Paragraph 59 Approval of detailed designI1
England and Wales
The undertaker must not commence the construction of any specified work or the exercise of any specified function until plans of the work or function have been approved in writing by the PLA.
The undertaker must submit to the PLA plans of the specified work or specified function together with all relevant core information and must thereafter provide such further particulars as the PLA may, within 20 business days starting with the day on which plans are submitted under this sub-paragraph, reasonably require, and the particulars so supplied are to provide all information necessary to enable the PLA to determine whether approval should be given and, if so, whether conditions should be imposed.
Any approval of the PLA required under this paragraph must not be unreasonably withheld or delayed but may be given subject to such reasonable modifications, terms and conditions as the PLA may make for the protection of—
traffic in, or the flow or regime of, the river Thames;
the use of its land, or the river Thames, for the purposes of performing its functions; or
the performance of any of its functions connected with environmental protection.
Requirements made under sub-paragraph (3) may include conditions as to—
the proposed location of any temporary work and its dimensions or the location where the specified function is proposed to be exercised;
the programming of temporary works or the exercise of the specified function including the timing and management of giving up temporary possession;
the removal of any temporary work and the undertaking by the undertaker of any related work or operation that the PLA considers to be necessary for the purpose of removing or preventing any obstruction to navigation;
the relocation, provision and maintenance of works, moorings, apparatus and equipment necessitated by the specified work or specified function; and
the expiry of the approval if the undertaker does not commence construction or carrying out of the approved specified work or exercise of the specified function within a prescribed period.
Subject to sub-paragraph (6), an application for approval under this paragraph is deemed to have been refused if it is neither given nor refused—
in the case of an application for approval under article 27 (power to dredge), within 40 business days of the paragraph 59 specified day; and
in any other case, within 30 business days of the paragraph 59 specified day.
An approval of the PLA under this paragraph is not deemed to have been unreasonably withheld or delayed if approval within the time limited by sub-paragraph (5) has not been given pending the outcome of any consultation on the approval in question that the PLA is obliged to carry out in the proper exercise of its functions.
The undertaker must carry out all operations for the construction of any specified work or the specified function without unnecessary delay and to the reasonable satisfaction of the PLA so that traffic in, or the flow or regime of, the river Thames, and the exercise of the PLA’s functions, do not suffer more interference than is reasonably practicable. The PLA is entitled at all reasonable times, on giving such notice as may be reasonable in the circumstances, to inspect and survey those operations and the undertaker must provide all reasonable facilities to enable that inspection and survey to take place.
To the extent that the PLA approves under sub-paragraph (1) the carrying out of any specific works or the exercising of any specified functions outside of the limits of deviation of Work No.4, and the physical extent of any existing structures that are authorised by a works licence granted by the PLA under section 66 (licensing of works) of the 1968 Act is changed or any of the existing structures are removed in their entirety as a result of the carrying out of that specified work or exercise of that specific function—
such works shall not constitute a breach of that works licence;
the undertaker must notify the holder of that works licence of the specified works or specified functions that are intended to be carried out on the existing structures, at least 30 business days before the specified works or specified functions are carried out;
within 30 business days following the completion of that specified work or exercise of that specific function, the undertaker must provide the PLA with such information as the PLA may reasonably require as to the changed physical extent or to confirm the entire removal of those existing structures;
unless sub-paragraph (10) applies, the PLA must within 30 business days of receipt of the information referred to in sub-paragraph (c) issue to the holder of the works licence granted by the PLA under section 66 (licensing of works) of the 1968 Act in respect of the existing structures in question a new licence to reflect—
the physical changes to the existing structures; and
any changes to the conditions of the works licence it considers necessary to reflect the physical changes and to meet the requirements of the 1968 Act and the PLA’s duties under it;
from the date of its issue that new licence shall apply to the changed extent of the remaining existing structures in question, the existing works licence shall be revoked, the holder of the licence must comply with the conditions of the new licence and the 1968 Act shall apply to the remaining existing structures and works authorised by the new licence; and
the holder of the works licence for the existing structures in questions shall have the right to appeal the conditions of any new works licence issued by the PLA under sub-paragraph (1)(b) of section 69 (appeal to board of trade) of the 1968 Act.
Where sub-paragraph (8) applies, the undertaker must—
compensate the holder of the works licence for any reasonable increase to the costs of that licence holder of complying with the conditions of the new works licence, compared to the costs of complying with the works licence that previously applied; and
pay the reasonable costs of the PLA in complying with sub-paragraph (8)(d) and in connection with the reasonable costs of the PLA’s participation in any appeal made under sub-paragraph (1)(b) of section 69 (appeal to board of trade) of the 1968 Act in connection with a new works licence issued under sub-paragraph (8)(f).
To the extent that the PLA approves under sub-paragraph (1) the carrying out of any specific works or the exercising of any specified functions outside of the limits of deviation of Work No.4 and all existing structures that are authorised by a works licence granted by the PLA under section 66 (licensing of works) of the 1968 Act are removed in their entirety as a result of the carrying out of that specified work or exercise of that specific function, and article 8 does not apply—
following the completion of that specified work or exercise of that specific function, the undertaker must provide the PLA with information to demonstrate that the existing structures have been removed in their entirety; and
upon the PLA being satisfied that the existing structures have been removed in their entirety it must—
notify the undertaker that it is so satisfied; and
write to the holder of the works licence to confirm that that works licence is terminated.
Where sub-paragraph (10) applies, the undertaker must pay the reasonable costs of the PLA in complying with sub-paragraph (10)(b).
In this paragraph—
“commence” includes the permitted preliminary works where they take place in the river Thames,
“plans” shall, in respect of the exercising of article 27, only mean such information which the PLA publishes on its website from time to time as being required to accompany an application for a licence to dredge under section 73 (licensing of dredging, etc.) of the 1968 Act and any documents required by the PLA pertaining to sampling, but not any other document listed under the definition of plans in paragraph 58, in respect of the exercising of article 27, and
