Extractive Industry – Lot 4112 & 4375 – Worgan Road – Metricup – August 2015 – V2

- 1 -

1 IntroductionBCP Materials Pty Ltd (BCP) are, with the landowner’s permission, proposing to extract gravel from a deposit which has been identified within Lot 4112 and Lot 4375,Worgan Road, Metricup (the site). This report contains supporting information required by the City of Busselton (the City) as part of the development assessment and approval process for the proposed extractive industry.

The site is located approximately 23 km south-west of Busselton (Figure 1). The targeted deposit covers a total area of about 29.7 ha and is situated on cleared agricultural land currently used for livestock grazing. It is estimated that the gravel resource consists of about 222,750 m3 of material (assuming 0.75m average thickness but ranging between 0.5 and 3.0 m). The proposed pit area is shown in Figures 2, 3 and 4.

The extraction, crushing and screening of the gravel will take place on site with the product then being transported to various sites for use mainly within the City of Busselton and adjoining Shires. The life of the project is currently estimated to be about 5 years with gravel extraction commencing soon after the required approvals are obtained. The exact life of the project is however difficult to estimate as it is totally dependent on demand trends.

This document has been submitted to fulfil relevant requirements set out in The City’sDistrict Town Planning Scheme – Section 5A - Extractive Industry Provisions (adopted March 2010) and is intended to provide the City, the public and relevant government agencies with an understanding of the proposal and the environmental strategies and commitments applied to address various environmental and social issues.

In addition to general references, relevant recommendations and guidelines set out in the following publications have also been utilised during the preparation of thisdevelopment plan:

Environmental Management of Quarries (1991) – DME (now DMP);

Environmental Code of Practice - Extractive Industries (1990) – DEP (now EPA);

Water Quality Protection Guidelines No.6 (2000) – WRC (now DoW);

2 Location and Site Details2.1 Property Details and Ownership

The proposed gravel pit is located within Lots 4112 and 4375 (Plan 209906 - CT Volume 234 Folio 187A and CT Volume 112 Folio 133A – see Appendix A)which is owned by Rosemary Alice Worgan and David Victor Worgan. The site is bounded by Worgan Road to the south, Reserve 27906 to the north and other freehold properties to the east and west (see Figures 1 & 2).

With the owner’s permission the extractive industry licence and the associated development application (see Appendix B) are being applied for by BCP Materials Pty Ltd (BCP). Operations manager will be Kyle Jackson (P: 9752 1000).

2.2 Existing and Surrounding Land Use

The project is located in the City of Busselton, in an area zoned ‘Rural’. Under the City’s Extractive Industry Provisions (Plan 1) the project falls within Policy Area 3 (Shire of Busselton 2010). The policy recognises that this area contains sand and gravel deposits suitable for extraction and The City will support applications where it can be determined that visual, environmental, social and other impacts are minimised.

The entire proposed extraction area is cleared of native vegetation and iscurrently used mainly for livestock grazing. Most surrounding freehold properties are of a similar nature and are used for livestock grazing, agriculture/viticulture and some plantation timber. Several gravel and sand extraction industries similar to that being proposed are also in progress or have previously been undertaken in the vicinity (Figure 3).

Based on examination of the most recently available air photo (February 2015)there are 20 houses within a 1.5 kilometre (km) radius of the proposed extraction area’s boundary. Nine of these houses are within 1 km, and of these, three are within 500 metres (Figure 3).

Overall no significant amenity issues are anticipated. The extraction site is located in a rural area and at its closest point will be over 200 metres from the nearest road (Gale Road). In addition to distance, existing vegetation along the road, within the site and in adjoining areas provides a visual/dust/noise bufferand screen from road users and the limited number of closer residences.

2.3 Property Access

It is proposed to access the site from Gale Road through Reserve 27906(Figure 2). Access via Worgan Road is not viable as this road is not suitable for truck movements due to insufficient width/lack of bitumen seal. Gale Road has previously been upgraded for use by other extractive industry operations in the area and is the only viable access to the site for the purpose of gravel extraction.

Reserve 27906 was previously used as a gravel pit and has good access onto Gale Road via an existing wide entry. The reserve is largely cleared and it is anticipated that only a small number (3-4) of young, regrowth trees would need to be removed along the fence line between Lot 4112 and the reserve for construction of the access way to proceed.

An application to utilise Reserve 27906 as a temporary access way has been lodged with the Department of Lands with approval still pending.

2.4 Services

No new services will be required during the operation and rehabilitation of the pit area. There will be no disruption to existing services (power, gas or telephone) as a consequence of gravel extraction or transportation.

2.5 Description of the Site

The site lies on the Blackwood Plateau near the northern edge of the Donnybrook sunklands and south of the poorly defined Whicher Scarp. The area is comprised of low scarp slopes and terraces composed principally of laterite, colluvium and alluvium over sedimentary rocks. The area represents a degraded surface of planation and denudation that slopes down to the Whicher Scarp and then to the southern Swan Coastal Plain.

2.5.1 Landform and Soils

Soils and landforms of the area have been described and mapped by, Churchwood and McArthur (1980), Tille and Lantzke (1990), Agricultural Department (Agmap 2003) and most recently by The WA Geological Survey (2000).

With the abovementioned documents the area is mapped as forming part of the Treeton subsystem, which in general terms is composed of prominent low hills with very gently to moderately inclined slopes and broad swampy drainage depressions.

The landforms and soils present have formed from the insitu weathering of the underlying sedimentary rocks (Leederville Formation) with residual ferruginous duricrust and gravel being common on hillcrests (GSWA 2000). The target

DA15/0456



- 4 -

deposit is contained within a relatively thin layer of this ferruginous/gravelly sub-unit of the Treeton system and overlies mottled soils also formed by the weteig of the Leederville Formation.

2.5.2 Topography

The overall site is characterised by centrally located north south orientated ridge that has a maximum elevation of about 98m AHD. Topography slopes down to the east and west of the central ridge to about 60m AHD in the east and 65m AHD in the west.

The proposed extraction area, at the time of writing, has not been surveyed to determine exact contours.

2.5.3 Vegetation

The entire proposed extraction area is cleared of native vegetation and now consists of a thin layer of topsoil with a sparse array of introduced pasture grasses. Prior to clearing native vegetation would have been comprised of Jarrah-Marri forest and woodland.

2.5.4 Fauna

The proposed extraction area has almost no value for terrestrial fauna speciesexcept those that use highly degraded environments. The temporary use of the area for a gravel pit will have no detrimental effect on fauna persisting in the wider area. Extensive areas of a similar nature (paddocks with scattered groves of trees) are present in the general area.

2.5.5 Groundwater

Groundwater in the general region was investigated and reported on byAppleyard (1988). The most significant uppermost aquifers are contained withinthe Warnbro Group of sediments (of which the Leederville Formation forms part). The Warnbro Group is a multilayered aquifer system consisting of a number of local flow systems. Groundwater within the Warnbro Group is recharged by rainfall with infiltration occurring through the laterite and/or sand capping. Water levels in the aquifer vary seasonally by up to 2 m in response to recharge. Groundwater flow is controlled by topography with local flows discharging into creeks and swamps throughout the area (Appleyard 1988).

Potentiometric levels in the Warnbro Group vary greatly both laterally and vertically with the water table being controlled in part by topography and where discharge to surface water bodies occurs (Appleyard 1988).

Based on data within in Appleyard’s report (Appleyard 1988) it is estimated that the water table at the site is at least 10 to 15 metres below the surface given it is located on a topographic high. The maximum depth of the proposed

DA15/0456



- 5 -

extraction operation will be no more than 3.0m. The excavation of the pit will therefore not intersect or affect any groundwater aquifers present.

The site is not located in a priority Public Drinking Water Source Area(PDWSA).

2.5.6 Surface Water

The site is located within the catchment of the Carbanup River. Surface drainage of the area of the proposed extraction area is by sheet flow, following the slope in an easterly or westerly direction depending on the specific location. Based on the topography and soil type this external drainage falls into the moderately well drained category (McArthur 1991). The internal downward drainage (within the soil) would be classified as moderately permeable but is restricted by the mottled clay layer present under the upper gravelly horizons. The catchment area directly above the proposed pit area is of a very limited extent, the proposed pit site being positioned on or near the crest of a north south orientated ridge.

There are no watercourses, wetlands or dams within the bounds of the proposed extraction area. The nearest watercourses are represented by the Carbanup River in the east and a small tributary of the Carbanup River in the west. At their closest points, both these water courses are over 200m away from the proposed extraction area boundary.

2.5.7 Acid Sulphate Soils

In Western Australia the ASS risk maps were developed based on existing 1:50 000 urban and environmental geology map series published by the Geological Survey of WA (Degens 2006). The ASS risks are classified into two categories on the basis of ASS occurrence within the soil profiles:

high to moderate risk of ASS occurrence within 3m from the surface elevation;

moderate to low risk of shallow ASS occurrence at depth beyond 3m from surface elevation.

The proposed extraction areas within Lots 4112 and 4375 are mapped as having a “moderate to low risk of shallow ASS occurrence at depth beyond 3m from surface elevation” with no areas of “high to moderate risk” shown in the vicinity (Landgate 2015).

Given the proposed extraction will be confined to a maximum depth of less than 1m and the moderate to low risk factor at greater depths, the potential to activate acid sulphate soils is considered to be negligible. There are also no intervening clay rich layers and the target resource is positioned well above the water table (i.e. it is already exposed to air)..

3 Scale and Nature of Operations3.1 Extraction Process and Staging

The location and extent of the proposed gravel extraction area is shown in Figure 4. The resource covers an area of about 29.7 ha of cleared agricultural land and consists of approximately 222,750 m3 of gravel (assuming 0.75m average thickness but ranging between 0.5 and 3.0 m). If it is assumed that the annual amount of gravel extracted will be about 40,000 m3, the entire life of the project is estimated to be about five years with extraction commencing soon after the required approvals are obtained. The actual amount extracted will however depend on a variety of factors, primarily product demand.

The extraction, crushing and screening of the gravel will take place on site with the product then being transported to various sites for use mainly in road construction within the City and adjoining areas. Gravel extraction will be carried out using a bulldozer/front end loader. Portable crushing and screening equipment will be used to produce the final product. Most of the resource is anticipated not to require crushing. This process will be employed when and where required. There will be no blasting required. Excavators may also be used for some applications.

Extraction and rehabilitation will be staged so that at no one time is a combined area greater than 2 ha is exposed. The extraction sequence is designed to reduce the potential of wind and storm water erosion by limiting the open pit area as far practical. Indicative stage cells are shown within Figure 4 to illustrate their relative scale. The actual location of anyone cell may vary from this as a range of unknown variables affect actual pit layout at any one time.

Gravel will be extracted, crushed (if required), screened and transported typically in one operation removing the requirement for stockpiling for extended periods. If storage of processed gravel is required, stockpiles will be located within existing pit boundaries at a maximum height of 2.0 m and in a location that minimises potential amenity issues.

3.2 Vegetation and Topsoil Removal

The proposal will require the disturbance of about 29.7 hectares of cleared agricultural land. No natural vegetation will be cleared or impacted on.

Topsoil (including pasture grasses if present), a nominal 100mm thick will be removed prior to the commencement of operations on each cell. Topsoil on the site is relatively light in nature and will be stored in stockpiles no higher than 2.0m. Topsoil stockpiles for each 2 ha area will therefore have a maximum volume of about 2,000m3 (i.e. 2ha x 0.1m). Indicative topsoil stockpile locations

DA15/0456



- 7 -

are shown in Figure 4. The actual location of topsoil stockpiles may vary from this as a range of unknown variables affect actual pit layout.

3.3 Proposed Operating Times

Operating times will be restricted to between 7:00am and 6:00pm, Mondays to Fridays only, and exclude Public Holidays. Trucks will not to operate on Monday to Friday between hours specified by the City of Busselton on any given school day on a school bus route. Modifications to operating times (either temporary or permanent) may occur as a result of specific direction from the City.

Actual operating times within the prescribed periods will be dependent on product demand.

3.4 On-Site Maintenance of Vehicles

Fuel, oil, coolant and lubricant will be brought onsite as required by a fullycontained mobile service truck. The mobile service truck will be appropriately designed to prevent spillages to the environment and will carry appropriate spillprevention (e.g. drip trays) and clean-up equipment. All waste oil will be removed from site. No hydrocarbons of any type will be stored on site.

Where major servicing is required, the vehicle in question will be removed from site. In the event of a breakdown necessary precautions will be taken to ensure hydrocarbons do not enter the environment. Hydrocarbon spill kits will be utilised in the event of a spill and any contaminated soil will be contained and removed to an appropriate disposal site.

4 Resource Haulage4.1 Route Identification

Two routes, to and from the extraction area are proposed and will be used based on origin/destination. From the site an eastwards route is proposed along Gale Road and left onto Jindong-Treeton Road, right onto Paynes Road and then left onto either Kaloorup Road or Queen Elizabeth Avenue to gain access to Bussell Highway or the Busselton Bypass.

A westwards route along Gale Road will provide a short route direct to Bussell Highway.

4.2 Number of Truck Trips Generated by the Extractive Industry

Trucks used for the transportation of the material will vary between 6 wheelers (capacity ~10m3) and semi tippers (capacity ~18m3). Road trains (“B” trains -capacity ~25m3) will not be utilised.

It is estimated that on average about 19 truck movements a day will occur (assuming all semi tippers used) and ~40,000 m3 is moved per year (assuming ~241 working days). The transport of material will be dependent on demand and therefore periods of greater truck movements will occur while during other periods there will be no activity.

Based on previous experience the maximum number of truck movements expected would be around 50 per day during periods of maximum demand. Under these circumstances and the maximum possible daily operating time (11 hours), a truck movement would therefore occur about every 13 minutes.

4.3 Point of access onto the local road network

It is proposed to access the site via Gale Road through Reserve 27906 (Figure 2). As this access point has previously been approved/used by the City for this same purpose no additional upgrade works, apart from normal maintenance, are anticipated.

4.4 Rural Road Widths

All of the roads mentioned in Section 4.1 as the primary routes to main highways are already of the recommended standard for the increased traffic volume (truck movements) proposed. The current sealed width of all the roads is between 6.5 to 7.3 metres which complies with anticipated traffic volumes of no more than 500 vehicles per day (Table 3 - Shire of Busselton 2010). No additional upgrades of these roads to allow for the extractive industry to operateare therefore is anticipated.

4.5 Other Matters

If not already present approved road signs warning other road users of trucks entering and using the public road system will be installed along the proposed transport routes to the main highways (i.e. Gale Road, Jindong-Treeton Road, Payne Road and Kaloorup Road) and at other major intersections (e.g. Bussell Highway).

No additional upgrades (e.g. intersections, drainage or bridges) are anticipatedgiven the relatively small scale of the proposed activities and the fact that the proposed haulage routes are or have been in use for this same purpose for many years.

DA15/0456

5 Environmental Considerations5.1 Noise Management

Due to the rural location, limited operating times and screening provided by distance and existing vegetation, noise (and vibration) is not anticipated to cause any issues however a noise management plan will nonetheless be implemented to further reduce the chances of unforseen issues arising. The proposed Noise Management Plan is held in Appendix C.

5.2 Dust Management

A Dust Management Plan has been formulated and will be implemented during the life of the project to ensure that any dust created by activities onsite cannot possibly reach levels that could adversely affect the environmental values of health, welfare and amenity of people and land uses in the immediate vicinity. The proposed Dust Management Plan is held in Appendix D.

5.3 Dieback Management

The dieback status of the area to be excavated cannot be readily determined due to the lack of vegetation and/or indicator species however an examination of vegetation adjoining the proposed pit area strongly suggests the area is infected with one of the several species of Phytophthora fungus (i.e. dieback). This conclusion is based on the presence of dead jarrah and banksia trees, which are highly susceptible to the disease.

From a management perspective, extraction sites that have already been infected with dieback, or are classified as dieback uninterpretable, do not require quarantine of material or wash down of machinery entering or exiting the site. Such measures are generally used to protect dieback free material (a valuable resource) from becoming infected.

Nonetheless a Dieback Management Plan has been formulated and will be implemented during the life of the project with the principle aim of managing the extractive industry operation on the property to minimise the spread of Phytophthora spp. by mechanical means (unclean machinery). The proposed Dieback Management Plan is held in Appendix E.

5.4 Drainage Management

The proposed extraction operation will be designed, constructed and operated to avoid disruption of surface water flows, minimise erosion and ensure that potential contaminants are not released into the environment.

DA15/0456



- 11 -

A Drainage Management Plan (incorporating surface water/stormwater controls), will be implemented during the life of the project with the primary aim of ensuring no erosion or escape of silty water from the excavation site or from associated stockpiles occurs. The plan has been formulated to comply with relevant guidelines contained within the Water Resource Considerations for Extractive Industries document (DoW 2014).

Due to the limited catchment area upslope of the proposed pits, the unconsolidated nature of the soil and the proposed maximum 2 hectare size of the active excavation area it is anticipated that any surface water not diverted away from the site will be contained easily within the confines of the embankments of the pit excavations and will soak away through the soil profile on the lower pit face.

Because of this fact all stormwater captured within the confines of the pit operating at the time will be contained on-site and no sediments or turbid water will escape the site under any circumstances. Overland stormwater flows outside of the project excavation area will be diverted via bypass drains and/or earthen bunds around disturbed surfaces and/or stockpiled material.

Additional surface/storm water controls that will be put in place are described within the proposed Drainage Management Plan which is held in Appendix F.

5.5 Rehabilitation Management

Rehabilitation of the excavated areas will be progressive and will aim to return the land progressively back to its historical land use, livestock grazing, after the operations are complete. Given the depth of the proposed pit is relatively shallow minimal re-contouring will be required and the final land surface will have the same grade as the original surface minus the thickness of extracted material (0.5 to 3 metres). The proposed Rehabilitation Management Plan is held in Appendix G.

Noise Management Plan - Lot 4112 & 4375 – Worgan Road – Metricup – August 2015 – V2

1

1 IntroductionThe following noise management plan will be implemented during the life of the project to ensure that site works do not result in the generation/emission of unacceptably high levels of noise that may affect the existing local amenity to residents in the vicinity.

Based on examination of the most recently available air photo (February 2015) there are 20 houses within a 1.5 kilometre (km) radius of the proposed extraction area’s boundary. Nine of these houses are within 1 km, and of these, three are within 500 metres.

Machinery used to carry out gravel extraction, loading (a bulldozer and/or front end loader) and transport (trucks) will represent the main source of noise from the site during operation. The use of earthmoving equipment will be restricted to the gravel extraction area, whilst it is proposed that haulage vehicles will utilise the access track through Reserve 27906 to Gale Road, turning either left or right depending on destination.

Operating times will be restricted to between 7:00am and 6:00pm, Mondays to Fridays only, and exclude Public Holidays. Trucks will not to operate on Monday to Friday between hours specified by the City of Busselton on any given school day on a school bus route. Modifications to operating times (either temporary or permanent) may occur as a result of specific direction from the City. Actual operating times within the prescribed periods will be dependent on product demand.

Due to the small scale of the operation, rural location, limited operating times and screening provided by existing vegetation, noise is not anticipated to cause any issues however additional controls that will or may be put in place are described within the following management plan.

DA15/0456



2

2 Noise Management PlanManagement Actions:

Topsoil stockpiles will be put in place around the perimeter of the working pit and will act as noise bunds. Distance and existing vegetation will also contribute to minimising excessive noise transmission to nearby residences.

Restriction of noise generation activities to approved operating times (7.00am to 6.00pm Monday to Friday and exclude public holidays).

Internal traffic routing will be optimised to reduce vehicle reversing requirements (to minimise noise associated with reversing alarms).

Regular maintenance of plant and machinery: Identified noisy equipment will be removed or its use terminated pending repairs. Equipment identified as having excessive exhaust noise will be managed by fitting new/modified mufflers to minimise noise as far as practicable. Replacing standard ‘beepers’ with ‘quackers’ (a mixed frequency alarm which does not carry as far as the beeper) will be considered if currently fitted reversing beepers are identified as a noise issue.

If wind and/or cloud conditions increase noise travel in the direction of the nearest residences the option to cease relevant activities until weather conditions improve will be considered.

Education of employees and contractors will be incorporated into company and site inductions to raise awareness of noise management measures.

A noise complaint system will be put in place. This will included the erection of a notice at the site gate, providing contact details of the site manager. Any complaints relating to noise will be recorded by the site manager and acted on promptly. A register or complaints received and actions taken will be kept.

Regular operational checks will be carried out by site personnel as required to confirm operational targets (i.e. no noise complaints) are being met.

1 IntroductionThe following dust management plan will be implemented during the life of the project to ensure that any dust created by activities onsite cannot possibly reach levels that could adversely affect the environmental values of health, welfare and amenity of people and land uses in the immediate vicinity.

Potential Impacts: Specific aspects of the proposed operations that can contribute to dust include:

Earthworks during the normal operations (topsoil removal, resource stripping/excavation);

Crushing and screening;

Loading and haulage; and

Wind erosion of exposed surfaces during adverse weather conditions.

DA15/0456

2 Dust Management PlanManagement Actions:

Topsoil mounds will be no greater than 2 metres in height.

Stockpiles, where possible, will be limited to the anticipated cubic volume/vehicle movement for cartage on the following operating day.

Stockpiles will be located in appropriate areas to avoid prominent ridges or prevailing winds, and will include locating stockpiles within the pit area if necessary.

Stockpiles will be configured to accommodate easy access for watering/dust minimisation.

Water access road, immediate extraction area and fixed plant (screen) with water truck as required.

Use of dust suppression agents (for the purpose of reducing water use) as required.

Topsoil stockpiles will be watered and stabilised as required. Stabilisation techniques that will be considered depending on environmental conditions will included hydro-mulching and/or seeding with cover crops such as (but not limited to) cereal rye.

Minimise area impacted on and the time between extraction and rehabilitation (maximum 2 hectares open at any one time).

Education of employees and contractors to raise awareness of dust management measures.

Managing operations to minimise dust emissions during windy conditions. Timing of earthworks (daily and seasonally) will coincide with periods of low wind velocity. Operations will cease if winds are observed on site to exceed25 knots.

Truck loads will be covered by tarpaulins during transport.

A dust complaint system will be put in place. This will included the erection of a notice at the site gate, providing contact details of the site manager. Any complaints relating to dust will be recorded by the site manager and acted on promptly.

DA15/0456

Other factors that will assist in dust management include:

o Distance between occupied residences and the active pit area.

o Existing Vegetation: Vegetation along road reserves and on someadjoining properties provides a windbreak to reduce wind velocity andminimise dust mobilisation/transport in the first instance. The existingvegetation also acts as a filter to impede airborne dust leaving the sitein this direction.

o Water, when required, will be sourced from existing dams or bores onthe property.

Dieback Management Plan - Lot 4112 & 4375 – Worgan Road – Metricup – August 2015 – V2

1

1 IntroductionThe dieback status of the area to be excavated cannot be readily determined due to the lack of vegetation and/or indicator species however an examination of vegetation adjoining the proposed pit area strongly suggests the area is infected with one of the several species of Phytophthora fungus (i.e. dieback). This conclusion is based on the presence of dead jarrah and banksia trees, which are highly susceptible to the disease.

From a management perspective, extraction sites that have already been infected with dieback, or are classified as dieback uninterpretable, do not require quarantine of material or wash down of machinery entering or exiting the site. Such measures are generally used to protect dieback free material (a valuable resource) from becoming infected.

Nonetheless the following management plan will be implemented during the life of the project with the principle aim of managing the extractive industry operation on the property to minimise the spread of Phytophthora by mechanical means (unclean machinery).

DA15/0456



2

2 Dieback Management PlanManagement Actions:

Existing fenced paddocks and lockable gates will be maintained and used to control unauthorized access to the excavation area.

An unauthorized entry sign to be established at the property entrance.

As far as reasonable and practicable haulage vehicles are to be cleaned of all loose external soil and plant material prior to entry to and exit fromthe extraction area.

Extractive machinery and equipment (bulldozers/front end loaders, screen, etc.) to be cleaned of all soil and plant material prior to entry and exit to the extraction area.

Extraction site to be protected by an appropriate fence or barrier system of extraction to establish a separation zone between machinery working in the pit and haulage vehicles.

No direct water run-off shall be allowed into the naturally vegetated areasfrom the extraction area or access tracks.

No other main access tracks shall be used other than that shown on the map submitted with the original application unless approval from the City of Busselton is first obtained.

The extraction area will be managed to avoid ponding of surface water where vehicle access is required.

Trucks will be loaded and covered to ensure there is no spillage of material during transport.

Prospective buyers of the gravel to be notified of the dieback status of the material i.e. dieback infected.

Drainage Management Plan - Extractive Industry – Lot 4112 & 4375 – Worgan Road – Metricup – August 2015 – V2

1

1 IntroductionThe proposed extraction operation will be designed, constructed and operated to avoid disruption of surface water flows, minimise erosion and ensure that potential contaminants are not released into the environment. To this end thefollowing drainage (surface water/stormwater) management plan will be implemented during the life of the project with the primary aim being to ensure no erosion or escape of silty water from the excavation site or from associated stockpiles occurs.

The plan has been formulated to comply with relevant guidelines contained within the Water Resource Considerations for Extractive Industries document (DoW 2014).

Runoff up to the 10 year 2 hour average return interval storm event from disturbed areas will be managed to prevent mobilisation of sediments and all stormwater runoff from exposed areas will initially be contained on site. Runoff from undisturbed areas (i.e. with original topsoil and vegetation intact) will be diverted away from disturbed areas.

Due to the limited catchment area upslope of the proposed pits, the unconsolidated nature of the soil and the proposed maximum 2 hectare size of the active excavation area it is anticipated that any surface water not diverted away from the site will be contained easily within the confines of the embankments of the pit excavations and will soak away through the soil profile on the lower pit face.

Because of this fact all stormwater captured within the confines of the pit operating at the time will be contained on-site and no sediments or turbid water will escape the site under any circumstances. Overland stormwater flows outside of the project excavation area will be diverted away for excavate areas via bypass drains and/or earthen bunds around disturbed surfaces and/orstockpiled material.

Additional drainage/surface/storm water controls that will be put in place are described within the management plan.

The site is not located in a Priority Public Drinking Water Source Area (PDWSA) and published information clearly indicates that the maximum seasonal groundwater level in this area would be located well below the proposed pit floor.

DA15/0456



2

2 Drainage Management PlanManagement Actions:

It is anticipated that all surface water that collects within the excavation area will be contained easily within the confines of the embankments of the pit excavation and will soak rapidly away through the soil profile on the lower pit face.

If required cut off bunds and/or bypass drains will be put in place upslope of the active and previously mined areas. These will be positioned to divert surface water away from disturbed areas. As the proposed excavation areas are centred on or near the crests of topographic highsthe extensive use of cut off bunds is unlikely to be needed as the catchments area is very small and the ground unconsolidated and relatively permeable.

Within each cell gravel extraction will commence at the lowest point and this initial area will be deepened below normal extraction levels to form a detention basin area for surface water capture during the period of extraction and initial rehabilitation. The material extracted to create the detention basin will be stockpiled separately from topsoil and subsoil material.

Temporary detention ponds will be kept open until previous cells have achieved a good grass cover and cut off bunds (as required) have been created.

Based on previous experience in the area, it is considered unnecessarythat any detention or nutrient stripping ponds be installed outside of the pit areas as it is very unlikely that surface water will escape these areas.

The drainage management plan is designed to divert any water created during heavy rainfall events away from the pit area. Water that collects within the pit itself will be captured in a series of detention basins at the lowest points of the excavation area to allow sediment settling.

Due to the permeable nature of the soil at the site the retained water is expected to drain rapidly away and be filtered through the soil profile. As a consequence no overflow is expected and no silty water will escape from excavation areas.

As part of the initial rehabilitation of each cell, a series of 50 cm high “on contour” bunds will be constructed on the pit floor as extraction in each area is complete. If required the rehabilitation plan will also include “on

2 Rehabilitation Management PlanManagement Actions:

Extraction and rehabilitation will be staged so that at no time is a combined area greater than ~2 hectares is exposed at any one time.

All excavated areas will be graded to levels and contours conforming to the adjacent unaffected areas minus the thickness of excavated material (between 0.5 and 3.0 metres).

Deep ripping along the contour at 2 metre intervals (only required if low permeability soils encountered at base of pit).

Embankments/Cell batters will be cut to no more than 1 in 5.

Surface/storm water detention bunds along the contour will be created to a height of 0.5m.

Stockpiled topsoil from initial site preparation will be spread over the shaped surface.

Soil preparation - No specific soil preparation is anticipated. If warranted the rehabilitated pasture may be limed at 2.5T/ha. This will be determined by soil testing after extraction and initial rehabilitation is complete.

Seeding with appropriate agricultural seed mix: Revegetation of pasture grasses where required, will be carried out, preferably during autumn, using a mixture of oats, rye and clover at a rate of 60/25/5 kg/ha. Fertiliser will be applied at a rate of 240 kg/ha. Seed mixtures and fertiliser rates are indicative only and will be finalised after soil testing.

Temporary detention ponds will be kept open until previous cells have achieved a good grass cover and cut off bunds have been created.
