Ducts A duct is a length of underground piping, which is used to house electrical and communication cables. Evidence Plan Process A voluntary consultation process with specialist stakeholders to agree the approach to the EIA and information to support the HRA. Jointing pit Underground structures constructed at regular intervals along the onshore cable route to join sections of cable and facilitate installation of the cables into the buried ducts. Landfall Where the offshore cables come ashore at Happisburgh South. Landfall compound Compound at landfall within which HDD drilling would take place. Mobilisation area Areas approx. 100 x 100m used as access points to the running track for duct installation. Required to store equipment and provide welfare facilities. Located adjacent to the onshore cable route, accessible from local highways network suitable for the delivery of heavy and oversized materials and equipment. National Grid new / New overhead line towers to be installed at the National Grid substation. replacement overhead line tower National Grid overhead line The works to be undertaken to complete the necessary modification to the modifications existing 400kV overhead lines. National Grid substation The permanent footprint of the National Grid substation extension. extension National Grid temporary Land adjacent to the Necton National Grid substation which would be works area temporarily required during construction of the National Grid substation extension. Environmental Statement Norfolk Boreas Offshore Wind Farm June 2019 Page iv Necton National Grid The grid connection location for Norfolk Boreas and Norfolk Vanguard substation Onshore 400kV cable route Buried high-voltage cables linking the onshore project substation to the Necton National Grid substation. Onshore cables The cables which take power and communications from landfall to the onshore project substation. Onshore cable route The up to 35m working width within a 45m wide corridor which will contain the buried export cables as well as the temporary running track, topsoil storage and excavated material during construction. Onshore infrastructure The combined name for all onshore infrastructure associated with the project from landfall to grid connection. Onshore project area The area of the onshore infrastructure (landfall, onshore cable route, accesses, trenchless crossing zones and mobilisation areas; onshore project substation and extension to the Necton National Grid substation and overhead line modifications). Onshore project substation A compound containing electrical equipment to enable connection to the National Grid. The substation will convert the exported power from HVDC to HVAC, to 400kV (grid voltage). This also contains equipment to help maintain stable grid voltage. Running track The track along the onshore cable route which the construction traffic would use to access workfronts. The Applicant Norfolk Boreas Limited The project Norfolk Boreas Wind Farm including the onshore and offshore infrastructure. Transition pit Underground structures that house the joints between the offshore export cables and the onshore cables Trenchless crossing Pairs of compounds at each trenchless crossing zone to allow boring to take compound place from either side of the crossing. Trenchless crossing zone Areas within the onshore cable route which will house trenchless crossing entry (e.g. HDD) and exit points. Workfront A length of onshore cable route within which duct installation works will occur, approximately 150m. Environmental Statement Norfolk Boreas Offshore Wind Farm June 2019 Page v 1 Introduction Consultation is a key driver of the Environmental Impact Assessment (EIA) process, and throughout the lifecycle of the project, from the initial stages through to consent and post-consent. As the Norfolk Boreas and Norfolk Vanguard projects are sister projects due to the proposed strategic development of both projects, much of the consultation undertaken as part of the Norfolk Vanguard Evidence Plan Process (EPP) is also relevant to the Norfolk Boreas project. Such consultation has directly influenced the Norfolk Boreas project and has been taken into consideration and integrated into the impact assessment for Norfolk Boreas. In addition, information submitted as part of the Norfolk Vanguard examination, up to Deadline 5 (20th March 2019), has also been considered where relevant. This appendix contains the results of the Norfolk Vanguard consulation and examination which have been used to inform the Norfolk Boreas assessment. 2 Consultation responses Norfolk Vanguard Table 2.1 summarises the consultation that has been undertaken for Norfolk Vanguard that is relevant to and has informed the development of Chapter 23 Onshore Ornithology of the Norfolk Boreas ES and provides details of how it has been taken into consideration.

However, we accept that there is assessment (section limited value in a second year of winter 23.7 and 23.8). surveys if the presence of geese and swans will be determined by the crop regime. We therefore advise that together with any survey and/or WeBS data, information about predicted crop patterns at the time of the proposed work are taken into account.
