway. Main Roadsintend that these works will improve driver safety and in addition reduce maintenancerequirements. This report will be used in the environmental assessment and approvalsprocess and will assist in identifying the need for, and scope of, field investigations.The report will also provide a basis for discussion with environmental agencies aboutthe need to refer the proposal for statutory approval.

1.2 Scope of the ReportThe information in this report is based on existing database records, informationprovided by Main Roads and literature available in the public domain. The PEIA hasbeen prepared according to the scope given in Main Roads brief for the project thatincluded:

» Review of relevant environmental reports;

» Conduct an initial assessment of environmental aspects for the road proposal;

» Assessment of the project against the Environmental Protection Act’s 10 ClearingPrinciples (Schedule 5);

» Assessing all environmental aspects likely to require referral to the EnvironmentalProtection Authority (EPA);

» Assessing all matters of National Environmental Significance likely to requirereferral of the project and advise whether the project should be referred to theCommonwealth Department of the Environment and Water Resources (DEWR);

» Consultation with relevant government agencies as required;

» Determining (but do not applying for) clearances required under other legislativeprovisions, including (but not limited to) those required under the following Acts:

– Conservation and Land Management Act (1984);

– Wildlife Conservation Act (1950);

– Environmental Protection Act (1986);

– Rights in Water and Irrigation Act (1914);

– Heritage of Western Australia Act (1990); and

– Aboriginal Heritage Act (1972);

» A search of the Department of Environment and Conservation’s (DEC’s) DeclaredRare and Priority Flora database;

» A search of the DEC’s Threatened Ecological Communities (TEC’s) database;

» A search of the DEC’s Threatened Fauna database; and

» Prepare a concise report on the findings.

Based on the information provided by Main Roads and database/literature reviews, theenvironmental and social aspects considered and discussed in this PEIA include:

» climate;

» geology and soils;

» topography and hydrology;

» vegetation i.e. clearing and presence of Declared Rare or Priority Flora (DRF),Threatened Ecological Communities and the Commonwealth EnvironmentalProtection and Biodiversity Conservation Act (1999) (EPBC Act) listed species;

» weed management;


» fauna;

» indigenous heritage;

» nonindigenous heritage;

» land use; and

» construction phase impacts.

The Main Roads brief required a desktop investigation to assess a number of issues.However, some of these issues are considered to be not relevant to this study. Table1 identifies these issues and provides reasons why they were not assessed.

Table 1 Environmental Issues Not Relevant to the Proposed works

Issue Reason for non assessment

Contaminated sites A search of the DEC Contaminated Site Databaseidentified no reported contaminated sites in the Studyarea.

A review of current aerial photography did not identifyany existing potentially contaminating landuses. Thearea is used for agriculture and this is not typicallyconsidered a potentially contaminating landuse. It islikely the area has been used for agriculture for itsentire landuse history. It is also noted that the projectwill occur in the existing road reserve for with theexception of the 1.5km alignment east of the HaysRiver Bridge.

Public safety and risk Public safety and risk will be managed in accordancewith standard Main Roads WA specifications.

Vibration Noise and vibration are not considered to be an issuebased on the lack of sensitive receptors in the Projectarea. It is assumed that either a ConstructionEnvironmental Management Plan or Main Roadsspecifications will be developed to manage this issue inaccordance with Main Roads WA policies.


2. Project Description and Justification

Muirs Highway (M024) is a major route connecting the towns of Manjimup, MountBarker and, Denmark and the South Coast of Western Australia. The highway is beingused increasingly by heavy vehicles associated with forestry and viniculture, as well asby touring motorists. Forestry, viniculture and tourism are all developing industries inthe area and it is expected that traffic volumes on this section of road will increase inthe medium term. Main Roads has identified the need for improvements to enhanceroad user safety and reduce longterm maintenance costs on this important section ofroad.

The works will include reconstruction and geometric alterations to Muirs Highwaybetween SLK 149.15 and 157.31, beginning 5km west of the Mount Barker townshipincluding the matching in of both ends of the Hays River Bridge. An eastbound passinglane will be constructed at SLK 152 and intersections at EulupManurup Road, SaintWerburghs Road, Jones Road and Quangellup Road will be upgraded. The newalignment will be constructed adjacent to the existing alignment, 4 m to the south.There are currently two options for the horizontal geometric alterations and these aredescribed below.

Options

The positioning of alignment Options 1 and 2 are marked on Figure 2. Option 1 iscurrently preferred by Main Roads. The features of the upgrade for each alignment areidentical and there is no significant difference in the area of vegetation requiringclearing (Table 2). The only difference between the alignment options is the horizontalgeometric alteration between 152.30 and 154.9 SLK (Figure 2).

3. Previous Reports

The following reports provided by Main Roads were reviewed to obtain informationrelevant to this Project.

Halpern Glick Maunsell (2001) Mount Barker Bypass Environmental Assessmentand Management PlanAn Environmental Assessment and Management Plan (EAMP) was developed for theproposed Mount Barker Bypass. The project area for this EAMP is immediately west ofthe Project area for this current PEIA, and the study area extends across the westernextent of the existing and proposed alignments.

The main environmental and social issue related to the removal 1.5 ha of native vergeside vegetation and the isolation of 1.1 ha of remnant native vegetation from anadjacent Class A reserve.

GHD (2006) Mount Barker Northern Bypass Preliminary Environmental ImpactAssessment, March 2006

A PEIA was developed for the proposed construction of the Mount Barker NorthernBypass. The bypass was proposed to be 4.4 km in length, located north of MountBarker and linking the existing Muirs Highway west of the town (at 157.2 SLK) toAlbany Highway north of the townsite (at 161.4 SLK). The western extent of this projectarea immediately abuts the Project area for the current PEIA.

The main environmental and social issues identified included:

– The removal of vegetation from a Class A reserve;

– The removal of native vegetation that maintained less than 30% of its preEuropean extent; and

– The potential for impact upon two nonindigenous heritage sites.

Main Road additionally provided the below report, however, upon review it was notconsidered relevant to this PEIA:

GHD (2003) Muirs Highway Upgrade (Nyamup) 19.5 – 23.0 SLK Environmental ImpactAssessment and Environmental Management Plan.


4. Existing Environment

This section provides an account of the existing environment and potential impactsresulting from the Project as well as recommendations for further investigation ormanagement. Information used in this section has been sourced from previous reportsprovided by Main Roads, scientific literature, mapping, restricted and publicgovernment databases and consultation with State Government departments.

4.1 ClimateThe Site is subject to a temperate climate, experiencing mild to warm summers andcool winters (Commonwealth Bureau of Meteorology, 2004). Table 3 details the meantemperature ranges and rainfall data for the closest weather station to the Project area.

Mean Annual Rainfall 736.2 mm

Mean Annual Raindays per year 169.7 days

4.2 Topography, Hydrogeology and SoilsThe Project area is located within an area of undulating relief ranging fromapproximately 260 180 m Australian Height Datum (AHD) (Commonwealth ofAustralia, 1975). This landscape is characteristic of the Darling Range, within which theStudy area is located. Poor sandy soils and lateritic profiles are also a feature (Beard,1979).

The Western Australian Online Atlas indicates that Hay River is the main drainage linewithin at the Project area. Hay River flows southeast across the road alignment at 152SLK (refer to Figure 1) draining to the Wilson Inlet at Morley Beach. A second drainageline, Yamballup Creek, drains into the Hay River flowing adjacent to the existingalignment between 152.0 and 152.7 SLK.

As the road works will alter the topography of the land, disruptions to drainage patternsare likely. The impacts of this will be minimal however, if appropriate drainagemanagement measures are devised prior to the construction stage. Mr Kevin Shanhunof AgWest has confirmed this assessment (refer to Appendix A).


Ongerup Lagoon is an ephemeral lake located approximately 700m south of 150.2SLK. Reference to the Western Australian Online Atlas did not indicate any majordrainage lines flowing from the Project area to the lagoon. As in relation to Hay River,appropriate drainage management should be devised prior to the construction phase inorder to mitigate any potential impacts.

There is a low risk of accidental fuel and wastewater spills in the Project area and it isrecommended that pollution management actions be implemented in order to reducethis risk. This should include excluding plant and machinery laydown areas fromlocations likely to drain to the waterways present.

Recommendation 1Appropriate drainage management measures should be devised prior to theconstruction stage in order to avoid impacts from construction and new road surfacerunoff.

Recommendation 2

No laydown areas should be placed within 50m of the Hays River or Yamballup Creekin the Project area in order to reduce the risk of pollution from potential fuel, oil orwastewater spills.

Recommendation 3

Pollution management actions should be incorporated into Main Roads contractspecifications.

A desktop assessment of groundwater and topography in the Project area indicatesthat there could potentially be a risk of actual or potential acid sulphate soil conditionsoccurring along the both alignment options at the Hay River Crossing and YamballupCreek. These conditions have been experienced in Projects located in forested andagricultural areas of the Darling and Wicher ranges of South Western W.A.

Main Roads has informed GHD that the approaches to the bridge over the Hay Riverwill not be affected by the works (i.e. there will be no centreline shift). Therefore acidsulphate soils is not considered an issue if no excavations occur near the Hay Riverand Yamballup Creek.

The main environmental indicator is a shallow groundwater and/or waterlogging oflaterites and sands, which may have generated sulphidic conditions, which lead to acidsulphate soils. This is indicated by information obtained from the DoW relating to borestanding water levels (SWL) within 300 m of the Project area (Bore 20056790, SWL0.8m below ground level (BGL); Bore 20056791, SWL 1.8m BGL). A marking thelocations of these bores is included in Appendix B.


Recommendation 4In the event that excavations are required on the banks on the Hay River or YamballupCreek, a preliminary acid sulphate soil investigation should be undertaken in theexcavation area prior to works.

4.3 Environmentally Sensitive AreasThree Environmentally Sensitive Areas (ESAs) have been identified within the Studyarea Figure 1. The DEC database only contained type information relating to one of theidentified ESAs. The details obtained are documented in Table 4.

Table 4 Details of ESAs in the Study Area

Location Type of ESA

675m south of 151.1 SLK Class A Reserve

Ongerup Lagoon Nature Reserve

1980m east north east of 157.31 SLK Unknown, possibly related to DeclaredRare Flora

1980m east north east of 157.31 SLK Unknown

The Ongerup Lagoon Nature Reserve is located down slope of the Project area,however no major drainage lines flow from the Project area to the Reserve. There is alow risk of turbid runoff, fuel or wastewater spills reaching the area due to altereddrainage patterns if drainage is not managed. As per recommendations 0 and 0 thisrisk should be mitigated.

The two uncategorized ESAs identified are unlikely to be impacted given they arelocated almost 2 km up slope of the Project area (Table 4).

4.4 Reserves and Conservation AreasOne conservation reserve is located on the 675m south of 151.1 SLK, as described inSection 4.3.

DEC 50.5073ha

It is not expected that the Ongerup Lagoon Nature Reserve will be impacted by eitherproposed alignment. This issue is discussed in Section 4.3.


4.5 Vegetation and Flora

4.5.1 Vegetation

General information on the vegetation of the Mount Barker area has been obtainedfrom Beard (1979), The Vegetation of the Albany and Mount Barker areas, WesternAustralia: Map and Explanatory Memoir 1:250 000 Series. The Site is located withinthe Darling Botanical District of the Narrikup Vegetation System. Prior to clearing forEuropean settlement this area would have been characterised by continuous JarrahMarri forest association. Review of current aerial photography indicates that the areahas been extensively cleared, with only patches and corridors of vegetation remaining.

Shepherd et al (2002) assessed the area of remnant vegetation associations ofWestern Australia in terms of the preEuropean vegetation cover. According toShepherd, et al. (2002), the vegetation of the project area represents a Medium Forestof JarrahMarri, and is best described by Vegetation Association No. 3. This translatesto the following extent and status information:

Table 6 Vegetation Extent and Status Data for Project area

Shepherd Vegetation Extent Data Project Area

PreEuropean extent (ha) 3 046 385 hectares

Current remaining extent (ha) 2 197 837 hectares

Remaining (%) 72.1 %

Remaining in Reserves (%) 67.9 %

Source: Shepherd et al (2002)

As greater than 30% of the present vegetation type is contained in reserves, vegetationextent should not pose a constraint to the Project.

4.5.2 Declared Rare and Priority Flora

Significant impacts on species of flora that are listed as rare or endangered under theCommonwealth Environmental Protection and Biodiversity Conservation Act 1999 (CthEPBC) can trigger referral of development proposals to the CommonwealthDepartment of Environment and Water Resources (DEWR). A search of the Cth EPBCAct Protection Matters database identified no Threatened flora species within the Studyarea.

In addition to listing under the Cth EPBC Act, significant flora in Western Australian areprotected under the Wildlife Conservation Act (1950), which is administered by theDEC and specifically protects Declared Rare Flora (DRF) species and Priority ListedFlora (PLF) species. A search of DEC databases has identified four species of DRFand twentyfour PLF could potentially occur in the Project area. These are tabulated inAppendix C along with definitions for the assigned conservation codes.


4.5.3 Threatened Ecological Communities

A search of the DEC Threatened Ecological Communities (TEC’s) database did notidentify any TEC’s within the Project area.

4.5.4 Dieback

The Study area is located within an area conducive to Dieback infection. Dieback isfound throughout the southern extent of Western Australia in areas with susceptibleplant species that receive rainfall in excess of 400mm/year (Dieback Working Group,2005).

Recommendation 5

Develop Dieback hygiene procedures as prior to construction works. The proceduresshould include liaison with the DEC to source any fill to ensure that it is deemed to befree of Dieback.

4.5.5 Weed Management

As survey documented in Halpern Glick Maunsell (2001), indicates that a number ofweed species could potentially occur in the Study area.

The Class A reserve, Ongerup Lagoon Nature reserve is located 675m from theexisting road reserve and there is currently a linkage between the two. Weed spreadthrough human, machinery, soil and runoff vector will need to be managed to ensurethe reserve is not compromised by weed invasion.

Recommendation 6

Main Roads should develop Weed hygiene procedures and include them as part oftheir contract specifications.

4.6 Clearing of Native VegetationIt is estimated that approximately 16.3 ha of native vegetation will be required to beremoved in the Project area. This applies to both alignment options. Table 8 providesdetails on a desktop assessment of the Project works (including both alignmentoptions) against the DEC 10 Clearing Principles associated with the EnvironmentalProtection (Clearing of Native Vegetation) Regulations 2004.

Table 8 Assessment Against the Ten Clearing Principles: Project area

Clearing Principle Does VarianceOccur

Comment

It comprises a high level ofbiological diversity.

Proposal is notat variance withthis principle.

The Narrikup area within which the areasof interest lie is not listed as a NationalBiodiversity Hotspot.

It comprises the whole or apart of, or is necessary forthe maintenance of, asignificant habitat for faunaindigenous to WesternAustralia.

Not likely to beat variance withthis principle.

The closest conservation reserve islocated 675m away and a vegetation linkis located along a proposed spoon drainat 151.45 SLK. This could potentially forma fauna corridor for passage between theHay Rive, Road reserve and conservationreserve. A vegetation, flora and faunasurvey will be required to investigate thisissue further.

It includes, or is necessaryfor the continued existenceof, rare flora.


A desktop assessment has identified thatthe Study area DRF, although none hasbeen previously identified in the areas tobe cleared. A vegetation, flora and faunasurvey will be required to investigate thisissue further.

It comprises the whole or inpart of, or is necessary forthe maintenance of, athreatened ecologicalcommunity.


No TEC’s have been recorded within anarea that may be affected by theproposed works area.

It is significant as a remnantof native vegetation in anarea that has beenextensively cleared.


Refer to Section 4.5.1


Clearing Principle Does VarianceOccur

Comment

It is growing in, or inassociation with, anenvironment associated witha watercourse or wetland.


Main Roads has informed GHD that norealignment work will be done near theHay River Bridge. Therefore, novegetation will be impacted.

The clearing of thevegetation is likely to causeappreciable landdegradation.


Assuming effective measures can bedevised and implemented to controlconstruction and road runoff, it is notexpected that appreciable landdegradation effects will occur. If effectivemeasures cannot be devised thisassessment will need to be reviewed.

The clearing of thevegetation is likely to havean impact on theenvironmental values of anyadjacent or nearbyconservation area.


The closest conservation reserve islocated 675m away. A vegetation link tothe reserve is located along a proposedspoon drain at 151.45 SLK. Weed anddieback infestation could be an issue ifnot appropriately managed. A vegetation,flora and fauna survey will be required toinvestigate this issue further.

The clearing of thevegetation is likely to causedeterioration in the quality ofsurface or undergroundwater?


Main Roads WA will ensure that there isno deterioration in surface or undergroundwater quality by implementing anappropriate and effective managementplan.

The clearing of thevegetation is likely to cause,or exacerbate, the incidenceor intensity of flooding.


Main Roads WA will ensure that there isno deterioration in surface or undergroundwater quality by implementing anappropriate and effective drainagemanagement.

This project does not appear to be at variance with the 10 clearing principles.

Recommendation 7

A vegetation, flora and fauna survey to confirm whether the Project will be at variancewith regard to impacts on indigenous fauna, DRF, impacts on conservation reserves.


4.7 FaunaThe conservation of fauna species and current significance status is assessed underState and Commonwealth Acts. The acts include the Western Australian WildlifeConservation Act 1950; Wildlife Conservation (Specially Protected Fauna) Notice2003, and the Cth EPBC Act.

The DEWR maintains a database of matters of national environmental significance thatare protected under the Cth EPBC Act. A Cth EPBC Act Protected Matters Report wasgenerated (from the website of the DEWR), for the matters of significance that mayoccur in, or may relate to, the Study area. The search did not identify any Threatened,Migratory Territorial, Migratory Marine and other protected species within the Studyarea. Appendix G contains the results of the EPBC Act search.

A search of the DEC’s Threatened fauna database for any rare and priority speciesthat may occur in the vicinity of the Study area was undertaken. Three Schedule 1species and two Priority species were identified (Table 9). Table 10 contains WesternAustralian significant fauna classification definitions. Appendix D contains the listprovided by the DEC.

Schedule 3 “… birds that are subject to an agreement between thegovernments of Australia and Japan relating to the protection ofmigratory birds and birds in danger of extinction, are declared tobe fauna that is in need of special protection.”

Schedule 4 “… fauna that is in need of special protection, otherwise than forthe reasons mentioned [in Schedule 1 – 3]”

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 fromone or a few localities on lands not under immediate threat ofhabitat destruction or degradation, e.g. national parks,conservation parks, nature reserves, State forest, vacant CrownLand, 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 ofhabitat destruction or degradation.

Priority 4 Rare taxa. Taxa which are considered to have been adequatelySurveyed and which, whilst being rare (in Australia), are notcurrently threatened by any identifiable factors. These taxarequire monitoring every 5 – 10 years.

Priority 5 Taxa in need of monitoring. Taxa which are not consideredthreatened but are subject to a specific conservation program,the cessation of which would result in the species becomingthreatened within five years.

Information from the Main Roads documented in the Consultant Brief, indicates that anumber of mature vegetation and some large trees are present along the road reserve.These could provide good quality habitat vegetation for local fauna.

A vegetation linkage between the road reserve and the Class A Ongerup LagoonNature Reserve at 151.45 SLK, along the proposed spoon drain for both alignmentoptions. This could provide part of a corridor for fauna to travel between the Hay Riverand the reserve.


Recommendation 8A vegetation, flora and fauna survey should be carried out within the Study area toallow a more informed assessment of the potential impacts of the Project on localfauna.

4.8 LanduseReference to the Plantagenet Town Planning Scheme No. 1 indicates that the Projectarea is zoned rural. This indicates that the road reserve is likely to be surrounded byagricultural land. It is clear from communication with Main Roads that the alignmentoption 1 will extend outside of the road alignment. Appendix E contains certificate oftitle for the land it protrudes onto.

Recommendation 9If the chosen alignment protrudes outside of the existing road reserve, Main Roadsshould liase with the impacted land owner to determine the acceptability of thealignment position.

The DEC Native Vegetation map viewer indicates that the Project area is located on amining tenement (E70/3139) held by Great Southern Gold Pty Ltd.

Recommendation 10

If the chosen alignment protrudes outside of the existing road reserve, Main Roadsshould liase with DoIR and Great Southern Gold Pty Ltd to determine the acceptabilityof the alignment position.


4.9 Heritage

4.9.1 Indigenous Australian Heritage

A search of the Department of Indigenous Affairs (DIA) Aboriginal Heritage InquirySystem identified three Indigenous heritage sites in the Study area. The details ofthese sites are summarised in Table 11.

Immediately south of the Study area is a further 18 artefact/ scatter sites.

Recommendation 11Main Roads should contact the DIA to determine the survey area extent for the foursurveys that identified Sites 15089, 15090 and 15093. If the surveys include theProject area, no further action is required. If the surveys do not cover the Project area,an archaeological and ethnographic survey should be completed prior to theconstruction stage to identify any further sites.

Given the place is located approximately 6 km from the Project area, it is notanticpiated that it will be impacted by the proposed works.

A search of Western Australian Heritage Council’s Heritage Places Database, identifedtwo hertiage places located on Muir Highway. The places are listed in the PlantagenetMunicipal Inventory. The details obtained from the search are summarised in Table 14.The exact location of the places has not been provided.

Recommendation 12Main Roads should consult with the Shire of Plantagenet office to determine thelocation of the Langton and Merryup homesteads in relation to the Project area. Oncethe location is known, an assessment should be made regarding the potential impactsfrom the proposed works.

4.10 Construction Phase ImpactsPotential environmental and social impacts likely to require consideration during theconstruction phase of the Project include:

» clearing;

» weeds;

» traffic safety and access;

» fire management;

» pollution management; and

» rubbish disposal.

These issues will be managed through the implementation of a construction phaseEnvironmental Management Plan (CEMP) and/ or Main Roads WA standardcontractual documentation.


5. Consultation

This section provides an account of the consultations undertaken with governmentdepartments and authorities regarding the potential impact of the project on theexisting environment. This information is incorporated in the assessment of potentialenvironmental impacts conducted in Section 4.

GHD undertook consultations with representatives from DEC, the Department of Foodand Agriculture (AgWest) and the Department of Water (DoW) via email and writtencorrespondence. The subject of these consultations is provided below.

» AgWest, Albany Office – Mr. Kevin Shanhun (Line Manager/Senior LandConservation Officer): Consultation regarding drainage and tree removal.

» DEC, South Coast Region – Mr Lawrie Anderson (Natural Resource ManagementOfficer): Consultation regarding vegetation impacts and declared rare floralocations. It was noted that Hay River forms the boundary between the jurisdictionsof the DEC South Coast (east) and Warren Regions. Time constraints did not allowfor consultation with the Warren Region DEC Office.

Ms Marissa Paplia of the Albany DoW Office was contacted in writing with regard tothe presence of any significant wetlands in the Study area. A response was notreceived prior to the report’s completion.

Appendix A contains copies of the full correspondence.


6. Environmental Approvals

The Existing Environment analysis in Section 4 has enabled GHD to recommendwhether Commonwealth or State approvals are required for this Project. This isoutlined under the following subheadings.

6.1 Commonwealth ApprovalsNo environmental impacts identified during the preparation of this PEIA warrant referralof the project to the Commonwealth under the provisions of the EnvironmentalProtection and Biodiversity Conservation Act (1999).

6.2 Western Australian ApprovalsThe DEC is responsible for administering the Environmental Protection Act (1986).This PEIA indicates that environmental and social impacts of the Project are likely tobe minimal and as such, formal assessment by the DEC and EPA is considered not tobe required.

Based upon available information, this project is unlikely to be at variance to any of theClearing Principles, therefore it will be able to be delivered using Main Roads State –Wide Purpose Clearing Permit (818/3).

A vegetation, flora and fauna survey will need to be conducted to determine the toconfirm whether the Project will be at variance with the 9 clearing principles, withregard to impacts on indigenous fauna, DRF, impacts on conservation reserves.

In addition, Main Roads should consult with the DEC regarding the acceptability ofvegetation removal along the Hay River for the proposed works.


7. Conclusions and Recommendations

The desktop assessment and review undertaken as part of this PEIA indicates thatthere is a low level of potential environmental and social impacts associated with theupgrade and realignment of Muir Highway between 149.15 and 157.31 SLK.

GHD had provided the following recommendations throughout this report to ensure thatthe proposed works occur with least possible impact on the immediate and surroundinghuman and natural environment:

» Appropriate drainage management measures should be devised prior to theconstruction stage in order to avoid impacts from construction and new road surfacerunoff;

» No laydown areas should be placed within 50m of the Hays River or YamballupCreek in the Project area in order to reduce the risk of pollution from potential fuel,oil or wastewater spills;

» Pollution management actions should be incorporated into Main Roads contractspecifications;

» In the event that excavations are required on the banks on the Hay River orYamballup Creek, a preliminary acid sulphate soil investigation should beundertaken in the excavation area prior to works;

» Develop Dieback hygiene procedures as prior to construction works. Theprocedures should include liaison with the DEC to source any fill to ensure that it isdeemed to be free of Dieback;

» Main Roads should develop Weed hygiene procedures and include them as part oftheir contract specifications;

» A vegetation, flora and fauna survey to confirm whether the Project will be atvariance with regard to impacts on indigenous fauna, DRF, impacts on conservationreserves;

» A vegetation, flora and fauna survey should be carried out within the Study area toallow a more informed assessment of the potential impacts of the Project on localfauna;

» If the chosen alignment protrudes outside of the existing road reserve, Main Roadsshould liase with the impacted land owner to determine the acceptability of thealignment position;

» If the chosen alignment protrudes outside of the existing road reserve, Main Roadsshould liase with DoIR and Great Southern Gold Pty Ltd to determine theacceptability of the alignment position;

» Main Roads should contact the DIA to determine the survey area extent for the foursurveys that identified Sites 15089, 15090 and 15093. If the surveys include theProject area, no further action is required. If the surveys do not cover the Project


area, an archaeological and ethnographic survey should be completed prior to theconstruction stage to identify any further sites; and

» Main Roads should consult with the Shire of Plantagenet office to determine thelocation of the Langton and Merryup homesteads in relation to the Project area.Once the location is known, an assessment should be made regarding the potentialimpacts from the proposed works.

Joanne,My comment and advice is as follows:

1. Bennett Rd/Chester Pass Rd junctionNo issues with DRF/Priority flora at this site.There will obviously be some small amount of native vegetation that willbe cleared with either option A or B. MR WA has a purpose permit thatmay cover this clearing. Please check to ensure this clearing iscovered. Determine the area of native vegetation that will be clearedwith either option and calculate the area of the conservation offsetthat may be required if the clearing proceeds. MR WA will need to agreeto undertake the conservation offset proposed ie revegetate anappropriate area of road verge at this or another similar site nearby.Drainage issues probably exist already will roadside runoff enteringthe wetland on the private land to the west of the junction. I’m notcertain how this can be avoided since the site occurs in a naturalbasin. The wetland is grossly degraded from livestock access that hasoccurred over a long period.

2.Muir’s Highway west of Mount BarkerDEC Albany District has a record of DRF Caladenia christineae on AclassReserve 27183, but the occurrence is located uphill and away from wherethe Muirs Highway works are planned. This occurrence should be on theDEC DRF database but if further details are required, contact Dr SarahBarrett DEC Albany on 98424521. It is considered that the site will notbe impacted by the proposed works, particularly if vehicle/machineaccess and movement is restricted in the reserve. Comments regardingclearing as expressed above in 1. are also applicable to this project.It should also be noted that the boundary between DEC South Coast Regionand DEC Warren Region is the Hay River, consequently any commentsregarding this project that occurs west of the Muirs Highway crossingover the Hay River should be sought from Karlene Bain, DEC FranklandDistrict (which is part of DEC Warren Region).Regards,Lawrie Anderson

Dear Lawrie,

Following discussion with one of your collegue yesterday afternoon i wasinstructed to pass this referral onto you for comment.

My collegue and I would like your assistance with two Main Roads WA,Preliminary Environmental Impact Assessments (PEIA). It is part of ourscope of work to consult with relevant government agencies, including DECand we appreciate your time helping us with this matter.

I have attached information on the projects below, if you require anyfurther information please contact me at your convienence.

1. The first project is associated with the upgrade of Bennett Roadintersection, 30km north of Albany on Chester Pass Road.The project specifically entails:> Three proposed upgrade options, two of which will result in therepositioning of the intersection further south,> While the third option will consist of geometric alterations(horizontal) i.e. flattening of the road surface north and south of theexisting intersection; and> additional seal width at the upgraded intersection,

The road works are likely to require clearing of a small stand ofvegetation along the Bennett Road road reserve (20 m wide) and within thecleared paddock (Option A and B)(refer to aerial photo attached). Howeverthere are no Threatened Ecological Communities within the study area.Could you please provide comments on any concerns of DEC, i.e. potentialimpacts on drainage, DRF and vegetation clearing.

2. The works relating to this project are to be undertaken on a section ofMuirs Road east of Mount Barker. The study area is shown in the Attachmentbelow.

The works include the following:> the shifting of the existing road alignment to eliminate horizontalcurves in the road. In addition, the entire road is proposed to be shifted



4m to the south;> the adjustment of vertical curves (i.e. hills and valleys on theroad)> widening of the sealed portion of the road; and> the addition of a passing lane for eastern bound traffic.

The existing road reserve is 30m wide and most of the proposed works willbe contained within this area. The section requiring horizontal curveelimination will protrude onto the Martin's Pastoral lease north of MuirsRoad and Main Roads WA are currently under negotiations on this matter. Anumber of mature trees are located on the road reserve close to theexisting carriage way. It is percieved that some of these will need to beremoved for the works. An intitial estimate for the total area requiringclearing is approximately 10 ha. The existing and proposed alignmentbridges Hays River.

The deadline for these reports is Friday this week, if you are able toprovide comments by then that would be greatly appreciated.

Thanks again for your time.

Hi Joanne

I have inspected the sites of planned roadwork as presented and make the following comments forconsideration:

PROPOSED WORKS ON CHESTER PASS ROAD, ADJACENT TO BENNETT ROAD

• The three options presented for this area have been discussed with the landholdersadjacent to where the roadwork is planned.

• The overwhelming response from them was in support of Option C, that is, to cutand fill on Chester Pass Road. The fill to be to be placed north and south of theexisting crest area to improve road vision.

• Options A & B would result in increased dust for the existing house and thecreation of a small but useless parcel of land without water.

• There appears to be an increase in heavy haulage vehicles entering Chester PassRoad from Bennett Road and heading south towards Albany. Log haulage fromplantations in the areas east of Chester Pass Road are a significant factor in theincrease. It was suggested that a slip type access be formed to allow trucks exitingBennett Road to keep out of the main traffic flow path south and merge onto ChesterPass Road once they had gained speed and it was safe to enter. At the moment, allvehicles have to stop and then go directly onto Chester Pass road when heading south.This is extremely risky as road trains using Chester Pass Road and heading south haveno chance of stopping before Bennett Road. Locals gave me plenty of examples of"near misses" and there has been a need to have someone north of Bennett Roadchecking on oncoming traffic to confirm whether it was safe to exit Bennett Road.Radios for contact between trucks and support vehicles have also been used for safetypurposes.

• As part of the cut and fill option, landholders adjacent to that area indicated thataccess into their properties needed to be wide enough to allow semitrailers to negotiateentry from Chester Pass Road.

• The landholder immediately to the west of Chester Pass Road has property accessjust south of Bennett road on the opposite side of Chester Pass Road. The problemwith that access is similar to the Bennett Road access, but obviously doesn't carry somuch traffic. There is no option to shift that entry further south as the area becomesflooded in winter and the property boundary is not far away. The landholder suggestedthat, for safety purposes shifting that entry to the north would be a much saferproposition and one that should be considered. Opportunity exists to negotiate anddiscussion is recommended.

• No issues with drainage/water management if roadwork proceeds, providedconsideration is given to safe disposal of runoff.

PROPOSED WORKS ON MUIRS HIGHWAY, WEST OF MT BARKER

• There are a number of large trees to be removed, so compliance (assessment andapproval) needs to be considered.

• No issues with drainage/water management if roadwork proceeds, provided consideration isgiven to safe disposal of runoff.

Dear Kevin,

As discussed yesterday afternoon, my collegue and I would like youassistance with twoMain Roads WA, Preliminary Environmental Impact Assessments (PEIA). It ispart of our scope of work to consult with relevant government agencies,including Ag West and we appreciate your time helping us with this matter.

Conservation Code Description

R: Declared Rare Flora –Extant Taxa

Taxa which have been adequately searched for and aredeemed to be in the wild either rare, in danger ofextinction, or otherwise in need of special protection,and have been gazetted as such.

P1: Priority One – PoorlyKnown Taxa

Taxa which are known from one or a few (generally <5)populations which are under threat, either due to smallpopulation size, or being on lands under immediatethreat, e.g. road verges, urban areas, farmland, activemineral leases, etc., or the plants are under threat, e.g.from disease, grazing by feral animals etc. May includetaxa with threatened populations on protected lands.Such taxa are under consideration for declaration as‘rare flora’, but are in urgent need of further Survey.

P2: Priority Two – PoorlyKnown Taxa

Taxa which are known from one or a few (generally<5)populations, at least some of which are not believed tobe under immediate threat (i.e. not currentlyendangered). Such taxa are under consideration fordeclaration as ‘rare flora’, but are in urgent need offurther Survey.

P3: Priority Three – PoorlyKnown Taxa

Taxa which are known from several populations, and thetaxa are not believed to be under immediate threat (i.e.not currently endangered), either due to the number ofknown populations (generally >5), or known populationsbeing large, and either widespread or protected. Suchtaxa are under consideration for declaration as ‘rareflora’ but are in need of further Survey.

P4: Priority Four – Taxa inneed of monitoring

Taxa which are considered to have been adequatelySurveyed and which, whilst being rare (in Australia), arenot currently threatened by any identifiable factors.These taxa require monitoring every 5 – 10 years.
