(a) When an agency has a significant number of requests, the nature of which precludes a determination within 20 working days, the requests may be processed in a multitrack processing system, based on the date of receipt, the amount of work and time involved in processing the request, and whether the request qualifies for expedited processing.
(b) Agencies may establish as many processing tracks as appropriate; processing within each track shall be based on a first-in, first-out concept, and rank-ordered by the date of receipt of the request.
(c) Agencies may provide a requester whose request does not qualify for the fastest track an opportunity to limit the scope of the request in order to qualify for a faster track. This multitrack processing system does not lessen agency responsibility to exercisedue diligence in processing requests in the most expeditious manner possible.
(d) Agencies shall process requests in each track on a “first-in, first-out” basis, unless there are unusual circumstances as set forth in§ 1.16, or the requester is entitled to expedited processing as set forth in § 1.9.
