construction materials at Shackley Hill near Sheffield, as well as several smaller
intermittently operated quarries, including the recently purchased Forthside
quarry.
A5.2 Inert waste landfill operating experience The company has nine years experience in operating inert waste landfills at both
Hillcrest Road in Devonport and at the Shackley Hill Quarry. Treloar Transport
has received no public complaints, Environmental Protection Notices from the
EPA, or adverse comment from Local Government regarding the operation of
these landfills.
The Hillcrest Road landfill and resource recovery centre has a similar intake to
that proposed for the Forthside Quarry landfill. It is located in a Light Industrial
Area of Devonport in close proximity to residential areas.
Part B Project description B1 Description of project The project is located on ML 1704 P/M, which is located at the end of Forthside
Road, in the locality of Forthside, which is 5.3 km SSE of Forth. The lease
contains an active Level 1 quarry, licensed for up to 5000m3 of extraction per
annum.
Mining Lease Details: Lease number: 1704P/M Lease area: 12Ha Lease holder: Treloar Transport Pty Ltd Land ownership: J and A Treloar Superannuation Fund 8.081Ha; Crown 3.919 Ha

Figure One shows the Mining Lease and the proposed development. There is a history of extractive industries in this locality dating back to perhaps the 1950s, and there are a number of disused quarries previously operated by Devonport City Council adjoining this site, some under rehabilitation. The site itself is heavily impacted by previous operations, with unsustainable landforms (steep, erodible slopes), erosion gullies, siltation of existing sediment control structures, and relatively large areas of unrehabilitated disturbed ground. Treloar Transport has recently purchased the Mining Lease and associated freehold land from the previous owners who operated the site intermittently, so having the site actively managed with commitments to improved water management and progressive rehabilitation should lead to improved environmental outcomes. Sections of the Lease will be used as a landfill site for construction, demolition
and solid inert wastes. Typically, material will include excess spoil or excavated
unsuitable material and will comply with the listing of materials suitable for a
Category A Landfill in the Landfill Sustainability Guide, 2004.
B2 Demand for proposal Treloar Transport has an existing inert waste landfill at Hillcrest Road in
Devonport. It is one of the four licensed landfill sites on the North West Coast in
which general inert landfill is recycled and re-used throughout the construction
industry.
However, this landfill is approaching the end of its useful life, hence the need for
this replacement landfill at Forthside. There are no other available inert waste
landfills in the Devonport area, and minimising the transportation distance of inert
waste is environmentally responsible.
Based on existing demand at the Devonport landfill, it is estimated that delivered
volumes will be 10,000m3 (15,000 tonnes) per annum. Half of this material will be
from Treloar Transport’s own civil construction projects, with the balance being
from other civil and building contractors and the general public.
6
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
Experience gained in operating this landfill for eight years gives an indication that
approximately 20% (3,000 tonnes) of the delivered waste material may be
suitable for reuse, for example as clean fill for other projects, reusable roadbase
materials, and topsoil.
A key advantage for an inert waste landfill being operated by a civil contracting
company is that the company will typically have several projects under
construction at the same time, and can switch material between projects. Reuse
of materials can sometimes be planned in advance. These opportunities for
reuse do not necessarily arise at landfills under the control of municipal bodies or
a third party.
A further advantage is approximately one third of trucks that delver waste
material will collect replacement quarry product – this serves to minimize truck
travel distance and consequently greenhouse gas generation.
B3 Operating method B3.1 Prevention of unauthorised access: Forthside Road is the only access to the site, which is surrounded by steep,
heavily forested terrain, precluding any other access. Note that traffic flows on
this road are minimal as it is a “No Through Road” with only one residence past
the Mining Lease.
The entrance to the site off Forthside Road will be secured out of hours by a
substantial locked gate.
B3.2 Screening of loads: Approximately 50% of the loads will be from Treloar Transport civil construction
projects. This material will be under the control of the company from source to
disposal, with the originating project supervisor screening the material at
generation.
7
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
The balance of the incoming materials will be from other civil contracting firms
and building contractors (45%) and the general public (5%). The site will be
manned at all times whilst accepting waste from other than Treloar Transport.
Incoming trucks must report to the operator and declare the contents of the load.
Loads whose contents are not known to the driver will not be accepted. All loads
will be inspected by the operator prior to dumping, with the customer’s details
obtained for future reference if a problem is found with the load later. Treloar
Transport commits to removing from site to an appropriate landfill any unsuitable
loads dumped accidently.
B3.3 Operating hours: Operating hours will be as per the existing extractive operation, 0700 to 1700
Monday to Friday and 0800 to 1200 Saturday. The site will not be worked on
Sundays or Public Holidays, unless an exceptional circumstance exists and
permission is obtained from the EPA to work on these days as a short term
measure only.
B3.4 Timeframe of project The project will require some initial development work if approval is given,
namely the development of an access road into the landfill area, installation of
security gates, installation of settling ponds and preparation of the landfill area to
receive material e.g. diversion drains, removal of loose saleable material.
However, this minimal infrastructure would only take a month to install before the
project could commence.
B3.5 Waste types and quantities involved The landfill will typically receive material complying with the listing of materials
suitable for a Category A Landfill in the Landfill Sustainability Guide, 2004.
• Materials will include:
8
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
• Rock
• Earth
• Clay
• Soils
• Roadbases and gravels
• Inert demolition rubble – bricks, concrete
Based on historical deliveries at the Hillcrest Road landfill, it is anticipated
deliveries at the Forthside Road landfill will amount to 10,000m3 (15,000 tonnes)
per annum, with perhaps 20% of the material being reusable by Treloar
Transport, leaving a nett importation of 12,000 tonnes. The relative composition
of the received materials is variable depending on projects under development.
This results in a net delivered volume of 8,000m3 (12,000 tonnes) per annum.
However, when this material is delivered it is at an average bulk density of
1.5t/m3, compaction from trucks and the loader working over it will increase its
bulk density to 2.35t/m3, reducing the volume to 5,100m3. This proposal is for a
10 year project life (120,000 tonnes), although the site has a potentially longer
life as a landfill.
Received material will be dumped in 2m deep lifts, and compacted by dozer,
wheel loader, and trucks driving over the dumped material. If some material is
failing to compact successfully, then a Treloar Transport roller can be transported
onto site to compact the material further.
B4 Need for the project
Treloar Transport Pty Ltd as a civil construction business generates inert
construction waste that requires disposal off the project sites. As outlined above,
Treloar Transport’s Hillcrest Road landfill in Devonport is nearing the end of its
useful life - the Forthside landfill is intended as a replacement location, not as an
additional landfill.
9
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
Dedicated inert waste landfills help to preserve public putrescible landfill
resources by diverting material for reuse or into Type A landfills that are simpler
to operate, require less buffer zone, and require less leachate management.
The closure of the Hillcrest Road facility in the next two years will leave
Devonport without a dedicated inert waste landfill, with the nearest facility being
at Ulverstone. This would lead to longer transportation distances for Devonport
based businesses to dispose of inert waste, with a consequent 10,000 km
increase in the distance travelled by trucks to dispose of waste and greater
greenhouse gas generation.
B5 Alternatives to the proposal Alternatives to the proposal include transporting material to Ulverstone or
developing a new facility on an alternative site. The environmental issues
involved in longer transportation distances are detailed above in “Need for the
project”.
This site is already heavily disturbed, and this project will involve a minimum of
further disturbance. The Mining Lease under previous ownership was operated
solely as a Level 1 quarry; runoff and sedimentation control works and
progressive rehabilitation will actually improve the physical environment of the
site. This is preferable to starting a landfill in an undisturbed area. There is
considerable synergy in terms of operating the inert waste landfill in conjunction
with a civil construction materials quarry it minimizes the transportation distance
required to collect replacement construction material, maximizes waste reuse,
and the layout of the quarry means that resource sterilisation is avoided.
B6 Waste hierarchy The Stubbs Road site, under the control of a civil contractor such as Treloar
Transport Pty Ltd, is ideal to maximize the potential of reusing material in
compliance with the waste management hierarchy. For example, topsoil stripped
from subdivision road paths can be reused in quarry rehabilitation, material 10
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
unsuitable on engineering properties for roadbase may be suitable elsewhere as
a landscaping fill material.
This is a key advantage of an inert waste landfill being operated by a civil
contracting company – the company will typically have several projects under
construction at the same time, and can switch material between projects. Reuse
of materials can sometimes be planned in advance. These opportunities for
reuse do not necessarily arise at landfills under the control of municipal bodies or
a third party.
B7 Working method The ground surface of the inert landfill footprint is covered with patchy regrowth
vegetation, which will be cleared, along with soft erosion debris (which may be
saleable) prior to waste deposition beginning. This will ensure a strong key
between the landfill material and the existing ground surface. A bund will be
constructed along the tipping face toe prior to tipping commencing to act as
“catch all” to retain any slumps of mobile material.
The introduced waste will be dumped in 2m high lifts, starting on the western end
of the lowest bench, and retreating to the east. This material will be leveled and
compacted by wheel loader at the end of each day. As it is inert waste, there is
no need for capping material on a daily basis. Gravel obtained from the quarry
will be spread on the road surface as required to provide a suitable travelling
surface for on road trucks.
The 20% of delivered material suitable for reuse will be tipped as directed by the
site operator onto stockpiles located at the entrance to the working bench. The
site operator will be an experienced civil construction operator, who will be further
trained in recognizing material suitable for reuse.
Truck drivers will be instructed not to tip directly over a face unless provided with
a backstop or a spotter.

B8 Project area B8.1 General description The Lease area is on the crest and southern side of a ridge running
approximately east –west. The catchment valley of Goldie Creek lies at the toe of
the southern side of the ridge, running in a westerly direction. The crest of the
ridge peaks at RL 248, the bottom of the valley of Goldie Creek adjacent to the
western end of the lease is at RL 175. A further ridge, trending in the same
direction, rises higher than the lease just 850m to the south, this ridge cresting at
RL300. The site is thus not visible from any houses to the north, south and east.
The western end of the quarry is visible from Sprent Road, 3.25 km to the west,
see Plate One. The landfill site is not visible from any houses or public roads.
Plate One View of quarry from Sprent Road. (note: 4 x zoom image)
There is one heavily impacted watercourse within the operational area. This
Class 4 stream is the headwater of the Class 2/ 3 Goldie Creek. It does not
exhibit a normal stream flow, being diverted out of its original channel by the
quarry earthworks, and cutting an erosion channel across disturbed ground until
entering the sedimentation dam, see Plate Two. Below the dam it exhibits normal
stream flow characteristics in a relatively undisturbed environment. 12

It is intended to control the existing erosion in this stream by constructing bars
acroos steep sections and using armour rock. The scrubby regrowth will be
cleared by these works and the flow redirected to a diversion drain skirting the
bottom of the proposed landfill.
Plate Two – The Class Four “stream”.
There are no wetlands. Vegetation on the lease is Dry Eucalyptus Obliqua forest,
although 90% of the lease area is cleared or disturbed, with Plate Two also
showing typical scrubby vegetation in the footprint of the landfill.
13
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
Most of the Lease, plus the land adjoining to the east, north and west is exempt
from Land Capability Classification, with the southern fringe of the Lease and
adjoining land being Capability Class 5. Land zoning is Rural.
Figure Three shows vegetation and drainage management.
B8.2 Buffer distances
The nearest residence to the Mining lease is the house owned by G and B
Russell, which is 600m to the south west of the southern lease boundary and
700m from the proposed landfill. This is greater than the recommended distance
in the Landfill Sustainability Guide of 300m.
The proposed landfill also exceeds with the recommended distance to airfields
(14 km to Devonport Airport, recommended buffer is a minimum of 10 km), and it
will be 200m from the permanent flow of Goldie Creek, beyond the
recommended buffer of 50m.
B8.3 Land tenure of the site ML 1704P/M is of Ha12Ha, with 8.081Ha being freehold owned by the JR and AR
Treloar Superannuation Fund, and the balance being leasehold Crown Land
managed by Forestry Tasmania.
The site has no past history of activities that may have caused soil or
groundwater contamination. It is believed the 1970’s was the peak period for
extraction from the site with material being used for Devonport Airport
redevelopment.
The proposed landfill site is on the south side of the Lease, at the toe of an
existing quarry. There is no quarrying activity currently on the landfill footprint,
14
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
with no further extraction of material possible from this area. Due to topography,
the site is obscured from all neighbours.
There is one residence to the south - west approximately 600m from the Lease
boundary. Other residences are more than a kilometre from the site. The closest
significant sensitive use is Forth Primary School which is 4.6 km to the North –
West, and obscured by several ridge lines.
The finished profile of the landfill will have faces battered back to 1:3 (typical of
the existing terrain), with 7m wide benches every 10 vertical metres to minimize
run – off erosion potential. The completed landfill will be rehabilitated with
suitable native vegetation. Erosion and sediment control measures are
incorporated in the design, including clean water diversions above the landfill.
Figure Three is a plan of sedimentation and drainage management.
B8.4 Description of Soils and underlying rock types: The geology substrate for this area is Lts – Precambrian – Forth metamorphics -
Dominantly Quartzite.
Soil description is moderately well drained soils formed from Precambrian
quartzite. A dark grey sapric sandy loam overlies a greyish brown loamy sand
and a massive, bleached sand densipan. There are abundant quartzite stones
throughout the profile.
Erodibility is rated as Moderate to High.
B8.5 Surrounding land use The land surrounding the lease is undeveloped timbered country, owned by the
Crown and administered by Forestry Tasmania on the northern, eastern and
western sides, and the southern side owned and managed by G and B Russell.
B8.6 Current and historical use of the Mining Lease The current use of the Mining Lease is as a Level 1 Extractive Industry – a quarry
producing up to 5,000m3 of subbase gravel per annum. The land zoning is Rural, 15
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
and the majority of the Lease is excluded from land capability classification,
although a portion of the southern side of the Lease is Capability Class 5.
The footprint of the proposed landfill is in an area where the maximum stone
resource has already been extracted, and is not currently used for quarrying.

Figure One is a site plan showing vegetation, topography, roads, drainage and
mining and filling areas.
Figure Two shows traffic management.
Figure Three shows vegetation and drainage management.
Figure Four is a section showing the interaction between the landfill and quarry
plans.
B8.8 Public health
This landfill is strictly for inert waste, with placing of material under continual
supervision. No putrescible (e.g. household waste) or controlled waste (e.g.
tyres, asbestos) will be dumped here. Treloar Transport has a perfect history of
excluding these materials from its Hillcrest Road landfill. The operation of this
landfill will be similarly controlled, with much of the material coming from Treloar
Transport civil construction projects – thus being screened by Treloar Transport
at the point of generation and under control of the company from source to
disposal.
The site will be manned at all times whilst accepting wastes from the public, thus
ensuring all loads are screened. All trucks entering the site will be required to
stop and declare the contents of their load to the site operator, with unknown
loads not being allowed to tip.

Part C Potential environmental effects C1 Flora and fauna Note: The complete flora and fauna documentation, including the Conserve
Report and Eagle Report was compiled by Tas Land and Forest and is in
Appendix One. Note that this report reflects a worst case scenario whereby 0.65
ha of Obliqua forest was to be cleared, Treloar Transport has altered this
proposal whereby the Obliqua forest will only be minimally impacted by erosion
control works, with a maximum of 0.1 ha affected.
Flora: The native forest area at the toe of the landfill keyed out as Dry-hOB - Heathy E.
Obliqua forest – Dry E.Obliqua forest which does not require further protection
under the RFA or Forest Practices process. Therefore it was determined that this
floristic community was not considered a community requiring further protection
through the Regional Forest Agreement or as a Threatened Community through
the Forest Practices Act process.
From the Conserve report there are no known localities of Threatened Flora
Species within the vicinity of the planned clearing operations.
The Common hemp-bush was not noted in field visits across the site.
Fauna: From the Conserve report there are no known localities of Threatened Species
within the vicinity of the planned clearing operations.
There was no identified potential habitat for threatened species that will be
impacted by the planned clearing operations.
The considered Threatened species are as per the Kindred Threatened Fauna
Manual (map no. 4243) under the Forest Practices Authority.
17
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
There are no nesting or den sites located within the planned clearing area and no
Threatened Species will be impacted by the planned landfill clearing areas.
Management prescriptions to maintain downstream water quality are described
below in further considerations.
The full list of potential Fauna Threatened Species that may occur within this region are:-
giant freshwater crayfish – There are no streams within the planned clearing
areas which have suitable habitat for the Giant freshwater crayfish.
There are heavily modified watercourses related to drainage of the previous
quarry works, however, these watercourses do not contain suitable or potential
habitat for the GFC.
australian grayling - There are no streams within the planned clearing areas
which have suitable habitat for the Australian grayling.
For all aquatic Threatened Fauna species it is considered that there is no
suitable habitat that will be impacted by the planned clearing areas.
It is considered important to maintain downstream water quality with specific
management methods.
hydrobiid snail - there are no streams within the planned clearing areas which
have suitable habitat for the Hydrobiid snail, which is not known within this
stream catchment.
eastern barred bandicoot – There is considered to be potential habitat for this
species in the surrounding native forest adjoining the existing quarry. However,
18
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
no specific nesting areas were noted, nor was it optimum habitat i.e. grasslands,
tussock, grassy paddocks, reeds or heath within the planned operational area.
There is sufficient retained native forest surrounding the existing quarry, including
the planned Landfill clearing area to offer sufficient habitat for this species. It is
considered that the clearing of the Landfill area will not adversely impact on the
Eastern barred bandicoot.
quoll (spotted-tailed & eastern) - There is considered to be potential habitat for
this species in the surrounding native forest adjoining the existing quarry.
However, no specific nesting areas or Dens were noted within the planned
operational area.
There is sufficient retained native forest surrounding the existing quarry, including
the planned landfill clearing areas to offer sufficient habitat for this species. It is
considered that the clearing of the landfill areas will not adversely impact on the
Quoll (spotted-tailed & eastern).
Tasmanian Devil - There is considered to be potential habitat for this species in
the surrounding native forest adjoining the existing quarry. However, no specific
nesting areas or Dens were noted within the planned operational area.
There is sufficient retained native forest surrounding the existing quarry, including
the planned Landfill clearing areas to offer sufficient habitat for this species. It is
considered that the clearing of the Landfill areas will not adversely impact on the
Tasmanian Devil.
grey goshawk – There is no suitable habitat for the Grey Goshawk which will be
impacted by the planned clearing operation. The Native forest within the clearing
area is predominantly E. obliqua or E. amygdalina regrowth forest with a scrubby
understorey with no predominance of Blackwood. No evidence of Grey Goshawk
was noted during the field visit.
19
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
masked owl - There is no suitable habitat for the Masked Owl which will be
impacted by the planned clearing operation. The Native forest within the clearing
area is predominantly E. obliqua or E. amygdalina regrowth forest, without
nesting hollows present. No evidence of Masked Owl was noted during the field
visit.
northwest velvet worm - There is no suitable habitat for the northwest velvet
worm. The planned clearing area is predominantly Dry heathy obliqua forest.
wedge-tailed eagle - There are two known nests within 850m to the North East of
the planned clearing. The impact of the planned operation to the known nests
was considered in a previous report conducted on the 26/9/2009. See the
attached report and diagrams in Appendix One. Note that the recommendations
within the report were reviewed by DPIPWE’s Bill Brown, who indicated that as
the operations were not line of sight, and given the ongoing and regular use of
this area for ongoing quarry activity (including the much closer quarry of
Johnstone), the landfill was unlikely to pose a threat to these eagle nests.
white bellied sea eagle - There is no suitable habitat for the White bellied sea
Eagle surrounding the planned clearing operation. This site is greater than 5kms
from the coastline or larger water bodies. The Native forest within the clearing
area and surrounding area is predominantly E. obliqua or E. amygdalina
regrowth forest. Much of the Native forest is sites unprotected from the prevailing
winds.
swift parrot - There is no suitable habitat for the Swift Parrot which will be
impacted by the planned clearing operation. The Native forest within the clearing
area is predominantly E. obliqua or E. amygdalina regrowth forest with a scrubby
understorey with no presence of E.ovata or E. viminalis. No evidence of swift
parrot was noted during the field visit.
20
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
C2 Weed and disease prevention: Due to this site being an existing operating quarry, the threat of the introduction
or spread of Phytophthora cinnamomi (PC) will not alter in relation to the planned
clearing operation.
It is expected that PC hygiene guidelines and management will be in place for
the Industrial site, for the use of existing machinery or the introduction of new
machinery onto the site to conduct the clearing operation.
As a minimum the Tasmanian Washdown guidelines should be applied to any
machinery involved with the planned clearing operations.
Treloar Transport will engage the Woodlands Group to advise on and develop a
weed management program for this site. This weed management program will be
developed before waste deliveries commence to the site.
C3 Rivers, creeks, wetlands and estuaries
There is one heavily impacted watercourse within the operational area. This
watercourse shows evidence of erosion due to the drainage of the previous
quarry works. Within the operational area this heavily impacted class 4 stream
does not exhibit a natural class 4 stream and flow. It is the headwater of the
Class 2/ 3 Goldie Creek. There will be no vegetation clearing within 200m of
Goldie Creek.
A settling pond will be re-established where the heavily impacted class 4 stream
enters a less disturbed and more natural flow pattern. Upstream of this pond, in
order to minimize soil erosion issues the watercourse will be barred, and
overland and downslope flows directed to designated rock lined drainage
channels.There will also be a settling pond installed on the western end of each
landfill bench. All settling ponds will have rock – lined discharge spillways.
21
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
It is expected that there would be an improvement to downstream water quality if
the above management methods are introduced.
Category A landfills are required to have surface water management
infrastructure with capacity to accommodate a 1 in 10 year reoccurrence interval
storm event. The diversion drains should be sized to carry all the runoff
generated in a 24hr period by such an event.
The size of water management infrastructure required was determined by the
Rational Method with the formula Q = 0.278CIA
Where
• C is the runoff coefficient, the average for bare packed rough / smooth soil
is 0.40, from Urban Erosion and Sediment Control, 1992, Department of
Conservation and Land Management
• I is the rainfall intensity in mm/hr, for 24 hours, 1 in 10 year event for
Forthside it is 3.57 mm/hr, obtained from the Bureau of Meteorology IFD
program • A is the catchment area in km2 , the catchment for the settling ponds has
been measured at 17,500m2 or 0.0175km2
Therefore Q = 417m3
This volume will be provided by five settling ponds as shown on Figure 2.
At the end of each fill bench there will be a small (60m3) pond, with the overflow
of these going to a larger pond (200m3). The clean water diversion has an
additional 80m3 pond.
It is proposed that surface water monitoring will be undertaken for the parameters
indicated in Table 4.5 of the Landfill Sustainability Guide. This monitoring will be
six – monthly for the first three years of operation, with the frequency and
22
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
parameters to be reviewed after that time depending on the results achieved.
The proposed location of the landfill is not below the local water table, as
evidenced by no standing water or permanently swampy ground, even after
periods of heavy rainfall. The water table level is likely to be below the minimum
recommended in the Landfill Sustainability Guide of 2m for an Inert Waste
Landfill.
Due to the inert nature of the materials being received by this landfill, and the
screening processes to be put in place, and the absence of hazardous or
dangerous substances to be stored on site, it is believed that there is negligible
risk of groundwater contamination and no need for groundwater monitoring.
C4 Significant areas and/or land features The Central Highlands Cainozoic Glacial Area is indicated as lying approx 400m
to the west of the planned clearing area.
Given the extent of the planned clearing area, and in relation to the existing
impact of current quarry operations, it is evaluated that there will be no impact to
the Central Highlands Cainozoic Glacial Area values.
C5 Coastal zone This is not applicable; the proposal is 8km from the coast
C6 Marine areas The proposal is not likely to impact upon sensitive marine or conservation areas,
due to its distance from coastal and streamside areas, and the inert nature of the
landfill materials
C7 Air emissions The emission of pollutants to air will be limited to dust and mobile equipment
23
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
exhaust. The limiting of materials deposited to inert waste, and the strict policing
of loads, will mean that no odours will be emitted.
Dust generation from the site will be limited by the sheltered nature of the landfill
site and the relatively moist climate of Forthside – an average of 965mm rainfall
per annum and 104 days of 1mm or greater rainfall. The access road past all
neighboring houses is sealed, and a site speed limit of 30kph will be enforced on
the Mining Lease thus limiting raised dust. The unsealed access road is
surrounded by forest vegetation, which will act as a dust filter.
In the unlikely event of weather conditions and traffic intensity resulting in raised
dust being an issue, Treloar Transport has a number of water trucks that can be
used to suppress dust on an “as required” basis.
Mobile plant exhaust emissions will be controlled by maintaining plant exhaust
systems to the manufacturer’s recommendations.
C8 Liquid effluent
The proposal does not result in the discharge of liquids (including to sewer) –
except storm water, which is discussed in C3.
C9 Solid Wastes C9.1 Litter The activity is an inert waste landfill, with putrescible waste prohibited, and all
loads screened before unloading. Treloar Transport has successfully run an inert
waste landfill at Devonport for many years without litter being an issue. The site
will also be routinely tidied with housekeeping a major priority.
However, if litter is inadvertently dumped on site, the landfill location is bordered

by quarry faces on two sides. The other two sides of the landfill are bordered by
vegetation which will act as a litter trap. In the unlikely event of litter being a
problem, a chain mesh fence will be constructed bordering the southern property
boundary to also trap litter.
Treloar Transport commits to collecting any litter from the site and removing it to
a suitable licenced landfill.
C9.2 General Waste Whilst the site is manned a portable chemical toilet will be provided. General
waste such as food scraps will be taken off site for correct disposal. Major
equipment maintenance will not be undertaken on site – if major repairs are
required to any mobile plant or trucks they will be transported to Treloar
Transport’s maintenance depot at Sheffield. Any waste generated from routine
maintenance will also be removed off site.
C10 Noise emissions
There will be only two noise sources on site. A wheel loader will be used
intermittently to push off dumped loads of incoming material and to compact
dumped material. It will also be used to load out material for recycling. This
machine will not be in constant operation, experience at the Devonport inert
waste landfill indicates that use for 5 to 6 hours a day would be the maximum
duty.
The second noise source will be trucks delivering, and to a lesser extent
removing, material from site. These will also be intermittent noise sources.
There are no residences within direct line of site of the proposed landfill. Located
towards the bottom of a natural “amphitheatre”, the site is ideally located to
minimize noise emissions. 25
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
C11 Transport impacts
The budgeted delivery rate of 10,000m3 per annum is equivalent to 1,000 inwards
vehicle movements of 10m3 trucks, per annum. (An assumed average based on
Hillcrest Road experience of delivery vehicles ranging from utilities, trailers, up to
trucks and dogs and semitrailers.)
Current vehicle movements are an approximate maximum of 500 per annum
(5,000 m3 of extracted material averaging 10m3 loads).
The additional vehicle movements correspond to an average of one vehicle
inwards for every three hours the landfill is potentially open – considering the
existing extractive activity, given that some trucks will both deliver inert waste and
depart with a subbase load, vehicle movements (expressed in terms of a truck on
site equals two movements), will be one for each hour the site is open.
Based on experience at the Hillcrest Road landfill, the maximum anticipated
vehicle movements would be 8 per hour for short periods.
The other operating quarry in the locality is run by Mark Johnstone. It is a Level 1
quarry, the entrance to which is 620m to the north of the Stubbs quarry entrance.
This private road enters Forthside Road at a T junction. Both companies’ trucks
are equipped with UHF radios, and will be in communication whilst on Forthside
Road as a means of improving road safety.
Figure Two is the traffic management plan.
Treloar Transport drivers will be instructed to limit their speed to 60 kph on that
section of Forthside Road south of the Bellamy Road junction.
Vehicles exiting the landfill and quarry access roads will be required to “Give
Way” to any other traffic. This direction will be supported by standard road

signage. Forthside Road in this locality is very low traffic flow – it is a “No
Through Road, with only one residence past the accesses to the Mining Lease.
The accesses to the quarry will be graveled and maintained, to prevent the
carryover of mud onto public roads.
C12 Other off-site impacts Sensitive uses such as schools and retirement homes are greater than 4km
distant. The only other potential off-site impact is visual. However, the landfill
activity will not be visible from any houses or public roads. The quarry operation
is only slightly visible as a distant view (3.25km) from the Forth – Sprent Road,
and this visibility will be reduced by rehabilitation plantings to be undertaken at
the western end of the quarry.
C13 Dangerous goods and chemicals The proposal will not involve the storage of dangerous goods or hazardous
substances. Fuels and oils will not be stored on site overnight, but will be brought
to site on an as required basis. Waste oil and used filters generated by vehicle
servicing will be removed from site on the service vehicle. There will an oil spill kit
on site to deal with minor oil spills that might arise, and the fuel truck will also
carry a spill kit. Refueling will be undertaken in the quarry rather than on the
landfill in order to maximize the distance from the watercourse.
C14 Site contamination
C14.1 Past history of site The site has no past history of activities that may have caused soil or
groundwater contamination. It is believed the 1970’s was the peak period for
27
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
extraction from the site with material being used for the Devonport Airport
redevelopment. There is no evidence of previous structures or storage tanks on
site.
C14.2 Site hygiene Contamination of the site will be prevented by avoiding accepting materials
infested with designated weeds or from areas of P. cinnamoni infection. Treloar
Transport is aware of the significance of having P. cinnamoni - free quarries, and
wishes to protect this status.
C15 Resource Issues There will be no sterilization of stone resources by this proposal. The quarry is
being worked from the top down. As the deposit is on steep terrain, and the
lease is narrow, it is not possible to extract all of the resource from the crest of
the ridge to the toe of the deposit leaving a slope angle that would ensure long
term stability. This is shown on Figure Four.
The toe of the existing face (where the landfill will be developed) will not further
worked for quarry extraction, except for the removal of loose and eroded material
(included in the Level One quarry 5,000m3 yearly extraction limit), to enable the
landfill earthworks to effectively “key into” the existing terrain.
C16 Cultural heritage. C16.1 Aboriginal heritage The guidelines for the Environmental Effects Report noted that Aboriginal
Heritage Tasmania (AHT) has consulted the Tasmanian Aboriginal Site Index
database and AHT records, which indicated no previously recorded Aboriginal
heritage sites within or nearby the proposed impact area. The site has been
heavily disturbed by previous quarrying activities. Although limited amounts of
28
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
vegetation will be cleared for the landfill footprint (<1Ha), an examination of the
area shows extensive previous excavation earthworks. The footprint of the quarry
will not be expanded beyond what it is now. Due to the level of disturbance it is
considered unnecessary to conduct further field surveys for Aboriginal heritage.
C16.2 Sites of high public interest. The proposal is not located within or adjacent to any sites of scenic, tourism or
public interest. The nearest site of public interest is the Tasmanian Arboretum,
which is 2km to the east, with the Mining Lease not being visible from this site.
C17 Rehabilitation C17.1 Final landform Historical use of the site has resulted in the current heavily disturbed, steep
terrain profile. Treloar Transport intends to work the quarry component of the
operation in a manner designed to terrace the existing steep slopes, minimizing
erosion potential, and ensuring long term stability by reducing the overall slope
angle.
The inert waste landfill will be at the toe of the quarry, and will conform with this
rehabilitation principle, consisting of a series of terraces, 7m wide, backsloped at
1:20 into the hill side (to assist in slowing waterflow) at 5m vertical intervals, with
the slopes between at 1v:3H. This results in a final overall slope angle of 15o,
which is comparable to the existing natural terrain. It will be much flatter than the
existing disturbed quarry which has slopes greater than 45o in some sections.
This relatively flat angle, plus water management measures directing flows to
designated rock lined channels, will ensure geotechnical stability.
The footprint of the landfill after ten years of operation will be 6000m3.
29
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
Final land uses are limited by the steepness of the site and the surrounding
terrain, with the most appropriate use being wildlife habitat.
Completed landfill sections will be covered with 0.8m of selected clean fill and
topsoil, as per the Landfill Sustainability Guidelines for inert waste landfill. This
material will be sourced from delivered materials.
As the landfill will commence on the western extent of the bottom bench,
progressive rehabilitation will commence as soon as the tipping face has
retreated sufficiently to enable a sufficient area of landfill to be reshaped. It is
estimated approximately 2,000 m2 of landfill will be rehabilated on a yearly
basis. Advice will be sought from Tas Land and Forest and Forestry Tasmania on
suitable local species to be spot planted, as well as a suitable cover crop to
quickly develop a suitable erosion preventing ground cover.
C17.2 Landfill aftercare monitoring Aftercare monitoring will consist of:
• Maintaining the final landform design until an acceptable level of stability is
reached – i.e. adding material to remedy slumps, repairing erosion,
maintaining drains and settling ponds
• Maintaining vegetation – i.e. replanting losses, weed control.
• Monitoring of surface run – off in settling ponds.
This aftercare will continue until the Regulator, in discussion with Treloar
Transport, agrees that a suitable level of stability and rehabilitation standard has
been reached.
30
Treloar Transport Pty Ltd Forthside Solid Inert Landfill EER September 2010 Ver. 2
C18 Sustainability Inert waste is a necessary byproduct of all development, whether civil, residential
retail or transportation infrastructure. This proposal represents best practice in
dealing with this waste – disposal of the material in a previously heavily disturbed
area, providing an opportunity to rehabilitate this disturbance that would not
otherwise occur.
The proposal also minimizes the transportation distance required to dispose of
this material, being close to the centre of Treloar Transport’s operations in the
Kentish and Devonport Municipalities. If we assume half of the generated
material would have to travel 10km further to Ulverstone for disposal, assuming
this is 500 x 10m3 loads, with an average truck fuel economy of 2 km/litre this
results in a saving of 27 tonnes of CO2 equivalent per annum.
The opportunities for reuse of material at this civil – contractor operated site
results in 3,000 tonnes of material being reused on other projects – if we assume
Treloar Transport would have to manufacture this material, at an average CO2
equivalent of 2.3 kg/ tonne (actual figures derived from diesel and electricity
consumption at the Shackley Hill quarry), this results in a further saving of 7
tonnes of CO2 equivalent per annum.
Further, up to one third of trucks delivering material to the landfill will collect a
replacement load of quarry material. If these trucks had to travel to the Shackley
Hill Quarry for a replacement load, the extra 10,000km travelled per annum
would result in the generation of a further 27 tonnes of CO2 equivalent per
annum.

Treloars Stubbs Road Quarry clearing Report by Joe Hawkes – Tas Land & Forests
Reviewed as of the 1st of July, 2010
Scope of Report: To investigate the requirements under the Forest Practices Act by Treloars Transport in relation to planned clearing operations adjacent the existing quarry. To evaluate the potential environmental effects under Part C of the Environmental Effects and Report Guidelines required by EPA Tasmania (Environmental Protection Authority) Treloars Transport is planning to clear a small section of Native Forest adjoining the boundaries of an existing Gravel pit area for solid inert landfill. There are no requirements under the Forest Practices Act. A Forest Practices Plan is not required as this operation falls under Mining operations. Description of Soils and underlying rock types: The geology substrate for this area is Lts – Precambrian – Forth metamorphics - Dominantly Quartzite. Soil description as moderately well drained soils formed from Precambrian quartzite. A dark grey sapric sandy loam overlies a greyish brown loamy sand and a massive, bleached sand densipan. There are abundant quartzite stones throughout the profile. Erodibility is rated as Moderate to High, Considerations: Investigation was conducted through the standard Forest Practices processes. A number of reports and maps were generated to evaluate any potential values that may be impacted by the planned operation. Natural Values Atlas, Conserve Map and report, Geology, RFA communities, Google Earth, Threatened Fauna mapping.
Flora: The 0.65ha area is keyed out as Dry-hOB - Heathy E. Obliqua forest – Dry E.Obliqua forest which also does not require further protection under the RFA or Forest Practices process. Therefore it was determined that this floristic community was not considered a community requiring further protection through the Regional Forest Agreement or as a Threatened community through the Forest Practices Act process. There are no known localities of Threatened Flora Species within the vicinity of the planned clearing operations. (as per Conserve report) The Common hemp-bush was not noted in field visits across the site. Fauna: There are no known localities of Threatened Species within the vicinity of the planned clearing operations. (as per Conserve report) There was no identified potential habitat for threatened species that will be impacted by the planned clearing operations by Treloars Transport. The considered Threatened species are as per the Kindred Threatened Fauna Manual (map no. 4243) under the Forest Practices Authority – See attached. There are no nesting or den sites located within the planned clearing area and no Threatened Species will be impacted by the planned landfill clearing areas. Management prescriptions to maintain downstream water quality are described below in further considerations. The full list of potential Fauna Threatened Species that may occur within this region are:- giant freshwater crayfish – There are no streams within the planned clearing areas, which have suitable habitat for the Giant freshwater crayfish. There are heavily modified watercourses related to drainage of the previous quarry works, however, these watercourses do not contain suitable or potential habitat for the GFC. australian grayling - There are no streams within the planned clearing areas, which have suitable habitat for the Australian grayling. For all aquatic Threatened Fauna species it is considered that there is not suitable habitat that will be impacted by the planned clearing areas. It is felt that it is important to maintain downstream water quality. It is felt that specific management is required to maintain downstream water quality. hydrobiid snail - there are no streams within the planned clearing areas, which have suitable habitat for the Hydrobiid snail, the hydrobiid snail is not known within this stream catchment.
eastern barred bandicoot – There is considered to be potential habitat for this species in the surrounding native forest adjoining the existing quarry, however, no specific nesting areas were noted, nor was it optimum habitat i.e. grasslands, tussock, grassy paddocks, reeds or heath within the planned operational area. There is sufficient retained native forest surrounding the existing quarry, including the planned Landfill clearing areas to offer sufficient habitat for this species. It is considered that the clearing of the Landfill areas will not adversely impact on the Eastern barred bandicoot. quoll (spotted-tailed & eastern) - There is considered to be potential habitat for this species in the surrounding native forest adjoining the existing quarry, however, no specific nesting areas or Dens were noted, within the planned operational area. There is sufficient retained native forest surrounding the existing quarry, including the planned Landfill clearing areas to offer sufficient habitat for this species. It is considered that the clearing of the Landfill areas will not adversely impact on the Quoll (spotted-tailed & eastern). Tasmanian Devil - There is considered to be potential habitat for this species in the surrounding native forest adjoining the existing quarry, however, no specific nesting areas or Dens were noted, within the planned operational area. There is sufficient retained native forest surrounding the existing quarry, including the planned Landfill clearing areas to offer sufficient habitat for this species. It is considered that the clearing of the Landfill areas will not adversely impact on the Tasmanian Devil. grey goshawk – There is no suitable habitat for the Grey Goshawk which will be impacted by the planned clearing operation. The Native forest within the clearing area is predominantly E. obliqua or E. amygdalina regrowth forest with a scrubby understorey with no predominance of Blackwood. No evidence of Grey Goshawk was noted during the field visit. masked owl - There is no suitable habitat for the Masked Owl which will be impacted by the planned clearing operation. The Native forest within the clearing area is predominantly E. obliqua or E. amygdalina regrowth forest, without nesting hollows present. No evidence of Masked Owl was noted during the field visit. northwest velvet worm - There is no suitable habitat for the northwest velvet worm. The planned clearing area is predominantly Dry heathy obliqua forest. wedge-tailed eagle - There are two known nests within 850m to the North East of the planned clearing.The impact of the planned operation to the known nests was considered in a previous report conducted on the 26/9/2009. See attached report. Please note that the recommendations within the report were approved by Bill Brown, as the operations were not line of sight and given the ongoing and regular use of this area for ongoing quarry activity. white bellied sea eagle - There is no suitable habitat for the White bellied sea Eagle surrounding the planned clearing operation. This site is greater than 5kms from the coastline or larger water bodies. The Native forest within the clearing area and surrounding area is predominantly E. obliqua or E. amygdalina regrowth forest. Much of the Native forest is unprotected sites from the prevailing winds. swift parrot - There is no suitable habitat for the Swift Parrot which will be impacted by the planned clearing operation. The Native forest within the clearing area is predominantly E. obliqua or E. amygdalina regrowth forest with a scrubby understorey with no presence of E.ovata or E. viminalis. No evidence of swift parrot was noted during the field visit.
Phytophthora cinnamomi: Due to this site being an existing operating quarry, the threat of the introduction or spread of Phytophthora cinnamomi will not alter in relation to the planned clearing operation. It is expected that PC hygiene guidelines and management will be in place for the Industrial site, for the use of existing machinery or the introduction of new machinery onto the site to conduct the clearing operation. As a minimum the Tamanian Washdown guidelines should be applied to any machinery involved with the planned clearing operations. (See attached additional documentation in regard to Phytophthora cinnamomi hygiene guidelines and management.) Water Quality and Drainage management: - Rivers, creeks, wetlands, estuaries There is one heavily impacted watercourse within the operational area. The class 4 stream is the headwater of the Class 2/ 3 – Goldie Creek. This watercourse has been heavily impacted due to the drainage of the previous quarry works. Within the operational area the heavily impacted class 4 stream does not exhibit a natural class 4 stream and flow. There is evidence of erosion occurring along this watercourse, and adjoining watercourses due to the previous Quarry operations. There is potential to consider establishment of settling ponds along the course of the heavily impacted class 4 stream, to help maintain storm water flows, erosion and maintain water quality. Further drainage measures may be considered necessary, e.g. barring or gripping steeper sections, tacks etc., to minimise soil erosion issues. It is expected that there would be an improvement to down stream water quality if the above management objectives are met. i.e. drainage will be maintained. Central Highlands Cainozoic Glacial area: The Central Highlands Cainozoic Glacial area is indicated as lying approx 400m to the west of the planned clearing area. The extent of the planned clearing projects, and in relation to the existing impact of current quarry operations, it is evaluated that there will be no impact to the Central Highlands Cainozoic Glacial area values.
Summary: There are no requirements under the Forest Practices Act. A Forest Practices Plan is not required as this operation falls under Mining operations. Further considerations: That Phytophthora cinnamomi hygiene management measures are considered for the site. Effective drainage measures are considered for the watercourses to maintain and improve downstream water quality. Joe Hawkes Forest Consultant Tas Land & Forests 0438 248 855

Duration (mins): 1 hour
Nest Description: (Write a description of what was observed e.g. indicate quality, nest composition, colour, shape, size, condition.)
…Quality and condition of nest looked good, brown sticks that looked relatively fresh, shape of nest rounded from view point, looked small in size, majority of nest was brown in colour. No white wash was noted around nest or limbs, or on main trunk, base of tree not visual away from nest. One side of the nest was rounded however, possibly looking like this side of the nest hadn’t been built up, possibly keeping the nest small in size, it did not appear that there was any specific collapse of nest. It was difficult to determine the width of nest with time availability. There did not appear to be any fines particularly, the composition appeared to have larger and coarse size branches.
Were any of these observed on the nest? (tick box if present
Green Leaves Fresh (brown) sticks √ White wash (droppings) Prey remains Bird on nest or nearby (note age if possible)
Bird Activity Observed: (Write a description of what was observed e.g. Two birds soaring over the nest, bird carrying sticks)
