EIA topic
Change in project parameters from PEIR Scenario 1 (as applicable to each topic)
Water Resources and Flood Risk Construction
There will be no real change from Scenario 1 to Single Phase
Increased number of excavation pits for jointing pits and increased volume of spoil to be removed from site.
Increased footprint of substation area
Operation There is limited need to undertake maintenance of cables therefore limited potential for impact
Decommissioning
Land Use Construction
Increased number of excavation pits for jointing pits and increased volume of spoil to be removed from site No change
Key changes in effect/s
Likely change in impact significance
Comment
Potential small changes to groundwater would be minor and short term. No changes to surface water
Potential small changes to flood risk assessment
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
The ES will update the assessment for the revised parameters
Phasing will be discussed in the construction impacts section of the assessment
None
No change
No change
There will be no real change from Scenario 1 to Single Phase approach.
None
Potential small changes in previously assessed areas and volumes
No change
Given the limited changes compared to the overall scale of the proposed works, limited changes in magnitude of effect
