The Council said it made the CPO because of delays in getting a foreshore licence from the Department of the Environment.
But the Irish Waste Management Association's Brendan Keane described the move as 'arrogant and cavalier' and called for a full public hearing by An Bord Pleanála.
Work on the Poolbeg incinerator by US company Covanta ground to a halt when a necessary foreshore licence had not been obtained from the Department of Environment.
The licence is required for the discharge of water used to cool the plant, but by using a CPO for the 2.65 acres the Council can apply directly to An Bord Pleanála and bypass the Department.
In a statement, Assistant Manager Seamus Lyons said the Council made the CPO following a request by its project partners Covanta because of delays in getting the foreshore licence.
He said this licence was applied for two years ago but has not been processed by the Department of the Environment.
Mr Lyons said that the foreshore licence application has not been withdrawn and will run simultaneously with the CPO.
The Department has said that responsibility for foreshore licences was only transferred to Minister John Gormley last January and there is backlog of 700 cases.
