Both the EIA Directive 85/337/EEC, as amended, and Directive 96/61/EC concerning integrated pollution prevention and control, IPPC, require transboundary consultation where a project is likely to have significant environmental effects in another member state. These requirements have been transposed through the Planning and Development Act 2000 and associated regulations, the Environmental Protection Agency Act 1992 and associated regulations and the Waste Management Act 1996 and associated regulations.
Primary responsibility for the carrying out of transboundary consultation under these provisions rests with the planning authority, or An Bord Pleanála in the event of an appeal, in the case of planning consent requirements and the Environmental Protection Agency in the case of an IPPC or waste licence requirements.
