4 Executive Summary Environmental Strategies Pty Limited (ES) was commissioned by Prysmian Cables & Systems Australia Pty Ltd (Prysmian) to conduct a Groundwater Monitoring Event (GME) in accordance with the ES (November 2013) Environmental Management Plan (EMP) for a portion of the site known as the coolant leak area located at 1 Heathcote Road, Liverpool NSW (the site). The site location is provided on Figure 1, Appendix A and the site layout in Figure 2, Appendix A. A coolant leak was first identified in February 2012 within Factory 2 of the site with an estimated 10,000 11,000L of coolant (hydrocarbon/water mixture) lost to the subsurface due to a fault that had developed within an in ground concrete pit. Prysmian made a commitment to conduct monthly monitoring of groundwater around the inground pit for an initial three (3) month period with the last event occurring in February The data trends at the end of the three months of monitoring indicated that the groundwater was not impacted by the leaking pit. The NSW EPA voiced concerns that the identified petroleum hydrocarbons in the soil may migrate to underlying groundwater. ES concluded that the hydrocarbons in soil have not impacted underlying groundwater at the time and are unlikely to migrate into the deeper soil profile. Nevertheless, as a due diligence measure, the Remedial Action Plan (RAP) prepared by Prysmian Group (June 2013) recommended that ongoing groundwater monitoring be incorporated into the site s EMP. A less frequent monitoring period was justified and a 12 monthly groundwater monitoring program was adopted. However if groundwater at any time is shown to have been impacted by the contaminants of concern as triggered by the assessment criteria, then contingency options will be assessed. This report presents the results of the 12 monthly GME. The results of the January 2015 GME can be summarised as follows: Groundwater analytical results reported all contaminants of concern (total recoverable hydrocarbons (TRH), benzene, toluene, ethyl benzene, xylenes and naphthalene (BTEXN) below laboratory detection limits and the adopted groundwater acceptance criteria (GAC) Copper and zinc reported concentrations above the GAC. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to pose a risk to human health and the environment and are likely representative of local background levels; and Given that no hydrocarbons were reported above the adopted groundwater criteria, this indicates that groundwater has not been impacted by the leaking coolant tank. Based on the above conclusions, and the results of the ES (June 2013) Supplementary Soil and Groundwater Investigation, ES consider that the coolant leak has not impacted the underlying groundwater and recommends that no further groundwater monitoring (other than that conducted as part of the facility s due diligence) is required.

5 1 Introduction 1.1 Background Environmental Strategies Pty Limited (ES) was commissioned by Prysmian Cables & Systems Australia Pty Ltd (Prysmian) to conduct 12 monthly Groundwater Monitoring Events (GMEs) as specified in an ES (November 2013) Environmental Management Plan (EMP) for a portion of the site known as the coolant leak area located at 1 Heathcote Road, Liverpool NSW (the site). The site location is provided on Figure 1, Appendix A and the site layout in Figure 2, Appendix A. A coolant leak was first identified in February 2012 within Factory 2 of the site with an estimated 10,000 11,000L of coolant (hydrocarbon/water mixture) lost to the subsurface due to a fault that had developed within an in ground concrete pit. Following submission of a pollution incident report and sampling plan by MJM Environmental, Benbow Environmental (BE) were commissioned in July 2012 to undertake an Environmental Site Assessment (ESA) to investigate the extent of the release. Investigations of soil and groundwater were undertaken by Benbow Environmental Pty Ltd (BE) and ES in The results of the BE (January 2013) Environmental Site Assessment and the ES (June 2013) Supplementary Soil and Groundwater Investigation can be summarised as follows: Soil results as reported by BE showed that sample locations 7, 8 and 9 contained contaminant concentrations below health based criteria but exceed the NEPM (2013) Commercial/Industrial Management Limits for coarse soil at depths ranging between 2 and 4.5m below ground level (bgl); Impacted soils are localised to the southern and eastern portion of the in ground pit, between 2 and 4.5m bgl; The results of the ES soil investigation reported no exceedances of hydrocarbons in soil above the adopted criteria (or concentrations above laboratory detection limits) at depths greater than 4.5m bgl; Groundwater analytical results reported all contaminants of concern (TRH, BTEX, PAH and heavy metals) below laboratory reporting limits and the adopted groundwater acceptance criteria (GAC) with the exception of copper and zinc, for which reported concentrations were marginally above the GAC. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to be related to the coolant use/spill. The concentrations of copper and zinc are likely representative of local background levels and are unlikely to pose a risk to human health and the environment; No TRH concentrations were reported above the adopted groundwater criteria indicating that groundwater had not been impacted by the leaking coolant tank; and The soil and groundwater around the tank were considered suitable for the continued commercial/industrial land use. Following the submission of BE (January 2013), ES (June 2013) and a Remedial Action Plan (RAP) prepared by Prysmian (June 2013), the NSW EPA voiced concerns that the identified petroleum hydrocarbons in soil may migrate to underlying groundwater. A letter report was prepared by ES (August 2013) discussing the hydrocarbon impacted soil and its potential to migrate to the underlying groundwater. ES concluded that the hydrocarbons in soil have not impacted underlying groundwater and are unlikely to migrate into the deeper soil profile. Nevertheless, as a due diligence measure, the Remedial Action Prysmian Power Cables & Systems Australia Pty Ltd, January 2015 Groundwater Monitoring Event, 1 Heathcote Road, Liverpool, NSW

6 Plan (RAP) prepared by Prysmian Group (June 2013) recommended that ongoing groundwater monitoring be incorporated into the site s EMP with a contingency plan should groundwater impact be detected from this event in the future. Prysmian made a commitment to conduct monthly monitoring of groundwater around the inground pit for three (3) months. At the end of the three months of monitoring, the data trends indicated that the groundwater was not impacted by the leaking pit. For due diligence measures Prysmian decided that a 12 monthly groundwater monitoring program was justified providing that if groundwater at any time shows to have been impacted by the contaminants of concern as triggered by the assessment criteria, then contingency options will be assessed. This report presents the results of the January 2015 GME. 1.2 Objective Within the original scope provided, the objective of the GME was to: Determine whether groundwater had been impacted from localised leak of coolant and if these impacts, if present, exceeded the adopted human health and environmental criteria or otherwise. 1.3 Scope of Works ES completed the following scope of works: Preparation of a Job Hazard Analysis (JHA); Gauging to depth of water (and light non aqueous phase liquids (LNAPLs) if present) in six (6) monitoring wells; Measurement of field groundwater quality parameters (dissolved oxygen (DO), electrical conductivity (EC), ph, redox potential (Eh) and temperature) of stabilised purged groundwater; Sampling of groundwater from all accessible groundwater monitoring wells using micropurge pump and submitted to NATA accredited laboratory Envirolab for analysis of Total Recoverable Hydrocarbons (TRH C 6 C 40 ), Benzene, Toluene, Ethylbenzene, Xylenes and naphthalene (BTEXN) and Arsenic, Cadmium, Chromium, Copper, Lead, Mercury, Nickel, Zinc (Metals); Collection of Quality Assurance and Quality Control (QA/QC) (collected at a rate of 1:20) including one duplicate, one triplicate and forward these to a NATA accredited laboratory for analysis; Assessment of analytical data against the following guidelines: NEPM (2013) Investigation Levels for Soil and Groundwater; and ANZECC (2000) 95% freshwater guidelines Preparation of a report detailing the findings of the GME. 1.4 Limitations This report is based on the Scope of Work outlined in Section 1.3.

8 2 Site Condition and Surrounding Environment 2.1 Site Identification The site occupies an area of approximately 15.3 hectares and is currently owned by Prysmian. The site location is shown in Figure 1, Appendix A and the site layout at time of sampling is shown in Figure 2 and well locations are presented in Figure 3, Appendix A. Table 2.1 provides a summary of the site details. Result summary tables are included in Appendix B. Table 2.1: Summary of Site Details Characteristic Detail Property Street Address Property Lot / DP Property Local Government Area Property Current Land use Property Area Property Zoning Coordinates for the approximate corners of the subject site (MGA 56) 1 Heathcote Road, Liverpool, NSW Lot 200, DP Liverpool City Council Commercial/Industrial 15.3 Ha Light Industrial (IN2) Easting: Northing: Easting: Northing: Easting: Northing: Easting: Northing: Subject Site Area Approximately 1,120m 2 The property is bounded to the south by Newbridge Road beyond which lies Moorebank Avenue, Georges River to the west, Joyce s Foam products and Bridgewater Business Estate to the east and vacant land to the north. The subject site is bounded by Factory 1 to the west, the centre line of Factory 2 to the east, the access road to the south and the third bay (as specified by the saw tooth roofing panels) of Factory 2 to the North. The subject site area is approximately 1,120m Possible Contaminant Sources on the Site An inspection was limited to Factory 2 (the cable drawing building), refer to Figure 2, Appendix A for site layout. Possible contamination sources in this area included the coolant tank (which was replaced immediately after the leak was notified in February 2012) and the coolant mixture itself (Houghto Draw WD4100) which is stored in drums along the south wall, near to the second entrance door. The composition of the coolant includes several petroleum based compounds and additives and requires dilution with water. The time weighted exposure limit for Houghto Draw WD4100 is listed as 5 mg/m 3.

10 3 Sampling and Analysis Plan and Sampling Methodology This section outlines the methodology adopted by ES during the GME. This section also provides details on the sampling and analysis, description of field equipment used, decontamination procedures, field and laboratory quality assurance and control, laboratory analytical methods and sample preservation. 3.1 Groundwater Groundwater Gauging, Purging and Sampling Groundwater gauging, purging and sampling was completed by ES Environmental Scientist Colin Biggs on 13 th January Samples were collected from the six (6) wells in the vicinity of the reported coolant leak. Refer to Figure 3, Appendix A. Prior to sampling, all wells were gauged with an interface probe to measure groundwater levels and detect the presence of phase separated hydrocarbons (PSH). All monitoring wells were then purged using a peristaltic pump to ensure minimal losses of volatile organic compounds. Water quality parameters recorded included ph, redox potential (Eh), electrical conductivity, dissolved oxygen and temperature. All wells were purged until groundwater parameters stabilised to within 10% of the previous reading. Samples were placed directly into appropriately preserved laboratory supplied sampling containers. The sample for metals analysis was filtered in the field using a 0.45micron millipore filter unit prior to analysis. Disposable tubing was used at each monitoring well and the interface probe was thoroughly decontaminated between gauging events with a phosphate free detergent (Decon 90) and rinsed with potable water. Field records of purging and sampling event are provided in Appendix C Field QA/QC The following procedures were followed during fieldwork to ensure quality control: Water samples were collected in laboratory supplied bottles with Teflon seals; Samples were collected from disposable equipment to prevent cross contamination between sampling locations; Samples were placed in an ice filled esky to keep them below 4 o C in accordance with US EPA SW 846 and AS (2005); and Samples were transferred to the laboratory under a completed chain of custody.

11 4 Field Quality Assurance and Quality Control (QA/QC) 4.1 Chain of Custody Samples were transferred to the laboratory under chain of custody procedures. The details included on the chain of custody forms included the following: Job name and number Date results are required List of samples Preservation method Analysis required Release signature and date Date sampled Acceptance signature and date 4.2 Statement of Duplicate Frequency The following are QA/QC samples were collected for this project: DUP1 and TRIP1 were a groundwater intra laboratory and inter laboratory duplicate of MW1. All RPDs for groundwater were within acceptable ranges as shown in Table 2, Appendix D. Where contaminant concentrations were more than ten times the laboratory limit of reporting, the RPD exceedances were likely to be caused by sample heterogeneity. Furthermore, no elevated RPD value for any primary sample, intra laboratory or inter laboratory sample, exceeded the GAC, and therefore ES considers the elevated RPD values do not affect the validity of the data collected Overall, there is an acceptable level of agreement between original and duplicate samples indicating that field procedures were adequate in obtaining representative samples and minimising the potential for cross contamination. 4.3 Background Sample Results Background samples were not collected as part of this investigation. 4.4 Rinsate Sample Results A rinsate sample was not collected from the final decontamination of the interface probe and purged water bucket. Dedicated sampling materials and best practice sampling methods were adequate to prevent the potential for cross contamination to occur during groundwater sampling. 4.5 Trip Blank Trip Blank samples were not collected as part of this investigation. 4.6 Trip Spike Results Trip Spike samples were not collected as part of this investigation. 4.7 Field Instrument Calibration Field instruments were calibrated prior to use on site.

13 6 Assessment Criteria 6.1 Rationale for Selection of Water Assessment Criteria In accordance with the NEPM (2013) Schedule B(6) The Framework for Risk Based Assessment of Groundwater Contamination it was necessary to determine the relevant environmental values and hence appropriate guideline assessment criteria for the site. To determine the most appropriate groundwater guideline the following environmental values have been considered and are presented in Table 6.1. These have been referenced from Appendix 2 of NSW DEC (2007) Guidelines for the Assessment and Management of Groundwater Contamination and the NEPM (2013) Schedule B (6). Table 6.1 Assessment of Environmental Values Associated with Site Groundwater Environmental Values Aquatic Ecosystems (Freshwater) Human Uses (Drinking Water) Agricultural Use Stock Watering and Irrigation Cultural and Spiritual Values ES Comment The closest surface water receptor is the Georges River located along the western boundary of the site. The Georges River would be classed as a beneficial receptor of groundwater and should be protected. This is classed as a freshwater environment. No registered groundwater bores for domestic use were identified within 500km of the site. EC measurements of the groundwater monitoring bores indicated a TDS <2,000mg/L. This suggests it may be a potable resource and however, given the site is located in a largely industrial based area near to the Georges River it is unlikely a groundwater bore would be installed onsite, or in the vicinity which would produce sufficient yields to warrant abstraction for use. A review of groundwater bore information indicates that superficial groundwater within the area is potentially suitable for either stock watering or irrigation purposes. ES is not aware of any cultural / spiritual values associated with the surface and / or groundwater in this area. Bearing the above in mind, ES consider that for the protection of environmental values the most appropriate guideline values to be applied in relation to the site is the ANZECC (2000) Freshwater Criteria using 95% Limit of Protection and Revised (NEPM) 2013 Assessment of Site Contamination Schedule B(1) Assessment of Groundwater Contamination. Adopted criteria presented in Table 6.2 below lists the adopted groundwater assessment criteria for the site.

15 7 Results The following section presents an overview of the field observations for groundwater encountered during the January 2015 GME. Copies of groundwater sampling field sheets are included in Appendix C. 7.1 Groundwater Gauging Results Groundwater gauging results are summarised below: PSH was not detected in any of the monitoring wells sampled; and Depth to groundwater ranged between 2.105m below top of casing (btoc) at MW2 and 3.891m btoc at MW1. Refer to Table 1 Appendix B for corrected water relative levels (RLs). 7.2 Groundwater Quality Results During sampling the groundwater was observed to be light brown to dark brown in colour, odourless with suspended clay particles. No sheens were observed in any of the purged water. The groundwater field parameters for the site are summarised in Table 7.2 below: Table 7.2: Physiochemical Field Parameters Monitoring well ID Date Temp ( o C) ph ph units Dissolved Oxygen (ppm) Redox/ORP (mv) Conductivity (µs/cm) MW1 13/01/ MW2 13/01/ MW3 13/01/ MW4 13/01/ MW5 13/01/ Unknown (OMW6) 13/01/ Table 7.2 indicates the following groundwater conditions: The temperature of the groundwater ranged from 20.7 to 23.5 o C; ph ranged from 5.03 to 5.69 ph units indicating slightly acidic groundwater conditions; Dissolved oxygen in the groundwater ranged from 0.50 and 2.45 ppm indicating generally aerobic conditions; ORP (oxidation reduction potential) levels measured from 199 to 263mV (using a Ag/AgCl electrode), which indicates oxidising conditions. ORP (or Redox) is a measure of a water system s capacity to either release or gain electrons in chemical reactions. The process of oxidation involves losing electrons while reduction involves gaining electrons; and Conductivity levels were between 297 and 580 (µs/cm), which indicates fresh groundwater conditions.

16 The following presents a summary of results for groundwater samples. Result summary tables are included in Appendix B, with copies of laboratory certificates included in Appendix D. 7.3 Groundwater Analytical Results Heavy Metals Concentrations of heavy metals in all groundwater samples submitted for analysis were reported below the GAC with the exception of: Concentrations of copper in MW4 (3µg/L) and OMW6 (5µg/L); and Concentrations of zinc in all wells sampled BTEXN Concentrations of BTEXN in all groundwater samples submitted for analysis were reported below laboratory detection limits and the adopted GAC TRH Concentrations of TRH in all groundwater samples submitted for analysis were reported below laboratory detection limits and the adopted GAC Discussion The results of this investigation indicate that no detectable petroleum hydrocarbon contamination was present in any of the up gradient or down gradient monitoring well locations above the adopted groundwater acceptance criteria (GAC). However, concentrations of copper and zinc were reported above the GAC. Copper and zinc are ubiquitous within the urban environment and commonly used as a pigment in paints, in metallic structures, electrical wiring, underground services and pipes. It is considered therefore, that the identified groundwater copper and zinc concentrations are potentially the result of long term weathering of metal based paints, metal coatings, metallic structures and pipes in the local urban area, and not necessarily attributable onsite contamination sources i.e associated with the copper drawing process. Furthermore, the site surface is sealed and no potentially pathways to the subsurface were evident at the time of the visit. The recent groundwater monitoring data was compared to that of the previous GME events that occurred in September 2013 and December 2013 and February Table 3 Appendix B shows a comparison of analytical results from these three rounds. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to pose a risk to human health and the environment.

17 8 Conclusions and Recommendations 8.1 Conclusions The following conclusions can be made from the January 2015 GME conducted at the site located at 1 Heathcote Road, Liverpool: Groundwater analytical results reported all contaminants of concern (TRH, and BTEXN) below laboratory detection limits and the adopted groundwater acceptance criteria (GAC) Copper and zinc which reported concentrations above the GAC. ES consider that the concentrations of copper and zinc detected in groundwater are unlikely to pose a risk to human health and the environment and are likely representative of local background levels; No TRH concentrations were reported above the adopted groundwater criteria indicating that groundwater has not been impacted by the leaking coolant tank; and This GME is the fourth monitoring event after the preparation of the RAP and confirms the findings of the ES (June 2013) report, that the groundwater has not been impacted by the leaky coolant tank. 8.2 Recommendations Based on the above conclusions, and the results of the ES (June 2013) Supplementary Soil and Groundwater Investigation, ES consider that the coolant leak has not impacted the underlying groundwater and recommends that no further groundwater monitoring (other than that conducted as part of the facility s due diligence) is required. 8.3 Extent of Uncertainties in the Results The sampling methodologies used by ES during this assessment have been designed to limit uncertainty in the results. ES is confident that the results of this assessment give an accurate representation of the current status of the site but note that in all subsurface investigations the potential remains for variation between sampling points and conditions different from that reported here may exist on site.

48 Client Reference: Prysmian Liverpool Quality Control Definitions Blank: 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 for samples. Duplicate: This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selected should be one where the analyte concentration is easily measurable. Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist. LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortified with analytes representative of the analyte class. It is simply a check sample. Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds which are similar to the analyte of interest, however are not expected to be found in real samples. Laboratory Acceptance Criteria Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries for the batch were within the laboratory acceptance criteria. Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sample extraction. Spikes for Physical and Aggregate Tests are not applicable. For VOCs in water samples, three vials are required for duplicate or spike analysis. Duplicates: <5xPQL - any RPD is acceptable; >5xPQL % RPD is acceptable. Matrix Spikes, LCS and Surrogate recoveries: Generally % for inorganics/metals; % for organics and % for SVOC and speciated phenols is acceptable. In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, the sample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols. When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis has proceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon as practicable. Envirolab Reference: Revision No: R 00 Page 9 of 9
