8 Pest and Weed Management Plan 1 Introduction 1.1 QCLNG and Gas Fields QGC (A BG-Group Company) is currently moving from the approval phase of the QCLNG Project to implementation phase with both Commonwealth and State Government approvals obtained in October 2010 (Appendix 1). The project comprises three main elements: The Coal Seam Gas (CSG) Fields; Gas Collection Header (GCH) and Export Pipeline (EP); and LNG facility on Curtis Island. The CSG Fields and GCH occur in the Southern Brigalow Belt Bioregion of Queensland between the towns of Tipton and Taroom. The LNG Plant is located on Curtis Island on the Central Queensland Coast immediately north of the City of Gladstone. The Export Pipeline links these two areas. The pipeline runs northeast from the western end of Barakula State Forest (north of Miles) through to the Central Queensland Coast. Only the CSG Field area is considered in this plan that encompasses an area of 468,000ha within the Surat Basin. The extent of the CSG Fields is shown in Appendix Approval Conditions Development approval conditions addressed by this report pertaining to the control of weeds and pests associated with the Gas Fields as set by existing Environmental Authority, the Coordinator General and Department of Sustainability, Environment, Water, Population and Communities (DSEWPC) are provided in Appendix Distribution and Intended Audience This document is intended to be distributed to all field managers, land liaison officers, field environmental officers and contractor supervisors. It will also be provided to the Coordinator General, Department of Employment, Economic Development and Innovation (DEEDI) and Department of Environment and Resource Management (DERM) for review and endorsement. A copy of this document, or condensed version, will also be made available to any potentially affected landholder upon request by that landholder. 8 of 100

11 Pest and Weed Management Plan 2 Weed and Pest Management Plan 2.1 Introduction The QGC Gas Fields cover a broad geographic area of 468,000ha (Appendix 2). Several weed and pest animal species occur throughout these tenements. As a local landholder and industry operator, QGC aims to support the regional community with the management of pests and weeds to minimise their spread and economic impacts. This Weed and Pest Management Plan provides operational guidance and an action plan for the prevention, control and eradication of pests and weeds within QGC s tenement areas. QGC s goal is to ensure that gas field development and operations do not increase the presence or distribution of pests and weeds within or outside the project area, and neighbouring landholders properties are not adversely impacted. A weed can be defined as any plant growing where it is not wanted. Most weeds are introduced, although they can also be native. Weeds cost Queensland an estimated $600 million annually and have significant impacts on primary industries and natural ecosystems, as well as human and animal health. Weeds have natural mechanisms that ensure their spread and ongoing distribution and survival, aided by wind and water, and movement with livestock and native animals. The movement and transport of people, machinery, vehicles and equipment is potentially a major source of weed spread. QGC operations have the potential to aid weed spread if not effectively managed. The following sections provide guidance in preventing the introduction of new weeds into previously unaffected areas by QGC operations, and the spread of weeds between QGC properties, surrounding properties and tenements. QGC takes an integrated approach to weed management which is based around the important elements of weed hygiene, prevention of infestations, arresting weed outbreaks using effective reporting and physical or chemical control procedures, documenting weed infestations and auditing management programs, and using effective rehabilitation and seeding operations to out-compete potential weed outbreaks. QGC has a long term view of weed management across its gas field footprint and supports managing weeds in collaboration and consultation with landholders, natural resource management bodies and the government. QGC s pest management program aims to control animal pest species already present, using acceptable methods as well as identify potential pest species, their likely distribution and methods to prevent their spread. QGC has a long term view of pest management across its gas field footprint and supports effective monitoring and control of pest outbreaks in collaboration and consultation with landholders, natural resource management bodies and the government. 11 of 100

12 Pest and Weed Management Plan 2.2 Scope This Pest and Weed Management Plan has been created to collate existing QGC procedures and management plans for pests and weeds into one management document and provide additional weed and pest management methods. This document satisfies the requirements of Conditions G14 to G16 of the Project Environmental Authority (EA) PEN issued by DERM and those of the Coordinator General, DSEWPC and EIS commitments (Appendix 1). It is expected that this document will meet the requirements of any EAs issued for the QCLNG Project. It applies to the Gas Field only. 3 Weeds 3.1 Relevant Legislation In Queensland, the Land Protection (Pest and Stock Route Management) Act 2002 (LP Act) and the Land Protection (Pest and Stock Route Management) Regulation 2003 (LP Reg) are the relevant legislation regarding weeds. The LP Act and the LP Reg. provide legislative measures to manage pests and address the impacts they have on the economy, the environment and society. The DEEDI administers the pest provisions of the Act and its regulation. There are three classes of declared plants under the LP Act. These plants are targeted for control because they have, or could have, serious economic, environmental or social impacts. Class 1, 2 and 3 declared weeds that are likely to occur in the Gas Fields are listed in Appendix 3. Class 1 weeds are not commonly present in Queensland and, if introduced, would cause an adverse economic, environmental or social impact. Class 1 pests established in Queensland are subject to eradication from the state, if such a pest is sighted it must be reported to DEEDI. Class 2 pests are established in Queensland and have, or could have, an adverse economic, environmental or social impact. Landowners must take reasonable steps to keep their land free of Class 2 pest. Class 3 pests are well established in Queensland and have an adverse economic, environmental or social impact. Landowners are not required to control Class 3 pests unless the land is adjacent to an environmentally significant area. There are a number of environmentally significant areas in and around the QGC Gas Field tenements as shown in the QGC Gas Fields and Significant Areas map contained in Appendix 2. Under the Local Law provisions of the Local Government Act 1993, a local government can declare any plants not declared under the LP Act and enforce their control. Such plants are often referred to as environmental weeds as they can invade native ecosystems and adversely affect the survival of indigenous flora and fauna. For example, African Lovegrass, Eragrostris curvula, is not a declared weed, yet is undoubtedly a weed of concern for landholders in the region. Environmental weeds may have 12 of 100

13 Pest and Weed Management Plan significant economic and social impacts, as well as environmental impacts, including reduction of biodiversity, impacts on landscape, increased risk of fire and potential degradation of water quality. The Land Act 1994 also has provisions requiring control of weeds declared under the LPA on leasehold land. 3.2 General Weed Management, Hygiene and Monitoring Measures Preliminary Weed Identification Weed surveys of QGC tenements has been conducted and weed species abundance and distribution identified. Information from these preliminary surveys has been used in the production of this document. Pre-clearance surveys are, and will be undertaken across the QGC Gas Fields (mainly through Project Environmental Clearances) by Field Environment Officers (FEO) to identify and record the presence of weeds. This information will then be included into QGC s Constraint Planning and Field Development Protocol (the Protocol) Land Owner Consultations QGC representatives undertake consultations with landowners on a regular basis. Preliminary consultation forms such as the Property Evaluation Reports (PER) have been developed for land owner consultations and weed and pest distributions and management programs are covered in these reports. Information such as the presence of weeds, priority areas of concern for weeds on the property or neighbouring properties and requirements for vehicle wash-down prior to entering the property will be recorded. Information on distribution of weeds and concerns from landowner interviews are to be collated and integrated into QGC management plans and the Protocol to ensure weed data is captured spatially. Land-use issues such as Organic Certification and the effect on QGC chemical weed management programs will be discussed with Landowners. QGC will ensure any future weed management on the property does not impact on the property s Organic Certification Regional Council Consultations QGC will undertake on-going consultation with Western Downs, Maranoa and Banana Regional Councils on regional weed management plans and issues on a regular basis. Taroom Shire Council (now included in Banana Regional Council) adopted a Pest Management Plan in 2006, identifying high priority weed species including; Parthenium, Harrisia Cactus, Parkinsonia, African Lovegrass, Giant Rat s-tail Grass, Mother of Millions and African Box Thorn. The prevention of the spread of Parthenium to the south of its existing distribution was identified as a Very High priority by the Taroom Shire Council in their management plans. Therefore QGC have included these weeds as priority for management. Several of the regional Councils Pest Management Plans including Banana and Western Downs are under review therefore QGC commit to liaising with relevant council officers and incorporating any additional 13 of 100

14 Pest and Weed Management Plan requirements once these plans have been finalised. This Pest and Weed Management Plan will be reviewed at least annually and updated to address any local government issues of concern Stakeholder Organisations Consultations The Condamine Alliance and Queensland Murray-Darling Committee are two stakeholder organisations that work in the region of QGC s Gas Field tenements and have produced plans on weed and pest management for the area. Consultation with these and other stakeholder organisations will be conducted on a regular basis to discuss and identify priority areas of concern and weed management programs in relation to the integration of QGC management plans and what is occurring on a regional basis. For example the Parthenium Rapid Response Program and the National Lippia Management Strategy are being conducted in the region Weed Identification during Operations Ongoing weed surveys will be undertaken to identify the overall abundance and diversity of weed species across QGC tenements and adjacent lands. High risk weeds or areas will be noted and may be used to generate special conditions of access for gas field activities. All QGC contractors and staff will be trained in basic weed identification and encouraged to immediately report the location of weed sightings and provide a photo of the species to a FEO. All QGC vehicles will be issued with a weed identification booklet to assist staff identify weeds during their daily duties. Such reports should be made using a QGC Hazard Observation (HAZOB) Booklet. All such records will be provided to a FEO, who then ensures it is incorporated into the QGC Weed Database (that is part of the overall QGC Protocol) to assist in tracking weeds and their distribution, identifying management requirements, assist in monitoring and determining the success of management, and reporting. The FEOs will then decide the most appropriate control method and delegate this task to the appropriate person. Only licensed Chemcert operators can spray weeds as there are health and safety risks associated with the use of weed control chemicals. A list of QGC Chemcert licensed operators can be obtained from the FEO or the field technical assistants. Landowners will be consulted prior to chemical control methods being applied Operational Control Procedures A number of operational activities in the gas exploration and production field increase the risk of weeds being spread within the tenements and outside the Project area. Key activities to be managed include: Movement of people, vehicles and machinery Clearing vegetation Movement of soil and vegetation 14 of 100

15 Pest and Weed Management Plan Management and control procedures which must be implemented when undertaking activities that involve these threats are described below. Pegging Parties Pegging parties require QGC vehicles to drive onto private properties and people to walk across a property that may either be weed free or have weed infestations. The following steps should be taken during pegging parties: During the initial contact between the Land Access Officers and the Landholder, weed issues should be discussed, including any existing weed management programs or presence of weeds on the property. QGC weed management strategies should be conveyed to the landholder and any landholder requests or concerns passed onto the pegging party. This information will then be used to develop the rules for land access and incorporated into the QGC Weed Database. Minimise the number of vehicles taken by the pegging party onto any property. Vehicles are to stay on designated tracks and avoid driving through long grass and weed infestations. Vehicles must not have been exposed to any significant risk of re-contamination between cleandown and entry to a new property. Such events should be cause for an additional decontamination clean-down and obtain certification. During the pegging party, the FEO should take note of and record any weed infestations. Photos and GPS locations of any weeds shall be recorded by the FEO on an approved QGC form. This information will then go into the QGC Weed Database and Protocol. If there are significant weeds or infestations noted on the property during the pegging party QGC vehicles should be cleaned down before re-entering other properties or tenements. Any weed issues or requirements reported by the FEO will be passed on to relevant construction staff with key recommendations for their management prior to any clearing or construction occurring on the property. Infrastructure Earthworks and Track Construction During the construction period the following steps must be taken: Earthmoving machinery must be cleaned down prior to entering the property if requested by the landholder or advised by a FEO. See Weed Hygiene for Vehicles and Machinery Guidelines section below. Earthmoving machinery must be cleaned down as soon as possible, either on site or at the closest clean-down facility, upon completion of works and leaving the property if advised by a FEO or operators notice the presence of weeds in the construction area. 15 of 100

16 Pest and Weed Management Plan If the construction area is located over a number of properties, the FEO will make a recommendation in the relevant site environmental approval if machinery will need to be cleaned down when moving between properties. Local Borrow Pits will be utilised in the construction of site infrastructure earthworks. Location of the Borrow Pits will consider weed dispersal issues. Topsoil from Borrow Pits will be stockpiled for use in site rehabilitation and any weeds controlled before transportation to other sites. Prior to importing bulk materials and products, including earthworks fill, QGC will confirm with suppliers the weed status of materials by requesting a written statement i.e. weed hygiene declaration form as per guidelines set out below. Drilling During drilling operations the following steps must be taken: Drilling rigs and associated vehicles and equipment will require clean-down if advised by a FEO, or if the contractor is aware the rig has been operating in a weed risk area. External contractors must provide the QGC Rig Drilling Supervisor with appropriate documentation to verify that vehicles and equipment have been cleaned before entering QGC leases. Pipeline Construction During survey mark-up, clear and grade, trenching and rehabilitation, the following steps must be taken: Site environmental clearances will follow the same procedure as for pegging parties. During the clear and grade, earthworks machinery and any vehicles entering the right of way must be cleaned prior to entering and upon completion of works. All machinery arriving at QGC s right of way for clear and grade must be accompanied by a weed free declaration and should be inspected by QGC FEOs prior to works commencing. Once clear and grade of the right of way is complete, Clean on Entry points (COE) will be established along the right of way. Marked by signs, these will be the only access points for machinery and vehicles during pipeline trenching and construction. Machinery and vehicles must use COE and as long as they do not leave the right of way, gravel roads or sealed roads and it has not rained, they will not require rewashing. COE will be located at points that intercept gravel or sealed roads so that minimal rewashing will be required. If a COE point is required away from gravel or sealed roads, the access track will be constructed in such a way that minimal rewashing will be required. Rehabilitation Works 16 of 100

17 Pest and Weed Management Plan Rehabilitation equipment will need to be cleaned down upon entry of right of way and upon completion of work. FEOs will ensure from suppliers in writing, materials imported for rehabilitation including; topsoil and seed stock are weed free. i.e. weed hygiene declaration form as per guidelines set out below. Machinery and equipment must be cleaned down before movements between gas fields as per the following guidelines through designated COE points. Operations All QGC vehicles should be cleaned on a regular basis. During day to day operational visits by Production Operators and other staff, vehicles will not require a clean-down as long as they do not leave sealed roads, gravel roads or well pads. The only exception to this is if a FEO recommends vehicles and equipment are to be cleaned upon leaving high risk areas. If a vehicle enters an area where it has recently received rain and is muddy, the vehicle should be cleaned as soon as possible. If a vehicle passes through a suspected weed infestation area, it is the driver s responsibility to ensure a clean-down is completed. For example, pulling onto the road verge to take a phone call might expose the vehicle to weeds such as lovegrass and mother of millions which are common in disturbance zones. Vehicle operators will be responsible for record keeping and are subject to audit Reporting and Mapping Following on-site weed identification and relevant consultations, weed location information in the form of GPS coordinates or site location descriptions are to be provided to QGC FEOs with the location and details of weeds to then be entered into a QGC Weed Database and Protocol. Records will also be kept of what management action may have been taken after the record was made. Weed mapping information will be developed from the database and used in the development of site specific weed management plans. Follow-up treatment, inspections and monitoring will be used to study the effectiveness of these plans. 3.3 Weed Hygiene for Vehicles and Machinery Guidelines QGC s Environmental Guideline Weed Hygiene for Vehicles and Machinery (OPS-T-GDL-0002 Rev B February 2011) has been prepared by QGC to include requirements outlined in the Petroleum Industry (including coal seam methane gas) Minimising Pest Spread Guidelines (PIMPSG) and Queensland checklist for Clean-down Procedures. 17 of 100

18 Pest and Weed Management Plan An overarching framework that outlines the main approach to when QGC vehicles or machinery should be cleaned and to what extent is provided in Appendix 4. This matrix is taken from the Petroleum Industry (including coal seam methane gas) Minimising Pest Spread Guidelines General Vehicle Measures to Minimise Weed Spread The following general measures should be applied by all staff and contractors to minimise weed spread: Vehicles to avoid leaving designated access tracks or roads; Vehicles, machinery and equipment suspected of carrying weed seed will be cleaned following the recommendations listed below; Project-specific weed management recommendations will be identified in each project s Construction Environmental Management Plan and the project specific Land Access Rules Overview; QGC fleet vehicles must be thoroughly washed once per week and interiors thoroughly cleaned once per month; Each QGC or contractor vehicle must have a current Weed Inspection Report or weed declaration when arriving on QGC land or leaving QGC private property for work purposes; Ensure clothing and footwear are free of mud and seeds before stepping in vehicles; Work in clean areas first or start in areas with the least amount of infestation during peak seed production times; Secure loads that are suspected to contain weed seeds; QGC field staff and contractors to receive basic weed identification training and be issued with a weed booklet; Contact the Environment Team for any enquiries or for reporting of weed sightings; Report weed sightings to FEO, record in QGC GIS Database and incorporate into QGC Protocol Cleaning of Vehicles and Machinery Clean-down requirements and procedures are detailed in QGC s Environmental Guideline Weed Hygiene for Vehicles and Machinery (OPS-T-GDL-0002 Rev B February 2011). It is the responsibility of every contractor/employee to keep their vehicles and machinery weed free. This includes regularly checking and cleaning the vehicle, in particular when driving off-road. QGC employees using a fleet vehicle are expected to wash their car once per week and clean the interior monthly. This is the minimum requirement. 18 of 100

19 Pest and Weed Management Plan QGC s Environmental Guideline (OPS-T-GDL-0002 Rev B February 2011) indicates that two forms are to be used as part of the Weed Hygiene Procedures: - the Weed Hygiene Declaration Form issued by the Queensland Government; and the QGC Internal Weed Hygiene Inspection Report. The Weed Hygiene Declaration Form should generally be used every time a thing such as a vehicle or other piece of machinery is transported to a new area or property and on request and is further explained in Section The QGC Internal Weed Hygiene Inspection Report serves as a supplement form that should be used as a means of good company practice as it lists individual cleaned items and can only be signed by a competent inspector. The weed hygiene inspection report should be used to manage land holder specific weed free requests. The location of QGC clean-down facilities will be determined in the operational planning phase for each field based on results of pre-clearance surveys, pegging parties, confirmation of the location of infrastructure and consultation with landowners. Currently numerous local community clean-down facilities are located within the Gas Field region and are listed in Table 1.

20 Pest and Weed Management Plan Weed Hygiene Declaration Under the LP Act, it is an offence to supply a thing that is contaminated with a Class 1 or Class 2 weed. For Class 2 weeds, however, there is an exemption: A person does not breach the Act if they provide a written notice that states that the thing is or may be contaminated with a Class 2 weed and hands out this written notice to the receiver before the thing is supplied. Written notice in the sense of the Act is the Weed Hygiene Declaration (Appendix 5). This notice has to be filled out by the supplier prior to entering the property and contains information about the type of equipment that is supplied or transported and its contamination status. Machinery, such as vehicles, is considered clean when no soil or organic matter that may contain weeds or weed seeds is attached to the machinery. The Weed Hygiene Declaration provides information on two separate activities, Part 1- Sale or supply of things and Part 2 - Transport of contaminated things. Part 1 should be completed if a new vehicle is transported to a sensitive area or the purchase of materials (organic matter) requires proof of weed free supply for example in rehabilitation or earthworks operations. Weed Hygiene Declarations are to be kept by both the supplier and receiver for five years for these activities. Part 2 should be completed when machinery or persons are moving from location to location or in QGC case, property to property. If the things is deemed to be contaminated, the receiver can either refuse the thing or take precautions to prevent new weed infestations. Failure to supply a written notice can incur a penalty of up to $ Weed Hygiene Inspection Report QGC provides a company internal Weed Hygiene Inspection Report as a supplement to the Weed Hygiene Declaration Form (Appendix 6). The Weed Hygiene Inspection Report itemises the cleaned and inspected locations in detail and gives comprehensive information about the vehicle/machinery. It is recommended because it ensures proof of process and due diligence in the weed management procedure. The form provides evidence for future reference should a situation relating to the spread of weeds arise to acknowledge the steps taken on weed control (QGC Environmental Guideline: Weed Hygiene for Vehicles and Machinery. OPS-T-GDL-00002, Rev B February 2011). The Hygiene Inspection Report can only be signed by an inspector who has been trained and deemed competent by successfully completing the courses RTD2312A and RTD2313A provided by Greening Australia and other organisations. Authorised Vehicle Inspectors can be QGC or third party contractors. Third party certifications are currently conducted under certain circumstances such as cases where landholders raise significant concerns. The following table provides information on authorised third party weed inspectors current at the time of report preparation (Table 2).

QGC dams will be monitored to ensure there is no translocation of aquatic weeds associated with water releases. 4 Pests 4.1 Relevant Legislation In Queensland, the Land Protection (Pest and Stock Route Management) Act 2002 (LP Act) is the relevant legislation regarding animal pests. The LP Act and the Land Protection (Pest and Stock Route Management) Regulation 2003 (LP Reg.) provide legislative measures to manage pests and address the impacts they have on the economy, the environment and society. The Department of Employment, Economic Development and Innovation (DEEDI) administers the pest provisions of the Act and its regulation. There are three classes of declared animals under the Land Protection (Pest and Stock Route Management) Act These animals are targeted for control because they have, or could have, serious economic, environmental or social impacts. Class 1, 2 and 3 declared animals are listed in Appendix 8. Class 1 pests are not commonly present in Queensland and, if introduced, would cause an adverse economic, environmental or social impact. Class 1 pests established in Queensland are subject to eradication from the state; if such a pest is sighted it must be reported to the DEEDI. Class 2 pests are established in Queensland and have, or could have, an adverse economic, environmental or social impact. Landowners must take reasonable steps to keep their land free of Class 2 pest. Class 3 pests are well established in Queensland and have an adverse economic, environmental or social impact. Landowners are not required to control Class 3 pests unless the land is adjacent to an environmentally significant area. There are a number of environmentally significant areas in and around the QGC Gas Field tenements as shown in the QGC Gas Fields and Environmentally Significant Areas map contained in Appendix 2. Under the Local Law provisions of the Local Government Act 1993, a local government can declare any animals not declared under the LP Act and enforce their control. For example, Eastern Grey Kangaroo, Macropus giganteus, is not a declared pest, yet is a perceived pest when in overabundance. Nondeclared animals of concern when in excessive numbers may have significant economic and social 35 of 100

36 Pest and Weed Management Plan impacts by competing for food or destroying crops, as well as environmental impacts, including reduction of biodiversity, impacts on the landscape and degradation of water quality. The DEEDI recommends control and reporting on non-declared pest animals. Management of these pests requires coordination and they are subject to programs led by regional government, industry and/or landowners. In Queensland, the Fisheries Act 1994 (Fisheries Act) is the relevant legislation regarding noxious fish pests. The Fisheries Act provides legislative measures to manage pest fish and address the impacts they have on the economy, the environment and society. The DEEDI administers the noxious pest provisions of the Act and its regulation. In line with the federal government, under the Fisheries Act 1994 the state government can declare any fish that is or may become a pest to native aquatic communities. For example, European, Mirror and Koi Carp, Cyprinus carpio, is a declared noxious fish and may not be kept, sold or brought into the state and may not be released or used as bait in Queensland waters. Landowners (including QGC) are required to control any possible release of noxious fish from their impoundments. 4.2 General Pest and Waste Management and Monitoring Measures Preliminary Pest Identification Preliminary pest surveys may be undertaken, usually in conjunction with vegetation surveys, to identify the abundance and distribution of pest species across QGC tenements and adjacent lands. Preclearance surveys are also being undertaken across the QGC Gas Fields (mainly through Project Environmental Clearances) by Field Environment Officers (FEO) that identify and record the presence of feral animals. This information will then be included into QGC s Constraint Planning and Field Development Protocol (the Protocol). Incidental identification of pest distribution such as signs of feral pig activity may be discovered during these preliminary surveys. High abundance and distribution of pest species will be noted and may be used to generate special conditions of access or controls for gas field activities. A survey of QGC owned tenements has been conducted and incidental identification of pest activities has been recorded. Information from these surveys has been accounted for in this document Land Owner/Manager Consultations QGC representatives undertake consultations with landowners on a regular basis. Preliminary consultation forms such as the Property Evaluation Reports (PER) have been developed for land owner consultations and weed and pest distributions and management programs are covered in these reports. Information such as the presence of feral animals on the property or neighbouring properties and any feral animal management programs in place will be recorded. Information on distribution of feral animals 36 of 100

37 Pest and Weed Management Plan and control programs are to be collated and integrated into QGC management plans and the Protocol to ensure feral animal data is captured spatially Regional Councils Consultation with Western Downs, Maranoa and Banana Regional Councils will be conducted in regards to regional pest management plans and areas of concern regarding these issues. Taroom Shire Council (now included in Banana Regional Council) adopted a Pest Management Plan in 2006, identifying high priority pest species including; Locusts, Wild Dogs/Dingoes and Feral Pigs. The programs included maintaining baiting provisions, coordinating landholder baiting programs and public awareness exercises. QGC will work with local governments in the implementation of feral animal control programs where they are the landowner or it is an area directly impacted by QGC operations Stakeholder Organisations Consultations The Condamine Alliance and Queensland Murray-Darling Committee are two stakeholder organisations that work in the region of QGC s Gas Field tenements and have produced plans on weed and pest management for the area. Consultation with these and other stakeholder organisations are to be conducted on a regular basis to discuss and identify priority areas of concern and pest management programs in relation to integrating QGC management plans Pest Identification during Operations The overall abundance and diversity of pest species across QGC tenements and adjacent lands will be identify during field surveys. High risk pests or areas will be noted and may be used to generate special conditions of control during gas field activities. QGC infrastructure is audited by the Environmental Team annually and additional follow-up field surveys will be conducted at this time. All QGC contractors and staff are encouraged to immediately report the location of pest sightings and provide a photo where possible of the species to a FEO. Such reports should be made using a QGC Hazard Observation (HAZOB) Booklet. The FEOs will then liaise with the relevant local government pest officer and decide the most appropriate control method or program. Only certified operators can be used to control pest infestations and they are most effective when undertaken across properties (rather than one property at a time). Landowners will be notified prior to any pest animal control being undertaken Accommodation Camp Waste Management The risk of increased pest species populations due to accommodation camps in the Gas Fields is significant. To control the associated risks with large accommodation camps, waste management procedures will be produced and monitoring of camp environs for pest species will be conducted. Procedures will predominately focus on reducing the amount and access to food waste by pest species. Wild dog, feral pig, fox and vermin pest species populations will be monitored near the camps and results 37 of 100

38 Pest and Weed Management Plan collated to allow development of control programs for these species. Control of pest species will be in accordance with waste management guidelines and where possible integrated with other programs in the region Reporting and Mapping Following on-site pest identification and relevant consultations, pest location information in the form of GPS coordinates or site location descriptions are to be provided to QGC FEOs with the location and details of the pest to then be entered into the QGC Protocol. Records will also be kept of what management action may have been taken after the record was made. Pest animal mapping information will be developed from the database and used to assist in decision making. Follow-up treatment, inspections and monitoring will be used to study the effectiveness of these plans. 4.3 Pest Species Recorded or with Potential to Occur in the Gas Fields Pest animal species recorded or with potential to occur in the Gas Fields are listed in Table 4. These form pests of concern for the Gas Fields and subject to management as detailed in this report.

These measures have drawn largely on information provided by Primary Industries and Fisheries section of DEEDI Management of Rabbits Plate 27: Rabbit Plate 28: Rabbits Rabbits are a highly destructive pest that cost the Australian economy between $600m-$1b per year. Rabbits are regularly sighted on QGC properties, and have been increasing in numbers leading to 39 of 100

40 Pest and Weed Management Plan pasture degradation on not only QGC land but also neighbouring properties. The most effective solution for rabbit control as prescribed in the Rabbit Control in Queensland handbook, published by the former DPI&F Queensland (now DEEDI), is the destruction of warrens with machinery and then as a mop up, the controlled shooting of the remaining animals. The destroyed warren or refuge areas should then be fenced off. These techniques, if carried out properly, should lead to a long term control of the rabbit population, in the area, especially if carried out in conjunction with neighbouring land owners. Consultations in regards to the Darling Downs-Moreton Rabbit Board Fence have been conducted and are continuing between QGC and DEEDI. A Rabbit distribution map produced by Biosecurity Queensland, is provided in Appendix 9. QGC will participate in any Rabbit control programs that may be coordinated by local government or other stakeholder in consultation with affected landowners. QGC Gas Field distribution maps will be produced as field distribution data is continually collated Management of Wild Dogs and Dingoes Plate 29: Dingo behind fence Plate 30: Dingo There are several techniques for the management of wild dogs mentioned by the DEEDI including the use of pesticides in bait, trapping, exclusion fencing, shooting and guard animals (DEEDI July 2010a). Wild dogs and dingoes are not currently considered a significant threat on QGC tenements. However state government statistics show the number of wild dogs is growing rapidly in the area and is becoming more of an issue. The DEEDI considers shooting by professionals to be of low concern in regard to animal welfare and is considered an appropriate control method. QGC will be taking part in a Dalby Regional Council initiated Feral Dog Baiting Program. QGC will engage in consultation with Biosecurity Queensland in regards to future baiting programs. 40 of 100

41 Pest and Weed Management Plan Consultations in regards to the Wild Dog Barrier Fence have been conducted and are continuing between QGC and DEEDI. A Wild Dog distribution map produced by Biosecurity Queensland, is provided in Appendix 9. QGC Gas Field distribution maps will be produced as field distribution data is continually collated Management of Feral Pigs Plate 31: Feral Pig Plate 32: Feral Pigs in Trap Feral Pigs are difficult to control for a number of reasons as outlined by the DEEDI fact sheet on control of feral pigs (DEEDI July 2010b). The recommended strategy for the control of pigs is trapping, and whilst this is time consuming it is acknowledged to be the best solution in terms of welfare and control available. The traps can be made with pig specific triggers that ensure that other local fauna is not affected. QGC will engage in consultation with Biosecurity Queensland and other stakeholders in regards to any future Feral Pig baiting programs. A Feral Pig distribution map produced by Biosecurity Queensland, is provided in Appendix 9. QGC Gas Field distribution maps will be produced as field distribution data is continually collated. 41 of 100

42 Pest and Weed Management Plan Management of Foxes Plate 33: Fox in Log Plate 34: Fox stalking Chickens Foxes are a prominent pest in the area of the QGC Gas Field tenements and their population is increasing. The control of foxes should suit individual circumstances. In some instances it may be desirable for foxes to remain because of their ability to control other pests. Options for the control of the fox include poisoning, trapping, shooting, guard animals and exclusion fencing (DEEDI July 2010c). A Fox distribution map produced by Biosecurity Queensland, is provided in Appendix 9. QGC Gas Field distribution maps will be produced as field distribution data is continually collated Management of Macropods Plate 35: Kangaroo Plate 36: Kangaroos The macropods commonly found on QGC Gas Field tenements are the Eastern Grey Kangaroo and Red Necked Wallaby. The macropod population is viewed as a threat to agricultural production. Should a field 42 of 100

43 Pest and Weed Management Plan survey indicate that control is required; the best form of control for the macropod population is by selective culling performed by a professional hunter with the required licenses. Given these macropods are native species, control programs conducted by QGC will be carefully planned and fully justified, and must be done so in consultation with the Regional Council and local community. 43 of 100

44 Pest and Weed Management Plan Management of other Pest Species Plate 37: Mouse Plate 38: Mouse Plague - Dalby Other pest species, including feral goats, feral cats, cane toads and mice are not perceived to be a significant threat to any of QGC s Gas Field tenements however they are active in the area. As such they will be managed within regulations on a case by case basis. Staff and contractors are encouraged to report any sightings of these species. Project environs including equipment, materials and ponded water will be monitored for mosquito breeding grounds and any equipment or debris no longer required will be disposed of Aquatic Pest Species Plate 39: European Carp Plate 40: Mosquitofish- Female Aquatic pest species, including European Carp (Cyprinus carpio) and Mosquitofish (Gambusia holbrooki) are declared noxious pests species in Queensland. European Carp are present in the Condamine- Balonne catchment and Mosquitofish are widespread throughout Australia. As such they will be managed within regulations on a case by case basis. Prevention of infestation and multidisciplinary control methods are the best way to control the spread of aquatic pests in the gas field region. Care must be taken around any water impoundments and water releases from these bodies in regards to the possible translocation of pest species. 44 of 100

45 Pest and Weed Management Plan Waterways and impoundments of the Gas Fields will be monitored for possible infestations of noxious pests. Staff and contractors are encouraged to report any sightings of these species. 5 Monitoring and Review 5.1 Roles and Responsibilities All QGC contractors and staff will be trained in basic weed and pest identification and encouraged to immediately report the location of these sightings, with a photo of the species where possible, to a FEO. All QGC vehicles will be issued with a weed identification booklet to allow all staff to identify weeds during their daily duties. Such reports should be made using a QGC Hazard Observation (HAZOB) Booklet. The FEOs will then decide the control method most appropriate and delegate this task to the appropriate person. Only licensed Chemcert operators can spray weeds as there are health and safety risks associated with the use of weed control chemicals. A list of Chemcert licensed operators can be obtained from the FEO or the field technical assistants. Personnel responsibilities in regards to identification, monitoring and collation of weed and pest species are listed in Table 5. Table 5: Identification, Monitoring and Collation Responsibilities for Weed and Pest Species Role Responsibility Field Environmental Officer or Site Ecologist Inspect sites for weeds and pests during pegging parties Ensure risk classification is provided in the clearance report Provide guidance and direction for vehicle/machinery clean-downs Receive identification reports of weeds and pests and enter into QGC database Determine appropriate management actions after identification is made Provide guidance and direction to QGC staff and contractors in relation to weed and pest requirements Construction and Project Supervisors Chemical Application Operators Ensure weed control requirements are communicated to contractors and enforced. Inspect vehicles and machinery as necessary. Conduct weed control measures as directed and maintain records. 45 of 100

46 Pest and Weed Management Plan Drilling Superintendents All Staff and Contractors Weed Hygiene Inspection Officers Ensure weed control requirements are communicated to contractors and enforced. Inspect vehicles and machinery as necessary. Complete clean-downs as required and submit vehicles, machinery and equipment for inspection. Identify and report weeds and pests using HAZOB booklet. Conduct Weed Hygiene Inspections and issue Weed Hygiene Inspection Report. 5.2 Data Management Field information in the form of preliminary surveys, property evaluation reports, hazard observation booklet forms and/or stakeholder group information will be transferred to the QGC GIS Database and also the QGC Protocol. This information will be used to develop weed and pest management plans over the Gas Fields and maintain knowledge of weed and pest distribution. It will also assist document landholder discussions, what weeds and pest were present prior to commencement of gas field development and effectiveness of management. An exchange of Weed and Pest information between QGC and Biosecurity Queensland will be investigated to improve management planning and responsiveness. 5.3 Monitoring Monitoring and control of weeds and pests will be conducted on an ongoing basis for the life of the Gas Field. Monitoring of weed and pest infestations within disturbed areas will occur at least monthly during construction and then quarterly for a period of two years following construction. Appropriate weed and pest control measures will be applied. Following the two year period, the frequency of monitoring will be reconsidered dependent on the success of control measures and the level of infestations. Weed and pest management is an integrated and evolving process and amendments to strategies must occur regularly as new information becomes available and new control techniques are developed. Weed strategies also need to be amended when the pattern of weed infestation changes. It is proposed that in the event new significant weed species are discovered within the Gas Field area or along associated access roads, these management strategies be reviewed. Results of monitoring will assist in identifying ways to improve weed and pest management. 46 of 100

Include responses to threats to MNES from the proponent s operational activities and land management activities including the disposal and use of associated water, damage by livestock and impacts from feral animals and weeds; Note: The proponent may develop the plan to satisfy the requirements of both the Queensland Government and these conditions as indicated in condition 98b). A RRRMP has been developed. This PWM Plan addresses the management of feral animals and weeds to reduce impacts on MNES. ii of 100

52 Pest and Weed Management Plan Coordinator-General imposed conditions Gas Fields. Condition no Requirement Response Part 1 General Condition 10 Weed and Pest Management 1. Prior to commencement of construction work, the proponent and its contractors must consult with the relevant officers from the Department of Employment, Economic Development and Innovation in respect to the detection and control of weeds and pests. 2. Comprehensive weed management plans to be prepared in consultation with relevant local governments and Biosecurity Queensland, for construction and operational stages of the proposed development (including gas fields, pipelines and the LNG facility). 3. The plans must be reviewed regularly and updated to ensure weed and pest management strategies are based on the most up to date information and amended in response to any changes in the distribution, priority, biosecurity risk and status of weeds and pests. 4. Pursuant to Section 52, Division 2 of the Land Protection (Pest and Stock Route Management) Act 2002, the proponent is required to make an application to the Chief Executive of the Department of Employment and Economic Development and Innovation with regard to the Wild Dog Barrier Fence and to the Darling Downs Moreton Rabbit Board with regard to the Darling Downs Moreton Rabbit Board Fence and making openings in these fences for a particular purpose and period. 5. Consistent with the National System for the Prevention of Marine Pest Incursions and in relation to activities undertaken in areas that may disturb littoral and marine areas, the proponent and its contractors must collaborate with Gladstone Port Corporation, to ensure appropriate marine pest management procedures are in place. 6. A management plan must be developed in consultation with Fisheries Queensland and Biosecurity Queensland, to detail measures designed to protect fish habitats from, and to prevent translocation of, pest fish and other water-borne pest species. 7. Any flora or fauna species (including native and exotic species) which may be translocated as a result of treated CSG discharged water into natural water bodies must be monitored and managed in consultation with Fisheries Queensland and Biosecurity Queensland. QGC has consulted with DEEDI during the finalisation of this report. This report only deals with terrestrial and freshwater weeds and pests. Marine pests will be dealt with separately. iii of 100

53 Pest and Weed Management Plan Part 3 CSG model conditions Schedule D Land Pest Management (D24) In carrying out the petroleum activity(ies) the holder of this environmental authority must develop and implement an effective pest management program that includes but is not limited to the following: a) Identification of pest species and infestation areas; b) Prevents and/or minimises the introduction and/or spread of pests; and c) Control and management of pest outbreaks as a result of petroleum activities. (D25) A copy of the pest management program must be made available to the administering authority on request. QGC has consulted with DEEDI during the finalisation of this report. This report only deals with terrestrial and freshwater weeds and pests. Marine pests will be dealt with separately.

63 Full Clean Vehicle is cleaned from bumper to bumper using appropriate methods which may include hosing down, vacuuming or compressed air blowers. Vehicle components that can harbour vegetative material are removed and cleaned. Particular attention is paid to carpets, floor mats and seats within the vehicles cab. The cleaning would be done in a designated clean down facility. All effort is must to remove all contaminates from the vehicle before it leaves an infested area. The operator is obliged to take all necessary steps to ensure that no contaminates are attached to clothing including boots, laces, sock, trouser turnups, seams, shirt cuffs or pockets. Contaminated clothing to be removed, shaken out, cleaned and thoroughly inspected prior to leaving the site. Particular attention should be paid to storage areas on the vehicle including tool boxes. If necessary the vehicle should be inspected by a third party to ensure that the risk of weed spread is reduced to an absolute minimum. Wash down All exposed areas of the vehicle are cleaned using compressed air, vacuum, brush or a high pressure spray. Particular attention is paid to the carpets, floor mats and seats within the cab, wheel wells, running boards and radiator. Operator must ensure that prior to leaving a contaminated area all clothing (boots, socks, pants, pockets, laces and shirts), toolboxes and storage compartments are free of contaminates. Wash down should be conducted at a designated wash down facility. All reasonable effort must be made to ensure that both the operator and the vehicle, toolboxes and equipment are free of contaminates prior to leaving an area. Visual Inspection and shake down A visual inspection of the vehicle is made, including the radiator, wheel wells, running boards and particularly the carpets, floor mats and seats within the cab. Any suspicious seeds are brushed of prior to leaving a site. If seeds or vegetative materials are found or cannot easily be removed and disposed of the vehicle is taken to a designated clean down facility within the core infestation area and procedures under the wash down recommendation are followed. The operator must ensure that all personnel effects including toolboxes, equipment and clothing are free of contaminates prior to moving off site. ii of 100
