The Anglesea borefield project, identifed in the Victorian Government’s Central Region Sustainable Water Strategy, has been brought forward three years in response to declining surface water storages, the uncertainty of a return to average rainfall, and to meet future growth in the region. Alcoa needs to ensure that all environmental and heritage factors are assessed, including avoiding construction within the Anglesea Heath wherever possible; avoiding areas of high conservation significance; and avoiding known aboriginal heritage sites to minimise the impact of construction upon the values of the Anglesea Heath. It is anticipated the borefield could provide up to twenty megalitres of water a day to customers in the greater Geelong region, including Geelong, the Bellarine Peninsula, Torquay, Anglesea, Winchelesea, Lara and Bannockburn, by the summer of 2008/09. The Agency Reference Group, formed in March, meets monthly to discuss and streamline the environmental and legislative process needed to satisfy each agency’s requirements for project approval. The group includes representatives from Alcoa in addition to the EPA, Southern Rural Water, DSE, Parks Victoria, Surf Coast Shire and Corangamite CMA. The Anglesea borefield will tap into the Lower Eastern View aquifer which extends from the eastern edge of the Otway Ranges and flows in a south easterly direction deep under Anglesea and beyond. Two borefield investigation zones have been identified. A northern investigation zone is located in the vicinity of Barwon Water’s Forest Road basin site and a southern investigation zone is located adjacent to Coal Mine Road, along the southern boundary of the Alcoa coal mine. A pipeline is required to link the southern and northern borefield sites to the pre-treatment plant at the Forest Road basin, and the pre-treatment plant to Wurdee Boluc Reservoir. The preferred pipeline alignment weaves it’s way through the Anglesea Heath from Coalmine Road to Forest Road. As land managers of the Anglesea Heath Consultants GHD Pty Ltd are working with Barwon Water to deliver this project including providing information and consulting with the community. The project information centre includes: > a project office office: on the corner of Harvey and Parker Street, Anglesea (the former DSE and Parks Victoria office). A project team member om will be in the office every Tuesday fr from 9.30am-4pm to discuss the project.

So Phil, you’re the OHS Coordinator - how do you come to featur e in this month’ s Env Report? feature month’s There’s a cross over between Safety and Environment where asbestos is concerned. Potential exposure to asbestos presents an environmental and health risk and we need to ensure that our people are aware of the health impacts and the correct handling requirements. From an environmental view, asbestos once removed from use is then considered a waste material, and it is disposed of in our onsite dedicated landfill. What is the status of asbestos training? As part of a review of training requirements for everyone onsite, it was determined that there was a need for a revamp of the asbestos awareness training material we present to all employees. Prior to formalising our training needs analysis, this material has generally been delivered in preparation for outages but now will be a regular feature of our training profile. And how is this year’ s training shaping up? year’s The general awareness package has been developed and training will be rolled out in September by myself or Nicci Marris. This will be for all Alcoa personnel and site-based contractors. ...PHIL SMITH
