Design Changes - onshore and intertidal

5

• Selection of final substation location and increase in height of substation structures

• Amendments to cable landfall location and working corridor width in salt marsh

• Realignment of the onshore cable route, inclusion of a section of cable connecting into the NGET substation, an additional cable spur to connect the export cable into the Project substation, and identification of specific working areas and access routes/points

turbines• Increased burial depth for inter-array cables• Changes to location of offshore export cable corridor• Inclusion of 8MW turbine within design envelope (no change in maximum

dimensions of turbines)

Sediment / spoil disposal approach

9

• Insufficient information pre-application to assess impacts of dredging for gravity base / suction caisson foundations

• Approach to disposal within the windfarm site, or at an existing registered disposal site not confirmed

• A range of foundation types to be applied for and assessed in ES – final project design not confirmed, therefore need for dredging and disposal not confirmed

• MMO have approved approach for this to be consented under a separate Marine Licence

Habitat Regulations Assessment

10

• HRA being completed in accordance with Advice Note 10 (January 2013)• HRA Screening & Scoping report issued in October 2012• Consultation ongoing with key stakeholders• Draft HRA Report to be issued SNCBs including SNH, CCW, DoE Northern Ireland,

NPWS Republic of Ireland, Isle of Man, local authorities, RSPB & PINS• Key HRA issues:

Manx shearwater displacement (alone and in-combination with other OWF) Construction impacts on birds using intertidal in Morecambe Bay SPA/Ramsar Construction impacts on saltmarsh habitat from cable landfall works Collision impacts on lesser black-backed gull colonies (Ribble & Alt Estuaries SPA /

Ramsar) - in combination with other Irish Sea zone owf and other plans and projects Assessment of collision impact on migratory whooper swan and pink-footed goose
