5 CFR § 1631.8 - Prompt response.
(a)
(1) When the FOIA Officer receives a request for expedited processing, he or she will determine within 10 work days whether to process the request on an expedited basis.
(2) When the FOIA Officer receives a request for records which he or she, in good faith, believes is not reasonably descriptive, he or she will so advise the requester within 5 work days. The time limit for processing such a request will not begin until receipt of a request that reasonably describes the records being sought.
(b) The FOIA Officer will either approve or deny a reasonably descriptive request for records within 20 workdays after receipt of the request. Whenever the Board cannot meet the statutory time limit for processing a request because of “unusual circumstances,” as defined in the FOIA, and the Board extends the time limit on that basis, the Board must, before expiration of the 20-day period to respond, notify the requester in writing of the unusual circumstances involved and of the date by which the Board estimates processing of the request will be completed. Where the extension exceeds 10 working days, the Board must, as described by the FOIA, provide the requester with an opportunity to modify the request or arrange an alternative time period for processing the original or modified request through the Board's FOIA Public Liaison or FOIA Officer.
(c) When additional time is required for one of the reasons stated in paragraph (b) of this section, the FOIA Officer will extend this time period for an additional 10 work days by written notice to the requester. If the Board will be unable to process the request within this additional time period, the requester will be notified and given the opportunity to—
(1) Limit the scope of the request; or
(2) Arrange with the FOIA Officer an alternative time frame for processing the request.
