Title 49 › Subtitle SUBTITLE III— - GENERAL AND INTERMODAL PROGRAMS › Chapter CHAPTER 51— - TRANSPORTATION OF HAZARDOUS MATERIAL › § 5112
States and Indian tribes may pick which highways trucks carrying hazardous materials that must be placarded can use, and set limits or requirements for those routes, unless subsection (d) or section 5125(c) says otherwise. The Secretary must write rules for how states and tribes do this. The rules must make routes safer for local and nearby areas, require public input and consultation with other officials and affected businesses, keep routes that let trucks travel between neighboring areas, be done in a timely way, and give reasonable paths to terminals and places for fuel, repairs, rest, loading, and unloading. A state must make sure its local governments follow the rules and must settle disputes among them. When making routes, states and tribes must think about things like population, road types, kinds and amounts of hazardous material, emergency response, risks and exposure, terrain, route continuity and alternatives, effects on commerce and delays, and other factors the Secretary finds appropriate. The Secretary may not tell them how to weight those factors. The Secretary will keep and publish an updated list of active hazardous-material highway routes. Each state must tell the Secretary which agency is responsible and send its current route list at least once every 2 years and within 60 days after a route is created, changed, or ended. The Secretary will make rules to resolve routing disputes, and will decide a petition within one year. A court case about the same dispute may only start after the Secretary’s final decision or after one year, and a party must file for judicial review within 89 days of that final decision. Sections 31111, 31113, and section 127 of title 23 are not affected, and the Secretary does not have to change rules for routing radioactive material that were in effect on November 16, 1990.
