EIA topic
Change in project parameters from PEIR Scenario 1 (as applicable to each topic)
Phasing would mean a longer overall duration for disturbance effects
Operation There is limited need to undertake maintenance of cables therefore limited potential for impact
Decommissioning No change
Key changes in effect/s
Phasing would mean a longer overall duration for disturbance effects (increase of magnitude) None
Likely change in impact significance
changes in magnitude of effect will not change the significance of impacts No change
Comment
Phasing will be discussed in the construction impacts section of the assessment
No change
Onshore Archaeology and Cultural Heritage Construction
Reduced number of pits excavated to house jointing bays
None
There will be lower overall ground disturbance (from excavation pits) therefore a slight decrease in magnitude of effects
Operation Decommissioning
Noise and Vibration Construction
No change No change
None None
No change
Given the limited changes compared to the scale of the proposed project – limited changes in magnitude of effect will not change the significance of impacts. No change
No change
The ES will update the assessment for the revised parameters
Phasing and the number of pits excavated to house jointing bays will be discussed in the construction impacts section of the assessment
Increases in peak daily HGV movements (Single Phase)
Reduction in peak daily HGV movements (Two Phased)
(see Traffic and Transport)
Phase III Report June 2015
East Anglia THREE Offshore Windfarm Page 32
Change (increase or decrease) in magnitude of effect dependent upon approach
Limited changes in magnitude of effect will not change the significance of impacts.
The ES will update the assessment for the revised parameters
Phasing will be discussed in the construction impacts section of the assessment
