The lagoons, on a former colliery tip next to Grassmoor Country Park contain tar and contaminated liquid from the former Avenue Coke Works run by British Coal.
We secured the funding for the work from the Government’s Department of Energy and Climate Change and East Midlands Development Agency.
The work to remove the toxins and restore the site to woodland, which will be opened up to the public as part of the surrounding park, will be managed by RemedX of Derby.
Detailed environmental assessments of the site and surrounding area will be carried out and the views of local residents and park users sought on the proposals.
We will submit a planning application for the work in February 2010 and we will also need approval from the Environment Agency before the decontamination process can start.
We expect to open the restored area to the public in 2014. We will publicise further details of the plans over the coming months.
