Section 2.50 - When will the bureau require advance payment?(a) The bureau will require advance payment before starting further work when it finds the estimated fee is over $250 and:(1) You have never made a FOIA request to the Department requiring the payment of fees; or(2) You did not pay a previous FOIA fee within 30 calendar days of the date of billing.(b) If the bureau believes that you did not pay a previous FOIA fee within 30 calendar days of the date of billing, the bureau will require you to either:(1) Demonstrate you paid prior fee within 30 calendar days of the date of billing; or(2) Pay any unpaid amount of the previous fee, plus any applicable interest penalties (see § 2.53 of this subpart), and pay in advance the estimated fee for the new request.(c) When the bureau notifies you that an advance payment is due under paragraph (a) of this section, it will give you an opportunity to reduce the fee by modifying the request.(d) Your payment of the funds you owe the bureau for work it has already completed before records are sent to you is not an advance payment under paragraph (a) of this section.(e) If the bureau requires advance payment, it will start further work only after receiving the advance payment. It will also notify you that it will not be able to comply with your FOIA request unless you provide the advance payment. Unless you pay the advance payment within 20 workdays after the date of the bureau's fee letter, the bureau will presume that you are no longer interested and will close the file on the request. 77 FR 76906 , Dec. 31, 2012, as amended at 81 FR 11130 , Mar. 3, 2016
