13.—(1) Subject to paragraph (2), a harbour authority shall make charges (“waste charges”) in respect of ships to which this regulation applies.
(2) Where a waste management plan approved by the Secretary of State pursuant to regulation 8(1) or prepared by him pursuant to regulation 9 specifies that in relation to a specified terminal the charges under this regulation are to be made by the terminal operator rather than the harbour authority, the terminal operator shall make charges for ships to which this regulation applies.
(3) A harbour authority or terminal operator (as the case may be) shall arrange for the amount of the charges made by it, and the basis on which they have been calculated, to be published in such manner as will bring them to the notice of persons likely to be affected.
(4) Any ship using a harbour or terminal shall pay the charges made under paragraph (1) or (2) to the harbour authority or terminal operator, as the case may be.
