Within the time prescribed by applicable law following the receipt of a request, the agency shall determine whether to grant or to deny the request and shall dispatch its determination to the requester, unless an extension is made pursuant to §§ 405.2 and 405.3 of this section.
In unusual circumstances as specified in § 405.3, the agency may extend the time for initial determination on a request up to the time prescribed by applicable law.
An extension shall be made by written notice to the requester, which shall set forth the reason or reasons for the extension. As used in this section "unusual circumstances" means, but only to the extent necessary to the proper processing of the request, either of the following:
If no determination has been dispatched at the end of the period prescribed by law or the extension thereof, the requester may deem his or her request denied, and exercise a right of appeal in accordance with § 412.
When no determination can be dispatched within the applicable time limit, the agency shall nevertheless continue to process the request. On expiration of the time limit, the agency shall inform the requester of the following:
The agency may ask the requester to forego appeal until a determination is made.
For purposes of this chapter, a request is deemed received when the designated Freedom of Information Officer, or agency head in the absence of a designated Freedom of Information Officer, receives the request submitted in compliance with the Act and this chapter. When the Freedom of Information Officer, pursuant to § 402.5, contacts the requester for additional information, then the request is deemed received when the Freedom of Information Officer receives the additional information.
