Mr. Mark Griffin:

A lot of work has been done in the past few years following the closure of historical landfill sites. There are only four or five operational landfill sites in the State now. There was a case at the European Court of Justice, known as Case C-494, which resulted in the State being required to remediate many historical landfill sites, on which we spent approximately €160 million. We wrote to the committee at the end of November, setting out where we were on what are called priority 1 sites. Many such sites are going through various layers of assessment, using a methodology agreed between the Environmental Protection Agency and the local authorities.
