31  Seismic or exploratory drilling environment plan to be resubmitted if significantly modified  (1) This section applies if:  (a) the titleholder who submitted a seismic or exploratory drilling environment plan modifies it; and  (b) the plan, as modified, relates to:  (i) a significant modification or new stage of any of the seismic or exploratory drilling activities to which the plan previously related; or  (ii) a seismic or exploratory drilling activity to which the plan did not previously relate; and  (c) the modification is not made in response to comments described in subsection 30(1). Note: Paragraph (c) may apply to a modification under subsection 30(3) if the modification is not made in response to comments.  (2) The titleholder must resubmit the plan (as modified) to NOPSEMA. Note: Under section 27, NOPSEMA must decide provisionally whether the resubmitted plan includes material apparently addressing all the provisions of Division 2 (Contents of an environment plan). If NOPSEMA decides provisionally that the resubmitted plan does include such material, NOPSEMA must publish the resubmitted plan and an invitation for anyone to comment on matters relating to the resubmitted plan: see sections 28 and 30.  (3) NOPSEMA must cease to act under this Division in relation to the plan as it existed before the modification.
