The High Court has granted an order closing the country's most complained about landfill.

The Environmental Protection Agency had sought the order before the court to close down the licensed landfill near Naas in Co Kildare.

The landfill in Kerrdiffstown is connected to one of Dublin's largest waste firms, A1 Waste.

The EPA has consistently argued that the landfill, which is run by Neiphin Trading, is causing environmental pollution through the emission of odours.

It is the most complained about landfill with over 200 complaints being lodged with the EPA with many residents claiming that they are vomiting from the odours coming from the site.

Last February the High Court granted an injunction to the EPA to prevent Neiphin Trading from dumping waste in part of its Kerrdiffstown facility.

Today the court heard that since February, the EPA has conducted 11 inspections and found that Neiphin’s sister company, A1 Waste had brought in a further 6,500 tonnes of waste or 260 truck loads onto the site and dumped it illegally in other parts of the facility.

Director of Neiphin Trading and A1 Waste, Tony Dean, denied any environmental pollution had been caused.

He said the company was experiencing severe financial difficulties, losing €100,000 per week because of the previous injunction and the effects of the recession.

He said there was no prospect of the company surviving unless the previous injunction was lifted and the current application for an injunction refused.

Mr Dean warned that if the injunction was granted the company would have to enter into insolvency proceedings, resulting in over one hundred employees being made redundant and 50 contractors.

He warned that the EPA could be left with a bill of €600m to remediate the site if the company went out of business.

Mr Justice Sean Ryan said the situation was extremely serious as there had been breaches of the law in operating the facility.

He refused the company's application to lift the injunction from last February and he granted a further injunction to the EPA to prevent waste from being taken into the site.

Mr Justice Ryan said much of the present problems in the country have come from a failure to adhere to regulations and the consequences of such regulation.

Leaving the High Court, Tony Dean said he would be making no comment on the judgement or what the future holds for the Kerdiffstown site or A1 Waste.
