49 C.F.R. § 7.1 – General.

(a) This part implements the Freedom of Information Act, 5 U.S.C. 552, as amended, and prescribes rules governing the public availability of Department of Transportation (DOT) records.
(b) Subpart B of this part contains the DOT regulations concerning the public availability of:
1. (1) Records and indices that DOT is required to publish in the Federal Register pursuant to 5 U.S.C. 552(a)(1) (described in § 7.11(a)); and
2. (2) Records and indices that DOT is required to make available to the public in a reading room without need for a specific request, pursuant to 5 U.S.C. 552(a)(2) (described in § 7.12(a)).
(c) Subpart C of this Part contains the DOT regulations concerning records that may be requested from DOT under the FOIA, namely, records that DOT is not required to publish in the Federal Register or make publicly available in a reading room under 5 U.S.C. 552(a)(2)(A), (B), (C), and (E) and frequently requested records even if DOT has made them publicly available as required under 5 U.S.C. 552(a)(2)(D). Because DOT and its components make many of these records available on their Web pages (http://www.dot.gov or http://www.dot.gov/foia), requesters may find it preferable to obtain such records directly from the Web pages instead of submitting a FOIA request, if the Web pages contain records that meet their needs.
(d) Subpart D of this part contains the DOT regulations concerning time limits applicable to processing requests for records under subpart C.
(e) Subpart E of this part contains the DOT regulations concerning processing fees applicable to records made available under subpart B or requested under subpart C.
