ecological management strategy (OLEMS). The majority of impacts that have been assessed are not significant, however for some receptors locally significant impacts are expected to occur.
98.
Careful route selection has ensured that most designated sites (both statutory and non-statutory) are avoided by the onshore electrical transmission works. The landfall is within the Suffolk Coast and Heaths AONB and the onshore cable route crosses the Deben Estuary Ramsar, SPA and SSSI and Suffolk Coast and Heaths AONB. However, direct impacts upon these sites are avoided by the use of HDD. No impacts are predicted to these sites with the exception of temporary noise disturbance to fauna found within them.
99. Minor adverse impacts are predicted at the landfall and the onshore cable route for woodland scrub, trees and arable land mainly of a temporary nature as a result of disturbance, localised habitat loss and noise. Additionally for coastal habitats, direct habitat loss during the cable installation would lead to a moderate adverse impact on cliffs and slopes dependent upon the construction methodology. With the exception of localised habitat loss (i.e. at the converter station) all habitats would be reinstated after construction.
100. Given the potential changes to the access routes under Scenario 1, the assessment will be updated for the ES and DCO application. However, as new access locations have been selected using existing tracks it is considered that there would be minimal additional receptors affected.
101. Operational impacts would not be significant and would be restricted to maintenance activity impacts at any cable access points (i.e. kiosks) and localised except in the case of a cable failure. It is anticipated that the impacts during decommissioning would be similar those identified for construction although these are likely to be of lower magnitude.
102. Given that that the three proposed East Anglia Offshore Wind projects will not overlap in terms of onshore construction, cumulative impacts are not considered to be greater than those assessed for construction.
30.3.6 Chapter 24 Onshore Ornithology 103. The ornithological interest along the onshore cable route has been identified through desk study and surveys in the bird breeding season and in the winter. Breeding Cetti’s warbler and marsh harrier and non-breeding brent goose, avocet and other waterbirds associated with the Deben Estuary were identified to be the focus of the impact assessment.
