reinstatement of the current land use at the site, it is anticipated that the impacts would be similar those during construction, these impacts are listed in Table 21.18.
21.7 Cumulative Impacts
122. Potential cumulative impacts to groundwater and surface water could arise from interaction with other developments within the vicinity of East Anglia THREE either temporally or spatially. With regards to the potential impact to water resources and quality cumulative impacts consideration should be given to projects located within the same groundwater and surface water catchments. However, given that the majority of the potential impacts to water resources and flooding with regards to the onshore electrical transmission works are of a temporary nature, the cumulative impact assessment should only consider developments are likely to have significant impacts during a similar period as this development. With regard to the receptors assessed in this chapter a potential for cumulative impact would only occur if those same receptors are affected. Whilst there may be additive cumulative impacts at the wider regional scale (e.g. several developments may affect the same drainage systems may be affected) these activities would be managed and mitigated in a similar way to impacts described above for East Anglia THREE and there would be few impacts.
123. A full list of projects that have been scoped into the cumulative impact assessment is provided in Table 21.16. These cover major known developments in the vicinity of the onshore electrical transmission works. The two key projects which have been identified as potentially causing cumulative impacts are the proposed East Anglia ONE and East Anglia FOUR projects which share the landfall and onshore cable route with the proposed East Anglia THREE project. These projects also propose to locate converter stations within close proximity of the converter station proposed for East Anglia THREE.
