ANGLESEA ENVIRONMENT REPORT JANUARY 2010
2009 - the year in review
2009 was a very busy year for the Anglesea Power
Station’s environmental team. Not only did we
complete the “every day” work such as the EPA
annual report, reporting to the National Pollutant
Inventory, our community reporting and participating in
a review of our ISO14001 systems, but we also
completed a long list of additional work, including:
- 2009 Maintenance Shutdown;
- Submission and approval of EPA Energy
and Resource Efficiency Plan;
- Reaccreditation of Wastewise certification
to Gold Level;
- Commissioning and 53V Audit of the SO2
Air Quality Control System (AQCS); and
- Reporting to the new Federal Government
National Greenhouse and Energy
Reporting Scheme (NGERS).
Here is an update on how we went during 2009 in our
major areas of focus that we report on every month on
the back page of this report.:
Emissions to Air: one reportable environmental
incident involving an exceedance of the EPA Air
Quality Objective of 200 ppb SO2 in March.
Greenhouse Gas: GHG Efficiency slightly exceeded the
target of 1.20, with an annual average of 1.21. This is
an area of focus for 2010, and we plan to improve this
efficiency to below 1.20. Due to the introduction of
NGERS, our GHG emissions have had to be
recalculated back to Jan 2008. This may account for
any discrepancies in GHG figures that you see in this
report compared to previous versions.
Town Water Use: during our shutdown we used 2.0
ML of water for our maintenance activities. However,
our annual town water use exceeded our 2009 target
of 14.2 ML by exactly that amount. As this is an
irregular activity, we plan to be able to meet our target
in 2010.
Bore Water Use: our bore water use was well below
target for 2009. 2814 ML were used, as opposed to
our target of 4000 ML.
Waste to Landfill: the amount of non-recyclable waste
that was sent to landfill in 2009 was 11.64 tonnes. This
did not compare favorably to our target of 8.0 t. The
reason for the large volume of waste produced was
mainly the maintenance shutdown and the several
hundred contractors on site during that time period.
However, on a positive note, no prescribed waste
requiring landfill was generated in 2009.
In addition to all this, we helped to fight a planned burn
which broke containment lines and threatened our
perimeter, we commissioned our new Northern
Meteorological station to help with predictive alarms for
the AQCS, our Peregrine Falcon pair - Sheila and
Havoc - produced three healthy chicks, we
commenced work on our Cultural Heritage
Management Plan and we rehabilitated a small area in
the mine lease of 0.658 ha!
We have set new environmental targets for 2010.
These can be seen on the last page of this report. We
look forward to working hard in 2010 to achieve these
targets.
ANIMAL OF THE ANGLESEA HEATH
TIGER SNAKE (Notechis scutatus)
Size:
Description:
average 1 m; maximum 2 m
despite the name, the snake may have no
striping at all; markings are extremely
variable and colour varies, from jet black,
through yellow/orange with grey bands to
sandy grey with no bands; typical forms are
a black or dark olive snake with either no
bands or faint yellow or cream bands
Distribution + Habitat: the common tiger snake is found in
southern and eastern Australia; wide
ranging from dry rocky areas, woodlands,
to wet marshes and grasslands.
Food:
mainly feeds on small birds and mammals
under 300g in weight; also lizards + frogs
Tiger snakes are aggressive if disturbed or threatened,
however they will not bite unless provoked. Venom is highly
toxic but human death from snake bite is uncommon as anti
venene is readily available.

OUR ENVIRONMENT AND OUR EMPLOYEE
Steve, I understand as part of your work at Anglesea as an
Alcoa Business System (ABS) consultant, you participated
in a diesel fuel use mapping session. What did this involve
and why was it important to do?
The process involved having a focussed two hour session with a
select group of employees who have knowledge of the supply,
cost, infrastructure and consumption of diesel at Anglesea. The
outcome is we now have a detailed flow map and have identified
11 opportunities to potentially reduce our diesel usage rate.
Diesel is a large annual cost to the Anglesea business and also
environmentally is considered a “significant resource” under our
ISO14001 program. Finding ways to reduce our diesel use per
MWh not only can save the business dollars, but also reduces
our environmental footprint.
How do you see your role in ABS and the environment
fitting together?
ABS defines how we do business. My role is to help develop
systems and teach in the “thinking” of ABS so we are all better
equipped to continually improve our business in areas of cost,
time, quality, environment and health and safety. improving in
these areas is the key to growing our operations and meeting the
expectations of our shareholders and our communities.
