Underground Storage Tank Removal, Osborne Park

Projects>>Underground Storage Tank Removal, Osborne Park

The Site

Located in Osborne Park this site had been location of a large well-known home décor shop for many years. The shop and store rooms were contained within a large warehouse with concrete flooring while the external area consisted of a bitumised car park.  The site owner was not aware that an underground tank was on site and was only made aware of its presence when HRS attended the site on other matters.

The Issue

The site owner was intending to sell the property and, when selling a property, according to the Contaminated Sites Act 2003, the owner must declare the presence of any underground storage tanks or systems to purchasers. This is because underground petroleum storage tanks/systems, particularly older-style tanks, present a potential pollutant risk to the owner of the site. Purchasers must be aware of the presence of the tank and thereby be informed of the risk as they may be deemed liable for any pollution found on a property they own.

The Job

HRS was contracted by the current site owner to remove the underground storage tank. HRS performed background investigations to determine any information pertaining to the tank prior to removal and found a 10 kL tank had been installed over 20 years ago. HRS coordinated the excavation of the soils surrounding the tank, had the tank lifted from the pit and placed onto a licensed carrier for transport and disposal and validated the remaining soils. The pit was backfilled with clean-fill materials and resurfaced.

The Outcome

HRS submitted our report on the tank removal to the Department of Mines and Petroleum who have since closed the dangerous goods storage file against the property.
