1. Introduction

1.1 Background

Strike South West Pty Ltd (hereafter referred to as Strike Energy) is proposing to drill the onshore Walyering 5 exploration well in the Shire of Dandaragan, in the Midwest region of Western Australia (WA) within petroleum exploration permit EP 447 (the Project). The Project Area is located approximately 22 km west of the Dandaragan, and 143 km north of Perth.

The purpose of the Project is to intersect and test the gas reservoir of the early Jurassic Age (Pleinsbachian and Toarcian) Cattamarra Coal Measures (A Sands and B Sands) formation in the north Perth Basin.

This Project involves the drilling and testing of the well only. It does not include any hydraulic fracturing or production activities. The Project Area is located on private land which has been previously cleared for agricultural purposes and no clearing of native vegetation is required to facilitate the Project.

1.2 Purpose and Scope

An Environment Plan (EP) has been prepared for the management of environmental aspects associated with the Project. The EP has been prepared in accordance with Regulation 11 (7) of the Petroleum and Geothermal Energy Resources Act 1967 (PGER Act) and in consideration of the Department of Mines, Industry Regulation and Safety (DMIRS) Guideline for the Development of Petroleum and Geothermal Environment Plans in Western Australia - November 2016.

This EP Summary document summarises the operations as well as the management and mitigation measures in the Environment Plan, including:

• The contact details of the operator/nominated liaison of the activity person for the Project;

• The location of the activity including coordinates and locality maps of the Project;

• A description of the existing environment that may potentially be affected by the Project;

• The operational details of the Project and proposed timing;

• The environmental impacts and environmental risks of the Project;

• The implementation strategy included in the Environment Plan; and

• Stakeholder consultation.

1.3 Proponent and Contact Details

The Proponent, Strike South West Energy, hereafter referred to as ‘Strike Energy,’ is a wholly-owned subsidiary of Strike Energy Limited, a publicly-listed oil and gas company with multiple exploration and production assets in WA and South Australia.

2.1 Project Overview

The Project will comprise the following stages, which are described in-depth further below:

• Geotechnical investigations, ground-truthing and site preparation;

• Mobilisation of equipment;

• Drilling and completion of the well;

• Well testing;

• Well suspension;

• Demobilisation of equipment and rehabilitation; and

• Post-rehabilitation monitoring.

2.2 Geotechnical/Ground-truthing Investigations

Minor ground-truthing will be required to determine construction requirements and accurately locate and demarcate all areas of construction and area that need to be avoided prior to site preparation. These investigations may require minor ground disturbance, including, for example, digging shallow pits to determine soil composition.

2.2.1 Site Preparation

Site preparation activities that may be required include the following:

• Surveying activities prior to breaking ground to delineate work areas;

• Installation of at least one downstream groundwater monitoring bore;

• Construction of site access road permitting passage of heavy goods vehicles and relatively long and/or wide loads during mobilisation and demobilisation;

• Construction of a well site with a surrounding fire management area including:

o bulk earthworks;

o final earthworks trim;

o generation of water storage and drill mud storage ponds/nests/sumps;

o pond lining;

o fencing; and

o signage.

2.3 Mobilisation of Equipment

A range of vehicles, machinery and equipment will be required on-site for the Project. Vehicles will access the site using public roads and a private farm road, turning off Brand Highway, then by driving along the Project access track into the Walyering 5 well site. A ring track will also be constructed within the well site layout to provide a turning radius for large vehicles (e.g., trucks).

All vehicles machinery and equipment entering the Project Area will be subject to hygiene controls to prevent the spread of weeds.

2.4 Drilling and Completion Well

The well will be drilled using standard onshore drilling techniques that are consistent with industry best practice. Drilling operations will be conducted within the well site, which is designed to contain

Page 11: Waylering 5 Exploration Well EP Summary

©JBS&G Australia Pty Ltd T/A Strategen-JBS&G WAY05-HSE-PLN-005 7

most of the equipment and infrastructure required for the drilling operation and will be surrounded by a 20 m wide cleared fire management area. The primary targets for Walyering 5 is the early Jurassic Age (Pleinsbachian and Toarcian) Cattamarra Coal Measures (A Sands and B Sands) formation. The well will be drilled to approximately 3 252 m depth to intercept all targets.

All chemicals proposed for use in drilling will be approved by DMIRS prior to use and are disclosed in Strike’s Chemical Disclosure document (Appendix A), in accordance with the DMIRS Chemical Disclosure Guideline (DMP 2013).

2.5 Well Perforation and Well Testing

If drill cuttings, logs and/or side-wall cores acquired during drilling show favourable results, well testing will subsequently be performed to assess flow and reservoir and characteristics. No fracture stimulation is proposed.

Strike Energy will construct two flare pits during the well activity. The first (a small fare pit) flare pit will be constructed during initial civil works for use during drilling in the event of a kick or well control incident as is required by Strike Energy as the operator. For the well test, a second flare pit will be constructed by repurposing the turkey’s nest used during drilling. The liner from the old turkey’s nest will be removed, and the turkey's nest will be excavated to a depth of approximately 1 m below ground level.

Relevant authorities will be notified (including DMIRS and local/regional premises of the Department of Fire and Emergency Services (DFES)) during operations when flaring is expected to occur. Other stakeholders (e.g., landholders/owners), will also be notified where appropriate.

2.6 Well Suspension

Following production testing, Walyering 5 will be suspended until the results of the test have been analysed and any further well operations, suitable long term production opportunities, or further exploration opportunities, are identified.

If Strike Energy determines to proceed beyond the production testing phase in the future, these activities will be subject to further approvals by the relevant agencies at that time.

2.7 Demobilisation

Following a decision to decommission and suspend (or abandon) Walyering 5, the well will be left in a state that is in accordance with the relevant regulations. Infrastructure will be removed, and equipment will be demobilised. All areas disturbed by the Project will be returned to pre-disturbance condition or otherwise in accordance with access agreements.

2.8 Post-rehabilitation Monitoring

2.8.1 Groundwater

A Groundwater Monitoring Plan (GWMP) has been prepared which details how groundwater monitoring will be undertaken throughout the Project lifecycle. The proposed groundwater monitoring program will continue for the duration of the Project. Quarterly monitoring will cease after completion of the exploration drilling if no impact has been identified and up to two (2) years if an impact has been identified.

2.8.2 Rehabilitation

Strike Energy will implement a rehabilitation monitoring program after demobilisation is completed to ensure that the site is comparable to its pre-disturbance condition and in accordance with landowner access agreements.

3. Existing Environment

3.1 Regional Context

The Project area is located in the Perth subregion (SWA02) of the Swan Coastal Plain bioregion and the Lesueur Sandplain subregion (GS3) of the Geraldton Sandplains bioregion as defined by the Interim Biogeographic Regionalisation for Australia (IBRA). The Lesueur Sandplain subregion (GS3) comprises coastal Aeolian and limestones, Jurassic siltstones and sandstones (often heavily lateritised) of central Perth Basin (Desmond & Chant, 2001).

The climate of the Project Area and the broader region is described as a Mediterranean climate: warm, dry summer seasons, and cool, mildly wet winter seasons. The nearest open weather station is Badgingarra Research Station (Site No. 9037), which is approximately 39 km north of the Project which shows the warmest period typically occurs between December to February, whereas the coolest period is experienced between June to August. (Bureau of Meteorology 2021).

3.2 Geology, Landform, and Soils

The Project Area is located within the Swan Coastal Plain geomorphological division. The Swan Coastal Plain comprises five major geomorphic systems that lie parallel to the coast, namely (from west to east), the Quindalup Dune, Spearwood Dunes, Bassendean Dunes, Pinjarra Plain, and Ridge Hill Shelf (McArthur 1980; Gibson et al. 1994). Soils in this region are described as mainly sandy yellow sands. This region is almost completely underlain by sedimentary rocks of siliceous nature. The sedimentary rocks form a series of plateaux, including the Dandaragan Plateau, on which the Project is located. These plateaux have been eroded by the sea on the west and dissected by rivers, but substantial stretches of the plateau surfaces are still preserved and form extensive monotonous sandplains (Beard 1990; Eco Logical 2019).

A review of the Australian Soil Resources Inquiry System database indicated the Acid Sulphate Soil Probability to be “Extremely Low Probability of Occurrence” within the Project Area

The topography of Project Area is generally flat with the elevation dropping gently away to the west of the Project Area, toward the coast.

3.3 Regional Hydrology

3.3.1 Surface Hydrology

There are two significant surface water features within in proximity to the Project Area – Minyulo Brook and Caro Swamp (Figure 2.1).

Minyulo Brook is a minor, non-perennial, dissecting watercourse which is bridged by the pre-existing infrastructure (access tracks) used by the landowner.

Caro Swamp is also located approximately 0.27 km southwest of the Project Area. The swamp is a catchment for several minor, non-perennial watercourses including Caro Brook, Eneminga Brook, and Minyulo Brook.

Wetlands within and surrounding the Project Area form an element of the Minyulo Suite, which are a group of consanguineous wetlands comprising Mullering and Minyulo brooks, Emu Lakes and smaller sumplands, damplands and seasonal creeks located between brooks within the Bassendean dunes (Figure 2.1). Typical surface water within this suite ranges from fresh to hyposaline with pH ranging from 6.9 – 10. Mullering and Minyulo brooks are both regionally significant as they support a high proportion of water dependent flora and act as a flushing mechanism for associated wetlands.

A large portion of the land in the vicinity of the Project Area is subject to inundation; however, the likelihood of this occurring is low, based on the climate statistics of the region and the low likelihood of a highly extensive and localised storm event (100-year storm) [Desmond 2001]. Caro Swamp and adjacent areas are likely to be seasonally inundated.

Page 16: Waylering 5 Exploration Well EP Summary

3.3.2 Groundwater

The largest fresh groundwater resources within the north Perth Basin are in the Surficial, Leederville, Leederville-Parmelia and Yarragadee aquifers. There are also three (3) secondary aquifers: The Mirrabooka; Cattamarra and Eneabba-Lesueur aquifers. In addition to these groundwater resources, there are minor shallow and fractured-rock aquifers that are locally significant sources of water. Hydraulic connection between aquifers is often impeded across faults and low permeability units, both within and between aquifers (DoW 2017).

Groundwater is contained within superficial aquifers including the Leederville and Leederville-Parmelia aquifer east of the Project Area, and the Yarragadee aquifer on the coastal plain and the Dandaragan Land System (DoW 2017). Groundwater is understood to be relatively shallow, with a depth of ≤ 20 mbgl and the groundwater quality in the broader regional area is understood to be marginal, with a salinity of 500 – 1000 mg/L (as per the Perth Groundwater Map from DWER).

The Leederville aquifer comprises sandstone and shale, with a thickness of up to 550 m. The aquifer is ‘semi-confined’ to ‘confined’ with a generally fresh (≤ 1000 µS/cm). The Leederville-Parmelia aquifer consists of the interconnected Leederville formation and the Parmelia Group, comprising sandstone and shale. The aquifer is ‘semi-confined’ to the north becoming confined to the south with generally fresh groundwater quality. The Yarragadee Formation comprises sand, shale, and siltstone. The aquifer is ‘unconfined’ to ‘confined’ with generally fresh groundwater quality.

3.4 Air and Noise Emissions

Ambient air quality in the vicinity of the Project area is expected to be representative of surrounding dust generating activities being primarily pastoral and tourism activities, use of agricultural machinery and vehicle movements.

The Project will give rise to atmospheric emissions because of the operation of combustion-engine vehicles, equipment and/or machinery, and generators. These emissions are not expected to cause a reduction in local air quality; therefore, they are considered comparable to emissions from existing activities in the area.

Ambient noise levels in the vicinity of the Project Area are expected to be affected by industrial, pastoral, and/or tourism activities. These sources of emissions are anticipated to have a relatively low or insignificant impact on the overall noise levels in the local area.

Activities associated with the Project generate noise emissions like rural plant and machinery use activities. The drilling rig may produce higher-than-average levels of noise, particularly associated with well flaring and testing.

The Project will be conducted in accordance with the Environmental Protection (Noise) Regulations 1997 (Noise Regulations).

3.5 Flora and Vegetation

3.5.1 Native Vegetation

The Project Area is located entirely within pre-existing cleared areas used for agricultural activities. No clearing of conservation significant flora and/or native vegetation is required. Caro Swamp and the surrounding dissecting watercourses in the vicinity of the Project Area comprise intact native vegetation (conservation significant flora may also be present).

Database searches were undertaken to generate a list of vascular flora and Threatened, and Priority Ecological Communities (TEC/PEC) previously recorded within and nearby the Project Area.

The Project is located within the Irwin Botanical District, within the Southwest Botanical Province (Beard 1990). Plants within this district are predominantly from the Proteaceae (Grevillea, Banksia),

Page 17: Waylering 5 Exploration Well EP Summary

©JBS&G Australia Pty Ltd T/A Strategen-JBS&G WAY05-HSE-PLN-005 13

Myrtaceae (Eucalyptus, Melaleuca), Fabaceae (Acacia), Casuarinaceae (Casuarina, Allocasuarina), Chenopodiaceae (salt bushes), Poaceae (grasses) and annually, Asteraceae (daisies) families.

At a vegetation association level, two (2) Beard (1981) associations are mapped within the Project Area, including:

• Bassendean 1030: Mosaic-Shrublands-hakea scrubheath/Shrublands, banksia heath – Other acacia, banksia, peppermint, cypress pine, casuarina, York gum Acacia spp., Banksia spp., Agonis flexuosa, Callitris spp., Allocasuarina spp., Eucalyptus loxophleba; and

• Bassendean 1031: Low woodland; Banksia attenuata and B. menziesii – Scrub heath/Heath.

3.5.1.1 Threatened and Priority Flora

The Project will only be undertaken within previously cleared areas which have been used extensively for agricultural purposes and therefore, threatened or priority flora species that may possibly occur in the area will not be directly impacted by the Project.

Indirect impacts to flora and vegetation are also not expected given the well pad location is 150 m from the closest patch of remnant vegetation and the range of management measures which will be implemented to mitigate the potential for indirect impacts.

3.5.1.2 Threatened and Priority Species and Ecological Communities

No Threatened or Priority Ecological Communities (TECs/PECs) occur within the Project Area. Two (2) TECs, Banksia Woodlands of the Swan Coastal Plain, and Tuart (Eucalyptus gomphocephala) Woodlands and Forests of the Swan Coastal Plain ecological communities may occur in the surrounding area; however, the Project will only be undertaken within previously cleared areas and therefore, no impacts to these ecological communities are anticipated.

3.5.2 Weeds The Project Area is located entirely within pre-existing cleared areas used for agricultural activities. If circumstances lead to the landowner(s) recognising a plant species outside of the species they have sown, management action will be undertaken to remove the weed(s) without worsening the environmental situation and/or the soil quality.

3.5.3 Phytophthora cinnamomi (Dieback)

The Project Area is located entirely within pre-existing cleared areas used for agricultural activities; therefore, the land can be allocated the status of ‘unprotectable’ as no native vegetation that is at risk of being infested exists within the Project Area.

3.5.4 Potential Impact to Vegetation

No clearing of native vegetation is required for the Project activities. All Project activities will be limited to pre-existing cleared areas, public roads, cleared tracks and firebreaks. No impacts to native vegetation are planned. The overall risk of Project activities to vegetation and flora, including conservation significant flora is low.

3.6 Fauna

Database searches were undertaken to generate a list of conservation significant vertebrate fauna, previously recorded within, and in proximity to the Project Area.

Based on previous assessments and an updated desktop assessment for the Project Area (including a recent search for Matters of National Environmental Significance (MNES)) under the EPBC Act (including a 10 km buffer around the Project Area), several listed conservation significant fauna may be present in the uncleared land in the vicinity of the Project Area. Table 3.1 lists those species likely to occur within the Project Area.

The Project Area is located entirely within pre-existing cleared areas used for agricultural activities; therefore, the land expected to have limited habitat value for native fauna. No clearing of faunal habitat is required for the Project.

Wetlands within and surrounding the Project Area form an element of the Minyulo Suite, which are a group of consanguineous wetlands comprising Mullering and Minyulo brooks, Emu Lakes and smaller sumplands, damplands and seasonal creeks located between brooks within the Bassendean dunes.

A large portion of the land in the vicinity of the Project Area is subject to inundation; however, the likelihood of this occurring is low, based on the climate statistics of the region and the low likelihood of a highly extensive and localised storm event (100-year storm) [Desmond 2001]. Caro Swamp and adjacent areas are likely to be seasonally inundated.

The most at risk fauna will be birds and reptiles, which may be attracted to the onsite open water storage and/or the putrescible waste produced by the Project. Egress matting is intended to be installed to enable ground-dwelling fauna (i.e., reptiles) to escape from water storage ponds. All wastes will be stored in bins with securely fitting lids for offsite disposal.

Cattle (Bos taurus taurus), Sheep (Ovis aries) and/or other livestock may be present in the vicinity of the Project Area. Fencing and cattle grids are proposed to be installed to limit the opportunity for access by livestock to the Project Area. Fencing is also designed to limit the access of larger, potentially more mobile, fauna species (e.g., Western Grey Kangaroos (Macropus fuliginosus) from entering the Project Area. A relatively low speed limit (e.g., 30 km/hr) will be used on the access track within the Project Area by all vehicles to reduce the risk of fauna strike.

The most at risk fauna will be birds and reptiles, which may be attracted to the onsite open water storage and/or the putrescible waste produced by the Project. Egress matting is intended to be installed to enable ground-dwelling fauna (i.e., reptiles) to escape from water storage ponds. All wastes will be stored in bins with securely fitting lids for offsite disposal.

4. Socio-Economic Environment

The Project Area is located within the Shire of Dandaragan on a private land. The Shire of Dandaragan has an estimated resident population of 3,266 which is spread across four major townships (Badgingarra, Cervantes, Dandaragan, and Jurien Bay) [Australian Bureau of Statistics 2019]. The nearest towns are Cataby (5.7 km east) and Dandaragan (22 km northeast). The nearest residences in proximity to the well are 2.34 km east-southeast; 4.67 km east north east.

The dominant industries within the Shire of Dandaragan are agriculture and pastoralism, broadacre farming, fishing (i.e., the Western Rock Lobster), mining, and tourism.

4.1 Native Title

The Project Area is located within the Yued registered Native Title Claim area. The South West Aboriginal Land and Sea Council (SWALSC) is the native title representative body. Strike Energy has signed a Heritage Protection Agreement, carried over from the previous operator of EP 447 (Pancontinental Oil & Gas NL) on 30 November 2016, with SWALSC on behalf of the Yued Agreement Group.

Strike Energy, as the operator of EP 447, will continue to consult and engage with these stakeholders to implement the Cultural Heritage Management Plan, and amend as appropriate, and ensure an appropriate level if awareness of all Strike Energy personnel and contractors with respect to cultural heritage matters.

4.2 Aboriginal Heritage

No Registered Aboriginal Sites or Other Heritage Places occur within the Project Area. One (1) site is located approximately 0.37 km southwest from the Project Area, Minyulo Brook (Bilya) – Site ID 28326 (Arch Deposit; Artefacts/Scatter; Birthplace; Camp; Ceremonial; Hunting Place; Modified Tree; Mythological; Natural Feature; Plant Resource; and Water Source). This site will not be impacted by the Project. In the event of a discovery or the identification of an object reasonably suspected of being an Aboriginal artefact a “Stop Work” procedure, including notification and reporting, will apply will be implemented.

4.3 European Heritage / Geo-heritage

No significant European or geo-heritage sites occur within the Project Area.

Page 41: Waylering 5 Exploration Well EP Summary

Ecotoxicity Data: In short-term acute toxicity tests with fish, daphnia and algae the following results were found (lowest test result values): Ictalurus punctulus 48h-LC50 = 720 mg/l; Daphnia magna: 48h-LC50 = 177 mg/l; Nitzschia linearis: 120 h-EC50 = 1337 mg/l. A chronic reproductive test with the invertebrate Daphnia magna gave a LOEC of 101 mg/l. All the studies compiled on the acute and chronic aquatic toxicity were > 100 mg/L. Thus it is concluded that KCl is not hazardous to freshwater organisms. Taking into considerations the background concentrations of KCl in seawater (380 mg/l K+ and 19,000 mg/l Cl-), it is concluded that there is no reason for further investigations of KCl on marine species. The low concern for the environment is supported by the absence of a bioaccumulation potential for the substance.

16. OTHER INFORMATION

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established onthe premise of an 8 hour work period of normal intensity, under normal climatic conditions and wherea 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In thefollowing circumstances, exposure standards must be reduced: Strenuous work conditions; hot,humid climates; high altitude conditions; extended shifts (which increase the exposure period andshorten the period of recuperation).

4.3 Immediate medical attention and special treatment neededCORROSIVE POISONING TREATMENT: Immediate treatment preferably in a hospital is mandatory. In treating corrosive poisoning,DO NOT INDUCE VOMITING; DO NOT ATTEMPT GASTRIC LAVAGE; and DO NOT ATTEMPT TO NEUTRALISE THE CORROSIVESUBSTANCE. Vomiting will increase the severity of damage to the oesophagus as the corrosive substance will again come in contactwith it. Attempting gastric lavage may result in perforating either the oesophagus or stomach. Immediately dilute the corrosivesubstance by having the patient drink milk or water. If the trachea has been damaged tracheostamy may be required. Foroesophageal burns begin broad-spectrum antibiotics and corticosteroid therapy. Intravenous fluids will be required if oesophageal orgastric damage prevents ingestion of liquids. Long-range therapy will be directed toward preventing or treating oesophageal scars andstrictures.

Eye Causes severe burns. Contact may result in irritation, lacrimation, pain, redness and corneal burns withpossible permanent eye damage.

Sensitization This product is not known to be a skin or respiratory sensitiser.

Over exposure may result in irritation of the nose and throat, with coughing. High level exposure may result inbreathing difficulties.

STOT – singleexposure

Aspiration This product does not present an aspiration hazard.

Not classified as causing organ effects from repeated exposure.STOT – repeatedexposure

Reproductive Insufficient data available to classify as a reproductive toxin. The substance is not expected to besystemically available in the body under normal handling and use conditions and for this reason it can bestated that the substance will not reach the foetus nor reach male and female reproductive organs. Thesubstance is not expected to be systemically available in the body under normal handling and use conditionsand for this reason additional testing is considered unnecessary.

Carcinogenicity Insufficient data available to classify as a carcinogen. Systemic carcinogenicity is not expected to occurbecause the substance is not expected to be systemically available in the body under normal handling anduse conditions.

Mutagenicity Insufficient data available to classify as a mutagen. Both the in vitro and the in vivo genetic toxicity testsindicated no evidence of mutagenic activity. Furthermore the substance is not expected to be systemicallyavailable in the body under normal handling and use conditions and for this reason additional testing isconsidered unnecessary (EU RAR, 2007).

11.1 Information on toxicological effects

12. ECOLOGICAL INFORMATION

12.1 Toxicity

EC50 Ceriodaphnia: 40 mg/L.

No other valid studies available. The hazard of NaOH for the environment is caused by the hydroxyl ion (pH effect). For this reason theeffect of NaOH on the organisms depends on the buffer capacity of the aquatic or terrestrial ecosystem (see also 3.1.2). Also thevariation in acute toxicity for aquatic organisms can be explained for a significant extent by the variation in buffer capacity of the testmedium. LC50 values ranged between 33 and 189 mg/L.

12.2 Persistence and degradabilityReadily biodegradable. NaOH is a strong alkaline substance that dissociates completely in water to Na+ and OH-. High water solubilityand low vapour pressure indicate that NaOH will be found predominantly in aquatic environment. This implies that it will not adsorb onparticulate matter or surfaces. Atmospheric emissions as aerosols are rapidly neutralized by carbon dioxide and the salts will bewashed out by rain.

12.4 Mobility in soil

High water solubility and mobility

12.5 Other adverse effects

WATER: If released to waterways, alkaline products may change the pH of the waterway. Fish will die if the pH reaches 10-11(goldfish 10.9, bluegill 10.5). SOIL: May leach to groundwater with toxic effects on aquatic life as above. ATMOSPHERE: Not expectedto reside in the atmosphere. Drops or particles released to atmosphere should be removed by gravity and/or be rained out.

12.3 Bioaccumulative potentialDoes not bioaccumulate. Considering its high water solubility, NaOH is not expected to bioconcentrate in organisms. In addition,sodium is a naturally-occurring element that is prevalent in the environment and to which organisms are exposed regularly, for whichthey have some capacity to regulate the concentration in the organism.

EXPOSURE CONTROL: If utilised in a closed system the potential for over exposure is reduced. Ifnot used in a closed system, local exhaust ventilation is recommended to control exposure. Provideeye wash and safety shower in close proximity to points of potential exposure. Where the potentialfor an inhalation risk exists, an approved respirator may be required. Do not eat, store, consumefood, tobacco or drink in areas where product is used.

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

16. OTHER INFORMATION

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established onthe premise of an 8 hour work period of normal intensity, under normal climatic conditions and wherea 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In thefollowing circumstances, exposure standards must be reduced: Strenuous work conditions; hot,humid climates; high altitude conditions; extended shifts (which increase the exposure period andshorten the period of recuperation).

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as method of application, working environment, quantity used, productconcentration and the availability of engineering controls should be considered before final selectionof personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE:It should be noted that the effects from exposure to this product will depend on several factorsincluding: frequency and duration of use; quantity used; effectiveness of control measures; protectiveequipment used and method of application. Given that it is impractical to prepare a ChemAlert reportwhich would encompass all possible scenarios, it is anticipated that users will assess the risks andapply control methods where appropriate.

16. OTHER INFORMATION

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established onthe premise of an 8 hour work period of normal intensity, under normal climatic conditions andwhere a 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants.In the following circumstances, exposure standards must be reduced: Strenuous work conditions;hot, humid climates; high altitude conditions; extended shifts (which increase the exposure periodand shorten the period of recuperation).

COMBUSTIBLE - EXPLOSIVE CARBONACEOUS DUST: Carbonaceous/organic dusts have thepotential, with dispersion, to present an explosion hazard if an ignition source exists. All equipmentused to handle, transfer or store this product MUST BE cleaned thoroughly prior to cutting, welding,drilling or exposure to any other form of heat or ignition sources. If bulk stored, containers should beventilated on a routine basis to avoid vapour accumulation (where applicable, eg for flocculants).

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as form of product, method of application, working environment, quantity used,product concentration and the availability of engineering controls should be considered before finalselection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE:It should be noted that the effects from exposure to this product will depend on several factorsincluding: form of product; frequency and duration of use; quantity used; effectiveness of controlmeasures; protective equipment used and method of application. Given that it is impractical toprepare a report which would encompass all possible scenarios, it is anticipated that users willassess the risks and apply control methods where appropriate.

Version No: 2.1

Page 169: Waylering 5 Exploration Well EP Summary

POTASSIUM CHLORIDEPRODUCT NAME

LDLo (Intraperitoneal): 900 mg/kg (guinea pig)LDLo (Intravenous): 77 mg/kg (guinea pig)LDLo (Subcutaneous): 2120 mg/kg (frog)TDLo (Ingestion): 60 mg/kg/days (woman)

Skin Not classified as a skin irritant. Contact may result in mild irritation and rash.

Eye Not classified as an eye irritant. Contact may cause mild irritation and lacrimation.

Sensitization This product is not known to be a skin or respiratory sensitiser.

Acute potassium poisoning via ingestion is rare as a large single dose usually induces vomiting, andpotassium is rapidly excreted by the body, however this product does have the potential to causecardiovascular disorders.

STOT – singleexposure

Aspiration Not relevant.

Not classified as causing organ effects from repeated exposure.STOT – repeatedexposure

Reproductive No evidence of reproductive effects.

Carcinogenicity No evidence of carcinogenic effects.

Mutagenicity No evidence of mutagenic effects.

12. ECOLOGICAL INFORMATION

12.1 Toxicity

In short-term acute toxicity tests with fish, daphnia and algae the following results were found (lowest test result values): Ictaluruspunctulus 48h-LC50 = 720 mg/l; Daphnia magna: 48h-LC50 = 177 mg/l; Nitzschia linearis: 120 h-EC50 = 1337 mg/l. A chronicreproductive test with the invertebrate Daphnia magna gave a LOEC of 101 mg/l. All the studies compiled on the acute and chronicaquatic toxicity were > 100 mg/L. Thus it is concluded that KCl is not hazardous to freshwater organisms. Taking into considerationsthe background concentrations of KCl in seawater (380 mg/l K+ and 19,000 mg/l Cl-), it is concluded that there is no reason for furtherinvestigations of KCl on marine species. The low concern for the environment is supported by the absence of a bioaccumulationpotential for the substance.

12.2 Persistence and degradabilityBiodegradability does not pertain to inorganic substances.

12.4 Mobility in soil

No impact if small amount is released to the soil.

12.5 Other adverse effects

No information provided.

12.3 Bioaccumulative potentialDoes not bioaccumulate.

13. DISPOSAL CONSIDERATIONS

Waste disposal Collect and place in sealable containers and dispose of to an approved landfill site. Contact themanufacturer/supplier for additional information (if required).

16. OTHER INFORMATION

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

WORKPLACE CONTROLS AND PRACTICES: Unless a less toxic chemical can be substituted for ahazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure.The best protection is to enclose operations and/or provide local exhaust ventilation at the site ofchemical release. Isolating operations can also reduce exposure. Using respirators or protectiveequipment is less effective than the controls mentioned above, but is sometimes necessary.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as method of application, working environment, quantity used, productconcentration and the availability of engineering controls should be considered before final selectionof personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE:It should be noted that the effects from exposure to this product will depend on several factorsincluding: frequency and duration of use; quantity used; effectiveness of control measures; protectiveequipment used and method of application. Given that it is impractical to prepare a report whichwould encompass all possible scenarios, it is anticipated that users will assess the risks and applycontrol methods where appropriate.

16. OTHER INFORMATION

The manufacturer indicates the product is mixture of 30-50% Hexanedinitrile, 5-20% Hydrochloricacid (as pH corrector) and water. Hydrochloric acid is used to neutralise hexanedinitrile to becomethe salt with slightly alkali (pH 9-11).

AMINE: CAUTION THIS PRODUCT CONTAINS AN AMINE. DO NOT ADD NITRITES or otherNITROSATING AGENTS to this product due to the potential for NITROSAMINE formation.Nitrosamines are potent carcinogens and some have been shown to cause severe acute (heart,brain, blood, liver - kidney) damage as well as chronic effects (reproductive effects, liver - lung andkidney tumours).

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGE (TWA) or WES (WORKPLACEEXPOSURE STANDARD) (NZ): Exposure standards are established on the premise of an 8 hourwork period of normal intensity, under normal climatic conditions and where a 16 hour breakbetween shifts exists to enable the body to eliminate absorbed contaminants. In the followingcircumstances, exposure standards must be reduced: strenuous work conditions; hot, humidclimates; high altitude conditions; extended shifts (which increase the exposure period and shortenthe period of recuperation).

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as method of application, working environment, quantity used, productconcentration and the availability of engineering controls should be considered before final selectionof personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE:It should be noted that the effects from exposure to this product will depend on several factorsincluding: frequency and duration of use; quantity used; effectiveness of control measures;protective equipment used and method of application. Given that it is impractical to prepare aChemAlert report which would encompass all possible scenarios, it is anticipated that users willassess the risks and apply control methods where appropriate.

16. OTHER INFORMATION

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established onthe premise of an 8 hour work period of normal intensity, under normal climatic conditions and wherea 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In thefollowing circumstances, exposure standards must be reduced: Strenuous work conditions; hot,humid climates; high altitude conditions; extended shifts (which increase the exposure period andshorten the period of recuperation).

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as method of application, working environment, quantity used, productconcentration and the availability of engineering controls should be considered before final selectionof personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE:It should be noted that the effects from exposure to this product will depend on several factorsincluding: frequency and duration of use; quantity used; effectiveness of control measures; protectiveequipment used and method of application. Given that it is impractical to prepare a ChemAlert reportwhich would encompass all possible scenarios, it is anticipated that users will assess the risks andapply control methods where appropriate.

16. OTHER INFORMATION

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established onthe premise of an 8 hour work period of normal intensity, under normal climatic conditions andwhere a 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants.In the following circumstances, exposure standards must be reduced: Strenuous work conditions;hot, humid climates; high altitude conditions; extended shifts (which increase the exposure periodand shorten the period of recuperation).

COMBUSTIBLE - EXPLOSIVE CARBONACEOUS DUST: Carbonaceous/organic dusts have thepotential, with dispersion, to present an explosion hazard if an ignition source exists. All equipmentused to handle, transfer or store this product MUST BE cleaned thoroughly prior to cutting, welding,drilling or exposure to any other form of heat or ignition sources. If bulk stored, containers should beventilated on a routine basis to avoid vapour accumulation (where applicable, eg for flocculants).

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES:The recommendation for protective equipment contained within this report is provided as a guideonly. Factors such as form of product, method of application, working environment, quantity used,product concentration and the availability of engineering controls should be considered before finalselection of personal protective equipment is made.

Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause aprogressive, disabling, and sometimes-fatal lung disease called silicosis.Symptoms include cough, shortness of breath, wheezing, non-specific chestillness, and reduced pulmonary function. This disease is exacerbated by smoking.Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) hasdetermined that crystalline silica inhaled in the form of quartz or cristobalite fromoccupational sources can cause lung cancer in humans (Group 1 - carcinogenic tohumans) and has determined that there is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (Group 2A - possible carcinogen tohumans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres(June 1997) in conjunction with the use of these minerals. The National ToxicologyProgram classifies respirable crystalline silica as "Known to be a humancarcinogen". Refer to the 9th Report on Carcinogens (2000). The AmericanConference of Governmental Industrial Hygienists (ACGIH) classifies crystallinesilica, quartz, as a suspected human carcinogen (A2). There is some evidencethat breathing respirable crystalline silica or the disease silicosis is associated withan increased incidence of significant disease endpoints such as scleroderma (animmune system disorder manifested by scarring of the lungs, skin, and otherinternal organs) and kidney disease.

11. Toxicological Information

Information on routes of exposure Principle Route of Exposure Eye or skin contact, inhalation.

Symptoms related to exposure

Most Important Symptoms/EffectsBreathing crystalline silica can cause lung disease, including silicosis and lung cancer. Crystalline silica has alsobeen associated with scleroderma and kidney disease.

Toxicology data for the components

Substances CAS Number LD50 Oral LD50 Dermal LC50 Inhalation

Crystalline silica, quartz 14808-60-7 > 15000 mg/kg (human) No data available No data available

Immediate, delayed and chronic health effects from exposure Inhalation Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is

carcinogenic to humans (IARC, Group 1). There is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (IARC, Group 2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages.Breathing silica dust may not cause noticeable injury or illness even though permanent lungdamage may be occurring. Inhalation of dust may also have serious chronic health effects(See "Chronic Effects/Carcinogenicity" subsection below).

Eye Contact May cause mechanical irritation to eye.Skin Contact None known.Ingestion None known.

Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause aprogressive, disabling, and sometimes-fatal lung disease called silicosis.Symptoms include cough, shortness of breath, wheezing, non-specific chestillness, and reduced pulmonary function. This disease is exacerbated by smoking.Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) hasdetermined that crystalline silica inhaled in the form of quartz or cristobalite fromoccupational sources can cause lung cancer in humans (Group 1 - carcinogenic tohumans) and has determined that there is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (Group 2A - possible carcinogen tohumans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres(June 1997) in conjunction with the use of these minerals. The National ToxicologyProgram classifies respirable crystalline silica as "Known to be a humancarcinogen". Refer to the 9th Report on Carcinogens (2000). The AmericanConference of Governmental Industrial Hygienists (ACGIH) classifies crystallinesilica, quartz, as a suspected human carcinogen (A2). There is some evidencethat breathing respirable crystalline silica or the disease silicosis is associated withan increased incidence of significant disease endpoints such as scleroderma (animmune system disorder manifested by scarring of the lungs, skin, and otherinternal organs) and kidney disease.

Exposure LevelsNo data available

Interactive effects Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not beexposed to quartz dust.

Immediate, delayed and chronic health effects from exposure Inhalation Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is

carcinogenic to humans (IARC, Group 1). There is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (IARC, Group 2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages.Breathing silica dust may not cause noticeable injury or illness even though permanent lungdamage may be occurring. Inhalation of dust may also have serious chronic health effects(See "Chronic Effects/Carcinogenicity" subsection below).

Eye Contact May cause mechanical irritation to eye.Skin Contact None known.Ingestion None known.

Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause aprogressive, disabling, and sometimes-fatal lung disease called silicosis.Symptoms include cough, shortness of breath, wheezing, non-specific chestillness, and reduced pulmonary function. This disease is exacerbated by smoking.Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) hasdetermined that crystalline silica inhaled in the form of quartz or cristobalite fromoccupational sources can cause lung cancer in humans (Group 1 - carcinogenic tohumans) and has determined that there is sufficient evidence in experimentalanimals for the carcinogenicity of tridymite (Group 2A - possible carcinogen tohumans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres(June 1997) in conjunction with the use of these minerals. The National ToxicologyProgram classifies respirable crystalline silica as "Known to be a humancarcinogen". Refer to the 9th Report on Carcinogens (2000). The American

Personal protective equipment (PPE) Personal Protective Equipment If engineering controls and work practices cannot prevent excessive exposures, the

selection and proper use of personal protective equipment should be determined by an industrial hygienist or other qualified professional based on the specific application of this product.

Respiratory Protection Not normally needed. But if significant exposures are possible then the following respirator is recommended: Dust/mist respirator. (N95, P2/P3)

Hand Protection Chemical-resistant protective gloves (EN 374) Suitable materials for longer, direct contact (recommended: protection index 6, corresponding to > 480 minutes permeation time as per EN 374): Nitrile gloves. (>= 8 mm thickness) This information is based on literature references and on information provided by glove manufacturers, or is derived by analogy with similar substances. Please note that in practice the working life of chemical-resistant protective gloves may be considerably shorter than the permeation time determined in accordance with EN 374 as a result of the many influencing factors (e.g. temperature). If signs of wear and tear are noticed then the gloves should be replaced. Manufacturer's directions for use should be observed because of great diversity of types.

16. OTHER INFORMATION

WORKPLACE CONTROLS AND PRACTICES: Unless a less toxic chemical can be substituted for ahazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure.The best protection is to enclose operations and/or provide local exhaust ventilation at the site ofchemical release. Isolating operations can also reduce exposure. Using respirators or protectiveequipment is less effective than the controls mentioned above, but is sometimes necessary.

RESPIRATORS: In general the use of respirators should be limited and engineering controlsemployed to avoid exposure. If respiratory equipment must be worn ensure correct respiratorselection and training is undertaken. Remember that some respirators may be extremelyuncomfortable when used for long periods. The use of air powered or air supplied respirators shouldbe considered where prolonged or repeated use is necessary.
