31.—(1) With respect to any requirement which requires the authorised project to be carried out in accordance with the details approved by the relevant planning authority or another organisation or body, the approved details must be carried out as approved unless an amendment or variation is previously agreed by the relevant planning authority or that other organisation or body in accordance with sub-paragraph (2).
(2) Any amendments to or variations from the approved details must be in accordance with the principles and assessments set out in the environmental statement. Such agreement may only be given in relation to immaterial changes where it has been demonstrated to the satisfaction of the relevant planning authority or that other organisation or body that the subject matter of the agreement sought is unlikely to give rise to any materially greater environmental effects from those assessed in the environmental statement.
(3) The approved details must be taken to include any amendments that may subsequently be approved by the relevant planning authority or that other person.
