EXECUTIVE SUMMARY

Aargus Pty Ltd (‘Aargus’) was appointed by Blue Fountain Trust C/- Marchese Partners

International Pty Ltd (the ‘client’) to undertake a Preliminary Site Investigation (PSI) within

the property located at 13 Mount Street, Mount Druitt NSW (the ‘site’). The eastern portion

of the site is proposed to be partially redeveloped into a six-storey commercial building with

three levels of basement car parking, whilst the western portion of the site is to be retained for

existing commercial uses.

A PSI was requested by the Council to determine the potential for onsite contamination. This

report shall provide a preliminary assessment of any site contamination and, if required,

provide a basis for a more detailed investigation.

At the time of the inspection (26th June 2019), the majority of the site was occupied by one

large building across the northern half of the site, whilst a concrete/bitumen driveway/car

parking area occupied the southern half of the site.

The land title information provided suggested that the site was owned by various government

agencies from 1970 to 1989, then private owners between 1989 and 2005. The site was

owned by to ING Management Ltd from 2005 to 2009, Blacktown City Council between

2009 and 2012, AET Structured Finance Services Pty Limited from 2012 to 2017, and finally

acquired by Angel Buck Investments Pty Ltd from 2017 to the current date.

The findings of the assessment indicated the following areas of potential environmental

concern those being importation of uncontrolled fill; car park areas; the adjoining service

station operations; and asbestos based building materials.

The contaminants that may be present in some of these areas were considered to be of low to

moderate significance in terms of risk to the human and environmental receptors identified.

Therefore, a Detailed Site Investigation (DSI) is required to confirm the presence and extent

of contamination in order to determine the suitability of the site for the proposed development

application and to address the data gaps identified. It is also recommended that a hazardous

material assessment be undertaken followed by an asbestos clearance certificate.


© Aargus Pty Ltd

Based on the information collected during this investigation and in reference to Clause 7 (DA

development of SEPP 55), the site will be suitable subject to the completion of a Detailed

Site Investigation (and after remediation and validation, if required) for the proposed

commercial development.

1 INTRODUCTION

1.1 Background

Aargus Pty Ltd (‘Aargus’) was appointed by Blue Fountain Trust C/- Marchese Partners

International Pty Ltd (the ‘client’) to undertake a Preliminary Site Investigation (PSI) within

the property located at 13 Mount Street, Mount Druitt NSW (the ‘site’). The location of the

property is presented in Figure 1 of Appendix A.

It is understood that the site is proposed for the partial demolition of the eastern most portion

of the existing building and redeveloped into a six-storey commercial building with three

levels of basement car parking, whilst the western portion of the site is to be retained for

existing commercial uses. The proposed development plans can be found in Appendix B and

the proposed construction layout is shown in Figure 4 of Appendix A.

A site investigation was requested by Council to determine the potential for onsite

contamination as part of the Development Application (DA).

1.2 Objective

The primary objectives of this PSI are as follows:

• Identify potential areas where contamination may have occurred from current and

historical activities;

• Identify potential contaminants associated with potentially contaminating activities;

• Assess the potential for soils and groundwater to have been impacted by current and

historical activities; and

• Assess the suitability of the site for redevelopment into a six-storey commercial

building with three levels of basement car parking, based on its current condition and

the findings of this investigation.


© Aargus Pty Ltd

1.3 Scope of Works

The scope of works for this PSI includes:

• Review of the physical site setting and site conditions based on a site inspection,

including research of the location of sewers, drains, holding tanks and pits, spills,

patches of discoloured vegetation, etc. (where applicable);

• Research and review of the information available, including current and historical

titles information, review of aerial photographs, groundwater bore searches, EPA

notices, anecdotal evidence, site survey and site records on waste management

practices;

• Development of a preliminary Conceptual Site Model (CSM) to demonstrate the

interactions between potential sources of contamination, exposure pathways and

human/ecological receptors identified; and

• Recommendations for additional investigations should any data gaps be identified or

possible strategies for the management of the site, where relevant.

This report was prepared with reference to the NSW Environment Protection Authority

(EPA) "Guidelines for Consultants Reporting on Contaminated Sites" (2011).

2.2 Site Inspection

A site visit was carried out on Wednesday 26th June 2019 by an Aargus field scientist to

inspect the site for any potential sources of contamination and document any observations

made regarding the current site conditions. At the time of the site inspection, the following

observations were made:

• The site is almost rectangular in shape.

• The majority of the site was occupied by one large building across the northern half of

the site, whilst a concrete/bitumen driveway/car parking area occupied the southern

half of the site.

• The building was utilised as a Hotel, medical centre, cash loans office, employment

service offices, and fast food restaurants.

• The driveway / car parking area was concrete/bitumen sealed, generally in a good

condition with minor cracks and oil staining.

• A concrete drive accessway was located in the centre of the building.

• A Caltex service station was located on the adjoining north eastern property.

• Entrance to the site was from the concrete/bitumen driveway along Mount Street on

the eastern side and a car park on the western side.

• The site boundaries were defined by the building to the north and a grass area and

construction site to the south. The eastern and western boundaries were defined by the

building and open access ways.

• No surface standing water was noticed at the site, with multiple drainage pits observed

in the car park / drive way areas.

• No USTs were observed on the site.

The site features are presented in Figure 3 of Appendix A. Site photographs are included in

Appendix C.

2.3 Topography and Surface Water Drainage

The following observations were made during the site inspection carried out on Wednesday

26th June 2019:

• The site is slightly sloping from the western and eastern boundaries towards the centre

of the site.

• Stormwater runoff from the site is expected to flow towards the stormwater drainage

at the centre of the site.

• According to the topographic map of Mount Druitt, the general slope of the area is

towards the south west of the site with the site at a higher elevation.

In summary, the land title information provided suggested that the site was owned by various

government agencies from 1970 to 1989. Antonio Falcone, Mario Falcone, Raymond Nasso

and Mario Nasso owned the site between 1989 and 1993. The site was owned by Antonio

Falcone, Mario Falcone 1993 to 2005. The site was owned by to ING Management Ltd from

2005 to 2009. Blacktown City Council owned the site between 2009 and 2012. The site was

owned by AET Structured Finance Services Pty Limited from 2012 to 2017.The site was

acquired by Angel Buck Investments Pty Ltd from 2017 to the current date. Based on Aerial

Photographs from 1977 the land appears to be vacant. Hence, land title information prior to

1970 was not researched.

A copy of the land titles information obtained by Aargus can be found in Appendix D.


© Aargus Pty Ltd

3.2 Aerial Photographs

Selected aerial photographs obtained from the NSW Department of Lands were reviewed to

describe the site features and surrounding areas at various timelines. A summary of the

review is presented in the table below.

Table 4: Summary of Historical Aerial Photos

Year Site Surrounding areas

1977 The site is a vacant tree covered block of land. N: A road, then vacant tree covered land

S: A road, then vacant tree covered land

E: A road, then vacant tree covered land

W: A road, Commercial buildings and tree

covered land

2004 The northern portion of the site is occupied by a

commercial building, whilst the southern

portion by a concrete/bitumen driveway and car

park.

N: A road, then industrial/commercial buildings

S: A vacant site with grass bed, then a road

E: A road, then industrial/commercial building

W: An commercial site with car park

In summary, land use of the site and the adjoining properties appeared to have been initially

vacant land till at least 1977 and then redeveloped into industrial/commercial land uses.

Copies of current and historical aerial photographs are presented in Appendix E.

3.3 EPA Records

3.3.1 CLM Act 1997

The NSW EPA publishes records of contaminated sites under Section 58 of the Contaminated

Land Management (CLM) Act 1997. The notices relate to investigation and/or remediation

of site contamination considered to pose a significant risk of harm under the definition in the

CLM Act. However, it should be noted that the EPA record of Notices for Contaminated

Land does not provide a record of all contaminated land in NSW.


© Aargus Pty Ltd

The subject site, that being 13 Mount Street, Mount Druitt NSW, is not recorded on the list of

NSW contaminated sites notified to the NSW EPA.

Copies of the EPA records are included in Appendix F.

3.3.2 POEO Register

A search of the POEO Register revealed that the site was not listed. However, there is a

record of 75 Railway Street, Mount Druitt NSW (Mount Druitt Hospital) located more than

half a kilometre away from the site.

A copy of the POEO register search and the Licence Numbers is included in Appendix F.

3.4 Section 149 Certificates

Section 149 Certificates were not available at the time of writing this report.

3.5 Former Industrial Processes and Products Manufactured

Based on the site inspection, it is unlikely that any industrial processes and activity would

have previously occurred on site.

3.6 Former & Current Chemical Storage and Transfer Areas

No major chemical storage and transfer areas were identified based on the historical searches

and site inspection.


© Aargus Pty Ltd

3.7 Product Spill & Loss History

The majority of the site is currently occupied by commercial stores and sealed with

concrete/bitumen. At the time of the inspection, the sealed surfaces were generally in good

condition with minor cracking and some oil staining noted.

3.8 Discharges to Land, Water and Air

No discharges to the land, water and air were observed.

3.9 Complaints History

There was no information obtained or provided indicating any relevant complaint history

pertaining to the site.

3.10 Historical Use of Adjacent Land

Aerial photography indicated the adjoining properties appeared to have been vacant in 1977

and developed into a commercial site to the current date.

4 ENVIRONMENTAL SETTING

4.1 Sensitive Environmental Receptors

The nearest watercourse is South Creek located approximately 5.4km to the west of the site.

There is a TAFE college located south east of the site and a hospital located north east of the

site.

4.2 Soil

The Soil Landscape Map of Penrith (soil Landscape Series Sheet 9030, Scale 1:100,000,

1989), prepared by the Soil Conservation Service of NSW, indicates that the site is located

within the Blacktown landscape area and typically consists of highly plastic and relatively

impermeable residual soil.

4.3 Geology

The Geological Map of Penrith (Geological Series Sheet 9030, Scale 1:100,000, Edition 1,

1991), published by the Department of Minerals and Energy indicates the residual soils

within the site to be underlain by Triassic Age Shale of the Wianamatta Group, comprising

shale, carbonaceous claystone, claystone, laminite, fine to medium grained lithic sandstone,

rare coal and tuff.

Aargus Chameleon undertook a Geotechnical investigation for the site on the 27th and 28th

June 2019 (Chameleon Geoscience, Geotechnical Investigation Report, 13 Mount St, Mount

Druitt NSW, Ref: GS7665), with the following profile observed:

• Residual Soil - CLAY to Silty CLAY, high plasticity, orange to red brown + grey

shale gravel

• Bedrock - SHALE, grey, extremely weathered, extremely low strength, with clay

seams.


© Aargus Pty Ltd

4.4 Acid Sulfate Soils

To determine whether there is a potential for acid sulphate soils to be present within a site,

reference was made to the NSW Department of Land & Water Conservation (DLWC) but no

Acid Sulfate Soil Risk Map was available.

The NSW Government Planning & Environment website has no information regarding the

occurrence of acid sulfate soil material within the soil profile of the site

(https://www.planningportal.nsw.gov.au/spatialviewer/#/find-a-property/address).

4.5 Hydrogeology

Based on the desktop search the nearest watercourse is South Creek located approximately

5.4km to the west of the site. The site is located near a higher elevation of around 61m, hence

the groundwater flows south west of the site and discharges into the South Creek.

A search of the Department of Primary Industries borehole database information revealed

three bores within a 500m radius of the site. A summary of the three (3) closest groundwater

bores provided by the registered groundwater bore record search is provided in the following

table:

A copy of the groundwater bore search records can be found in Appendix G.


© Aargus Pty Ltd

Aargus Chameleon undertook a Geotechnical investigation for the site on the 27th and 28th

June 2019 (Chameleon Geoscience, Geotechnical Investigation Report, 13 Mount St, Mount

Druitt NSW, Ref: GS7665), with groundwater noted in borehole BH101 at 4.20m bgl

(approximate RL 52.7m AHD), and the groundwater level in BH102 at 5.40m bgl

(approximate RL 51.5m AHD). Based on maximum basement excavation depths of

approximately 9.6m to achieve a basement level of RL47.3m AHD, it is considered that

groundwater levels may be up to 5.4m below the lowest basement floor level, and would be

within the underlying weathered bedrock.

4.6 Local Meteorology

The monthly rainfall of the local area can be represented by the data collected by Bureau of

Meteorology (BOM) from the rainfall gauge located in the Erskine Park Reservoir, which is

located approximately 9.5km south west of the site. Records indicate that the annual rainfall

from 2013 to 2019 ranges from 572mm to 789.0mm. No mean annual rainfall data is

available for this station.

Reference can be made to Appendix H – Local Meteorology.

5 AREAS OF POTENTIAL ENVIRONMENTAL CONCERN

Based on the site inspection, site history, previous reports and review of available

information from the desktop study, the potential Areas of Environmental Concern (AEC)

and their associated Contaminants of Concern (CoC) for the site were identified. These are

summarised in the following table.

6 PRELIMINARY CONCEPTUAL SITE MODEL

6.1 Conceptual Site Model

The Preliminary Conceptual Site Model (CSM) presented in the table below provides a

representation of the potential risks associated with the linkages between the following

elements:

• Potential contamination sources and their associated contaminants of concern

identified in Section 5. Only potential areas of concern with a significance rating of

low to high were included;

• Potential human receptors that may be impacted by site contamination are current and

future end-users, construction workers and the general public within the immediate

vicinity;

• Potential environmental receptors identified in Section 4;

• Potential exposure pathways; and

• Whether each source-pathway-receptor pollution linkage are complete, limited or not

present, based on current and future site conditions.

6.1.1 Data Gaps

Based on the CSM, the following data gaps were identified with respect to the pollution

linkages identified:

• Confirmation if contamination has occurred from current and historical site activities

through collection and laboratory analysis of soil.

• The presence and quality of groundwater is currently unknown and may be impacted

by historical site activities and the adjacent service station.


© Aargus Pty Ltd

7 CONCLUSIONS AND RECOMMENDATIONS

The findings of the assessment indicated the following areas of potential environmental

concern those being importation of uncontrolled fill; car park areas; the adjoining service

station operations; and asbestos based building materials.

The contaminants that may be present in some of these areas were considered to be of low to

moderate significance in terms of risk to the human and environmental receptors identified.

Therefore, a Detailed Site Investigation (DSI) is required to confirm the presence and extent

of contamination in order to determine the suitability of the site for the proposed development

application and to address the data gaps identified. It is also recommended that a hazardous

material assessment be undertaken followed by an asbestos clearance certificate.

Based on the information collected during this investigation and in reference to Clause 7 (DA

development of SEPP 55), the site will be suitable subject to the completion of a Detailed

Site Investigation (and after remediation and validation, if required) for the proposed

commercial development.

Thank you for the opportunity to undertake this work. We would be pleased to provide

further information on any aspects of this report.

LIMITATIONS

The Aargus assessment is based on the result of limited site investigations and sample testing.

Neither Aargus, nor any other reputable consultant, can provide unqualified warranties nor

does Aargus assume any liability for site conditions not observed or accessible during the

time of the investigations.

Despite all reasonable care and diligence, the materials encountered and concentrations of

contaminants measured may not be representative of conditions between the locations

sampled and investigated. There is always some disparity in subsurface conditions across a

site that cannot be fully defined by investigation. Hence it is unlikely that measurements and

values obtained from sampling and testing during environmental works carried out at a site

will characterise the extremes of conditions that exist within the site. In addition, site

characteristics may change at any time in response to variations in natural conditions,

chemical reactions, truck movement or contractor movement of soils and other events, e.g.

groundwater movement and or spillages of contaminating substances. These changes may

occur subsequent to Aargus investigations and assessment.

This report and associated documentation and the information herein have been prepared

solely for the use of the client at the time or writing the report and is valid (for the purposes

of management or transport of material) for a period of one month only from the date of

issue. Any other reliance assumed by third parties on this report shall be at such parties’ own

risk. Any ensuing liability resulting from use of the report by third parties cannot be

transferred to Aargus.

Whilst this report provides a review of site conditions encountered at sampling locations

within the investigation, it should be noted that if materials are proposed to moved from site -

Part 5.6, Section 143 of the Protection of the Environment Operations (POEO) Act 1997

states that is an offence for waste to be transported to a place that cannot lawfully be used as

a facility to accept that waste. It is the duty of the owner and transporter of the waste to

ensure that all material removed from a site must be accompanied by an appropriate waste

classification report and materials are disposed of appropriately. An environmental or

differently. Aargus accepts no liability for the unlawful disposal of waste materials from any

site. Aargus does not accept any responsibility for the material tracking, loading,

management, transport or disposal of waste from the site. If material is to be removed from a

site, before disposal of any material to a licensed landfill is undertaken, the site owner must

ensure an appropriate waste classification exists for all materials on the site planning to be

removed, the waste producer will need to obtain prior consent from the licensed

landfill/recycler. The receiving site should check to ensure that the material received matches

the description provided in the report.
