(b)the failure of any such work,
damage to a fishery is caused, or the Agency has reason to expect that such damage may be caused, the Agency may serve notice on the nominated undertaker requiring it to take such steps as may be reasonably practicable to make good the damage or, as the case may be, to protect the fishery against such damage.
