In case of damage to, or destruction or decay of, a tidal work or any part of it, the undertaker must as soon as reasonably practicable notify the Tees Port Authority and must lay down such buoys, exhibit such lights and take such other steps for preventing danger to navigation as the Tees Port Authority may from time to time direct.

Subject to article 33 (defence to proceedings) if the undertaker fails to comply in any respect with a direction given under paragraph (1) it is guilty of an offence and liable on summary conviction to a fine not exceeding level 3 on the standard scale.
