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 Order limits, 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 paragraph (1), 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.

Subject to paragraph 10 of Schedule 10 (protection of Port of Bridgwater) neither the Agency nor the Harbour Authority is 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).
