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.

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! ...NICK BROCKMAN
