EPA senior manager Matt Vincent said the group would provide advice on the "real or potential environmental impacts" from the former landfill and discuss appropriate mitigation and monitoring programs.

The group will focus on groundwater monitoring, leachate management and other liquid material in the landfill. It will also monitor the "integrity" of the landfill cap and its management.

Mr Vincent said the three members had engineering or scientific expertise relating to the assessment and management of landfills and hydrogeology.

A public meeting will be held tonight to relay this and other information discussed at last week's closed Tullamarine Landfill Rehabilitation Advisory Committee meeting.

Western Region Environment Centre chairman and TLRAC member Harry Van Moorst, who attended the meeting, said the group was still encountering the same problems as before. "The same differences that have separated us all along continue to do so - namely, how much risk there is to the community and the severity of that risk," he said.

Mr Van Moorst asked landfill manager Transpacific Industries to "put their money where their mouth is" and set up a place to treat the dangerous liquids inside the landfill away from residential areas.

Community members also told the Hume Weekly that TPI management had threatened to abandon the meeting process if the media was allowed back into the TLRAC meetings.

TPI chief operating officer Nick Badyk said the landfill operator "did not have anything to add" and was going through an adjustment phase following the redundancy of landfill division general manager Phil Carbins.

The public meeting will be held tonight from 7.30 at the Hume Global Learning Centre, Pascoe Vale Road, Broadmeadows.
