[holding answer 4 February 2009]: In the construction of the Olympic Park, the Olympic Delivery Authority (ODA) will transform a previously contaminated site into an integral part of the long-term regeneration of east London and the wider Thames Gateway. Across the whole site the ODA continues to exceed its 90 per cent. target of reclaiming demolition material for reuse or recycling.
Where possible, all excavation and demolition waste from the Olympic stadium site is treated at source and the cleansed material, where appropriate, reused or recycled in the landscaping and foundations work of the Olympic Park.
Where this has not been possible, waste material has been transported off-site for landfill disposal at Environment Agency approved sites across the UK. The locations of those sites are:
Kings Cliff, Cambridgeshire (Augean Kings Cliff)
Dudley, West Midlands (Himley Quarry)
Teesside, North Yorkshire (Impetus Waste Management ICI 3)
Barling Magna, Essex (Barling Landfill)
Purton, North Wiltshire (Parkgate Farm Landfill)
Middlesbrough, Cleveland (Augean Middlesbrough)
In addition, a small amount of arisings from the stadium site were identified in summer 2008 as containing—or potentially containing—asbestos above the agreed levels. This waste was taken off-site for safe disposal to Powerday landfill facilities at Old Oak Sidings in London.
