The purpose of the 25 day shutdown is to complete maintenance tasks that cannot be completed when the plant is online. Whilst the major focus is on maintenance activities, environmental issues have not taken a back seat. A daily newsletter has been developed for the shutdown. In addition to safety information, the newsletter includes environmental statistics such as the number of waste audits conducted, the number of environmental near misses and the number of environmental incident reports generated. With up to 250 contractors on site on any one day, waste volumes and waste segregation have the potential to be a large issue. Targeted waste audits are being conducted by the site Environmental Scientist. To date 46 waste audits have been conducted with 7 environmental near misses raised due to incorrect waste segregation. One page lessons on spills, correct waste segregation and waste disposal have also been generated during the shutdown and included with the daily newsletter for distribution to the site. The volume of waste to landfill generated during a shutdown year is substantially greater than a normal operating year. Waste audits are part of the site’s waste minimisation activities to ensure that all possible wastes are appropriately recycled and that minimal non-recyclable waste is sent to landfill. There has been one environmental incident during the shutdown. This involved a spill of 5-10 litres of diesel from a contractors vehicle. The spill entered the ash ponds through the stormwater system, however was treated with Comprox successfully. Thank you to everyone for their dilligence and hard work in remembering to consider the environment whilst conducting these crucial maintenance tasks.

The role of Community Relations Officer incorporates community and stakeholder engagement, and local government and media relations. The CRO develops and implements programs designed to build and maintain the necessary relationships with internal and external stakeholders, particularly the Anglesea community. Is Anthea returning to Anglesea? Yes, Anthea returns to the Anglesea CRO position three days a week in early July. I understand you are now leaving Alcoa. Where are you off to and what does the new job entail? Sadly April 24th was my last day working with Alcoa Anglesea. Even though I have only been with Alcoa for 18 months, it has been a wonderful experience. However, I am very excited to be commencing a new position with Barwon Water. I will be the Education Officer and will be responsible for hosting tours of Barwon Water facilities, developing educational resources, undertaking community speaking engagements and developing education and community strategies. Thanks for all your hard work, Dave. We will miss you! ...DAVE RYAN
