Summary

Within 1 year after August 3, 2007, the Secretary of Transportation, working with the other Secretary, must document current and planned highway routes for moving radioactive and nonradioactive hazardous materials and build a GIS-based way to map them in a national registry. The Secretary must also study those routes to find measurable safety and security criteria, compare U.S., Canadian, and Mexican route rules, record concerns from the public, carriers, and governments, create guidance for State officials that fits the 13 safety-based routing criteria and the radioactive rules in subpart C of part 397 of title 49, develop a tool to test route risks and fixes, and send a report to Congress about these actions and any suggested changes to part 397. Also within 1 year after August 3, 2007, the Secretary must assess whether existing route plans for explosives and radioactive materials improve safety and security. The study must compare incident rates and measure the benefits, feasibility, and costs of requiring motor carriers with a hazardous material safety permit under part 385 of title 49 to keep, follow, and carry route plans that meet section 397.101 when moving the types and amounts listed in section 385.403, considering different carrier types. The Secretary must report the findings to Congress and may require such route plans if the assessment shows they help and do not create unreasonable costs.

(a)Route plan guidance

Not later than 1 year after August 3, 2007, the Secretary of Transportation, in consultation with the Secretary, shall—

(1)document existing and proposed routes for the transportation of radioactive and nonradioactive hazardous materials by motor carrier, and develop a framework for using a geographic information system-based approach to characterize routes in the national hazardous materials route registry;

(2)assess and characterize existing and proposed routes for the transportation of radioactive and nonradioactive hazardous materials by motor carrier for the purpose of identifying measurable criteria for selecting routes based on safety and security concerns;

(3)analyze current route-related hazardous materials regulations in the United States, Canada, and Mexico to identify cross-border differences and conflicting regulations;

(4)document the safety and security concerns of the public, motor carriers, and State, local, territorial, and tribal governments about the highway routing of hazardous materials;

(5)prepare guidance materials for State officials to assist them in identifying and reducing both safety concerns and security risks when designating highway routes for hazardous materials consistent with the 13 safety-based nonradioactive materials routing criteria and radioactive materials routing criteria in subpart C part 397 of title 49, Code of Federal Regulations;

(6)develop a tool that will enable State officials to examine potential routes for the highway transportation of hazardous materials, assess specific security risks associated with each route, and explore alternative mitigation measures; and

(7)transmit to the appropriate congressional committees a report on the actions taken to fulfill paragraphs (1) through (6) and any recommended changes to the routing requirements for the highway transportation of hazardous materials in part 397 of title 49, Code of Federal Regulations.

(b)Route plans

(1)Assessment

Not later than 1 year after August 3, 2007, the Secretary of Transportation shall complete an assessment of the safety and national security benefits achieved under existing requirements for route plans, in written or electronic format, for explosives and radioactive materials. The assessment shall, at a minimum—

(A)compare the percentage of Department of Transportation recordable incidents and the severity of such incidents for shipments of explosives and radioactive materials for which such route plans are required with the percentage of recordable incidents and the severity of such incidents for shipments of explosives and radioactive materials not subject to such route plans; and

(B)quantify the security and safety benefits, feasibility, and costs of requiring each motor carrier that is required to have a hazardous material safety permit under part 385 of title 49, Code of Federal Regulations, to maintain, follow, and carry such a route plan that meets the requirements of section 397.101 of that title when transporting the type and quantity of hazardous materials described in section 385.403, taking into account the various segments of the motor carrier industry, including tank truck, truckload and less than truckload carriers.

(2)Report

Not later than 1 year after August 3, 2007, the Secretary of Transportation shall submit a report to the appropriate congressional committees containing the findings and conclusions of the assessment.

(c)Requirement

The Secretary shall require motor carriers that have a hazardous material safety permit under part 385 of title 49, Code of Federal Regulations, to maintain, follow, and carry a route plan, in written or electronic format, that meets the requirements of section 397.101 of that title when transporting the type and quantity of hazardous materials described in section 385.403 if the Secretary determines, under the assessment required in subsection (b), that such a requirement would enhance security and safety without imposing unreasonable costs or burdens upon motor carriers.
