RAAF Amberley

As part of the $348M spend for the EA-18G Growler upgrade at RAAF Amberley, WestRex Services was able to help with the final fate of contaminated soil from the site.  The soil, which is contaminated with PFAS from past activities carried out on site, was moved both under the Soil Disposal Permit system and Waste Tracking Certificates as a regulated waste.  The soil was deemed to be acceptable for disposal to the TiTree Bioenergy Facility.

A total of close to 6100 tonne of contaminated soil was moved and disposed of during April.  A further 1300 tonne of PFAS contaminated concrete was also disposed of at TiTree, which was a solution provided by WestRex for last loads of the day for concrete, as the Swanbank Facility could not receive after 3pm.

In all, there are over 40 tenders that have been released by Lend Lease for the construction of this facility and this particular civil works package was given to Pensar.  WestRex will see further contaminated soil come from this project for future disposal through Pensar and also through Piping Solutions who have been awarded the fuel line portion of the project.

The Growler project has an estimated completion date of 2023.

Hazardous Waste, Some Unknown

When an upcoming audit was due to be conducted on site, the client turned to WestRex for assistance. The prior tenant had stockpiled a large amount of hazardous waste, some waste unknown, and needed this taken off site within two days.   WestRex personnel arrived on site with only a day’s notification to commence consolidating scattered drums from across the site.   Once inductions were done, WestRex Personnel were busy triaging and sorting various drums.

Part way through the triaging process, the client announced they had another abandoned site they needed drums to be taken from and so WestRex went to take a look.   These drums where then sent back to the main site in Roma to be consolidated with the drummed waste on site for treatment and disposal.

The project was completed within two days by three WestRex personnel which included WestRex’s qualified Chemist.   The amount of waste consolidated and sent for treatment was:

  • 6 car batteries
  • 44x205L drums of Oily rags and filters
  • 16x205L drums of waste oil
  • 50x 205L empty drums with residues
  • 200x 20L empty drums with residue
  • 40x 1000L IBC’s of waste engine oil

The environmental outcomes for this waste included:

  • Recycling of the used engine oil,
  • Recycling of the lead acid car batteries,
  • Reuse of the empty 205L drums.

The two waste streams that could not be recovered were the oily rags and filters and the empty 20L drums which were immobilised and sent to a controlled landfill.
