The plans must be implemented until the authorised scheme is decommissioned and reviewed as specified within the plan, following cable burial surveys, or as instructed by the MMO.

(6) In the event that the reports provided to the MMO under sub-paragraph ‎(4) identify a need for additional monitoring, the requirement for any additional monitoring will be agreed with the MMO in writing and implemented as agreed.

(7) In the event that the reports provided to the MMO under sub-paragraph ‎(4) identify impacts which are unanticipated and or beyond those predicted within the Environmental Statement and the Habitats Regulations Assessment, an adaptive management plan to reduce effects to within what was predicted with the Environmental Statement and Habitats Regulations Assessment, unless otherwise agreed in writing by the MMO, must be submitted alongside the monitoring reports submitted under sub-paragraph (4). This plan must be agreed with the MMO in consultation with the relevant statutory nature conservation bodies to reduce effects to an agreed suitable level for the project. Any such agreed and approved adaptive management or mitigation should be implemented and monitored in full to a timetable agreed in writing with the MMO. In the event that this adaptive management or mitigation requires a separate consent, the undertaker shall apply for such consent.
