36 CFR 1253.8 - Notification process for changes in hours.
(b) Changing hours of operations for research rooms, exhibit areas and museums may not be arbitrary. Proposed changes must be documented by evidence of a business need to change the hours of operation.
(c) The notification process must proceed as follows:
(1) Post a notice on http://www.archives.gov.
(2) Post notices in areas visible to the public in their research room, exhibit areas or museum.
(3) Issue a press release, e-mail notification, or other means normally used by that unit to notify the public of events at their location.
(4) These notices will provide written determination justifying the change in hours.
(d) In the event that emergency changes to hours of operations for research rooms, exhibit areas and museums are necessary, including but not limited to inclement weather, NARA units will give as much advance notice to the public as possible. Emergency notification will be posted at http://www.archives.gov.
