Text

(a) Inspection, Repair, and Maintenance of Intermodal Equipment.— (1) In general.— The Secretary of Transportation shall maintain a program to ensure that intermodal equipment used to transport intermodal containers is safe and systematically maintained.

(2) Intermodal equipment safety regulations.— The Secretary shall issue the regulations under this section as a subpart of the Federal motor carrier safety regulations.

(3) Contents.— The regulations issued under this section shall include, at a minimum—

(A) a requirement to identify intermodal equipment providers responsible for the inspection and maintenance of intermodal equipment that is interchanged or intended for interchange to motor carriers in intermodal transportation;

(B) a requirement to match intermodal equipment readily to an intermodal equipment provider through a unique identifying number;

(C) a requirement that an intermodal equipment provider identified under subparagraph (A) systematically inspect, repair, and maintain, or cause to be systematically inspected, repaired, and maintained, intermodal equipment described in subparagraph (A) that is intended for interchange with a motor carrier;

(D) a requirement to ensure that each intermodal equipment provider identified under subparagraph (A) maintains a system of maintenance and repair records for such equipment;

(E) requirements that—

(i) a specific list of intermodal equipment components or items be identified for the visual or audible inspection of which a driver is responsible before operating the equipment over the road; and

(ii) the inspection under clause (i) be conducted as part of the Federal requirement in effect on the date of enactment of this section that a driver be satisfied that the intermodal equipment components are in good working order before the equipment is operated over the road;

(F) a requirement that a facility at which an intermodal equipment provider regularly makes intermodal equipment available for interchange have an operational process and space readily available for a motor carrier to have an equipment defect identified pursuant to subparagraph (E) repaired or the equipment replaced prior to departure;

(G) a program for the evaluation and audit of compliance by intermodal equipment providers with applicable Federal motor carrier safety regulations;

(H) a civil penalty structure consistent with section 521(b) of title 49, United States Code, for intermodal equipment providers that fail to attain satisfactory compliance with applicable Federal motor carrier safety regulations; and

(I) a prohibition on intermodal equipment providers from placing intermodal equipment in service on the public highways to the extent such providers or their equipment are found to pose an imminent hazard;

(J) a process by which motor carriers and agents of motor carriers shall be able to request the Federal Motor Carrier Safety Administration to undertake an investigation of an intermodal equipment provider identified under subparagraph (A) that is alleged to be not in compliance with the regulations under this section;

(K) a process by which equipment providers and agents of equipment providers shall be able to request the Administration to undertake an investigation of a motor carrier that is alleged to be not in compliance with the regulations issued under this section;

(L) a process by which a driver or motor carrier transporting intermodal equipment is required to report to the intermodal equipment provider or the provider’s designated agent any actual damage or defect in the intermodal equipment of which the driver or motor carrier is aware at the time the intermodal equipment is returned to the intermodal equipment provider or the provider’s designated agent;

(M) a requirement that any actual damage or defect identified in the process established under subparagraph (L) be repaired before the equipment is made available for interchange to a motor carrier and that repairs of equipment made pursuant to the requirements of this subparagraph and reports made pursuant to the subparagraph (L) process be documented in the maintenance records for such equipment; and

(N) a procedure under which motor carriers, drivers and intermodal equipment providers may seek correction of their motor carrier safety records through the deletion from those records of violations of safety regulations attributable to deficiencies in the intermodal chassis or trailer for which they should not have been held responsible.

(b) Inspection, Repair, and Maintenance of Intermodal Equipment.— The Secretary or an employee of the Department of Transportation designated by the Secretary may inspect intermodal equipment, and copy related maintenance and repair records for such equipment, on demand and display of proper credentials.

(c) Out-of-Service Until Repair.— Any intermodal equipment that is determined under this section to fail to comply with applicable Federal safety regulations may be placed out of service by the Secretary or a Federal, State, or government official designated by the Secretary and may not be used on a public highway until the repairs necessary to bring such equipment into compliance have been completed. Repairs of equipment taken out of service shall be documented in the maintenance records for such equipment.

(d) Preemption Generally.— Except as provided in subsection (e), a law, regulation, order, or other requirement of a State, a political subdivision of a State, or a tribal organization relating to commercial motor vehicle safety is preempted if such law, regulation, order, or other requirement exceeds or is inconsistent with a requirement imposed under or pursuant to this section.

(e) Pre-Existing State Requirements.— (1) In general.— Except as provided in paragraph (2), 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 the date on which requirements prescribed under this section take effect.

(2) Nonpreemption determinations.— (A) In general.— Notwithstanding subsection (d), a State requirement described in paragraph (1) is not preempted by a Federal requirement prescribed under this section if the Secretary determines that the State requirement is as effective as the Federal requirement and does not unduly burden interstate commerce.

(B) Application required.— Subparagraph (A) applies to a State requirement only if the State applies to the Secretary for a determination under this paragraph with respect to the requirement before the date on which the regulations issued under this section take effect. The Secretary shall make a determination with respect to any such application within 6 months after the date on which the Secretary receives the application.

(C) Amended state requirements.— Any amendment to a State requirement not preempted under this subsection because of a determination by the Secretary under subparagraph (A) may not take effect unless—

(i) it is submitted to the Secretary before the effective date of the amendment; and

(ii) the Secretary determines that the amendment would not cause the State requirement to be less effective than the Federal requirement and would not unduly burden interstate commerce.

(f) Definitions.— In this section, the following definitions apply:

(1) Intermodal equipment.— The term “intermodal equipment” means trailing equipment that is used in the intermodal transportation of containers over public highways in interstate commerce, including trailers and chassis.

(2) Intermodal equipment interchange agreement.— The term “intermodal equipment interchange agreement” means the Uniform Intermodal Interchange and Facilities Access Agreement or any other written document executed by an intermodal equipment provider or its agent and a motor carrier or its agent, the primary purpose of which is to establish the responsibilities and liabilities of both parties with respect to the interchange of the intermodal equipment.

(3) Intermodal equipment provider.— The term “intermodal equipment provider” means any person that interchanges intermodal equipment with a motor carrier pursuant to a written interchange agreement or has a contractual responsibility for the maintenance of the intermodal equipment.
