Table 3.2 Onshore impact assessment screening EIA topic
Change in project parameters from PEIR Scenario 1 (as applicable to each topic)
Soils, Geology and Ground Condition Construction
There will be no real change from Scenario 1 to Single Phase
Operation There is limited need to undertake maintenance of cables therefore limited potential for impact
Decommissioning
Air Quality Construction
Increased number of excavation pits for jointing pits and increased volume of spoil to be removed from site as a result of Phasing No change
Key changes in effect/s
Likely change in impact significance
Potential small changes in previously assessed areas and volumes
Given the limited changes compared to the overall scale of the proposed works, limited changes in magnitude of effect will not change the significance of impacts
None No change Comment
The ES will update the assessment for the revised parameters
Phasing will be discussed in the construction impacts section of the assessment
No change
Increases in peak daily HGV movements (Single Phase)
Reduction in peak daily HGV movements (Two Phased)
Operation Impact during operation limited to vehicle emissions Decommissioning
(see Traffic and Transport) No change
No change
Phase III Report June 2015
None None No change No change East Anglia THREE Offshore Windfarm Page 29
None
Change (increase or decrease) in magnitude of effect dependent upon approach
No change
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
