The DNSDC Refuelling Area Remediation project was a $2.3 million dollar site remediation project involving the demolition of existing superstructure such as buildings and canopy and the removal of all existing Underground Petroleum Storage System infrastructure, including all bowser pumps, associated pipework, one 65,000 litre and five 55,000 litre storage tanks with associated fittings and supply lines.
Associated with the deconstruction and UPSS removal was the removal of asbestos pipes and quantities of contaminated soils.
OPEC Systems engaged Liberty Industrial to carry out the demolition of the canopy and office/amenities building prior to the removal of underground storage tanks which were cleaned and degassed on site. The team moved rapidly to excavate and stockpile potentially contaminated soils in conjunction with Defence’s Environmental Consultant GHD.
To reduce the straight ‘dig and dump’ landfill option for contaminated soils, a new sustainable solution for the contaminated soils was provided whereby the soils are transported to a specialist waste facility for processing by intensive bioremediation.
