167. The mitigation measures outlined for the construction of the cable route and converter stations, for the control of noise, would therefore also be expected to be adopted for the decommissioning phase.


Cumulative Impacts


168. This section describes the cumulative impact assessment for noise, taking into consideration other plans, projects and activities.


169. In its simplest form, the cumulative impact assessment strategy involves consideration of whether impacts on a receptor can occur on a cumulative basis between East Anglia ONE, East Anglia THREE and East Anglia FOUR and other activities, projects and plans for which sufficient information regarding location and scale exist.


170. As each project will be constructed at different times and are not anticipated to be constructed concurrently there is no opportunity for cumulative construction impacts to occur between the East Anglia ONE, East Anglia THREE or East Anglia FOUR


Table 26.28 Potential cumulative impacts Impact


Scenario 1: Open Trenching construction


Scenario 2: Pre-installed Ducts construction


Operation No No Yes


Potential for cumulative impact


Data confidence Rationale Medium Medium High


Projects have distinct and separated timetables


Projects have distinct and separated timetables


Operational noise impact of East Anglia ONE, THREE and FOUR converter stations operating concurrently.


Decommissioning No High


Assume East Anglia ONE, THREE and FOUR are decommissioned at different times
