Commercial redevelopment of a former service station into a fast food outlet in Kent.
23 March 2011, News release from Ecologia Environmental Solutions Ltd
With the re-development of a former service station Ecologia has demonstrated its ability to provide a complete contaminated land solution for its clients to a fixed pre-agreed budget and on time.
The Former Service Station occupies an area of approximately 1000 m2 located within a small commercial site in Kent.
The site was used as a petrol station between 1958 and 1996.The main buildings on site were subsequently demolished and the underground fuel storage tanks (USTs) sealed or decommissioned.
Ecologia won the contract to act as the Principal Contractor and remediate the site to an appropriate standard to enable construction of a new fast food retail outlet. Works were to include removal of the remaining underground fuel storage tanks and treatment of the soils to a suitable criteria deemed protective of human health.
Ecologia proposed to undertake remediation works on the site by adapting the existing methodology and further refining the quantitative risk assessment in order to comply with current best practice guidelines. This provided our client with a significantly reduced remediation cost and timescale. Ecologia's methodology also included the implementation of a Materials Management Plan (MMP) under the new CL:AIRE code of practice.
The site was included as a 'cluster' site under a wider hub and cluster scheme operated by Ecologia in Kent, thus reducing the quantities of material requiring off site disposal. Under this scheme crushed concrete from a nearby site was also imported to the site in order to build a suitable access road.
Validation soil sampling was undertaken in the excavated area, following treatment with an oxygen release compound. Results of the soils analysis demonstrated that all hydrocarbon contaminated soils had been removed from the tank farm area. The analysis also showed that the stockpiled impacted soils had been successfully treated with oxygen release compounds and these were deemed suitable for re-use on site to backfill excavated areas. Excess stockpiled soils were disposed of off site as inert or non-hazardous waste.
Boreholes were also drilled and installed as monitoring wells by our internal drilling division to facilitate groundwater monitoring to assess potential offsite migration of contaminants. A validation remediation report was compiled by Ecologia following completion of the work on site. The report was submitted to the Local Authority and Environment Agency for their review and comment to complete the project.
Favourable replies were received by both regulatory authorities, allowing the Client to progress with the second phase of the works. The Project was completed on time by Ecologia within the terms of our fixed price contract
