49 CFR 601.35 - Proceedings on petitions for reconsideration.
The Administrator may grant or deny, in whole or in part, any petition for reconsideration without further proceedings. In the event he/she determines to reconsider any rule, he/she may issue a final decision on reconsideration without further proceedings, or he/she may provide such opportunity to submit comment or information and data as he/she deems appropriate. Whenever the Administrator determines that a petition should be granted or denied, he/she prepares a notice of the grant or denial of a petition for reconsideration and issues it to the petitioner. The Administrator may consolidate petitions relating to the same rule.
