Scope overview

The staged capping and closure of completed stages within Green Island Landfill (GILF) is being undertaken, whilst investigations and decisions regarding remaining life are being undertaken. It is likely that complete closure of the whole site will be completed within the next 10 years.

The DCC is seeking a partner to undertake specific staged closure works to the northern area of the GILF which have been filled with waste to final heights in the past 2 years. We need to engage a local and appropriately experienced contractor to undertake the final landfill capping and associated works. The purpose of the works is to:- � Control water ingress. � Reduce leachate generation.

� Provide final contour and stormwater management. � Control gas migration. � Maximise landfill gas generation and ETS returns. � Minimise emissions effects. � Allow plant growth. � Provide physical separation between waste, plant and animal life. � Provide a stable, maintainable long-term landform.
