The River Thames (Hungerford Footbridges) Order 1999

18.—(1) The undertaker shall not commence tidal works until it has supplied to the Port Authority such proper and sufficient plans for the same as the Port Authority shall reasonably require and those plans have been approved in writing by the Port Authority (such approval not to be unreasonably withheld).

(2) A tidal work shall not be placed or constructed on the bed of the river under the provision of this Order unless the tidal work—

(a) has been previously approved by the Secretary of State; or

(b) if such approval has not been previously obtained a condition has been imposed in any approval given by the Port Authority to plans under the provisions of sub-paragraph (1) above that that tidal work will be removed if the Secretary of State so requires.

(3) The Port Authority shall notify the undertaker within a period of 28 days starting with the date on which such plans of tidal works have been furnished to the Port Authority, or such longer period as may be agreed in writing by the Port Authority and the undertaker, of its approval or disapproval of those plans.

(4) Any approval of the Port Authority required under this paragraph may be given subject to such reasonable conditions as the Port Authority may make for the protection of—

(a) vessel movement on, or the flow or regime of, the river, or

(b) the use of its land or the river for the purposes of performing its statutory functions,

including any relocation, or provision, of works, new works, moorings, apparatus and equipment necessitated by the tidal works, or any other works authorised by the Order, or their construction or maintenance.

(5) If within a period of 28 days starting from the date on which it receives proper and sufficient plans of a tidal work under sub-paragraph (1) above the Port Authority does not notify the undertaker of its approval or disapproval of those plans, it shall be deemed to have disapproved of the said plans or such part of the plans as it has not approved.

(6) Where the undertaker is aggrieved by—

(a) the disapproval of the Port Authority of any plans submitted under sub-paragraph (1) above,

(b) any term or condition upon which the Port Authority propose to approve the plans, or

(c) any modification by the Port Authority of the plans,

it may within 28 days from the date upon which the Port Authority is deemed to have notified its disapproval of the plans or the date upon which the Port Authority notifies the undertaker of its decision, as the case may be, appeal to the Secretary of State.

(7) If an appeal to the Secretary of State is made, the following provisions shall apply—

(a) the appeal shall be made by written notice stating the grounds of the appeal,

(b) the appellant shall send a copy of the notice of appeal to the Port Authority,

(c) the Port Authority may make written representations to the Secretary of State within 14 days from receipt by it of the copy notice of appeal, and if it does so shall forthwith send a copy of its representations to the appellant,

(d) the Secretary of State may confirm, vary or revoke a decision or requirement against which an appeal is made and may make any consequential amendments necessary, and

(e) the Secretary of State may direct the Port Authority or the undertaker to give effect to the decision of the Secretary of State on the appeal and the Port Authority or the undertaker (as the case may be) shall forthwith comply with any direction given.

(8) Without prejudice to the requirements which may be imposed by the Port Authority on the approval of plans for tidal works—

(a) no more than two spans of Charing Cross Railway Bridge and the approaches to those spans shall be blocked partially or wholly to navigation at any one time,

(b) the two main navigation spans of Charing Cross Railway Bridge, being the second and third spans over the river from the Westminster shore, and the approaches to those spans, must not be blocked wholly, or partially, to navigation at the same time, and

(c) save for the span nearest to the Lambeth shore, the tidal works must not affect the width and headroom of the present spans of Charing Cross Railway Bridge as extended by the tidal works nor the depth of water beneath the spans without the prior agreement of the Port Authority.

(9) The undertaker shall carry out all operations for the construction or maintenance of any tidal works with all reasonable despatch and to the reasonable satisfaction of the Port Authority so that vessel movement on, or the flow, or regime of the river and the exercise of the Port Authority’s statutory functions shall not suffer more interference than is reasonably practicable and the Port Authority shall be entitled at all reasonable times, on giving such notice as may be reasonable in the circumstances, to inspect and survey such operations.

(10) If any tidal work is constructed otherwise than in accordance with the requirements of this part of this Schedule or with any condition in an approval pursuant to sub-paragraph (4) above, the Port Authority may by notice in writing require the undertaker at the undertaker’s own expense to comply with the requirements of this part of this Schedule or that condition and if the undertaker does not do so or is unable to do so then the Port Authority may in writing require the undertaker to remove, alter or pull down the tidal work and where the tidal work is removed to restore the site of that work to its condition prior to the construction of the tidal work to such an extent and within such limits as the Port Authority think proper.

(11) The undertaker shall, upon completion of the construction or maintenance of any part of an authorised work, remove as soon as is practicable any temporary tidal works and materials for such temporary tidal works carried out or placed only for the purposes of that part of the authorised work and any materials which formed part of the existing Hungerford footbridge which have been dismantled and have not been removed, and shall make good the site to the reasonable satisfaction of the Port Authority.

(12) The undertaker shall not—

(a) deposit in or allow to fall or be washed into the river any gravel, soil or other material except to the extent permitted by any approval of a tidal work;

(b) discharge or allow to escape either directly or indirectly into the river any offensive or injurious matter in suspension or otherwise; or

(c) discharge into the river any water by any watercourse, public sewer or drain without the consent of the Port Authority and such consent may be given subject to such terms and conditions as the Port Authority may reasonably impose but shall not be unreasonably withheld.

(13) The undertaker shall (subject to sub-paragraph (14) below) remove from the river any pile, stump or other obstruction which becomes exposed in consequence of a tidal work.

(14) If it is not reasonably practicable to remove a pile, stump or other obstruction it shall be cut off at such level below the bed of the river as the Port Authority may direct.

(15) If the undertaker fails to remove or cut off (as the case may be) any pile, stump or other obstruction pursuant to sub-paragraphs (13) and (14) above within a period of 28 days beginning with the date of receipt of a written notice from the Port Authority requiring its removal or cutting off, the Port Authority may carry out the removal or cutting off and recover the cost of doing so from the undertaker.

(16) If a tidal work is abandoned or falls into decay, the Port Authority may by notice in writing require the undertaker either to repair or restore the tidal work, or any part of it, or to remove the tidal work and restore the site of that work to its condition prior to the construction of the tidal work, to such an extent and to such limits as the Port Authority think proper.

(17) If a work consisting partly of a tidal work and partly of works on or over land above the level of high water spring tides is abandoned or falls into decay and that part of the works on or over land above the level of high water springs is in such condition as to interfere or cause reasonable apprehension that it may interfere with the right of navigation on the river or other public rights over the foreshore, the Port Authority may include that part of the works or any portion thereof in any notice under sub-paragraph (16).

(18) If on the expiration of such reasonable period as may be specified in a notice under sub-paragraph (16) above the work specified therein has not been completed to the satisfaction of the Port Authority, the Port Authority may undertake that work and any expenditure reasonably incurred by them in so doing shall be recoverable from the undertaker.

(19) On completion of the construction of the tidal works, the undertaker shall supply to the Port Authority a plan on a scale of not less than 1 in 2500 and sections and elevations on the scale of not less than 1 in 100 showing to the Port Authority’s reasonable satisfaction the situation and levels of the permanent tidal works at that time.
