Regulation 54 Further Information and evidence relating to environmental statements
The development corporation, when considering a specific development application in relation to which an environmental statement has been provided, may in writing require the applicant to provide such further information as they may specify to enable the application to be determined, or to enable them to take fully into consideration any matter which under these Regulations is required to be dealt with in the environmental statement; and where in the opinion of the development corporation—
the applicant could (having regard in particular to current knowledge and methods of assessment) provide further information about any matter mentioned in paragraph 3 of Schedule 3; and
that further information is reasonably required to give proper consideration to the likely environmental effects of the proposed development,
they shall notify the applicant in writing, and he shall provide that further information.
The development corporation may in writing require the applicant to produce to them such evidence, in respect of any environmental statement which it falls to them to take into consideration, as they may reasonably call for to verify any information it contains.
