Asda – Chorley
Client: Asda
Hydrogeo were commissioned to provide Environmental Consultancy services during the acquisition, enabling and subsequent redevelopment of the former Texaco Petrol Filling Station, Moor Road Chorley.
The Site’s existing underground petroleum storage tanks comprised 2 no. 70,000 litre, split compartment, double skin tanks located to the east of the Site building with offset fill and supply lines feeding down and across into the forecourt area. The Site had 8 no. additional tanks located towards the western end of the forecourt area; and a set of tanks close to the north-western corner of the Site.
Hydrogeo were advised that in 2000, there was a significant leak of between 20,000 and 25,000ltrs of unleaded petrol from one of the former fuel tanks. The leak occurred from a hole formed through the strike plate and the bottom of the underground tank. The leaking tank was taken out of commission and the site was subsequently remediated with insitu techniques employed by the site owner in order that site could remain operational.
Site investigation works progressed as part of the purchase due diligence indicated the presence of residual Free Phase Product across the site area. Hydrogeo provided a full range of environmental consultancy services in order to successfully satisfy planning conditions assigned to the development. Works progressed by Hydrogeo comprised regulatory liaison, site investigation, controlled waters risk assessment, formulation of a remediation strategy, remediation verification visits and a remediation verification report. All works were completed with the store first opening for business in Summer 2022.
