19.9 Summary
120. This section summarises the main findings from the impact assessment. This is outlined in Table 19.21.
121. The landfall footprint lies within a statutory designated site (Bawdsey Cliffs SSSI) which could lead to impacts such as loss of sensitive geology through excavation, increased erosion and deterioration of soil quality through spills and leaks. In both scenarios, the potential for degradation of the cliff is considered to be of moderate adverse impact with a high sensitivity. In particular where the SSSI is to be crossed with haul roads and ramps the significance is considered to be moderate adverse. This impact can be reduced to minor adverse following the implementation of suggested mitigation measures.
122. No statutory or non-statutory designated sites are crossed by the cable route, however, the Red Crag present within the eastern half of the onshore cable route (landfall to Tuddenham St Martin) is a reasonably localised stratum and several outcrops in the region are subject to CGS status. The sensitivity of the remainder of the onshore cable route and the converter station is considered to be negligible.
123. There are no soils of significant environmental value identified within the landfall and cable route. The sensitivity of these areas is considered low and the likelihood of direct contamination to soils caused by spillages during construction, following cable installation, is considered to be medium to low magnitude and minor adverse impact.
124. The onshore cable route passes across agricultural land which presents a low risk to the health and safety of construction workers and a number of potential
