Clay Processing Site, Plymouth
A former clay dryer site where works involved decommissioning, remediation, and restoration of the site.
Works involved the decommissioning and removal of equipment and a number of surplus building structures, pipelines, as well as remediation and restoration of former waste areas, tips, settling tanks, filter beds, and effluent ponds.
Remedial, demolition, and restoration works were undertaken concurrently including testing for naturally occurring radioactive material, as well as asbestos stripping. The restoration process also involved the segregation of old tip materials, which included clay, ash, asbestos, rubble, and scrap metal.
Historical activities on site included informal tipping, as well as settling, drying, and processing of clay. Areas of localised storage of gas oil, diesel and miscellaneous chemicals, localised structures, gate valves, and pipelines that distributed clay sludge and process effluent throughout the site were identified.
Red Rock was commissioned to undertake a number of investigations to determine historical impact by the site’s previous activities, to evaluate contaminant concentrations, potential risks to future re-development of the site and remedial requirements, as well as determination of suitability for re-use of demolition rubble and excavation spoils.
