1.0 INTRODUCTION
1.1 BACKGROUND
Dana Minerals Pty Ltd (‘Dana’) is preparing to commence mining activities at their Meckering Kaolin Project (the ‘Project’).
This resource is potentially suitable for use as both filler clay for the paper industry, and as high quality ceramic clay.
Once mined, the kaolin will be bagged and sold “Free On Board” (FOB) at the mine gate to Dana (Shipping and Trading) Pty Ltd Singapore who manages all the overseas logistics and marketing of the product. 1.2 OBJECTIVE
The objective of this document is to support the Works Approval and Licence application for Gascoyne to construct and operate:
Category 12: Screening etc. of material: premises on which material extracted from the ground is screened, washed, crushed, ground, milled, sized or separated.
1.3 LOCATION
The Project is located approximately 140 km east of Perth and 8 km southeast of Meckering in the Wheatbelt region of Western Australia (Figure 1).
The Project is situated on privately owned, cleared agricultural farmland within the Shire of Cunderdin.
Figure 1: Location of Meckering Kaolin Project
1.4 OWNERSHIP AND LAND TENURE
The project lies on Mining Lease 70/1359 which is 100% owned by Dana Minerals Pty Ltd, a fully owned subsidiary of Dana Shipping and Trading.

2.1 CLIMATE
The climate of the region is semi-arid (Dry) Mediterranean which is associated with hot dry summers and cool winters. The summer periods can extend for five to eight months with the majority of rainfall, mostly in the 300-500 mm range, tending to fall in the winter months (Tille, 2006).
Cunderdin Airfield is the closest operating meteorological station with current data and is located approximately 18km to the northeast of the Project. Data collected from the Cunderdin Airfield station was used for this document.
The mean annual maximum temperature is 26.0oC whilst the mean annual minimum temperature is 10.5oC (BOM, 2017). Daily maxima above 32oC are usual from December to February whilst the coldest months are July-August (BOM, 2017) (Figure 3).
Figure 3: Mean maximum and minimum monthly temperatures for Cunderdin
2.1.1 Rainfall
The annual average rainfall is 302.7mm which falls (>1 mm) on an average of 48.5 days per year (Figure 4) (BOM, 2017). Most of the rain usually falls between May and September (BOM, 2017). The maximum rainfall ever recorded in one day at Cunderdin is 64 mm (BOM 2017). As shown in Figure 5, a 72 hr 100 year return period “storm” event results in 2 mm of rainfall.

2.1.2 Winds
The average wind speeds recorded at the Cunderdin Airfield vary throughout the year from 13.2-22.6 km/h in the morning and 18.5-22.1 km/h in the afternoon (Figures 6 and 7) (BOM, 2017).
The dominant wind directions experienced at the Cunderdin Airfield in the morning derive from the east whilst wind directions originating from the west and southwest (but with also an easterly trend) are common in the afternoon (BOM, 2017).

Figure 7: Annual 3pm wind rose for Cunderdin Airfield (BOM, 2017)
2.1.3 Humidity
Humidity data recorded at the Cunderdin Airfield vary considerably both daily and yearly. The mean monthly 9.00am relative humidity varies from a low of 42% in December to a high of 83% in July (BOM, 2017). The mean monthly 3.00pm relative humidity varies from a low of 23% in December to a high of 56% in July (BOM, 2017).

2.2.1 IBRA Region
The Project is located within the Avon Wheatbelt IBRA region and within the Re- juvenated Drainage (AW2) subregion (Beecham, 2001).
The Avon Wheatbelt is an area of active drainage dissecting a Tertiary plateau in the Yilgarn Craton. The AW2 comprises 3,012,977 ha, and is the erosional surface of gently undulating rises to low hills with abrupt breakaways. The AW2 region comprises continuous stream channels that flow in most years. Colluvial processes are active with soil formed in colluvium or in-situ weathered rock.
Clearing of native vegetation over the last 100 years for agricultural (farming) land has resulted in rising surficial groundwaters which have mobilised cyclic salt retained in the B horizon of the soil profile. These mobilised salts (secondary salinity) have been carried to rivers and streams resulting in the streams (since the mid 1920’s) changing from fresh water streams to brackish/saline streams.
2.2.2 Soil-landscape zone
The Project is situated within the Avon Province as described by the soil-landscape province mapping undertaken by Tille (2006). The Avon Province is dominated by an undulating plateau and occupies a total land area of approximately 169,325 km2 of which 93% is agricultural land (Tille, 2006).
The Project is located in an area where the terrain consists of rounded, moderately to gently inclined rises and low hills and is situated approximately 280 m above sea level. The terrain becomes further dissected to the west of the Project site where the valley floors become narrower and the drainage lines (although sometimes sluggish) flow in clearly incised courses during the winter period (Tille, 2006).
2.3 GEOLOGY
2.3.1 Regional Geology
The Project is located in the southern part of the granulite facies metamorphic belt of rocks termed the Western Gneiss Terrane. This belt extends north-northwest across the Perth sheet area for over 120km and varies in width from 15 to 65 km. Regionally, the strata dip to the east at moderate to steep angles, though there are large areas of sub- horizontally dipping strata near Toodyay and York.
The predominant rock type is a fine to medium-grained quartz-feldspar-biotite gneiss. It is usually well banded with distinct biotite-rich layers, but may be locally more massive. Both plagioclase (andesine/oligoclase) and microcline are present, though the relative proportions of these vary and porphyroblasts of garnet are locally abundant.
Deep weathering profiles are represented by developing or developed characteristics in the area which are related to the factors forming the profile. Weathering occurs in many different environments and on different parent rocks influenced by time, climate conditions, groundwater and/or drainage, geomorphology of the area and the composition of the parent rock.
2.3.2 Project Geology
The Project area has encountered significant weathering of granites and this lateritic weathering has leached into the lower B soil horizon. As a result, a combination of coarse grains (consisting mainly of quartz with minor microcline) and very fine kaolinite clay has been deposited.
Geological mapping and drilling has shown the regolith profile comprises a thin soil cover over a pisolitic limonitic laterite (ferricrete). The ferricrete, which is usually two to
9
ten metres thick, is usually underlain by a silcrete horizon up to two to three metres thick. A narrow band of weathered bedrock occurs above or below a layer of silcrete. The silcrete horizon is then underlain by the kaolin pallid zone, which typically passes into weathered bedrock or banded sandy clay. At the proposed mine site the base of the mottled zone is less than 10m from the surface and the kaolin pallid zone (clay zone and the saprolite) is extensively developed, exceeding 40 m in thickness in some places.
At the Meckering Project Site the base of the weathering profile is fresh rock (granitoid) overlain by zones of weathering products: pallid zone, mottled zone and ferricrete.
2.3.3 Geochemical Characterisation
Due to the extensive weathering and subsequent oxidation of the parent granitoid there is little chance of Acid Metalliferous Drainage (AMD) being an issue at the Project. Chemical analyses of the major elements of the in-situ and oversize material are reported in Table 2.
No sulphides or base metal oxides have been recorded in assays undertaken from samples collected during drilling activities at the Project area.
Table 2: Chemical Analysis of major elements
Element Bulk
2.3.4 Physical Characterisation - Overburden
A sample of deep overburden representative of the material to be removed during mining was analysed and recorded a pH of 8.7, with an EC and TDS of 62 µS/cm and 210 mg/kg respectively.
10
The sample contained low levels of both nitrogen and phosphorous with 16 mg/kg and 12 mg/kg being measured respectively. No ESP result could be determined from the sample as the material from this site was analysed to have a total Cation Exchange Capacity of <5 and is not sodic or dispersive.
2.4 SOILS
2.4.1 Description
Table 3 provides a summary of the soil units located in the Project area based on the Atlas of Australian Soils (Northcote et al., 1960-1968).
Table 3: Description of soil units in Project area and surrounds (Northcote et al., 1960-1968)
SOIL UNIT DESCRIPTION
Uf1 Uf1 Undulating terrain with ridges, spurs, and lateritic mesas and buttes: chief soils on the broad undulating ridges and spurs are hard, and also sandy, neutral, and also acidic, yellow mottled soils (Dy3.82 and Dy3.81), (Dy5.82 and Dy5.81), all containing ironstone gravels. Associated are a variety of soils on the shorter pediment slopes, including (Dr2.32), (Dr3.41), (Dy2.33), and others of similar form; and dissection products of the lateritic mesas and buttes. As mapped, small areas of unit Ms7 may occupy some drainage divides, unit Va63 traverse some drainage-ways, and unit Qb29 occur in localities of deeper dissection
MS7 Very gently undulating plains: dominant soils are sandy or, less commonly, loamy yellow earths (Gn2.22 and Gn2.25), with lesser loamy red earths (Gn2.12). Closely associated are slightly depressed areas with grey cracking (Ug5.25, Ug5.24, and Ug5.29) clays of unit CC38. Marginal to the small clay plains are loamy duplex soils (Dy2.43), (Dy3.43), and (Dy3.42)
2.4.2 Soil and Landform Survey
Soils in the surveyed area at the Project were found to be relatively uniform with little change throughout the landscape. In general, soils in the Project area comprise (Figure 8):
shallow sands over laterite with Sandy Clay Loams on the surface, increasing in texture down the profile to clayey horizons such as Fine Sandy Clay Loams - located over the majority of the Project area
deep yellow sand (Sandy Loam changing slowly to Sandy Clay Loam) was identified in the eastern and norther portion of the Project area – located on mid- eastern and southwestern section of the tenement (Figure 8).
exposed granite at surface.
There was no evidence of erosion at the Project site and the land condition was determined as stable. The stability of the land surface at the Project area can be attributed to the presence of agricultural cropping species and a gravelly (water repellent) soil surface.
No evidence of secondary salinity was observed across the Project area.
2.4.3 Chemical Analysis
Chemical analyses for the representative soils in the Project area are provided in Table 4.
The majority of soil horizons sampled were of a neutral to slightly acidic (pH values of 7.2 to 5.3).
EC measurements varied from <68-200 µS/cm.
11
Generally, the TDS levels were highest in the upper horizons (680 mg/kg) before decreasing through the soil profile (95 mg/kg).
Nitrogen and phosphorous were at the highest concentrations in the top horizon for each site before declining significantly through the soil profile. A higher concentration of nitrogen and phosphorus within the upper horizons of the soil profile is typical of areas impacted by intensive agricultural cropping, similar to that of the Project area, where nitrogen is provided from leguminous pasture species and phosphorous based fertilizers are applied to the land. Soil samples at the bottom and upper surface of the drainage line were analysed (Figure 11, Table 4). The soils were of a far higher salinity than the Project soils and this is expected given the evidence of pooling and resulting evapoconcentration of salts at the completion of surface flow. The base of the drainage line was clayey with sands at the upper surface.

2.5 SURFACE HYDROLOGY
The Project is located within the Avon River Catchment Area which is a Proclaimed Surface Water Area as set down in the Rights in Water and Irrigation Act 1914 (WA).
The nearest main drainage line within the vicinity of the Project is the Mortlock River East Branch which is located approximately four kilometres to the west of the Project.
The former land owner constructed diversion trenches which direct water to the existing dam located at the Project (Figure 4).
There are no permanent surface water bodies (i.e. rivers and lakes) in the Project area. Surface water runoff flows to the southwest of the tenement to an ephemeral drainage line (Plate 1).
This ephemeral drainage line only flows following heavy rainfall, as such; there is no surface water quality data available for the Project site or surrounds, or, surface water to sample.
2.6 GROUNDWATER
The hydrogeology of the Wheatbelt agricultural areas falls into two broad groups:
thin surficial sediments and narrow palaeochannels in broad flat valleys: and
weathered basement rock in the gently sloping hill slopes, also known as saprolite
aquifers (Dogramaci et al., 2009).
Groundwater in the general Project area is limited and the water table in the general area occurs more than 50m below the ground surface. There are no records of groundwater being encountered during exploration drilling undertaken within the Project area.
There are no operational bores or wells in the vicinity of the Project area. A bore is located 2km north of the Project area. This bore became dry following the 1968 Meckering earthquake.
The Project is not located within a Proclaimed Groundwater Area under the Rights in Water and Irrigation Act 1914. The Project will not impede on any local water sources. There are no public drinking water sources within the vicinity of the Project.
As there will be no groundwater abstraction required, and, as the pits will be mined above the groundwater table, no impacts to groundwater (and groundwater users) are anticipated.
Water will be sourced from the Water Corporation water pipeline which is located north of the Project.
2.7 VEGETATION AND FLORA
2.7.1 Vegetation
The Project area is situated in the Avon Botanical district within the South-West Botanical Province (Beard, 1981).
The Project is located on a privately owned farmland paddock of which the majority has been completely cleared of all native vegetation. There are isolated Eucalypt trees on the northern boundary and individual species are located in the creek line located on the western boundary of the tenement (Plates 1a, 1b, 2 and 3). These will not be disturbed by the proposed operations.
The Project area has been extensively cultivated for grazing and cropping purposes over many decades.
15
2.7.2 Flora
A search of the Federal Department of Environment (DoE) Environmental Protection and Biodiversity Conservation Act 1999 (EPBC) Protected Matters search tool and WA NatureMap reveal a number of records, with four species of conservation significance recorded within 5km of the Project:
Acacia volubilis (DRF).
Hakea aculeata (DRF).
Frankenia glomerata (P4).
Due to the long history of cropping within the Project area, only isolated patches of vegetation remain (Plates 2 and 3), none of which will be disturbed as part of the Project.
16
2.7.3 Weeds
The EPBC Protected Matters Tool lists six invasive species that have the potential to occur in the Project area:
Asparagus asparagoides (Bridal Creeper);
Cenchrus ciliaris (Buffel-grass);
Tamarix aphylla (Athel Pine).
Buffel grass is not common in the SW Agricultural Region and is a weed first appearing from the Gascoyne pastoral lands and then north through the Pilbara. Bitou Bush is a weed of coastal sand dunes and does not occur away from the coast.
Site assessments undertaken to date by Dana and CLA have recorded no invasive species. In addition, no Declared Pests (weeds), as listed by the Department of Agriculture and Food Western Australia (DAFWA) (2017) in accordance with Section 22 of the Biosecurity and Agriculture Management Act 2007, are located in the Project area.
2.7.4 Dieback & Pathogens
Dieback (Phytophthora sp) is a soil borne water mould that continually spreads by root to root growth amongst host plants and through the dispersal of zoospores in free-flowing water. Native animals, humans, vehicles and machinery can all transport Phytophthora sp (most commonly P.cinnamomi).
The effect of P. cinnamomi on the health of plant communities varies greatly. The root disease destroys the structure of many native communities, reduces their floristic diversity and primary productivity, and destroys the habitat of dependant native fauna.
The accepted range of Phytophthora sp across WA is restricted to the southern and western regions where average annual rainfall is greater than 600 mm; however, it can persist and have significant impact under favourable conditions within the 400 mm to 60 mm rainfall zone.
The Project area has an average rainfall of 302.7 mm, and is located on cropping land, thus, dieback is not considered an issue.
2.8 FAUNA
2.8.1 Terrestrial fauna
No fauna species of conservation significance were listed from the NatureMap search (DPaW 2017) in the Project area. A search of the Federal DoE EPBC Protected Matters search tool and WA NatureMap indicate 14 faunal species of conservation significance have been recorded in the region or have the potential to occur in the local area (i.e. within 20km) (Table 5).

2.8.2 Subterranean fauna
As no groundwater abstraction or mine dewatering is required for the Project, which would limit potential subterranean fauna habitat, there will be no impact on subterranean fauna (if they did occur).
2.9 THREATENED AND PRIORITY ECOLOGICAL COMMUNITIES
No Threatened Ecological Communities (TEC’s) or Priority Ecological Communities (PEC’s) are located in the Project area based on DPaW searches. The closest TEC and PEC are associated with the Mortlock River East Branch:
Priority 1 PEC – associated with the Salt Flat Plains of Mortlock River East Branch
Priority 1 TEC – ‘Salt Flats Plant Assemblages of the Mortlock River East Branch’

2.10 ABORIGINAL HERITAGE
A search of the Department of Aboriginal Affairs (DAA) Aboriginal Heritage Inquiry System (AHIS) shows no registered sites at the project area.
A risk assessment and register has been undertaken by Dana and CLA to identify potential risks associated with the existence of Aboriginal heritage and the minimisation of damage to Aboriginal sites (if discovered).
Dana has consulted the Department of Aboriginal Due Diligence Guidelines (DAA 2013) and the proposed mining activity is defined as a ‘Significant’ disturbance. However, given the proposed operations are contained within an area farmed for over a century, Dana considers there will be no impact to any Aboriginal Heritage site.
In accordance with Condition 5 on M70/1359, Dana will enter into a Heritage Agreement with the Ballardong People. Dana’s operations will be undertaken in accordance with this Agreement.
2.11 EUROPEAN HERITAGE
There are no items or heritage sites of European significance at the Project.
The Goldfields Water Supply Pipeline is a Listed Place on the Federal DoE Australian Heritage Database. It will not be impacted by the Project.
The Meckering Fault Scarp is listed as an Indicative Place on the Register of the National Estate (non-statutory list). It will not be impacted by the Project.

3.2 MINING
A 27 year mine plan has been developed, with mine designs completed out until year 27.
The 10 stage mine plan consists of 10 pits to be mined sequentially. Mining will occur on a campaign basis for 3-4 months per year. The Kaolin will be mined and stockpiled at the ROM pad. Initial raw material production will be approximately 340,000 t in the first year, then increasing to 1M tpa.
Mining will be via conventional truck/excavator open pit mining. Production drilling and blasting will not be required as all material is regarded as “soft and friable” and amenable to “free-dig”.
Incident rainfall collected in the pit will be pumped via in-pit sumps to the process water dam for use in dust suppression and at the wash bay.
3.3 WASTE DUMP
It is envisaged that processed oversized quartz/silica material from the on-site beneficiation plant and the mining waste material will be stored in-pit.
Removal of the oversized silica sand from the plant to the pit will occur on a continuous basis to avoid double-handling of the material. The oversize material will be separated and stockpiled for use as secondary product for the ceramic/tile industry and will be stored adjacent to the ROM. All remaining waste will be progressively disposed of in the open pits (as the pits become available).
A temporary waste dump will be located at the Project during Stage 1 mining. At the completion of Stage 2 mining, the material from the temporary waste dump will be backfilled into the pit.
There will be no final waste dump landform, as all material will be backfilled progressively into the previous mined stage.
3.4 KAOLIN BENEFICIATION PLANT
Dana will install a beneficiation plant at the Project (Figures 10 to 12) and a summary of the staged process is outlined in Table 8. The plant will consist of:
Conveyor Belt & Magnets to AST Dryer Feeder
Drying/Separation: AST Dryer
Twin Screw Cell Mills Feeder with integral (V) hopper
Cell Milling: 2 x Cell Mills with Classifiers & Bag Filters
Ball Milling : KGM Ball Mill system with Classifier.

3.5 ROM
The ROM pad will have a holding capacity of approximately 130,000 tonnes of stockpile material. It will be located to the north-west of the beneficiation plant (Figure 9).
3.6 DAMS
3.6.1 Process Water Dam
The location of the process water dam is shown in Figure 9. The dam will have dimensions of 50m x 50m and be lined with 1.5mm HDPE. The dam will have a capacity of 5,000 m3.
3.6.2 Environmental Dam
One environmental dam will be constructed south of the plant and associated infrastructure area to collect any surface water runoff from this area. The dam will be constructed of compacted soil and will have a capacity to hold runoff from the ROM and plant area and designed for a 100 year return period, 72 hour storm.
The existing farm dam will continue to collect surface water runoff from the northeast of the tenement until Stage 7 mining (when it will be encompassed by the developing pit.
3.7 RESOURCES
3.7.1 Water Supply
The two main sources of water for the project will be from the rainfall runoff water collected locally and stored in the site water dam, and water sourced (piped) from near the stand pipe on the scheme water pipeline located 2 km north of the minesite. Dana understands an allocation of 50 kL per day is achievable and this is expected to be in excess of the water requirements for the site.
The scheme water will discharge into the raw water storage tank.
The water tank will have sufficient capacity to allow fire-fighting capacity for the site in the event of fire. There will be no requirement for bore water on site.
3.7.2 Power
Dana will construct a dual diesel/gas-fired Power Station that will deliver a total of 8 MW power output.
A gas storage consisting of storage bullets will be situated beside the plant. The roads have been designed to allow gas trucks and diesel trucks to enter the site and unload without affecting the mining vehicles.
3.7.3 Dangerous Goods
The beneficiation plant does not require any reagents or chemicals in its operation.
3.7.4 Diesel and Hydrocarbons
All hydrocarbons and dangerous goods on-site will be stored and handled according to the Dangerous Goods Safety Act 2004 and the Dangerous Goods Safety (Storage and Handling of Non-explosives) Regulations 2007.
A centralised diesel fuel storage facility will be installed with a storage capacity of 100 kL. The facility will be bunded areas in accordance with AS 1940.
LPG will be delivered to site in pressurised delivery tankers with specialised off-loading pump facilities.
Waste oil and other hydrocarbons will be collected and stored in facilities that meet the requirements for the storage of dangerous goods. Waste hydrocarbons, including
28
hydrocarbon affected waste, will be stored in compliant receptacles, prior to removal for recycling from site by an approved contractor.
The proposed washdown bay at the plant and mining contractor’s area will include a contaminated water recovery system shared with the fuel facilities. The “cleaned” water will then be available for re-use. Collected contaminated waste will be pumped out by an approved contractor, removed from site and disposed of accordingly.
Spill kits will be made available for use to contain hydrocarbon spills. In the event of a spill, the contaminated soil will be collected and disposed of offsite to a licensed facility.
Fuel and chemical handling will be in accordance with the current Australian Standards for the storage and handling of flammable and combustible liquids under the Dangerous Goods Safety Act 2004 and associated Dangerous Goods Safety Regulations 2007.
3.8 INFRASTRUCTURE
Other surface facilities include:
Workshop –includes a washdown area located next to the workshop which will consist of a concrete washdown slab and waste oil management facility. The washdown slab will incorporate a silt trap and oil trap separator.
Offices
3.8.2 Haul and access roads
Access to the site is via Leeming Road.
Haul roads will be constructed for Stage 1-4 and Stage 5-10 of the operation.
Access to the site will be restricted (to prevent access by third parties) for safety purposes.
3.9 Waste Management
3.9.1 Sewage
A septic system will be installed for waste water from the site office/workshop and ablution facilities.
Approval to construct, install and operate this apparatus will be obtained from the
Department of Health and Cunderdin Shire in accordance with the Health (Treatment of Sewerage and Disposal of Effluent and Liquid Waste) Regulations 1974.
3.9.2 Refuse
All waste will be disposed of offsite at a licensed facility (most likely Meckering landfill site).
Scrap metal will be stored at a site near the plant and collected for recycling by a contractor.
Waste oils will be stored in isopods and removed from site for recycling to an appropriate recycling facility or disposal. Oil filters and hydrocarbon contaminated rags will be collected in approved receptacles and removed from site to an appropriate facility.
3.10 CONSTRUCTION
Construction is proposed to commence in Q3 2017 and is anticipated to take 3 months.
29
At the completion of construction of the beneficiation plant, a construction compliance certificate will be submitted to the DER outlining compliance with the design documents and conditions of the Works Approval.

6.1 DISTURBANCE
The Project will require disturbance of 78 ha of land over the mine life (27 years).
No clearing of native vegetation is required.
6.2 FLORA AND FAUNA
The Project does not require the clearing of native vegetation or native fauna habitat. Therefore, it is anticipated that there will be no impact to Threatened or Priority flora, and, native fauna of conservation significance resulting from the Project.
The Project area has been extensively cultivated for grazing and cropping purposes for a century. Isolated stands of trees and vegetation associated within a drainage line will not be disturbed by the Project.
There are no records of noxious weeds or Declared Pests at the Project.
The Project site will be searched periodically to ensure that there is no introduction or spread of significant weeds (i.e. Declared Pests).
6.3 SURFACE RUNOFF AND DRAINAGE
The Project is located within the Avon River Catchment Area which is a Proclaimed Surface Water Area as set down in the Rights in Water and Irrigation Act 1914.
The Project is not expected to have any major effect on surface water systems in the area. The Project site is located on hill crests and side slopes. There are no other rivers, lakes or other areas of significant surface water bodies at the Project site.
The location of the proposed infrastructure will not impact any watercourse or drainage area.
Rainfall runoff, and incident rainfall collected in the open pit will be pumped to the HDPE lined process water pond
Daily inspections of the process water pond and environmental dam will be undertaken to ensure adequate freeboard is maintained.
The process water pond and dam have been designed to accommodate a 1 in 100 year, 72 hour rainfall event.
Daily inspections of the surface water pipelines will be undertaken.
The management measures outlined in Section 6.5 and Section 6.6 will further assist in reducing the potential impacts on surface water.

6.4 GROUNDWATER
The Project is not located within a Proclaimed Groundwater Area under the Rights in Water and Irrigation Act 1914. There are no public drinking water sources within the vicinity of the Project.
Groundwater in the general Project area is limited. No groundwater will be used or intercepted by the Project.
The Project’s water will be solely obtained via mains (scheme) water supply and collected rainfall runoff, thus no groundwater is required.
All water collected in the pit (incident rainfall) will be pumped to the process water dam.
All hydrocarbons will be stored in bunded areas or on drip trays to contain any potential spills.
The Project is not expected to have any significant impact on local groundwater resources.
The management measures outlined in Section 6.5 and Section 6.6 will further assist in reducing the potential impact that the Project may have on groundwater.
6.5 SOLID AND LIQUID WASTE MANAGEMENT
All putrescible and industrial waste products, generated during operations, will be stored in appropriate containers and bulk/rubbish bins for general and domestic wastes and removed offsite on a regular basis and disposed of at the Cunderdin Shire landfill facility.
Scrap metal will be collected by a contractor and transported off site to a recycling yard.
Waste oil and other hydrocarbons will be collected and stored in a waste oil tank that meets the requirements for the storage of dangerous goods, prior to removal from site by an approved contractor for re-use or other approved form of disposal at a licenced facility. Transport of hydrocarbons offsite will comply with the Environmental Protection (Controlled Waste) Regulations 2004.
All other hydrocarbon contaminated materials (i.e. oil filters and hydrocarbon contaminated rags) will be disposed of into an approved receptacle which will then be removed and transported offsite for recycling or disposal.
Sewage will be disposed of via septic tanks and leach drains.
6.6 DANGEROUS GOODS AND HAZARDOUS SUBSTANCES
Dana will conduct its operations in a manner so as to minimise the risk of pollution arising from a chemical or reagent spill. Potential hazards could arise from the use and storage on-site of chemicals and hydrocarbons.
The following management measures have been identified to deal with potential hazards:
All hydrocarbons and dangerous goods on site will be stored and handled according to the applicable Dangerous Goods Safety Act 2004, Dangerous Goods Safety (Storage and Handling of Non-Explosives) Regulations 2007 and Dangerous Goods Safety (Explosives) Regulations 2007.
All diesel storage tanks will be double-skinned or contained within a bunded facility and comply with the Dangerous Goods Safety Act 2004 and the Dangerous Goods Safety (Storage and Handling of Non-explosives) Regulations 2007.
Waste oil and other hydrocarbons will be collected and stored in waste oil tanks that meet the applicable requirements for the storage of dangerous goods, prior to removal from site by an approved contractor for re-use or other approved form of disposal.
39
Spill response equipment will be stored in all workshops and on maintenance/service vehicles. If an inadvertent spillage of hydrocarbon occurs, the spill will be contained as much as possible by the use of the spill response equipment. In the event of a large spill, earthmoving equipment will construct earthen bunds to contain the spill. All surface oil will be collected for disposal. The contaminated soil will be removed, collected and transported off-site.
Used oils and hydrocarbon affected materials (oily rags, filters, etc.) will be collected and transported offsite to a licensed recycling facility.
All environmentally hazardous materials to be used will be stored in fenced and locked storage sites or storage cabinets in accordance with the Dangerous Goods Safety (Storage and Handling of Non-Explosives) Regulations 2007 and the Dangerous Goods Safety Act 2004.
6.7 DUST
Water trucks with dribble bars are utilised on site haul roads, plant area, ROM and access roads to control dust as required.
Dana has allowed contingency for use of Gluon on the ROM stockpiles if dust from these stockpiles poses an issue.
The movement of heavy vehicles will be restricted to existing tracks and the maximum speed for all vehicles is limited to 50 km/h.
Dust will be minimised at the screening plant with the use of bag houses and water sprays on the conveyor.
The closest residences are located >2km from the Project, thus, no impact related to dust on regional residents is anticipated.
6.8 GASEOUS ATMOSPHERIC EMMISSIONS
As part of the National Pollutant Inventory (NPI) and National Greenhouse and Energy Reporting System (NGERS), quantities of air and ground emissions will be estimated or measured and reported annually as required. This will include emissions from various activities at the site including ore crushing, vehicle movements and wind erosion.
Gaseous emissions from the project will comprise exhaust emissions from the diesel generators and the power station.
These emissions will not have a significant impact on the local or regional air quality.
All vehicles and machinery will be regularly serviced to minimise the emissions of combustion gases.
6.9 NOISE
The closest residences are located >2km from the Project, thus, no impacts related to noise are anticipated.
Personal protective equipment is provided to personnel who are working in an area where they may be at risk of exposure to noise hazards.
All mining operations comply with the noise regulations under the Mines Safety and Inspection Act 1994, Mines Safety and Inspection Regulations 1995 and the Environmental Protection (Noise) Regulations 1997.
6.10 LIGHT
The closest residences are located >2km from the Project, thus, thus no impacts related to light are anticipated.
40
6.11 ODOUR
The closest residences are located >2km from the Project, thus, thus no impacts related to odour are anticipated.
The septic system leach drains will be encased within and covered by rock or soil to reduce the potential for surface expression of the sewage. Consequently, the potential for odour impacts to occur are reduced.
The sludge from the septic tanks will be removed by an approved contractor to a licensed facility on a regular basis.
6.12 WORKFORCE INDUCTION AND TRAINING
All of the workforce, both staff and contractors, will be given comprehensive safety, occupational health, fire education and environmental inductions prior to commencing work at the site.
6.13 REHABILITATION
It is envisaged that the project site will return to agricultural land use when operations cease.
Dana has developed a Mine Closure Plan and all closure works will be undertaken in accordance with this plan.
