Dear Robert

DEVELOPMENT APPLICATION AND EXTRACTIVE INDUSTRY LICENCE APPLICATION - LOT 371 HOPELAND ROAD, HOPELAND

Goodfeel Enterprises Pty Ltd (Goodfeel) proposes to extract sand from Lot 371 (No. 514) Hopeland Road, Hopeland (referred to as 'the site'). Recently, the Shire of Serpentine-Jarrahdale contacted (Goodfeel) about preliminary activities within the site related to the extraction of sand. No sand has been extracted from the site since correspondence was received from the Shire of Serpentine-Jarrahdale, with all plant and equipment removed from the site

Goodfeel engaged Emerge Associates to provide consultancy services to support the preparation of a Development Approval (DA) and Extractive Industry Licence (EIL) application to facilitate the extraction of the sand resource within the site. The site is zoned 'Rural' under the Metropolitan Region Scheme (MRS) and 'Rural' under the Shire of Serpentine-Jarrahdale Town Planning Scheme (TPS) No. 2. Under the 'Rural' zone, sand extraction is considered to be 'Industry-Extractive' and is a discretionary land use in 'Rural' zoned areas.

The supporting documentation has been prepared in accordance with the Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999 and Info Note PS06 - Guidelines for Extractive Industries. Table 1 of the document outlines the specific criteria outlined within the local law and where these have been addressed within the application package. This information has also been provided in Attachment 1. The enclosed information is intended to support the application process and has been prepared to outline:

• The planning context and the environmental attributes and values associated with the site.

• The proposed sand extraction process.

• Management of potential impacts associated with the proposed sand extraction.

• Decommissioning and rehabilitation following extraction of the sand resource.

Overall, the proposed extraction of sand meets the broader land use considerations of the Western Australian Planning Commission (WAPC) and the Shire of Serpentine-Jarrahdale, by maximising the use of the sand resource, while ensuring that the sand extraction operation will not impact adversely on the environment or amenity of surrounding landholdings. Section 4 and Section 6 of the

supporting document provide detail on the environmental attributes and values identified within the

site, and how the proposed sand extraction within the site will be managed.

The proposed sand extraction is unlikely to significantly impact environmental attributes or values, or

nearby land uses as:

• The site is currently cleared of intact remnant vegetation and largely composed of grazed paddocks. A number of remnant native trees species will be cleared, however these trees do not form areas of intact remnant vegetation nor are they utilised significantly by conservation significant fauna.

• The current hydrological functions of the site will be maintained, primarily through limiting the vertical extent of sand extraction. This includes providing at least one metre separation between the determined AAMGL and the post extraction ground surface.

• It is located within an area designated for poultry farms, with horse agistment, grazing and poultry farming the predominant land uses within the broader area. The proposed sand extraction is not expected to impact nearby sensitive land uses to a greater extent than the poultry farms in the broader area.

The DA and EIL application have been attached for your consideration and review. We have included three hard copies of the document and all technical appendices along with a CD containing an electronic version for your information.

Should you have any queries regarding the content of the attached management plan, please do not

hesitate to contact me on (08) 9380 4988.

Executive Summary

Goodfeel Enterprises Pty Ltd (Goodfeel) proposes to extract sand from Lot 371 (No. 514) Hopeland Road, Hopeland (referred to as ‘the site’). The proposed sand extraction is intended to supply a critical basic raw material that will be used for a variety of purposes such as clean fill sand and construction sand, to support infrastructure and urban development throughout the broader region. Depending upon demand, it is estimated that the sand resource will support mining for five to 10 years within the site.

The site is zoned ‘Rural’ under the Metropolitan Region Scheme (MRS) and ‘Rural’ under the Shire of Serpentine-Jarrahdale Town Planning Scheme (TPS) No. 2. It is also located within the ‘Poultry Farm Special Control Area’ under Shire of Serpentine-Jarrahdale TPS No. 2. Under the ‘Rural’ zone, sand extraction is considered to be ‘Industry-Extractive’ and is a discretionary land use in ‘Rural’ zoned areas.

Emerge Associates have been engaged by Goodfeel to provide consultancy services to support the preparation of a Development Approval (DA) application and Extractive Industry Licence (EIL) application to facilitate the extraction of the sand resource. This supporting documentation has been prepared to outline:

The planning context and the environmental attributes and values associated with the site. The proposed sand extraction process. Management of potential impacts associated with the proposed sand extraction. Decommissioning and rehabilitation following extraction of the sand resource.

This supporting documentation has considered the Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999 and Info Note PS06 – Guidelines for Extractive Industries, which was prepared in support of the local law. Table 1 outlines the specific criteria and where these have been addressed within the application package.

The sand resource is proposed to be extracted from approximately 18.8 hectares of the site (referred to as the ‘proposed sand extraction area’), and encompasses a sandy rise that is situated within the site. Section 4 and Section 6 of this document provides detail on the environmental attributes and values identified within the site, and how the proposed sand extraction within the site will be managed.

The environmental attributes and values located within the proposed sand extraction area have been summarised below:

The topography ranges from approximately 16 mAHD in the western portion, to 24 mAHD through the central portion and 19mAHD in the eastern portion.

The proposed sand extraction area is identified as ‘Sand’ and the geological unit S8 unit (Gozzard 1986).

The proposed sand extraction area has been classified as having ‘moderate to low risk of ASS occurring within 3 m of natural soil surface (or deeper)’. If ASS are present, this would occur beneath the lowest seasonal groundwater levels, and risks only posed when activities are proposed to extend below the groundwater levels (either excavation or dewatering).

Based on site specific groundwater monitoring the average annual maximum groundwater levels (AAMGL) beneath the site range from approximately 15 mAHD within the north-western portion of the site and 17 mAHD in the south-western portion of the site, and 16.5 mAHD in the eastern portion of the site.


OCM042.1/04/15

Project number EP14-057(01) | December 2014 Page iii




The proposed sand extraction area has been historically cleared and utilised for agriculture, primarily pasture and grazing. The north-eastern portion of the site contains areas of non-native trees that were planted historically as part of the agricultural land use within the site, while the north-western portion of the site contains some remnant native species. Overall vegetation has been identified as being ‘Parkland Cleared’, and composed of scattered paddock trees over pasture weed species.

The proposed sand extraction area supports limited fauna habitat values due to the historic clearing of native vegetation and livestock grazing. The majority of the site lacks native vegetation and the proposed sand extraction is very unlikely to impact on fauna species of conservation significance.

No areas of wetland are identified within the proposed sand extraction area. However, the proposed sand extraction area is located adjacent to a Resource Enhancement Wetland to the east and a Multiple Use Wetland to the west. The wetland values identified within the Resource Enhancement Wetland are considered to reflect a Multiple Use Wetland. The proposed sand extraction area is therefore not located adjacent to natural lakes, swamps or wetlands with conservation values.

Surrounding land uses are rural-based and include poultry farms, with poultry facilities located to the north, south and east of the site, horse agistment and grazing of livestock.

The proposed extraction of sand meets the broader land use considerations of the Western Australian Planning Commission (WAPC) and the Shire of Serpentine-Jarrahdale, by maximising the use of the sand resource, while ensuring that the sand extraction operation will not impact adversely on the environment or amenity of surrounding landholdings. Overall, the proposed sand extraction can be managed to avoid significant impacts on environmental attributes or values, or nearby land uses as:

The site is currently cleared of intact remnant vegetation and is largely composed of grazed paddocks. A number of remnant native trees species will be cleared, however these trees do not form areas of intact remnant vegetation nor are they utilised in any significant capacity by conservation significant fauna.

The current hydrological functions of the site will be maintained, primarily through limiting the vertical extent of sand extraction.

It is located within an area designated for poultry farms, with horse agistment, grazing and poultry farming the predominant land uses within the broader area. The proposed sand extraction is not expected to impact nearby sensitive land uses.

A summary of the proposed management framework has been provided below in Table A.

Table A: Summary of environmental factors and management actions

FACTOR MANAGEMENT ACTIONS

Vegetation Apply for a clearing permit pursuant to Part V of the Environmental Protection Act 1986 (EP Act) to clear a number of remnant native species within the north-western portion of the proposed sand extraction area. These trees are identified as ‘Parkland Cleared’, composed of scattered paddock trees over pasture weeds.

The extent of the proposed sand extraction area will be clearly marked using survey pegs and flagging tape to ensure clearing occurs within the identified area. Where required, temporary fencing will be utilised.

Trees located within 20m of the proposed sand extraction area that are to be retained will be clearly marked with flagging tape.

Vegetation that is cleared will be mulched within the site and stockpiled for use as part of rehabilitation and/or dust management requirements.

Topsoil will be stripped and stockpiled for use in rehabilitation of the proposed sand extraction area.


OCM042.1/04/15

Project number EP14-057(01) | December 2014 Page iv





Surface water and groundwater

Apply for groundwater licence to access groundwater for dust suppression purposes. Undertake annual ongoing monitoring of groundwater levels within the site, utilising the monitoring bores

shown in Figure 3. Provide at least one metre separation between the determined AAMGL and the post extraction ground

surface as part of the sand excavation process. Commence rehabilitation works at the completion of each stage wherever possible. Maintain all plant equipment in good condition to minimise potential for contamination (from accidental

discharges of hydrocarbons). Avoid excavation, vehicle movements or material stockpiling within 50 metres of the drain. Maintain all haul road surfaces in good condition with suitable grades to minimise potential for erosion from

rainfall.

Wetlands Provide at least one metre separation between the determined AAMGL and the post extraction ground surface as part of the sand excavation process.

Separation distances

No onsite processing of sand, including no crushing and no screening, is proposed as part of the sand extraction activities.

On-site management for noise and dust will minimise potential offsite impacts, including watering of the site during dry conditions and maintaining equipment in good working order. The management of noise and dust has been summarised in Table 13.

Monitor and follow-up complaints through a complaint register system. Rehabilitation of the site following the completion of sand excavation.

Visual impacts Provide additional planting along the site boundary directly adjacent to Hopeland Road, as shown in Figure

9. Maintain a 20 metre separation between the proposed sand extraction area and the site boundary, in

accordance with Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999. Minimise the amount of open ground at any one time through staged excavation and rehabilitation. Where possible, position topsoil stockpiles to form screening barriers to the extraction activities.

Dieback and weed management

Clearly mark the extent of proposed sand extraction area using survey pegs and flagging tape to ensure works do not extend outside the approved sand extraction area.

Maintain a 20 metre separation between the proposed sand extraction area and the site boundary, in accordance with Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999.

Ensure machinery and equipment arrives on site soil free, or provide wash-down areas for vehicles that require cleaning.

Limit duplication of existing access ways. For screening vegetation and rehabilitation, purchase plant species from nurseries with a Nursery Industry

Accreditation. Monitor for introduction of additional weed species, particular those identified as a Declared Plant (in

accordance with Biosecurity and Agriculture Management Act 2007). If identified, these will be controlled and/or removed from the site.

Decommissioning All vehicles and equipment required for the sand extraction activities will be removed from site. Retain existing facilities and infrastructure within the site, unless determined to be unsuitable for the future

land use. Batter areas to be graded in accordance with Shire of Serpentine–Jarrahdale Extractive Industries Local

Law 1999. These batter areas will be stabilised with ground cover (i.e. mulch or similar) and where appropriate vegetation.

Rehabilitation Establish topographic contours to be compatible with existing contours within portions of the site not excavated.

Stabilise batter areas to minimise the potential for erosion as a maximum of 1 to 3 side slopes. Re-spread topsoil stockpiled as part of the clearing works. The topsoil will be spread to a depth of 100 mm

and deep ripped to a depth of 300mm to assist in establishment of pasture species. Where required, seed for pasture will be spread to maximise growth and ensure 90 per cent pasture cover is

achieved

1 Introduction

1.1 Background

Goodfeel Enterprises Pty Ltd (Goodfeel) is proposing to extract sand from Lot 371 (No. 514) Hopeland Road, Hopeland (herein referred to as ‘the site’). The site is located within the Shire of Serpentine-Jarrahdale and is found 46 kilometres south of the Perth Central Business District, and approximately 11 kilometres south-west of the Mundijong town centre. The location of the site is shown in Figure 1.

Goodfeel is seeking development approval (DA) and an extractive industry licence (EIL) to extract sand located within a portion of the site. The proposed sand extraction is intended to supply an essential basic raw material that will be used for a variety of purposes such as clean fill sand and construction sand, to support infrastructure and urban development throughout the broader region.

1.2 Applicant and owner details

Goodfeel Enterprises Pty Ltd is the proponent for the DA and EIL application for the site. Goodfeel Enterprises Pty Ltd own the site, and the legal description of the land is an ‘Estate in Fee Simple’, being:

Lot 371 on Deposited Plan 202654, contained within Certificate of Title Volume 1339 Folio 584

A copy of the Certificate of Title has been included as Appendix A.

1.3 Proposed operations

Sand is proposed to be extracted from approximately 18.8 hectares of the site, and encompasses the sandy rise located within the site. It is proposed to occur on a staged basis and will include rehabilitation of the site to support grazing (or other uses), in accordance with the zoning of the site. Depending upon demand, it is estimated that the sand resource will support mining for five to 10 years.

1.4 Significance of the basic raw material

With the continued growth in Perth’s south-west and south-east corridors, there is an increasing demand for sand resources for construction purposes. Existing resources within the southwest and south-eastern metropolitan regions that have been historically established are largely exhausted, and new sources of sand are required for supply within the Perth Metropolitan Region.

The site contains substantial deposits of sand with properties that make it suitable for a wide range of uses although will be predominantly utilised as clean sand fill for land development and infrastructure provision.

2 Legislative Framework

As part of considering the proposed sand extraction within the site an overview of the relevant legislative framework applicable to the proposed land use has been undertaken and a summary has been provided below. This includes consideration of the key legislation and its associated requirements.

2.1 Planning and Development Act 2005

The Planning and Development Act 2005 (PD Act) provides for a system of land use planning and development in the State and for related purposes. The PD Act:

Establishes the Western Australian Planning Commission (WAPC). Gives power to the WAPC to make State planning policies, region planning schemes regional

interim development orders, planning control areas and improvement plans. Establishes the requirement to obtain approval from the WAPC before subdividing land. Gives power to local governments to make local planning schemes for their local government

area. Sets out a regime for the payment of compensation for injurious affection caused by the making of

a local or region planning scheme.

Under the PD Act, the Shire of Serpentine-Jarrahdale has the power to approve land uses in accordance with the relevant local planning scheme and in this regard Development Approval (DA) is required. This is discussed further in Section 3 below, and this document is intended to support the DA application process.

2.2 Environmental Protection Act 1986

The Environmental Protection Act 1986 (EP Act) aims to protect and enhance the environment through the prevention and control of pollution and environmental harm.

2.2.1 Part IV of the EP Act

Part IV of the EP Act is associated with the environmental impact assessment of proposals. The EPA is responsible for assessing the impacts of projects, proposals, town planning schemes and local scheme amendments on the environment and providing advice to the Minister for the Environment. This advice is guided by the policy and guidance prepared by the EPA

A proposal that has the potential to have a significant impact on the environment needs to be referred to the EPA. This is an obligation of the relative decision making authority, which in this case is the Shire of Serpentine-Jarrahdale. Given the limited environmental attributes and values identified within the site (outlined in further detail within Section 4), and that the sand extraction process can be appropriately managed so that it will not significantly impact on the environment or amenity of surrounding land uses, there is no identifiable need for referral pursuant to Part IV of the EP Act.

2.2.2 Part V of the EP Act

Part V of the EP Act provides a basis for environmental regulation and compliance, and encourages the promotion of best practice and waste minimisation and aims to ensure that the operations of


OCM042.1/04/15





industrial facilities protect the environment and includes the provision of works approvals and licences and clearing permits. The Department of Environment Regulation (DER) administers Part V of the EP Act.

2.2.2.1 Division 1 Pollution and environmental harm offences

Under Part V Division 1 of the EP Act, the DER grants works approval (for construction), and a licence or registration (for operation) for facilities that are prescribed in Schedule 1 of the Environmental Protection Regulations 1987 (EP Regulations). Prescribed premises are described as industries that have the potential to cause emissions and discharges to air, land or water (i.e. pollution of the environment). They encompass a range of activities and thresholds, and currently there are 89 categories of activities identified as ‘prescribed premises’.

The relevant prescribed premises category for the extraction of sand is Category 70 Screening etc. of materials on which material extracted from the ground is screened, washed, crushed, ground, milled, sized or separated. The production or design capacity, for which a licence is required, is 5 000 tonnes but less than 50 000 tonnes per year. If screening was to be required this will be to remove organic matter present within the soil profile. This is not expected given the depth of the sand resource and the historic clearing of remnant native vegetation within the site. If required, this would be well below the production or design capacity that would require a works approval or licence for Category 70. Therefore, no works approval or licence is required pursuant to Part V Division 1 of the EP Act.

2.2.2.2 Division 2 Clearing of native vegetation

Under Part V Division 2 of the EP Act, the clearing of native vegetation is an offence unless a clearing permit has been obtained or an exemption applies. As part of the detailed site survey (see Section 4) a small portion of the site (approximately 2.7 hectares) was identified as containing scattered paddock trees that are composed of remnant native species.

A clearing permit application will be lodged with the DER in accordance with Section 51C of the EP Act immediately following submission of the DA application and EIL application with the Shire of Serpentine-Jarrahdale. Sand extraction within the site can commence without the requirement to clear remnant native vegetation, and no clearing of the remnant native species will occur within the site until a clearing permit has been issued.

2.3 Rights in Water and Irrigation Act 1914

The Rights in Water and Irrigation Act 1914 (RIWI Act) provides for the protection and management of surface water and groundwater resources in Western Australia. The Department of Water (DoW) is responsible for managing and allocating terrestrial water resources. The DoW grants the right to take water from these resources by issuing licences with water entitlements, to individuals or companies who meet the DoW criteria.

Goodfeel propose to source groundwater for dust suppression purposes (as part of managing sand extraction activities within the site). A review of the DoW’s Water Register (a database provided by the Department of Water outlining groundwater availability and existing licences) indicated that groundwater allocation is available within the groundwater subarea that the site is located within. In accordance with the RIWI Act and the requirements of the DoW, a groundwater licence application will be lodged with the DoW immediately following submission of the DA application and EIL application with the Shire of Serpentine-Jarrahdale.


OCM042.1/04/15





2.4 Local Government Act 1995

In accordance with the Local Government Act 1995, the Shire of Serpentine-Jarrahdale has powers to prepare local laws that prescribe all matters that are required or necessary to perform any or all of its functions to meet the needs of current and future generations through environmental protection, social advancement and economic prosperity.

The Shire of Serpentine-Jarrahdale has prepared the Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999, which outlines the requirements to enable the Shire of Serpentine Jarrahdale to make decisions regarding Extractive Industry Licences. This document is intended to demonstrate how Goodfeel will fulfill the requirements outlined within this local law in order to facilitate the issue of an Extractive Industry Licence


OCM042.1/04/15





3 Planning Context

3.1 Zoning and proposed land use

The site is currently zoned ‘Rural’ under the Metropolitan Region Scheme (MRS) and ‘Rural’ under the Shire of Serpentine-Jarrahdale Town Planning Scheme (TPS) No. 2. It is also located within the ‘Poultry Farm Special Control Area’ under Shire of Serpentine-Jarrahdale TPS No. 2.

The ‘Rural’ zone is described as being ‘to accommodate the full range of rural pursuits and associated activities conducted in the scheme area’. Under the Shire of Serpentine-Jarrahdale TPS No. 2 as outlined within Table 1 (i.e. the Zoning Table) indicates that sand extraction is considered to be ‘Industry-Extractive’.

The land use ‘Industry-Extractive’ is described as:

The extraction of sand, gravel, limestone, clay, turf, soil, rock, stone, minerals, or similar substance from the land, and also includes the management of products from those materials when the manufacture is carried out on land from which any of the material so used is extracted or on land adjacent thereto, and the storage of such materials and products; and the production of salt by evaporation of sea water.

Within the Shire of Serpentine-Jarrahdale TPS No. 2, ‘Industry-Extractive’ is classified a discretionary use in ‘Rural’ zoned areas and the Shire of Serpentine-Jarrahdale Council may, at its discretion, permit this use.

In accordance with the Extractive Industries Local Law 1999, Goodfeel submits this report in support of an application for DA and an EIL. The license period is determined by the Shire of Serpentine-Jarrahdale Council and may be held for a maximum of 21 years.

3.2 Policy, strategy and guidance documents

In considering the proposed land use, Table 2 below outlines the relevant policies, strategies and guidelines, and how these have been accommodated within the applications and the associated sand extraction process.

Table 2: Summary of relevant policies, strategies and guidelines

POLICY/STRATEGY DESCRIPTION APPLICATION TO SITE

POLICY

State

State Planning Policy No. 1 (SPP 1)

SPP 1 (WAPC, 2006) identifies the five key principles that should underpin good decision making in land use planning and development. The five principles have been outlined below: Environment: to protect and enhance the key natural and cultural assets of the Western

Australia and deliver to all people a high quality of life which is based on environmentally sustainable principles.

Community: to respond to social changes and facilitate the creation of vibrant, safe and self-reliant communities.

Economy: to actively assist in the creation of regional wealth, support the development of new industries and encourage economic activity in accordance with sustainable development principles.

Infrastructure: to facilitate strategic development by making provision for efficient and equitable transport and public utilities.

Regional Development: to assist the development of regional Western Australia by taking account of the special assets and accommodating the individual requirements of each region.

The proposed sand extraction is intended to support land development that is currently occurring within the south-west and south-east corridors of the Perth Metropolitan Region. The extraction activities within the site have been proposed to occur to minimise the extent of travel required to transport this material to the required locations for its ultimate usage. It will support a local workforce and designed to minimise impacts on the surrounding community.

State Planning Policy 2.1 – The Peel Harvey Coastal Plain Catchment (SPP 2.1)

SPP 2.1 was developed to ensure that land use changes within the Peel-Harvey Estuary System that are likely to cause environmental damage are brought under planning control and are prevented (Department of Planning 2003). Generally the policy states that any development, including the construction of buildings should aim to: Reduce the nutrient load discharging into the Peel-Harvey Estuary catchment. Encourage the retention and rehabilitation of existing remnant vegetation. Minimise the impact to the environment of changes in land use. Prevent land uses that result in excessive nutrient export into the drainage system. SPP 2.1 is related to the consideration and application of the Environmental Protection Peel Inlet – Harvey Estuary Policy 1992.

With regard of the proposed sand extraction activities, the Peel-Harvey Estuary Catchment is not likely to be significantly affected. The site is currently cleared of intact remnant vegetation and largely composed of grazed paddocks. The sand extraction within the site is not expected to alter nutrient levels within surface water or groundwater, or result in the export of additional nutrients to the Peel-Harvey Estuary catchment.

State Planning Policy 2.4 – Basic Raw Materials (SPP 2.4)

The objectives of SPP 2.4 is to: Identify the location and extent of known basic raw material resources. Protect Priority Resource Locations, Key Extraction Areas and Extraction Areas from

being developed for incompatible land uses which could limit future exploitation.

The site is not specifically identified as a Basic Raw Materials resource within SPP 2.4 however sand suitable for a variety of purposes such as clean fill sand and construction sand, to support infrastructure and urban development throughout the broader region, has been identified.


OCM042.1/04/15







Ensure that the use and development of land for the extraction of basic raw materials does not adversely affect the environment or amenity in the locality of the operation during or after extraction.

Provide a consistent planning approval process for extractive industry proposals including the early consideration of sequential land uses identifies areas.

Under the policy, there is a presumption against the introduction of sensitive land uses (such as residential) within the vicinity of Basic Raw Materials which could be adversely affected by existing or potential extractive industries. SPP 2.4 suggests that before the introduction of sensitive land uses within 1,000 metres of designated Basic Raw Materials resources, the significance of the resource and the likely effects of extracting the resource need to be considered during the land use planning process.

The excavation of sand from within the site is unlikely to detrimentally impact on environmental attributes or values, or nearby land uses. The site is currently cleared of intact remnant vegetation and largely composed of grazed paddocks. It is located within an area designated for poultry farms, with horse agistment, grazing and poultry farming the predominant land uses within the broader area. This outlined further in Section 4 and Section 6. The proposed extraction of sand is consistent with the objectives of SPP 2.4, by maximising the use of the sand resource, while ensuring that the sand extraction operation will not impact adversely on the environment or amenity of surrounding landholdings.

State Planning Policy No. 3.4 Natural Hazards and Disasters (SPP 3.4) (WAPC 2006b)

SPP 3.4 was prepared to ensure that mitigation measures for potential natural hazards and disasters are integrated into the process of land use planning. Hazards considered under this policy include, floods, severe storms, erosion, and bushfires. The objectives of the policy are to: Include planning for natural disasters as a fundamental element in the preparation of all

statutory and non-statutory planning documents, specifically town planning schemes and amendments, and local planning strategies.

Through the use of these planning instruments, minimise the adverse impacts of natural disasters on communities, the economy and the environment.

The WAPC have recently released Draft State Planning Policy 3.7 Planning for Bushfire Risk Management (WAPC 2014a). The aim of this policy is to assist in reducing the risk of bushfire to people, property and infrastructure by taking a risk minimisation approach to development proposed in bushfire-prone areas.

There are limited risks from natural disasters and hazards associated with sand extraction within the site. Sand extraction activities will be managed to minimise: Erosion, through the appropriate grading and stabilisation of batters within

the sand extraction area. Bushfire by providing an evacuation plan to be communicated to workers if

a bushfire starts in nearby areas. Flooding, with the hydrological functions of the site to be maintained, with

the risk of groundwater levels or surface water run-off increasing considered to be low.

Severe storms, with appropriate shelter provided within the site and work within the site to stop if storm conditions become unsafe for ongoing operations.

State Planning Policy 4.1 – State Industrial Buffer Policy (SPP 4.1)

The purpose of SPP 4.1 is to: Provide a consistent approach for the definition and securing of buffer areas around

industry, infrastructure and some special uses. Protect industry, infrastructure and special uses from the encroachment of incompatible

land uses. Provide for the safety and amenity of land uses surrounding industry, infrastructure and

special uses. Recognise the interests of existing landowners within buffer areas who may be affected

by residual emissions and risks, as well as the interests, needs and economic benefits

This policy is addressed through the consideration of appropriate setbacks; with the nearest sensitive land uses located approximately 300 metres to the north and south of the site. The proposed sand extraction within the site does not require blasting or processing of sand, apart from separating organic matter from the sand, and the resultant transportation of the sand from site. The low intensity nature of the sand extraction works in addition to the onsite management of noise and dust means that offsite impacts on surrounding sensitive land uses is likely to be low.


OCM042.1/04/15







of existing industry and infrastructure which may be affected by encroaching incompatible land uses.

SPP 4.1 refers to EPA Guidance for the Assessment of Environmental Factors No. 3 Separation Distances between Industrial and Sensitive Land Uses (2005) to provide guidance on appropriate separation distances between industrial and sensitive land uses. Guidance for the Assessment of Environmental Factors No. 3 Separation Distances between Industrial and Sensitive Land Uses (EPA 2005) outlines that sand extraction activities have a recommended separation distance of between 300 and 500 metres depending upon the size of the operation and the processing methods utilised. These are generic separation distances which are intended to be applied through the land use planning and environmental impact assessment processes in the absence of any detailed technical work being undertaken. They are inherently conservative in order to accommodate the variation in both the scale and management practices adopted in sand extraction operations.

State Planning Policy 4.3 – Poultry Farms (SPP 4.3)

SPP 4.3 was gazetted in December 2003, with the objectives of the policy being: To ensure that new poultry farms are established in locations suitable to their

operational requirements; To minimise the impact of poultry farms on residential, rural-residential and other

potentially incompatible uses; To protect the interests of existing poultry farms in the face of encroaching

development.

The site is located in an area recognised by the Shire of Serpentine-Jarrahdale as being important for the establishment and continued growth of poultry farms, with the broader area identified in the ‘Poultry Policy Overlay’ under the Shire of Serpentine-Jarrahdale TPS No. 2. A number of poultry farms are located within the vicinity of the site. The proposed sand extraction operation is unlikely to detrimentally affect the operation of the poultry farms, with the nearest facility approximately 400 metres to the south-west of the proposed sand extraction area. Dust and noise will be managed as part of operations within the site, and traffic is unlikely to increase significantly as a result of the proposed sand extraction. Alternatively, the proposed sand extraction activities will not be affected by the existing poultry farms operations, and in particular by odour.

Environmental Protection Peel Inlet – Harvey Estuary Policy 1992

This policy sets out environmental quality objectives for the Peel Inlet – Harvey Estuary which aim to rehabilitate the estuary and protect it from further degradation. The objectives focus on limiting the total phosphorus flowing into the estuary from its major tributaries, being the Serpentine River, Murray River and Harvey River. These objectives are to be achieved and maintained through: The implementation of the planning policy by local authorities through Town Planning

Schemes, and by the WAPC through the MRS. Appropriate land management by landholders and management authorities.

While the site is located within the Peel-Harvey Coastal Plain Catchment, the proposed sand extraction activities are not expected to alter nutrient levels within the surface water or groundwater, or result in the export of additional nutrients to the Peel-Harvey Estuary catchment. The site is currently cleared of intact remnant vegetation and largely composed of grazed paddocks.

Local Planning Policy No. 1 Bond and Bank guarantees (LPP 1) (Shire of Serpentine-Jarrahdale 20001)

LPP1 outlines when the Shire of Serpentine- Jarrahdale may require bonds or bank guarantees to secure compliance with various approvals, including extractive industry licences.

The requirement for a bond or bank guarantee will be determined by the Shire of Serpentine-Jarrahdale as part of the DA and EIL application process.

Local Planning Policy No. 4 Revegetation (LPP 4) (Shire of Serpentine-Jarrahdale 2010)

LPP 4 has been prepared to compliment a range of State government policies, and has primarily been developed to facilitate the revegetation of cleared land using native flora of local provenance. The policy also aims to consider the requirements of the Peel-Harvey Coastal Catchment and bushfire management planning, in which firebreaks, planning of low fuel areas and use of low flammability native species are included as a part of revegetation.

Following the completion of the sand extraction activities, it is intended that the site will be returned to a condition capable of supporting agricultural-related activities, in line with its current land use. Where vegetation planting is undertaken within the site, planting will be in accordance with Keeping It Local (Shire of Serpentine-Jarrahdale).

Local Planning Policy No. 8 Landscape Protection (LPP 8) (Shire of Serpentine-Jarrahdale 2002)

This policy provides for the protection of the scenic values and amenity within the Shire of Serpentine-Jarrahdale, in particular the ‘leafy green’ viewscapes. This policy applies to specific areas within the Shire of Serpentine-Jarrahdale, and includes the site. Key objectives of this policy include to: Maintain the integrity of landscapes within the policy area. Protect and enhance landscape, scenic and townscape values through control over

scenic corridors including South Western Highway and natural watercourses.

Local Planning Policy No. 21 Management Plans (LPP 21) (Shire of Serpentine-Jarrahdale 2009a)

LPP 21 was developed by the Shire of Serpentine-Jarrahdale to ensure that a standard approach to the structure and content of management plans is taken and is considered particularly important when an area contains environmental, conservation or biodiversity values. A number of the aims of this policy have been summarised below: Enable better continuity in land management through the provision of comprehensive

plans which address but are not limited to a number of different areas. Provide a collated checklist of requirements. Deliver a balance of social, environmental and economic outcomes. Require proponents, as a condition of subdivision or development, to prepare a

management plan. LPP 21 provides a list of requirements which proponents and Shire of Serpentine-Jarrahdale staff must address when developing management plans.

The requirements of LPP 21 have been addressed through the management actions outlined within Section 5 and Section 6.

Local Planning Policy No. 26 Biodiversity Planning (LPP 26) (Shire of Serpentine-Jarrahdale 2009b)

LPP 26 aligns with the Shire of Serpentine-Jarrahdale’s Local Biodiversity Strategy (Ironbark Environmental 2009). This policy recognises that the Swan Coastal Plain has been significantly cleared as a part of historical land uses and details the Shire of Serpentine-Jarrahdale’s commitment to the conservation of biodiversity and the restoration of the environment. LPP 26 aims to: Contribute towards biodiversity conservation goals and targets outlined in the Local

Biodiversity Strategy. Protect natural areas and maintain the values and ecosystem services of these areas in

the long-term. Ensure natural areas are not negatively impacted by development. Ensure the protection, restoration or management of natural areas, or the revegetation

of other areas to increase fauna habitat.

No Local Natural Areas are identified within the site. In addition, no areas with conservation values will be impacted by the proposed sand extraction activities. The site is cleared of remnant vegetation values, and is largely composed of cleared paddocks. Following the completion of the sand extraction activities, it is intended that the site will be returned to land capable of supporting agricultural-related activities. Any planting of vegetation within the site will be undertaken in consideration of Keeping It Local (Shire of Serpentine-Jarrahdale).

Local Planning Policy No. 43 Hazards and Natural Disasters (LPP 43) (Shire of Serpentine-Jarrahdale 2011a)

LPP 43 outlines the Shire of Serpentine-Jarrahdale’s position with regard to land use planning and consideration of hazards and natural disasters, in which the planning and design of future developments should minimise the vulnerability of future developments and improve resilience to such events. As with State Planning Policy 3.4 Natural Hazards and Disasters (WAPC 2006b), the hazards and natural disasters considered in the policy include flooding, bushfires,

STRATEGY

Local

Shire of Serpentine-Jarrahdale Rural Strategy Review 2013

The Shire of Serpentine-Jarrahdale Rural Strategy was recently reviewed (2013) and outlines the Shire of Serpentine-Jarrahdale’s vision with regard to land use within the rural areas. The key themes identified through the review for the rural areas include: Protection of natural assets, including minimising nutrient export and protection of

remnant vegetation. Protection of rural character, and to retain the rural identity of the area. Facilitate productive rural areas, this includes maintaining and enhancing the use of

palusplain areas.

Under the Shire of Serpentine-Jarrahdale Rural Strategy Review 2013, the site is located within the ‘Rural Policy Area’ with the purpose of this area being to maintain the integrity of the Shire of Serpentine-Jarrahdale’s rural and agricultural character. Most of this area is located on the Bassendean Dune and Sandplain land systems which consist of sandy soils with low productivity and low lying areas prone to waterlogging. Within the previous rural strategy, protection of wetlands and remnant vegetation is noted as an issue throughout most of this area and that the subdivision of new lots below a minimum of 40 hectares is not supported. Additionally, the site is located within the ‘Hopeland Urban Village Investigation Area’ and the ‘Poultry Policy Overlay’ area. These areas aim to support future investigations into an urban village and productive areas for poultry farms respectively. In view of the above, it is considered that any investigation for this area would be part of the Shire’s long term planning. The proposed sand extraction within the site will be in accordance with the Rural Strategy 1994 and the recent review (2013), with the site to be rehabilitated to support rural land uses following completion of the sand extraction.

4 Existing environment

4.1 Local context

The site is located within the south western corridor of the Perth Metropolitan Area, within the Shire of Serpentine-Jarrahdale. The broader area supports predominantly agricultural-based land uses, and is largely cleared of remnant vegetation. The Shire of Serpentine-Jarrahdale Local Biodiversity Strategy (Ironbark Environmental 2009) indicates that natural areas within the Shire of Serpentine-Jarrahdale have been significantly impacted since European settlement, especially on the coastal plain and foothills, with approximately 11 per cent of remnant vegetation remaining on land west of South West Highway.

4.2 Climate

The site experiences a Mediterranean climate, with dry summers and cool wet winters. The majority of rainfall within the region occurs between May and October, and on average is between 600 to 1000 mm per year. In the last 40 years there has been a marked decrease in rainfall (between 10 to 15 % decrease), with a noticeable shift to a drier climate across the south-west of Western Australia (CSIRO 2009).

Climatic statistics for the site are referenced from the nearest Bureau of Meteorology (BOM) monitoring station, which is Serpentine, approximately 9 kilometres east of the site. The average annual rainfall for the site is 910 mm (based on data collected up to the year 2013) (BOM 2014).

4.3 Topography

The natural topography within the site exhibits both an eastern and western aspect, with the central portion of the site a natural high point. Within the site surface, elevation ranges from approximately 15 metres Australian Height Datum (mAHD) along the western boundary of the site to the 24mAHD through the central portion of the site (generally associated with a sandy rise/ridge) before gradually sloping down to approximately 18 mAHD along the eastern boundary of the site

The topography within the proposed sand extraction area ranges from approximately 16 mAHD in the western portion, to 24 mAHD through the central portion and 19mAHD in the eastern portion.

The topography of the site is shown in Figure 2 and Appendix C.

4.4 Soils and landforms

The site is located on the Swan Coastal Plain, which forms the central portion of the Perth Basin extending from the Darling Fault in the east to the continental slope west of Rottnest Island, and from the Murchison River in the north to the Southern Ocean in the south (Seddon 2004). The site is found within the Bassendean Dune portion of the Swan Coastal Plain.

Landform and soil mapping prepared by Churchward and McArthur (1980) indicates that site occurs within the Southern River complex. This complex is described as ‘sandplain with low dunes and many intervening swamps; iron and humus podzols, peats and clays’.


OCM042.1/04/15





The Perth Metropolitan Region 1: 50,000 Environmental Geology Series, Serpentine (Part Sheets 2033 I and 2133 IV) (Gozzard 1986) indicates that the majority of the site is comprised of ‘Sand’ (including S8 and S10), with the S8 unit identified through the central portion of the site. The general descriptions of these are provided below in Table 3.

Table 3: Environmental Geology Series map unit descriptions

MAP UNIT DESCRIPTION

S8 Sand – white to pale grey at surface, yellow at depth; fine to medium-grained, moderately sorted sub-angular to sub-rounded minor heavy minerals, of eolian origin.

S10 Sand – as S8 over sandy clay to clayey sand of the Guildford Formation, of eolian origin

4.5 Acid Sulfate Soils

Acid Sulfate Soils (ASS) is the name commonly given to naturally occurring soils and sediment containing iron sulphide (iron pyrite) materials. In their natural state ASS are generally present in waterlogged anoxic conditions and do not present any risk to the environment. ASS can present issues when oxidised, producing sulphuric acid, which can impart a range of impacts on the surrounding environment, infrastructure and human health.

Based on the Department of Environment Regulation (DER) Acid Sulfate Soils mapping, the site has been classified as having ‘moderate to low risk of ASS occurring within 3 m of natural soil surface (or deeper)’. Generally, if ASS are present within a site, these would occur beneath the lowest seasonal groundwater levels, and risks only posed when activities are proposed to extend below the groundwater levels (either excavation or dewatering).

4.6 Hydrology

4.6.1 Groundwater

The site is not located within the area covered by the DoW Perth Groundwater Atlas, and groundwater information has been obtained from a review of existing DoW monitoring bore information and site specific groundwater monitoring.

Plate 1 (below) shows the results from nearby groundwater monitoring data from the Water Information database between the year 2000 and 2014 (Department of Water 2014).


OCM042.1/04/15





Plate 1: Long-term groundwater levels based on nearest Department of Water WIN data

Emerge Associates have undertaken monitoring of groundwater levels within the site, to assist in determining a suitable depth of excavation. Groundwater monitoring for the site commenced in November 2014. The Average Annual Maximum Groundwater Level (AAMGL) across the site range between approximately 15 mAHD within the north-western portion of the site and 17 mAHD in the south-western portion of the site, and 16.5 mAHD in the eastern portion of the site. The depth to maximum groundwater is approximately 1 m below ground level (m BGL) within the western portion of the site 1.5 m BGL and 2.5 m BGL respectively. The greatest depth to groundwater occurred within the central portion of the site, while the least depth to groundwater occurred within the north-western portion of the site.

The AAMGL for the site has been calculated based on the monitoring data collected to date and comparison with groundwater data provided by the DoW (outlined above) and is provided in Table 4.

OCM042.1/04/15





4.6.2 Surface water

Within the site, the only surface water feature is a man-made sump located within the central-eastern portion of the site. The sump contains Typhus orientalis and is approximately 0.04 hectares in size. The location of the sump is shown within Figure 3.

Punrak Drain is located adjacent to the western boundary of the site and is shown in Figure 3. The drain forms part of the surface water drainage network which flows into the Serpentine River, the major river in the northern Peel-Harvey Catchment. The Peel-Harvey Catchment comprises the Serpentine, Harvey and Murray River systems which drain into the Peel Inlet and Harvey Estuary, a Ramsar listed wetland of international significance, located south of Mandurah, approximately 40 km south of the site. The Peel-Harvey Catchment is protected and managed under the WAPC SPP 2.1 The Peel-Harvey Coastal Plain Catchment and the EPA Environmental Protection Peel Inlet – Harvey Estuary Policy 1992.

4.6.3 Public Drinking Water Source Areas

Public Drinking Water Source Areas (PDWSAs) are proclaimed by the DoW to protect the quality of identified drinking water sources, which can be surface water or groundwater sources (DoW 2013). They are proclaimed under the Metropolitan Water Supply, Sewerage and Drainage Act 1909 or the Country Areas Water Supply Act 1947 as Water Reserves, Catchment Areas or Underground Water Pollution Areas (DoW 2009a). PDWSAs provide the majority of Western Australia’s drinking water supplies and can be vulnerable to contamination from a range of land uses and water based activities (DoW 2009a). Where a PDWSA is identified, consideration needs to be given to the intended land use and associated activities to ensure that they are appropriate in meeting the water protection quality objectives of the area.

The site is not located within any proclaimed or proposed PDWSA.

4.7 Flora and Vegetation

4.7.1 Regional context

The site is located within the Swan Coastal Plain Interim Biogeographical Regionalisation for Australian (IBRA) Region (Thackway and Cresswell 1995) which is broadly categorised as Banksia low woodland on leached soils with Melaleuca swamps on ill-drained soils and woodlands of Tuart (Eucalyptus gomphocephala), Jarrah (Eucalyptus marginata) and Marri (Corymbia calophylla) on less leached soils.

Vegetation complex mapping undertaken by Heddle et al. (1980) for parts of Western Australia uses combination of landform, soil and rainfall parameters, and indicates that the site is located within the “Southern River Complex”. This complex is described as “Open woodland of Corymbia calophylla - Eucalyptus marginata - Banksia spp. with fringing woodland of Eucalyptus rudis - Melaleuca rhaphiophylla along creek beds”.

Available information indicates that within the Swan Coastal Plain, approximately 19.7% of the pre 1750 clearing extent of remnant vegetation remains of the Southern River Complex, with 2.16% of this under formal protection and 2.18% under informal protection (WALGA 2013).


OCM042.1/04/15





4.7.2 Significant flora

Species of flora acquire ‘Threatened’ or ‘Priority Flora (PF)’ conservation status where populations are restricted geographically or threatened by local processes. The Department of Parks and Wildlife (DPaW) recognises these threats and subsequently applies regulations towards population protection and species conservation. The DPaW enforces the Wildlife Conservation Act 1952 (WC Act) to conserve Threatened species and protect significant populations. PF species are potentially rare or threatened and are classified in order of threat. Threatened and PF category definitions are listed in Appendix D.

Some Threatened species listed under the WC Act are also listed at a Federal level, pursuant to the Environment Protection and Biodiversity Conservation 1999 Act (EPBC Act).

A search of DPaW’s databases for Threatened and PF conducted for the site identified a total of 15 Threatened and three PF as occurring within the broader local area (within 5 km of the site). The threatened and PF species have been detailed in Table 5 below.

4.7.3 Threatened ecological communities

In Western Australia, Threatened Ecological Communities (TECs) are assessed by the Western Australian Threatened Ecological Communities Scientific Advisory Committee and endorsed by the Minister for the Environment. Categories of TECs are outlined in Appendix D. TECs are recognised as specific ecological communities that are rare or under threat. Generally, TECs can be described as vegetation communities that are assemblages of species that occur together in a particular type of habitat.

TECs are not afforded direct statutory protection at a state level but their significance is acknowledged through other state environmental approval processes such as Environmental Impact Assessment pursuant to Part IV and Part V of the Environmental Protection Act 1986 (EP Act). Some TECs are also afforded statutory protection at a Federal level pursuant to the EPBC Act.

Ecological communities with insufficient information available to be considered a TEC, or which are rare but not currently threatened, are placed on the Priority list and referred to as Priority Ecological Communities (PECs). Categories of PECs are outlined in Appendix D.

A search was conducted of DPaW’s TEC and PEC database as well as the EPBC Act list of Matters of National Environmental Significance. Six TECs were found to occur within 5 km of the site and have been detailed in Table 6 below. No PECs were found to occur within 5 km of the site.

4.7.4 Site specific flora and vegetation survey

A Level 1 flora and vegetation assessment (in accordance with EPA Guidance Statement Number 51 - Terrestrial flora and vegetation surveys for environmental impact assessment in Western Australia (EPA 2004)) was undertaken across the site and included an assessment of the wetland values present.

The flora and vegetation survey indicated the presence of native flora species across the site, however the majority of these were found in areas consisting of ‘Parkland Cleared’ native trees over a pasture weed dominated understorey and were thus not considered to constitute ‘intact’ plant communities. The site also contained areas of planted tree species, which are not considered to be endemic species found within the broader area or region. The areas of vegetation within the site are shown on Figure 4, and outlined in further detail in Appendix D.

The native species listed in Table 7 were recorded within the site. No Threatened or Priority Flora species or TECs or PECs were found to occur within the site, nor are any considered likely to occur due to the high level of historical disturbance and widespread weed invasion which has resulted in the removal of almost all native understorey species.

The majority of the site was considered to be in ‘Completely Degraded’ condition due to historical clearing and extensive grazing that has resulted in the removal of most native flora species. The ‘Completely Degraded’ areas of the site include some areas containing scattered or isolated native trees such as Corymbia calophylla, Melaleuca preissiana and Eucalyptus marginata. An example of these areas is shown in Plate 2. Some small scattered patches were considered to be in ‘Degraded’ condition, as they contained several native species comprising both the overstorey and understorey layers and in which native flora species were not isolated occurrences, and are shown in Plate 3. No vegetation was considered to be in ‘Good’ or better condition.

The mapped vegetation condition across the site is shown in Figure 5.

4.8 Bush Forever

The Government of Western Australia’s Bush Forever Policy is a strategic plan for conserving regionally significant bushland within the Swan Coastal Plain portion of the Perth Metropolitan Region. The objective of Bush Forever is to protect comprehensive representations of all original ecological communities by targeting a minimum of 10% of each vegetation complex for protection. Bush Forever sites are representative of regional ecosystems and habitat and have a key role in the conservation of Perth’s biodiversity (Government of Western Australia 2000).

No Bush Forever Sites have been identified within the site.

4.9 Ecological Linkages

Biodiversity or ecological linkages can be described as any area of remaining native vegetation that provides a corridor or linkage between larger patches of vegetation to allow movement of flora and fauna and their genetic material through the landscape, helping to maintain metapopulations. Linkages can prevent isolation of flora and fauna and help prevent the extinction of species. Ecological linkages can either be continuous or near continuous. The more fractured the linkage is, the less efficient the flora and fauna movement along the corridor.

Within the Shire of Serpentine-Jarrahdale ecological linkages have been proposed to encompass natural linkage features, such as major waterways or vegetated corridors. These ecological linkages are based on regional linkages, which were previously designated by the State Government in Bush Forever (Government of Western Australia 2000), Perth’s Greenways (Tingay and Associates 1998) and the System 6 study (Department of Conservation and Environment 1983). The implementation of the corridors is supported by the Western Australian Local Government Association and Perth Biodiversity Project (WALGA and PBP 2004) as a means of providing best practice guidance for local government biodiversity planning.

No ecological linkages have been identified within the site.

4.10 Environmental Sensitive Areas

Environmentally Sensitive Areas (ESAs) are areas prescribed under the Environmental Protection (Clearing of Native Vegetation) Regulations 2004 and have been identified in order to protect the native vegetation values of areas surrounding significant, threatened or scheduled ecosystems or communities. Within an ESA none of the exemptions under the Environmental Protection (Clearing of Native Vegetation)) Regulations 2004 apply. However, exemptions under Schedule 6 of the Environmental Protection Act 1986 still apply.

No ESAs are identified within the site.

4.11 Local Natural Areas

The Shire of Serpentine-Jarrahdale has prepared a Local Biodiversity Strategy (Ironbark Environmental 2008) which provides a number of goals for the retention, protection and management of natural areas throughout the Shire.

Within the strategy, Local Natural Areas (LNAs) are described as any physical area that contains native species or ecological communities in a relatively natural state, that are important locally,


OCM042.1/04/15





meeting one or more criteria as outlined in the Local Biodiversity Strategy (Ironbark Environmental 2008). They are natural areas that exist outside of DPaW managed estates, regional parks and Bush Forever sites.

No Local Natural Areas were identified within the site.

4.12 Terrestrial Fauna

The conservation status of fauna species in Western Australia is assessed under the state administered WC Act. DPaW also produces a list of priority species which while not considered threatened under the WC Act, there is concern over their long-term survival. As well as those species protected under the WC Act, the Federal government also maintains a list of protected species under the EPBC Act.

To understand the extent of significant fauna species that are likely to occur within the local area searches were undertaken of the DPaW’s NatureMap Database and the EPBC Act Protected Matters database. It is important to note that these searches do not take into account the types and condition of fauna habitat occurring on the site, but are based on the proximity of the site to known occurrences of significant species. The significant species identified as potentially occurring within the site are listed below in Table 8.

No fauna surveys have been undertaken within the site, however as part of the Level 1 flora and vegetation survey, the potential for conservation significant fauna to occur within the site was considered. Of the species listed in Table 8, the three black cockatoo species have the potential to occur within the site.

A review of DPaW databases indicates that potential Carnaby’s black cockatoo foraging habitat was mapped as occurring within the south-eastern portion of the site. This area is composed primarily of planted trees, however five native trees are located within this portion of the site that could be considered as foraging habitat. There was some historic foraging evidence from the forest red-tailed black cockatoo observed within the south-eastern portion of the site; however the majority of foraging evidence within the site was predominantly from the common red-capped parrot, and was largely associated with the areas of Corymbia calophylla in the south-western and south-eastern portions of the site.

Outside of the mapped potential foraging habitat, the site contained a number of tree species that are commonly foraged by species of black cockatoo (and include: 26 Eucalyptus marginata; three Eucalyptus gomphocephala and 15 Corymbia calophylla). These trees were contained within areas of ‘Parkland Cleared’ and ‘Completely Degraded’ vegetation, with the remnant trees all that remained of the original plant assemblages. A number of these trees had a Diameter at Breast Height (DBH) greater than 500 mm, and could potentially be used for breeding by species of black cockatoo; however again these were located within areas of ‘Completely Degraded’ vegetation and were not associated with intact foraging habitat likely to support a population of black cockatoos. The vegetation within the site is unlikely to form significant habitat for the three black cockatoo species, particularly when better quality foraging habitat is located directly north and south of the site, as well as approximately 5 kilometres further north and associated with Bush Forever Site 368.

A summary of the habitat values identified within the site have been provided in Appendix D.

Overall the site supports very limited fauna habitat values due to the historic clearing of native vegetation and livestock grazing. The majority of the site lacks native vegetation and the proposed sand extraction is unlikely to impact on fauna species of conservation significance.

4.13 Wetlands

DPaW maintains the Geomorphic Wetlands of the Swan Coastal Plain database which identifies wetland areas and categorises individual wetlands into specific management categories, namely Conservation, Resource Enhancement and Multiple Use (Hill et al 1996). The management categories have been provided in Table 9 below. The geomorphic wetland database is continually updated with site specific wetland surveys providing new and relevant information.

Table 9: Wetland management categories and management objectives (WAPC 2005)

MANAGEMENT

CATEGORY

DESCRIPTION OF WETLAND MANAGEMENT OBJECTIVES

Conservation (CCW) Supports high levels of attributes and functions

Preserve wetland attributes and functions through reservation in national parks, crown reserves and state owned land. Protection provided under environmental protection policies.

Resource Enhancement (REW)

Partially modified but still supporting substantial functions and attributes

Restore wetland through maintenance and enhancement of wetland functions and attributes. Protection via crown reserves, state or local government owned land, environmental protection policies and sustainable management on private properties.

Multiple Use (MUW) Few wetland attributes but still provide important hydrological functions

Use, development and management considered in the context of water, town and environmental planning through land care.

Two wetlands occur within the site and are classified as a Resource Enhancement Wetland (REW) and Multiple Use Wetland (MUW) and are shown in Figure 6 and outlined in Table 10 below. REW UFI No. 15364 is an extensive wetland occupying 2635 hectares extending out to the east of the site. A review of aerial photography indicates that much of the area outside of the site mapped as REW retains limited native vegetation.

Table 10: Wetland areas present within the site

UNIQUE FEATURE IDENTIFIER (UFI) WETLAND TYPE MANAGEMENT CATEGORY

15364 Dampland Resource Enhancement

15785 Palusplain Multiple Use

The wetlands within the site form part of the Bennett Brook consanguineous suite, of which 7.7% is classified as Conservation Category Wetlands (CCWs) (DPaW 2013).

From a remnant vegetation point of view, the majority of the two wetlands within the site are in ‘Completely Degraded’ condition. A small portion of UFI 15785 contains vegetation in ‘Degraded’ condition and is associated with two small areas that contain scattered Melaleuca preissiana over scattered Juncus pallidus, or Corymbia calophylla and Melaleuca preissiana over pasture weeds.

Based on the evaluation of the wetland values using DPaW’s evaluation methodology (DPaW 2013), the portion of REW UFI No. 15364 within the site does not reflect any of the high level values. The most appropriate management category for the portion of REW UFI No. 15364 within the site was considered to be MUW based on the results of the evaluation.

The outcomes of the preliminary wetland assessment are provided in Appendix D.


OCM042.1/04/15





4.14 Current land uses

The site was historically largely cleared of remnant vegetation and utilised for grazing, with a dwelling and auxiliary features located adjacent to the central-southern boundary of the site.

4.15 Surrounding land uses

The areas to the north, east and south are zoned ‘Rural’ under the MRS and Shire of Serpentine-Jarrahdale TPS No. 2. In general, these areas are utilised for:

Poultry farms, with facilities located to the north, south and east of the site Horse agistment Grazing of livestock.

Directly adjacent to the western boundary of the site is and area reserved for ‘Drainage Purposes’ and is associated with Punrak Drain. As outlined previously, Punrak Drain forms part of the agricultural drainage system that aims to control groundwater throughout the region and discharges to the Serpentine River, located to the south of the site, and is shown in Plate 4.

4.16 Heritage

4.16.1 Aboriginal heritage

An online search for relevant aboriginal heritage information was undertaken using the Department of Aboriginal Affairs (DAA) Aboriginal Heritage Inquiry System (DAA 2014). This system incorporates both the heritage site register and the heritage survey database. The Aboriginal Heritage Site Register is maintained pursuant to Section 38 of the Aboriginal Heritage Act 1972 (AHA) and contains information on over 22,000 listed Aboriginal sites throughout Western Australia.

No Aboriginal heritage sites were identified within the site.

Although no Aboriginal heritage sites were identified within the site, it is important to note that if during construction Aboriginal artefacts or sites are uncovered, these are protected under the AHA and works should cease and a suitably qualified expert should be brought in to survey the potential site. If required based on the outcome of the survey, permission under the AHA to manage and disturb sites should be sought.

4.16.2 Non-indigenous heritage

In order to determine actual or potential presence of sites or features of non-indigenous heritage significance within the site a review of readily available information at a federal, state and local government level was undertaken to determine if there were any of the following within the site:

World Heritage Sites National Heritage Sites Commonwealth Heritage Sites Sites listed on the Register of the National Estate Sites listed in the Shire of Serpentine-Jarrahdale Municipal Heritage Inventory List.

Searches of online databases found that no listed heritage sites occur within the site.

4.17 Visual Amenity

The Shire of Serpentine-Jarrahdale Landscape Protection Policy 8 Landscape Protection targets areas of high landscape value and aims to maintain the integrity of these landscape areas and features by introducing requirements and controls on developments. The site has not been identified in an area of high landscape value, however visual amenity considerations have been discussed further below.

Currently, the site is characterised by cleared paddocks, interspaced with trees of differing size and species. Adjacent to the eastern boundary of the site, along Hopeland Road, are a number of remnant native species which screen a portion of the site from Hopeland Road, shown in Plate 5. The site forms part of a natural high point within the surrounding landscape, with the surrounding areas generally located within flatter areas of the landscape.

The site is able to be viewed from one publicly accessible road, Hopeland Road, which is located adjacent to the eastern boundary of the site. Any views into the site along the southern-most portion of the eastern boundary are largely screened by vegetation (discussed above), and the vehicle speeds (100 km per hour) along Hopeland Road mean that there is limited time to capture views to the west into the site through sporadic gaps in the vegetation. However, the northern-most portion of the


OCM042.1/04/15





eastern boundary contains no screening by vegetation or other infrastructure, with views directly into the site across the cleared paddocks towards the sandy rise (and proposed sand extraction area). Views into the site from landholdings to the north and south are largely screened by remnant vegetation present within these landholdings, see Plate 6 and Plate 7, while views from the west are largely screened by Punrak Drain which is located adjacent to the western boundary of the site, see Plate 8.

5 Proposed extractive industry

5.1 Overview

The site has deposits of Bassendean Sand which are suitable for use as construction and fill sand, and is proposed to be extracted. The proposed sand extraction area is shown in Figure 7 and

Appendix B. The proposed sand extraction will encompass approximately 18.8 hectares of the site, and will support the extraction of sand for five to 10 years depending upon market demand for the resource.

The excavation of sand will generally involves the following, to be undertaken in stages across the proposed sand extraction area:

Vegetation clearing Topsoil removal and stockpiling Extraction operations Distribution of sand material Decommissioning and rehabilitation.

A summary of the proposed sand extraction activity within the site has been provided in Table 11

below, with further detail provided in the following sections.

5.2 Project description

5.2.1 Pre-Excavation Works

5.2.1.1 Clearing

There will be no vegetation clearing involved in the first 8 hectares of the proposed sand extraction area as this area does not support any vegetation.

There is limited remnant vegetation present within the site, with the majority of the site historically cleared and utilised for pasture and grazing. The north-eastern portion of the site contains areas of non-native trees that were planted historically as part of the agriculture land use within the site.

Limited areas (approximately 2.7 hectares) within the proposed sand extraction area are composed of remnant native species. Before these areas are cleared, Goodfeel will apply for a clearing permit (administered under Part V of the EP Act) to clear the remnant native species. These trees have been identified as ‘Parkland Cleared’, composed of scattered paddock trees over pasture weeds.

Clearing will involve the use of wheel loader or excavator to push over the trees, before they are mulched. The mulch will be stockpiled for use within the site.

5.2.1.2 Topsoil and overburden removal

The topsoil will be removed from the proposed sand extraction area using a wheel loader and/or excavator and pushed into windrows. Topsoil removal will be in stages, as the excavation process progresses.

Topsoil removal will comprise the first 100 mm to 300 mm of the soil being scraped and then stockpiled within the site for use as part of the decommissioning and rehabilitation process.

Topsoil and overburden will be stored adjacent to the area of excavation, or will be returned directly being behind the advancing face of the extraction area.

5.2.2 Excavation Method

Sand will be mined from the excavation area in a staged program with mining proposed to commence in early 2015. Each stage of the sand excavation is expected to be approximately 4 hectares in size.

The extraction pit will be designed to maintain a one metre separation between maximum depth of extraction and the AAMGL. This is shown in Figure 9 and Appendix B.

As part of the sand extraction process, the following is proposed:

The excavation work will commence from the south and move in a western and northern direction, towards the northern boundary of the site.

Prior to excavation, scattered paddock trees will be cleared and topsoil will be removed and stored for use in rehabilitation of the site.

If overburden is removed, it will be stockpiled for use in the future rehabilitation of the proposed sand extraction area. Overburden is generally not produced from sand extraction processes.

Sand will be extracted using a wheel loader and/or excavator to excavate the sand resource. If required, the sand resource will be screened using a portable screening plant to remove any

organic material. The sand will then be stockpiled prior to being tipped directly into road trucks for transportation.


OCM042.1/04/15





Reforming of the land is proposed to be undertaken using a wheel loader of excavator to push the topsoil into place.

On completion, the land surface will be graded to ensure the final slopes will not exceed 1 in 3 horizontal to vertical in accordance with Shire of Serpentine–Jarrahdale Extractive Industries Local Law 1999.

Rehabilitation will progressively follow excavation wherever possible.

5.2.3 Finished Levels

The excavation within the site proposes to lower the natural topography, and will involve the removal of the sandy rise located within the central portion of the site. The extraction is proposed to occur to a maximum depth of between 16.5 mAHD in the northern portion of the proposed sand extraction area and 18 mAHD in the southern portion of the proposed sand extraction area. This will provide a minimum separation of one metre from the AAMGL.

The proposed separation from groundwater is considered to be acceptable, given the site is not located within or nearby to priority drinking water source areas or other sensitive water resources and is unlikely to affect the water balance of ecology of natural lakes, swamps or wetlands with conservation values. As outlined in Section 4.13, the site supports Multiple Use Wetland values, which do not require specific management from a conservation perspective. Additionally, the proposed future land use of the site, which is intended to support agricultural-related activities, will not be impacted by the proposed separation. A one-metre groundwater separation between the surface of the land and groundwater levels is observed within the western portion of the site, which historically has supported agricultural-related activities. Overall, groundwater levels are generally declining within the broader area.

The finished levels have been shown within Figure 9 and Appendix B.

5.2.4 Hours of Operation/Duration

The proposed hours of operation will be from 7.00am and 5.00 pm Saturday inclusive.

5.3 Infrastructure and Access

5.3.1 Site Access

An existing access road into the site is comprised of compacted limestone, with access into the site to be via Hopeland Road, which is a public road. Site access is shown in Figure 8 and Figure 9 as well as Appendix B and Appendix C. The current access road will be maintained as the only site access for the proposed sand extraction activities.

The perimeter fencing currently surrounding the boundary of site will be maintained, with property gates to be locked outside operating hours to prevent public access to the site, as shown in Figure 9. Additional fencing may be erected internally along the north-eastern boundary of the proposed sand extraction area, to provide for windbreak planting/fencing.

5.3.2 Haulage

The number of trucks entering the site is likely to vary throughout the year, and will be dependent upon the demand for the sand resource. However, it is anticipated that on average between one to three trucks per hour will access the site during operating hours, with up to 20 trucks per day.


OCM042.1/04/15





The primary haulage routes are expected to be north and south along Hopeland Road onto Karnup Road and Lakes Road respectively, and then east or west to and from the Kwinana Freeway or South Western Highway. Goodfeel engaged TARSC to complete a traffic assessment for the site and proposed sand extraction. Based on the traffic assessment (TARSC 2014), the expected proportion of vehicular traffic along each of the primary haulage routes has been outlined in Table 12.

Table 12: Summary of vehicular traffic flow expected as a result of the proposed sand extraction

PROPOSED HAULAGE ROUTE PERCENTAGE OF TRAFFIC FLOW (%)

Karnup Road west of Hopeland Road 40

Karnup Road east of Hopeland Road 20

Lakes Road west of Hopeland Road 30

Lakes Road east of Hopeland Road 10

Hopeland Road north of the site 60

Hopeland Road south of the site 40

Overall, the proposed sand extraction within the site is expected to increase traffic flows along the three main routes by between one and three percent. TARSC indicated that average traffic flow can vary by up to five percent and as a result the average motorist is unlikely to notice any change in traffic volumes as a result of activities within the site. The proportion of heavy vehicles is expected to remain close to the current level of heavy vehicles observed along Hopeland Road, Karnup Road and Lakes Road.

The traffic assessment has been provided in Appendix E.

5.3.3 Infrastructure

The supporting infrastructure required for the proposed sand extraction activity will primarily involve the existing infrastructure and buildings currently present within the site, as shown in Figure 8 and

Figure 9 as well as Appendix B and Appendix C. The infrastructure and buildings within the site include:

A house, which will be used as site office and includes restroom facilities. The current restroom facilities will be maintained and are connected to a septic tank system. The septic tank system is located between the house and sheds.

Vehicles and equipment compound. This will include the sheds, with vehicle and equipment to be secured within the shed overnight and on weekends.

No refuelling facilities will be located within the site. Instead, a company that provides mobile fuelling facilities will be contracted to refuel plant and equipment within the site when required. This will include the use of a mobile fuelling truck, which will be fitted with a spill protection system to minimise potential for accidental discharges of hydrocarbons.

The site is supplied with mains electricity, accessed via the power transmission lines located adjacent to the eastern boundary of the site and it is anticipated that no other sources of power (i.e. generators) will be required.

It is possible that additional fencing will be installed, to provide for future windbreak fencing. No other infrastructure will be required to be installed.


OCM042.1/04/15





5.4 Safety

5.4.1 Operations

The activities undertaken in association with the extraction of sand from within the site will comply with all relevant legislation including:

Dangerous Goods Safety Act 2004. Mines Safety and Inspection Act 1994. Mines Safety and Inspection Regulations 1995. Occupational Health and Safety Act 1984. Occupational Health and Safety Regulations 1996. Shire of Serpentine-Jarrahdale Extractive industry Local Law 1999.

All operational personnel will be provided with site inductions, safety and environmental awareness training and in particular detail will be provided on management of the proposed sand extraction area within the boundaries shown in Figure 7. All workers will be required to wear full-time protective safety and high visibility work gear when within the site.

5.4.2 Signage

Goodfeel will place a sign stating ‘Danger Excavations Keep Out’ that is not less than 1.8 metres high and not less than one metre wide, in accordance with Provision 6.2 of the Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999. An indicative location for the signage has been shown in Figure 9 and Appendix B.

The signs will also indicate operation hours and contact details for the site manager.


OCM042.1/04/15





6 Management of environmental attributes and values

6.1 Overview

Section 6 is intended to provide an outline of the proposed framework for the management of environmental attributes and values within the site and proposed sand extraction area.

The site is predominantly composed of cleared paddocks, with scattered trees located within the northern portion of the proposed sand extraction area. These trees are composed of native and non-native species, with the native species isolated to the north-western portion of the proposed sand extraction area (approximately 2.7 hectares).

The finished surface level following extraction of the sand resource will be maintained to at least one-metre above the determined AAMGL within the site. The AAMGL has been determined based on thorough review of nearby groundwater data (provided by the Department of Water) and calculation of AAMGL based site specific monitoring data from a number of groundwater bores. The separation from groundwater is considered to be acceptable given, the AAMGL is based on a detailed consideration of site specific groundwater information and that the site is not located within or nearby to priority drinking water source areas or other sensitive water resources. The proposed separation of one metre is unlikely to affect the water balance of ecology of natural lakes, swamps or wetlands with conservation values.

6.2 Vegetation clearing

As part of the proposed sand extraction activities, approximately 33 remnant native trees will be cleared as well as a number of non-native planted trees. The native tree species likely to be cleared include:

One Allocasuarina fraseriana. One Eucalyptus rudis. Two Corymbia calophylla. Three Xylomelum occidentalis. 22 Eucalyptus marginata.

Emerge Associates completed a Level 1 flora and vegetation survey and found that the majority of the site was considered to be in ‘Completely Degraded’ condition due to historical clearing and extensive grazing that has resulted in the removal of most native flora species. Small scattered patches of vegetation were considered to be in ‘Degraded’ condition, as they contained several native species comprising both the overstorey and understorey layers and in which native flora species were not isolated occurrences. None of the areas in ‘Degraded’ condition are located within the proposed sand extraction area.

While the proposed sand extraction is unlikely to significantly impact on flora and vegetation values, as part of managing clearing of vegetation and potential impacts, the following actions will be undertaken:


Provision of a 20 metre separation between the proposed sand extraction area and the site boundary, in accordance with Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999.


OCM042.1/04/15





Within this separation area, a number of Eucalyptus marginata located adjacent to the northern boundary of the site will be retained.

Trees to be retained will be clearly marked with flagging tape. Vegetation that is cleared will be mulched within the site and stockpiled for use as part of

rehabilitation and/or dust management requirements. Topsoil will be stockpiled for use in rehabilitation of the proposed sand extraction area. Given the

topsoil mainly contains pasture weeds, the purpose of the stockpiled topsoil will be to assist in returning suitable agricultural topsoil (in terms of physical and chemical properties) to the post excavation areas.

A clearing permit application will be submitted to the DER for clearing of the native remnant tree species located within the north-western portion of the proposed sand extraction area. The area subject to the clearing permit application is shown in Figure 7. No clearing will occur within this area until the clearing permit is granted. As outlined in Section 4, the remainder of the trees within the sand extraction area are non-native planted trees and in accordance with the Environmental Protection (Clearing of Native Vegetation) Regulations 1997 are not considered to be ‘native vegetation’ and therefore no clearing permit is required.

6.3 Surface water and groundwater

The proposed extraction of sand is not expected to impact on surface water or groundwater quality, or groundwater levels within the site, or the surrounding areas.

As outlined within Section 4, the site is not located within or nearby to priority drinking water source areas or other sensitive water resources and is unlikely to affect the water balance or ecology of natural lakes, swamps or wetlands with conservation values. As outlined in Section 4.13, the site supports Multiple Use Wetland values, which do not require specific management from a conservation perspective.

Specifically, the hydrological functions of the site will be maintained as:

Groundwater recharge within the site is not expected to increase as a result of clearing scattered paddock trees within the northern portion of the proposed sand extraction area. The site is largely composed of cleared paddocks, which have limited impact on the surrounding groundwater levels.

No dewatering is proposed as part of the sand extraction process. At least a one-metre separation will be provided between the AAMGL and the ground surface as part of the sand extraction process.

Punrak Drain is an agricultural drain located along the western boundary of the site. This drain forms part of a network established by the State Government to assist in managing groundwater levels to provide productive agricultural areas. The drain will remain adjacent to the western boundary of the site

Water infiltrating within the proposed sand extraction area will be by direct rainfall run-off and is not expected to contain potential contaminants.

Due to the high porosity of the sandy soils within the site, no run-off is anticipated from the excavation area. Infiltration will remain the predominant drainage process within the site.

Any groundwater extraction within the site will be in accordance with the RIWI Act.


OCM042.1/04/15





The proposed sand extraction is unlikely to significantly impact on surface water and groundwater, or alter the hydrological functions of the site. However, as part of managing the sand extraction process, the following actions will be undertaken:

Undertake ongoing annual monitoring of groundwater levels within the site, utilising the monitoring bores shown in Figure 3.

Provide for at least one metre separation between AAMGL and the ground surface as part of the sand excavation process through the ongoing survey and control of the excavation process.

Commence rehabilitation works at the completion of each stage wherever possible. Maintain all plant equipment in good condition to minimise potential for contamination (from

accidental discharges of hydrocarbons). Maintain all haul roads in good condition with suitable grades to minimise potential for erosion

from rainfall.

If required, a groundwater licence for the extraction of groundwater for dust suppression purposes will be applied for by Goodfeel in accordance with the RIWI Act. Otherwise, water will be sourced from a water supply contractor.

6.4 Wetlands

Two wetlands occur within the site and are classified as a REW (with UFI 15364) and MUW (with UFI 15785). Based on a site specific survey the majority of the two wetlands within the site support vegetation determined to be in ‘Completely Degraded’ condition. A small portion of MUW UFI 15785 contains vegetation in ‘Degraded’ condition and is associated with two small areas that contain scattered Melaleuca preissiana over scattered Juncus pallidus, or Corymbia calophylla and Melaleuca preissiana over pasture weeds.

Emerge Associates undertook an evaluation of the wetland values for the portion of REW UFI No. 15364 within the site (in accordance with relevant guidelines) and found that the values within the site do not reflect any of the high level wetland values. The portion of REW UFI 15364 within the site would therefore be considered MUW.

MUWs contain few wetland attributes and are suitable for development if hydrological considerations are addressed appropriately. No specific separation distances are required between MUW areas and development (which in this case is the proposed sand extraction activities). None of the wetlands areas are proposed to be utilised for sand extraction as part of this development application, although sand extraction will occur adjacent to these areas. It is anticipated that groundwater levels will be maintained, and therefore the hydrological functions of the site will be maintained.

6.5 Separation distances and surrounding land uses

The surrounding land uses are predominantly rural, with the nearest dwellings located approximately 300 metres from the proposed sand extraction area, adjacent to the northern and southern boundaries of the site. The distance between the proposed sand extraction area and the nearest dwellings has been shown in Figure 10.

The Environmental Protection Authority (EPA) and DER approach to protecting the amenity of sensitive land uses from industrial land uses and their associated emissions is based on the following hierarchy:


OCM042.1/04/15





Avoidance of impacts. Individual industry to take all reasonable and practicable measures to prevent or minimise

emissions from their premises by implementing best practice. Ensure environmental impacts from industrial emissions are acceptable and meet the relevant

regulations and health criteria beyond the boundary of the site, industrial estate or buffer area.

There are a number of regulations and policies that have been implemented to support the objectives of the Environment Protection Act 1986. The EPA has also prepared various guidance documents, to assist in considering the potential impact on the environment from various activities.

Guidance for the Assessment of Environmental Factors No. 3 Separation Distances between Industrial and Sensitive Land Uses (EPA 2005) recognises that there is the potential for emissions (such as noise, gas, dust and odours) generated by a wide range of land uses, including industrial, commercial and rural activities and infrastructure, to exceed amenity levels considered acceptable in residential areas (and at other sensitive land uses), or pose a health risk to people. It was prepared by the EPA to provide advice on generic separation distances between specific industry and sensitive land uses, to support the planning process and identify the requirement for more detailed site specific investigations.

The generic separation distances detailed within Guidance for the Assessment of Environmental Factors No. 3 Separation Distances between Industrial and Sensitive Land Uses (EPA 2005) are not intended to be absolute separation distances but instead are a tool to assist in avoiding or minimising the potential for land use conflict by:

Identifying the need for a specific separation distance or buffer definition investigations. Providing general guidance on separation distances in the absence of site specific technical

studies.

Therefore, Guidance for the Assessment of Environmental Factors No. 3 Separation Distances between Industrial and Sensitive Land Uses (EPA 2005) can be used as a tool to determine when more information is required to demonstrate that an appropriate separation distances has been achieved.

In relation to sand extraction, the primary impacts likely to potentially exceed amenity levels considered acceptable in residential areas (and at other sensitive land uses), or pose a health risk to people are noise and dust. Guidance for the Assessment of Environmental Factors No. 3 Separation Distances between Industrial and Sensitive Land Uses (EPA 2005) recommends a separation distance of between 300 and 500 metres from sensitive uses, depending upon the size of the operation.

The proposed sand extraction within the site would not involve blasting or processing of sand, a part from transporting the sand from site. The low intensity nature and scale of the sand extraction works in addition to the onsite management of noise and dust, means that impacts on surrounding sensitive land uses is likely to be low. The majority of the sensitive land uses located in the vicinity of the site are located more than 300 metres from the proposed sand extraction area.

Overall:

The size of the operation is relatively small. No onsite processing of sand (apart from removing the organic matter), no crushing and no

screening is proposed as part of the sand extraction activities.


OCM042.1/04/15





On-site management for noise and dust will minimise potential impacts, this includes watering of the site during dry conditions and maintaining equipment in good working order. The proposed management of noise and dust has been summarised in Table 13.

Monitor and manage any complaints through a complaint register system. Rehabilitation of the site following the completion of sand excavation.

Table 13 below outlines the specific measures that will be employed by Goodfeel to manage potential impacts from noise and dust on sensitive land uses that may be generated from activities associated with the extraction of sand.

In addition, in the vicinity of the site are a number of poultry farms. Under EPA Guidance Statement No. 3 –Separation Distances between Industrial and Sensitive Land Uses (2005) poultry farms are identified as having similar impacts as sand extraction, however also indicates that odour is a consideration. The recommended separation distance from poultry farms to sensitive land uses if between 300 metres and 1000 metres, depending upon the size of the facility. A poultry farm is located within 500 metres of the site as well as nearby sensitive land uses (i.e. residences). The proposed sand extraction area is located a suitable distance from nearby sensitive land uses given the land use activities within the broader area (i.e. poultry farms) and the very low density of sensitive premises within the vicinity of the site.

6.6 Visual Impacts

No areas of high landscape amenity have been identified within the site.

Currently, the site is characterised by cleared paddocks, sporadically interspaced with trees of differing size and species, with the majority of these located in the background views from Hopeland Road. The eastern boundary of the site is largely composed of remnant native species, with approximately 300 metres of the 400 metre frontage to Hopeland Road composed of remnant vegetation screening.

The site forms part of a natural high point within the surrounding landscape, with the surrounding areas generally located within flatter areas of the landscape. These areas area also largely composed of cleared paddocks with interspaces trees. Directly north and south of the proposed sand extraction area, with the adjacent landholdings, are areas of remnant vegetation. These areas are located on portions of the sandy rise that is also located within the site. As the site has been historically cleared (unlike the adjacent areas that contain intact remnant vegetation), excavation of the sandy rise within the site and clearing of the scattered trees is unlikely to significantly change the views associated with this portion of the landscape.

To minimise the visual impact of the proposed sand extraction, the following will be implemented:

Provide additional planting along the site boundary directly adjacent to Hopeland Road, as shown in Figure 9. This planting is proposed to be comprised of native species, similar to those identified within the Level 1 flora and vegetation survey and in accordance with the planting guideline prepared by the Shire of Serpentine-Jarrahdale (see ‘Keeping it Local’ (Shire of Serpentine-Jarrahdale)).

Retain vegetation located outside the proposed sand extraction area. Where possible, retain trees along the boundary of the proposed sand extraction area and/or plant windbreak vegetation.


Minimise the amount of open ground at any one time. Where possible, position the topsoil stockpiles so they form screening barriers to the extraction

activities.

6.7 Dieback and weed management

6.7.1 Dieback

Phytophthora cinnamomi, commonly known as ‘Phytophthora Dieback’ is a soil borne fungal pathogen which is a serious threat to the flora of Western Australia. It is recognised as a threat within the Shire of Serpentine-Jarrahdale, particularly areas of remnant Banksia and Jarrah woodland.

Phytophthora Dieback is spread through surface and sub-surface water flows and soil movement. Consequently the movement of infested water and soil is key mechanism for how this pathogen is spread. Human activities such as road building, earth moving, timber harvesting, wildflower picking, bush walking, four wheel driving, firebreak management and planting of diseased nursery stock have contributed significantly to the rapid and widespread distribution of the pathogen (Dieback Working Group 2008; Centre for Phytophthora Science and Management 2008).


OCM042.1/04/15





Phytophthora Dieback is unlikely to be a risk within the site due the significant historic disturbance, with no intact native remnant vegetation located within the site. There are areas of remnant vegetation located adjacent to the northern and southern boundary of the site which may be at risk from Phytophthora Dieback. However, these areas are not located down gradient of the proposed sand extraction activities, thus the risk of introducing or spreading Phytophthora Dieback is minimal.

To minimise the introduction of dieback, the following actions will be undertaken:



Ensure machinery and equipment arrive on site soil free, or provide wash-down areas for vehicles that require cleaning.

Limit duplication of existing access ways. For screening vegetation and rehabilitation, purchase plant species from nurseries with a Nursery

Industry Accreditation.

6.7.2 Weeds

Weeds are recognised as a major contributor to the degradation of remnant vegetation areas and conservation areas. Weeds often prevent successful rehabilitation of areas and as such weed species require control in order to maintain natural areas and the ecological integrity of these areas. The Environmental Weed Strategy for Western Australia (CALM 1999) was developed in recognition of these species and the environmental impacts that often result from the presence of a specific weed species.

The site (and broader area) is already highly disturbed and is largely composed of a number of paddock weed species. It is unlikely that the proposed sand extraction within the site will introduce further weed species or that through the rehabilitation of the additional weed species will be introduced to the site or broader area.

However, to minimise the potential introduction of additional weed species, the following will be undertaken:



Ensure machinery and equipment arrives on site free of soil and organic material, or provide wash-down areas for vehicles that require cleaning.

For screening vegetation and rehabilitation, purchase plant species from nurseries with a Nursery Industry Accreditation.

Monitor for introduction of additional weed species, particular those identified as a Declared Plant (in accordance with Biosecurity and Agriculture Management Act 2007). If identified, these will be controlled and/or removed from the site.


OCM042.1/04/15





7 Decommissioning and Rehabilitation

Sand extraction is generally a short-term activity, that if not managed appropriately can create a variety of environmental and amenity impacts before, during and after extraction operations that vary from minimal to significant. An important part of managing impacts is successful decommissioning and rehabilitation of the site.

As outlined earlier, the site is predominantly composed of cleared paddocks, with scattered trees located within the northern portion of the proposed sand extraction area. These trees are comprised of native and non-native species, with native species isolated to the north-western portion of the proposed sand extraction area.

Goodfeel propose to decommission and rehabilitate the site and return the land to agricultural pasture, suitable for grazing, which is in accordance with the current use of the site and the ‘Rural’ zoning of the site under the MRS and Shire of Serpentine-Jarrahdale TPS No. 2.

In decommissioning and rehabilitating the site, Goodfeel will ensure the following principles are adopted:

Future public health and safety are not compromised. Environmental resources are not subject to physical and chemical deterioration. Post-extraction use of the site is beneficial and sustainable in the long-term. Any adverse socio-economic impacts are minimised, with opportunities taken to maximise socio-

economic benefits. The post-mined landscape is safe and stable from a physical, geochemical and ecological

perspective. The quality of surrounding water resources is protected. The agreed sustainable post-mining land use is established and clearly defined to the satisfaction

of the community and local government.

7.1 Decommissioning

Upon final completion of the sand extraction, all vehicles and equipment required for the sand extraction activities will be removed from site. As the proposed sand extraction activity is utilising exiting facilities and infrastructure, these will remain within the site and will only be removed if they are not considered suitable ongoing use.

The land surface within the proposed sand extraction area will be graded to ensure that the final slopes will not exceed 1 in 3 horizontal to vertical side slope in accordance with Shire of Serpentine–Jarrahdale Extractive Industries Local Law 1999. These batter areas will be stabilised with ground cover (i.e. mulch or similar) and where appropriate vegetation.

The access track will be retained, as it follows the current access into the site. It is possible that some areas of the access track may be modified or removed, depending upon the future use of the site.


OCM042.1/04/15





7.2 Rehabilitation

The rehabilitation of the site is intended to return the land to a condition suitable to support, as a minimum, activities that are currently supported by the site which include grazing and pasture cropping.

As part of the rehabilitation process, the following will be undertaken:

Establish topographic contours. The final contours are anticipated to be visually compatible with the flatter parts of the site. For the portion of the sandy rise that will be excavated but intersects with the landholdings to the north and south, suitable batters (no greater than 1 in 3) will be created that minimise the potential for erosion.

All final slopes will be similar to those in the local area and the excavation will be left in a safe manner, in accordance with the Mines Safety and Inspection Act 1994.

Batter areas will be stabilised to minimise the potential for erosion. This may include use of mulch that was stockpiled as part of clearing works (where available) or biodegradable matting (i.e. jute matting or similar). Where appropriate, stabilisation of the batter areas may include the planting of native species, similar to those identified within the Level 1 flora and vegetation survey and in accordance with the planting guideline prepared by the Shire of Serpentine-Jarrahdale (see ‘Keeping it Local’).

Re-spread topsoil stockpiled as part of the clearing works. The topsoil will be spread to a depth of 100 mm and deep ripped to a depth of 300mm to assist in establishment of pasture species. Where required, seed for pasture will be spread to maximise growth and ensure 90 per cent vegetation cover is achieved.

Goodfeel will undertake, manage and fund the rehabilitation program. Given Goodfeel is also the land owner they will carry the ultimate and ongoing responsibility for the management of the site and therefore will not be able to avoid these rehabilitative obligations.


OCM042.1/04/15





8 Conclusions

Goodfeel is proposing to extract sand from the site. The sand resource is proposed to be extracted from approximately 18.8 hectares of the site (referred to as the ‘proposed sand extraction area’), and encompasses the sandy rise that is located within the site. The proposed sand extraction is intended to supply a basic raw material that will be used for a variety of purposes such as clean fill sand and construction sand, to support infrastructure and urban development throughout the broader region. Depending upon demand, it is estimated that the sand resource will support mining for five to 10 years within the site.

The site is zoned ‘Rural’ under the Metropolitan Region Scheme (MRS) and ‘Rural’ under the Shire of Serpentine-Jarrahdale Town Planning Scheme (TPS) No. 2. It is also located within the ‘Poultry Farm Special Control Area’ under Shire of Serpentine-Jarrahdale TPS No. 2. Under the ‘Rural’ zone, sand extraction is considered to be ‘Industry-Extractive’ and is a discretionary land use in ‘Rural’ zoned areas.

Emerge Associates were engaged by Goodfeel to provide consultancy services to support the preparation of a Development Approval (DA) application and Extractive Industry Licence (EIL) application to facilitate the extraction of the sand resource. This document has been prepared outline:

The planning context and the environmental attributes and values associated with the site The proposed sand extraction process Management of potential impacts associated with the proposed sand extraction Decommissioning and rehabilitation following extraction of the sand resource.

The proposed extraction of sand meets the broader land use considerations of the WAPC and the Shire of Serpentine-Jarrahdale, by maximising the use of the sand resource, while ensuring that the sand extraction operation will not impact adversely on the environment or amenity of surrounding landholdings. Overall, the proposed sand extraction is unlikely to significantly impact environmental attributes or values, or nearby land uses as:

The site is currently cleared of intact remnant vegetation and largely composed of grazed paddocks. A number of remnant native trees species will be cleared, however these trees do not form areas of intact remnant vegetation nor are they utilised significantly by conservation significant fauna.

The current hydrological functions of the site will be maintained, primarily through limiting the vertical extent of sand extraction.

It is located within an area designated for poultry farms, with horse agistment, grazing and poultry farming the predominant land uses within the broader area. The proposed sand extraction is not expected to impact nearby sensitive land uses to a greater extent than the poultry farms in the broader area.

Section 4 and Section 6 of the document provide detail on the environmental attributes and values identified within the site, and how the proposed sand extraction within the site will be managed. A summary of the management actions has been provided below in Table 14.


OCM042.1/04/15





Table 14: Summary of management actions


Vegetation Apply for a clearing permit pursuant to Part V of the Environmental Protection Act 1986 (EP Act) to clear a number of remnant native species within the north-western portion of the proposed sand extraction area. These trees are identified as ‘Parkland Cleared’, composed of scattered paddock trees over pasture weeds.


Trees located within 20m of the proposed sand extraction area that are to be retained will be clearly marked with flagging tape.

Vegetation that is cleared will be mulched within the site and stockpiled for use as part of rehabilitation and/or dust management requirements.

Topsoil will be stripped and stockpiled for use in rehabilitation of the proposed sand extraction area.

Surface water and groundwater

Apply for groundwater licence to access groundwater for dust suppression purposes. Undertake annual ongoing monitoring of groundwater levels within the site, utilising the monitoring bores

shown in Figure 3. Provide at least one metre separation between the determined AAMGL and the post extraction ground

surface as part of the sand excavation process. Commence rehabilitation works at the completion of each stage wherever possible. Maintain all plant equipment in good condition to minimise potential for contamination (from accidental

discharges of hydrocarbons). Avoid excavation, vehicle movements or material stockpiling within 50 metres of the drain. Maintain all haul road surfaces in good condition with suitable grades to minimise potential for erosion

from rainfall.

Wetlands Provide at least one metre separation between the determined AAMGL and the post extraction ground surface as part of the sand excavation process.

Separation distances

No onsite processing of sand, including no crushing and no screening, is proposed as part of the sand extraction activities.

On-site management for noise and dust will minimise potential offsite impacts, including watering of the site during dry conditions and maintaining equipment in good working order. The management of noise and dust has been summarised in Table 13.

Monitor and follow-up complaints through a complaint register system. Rehabilitation of the site following the completion of sand excavation.

Visual impacts Provide additional planting along the site boundary directly adjacent to Hopeland Road, as shown in Figure 9.


Minimise the amount of open ground at any one time through staged excavation and rehabilitation. Where possible, position topsoil stockpiles to form screening barriers to the extraction activities.

Dieback and weed management



Ensure machinery and equipment arrive on site soil free, or provide wash-down areas for vehicles that require cleaning.

Limit duplication of existing access ways. For screening vegetation and rehabilitation, purchase plant species from nurseries with a Nursery

Industry Accreditation. Monitor for introduction of additional weed species, particular those identified as a Declared Plant (in

accordance with Biosecurity and Agriculture Management Act 2007). If identified, these will be controlled and/or removed from the site.


OCM042.1/04/15






Decommissioning All vehicles and equipment required for the sand extraction activities will be removed from site. Retain existing facilities and infrastructure within the site, unless determined to be unsuitable for the

future land use. Batter areas to be graded in accordance with Shire of Serpentine–Jarrahdale Extractive Industries Local

Law 1999. These batter areas will be stabilised with ground cover (i.e. mulch or similar) and where appropriate vegetation.

Rehabilitation Establish topographic contours to be compatible with existing contours within portions of the site not excavated.

Stabilise batter areas to minimise the potential for erosion as a maximum of 1 to 3 side slopes. Re-spread topsoil stockpiled as part of the clearing works. The topsoil will be spread to a depth of 100

mm and deep ripped to a depth of 300mm to assist in establishment of pasture species. Where required, seed for pasture will be spread to maximise growth and ensure 90 per cent pasture

cover is achieved

This report has addressed the requirements of the Shire of Serpentine-Jarrahdale Extractive Industry Local Law 1999 and Info Note PS06 – Guidelines for Extractive Industries and detailed information relevant for both a DA application and EIL application. The sand extraction activities can be managed appropriately so that they will not significantly impact on the environmental attributes and values of the site or the surrounding land uses.

PROJECT NAME Hopelands Industry Licence Support PROJECT NUMBER EP14-057(01)

DATE 24/11/2014 PURPOSE Baseline survey of flora, vegetation and wetland values

present within Lot 371 Hopelands Road, Hopelands

CIRCULATION Jason Hick and Kirsten Knox

DETAILS OF MEMORANDUM

Introduction

Lot 371 Hopelands Road in Hopelands (‘the site’) is owned by Goodfeel Enterprises Pty Ltd and portions of the

site are proposed for sand extraction purposes. This memorandum was prepared to document the results of a

baseline, Level 1 flora and vegetation assessment (in accordance with EPA Guidance Statement Number 51 -

Terrestrial flora and vegetation surveys for environmental impact assessment in Western Australia (EPA 2004))

and an assessment of the wetland values present.

Background

Regional Soils and Landform

The site occurs on the Swan Coastal Plain which is a geomorphic entity approximately 20-30 km wide. The site

forms part of the Southern River geomorphological unit, which comprise sandplains with low dunes and many

intervening swamps; iron and humus podzols, peats and clays (Churchward and McArthur 1980). The Southern

River unit occurs at the junction of the Bassendean and Guildford major geological systems (Playford et al.

1976).

Regional vegetation

The site lies within the Swan Coastal Plain Interim Biogeographic Regionalisation for Australia (IBRA) region

(Thackway and Cresswell 1995). The Swan Coastal Plain IBRA region is broadly compatible with the Swan

Coastal Plain (Drummond Botanical Subdistrict) Phytogeographical Subregion as described by Beard (1990).

This region is characterised by Banksia low woodlands on leached sands, woodlands of tuart (Eucalyptus

gomphocephala), jarrah (Eucalyptus marginata) and marri (Corymbia calophylla) on less leached soils and

Melaleuca swamps.

At a local level, vegetation complex mapping for the Swan Coastal Plain undertaken by Heddle et al. (1980)

indicates that the site is mapped within the Southern River vegetation complex. Vegetation complex mapping is

based on soil, geomorphology and water availability patterns. The Southern River complex is described as

containing ‘open woodland of Corymbia calophylla - Eucalyptus marginata - Banksia spp. with fringing woodland

of Eucalyptus rudis - Melaleuca rhaphiophylla along creek beds’ (Heddle et al. 1980).

Remnant vegetation extent according to vegetation complexes statistics have been published by the Local

Biodiversity Program through the Western Australian Local Government Association (WALGA). These statistics

indicate that the pre-European extent of the Southern River complex on the Swan Coastal Plain was 57,171 ha.

As of 2013, 11,255 ha (19.7%) of this remains and 6.6% is under some form of protection. Review of aerial

photography indicates that virtually no intact vegetation remains within the site thus there is no remaining

representation of this vegetation complex.


OCM042.1/04/15

Significant Flora Species

At a state level, plant species acquire ‘Threatened’ or ‘Priority’ conservation status where populations are

restricted geographically or threatened by local processes. DPaW recognise these threats and subsequently

considers population protection and species conservation. DPaW enforces the Wildlife Conservation Act 1950

(WC Act) to conserve Threatened flora and protect all populations. Threatened flora are gazetted under

subsection 2 of section 23F of the WC Act and it is an offence to “take” or damage rare flora without Ministerial

approval. Section 23F of the Act defines “to take” as “… to gather, pluck, cut, pull up, destroy, dig up, remove or

injure the flora to cause or permit the same to be done by any means”.

Priority flora species are potentially rare or threatened and are classified in order of threat, however are not

afforded direct statutory protection. The definition and categories of Threatened and Priority Flora are listed in

Table 1.

Table 1: Definition of Threatened and Priority Flora Species (Smith 2010)

CONSERVATION CODE

CATEGORY

T

Threatened Flora – Extant Taxa

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.

X

Threatened Flora – Presumed Extinct Taxa

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.

P1

Priority One – Poorly Known Taxa

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.

P2

Priority Two – Poorly Known Taxa

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 urgently need further survey.

P3

Priority Three – Poorly Known Taxa

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 needs further survey.

P4

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.

A search was conducted of DPaW’s databases for Threatened and Priority Flora and the EPBC Act list of

Matters of National Environmental Significance (MNES) that occur within the wider local area and the results are

listed in Table 2.

Threatened Ecological Communities (TEC’s) and Priority Ecological Communities (PEC’s)

In Western Australia, Threatened Ecological Communities (TECs) are determined by the Western Australian

Threatened Ecological Communities Scientific Advisory Committee (WATECSAC) and endorsed by the Minister

for the Environment. The WATECSAC is an independent group comprised of representatives from organisations

including tertiary institutions, WA Museum and DPaW. Communities can be assigned to one of the categories


OCM042.1/04/15

outlined in Table 3 relating to their status of threat. While they are not afforded direct statutory protection at a

state level (unlike Threatened Flora under the WC Act) their significance is acknowledged through other state

environmental policies and approval processes such as Environmental Impact Assessment pursuant to Part IV of

the Environmental Protection Act 1986 (EP Act) and the Part V EP Act Clearing Regulations.

In addition to listing as a TEC, a community may be listed as a Priority Ecological Community (PEC). This is an

ecological community that is under consideration for listing as a TEC, but does not yet meet survey criteria or has

not been adequately defined, and can be placed on the list of PECs in either Category 1, 2 or 3 (these are

described in Table 4). Ecological communities that are adequately known and are rare but not threatened, or

meet criteria for “Near Threatened”, or that have been recently removed from the Threatened list, are placed in

Priority 4. These ecological communities require regular monitoring. Conservation dependent ecological

communities are placed in Priority 5 (DEC 2009).

Threatened Communities are afforded statutory protection at a Federal level pursuant to the EPBC Act. The

EPBC Act provides for the protection of ecological communities, which are listed under section 181 of the Act.

They are categorised as ‘Critically Endangered’, ‘Endangered’ or ‘Vulnerable’.

Table 3: Categories of Threatened Ecological Communities (English and Blyth 1997)

CONSERVATION CATEGORY DESCRIPTION

PD Presumably Totally Destroyed

An ecological community that has been adequately searched for but for which no representative occurrences have been located.

CE Critically Endangered

An ecological community that has been adequately surveyed and is found to be facing an extremely high risk of total destruction in the immediate future.

E Endangered

An ecological community that has been adequately surveyed and is not critically endangered but is facing a very high risk of total destruction in the near future.

V Vulnerable

An ecological community that has been adequately surveyed and is not critically endangered or endangered but is facing a high risk of total destruction or significant modification in the medium to long-term future.

Table 4: Categories of Priority Ecological Communities (DEC 2009)

PRIORITY CATEGORIES DESCRIPTION

Priority 1 Ecological communities with apparently few, small occurrences, all or most not actively managed for conservation (e.g. within agricultural or pastoral lands, urban areas, active mineral leases) and for which current threats exist. Communities may be included if they are comparatively well-known from one or more localities but do not meet adequacy of survey requirements, and/or are not well defined, and appear to be under immediate threat from known threatening processes across their range.

Priority 2 Communities that are known from few small occurrences, all or most of which are actively managed for conservation (e.g. within national parks, conservation parks, nature reserves, State forest, unallocated Crown land, water reserves, etc.) and not under imminent threat of destruction or degradation. Communities may be included if they are comparatively well known from one or more localities but do not meet adequacy of survey requirements, and/or are not well defined, and appear to be under threat from known threatening processes.

Priority 3

Communities that are known from several to many occurrences, a significant number or area of which are not under threat of habitat destruction or degradation or:

(i) communities known from a few widespread occurrences, which are either large or within significant remaining areas of habitat in which other occurrences may occur, much of it not under imminent threat, or;

(ii) communities made up of large, and/or widespread occurrences, that may or not be represented in


OCM042.1/04/15

PRIORITY CATEGORIES DESCRIPTION

the reserve system, but are under threat of modification across much of their range from processes such as grazing by domestic and/or feral stock, and inappropriate fire regimes.

Communities may be included if they are comparatively well known from several localities but do not meet adequacy of survey requirements and/or are not well defined, and known threatening processes exist that could affect them.

Priority 4

Ecological communities that are adequately known, rare but not threatened or meet criteria for Near Threatened or that have been recently removed from the threatened list. These communities require regular monitoring.

Priority 5

Ecological communities that are not threatened but are subject to a specific conservation program, the cessation of which would result in the community becoming threatened within five years.

Selected TECs are also afforded statutory protection at a Federal level pursuant to the EPBC Act. The EPBC

Act provides for the protection of TECs, which are listed under section 181 of the EPBC Act, and are defined as

“Critically Endangered”, “Endangered” or “Vulnerable” under Section 182.

A search was conducted of the EPBC Act list of MNES which indicated the presence of three federally listed TECs

within 5 km of the site. These are listed in Table 5. Comparisons with state listed TECs and PECs have been

undertaken based on the vegetation present within the site.

Wetlands

Wetlands in Western Australia are defined as “areas of seasonally, intermittently or permanently waterlogged

soils or inundated land, whether natural or otherwise, fresh and saline, e.g. waterlogged soils, ponds, billabongs,

lakes, swamps, tidal flats, estuaries, rivers and the tributaries” (Wetlands Advisory Committee 1977). This

definition has been adopted by Semeniuk (1987) and by V & C Semeniuk Group for the purposes of wetland

mapping and classification on the Swan Coastal Plain (Hill et al. 1996).

DPaW (formally known as Department of Environment and Conservation) digitised the original Hill et al. (1996)

mapping to form the Geomorphic Wetland Swan Coastal Plain Dataset, which categorises the individual

wetlands into specific management categories as described in Table 6.


OCM042.1/04/15

Table 6: Wetland management categories and management objectives (WAPC 2005)

MANAGEMENT CATEGORY

DESCRIPTION OF WETLAND MANAGEMENT OBJECTIVES

Conservation (CCW) Supports high levels of attributes and functions

Preserve wetland attributes and functions through reservation in national parks, crown reserves and state owned land. Protection provided under environmental protection policies.

Resource Enhancement (REW)

Partially modified but still supporting substantial functions and attributes

Restore wetland through maintenance and enhancement of wetland functions and attributes. Protection via crown reserves, state or local government owned land, environmental protection policies and sustainable management on private properties.

Multiple Use (MUW) Few wetland attributes but still provide important hydrological functions

Use, development and management considered in the context of water, town and environmental planning through land care.

A review of the area indicates the presence of part of two mapped Geomorphic Wetlands within the Geomorphic

Wetlands of the Swan Coastal Plain dataset; there were Resource Enhancement Wetland (REW) Unique

Feature Identifier (UFI) No. 15364 (a dampland) and Multiple Use Wetland (MUW) UFI 15785 (a palusplain)

(DPaW 2014). The wetlands within the site are shown on Figure 1 and 2.

REW UFI No. 15364 is an extensive wetland occupying 2635 ha extending out to the east of the site. Review of

aerial photography indicates that much of the area covered by this REW retains limited native vegetation.

The wetlands within the site form part of the Bennett Brook consanguineous suite, of which 7.7% is classified as

Conservation Category Wetlands (CCWs) (DPaW 2013).

Fauna Habitat

In addition, three small areas on the periphery of the site to the north and south are mapped as potentially

containing Carnaby’s black cockatoo foraging habitat (DEC 2011). These identified patches of potential

Carnaby’s black cockatoo foraging habitat extend and cover larger areas of intact vegetation that occur to the

north and south of the site, as shown on Figure 1 and 2.

Methodology

A botanist and environmental consultant and from Emerge Associates visited the site on 22 October 2014 to

undertake an assessment of the flora, vegetation and wetland values present within the site. The site was

traversed by vehicle and on foot and vegetation present within the site was recorded and mapped. Relevant site

features were photographed.

The condition of the vegetation was assessed to assist in determining the conservation values of the site. The

vegetation condition was rated according to Keighery (1994), a vegetation condition scale commonly used in the

Perth Metropolitan Region, but which is also appropriate for other urban and peri-urban areas. The categories

are listed and defined in Table 7 (Keighery 1994).

Table 7: Vegetation Condition Scale (Keighery 1994).

VEGETATION CONDITION DEFINITION

Pristine Pristine or nearly so, no obvious signs of disturbance.

Excellent Vegetation structure intact, disturbance affecting individual species and weeds are non-aggressive species.

Very Good Vegetation structure altered obvious signs of disturbance. For example, disturbance to vegetation structure caused by repeated fires, the presence of some more aggressive weeds, dieback, logging and grazing


OCM042.1/04/15

VEGETATION CONDITION DEFINITION

Good Vegetation structure significantly altered by very obvious signs of multiple disturbances. Retains basic vegetation structure or ability to regenerate it. For example, disturbance to vegetation structure caused by very frequent fires, the presence of some very aggressive weeds at high density, partial clearing, dieback and grazing.

Degraded Basic vegetation structure severely impacted by disturbance. Scope for regeneration but not to a state approaching good condition without intensive management. For example, disturbance to vegetation structure caused by very frequent fires, the presence of very aggressive weeds, partial clearing, dieback and grazing.

Completely Degraded The structure of the vegetation is no longer intact and the area is completely or almost completely without native species. These areas are often described as ‘parkland cleared’ with the flora comprising weed or crop species with isolated native trees or shrubs.

Survey Results

Flora

The native species listed in Table 8 were recorded within the site. No Threatened or Priority Flora species were

found to occur within the site, nor are any considered likely to occur due to the high level of historical disturbance

and widespread weed invasion which has resulted in the removal of almost all native understorey species.

Vegetation

The site visit indicated the presence of numerous areas containing native flora species across the site. The vast

majority of these areas however consisted of ‘Parkland Cleared’ native trees over a pasture weed dominated

understorey and were thus not considered to constitute ‘intact’ plant communities. The areas of vegetation within

the site are described below and shown on Figure 1.

P - Planted non-endemic trees over pasture weeds (Plate 9).

An additional vegetation type was noted just outside of the eastern site boundary adjacent to Hopelands Road

and was described as CcMpKa - Remnant Corymbia calophylla and Melaleuca preissiana with occasional Kingia

australis over pasture weeds (Plate 10). This vegetation type is likely to have once represented FCT 3a –

Corymbia calophylla – Kingia australis woodlands on heavy soils which is a state and federally listed TEC,

however was in ‘Degraded’ condition and thus is unlikely to currently represent this TEC.

Owing to the significantly compromised condition, no vegetation types within the site can be determined or

considered likely to represent any other TECs or PECs.

Vegetation Condition

The majority of the site was considered to be in ‘Completely Degraded’ condition owing to historical clearing and

extensive grazing that has resulted in the removal of most native flora species. The ‘Completely Degraded’ areas

of the site include some areas containing scattered or isolated native trees such as Corymbia calophylla,

Melaleuca preissiana and Eucalyptus marginata. Some small scattered patches were considered to be in

‘Degraded’ condition, as they contained several native species comprising both the overstorey and understorey

layers and in which native flora species were not isolated occurrences. The areas of ‘Degraded’ vegetation

comprise remnant Melaleuca preissiana over scattered patches of Juncus pallidus over pasture weeds, open


OCM042.1/04/15

woodland of Eucalyptus rudis and Melaleuca preissiana over sedgeland of Juncus pallidus and remnant

Corymbia calophylla and Melaleuca preissiana over pasture weeds. No vegetation was considered to be in

‘Good’ or better condition. Vegetation condition across the site is shown on Figure 2.

Wetlands

The portion of REW UFI No. 15364 within the site was largely in ‘Completely Degraded’ condition, excepting

some small patches of vegetation type CcMp and MpJp. The vegetation type CcMpKa occurred just to the west

of the site and was within the mapped extent of REW UFI No. 15364.

Based on the evaluation of the wetland values of the portion of REW UFI No. 15364 within the site using DPaW’s

evaluation methodology (DPaW 2013), the wetland did not meet any of the preliminary evaluation criteria (which

would lead to an automatic assignment of CCW) thus the secondary evaluation was used. Given the large size of

the REW, it was deemed acceptable to evaluate the section of the wetland just within the site. The secondary

evaluation led to a score of:

Three high level attributes

Four intermediate level attributes

Eight low level attributes.

The three high level attributes are all at the regional scale and related to:

<20% of wetlands in the same consanguineous suite (Bennett Brook) are assigned Conservation by

area

<20% of wetlands of the same type (dampland) in the same consanguineous suite (Bennett Brook) are

assigned Conservation by area

The wetland is identified in a vegetation complex (Southern River Complex) which is represented by

<30% of the pre-European extent.

Due to the condition of the wetland area and the historic loss of virtually all native wetland vegetation, the portion

of REW UFI No. 15364 does not reflect any of these high level values. The most appropriate management

category for the portion of REW UFI No. 15364 within the site was considered to be MUW based on the results of

the evaluation.

Fauna Habitat

The small patches of the site mapped as containing potential Carnaby’s black cockatoo foraging habitat

occurring on the periphery of the site (shown on Figure 1 and 2) were in ‘Degraded’ or ‘Completely Degraded’

condition. The southern area contained largely planted non-native trees (vegetation type P), with a small area

containing vegetation type EgCc in ‘Degraded’ condition (containing five native trees). The north-eastern patch

includes a small area of vegetation type CcMp in ‘Degraded’ condition, whilst the north western patch includes

one Eucalyptus marginata tree on the periphery of the site, this area was in ‘Completely Degraded’ condition.

Much more significant potential foraging habitat occurs to the north and south of the site which is more likely to

be used by species of black cockatoo.

Outside of the mapped potential foraging habitat, the site contained a number of tree species that are commonly

foraged by species of black cockatoo (c. 26 Eucalyptus marginata, three Eucalyptus gomphocephala and c. 15

Corymbia calophylla); however these were contained within Parkland Cleared, ‘Completely Degraded’

vegetation, with the remnant trees all that remained of the original plant assemblages. A number of these trees

had a Diameter at Breast Height (DBH) greater than 500 mm, and thus could potentially be used for breeding by


OCM042.1/04/15

species of black cockatoo; however again these were located within areas of ‘Completely Degraded’ vegetation

and were not associated with intact foraging habitat likely to support a population of black cockatoos.

Foraging evidence on Corymbia calophylla fruit within the site was predominantly from the common Red-capped

parrot, with some old foraging evidence noted from the forest red-tailed black cockatoo within vegetation type

EgCc in the south eastern corner of the site, this area contained three Eucalyptus gomphocephala and two

Corymbia calophylla trees). Vegetation type CcMpKa located outside of the site along Hopelands Road was

found to contain foraging evidence on Corymbia calophylla fruit from all three species of black cockatoo

(Carnaby’s, Baudin’s and Forest red-tailed black cockatoo).

Discussion

No Threatened or Priority Flora species, TECs or PECs are considered likely to occur within the site due to the

high level of historic disturbance and the loss of the vast majority of flora species and intact vegetation structure.

The most intact vegetation within the site was in ‘Degraded’ condition.

Eucalyptus gomphocephala (Tuart) was recorded in the south eastern corner of the site, represented by three

large individuals. This species is largely restricted to the two coastal Aeolian dune systems, the Quindalup Dunes

and the Spearwood Dunes, however outlying population shave been recorded near the Murray, Serpentine,

Swan and Canning Rivers. Given this distribution, the Tuart trees within the site are unlikely to be remnant. They

are however, very large trees that would have been planted between 50-100 years ago.

Whilst REW UFI No. 15364 contains its original soils and topography and is thus is likely to retain some

hydrological function (such as flood attenuation, recharge/discharge and hydrological storage), the wetland

vegetation has been almost completely removed, with occasional remnant trees and some small patches in

‘Degraded’ condition all that remains. As such, MUW is considered to the most representative wetland

classification. The portion of this REW extending outside of the site to the east is similarly highly disturbed and is

largely used for agricultural purposes.

Whilst species of black cockatoo have the potential to utilise the remnant trees within the site for foraging and

potentially also for roosting and breeding, these trees are unlikely to constitute a large proportion of habitat, and

the adjacent patches of vegetation, to the north and south of the site, are far more likely to be utilised.

Conclusions

Based on this baseline assessment, the site was not considered to contain any significant values related to flora,

vegetation and wetlands. Similarly, whilst a targeted fauna assessment has not been undertaken over the site, it

is not considered likely that the site is used by any fauna species to any high degree owing to the loss of virtually

all intact vegetation.

Excellence in Transport Engineering

Attention: David Woo

19th November 2014 Dear David RE: Lot 371 Hopeland Road Sand Quarry

I refer to your request to provide assistance in the provision of a transport assessment for the proposed sand quarry at Lot 371 in Hopeland Road. The expected routes to and from the proposed sand quarry are expected to be via Hopeland Road north and south onto Karnup Road and Lakes Road to then travel east or west to and from Kwinana Freeway or South Western Highway. If there are to be any local trips, then these may be via the local road network, such as Punrak Road, Utley Road, Henderson Road etc. Apart from these local trips all other trips are expected to be via the higher order, Hopeland Road, Karnup Road and Lakes Road. The expected proportions of vehicular traffic flows splits to and from the quarry are:

Karnup Road west of Hopeland Road 40% Karnup Road east of Hopeland Road 20% Lakes Road west of Hopeland Road 30% Lakes Road east of Hopeland Road 10% Hopeland Road north of the quarry 60% Hopeland Road north of the quarry 40%

From this, it can be seen that 60% of trips are expected to and from the north, whilst 40% are expected to and from the south. Current Traffic movements

Traffic volumes on roads in the vicinity of the proposed quarry have been taken from Main Roads traffic data. Current traffic 24 hour flows are:

;

G & G Corp 1/219 Midland Road HAZELMERE WA 6055


OCM042.1/04/15

tarsc


Karnup Road (E of Kwinana Fwy) 2,502 vehicles per day (Sept 2012) Hopeland Road (N of Lakes Rd) 645 vpd (May 2010) Lakes Road (W of McMahon Rd) 1,405 vpd (May 2010)

These flows occur typically between a 12 hour period from 7am to 7pm: Karnup Road (E of Kwinana Fwy) 2,086 or approximately 173 vph Hopeland Road (N of Lakes Rd) 559 or approximately 46 vph Lakes Road (W of McMahon Rd) 1,180 or approximately 98 vph

Of the daily traffic flows the proportion of heavy vehicles currently on these roads are:

Karnup Road (E of Kwinana Fwy) 12.9% Hopeland Road (N of Lakes Rd) 14.1% Lakes Road (W of McMahon Rd) 13.2%

The above information is shown in green on the attached figure. Expected Traffic Flows

The proposed development is expected to generate 20 semi-trailer sized movement to and from the quarry each day between 6am and 6pm Monday to Saturday and up to 5 small vehicular trips to the quarry around 6am and then from the quarry at around 5pm. Adding this expected traffic flow to the current flows, the following flows are expected: Expected Daily Traffic Flows

Karnup Road (E of Kwinana Fwy) 2,522 vpd Hopeland Road (N of Lakes Rd) 660 vpd Lakes Road (W of McMahon Rd) 1,410 vpd

12 hour period from 7am to 7pm: Karnup Road (E of Kwinana Fwy) 2,106 or approximately 175 vph Hopeland Road (N of Lakes Rd) 569 or approximately 47 vph Lakes Road (W of McMahon Rd) 1,185 or approximately 99 vph

Proportion of Heavy Vehicles: Karnup Road (E of Kwinana Fwy) 13.4% Hopeland Road (N of Lakes Rd) 16.1% Lakes Road (W of McMahon Rd) 13.3%


OCM042.1/04/15

tarsc


The above information is shown in red on the attached figure. Traffic impacts

In terms of traffic flow changes, the proposed quarry is expected to have a 1-3% increase in traffic flows on the three main access routes to and from it. As traffic flows can vary from 5% either side of an average traffic flow, this increase in traffic flow will be unnoticeable to the average motorist. The proportion of heavy vehicles will remain close to current levels for Karnup Road, Hopeland Road and Lakes Road. The expected traffic flows fall well below capacity limits for the roads and intersections with all impacts expected to be minimal. Road Safety

Sight distances were assessed for the proposed quarry entrance with the following measurements estimated:

From Quarry to north 250m From Quarry to south 275m

Australian Standards requires that a 153m sight distance be provided for a 5 second gap in traffic as an absolute minimum and a 244m sight distance for an 8 second gap as a desirable minimum. The current sight distances exceed these minimums and thus it is considered acceptable. In terms of recorded crashes, the current crash rates for Hopeland Road and its intersections with Karnup Road and Lakes Road were assessed with the results below: Hopeland Road This 17km section of road has had 9 crashes recorded over the 5 year period up to 31/12/2013. These crashes were typical of a rural road with 2 hit object, 1 hit animal with most occurring during daylight hours. There were no fatalities recorded. Over the length of road this works out to be a crash rate of 0.47 crashes per million vehicle kilometres (MVkm) on the road. This is less than the network average for similar road of 0.67 crashes per MVkm. Thus, Hopeland Road is concluded to be a safe road based on this measure. Intersection of Hopeland Rd/Karnup Rd This intersection has had 3 crashes recorded over the 5 year period up to 31/12/2013. These crashes were typical of a four-way intersection with all 3 crashes being right angle. There were no fatalities recorded. Based on the traffic


OCM042.1/04/15

tarsc


volumes entering the intersection this works out to be a crash rate of 0.61 crashes per million vehicles (MV) entering the intersection. This is slightly more than the network average for similar roads of 0.59 crashes per MV but less than the critical crash rate of 2.38 crashes per MV. It is noted that the Hopeland Road approach to Karnup Road has been modified in the past 12 months with the inclusion of a traffic island in Hopeland Road to reinforce the intersection priority, this may have addressed this crash rate. Thus, this intersection is concluded to be safe based on this measure. Intersection of Hopeland Rd/Lakes Rd This intersection has had 1 crash recorded over the 5 year period up to 31/12/2013. This crash wase typical of a four-way intersection with it being right angle. There were no fatalities recorded. Based on the traffic volumes entering the intersection this works out to be a crash rate of 0.28 crashes per million vehicles (MV) entering the intersection. This is less than the network average for similar roads of 0.59 crashes per MV. Thus, this intersection is concluded to be safe based on this measure. Critical Crash Rate

This is the crash rate above which crashes occur in excess of a significance level above the network average. The critical crash rates described above are at the upper 5% value, one tailed. Crashes which occur at a rate greater than the network average and less than the critical crash rate (based on either the MV or MVkm exposure level) are typically acceptable. If the crash rate is close to (from 0.9 times the critical crash rate) or exceeds the critical crash rate this suggests a possible safety issue requiring possible road safety countermeasures.

Road Geometry

The road geometries were assessed for the various routes and intersections proposed to be used by the vehicles travelling to and from the proposed quarry. Both the intersection of Hopeland Road with Karnup Road and Lakes Road were found to adequately cater for the expected semi-trailer sized vehicles. The intersection of Hopeland Rd/Karnup Rd with the traffic islands in Hopeland Road, has the traffic islands with fully mountable kerbs, so as to allow semi-trailer sized vehicles to turn at the intersection. The intersection of Hopeland Rd/Lakes Rd has no traffic islands and there is sufficient road space for a semi-trailer sized vehicle to turn at the intersection. Hopeland Road was found to have a 6.0 to 6.2m seal with 1.0m wide gravel shoulders either side of this. No separation of edge lines were painted and the


OCM042.1/04/15

tarsc


speed limit is 110km/h. This road is classified as a Regional Distributor under the function road hierarchy. Lakes Road is also classified as a Regional Distributor with a speed limit of 100km/h near Hopeland Road. This road has a 6.5m wide seal with 1.5m wide gravel shoulders either side. Separation and edge line marking is painted on the road. Lakes Road is part of the Restricted Access Vehicle route for heavy vehicles. This road can be used for vehicles up to Class 3, typically B-doubles and road trains. Karnup Road is classified as a Regional Distributor with a speed limit of 100km/h near Hopeland Road. This road has a 8m wide seal with 1.5m wide gravel shoulders either side. Separation and edge line marking is painted on the road. The slight increase in traffic flows from the proposed quarry operations will be able to be carried by the current geometries of these roads. The current crossover geometry will allow semi-trailer sized vehicles to enter and exit the property without need for any road modifications. The current radii of the turn-outs allow a semi-trailer sized vehicle to exit the property, turning left or right, onto the eastern side of Hopeland Road and then manoeuvre to become lane correct. The same holds true for the turn manoeuvre from Hopeland Road into the crossover. Vehicle approaching from the south will require to swing onto the southbound direction of Hopeland Road to allow a single movement turn into the crossover. Given the low volumes of traffic on Hopeland Road, this is considered acceptable. Conclusions

The proposed quarry is expected to generate a small amount of traffic up to 50 vehicle movements per day. This traffic flow, once distributed onto the road network, will be an insignificant increase compared to current traffic flows. The road geometries will be able to cater for the expected traffic flows with no modifications required.
