Preliminary Site Investigation for Contamination, Proposed Service Centre 91401.00.R.001.Rev0 37 - 41 Bengal Street, Coolongolook December 2019

Executive Summary

This report presents the results of a preliminary site investigation (PSI) for contamination undertaken

for the proposed service centre at 37 - 41 Bengal Street, Coolongolook.

The PSI comprised a brief site history review, a desktop review of published geological and soil

landscape maps, development of a conceptual site model (CSM), drilling of 10 boreholes and limited

sampling for a range of potential contaminants.

The assessment has been undertaken with reference to the National Environment Protection

(Assessment of Site Contamination) Measure 1999 amended 2013 (NEPC 2013).

The results of the desktop assessment and site inspection indicate that a number of potential

contaminating activities have occurred at the site, such as:

Possible importation of filling within the site, particularly in the area around the existing building

and in the eastern part of the site, as encountered in Bore 6, expected behind the small retaining

walls and observed adjacent to the water body;

Possible asbestos within near surface filling from the demolition of former structures on the site;

Localised dumped filling / opportunistic dumping along water body;

Possible impact from the effluent treatment on the site.

The potential areas of environmental concern were generally localised, as shown on Drawing 1, and

associated with near surface impacts. Limited testing within and around these areas of environmental

concern returned chemical concentrations below the adopted site assessment criteria for the intended

commercial land use. It is recommended, however, that additional investigation is undertaken to

assist with development of a remediation action plan, if required.

It is suggested that the identified potential areas of environmental concern could be readily addressed

through appropriate additional investigation, and remediation (where required) to render the site

suitable for the intended commercial land use.

No assessment of groundwater was undertaken during the investigation. Given the presence of the

existing service station across the Pacific Highway, which is on the list of contaminated sites, it is

suggested that installation of groundwater wells and testing of the groundwater for potential

hydrocarbon impact should be undertaken.

Report on Preliminary Site Investigation for Contamination

Proposed Service Centre

37 - 41 Bengal Street, Coolongolook

1. Introduction

This report presents the results of a preliminary site investigation (PSI) for contamination undertaken

for the proposed service centre at 37 - 41 Bengal Street, Coolongolook. The work was undertaken for

Turnbull Planning International Pty Ltd and was undertaken with reference with Douglas Partners Pty

Ltd (DP) proposal NCL180321 dated 8 August 2018.

It is understood that the project is in the concept phase at present and the current investigation is

required as part of the development application process.

The PSI comprised a brief site history review, a desktop review of published geological and soil

landscape maps, development of a conceptual site model (CSM), drilling of 10 boreholes and limited

sampling for a range of potential contaminants.

The PSI for the site was undertaken with reference to NSW EPA Guidelines for Consultants Reporting

on Contaminated Sites (August 2011) (Ref 5) and the National Environment Protection (Site

Contamination) Measure 1999 (amended 2013 – NEPM 2013) (Ref 4).

For the purpose of the investigation, the client provided DP with the following drawings:

Proposed Site Dimensional Plan, Drawing PA001, dated January 2018;

Proposed Site Layout, Drawing PA001, dated January 2018;

Proposed Truck Movement Details, Drawing PA001, dated January 2018;

Proposed Site Pavement Plan, Drawing PA001, dated January 2018; and

Proposed Building Plan, Drawing PA001, dated January 2018.

DP has undertaken a concurrent preliminary geotechnical investigation (Ref 1).

2. Site Identification, Description and Surrounding Land Use

The site is located at 37 to 41 Bengal Street, Coolongolook and is identified as Lots 7 to 9, Section 10

in DP 758278.

Figure 1: Aerial image of site (sourced from GoogleEarth image dated September 2016)

The site is approximately 6200 m2 in area and roughly rectangular in shape.

The southern two thirds of the site (Lots 7 and 8) were cleared of vegetation at the time of the

investigation with the exception of some scattered trees in the western part of Lot 8.

Figure 4: Existing residence in Lot 9, looking north-west

A prominent gully passes through the site, entering in the south-western corner and flowing into a

culvert under the Pacific Highway on the eastern boundary of Lot 9.

The site is bounded to the east by the existing Pacific Highway, to the south by residential allotments

and to the north and west by unformed road reserves for Nelson Street and Lombard Lane

respectively.

3. Regional Geology, Acid Sulfate and Soil Landscape Mapping

Reference to the digital 1:250,000 Geological Sheet for the area indicates the site is mapped as being

underlain by Quaternary alluvium, which is characterised by channel and flood plain alluvium

comprising gravel, sand, silty and clay. Areas to the west of the site are mapped as being underlain

by the Boolambayte Formation, which is characterised by mudstone, sandstone and conglomerate.

The conditions in the bores indicated the presence of shallow alluvium overlying bedrock, described as

meta-siltstone where a highly disturbed sample was retrieved.

The site is mapped as having no known occurrence of acid sulfate soils.

4. Topography and Regional Groundwater Regime

Detailed survey of the site has not been provided to DP at this stage. Reference to the state wide

10 m digital contour mapping suggests that surface levels at the site range from about RL 10 m (within

the gully) to possibly up to RL 15 m AHD in higher areas to the south and south-west.

A groundwater bore search undertaken with the Department of Infrastructure, Planning and Natural

Resources indicated that three registered groundwater wells are located within 500 m of the site, as

follows and as shown in Figure 5:

GW200526, located approximately 300 m south of the site and up-gradient;

GW049935, located approximately 350 m south-south-east of the site and across-gradient; and

GW200403, located approximately 550 m east-north-east of the site and down-gradient.

The bores are registered as either for domestic or commercial use and have a standing groundwater

recorded at depths ranging from 4 m (GW200403) and 5 m (GW049935). No groundwater details were

provided in the report for GW200526. The subsurface conditions recorded in the wells included

predominantly clay over shale and basalt bedrock.

Groundwater at the site is expected to flow into the broad gully and then in a north-easterly direction

under the highway before entering Coolongolook River, approximately 900 m to the east of the site.

This water body is considered to be the nearest environmentally sensitive receptor.

5. Proposed Development

The proposed development includes the construction of a service centre, which will comprise the

following:

A retail food outlet and sales building in the central area of the site;

Car refuelling area and canopy;

Truck refuelling area;

Pavements surrounding the proposed structures.

The quantity of site re-grading (cut and fill) is not known at this stage. It is noted, however, that a

broad gully runs through the site and that a small water body is located in the north-western corner of

Lot 9. Hence some surface water diversion and drainage works together with placement of

engineered filling is likely to be required.

6. Site History

6.1 Extent of Site History Review

The brief site history review comprised the following:

Search for historical title deeds;

Review of historical aerial photos;

Searches with the NSW Environmental Protection Authority (EPA); and

Review of Council Planning Certificates 10.7 (2 and 5).

It is noted that the history review excluded a dangerous goods search.

6.2 Historical Title Search

A historic title deeds search was carried out by Info Search Pty Ltd, the results of which are provided

in Appendix B and summarised in Table 1 to Table 3 below. Reference should be made to Figure 6

for the location of the historical lots. The searches indicate that the site have generally been in private

hands, with the owners occupations listed as being dairy farmers as well as occupations which are

unrelated to the land.

6.4 NSW EPA Search

A review of the NSW EPA public registers indicated the following:

The site is not on the NSW EPA Contaminated Land Management Register;

The site is not on the list of contaminated sites notified to NSW EPA, although the active service

station across the Pacific Highway from the site is on the list;

Neither the site nor immediately adjacent sites are on the Protection of the Environment

Operations Act list of environmental licences, notices etc; and

The site is not on the NSW cattle dip registers.

6.5 Council DA Search

A review of the planning certificates 10.7(2 and 5) for the three lots, which were supplied by the client,

revealed the following:

The site is zoned as RU5 – Village;

The site is not within a proclaimed mine subsidence district;

The site is not reserved for acquisition;

The council has not received advice from any authority advising of the presence of loose-fill

asbestos insulation within any residence that may exist on the property; and

There are no matters declared under Section 59 (2) of the Contaminated Land Management Act

1997.

7. Site Condition

A site inspection was undertaken on 13 September 2018 by a Principal engineer from DP.

The main features and observations made of the site during the inspection are discussed below. The

location and orientation of the figures below are also shown on Drawing 1:

A small metal structure (possibly a pump house) is located in the southern area of the site (refer

Figure 9);

Figure 9: Small metal structure in southern area

Metal was observed sticking out of the ground in the southern area of the site (Figure 10);

Figure 10: Metal sticking out of the ground surface

Along the southern boundary fence line, and particularly in the south-western corner of the site,

bricks, metal and cobbles were visible on the ground surface. This area appears to be filling

associated with a low filling platform (in the order of 0.5 m in height) for the adjacent allotment to

the south (refer Figure 11);

8. Conceptual Site Model

A Conceptual Site Model (CSM) has been prepared for the investigation area with reference to the

National Environment Protection (Assessment of Site Contamination) Measure 1999 amended 2013

(NEPC 2013) Schedule B2 (Ref 2). The CSM identifies potential contaminant sources and

contaminants of concern, contaminant release mechanisms, exposure pathways and potential

receptors.

9. Field Work Methods

9.1 Sampling Rationale

Potential sources of site contamination identified in the site history comprised imported filling (source

unknown), possible pesticides use / storage on-site, demolition of former structures, opportunistic

dumping and effluent disposal. A preliminary targeted site investigation was conducted to investigate

these sources of potential contamination.

9.2 Methods

The field work was conducted on 6 and 7 November 2018 and included the following:

Walkover assessment by a senior engineer from DP;

Drilling of ten (10) test bores (Bores 1 to 10); and

Dynamic penetrometer tests (cone tip) at Bores 1 to 9 to depths of up to 1.95 m.

The approximate location of the bores is shown on Drawing 1 in Appendix D. The bores were setout

by a geotechnical officer using a hand held GPS, which is accurate to about 10 m depending on

satellite coverage. The approximate coordinates for the bores are shown on the borehole logs.

The bores were drilled using a truck mounted DT100 drilling rig fitted with solid flight augers. Standard

penetrometer testing (SPT) was undertaken a regular depth intervals in the bores.

Soil samples were collected from the bores at regular depth intervals for identification purposes and

possible laboratory testing. The general sampling procedure comprised:

Decontamination of all sampling equipment (where used) using a 3% solution of phosphate free

detergent (Decon 90) and tap water prior to collecting each sample;

The use of new disposable gloves for each sampling event;

Transfer of samples into laboratory-prepared jars and capping immediately;

Collection of replicate samples for Quality Assurance / Quality Control (QA / QC) purposes;

Collection of replicate soil samples in zip-lock plastic bags at each depth for Photo-ionisation

Detector (PID) screening;

Labelling of sample containers with individual and unique identification, including project number,

sample location and sample depth;

Placement of the sample jars and replicate sample bags into a cooled, insulated and sealed

container with ice for transport to the laboratory; and

Use of chain of custody (C-O-C) documentation ensuring that sample tracking and custody could

be cross-checked at any point in the transfer of samples from the field to the laboratory. Copies of

the completed forms are provided in Appendix C.

Replicate samples collected in zip-lock bags were screened for the presence of volatile organic

compounds (VOCs) using a calibrated MiniRAE Lite PID, with a 10.6 eV lamp, calibrated to 100 ppm

Isobutylene.

Following completion of drilling, all bores were reinstated using excavated spoil, which was compacted

using the excavation/drilling equipment and manual tamping.

9.3 Data Quality Objectives (DQOs)

The scope of the PSI was devised generally in accordance with the seven step data quality objective

(DQO) process, as documented in Appendix B, Schedule B2, National Environmental Protection

Council (NEPC) National Environmental Protection (Assessment of Site Contamination) Measure 2013

(NEPC 2013). The DQO process is outlined in Table 7.

Page 25: Proposed Service Centre · 2020-02-03 · Preliminary Site Investigation for Contamination, Proposed Service Centre 91401.00.R.001.Rev0 37 - 41 Bengal Street, Coolongolook December

Table 7: Data Quality Objectives

DQO Achievement Evaluation Procedure

Step 1 – State the problem Possible presence, extent and level of contamination

Step 2 – Identify the decision

Assess whether the site is suitable for the intended land use from a

contamination perspective

Refer Section 11 for adopted site assessment criteria

Step 3 - Identify the inputs to the

decision

Site history review from previous investigation

Selection of appropriate contaminants of concern

Field and laboratory QA/QC data to assess the suitability of the

environmental data for the assessment

Step 4 – Define the Boundary of

the Assessment As defined in Section 2 and shown on Drawing 1.

Step 5 – Develop of decision rule

Selected soil samples were analysed for the contaminants of concern as

outlined in Section 8.

The field and laboratory data was assessed as reliable by reference to the

Data Quality Indicators (DQI) as outlined in Step 7.

Step 6 – Specify the acceptance

criteria

The site assessment criteria was developed through reference to NEPC

1999 (amended 2013).

The acceptance limits for laboratory QA/QC parameters were based on the

laboratory reported acceptance limits and those stated in NEPC 1999.

Step 7 – Optimise the design for

obtaining data

Design was optimised by the development of a plan for sample collection,

handling and analysis, including undertaking quality assurance and quality

control measures to allow assessment of the suitability of the data collected.

Measurement to assess the project DQOs using data quality indicators

(DQIs) as follows:

Completeness – completion of field and laboratory chain of custody

documentation, use of experienced field staff, compliance with holding times

and documentation correct

Comparability – consistent sampling procedures, use of NATA certified

laboratory and experienced field staff

Representativeness – appropriate media sampled

Precision - Analysis of field and laboratory replicates and achievement of

acceptable RPDs, acceptable levels for laboratory QC criteria

Accuracy – Analysis of field duplicates, matrix spikes and surrogate spikes

Use of chain of custody documentation for the handling, transport and delivery of samples to the

selected laboratory.

9.4.2 Laboratory QA/QC

The NATA accredited chemical laboratories undertook in-house QA/QC procedures involving the

routine testing of:

Reagent blanks;

Spike recovery analysis;

Laboratory duplicate analysis;

Analysis of control standards;

Calibration standards and blanks; and

Statistical analysis of QC data.

10. Field Work Results

10.1 Subsurface Conditions

The results of the subsurface investigation are shown in the borehole logs report sheets in Appendix

A, together with notes defining classification methods and descriptive terms.

The boreholes encountered relatively uniform conditions over the site. The general subsurface profile

is summarised as follows:

Unit 1.1 (Filling) Generally gravelly silty clay filling. Some anthropogenic inclusions,

such as metal, brick fragments and concrete were observed at the

surface near some of the bores;

Unit 2 (Alluvium) Soft to firm dark brown gravelly clayey silt or stiff silty clay;

Unit 3 (Residual Clay) Hard light grey or brown gravelly clay / silty clay or orange brown

clay;

The results of PID screening on soil samples are shown on the logs in Appendix A. PID screening

suggested the absence of gross volatile hydrocarbon impact (i.e. <1 ppm) in the samples screened.

There was no visual or olfactory evidence (i.e. staining or odours) to suggest the presence of gross

contamination within the soils investigated.

11. Site Assessment Criteria

11.1 Introduction

The proposed development includes the construction of service centre with the majority of the site

covered with pavements. It is understood that earthworks including up to 2 m of cut and fill will be

required for the proposed development.

The assessment and characterisation of the material on the site and the results of laboratory testing have been compared to the following guidelines:

National Environmental Protection Council (NEPC), “National Environmental Protection

(Assessment of Site Contamination) Measures” (NEPM), 1999 (amended 2013) [Ref 4];

NSW EPA, 'Waste Classification Guidelines, Part 1: Classifying Waste', November 2014 [Ref 2];

and

NSW EPA, Resource Recovery Order under Part 9, Clause 93 of the Protection of the

Environment Operations (Waste) Regulation 2014 “The Excavated Natural Material Order 2014”

[Ref 6].

For comparison to the NEPM guidelines, the investigation and screening levels applied in the current

investigation comprise levels adopted for a commercial land use scenarios (HIL-D, HSL-D and

commercial).

11.2 Health Investigation and Screening Levels

The generic health investigation levels (HIL) and health screening levels (HSL) are considered to be

appropriate for the assessment of contamination at the site. The adopted soil HIL and HSL for the

potential contaminants of concern are presented in Table 11.

Page 30: Proposed Service Centre · 2020-02-03 · Preliminary Site Investigation for Contamination, Proposed Service Centre 91401.00.R.001.Rev0 37 - 41 Bengal Street, Coolongolook December

3 The soil saturation concentration (Csat) is defined as the soil concentration at which the porewater phase cannot dissolve any more of an individual chemical. The soil vapour that is in equilibrium with the porewater will be at its maximum. If the derived soil HSL exceeds Csat, a soil vapour source concentration for a petroleum mixture could not exceed a level that would results in the maximum allowable vapour risk for the given scenario. For these scenarios, no HSL is presented for these chemicals and the HSL is shown as ‘not limiting’ or ‘NL’.

4 The HSL have been calculated for a potential vapour intrusion pathway, a conservative sand soil (based on nature of filling) and an assumed depth to contamination of 0 m to <1 .

NC – No Criteria.

As shown in Table 11 the adopted HSLs are predicated on a potential vapour intrusion pathway.

Although possible direct contact pathways are present at the site, and construction worker receptors,

the corresponding HSLs are significantly higher than those for the vapour intrusion pathway and are

therefore not drivers for further assessment and / or remediation. As such the direct contact and

intrusive maintenance worker HSLs have not been listed.

11.3 Ecological Investigation Levels

EIL and Added Contaminant Limits (ACLs), where appropriate, have been derived in NEPC (2013) for

only a short list of contaminants comprising As, Cu, Cr (III), DDT, naphthalene, Ni, Pb and Zn. The

adopted EIL, derived using the Interactive (Excel) Calculation Spreadsheet (Standing Council on

Environment and Water (SCEW) website (http://www.scew.gov.au/node/941)) are shown in the

following Table 12.

11.5 Management Limits

In addition to appropriate consideration and application of the HSL and ESL, there are additional

considerations which reflect the nature and properties of petroleum hydrocarbons, including:

Formation of observable light non-aqueous phase liquids (LNAPL);

Fire and explosion hazards;

Effects on buried infrastructure e.g. penetration of, or damage to, in-ground services.

The adopted management limits from Schedule B1 of NEPC (2013) are shown in the following Table

14.

>C34-C40 (F4) 10000

Notes to Table 14:

# Separate management limits for BTEX and naphthalene are not available hence these have not been subtracted from the relevant fractions to obtain F1 and F2

11.6 Asbestos In Soil

Asbestos only poses a risk to human health when asbestos fibres are made airborne and inhaled. If

asbestos is bound in a matrix such as cement or resin, it is not readily made airborne except through

substantial physical damage. Bonded ACM in sound condition represents a low human health risk,

whilst both Fibrous Asbestos (FA) and Asbestos Fines (AF) materials have the potential to generate,

or be associated with, free asbestos fibres. Consequently, FA and AF must be carefully managed to

prevent the release of asbestos fibres into the air.

A detailed asbestos assessment was not undertaken as part of these works. Therefore the presence

or absence of asbestos at a limit of reporting of 0.1 g/kg has been adopted for this assessment as an

initial screen.

11.7 Waste Classification

The results of chemical testing were also compared against NSW EPA Waste Classification

Guidelines (2014) (Ref 2) for a preliminary assessment of possible off-site disposal options to a

licenced facility.

For potential beneficial reuse, the results of chemical testing were also compared against the NSW

EPA ENM RRO criteria (Ref 6).

Page 33: Proposed Service Centre · 2020-02-03 · Preliminary Site Investigation for Contamination, Proposed Service Centre 91401.00.R.001.Rev0 37 - 41 Bengal Street, Coolongolook December

Page 28 of 36

Report on Preliminary Site Investigation for Contamination 91401.00.R.001.Rev0 Proposed Service Centre, 37 - 41 Bengal Street, Coolongolook December 2019

For assessment of the natural soils for Virgin Excavation Natural Material (VENM) the NSW

Environment Protection Authority (EPA) currently, has not issued any official threshold criteria. In

absence of such criteria, the results were compared against the ENM RRO (Ref 6).

12. Laboratory Testing

Laboratory testing for preliminary waste classification purposes was undertaken by Envirolab Services,

a National Association of Testing Authorities, Australia (NATA) registered laboratory. Analytical

Methods used are shown on the laboratory sheets in Appendix C.

Soil samples were selected for analysis on the basis of the likely presence of contamination, based on

material type, visual or olfactory evidence of possible contamination (i.e. odour or staining), proximity

to a known source of contamination, and whether generally representative of soil/fill conditions.

A total of twelve (12) (including 1 duplicate) were selected for analysis for the following potential contaminants:

Metals (Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Nickel, Zinc, Manganese, Iron);

Total Recoverable Hydrocarbons (TRH), Benzene, Toluene, Ethylbenzene, Xylene (BTEX);

Polycyclic Aromatic Hydrocarbons (PAH);

Polychlorinated Biphenyls (PCBs);

Organochlorine (OCP) and Organophosphate (OPP) Pesticides; and

Asbestos.

The detailed results of chemical analysis on the tested samples are presented in the laboratory report sheets in Appendix C, and are summarised in Table 15 to Table 18 below. Based on a review of the report QC results, it is considered that the laboratory test data obtained are reliable and useable for this assessment.

13. Contamination Assessment

13.1 Contamination Status

A number of additional areas of environmental concern were identified during the assessment which

would warrant additional investigation during a detailed investigation to assist with development of a

remediation action plan, if required. These include the following:

Filling, including rubbish, around the water body in the north-western area of the site;

The area around the existing house and detached shed;

The existing effluent tanks in the north-eastern area of the site;

Filling observed on the surface along the eastern boundary of the site; and

Filling observed on the surface in the south-western corner of the site.

Limited testing within and around these areas of environmental concern returned chemical

concentrations below the adopted site assessment criteria for the intended commercial landuse.

Twelve (12) soil samples (including one field replicate) were analysed for the suite of testing outlined

in Section 12. The results were compared against NEPM for Health Based Investigation / Screening

Levels, Ecological Investigation / Screening Levels, Total Petroleum Hydrocarbon Management Limits

for a commercial land use as discussed in Section11.

All samples tested were below the relevant criteria for:

Health investigation and screening levels;

Environmental investigation levels; and

Total petroleum hydrocarbon management limits.

The laboratory results were generally consistent with the visual and olfactory “screening” that

suggested the absence of gross contamination within the test bores.

Although hazardous building materials (HBM) including asbestos, were not observed within the bores,

owing to the presence of structures on the site there is a risk of HBM in unobserved or untested parts

of the site.

Proposed Service Centre, 37 - 41 Bengal Street, Coolongolook December 2019

13.2 Preliminary Waste Classification

In summary, based on the site historical information, site investigations and preliminary laboratory

testing, the following waste classifications are provided:

Existing Filling

The samples of filling tested returned contaminant concentrations below the maximum permissible

concentrations to be classified as General Solid Waste (GSW).

It is recommended, however, that given the potential areas of environmental concern identified during

the preliminary investigation, additional investigation should be undertaken to confirm this preliminary

waste classification prior to export of material from the site.

Natural Soils

The soil contamination testing within the natural soils returned concentrations within the criteria for

General Solid Waste as defined in the EPA Waste Classification Guidelines (Ref 2). In the absence of

specific guidelines for chemical concentrations for Virgin Excavated Natural Material (VENM), the

results of the testing were compared to the NSW EPA Excavated Natural Material (ENM) order (Ref

6). All natural soil sample results were below the absolute maximum and allowable maximum average

concentration values and therefore the natural soil encountered beneath the filling is likely to be

classified as VENM. This should be confirmed in conjunction with the above-mentioned additional

investigation of the filling.

The use of the natural clay and silt soils as Virgin Excavated Natural Material (VENM) would be

contingent on prior acceptance by the receptor site/relevant authority to receive the material. The

VENM materials should not be mixed/cross contaminated with non-ENM materials (e.g. overlying

filling or anthropogenic inclusions). During construction an inspection regime should include the

following:

Stripping and segregation of the overlying filling over the excavation area;

Inspection of the exposed soils by a geo-environmental engineer to assess for the presence of

material which may affect the VENM classification;

Supplementary laboratory testing of the exposed soils to confirm the suitability for VENM;

Regular inspections and testing during construction to ensure that the excavated materials are

appropriately handled and that material different to those encountered during the investigation are

assessed, if encountered.

Additional assessment will be required in the event that the conditions encountered are different to

those found in this assessment, or if anthropogenic inclusions, staining or odours are observed.

It is noted that the conditions set out in the relevant general Resource Recovery Order are designed to

minimise the risk of potential harm to human health or the environment, however, they do not

guarantee that human health or the environment will not be harmed. The suitability of any exempted

material should be confirmed with respect to the particular use proposed (i.e. areas fit for purpose), as

stated in the relevant exemptions.

Page 34 of 36

Report on Preliminary Site Investigation for Contamination 91401.00.R.001.Rev0

Proposed Service Centre, 37 - 41 Bengal Street, Coolongolook December 2019

During construction an unexpected finds protocol should be implemented for the site to outline how to

handled, assess and dispose of any materials different to those observed during the investigation

which may be encountered during the proposed works.

13.3 Conclusions

The results of the desktop assessment and site inspection indicate that a number of potential

contaminating activities have occurred at the site, such as:

Possible importation of filling within the site, particularly in the area around the existing building

and in the eastern part of the site, as encountered in Bore 6, expected behind the small retaining

walls and observed adjacent to the water body;

Possible asbestos within near surface filling from the demolition of former structures on the site;

Localised dumped filling / opportunistic dumping along water body;

Possible impact from the effluent treatment on the site.

The potential areas of environmental concern were generally localised, as shown on Drawing 1, and

associated with near surface impacts. Limited testing within and around these areas of environmental

concern returned chemical concentrations below the adopted site assessment criteria for the intended

commercial land use. It is recommended, however, that additional investigation is undertaken to

assist with development of a remediation action plan, if required. The further investigation should also

include procurement and review of the planning certificates 10.7 (2 and 5) for the site and revision of

the further investigation scope, if required.

It is suggested that the identified potential areas of environmental concern could be readily addressed

through appropriate additional investigation, and remediation (where required) to render the site

suitable for the intended commercial land use.

No assessment of groundwater was undertaken during the investigation. Given the presence of the

existing service station across the Pacific Highway, which is on the list of contaminated sites, it is

suggested that installation of groundwater wells and testing of the groundwater for potential

hydrocarbon impact should be undertaken.

15. Limitations

Douglas Partners (DP) has prepared this report for this project at 37 – 41 Bengal Street, Coolongolook

with reference to DP’s proposal NCL180321 dated 8 August 2018 and acceptance received from

Galen Property Pty Ltd dated 6 September 2018. The work was carried out under DP’s Conditions of

Engagement. This report is provided for the exclusive use of Galen Property Pty Ltd and Turnbull

Planning International Pty Ltd for this project only and for the purposes as described in the report. It

should not be used by or relied upon for other projects or purposes on the same or other site or by a

third party. Any party so relying upon this report beyond its exclusive use and purpose as stated

above, and without the express written consent of DP, does so entirely at its own risk and without

recourse to DP for any loss or damage. In preparing this report DP has necessarily relied upon

information provided by the client and/or their agents.

The results provided in the report are indicative of the sub-surface conditions on the site only at the

specific sampling and/or testing locations, and then only to the depths investigated and at the time the

work was carried out. Sub-surface conditions can change abruptly due to variable geological

processes and also as a result of human influences. Such changes may occur after DP’s field testing

has been completed.

DP’s advice is based upon the conditions encountered during this investigation. The accuracy of the

advice provided by DP in this report may be affected by undetected variations in ground conditions

across the site between and beyond the sampling and/or testing locations. The advice may also be

limited by budget constraints imposed by others or by site accessibility.

Should evidence of filling of unknown origin be encountered and in particular the presence of building

demolition materials, it should be recognised that there may be some risk that such filling may contain

contaminants and hazardous building materials.

This report must be read in conjunction with all of the attached and should be kept in its entirety

without separation of individual pages or sections. DP cannot be held responsible for interpretations

or conclusions made by others unless they are supported by an expressed statement, interpretation,

outcome or conclusion stated in this report.

This report, or sections from this report, should not be used as part of a specification for a project,

without review and agreement by DP. This is because this report has been written as advice and

opinion rather than instructions for construction.

Asbestos has been not detected by observation and /or by laboratory analysis, either on the surface of

the site, or in filling materials sampled and analysed. Although the sampling plan adopted for this

investigation is considered appropriate to achieve the stated project objectives, there are necessarily

parts of the site that have not been sampled and analysed. This is either due to undetected variations

in ground conditions. It is therefore considered possible that HBM, including asbestos, may be

present in unobserved or untested parts of the site, between and beyond sampling locations, and

hence no warranty can be given that asbestos is not present.

The contents of this report do not constitute formal design components such as are required, by the

Health and Safety Legislation and Regulations, to be included in a Safety Report specifying the

hazards likely to be encountered during construction and the controls required to mitigate risk. This

design process requires risk assessment to be undertaken, with such assessment being dependent

upon factors relating to likelihood of occurrence and consequences of damage to property and to life.

This, in turn, requires project data and analysis presently beyond the knowledge and project role

respectively of DP. DP may be able, however, to assist the client in carrying out a risk assessment of

potential hazards contained in the Comments section of this report, as an extension to the current

scope of works, if so requested, and provided that suitable additional information is made available to

DP. Any such risk assessment would, however, be necessarily restricted to the environmental

components set out in this report and to their application by the project designers to project design,

construction, maintenance and demolition.

Introduction These notes have been provided to amplify DP's report in regard to classification methods, field procedures and the comments section. Not all are necessarily relevant to all reports. DP's reports are based on information gained from limited subsurface excavations and sampling, supplemented by knowledge of local geology and experience. For this reason, they must be regarded as interpretive rather than factual documents, limited to some extent by the scope of information on which they rely. Copyright This report is the property of Douglas Partners Pty Ltd. The report may only be used for the purpose for which it was commissioned and in accordance with the Conditions of Engagement for the commission supplied at the time of proposal. Unauthorised use of this report in any form whatsoever is prohibited. Borehole and Test Pit Logs The borehole and test pit logs presented in this report are an engineering and/or geological interpretation of the subsurface conditions, and their reliability will depend to some extent on frequency of sampling and the method of drilling or excavation. Ideally, continuous undisturbed sampling or core drilling will provide the most reliable assessment, but this is not always practicable or possible to justify on economic grounds. In any case the boreholes and test pits represent only a very small sample of the total subsurface profile. Interpretation of the information and its application to design and construction should therefore take into account the spacing of boreholes or pits, the frequency of sampling, and the possibility of other than 'straight line' variations between the test locations. Groundwater Where groundwater levels are measured in boreholes there are several potential problems, namely: • In low permeability soils groundwater may

enter the hole very slowly or perhaps not at all during the time the hole is left open;

• A localised, perched water table may lead to an erroneous indication of the true water table;

• Water table levels will vary from time to time with seasons or recent weather changes. They may not be the same at the time of construction as are indicated in the report; and

• The use of water or mud as a drilling fluid will mask any groundwater inflow. Water has to be blown out of the hole and drilling mud must first be washed out of the hole if water measurements are to be made.

More reliable measurements can be made by installing standpipes which are read at intervals over several days, or perhaps weeks for low permeability soils. Piezometers, sealed in a particular stratum, may be advisable in low permeability soils or where there may be interference from a perched water table. Reports The report has been prepared by qualified personnel, is based on the information obtained from field and laboratory testing, and has been undertaken to current engineering standards of interpretation and analysis. Where the report has been prepared for a specific design proposal, the information and interpretation may not be relevant if the design proposal is changed. If this happens, DP will be pleased to review the report and the sufficiency of the investigation work. Every care is taken with the report as it relates to interpretation of subsurface conditions, discussion of geotechnical and environmental aspects, and recommendations or suggestions for design and construction. However, DP cannot always anticipate or assume responsibility for: • Unexpected variations in ground conditions.

The potential for this will depend partly on borehole or pit spacing and sampling frequency;

• Changes in policy or interpretations of policy by statutory authorities; or

• The actions of contractors responding to commercial pressures.

If these occur, DP will be pleased to assist with investigations or advice to resolve the matter.

Site Anomalies In the event that conditions encountered on site during construction appear to vary from those which were expected from the information contained in the report, DP requests that it be immediately notified. Most problems are much more readily resolved when conditions are exposed rather than at some later stage, well after the event. Information for Contractual Purposes Where information obtained from this report is provided for tendering purposes, it is recommended that all information, including the written report and discussion, be made available. In circumstances where the discussion or comments section is not relevant to the contractual situation, it may be appropriate to prepare a specially edited document. DP would be pleased to assist in this regard and/or to make additional report copies available for contract purposes at a nominal charge. Site Inspection The company will always be pleased to provide engineering inspection services for geotechnical and environmental aspects of work to which this report is related. This could range from a site visit to confirm that conditions exposed are as expected, to full time engineering presence on site.

Sampling Sampling is carried out during drilling or test pitting to allow engineering examination (and laboratory testing where required) of the soil or rock. Disturbed samples taken during drilling provide information on colour, type, inclusions and, depending upon the degree of disturbance, some information on strength and structure. Undisturbed samples are taken by pushing a thin-walled sample tube into the soil and withdrawing it to obtain a sample of the soil in a relatively undisturbed state. Such samples yield information on structure and strength, and are necessary for laboratory determination of shear strength and compressibility. Undisturbed sampling is generally effective only in cohesive soils. Test Pits Test pits are usually excavated with a backhoe or an excavator, allowing close examination of the in-situ soil if it is safe to enter into the pit. The depth of excavation is limited to about 3 m for a backhoe and up to 6 m for a large excavator. A potential disadvantage of this investigation method is the larger area of disturbance to the site. Large Diameter Augers Boreholes can be drilled using a rotating plate or short spiral auger, generally 300 mm or larger in diameter commonly mounted on a standard piling rig. The cuttings are returned to the surface at intervals (generally not more than 0.5 m) and are disturbed but usually unchanged in moisture content. Identification of soil strata is generally much more reliable than with continuous spiral flight augers, and is usually supplemented by occasional undisturbed tube samples. Continuous Spiral Flight Augers The borehole is advanced using 90-115 mm diameter continuous spiral flight augers which are withdrawn at intervals to allow sampling or in-situ testing. This is a relatively economical means of drilling in clays and sands above the water table. Samples are returned to the surface, or may be collected after withdrawal of the auger flights, but they are disturbed and may be mixed with soils from the sides of the hole. Information from the drilling (as distinct from specific sampling by SPTs or undisturbed samples) is of relatively low

reliability, due to the remoulding, possible mixing or softening of samples by groundwater. Non-core Rotary Drilling The borehole is advanced using a rotary bit, with water or drilling mud being pumped down the drill rods and returned up the annulus, carrying the drill cuttings. Only major changes in stratification can be determined from the cuttings, together with some information from the rate of penetration. Where drilling mud is used this can mask the cuttings and reliable identification is only possible from separate sampling such as SPTs. Continuous Core Drilling A continuous core sample can be obtained using a diamond tipped core barrel, usually with a 50 mm internal diameter. Provided full core recovery is achieved (which is not always possible in weak rocks and granular soils), this technique provides a very reliable method of investigation. Standard Penetration Tests Standard penetration tests (SPT) are used as a means of estimating the density or strength of soils and also of obtaining a relatively undisturbed sample. The test procedure is described in Australian Standard 1289, Methods of Testing Soils for Engineering Purposes - Test 6.3.1. The test is carried out in a borehole by driving a 50 mm diameter split sample tube under the impact of a 63 kg hammer with a free fall of 760 mm. It is normal for the tube to be driven in three successive 150 mm increments and the 'N' value is taken as the number of blows for the last 300 mm. In dense sands, very hard clays or weak rock, the full 450 mm penetration may not be practicable and the test is discontinued. The test results are reported in the following form. • In the case where full penetration is obtained

with successive blow counts for each 150 mm of, say, 4, 6 and 7 as:

4,6,7 N=13

• In the case where the test is discontinued before the full penetration depth, say after 15 blows for the first 150 mm and 30 blows for the next 40 mm as:

15, 30/40 mm

The results of the SPT tests can be related empirically to the engineering properties of the soils. Dynamic Cone Penetrometer Tests / Perth Sand Penetrometer Tests Dynamic penetrometer tests (DCP or PSP) are carried out by driving a steel rod into the ground using a standard weight of hammer falling a specified distance. As the rod penetrates the soil the number of blows required to penetrate each successive 150 mm depth are recorded. Normally there is a depth limitation of 1.2 m, but this may be extended in certain conditions by the use of extension rods. Two types of penetrometer are commonly used. • Perth sand penetrometer - a 16 mm diameter

flat ended rod is driven using a 9 kg hammer dropping 600 mm (AS 1289, Test 6.3.3). This test was developed for testing the density of sands and is mainly used in granular soils and filling.

• Cone penetrometer - a 16 mm diameter rod with a 20 mm diameter cone end is driven using a 9 kg hammer dropping 510 mm (AS 1289, Test 6.3.2). This test was developed initially for pavement subgrade investigations, and correlations of the test results with California Bearing Ratio have been published by various road authorities.

Description and Classification Methods The methods of description and classification of

soils and rocks used in this report are based on

Australian Standard AS 1726-1993, Geotechnical

Site Investigations Code. In general, the

descriptions include strength or density, colour,

structure, soil or rock type and inclusions.

Soil Types Soil types are described according to the

predominant particle size, qualified by the grading

of other particles present:

Type Particle size (mm)

Boulder >200

Cobble 63 - 200

Gravel 2.36 - 63

Sand 0.075 - 2.36

Silt 0.002 - 0.075

Clay <0.002

The sand and gravel sizes can be further

subdivided as follows:

Type Particle size (mm)

Coarse gravel 20 - 63

Medium gravel 6 - 20

Fine gravel 2.36 - 6

Coarse sand 0.6 - 2.36

Medium sand 0.2 - 0.6

Fine sand 0.075 - 0.2

The proportions of secondary constituents of soils

are described as:

Term Proportion Example

And Specify Clay (60%) and

Sand (40%)

Adjective 20 - 35% Sandy Clay

Slightly 12 - 20% Slightly Sandy

Clay

With some 5 - 12% Clay with some

sand

With a trace of 0 - 5% Clay with a trace

of sand

Definitions of grading terms used are:

• Well graded - a good representation of all

particle sizes

• Poorly graded - an excess or deficiency of

particular sizes within the specified range

• Uniformly graded - an excess of a particular

particle size

• Gap graded - a deficiency of a particular

particle size with the range

Cohesive Soils Cohesive soils, such as clays, are classified on the

basis of undrained shear strength. The strength

may be measured by laboratory testing, or

estimated by field tests or engineering

examination. The strength terms are defined as

follows:

Description Abbreviation Undrained shear strength

(kPa)

Very soft vs <12

Soft s 12 - 25

Firm f 25 - 50

Stiff st 50 - 100

Very stiff vst 100 - 200

Hard h >200

Cohesionless Soils Cohesionless soils, such as clean sands, are

classified on the basis of relative density, generally

from the results of standard penetration tests

(SPT), cone penetration tests (CPT) or dynamic

penetrometers (PSP). The relative density terms

are given below:

Relative Density

Abbreviation SPT N value

CPT qc value (MPa)

Very loose vl <4 <2

Loose l 4 - 10 2 -5

Medium

Soil Origin It is often difficult to accurately determine the origin

of a soil. Soils can generally be classified as:

• Residual soil - derived from in-situ weathering

of the underlying rock;

• Transported soils - formed somewhere else

and transported by nature to the site; or

• Filling - moved by man.

Transported soils may be further subdivided into:

• Alluvium - river deposits

• Lacustrine - lake deposits

• Aeolian - wind deposits

• Littoral - beach deposits

• Estuarine - tidal river deposits

• Talus - scree or coarse colluvium

• Slopewash or Colluvium - transported

downslope by gravity assisted by water.

Often includes angular rock fragments and

boulders.

B — Advice provided in accordance with Section 10.7(5)

Please Note: This Council has made no inspection of the property for the purpose of this certificate. Purchasers should satisfy themselves that there are no breaches of the Environmental Planning and Assessment Act 1979 in respect to the use or development of the property.

Additional Matters - General Draft Policy to account for Climate Change Council, at its meeting dated 21/10/2008, adopted as a matter of policy, a draft policy, allowing for sea level rise of 0.9m to the year 2100 with a linear rise over the intervening period. On large subdivisions and rezonings where there is limited impact on adjoining properties, ground levels are to be raised to a level equivalent to the 1% flood level with allowance for climate change to the year 2100. Developments on this land are required to have floors 500mm higher than the 1% flood level. For infill development, floor levels are required to be raised to 500mm above the 1% flood level with allowance for climate change to the year 2060 unless such house raising will have an adverse impact on access, neighbouring properties or the surrounding streetscape. In conjunction with any application involving extensive areas of filling, the applicant is required to submit a flood study to indicate that such filling will not adversely impact on storm flows or flooding in the area. Such studies are to be based on full allowances for climate change. Applications upstream of the river mouth are required to submit a flood study to indicate flood levels including any impacts from climate change to enable assessment by Council officers. For further information, please contact Karen Bee, Planning & Natural Systems division, MidCoast Council on (02) 6591 7222.

Soil samples are extracted with Dichloromethane/Acetone and waters with Dichloromethane and analysed by GC-MS. Benzo(a)pyrene TEQ as per NEPM B1 Guideline on Investigation Levels for Soil and Groundwater - 2013. For soil results:- 1. ‘EQ PQL’values are assuming all contributing PAHs reported as <PQL are actually at the PQL. This is the most conservative approach and can give false positive TEQs given that PAHs that contribute to the TEQ calculation may not be present. 2. ‘EQ zero’values are assuming all contributing PAHs reported as <PQL are zero. This is the least conservative approach and is more susceptible to false negative TEQs when PAHs that contribute to the TEQ calculation are present but below PQL. 3. ‘EQ half PQL’values are assuming all contributing PAHs reported as <PQL are half the stipulated PQL. Hence a mid-point between the most and least conservative approaches above. Note, the Total +ve PAHs PQL is reflective of the lowest individual PQL and is therefore "Total +ve PAHs" is simply a sum of the positive individual PAHs.

Result Definitions

Australian Drinking Water Guidelines recommend that Thermotolerant Coliform, Faecal Enterococci, & E.Coli levels are less than1cfu/100mL. The recommended maximums are taken from "Australian Drinking Water Guidelines", published by NHMRC & ARMC2011.

Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds whichare similar to the analyte of interest, however are not expected to be found in real samples.

Surrogate Spike

This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortifiedwith analytes representative of the analyte class. It is simply a check sample.

LCS (LaboratoryControl Sample)

A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spikeis to monitor the performance of the analytical method used and to determine whether matrix interferencesexist.

Matrix Spike

This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selectedshould be one where the analyte concentration is easily measurable.

Duplicate

This is the component of the analytical signal which is not derived from the sample but from reagents,glassware etc, can be determined by processing solvents and reagents in exactly the same manner as forsamples.

Measurement Uncertainty estimates are available for most tests upon request.

Where sampling dates are not provided, Envirolab are not in a position to comment on the validity of the analysis whererecommended technical holding times may have been breached.

When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis hasproceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon aspracticable.

In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, thesample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols.

Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140% for organics (+/-50% surrogates)and 10-140% for labile SVOCs (including labile surrogates), ultra trace organics and speciated phenols is acceptable.

Duplicates: >10xPQL - RPD acceptance criteria will vary depending on the analytes and the analytical techniques but is typically inthe range 20%-50% – see ELN-P05 QA/QC tables for details; <10xPQL - RPD are higher as the results approach PQL and theestimated measurement uncertainty will statistically increase.

For VOCs in water samples, three vials are required for duplicate or spike analysis.

Spikes for Physical and Aggregate Tests are not applicable.

Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sampleextraction.

Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meetor exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries forthe batch were within the laboratory acceptance criteria.

Acid Extractable Metals in Soil: # Percent recovery is not possible to report due to the high concentration of the element/s in the sample/s. However an acceptable recovery was obtained for the LCS. Asbestos: A portion of the supplied samples were sub-sampled for asbestos analysis according to Envirolab procedures. We cannot guarantee that these sub-samples are indicative of the entire sample. Envirolab recommends supplying 40-50g of sample in its own container. Note: Samples requested for asbestos testing were sub-sampled from jars provided by the client.

Report on Preliminary Site Investigation for Contamination Project 91401.00.R.001.Rev0.QAQC37 – 41 Bengal Street, Coolongolook February 2019

Quality Assurance / Quality Control Assessment Report on Preliminary Site Investigation for Contamination Proposed Service Centre, 37 – 41 Bengal Street, Coolongolook Quality Assurance (QA) was maintained by:

Compliance with a Project Quality Plan written for the objectives of the study;

Using qualified engineers/scientists to undertake the field supervision and sampling;

Following the Douglas Partners Pty Ltd (DP) operating procedures for sampling, field testing and decontamination as presented in Table 1;

Using NATA registered laboratories for sample testing that generally utilise standard laboratory methods of the US EPA, the APHA and NSW EPA.

FPM ENVSAMP Sampling of Contaminated Soils Note to Table 1: From DP Field Procedures Manual Quality Control (QC) of the laboratory programme was achieved by the following means:

Method blanks - the laboratory ran reagent blanks to confirm the equipment and standards used were uncontaminated;

Laboratory replicates - the laboratory split samples internally and conducted tests on separate extracts;

Laboratory spikes - samples were spiked by the laboratory with a known concentration of contaminants and subsequently tested for percent recovery.

Discussion A. Sample Handling and Holding Times A review of the laboratory reports and chain of custody forms associated with the Targeted Contamination Assessment indicates the following:

Samples were received chilled and in good order;

Samples received were appropriately preserved for all tests;

VOC/SVOC samples were received in Teflon sealed containers;

Volatile samples were received with zero headspace;

Samples were received within recommended holding times. B. Method Blanks All method blanks returned results lower than the laboratory detection limit, therefore are acceptable. C. Laboratory Replicates The average RPD for individual contaminants ranged from 0% to 50%. D. Laboratory Spikes Recoveries in the order of 70% to 130% are generally considered to be acceptable for inorganic material and 60% to 140% for organic material. The average percent recovery for individual contaminants ranged from 69% to 130%, which is generally within the quality control objectives. The results should however be qualified and may slightly under-estimate or over-estimate contaminant concentrations in certain samples (ie biased low or high respectively). Conclusions Laboratory replicates were not conducted by the laboratory for this report, however, were analysed at a frequency to meet or exceed NEPM requirements (ie in batches of 20 samples). The duplicate sample (D1 – BH8/0.01) RPD for the batch were within the laboratory acceptance criteria. The accuracy and precision of the soil testing procedures, as inferred by the laboratory QA/QC data is considered to be of sufficient standard to allow the data reported to be used in interpret site contamination conditions.
