This has the effect that Santos Limited is now the ultimate holding company of Quadrant Energy Holdings Pty Ltd and its subsidiaries. It has also resulted in most of the Quadrant group of entities changing their name. For example, Quadrant Energy Australia Limited has changed its name to Santos WA Energy Limited and Quadrant Northwest Pty Ltd has changed its name to Santos WA Northwest Pty Ltd. Each entity’s ABN has remained the same. Santos WA Energy Limited on behalf of Santos WA Northwest Pty Ltd and Santos WA Southwest Pty Limited (hereafter referred to as Santos WA or Company) will be responsible for all commitments and obligations in this EP. Santos WA operates the Varanus Island Hub (VI Hub), located on the North West Shelf of Western Australia (WA). The scope of this EP comprises all infrastructure and operational activities associated with the VI Hub within State waters, including: All infrastructure located on VI; The associated offshore platforms/monopods and subsea tie-backs; Vessel based activities; The subsea pipelines, flowlines and umbilicals (within State waters) between VI and the offshore facilities; The pipelines between VI and the mainland metering station and the pipeline from VI to the marine load-out terminal; Maintenance and environment monitoring on Airlie Island; and Monitoring and maintenance activities on Airlie Island (AI). 1.1 Operator Santos WA is the operator of the activity described within this EP. Table 1-1 lists Production Licences, the operators and JV partners.

Our oceans play a massive role in Australian life – they provide us with fish to eat, a place to fish, business and tourism opportunities and a place for families to enjoy. Australians know, better than anyone, how important it is that our oceans remain healthy and sustainable. Right now, our iconic marine environment is coming under more and more pressure from industry, from pollution and, increasingly, from climate change. That is why the Australian Government has committed to creating a network of Commonwealth marine reserves around the country.

  • Simpson Oil Field Development, Offshore Abutilon Island, Lowendal Islands, North West Shelf
    Simpson Oil Field Development, Offshore Abutilon Island, Lowendal Islands, North West Shelf Apache Northwest Pty Ltd Report and recommendations of the Environmental Protection Authority Environmental Protection Authority Perth, Western Australia Bulletin 1023 July 2001 ISBN. 0 7307 6646 2 ISSN. 1030 - 0120 Summary and recommendations Apache Northwest Pty Ltd proposes to construct two offshore mini platforms and install undersea pipelines connecting existing oil/gas wells to Apache’s existing Varanus Island Hub facility. The Simpson Development is expected to run for approximately 10 years. This report provides the Environmental Protection Authority’s (EPA’s) advice and recommendations to the Minister for Environment and Heritage on the environmental factors relevant to the proposal. Section 44 of the Environmental Protection Act 1986 requires the EPA to report to the Minister for Environment and Heritage on the environmental factors relevant to the proposal and on the conditions and procedures to which the proposal should be subject, if implemented. In addition, the EPA may make recommendations as it sees fit. Relevant environmental factors In the EPA’s opinion, the following are the environmental factors relevant to the proposal, which require detailed evaluation in the report: (a) Oil spill risk – spills from the development and pipeline bundle; and (b) Artificial light – potential impacts on hatchling turtles. Conclusion The EPA has considered the proposal by Apache Northwest Pty Ltd to construct two offshore mini platforms and undersea pipelines connecting existing oil/gas wells to Apache’s existing Varanus Island Hub facility. The EPA notes that the Lowendal and nearby islands are classified as reserves for conservation of flora and fauna and are used as breeding grounds by a number of sea turtle and sea bird species which are listed in the National List of Threatened Species under the Environment Protection and Biodiversity Conservation Act 1999 (Commonwealth).

(CVN) secured four exploration permits offshore Western Australia (TP/27, EP-490, EP-491 and EP-475) covering approximately 3,700km2 in the heart of the Carnarvon Basin in Western Australia (Figure 1). Within these permit areas the intention is to drill possibly up to four exploration wells for the Cerberus drilling campaign, located wholly in State waters, where water depths are up to 30m. Drilling will be conducted using a jack-up rig and is scheduled for May 2017 but timing is dependent on rig availability, each well is expected to take approximately 16 days. 1.2 Latitude and longitude Table 1: Coordinates of Provisional Well Locations within Permit areas.

Corresponding author: Michael Johnson, School of Animal Biology (M092), University of Western Australia, 35 Stirling Highway, Crawley, WA 6009. Email: [email protected] ABSTRACT – Three species of camaenid land snails occur on Barrow Island: Quistrachia barrowensis and two previously unassigned species of Rhagada. Based on morphological re-evaluation and analysis of sequences of the mitochondrial gene COI, we have revised the taxonomy of these species, providing a clearer understanding of their geographic distributions and origins. The supposed Barrow Island endemic Q. barrowensis is synonymous with Q. montebelloensis from the Montebello and Lowendal Islands. The small species of Rhagada, confined to the northern tip of Barrow Island, is conspecific with R. plicata, whose distribution also includes the Montebellos and the Lowendals. The large species of Rhagada is described here as R. barrowensis sp. nov., known only from Barrow Island and adjacent Pascoe Island. The three camaenids represent deeply divergent lineages with different geographic origins, indicating that the local diversity on Barrow Island has come about through a complex history.

  • Status Performance Assessment: Biodiversity Conservation on Western Australian Islands Phase 1
    CONSERVATION COMMISSION OF WESTERN AUSTRALIA STATUS PERFORMANCE ASSESSMENT: BIODIVERSITY CONSERVATION ON WESTERN AUSTRALIAN ISLANDS PHASE 1 Conservation Commission performance assessments are undertaken primarily to fulfil the functions described in S 19(g) of the Conservation and Land Management Act 1984. That is to “assess and audit the performance of the Department and the Forest Products Commission in carrying out and complying with the management plans”. They will also help inform its policy development function and its responsibility to advise the Minister on conservation and management of biodiversity components throughout the State. This performance assessment was undertaken in accord with the “Conservation Commission policy and guidelines for the performance assessment of conservation reserve and forest management plans and biodiversity management in WA”. Further details are available at www.conservation.wa.gov.au. The use of Department of Environment and Conservation (DEC) data for the production of this report is acknowledged.
