Attention: Mr Ben Williams

Dear Mr Williams

Re: Development Application 340/V005/2020 Grain Export Facility

Cresco Road, Wallaroo

On behalf of T-Ports Pty Ltd, we refer to our discussions regarding the above-mentioned Development Application. The application has been submitted pursuant to Section 131 of the Planning, Development and Infrastructure Act, 2016.

As you are aware, since the application was lodged, requests for additional information have been received from the Environment Protection Authority (‘EPA’) and the Coast Protection Board (‘CPB’). These requests have been responded to, and in the course of preparing these responses, the proposal plans and some of the technical reports submitted with the original application have been updated.

In addition, feedback has been received from the Department of Infrastructure and Transport (‘DIT’) in respect of the informal response to them.

Finally, there have been some requests for clarification from Planning and Land Use Services (‘PLUS’).

Updated Documentation

Having regard to the proposed development needing to undergo public notification and to the changes to the proposal plans and technical documents, we have taken the opportunity to update the Planning Report and accompanying appendices, which include the proposal plan and technical reports.

Please find enclosed with this correspondence an updated Planning Report, which is provided in substitution of that previously submitted.

Attorney General’s Department – Planning and Land Use Services GPO Box 1815 ADELAIDE SA 5001

50510LET15 2

The Planning Report has been recompiled, and where updates have been made to the plans and appendices, they have been updated. The report is now in a form that it provides a suitable package for the purposes of public notification of the application.

For clarity, the following amendments have been made to the appendices to the planning report:

• Appendix A: Certificates of Title Register Searches – No changes;

• Appendix B: Locality Plans and Allotment Identification Plan – Additional locality plan showing relative location of transhipment points added;

• Appendix C: Site Plans – New appendix providing base plans for each of the sites added;

• Appendix D: Triaxial Plans – No changes;

• Appendix E: WGA Plans – Updated proposal plans provided;

• Appendix F: MPS Projects Plans – Updated proposal plans provided;

• Appendix G: Stormwater Management Plan – No changes;

• Appendix H: Acoustic Report – Updated report provided;

• Appendix I: Air Quality Report – Updated report provided;

• Appendix J: Traffic and Parking Assessment – No changes;

• Appendix K: Terrestrial Ecological Assessment – No changes;

• Appendix L: Marine Ecological Assessment – No changes;

• Appendix M: Coastal Process Modelling Assessment – Updated report provided; and

• Appendix N: Core Placement Plume Dispersion Modelling Assessment – Updated report provided.

Consequential changes have also been made to the Planning Report itself. The changes do not change the essential nature of the development, its capacity or throughput or fundamentally alter the manner in which it is either proposed to be constructed, or to operate.

PLUS Clarification

By email dated 28 October 2020 and during our subsequent discussions, PLUS had requested clarification on a number of items in respect of the proposal.

50510LET15 3

We respond to each of those items below.

1. Document the anticipated construction trip generation and impacts on the surrounding road network. Specifically, please indicate the anticipated truck and barge movements for the construction of the breakwater. Please confirm the likely route vehicles will travel to the site for the delivery of the breakwater materials.

The construction methodology has been further detailed in the responses provided to the EPA and CPB.

In respect of construction traffic movements, we can confirm that the majority of materials for the causeway will be sourced from an existing quarry at Poona, south of the subject site. The route for bringing materials to the site will include the Spencer Highway and Cresco Road. This route will avoid a need for trucks to transit through the Wallaroo township.

It is anticipated than construction traffic between the quarry and the site will involve up to 120 movements per day.

The construction of the causeway will occur utilising land-based construction methods and will not require a barge or other significant marine operations.

2. Submit a Data Report for the proposed terrestrial and marine vegetation clearance which clarifies the categorisation of the vegetation.

A data report in respect of the marine vegetation clearance is currently being finalised and will be provided once complete. The clearance of marine vegetation represents the overwhelming majority of vegetation clearance associated with the development with only a very small area of degraded terrestrial vegetation required to be cleared.

It is noted that the CPB agreed to defer further consideration of the clearance of terrestrial vegetation until approval has been granted, when an application will be made in accordance with the requirements under the Native Vegetation Act, 1991.

It is respectfully requested that the finalisation of the data report should not delay the public notification of the application.

3. Confirm the where the barge will be docked, repaired and fuelled.

The transhipment vessel will primarily be moored at the Lucky Bay Common User Export facility.

Minor maintenance and bunkering may occur while the vessel is moored at the proposed facility; however primary maintenance will still occur at Lucky Bay.

Significant maintenance will occur in a licensed facility.

50510LET15 4

4. Detail the process involved in confirming the transhipment location and associated exclusion zone. Given this is a pivotal element of the proposal, confirmation of this location is required in order to determine if a referral is required to a relevant State Agencies. Of equal importance is a defined transhipment location prior to public notification so that the public can consider a resolved proposal. Can you please also provide a map of the identified transhipment location and exclusion zone in context of the proposed wharf and landside infrastructure.

The location of the transhipment point candidates was determined by a desktop data review. Subsequently, further investigations including a benthic ecological investigation was undertaken to determine the suitability of sites.

The benthic ecological assessment has resulted in one (1) of the three (3) transhipment point candidates being excluded.

In a similar manner to Lucky Bay, the application is sought on the basis of two (2) identified transhipment points. This provides a level of redundancy in the event that one (1) ultimately becomes unsuitable on operational grounds.

Additional plans have now been prepared and is included in the updated planning report enclosed which detail the location of the transhipment points in the context of the causeway and terrestrial facilities.

5. The MPS conceptual plans appear to identify a mooring facility which is inconsistent with the WGA plans. Can you please confirm which mooring arrangement will be progressed and update any necessary plans to rectify the inconsistency?

As highlighted above, the updated planning report enclosed contains a revised plan set which resolves the inconsistencies identified in the previous plans.

6. Submit a draft Construction Environmental Management Plan for assessment.

A draft CEMP prepared by Lucas Total Contract Solutions (in respect of the causeway construction) and a draft CEMP by Allied (in respect of the silo construction) are enclosed with this correspondence.

7. Confirm the relationship between the proposed Crown application and the bulk handling application where Council will be the relevant authority. Please confirm the status of this application and the anticipated timing for public notification (if required).

Development Application 340/427/2020 for a Bulk Storage and Handling Facility was granted Planning Consent by the Copper Coast Council on 4 May 2021.

This application was assessed as a Category 1 application, and consequently did not require any public notification.

For reference, a copy of the Decision Notification Form issued by Copper Coast Council is enclosed with this correspondence.

50510LET15 5

DIT Clarification

By email dated 11 June 2021, DIT provided feedback in respect of an information referral to the proposal.

The issues raised are similar issues to those that T-Ports has addressed at Lucky Bay, which are primarily addressed via documentation as part of the Port Operation Agreement required under the Harbours and Navigation Act 1993.

Having regard to the nature of the queries, T-Ports intends, via its case manager for the project, to organise a meeting with relevant DIT staff to further discuss the maritime issued associated with the proposal.

1. Actual location of Transhipment points are not provided, only circles on a map provided.

The location of the transhipment point candidates is detailed in the updated Planning Report enclosed and in the Marine Ecological Report forming Appendix L to the updated Planning Report.

2. Size of OGVs being loaded not detailed.

OGVs are anticipated to be up to Panamax in size.

3. Traffic impact assessment and planning (marine) not provided.

T-Ports will engage further with DIT in respect of marine vessel traffic management. It is anticipated that a Vessel Traffic Management Plan will form a component of documentation under the Port Rules requires as part of the Port Operating Agreement.

4. Evidence of the suitability and safety of operational at the transhipment points (simulation/ modelling) needs to be provided.

T-Ports will engage further with DIT is respect of their requirements for this item.

5. Recommend the latest hydrographic survey be submitted (Flinders Ports 2020) for assessment.

T-Ports will seek to obtain and provide the latest hydrographic survey to DIT.

6. Charted bottom features (4.7m) in the possible route to transhipment points is to be further surveyed to assess if a navigation mark is required. (berth to harbor limits as a minimum).

T-Ports would be accepting of a condition in respect of further survey being collected prior to operations commencing.

50510LET15 6

7. Operational area (Future Port) will boarder an existing operational port and transhipment points are in the vicinity of existing channel and pilot boarding grounds and existing passenger ferry route. Recommend assessment be made into the a vessel traffic management system be used to manage decision making process of managing marine traffic in and around Wallaroo Harbor and spencer Gulf Deepwater route.

T-Ports would be accepting of a requirement for such investigations to occur during the negotiation of the Port Operating Agreement.

8. Berthing infrastructure is to be marked with navigation aids and/or lights to the satisfaction of marine services.

T-Ports would be accepting of a condition in respect of requirements for aids to navigation to be further addressed via the Port Operating Agreement.

Given the technical and operational nature of the feedback from DIT, it is respectfully requested that the further consideration and resolution of these issues should not delay the public notification.

Closure

We trust the revised information and clarification will enable the public notification of the application to proceed as soon as possible.

If you require anything further, please do not hesitate to contact the writer.

1.0 INTRODUCTION

MasterPlan SA Pty Ltd has been engaged by T-Ports Pty Ltd (‘T-Ports’) to prepare a development application for the development of a Grain Export Facility on a site located at 133-145 Chatfield Road, Wallaroo.

T-Ports, through a related entity Inheritance Capital Asset Management (‘ICAM’), have exercised theiroption in respect of Allotment 1 and Allotment 2 Chatfield Road and have purchased this land from theDistrict Council of Copper Coast (‘DCCC’) to facilitate the progression of the project.

Land on which the causeway, conveyor and wharf infrastructure is constructed is in the ownership of the Minister for Environment and the Minister for Infrastructure and Transport. The coastal reserve is under the care and control of the District Council of Copper Coast. T-Ports has entered into discussions with the Department of Environment and Water (‘DEW’), the Department of Infrastructure and Transport (‘DIT’) and DCCC in respect of obtaining appropriate tenure over these areas.

T-Ports have secured Crown sponsorship of the proposed development from DIT for the application to belodged with, and assessed by, the State Commission Assessment Panel (SCAP), as a Crown Developmentunder Section 131 of the Planning, Development, and Infrastructure Act 2016.

The proposed Grain Export Facility is to be associated with a Bulk Handling and Storage Facility located further south of the subject site that is the subject of a separate application lodged with DCCC under the Development Act 1993.

This report contains the following information:

• a description of the subject land and locality;

• a description of the proposed development; and

• an assessment of the proposal against the relevant provisions of the Development Plan.

This report has been prepared in conjunction with technical reports prepared by the project team, which provide a detailed assessment of the anticipated impacts and requisite management techniques for:

• air quality;

• acoustic performance;

• marine ecological assessment;

• costal processes assessment;

• sediment plume modelling;

• stormwater management; and

• traffic management.

2 50510REP01

The technical reports for traffic management, acoustic impacts and air quality integrate the assessment and findings for both the proposed Grain Export Facility and the Bulk Handling and Storage Facility that is subject to a separate application.

This approach has been adopted as the potential impacts of the proposal are cumulative and cannot be modelled independently. Only those aspects of the technical reports which related to the proposed Grain Export Facility as described in this report are relevant to the assessment of this application.

This report concludes that on balance, the location of the development, the nature of the proposal and the anticipated impacts when considered in its totality, warrant Development Approval being granted.

2.0 SUBJECT SITE

The land comprising the subject site is formally identified as

• Allotment 1, Deposited Plan 81455, Hundred of Wallaroo (CT Volume 6039 Folio 557);



• Section 3062, Hundred of Wallaroo (CR Volume 5745 Folio 943); and

• Section 1693, Hundred of Wallaroo (CR Volume 5755 Folio 951).

A copy of Certificate of Title Register Searches for the subject site is contained in Attachment A.

The Certificate of Title Register Search confirms that there are no easements, encumbrances or otherwise that would prevent the construction of the proposal.

The location of each allotment is shown on the attached Locality Plan, Locality Plan Enlargement and Allotment Identification Plan in Attachment B which also detail the zoning of the locality.

Site plans showing the location of the Transhipment Points, the Silo and Causeway Sites and the related Bunker Site (for which approval is being sought via a separate application to the District Council of Copper Coast) are attached in Attachment C.

The subject site consists of both terrestrial and marine environments and the proposal extends over the Cresco Road reserve. The various components which make up the subject site are described under the following subheadings.

2.1 Terrestrial – Silo Site

The proposed silo site is to be located on Lot 1 and 2 which has a total area of 4.03 hectares. The site has two road frontages, a north-western primary frontage to Chatfield Terrace of 209 metres and a south-western frontage to Cresco Road of 148.5 metres.

3 50510REP01

Vehicle access to the site is currently gained via a crossover located at the northern extent of the Chatfield Terrace frontage.

The is generally flat and was previously used as a Council depot. A demolition application was recently approved over the site as such the site is to be cleared of built form with the exception of a workshop located at the intersection of Chatfield Terrace and Cresco Road which has been retained as a component of the proposed development.

There are existing overhead powerlines which run along Chatfield Terrace past the subject site, along the southern frontage to Cresco Road and along the south-eastern boundary.

The following photographs illustrate the condition of the silo site. Please note that the site has been further cleared since the photographs were taken.

Photo 1: Silo site looking west from eastern corner of site.

Photo 2: Silo site looking north from southern corner.

4 50510REP01

Photo 3: Existing access to Chatfield Terrace.

2.2 Terrestrial – Conveyor and Wharf

The proposed conveyor belt will extend from the silo site in a north-western direction over Chatfield Terrace and onto Section 3062 and 1693. This portion of the site sits between Chatfield Terrace and the coast forming the coastal reserve.

Informal vehicle access is currently provided to the site from Chatfield Terrace with various informal vehicle tracks and parking areas on the site. The site is used principally for car parking, coastal recreation purposes and the disposal of stormwater to the marine environment.

Section 1693 is generally flat and devoid of vegetation with Section 3062 comprising a scattering of vegetation and dune/cliff to the coast.

The conveyor belt transitions to the proposed wharf within Section 3062.

The following photographs illustrate the current condition of the causeway and wharf site.

Photo 4: Existing Coastal Reserve looking north-east to silo site, showing informal parking area.

Photo 5: Looking north along Coastal Reserve with Chatfield Terrace and silo site to right.

Photo 6: Looking north-west at position of causeway.

6 50510REP01

2.3 Marine – Conveyor and Wharf

The proposed conveyor belt and wharf will continue to extend from Section 3062 in a north-western direction into the coastal waters of Lot 30 for a distance of approximately 500 metres. No vehicle access to Lot 30 is currently provided as the site is in the marine environment.

2.4 Marine – Transhipment Point

Three transhipment point candidates were identified for assessment located to the west of the silo and causeway site. The centre of the closest candidate is located approximately 9.0 kilometres (5.0 nautical miles) from the causeway, whilst the centres of the other two candidates are located approximately 12 kilometres (6.5 nautical miles) from the causeway.

Transhipment Point Candidate 1:

• Latitude -33.894050; and

• Longitude 137.476927.



• Longitude 137.476927.



• Longitude 137.507588.

Following benthic ecological assessment, Transhipment Point Candidate 3 was deemed to be more sensitive, with a higher density of seagrass. Transhipment Point Candidate 3 has therefore been excluded from further consideration.

The application is therefore proceeding on the basis of Transhipment Point Candidate 1 and Transhipment Point Candidate 2, and development approval is sought to use both. The selected transhipment point for operational purposes will be determined following further input from key stakeholders, most particularly the Department for Infrastructure and Transport (‘DIT’).

It is noted that the transhipment point does not require the construction of any infrastructure to support its operation.

7 50510REP01

3.0 LOCALITY

The site is located at the western extent of the Wallaroo township. The silo site is located in the Bulk Handling Zone of the Copper Coast Council Development Plan and sits adjacent to allotments located in the same zone to the north-east, south-east and south-west.

The terrestrial conveyor and wharf site to the north-west is located within the Coastal Open Space Zone of the Development Plan with the marine portion of the subject site located within the Coastal Waters and Offshore Island Zone of the Planning and Design Code.

Allotments directly east, south, and south of the site contain bulk handling and storage facilities in the form of silos and bunker storage units. Located south-west of the site, on the opposite side of Cresco Road, is a fertiliser operation.

The nearest sensitive receptors are dwellings located approximately 300 metres north-east of the silo site. These dwellings are located within the Residential Zone. The eight existing Viterra silos adjacent to the site are located closer to and setback approximately 230 metres from these dwellings.

The character of the locality is typical of that of bulk handling and storage areas located in the vicinity of the coast and on the outskirts of a township, with a mix of costal reserves, bulk handling and storage facilities and residential development, typically with some degree of separation from the bulk handing facilities.

The level of amenity in the locality is low to moderate, with existing silos and export facilities being the dominant visual elements. The level of amenity is impacted by the existing bulk handing facilities through their impact on the visual environment, and also by air quality, acoustic and traffic impacts.

The subject site is shown within the context of the locality on the enclosed Locality Plan and Locality Plan Enlargement provided at Attachment B.

16 50510REP01

In support of the proposed development, the following technical reports have been prepared and are provided:

• a Stormwater Management Plan prepared by Triaxial (Attachment G);

• an Acoustic Assessment prepared by Sonus (Attachment H);

• an Air Quality Assessment prepared by SLR (Attachment I);

• a Traffic and Parking Assessment prepared by Cirqa (Attachment J);

• a Terrestrial Ecological Assessment prepared by Larry Bebbington (Attachment K);

• a Marine Ecological Assessment prepared by J Diversity Pty Ltd (Attachment L);

• a Coastal Process Modelling Report prepared by Cardno (Attachment M); and

• Core Placement Plume Dispersion Modelling prepared by Cardno (Attachment N).

As highlighted previously, the acoustic, air quality and traffic reports integrate the assessment and findings for both the proposed Grain Export Facility and the Bulk Handling and Storage Facility that is subject to a separate application to DCCC.

The key components of the proposal are discussed in detail under the relevant subheadings below.

4.1 Silos

The proposed development comprises of two silos with a total height of 38 metres. The silos have a combined capacity of 22,000 tonnes. The metal tower associated with the silos has a total height of 48.7 metres above ground level.

Two smaller silos adjacent to the metal tower have a combined capacity of 500 tonnes giving the site a total capacity of 22,500 tonnes.

The proposed silos and tower are illustrated on the renders and elevations prepared by Triaxial and MPS Projects at Attachment D and Attachment F, respectively.

The silo storage will include ancillary facilities including employee amenities, parking and manoeuvring areas and landscaping.

Grain will be delivered to the harbour loading facility from either the T-Ports bunker storage, directly from farms or from other storage facilities.

17 50510REP01

4.2 Conveyor, Wharf and Breakwater

From the silos, a conveying system will extend in a north westerly direction across Chatfield Terrace and along a rock groyne structure extending into the water. At the end of the rock groyne structure will be mooring facilities for a low-draught self-propelled barge.

The conveying system will be located over Chatfield Terrace in such a manner as to ensure that suitable vehicle access, including for commercial vehicles remains available.

The conveying system will allow for the loading of the barges and has been designed to minimise the amount of infrastructure located in the coastal reserve areas. Other than the conveying system and suitable access arrangements, it is not anticipated that other operations will occur in the terrestrial allotments located within the coastal reserve.

Three transhipment point candidates were identified for assessment located to the west of the silo and causeway site. The centre of the closest candidate is located approximately 9.0 kilometres (5.0 nautical miles) from the causeway, whilst the centres of the other two candidates are located approximately 12 kilometres (6.5 nautical miles) from the causeway.



• Longitude 137.476927.



• Longitude 137.476927.



• Longitude 137.507588.

Following benthic ecological assessment, Transhipment Point Candidate 3 was deemed to be more sensitive, with a higher density of seagrass. Transhipment Point Candidate 3 has therefore been excluded from further consideration.

The application is therefore proceeding on the basis of Transhipment Point Candidate 1 and Transhipment Point Candidate 2, and development approval is sought to use both. The selected transhipment point for operational purposes will be determined following further input from key stakeholders, most particularly the Department for Infrastructure and Transport (‘DIT’).

It is noted that the transhipment point does not require the construction of any infrastructure to support its operation.

18 50510REP01

4.3 Operations

The proposed facility will have a throughput of a maximum of 500,000 tonnes of grain per annum. The proposal includes silo storage of approximately 20,500 tonnes, located on the land on the corner of Chatfield Terrace and Cresco Road.

The facility will receive grain predominantly during harvest season from October to January but will also receive grain at other times of the year when it is brought in from other storages and on-farm storage.

Export will occur throughout the year, but will typically be focussed on the months from December to May, when approximately one vessel per three-week period will be leaded.

The employment at the facility will be variable across the year, with a peak during the harvest and export seasons.

Typical employment numbers are anticipated to be peak at between 25 and 35, broken down, as follows:

• Harbour Loading Facility 10-15; and

• Barging Operations 15-20.

If the bunker facility is included (subject to a separate application), peak employment will increase by a further 20-25.

Construction employment is anticipated to peak at approximately 120 persons directly, with construction extending over a 9 to 12-month period. Indirect employment including in quarrying and fabrication would result in up to an additional 80 jobs during the construction, however, it is noted that only a portion of these will be local.

4.4 Heavy Vehicle Movements

Heavy vehicles will tram grain from the bulk handling and storage facility located south of Magazine Road to the site via Cresco Road. The heavy vehicles will enter the site from Cresco Road and circulate around to the intake building where the grain will be collected and stored in one of the two silos.

The heavy vehicles will then circulate back to the Cresco Road crossover and return to the bulk handling and storage facility for reloading.

In the order of 592 Semi-Trailer movements (in the order of 296 inbound and 296 outbound) would be associated with the tramming of up to 8,000 tonnes of grain per day at peak times.

4.5 Staff Access and Parking

The site’s light vehicle access will be associated with staff and visitor movements only at the proposed crossover on the site’s north-western boundary from Chatfield Terrace. The crossover provides access to a 16-space carpark for staff and visitors.

19 50510REP01

The access has been designed to facilitate simultaneous B99 design vehicle movements to/from Cresco Road.

4.6 Stormwater Management

Details regarding the stormwater management techniques for the proposal are contained in the Stormwater Management Plan prepared by Triaxial at Attachment G.

The proposed stormwater management strategy includes:

• The finished floor levels (FFL) are above the 1.0 per cent AEP (100-yr ARI) ponding level on siteand are higher than existing road levels. Proposed FFLs are:

- Main Tower = 7.10 metres AHD- Pump House = 7.35 metres AHD- Lab & Office = 7.20 metres AHD- MCC Room = 7.35 metres AHD- Silos = 9.85 metres AHD- Intake Building = 10.75 metres AHD

• It is proposed to have three (3) infiltration/conveyor swales to suit the site layout and proposedsite grading. Swale properties are as follows:

SWALES TOP WIDTH (M)

BOTTOM WIDTH (M)

MAX. DEPTH (M)

20% AEP PONDING VOLUME

(M3)

1% AEP WATER LEVEL

(M AHD)

OUTLETΦ

(MM)

1 4.5 1.5 0.375 475.2 6.28 375

2 4 1 0.375 38.8 7.20 375

3 7 1 0.75 51.1 6.27 375

• The maximum side slope for each swale is 1V:4H, with minimum longitudinal grade of0.2 per cent. Flatter longitudinal grade was proposed to allow infiltration of 20 per cent AEPrunoff along the swale base.

• Stormwater in excess of the 20 per cent AEP will be temporarily detained on site.

• Site outlet pipe is a 375-millimetre diameter marine grade reinforced concrete pipe, to dischargeto the existing grated inlet pit in the road verge.

• The proposed treatment train for the site is via swales and site infiltration of first flush/veryfrequent storm event runoff. Regular maintenance of swales is recommended to ensure efficiencyfor pollution removal and stormwater conveyance.

20 50510REP01

4.7 Construction Material Staging Area

It is proposed to utilise Section 1693 for a construction material staging area whilst the wharf structure is under construction. Locally sourced rock will be unloaded at the site which has previously been cleared of vegetation.

The staging area is approximately 200 by 50 metres providing a total area of 10,000 square metres. The staging area is to be utilised on a temporary basis whilst construction is underway. The staging area will be cleared post construction.

5.0 PROCEDURAL MATTERS

At the time of lodgement of the application, the sites are located in zones as follows.

The terrestrial facilities proposed are located in the Bulk Handling Zone and the Coastal Open Space Zone of the Copper Coast (DC) Development Plan – Consolidated 23 May 2019.

The breakwaters and harbour are located partially in the Coastal Open Space Zone of the Copper Coast (DC) Development Plan – Consolidated 23 May 2019 and partially in Coastal Waters and Offshore Islands Zone of the Planning and Design Code – Version 2.

The marine transhipment points are located in Coastal Waters and Offshore Islands Zone of the Planning and Design Code – Version 2.

6.0 ASSESSMENT

6.1 Planning and Design Code

The transhipment points along with a portion of the breakwaters and harbour are located Coastal Waters and Offshore Islands Zone of the Planning and Design Code. This section provides an assessment of the most relevant provisions of the Planning and Design Code.

6.1.1 Coastal Waters and Offshore Islands Zone

The Desired Outcomes (DO) of the zone are as follows:

DO 1 Protection and enhancement of the natural marine and coastal environment and recognition of it as an important ecological, commercial, tourism and recreational resource and passage for safe watercraft navigation.

DO 2 Small-scale, low -impact development for the purpose of conservation, navigation, science, recreation, tourism, aquaculture or carbon storage.

21 50510REP01

The following Performance Outcomes (PO) are considered the most relevant to the assessment of the application:

PO 1.1 Small-scale, low-impact development for the purpose of conservation, navigation, science, recreation, tourism or aquaculture.

PO 3.1 Development is undertaken in a manner which minimises the potential for harm to the marine and coastal environment or to fisheries and aquaculture, including harm arising from actions that introduce a biosecurity risk.

PO 3.2 Development minimises the potential for the harmful effects of turbidity, sedimentation, pollution, shading and effects on water flows of the marine environment both inside and outside of the zone.

PO 3.3 Development avoids important nesting or breeding areas and areas that are important for the movement/migration patterns of fauna

PO 3.4 Development avoids delicate or environmentally sensitive coastal areas and key habitat areas within and adjacent offshore islands such as sand dunes, cliff tops, estuaries, wetlands, mangroves and samphire areas.

The proposed development has been designed to minimise the impact on the marine and coastal environment.

Although not small scale, the proposed development relates to the export of grain grown within the wider region and is a significant contribution to the regional economy. Wallaroo has a long history of grain export and as a result there have been multiple man-made alterations to the coast. The proposed wharf is considerably shorter than the existing Viterra export infrastructure.

The enclosed Marine Ecological Assessment at Appendix K concludes that the proposal would result in the direct loss of a very small fraction of the total seagrass and reef habitat in the region. The loss of reef habitat would be offset to some degree by the artificial reef provided by the breakwater.

There may be additional local indirect losses of seagrass during construction and operation of the breakwater, through turbidity and sedimentation, which may require additional offsets once the extent has been quantified. Use of the south-eastern PTAA would likely result in the loss of Halophila seagrass.

Other impacts from the project, including underwater noise, introduced pests and interactions with marine megafauna can be minimised through the adoption of various management measures.

The project is not expected to impact the sustainability, annual catches or operational costs of commercial fisheries in the region, but the use of the south-western and south-eastern PTAAs would potentially impact stock assessment surveys for the Spencer Gulf Prawn Fishery.

The enclosed Core Placement Plume Dispersion Modelling at Appendix M concludes:

A hydrodynamic and cohesive sediment transport model was developed to quantitatively assess the advection-dispersion of fine suspended sediment plumes associated with the proposed breakwater construction activities for the Wallaroo Grain Terminal.

22 50510REP01

A total of nine modelling scenarios consisting of three construction phases and three environmental conditions were simulated to predict the suspended sediment concentrations due to the construction work. Fine sediment release rates were estimated based on the core placement productivity rate and a conservative assumption of up to 1.5 per cent of fines would be released during construction.

Overall, the magnitudes of suspended sediment concentration are similar for all of the scenarios. As expected, suspended sediment concentrations are the greatest at the near bed region, reducing towards the surface due to vertical mixing.

For all of the scenarios, the 90th percentile suspended sediment concentrations typically remain below 10mg/L in the whole study area except within a 100-metre radius of the construction point.

In this assessment typical (representative) parameter settings have been used as input to the model. However, the results are unlikely to be sensitive to these parameter settings, and it is concluded that any material brought into suspension during the construction operation will have a limited extent of dispersion, and will mainly re-settle onto the seabed close to the release locations.

Given the above, we have formed the view that the proposed development will not have a detrimental impact on the marine or coastal environments and is an appropriate form of development within the zone.

6.1.2 Costal Areas Overlay

The subject site is located within the Coastal Areas Overlay. The following provisions are considered the most relevant to the assessment of the application.

The Desired Outcome of the overlay is as follows:

DO 1 The natural coastal environment (including environmentally important features such as mangroves, wetlands, saltmarsh, sand dunes, cliff tops, native vegetation, wildlife habitat, shore and estuarine areas) is conserved and enhanced; provision is made for natural coastal processes; and recognition is given to current and future coastal hazards including sea level rise, flooding erosion and dune drift to avoid the need, now and in the future, for public expenditure on protection of the environment and development.

As detailed in Section 6.1.1 above, the proposed development has been designed to minimise the impact on the marine and coastal environment. We have formed the view that the proposed development will not have a detrimental impact on the marine or coastal environments and is an appropriate form of development on the subject site.

The following PO are considered the most relevant to the assessment of the application.

PO 2.1 Buildings sited over tidal water or that are not capable of being raised or protected by flood protection measures in the future are protected against the standard sea flood risk level and 1m of sea level rise.

23 50510REP01

No buildings are proposed within the Coastal Areas Overlay however the proposed wharf and associated infrastructure is to be provided with appropriate protection from sea level rise and storm surge events.

PO 2.3 Development will not create or aggravate coastal erosion or require coast protection works that cause or aggravate coastal erosion

PO 4.1 Development will not unreasonably affect the marine and onshore coastal environment by pollution, erosion, damage or depletion of physical or biological resources; interference with natural coastal processes; or the introduction of and spread of marine pests or any other means.

PO 4.2 Development avoids delicate or environmentally sensitive coastal areas such as sand dunes, cliff tops, estuaries, wetlands or substantially intact strata of native vegetation.

PO 4.3 Development allows for ecological and natural landform adjustment to changing climatic conditions and sea levels, by allowing landward migration of dunes, coastal wetlands, mangrove and samphire areas.

PO 4.4 Development avoids, or in built up areas minimises, impacts on important habitat areas that support the nesting, breeding and movement/migration patterns of fauna, including threatened shorebirds.

The enclosed Marine Ecological Assessment and Core Placement Plume Dispersion Modelling conclude that the proposal would result in the direct loss of a very small fraction of the total seagrass and reef habitat in the region and, in all simulations of the sediment plume modelling, the 90th percentile suspended sediment concentration falls below 10 mg/L within 100 metres of the source point.

Given the above, we have formed the view that the proposed development will not have a detrimental impact on the marine or coastal environments and is an appropriate form of development for the subject site.

PO 5.1 Development maintains or enhances appropriate public access to and along the foreshore.

The proposed development will not restrict public access to the foreshore and all anticipated vehicles travelling along Chatfield Terrace will retain clear and safe access.

6.1.3 Hazards (Acid Sulphate Soils) Overlay

The Desired Outcome of the overlay seeks that development is located and undertaken to minimise disturbance of potential or actual acid sulphate soils and/or the release of acid drainage.

According to the South Australian Property and Planning Atlas, the nearest areas of acid sulphate soils are located 1.6 kilometres east, either side of the ferry harbour.

It is therefore considered that there is minimal risk that the proposal would disturb existing areas of identified acid sulphate soils.

24 50510REP01

6.1.4 Historic Shipwrecks (State) Overlay

The Desired Outcome of the overlay seeks that historic shipwrecks and historic relics are protected from encroaching development.

According to the South Australian Property and Planning Atlas, there are no know historic shipwrecks within the immediate vicinity of the site. During hydrographic survey only one anomaly was noted which could have indicated a shipwreck. This anomy was inspected during the fieldwork for the marine ecological assessment and it was determined that is was not a shipwreck.

6.1.5 Native Vegetation Overlay

The following provisions are considered the most relevant to the assessment of the application.

DO 1 Areas of native vegetation are protected, retained and restored.

PO 1.1 Development avoids, or where it cannot be practically avoided, minimises the clearance of native vegetation taking into account the siting of buildings, access points, bushfire protection measures and building maintenance.

PO 1.2 Native vegetation clearance in association with development avoids the following:

(a) significant wildlife habitat and movement corridors(b) rare, vulnerable or endangered plants species(c) native vegetation that is significant because it is located in an area which has

been extensively cleared(d) native vegetation that is growing in, or in association with, a wetland

environment.

PO 1.4 Development enhances biodiversity and habitat values through revegetation.

The proposed development has been designed to minimise the impact on the marine and coastal environment inclusive of vegetation.





25 50510REP01

6.1.6 Bulk Handlings and Storage Facilities

The following provisions are considered the most relevant to the assessment of the application.

DO 1 Facilities for the bulk handling and storage of agricultural, mineral, petroleum, rock, ore or other similar commodities are designed to minimise adverse impacts on transport networks, the landscape and surrounding land uses.

PO 1.1 Bulk handling and storage facilities are sited and designed to minimise risks of adverse air quality and noise impacts on sensitive receivers

In relation to noise, an Acoustic Assessment has been prepared by Sonus and is enclosed at Attachment H.

The assessment concludes that:

The predicted noise levels account for the highest level of concurrent activity expected at the facility, as well as the noise levels from a ship in port, for weather conditions which are most conducive to noise propagation.

The highest predicted noise levels at the nearest dwellings from site activity are 49 dB(A) within the Primary Production Zone and 45 dB(A) within the Residential Zone at any time during operation. Therefore, the most onerous night-time criteria of 50dB(A) and 45dB(A) for the Primary Production and Residential zones, respectively, applicable under the Environment Protection (Noise) Policy 2007 (the Policy), have been achieved for all operations at the facility.

Based on the above, the proposal does not unreasonably interfere with the amenity and minimises adverse impacts on the locality, and therefore is considered to meet the noise related provision of the Copper Coast Council Development Plan.

An air quality assessment has been prepared by SLR and is enclosed at Attachment I.

The air quality report considers dust and fumigation emissions from the proposed development.


• That co-occurrence of worst-case operation conditions and worst-case dispersion/exposureconditions can result in an exceedance of the Air EPP PM10 assessment criterion; however, thelikelihood of this occurring is considered to be low risk. Also, a dust management plan will beprepared.

• The PM2.5 (particulate matter with equivalent aerodynamical particle diameter of 2.5 μm or less)results show that the Air EPP assessment criteria contours are largely contained within theharbour loading and bunker storage facility boundaries and there is margin to the Air EPP criteriaat the nearest receptors for both the maximum daily and annual average predictedconcentrations.

26 50510REP01

• The Total Suspended Particulate (TPS) matter results show that there are some hours withelevated TSP dust concentrations. However, it is expected that the operations can take placewithout nuisance issues.

• The worst-case conditions for the fumigation show exceedances for the nearest receptors. Withreduction in the fumigation exhaust ventilation rate the fumigant Air EPP assessment criteria canbe met.

As such it is considered that dust and fumigation emissions and acoustic impacts from the proposed development can be appropriately managed.

PO 2.1 Bulk handling and storage facilities incorporate a buffer area for the establishment of dense landscaping adjacent road frontages.

PO 2.2 Bulk handling and storage facilities incorporate landscaping to assist with screening and dust filtration.

The portion of the proposed development subject to Planning and Design Code is entirely a marine environment. As such there is no opportunity to establish landscape buffer.

PO 3.1 Roadways and vehicle parking areas associated with bulk handling and storage facilities are designed and surfaced to control dust emissions and prevent drag out of material from the site.

Although not subject to assessment under the Planning and Design Code, the proposed roadways and vehicle parking areas and to be appropriately constructed in order to minimise dust and prevent drag out of material.

PO 4.1 Slipways, wharves and pontoons used for the handling of bulk materials (such as fuel, oil, catch, bait and the like) incorporate catchment devices to avoid the release of materials into adjacent waters.

The proposal has been designed to minimise the potential for release of materials into the marine environment. The out loading of grain into the transhipment vessel will occur using a telescopic discharge probe which transfers the material directly into the hold of the vessel.

6.2 Development Plan

The terrestrial facilities proposed are located in the Bulk Handling Zone and the Coastal Open Space Zone of the Copper Coast (DC) Development Plan – Consolidated 23 May 2019.

The following sections provides an assessment of the most relevant provisions of the Development Plan.

6.2.1 Bulk Handling Zone

The objectives of the of the Bulk Handling Zone are relevant to the silo site and are as follows:

Objective 1: A zone in which agricultural and other commodities are received, stored and dispatched in bulk.

27 50510REP01

Objective 2: Buildings and structures screened from adjoining areas by landscaping, using locally indigenous plant species where possible.

Objective 3 and Principle of Development Control (Principle) 5 of the zone seeks development that is consistent with the desired character for the zone.

The Desired Character states the following:

Facilities for the transportation, handling and storage of farm commodities in bulk are an essential component of the rural economy. The townships of Paskeville and Wallaroo contains essential infrastructure for the bulk handling, storage and export of farm commodities, in particular, the deep sea port at Wallaroo which services export markets.

The facilities are integral to the rural economy and will be protected from encroachment by incompatible development or activities likely to be affected by continued operation of them. In particular the facilities at Wallaroo are of strategic importance to the economy of the State.

Because of the extensive nature of storage facilities associated with the use landscaping will be stablished around the perimeter of the land to screen the development from view from adjoining roads and residential areas, and where appropriate landscaped mounding will be used to minimise noise impacts on nearby residential areas.

The proposed development of the silo site is to facilitate the receival, storage and dispatch of bulk agricultural commodities which is expressly envisaged within the objectives and desired character of the zone.

The proposed use forms an important component of the grain export process and contributes significantly to the regional economy as envisaged in the Desired Character of the Zone.

The site essentially sits within the shadow of the existing Viterra silo facility when viewed from the Wallaroo township. Further, the nearest dwellings to the site which front Phillips Street are separated by a large allotment containing established native vegetation.

Notwithstanding this, the site contains extensive areas of undeveloped land that can accommodate landscaping as required. The proposal also contains three stormwater swales which provide further visual interest.

The proposed development is consistent with the objectives and desired character of the zone.

Principle 1 of the zone states:

PDC 1 The following forms of development are envisaged in the zone:

▪ bulk handling and storage facility▪ office and workers’ amenities (operating as an adjunct to a bulk handling use of

the site)▪ road transport terminal▪ value-adding industries associated with bulk commodities.

The proposed development is considered to fall within the gambit of a bulk handling and storage facility and is therefore an envisaged use within the zone in accordance with Principle 1.

28 50510REP01

PDC 4 Development should not impede the on-going operation of facilities associated with the handling and storage of bulk commodities.

The proposed development is considered to be complementary to the existing adjacent bulk handling and storage facilities.

PDC 6 Development of land shown on Concept Plan Map CoCo/1 - Bulk Handling (Wallaroo) should be carried out in accordance with the concepts outlined

The proposed development is consistent with Concept Plan Map CoCo/1 – Bulk Handing (Wallaroo).

PDC 7 Development associated with the handling and storage of bulk commodities, or value-adding processing, should be undertaken in a manner that minimises adverse off-site impacts on sensitive land uses.

The proposed development has been sited and designed, with the assistance of expert advice, in order to minimise adverse impacts on sensitive land uses. This is discussed in greater detail under Section 6.2.3 of this report.

The proposed use of the land for the receival, storage and dispatch of primary produce in the form of grain that will be grown, harvested and farmed throughout the wider region is considered to be an appropriate and envisaged from of development within the zone.

6.2.2 Coastal Open Space Zone

The relevant objectives of the zone are as follows:

Objective 1: To enhance and conserve the natural features of the coast including visual amenity, landforms, fauna and flora.

Objective 2: Low-intensity recreational uses located where environmental impacts on the coast will be minimal.

Objective 4 and Principle 6 seeks development that is consistent with the desired character of the zone.

The following are relevant extracts of the Desired Character:

Access to the coast itself is limited to existing roads and access tracks, limited by the expanse of farming activity adjoining the zone. As such, Wallaroo, Port Hughes and Moonta Bay provide an important base for the commercial and recreational fishing industry within the region. In recognising the significance of the local fishing industry, Wallaroo, Moonta and Port Hughes will continue to maintain this function.

As the zone abuts the coast, it is affected by coastal storm tide flooding and erosion and this risk will increase in the event of future sea level rise due to global warming. No development will be undertaken unless it relates specifically to the conservation of land, or to aquaculture or water desalination where the main infrastructure for these uses is located on existing cleared land.

Development will protect threatened flora species specific to this area including Myoporum parvifolium, Orobanche cernau var. Australiana, Austrodanthonia (syn. Rytidosperma) tuckeri, Podolepis jaceoides and Maireana rohrlachii.

29 50510REP01

The following principles are relevant to the proposal:

PDC 7 Development should be designed and sited to be compatible with conservation and enhancement of the coastal environment and scenic beauty of the zone.

PDC 8 Development should:

(a) not adversely impact on the ability to maintain the coastal frontage in a stableand natural condition

(b) minimise vehicle access points to the area that is the subject of the development(c) be landscaped with locally indigenous plant species to enhance the amenity of

the area and to screen buildings from public view(d) utilise external low reflective materials and finishes that will minimise glare and

blend in with the features of the landscape.

PDC 10 Development should:

(a) be self-sufficient in terms of infrastructure and services, such as water,sewerage, electricity and waste disposal, unless existing infrastructure isavailable that can accommodate the projected demand from the development

(b) minimise impacts on the natural surrounding environment by containingconstruction within a tightly defined site boundary

(c) not obscure existing views to coastal features or be visibly prominent from keypublic vantage points, including public roads or car parking areas

(d) avoid areas that may endanger or threaten important nesting or breeding areasor the movement/migration patterns of fauna.

The proposed development will protect access to the coast via the existing road network. The desired character contemplates development of aquaculture or water desalination where located on existing cleared land. The proposed conveyor and wharf are sited over previously cleared land within the zone. The design of the proposal ensures that linear access along the coastal reserve is preserved, even when the loading of a vessel is occurring. Although not aquaculture or water desalination, the proposed development relates to the export of grain grown within the wider region and is a significant contribution to the regional economy.

Wallaroo has a long history of grain export and as a result there have been multiple alterations to the coast.




30 50510REP01


The enclosed Core Placement Plume Dispersion Modelling at Appendix M concludes:

A Delft3D hydrodynamic and cohesive sediment transport model was developed to quantitatively assess the advection-dispersion of fine suspended sediment plumes associated with the proposed breakwater construction activities for the Wallaroo Grain Terminal.

A total of nine modelling scenarios consisting of three construction phases and three environmental conditions were simulated to predict the suspended sediment concentrations due to the construction work. Fine sediment release rates were estimated based on the core placement productivity rate and a conservative assumption of up to 1.5 per cent of fines would be released during construction.

Overall, the magnitudes of suspended sediment concentration are similar for all of the scenarios. As expected, suspended sediment concentrations are the greatest at the near bed region, reducing towards the surface due to vertical mixing.

For all of the scenarios, the 90th percentile suspended sediment concentrations typically remain below 10mg/L in the whole study area except within a 100-metre radius of the construction point.

In this assessment typical (representative) parameter settings have been used as input to the model. However, the results are unlikely to be sensitive to these parameter settings, and it is concluded that any material brought into suspension during the construction operation will have a limited extent of dispersion and will mainly re-settle onto the seabed close to the release locations.

6.2.3 Interface between Land Uses

The following provisions are from the General Section which relate to the interface between land uses.

General Section – Bulk Handling and Storage Facilities

PDC 1: Facilities for the handling, storage and dispatch of commodities in bulk should be:

(a) located in bulk handling, industry or primary production type zones(b) sited, designed and operated to minimise risks of contamination to the

environment and adverse impacts on nearby sensitive land uses and fromsurrounding land uses.

General Section – Interface Between Land Uses

Objective 1: Development located and designed to prevent adverse impact and conflict between land uses.

Objective 2: Protect community health and amenity from adverse impacts of development.

Objective 3: Protect desired land uses from the encroachment of incompatible development.

31 50510REP01

PDC 1: Development should not detrimentally affect the amenity of the locality or cause unreasonable interference through any of the following:

(a) the emission of effluent, odour, smoke, fumes, dust or other airborne pollutants(b) noise(c) vibration(d) electrical interference(e) light spill(f) glare(g) hours of operation(h) traffic impacts.

PDC 7 Development that emits noise (other than music noise) should include noise attenuation measures that achieve the relevant Environment Protection (Noise) Policy criteria when assessed at the nearest existing noise sensitive premises.

PDC 11: Development with the potential to emit harmful or nuisance-generating air pollution should incorporate air pollution control measures to prevent harm to human health or unreasonable interference with the amenity of sensitive uses within the locality.

PDC 18: Development within 300 metres of facilities for the handling, transportation and storage of bulk commodities should:

(a) not prejudice the continued operation of those facilities(b) be located, designed, and developed having regard to the potential

environmental impact arising from the operation of such facilities and thepotential extended operation of activities.

The two proposed silos are shorter in height in comparison to the adjacent 8 silos at the Viterra facility. Given the sites location adjacent to the existing Viterra silo facility, the proposed silos will not be an unreasonably visually prominent development within the locality. Importantly, the proposal will not encroach closer to the nearest dwellings which front Phillips Street in comparison to the Viterra facility. Sea views will also be maintained from these dwellings.

In relation to noise, an Acoustic Assessment has been prepared by Sonus and is enclosed at Attachment H.


The predicted noise levels account for the highest level of concurrent activity expected at the facility, as well as the noise levels from a ship in port, for weather conditions which are most conducive to noise propagation.

The highest predicted noise levels at the nearest dwellings from site activity are 49 dB(A) within the Primary Production Zone and 45 dB(A) within the Residential Zone at any time during operation. Therefore, the most onerous night-time criteria of 50dB(A) and 45dB(A) for the Primary Production and Residential zones, respectively, applicable under the Environment Protection (Noise) Policy 2007 (the Policy), have been achieved for all operations at the facility.

Based on the above, the proposal does not unreasonably interfere with the amenity and minimises adverse impacts on the locality, and therefore is considered to meet the noise related provision of the Copper Coast Council Development Plan.

32 50510REP01

An air quality assessment has been prepared by SLR and is enclosed at Attachment I.

The air quality report considers dust and fumigation emissions from the proposed development. The assessment concludes that:

• That co-occurrence of worst-case operation conditions and worst-case dispersion/exposureconditions can result in an exceedance of the Air EPP PM10 assessment criterion; however, thelikelihood of this occurring is considered to be low risk. Also, a dust management plan will beprepared.

• The PM2.5 (particulate matter with equivalent aerodynamical particle diameter of 2.5 μm or less)results show that the Air EPP assessment criteria contours are largely contained within theharbour loading and bunker storage facility boundaries and there is margin to the Air EPP criteriaat the nearest receptors for both the maximum daily and annual average predictedconcentrations.

• The Total Suspended Particulate (TPS) matter results show that there are some hours withelevated TSP dust concentrations. However, it is expected that the operations can take placewithout nuisance issues.

• The worst-case conditions for the fumigation show exceedances for the nearest receptors. Withreduction in the fumigation exhaust ventilation rate the fumigant Air EPP assessment criteria canbe met.

As such it is considered that dust and fumigation emissions and acoustic impacts from the proposed development can be appropriately managed.

The proposed development has been appropriately designed to minimise adverse impact on surrounding development and is considered to present appropriate interface between land uses given the location of the site and existing adjacent development.

6.2.4 Traffic and Parking

The following provisions relate to traffic, access and parking and are considered most relevant to an assessment of the proposed development:

General Section – Transportation and Access

Objective 2: Development that:

(a) provides safe and efficient movement for all transport modes;(b) ensures access for vehicles including emergency services, public

infrastructure maintenance and commercial vehicles; (c) provides offstreet parking;

(d) is appropriately located so that it supports and makes best use ofexisting transport facilities and networks; and

(e) provides convenient and safe access to public transport stops

PDC 5: Access roads (existing and proposed) servicing industrial development should be capable of accommodating heavy vehicle movements.

33 50510REP01

PDC 9: Development should provide safe and convenient access for all anticipated modes of transport.

PDC 10: Development at intersections, pedestrian and cycle crossings, and crossovers to allotments should maintain or enhance sightlines for motorists, cyclists and pedestrians to ensure safety for all road users and pedestrians.

PDC 14: Industrial/commercial vehicle movements should be separated from passenger vehicle car parking areas.

PDC 15: Development should provide for the on-site loading, unloading and turning of all traffic likely to be generated.

PDC 23: Development should have direct access from an all-weather public road.

Bulk Handling and Storage Facilities

PDC 4: Access to and from the site should be designed to allow simultaneous movement of vehicles entering and exiting in a forward direction to minimise interference to other traffic using adjacent public roads.

The proposed development accords with the relevant provisions for traffic, access and parking as:

• the proposed access points have been designed to accommodate safe entry and exit for allanticipated vehicle types in accordance with Australian Standards (Objective 2 & PDC 5 and 9);

• the internal roadway will have capacity to accommodate the anticipated maximum number heavyvehicles on-site (i.e. without vehicles queuing from the site onto Cresco Road), of which Cirqa hasconfirmed as being appropriate (PDC 5 & 9);

• the access for the staff vehicle parking is appropriately distanced from the heavy vehicle accesspoint to limit interaction with heavier vehicles and delivery trucks (PDC 14);

• appropriate vehicle manoeuvring areas have been designed in accordance with the relevantstandards (PDC 15);

• all movement into and out of the site will be to an all-weather road (PDC 23); and

• all vehicles entering and exiting the site will be provided with appropriate road widths andmanoeuvring areas to travel continuously in a forward motion (PDC 4).

A Traffic and Parking Report has been prepared by Cirqa and is enclosed at Attachment J.

The report concludes the following in relation to staff parking:

Staff and visitors associated with both the silo handling and marine loading facilities will share the parking area located on the silo site (accessed directly from Chatfield Terrace). During peak operation (i.e. when a ship is being loaded and tramming is being undertaken), a maximum of ten staff will be on-site at anyone time. Assuming that each staff member drives to the site in a separate vehicle, at least ten parking spaces would be required. Given that 16 spaces will be provided on-site, adequate on-site parking provisions will be provided to accommodate the forecast staff parking demands, with remaining spaces available for use by visitors to the site (albeit visitor numbers are expected to be very low and infrequent).

34 50510REP01

The report concludes the following in relation to the tramming of grain from the bunker site (subject of a separate application) to the subject site:

Grain will be trammed from the bunker storage facility to the silo handling facility via the use of Semi-Trailers. When operating at maximum capacity, the tramming of grain is forecast to generate in the order of 592 two-way vehicle movements over a 10-hour period. Noting that such vehicle movements will operate only between the two sites, the following peak hour vehicle movements are forecast:

• Left-out from the bunker site onto Cresco Road – 30 commercial vehicles per hour;

• Right-in from Cresco Road into the silo site – 30 commercial vehicles per hour;

• Left-out from the silo site onto Cresco Road – 30 commercial vehicles per hour;and

• Right-in from Cresco Road into the bunker site – 30 commercial vehicles per hour.

The forecast number of vehicle movements associated with the tramming of grain will readily be accommodated at both the bunker storage and silo handling commercial vehicle access points. Importantly, when assessed against the relevant Austroads Guidelines, channelised turning treatments are not warranted.

In relation to traffic movements, the report concludes:

With regard to Cresco Road, the proposed ‘Common User Export Facility’ is forecast to generate an additional 185 daily delivery vehicles, an additional 592 tramming movements (when ship loading is occurring) and up to 80 light vehicle movements on Cresco Road per day. This equates to up to an additional 857 vehicle movements across a 24-hour day (during the peak of harvest only).

The additional daily vehicle movements will not increase traffic volumes on Cresco Road above that of what would be envisaged for a road of its nature (a collector road is typically capable of accommodating in the order of up to 6,000 vpd). Given that the nature and function of Cresco Road will not change, it is considered that vehicle movements associated with the proposed ‘Common User Export Facility’ will be readily accommodated.

Given the above, we have formed the view that the proposal provides appropriate provision for parking, access and traffic management in accordance with the relevant provisions of the Development Plan.

6.2.5 Stormwater Management

The following provisions related to infrastructure and stormwater are considered most relevant to an assessment of the proposed development:

Objective 1: Infrastructure provided in an economical and environmentally sensitive manner.

PDC 1: Development should not occur without the provision of adequate utilities and services, including:

(a) electricity supply(b) water supply(c) drainage and stormwater systems(d) effluent disposal systems(e) formed all-weather public roads(f) telecommunications services.

35 50510REP01

PDC 11: The on-site storage of stormwater and water run-off for water supply purposes to development should be adopted in preference to the extension and/or augmentation of an existing reticulated water supply system where:

(a) sufficient land is available to accommodate on-site water storage at the volumesrequired

(b) roof areas of the development are sufficient to provide a water supply of avolume necessary to supply the development.

Details regarding the stormwater management techniques for the proposal are contained in the Stormwater Management Plan prepared by Triaxial at Attachment G.

The proposed stormwater management strategy includes:

• The finished floor levels (FFL) are above the 1.0 per cent AEP (100-yr ARI) ponding level on siteand are higher than existing road levels. Proposed FFLs are:

- Main Tower = 7.10 metres AHD- Pump House = 7.35 metres AHD- Lab & Office = 7.20 metres AHD- MCC Room = 7.35 metres AHD- Silos = 9.85 metres AHD- Intake Building = 10.75 metres AHD

• It is proposed to have three (3) infiltration/conveyor swales to suit the site layout and proposedsite grading. Swale properties are as follows:

SWALES TOP WIDTH (M)

BOTTOM WIDTH (M)

MAX. DEPTH (M)

20% AEP PONDING VOLUME

(M3)

1% AEP WATER LEVEL

(M AHD)

OUTLETΦ (MM)

1 4.5 1.5 0.375 475.2 6.28 375

2 4 1 0.375 38.8 7.20 375

3 7 1 0.75 51.1 6.27 375

• The maximum side slope for each swale is 1V:4H, with minimum longitudinal grade of0.2 per cent. Flatter longitudinal grade was proposed to allow infiltration of 20% AEP runoffalong the swale base.

• Stormwater in excess of the 20 per cent AEP will be temporarily detained on site.

• Site outlet pipe is a 375-millimetre diameter marine grade reinforced concrete pipe, to dischargeto the existing grated inlet pit in the road verge.

• The proposed treatment train for the site is via swales and site infiltration of first flush/veryfrequent storm event runoff. Regular maintenance of swales is recommended to ensure efficiencyfor pollution removal and stormwater conveyance.

We have formed the view that the proposal provides appropriate provision for stormwater management and is in accordance with relevant provisions of the Development Plan.

7.0 CONCLUSION

The proposed Grain Export Facility has the potential to provide economic and social benefits to South Australia through the efficient storage of grain products from the surrounding region.

The proposal will have a significant economic benefit for the Wallaroo township, the District Council of Copper Coast Council and the northern Yorke Peninsula region.

Through the creation of additional local employment opportunities, the development offers the potential to boost the population and accrue the social and community benefit which accumulates from such population growth.

We conclude that the proposed development:

• is an envisaged land use for the site located within the Bulk Handling Zone;

• Is a form of development that is reasonably anticipated to occur adjacent the coast and extendinto the marine environment;

• provides adequate infrastructure for safe and orderly traffic management throughout the site;

• provides stormwater management solutions to minimise external impacts;

• will not be unreasonably visually intrusive on the locality;

• minimises impacts by way of noise and air pollution;

• preserves appropriate access to the coast;

• will create employment opportunities and provide additional economic and social benefits for theWallaroo township and surrounding area; and

• is considered to be an orderly development.

Having regard to the nature of the subject site and locality, and the relevant provisions of the Planning and Design Code and Copper Coast Council Development Plan, the proposal is considered appropriate.

For these reasons, it is respectfully submitted that the proposal is worthy of Development Approval.
