Mass. Gen. Laws ch. 66, § 10
(iii) the records access officer receives payment of a reasonable fee as set forth in subsection (d).
A request for public records may be delivered to the records access officer by hand or via first class mail at the record officer's business address, or via electronic mail to the address posted by the agency or municipality that the records access officer serves.
(c) If the magnitude or difficulty of a request, or the receipt of multiple requests from the same requestor, unduly burdens the other responsibilities of the agency or municipality such that an agency or municipality is unable to complete the request within the time provided in clause (vi) of subsection (b), a records access officer may, as soon as practical and within 20 business days after initial receipt of the request, or within 10 business days after receipt of a determination by the supervisor of public records that the requested record constitutes a public record, petition the supervisor of records for an extension of the time for the agency or municipality to furnish copies of the requested record, or any portion of the requested record, that the agency or municipality has within its possession, custody or control and intends to furnish. The records access officer shall, upon submitting the petition to the supervisor of records, furnish a copy of the petition to the requestor. Upon a showing of good cause, the supervisor of records may grant a single extension to an agency not to exceed 20 business days and a single extension to a municipality not to exceed 30 business days. In determining whether the agency or municipality has established good cause, the supervisor of records shall consider, but shall not be limited to considering:
(vi) the public interest served by expeditious disclosure.
If the supervisor of records determines that the request is part of a series of contemporaneous requests that are frivolous or designed to intimidate or harass, and the requests are not intended for the broad dissemination of information to the public about actual or alleged government activity, the supervisor of records may grant a longer extension or relieve the agency or municipality of its obligation to provide copies of the records sought. The supervisor of records shall issue a written decision regarding a petition submitted by a records access officer under this subsection within 5 business days following receipt of the petition. The supervisor of records shall provide the decision to the agency or municipality and the requestor and shall inform the requestor of the right to seek judicial review of an unfavorable decision by commencing a civil action in the superior court.
(d) A records access officer may assess a reasonable fee for the production of a public record except those records that are freely available for public inspection. The reasonable fee shall not exceed the actual cost of reproducing the record. Unless expressly provided for otherwise, the fee shall be determined in accordance with the following:
(iv) the supervisor of records may approve a petition from an agency or municipality to charge for time spent segregating or redacting, or a petition from a municipality to charge in excess of $25 per hour, if the supervisor of records determines that (A) the request is for a commercial purpose; or (B) the fee represents an actual and good faith representation by the agency or municipality to comply with the request, the fee is necessary such that the request could not have been prudently completed without the redaction, segregation or fee in excess of $25 per hour and the amount of the fee is reasonable and the fee is not designed to limit, deter or prevent access to requested public records; provided, however, that:
1. in making a determination regarding any such petition, the supervisor of records shall consider the public interest served by limiting the cost of public access to the records, the financial ability of the requestor to pay the additional or increased fees and any other relevant extenuating circumstances;
2. an agency or municipality, upon submitting a petition under this clause, shall furnish a copy of the petition to the requestor;
3. the supervisor of records shall issue a written determination with findings regarding any such petition within 5 business days following receipt of the petition by the supervisor of public records; and
4. the supervisor of records shall provide the determination to the agency or municipality and the requestor and shall inform the requestor of the right to seek judicial review of an unfavorable decision by commencing a civil action in the superior court;
