alternative fuel trials – project updates
Alcoa Anglesea is continuing to undertake and
monitor the results of an alternative fuel trial of
soy-based bio diesel in its mine fleet, while a
second trial using HiCAL40 previously proposed
to get underway in the second half of this year
remains on hold.
strategic
sustainability
targets
around
conserving resources, sustaining operations and
reducing waste and greenhouse gas emissions.
As profiled in our last edition, a four-month trial
of a soy biodiesel product in the mine fleet
began on 1 June 2010. The product is being
used to fuel the earthmoving fleet, in a bid to
further reduce greenhouse emissions across the
site. Alcoa will continue to monitor the project for
the remaining weeks of the trial. A project
evaluation will then occur to determine if Alcoa
equipment to B20 soy-diesel.
The second proposed alternative fuel trial aims
to replace a small proportion of the current coal
input with a carbon-based fuel known as
HiCAL40. This alternative fuel is already
successfully used in other industries and
provides a range of benefits to the companies
which use it. The success of these projects has

Anglesea Power Station to determine the
potential to develop new markets for the
product.
Alcoa applied for an EPA Research,
Development and Demonstration (RD&D) permit
to conduct the trial, but the trial is not yet active
and remains on hold while we continue to review
a range of technical and environmental, health
and safety (EHS) aspects of the project. No firm
start date for the project has been decided at
this point, but if and when it does get approval
to commence we will keep our employees and
the community updated through our existing
communication channels such as this report,
Talking Points, our bi-monthly Community
Consultation Network meetings, our quarterly
site newsletter and our website.

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Nicci. What environmental approvals are required for
trials such at the HiCal40 Trial? We were advised by the
EPA to submit a Research, Development and Demonstration
(RD&D) application for the trial. This application requires
approval from the EPA and has a 12 month timeframe.
What sort of information was included in the RD&D
Application? We engaged various consultants with
knowledge on the HiCal40 product to make considerations on
the potential impacts to air, water and land. The
recommendations and information provided by the consultants
was included in the application.
What was your involvement in the HiCal40 Road show?
I was part of the team who gave a presentation to all personnel
on site. We wanted to ensure that everyone had a clear
understanding of the trial intent, the testing that had been done
and to give them an opportunity to ask questions face to face.
We had lots of really good questions and discussions during
the road show.
If the trial does go ahead in the future, what will be
required from EPA’s perspective? We will need to provide
ongoing monitoring and reporting to the EPA throughout the
trial duration and a comprehensive post-trial report.
