Any participant whose comments request new information, studies, or other amendments to the approved study plan must include a demonstration of extraordinary circumstances, pursuant to the requirements of §5.15(f).

(f) A waiver of the requirement to file the Preliminary Licensing Proposal or draft license application may be requested, based on a consensus of the participants in favor of such waiver.
