fuel-reduction burn
Strategic fuel reduction burns are generally
conducted in order to reduce the bush fire risk in
future seasons. The bush fire risk was incredibly
real for Alcoa Anglesea on Saturday March 28,
when a Department of Sustainability and
Environment (DSE) fuel-reduction burn
appropached the perimeter of our operations.
High priority burns are currently occurring along
the Otway Coast - Great Ocean Road as part of
DSE’s fuel-reduction strategy. Planned burns are
proven to reduce bush fire risk and protect
communities and assets by reducing the fuel load.
A number of burns are also important for
managing ecosystem health.
A planned burn was initiated by DSE on Friday
March 27 on a parcel of land to the north of the
Power Station, about 3 km from the Anglesea
Township. However, around 15:45 the fire had
broken containment lines and was approaching
our operations.
The CFA were called on site shortly after as our
coal stockpiles were threatened.
A bulldozer from the mine was employed to create
a containment line at our fencline and our 60,000L
water tanker was used to wet the coal stockpiles
and around the perimeter fence. The water tanker
was also used for fire suppression within the plant
boundary fence.
Our ash ponds and fire services dam were also
provided to DSE for refilling of water bombing
helicopters.
By 16:30 the fire was up to the Alcoa Anglesea
fenceline. However, the wind direction changed
and pushed the fire away from our operations.
The fire was officially termed “controlled” on
Monday 30 March at 12:00. The total area burnt
was 607 ha.
Great work by our employees, combined with DSE
and CFA, ensured all personnel remained safe
throughout the ordeal and no assets were lost.
DSE have several more fuel reduction burns
planned for the coming months in order to reduce
the fire risk to Anglesea - stay tuned!

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Garry, what is your role at the Power Station? I am a
Power Station Operator 6 (Shift Supervisor/Unit Controller).
This means that I lead the team of four operators on shift.
Can you explain the events that occurred during the
recent fire? How close did it come to the station? The
fire had proceeded beyond the planned boundary of the
controlled burn and into the swamp on the west side of the
station. Fire activity increased during the day and was
moving slowly towards the station’s emergency coal
stockpile. The fire came to the station boundary fence
which is within 50m of the emergency coal stockpile.
What actions did you and other Alcoa personnel have
to take to assist in protecting our assets? Wetting
sprays were put on the emergency coal stockpile “just in
case”. The CFA were notified and ERT personnel from the
mine responded. The mine water cart was used to wet
down the bush on the perimeter fence, and the mine tracked
dozer was used to put a mineral earth break around the
edge of the fire.
...GARRY PARIS
