The system manager shall make one copy of a record, up to 300 pages, available without charge to a requestor who is an employee of FEMA. The system manager may waive the fee requirement for any other requestor if the cost of collecting the fee is an unduly large part of, or greater than, the fee, or when furnishing the record without charge conforms to generally established business custom or is in the public interest.
