Indaver Ireland has confirmed that it has submitted additional information to An Bord Pleanála in relation to its application for a €160 million incinerator at Ringaskiddy, Co Cork.
A decision on the project by An Bord Pleanála has already been postponed three times.
Indaver has now submitted corrected copies of two appendices to its Environmental Impact Statement, along with an explanation of how what it describes as an "administrative error" occurred, which meant incorrect information was previously submitted.
Indaver insists that the conclusions of its EIS are unchanged.
Indaver has also responded to concerns raised by the Department of Defence relating to the impact of the proposed incinerator on helicopter traffic at the adjoining base of the Naval Service.
It says a number of experts which the company consulted have concluded that the incinerator will not curtail, constrain or affect the safety of helicopter operations at the base.
Indaver Ireland Managing Director John Ahern said the company is confident its proposed incinerator is fully in line with regional, national and EU waste policy and that the need for such a facility in Cork is underlined by the fact that most of Cork's residual waste is exported to elsewhere in the country or abroad.
Indaver is applying for a licence for an incinerator capable of dealing with 240,000 tonnes of waste per annum.
The facility proposes to incinerate household, commercial, industrial, non-hazardous and suitable hazardous waste.
It says the facility will generate approximately 18.5mw of electricity in the process.
