The Llangollen and Corwen Railway Order 2010

4.—(1) Subject to sub-paragraph (2), any specified work, and all protective works required by the Environment Agency under paragraph 3, shall be constructed—

(i) with all reasonable despatch in accordance with the plans approved or deemed to have been approved or settled under this Schedule; and

(ii) to the reasonable satisfaction of the Environment Agency,

and the Environment Agency shall be entitled by its officer to watch and inspect the construction of such works.

(2) The undertaker shall give to the Environment Agency not less than 14 days' notice in writing of its intention to commence construction of any specified work and notice in writing of its completion not later than 7 days after the date on which it is brought into use.

(3) If any part of the authorised works comprising a structure in, over or under a drainage work is constructed otherwise than in accordance with the requirements of this Schedule, the Environment Agency may by notice in writing require the undertaker, at the undertaker’s own expense, to comply with the requirements of this Schedule or (if the undertaker so elects and the Environment Agency in writing consents, such consent not to be unreasonably withheld) to remove, alter or pull down the authorised work and, where removal is required, to restore the site to its former condition to such extent and within such limits as the Environment Agency reasonably requires.

(4) Subject to sub-paragraph (5) and paragraph 8, if within a reasonable period, being not less than 28 days from the date when a notice under sub-paragraph (3) is served upon the undertaker, it has failed to begin taking steps to comply with the requirements of the notice and subsequently to make reasonably expeditious progress towards their implementation, the Environment Agency may execute the works specified in the notice and any expenditure incurred by it in so doing shall be recoverable from the undertaker.

(5) In the event of any dispute as to whether sub-paragraph (3) is properly applicable to any work in respect of which a notice has been served under that sub-paragraph, or as to the reasonableness of any requirement of such a notice, the Environment Agency shall not except in emergency exercise the powers conferred by sub-paragraph (4) until the dispute has been finally determined.
