1.0 INTRODUCTION
1.1 BACKGROUND
AustralAsian Resource Consultants (AARC) was commissioned by Taroom Coal Pty Ltd (the
Proponent) to undertake a Visual Amenity Assessment for the Elimatta Project (the Project). The
Project involves mining and beneficiation of coal and transport of product coal to link to the Surat
Basin Rail line. The open-cut mine plan is based on excavator and truck operation.
A Mining Lease Application (MLA 50254) has previously been submitted concurrently with an
application for an Environmental Authority (EA) for the proposed mining area, Exploration Permit for
Coal (EPC) 650. Linked via a transport corridor, the coal handling and processing plant (CHPP) and
related infrastructure would be located within another mining lease (MLA 50270) made over EPC
1171.
An amendment to the EA has been submitted to accompany additional MLAs required for the
proposed development of mining and processing infrastructure including connecting transport
corridors.
The Project also includes a 36 km Rail and Services Corridor connecting the Project site to the
proposed Surat Basin Rail line north of Wandoan.
1.2 PROJECT LOCATION
The Project is located within the Surat Energy Resources Province and the Surat Basin geological
region. The Project site is located approximately 35 kilometres (km) west of the Wandoan township in
the Darling Downs region, and 380 km north-west of Brisbane as shown in Figure 1. The Project is
located entirely within the Western Downs Regional Council area.
Access to the Project site is via Perretts Road (also known as the Yuleba Taroom Road) west of the
Leichhardt Highway. The proposed Mining Leases (ML) for both mine operations and transport will
cover an area of approximately 4460 hectares (ha).

2.0 PROJECT DESCRIPTION
The Project is based on the development of a thermal coal resource of more than 250 Million tonnes
(Mt) in the Surat Basin coal province in Queensland, Australia.
The Project area currently consists of 3 existing MLAs and a 36 km long Rail and Services Corridor.
MLA 50254 occurs where the open-cut pit is proposed, MLA50270 will consist of the CHPP and other
associated mine infrastructure including tailings storages and accommodation village, and MLA50271
will be the transportation corridor for transportation of Run-of-Mine coal from the pit to the CHPP. The
Project MLA boundary is approximately 4460 ha and is illustrated by Figure 2.
2.1 MINING OPERATIONS
The Project is planned to mine up to 8 Mt of Run-Of-Mine (ROM) coal per annum (pa) to produce on
average 5 Mt/pa of product coal for export. The open-cut mine plan is based on excavator and truck
operation feeding 1,100 tonnes per hour (tph), two-stage coal processing plant. Topsoil stripped prior
to mining will be segregated for later use in rehabilitation, with some overburden disposed of within
both in-pit, and out-of-pit spoils dumps located on site and contiguous with the pit excavation.
Processing will involve crushing, screening and washing to separate coal from waste materials. Waste
rejects will be dried, with water recycled to the processing plant and solids disposed of within spoil
dumps.
The construction period is anticipated to take approximately 22 – 24 months with operations
employees on site after 13 months. Initially the construction will involve earthworks in order to create a
landscape suitable for infrastructure development. Following the preliminary clearing of the site,
earthmoving equipment will remain in order to excavate areas for stage one of the open cut pit, the
spoil dumps, the Tailings Storage Facility (TSF), initial clearing of the Mine Infrastructure Area (MIA),
and internal transport corridors. Following initial construction appropriate machinery will be utilised to
construct remaining infrastructure including water infrastructure, CHPP, TSF, accommodation, roads,
the rail corridor, and other associated requirements.
Product coal is to be transported via a constructed rail-line termed the West Surat Link of
approximately 36 km to join the Surat Basin Rail to the north east of the Wandoan Township. Product
coal will be railed to the planned Wiggins Island Coal Terminal at Gladstone for export.
Based on a current assessment of the available resource, the predicted life on the mine is in excess of
25 years and is more likely to be around 32 years. Upon decommissioning of the mine the entire
Project site will be rehabilitated in accordance with best practices in consultation with relevant
government authorities and the post mining land owners.
Major elements of the Project include:
Open cut mining of the Elimatta coal resource, located within the MLA 50254;
Mining via continuous mining units which feed a mobile conveyor system for transfer of waste
and ore;
Transportation of ROM coal from MLA 50254 to the CHPP located, north, on MLA50270;
Processing of coal at the Elimatta CHPP, including crushing, screening and washing, with
waste products disposed of to a TSF and in later years, the mined out pits;
Visual Amenity Assessment 5 November 2012
Out-of-pit spoil dumps and in-pit spoil disposal at the Elimatta open-cut pit site (MLA 50254);
Rail loading and transport of processed coal via the West Surat Link of approximately 36 km
to join the Surat Basin Rail to the north east of Wandoan township; and
The diversion of Perretts Road.
The main visual elements of the Project are the following:
Open cut pit;
Surface infrastructure and facilities to service the open cut pit;
MIA;
Mine administration area;
Access and haul roads;
Spoil dumps;
CHPP;
TSF;
Surface and raw water storage dams;
Power and water supply infrastructure;
Train loading facility;
Rail alignment;
Diversion of Horse creek; and
Diversion of Perretts Road.
2.2 ROADS
The current Project site access is from Perretts Road. Perretts Road runs parallel to Horse Creek in a
north-south direction through the proposed Project site. As such, Perretts Road will need diverting in
order to accommodate the Project.
Perretts Road will be moved to the east of its current position and will remain as the primary access
road to the Project. Other roads, including Ryals Road, Cattle Downs Road, and Goldens Road will be
upgraded and/or relocated to further accommodate access to the Project site.
Specifically, as part of the Project, permanent road closures and realignments will be required to allow
construction of the Project. Constructed roads already in place and managed by the Western Downs
Regional Council will be upgraded to allow sufficient and efficient public access around the Project.
Roads which are directly affected by the Project are highlighted in Figure 3 and listed below:
Visual Amenity Assessment 6 November 2012
Perretts Road which runs through the middle of the mine area is to be relocated to the east
and connect south, to the Bundi Highway;
Part of Ryals Road across Horse Creek to Perretts Road. Also part of Perretts Road in the
vicinity of the Project infrastructure area is to be upgraded; and
Cattle Downs Road is upgraded to provide access to the Accommodation Village.
A new road is to be built to connect Cattle Downs Road with Goldens Road to maintain west side
access along Goldens Road which is closed because of the main mine haul road.

2.3 DESCRIPTION OF EXISTING LANDSCAPE
The region is generally undulating, formed on the argillaceous sediments of the Great Artesian Basin
(Sattler and Williams 1999). Low intensity cattle grazing and cropping are the dominant land uses
surrounding the Project site. Associated infrastructure on the site includes cattle yards, windmills,
dams and water storage tanks. There is also a disused cattle dip within the proposed mining area
(MLA 50254).
The topography of the site is generally flat with gentle hills, with elevations ranging from approximately
250 m to 300 m above sea level. Facing south-west towards the Project site, north of MLA 50270, are
small rolling hills which may effectively block views into the site from surrounding tenements. There
are no distinctive viewpoints surrounding the Project site.
Although the majority of vegetation is sparse due to historic land uses, buffers do exist and surround
various extents of the Project site. Predominately, topography and vegetation provide the greatest
buffers east and south of the Project site (benefiting those looking west onto the Project site), where
the majority of residencies are located. Details of photo site locations are provided in Figure 4, with
locations illustrated by Photo Plates 1 through to 18.

Horse Creek, a tributary of the Dawson River, meanders through the Project site from south to north
and is the most significant watercourse in the vicinity of the Project. Horse Creek passes centrally
through MLA 50254 and to the east of MLA 50270. The diversion of Horse Creek, within the confines
of the ML, will take place in 4 stages over 10 years.
The flow of ephemeral waterways within and surrounding the Project Site is restricted to heavy rainfall
events, which typically occur between November and February. Due to their ephemeral nature, the
use of watercourses within the vicinity of the Project is generally limited to stock watering, when water
is available, and are generally unsuitable for recreational use. Riverine / aquatic ecosystems have no
associated receivers (recreational users) and will not be included as a Visual Management Unit (VMU)
for this report.
Although areas in proximity to the West Surat Link are not heavily vegetated, scattered trees and
occasional slopes offer buffering consistent with the level of disturbance that may be experienced
within this region.
The following photos detail the visual amenity associated with the Rail and Services Corridor:

2.4 PROGRESSIVE REHABILITATION
The rehabilitation strategy for the Project focuses on rehabilitating all areas significantly disturbed by
surface mining activities to a stable landform with a self-sustaining vegetation cover. In order to reduce
the amount of disturbed land at any one time, rehabilitation will be progressively undertaken on areas
that cease to be used for mining or mining-related activities. Results from successful progressive
rehabilitation will be used to refine the proposed rehabilitation methods including aspects such as the
selection of appropriate drainage measures/structures and plant species for re-establishment.
Prior to mining, the Project site was used for low intensity grazing. No areas within the Project site
were suitable for forage or cash cropping uses. Rehabilitation of the Project area will return a stable
landform capable of land uses similar to those prior to disturbance with a similar appearance and
visual amenity values.
To achieve this, the nominated post-mine land use mosaic will link remnant native vegetation, where
practical, and will aim to return some of the existing conservation values.
All infrastructures will be removed, unless formal written agreements have been reached with the post-
mining landowners/managers for its ongoing use, and areas will be returned to the pre-mining
landuse.
Rehabilitation of disturbed land at the Project will be conducted so that:
Visual Amenity Assessment 18 November 2012
suitable species of vegetation are planted and established to achieve the nominated post-
mine land uses;
the potential for water and wind induced erosion is minimised, including likelihood of
environmental impacts being caused by the release of dust;
the quality of any surface water and seepage released from the Project is such that they are
not likely to cause environmental harm;
the water quality of any residual water bodies meets criteria for subsequent uses and does not
have the potential to cause environmental harm; and
the final landform is stable and not subject to slumping or erosion that would result in the
agreed post-mining landform not being achieved.
This rehabilitation strategy will return the land to a condition that has similar or identical visual amenity
values to the current land condition. By utilising these methods any major disturbances will be limited
to set timeframes.
2.5 SENSITIVE RECEIVERS
The location and proximity of receivers associated with the Project is shown in Figure 5 and
summarised in Table 1.
It should be noted that when a distance has been provided it has been measured to the Project
boundary and that the distance to actual disturbance will be further.

3.0 METHODOLOGY
3.1 OBJECTIVES OF THE VISUAL AMENITY ASSESSMENT
The objectives of the visual amenity assessment are to describe the existing landscape features,
panoramas and views that have or could be expected to have potential value to the community
whether of local, regional, State-wide, national or international significance. Information will be
provided in the form of maps, sections, elevations and photographs to address the following key
issues:
Potential impacts on major views, view sheds, existing viewing outlooks, ridgelines and
other features contributing to the amenity of the area, as well as private residences in the
potentially affected area along the route;
Identification of focal points, landmarks (built form or topography), gateways associated
with the Project site and immediate surrounding areas, waterways and other features
contributing to the visual quality of the area and the Project site and potential impacts that
may arise from the Project;
Assess the existing characteristics of the local and surrounding areas including character
of built form (scale, form, materials and colours) and vegetation (natural and cultural
vegetation) directional signage and land use and potential impacts that may arise from the
Project;
Identification of the areas of the proposal that have the capacity to absorb land use
changes without detriment to the existing visual quality and landscape character; and
Assess the value of existing vegetation as a visual screen.
3.2 ASSESSMENT PROCESS
The assessment of visual amenity values, or defining the impact of visual change, is typically a
subjective process. Each individual will generally place a different perception of the value of a view or
landscape. Generally, the higher the proportion of human-made features, the less appealing the view.
Variation in vegetation type also provides a significant visual influence. The more diverse or ‘green’
the landscape, the more visually appealing it usually becomes.
Visual values will be assessed and presented in terms of the extent (magnitude) and significance of
the changed skyline as perceived from places of residence, work and recreation, from transport
routes, from the air and other known vantage points day and night, during all stages of the project as it
relates to the surrounding landscape.
To reduce the level of subjectivity involved with this type of assessment, the visual impacts of
structures and associated infrastructure from the Project will be addressed using visual simulation
methods, maps, sections, elevations and photographs. Special consideration has been given to public
roads, public thoroughfares and places of residence or work, which are within the line-of-sight of the
Project.
Visual impacts relate to the quality of what people see from places they frequent. Landscape impacts
relate to the landscapes ability or lack thereof to accommodate change associated with the Project.
Landscape and visual impact may potentially result from the following:
Visual Amenity Assessment 22 November 2012
a) Construction of the proposed mine infrastructure, including effects such as lighting or fugitive
dust; and
b) Operation of the mine, including permanent loss of existing landscape features, permanent
structures, visible emissions and lighting.
Taking these factors into consideration, the following was undertaken to assess the potential impacts
of the proposed Project on visual amenity:
a) Field investigations to inspect the visual values of the Project site;
b) Panoramic and line-of-sight photographs taken from key vantage points surrounding the MLA
showing the existing landforms, vegetation and topography;
c) A review of the proposed mine stage plans and layout;
d) Review of topographical maps and aerial photographs; and
e) Analysis using appropriate simulation including diagrams, computer imaging, aerial
photographs, GIS and photos on near views and far views.
This assessment has been designed to help to quantify and summarise visual amenity values for the
Project and investigate any potential impacts associated with the Project. The design of the
assessment was heavily influenced by the Hong Kong Environmental Protection Department’s
Guidance Notes (GN 8/2010) on the Preparation of Landscape and Visual Impact Assessment Under
the Environmental Impact Assessment Ordinance (EPD 2010).
3.3 VISUAL MANAGEMENT UNITS FOR THE PROJECT
The Elimatta Project site is expansive and incorporates a variety of different landscapes and values.
To provide a more precise assessment of the visual amenity values associated with the Project site,
Visual Management Units (VMUs) have been developed for this visual amenity assessment. VMUs
have been created by grouping landscapes with the same broad characteristics (vegetation, land use
etc.) found on the Project site. Utilising VMUs will allow the site to be broken down and analysed at a
more manageable and accurate scale and outcomes will be more detailed.
Landscapes with distinctive landscape characteristics will be categorised into VMUs to assess the
potential impacts on the surrounding landscape and to determine the ability of certain landscapes to
absorb impacts associated with the Project. Landscape VMUs differ with diversity of the range of
features and patterns present, and consequently in their ability to accommodate different types of
development. Some areas may be particularly sensitive to development and others more resilient.
Landscape sensitivity will have a bearing on the overall level of significance of the impact on visual
amenity values. The magnitude of change and sensitivity assessment criteria for key landscapes
associated with the Project can be found in Table 4.
Sensitive receivers will also be categorised into VMUs to determine how significant potential impacts
on particular groups of receivers are likely to be. This will involve determining the receiver’s location
and the duration of exposure to a disturbance associated with the Project. A crucial aspect of
assessing VMUs sensitivity is their distance to disturbances. For this Project the defined distance
levels have been determined by assessing the topography. The level of sensitivity and magnitude of
change will be determined to assess the overall level of significance of potential impacts.
Visual Amenity Assessment 23 November 2012
Landscape VMUs are essentially what a receiver is looking at and Receiver VMUs are essentially how
many people are viewing a landscape, their distance to it and how long they view it for. The
Landscape VMUs for this site are presented in Table 2. The Receiver VMUs are presented in Table 3.

Visual Amenity Assessment 24 November 2012
These VMUs will be assessed against criteria set out in the following sections so that the overall level
of significance can be determined.
Location specific assessment involved taking photographs (panoramas and line-of-sight) from key
vantage points around the site. Certain sites were selected for more detailed analysis which involved
wide angled panoramic photographs with computer generated animations of proposed mine
components to show potential views of the Project. Other supplementary sites have also been
selected to provide north, east, south, west views or photos of areas of interest from sites surrounding
the Project.
3.4 PHOTOGRAPHIC LOCATION POINTS
All visual assessment sites (photo sites) are shown in Figure 6. These are sites where detailed line of
sight analysis was conducted and standard photographs and panoramic photographs were taken.

3.5 DEFINING OVERALL LEVEL OF SIGNIFICANCE
The Level of Significance will be determined for each VMU, which will provide an indicator as to how
significant the potential impacts from disturbances could be. This will assess disturbances according
to their severity as having potentially substantial, moderate, slight, or no significant impact on
associated receivers or landscapes. The severity or significance of an impact depends on both the
extent of change (a function of the nature, scale and visibility of the mine) and the sensitivity of the
landscape or observer to the change.
The more severe value will be used when a VMU falls between two classes.
The assessment process will follow the structure set out in Figure 7.

The criteria for defining the Level of significance for visual impacts are outlined in Table 6 below. The
overall level of significance is a combination of the number of receivers potentially affected, the
Visual Amenity Assessment 28 November 2012
distance of receivers to a disturbance and magnitude or extent of change. Levels of significance are
used throughout this document to standardise results of the assessment.

This method of assigning the level of significance of an impact takes into account the number of
viewers affected, the magnitude or extent of landscape change and the sensitivity of receivers and
landscapes. If many viewers will be affected the level of significance for that location would be higher
than if few viewers were affected. The same applies to landscape; where the scale of change is higher
the impact will be more significant. Landscape and receivers can be assessed and compared in a
more subjective way using this assessment method.
Visual Amenity Assessment 29 November 2012
The potential impacts and the level of significance for visual amenity values and landscape values will
be discussed in Section 6.0.
Visual Amenity Assessment 30 November 2012
4.0 MAJOR MINE COMPONENTS
4.1 MINE COMPONENTS
The potential impacts from various mine components can vary dramatically. The key factors in terms
of visual amenity values at this site will be vertical profile and magnitude or extent of change from
associated disturbances.
Major components of the Project will be described to determine the specific potential impacts
associated with each component. Many of these major elements will vary throughout the life of the
mine as will the associated impacts (see mine staging Section 4.3). Spoil dumps will be at their
greatest extent at the end of mine life, but will also be progressively rehabilitated, which will help to
reduce the potential effects. Certain mine components may also block existing or future mine
components from causing an impact. One example would be a spoil dump blocking the MIA from view
from certain locations.
Mining Areas, Final Voids and Extraction
Final voids will have relatively small disturbance areas. One public road, Perretts Road, will be
relocated east around the mining area associated with MLA 50254. The related visual amenity
consistent with previous descriptions characterising the eastern boundary of the southern lease, of
substantial vegetation should remain, providing measures such as minimal vegetation clearing are
carried out.
Disturbance areas consistent with MLA 50254 maintain up to 2477 ha may be disturbed for the
purpose of mine excavations and coal mining. Mining areas will be a dynamic component of the
Project, as they will move as the mine progresses. Progressive rehabilitation will reduce the visual
impacts of the in-filled pits, as land will be returned similar to previous land suitability. The design of
the site layout has placed voids in areas where they will potentially blend into the existing landscape.
Progressive rehabilitation will limit visual impacts to short time frames until the end of mine life stage.
At the end of mine life stage bunds will be constructed around all final voids, consistent with the
Technical Guidelines for the Environmental Management of Exploration and Mining in Queensland,
which states that the bund wall should be a minimum of 2 m in height. This is mainly for safety
purposes, but as rehabilitation progresses, they will provide a buffer and reduce potential visual
impacts.
Extraction will involve heavy machinery that may be visible from certain locations around the site. Coal
will create a sharp contrast with the existing environment, which will create potential impacts on visual
amenity values. Sharp contrast with existing environments will arise from dark coloured coal and the
existing natural colours.
Extraction and voids in particular will have significant impacts when they are within line-of-sight for
sensitive receivers. These potential impacts will be limited by the dynamic nature of these
disturbances and progressive rehabilitation of the bunds surrounding the final voids.
Spoil Dumps
Spoil dumps will likely become the most prominent feature of the Project site. Like the mining pits, they
will be dynamic and will change as the mine progresses. The final rehabilitation plan for dumps will be
detailed in the EIS and Environmental Management Plan (EM Plan). Conceptual planning has
assumed the final slope of the overburden dump face to be between 14 and 17 percent depending on
the competency of the waste material.
Visual Amenity Assessment 31 November 2012
The greatest visual impact is expected at the end of mine life. Although sizeable features of the
Project site, spoil dumps will be rehabilitated progressively, which will limit the time those impacts will
be significant.
Mine staging will have a considerable bearing on the severity of impacts from spoil dumps. Spoil is
initially stored in out-of-pit spoil dumps, located in the south-west corner and north along the western
boundary, to accommodate the mining pit and during this period the out-of-pit spoil dumps will
increase in size quite quickly. The southern ex-pit dump is expected to reach a maximum height of
60m above the original topography before progressive rehabilitation commences, reducing overall
disturbance areas and blending the surface into the surrounding environment. During rehabilitation of
the southern ex-pit, in-pit methods are utilised. In-pit dumping will be scheduled to maximise the area
at RL250 before continuing to dump higher, where a maximum height of RL300, approximately 55 m
above original topography, will be employed, relieving the visual impact from ex-pit utilisation.
Mine Infrastructure Area
The MIA has a range of varied structures located within it. The MIA is located approximately 35 km
north-west of the Wandoan township. Analysis has determined the MIA should not conflict with
regional outlooks from the Wandoan township as distance, current vegetation and existing
disturbances consistent with the adjacent mining tenements and operations render the Project’s visual
impact insignificant. The MIA, located in MLA 50270, shall be most notable from Perretts Road,
adjacent to the eastern boundary. However, as the site is in close proximity to numerous other,
unrelated, mining activities, receivers shall be desensitised to the location of the MIA and existing road
side vegetation buffers shall assist in visual amenity.
Operations will run 24 hrs a day; therefore artificial lighting will be predominant throughout the night.
There is a substantial amount of vegetation between residences and the MLA boundary; however,
lighting may cause impacts during night time hours.
Impacts from buildings will depend on the final design specifications of the buildings and in particular
the colours chosen for the exterior of the buildings. Exteriors should be earthy / natural colours to help
blend with the surrounding natural environment.
Tailings Storage Facility
There will be two surface TSFs situated on the Project site, within MLA 50270, in close proximity to the
MIA. The tailings dams shall have a moderate vertical profile for this Project, and are expected to be
approximately 16 m high, possessing a moderate visual significance. Mature vegetation and
surrounding topography will assist in concealing the majority of visual impact associated with both
TSFs.
Haul roads
The main haul road associated with the Project site is identified as MLA 50271, in between the
northern and southern leases. The transport corridor is expected to be approximately 60 m wide.
Although, haul roads and access roads will be visible, they are not expected to have a significant
impact on visual amenity values, due to their lack of vertical profile.
Fugitive lighting has the potential to cause an impact from haul roads, which will be restricted to night
time hours. The effects of fugitive lighting will also be limited by factors such as house orientation,
vegetation and topography. Lighting from vehicles will also be limited to short time frames.
Visual Amenity Assessment 32 November 2012
Other impacts will be increased traffic volumes and size of vehicles using the roads. These impacts
are likely to be minor in terms of visual impact. Impacts can be minimised by implementing a rostering
system for haulage.
Rail and Services Corridor
The rail loading facility is situated within the northern lease, MLA 50270, with the rail alignment
spanning approximately 36 km east to connect with the Surat Basin Rail line. Rail loading facilities
have a low vertical profile and are unlikely to be seen behind existing vegetation. The rail alignment
also has a low vertical profile and will have minimal visual amenity impacts for sensitive receivers
located in close proximity to the rail.
Visual significance of the Rail and Services Corridor will vary intermittently with the transport of
product coal along the rail. At most sensitive receivers, visual amenity impacts will be minimised by
undulating topography and scattered vegetation.
The existing Surat Basin Rail is used by other mining operations in the region and the increase in
volume on the railway is predicted to be negligible, therefore impacts are expected to be insignificant.
Vegetation clearance
Vegetation clearance will have primary and secondary impacts; firstly, existing visual amenity values
will decrease from the loss of vegetation and secondly the vegetation may no longer be able to shield
other disturbances from view of sensitive receivers. Vegetation clearance will create a contrast in the
landscape and a change in surface structure. Many areas where vegetation clearance occurs
(particularly voids and spoil dumps) will be rehabilitated progressively, which will reduce the contrast
between existing landscapes and future landscapes. This will return the colours and tones of the
environment to a state similar to pre-mining.
Vegetation will play an integral role in mitigating the potential impacts from the Project.
4.2 LIGHTING FROM THE PROJECT
The Project will utilise artificial lighting during night hours around certain infrastructure and vehicles.
This will primarily be located within the MIA, CHPP, loading facilities and power generating sites. The
affects of artificial lighting will be restricted to night time hours and is likely to primarily affect
surrounding residences. Potential affects or impacts will also be influenced by the prevailing climatic
conditions. It is likely that lighting will be visible from surrounding residences. To accurately distinguish
where the effects of lighting will be greatest, an in depth analysis will need to be conducted from inside
and around each residence.
4.3 MINE STAGING
Mine staging is going to have a significant bearing on the magnitude and extent of landscape change
from disturbances and associated potential impacts. Disturbance areas (spoil dumps and voids) will
increase and change location as production rates increase. Figure 8 illustrates the production rates of
ROM coal for the Project operations. Production rates are anticipated to be consistent throughout the
life of the mine with up to 8 Mt of ROM coal expected to be mined pa to produce on average 5 Mt/pa
of product coal for export.
Target commencement date for production is mid-2013, with the mine life estimated to exceed 25
years. The ML for both mine operations and transport will cover an area of approximately 4460 ha.
Visual Amenity Assessment 33 November 2012
The area of land disturbance is estimated to be approximately 3312 ha over the life of the Project,
based on a prefeasibility mine design.
The magnitude of disturbance areas within MLA 50254 (the southern lease) is not anticipated to
exceed approximately 2477 ha, including the open-cut pit and overburden dumps, whereby a final
rehabilitation plan will be detailed in the EIS and EM Plan defining progressive rehabilitation and end
of mine life vertical extents of waste dumps. In addition, the diversion of Horse Creek will see a
proportion of the disturbance on MLA 50254 become apparent early within the life of the mine as
Horse Creek is progressively diverted during the early years of mining, using both temporary and
permanent diversions.
The disturbance areas owing to MLA 50270 (the northern lease) shall be consistent with the CHPP,
two surface TSFs and one void TSF, mine infrastructure and train loading facilities and is not
anticipated to exceed approximately 342 ha of disturbance, as consistent production rates shall not
require upgrading of the mine infrastructure. Associated TSFs shall be augmented as the life of mine
progresses to accommodate production rates; however, progressive rehabilitation of mine areas shall
reduce the overall magnitude of disturbance experienced by receivers from the Project site.
The amount of land clearing conducted within MLA 50271 should be minimal and consistent with the
proposed transport corridor which shall be approximately 60 m wide, to accommodate ROM coal
haulage from the southern to the northern lease. The magnitude of disturbance is not expected to
exceed 15 ha.
In addition, the employment of pro-active vegetation planting, considering the associated time scales
of mine establishment, will provide rehabilitation of disturbed landscapes before the magnitude of
landscape change becomes significant, minimising total disturbance at any one time.

5.0 POTENTIAL IMPACTS FROM THE PROJECT ON VISUAL MANAGEMENT UNITS
5.1 VISUAL EFFECTS ANIMATED
This section presents the visual effects from key locations surrounding the Project in an animated form
to simulate potential visual impacts from the Project. These have been taken from points that
summarise a view of the Project site.
Detailed analysis of aerial photographs, contour maps, road maps and vegetation maps was
conducted in conjunction with receiver locations to determine sites that would best summarise a group
of receivers. Taking this into account, sites have been selected to best summarise the potential
impacts from each side of the Project.
Panoramas have been taken to show the existing conditions and animations have been generated to
show the potential impacts of the Project from these same locations. Animations have been generated
for the end of mine life only, due to the amount of vegetation surrounding the site and the difficulty
locating sites with significant views of the Project. If, at the end of mine life, infrastructure is not visible
then only the existing landform panorama will be presented.
Spoil dumps will have more severe impacts when they are earthy brown, but because these
animations are produced for End of Mine Life stage it is likely that these areas would be released for
rehabilitation at this stage. This will be the spoil dumps final position and mining will have ceased at
this stage. Animations of spoil dumps have been rendered in green because this is how they will
appear shortly after progressive rehabilitation has commenced and they will remain in this condition
for some time.
Animations have been produced for End of Mine stage because for the majority of sites no other
stages were visible (see Figures 9, 10, 11, 12, 13, 14 and 15).
These animations provide a detailed assessment of visible components consistent with the Project.
Many of these sites are in close proximity to the Project boundary and show variation that can occur
within the different outlooks associated with the End of Mine stage results for the Project site.
5.2 DESCRIPTION OF PANORAMIC PHOTOGRAPHS AND ANIMATIONS
These animations have been generated to show wide angle (panoramic) views of the Project area
from particular locations. An initial site visit was conducted to take panoramic photographs of the site
so that animations could be generated of mine components. These sites were specifically targeted as
sites that would summarise groups of receivers having high potential to provide significant views into
the Project site and associated mine components. Due to the nature of the site, where the horizon is
often in close range due to either topography or vegetation, mine components were rarely obvious.
As the animations illustrate, the most significant aspects of the Project, the spoil dumps, are mainly
visible when viewing east and west towards the northern portion of the southern lease (MLA 50254)
(see Figure 10 and Figure 12).
The landscape is particularly sensitive to visual amenity impacts in areas where vegetation is sparse
and has minimal potential to buffer the Project related visual impacts (see Figure 10). There are also
areas in the vicinity of the Project site where landscape aspects, including topography and vegetation,
provide substantial buffering for Project related visual impacts, such as the Mine Infrastructure Area
(see Figure 11).
Visual Amenity Assessment 35 November 2012
The key factors are the amount and size of existing vegetation around the site and on existing
properties and the density of wind breaks along roads, road reserves and property boundaries.
Sections of disturbances, in particular from spoil dumps will likely be visible from some residences,
although these are likely to be moderate to minor.
Figure 9
Panorama taken from site VA2, situated along Bundi Road, shows elevated in-pit spoil dumps. The
spoil dump is visible at this location at the End of Mine stage above the surrounding vegetation, but
due to the distance involved it appears very low on the horizon. Views of the mining void are obscured
by the rising topography, which shall benefit sensitive receivers in proximity to VA2.
Figure 10
Panorama taken from site VA3, situated west of MLA 50254. This site probably experiences the most
significant impacts from the Project. The existing landform is large pastoral sections fringed by
vegetated wind breaks, which do not provide extensive visual amenity. However, spoil dumps in this
region are located at distance from any major roads.
Figure 11
Panorama taken from site VA5, along Goldens Road, situated west of MLA 50270. This site provides
outlooks towards the MIA and the southern tailings dam (Dam TDN) towards the north-east. This site
is fairly typical of a number of sites surrounding the Project, where disturbances are visible but only
through small gaps in vegetation. Impacts to receivers are likely to produce a moderate impact due to
the vegetation’s effect on views of the Project. Views of disturbances from these sites will vary from
each location around this area, but are likely to be similarly intermittent or irregular views.
Figure 12
Panorama taken from site VA9, along Ryals Road, situated east of MLA 50271. This site provides a
view of the extensive vegetation barrier between sensitive receivers, using Ryals Road, and the mine
haul road (MLA 50271). Although the main pit and its neighbouring in-pit spoil dump are located in
view of the horizon, creating moderate visual impact, vegetation does provide extensive buffering
which will shield sensitive receivers from haul road vehicles and their associated lighting during twilight
operations.
Figure 13
Panorama taken from site VA13 provides a view from the local school and several residencies. This
view is associated with the West Surat Link. The view south presents a ridge line which effectively
curtains any intermittent visual disturbance from the proposed rail link. Visual disturbances, due to the
link, directly south are vague along the horizon and only present a slight impact.
Figure 14
Panorama taken from site VA7, situated along Perretts Road north of MLA 50270. This site shows the
view looking south to the proposed Rail and Services Corridor and towards the Project MLA from north
of the ridgeline approaching the Project. As shown in this panorama, neither the West Surat Link nor
the Project MLA is visible from this location due to the present ridgeline. There are two residences
located in this area that may gain views of the West Surat Link, but are unlikely to gain significant
views of the Project.
Visual Amenity Assessment 36 November 2012
Figure 16
Panorama taken from site VA15, situated along the Leichhardt Highway, provides a summary of the
visual impacts upon sensitive receivers along a populated and frequently used portion of thoroughfare
associated with the West Surat Link. Views south towards the associated rail system from the
Leichhardt Highway are obscured by the immediate topography. Scattered vegetation will also assist
in disguising the intermittent use of the West Surat Link.

5.3 LEVEL OF SIGNIFICANCE FOR RECEIVER VMUS
This section highlights groups that have been determined to potentially be significantly impacted upon
by the Project. Residential receivers are considered to be the most sensitive receptor group owing to
their proprietary interest and their prolonged exposure. Recreational receptors have a shorter
exposure to potential impacts but are also considered to be sensitive due to the value they place in the
landscape. Transient users (users of trains or roads) are of moderate sensitivity as they pass through
the Project area intermittently. The least sensitive groups are those already affected by a similar type
of visual impact, for example workers at adjacent mines. The level of significance for Receiver VMUs
is summarised in Table 8.
Factors taken into account when determining the level of significance are the total number of
receivers, their distance to the disturbance, the magnitude or extent of landscape change and the
sensitivity of receivers.
Townships, settlements and places of work in the area have the potential to be significantly impacted
on by the Project. This is primarily due to the value they place on their surrounding visual values and
the duration for which they are exposed to disturbances. Receivers using main roads and in particular
Perretts Road have the potential to be moderately impacted on by the Project. Disturbances along
Perretts Road are in close proximity to receivers and there are a moderate number of receivers.
However viewers using these roads have an intermittent exposure to disturbances and place a lower
value on visual values while using these roads. Other roads and rural grazing users have a slight
potential to be impacted by the Project.

Table 7 (Section 3.5) was used to determine levels of significance for landscape impacts. The
assessment was based on combinations of landscape sensitivity (the nature and value of any
landscape resources likely to be affected and the character of the landscape and its ability to
accommodate change) and impact magnitude (extent of loss of beneficial components or addition of
inappropriate components). Results are presented in Table 9 below.

5.5 SUMMARY OF IMPACTS
The areas that are likely to be exposed to the most significant impacts are residences located in close
proximity to the Project and Rail and Services Corridor, and receivers on Perretts Road. Receivers
using Perretts Road will be exposed to disturbances associated with the Project intermittently.
Receivers situated more than 5 km from the Project site are likely to experience only slight impacts.
Spoil dumps will be the most substantial component from the Project and will likely cause the most
significant impacts on visual amenity values. The transport corridor joining the northern and southern
leases will be visible from Perretts Road and possibly in various places lacking vegetation buffering
along Ryals Road which will create intermittent exposures to receivers.
Visual Amenity Assessment 46 November 2012
The MIA will potentially be visible from Goldens and Perretts Road, although it is not likely to produce
a significant impact due to its vertical scale and the amount of vegetation present. The most significant
impacts will be to residential receivers and receivers using main roads in the Project area.
Both surface TSFs will be potentially visible from residences located to the west of the northern ML,
however, this land form is not expected to exceed 16 m in height.
The Rail and Services Corridor will likely be visible from residences located in the vicinity of Perretts
Road where it approaches Cattle Downs Road, and on Kabunga Road where it approaches the
proposed location of the Corridor.
The potential impact from lighting is restricted to night time hours. Light will be visible from certain
viewpoints; during this time potentially affected receivers will likely be indoors and the effects will be
limited. The amount of surrounding vegetation will also limit the potential impact from artificial lighting.
Components of the Project (particularly out-of-pit spoil dumps) will be visible from locations around the
site and they will have impacts on visual amenity values. However many of these impacts are
predicted to be moderate as shown in Section 5.1. The main area that will be affected will be along
sections of Perretts Road and west of MLA 50254 as the topography is generally flat. South of MLA
50254, viewing north onto the Project site (photo site VA2), a vertical profile of approximately 50 m
does not appear to be significant at more than ~1 km away along the Bundi Highway. In addition,
receivers are protected from significant visual impacts concerning the mining void, throughout the life
of the Project, as existing vegetation conceals the pit.
Visual Amenity Assessment 47 November 2012
6.0 MITIGATION OF POTENTIAL IMPACTS
The potential impacts of the Project on visual amenity values are predicted to be moderate based on
the analysis conducted in this report. Some sites may have line-of-sight views of Project components,
but the majority of impacts are not predicted to be significant. The gentle topography does not provide
any views that overlook the Project and because of this the components of the mine appear minimal
on the horizon (as seen in Section 5.1). The impact may be mitigated by the nature of the existing
surrounding environment and in particular existing vegetation. Vegetation should remain intact along
important buffer zones to mitigate any potential visual impacts.
6.1 GENERAL OVERVIEW OF THE PROJECT SITE
The Project site has been divided into four sectors that have been categorised according to their
sensitivity to landscape changes associated with the Project. This will assist in identifying areas that
have the potential to buffer and those that are more sensitive to the visual amenity impacts associated
with the Project.
The first of these areas is the southern MLA 50254, which includes the majority of the mining
operations, with the exception of the CHPP facilities. The central area, the transport corridor (MLA
50271), joins MLA 50254 to MLA 50270 and contains no static mining infrastructure but will be used
for the transportation of ROM coal from the pit to the CHPP. The northern MLA 50270 area will house
the CHPP and other associated mine infrastructure including tailings storages and the accommodation
village (refer to Figure 16).
The fourth of these areas is consistent with the least amount of disturbance upon operational land; the
planned Rail and Services Corridor termed the West Surat Link. This will connect the northern lease,
MLA 50270, with the Surat Basin Rail, approximately 36 km away, to the north east of the Wandoan
township.
This section will identify which components of the Project are located in these areas.

Visual Amenity Assessment 49 November 2012
Southern MLA 50254
The southern MLA (50254) encompasses the largest area of disturbance occupied by the Project. It
contains the area of Mining associated with the open-cut pit and two out-of-pit dumps, one located in
the south-west corner of the lease, the other nearing the north. The operations of the southern lease
require the diversion of Horse Creek and Perretts Road and may potentially affect the visual amenity
of sensitive receivers such as residencies and those utilising local roads, such as Bundi or Perretts
Road, particularly within 1 km from the mining lease boundary.
There are 12 sensitive receivers within 5 km of the southern lease boundary that are buffered by
various degrees of vegetation. Sensitive receivers south of MLA 50254 are subject to significant visual
impacts associated with mining operations and stockpiles. Sensitive receivers located to the east of
MLA50254 are provided with substantial buffering along Ryals Road and those located west are
provided with only sparse coverage as historic clearing has left the landscape with substantially
exhausted vegetation.
Existing vegetation, topography and ground structures may be of visual amenity to potentially affected
sensitive receivers. The associated visual amenity correlated with the out-of-pit dumps is best
represented by photo sites VA4, VA3 and VA2.
Patchy vegetation is located at distance from the mining lease boundary, helping to reduce the visual
impact of landscape changes. On approach to the southern boundary vegetation provides sufficient
buffering of mining disturbances.
The eastern boundary provides very little vegetation to buffer the view of the out-of-pit dumps.
However, the typically flat topography does not provide any substantial viewpoints down onto the
Project site and patches of shrub land will provide moderate buffering.
The area of mining encompasses the majority of the southern lease and the anticipated visual amenity
provided by vegetation and existing landscapes is best represented by photo sites VA2, VA3, VA4,
VA9 and VA10.
Scattered vegetation owing to VA9 shall provide good visual amenity from the northern section of the
southern lease, which houses one out-of-pit dump and associated open pit disturbances. VA10 shows
substantial road side buffering along Ryals road whilst VA2 shows minimal buffering from Bundi road
looking north. Dense vegetation provides buffering along the southern boundary.
Topography and vegetation surrounding the southern lease generally has the ability to buffer
moderate levels of landscape change associated with mining disturbance. However, west of the lease,
where the landscape is predominantly non-remnant grassland there is minimal buffering capacity to
the visual amenity impacts associated with the Project.
Central Transport Corridor MLA 50271
The central lease is responsible for minimal ecological disturbance associated with the Project. No
static mine infrastructure is anticipated within the transport corridor. This area will be used primarily to
transport ROM coal from the southern lease pit to the CHPP within the northern lease.
The main associated disturbances within the central lease shall be large machinery necessary for the
transportation of ROM coal. The projected visual amenity is best represented by photo site VA9 which
shows exceptional vegetation buffering located alongside Ryals Road and into the horizon.
Visual Amenity Assessment 50 November 2012
There are 2 sensitive receivers located within 5 km of the transport corridor; in addition receivers may
also be associated with Perretts Road which runs north to south adjacent to the central lease
boundary. Although variable between receivers, distance from disturbance along with subsequent
buffering and intermittent use of the transport corridor should facilitate reasonable visual amenity for
such receivers. In addition, flat topography with consistent vegetation provides moderate buffering
capacity to minimise impacts to visual amenity.
Northern MLA 50270
The northern lease is consistent with the MIA, two surface TSFs, the western extent of the West Surat
Link and the anticipated mining village. There are 3 associated sensitive receivers surrounding the
lease with anticipated visual amenity best represented by photo sites VA8, VA7, VA6 and VA5.
VA6, located towards the southern end of the northern lease, facing east, displays scattered
vegetation on undulating hills. However, a clear view of the horizon and the associated elevated
topography may provide views of the various elements associated with this portion of the mining
lease.
VA5 is located closer to the mining lease along Goldens Road. There is minimal vegetation buffering
associated with this view onto the northern lease, however, only one sensitive receiver is in close
proximity to this location (approximately 2 km from the lease boundary). Visual interference from the
associated mining infrastructure may be experienced.
VA8 and VA7 look south-west onto the northern portion of the lease, where associated infrastructure
will include the western end of the West Surat Link, the mining village, Dam TDN further south, and
Dam TDNA to the west. These photo sites were located on Perretts Road and demonstrate, on
approach to the Mining Lease boundary, elevated topography and existing agricultural infrastructure
which will assist to buffer the view of mining infrastructure from a distance. As Perretts Road continues
within close proximity to the eastern boundary of the northern lease visual amenity is also protected,
although minimally, via elevated topography.
West Surat Link
There are many sensitive receivers associated with the West Surat Rail Link as the Link spans
approximately 36 km, through (approximately) 21 properties, connecting to the Surat Basin Rail, north
east of the Wandoan township.
The ability of landscape aspects, such as topography and vegetation, to buffer landscape changes
associated with the West Surat Link is best represented by photos VA11, VA12, VA13, VA14, VA15,
VA17 and VA18. The eastern portion of the link is characterised by predominate vegetation cover
along Kabunga Road in both, north and south directions. Scattered trees and uneven topography
protect sensitive receivers located in close proximity (within 1 and 2 km) of the link.
VA13 shows the central portion and illustrates the visual amenity provided approximately 1 km from
the West Surat Link, where sensitive receivers, school and residencies are located.
The western end of the West Surat Link passes in close proximity to VA7, located within the 1 km
buffer zone from the Project area. Visual amenity values of the two sensitive receivers located near
site VA7 will likely be impacted, albeit not significantly, by the WSL and associated Corridor
infrastructure. Topography and scattered vegetation minimise visual amenity impacts for these
receivers.
Visual Amenity Assessment 51 November 2012
As viewed a small embankment is provided between sensitive receivers and proposed disturbances.
The associated colour contrast associated with cleared pastures and scattered vegetation should
provide buffers to assist in visual amenity.
Views from the Leichhardt Highway are represented by photo sites VA14, VA15 and VA16 and
incorporate the visual amenity experienced by sensitive receivers located within 2 km of the West
Surat Link.
Undulating hills, scattered trees and sparse vegetation provide contrasting aesthetics that provide a
filter for receivers associated with the eastern portion of the rail link.
VA16 illustrates how dynamic the landscape is in relatively small and seemingly unrelated portions.
Viewing east along the proposed rail location, the visual amenity is represented by embankments,
scattered trees and disjointed vegetation. Although similar, viewing west along the proposed location
of the link, the landscape is characterised by large clearances and sparse vegetation.
However, it is these landscape aspects, variable topography and the assortment of vegetation
configurations that provide buffering to the visual amenity impacts associated with the proposed Rail
and Services Corridor. The landscape associated with the eastern extent of the link, where the
connection is made to the Surat Basin Rail, is characterised by scattered vegetation and existing
agricultural infrastructure.
Furthermore, the proximity of sensitive receivers to the existing Surat Basin Rail may desensitise
receivers to the development of the proposed rail link.
6.2 ROADS
The Leichhardt Highway has a high number of short term or intermittent receivers and is in close
proximity to the West Surat Link associated with the Project. However, it was identified that there are
less than moderate impacts on the values associated with the highway from the West Surat Link.
Existing intact vegetation buffers where present should remain intact throughout the life of the Project,
further reducing any potential visual impacts from intermittent locomotive use.
The impacts associated with Bundi Road, Perretts Road and Ryals Road are expected to vary, as
potential impacts will be consistent with the associated vegetation buffering and topography owning to
portions of the roads. However, exposure to mining related activities shall only be intermittent while
driving and many of the roads surrounding the Project site have only a small number of people using
them.
The majority of roads around the Project site have vegetation buffers present. These buffers create a
closed in view for receivers (refer to Photo Plate 19). Vegetation buffers also surround the Project site
which will further reduce potential impacts.
Visual Amenity Assessment 52 November 2012
Photo Plate 19 Dense vegetation buffer from Ryals Road towards MLA 50254 and the transport
corridor (refer to VA9 Figure 4)
Newly constructed roads from the Project will likely have a limited impact on visual amenity values due
to the limited vertical profile. The impacts from new roads will be mitigated by the low vertical profile
and the nature of these types of disturbances.
6.3 MINE COMPONENTS
One of the major features of the Project that may potentially impact on visual amenity values are the
spoil dumps. It has been assumed that the southern out-of-pit spoil dump will remain less than 60 m,
while the in-pit spoil dump may reach a height of between 40 m – 60 m. These dumps will become
dominant features of the Project site. The amount of material that reaches the out-of-pit spoil dumps
will be minimised by the utilisation of in-pit spoil disposal methods.
Out-of-pit spoil dumps from the Project have been located in areas where landscape aspects provide
buffering of the visual amenity impacts associated with the spoil dumps. Locating spoil dumps in these
locations will help to: (a) shield the dumps from view for residences located behind naturally raised
areas of the Project site, and (b) help the dumps to blend into the surroundings by having similar
topography to the existing landscape.
Spoil will be dumped into the mining pits, which will greatly reduce the height of the out-of-pit spoil
dumps. Both in-pit and out-of-pit spoil dumps are to be progressively rehabilitated as the mine
progresses. Progressive rehabilitation will utilise local species, which will help the dumps to blend into
the surrounding landscape. It will also restrict the timeframes that receivers are exposed to potential
impacts.
Final voids will have small scale bunds surrounding them (approximately 2 m), which will help to shield
the voids themselves from view. These bunds will be rehabilitated as per the rest of site. The potential
impact on visual amenity values will be affected by the dynamic nature of the voids and will likely be
limited to short time frames for many locations. In addition, as seen in Figure 9, the existing landscape
aspects have the potential to buffer the visual amenity aspects associated with the final void. The mine
infrastructure area is not likely to have a significant impact as it is not in close proximity to surrounding
residences. However, potential impacts will be reduced by the embankment and vegetation, although
this will depend on the amount of vegetation left intact and the types of infrastructure present.
Visual Amenity Assessment 53 November 2012
The alignment of the West Surat Link (WSL) Rail and Services Corridor will impact, to some extent,
visual amenity values. The Corridor passes in close proximity to sensitive receivers located on, or in
the vicinity of Perretts Road approaching Cattle Downs Road, and Kabunga Road approaching the
proposed location of the Corridor. Despite variable topography and vegetation providing a degree of
mitigation, some impact on visual amenity values is likely to be experienced.
6.4 OUTLOOKS, VIEWING POINTS AND WALKWAYS
There are no existing viewing outlooks associated with the Project area. The primary land use of the
surrounding environment is low intensity cattle grazing and cropping, which will likely continue
throughout the life of the Project. There are some gentle ridgelines present, but these are on average
only 20 m – 30 m above the surrounding landscape and are not obvious on the horizon. It is unlikely
that these raised land forms are used for scenic purposes and the majority are on private land, so are
not accessible to the general public.
6.5 WATERWAYS
Horse Creek is planned to be diverted to accommodate the Project. The extent of change in this area
will be significant; however visual amenity impacts are minimal due to the lack of immediate sensitive
receivers. The final permanent diversion system is in place by year 10 and has a total length of 8.5 km
and incorporates three, two metre, drop structures, which cannot be viewed from Ryals Road (see
Figure 12). The final diversion is in place for at least 25 years prior to closure, under the current mine
plan.
The sensitivity of creeks in the surrounding area to visual amenity impacts associated with the Project
is minimal.
6.6 EXISTING RESIDENCIES
Animated panoramas were constructed from locations that summarised a group of properties
prospective views of the Project, including the Rail and Services Corridor. These locations were
selected after detailed analysis of topographical maps, aerial photographs, road closure maps,
cadastral boundaries and residence location maps.
Currently, two residences are located within the Project MLA boundary: one within MLA 50254 and the
other within MLA 50270. A further 12 residences are located less than 1 km from the Project and
Corridor, and are considered highly sensitive due to their proximity. A total of 25 residences are
located 1 – 3 km from the Project and Corridor, and are also considered sensitive due to their
proximity. Six residences are located 3 – 5 km from the Project and Corridor and are considered to
have moderate to low sensitive to the Project. A further nine residences are located more than 5 km
from the Project and Corridor. These residences have low sensitivity to the Project.
The residences likely to experience the highest impacts are those located west of the Project. This is
due to the lack of existing vegetation and the existing topography.
Analysis of aerial photography suggests 7 residences, surrounding the 3 MLAs, may potentially have
views into the Project MLA site. However, animation and photographs from around these sites showed
that although the spoil dumps are visible they are not as prominent on the horizon as predicted (see
Figures 9 and 11).
This analysis is dependent on vegetation adjacent to the Project and vegetation on private residences
either remaining unchanged throughout the life of the Project or increasing in density.
Visual Amenity Assessment 54 November 2012
6.7 PLACES OF WORK
A school is centrally located along the West Surat Link, approximately 20 km from the Project site. The
landscape surrounding the school is protected by a gentle ridgeline and scattered vegetation and as
such the school in addition to the associated residencies, are not predicted to gain significant views of
the West Surat Link or Project site. No other places of work in the region are predicted to be impacted
on by the Project in terms of visual amenity values.
6.8 SENSITIVITY OF THE LANDSCAPE TO VISUAL AMENITY IMPACTS OF THE PROJECT
The existing nature of the site is open scale pasture with wind break vegetation around the perimeters
and along roads. The open, sparsely vegetated areas of the Project site have the potential to provide
some buffering to visual amenity impacts associated with the rehabilitated Project site. Post-mining
land forms will be raised from existing levels, but will be returned to a condition similar to pre-mining. It
has been assumed that in-pit spoil dumps will raise areas of the Project site by between 40 – 60 m.
Vegetation buffers on Project boundaries will also help in minimising the sensitivity of the existing
environment to visual amenity impacts.
There are a number of exploration and mining leases surrounding the Project, which will desensitise
certain viewers to the Project. Coal operations are common in the region and provide a valuable
economic input into the community. The Surat Basin contains numerous EPCs and the region has
been exposed to mining activity for several decades. There are also several MLs within close
proximity to the Project site. This region has been exposed to exploration and mining operations for
the past few decades, which could potentially desensitise some receivers to the Project.
Project design has placed key mine infrastructure and landforms in areas where aspects of the
existing landscape provide a natural buffer. Efforts have been made to place dumps alongside high
points and ridgelines so they will not significantly raise the landscape from its existing level. Once
rehabilitated modified landscapes should blend into the surrounding environment and have a similar
final appearance. They will however be at a slightly raised level. Much of the infrastructure such as
dams have been located in low points around the Project site, primarily for functional reasons, but this
will also mitigate their visual impact.
6.9 BUFFER ZONES SURROUNDING THE PROJECT
The Project is predicted to take several years before the extent of landscape change becomes
significant. Planting of buffer zones along boundaries, especially those located west of the (southern
lease) Project area, and allowing existing buffer zones to increase in density, will help to
militateagainst potential impacts on visual amenity values, by shielding the receivers from the Project
or breaking up potential views of the Project. Plantings can take up to 20 years to become mature, but
after about 10 years they will begin to assist in breaking up views of the Project.
Natural regeneration or planting along affected buffer zones could reduce the impacts in this area, but
any potential mitigation will take several years before it becomes effective. The Project has a life span
of 32+ years, so this strategy could be beneficial for the later stages of the Project.
6.10 LIGHTING
If light sources are located within 1 km from sensitive receivers and in direct line of sight, it is
recommended that directional lighting be used and be directed away from receivers. Lighting hoods
can also be utilised to shield these residences if necessary. This will be reliant on further analysis from
individual residences to determine the appropriate mitigation strategy.
Visual Amenity Assessment 55 November 2012
7.0 SUMMARY
The potential impacts on visual amenity values from the Project on the surrounding environment have
the potential to create a significant impact depending on the circumstances of the receiver. For the
majority of receivers the distance from the Project and the amount of mature vegetation surrounding
the site will be sufficient to mitigate any potential impacts that occur within the Project. Other receivers
will have potentially significant views of disturbances associated with the Project and will require
further in depth analysis. The topography of the site will help to shield receivers from certain elements
of the Project, while increasing the exposure of others. Progressive rehabilitation of the site will help to
blend features into the surrounding environment and significantly reduce the potential impacts on
visual amenity.
The effects of topography at the site are generally beneficial to the Project as the horizon is often
difficult to distinguish from viewing distances of more than 2 – 3 km. The combination of topography
and vegetation is likely to reduce the potential impacts for many receivers. It is predicted that existing
topography will be exaggerated by spoil dumps rather than changing them significantly. Sites in the
south eastern vicinity of the Project, including the final void, will likely have lower impacts due to the
site being shielded from many of the residences from raised topography and vegetation. The Project
landscape and associated views are not of significant national, state, regional or local value and is
reasonably uniform with the wider region. The existing gentle rolling topography is typical of the
surrounding rural grazing landscapes. The range in topography at the Project site is approximately
50m.
Mine staging is going to have a significant bearing on the extent of impacts of the Project on
surrounding receivers. The Project has a 21 month construction period, before operations begin to
satisfy the production of 8 Mt of ROM coal per annum. Due to the relatively shallow depth of the first
coal in the mine schedule minimal time is needed to establish a working face and working room to
mine coal. It is anticipated however to take 15 months to ramp up to the full annual mine production
rate of approximately 8 Mtpa ROM. With operations ramping up over time it is possible to implement
mitigation measures like planting, before the disturbance areas increase.
It is recommended that all vegetation remain intact surrounding significant disturbances from the
Project. In some areas it may be possible to plant vegetation, due to the time available with mine
staging. Managing vegetation effectively will also help to preserve and improve existing remnant
vegetation.
Receivers using non-constructed roads, in close proximity to the Project, are predicted to be
moderately impacted. However, these instances will be of limited occurrence as non-constructed
roads are normally not used by the general public.
Visual amenity values of sensitive receivers situated in close proximity to the West Surat Link are
likely to be impacted. Undulating topography and vegetation will minimise these impacts at some
locations.
The single workplace in proximity to the West Surat Link is unlikely to be impacted in terms of visual
amenity values, due to the amount of vegetation present, landscape form and distance from
disturbance. There are no public lookouts in the area. Gentle ridgelines and hills are present in the
area, although these are not likely to create significant viewpoints as potential users are limited to local
residents.
Perretts Road is quite sensitive to visual amenity impacts, due to its close proximity, impending
diversion and the lack of vegetation in some sections. Other roads in the area such as Goldens Road
Visual Amenity Assessment 56 November 2012
which will undergo closure and connection to Cattle Creek Road are also considered to be sensitive,
although increasing vegetation buffering will help minimise the sensitivity of these roads to the visual
amenity impacts associated with the Project.
The value of existing vegetation surrounding the Project is a vital aspect in reducing potential impacts
on visual amenity values. It is highly recommended that vegetation be left intact where possible, as it
will provide a visual buffer around large parts of the Project. This visual buffer could also be extended
with planting to cover further areas of the Project boundary. Even if the buffer zone surrounding the
Project is minimal it will still help to buffer the visual amenity impacts associated with the Project.
Established vegetation surrounds a large proportion of the Project, with the exception of the western
side, adjacent to MLA 50254, which would benefit from the establishment of vegetation buffering.
