1.0 INTRODUCTION
1.1 PURPOSE OF DRAFT EMP
The Draft Environmental Management Plan (Draft EMP) is part of the Environmental Impact
Statement (EIS) for the proposed Gold Coast Quarry (GCQ) and its purpose is to provide a range
of measures for implementing any environmental management strategies that have been
presented in the EIS. On approval of the GCQ, the Draft EMP will be revised to become the EMP
that specifies environmental management requirements and procedures for the life of the Quarry.
Revision of the Draft EMP is necessary to include provisions of any environmental conditions
which are attached to the approval.
The Draft EMP provides documentation of the proposed environmental management objectives
and implementation strategies for the benefit of:
Boral staff who will be responsible for the management of the quarry including its
environmental performance;
Contractors who undertake specific tasks, particularly during construction, on behalf of
Boral;
Government regulators who need to be able to confirm that practical strategies have
been put in place for achieving environmental objectives;
Consultants who undertake environmental monitoring and auditing;
Community groups, to confirm protection of environmental and social values; and
Members of the public who may download the Draft EMP for reference purposes.
1.2 DOCUMENT STRUCTURE
A recommended structure for the draft EMP was specified in the Terms of Reference for the GCQ
EIS. More explanatory information on the recommended structure is available from a document
titled Guideline for Preparing Environmental Management Plans, which was prepared by the then
Queensland Environmental Protection Agency.
The EMP structure provides a recommended standard set of headings which provide a
framework for setting goals and prescribing management actions for each topic or element. The
generic framework for EMP topics is presented in Table 1 below.
Ref: B12119ER002RevB-Draft EMP - 6 - Draft EMP – BORAL Gold Coast Quarry
Table 1 Generic EMP Topic Structure
Heading Contents
Element/Issue The aspect of construction or operation to be managed (as it affects
environmental values). Includes a brief description of the topic drawn
from the EIS or EIS technical reports, including any potential issues
which have been raised.
Operational policy The operational policy or management objective that applies to the
element.
Performance criteria Measurable performance criteria (outcomes) for each element of the
operation.
Implementation strategy The strategies, tasks or action program (to nominated operational
design standards) that would be implemented to achieve the
performance criteria.
Monitoring The monitoring requirements to measure actual performance (e.g.
specified limits to pre-selected indicators of change).
Auditing The auditing requirements to demonstrate implementation of agreed
construction and operation environmental management strategies and
compliance with agreed performance criteria.
Reporting Format, timing and responsibility for reporting and auditing of
monitoring results.
Corrective Action Corrective actions may be stated where site specific measures are
required, otherwise corrective actions will be according to the Boral
Integrated Environmental Management System.
Reference Documents Identifies important source documents if any
1.3 DOCUMENT CONTROL
A Draft EMP is part of the EIS process and may not be updated until the conclusion of the EIS
process. The EMP which is derived from the Draft EMP will be a controlled document, meaning
that all copies of the document that are used for managing the daily operations of the quarry will
be updated whenever the master copy of the EMP is updated. An EMP is a site specific
document however it will generally be aligned with Boral’s Integrated Environmental Management
Systems (IEMS), which covers all sites and all activities. To reduce the need to continually
Ref: B12119ER002RevB-Draft EMP - 7 - Draft EMP – BORAL Gold Coast Quarry
update the EMP, items which are likely to be subject to change should be contained within
external documents which can be easily updated and which are referred to by the EMP.
1.3.1 APPROVAL
The Draft EMP will be submitted to the Coordinator-General for assessment as part of the EIS. If
the project is approved, the implementation strategies in the Draft EMP may form part of the
approval.
1.3.2 DISTRIBUTION
Once the EIS has been prepared to the satisfaction of the Coordinator-General, a public notice
will be advertised in relevant newspapers circulating in the region and nationally. The notice will
state where copies of the EIS can be viewed or purchased, the submission period, and where
submissions should be sent. Via this process, the Draft EMP will become a public document.
The master copy of the EMP is to be maintained at Boral’s corporate offices. Site copies are to
be distributed to site offices and a distribution record is to be maintained.
1.3.3 AMENDMENT
As the EMP specifies the implementation of approval conditions, amendments to any issues that
would affect capacity to meet approval conditions may require regulatory approval. Amendments
to any other matters within the EMP must be consistent with any development conditions that are
in force. Due to changes in the regulatory environment and in environmental monitoring and
management technologies, amendments will need to be made over time. Regular review and
amendment of the EMP is necessary to ensure the EMP remains relevant and implementable.
This Operational EMP is subject to periodic updates, it will be a controlled document under
Boral’s quality management system to ensure that only the current version is used to guide
operations and that superseded versions are removed from use. Version numbers will be clearly
displayed on any printed copies and the current version number and revision register will be
maintained in the master copy.
Copies of the EMP which have been downloaded from the internet will be uncontrolled copies
and may become superseded as new revisions are issued.
1.4 SCOPE
The Draft EMP covers the construction, operation and eventual decommissioning of the proposed
GCQ. All site works including operations undertaken by the Principal and any contractors and
sub-contractors are to be in accordance with the EMP in force at the time.
Ref: B12119ER002RevB-Draft EMP - 8 - Draft EMP – BORAL Gold Coast Quarry
1.5 RELATED MANAGEMENT PLANS
A number of specialised management plans may be required by regulators under approval
conditions. Findings and recommendations from these plans have been incorporated into the
Draft EMP where possible. It will be necessary to review the other plans to ensure that all
requirements are understood before undertaking management activities that may be covered by
one of these plans or covered by this EMP. Some areas of overlap will occur and more stringent
requirement should prevail, which in most cases will be in the specialised plan. Expected/known
specialised management plans include:
Blasting Management Plan;
Bushfire Management Plan;
Construction Environmental Management Plans;
Erosion and Sediment Control Program;
Lake Water Quality Management Plan;
Stormwater Management Plan;
Vegetation Management Plan;
Waste Management Plan; and
Wildlife Management Plan.
1.6 PERFORMANCE REQUIREMENTS
Performance requirements for some matters contained in this Draft EMP will depend on
conditions stated in the development approval and other negotiated agreements and will need to
be written into the EMP once they become known.
Other performance requirements originate from Commonwealth legislation, Queensland
Government legislation (Acts and Regulations) and the Gold Coast City Planning Scheme. A
review of legislation applicable at the time of writing is provided within the EIS.
Items that are not explicitly covered by an Act will be considered to be covered by the general
environmental duty (defined under the Environmental Protection Act 1994) that requires
companies and individuals to minimise environmental harm.
Ref: B12119ER002RevB-Draft EMP - 9 - Draft EMP – BORAL Gold Coast Quarry
2.0 PROJECT DESCRIPTION
Boral is proposing to establish a new extractive industry operation on a greenfield site, Lot 105 on
SP144215 at Old Coach Road, Reedy Creek as shown in Figure 1, below.
Figure 1 - Location Map
Ref: B12119ER002RevB-Draft EMP - 10 - Draft EMP – BORAL Gold Coast Quarry
The project is necessary to compensate for the scheduled winding down of Boral’s existing West
Burleigh Quarry, which has sufficient reserves for only a further 6.5 to 9 years of production
(depending on market conditions). Given the lead times that are involved (in gaining development
and environmental approvals; establishing the operation and completing preliminary site works in
order to enable full scale production), it has been necessary for Boral to commence the relevant
approval processes to ensure that an adequate, uninterrupted and efficient supply of construction
materials remains available for critical infrastructure and construction projects in the Gold Coast
region.
The Gold Coast Quarry will represent an investment of $140-$160million (2012[1] dollars) by Boral
into the economy of the Gold Coast region and is projected to provide continuity of employment
for approximately 100 staff across Boral’s integrated quarrying, asphalt, concrete and transport
operations. An estimated total of 246 full-time equivalent (FTE) person-years will be directly
required for the development and on-site construction of the project. The flow-on benefits of this
employment would generate further employment opportunities for the wider Gold Coast region
and Queensland, resulting in a total of approximately 480 and 490 full-time equivalent person-
years, respectively. Once operational, the proposed Gold Coast Quarry would directly generate
24 FTE positions. The flow-on benefits of this employment would support about 65 FTE positions
in Queensland, with 62 positions generated in the Gold Coast. The proposed Gold Coast Quarry
would provide a net increase in employment opportunities and help continue quarrying industry
jobs within the area once the West Burleigh Quarry resources are exhausted.
The proposed Gold Coast Quarry contains the last and largest known deposit of meta-greywacke
quarry rock resources on the southern Gold Coast. Meta-greywacke is of extremely high strength
and forms the excavated and processed quarry product. The meta-greywacke resource is located
within a deposit that is favourably surrounded by ridgelines and has the benefit of having
substantial vegetated buffers on land owned by Boral. In developing this proposal, Boral has
balanced the need to secure and develop this hard rock resource with the social and
environmental factors associated with extractive industry development. After taking into account a
range of environmental constraints and providing appropriate separation buffers during the
detailed design process for the proposed quarry footprint, it has been estimated that a total of 79
million tonnes of measured, indicated and inferred quarry resources have been delineated on the
site (within the optimised pit shell and including the area to be developed for the plant and
associated infrastructure). Boral has voluntarily sterilised a significant proportion of the resource
which is known to occur on the site in order to achieve an appropriate balance between
environmental, economic and community interests.
[1] Based on the value of the Australian dollar during 2012
Ref: B12119ER002RevB-Draft EMP - 11 - Draft EMP – BORAL Gold Coast Quarry
The proposed development will operate as a quarry for the extraction and processing of hard rock
primarily for use in concrete, asphalt, drainage materials, road base, bricks/blocks, pavers, pipes
and landscape supplies. Investigations confirm that the quality and consistency of the resource at
the site is of equal or better quality than the meta-greywacke deposit situated at Boral’s existing
West Burleigh Quarry, providing an opportunity to completely replace the current quarry
operations at Boral’s existing West Burleigh Quarry. The proposed Gold Coast Quarry will supply
the Gold Coast region with high grade construction materials for at least another 40 years, whilst
maintaining continuity of employment across Boral’s integrated quarrying, asphalt, concrete and
transport operations.
The greenfield site will be fully developed and operated in accordance with recognised industry
best practice. Initial development requires the removal of significant overburden quantities over
the first few years of site development, including the introduction of mobile crushing plants to
develop the site and value the excavated material. Boral estimates that approximately 5-6 million
tonnes of materials (all types) will be removed from the site to allow the site infrastructure and
fixed plant to be built.
Overall, the proposed Gold Coast Quarry’s processing plants and supporting heavy mobile
equipment (HME) will comprise:
Mobile Crushing Plants
Proprietary modular trains from recognised (best practice) manufacturers such as Sandvik or
Metso. The 3-stage road base train consists of a Primary Jaw, Secondary and Tertiary Cone
Crushers complete with screens, conveyors and stockpiling conveyors. The second train (for
aggregates production) will be the same or similar to the first and may include a vertical shaft
impactor (VSI) to improve aggregate quality for use in higher specification applications. Each train
will be targeting to achieve a minimum of 300 tonnes per hour of aggregate or base course
materials. The estimated capital cost of each train is $6 million (2012 dollars).
Fixed Plant
The plant will be designed as a modern, ‘fit for purpose’ crushing plant which will target the
production of aggregates. It is estimated that the production rate will be between 750 - 900
tonnes per hour to achieve an annual production of 2 million tonnes. The estimated cost of the
plant is $75 million with a construction timeframe of 18-24 months.
Mobile Fleet
There will be two distinct fleets, firstly a development fleet which will service the site development
and stripping works, through to load and haul service for the mobile crushing trains. The second
fleet will be sized to service the 750-900 tonne per hour fixed plant. Over the course of the
establishment and operation of the project, there will be a range of equipment on the site for
various periods of time (refer to Table 1). This equipment includes the following:
Ref: B12119ER002RevB-Draft EMP - 12 - Draft EMP – BORAL Gold Coast Quarry
Excavators;
Graders;
Front-end Loaders;
Bulldozers;
Compactors;
Articulated Dump Trucks;
Water Trucks;
Haulage Trucks; and
Cranes.
2.1.1 THE QUARRY PROCESS
The quarrying process commences with a survey of the rock face and bench to be developed (by
drilling and blasting). Laser survey equipment defines the rock mass, and an optimised blast hole
pattern is designed, and drilled. As production requirements demand, the drilled “shot” is then
charged with bulk explosives, and fired, in accordance with the site blasting model and
procedures.
Once the rock has been blasted, fragmented rock will be loaded from the pit floor onto haul
trucks, whereas any larger rock fragments (“oversize”) will typically be broken by a rock breaker
before loading. The load and haul fleet will generally be operated continuously during the
operating hours of the quarry, in order to maintain continuity of supply for processing.
The primary stage of processing involves the use of a jaw crusher and vibratory screens, with
crushed product being held in an interim stockpile called a “surge pile”. From this stage, material
will be conveyed to several downstream stages of crushing and screening equipment. After
processing, the material will be conveyed to individual product stockpiles. The processing plant,
including primary and secondary crushers (and screens to separate dust and aggregates) will be
located within the plant and infrastructure area, near the individual product stockpiles.
The quarry materials are then either loaded directly by a front end loader (‘sales loader’) from the
stockpiles, or via overhead storage bins at the plant (under typical conditions), to road haulage
trucks. The road haulage trucks then proceed across the weighbridge and through the wheel
wash before exiting the site to deliver quarry materials to the market.
Chapter 2.0 of the project EIS provides a more detailed description of the various components of
the project.
Ref: B12119ER002RevB-Draft EMP - 13 - Draft EMP – BORAL Gold Coast Quarry
2.2 STAGES OF DEVELOPMENT
The site will be developed in a sequence of discrete stages. Each stage will involve a series of
phases:
Site establishment (‘E’), development (‘D’), and construction (‘C’) stages (featuring a
number of intermediate phases);
Quarry operation (‘Q’) stage (featuring a number of phases) associated with the
development of the quarry pit itself; and
Rehabilitation and decommissioning of the site once the operations have concluded.
The timing and rate of progression through the stages associated with the pit development will be
defined by market conditions and demand. It is not appropriate to specify timeframes for the
development of each respective phase of the project at this early point, but the quarry will have
an operational life of at least 40 years.
During the construction and site preparation stage, the proposed Gold Coast Quarry will operate
with mobile plant(s), and be replaced with a permanent fixed plant as soon as practicable after
the plant site infrastructure area and initial pit have been established (estimated to occur between
years 4 and 5 of the approved development).
The staging plans for the project, as prepared by Lambert & Rehbein detail how the development
of the quarry is intended to progress (refer to Appendix C). Table 2, below, provides a general
overview of the works that will be undertaken as part of each phase of the development stage.

Ref: B12119ER002RevB-Draft EMP - 16 - Draft EMP – BORAL Gold Coast Quarry
2.3 LAND OWNERSHIP
The land that is the subject of this EIS comprises Lot 105 on SP144215 and Lot 901 on
SP907357.
Lot 105 on SP144215 is a freehold title that is in the ownership of Boral Resources (QLD) Pty
Limited. The current title search for this particular parcel confirms that Lot 105 is not benefitted or
burdened by any existing easements.
Lot 901 on SP907357 effectively bisects Lot 105. Lot 901 traverses the site generally in a south-
east to north-west direction between Tallebudgera Creek Road and Chesterfield Drive and it is a
reserve administered by the Council of the City of the Gold Coast as a trustee. The current title
search for this parcel also confirms that this allotment is not benefitted or burdened by any
existing easements.
The project does not rely on Lot 901 on SP907357 for any part of the construction and future
operation of the quarry.
The EIS demonstrates that the project will be undertaken entirely within the portion of Lot 105 that
is situated to the north of Lot 901 on SP907357. Refer to Map 1 in Appendix E.
2.4 MAJOR INFRASTRUCTURE REQUIREMENTS
The proposed development does not require connection to the Council’s trunk water, sewer or
stormwater infrastructure systems. The project will be entirely self-sufficient with respect to these
aspects.
The development will need to connect to the necessary electricity and telecommunication
services.
Ref: B12119ER002RevB-Draft EMP - 17 - Draft EMP – BORAL Gold Coast Quarry
3.0 APPROVAL CONDITIONS
As the Draft EMP has been prepared prior to the issue of a Decision Notice, this section will
require revision once Approval Conditions become known.
3.1 EXTRACTION AREA
The limit of the extraction area is defined in the EIS. As the GCQ is surrounded by residential
areas, the proponent has voluntarily limited the area of extraction to a central area that affords
topographical shielding from residential areas and considerable buffer distances around
operational areas.
The disturbance area and extraction areas will be clearly indicated on quarry development plans.
3.2 ACCESS ROAD
Access to the GCQ for quarry-related traffic will be via an entrance to the quarry to be
constructed off Old Coach Road. Intersection works will be undertaken to provide turnouts for
trucks and to improve sight lines.
Access from the Tallebudgera Creek Road frontage will be minimised and no road works or track
development works are planned. However there may be circumstances in which limited access to
this area may be necessary such as for fire control. Other potential requirements might include
fence maintenance, water monitoring and environmental management such as weed control.
3.3 OTHER CONDITIONS
This section will provide information on limits to activities imposed by approvals notice and other
regulatory instruments, when the EMP is finalised.
Ref: B12119ER002RevB-Draft EMP - 18 - Draft EMP – BORAL Gold Coast Quarry

5.3 COMMUNITY CONSULTATION
5.3.1 ELEMENT/ISSUE
Quarrying operations can impact on the quality of life, economic and environmental values of
surrounding lands. Dust, noise and traffic impacts are among the most frequent sources of public
concern. Whilst the EIS consultation process ensures that all likely impacts have been
considered and appropriately mitigated, there is a need to establish channels of communication
that operate during the life of the quarry with potentially affected stakeholders. Topics that need
to be communicated include basic information about the proposed quarry operation, how key
areas will be managed to reduce impact on human and natural environment. Opportunities for
Ref: B12119ER002RevB-Draft EMP - 25 - Draft EMP – BORAL Gold Coast Quarry
people to present questions about how the proposed quarry will impact on matters that concern
them also need to be provided.
This topic covers proactive engagement with the community. Any complaints received outside
the consultation process should be handled via the procedures in the complaints management
topic.
5.3.2 MANAGEMENT PLAN
Operational Policy Objective – Community Consultation
Residents and other stakeholders potentially impacted by quarry-related activity are informed of the development of the quarry in advance of site development.
Performance
Criteria
Potentially adverse impacts to the community or the environment, or
perceptions to that effect, which are identified by members of the
community are properly reported to the staff within Boral who have the
authority to mitigate the unnecessary impact/perception of impact.

5.4 EROSION AND SEDIMENT CONTROL
5.4.1 ELEMENT/ISSUE
Erosion of sediment from the development area would lead to water quality objectives for the site
not being met as the sediment load of water draining from Lot 105 would increase.
An Erosion and Sediment Control Program (ESCP) has been prepared for the establishment,
development and construction phases of the project. The information provided below is a subset
of the information in the ESCP and is provided for information purposes.
All works that are undertaken outside the footprint of the ESCP such as clearing for security
fences or fire trails will abide by the policies laid out in the ESCP where relevant and any
applicable implementation strategies.
5.4.2 MANAGEMENT PLAN
Operational Policy Objective – Erosion And Sediment Control
Sediment generation should be minimised and sediment contained within operational areas
Performance
Criteria
Water from disturbed areas must flow through effective sediment
capture devices before entering surrounding environment.
Implementation
Strategy
Any upstream ‘clean water’ surface flows will be diverted around the
boundaries of the earthworks area via diversion berms constructed for
this purpose;
Installation of treatment devices as per Erosion and Sediment Control
Program drawing Nos. B12119-SK-350 to 355;
Ensure that any sediment-laden surface runoff from Lot 105 leaves only
after passing through a treatment device, which will usually be a
temporary sediment basin;
An un-disturbed, vegetation buffer zone and sediment fence barrier will
be maintained between the construction zone and any natural drainage
lines where possible;
Once the roadway stormwater swales are constructed, rock check
dams and other filters will provide pre-treatment for stormwater before
Ref: B12119ER002RevB-Draft EMP - 27 - Draft EMP – BORAL Gold Coast Quarry
flow enters the sediment basin;
Ensure construction vehicles exiting and entering Lot 105 are clean of
loose dirt or contaminants that may enter the roadway drainage system;
Minimize disturbance by construction worker’s vehicles via provision of
a stabilized parking area clear of earthworks areas;
Ensure progressive site stabilisation is implemented as soon as
practically possible, and maintained at all times during construction; and
Ensure that any temporary site buildings and permanent building roofs
are connected into the underground drainage system immediately
following roof gutter installation. No roofs shall discharge onto exposed
earthworks areas.
Monitoring Site Manager to ensure that run-off from all parts of the disturbed area
is directed into a sediment basin or through a silt fence before release
into natural environment.
Auditing Periodic inspection and reporting by professions qualified in sediment
and erosion control needs to be undertaken to ensure erosion and
sedimentation control measures are effective.
Reporting Any significant failures in erosion and sediment management are to be
recorded in Boral’s Incident Management System; and
A significant failure would include but not be limited to the following: a
structural failure of a sediment fence, sediment dam, formation of a
gully or overflow of sediment dams due to lack of capacity.
Corrective
Action
Any complaints related to water quality or any exceedences of approval
conditions for water quality at point(s) of discharge from site will trigger
an investigation into erosion and sediment control measures;
Action to improve the effectiveness of erosion and sediment control
measures will be taken were practical methods and technologies are
available.

5.5 NOISE
5.5.1 ELEMENT/ISSUE
The establishment, development and construction stages of the quarry involve the use of
mechanical equipment. Appropriate management measures need to be applied to ensure
compliance with required levels at noise sensitive areas and acceptable levels of amenity for
residences in the locality of the quarry. These measures are stated in the Construction Noise
Management Plan (CNMP).
When implemented, the mitigation measures will ensure that noise levels at sensitive receptors
do not exceed levels in the Environmental Protection (Noise) Policy or the levels described in the
AcousticsRB Baseline Report developed as part of the GCQ EIS.
5.5.2 MANAGEMENT PLAN
Operational Policy Objective – Noise
Ensure compliance with required levels at closest/most exposed sensitive receptors
Performance
Criteria
Regulatory noise limits are complied with when measured at sensitive
receptors (closest residences).
Implementation
Strategy
Workers and contractors shall be educated to maximise awareness of
project noise goals and unnecessary noise generating activities;
Activities that generate considerable noise shall be scheduled during
the least sensitive times of the day;
Construction processes and equipment shall be selected to minimise
the generation of noise;
Mobile mechanical equipment shall be fitted with effective exhaust
mufflers;
New technology reversing alarms shall be specified for all mobile plant;
Rock breaking, hammering, blasting and any other activities associated
with these stages of the quarry shall be carried out during the specified
daytime operational hours;
The strategic placement of items of major noise generating plant to
maximise the beneficial shielding provided by the retained high ground;
The construction of a 3m high noise barrier along the outer rim of the
sedimentation pond at Phase E3;
The construction and deployment of 5m high moveable modular
barriers close to the mobile primary crushers from the commencement
Ref: B12119ER002RevB-Draft EMP - 29 - Draft EMP – BORAL Gold Coast Quarry
of Establishment Phase E2/E3;
The deployment of a 5m high moveable modular barrier located in close
proximity to the mobile primary crusher throughout Phases C1 and C2;
and
Compliance with the requirements of the Construction Noise
Management Plan, especially with regard to the selection, operation
and maintenance of “low noise” plant and equipment.
Monitoring Refer Noise Monitoring Program – Section 9.3
Auditing The triennial environmental audit will review noise monitoring results
and adequacy of noise monitoring procedures.
Reporting Each noise monitoring report is to be submitted to the site manager for
review;
Noise monitoring results are to be presented as self-contained reports
which include a brief introduction including background on information
on complaints if any. Location and weather conditions and other factors
that may influence sound pressure levels are to be noted; and
All noise monitoring reports are to be retained for a period of not less
than 7 years.
Corrective
Action
Revise noise monitoring program so that it can meet relevant
standards, if a non-conformance with the monitoring program is
identified; and
Undertake a round of noise monitoring, after revision of noise
monitoring program and audit results.

5.6 BLAST VIBRATION
5.6.1 ELEMENT/ISSUES
Some blasting will take place during the establishment, development and construction phases,
including blasting for calibration of blasting models on local rock. Blasting is the only significant
source of vibration and produces both air-borne and ground-borne vibrations.
Overpressure
Air-borne vibrations, known as overpressure, include both audible and sub-audible (frequencies
less than 20 Hz) components. While the audible component of air-borne vibration from blasting
operations may be easily identified, the sub-audible component can manifest as shaking or
rattling of windows or objects on shelves inside a residential structure. While the sub-audible
component of overpressure is generally imperceptible outside a residence, it can be responsible
for secondary noises inside a residence (objects rattling).
In accordance with Australian regulations and standards, overpressure is measured as a peak
linear sound pressure level in decibels (dB(L)), though the levels should not be confused with A-
weighted noise levels (dBA).
Vibration
Ground-borne vibration radiates in all directions from the blast via the rock mass or soil, and is an
inevitable consequence of the blasting process. Due to attenuation and scattering, vibration
levels reduce with increasing distance from the source. In accordance with Australian regulations
and standards, vibration is measured as a peak particle velocity (mm/s).
5.6.2 MANAGEMENT PLAN
Operational Policy Objective – Blast Vibration
Blast vibration falls with regulatory limits at nearest sensitive receptors
Performance
Criteria
Airblast overpressure must not exceed 120dB (linear) peak for any
blast;
Ground-borne vibrations must not be more than 10mm/s for any blast;
and
Ground-borne vibrations must not be more than 5 mm/s for 9 out of 10
consecutive blasts and overpressure must not be more than 115 dB, for
9 out of any 10 consecutive blasts at a sensitive receptor.
Implementation
Strategy
Electronic initiation and single-hole firing will be used to ensure that no
two holes in any blast will fire at the same instant;
Blasting variables will be optimised to reduce the potential for vibration
Ref: B12119ER002RevB-Draft EMP - 31 - Draft EMP – BORAL Gold Coast Quarry
including:
- Blast hole diameter;
- Stemming;
- Charge weights; and
- Delay between firing adjacent charges.
More conservative blasting procedures may be used where blasting is
within 300m of private property.
Monitoring Refer Blast Monitoring Program – Section 9.2.
Auditing Triennial Environmental Audit and Monthly Environmental Checklist
Reporting Waveform diagrams and files from each blasting event will be submitted to SM
and REM. Non-conformances with blast limits will be reported as per non-
conformance reporting procedure in Boral’s Incident Management System.
Corrective
Action
Where vibration levels approach maximum permitted limits, the Drill & Blast
Contractor will be required to revise blast designs to ensure that vibration
levels do not exceed permitted limits.

5.7 AIR QUALITY
5.7.1 ELEMENT/ISSUE
Airborne dust may disperse beyond the site and may be deposited in residential areas. Dust can
come from disturbance of natural soils, from crushing of rock and particularly vehicle movements
over unsealed surfaces. Dust emissions can occur at any stage of the quarrying process
including:
Clearing;
Excavating;
Material handling (bulldozers / front end loaders / scrapers);
Crushing and screening by mobile plant;
Haulage of material (wheel generated dust);
Wind erosion of raw material and product stockpiles; and
Wind erosion of exposed areas.
Air quality also covers other potential pollutants such as vehicle exhausts, volatile/gaseous chemicals, smoke and odours. Modeling has demonstrated that emission rates are so low that
Ref: B12119ER002RevB-Draft EMP - 32 - Draft EMP – BORAL Gold Coast Quarry
the quarry will have a negligible impact on local air quality. These aspects are not considered further.
5.7.2 MANAGEMENT PLAN
Operational Policy Objective – Air Quality (Dust)
Airborne Dust shall be minimised as far as practicable during the Establishment and Development Stages of the quarry
Performance
Criteria
Dust deposition rates at sensitive receptors are lower than regulatory
limits and as low as reasonably possible within the disturbance area of
the quarry.
Implementation
Strategy
Cleared areas shall be stabilised as soon as practicable in order to
minimise the amount of exposed ground during the works;
Access to exposed areas shall be restricted in order to prevent
disturbance where practicable;
Stockpiled materials shall be placed within designated stockpile areas,
spread of stockpile material into adjacent areas shall be prevented;
Stockpile areas shall be watered on a regular basis and as required;
Vehicles operated within the site shall be restricted to designated
entry/exit points and internal roadways;
Vehicle speed shall be limited to appropriate speeds on all internal
roadways;
Trucks transporting material from the site shall have the load covered in
accordance with Boral’s tarping policy;
Truck underbodies and tyres shall be washed prior to leaving the site;
and
Internal roadways and trafficked areas shall be regularly watered.
Monitoring Refer Dust Monitoring Program – Section 9.4.
Auditing The triennial environmental audit will review dust monitoring results and
adequacy of dust monitoring procedures.
Reporting A report is to be submitted to the site manager within seven (7) days of
dust deposition rates being measured; and
Any exceedences of regulatory limits in dust deposition rates will be
drawn to the attention of the site manager, and required to be reported
as a non-conformance in the Boral Incident Management System
Ref: B12119ER002RevB-Draft EMP - 33 - Draft EMP – BORAL Gold Coast Quarry
Corrective
Action
Investigations into the source of the dust will be undertaken and
additional mitigation measures applied where practical.

5.8 VEGETATION AND FAUNA MANAGEMENT
5.8.1 ELEMENT/ISSUES
Aerial photographs taken in 1974 show that the project footprint had been almost completely
cleared of native vegetation to provide pasture for grazing. Small areas of remnant vegetation
associated with drainage lines were retained and the quarry has been configured to avoid these
areas as much as possible. Native forest regeneration has reclaimed much of the site, however
this forest vegetation is considerably less diverse and structurally less complex than the patches
of remnant vegetation. Clearing of the maturing regrowth vegetation is of lower environmental
consequence than the clearing of remnant vegetation however the forest regeneration outside the
disturbance footprint is of moderate quality for threatened species such as koalas and glossy
black cockatoos and the habitat values in the buffer area around the quarry are to be protected.
This section covers measures that have been put in place to manage impacts associated with the
clearing of vegetation.
5.8.2 MANAGEMENT PLAN
Operational Policy Objective – Vegetation and Fauna Management
Vegetation Clearing is undertaken in a way that minimises the area cleared, impacts to fauna from the clearing process and soil disturbance.
Performance
Criteria
Vegetation clearance shall be undertaken in a staged and controlled
manner to ensure minimal impacts of vegetation clearance and that
retained vegetation is not compromised by site clearing works.
Implementation
Strategy
Clearing of vegetation is undertaken according to Boral’s SOP;
No tree in which a koala is present, or a tree with a crown overlapping a
tree in which a koala is present, is to be cleared;
During the construction phases and for the life of operational activities
native vegetation clearing will be undertaken as sequential clearing and
under the guidance of a wildlife spotter;
Activities are staged in line with operational needs (i.e. no area clearing
will occur until the pending phase of the project requires clearing);
Ref: B12119ER002RevB-Draft EMP - 34 - Draft EMP – BORAL Gold Coast Quarry
Clearing will be undertaken sequentially, with clearing of vegetation that
ensures not more than three hectares or 3 per cent of the site’s area,
whichever is the greater; is cleared in any one stage; and
A break in clearing is to be undertaken between each stage, with such
breaks lasting at least 12 hours, generally from 6.00 pm to 6.00 am on
the following day.
Monitoring Monitoring of recently cleared areas should be undertaken to confirm
that the implementation strategy has been followed and that the
recently cleared areas have been placed in a state that minimised risk
to surrounding environment; and
Site Manager to ensure that safeguards are in place before any clearing
event takes place.
Auditing As vegetation clearing (and the stripping of overburden) is the most
significant impact of the quarry project on the natural environment,
external audits of the work will be undertaken at regular intervals.
External audits can include inspections by the REM or independent
consultants
Reporting Immediately report any incident which contravenes the objectives of the
EMP to the SM, REM and the appropriate regulatory body if required;
and
Any significant failure to follow the Boral SOP for clearing should be
recorded in the Incident Management System.
Corrective
Action
Investigate whether Boral SOP is being followed and take appropriate
action in cases where the SOP has not been followed.

5.9 CULTURAL HERITAGE
5.9.1 ELEMENT/ISSUES
Significant amounts of vegetation clearing and site disturbance will be undertaken during the
Establishment, Development and Construction Stages. Despite Cultural Heritage surveys having
been conducted and concluding that the site is unlikely to preserve any sites of scientific or
historical interest, there remains a possibility that items of potential cultural heritage significant
could be discovered during works.
Non-Indigenous Cultural Heritage
Settlement of the general area by Europeans commenced approximately 150 years ago with
logging, grazing and cropping being the main activities. In the latter half of the twentieth century,
primary industries declined and were replaced by urban land uses in the surrounding district.
Grazing continued on the site until 1995, however as the site was part of a larger property,
structures associated with that land use were not located on the present site. The non-
indigenous cultural heritage assessment report considers that there is a low likelihood of items of
archaeological significance being uncovered by the project.
As the recorded history of the site is not comprehensive, there is a possibility that unknown
activities took place on the site (including effected parts of Old Coach Road) and unknown but
historically valuable artifacts could potentially be discovered.
Indigenous Cultural Heritage
Indigenous cultural heritage (ICH) may also be present. Some stone artifacts, and stone chips
created during production of stone tools have been located on the site. The only site of potential
cultural heritage value is located outside the disturbance footprint for the quarry and has been
designated a restricted area until further investigations can be undertaken. Indigenous cultural
heritage is most likely to be located on ridge crests as steep slopes were not considered prime
places for indigenous activity and artifacts in or near creeks would have been washed away by
flooding.
On the basis of the findings of surface and sub-surface investigations, by Indigenous Cultural
Heritage Consultants (Jabree Limited), Boral have been advised that the proposed works
associated with the development area of the project known as the Gold Coast Quarry can
proceed without the need for further surveys.
5.9.2 MANAGEMENT PLAN
Operational Policy Objective – Cultural Heritage
Cultural heritage is protected from damage until clearances are provided.
Ref: B12119ER002RevB-Draft EMP - 36 - Draft EMP – BORAL Gold Coast Quarry
Performance
Criteria
Any discoveries of potentially important archaeological material are
assessed and managed in accordance with Cultural Heritage
Management Plans.
Implementation
Strategy
Non-indigenous cultural heritage will be protected by:
Provision of educational material to personnel informing them what
archaeological material may look like;
Stopping work with 20m of a potential archaeological find until an
assessment by an archaeologist can be made;
A requirement to notify the REM of the find and to engage a suitably
qualified professional to assess the find; and
A process for the collection, transport and storage of any archaeological
items.
Indigenous cultural heritage will be protected by:
Works to proceed in accordance with the Cultural Heritage
Management Plan and the Clearance Certificate (issued by Jabree
Limited and indicates which areas have already been cleared and can
be developed be developed without further surveys);
If during construction there is a significant and/or substantial find made,
works should cease and Jabree Limited should be contacted
immediately to advise and to negotiate further works by way of
mitigation;
Senior site workers undergo a 30 minute induction as provided for in
the Cultural Heritage Management Plan and commercial agreement
between Boral and Jabree Limited;
The site complex identified as B SC13 is located a considerable
distance from the disturbance footprint and is not at risk from quarry
operations. Site B SC13 must be designated as a works and access
exclusion zone at least until further investigations are undertaken and
results documented. The exclusion zone must extend 20m beyond the
boundaries; and
The SM is responsible for providing instructing quarry employees and
agents on which areas to avoid disturbing for Indigenous Cultural
Heritage reasons on an as necessary basis.
Monitoring All historical items uncovered should be immediately photographed,
described in words and located using a GPS. This description should
Ref: B12119ER002RevB-Draft EMP - 37 - Draft EMP – BORAL Gold Coast Quarry
be forwarded to the REM and recorded in Boral’s Incident Management
System; and
Prior to disturbing new areas, the site manager is to check that known
sites have been avoided and that any potentially significant finds have
been reported.
Auditing The relevant Archaeologist will provide management recommendations
to the Site Manager and will liaise with the DNRM to ensure that the
archaeological provisions of the Queensland Heritage Act 1992 are
followed.
Reporting Not required.
Corrective
Action
SM to undertake additional measures to prevent further works in areas
with known or suspected cultural heritage until advice from a suitably
qualified professional in cultural heritage has been received.

5.10 REHABILITATION
5.10.1 ELEMENT/ISSUES
Buffer zone restoration will occur outside of the footprint of the quarry during the Establishment,
Development and Construction Stage of the quarry. The main purpose of undertaking restoration
within the buffer zone is to support the Koala Management Plan, increase habitat for protected
species, enhance existing significant vegetation and rehabilitate the uncontrolled track network
created by unauthorized recreational vehicles with vegetation to reduce the sediment load coming
from these areas.
Ref: B12119ER002RevB-Draft EMP - 38 - Draft EMP – BORAL Gold Coast Quarry
5.10.2 MANAGEMENT PLAN
Operational Policy Objective – Rehabilitation
Existing disturbed areas in the buffer zone are rehabilitated
Performance
Criteria
Bushland buffer is to be managed in a way that maximises its
biodiversity and habitat values, particularly for koalas and glossy black
cockatoos;
Planted areas contribute to environmental offsets and provision of
additional feed trees for koalas and glossy black cockatoos; and
Groundcover vegetation and leaf litter is to be restored over unwanted
tracks to reduce erosion and sediment production.
Implementation
Strategy
In areas where planting is required, methods of site preparation, plant
selections and planting techniques in the Landscape Rehabilitation
Report are to be followed;
In the buffer zone, natural regeneration is to be the primary means of
rehabilitation;
Natural regeneration required protection from further impacts such as
vehicles and control of weeds that compete with native plants;
Areas that have been identified that require additional interventions
include:
- Riparian restoration. Three target areas on alluvial soils have
historically been cleared of trees and support variable, often
sparse, regeneration of native species along with abundant weeds;
- Fauna crossing at entry point. This area will require planting over
the batter and benches to facilitate fauna movement across the
proposed entry road;
- White-bellied sea-eagle buffer. The proposed setback provided to
the White-bellied sea-eagle limits views into the proposed pit and
plant site. It may however be necessary to enhance the screening
in the shrub and sub canopy layers through planting both uphill
and to the east of the nest tree;
- Former dam near quarry edge. This area of approximately 3,600m2
is located close to the quarry rim and is likely to be drained as part
of the quarry construction. If so, it is proposed that the area is
replanted with koala food trees; and
Ref: B12119ER002RevB-Draft EMP - 39 - Draft EMP – BORAL Gold Coast Quarry
- Vegetation Management Act 1999 Offset. Management of this area
will not differ from the surrounding vegetation. There is however an
expectation that there will be at least 1 weed treatment per year for
the first 3 years of management.
Monitoring Refer Ecological Monitoring Program – Section 9.6
Auditing Formal assessment of the effectiveness weed control and bush
regeneration is to be included in triennial independent environmental
audit.
Reporting Formal monitoring reports are to be provided to the SM and REM.
Corrective
Action
The SM is to be responsible for initiating further investigations into

required;
Additional surface cover is to be provided for areas where rehabilitation
has failed and ground surface is inadequately protected; and
Areas where rehabilitation has failed should be rehabilitated with a
different process or species selection which is selected for performance
under the conditions at the location where the rehabilitation failed.

5.11 CHEMICAL AND FUEL STORAGE
5.11.1 ELEMENT/ISSUES
On-site fuel storage will be required to provide for machinery used during the Establishment,
Development and Construction Phases. Permanent fuel storage tanks will be provided in the
Construction Stage. This element covers both temporary and permanent fuel storages.
Fuel and chemical storage on site creates a risk of leakage to the environment. As the drainage
system outside the operational area of the site will retain the natural drainage lines and riparian
vegetation, recovery of fuel and chemicals from this area would be costly, environmentally
damaging and may result in regulatory penalties.
Chemicals include other combustible substances, oxidising agents, corrosive agents and toxic
substances.
Ref: B12119ER002RevB-Draft EMP - 40 - Draft EMP – BORAL Gold Coast Quarry
5.11.2 MANAGEMENT PLAN
Operational Policy Objective – Chemical and Fuel Storage
To minimise the potential for fuel or chemical release into the environment
Performance
Criteria
All fuel and chemical storage facilities must comply with Australian
Standard AS 1940.
Implementation
Strategy
Site manager will be provided with a SOP for handling and storage of
hazardous materials;
Spill response procedures and equipment will be provided to reduce
risk of pollution in the event of a spill;
Bunds surrounding fuel storages shall be kept clean and dry and free of
presence of uncontained fuels that could provide ignition sources;
Bunds shall have an internal sump and/or valve with the valve being
locked shut except when releasing rainwater;
Accumulated rainwater will be released only if it is determined to be
clean by inspection or analysis for contaminants;
Visibly contaminated water is to be treated in a site surface water
interception system or treated by some other means to remove visible
oil;
Ensure that chemicals stored on site are below the maximum allowable
storage quantities; and
If multiple hazardous materials are stored, then the aggregate volume
should not exceed the maximum storage volume of the least hazardous
of these materials.
Monitoring Routine monitoring of tank and bund condition will be undertaken.
Auditing Periodic inspection of the storage facility by a qualified professional and
according to the monthly environmental checklist
Reporting Incidents will be reported using Boral’s Incident Management System.

5.12 WASTE MANAGEMENT
5.12.1 ELEMENT/ISSUES
A range of waste streams, including regulated wastes, will be generated through the life of the
project. Wastes generated during the Establishment, Development and Construction Phases are
likely to considerable and varied. Appropriate management of the handling, storage and disposal
of all waste streams is required.
A Waste Management Plan (Lambert & Rehbein 2013) (WMP) has been prepared which provides
detailed information on predicted waste streams and waste management requirements. A WMP
is required for dealing with regulated wastes such as tyres, batteries, paints and solvents. These
wastes are to be accounted for and removed to a suitably licenced disposal facility. Non -
regulated waste such as office waste that is not suitable for recycling can be removed from site
by a commercial waste contractor.
The information presented below shows the framework used by the WMP and is for information
purposes only.
5.12.2 MANAGEMENT PLAN
Operational Policy Objective – Waste
Sediment Generation Should Be Minimised And Sediment Contained Within Operational Areas
Performance
Criteria
All Regulated and Non-Regulated wastes to be handled and disposed
of in appropriate receptacles and to appropriate waste receiving
facilities; and
Wherever possible, waste generated on site shall be minimized and
reused/recycled.
Implementation
Strategy
Design to minimise production of waste from the Boral Gold Coast
Quarry facilities;
Minimise the generation of regulated waste;
Apply the waste management hierarchy of “avoid, reduce, recycle,
recover, treat and dispose”;
Apply sustainable waste management and disposal methods;
Avoid contamination of land and water;
Minimise adverse effects to aquatic and terrestrial vegetation and
wildlife; and
Minimise potential risks to workers and the public.
Monitoring The movement of regulated waste in Queensland is subject to a
Ref: B12119ER002RevB-Draft EMP - 42 - Draft EMP – BORAL Gold Coast Quarry
waste tracking system. The WMP includes the requirement for a
waste tracking system for regulated waste.
Auditing Formal review of waste management including the waste tracking
system is to be included in triennial environmental audit.
Reporting Waste generation, tracking, reuse and recycling data shall be
maintained for corporate reporting purposes.
Corrective
Action
On event of waste being disposed of incorrectly, the waste contractor or
site personnel shall be advised of the discretion and informed of the
correct practice. Waste to be recovered and returned to correct
handling and disposal approach.

6.0 ENVIRONMENTAL MANAGEMENT FOR OPERATIONAL
STAGE
6.1 BOUNDARY OF OPERATIONAL AREA
The quarry operation will take place on a Greenfield site bordering Old Coach Road and
Tallebudgera Creek Road.
The entire site covers 220 hectares (ha) and most of this area will remain as bushland and serve
as a buffer zone around the quarry. The area of disturbance including the access road,
operations area, pit and water storages will cover approximately 65 ha.
Significant buffer zones have been provided between the site boundary and any area of
disturbance.
6.2 OPERATING HOURS
During the Quarrying Phases Q1 to Q5, the proposed development will be operated within the
hours detailed in Table 4 below.
Table 4 Operating Hours for Quarry Operation Phase
Activity Hours of Operation
Access (general operations) 6:00am to 6:00pm Monday to Saturday
Extraction 7:00 am to 6:00pm Monday to Saturday
Sales and Dispatch 6:30am to 6:00pm Monday to Saturday
Crushing and Screening 7:00 am to 6:00pm Monday to Saturday
Maintenance 24 hours Monday to Saturday and
8:00am to 6:00pm Sundays
Blasting 9:00am to 5:00pm Monday to Friday
6.3 PLANT OUTPUT AND DURATION OF OPERATIONS
It is estimated that the upper production output from the plant will be in the order of 2 million
tonnes per annum throughout the operational life of the quarry, which will be in excess of 40
years. Full production is likely to be achieved 1-2 years after production commences, depending
on market conditions.
Ref: B12119ER002RevB-Draft EMP - 44 - Draft EMP – BORAL Gold Coast Quarry
6.4 NOISE
6.4.1 ELEMENT/ISSUES
Potentially sensitive noise receptors exist in the vicinity of the quarry site in current and future
residential areas. Without application of mitigation measures, noise levels could potentially
exceed regulatory limits or perceived nuisance levels at the receptor sites. However, when
mitigation measures are implemented, predicted noise emissions from the site will comply with
noise limits under all likely conditions.
Extensive and detailed noise modelling has been undertaken as part of the EIS process and the
conclusion is that compliance with the relevant noise level limits for the Quarrying Phases is fully
expected to be achieved provided noise control measures are fully implemented. For further
information refer to the EIS technical report “Assessment of Environmental Noise Issues for
Environmental Impact Statement” from AcousticsRB (2013).
6.4.2 MANAGEMENT PLAN
Operational Policy Objective – Noise
To protect the amenity of nearby residents from noise nuisance from activities associated
with quarry operations by ensuring the noise levels meet statutory requirements and
acceptable standards.
Performance
Criteria
Regulatory noise limits are complied with when measured at sensitive
receptors (closest residences).
Implementation
Strategy
The full enclosure of all fixed crushing and screening plant, with
openings let into the enclosures for the entry and passage of product
and conveyors only;
The construction of a 6m high 145m long fixed acoustic barrier which is
to be erected at RL 134-147 along part of the north-western boundary
of the disturbance area (Stage Q4);
Rock drilling to be carried out using a “low noise” rock drill only which is
to be operated for the minimum time feasible and, where necessary,
screened using moveable modular barriers located at appropriate
elevated positions between the operating drill rig and the nearest
residences;
Compliance with the requirements of the Environmental Noise
Management Plan, especially with regard to the selection, operation
and maintenance of “low noise” plant and equipment;
Ensure that noise emissions, both individually and cumulatively, do not
Ref: B12119ER002RevB-Draft EMP - 45 - Draft EMP – BORAL Gold Coast Quarry
adversely impact on local amenity;
Workers and contractors shall be informed of project noise goals and
noise mitigation measures;
Mobile plant is to be located in positions that maximise topographic
screening and distance from sensitive receptors where possible;
Mobile mechanical equipment shall be fitted with effective exhaust
mufflers;
Equipment with directional noise characteristics (emits noise strongly in
a particular direction) should be oriented such that noise is directed
away from sensitive areas; and
Boral vehicles and mobile plant will be fitted with new technology
reversing alarms.
Monitoring Refer Noise Monitoring Program – Section 9.3
Auditing Review of the site noise management practices should be carried out:
- At the start of quarrying activities; and
- Where upcoming quarrying activities indicate a high probability for
impact at sensitive receiver locations.
Reporting Routine noise monitoring reports shall be prepared and presented to
the SM.
Corrective
Action
Where monitoring shows unacceptable noise levels due to operational
activities, revision to the noise mitigation measures and management
activities shall be undertaken to ensure acceptable levels are achieved.

6.5 BLAST VIBRATION
6.5.1 ELEMENT/ISSUES
Blasting is the only significant source of vibration and comprises of air-borne and ground-borne
vibration.
Overpressure
Air-borne vibrations, known as overpressure, include both audible and sub-audible (frequencies
less than 20 Hz) components. While the audible component of air-borne vibration from blasting
Ref: B12119ER002RevB-Draft EMP - 46 - Draft EMP – BORAL Gold Coast Quarry
operations may be easily identified, the sub-audible component can manifest as shaking or
rattling of windows or objects on shelves inside a residential structure. While the sub-audible
component of overpressure is generally imperceptible outside a residence, it can be responsible
for secondary noises inside a residence (objects rattling).
In accordance with Australian regulations and standards, overpressure is measured as a peak
linear sound pressure level in decibels (dBL), though the levels should not be confused with A-
weighted noise levels (dBA).
Vibration
Ground-borne vibration radiates in all directions from the blast via the rock mass or soil, and is an
inevitable consequence of the blasting process. Due to attenuation and scattering, vibration
levels reduce with increasing distance from the source. In accordance with Australian regulations
and standards, vibration is measured as a peak particle velocity (mm/s).
6.5.2 MANAGEMENT PLAN
Operational Policy Objective – Blast Vibration
Blast vibration falls with regulatory limits at nearest sensitive receptors
Performance
Criteria
Airblast overpressure must not exceed 120dB (linear) peak for any
blast;
Ground-borne vibrations must not be more than 10mm/s for any blast;
and
Ground-borne vibrations must not be more than 5 mm/s for 9 out of 10
consecutive blasts and overpressure must not be more than 115 dB, for
9 out of any 10 consecutive blasts at a sensitive receptor.
Implementation
Strategy
Electronic initiation and single-hole firing will be used to ensure that no
two holes in any blast will fire at the same instant;
Blasting variables will be optimised to reduce the potential for vibration
including:
- Blast hole diameter;
- Stemming;
- Charge weights; and
- Delay between firing adjacent charges.
More conservative blasting procedures may be used where blasting is
within 300 m of private property.
Monitoring Refer Blast Monitoring Program – Section 9.2
Ref: B12119ER002RevB-Draft EMP - 47 - Draft EMP – BORAL Gold Coast Quarry
Auditing Triennial environmental audit and monthly environmental checklist
Reporting Waveform diagrams and files from each blasting event will be submitted
to SM and REM. Non-conformances with blast limits will be reported as per
non-conformance reporting procedure in Boral’s Incident Management
System.
Corrective
Action
Where vibration levels approach maximum permitted limits, the Drill & Blast
Contractor will be required to revise blast designs to ensure that vibration
levels do not exceed permitted limits.

6.6 AIR QUALITY
6.6.1 ELEMENT/ISSUES
Dust will be the primary air quality issue arising from the GCQ as a consequence of rock attrition
(crushing) which generates dust and earthmoving equipment which can remobilize surface dust.
Dust emissions can occur at any stage of the quarrying process including:
Material handling (bulldozers / front end loaders / scrapers);
Drilling;
Blasting;
Excavation;
Processing (crushing and screening) by both mobile and fixed plant;
Haulage of material (wheel generated dust);
Wind erosion of raw material and product stockpiles; and
Wind erosion of exposed areas (pit and plant).
The amount of dust emitted from the quarry will depend on the operations occurring at each stage
along with the management and mitigation measures that are employed to control dust.
Deposition of quarry dust in areas outside the quarry site represents a potential source of
nuisance. Dust containing very fine particles of silica is also known to have public health
implications and concentrations of airborne dust must be maintained below regulatory thresholds.
Modeling of dust from the proposed development and operation of the site suggest that
concentrations of respirable crystalline silica at the nearest sensitive areas to the quarry are likely
to be less that 10% of acceptable levels. The modeling was cumulative in that it included ambient
dust as well as project-related dust.
Ref: B12119ER002RevB-Draft EMP - 48 - Draft EMP – BORAL Gold Coast Quarry
Air quality also covers other potential pollutants such as vehicle exhausts, volatile/gaseous
chemicals, smoke and odours. Modeling has demonstrated that emission rates are so low that
the quarry will have a negligible impact on local air quality. These aspects are not considered
further.
6.6.2 MANAGEMENT PLAN
Operational Policy Objective – Air Quality (Dust)
Off-site dust dispersion levels comply with regulatory standards and development approval conditions.
Performance
Criteria
Dust deposition rates at sensitive receptors are lower than regulatory
limits and as low as reasonably possible within the quarry.
Implementation
Strategy
Use of water truck/s to wet down working roads and pads;
Water trucks to utilise polymer additives for efficient use of water, and
improved suppression where necessary;
Drill rig to have integral dust collector;
Install and use dust suppression systems on mobile crushing and
screening plant and equipment;
Use of foam dust suppression additives in dust suppression systems
where necessary;
Internal access road from intersection to car park will be sealed
(concrete / asphalt / bitumen sealed);
Fixed crushing and screening plant to have enclosures and dust
suppression systems (sprays fine mists of water over material transfer
points);
All external conveyors to/from fixed plant to be fitted with rain/wind
covers;
All product dispatch trucks will pass through wheel wash units and
loads will be covered using tarp truck bodies;
A street sweeper will be employed to periodically sweep the internal
roads and turnout areas to Old Coach Road;
Final product is to be stored in contained storage in "toast-rack"
bunkers; and
Stockpiles and product storage facilities to be sited and oriented to
reduce wind exposure where possible.
Ref: B12119ER002RevB-Draft EMP - 49 - Draft EMP – BORAL Gold Coast Quarry
Monitoring Boral will conduct routine monitoring of the exposure of its workforce to
respirable crystalline silica throughout the lifetime of the GCQ;
Refer Air Quality Monitoring Program – Section 9.4.
Auditing Monthly checks are to be made that meteorological data and dust
monitoring are taking place and data is being properly recorded; and
Checks of dust suppression measures are included in monthly
environmental checks.
Reporting Reporting will be undertaken and regular intervals according to
approval conditions;
A report is to be submitted to the site manager within seven (7) days of
dust deposition rates being measured; and
Any exceedences of regulatory limits in dust deposition rates will be
drawn to the attention of the SM.
Corrective
Action
Visible airborne dust emissions will be investigated and where possible
actions taken to reduce further emissions; and
Site manager is to be responsible for initiating further investigations into
dust or air quality related complaints and for implementing corrective
actions to reduce dust emissions.

6.7 STORMWATER MANAGEMENT
6.7.1 ELEMENT/ISSUES
Stormwater management is the key element in preventing sediment-related environmental
impacts both on and off site. The objective of stormwater management is to prevent sediment
entering natural drainage systems, where it can damage ecosystems or cause visible increases
in watercourse turbidity in the densely settled downstream catchment. Flooding issues have also
been investigated and potential changes to flood extent and velocity as a result of the project are
not considered to be significant and no specific mitigation is required.
A Stormwater Management Plan (SWMP, Lambert & Rehbein 2013) has also been prepared
which describes the location and sizing of drainage and sediment ponds within the operational
area. The information presented below is for information purposes only.
6.7.2 MANAGEMENT PLAN
Operational Policy Objective – Stormwater
Water-borne sediment from operational areas is to be captured and removed from waters released to the environment.
Performance
Criteria
Ensure neutral and/or beneficial changes to water quality in
downstream catchments;
Comply with environmental laws and project approval conditions; and
Maximise re-use of water and self-sufficiency.
Implementation
Strategy
Clean stormwater will be diverted away from the quarry disturbance
footprint;
A permanent sediment pond shall be constructed early in the
establishment phase so that runoff from the disturbed site can be
effectively treated before release to the downstream environment;
Runoff from within the quarry footprint will be directed into a sump in the
quarry pit or into the sediment pond;
Catch drains, stormwater diversion and other drainage infrastructure
shall be constructed to remain stable and meet relevant engineering
design criteria;
Access roads will be constructed with suitable scour protection and
drainage;
Water from the sediment pond will be re-used where possible for tasks
such as process water or dust suppression;
On-demand flocculation and relatively long residence times for
Ref: B12119ER002RevB-Draft EMP - 51 - Draft EMP – BORAL Gold Coast Quarry
stormwater entering the sediment pond will remove excess sediment;
Release of water into the natural drainage systems from the sediment
pond will only occur if the pond water meets water quality objectives or
during major events when stormwater volume exceeds dam or pond
capacity; and
Accumulated sediments will periodically be removed from the sediment
pond for disposal.
Monitoring Inspect sediment basins and drainage structures on a regular basis and
after heavy rain events or when using large quantities of water; and
Routine water quality monitoring is to be undertaken in sediment pond
according to approval conditions.
Auditing Performance of erosion and sediment control and water quality monitoring
data to be subject to triennial environmental audit and monthly environmental
checklist.
Reporting Immediately report any incident, spill or release of materials to the
environment to Project Supervisor and the SM, to be recorded in
Boral’s incident management system and managed appropriately; and
REM is also to be advised and water quality monitoring reports will identify
any breaches of water quality limits and a record will be entered into Boral’s
Incident Management System.
Corrective
Action
SM to investigate or arrange for investigation of reason for poor
discharge water quality monitoring results; and
Corrective actions to be taken as appropriate to restore discharge water
quality.

6.8 VEGETATION AND FAUNA MANAGEMENT
6.8.1 ELEMENT/ISSUES
Aerial photographs taken in 1974 show that the project footprint had been almost completely
cleared of native vegetation to provide pasture for grazing. Small areas of remnant vegetation
associated with drainage lines were retained and the quarry has been configured to avoid these
areas. Native forest regeneration has reclaimed much of the site, however this forest vegetation
is considerably less diverse and structurally less complex than the patches of remnant vegetation.
Clearing of the maturing regrowth vegetation is of lower environmental consequence than the
clearing of remnant vegetation however the forest regeneration outside the disturbance footprint
is of moderate quality for threatened species such as koalas and glossy black cockatoos and the
habitat values in the buffer area around the quarry are to be protected.
This section covers measures that have been put in place to manage impacts associated with the
clearing of vegetation.
6.8.2 MANAGEMENT PLAN
Operational Policy Objective – Vegetation and Fauna Management
Vegetation Clearing is undertaken in a way that minimises the area cleared, impacts to fauna from the clearing process and soil disturbance.
Performance
Criteria
Vegetation clearance shall be undertaken in a staged and controlled
manner to ensure minimal impacts of vegetation clearance and that
retained vegetation is not compromised by site clearing works.
Implementation
Strategy
Clearing of vegetation is undertaken according to Boral’s SOP;
No tree in which a koala is present, or a tree with a crown overlapping a
tree in which a koala is present, is to be cleared;
During construction phases and for the life of operational activities
native vegetation clearing will be undertaken as sequential clearing and
under the guidance of a wildlife spotter;
Activities are staged in line with operational needs (i.e. no area clearing
will occur until the pending phase of the project requires clearing);
Clearing will be undertaken sequentially, with clearing of vegetation that
ensures not more than three hectares or 3 per cent of the site’s area,
whichever is the greater; is cleared in any one stage; and
A break in clearing is to be undertaken between each stage, with such
breaks lasting at least 12 hours, generally from 6.00 pm to 6.00 am on
the following day.
Ref: B12119ER002RevB-Draft EMP - 53 - Draft EMP – BORAL Gold Coast Quarry
Monitoring Monitoring of recently cleared areas should be undertaken to confirm
that the implementation strategy has been followed and that the
recently cleared areas have been placed in a state that minimised risk
to surrounding environment;
Site Manager to ensure that safeguards are in place before any clearing
event takes place; and
Refer Ecological Monitoring Program – Section 9.6.
Auditing As vegetation clearing (and the stripping of overburden) is a significant
impact of the quarry project on the natural environment, external audits
of the work will be undertaken at regular intervals. External audits can
include inspections by the REM or independent consultants.
Reporting Immediately report any incident which contravenes the objectives of the
EMP to the SM, REM and the appropriate regulatory body if required;
and
Any significant failure to follow the Boral SOP for clearing should be
recorded in the Incident Management System.
Corrective
Action
Investigate whether Boral SOP is being followed and take appropriate
action in cases where the SOP has not been followed.

6.9 CULTURAL HERITAGE
6.9.1 ELEMENT/ISSUES
Non-Indigenous Cultural Heritage
Settlement of the general area by Europeans commenced approximately 150 years ago with
logging, grazing and cropping being the main activities. In the latter half of the twentieth century,
primary industries declined and were replaced by urban land uses in the surrounding district.
Grazing continued on the site until 1995, however as the site was part of a larger property,
structures associated with that land use were not located on the present site. The non-
indigenous cultural heritage assessment report considers that there is a low likelihood of items of
archaeological significance being uncovered by the project.
As the recorded history of the site is not comprehensive, there is a possibility that unknown
activities took place on the site (including effected parts of Old Coach Road) and unknown but
historically valuable artefacts could potentially be discovered.
Indigenous Cultural Heritage
Indigenous cultural heritage (ICH) may also be present. Some stone artifacts, and stone chips
created during production of stone tools have been located on the site. The only site of potential
cultural heritage value is located outside the disturbance footprint for the quarry and has been
designated a restricted area until further investigations can be undertaken. Indigenous Cultural
Heritage is most likely to be located on ridge crests as steep slopes were not considered prime
places for indigenous activity and artefacts in or near creeks would have been washed away by
flooding.
On the basis of the findings of surface and sub-surface investigations, by ICH Consultants
(Jabree Limited), Boral was advised that the proposed works associated with the development
area of the project could proceed without the need for further surveys.
6.9.2 MANAGEMENT PLAN
Operational Policy Objective – Cultural Heritage
Cultural heritage is protected from damage until clearances are provided.
Performance
Criteria
Any discoveries of potentially important archaeological material are
assessed and managed in accordance with Cultural Heritage
Management Plans; and
Areas with known archaeological material are not disturbed.
Implementation
Strategy
Non-indigenous cultural heritage will be protected by:
Provision of educational material to personnel informing them what
Ref: B12119ER002RevB-Draft EMP - 55 - Draft EMP – BORAL Gold Coast Quarry
archaeological material may look like;
Stopping work with 20m of a potential archaeological find until an
assessment by an archaeologist can be made;
A requirement to notify the REM of the find and to engage a suitably
qualified professional to assess the find; and
A process for the collection, transport and storage of any archaeological
items.
Indigenous cultural heritage will be protected by:
Works to proceed in accordance with the Cultural Heritage
Management Plan and the Clearance Certificate (issued by Jabree
Limited and indicates which areas have already been cleared and can
be developed be developed without further surveys);
If during construction there is a significant and/or substantial find made,
works should cease and Jabree Limited should be contacted
immediately to advise and to negotiate further works by way of
mitigation;
Senior site workers undergo a 30 minute induction as provided for in
the Cultural Heritage Management Plan and commercial agreement
between Boral and Jabree Limited;
The site complex identified as B SC13 is located a considerable
distance from the disturbance footprint and is not at risk from quarry
operations. Site B SC13 must be designated as a works and access
exclusion zone at least until further investigations are undertaken and
results documented. The exclusion zone must extend 20m beyond the
boundaries; and
The SM is responsible for providing instructing quarry employees and
agents on which areas to avoid disturbing for Indigenous Cultural
Heritage reasons on an as necessary basis.
Monitoring All historical items uncovered should be immediately photographed,
described in words and located using a GPS. This description should
be forwarded to the REM and recorded in Boral’s Incident Management
System; and
Prior to disturbing new areas, the site manager is to check that known
sites have been avoided and that any potentially significant finds have
been reported.
Ref: B12119ER002RevB-Draft EMP - 56 - Draft EMP – BORAL Gold Coast Quarry
Auditing The Historic Archaeologist will provide management recommendations
to the Site Manager and will liaise with the DEHP to ensure that the
archaeological provisions of the Queensland Heritage Act 1992 are
followed.
Reporting Not required.
Corrective
Action
SM to undertake additional measures to prevent further works in areas
with known or suspected Cultural Heritage until advice from a suitably
qualified professional in Indigenous or Non-Indigenous Cultural
Heritage has been received.

6.10 VISUAL IMPACT
6.10.1 ELEMENT/ISSUES
The EIS visual impact assessment indicates that after 25-30 years a small percentage of
residential locations will have limited views of up to 5-6 quarry benches in the most elevated parts
of the quarry pit will be visible to nearby residential areas. Visual impact mitigation centres on
restoring vegetation cover to visible quarry benches as soon as possible to allow establishment of
effective screening.
Other parts of the quarry pit and the plant and facilities area will be topographically screened and
will not need visual impact mitigation.
The information provided here is largely drawn from a technical report Visual Impact Assessment
for Gold Coast Quarry EIS (Cardno Chenoweth Report CEL 12001A).
6.10.2 MANAGEMENT PLAN
Operational Policy Objective – Visual Impacts
Visibility of the quarry pit or quarry infrastructure is to be minimised.
Performance
Criteria
Quarry pit, plant and infrastructure visibility from residential areas and
key public spaces is minimised; and
Identified interim and terminal bench faces which are visible from
residential areas and public spaces are revegetated as soon as
Ref: B12119ER002RevB-Draft EMP - 57 - Draft EMP – BORAL Gold Coast Quarry
practical after quarrying activity on these benches ceases.
Implementation
Strategy
Elevated quarry benches that will be visible from surrounding land are
to be progressively rehabilitated;
Fixed and mobile plant should be located where possible in locations
that are fully topographically screened;
Noise barriers should be provided with vegetative screening or be
directly camouflaged if they are visible from external locations;
Make use of temporary screening using fast growing temporary tree
plantings or man-made materials; and
Measures are taken to visually break up large flat bench faces that can
be seen from external locations.
Monitoring Regular informal revegetation monitoring to ensure plants are surviving
and are not being stressed by drought or other conditions;
Formal monitoring of rehabilitation works will be undertaken at least
twice during the 24 month maintenance period;
Informal monitoring from key external vantage points to ensure that
quarry benches visibility is being minimised. (See Visual Impact
Assessment Report by Cardno Chenoweth); and
Informal monitoring is to include a time series of digital photographs
taken with zoom lens of any visible benches is to be recorded so that
visual impact mitigation measures can be assessed.
Auditing Formal assessment of the effectiveness of visual screening is to be
included in triennial environmental audit.
Reporting Formal reporting to REM should be via the triennial environmental
audit.
Corrective
Action
Should informal assessment reveal that some quarry benches are
highly visible in most conditions or in particular lighting conditions, then
additional screening works should be undertaken to mitigate these
visual impacts.

6.11 REHABILITATION
6.11.1 ELEMENT/ISSUES
Rehabilitation activities have been separated into three components:
a) Buffer Zone Restoration activities - occur outside of the footprint of the quarry, are ongoing
over the life of the quarry, and as soon as the project works commence on site;
b) Quarry Zone Rehabilitation - the quarry and crushing plant construction and associated
activities and infrastructure - occur at the completion of various separable portions of the
quarry construction and in some cases are temporary; and
c) Quarry Zone Decommissioning - final terminal earthworks rehabilitation and stabilization.
This EMP covers only item a) and b) as these items will commence with the stages that are
covered by the EMP. With respect to item c), the quarry floor will be stabilized and rehabilitated
in accordance with an approach defined 5 years prior to decommissioning. Planning for these
aspects will take place at least 40 years in the future.
6.11.2 MANAGEMENT PLAN
Operational Policy Objective – Rehabilitation
Existing disturbed areas in the buffer zone are rehabilitated
Quarry benches which are available for permanent rehabilitation are rehabilitated
Performance
Criteria
Bushland buffer is to be managed in a way that maximises its
biodiversity and habitat values, particularly for koalas and glossy black
cockatoos;
Revegetation of exposed quarry benches is to occur as soon as
possible after the quarry bench has reached its interim or terminal
position and quarrying operations have ceased; and
Tree species that support koalas are to make up a high proportion of
species planted.
Implementation
Strategy
A detailed rehabilitation strategy is provided in the Landscape
Rehabilitation Report Gold Coast Quarry EIS technical report (Cardno-
Chenoweth document 12CEL001);
In areas where planting is required, methods of site preparation, plant
selections and planting techniques in the Landscape Rehabilitation
Report are to be followed;
In the buffer zone, natural regeneration is to be the primary means of
rehabilitation;
Natural regeneration required protection from further impacts such as
Ref: B12119ER002RevB-Draft EMP - 59 - Draft EMP – BORAL Gold Coast Quarry
vehicles and control of weeds that compete with native plants;
Areas that have been identified that require additional interventions
include:
Riparian restoration. Three target areas on alluvial soils have
historically been cleared of trees and support variable, often
sparse, regeneration of native species along with abundant
weeds;
Fauna crossing at entry point. This area will require planting over
the batter and benches to facilitate fauna movement across the
proposed entry road;
White-bellied sea-eagle buffer. The proposed setback provided
to the White-bellied sea-eagle limits views into the proposed pit
and plant site. It may however be necessary to enhance the
screening in the shrub and sub canopy layers through planting
both uphill and to the east of the nest tree;
Former dam near quarry edge. This area of approximately
3,600m2 is located close to the quarry rim and is likely to be
drained as part of the quarry construction. If so, it is proposed
that the area is replanted with koala food trees;
Vegetation Management Act 1999 Offset. Management of this
area will not differ from the surrounding vegetation. There is
however an expectation that there will be at least 1 weed
treatment per year for the first 3 years of management; and
Noise barrier screening. A proposed noise barrier is that is 6m
high and 150m long will be located parallel to and 6 m inside the
common boundary with Stage 20 of the Observatory Estate.
Monitoring Refer Ecological Monitoring Program – Section 9.6
Auditing Formal assessment of the effectiveness of visual screening is to be
included in triennial environmental audit.
Reporting Formal monitoring reports are to be provided to the SM and REM
Corrective
Action
The site manager is to be responsible for initiating further investigations
into rehabilitation-related issues and for implementing corrective actions
as required;
Additional surface cover is to be provided for areas where rehabilitation
has failed and ground surface is inadequately protected; and
Ref: B12119ER002RevB-Draft EMP - 60 - Draft EMP – BORAL Gold Coast Quarry
Areas where rehabilitation has failed should be rehabilitated with a
different process or species selection which is selected for performance
under the conditions at the location where the rehabilitation failed.

6.12 CHEMICAL AND FUEL STORAGE
6.12.1 ELEMENT/ISSUES
Fuel and chemical storage on site creates a risk of leakage to the environment. As the drainage
system outside the operational area of the site will retain the natural drainage lines and riparian
vegetation, recovery of fuel and chemicals from this area would be costly, environmentally
damaging and may result in regulatory penalties.
Chemicals include other combustible substances, oxidising agents, corrosive agents and toxic
substances.
6.12.2 MANAGEMENT PLAN
Operational Policy Objective – Chemical and Fuel Storage
To minimise the potential for fuel or chemical release into the environment
Performance
Criteria
All fuel and chemical storage facilities must comply with Australian
Standard AS 1940.
Implementation
Strategy
Site manager will be provided with a SOP for handling and storage of
hazardous materials;
Spill response procedures and equipment will be provided to reduce
risk of pollution in the event of a spill;
Bunds surrounding fuel storages shall be kept clean and dry and free of
presence of uncontained fuels that could provide ignition sources;
Bunds shall have an internal sump and/or valve with the valve being
locked shut except when releasing rainwater;
Accumulated rainwater will be released only if it is determined to be
clean by inspection or analysis for contaminants;
Visibly contaminated water is to be treated in a site surface water
Ref: B12119ER002RevB-Draft EMP - 61 - Draft EMP – BORAL Gold Coast Quarry
interception system or treated by some other means to remove visible
oil;
Ensure that chemicals stored on site are below the maximum allowable
storage quantities; and
If multiple hazardous materials are stored, then the aggregate volume
should not exceed the maximum storage volume of the least hazardous
of these materials.
Monitoring Routine monitoring of tank and bund condition will be undertaken.
Auditing Periodic inspection of the storage facility by a qualified professional and
according to monthly environmental checklist.
Reporting Incidents will be reported using Boral’s Incident Management System.
Corrective
Action
Should fuel or chemical leaks be observed or issues that could lead to
leaks be detected, these are to be reported to the Site Manager and to
the REM to organise corrective action.
6.13 WASTE MANAGEMENT
6.13.1 ELEMENT/ISSUES
A Waste Management Plan (Lambert & Rehbein 2013) (WMP) has been prepared which provides
detailed information on predicted waste streams and waste management requirements. A WMP
is required for dealing with regulated wastes such as tyres, batteries, paints and solvents. These
wastes are to be accounted for and removed to a suitably licenced disposal facility. Non -
regulated waste such as office waste that is not suitable for recycling can be removed from site
by a commercial waste contractor.
The information presented below shows the framework used by the WMP and is for information
purposes only.
6.13.2 MANAGEMENT PLAN
Operational Policy Objective – Waste
Sediment Generation Should Be Minimised And Sediment Contained Within Operational Areas
Performance
Criteria
All Regulated and Non-Regulated wastes to be handled and disposed
of in appropriate receptacles and to appropriate waste receiving
facilities; and
Wherever possible, waste generated on site shall be minimized and
Ref: B12119ER002RevB-Draft EMP - 62 - Draft EMP – BORAL Gold Coast Quarry
reused/recycled.
Implementation
Strategy
Design to minimise production of waste from the Boral Gold Coast
Quarry facilities;
Minimise the generation of regulated waste;
Apply the waste management hierarchy of “avoid, reduce, recycle,
recover, treat and dispose”;
Apply sustainable waste management and disposal methods;
Avoid contamination of land and water;
Minimise adverse effects to aquatic and terrestrial vegetation and
wildlife; and
Minimise potential risks to workers and the public.
Monitoring The movement of regulated waste in Queensland is subject to a
waste tracking system. The WMP includes the requirement for a
waste tracking system for regulated waste.
Auditing Formal review of waste management including the waste tracking
system is to be included in triennial environmental audit.
Reporting Waste generation, tracking, reuse and recycling data shall be
maintained for corporate reporting purposes.
Corrective
Action
On event of waste being disposed of incorrectly, the waste contractor or
site personnel shall be advised of the discretion and informed of the
correct practice. Waste to be recovered and returned to correct
handling and disposal approach.

7.0 EMERGENCY AND HAZARDS MANAGEMENT
7.1 EXTREME RAINFALL AND FLOODING
7.1.1 ELEMENT/ISSUES
Extreme rainfall events could result in quarry-affected water being discharged into the drainage
system downstream of the operational site as the sediment pond and quarry dam fill to design
capacity and overflow.
Stability of fill embankments and topsoil dumps could also potentially be reduced.
Flooding on the site is confined to creeks and narrow valley bottoms, which are stabilised with
riparian vegetation. Flood modelling for the Flooding and Water Resources Report (BMT WBM
2012) show that flood volumes and flood extents downstream of the disturbance area will remain
similar to those experienced by the pre-quarry environment. The quarry plant and facilities are
located on high ground which is not flood prone.
7.1.2 MANAGEMENT PLAN
Operational Policy Objective – Extreme Rainfall and Flooding
Extreme rainfall events do not result in significant erosion of the site or sedimentation of waterways
Performance
Criteria
Erosion gullies do not develop in or below disturbed areas; and
Waters discharged from sediment dam and quarry dam come from the
clearest part of the waterbody.
Implementation
Strategy
Adjust quarry operations to minimise the generation of sediment during
periods when sediment control systems are not able to fully treat
stormwater before discharge from site;
Avoid working with materials that release large amounts of sediment
when wet such as topsoil;
Ensure vehicles are not used on unsealed tracks on the balance of the
site or on recently cleared areas when they are in a very wet condition;
Ensure stormwater drainage system and sediment pond systems are
functioning and are not subject to blockages or other failures;
Check areas undergoing revegetation as these areas are potentially
erosion prone until vegetation cover is established; and
If significant and uncontrolled movement of sediment is observed,
install temporary measures to contain sediment as necessary including
Ref: B12119ER002RevB-Draft EMP - 64 - Draft EMP – BORAL Gold Coast Quarry
simple measures such as silt socks, sand bags or silt fences.
Monitoring Inspect erosion prone surfaces for rills, track damage or damage to
erosion control structures after each rainfall event that delivers more
than 50 mm in 24 hours. Areas that need to be inspected include:
Topsoil stockpile;
Firebreak tracks, security fence tracks and
abandoned/rehabilitated off-road vehicle tracks; and
Spillways on quarry dam and sediment pond.
Where erosion or other issues has been observed it is to be
documented with photographs.
Auditing Review site records to ensure that inspections are taking place after
extreme rainfall events.
Reporting Reporting is to include any erosion or ground movement that has
occurred due to the rainfall event; and
Any areas in the buffer zone which are releasing large amounts of
sediment into drainage lines are to be reported to the site manager and
REM.
Corrective
Action
If undesirable outcomes have occurred, update SOP to include
additional provisions for managing erosion and sedimentation as a
result of extreme rainfall.

7.2 BUSHFIRE
7.2.1 ELEMENT/ISSUES
The terrain and vegetation present on the site create a significant bushfire hazard that must be
managed to reduce the potential for excessive environmental harm and property damage both on
and off-site.
Consultation with Stockland was undertaken in relation to The Observatory development,
specifically to enable integration of the Bushfire Risk Assessment and Mitigation Plan for The
Observatory with the GCQ BMP where necessary.
A Bushfire Management Plan has been prepared by Cardno-Chenoweth as part of quarry’s EIS.
The information below restates the key points of that plan.
7.2.2 MANAGEMENT PLAN
Operational Policy Objective – Bushfire
Bushfire hazard should not significantly increase as a result of the project
Performance
Criteria
Potential bushfire risks at the subject site and surrounds are identified;
Appropriate risk treatment options have been selected based on
analysis/evaluation of risks; and
Treatment options are prioritized in order to mitigate the bushfire risk
and its effects on life, property and the environment.
Implementation
Strategy
Plan, create and/or maintain strategic fire trails in order to implement
hazard reduction works;
Where possible, place gates on fire trails to prevent unauthorised
access;
Preferable burn season is summer to winter and aim for a low to
moderate intensity burn;
Exclude fire from environmental sensitive areas including riparian zones
and rainforest vegetation with particular attention to threatened species
that inhabit these communities (Syzygium moorei, Taeniophyllum
muelleri); and
Incorporate strategies to protect White Bellied Sea-eagle nest site
during their breeding season.
Monitoring Monitor the subject site, conditions and situation annually in order to
evaluate changes occurring on or off site, e.g. changes in infrastructure,
risks and hazards, legislative and environmental changes; and
Ref: B12119ER002RevB-Draft EMP - 66 - Draft EMP – BORAL Gold Coast Quarry
Auditing Confirm that tracks are to have a minimum cleared width, are to be
well-formed with appropriate slope and gradient, and have erosion
control devises compliant with GCCC standards
Reporting Unplanned bushfires are to be recorded on the Boral Incident
Management System.
Corrective
Action
Update the Bushfire Management Plan at 5 yearly intervals or earlier
dependent upon site conditions, legislative and environmental changes
as required.

replaced as necessary; and
Protective clothing shall be regularly inspected and maintained;
Absorbent materials shall be kept dry.
Ref: B12119ER002RevB-Draft EMP - 67 - Draft EMP – BORAL Gold Coast Quarry
In the event of a spill the procedure is to:
Refer to the onsite emergency response flowchart which will
detail immediate actions and lead to the correct management
and clean-up of the spill; and
The Material Safety Data Sheet (MSDS) shall be referred to in
order to identify the risk and management requirements of the
spill.
Monitoring The site manager shall ensure that:
MSDS are available via Chem Alert (Boral Intranet) for each
hazardous material handled on site;
The necessary Spill Station equipment and clean-up materials
are both available and maintained; and
All site personnel are trained to handle hazardous material spills
as per this procedure.
Auditing A review of spill responses and corrective actions is to be undertaken
as part of the triennial environmental audit of the quarry.
Reporting Each significant spill, defined as spills that required the use of a spill
station or special arrangement for the removal of contaminated
materials from site will be entered into Boral’s Incident Management
System. The register will record the date of the spill, the material and
quantity of material involved, actions taken and nature of final disposal
of contaminated waste;
Notify REM of spill; and
For significant spills, the government regulator will be contacted as
soon as possible, generally within 24 hours of the incident.
Corrective
Action
With assistance from the REM and site manager, determine the
ultimate cause of the spill and take appropriate action to reduce risk of
further spills in similar circumstances; and
Actions taken shall be formally documented and transmitted to all
relevant parties and SOP will be updated if necessary.

10.0 AUDITING AND REPORTING
10.1 AUDITING
Internal compliance auditing is to be undertaken in accordance with Boral SOPs which require
auditing by an Environmental Practitioner every 3 years, the triennial environmental audit. The
purpose of these audits is to identify non-compliances with approval conditions and management
system deficiencies to enable the development of corrective action plans.
External auditing also should be undertaken once every three years by a suitably qualified
independent consultant. The performance of the quarry or on-site construction projects should be
assessed against the policies, performance criteria and implementation strategies outlined in the
EMP that represented the finalised version of this draft EMP.
10.2 REPORTING
Internal reports are to be held with Boral’s corporate document management system for a period
of at least seven years. In some circumstances, documents may need to be retained for longer
periods.
Reports prepared by external consultants for public release should be presented in a format that
is suitable for presentation to the public. Results should be interpreted so that the significance of
any exceedences or incidents is put in terms that well-educated community members can easily
understand.
