Environmental campaigners have spoken of their shock at lack of government intervention at an illegal ‘super dump’ on the outskirts of Derry.
The dump at Mobouy Road - the focus of a BBC NI Spotlight investigation aired last night - was discovered last year.
Friends of the Earth say the Department of Environment knew about unauthorised quarrying at the site as far back as 2000 but failed to take any action.
James Orr, Director, Friends of the Earth Northern Ireland said :“It’s upsetting to think Northern Ireland is the best in Europe at illegal dumping.
“What is more shocking about this case is that the government knew about this monster dump for years and did nothing.
“Time and time again, no-one seems to be held to account.”
“The government has again failed to get its act together and the waste industry must come clean.
“The widespread nature of unlawful dumping and other evidence demands a judge-led investigation into the murky world of the waste industry.”
Last June, the then Environment Minister Alex Attwood revoked the licence of City Industrial Waste as part of the Northern Ireland Environmental Agency investigation into the discovery of the 516,000 tonnes of illegal waste at Mobouy Road.
In December 2013, an independent report from Chris Mills, the former Director of the Welsh Environment Agency, described the dumping at Mobouy as “a sophisticated operation which had been carried out over a number of years”.
He said it had “the hallmarks of organised crime involvement”.
A spokesman for the Department of the Environment said a file was being prepared for the Public Prosecution Service.
