The Government has published a list of the first departments to be decentralised out of Dublin.
It is planned for nearly 3,500 civil servants from 15 Government departments to relocate to 20 locations by 2008.
These findings were published in the latest report of the decentralisation implementation group, chaired by Phil Flynn.
The Minister for Finance, Brian Cowen, said it has been shown that there is substantial interest in the programme among civil and public servants and that implementation of the programme is well on track.
However, Fine Gael Finance Spokesperson Richard Bruton said the scale and timing of the decentralisation programme is in tatters.
Mr Bruton said the promises made by the Minister for Finance in last year's Budget concerning decentralisation had now unravelled.
It has also been revealed that it would take over 20 years to break even on the cost of decentralisation.
2,130 civil servants who are among the first to be decentralised will have six deadlines for moving out of the capital.
The first wave will include moving the headquarters of both the Department of Social & Family Affairs and the Department of Communications, Marine & Natural Resources to Drogheda in Co Louth.
Social & Family Affairs will also move 100 staff to Sligo, while Communications, Marine & Natural Resources will move 91 staff to Clonakilty in Co Cork.
The Department of Arts, Sport & Tourism headquarters will move to Killarney in Co Kerry.
The Revenue Commissioners will move 150 staff to Kilrush in Co Clare, Listowel in Co Kerry and Newcastlewest in Co Limerick. Each location will get 50 staff.
The Department of Foreign Affairs will relocate 125 staff to Limerick, while the Irish Prison Service headquarters will move 159 staff to Longford.
The Department of Transport is moving 40 staff to Loughrea in Co Galway, and the Department of Defence headquarters, with its 202 staff, will move to Newbridge in Co Kildare.
The Department of Agriculture is relocating 392 staff to Portlaoise in Co Laois.
The Office of Public Works headquarters will also be in the first wave of transfers, with 333 staff moving to Trim in Co Meath.
Finally, the Department of Finance is moving 135 staff to Tullamore in Co Offaly.
