Dr. Cecil Beamish:

As set out in the Comptroller and Auditor General's report, there is no definitive figure for the total remediation costs. This is because the design of the final remediation of the east tip was dependent on the conditions attached to the EPA licence, the conditions attached by An Bord Pleanála and the foreshore consent. There is ongoing geotechnical work around the east tip to determine the structural basis on which it is sitting and what will be needed to stabilise it. When all of that information, plus the information on where the material that will be used to cap and cover the site can be sourced and the cost thereof, it will then be possible to put together an overall engineering solution. Once that is done, it is the Department's intention to revert to Government with the design solution and its estimated cost.
