You know when the autumn leaves turn from green to gold, the sky is a brilliant, cloudless blue and the mornings feel crisp that it’s time to.... warm up the mulcher!! The harvesting of the understorey for mulch was the first mine rehabilitation task on the agenda. This basically involves slashing the understorey with a mulcher with the material collected in the trailer behind. This is then stored undercover to be spread on the rehab area later in the process. After missing out on the mulching task last year due to some badly aligned annual leave, Wayne Lee was back in the drivers seat weaving the tractor through the heathy woodland collecting as much mulch as possible. As the understorey was collected, Brent Lee delicately cleared the strip area of the overstorey with the D10 dozer. Don’t try this at home folks, delicate ain’t easy to do with a D10. And a delicate operation it is. With the most valuable seed source for the mine rehabilitation located within the first five centimetres of the soil, churning up of the topsoil needs to be minimised. The trees are currently stockpiled and will be placed in the mine rehabilitation area this year to assist with erosion control and provide fauna habitat. After clearing, a foot survey of the strip area was conducted for archaeological sites by TerraCulture and a member of the Wathaurong Cooperative. No artefacts were located in the strip area. And that’s where the mine rehabilitation update ends for this month. The slope within the open cut for the 2007 rehabilitation season is still in the process of turning from overburden dump into rehabilitation slope. A long and difficult process with overburden carted between the furthest extremes of the open cut. Stay tuned next month as the scrapers arrive and get some soil on the move.

Lisa - this is your second stint at Anglesea, what have you been doing in between? Since I was here in 2003 I have worked as the Environmental Consultant at both Point Henry and Portland Smelters. Whilst it has been difficult moving positions so frequently, it has given me a good insight into how the different locations operate. I have also taken 12 months off on maternity leave during 2006. And what does the future hold? I am heading back to Point Henry in the next few weeks to take up the position of Quality Manager for the Vic Ops Environment and Occupational Hygiene groups. Your impr ession/highlights of your time at impression/highlights Anglesea? Anglesea has been my favorite location to work at. I like the ‘can do’ attitude everyone has. Everyone has been so willing to help me when needed. ...LISA MILLS
