Extension of Operations, Calder Sand

2.0 Summary

This Environmental Effects Report (EER) has been prepared to support the Development Application

by Summers Transport to the Waratah Wynyard Council (WWC) and the Tasmania Department of

Primary Industries, Parks, Water and Environment (DPIPWE).

The proposal involves increasing pit production (gravel and sand) at an existing pit site from <5,000

m3 to 15,000 m

3 of material per year. The activity is a Level 2 Activity as defined by Schedule 2 of

the Environmental Management and Pollution Control Act 1994 (EMPCA).

The EER is required for Level 2 Activities to describe the proposed operations, potential impacts and

proposed management measures. The EER aims to provide this information to the decision-making

authorities, the Board of Environmental Management and Pollution Control (‘the Board’), the

Council, and the general public.

A permit application for the changes to operation will be considered by WWC in accordance with

Section 57 of the Land Use and Planning Approvals Act 1993 (LUPAA).

4.0 Proposal Description

4.1 Project Description

It is proposed that an existing sand extraction pit, previously operated as an EPA Level 1 activity to

obtain gravel and sand, be extended, sequentially and properly developed. The source material will

provide improved quality sand and screened aggregates of various grades for the concrete supply,

brick and masonry manufacturing and general construction industry when screened.

The deposit has been explored using excavator test pits. The exploration revealed that the deposit is

highly variable in particle size distribution. This is considered beneficial as a greater number of

material types can be supplied, but it means that the lateral site disturbance potential is difficult to

minimise. The mapped extent of the deposit covers only part of the entire leased area.

The deposit covers an area of approximately 8.7 hectares, approximately half of which has been

previously worked. Assuming an average depth of the deposit of 4m (unworked at 6m depth of

extractable material and worked at 2m) the deposit contains in the order of 350,000 cubic metres of

material. Assuming that only 60% is worth extracting or otherwise available, a lifetime of 14 years is

envisaged at maximum production.

Because of the nature of the deposit, the extraction process is intended to operate with shallow (3-4m)

benches in a number of areas throughout the site, each providing varying materials. With a screening

plant on site, the operation is to extract up to 15,000 cubic metres per year.

The mobile screening plant (no crushing or other process is required) will generally be located in the

central portion of the existing pit visible in Figure 2. This is 800m away from the nearest residence to

the south (figure 2). There is a ridge between the quarry and the nearest residence that has a dense

group of trees growing on it that reduce noise and visual impacts (figure 2).

Rehabilitation of the pits will be sequential, with existing topsoil removed, stockpiled and replaced as

each area is completed. Runoff will be contained and reused as dust control, or fed through silt dams

and associated systems to control runoff quality. Access is through existing roadways and tracks.

Alan Summers Transport Pty Ltd Extension of Operations – Oct 2012

Environmental Service and Design Pty Ltd – PAF#4561

The extended operations would officially commence on receipt of all necessary permits; the project is

forecast to operate for 15 years.

Operating hours will be in accordance with the Quarry Code of Practice; “Operating hours of quarries

in the vicinity of residential premises, to 0700 to 1900 hours, Mondays to Fridays and 0800 to 1600

hours Saturdays”. 1

The rate of production will be will be variable as production will be performed on an as needs basis.

Maximum production rate will be 15,000 m3 per year

4.2 Project area

The site is located on Elphinstones Road, off Calder Road, some 14 km south of Wynyard (Figure 1).

There are no wetlands or waterways near the project area and the nearest residence is approximately

700 m away from the edge of the proposed active area (Figure 2). The residence is shielded by

approximately 500 m of vegetation with some slight elevation between the centre of the mining lease

to the location of the residence.

Historical and current use of the site is for sand and gravel extraction

1 Commitment: Operating hours will abide by the Quarry code of Practice; “Operating hours of quarries in the

vicinity of residential premises, to 0700 to 1900 hours, Mondays to Fridays and 0800 to 1600 hours Saturdays”.

4.3 Land Tenure

Summers Sand and Gravel Pit comprises land described as; PID 2532676, Crown land controlled by

Forestry Tasmania, and is located at the end of Elphinstones Road, off Calder Road, Calder, via

Wynyard. Mining leases numbered 45M/1975 of 34 hectares, and 11M/2007 of 4 hectares are

registered in the names of Kay PC and Summers DR indicated in Figure 3 below.

Accessed (solely) through Elphinstones Road, Summers Pit is a small pit formerly operated by

Waratah Wynyard Council, on Mining Lease 8M/1999. This pit is largely depleted, and has limited

available reserves. No rehabilitation by Council has apparently occurred in this pit area. It is

understood that no council extraction has occurred for many years.

Figure 3 Mining Lease Plan

4.4 Map and Site Plan

Refer to Figure 1 for a general location map and Figure 2 for the area of the proposal, found in mining

leases 45M/1975, and 11M/2007, indicated in Figure 3. A mining plan can be found as Appendix 4,

which covers rehabilitation of the site.

4.5 Rationale and Alternatives

The deposit provides a valuable resource of materials to the growing marketplace. The deposit is

located on an environmentally degraded site. No alternatives are considered, although there are other

deposits in the area. Alternative routes are restricted by topography, tenure and available roads.

5.0 Potential environmental effects

5.1 Flora and Fauna

The property is native forest, partially harvested and under regrowth. Following many years of

selective and coupe logging, very few large trees remain, and the environment is subsequently

Page 11: Environmental Effects Report Alan Summers Transport Pty ... Summers... · Prepared For: Allan Summers Transport Pty Ltd Version: Reviewed/Approved By Date Draft 1 Ian Ferris 01/042011

10 | P a g e

Alan Summers Transport Pty Ltd Extension of Operations – Oct 2012

Environmental Service and Design Pty Ltd – PAF#4561

degraded. The vegetation surrounding the pit site is largely young eucalypt, with undergrowth of

various pioneer regrowth species e.g. Silver Wattle, Dogwood, and bracken fern. Refer to Appendix 1

vegetation report “SUMMERS QUARRY, ELPHINSTONE ROAD, CALDER - FLORA and

FAUNA HABITAT SURVEY” of June 2011.

Native vegetation will be disturbed/cleared during the process of extracting the sand and gravel from

the site. The total area of vegetation that will be cleared is 10.8 ha, although 9 ha have already been

cleared previously. This additional clearing will occur over time and be progressively rehabilitated as

per the mining plan (Appendix 4).

The site does not appear to have any record of threatened species or habitats, RAMSAR wetlands, or

nationally threatened species and communities, nationally listed migratory species, Commonwealth

Environment Protection and Biodiversity Conservation Act 1999.

The presence of; Tasmanian Wedge-Tail Eagles (Aquila audax fleayi), Tasmanian Devils

(Sarcophilus harrisii) and Spotted Tail Quolls (Dasyurus maculates) is possible, but these are

roaming species and unlikely to reside near or be impacted by this localized activity. The site has been

selectively logged and quarried in part. No nest sites or other indicators were observed, apart from

Devil scats within the pit.

Details of the proposed management processes for weeds and Phytophthora cinnamomi are found in

Appendix 3.

The extension of the quarry within mining lease 45M/1975 will only go towards the northern

boundary to where vegetation has recently been cleared. The pit in mining lease 11M/2007 has much

more scope for expansion.

A site drainage plan and rehabilitation plan are incorporated into the Mining Plan (Appendix 4)

5.2 Rivers, creeks and estuaries

Typically for undulating hilltop sites, there are stormwater exit points on the site at a number of

locations. All issue points will be controlled by drains and fed through silt dams to ensure that runoff

Page 12: Environmental Effects Report Alan Summers Transport Pty ... Summers... · Prepared For: Allan Summers Transport Pty Ltd Version: Reviewed/Approved By Date Draft 1 Ian Ferris 01/042011

is of satisfactory quality.2 No further infrastructure is required for the site due to water use remaining

constant.

Potential impacts to the Inglis River are considered minor due to separation distances of over 200 m to

the north west at its closet point, but will be addressed by provision of drainage control, silt traps, and

swamp areas which are expanded in the mining plan (Appendix 4).

The creeks in the local area have the potential to be a foraging ground for the giant fresh water

crayfish (Astocopsis gouldi). Measures to protect the creeks for the crayfish include the use of silt

traps and avoiding wet areas surrounding watercourses.

Figure 4 below shows the drainage regime, and Figure 6 in the Mining Plan indicates the areas not

proposed for disturbance.

2 Commitment: All issue points will be controlled by drains and fed through silt dams and associated swamps to

ensure that runoff is of satisfactory quality

Figure 4: Drainage lines

5.3 Air Emissions

The proposal has the potential to produce dust and minor vehicle exhaust emissions. Dust from the

trucks and the screener will provide most of the potential emissions. Truck dust emission management

involves use of a water truck where necessary3. Drivers will be instructed to reduce speed when

driving past residential areas, although road conditions generally result in low speeds. No complaints

have been received relating to dust produced by the site, even though production has occurred for

many years. Screener emissions are negligible as the source material is generally moist.

Note: The nearest residence is approximately 700 metres from the project area; there are a total of 4

residences on/ near Elphinstones Road who may potentially be affected by dust emissions. The owner

of the quarry has visited all four residences to discuss the project and gave them his contact details in

3 Commitment: effective dust control strategies throughout the site including use of a water cart on traffic areas,

water sprays on processing equipment whenever necessary will be implemented.

order to maintain good relationships with the occupants. Regular communications between the owner

and the occupants will ensure that any potential dust emissions emanating from the quarry and

impacting upon their properties will be promptly managed and addressed.

5.4 Liquid Effluent

The only liquid waste that could be produced is oil and fuel spills, although these are stored in bunds.

No permanent toilet facility is proposed for the site. Chemical toilet facilities will be provided as

required during any periods of high activity. Spillage kits are available to manage oil and fuel spills.4

5.5 Solid Wastes

The topsoil /overburden materials that are accrued through the operations will be kept on the site and

used progressively for rehabilitation as needed. Other solid waste including general litter waste such

as paper, plastic, 5 and waste metals will be removed from site as produced, for proper disposal6.

5.6 Noise emissions

The two principle sources of noise emissions from the site are the screening plant and loader/truck

movements. The trucks operate on public roads and currently meet required noise emission levels.

The screening plant is located in the centre of the operation (see Figure 2) and is more than 350m

from any residences. No blasting or drilling occurs on site.

Note: As per Section 5.3, the nearest residence is approximately 700 metres from the project area;

there are a total of 4 residences on/ near Elphinstones Road who may potentially be affected by noise

emissions. The owner of the quarry has visited all four residences to discuss the project and gave

them his contact details in order to maintain good relationships with the occupants. Regular

communications between the owner and the occupants will ensure that any potential noise emissions

emanating from the quarry and impacting upon their properties will be promptly managed and

addressed.

5.7 Transport impacts

The number of truck movements (inwards and outwards) will be 10 per day average, at maximum

level of production, with a maximum expected of 20 per day. The operation is small, and has limited

scope for increase. Note that current truck movements equate to approximately 4 movements per day.

4 Commitment: A Spill kit will be available for use in controlling fuel or oil spillages.

5 Commitment: Solid litter waste will be removed from site for proper disposal on a daily basis

6 Commitment: Waste metals will be removed from site for proper disposal

Environmental Service and Design Pty Ltd – PAF#4561

5.8 Dangerous substances and chemicals

The only dangerous chemical in use for the duration of the operation is diesel fuel. Fuel is not stored

on site.7

5.9 Site contamination

Hydrocarbon contamination is the only significant source of contamination. Any spills will be

controlled (refer to 5.2 above), and residue removed to appropriate disposal. No storage of

Hydrocarbon on site, and any bought on site will be contained within a bund.

5.10 Sustainability and climate change

The site will be maintaining a similar level of production to that previously, and will not have an

increase in greenhouse gas emission. The operation will not be adversely affected by climate change.

The current climate in the area was reviewed. Rainfall is approximately 1040 mm per annum. Wind

direction is predominantly from a westerly direction, with north- and south westerly wind

subdominant.

5.11 Rehabilitation

Revegetation of the final surface has not been detail-designed, as final conditions and requirements

for the site may alter. It is intended that the final site is similar to the existing site with a surrounding

vegetation slope. The soil layer will be retained in stockpiles and progressively used on the

boundaries of excavations and fully replaced at completion. 8 The Mining Plan details the process

and areas to be rehabilitated.

The pits will be progressively rehabilitated as appropriate to allow regeneration to take place in a

controlled manner and to minimize damage to the environment.9

7 Commitment: No fuel will be stored on site.

8 Commitment: The soil layer will be retained in stockpiles and progressively used on the boundaries of

excavations and fully replaced at completion 9 Commitment: The pits will be progressively rehabilitated as appropriate to allow regeneration to take place in

Introduction:

This survey covers two adjacent mining leases 45M/1975 and 11M/2007 which are located within

state forest in the Calder Hills approximately 20km to the south of Wynyard. Both leases are currently

granted to Summers Transport Pty Ltd which quarries and grades sands and gravels principally for the

local building and landscape industries.

The Company is making application to the Environment Protection Authority to extend the existing

open pit and quarry.

Objectives: The objectives of this survey were to;

Undertake a desktop survey to confirm the known biological records and the natural values

present within the two lots and within 5,000 metres of the site.

Undertake a field survey of the two mining leases to observe and record the natural values

present including the vegetation types and plant communities, the flora and in particular any

threatened species and potential habitat for species of threatened fauna.

Determine the possible impacts of the proposed quarry extensions on the natural values

present and make recommendations on how those impacts can be minimized.

Site Location:

FIGURE 1. Location of quarry and study area.

Site Description:

The present quarry and pit workings are located on a low gravelly ridgeline which is bounded by two

gullies and small creek-lines which flow into the nearby Inglis River. The Inglis River is located to

the immediate west of the site and within a deeper valley. The area is well forested but much of it has

been subject to forestry activities over many years. To the east and along Calder Road is mainly

agricultural land, and to the south, forestry plantations.

A number of other quarries and gravel pits are located on ridgelines to the north of this site and

throughout the Calder Hills.

THREATENED FLORA:

No species of threatened flora which are listed under the Tasmanian Threatened Species Conservation

Act 1995 and/or the Commonwealth Environment Protection and Biodiversity Conservation Act 1999

are recorded on the “Natural Values Atlas” database as occurring within 3,000 metres of the study

area reference point.

One species of threatened flora is recorded on the “Natural Values Atlas” database as occurring within

5,000 metres of the study area.

Lachnagrostis scabra subsp scabra, the Rough Blowngrass is known from a single 1995

record located about 5,000 metres to the north-west of the study area. The species is listed as

being rare under the Tasmanian Act.

THREATENED FAUNA:

Four species of threatened fauna which are listed under the above Acts are recorded on the database as

occurring from within 3,000 metres of the study area. No threatened species has been recorded from

within 1,000 metres of the site.

White (Grey) Goshawk Accipiter novaehollandiae is listed as an endangered species under

the Tasmanian Act. There are two records on the database one from the 1997 and the other

about 2002.

Wedge-tailed Eagle Aquila audax subsp fleayi. The Tasmanian subspecies is listed as being

endangered under both State and Commonwealth Acts. It required large trees within old-

growth forest for nesting. There is one record from 2002.

Spotted-tailed Quoll Dasyurus maculatus subsp maculatus is listed as being rare in Tasmania

and vulnerable nationally. There are three records from around the mid 1990’s.

Giant Freshwater Crayfish (Lobster) Astacopsis gouldi is considered to be a vulnerable

species in Tasmania and nationally. There are 3 records from within 2,500 metres and a

further 5 from within 3,000 metres. All are dated from between 1999 and 2004.

There are further records of the above threatened species from between 3,000 metres and 5,000 metres

of the study area reference point.

White (Grey) Goshawk. 13 records, (1977 – 1981 x11, 1997 x1, 2002 x1)

Wedge-tailed Eagle. 7 records, (1977 – 1981 x6, 2002 x1)

Spotted-tailed Quoll. 1 record. (1995)

The following eight threatened species could occur in the locality based on habitat mapping and the

known geographical range of each.

White-bellied Sea-eagle Haliaeetus leucogaster. The species is considered to be vulnerable in

Tasmania. It is a bird of the coast and of inland lakes and waterways and often follows the

larger rivers such as the Inglis when hunting.

Tasmanian Masked Owl Tyoto novaehollandiae subsp castanops The Tasmanian subspecies

of the Masked Owl is endangered in Tasmania and is listed as being vulnerable nationally.

The species required large hollows in old-growth forest for nesting.

Swift Parrot Lathamus discolor is recognized as an endangered species in Tasmania and

nationally. The bird breeds in Tasmania over summer and requires tree hollows for nesting,

but over-winters on the mainland.

Azure Kingfisher Ceyx azureus subsp diemensis. The Tasmanian subspecies is listed as being

endangered under both State and Commonwealth Acts. It is localised on the rivers of the

north-west and western Tasmania.

Eastern Barred Bandicoot Parameles gunnii is quite widespread in Tasmania but is listed as

being vulnerable under the Commonwealth Act as it is a threatened species on mainland

Australia.

Australian Grayling Prototroctes mareana is a native fish which is considered to be

vulnerable in the State and Nationally.

Eastern Dwarf Galaxia Galaxiella pusillus. Is a small native fish which is listed as being

vulnerable under both Acts.

Hydrobiid Snail (Table Cape) Beddomeia capensis has a limited occurrence in the north-west

and is considered to be endangered in Tasmania.

Field Survey:

Methodology: The field survey was undertaken on foot and focused on the area of the two leases, the

range of vegetation types in the locality and potential habitat for threatened species of fauna such as

the creek-lines.

Vascular plant species were recorded; vegetation communities were observed and cross-referenced

with the TasVeg map sourced from the Natural Values Atlas database.

The field survey was conducted on the Tuesday 4th May 2011.

Limitations: This survey was conducted in late autumn when few species are in flower. No botanical

survey can guarantee that all flora will be observed and recorded in a single survey in one year due to

seasonal and annual variation in abundance and the possible absence of flowers and fertile material

for identification. Ephemeral species which may have been present includes species of orchids, lilies,

herbs grasses and other graminoids. However all significant species known to occur in the study areas

and their environs have been considered in this report.

Field Survey Results:

The area of the lease was divided into 5 sub-survey areas for the purpose of the on the ground survey.

The Inglis River is outside of the quarry lease and was not included in this survey.

AREA 1: Ridgeline with active quarry, gravel pits and operational area, including the area

recently cleared of trees and vegetation and proposed for the extension of the quarrying

operations. This area also included all of lease 11M/2007.

AREA 2: Creek-line and slopes to the north.

AREA 3: Creek-line and slopes to the south.

AREA 4: Forested ridgeline to the south covering the southern 30% of the main lease.

Environmental Service and Design Pty Ltd – PAF#4561

AREA 5: Eastern area of the lease to the north and south of the access road and property

entrance

AREA 1: Ridgeline with active quarry, gravel pits and operational area, including the area recently

cleared of trees and vegetation and proposed for the extension of the quarrying operations.

The gravel deposit in this locality appears to form a capping along the ridgelines which also

corresponds with the extent of the vegetation community Eucalyptus nitida Wet Forest (WNU). This

is at variance with the TasVeg map of the locality which does not show any E. nitida Forest.

A large proportion of this community has been previously cleared where the quarry and pits are now

located and a further area of the community has been cleared quite recently with the intention of

extending the pit and quarry. The extent of this community is now limited to a narrow band around

the periphery of the pit, quarry and cleared areas. The understorey where it is still present tends to be

scrubby with Leptospermum scoparium being the dominant species.

There was probably more diversity in the composition of the understorey prior to past and recent

clearing. The community has been impacted by the previous quarrying and gravel extraction

operations and by the recently clearing of what was said to be regrowth forest from previous forestry

activities. The community in this location however is not of high conservation significance. No

threatened species of flora were observed and there was little if any significant fauna habitat. No old-

growth trees or trees with hollows were observed. Tracks of Tasmanian Devil Sarcophilus harrisii

were observed in one location within the area of the gravel pit.

AREA 2: Creek-line and slopes to the north.

While only a short section of this creek passes through the actual lease about one kilometre of the

creek is adjacent to the lease and shares that part of the catchment. There is the potential therefore for

the quarry operations to have an impact on that length of the creek.

The vegetation community which extends along this creek-line is Acacia dealbata Forest (NAD)

which is in accordance with the TasVeg map although the community extends further up the creek

than is detailed on TasVeg. The community is of interest as it appears to be in a relatively pure form

with just a few emergent Eucalyptus obliqua. The understorey is typically a fern-gully particularly

Page 29: Environmental Effects Report Alan Summers Transport Pty ... Summers... · Prepared For: Allan Summers Transport Pty Ltd Version: Reviewed/Approved By Date Draft 1 Ian Ferris 01/042011

28 | P a g e

adjacent to the creek with the Soft Treefern Dicksonia antarctica dominating. The understorey on the

lower slopes is typical of wet forest with species such as Dogwood Pomaderris apetala, Nematolepis

squamea (Satinwood) and Coprosma quadrifida. No threatened species of plants were observed in

this creek area.

Although a minor creek with few deep pools, it had a good regular flow, and with its proximity to the

Inglis River it is likely to be foraging habitat for Astacopsis gouldi the Giant Freshwater Crayfish

(Lobster) and important habitat for juveniles of the species. Juveniles tend to inhabit minor creeks for

protection from predation.

The effective management of drainage from the adjacent pit and quarry will be essential in order to

avoid siltation and/or contamination of this creek and possible impact on the Crayfish, (Lobster)

habitat.

There are additional pits and quarries located to the north of this lease area (within other leasehold

areas) which also have the potential to impact on this creek. These pits are well illustrated on both the

TasVeg map and the aerial photo included with this report.

AREA 3: Creek-line and slopes to the south.

The upper reaches of this creek-line extends east to west and adjacent to the operational pit and

quarry. The creek-line as it extends westwards is also adjacent to but outside of the smaller of the two

leases 11M/2007.

Although the creek-line extends through a well defined gully there was no free water present in the

upper reaches of the creek at the time of the survey, and it is likely to flow only following rain events.

Permanent water flows are likely to be present lower down the catchment and closer to the Inglis

River.

The vegetation community along the creek-line was similar to the northern creek with Acacia

dealbata Forest although there were more Blackwood Acacia melanoxylon and Stringybarks

Eucalyptus obliqua present than along the northern creek. The community also extended further up

the creeks catchment than is mapped on TasVeg.

No threatened species of plants were observed and the habitat was not considered suitable for the

Giant Crayfish, although such habitat may be present in the lower reaches of the creek outside the

lease and this survey area.

A few burrows of a Burrowing Crayfish were observed along the creek bank. The actual species was

not determined although the limited numbers of burrows would indicate that it was not optimum

habitat, although more suitable habitat is likely to be present in the lower reaches of the creek. The

Burrowing Crayfish would be unlikely to be one of the known threatened species in this location.

The effective management of drainage from the adjacent pit and quarry and also from future

operations within mining lease 11M/2007 will also be essential in this location in order to avoid

siltation and/or contamination of this creek.

AREA 4: Forested Ridgeline to the south.

This ridgeline takes up the southern 30% of the main lease area and does not appear to contain

significant gravel deposits. The ridge is separated from the current pit and quarry by the creek-line

surveyed as Area 3. The ridgeline is composed of semi-mature forest which has obviously been

subject to some forestry activities in the past, as no old-growth or hollow trees were observed, with

one exception.

Two species of Eucalypt were present, Eucalyptus nitida the Western Peppermint which

predominated along the actual ridge and Eucalyptus obliqua the Stringybark which became the

dominant tree on the slopes, however the community generally fits within the definition of Eucalyptus

obliqua Wet Forest (undifferentiated) (WOU). The predominant species which were present in the

understorey were Manuka Leptospermum scoparium, Monotoca glauca and Bracken Pteridium

esculentum which would indicate a past history of firing. No species of threatened plants were

observed in this area.

One old-growth Eucalypt with significant hollows was observed at this recorded location.

GRID REF: 383391E – 5454354N (5m +/-)

As very few trees with hollows were observed during the survey this particular tree is important fauna

habitat. The individual hollows however did not appear to be large enough to accommodate a Masked

Owl nest site but could be suitable for Swift Parrots, although it is not a known nesting area for the

species. This area of forest and the associated creek-line would be suitable habitat for the White

(Grey) Goshawk. Area 4 should be excluded from future pit and quarry development.

AREA 5: Eastern area of the lease to the north and south of the access road and property entrance.

The forest vegetation along the eastern boundary of the lease area and on both sides of the access road

and entrance is comprised of a semi-mature stand of Eucalyptus brookeriana Wet Forest (WBR). This

community is listed as being vulnerable under the Tasmanian Nature Conservation Act 2002. The area

has been subject to forestry activities in the past and no old-growth trees were observed.

The main understorey species is the Dogwood Pomaderris apetala which formed dense and pure

stands in some locations and the Soft Treefern Dicksonia antarctica which was prevalent in the

depressions and gullys along with numerous ground ferns. A localized area of Leptospermum

scoparium Forest was noted in a shallow gully to the south of the access road and gate.

A localized infestation of Spear Thistle Cirsium vulgare was observed along the access road in the

vicinity of the entrance gate. Prompt attention to this patch of weed will ensure that it does not

continue to spread to cause management issues within the quarry.

On the basis of the presence of this threatened community this area of the lease should be treated as an

exclusion zone. It also forms a useful noise and visual buffer from the nearby private properties and

residences located along Elphinstone Road.

THREATENED VEGETATION COMMUNITIES:

One vegetation community listed under the Tasmanian Nature Conservation Act 2002 was present in

survey area No.5.

Eucalyptus brookeriana Wet Forest (WBR) was observed adjacent to the eastern boundary of the

main lease and to the north and south of the property entrance. The area of this community appears to

be outside of the gravel deposit and this patch of forest forms a valuable screen from private

properties and residences eastwards along Elphinstone Road. This area should be treated as an

exclusion zone and care should be taken to ensure that activities associated with the operations of the

quarry and pit does not impact on this area. The easement for the existing access road would not be

included in the exclusion zone.

VEGETATION COMMUNITIES OF CONSERVATION SIGNIFICANCE:

The areas of Acacia dealbata Forest (NAD) present along the creek-lines (sub-survey areas 2 and 3)

within the lease and within the wider locality is a locally significant area of this vegetation community

in its pure form. The community is also important for its intactness and good condition and for its

fauna habitat potential. The community extends further up the creek-lines than is shown on the Tas

Veg map. The drainage from the quarry and pit operations will need to be well managed to avoid

environmental impacts such as siltation and/or contamination on the creek-lines and on this vegetation

community.

THREATENED FLORA:

No plant species listed under the Tasmanian Threatened Species Conservation Act 1995 and/or the

Commonwealth Environment Protection and Biodiversity Conservation Act 1999 was observed or

recorded during the field survey.

None of the listed species known to have occurred previously within 5,000 metres of the study area

were observed during the field survey and no suitable habitat for any of these species was present in

the areas surveyed.

THREATENED FAUNA:

Tracks of Tasmania Devil Sarcophilus harrisii were observed in one location of the quarry which

confirms that the animal is present in the location, although other evidence of the species presence

such as scats was not observed. The Devil is present but probably in low numbers with the quarry and

environs forming part of a territory. No potential den sites were observed during the field survey.

No other species of threatened fauna listed under the above Acts and/or previously recorded from

within 5,000 metres of the site were observed during the survey.

THREATENED FAUNA HABITAT:

32 | P a g e

Alan Summers Transport Pty Ltd Extension of Operations – Oct 2012

Environmental Service and Design Pty Ltd – PAF#4561

The creek to the north of the current pit and quarry is a minor creek but with a permanent flow

directly into the Inglis River. No deep pools suitable as permanent habitat for the Giant Freshwater

Crayfish (Lobster) Astacopsis gouldi were observed however it is likely to be regularly used as

foraging habitat by adults of the species given the proximity to the Inglis River which is known to

have good numbers of the Crayfish (Lobster). The creek is however likely to be important habitat for

juvenile Astacopsis gouldi as they require small creeks and tributaries adjacent to major rivers in order

to avoid predation.

The proper management of run-off and drainage from the quarry and pit will be essential to order to

avoid siltation and possible contamination of the creek and impact on potential Astacopsis gouldii

habitat.

A single old-growth Eucalyptus obliqua, which had significant hollows was observed in sub-survey

area 5 near the southern boundary of the lease. Such trees are potential habitat for numerous species

of animals and birds including a number of threatened species. As few old-growth trees and trees with

hollows are present in the locality such individuals trees are important to retain. The tree is near the

southern boundary of the lease and is unlikely to be affected by future quarry extensions.

As the pit and quarry is located within a larger tract of state forest with good connectivity to extensive

areas of native forest and to the Inglis River the following threatened species of threatened fauna

would at times be present within the survey area. Suitable forest habitat for the White (Grey)

Goshawk was observed during the survey and the Spotted-tailed Quoll is also very likely to be

present. The Tasmanian Devil was confirmed during the survey.

No suitable habitat was observed in the survey area for the remaining threatened species which have

either been recorded previously from the wider area or could occur in the locality based on their

known geographical ranges, as referred to in the desktop survey section of this report.

ENVIRONMENTAL WEEDS:

The lease area including the active pit and quarry was almost completely free of environmental

weeds. The only weeds observed during the survey were Spear Thistle Cirsium vulgare along the

access road and adjacent to the main entrance gate. Prompt attention and follow-up treatment of this

Page 34: Environmental Effects Report Alan Summers Transport Pty ... Summers... · Prepared For: Allan Summers Transport Pty Ltd Version: Reviewed/Approved By Date Draft 1 Ian Ferris 01/042011

33 | P a g e

Environmental Service and Design Pty Ltd – PAF#4561

weed infestation will ensure that it does not spread into the active pit and quarry and result in weed

management issues.

Conclusions:

The proposed extension of the present gravel pit towards the north will not directly impact on any area

of significant vegetation or threatened fauna habitat. Any future extension of gravel extraction into

lease area 11M/2007 will also not directly impact on any area of significant vegetation or threatened

fauna habitat.

The vulnerable and threatened vegetation community Eucalyptus brookeriana Wet Forest was

observed in sub-survey area 5.

A single old-growth Eucalyptus obliqua with significant hollows was observed in sub-survey area 4,

near the southern boundary of the lease as significant fauna habitat.

No threatened species of plants were observed during the survey. Evidence of the presence of

Tasmanian Devils (tracks) was observed in one location during the survey. Sub-survey area 1.

Potential habitat for the threatened Freshwater Crayfish (lobster) was observed in the creek to the

north of the pit and quarry. Sub-survey area 2.

The most important issue to be addressed is the effective management of drainage from the pit and

gravel extraction operations in order to avoid siltation and/or contamination of the two creeks which

flow through and adjacent to the lease area, the northern creek being potential habitat for the

threatened Freshwater Crayfish (Lobster).

Only one minor infestation of the weed Spear Thistle Cirsium vulgare was observed during the

survey. No evidence was observed during the survey of the presence of the plant pathogen

Phytophthora cinnamomi.

Recommendations related to the proposed extension of the open pit at the existing quarry site

for vegetation and fauna habitat management:

EXTENSION TO EXTRACTION AREA:

Page 35: Environmental Effects Report Alan Summers Transport Pty ... Summers... · Prepared For: Allan Summers Transport Pty Ltd Version: Reviewed/Approved By Date Draft 1 Ian Ferris 01/042011

34 | P a g e

Alan Summers Transport Pty Ltd Extension of Operations – Oct 2012

Environmental Service and Design Pty Ltd – PAF#4561

Permit extension of the pit and quarry within lease area 45M/1975 towards the northern

boundary only to where vegetation has been recently cleared.

Future gravel extraction could be undertaken within lease area 11M/2007 without impacting

on significant vegetation or threatened fauna habitat.

Prepare and implement an effective drainage management plan for the pit and quarry

operation to ensure that there is no siltation or contamination of the creek-line to the north of

the site and of the creek-line to the south of both leases.

Prepare and implement a rehabilitation and revegetation plan for worked out sections of the

pit and quarry. Overburden and topsoil from the recently cleared area should be stripped prior

to the pit extension and utilised in the revegetation program.

VEGETATION COMMUNITIES:

The area of forest along the ridgeline in the southern 30% of the main lease should be

excluded from future pit extensions as it appears to have a limited gravel resource. As an area

of wet forest adjacent to creek-lines, it is potential habitat for the White (Grey) Goshawk.

The preparation and implementation of an effective drainage management plan will ensure

that there is no impact from siltation or contamination on the areas of Acacia dealbata Forest

(NAD) which extends along the two creeks that flow through and adjacent to the lease areas.

THREATENED VEGETATION COMMUNITIES:

The threatened vegetation community Eucalyptus brookeriana Wet Forest is present in the

eastern area of the main lease to the north and south of the access road and main entrance.

This area should be retained and treated as an exclusion zone and protected from any impacts

from the gravel extraction operations. The access road easement would not be included in the

exclusion zone. The retention of this area of forest would also provide a noise buffer and

visual screen from nearby properties and residences along Elphinstone Road.

THREATENED FLORA:

No species of threatened flora was observed or recorded during the field survey and no

specific action is required.

FLORA OF CONSERVATION SIGNIFICANCE:

No flora of specific conservation significance was observed during the survey and no action is

required in addition to the recommendations under vegetation communities.

THREATENED FAUNA:

Although no species of threatened fauna was observed during the survey, there was evidence

of the presence of Tasmanian Devil (tracks) however no den sites were found. No specific

action is required in addition to those under vegetation communities.

THREATENED FAUNA HABITAT:

The preparation and implementation of an effective drainage management plan will ensure

that there is no impact from siltation or contamination on the two creeks which flow through

and adjacent to the lease area. The northern creek in particular is potential habitat for the

Freshwater Crayfish (lobster).

The exclusion of the area of wet forest along the ridge in the southern 30% of the main lease

area from future quarry or pit extensions will retain potential habitat for the White (Grey)

Goshawk and the single old-growth tree with significant hollows on the lease.

ENVIRONMENTAL WEEDS:

An environmental weed management plan will be necessary to ensure that the present minor

infestation of the weed Spear Thistle Cirsium vulgare is contained and other weeds known to

favour disturbed sites such as gravel pits and quarrys do not become established during

quarrying operations.

PHYTOPHTHORA:

A Phytophthora Management plan should be prepared and implemented as part of the on-

going quarry and pit operations as a preventative measure.

Alan Summers Transport – Summers Sand and Gravel Pit

Weed Management and Hygiene Plan

Overview

PC Kay and D R Summers operate as Allan Summers Transport (TAS 21434B), which is a supplier of

screened and raw products (principally sand and gravel). All materials and processing will be sourced

and undertaken on site. The lease area including the active pit and quarry was almost completely free

of environmental weeds. The only weeds observed during the vegetation survey (2012) were Spear

Thistle Cirsium vulgare along the access road and adjacent to the main entrance gate. Prompt

attention and follow-up treatment of this weed infestation will ensure that it does not spread into the

active pit and quarry and result in weed management issues.

Objective

The objectives of the Weed Management & Hygiene Plan are;

1 To control existing weeds and to prevent further colonization by weeds at the site.

2 To allow optimum conditions for the establishment and eventual revegetation of the site

by native species.

3 Reducing the potential for the site being a source of weeds to neighboring or offsite

properties.

This will be achieved by the use of a specialist contractor who will spray the weeds every 6 months.

During this time the contractor will observe the success of the spraying regime and report this in the

register, as well as reporting observations and recommendations in the attached report. The site

hygiene procedures will prevent weeds spreading on site, and prevent weeds leaving site.

Weed Management and Mitigation

Current weed infection

A full vegetation assessment was conducted and weeds identified. Spear Thistle Cirsium

vulgare was identified and mapped above. No other weeds were identified on the site.

The potential impact of these weeds was assessed. It was concluded that they currently do not pose a significant risk, but should the weeds spread into the main area of the quarry, distribution of the weed would increase significantly. Hence the recommendation is to spray immediately and follow-up with the second application in six months, as per the Plan. The priority is obviously these weeds as they are the only weeds on the site. The strategy is to spray them. The use of an external, qualified weeds contractor will ensure that weeds will not spread and the existing weeds will be eradicated. The following register and weed report will be filled out every 6 month. Recommendations from the contractor will be implemented. This documentation will be available at the site and reported in the Annual Report. Eradication of the Spear Thistle will be monitored in the register. The register will also be used to detect the arrival of any new weeds. The Annual Report to EPA will detail any new weeds and the success of the Management Plan. The strategy as set out is to have the contractor spray every 6 months and sign off the register. The contractor will add additional sprays or additional spray rounds if weed numbers or species increase. This will be documented in the Weed Assessment Report (below). Spring and autumn are the optimum times for spraying, but weed varieties will determine this in the future. Identification of appropriate herbicides for control of future weeds, usage and effectiveness are not known at this stage. However, a qualified contractor will specify these parameters in the Weed Register and in the Weed Assessment Report; this will be reviewed 6 monthly. These variables will be determined by the weeds detected.

The General Plan is:

Maintain suitable records of the location of deliveries and source of any receivables.

Isolation of any area of known weed infestation until treatment has been undertaken, by

restricting access and vehicle movements through such areas.

Annual review of weeds and appropriate treatment of occurrences on the premises

including on site access roads and rehabilitation areas.

Provision of suitable resources, training and supervision for the undertaking of successful

weed treatments, including both chemical and physical methods.

Restrict site access by maintaining fenced perimeter and locked gate to control vehicle and

stock movements.

Dedicated offsite wash down facilities to undertake cleaning and maintenance of equipment

prior to access to the site, and upon leaving site.

Liaison and cooperation with external bodies in regional weed eradication programs,

including periodic review of weed management activities.

Site Operators and Contractor Training. Management and Control Measures will be

passed on to the operators. This is specifically associated with transport of machinery and

materials into and off site, and the cleaning procedures required.

Weed Hygiene Plan.

The Weed Hygiene Plan was compiled in conjunction with the Weed Management Plan. The hygiene plan is developed to ensure the development and associated works areas do not result in the introduction of newly declared weed species into the area, translocation of weeds within the development footprint, or the export of existing declared weeds out of the area.

All equipment accessing the site is washed offsite and clean of dirt and debris, following the guidelines of the Tasmanian Wash Down Guidelines for Weed & Disease Control (2004). The Summers Transport Site Manager will ensure that documented tracking will confirm this procedure is followed and the vehicles physical checked before access is given.

Vehicle, machinery and equipment hygiene (including the wash-down protocols when travelling between clean and contaminated areas within the development footprint) will be initiated following the guidelines of the Tasmanian Wash down Guidelines for Weed & Disease Control (2004). As there are no weeds detected within the work area this protocol will not initiated unless weeds are detected during the 6 monthly Weeds Assessment Report.

All equipment leaving the site will be washed clean of dirt and debris, following the guidelines of the Tasmanian Wash Down Guidelines for Weed & Disease Control (2004). As there are no weeds detected within the work area this protocol will not be initiated unless weeds are detected during the 6 monthly Weeds Assessment Report. The Summers Transport Site Manager will ensure that documented tracking will confirm this procedure is followed. Currently with no weeds in the active area of the quarry, washdown of equipment prior to leaving the site is not required (note offsite washing prior to entry to the site is required). Should weeds be detected in the active quarry area in the future, there is a designated wash down area near the first settling pond. Trucks would be washed of all site material into the bunded area. Runoff would be directed into the first settling pond to remove sediment from surface water. The runoff water would be managed and tested as required in the wastewater treatment section. The site manager will review the Weed Assessment Reports, and as required will log the introduction of wash-down procedures should they need to be initiated. A daily log sheet will be completed as part of the site entry process to record each truck and the adherence to the hygiene protocol. Documentation will be kept on site for review as required. The above procedures will ensure that no materials contaminated with weed propagules (seed, propagative vegetative material) are either imported into the development footprint or exported out of those areas.

Alan Summers Transport – Summers Sand and Gravel Pit

Phytophthora Management Plan

Overview

PC Kay and D R Summers operate as Allan Summers Transport (TAS 21434B), which is a supplier of

screened and raw products (principally sand and gravel). All materials and processing are sourced and

undertaken on site.

The presence Phytophthora has not been identified in the operational area of the lease. The receipt of

materials from other locations, and periodic use of equipment from other locations presents the risk of

introduction of Phytophthora to the area.

Objectives

The purpose of this Management Plan is to minimize the risk of diseases (and weeds) being brought

into the area, dispersed throughout the site, or re-transported to adjacent areas, by employing good

hygiene management at the sites. DPIWE’s Interim Phytophthora cinnamomi Management

Guidelines; The Quarry Code of Practice; and the Tasmanian Wash Down Guidelines for Weed &

Disease Control have been consulted in developing management prescriptions.

Management and mitigation

Where possible use materials sourced in situ and do not allow external materials to be utilised

in site operation or remediation.

Avoid ponding of water other than for sediment retention purposes.

Confine mobile equipment used on other sites to dedicated traffic routes.

Ensure all equipment accessing the site is washed offsite and clean of dirt and debris,

following the guidelines of the Tasmanian Wash down Guidelines for Weed & Disease

Control (2004).

Restrict site access by keeping gate locked when not in attendance. Other access is not

controllable.

Periodic review of activities with regulator.

Other

If equipment has been used or accessed in a known area affected by Phytophthora cinnamomi the

equipment is to be cleaned using Phytoclean™. This is registered for the sterilisation of equipment

and machinery in Tasmania for the control of Phytophthora cinnamomi. It is used at a rate of 200 mL

per 10 L of water for washing surfaces cleaned of mud.

Solution should remain in contact with surfaces for at least 30 seconds before rinsing. It is available in

20 L or 200 L drums and is manufactured by Avis Chemicals, Dandenong (Ph: 03 9794 5585, fax 03

9706 9206). Use only in accordance with the label directions and when prescribed in the job

specifications for the control of Phytophthora root rot.

MINING PLAN

1. Site Geology

The geology of the deposit comprises unconsolidated Tertiary river sediments, partly overlain by

Tertiary basalts, and underlain by Precambrian schists. The river sediments are rounded quartzitic

gravels and quartz sands. A general discussion of the extraction of materials from this area is found in.

McKibben J and Matthews W. L., “Resource assessment: The Calder–Flowerdale gravel pits”,

Tasmanian Geological Survey Record 1996/11.

The deposit has been explored using excavator test pits. The exploration revealed that the deposit is

highly variable in depth of material, and particle size distribution. This is typical of less mature fluvial

deposits, and is considered beneficial as a greater number of material types can be supplied, but it

means that the lateral site disturbance potential is difficult to minimise. The MRT-mapped extent of

the deposit covers most of the leased area.

2. Current activity

2.1. Extraction Process The site operates at a low level of production, producing various grades of material as demand

requires. The sand/gravel is extracted by an excavator. No blasting is required. The sand/gravel is

screened to provide a variety of products for use in construction and agriculture

Depending on the client demand, the source of within the pit area varies, as the proportions of

coarse/fine sand, with or without gravel, vary considerably.

No changes are proposed to this process for the proposed higher level of production.

2.2. Top Soil and Overburden Overburden materials (and topsoil separately) are excavated and removed to stockpile areas. Some of

the material is stored on the excavation boundary and vegetation allowed to colonise the stockpiles.

Stockpiles then assist in attenuating noise, dust and potential visual impacts. New stockpile are

developed as appropriate to provide for rehabilitation of the proposed expanded production. Materials

not needed for attenuation will be recycled as per current practice.

Over much of the site, the upper layer is material not previously mined, but with topsoil removed.

3. Runoff

All issue points are controlled by drains and fed through silt traps to ensure that runoff is of

satisfactory quality. Silt traps are temporary, and are installed as required to ensure that silt from

drainage does not leave the site. Drainage pathways (refer Figure 1) alter as material is extracted and

the surface drainage regime changes.

Figure 1. Drain lines

3.1 Maintenance

Silt traps will be cleaned as necessary. Fines are returned to the pit area.

3.2 Silt Trap Construction

Silt traps are generally constructed as per Figure 2.

Figure 2. Silt trap construction

Construction comprises:

a. Consider safety in siting silt traps to prevent inadvertent access.

b. Excavate a pit ~2m wide, ~5m long, ~1.5m deep (ramped at one end) at the lowest end of the extraction area.

c. Angle sides appropriate to the soil type, install berms either side as necessary. Topsoil or gravel any berms as required to limit erosion. Geotextile may be found useful as a liner in softer soils.

d. Excavate a 250mm (max) deep shelf at the outlet end as a vegetated filter area

e. Shovel some topsoil onto the veg-filter area. Plant swamp grasses, sedges etc as required (plants will grow there anyway, in time)

f. Direct all runoff through this pit, by drains, berms, etc.

It may not be possible or practical to construct silt traps to precise dimensions or shapes.

4. Extraction Areas

The plans below (Figures 3 - 5) indicate the areas in which extraction will be concentrated, over the

remaining lifetime of the pit. Area 1 is largely complete, with several areas being worked on

simultaneously. Development of Area 2 is underway, and development in Area 3 has not commenced.

It is important to understand that specific locations may not be utilised until the demand for the

particular material encountered in that area necessitates extraction. Subsequently, some areas may not

be rehabilitated until reserved are extracted. Some areas not planned for extraction are of poor quality,

or have been mined out previously.

Assuming that economic conditions remain as at present, Area 3 should not be required until Areas 1

and 2 are completed. Part of Area 1 shall remain as treatment and stockpile area.

4.1. Constraints

The limits to the extraction zones are determined by a combination of factors, some of which

overlap (Figure 6). An area of high conservation value vegetation (E. brookeriana) is present on

the central eastern side of the main lease, and is also not underlain by extractable sand or gravel.

The southeast corner of the lease has poor reserves of material, and the central west area is a steep

sided creekline. The northern boundary is steep and also has drainage lines, and poor reserves.

All drainage lines are avoided, for protection of possible A. gouldi habitat, steep terrain and no

gravel reserves. 9M 1999 is a Waratah Wynyard Council Lease. No extraction will occur near this

lease, but revegetation will occur and so to prevent accidently revegetating this lease, survey pegs

will be put in prior to revegetating in this area.

Figure 6: Mining areas showing constraints.

5. Rehabilitation

During operation topsoil stockpiles will be placed near the boundaries of the extraction areas.

The vegetation that may establish on the outside of the stockpiles will be maintained, to provide

suitable visual screens.

Progressive rehabilitation will occur as sand extraction from each area of the pit is completed.

Page 62: Environmental Effects Report Alan Summers Transport Pty ... Summers... · Prepared For: Allan Summers Transport Pty Ltd Version: Reviewed/Approved By Date Draft 1 Ian Ferris 01/042011

61 | P a g e

Alan Summers Transport Pty Ltd Extension of Operations – Oct 2012

Environmental Service and Design Pty Ltd – PAF#4561

As the site has been operated previously (by others) there remain areas which require

rehabilitation. These will be progressively rehabilitated during the life of the pit. Natural

regrowth is occurring, although damage from trespassers occurs commonly.

Species used for revegetation will be native species found in the Calder region.

Native vegetation at this site may be placed on the steeper slopes. Planting tube stock or plugs

will aid in rapid colonisation of the vegetation thus reducing the potential for erosion and loss of

the topsoil layer. All species shall be sourced locally from a reputable native plant specialist, 1.5

plants per m2 would be required.

6. Erosion Control

The surface material is generally prone to erosion following removal of vegetation. However the

site has a number of natural sumps where the suspended fines (a small proportion of the bulk

material) settle quickly. Existing steeper slopes have not been impacted by the previous extraction

operations, and are not proposed to be affected by this proposal, as the sand/gravel reserves are

not present on steeper slopes. The lower levels of the deposit are slightly cemented and are not as

prone to erosion.

Erosion can be managed by controlling velocity of runoff, and vegetative cover; thus steeper

slopes without vegetation may erode. As the site is relatively flat, erosion in minimal, and as

there are no reserves on steeper slopes, erosion is not considered of major significance to the

extraction operations. Silty runoff is controlled by silt traps as above (Sect 3).
