Paragraph 8 I1

If during the construction of the specified works it is agreed, or in the absence of agreement it is proved to the satisfaction of an arbitrator appointed under article 41 (arbitration), that any accumulation or erosion has been caused wholly or partly by the construction of the specified works or exercise of powers under this Order, the relevant undertaker, if so requested by A. B. Ports acting reasonably, must remedy the accumulation or erosion to the extent attributable to the construction or exercise of powers.

If the relevant undertaker refuses or fails to do so, A. B. Ports may itself cause the work to be done and may recover the reasonable cost of doing so from the relevant undertaker.
