Summary

Lean Quarry Landfill Site is a modern site, engineered to standards set by the Landfill Directive. The site was developed from 2003 onwards by Viridor.

History

Lean Quarry landfill was granted planning permission in 2002 by Cornwall County Council. At the time, the site was owned and operated by Roseland Plant Hire Limited who were acquired by Viridor later in 2002. An environmental permit for the site was granted in 2003 and construction of the site commenced thereafter.

Geology

The quarry is excavated into Devonian and Carboniferous deposits comprising basalt pillow lavas extruded on to slate and siltstone country rocks. The basaltic rocks are known as dolerite locally, although this is incorrect nomenclature. These are defined by the Environment Agency as a Secondary Aquifer, although due to the lithology, locally they are not water-bearing to any significant degree.

Engineering and Environmental Controls

Thelandfill is constructed as a Containment Facility, utilizing the re-worked siltstone and slate derived clay materials as the principal barrier. The landfill lining system is augmented with a flexible membrane liner of High Density Polyethylene (HDPE) on the base and the lower part of the sidewalls. The sidewalls are steeply graded and required buttressing to enable construction within the 40+ metre deep quarry.

There is Landfill Gas power generation with electricity export to the National Grid. Installed capacity is 2.05MW.

Viridor have been unable to secure a connection to the local sewerage system, principally due to a lack of local treatment capacity at the receiving Sewage Treatment Works. Consequently, Leachate produced by the site is removed by tanker to appropriately permitted Sewage Treatment Works.

Other Infrastructure

Elsewhere within the quarry complex, Viridor also developed a Materials Recovery Facility to deal with locally derived recyclable waste streams. This facility was covered by the same planning consent as the landfill.
