HSSE RISK CONTROL MANUAL

REINSTATEMENT AND REHABILITATION

Scope and Application This Manual describes QGC’s minimum mandatory requirements for the reinstatement and rehabilitation of disturbed areas, including Matters of National Environmental Significance (MNES) associated with QGC’s petroleum activities.

This Manual applies to all activities under QGC’s control. It applies to all QGC employees and contractors, including visitors to QGC workplaces.

This Manual belongs to a group of Risk Control Manuals designed to ensure compliance with regulatory requirements and minimise potential impacts to the Environment through defined controls and work standards. This Manual addresses the overarching system elements of managing environmental aspects of reinstatement and rehabilitation of assets. Site specific environmental aspects are identified and managed through the Upstream Delivery Process with reference to QGC’s ISO14001:2015 certified Environmental Management System.

Unless otherwise specified, the Business Unit manager is accountable for implementing this Manual.

In the event of discrepancy between this Manual and the Environmental Authority (EA) or Environment Protection & Biodiversity Conservation Act 1999 (EPBC) approval relevant to the work scope, the EA or Approval takes precedence if its conditions are more stringent, otherwise this document applies.

This Manual supersedes the QCLNG Gas Field Remediation, Rehabilitation, Recovery and Monitoring Plan (QCLNG-BX00-ENV-PLN-000026), Surat Basin Acreage Development Remediation, Rehabilitation, Recovery and Monitoring Plan (QCQGC-BX00-ENV-PLN-000015), QGC Gas Field Decommissioning Plan (QCLNG-BX00-ENV-PLN-000120), QGC Rehabilitation Framework – Overview (QCOPS-BX00-ENV-PLN-000003) and QCLNG Export Pipeline – Narrow Crossing Environmental Management Action Plan - Rehabilitation (QCLNG-BG03-ENV-PLN-000007).

1.3 Asset and Physical Lifecycle The disturbance area associated with a QGC asset can comprise of multiple physical lifecycle statuses through the life of the asset, including:

▪ Asset Footprint – the active operational area;

▪ Reinstated Footprint – stabilised but may be re-disturbed;

▪ Rehabilitated Footprint – no further disturbance (except maintenance);

▪ Final Acceptance Criteria – satisfies Environmental Authority rehabilitation requirements

QGC proactively reduces the environmental risk associated with its assets, by:

▪ reinstating areas not required for day to day operations of the asset, these areas will still be subject to operational maintenance (e.g. woody vegetation or restricted matter management);

▪ progressively decommissioning and rehabilitating (or transferring to land or tenure holder) assets which are not required, with the ultimate goal to relinquish tenements and surrender Environmental Authorities;

▪ rehabilitating areas (outside of the operational maintenance zone) of operational assets within areas of significance which aids in reducing the area of ongoing impact and time period to final acceptance once the asset is decommissioned. Areas of significance include Matters of National Environmental Significance (MNES), Environmentally Sensitive Areas (ESAs); and Endangered, Vulnerable or Near Threatened species (EVNT).

The end points of the asset lifecycle are:

▪ Retained – asset handed over to landholder or overlapping tenure holder

▪ Relinquished – rehabilitation handed over to landholder

Refer to QCLNG-BX00-GEN-PCE-000006 Spatial Data Model and Data Capture Dictionary

1.3.1 Supporting Business Processes

The key business processes which support reinstatement and rehabilitation are:

▪ Business Planning;

▪ Upstream Delivery Process (UDP);

▪ Pre-Execution and Execution;

▪ Maintenance; and

▪ Closure.

QGC’s Geographic Information System (GIS) and ISO14001:2015 Certified Environment Management System (EMS) support the business processes throughout the life of the asset to ensure compliance with QGC, stakeholder and regulatory reinstatement and rehabilitation obligations. Business processes and how they interact with the EMS and GIS are described further in Section 4.0.

4.0 Planning and Procedures This section describes the business processes that support reinstatement and rehabilitation to ensure compliance with QGC and regulatory obligations.

Business units and/or Contractors are responsible for developing their own Plans and Procedures that outlines measures, controls, monitoring & records to ensure that performance criteria, and additional requirements listed below are met.

Figure 2 Business processes that support reinstatement and rehabilitation with key records of each.

4.1 Business Planning Proposed Capital and Asset projects are subject to a six phase (identify, assess, select, define, execute, operate), stage gated process which is assured by Subject Matter Experts (SMEs), called Technical Authorities (TAs), who ensure relevant regulatory, legal, stakeholder and business requirements are included. The assurance process is called the Discipline Controls and Assurance Framework.

Planning for ongoing construction and progressive decommissioning in the Gas Field are presented in the Plans of Operations, which are updated at a minimum every 5 years, refer to Table 7.

More detailed business planning occurs during the annual budgeting cycle. Field Development Plans, which include construction and decommissioning, may be updated due to business or stakeholder needs. Current infrastructure plans are stored in QGC’s Geographic Information System (GIS). Proposed Field Development Plans are reviewed and approved through the Upstream Delivery Process.

4.2 Upstream Delivery Process The Upstream Delivery Process (UDP) is QGC’s internal workflow system used to identify and address any constraints including MNES before progressing upstream construction and decommissioning scopes through to execution. All development or decommissioning of infrastructure must be approved through this process and receive a series of functional endorsements culminating in an approval document, the Access to Work (ATW).

The ATW will summarise the scope of works, site specific constraints from stakeholder engagement and site surveys from a multi-disciplinary team including environment (e.g. ecology, soil specialists or rehabilitation specialists), cultural heritage, landholder and civil representatives. Reference to relevant controls or requirements for identified constraints from State or Federal approvals, legislation & codes of practice, the Environmental Management System (i.e. Manuals, Management Plans, Procedures etc) and landholder agreements are included in the ATW.

4.2.1 Matters of National Environmental Significance

Matters of National Environmental Significance are managed via the following steps:

1. Avoiding direct and indirect adverse impacts on MNES;

QGC applies the Field Developmenet Protocol in the upstream delivery phase to identify potential impacts to MNES. The siting of new infrastructure prioritises avoiding these impacts, ensuring continued habitat connectivity and signficiantly mitigates MNES impact.

In the event impact to an MNES is not avoidable due to competing constraints QGC ground truths the impact through ecological surveys and captures the proposed impact to enable mitigation and rehabilitation (Steps 2 and 3).

QCQGC-BX00-ENV-PCE-000001 Surat Basin Acreage Constraints Planning and Field Development Protocol

2. Mitigating and managing direct and indirect impacts on MNES;

The Significant Species Management Plans (SSMPs) listed in Table 8 outline the specific measures to avoid and mitigate impacts to MNES listed species and ecosystems. This includes optimising habitat and profiting habitat connectivity.

The mitigations requirements for an impact to an MNES are extracted from the relevant SSMPs and included in the ATW for implementation as per section 4.4. .

▪ Managing and mitigating waste generation – Waste Manual (QCQGC-BX00-ENV-MAN-000003)

4.2.2 Assessment of Potential Contamination QGC uses a stepwise approach to identify potential for contamination, assess contamination and determine appropriate management options. Refer to Appendix F for the process flow used for potential land and surface water contamination. Key standards for assessments include those listed below. Table 10 also describes example soil and water assessment criteria from the key standards below which QGC may use. The specific assessment method and criteria are determined on a case by case basis by the SME based on site specific factors.

4.3 Pre-Execution After issue of ATW, a site specific environmental management plan or environmental control plan which outlines how environmental constraints within the scope will be addressed, is developed and approved.

4.4 Execution The Business Unit Manager is responsible for ensuring reinstatement or rehabilitation performance criteria are met through execution of reinstatement or rehabilitation scopes.

QGC construction Contract Holder delegates formally accept reinstatement or rehabilitation meets approved scope / control plan requirements through a documented completion process.

4.4.1 Ignition Source Management The mitigation of ignition of fire risk is a key element of QGC’s HSSE-SP Management System. Table 12 below outlines the specific procedures to manage fire risk in each element of the business. The HSSE-SP MS primary objective is the protection of life, asset and the environment.

The high level hierarchy of controls to mitigate fire risk include:

▪ Carry out hot work (any work that creates an ignition source, e.g. welding, burning, gas cutting, grinding and brazing) in area free of flammable materials

▪ Eliminate ignition sources by selecting alternative work methods or equipment; and

▪ Implement controls to avoid the existence of flammable materials and ignition sources during hot work.

4.5 Maintenance

4.5.1 Issue Capture

Asset owners are responsible for implementing a routine monitoring program to identify any reinstatement or rehabilitation issues as outlined in section 6.1.

Civil maintenance issues post reinstatement or rehabilitation are recorded and prioritised in Civil Maintenance Tracker. If works remain within the existing approved footprint, re-approval through the UDP is not required, however, a modified scoping and execution process is followed, to identify risks and implement appropriate controls.

For underperforming rehabilitated sites, other actions may also be required such as further seeding, tubestock planting, or vegetation maintenance, to promote the site towards FAC. The specific circumstances of each underperforming site will be reviewed by the relevant SME to determine the scope of any required maintenance works.

4.5.2 Rectification Rectification works are undertaken in accordance with QGC’s reinstatement and rehabilitation procedure to ensure performance criteria are met. Rectification works are completed by the Wells team unless the asset is still within Defect Liability Period (DLP). Assets within DLP are the responsibility of the original execution contractor.

4.5.3 Vegetation Maintenance Restricted and prohibited flora (weeds) are managed according to legislative and stakeholder requirements.

During operations, vegetation, particularly woody vegetation, is managed to enable safe access to and operation of the asset.

4.6 Closure

4.6.1 Asset Retained Areas that are no longer required for ongoing petroleum activities can be retained by the landholder or overlapping tenure holder. This is not available in ESA or MNES areas.

Refer to Civil Maintenance Tracker Refer to QCQGC-BX00-ENV-PCE-000011 Reinstatement & Rehabilitation Procedure Refer to QCQGC-BX00-ENV-MAN-000002 Biosecurity Manual Refer to QCQGC-BX00-ENV-PCE-000012 Vegetation Management Procedure

https://sww.qgcapps.shell.com/maintenanceissuetracker/Lists/civilmaintenanceissues/AllItems.aspx






The minimum requirements for asset retention by the landholder or overlapping tenure holder are:

▪ Asset is safe, stable and non-polluting when it is transferred;

▪ Any dam must be decommissioned to no longer accept inflow from petroleum activities; and

▪ Water contained in any dam must have suitable quality for the on-going use(s) by the landholder or overlapping tenure holder

Landholders are engaged and accept the asset disturbance through signing the Landowner/Landholder Statement form within the Rehabilitation report.

Overlapping tenure holders retain disturbance areas through the process defined in the Co-Development Agreement.

4.6.2 Rehabilitation Final Acceptance When rehabilitated areas have reached FAC, a suitably qualified ecologist surveys the area and produces a report which demonstrates the area has achieved the final acceptance criteria.

Landholders are engaged and accept the rehabilitation through signing the Landowner/Landholder Statement form and Rehabilitation Report under the Environment Protection Act 1994. If there are no further access requirements, a Deed of Termination and Release is signed by both the tenure holder and landholder to terminate the Conduct and Compensation Agreement.

FAC reports and landholder acceptance are provided to the State Government as part of the Final Rehabilitation Report.

Ultimately, QGC aims to relinquish its tenements and surrender Environmental Authorities.

Environmental Authority conditions relating to rehabilitation acceptance criteria continue to apply after the environmental authority has ended or ceased to have effect.

6.0 Performance Evaluation

6.1 Monitoring Documented monitoring of reinstated and rehabilitated sites is to be undertaken by personnel responsible for the asset in order to demonstrate performance criteria have been met as per the minimum frequency described in Table 14. Monitoring methods may be physical or using remote sensing e.g. drone or satellite. After initial stabilisation, the temporal scale for succession of plant communities towards final rehabilitation acceptance may be significant, particularly for woody vegetation communities, and therefore, intense monitoring is unnecessary.

Table 15 Minimum frequency of monitoring reinstated & rehabilitated sites

Significance Frequency Example Site Types

High Annual Rehabilitated MNES listed threatened species habitat and communities (for 3 years)

Watercourse crossings (≥S02)

Significant slope (>15%)

Moderate 2 yearly Pond batter reinstatement

Rehabilitated ESAs B, Of Concern Regional Ecosystems & Essential Habitat (for 4 years)

Reinstated Rights of Way (first two years only)

Normal 5 yearly All other reinstated or rehabilitated assets

Asset specific monitoring, including monitoring of other environmental or operational aspects such as asset integrity or releases, is described in relevant EMS documents. Specific monitoring requirements for significant species are listed in relevant Significant Species Management Plans.

6.2 Assurance QGC Environment Lead Rehabilitation will review a subset of reinstatement and rehabilitation activities to assure relevant controls are in place and performance criteria have been met.

Business unit specific assurance activities are described in relevant EMS documents and conducted by Contract Holders, Asset Owners and Field Environment Advisors.

6.3 Audits This Manual will be subject to QGC’s HSSE and ISO14001 Audit program. Reinstatement and rehabilitation activities may also be subject to external third party or regulator audit.






6.4 Nonconformity Reinstatement and rehabilitation not in accordance with the processes described in this Manual, or high risk performance criteria are recordable incidents that should be recorded and managed in Fountain Incident Management .

Non-conformance with low risk performance criteria or civil maintenance issues shall be recorded in Maintenance Issue Mobile Data Solution form, for actioning through the Civil Maintenance Tracker within timeframes described in Non-conformance, corrective action and preventative action procedure (QCOPS-OPS-ENV-PCE-000026) and summarised

Significantly disturbed Has the meaning in Schedule 12, section 4 of the Environment Protection Regulation 2008. Land is significantly disturbed if

1. Land is significantly disturbed if:

a) It is contaminated land; or

b) It has been disturbed and human intervention is needed to rehabilitate it

i. To a condition required under the relevant environmental authority; or

ii. If the environmental authority does not require the land to be rehabilitated to a particular condition – to the condition it was in immediately before the disturbance

2. Without limiting subsection (1)(b), land requires human intervention to rehabilitate it if:

a) The disturbance has made te more susceptible to erosion; or

b) The use capability or suitability of the land is diminished; or

c) The quality of water in a watercourse downstream of the land has been significantly reduced

3. If land is significantly disturbed land because it is contaminated land, it ceases to be significantly disturbed land if a suitability statement is issued for the land.

4. If land is significantly disturbed land under subsection (1)(b), it ceases to be significantly






disturbed land if the administering authority is satisfied the land has been rehabilitated;

a) To the condition it was in immediately before the disturbance; or

iii. To another condition decided by the administering authority

SME Subject Matter Expert. Meets definition of suitably qualified person under Environmental Authorities.

Stable Has the meaning in Schedule 5 of the Environment Protection Regulation 2008 and, for a site, means the rehabilitation and restoration of the site is enduring or permanent so that the site is unlikely to collapse, erode or subside.

https://www.shell.com.au/about-us/projects-and-locations/qgc/environment/environment-management/management-plans.html

The purpose of the Rehabilitation Manual is to outline rehabilitation objectives to comply with QGC and regulatory requirements. A key driver for this document is to ensure there is one overarching system which outlines how rehabilitation requirements are identified and applied that reflects operational processes and is easily implemented.

It is the central document which ties together all the relevant procedures/operational control documentation for managing rehabilitation.

The specific detail is captured within operational control documents which have specific audiences and purposes depending on the owner of the process. E.g. Ignition source management isn’t solely a rehabilitation driven process. Constraints protocol detail isn’t required for construction reinstatement owners.

The method and specification for MNES is covered in the procedure and specification however additional measures are also dependent on the MNES being impacted and are outlined in the SSMP.
