2.—(1) Before—
(a)submitting any plans and sections for any tidal work to the Secretary of State for her approval under article 16 (tidal works not to be constructed without approval of the Secretary of State);
(b)commencing any operation for the construction of a tidal work where approval of the Secretary of State under article 16 (tidal works not to be constructed without approval of the Secretary of State) is not required; or
(c)commencing any operation for the maintenance of a tidal work,
the Harbour Authority shall submit to the PLA plans and sections of the tidal work or operation and such further particulars as the PLA may, within 28 days from the day on which the plans and sections are submitted under this sub-paragraph, reasonably require.
(2) No application for the Secretary of State’s approval under article 16 (tidal works not to be constructed without approval of the Secretary of State) shall be made in respect of a tidal work until plans and sections in respect of that tidal work submitted under sub-paragraph (1) have been approved by the PLA.
(3) Any tidal work not requiring the Secretary of State’s approval under article 16 (tidal works not to be constructed without approval of the Secretary of State) shall not be constructed, and no tidal work shall be maintained, except in accordance with such plans as may be approved in writing by the PLA or determined under paragraph 24.
(4) Any approval of the PLA required under this paragraph shall not be unreasonably withheld but may be given subject to such reasonable requirements as the PLA may make for the protection of—
(a)traffic in, or the flow or regime of, the river;
(b)the use of its operational land or the river for the purposes of performing its functions; or
(c)the performance of any of its functions connected with environmental protection.
(5) Requirements made under sub-paragraph (4) may include conditions as to—
(a)the relocation, provision and maintenance of works, moorings, apparatus and equipment necessitated by the tidal work; and
(b)the expiry of the approval if the Harbour Authority does not commence construction of the tidal work approved within a prescribed period.
(6) Subject to sub-paragraphs (8) and (9), any such approval shall be deemed to have been refused if it is neither given nor refused within 42 days of the specified day.
(7) Before making a decision on any such approval, the PLA shall take into account any opinion on the plans and sections provided to it by the Environment Agency.
(8) Accordingly, an approval of the PLA under this paragraph shall not be deemed to have been unreasonably withheld if approval within the time limited by sub-paragraph (6) has not been given pending the outcome of any consultation on the approval in question that the PLA is obliged in the proper exercise of its functions to carry out provided that during the course of such consultation, the PLA has acted with all due expedition.
(9) In this paragraph “the specified day” means, in relation to any tidal work—
(a)the day on which plans of that work are submitted to the PLA under sub-paragraph (1); or
(b)the day on which the Harbour Authority provides the PLA with all such particulars of the work as have been requested by the PLA under that sub-paragraph;
whichever is the later.
(10) Whenever the Harbour Authority provides the Secretary of State with an environmental document it shall at the same time send a copy to the PLA.
3. Subject to paragraph 21, no tidal work shall be subject to any of the controls in sections 66 to 75 of the 1968 Act.
4. Any operations for the construction of any tidal work approved in accordance with this Order shall, once commenced, be carried out by the Harbour Authority with all reasonable dispatch and to the reasonable satisfaction of the PLA so that river traffic, the flow or regime of the river and the exercise of the PLA’s functions shall not suffer more interference than is reasonably practicable, and the PLA shall be entitled by its officer at all reasonable times, on giving such notice as may be reasonable in the circumstances, to inspect and survey such operations.
