Serious gaps in AECOM EIS for Landfill site, says environmental scientist

This information was prepared by Charlie Pierce, an environmental scientist who works as a Laboratory Manager for Sydney Water. He also has professional experience in the regulation of NSW landfills. It relates to the closure plan for the Alexandria Landfill ( Appendix F )which would become the new St Peters Interchange if the proposal goes ahead.

Here is some context to the information that Pierce has included in his submission to the New M5 EIS.

Alexandria Landfill – a community problem from Dial a Dump to Westconnex 

In December 2014, the Westconnex Delivery Authority forcibly acquired the massive Alexandria Landfill own by Dial a Dump. This is the site on which it plans to build the massive St Peters Interchange. Like all long term landfills, it is a highly polluted site.

The community experienced countless pollution problems with the site during the years that Dial a Dump owned it Eventually, after a Sydney Morning Herald expose of environmental problems with the site, including that it was  used for illegal dumping of asbestos , the NSW Environmental Protection Authority (EPA)  issued Clean Up notice to remove asbestos from what is known as Stockpile 21 in the south west corner of the site. When Dial a Dump failed to comply with this notice, the EPA extended the notice. The asbestos had still not been removed when Westconnex quietly compulsorily acquired the contaminated site. The landfill site closed and the Clean-Up notice lapsed. Continue reading
