Part II Protection Against Siltation or Scouring

1 (1) The following provisions of this Part of this Schedule shall, unless otherwise agreed in writing in respect of any matter between the Secretary of State and any of the following bodies concerned in that matter, have effect for the protection of the interests of the Central Electricity Generating Board, RTZ Estates Limited, Civil and Marine Limited, B.V. Schieveem trading as Thames Matex and Dartford International Ferry Terminal Limited in the installations specified in paragraph 2 below.

(2) In this Part of this Schedule—

• “dolphin” means a pylon or post extending above high water level provided for mooring or berthing;

• “protected body” means any of the bodies mentioned in sub-paragraph (1) above;

• “scouring” includes disturbance or collapse of the foreshore or bed of the river; and

• “tidal work” means so much as is on land below the level of mean high-water springs of any of the works authorised by this Act.

2 If—

(a) within the period beginning with the commencement of the construction of the bridge and ending ten years from the completion of that construction, any part of the river becomes subjected to silting or scouring which is wholly or partly caused by a tidal work; or

(b) within the period of ten years beginning with the commencement of the carrying out of any tidal work in connection with the maintenance or improvement of the bridge, any part of the river becomes subjected to silting or scouring which is wholly or partly caused by that tidal work;

and that silting or scouring prejudices the stability or operation of, or, as the case may be, the access of vessels to or from, and the berthing of vessels at, any exisiting installation of a protected body specified in the following table, the Secretary of State, if so requested by notice given by that body within that period, shall carry out such works or operations in the river as may be necessary to make good the silting or scouring in so far as, in either case, that silting or scouring is attributable to a tidal work.
