In compliance with M.G.L. c. 66, § 10, the Department shall, at reasonable times and without unreasonable delay, permit any person, under the supervision of Department personnel, to inspect and examine any public record which is in the custody of the Department and not described in 310 CMR 3.10(1) through (5); and the Department shall furnish one copy of such record on request and on payment of a reasonable fee. Every person for whom a search of public records is made shall pay the actual expense of such search. Unless more time is reasonably required to properly determine whether the records in question are subject to disclosure as public records or exempt from disclosure, the Department shall comply with a written request to inspect or copy a public record within ten days after the Department actually receives the request. Whenever a cost or fee is established or determined by the Commissioner of Administration, said cost or fee shall be paid to the Department.
