Dublin's four local authorities would have been landed with a bill for €105M if the Poolbeg Incinerator was stopped from going ahead.
That's what the City Manager has told a panel of politicians at a meeting on the controversial project.
Owen Keegan said he had no choice but to go against Councillors' wishes and give it the go ahead:
"The decision of the Oireachtas, not of me as the Chief Executive, that the power should be mine and the other managers. Given that that power was given to me, I felt that it was absolutely appropriate that I should make what I regarded as the best decision having considered all the information available to me."
