(a) CIGIE processes requests using a multitrack processing system. There are four processing tracks: An expedited track, if the request qualifies; a simple track for relatively simple requests; a complex track for more complex and lengthy requests; and a remanded track, when a FOIA appeal is granted.
(b) CIGIE processes requests on a ``first-in, first-out'' basis for each track, unless there are unusual circumstances as referenced in Sec. 9800.14, or the requester is entitled to expedited processing as described in Sec. 9800.11.
