Section 44 of the Environmental Protection Act 1986 (EP Act), read with section 40B, requires the Delegates to report to the Minister for Environment on the outcome of their assessment of a strategic proposal. The report must set out: the key environmental factors identified in the course of the assessment; and the Delegates’ recommendations as to whether or not the future proposals identified in the strategic proposal may be implemented and, if the Delegates recommend that implementation be allowed, the conditions and procedures to which implementation should be subject. The Delegates may include in the report any other advice and recommendations as they see fit. The Delegates are also required to have regard for the principles set out in Section 4A of the EP Act. Key Environmental Factors and Principles The Delegates identified the following key environmental factors in the course of the assessment. A detailed evaluation of these key environmental factors is provided in this report: (a) Benthic communities and habitat; (b) Coastal processes (c) Marine environmental quality (d) Marine fauna (e) Flora and vegetation (f) Terrestrial fauna (g) Hydrological processes (h) Air quality and atmospheric emissions (i) Heritage (j) Rehabilitation and decommissioning – integrating factor; and (k) Offsets – integrating factor. There were a number of other factors which were relevant to the proposal, but the Delegates did not identify these as being key environmental factors and are i of the view that the information set out in Appendix 3 provides sufficient evaluation of these factors. In conformity with s4A of the EP Act, where relevant, the following principles were considered by the Delegates in relation to the proposal: (a) The precautionary principle; (b) The principle of intergenerational equity; (c) The principle of the conservation of biological diversity and ecological integrity; (d) Principles relating to improved valuation, pricing and incentive mechanisms; and (e) The principle of waste minimisation. Appendix 3 provides a summary of how the Delegates considered these principles. Recommendations That the Minister for Environment notes that: 1. the proposal being assessed is a strategic proposal to establish a Common User LNG Hub Precinct at James Price Point in the Kimberley to process gas from the Browse Basin; 2. the Delegates, having assessed the strategic proposal by the Minister for State Development to establish a Common User LNG Hub Precinct at James Price Point in the Kimberley to process gas from the Browse Basin, make the following recommendations: a. the future proposals identified in the strategic proposal, as detailed in Section 2 of this Report, may be implemented; and b. the implementation of the future proposals should be subject to the applicable1 conditions and procedures set out in Appendix 4 (which are summarised in Section 4), so as to ensure the future proposals meet the environmental objectives discussed in this Report. 3. the Delegates have concluded that the environmental objectives for the key environmental factors identified in this Report are likely to be achieved provided the recommended conditions and procedures set out in Appendix 4 (which are summarised in Section 4) are imposed and complied with in the implementation of the relevant future proposal; and 4. the Delegates’ other advice presented in Section 5 in relation to proposal design and other matters. 1 Section 45A(3) of the EP Act provides that if the implementation agreement or decision previously made in relation to future proposals, declared a derived proposal, includes implementation conditions relating generally to two or more future proposals, the Minister may, in the notice issued under section 45A(2), specify which of those implementation conditions apply to the derived proposal ii Conditions Having considered the information provided in this Report, the Delegates have developed a set of recommended environmental conditions to be imposed if the future proposals identified in this strategic proposal are approved for implementation. These conditions are presented in Appendix 4. Matters addressed in the conditions for future proposals include the following: (a) A Marine Fauna Baseline Report to establish the baseline status of conservation marine fauna at the time a derived proposal is to be implemented. (b) State of the Marine Environment Surveys to establish the baseline state of the marine environment, including water quality testing and benthic habitat mapping. (c) A Marine Facilities and Impact Zones Plan to demonstrate that impacts to the marine environment have been minimised and define the zones of impact through updated modelling. (d) A Dredging, Marine Facilities and Pipeline Installation Environmental Monitoring and Management Program to achieve the required environmental protection outcomes for the marine environment. (e) A Pipeline Shore Crossing Management and Monitoring Program to ensure that pipeline construction minimises the impacts to the intertidal area. (f) A Coastal Processes Management and Monitoring Program to manage the impacts on coastal processes. (g) A Marine Construction and Operation Environmental Quality Management Plan so as to ensure impacts on marine environmental quality are minimised. (h) Management of hydrotest fluids to prevent impacts of discharges, including a prohibition on discharging untreated fluids in State waters. (i) A requirement to resource oil spill response equipment and personnel. (j) A Coastal Dolphin Survey and Management Program to improve the knowledge base in regards to coastal dolphins. (k) A Conservation Significant Marine Fauna Interaction Management Program to avoid impacts to marine fauna from activities associated with the proposal. (l) Management of the proposal to prevent the introduction of marine pests. (m)A Terrestrial Baseline Report to establish the baseline status for conservation significant flora and fauna. (n) A Terrestrial Disturbance Plan to demonstrate that clearing of native vegetation will be carried out in a manner that minimises the impacts to conservation significant flora and fauna, including clearing not more than 110 hectares (ha) of the Monsoon vine thickets on coastal dunes of Dampier Peninsula Threatened Ecological Community. iii (o) A Terrestrial Environment Management and Monitoring Plan to ensure the project is being implemented in a manner that minimises impacts to terrestrial flora and fauna. (p) Installation of equipment and management of operations to best practice standard to minimise air emissions. (q) Reporting of greenhouse gas emissions. (r) A Greenhouse Gas Management Plan to demonstrate emissions will be reduced to as low as reasonably practicable. (s) Heritage Management Plans that require protection zones and other management measures to minimise impacts on significant heritage areas, particularly Aboriginal heritage. (t) Progressive rehabilitation of areas that are no longer required for ongoing operations. (u) Decommissioning at the end of the project’s life. (v) An Offsets Program consistent with the Western Australian Government Offsets Policy. iv Contents Page Summary and recommendations .................................................................. i 1.
