Upon the request of an individual to gain access to the individual’s personal record, an agency shall permit the individual to review the record and have a copy made within ten working days following the date of receipt of the request by the agency unless the personal record requested is exempted under § 92F-22. The ten-day period may be extended for an additional twenty working days if the agency provides to the individual, within the initial ten working days, a written explanation of unusual circumstances causing the delay.
