EXECUTIVE SUMMARY

In October 2009 the State Government endorsed the commencement of investigations to create a Strategic Industrial Area at Ashburton North, which is 11km south-west of Onslow, to cater for proposed Liquefied Natural Gas (LNG) and domestic gas processing as well as related downstream processing opportunities. The ANSIA will promote regional development, provide a gas hub to monetise gas fields in the Carnarvon Basin and promote more diverse sources of domestic gas.

Following the adoption of numerous amendments to the Shire of Ashburton Town Planning Scheme No. 7 (TPS7) as well as a structure plan for the entire Ashburton North Strategic Industrial Area (ANSIA), a clear and coordinated vision for the ANSIA has been established, with which the Development Plan is consistent.

The ANSIA Structure Plan divides the project area into several stages due to the timeframe requirements associated with development of the various project components, with this Development Plan having been prepared for the portions of the ANSIA referred to as Stages 1B and 1C.

Stage 1B comprises the development of the Scarborough LNG and the Macedon Domestic Gas Projects, portions of land associated with the future industrial area (FIA) and a second Transient Workforce Accommodation (TWA) precinct.

Stage 1C comprises a General Industrial Area (GIA) north of the TWA precincts, and is intended to be developed to provide support services to the ANSIA, offshore facilities and the town of Onslow.

The Development Plan has been prepared in accordance with the statutory requirements outlined in TPS7 and subsequent Scheme Amendments as well as the strategic vision of the recently adopted ANSIA Structure Plan.

The Development Plan ensures that future stages of the development can easily be integrated into the development and developed in an orderly and proper manner in accordance with the ANSIA Structure Plan.

The site allocated to the Scarborough LNG project is provided for indicative purposes only and does not form part of this Development Plan. Once detailed planning for the Scarborough project is completed, an amendment to TPS7 and this Development Plan will be required.

The proposed Scarborough LNG site would be the only other defined LNG site in the ANSIA (apart from Wheatstone). To ensure a consistent approach to the rezoning of LNG sites at the ANSIA, proponents of the development would need to address environmental, access and infrastructure arrangements within the ANSIA. Proponents would also need to address social and infrastructure implications such development would have on the community of Onslow.

1.1 PREAMBLE

In October 2009 the State Government endorsed the commencement of investigations to create a Strategic Industrial Area at Ashburton North to cater for proposed Liquefied Natural Gas (LNG) and domestic gas processing as well as related downstream processing opportunities. The ANSIA will promote regional development, provide a gas hub to monetise gas fields in the Carnarvon Basin, and promote more diverse sources of domestic gas.

The State, through the Department of State Development (DSD), allocated land to three foundation proponents within the ANSIA to undertake investigatory works associated with the development of the following projects:

• Wheatstone LNG Project (413 Hectares) – Chevron;

3

• Scarborough LNG Project (344 Hectares) – ExxonMobil and BHP Billiton Petroleum (BHPBP) Joint Venture; and

• Macedon Domestic Gas Project (218 Hectares) – BHPBP.

In February 2010, the Shire of Ashburton (the ‘Shire’) took the final step in formalising the location of the ANSIA by initiating a scheme amendment (Amendment No. 9) to TPS7 to classify the designated area as a ‘Special Control Area’ and thereby establishing clear criteria required to progress more detailed zoning and development proposals. A major requirement identified under the amendment is for a structure plan to be prepared and adopted by the Shire and the Western Australian Planning Commission (WAPC) to guide the integration of all development in the ANSIA.

In 2010, a Structure Plan prepared for the whole of the ANSIA project was formally lodged with the Shire. The Structure Plan (referred to as the ANSIA Structure Plan) ensures development within the ANSIA is consistent with a clear and coordinated strategy. Following several amendments to the Structure Plan, Council at its Ordinary Meeting of 15 June 2011, resolved to adopt the Structure Plan for the purpose of advertising.

The ANSIA Structure Plan divides the project area into several stages due to the timeframe requirements associated with development of the various project components. Stage 1 consists of the land subject of known development interests as required by the foundation proponents as well as the development of a Future Industry Area (FIA)

incorporating downstream gas processing industries and other uses. Land with no current development intention in the short to medium term, and therefore set aside for future strategic industrial expansion, is referred to as Stage 2. (RefeR to figuRe 1)

Stage 1 is further demarcated into sub-stages primarily due to the advanced planning for Chevron’s Wheatstone project. Stage 1A comprises the Wheatstone project, a port and Common User Coastal Area (CUCA), (which will be managed by the Dampier Port Authority), and a Multi User Access and Infrastructure Corridor (MUAIC) for the purpose of shared transport and infrastructure.

Stage 1B comprises the development of the Macedon Domestic Gas Project, portions of land associated with the FIA and a second Transient Workforce Accommodation (TWA) precinct. Stage 1B also includes a truncation at the corner of the eastern MUAIC to allow for safe and efficient access along the MUAIC. Stage 1B also provides for the potential development of the Scarborough LNG plant, however this would be subject to a separate Scheme Amendment.

Stage 1C comprises the balance of Stage 1 identified for General Industry development for which further detailed planning can be expected in the future. This Development Plan has been prepared for the portion of the ANSIA referred to as Stages 1B and 1C.

Land with no current development intention in the short to medium term has been set aside for future strategic industrial expansion and is referred to as Stage 2.

This Development Plan has been prepared for the Stage 1B and 1C areas and addresses the relevant requirements of Appendix 7 detailed above.

2.1.2 Appendix 11

Appendix 11 of TPS7 outlines the requirements for planning of the ANSIA. Specifically, Appendix 11 comprises a ‘Policy Statement’ and a set of ‘Planning Requirements’ required to be addressed as part of structure planning and rezoning of the area.

Provision 1 under the ‘Planning Requirements’ states that “An ANSIA Structure Plan shall be prepared prior to or in association with the rezoning of land, within the ANSIA, to ‘Strategic Industry’ or other zone or reservation identified within the Structure Plan”.

The ANSIA Structure Plan was formally lodged with the Shire in 2010. The Structure Plan ensures development within the ANSIA is consistent with a clear and coordinated strategy. Following several amendments to the Structure Plan, Council at its Ordinary Meeting of the 5 October 2011, resolved to adopt the Structure Plan. The Structure Plan was subsequently endorsed by the WAPC on 31 October 2011.

Provision 9 of Appendix 11 states “When considering a request to initiate rezoning of land within the ANSIA to ‘Strategic Industry’ or other zone or reservation identified within the ANSIA Structure Plan, the local government shall only initiate an Amendment when it is satisfied that the proponent has prepared a structure plan dealing with the following matters:

a. The area to which the Amendment applies;

b. The need to extend outside the area of the ANSIA;

c. Key opportunities and constraints of the site including landform, topography, hydrology, landscape, vegetation, soils, conservation and heritage values, ownership, land use, roads and services;

2.2 ANSIA STRUCTURE PLAN

The ANSIA Structure Plan provides an integrated planning framework to ensure that development and land use by the various stakeholders is properly integrated in order to fulfill the project objectives in the most effective and sustainable manner. The Structure Plan also ensures an equitable approach to the provision of community services and infrastructure made necessary by development, within both the ANSIA and Onslow Township.

Preparation of the Structure Plan has been guided by a Working Group comprising:

• Chevron;

• Shire of Ashburton;

• Department of Planning;

• Environmental Protection Authority;

• Department of State Development;

• LandCorp;

• Dampier Port Authority; and

• Consultants to Chevron.

Specific technical input has been sought from:

• Department of Conservation and Environment;

• Main Roads Western Australia;

• Department of Transport;

• Water Corporation;

• Horizon Power; and

• Department of Water.

The Structure Plan identifies a number of discrete planning precincts that are generally distinguished by different land use functions, as follows:

• Port/Common User Coastal Area (Port/CUCA): this area comes under the jurisdiction of the Dampier Port Authority (DPA). The DPA will prepare a Port of Onslow Development Plan, and a Port of Ashburton Infrastructure and Land Use Master Plan to guide development within this area.

• Hydrocarbon Industry: consisting of dedicated proponent site sand some unallocated land areas.

• Future Industry: a proposed multi-user estate for other industrial uses for the downstream processing of domestic gas and/or industries offering synergistic services and/or facilities to existing and potential operations within the region.

• Transient Workforce Accommodation: two transient workforce accommodation sites for construction workers are provided for the hydrocarbon industry and general industry.

• General Industry: multi-user estates for general industrial uses that support the key industries of the ANSIA.

• Multi-User Access and Infrastructure Corridor(s): including transport corridors, domestic gas pipeline(s) and services.

• Unallocated Land: additional land set aside for future potential industrial expansion (Stage 2) if and when the demand arises.

12

The Structure Plan also classifies the precincts through reference to Local Scheme Zones and Reservations. The land subject of the Structure Plan falls within the ‘Strategic Industry’ zone (‘Hydrocarbon Industry’ and ‘Future Industry’ precincts), and the ‘Special Use – STWA’ zone (‘Transient Workforce Accommodation’ precinct) (RefeR to figuRe 4).

Condition 2 of the Structure Plan states that “Prior to the commencement of any use, subdivision or development the proponent shall prepare an amendment to the TPS7 and request the local government to initiate the amendment pursuant to the Planning and Development Act 2005. Such TPS7 Amendments shall reflect the ANSIA Structure Plan demonstrating to the satisfaction of the EPA/DEC, conformance to the Risk, Noise and Air Quality Buffer, as defined in ANSIA Structure Plan report (Figure 12) and/or to the minimum requirement for the described sensitive land use, for risk and noise as prescribed in the following documents:

1. Risk – Guidance Statement No. 2 - Guidance for Risk Assessment and Management: Offsite individual risk from Hazardous Industrial Plant.

2. Noise – Environmental Protection (Noise) Regulations 1997 Air Quality – Draft State Environmental (Air Quality) Policy 2009.”

Section 6.7 of the ANSIA Structure Plan describes the application and requirements of buffers within the ANSIA. Specifically the Structure Plan includes a general 3000m ‘Risk, Noise and Air Quality’ buffer around the Strategic Industrial Area and a standard 1000m ‘Land Use Sensitivity’ buffer around the Transient Workforce Accommodation sites.

The Shire of Ashburton Council at its Special Meeting of 5 October 2011, resolved to adopt the Structure Plan and it was subsequently endorsed by the WAPC on 31 October 2011.

This Development Plan conforms to the broad land use zones identified on the Structure Plan and addresses the relevant planning requirements identified within the document.

2.3 AMENDMENT NO. 10

Amendment No. 10 to TPS7 provides for the rezoning of the Wheatstone LNG site as well as the proposed common port facility site from the ‘Rural’ zone and ‘Conservation Recreation and Nature Landscape’ reservation to ‘Strategic Industrial’ zone. The Amendment also proposes to rezone land for infrastructure and transport corridors as well as land for a TWA facility.

The Amendment reflects the direction of the ANSIA Structure Plan and Appendix 11 of the Scheme.

The Amendment is relevant to planning for Stages 1B and 1C in that the reservation of land comprising the eastern MUAIC and its connection with Onslow Road will facilitate access to the Stage 1B and 1C precincts and the broader ANSIA. The Amendment is also relevant in that it will facilitate the development of the port and CUCA, which will service development within Development Plan area.

Council, at its Special Meeting of the 5 October 2011, considered proposed Amendment No. 10 whereby the Council resolved to adopt Amendment No. 10 to the TPS7. Final approval was subsequently granted by the Minister for Planning on 25 October 2011 and gazetted on 22 November 2011.

2.4 PROPOSED AMENDMENT NO. 17 (STAGE 1B)

Proposed Amendment No. 17 to TPS7 provides for the rezoning of the Macedon Domestic Gas

project, and the proposed FIA from the ‘Rural’ zone and ‘Conservation Recreation and Nature Landscape’ reservation to ‘Strategic Industrial’ zone. The Amendment also proposes to rezone land comprising the Western MUAIC as well as land for a second TWA facility (RefeR to figuRe 5). As the nature and scale of future development is currently unknown, the alignment of the Western MUAIC is indicative and subject to detailed planning at Development Application stage. The Scarborough LNG project does not form part of Amendment No. 17 and will be subject to a future Scheme Amendment.

The Amendment reflects the direction of the ANSIA Structure Plan and Appendix 11 of TPS7.

2.5 PROPOSED AMENDMENT NO. 18 (STAGE 1C)

Proposed Amendment No. 18 to TPS7 provides for the rezoning of the Stage 1C area from the ‘Rural’ zone to ‘Industry’ zone (RefeR to figuRe 6). Stage 1C is envisaged to be developed to comprise a range of industrial activities which offer support services to industries within the ANSIA, off shore activities, as well as any other support services required in the region. The proposed ‘Industry’ zone will also provide the opportunity for industrial, transport and support service companies, currently located in the Beadon Creek Industrial Area, to expand or relocate to this GIA.

The Amendment reflects the direction of the ANSIA Structure Plan and Appendix 11 of TPS7.

3.1 SITE CONTEXT

The Development Plan area comprises approximately 2,862 hectares of Crown Land situated 11 kilometres south-west of Onslow and 2 kilometres east of the Ashburton River on the Pilbara Coast. Exmouth is some 100 kilometres to the south-west, whilst Karratha/Dampier are located some 310 kilometres by road to the north-east. The main access to the site is via the North-West Coastal Highway and Onslow Road.

3.1.1 existing RoAds

Onslow is accessed from Onslow Road which in turn connects with the North West Coastal Highway. The proposed ANSIA access road will connect with Onslow Road approximately 16 kilometres south of the Onslow town site. The following provides an overview of these roads.

3.1.1.1 North West Coastal Highway

The North West Coastal Highway (NWCH) is a primary road under the control of Main Roads Western Australia (MRWA). The NWCH links Geraldton to Port Hedland. At Port Hedland the route continues as the Great Northern Highway.

The NWCH is constructed with a standard 7.2 metre wide carriageway and 1.0 metre shoulders.

Traffic data provided by Main Roads indicates a daily traffic volume of 457 vehicles per day of which 35% are classified as heavy vehicles. The count data shows 183 vehicles per day (vpd) head north (40% Heavy) and 274vpd head south (31.8% heavy). The traffic count location is to the north of Nanutarra Munjina Road and the data was recorded between 25 August and 4 September 2007.

A count has also been provided for the NWCH north of Pannawonica Road showing 650vpd, of which 301 head north (32.9% heavy) and 350 head south (37.7% heavy). The data was recorded in October 2009.

3.1.1.2 Onslow Road

Onslow Road is the only sealed road accessing the town site of Onslow. It is a primary regional road linking the town of Onslow to the North West Coastal Highway. The section between the NWCH and Beadon Creek Road is under the control of MRWA. At present it has a 6.0 metre wide sealed carriageway.

Traffic data provided by MRWA shows a daily volume of 106 vehicles west of Minnie Station Road (June 2010) of which 55 head north (21.8% heavy) and 52 head south (23.1% heavy). A count is also available north of Twitchin Road showing 213vpd, of which 107 head north (15% heavy) and 106 head south (15.9% heavy).

18

MRWA is currently upgrading Onslow Road to allow for a 7.2 metre wide carriageway with 1.0 metre shoulders. Works commenced in November 2011, with considerable progress being made before Christmas 2011. The upgrades will affect that part of Onslow Road between the NWCH and the future road intersection for ANSIA.

3.1.2 existing LAnd Uses

The Stage 1B area currently falls within the ‘Rural’ zone, with a small portion in the north western corner of the development plan area being zoned ‘Conservation, Recreation and Natural Landscapes’. The Stage 1C area falls entirely within the “Rural’ zone. The area largely comprises tidal mangrove mudflats, which progress inland from the coast to periodically inundated claypans through to low hills of sparsely vegetated dunes in the south (ENV, 2011).

Two historic jetty sites and the remains of the old tramline and onshore navigation beacon were identified during a detailed archaeological study, and these fall within the ANSIA Structure Plan area, however these are largely contained with the area allocated to Stage 1A.

3.1.3 sURRoUnding LAnd Uses And FeAtURes

The areas surrounding the ANSIA Structure Plan area are largely zoned ‘Rural’ under TPS7, with the exception of a portion of land to the north-west, which is zoned ‘Conservation, Recreation and Natural Landscapes’.

The Old Onslow Town Site and Onslow Cemetery is located to the west of the subject site, which are registered on the Western Australian State Register of Heritage Places. The rest of the areas to the east and south of the subject site largely contain low-lying hills with sparse vegetation.

The existing Onslow Industrial area, which is located to the south-west of the existing Onslow townsite caters for a range of light industrial uses. These include local service trades, laydown areas as well as airport and marine services to the existing Onslow airport and Beadon Creek Harbour.

3.2 ENVIRONMENTAL

ENV was initially commissioned by LandCorp to undertake a preliminary biological desktop assessment of the ANSIA (RefeR to APPeNdix 2). The purpose of the report was to compile and review the existing body of knowledge on flora, vegetation and fauna in the Onslow/ANSIA area in order to identify any environmental constraints and identify any gaps in the work already undertaken.

The report identified a lack of data on the presence of rare and priority flora, vegetation and fauna habitats and recommended that additional survey efforts be undertaken to address the gaps.

Subsequently, ENV was commissioned to undertake detailed Flora, Vegetation and Fauna Assessments of the ANSIA to address these gaps.

19

3.2.1 topogRAphy

The northernmost boundary of the study area is located approximately 3 kilometres south of the coastline. Traversing from the coast southward through the ANSIA area, tidal mangrove mudflats progress landward to periodically inundated claypans through to low hills of low semi-lithified sparsely vegetated sand dunes.

Along the Ashburton coast, a trend of coastal dunes semi parallel to the coast (northeast to south-west) has evolved with a width of about 1 kilometre. The maximum height of the Aeolian thinly vegetated dunes that cross ANSIA Stage 1B is approximately RL 14m AHD.

South-east of the Old Onslow Township and at the north of Stage 1B area, a coastal sand dune ridge traverses the site. Proceeding south through Stage 1B, a low lying supratidal area lies south east and between the current coastal sand dune; coastal ridge and a former coastline dune system; former coastal ridge, which now lies approximately 4km inland. The supratidal area has an elevation of approximately RL 2m AHD and was reported to be inundated during field investigations performed by Golder & Associates (Golder) on the BHP Macedon site in March 2010.

The Ashburton River floodplain has a near-horizontal surface and is elevated at relative level (RL) of 4m Australian Height Datum (AHD) where it crosses Stage 1B at the southwest corner.

The central south portion of Stage 1B has a ground surface of an approximate minimum RL of 3m AHD within a large clay plan.

The Stage 1C area is located approximately 7 kilometres south of the coast and approximately 4 kilometres east of the Stage B area. The western GIA has an approximate minimum RL of 4m AHD along the northern side, and rises to approximately 7m AHD toward the southern end of the site adjacent to the MUAIC. The eastern GIA is relatively flat and has a minimum RL of 7m AHD across the majority of the site, which begins to decline along the eastern boundary of the site.

3.2.2 LAndFoRms/geomoRphoLogy

Golder (2010) identified the following general geomorphic features across the ANSIA area:

i. Coastal Ridge: Coastal sand dunes act as a barrier at the current coastline. The long axis of the dunes is aligned south-west to north-east. The ridge is comprised of accreting material as part of a prograding coastline. The material could have possible high fines content due to aeolian re-working of Ashburton River deposits;

ii. Supratidal Flats: Low lying Supratidal Flats are active and were observed in March 2010 (Golder 2010) becoming inundated on high tides. Approximately north-south oriented flowing tidal salt water streams that flood and drain the supratidal flats are apparent;

20

iii. Low-Lying Clay Pans: Accumulation of fine sediment in low-lying areas due to flooding and storm surges. The clay pans appear to have two modes of origin, namely: (i) a back lagoonal system separated from the shoreline by a barrier dune; and (ii) a slightly tidal backwater associated with creeks extending into the Supratidal Flats;

iv. Former Coastal Ridge: Several former coastlines run parallel with the current south-west to north-east trending Coastal Ridge. The former coastlines are continuous on either side of the Ashburton River. Surficial deposits are comprised of sand with high fines content and some beach-rock; and

v. Ashburton River Delta: The Ashburton River is a major sediment source seen from switching of the river course (distributaries) with fluvial sediments and low levee banks as the river meandered across its floodplain. Subsurface conditions in this area comprise variable channelized and levee deposits adjacent to the current river channel.

3.2.3 FLoRA And VegetAtion

Further to the above, ENV has undertaken a Level Two Flora and Vegetation assessment of the Stages 1B and 1C areas (RefeR to APPeNdix 3). The assessment identified a total of 131 taxa from 88 genera and 33 families. Average species richness was 15.7 taxa per quadrat ± 6.1 from a total of 22 quadrats.

No species listed under the Environment Protection and Biodiversity Conservation Act 1999 or gazetted as Declared Rare Flora under the Wildlife Conservation Act 1950, were recorded in the study area.

One Priority Flora listed by the Department of Environment and Conservation was recorded in the study area: Eremophila forrestii subsp. viridis (Priority 3).

Six introduced species were recorded in the study area. One of these species, Mesquite (*Prosopis glandulosa), is listed as a Declared Plant under the Agriculture and Related Resources Protection Act 1976.

Five vegetation associations were mapped in the study area. None of the vegetation associations recorded are listed as Threatened Ecological Communities under the Environment Protection and Biodiversity Conservation Act 1999, as Environmentally Sensitive Areas under the Environmental Protection Act 1986, or as Priority Ecological Communities by the Department of Environment and Conservation.

Vegetation condition ranged from Excellent to Completely Degraded, with most of the study area being described as being in Very Good to Good condition. Disturbance to vegetation within the study area included the presence of cattle, introduced species, tracks, previous clearing and dumped rubbish.

The flora and vegetation present or likely to be present within the ANSIA do not appear to form any statutory constraint to development.

21

3.2.4 FAUnA

ENV has undertaken a Level One Fauna assessment for the study area (RefeR to APPeNdix 4). The study area consisted of three main fauna habitat types: samphire, shrubland of Acacia species over hummock grassland and claypan. These habitats are considered to be of moderate value. The samphire wetland is seasonally likely to host a range of resident and visiting waterbirds and shorebirds, the shrubland is rich in reptiles and the claypan habitat provides drinking opportunities for birds, especially abundant granivorous species such as finches and parrots, as well as macropods and bats.

A total of 34 vertebrate fauna species were recorded during the survey comprising five reptiles, four mammals and 25 bird species. A total of 273 vertebrate fauna were identified by database searches as having been recorded previously within the vicinity of the study area. This includes five amphibian species, 69 reptile species, 170 bird species and 29 mammal species. Many of the species identified from database searches are unlikely to occur in the study area on a regular basis as these records are from a large area encompassing a wide range of habitats, many of which are absent from the study area.

A total of 44 conservation significant fauna (one reptile, four mammals and 39 bird species) were identified as having the potential to use the habitats present within the study area. Twenty-two of these species were considered as ‘Unlikely’ to occur within the study area.

Thirteen of the 44 species are considered as ‘Possible’ to occur within the study area. A further seven species were considered as ‘Likely’ to occur and two species were noted as ‘Present’ in the study area.

Two bird species of conservation significance were recorded during the survey: the Australian Bustard (Ardeotis australis) is listed as a Priority 4 species and the Rainbow Bee-eater (Merops ornatus) is listed by the Environmental Protection and Biodiversity Conservation Act 1999 as migratory, though it also breeds in the vicinity of the study area.

The fauna present or likely to be present within the ANSIA do not appear to form any statutory constraint to development.

3.2.5 Acid sULFAte soiLs

ENV has undertaken a Preliminary Acid Sulfate Soil (ASS) assessment of the subject area (RefeR to APPeNdix 5). The report concludes the following:

• ASS is variably present across all thegeologic units of the ANSIA;

• TestingforASSin‘gap(oruntested)areas’by a broad approach would not provide greater confidence of ASS risk as lithologies are highly variable within the same geologic units. PASS testing in ‘gap areas’ would be a costly expense without merit if performed broadly;

22

• FocusedASStestingisrecommendedwhenspecific design plans are available. Such ASS work is focused on subsurface utility corridors and such, could be coordinated with the geotechnical testing work to achieve cost saving efficiencies; and

• Mostsuitableborrowmaterialsarelocatedabove the water tab le (greater than approximately RL 1.5 m) and are dry.

3.2.6 dUst mAnAgement pLAn

As per the ANSIA Structure Plan, air quality and emissions are to be assessed and managed by the proponents of a development plan. These air quality modeling and management plans are to be industry specific and given that the exact nature and scale of development is yet to be identified for Stages 1B and 1C, it is reasonable that a detailed dust management plan would not be required at this stage. This is to be addressed by specific proponents upon submission of a Planning Application for a specific land use, to the satisfaction of the Shire and the Department of Environment and Conservation.

3.2.7 eFFLUent disposAL

Climate Change Response Pty Ltd (CCR) was commissioned by LandCorp to conduct an assessment of the Industrial Ecology component of the Development Plan (RefeR to APPeNdix 6). CCR stated the following in regards to effluent disposal:

“The south-western corner of the Stage 1B area is allocated to a waste water treatment precinct. This is because it is low lying and so is suited to gravity feeding of waste water and sewerage, it is not a suitable shape for conventional industrial development (which usually require much squarer lots), and does also not have easy access to the western road and services corridor reducing its ability to accommodate higher risk industrial use. It will initially house the ANSIA wastewater and sewerage treatment plant. However as the ANSIA becomes more fully developed it will also be able to house a wastewater recycling plant similar to the KWRP plant in Kwinana.”

The draft Concept plan for the ANSIA has not yet been adopted by the relevant State Government Agencies and is intended as a guide for future planning. It should be noted that the draft Development is subject to detailed planning and approval by the Water Corporation and Department of Water.

3.2.8 impActs oF pRoposAL on nAtURAL enViRonment

3.2.8.1 Flora

Five vegetation associations were identified within the study area; three representing sand dune communities (vegetation associations 3, 4 and 5), one clayey plain community (vegetation association 2) and the remaining vegetation association comprised samphire species (vegetation association 1).

23

All vegetation communities were identified as having been affected by disturbance, which includes introduced species, tracks and dumped rubbish as well as trampling and grazing by cattle. Vegetation association 5 however, was identified as being I excellent condition and was the least affected by disturbance.

As previously mentioned, none of the vegetation associations recorded within the study area are afforded any conservation significance. The vegetation associations recorded within the study area are considered to be representative of vegetation units that are widespread within the Carnarvon region, and therefore the impact from the development of the ANSIA is not considered to adversely impact the natural flora.

3.2.8.2 Fauna

Two birds of conservation significance were recorded in the study area; the Australian Bustard and Rainbow Bee-eater, which area considered relatively common in the Ashburton area. The Australian Bustard and Rainbow Bee-eater are highly mobile birds. Habitat loss and alteration, and predation by cats and foxes are believed to be impacting populations of the Australian Bustard. The Rainbow Bee-eater is listed as migratory by the EPBC but is known to breed in Onslow. Populations from south-west WA migrate north before winter. The development of the ANSIA is unlikely to adversely impact these species in the local or regional setting.

A survey in the vicinity of the Macedon site recorded 21 fauna species of conservation significance; including 14 Palearctic migrant shorebirds (most of these would not use habitat in the current study area). Several coastal species were also recorded, including the Estuarine Crocodile, Common Tern, White-bellied Sea-eagle and Eastern Osprey, all of which would occur in coastal habitats, outside of the ANSIA. Records of Flock Bronzewing and Star Finch were identified by Bamford1 suggest that these birds may occasionally use the ANSIA. These birds are nomadic and highly mobile, having been recorded through much of inland northern Australia. Therefore development in the Stage 1B and 1C areas is unlikely to impact the overall conservation status of these species.

Fifteen bird species of conservation significance were recorded in the vicinity of Ashburton, dominated by migrant shorebirds and waterbirds, all of which are wide ranging migratory or nomadic birds that have high dispersal abilities and are unlikely to rely on habitats within the ANSIA.

24

A survey by Biota2 recorded six conservation significant species in the Ashburton area, including the Little Northern Freetail-bat, Western Pebble-mound Mouse, Fork-tailed Swift. The Little Northern Freetail-bat and Fork-tailed Swift are aerial species that may use the area for foraging. Development of the ANSIA may reduce the extent of habitat available for these species but it would be unlikely to alter the regional or national conservation status of these species. There is also no suitable habitat for the Western Pebble-mound Mouse within the ANSIA, therefore it is unlikely to be impacted by the proposed development.

3.3 GEOTECHNICAL

Galt has undertaken a geotechnical desk study review of the subject area (RefeR to APPeNdix 7). The study identifies soil and rock stratigraphy across the area comprising the following geological units as defined by Coffey Geotechnics and subsequently refined by Golder Associates (Golder)3:

“Unit 1 (Surface to ~RL -4 m AHD)

Aeolian sand (with clayey and gravelly strata), loose to medium dense, thickness varies from 0 m to >15 m; and

2 Biota Report Reference: Biota Environmental Services (2010) Wheatstone Project Flora and Fauna Assessment Addendum. Unpublished Report for URS Australia.

3 Golder Associates Report Reference 097642446-018-R-Rev1: Wheatstone Phase 3 Downstream Geotechnical Investigation – Final Evaluation Report – Onshore, prepared for Chevron, dated 18 February 2011.

Calcareous rocks (calcarenite, sandstone, caprock and beachrock), typically low to high strength rock, thickness varies from 0 m to about 10 m; overlying

Unit 2 (Marine and Alluvial Deposits) (surface to ~RL-1m AHD)

The Unit 2 soils are either exposed in the tidal mudflats or underlie the edges of the Unit 1 sand layers. The Unit 2 soils comprise:

• Unit2a: verysoftandsoftsiltandclaywithvarying amounts of organics, can be up to about 3 m thick; and

• Unit2b: very loose to dense granulardeposits (sand, shells and gravels).

Unit 3a (Ashburton Red Beds – Soil) (~RL-4 m to ~RL -10 m)

Clayey sand and sandy clay, stiff and very stiff, low to medium plasticity becoming high plasticity with depth, cemented rock‐like lenses in places, extending to about RL ‐10 m AHD; overlying

Unit 3b (Ashburton Red Beds – Weak Rock) (~RL-10 m to ~RL -25m)

Claystone, sandstone, siltstone and conglomerate (typically cemented Unit 3a soils), extremely low to medium strength (with soil-like lenses); overlying;

25

Unit 4 (Carbonate Rocks) (~RL-25 m to ~RL-70m)

This unit comprises a variety of carbonate rocks of very low to high strength. A 5 m thick weathered zone occurs near the top of the stratum (possibly related to a historical water table or sea‐level). This unit is distinguished from the Unit 3b rocks by the pale colours and high carbonate content. This unit extends to about RL - 70 m and overlies;

Unit 5 (Glauconitic Rocks) (>~RL-70m)

Claystone, siltstone and sandstone, very low to low strength rock, greenish in colour.”

The report identified that the developable areas can be divided into two distinct geotechnical zones:

• Dune Zone: “characterised by surface levels typically higher than about RL 4 m and is underlain by Unit 1 (soils and rock) (more than about 8 m thick) followed by the Unit 3, 4 and 5 strata”; and

• Sandplain: “typically has a thinner layer of Unit 1 Sand which is generally underlain by Units 3, 4 and 5. However, localised Unit 2 lenses (i.e. soft / loose deposits) can be present below the Unit 1 sand. These typically occur near the edges of the mudflats or the claypans. The claypans are typically flat, roughly circular/oval features which are underlain by finer grained materials (Unit 3a clays) and surrounded by a perimeter of dune sand.”

The report states that footings or piling will likely be required however it is dependent on the ground conditions, and the ultimate nature of the development (i.e. design loads, movements that can be tolerated). The best areas for development (geotechnically) are the higher-lying Dune Zones where it is unlikely that piling will be required except, possibly, for highly loaded or highly settlement-sensitive structures/plants. The sand and rock in these areas is likely to be suitable for use as a relatively good quality fill.

In reviewing the Galt report, it should be noted that at the time of preparation of the report, the proposed GIA’s were contained within Stage 2 of the ANSIA. They are now included in Stage 1C of the ANSIA and referred to as such in this report.

3.4 HYDROLOGY

3.4.1 FLood WAteR Risk mitigAtion stRAtegy

The different proponents designs, layouts and pad levels, where known, have been incorporated into the hydraulic flood path modeling, undertaken by BG&E (RefeR to APPeNdix 8). Assumptions have been made about the likely extents and pad levels where planning is not as advanced (e.g. throughout Stages 1B and 1C). The resulting flow paths and velocities have been analysed with the aim of identifying the areas that can be filled/developed without impacting the natural hydrology.

The ANSIA is situated in low-lying ground and in the Ashburton River floodplain. All modelling undertaken by BG&E shows that water is

26

stagnating east and west of Stage 1B. Stage 2, which incorporates the Stage 1C area, is located downstream of the Ashburton River major flow break outs and some low lying areas upstream of the tidal flats are inundated and in Extreme Hazard category (flood risk) in an undeveloped state.

The staged development shows that the impacts from road development differ from the impact with all land development combined, and highlights the need for an integrated planning approach. The resulting flow paths and velocities have been analysed with the aim of identifying the areas that can be filled without impacting the natural hydrology of the subject site.

Proposed development that is outside the floodway is considered acceptable with respect to major flooding. However, in areas subject to flooding a minimum finished ground level of RL0.5m above the 1 in 100 AEP (annual exceedance probability), is recommended to ensure adequate flood protection.

3.4.2 dRAinAge stRAtegy

Given the risk of the Ashburton River bursting has been predicted to have a significant impact on development, BG&E have assessed the potential impacts of surface water flows on the identified development sites (RefeR to APPeNdix 9). The following strategies were devised to manage surface water drainage in the event of a flood or inundation:

• The pad level of each lot may to be elevated above the 1 in 100 year ARI water level with 0.5m freeboard provided.

• Major natural waterways around the development sites are to be reserved to allow water to discharge through the development areas without inundating lots. Five naturally existing waterways have been identified to discharge 100-year floor events without adversely impacting development sites.

• Volumes for either detention basins or infiltration swales that are required for the detention of ARI 1 year 1 hour runoff and attenuation of ARI 5 and 100 year peak flows were calculated for each site. Approximately 1m3 volume of detention basin or infiltration swale is required for every 300m2 development area in order to contain ARI 1 year 1 hour duration rainfall runoff.

• Every discharge point of the development area to the broad environment needs to be monitored as well as the water towards the inlet of the wastewater treatment plant (WWTP). The treated water at the discharge point of the WWTP is also to be sampled and analysed on a regular basis.

• An Urban Water Management Plan (UWMP) is to be prepared for the second TWA site (Stage 1B) in accordance with the Department of Water’s Urban Water Management Plan: Guidelines for Preparing Plans and Complying with Subdivision Conditions.

Further to the broad mitigation measure identified above, drainage infrastructure is to be constructed with appropriate side slopes to minimise erosion and in turn, the risk of increased sedimentation downstream. The following design parameters are suggested:

• Longitudinal grade of 1:1000 to reduce velocity and erosion.

27

• Rock protection in bends to reduce scour.

• Adequate planning practices with buffer zones to protect riparian zones of natural creek as well as wide road reserves.

• Landscaping with native plants.

• Maintenance of vegetated swales and verges.

• Protection around culverts.

3.4.3 LocAL WAteR mAnAgement stRAtegy

BG&E were commissioned by LandCorp to develop a Local Water Management Strategy (LWMS) for the Stage 1B and 1C areas (RefeR to APPeNdix 9). The LWMS identifies water management strategies for groundwater and surface water sources, desalination and wastewater. The purpose of the LWMS is to ensure that the requirements and objectives outlined in a range of planning documents are met during the planning process and subsequent engineering and design studies for the ANSIA. Some of these documents include SPP2.9 – Water Resources, Liveable Neighbourhoods and the Stormwater Management Manual for WA.

The LWMS provides guidelines for the following matters:

• “Fit-for-purpose water use strategy to conserve potable water, minimize wastewater and re-use all forms of water, including storm water;

• Quantification of land required for storage (detention) of stormwater for the critical 1 in 100 year ARI and 1 in 10 year ARI for commercial areas;

• Identification of land required for retention of the 1 in 1 year, 1 hour ARI storm event and treatment of all run-off contained in the drainage infrastructure network;

• Calculation of the proportion of constructed impervious surface;

• Infrastructure and management requirements and proposed locations for proposed water, wastewater and stormwater systems, having consideration of infrastructure already existing and identifying any necessary approvals;

• Map of existing groundwater levels and any proposed controlled groundwater level (including use of subsoil drains and treatment prior to discharge) with justification for this control;

• Demonstrated understanding of the concepts and key issues associated with choice of stormwater controls;

• Identification of types of best management practices for management of water quality and quantity;

• Where a constructed water body is proposed, this should be depicted on the structure plan, together with information in the local water management strategy outlining the purpose and design of the water body, and a proposed schedule for management and ongoing maintenance, including the recommended transfer process to local government and funding requirements and options;

• Issues to be addressed at subdivision stage (included in an urban water management plan); and

28

• Recommended monitoring framework, pre- and post-development.”

The diverse range of scenarios modelled by BG&E demonstrate the tendency of water to flow towards the existing non-perennial creeks and low-lying flats around the ANSIA. It is therefore recommended that the old paleo-channels be maintained with adequate buffering areas to allow for a rapid drainage of the flow towards low lying areas and the coast.

Proposed development outside the floodway is considered acceptable with regards to major flooding. The 1 in 100 AEP flood level for areas subject to tidal flooding is estimated to be 2.14m AHD, including 0.9m of sea level rise. A freeboard of 0.5-0.6m above the 1 in 100 AEP is recommended to account for variations caused by wind and wave action and other local variations of flood levels.

3.5 HERITAGE

3.5.1 histoRic

TPG Heritage has undertaken a European Heritage Technical Study Report to identify whether there are any historic heritage sites within the study area (RefeR to APPeNdix 10). The report identified that a portion of Old Onslow Townsite, which is listed on the State Register of Heritage Places and is afforded protection under the Heritage of Western Australia Act 1990, will be impacted by the development of Stage 1B.

Stage 1C is located a significant distance from

the registered curtilage and is therefore not expected to have any impact on the cultural heritage value of the Old Onslow Townsite.

The Heritage Council’s registration not only covers the main former Old Onslow Townsite but it also extends along the former Ashburton Sea Port tramline to the former jetty along the coast. The Old Onslow Townsite and cemetery, which forms the largest component of the registered curtilage, lies outside the ANSIA. Archaeological remains of the former Ashburton Sea Port telephone line, the former Ashburton Sea Port tramline, a 1909 large timber bridge and associated debris traverse the Stage 1B area and may be impacted.

The Report identifies a number of strategies for the management of these identified elements.

Ashburton Sea Port Telephone Line:

• The telephone bases within the Stage 1B area should be removed prior to the commencement of construction works. The removed artefacts should be vested in the care of the Shire of Ashburton or the Onslow Goods Shed Museum. A permit under section 79 (2) of the Heritage of Western Australia Act 1990, is to be obtained from the Heritage Council of Western Australia prior to the removal of the bases.

1909 Large Timber Bridge:

• The 1909 large timber bridge should be retained in situ.

• New structures located in the immediate vicinity

29

of the 1909 large timber bridge should be designed to minimise impact on the remaining timber structures.

• An archival record of the 1909 large timber bridge including details of its construction is undertaken prior to the commencement of construction works.

Artifact Scatter:

• Fieldwork undertaken to date has resulted in the discovery of debris across the project area. Mitigation measures are required to ensure that any unidentified debris/artefacts remaining in the project area are appropriately managed.

Accordingly, prior to the commencement of construction works an archaeologist should be engaged to develop a specific Archeological Strategy for each development site, to identify the potential for further debris/artefacts to be located in the area. The archaeologist should identify potential areas for archeological deposi ts and develop strategies to be implemented as part of a watching brief to ensure that any debris/ artefacts located during the works are appropriately managed.

Hydrology:

• Any changes to the natural hydrology of the area, resulting from the cut and fill required for the development of Stage 1B, should mitigate against any potential impact on the 1909 timber bridge and the Old Onslow Townsite.

3.5.2 indigenoUs

All development within the ANSIA will be subject to Aboriginal Heritage surveys being undertaken in accordance with the Aboriginal Heritage Act 1972.

New proponents locating in Stage 1B will be required to engage with the traditional owners in relation to their own developments. BHP Billiton’s Macedon Plant has already completed this requirement.

Communication with the traditional owners, Buurabalayji Thalanyji, has commenced regarding Stage 1B and 1C, with the first scheduled meeting expected to occur in February 2012. The meetings aim to address Aboriginal Heritage survey investigations and Native title.

A search has been undertaken on the Department of Indigenous Affairs website which shows the following sites and surveys listed over the Stage 1B and 1C areas:

3.6 TRAFFIC AND CIRCULATION

Riley Consulting was commissioned by LandCorp to consider and report on the traffic and transport impacts of developing the ANSIA (RefeR to APPeNdix 11). The findings of the report are outlined below.

3.6.1 tRAFFic impAct Assessment

The forecasted traffic volumes are included in table 1 to consider whether, from a general planning perspective, any roads require upgrading.

Table 1 – Regional Roads Review Summary with Full Development (source: Riley Consulting)

Road Type Volume Increase Comment

North West Coastal Highway

1 650 <210* Operation within acceptable levels

Onslow Road to Highway

1 106 214 Operation within acceptable levels

Onslow Road to Onslow

1 213 5,240 Operation within acceptable levels

ANSIA Access Road

1 <150 5,450 Operation within acceptable levels

*Traffic will head east and west

The expected traffic demands on the ANSIA access road and Onslow Road are considered to fall within the desirable daily flows for a type 1 road. Onslow Road is currently being upgraded to a type 1 standard, and as a new road constructed to MRWA standards, the ANSIA access road would also be of a type 1 standard. Current road planning is suited to cater for the forecast traffic demand of the full development of the ANSIA and therefore it is deemed that no road can be expected to operate in a manner contrary to its function.

Riley Consulting has advised that the regional road network is not indicated to require upgrading, beyond current upgrading plans, to accommodate development of the ANSIA.

3.6.2 pRoposed RoAd LAyoUt And constRUction

BG&E Pty Ltd (BG&E) was commissioned by LandCorp to undertake a route selection study of the proposed Western MUAIC (RefeR to APPeNdix 12). The study evaluated six options for the western corridor, with each alignment being selected based on a preliminary desktop study.

The western MUAIC is necesary to allow for safe transport of goods throughout the ANSIA, which are not able to be transported along the eastern MUAIC due to risk of contamination for Onslow Salt.

A desktop assessment of the constraints and opportunities was undertaken against the following four key criteria:

34

• Land Use;

• Engineering;

• Proximity to proponents’ plant Risk Zones; and

• Cost.

An assessment of the impact each route has on the hydrology of the surrounding area was also made. The key criteria were identified via stakeholder consultation undertaken with a number of government agencies. This provided input into a simplified multi-criteria assessment, which identified a preferred alignment.

Based on strategic advantages, multi criteria assessment and cost comparisons, Alignment Option E (as presented in the study) is supported as the preferred alignment option as it serves to favourably connect the whole western part of the site along its length, providing good access to the middle and western portions of the site. The alignment also has a low severance impact and result in a moderate earthworks deficit and moderate construction cost. The timing of construction of the Western MUAIC will be subject to demand.

The MUAIC alignment identified in the Development Plan is consistent with Alignment Option E.

The MUAIC is to be designed cognisant of a speed limit of 110kph. Whilst it is noted that 110kph is a high speed to be contemplated for an industrial access road, it requires that all road facilities are designed for a speed of 120kph (posted speed plus 10kph). Along the western MUAIC it is recommended that the

speed limit be reduced to 80kph.

Future access roads, traffic and transport considerations associated with the detailed development of the Stage 1B and 1C areas are to be identified and addressed upon submission of a Planning Application, to the satisfaction of the Shire and MRWA.

3.6.3 tRUck pARking/LAydoWn AReA

Through discussions with Chevron and BHPB, it became evident that there may be a demand for truck parking and road train laydown areas in the ANSIA, that were available for use by contractors or other vehicles making trips to the major proponents’ sites. There will also be a demand for truck parking for large trucks and road trains making trips to the General Industrial Areas.

It is intended that a permanent truck parking facility will ultimately be provided in the GIA, possibly collocated with a petrol filling station. Until such time as subdivision and development of an appropriate location in the GIA is available, it is considered prudent to identify appropriate locations for temporary truck parking locations that can be constructed and built within the ANSIA access road reserve.

Riley Consulting has prepared a Technical Note (refer to Appendix 13), which identifies potential locations for truck laydown facilities that are appropriately dimensioned and located, such that they comply with Main Roads WA’s approval requirements, should an interim facility be found necessary.

35

Other key suggestions include:

• The location should be on the departure side of the road (outbound from the ANSIA) and as near as possible to Onslow Road as possible, as the facilities are expected to service the ANSIA and Onslow town site;

• An interim informal facility is likely to be required in the short term to cater for construction vehicles and may be required prior to the completion of the first GIA;

• An informal truck parking/laydown area to accommodate approximately 10 trucks should be provided to the northern side of the ANSIA service road in the vicinity of the eastern GIA; and

• Larger formalised truck parking/road train assembly areas can be planned for inclusion within the eastern GIA..

3.6.4 Access

Throughout the ANSIA access road, where speed limits of 110kph apply, Riley Consulting has identified the following design requirements based on the provision of turning lanes into each of the development sites from the MUAIC:

• Right turn lane lengths of 275 metres;

• Left turn lane lengths of 205 metres;

• Right – Left access to be spaced at least 40 metres apart, however 180 metres is preferred where a left turn lane is to be provided, and cross traffic expected;

• Where turn lanes are proposed on the same side of the road, it is desirable that access be spaced 300 metres apart;

• Left – Right access to be spaced at least 550 metres apart (570 metres preferable); and

• Clear zones of between 6 and 9 metes should be provided.

Where the speed limit is reduced to 80kph, further west along the MUAIC, the following design requirements have been identified:

• Right turn lane lengths of 180 metres;

• Left turn lane lengths of 120 metres;

• Right-left access to be spaced at least 40 metres apart, although 180 metres is preferred where a left turn lane is to be provided;

• Where turn lanes are proposed on the same side of the road, it is desirable that access be spaced 200 metres apart;

• Left-right access to be spaced a minimum of 380 metres apart; and

• Clear zones of between 2.5 and 6 metres should be provided.

36

The Development Plan identifies possible access locations into the GIA’s and development sites (subject to approval by MRWA). The access locations are based on the recommendations from Riley Consulting and ensure sufficient separation, turn lane lengths, and appropriate access points can be provided whilst maintaining appropriate levels of safety and traffic movement efficiency along the MUAIC. However more detailed planning of these internal movement systems is to be addressed at Development Application stage, given that no specific proponents have been identified at this stage.

3.6.5 VisibiLity

The most significant safety issue at any intersection or crossing of a major road is the provision of adequate visibility. Austroads requires the following visibility distances to be achieved for intersections throughout the ANSIA, assuming no site gradient:

• At 80kph, the minimum safe intersection sight distance (SISD) is 181 metres; and

• At 110kph, the minimum SISD is 300 metres.

Other sight requirements exist for the side road approach, which are achieved if full SISD is provided. Note that the vertical profile of the ANSIA access road will require further assessment to ensure the above visibility requirements can be achieved. This is to be completed at Development Application stage.

3.6.6 impActs on sURRoUnding moVement netWoRks

The development of the ANSIA will impact on traffic movements in the Onslow Townsite. However, the majority of these impacts will be from employees who rent or purchase new housing in Onslow. LandCorp is currently progressing the planning for the expansion of the Onslow town site and it is anticipated that traffic impacts on Onslow will be addressed as part of the Development Plan for Onslow.

Commercial traffic associated with the ANSIA may have impacts on the Onslow Townsite, including:

• Vehicles seeking fuel if no service station is provided at ANSIA;

• Workers seeking food and provisions;

• Employee accommodation;

• Increased hotel occupancy due to FIFO operations; and

• Increased bus movements between ANSIA and the town centre.

Discussions with the Shire indicate potential issues with construction traffic using Old Onslow Road and Twitchin Road. The future traffic using the ANSIA access road is not considered to be of concern as it will be a new road constructed in accordance with Main Roads’ standards.

37

3.7 SOCIAL

3.7.1 sociAL impAct Assessment

It is widely recognised that the expansion of Onslow and the development of the ANSIA are inextricably linked. The GIA is to be developed by LandCorp as part of the ongoing development (including the Onslow Townsite expansion) that will support the activities to be established in the ANSIA and reduce the impact on the town of Onslow.

Based on extensive discussions with the Shire and WAPC, LandCorp has prepared a Social Impact Statement (SIS) in accordance with the Shire’s Local Planning Policy (refer to Appendix 14). The SIS addresses the potential social impact of future industrial development at the ANSIA and defines the commitment of LandCorp to undertake a significant planning and land release to allow for the creation of 1,500+ residential lots in Onslow.

This will culminate in a town based Development Plan being lodged in mid 2012 with an aim to have it approved early 2013. In parallel, LandCorp is undertaking a land rationalisation exercise throughout the existing townsite to develop and release a number of vacant land parcels that will provide for approximately 30 dwellings at the end of 2012.

3.7.2 WoRkFoRce mAnAgement pLAn

It is anticipated that the Development of Stages 1B and 1C has the potential to create approximately 2,500 full time, non-construction

jobs (including the development of the Scarborough LNG plant), with an even greater number of transient workers being employed during the construction phase of the ANSIA. Therefore, the second TWA is necessary to accommodate the relative large construction workforce required as well as limit the impact on Onslow, which is unable to provide the available land, housing and facilities. The TWA will be allocated as being within the ‘Special Use 2’ zone and be subject to the same provisions as the existing Wheatstone TWA, which is currently within the ‘Special Use 2’ zone.

The TWA will likely be a self-contained development incorporating appropriate services, and recreational/entertainment facilities, and designed to enable the safe retention and protection of personnel during cyclonic events, similar to the Wheatstone TWA.

The ANSIA Structure Plan requires the preparation of a Workforce Management Plan (WMP) that “addresses the impact of the overall development on Onslow (in particular on services and accommodation) and implements appropriate contributions”.

Specifically the ANSIA Structure Plan states that a WMP “will be required to be prepared as part of a Development Plan and detailed in any subsequent planning application. The WMP will address the impacts from the extensive numbers of workers associated with the development of the LNG facilities, CUCA and general industry on Onslow and clearly demonstrate that the proponent is

38

responsible to ensure that all workers under their respective control (including the direct workforce, contractors, sub-contractors and authorised visitors who have direct involvement with the development) are housed either at the ANSIA or in Council approved accommodation”.

Given that no specific uses or proponents are envisaged at this stage, a Workforce Management Plan is to be prepared as part of all future development applications, in accordance with Clause 7.9 and Appendix 11 of TPS7 as well as the ANSIA Structure Plan.

A WMP will be required to be submitted with all subdivision or Development Application, to the satisfaction of the Shire, addressing the requirements outlined in the ANSIA Structure Plan.

3.7.3 LegAL AgReements

The ANSIA Structure Plan identifies that “A legal agreement is to be prepared at the proponents expense (including legal expenses incurred by the Shire) for the purpose of the following:

• All TWA being used only for the accommodation of construction staff, subject to maintenance staff being permitted but only for a 3 week period (after 2 months of operation) when the plant is closed down for maintenance activity. The TWA will be a temporary village facility and remain in-situ for a defined period where all operational staff reside in Onslow.

• Ensuring the necessary arrangements to limit access to Old Onslow for those persons employed and indirectly employed by the

proponent along with methods to actively assist in the conservation of Old Onslow are in place.

• Ensuring the necessary arrangements for the limitation of those persons employed and indirectly employed by the proponent to be permitted in Onslow at any one time are in place.

• Ensuring the necessary arrangements for the implementation of a WMP that addresses the impact of overall development on Onslow (in particular on services and accommodation) and implements appropriate contributions are in place.”

Given that planning for the above matters is to be detailed by the specific proponents, the necessary legal agreement is to be prepared at Development Application stage.

3.8 PLANNING AND DESIGN

The LandCorp ANSIA Industrial Development Plan (the ‘Development Plan’) has been prepared, having due regard to the technical studies discussed above. The emphasis of the Development Plan concept however, is based upon the Industrial Ecology Strategy prepared by Climate Change Response (CCR) (refer to Appendix 6), which was prepared in consideration of the site’s constraints and opportunities.

Industrial ecology refers to smart(er) design and operation of industrial estates from an economic, environmental and community perspective by optimising resources efficiencies through industrial collaboration in order to ensure the long term viability and sustainability of the estate.

39

The Development Plan identifies ‘islands’ of developable land based on the technical studies undertaken, namely the hydrological study which identified overland flow paths. Based on these islands, a concept has been developed for the ANSIA based on best practice industrial ecology principles and demonstrates the potential synergies within the ANSIA, should future proponents deem them to be viable.

Given that BHP (Macedon) is currently the only secure proponent within Stage 1B of the ANSIA, the realisation of the industrial synergies outlined in the Development Plan is dependent upon future proponents’ type and location of development, based on their own independent feasibility studies, which may or may not be in line with the Development Plan concept.

3.8.1 indicAtiVe design pRoposAL

Further to the above, CCR’s Industrial Ecology Strategy was prepared to inform the type and location of the various industrial uses throughout the ANSIA, namely within the Stage 1B area. The concept plan, shown in Appendix 1, was developed based on the following key elements and considerations:

• The hydrogeology of the site identified several ‘developable areas’ across the site;

• The three current proponents occupy the largest developable area on the dunal system that runs from north to south along the spine of the site;

• The ANSIA industries and common user coastal area (CUCA) are to be interlinked by two road and service corridors running from a common access road at the southern end of the Stage 1A

site;

• The downstream gas processing industries expected to be established in the ANSIA are categorised into two groups: those with ammonia as a precursor and those based on gas to liquid fuels conversion;

• The development plan incorporates the following aims from the vision:

“1. The clustering of hydrocarbon processing activities to optimize the cross-flow of product and feedstock with efficient and equitable access to export and import facilities;

2. The efficient and sustainable use of land and infrastructure while incorporating flexibility to respond to changing market requirements to support a rapidly expanding resource sector;”

• In order to optimise sustainability, the development plan incorporates and seeks to optimize the following industrial ecology elements:

1. Utility synergies: Shared use of utility infrastructure, mainly revolving around water and energy (e.g. water supply and recovery, cogeneration) and including industrial and general waste recycling and reuse. This is the main industrial ecology ini t iat ive real isable in the ANSIA;

2. Supply synerg ies : featur ing loca l manufacturer and dedicated supplier of principal reagents for core process industries (e.g. production of nitrogen for industrial use). The main supply

40

synergy is the provision of gas from the LNG and domestic gas processing plants;

3. By-product synergies: The use of a previously disposed by-product (as solid, liquid, or gas, including heat) from one facility by another facility to produce a valuable by-product. This includes CO2 for ammonium urea production, heat for desalination or process heat, and inorganic solid waste byproducts (such as construction and demolition waste); and

4. Service synergies: sharing of services and activities between industries (e.g. joint training of staff and sharing of maintenance contractors including the common visitor and training centre and general industry area(s).

• Themain supply synergy is the supply ofdomestic gas from the LNG and domestic gas processing plants to downstream processing plants, as well as gas turbines in the power generation facility;

• There are 5 distinct clusters and supportareas incorporating the general industrial area and TWA camps. The 5 clusters are:

1. T h e i n i t i a l co re g a s p ro ce s s i n g proponents including:

i. C h e v r o n ’s W h e a t s t o n e L N G processing plant;

ii. BHPBP’s Macedon domestic gas plant;

iii. A 2nd LNG processing facility being considered for the ExxonMobil/B H P B P S c a r b o r o u g h L N G processing plant;

2. T h e p r o p o s e d a m m o n i a b a s e d downstream processing plants including:

i. An export anhydrous ammonia plant (which also supplies the other members of the cluster). This is the anchor tenant required if the ANSIA is to be a successful downstream gas processing area;

ii. One or more ammonia urea plant/s; and

iii. An export ammonium nitrate plant.

3. A proposed gas to l iquids c luster including:

i. Gas to methanol plant;

ii. Large gas to l iquid fuels plant (diesel, naptha etc);

iii. Other related industries.

4. A combined utilities cluster including:

i. A common desalination plant to service the majority of the ANSIA tenants and the Onslow Township.

ii. A common power generation plant precinct to service some of the ANSIA tenants and the Onslow Township;

41

5. A services area including:

i. An offshore supplier laydown area and;

ii. An industrial inorganic byproduct storage and processing and general recycling area.

• The development of the entirety of Stage 1B is expected to be undertaken in three stages:

“1. The initial stage: Where the Wheatstone and Macedon plants with their associated transient workers camps are developed and each is self sufficient with their own water supply, power and waste water treatment plants. The first stage of the general industrial area, the offshore supply base lay down area and the industrial solid waste storage area are also developed. The port will have an LNG loading facility (servicing the Wheatstone plant) and a Materials Offloading Facility (MOF) servicing the construction needs of the Wheatstone and Macedon plants;

2. An interim stage: Where the 2nd LNG processing plant is developed as well as (at least) an export ammonia plant, the general and industrial solid waste recycling facility and a second transient workers camp. All of these are serviced by common desalination and power plants which also service the township of Onslow, with a common waste water treatment facil ity that services the ANSIA. The port has a second LNG

loading facility (servicing Scarborough), a possible western multi product jetty with (at least) ammonia loading facilities and a possible general MOF on the eastern side; and

3. A final stage: Where the ANSIA (stage1 A and B) is fully developed including all of the ammonia, gas to liquids and other plants, a waste water recycling plant and the second stage of the general industrial area. The port has an additional liquid fuels wharf and loading facilities on the eastern side.”

• The key anchor tenant for the ANSIA isan export ammonia plant, which will not only export ammonia, but will also provide ammonia feedstock (and CO2) for a number of other plants including the ammonium urea and ammonium nitrate plant(s). This has been placed at the northern end of Stage 1B as it needs to be located less than 10km from the ship loading point for technical reasons, but also 6-7km for economic reasons. It should also be located as close as possible to the other ammonium plants that it supplies ammonia to and for this reason the ammonia cluster is restricted to the western side of the development.

• Theammoniabasedindustriesareclusteredtogether on the western side of the ANSIA for reasons stated above, and also because the ammonium urea conveyor system should run up the western corridor to minimise potential contamination risks for Onslow Salt.

42

• Duetotheareaconstraintsassociatedwiththe CUCA, the Dampier Port Authority has proposed a wharf and loading facilities on the western side of the port.

• Thegastoliquidsandotherindustriesareclustered in the southern portion of the Stage 1B area (GTL cluster).

• TheGTLclusterisinitiallyproposedtohavethree areas; one to allow a smaller gas to liquids plant, one large area for a large gas to heavy liquid fuels plant and a power and water supply precinct. It is also possible (and likely) that one gas to liquids plant could occupy both gas to liquids areas.

• The southern-eastern corner of Stage 1Bis divided into two lots allocated to “Other Industries”, however it is possible that these may also be used by any large gas to liquids plant in the GTL cluster.

• I f any gas to l iquids plants are to bedeveloped, they are to export their product from a separate jetty in the port area. Due to the constraints associated with the port area, this is to be located on the far eastern side of the port area, near the proposed MOF, east of the Wheatstone and Scarborough Jetties.

• The development of utility synergies isrecommended, whereby larger util it ies are developed and shared by a number of industries, rather than each industry developing individual smaller plants and service lines.

• The desalination and power generationprecincts have been collocated close to the GTL cluster to optimise exchange of waste heat between the power utility and the gas to liquids plants, and the use of off-gases from the gas to liquid plant(s) in the power plant. A very successful industrial synergy has been developed in the Kwinana Industrial Area between the BP Oil Refinery and a gas turbine power plant.4

4 As a cogeneration plant, Kwinana supplies both steam and electrical power. Steam production from the plant is supported by burning refinery fuel gas from the BP Refinery. Waste heat from the gas turbine exhausts is used to drive a steam turbine, further enhancing the efficiency of the plant. The generating capacity of the facility is 122MW at 132kV. At this output the facility can produce 2,300 tonnes per day of process steam with no return of condensate from BP (source: IPR-GDF SUEZ).

43

• A waste water treatment precinct is proposed at the south-western corner of Stage 1B as the topography of the area offers itself to gravity feeding of waste water and sewerage. The shape of the area is also not suited for conventional industrial development (which usually require more regular shaped, square lots) and it does not have easy access to the western MUAIC. As the ANSIA becomes increasingly developed this area will also be able to house a waste water recycling plant, similar to the Kwinana Water Reclamation Plant (KWRP). 5

• The south-eastern quadrant of Stage 1B has been divided into four lots, with the northern lot being allocated as a laydown area for the offshore supply base operators due to its proximity and easy access to the port.

• An industrial solid waste storage and reprocessing and general solid waste recycling and reprocessing area has been nominated at the elbow of the main ANSIA access road. This area is centrally located in the ANSIA and is easily accessible to the main ANSIA access road via the eastern corridor.

5 The KWRP is a joint initiative of the Water Corporation and the Kwinana industries to achieve the double benefit of greater overall water efficiency and reduced process water discharges into the Cockburn Sound. A micro filtration/reverse osmosis unit has been built, which takes secondary treated effluent from the nearby Woodman Point wastewater treatment facility to produce a low TDS (Total Dissolved Solids) water supply. The produced high quality process water is initially used by CSBP, Tiwest, Kwinana Cogeneration Plant, BP and HIsmelt to replace scheme water (6 GL/year, about 2-3% of Perth’s total scheme water use). The low TDS enables the process plants to cut chemicals use in cooling towers and other process applications, thereby reducing metal loads in their effluents. In exchange for taking water from the KWRP, the industries will be able to discharge their treated effluents into the deep ocean outfall through the Water Corporation pipeline, thereby eliminating process water discharges to the sensitive Cockburn Sound (source: Water Corporation).

• The Development Plan allows for, and demonstrates, the various roads, services and pipelines required for the optimal exchanges and access required within the ANSIA, and can be summarised as follows:

1. Each lot has an appropriate ingress and egress road for risk and safety reasons, and also to al low for the eff ic ient transport of goods and services.

2. The service corridors are wide enough to accommodate all expected pipelines, conveyors and other items necessary for efficient exchange of inputs and products between industries and exports through the port.

3. The eastern corridor, with its interface to the port, allows for up to eight liquid fuel pipelines to allow the gas to liquids plants to transfer product to the port for export via the eastern wharf.

4. The western corridor allows for the many input and product exchanges between relevant industries and transport of the products to the port for export. Its interface with the port allows for a sea water inlet pipe and brine return pipe, a sewerage outfall pipe, a cryogenic ammonia pipeline and a urea conveyor.

5. A urea conveyor (with storage sheds in the area west of the Wheatstone site) allows for efficient export of urea via the western multi product jetty.

6. The ammonium nitrate is exported via the western road through the general purpose MOF.

44

• Due to the large amounts of sea water that will be required for the cooling towers and input to the desalination unit(s) within the ANSIA, a large, single seawater inlet line and associated brine return line has been proposed to run from the inlet at the end of the western wharf down the length of the western service corridor. The single pipeline is more efficient and cost effective than running a series of individual proponent pipelines. To enable the benefits inherent in this utility synergy to be realised, one possible scenario is that and the State builds the pipeline as part of the development infrastructure, and recovers the costs from individual proponents as they arise.

1. The seawater inlet and brine return lines could be built in a staged manner in line with the staged development of the ANSIA;

2. To encourage the anchor ammonia tenant to be established, the sea water line could be built initially as far as the proposed ammonia plant site;

3. The seawater pipelines can subsequently be extended further down the western corridor as required by proponents’ plants; and

• The need to extend the seawater pipeline to the ammonia plant also allows the desalination plant to be located in the position shown in the concept Development Plan. This is the best position to allow heat and other exchanged with the surrounding industries (especially the power plant). The cost of providing the inlet water to the desalination plant will be similar, if not less than, the cost of providing a seawater

inlet to the desalination plant located west of the Wheatstone site (the next favoured location within the ANSIA).

• Following discussions with the Department of Mines and Petroleum, the following risk issues that have been considered and responded to in the preparation of the Development Plan include:

• The need for each development site to have clear and unimpeded access to the service corridor;

• The need to create adequate access for emergency services for each of the development sites;

• The need to create buffer zones between each potential major hazard facility and the need to ensure that each site is large enough to individually meet EPA offsite individual fatality risk criteria;

• The need to establish sufficient buffers between industrial plants and the TWA camps so as to not pose a risk to residents of the TWA camps.

• As a result of the industrial tourism analysis for the ANSIA, an opportunity has been identified to build a common visitor centre, training centre and café/lunchbar within the ANSIA to support industrial tourism in the area. This is proposed to be located on the higher ground at the northern end of the Stage 1B area, where views of the ANSIA are maximised. It is proposed that this facility would link closely with the proposed tourism activities of the Shire and also has the potential to be built as a public cyclone shelter.

45

• The Development Plan provides further support for tourism in the Ashburton River area by allowing for the provision of sewerage and potable water services to popular sites on the River. This will allow the Shire to develop serviced caravan and camping facilities, thereby increasing the tourist potential.

It is noted that the information provided by CCR is indicative only and should be used by the State and other Government agencies to inform planning for the ANSIA. The information provided is valuable in identifying industrial synergies, however the allocated development areas are indicative only and are subject to future detailed planning.

The Stage 1C General Industrial Area is proposed to support the establishment and operation of Stage 1A and 1B, including laydown areas, truck parking, transport logistics, service industry, warehousing etc, as provided for the Industry zone in TPS7. It is noted that only limited accommodation potential exists in the Industry zone; a single bedroom caretakers dwelling. Any such planning applications shoul include a clear rationale for the approval of a caretaker’s dwelling on Industrial land.

It is anticipated that development sites within Stage 1C will provide lots ranging from 2 to 15 hectares in area, with the capacity to offer support services to industries within the ANSIA, offshore activities, as well as regional support services to the region and Onslow Townsite.

3.8.2 indUstRiAL toURism

Industrial tourism is emerging as a popular segment of the tourism market, with several regions and cities adopting such practices as part of large-scale industrial developments. Some of these cities include Nagoya, Rhone-Alps, Turin, Rotterdam, Amsterdam, Shanghai and Pennsylvania. Aside from creating employment and income, a comprehensive supply of company tours can help to improve the image and reputation of the regions/cities and industrial developments they are associated with.

In order to incorporate industrial tourism into the ANSIA, CCR recommends a jointly funded and developed visitor’s centre that provides information about all of the processing plants within the ANSIA, with an elevated rooftop platform to allow visitors to gain clear panoramic views of the ANSIA and port area, similar to the Woodside Visitor Centre situated on the Burrup Peninsula.

Given that a significant level of development is required to justify the implementation of successful industrial tourism initiatives, LandCorp will continue to work with DSD and further investigations will be undertaken once development of the ANSIA has commenced. Any such proposal will reflect the provisions of TPS7 and address matters including management of such a facility and public safety from the strategic industries of the ANSIA. LandCorp will address this further with stakeholders including Chevron, DPA and other users.

46

3.8.3 indUstRiAL pRecincts

3.8.3.1 Strategic Industry

The Scarborough LNG, which is currently under consideration, and the Macedon Domestic Gas Projects represent the core operational components of Stage 1B of the ANSIA, comprising facilities and infrastructure for the production and processing of LNG and domestic gas. Consistent with the approach for Wheatstone project, the Scarborough project shall be subject to an amendment to this Development Plan and future Scheme Amendment.

3.8.3.2 Future Industrial Area (FIA)

The FIA refers to the area that is not allocated to the Macedon and Scarborough facilities within Stage 1B. The FIA is to be developed as a multi-user industrial estate comprising a number of synergistic services and facilities with the core LNG industries. These will include hydrocarbon-related industries, such as urea, ammonia and ammonium nitrate plants, methanol plants, and refinery industry. The FIA is also proposed to include public utility infrastructure including electricity generation, water desalination and supply and waste water treatment that will service the ANSIA.

The proximity of the FIA area to the LNG industries provides the opportunity for development of industrial activities that directly benefit from their proximity to these industries as well as the proposed CUCA, port and MUAIC.

3.8.4 tRAnsient WoRkFoRce AccommodAtion

A second Transient Workforce Accommodation (TWA) site is proposed to be situated approximately 4 kilometres south-west from the FIA and 6 kilometres from the nearest gas production site. The second temporary TWA will provide accommodation for workers associated with the construction and development of infrastructure associated with the Scarborough project and future industries within the FIA, should the Wheatstone TWA reach capacity. As identified under the ANSIA Structure Plan, the camp will also accommodate casual workers that may be associated with contractors but not directly aligned with the proponent.

The second TWA camp is envisaged to be developed in stages, and has the capacity to accommodate between 3,000-5,000 construction workers at peak if necessary, however it may be utilised to accommodate workers associated with infrastructure construction such as the airport upgrade, power, roads etc, which may result in an additional 1,000-2,000 workers at peak construction times. It is anticipated that the construction personnel will work a fly-in, fly-out roster, commuting to and from the project area.

The second TWA is intended to act as an ‘overflow’ for the Wheatstone TWA, and is likely to be developed by the private sector where demand necessitates it. If required, the second TWA is to be constructed by future proponents within the ANSIA. However no development will be supported by LandCorp or approved by the Shire unless clarity of where the construction workforce associated with Stage 1B and 1C will

be housed. This will be defined through the Workforce Management Plan process required for each development and subdivision. It is emphasised that such accommodation is not supported within the Onslow townsite.

The second TWA has been identtified so as to limit the impact on Onslow, which is unable to provide the available land, housing and facilities. The TWA camp will likely be a self-contained development incorporating appropriate services, and recreational/entertainment facilities, and designed to enable the safe retention and protection of personnel during cyclonic events. A rehabilitation plan is required to accompany any future Development Application for the TWA, to the satisfaction of the Shire.

3.8.5 Finished gRoUnd LeVeLs

Further to the report undertaken by BG&E and given the topography of the Stage 1B and 1C areas, a number of areas may be subject to flooding. Proposed development that is outside the floodway is considered acceptable with respect to major flooding. However, in areas subject to flooding, “islands of development” are recommended, with a minimum finished ground level of RL5.0m, which is 0.5m above the 1 in 100 AEP (annual exceedance probability), to ensure adequate flood protection.

3.8.6 on-site And oFF-site bUFFeR ReqUiRements

Section 6.7 of the ANSIA Structure Plan describes the application and requirements of buffers within the ANSIA. Specifically the Structure Plan includes a general 3000m ‘Risk, Noise and Air Quality’ buffer around the Strategic Industrial Area and a standard 1000m ‘Land Use Sensitivity’ buffer around the Transient Workforce Accommodation sites.

The Structure Plan states that the buffer distances have been informed by the requirements of the EPA’s Guidance Statement No. 3 in reference to the potential and proposed industrial uses within the ANSIA and are deemed to meet the acceptable limits.

This Development Plan conforms to the general land use and therefore buffer requirements identified under the Structure Plan, however more detailed investigation into the buffer requirements can be addressed at Development Application stage.

3.8.7 LAndscApe And VisUAL impAct Assessment

Given the location of the ANSIA and the distances between it and the current Onslow Townsite, it is not anticipated that development of the ANSIA will have a significant visual impact for the residents of Onslow. Furthermore, as the specific land uses and developments have not been identified at this stage, it is difficult to gauge the impact the ANSIA will have on the visual amenity of Onslow. It is therefore expected that a more detailed visual impact assessment be completed by individual proponents, to the satisfaction of the Shire, at development application stage.

48

3.8.8 RecReAtionAL FAciLities

Given the arid climate in Onslow and the greater Pilbara Region, provision of open space and recreational facilities is somewhat constrained. Onslow hosts a range of recreational facilities, from sports ovals and basketball courts, to water playgrounds and community gardens. However, as the majority of construction workers will be housed within the TWA’s of the ANSIA, each TWA camp will need to incorporate recreational facilities into its design.

The second TWA associated with Stage 1B is anticipated to be developed the same as the Chevron TWA and include similar recreation and entertainment facilities. However, as no individual proponents have been identified at this stage.

3.8.9 Lighting And noise Assessment At the AshbURton RiVeR

Given that the specific land uses and exact siting and design of individual developments has not yet been identified, it is difficult to gauge the impacts of light and noise emissions from the ANSIA. It is therefore expected that a more detailed lighting and noise impact assessment and cumulative risk assessment be completed at Development Application stage, to the satisfaction of the Shire.

3.8.10 FiRe mAnAgement And emeRgency seRVices pLAn

It is expected that the second TWA village will be completely self-contained, similar to the Wheatstone TWA, and provide workers with their own water and power supplies, waste management, medical and fire services. Given that a WMP is not required at this stage, it is expected that matters pertaining to fire management and emergency services be addressed via a WMP at Development Application stage.

Fire and emergency services associated with the General Industry Areas (Stage 1C) are also to be addressed at subdivision and Development Application stage, given that the exact nature of the industries in the GIA as well as specific proponents have not yet been finalised.

3.9 EXISTING AND PROPOSED INFRASTRUCTURE

3.9.1 stAte pReFeRence FoR shARed seRVices

In planning the ANSIA and subsequent Onslow town site growth, the State has become increasingly aware of the benefits associated with shared services. Typically, most large-scale heavy industry proponents tend to generate their own power and water, constructing and servicing infrastructure for their own needs. In doing so, numerous economic, environmental and social benefits are lost.

49

For all future heavy industry proponents locating in the ANSIA, the State, through LandCorp and DSD will be investigating the possibility of creating a shared services integrated network in the ANSIA that can be extended to public use within and outside of the ANSIA. This is a complicated matter that remains in its infancy and LandCorp and DSD are investigating this further in order to fully understand and realize the applicability of a shared structure within the ANSIA.

It should also be noted that LandCorp is required to sign any application for developmwent/subdivision within Stage 1B (on behalf of the State) and shall only do so when satisfied that the proposal addresses the requirement for shared servicing.

3.9.2 AiRpoRt

3.9.2.1 Current Status

The Onslow airport consists of two gravel runways of 1600 metres and 990 metres in length. Use of the airport is restricted to Code 3 aircraft (Fokker 50), and is not suitable for large passenger aircraft. The main runway is limited to a takeoff mass of 20 tonnes due to the length and strength of the runway. Both runways are 30 metres wide, and were upgraded in 2002-2003 to raise their level and reduce the risk of flooding. Some work is still required to meet Civil Aviation Safety Authority standards.

3.9.2.2 Future Requirements

The existing Onslow Airport is planned to be

upgraded which will involve strengthening and widening of the runway pavement to accommodate passenger jet aircraft. An upgrade is required if large passenger aircraft are required to service the town, with peak demand expected to be during the construction phase of the ANSIA. The alignment of the runway is also to be modified to allow aircraft to take-off towards the Port in order to reduce the impacts from aircrafts on nearby residential areas.

3.9.3 WoRkFoRce AccommodAtion

3.9.3.1 Accommodation Requirements 2011-2016

According to current population growth forecasts, accommodation requirements for this period will be generated by the BHP Billiton Petroleum Macedon and Chevron Wheatstone projects, the expansion of the Onslow Salt operations, and the indirect and consequential population increase arising from these projects.

3.9.3.2 Construction Phase

Both BHP Billiton Petroleum and Chevron will house their construction workforce on their respective sites on the ANSIA. The proponents will provide the required supporting services, including accommodation, water supply, wastewater treatment, waste disposal, power and transport to and from the airport for their construction workforce.

In this regard, the proponent for the project is totally responsible for housing their own direct construction employees, along with their

50

contractors, sub-contractors and authorised visitors who have direct involvement with their respective proposals. All proponents will enter into an agreement with the Shire to reflect the WMP and the proponent’s responsibilities.

3.9.3.3 Ongoing Operation Phase

BHP Billiton Petroleum will house their estimated 10 operational employees within the Onslow town site. Chevron will house its estimated 300 initial operational employees permanently in the Onslow townsite, as a requirement of TPS7.

3.9.3.4 Accommodation Requirements 2017-2022

For planning purposes, it has been assumed that a similar approach to that proposed by Chevron for its Wheatstone project will be adopted by future projects (i.e. the proponents will house the construction workforce within the ANSIA.

3.9.4 onsLoW RoAd


Onslow Road was built in the 1980’s to service the Onslow community and Onslow Salt venture and at present the majority of the road has a relatively narrow seal width (6.2 metres generally) and shoulders that are unsealed.


The upgrading of Onslow road is planned to be undertaken in two stages:

• Interim Upgrade – A funding contribution has been negotiated with Chevron Australia Ltd to undertake some interim improvement works on Onslow Road to accommodate construction activities associated with the Macedon and Wheatstone projects. These improvements include:

• Sealing of shoulders for 79km (bothsides);

• Installtwowestboundandtwoeastboundovertaking opportunities;

• Reconstruct11kmofOnslowRoadthatis considered marginal;

• AsphalttheNorthWestCoastalHighway/Onslow Road intersection;

• AsphalttheOnslowRoad/BeadonCreekintersection;

• Applylinemarkingtothecentrelineandedges; and

• Provide lightingtoNorthWestCoastalHighway/Onslow Road intersection.

• Major Upgrade – Once the Macedon and Wheatstone projects are substantially complete a substantial upgrade/remediation of Onslow Road will be undertaken. As part of the SDA, Chevron has committed to providing a contribution towards these works, which will see the existing pavement of Onslow Road widened to 10 metres with a total seal width of 9 metres (two 3.5 metre carriageways with 1 metre sealed shoulders either side).

51

3.9.5 noRth West coAstAL highWAy


The North West Coastal Highway, together with the Brand Highway, forms a major freight route between Perth and the North West, and is also the main link between regional centres at Geraldton, Carnarvon, Karratha and Port Hedland. The demand for freight movements will increase with proposed industry expansions and new mining development in the Northern Gascoyne and Western Pilbara.


Main Roads is currently pursuing funding for an upgrade of North West Coastal Highway (NWCH) that will involve:

• Widening o f a 135 km sect ion and asignificant length of reconstruction/overlay, and provide for a total pavement width of 11 metres with a 9 metre seal (two 3.5 metre carriageways with 1 metre sealed shoulders either side); and

• Upgradeoffiveculvertsitestobridges–twoto the south of Onslow Road and three to the north.

Further to the above, LandCorp, through the development of Onslow is facilitating the coordinated development to cater for the proposed population increase resulting from the development of the ANSIA.

3.10 IMPLEMENTATION

3.10.1 timeLines And stAging

Development within the ANSIA is likely to be staged as identified in the ANSIA Structure Plan. Firstly, the access corridors are to be constructed with the development of the natural gas plants. It is anticipated that any costs associated with upgrading of the corridor to adequately service further development of the ANSIA will be apportioned between individual proponents, based on the scale and nature of the development.

As proposals occur, each individual development site will connect to the MUAIC via industrial collector roads. It is also expected that the individual sites will connect to infrastructure services, including water supply, sewerage and electricity.

LandCorp is currently investigating the feasibility of developing the GIA’s, which may act as a catalyst for development within Stage 1B. Land development within the GIA’s should be undertaken in a coordinated, staged manner, with staging of the GIA’s being developed based on market demand.

52

4. PLANNING MERIT

4.1 ORDERLY AND PROPER PLANNING

The proposed Development Plan represents the logical, orderly and proper development of the land that is consistent with both the current strategic vision prescribed by the ANSIA Structure Plan, which has been endorsed by the Shire and also the statutory objectives highlighted by LPS7 and proposed Scheme Amendment Nos. 17 and 18.

At the strategic level, the proposed Development Plan will facilitate achieving the objectives of the recently endorsed ANSIA Structure Plan, which highlights the site as being developed for both LNG and domestic gas production as well as related downstream industries. The site is also a logical extension of the existing Stage 1A site, which is currently occupied by Chevron for development of its Wheatstone facility.

From a statutory viewpoint, the Development Plan assists in achieving the objectives of the Scheme as per Appendix 11 of TPS7 in that it will promote regional development, provide a gas precinct to monetise gas fields in the Carnarvon Basin and promote more diverse sources of domestic gas.

In addition the Development Plan ensures that future stages of the ANSIA can easily be integrated and developed in an orderly and proper manner in accordance with the ANSIA Structure Plan.

4.2 DEMAND FOR PROPOSED DEVELOPMENT

Following significant gas discoveries between 2000 and 2004, the Premier of Western Australia and Minister for State Development endorsed the commencement of investigations to create the ANSIA to cater for proposed LNG and domestic gas processing, as well as related downstream processing opportunities. The Ashburton North site is large enough to accommodate major LNG developments and other prospective industry.

In 2008, Colin Barnett, Premier of WA stated “In choosing to develop the site, the Government has taken into account community interests and the suggestions of the prospective users of the new precinct. Ashburton North is further from the town of Onslow than the existing Onslow industrial area and has ample room for future development.

It has suitable access to the coast for LNG developments and will be able to accommodate a mix of future industrial activities.”

BHP and Chevron then progressed with environmental assessments for their Wheatstone and Macedon sites throughout 2009 and upon clearance for any statutory constraints, progressed amendments to the Shire of Ashburton TPS7, creating a “Strategic Industry” zone to establish the statutory base for the ANSIA. The Shire of Ashburton also prepared the Onslow Townsite Strategy (OTS), giving further weight to the development of the ANSIA.

53

Chevron and BHP are now progressing with their Wheatstone and Macedon developments (respectively), while ExxonMobil are continuing their feasibility investigations. BHP’s Macedon approval was based on the understanding that the rezoning would be undertaken at a later date as part of the ANSIA Stage 1B planning approvals process. The Premier, in his address of 2008 stated “both of these would provide a much-needed boost to WA’s future energy security.”

In 2009-2010, ARUP was commissioned by LandCorp and the Department of State Development to undertake a Concept Design Planning Study, focusing on the industry estate and infrastructure corridors within Stage 1. ARUP stated in its report that “Although not directly related in gas processing, related industries are those that share strong links with the core industries, either through:

• Direct input-output linkages with core industries;

• Demand for products and services derived from the presence of core industries and the resultant concentration of industrial investment; or

• Intermediate (or even nonexistent) input-output linkages with core industries and/or processing activities that create similar externalities or require similar enabling infrastructure.

Table 7 details the proposed related industry activity that may potentially locate within the ANSIA and the linkage between core and related industry.Support industries in the ANSIA can be categorised as follows:

• Those industries that provide essential services (as opposed to any actual process) to core and related industries - typified by maintenance, engineering and fabrication industries; and

• Those industries that support the extractive industries located within proximity to the ANSIA – both offshore and onshore.

54

A number of opportunity areas exist for industrial processing and other related opportunities in the ANSIA as a result of the proposed development of the projects three anchor gas processing proponents. These can be broken into three categories, those that have the potential to be realised in the short term, those in the medium term, and those in the long term.

In the short term (5-15 years) opportunity areas can be broken into four main areas:

1. Opportuni t ies for producing products from downstream chemical processing of the natural gas (e.g. Ammonia; Urea; Ammonium nitrate; Methanol; and Ethylene and Propylene) and non-gas processing (Sodium cyanide; and Chlor-Alkali);

2. Opportunities for producing value added products from by-products of the LNG processing (e.g. elemental sulfur);

3. Opportunities for utility synergies (e.g. common water supply plant) and utilisation of by-products from these (e.g. salt from the water desalination units); and

4. Serv ice synerg ies , such as common engineering services.

In the medium term (15-40 years) some of the opportunities will include:

• Opportunities for downstream processing industries not currently viable (e.g. Gas to liquids; and Plastics and pharmaceuticals); and

• Opportunities for waste treatment utility synergies (e.g. industrial water recycling plant).

In the long term (40+ years) other possible opportunities are likely to emerge, such as:

• Geosequestration of CO2 in the depleted gas fields from conventional processing industries in the ANSIA; and

• New processing industries not yet developed (e.g. biofuels from Algae).”

4.3 ENVIRONMENTAL IMPACT ASSESSMENT

The land subject to this Development Plan has been assessed in terms of the environmental constraints in the areas of flora, fauna and acid sulfate soils. The land has been the subject of a broad geotechnical assessment and hydrological study from which a Local Water Management Strategy has been prepared.

The Development Plan and Scheme Amendments identify those areas in Stage 1B and 1C that have been deemed as suitable for development as a result of these assessments.

The Development Plan requires eventual proponents within Stage 1B to refer such proposals to the EPA for assessment in accordance with s38 of the Environmental Protection Act 1986 prior to lodging a Development Application with the Shire.

55


56

5. CONCLUSION

This Development Plan has been prepared in order to facilitate the orderly future subdivision, land use and development of portions of Stages 1B and 1C of the Ashburton North Strategic Industrial Area (ANSIA).

The Development Plan will complete the rezoning of the area comprising the Macedon Project, an industrial area for the purpose of downstream gas processing industries, a second Transient Workforce Accommodation (TWA) precinct and a general industrial area to support the ANSIA and Onslow Townsite.

The Development Plan and this supporting report demonstrate how the proposed development is in accordance with State and Local Government vision for the site, in particular the Draft ANSIA Structure Plan and the objectives of the Shire of Ashburton Town Planning Scheme No. 7 and proposed Amendments No. 17 and 18.

Based on the consistency of the Development Plan with the agreed vision for the site and that the design represents the optimal development outcome for the site, it is requested that the Shire and WAPC approve the Development Plan at its earliest convenience to enable subdivision and development to occur.

Basis for Development Plan

1. PreambleThe Development Plan has been prepared for DSD as lead agency and LandCorp as the Estate Manager. The basis for the Development lies within the ANSIA Industrial Ecology Strategy prepared by CCR. Industrial Ecology refers to smart(er) design and operation of industrial estates from an economic, environmental and community perspective by optimising resource efficiencies through industrial collaboration in order to ensure the long term viability and sustainability of the estate.

The intention of the Development Plan is to guide future proponents and development within the ANSIA so as to realise the resource efficiencies outlined in the Industrial Ecology Strategy. The Industrial Ecology Strategy builds upon the technical studies undertaken and identifies preferred locations for a range of downstream industries, based on best-practice industrial ecology principles, to establish a sustainable major hydocarbon processing estate.

The Industrial Ecology Strategy is to be used by DSD and LandCorp to guide future planning in the ANSIA and should a proponent propose to locate a land use in a location not identified on the Development Plan, the consent of LandCorp and DSD is required.

2. Vision/PurposeThe objective of the Development Plan is to create a major hydrocarbon processing hub of State and National significance, fostering a secure environment for major gas processing industries, surrounded by infrastructure, services and related downstream industries to deliver maximum benefit from the resources to the community, at both micro and macro levels, in a sustainable manner.

To achieve the vision of a sustainable hydrocarbon processing precinct at the ANSIA, planning for the estate will aim to optimise the clustering of hydrocarbon processing and related downstream activities to achieve a high level of functionality and sustainability. Design will be built on flexibility and spatial, physical and operational foundations and the utilisation of emerging best-practice industrial ecology principles to maximise opportunities to adapt to meet future changes in industry needs and policy settings.

Facilitation and management of the estate in this manner will focus on cross flow of product and feedstock, encouraging energy and water efficiency and equitable access to export and import facilities. Development of the ANSIA will assist in the delivery of social and economic benefits to the wider Onslow community, region and the State and ensure the long term viability and sustainability of the ANSIA and Onslow.

3. Western Multi-User Access & Infrastructure Corridor (MUAIC)A second MUAIC is proposed on the western side of the ANSIA and is intended to provide a critical transport link within the ANSIA, TWA’s, GIA’s, CUCA and Port, whilst minimising the risk of compromising Onslow Salt’s operations. The second MUAIC will also allow for efficient transportation of materials throughout the ANSIA and CUCA/Port.• All major communication, freight and logistics infrastructure development, where possible,

are to be contained within the western or eastern MUAIC.• Access to the GIA’s and the TWA’s is to be from the MUAIC.

4. Common User Coastal Area (CUCA)The CUCA comes under the jurisdiction of the Dampier Port Authority (DPA). The DPA is responsible for preparing a separate Port of Ashburton Development Plan and a Port of Ashburton Infrastructure and Land Use Master Plan to guide development within this area.The marine facilities identified in the Development Plan are indicative only and are based on the long term realisation of the ANSIA, based on the Industrial Ecology Strategy. The final location of these facilities will be subject to detailed planning, which is being undertaken by the Dampier Port Authority.• The CUCA is to be designed and implemented in a way that facilitates and allows for

future development within the ANSIA.• The ongoing use and operation of the CUCA and associated Port facilities is not to be

compromised by any development within the ANSIA.

• Approval from the DPA is required for all development within the CUCA precinct.

5. Transient Workforce Accommodation (TWA)A second TWA camp is proposed under the LandCorp ANSIA Industrial Development Plan and will accommodate the construction workforce associated with the ANSIA. The second TWA is intended to accommodate approximately 5,000 construction staff at peak, and may be utilised to accommodate staff associated with infrastructure construction such as the airport upgrade, power, roads etc, which may result in an additional 1,000-2,000 workers at peak construction times. The second TWA camp is temporary and will limit the impact on Onslow during the construction phase, as Onslow is unable to provide the available land, housing and facilities.

6. Ammonia ClusterThe key anchor tenant for the ammonia cluster, and essential to the development of the non-LNG component of the industrial estate, is an export ammonia plant, which as well as exporting ammonia, provides ammonia feedstock (and CO2) for a number of other plants including the urea and ammonium nitrate plant/s. Attracting a large single ammonia producer, who can also export ammonia as an anchor tenant will optimise the chances of attracting subsequent downstream ammonia processing proponents. In doing so, the benefits of the ammonia cluster can be realised.

7. Gas to Liquids (GTL) ClusterThe GTL cluster has been initially planned with three areas, one to allow a smaller gas to liquids plant (such as a methanol plant), one large area for a large gas to heavy liquid fuels plant, and a power and water supply precinct. It is likely that due to economies of scale the whole of this area (apart from the utilities area) could be taken by a single GTL plant.

8. Utilities ClusterIn accordance with Condition 12 of the ANSIA Structure Plan, the development of utility synergies within the ‘Strategic Industry’ zone is recommended whereby larger common utilities are developed and shared by a number of industries rather than each having its own individual smaller plants and associated service lines. This approach will lead to economies and efficiencies of scale in the utility plants themselves as well as reduced costs and increased efficiencies from the use of larger, common service pipelines. The co-location of larger desalination and power plants together allows (physically and economically) the option of thermal desalination using the low-grade waste heat from the combined cycle power plant as well as nearby industry.
