If the disposal of the arisings has not been assessed within the environmental statement a separate marine licence will also be required.

(a) loading facilities;

(b) vessels;

(c) equipment;

(d) shipment routes;

(e) working schedules; and

(f) all components and materials to be used in the construction of the authorised development.

(8) No licensed activities shall commence until the MMO has approved the audit sheet in writing.

(9) The audit sheet shall be maintained throughout the construction of the authorised development and any changes notified immediately in writing to the MMO.

(10) In the event that—

(a) any of the materials on the audit sheet cannot be accounted for the MMO will require the undertaker to carry out a side scan sonar survey to plot all obstructions across the Order limits;

(b) any materials that cannot be accounted for are not located within the Order limits the MMO will require the undertaker to extend the side scan sonar survey to cover routes outside the Order limits used by the vessels in undertaking the authorised development.

(11) Local fishermen shall be invited to send a representative to be present during the side scan sonar survey. Any new obstructions that the MMO believes to be associated with the authorised development shall be removed at the undertaker’s expense.

(12) For the purposes of this licence condition—

(a) “best environmental practice” means best environmental practice as defined in Appendix 1 of the 1992 OSPAR Convention on the Protection of the Marine Environment of the North-East Atlantic;

(b) “EHS law” means all applicable legislation, regulations and legally binding codes of practice and guidance notes issued by regulatory authorities in so far as they relate to or apply to matters relating to the occupational health and safety of any person and/or to the pollution or protection of air, water, land or any or all organisms (including man).
