  "text": "(1) The undertaker may at any time maintain the authorised development, except to the extent that this Order or an agreement made under this Order provides otherwise. No maintenance works whose likely effects on the environment are not assessed in the environmental statement shall take effect, unless otherwise approved by the MMO or the relevant planning authority. The Schedule of Offshore Maintenance Activities identifies those offshore maintenance activities that have been assessed in the environmental statement.\n(2) Where the MMO or relevant planning authority’s approval is required under paragraph (1), such consent must only be given in relation to immaterial changes where it has been demonstrated to the satisfaction of the discharging authority that the approval ... sought is unlikely to give rise to any materially new or materially different environmental effects from those assessed in the environmental statement.",
