Executive Summary Environmental Management Plan for Fairview Project Area – May 2008 The Fairview Project Area (the Project), Environmental Management Plan (EMP) relates to continued Coal Seam Gas (CSG) development in the southern Bowen Basin, Queensland developed by Santos TOGA Pty Ltd (Santos). The EMP is in support of an application for a single integrated Environmental Authority (EA) for six existing Petroleum Leases (PLs): 90, 91, 92, 99, 100, 232 and Pipeline Licences (PPLs) 76 and 92. The single integrated EA will replace existing individual EAs for these PLs. The Project area consists of existing petroleum operations across the six PLs developing CSG reserves and delivering up to 75TJ/day. The EMP describes the expansion of the six PLs through the 2008 development program to deliver a field capacity of 115TJ/day in 2008. The 2009 expansion of the Project is forecast to expand field gas deliverability to 145TJ/day. Description of the Project The Project expansion across the six PL’s includes; • Non-production wells to further prove reserves including; appraisal wells and single well pilots. • Groups of production wells surrounding existing development areas with gas and water gathering systems and transfer pump stations. • Associated water management including: a reverse osmosis treatment facility, injection facilities and localised storage facilities. • Gas field and export compression sites. • Support infrastructure including; camp facilities, borrow pits and road upgrades. Existing environment The Project is located in a rural area of low population density in the southern Bowen Basin, Queensland. The closest urban centres to the Project are Injune, 17 km to the west, Roma, 75 km to the south, Taroom, 65 km to the east and Rolleston, 100 km to the north. Figure 1 indicates the location of each PL and PPL in the Project area. The landscape in the Project area has been significantly altered by non-petroleum clearing and agricultural activities including pastoral (livestock) activities and cereal cropping, particularly in the south-west of the Project area (PL91, 92, and central areas of PL100). The Project area encompasses areas of freehold land with areas of remnant and regrowth vegetation and areas of National Park and State Forest. Prepared for Error! Unknown document property name.

Executive Summary Figure 1: Project Location Map Potential impacts The potential environmental impacts of the Project activities have been assessed as part of the EMP. The assessment considered the proposed activities, the existing environment and potential impacts. The following environmental factors were considered as part of the assessment; air quality, surface and ground water, produced water, noise, waste, land, nature conservation and the community (including landholders). Where assessment determined potential impacts associated with Project activities, Project specific mitigation measures were developed to be implemented. Examples of proposed Project specific mitigation measures identified are presented below in Table 1-1. An example of an environmental impact identified in the EMP is vegetation clearing. As part of its vegetation management strategy, Santos has planned development activities so as to minimise vegetation clearing, particularly within mapped areas of Semi-evergreen Vine Thicket, Brigalow and Bluegrass (threatened ecological communities). Santos is proposing to develop a biodiversity offset program within the Project area, which may involve an area of revegetation to re-establish a biodiversity corridor between existing but geographically isolated ecological communities. The EMP identifies the value of the community and potential impacts associated with the Project. As part of the Project, Santos has engaged directly with impacted landowners. Ongoing consultation will be undertaken with landowners and stakeholders during the Project. Prepared for Error! Unknown document property name. Executive Summary Mitigation Strategies Table 1-1 provides proposed mitigation strategies defined in the EMP. Table 1-1 Fairview Project Area Mitigation Strategies*. Mitigation strategy Air Air emissions from activities related to Santos action will be within regulatory requirements set out in the Environmental Authority and the Environment Protection (Air) Policy 1997. During Project planning, longer-term Project facilities, such as compressor stations, flares, stacks will be, to the extent practicable, sited away from sensitive receptors to minimise impact of air emissions. As required, air dispersion modelling to assess potential impacts of emissions and monitoring for new facilities will be conducted. Consideration shall be given during location planning for well sites and processing facilities to prevailing wind directions away from residential properties as far as reasonably practical and plan flaring / venting around prevailing wind conditions to minimise nuisance of gas plumes. Water Management options for produced formation water include: • Beneficial reuse; • Injection without intermediate storage; • Direct use; • Treated use; • Disposal via evaporation ponds; and • Disposal via discharge to grade. Noise Santos has a general noise emission specification for purchased rotating equipment such as generators, pumps and compressors on rigs of a sound pressure level (A-weighted) of no more than 85 dB(A) at 1m from the housing [NB: this standard does not necessarily apply to large fixed plant items such as compressors at stations]. All new field and export gas compressors will be fitted with hospital grade silencers. Santos maintains a complaints management system, incorporating a complaints register, recording and reporting process, investigation and response procedure. Complaints will be followed up within 48 hours of receipt and the investigation and response will be conducted in a timely manner. Prepared for Error! Unknown document property name. Executive Summary Waste The Santos EHS Hazard Standard for Waste (EHS04) shall be followed at all times and for all facility operations to ensure appropriate management of waste. Recyclable wastes (including glass, paper and plastic) will be segregated and transported to the offsite Injune Landfill and Recycling Facility as a preference, whenever possible. Sanitary biosolids or sludge from central camp locations with sewage treatment operations will be disposed at commercially licensed offsite facilities as necessary. Land The general control strategies for managing land management are as follows: • When scouting for proposed sites or corridors, Santos Environmental Hazard Standard EHS01 Land Disturbance will be followed; • Minimise disturbance to land – only drive on designated access tracks; and • Clean up spills and prepare incident report to identify root cause. Over time, identify trends and carry out additional training, equipment maintenance, etc. as necessary. Rehabilitation The general control strategies for managing rehabilitation activities are as follows: • Santos will rehabilitate disturbed areas as soon as possible after disturbance; • During earthworks, strip topsoil and store separately from subsoil, for re-use in rehabilitation. Disturbed lands to be reshaped to stable landform similar to that of similar undisturbed surrounding areas; • Santos will monitor land disturbance surrounding new project areas; • Santos will conduct environmental compliance audit post-decommissioning to evaluate effectiveness of rehabilitation, and carry out remedial work as necessary as detailed in Santos EHSMS11.11 Decommissioning and Abandonment.

Executive Summary Nature conservation The general control strategies for managing nature conservation are as follows: • Clearance of vegetation within 100 metres of watercourses, wetlands and springs, on slopes greater than 5%, on dispersible soils or in a way that would isolate small stands or dissect vegetation corridors will be avoided where possible. • Areas of significant vegetation within the Project area will be flagged to control access and minimise disturbance. • Santos will continue its internal environmental awareness and training program as part of the corporate EHSMS system. • Staff (specifically those involved in scouting, planning and construction) will be trained in the identification of significant vegetation that is known to occur on the site; • Field staff will receive training on sensitive environmental considerations specific to their work area. The Santos standard, EHS09 Weed and Pest Animal Control details the need for identification and management of weeds within Santos operational areas. This includes weed control on access tracks and right-of-ways, avoiding disturbance to weed infested areas, cleaning equipment and sourcing materials from weed free areas. Any control measures will be developed in conjunction with relevant government agencies and landowners. Community The Project will use a range of methods to ensure that information is distributed to, and may be received from, local community members and other stakeholders. These will include: • Regular meetings with the Shire Council. • Annual one-on-one meetings with landowners. • Direct verbal or written advice (e.g. telephone, letter, email etc.) to community members and other stakeholders. • Appointment of staff members responsible for community liaison and to provide a central point for public comment. *These mitigation strategies should be read in conjunction with the full Project EMP.
