The development of a wind farm at Derrybrien by Hibernian Wind Power, a subsidiary company of the ESB, is a day to day operational matter for the company and not one in which I have a function. Nonetheless, I understand from Hibernian that, following the occurrence of the bogslide, attention was immediately focused on taking remedial action to minimise the effect of the slide and determining its possible cause.
The construction of wind farm projects is subject to the grant of planning permission under the provisions of the Local Government (Planning and Development) Acts 1963 to 2000. The appropriate local planning authority conducts the planning process for such facilities independently. As part of the planning process, an environmental impact assessment study may also be required in accordance with the provisions of the European Communities (Environmental Impact Assessment) Amendment Regulations 1999. I have no statutory function in regard to the planning aspects of wind energy developments. To be of assistance to the investigation of this incident, the Geological Survey of Ireland, an agency of my Department, in the context of its general scientific interest in landslide occurrences and soil movements, has visited the site and will include information gleaned from that visit in material to be published on its website in due course.
The Shannon Regional Fisheries Board has responsibility for the management, protection and development of the fishery in the Owendalulleegh River and in Lough Cutra, County Galway. I am advised by the regional fisheries board that its initial assessment is that the Owendalulleegh River is seriously damaged from the area of the bogslide near Derrybrien as far as Lough Cutra and that fish are buried in the peat silt deposit. Casualties include stocks of brown trout, eels, etc., of all life stages. The board has indicated that no preventative measures against fish mortality are possible at this stage.
Neither is it possible to assess fully the environmental damage or to estimate the extent of rehabilitation works required until events have fully unfolded. It may be necessary to wait for some months to completely assess the extent of rehabilitation necessary and possible.
The fisheries board has a team of staff working alongside the ESB fisheries conservation unit and environmental staff at Galway County Council in the ongoing assessment of the situation. They are sampling the waters and bed of both river and lake, monitoring for mortalities, assessing the extent of damage to the fish habitat and liaising with other agencies. I understand that all the agencies involved are committed to a restoration and enhancement project on the river when the full extent of the damage has been agreed.
Both the Shannon Regional Fisheries Board and the local authorities have powers to prosecute for the pollution of the river. While the cause is yet to be formally established, the board will investigate the incident further. Should it become clear that there is a responsible party, it is the policy of the board to prosecute.
