The Petroleum Lease (PL 1037) is located west of Wandoan in southern-central Queensland. To commercialise production, new gas processing, compression and transportation infrastructure operated by Jemena Ltd (Jemena) is proposed to be constructed adjacent to Senex’s PL 1037, the ‘Atlas Lateral Project’. The Atlas Lateral Project will include a ‘Gas Compression Facility’ and accompanying 60 km of pipeline connecting to Senex’s adjacent PL 1037. The Gas Compression Facility is proposed to be located within an area of approximately 350m x 250m (8.1 ha). This report documents the baseline values that are associated with the Gas Compression Facility and a 300 m buffer area surrounding the Gas Compression Facility Area with a focus on impacts to matters of national environmental significance (MNES) and matters of state environmental significance (MSES). The terrestrial and aquatic ecological values of the proposed Gas Compression Facility Area and buffer area were assessed using desktop sources, with additional field surveys conducted by suitably qualified ecologists to assess ecological values. Desktop sources included available mapping products and species database records. The outcomes of the desktop assessment and field surveys were analysed to inform a likelihood of occurrence assessment relating to listed threatened species and ecological communities. No MNES, MSES or ESAs occur or are considered likely to occur within the Gas Compression Facility Area. However, one small area (0.16 ha) of Brigalow TEC (MNES) and habitat for listed threatened species (based on likelihood of occurrence assessment) for the koala (0.64) (MNES and MSES), glossy black cockatoo (0.16 ha) and golden-tailed gecko (6.56 ha) (MSES), and remnant and regrowth vegetation that are considered ESA’s occur within the buffer area. No direct impacts will occur to MNES, MSES and ESA’s as a result of development of the proposed Gas Compression Facility. Consequently, the proposed activities are unlikely to have a significant impact on any regulated matters and the extent of direct disturbance is considered to be minimal. 1 INTRODUCTION Environmental Resources Management Australia Pty Ltd (ERM) has been engaged to document the terrestrial and aquatic ecological values, to support the development of approvals documentation for ‘Project Atlas’, a coal seam gas field in the Surat Basin in southern-central Queensland, which is an established gas-producing region. Project Atlas will involve the development of production wells and supporting infrastructure to produce gas exclusively for the domestic market. At least 25 years of commercial gas production is anticipated. To commercialise production, a new gas processing, compression and transportation infrastructure is required and will be constructed, owned and operated by Jemena Ltd (Jemena), the ‘Atlas Lateral Project’. The Atlas Lateral Project (the ‘Project’) will involve infrastructure to receive low pressure gas ENVIRONMENTAL RESOURCES MANAGEMENT AUSTRALIA PTY LTD 0461545/FINAL/21 SEPTEMBER 2018 1 from Senex’s adjacent PL 1037. Gas will be compressed and processed suitable for domestic sales, and transported the gas to the Wallumbilla gas supply hub via new and existing pipelines. The ‘Gas Compression Facility’ will comprise a pipeline of approximately 60 km connecting Senex’s PL 1037 to Jemena’s Darling Downs Pipeline. The Project Area is located near the townships of Wandoan and Wallumbilla. The tenement is immediately south of QGC’s Polaris and Cameron graticular blocks within the Northern Development Area of the QCLNG project, approximately 44 kilometres north of the Warrego highway. Located adjacent to the Project Area is Origin’s Ramyard gas field to the south, the Sandpit field the northeast and the Woleebee gas field to the east (Figure 1.1). 1.1 PURPOSE OF THE REPORT The purpose of this report is to document the terrestrial and aquatic ecological values associated within the Gas Compression Facility Area and in turn identify risks to biodiversity values and avoidance, mitigation and management measures. The Gas Compression Facility will be located adjacent to the Production Area at the northern boundary (Figure 1.1). The Gas Compression Facility Area will encompass approximately 8.1 ha and works within the Area will involve vegetation clearing and construction works. Within this report, the Gas Compression Facility Area is defined as the 350 m x 250 m footprint for the Gas Compression Facility. This assessment includes a 300 m buffer around the Gas Compression Facility Area. The description of baseline ecological values is provided to support an application for a site-specific Environmental Authority (EA) for the Gas Compression Facility and assessing whether a significant impact on MNES is likely under the Environment Protection and Biodiversity Conservation (EPBC) Act 1999. The structure of this report is aligned with information requirements of relevant approval guidelines and applications. A separate document focusses on the baseline ecological values of the Production Area and Pipeline Area. 1.2 SCOPE OF THE ASSESSMENT The scope of the report includes assessment of terrestrial and aquatic species and habitats associated with the proposed Gas Compression Facility Area and 300m buffer, with particular focus on: ENVIRONMENTAL RESOURCES MANAGEMENT AUSTRALIA PTY LTD 0461545/FINAL/21 SEPTEMBER 2018 2 Biodiversity values as defined by the Department of Environment and Science (DES) Streamlined model conditions for petroleum activities 2016, including Environmentally Sensitive Areas (ESA), prescribed environmental matters and wetlands; Matters of State Environmental Significance (MSES); and Matters of National Environmental Significance (MNES).
