FOREWORD

FUNCTION OF THE ENVIRONMENTAL EFFECTS AND PLANNING REPORT

The Environmental Effects and Planning Report (EEPR) has been prepared to support a development application made by Mr Robert Morey (obo The Trustee for Flexmore Park Trust) for a Planning Permit to continue the extraction of sands on Flexmore Park at Penna.

This application seeks approval for production levels of up to 20,000 cubic metres per annum. Annual production will not exceed 20,000 cubic metres per annum (equates to approximately 32,000 tonnes based on a conversion factor of 1.6 tonnes per cubic metre of extracted/screened sand).

The activity is Level 2 activity defined within Schedule 2 of the Environmental Management and Pollution Control Act 1994 (Tas) (EMPCA). Level 2 Activities must be referred by the planning authority (in this case, Sorell Council) and to the Environment Protection Authority (the EPA), for assessment under EMPCA.

This EEPR provides information on –

1. the present environment of the sand extraction activity, including such matters as zoning (planning scheme), land use, flora, soils and climate. It also describes the operation in detail and potential emissions sources; and

2. each of the potential environmental issues associated with the sand extraction activity and provides detail regarding the mitigation measures that are undertaken to address each issue.

ROLES IN THE APPROVAL PROCESS

The EPA will use the EEPR to assess the activity in accordance with the Environmental Impact Assessment Principles provided in S74 of EMPCA. The EEPR may be referred to other relevant State agencies as part of this process to seek comments in relation to the proposed development. The EPA assessment may generate environmental conditions that would be included in the Planning Permit if one is issued by Council. The Council will use the EEPR as the basis for assessing the development application and for drafting conditions under which a Permit may be granted.

STATUTORY RIGHTS OF ANY PERSON TO MAKE REPRESENTATIONS

When the EPA is satisfied that sufficient information regarding the proposed development has been received, the Director will provide written notice to the Council to advertise the application. The Council will advertise the application for a period within which anyone can make a representation about the project. Representations should be directed to the Sorell Council.

Sorell Council

47 Cole Street (PO Box 126)

SORELL TAS 7172

When the representation period has closed, the Council will forward all representations to the EPA, which will complete the assessment of the environmental aspects of the project. The EPA takes into consideration the representations and the comments received from other State agencies to which the EEPR was referred. An addendum or ‘supplement’ to the EEPR may be required of the project proponent to respond to representations and comments from referral agencies.

When the EPA has made its decision about environmental aspects of the development it advises Council of its decision, which may include specific conditions that relate to environmental management and mitigation measures. Council then determines whether a Planning Permit will be issued. Following the decision of Council, the proponent and those members of the pubic whom made a representation have 14 days to appeal the decision of issuing a Planning Permit to the Resource Management and Planning Appeals Tribunal.

PART A ‐ BACKGROUND INFORMATION

The Flexmore Park Sand Extraction Areas are located on private freehold land at 716 Shark Point Road Penna in the Sorell Municipality (Figure A‐1).

A.1 CURRENT ACTIVITY

The activity has a permit to extract up to 4,999 cubic metres per annum. Extraction levels in recent years have been up to 20,000 cubic metres per annum. This includes the extraction of sand and sandy topsoil.

This application brings the activity (ie extraction of up to 20,000 cubic metres per annum) into conformance with the Scheme by seeking approval for the maximum current production level, being 20,000 cubic metres per annum.

A.2 PROPOSED ACTIVITY

The Land for the purposes of this application is that area geographically covered by Mining Lease 1297P/M (Figure A‐2A) and further delineated by the spatial layer described as ‘The Land’ in Figure A2‐A.

The approximate proposed location of the extractive areas for the next 5 years (2019 – 2023 – this reflects the Mine Plan submitted to and approved by Mineral Resources Tasmania) is shown in Figure B2 with the full extent of The Land (within which sand extraction may occur at some stage in the life of the activity) shown in Figure A‐2B. The 5‐year extraction locations are simply shown here in this application as examples of the localised and discrete patches within which sand and sandy products may be extracted within The Land.

To remove any doubt, this application seeks approval to extract sands and sandy products from anywhere within that geographic area described as ‘The Land’ in Figure A‐2A. The supporting information contained here addresses the requirements of the Scheme on this basis.

The use and development will include the following activities, which are currently occurring:

surface site preparation by removing the shallow sandy topsoil;

excavation of in situ sands and loading into truck for transport to the storage and handling area;

stockpiling and screening of sands in the storage and handling area;

loading trucks with sands using a wheel loader in the storage and handling area; and the

transport of materials by truck with/without trailer.

Annual production will not exceed 20,000 cubic metres per annum (this equates to approximately 32,000 tonnes based on a conversion factor of 1.6 tonnes per cubic metre of extracted/screened sand).

A.6 RATIONAL AND ALTERNATIVES

Sand extraction commenced in 1987 with a DA approved by Municipality of Richmond and a Mining Lease Number 1297P/M established over 400 ha by the then Mines Department. The then Department of the Environment required a basic environmental impact document but not a license to operate.

A.6.1 Sand Resource

The farm is based on an eight‐ metre‐high terrace of Tertiary sediments overlooking the Pitt Water estuary,

with a range of hills to the east composed of Triassic sandstone and Jurassic dolerite (Duncan 19991). The

western side of the Mining Lease is generally of low relief (see Figure A‐2B) with the eastern side rising upwards to form the Mt Lord section of the Pontos Hills. The low relief areas are comprised of dune systems which can be visually identified using 1 m contours, as depicted in Figure A‐2C.

Over 50% of the sand is used for mortar, another 25% is sharp sand and the remainder is used for top dressing

loam. Blending of sharp and fat sand during screening produces mortar sand and bedding sand for laying

under concrete slabs or pipes.

Duncan (19991) provides the following descriptions about the resource ‐

The farm area is underlain by 6 to 7 metres of Tertiary clayey sand and clay overlain by 1–2 metres of assorted sand. The overlying sand in the larger northern area is a combination of residual brown or hardpan layers or yellow windblown drifts collecting around the lee of isolated hills or in low NNW‐trending ridges. The aeolian component increases to the south where it is expressed as 1–2 metres of sharp, white to light brown sand in the sand pit overlying clayey sand or as a low one metre high coastal platform of white fine‐grained sand just above water level in the lee of the bluffs….

The extent and thickness of the clayey sand at Flexmore Park appears to be unusual for Tertiary sediments in southern Tasmania, where the dominant lithology is clay. This sand has been deposited in the fault trough of the Coal River Valley, probably in an estuary (Leaman, 1971). The sand was mainly derived from erosion of Triassic sandstone and transported seawards by the ancestral Coal River and perhaps added to by local creeks from the extensive sandstone ridges of Mt Lord to the east.

Subsequently, during the lower sea levels of Quaternary glacial times, the overlying sharp sand was blown up from the exposed Coal River bed by north‐westerly winds to accumulate in the lee of ridges, valleys and bluffs, for example in the southern part of the current lease. As the clayey sand was

leached and dried out, this produced sharp sand which blew downwind and added to the southern deposits, a process which is continuing today.

A.6.2 Resource significance

Sand resources of the quality and quantity that can be utilised as an extractive industry, like that of Flexmore Park, are rare around Hobart (Matthews and Donaldson 19942, Duncan 19993). Many have been zoned or reserved as a land use class that excludes mineral extraction or they have become sterilised (in part or entirely) through the encroachment of residential use (ie. sensitive developments). This resource is of critical importance to the ongoing supply of high quality, reasonably priced sand to the southern region of Tasmania.

A.6.3 Successful coexistence of agriculture and sand extraction

Flexmore Park is a coastal agricultural enterprise where the soils are predominantly comprised of sands or sandy loams. The topsoil is leached and nutrient poor in its natural unimproved state. Areas of deep sands are generally of aeolian (windblown) origin, evidenced by the broad dune landforms which occur on the property (some have been removed by the sand extraction process). Slopes on the eastern side of the property support sandy to clay soils ‐ they overlay dolerite derived sediments (talus in parts) with alluvial deposits in gullies.

Land capability has been mapped as Class 5 and 6 for most of the property (Figure D‐5) with some areas of Class 4 mapped on better dolerite derived – clay loam soils. The Class 5 and 6 units overlap with areas to be sand extracted as shown in Figure D‐5.

On Flexmore Park, significant farm improvements have been made concurrent to the act of extracting sands for sale into the construction and landscape/horticultural sectors. These include the below –

Establishment of farm water storage basins and channels for drainage and water harvesting

Few potential water storage sites exist on the property where low cost conventional dam wall construction can provide affordable capacity. Ability to remove merchantable materials from water storage sites both help fund earth moving costs and greatly increases capacity on marginal sites.

Improvements to topographic landforms for irrigation and cropping

Land levelling of sand hills to provide improved topography for more efficient farming operations and enhance land capability.

Enabling broad scale irrigation area development. Difficult topography of steep sand ridges fragment irrigation areas if not removed.

To spread and level sand hills and ridges, rather than remove, contaminate otherwise more productive surrounding land, creating an increased erodible area.

Under progressive management the development of the farm has the potential to continue at a manageable and sustainable pace. The property location favours the integration of farm development with sand extraction due to proximity to a market for sand (ie lower transport costs) but benefits from its relative isolation by a long boundary with Pittwater, Pontos Hills to the east and the absence of public road frontages and residential developments.

A.7 CLIMATE

The nearest Bureau of Meteorology weather recording station is at Hobart Airport to the south of the development site.

The station details for the Hobart Airport weather station are ‐

Site number: 094008

Latitude: 42.83 °S Longitude: 147.50 °E

Elevation: 4 m

The development and use occur in a region with cool winters and warm summers (Graph 1), with a slight increased chance of higher precipitation occurring in the winter and spring period (Graph 2). Large rainfall events can occur in summer where they are associated with thunderstorm activity or low‐pressure systems that direct precipitation onto the south‐east coastline of Tasmania.

The below wind roses indicate that winds during the morning are generally north‐westerly, with minor contributions from the north and west. Warm to hot north‐westerly winds can occur in the summer months and are often associated with thunderstorm and heavy rain activity. South‐easterly sea breezes, which can be strong, characterise the afternoon and evening period, especially during summer. South‐easterly winds can be strong during low‐pressure systems that direct air flow onto the south‐east coast.

A.8 LAND CAPABILITY

Land capability has been mapped as Class 5 and 6 for most of the property (Figure D‐5) with some areas of Class 4 mapped on better dolerite derived – clay loam soils. The Class 5 and 6 units overlap with areas to be sand extracted as shown in Figure D‐5.

A.9 FLORA AND FAUNA

An ecological assessment was made of the site for threatened flora, fauna or ecological communities.

A.9.1 Vegetation

The vegetation mapped by TASVEG for the Mining Lease is shown in Figure D‐7. No threatened native vegetation has been mapped within The Land. TASVEG have mapped Eucalyptus viminalis forest on The Land however this is not present, the forest is pasture grass with intermittent canopy trees and plantation (mainly pine).

Remnant trees of Eucalyptus viminalis and E. amygdalina occur on dry sandy banks.

The understorey is dominated by pasture herbs, grasses and weeds.


16

Pine (Pinus radiata) plantation shelterbelts occur across the property.

A.9.2 Threatened Flora Species

No threatened flora species have been recorded in the Mining Lease (see Figure D‐8) based on the Natural Values Atlas (a DPIPWE maintained database of natural values). None were observed during the assessment made on 28 September and 18 November 2017. The survey focused on those areas the subject of short‐term extraction stages and of those areas where extraction was likely to occur in the next decade or so. Shelterbelts were also assessed to determine if any ‘weedy’ native species of conservation significance were present, such as Lepidium hyssopifolium and Vittadinia species.

No threatened flora species were observed during the surveys of 28 September and 18 November 2017.

A.9.3 Weeds

Declared weeds observed within the Mining Lease during the 28 September and 18 November 2017 surveys include Californian thistle and boxthorn (Figure D‐9). Like any agricultural environment there will be weeds present, such as pasture‐based weeds like spear and variegated thistles.

A.9.4 Threatened Fauna Species

Several threatened fauna species (terrestrial and marine) have been recorded in the region around the Mining Lease (Figure D‐10) based on the Natural Values Atlas.

There are no wedge‐tailed eagle or white‐bellied sea eagle nests known to occur within 1km of The Land.

Flexmore Park is an agricultural property where the native vegetation was cleared decades ago and land worked for the benefit of agricultural production – cropping, grazing, orchards etc. Soil is being frequently tilled irrespective of the sand extraction activity. Not surprisingly therefore, no mammal dens or other threatened fauna species were recorded within The Land during site surveys conducted on 28 September and 18 November 2017.


17

A.10 WATERCOURSES

The drainage from the stockpile and handling area is shown in Figure B‐3, with regional drainage and

catchments shown in Figure D‐6.

The stockpile and handling area are sloped towards the sediment pond as too are the drains that direct water

to it, as shown in Figure B‐3. The sediment pond is about 1Ml capacity and receives occasional water from a

natural drainage line that originates off the property. It is fitted with a drainage pipe which flows into an

existing channel from which the water can be pumped to irrigation areas.

Farm water management ensures runoff is retained and does not reach Pittwater. There are three major

water storages on the farm with a combined capacity of 400 ML, used for irrigation and stock water.

Occasional runoff from the higher dolerite hills to the east of the mining lease is harvested and diverted by a

1.5 km of contour channel (existing) into storage for future use as outlined above.

Water drainage from localised areas of sand extraction has not been shown because these areas are never

subject to external flows, due to the diversions as outlined above. The inherent natural drainage of the deep

sand profile easily copes with typical rainfall events the area receives. Minor sediment movement is readily

captured by pasture surrounding the extraction areas.

PART B ‐ PROJECT DESCRIPTION

B.1 DEVELOPMENT OVERVIEW

The application is to seek approval (retrospective) for the extraction of up to 20,000 cubic metres from the areas of farm development on Flexmore Park, Shark Point Road Penna.

The Land for the purposes of this application is that area geographically covered by Mining Lease 1297P/M (Figure A‐2A) and further delineated by the spatial layer described as ‘The Land’ in Figure A2‐A. Coordinates for The Land are in Attachment 4.

The approximate proposed location of the extractive areas for the next 5 years (2019 – 2023 – this reflects the Mine Plan submitted to and approved by Mineral Resources Tasmania) is shown in Figure B2 with the full extent of The Land (within which sand extraction may occur at some stage in the life of the activity) shown in Figure A‐2B. The 5‐year extraction locations are simply shown here in this application as examples of the localised and discrete patches within which sand and sandy products may be extracted within The Land.

B.1.1 Volume extracted and processed

Annual production will not exceed 20,000 cubic metres per annum, including sand and sandy topsoil products. The volume equates to approximately 32,000 tonnes based on a conversion factor of 1.6 tonnes per cubic metre of extracted sand. The full 20,000 cubic metres per annum may be mechanically screened at the storage and handling area shown in Figures B‐2 and B‐3 to remove any clumps of clay, rocks and coarse vegetative debris (roots).

B.1.2 Extraction methods

The use and development will include the following activities, which are currently occurring:

surface site preparation by removing the shallow sandy topsoil;

excavation of in situ sands and loading into truck for transport to the storage and handling area;

stockpiling and screening of sands in the storage and handling area;

loading trucks with sands using a wheel loader in the storage and handling area; and the

transport of materials by truck with/without trailer.

B.1.3 Topsoil stripping, removal and land rehabilitation

There is a shallow topsoil (overburden) of 0.3 m depth (on average) on the sands subject to extraction. It has a very weak natural structure and almost no colloid content. Therefore, it is highly erodible, especially when disturbed by either mining and standard agricultural tillage activities. It is also of very low agricultural potential in its natural state.

The topsoil in the areas where sand extraction would occur under this application ‐

1. is naturally hydrophobic,

2. has no ability to form a structural crust,

3. has very little ability to hold water or nutrients that are necessary to support large populations of macro or micro soil life, and

4. has low ability to support agricultural production in its natural state.

Currently, and for the past 20 years, the ‘topsoil’ has been taken to the storage and handling area and screened to remove roots and other coarse debris and placed into a stockpile. It is sold as a landscaping – horticultural product. The removal of sand deposits produces a more level topography with a less erodible clay/sand mix, better able to retain water and nutrients, upon which to rebuild new fertility for agricultural use.


23

As background to the Quarry Code of Practice (2017) suggested approach to the use of topsoil, it provides under clause 7.7.1 ‐

‘Topsoil is usually the darker, upper soil layers. Though only 10 ‐ 30 cm deep, it contains nutrients, minerals, seed, and organic matter which help to bind it all together. A thin layer of topsoil can support a forest and protect the subsoil from erosion. The regenerative capacity of the natural soil should be protected during the opening up of new areas at quarries.’

The Quarry Code of Practice does however state on page 6 (emphasis added) ‐

‘The code comprises elements for both the proposed use and development of land for extractive purposes as well as ongoing environmental management.

The sections of the code are not in themselves legally enforceable. They are intended to encourage operators to achieve good environmental performance without the need to resort to legislative enforcement mechanisms.

The provisions of the code can be enforced as Permit conditions, or by issuing Environment Protection Notices. If necessary, an Environment Protection Notice may be used to vary the conditions on an existing Permit.

While the code outlines acceptable standards, it is important to note that where an operator is able to demonstrate that the potential environmental impacts can be managed by other means to the satisfaction of the approval authority, appropriate site‐specific conditions for the operation should be applied in the Permit.’

The stockpiling of ‘topsoil’, as suggested by clause 7.7.1 of the Quarry Code of Practice, could have a major impact on areas downwind due to erosion and would increase the area of disturbance required (ie. there would be a need to stockpile the topsoil adjacent to the extract areas rather than simply hauling it away to the storage area). Both situations can be avoided by the removal of the ‘topsoil’ which is not needed to achieve the successful rehabilitation of the agricultural land.

The subsurface layers, which become the new growing medium, used to rehabilitate the extraction sites, have a naturally higher clay content, is non‐hydrophobic, will form a stable crust to prevent erosion and has substantially higher water and nutrient holding capacity. It is then possible to grow vegetation which readily increases the soil organic matter content.

Site rehabilitation is achieved by –

Spreading of farm sourced clay to stabilise the new topography following sand hill removal;

Spreading of Bio‐solids to build new fertility on exposed subsoils;

Establishment of pastures and associated vegetation (eg clovers, lucerne) to improve soil carbon content and fertility (eg nitrogen fixing bacteria).

B.2 MINING LEASE

A Mining Lease (1297P/M), depicted in Figures A‐2a and A‐2b, is in force. The geology of the Mining Lease is predominantly Quaternary sands (Figure D‐4) (see A.6.1 SAND RESOURCE for more details).

B.3 PROCESS EQUIPMENT

B.3.1 Sand extraction

The current equipment (see Plate 2) used for sand extraction is: Excavator: Zaxis 200, Dump Truck: Hitachi AH250. As new machinery becomes available, or old machinery needs to be replaced, the make and model numbers will change as is the case for any extractive activity.

B.3.2 Handling and stockpiling

The current equipment (see Plate 3) used for handling and stockpiling is: Screens: Scorpion x 2 (including hopper and grizzly). The Dump Truck and Excavator shown in Plate 2 are used at the storage and handling area to move sand between stockpiles. The Excavator shown in Plate 2 is used to load delivery trucks. As new machinery becomes available, or old machinery needs to be replaced, the make and model numbers will change as is the case for any extractive activity.

B.4 ACCESS

The Mining Lease is accessed from Shark Point Road (Figures B‐1 and D‐2). There is quick and efficient access from the activity to Shark Point Road which is managed and maintained by the Sorell Council. Shark Point Road is a no through road, it terminates at private land in ownership of Mr Robert Morey (the owner of the land upon which the Mining Leases is located).

Shark Point Road continues eastward to intersect with Penna Road, and then further east it intersects with the Tasman Highway, north of Sorell.

The surface of the access road is gravel. The access is sufficiently wide for trucks and other vehicles to pass without interference to each other or others whom may be using the road network.

B.5 OPERATIONAL AREA PLANS

B.5.1 Proposed Layout

The Land for the purposes of this application is that area geographically covered by Mining Lease 1297P/M (Figure 2A). The coordinates for The Land are in Attachment 4.

The approximate proposed layout of the extractive areas for the next 5 years (2019 ‐ 2023) is shown in Figure B2 with the full extent of The Land (within which sand extraction may occur at some stage in the life of the activity) shown in Figure A‐2B.

Cross‐sections of extraction areas have not been provided as they are not particularly informative of the activity given the sand removal is shallow – about 2 to 3 metres – and localised.

Infrastructure

The existing access road provides the only route from Shark Point Road into the Mining Lease (Figure B‐2). The activity, including car parking area, extraction of sand and storage/handling of sand is contained within the Mining Lease. No new roads or hardstands are required for the activity as these were already established for the existing activity or as part of farm management (eg internal farm roads – Figure B‐2).

Stockpiles

Merchantable products are stockpiled in the storage and handling area (see Figures B‐2 and B‐3).

Loading for deliveries

Loading of trucks with merchantable product occurs in the storage and handling area (Figure B‐3).

Drainage

Drainage from the storage and handling area is managed by the existing drains, bunding and

sediment pond as depicted within Figure B‐3. The overflow discharges to an existing channel from

which water can be pumped to irrigation areas. The sediment pond is approximately 1Ml, enough

to capture and treat water (for sediment removal) prior to discharge. Sediment accumulation rates

in the sediment pond are monitored and recovered as required.

B.5.2 Extraction Staging Plan

The areas of extraction over the next 5 years or so, subject to extraction rates achieved per annum (noting the limit is 20,000 cubic metres per annum), are shown in Figures B‐2 and D‐3 – this reflects the Mine Plan submitted to and approved by Mineral Resources Tasmania. As the ML is renewed over time the Mine Plan will be updated, as required by the Mineral Resources Development Act 1995, with areas of extraction occurring within the area identified as The Land.

The full extent of The Land – the area within which sand extraction may occur at some stage in the life of the activity ‐ is shown in Figure A‐2B. The 5‐year extraction locations are simply shown here in this application as examples of the localised and discrete patches within which sand and sandy products may be extracted within The Land.

PART C – BACKGROUND OF ACTIVITY AREA

C.1 CATEGORISATION OF USE/DEVELOPMENT

The development and use is consistent with the definition of Extractive Industry –

‘… use of land for extracting or removing material from the ground, other than Resource development, and includes the treatment or processing of those materials by crushing, grinding, milling or screening on, or adjoining the land from which it is extracted. Examples include mining, quarrying, and sand mining.’

C.2 ZONING AND OVERLAYS

The use and development occur within the Sorell Municipality (Figure C‐1). An extractive pit activity is defined as an Extractive Industry in the Sorell Interim Planning Scheme 2015 which is a Discretionary use within the Rural Resource zone.

All land immediately adjoining The Land is zoned Rural Resource (Figure C‐2).

The Mining Lease intersects with several Overlays, including the

Coastal Erosion Hazard (Figure C‐3a);

Coastal inundation Hazard (Figure C‐3b);

Landslide Hazard and Attenuation Area (Figure C‐3c);

Potential acid sulphate soils (Figure C‐3d);

Potential dispersive soils (Figure C‐3e);

Scenic landscape area (Figure C‐3f); and

Waterway and Coastal Protection Area (Figure C‐3g).

C.3 DETERMINING THE APPLICATION

The planning authority has discretion, pursuant to the Scheme, to refuse or permit a use or development if:

(a) the use is within a use class specified in the applicable Use Table as being a use which is discretionary;

(b) the use or development complies with each applicable standard but relies upon a performance criterion to do so; or

(c) it is discretionary under any other provision of the planning scheme, and the use or development is not prohibited under any other provision of the planning scheme.

In determining an application for any permit the planning authority must, in addition to the matters required by ss51(2) of the Act, take into consideration:

(a) all applicable standards and requirements in this planning scheme; and

(b) any representations received pursuant to and in conformity with ss57(5) of the Act, but in the case of the exercise of discretion, only insofar as each such matter is relevant to the particular discretion being exercised.

In determining an application for a permit for a discretionary use the planning authority must, in addition to the matters referred to in subclause 8.10.1 of the Scheme, have regard to:

(a) the purpose of the applicable zone;

(b) any relevant local area objective or desired future character statement for the applicable zone;

(c) the purpose of any applicable code; and


35

(d) the purpose of any applicable specific area plan but only insofar as each such purpose is relevant to the particular discretion being exercised.

In determining an application for any permit the planning authority must not take into consideration matters referred to in clauses 2.0 and 3.0 of the Scheme.

C.4 ZONE USE STANDARDS

The following notes and comments are made about each Use Standard relevant to the development. The numbers used to label each table below is the same as for the Scheme.

26.3.3 Sensitive Use (including residential use)

Not relevant to this activity.

26.3.2 Visitor Accommodation

Not relevant to this activity.

26.3.3 Discretionary Use

Objective ‐ To ensure that discretionary non‐agricultural uses do not unreasonably confine or restrain the agricultural use of agricultural land.

Performance Criterion (P) Comments

P1

A discretionary non‐agricultural use must not conflict with or fetter agricultural use on the site or adjoining land having regard to all of the following:

(a) the characteristics of the proposed non‐agricultural use;

(b) the characteristics of the existing or likely agricultural use;

(c) setback to site boundaries and separation distance between the proposed non‐agricultural use and existing or likely agricultural use;

(d) any characteristics of the site and adjoining land that would buffer the proposed non‐agricultural use from the adverse impacts on amenity from existing or likely agricultural use.

Development complies with P1.

The sand extraction activity operates harmoniously with agricultural uses on the property (covered by the Mining Lease) and in the remainder of the landscape.

The QCP has been considered and its operational standards will be applied for the Level 2 activity – this includes the management of dust and noise.

The extraction activity will not fetter the use/development of adjoining agricultural land outside the operational area for an agricultural use. Currently the land is used for stock grazing, orchards and some cropping.

C.5 ZONE DEVELOPMENT STANDARDS

The following notes and comments are made about each Development Standard relative to the development and use.

26.4.1 Building Height

Objective – To ensure that building height contributes positively to the rural landscape and does not result in unreasonable impact on residential amenity of land.

Van Diemen

Van Diemen


38

Development Standard is not relevant to this activity – no buildings are proposed.

26.4.2 Setback

Objective – To minimise land use conflict and fettering of use of rural land from residential use, maintain desirable characteristics of the rural landscape and protect environmental values in adjoining land zoned Environmental Management.

Acceptable Solution (A) Comments

A1

Building setback from frontage must be no less than:

20 m.

Complies.

No buildings are proposed.

A2

Building setback from side and rear boundaries must be no less than:

50 m.

Complies.


A3

Building setback for buildings for sensitive use must comply with all of the following:

(a) be sufficient to provide a separation distance from a plantation forest, Private Timber Reserve or State Forest of 100 m;

(b) be sufficient to provide a separation distance from land zoned Significant Agriculture of 200 m.

Complies.


A4

Buildings and works must be setback from land zoned Environmental Management no less than:

(a) 100 m.

Complies.


Works will occur further than 100m from any land zoned Environmental Management (see Figure C‐2).

26.4.3 Design

Objective ‐ To ensure that the location and appearance of buildings and works minimises adverse impact on the rural landscape.

Performance Criterion (P) OR

Acceptable Solution (A) Comments about compliance

A1

The location of buildings and works must comply with any of the following:

(a) be located within a building area, if provided on the title;

Complies with A1.

No buildings are proposed so clauses (a) and (b) are not relevant.


39

(b) be an addition or alteration to an existing building;

(c) be located in and area not require the clearing of native vegetation and not on a skyline or ridgeline.

The activity does not require the clearing of native vegetation and nor is it located on a skyline or ridgeline.

A2

Exterior building surfaces must be coloured using colours with a light reflectance value not greater than 40 percent.

Complies with A1.


P3

The depth of any fill or excavation must be kept to a minimum so that the development satisfies all of the following:

(a) does not have significant impact on the rural landscape of the area;

(b) does not unreasonably impact upon the privacy of adjoining properties;

(c) does not affect land stability on the lot or adjoining areas.

Complies with P3.

The development and use do not and will not have a significant impact on the rural landscape. The activity is located on land that is at the end of a public road which is a no through road ‐ it is not a tourist route.

The existing activity does not unreasonably impact on the privacy of adjoining properties. The proposed development and use will equally not unreasonably impact on the privacy of adjoining properties.

The nearest residential dwelling in other ownership is approximately 620 m away from any proposed sand extraction area on the other side of a ridgeline.

The activity is for sand extraction which requires excavation. The development and use will not affect land stability on the lot or adjoining areas. Further, land stability is improved with the removal of erodible sand deposits.

C.6 SCHEME CODES AND OVERLAYS

C.6.1 Bushfire prone areas

The Code does not apply to this use and development.

C.6.2 Potentially contaminated land

The Code does not apply to this use and development.

C.6.3 Landslide

This Code applies to:

(a) Development for buildings and works or subdivision on land within a Landslide Hazard Area;

(b) Use of land for vulnerable use or hazardous use within a Landslide Hazard Area.

Several small areas within the Mining Lease intersect the Low Hazard Band identified on the Landslide Hazard Area Overlay (Figure C‐3c). Areas of sand extraction do not and will not intersect the overlay. The Code is therefore not relevant to the use and development.


40

C.6.4 Road and Railway Asset Code

The purpose of this provision is to:

(a) protect the safety and efficiency of the road and railway networks; and

(b) reduce conflicts between sensitive uses and major roads and the rail network.

Under clause E5.2.1, this Code applies to use or development of land:

(a) that will require a new vehicle crossing, junction or level crossing; or

(b) that intensifies the use of an existing access; or

(c) that involves a sensitive use, a building, works or subdivision within 50m metres of a Utilities zone that is part of:

(i) a rail network;

(ii) a category 1 ‐ Trunk Road or a category 2 ‐ Regional Freight Road, that is subject to a speed limit of more than 60km/h kilometres per hour.

The development and use does not require a new access.

The following relevant Use Standards have been considered in this application.

E5.5.1 Existing road access and junctions


A1 The annual average daily traffic (AADT) of vehicle movements, to and from a site, onto a category 1 or category 2 road, in an area subject to a speed limit of more than 60km/hr, must not increase by more than 10% or 10 vehicle movements per day, whichever is the greater.

Not relevant to the development – site does not access a Category 1 or 2 road.

A2 The annual average daily traffic (AADT) of vehicle movements, to and from a site, using an existing access or junction, in an area subject to a speed limit of more than 60km/h, must not increase by more than 10% or 10 vehicle movements per day, whichever is the greater.

Not relevant to the development – posted speed limit is 60 km/hr.

A3 The annual average daily traffic (AADT) of vehicle movements, to and from a site, using an existing access or junction, in an area subject to a speed limit of 60km/h or less, must not increase by more than 20% or 40 vehicle movements per day, whichever is the greater.

Complies.

The posted speed limit is 60 km/hr.

The increase in vehicles accessing The Land will be less than 40 vehicle movements per day.

E5.5.2 Existing Level Crossings

Use Standard is not relevant to this activity – there is no access over a level crossing.

The following relevant Development Standards have been considered in this application.


41

E5.6.1 Development adjacent to roads and railways

Development Standard is not relevant to this activity – there is no access near a railway line, level crossing or a category 1 or 2 road.

E5.6.2 Road accesses and junctions

No new accesses or alteration to current access arrangements are proposed so this aspect is not relevant to the development.

E5.6.4 Sight distances at accesses, junctions and level crossings

The development complies with the Acceptable Solution A1 – sight distance onto the access road are more than those stipulated in Table E.5.1 of the Scheme.

C.6.5 Parking and Access

Two car spaces (Clause E6.6.1) are required for every 3 employees that are associated with the development pursuant to Table E6.1 of the Scheme. Two car spaces are available on entry to the property in a safe area away from active works.

No motorcycle spaces (Clause E6.6.3) are required as the activity will not be accessed or utilised by staff on motorbikes – they will need to use light vehicles and trucks to access the site.

No bicycle spaces are required as per Clause E6.6.4 and Table E6.2.


The development and use comply with Clause E6.7.1 as there is only one access.

E6.7.2 Design of Vehicular Accesses


P1 Design of vehicle access points must be safe, efficient and convenient, having regard to all of the following: (a) avoidance of conflicts between users including vehicles, cyclists and pedestrians; (b) avoidance of unreasonable interference with the flow of traffic on adjoining roads; (c) suitability for the type and volume of traffic likely to be generated by the use or development; (d) ease of accessibility and recognition for users.


The existing access is solely used by the owners of Flexmore Park. Shark Point Road is a no through road that terminates at The Land the subject of this application.

The access in its current form is safe and efficient for the movement of trucks and other vehicles from The Land.

E6.7.3 Vehicular passing areas along an access


P1

Vehicular passing areas must be provided in sufficient number, dimension and siting so that the access is safe, efficient and convenient, having regard to all of the following:

(a) avoidance of conflicts between users including vehicles, cyclists and pedestrians;


Sight distance is not relevant as the property access directly becomes Shark Point Road, there is no intersection or junction. Figure B‐1 shows the access and egress from the property.

No passing bays along the access road are needed in this development.


42

(b) avoidance of unreasonable interference with the flow of traffic on adjoining roads;

(c) suitability for the type and volume of traffic likely to be generated by the use or development;

(d) ease of accessibility and recognition for users.

The property is not open to public access.

There is no conflict between users of the access from Shark Point Road as it immediately proceeds onto a private internal property road used by the owners and visitors to the property.

The entrance is clearly demarcated by a gate.

E6.7.4 On‐site turning


A1

On‐site turning must be provided to enable vehicles to exit a site in a forward direction, except where the access complies with any of the following:

(a) it serves no more than two dwelling units;

(b) it meets a road carrying less than 6000 vehicles per day.

Development complies with A1.

Vehicles, including trucks can turn within the storage and handling area and to exit in a forward direction.

E6.7.5 Layout of parking areas


P1

The layout of car parking spaces, access aisles, circulation roadways and ramps must be safe and must ensure ease of access, egress and manoeuvring on‐site.


Vehicles, including trucks can turn within the storage and handling area and to exit in a forward direction.

Car parking is available on entry to the property in a safe area away from active works.

E6.7.6 Surface treatment of parking areas


P1

Parking spaces and vehicle circulation roadways must not unreasonably detract from the amenity of users, adjoining occupiers or the quality of the environment through dust or mud generation or sediment transport, having regard to all of the following:

(a) the suitability of the surface treatment;

(b) the characteristics of the use or development;

(c) measures to mitigate mud or dust generation or sediment transport.


The access is from an unsealed road.

The parking spaces and vehicle circulation roadways are also gravel/sand and will remain so.

The roadways are formed using all‐weather materials to ensure all‐year access and have culverts and drains associated with them to direct water away from the road surface and into existing drains on the property.

Dust if generated by road use on The Land is unlikely to cause environmental nuisance to adjoining lots as they are a considerable distance from the storage and handling area and extraction areas for the activity, and there are no nearby sensitive uses to The Land.


43

Sediment transported from the storage and handling area is caught by the adjoining sediment pond and sediment will be collected in the culverts and spoon drains associated with the roadways. This material can be used for rehabilitation works or for use in the final product.

E6.7.7 Lighting of parking areas


A1

Parking and vehicle circulation roadways and pedestrian paths serving 5 or more car parking spaces, used outside daylight hours, must be provided with lighting in accordance with clause 3.1 “Basis of Design” and clause 3.6 “Car Parks” in AS/NZS 1158.3.1:2005 Lighting for roads and public spaces Part 3.1: Pedestrian area (Category P) lighting.


Only 2 car parks are provided so lighting provisions are not required.

E6.7.8 Landscaping of parking areas


A1

Landscaping of parking and circulation areas must be provided where more than 5 car parking spaces are proposed. This landscaping must be no less than 5 percent of the area of the car park, except in the Central Business Zone where no landscaping is required.


Only 2 car parks are to be provided so landscaping provisions are not required.

The remainder of the Development Standards in this Code are not relevant to the development and use.

C.6.6 Stormwater Management

The purpose of this provision is to ensure that stormwater disposal is managed in a way that furthers the objectives of the State Stormwater Strategy. This code applies to development that requires the management of stormwater. This Code does not apply to use.

The catchments associated with the development and use are shown in Figure D‐6.


E7.7.1 Stormwater disposal and management

Performance Criterion (P) OR

Acceptable Solution (A)

Comments

A1 Stormwater from new impervious surfaces must be disposed of by gravity to public stormwater infrastructure.

Not relevant to the development

No new impervious surfaces are proposed for the activity.


44

A2 A stormwater system for a new development must incorporate water sensitive urban design principles R1 for the treatment and disposal of stormwater if any of the following apply: (a) the size of new impervious area is more than 600 m2; (b) new car parking is provided for more than 6 cars; (c) a subdivision is for more than 5 lots.


No new impervious surface is proposed for the development and use – the storage and handling area was in existence under the current permit.

No new external haul routes to transport merchantable products from the storage and handling area are proposed. That which exists is shown in Figure B‐2.

Internal haul routes from the storage and handling area to extraction areas are generally temporary (they are mainly incorporated back into agricultural land use at the end of sand extraction at any given area) or they are internal farm tracks used to operate the farm. These Internal haul routes do not represent an impervious surface as defined in the Scheme.

Car parking is provided for 2 spaces only.

The development is not a subdivision.

A3 A minor stormwater drainage system must be designed to comply with all of the following:

(a) be able to accommodate a storm with an ARI of 20 years in the case of non‐industrial zoned land and an ARI of 50 years in the case of industrial zoned land, when the land serviced by the system is fully developed;

(b) stormwater runoff will be no greater than pre‐existing runoff or any increase can be accommodated within existing or upgraded public stormwater infrastructure.


A minor stormwater drainage system is not required.

Given the activity is a Level 2 activity within the meaning of EMPCA, the Environment Protection Authority will assess stormwater management.

A4 A major stormwater drainage system must be designed to accommodate a storm with an ARI of 100 years.


A major stormwater drainage system is not required.

Given the activity is a Level 2 activity within the meaning of EMPCA, the Environment Protection Authority will assess stormwater management.

C.6.8 Attenuation

The purpose of this provision is to:

(a) minimise adverse effect on the health, safety and amenity of sensitive use from uses with potential to cause environmental harm; and

(b) minimise likelihood for sensitive use to conflict with, interfere with or constrain uses with potential to cause environmental harm.

This code applies to:

(a) development or use that includes the activities listed in Table E9.1 and E9.2 in a zone other than the Light Industrial, General Industrial or Port and Marine Zone;

(b) development or use for sensitive use, including subdivision intended for sensitive use;

(i) on land within an Attenuation Area shown on the planning scheme maps, or

(ii) on land within the relevant attenuation distance from an existing or approved (permit granted) activity listed in Tables E9.1 and E9.2 if no Attenuation Area is shown on the planning scheme maps and that activity is not located in the Light Industrial, General Industrial or Port and Marine Zone.

Pursuant to Clause E9.4.1 of the Code, the use and development is exempt because the activity requires assessment under the Environmental Management and Pollution Control Act 1994 by the Board of the Tasmanian Environment Protection Authority.

PART D ‐ POTENTIAL ENVIRONMENTAL EFFECTS

D.1 SURFACE WATER. GROUNDWATER AND DRAINAGE

The drainage from the stockpile and handling area is shown in Figure B‐3, with regional drainage and

catchments shown in Figure D‐6.

The stockpile and handling area is sloped towards the sediment pond as too are the drains that direct water

to it, as shown in Figure B‐3. The sediment pond is about 1Ml capacity and receives occasional water from a

natural drainage line that originates off the property. It is fitted with a drainage pipe which flows into an

existing channel from which the water can be pumped to irrigation areas.

Farm water management ensures runoff is retained and does not reach Pittwater. There are three major

water storages on the farm with a combined capacity of 400 ML, used for irrigation and stock water.

Occasional runoff from the higher dolerite hills to the east of the mining lease is harvested and diverted by a

1.5Km of contour channel (existing) into storage for future use as outlined above.

Water drainage from localised areas of sand extraction has not been shown because these areas are never

subject to external flows, due to the diversions as outlined above. The inherent natural drainage of the deep

sand profile easily copes with typical rainfall events the area receives. Minor sediment movement is readily

captured by pasture surrounding the extraction areas.

D.2 BIODIVERSITY

D.2.1 Vegetation

No native vegetation will be cleared or impacted upon by the sand extraction activity. No specific management measures are proposed as none are warranted.

D.2.2 Threatened Flora Species

No threatened flora species have been recorded in the Mining Lease (see Figure D‐8) based on the Natural Values Atlas (a DPIPWE maintained database of natural values) and surveys in 2017. No specific management measures are proposed as none are warranted.

D.2.3 Weeds

Declared weeds within the Mining Lease include Californian thistle and boxthorn (Figure D‐9). Weeds are managed in the sand extraction areas via a weed spraying program implemented as part of normal agricultural activities on the property.

D.2.4 Threatened Fauna Species

No mammal dens or other threatened fauna species were recorded within the activity area during site surveys. There are no wedge‐tailed eagle or white‐bellied sea eagle nests within 1km of The Land. No specific management measures are proposed as none are warranted.

D.3 AIR EMISSIONS

The tracks into the activity area have a gravel surface. Potential sources of dust from the operation are ‐

The removal of vegetative cover and stripping of topsoil;

The excavation of in situ sands and soils;

The movement of sand at the point of extraction by machinery;

Track (gravel) use within the Mining Lease;

Screening rocks and roots from the sand;

Stockpiling and loading of sands and topsoil.

In dry weather water from the sediment pond or on‐site water cart truck will be used to dampen the road surface, area near the stockpiles and loads in trucks (unless they are covered by tarpaulins).

D.4 LIQUID EFFLUENT

There will be no toilet or other amenities provided on site so there will not be any discharge of liquid waste from the activity. Therefore, water quality monitoring and effluent treatment measures are not proposed.

D.5 SOLID WASTES

The activity does not produce any solid wastes because all the materials extracted are sold for various end uses or used for rehabilitation of land (eg clay clods screened from the sand is reused in pasture rehabilitation in conjunction with biosolids).

The servicing of machinery may generate solid waste (e.g. oil filters, worn tyres) however machinery will be serviced at the on‐property workshop. Waste generated by the servicing of machinery will be disposed of in accordance with best practice principles.

Waste generated by workers from general refuse (eg lunch wrappers) at the activity is removed each day. No waste bins will be provided on‐site for general refuse.

D.6 TRANSPORT IMPACTS

Material will be regularly extracted in small volumes per week, with activities and haulage occurring on most weekdays (within the 0700 to 1900 hrs as per Table 1) to meet demand for the product.

Unlike a hard rock quarry where there are normally ‘campaigns’ for road works or other major project (eg dam spillway, bridge reconstruction) the sand product from Flexmore Park is used in several construction and landscape/horticultural applications so there needs to be small but regular supply.

A truck would normally cart 20 to 30 tonnes of sand. A cubic metre of damp sand product on average would be around 1,600 kgs. Hence, the annual production of 20,000 cubic metres is about 32,000 tonnes (subject to the quantum of moisture within the sand and the particle size). Assuming a 30‐tonne truck to haul material from the activity, the annual extraction could be achieved in about 1,000 truckloads spread throughout the year. On a basis of 240 operating days per annum (assuming Monday to Friday carting only, although the application is to seek carting approval for Saturday also, see Table 1), this is about 5 trucks per day (10 truck movements). Even using a 20‐tonne truck, this is only 1,600 truckloads which means 7 trucks per day (14 truck movements) over the operating 240 days.

Light vehicle movements comprise a very small proportion of overall vehicle movements to the activity area ‐ a maximum of 2 per day (4 vehicle movements).

Given the very low generation of traffic volumes and the strict operating hours (within the Quarry Code of Practice operating hours), no activity‐specific management measures seem warranted, so none are proposed.

D.7 NOISE EMISSIONS

D.7.1 Existing Landscape Noise Sources

Noise sources in the landscape surrounding the land where the activity will occur have been identified as follows:

Aircraft frequently flying into and out of the Hobart International Airport;

vehicles and trucks using the Shark Point Road;

boats, ships and other pleasure craft on Pittwater;

agricultural‐related activities (livestock, ploughing, fertilising, harvesting, shooting etc);

occasional forestry‐related activities (harvesting, plantation management etc);

wave activity in the Ramsar Wetland during high wind events;

wind in the forest (native and plantation); and

bird and insect life.

D.7.2 Activity Noise Sources

The major noise sources from the activity have been identified as follows:

• excavating soils and sand;

• truck movements on the site;

• occasional screening in the storage and handling area; and

• on‐site use of ancillary equipment; excavators, loader and truck movements.

D.7.3 Sensitive Receptors

The nearest sensitive receptors are identified in Figure D‐3 and include ‐

a house more than 635 m to a sand extraction area and 880 m to the storage and handling area and is located on the other side of a ridgeline; and

a house more than 620 m to a sand extraction area and 930 m to the storage and handling area.

Extraction of sand at each area only involves the use of a truck to cart material and an excavator, no blasting, drilling, crushing or screening is required to extract the sand.

D.7.4 Noise Assessment and Management Summary

The below aspects of the site and the activity can be summarised to indicate that noise emissions of the activity are very likely to be acceptable to the local conditions:

Machinery is well maintained to minimise the risk of generating excessive noise emissions;

Operating hours are those in Table 1; and

The nearest sensitive receptor is more than 620 m to a sand extraction area and 930 m to the storage and handling area and is located on the other side of a ridgeline (Figure D‐3).

D.8 HAZARDOUS SUBSTANCES AND CHEMICALS

Fuel and oil is used in the activity to operate and maintain functional machinery. Fuel for machinery and plant used in the sand extraction activity will only be stored onsite during the day and will be removed from


62

the site overnight – a transportable fuel tank of about 100 litres in the tray of a ute. The fuel will be used to re‐fill diesel tanks on plant and equipment.

One spill kit will be stored at the storage and handling area and workers trained in how to use it in the event of a spillage. It will be replenished as necessary.

Major repairs to plant and equipment will be completed off‐site in an appropriately equipped workshop.

Minor repairs and servicing including emergency repairs will be completed by a mobile mechanic with facilities for draining oils and engine liquids into fully sealed bunded containers will be used. This work will be completed near the storage and all waste (low volumes) will be taken off‐site and disposed of in accordance with Tasmanian waste disposal requirements. Some mechanical work may be completed at the on‐property workshop which is well equipped given the workshop also supports a large agricultural enterprise which utilises farm equipment and vehicles.

Weed spraying chemicals (the activity does co‐occur with an agricultural use) are handled, used and disposed of in accordance with the manufacturer’s directions and relevant Government regulations.

D.9 CLIMATE CHANGE

Energy Use

Energy use from the activity includes fuel consumption for operating machinery and transporting materials. The fuel type for the machinery and transport trucks is diesel.

Energy Use Conservation

Trucks used to transport the product are typically loaded to full capacity for transport therefore reducing the number of movements to and from the site.

Alternatives

There are no other alternative methods to transport of the materials. The trucks are not available as electric vehicles. There are no alternative methods of extraction.

Climate Change Impacts

Potential impacts of climate change, such as intense storm events are not expected to impact the proposal. Similarly, periods of low rainfall and dry periods are not expected to adversely impact the quarry operations.

D.10 EUROPEAN HERITAGE

There are no areas or buildings within the Mining Lease that are listed on the Tasmanian Heritage Register or Tasmanian Historic Places Inventory (maintained by Heritage Tasmania).

D.11 ABORIGINAL HERITAGE

The EPA sought advice from Aboriginal Heritage Tasmania (AHT), which provided information about the site.

There is one Aboriginal heritage site recorded within the property, consisting of a shell midden with an associated artefact scatter; however, due to the age of the recording (1981) details regarding the size and extent of the site were not provided to AHT.

The Unanticipated Discovery Plan will be applied (see Attachment 2).

D.12 MARINE AREAS

The Mining Lease is located adjacent to the Pittwater Nature Reserve (D‐1) which is part of the Pittwater – Orielton Lagoon Ramsar Wetland. The Tasmanian Parks and Wildlife Service identify in their notesheet for the site (https://www.parks.tas.gov.au/file.aspx?id=11639) the following threats –


63

‘The water quality of this wetland and the animals and plants that depend upon it are at risk from contamination entering via storm‐water drains and from removal of native coastal vegetation.

Disturbance of birds by people and dogs reduces the ability of migratory birds to feed and restore energy and causes the resident birds to leave their eggs unattended and vulnerable to predation or extremes in temperature.

Eggs and chicks of resident shorebirds are also at risk from predation by dogs and cats, and from trampling by people or crushing by horse’s hooves, bikes and vehicles.’

The sand extraction activity is unlikely to impact the marine environment because water management measures already exist and will continue to be maintained to prevent sediment entering the marine environment. There is minimal usage of fuels for the activity and no large volumes for the sand extraction activity are stored on the property.

Bird disturbance by dogs and people will not occur because of the sand extraction activity.

It is unlikely that noise from the activity will affect marine and migratory birds, the extraction areas occur within the flight path of the Hobart International Airport which provides both a noise source for the local environment and an impact hazard to migratory birds that may occur in the area.

D.13 MONITORING

Informal monitoring of the current activity is completed by the Sand Extraction Operator in consultation with the landowner (proponent) regarding weeds, general housekeeping, waste, stabilisation of extraction areas and safety checks. This process will continue for the intensified activity.

The Sand Extraction Operator is responsible for the day to day operation of the activity including compliance with relevant Tasmanian legislation, including but not limited to the following;

• Environmental Management and Pollution Control Act 1994

• Workplace Health and Safety Act and Regulations

• Aboriginal Relics Act 1975

• Threatened Species Protection Act 1995

General housekeeping and safety are the responsibility of the Sand Extraction Operator.

D.14 SITES OF HIGH PUBLIC INTEREST

There are no sites of high public interest adjacent to or near the sand extraction activity.

D.15 SITE CONTAMINATION (HISTORICAL)

The site has been used for agricultural (grazing) and sand extraction activities. No potentially contaminating activities are known to have occurred on the site. No contaminated soil has been imported or used on the site for landfilling. No activity is known to have occurred on the site to cause groundwater contamination.

D.16 REHABILITATION

D.16.1 Background

Flexmore Park, as noted in section A.6, is a coastal agricultural enterprise where the soils are predominantly comprised of sands or sandy loams. Significant farm improvements have been made concurrent to the extraction of sands for sale into the construction and landscape/horticultural sectors.

Agricultural improvements include the below –

Establishment of farm water storage basins and channels for drainage and water harvesting


64

• Few potential water storage sites exist on the property where low cost conventional dam wall construction can provide affordable capacity. The ability to remove merchantable materials from water storage sites both help fund earth moving costs and greatly increases capacity on marginal sites.

Improvements to topographic landforms for irrigation and cropping

• Land levelling of sand hills to provide improved topography for more efficient farming operations and enhance land capability.

• Enabling broad scale irrigation area development. Difficult topography of steep sand ridges fragment irrigation areas if they are not removed.

• To spread and level sand hills and ridges, rather than remove, contaminate otherwise more productive surrounding land, creating an increased erodible area.

Under progressive management the development of the farm should continue at a manageable and sustainable pace. The property location favours the integration of farm development with sand extraction due to proximity to a market for sand (ie lower transport costs) but benefits from its relative isolation by a long boundary with Pittwater, Pontos Hills to the east and the absence of public road frontages and residential developments.

D.16.2 Rehabilitation Approach

Progressive rehabilitation ensures a minimum area of land ‘open’ to lessen the impact the activity has on the surrounding farmland and the wider environment. The Mining Lease permits an ‘open’ area of no more than 6 hectares.

Experience over the past 20 years of sand extraction has resulted in the following procedures being applied to return the land to an enhanced productive use;

• Land levelling to the desired topography.

• Spreading of farm sourced clay (sand screening residue and clay from water storage enlargements) applied at up to 100 tonnes per hectare, incorporated into top 10cm, producing a physically stable layer resistant to wind erosion and enables nutrient and water retention which the original sandy soils lack.

• Spreading of biosolids to enhance fertility.

• Initially growing annual fodder crops followed by establishing perennial pastures and lucerne in subsequent years with applications of conventional fertiliser to continue the fertility build up.

Sand extraction sites which create water storages for irrigation and stock water are rehabilitated as follows;

• Internal and external batters including constructed clay walls are shaped to produce a slope no steeper than 3:1.

• Retained topsoil from the site is spread on all disturbed areas above the full supply level and lightly cross ripped.

• Aquatic grasses and sedges are established to control wave erosion of internal batters where water levels have seasonal variation.

• External batters are sown with Phalaris aquatica to provide a durable persistent grass cover.

D.16.3 PERMANENT CLOSURE

If the farm development focus changes to the extent that sand extraction and sale is no longer an integral component of farm land improvements, all disturbed operational areas of development projects at that time


65

will be brought to their planned completion as outlined in section D.16.2 and in joint agreement between the landowner, MRT and EPA.

It should be noted however, that sand extraction currently occurs to the extent required to fulfil the objectives of the various farm improvement projects. There often remains extensive deposits of sand beneath the improved landforms created.

D.17 ACID SULFATE SOILS (ASS)

Acid sulfate soils (ASS) and potential acid sulfate soils (PASS) have never been encountered nor intersected by the sand extraction activity. This is expected to be the case with future extraction because the extraction process does not remove all the aeolian sands in the one location. This limits the potential to excavate into a buried ASS or PASS layer. Notwithstanding this, as a precaution the document Acid Sulfate Soils – Indicators for Field Operators prepared and published by DPIPWE will be consulted and advice/recommendations taken on a needs basis. Management measures may include those described in the Tasmanian Acid Sulfate Soil Management Guidelines published by DPIPWE.

Unanticipated Discovery Plan

Procedure for the management of unanticipated discoveries of Aboriginal relics in Tasmania

Depar tment of Pr imar y Industr ies, Par ks, Water and Environment

For the management of unanticipated discoveries of Aboriginal relics in accordance with the Aboriginal Heritage Act 1975 and the Coroners Act 1995. The Unanticipated Discovery Plan is in two sections.

Discovery of Aboriginal Relics other than Skeletal Material

Step 1: Any person who believes they have uncovered Aboriginal relics should notify all employees or contractors working in the immediate area that all earth disturbance works must cease immediately.

Step 2: A temporary ‘no-go’ or buffer zone of at least 10m x 10m should be implemented to protect the suspected Aboriginal relics, where practicable. No unauthorised entry or works will be allowed within this ‘no-go’ zone until the suspected Aboriginal relics have been assessed by a consulting archaeologist, Aboriginal Heritage Officer or Aboriginal Heritage Tasmania staff member.

Step 3: Contact Aboriginal Heritage Tasmania on 1300 487 045 as soon as possible and inform them of the discovery. Documentation of the find should be emailed to [email protected] as soon as possible. Aboriginal Heritage Tasmania will then provide further advice in accordance with the Aboriginal Heritage Act 1975.

Discovery of Skeletal Material

Step 1: Call the Police immediately. Under no circumstances should the suspected skeletal material be touched or disturbed. The area should be managed as a crime scene. It is a criminal offence to interfere with a crime scene.

Step 2: Any person who believes they have uncovered skeletal material should notify all employees or contractors working in the immediate area that all earth disturbance works cease immediately.

Step 3: A temporary ‘no-go’ or buffer zone of at least 50m x 50m should be implemented to protect the suspected skeletal material, where practicable. No unauthorised entry or works will be allowed within this ‘no-go’ zone until the suspected skeletal remains have been assessed by the Police and/or Coroner.

Step 4: If it is suspected that the skeletal material is Aboriginal, Aboriginal Heritage Tasmania should be notified.

Step 5: Should the skeletal material be determined to be Aboriginal, the Coroner will contact the Aboriginal organisation approved by the Attorney-General, as per the Coroners Act 1995.

Unanticipated Discovery PlanProcedure for the management of unanticipated discoveries of Aboriginal relics in Tasmania

Abor iginal Her itage TasmaniaDepar tment of Pr imar y Industr ies, Par ks, Water and Environment

Stone Artefact Scatters A stone artefact is any stone or rock fractured or modified by Aboriginal people to produce cutting, scraping or grinding implements. Stone artefacts are indicative of past Aboriginal living spaces, trade and movement throughout Tasmania. Aboriginal people used hornfels, chalcedony, spongelite, quartzite, chert and silcrete depending on stone quality and availability. Stone artefacts are typically recorded as being ‘isolated’ (single stone artefact) or as an ‘artefact scatter’ (multiple stone artefacts).

Shell Middens Middens are distinct concentrations of discarded shell that have accumulated as a result of past Aboriginal camping and food processing activities. These sites are usually found near waterways and coastal areas, and range in size from large mounds to small scatters. Tasmanian Aboriginal middens commonly contain fragments of mature edible shellfish such as abalone, oyster, mussel, warrener and limpet, however they can also contain stone tools, animal bone and charcoal.

Rockshelters An occupied rockshelter is a cave or overhang that contains evidence of past Aboriginal use and occupation, such as stone tools, middens and hearths, and in some cases, rock markings. Rockshelters are usually found in geological formations that are naturally prone to weathering, such as limestone, dolerite and sandstone

Quarries An Aboriginal quarry is a place where stone or ochre has been extracted from a natural source by Aboriginal people. Quarries can be recognised by evidence of human manipulation such as battering of an outcrop, stone fracturing debris or ochre pits left behind from processing the raw material. Stone and ochre quarries can vary in terms of size, quality and the frequency of use.

Rock Marking Rock marking is the term used in Tasmania to define markings on rocks which are the result of Aboriginal practices. Rock markings come in two forms; engraving and painting. Engravings are made by removing the surface of a rock through pecking, abrading or grinding, whilst paintings are made by adding pigment or ochre to the surface of a rock.

Burials Aboriginal burial sites are highly sensitive and may be found in a variety of places, including sand dunes, shell middens and rock shelters. Despite few records of pre-contact practices, cremation appears to have been more common than burial. Family members carried bones or ashes of recently deceased relatives. The Aboriginal community has fought long campaigns for the return of the remains of ancestral Aboriginal people.
