(a) If a request for a copy of public information will result in the imposition of a charge under this subchapter that exceeds $40, or a request to inspect a paper record will result in the imposition of a charge under § 552.271 that exceeds $40, the governmental body shall provide the requestor with a written itemized statement that details all estimated charges that will be imposed, including any allowable charges for labor or personnel costs. If an alternative less costly method of viewing the records is available, the statement must include a notice that the requestor may contact the governmental body regarding the alternative method. The governmental body must inform the requestor of the responsibilities imposed on the requestor by this section and of the rights granted by this entire section and give the requestor the information needed to respond, including:
(1) that the requestor must provide the governmental body with a mailing, facsimile transmission, or electronic mail address to receive the itemized statement and that it is the requestor’s choice which type of address to provide;
(2) that the request is considered automatically withdrawn if the requestor does not respond in writing to the itemized statement and any updated itemized statement in the time and manner required by this section; and
(3) that the requestor may respond to the statement by delivering the written response to the governmental body by mail, in person, by facsimile transmission if the governmental body is capable of receiving documents transmitted in that manner, or by electronic mail if the governmental body has an electronic mail address.
(b) A request described by Subsection (a) is considered to have been withdrawn by the requestor if the requestor does not respond in writing to the itemized statement by informing the governmental body within 10 business days after the date the statement is sent to the requestor that:
(1) the requestor will accept the estimated charges;
(2) the requestor is modifying the request in response to the itemized statement; or
(3) the requestor has sent to the attorney general a complaint alleging that the requestor has been overcharged for being provided with a copy of the public information.

(c) If the governmental body later determines, but before it makes the copy or the paper record available, that the estimated charges will exceed the charges detailed in the written itemized statement by 20 percent or more, the governmental body shall send to the requestor a written updated itemized statement that details all estimated charges that will be imposed, including any allowable charges for labor or personnel costs. If the requestor does not respond in writing to the updated estimate in the time and manner described by Subsection (b), the request is considered to have been withdrawn by the requestor.
(d) If the actual charges that a governmental body imposes for a copy of public information, or for inspecting a paper record under § 552.271, exceeds $40, the charges may not exceed:
(1) the amount estimated in the updated itemized statement; or
(2) if an updated itemized statement is not sent to the requestor, an amount that exceeds by 20 percent or more the amount estimated in the itemized statement.
(e) An itemized statement or updated itemized statement is considered to have been sent by the governmental body to the requestor on the date that:
(1) the statement is delivered to the requestor in person;
(2) the governmental body deposits the properly addressed statement in the United States mail; or
(3) the governmental body transmits the properly addressed statement by electronic mail or facsimile transmission, if the requestor agrees to receive the statement by electronic mail or facsimile transmission, as applicable.
(f) A requestor is considered to have responded to the itemized statement or the updated itemized statement on the date that:
(1) the response is delivered to the governmental body in person;
(2) the requestor deposits the properly addressed response in the United States mail; or
(3) the requestor transmits the properly addressed response to the governmental body by electronic mail or facsimile transmission.
(g) The time deadlines imposed by this section do not affect the application of a time deadline imposed on a governmental body under Subchapter G.
