The Health and Safety Authority has confirmed it is investigating the site of a new landfill at Knockharley, Navan, Co Meath, after being approached by local people who had been holding daily protests on the main Dublin-Derry road to highlight safety concerns.
Local spokesman Mr Fergal O'Byrne, a Green Party candidate in the local elections, said that the protests were called off after the authority agreed to a request from him to carry out a site investigation.
The protests, which disrupted early-morning commuter traffic on the N2, focused on concerns about the safety of fencing on roads adjacent to construction work on the so-called "superdump", which is being constructed by Greenstar.
The landfill will accept municipal waste from the north east region.
"The outcome of this inspection is that Greenstar and their contractor will have to undertake major boundary fence improvement works starting with the high risk areas along the local county roads," said Mr O'Byrne.
A spokeswoman for the Health and Safety Authority confirmed an investigation was under way and that the developers of the site had been asked to improve boundary fencing.
A Greenstar spokesman said the authority's inspector "did not require the erection of fencing additional to that which is planned.
"However, it was recommended that areas such as public roads and residential property be identified as a matter of priority and that the erection of the permanent fencing be planned for these areas first.
"Greenstar is happy to observe this recommendation," he said.
