(g) cable specification and installation plan in accordance with the methodology assessed in the environmental statement, to include—

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

(ii) a detailed cable laying plan for the Order limits seaward of MHWS, incorporating geotechnical data and a cable burial risk assessment to inform cable burial depths and cable laying techniques, including contingency measures, in the event cable burial is not achieved by the methods proposed in that plan;

(h) a written scheme of archaeological investigation in relation to the Order limits in accordance with industry good practice and developed in consultation with English Heritage, and where applicable, the relevant local authority, to include—

(i) details of 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) a programme for the analysis and reporting of survey data, and timing, which is to be submitted to the MMO within four months of the survey being completed, unless otherwise agreed with the MMO;

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

(v) details of monitoring during and post construction, including a conservation programme for finds and publication of reports, developed in consultation with English Heritage, associated with the consented development;

(vi) details of methods for archiving of archaeological material; and

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

(i) a mitigation scheme for any Annex I Habitat identified by the survey referred to in condition 10(2)(a);

(j) an offshore operations and maintenance plan that must be submitted to the MMO at least four months prior to commencement of the operation of the licensed activities and include provision for the review and resubmission of that plan every three years during the operational phase. The offshore operations and maintenance plan must include details of—

(i) information on the presence of Annex I Habitat as identified in condition 10(2)(a);

(ii) information on, including likely schedule of, corrective and preventative maintenance activities proposed during the operation of the licensed activities, as identified in the environmental statement and Schedule of Offshore Maintenance Activities;

(iii) a summary of the environmental impact of the activities listed under sub-paragraph (ii), as identified in the environmental statement and Schedule of Offshore Maintenance Activities, and having regard to sub-paragraph (i); and

(iv) the anticipated maintenance activities that exceed the frequency and/or scope of licensable activities identified in the environmental statement and Schedule of Offshore Maintenance Activities, and the proposed approach to the licensing of these activities.

and each programme, statement, plan, protocol, scheme or other detail required to be approved under this condition must be submitted to the MMO for approval at least four months prior to the commencement of works, except where otherwise stated or unless otherwise agreed by the MMO.

(2) The undertaker must ensure that a copy of any agreed archaeological report is deposited with the National Monuments Record, in accordance with the Online AccesS to the Index of archaeological investigationS (OASIS) system.
