Installation of Fuel Storage Tanks

By adopting a pragmatic approach REC were able to identify a saving of approximately £1million to the client.

As part of the development of the site, REC have provided validation support to the client and have been overseeing the removal of contaminated materials to appropriate landfill facilities. The validation support has involved the supervision of the remediation process, scheduling of testing, characterisation of materials,and air quality monitoring, with the ultimate aim being the provision of a site suitable for its intended use. The validation report, which is required in order to discharge planning conditions has recently been submitted for approval by the regulators.

Potentially significant ground and groundwater contamination had been identified by consultants acting for the Ministry of Defence around existing fuel storage facilities. A contractor was awarded the contract to reconstruct the facilities and had been advised to set aside £400,000 to bio-remediate soil contaminated by fugitive aviation fuel.

The contractor commissioned REC to quantitatively assess the environmental risk from the fuel contamination. REC modelled the site conditions, applying Environment Agency risk models and advised the contractor that the issue was the movement of volatile hydrocarbons in groundwater, not contamination of soil.

By removing the former tanks and fuel lines, which were the contamination sources and focusing the remedial effort upon remediating the contaminated groundwater, the remedial costs were reduced by over 50%.
