The Environment Agency (EA) and the London Borough of Bromley are to clear a blighted waste site that has been the scene of repeated fires.
They said they would act over the Waste4Fuel site in Orpington because it posed potential environmental and health hazards.
Work will begin when the agency has clarified legal issues with the site’s owner.
Agency area manager Andrew Pearce said: “Work is anticipated to begin this summer on the final clearance of the Waste4Fuel site.
“Those responsible for depositing the waste or profiting from it are being actively pursued through joint EA and police operations. All available powers will be used to bring them to justice and ensure costs are repaid.”
Last month it said it was investigating links between the Waste4Fuel site and matters subject to a police operation elsewhere in the country over alleged waste offences.
Bromley council leader Colin Smith said: “As soon as the EA has managed to resolve their outstanding legal issues, we will be delighted to help find an acceptable resolution which we know would come as extremely welcome news to long-suffering local residents.”
