2009 shutdown underway
Alcoa Anglesea’s 2009 maintenance shutdown
began on Tuesday April 27 and is currently in full
swing. 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.

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Dave, I understand you are backfilling Anthea
Doran’s role during her maternity leave - what does the
role involve? 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
