Obstruction in the river

68.—(1) If any pile, stump or other obstruction to navigation becomes exposed as a result of constructing any tidal work, or if any construction equipment or material is misplaced in or adjacent to the river and causes obstruction to navigation, the undertaker must, as soon as reasonably practicable after the receipt of notice in writing from the Port Authority requiring such action, remove it from the river or, in the case of any pile, stump or other obstruction to navigation, if it is not reasonably practicable to remove it—

(a) cut the obstruction off at such level below the bed of the river as the Port Authority may reasonably direct; or

(b) take such other steps to make the obstruction safe as the Port Authority may reasonably require.

(2) If, after such reasonable period as may be specified in a notice under this paragraph, the undertaker has failed to begin taking steps to comply with the requirements of the notice, or after beginning has failed to make reasonably expeditious progress towards their implementation, the Port Authority may carry out the works specified in the notice and any expenditure reasonably incurred by it in so doing is recoverable from the undertaker.
