EXECUTIVE SUMMARY

The Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act) (Commonwealth

of Australia 2016) provides for the protection of environmental values, including matters of

national environmental significance (MNES). Under the EPBC Act, Senex were requested to

prepare a Public Environment Report (PER). Section 6 of the PER guidelines request a chemical risk

assessment for chemicals to be used in coal seam gas (CSG) extraction, in accordance with

national or international standards and guidelines.

Klohn Crippen Berger Ltd (KCB) were commissioned to undertake a chemical risk assessment for

chemicals to be used in CSG extraction as part of the Western Surat Gas Project (WSGP); a CSG

project in the Surat Basin region, Queensland. The assessment examined the risks associated with

use of drilling fluids and their associated chemicals only. This generally occurs during the initial

drilling, maintenance and decommissioning of CSG production wells.

The risk assessment was undertaken in four stages, adopting the guidance provided in the OECD

Risk Assessment Toolkit (OECD 2014), in an approach consistent with AS/NZS 4360:2004: Risk

Management and AS/NZS ISO 31000:2009 Risk Management – Principals and Guidelines (AS/NZS

2009, 2004). The four stages included hazard identification, hazard characterization, exposure

assessment and risk characterization.

Hazard identification involved identifying products and chemicals to be used during the drilling

process and assessing their hazardous nature. A drilling fluid was considered hazardous if it

triggers health hazard criteria, environmental health hazard criteria or has been identified as a

pollutant, contaminant or hazardous material. Where a drilling fluid was deemed to be potentially

hazardous, further hazard characterisation was undertaken. This considered the nature and state

of the chemicals at surface and their solubility, the fate and transport in the environment, as well

as an assessment of the proposed volumes of chemicals to be used. An exposure assessment then

identified the potential chemical sources and the ‘risk events’ which may result in their release to

the environment, and with consideration of the likely fate and transport, the likely exposure

pathways and potential impacts on MNES. Groundwater transport modelling using an industry

standard 1D analytical model was adopted to assess potential travel times and concentrations to

receptors from identified contaminants. As a final step, risk characterisation considered the

potential for (likelihood) and the magnitude (significance) of the risk to MNES from drilling fluids.

Risk ratings were determined, with regards to the significant impact guidelines and MNES, both

with, and without, the application of management and mitigation measures.

Sixteen chemicals were identified for potential use during drilling, management and

abandonment of CSG wells. Of these 16 chemicals, seven were deemed to contain chemicals of a

potentially ‘hazardous’ nature. These fluids were characterised further to understand the

consequence of the release of the chemical into the environment. Of these seven, four were solid

and insoluble and were removed from further characterisation as there is little to no risk that

these drilling ‘fluids’ will move off site to affect MNES.

Further characterisation was undertaken on the drilling fluids Nuosept 78, Aldacide G, Idcide-20

and caustic soda. These chemicals are mainly biocides, most are readily biodegradable, and do not

bioaccumulate. They are identified as being potentially harmful to very toxic to fish, invertebrates

and algae. These chemicals were assessed as having a potentially high magnitude of impact to

ecosystems should they be directly released to surface water.

MNES present in the WSGP Project Area, and potential contaminant receptors, include nationally

threatened species and ecological communities such as Brigalow and semi-evergreen vine thickets

(SEVT), Curlew Sandpiper and Australian painted snipe; and water resources including Great

Artesian Basin aquifers such as the Gubberamunda Sandstone and their groundwater users,

ephemeral surface water systems and groundwater dependent ecosystems.

It was determined that the risk to the MNES receptors from drilling fluids were limited to above

ground chemical spills, the loss of chemicals to aquifers below ground, and the eventual disposal

of the drilling fluids. One-dimensional contaminant transport modelling has been undertaken to

assess the potential contaminant levels at receptors. This modelling concluded that at a receptor

200 m from the CSG well, if a loss of drilling fluid occurred down the bore, after 400 years the

potential contaminant concentration is still lower than the concentrations required to negatively

impact aquatic life (even under the assumptions of conservative mass transport). The modelling

did not incorporate sorption or degradation of the drilling fluid chemicals.

Senex apply several management and mitigation measures to reduce the risk to MNES. These

include drilling protocols such as the Code of Practice for Constructing and Abandoning CSG Wells

and Associated Bores in Queensland (DNRM 2013), and environmental management practices

such as the Environmental Protocol for Field Development and Constraints Analysis (Senex 2016;

Attachment H), an Environmental Management Plan (Senex 2017d; Attachment F) and a Spill

Response Plan (Senex 2017a; Attachment F).

The risk to MNES receptors from drilling fluids was determined both prior to, and following,

mitigation and management measures. The final risk assessment determined that the likelihood

for a drilling fluid to adversely affect an MNES is highly unlikely to unlikely due to the controls in

place during drilling and the protocols in place if a spill did occur. The overall risk to MNES has

been assessed as low significance to insignificant.

1 INTRODUCTION

Klohn Crippen Berger Ltd (KCB) has been commissioned by Environmental Resource Management

Ltd (ERM), on behalf Senex Energy Ltd (Senex), to undertake a chemical risk assessment for

chemicals to be used in coal seam gas extraction as part of the Western Surat Gas Project (WSGP);

a coal seam gas (CSG) project in the Surat Basin region, Queensland.

For this assessment, the Environmental Protection and Biodiversity Conservation Act 1999 (EPBC

Act) (Commonwealth of Australia 2016) is the central piece of environmental legislation at the

Commonwealth level. It provides for the protection of environmental values, including Matters of

National Environmental Significance (MNES). Actions that are likely to have a significant impact on

MNES are subject to the assessment and approval process under this Act. For this project the

MNES are identified as water resources, wetlands of international importance, nationally

threatened species and ecological communities, and migratory species.

Under the EPBC Act, Senex have been requested to prepare a Public Environment Report (PER).

Section 6 of the guidelines, provided by the Department of Environment and Energy (DoEE),

associated with the PER state the following:

a) The PER must provide a chemical risk assessment of the chemicals to be used in coal seam

gas extraction in accordance with best practice national or international standards and

guidelines.

b) The PER must include a complete list of chemicals to be used in coal seam gas extraction

for the project, which must include chemical name; CAS registry number; likely quantities;

concentrations; and the chemical’s general purpose and function.

c) consideration of the chemical life-cycle under specific site conditions both at the surface

and subsurface;

d) mitigation and management measures to reduce the risk to MNES to a low level for each

listed chemical;

e) a monitoring and reporting framework to assess the efficacy of the proposed mitigation

and management measures;

f) a schedule for the regular review of the listed chemicals, including the inclusion of new

chemicals; and

g) a peer review by a suitably qualified chemical risk assessment expert/s, including a

statement that they carried out the peer review of the findings of the chemical risk

assessment and evaluated the adequacy of the proposed monitoring, mitigation and

management measures.

This assessment has been prepared to address the requirements of Section 6 of the PER. The

chemicals proposed to be used in CSG extraction for development of the WSGP, during production

and development activities, will be introduced through the use of drilling fluids during

completions, workovers and abandonment of wells, and the subsequent disposal only. Hydraulic

fracturing is not proposed to be used. This assessment will assess the risk to MNES through the

chemicals used in drilling fluids.

This report was submitted to the DoEE in December, 2017 and has subsequently been revised to

incorporate feedback received on January 12, 2018.

1.1 Project Overview

Senex (ACN 008 942827), on behalf of its wholly-owned subsidiary Stuart Petroleum Cooper Basin

Gas Pty Ltd, is proposing to produce and supply raw or treated gas to domestic markets and

neighbouring operators (third parties) and distribute gas via existing pipelines and LNG processing

facilities through its WSGP.

The Production Area within the WSGP covers an area of ~686 km2 and is located approximately

30 km northeast of Roma, in Queensland’s Surat Basin. The location of the WSGP is presented in

Figure 1-1. Gas field production activities are planned to commence in 2018, subject to approvals,

and will include the following activities:

� Drilling, installation, operation and maintenance of up to 425 CSG production wells

(vertical), targeting the Walloon Coal Measures (WCM) of the Surat Basin, over an

estimated 47-year project life;

� Installation, operation and maintenance of gas and water gathering flowlines;

� Installation, operation and maintenance of associated supporting infrastructure

(e.g. temporary workforce accommodation, access roads, power and communication

systems, laydowns, stockpiles and storage areas);

� Decommissioning and rehabilitation of infrastructure and disturbed areas;

� Installation, operation and maintenance of compressor facilities and medium pressure

infield pipelines.

� Installation, operation and maintenance of water storage and water management

facilities.

This assessment is related to use of drilling fluids only, which occurs during initial drilling,

maintenance and decommissioning. Further information on the drilling of CSG production wells

are provided in Section 3.1.

2 ASSESSMENT OF SIGNIFICANT IMPACT

This report has been prepared with consideration to key policies and legislation from the

Commonwealth of Australia. This section provides an overview of key legislation / policies

relevant to this assessment.

2.1 Environmental Protection and Biodiversity Conservation Act 1999

The Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act) (Commonwealth

of Australia 2016) is the central piece of environmental legislation at the Commonwealth level. It

provides for the protection of environmental values, including matters of national environmental

significance (MNES). Actions that are likely to have a significant impact on MNES are subject to the

assessment and approval process under this Act. Water resources in relation to large coal mining

and CSG development projects are a MNES. This project was referred to DoEE and determined to

be a controlled action (with water resources being a controlling provision) to be assessed by

Public Environment Report (PER).

Significant Impact Guidelines 1.3: Coal Seam Gas and Large Coal Mining Developments

The ‘Significant impact guidelines 1.3: Coal seam gas and large coal mining developments –

impacts on water resources’ (DoEE 2013c) identify a ‘significant impact’ as ‘an impact which is

important, notable, or of consequence, having regard to its context or intensity’.

Section 5.2 and 5.3 of the guidelines, identify that for a water resource a ‘significant impact’ may

occur where, as a result of the action, one of the following changes to the hydrological

characteristics of a water resource are of a sufficient scale or intensity to significantly reduce the

current or future utility of the water resource for third party users, including environmental and

other public benefit outcomes:

a. changes in the water quantity, including the timing of variations in water quantity;

b. changes in the integrity of hydrological or hydrogeological connections, including

substantial structural damage (e.g. large scale subsidence); and

c. changes in the area or extent of a water resource.

DoEE have identified the following aspects that may need to be considered when assessing the

above hydrological characteristics:

� flow regimes (volume, timing, duration and frequency of surface water flows);

� recharge rates to groundwater;

� aquifer pressure or pressure relationships between aquifers;

� groundwater table and potentiometric surface levels;

� groundwater-surface water interactions;

� river-floodplain connectivity;

� inter-aquifer connectivity; and

ERM





Page 6


� coastal processes including changes to sediment movement or accretion, water circulation

patterns, permanent alterations in tidal patterns, or substantial changes to water flows or

water quality in estuaries.

The Significant impact guidelines 1.3, section 5.4, provide guidance on changes to water quality

stating that a significant impact on a water resource may occur where, as a result of the action:

� there is a risk that the ability to achieve relevant local or regional water quality objectives

would be materially compromised, and as a result the action:

� creates risks to human or animal health or to the condition of the natural environment

as a result of the change in water quality;

� substantially reduces the amount of water available for human consumptive uses or

for other uses, including environmental uses, which are dependent on water of the

appropriate quality;

� causes persistent organic chemicals, heavy metals, salt or other potentially harmful

substances to accumulate in the environment;

� seriously affects the habitat or lifecycle of a native species dependent on a water

resource; or,

� causes the establishment of an invasive species (or the spread of an existing invasive

species) that is harmful to the ecosystem function of the water resource; or

� there is a significant worsening of local water quality (where current local water quality is

superior to local or regional water quality objectives); or,

� high quality water is released into an ecosystem which is adapted to a lower quality of

water.

Changes to water quality as a result of the use of drilling fluids have been assessed as part of this

assessment for the identification of potential impacts.

For purposes of this assessment a water resource is defined as:

“being surface or groundwater, or a watercourse, lake, wetland (whether or not it

currently has water in it) or aquifer and including all aspects of the water resources

including water, organisms and other components and ecosystems that contribute to the

physical state and environmental value of the water resource” (Commonwealth of

Australia 2007).

Matters of National Significance: Significant Impact Guidelines 1.1

The Significant impact guidelines 1.1 (DoEE 2013a) identify a ‘significant impact’ as an “impact

which is important, notable, or of consequence, having regard to its context or intensity”. A

‘significant impact’ on a critically endangered and endangered species, may occur where, as a

result of the action, there is a real chance or possibility that it will:

� lead to a long-term decrease in the size of a population;

� reduce the area of occupancy of the species;

� fragment an existing population into two or more populations;

ERM





Page 7


� adversely affect habitat critical to the survival of a species;

� disrupt the breeding cycle of a population;

� modify, destroy, remove, isolate or decrease the availability or quality of habitat to the

extent that the species is likely to decline;

� result in invasive species that are harmful to a critically endangered or endangered species

becoming established in the endangered or critically endangered species’ habitat;

� introduce disease that may cause the species to decline; or,

� interfere with the recovery of the species.

For ecological communities, a ‘significant impact’ may occur, where, as a result of the action,

there is a real chance or possibility that it will:

� reduce the extent of an ecological community;

� fragment or increase fragmentation of an ecological community, for example by clearing

vegetation for roads or transmission lines;

� adversely affect habitat critical to the survival of an ecological community;

� modify or destroy abiotic (non-living) factors (such as water, nutrients, or soil) necessary

for an ecological community’s survival, including reduction of groundwater levels, or

substantial alteration of surface water drainage patterns;

� cause a substantial change in the species composition of an occurrence of an ecological

community, including causing a decline or loss of functionally important species, for

example through regular burning or flora or fauna harvesting;

� cause a substantial reduction in the quality or integrity of an occurrence of an ecological

community, including, but not limited to:

� assisting invasive species, that are harmful to the listed ecological community, to

become established, or

� causing regular mobilisation of fertilisers, herbicides or other chemicals or pollutants

into the ecological community which kill or inhibit the growth of species in the

ecological community, or

� interfere with the recovery of an ecological community.

For an action to have a significant impact on a migratory species there must be a real chance or

possibility that it will:

� substantially modify (including fragmenting, altering fire regimes, altering nutrient cycles

or altering hydrological cycles), destroy or isolate an area of important habitat for a

migratory species;

� result in an invasive species that is harmful to the migratory species becoming establish in

an area of important habitat for the migratory species, or

� seriously disrupt the lifecycle (breeding, feeding, migration or resting behaviour) of an

ecologically significant proportion of the population of a migratory species.

2.2 Risk Assessment Methodology

2.2.1 Methodology Overview

A risk assessment was undertaken in four stages as shown in Figure 2-1, adopting the guidance

provided in the Organisation for Economic Co-operation and Development (OECD) Risk

Assessment Toolkit (OECD 2014) as per the requirements for the chemical risk assessment under

Section 6 of the PER. The toolkit identifies that an environmental risk assessment should involve:

1. Hazard identification

2. Hazard characterisation

3. Exposure assessment

4. Risk characterisation.

This approach is generally consistent with AS/NZS 4360:2004: Risk Management and AS/NZS ISO

31000:2009 Risk Management – Principals and Guidelines (AS/NZS 2004, 2009). This assessment is

a qualitative evaluation of risk; a risk matrix approach was adopted in the risk characterisation

process. The Environmental Risk Assessment of Chemicals used in WA Petroleum Activities

Guideline was also referred to whilst there is no definitive guideline available in Queensland

(Department of Mines and Petroleum 2013).

Figure 2-1: Chemical Risk Assessment Process Schematic (Based on OECD Toolbox; OECD 2014)

HAZARD IDENTIFICATION

Identify types of chemicals and volumes to be used. Review information related to

chemical properties.

HAZARD CHARACTERISATION

Consider the chemical properties and volumes in the context of the environment and

MNES and potential receptors.

EXPOSURE ASSESSMENT

Identify if an exposure pathway exists from the proposed activities and use of chemicals

with consideration to the hazard characterisation.

RISK CHARACTERISATION

Provide context of the risk associated with using the chemical for the proposed activity.

Provide mitigation measures and the associated mitigated risk.

In assessing the environmental impact from drilling fluid chemicals, the following stages of the

chemical lifecycle were considered:

� Transport and storage to and on the drilling site;

� Processing on site at the CSG production well head prior to use;

� During use down hole; and,

� Disposal of the fluid.

2.2.2 Hazard Identification

Hazard identification involved identifying products and chemicals to be used during the drilling

process. It details how the products will be used and assesses the hazardous nature of the

products and the chemicals within them.

A product or chemical is considered to be a hazard (Department of Mines and Petroleum 2013) if:

� it meets health hazard criteria (acute toxicity or chronic toxicity to human health through

the use of affected water resources);

� It meets environmental health hazard criteria (acute aquatic toxicity, chronic aquatic

toxicity, bioaccumulation or persistence); and / or,

� It has been identified as a pollutant, contaminant or hazardous good on the Safety Data

Sheet (e.g. as determined by Safe Work Australia and / or 3rd Revised Edition of the

Globally Harmonised System of Classification and Labelling of Chemicals (GHS)).

Any products or the chemicals within them, identified as hazardous were assessed further under

this risk assessment methodology. The risk assessment considered only harm to MNES, and did

not consider human health on site during the drilling (these are outlined in the safety data

sheets).

Products and Chemicals Not Requiring a Detailed Risk Assessment

Products or chemicals not deemed to require a detailed risk assessment in the context of this

assessment included:

� Products comprised of natural ingredients;

� Product that are an inert, man-made substance; and / or,

� Products that did not meet the criteria of being harmful, toxic or very toxic to human

health and / or the environment; were not classed as a known carcinogen, mutagen or

toxicant to reproduction, fertility or development; and do not meet criteria for being

persistent or bioaccumulative.

2.2.3 Hazard Characterisation

Where a drilling fluid was deemed to be potentially hazardous according to the criteria above,

further hazard characterisation was undertaken. This characterisation further assessed the drilling

fluids and their chemical constituents to consider:

ERM





Page 10


� The nature and state of the chemicals at surface and their solubility, to determine the

potential for chemical to enter the environment;

� The fate and transport of the chemical in the environment including an assessment of the

mobility, potential for bioaccumulation and degradation; and,

� An assessment of the volumes of chemicals proposed to be used in the context of the

environment, with a comparison against relevant environmental hazard criteria.

The fate of a chemical depended on its chemical and physical properties including its persistence,

solubility, binding ability, volatility and how it reacts with the environment that it is released into.

Relevant information on the chemicals was obtained from the following sources:

� Safety Data Sheets (SDS) provided by the companies for the products proposed to be used

in the drilling activities (Appendix II);

� OECD ‘Global Portal to Information on Chemical Substances’ (or eChemPortal) (OECD

2015); and

� The TOXNET Hazardous Substances Data Bank (HSDB), accessed July 2017 (NIH 2017).

2.2.4 Exposure Assessment

Exposure assessment identified the potential chemical sources and the ‘risk events’ which may

result in their release to the environment, and consideration of the likely fate and transport of the

chemical, the likely exposure pathways and resulting impacts on MNES.

The potential transport of these chemicals to MNES receptors has been considered using one

dimensional (1D) analytical contaminant transport modelling which assesses the time to receptor

and subsequent potential contaminant concentration. This provides the potential exposure at the

receptor if a spill occurred and no mitigation or management measures were in place.

Exposure Pathways

Exposure pathways can include:

� Ingestion of chemicals though drinking water; and,

� Skin contact with chemicals in relation to contaminated water.

A comprehensive list of potential chemical sources and risk events are identified and their

subsequent potential MNES receptors.

Groundwater Transport Modelling

An analytical 1D contaminant transport model, using industry accepted contaminant transport

equations, was used to determine what concentration of drilling chemicals could reach any MNES

receptors an arbitrary distance away, and how long would it take to reach this concentration.

The model uses analytical equations based on the characteristics of the aquifer, the potential

hydraulic gradient within that aquifer and the distance to the receptor. The adopted model uses

the Domenico equation (Domenico 1987) which has been modified with the addition of stochastic

modelling approaches to provide a range of results, based on the available data:

ERM





Page 11


Where:

CED = concentration of contaminant at point x and time t (mg/l)

Co = initial contaminant concentration in groundwater (mg/l)

λ = decay constant

ax, ay, az = longitudinal, vertical and lateral dispersivity (m)

Sz, Sy = width and thickness of plume at source (in saturated zone) (m)

u = rate of contaminant movement due to retardation, where:

� =��

��

Rf = retardation factor

n = effective porosity

i = hydraulic gradient

K = hydraulic conductivity (m/d)

x = distance to compliance point (m)

erfc = complimentary error function

erf = error function

exp = exponential

t = time since contaminant entered groundwater (days)

The Domenico analytical equation is adopted for this assessment due to its versatility and

widespread use in many attenuation assessment tools (Aziz, Newell, Gonzales, Hass, Clement and

Sun 2000), and the incorporation of degradation and retardation factors in the calculation.

Model Assumptions

The Domenico Analytical Equation assumes:

1. Fixed dimensions of a contaminant source

2. Homogenous aquifer properties

3. One dimensional groundwater flow

4. First order degradation rate (where degradation is considered)

5. Contaminant concentration estimated at the centreline of the plume

ERM





Page 12


6. Molecular diffusion based on concentration gradient is neglected

No retardation (e.g. sorption) in the transport process for the assessment of conservative

contaminants (a retardation factor of 1 is applied). Where retardation is applied in the retardation

simulation, there is an assumption that there are unlimited surfaces for sorption to occur.

2.2.5 Risk Characterisation

Risk characterisation involved the potential for (likelihood) and the magnitude (significance) of the

risk to MNES from drilling fluids.

2.3 Identification of Management and Mitigation Measures

All measures applied by Senex to manage and mitigate the risk to the environment from drilling

fluids are described. These measures are designed to reduce the likelihood and subsequent risk to

MNES as identified in the exposure assessment.

2.4 Assessment of Risk

The risk assessment considered the likelihood of exposure and a rating of the consequence of the

exposure.

The likelihood of exposure was assessed by examining the likelihood that the chemical could

reach the receptor based on known pathways and following the application of the management

and mitigation measures (Table 2-1).

Table 2-1: Likelihood of Exposure Assessment

Rank Descriptor Likelihood of Exposure

1 Highly unlikely There is no known connection between the source and receptor – there is no pathway

i.e. source is solid and not soluble – highly unlikely pathway to surface water system.

2 Unlikely Unlikely connection between the source and the receiving environment.

Unlikely for a surface spill to reach the receiving environment.

3 Possible

Possible connection between the source and the receptor (i.e. connection of coal seams

with an aquifer being used for extraction). Possible that surface spills could reach the

receiving environment.

4 Likely Likely connection between the source and the receiving environment. Likely that spills

could reach receiving environment.

5 Very likely

Confirmed connection between the source and the receiving environment, with the

receiving environment (aquifer) being used for drinking water or discharging to an

ecosystem. Very likely that a surface spill will reach receiving environment.

The consequence of each drilling fluid chemical was then assessed using the consequence levels in

Table 2-2. The consequence of a chemical to MNES is based on the hazard characterisation of

each chemical.

Impacts are at a regional, national or international scale.

Impacts to groundwater may include impacts across aquifers regionally.

Groundwater discharge features and users are affected.

A final risk rating was determined for each particular risk by combining the consequence level

with the likelihood level. This is outlined in Table 2-3. The risk rating adopted is specific to this

assessment and is consistent with AS/NZS 4360:2004: Risk Management and AS/NZS ISO

31000:2009 Risk Management – Principals and Guidelines (AS/NZS 2009, 2004).

The risk to water resources MNES from drilling fluids was considered using the EPBC Significant

impact guidelines 1.3 (DoEE 2013c), where a ‘significant impact’ is described as an impact which is

important, notable or of consequence, having regard to its context or intensity.

A significant impact is likely when (DoEE 2013b):

“To be likely, it is not necessary for a significant impact to have a greater than 50% chance

of happening; it is sufficient if a significant impact on the environment is real or not remote

chance or possibility”.

The subsequent risk rating was determined with regards to the significant impact guidelines and

MNES:

� High significance: Significant impact with high likelihood of impact to MNES. Levels of

chemical risks are regarded as unacceptable or intolerable. Impact results may be

ERM





Page 14


irreversible or persistent high severity impact on the quality or availability of surface or

groundwater;

� Moderate significance: Levels of chemical risks are regarded as unacceptable, moderate

severity with impacts persisting over time. Impacts may be tolerable but risk treatment

and mitigation should apply where possible;

� Low significance: The MNES will be affected by low severity impact. Impacts are of short

duration and the receptor will have a rapid recovery when the activity is complete; and

� Insignificant: An insignificant impact exists to an environmental value. Levels of chemical

risks are regarded as acceptable and no risk treatment is necessary. The impact is of low

severity and restricted to the immediate area of activity. There are no medium or long-

term impacts and recovery is rapid.

3 DESCRIPTION OF PROPOSED ACTION

3.1 Project Location

The WSGP is located approximately 30 km north of the Warrego Highway, between the townships

of Roma and Wallumbilla. The location of the WSGP is presented in Figure 1-1.

The area of the proposed action known as the WSGP Production Area covers an area of

approximately 686 km2 and comprises ATP767, ATP795, and ATP889, which consists of nine

individual development blocks (Glenora, Eos, Mimas, Tethys, Phoebe, Pandora, Rhea, Dione and

Titan), as shown on Figure 1-1. The CSG production target for the WSGP is the Walloon Coal

Measures (WCM). Development CSG activities will be undertaken in the WSGP Production Area,

which is referred to as WSGP for the remainder of this report.

3.2 Project Status

A summary of the WSGP’s approval status within the legislative / regulatory framework is

provided in the following:

� Senex is currently authorised to conduct petroleum exploration activities in accordance

with its Environmental Authority (EA) EPPG00651513, within petroleum tenures ATP 767,

795 and 889 under the Environmental Protection Act 1994 (State of Queensland 2016a).

The existing EA already includes conditions authorising well construction and maintenance

that are not proposed to be amended.

� Applications for Petroleum Lease (PL) 1022, 1023 and 1024, under the Petroleum and Gas

(Production and Safety) Act 2004 (State of Queensland 2017a), were made to the

Queensland Department of Natural Resources and Mines (DNRM) in December, 2016.

� Given that an EA must be in place prior to the granting of PLs, Senex have applied to the

DEHP for an amendment of its EA (EPPG00651513) to authorise production activities.

Senex submitted their amendment application and supporting information to DEHP in

June, 2017 and a decision is pending.

� The proposal was referred to the then Department of Environment for consideration

under the Environment Protection and Biodiversity Conservation Act 1999. The proposal

was determined to be a controlled action in May 2015.

� The proponent sought to vary the Referral as a result of a reduced project scope and area,

which was granted by the Department of the Environment and Energy (DoEE) in March

2017.

� The DoEE have determined that the proposed action (WSGP) will be assessed by Public

Environment Report (PER) under the EPBC Act. This chemical risk assessment of drilling

fluids forms part of the PER (Section 6).

3.3 Drilling Activities

3.3.1 Activity Description

The WSGP will involve drilling and completing approximately 425 CSG production wells over the

estimated 47-year project life. A description of the activities associated with the drilling can be

(expected to be

CSG production wells will optimally be set out with a target of 1250 m grid spacing. This could

range between 700 m and 1,500 m. Some locations may not be drilled depending on land access,

cultural heritage and environmental constraints. This spacing would provide for approximately

~50 wells per development block (Figure 3-1). The actual number of CSG production wells to be

developed within any given block will be determined based on a detailed assessment of all

environmental, cultural heritage and land access constraints within that block (Attachment H -

Senex 2016). Further discussion on determining the locations of the CSG production wells is

provided in Section 3.3.4.

The operating life of a CSG production well is expected to be approximately 25 to 30 years. Senex

expects that peak drilling will be in the order of 30 to 50 CSG production wells per annum. Once

depleted, CSG production wells will be plugged, abandoned and rehabilitated, with new CSG

production wells drilled to maintain production needs. The anticipated future production scenario

or field development sequencing is presented in Figure 3-1, which is based on the June 2016

future plan1.

1 Note that field development planning may change as new information becomes available during the life of the Project.

Figure 3-1: Proposed WSGP Future Production Scenario (June 2016 Future Plan)

3.3.2 Code of Practice for Constructing and Abandoning Coal Seam Gas Wells and Associated

Bores in Queensland

All CSG production wells will be designed, constructed and decommissioned in accordance with

the “Code of Practice for constructing and abandoning coal seam gas wells and associated bores in

Queensland” (DNRM 2013). This code outlines mandatory requirements and good practice to

reduce the risk of environmental harm. Senex will follow this code of practice as a minimum

requirement for the CSG well construction and management of the WSGP wells.

CSG production wells will be designed to:

� Prevent any interconnection between hydrocarbon bearing formations and aquifers

� Ensure that gas is contained within the well and associated pipework and equipment

without leakage

� Ensure zonal isolation between different aquifers is achieved

� Not introduce substances that may cause unlawful environmental harm.

With relation to drilling fluids, the mandatory requirements include:

� Drilling fluids must be selected and managed to ensure all manufactured products used

during well procedures on CSG wells are in accordance with the manufacturer’s

recommendations and relevant SDS

ERM





Page 18


� The name, type and quantity of each chemical used on each well throughout the life of the

well must be recorded.

Good industry practice includes:

� Drilling fluid should be a carefully monitored and controlled mixture designed to:

� Achieve best drilling results and ensure efficient removal of formation cuttings

� Control formation pressures

� Minimise damage to formations

� Petroleum tenure holders should ensure that the drilling fluid selected is appropriate for

the well design to manage any locally experienced drilling problems and the geological

conditions likely to be encountered.

� The use of biodegradable substances in the drilling fluid is preferred.

� The source of water for all well procedures (drilling, completion, workover and

abandonment) should be recorded for future well monitoring purposes.

� Products should be chosen, stored, and used at concentrations that minimise the risk of

causing environmental harm.

� Personnel, including contractors, should be aware of the environmental impact and

emergency spill procedures for the products and substances in use on site.

� Petroleum tenure holders should use established, effective drilling practices to achieve a

stable, uniform and, as far as possible, in-gauge hole.

Hydraulic fracture stimulation will not be undertaken as part of the WSGP.

3.3.3 Using Drilling Fluids

While drilling, fluid will be circulated down the drill string and up the annulus (space) between the

drill string and well wall. Drilling fluids serve to lubricate the drilling assembly, remove the

formation cuttings, maintain control of the well and stabilise the hole being drilled.

Drilling fluid, or muds, generally consist of a mixture of water, clays, fluid loss control additives,

density control additives, and viscosifiers. Oil-based and synthetic oil-based drilling muds will not

be used.

To avoid well formation damage and to limit corrosion, a drilling fluid specific for each CSG

production well will be selected that is appropriate to the well design, and local experience and

anticipated geological conditions. The standard drilling fluid used by Senex is water-based.

Potassium chloride or similar, may be used as a weighting agent to help control swelling clays.

Organic polymers and clays may be added to the base fluid to raise the viscosity and assist in

removing drill cuttings. Compounds that include benzene, toluene, ethylbenzene, or xylenes,

(known as BTEX) will not be used. Biocides may be used during drilling and workover of

production wells to prevent microbial growth and contamination and prevent the buildup of

biofilms.

ERM





Page 19


Drilling fluids are selected and managed to ensure all products are used in accordance with the

manufacturer’s recommendations and relevant SDS. The name, type and quantity of each drilling

fluid additive used on each well is recorded.

Information on drilling fluids is also required to be included in the ‘well completion report’ for

each well. This is required to be submitted to the DNRM under the Petroleum and Gas (Production

and Safety) Regulation 2004 (State of Queensland 2017b).

Existing Use of Drilling Fluids

Drilling fluids have been used during the drilling of exploratory and pilot wells. To date there has

been no loss of drilling fluids.

3.3.4 Drilling Locations

To support CSG field layout for all infrastructure, including wells and gathering pipelines, Senex

will implement their ‘Environmental Protocol for Field Development and Constraints Analysis’

(Senex 2016; Attachment H) (the Constraints Protocol) for all cases where construction will

involve significant disturbance to land. The Constraints Protocol aims to limit impacts such that

infrastructure siting:

� Considers biodiversity values and environmental constraints, such as sensitive receptors,

when selecting preferential locations; and aligning with planning principles to avoid,

minimise, mitigate and then manage potential environmental impacts;

� Is compliant with EA conditions and State and Federal regulatory requirements; and

� Identifies any additional external environmental approvals required and that those are

secured prior to the commencement of construction activities.

With respect to environmental values, the protocol addresses avoiding or minimising and

managing potential impacts to:

� Biodiversity values contributing to MNES

� Habitat for wildlife, including threatened MNES threatened communities, flora and fauna

� Wetlands, watercourses, springs and groundwater dependent ecosystems.

The Constraints Protocol also recognises that, in addition to environmental constraints,

landholder, engineering and cultural heritage constraints must be considered during

infrastructure siting.

The process involves a desktop constraints analysis, site surveys, post-survey environmental

constraints analysis and preparing a report that includes a list of site specific environmental

conditions and associated constraints maps. These are included in the final Access to Work (ATW)

documentation, issued upon sign-off by the WSGP Project Manager to relevant staff and

contractors prior to commencing construction.

ERM

3.4 Waste Materials

The waste materials from the drilling process and their disposal is detailed in Table 3-2. Where

possible drilling fluids will be recycled; and at the end of their lifecycle they will be disposed of at

an appropriately licenced facility.

As per the existing Environmental Authority (EPPG00651513), if sumps are used to store residual

drilling material or drilling fluids, they must only be used for the duration of drilling activities for

that individual well. Residual drilling material can only be disposed of on-site by mix-bury-cover

method if the residual drilling material meets the approved quality criteria (DEHP 2015). The

approved quality criteria requires certification by a suitably qualified third party as being of

acceptable quality for disposal to land by the proposed method and that environmental harm will

not result from the proposed disposal.

Table 3-2: Waste Materials from Drilling and Disposal Options

Waste Material Approximate Quantities Disposal Options

Drill cuttings 10 – 20 m3 per well Left on site or disposed to landfill

Residual muds 75 m3 per well Waste solids to landfill, drill fluids recycled where possible

4 HAZARD IDENTIFICATION AND CHARACTERISATION

This section identified the proposed drilling fluids and their associated chemical make-up, and

assesses the environmental hazard of each through characterisation.

4.1 Use of Drilling Fluids

Drilling fluids containing chemicals, may be utilised during the following activities:

� The drilling of exploration and appraisal wells / core holes (some of these bores will

subsequently be converted to CSG production wells);

� The drilling of CSG production wells;

� Completion and workover of the CSG production wells on a three to five-year frequency;

and,

� On abandonment of the CSG production wells. This is not expected to occur until at least

15 years (or more) after commencing producing CSG from a well.

4.2 Proposed Drilling Fluids

The proposed drilling fluids and when they are planned to be used are detailed in Table 4-1 to

Table 4-4. A total of 16 different drilling fluids that may be used have been assessed. The tables

provide the following:

4.2.1 Potentially Hazardous Chemicals

An initial review of each of the drilling fluids and their contents was undertaken to assess whether

further characterisation and risk assessment was required. This assessment is summarised in

Table 4-5.

As detailed in Section 2.2, a product or chemical is considered hazardous based on its health

hazard criteria, environmental hazard criteria and whether it has been identified as a pollutant,

contaminant or hazardous good under Australian legislation or regulations.

Seven chemicals were deemed to be ‘hazardous’ through their SDS and were identified as

requiring further characterisation. These are:

� Nuosept 78

� Safe-Carb 250

� Aldacide G

� Idcide-20

� Caustic Soda

� Baracarb 1200

� Stoppit.

4.3 Hazard Characterisation

The seven drilling fluids identified for further assessment in Section 4.2.1 were further

characterised in the sections below.

4.3.1 Chemical Nature

The nature and state of the chemicals at surface and their solubility was assessed to determine

the potential for the chemical to enter the environment. Where a chemical is a solid at surface

and is insoluble in water, it is assumed that the chemical is unlikely to mobilised away from the

drill pad, and if present down a well is unlikely to mobilise through an aquifer. It is assumed that

there is little to no risk that the chemical will migrate off site and these chemicals are not

considered to present a risk to MNES, further hazard characterisation was not required. Three of

these drilling chemicals are solid and insoluble and present little to no risk to the water

environment, these will not be assessed further (Table 4-6).

environment. The chemical fate and transport informed the potential consequence of a release of

the chemical into the environment. The following four chemicals were considered further:

� Nuosept 78;

� Aldacide G;

� Idcide -20; and,

� Caustic soda.

Mobility, potential for bioaccumulation and their degradation was assessed and is summarised in

Table 4-7 below. These chemicals are mainly biocides; most are readily biodegradable, and do not

bioaccumulate.

Narran Lakes Nature Reserve has been identified as a controlling provision under the EPBC

referral for the WSGP (Table 5-2).

Table 5-2: Wetlands of International Importance in Proximity to the WSGP (ERM 2017)

Wetland of International

Importance (Ramsar) Proximity Comment

Narran Lake Nature

Reserve

400 km

downstream

Located in northern central NSW downstream of the Production

Area. This feature is discussed in further detail below.

The Narran Lake Nature Reserve Ramsar Site (‘the Ramsar site’) is approximately 400 km from the

Production Area, within New South Wales. It is located on the terminal wetland system of the

Narran River, a distributary of the Balonne River in the Condamine-Balonne catchment of the

Murray Darling Basin (Butcher and Hale 2011).

Both the Production Area and the Ramsar site are located within the Condamine-Balonne

catchment. The Production Area is approximately 400km upstream of the Ramsar site, and as such

there is a hydrological link to this wetland of international importance.

The Ramsar site is comprised of extensive channelised floodplain and floodplain lakes. The

geomorphic setting provides a diverse range of wetland areas. Surface inflows are the dominant

source of water for the site with groundwater-surface water interactions believed to be negligible.

Butcher and Hale (2011)report that flows are generated in the headwaters of the catchment

rather than from downstream of Narran River confluence. The proposed WSGP is unlikely to

impact the Ramsar site given the distance from the Production Area, the fact that Wells will be

drilled, constructed and abandoned in accordance with all relevant legislative requirements of

Petroleum Legislation, the Code of Practice for constructing and abandoning Coal Seam Gas wells

and associated bores in Queensland (Department of Natural Resources and Mines, 2013) and that

ERM





Page 32


there will be no discharge of water to the surface waterways as a result of production activities

and that erosion and sediment controls will be implemented in accordance with the

Environmental Management Plan (EMP).

5.2 Nationally Threatened Species and Ecological Communities

5.2.1 Ecological Communities

Three threatened ecological communities (TEC) have potential to be present within the WSGP and

are summarised in Table 5-3 (Senex 2017b). A summary of the TECs and the reliance on

groundwater is provided in Table 5-3. While all flora and fauna are reliant on a water source to

some extent, the assessment has focussed on identifying species or communities with a strong

association with groundwater sources or surface water bodies (rather than rainfall runoff flows).

5.2.2 Threatened and Migratory Species

The EPBC Act threatened and migratory species that are possible to occur or have been confirmed

as being present in the WSGP are summarised in Table 5-4. Their habits and general dependence

(other than water for drinking) is noted.

5.3 Water Resources

Information related to water resources within the vicinity of the WSGP has been sourced from the

Water Resources Assessment Report (KCB 2017) prepared for the Independent Expert Scientific

Committee on Coal Seam Gas and Large Coal Mining Projects (IESC).

5.3.1 Surface Water

The WSGP is located across multiple river basins and sub-catchments. The northern extents of the

WSGP area occurs within the Upper Dawson River sub-basin (within the wider Fitzroy River Basin),

while the central and lower extents occur within the Upper Balonne River sub-basin (within the

wider Condamine-Balonne River Basin).

Major sub-catchments within the vicinity of the WSGP as well as the associated major and minor

drainages are presented in Figure 5-1. These include:

� Upper Dawson River Sub-Basin (Fitzroy River Basin):

� Eurombah Creek sub-catchment;

� Upper Balonne River Tributaries Sub-Basin (Condamine-Balonne River Basin):

� Bungeworgorai Creek sub-catchment;

� Bungil Creek sub-catchment;

� Balonne River sub-catchment; and

� Yuleba Creek sub-catchment.

The hydrology of the WSGP area is directly influenced by the distinct seasonal rainfall and the

associated, highly variable, streamflow patterns. These watercourses can also experience periodic,

high energy flood events that may cause rapid adjustments to channel morphology. Land use in

the WSGP area has also greatly increased the vulnerability of stream banks to erosion during high

energy floods, which result in downstream movement of large volumes of sediment (Senex

2017b).

Surface Water Dependent Ecosystems and Species

Due to the ephemeral nature of the watercourses, there are limited aquatic ecosystems in the

watercourses. The watercourses provide drainage paths and intermittent habitat for aquatic

species.

Field surveys revealed very few observations of aquatic flora and fauna, and confirmed the overall

paucity of permanent water. Those survey sites where water was present were found to be

significantly impacted by grazing, vegetation clearing and erosion in some locations. Instream

habitat for aquatic species present in the Production Area was generally uniform and highly

dependent on the presence of bars, and woody debris (Senex 2017b). Pools were rarely observed,

and where present were shallow and limited in size (a few metres) suggesting they do not provide

significant refuge for biota. Grasses and other vegetation were commonly reported within first

order stream beds suggesting less than annual occurrence of significant scouring flow (Senex

2017b). There is potential these water courses provide limited values for aquatic biota, especially

given the overall paucity of permanent water courses within the Production Area.

Third-Party Surface Water Users

The surface water resource of the Upper Dawson sub-basin is managed under the Queensland

Water Resource Plan framework as part of the Water Plan (Fitzroy Basin) 2011 (State of

Queensland 2016c). The Fitzroy Basin Resource Operations Plan (ROP) (DNRM 2015) provides the

process to implement the Water Plan (Fitzroy Basin) 2011 (State of Queensland 2016c). Under the

Fitzroy Basin ROP (DNRM 2015), Eurombah Creek occurs within the Dawson Valley Water

Management Area. Within this management area Eurombah Creek is a tributary of the Dawson O

Zone, along the AMTD reach 428.0-453.5 (km); and, is described as ‘Eurombah Creek Junction to

Utopia Downs Gauging Station’. There are no resource operations licence holders in the Dawson O

Zone of the Dawson Valley Water Management Area.

The surface water resource of the Maranoa-Balonne Sub-Basin is managed under the Queensland

Water Resource Plan framework as part of the Water Plan (Condamine and Balonne) 2004 (State

of Queensland 2016b). The Condamine-Balonne Resource Operations Plan (ROP) (DNRM 2015)

provides the process to implement the Water Plan (Condamine-Balonne) 2004. This plan was

approved in December 2008 and amended in July 2015. The WSGP area falls within the

Condamine and Balonne Tributaries Water Management Area. No surface water users have been

identified within the vicinity of the WSGP.

5.3.2 Groundwater

Regional Overview

The WSGP is located within the geographical extent of the Surat Basin, a basin of Jurassic-

Cretaceous age, which is underlain by the Permo-Triassic Bowen Basin. Cenozoic-age formations

are present overlying the Surat Basin formations. The surface geological map within the vicinity of

the WSGP is shown in Figure 5-2.

Local Hydrogeology

The Walloon Coal Measures (WCM) is the target formation for gas production for the WSGP,

which is part of the Surat Basin.

The Surat Basin forms part of the Great Artesian Basin (GAB), which is comprised of several

aquifers and confining aquitards. Aquifers of the Surat Basin are a significant source for water

used for stock, public water and domestic supply. OGIA (2016) presents the hydrostratigraphy of

the Surat and Bowen Basin, included as Figure 5-3. The main aquifers within the GAB, from the

deepest to the shallowest, are the Precipice Sandstone, Hutton Sandstone, Springbok Sandstone,

Gubberamunda Sandstone, Mooga Sandstone and Bungil Formation. These aquifers are typically

laterally continuous, have significant water storage, are permeable and are extensively developed

for water supply. However, in some areas, they have more of the character of aquitards than

aquifers (OGIA 2016). Minor discontinuous aquifers include the Wallumbilla Formation and Orallo

Formation. The major aquitards are the Evergreen Formation, Eurombah Formation, WCM,

Westbourne Formation, Surat Siltstone and Griman Creek Formation (Figure 5-3). Key formations

of the Surat Basin relevant to this assessment are highlighted on Figure 5-3. These formations will

be intersected during the drilling of CSG wells for the WSGP.

Figure 5-4 presents the local basinal hydrostratigraphy sourced from the OGIA Surat CMA UWIR

geological model surfaces (OGIA 2017a). This indicates outcrop areas associated with the WSGP,

include the Springbok Sandstone, Westbourne Formation, Gubberamunda Sandstone, Orallo

Formation, Mooga Sandstone and Bungil Formation. The WCM outcrop is located immediately to

the north of the WSGP. North-south and west-east oriented cross sections are presented in Figure

5-5 with the section locations provided on Figure 5-4. The sections show the units dipping from

outcrop towards the south. Generally, all units are laterally extensive and continuous across the

WSGP area, with the exception of the Precipice Sandstone, which is thin or absent across much of

the area. A key feature present within the WSGP area is the Hutton-Wallumbilla Fault.

Quaternary-age alluvium is mapped as occurring within the vicinity of the WSGP (Figure 5-2).

These alluvial deposits are generally associated with the major creeks, with some mapped

deposits associated with minor tributaries. Field verification was undertaken in March, 2017,

where hydrogeological observations were made in relation to the watercourses and alluvial

deposits within the WSGP area. Watercourses in the WSGP area generally exhibit similar profiles,

with limited incision and alluvial development. The alluvial profile was generally 2-3 m in width,

sometimes wider where associated with meandering channels. Generally, the alluvium observed

comprised medium to coarse grained sand, with occasional gravel, cobbles and sandy clay, likely

derived from erosion of the Gubberamunda Sandstone.

of these potential GDEs are presented in Figure 5-7 and have been categorised by their mapping

rule sets, which correspond to the relevant river basin – Murray Darling, or Dawson River

(Queensland Government 2015b, 2015a). There are three categories (or rulesets) which occur

within the WSGP boundary and considered relevant to this chemical risk assessment. A

description of each is provided in the following:

� eMDB_RS_01 - Alluvia - eMDB: Potential ecosystems dependent on the subsurface

presence of groundwater in alluvial aquifers. Associated with Bungil Creek to the west of

Third-Party Groundwater Users

Groundwater in the Great Artesian Basin is managed within the Water Plan (Great Artesian Basin)

2006 (State of Queensland 2016d), under the Water Act 2000. The WSGP is located within the

Surat (19) and Surat North (20) Management Areas.

Within the WSGP area, there are an estimated 101 existing groundwater bores sourcing water

from the Surat Basin. The location of these bores is presented in Figure 5-8 and are shown by their

attributed aquifer from Senex’s baseline assessment and OGIA’s aquifer attribution dataset (OGIA

2017b). Of these bores, there are an estimated 67 bores that abstract groundwater from the

ERM

formations that will be intersected during drilling of CSG production wells (Mooga Sandstone to

Walloon Coal Measures.

The highest water usage within the WSGP area is attributed to the Gubberamunda Sandstone,

WCM and Hutton Sandstone. Stock and domestic use is the most common groundwater

abstraction purpose, with three bores licenced for agricultural purposes.

6 EXPOSURE ASSESSMENT

An exposure assessment was undertaken that examined the potential risk of using drilling

chemicals This examined exposure pathways included a simplified 1D contaminant transport

model.

6.1 Exposure Pathways

The assessment identified risk events (‘source’), the potential pathways, and the resulting MNES

receptors. This is summarised in Table 6-1.

The main pathways for contaminants are:

� Overland flow – chemicals spilt at the surface, if not contained, may travel via overland

flow into nearby surface water systems. This could result in a reduction of surface water

quality in the local creek systems and may have potential health impacts on dependent

threatened or migratory species if this water is consumed. The surface water systems in

the WSGP are mainly ephemeral systems, the risk of contaminants reaching this system

will be higher during periods of rainfall. Contaminant concentrations at the receptor may

be significantly lower than at the source due to dilution in the surface water system.

� Soaking into the ground – chemicals spilt at surface may soak into the ground. This could

decrease the water quality of the shallow groundwater system and subsequently the

surface water system if there is a connection.

� Groundwater flow – chemicals may be lost from the bore into the WCM reducing the

groundwater quality in this formation. Contaminated groundwater may then flow through

the coal measures and be subsequently extracted from landholder bores or surface at a

groundwater dependent ecosystem or watercourse spring. If a connection between the

WCM and other aquifers exists, either through connections at the CSG well or through

fractures, there may be potential for contaminant migration and subsequent pollution of

these aquifers. Contaminant concentrations at receptors are likely to be much lower than

that at source due to dilution, dispersion, sorption and degradation of the contaminant

prior to reaching the receptor.

� Leaching through the soil – In most cases, drilling mud will be disposed off-site at the end

of their lifecycle. However, in some cases drilling muds will be disposed using mix-bury-

cover methods, if the residual drilling material meets the approved quality criteria. If

disposed of incorrectly, chemicals from the drilling mud may leach from the muds into the

soil. This leachate may enter the groundwater system, moving along groundwater flow

pathways as explained above.

The exposure assessment predicts direct impacts for water MNES. Threatened ecological

communities and ecological species are unlikely to be directly impacted by the use of drilling fluids

during drilling, workover or completions, they could hypothetically be indirectly affected through

drinking contaminated surface water if a spill at surface occurred.

The length of these pathways are currently unknown and have been estimated, as drilling

locations have not been confirmed. To date there have been no known surface spills or losses of

drilling fluids during drilling.

6.2 Groundwater 1D Transport Modelling

As described in Section 2.2.4, contaminant transport modelling was undertaken to assess the

potential concentration of a drilling chemical at a receptor. Surface water spill modelling has not

been undertaken, but the likelihood of a spill is unlikely and can be managed and mitigated more

readily than a groundwater ‘spill’. Senex has standard procedures in place to deal with surface

spills.

6.2.1 Potential Receptors

As there are several potential receptors and the location of the wells has not been confirmed, an

arbitrary groundwater receptor 200 m from a well has been selected for the modelling.

6.2.2 Model Scenarios

Section 5.4 summarised the aquifer formations which supported groundwater abstraction and

were potentially are risk, this included the Walloon Coal Measures, the Springbok Sandstone, the

Gubberamunda Sandstone, the Mooga Sandstone and the Bungil Formation. The model simulated

the movement of a drilling chemical through the most permeable formation, the Gubberamunda

Sandstone. This formation supports groundwater users and GDEs.

6.2.3 Model Parameters

The basic model parameters adopted in the analytical contaminant transport assessment are

6.2.4 Model Sensitivity

Sensitivity in the model was assessed through stochastic simulation of selected parameters. The

following parameters were considered for stochastic consideration of likely parameter bounds:

� Hydraulic conductivity;

� Effective porosity; and

� Hydraulic gradient.

ERM





Page 52


Stochastic modelling follows a Monte Carlo simulation technique which allow multiple realisations

of different "what if" cases where the ranges and distributions of the parameters are assessed.

This allows the range of possible outcomes and their probability of occurring to be assessed.

The Monte Carlo probability capability of GoldSim was used to assign distributions of the input

parameters listed above. The approach allows definition of the assumptions for each input and

the 1-D contaminant transport equations to be assessed for multiple scenarios. This approach

provides a broad understanding of the model variability, with results typically provided as ranges

associated with a probability of occurrence.

6.2.5 Results

In summary:

� The 1D analytical model suggests that in 100 years there will be a concentration of

0.0286 mg/L contaminant concentration at a receptor 200 m from a CSG well. The most

likely concentration is in the range of 1 x 10-3 µg/L with a starting concentration of

572 mg/L which is the chemical concentration of caustic soda before injection (maximum

chemical concentration). See Table 6-3 and Figure 6-1.

� The model was run for 400 years, at this time a maximum concentration at the receptor of

0.35 mg/L is predicted, with the mean (and most likely potential concentration) of

0.07 mg/L.

� These values are lower than the predicted concentrations required to cause an impact on

aquatic life.

� The model does not take into account retardation, degradation or sorption of the chemical

contaminant and concentrations at the receptor, therefore, in reality concentrations are

likely to be smaller.

The following documents will be followed during the use of drilling fluids:

Code of Practice for Constructing and Abandoning CSG Wells and Associated Bores In

Queensland (DNRM 2013)

CSG production wells will be designed, constructed and decommissioned in accordance with the

“Code of Practice for constructing and abandoning coal seam gas wells and associated bores in

Queensland” (DNRM 2013). This code outlines mandatory requirements and good practice to

reduce the risk of environmental harm. CSG production wells will be designed to:

� Prevent any interconnection between hydrocarbon bearing formations and aquifers;

� Ensure that gas is contained within the well and associated pipework and equipment

without leakage;

� Ensure zonal isolation between different aquifers is achieved; and

� Not introduce substances that may cause unlawful environmental harm

Work Method Statements

Standard Operating Procedures will be followed for sump-less drilling and mud mixing during the

drilling process. These procedures will include the following:

� Sumpless drilling – drilling fluids and mud are stored in portable, temporary tanks;

� The use of bunds at surface;

� Regular site inspections, monitoring and recording mud returns, monitoring and recording

mud volumes in tanks daily; and

� Undertaking daily drillers instructions.

7.1.2 Chemical Storage

All applicable materials will be stored and handled in accordance with the relevant legislative

requirements and Australian Standards including, but not limited to the provisions of:

� AS 3780:2008 – The storage and handling of corrosive substances; and

� AS 3833:2007 – Storage and handling of mixed classes of dangerous goods in packaged and

intermediate bulk containers.

The EMP (Senex 2017d; Attachment F) outlines the management measures for chemical storage,

these include:

� An inventory of all chemicals maintained on each site is to be maintained by the Senex Site

Supervisor;

ERM





Page 55


� Safety Data Sheets (SDS) are to be maintained on site at all times and for all chemicals;

� Storage areas must be sealed, bunded, and adequately ventilated;

� Storage areas will be preferentially located away from watercourses and sensitive areas;

� Substances not in use are to be sealed and safely stored in a secure area;

� Containment bunds and/or sumps will be drained periodically of accumulated rainwater to

prevent overflow and subsequent pollution of the surrounding land and watercourses.

7.1.3 Environmental Management Practices

The following documents provide guidance for best environmental practices with regards to siting

CSG wells and dealing with any environmental incidents:

Environmental Protocol for Field Development and Constraints Analysis (Senex 2016;

Attachment H)

This protocol aims to ensure that infrastructure siting considers biodiversity values and

environmental constraints when selecting preferential locations, aligning with planning principles

to avoid, minimise, mitigate and then manage potential environmental impacts. This will include

avoiding drilling within confirmed TECs including SEVT and Brigalow.

Environmental Management Plan (Senex 2017d; Attachment F)

The Environmental Management Plan describes how Senex will manage potential environmental

impacts associated with conducting exploration, appraisal and production activities in the WSGP

area and ensure compliance with EA conditions, industry guidelines and regulatory requirements.

Spill Response Plan (Senex 2017a; Attachment F)

Provides the standard protocols that must be utilised in order for Senex to respond in an

appropriate and timely manner in the event of a spill. The procedure provides a common system

and focus for spill response support and response hierarchy, which includes preserving life,

ensuring the safety of people, and minimising the impact on the environment.

7.2 Predicted Significance of Impacts

7.2.1 Potential Magnitude of Impact

The consequence of a chemical to MNES is based on the hazard characterisation of each chemical.

The drilling fluids that were characterised as potentially hazardous (Nuosept 78, Aldacide G,

Idcide-20 and Caustic soda), are mainly biocides, and they are readily biodegradable and do not

bioaccumulate. They were identified in Section 4.3 as being potentially harmful to very toxic to

fish, invertebrates and algae. The environmental consequence of each of these drilling fluids is

assessed in Table 7-2.

The magnitude of their potential impact has been assigned moderate to high, as they have the

potential to cause localized to regional scale impacts depending on the receptors. This is based on

high concentrations of chemical reaching a receptor. This is mainly due to their potential effect on

ecological communities and their long-term impacts on human health.

7.2.2 Significance of Impacts

The significance of impact on an MNES has been assessed based on:

� The likelihood of an impact reaching an MNES receptor; and

� The environmental consequence on the MNES receptor.

The significance of an impact is assessed prior to and following the application of management

and mitigation measures.

The full assessment is provided in Table 7-3. It is summarised below for each category of MNES.

Nationally Threatened and Migratory Species

Potential impacts were identified from above ground chemical spills, during CSG production well

drilling and from inappropriate reuse/disposal of drill cuttings and fluids.

ERM





Page 59


The potential consequence from drilling fluids has been rated as moderate, as impacts may result

in the loss of integrity of the attribute or loss of part of attribute but this is expected to be

localised.

The residual risk to MNES, after the application of management and mitigation measures in

Section 7.1, is concluded to be insignificant.

Surface Water



The consequence from drilling fluids has been rated as high, as impacts may result in the loss of

integrity of the attribute or loss of part of attribute regionally.

The residual risk to MNES, after the application of management and mitigation measures in

Section 7.1, is concluded to be low to insignificant.

Groundwater



The consequence from drilling fluids has been rated as high, as impacts may result in the loss of

integrity of the attribute or loss of part of attribute regionally.

The residual risk to MNES, after the application of management and mitigation measures, is

concluded to be low to insignificant.

8 LONG-TERM MONITORING AND REPORTING

8.1 Monitoring

8.1.1 Groundwater

Senex have developed a CSG Water Monitoring and Management Plan (Senex 2017c; Attachment

L), which outlines their proposed groundwater monitoring activities.

Senex are required as part of the Surat CMA UWIR WMS (under the Water Act 2000) to undertake

baseline assessments for 126 bores within the WSGP area. To date, baseline assessments have

been carried out for 89 bores during 2015 and 2016. Following several attempts, Senex were

unable to secure land access to assess the remaining 37 bores. Following a review of the baseline

assessment results, Senex may investigate the possibility of establishing a landowner monitoring

bore program, where suitability and access are available. The program would be dependent on

landowner access, suitability of the bore for monitoring and sampling and the screened aquifer.

The groundwater monitoring requirements for CSG tenure holders within the Surat CMA are

provided as part of the UWIR WMS (OGIA 2016b) which is prepared by the Office of Groundwater

Impact Assessment (OGIA). Senex’s groundwater monitoring locations have been selected and

agreed upon through consultation with OGIA, to complement the existing UWIR monitoring

network and monitoring of drawdown associated with the WSGP.

Senex have currently installed one of the three monitoring sites required (Glenora-4M, Glenora-

6M), with the remaining two sites (Tethys-6M, Tethys-7M and Pegasus-2M) scheduled for

installation in 2018. Senex also continue to monitor Glenora-24M, which was installed by the

previous tenure holder, however Glenora-4M has been installed to replace this facility.

The program will provide information to further understand the aquifer connectivity,

hydrogeological conditions and impacts associated with CSG Production within the WSGP.

8.1.2 Surface Water and GDEs

The Spring Ridge Complex is located within the Rhea development block of the WSGP. The spring

is considered to be associated with a perched aquifer within the Gubberamunda Sandstone. There

are no impacts predicted at this spring complex, however, to verify the groundwater model

predictions, monitoring bore Tethys-7M will be installed in the Gubberamunda Sandstone, to the

south of the complex (Senex 2017c; Attachment L).

8.1.3 Land and Soils

Under the CSG Water Management Plan Senex will undertake land and soil monitoring where CSG

water management activities have the potential to significantly impact on EVs (Senex 2017e;

Attachment K).

8.2 Reporting

Monitoring, auditing of, and reporting on, contractor and Senex on-site activities provides a direct

measure of Senex’s compliance with environmental regulations and EA conditions, together with

an indication of the effectiveness of the HSEMS, EMP and supporting procedures and plans.

ERM





Page 65


Environmental inspection, monitoring and auditing will be undertaken by the Senex Site

Supervisor and Senex Environmental representative on a periodic basis to assess whether

activities are in compliance with the requirements of these systems and documents (Senex 2017d;

Attachment F).

8.2.1 Data Management and Reporting

Data collected as part of any monitoring will be collated and stored in the Senex database system,

which will include any groundwater quality sampling results (Senex 2017c; Attachment L).

Senex and its contractors will maintain an appropriate and auditable record system.

Environmental reporting information will include as relevant:

� Inspection / monitoring reports;

� Photographic records;

� Training and induction attendance and associated dates;

� Incident reports;

� Remedial actions taken following incident reports;

� Records of waste removal including waste tracking certificates; and

� Audit reports.

All records and data required to be maintained by EA conditions will be retained for a minimum of

5 years. SDS records are kept by drilling contractors on site during each stage of drilling.

Drilling fluids are selected and managed to ensure all products are used in accordance with the

manufacturer’s recommendations and relevant SDS. The name, type and quantity of each drilling

fluid additive used on each well are recorded by Senex (Senex 2017d; Attachment F).

8.3 Review of Listed Chemicals

Senex will review the chemical risk assessment should:

� new drilling fluids and chemicals be proposed; and/or,

� the advice with regards to toxicology and hazardous nature of the proposed chemicals

changes as advised by drilling contractors.

The SDS which include the name, type and quantity of each drilling fluid additive used on each

well will be reviewed by Senex as they are updated by the manufacturer. Senex’s contractor

management systems and processes will ensure that any new drilling contractors or companies

undertaking works on site involving the handling and use of drilling fluids will be reviewed.

ERM





Page 66


9 SUMMARY OF POTENTIAL IMPACTS

KCB have undertaken a chemical risk assessment for chemicals to be used in coal seam gas

extraction as part of the WSGP CSG project. In summary:

� A total of 16 different chemicals are proposed to be used during the drilling, management

and abandonment of CSG wells;

� Seven chemicals were deemed to contain chemicals of a ‘hazardous’ nature as stated

within their SDS. These fluids were characterised further to understand the consequence

of the release of the chemical into the environment. Of these seven, four were solid and

insoluble and were removed from further characterisation as there is little to no risk that

these drilling ‘fluids’ will move off site to affect MNES.

� Further characterisation of the chemicals of concern was undertaken. These fluids were

Nuosept 78, Aldacide G, Idcide-20 and caustic soda. These chemicals are mainly biocides.

Most are readily biodegradable, and do not bioaccumulate. They are identified as being

harmful to very toxic to fish, invertebrates and algae. These chemicals were assessed as

having a potentially high magnitude of impact to ecosystems should they be directly

released to surface water.

� MNES present in the WSGP Project Area, and potential contaminant receptors, include

nationally threatened species and ecological communities such as Brigalow and semi-

evergreen vine thickets (SEVT), Curlew Sandpiper and Australian painted snipe; and water

resources including Great Artesian Basin aquifers such as the Gubberamunda Sandstone

and their groundwater users, ephemeral surface water systems and groundwater

dependent ecosystems

� The risk to MNES from chemicals comes from above ground chemical spills, the loss of

chemicals to aquifers below ground, and the eventual disposal of the drilling fluids. These

risk events have the potential to impact MNES by:

� Contamination of habitat for species that inhabit surface waterbodies (e.g. Latham’s

snipe, Australian painted snipe) whether directly or as a result of runoff from adjacent

spills;

� Contamination of drinking (surface water) resources for threatened species (e.g.

Squatter pigeon and Painted honeyeater) whether directly or as a result of runoff from

adjacent spills; or

� Contamination of groundwater systems which may support groundwater dependent

ecosystems such as terrestrial vegetation and wetlands; may be hydraulically

connected to surface water systems or directly abstracted for consumption.

� One-dimensional contaminant transport modelling has been undertaken to assess the

potential contaminant levels at receptors. This modelling concluded that at a receptor

200 m from the CSG well, if a loss of drilling fluid occurred down the bore, after 400 years

the potential contaminant concentration is still lower than the concentrations required to

negatively impact aquatic life. The modelling did not incorporate sorption or degradation

of the drilling fluid chemicals.

� A number of mitigation and management methods have been identified to reduce or

eliminate risk from drilling fluids. Senex apply a number of management and mitigation

measures to reduce the risk to MNES. These include drilling protocols such as the Code of

Practice for Constructing and Abandoning CSG Wells and Associated Bores in Queensland

(DNRM 2013), and environmental management practices such as the Environmental

Protocol for Field Development and Constraints Analysis (Senex 2016; Attachment H), an

Environmental Management Plan (Senex 2017d; Attachment F) and a Spill Response Plan

(Senex 2017a; Attachment F).

The risk to MNES receptors from drilling fluids was determined both prior to, and following,

mitigation and management measures. The final risk assessment determined that the likelihood

for a drilling fluid to adversely affect an MNES is highly unlikely to unlikely due to the controls in

place during drilling and the protocols in place if a spill did occur. The overall risk to MNES has

been assessed as low significance to insignificant.

MEMO TO: Brent Usher COMPANY: Klohn Crippen Berger

FROM: Adam Pratt PROJECT TITLE: Western Surat Gas Project - Chemical Risk Assessment

DATE: 4/10/2017 PROJECT & DOCUMENT NO: KCB-001 001

SUBJECT: Peer Review of the Chemical Risk Assessment for the Western Surat Gas Project

1 INTRODUCTION

Soilwater Consultants (SWC) were engaged by Klohn Crippen Berger (KCB) to peer review the Chemical Risk Assessment (KCB, 2017; the Document) for Section 6 of the Public Environmental Report (PER) for the Western Surat Gas Project (WSGP) being proposed by Senex Energy. This Chemical Risk Assessment only considered impacts to Matters of National Environmental Significance (MNES) from drilling fluids used in the initial drilling, maintenance and decommissioning of Coal Seam Gas (CSG) production wells associated with the WSGP. The Risk Assessment did not consider human health or occupational impacts of these chemicals or potential impacts of chemicals used in other aspects of the WSGP outside of this scope.

This peer review was a required item of Section 6 of the PER as specified by the Department of Environment and Energy (DotEE).

1.1 RELEVENT EXPERTISE

This peer review of the Chemical Risk Assessment was undertaken by Adam Pratt, Director and Principal Geochemist for SWC. Adam has over 20 years’ experience conducting environmental risk assessments for the resources sector throughout Australia and internationally. Adam’s field of expertise covers ecosystem function and solute / contaminant movement through the environment and impacts on surface and groundwater dependant environmental receptors. He therefore has the required experience to conduct this Risk Assessment.

2 PEER REVIEW FINDINGS

The pertinent findings from this peer review include:

The Chemical Risk Assessment undertaken by KCB adequately addresses all required components of Section 6 of the PER.

WESTERN SURAT GAS PROJECT - CHEMICAL RISK ASSESSMENT

F:\KCB Western Surat Gas Project\Chemical Risk Assessment - Peer Review 171004.docx Page 2 of 2

The Risk Assessment undertaken by KCB follows the appropriate, and most up-to-date national and international standards, including AS/NZS 4360:2004, AS/NZS ISO 31000:2009; US EPA (2014) Toolbox for Exposure Assessments and the OECD (2014) Environmental Risk Assessment Toolkit.

The Risk Assessment adequately covers the Hazard Identification, Hazard Characterisation, Exposure Assessment and Risk Characterisation of the chemicals present in the proposed drilling fluids, and thus is sufficient to assess the risks to the MNES.

The Risk Assessment adequately describes the various MNES that may potentially be impacted by the WSGP and their environmental requirements.

The Risk Assessment provides an adequate description of the source-pathway-receptor model for the various chemicals used, and thus the Exposure Assessment undertaken is sufficient to assess the risk of impact on MNES.

The likelihood and consequence levels used in the Risk Assessment, and the resulting Risk Rating, are fit-for-purpose and adequately capture the risk of impact on MNES.

The mitigation and management measured identified in the Risk Assessment are considered sufficient to manage any potential risks, particularly given the likelihood of impact on MNES is generally low to insignificant for most chemicals used in the drilling fluids.

3 CONCLUSIONS

Following peer review of the Chemical Risk Assessment undertaken by KCB for the drilling fluids to be used in the WSGP, it is considered that the conclusions are accurate and reliable, and that drilling fluids pose a low to insignificant risk to MNES located within or in close proximity to the WSGP. Potential impacts are expected to be minimal given the low to very low likelihood that the chemicals will interact with the MNES, and the proposed monitoring, mitigation and management measures identified in the Risk Assessment are considered adequate to protect the MNES and ensure that no future impact occurs.

Should you have any queries regarding this peer review, please do not hesitate to contact us.

Yours sincerely,

Adam Pratt

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.




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

AdditionalInformation

EXPOSURE CONTROL: If utilised in a closed system the potential for over exposure is reduced. If not used in aclosed system, local exhaust ventilation is recommended to control exposure. Provide eye wash and safetyshower in close proximity to points of potential exposure. Where the potential for an inhalation risk exists, anapproved respirator may be required. Do not eat, store, consume food, tobacco or drink in areas where product isused.

RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoidexposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken.Remember that some respirators may be extremely uncomfortable when used for long periods. The use of airpowered or air supplied respirators should be considered where prolonged or repeated use is necessary.

8. EXPOSURE CONTROLS / PERSONAL PROTECTION

General No exposure standard has been established for this product by the Safe Work Australia (SWA).However, the exposure standard for dust not otherwise specified is 10mg/m3 (for inspirable dust) and 3mg/m3 (for respirable dust). NOTE: The exposure value at the TWA is the average airborne concentration of a particular substance when calculated over a normal 8 hour working day for a 5 day working week.These exposure standards are guides to be used in the control of occupational health hazards. All atmospheric contamination should be kept to as low a level as is workable. These exposure standards should not be used as fine dividing lines between safe and dangerous concentrations of chemicals. They are not a measure of relative toxicity.

Exposure Limits No Data Available

Biological Limits No information available on biological limit values for this product.

Engineering Measures A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Adequate ventilation should be provided so that exposure limits are not exceeded.

Personal Protection Equipment RESPIRATOR: Air –purifying (half-mask / full-face) respirator with cartridges / canister approved for use against dusts, mists and fumes (AS1715/1716). EYES: Protective glasses or goggles should be worn when this product is being used (AS1336/1337).HANDS: Wear suitable impervious elbow-length gloves (AS2161).CLOTHING: Long-sleeved protective clothing and safety footwear (AS3765/2210).

Thoroughly launder protective clothing before storage or re-use. Advise laundry of nature of contamination when sending contaminated clothing to laundry.

Information on Toxicological Effects Acute Toxicity

InhalationInhaled crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (IARC, Group1). There is sufficient evidence in experimental animals 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 causenoticeable injury or illness even though permanent lung damage may be occurring. Inhalation of dust may also have seriouschronic health effects (See "Chronic Effects/Carcinogenicity" subsection below).

Eye ContactMay cause mechanical irritation to eye.Skin ContactNone known.IngestionNone known.

_____________________________________________________________________________________________Page 5 / 8

Chronic Effects/CarcinogenicitySilicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lungdisease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reducedpulmonary 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) has determined that crystalline silica inhaled in the formof quartz or cristobalite from occupational sources can cause lung cancer in humans (Group 1 - carcinogenic to humans) and hasdetermined that there is sufficient evidence in experimental animals for the carcinogenicity of tridymite (Group 2A - possible

_____________________________________________________________________________________________


carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction withthe use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a humancarcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists(ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2). There is some evidence that breathingrespirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints suchas scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidneydisease.
