Construction monitoring

19.—(1) The licence-holder must, when submitting details of proposed construction monitoring under condition 13(2)(a), include 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) Subject to receipt from the licence-holder of specific proposals pursuant to this condition, it is expected that the construction monitoring will comprise, in outline—

(3) except to the extent agreed in writing by the MMO, measurements of noise generated by the installation of the first four foundations of each discrete foundation type to be constructed under this licence where driven or part-driven pile foundations are used; and

(4) recording of any visual sightings or acoustic detection of marine mammals where required as part of the marine mammal mitigation protocol under condition 13(2)(e).

(5) The results of the initial noise measurements monitored in accordance with paragraph (2)(a) must be provided to the MMO within six weeks of the installation of the first four foundations of each discrete foundation type. The assessment of this report by the MMO shall determine whether any further noise monitoring is required.

(6) Construction monitoring shall include vessel traffic monitoring by Automatic Identification System for the duration of the construction period. A report will be submitted to the MMO and the MCA at the end of each year of the construction period.
