REMEDIATION ACTION PLAN WARATAH SUPER BATTERY 301 SCENIC DRIVE, DOYALSON, NSW PREPARED FOR GENERATOR PROPERTY MANAGEMENT PTY LTD CES Document Reference: CES170608-GPM-DS

Executive Summary Consulting Earth Scientists Pty Ltd (CES) was commissioned by Generator Property Management Pty Ltd (GPM) to prepare a Remediation Action Plan (RAP) for a portion of the GPM Landholding located at 301 Scenic Drive, Doyalson NSW 2262. The Site is legally described as Part Lot 10 in Deposited Plan (DP) 1201414. Lot 10 DP 1201414 is proposed to be subdivided and two new lots created. The site has been selected for the construction of the Waratah Super Battery by Energy Corporation of NSW (EnergyCo) as a Priority Transmission Infrastructure Project under the Electricity Infrastructure Investment Act 2020. In order to prepare the site for the Waratah Super Battery GPM is required to complete the rehabilitation and demolition works in accordance with its existing approvals. Rehabilitation and demolition works to be completed by GPM include completion of partial demolition and removal for the Coal Handling Plant bunker and backfilling of the residual bunker void, removal of coal residue and other demolition derived materials from the site surface and removal of demolition derived materials stockpiles on the site. To meet the development timeline and meet the requirements of EnergyCo to deliver the Waratah Super Battery prior to the closure of Eraring Power Station GPM has undertaken to obtain a Site Audit Statement which states that the site is suitable for the proposed commercial/industrial land use concurrent with the completion of the site works. The objective of the works undertaken by GPM is to complete the demolition and rehabilitation works at the site and prepare the site for the construction of the Waratah Super Battery, including remediation of the identified demolition caused localised hotspots. The remediation goal is to make the site suitable for the proposed land use, as an 850 MW network standby battery; the Waratah Super Battery, considered to comprise a commercial/industrial land use. CES Report Reference: CES170608-GPM-DS

Page 3 of 121

Based on the Conceptual Site Model, the extent of remediation/management of the following impacts is required to be completed as part of the site preparation works: 

Asbestos: Three localised hotspots of asbestos fines and fibrous asbestos were detected associated with the residual demolition processing of materials on the site surface.



Stockpiled Materials: demolition derived materials near the north-eastern boundary of the site were identified in seven stockpiles (SP1-7): o Asbestos fines and fibrous asbestos associated with the residual demolition processing materials were detected in excess of the adopted human health criteria in samples SP3-5 and SP6-1. o PFAS were detected in stockpiled materials (with the exception of SP1) based on the assessment of results in accordance with Figure 5 of the PFAS NEMP 2.0 (HEPA 2020), materials contained within Stockpiles SP2, SP4, SP5 and SP6 are likely to be suitable for reuse without a detailed risk assessment however SP3 and SP7 require further, more detailed, risk assessment and may require remediation or management to make them suitable for reuse.



AEC 4 PFAS impacted soils: An area of PFAS impacted surface soils were identified in the area of the site referred to as AEC 4, which is likely to be the source of elevated PFAS concentrations in groundwater in that area of the site. Based on the detected soil concentrations and the concentrations in groundwater it is assessed that soil impacts in the AEC 4 area of the site are leaching from near surface soils, migrating through the soil column and impacting groundwater. To address human health and environmental risks and mitigate the elevated concentrations of PFAS in groundwater remediation of PFAS in soils is required in the AEC 4 area of the site.

In addition to the localised hotspots CES (2022a) identified the following: 

The location of disconnected buried services that may contain asbestos has not been determined, and as such there is potential for excavation works onsite to disturb asbestos containing materials. Review of drawing Plan Munmorah Power Station Coal Handling Plant 3.3 kV Cable Route Layout (MM225272B/2 dated 04/02/1965) states that electrical cables for the coal handling plant were direct buried, without potentially asbestos containing conduit. Further work to confirm the details presented in the plan should be undertaken. In addition to the Coal Handling Plant Bunker, there is a potential for asbestos containing conduit to be associated with buried services in the south of the site, where the Coal Stack Amenities building, and other structures were located. Investigation of

CES Report Reference: CES170608-GPM-DS

Page 4 of 121

asbestos containing conduit should be undertaken during removal of concrete slabs, and if encountered the asbestos conduit should be chased out and removed. 

The sum of PFOS and PFHxS concentrations in excess of the adopted human health assessment criteria (recreational use) were detected in groundwater in two discrete areas of the site: in the northern area of the site and in the AEC 4 area of the site. Elevated PFOS in excess of the adopted ecological screening criteria were also detected. Due to the depth to water, the location of the site with respect to groundwater receiving water bodies, and the absence of groundwater extraction these exceedances are unlikely to pose a risk to future site users. The groundwater concentrations are low risk to future site users, and beneficial use of groundwater is considered to be unlikely given the sites hydrogeological setting. The likely source of the PFAS in AEC 4 has been assessed to be impacted near surface soils. Remediation of the PFAS impacted soils in AEC 4 is proposed. The source of impacts in the northern area of the site was assessed to be the offsite former Firefighting Training Area.

The works meet the definition of Category 2 remediation as the works do not meet the definition of a Designated Development under Schedule 3 of Environmental Planning and Assessment Regulation 2000, due to the remediation works requiring disturbance of less than 3 ha of impacted soils and onsite treatment, other than by incineration, and storage of less than 30,000 m3 of contaminated soils. Based on the Remediation Options Assessment, the following option has been selected as suitable: 1. Removal of contaminated media to areas of the GPM Landholding (Asbestos Dumps and Soil Storage Area in the Asbestos Dumps, and the identified near site temporary Storage Area). The approach was selected as the most suitable method of delivering the site in condition suitable for the Waratah Super Battery in a timely manner which meets the project timeline for the Priority Transmission Infrastructure Project. The remediation plan presents details on remediation excavation, material handling and controls, and reinstatement of remediation areas.

CES Report Reference: CES170608-GPM-DS

If the actions prescribed in this RAP are implemented in full during the completion of the site demolition and rehabilitation works, the site will be made suitable for future commercial/industrial land use and should not cause adverse risks to the environment. Early construction works for the Waratah Super Battery (WSB) project within the site may be undertaken in conjunction with ongoing remediation and/or validation works, subject to those works being undertaken outside the identified remediation areas and conducted in a manner that would not result in any direct or indirect impact on the remediation areas, subject to prior confirmation from/agreement with the Site Auditor. Construction works for the WSB project within the remediation areas should only be undertaken once a Site Audit Statement confirms that those areas are suitable for the proposed industrial land use.

INTRODUCTION

Consulting Earth Scientists Pty Ltd (CES) was commissioned by Generator Property Management Pty Ltd (GPM) to prepare a Remediation Action Plan (RAP) for a portion of the GPM Landholding located at 301 Scenic Drive, Doyalson NSW 2262. The Site is legally described as Part Lot 10 in Deposited Plan (DP) 1201414. The lot is proposed to be subdivided and two new lots created. A plan of the proposed new lot is presented in Appendix A. The location and extent of the GPM Landholding is presented as Figure 1. The boundary of the site is presented with a general site layout plan presented as Figure 2. The site has been selected for the construction of the Waratah Super Battery by Energy Corporation of NSW (EnergyCo) as a Priority Transmission Infrastructure Project under the Electricity Infrastructure Investment Act 2020. In order to prepare the site for the Waratah Super Battery GPM is required to complete the rehabilitation and demolition works in accordance with its existing approvals. Rehabilitation and demolition works to be completed by GPM include completion of partial demolition and removal for the Coal Handling Plant bunker and backfilling of the residual bunker void, removal of coal residue and other demolition derived materials from the site surface and removal of demolition derived materials stockpiles on the site. To meet the development timeline and meet the requirements of EnergyCo to deliver the Waratah Super Battery prior to the closure of Eraring Power Station GPM has undertaken to complete the remediation of localised contamination hotspots identified at the site and obtain a Site Audit Statement which states that the site is suitable for the proposed commercial/industrial land use, as required by the developments Infrastructure Appoval (SSI 48492458 dated 21 February 2023). With respect to the remediation required, based on the findings of the Environmental Site Investigation Report Waratah Super Battery Site Former Munmorah Power Station (CES Document Referenced CES170608-GPM-DP dated 10 November 2022), Stockpiled Material CES Report Reference: CES170608-GPM-DS

Assessment Waratah Super Battery Site Former Munmorah Power Station (CES Document Referenced CES170608-GPM-DQ dated 10 November 2022) and Data Gap Investigation Report Waratah Super Battery Site Former Munmorah Power Station (CES Document Referenced CES170608-GPM-DW dated 24 February 2023) the following areas of environmental concern were identified requiring remediation or management: 

Asbestos: Three localised hotspots of asbestos fines and fibrous asbestos were detected associated with the residual demolition processing of materials on the site surface.



Stockpiled Materials: demolition derived materials near the north-eastern boundary of the site were identified in seven stockpiles (SP1-7): o Asbestos fines and fibrous asbestos associated with the residual demolition processing materials were detected in excess of the adopted human health criteria in samples SP3-5 and SP6-1. o PFAS were detected in stockpiled materials (with the exception of SP1) based on the assessment of results in accordance with Figure 5 of the PFAS NEMP 2.0 (HEPA 2020), materials contained within Stockpiles SP2, SP4, SP5 and SP6 are likely to be suitable for reuse without a detailed risk assessment with respect to PFAS however SP3 and SP7 require further, more detailed, risk assessment or may require remediation or management.



The impacts identified by CES (2022) requiring remediation are noted to have arisen from the recent incomplete demolition works only, and not from the site previous use as part of the Munmorah Power Station, with the exception of the AEC 4 PFAS impacts. In addition to the localised hotspots CES (2022a) identified the following: 

that electrical cables for the coal handling plant were direct buried, without potentially asbestos containing conduit. Further work to confirm the details presented in the plan should be undertaken. In addition to the Coal Handling Plant Bunker, there is a potential for asbestos containing conduit to be associated with buried services in the south of the site, where the Coal Stack Amenities building, and other structures were located. Investigation of asbestos containing conduit should be undertaken during removal of concrete slabs, and if encountered the asbestos conduit should be chased out and removed. 

This RAP has been prepared in general accordance with: 

The RAP should be read in conjunction with the reports listed in Section 5. This revision of the RAP presents a material change from the earlier versions of the RAP, due to overall project constraints which has required a deviation from the earlier remediation approach which included retention of a portion of the contaminated materials present onsite to be retained in an engineered cell in accordance with a Long Term Environmental Management Plan. Early construction works for the Waratah Super Battery (WSB) project within the site may be undertaken in conjunction with ongoing remediation and/or validation works, subject to those works being undertaken outside the identified remediation areas and conducted in a manner that would not result in any direct or indirect impact on the remediation areas, subject to prior confirmation from/agreement with the Site Auditor. Construction works for the WSB project within the remediation areas should only be undertaken once a Site Audit Statement confirms that those areas are suitable for the proposed industrial land use.

Site Description

The site area is approximately 13.7 Ha. The site is irregular in shape. The site is vacant and is under care and maintenance by GPM. Care and maintenance works included management of vegetation, erosion and sediment controls and materials stockpiled on the site. From early December 2022 the has been subject to Demolition and Site Restoration works as presented in Section 3.1. Site features, as observed by CES on 08 July 2022 include: • The Coal Stack Area of the site, used during the demolition of the former Munmorah Power Station as a metal processing and load out area, was observed to have small scrap metal pieces distributed across the site surface, ranging in size from small fragments of swarf and dross generated by steel cutting to sections of steel reinforcement up to 0.5 m

CES Report Reference: CES170608-GPM-DS

Page 22 of 121

in length. The metal fragments are widely distributed over the Coal Stack Area where demolition materials were processed, west of the Coal Handling Plant Bunker, however at a low density and frequency. In addition, the historic use of the site for coal stockpiling has resulted in coal fragments visible on the site surface. • Seven stockpiles of demolition derived materials were observed near the north-eastern boundary of the site. • Two dams are located onsite, the Western Settling Basin (near the northwest corner of the site) and the Coal Handling Plant “Clean” Water Pond, near the northern boundary of the site. • No structures are present on the site, with the exception of the former coal handling plant “bunker” which is comprises a long sub-surface concrete structure located in the centre of the Coal Stack Area. The concrete structure extends above the site surface in two locations, at the northern and southern extents of the structure. A ramp from the site surface down to the bunker entrance is located at the northern end of the bunker. • The Perimeter Channel, an open concrete lined surface water management channel is located along the boundary of the former Coal Stack Area. • A shallow unlined dish drain is located along the western boundary, adjacent to the former coal conveyor line. The drain discharges to the western part of the Perimeter Channel and the Western Settling Basin. • Concrete slabs and bunding associated with the bulldozer Above Ground Storage Tanks (ASTs) are located to the south of the site. An oil-water separator remains insitu adjacent to the concrete slabs. • Two concrete slabs are located near the northern boundary of the site, one associated with a former gardeners shed and one a former water tank (understood to have provided fire fighting water storage). • The former Coal Stack and conveyor line areas are sparsely vegetated with grasses and some small bushes/trees, the remaining areas of the site are well vegetated with grasses and established trees. • The site boundary is fenced, in good condition, in all directions with the exception of the north-western boundary, which is partially fenced, and the northern boundary. The site is bound by other GPM held lands, with the exception of the east, which is owned by Snowy Hydro Limited. Current Land Use

The site is under care and maintenance by GPM which includes management of vegetation, erosion and sediment controls and materials stockpiled on the site. The site

is currently subject to works to complete the demolition of the former Munmorah Power Station and preparation for the remediation works. Proposed

Land

Use

The proposed land use is to develop the site to install an 850 MW network standby battery: the Waratah Super Battery. The current design of the development presented in Appendix B and includes: 

Cut/fill operations and site re profiling to create a suitable surface for the construction of battery infrastructure, battery units and switchyard;



Finishing the site surface with a suitable aggregate material in accordance with an engineered specification;



Based on interpolated groundwater contours the inferred groundwater flow direction is generally to the north with some localised variations. Site Hydrology

Run off from the site is likely to be captured by the GPM Landholding stormwater management system which is divided between “Clean” stormwater and “Dirty” water systems. The “Clean” stormwater system typically drains areas of the site which did not contain potentially contaminating activities within the catchment. These areas include landscaped areas, building roofs, roadways, and the buffer lands. The “Clean” stormwater system discharges offsite directly, to the Outlet Canal. The “Dirty” water system is designed to drain those areas of the site where catchment activities have the potential to produce contaminated run off such as the Coal Stack Area, coal conveyor line, and the former firefighting training area (located offsite, partially within the GPM Landholding and partially on lands held by Snowy Hydro Ltd). As such the water in the Coal Stack area and the conveyor line area of the site run off will be collected by the “Dirty” water system and run off from the other areas of the site collected by the “Clean” stormwater system. As noted above the Coal Stack area drains to the “Dirty” water system, via the Perimeter Channel. The Perimeter Channel in the western portion of the Coal Stack area discharges to the Western Settling Basin, and the eastern portion to the offsite Eastern Settling Basin. Similarly, the conveyor area runoff is collected by an unlined dish drain which discharges to the Perimeter Channel, or directly to the Western Settling Basin. The exception to the above is the Coal Handling Plant bunker which discharges to the Coal Grit Sump (offsite) which is likely to overflow to the Station “Clean” stormwater system (offsite). During operations the Coal Grit Sump was pumped back to the Perimeter Channel. The Western Settling Basin, under normal flow conditions also discharges to the Eastern Settling Basin (offsite) via an underground discharge line that discharges to the Perimeter Channel which drains the eastern portion of the Coal Stack area, east of the Coal Handling Plant bunker ramp. The Western Settling Basin has a spillway which discharges to the “Clean” stormwater system in high flow conditions via the S1 Conveyor Pond (offsite) and the offsite Clean Water Channel. The “Clean” stormwater system discharges offsite directly, to the Outlet Canal. As noted above as part of the site development a new stormwater management system will be constructed.

Munmorah Power Station, after which the site was utilised for the storage and handling of coal materials. Following decommissioning of the Munmorah Power Station the site was used during the demolition works as a demolition material processing and load out area. An area to the south of the site was used during the operation of the Munmorah Power Station for the storage of hydrocarbon fuels (diesel) in two ASTs, for the site’s mobile plant. As such, no other potential source of contamination, other than the use of the site for coal storage, hydrocarbon fuel storage and demolition works, has been identified. The site and its surrounds were extensively modified during the construction and operation of the Munmorah Power Station.

Previous Site Use and Activities

The site forms part of the former Munmorah Power Station and its associated surrounding buffer lands. The following activities have been identified to have been undertaken in areas of the site: Coal storage and handling – Storage and handling of solid fuels for the power station was undertaken in the Coal Stack area of the site and the former coal conveyor line area of the site. This process involved moving coal that was delivered to the Coal Stack area by conveyor lines, to and from the Coal Handling plant (which delivered coal to the coal mills located offsite). Coal was moved around the Coal Stockpile area using bulldozers. In addition to mobile plant, this area of the site included fixed plant for the transfer of coal from offsite sources to the power station coal mills (offsite) including the Coal Receiving Hopper and Coal Conveyor system. The Coal Handling Bunker, which remains onsite part of the former coal conveyor system. The Coal Stack area of the site and the former coal conveyor line area comprise approximately 8.2 ha of the site. Mobile Plant Fuelling – The southern corner of the site contained two Above Ground Tanks used to provide diesel fuel to the coal handling mobile plant. Coal Stack amenities and associated buildings – in the vicinity of the Mobile Plant Fuel Storage, five buildings (garage, workers shed, sample crusher house (two) and storeroom) were located. Other areas of the site do not contain areas which were used for a specific process or activity that has been identified to date, with the following exceptions: 

Western Settling Basin and Coal Handling Plant “Clean” Water Pond were used to manage site stormwater.



The former gardeners shed, and green house used as a storage shed for gardening equipment and potentially low volumes of gardening chemicals.



Fire water storage tank used to store a water supply for firefighting activities. Investigations identified that it is unlikely that this tank contained PFAS containing firewater.

The remaining areas of the site appear to have been landscaped and maintained as buffer lands and gardens.

CONCEPTUAL SITE MODEL 6.1

Contaminant Source Information Coal Impacted Soils at Former Coal Handling and Storage Area

Removal of residual coal is covered under existing Development Consent for demolition and site restoration works. Residual coal particles have been identified during previous investigations (CES, 2019c, 2022a) in the Coal Stack area and along the western site boundary, underlying the former coal conveyor line and discrete areas of the adjacent lands. The residual coal material is noted to be distributed on the site surface in a thin discontinuous layer. Coal was also observed in the sediments in the Western Settling Basin during previous investigations (CES, 2019c). Localised areas of elevated TRH concentrations (in excess of the adopted ESL) in the Coal Stack Area and the adjacent lands are also considered to be associated with the presence of coal fragments. With respect to the ESL exceedances the proposed use of the site includes the application of a suitable engineered gravel surface dressing, and as such the site use is not expected to include areas of planting or vegetation. Coal fragments were observed in samples collected from demolition derived material stockpiles SP1, SP2, SP3 (two sample locations), SP4 (one sample location), SP5, SP6 (one sample location) and SP7. Material containing coal fragments may be unsuitable for use at the proposed battery site. Removal of residual coal is included in the scope of work presented in the demolition and site restoration works and is a requirement stipulated by the Waratah Super Battery developer. As such the proposed removal of coal from the site is not considered to be a remedial activity, rather completion of the site demolition and rehabilitation works. The Waratah Super Battery developer has stated that materials with coal fragment content below 10% w/w are suitable retention onsite however based on the current works plan no coal containing materials will be retained onsite. While not considered to be included in the remediation scope, verification of site suitability following removal of the coal fragments is required. Asbestos in Soils and Stockpiled Material The Coal Stack area was used for processing of demolition materials during the power station demolition works.

CES Report Reference: CES170608-GPM-DS

Page 35 of 121

Three localised asbestos (fibrous asbestos containing material and asbestos fibres) hotspots CS108, F9 and H13 were identified during site investigations. The remaining investigation locations did not detect asbestos in soils arising from the demolition works. A further ten locations were identified to have asbestos containing materials on the site surface, however soil sampling did not detect asbestos in soils in excess of the Remediation Acceptance Criteria (refer to Section 8.4). Asbestos fines and fibrous asbestos associated with the residual demolition processing materials were detected in excess of the adopted human health criteria in samples SP3-5 and SP6-1. Remediation or management of the asbestos contamination found in stockpiles 3 (SP3), 6 (SP6) is required during material handling and for potential beneficial reuse. It is a requirement for no asbestos to be present within the top 10cm. In addition, while asbestos concentrations in excess of the adopted human health screening criteria were not detected in SP7, in consideration of the potential for asbestos fibres to be released from the stockpiled materials during materials handling, and appropriate controls and mitigation measures should be implemented. PFAS Impacted Soils, Groundwater, and Stockpiled Materials As identified in the CES (2019a) report, during the demolition works PFAS impacted water was used for dust suppression. Low level PFAS impacts were detected in soil, surface water, sediment and concrete samples collected from all areas of the site, however the concentrations were below SAC. PFAS concentrations in ASLP were also detected generally at low concentrations below the adopted SAC, with the exception of AEC 4 soils. Based on the assessment PFAS in soils are not considered to be a human health or ecological risk, with the exception of localised areas in AEC 4 (refer to Section 6.1.3.3), however in accordance with the PFAS NEMP 2.0 (HEPA 2020) where site soils are considered for re use, assessment is required. In consideration of the concentrations detected, the impacted soils may be suitable for beneficial re use without further assessment of risk. This assessment should be re-considered once the proposed reuse location is identified, to confirm the assessment, and re use is subject to agreement and approval from the regulator. PFAS in Stockpiled Materials PFAS were not detected in excess of the laboratory Practical Quantitation Limit (PQL) in samples collected from SP1, nor in ASLP analysis of the sample collected from SP1, as such SP1 is not considered to be PFAS impacted. CES Report Reference: CES170608-GPM-DS

Page 36 of 121

Based on the assessment of results in accordance with Figure 5 of the PFAS NEMP 2.0 (HEPA 2020), subject to approval and further guidance from the Regulator, material contained in Stockpiles SP2, SP4, SP5 and SP6 may be suitable for beneficial re use without further assessment of risk. This assessment should be re-considered once the proposed reuse location is identified, to confirm the assessment, and re use is subject to agreement and approval from the regulator. Elevated concentrations of PFAS detected in samples analysed by Australian Standard Leaching Procedure (ASLP) from stockpile SP3 and SP7. Based on the leachability of PFAS in SP3 and SP7 remediation or management of the two stockpiles are required. North-eastern Corner of the Site Groundwater investigation results identified that groundwater near the site boundary with of the offsite former Fire Fighter Training Area. Groundwater monitoring wells FB304, FB305, FB306 and FB309 detected PFOS concentrations in excess of the freshwater 95% species protection screening value (NEMP 2.0, HEPA 2020). Elevated PFAS concentrations were not detected in soil samples collected from sampling locations in the north eastern corner of the site. Based on the inferred groundwater flow direction it is likely that the elevated PFAS concentrations in groundwater are migrating offsite to the north of the site. That is to say that the elevated PFAS concentrations in groundwater are migrating through the site in the northern corner of the site. Figure 6 presents the areas of PFAS impacted groundwater and concentrations detected in excess of the screening criteria. With respect to the potential for site operations during and following development to increase the risk of migration and exposure of sensitive receptors to PFAS detected migrating through the site the follow is noted: 

As the PFAS source is located offsite and upgradient, remediation of groundwater is unlikely to permanently reduce the elevated concentrations, and therefore is of limited benefit.



Installation of methods to modify groundwater migration from the offsite source such as cut off walls or similar may modify the site hydrogeological regime resulting in increased PFAS migration.



Groundwater in the north-eastern corner of the site was recorded to be at between 4.8 m and 6.5 m below ground level (groundwater level of between 0.7 to 3.7 m AHD);

CES Report Reference: CES170608-GPM-DS

Page 37 of 121



The proposed development comprises recontouring of the site with a maximum cut of 2 m (in the south west of the site) and no earthworks proposed in the north eastern corner. Following recontouring, the Waratah Super Battery will comprise construction of on grade, within no deep excavations or basements. Localised service trenching will be limited to less that 2 m excavation. As such the development will not require excavation into groundwater requiring dewatering during or following development or which could result in exposure to PFAS in groundwater, mobilisation of PFAS impacts through discharge of pumped groundwater or localised temporary or permanent variation in groundwater flow directions or elevations which could increase or vary the migration of PFAS from the offsite source area.



As discussed in Section 3, the hydrogeological profile of the natural subsurface of the site comprises low permeability soils and rock (coefficient of permeability ranging from 1.1 x 10-6 m/s to 4.7 x 10-9 m/s). where identified, areas of higher permeability (sandy clay soils and sandstone bands in Munmorah Conglomerate) are localised and discontinuous, as a result the geological units as a whole tend towards the lower end of the coefficient of permeability range, which further limits the likelihood of the development introducing an increased risk of PFAS migration or exposure.

Based on the above the PFAS concentrations in the north-eastern corner pose a low risk to human health or the environment onsite during and following development and remediation of PFAS in groundwater in the north-eastern corner of the site is of limited benefit as the source of PFAS in groundwater is located offsite. In addition, with respect to mobilisation and exposure of PFAS in groundwater through groundwater abstraction, the hydraulic characteristics of the shallow aquifer indicates that low yields would be likely, therefore it is unlikely that the development works, or site operations would utilise abstracted groundwater to provide water for dust suppression or irrigation. In consideration of the above details, noting the characterisation and remediation of the offsite PFAS source is likely to be completed in the future, no ongoing management of PFAS in groundwater in the north-eastern corner of the site is required. AEC 4 Elevated PFOS and Sum of PFOS and PFHxS concentrations were detected in wells installed in the AEC 4 area of the site. Figure 6 presents the areas of PFAS impacted groundwater and concentrations detected in excess of the screening criteria. Detection of PFAS in the AEC 4 area of the site, located up hydraulic gradient of, and some distance away from, the former firefighting training area, and other known secondary source CES Report Reference: CES170608-GPM-DS

points or migration pathways may indicate a low-level localised source of PFAS impact. Based on the site history, it is possible that AFFF was used in this area of the site to manage a fire incident associated with the former ASTs. Given the location of AEC 4, the direction of groundwater flow, there is a low risk of PFAS concentrations detected in AEC 4 groundwater from migration offsite. PFAS results for soil samples from AEC 4 reported three exceedances of adopted ecological indirect exposure criteria for PFOS were reported at three locations (A4435 0.0-0.05, A4439 0.0-0.05, and A4446 0.1-0.15) in the surface soils. A4446 0.1-0.15 m detected PFOS in ASLP concentrations of 0.48 µg/L and A4443 1.5-1.6 m which detected PFOS in ASLP concentration of 0.19 µg/L in excess of the interim marine 95% species protection criteria of 0.13 µg/L. Sum PFAS (n=28) concentrations in AEC 4 ranged from <0.1 µg/kg to 38.9 µg/kg in A446 0.1-0.15 m, the mean, standard deviation and 95% Upper Confidence Limit (95% UCL) were 7.00 µg/kg, 9.41 µg/kg and 14.04 µg/kg respectively. For the remaining areas of Waratah Super Battery Site, the Sum PFAS (n=28) concentrations in soils ranged from <0.1 to 13.2 µg/kg, the mean, standard deviation and 95% Upper Confidence Limit (95% UCL) were 1.13 µg/kg, 2.28 µg/kg and 2.63 µg/kg respectively. Comparison between the AEC 4 area concentrations and the wider Waratah Super Battery site concentrations indicate that the AEC 4 area of the site was likely the location of an additional release of PFAS, different from the impacts associated with dust suppression irrigation with PFAS impacted water, and as such the concentrations detected in groundwater in AEC 4 were likely to be a result of a localised source. Higher Sum PFAS (n=28) concentrations were detected in near surface soils, in comparison to samples collected at greater depths in the soil column, indicative of a surface release combined with vertical migration through the soil column, impacting soils and underlying groundwater. Sum PFAS (n=28) concentrations in shallow samples (<0.5 m) ranged from <0.1 to 35.9 µg/kg, the mean, standard deviation and 95% Upper Confidence Limit (95% UCL) were 8.28 µg/kg, 10.6 µg/kg and 17.52 µg/kg respectively while Sum PFAS (n=28) concentrations in deeper soils (>0.5 m) ranged from 0.5 to 10.6 µg/kg, the mean, standard deviation and 95% Upper Confidence Limit (95% UCL) were 3.47 µg/kg, 3.02 µg/kg and 5.34 µg/kg respectively.

Groundwater PFOS concentrations ranged from 0.013 µg/L in well FI211 to 1.3 µg/L in well A4435. Four groundwater exceedances (AEC4-MW03, A4407, A4435, and A4439) of adopted PFAS NEMP 2.0 interim marine 95% species protection criteria and three exceedances (AEC4MW03, A4435 and A4439) of adopted Guidelines for Managing Risk in Recreational Water (NHMRC, Updated September 2022) were detected. Upgradient well (FI211) reported the majority of PFAS concentrations were detected marginally above or below the laboratory limit of detection. Highest PFAS concentrations reported in groundwater at A4435 and A4439 where elevated PFOS concentrations were detected in surface soils, which may indicate the source of the elevated groundwater detections is located in the vicinity of A4435 and A4439. The highest concentration of PFOS in ASLP was detected at location A4446, approximately 10 m upgradient from well A4435. Low concentrations detected in well FI211 indicate that the PFAS source is localised to the AEC 4 area of the site, where the soil investigation has been undertaken. Based on the detected soil concentrations and the concentrations in groundwater it is likely that soil impacts in the AEC 4 area of the site are leaching from near surface soils, migrating through the soil column and impacting groundwater. To mitigate the elevated concentrations of PFAS in groundwater and elevated concentrations of PFAS remediation of PFAS in soils is required in the AEC 4 area of the site. With respect to groundwater concentrations, the following is noted: Based on the soil investigation results, as summarised above, PFAS impacted near surface soils in AEC 4 have been identified as requiring remediation. Remediation of PFAS concentrations in the near surface soils will also address the concentrations of PFAS in groundwater in the AEC 4 area of the site, by removal of the ongoing secondary source. The primary source being the use of PFAS onsite, which has previously ceased. As the proposed remediation extent is unlikely to extend through the entire soil profile (based on validation samples), it is likely that limited residual PFAS will be retained onsite adsorbed to the retained soil column and in pore water, however the proposed remediation is anticipated to remove the majority of PFAS mass within the source area. It is likely that following ongoing source removal the concentrations of PFAS in groundwater at AEC 4 will attenuate over time. CES Report Reference: CES170608-GPM-DS

As with the northeast corner of the site groundwater in the AEC 4 area is between 3.8 m and 4.8 m below ground level (groundwater levels between 12.2 and 12.7 m AHD), with a cut of less than 1 m to a final surface level of between 14.8 to 16.2 m AHD proposed in this area of the site. As noted in Section 6.1.3.2 the development will not require excavation into groundwater requiring dewatering during or following development or which could result in exposure to PFAS in groundwater, mobilisation of PFAS impacts through discharge of pumped groundwater or localised temporary or permanent variation in groundwater flow directions or elevations which could increase or vary the migration of PFAS. The elevated PFAS concentrations in groundwater at AEC 4 are located approximately 340 m from the site boundary in the direction of groundwater flow, based on the inferred groundwater contours (to the north). As noted previously the soils and rock underlying the site are of low permeability, with localised discontinuous bands and lenses of higher permeability materials unlikely to present a preferential migration pathway. Based on the hydraulic characteristics of the site it is unlikely that the PFAS in groundwater in the AEC 4 area of the site will migrate offsite without considerable dilution and attenuation. It is therefore unlikely that the exceedances detected at AEC 4 will migrate offsite. Groundwater sampling of wells installed in as part of site investigations support this assessment, with no exceedances of the adopted screening criteria detected in downgradient sampling points CS106, CS116 and FB301 (located at the downgradient boundary). In addition, based on the comparatively limited disturbance of the site it is unlikely that continuous anthropogenic preferential migration pathways are present in the subsurface. Based on the above discussion the PFAS concentrations in the AEC 4 area of the site pose a low risk to human health or the environment on and offsite during and following development and remediation of PFAS in groundwater in the AEC 4 area of the site is not required beyond secondary source removal. In addition, as noted in Section 6.1.3.2, with respect to mobilisation and exposure of PFAS in groundwater through groundwater abstraction, the hydraulic characteristics of the shallow aquifer indicates that low yields would be likely, therefore it is unlikely that the development works, or site operations would utilise abstracted groundwater to provide water for dust suppression or irrigation. In consideration of the above details no ongoing management of PFAS in groundwater in the AEC 4 area of the site is required.

Residual services/structures underground The demolition works completed to date were limited to above ground structures. Bonded asbestos cement pipe and conduit was used extensively at the former Munmorah Power Station, and as such there is a potential for asbestos containing materials to be located in the sub surface. Intrusive investigations did not encounter or identify any residual services/structures underground containing asbestos. Based on the site history, it is likely that residual buried services are limited to the vicinity of the former coal bunker, coal conveyor lines, and site amenities and structures (in the south of the site). Service penetrations through the concrete retaining wall at the entrance to the former coal bunker were observed during site investigations to be constructed of ACM conduit. The proposed demolition and site restoration works Option 2 include the demolition and removal of structures and services to a minimum of 2 m below ground level, with ACM removed prior to demolition. Review of a recently identified Plan Mummorah Power Station Coal Handling Plant 3.3 kV Cable Route Layout (MM225272B/2 dated 04/02/1965) states that electrical cables for the coal handling plant were direct buried, without potentially asbestos containing conduit. Intrusive investigation should be undertaken to confirm the drawing details. Should investigation confirm the drawing details, no further remediation or management is considered to be required. In addition to the Coal Handling Plant Bunker, there is a potential for asbestos containing conduit to be associated with buried services in the south of the site, where the Coal Stack Amenities building and other structures were located. Investigation of asbestos containing conduit should be undertaken during removal of concrete slabs, and if encountered the asbestos conduit should be chased out and removed. It is noted that ACM conduit service penetrations and weepholes at depths greater than 2 m below final surface level in the Coal Handling Plant Bunker are proposed to be grouted and retained. Given the depth below final surface level, the ACM will be fully encased in concrete and grout filled, this residual asbestos is considered to represent a low risk to future site users and no remediation or no ongoing management is required.

Source Pathway Receptor Linkages

A key concept in the development and application of contamination CSMs is the source – pathway – receptor relationship informed by known and potential sources of contamination, the environmental media impacted by contamination, potential migration and exposure pathways, and the receptors that may be exposed to contamination. In situations where the source – pathway – receptor relationship is incomplete there can be no risk to receptors from contamination, and as a result remediation and/or management is not required. Table 3 presents a summary of CSM including source – pathway – receptor linkages.

REMEDIATION OPTIONS 8.1

Remediation Goal

The remediation goal is to make the site suitable for the proposed land use, as an 850 MW network standby battery; the Waratah Super Battery, considered to comprise a commercial/industrial land use.

8.2

Remediation Options Assessment and Rationale for Selection

In accordance with the Key Principles for the Remediation & Management of Contaminated Sites (Distilled from ANZECC / NHMRC (1992) Australian and New Zealand Guidelines for the Assessment and Management of Contaminated Sites) (NEPC 2013) the preferred hierarchy of options for site clean-up and management are: 1. On-site treatment so that the contaminant is either destroyed or the associated hazard is reduced to an acceptable level; 2. Off-site treatment so that the contaminant is either destroyed or the associated hazard is reduced to an acceptable level, after which the soil is returned to the site; If it is not possible for either of the two above options to be implemented, then other options for consideration should include: a) removal of contaminated soil to an approved site or facility, followed by (where necessary) replacement with clean fill; b) isolation of the contamination on-site in an appropriately designed and managed containment facility; c) a less sensitive land use to minimise the need for remedial works which may include partial remediation; or d) leaving contaminated material in-situ providing there is no immediate danger to the environment or community and the site has appropriate management controls in place. The guidance also considers that: 

Contaminated site management strategies should reflect the need to protect all segments of the environment, both biological and physical (air, land and water, including groundwater). During the assessment and remediation of sites, there should be appropriate controls in place to control emissions to air, land and water.



The fundamental goal of remediation should be to render a site acceptable and safe for long-term continuation of its existing use or proposed use where a change of land use

CES Report Reference: CES170608-GPM-DS

Page 65 of 121

is part of the remediation strategy and maximise to the extent practicable its potential future uses. 

Clean-up should not proceed if the process is likely to create a greater adverse effect than leaving the site undisturbed. This decision would need to be revised in the light of new technologies or clean-up strategies becoming available.



A multi-disciplinary approach is essential to the effective clean-up of contaminated sites.

Consideration must be given to public and occupational health and safety in the development of any strategy to assess, remediate and manage a contaminated site. Site and project specific considerations that have been included in the assessment of remediation options: 

Timing – the site has been selected for the construction of the Waratah Super Battery which has been declared as Priority Transmission Infrastructure Project under the Electricity Infrastructure Investment Act 2020 by the NSW Government. The remediation works are required to be completed to allow for the critical project to be completed. Meeting the timing requirements of the battery project area is a key consideration for the remediation works.



Cost – minimising the cost to the GPM and NSW State Government while delivering sound contamination management.



GPM Landholding – Outside of the site, within the GPM Landholding include areas that have been used previously for the management of power station waste materials including coal ash, unsuitable coal containing materials, asbestos containing materials, other waste materials generated by power station operations, and large concrete structures identified to contain asbestos during the demolition works (for which development consent was granted). As such areas of the GPM Landholding are available and suitable for managing contaminated soils. Two areas of the GPM Landholding that have been identified as relevant to the remediation options appraisal are the Munmorah Asbestos Dumps and the soil storage area in the Asbestos Dumps. Both these areas of the GPM site have been used to deposit waste materials including contaminated soils during the operation of the Munmorah Power Station. In addition, an area the GPM Landholding has been identified as suitable for temporary storage of materials, adjacent to the site. The location and extent of these areas are presented on Figure 4.

CES Report Reference: CES170608-GPM-DS

Page 66 of 121



GPM Landholding Overall Contaminated Land Management Strategy – the management of the GPM Landholding is likely to include large scale remediation of known legacy hydrocarbon and PFAS impacts identified in offsite areas of the Landholding. As part of these future works onsite treatment technologies for PFAS are likely to be available.

A summary of remediation options identified strengths and weakness for each remediation area are presented in Table 6.

Remediation Option Selection

Based on the Remediation Options Assessment, two remediation options have been selected as suitable: 1. Removal of contaminated media to areas of the GPM Landholding (Asbestos Dumps and Soil Storage Area in the Asbestos Dumps, and the identified near site temporary Storage Area). The approach was selected as the most suitable method of delivering the site in condition suitable for the Waratah Super Battery in a timely manner which meets the project timeline.

8.4

Remediation Endpoints

Based on the Remediation Goals and the remediation option selected, specific remediation endpoints applicable to specific contaminants have been defined and are presented in Table 7. Due to the generally low level of contamination detected onsite, the timing constraints on the project, and the specifics of the project site, Remediation Acceptance Criteria have been selected based on conservative Tier 1 screening criteria.

Table 9: General groundwater/surface water Remediation Acceptance Criteria Adopted Guidelines

Rationale Ecological water quality guideline values (EWGVs):

PFAS NEMP 2.0 Ecological water quality guideline values

Relevant surface water receptors comprise the Inlet and Outlet Canals, onsite water management dams and the Tuggerah Lakes, the reported analytical results will be assessed against the Ecological water quality guideline values for freshwater reported in Table 5 of PFAS NEMP 2.0 - 95% species protection – slightly to moderately disturbed systems for the Canals and Tuggerah Lakes and 95% species protection for onsite water management dams. Use of the 95% species protection for PFAS was considered appropriate for use as the receiving water bodies are slightly to moderately disturbed systems.

ANZG (2018) Default Guideline Values

The PFAS NEMP 2.0 (HEPA 2020) notes that for bioaccumulative contaminants, which includes many PFAS, the Water Quality Guideline framework specifies that the 99% species protection DGV [Default Guideline Value] should be used for…assessing bioaccumulation in slightly to moderately disturbed ecosystems, based on the recommendation in ANZG (2018) that the application of the next most protective DGV for contaminants that have the potential to bioaccumulate. The use of the next most protective DGV was not considered to be required as the secondary exposure effects of bioaccumulation and biomagnification have been assessed directly in the Ecological Risk Assessment (Nation Partners 2022), as such the selection of the 95% species protection is consistent with the wider PFAS Assessment underway at the GPM Landholding. For OCPs/OPPs and PCBs, LORs were used as adopted guideline where ANZG (2018) DGV were below LORs.

Human Health Screening Levels ASC NEPM (NEPC 2013)

Health screening levels (HSLs) have been developed for selected petroleum compounds and carbon bands and are applicable to assessing human health risk via the inhalation pathway. Groundwater HSLs are not applicable in conditions where groundwater is less than 2 m below ground level, due to the limitations of the Johnson and Ettinger Model which was used to derive the groundwater HSLs. The site in its current condition does not contain built structures and as such the groundwater HSLs are considered to be appropriate and conservative screening criteria. The HSLs for commercial/industrial land use for sand soil types at depths of 2-4 m below ground level have been adopted as screening criteria

Guidelines for Managing Risk in Recreational Water (NHMRC, 2008)

For the protection of primary and secondary recreational contact, the Guidelines for Managing Risk in Recreational Water (NHMRC, 2008) recommends that the Australian Drinking Water Guidelines Criteria should be adjusted from the consumption of 2 L/day to the consumption of 0.2 L/day.

Offsite Management of Materials in the GPM Landholding

As presented in Table 10, certain material types are proposed to be relocated to other areas of the GPM Landholding due to the material containing coal fragments or to meet final site levels. Possible management options for the materials are discussed below: 

Stockpiles SP1 and SP2 – it is noted that the material contained in SP1 and SP2 do not exceed the adopted human health or ecological adopted remediation acceptance criteria.



Surface residual coal fragments from areas of the site outside of the impacted remediation areas.



Sediments to be excavated from the Coal Handling Plant “Clean” Water Pond and the Western Settling Basin.

With the exception of SP1, however these materials will contain detectable PFAS concentrations and as such will be subject to a re-use assessment in accordance with Section 12 of the PFAS NEMP 2.0 (HEPA 2020) refer to Section 9.7. In addition, to achieve the remediation timeline the following soils will require relocation, management, and storage within the wider GPM site: 

Materials excavated from asbestos hotspots CS108, F9 and H13.



Materials from Stockpile 3.



Material from Stockpiles 4 and 5.



Material from Stockpile 6.



Material from Stockpile 7.



AEC 4 Soils.

Soils from Stockpiles 3 and 7 and excavated soils from AEC 4 comprise PFAS impacted soils and required management in accordance with Section 9.5 and 9.6 when relocated to other offsite areas of the GPM Landholding. Material excavated from Stockpiles 3 and 7 contain asbestos impacts in addition to PFAS concentrations which should be managed in accordance with Section 9.8. Material excavated from asbestos hotspots CS108, F9 and H13 and from Stockpiles 4, 5 and 6 contain detectable PFAS concentrations and as such will be subject to a re-use assessment in accordance with Section 12 of the PFAS NEMP 2.0 (HEPA 2020), refer to Section 9.2. Material excavated from asbestos hotspots CS108, F9 and H13 and Stockpile 6 contain asbestos impacts in addition to detectable PFAS concentrations which should be managed in accordance with Section 9.8.

CES Report Reference: CES170608-GPM-DS

Page 79 of 121

In addition to the above materials, the following materials were assessed as not requiring remediation or management and can be retained onsite, utilised in to fill the Coal Handling Plant bunker void or used in other areas of the GPM Landholding: 

Crushed concrete and aggregate derived from the demolition of the Coal Handling Plant Bunker and the Perimeter Channel.

9.2

Materials Containing Low Levels of PFAS Concentrations

As noted in Section 9.1 materials are proposed to be removed from site due to the material containing coal fragments and to meet site final levels require assessment in accordance with Section 12 of the PFAS NEMP 2.0 (HEPA 2020) prior to re-use. The proposed area of relocation for the soils is presented on Figure 4 as the Soil Storage Area within the Munmorah Asbestos Dumps. The assessment procedure required for reuse of PFAS containing materials without the completion of a detailed risks assessment is presented as Figure 5, Section 12.1 of the PFAS NEMP 2.0 (HEPA 2020). PFAS concentrations in detected in samples of soils for re use are presented in Table 11, with ASLP concentrations presented in Table 12. Soil concentrations do not exceed the applicable human health of ecological based guideline values presented NEPM 2.0 (HEPA 2020). ALSP concentrations do not exceed the Australian Drinking Water Guidelines for PFAS, or the default ecological guideline values for PFAS based on the 95% species protection value for slightly to moderately disturbed ecosystems.

Based on the above assessment, subject to regulatory consultation, in accordance with Section 12.1 Figure 5 (HEPA 2020) the soils should be suitable for re-use without the completion of a detailed risk assessment. This decision tree is noted to be required to be implemented in consultation with the relevant regulator. In consideration of the propose relocation area, Section 12.2 of NEMP 2.0 (HEPA 2020) notes that “Contact with the environmental regulator must be made before any proposal for the following uses is made: 

fill or burial less than 2.0 metres above the seasonal maximum groundwater level



reuse within 200 metres of a surface water body or wetland area



reuse in (or in the vicinity of and able to be transported to) areas which can be identified with any of the nine matters of national environmental significance protected under the EPBC Act, and areas of environmental significance as identified in specific jurisdictions



fill, burial or reuse in locations potentially affected by reasonably foreseeable future rises in groundwater or sea level, or near stormwater drains

CES Report Reference: CES170608-GPM-DS

Page 84 of 121



reuse on agricultural land



reuse as fill in residential developments



reuse as fill on public open space/parkland/recreational land



inclusion in compost, fertilisers or soil conditioners.”

With respect to the above points the following is noted: 

Shallow, near surface groundwater levels at the GPM landholding are likely to be at or near maximum levels resulting the recent extended period of high rainfall. Groundwater levels within the area of proposed filling were recorded to be 0.0 m (B610) to 0.6 m (MW12) below ground level on 18 November 2022.



Ground level and therefore the groundwater level at B610 is noted to have been surveyed to be 4.74 m AHD. The elevation of the Soil Storage Area is approximately 8 m AHD, as a results the soils will not be placed within 2 m of the above the seasonal maximum groundwater level.



Groundwater monitoring results nearby groundwater monitoring wells ranged from 0.03 to 0.14 µg/L (Sum PFAS n=28), as such groundwater concentrations are similar to the ASLP concentrations detected in soils from the Waratah Super Battery site.



The proposed reuse area is not within 200 m of the inundated area of the Munmorah Ash Dam. Ground elevation at well B610 is 4.73 m AHD, which exceeds the full supply level of the Munmorah Ash Dam (4.5 m AHD).



The area is not a wetland. The proposed area is located in an area of the site utilised for waste material storage and containment, including a disposal area for fabric filter bags and asbestos containing materials.



The surface water and sediment sampling from the Munmorah Ash Dam indicate that PFAS concentrations within the material are comparable to those existing in the area of proposed relocation.



The area of the GPM Landholding is not used for agricultural land, residential development, public open space/parkland/recreational land.



As part of the GPM care and maintenance detailed investigation, and formal capping or the Munmorah Asbestos dumps and other waste areas will be required. As result, once completed the materials will be stored in an engineered containment facility with stormwater controls.

Based on the low concentrations detected in the near surface soils form the Waratah Super Battery site, the condition and history of the proposed relocation area (including concentrations of PFAS in sediment, surface water and groundwater), the relocation of the soils form the

CES Report Reference: CES170608-GPM-DS

Page 85 of 121

Waratah Super Battery site as fill is unlikely to impact on the PFAS concentrations in the environment and as such should be acceptable to the environmental regulator. Following placement, a suitable temporary cover/capping should be applied to the material to further reduce the risks of contaminant migration prior to formal capping of these areas of the GPM Landholding.

9.3

Remediation Process

The recommended remediation process is presented in Sections 9.4 to 9.9. Where deviation from the recommended remediation process is required and the deviation will affect the works in such a way as to prevent achieving the remediation endpoints presented in Section 8.4 or prevent the validation of the remediation in accordance with the Validation Plan (refer to Section 10), the prior written agreement of the Site Auditor is required. The sequence of remediation action is to be completed in accordance with project sequencing undertaken by the remediation contractor.

9.4

Site Establishment

Prior to site establishment, all plans, programs, licences, certificates and other documents necessary for the commencement of work will be completed, and Council require to be notified Details on the minimum requirements for Construction Environment Management Plans are presented in Section 11. Site establishment works may include: 

Establishment of site offices, plant storage, decontamination/wash down and maintenance areas, and materials storage area;



Installation of secure fencing (if required) and signage around each remediation area;



Establishment of the plant as required;

9.5

PFAS Impacted Soils and Material

In accordance with the PFAS NEMP 2.0 (HEPA 2020) where PFAS impacted soils and material are stockpiled or stored management is required to ensure that PFAS in soils and material do not pose an unacceptable risk to the environment while stockpiled. Stockpiling, storage and containment of PFAS-contaminated material should be designed with a whole-of-life approach to construction, operation and decommissioning to meet the following essential functional requirements:

CES Report Reference: CES170608-GPM-DS

Page 86 of 121



Avoid, or minimise to the extent practicable, infiltration into the PFAS contaminated materials by precipitation, surface water, and/or groundwater;



Detect, monitor, and collect any PFAS-contaminated liquid (leachate) generated during storage, to be extracted from the sumps for separate treatment or destruction;



Prevent migration into the surrounding soil of leachate from sumps and other collection systems;



Prevent seepage of leachate into groundwater or surface water;



Avoid the release of PFAS impacted sediment as a result of erosion;



Avoid the release of PFASs to the atmosphere;



Mitigate dust generation;



Enable future recovery of stored materials; and



Account for local climatic, fire, flood, geotechnical, and groundwater conditions applicable to the site, property, area and region.

The requirements for stockpiling and storage of materials containing PFAS are presented in Section 10 of the PFAS NEMP 2.0 (HEPA 2020). Stockpiling of PFAS containing soils should be carried out in accordance with the appropriate requirements based on the time frames for the stockpiling presented in Table 6 of the PFAS NEMP 2.0 (HEPA 2020), reproduced in Table 16.

Notes: PFAS-contaminated equipment should be stored under cover on a sturdy impermeable, bunded surface that captures any seepage from equipment and any contaminated stormwater. Equipment, when demonstrated by monitoring to be clean following flushing or rinsing, is not subject to the requirement). PFAS-contaminated liquids should be stored undercover within a secondary containment system so that any leakage due to spills, ruptures, crushing, or mishandling is effectively contained, preventing any release to soil, groundwater, or surface waters. A “first flush” stormwater management system should not be used in conjunction with PFAS storage infrastructure. For further guidance, see Sections 10.2.2, 10.2.3, and 10.3.2.

In addition, the following characteristics of PFAS and requirements for stockpiling should be considered: 



Some PFASs such as fluorotelomer alcohols and ketones are volatile. For these, air emissions need to be considered, noting that the options for air sampling of PFAS are not routine. Management options to reduce volatilization or capture fugitive emissions may need to be considered;

CES Report Reference: CES170608-GPM-DS

Page 88 of 121



Stockpiling, storage, and containment facilities should be designed to ensure they do not spread PFAS contamination or create any pathways for environmental or human health exposure; and



Specific infrastructure and design requirements should be proportionate to the level of risk that is posed by the PFAS-contaminated materials being stored or contained.

9.6

Establish Temporary Storage Area

Based on the selected remedial approach of removal of unsuitable materials from site and relocation of impacted materials to offsite areas of the GPM Landholding, a storage area for PFAS impacted materials prepared in accordance with the PFAS NEMP 2.0 (HEPA 2020) as presented in Section 9.2. Once placed in the temporary storage area the materials are to be managed in accordance with an Environmental Management Plan. A specification for the Storage Area which incorporates the Environmental Management Plan is presented in Appendix D. A summary of the storage area details are presented below: 

Materials will be stored for a “short term” i.e. a maximum of two (2) years.



The storage area should be constructed with a compacted clay base and surrounded by 1 m high compacted clay bunding.



The storage area should be graded to collect leachate and runoff for pump out and treatment/disposal.



Materials should be stockpiled in designated areas based on the material type and source.



Stockpiles should be smoothed with an excavator bucket and covered with anchored low permeability covers (e.g. reinforced polyethylene or equivalent product) to manage PFAS and asbestos risks during storage.



Erosion and sediment controls should be installed around the base of stockpiles.



To minimise the risk of offsite migration of PFAS the Perimeter Channel in the vicinity of the storage area should be modified as a precaution so stormwater discharged from the storage area is diverted to the GPM Landholding “dirty” water system (to the Eastern Settling Basin).



Environmental controls for the storage area are presented in the Environmental Management Plan which identified the roles and responsibilities for management and presents the required management procedures and monitoring and decommissioning of the storage area.

9.7

Remediation Excavations

Remediation excavations should be conducted in the areas identified in Table 4 (Section 6.6) and Figure 3. Validation of remediation areas should be conducted following excavations. The remediation Validation Plan is presented in Section 10. Excavated soils and materials should be handled as little as possible. Excavated impacted soils or material should be (depending on the material characteristics): o Transported offsite to a suitable area of the GPM Landholding that has been prepared for the acceptance of impacted soils or material (such as the GPM Asbestos Dumps and Soil Storage Area or the Temporary Storage Area) o Transported offsite to suitably licenced waste facility capable of accepting the waste (subject to waste classification in accordance with Waste Classification Guidelines: Part 1 Classifying Waste (NSW EPA 2014). Specific considerations for managing PFAS impacted soils and asbestos impacted soils are presented in Sections 9.5 and 9.8.

9.8

Asbestos Impacted Surface Soil and Material

The following controls should be applied to undertake remediation of asbestos impacted surface soils and asbestos impacted stockpiled material: 

A Class A licenced asbestos removal contractor should be commissioned to undertake the asbestos remediation works;



An Asbestos Control Plan should be prepared in accordance with the Safework NSW Asbestos Code of Practice. The Asbestos Control Plan should be prepared with procedures to manage removal of both non friable and friable asbestos;



Prior to asbestos works, the Contractor should notify Safework NSW that asbestos will be removed (using the SafeWork NSW Notification of Asbestos Removal -Application NA-01, or using the electronic notification form online);



Air monitoring during works should be considered. Air monitoring requirements should be in accordance with the requirements of Safework NSW;



During asbestos works control of dust in accordance with the Asbestos Control Plan should be carried out, to minimise the risk of the release of asbestos fibres;



Asbestos impacted soils and material should be maintained in a moist condition during removal, transport and placement works by the application of high-volume lowpressure water.



Asbestos impacted soils and material should be handled a little as possible to minimise the risk of generation of dust with the potential to include inspirable fibres.

CES Report Reference: CES170608-GPM-DS

Page 90 of 121



9.9

If required, where stockpiled materials should be covered with a layer (>200 mm) of unimpacted soils or geotextile, with erosion and sediment controls. Reinstatement

Where required reinstatement of excavated is required the works should be carried out as soon as practicable following confirmation that the remediation end point has been achieved by validation sampling. Timely reinstatement of excavations will minimise the risks associated with excavation stability, work health and safety around open excavations. Reinstatement shall be completed by using material sourced from one (or a combination of two or more) of the following sources: 

VENM that meets the validation plan standards presented in Section 10.8 for imported materials;



General or specific resource recovery material that meets the validation plan standards presented in Section 10.8 for imported materials and the use of the material satisfies the conditions of the general or specific resource recovery exemption; and



Uncontaminated site won material obtained from unimpacted areas from the site (subject to suitability assessment).

Reinstatement filling works should be completed under the supervision of an experienced geotechnical practitioner in accordance with AS 3798-2007 Guidelines on Earthworks for Commercial and Residential Developments or as recommended by the Geotechnical Practitioner to provide engineered fill suitable to facilitate future use for the site and to minimise in so far as practicable infiltration through the fill mass. Cohesive materials should be compacted to a minimum of 95 % standard maximum dry density ratio with a moisture condition ± 2% Optimum Moisture Content, cohesionless soils should be compacted to a minimum density index of 75%, or other standard as prescribed by an experienced geotechnical practitioner. Overly dry or saturated soils which do not meet the moisture specification presented above should be treated to meet the required moisture condition. Treatment could include the addition of water, drying or other treatment methods considered suitable by the geotechnical practitioner. Soils to be used for reinstatement of the excavated areas should be assessed for geotechnical suitability by the geotechnical practitioner. As a minimum the materials should be assessed to

VALIDATION SAMPLING PLAN

The following validation plan should be implemented to demonstrate that remediation endpoints have been achieved. Following completion of the validation sampling, a Validation Report should be prepared in Consultants reporting on contaminated land: Contaminated Land Guidelines (NSW EPA 2020) and submitted to the Site Auditor for review.

10.1

Data Quality Objectives

The DQO process is a seven-step iterative planning approach that is used to define the type, quantity and quality of data needed to inform decisions relating to the objectives of the investigation. Step 1 – State the Problem This step comprises a summary of the environmental impact that will require new environmental data and identifies the resources required to resolve the issue. The problem is: 

Has the remediation end point and therefore remediation goal presented in Section 8.4 and Section 8.1 been achieved?

The objective is to confirm or otherwise that the remediation has been successfully completed. The consultant project team will comprise Tristan Goodbody (Associate Environmental Engineer, Project Manager) with Victor Arias (Senior Environmental Scientist, CENVP:SC) and Chris Rotsides (Environmental Scientist) as the field team. The Sub-contract analytical laboratories are Envirolab (Primary) and ALS (Secondary). The NSW Auditor project team will comprise Kylie Lloyd (NSW EPA Accredited Site Auditor) and Joshua Lloyd (Senior Hydrogeologist). The conceptual site model is presented in Section 6. The remediation plan is presented in Section 9. Step 2 – Identify the Decision Statement This step comprises the identification of decisions that need to be made about the impact and the new environmental data required to make them.

CES Report Reference: CES170608-GPM-DS

Page 93 of 121



What are the concentrations of contaminants in the validation areas?



Do contaminant concentrations exceed the remediation acceptance criteria?



Do contaminant concentrations pose an unacceptable risk to human health or the environment?



Has the remediation end point been achieved?

It is expected that by resolving these questions, it will be possible to resolve the objectives of the project. Step 3 – Identify Inputs to the Decision This step involves the identification of the information required to support any decision and whether any new environmental data will be required. 

Validation sampling results;



Conceptual Site Model (Section 6);



The adopted remediation acceptance criteria are discussed in Section 8.4. Step 4 – Define the Study Boundaries

This step involves the spatial and temporal aspects of the environmental media that the data must represent to support the decision (s). 

Lateral – as defined by the site perimeter shown on Figure 2;



Vertical – as defined by the site surface to the maximum depth of the deepest existing groundwater monitoring well, apprximately 8 m; and



This project involves the collection of spot sampling events at the proposed locations. As a result, the concentrations detected by the laboratory in the samples recovered will be representative of discrete moments in time and as such, will be subject to climatic and anthropogenic activities at that point or related to human activities that have occurred up to that point at the particular sampling location, and therefore may not be representative of long-term concentrations. If average concentrations are required to enable an understanding of longer term (chronic) risks, then additional sampling may be required. Step 5 – Develop the Decision Rule

This step comprises defining the parameter of interest, specifying the action level and integrating Step 1 to 4 into a single statement that gives a logical basis for choosing between alternative actions.

CES Report Reference: CES170608-GPM-DS

Page 94 of 121

For data quality the following decision rule will be adopted; 

The acceptable limits for the QA/QC samples collected during the investigation are presented in Appendix E. A decision on the acceptance of the analytical data will be made on the basis of the Data Quality Indicators (DQI) in the context of the PARCC parameters as follows. o Precision: A quantitative measure of the variability (or reproducibility) of data; o Accuracy: A quantitative measure of the closeness of reported data to the “true” value; o Representativeness: The confidence (expressed qualitatively) that data is representative of each media present on Site; o Completeness: A measure of the amount of useable data from a data collection activity; and o Comparability: The confidence (expressed qualitatively) that data may be considered to be equivalent for each sampling and analytical event.



The parameters of interest are the concentrations in the various sampled media of the contaminants of concern;

The following decision rules are presented: 1. Is the data collected of suitable quality? 2. Do contaminant concentrations exceed the adopted screening criteria? 3. Do contaminant concentrations pose an unacceptable risk to human health or the environment? For the assessment of contaminant concentrations in the following decision rules will be adopted for systematic sampling: 1. Is the 95% Upper Confidence Limit of the arithmetic mean of contaminant concentrations detected in excess of the adopted Tier 1 screening criteria? 2. Is the standard deviation of contaminant concentrations >50% of the adopted Tier 1 screening criteria? 3. Are contaminant concentrations detected in excess of 250% of the adopted Tier 1 screening criteria? 4. Is the mean of contaminant concentrations different from the adopted Tier 1 screening criteria as assessed using null hypothesis significance testing (NHST) at a confidence level of 95%? This assessment is not applicable where contaminant concentrations are not detected above the laboratory Practical Quantitation Limit (PQL). CES Report Reference: CES170608-GPM-DS

Page 95 of 121

5. Do contaminant concentrations pose an unacceptable risk to the receptors identified in the CSM? For the assessment of contaminant concentrations in the following decision rules will be adopted for targeted sampling, where insufficient samples have been collected for statistical analysis or where insufficient numbers of samples have reported concentrations to allow for statistical assessment: 1. Is the mean of contaminant concentrations detected in excess of the adopted Remediation Acceptance Criteria? 2. Do individual sample concentrations exceed the adopted Remediation Acceptance Criteria?

Step 6 – Specify Limits on Decision Errors This step involves specifying the decision-maker’s acceptable limits on decision errors. There are two types of errors: a) The site or decision area is considered not to be contaminated when it actually is – a Type I error. Type I errors can lead to unacceptable risks to human health and the environment, so the regulatory framework is established to protect against Type I errors. b) The site or decision area is considered to be contaminated when it actually is not – a Type II error. Type II errors can lead to sites or decision areas being remediated unnecessarily, or land being used for a less-sensitive land use, or unwarranted restrictions on the surrounding environment. The more severe consequences are with decision error (a) since the risk of jeopardising human health outweighs the consequences of paying more for remediation/management. Step 7 – Optimise the Fieldwork Program Design The optimised program for the validation is presented in Section 10.2 to 10.8.

10.2

Asbestos Impacted Areas

For areas impacted by asbestos the following validation procedure should be carried out. Asbestos impacted areas include: 

CS108, F9 and H13 areas

CES Report Reference: CES170608-GPM-DS

Page 96 of 121



Stockpiles SP3, SP6 and SP7.

Additional areas may include areas where asbestos containing materials are processed or stockpiled during the works. Samples should be field screened in accordance with Section 11.3.2 of ASC NEPM Schedule B2 (NEPC 2013) and analysed for Fibrous Asbestos and Friable Asbestos (AF/FA) (500 ml sample). 

Stockpile footprints less than 200 m2 o 1 sample per 25 m2



Stockpile footprints greater than 200 m2 o In accordance with Table 2 of Contaminated Land Guidelines Sample Design Part 1 Application NSW EPA 2022



For trenches: o One sample from the base of excavation per 5 linear metres with a minimum density of 1 sample per 25 m2; o One sample from walls of excavations should be rate of per 5 m linear metres. Additional samples should be collected from the walls of the excavation where multiple soil types are encountered.



For general excavations less than 200 m2: o The base of the excavation should be sampled at a rate of 1 sample per 25 m2. o The walls of excavations should be rate of 1 sample per 5 m. Additional samples should be collected from the walls of the excavation where multiple soil types are encountered.



For general excavations greater than 200 m2 o In accordance with Table 2 of Contaminated Land Guidelines Sample Design Part 1 Application NSW EPA 2022 o The walls of excavations should be rate of 1 sample per 20 m. Additional samples should be collected from the walls of the excavation where multiple soil types are encountered.

Where excavations are less than 300 mm in depth, sidewall samples are not required. Where excavations are extended to natural soils, visual assessment is considered sufficient for validation of the excavation base, and no sampling is required. Asbestos analysis results will be compared against the remediation acceptance criteria for asbestos.

CES Report Reference: CES170608-GPM-DS

Page 97 of 121

In addition to the sampling above a Clearance Inspection undertaken by a Licenced Asbestos Assessor (LAA) should be undertaken at the completion of the remediation works. Asbestos validation sample locations are presented on Figure 7.

10.3

PFAS Impacted Areas

For areas impacted by PFAS the following validation procedure should be carried out. PFAS impacted areas include: 

Stockpiles SP3 and SP7.



AEC 4 Remediation Area.

Samples should be collected and analysed for PFAS (extended suite) and PFAS in ASLP (short suite). 

CES Report Reference: CES170608-GPM-DS

Page 98 of 121

Where excavations are less than 300 m in depth, sidewall samples are not required. PFAS analysis results will be compared against the remediation acceptance criteria for PFAS impacted soils. PFAS validation sample locations are presented on Figure 8.

10.4

Site Surface Sampling

Removal of residual coal is included in the scope of work presented in the demolition and rehabilitation works and is an engineering requirement stipulated by the Waratah Super Battery developer. As such the proposed removal of coal from the site is not considered to be a remedial activity. Elevated combustible material in excess of the adopted screening criteria was detected in samples of coal fragments collected as part of the site investigation (CES 2022a). To verify that residual coal fragments retained on the site surface do not pose a risk to future site users systematic soil sampling and assessment for Combustible Content and Sulfur content should be completed in accordance with Contaminated Land Guidelines Sample Design Part 1 Application (NSW EPA 2022) over areas of the site where coal containing soils have been identified. A systematic sampling pattern was selected based on 95% confidence level for detecting a circular hotspot 75 m in diameter was selected. The areas of the site where coal fragments were previously identified is presented on Figure 9, which corresponds to an area of 11.6 ha. Using the formulas presented in Appendix C of Contaminated Land Guidelines Sample Design Part 1 Application (NSW EPA 2022) the number of samples required for a square gird is 28 samples with grid spacing of 64 m. It is noted that based on the site shape, a 64 m square grid required 29 sample locations or 2.5 samples per ha. Proposed sample locations are presented on Figure 9. To assess site surface with respect to PFAS concentrations following the remediation, samples should be analysed for PFAS and PFAS in ASLP.

10.5

Waste Classification

The remediation approach has been determined based on limiting the soils required to be transported offsite for disposal. Any contaminated excavated material exported from the site CES Report Reference: CES170608-GPM-DS

Page 99 of 121

must be classified in accordance with NSW EPA (2014) Waste Classification Guidelines: Part 1 Classifying Waste prior to disposal. Waste classification sample rates should be undertaken in accordance with ASC NEPM (NEPC 2013) and Victorian EPA Publication IWRG 702. Samples for waste classification should be analysed for 

10.8

Validation QAQC Plan

The following QAQC plan will be implemented during validation sampling works. Field Quality and Quality Control Procedures Quality assurance procedures adopted for the assessment will include: 1. Ensuring field screening instruments are calibrated; 2. Conducting daily spot checks on calibrated equipment (PID, water quality meter); 3. Ensuring that the procedures and measures listed in Table 1A of the WA DER Interim Guideline on the Assessment and Management of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) are followed; 4. Placing samples immediately on ice following sampling; 5. Ensuring correct sampling containers and preservatives are employed for contaminants being analysed; and 6. Ensuring analysis is performed within recommended holding times. Field Quality Assurance / Quality Control Programme Field QA/QC for this project consists of rinsate samples, blind replicates, split samples and trip blanks. A description of each of these samples and their proposed frequency of testing is provided below. The proposed field and laboratory QA / QC programmes comply with requirements of the PFAS NEMP (HEPA 2018) and ASC NEPM (NEPC 2013) where applicable. Environmental Samples Environmental samples or primary samples are the representative samples of soil, groundwater, surface water, or sediment collected for analysis to determine aspects of their chemical composition. Blind Replicate Samples Blind replicate samples are provided by the collection of two environmental samples from the same location or successively from the same monitoring bore or sample location. These samples are preserved, stored, transported, prepared and analysed in an identical manner. As a minimum, the results of analyses on the blind replicate sample pair are assessed by calculating

CES Report Reference: CES170608-GPM-DS

Page 104 of 121

the Relative Percentage Differences (RPDs) between the results. The RPD is calculated as the difference between the results divided by their mean value and expressed as a percentage. If the RPD exceeds the value adopted for any analytes, additional investigation will be required, or justification provided for not conducting additional investigation. One blind replicate will be collected for every ten environmental samples, in accordance with the requirements of the PFAS NEMP 2.0 (HEPA 2020). This frequency will be sufficient to ensure that each batch of samples is accompanied by a blind replicate. If not, an additional blind replicate will be carried out. Split Samples Split samples provide a check on the analytical proficiency of the laboratories. Split samples are collected from the same location or successively from the same monitoring bore or sample location. Split samples must be taken from the same location as the blind replicate, thus becoming a triplicate sample. Spilt samples (triplicates) are preserved, stored, transported, prepared and analysed, at the secondary laboratory. Split samples will be collected at a rate of one split sample for every 10 environmental samples in accordance with the requirements of the PFAS NEMP 2.0 (HEPA 2020). This frequency will be sufficient to ensure that each batch of samples is accompanied by a split sample. If not, an additional split sample will be carried out. Rinsate Samples Rinsate (equipment) blanks will consist of pre-preserved bottles filled with certified PFAS-free laboratory-prepared deionised water that has been passed over decontaminated field equipment. Rinsate blanks are prepared on site, labelled with a unique CES sample identification number and transported to the principal laboratory for analysis as regular environmental samples. The purpose of the rinsate blank is to assess the efficiency of decontamination procedures. Rinsate blanks will be collected at a rate of one in 10 environmental samples. Rinsate samples are not required if field equipment is dedicated for the specific sampling location. Trip Blanks Trip blanks consisting of pre-washed bottles containing laboratory certified PFAS-free distilled or de-ionised water or uncontaminated soil. The role of trip blanks is to detect potential

CES Report Reference: CES170608-GPM-DS

Page 105 of 121

contamination during sample transport. These samples reside in transport vessels during sampling activities and are not opened in the field. Trip blanks are analysed at the laboratory as regular samples. Trip blanks will be prepared and analysed for each batch presented to the laboratory. Trip Spikes Trip blanks consisting of pre-washed bottles containing laboratory certified PFAS-free distilled or de-ionised water or uncontaminated soil mixed with a known mass of contaminant. The role of trip spike is to detect potential volatile contaminant loss during sample transport. These samples reside in transport vessels during sampling activities and are not opened in the field. Trip spikes are analysed at the laboratory as regular samples. Trip spikes will be prepared and analysed for each batch presented to the laboratory. Sample Handling and Transport Methods All samples will be labelled with a unique identifier consisting of the sample location. Samples will be placed into laboratory prepared and supplied sample containers. After collection, samples will be placed directly into an ice-filled esky and transported to a NATA accredited laboratory for the analytes selected, under chain of custody (COC) protocols.

11.2

Asbestos Control Plan

The Asbestos Control Plan will document specific health and safety requirements associated with the management of asbestos containing material during remediation. The Asbestos Control Plan should be prepared in accordance with the Safework NSW Asbestos Code of Practice. The Asbestos Control Plan should be prepared with procedures to manage removal of both non friable and friable asbestos. The Asbestos Control Plan should provide the methods and management practices to: o Minimise the human health risks associated with the asbestos removal works; o Minimise the volume of asbestos impacted soils and material to be managed or disposed of; Procedures shall include, but not be limited to: a) Documenting the results of the visual and sample assessment and the safe system of management throughout the remediation; b) Wearing appropriate personal protective equipment (PPE); c) Work area air monitoring using air-sampling equipment to monitor airborne asbestos in accordance with Guidance Note on the Membrane Filter Method for Estimating CES Report Reference: CES170608-GPM-DS

Page 109 of 121

Airborne Asbestos Fibres, 2nd Edition (NOHSC:3003, 2005). At a minimum, when friable asbestos is undergoing management, air monitoring for asbestos fibres will be initially performed daily. This may be subject to review following receipt of test results after an initial period, such as one week. The primary objective of the air monitoring programme is to assess the effectiveness of the dust control measures used and provide data on asbestos exposure (if reported); d) Where necessary, appropriate decontamination of trucks that are used to transport contaminated soil before leaving the work site; and e) Control of asbestos during excavation, processing (if required) and placement. Specific health and safety requirements, including appropriate PPE requirements for asbestos sampling, should be documented in the Work Health and Safety Plan and Asbestos Control Plan.

11.3

Materials Handling and Tracking

All materials handling during the remediation works will be tracked by the contractor in order to allow verification of the correct movement and handling. The system will track materials from cradle to grave and will provide detailed information on the location and quantity of all material movements, so that the material being handled can be accounted for. The tracking system shall include accurate tracking of stockpiles through the entire material handling stage and will include confirmation of stockpile locations via registered survey if necessary. A register of all analytical results for stockpiles and excavations will be maintained throughout the remediation works, where analysis is undertaken. Standard forms shall be prepared as part of the Materials Tracking Procedure. The forms and their function shall include, but not be limited to: 

Material Excavation Form – Providing a record of excavated materials for each excavation on the site including the date, material type, excavated quantity and intended destination; and



Material Stockpiling Form – Provides a record of all materials placed in stockpiles. The form will include the date, material type, stockpiled quantity, origin and intended end use.



In the event that off-site disposal is required then an Off-site Transport / Disposal Form will be prepared. This will provide a record of materials removed from the site and including the material type, quantity, origin, shipping destination and an approval by the Environmental Consultant that the material meets the disposal requirements.

CES Report Reference: CES170608-GPM-DS

Page 110 of 121

Off-site Transportation of Material It is the aim of the project to minimise/eliminate off-site disposal of soil. In the first instance efforts will be made to re-apply the material within the site. For material that does require offsite disposal, the offsite disposal documentation must include:     

Waste classification; Waste transporter; Final destination (including POEO licence); Reconciliation of waste dockets with actual disposal volume; and Reconciliation of actual disposal volume and the estimated volume of disposal.

11.4

Noise Control Plan

Noise emissions must be minimised, and work is to be carried out in accordance with the NSW EPA Noise Policy for Industry (2017) for noise emissions from demolition, excavation and construction activities. As noted previously the site is located within the former Munmorah Power Station buffer lands, with the potential of noise to impact sensitive receptors limited, however construction has the potential to be a nuisance to nearby sensitive receptors. Therefore, it will be essential that construction only occurs during hours stipulated within noise regulations. To ensure that noise does not adversely impact on nearby sensitive receptors, the following control measures will be implemented: 

Limit construction operations to the hours stipulated by the Applicable Consent Authority;



In the event that working outside of these hours is required, authorisation should be obtained from the Applicable Consent Authority and communication (letter drop) should be undertaken for all surrounding local residents so that they are advised when work needs to occur out of hours;



Limit reversing movement for trucks or use squawkers rather than reversing beepers;



Fit and maintain appropriate noise attenuation equipment on earthmoving and other vehicles on site;



Ear protection PPE to be available to all employees; and



Site Supervisor to monitor site noise levels should wind conditions direct noise emissions towards residential areas.

Page 111 of 121



Monday to Friday 7 am to 6 pm



Saturday 8 am to 1 pm



No work on Sundays or public holidays



Works outside the hours presented above are allowed provided impacts to surrounding residents are not incurred.

For works outside of Monday to Friday 7 am to 6 pm and Saturday 8 am to 1 pm, noise impacts to surrounding sensitive receptors should be considered. Monitoring of noise impacts to nearby receptors should be included in the Noise Control Plan.

11.5

Dust Control Plan

Dust emissions shall be confined within the site boundary. The following dust control procedures may be employed to comply with this requirement: 

Erection of dust screens around the perimeter of the site;



Securely covering all loads entering or exiting the site;



Use of water sprays across the site to suppress dust;



Covering of all stockpiles of contaminated soil remaining on site more than 24 hours; and



Keeping excavation surfaces moist.

Dust emissions shall also be controlled by ensuring vehicles leave via stabilised site access. Dust will be suppressed at all times. Dusty areas or areas where there is a potential dust emission shall be wet down using fine mist sprays. The excavated material shall be lightly sprayed prior to leaving the site. Where visual inspection indicates that dust levels may be unacceptable, work will cease until measures are taken to reduce emissions or until weather conditions improve. The site supervisor will be responsible for dust management.

11.6

Work Health and Safety Plan

The remediation contractor will develop and implement a suitable Health and Safety Management System in compliance with legislative and regulatory requirements. A sitespecific Work Health and Safety Plan (WHSP) will be developed prior to commencement of the works. The WHSP will detail the appropriate health and safety information necessary to conduct the remediation works in a safe manner.

CES Report Reference: CES170608-GPM-DS

Page 112 of 121

Work Health and Safety Plan The purpose of the site specific WHSP is to provide all relevant health and safety information for all personnel undertaking work at the site and to provide and maintain safety standards and practices which offer the highest practical degree of personal protection to the on-site workers, based on current knowledge. The plan will recognise the legislative obligations of the Contractor and of the Principal and will in particular: a) Recognise that the work to be undertaken as part of the RAP may involve a “construction project” (as defined in the relevant legislation) in respect of which the Principal has obligations as Principal Contractor. These obligations will be expressly dealt with in the plan; and b) Recognise that the work to be undertaken as part of the RAP includes “high risk construction work” (as defined in the relevant legislation) in respect of which both the Contractor and the Principal have obligations. These obligations will be expressly dealt with in the plan. All personnel must read the plan and confirm acceptance of its requirements prior to commencing work at the site. The information provided by the plan shall include: a) Induction requirements; b) Assignment of responsibilities; c) A discussion of site conditions; d) Details of the work; e) Identification of on-site and off-site hazards; f) Assessment of the potential risks associated with identified hazards; g) Procedures to eliminate, or if not possible, control the potential risks; h) Establishment of personnel protection standards and mandatory safety practices and procedures; i) Establishment of WHS monitoring protocols; j) Training and responsibilities of emergency team members; k) Evacuation procedures and emergency drills; l) Emergency information; m) Incident reporting;

CES Report Reference: CES170608-GPM-DS

Page 113 of 121

n) Provision for contingencies that may arise while operations are being conducted during the project; and o) Procedures to ensure that the Contractor consults with, co-operates with, and coordinates its activities with the Principal (and with any other person or entity having concurrent health and safety duties arising out of the remediation works). As a minimum, the works should comply with all legislation, regulations and standards. At a minimum the legislation related to activities that may take place during the remedial works will include: a) NSW 2003, WH&S Amended (Dangerous Goods) Act; b) AS 2436 1981, Guide to Noise Control on Construction, Maintenance and Demolition Sites; c) AS 1470 1986, Health and Safety at Work - Principles and Practices; d) AS 1319 1994, Safety Signs for the Occupational Environment; e) Safe Work Australia 2011, Code of Practice - Excavation Work; f) Workplace Health and Safety Act 2011; and g) Workplace Health and Safety Regulation 2011. The Contractor will be required to assess the level of personal protective equipment (PPE) for personnel working at the site. This may include: a) P2 mask or equivalent respirator; b) Appropriate hazardous material suit; c) Steel capped boots; d) Hard hat; e) Safety vest; and f) Safety glasses (when in an active work zone).

11.7

Community Relations Management Plan

As part of the Munmorah Power Station site rehabilitation, an overarching engagement strategy has been implemented, including a strong focus on community consultation, as demonstrated by the community communications undertaken during the demolition works.

CES Report Reference: CES170608-GPM-DS

Page 114 of 121

The requirements of an additional remediation focused community relations strategy and plan will be determined prior to works commencing and, if required, will be designed by GPM and their appointed community relations consultants Pursuit Communications. GPM currently operate a Community Information & Complaints Line (1800 817 711). Contact persons for the remediation should be appointed by GPM or the remediation contractor, in the interim the appointed contact person is Brooke Simmons of Pursuit Communications (0407 780 710).

11.8

Emergency Response and Unexpected Finds Plan

An Emergency Response and Unexpected Finds (UXF) Plan should be prepared for the works to detail measures to be implemented and actions to be taken during the remediation to manage unexpected finds, unexpected contamination, or incidents not reasonable foreseen. In most cases the unexpected object or substance will be identifiable and familiar to most site workers, however a precautionary approach to any unidentifiable objects/substance will be enforced at the site and the principal of RACER will apply as follows: 

Remove people from within the immediate vicinity of the unidentified object/substance.



Alert other persons in the vicinity to the presence of the unidentified/hazardous object/substance and alert the Site Manager and Environmental Scientist/Occupational Hygienist of the presence of the object/substance.



Confine, cover and isolate the unidentified/hazardous object/substance until a detailed plan of action has been formulated.



Excavate and  Remove object/substance from site once the hazards have been identified and a risk assessment undertaken by the Environmental Scientist/Occupational Hygienist and agreed by the Site Manager. The UXF procedure is presented as Appendix F. Based on the site history, the following potential unexpected finds have been identified: 

Identification of greater than expected volumes of asbestos and asbestos containing materials;



Identification of coal ash deposits and coal ash impacted materials;



Identification of unexpected subsurface structures; and

CES Report Reference: CES170608-GPM-DS

Page 115 of 121



Identification of malodourous/aesthetically unsuitable soils.

11.9

Odour Control Plan

The Odour Control Plan will provide both the requirements for monitoring during the construction works, but also management options to assist with compliance. Odour shall be controlled so that no odours shall be detected at any boundary of the site during remediation works. The following procedures may be employed to comply with this requirement: 

Odour monitoring using an odour diary and/or nasal ranger;



Minimising in so far as practicable the area of impacted soils exposed at a time



Application of fine mist sprays around odorous areas of the site with or without deodorising additives (Zeolite or similar);



Covering of stockpiled materials; and



Application of water foggers or similar.

Assessment of odour emissions from the remediation should be undertake in accordance with the following legislation and guidelines: 

Protection of the Environmental Operations Act 1997;



Protection of the Environment Operations (Clean Air) Regulation 2010;



Approved Methods for the Modelling and Assessment of Air Pollutants in NSW (DEC 2005);



Approved Methods for the Sampling and Analysis of Air Pollutants in NSW (DEC 2007); and



Workplace Exposure Standards for Airborne Contaminants Safework Australia 2019.

12 RECOMMENDATIONS CES considers that if the actions prescribed in this RAP are implemented in full during the completion of the site demolition and rehabilitation works, the site will be made suitable for future commercial/industrial land use and should not cause adverse risks to the environment. Early construction works for the Waratah Super Battery (WSB) project within the site may be undertaken in conjunction with ongoing remediation and/or validation works, subject to those works being undertaken outside the identified remediation areas and conducted in a manner that would not result in any direct or indirect impact on the remediation areas, subject to prior confirmation from/agreement with the Site Auditor. Construction works for the WSB project within the remediation areas should only be undertaken once a Site Audit Statement confirms that those areas are suitable for the proposed industrial land use.

INTRODUCTION

Consulting Earth Scientists Pty Ltd (CES) was commissioned by Generator Property Management Pty Ltd (GPM) to prepare an Environmental Management Plan (EMP) for a temporary stockpile area on a portion of vacant land located within the GPM Landholding. The temporary stockpile area is required to manage PFAS and asbestos impacted soils to be removed from site during the implementation of works required by the Remediation Action Plan, Waratah Super Battery (CES Document Reference CES 170608-GPM-DS). The remediation works have been devised to make the site suitable for the proposed Waratah Super Battery by Energy Corporation of NSW (EnergyCo) which has been identified as a Priority Transmission Infrastructure Project under the Electricity Infrastructure Investment Act 2020. In order to meet the project delivery deadline, temporary stockpiling of impacted materials offsite on an area of vacant land within the GPM Landholding. The Site is legally described as Part Lot 10 in Deposited Plan (DP) 1201414. It is noted that the Waratah Super Battery development proposal includes subdivision of Lot 10 DP 1201414 with new lots created. The site location and the extent of the GPM Landholding is presented on Figure 1. The proposed new lot boundary for the Waratah Super Battery development, the boundary of the site as defined in this EMP, is presented on Figure 2. Based on the investigations undertaken to date and the required remediation extents it is understood that approximately up to 7,980 m3 of PFAS and asbestos impacted materials have been identified and designated to be stored on site for a short-term duration (i.e. maximum two years). This EMP has been prepared with reference to the following:  

REQUIREMENTS OF PFAS IMPACTED MATERIAL STORAGE

Stockpiling, storage and containment of PFAS-contaminated material should be designed with a whole-of-life approach to construction, operation and decommissioning to meet the following essential functional requirements:         

Avoid, or minimise to the extent practicable, infiltration into the PFAS contaminated materials by precipitation, surface water, and/or groundwater; Detect, monitor, and collect any PFAS-contaminated liquid (leachate) generated during storage, to be extracted from the sumps for separate treatment or destruction; Prevent migration into the surrounding soil of leachate from sumps and other collection systems; Prevent seepage of leachate into groundwater or surface water; Avoid the release of PFAS impacted sediment as a result of erosion; Avoid the release of PFASs to the atmosphere; Mitigate dust generation; Enable future recovery of stored materials; and Account for local climatic, fire, flood, geotechnical, and groundwater conditions applicable to the site, property, area and region.

The requirements for stockpiling and storage of materials containing PFAS are presented in Section 10 of the PFAS NEMP 2.0 (HEPA 2020). Stockpiling of PFAS containing soils should be carried out in accordance with the appropriate requirements based on the time frames for the stockpiling presented in Table 6 of the PFAS NEMP 2.0 (HEPA 2020). In addition, the following characteristics of PFAS and requirements for stockpiling should be considered:

CES Document Reference: CES170608-GPR-DZ

CONSULTING EARTH SCIENTISTS



PFAS are capable of long-range transport through the environment, particularly in surface and groundwater, and can migrate through soil and soil-based construction materials. Infiltration through some liners, such as clay and geosynthetic liners, is expected to occur at a significantly slower rate than for other media; Some PFASs such as fluorotelomer alcohols and ketones are volatile. For these, air emissions need to be considered, noting that the options for air sampling of PFAS are not routine. Management options to reduce volatilization or capture fugitive emissions may need to be considered; Stockpiling, storage, and containment facilities should be designed to ensure they do not spread PFAS contamination or create any pathways for environmental or human health exposure; and Specific infrastructure and design requirements should be proportionate to the level of risk that is posed by the PFAS-contaminated materials being stored or contained

This EMP has been prepared to meet the requirements stockpiling for ‘short-term” – 6 months to 2 years.

DOUCUMENT DETAILS OBJECTIVE OF EMP

The objective of the EMP are:  



To ensure that PFAS and asbestos impacted soils are handled in a suitable manner to minimise risks to human health and the environment. To provide specification for containment area material for short-term duration (maximum 2 years) in accordance with the PFAS NEMP 2.0 (HEPA 2020) and Safework NSW (2022) Code of Practice. To contain and manage the 7,980 m3 of impacted material within the constructed containment area and eliminate the risks of contaminant migration through leachate into subsurface soil, groundwater and adjacent areas of the site; and Ensure that leachate is collected within sumps and is appropriately disposed of offsite or destroyed. PERSON(S)RESPONSIBLE FOR IMPLEMENTAION OF EMP

The person(s) responsible for the implementation of the EMP is the GPM Site Manager or their nominated representative.

TIMEFRAME OF EMP The timeframe for the EMP is short term (maximum of 2 years) to be valid for the complete duration of PFAS containment period as identified by the site developer. If storage of material for a period longer than 2 years is required the controls set out in this EMP should be reviewed and revised as required to meet the requirements of PFAS NEMP 2.0 (HEPA 2020) and Safework NSW (2022) Code of Practice or applicable updated guidance which may be in place at the time. The EMP review should be completed before the 2 year period has elapsed. DISTRIBUTION A copy of this EMP, and any revisions of the EMP should be maintained in the GPM site management system and the EMP should be provided to any staff or organisation responsible for managing the stockpiled material, or who carry out works in the stockpile area. PUBLIC NOTIFICATION OF THE EMP Public notification of the EMP is not required. The EMP should be incorporated into the GPM Site Management System and considered in the GPM Landholding Pollution Incident Response Management Plan (PIRMP). TYPE OF EMP This EMP is an active EMP, which requires preparation and ongoing monitoring and maintenance as presented in Section 5. REVIEW OF THE EMP The procedure for review of the EMP is detailed in Section 7.

BACKGROUND AND SETTING

The Storage Area is required to temporarily store and manage impacted soils and materials from the site, which is proposed to be developed as the Waratah Super Battery, an 850 MW network standby battery which has been identified as a Priority Transmission Infrastructure Project under the Electricity Infrastructure Investment Act 2020. A Remediation Action Plan (RAP, Remediation Action Plan, Waratah Super Battery (CES Document Reference CES 170608-GPM-DS)) has been prepared which details the works required to make the site suitable for the proposed development. Due to project time constraints, the preferred remediation strategy was to remove the contaminated soils and material from the site and temporarily store the materials on a prepared area of the GPM Landholding in an environmentally sound manner until a more permanent remediation or management strategy can be devised as part of the GPM strategy for the whole GPM Landholding.

CONTAMINANTS OF CONCERN As identified in Table 1 contaminants of concern identified in the materials are PFAS and Asbestos. A description of the contaminants is presented in the subsequent sections. 3.1.1

PFAS

PFAS are manufactured chemicals that have been used for more than 50 years. PFAS make products non-stick, water repellent, and fire, weather and stain resistant. PFAS have been used in a range of consumer products, such as carpets, clothes and paper, and have also been used in firefighting foams, pesticides and stain repellents. CES Document Reference: CES170608-GPR-DZ

Page 10 of 21

CONSULTING EARTH SCIENTISTS

Stockholm Convention on Persistent Organic Pollutants is a multilateral environmental agreement to protect human health and the environment from persistent organic pollutants. Two large groups of PFAS compounds are listed as persistent organic pollutants (POPs) under the Stockholm Convention: 

PFOS, its salts and perfluorooctane sulfonyl fluoride (PFOSF) were listed in 2009, noting the listing of PFOSF captures a wide range of PFOS-related compounds derived from PFOSF



PFOA, its salts, and PFOA-related compounds were listed in 2019.

The high solubility of PFAS in water means that PFAS may readily leach from soil to surface water and groundwater, where they can move long distances to enter creeks, rivers and lakes and become part of the food chain, being transferred from organism to organism. There is currently no consistent evidence that exposure to PFOS and PFOA causes adverse human health effects. However, based on the evidence from animal studies potential adverse health effects cannot be excluded and studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals. Studies in laboratory animals suggest that PFOS and PFOA may promote some cancers in those animals, but it is not clear if these results have any implications for human health. A non-exhaustive list of human and animal health effects is presented below (from ITRC): 

Human (Possible Links) o Liver effects (serum enzymes/bilirubin, cholesterol) o Immunological effects (decreased vaccination response, asthma) o Developmental effects (birth weight) Endocrine effects (thyroid disease) o Reproductive effects (decreased fertility) o Cardiovascular effects (pregnancy induced hypertension) o Cancer (testicular, kidney)



Animal o Liver effects o Immunological effects

o Developmental effects o Endocrine effects (thyroid) o Reproductive effects o Haematological (blood) effects o Neurobehavioral effects o Tumours (liver, testicular, pancreatic)

3.1.2

Asbestos

Asbestos is the generic term applied to the naturally occurring hydrated mineral silicate fibres belonging to the serpentine and amphibole groups of rock-forming minerals. Asbestos is ubiquitous in the environment, with fibre release from natural sources and extensive industrial and commercial use of asbestos in the past. Asbestos and materials containing asbestos were widely produced in Australia between the 1940s and 1980s. The naturally occurring mineral has been mined then broken down from mineral clumps into groups of loose fibres for use in commercial applications. Asbestos only poses a risk to human health when elevated levels of asbestos fibres are breathed in. The likelihood of exposure occurring depends upon the potential for the asbestos material to release fibres, whether the asbestos material is contained or covered, and any operational control measures or personal protective equipment which have been applied to limit the generation and/or inhalation of airborne fibres. Non-friable asbestos, previously referred to as ‘bonded asbestos’, in sound condition represents a low human health risk. However, friable asbestos materials or damaged, crumbling bonded asbestos, have the potential to generate, or be associated with, free asbestos fibres and therefore must be carefully managed to minimise the release of asbestos fibres into the air. All types of asbestos fibres can cause health effects through inhalation. Some of the fibres will be deposited in air passages and on cells that make up the lungs. Most fibres are removed from the lungs by being carried away by macrophages or coughed up in a layer of mucus to the throat, where they are swallowed. Nearly all fibres that are swallowed are passed along the intestines within a few days and are excreted in the faeces. A small number of fibres may penetrate into cells that line the stomach or intestines and a few penetrate into the blood stream and are either trapped in other tissues or removed in the urine.

CES Document Reference: CES170608-GPR-DZ

CONSULTING EARTH SCIENTISTS

The health effects commonly associated with inhalation exposure to asbestos are asbestosis; lung cancer and a rare cancer called mesothelioma that affects the pleura and peritoneum membranes lining the chest and abdominal cavities, respectively. Benign pleural abnormalities can also result from asbestos exposure. The identification of other health effects is less convincing. The International Agency for Research on Cancer (IARC, 1987) and World Health Organization (WHO, 1986) concluded that the information for the development of other health effects, such as gastrointestinal cancer from inhalation or ingestion of fibres, is inconsistent and inconclusive. Asbestos has been shown to cause laryngeal cancer but to a much lesser degree than it causes lung cancer (Doll and Peto, 1985). Asbestos-related diseases evident today are largely a result of past high occupational exposures to persons employed in the asbestos mining and production industries or in the building trade. Current regulations are designed to provide greater control of exposure in occupational settings. GEOLOGY Reference to the Central Coast Area Coastal Quaternary Geology Map 1:100,000 Geological Map (Troedson A.L. 2016. Central Coast Area 1:100 000 and 1:25 000, Coastal Quaternary Geology Map Series. Geological Survey of New South Wales, Maitland) indicates that the site is underlain by early Triassic unit Munmorah Conglomerate as part of Narrabeen Group comprising sandstone, minor siltstone and white claystone. Investigations in the area of the GPM Landholding identified that the soils underlying the proposed storage area comprise Sandy CLAY, orange/brown, medium plasticity, dry, soft to firm; sand is fine to medium. HYDROGEOLOGY The storage area is likely to be underlain by a shallow phreatic and unconfined aquifer. Based on investigations completed in other areas of the GPM Landholding permeability ranges from 1.1 x 10-6 m/s to 4.7 x 10-9 m/s are typical of the residual soil and rock underlying the site. Based on interpolated groundwater contours the inferred groundwater flow direction is generally to the north with some localised variations. HYDROLOGY Surface run off from the area of the GPM Landholding is captured by the “Perimeter Chanel” a concrete lined drain designed to capture site stormwater. This portion of the perimeter channel has is divided, with flows on the internal portion of the divide discharged directly from the GPM CES Document Reference: CES170608-GPR-DZ

Landholding to the offsite receiving water body (Lake Munmorah) via the Inlet Canal Diversion Drain. The outer portion of the Perimeter Channel discharges to the Eastern Settling Basin and forms part of the GPM Landholding dirty water management system. Surface water runoff from the proposed storage area is likely to enter the internal portion of the Perimeter Channel.

STORAGE AREA SPECIFICATION

The following procedure should be implemented for the preparation the Storage Area and handling of contaminated materials. The proposed Storage Area location is presented on Figure 3. The area required to be prepared will be determined based on the final volume of soils to be managed and the available space. TEMPORARY BUNDS Temporary bunds should be constructed around the outer perimeter of the storage area to provide containment against leachate from the contaminated materials:    

The bunds should be constructed using low permeability compacted clay with a bund height of 1 m. The bund wall slope angle should be limited to 33 degrees. The temporary bunds should be constructed to provide a minimum of 1 m between the toe of any stockpiled contaminate material and the interior toe of the temporary bund. A geomembrane should be placed over the bund crest, bund wall and bund floor. The membrane should be extended across the storage area and placed above the prepared & compacted subgrade (Section 4.2).

A bund cross-section detail is provided in Figure 4. SURFACE PREPARATION It is recommended that the following is adopted for surface preparation of designated stockpile area: 

All uncontrolled fill, deleterious materials, topsoil, loose, soft soils or soils containing significant organic matter should be stripped and removed to expose a clay subgrade (assumed based on site experience and geological mapping). If a clay subgrade is not

CES Document Reference: CES170608-GPR-DZ

Page 14 of 21

CONSULTING EARTH SCIENTISTS

encountered, further Geotechnical advice should be sought, and the implementation of a HDPE liner or similar may be required. 

The exposed subgrade should then be scarified/ripped and moisture conditioned to within ±2% of Standard optimum moisture condition and then compacted to achieve a dry density ratio of not less than 98% Standard in accordance with AS1289 5.1.1 or 5.7.1, 5.4.1 and 5.8.1.;



It is recommended that subgrade preparation and compaction be performed by suitably experienced personnel and the level of compaction be checked by field density testing. Guidance for the frequency of field density testing is presented in AS3798 (2007) ‘Guidelines on Earthworks for Commercial and Residential Developments’. Subgrade compaction should be confirmed through the completion of field density tests at a rate of one test per 500 m2or 3 tests per full day of production i.e. Lot (whichever is greater).



Following compaction testing the storage area should be subject to a proof roll test under supervision of an experience geotechnical practitioner using a fully loaded dump truck to identify soft or compressible zones.



Any soft areas identified during preparation or proof roll test should be removed and replaced with suitable engineered clay fill. Where extensive soft or weak areas are encountered, it is recommended that further geotechnical advice should be sought.

MATERIALS HANDLING AND STOCKPILING Contaminated materials excavated from the site in accordance with the RAP and transported to the designated area as follows:  The storage area should be surveyed prior to placement of material.



Works should be completed in a manner which minimises the generation of dust;



Where asbestos impacted materials are excavated, transported and stockpiled, the works should be completed by a licenced asbestos removal contractor in accordance with an asbestos control plan. Asbestos fibre air monitoring should be undertaken in the excavation area and the stockpiling area.



During excavation and transport the materials should be kept in moist condition through the application of low-pressure water spray or misters. Soils should not be sufficiently moist to generate leachate and/or run off.



Material excavation and transport should be sequenced to minimise double handling or temporary placement of soils on previously uncontaminated areas of the site surface.



The materials should then be stockpiled within the Storage Area.

CES Document Reference: CES170608-GPR-DZ

Page 15 of 21

CONSULTING EARTH SCIENTISTS



Materials should be segregated and stockpiled in discrete areas of the stockpile area, with soils of similar type, contamination, and source.



Adequate space should be provided at the site for safe access, loading / unloading and inspection.



The recommended maximum stockpile height is 2m, however stockpiles up to 4m are considered acceptable, with a maximum slope angle of 45 degrees (assuming the material’s natural angle of repose).



Stockpile surfaces should be smoothed using an excavator bucket or back blading with a dozer.



The stockpiles should be covered with anchored low permeability covers (e.g., reinforced polyethylene or equivalent product). The covers should be anchored with weights placed on the top and along the base perimeter of the stockpiles, or other suitable system to ensure that the liners are maintained in place and in serviceable condition.



Erosion protection at the toe of the outer perimeter of stockpiles is to be implemented via the construction of a silt trap barrier. The silt fencing may be constructed at a height of 0.5m and anchored at 1.5m intervals. Life expectancy of silt fencing varies up to 6 months and should be monitored and replaced as required for the duration of on-site storage.

LEACHATE MANAGEMENT Stormwater and leachate collected within the storage area should be diverted and conveyed in between the bunds and stockpiles and subsequently towards the designated collection sumps, where one sump is proposed on each side of the storage area (see Figure 5). To achieve this the storage area should be graded at between 1 and 2 %.to drain to defined collection points (sumps). The leachate sumps should be regularly inspected and pumped out, particularly prior to and during periods of wet weather. Leachate pumped from the sumps should be discharged to temporary storage tanks to be maintained within a bunded area, prepared in a similar method to the Storage Area (refer to sections 4.1 and 4.2). Storage tanks should be regularly inspected to prevent overtopping and to ensure that sufficient capacity remains to manage leachate generated from the Storage Area. If required to maintain leachate storage capacity, additional capacity should be provided. Leachate should be tested regularly to determine PFAS concentrations and determine management options. CES Document Reference: CES170608-GPR-DZ

Page 16 of 21

CONSULTING EARTH SCIENTISTS

Leachate management options include:  

Offsite disposal at a suitably licenced waste facility; Onsite treatment and discharge (subject to regulatory approval). MODIFICATION OF THE PERIMITER CHANNEL

In the event that the proposed Storage Area bunds fail or are overtopped during periods of wet weather stormwater from the storage area will have the potential to be directly discharged from the site to the receiving water body (Inlet Canal Diversion Drain and Lake Munmorah) via the internal Perimeter Channel drain. As a precaution, it is recommended that the Perimeter Channel be locally modified to direct stormwater from the Storage Area to the GPM Landholding dirty water system by ensuring any water discharged from the Storage Area discharges to the outer portion of the Perimeter Channel. In addition to this precaution to minimise the risk associated with stormwater discharge from the Storage Area regular inspection of the bunding and leachate sump should be undertaken, and regular pump out of leachate (refer to Section 4.5) should be undertaken. DECOMISSIONING AND VALIDATION The following procedure should be adopted to decommission the storage area: Once a permanent solution to treat/manage the contaminated material has been identified the stored materials should be removed from the storage area. Material handling requirements presented in Section 4.3 should be adopted during removal. Following removal, a minimum of 100 mm of the surface of the storage area within stockpile footprints should also be excavated and treated in accordance with stored material as PFAS and asbestos impacted. Validation sampling should be undertaken to demonstrate that the whole footprint of the storage area has not been contaminated. Sampling should be completed in accordance with the density requirements presented in the NSW EPA (2022) Sampling Design Guidelines Part 1 – Application, or other appropriate guidelines which may be in place at the time. Validation samples should be analysed for PFAS and asbestos.

CES Document Reference: CES170608-GPR-DZ

Page 17 of 21

CONSULTING EARTH SCIENTISTS

Once validation sampling has confirmed that the area does not present a risk to human health or the environment that area bunding and leachate collection system can be removed. Prior to validation assessment the requirements of the EMP with respect to maintenance and management should be followed, with particular attention paid to the management of leachate/stormwater.

Appendix E QAQC Data Acceptance Criteria

CES Document Reference: CES170608-GPM-DS

Table I: QC Sample Data Acceptance Criteria QC Sample Type Blind Replicates and Split Samples

Method of Assessment

Acceptable Range

Field QC The assessment of split replicate is undertaken by calculating the Relative Percent The acceptable range depends upon the levels detected: Difference (RPD) of the replicate concentration compared with the original sample  0 – 100% RPD (When the average concentration is < concentration. The RPD is defined as: 4 times the LOR/EQL)  0 – 75% RPD (When the average concentration is 4 to 10 times the LOR/EQL)  0 – 50% RPD (When the average concentration is > | X1 – X2 | 10 times the LOR/EQL) RPD = 100 x Average Where: X1 and X2 are the concentration of the original and replicate samples.

Blanks (Rinsate and Trip Blanks) Laboratory-prepared Trip Spike

Laboratory Duplicates

Each blank is analysed as per the original samples. The trip spike is analysed after returning from the field and the % recovery of the known spike is calculated. Laboratory QC Assessment as per Blind Replicates and Split Samples.

Analytical Result < LOR/EQL 70% - 130%

Matrix Spikes

The acceptable range depends upon the levels detected:  0 – 100% RPD (When the average concentration is < 4 times the LOR/EQL)  0 – 50% RPD (When the average concentration is 4 to 10 times the LOR/EQL)  0 – 30% RPD (When the average concentration is > 10 times the LOR/EQL) Assessment is undertaken by determining the percent recovery of the known spike or 70% - 130% (General Analytes) addition to the sample. C-A 50% - 130% (Phenols)

Laboratory Control Samples

% Recovery =

Surrogates

100 x

B Where: A = Concentration of analyte determined in the original sample; B = Added Concentration; C = Calculated Concentration. Method Blanks

Each blank is analysed as per the original samples.

60% - 130% (OP Pesticides) If the result is outside the above ranges, the result must be < 3x Standard Deviation of the Historical Mean (calculated over past 12 months) Analytical Result < LOR/EQL

Note: EQL = Laboratory Estimated Quantitation Limit (EQL) or the minimum detection limit for a particular analyte. LOR = Limit of Reporting or the minimum detectable limit for a particular analyte.

Appendix F UXF Procedure

CES Document Reference: CES170608-GPM-DS

MANAGEMENT OF UNEXPECTED FINDS In the event that unexpected buried features or contamination sources are encountered during the course of site works, the following contingency measures for the management of potential types of contamination should be taken as nominal responses in the absence of a specific plan. Contamination type or feature

Nominal response

Significant unexpected features such as fibrous asbestos or potentially hazardous finds

Work in the area should cease and an appropriately qualified Environmental Consultant should be contacted for assessment of the area.

Coal ash deposits and coal ash impacted materials

Work in the area should cease and an appropriately qualified Environmental Consultant should be contacted for assessment of the area.

The sequence of work undertaken should follow advice given at the time by the Environmental consultant but is likely to require isolation or secure stockpiling of the material separately as potentially contaminated for later assessment, or it may require to remain in place with work in that area suspended pending more detailed assessment.

The sequence of work undertaken should follow advice given at the time by the Environmental consultant but is likely to require the excavation and stockpiling of the ash deposits for assessment. Ash deposits may be suitable for relocation to the Munmorah Ash Dam, provided the material is not impacted by cocontaminants such as PFAS.

Underground structures, buried drums or underground tanks.

Work in the area should cease and an appropriately qualified Environmental Consultant should be contacted for assessment of the area. The sequence of work undertaken should follow advice given at the time by the Environmental Consultant. Works - with oversight by the Environmental Consultant - is likely to comprise careful removal of the drum/s or tank/s from the excavation, photographing the condition of the drum or tank, collection of validation soil samples from the excavation walls and base, and isolation of the drum or tank in a secure bunded area for later assessment. If a drum or tank has leaked, any associated contaminated soil should be removed and placed with the drum/s or tank. Waste classification analysis will be required of the impacted soil prior to offsite removal. Work in the area should resume only once the Environmental Consultant has

deemed it appropriate.

Major exposures of odorous, discoloured or stained soil

Work in the area should cease and an appropriately qualified Environmental Consultant should be contacted for assessment of the area. The sequence of work undertaken should follow advice given at the time by the Environmental consultant but is likely to require separate and secure stockpiling of the material as potentially contaminated for assessment.

Depending upon the contamination which may be discovered, it may be necessary to prepare and implement specific work method statements and procedures to address the assessment, handling and disposal of unexpected findings during the bulk earthworks. Assessments of suspect materials and preparation of any such plans or procedures should only be carried out by a qualified environmental scientist or engineer. At any stage of the earthworks project when unexpected finds are encountered, the initial notification must be made immediately to the site supervisor who will then contact the appropriate environmental consultant and determine what interim measures should be applied. If any material requires specific segregation and removal due to potential or actual contamination, then after removal the surrounding material may require to be sampled and tested for the contaminant of concern before excavation continues. This to be as directed by the environmental consultant.
