91.
Scenario 2 – installing trenches and ducts
Construction of onshore cable systems including landfall joint transition bay and 61 cable jointing locations – installation techniques digging trenches and installing ducts for the proposed East Anglia FOUR project, and undertaking HDD activities;
Construction of an onshore converter station, associated infrastructure and landscaping;
Creation of temporary construction compounds / HDD compounds;
Temporary upgrade of existing access tracks, construction of new access tracks and haul roads;
Stockpiling of topsoil and subsoil; Re-use of excavated soil in trenches; Disposal of excess spoil offsite to a suitably licenced facility; and Removal and reinstatement of existing drainage systems.
92. A CoCP will include the embedded mitigation, an example of which is provided in Appendix 5.1. The following section takes into account embedded mitigation and any other mitigation measures suggested within the section are additional.
93. Two different construction scenarios (as outlined in section 22.3 and Chapter 5
Description of the Development) are being considered for the onshore cable installation. These scenarios are considered separately, or grouped where there is considered to be no difference in impact between the different scenarios.
94. Note that for the purposes of this PEIR, EATL have assessed the impacts in most cases without reference to exact footprints (i.e. area). For the final ES in the DCO submission EATL intend to refine the assessment with more information on footprints (for example onshore electrical transmission works and access) where possible.
22.6.1 Potential Impacts during Construction

activities and effectively taken out of use. Due to health, safety and technical requirements during construction, works areas would be fenced off and not accessible to landowners or occupiers for the duration of the construction period. This could result in loss of growing season of area affected for each farmer (plus possible severance) and loss of income which would be addressed via commercial agreement.
