1 INTRODUCTION

SLR Consulting Pty Ltd (SLR) was engaged by Skylife Properties Pty Ltd to conduct a Phase 1 Preliminary Contaminated Site Investigation (PSI) for a waste recycling facility at 13 Pembury Road, Minto, NSW (the Site).

The assessment was undertaken in accordance with SLR’s offer of services dated 10 February 2016 (ref: Minto Contract Review 20160210.docx).

The Phase 1 Contamination Investigation of the Site is required to address the Secretary’s Environmental Assessment Requirements (SEARs) for the preparation of an Environmental Impact Statement (EIS) for the proposed expansion of the existing Minto Waste Management Facility.

1.1 Objectives

The objectives of this project were to:

Make an assessment of the potential for land contamination to be present at the site, as a result of past and present land use activities.

Identify areas of environmental concern (AEC) and associated contaminants of potential concern (COPC) at the site.

Assess the likelihood of those COPC being present on site.

Provide recommendations for further investigation of the site (if warranted), in the context of the SEARS request.

1.2 Scope of Work

SLR undertook the following scope of work to address the project objectives:

a desktop review;

a site walkover; and

data assessment and reporting.

2 SITE IDENTIFICATION

The Site locality is presented in Figure 1.

The Site is located in an industrial area on a trapezoidal shaped parcel of land, 8957m2 in area and

approximately 160m by 30m in the east and south directions respectively and 190m by 70m in the west and north directions respectively. The Site is legally identified as Lot 1 on DP 1013852, 13 Pembury Road, Minto, New South Wales and falls within the Campbelltown City Council local government area. The Site is located within Zone IN1 General Industrial under the Campbelltown Local Environmental Plan 2015. The Site is owned by Pembury Street Pty Ltd.

Figure 1 Site Location

3 SITE SETTING

3.1 Topography

The topography of the Site and its surrounds are relatively flat terrain, with a gentle fall towards the north and northwest. The ground elevation has been mildly modified to suit operations on site and is approximately 40 – 50 m Australian Height Datum (AHD).

Resource Recovery Facility - Minto



v1.0 Page 7


3.2 Geology

The Geological Survey of NSW Wollongong 1:250 000 Geological Series Sheet 56-9 (Edition 2) 1966 indicates that the site is underlain by the boundary between Quaternary Alluvium comprising gravel deposits and sand dunes and the Triassic Liverpool Sub-Group which comprise shale with some sandstone beds.

3.3 Hydrology

The Minto facility is located within the George River Sub Catchment which is located within the Botany Bay Catchment Area.

There are no surface waterbodies located within the Site boundaries. Bow Bowing Creek runs directly adjacent to the western boundary of the Site. The portion of Bow Bowing Creek that runs along the Site’s western boundary has been converted into a concrete lined channel with a bund to separate the channel from the industrial properties to the east. McBarron Creek (which has also been converted into a concrete lined channel) runs along the southern boundary of the Site with Airds Road separating the Site and McBarron Creek. McBarron Creek flows into Bow Bowing Creek which flows into Georges River approximately 9.5km downstream of the Site. Georges River ultimately discharges into Botany Bay.

Campbelltown City Council advises that all properties within the Campbelltown City local government area may be affected by flooding caused by overland flow or local topography. Council are currently undertaking a flood study of the Bow Bowing / Bunbury Curran Creek Catchments, of which the property is a part. There results of the flood study are not yet available and there is currently no flood mapping for this area, but given the Site’s proximity to Bow Bowing Creek there is high potential for this Site to be affected by flooding.

3.4 Hydrogeology

The Commonwealth of Australia, 1:5 000 000 Hydrogeology Map of Australia, developed in 1987, indicates the Site falls within an area consisting of exposed bedrock aquifers from the Triassic Period of low-moderate productivity and non-saline groundwater.

A search of the NSW Department of Primary Industries real-time groundwater data (www.realtimedata.water.nsw.gov.au) conducted on 18 February 2016 did not reveal any real-time monitoring groundwater bores in the vicinity of the site.

A search of the Australian Government Bureau of Meteorology (www.bom.gov.au/water/groundwater) indicated the groundwater at the site falls under the Sydney Basin Central Management Area and falls in an area that has a bore density of 7 bores per 25km

2.

3.5 Soils

No intrusive investigations were undertaken as part of this study. Therefore, the underlying soils were unable to be characterised.

The facility has an impervious surface (with the exception of landscaped areas) and ground cover will not be disturbed by core operations at the facility (i.e. storing and processing of waste material).

The proposed development includes some small areas of soil excavation for the establishment of the new weighbridge.

Information obtained from Australian Soil Resource Information System (www.asris.csiro.au) indicated that the site has no known occurrence of Acid Sulfate Soils (ASS). Also, due to the topographical height of the site being 40-50m AHD and Acid Sulfate Soils (ASS) predominately being encountered at <20m AHD, ASS are not expected to be encountered on Site.

Based on information provided in the Salinity Potential in Western Sydney – 2002 Map developed by the Department of Infrastructure, Planning and Natural Resources (DIPNR) (Appendix A), the Site is located on land that has a potential for medium to high salinity to occur.

4 SITE HISTORY

A review of a selection of historical aerial photographs was undertaken. Observations made during the review are presented in Table 1.

Table 1 Aerial Photography Review

Year of Photograph Site Land Use Observations Surrounding Land Use Observations

1956 The site was vacant, containing no buildings and was covered with vegetation (mainly grass).

The surrounding areas are also vacant, containing no buildings and covered with vegetation (mainly grass). The railway line exists and the Bow Bowing Creek and McBarron Creek are natural (have not been modified into the concrete lined drainage channels they are today).

1965 The site appears as it did in 1956. Surrounding land use appears as it did in 1956.

1975 There appears to be some clearing/grading on or in the near vicinity of the site.

Bow Bowing Creek appears to have been modified from a natural creek to a formed drainage channel. Construction of buildings and roads in the areas immediately surrounding the site has commenced.

1988 The site is still vacant of buildings but the land area appears to be part of a larger allotment that contains a large warehouse building which may be the same building that is adjacent to the site today.

McBarron Creek has been modified into a drainage channel and further buildings (warehouses) and roads have been established in the areas immediately surrounding the site.

1998 The site is still vacant of buildings and appears to still be part of a larger allotment that contains a large warehouse building.

The majority of the surrounding areas appear as they do today. The block of land that the site is on appears to be still part of one allotment containing a large warehouse building.

2006 (Google Earth) In March 2006 the site is vacant of buildings but there appears to be earthworks being undertaken on the site. It appears as if the large allotment the site was part of has been subdivided. By August 2006 earthworks have ceased and concrete slabs and building footings are being laid.

Commercial/industrial warehouses as they appear today with the exception of the warehouse located directly south of the site, which at this time does not exist.

2009 (Google Earth) Buildings on the site appear as they are today.

Commercial/industrial warehouses as they appear today.

2012 - 2016 (Google Earth)

The site appears as it is today and is being used as a waste depot with evidence of waste being sorted on the uncovered forecourt areas and sediment evident on the forecourt.

Commercial/industrial warehouses as they appear today.

The aerial photography review indicates that the following potential land contaminating activities may have been undertaken on the site:

1921 – 1959: Dairy production

1959 – 1968: Potential general industrial uses

1998 – 2001: Potential transport depot with workshop

2001 to date: Operating as a refuse facility

A copy of the search record is presented in Appendix B.

4.2 Regulatory Authorities

4.2.1 NSW Environmental Protection Agency

A search of the NSW EPA contaminated land public register of records of notices (maintained under Section 58 of the Contaminated Land Act 1997) was undertaken by SLR on the 8 June 2016. With regards to the Site, the search results indicated that there are no:

Orders made under Part 3 of the Contaminated Land Management Act 1997 (CLM Act).

Approved voluntary management proposals under the CLM Act that have not been fully carried out and where the approval of the Environmental Protection Authority has not been revoked.



v1.0 Page 10


Site audit statements provided under Section 53B of the CLM Act that relate to significantly contaminated land.

Where practicable, copies of anything formerly required to be part of the public record.

Actions taken by EPA under Section 35 or 36 of the Environmentally Hazardous Chemicals Act 1985.

A search of the NSW EPA Protection of the Environment Operations Act public register of licence, applications and notices (maintained under Section 308 of the Protection of the Environment Operations Act 1997) was undertaken on 8 June 2016. The register contains information on:

Environmental protection licences

Applications for new licences and to transfer or vary existing licences

Environment protection and noise control notices

Convictions in prosecutions under the POEO Act

The results of civil proceedings

Licence review information

Exemptions from the provisions of the POEO Act or regulations

Approvals granted under clause 9 of the POEO (Control of Burning) Regulations

Approvals granted under clause 7A of the PEOE (Clean Air) Regulation

Any mandatory audits required to be undertaken in relation to a licence

Each pollution study requires to be a condition of licence

Each pollution reduction program required by a condition of a licence

Each penalty notice issued in relation to a premises.

The search results identified numerous sites containing Environmental Protection Licences on the neighbouring Pembury and Airds Roads in Minto and identified one Penalty Notice issued to Industrial Galvanizers Corporation Pty Ltd for contravening a condition of their licence (not noise) in December 2011. No further information was available.

A search of the NSW EPA public register of contaminated sites notified to NSW EPA under Section 60 of the Contaminated Land Management Act was undertaken on 8 June 2016. The search did not identify any records for the Site. There were 3 sites listed from the Minto area however none of them were for properties located adjacent to the Site.

A copy of the search records is presented in Appendix C.

4.2.2 SafeWork NSW

A search of the stored chemical information database (SCID) held by SafeWork NSW for the Site was undertaken on 20 May 2016. SafeWork NSW reported they had no records pertaining to the storage of Dangerous Goods at 13 Pembury Road, Minto, NSW.

A copy of the search results is presented in Appendix D.

4.2.3 NSW Office of Environment and Heritage

A search of the NSW Office of Environment and Heritage (OEH) State Heritage Register was undertaken on the 8 June 2016 by SLR for an area of 5km radius surrounding the Site. No Aboriginal Places were encountered however there were numerous buildings that are listed on the State Heritage Register. The location of the surrounding Heritage Listed Buildings is provided in Figure 2.

5 SITE WALKOVER

Site walkovers were undertaken by a suitably qualified and experienced SLR Consultant on the 27 November 2015 and again on the 15 August 2016. The purpose of the site walkovers was to make observations of the site and adjacent site land uses (relevant to land contamination). The initial site walkover was undertaken while the facility was being operated by the previous site owners, William Filipoppoulos and Thomas Filipoppoulos. The second site walkover was undertaken while the facility was being operated by the current operator, Minto Recycling Pty Ltd.

5.1 Site Drainage

The site gently slopes towards the north and northwest. All surface water is currently conveyed (via an existing pit/pipe network) to a Humeceptor before discharging offsite into the Campbelltown City Council (CCC) stormwater system which flows into Bow Bowing Creek (a modified concrete lined drainage channel) adjacent to the site. In addition to the pit/pipe stormwater system, bunding also exists on either side of the site to ensure that runoff is contained on-site and directed to the stormwater treatment system.

All roof water is currently directed into an underground 100 kl rainwater tank. This rainwater tank currently acts as a roofwater holding tank prior to its discharge to stormwater. No changes in the site drainage were observed between the 2015 and 2016 site walkovers.

5.2.1 Site Operations

Operations being undertaken at the site during the 2015 site inspection included resource recovery from inert wastes. Trucks were delivering waste which was being tipped on to the concrete hardstand outside the warehouse. The lighter material was moved into the warehouse for sorting/shredding, leaving the heavier materials which were then removed off-site.

5.2.2 Site Features

The following site features were observed during the 2015 walkover:

Three sheds with concrete slab floors which are used for site operations:

Shed A – Non-ferrous area/hazardous shed;

Shed B – General waste shed; and

Shed C – Processing shed.

The majority of the site is covered with concrete slabs which were observed to be in fair to good condition. The concrete joints are starting to show signs of deterioration. There were also some unsealed landscape areas along the western boundary and unsealed grassed areas along the northern boundary.

A weighbridge.

Above ground 5000L diesel tank, overhead fuel line and a diesel bowser.

Fire water pipeline running along the eastern boundary.

100 000L onsite stormwater detention tank.

Humeceptor for stormwater treatment.

Four material storage bays.

Car parking bays.



v1.0 Page 17


Site features observed in 2015 are presented in the site layout plan in Figure 3, while photographic evidence is provided in Appendix F.

5.2.3 Wastes

The site was used to receive, sort and recycle general solid wastes. Numerous empty waste bins and 205L drums used to transport the recycled wastes to site were evident across the site. A front lift skip bin was available on site for collection of general waste generated by the site employees and there were a few used batteries and gas cylinders stored on pallets waiting for removal from site for appropriate disposal. The batteries and gas cylinders are encountered while sorting the received general solid wastes.

5.2.4 Chemical Use and Storage

Chemical usage and storage observed during the site inspection included:

5000L above ground diesel tank, overhead fuel line and associated bowser, which are stored undercover in Shed A. There was no bund around the tank, bower area or at the entrance to the shed however the floor to the shed slopes inwards so in the event of a spill the diesel would flow back into the shed.

1000L portable plastic tank (IBC) containing diesel additive (a urea solution) located next to the above ground diesel tank in Shed A.

1000L portable plastic tank (IBC) containing waste oil in the workshop. Some small drums containing coolant and oil within Shed A.

These chemicals were used for operation of the onsite machinery and stored undercover within Shed A.

5.2.5 Asbestos

Due to the sites’ buildings having been built in 2006-2007 there is unlikely to be asbestos contained in the structures.

No asbestos fragments were observed in the waste being handled on site during the site walkover, although there is potential for additional waste asbestos products to be brought onto the site mixed with the delivery of the inert wastes. The Draft Operational Environmental Management Plan (OEMP) for the site incorporates protocols to enable the appropriate management of nonconforming wastes including asbestos.

It is noted that a hazardous building materials survey was not within the scope of this investigation.

5.2.6 Phytotoxicity

All vegetation on site appeared healthy and showed no signs of phytotoxic impact.

5.2.7 Odours and Staining

There was no olfactory evidence of odours on the site, with the exception of odours generally associated with inert waste. There was no visual evidence of widespread or significant staining on the hardstand during the site walkover.



v1.0 Page 18


5.2.8 Adjacent Land Uses

The site is located within an established light industrial/commercial area and is surrounded by light industrial warehouses undertaking low risk contaminating activities, including an office equipment supplier, auto repair shops, consulting engineers and freighters. There was no visual or olfactory evidence of migration of contamination from adjacent land users.

5.3 August 2016 Site Walkover (current site operators)

5.3.1 Site Operations

Operations being undertaken at the site during the 2016 site inspection included resource recovery from inert wastes within Shed B. Sheds A and C were not being used for waste storage or processing during the site inspection. Trucks were delivering waste which was being tipped on to the concrete hardstand inside Shed B, where it was being sorted for recycling.

5.3.2 Site Features

The following site features were observed during the 2016 walkover:

Three sheds with concrete slab floors which are used for site operations:

Shed A – Currently empty of waste;

Shed B – General waste receiving shed including 5 x 250L drums containing sorted copper, aluminium and other metals; and

Shed C – Currently empty of waste.

The majority of the site is covered with newly laid concrete slabs which were observed to be in excellent condition. There are some areas that are still covered with old concrete, which was observed to be in fair condition, however the joints have deteriorated.

The unsealed landscape areas along the western boundary and unsealed grassed areas along the northern boundary remained.

A renovated weighbridge office.

The above ground 5000L diesel tank, overhead fuel line and a diesel bowser have been removed.

A new double walled, self bunded, 30,280 L diesel tank. Information obtained from the client suggested that a bund wall will be constructed surrounding the tank, which will separate the tank area from the rest of the site area.

Fire water pipeline running along the eastern boundary remained.

100 000L onsite stormwater detention tank remained.

Humeceptor for stormwater treatment remained.

Four external material storage bays previously found on site have been removed.

Car parking area remained. Majority of the car parking area was vacant with some minor storage of inert construction materials.

Site features observed in 2016 under the current operators are presented in the site layout plan in Figure 4 while photographic evidence is provided below.

The likelihood of contamination being present from historic activities has been determined as low even though the site was potentially unsealed for a period of time. The potential for the contaminating activities to have actually occurred on the site is deemed as being very low since the site was subdivided from a larger commercial/industrial site with no previous signs of development on the actual site.

It should be noted that the likelihood of contamination being present from current land activities (AEC 01-02) and previous occupiers (AEC 03) has been determined as low-medium due to the majority of the site being covered in fair to good condition hardstand, restricting the pathway for contaminants to enter underlying soils, however there is a higher potential for the contaminating activities to have actually occurred, as the activities were undertaken on the actual site.

8 CONCEPTUAL SITE MODEL

Potential contamination migration pathways between sources of contamination and potential identified receptors are presented in Table 3 below.

Table 3 Potential Contaminant Pathways and Receptors

PATHWAYS HUMAN HEALTH RECEPTORS ENVIRONMENT RECEPTORS

Direct dermal contact with contaminants

Workers and visitors during the demolition/construction phase of the Site

Future/current maintenance/construction workers

Impact on off-site and on-site fauna

Inhalation of soil dust, fibres and/or soil vapours

Workers and visitors during the demolition/construction phase of the Site


General public or workers in neighbouring properties during demolition/construction phase of the Site


Ingestion of contaminated soil/water

Workers or visitors during the demolition/construction phase of the Site


Users of groundwater/surface water down-gradient of project area


Impact on off-site aquatic eco-systems

The preferential pathways identified for contaminant migration to occur include:

Surface water drains via runoff

Subsurface drains via runoff and leaching

Vapour/groundwater flow through service trenches

Potential entry of vapours into buildings through service penetrations and cracks in the building fabric (future)

9 CONCLUSIONS AND RECOMMENDATIONS

Based on a review of the available desktop search data and observations made during the site walkover with the context of the objectives of this investigation, SLR makes the following conclusions and recommendations:

1. Some AECs have been identified on the site, based on past and current land use activities, including:

Waste Handling

Fuel storage and handling

Use of the site as a Transport Depot (including workshop and decommissioned oil/water separator)

Historic on-site activities including dairy farming, general industrial uses, transport depot and importation of fill

2. No AECs have been identified in association with potential off-site sources of contamination.

3. The qualitative likelihood of soil contamination being present on the site, as a result of the identified AECs, is considered low to medium.

4. An additional investigation in the form of soil sampling would be recommended, to refine the level of certainty around the likelihood of contamination being present at the site, particularly in areas where future soil disturbance is proposed, so an assessment can be made in relation to the safety of the workers who may come into contact with the soil during soil disturbance works.

5. Further contamination investigation work should be undertaken by a suitably experienced environmental consultant.

6. The site in its current state is suitable for commercial/industrial activities.

did not find any records in our database.

If a site does not appear on the record it may still be affected by contamination. For example:

• Contamination may be present but the site has not been regulated by the EPA under the Contaminated Land Management Act 1997 or the Environmentally Hazardous Chemicals Act 1985.

• The EPA may be regulating contamination at the site through a licence or notice under the Protection of the Environment Operations Act 1997 (POEO Act).

• Contamination at the site may be being managed under the planning process.

More information about particular sites may be available from:

• The POEO public register

• The appropriate planning authority: for example, on a planning certificate issued by the local council under section 149 of the Environmental Planning and Assessment Act.

See What's in the record and What's not in the record.

If you want to know whether a specific site has been the subject of notices issued by the EPA under the CLM Act, we suggest that you search by Local Government Area only and carefully review the sites that are listed. This public record provides information about sites regulated by the EPA under the Contaminated Land Management Act 1997, including sites currently and previously regulated under the Environmentally Hazardous Chemicals Act 1985. Your inquiry using the above search criteria has not matched any record of current or former regulation. You should consider searching again using different criteria. The fact that a site does not appear on the record does not necessarily mean that it is not affected by contamination. The site may have been notified to the EPA but not yet assessed, or contamination may be present but the site is not yet being regulated by the EPA. Further information about particular sites may be available from the appropriate planning authority, for example, on a planning certificate issued by the local council under section 149 of the Environmental Planning and Assessment Act. In addition the EPA may be regulating contamination at the site through a licence under the Protection of the Environment Operations Act 1997.
