45 CFR 612.5 - Timing of responses to requests.
(a) In general. The NSF and its component, OIG, ordinarily will initiate processing of requests according to their order of receipt.
(b) Multitrack processing.
(1) NSF and OIG may use two or more processing tracks by distinguishing between simple and more complex requests based on the amount of work and/or time needed to process the request, including through limits based on the number of pages involved. If NSF or OIG does so, it shall advise requesters in its slower track(s) of the limits of its faster track(s).
(2) NSF or OIG using multitrack processing may provide requesters in its slower track(s) with an opportunity to limit the scope of their requests in order to qualify for faster processing within the specified limits of the NSF's or OIG's faster track(s). The requester may be contacted by telephone, email, or letter, whichever is more efficient in each case.
(c) Time for response. The NSF will seek to take appropriate action within 20 days of when a request is properly received or is perfected (excluding the date of receipt, weekends, and legal holidays), whichever is later. A request which otherwise meets the requirements of § 612.3 is perfected when you have reasonably described the records sought under § 612.3(d), and agreed to pay fees under § 612.3(e), or otherwise met the fee requirements under § 612.10.
(d) Unusual circumstances.
(1) Where the time limits for processing a request cannot be met because of unusual circumstances, as defined in the FOIA, the NSF FOIA Officer or the OIG component will notify the requester as soon as practicable in writing of the unusual circumstances and may extend the response period for up to ten working days.
(2) Where the extension is for more than ten working days, the FOIA Officer or the OIG component will provide the requester with an opportunity either to modify the request so that it may be processed within the ten day extension period or to arrange an agreed upon alternative time period with the FOIA Officer or the OIG component for processing the request or a modified request.
(3) Where the NSF reasonably believes that multiple requests submitted by a requester, or by a group of requesters acting in concert, constitute a single request that would otherwise involve unusual circumstances, and the requests involve clearly related matters, they may be aggregated. Multiple requests involving unrelated matters will not be aggregated.
(e) Expedited processing.
(1) If you want to receive expedited processing, you must submit a statement, certified to be true and correct to the best of your knowledge and belief, explaining in detail the basis for requesting expedited processing.
(i) Requests and appeals will be given expedited treatment whenever it is determined that a requester has demonstrated compelling need by presenting:
(A) Circumstances in which the lack of expedited treatment could reasonably be expected to pose an imminent threat to the life or physical safety of an individual; or
(B) An urgency to inform the public about an actual or alleged Federal government activity, if made by a person primarily engaged in disseminating information.
(ii) For example, a requester who is not a full-time member of the news media must establish that he or she is a person whose main professional activity or occupation is information dissemination, though it need not be his or her sole occupation. Such requester also must establish a particular urgency to inform the public about the government activity involved in the request, beyond the public's right to know about government activity generally, and that the information sought has particular value that would be lost if not disseminated quickly.
(3) Within ten calendar days of receipt of a request for expedited processing, the NSF FOIA Officer or OIG component will decide whether to grant it, and will notify the requester of the decision orally or in writing. If a request for expedited treatment is granted, the request will be processed as soon as practicable. If a request for expedited processing is denied, any appeal of that decision will be acted on expeditiously.
