Summary
177. A comprehensive and robust impact assessment of the noise impacts likely to arise from the construction, operation, decommissioning of East Anglia THREE have been undertaken. These are summarised in Table 26.32 below. The data and primary analysis makes use of the work undertaken by the proposed East Anglia ONE project. A cumulative impact assessment has been presented which looks at up to three East Anglia Offshore Windfarm projects being developed and considers the impact of the concurrent operation of their onshore project components. In particular three identical converter stations.
178. Some potentially significant impacts have been identified arising from an unmitigated construction works in some locations. However following the implementation of standard mitigation measures these levels can be reduced to a non-significant level.
179. The enduring noise impact from the operation of the project is the noise emissions from the converter station. The converter station is located away from houses and buildings and the operational noise is not considered to be of significant impact. The following predicted impacts for noise and vibration have been identified.
