CIA Cumulative Impact Assessment Acoustic Doppler Current An Acoustic Doppler Current Profiler (ADCP) is a hydroacoustic current meter similar to EIA Environmental Impact Assessment Profiler sonar, used to measure waves and water current velocities over a range of depth. EMP Environmental Management Plan Term used to express the consequence of an impact. The significance of an effect is EMMP Environmental Mitigation and Monitoring Plan Effect determined by correlating the magnitude of the impact with the importance, or ES Environmental Statement sensitivity, of the receptor or resource in accordance with defined significance criteria. MCA Maritime and Coastguard Agency European Union Directive 85/337/EEC, as amended by Directives 97/11/EC, 2003/35/EC EIA Directive and 2009/31/EC and then codified by Directive 2011/92/EU of 13 December 2011 (as MCAA Marine and Coastal Access Act amended in 2014 by Directive 2014/52/EU. META Marine Energy Test Areas A statutory process by which certain planned projects must be assessed before a formal MEW Marine Energy Wales Environmental Impact decision to proceed can be made. It involves the collection and consideration of MHPA Milford Haven Port Authority Assessment (EIA) environmental information, which fulfils the assessment requirements of the EIA Directive and EIA Regulations, including the publication of an Environmental Statement. MHWS Mean High Water Springs Change that is caused by an action; for example, land clearing (action) during construction ML Marine Licence Impact which results in habitat loss (impact). MLW Mean Low Water The META project, located in Pembrokeshire, consists of eight test sites where a MLWS Mean Low Water Springs range of marine energy testing activities will be permitted over a 15 year period. The MOD Ministry of Defence META Project licensing and consenting of the mWave project was originally intended to be undertaken within the consenting and licensing of the META project. mWave will be deployed within NRWa Natural Resources Wales Advisory META Site 8 geographic area. NRW-PS Natural Resources Wales Permitting Services The height of mean high water springs is the average throughout the year (when the PCNPA Pembroke Coast National Park Authority MHWS average maximum declination of the moon is 23.5°) of two successive high waters during SAC Special Area of Conservation those periods of 24 hours when the range of the tide is at its greatest. SPA Special Protection Area The height of the mean low water springs is the average height obtained by the two MLWS successive low waters during the same period as mean high water springs. SSSI Site of Special Scientific Interest A component of the natural or man-made environment that is affected by an impact, SUTU Subsea Umbilical Termination Unit Receptor including people. TCE The Crown Estate A site designation specified in the Habitats Directive (Council Directive 92/43/EEC). Each site is designated for one or more of the habitats and species listed in the Directive. The Special Area of Conservation Directive requires that a management plan be prepared and implemented for each SAC to (SAC) ensure the favourable conservation status of the habitats or species for which it was designated. In combination with SPAs, these sites contribute to the ‘Natura 2000’ or ‘European’ Sites network. A site of European Community importance designated under the Birds Directive (Directive 2009/147/EC), classified for rare and vulnerable birds (as listed on Annex I of the Special Protection Area (SPA) Directive), and for regularly occurring migratory species. SPAs contribute to the Natura 2000 Sites network. Site of Special Scientific Conservation designation denoting a protected area. In England and Wales these sites Interest (SSSI) are identified and protected under the Wildlife and Countryside Act 1981 (as amended). Subsea Umbilical Termination Underwater connection box approx 1.5m2. mWave umbilical and ADCP will connect into Unit unit. Transboundary Crossing into other European Economic Association (EEA) States. mWave Marine Energy Device and Onshore Infrastructure - Environmental Statement Page ii 1. INTRODUCTION 1.2.2 The Project and its location 1.2.2.1 The offshore element of the mWave project comprises a full scale Wave Energy Converter 1.1 Introduction (WEC), mWave, and any agreed navigational markers, a Subsea Umbilical Termination Unit 1.1.1.1 An Environmental Statement has been prepared by Bombora Wave Power Ltd (Bombora) to (SUTU) which connects mWave to an Acoustic Doppler Current Profiler (ADCP) for support the consent/permission for the mWave demonstrator marine energy project and monitoring currents and the marine communication cable up to Mean High Water Springs associated offshore and onshore works. The Environmental Statement accompanies the (MHWS). The onshore works comprise the communication cable from Mean Low Water
