(b) a Phase 1 survey of the intertidal area within which it is proposed to carry out construction works;

(c) a high resolution swath bathymetric survey to include a 100% coverage and a side scan sonar survey of the part(s) of the offshore Order limits within which it is proposed to carry out construction works and disposal activities under this licence, including a 500m buffer around the site of each works; and

(d) a grab survey and particle size analysis in the part(s) of the offshore Order limits within which it is proposed to carry out dredging and disposal activities relating to Works Nos. 5 and 6 under this licence within a period not longer than 12 months prior to the dredging and disposal activities, to determine the extent of suitable herring spawning habitat within areas HU209 and HU210.

Construction monitoring E+W+S

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—

(a) 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 comprised in Work No. 4 to be constructed under this licence where driven or part-driven pile foundations are used; and

(b) 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).

(3) 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.

(4) 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.

Post construction E+W+S

20.—(1) The licence-holder must, when submitting details of proposed post-construction surveys, include methodologies and timings, and a proposed format, content and timings for providing reports on the results. The survey proposals shall 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 of specific proposals, it is expected that the post-construction surveys will comprise, in outline—

(a) a survey to determine any change in the location, extent and composition of any benthic habitats of conservation, ecological and/or economic importance identified in the pre-construction survey in the part(s) of the offshore Order limits in which construction works were carried out. The survey design will be informed by the results of the pre-construction benthic survey;

(b) one high resolution swath bathymetric survey to be undertaken no sooner than six months following completion of construction works and disposal activities to include a 100% coverage of the part(s) of the offshore Order limits with a water depth no greater than 12 metres (referenced to Chart Datum) within which construction works and disposal activities were carried out under this licence to assess any changes in bedform morphology and such further monitoring as may be required to ensure that the cables have been buried or protected and sediment is able to move over any installed cable protection. The need for further surveys will be agreed in writing with the MMO following submission of the first year of survey data;

(c) a grab survey and particle size analysis in the part(s) of the offshore Order limits within which dredging and disposal activities relating to Works Nos. 5 and 6 were carried out under this licence within 12 months of the completion of the dredging and disposal activities to determine the extent of suitable herring spawning ground habitat within areas HU209 and HU210;

(d) vessel traffic monitoring by Automatic Identification System, for 28 days taking account seasonal variations in traffic patterns, for a maximum duration of one year post construction. A report will be submitted to the MMO and the MCA at the end of the first year after construction is completed; and

(e) one high resolution bathymetric survey of a representative sample area, to be agreed in writing with the MMO, of the part(s) of the offshore Order limits with a water depth no greater than 12 metres (referenced to Chart Datum) within which construction works and disposal activities were carried out under this licence following the first major storm event the timing of which shall be agreed with the MMO in consultation with Natural England and the Environment Agency.

Offshore Decommissioning E+W+S

21.  No decommissioning activities shall commence until plans for the carrying out of such activities have been submitted to and approved in writing by the MMO.

Restrictions in intertidal area and Humber Estuary Special Area of Conservation E+W+S

22.—(1) The cable protection to be used within the Humber Estuary Special Area of Conservation must be frond mattressing, except to the extent agreed in writing with the MMO.

(2) No cable protection is to be used within the intertidal area of the Humber Estuary Special Area of Conservation.

(3) The licence-holder must not construct or install those licensable activities comprised in Work No. 6 or Work No. 7 in the intertidal area between 1st October and 31st March (inclusive) except to the extent agreed in writing with the MMO, in consultation with Natural England.

(4) In the event that the MMO notifies the licence-holder that other works are planned to take place in the intertidal area comprised within the offshore Order limits or within the area whose co-ordinates are set out in Table 8, the licence-holder must not construct or install those licensable activities comprised in Work Nos. 6 and 7 within one kilometre seaward of the seawall during the period of time commencing two hours before a high tide greater than 7.7 metres (as measured at Grimsby) and ending two hours after a high tide greater than 7.7 metres (as measured at Grimsby) between 1st April and 31st May (inclusive) and 1st August to 30th September (inclusive), except to the extent approved in writing by the MMO, in consultation with Natural England.

Amendments to details E+W+S

23.—(1) With respect to any condition of this licence which requires the licensed activities to be carried out in accordance with the plans and programmes approved by the MMO, the approved plans and programmes shall be taken to include any amendments that may subsequently be approved in writing by the MMO.

(2) Where the words ‘except to the extent agreed in writing by the MMO’ appear in these licence conditions, any such agreement or statement may only be given in relation to immaterial changes where it has been demonstrated to the satisfaction of MMO that the subject matter of the agreement sought is unlikely to give rise to any materially new or materially different environmental effects from those assessed in the environmental statement.
