49 CFR § 389.35 - Petitions for reconsideration.
(a) Any interested person may petition the Administrator for reconsideration of any rule issued under this part. The petition for reconsideration must be in English and submitted to the Administrator, Federal Motor Carrier Safety Administration, 1200 New Jersey Ave. SE, Washington, DC 20590–0001, or electronically submitted using the docket for the rulemaking at www.regulations.gov, and received not later than thirty (30) days after publication of the rule in the Federal Register. Petitions for reconsideration filed after that time will be considered as petitions for rulemakings filed under § 389.31 of this part. The petition for reconsideration must contain a brief statement of the complaint and an explanation as to why compliance with the rule is not practicable, is unreasonable, or is not in the public interest.
(b) If the petitioner requests the consideration of additional facts, he/she must state the reason they were not presented to the Administrator within the prescribed time.
(c) The Administrator does not consider repetitious petitions.
(d) Unless the Administrator otherwise provides, the filing of a petition under this section does not stay the effectiveness of the rule.
