The sentencing of the retired director of a waste management company who was convicted over the illegal operation of a landfill site in Co Kildare has been deferred at Dublin Circuit Criminal Court.

Mr Barry White SC said his client, 70 year-old Tony Dean from Woodhaven, Milltown in Dublin, had not yet had heart surgery for a medical condition outlined at the last hearing, but he understood it would be three to four weeks before this would take place.

Prosecuting counsel said they had no objection and the case was put back for mention again on Thursday 30 March, when a date for sentencing will be set by Judge Melanie Greally.

Tony Dean was found guilty by a jury in November of offences contrary to the Waste Management Act 1996.

He had pleaded not guilty to two charges that he, as then director of Nephin Trading Ltd, disposed of or undertook the recovery of waste at a facility in Kerdiffstown, Naas, Co Kildare, otherwise than in accordance with the waste licence then in force between October 2003 to September 2006 and separately between September 2006 and November 2008.

He had also denied a third charge that he held or recovered waste in a manner likely to cause environmental pollution at the Kerdiffstown site between October 2003 and November 2008.

The jury returned guilty verdicts on all three charges against him in November 2022.

At a sentence hearing in December, the prosecution said waste in the northwest part of the facility at Kerdiffstown had reached a height of 116 metres above sea level by 2008, and that this had resulted in a number of environmental risks, including the build-up of gas, leachate and odours.

Fifty cubic metres of leachate had been produced from the site per day over the period concerned and was slowly making its way into the surrounding geology.

There were also 188 complaints about odours from the site at this time.

At the time, Mr Dean had been director of Nephin Trading Limited which operated the facility until it ceased to accept waste in June 2010.
