(vi) a mitigation scheme for any features of ecological importance identified by the survey referred to in Condition 13(2)(a);

(e) a marine mammal mitigation protocol, the intention of which is to prevent, amongst other things, injury to marine mammals, primarily auditory injury within the vicinity of any piling, and appropriate monitoring surveys in accordance with the In Principle Monitoring Plan, to be agreed in writing with the MMO in consultation with the relevant statutory nature conservation body;

(f) a cable specification and installation plan following consultation with the relevant statutory nature conservation body, to include—

(i) technical specification of offshore cables, including a desk-based assessment of attenuation of electro-magnetic field strengths, shielding and cable burial depth in accordance with industry good practice;

(ii) a staged cable-laying plan for the Order limits, incorporating a burial risk assessment to ascertain suitable burial depths and cable-laying techniques;

(iii) a cable protection plan providing details of the need, type, sources, quality and installation methods for cable protection; and

(iv) the details of the methodology and extent of post-lay survey, to confirm burial depths; and

(g) a written scheme of archaeological investigation in relation to offshore areas within the Order limits in accordance with Chapter 18 Appendix B of the environmental statement, industry good practice and after discussions with English Heritage to include—

(i) details of the responsibilities of the undertaker, archaeological consultant and contractor;

(ii) a methodology for any further site investigation including any specifications for geophysical, geotechnical and diver- or remotely-operated vehicle investigations;

(iii) within 3 months of any survey being completed, a timetable to be submitted to the MMO setting out the timeframe for analysis and reporting of survey data;

(iv) delivery of any mitigation including, where necessary, archaeological exclusion zones;

(v) monitoring during and post-construction, including a conservation programme for finds;

(vi) archiving of archaeological material including ensuring that a copy of any agreed archaeological report is deposited with the English Heritage archive by submitting an English Heritage OASIS form with a digital copy of the report; and

(vii) a reporting and recording protocol, including reporting of any wreck or wreck material during construction, operation and decommissioning of the authorised scheme; and
