(a) General. As provided by 49 U.S.C. 31151(d), a law, regulation, order, or other requirement of a State, a political subdivision of a State, or a tribal organization relating to the inspection, repair, and maintenance of intermodal equipment is preempted if such law, regulation, order, or other requirement exceeds or is inconsistent with a requirement imposed by the Federal Motor Carrier Safety Regulations.

(b) Pre-existing State requirements—(1) In general. Pursuant to 49 U.S.C. 31151(e)(1), unless otherwise provided in paragraph (b)(2) of this section, a State requirement for the periodic inspection of intermodal chassis by intermodal equipment providers that was in effect on January 1, 2005, shall remain in effect only until June 17, 2009.

(2) Nonpreemption determinations—(i) In general. Pursuant to 49 U.S.C. 31151(e)(2), and notwithstanding paragraph (a) of this section, a State requirement described in paragraph (b)(1) of this section is not preempted if the Administrator determines that the State requirement is as effective as the FMCSA final rule and does not unduly burden interstate commerce.

(ii) Application required. Paragraph (b)(2)(i) of this section applies to a State requirement only if the State applies to the Administrator for a determination with respect to the requirement before the effective date of the final rule (June 17, 2009). The Administrator will make a determination with respect to any such application within 6 months after the date on which the Administrator receives the application.

(iii) Amended State requirements. If a State amends a regulation for which it previously received a nonpreemption determination from the Administrator under paragraph (b)(2)(i) of this section, it must apply for a determination of nonpreemption for the amended regulation. Any amendment to a State requirement not preempted under this subsection because of a determination by the Administrator may not take effect unless it is submitted to the Agency before the effective date of the amendment, and the Administrator determines that the amendment would not cause the State requirement to be less effective than the FMCSA final rule on “Requirements for Intermodal Equipment Providers and Motor Carriers and Drivers Operating Intermodal Equipment” and would not unduly burden interstate commerce.
