Controversial plans to build a waste incinerator at Poolbeg in Dublin may be abandoned by Dublin City Council.
City manager Owen Keegan said the project may be dropped even if it survives EU scrutiny.
Mr Keegan said the decision on whether to proceed with the Waste to Energy project would be made after the EU's investigation into two complaints about the project.
The complaints made to the EU investigation claim that the public-private partnership contract with the company Covanta breached EU regulations on state aid and procurement.
The manager declared the complaints were due to be decided before the end of March, but little progress has been made.
If the project emerges "unscathed" from this investigation, a report will be given to councillors outlining the options available, he said at the council's monthly meeting last night.
Mr Keegan confirmed at the meeting that the contract with consultants RPS would be terminated by January 31.
The EU has already upheld a complaint that the contract with RPS did not conform to procurement guidelines.
The RPS contract was originally estimated at €8m but cost over €30m as the project encountered a series of delays lasting 10 years.
Several councillors complained about the huge overrun and demanded explanations on how it happened.
The Poolbeg incinerator project has already cost more than €90m without any building work on the site.
