Shaw Contracting (Aust) Pty Ltd through a fully owned subsidiary, Midland Quarries Pty Ltd is looking to open and operate a rock quarry (Category 3, Level 2 Mining Lease) to meet these needs.
Category 3 Construction Minerals – stone, clay and sand
Level 2 Extraction of more than 1,000m3 (Up to 100,000 m3/250,000 tonnes pa)
The business will produce quarry products to specifications of the Department of State Growth G6 & R40. The quarry products will involve drilling, blasting and crushing to make the following materials:
Road Pavement Materials (Gravel – sub base 2, sub base 1 & base A)
Sealing aggregates
Concrete aggregates
Rock armour
Rock spawls
Drainage rock and pipe bedding
It is proposed that by June 2016 the quarry could be potentially producing 100,000 m3 per annum to supply the Midland Highway Upgrade. A quarry plan will be developed for the site that will cover quarry staging and progressive rehabilitation.
Page 8 of 37
2.1.1 Proposed Activity
Midlands Quarries is proposing to develop a dolerite rock quarry to produce quarry products for infrastructure projects. Attached is a schematic showing the quarry process and how products are made. Prior to the crushing process outlined drilling and blasting of the resources is required, this will be completed with a blast pattern of 3.5m x3.5m, 12 metres deep to produce around 8,400m3 and will be completed by subcontractors.
The equipment to be used will be as follows
Machine Type No. Ownership
Wheel Loader 980 2 MQ
Excavator 30 tonne 1 MQ
Articulated 40 tonne dump truck 1 MQ
Water cart 1 MQ
Mobile drill rig 1 Subcontract
Mobile crusher 1 MQ
Truck and trailers up to 10 Subcontract
The materials from the first blast and crush will be used to form the site infrastructure of hardstands and access roads as well as prove up the quality of the material to Department of State Growth material specifications.
Once this is completed the quarry will be developed as per stage 1 to RL 278 from the east to the west as per appendix 1.5. Once this is completed stage 2 will be commenced. All drainage will be to the southern end of the site where a sediment pond will be constructed to catch all run off from the quarry.
All works will be completed with excavators and wheel loaders with mobile crushers. It is proposed to use mobile crushers for the entire operation due to the flexibility gained reflecting potential demand.
All materials once processed will be delivered to clients using on road truck and trailers.
Rehabilitation will be completed at the end of stage 2.

Short Term Targets
Submission of Notice of Intent to EPA October 2014
EER submission to EPA June 2015
Application for a Mining Lease September 2015
EPA and MRT Approvals September 2015
Northern Midland Council Planning Approval October 2015
Page 11 of 37
Long Term Targets
To have initial infrastructure works by October 2015 including the acquisition of a second hand mobile crushing plant
To be producing 100,000 m3 per annum of material by June 2016
A detailed program has been included in Appendix .1.11
2.1.4 Operating Hours
The proposed operating hours for the quarry are
Monday to Saturday 6am to 6pm
The operating hours nomination are based upon the following
- Location of nearest residence being 3.5 kilometres away
- Rural zoning
2.1.5 Production Capacity
It is proposed that the quarry would have the capacity to produce up to 2,500 m3 per week and is likely to operate for 10 months per year depending on demand. Demand will be at its highest over the Spring to Autumn period with reductions in demand during the winter months.
Capacity of the quarry could be doubled to 5,000m3 per week if demand required, this would only be completed during peak periods of demand and would be unlikely to affect the overall yearly output. A second mobile crusher would be required to complete this. Winter months will be used to complete proactive maintenance.
The current overall life production volumes for the quarry are detailed below
Stage Quarry Footprint Extracted Volume Volume Processed Period
1 1.1Ha 93,000m3 177,000m3 2 yrs
2 3.3Ha 274,300m3 521,000m3 5 yrs
2.1.6 Mining Plan
Quarry staging plans and sections have been completed and are attached in Appendix 1.5.
Page 12 of 37
2.2 PROPOSAL AREA
2.2.1 General
The area is sparsely vegetated with minimal topsoil and subsoil present due to the prevalent Jurassic dolerite at the surface. Trees are on the site are no greater than 3.0 metres with the exception of a few eucalyptus trees. A Flora and Fauna Report has been completed which further elaborates on the details of the area.
The southern and western boundaries have a creek approximately 150 metres and 300 metres respectively downstream. The creeks are dry during the summer period and flow in winter.
The southern and western boundaries are adjacent to grazing pasture owned by Quorn Hall which is actively farmed, the proposed lease area is not farmed due to the prevalent rock at the surface not being suitable.
2.2.2 Local Climate
The local area has a temperate inland climate, with maximum daytime temperatures ranging from 25 degrees in February to 11degrees in July and minimum averages of 8.8 to 0 degrees. Katabatic air drainage from the fringing tiers can produce cold winds on the plain in all seasons and frosts are frequent from May through to October. In common with much of eastern Tasmania the area is relatively dry, receiving approximately 560mm rainfall distributed evenly throughout the year.
Temperature
The maximum mean temperature for the area is 17.8 degrees with February being the hottest with 24.6 and July being the coldest with 11.1 degrees. The minimum mean temperature average 14.7 degrees with February the hottest with 8.8 degrees and July the coldest with 0.1 degrees.
Rainfall
The annual rainfall is 560mm per year with most months averaging between 45 to 55m with the exception of January and February which is between 25 to 35mm
Wind
Wind is predominantly (50%) from the north to north west where the highest wind speeds are recorded being up to 40km/hr and greater. Wind from a southerly direction can be up to 40km/hr but accounts for 15% of total time.
The quarry is located to the east of Campbelltown, winds with an easterly component do not exceed 20 km/hr and occur less than 10%of the time.
Page 13 of 37
2.2.3 Current and Historical Use of Site
The proposed location is on farmland that has minimal agricultural use due to the presence of rock at the surface and minimal growing medium suitable for farming.
An Aboriginal Assessment Report has been completed showing little evidence of activity in the area
A previous quarry has been identified on the lease which was used by the Tasmanian Government around Word War II where local airstrips where constructed using material from the quarry. The sites are clearly shown on the lease area and will not be used in the proposed operation, they will be located in the buffer zone.
The nearest residence is Quorn Hall being 3.0 kilometres to the west of the site along the Lake Leake Road, Campbell town is located 6.0 kilometres away from the site.
A compensation agreement has been drawn up between Midland Quarries and Quorn Hall for the project.
2.2.4 Land Use/Zoning
The land is currently used as farming and is zoned ‘Rural Living’ under the Northern Midlands Council Interim Planning Scheme 2013.
2.2.5 Soils and Underlying Rock Types
The quarry is located on Jurassic Dolerite hills to the east of gently north-sloping sedimentary plain of Late Carboniferous-Triassic age where Campbell Town is located.
The resident soils, which are typologically chromsols of the Bloom field complex, are skeletal on the ridgetop and higher flanks where dolerite sheet rock subcrops, with thin sandy materials forming the lower slopes and terraces derived from Aeolian remobilisation of plain sediments. Organic soils are thin to absent and the area has been heavily grazed with deflation resulting in exposure of angular float and underlying dolerite sheet rock.

The following maps and site plans are included in the appendices
Appendix 1.1 General Location Map
Appendix 1.2 Quarry Layout Plan
Appendix 1.3 Stormwater Management Plan
Appendix 1.4 Visual Screening Plan
Appendix 1.5 Quarry Staging Plan and sections
2.4 RATIONALE AND ALTERNATIVES
With the announcement of the $500M Midland Highway Upgrade to be completed from 2015 to 2025, there will be a significant demand for quality quarry products to the Department of State Growth’s road and bridge specifications in the Midland area. In addition to the Midland Highway upgrade there will be other key markets that the quarry will target
Local Councils and Farmers
Tas Water
Major infrastructure suppliers
Shaw Contracting (Aust) Pty Ltd through a fully owned subsidiary, Midland Quarries Pty Ltd is looking to open and operate a rock quarry (Category 3, Level 2 Mining Lease) to meet these needs.
Category 3 Construction Minerals – stone, clay and sand
Level 2 Extraction of more than 1,000m3 (Up to 100,000 m3)
The business will produce quarry products to specifications of the Department of State Growth G6 & R40. The quarry products will involve drilling, blasting and crushing to make the following materials:
Road Pavement Materials (Gravel – sub base 2, sub base 1 & base A)
Sealing aggregates
Concrete aggregates
Rock armour
Drainage rock and pipe bedding
It is proposed that by June 2016 the quarry could be potentially producing 100,000 m3 per annum to supply the Midland Highway Upgrade. A quarry plan will be developed for the site that will cover quarry staging and progressive rehabilitation.
Shaw has investigated other potential sites for a quarry to meet the same supply requirements, however the location to the Midlands Highway, the low risk of environmental and heritages issues, close distance to Lake Leake Highway and no traffic issues, no nearby residents and co-operation with the landowner has deemed this to be the best site.
Page 15 of 37
2.5 PLANNING INFORMATION
An application for permit under Land Use Planning and Approvals Act 1993 (LUPPA) is required for this development. The following requirements have been addressed as per the Northern Midlands Council Interim Planning Scheme 2013
Clause 26.3 (P3, P4 & P5)
P3 – The proposed area does not support farming or agricultural use due to the surface rock present. The proposed area is not currently farmed and will not be in the future and has little to no agricultural value.
P4 – Emissions from the activity are considered low (refer 3.5 and 3.13). Effects from traffic are considered to be low as per the Traffic Impact Assessment completed, refer Appendix 1.9. All recommendations from the TIA have been adopted Section 5 – Management Commitments’.
P5 – Visual appearance has been addressed with suitable screening walls nominated around the proposed hardstand areas as well as site line being completed as per Appendix 1.4.
Code E4 – Road Asset Code
Lake Leake Road is considered to be a Category 1 Trunk Road and as such a Traffic Impact Assessment has been completed for the activity, this is located in Appendix 1.9. All recommendations from the TIA have been adopted Section 5 – Management Commitments’.
Code E6 – Car Parking and Sustainable Transport Code
As per Table E.6.1, MQ will provide three (3) car spaces to meet the requirements of 1 space per 2 employees. MQ envisages that there will be no more than six (6) employees on site. There has been no allowance for disabled parking, bicycle or pedestrian access given the nature of the activity.
Code E7 – Scenic Management Code
This section of the planning scheme is not applicable to the proposed activity as it is located more than 200 metres from the Lake Leake Highway frontage and is not included in the local scenic management areas defined in Table E7.1
Code E8 – Biodiversity Code
A Flora and Fauna report has been completed and addresses all the requirement of the planning scheme, please refer Appendix 1.6,
Code E9 – Water Quality Code
This code is not relevant as the proposed activity is located 200 metres away from a wetlands or watercourse

3.0 POTENTIAL ENVIRONMENTAL EFFECTS
3.1 FLORA AND FAUNA
A flora and fauna assessment has been completed by Stephen Casey Ecological Consulting. The survey found that there were two vegetation communities in the proposed development area being Bursaria-Acacia woodland and Lowland Grassland Complex with neither of these communities considered threatened under State or Federal legislation.
A number of threatened fauna species had the potential to utilise the site due to presence of suitable habitat being the Tasmanian Devil (Sarcophilus harrisii), the spotted-tail quoll (Dasyurus maculatus maculatus), the eastern barred bandicoot (Perameles gunnii gunnii) and the tussock skink (Pseudemoia pagenstecheri). The habitat on site is marginal for the quoll and devil, however they may occasionally use the site. Some habitat for the bandicoot and skink may be lost however the impact on these species will be minimal.
As the skinks are listed as vulnerable under the Tasmanian Threatened Species Protection Act 1995, Midlands Quarries will develop a Vegetation & Weed Management Plan to assist in maintaining and improving their habitat. This Plan will be reviewed by DPIPWE Conservation Assessment Section. An additional commitment to compete a survey for skinks in blast areas will also be provided.
If tussock skinks are located in the surveys they will be relocated to a suitable habitat outside the work area by a suitably qualified person.
There are a number of weed species present on the site, these will need to be managed on site. A commitment to implement the DPIPWE Washdown Guidelines for Weed and Disease Control – Edition 1 is made in Part D of this EER. This will also be managed under the Vegetation & Weed Management Plan.
All recommendations stated in the report have been included in section 4 ‘Commitments’ of this EER. The report is included in Appendix 1.6.
3.2 AQUATIC ENVIRONMENT AND STORMWATER
The proposed activity will have no impact on a creek river or wetland within 200 metres of the lease boundary. The closest waterway to the lease is Keach Creek, run off will travel overland via highly modified drains on agricultural land. No native species and fauna habitat were found.
Sediment ponds have been designed to be installed at the base of the access road and adjacent to the quarry floor as demonstrated in Appendix 1.3, these will have the capacity to take a 1:20 year rain event over the adjacent catchment areas.
It is not envisaged that the proposed activity will have any effect on groundwater. The quarry benches are designed to be free draining, the only areas where there will be standing water will be the sediment ponds.
Page 17 of 37
3.3 SIGNIFICANT AREAS
The proposal is not located within or adjacent to any existing reserved areas.
3.4 MARINE AREAS
There will be no impact on marine areas due to the location being inland Tasmania
1.5 AIR EMISSIONS
Air emissions will fall into 2 major categories for the site being dust generation and emissions from mobile plant, these are identified along the control measures. A key factor in managing air emissions on the site is that all residence and the town of Campbell Town are to the west of the quarry site with the predominant winds coming from the north to north west. The areas to the east and south east of the quarry are predominantly farming or bush with no nearby residences
Dust
Dust will be a key environmental aspect of the site and operation that will need to be managed, key activities that will generate dust on site will be
Overburden removal
Drilling and blasting
Crushing and screening
Cartage of crushed materials around site
Cartage of materials of site
Dust will be managed on the site as follows
Overburden removal on the site will be minimal due to the minimal presence of topsoil and dolerite sheet rock present at the surface. As the amount will be minimal the amount of dust to be generated from the activity will be low, in the event that overburden is removed a 10,000 litre water cart will be used in the operation.
Drilling and blasting will generate minimal dust due to the massive nature of the dolerite rock on site and minimal clay in the rock body. The main cause of dust will be the crushing operation. The adjacent Lake Leake Highway is 700 metres away with the nearest residence being 3,500 metres way. The Quarry Code of practice recommends that the nearest sensitive use is 750 metres for crushing and 1,000 metres for blasting.
The crushing, screening and stockpiling operation has the potential to cause dust, the following key control measures will be used to minimise dust
Page 18 of 37
- Internal roads and hardstands will be maintained to a high standard to prevent a loose surface from forming generating dust
- Drop distances from conveyors to stockpiles will kept to a minimum
- Drop distances from loaders to trucks will be kept to a minimum
- On windy days a 10,000 litre water cart will be used to water internal roads and stockpiles
- Speed limits will apply to all plant on internal roads
Shaw proposes to seal the main access road from Lake Leake Road to the stockpile area with a bituminous seal with 12 months of the quarry opening. The sealing of the road will eliminate dust from cartage of material from the site, until this is completed, Shaw will run a 10,000 litre water cart on site during carting activities.
Other emissions from the site will be carbon dioxide emissions from diesel powered plant, the following plant will be used on site
- 2 x 40 tonne loaders
- 1 x 33 tonne excavator
- 1 x 40 tonne articulated dump truck
- 1 x 10,000 litre water cart
- 1 x Jaw crusher
- 1 x Cone Crusher
- 1 x Vertical Shaft Impact Crusher
- Various conveyors and screens
3.6 LIQUID EFFLUENT
Contaminated process water and run off water will carry rock, sand and silt sediments with little to no clay content. The nominated stormwater retention pond and silt traps will adequately address the situation as per the attached plans
Effluent from human sanitary systems will be managed as follows, the site office and personnel facilities will be serviced with a 10,000 litre pump out tank, and this will be disposed off at the Taswater facility at Campbell Town as required. Midland Quarries will enter a contract with Veolia or other suitably qualified company to do so.
Page 19 of 37
3.7 SOLID WASTES
Solid wastes that are produced during the quarrying operation will be minimal and limited to the following
General Site Rubbish - -managed by enclosed skip bins through a subcontractor
Workshop waste – managed by enclosed skip bins through a licensed operator
The proposed subcontractor will have a contract with Midlands Quarries and will dispose of material at licensed landfills or recycling centres.
Recycling of any waste materials will be completed with the use of nominated waste bins.
3.8 NOISE AND VIBRATION
Midland Quarries recognise that the activities nominated will generate noise and vibration. Midlands Quarries has chosen this site due to its location from noise sensitive premises with the nearest residence being 3,5000 metres away.
Midland Quarries proposes to complete the following upon commencement of the site
- Background ambient noise levels recorded at the closest house for one week
- Develop a Blast Management Plan addressing noise and vibration
- Noise and vibration are monitored during blasting and recorded
- Noise and vibration are to be below the following limits for all blasting
1. Air blast overpressure 115dB (Lin peak)
2. Ground Vibration 5mm/sec (Peak particle velocity)
3.9 TRANSPORT IMPACTS
The proposed activity will increase traffic movements on the Lake Leake Highway by the following
Light vehicles 6 vehicles per day (6:00am and 6:00pm)
Heavy Vehicles 30 truck and trailers per day (6:30am to 5:00pm)
All traffic movements will be heading west along Lake Leake Highway from the proposed site towards Campbell Town.
A Traffic Impact Assessment has been completed for the project and is attached in the Appendix 1.9.
Page 20 of 37
3.10 OTHER OFF-SITE IMPACTS
As the site is located 3,500 metres from the nearest residence and 6.0 kilometres from Campbell Town there is minimal chance of other off-site impacts. Increased traffic movement is the most likely potential and this is addressed in the Traffic Impact Assessment
3.11 HAZARDOUS SUBSTANCES
The following hazardous substances will be associated with the proposed activity and will be managed as detailed below
Explosives – not to be stored on site and will be brought to site through an accredited blasting contractor meeting all Australian Standards for carting and storing
Hydrocarbons will be stored on site away from traffic paths and will be bunded as per Australian Standards. The volume of diesel to be held will be 10,000 litres. Fuel spill kits will be on site for any unlikely spill. The presence of machinery on site will also allow them to be used to contain a spill if one was to occur.
Herbicides for weed control will be brought to site as required and will be stored, transported and handled by appropriately trained workers.
Shaw will have an Emergency Response Plan as part of the site Project Management Plan (PMP) which will cover the requirements of a major fuel spill.
3.12 SITE CONTAMINATION (HISTORICAL)
The site has no historical information on site contamination, previous uses have included farming and quarrying. The quarrying was a small volume being less than 30,000m3. There is some evidence of road side litter and dumping, however due to the dolerite sheet rock present on site the probability of buried contaminated material is deemed to be low
Page 21 of 37
3.13 CLIMATE CHANGE
The premise of the proposal is to reduce overall energy consumption by supplying quarry products to the Midlands Highway. One of the main energy uses in the operation is delivery of materials from the quarry to the road construction site. Currently the existing registered quarries to supply material are located at Launceston and Hobart, the cartage distances and fuel consumption will be halved for road projects on the Midlands Highway by supplying materials from this new proposal.
Energy consumption will be reduced on site by carrying out all works efficiently as possible. Particular attention will be paid to the drilling and blasting on the site as efficient blasting of the rock can reduce crushing times and effort significantly reducing fuel consumption.
Midlands Quarries will use new equipment in the production of the quarry which will have efficient energy consumption and low greenhouse gas emissions.
The proposed activity has been assessed against the Climate Smart Tasmania: A 2020 Climate Change Strategy against the Sustainable Transport section as this was deemed as the only relevant section to the proposed activity
Sustainable Transport
6.5 LNG network promotion
The use of LNG will be reviewed for transport, however at present there is no LNG facility along the Midlands Highway that could be utilised for transport. If a facility was opened in the vicinity of Campbell Town then this option could be investigated.
6.7 Safe and fuel efficient driver training program
All operators will be put through a ‘Safe and fuel efficient driver training program’ if a suitable one in Tasmania is available
6.8 Freight Best Practice
Midlands Quarries will endeavour to have Freight Best Practice for all delivers from the quarry, this will be dependent on the delivery site for the material and will need to be assessed on an individual basis.
The effects of climate change on future operations is deemed to be minimal, continual monitoring of stormwater run off will be completed throughout the project to ensure that silt ponds are adequate in size in the event that more intense rainfall events occur over time .
Page 22 of 37
3.14 HERITAGE
An aboriginal assessment has been completed for the area by Gondwana Heritage Solutions with 2 sites found within the lease and not in a quarried area, these sites have been recommended to be marked on site with 10 metre no go zones. Otherwise the proposed site is clear from any Aboriginal Heritage issues. The report by Gondwana Heritage Solutions is in the appendix 1.7.
Gondwana Heritage Solution also completed a Historic Heritage Assessment of the site with no listed/ registered historic heritage places identified and the potential for historical heritage sites to be negligible. This report is included in the appendix 1.8.
The quarry lease boundary is the old Lake Leake Road, this will be preserved and is not included in the quarrying activity.
The old quarry sites at the northern end of the lease will also be preserved as they are located in the buffer zone to the Lake Leake Road.
3.15 SITES OF HIGH PUBLIC INTEREST
The proposed quarry site is not located in an area of public interest. The site is located on unused farming land.
3.16 MONITORING
A Project Management Plan (PMP) will be developed for the quarry based upon Shaw Contracting (Aust) P/L certified management systems which will cover the following 3 key areas
- Quality Management ISO 9001
- Safety Management AS4801 & Federal Safety Commission Accreditation
- Environmental Management ISO14001
Key environmental areas to be monitored during the operation will be
- Performance of the Weed Management Plan
- Water Quality of water leaving the site
- Noise and vibration during blasting operations
- Vegetation Monitoring

3.17 REHABILITATION
As the current site has little to no vegetation present due to the massive nature of the rock minimal topsoil and vegetation will be preserved. At the completion of the mining the quarry faces will be battered back to reduce the steep faces to make safe.
Local provenance species will be planted out in the quarry, these would consist of ground covers and grasses identified in the Flora and Fauna Assessment suitable to the harsh area.
As it is proposed to use mobile crushing equipment for the site there will be minimal effort required to remove infrastructure from the site. The site office and ablution facilities will be transportable units and will be removed along with all associated minor infrastructure such as fuel storage.
The nominated hardstand area will be rehabilitated with the visual screen bund. Any fixed concrete works or structure will be removed from site.
