2.0 DESCRIPTION OF THE ACTIVITY

2.1 Scope The scope of this document includes the environmental aspects of all Perth Basin WIAs within AWE Perth Pty Ltd permit areas (Figure 1).

The activities listed in Sections 2.3 to 2.7 of this document could potentially be conducted on all wells in the Perth Basin.

2.2 Location There are potentially fifty-five (55) wells (plus any new drilled wells) that could be worked over in the Perth Basin. Forty-four (44) of these wells are located on cleared farmland; and eleven (11) are located within Nature Reserve (Figure 2 to Figure 5).

2.3 WIA related activities The WIA related activities include:

• Possible modifications to the existing well site pad area to ensure the ground can support the WIA, and ancillary equipment; • Mobilisation of WIA Equipment, personnel and supplies to and from the site; • Conducting the WIA; • Demobilisation of WIA Equipment, personnel and supplies; and • Restoration of the site following the completion of activities. 2.4 Well Intervention Activities WIA are remedial operations undertaken by MEPAU to maintain maximum oil or gas producing rates and well integrity. WIA are any operation carried out on an oil or gas well during, or at the end of its productive life, that alters the state of the well and or well geometry, provides well diagnostics or manages the production of the well. The types of WIA conducted on the Perth Basin Production facilities can be summarised as follows:

• General WIA (covered under this EP): • Wellhead Maintenance; • Pumping; • Wireline/Slickline operations; • Well diagnostics; and • Acid wash treatments. • WIA requiring an Environmental Bridging Document: • Pulling and Replacing a Completion; • Snubbing; • Coiled tubing; • Well workover; • Well testing; • Remedial Cement Squeezing; and • Plug and Abandonment. 2.4.1 Timeframes

WIA generally run for approximately 14 days or less (including both mobilisation/demobilisation time). Noise and light disturbance to surrounding landowners is not generally a concern due to the remote location of the wells and due to WIA being typically conducted during daylight hours.

2.4.2 Chemical Disclosure for Products, Additives, Chemicals and Other Substances

DMIRS set out the requirements for chemical disclosure within the Chemical Disclosure Guideline released August 2013. The guideline details the chemical disclosure requirements for products, additives, chemicals and other substances used ‘down-hole’ in petroleum or

HSE-E-075-SUM Rev 4 Page 15 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

geothermal related activities regulated under regulation 15(9) of the Petroleum and Geothermal Energy Resources (Environment) Regulations 2012.

For General WIA requiring down-hole chemical use (refer to Section 2.4), the proposed chemicals are outlined within the disclosure tables within Appendix 1 and the corresponding Safety Data Sheets are listed within Appendix 2.

2.4.3 Decommissioning (Plug and Abandonment) Activities

When a well has reached the end of its life due to economic, integrity or reservoir reasons, the well will be decommissioned. The objective of decommissioning operations is to isolate the reservoir communication via the wellbore to surface as well as any other zones that may be in communication with the well. Well decommissioning is undertaken in accordance with the applicable Well Management Plan approved under the Petroleum and Geothermal Energy Resources (Resource Management and Administration) Regulations 2015.

2.5 Demobilisation Upon completion of the WIA work scope, all WIA equipment, personnel and supplies will be demobilised. Equipment will be transferred to the next WIA location or stacked awaiting further work.

2.6 Rehabilitation A rehabilitation EP will be submitted to the DMIRS for approval within 12 months of well decommissioning. Rehabilitation will commence as soon as practicable, usually within two years of the well decommissioning.

2.7 Utilities and Services The utilities and services for WIA are described below.

2.7.1 Water

Water cartage equipment for WIA includes a mobile tanker (38 kL) and two to four (depending on well volume) cylindrical and / or open-topped water tanks (16 to 60 kL sized) for the storage of water at a well site. The water is supplied by licensed onsite water bores or to the site via mobile truck mounted water tankers either collected from the HPF or Dongara townsite.

Bottled drinking water is supplied and available to personnel at the site office.

2.7.2 Refuelling

Diesel fuel is delivered by mobile diesel tank (mounted on a 4WD vehicle) to equipment diesel tanks on site. Refuelling will occur at the WIA site. Storage of flammable or combustible liquids will be designed to contain not less than 110% of the volume of the largest storage vessel, and at least 25% of the total volume of substances stored.

HSE-E-075-SUM Rev 4 Page 16 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

For small WIA, if refuelling is required, it will be via a vehicle-mounted mobile diesel tank or portable cans. For larger WIA, a dual skinned diesel tank is set up for refuelling the mobile tank with bulk fuel being delivered by an off-site contractor.

2.7.3 Electricity

Portable on-site diesel generation provides power during WIA.

2.7.4 Offices and Storage Areas

Temporary offices, workshops and storage areas for typical WIA are as follows:

• 37 m3 (2.4 mW x 6 mL x 2.6 mH) break room • 20 m3 (2.4 mW x 3.2 mL x 2.6 mH) Rig Manager/HSE office • 20 m3 (2.4 mW x 3.2 mL x 2.6 mH) Company Man office • 20 m3 (2.4 mW x 3.2 mL x 2.6 mH) workshop • 50 m3 (2.4 mW x 7.9 mL x 2.6 mH) workshop Additional ancillary offices or work areas may be supplied by the Lead Contractor or MEPAU depending on the nature and scale of the WIA.

2.7.5 Chemical Storage

The chemicals required for WIA will be stored and handled as follows:

Onsite storage:

• A Lease Liner (polypropylene composite) (maximum infiltration rate: 10-9 m/s) will be in place for each well and used as a means of secondary containment for the returned fluids expected as part of the well-decommissioning activity. The polypropylene composite Lease Liner is four times more puncture resistant than commonly used HDPE liners, and its nonslip surface helps prevent slips and falls. The liner is a three- layer polypropylene composite consisting of three barrier films sandwiched by double layers of needle punched geotextile with heat fused surfaces. • The WIA fluids will be mixed onsite within a water cart, a mud mixing tank or storage vessel(s) with secondary containment (Lease Liner and/or drip trays) to capture any spillage should it occur. The chemicals will be stored in the portable bunding as described above. The process of mixing chemicals on location will be supervised by site personnel. Secondary containment for freshwater storage is not required. • Chemical storage (environmentally hazardous) will be within a 20 ft internally bunded Dangerous Goods container. Storage of flammable or combustible liquids will be designed to contain not less than 110% of the volume of the largest storage vessel, and at least 25% of the total volume of substances stored. • Liquid hydrocarbon products such as lubricants will be stored within bunded pallets or the 20 ft internally bunded Dangerous Goods container designed to contain not less than 110% of the volume of the largest storage vessel. Offsite storage:

HSE-E-075-SUM Rev 4 Page 17 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

• WIA chemicals stored offsite will be stored at the Hovea Production Facility Chemical Shed (this is a permanent bunded storage shed) or within a lease liner. Dangerous Goods are stored in compliance with the Dangerous Goods Site Licence (DGS016892). 2.7.6 Waste Disposal

WIA waste will be disposed of in accordance with the Landfill Waste Classification and Waste Definitions 1996 (as amended 2018) and the Perth Basin Waste Management Plan [PB-HSE- PLN-001] as summarised in Table 2.

3.0 DESCRIPTION OF THE ENVIRONMENT

3.1 Physical Environment 3.1.1 Climate

The WIA are located across the permit areas in the Perth Basin region, situated approximately 300 km north of Perth (Figure 1). The region has a Mediterranean-type climate characterised by seasonal patterns of hot, dry summers and mild, wet winters. The area is subject to high wind speeds, dust storms, lightning storms, high summer temperatures and low winter night temperatures.

3.1.2 Soil

Generally, soils within the Perth Basin are light and sandy and well drained. Beard (1976) described the soils as “calcareous sand soils of minimal development”. The soils consist of calcareous and siliceous sand underlain by aeolianite, which is often exposed.

The Perth Basin is situated entirely within the Geraldton Sandplains Biogeographical Region. Within this region, three broad physiographical units are recognised; the Swan Coastal Plain, the Arrowsmith Region and the Dandaragan Plateau. The areas in which WIA will be undertaken will generally be located entirely within the Swan Coastal Plain unit, which forms an elongated strip approximately 40 km wide running along the coast.

3.1.3 Surface and Groundwater Systems

The hydrology of the region is dominated by the landform units described in Section 3.1.2. Drainage is westward but the Irwin River valley to the north of the region is the only major coordinated drainage indentation. A number of swamps surrounded by dense scrub, frequent limestone outcrops and the occasional laterite outcrop are the other major features in the region. The sub-surface geology of the area consists of the Late Jurassic Yarragadee Formation, which is overlain by Tertiary Sediments. Groundwater is present in the Tertiary Sediments and the Yarragadee Formation, and the groundwater level is near, or at surface in the aforementioned swamps and low-lying areas, following the surface topography, but with lower relief. The porous and permeable coastal limestone and dune systems tend to allow rainwater to percolate vertically to the water table rather than running laterally off the surface.

3.2 Biological Environment Information on the fauna assemblage of the Perth Basin Permit WIA areas was drawn from a wide range of sources. These included State and Federal government databases. Databases accessed were the DPaW Naturemap (incorporating the Western Australian Museum’s Fauna Base and the DPaW Threatened and Priority Fauna Database), BirdLife Australia’s Atlas Database (BA), the EPBC Protected Matters Search Tool and the BCE database as described in Sections 3.2.1 to 3.2.9.

HSE-E-075-SUM Rev 4 Page 20 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

3.2.1 WA Biodiversity Search

A WA Biodiversity search (Naturemap) – Department of Parks and Wildlife (DPaW) was conducted (12/11/2018), a summary of the conservation significant species identified within the permit areas is provided (Table 3).

Listed Migratory Species 50 Refer to Section 3.2.9 for likely occurrence.

HSE-E-075-SUM Rev 4 Page 21 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

3.2.3 Conservation Area

The Department of Biodiversity, Conservation and Attractions (DBCA) manages 23 million hectares of national parks, conservation parks, regional parks, nature reserves, state forest and timber reserves in WA. DBCA manages these areas for the conservation of biodiversity in ecosystems within these areas. Major conservation areas across the MEPAU Perth Basin permit areas (refer to Figure 6). Wells within Nature Reserves are Drakea-02 (Yardanogo Nature Reserve), East Lake Logue 01 & 02, Woodada-06, 08, 11, 12, 14, 15, 16 and 19, and Woodada Deep-01 (Lake Logue Nature Reserve) (Figure 4).

3.2.3.1 Red Book

Red Book recommendations, released by the EPA between 1976 and 1984, were made on areas to be classed as conservation reserves. These EPA tenures are part of a listing of Crown Land areas identified in 'Conservation Reserves for Western Australia' and identify different systems which the EPA considered to be of environmental significance and proposed conservation areas.

The proposed WIA will not be within any Red Book areas.

HSE-E-075-SUM Rev 4 Page 23 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

3.2.4 Environmentally Sensitive Areas

Environmentally Sensitive Areas (ESAs) are declared under the Environmental Protection (Clearing of Native Vegetation) Regulations 2004 and cover:

• Declared World Heritage property sites; • An area that is registered on the Register of the National Estate; • A defined wetland and the area within 50 m of the wetland; • The area covered by vegetation within 50 m of rare flora; • The area covered by a threatened ecological community; • Bush Forever sites; • The areas covered by the following policies: • the Environmental Protection (Gnangara Mound Crown Land) Policy 1992 • the Environmental Protection (Western Swamp Tortoise Habitat) Policy 2002 • The areas covered by the lakes to which the Environmental Protection (Swan Coastal Plain Lakes) Policy 1992 applies; • Protected wetlands as defined in the Environmental Protection (South West Agricultural Zone Wetlands) Policy 1998. • Areas of fringing native vegetation in the policy area as defined in the Environmental Protection (Swan and Canning Rivers) Policy 1997 The potential WIA wells are located within the Perth Basin permit areas (Figure 4). Wells within ESAs are East Lake Logue 01 & 02, Woodada-06, 08, 11, 12, 14, 15, and 16 and Woodada Deep-01.

3.2.5 Groundwater Dependent Ecosystems

A previous Groundwater Dependent Ecosystem (GDE) study was undertaken by Rutherford et al (2005) for the Northern Perth Basin. This study considered sites to be potentially reliant on groundwater only if the depth to groundwater was less than 20 m. Any remnant vegetation in areas of shallow groundwater could potentially be groundwater dependent. Most areas across the permits are classified as having low/moderate potential for GDEs (BoM, 2018).

3.2.6 Vegetation Communities and Flora

The Perth Basin is located within the Irwin Botanical District (Northern Sandplains Region), within the Southwest Botanical Province as defined by Beard (1976). Under the Interim Biogeographic Regionalisation for Australia (IBRA) (Environment Australia 2000), the area lies on the Geraldton Sandplain, which is described as ‘mainly proteaceous scrub-heaths, rich in endemics, on the sandy earths of an extensive, undulating, lateritic sandplain mantling Permian to Cretaceous strata’.

Vegetation surveys have been undertaken in the Perth Basin in support of petroleum activities and include surveys. Vegetation in the region ranges from native vegetation with

HSE-E-075-SUM Rev 4 Page 24 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

little or no disturbance in the Beekeepers, Yardanogo and Lake Logue Nature Reserves to cleared areas for broad acre cropping and grazing with little remnant native vegetation. A summary of the Threatened Flora across the region is provided in the following sections.

3.2.6.1 Threatened Ecological Communities (TECs)

The EPBC Act Protected Matters Search identified three Listed TECs likely to occur within the Permit areas as listed below:

• Banksia Woodlands of the Swan Coastal Plain ecological community (Endangered) • Eucalypt Woodlands of the Western Australian Wheatbelt (Critically Endangered) • Subtropical and Temperate Coastal Saltmarsh (Vulnerable) As WIA are on existing sites, which require minimal clearing, the potential risk of impacting TECs is low.

3.2.6.2 Declared Rare Flora (DRF)

A desktop search of the Declared Rare Flora List (DBCA, Threatened and Priority Flora List, 2018), identified 122 Threatened Flora2 distributed across the Mid-west region.

WIA are on existing sites, which require minimal clearing. AWE has a clearing permit (CPS 8207) to cover the clearing of native vegetation regrowth in the Woodada Gas Field area. A targeted flora and vegetation survey will be contracted for clearing of native vegetation where no clearing permit (or clearing exemption) is in place. The survey will include a search for the presence of Threatened Flora.

3.2.7 Weeds

Weeds commonly found across the key Perth Basin permit areas are summarised in the following text.

L1/L2

A total of 38 weed taxa were recorded within a recent weed assessment of Waitsia-03 (Permit L1). Of these taxa, three are rated as High under the EWSWA (CALM 1999) and are therefore considered to be significant weed species. There were no taxa listed as a Declared Pests under BAM Act (DAF 2017) or WoNS (AWC 2017) recorded during the survey (Woodman, 2017).

The L2 permit areas consist mainly of previously cleared agricultural land (excluding the Dongara /Beekeepers Nature Reserves). The common weed species found across the Dongara region Golden Crownbeard (Dongara Daisy) Verbesina encelioides, African Boxthorn

2 Threatened Flora - Specially protected under the Wildlife Conservation Act 1950, listed under Schedules 1, 2 and 3 of the Wildlife Conservation (Rare Flora) Notice (which may also be referred to as Declared Rare Flora).

HSE-E-075-SUM Rev 4 Page 25 of 61 Perth Basin Well Intervention Activities Environment Plan Summary

Lycium ferocissimum Miers, African Love Grass Eragrostis curvula (Schrad.) Nees, Walkaway Burr Cenchrus echinatus L. (Shire of Irwin, Pest Plant Advice Notes).

L4/L5

Weed foliage cover is low at the majority of sites assessed (total weed covers of 5% or less) with the exception of Woodada-02 and sumps and drainage gullies associated with a number of well pads. The majority of the tracks around Woodada had only scattered minor weeds. However, there were some areas along the tracks which had a high cover of weeds (Woodman, 2012).

3.2.8 Dieback

The project area lies at the northern limit of the portion of Western Australia where significant plant disease caused by Phytophthora cinnamomi is known to occur. The environmental conditions of the area significantly affect the pathogens ability to survive or flourish and spread over time. All land with an annual average rainfall of more than 400 millimetres and suitable soil composition is considered vulnerable to Phytophthora Dieback (Department of Parks and Wildlife, 2015).

Dieback is known to occur in permit areas L4 and L5. Phytopthora cinnamomi, the most destructive species, is known to occur over a large area in Eneabba Creek and Lake Logue and at several small sites along the Leeman and Erindoon Roads (Glevan Consulting, 2012).

3.2.9 Fauna

Fauna diversity is closely aligned with landform-vegetation characteristics.

The area surrounding the L1/L2 permits is predominantly pasture land. Broad-acre cropping and sheep and cattle grazing predominate. The Waitsia wells are generally within existing cleared land (although there was clearing to establish the Waitsia-03 site).

A recent desktop survey identified 251 vertebrate fauna species as potentially occurring in the survey area and this assemblage included 30 species of conservation significance (Bamford, 2015). Of those species, only 7 conservation significant are considered likely to use the broader area on a regular basis (see Table 5).

However, based on the habitats present, only 10 of these species have a medium or high likelihood of occurrence within the survey area. The majority of the remaining species with a low likelihood of occurrence within the survey area consist of waterbirds and waders that have been recorded in previous surveys and databases based on the general region (Eastern Great Egret, Cattle Egret, Glossy Ibis, Eastern Osprey, White‐bellied Sea‐eagle, Hooded Plover, Terek Sandpiper, Common Sandpiper, Common Greenshank, Wood Sandpiper, Red‐necked Stint, Sharp‐tailed Sandpiper, and Curlew Sandpiper). These species may occur in the nearby Lake Logue and associated lakes. (Ecologia, 2011)

There is no significant native fauna habitat which could be impacted by the proposed WIA. Although protected fauna is known to reside within the broader region, the WIA are within agricultural or highly disturbed land, only minimal clearing of native vegetation is proposed and there are limited activities taking place outside of established sites or fenced compounds therefore impacts to native fauna are anticipated to be negligible.

3.3 Heritage 3.3.1 Aboriginal Heritage

MEPAU will abide by the provisions of the WA Aboriginal Heritage Act 1972. Field and desktop ethnographic surveys have been carried out to determine if operations are likely to impact upon areas of cultural heritage significance.

A search of the Aboriginal Heritage Inquiry System – Department of Aboriginal Affairs (Desktop search), across all permit areas identified the sites depicted within Figure 7. As a result of the field and desktop surveys it has been established that except for the Irwin River (Site 18907), the individual well sites where WIA could occur do not overlap any registered sites or any areas of significance to the Aboriginal people who participated in the process. There are 15 WIA wells in the Dongara region are <1 km from the Irwin River (Site 18907).

3.3.2 European Heritage

A State Heritage Register – Heritage Council – www.stateheritage.wa.gov.au search was completed (19/11/2018). A total of 16 State Registered Heritage Sites are found within the Irwin Shire, the majority within the immediate Township of Dongara.

The Australian Protected Matters Search Tool referenced in Section 3.2.2 also provides information regarding National Heritage Places, Commonwealth Heritage Places, and World Heritage Properties. No Commonwealth Heritage Places or World Heritage Properties were within 65 kilometres of the petroleum activity area. One National Heritage Place (Lesueur National Park) is within proximity to EP455, however there is currently no wells within the EP455 permit.

3.4 Socio-economic Environment The Mid West region has a diversified economy that varies with the geography and climate. Near the coast, annual rainfall of between 400 and 500 millimetres allows intensive agriculture. Further inland, annual rainfall decreases to less than 250 millimetres and here the economy is dominated by mining of iron ore, gold, nickel and other mineral resources.

The nearest townships to the Perth Basin Permit Areas are the town of Dongara - Port Denison (L1/L2) and Eneabba (L4/L5).

4.0 ENVIRONMENTAL RISK ASSESSMENT AND MANAGEMENT

4.1 Risk Management and Justification of ALARP The approach undertaken towards risk management for each aspect involves a review of the residual risk post treatment to determine if the environmental impacts and risks of the activity will be managed to an acceptable level. Where additional implementation measures are necessary to reach a level of acceptability they have been considered and adopted

The environmental risks and management identified for the WIA ranked medium or above are presented in Table 6.

4.2 Risk Classification and Reporting Requirements Under the definition in the Guideline for the Development of Petroleum and Geothermal Environment Plans in Western Australia, November 2016 in Western Australia the risk consequence of Moderate is equivalent to High on the MEPAU matrix.

THRU TUBING SYSTEMS SAFETY DATA SHEET Document # Version Prepared by: Issue Date: November 14, 2017 SDS – ACE Mix 1.1 Brad Cook Supersedes: All previous Cement (Portland/Oilwell) Page 3 of 12

Description of First Aid Measures General: Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show label if possible). Inhalation: When symptoms occur: go into open air and ventilate suspected area. Keep at rest and in a position comfortable for breathing. If you feel unwell, see medical advice. Skin Contact: Remove contaminated clothing. Immediately flush skin with plenty of water for at least 60 minutes. Immediately call POISON CENTER or doctor/physician. Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing for at least 60 minutes. Immediately call POISON CENTER or doctor/physician. Ingestion: Rinse mouth. Do not induce vomiting. Immediately call POISON CENTER or doctor/physician. Most Important Symptoms and Effects Both Acute and Delayed General: Corrosive to eyes, respiratory system and skin. Exposure may produce an allergic reaction. Inhalation: The three types of silicosis include: 1) Simple chronic silicosis – which results from long- term exposure (more than 20 years) to low amounts of respirable crystalline silica. Nodules of chronic inflammation and scarring provoked by the respirable crystalline silica form in the lungs and chest lymph nodes. This disease may feature breathlessness and may resemble chronic obstructive pulmonary disease (COPD); 2) Accelerated silicosis – occurs after exposure to larger amounts of respirable crystalline silica over a shorter period of time (5-15 years); 3) Acute silicosis – results from short-term exposure to very large amounts of respirable crystalline silica. The lungs become very inflamed and may fill with fluid, causing severe shortness of breath and low blood oxygen levels. Inflammation, scarring, and symptoms progress faster in accelerated silicosis than in simple silicosis. Progressive massive fibrosis may occur in simple or accelerated silicosis, but is more common in the accelerated form. Progressive massive fibrosis results from severe scarring and leads to the destruction of normal lung structures. Some studies show that exposure to repairable crystalline silica (without silicosis) or that the disease silicosis may be associated with the increased incidence of several autoimmune disorders such as scleroderma (thickening of the skin), systemic lupus erythematosus, rheumatoid arthritis, and diseases affecting the kidneys. Silicosis increases the risk of tuberculosis. Some studies show an increased incidence of chronic kidney disease and end-stage renal disease in workers exposed to respirable crystalline silica. Corrosive to the respiratory tract. Skin Contact: Cement may cause dry skin, discomfort, irritation, severe burns, and dermatitis. Exposure to sufficient duration to wet cement, or to dry cement on moist areas of the body, can cause serious potentially irreversible damage to skin, eye, respiratory, and digestive tracts due to chemical (caustic) burns, including third degree burns. A skin exposure may be hazardous even if there is no pain or discomfort. Cement is capable of causing dermatitis by irrigation and allergy. Skin affected by dermatitis may include symptoms such as; redness, itching, rash, scaling, and cracking. Irritant dermatitis is caused by the physical properties of cement including alkalinity and abrasion. Allergic contact dermatitis is caused by sensitization to hexavalent chromium (chromate) present in cement. The reaction can range from a mild rash to severe skin ulcers. Persons already sensitized may react to the

THRU TUBING SYSTEMS SAFETY DATA SHEET Document # Version Prepared by: Issue Date: November 14, 2017 SDS – ACE Mix 1.1 Brad Cook Supersedes: All previous Cement (Portland/Oilwell) Page 4 of 12

first contact with cement. Others may develop allergic dermatitis after years of repeated contact with cement. Eye Contact: Airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with large amounts of dry powder or with wet cement can cause moderate eye irritation, chemical burns, and blindness. Eye exposures require immediate first aid and medical attention to prevent significant damage to the eye. Ingestion: May cause burns or irritation of the linings of the mouth, throat, and gastrointestinal tract. Chronic Symptoms: If dust is generated, repeated exposure through inhalation may cause cancer or lung disease. Indication of Any Immediate Medical Attention and Special Treatment Needed If exposed or concerned, get medical advice and attention.

SECTION 5: FIRE-FIGHTING MEASURES Extinguishing Media Suitable Extinguishing Use extinguishing Media appropriate for surrounding fire. Media: Unsuitable Do not use a heavy water stream. Use of heavy stream of water may spread fire. Extinguishing Media: Special Hazards Arising From the Substance or Mixture Fire Hazard Not flammable. Explosion Hazard: Product is not explosive. Reactivity: Wet cement is alkaline and is incompatible with acids, ammonium salts, and aluminum metal. Cement dissolves in hydrofluoric acid, producing corrosive tetraflouride gas. Cement reacts with water to form silicates and calcium hydroxide. Silicates react with powerful oxidizers such as fluorine, boron triflouride, chlorine triflouride, manganese triflouride, and oxygen diflouride. Advice for Firefighters Precautionary Exercise caution when fighting any chemical fire. Measures Fire: Firefighting Do not get water inside containers. Do not apply water stream directly at source of leak. Instructions: Protection During Do not enter fire area without proper protective equipment, including respiratory Firefighting: protection. Hazardous None. Combustion Products: Reference to Other Sections Refer to Section 9 for flammability properties.

Other Important Information: Portland cement should only be used by knowledgeable persons. Inexperienced product users must obtain proper training before using this product. A key to using the product safely requires the user to recognize the Portland cement chemically reacts with water, and that some of the intermediate products of this reaction (that is, those present while a Portland cement product is “setting “) pose a far more severe hazard than does Portland cement itself. While the information provided in this Safety Data Sheet is believed to provide a useful summary of the hazards of Portland cement as it is commonly used, the sheet cannot, and does not, anticipate and provide all of the information that might be needed in every situation. In particular, the data furnished in this sheet does not address hazards that may be posed by other materials mixed with Portland cement products. Users therefore, should review other applicable material safety data sheets before working with this Portland cement or working on Portland cement or working Portland cement products, for example, Portland cement concrete.

16. OTHER INFORMATION

Additional information MINERAL OILS - NON REFINED: Animal experiments and human experience have shown cancer risks when handling mineral oils. Such cases are reported to have occurred in conditions where poor occupational hygiene practices resulted in prolonged skin contact. CLEANING MINERAL OIL CONTAMINATED CLOTHING: Cleaners are advised that when cleaning oil contaminated clothing it is essential that freshly distilled solvent is used for each batch, including final rinse, as even filtered solvent will leave oil residues.

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

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

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

EMERGENCY PHONE PRODUCT NAME 1-800-255-3924 BROMINE TRIFLUORIDE CAS #7787-71-5 TRADE NAME AND SYNONYMS Pipe Recovery Systems, Inc. Bromine Trifluoride UN - 1746 PACKING GROUP I Houston, Texas, USA CHEMICAL NAME AND SYNONYMS (713) 461-7770 Bromine Trifluoride

ISSUE DATE 04/78, 02/84 FORMULA CHEMICAL FAMILY REVISION DATE 5/95, 7/99, 8/02, 2/03, 4/04, BrF3 Fluoride 6/06, 6/07, 8/07, 05/09, 10/11 HEALTH HAZARD DATA TIME WEIGHTED AVERAGE EXPOSURE LIMIT See last page SYMPTOMS OF EXPOSURE Corrosive and extremely irritating to the upper and lower respiratory tracts, skin, and eyes. BrF3 hydrolyzes to form hydrofluoric acid, therefore skin burns and mucous membrane irritation are similar to those caused by the acid. Symptoms include tearing of the eyes, cough, difficult breathing, abnormal fluids formation in the nose, mouth and throat. Inhalation of BrF3 may cause pneumonitis ( deep lung inflammation) and pulmonary edema (abnormal fluid buildup in the lungs) which can be fatal. Symptons of hydrofluoric acid burns are severe pain, redness, possible swelling and tissue destruction. TOXICOLOGICAL PROPERTIES Bromine Trifluoride is irritating and corrosive to all living tissues. Toxic level exposure to skin tissue causes hydrofluoric acid burns and skin lesions resulting in tissue destruction and eventual scarring. Burn activity continues while any residual active remain. Chemical pneumonitis and pulmonary edema result from exposure to the lower respiratory tract and deep lung. Residual pulmonary malfunction might also occur. Burns of the eye result in lesions and possible loss of vision. Extended low level systemic absorption of fluorides may cause fluorosis, an abnormal calcium accumulation in the bone structure. RECOMMENDED FIRST AID TREATMENT PROMPT MEDICAL ATTENTION IS REQUIRED IN ALL CASES OF OVEREXPOSURE. BROMINE TRIFLUORIDE RESCUE PERSONNEL SHOULD BE EQUIPPED WITH APPROPRIATE PROTECTIVE EQUIPMENT (SELF-CONTAINED BREATHING APPARATUS, ETC.) TO PREVENT UNNECESSARY EXPOSURE. Inhalation: Move exposed personnel to an uncontaminated area. If not breathing, give artifical respiration, preferably mouth-to-mouth. If breathing is difficult, give oxygen. Keep victim warm and quiet. Assure that mucus or vomited material does not obstruct the airway by use of positional drainage. Delayed pulmonary edema may occur. Keep patient under medical observation for at least 24 hours. Eye Contact: PERSONS WITH POTENTIAL EXPOSURE TO BROMINE TRIFLUORIDE SHOULD NOT WEAR CONTACT LENSES. Flush contaminated eye(s) with large quantites of water. Hold eyelids open with fingers to assure complete flushing. Continue for minimum of 30 minutes. Skin Contact: Flush affected area with large quantities of water. Remove affected clothing as rapidly as possible. Skin burns may be treated with a calcium gluconate gel or slurry in water or glycerine. This compound binds the active fluorides in an insoluble form and limits burn extension and relieves pain. HAZARDOUS MIXTURES OF OTHER LIQUIDS, SOLIDS, OR GASES Bromine Trifluoride is a very reactive halogen fluoride. It reacts with virtually all organic and most inorganic substances. Some of the perfluorinated organic substances in their pure form will not be oxidized by Bromine Trifluoride. It reacts violently with water or fuels.

SECTION 4 FIRST AID MEASURES

Description of first aid measures

If this product comes in contact with the eyes:  Immediately hold eyelids apart and flush the eye continuously with running water.  Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Eye Contact  Continue flushing until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes.  Transport to hospital or doctor without delay.  Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. If skin or hair contact occurs:  Immediately flush body and clothes with large amounts of water, using safety shower if available.  Quickly remove all contaminated clothing, including footwear. Skin Contact  Wash skin and hair with running water. Continue flushing with water until advised to stop by the Poisons Information Centre.  Transport to hospital, or doctor.  If fumes or combustion products are inhaled remove from contaminated area.  Lay patient down. Keep warm and rested.  Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to Inhalation initiating first aid procedures.  Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary.  Transport to hospital, or doctor, without delay.  For advice, contact a Poisons Information Centre or a doctor at once.  Urgent hospital treatment is likely to be needed.  If swallowed do NOT induce vomiting.  If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. Ingestion  Observe the patient carefully.  Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious.  Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink.  Transport to hospital or doctor without delay.

Indication of any immediate medical attention and special treatment needed

Treat symptomatically. For acute or short term repeated exposures to strong acids:

 Airway problems may arise from laryngeal edema and inhalation exposure. Treat with 100% oxygen initially.  Respiratory distress may require cricothyroidotomy if endotracheal intubation is contraindicated by excessive swelling Intravenous lines should be established immediately in all cases where there is evidence of circulatory compromise.  Strong acids produce a coagulation necrosis characterised by formation of a coagulum (eschar) as a result of the dessicating action of the acid on proteins in specific tissues. INGESTION:

 Immediate dilution (milk or water) within 30 minutes post ingestion is recommended.  DO NOT attempt to neutralise the acid since exothermic reaction may extend the corrosive injury.  Be careful to avoid further vomit since re-exposure of the mucosa to the acid is harmful. Limit fluids to one or two glasses in an adult.  Charcoal has no place in acid management.  Some authors suggest the use of lavage within 1 hour of ingestion. SKIN:

 Skin lesions require copious saline irrigation. Treat chemical burns as thermal burns with non-adherent gauze and wrapping.  Deep second-degree burns may benefit from topical silver sulfadiazine. EYE:

 Eye injuries require retraction of the eyelids to ensure thorough irrigation of the conjuctival cul-de-sacs. Irrigation should last at least 20-30 minutes.  DO NOT use neutralising agents or any other additives. Several litres of saline are required.  Cycloplegic drops, (1% cyclopentolate for short-term use or 5% homatropine for longer term use) antibiotic drops, vasoconstrictive agents or artificial tears may be indicated dependent on the severity of the injury.  Steroid eye drops should only be administered with the approval of a consulting ophthalmologist).

Page 5 of 12

Issue Date: September 2017 SDS No: 722 Version: V.0.0.2 Conditions for safe storage, including any incompatibilities

 DO NOT use aluminium or galvanised containers  Check regularly for spills and leaks  Lined metal can, lined metal pail/ can. Suitable Container  Plastic pail.  Polyliner drum.  Packing as recommended by manufacturer.  Check all containers are clearly labelled and free from leaks.  Inorganic acids neutralise chemical bases (for example: amines and inorganic hydroxides) to form salts - neutralisation can generate dangerously large amounts of heat in small spaces.  The dissolution of inorganic acids in water or the dilution of their concentrated solutions with additional water may generate significant heat.  The addition of water to inorganic acids often generates sufficient heat in the small region of mixing to cause some of the water to boil explosively. The resulting "bumping" can spatter the acid.  Inorganic acids react with active metals, including such structural metals as aluminum and iron, to release hydrogen, a flammable gas. Storage Incompatibility  Inorganic acids react with cyanide compounds to release gaseous hydrogen cyanide.  Inorganic acids generate flammable and/or toxic gases in contact with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates.  Reacts vigorously with alkalis.  Reacts with mild steel, galvanised steel / zinc producing hydrogen gas which may form an explosive mixture with air.  Contact with acids, organics, reducing agents (eg. amines), metallic powders and heat sources produces toxic fumes of chlorine. May be decomposed by hot water releasing chlorine fumes.

SECTION 11 TOXICOLOGICAL INFORMATION

Information on toxicological effects

Acidic corrosives produce respiratory tract irritation with coughing, choking and mucous membrane damage. Symptoms of exposure may include dizziness, headache, nausea and weakness. Hydrogen chloride (HCl) vapour or fumes present a hazard from a single acute exposure. Exposures of 1300 to 2000 ppm have been lethal to Inhaled humans in a few minutes. Inhalation of aerosols (mists, fumes), generated by the material during the course of normal handling, may produce toxic effects; these may be fatal. Inhalation of the vapour is hazardous and may even be fatal. Ingestion of acidic corrosives may produce circumoral burns with a distinct discolouration of the mucous Ingestion membranes of the mouth, throat and oesophagus. Immediate pain and difficulties in swallowing and speaking may also be evident. Skin contact with acidic corrosives may result in pain and burns; these may be deep with distinct edges and may heal slowly with the formation of scar tissue. Skin contact with the material may damage the health of the individual; systemic effects may result following Skin Contact absorption. Open cuts, abraded or irritated skin should not be exposed to this material Entry into the blood-stream through, for example, cuts, abrasions, puncture wounds or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. When applied to the eye(s) of animals, the material produces severe ocular lesions which are present twenty -four hours or more after instillation. Direct eye contact with acid corrosives may produce pain, lachrymation, photophobia and burns. Mild burns of the Eye epithelia generally recover rapidly and completely. Severe burns produce long-lasting and possible irreversible damage. The appearance of the burn may not be apparent for several weeks after the initial contact. The cornea may ultimately become deeply vascularised and opaque resulting in blindness. Repeated or prolonged exposure to acids may result in the erosion of teeth, inflammatory and ulcerative changes in the mouth and necrosis (rarely) of the jaw. Bronchial irritation, with cough, and frequent attacks of bronchial pneumonia may ensue. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. Chronic Chronic minor exposure to hydrogen chloride (HCl) vapour or fume may cause discolouration or erosion of the teeth, bleeding of the nose and gums; and ulceration of the nasal mucous membranes. Repeated exposures of animals to concentrations of about 34 ppm HCl produced no immediate toxic effects. Workers exposed to hydrochloric acid suffered from gastritis and a number of cases of chronic bronchitis have also been reported. Repeated or prolonged exposure to dilute solutions of HCl may cause dermatitis.

11. TOXICOLOGICAL INFORMATION

11.1 Information on toxicological effects Acute toxicity May be harmful if swallowed. Oral Toxicity: An oral LD50 in rats of 2600 mg/kg was reported for potassium chloride. Additional toxicity data for potassium chloride: LD50 (Intraperitoneal): 620 mg/kg (mouse) LD50 (Intravenous): 117 mg/kg (mouse) LDLo (Ingestion): 20 mg/kg (man)

SDS Date: 16 Apr 2015 Page 3 of 6 Version No: 2.1 PRODUCT NAME POTASSIUM CHLORIDE

LDLo (Intraperitoneal): 900 mg/kg (guinea pig) LDLo (Intravenous): 77 mg/kg (guinea pig) LDLo (Subcutaneous): 2120 mg/kg (frog) TDLo (Ingestion): 60 mg/kg/days (woman) Skin Not classified as a skin irritant. Contact may result in mild irritation and rash. Eye Not classified as an eye irritant. Contact may cause mild irritation and lacrimation. Sensitization This product is not known to be a skin or respiratory sensitiser. Mutagenicity No evidence of mutagenic effects. Carcinogenicity No evidence of carcinogenic effects. Reproductive No evidence of reproductive effects. STOT – single Acute potassium poisoning via ingestion is rare as a large single dose usually induces vomiting, and exposure potassium is rapidly excreted by the body, however this product does have the potential to cause cardiovascular disorders. STOT – repeated Not classified as causing organ effects from repeated exposure. exposure Aspiration Not relevant.

12. ECOLOGICAL INFORMATION

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

12.2 Persistence and degradability Biodegradability does not pertain to inorganic substances.

12.3 Bioaccumulative potential Does not bioaccumulate.

12.4 Mobility in soil No impact if small amount is released to the soil.

12.5 Other adverse effects No information provided.

16. OTHER INFORMATION

Additional information RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. 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 air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

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

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

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

LD50 oral rabbit: 11,250 mg/kg. Biodegradation/bioaccumulation: Polyacrylamides are generally water-soluble, high molecular weight synthetic organic polymers that primarily interact with the clay fraction of soils. The degree of interaction depends on both the properties of the polymer and properties of the soil. For the most part, polyacrylamide is resistant to microbial attack, and its degradation is mainly through a physical breakdown. Polyacrylamide has been shown to be non-toxic to humans, animals, fish, and plants; the only concern has been the toxicity of its residual monomer (acrylamide) content, which is a known neurotoxin to humans. Polyacrylamide can also degrade to acrylamide under environmental conditions. The monomer degradable and does not accumulate in soils.

11.1 Information on toxicological effects Health hazard Slightly corrosive - irritant. This product has the potential to cause adverse health effects with over exposure. summary Use safe work practices to avoid eye or skin contact and inhalation. Once water is added, an inhalation hazard is not anticipated. Chronic respiratory effects are not anticipated with over exposure at high levels due to the immediate irritant and/or corrosive effects. Hexavalent chromium compounds are classified as carcinogenic to humans (IARC Group 1). Eye Corrosive - irritant. Contact may result in irritation, lacrimation, pain, redness, corneal burns and possible permanent damage. Severe irritant upon contact with powder/ dust. Inhalation Slightly corrosive - irritant. Over exposure may result in irritation of the nose and throat, coughing and bronchitis. Hexavalent chromium is reported to cause respiratory sensitisation, however due to the trace amount present, a hazard is not anticipated under normal conditions of use. Skin Slightly corrosive. Contact with powder or wetted form may result in rash and dermatitis. Some individuals may exhibit an allergic response upon exposure to cement, possibly due to trace amounts of chromium. Ingestion Slightly corrosive. Ingestion may result in burns to the mouth and throat, nausea, vomiting and abdominal pain. Ingestion is considered unlikely due to product form.

16. OTHER INFORMATION

Additional information RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. 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 air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

CEMENT CONTACT DERMATITIS - Individuals using wet cement, mortar, grout or concrete could be at risk of developing cement dermatitis. Symptoms of exposure include itchy, tender, swollen, hot, cracked or blistering skin with the potential for sensitisation. The dermatitis is due to the presence of soluble (hexavalent) chromium.

HEALTH EFFECTS FROM EXPOSURE: It should be noted that the effects from exposure to this product will depend on several factors including: frequency and duration of use; quantity used; effectiveness of control measures; protective equipment used and method of application.

SECTION 11- TOXICOLOGICAL INFORMATION

Principle route of exposure: Eye or Skin contact, Inhalation.

Inhalation: This dry powder blend contains crystalline silica and quartz. 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 experimental animals for the

carcinogenicity of tridymite (IARC, Group 2A).

This dry powder blend contains crystalline silica and quartz. Breathing silica dust may

cause irritation of the nose, throat and respiratory passages. Breathing silica may cause

noticeable injury or illness even through permanent lung damage may be occurring.

Inhalation of dust may also have serious chronic health effects (See “Chronic Effects /

Carcinogenicity” subsection below).

Skin Contact: Wet cement can dry skin and cause Alkali burns.

Eye Contact: Dust can irritate eyes.

Ingestion: No harmful affects known.

Medical conditions aggravated by exposure: Dermatitis

Silicosis: Excessive inhalation of respirable crystalline silica dust may

Chronic effects/ Carcinogenicity: cause a progressive, disabling and sometime-fatal lung disease called

silicosis. Symptoms include cough, shortened of breath, wheezing, non-

specific chest illness, and reduced pulmonary function. This disease is

exacerbated by smoking. Individuals will silicosis are predisposed to

develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC)

has determined that crystalline silica inhaled in the form of quartz or

crystallite from occupational sources can cause lung cancer in humans

(Group 1 – carcinogenic to humans) and has determined 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 Fibers (June 1997) in

conjunction with the use of these minerals. The National Toxicology

Program classifies respirable crystalline silica as “Known to be a human th carcinogen”. Refer to the 9 Report of 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 breathing respirable crystalline silica or the

disease silicosis is associated with an increased incidence of significant

endpoints such as acleroderma (an immune system disorder manifested

by scarring of the lungs, skin, and other internal organs) and kidney

disease.

This dry powder blend contains quartz, crystalline, silica and quartz. For

Other Information further information consult “Adverse Effects of Crystalline Silica
