Approved plans and amendments to approved plans
31.—(1) Where a Requirement requires the authorised development to be carried out in accordance with a plan, scheme, statement, strategy, details or protocol (the “plan”) approved by the relevant planning authority or Natural Resources Wales, the approved plan must be taken to include any amendments that may be approved subsequently by the relevant planning authority or Natural Resources Wales (after consulting every person required to be consulted before approval of the original plan).
(2) The relevant planning authority or Natural Resources Wales must not approve the plan or an amendment to the plan unless it is satisfied that the plan or the amendment is unlikely to give rise to any new or materially different environmental effects from those assessed in the environmental statement.
