Comment
We advise that the assessment of the potential for Annex I sandbank and any potential impacts should be explicitly presented within the ES.
November 2012
When designing surveys we advise that grab sample and video / still imagery sampling sites are located with reference to geophysical data. The use of previously collected remote sensing data makes for effective benthic ecology survey as it enables better direct sampling effort.
Response / where addressed in the PEIR
No Annex I sandbanks have been identified within the proposed project boundaries
The design of the East Anglia THREE and FOUR offshore cable corridor survey used the geophysical surveys to assign sampling sites (see Appendix 10.4 for details)

We also advise that geophysical data collected in areas of potential Annex I habitat is undertaken such that it enables a meaningful estimate of the coverage of the potential Annex I habitat in the area and to be effected as a result of development.
Geophysical surveys have been conducted across the entire zone as well as hi resolution site specific surveys. The results of which have been used to identify areas that potentially support Annex I habitat (Appendix 10.2 Appendix 10.3 and Appendix 10.4)

If there is any scoping out of impacts to Annex 1 habitats it should be explicitly explained why.
Impacts are not scoped out although in the event of Annex I habitats being present during pre- construction surveys, micro-siting would ensure impacts are minimised or avoided.

Full details of scour quantity need to be assessed in the ES to ensure the footprint is accurate.
Appendix 7.3makes an assessment of scour protection.
