1.1 INTRODUCTION

The preparation of this Quarry Operation Management Plan (“QOMP”) has been co-ordinated for SRC Operations Pty Ltd by RW Corkery & Co. Pty Limited (RWC) to document the manner in which the approved extraction operations within the Patons Lane Resource Recovery Centre (“the Project”) will be undertaken throughout its operational life. Emphasis is placed in the QOMP upon the planned extraction operations and the management of the stockpiles of material extracted from the cells that will ultimately be backfilled with waste.

This document has been prepared focusing upon the extraction activities in the first cell (Cell 1) and the stockpiling of materials extracted from this cell. This approach has been adopted in accordance with Schedule 3, Condition 32 of Project Approval MP09_0074 (“the Project Approval”) which provides for the staged submission of Management Plans for the Project with the approval of the Secretary of the Department of Planning and Environment (DP&E). Correspondence with the Secretary of DP&E confirming approval for the submission of staged plans for the QOMP is attached in Appendix 1.

Considerable care has been taken to ensure that the quarry operations and the construction of Cell 1 remains entirely consistent with the Further Modified Preferred Project Report (FMPPR) and the other plans specified in the project approval. The cell design was developed with reference to all relevant plans in the project approval. A review of the cell design and compliance with the project approval was conducted during a teleconference with representatives of the client, Douglas Partners, Lead Auditor Trevor Brown and independent subject matter expert Ian Swane (Practice Leader Jacobs Practice Leader – Contaminated Land Management; Principal Engineer, Site Auditor) on 14 May 2015.

Accordingly, the volumes of material to be extracted remain the same as set out in the project approval. Extraction operations for Stage 1 are designed around Cell 1 and involve the removal of an estimated 769 000 tonnes of material. Details of the materials and volumes to be extracted are set out in Section 5.3. These activities are entirely consistent with the project approval. The FMPPR shows a total of 733 815 tonnes of material to be extracted from Cell 1 (Source Table 2.3). The small increase of 35 185 tonnes is due to the excavation of an access ramp on the northern boundary which is constructed in the area of Cell 2 (estimated at 37 600 tonnes as set out in Table 5).

Figure 1 displays the location of the Patons Lane RRC, within a 60ha area of land located west of Luddenham Road, Orchard Hills, referred to throughout this document as “the Site”.

1.2 OBJECTIVES

The key objectives of the QOMP are to:

i) satisfy the requirements of Schedule 5 Condition 4 of Project Approval MP09_0074.

ii) provide an overview of the overall extraction plan for the entire site for the life of Patons Lane RRC;

provide a level of detail for the extraction operations in Cell 1;

2.1 OVERVIEW

The Patons Lane Resource Recovery Centre (‘the Project’), located in Orchard Hills, NSW is a resource management facility located within Lot 40, DP 738126, i.e. the former Erskine Park Quarry owned by SRC Operations Pty Ltd (‘the Principal’). Project Approval MP09_0074 was granted by the NSW Land and Environment Court for the establishment and operation of the resource recovery centre in August 2012 and approved for the landfilling of commercial and industrial (C&I) and construction and demolition (C&D) waste types (general solid (non-putrescible) waste).

The objectives of the Patons Lane Resource Recovery Centre (RRC) are to:

• provide a facility to assist the NSW Government to meet the recycling targets forC&I and C&D waste;

• recover a high proportion of clay/shale resources for the brick and constructionindustry;

• receive and emplace wastes and residuals from the on-site recycling; and

• progressively rehabilitate a disused quarry to re-instate the agriculturallyproductive land consistent with the surrounding lands.

2.2 MANAGEMENT PLAN FRAMEWORK

Approval was obtained from the Department of Planning and Environment (DP&E) pursuant to Condition 32 of Schedule 3 of the Project Approval to submit all but two plans (the Site Establishment Noise Management Plan and the Construction Traffic Management Plan) in stages. Stage 1 is defined as being works and activities up to the completion of the extraction of Cell 1, and is estimated to take five to seven years. Stage 1 plans, apart from those outlined above, will need to be updated prior to undertaking subsequent Stages 2 and 3.

In accordance with the requirements of the Project Approval, this plan and other plans of management relevant to Site Establishment for the Project were approved by the DP&E and verified via a Pre-Site Establishment Audit process, prior to the commencement of the Site Establishment works and activities (i.e. construction works). Prior to the commencement of operations (i.e. the receipt of any waste materials) additional plans must be prepared and approved by DP&E (in accordance with the Project Approval) and verified via a separate Pre-Operational Compliance Audit.

All site establishment and operations management plans are designed to work in conjunction with the Landfill Environmental Management Plan (LEMP) which provides the overarching environmental management framework for the Project. An outline of the management plan framework is shown in Figure 2.

The management plan approval process is outlined in Figure 3.

2.3.2 Site Establishment and Construction of the RRA

The details of these works and activities which have been included in the assessment undertaken to develop the Construction Traffic Management Plan and the Site Establishment Noise Management Plan (SENMP) are set out below.

These construction activities are expected to take 18 months to complete and will be carried out within the following parameters:

• Hours of Construction:

1. Monday to Friday 7am to 6pm

2. Saturday 8am to 1pm

3. Sunday, no work

• Personnel:

1. Construction: 10 to 15 people.

Site Establishment

The site establishment works and activities are as follows:

• Construction/shaping of the northern face and much of the eastern face to theirfinal rehabilitated landform and landscaping of those faces. Construction of thenorthern face will be achieved through the following:

1. Reshaping the existing north eastern and north western bund walls, byreducing their height in some areas, raising their height in other areas tocreate an even northern face with a maximum elevation of 53 m AHD, and amore gentle northerly slope than currently exists. The new northern face andacoustic mound will provide acoustic protection for earthmoving andlandfilling equipment/vehicles operating within Cells 1 and 2. The acousticmound will be removed at the conclusion of capping in Cell 2 when it is nolonger needed for acoustic protection.

2. Areas to the north of the acoustic mound will be regraded to their finalrehabilitated landform with slopes of approximately 5%. Final landscapingof these areas will occur during site establishment.

• Partial rehabilitation of the existing southern and southwestern bund walls throughthe reduction in the elevation to an approximate elevation of between 57 m AHDand 58 m AHD such that they will not be visible from any residence within TheVines Estate. Once re-shaped, the surface and adjoining batter slopes will berevegetated.

• Upgrading and sealing of Patons Lane and upgrading the entrance to the site(from Patons Lane) together with the installation of three weighbridges andupgrade of associated office building.


10

• Site preparatory works within the recycling and re-processing area to create the required landform and create a suitable pad for the materials recycling facility warehouse and mobile recycling equipment.

• Construction and commissioning of the on-site wheel wash facility.

• Upgrading and sealing the internal road network beyond the proposed wheel wash facility to the exit point from the recycling and re-processing area.

• Building and construction works and infrastructure works as shown in Figure 4.

These works and activities will be undertaken generally in the order set out below (and referenced on Figure 4) noting that the scheduling of specific works will be dependent on factors such as weather, commercial factors including contractor availability, specific logistical requirements and many other issues and will vary accordingly. In addition, many of the works and activities will need to be undertaken simultaneously. The works and activities associated with site establishment are as follows:

1. Construct surface water controls (integrate dams as required)

2. Excavation of stockpiled clay/shale and construct northern face (external and Internal slopes)

3. Regrading/shaping areas north of the northern face

4. Dewatering of quarry void

5. Landscaping northern face

These items are largely buildings and structures that will be subject to Construction Certificates, BCA regulations and Occupation Certificates certified by an approved certifying authority.

The infrastructure permitted to be constructed as part of the RRA will be undertaken generally in the order set out below (and referenced on Figure 5) noting that the scheduling of specific works will be dependent on factors such as weather, commercial factors including contractor availability, specific logistical requirements and other issues and will vary accordingly. In addition, many of the following works and activities will need to be undertaken simultaneously:

1. Drainage works 2. C&D / C&I Recycling Building 3. Product Bays 4. Delivery Area 5. Road network 6. Crushing and Screening Area 7. Recycling Facility Warehouse 8. Amenities building 9. Car Park.

2.3.3 Operation

The specific works and activities associated with Stage 1 operations are the: • emplacement of wastes into Cell 1A; • construction of Cell 1B and 1C including the selective extractive operations to

extract the clay/shale resource and related stockpiling activities; and • receipt and processing of wastes in the RRA with residuals being compacted,

baled, and emplaced in Cell 1A and 1B.

Figure 6 shows the general arrangement of Cell 1.

Compacted and baled residual waste will be transported from the RRA to the landfill cell via a dedicated on-site heavy vehicle fitted with a walking floor trailer.

Mobile plant and equipment to be used for the placement of waste into the cells include an excavator with a detachable grab attachment for handling the baled waste, and a bucket attachment for movement of daily cover. A compactor will also be used to provide further compaction of residual waste.

Bulldozers, dump trucks and excavators will be used for the excavation of Cells 1B and 1C.

3.1 CONSULTATION REQUIRED BY THE APPROVAL

The project approval requires that the QOMP must

“b) be prepared in consultation with the EPA and Council”

Accordingly, thorough consultation was undertaken with these agencies as well as the DP&E during the preparation of this document as required by the project approval. Chronological details of the consultation and all relevant correspondence in contained in Appendix 1.

Consultation with government agencies undertaken during the preparation of this document is summarised as follows:

1. Discussions with, and correspondence to, DP&E seeking approval to prepare a Quarry Operation Management Plan (QOMP) in stages with the first stage focusing on the extraction and stockpiling activities for Cell 1. This correspondence was sent to the DP&E in accordance with Schedule 3, Condition 32 on 27 November 2015. The correspondence to the DP&E also sought to obtain support to modify the nominated (and impractical) method of stockpile construction and provided in Schedule 5, Condition 4(i). A copy of the DP&E’s written response dated 18 May 2016 is presented in Appendix 1.

2. Discussions with, and correspondence to the Environment Protection Authority (EPA) and Penrith City Council seeking their input to the issues to be addressed in this document. This correspondence was sent to both agencies in response to the requirement of Schedule 5, Condition 4(b). The correspondence to the EPA also sought to approve a variation to the batter slopes of stockpiles of materials extracted and stockpiled on site (i.e. in response to the requirement in Schedule 5, Condition 4k).

Discussions were held with the EPA on 7 March 2016 and correspondence was provided by the EPA on 11 April 2016. The EPA approved the draft QOMP on 27 May 2016 (see Appendix 1).

A meeting was held with Penrith City Council on 25 February 2016 and correspondence was provided by Council on 22 April 2016. PCC indicated on 11 April 2016 that the “QOMP appears to satisfy the requirements of the relevant condition of consent” and further advised on 22 April 2016 that they had no objections to the staged approach (see Appendix 1).

3.2 COMMUNITY CONSULTATION

There is no formal requirement within the Project Approval for specific consultation with the community regarding the QOMP. However, general community consultation for the Project has been undertaken by SRC with respect to the overall Project. SRC has undertaken a letter box drop with follow-up one-to-one discussions held with interested neighbours. A component of these discussions has related to SRC's overall program for the submission of a range of management plans, including this document. It is noted that all management plans including the QOMP are required to be available on the Patons Lane RRC website (patonslanerrc.com.au).

Additionally, the community will be kept informed of the development of various plans via the Community Liaison Committee (CLC).

4. AP P R O V E D S I T E L AY O U T AN D AC T I V I T I ES 4.1 APPROVED SITE LAYOUT

Figure 7 displays the site layout approved by the NSW Land and Environment Court. This figure is shown as Schedule 8 of the Project Approval being Appeal No. 10928 of 2010 and is identified as GHD DRG No. 21-10649-Y00. The layout comprises of the following key components.

1. An extraction area, part of which has previously been extracted covering a total area of 24.5ha. The extraction area comprises three cells, namely Cells 1, 2 and 3 each of which has been subdivided into three sub-cells namely: Cell 1A, 1B and 1C; Cell 2A, 2B and 2C; and Cell 3A, 3B and 3C. The three extraction cells are proposed as the repositories for approved wastes.

2. A waste recycling and re-processing facility located within the southwestern corner of the Site in an area surrounded by an existing perimeter bund wall and a new internal bund wall. The footprint of the waste recycling and re-processing facility is approximately 5.6ha.

3. On-site infrastructure comprising site offices and amenities, weighbridges, workshop and internal roads.

4. On-site water and leachate management structures. Some of the dams within the Site are already constructed whilst other dams are proposed to be constructed. In some cases, the locations of the dams will be temporary as they will need to be relocated throughout the life of Patons Lane RRC.

5. Parts of the existing northern perimeter bund walls will be upgraded to provide the level of visual and acoustic protection for Patons Lane RRC to operate with an acceptable impact upon the amenity of surrounding landholders and occupiers.

4.2 APPROVED ACTIVITIES 4.2.1 Clay/Shale Extraction and Stockpiling

The extraction of clay/shale within the total approved extraction area will serve three purposes, namely:

i) the provision of approximately 3.15 million tonnes of clay/shale raw materials for brick manufacture;

ii) the provision of approximately 2.05 million tonnes of clay/shale for uses within the landfill component of Patons Lane RRC, i.e. for lining the floor of the waste cells, daily or intermediate cover and capping materials; and

creation of a void (within its related air space) that will provide sufficient volume for the emplacement of 4.3 million tonnes of waste.

19

For the purposes of the development application for Patons Lane RRC, Cell 1 was subdivided into three areas, referred to as Cells 1A, 1B and 1C (see configuration in Figure 7). For the purposes of this document, the boundaries of Cells 1A, 1B and 1C have been slightly modified to accommodate the results of the mining engineering design and design of the waste cells within Cell 1. The modified cell boundaries are relied upon throughout this QOMP.

The extraction of clay/shale materials to create the void for waste emplacement will require the various materials to be stockpiled until they are transported off site for brick manufacture or used on site for the uses outlined in (ii) above.

4.2.2 Recycling and Re-processing Operations

The recycling and re-processing operations will be undertaken within a dedicated area covering approximately 5.6ha (see Figure 7). The waste recycling and re-processing area will be surrounded by an acoustic earth mound which will restrict its visibility and noise propagation.

The recycling and reprocessing area will incorporate both commercial and industrial (C&I) recycling as well as the construction and demolition (C&D) re-processing. A series of bays will be constructed on the eastern side of the area for the storage of products produced in both of the above facilities.

Residual wastes from both the C&I and C&D re-processing operations will be placed in the on-site landfill.

4.2.3 Landfilling

The landfill cells created within Patons Lane RRC will be developed as a state-of-the-art landfill for the emplacement of the residual wastes generated by the on-site re-processing operations and other wastes delivered from external sources which cannot be re-processed or recycled.

The landfill will be developed as three cells, each with their own leachate collection system. The cells will vary in elevation from approximately 17m AHD to 30m AHD (Cell 1), 28m AHD to 31m AHD (Cell 2) and 28m AHD to 31m AHD (Cell 3). Each landfill cell will be developed progressively following the extraction of the clay/shale present to the depth nominated in Figure 9. Each Cell will be lined with 1m of compacted clay extracted on site and 0.3m of drainage material. Table 2 lists the quantities of clay required for the liner within each Cell.


20

Table 2

Clay Quantities Required for Liner in Cell 11

All wastes placed within the landfill cells will be covered on a daily basis with at least 150mm of cover material, principally general purpose shale recovered on site. Intermediate cover will also be applied to those sections of the landfill not required for operational purposes for in excess of three months. For the purposes of planning, the quantity of daily and intermediate cover, will equate to approximately 5% of the waste volume within each section of the landfill. Table 3 lists the quantities of cover material required for the wastes placed within Cells 1A, 1B and 1C.

Table 3

Daily and Intermediate Cover Requirements1

Once the final landform level has been reached within the active landfill area, the final landform will be capped with a combination of materials comprising subsoil (0.75m of on-site clay), a sealing layer (0.6m of on-site clay) and seal-bearing layer (0.3m of on-site general purpose shale). Table 4 lists the quantity of clay and general purpose shale required for the capping of the final landform created during the extraction of Cell 1 and the related landfilling activities.

4.2.4 Off-site Clay/Shale Transportation

Schedule 3 Condition 23 limits the transportation of clay/shale off site for brick manufacture to 160 000tpa throughout the operational years of Patons Lane RRC. This quantity of clay/shale will be removed at an average of approximately 22 laden trucks per day. The approved maximum daily number of heavy vehicle movements is 250 per day.

4.3 EXTRACTION AREA AND STOCKPILING LAYOUT

For the purposes of this QOMP, Figure 8 presents the key extraction areas, i.e. within Cells 1, 2 and 3 and the three principal stockpiling areas, namely the northern, central and southern (contingency) stockpile areas. Other project components have been removed from this figure to enable a focus on the extraction and stockpiling operations.

Within the extraction area, two internal haul roads will be developed, both of which will be unsealed.

i) An internal road for waste trucks delivering waste to be active waste cell. Figure 8 shows this road will be aligned around the eastern side of Cell 3 and the eastern and north sides of Cell 2. This road will retreat as the waste cells are filled.

ii) An internal road for earthmoving equipment to travel to and from Cell 1 and for the removal of clay/shale from Cell 1 by scrapers and off-road haul trucks for placement within the stockpile areas. The road is strategically positioned between the northern and central stockpile areas.

5.1 GEOLOGICAL SETTING

The Site is underlain by a sequence of rocks within a geological unit referred to as the “Bringelly Shale”, a formation the Wianamatta Group that crops out over most of the Sydney’s western suburbs.

The Wianamatta Group is the main source of raw materials for the production of structural bricks in the Sydney region (Herbert, 1979). The Bringelly Shale generally comprises a sequence of consolidated sediments including claystone, siltstone, laminite, sandstone, tuff and coal. This unit is preferred for brick production due to its favourable plasticity characteristics and ability to produce a range of different fired colours including light-fired colours recovered from selectively extractable units.

In the vicinity of the Site, the Bringelly Shale dips gently to the southwest at approximately 5o and has been interpreted to be approximately 50m to 55m thick. The sediments show strong lateral facies variation, especially in the coarser grained sandstone beds, resulting in difficult lithological correlation of between drill holes. Minor faulting is evident within the existing extraction area but is not thought to significantly constrain the geological interpretation between drill holes.

Weathering of the sequence of rocks beneath the Site is generally intense in the top 3m to 4m from the surface. Weathering intensity decreases rapidly with depth below the zone of intense weathering with relatively fresh rock generally encountered within 4m to 8m below the natural surface.

5.2 RESOURCE TYPES

The resource types within the Site are categorised firstly upon the material type and secondly upon fired colour. For the purposes of this document, the key material types are:

i) clay;

ii) weathered shale;

iii) shale

iv) shale and laminite; and

v) sandstone.

The term “shale” embraces both claystone and siltstone rock types.

The materials to be extracted exhibit a wide range of fired colours generally reflecting the proportion of iron oxides in the clay and weathered shale and iron carbonate (siderite) in the unweathered shale and laminite.

Given the range of material types and fired colours, a total of seven groups of materials have been defined within the Site. For the purposes of this document, the materials on site and their intended uses are set out in Table 5. The nominated material types in Table 5 are generally consistent with terms used by the brick industry.

5.3 RESOURCE QUANTITIES

The resources to be extracted from Cell 1 have been quantified by RPM Global based upon the geological model compiled from data assembled in RWC (2004) and the consideration within four distinct areas within the extraction area, namely:

1. Northern ramp; 2. Cells 1A and 1B; 3. Cell 1C (upper level) and part of the southern ramp; and 4. Cell 1C (lower level) and part of the southern ramp.

The resources within Cells 1A and 1B are combined given the proposed extraction floor within that area of Cell 1 is similar to the existing extraction floor and the materials within that area will need to be extracted prior to the commencement of the liner construction in Cell 1A.

The resources within Cell 1C (upper level) and Cell 1C (lower level) have been reported separately given it is the clay materials and weathered shale within the upper level that will be required for use as the clay liner in Cell 1A.

Table 6 lists the estimated quantity of each type of material within each of the defined areas within Cell 1. It is noted that the quantities of resources were estimated through calculations of material volumes from the geological model and the conversion to tonnes assuming the following material specific gravities.

• 1m3 of clay = 1.8 tonnes/m3 • 1m3 of weathered shale = 2.0 tonnes/m3 • 1m3 of shale, siltstone, etc. = 2.2 tonnes/m3 • 1m3 of sandstone = 2.4 tonnes/m3

The quantities in Table 6 are strictly indicative as a range of variables influence the exact quantity of each material type extracted.

Table 6 also includes a quantity of fill materials that is currently located within a section of the existing perimeter bund wall whose footprint is located above the southwestern corner of Cell 1C.

Table 6 presents the resources within Cell 1 in terms of the following.

• Bank cubic metres (bcm), i.e. the in situ volume of materials calculated from the Cell 1 model.

• Loose cubic metres (lcm), i.e. the expanded volume of material calculated by increasing the bcm quantity by a conservative factor of 25%.

• Tonnes (t), i.e. the weight of the material calculated by multiplying the bcm by the nominated specific gravity.

Figure 8 displays the approved extraction area within the Site. Overall, the extraction area covers approximately 24.5ha of which approximately 5.4ha has already been disturbed by extraction activities. A small quantity of resources remains within the area previously extracted.

The extraction plan comprises three cells, namely, Cells 1, 2 and 3 with a total of nine sub-cells.

6.1 OVERALL EXTRACTION PLAN

Figure 9 displays the layout of the entire extraction area at the end of the extraction operations. The floor of the extraction area will be profiled to create the required basal topography for the waste cells. Elevations of the floor level within Cell 1A will vary from approximately 31m AHD to 17m AHD with the deepest area reflecting the existing extraction floor in that section of the cell. Elevations of the floor levels within Cells 1B and 1C will vary from approximately 28m AHD to 31m AHD. In the event cream-firing shale is exposed on the extraction floor, SRC will determine whether it is appropriate to remove the resource and replace it with lesser value clay/shale.

Figure 9 shows that Cells 1, 2 and 3 will be separated by a retained section of clay/shale (or compacted clay) up to 10m wide to assist in the long-term management of leachate within each cell by separating leachate capture into three distinct catchments and collection systems.

6.2 CELL 1 EXTRACTION PLAN

Figure 10 displays the layout of Cell 1 at the end of the extraction operations and Figure 11 displays the sequence of extraction through four distinct areas within Cell 1, i.e. those used for the definition of clay/shale resources (see Section 5.3).

1. Northern ramp

2. Cells 1A and 1B

3. Cell 1C (upper level) and part of the southern ramp

4. Cell 1C (lower level) and part of the southern ramp

Northern Ramp

The northern ramp will be excavated largely within the footprint of Cell 2 to provide for the long-term access for trucks delivering waste to the active waste placement area in Cell 1. The ramp will vary in grade from 1:10 (V:H) to 1:12 (V:H) and will extend from an elevation of approximately 44m AHD to approximately 31m AHD at the northeastern corner of Cell 1. Figure 11A displays the area and configuration of extraction to create the northern ramp.

The material extracted from within the northern ramp will be largely red clay and white/pink clay which will be transferred to the floor of Cell 1 and stockpiled within the floor of Cell 1B. The remainder of the material will be effectively blended and placed within the GP Shale stockpile area (see Section 8.2).

Cells 1A and 1B

Where practicable, the material within Cells 1A and 1B will be extracted in a manner that will remove the individual clay/shale and sandstone units. Figure 11B displays the area and configuration of extraction within Cells 1A and 1B. It is recognized that selective extraction of the individual units may be difficult, if not impossible, particularly in the area centered on the existing floor of Cell 1A.

It is noted that it may be preferable to extract sections of the floor in Cell 1B prior to the excavation of the northern ramp so that the clay from the ramp (and perhaps the relocated Dam 4) can be stockpiled in that area for use in lining Cell 1A.

All materials extracted from Cell 1A and 1B will be transported to the clay/shale stockpile areas via the northern ramp.

Cell 1C (Upper Level)

The upper level of Cell 1C (i.e. to approximately 40m AHD) will be extracted principally to provide the remainder of red clay required for the lining of Cells 1A, 1B and 1C. Figure 11C displays the internal layout for extraction within Cell 1C whereby an internal ramp will be constructed to provide access from the upper level of Cell 1C to the floor of Cell 1 to enable the clay to be stockpiled within Cells 1B and 1C. The proposed internal ramp will follow the general alignment of a former internal road within the former extraction area. Extraction will cease within the upper cell once all clay required is transported to the floor of Cell 1.

Cell 1C (Lower Level)

Following the delivery of all the required red clay to the floor of Cell 1, the remainder of the clay/shale within Cell 1C will be extracted and transported to the defined stockpile areas to the east of Cell 1. Figure 11D displays the proposed southern ramp that will be constructed progressively from Cell 1C to the internal road for earthmoving equipment between the northern and central stockpile areas. Extraction will continue in Cell 1C until all clay/shale is extracted to defined floor, as displayed in Figure 11D.

7.1 QUALITY CONTROL

An important activity in the extraction operations will be the daily quality control procedure to establish the fired colour of the material(s) to be extracted during the following day(s). This will underpin a protocol to ensure stockpiles of clay/shale materials for use by the brick industry are kept separate from material to be used for cell construction, daily waste covering and capping. Quality control within the extraction area will involve the following procedure.

The protocol is designed to maximise the volume of extracted materials quarantined for use by the brickmaking industry. Prior to the cessation of activities at the end of each day during each extraction campaign, the bulldozer will rip a series of lines across the active extraction floor which will bring to the surface a range of materials from approximately 0.6m to 1m below the extraction floor.

Representative samples of the ripped material will be sampled, numbered using a manganese dioxide solution and placed in a test kiln overnight at approximately 1020°C. The location of each numbered sample will be spray painted onto the extraction floor.

The fired samples will be examined the following morning and assessed for their fired colour and a record made for discussions/directions to the on-site extraction supervisor and equipment operations. The fired colour assessment will be based on an agreed colour board assembled from previously fired samples. Stockpiles of brick making materials will be delineated based on these predetermined colour characteristics. Extracted materials will be directed to the appropriate stockpile following this daily assessment.

7.2 EXTRACTION METHODS AND EQUIPMENT

Extraction of clay/shale materials within the three sub-cells will be undertaken typically on a campaign basis to ensure sufficient volume is available for the projected landfilling requirements. Extraction will typically involve the following.

i) Any recoverable topsoil and/or subsoil will be recovered using a scraper and either stockpiled for use in future rehabilitation or directly transferred to an area being rehabilitated.

ii) Where red clay is present, it will be recovered using a scraper and placed on the floor of the cell adjacent to Cell 1A.

iii) Any white/pink clay recovered and not required for cell lining will be transported to the active stockpile area for the later despatch for brick manufacture.

iv) The weathered shale, fresh or unweathered, laminite and sandstone units will be ripped (and possibly cross-ripped) with a bulldozer after which it will either be: – recovered by a scraper and placed in the active stockpile area; or – pushed into a stockpile on the extraction floor and loaded by excavator into an

on-site haul truck (for transfer to the active stockpile area) or a road registered truck for despatch off site.

It is noted that the proposed extraction area layout reflects the use of scrapers which invariably require a greater area for access and manoeuvring.


34

7.3 SEPARATION FROM LANDFILL OPERATIONS – Schedule 5 Condition 5(4)(e)

Figure 12 displays the extraction sequence in Cell 1 and the proposed locations of the internal intercell bund to be constructed to separate the area of waste placement (and leachate generation) and area of clay/shale extraction/stockpiling. Apart from separating leachate from sediment laden runoff, the intercell bund will provide a physical barrier between the ongoing extraction and waste placement operations. The intercell bunds are generally consistent with those displayed in Schedule 10 of Project Approval MP09_0074.

The intercell bunds shown on Figure 12 are displayed at their minimum width of 10m as the opportunity may arise to effectively increase the width and height of the barrier to effectively store red clay for its subsequent use in the construction of the cell liners within Cells 1B and 1C.

7.4 EXTRACTION SEQUENCE

Extraction will commence in Cell 1A and 1B and progress in accordance with the staged emplacement cells, namely 1A 1B 1C 2A 2B 3A 3B 3C.

7.5 EXTRACTION RATES

Extraction rates will be tailored in any one year to ensure:

i) sufficient void volume is available for landfilling purposes;

ii) the full quantity of brick manufacturing raw materials (160 000tpa) are extracted for despatch from site; and

iii) the required quantity of cover and capping materials are available.

Extraction rates within Cell 1 will reflect the requirement for:

• the on-site requirement for clay to line Cell 1;

• the expectation for the supply of 160 000 of materials annually for brick manufacture.

8.1 STRATEGY

The quantity of clay/shale that needs to be stockpiled throughout the life of the Patons Lane RRC will be dictated by the following factors.

i) The need to ensure sufficient clay/shale is extracted to provide the void space required for the progressive waste placement and backfilling operation.

ii) The quantity of materials used on site or transported off site for brick manufacture.

Based upon the planning for this document, it will be necessary at all times throughout the life of the facility to maintain a range of stockpiles on site. Emphasis will be placed upon separating the stockpiles of materials to be used on site from those to be transported off site.

This section presents the protocol to be adopted that will enable SRC to manage the location, construction and progressive removal of the materials stockpiled for on-site use or for despatch off site.

8.2 STOCKPILE LAYOUT

Figure 8 displays the three principal clay/shale stockpile areas, namely:

i) the Northern Stockpile Area;

ii) the Central Stockpile Area; and

iii) the Southern (Contingency) Stockpile Area.

Northern Stockpile Area

The northern stockpile area is located wholly within the footprint of Cell 2 covering an area of approximately 5.4ha. The land within this area slopes from the southeast to the northwest at a grade of approximately 1.5%. The northwestern corner of the northern stockpile area has been designated as the location of the relocated Dam 4 to collect runoff from the northern stockpile area and the unsealed internal road to be used by waste trucks travelling to and from the active waste emplacement area.

Central Stockpile Area

The central stockpile area is located wholly within the eastern side of the footprint of Cell 3 covering an area of approximately 4.0ha. The area slopes from the south (at 50m AHD) to the northwest (at 47m AHD) also at a grade of approximately 1.5%. Runoff from the central stockpile area will be directed to Dam 5 to the northwest of the area.


38

Southern (Contingency) Stockpile Area The southern (contingency) stockpile area is located within the southeastern corner of the Site and covers an area of approximately 2.6ha. The area slopes from the north to the south at a grade of approximately 2%. Runoff from the southern (contingency) stockpile area will be directed to the south towards Dam 6. The eastern side of this area is currently occupied by the southern section of the existing eastern bund wall. The materials within this bund wall will be progressively removed throughout the early years of the operation to make the full footprint of the stockpile area available for stockpiling clay/shale and sandstone extracted from Cells 1, 2 and 3. The eastern side of the existing eastern bund wall will be retained as displayed on Figure 7.

Schedule 4 Condition 24 restricts the upper surface of all stockpiles of materials extract on site to 54m AHD.

These limitations will result in the stockpile heights within each stockpile area being limited as follows.

– Northern Stockpile Area - 7m to 11m – Central Stockpile Area - 4m to 7m – Southern (Contingency) Stockpile Area - 6m to 10m

The designation of individual stockpile areas within the three stockpile areas will need to be dynamic to reflect the quality control results discussed in Section 7.1. As such, the area(s) for the stockpile(s) of each material type will need to be reviewed and adjusted throughout the life of Patons Lane RRC.

Tables 7, 8 and 9 list the indicative quantity of materials to be extracted from each of the four areas nominated in Figure 11. Distinction is made between the materials to be:

a) used either directly without long term stockpiling; b) stockpiled for use through the life of Cell 1; and c) stockpiled for use by the brick industry.

For planning purposes, the materials extracted during the construction of the northern ramp and Cell 1A and 1B are considered together.

Figure 13 displays the indicative layout of the stockpile areas for the materials extracted from within the northern ramp and Cells 1A and 1B. Not all stockpile areas would be used during this period of extraction. The type of material stockpiled with the stockpile areas is nominated on Figure 13. It is assumed that the quantity of clay required for lining Cell 1A will be recovered from the northern ramp and Cells 1A and 1B from the excavation of Dam 4.

Figure 13 displays an indicative arrangement of the stockpiles within the Site. Three stockpiles sizes are displayed, namely:

• 100m long x 50m wide (approximately 22 000lcm / 40 000t capacity);

• 80m long x 50m wide (approximately 18 000lcm / 30 000t capacity); or

• 100m long x 75m wide (approximately 32 000lcm / 52 000t capacity.

Each of the stockpile areas are numbered N – Northern / C – Central / S – Southern. Whilst the stockpile areas displayed on Figure 13 show the footprint of the stockpiles the area may not be constructed to the full height or cover the full area of the stockpile area. The full height of some of the stockpiles would be achieved during the extraction in Cell 1C (upper level).

Figures 14 and 15 display indicative layouts for the stockpiles containing the materials extracted from within Cell 1C (upper level) and Cell 1C (lower level). The types of material stockpiled within each stockpile area are nominated on both figures.

From an operational perspective, it is proposed to construct the stockpiles within the northern and central stockpile areas typically with a height of approximately 4m to 6m and each with a capacity of approximately 18 000lcm and 22 000lcm) other than stockpile area C1. Stockpiles of this capacity typically vary from 80m long x 50m wide to 100m long x 50m wide1. Stockpiles of this size can be constructed over a reasonable period of time and provide sufficient height and volume required to achieve the preferred level of blending for the brick manufacturing raw materials.

8.3 STOCKPILE CONSTRUCTION – Schedule 5 Condition (4)(d)(i/iv) and (k)

Stockpiles will be constructed to minimise visual and acoustic impacts. Measures taken to achieve this outcome include:

• Shielding of stockpiling operations behind the northern bund to be constructed during site establishment. This will form a visual and acoustic barrier between operations and the residential precinct to the north of the site.

• Height markers will be constructed to indicate the maximum stockpile height of 54m AHD.

1 Numerous variables exist for stockpile lengths and widths.


44

• Use of late model plant with appropriate noise suppression. Specific plant items that have a lower sound rating will be utilised if works are required on stockpiles above 54m AHD. Additionally, works in such areas shall be avoided during morning periods where possible to further mitigate potential impacts on neighbours.

• Location of stockpiles close to the northern bund to maximise noise attenuation. The stockpiles/windrows will preferentially orientated east-west to provide additional noise attenuation to the residents north of the site.

• Stockpiling operations will be minimised in unfavourable weather conditions particularly southerlies.

The construction of stockpiles of brick manufacturing materials will enable blending of the similar types of materials to occur given the various materials are extracted at the various times and from different locations from within the extraction area. The recovery of materials from a stockpile will assist in maintaining a more consistent quality of the raw materials.

Stockpiles of materials will be constructed using scrapers for the first 5m to 6m. Haul trucks and dozers will be used for stockpile construction above the levels completed by the scraper (5m to 6m) up to an additional 2m to 3m with the maximum elevation of all stockpiles being no greater than 54m AHD.

In most cases, the stockpiles will be at least 50m wide to enable the scrapers to turn around within the stockpile footprint rather than traverse the full length of the stockpile. The scrapers will place materials in layers approximately 0.5m thick which will enable the full area of the stockpile to be built up evenly. Care will be taken when the stockpile rises above 2m in height to ensure the edges of the stockpiles are elevated to prevent any rollovers. The stockpiles would have longitudinal slopes of between 7° or 1:8 (V:H) and 14° or 1:4 (V:H) and side slopes typically at the angle of response, i.e. approximately 37° or 1:1.33 (V:H) or slightly greater. It may be necessary at times to remove the approach ramp(s) constructed by scrapers for each stockpile to improve access between stockpiles.

Each stockpile will have height markers to show the 6m level to delineate the limit of the extent of scraper stockpiling permitted. Additionally, markers will be installed to identify the maximum stockpile elevation of 54m AHD.

It is noted that the project approval states at Schedule 5 condition 4 (k) that :

“The batter slopes of all stockpiles must be no more than 1:3 vertical:horizontal, unless otherwise approved by the EPA”

The EPA in correspondence of 11 April 2016 approved the proposed revised batter slopes of stockpiles to 1:1 (V:H) and these slopes have been factored into the stockpile design.


45

8.4 STOCKPILE MANAGEMENT – Schedule 5 Condition (4)(g)

Management of the stockpiles of brick manufacturing raw materials and material required for on-site activities will involve the following.

1. Marking the nominated footprint for the respective stockpiles. The corners of each stockpile area would be marked with a painted 205 litre drum and post together with a sign designating the stockpile number and material type.

2. Materials to be transported off site for brick manufacture will be stockpiled in locations close to the internal road network, whilst those required for on-site uses will be located close to the northern and southern ramps to enable them to be transported to the active operational area, when required.

3. Where practical, it is proposed that for most materials, at least two stockpile areas will be used so that one area can be constructed whilst the other stockpile is being removed.

As discussed in Section 8.3, the boundaries of each stockpile area will be reviewed on a regular basis (e.g. quarterly) to ensure that the areas(s) set aside for each type of materials is consistent with the quantities and material types being extracted. This review would also reflect the extent to which certain types of brick manufacturing materials are being removed from site.

8.5 STOCKPILE SURVEYS – Schedule 5 Condition (4) (i/ii) and (j)

Each stockpile will be surveyed on a quarterly basis to record the quantity and type of materials within each stockpile. The survey will establish the volume of materials expressed in loose cubic metres (lcm). The results of the quarterly survey would be tabulated and a summary presented in each Annual Environmental Management Review.

The results of each quarterly survey will be reconciled against the indicative quantities of materials presented in Table 6. It is noted that the proposed methodology for quality control (see Section 7.1) will dictate the actual quantities of each type of materials stockpiled. Hence, there is likely to be some variance between the actual quantities of materials stockpiled and that listed in Table 6.

9.1 INTRODUCTION

The Project Approval states that the QOMP must "include provision for regular staff or contractor training which is required to be undertaken to reinforce the importance of keeping the types of clay/shale separate". This section of the QOMP deals with this specific requirement as well as other general personnel matters.

9.2 ROLES AND RESPONSIBILITIES

SRC Operations will enter into a commercial contract to supply materials to brick manufacturing companies such as CSR/PGH Bricks and Austral Bricks.

Such arrangements include the appointment of a specialised extraction contractor who will be responsible for the selective mining of each of the specified material types. It is likely that the extraction operations will be deemed to be mining operations for the purposes of the Mining Act 1992. Accordingly, the extraction contractor will also provide a Mine Manager who will be responsible for dealing with all legislative and operational matters relating to extraction operations.

Patons Lane RRC General Manager Operations and Compliance will liaise directly with the appointed Mine Manager in respect of day to day operations and compliance with all relevant aspects of the project Approval.

The contractual agreements appointing the Mine Manager and extractive industry contractor will specifically outline the responsibility of the Mine Manager to comply with the specific requirements of the project approval in relation to:

• stockpile management; and

• maximising the yields of brick manufacturing materials.

9.3 TRAINING – Schedule 5 Condition (4), (h), (i,ii)

Patons Land RRC will be operated in accordance with the Landfill Environmental Management Plan (LEMP) and the Project Environmental Management System (EMS) which has been developed in accordance with relevant Australian Standards.

All staff and contractors will be trained via a site induction process upon engagement and prior to commencement of any work in accordance with the training procedures outlined within the EMS. This training will include details on the importance of keeping clay/shale types separate in accordance with the CoC. The EMS will be updated periodically, as required, based on outcomes of the Annual Environmental Management Review and Independent Environmental Audits.

10.1 EXTRACTION RECORDS

SRC will require the earthmoving contractor to maintain a daily record of the type of materials extracted, the number of loads (in a scraper and/or haul truck) and its destination. This will enable the quantity of materials extracted and stockpiled to be compiled on a daily basis.

10.2 QUARTERLY SURVEY RECORDS

SRC will commission a survey of the Site at the end of March, June, September and December each year to record:

i) the volume of the extraction void beneath a defined level;

ii) the volume of the landfill component;

iii) the volume of all stockpiles of clay and GP Shale retained within the floor of Cell 1; and

iv) the volume of all stockpiles of materials within the northern, central and southern (contingency) stockpiling areas.

This information will be reviewed and compared with the results of the previous quarterly survey and the weighbridge records for the clay/shale materials despatched from Patons Lane RRC.

10.3 OFF-SITE CLAY/SHALE TRANSPORTATION – Schedule 5, Conditions (4), (i/ii) and (i/viii)

The number of trucks departing Patons Lane RRC on a daily basis and the weight of the clay/shale materials transported from the Site for brick manufacturing, or other purposes, will be recorded using the on-site weighbridges. This data will be complied in monthly survey sheets and forwarded to the Department of Planning & Environment (Resources and Geoscience) and the Environment Protection Authority, if and when required.

It is noted that the Division of Resources and Energy will separately require an annual return for the materials extracted on site, i.e. for both the materials to be used on site and transported off site.

10.4 PUBLICATION

A summary of all of the above records will be provided in each Annual Review prepared for Patons Lane RRC in accordance with Schedule 5 Condition 5.
