4901.16—Extensions of time.
In unusual circumstances (as described in subparagraph (a)(6)(B) of FOIA), the time to respond to a disclosure request under § 4901.14(a) or an appeal under § 4901.15(b) may be extended as reasonably necessary to process the request or appeal. The disclosure officer (with the prior approval of the General Counsel) or the General Counsel, as appropriate, shall notify the requester in writing within the original time period of the reasons for the extension and the date when a response is expected to be sent. The maximum extension for responding to a disclosure request shall be 10 working days, and the maximum extension for responding to an appeal shall be 10 working days minus the amount of any extension on the request to which the appeal relates.
