PHMSA proposes to amend the Hazardous Materials Regulations to adopt certain international regulations and standards related to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. These amendments are intended to maintain consistency with the latest international standards and regulations, and to reduce costs to entities or individuals within the United States or to otherwise lower the cost of regulations on the United States economy.
PHMSA is publishing this ANPRM to solicit feedback on streamlining and modernizing the Agency's regulations as they relate to the transportation of hazardous materials integral to spacecraft payloads or components.
PHMSA is updating its regulations to allow operators to apply modern risk management principles in addressing the safety of gas pipelines affected by class location changes. Relying on an approach originally developed in the 1950s, PHMSA's regulations use class locations to provide an additional margin of safety in the design, construction, testing, operation, and maintenance of gas pipelines based on population density. When the class location of a pipeline changes due to an increase in population density, an operator may need to take certain actions to confirm or to revise the maximum allowable operating pressure of a segment. Because the methods traditionally used for that purpose do not account for modern risk management principles, PHMSA has granted special permits for more than two decades allowing operators to use an integrity-management-based alternative. This final rule adopts that `IM alternative' by regulation to provide operators with an additional method for confirming or restoring the maximum allowable operating pressure of certain eligible segments that experience class location changes.
PHMSA is adopting several amendments to the Hazardous Materials Regulations to reduce unnecessary regulatory burdens associated with the safe transportation of hazardous materials, including energy products. These amendments will reduce costs for hazardous materials transporters and eliminate unnecessary regulatory burdens on fuel transportation while maintaining or increasing the level of safety provided in the Hazardous Materials Regulations.
The Pipeline and Hazardous Materials Safety Administration (PHMSA) is publishing this advance notice of proposed rulemaking (ANPRM) to obtain stakeholder input on potential revisions to the Hazardous Materials Regulations (HMR) to facilitate the safe transportation of hazardous materials using highly automated transportation systems.
PHMSA is withdrawing its proposed rulemaking that would have increased registration fees for persons who transport, or offer for transportation, certain categories and quantities of hazardous materials.
