A person subject to an order issued under this subchapter may file with the Secretary a petition-
The Secretary shall give the petitioner an opportunity for a hearing on the petition, in accordance with regulations issued by the Secretary.
After the hearing, the Secretary shall make a ruling on the petition. The ruling shall be final, subject to review as set forth in subsection (b).
Any petition filed under this subsection challenging an order, any provision of the order, or any obligation imposed in connection with the order, shall be filed within 2 years after the effective date of the order, provision, or obligation subject to challenge in the petition.
The district court of the United States for any district in which a person who is a petitioner under subsection (a) resides or carries on business shall have jurisdiction to review the final ruling on the petition of the person, if a complaint for that purpose is filed not later than 20 days after the date of the entry of the final ruling by the Secretary under subsection (a)(3).
Service of process in a proceeding may be made on the Secretary by delivering a copy of the complaint to the Secretary.
If the court determines that the ruling is not in accordance with law, the court shall remand the matter to the Secretary with directions-
The pendency of a petition filed under subsection (a) or an action commenced under subsection (b) shall not operate as a stay of any action authorized by section 7419 of this title to be taken to enforce this subchapter, including any rule, order, or penalty in effect under this subchapter.
