Regardless of anything in any other enactment or in any rule of law, the Agency may temporarily close the river or any part of it within the limits of deviation, to navigation during or for the purposes of executing any works or doing anything authorised by or under this Order.

In exercising the powers conferred by this article, the Agency must seek to minimise interference with navigation on the river so far as is reasonably practicable and consistent with the efficient and economical execution of the works.

The Agency must not exercise the powers conferred by paragraph (1) so as to preclude access from the river to the Wet Dock without the consent of A.B. Ports (such consent not to be unreasonably withheld).

Subject to paragraph 10 of Schedule 7 (protection of A.B. Ports) neither the Agency nor A.B. Ports is to be liable for any costs, damages or expenses whatsoever incurred by any person as a result, directly or indirectly, of any closure of the river under paragraph (1).
