6 Gorgon Project: Document No.: G1-PP-QRT-GDL Introduction 1.1 Proponent Chevron Australia Pty Ltd (Chevron Australia) is the proponent and the person taking the action for the Gorgon Gas Development on behalf of the following companies (collectively known as the Gorgon Joint Venturers): Chevron Australia Pty Ltd Chevron (TAPL) Pty Ltd Shell Development (Australia) Pty Ltd Mobil Australia Resources Company Pty Limited Osaka Gas Gorgon Pty Ltd Tokyo Gas Gorgon Pty Ltd Chubu Electric Power Gorgon Pty Ltd pursuant to Statement No. 800 and EPBC Reference: 2003/1294 and 2008/4178. Chevron Australia is also the proponent and the person taking the action for the Jansz Feed Gas Pipeline on behalf of the Gorgon Joint Venturers, pursuant to Statement No. 769, and EPBC Reference: 2005/ Project Chevron Australia proposes to develop the gas reserves of the Greater Gorgon Area (Figure 1-1). Subsea gathering systems and subsea pipelines will be installed to deliver feed gas from the Gorgon and Jansz Io gas fields to the west coast of Barrow Island. The feed gas pipeline system will be buried as it traverses from the west coast to the east coast of the Island where the system will tie in to the Gas Treatment Plant located at Town Point. The Gas Treatment Plant will comprise three Liquefied Natural Gas (LNG) trains capable of producing a nominal capacity of five Million Tonnes Per Annum (MTPA) per train. The Gas Treatment Plant will also produce condensate and domestic gas. Carbon dioxide (CO 2 ), which occurs naturally in the feed gas, will be separated during the production process. As part of the Gorgon Gas Development, Chevron Australia will inject the separated CO 2 into deep formations below Barrow Island. The LNG and condensate will be loaded from a dedicated jetty offshore from Town Point and then transported by dedicated carriers to international markets. Gas for domestic use will be exported by a pipeline from Town Point to the domestic gas collection and distribution network on the mainland. 1.3 Location The Gorgon gas field is located approximately 130 km and the Jansz Io field approximately 200 km off the north-west coast of Western Australia. Barrow Island is located off the Pilbara coast 85 km north-north-east of the town of Onslow and 140 km west of Karratha. The Island is approximately 25 km long and 10 km wide and covers ha. It is the largest of a group of islands, including the Montebello and Lowendal Islands. Chevron Australia Pty Ltd Public Page 9 Printed Date: 16 May 2014 Uncontrolled when Printed

9 Barrow Island Quarantine: Document No.: G1-PP-QRT-GDL Terminology, Definitions, and Abbreviations Terms and definitions that apply to this Quarantine Management System (QMS) are listed in Appendix Environmental Approvals The initial Gorgon Gas Development was assessed through an Environmental Impact Statement/Environmental Review and Management Programme (EIS/ERMP) assessment process (Chevron Australia 2005, 2006). The initial Gorgon Gas Development was approved by the Western Australian State Minister for the Environment on 6 September 2007 by way of Ministerial Implementation Statement No. 748 (Statement No. 748) and the Commonwealth Minister for the Environment and Water Resources on 3 October 2007 (EPBC Reference: 2003/1294). In May 2008, under section 45C of the Western Australian Environmental Protection Act 1986 (EP Act), the Environmental Protection Authority (EPA) approved some minor changes to the Gorgon Gas Development that it considered not to result in a significant, detrimental, environmental effect in addition to, or different from, the effect of the original proposal (EPA 2008). The approved changes are: excavation of a berthing pocket at the Barge (WAPET) Landing facility installation of additional communications facilities (microwave communications towers) relocation of the seawater intake modification to the seismic monitoring program In September 2008, Chevron Australia sought both State and Commonwealth approval through a Public Environment Review (PER) assessment process (Chevron Australia 2008) for the Revised and Expanded Gorgon Gas Development to make some changes to Key Proposal Characteristics of the initial Gorgon Gas Development, as outlined below: addition of a five MTPA LNG train, increasing the number of LNG trains from two to three expansion of the CO 2 Injection System, increasing the number of injection wells and surface drill locations extension of the causeway and the Materials Offloading Facility (MOF) into deeper water The Revised and Expanded Gorgon Gas Development was approved by the Western Australian State Minister for the Environment on 10 August 2009 by way of Ministerial Implementation Statement No. 800 (Statement No. 800). Statement No. 800 also superseded Statement No. 748 as the approval for the initial Gorgon Gas Development. Statement No. 800 therefore provides approval for both the initial Gorgon Gas Development and the Revised and Expanded Gorgon Gas Development, which together are known as the Gorgon Gas Development. Amendments to Statement No. 800 Conditions 18, 20 and 21 under section 46 of the EP Act were approved by the Western Australian State Minister for the Environment on 7 June 2011 by way of Ministerial Implementation Statement No. 865 (Statement No. 865). Therefore, implementation of the Gorgon Gas Development will be in accordance with Statement No. 800 (as amended by Statement No. 865). On 26 August 2009, the then Commonwealth Minister for the Environment, Heritage and the Arts issued approval for the Revised and Expanded Gorgon Gas Development (EPBC Reference: 2008/4178) and varied the conditions for the initial Gorgon Gas Development (EPBC Reference: 2003/1294).Since the Revised and Expanded Gorgon Gas Development was approved, further minor changes have also been made and/or approved to the Gorgon Gas Page 12 Public Chevron Australia Pty Ltd Uncontrolled when Printed Printed Date: 16 May 2014

10 Document No: G1-PP-QRT-GDL-0001 Barrow Island Quarantine: Development and are now also part of the Development. Further changes may also be made/approved in the future. This QMS relates to any such changes, and where necessary will be specifically revised to address the impacts of those changes. Use of an additional 32 ha of uncleared land for the Gorgon Gas Development Additional Construction, Laydown, and Operations Support Area (Additional Support Area) was approved by the Western Australian State Minister for Environment on 2 April 2014 by way of Ministerial Implementation Statement No. 965 and by Variation issued by the Commonwealth Minister for the Environment. Statement No. 965 applies the conditions of Statement No.800 to the Additional Support Area and requires all implementation, management, monitoring, compliance assessment and reporting, environmental performance reporting, protocol setting and record keeping requirements applicable to the Additional Support Area under Statement No.800 to be carried out on a joint basis with the Gorgon Gas Development. The Jansz Feed Gas Pipeline was assessed via Environmental Impact Statement/Assessment on Referral Information (ARI) and EPBC Referral assessment processes (Mobil Australia 2005, 2006). The Jansz Feed Gas Pipeline was approved by the Western Australian State Minister for the Environment on 28 May 2008 by way of Ministerial Implementation Statement No. 769 (Statement No. 769) and the Commonwealth Minister for the Environment and Water Resources on 22 March 2006 (EPBC Reference: 2005/2184). This QMS covers the Gorgon Gas Development as approved under Statement No. 800, and as approved by EPBC Reference: 2003/1294 and EPBC Reference: 2008/4178, and including the Additional Support Area as approved by Statement No. 965 and as varied by the Commonwealth Minister for the Environment. In addition, this QMS covers the Jansz Feed Gas Pipeline as approved by Ministerial Implementation Statement No. 769 and EPBC Reference: 2005/2184. In respect of the Carbon Dioxide Seismic Baseline Survey Works Program, which comprises the only works approved under Statement No. 748 before it was superseded, and under EPBC Reference: 2003/1294 before the Minister approved a variation to it on 26 August 2009, note that under Condition 1A.1 of Statement No. 800 and Condition 1.4 of EPBC Reference: 2003/1294 and 2008/4178 this Program is authorised to continue for six months subject to the existing approved plans, reports, programs and systems for the Program, and the works under that Program are not the subject of this QMS. 1.6 Purpose of this Quarantine Management System Legislative Requirements State Ministerial Conditions This QMS is required under Condition 10.1 of Statement No. 800, which is quoted below: Prior to commencement of construction of any terrestrial facilities listed in Condition 6.3 and the marine facilities listed in Condition 14.3, the Proponent shall submit the Quarantine Management System (QMS) to the Minister, taking into account the advice of the Quarantine Expert Panel (QEP) that meets the aim and objectives set out in Condition 10.3 and the requirements of Condition 10.4, as determined by the Minister, unless otherwise allowed in Condition 10.2 This QMS is also required under Condition 10.1 of Statement No. 769; i.e. Prior to commencement of construction of any terrestrial facilities listed in Condition 6.3 and the marine facilities listed in Condition 12.3, the Proponent shall submit the QMS to the Minister, taking into account the advice of the QEP that meets the aim and objectives set out in Condition 10.3 and the requirements of Condition 10.4, as determined by the Minister, unless otherwise allowed in Condition Chevron Australia Pty Ltd Public Page 13 Printed Date: 16 May 2014 Uncontrolled when Printed

11 Barrow Island Quarantine: Document No.: G1-PP-QRT-GDL Commonwealth Ministerial Conditions This QMS satisfies Condition 8.1 of EPBC Reference: 2003/1294 and Condition 8.1 of EPBC Reference: 2008/4178, which is quoted below: Prior to commencement of construction of any terrestrial facilities listed in Condition 5.2 and the marine facilities listed in Condition 11.3, the person taking the action must submit the Quarantine Management System (QMS) to the Minister, for approval, taking into account the advice of the Quarantine Expert Panel (QEP) established under the Western Australian Minister s approval for the action, unless otherwise allowed in Condition Objectives The objective of this QMS, as stated in Condition 10.3 of Statement No. 800, Condition 10.3 of Statement No. 769, and Condition 8.3 of EPBC Reference: 2003/1294 and 2008/4178, is that the Proponent shall not introduce or proliferate Non-indigenous Terrestrial Species and Marine Pests to or within Barrow Island or the waters surrounding Barrow Island, as a consequence of the Proposal. The specific objectives of the QMS are to: prevent the introduction of Non-indigenous Terrestrial Species and Marine Pests detect Non-indigenous Terrestrial Species (including weed introduction and/or proliferation) and Marine Pests control and, unless otherwise determined by the Minister, eradicate detected Nonindigenous Terrestrial Species (including weeds) and Marine Pests mitigate adverse impacts of any control and eradication actions on indigenous species taken against detected Non-indigenous Terrestrial Species (including weeds) and Marine Pests Requirements The requirements of this QMS, as stated in Condition 10 of Statement No. 800, Condition 10 of Statement No. 769, and Condition 8 of EPBC Reference: 2003/1294 and 2005/2184, are listed in Appendix Scope The QMS governs all materials, personnel, vessels, and aircraft travelling to Barrow Island, the smaller surrounding islands, and surrounding waters. The QMS also ensures that quarantine is integrated into the initial planning of all projects on Barrow Island, the smaller surrounding islands, and surrounding waters. Any matter specified in the QMS is relevant to the Gorgon Gas Development or Jansz Feed Gas Pipeline only if that matter relates to the specific activities or facilities associated with that particular development Hierarchy of Documentation This QMS will be implemented for the Gorgon Gas Development and the Jansz Feed Gas Pipeline via the Chevron Australasia Business Unit (ABU) Operational Excellence Management System (OEMS). The OEMS is the standardised approach that applies across the ABU to continuously improve the management of safety, health, environment, reliability, and efficiency to achieve world-class performance. Implementation of the OEMS enables the Chevron ABU to integrate its Operational Excellence (OE) objectives, processes, procedures, values, and behaviours into the daily operations of Chevron Australia personnel and contractors working under Chevron Australia s supervision. The OEMS is designed to be consistent with and, in some respects, go beyond ISO 14001:2004 Page 14 Public Chevron Australia Pty Ltd Uncontrolled when Printed Printed Date: 16 May 2014

Identify threats Management review, change Policy Quarantine barriers Continuous improvement Corrective action Objectives and targets Performance commitments Roles and responsibilities Monitor and audit Improvement program Communication Competency and training Figure 1-3 Flow Diagram of the Quarantine Management System The actions reflected in Figure 1-3 represent two distinct yet interrelated components, namely the core control components and the operational components. The core control components are: establish a policy for quarantine management, and set the direction for continuous improvement of the system. Implement the policy through improvement objectives, targets and action plans set objectives, targets, and the associated performance commitments undertake continuous improvement based on audits, lessons learnt, workplace assessments, and other industry benchmarks. The second group of activities relate to typical operational responsibilities, namely: define the management measures to be implemented to minimise quarantine risks develop quarantine barriers and incorporate these measures into designs, procedures, and specifications detailed in quarantine procedures; identify roles and responsibilities for personnel implementing management measures and ensure that these responsibilities have been clearly and effectively communicated ensure all personnel are trained and are competent to perform their tasks conduct measurement and verification to ensure the system represents best practice and demonstrates leadership in quarantine management. Perform monitoring, inspections, and audits to verify that management measures are being properly implemented and that they are effective engage in a regime of corrective action and continuous improvement. If monitoring, inspections, or audits show that improvement is required, the system should be self- Chevron Australia Pty Ltd Public Page 15 Printed Date: 16 May 2014 Uncontrolled when Printed

The system should also identify what actions need to be taken to improve performance and reduce risk incorporate a management of change process for identifying changes to operational activities or processes that could have an impact on quarantine, and for defining and implementing measures to minimise the quarantine risks associated with these changes. Figure 1-4 and Figure 1-5 provide an overview of the overall hierarchy of environmental management documentation within which this QMS exists. Further details on environmental management documentation for the Gorgon Gas Development and Jansz Feed Gas Pipeline are provided in Section 8.0 of this QMS.

16 Document No: G1-PP-QRT-GDL-0001 Barrow Island Quarantine: 1.7 Components of the QMS As part of the Chevron ABU, the Gorgon Gas Development and Jansz Feed Gas Pipeline is governed by the requirements of the ABU OEMS, within which a number of OE Processes exist. The Gorgon Gas Development and Jansz Feed Gas Pipeline will implement internally those OE Processes (and supporting OE Procedures) that apply to the Gorgon Gas Development and Jansz Feed Gas Pipeline s activities, where it is appropriate and reasonably practicable to do so. The key OE Processes taken into account during the development and subsequent revisions of this QMS, with a description of the intent of each Process, are: HES Risk Management Process Upstream and Gas (OE ; Chevron Australia 2012): The purpose of this process is to identify and address health, environment, and safety (HES) risks of facilities and activities related to the Gorgon Gas Development and Jansz Feed Gas Pipeline. Environmental Stewardship Process (OE ; Chevron Australia 2012a): This process applies during the operations phase of the Gorgon Gas Development and Jansz Feed Gas Pipeline. This process is designed to identify, assess, and manage potentially significant environmental impacts in a consistent manner and to continually improve environmental performance. A key business value objective is alignment with ISO (Standards Australia/Standards New Zealand 2004). Hazardous Communication Process (OE ; Chevron Australia 2012b): The purpose of this process is to establish the requirements for the communication of hazards associated with hazardous materials, and to eliminate or minimise the HES hazards associated with hazardous materials on ABU sites. Management of Change Process (OE ; Chevron Australia 2012c): This process focuses on ensuring an efficient and reliable process for implementing changes to organisational design, which includes the identification, control, and mitigation of OErelated incidents. Contractor Health, Environment, and Safety Management Process (CHESM) (OE ; Chevron Australia 2012d): The purpose of this process is to establish clear accountabilities, ensure active engagement of contractors, and provide a consistent CHESM program to eliminate HES incidents and injuries among contractors involved with the Gorgon Gas Development and Jansz Feed Gas Pipeline. Competency Development and Assurance Process (OE ; Chevron Australia 2012e): The purpose of this process is to provide a consistent and structured approach to building individual competency and overall organisational capability that will enable the ABU to achieve its business objectives. Incident Investigation and Reporting Process (OE ; Chevron Australia 2012f): The purpose of this process is to report and investigate incidents, including injury, operational, near miss, occupational illness, environmental (including quarantine), reliability, business disruption, and community concern. The lessons learnt can then be used to prevent future incidents. Emergency Management Process (OE ; Chevron Australia 2012g): This process provides the organisational structures, management processes, and tools necessary to respond to emergencies and to prevent or mitigate emergency and/or crisis situations. Compliance Assurance Process (OE ; Chevron Australia 2012h): This process addresses compliance with legal, internal and external safety, health, environment, reliability, and efficiency requirements.

17 Barrow Island Quarantine: Document No.: G1-PP-QRT-GDL Embedding the Quarantine Management System within OEMS Quarantine management is primarily a biodiversity strategy aimed at protecting the conservation values of Barrow Island and its surrounding waters. This is done by aligning all quarantine management measures with the applicable OE Processes and associated OE Expectations, which are arranged into OE Elements. OEMS has 47 OE Expectations organised within 13 OE Elements. OE Elements spell out specific requirements for the management of safety, health, environment, reliability, and efficiency. The expectations are met through processes and programs put in place by local business unit management (e.g. the Australasia Business Unit [ABU]). Of the 13 OE Elements, eight relate to and constitute the core of the Gorgon Gas Development QMS. These Elements, their respective QMS reference, and their goals are listed in Table 1-1. Table 1-1 OE Elements and their Goals OE Element Goal QMS Reference Environmental Stewardship Safe Operations Facilities Design and Construction Third-party Services Incident Investigation Emergency Management Management of Change Compliance Assurance Strive to continually improve environmental performance and reduce impacts from our operations Operate and maintain facilities to prevent injuries, illness, and incidents Design and construct facilities to prevent injury, illness, and incidents and to operate reliably, efficiently, and in an environmentally sound manner Systematically improve third-party service performance through conformance to Operational Excellence Investigate and identify root causes of incidents to reduce or eliminate systematic causes and to prevent future incidents Prevention is the first priority, but be prepared to respond immediately and effectively to all emergencies involving Chevron wholly owned or operated assets. For Chevron products of interests such as common carriers, chartered vessels, and facilities operated by others, be prepared to monitor the response and, if warranted, take appropriate actions Manage both permanent and temporary changes to prevent incidents Verify conformance with OE requirements in applicable Chevron Australia policy and Australian government laws and regulations. Train the workforce regarding their OE-related responsibilities Section 6.0 Section 8.2 Section 8.3 Section 8.4 Section 8.6 Section 8.7 Section 8.8 Section 9.0 The OE Elements and OE Processes relevant to quarantine management ensure that quarantine measures developed specifically for the Gorgon Gas Development and Jansz Feed Gas Pipeline remain aligned with the OE Vision, which is: To be recognised and admired by industry and the communities in which we operate as world-class in safety, health, environment, reliability and efficiency.

18 Document No: G1-PP-QRT-GDL-0001 Barrow Island Quarantine: 1.8 Stakeholder Consultation Development of the QMS Regular consultation with stakeholders was undertaken by Chevron Australia throughout the initial development of the environmental impact assessment management documentation for the Gorgon Gas Development and Jansz Feed Gas Pipeline. This stakeholder consultation included engagement with the community, government departments, industry operators, and contractors to Chevron Australia via planning workshops, risk assessments, meetings, teleconferences, and the PER, EIS/ERMP and Environmental Review (Chevron Australia 2013) formal approval processes. This document has been prepared with input from: The Quarantine Expert Panel (QEP): Members of the QEP reviewed this document and their comments have been incorporated or otherwise resolved. The QEP is required to provide advice on quarantine matters including the development and implementation of the QMS. The QEP has endorsed this QMS and its advice was provided in the document : Report provided to the Minister for Environment and Chevron Australia Pty Ltd on the Adequacy of the Development of the Gorgon Quarantine Management System (Quarantine Expert Panel 2009). The QEP contains subject matter experts from Western Australian Department of Parks and Wildlife (DPaW), Western Australian Department of Agriculture and Food (DAFWA), Western Australian Department of Fisheries (DoF), independent experts, and representatives of Chevron Australia. The Western Australian Department of Environment and Conservation (DEC) (now Department of Parks and Wildlife [DPaW]): Workshops and meetings were held involving the DEC and Chevron Australia personnel to discuss the scope and content of this QMS during its development. The DEC reviewed a draft revision of this QMS along with the feedback of the QEP. The DEC s comments have been incorporated or otherwise resolved. The Commonwealth Department of Environment, Water, Heritage and the Arts (DEWHA) (now Department of the Environment [DotE]): DEWHA reviewed and commented on a draft revision of this QMS along with the feedback of the QEP. DEWHA s comments have been incorporated or otherwise resolved Historical and Ongoing Consultation Overview of Historical Consultation Since 2003, substantial and continuous consultation has occurred throughout the process of developing the quarantine management measures for the Gorgon Gas Development and Jansz Feed Gas Pipeline. In EPA Bulletin 1221 (EPA 2006), the EPA recognised this:...the EPA is satisfied as to the expertise of the people involved in both making the risk estimates in workshops and providing guidance via an expert advisory panel convened by the proponent. The Bulletin went on to record:...this activity has involved a large amount of work by the proponent, its consultants and officers of a number of government agencies participating in public meetings, workshops and expert panel briefings. It was also recorded that during the initial development phase of the QMS, and consistent with the EPA s recommendation in Bulletin 1101 (EPA 2003):... the proponent organised a number of community and expert meetings and supporting processes to develop standards acceptable to the community and expert representatives for risks from introduced organisms. The process was transparent and Chevron Australia Pty Ltd Public Page 21 Printed Date: 16 May 2014 Uncontrolled when Printed

19 Barrow Island Quarantine: Document No.: G1-PP-QRT-GDL-0001 rigorous involving experts and community members to define acceptable levels of risk for the establishment of Non-indigenous Species on Barrow Island. This was reflected in the public submissions where one responder congratulated Chevron Australia on this process. The EPA believes that the process was credible and helpful in establishing a public view on acceptable risk Public Consultation Historical Chevron Australia convened five comprehensive community consultation meetings during 2004 and These meetings were widely advertised and well attended, independently chaired, and provided clear evidence of community input into the development of standards for acceptable risk, the process for developing quarantine barriers to meet acceptable risk standards, the approach for the development of the QMS, and reports of studies and surveys of interest to stakeholders. Interested stakeholders, each of which reported back to the wider community consultation meetings, also convened four special community workshops. These lengthy workshops enabled stakeholders to provide direct assistance in the development of standards for acceptable risk, and provided input on the content and structure of the QMS. Chevron Australia regularly responded to the requests of community groups and nongovernment organisations to discuss the status and progress of activities during development of the QMS. Records of QEP and Quarantine Advisory Committee (QAC) meetings, workshop reports, community consultation reports, and community workshop reports were all published on a publicly accessible website that was accessed thousands of times during the development of the QMS Subject Matter Expert Consultation Historical and Ongoing Since 2003, Chevron Australia has consulted with a large community of independent technical experts from government, scientific organisations, and independent specialists. The QEP was convened nine times between 2003 and 2005, and involved representatives of State and Commonwealth government departments, independent risk assessment specialists, and independent conservation and biosecurity specialists. Following submission of the Draft EIS/ERMP (Chevron Australia 2005), the QAC was convened six times between 2006 and 2008 to continue consultation with experts on the development of the QMS. The involvement of independent experts included activities such as the preparation of desktop and field surveys to address information gaps identified by the QEP and QAC. A new QEP was convened in 2008 under Chevron Australia s commitment for continuing expert consultation, as directed by Statement No This panel meets quarterly. From 2004 to 2006, 30 independent experts were involved in 33 risk assessment workshops for identifying quarantine threats and developing barriers that were judged to reduce the risk of introduction of a Non-indigenous terrestrial Species (NIS) or Marine Pest to acceptable levels. These experts contributed 133 days of independent advice and analysis (not including their preparation and follow-up efforts, which were often substantial). Further consultations with experts continue to improve the effectiveness of selected barriers and contribute to the review of the QMS, consistent with Chevron Australia s commitment to do so. Since 2009, ongoing consultation with independent experts concerning the detection program continues to validate and improve Chevron Australia s capability for detection early enough to enable eradication without substantial consequences to native flora and fauna. Chevron Australia has also attended a number of scientific workshops and symposia to present their methodologies and gain helpful advice. The Cooperative Research Centre convened these events for National Plant Biosecurity, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), the Australian Centre for Excellence in Risk Analysis, and DAFWA. Scientists from all over the world attended these events and the development of the QMS benefitted from their consultation.

20 Document No: G1-PP-QRT-GDL-0001 Barrow Island Quarantine: In addition, several studies relating to the QMS have been peer-reviewed and published in scientific journals. The methodology for risk assessments have been widely presented at national and international conferences. This exposure to the wider scientific community has resulted in the methods developed for the Gorgon Gas Development and Jansz Feed Gas Pipeline being adopted as a new benchmark for biosecurity efforts elsewhere DPaW, DAFWA, and DoF Consultation Historical and Ongoing DEC (now DPaW) and DAFWA representatives were present at all community meetings and workshops, and DoF representatives were invited to and attended many of these events. In addition, the DEC was an observer at all Quarantine Hazard Analysis (QHAZ) workshops, which also involved DAFWA and DoF technical experts. DEC and DAFWA participated as observers in the QEP and QAC meetings. Chevron Australia frequently consulted with DEC, DAFWA, and DoF technical specialists during the development of the QMS, particularly with regard to the technical feasibility of quarantine barriers, surveys, and desktop studies to address information gaps, and the design and operation of government surveillance programs. Two consultative meetings were held with DEC; the first held on 18 December 2007, on the progress of the Gorgon Gas Development QMS, and the second in February 2009 on the progress of the CO 2 Baseline Survey QMS. The latter can be considered as a trial for the Gorgon Gas Development QMS. Since 10 December 2008, members of the QEP were offered the opportunity to review or comment on any aspect of the proposed QMS. DPaW (formerly DEC), DAFWA, and DoF have representatives on this panel. This offer resulted in numerous QMS documents being requested and reviewed for the purpose of providing advice to the Western Australian Minister for Environment on the adequacy of the QMS. This consultation is continuous, via the QEP, and when the need arises these departments participate in discussions, with Chevron Australia, pertaining to the performance of the QMS. The process for development, review, and approval of this QMS is shown in Figure Commonwealth Consultation Historical and Ongoing The Commonwealth government nominated a representative to the QEP from 2003 to 2005 and provided helpful input and advice as an observer.

24 Document No: G1-PP-QRT-GDL-0001 Barrow Island Quarantine: Typical Gas Treatment Plant processes are described in Chapter 6 of the Draft EIS/ERMP (Chevron Australia 2005) Carbon Dioxide Injection System Reservoir carbon dioxide (CO 2 ) will be disposed of by injection into the Dupuy Formation more than 2000 m below Barrow Island to limit the greenhouse gas emissions and atmospheric pollutants associated with the Gorgon Gas Development and Jansz Feed Gas Pipeline s production of LNG. The CO 2 injection process is described in the Draft EIS/ERMP (Chevron Australia 2005). The CO 2 Injection System will consist of the mechanical components required to enable the injection of reservoir CO 2 and manage the performance integrity of the injection facilities and the Dupuy Formation. These include: CO 2 compression facilities located within the Gas Treatment Plant boundary an aboveground CO 2 pipeline (approximately 10 km long in an 8 ha easement) between the Gas Treatment Plant and the three CO 2 injection drill centres to the north nine CO 2 injection wells directionally drilled from the three CO 2 injection drill centres north of the Gas Treatment Plant site (Figure 1-2) observation wells for monitoring the subsurface spread of the CO 2 plume four pressure management water wells for managing pressure in the Dupuy Formation two pressure management water injection wells for the reinjection of water produced from the lower Dupuy formation by pressure management wells. The water will be reinjected into the Barrow Group from a vertical depth of 1200 to 1600 m shallow anode ground beds for the cathodic protection of all well types associated with the CO 2 Injection Project. Additional anode wells will be drilled for cathodic protection purposes for the pressure management wells and the pressure management water injection wells (one anode well pair for each water producer/injector pair). An anode well will also be required for each stand-alone observation well. Monitoring activities, including the acquisition of seismic data, will be undertaken as part of ongoing reservoir performance management. The total area occupied by the CO 2 Injection System outside the Gas Treatment Plant site will be approximately 12.5 ha Associated Terrestrial Infrastructure Terrestrial infrastructure associated with the Gorgon Gas Development consists of: the terrestrial component of the Barge (WAPET) Landing the Construction Village the Administration and Operations Complex the permanent Utilities Area located within the Gas Treatment Plant the Utilities Corridors between the Utilities Area and users within the Gas Treatment Plant and between the Utilities Area and the Construction Village, also servicing the Administration and Operations Complex road upgrades, including the road between WAPET Landing and Town Point, and from Town Point to the Airport (via the Construction Village), and road along the feed gas pipeline system route airport modifications, consisting of the extension of the existing runway to the south and associated vegetation clearing Chevron Australia Pty Ltd Public Page 27 Printed Date: 16 May 2014 Uncontrolled when Printed

25 Barrow Island Quarantine: Document No.: G1-PP-QRT-GDL-0001 communications, consisting of a microwave communications tower and associated communications infrastructure to be installed on Barrow Island onshore water supply infrastructure, consisting of a seawater demineralisation (reverse osmosis) plant, associated treated water and brine storage tanks, and treated water pumps and delivery piping to end users within the Gas Treatment Plant and utility corridors, reverse osmosis brine disposal pumps and the terrestrial component of the reverse osmosis brine pipeline Associated terrestrial infrastructure will be primarily located in the vicinity of, and south of, the Gas Treatment Plant site on the east coast of Barrow Island (Figure 2-1) Areas Impacted for Seismic Data Acquisition The expansion of the CO 2 plume injected into the Dupuy Formation below Barrow Island will be measured by comparing the reflection of vibrations through the subsurface. The terrestrial components of baseline seismic monitoring will use two vibration sources: subsurface explosives and vibroseis (Figure 2-1). Approximately 1300 shot holes will be drilled for the placement of subsurface explosives. These will be drilled at 100 m intervals along lines spaced 500 m apart. The placement of explosives below the surface karst limestone layer will be done by drilling the holes to a depth of approximately 15 m below sea level. Purpose-built drill rigs that combine both sonic and air percussion drilling technology will be used, reducing the need to use drilling fluids. The charges will be 4 kg each and double detonators will be used. Vibroseis consists of propagating energy signals into the earth from the surface via vibrator pads fitted to a truck. Vibroseis will be undertaken in the lower-lying, flatter terrain areas where good ground coupling is attainable and the effect on karst limestone is minimal. The vibroseis source lines will be spaced approximately 500 m apart, and the vibrator points will be every 12.5 m along these lines. Seismic data acquisition is expected to be repeated a number of times throughout the life of the Gorgon Gas Development, in order to map the extent of the CO 2 plume as it migrates. Differences between the data obtained during the baseline seismic monitoring and repeat seismic monitoring will be used to map the extent of the CO 2 plume over time Onshore Feed Gas Pipeline System and Terrestrial Component of the Shore Crossing (Gorgon and Jansz) The Onshore Feed Gas Pipeline System will traverse Barrow Island from the west coast at North Whites Beach to the Gas Treatment Plant site near Town Point on the east coast (Figure 2-1). The pipeline system will be approximately 14 km long and located within a right-of-way between 30 and 45 m wide. The pipelines will be buried with excavated material backfilled into the trench. The installation of the Onshore Feed Gas Pipeline System (including trenching, welding and pipe lowering) is expected to be completed at a rate of approximately 300 m to 350 m per day. The trench will be limited to approximately 2 km of open trench at any one time; however, the trench required for the pipeline systems (cables and tubes) will require the entire trench to be open for a relatively short period. The terrestrial component of the Shore Crossing will consist of infrastructure for drilling eight horizontally directionally drilled (HDD) holes from the shore to an exit point approximately 500 m offshore, and insertion of pipe strings into these holes. A ninth hole will be drilled for a seawater intake system, which will provide water required for the activities associated with drilling and pre-commissioning. The facilities required for construction of the Shore Crossing will include breakover supports and pipeline rollers for insertion of the pipelines. The HDD site will be approximately 80 m by 110 m.
