Scoping language

This subpart prescribes procedures by which:
(1) Any person, including a State, political subdivision thereof, or Indian tribe, directly affected by any highway routing designation for hazardous materials may apply to the Administrator for a determination as to whether that highway routing designation is preempted under 49 U.S.C. 5125, or § 397.69 or § 397.203 of this part; and
(2) A State, political subdivision thereof, or Indian tribe may apply to the Administrator for a waiver of preemption with respect to any highway routing designation that the State, political subdivision thereof, or Indian tribe acknowledges to be preempted by 49 U.S.C. 5125, or § 397.69 or § 397.203 of this part, or that has been determined by a court of competent jurisdiction to be so preempted.
