The East Anglia ONE North Offshore Wind Farm Order 2022

Post construction

22.—(1) The undertaker must, in discharging condition 17(1)(c), submit details (which accord with the in principle monitoring plan) for approval by the MMO in consultation with relevant statutory bodies of proposed post-construction surveys, including methodologies and timings, and a proposed format, content and timings for providing reports on the results. The survey proposals must specify each survey’s objectives and explain how it will assist in either informing a useful and valid comparison with the pre-construction position and/or will enable the validation or otherwise of key predictions in the environmental statement.

(2) The post-construction surveys referred to in sub-paragraph (1) must, unless otherwise agreed with the MMO, have due regard to, but not be limited to, the need to undertake—

(a) appropriate surveys to determine any change in the location, extent and composition of any Sabellaria spinulosa reef identified in the pre-construction survey in the parts of the offshore Order limits in which construction works were carried out. The survey design must be informed by the results of the pre-construction survey;

(b) within twelve months of completion of the licensed activities, one swath-bathymetry survey undertaken to IHO Order 1a standard that meets the requirements of MGN654 and its annexes of the part(s) of the Order limits in which construction works were carried out to assess any changes in bedform topography and such further monitoring or assessment as may be agreed to ensure that cables have been buried or protected;

(c) any marine mammal monitoring required by the monitoring plan submitted in accordance with condition 17(1)(c);

(d) post-construction traffic monitoring in accordance with the outline navigation monitoring strategy, including the provision of reports on the results of that monitoring periodically as requested by the MMO in consultation with Trinity House and the MCA; and

(e) any ornithological monitoring required by the monitoring plan submitted in accordance with condition 17(1)(c).

(3) The undertaker must carry out the surveys agreed under sub-paragraph (1) and provide the agreed reports in the agreed format in accordance with the agreed timetable, unless otherwise agreed in writing with the MMO in consultation with the relevant statutory nature conservation bodies.

(4) Following installation of cables, the cable monitoring plan required under condition 17(1)(d)(ii)(cc) must be updated with the results of the post installation surveys. The plan must be implemented during the operational lifetime of the project and reviewed as specified within the plan, following cable burial surveys, or as instructed by the MMO.
