PART B - Project Description

1. Proposal and background to the operation

Project Name

Expansion of existing crushed rock gravel quarry

Project Address

59 Musketts Road, Allonnah

Bruny Island

Background to the project

Mr Hansson currently operates a quarry at this site.

Due to increased demand for quarry materials on Bruny Island it is proposed to continue operation and expand the quarry (see project description below).

The quarry operates within a 1 hectare mining lease (current operations occupy approximately 1600m2), and the expanded operation will continue within the boundaries of this lease, (copy of lease is attached as appendix 1) The lease is renewable at 5 yearly intervals. Once approval has been given for the expanded operation MRT will review the size of the surety, but a new lease is not required.

The quarry has a planning permit for the operation (expired on 29 October 2009), and a new application has been submitted to Council for the expanded operation. This will be considered by Council once the EER process is complete.

The Hansson family has owned and operated the quarry for over 10 years. The operators have extensive experience in quarrying of non metallic materials, forestry operations, sawmilling, heavy transport operations and excavation machinery operation. They own some of the machinery necessary to operate the quarry. Recently, the installation of a small crusher and screening equipment has improved the capacity of the operation as a local supplier to the retail market.

There are no other commercial quarries on Bruny Island, and without this operation quarry material would have to be sourced from off the Island. This would increase the cost to both

public and private consumers by approximately 100% (Material can be supplied from Hansson’s quarry for an average of $30-35/m3, whereas material sourced from off Island costs $60 - 70/m3. The price difference is due to the cost of transporting quarry material on to the Island.)

Purpose of the quarry expansion

The existing quarry is operating at capacity and needs to expand to meet increased demand for materials for a number of large projects on Bruny Island, including:

• upgrading of the Bruny Island Main Road (9 000 m3 of material required over 2 years), • new Bruny Island Health Centre,

• forestry operations, and

• a number of smaller private projects.

Material is also sold to other retail suppliers.

The existing operation produces approximately 2000 m3 of quarry material of various grades per annum. With the recent installation of a small on site crusher the capacity to produce different materials, particularly higher grade road base and fine crushed rock has increased substantially. At the same time existing quarries at Pybus Hill, Lunawanna and Adventure

Bay have closed and the Hansson operation is the only commercial quarry operating on the Island.

The proposal is to expand the area of the quarry operation within the existing site boundaries and mining lease to meet the increased demand.

The expansion will not require any new structures. The area occupied by the existing quarry the mining lease area and the area of the proposed expansion are shown on map 2.

Machinery operating on the site

• 2 crushers (1 contract crusher operating for up to 4 weeks per annum, and 1 small crusher operating intermittently for short periods to meet local retail demand). The small crusher is owned by the operator is only used on an occasional basis when additional crushed rock is required.

• 1 front end loader

• 1excavator

The small on site crusher is too small to handle the volumes associated with large contracts. It is intended to use a contract crusher to crush and stockpile material. This will operate at the site for up to 4 weeks a year. The bulk of the annual requirement will be crushed and stockpiled during this period. The small crusher owned by Mr Hansson will be used intermittently when small amounts of additional material are required. The crushing equipment will not operate continuously.

Access roads

(Dillons Road and Musketts Road) will continue to be used and no new roads are required.

b) Timeframe of operation

The quarry will be an ongoing operation

c) Operating hours

It is proposed to extend operational times from 8.30am - 5.00pm 5 days per week, to 7am - 6.00pm weekdays and 8am to 4pm Saturdays.

The number of blasting shots will remain at the current level of 2 per annum. All blasting will be carried out in accordance with the Department of Mineral Resources’ requirements. (see part C.9 below).

d) Production rates

During crushing operations, the production rate will be a maximum of 2500m3 per week. This material will be crushed and stockpiled on site. It is not possible to accurately specify the exact time periods and amounts of material to be transported as DIER has not as yet specified the construction timetable.

3. ! Neighbour consultation

Occupiers of adjoining dwellings (3) have been informed of the proposed expansion. No objections have been raised. There are no occupied dwellings, other than that occupied by the operator, within 500m of the quarry face. A dwelling approximately 750m north east of the quarry face and another 550m to the north west are occupied intermittently (2-3 times per year). Owners has been informed of the expansion and no comment has been received. Location of the different dwellings is shown on Map 1.

4. ! Project Area

a) General site description

The quarry is located on a north facing slope with a slope angle of 1:10 near the existing quarry face, reducing to 1:25 in the area proposed for expansion.

The underlying rocks are bedded fossilised marine siltstones and mudstones. The bedrock in the vicinity of the quarry has a gentle slope from north to south of less than 5 degrees.

Land on which the expansion is planned is currently cleared pasture which has recently been ploughed for pasture grasses (the land will continue to be used for pasture grasses until it is incorporated into the quarry). The ploughed area is approximately 4 hectares in extent. The mining lease covers 1 hectare and the existing and proposed extended quarry will cover about 3000m2.

To the south of the cleared area, native bushland occurs (consisting predominantly of dry eucalypt woodland dominated by Eucalyptus obliqua with a grassy understorey). There is one large white gum (Eucalyptus viminalIs) to the east of the proposed quarry expansion area and scattered Eucalyptus globulus (Tasmanian blue gum) regrowth in the Eucalyptus obliqua forest to the south of the lease area. The expanded quarry will not extend into the treed area and no forest is to be cleared.

There are no permanent watercourses, wetlands or recharge basins on or near the site.

There is a minor water course that runs from the northern edge of the existing quarry northwards to Barnes Creek. A small retention pond is located on the watercourse some 35 metres downhill from the edge of the quarry. Flows in this water course are variable and water only flows directly from the quarry during times of high rainfall. Photo 1 shows the flow level out of the quarry immediately after a fall of 85mm in 36 hours. A small drainage channel has been installed at the northern edge of the quarry and stormwater from the quarry flows through this to the small water course and a retention pond downstream of the quarry. This arrangement uses the natural drainage lines. The drainage channel is heavily vegetated to minimise the risk of erosion, and siltation.

Photo 2. Settling pond after heavy rain event. This pond is located between the quarry and Musketts Road. Vegetation is maintained around the pond to minimise the risk of erosion.

A minor watercourse lies some 500 metres to the south west of the site. This water course only flows at times of high rainfall. No quarry operations or clearing will occur within 200 metres of this watercourse.

No nesting sites for the endangered swift parrot or forty spotted pardalote have been recorded in the vicinity.

Page 8: Quarry Expansion - Musketts Road Bruny Islandepa.tas.gov.au/documents/hansson_quarry_alonnah_eer.pdf · Quarry Expansion - Musketts Road Bruny Island Project description and environmental

The soils are shallow sandy clays (300-400mm in depth) with low fertility (Class 5 on DPI classification). They are suitable for grazing or forestry production only.

Average annual rainfall is approximately 800mm. There are no permanent water courses on the site. However, the small gully has intermittent flows and supports denser understorey vegetation including olearia spp, acacia spp, native cherry and allocasuarinas.

Bushland to the south and east supports a wide range of native mammals, birds, reptiles and invertebrates. These are typical of extensive areas of drier country on South and north Bruny Island, including large reserves in the immediate vicinity at Simpsons Point (360 ha), Lutregala Creek Forest Reserve (150 ha), two large forest reserves and a number of smaller private and public reserves.

b) Site use

The current quarry has been operating under a Council permit and mining lease for 10 years. The expansion area has been used for grazing and pasture production for over 50 years.

c) Land tenure

Private freehold. The current operator is the owner.

d) Surrounding land uses

The predominant land uses on surrounding land are grazing and forestry. Lower lying land adjacent to Bruny Island Main Road is used for grazing, whilst higher land is used for forestry on both private land and State Forest. Conservation constitutes a minor land use on the Lutgregala Creek Forest Reserve some 2 km to the east.

Some land in the vicinity has been purchased for private recreation purposes and 2 existing dwellings are used intermittently as holiday homes.

e) Soils and underlying rock type

The underlying rock is thin and medium bedded (100mm to 300mm) marine siltstone and mudstone with some calcareous beds.

These beds have a gentle (<5degrees) slope from north to south

Soils are shallow (average 300-400mm depth) infertile sandy loams formed under dry eucalypt closed woodland. There is no evidence of soil erosion.

4. ! Map and site plan

See maps 1 and 2 above. A plan of the operational area is included below as map 3.

5. ! Technical and Management alternatives

There are no known technical or management alternatives to the proposed operation. The quarry has operated successfully for a decade and operates in accordance with all existing controls and regulations.

PART C !Potential Environmental Impacts

1. Flora and Fauna

a) Native vegetation disturbance

No native vegetation or potential habitat for native fauna will be cleared. The area into which the quarry operation is to expand is recently ploughed pasture. The grass cover prior to ploughing was introduced pasture species.

The following advice has been received from Dr Wendy Potts, Senior Botanist, Threatened Species Section, Resource Management and Conservation Division, Department of Primary Industries, Parks, Water and Environment

TSS wouldn't recommend a threatened flora survey for this proposal as there is little potential for the species listed below (presumably those that have been recorded within 5km) to have persisted in ploughed pasture consisting of exotic pasture species. The risk of spreading Phytophthora and weeds will need to be addressed.

The presence of phytopthora is not evident on or near the quarry site. However, this area of Bruny Island has been subject to infestation by this fungus, particularly on land to the north. Accordingly, there is a risk of the quarry becoming a source for dispersal of the disease. The greatest risk arise from the introduction of phytopthora from off site locations.

b) Vegetation surveys

Survey not required (see a) above)

c) Pests, weeds and plant and animal diseases

Phytopthora

Phytophthera cinnamoni is not present in any of the vegetation on or near the site although there are some occurrences on South Bruny Island. This is a crushed rock quarry, and as noted in the quarry Code of Practice,

“crushed rock can be considered free of contamination by Phytopthora cinnamomi provided it is not contaminated with topsoil.”

The following measures are proposed to reduce the risk of contamination:

• Removal of topsoil before blasting to avoid contamination of the quarry rock with either phytopthora or weeds (see below for comments on weeds).

• Location of the stockpile so as to avoid material being washed back into the quarry working area.

• Management of the drainage system will be managed to avoid water and sediment build up in the floor of the quarry.

• Machinery will be washed down prior to its being brought on to the site.

Weeds

Areas of disturbed ground in the vicinity of the quarry host a variety of invasive weeds, including blackberry, ragwort and at least two species of thistle. Weed control is difficult as

13

Page 14: Quarry Expansion - Musketts Road Bruny Islandepa.tas.gov.au/documents/hansson_quarry_alonnah_eer.pdf · Quarry Expansion - Musketts Road Bruny Island Project description and environmental

they are spread continuously from other properties in the vicinity by wind borne seeds. Ragwort, in particular has become a major infestation in the vicinity as land previously used for grazing on an adjoining property is no longer actively used nor ragwort systematically removed, and has become seriously infested. Seeds from this infestation are spread continuously to adjoining properties.

Although the quarry owners take some measures to address the weeds problem - regular ploughing, spraying of thistles and mechanical removal - continued infestation from outside has made complete control difficult.

Removal and stockpiling of topsoil in a location well removed from the quarry face and from crushed material stockpiles minimises the risk of weeds being spread to the crushed material. The current stockpile will be managed to reduce weed infestation and the risk of spreading Phytophthera. It is proposed to

• reduce the height of the stockpile to maintain the soil in a healthy condition,• remove weeds from the stockpile by spraying and mechanical means, and

• plant the stockpile with local grasses and shrubs (this will also help reduce runoff from the stockpile and contamination of the crushed material.).

2. Rivers, creeks, wetlands and drainage.

A small intermittent watercourse runs from the site towards the north. This watercourse emanates from the quarry but only runs in times of high rainfall. The natural slope of the quarry floor means that water collects in the quarry. A stormwater management system is currently in place as a condition of the existing lease. The condition requires the lessee to:

provide drainage work and settling ponds to prevent erosion, escape of silt from the site in order and to ensure successful protection of the environment.

A channel has been created at the northern edge of the quarry to allow runoff into a settling pond located between the quarry and Musketts Road. As well as providing drainage for the quarry it prevents mud from settling out on the quarry floor. Vegetation has been maintained between the quarry and Musketts Road and in the drainage channel to prevent erosion.This work was carried out as part of the initial development of the quarry and has been done to satisfaction of the Director Mines. The existing arrangement will be maintained. The location of the small watercourse and settling pond are shown on Maps 2 and 3.

There will be no effect on the intermittent watercourse 500 meters to the west of the quarry site.

3. Significant areas

The quarry site is not located adjacent to or within any existing reserved area. The nearest reserve is Forest reserve some 2 km to the east.

4.Coastal Zone

No part of the proposal lies within 300m of the coastline

5. Marine areas

There will be no impact on marine areas.

14

Page 15: Quarry Expansion - Musketts Road Bruny Islandepa.tas.gov.au/documents/hansson_quarry_alonnah_eer.pdf · Quarry Expansion - Musketts Road Bruny Island Project description and environmental

6. Air emissions

The only potential emissions will be dust from blasting and crushing operations.

Measures to reduce dust emissions rom the blasting operation are spelt out in C. 9 below.

The crusher operates with dust suppression equipment in place that meets current specifications. The material being crushed does not produce large quantities of small sized particles.

7. Liquid effluent

No liquid effluent will be produced apart from run off to the small watercourse and settling pond.

8. Solid wastes

No solid wastes will be produced. Topsoil will be removed prior to blasting and stockpiled for rehabilitation following cessation of quarry operations in accordance with the lease. The current stockpile will be maintained and managed as set out in C.1 above, (see photo 6 above).

9. Blasting

Blasting will only be carried out on 2 occasions per annum. Details of the blasting operation have been requested from Explosive Engineering Pty Ltd. This firm has carried out blasting for the existing quarry.

10. Noise emissions

a) Noise

The existing quarry operates in a rural environment with typical background noise levels of 40-55dBA, depending on time and weather conditions The quarry is surrounded by trees and is on a wind exposed north westerly slope. Strong winds are common and at such times high back ground noise levels are experienced.

The primary noise sources of the quarry operation are blasting, crushing and truck movements.

No new or larger machinery is proposed for the expanded operation. The main difference will be in the extended operating hours and the volume of traffic generated.

• Blasting - only two blasting events will occur per annum. Measures to manage noise effects are detailed in C.9.

• Crushing - the current crushing operation produces raised noise levels at distances of up to 200 metres from the quarry site. Although these have not been measured they are equivalent to noise generated by passing heavy traffic on Bruny Island Main Road at the same distance. No noticeable noise impacts from the crusher operation have been identified at distances greater than 500 metres. It should be noted that continuous crushing will only occur for up to 4 weeks per year. This will be carried out by an outside contractor. The new stockpile will be sited towards the northern edge of the quarry and the crusher will be located between the quarry face and the stockpile of

15

Page 16: Quarry Expansion - Musketts Road Bruny Islandepa.tas.gov.au/documents/hansson_quarry_alonnah_eer.pdf · Quarry Expansion - Musketts Road Bruny Island Project description and environmental

crushed material. This will act as a noise barrier. In addition, houses to the west on Dillons Road, the unoccupied houses to the north west and to the east on Bruny Island Main Road are protected from direct noise transmissions by shallow ridges that run south east - north west. The location of the quarry near a watercourse depression between these ridges provides some screening for noise impacts to the east and west.

• Vehicles - The average number of vehicles entering and leaving site is expected to be a maximum of 10 per day. Other heavy vehicles operate over this section of Bruny Island Main Road and including log trucks (12 vehicle movements per day), Council trucks and road building machinery (8 vehicle movements per day), water cartage vehicles (6 movements per day in summer), delivery vehicles (10 vehicle movements per day) larger recreational vehicles (variable but in the peak holiday period up to 100 vehicle movements per day). In addition log trucks use Dillons Road and nearby Wooreddy Road.

On the basis of the above the most significnt increase in noise will be from the movement of heavy vehicles. This noise will be intermittent. No measures are proposed to reduce or limit noise from this source, beyond restricting operating hours (see above). Topography, distance separation and location of the crusher behind the stockpile will significantly reduce any noise emissions from the quarry operation.

b) Sensitive uses

There are no sensitive uses within 100 metres of the quarry site.

Apart from the operator’s dwelling there are 4 dwellings within 1 km of the site. There are no dwellings (other than the operator’s) within 500m of the site.

Consultation has taken place with residents of the occupied dwellings and none of these have identified any noise issues, dust or other issues with the quarry operation. The only noise of which they are aware is associated with truck movements, but it was not identified as an issue.

There is one unoccupied dwelling 550 metres and another some 750 metres from the site They are used occasionally as a holiday residences. They are both on Bruny Island Main Road and the owners have not identified any noise or other issues with heavy vehicle traffic or the quarry operation.

It is proposed to continue with screen planting on the northern perimeter of the quarry in order to maintain existing native vegetation cover as a visual management measure. The quarry is not visible from Bruny Island Main Road because of these plantings (see Photo 9).

11. Transport impacts

The expansion of the quarry will result in an increase in the number of heavy truck movements. The details of the expected increase are given in C.10 above.

The cartage of road material to Great Bay for the reconstruction of the Bruny Island Main Road will generate 50 truck movements per day. The timing of this is unknown as it is subject to DIER planning. Indications from DIER are that it is unlikely to be during the peak visitor season. This activity will be limited in duration (it will involve a total of 9000m3 of crushed material) and is likely to be for a total of 35 days spread over a period of 18 months.

16

Page 17: Quarry Expansion - Musketts Road Bruny Islandepa.tas.gov.au/documents/hansson_quarry_alonnah_eer.pdf · Quarry Expansion - Musketts Road Bruny Island Project description and environmental

Apart from this the average number of truck movements will be 10 per day. Trucks will use Musketts Road, Dillons Road and the Bruny Island Main Road. Destinations will be various and depend upon demand from retail customers. Given that the main demand is for material for domestic purposes, destinations are likely to be Adventure Bay, Alonnah, Lunawanna and the Cloudy Bay area. These localities are experiencing increased levels of residential and tourism infrastructure development.

The vehicles to be used for general delivery of material will be fixed axle tracks capable of carrying 8m3 of crushed rock. Tandem trailers with a total capacity of 15m3will be used for the road construction work

Apart from the concentrated activity associated with the road reconstruction, environmental impacts associated with truck movements will be limited in terms of noise, traffic volumes and overall amenity.

No additional measures are proposed to mitigate these impacts. Discussions will be held with DIER regarding the minimisation of impacts for road material cartage, particularly through Great Bay and at the public parking area at the Neck.

12. Other impacts

a) Amenity of existing residences and sensitive uses

There are no other impacts on off site uses over those identified above.

b) Future use of land within the site

The quarry expansion will result in a minor loss of agricultural land (<1ha). The land is classified as Class 5-6 in accordance with the State Policy on Agricultural Land and there are no economic losses arising from the loss of this land. The future use of the land is unknown.

c) Visual impacts

The quarry is almost totally screened from Bruny Island main Road. It is not visible from any other public place. Screening has significantly softened the visual impact of the quarry and this screening will be increased as part of the expanded operation. In particular, recent understorey growth has reduced the visibility of the quarry. Vegetation screening will be maintained and extended to ensure that there is no visual impact of the expanded quarry operation.

17

Page 18: Quarry Expansion - Musketts Road Bruny Islandepa.tas.gov.au/documents/hansson_quarry_alonnah_eer.pdf · Quarry Expansion - Musketts Road Bruny Island Project description and environmental

d) Economic and social benefits

There will be an increase in employment as a result of this expansion. The quarry requires two operators. Additional employment is generated in transport of the material, both by the operator and other cartage contractors on the Island.

The cost of using material from off Island sources would significantly increase the cost of road, and building construction on Bruny Island. In particular, projects such as road upgrading and maintenance by State and local government would be much higher, and there would be a reduced capacity for these projects to be undertaken. Similarly, the cost of major public projects such as the Health Centre would be increased.

13. Dangerous goods and chemicals

a) Use of dangerous goods

Explosives will be used on site. However, these will be under the control of a qualified operator and no explosives will be stored on site.

Fuel for the operation of the of the crusher, loader/excavator and trucks will be stored off site in an existing transport depot owned and operated by the quarry operator. Trucks will be refuelled off site. Fuel for the loader/excavator and crusher will be transported to the site in fuel containers and transferred to the machines as required.

No other dangerous goods or chemicals will be used in the operation.

14. Site contamination

The existing quarry operation has not resulted in any site contamination. No toxic materials or fuels are stored on site. The same management measures used in that operation will continue and contamination is not expected to occur.

15. Aboriginal cultural heritage

The following advice has been received from Aboriginal Heritage Tasmania.

Aboriginal Heritage Tasmania have completed a search of the Tasmanian Aboriginal Site Index (TASI) regarding the proposed expansion of the Hannsons Quarry and can advise that there are no Aboriginal heritage sites recorded within or close to the property. Due to the reasonably small size of the expansion (50 metres) and the area being highly disturbed it is believed that the area has a low probability of Aboriginal heritage being present.

Accordingly there is no requirement for an Aboriginal heritage investigation and Aboriginal Heritage Tasmania have no objection to the project proceeding.

Please be aware that all Aboriginal heritage is protected under the Aboriginal Relics Act 1975. If at any time during works you suspect Aboriginal heritage, cease works immediately and contact Aboriginal Heritage Tasmania for advice.

16. Sites of public interest

There are no sites of high public interest on or adjacent to the area proposed for the quarry expansion.

17. Rehabilitation

The current lease has requirements for rehabilitation. These are:

a) Rehabilitation of worked out areas, including revegetation of the land surface, to the satisfaction of the Director of Mines.

b) Retention of all tailings within the leased area, and rehabilitation of tailings areas to the satisfaction of the Director of Mines.

c) Removal of all structures, equipment hazardous substances and debris from the lease area.

d) Rehabilitation of worked out areas concurrently with mining operations so that the unrehabilitated area does not exceed 0.25 hectares at any time except with the approval of the Director of Mines.

Rehabilitation is to take place after cessation of mining operations or in accordance with condition d). The current working area is approximately 1600m2, and could extend to 3000m2 in the current expansion program. The intention is also to deepen the quarry face so horizontal expansion of the quarry will proceed only slowly. The quarry floor is used as part of the operation for crushing and stockpiling of crushed material. It is unlikely that rehabilitation will commence within the proposed 10 year time frame of this operation.

PART D Management Commitments

1. Management

There are sixteen key management commitments

1) Plantings on the northern perimeter of the quarry will be extended and thickened to reduce visual impact to the north. Existing plantings are being supplemented with understorey and extended to the east to provide an additional visual barrier. Local plant species found on the site are being used for this work.

2) Drainage work and a settling pond as currently implemented will be maintained.

3) Water will not be allowed to pond on the floor of the quarry for extended periods.

4) Topsoil will be removed and stockpiled in an area separate from quarry workings prior to blasting operations.

5) The stockpile will be managed to reduce weeds and planted out to reduce erosion and runoff of stockpiled material.

6) Machinery to be used on site will be washed down prior to entering the site.

7) Crushed material will be stockpiled at the northern edge of the quarry. The crusher will work between this stockpile and the quarry face.

8) All blasting operations will be conducted by professional, trained operators in accordance with all existing regulations. Blasting will occur on no more than two occasions per annum.

9) No explosives, fuel or other hazardous materials will be stored on site, to minimise any risk of contamination or pollution.

10) The quarry site will be rehabilitated in accordance with specifications set out in C.17 above.

11) Management recommendations from Aboriginal Heritage Tasmania will be adhered to.

12) Consultation will be held with DIER to determine the best way to reduce impacts during cartage to major project sites. Any recommendations made by DIER will be transmitted to the EPA and implemented as part of the operation.

13) Occupants of all dwellings within 1km of the site will be kept informed of operations that could have an impact - specifically blasting and increased truck movements.

14) The school bus operator and the operator of tourist buses (up to 4 buses per day) will be kept informed of periods of increased truck movement, particularly across the Bruny Island Neck.

15) Discussions will be held with DIER to arrange permanent trucks turning warning signs east and west of the junction of BI Main Road and Dillons Road.

16) Permission will be sought to erect temporary warning signs during times of increased truck movements.
