Extension of review periods: Board requires timely, complete proposals and stated deadlines to permit committee constitution or extension. The Board directs that complete proposals for constitution or reconstitution of Review Committees and any requests for extension of the review period must be submitted at least 21 days before the review deadline, that the last date for review be prominently indicated, and that suggestions for the committee composition be provided, to ensure timely issuance of Board orders and procedural compliance.
