1 INTRODUCTION
1.1 Background The Dunmore Hard Rock Quarry, owned and operated by Boral Resources (NSW) Pty Ltd, is located at Tabbita Road Dunmore, approximately 12 kilometres north-west of Kiama in the Shellharbour Local Government Area. The quarry produces hard rock which is crushed to produce coarse aggregates and road construction materials, and fines that are used as manufactured sand or bedding material
Development Consent (DA 470-11-2003), issued 19 November 2004 by the Minister for Infrastructure and Planning, allows Boral to produce up to 2.5 million tonnes of hard rock a year (Mtpa), and transport it offsite by road and rail to local and regional markets.
The Development Consent requires the preparation and implementation of a number of management plans to guide the environmental management of the development throughout its operational life. In accordance with Condition of Approval (CoA) 47, a Flora and Fauna Management Plan (FFMP) was prepared by Cumberland Ecology for Boral in 2009. This FFMP incorporated a Vegetation Clearing Protocol, a Compensatory Habitat Management Plan and a Remnant Vegetation Conservation Plan.
Since consent was issued in November 2004, there have been six approved modifications (with conditions), as detailed below:
1. Modification 1 - New Amenities Block -December 2005.
2. Modification 2 - Vegetation Offsets and Transport Route - June 2006.
3. Modification 3 - May 2008.
4. Modifications 4 and 5 - Extension to Extraction Area- November 2008.
5. Modification 6 - Increased Extraction Area and Road Haulage - February 2014.
6. Modification 7 - Proposed Blending Plant – December 2015
To reflect this progression in Dunmore Quarry’s operations, Boral has requested that the existing Flora and Fauna Management Plan be updated, in accordance with the current quarry activities, existing management of vegetated areas and future rehabilitation of the site.
1.2 Project description Dunmore Hard Rock Quarry (the site) covers approximately 248 hectares and is surrounded by private property, predominantly agricultural grazing land and tracts of remnant native vegetation, to the south, north and west (Figure 1). Dunmore Soil and Sand Quarry adjoins the site to the east.
Dunmore Hard Rock Quarry produces hard rock from Bumbo Latite Member, a fine-grained intermediate volcanic rock similar to basalt, which is crushed to produce coarse aggregates, road construction materials and fines. Extraction occurs from three discrete areas: Original Dunmore Quarry, Croome Farm Pit and Rail Infrastructure Corporation (RIC) land (together comprising the extraction footprint). These areas are described in further detail in Section 3.1.
Dunmore Hard Rock Quarry

The extraction method involves drilling and blasting to produce broken rock, that is transported to the primary crusher feed bin. The primary-crushed rock is further reduced in size in a series of crushers, before being conveyed to the tertiary screen house where the crushed rock is sized according to product specifications. The sized products are then stockpiled within the various stockpile areas on site, until they are transported by road and rail to local and regional markets. A detailed description of Dunmore Hard Rock Quarry operations is provided by Environmental Impact Statement for the proposed Dunmore Quarry Production Increase (Corkery & Co 2003).

3 EXISTING ENVIRONMENT
3.1 Site Description The site covers approximately 248 hectares and includes the existing extraction footprint, processing plant, stockpiles of sized products, a workshop and maintenance area, the rail siding and product loading area, administration buildings, carpark and weighbridge (Figure 2). The site also contains a concrete batching plant, which operates under a separate development consent granted by Shellharbour City Council on 4 December 1997. The site is accessed from the Princes Highway via Tabbita Road, a road used solely for access to the quarry (Corkery & Co 2003).
The extraction footprint is surrounded by remnants of native vegetation, separated by expanses of cleared and disturbed grassland. The condition of native vegetation varies between and within remnants, with some areas consisting largely of native plant species and others supporting dense infestations of weeds.
Historically, extraction has occurred in an area known as Original Dunmore Quarry. Extraction operations are currently centred on the Croome Farm Pit and Rail Infrastructure Corporation (RIC) Slot extraction areas (Figure 2).
3.1.1 Original Dunmore Quarry Extraction from the original Dunmore Quarry, located on Boral-owned land, commenced in 1921. The original quarry contains approximately 2.5 million m3 of breccia- agglomerate above approximately 12 Mt of latite in the lower flow. Extraction involves the progressive removal of a breccia-agglomerate (likely to be suitable for production of road pavement materials) and the eventual recovery of high quality latite from the lower flow. There is no limit on the extraction rate from the original quarry.
The existing extraction floor in the original Dunmore Quarry slopes gradually to the east. Elevations of the floor vary from 30mAHD to 60mAHD and there are localised faces where some of the agglomerate has been extracted. The outer faces of the original Dunmore Quarry have been retained to assist in screening exposed extraction faces and stockpiled by-products on the quarry floor (Corkery & Co 2003).
3.1.2 Croome Farm Pit The western area, referred to as Croome Farm Pit extraction area, is owned by Boral. Extraction commenced in this area in 2000, and approximately 12Mt remains in the Croome Farm Pit extraction area. The resource within the Croome Farm Pit extraction area is calculated to the current approved depth of extraction of 107mAHD.
Extraction within Croome Farm Pit will continue to target the upper and middle latite flows. The design of the approved extraction area provides for the creation of three benches in the upper and middle flows in the Croome Farm Pit extraction area. Development Consent No. 168/1994 (am 1) allows an extraction rate of 750 000tpa (Corkery & Co 2003).
3.1.3 Rail Infrastructure Corporation (RIC) Slot The central extraction area referred to as Rail Infrastructure Corporation (RIC) Slot extraction area located on land leased to Boral for which a production royalty is applied to
Dunmore Hard Rock Quarry

any material extracted from this area. Extraction within this area commenced in 1986 with the intent to provide an internal low-level access to the Croome Farm Pit extraction area. Extraction within RIC Slot will continue to target the upper and middle latite flows, with approximately 5 Mt remaining in the RIC Slot extraction area. Development Consent No. 161/1986 allows an extraction rate of 450 000tpa.
The extraction floor levels within the RIC Slot extraction area rise gradually in a westerly direction at about 3% to 4% to meet the horizontal floor (and bench) levels in the Croome Farm Pit extraction area. The extraction faces in the RIC Slot extraction area are typically 15 to 17m high.

3.1.4 Land use The Dunmore Quarry has been operating since 1921, initially by Blue Metal & Gravel Pty Ltd (BMG) and then by Boral from 1982 when BMG’s parent company, BMI Limited, became a subsidiary of Boral Limited (Cumberland Ecology 2009).
The majority of land surrounding the site is owned by Boral and two other quarry companies: Readymix and Dunmore Sand & Soil Pty Ltd. A number of rural properties also adjoin the site. Land use in the surrounding locality includes:
• Agricultural land to the north and south, dairying is the major current agricultural enterprise in the locality (DECCW 2011).
• Commercial and industrial development, including Dunmore Sand and Soil Quarry immediately to the east, and Holcim Australia’s Albion Park Quarry to the north.
• Residential development, including Dunmore Lakes Estate to the south, Shell Cove and Shellharbour to the north-east.
• Infrastructure development, including the Princes Highway and the South Coast Rail Line to the east.
• SEPP wetland no.374a, located on the eastern side of the Princes Highway.
3.1.5 Topography The site is located amongst the undulating topography of the lower slopes of the Illawarra escarpment, on two hills known locally as Locking Hill and Gooseberry Hill. The northern and southern boundaries of extraction activities align with the crests of steep slopes, which have been retained to reduce impacts on visual amenity into the site (Corkery & Co 2003).
The majority of the site has a maximum elevation of approximately 164mAHD, which gradually reduces via a series of quarried landforms to approximately 10mAHD at the eastern margin of the extraction and stockpiling area, and 2mAHD at the weighbridge and office complex (Corkery & Co 2003).
3.1.6 Hydrology Drainage within the site is essentially subdivided into clean runoff from outside the extraction footprint and potentially sediment-laden runoff from within the extraction and infrastructure areas.
The catchment area for potentially sediment laden runoff for the site is defined by the area of disturbance, bund walls and topographic watershed lines. All dirty runoff from site components such as the product stockpile areas, workshop and maintenance area, processing area as well as the extraction area flows into one of three dams: the Croome Sumps, Middle Dam and Lower Dam. A bio-filtration swale is located down gradient of the Lower Dam to aid water quality management when discharging from the Lower Dam. An overview of these dams and the bio-filtration swale is provided in the Water Management Plan. All clean runoff from the site flows into the tributaries of Rocklow Creek which is predominantly dry for most of the year (R.W. Corkery and Co., 2003).

3.2 Significant biodiversity values The Illawarra region within the Sydney Basin Bioregion is one of the most biologically diverse in NSW, and the site and surrounding locality contains the largest remaining patches of native vegetation on the Illawarra foothills and coastal plain (DECCW 2011).
3.2.1 Endangered Ecological Communities The site supports three Endangered Ecological Communities (EECs) listed under the TSC Act. These EECs are known to exist only in the Illawarra region (DECCW 2011). The approximate area of each EEC described below has been calculated following the completion of vegetation clearing for all extensions to the extraction footprint to date.
3.2.1.1 Illawarra Subtropical Rainforest
Approximately 47 hectares of Illawarra Subtropical Rainforest (ISR) occurs within the site, including a large patch that adjoins the southern margin of the extraction footprint and a large patch that is located in close proximity to the northern boundary of the extraction footprint. This EEC occurs most commonly in sheltered gullies generally with a southerly aspect (Cumberland Ecology 2009).
ISR of the site is characterised by dense canopy dominated by Ceratopetalum apetalum (Coachwood), Doryphora sassafras (Sassafras), Backhousia myrtifolia (Grey Myrtle) and a diversity of figs. The abundance of weeds is generally low, with the exception of localised infestations of Lantana camara (Lantana). A species inventory for this EEC is contained within Appendix B of Vegetation Offset Strategy (Cumberland Ecology 2005).
3.2.1.2 Melaleuca armillaris Tall Shrubland
Approximately 21 hectares of Melaleuca armillaris Tall Shrubland (MATS) occurs within the site, generally associated with very shallow to skeletal soils, mainly on the ridges and upper slopes. Patches of this EEC adjoin the northern and southern boundary of the extraction footprint.
MATS on the site supports a low canopy dominated by M. armillaris, a shrub stratum is dominated by L. camara, Prostanthera linearis, Zieria granulata, Leucopogon juniperinus and Phyllanthus gasstroemii and a groundcover dominated by Poa labillardieri, Microlaena stipoides, Bracteantha bracteata, Danthonia spp. and Scaevola albida. Dense lantana infestations are common along the margins of MATS. A species inventory for this EEC is contained within Appendix B of Vegetation Offset Strategy (Cumberland Ecology 2005).
3.2.1.3 Illawarra Lowlands Grassy Woodland
Approximately 37 hectares of Illawarra Lowlands Grassy Woodland (ILGW) occurs within the site, generally associated with lower slopes and some ridges. Patches of this EEC occur to the west and north of the extraction footprint.
ILGW of the site is characterised by a canopy dominated by Eucalyptus tereticornis and E. quadrangulata, a sparse understorey dominated by Acacia mearnsii, Pittosporum undulatum, Notelaea venosa and Alphitonia excels, a shrub layer dominated by L. camara, Croton verreauxii, Phyllanthus gasstroemii, Breynia oblongifolia and Z. granulata and a groundlayer dominated by Oplismenus imbecillis, Microlaena stipoides, Poa labillardieri, and
Dunmore Hard Rock Quarry
14
Delairea odorata. A species inventory for this EEC is contained within Appendix B of Vegetation Offset Strategy (Cumberland Ecology 2005).
3.2.2 Threatened Flora Species
3.2.2.1 Zieria granulata
Zieria granulata (Illawarra Zieria) is a tall shrub or small tree listed as Endangered under both the TSC Act and EPBC Act. This species is known to occur within both MATS and ILGW EECs within the site. In proximity to the extraction footprint, approximately 40 plants were identified within MATS EEC to the north of the extraction while several plants were recorded in the lower part of the Original Dunmore Quarry (R.W. Corkery and Co., 2003). Additional plants were identified to the west of the extract footprint during a site visit undertaken by Arcadis in February 2016. This species likely occurs in other locations throughout the site in associated with ISR, MATS and ILGW EECs.
3.2.3 Threatened Fauna Species No fauna survey has been conducted within the site in recent years. A fauna assessment undertaken by Kevin Mills and Associates in 2003 identified eight mammal species, 73 bird species and three frog species (R.W. Corkery and Co., 2003). No threatened species were identified within the site.
Strategy for the Conservation and Management of Biodiversity in the Dunmore - Shellharbour Hills Area (DECCW 2011) describes the results of several fauna surveys undertaken within the surrounding locality, that are of relevance to the site, and these results are described below.
3.2.3.1 Grey-headed Flying-fox
A camp for the vulnerable Grey-headed Flying-fox, listed as vulnerable under both the TSC Act and the EPBC Act, is located in remnant vegetation south of the site, known as Flying Fox Gully (Figure 3).
Flying Fox Gully is a rainforest gully that is used as a summer camp for the species, and as a maternity camp during the spring and summer, where annual breeding and rearing of young take place. This is one of three maternity camps known in the Illawarra region and the only roost not protected within a conservation reserve (DECCW 2011).
A Grey-headed Flying-fox release cage is located in proximity to this camp (Figure 3), which has previously been used to reintroduce injured and/or orphaned flying foxes to the wild, following their care and rehabilitation. Dunmore Hard Rock Quarry provides assistance to wildlife groups WIRES (Wildlife Information and Rescue Service) and NANA (Native Animal Network Association) that care for the flying foxes.
3.2.3.2 Microbats Five microbat species listed as vulnerable under the TSC Act have been recorded in the locality surrounding the site (DECCW 2011). Surveys undertaken by Gaia Research (2009) recorded the presence of Large-footed myotis (Myotis macropus), Eastern bentwing bat (Miniopterus schreibersii oceanensis) and Greater broad-nosed bat (Scoteanax rueppellii). Eco Logical Australia (2007) previously recorded the Eastern false pipistrelle (Falsistrellus tasmaniensis).

4.1.1 Compensatory Habitat
4.1.1.1 Existing Environment
Compensatory habitat contains four vegetation communities:
• 10.21 hectares ILGW EEC
• 60.34 hectares MATS EEC
• Mosaic of Eucalypt Open Forest and Lantana thickets
• Largely cleared/ Pasture
The site selected for MATS compensatory habitat consists largely of portions of kikuyu and native pasture on a hilltop with dry rainforest and woodland around the lower slopes.
The sites selected for ILGW compensatory habitat consist largely of kikuyu pasture on an area of alluvial soil between the MATS compensatory habitat site to the north and a hill to the south with ILGW on the lower slope.
4.1.1.2 Management Objectives The primary management objectives of the Compensatory Habitat are to:
• Establish at least twice the area of EECs cleared for the quarry extension in nearby areas of modified vegetation, that support similar geology/soil type and landform.
• To improve the connectivity of native vegetation communities by establishing vegetation on land that has previously been cleared for grazing activities. Isolated patches of remnant vegetation will be linked by revegetating areas of cleared grazing (predominantly exotic grassland) land between remnant patches.
4.1.1.3 Past Management Actions A summary of management actions undertaken within compensatory habitat area (see Figure 4) is provided in Table 3.Table 1 Table 3: Management actions already undertaken in compensatory habitat area
Date Action
December 2006 and January 2007
Seed collection and propagation of provenance native plants was undertaken by Southern Bushland Repair.
August 2007
The area of the former ‘Rocklow’ property set aside for regeneration consisted of partially cleared grazing land centred on a rocky ‘knoll’. Following fencing, this area was planted with shrubs and trees, grown from provenance seed collected on or near the site and grown as tube stock at Jamberoo Native Nursery.
Soil was translocated from the area to be quarried prior to December 2007. This soil was repositioned on top of the hill in the compensatory area.
Dunmore Hard Rock Quarry
19
Date Action
December 2007
Tubestock propagated from collected seed were planted by Jamberoo Native Nursery.
February 2008
A preliminary assessment of the high weed growth which had emerged from the translocated soil was undertaken.
Growth and diversity of plant species was measured in 20 x 50 metre quadrats. It was determined that:
• A greater diversity of native plant species (27) than weeds (20) was recorded. These currently cover less than 5% of the area measured. They include numerous ground covers. Three significant colonizing species were recorded. These are: Trema aspera (Poison peach Leaf bush), Acacia sp. (Wattle), and Commersonia fraseri (Brown Kurrajong).
• Planted tubestock are showing vigorous growth and have already attained height dominance (see Table 4.2). At present, they cover less than 5% of the area. Some grazing of eucalypts was observed, but the majority were unaffected. Herbiivores present, as indicated by scats, are wallabies and rabbits.
April 2008
An assessment was carried out at the end of the growing season, to assess the progress of regeneration of native species in the area designated for Melaleuca armillaris tall shrubland regeneration, in the four to five months since planting of tubestock. It was determined that:
• Weeds dominated in the soil translocation area when it was first assessed in February 2008. Twenty weed species were recorded. By late April, although still dominant, weeds were almost all dead or dying.
• On both occasions, a greater diversity of native species (27-30) than weeds (20-21) was recorded. In February, all native species had less than 5% coverage of the area measured. By the end of April, Kennedia rubicunda was covering up to 25% of the area (cover/abundance category 3). Three significant colonizing species present (Trema aspera, Commersonia fraseri and Acacias) had increased in abundance of individuals and in height.
• Natural regeneration, although presently outstripped by weed growth, is occurring in the area treated with soil translocated from the cleared area of Melaleuca armillaris tall shrubland. Steady growth of native colonizing species, especially Brown Kurrajong (Commersonia fraseri), was evident in April.
• Natural regeneration is being prevented by the lush growth of pasture in areas surrounding the MATS regeneration area at the top of the hill. The extent of native grassland is less and the extent of pasture is greater than was originally mapped by Cumberland Ecology in 2005.
• Complete regeneration of native vegetation is unlikely to be achieved in areas where there is a lush growth of pasture grasses, especially kikuyu (Pennisetum clandestinum).
November 2009
Monitoring determined that coverage of tube stock did not exceed 25% across the regeneration area. Height and coverage of natural regeneration had increased. Healthy growth of tubestock which survived initial grazing was continuing. Melaleuca armillaris dominated, with smaller numbers of surviving eucalypts, wattles and other species.
Dunmore Hard Rock Quarry
20
Date Action
Weeds and kikuyu grass continued to dominate the ground layer, although in the area of translocated soil, there was an increasing but still small coverage and diversity of native species.

4.1.2 Remnant Vegetation Conservation Area
4.1.2.1 Existing Environment
The remnant vegetation conservation area contains 33.25 hectares of Illawarra Subtropical Rainforest EEC. Cumberland Ecology (2009) described this EEC as being dominated by Ficus spp. (Fig trees), Dendrocnide excelsa (Giant Stinging Tree), Cassine australis (Narrow-leaved Red Olive Plum) in moister sites, and Backhousia myrtifolia (Grey Myrtle) in drier sites with shallower soil.
Cumberland Ecology (2009) identified weed invasion and degradation of native vegetation resulting from edge effects as potential risks to ISR EEC within the remnant vegetation conservation area
4.1.2.2 Management Objectives The primary management objectives of the Remnant Vegetation Conservation Area are to:
• Remove dense infestations of noxious and environmental weeds, including Lantana camara (Lantana), Araujia sericifera (Moth Vine), Delairea odoratam (Cape Ivy) and Passiflora subpeltata (White Passionfruit).
• Reconstruct ISR EEC in the kikuyu pasture adjoining the south-east of Remnant Vegetation Conservation Area, to protect the existing extent of ISR EEC from edge effects and weed incursions.
4.1.2.3 Past Management Actions A summary of management actions undertaken within the remnant vegetation conservation area to date is provided in Table 5.Table 1 Table 5: Management actions already undertaken in remnant vegetation conservation area
Date Management Action
Summer 2005 Seed was collected from rainforest and eucalypt species on the Rocklow property and in nearby areas of the Illawarra. Tubestock were grown from these seeds at the Jamberoo Native Nursery at nearby Curramore
March 2008 Tubestock were planted into the kikuyu pasture on the slopes above the gully.
Late summer 2008 The heavily weed-infested gully was sprayed with glyphosate.
August 2008
Three 20 x 20 metre quadrats were placed across the profile of gully and adjoining slopes. The site was initially monitored in August 2008, approximately 5 months after planting. Results showed good growth of tubestock, but extensive grazing damage, probably by native macropods (wallabies and possibly kangaroos).
June 2009 The following species (both planted and naturally regenerating) were establishing well across the site: Falcate wattles (Acacia maideni, A.
Dunmore Hard Rock Quarry
24
Date Management Action
melanoxylon, A. implexa), Native Hibiscus (Hibiscus heterophyllus), and Cedars (Toona ciliata, Melia azederach).
Grazing by wallabies was limiting the diversity of other native plant species surviving, both tubestock and natural regeneration, over most of the site. Rapid weed growth was impacting on the survival of tube stock and jeopardizing natural regeneration in the gully area. Significant natural regeneration wass occurring in the gully area.
November 2009
Grazing of tubestock had occurred across most of the site. Maiden’s wattle (Acacia maideni), Blackwood (Acacia melanoxylon), Hickory (Acacia implexa), Native Hibiscus (Hibiscus heterophyllus) and Bracelet Honeymyrtle (Melaleuca armillaris) were surviving well.
Rainforest and other species planted had all been heavily grazed across most of the site. These include Hopbush (Dodonaea viscosa), Ficus spp. especially Sandpaper fig (Ficus coronata), Lilly pilly (Acmena smithii), Red Ash (Alphitonia excelsa), Flame tree (Brachychiton acerifolius), Black wattle (Acacia mearnsii), Gum trees (Eucalyptus tereticornis, E. quadrangulata), Cheese tree (Glochidion ferdinandi), Native Bleeding Heart (Omalanthus populifolius), Flintwood (Scolopia braunii ) and Tea tree (Leptospermum polygalifolium) These were all planted as healthy, vigorous tubestock in top condition.

4.2 Vegetation Clearing A Vegetation Clearing Protocol was required to describe the measures to be implemented prior to the commencement of vegetation clearing in the site. This protocol (Appendix C) was prepared by Cumberland Ecology (2009) and vegetation clearing associated with the approved quarry extension has been completed. No additional vegetation clearing has been undertaken or is proposed for the current operation of Dunmore Hard Rock Quarry. If vegetation clearing is required it will be conducted generally in accordance with the Vegetation Clearing Protocol prepared by Cumberland Ecology (2009).
4.3 Rehabilitation Extraction of hard rock from Dunmore Hard Rock Quarry will substantially modify the existing landform within the site. Following the completion of quarrying activities (or progressively once activities have ceased in particular sections), the quarry will be recontoured and revegetated. Recontouring and revegetation is outlined in the Rehabilitation Plan (Arcadis 2016). The Rehabilitation Plan has been developed in accordance with Condition of Approval 3(54).

5 MONITORING, REPORTING AND REVIEW
5.1 Monitoring Flora and fauna management actions will be measured through regular environmental performance reviews. These will be based on the future management actions outlined in:
• Section 4.1.1.4: Compensatory Habitat Area (Table 4).
• Section 4.1.2.4: Remnant Vegetation Conservation Area (Table 6).
• Section 4.1.3.4: Offset Area (Table 8).
The reviews will be used to assess progress in meeting project environmental objectives and targets and will be undertaken by the Environmental manager:
• In response to new or revised Boral Project approvals.
• In response to major changes in site conditions or work methods.
Boral environmental performance is measured through compliance with the plans listed above, in addition to other environmental plans such as the Water Management Plan.
Should an environmental non-conformance be identified as a result of a monitoring result, a non-conformance report will be completed and archived by the Environmental manager.
5.2 Reporting Reporting on the implementation of this Plan would include the following:
• The results of all environmental surveys and monitoring, including adequacy of site-specific environmental safeguards and management measures
• Any community/stakeholder complaints or non-conformances with licences/criteria, including any responses provided or actions undertaken in response to the complaint or non-conformance
• Any remediation actions or changes to management and mitigation measures.
5.2.1 Annual Review The results of the monitoring program will be presented in the Annual Review (AR). This will include detailed assessment of monitoring results collected over the course of the annual monitoring program, an evaluation of any trends occurring across the site, and recommendations for management action. Through the AR management actions may include:
• Refinement of flora and fauna management objectives and initiation of remedial action
• Alteration to monitoring frequency, parameters or locations
Dunmore Hard Rock Quarry
39
5.3 Review
5.3.1 Review of Monitoring Actions Any non-compliance identified during monitoring actions, of management and mitigation measures, will be highlighted and an environmental incident report will be completed. The non-conformance will be considered unresolved until:
• The non-compliance issue has been resolved;
• A new or revised procedure has been established and implemented;
• Training has been provided to relevant personnel/ sub-contractors; or
• Additional specific environmental management inspections are detailed in this flora and fauna management plan.
5.3.2 Review of Management Plan This Plan will be reviewed on the following basis:
• Every 12 months to ensure its continuing effectiveness
• Where an audit recommends a review

6 TRAINING
6.1 Environmental induction Environmental induction training will be delivered to all staff and subcontractors involved in the Project. This will be delivered by the relevant Boral personnel (e.g. Environmental manager). This will include a component on environmental/what this Plan is for management and the associated controls and mitigation measures that will be implemented for the Project. All personnel will be required to sign an induction sheet, a copy of which will be maintained on site and appropriate records maintained.
Appropriate training and induction should include, but not be limited to:
• Raising awareness of on-site environmental management issues;
• Providing information on the location and importance of EECs, threatened flora and fauna species (and habitat) known to occur within the site;
• Providing information on the current and proposed management practices within the Compensatory Habitat area, Remnant Vegetation Conservation area and Offset area.
• Providing information on the boundaries for any proposed vegetation clearing;
• Training on procedures on encountering fauna (e.g snakes); and
• Training on weed identification and the appropriate guidelines for removing weeds, driving vehicles in weed infested locations and the disposal of weed infested topsoil.
6.2 Site-specific environmental training Where identified by the Environmental manager, additional site-specific training may be developed and implemented by the Project manager, delivered to relevant personnel/contractors as required regarding sensitive environmental issues. Specific training may include:
• Training in the use and location of spill kits
• Management, and environmental incident response training.
6.3 Environmental Incident Register A environmental incidents register will be maintained by the Environmental manager and will include any outcomes from incidents. These will feed into the inductions, toolbox meetings and pre-start meetings as necessary and appropriate.

7 CONTINGENCY PLANNING
7.1 Emergency incident plan An emergency incident plan will also be developed to respond to uncontrolled discharges of fuels, oils and chemicals/unforeseen events.
Response procedures for protection of the water environment will aim to:
• Contain and control emergency incidents
• Safeguard people on-site and offsite
• Protect drainage paths and waterways
• Minimise damage to the environment and property
• Identify appropriate disposal techniques for contaminated soils and water
• Facilitate remediation of the environment.
Suitable containment and clean up materials will be maintained within easy and quick access.
All reporting will be in accordance with Boral’s incident reporting management system. Similar complaints will be addressed through the site complaints register. Compliance with statutory requirements will be assessed through implementation of Boral’s site audit program that is aligned to ISO 19011:2003. Results of the above mentioned aspects will be used to ensure appropriate corrective actions are in place and to verify appropriate close out actions, follow up and reporting has occurred.

ANNEXUREC
MANAGEMENT SCHEME FOR THE CONSERV ATION AREA
The conservation values identified in Annexure B are to be managed in accordance with the principles and activities outlined below.
ITEM 1: The following activities may be undertaken on, or in respect of, conservation area part 1 and conservation area part 2 (as relevant) in the manner specified as follows:
Weed control a) Carrying out weed control using the appropriate control methods below and in accordance with
the Dunmore Quarry Flora and Fauna Management Plan. • Use glyph ate based herbicide by direct application to cut surfaces (cut and paint or scrape
and paint method ) and targeted spraying. This should be limited to according to the directions on the label and en uring that there is no off-target damage.
• Using appropriate control measure a recommended in the Department of Industry and Investment Noxious and Environmental Weed Control 4th Edition 2009 or equivalent replacements for control of weed , ensuring minimal off target damage.
• Remove weeds by hand ensuring that all plant parts which can reproduce are removed and that soils do not become prone to erosion.
• Other weed control methods may be undertaken with prior written permission of the Director-General.
• Ensure control programs are commenced when timing and extent of weed removal will minimise adverse effects on wildlife (weeds may provide protection or habitat for native fauna).
• Ensure removal of lantana is not undertaken during nesting periods for small birds which nest in lantana stands.
• Continue to check for weed invasion and regrowth and treat any outbreaks. • Check adjacent areas and gardens for invasive plant species and remove, or control their
spread.
Feral animal control b) Monitoring impacts to the conservation area by pest animals and undertaking of on-going control
programs for feral animals if appropriate. • Methods for monitoring pest animal activity can include;
o observations and/or hearing calls, o the use of standard "sand plots", o the use of non-poisoned "bait stations", o scat counts, and o other quantitative techniques which can be designed in discussion with the Department
or the Livestock Health and Pest Authority
• Methods for control can include shooting, trapping and use of poisonous baits consistent with advice from the Department and the Livestock Health and Pest Authority.
• Participate in community pest animal control programs, and encourage neighbours to implement pest animal control programs.
Bora! Resources (NSW) Pty Ltd Initials ofDi",(o,,: tf! t#I 23
Conservation Agreement , Dunmore Quan'Y
Fire c) Suppression of all wildfires occurring in conservation area as quickly as possible with the aim of
keeping fires to a small area.
d) Undertaking of fire hazard reduction to protect the natural assets of conservation area, III
appropriate locations, with any required approvals and/or permits using: • raking and hand clearing; • pile burning; or • fuel reduction burns.
e) Using fire hazard reduction bums and controlled burning which take into account the recommended fire intervals given in the Bush Fire Environmental Assessment Code for New South Wales (Rural Fire Service February 2006) and the guidelines contained in the Threatened Species Hazard Reduction Lists for the Bush Fire Environmental Assessment Code or equivalent replacements.
Current recommendations are: Melaleuca armillaris Tall Shrubland: No fire more than once every 10 years Illawarra Lowland Grassy Woodland: No fire more than once every 5 years for grassy

Vegetation Clearing Protocol
The Vegetation Clearing Protocol (VCP) will:
delineate the areas of remnant vegetation to be cleared; and
describe the procedures that would be implemented for:
pre-clearance surveys;
progressive clearing;
fauna management;
conserving and reusing topsoil;
collecting seed from the site;
salvaging and reusing material from the site; and
controlling weeds.
The Vegetation Clearing Protocol will provide details about the conservation and
management of the topsoil and constituent seed bank, the duration of topsoil storage and
the locations for temporary storage of topsoil. Such locations will be determined in
consultation with the Boral Quarry Manager.
4.1 Identification of remnant vegetation to be cleared
Ground truthing confirmed that the extent of Melaleuca armillaris Tall Shrubland was 2.3ha
and the area of the Eucalyptus tereticornis – E. quadrangulata Open Forest was 4.1ha in
the approved Croome Farm extension. Thus the area of compensatory habitat required
for this extension is 4.6 Ha for Melaleuca armillaris Tall Shrubland and 8.2 Ha for Illawarra
Lowlands Grassy Woodland (Eucalyptus tereticornis – E. quadrangulata Open Forest).
The offset for the extension into the RailCorp Land has been identified as a designated
area within Appendix 3 of the Consent Instrument. This Central Vegetation Offset includes
an 8ha active management zone containing Melaleuca armillaris Tall Shrubland in which
weed control and supplementary plantings will be undertaken.

4.2 FINAL REPORT BORAL

4.2 Pre-clearance Surveys
Vegetation and topsoil removal will be undertaken within the Approved Quarry Extraction
(AQE) area in small stages each covering 2ha.
The boundaries of each vegetation community to be cleared at each stage must be
identified prior to removal and clearly delineated with high visibility markers for easy
identification by quarry staff and/or contractors engaged in the clearing operation.
Targeted surveys for threatened fauna will be conducted prior to each stage of clearing for
the approved quarry extension (see protocol Table I.1, Appendix I).
The aims of the pre-clearance fauna surveys are to:
Document food trees to be removed if threatened species are found to utilise
these trees on the site.
Check hollow bearing trees for signs of breeding of threatened species
Detect roosting and breeding sites of threatened species ;
Detect any individual threatened species in path of clearing and remove from
disturbance area to minimise risk of injury
4.3 Progressive Clearing
At each stage of vegetation and topsoil removal in the Approved Quarry Extension,
clearing cannot proceed until boundaries of the endangered ecological communities have
been clearly marked and observed threatened fauna have been evacuated from the site.
Clearing activities will be confined to demarcated areas. Vegetation and topsoil removal
from each of the two vegetation communities identified on the site will require separate
treatment according to how the various components will be used in the Compensatory
Habitat Management Plan (see below).
4.4 Fauna Management
Fauna management procedures are set out in Capture / Observation Procedures for Pre-
clearing Survey Appendix I, Table I.2. Clearing cannot proceed until observed threatened
fauna have been evacuated from site.
The recommended procedures set out a protocol to deal with live, injured or dead
threatened species recorded during the pre-clearance surveys:

Encourage tree roosting threatened species to move from roost early morning
prior to clearing
Monitor roost for up to one week to allow bats to vacate of own accord if
possible. Progressively block access to hollows after bats depart for night
time feeding.
If threatened species are found nesting in the site inform Environmental Officer
and establish a buffer around nest site until the nest is vacated by adults and
young.
Contact local carer for injured threatened species.
Capture injured animal (by qualified and immunised personnel) and hold in a
cotton lined bag which is to be kept in a quiet, warm dark place until it is given
to carer.
Prepare and forward dead specimens of threatened species to museum if
appropriate.
4.5 Conserving and Reusing Topsoil
Soil underlying M. armillaris vegetation in the quarry extension area is very shallow to
skeletal with surface rock making topsoil retrieval difficult. As far as possible, shallow soil
and surface rock will be retrieved after removal of M. armillaris shrubland vegetation. This
material will be transported and spread immediately on the prepared site in the CHMZ.
Mulched M. armillaris vegetation will be spread over translocated topsoil.
In the more heavily Lantana infested areas (especially under the open forest) where soil
thickness exceeds 0.2m, it will be pushed into windrows by a bulldozer and loaded into
haul trucks with a front-end loader. The topsoil recovered to date in the Croome Farm
extraction area has been used to assist in the revegetation of the acoustic bund wall that
has been constructed progressively southwest of the Croome Farm extraction area. Any
excess topsoil from the Croome Farm extraction area would be stored in the original
Dunmore Quarry until it is needed for revegetation activities. Soil stockpiles are typically
less than 1.5m high and are allowed to regenerate naturally to limit erosion and generation
of sediment-laden runoff.

4.6 Collecting Seed from the Site
An important component of the Compensatory Habitat Management Plan is the
reconstruction/fabrication of an area equivalent to twice the area of the endangered
ecological communities to be removed for the approved Croome Farm extension. The
chances of successful establishment of a self-sustaining ecological community in the
compensatory habitat areas are greatly enhanced by introducing a diverse range of locally
sourced seed or seedlings that are representative of the vegetation communities into sites
closely matched for soil type / geology and position in landscape. Since all the vegetation
will be cleared on the quarry extension site, as much seed as possible should be collected
from the site prior to and during clearing. During clearing it is easier to collect seed that
was previously inaccessible.
Field reconnaissance will need to be conducted to determine the exact location of target
seed populations. The location of individual plants may need to be marked on maps or by
using a handheld Global Positioning System (GPS).
FloraBank20
has produced guidelines for collecting seed from native vegetation for use in
revegtation programs. Seed collecting from the quarry extension site should be carried
out by suitably qualified personnel familiar with local species, flowering, fruiting and
seeding times and correct collecting, storage and treatment methods.
4.7 Salvaging and Reusing Material from the Site;
4.7.1 Melaleuca armillaris Tall Shrubland
Vegetation from Melaleuca armillaris Tall Shrubland with low levels of Lantana infestation
will be removed from the extraction areas and transported and spread immediately to the
offset sites for MATS fabrication. Smaller branches will be mulched and spread on the
CHMZ-MATS site.
4.7.2 Illawarra Lowlands Grassy Woodland
Vegetation from Illawarra Lowland Grassy Woodland with low levels of Lantana infestation
will be removed from the area to be developed for extraction and transported immediately
to the CHMZ and temporarily stockpiled for ILGW reconstruction. Smaller branches will be
mulched and spread on the CHMZ-ILGW site.
4.8 Controlling Weeds
Vegetation from Melaleuca armillaris Tall Shrubland with moderate to high levels of
Lantana infestation will be removed by a bulldozer pushing and stockpiling the pushed-up
trees and shrubs beyond the limits of the extraction stage being cleared. The vegetation

removed will be stockpiled on the margins of the active extraction area and within the
regeneration area west of the Croome Farm extraction area for use in rehabilitation works
The vegetation from Illawarra Lowlands Grassy Woodland with moderate to high levels of
Lantana infestation will be removed by a bulldozer pushing and stockpiling the pushed-up
trees and shrubs beyond the limits of the extraction stage being cleared. The vegetation
removed to date has been stockpiled on the margins of the active extraction area and
within the regeneration area west of the Croome Farm extraction area for use in
rehabilitation works in conjunction with the rehabilitation plan for the Project Site. None of
the vegetation will be burnt.
4.9 Summary of mitigation measures for vegetation clearing
