Paragraph 42 Amendments to approved detailsI1

With respect to any Requirement which requires the authorised development to be carried out in accordance with the details approved by the relevant planning authority or another approval authority as specified in the Requirement (the “discharging authority”), the approved details must be carried out as approved unless an amendment or variation is agreed in advance by the discharging authority, in accordance with sub-paragraph (2), and in consultation with any body specified in the relevant Requirement.

Where any Requirement specifies “unless otherwise agreed” by the discharging authority such agreement shall not be given except in relation to immaterial changes where it has been demonstrated to the satisfaction of the discharging authority that the agreement sought is unlikely to give rise to any materially new or materially different environmental effects from those assessed in the environmental statement.

The approved details shall include any amendments that may subsequently be agreed by the discharging authority.
