world environment day
World Environment Day (WED), commemorated
each year on June 5, is one of the principal vehicles
through which the United Nations stimulates
worldwide awareness of the environment and
enhances political attention and action.
Established by the United Nations General
Assembly in 1972, WED gives a human face to
environmental issues; empowers people to
become active agents of sustainable and equitable
development; promotes an understanding that
communities are pivotal to changing attitudes
towards environmental issues; and advocates
partnership which will ensure all nations and
peoples enjoy a safer and more prosperous future.
World Environment Day is a people’s event with
colourful activities such as street rallies, bicycle
parades, green concerts, essays and poster
competitions in schools, tree planting, as well as
recycling and clean-up campaigns. Here at Alcoa
Anglesea, there were several WED activities
involving employees and the wider community.
Over 1000 indigenous trees and shrubs were
planted in the mining area by two dedicated tree
planting crews. The first session consisting of
Graeme Kerr, Leigh Fonseca, Maryann Thorp,
Barry Knight, Tony Cust, Elise Jeffery and Chris
Rolland, planted trees and shrubs along Coalmine
Road as part of the strategy to minimise the visual
impact of the open cut mine. The second session
involved Daryl Carson, Keith Giles, Jonathon
Morrow, Elise Jeffery and Chris Rolland planting
and mulching trees and shrubs around the mine
lunchroom area to remove weed species and
create bird-friendly habitat using indigenous
species for the smaller local birds.
Alcoa Anglesea also participated with the Surf
Coast Shire, CCMA, Barwon Water, Eco Logic and
Rural Ambulance Victoria in an environmental
awareness activitiy involving 300 school children.
To complete the WED celebrations, Alcoa
Anglesea was named a finalist at the United
Nations WED Awards for land management.

OUR ENVIRONMENT AND OUR EMPLOYEES..
Graeme, it was great to see the mining crews involved
in some tree planting to celebrate World Environment
Day
Day.. How did you enjoy the activity?
It was good to help out. We planted a lot of trees along
Coalmine Road.
How do you consider the environment in your day to
day work?
On a daily basis, our main consideration for the environment for
the mining operation is controlling the dust. Recently I was
involved in some drainage work in the strip area diverting water
and silt from Coalmine Road and a berm of the open cut from
running across the strip area into the unmined heathland.
Is it a challenge mining in an area as environmentally
sensitive as Anglesea?
It is a challenge however we work to minimise our environmental
impact as best we can. For example, when we are clearing new
areas, we work within the plans set out by Tony and Elise to
ensure we don’t clear more than we have to.
