(1) Except under extraordinary circumstances, a response shall be given to a request for records no more than five business days after receipt of the request.

(2) If, because of extraordinary circumstances, more than five business days are required to respond to a request, receipt of the request shall be acknowledged within five business days after the request is received. The acknowledgment shall state the reason for delay and estimate the date when a reply will be made. If access to records is neither granted nor denied within 10 business days after the date of acknowledgment of receipt of a request, the failure to respond may be construed as a denial of access that may be appealed.
