Marine Current Turbines Ltd have constructed the first tidal power turbine in the UK off the coast of Devon, which has been in operation for over two years. A second, larger turbine to be known as “Seagen” is proposed in order to further develop this technology through investigation of its engineering, management systems and environmental impacts. This Environmental Statement has been prepared in support of Marine Current Turbine Ltd’s application to construct Seagen under the Food and Environment Protection Act (1985) in accordance with recognised environmental impact assessment procedures. The assessment involves the application of a standardised process to identify the likely impacts from all relevant issues identified through an initial scoping process and wider consultation with regulators, non-governmental organisations and other interested parties. As the proposed location falls within an area protected under domestic and European law, information considered relevant to a further ‘appropriate assessment’ process has been collected or collated from other sources in order to assist the Environment and Heritage Service as ‘Competent Authority’ in determining if the project is unlikely to damage the protected features.
