cultural heritage management plan
New Victorian Government Aboriginal Heritage
Regulations came into effect in 2007, which have
changed the way in which Alcoa Anglesea approaches cultural heritage. In order to proceed with
any vegetation clearing and mining in the future, we
need to have an approved Cultural Heritage Management Plan (CHMP).
The Wada wurrung clan are the traditional owners of
this land. Their territory extends along the coast from
Painkalac Ck at Airey’s Inlet to the Werribee River and
north as far as Mt Emu Creek. There are few direct
historic accounts of Aborignal people for the Anglesea
area. In the absence of this information, archaeological sites and materials are often the only means of
gathering information about the aboriginal past.
Alcoa Anglesea values the relationship and engagement we have with the traditional owners of the land
we now mine. Previously, Alcoa Anglesea had worked
hard to establish a Memorandum of Understanding
(MOU) with the Wathaurong Co-operative. However,
the new legislation has legally invalidated this MOU.
We are now required to enlist the assistance of a
government approved Cultural Heritage Advisor and
work in conjunction with a Registered Aboriginal Party
(RAP).
The newly appointed RAP for our area is the
Wathaurung Aboriginal Corporation. Although the
name is similar, this is a different group to the one with
which we held the MOU.
A walk through survey was conducted in early
December to assess the presence of any cultural
heritage items. Despite horrendous weather, several
stone artefacts were found on the soil surface and
documented.
Our Cultural Heritage Advisor and two representatives
from the RAP returned a few weeks later to conduct a
week of sub-surface testing. This involved the digging
of many pits and seiving all dirt removed from the pit.
This is done to ascertain the presence of any artefacts
below the ground surface. However, after much
digging and seiving, no sub-surface artefacts were
found.
The CHMP will be written up by our Cultural Heritage
Advisor over the next few weeks and then reviewed by
the Wathaurung Aboriginal Corporation shortly
thereafter.
Once Alcoa Anglesea has received the approved plan,
we are able to begin vegetation clearing and continue
the progression of the current mine pit.

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Nick. I understand that some of your work in 2009
involved the development of an alternate haul road.
Why was this done?
This was done to enable the 2010 rehabilitation program to
fill in the gully at the entrance to the mine where coal had been
previously hauled. This would also optimise the coal hauling
distance as the coal reserves are now located to the north.
What will happen to the old haul road?
The main part of the old haul road will be left in tact and used
as an overburden haul road in the near future as we fill in the
entry to the mine. The decommissioned section was
stripped of its crushed rock, which was recycled and used on
other haul roads and the remainder stockpiled.
What environmental considerations have you had to
take into account during this work?
The main environmental considerations included setting up
for the 2010 rehabilitation season, drainage of the haul roads
and dealing with the associated rainwater runoff.
Thanks Nick!
