(a) When GSA determines or estimates that the fees to be assessed in accordance with this section shall exceed $49.00, the agency shall notify the requester of the actual or estimated amount of the fees, including a breakdown of the fees for search, review or duplication, unless the requester has indicated a willingness to pay fees as high as those anticipated via writing. If only a portion of the fee can be estimated readily, GSA shall advise the requester accordingly. If the request is not for noncommercial use, the notice shall specify that the requester is entitled to the statutory entitlements of 100 pages of duplication at no charge and, if the requester is charged search fees, 2 hours of search time at no charge, and shall advise the requester whether those entitlements have been provided.

(b) If GSA notifies the requester that the actual or estimated fees are in excess of $49.00, the request shall not be considered received and further work shall not be completed until the requester commits in writing to pay the actual or estimated total fee, or designates some amount of fees the requester is willing to pay. Or in the case of a noncommercial use requester who has not yet been provided with the requester's statutory entitlements, designates that the requester seeks only that which can be provided by the statutory entitlements. The requester shall provide the commitment/or designate an exact dollar amount in writing the requester is willing to pay. GSA is not required to accept payments in installments.

(c) If the requester has indicated a willingness to pay some designated amount of fees, but the agency estimates that the total fee shall exceed that amount, GSA shall toll the processing of the request when it notifies the requester of the estimated fees in excess of the amount the requester has indicated a willingness to pay. GSA shall inquire whether the requester wishes to revise the amount of fees the requester is willing to pay or modify the request. Once the requester submits the new estimated fee, the time to respond shall resume from where it was at the date of the notification.

(d) GSA's FOIA Public Liaison and other FOIA professionals shall be available to assist any requester in reformulating a request to meet the requester's needs at a lower cost.

(e) Although not required to provide special services, if GSA chooses to do so as a matter of administrative discretion, the direct costs of providing the service shall be charged. Examples of such services include certifying that records are true copies, providing multiple copies of the same document, or sending records by means other than first class mail.

(f) GSA may charge interest on any unpaid bill starting on the 31st day following the date the requester is first billed. Interest charges shall be assessed at the rate provided in 31 U.S.C. 3717 and shall accrue from the billing date until payment is received by the agency. GSA shall follow the provisions of the Debt Collection Act of 1982 (Public Law 97-365, 96 Stat. 1749), as amended, and its administrative procedures, including the use of consumer reporting agencies, collection agencies, and offset.

(g) When GSA reasonably believes that a requester or a group of requesters acting in concert are attempting to divide a single request into a series of requests for the purpose of avoiding fees, GSA may aggregate those requests and charge accordingly. GSA may presume that multiple requests of this type made within a 30-day period have been made in order to avoid fees. For requests separated by a longer period, GSA shall aggregate them only where there is a reasonable basis for determining that aggregation is warranted in view of all the circumstances involved. Multiple requests involving unrelated matters cannot be aggregated.
