iii Alkimos Stockpile Site Development Application

iv Introduction

This report has been prepared by element, on behalf of the Public Transport Authority (PTA), in support of a temporary stockpile site at Lot 9602 on Deposited Plan 409771 that is directly associated with the construction of the Yanchep Rail Extension project (YREP) that is discussed in more detail below. The stockpile site is located within the suburb of Alkimos within the local government area of the City of Wanneroo. Background The PTA is developing the Yanchep Rail Extension project as part of the Western Australian Government’s METRONET vision and delivery. The project will extend the Joondalup railway line beyond the existing Butler Station and will introduce another 14.5km of railway, new stations at Alkimos, Eglinton and Yanchep, and associated infrastructure. The construction and access area associated with the railway and temporary stockpile site proposed by this application has been selected to coincide with proposed future urban development and/or roads either reserved by the Metropolitan Region Scheme (MRS) or detailed within approved and draft Local Structure Plans (LSPs) and therefore designated to be cleared of vegetation. A total of 7.3 km of narrow-gauge dual track railway will be constructed within the corridor as part of the first construction stage up to the proposed new station at Eglinton. The railway will be situated below ground level, constructed within a cutting that has a general depth of approximately five (5) metres below the surrounding ground level. At one location, the cutting passes through a large and high sand dune where the depth of the cutting will be at its deepest, approximately 20 metres from the surrounding ground level. Batters and/or retaining walls will be used to stabilise the slopes down to formation level. This application relates to a proposed stockpile location in Alkimos, that is required to accommodate the extracted material during the construction of the Yanchep Rail Extension project for a temporary period only. Planning Approvals Required The PTA are considered to be an ‘Agent of the Crown’ for the purposes of public works development. Section 3 of the Western Australian Planning Commission (WAPC) Planning Bulletin 94 (PB94) best summarises the way this relates to local planning schemes below - Section 6 of the Planning and Development Act 2005 (PD Act) states: “nothing in this Act interferes with the right of the Crown, or the Governor, or the Government of the state, or a local government - (a) to undertake, construct or provide any public work; and (b) to take land for the purposes of that public work.” In general terms, this section gives the bodies referred to in section 6, “section 6 bodies”, the power to undertake a public work or take land for the purposes of a public work without obtaining development approval from the responsible authority under the relevant planning scheme. This does not however exempt the PTA from any applicable Region Scheme approval, as per the following text: Public works under a region planning scheme Section 5(2) states that a region planning scheme binds the Crown (ie all section 6 bodies except local government). This means that the exemption provided by section 6 does not extend to the requirements of a region planning scheme. As such, section 6 bodies may be required to apply for approval to commence development, including public works, under a relevant region planning scheme.

1 Alkimos Stockpile Site Development Application

If a section 6 body is exempt from requirements of the local planning scheme, but is required to make an application to the WAPC for development approval under the region planning scheme, then the section 6 body must provide the WAPC with evidence that the section 6 body has consulted with the local government as required under section 6(2) and (3) of the PD Act. The PTA is therefore considered to be exempt from requiring development approval from the local government for these works, however, the proposal still requires approval from the WAPC as the Section 6 exemption does not apply to the MRS. Further, the proposed development will locate within an area that is subject of a declaration under Section 112 of the PD Act, which states: (1) If the Commission considers that any land may be required for one or more of the purposes specified in Schedule 6, the Commission may by notice published in the Gazette and with the approval of the Minister declare that land to be a planning control area. On 27th March 2019, the WAPC resolved to declare a planning control area (PCA) over the subject site being PCA 132. All development within a PLA requires approval by the WAPC as set out under Section 115 of the PD Act. Section 115 of the PD Act states: (1) A person who wishes to commence and carry out development in a planning control area may apply to the local government in the district of which the planning control area is situated for approval of that development. (2) An applicant is to submit to the local government such plans and other information as the local government may reasonably require. (3) The local government, within 30 days of receiving the application, is to forward the application, together with its recommendation, to the Commission for determination. The PTA therefore seek approval from the WAPC under the MRS for the proposed stockpile location at Alkimos that is associated with the YREP as part of the Western Australian Government’s METRONET public transport program.

2 Proposed Development

Development Description This application relates to the development of an area of land for the purpose of temporarily stockpiling excavated material as part of the Yanchep Rail Extension project within the suburb of Alkimos. The stockpile location has been carefully selected to occur within an area of land that contains existing degraded vegetation with low environmental significance. The stockpile site will have direct access to the construction corridor where possible to reduce overall haulage distance of the excavated material. Material will be stockpiled to an approximate height of four (4) metres and is anticipated to hold approximately 600,000m3 within a 20 hectare site. To support the daily operation of the stockpile activities on site, associated infrastructure will be located within the site and include portable site ofices, toilet facilities and fencing to contain and securely store equipment after operational hours. The stockpile site is anticipated to operate during normal construction hours only, defined as 7:00a.m. to 7:00p.m. on days other than Sunday’s and public holidays. If works are required to be undertaken outside of normal construction hours then approval would be sought from the responsible authority. Alkimos Stockpile and Dust Management Plan A Stockpile and Dust Management Plan (SDMP) has been prepared to support the proposed development and provides additional detail on the ongoing operation and management of the temporary stockpiling facility. The following summarises the key matters addressed in the SDMP, with further information available within the SDMP at Appendix C. Refer to Appendix C - Stockpile and Dust Management Plan. Communication Process The PTA have prepared a Communications and Stakeholder Engagement Strategy to inform ongoing liaison with the community. The objectives of the Strategy include: • Build relationships with key stakeholders and foster support for the project by involving stakeholders, where and as early as possible. In the delivery phase, the objective of engagement will be to manage and minimise construction impacts. • Communicate the project vision and benefits to allow for a greater understanding of the alignment, station locations and why the line is being extended. • Identify stakeholder and community perceptions of potential risks/impacts/issues associated with the project and use this information to inform project planning. • Establish opportunities for two-way feedback to maximise project outcomes through obtaining local knowledge and expertise. • Provide regular information when and how stakeholders wish to receive it. The PTA has continued to liaise with the local community and attend events to provide information on the YRE project. It is anticipated that stakeholders and the community will be engaged as part of the proposed development application process..

3 Alkimos Stockpile Site Development Application

Separation Distances The proposed stockpile site will be separated from existing development in the area, with the nearest sensitive receptor (residential development south of Howden Parade) being located approximately 600 metres away. The Environmental Protection Authority’s Guidance for the Assessment of Environmental Factors – Separation Distances between Industrial and Sensitive Land Uses No. 3 (Guidance Statement No. 3) provides for separation distances between industry and residential land uses, however, there are no recommended distances provided for bulk earthworks activities. Notwithstanding this, management activities addressed within the SDMP are considered to provide for an appropriate level of protection through dust management, noise management and the like. Dust Management Dust management measures are outlined within the SDMP, which includes the following dust preventative measures: 1. Access tracks/routes to be constructed of material that minimises dust generation as far as is practicable. 2. Watering and wetting down of access roads and tracks as required. 3. Stockpiles to be wetted down by water cart where possible. 4. Consideration will be given to utilising a hydromulch for stockpiles generating dust for longer term dust minimisation. 5. Consideration will be given to utilising a dust suppressant agent on access tracks where excessive dust generation becomes problematic. Stormwater Management All stormwater will be entirely contained within the site via onsite infiltration to ensure there is no uncontrolled discharge outside the site. Stormwater diversion channels or bunds will be constructed to divert surface water flows, minimise soil erosion and trap sediment within the site. Trafic Management Plant associated with stockpiling activities will have to enter the site via public roads initially. After this, all trucks and other plant associated with the stockpiling activities will subsequently be contained within the site and railways boundary. Access will take place through the rail construction corridor located to the west of the proposed stockpile site to limit the potential disturbance on the locality. Signage will clearly indicate the location of gate entrances to minimise incorrect routing of vehicles. Access tracks to and within the site will be constructed to a hard standard (compacted limestone) to limit dust creation and provide better access during wet conditions. Noise Management All works within the stockpile sites are planned to be undertaken during standard construction hours only, defined as 7.00 a.m. to 7.00 p.m. on days other than Sundays and public holidays. If works need to be undertaken outside of these hours, approvals will be sought from the City of Wanneroo and an out-of-hours noise management plan (NMP) will be developed and approval sought form the City of Wanneroo. Complaints will be recorded in the PTA complaints register and include location, date, time, nature of complaint, and complainant details.

4 Site Details

Site Location and Property Description The proposed development will be located within an area of land described as Lot 9062 on Plan 409771 (the subject site) and has an overall land area of 1,991,435m2. The proposed development will locate within a portion of the subject site only and will utilise approximately 20ha. Refer to Appendix A – Development Plans The subject site does not contain any existing development and is largely comprised of existing vegetation that is largely degraded and of low environmental significance. Refer to Figure 1 – Location Plan Refer to Figure 2 – Aerial Plan Refer to Figure 3 – Site Plan The following table provides a legal description of the subject lot. Lot No. Address Volume Folio Plan/Diagram Registered Proprietor 9602 No street address 2914 425 409771 WA Land Authority Refer to Appendix B - Certificate of Title Site Context and Surrounding Developments The subject site is located within the suburb of Alkimos, approximately 40km north of the Perth CBD and approximately 16k north of Joondalup. The subject site can be described as being located within an area that is continuing to undergo significant residential development associated with new housing estates. Despite the ongoing development being undertaken within the area, a significant amount of land remains undeveloped and typically consists of degraded vegetation. Approximately 600m immediately south of the proposed development lies an area of residential development that is subject to Agreed Structure Plan 60 (ASP60) - Lots 1001 & 1002 Marmion Avenue, Alkimos. The proposed development itself will locate within the Alkimos City Centre Structure Plan, which sets out a number of development controls that apply to development within the area. The future railway corridor is identified within Alkimos City Centre Structure Plan, although the stockpile location is not, likely due to the temporary nature of the site for this purpose.

8 Environmental and Heritage Considerations A desktop search indicates that the subject site: • Has no known European or Aboriginal heritage significance; • Does not pose a risk of encountering Acid Sulphate Soils; and • Is not a registered contaminated site. An assessment of the soil to be excavated as part of the project has previously been undertaken and this determined that most of the source soils to be clean fill in accordance with the revised Department of Water Environment Regulation (DWER) Landfill Waste Classification and Waste Definitions (as amended 2018). Further testing of soil may be required within one identified area and in this respect, the SDMP outlines the process that will be undertaken. Refer to Appendix C – Stockpile and Dust Management Plan The Department of Fire and Emergency Services (DFES) Map of Bush Fire Prone Areas identifies the subject site as falling within a bush fire prone area as designated by the Fire and Emergency Services (FES) Commissioner. A Bushfire Risk Management Plan has been undertaken for the Yanchep Rail Extension part 2 project. This sets out a number of bushfire mitigation measures that will also inform the ongoing operation of the stockpile activities and includes: • Fire danger rating controls; • Harvest and vehicle movement ban controls; • Bushfire warning controls • Evacuation plan and assembly points; and • Bushfire suppression. Further information can be found within the SDMP at Appendix C. Refer to Appendix C – Stockpile and Dust Management Plan. Further to the ongoing mitigation meansures outlined above and included within the SDMP, Strategen have prepared a Bushfire Management Plan (BMP) that has assessed the bushfire risk and potential impact to the proposed infrastructure. The BMP provides advice and recommendations regarding appropriate bushfire management responses in consideration of both mandatory and non-mandatory measures. The BMP outlines that the location of the site compound is recommended to locate within the cleared areas to provide suficient separation distances to achieve a BAL rating less than BAL-29. Refer to Appendix D - Bushfire Management Plan It is anticipated that a condition of approval will require the proposed development to comply with the recommendations of the BMP.

10 Planning Framework and Assessment

Metropolitan Region Scheme The subject site is located within Planning Control Area No. 132 under the Metropolitan Region Scheme (MRS). The declaration of Planning Control Area No. 132 will allow for the ongoing development of the Alkimos Railway Station and immediate surrounds. The WAPC consider that the Planning Control Area is required to ensure that no development occurs on this land which might prejudice this purpose until it may be appropriately reserved under the MRS. The proposed development is directly associated with the delivery of the State Governments METRONET vision and is required as part of the rail corridor construction. The proposed development is entirely consistent with the planning control area recently declared over the area. Refer to Figure 4 – Extract of Metropolitan Region Scheme City of Wanneroo Town Planning Scheme No. 2 As noted above, the PTA are considered to be an ‘Agent of the Crown’ for the purposes of public works and do not require planning approval from the City. Notwithstanding, The City’s Town Planning Scheme No. 2 (TPS2) identifies land use permissibility within designated zones. The proposed development is considered to fall most closely within the definition of a ‘Public Utility’, which is defined as follows: Any work or undertaking constructed or maintained by a public authority or municipality as may be required to provide water, sewerage, electricity, gas, drainage, communications, passenger transport or other similar services. Given the nature of the proposed development, the above land use definition most accurately describes the proposed development sought as part of this application. The subject site is zoned ‘Centre’ under the City’s TPS2 and is located within the Alkimos Eglinton Development Contribution Area (DCA1). Refer to Figure 5 – Extract of City of Wanneroo Town Planning Scheme No. 2 DCA1 is outlined as generally conforming to the Alkimos Eglinton District Structure Plan, the Northern Coastal Growth Corridor Community Facilities Plan and the City of Wanneroo Long Term Financial Plan 2013/14 - 2022/23. Developer contributions are not applicable in this instance as the proposed development is exempt from the need to require planning approval under the City’s TPS2. Notwithstanding this, the City will be a key referral agency for the determination of the application under the MRS by the WAPC and as such will be assessed with regard to the relevant general objectives of its local planning scheme. The following objectives of the City’s TPS2 are considered most relevant to this application: (d) To facilitate the co-ordination and early provision of social and community facilities and other physical infrastructure in line with the needs of new development. (k) To ensure that adequate regard is given to the protection of the natural environment in the determination of land use and development proposals in accordance with sustainable development principles. (o) To ensure that proper regard is given to the needs of the community in the determination of land use and development proposals.

It is considered that the proposed development accords with the abovementioned aims and objectives in that it will ensure the ongoing delivery of essential community service infrastructure that will benefit the local community in addition to the wider population of Perth. The location of the proposed development has been specifically selected to occur within an area of land with degraded vegetation, limiting any further need for potential clearing. A Stockpile Management Plan has been prepared and is to be addressed as part of the ongoing operation of the subject site as a stockpile location. City of Wanneroo Local Planning Policy 4.18 - Earthworks and Sand Drift The proposed development site was considered against the City’s Local Planning Policy 4.18 - Earthworks and Sand Drift. Utilising the Site Classification Assessment Chart, the proposed development site produced a total score of 238, which means that the site is a Classification 2, being of low risk. Dust management measures will be employed throughout the operation of the facility and appropriate complaints management systems will be undertaken to ensure the stockpile site operates to an appropriate standard and limit any potential nuisance on the surrounding locality.

14 Conclusion

This report has been prepared by element and on behalf of the PTA, to support the proposed development of a stockpile location that is directly related to the Yanchep Rail Extension project being undertaken, which will deliver an additional 14.5km of railway, new stations at Alkimos, Eglinton and Yanchep, and associated infrastructure. This application seeks the necessary development approval from the WAPC under the MRS for the proposed development as shown in the development plans, which is to take place within a declared planning control area (PLA132). This report sets out the development approval framework, project area description, proposed development, and planning framework applicable to the proposal. A planning assessment is also provided although the relevance of normally applicable development standards and requirements is limited due to the nature of the proposal. Notwithstanding the exemptions that the PTA enjoys from local authority approval as a public authority, the proposal is demonstrated as being consistent with the purposes, objectives and intent of the applicable local planning scheme and in accordance with the principles of orderly and proper planning on the basis that it will have a limited impact on the local amenity and is to be appropriately managed throughout its operational duration. In order to ensure the timely delivery of this important infrastructure project it is respectfully requested that the development approval is issued within the applicable statutory timeframe to meet the associated timeframes with the delivery of the project.

1 Introduction

The Public Transport Authority of Western Australia (PTA) is developing the Yanchep Rail Extension (YRE) project as part of the Western Australian Government’s METRONET vision. This is an extension to the Joondalup railway line in Perth’s northern suburbs, 26 km north of the Perth CBD. The YRE project includes 14.5 km of railway beyond the existing Butler Station, new stations at Alkimos, Eglinton and Yanchep, and associated infrastructure.

The proposal will extend the north metropolitan railway between the existing Butler Station and the proposed Eglinton Station. The development envelope is 70.2 ha in size, and is comprised of two components: a 45.4 ha development footprint and a 24.8 ha construction and access area (Figure 1). The development footprint includes a contingency for a turnback facility (to allow for the turning of two six car trains) to be constructed to the north of the Eglinton Station in the event that Part 2 of the YRE project does not proceed. The construction and access area has been selected to coincide with proposed future urban development or roads either reserved by the Metropolitan Region Scheme (MRS) or as detailed within approved and draft Local Structure Plans (LSPs) and therefore designated to be cleared.

A total of 7.3 km of narrow-gauge dual track will be constructed within the railway corridor. The railway is below ground level and will be constructed in a cutting. Generally, the depth of cutting is approximately 5 m below the surrounding ground level. The railway and ancillary infrastructure is contained within the railway corridor with either batters and/or retaining walls used to stabilise the slopes down to formation level. Where the cutting passes through a large and high sand dune, the depth of the cutting is at its deepest, approximately 20 m from the surrounding ground level. Two new train stations are proposed; Alkimos (approximately 5.3 ha in the development footprint) and Eglinton (approximately 6.9 ha in development footprint). Intermodal rail, bus, ‘park and ride’, ‘kiss and ride’ and active mode (cycling and walking) facilities will be constructed at each station.

This document addresses management of excavated soil stockpiles during construction of Yanchep Rail Extension Part 1, Butler to Eglington section at the stockpile site located south east of the proposed Alkimos Station (figure 1). The document has been prepared in consideration of the City of Wanneroo Local Planning Policy 4.18: Earthworks and Sand Drift 2016. This document also addresses ongoing management of the stockpile if the stockpile is still present at Day1 operation of Alkimos Train Station.

Figure 1: Location of proposed stockpile site

2 Stockpile Sites Location

An area with degraded vegetation condition has been chosen as the location for the stockpile site (figure 1). The stockpile location has been also been selected to minimise haulage distances and have direct access to the construction corridor, where feasible.

The stockpiles will be at a height of approximately four meters. The total volume of the stockpiles will be approximately 480, 000 M3 (LCM).

3 Communication Process

In line with the objectives of the Yanchep Rail Extension, Delivery Stage: Communications and Stakeholder Engagement Strategy PTA met with the City of Wanneroo representatives on 18 March 2019 to discuss the scope of the works required for the development and operation of the stockpile sites. PTA outlined the process and elements required for the establishment of the stockpile sites. The City of Wanneroo advised the PTA that a Development Application (DA) is required for the proposed stockpile and a stockpile management plan is required to be included with the DA.

The objectives of the PTA Communications and Stakeholder Engagement Strategy include:

• Build relationships with key stakeholders and foster support for the project by involving stakeholders, where and as early as possible. In the delivery phase, the objective of engagement will be to manage and minimise construction impacts. • Communicate the project vision and benefits to allow for a greater understanding of the alignment, station locations and why the line is being extended. • Identify stakeholder and community perceptions of potential risks/impacts/issues associated with the project and use this information to inform project planning. • Establish opportunities for two-way feedback to maximise project outcomes through obtaining local knowledge and expertise. • Provide regular information when and how stakeholders wish to receive it.

Information on the YRE project including the bulk earthworks and stockpiles will be included in the Alkimos Vista website.

PTA has also participated in the Alkimos Vista display village opening on 6 April 2019. PTA was present to provide information and feedback to the community on the YRE project.

PTA also attended Retro Rewind on 9 March 2019, an event held in Yanchep National Park by the City of Wanneroo. PTA provided information and feedback to community on the YRE project.

4 Separation distance from sensitive receptors

The EPA’s Guidance for the Assessment of Environmental Factors – Separation Distances between Industrial and Sensitive Land Uses No. 3 (Guidance Statement No. 3) provides for separation distances between industry (such as extractive industries) and sensitive land uses, such as residential developments, hospitals, motels, hostels, caravan parks, school, nursing homes, child care facilities, shopping centres, playgrounds, and some public buildings. Some commercial, institutional and industrial land uses which required high levels of amenity or are sensitive to particular emissions may also be considered ‘sensitive land uses’. Examples include some retails outlets, offices and training centres, and some types of storage and manufacturing facilities.

Under Appendix 1 of the Guidance Statement No. 3, there is no recommended separation distance for bulk earthworks. The nearest sensitive receptors which are residents located South of Howden Parade are some distance away from the proposed stockpile area. The residences are located approximately 600m from the proposed stockpile site (figure 2). In addition there is a grove of vegetation to the South of the proposed stockpile site that will act as a buffer between the stockpile site and houses in Howden Parade.

5 Acid Sulfate Soil

The DWER’s ASS risk mapping does not identify ASS within or adjacent to the development envelope (Eco Logical 2018). Golder Associates carried out a Preliminary Site Investigation in 2017 and did not identify ASS (Golder 2017). ASS is therefore not considered further in this report.

No recorded contaminated sites (DWER’s Contaminated Sites Database) occur within the vicinity of the proposed stockpile site.

If any ASS is encountered then it will be managed in accordance with the testing process outlined in section 5.

Figure 2: Distance to nearest sensitive receptors from the proposed stockpile site

6 Soil condition and classification

Golder carried out a waste classification and waste definitions assessment in 2018 of the soil that will be stockpiled in the proposed site (Golder 2018). The assessment identified most of the source soils to be clean fill in accordance with the revised Department of Water Environment Regulation (DWER) Landfill Waste Classification and Waste Definitions (as amended 2018). Therefore no further testing of source soils is required. There is one area that the Golder assessment identified as potentially having uncontaminated fill. This area is East of Shorehaven Boulevard and was inferred to potentially have had intensive agriculture/ horticulture practice in the past. The soil from this area will be segregated and tested. If the tested soil is found to meet the classification requirements for uncontaminated fill it will be treated as clean fill.

If the tested soil is found to be contaminated then the following be carried out:

a. Extracted soil will be segregated and stockpiled to comply with Contaminated Sites Act 2003, Contaminated Sites Regulations 2006, and to aid potential material re-use or disposal applications, this will also minimise and eliminate where possible the need for subsequent sorting and segregation of stockpiled soil. b. A sampling register will be maintained describing sampling procedures, which include consistent sample labelling nomenclature to accurately identify sample source locations, sample type, sample date, visual observations and planned stockpile location for similar adjacent excavated material. c. Sample location will be recorded at the time of samples taken and sample location will be photographed. d. Frequency of logging, testing and characterisation of materials will occur to ensure adequate material type classification as spoil production progresses will be recorded. e. Records of all logs, testing and material types, characterisation and classification, by material type will be kept. f. An inventory of all stockpiled materials’ locations and volumes measured in bank cubic meters (BCM) representing the volume of undisturbed ground pre-excavation, recorded per material type will be maintained. g. A Stockpile Materials Tracking Register will be maintained to record the quantity and type of material entering and exiting the stockpile site.

Any previously unidentified contaminated soil or unexpected finds encountered will be managed in accordance with the testing process outlined above. Monthly surveys of stockpiles that have had soil added the preceding month will be carried out.

7 Dust Management

Dust will be managed in accordance with the approved Yanchep Rail Extension: Part 1 – Butler to Eglinton Construction Environmental Management Plan measures. These dust management measures include:

1. Access tracks/routes to be constructed of material that minimises dust generation as far as is practicable. 2. Watering and wetting down of access roads and tracks as required. 3. Stockpiles to be wetted down by water cart where possible. 4. Consideration will be given to utilising a hydromulch for stockpiles generating dust for longer term dust minimisation. 5. Consideration will be given to utilising a dust suppressant agent on access tracks where excessive dust generation becomes problematic. 6. Consideration will be given to ceasing works in dry and windy conditions

The proposed site was assessed under the City of Wanneroo, Local Planning Policy 4.18: Earthworks and Sand Drift 2016, Site Classification Assessment Chart (Appendix 1). The result of this assessment produced a total score of 238. Based on this score Site Classification 2 will apply. A site assessed as Site classification 2 under the Site Classification Assessment Chart is considered low risk and the dust management measures outlined above and the contingency actions below adequately mange the potential low risk. The main factor influencing this relatively low score was the distance of the stockpile away from sensitive receptors.

Dust will be visually monitored on an ongoing basis. If the project encounters complaints and issues with dust generation and the dust mitigation measures do not resolve dust issues, consideration will be given to monitoring dust on a periodic basis. Complaints process will also be followed as outlined in section 14. Contingency measures may include:

1. Application of hydromulch 2. Use of dust suppressant on access tracks and key areas of vehicle movement 3. Installation of wind fencing 4. Consider installation of onsite dust monitors

7.1 Medium Term Dust Management It is understood that the stockpile will be removed prior to Day 1; however if there is a remnant stockpile PTA and its nominated contractor will implement the following contingency actions until the stockpile has been removed. The proposed stockpile will be stabilised until such time the stockpile is decommissioned and stockpile site handed over to LandCorp. The stockpile will be stabilised upon completion by covering with hydromulch and watered as necessary to achieve germination. A quarterly inspection program will be carried out and involve a drive around the stockpile, visual inspection and photographic documentation of the state of the stockpile.

8 Stormwater Management

Drainage will be designed for storm water to drain within the site and not leave the site. Storm water will be managed within the site via onsite infiltration to ensure there is no uncontrolled discharge from the site.

The following measures will be implemented:

1. Stormwater diversion or bund will be constructed where required to divert surface water away from stockpiles, and to minimise soil erosion caused by concentrated flows, 2. Erosion control measures will be implemented to minimise soil erosion caused by storm water, 3. Sediment control measures will be implemented to trap and retain sediment within the site.

9 Traffic Management

Trucks and other plant will not enter the stockpile site via public roads. Access will be through the rail construction corridor west of the proposed stockpile site (figure 2).

Signage will be erected to clearly communicate gate entrance to minimise incorrect routing of vehicles. The site access tracks will be hard standed (compacted limestone) to minimise dust, provide better access during wet conditions, and reduce trafficking of mud on tyres. A radio channel will be allocated for all site traffic, with signage in place to advise of the correct channel. Barricading will be used to delineate stockpile areas and access tracks. This will consist of bunting and physical barricading.

Predicated vehicle/plants required for the stockpiling works and the frequency of movement is provided in table 1.

Table 1: Vehicle/Plant Movement

Type and number of vehicle/ plant Estimated vehicle movement frequency 4 Caterpillar 657 Scrapers Enter and circulates the area 6-8 times per hour each 4 Caterpillar 745 40 Tonne Dump trucks Enter and circulates the area 6-8 times per hour each 2 50kl Water Cart Circulates the area twice per hour each 2 Caterpillar 980 front end loaders Permanently at stockpiles pushing up, segregating, and maintaining haul tracks 2 Light vehicles Moving between cut/ excavation site and stockpile area as required. Note access will be through the rail construction access.

Traffic management for removing the soil from the stockpile site to the final destination will be developed once the final destination has been determined. This will be done in consultation with the City of Wanneroo to meet the traffic management standards of the City.

10 Noise Management

There will be no exceedance of works noise limits and the works will be undertaken in accordance with Environmental Protection (Noise) Regulations 1997. All works will be planned to be undertaken during standard construction hours only, defined as 7.00 a.m. to 7.00 p.m. on days other than Sundays and public holidays.

If works are required to be undertaken outside standard construction hours then appropriate approvals will be sought from the City of Wanneroo. In addition an out-of-hours noise management plan (NMP) will be developed and be approved by the City of Wanneroo. The NMP will identify reasons for the construction work, the type and duration of work to be undertaken, predicted noise emissions, noise management measures to be implemented during the out of hours work, and noise monitoring. Complaints will be recorded in the PTA complaints register including location, date, time, nature of complaint, and complainant details. Complaints will be managed in accordance with the PTA complaints process as outlined in section 14.

11 Unexploded Ordnance

It is unlikely that unexploded ordnance (UXO) will be present in the proposed stockpile area (Milsearch 2018). However if an item suspected of being UXO or a component thereof is found then the following will be followed:

1. If a suspicious Item is found, DO NOT TOUCH IT. This includes making any attempt to move the item to a “safe” location; 2. Take action, where appropriate, to prevent it being disturbed by others; 3. Mark its location so that it can be found later. Coloured tape or paint make an easily recognized marker material; 4. Note its approximate dimensions and general appearance; 5. Note the route to its location; and 6. Where applicable, inform the site manager/ contact, property owner, contractor, City of Wanneroo, Department of Biodiversity, Conservation, and Attractions of the find; 7. Advise the Police as soon as possible. They will instigate a request for Defence personnel to attend and dispose of the item.

12 Bushfire Management

The PTA has developed a Bushfire Management Strategy which provides the bushfire management framework that outline bushfire risk reduction strategies across all PTA owned, managed, or leased land (PTA 2018). In addition the PTA has developed a Bushfire Risk Management Plan to identify and treat bushfire risks during construction of the YRE Project (ELA 2019).

Bushfire mitigation measures included in the Bushfire Risk Management Plan are below:

12.1 Fire Danger Rating controls

The following controls are to be implemented by PTA under all fire danger ratings (FDRs) (i.e. at all times): • Ensure all vehicles are: o fitted with fire extinguishers; and o regularly checked and cleaned to ensure no grass and vegetation build up; • Construct a minimum 6 m wide hardstand access track along the entire YRE project footprint prior to any other construction activities occurring to allow for an exit to the north and/or south in the event of a bushfire: o Ensure the access track is gated and locked at both ends on non-work days to prevent unauthorised access; o Consider implementing turning areas for 3.4 fire appliances (i.e. fire trucks) along the access track – consult with Department of Fire and Emergency Services (DFES)/ local brigade to identify appropriate locations; • Ensure all personnel visiting or working on the Project are aware of onsite and off-site muster points prior to commencement of construction; • Ensure that the location of all on-site and off-site muster points have considered bushfire risk and provide for access in two directions; • Ensure that sufficient vehicles are present at all times to safely evacuate all personnel working in the project footprint; and • Update all contractors, staff and visitors on FDR-specific controls for the day as detailed below.

12.2 Harvest and Vehicle Movement Ban controls

All controls specified in Section 12.1 are to be implemented during Harvest and Vehicle Movement Bans. In addition, the following will also apply: • No clearing of vegetation permitted; and • Use or operation of any engine, vehicle, plant, equipment or machinery in the area likely to cause a bushfire or contribute to the spread of a bushfire is not permitted.

12.3 Bushfire Warning controls

The following controls are applicable to the Project in addition to the Bushfire Warning instructions issued through text messages from DFES:

• Advice: Ensure regular communication is established between the Project fire warden and all staff, contractors and visitors within the project footprint to confirm personnel locations and consider evacuation strategies; • Watch and Act: Project fire warden to contact DFES immediately to determine appropriate course of action and inform all staff, contractors and visitors within the project footprint; • Emergency Warning: Project fire warden to coordinate evacuation to

appropriate muster point on advice from DFES; and • All Clear: Remain vigilant and ensure regular communication is established between the Project fire warden and all staff, contractors and visitors within the project footprint to confirm personnel locations and consider evacuation strategies in the event of a change in warning.

12.4 Evacuation plan and assembly points

The installation of a minimum 6 m wide hardstand access track along the entire YRE project footprint will allow for an exit to the north and/or south in the event of a bushfire. Evacuation direction is to be determined on direction from DFES or other emergency services and is to be coordinated by a PTA appointed fire warden for the project.

On-site and off-site emergency assembly (muster) points will be designated prior to construction and all contractors, staff and visitors will be made aware of their location prior to entry into the project footprint.

12.5 Bushfire suppression

The Yanchep Fire & Rescue Service (Volunteer fire brigade) is located approximately 15 Km from the proposed stockpile site and the Butler fire Brigade is approximately 5 Km from the proposed stockpile site. These stations are expected to provide a best-case emergency suppression response time of 30 minutes in the event of an emergency.

In the case of a fire ignition within or immediately adjacent to the project footprint and site resources cannot extinguish the fire, 000 will be called and a report will be made of the fire followed by an immediate evacuation in the direction / to a point advised by DFES and/or a PTA appointed fire warden for the project.

13 Spill Management

Rapid spill response will occur with any material spills to site in accordance with the PTA Spill Response Procedure. The spills will be immediately reported to the site supervisor. The site supervisor will coordinate the spill clean up. Material spilt during operation will be cleaned up immediately. Spill kits will be available on the site. All spills and spill related incidents will be documented and register of the incidents will be maintained.

In the event of a spill the following steps will be undertaken in accordance with the PTA Spill Response Procedure: Spill response • Isolate the area and prevent sources of ignition from entering; • Determine what substance has been spilt, where possible; and • Consider any health and safety issues (refer to the Material Safety Data Sheet for the substance).

If safe to do so: • Take steps to isolate the source of the Spill, where possible wearing the appropriate personal protective equipment (PPE); • Protect nearby drains and areas of unpaved ground from liquid ingress Spills, using

appropriate Spill kit equipment (drain seals, absorbent booms, etc); • Cover the area of the Spill in absorbent material; • Notify the Site Supervisor/Manager; • Once the majority of the Spill has been absorbed, place used absorbent material into waste bags contained in the Spill kit; and • The used absorbent material shall be stored as if it were a used chemical and disposed of as a Hazardous substances or Dangerous goods.

If not safe to do so or you do not know the nature of the spilt substance: • Contact your area Site Supervisor/Manager; • The Site Supervisor/Manager is to assess the risks associated with the Spill; • If the Site Supervisor/Manager considers the Spill safe to clean up, they shall instigate the Spills/leak response process; and • If the Site Supervisor/Manager does not consider the Spill safe to clean up, but that it does not constitute an environmental emergency, he/she shall alert any nearby staff and keep them well away and contact the PTA representative. The Site Supervisor/Manager shall arrange for a licenced contractor to attend site and clean up the spill.

14 Complaints Process

Complaints will be recorded in the PTA complaints register including location, date, time, nature of complaint, and complainant details.

All registered complaints will be investigated and complainants contacted within seven days of complaint. The outcomes of the investigation will be recorded in the complaints register. Implementation of contingency actions will be considered when complaints are received, and will be fed back to the complainant. A Compliance Assessment Report will identify the number of complaints per year and a summary of the outcome of the investigation and resolution of any complaints, including the management measures implemented.

Complaints can be made direct to the Metronet info line on 9326 3666 or email can be sent to [email protected]. The opening hours for the call centre are:

• Monday – Thursday: 5am – 12:30am • Friday/Saturday: 5am – 2am • Sunday/Public holidays: 5am – Midnight

In the event of afterhours work, all calls will be diverted to the Site Supervisor. Project signboards with Metronet branding and contact details will be installed and maintained at publicly accessible and visible locations adjacent to the stockpile, as consistent across all Metronet rail construction sites.

15 Site Handover

The site and stockpile will be managed by the PTA through their nominated contractor until decommissioning and handover of the Site to LandCorp at the end of duration as referred to in the Stockpile Lease between PTA and LandCorp. The following will be completed prior to handing over of the site to the landowner:

1. On decommissioning of the stockpile facility, the site will be tidied up, stabilised and, made secure, to meet the requirements of the subsequent land use. 2. The existing ground will be levelled and stabilised to meet the requirements of the subsequent land use. 3. Monitoring and maintenance of the site will be undertaken until handover. 4. The plant and equipment likely to be used to undertake the decommissioning works include: • 4 Caterpillar 657 Scrapers • 4 Caterpillar 745 40 Tonne Dump trucks • 2 50kl Water Cart • 2 Caterpillar 980 front end loaders

16 Monitoring and Review

A monitoring and review process will be undertaken during the construction of the Yanchep Rail Extension, until the return of the site to LandCorp. The process will ensure the management strategies and actions outlined above in the Stockpile and Dust Management Plan are met.

In addition audits of work practices will be carried out to ensure there is no adverse impact in relation to spoil production, stockpile management, and onsite reuse activities.

Table 2: Summary of monitoring that will be undertaken during construction and management of the stockpile facility
