Environmental Impact Report Summary Beach Energy Limited and its group subsidiaries (Beach) hold a number of petroleum exploration, production and retention licences in the onshore Otway Basin in the South East of South Australia. This Environmental Impact Report (EIR) has been prepared by Beach under the Petroleum and Geothermal Energy Act 2000 to cover Beach’s ongoing geophysical operations in the region. Previous EIRs (and associated Statements of Environmental Objectives (SEO)) covering geophysical operations in the Otway Basin region were developed by the Department of Energy and Mining (DEM) (see Roberts, 2001; Annear, 2013). This EIR (and associated SEO) updates and supersedes previous EIRs and SEOs developed to cover geophysical activities in the region.
